Cilj ovog rada bio je predikcija kvalitete korisnika na temelju akcija unutar aplikacije u prvih 7 dana korištenja. Na početku su određene najvažnije akcije koje korisnik može napraviti u aplikaciji. Nakon što su skupljeni podaci, podaci su agregirani s obzirom na korisnika. Iz tako dobivenih podataka napravljena je analiza iz kojih država dolaze korisnici i kojim danima u tjednu. Nakon toga su rađeni modeli koji bi predvidjeli broj impresija na temelju broja akcija nakon 7 dana. Rezultati nisu bili dobri pa su korisnici podijeljeni u 5 kategorija ovisno o kvaliteti. Korištenjem više metoda (Multinomijalna logistička regresija, slučajne šume, Gradient Boosting i metoda glasanjem ), dobiveni su bolji rezultati. The main goal of this master thesis was to predict the quality of users based on actions within the app in the first 7 days of use. Firstly, the most important actions that a user can perform in the app were defined. Once data were collected, they were grouped by the user and then aggregated. From these data it was analyzed from which country and on which days of the week the users utilized the app. After that, models were created that would predict the number of impressions based on the number of actions made by users after the first 7 days. The results were not good, so users were divided into 5 categories depending on their quality. Using multiple methods (Multinomial Logistic Regression, Random Forests, Gradient Boosting and Voting Classifier), better results were obtained.

Inovacije so že od nekdaj gonilna sila napredka gospodarstva in civilizacije. Najpogosteje se inovacije povezujejo z raziskovalno-razvojnimi aktivnostmi pri izdelkih. Konkurenčne prednosti evropskih podjetij pa ne izhajajo zgolj iz inovacij izdelkov, temelječih na R&R delu, ampak tudi iz ne-tehniških oziroma organizacijskih inovacij, s katerimi želimo posodobiti proizvodne procese. Pri tem je zelo pomemben parameter, ki ga v doktorski disertaciji imenujemo inovacijska učinkovitost. Inovacijska učinkovitost proizvodnih podjetij je sposobnost, da z implementacijo večjega števila tehniških ali organizacijskih inovacij, kot posledic izbranih dejavnikov za povečanje inovacijske učinkovitosti, povečujejo svojo sposobnost za razvoj novih izdelkov in s tem tudi svojo donosnost. Namen disertacije je bil raziskati vpliv dejavnikov za povečanje inovacijske učinkovitosti v proizvodnih podjetjih. V ta namen je bil razvit model vplivnih dejavnikov za povečanje inovacijske učinkovitosti proizvodnih podjetij. Cilj doktorske disertacije je bil, glede na razviti model, ugotoviti vpliv medsebojnih povezav posameznih sklopov dejavnikov za povečanje inovacijske učinkovitosti proizvodnih podjetij, ugotoviti njihov vpliv na tehniške in organizacijske inovacije ter njihov neposredni vpliv na sposobnost razvoja in uvedbe novih izdelkov na trg in donosnost podjetja. Doktorska disertacija je omejena na podatke, ki smo jih pridobili s pomočjo ankete Raziskava proizvodne dejavnosti v Evropi (EMS). Naše analize so bile opravljene z naprednimi statističnimi metodami. Pregled literature je pokazal, da inovacije niso dovolj raziskane, še posebej to velja za merjenje organizacijskih inovacij. Raziskave so pokazale, da proizvodna podjetja, ki so pogosteje sposobna uporabljati inovacijske koncepte na srednjem ali celo visokem nivoju, praktično ne proizvajajo enostavnih izdelkov. V skupini šestih identificiranih vplivnih dejavnikov za povečanje inovacijske učinkovitosti obstajata dva, ki močno vplivata na razvoj novih izdelkov in njihovo lansiranje na trg. To sta subjekt sodelovanja (sodelovanje s kupci) in R&R aktivnosti. Obstajajo trije tehnični in kar sedem organizacijskih konceptov, izmed katerih večina močno vpliva na sposobnost razvoja in lansiranja novih izdelkov na trg. Innovation has always been known to be the driving force of progress in the economy and civilization. Mostlly innovations are associated with research and developement activities of products. Competitive advantages of European companies do not only arise from innovations of products based on R & D work, but also from non-technical or organizational innovations, whose intent is to update production processes. In this context, there is a very important parameter called »Innovation efficiency« in this dissertation. Innovation efficiency of manufacturing companies is ability of implementing a larger number of technical or organizational innovations as a result of selected factors to increase their inovations efficiency, increasing their capability to develop new products and therefor their profitability. The aim of the dissertation was to investigate the influence of factors for increasing innovation efficiency in production companies. For this purpose, a model of influenting factors for increasing the innovation efficiency of manufactoring companies was developed. The goal of dissertation was, according to this model, to determine the influence of connections in between of individual sets of factors in order to increase the innovation efficiency of production companies, their impact on technical and organizational innovations and their direct impact on new products and on the profitability of the company. The doctoral dissertation is limited to the data obtained by the European Manufacturing Survey (EMS). Research carried out with advanced statistical methods. A literature review has shown innovations aren´t sufficiently explored, especially for measuring organizational innovations. Researces have shown production companies, that are more often capabile to use inovation concepts on medium or even on high level, practicaly do not produce simple products. Among six identified influential factors to increase inovation efficiency there are two, which has high influence on developement of new products and their launch on market. They are subject cooperation (cooperation with buyers/customers) and R&D activities. There are three technical and even seven organizational concepts, and majority of them have strong influence on capability of developement and lounching new products on market.

Although the relationship between language proficiency and learner beliefs is generally viewed as weak, indirect, and distant, there are empirical findings which show that the relationship between syntactic complexity measures and language learning beliefs is statistically tangible. Since syntactic complexity is only one constituent of the linguistic complexity system, it seems plausible to question whether other constituents of the system are also in statistically measurable relationships with language learning beliefs. This research project explores the relationship between 25 lexical complexity measures (Lu 2012; 2014) and four subscales of language learning beliefs that are suggested for Horwitz’s (2013) Beliefs about Language Learning Inventory—BALLI 2.0 (Kovačević 2017). For three semesters (Fall 2014, Spring and Fall 2015), 152 freshman students at the International University of Sarajevo responded to BALLI 2.0 and wrote in-class exam essays which were converted into an electronic format. The results show 15 statistically significant correlation coefficients between 14 lexical complexity measures and three BALLI 2.0 subscales. Overall, it may be concluded that the relationship between lexical complexity measures and language learning beliefs is statistically detectable. The findings imply that the lexical complexity framework offers valuable opportunities for exploring how and to what extent particular individual differences manifest in foreign language production., Iako se odnos između jezičnog umijeća i vjerovanja o učenju općenito opisuje kao slab i neizravan, postoje empirijski dokazi da je veza između mjernih jedinica sintaktičke složenosti i vjerovanja o učenju jezika statistički opipljiva. Budući da je sintaktička složenost samo jedan od podsustava jezične složenosti, potrebno je ispitati jesu li i ostali podsustavi u statistički mjerljivom odnosu s takvim vjerovanjima. U ovoj se studiji istražuje veza između 25 indeksa leksičke složenosti (Lu 2012; 2014) i četiri podljestvice vjerovanja o učenju jezika izvedene iz instrumenta Vjerovanja o učenju jezika (The Beliefs about Language Learning Inventory—BALLI 2.0, Horwitz 2013; Kovačević 2017). Tijekom tri semestra (zimski semestar akademske godine 2014./2015., te ljetni i zimski semestar akademske godine 2015./2016.) prikupljen je uzorak eseja 152 studenta prve godine preddiplomskih programa na Međunarodnom sveučilištu u Sarajevu. Rezultati pokazuju 15 statistički značajnih koeficijenata korelacije između 14 indeksa leksičke složenosti i tri podljestvice BALLI 2.0. Na temelju rezultata može se zaključiti da je veza između indeksa leksičke složenosti i vjerovanja o učenju stranog jezika statistički mjerljiva. Na temelju rezultate analize može se izvesti zaključak da konstrukt leksičke složenosti predstavlja koristan okvir za proučavanje načina na koji, i opsega u kojemu se individualne razlike manifestiraju u uporabi stranog jezika.

Orienteering as a sporting and competitive as well as recreational and educational activity is increasingly being carried out by various sports associations, hikers and other amateur sportspeople. Its implementation involves class and subject teachers in schools, especially those involved in the GLOBE programme. The aim of this paper is to examine the presence of orienteering or some of its elements in the school and subject plans and programmes of both lower and higher grades of primary, as well as secondary schools in the Republic of Croatia, and a possible role of orienteering in promoting cross-curricular teaching. Because of the desire to supplement the teaching methods and forms of work with more work outside the classroom, the purpose of this paper is to contribute to forming a justified demand for incorporating orienteering in the primary school curriculum in Croatia. Since orienteering is particularly significant from the point of view of Geography and Physical Education teaching, the existing curricula of the two subjects have been analysed to identify possible cross-curricular links. This paper presents the results of the research conducted in 2017 and 2018 on a sample of 146 Geography and Physical Education teachers from Croatia. The results indicate that teachers are familiar with these activities. Although they recognize the potential in terms of the wish to integrate some contents into teaching plans and programmes, as well as contribute to cross- curricular teaching, the content of orienteering is implemented very rarely or not at all in primary, and even less, in secondary schools. The results of this research also point to the lack of class and subject teacher competences and their poor knowledge of this area.

U ovom diplomskom radu istražuje se utjecaj oborina na izdašnost izvora Rakovac. Izvor Rakovac smješten je u sjeverozapadnom dijelu Republike Hrvatske i nalazi se u blizini mjesta Koretići na području Žumberačke gore. Pri obradi podataka korišteni su podaci Državnog hidrometeorološkog zavoda o oborinama sa kišomjernih postaja Mrzlo Polje Žumberačko i Rude, te podaci o izdašnosti izvora Rakovac određeni pomoću pravokutnog oštrobridnog preljeva u razdoblju od studenog 2018. do lipnja 2019. godine. Za provedbu analize koristile su se tri statističke metode: korelacija, regresija i kroskorelacija.

Background: The recent global financial crisis in 2008 has shown that knowing the level and the dynamics of real macroeconomic variables such as GDP, industrial production, employment, private consumption, savings etc. is not enough to explain and let alone forecast these macroeconomic variables. In order to do that, one should also consider perceptions and expectations of business actors and consumers about these real variables. For example, knowing the quantitatively expressed consumer sentiment enables us to explain and forecast the direction of change in private consumption. The incorporation of the psychological variables such as consumer sentiment or economic sentiment in quantitative analysis turned out to be necessary and invaluable. Business and Consumer Surveys (BCS) play an important role in these efforts. Managers’ and consumers’ judgements about their economic surroundings, derived from BCS results, are expressed as empirically confirmed leading indicators, like economic sentiment indicator or consumer sentiment indicator. Harmonized European BCS are widely used sources of essential information because BCS measures are informative, quite intuitive, easy to interpret, very popular and timely presented in media and commented by economic analysts. They are used in scientific and professional studies as well as in general public. The literature about the relationship between consumer sentiment and private consumption is rich. The first investigations of the predictive power of the Index of Consumer Sentiment by the Survey Research Centre of the University of Michigan in forecasting consumption date back to 1960th. The main conclusion is that the consumer sentiment is a significant explanatory variable for consumption in regression model that includes lagged consumption in the model. The contribution of confidence in explaining and predicting consumption expenditures increases during periods of economic uncertainty when high volatility of consumer confidence is present (Lozza et al., 2016 ; Lahiri et al., 2016 etc.). Consumer surveys which are part of BCS are based on empirical research on consumers’ attitudes and expectations on important economic variables. Their assessments and expectations are expressed in the form of balances. Balance is the difference between positive and negative answering options, measured as percentage points of total answers for each question (variable). The next step in aggregating survey information is calculation of the Consumer Confidence Indicator (CCI). In accordance with the last revision, which was made in December 2018, the European CCI is defined as the simple average of seasonally adjusted balances of four variables: Q1 - Financial situation over last 12 months, Q2 - Financial situation over next 12 months, Q4 - General economic situation over next 12 months and Q9 - Major purchases over next 12 months. Purpose: In order to raise the CCI’s forecasting power, we propose a novel CCI which we construct by using a different weighting scheme. The weights in this newly defined CCI are obtained by using the nonlinear optimization approach. Here, the weights are determined by minimizing the root mean square error (RMSE) in simple regression model and by maximizing the correlation coefficient between the CCI and final consumption for the various time lags. Design/methodology/approach: The research presented in this paper has two parts. In the first part, the forecasting power of the revised CCI as a measure of consumer sentiment in EU is empirically examined by means of different quantitative methods. Using confusion matrix and confusion rate approach, we examine the possibility of predicting the direction of change in household final consumption expenditure based on changes in the CCI for different time lags. The (in)stability of correlation between the CCI and the consumption growth rate during the time will be examined by the rolling window correlations coefficient. In the second part of the research we modify the standardized methodology for the calculation of the CCI. The empirical analysis is based on quarterly data for four standard CCI subcomponents and y-o-y growth rate of household final consumption expenditures. The data set covers the period from 1996Q1 to 2019Q2. The data sources are European Commission and Eurostat. Findings: The results reveal that by changing the weights in calculation of the CCI the predictive power of the CCI may rise with respect to year-on-year household final consumption expenditure growth rates. Using CCI we can predict changes in household final consumption expenditure up to two quarters ahead. Correlation between analysed variables is unstable during the analysed period. Research limitations: The future research will be focused on examining differences between consumer sentiments across EU countries. The main hypothesis for the next research is that the weighting scheme will be different for the different national economies in EU. Originality/value: The added value of the paper is novel CCI weighting scheme for the EU constructed by using nonlinear optimisation techniques.

Statističkim metodama korelacije, autokorelacije i kroskorelacije obrađeni su podaci oborina i protoka za razdoblje od pet hidroloških godina tj. od 2012. do 2016. godine. Podaci su obrađivani u programu Microsoft Excel korištenjem funkcije za korelaciju te korištenjem namjenskog VBA računalnog programa za kroskorelaciju.

Diversifikacija poljoprivrednih gospodarstava obuhvaća proširenje osnovne djelatnosti poljoprivrednika na proizvode višeg stupnja dovršenosti, ponudu ugostiteljskih i turističkih usluga, kao i pružanje obrazovnih i demonstracijskih sadržaja. Svrha je diversifikacije osigurati rast i stabilnost dohotka poljoprivrednika te neizravno ublažiti nepovoljne demografske trendove u ruralnom prostoru. Cilj je rada na primjeru članica Europske unije utvrditi čimbenike diversifikacije, njihovu korelaciju sa socioekonomskim pokazateljima te odrediti u kojoj su mjeri oni prisutni u hrvatskoj poljoprivredi. U radu je, na primjeru EU28, utvrđena statistički značajna povezanost (p < 0,05) između diversifikacije poljoprivrednih gospodarstava i pokazatelja produktivnosti, veličine poljoprivrednih gospodarstava, obrazovanja poljoprivrednika i određenih tipova proizvodnje. Upravo navedeni pokazatelji svrstavaju Hrvatsku u red slabije razvijenih zemalja Europske unije, umanjujući potencijal razvoja dopunskih djelatnosti na poljoprivrednim gospodarstvima. Rezultatima rada potvrđena je pretpostavka da je diversifikacija prisutnija u zemljama s razvijenijom poljoprivredom pa je njezino uključivanje u poslovnu praksu poljoprivrednih gospodarstava sredstvo jačanja poljoprivrede i općenito ruralne ekonomije Hrvatske., The diversification of family farms includes the extension of the basic agricultural activities to value-added products or services as food processing, catering and tourism services as well as educational and demonstration content. The purpose of diversification is to increase the level and stability of farmers' income and, indirectly, to mitigate unfavorable demographic trends in rural areas. The aim of the paper is to identify the diversification factors, their correlation with socioeconomic indicators, and to determine to what extent they are present in Croatian agriculture, based on the examples from EU member states. Taken into account the examples from EU 28 the results show statistically significant correlation (p < 0.05) between the presence of diversifying activities on family farms and agricultural productivity, average farm size, farmers' education and certain types of production. The aforementioned indicators put Croatia in the line of less developed countries of the European Union, thus reducing the potential for diversifying activities in the Croatian rural economy. The results of the paper confirm the assumption that diversification is more present in countries with more developed agriculture. Consequently, its inclusion in the business practice of farmers is an instrument of strengthening Croatian agriculture and rural economy in general.

Udari munja jedan su od glavnih uzroka ispada prijenosnih visokonaponskih dalekovoda diljem svijeta. Atmosferski podaci predstavljaju novo znanje u vođenju prijenosnog elektroenergetskog sustava na temelju kojih je moguće ocijeniti utjecaj atmosferskih pražnjenja na rad nadzemne prijenosne mreže.

Lightning strikes are one of the main causes of overhead line outages. Lightning data provided by lightning locating systems introduce a new information and decision making tool in power system control upon which it is possible to assess the influence of lightning on network operation. Based on the analyses of current accomplishments key features and fields of lightning data utilization in power system control have been proposed. A detailed description of the lightning locating system, and its characteristics, is provided in the thesis. A method for the selection of sensor locations is described and a calculation of the detection efficiency parameter has been conducted as a key feature for assessment of lightning data quality. The thesis presents the developed method for correlation of transmission overhead lines and lightning. Components and processes of the developed method needed for an efficient correlation are explained. Correlated results are represented in a case study. By analyzing lightning and correlation data, using statistical regression and methods of machine learning a method for classification of transmission overhead lines based on line outages due to lightning and identification of critical line segments with high flash density has been proposed. Scientific contribution: 1. Algorithm for correlation between high voltage overhead line outages and lightning discharges; 2. Method for classification of high voltage overhead lines based on line failures caused by atmospheric discharges and identification of critical line segments with increased lightning stroke density.

Certain aspects of the red fox (Vulpes vulpes Linnaeus, 1758) and brown hare (Lepus europaeus Pallas, 1778) population dynamics in the Autonomous Province Vojvodina (Serbia) were analysed on the basis of the available data from 1978-2015. Red fox culling was taken into account as a factor affecting the abundance of brown hares. In that period, during regulated hunts a total of 399,976 foxes were culled and the annual average was 10,526 (SD = 2985). Brown hare spring counts showed fluctuations during the research period and showed a declining trend in the number of individuals. The red fox was selected for the study as the most abundant predator in this area, having the most impact on brown hares. Also, in 2010 a nationwide vaccination campaign against rabies was conducted, leading to an increase in the numbers of red foxes. However, while this led to a rise in the numbers of red foxes, the cull remained nearly the same in the following years. Analysis of the relationship between the numbers of brown hare and the red fox cull in 1978-2009 and 2010-2015 showed a significant difference in their ratio. This study shows that the numbers of red fox increased significantly following the rabies vaccination. Consequently, this is a significant factor that is affecting the brown hare population. Also, it is evident that the red fox cull needs to be increased in order to maintain the natural balance., Na temelju raspoloživih podataka iz 1978. do 2015. u Autonomnoj pokrajini Vojvodini (Republika Srbija) analizirana je dinamika populacija lisice (Vulpes vulpes linneus, 1758) i zeca običnog (Lepus europaeus Pallas, 1778). U obzir je uzet odstrel lisice kao čimbenika koji utječe na brojnost zečeva. U tom je razdoblju tijekom redovnih lovova odstrijeljeno ukupno 399 976 lisica, a godišnji prosjek iznosi 10 526 (SD = 2985). Podaci proljetnog prebrojavanja zečeva pokazuju fluktuacije tijekom istraživačkog razdoblja i trend opadanja njihova broja. za istraživanje je odabrana lisica kao najbrojniji grabežljivac na ovom području, s najviše utjecaja na zeca običnog. Također, tijekom 2010. godine provedeno je cijepljenje protiv bjesnoće diljem zemlje, što je dovelo do porasta broja lisica. No dok je broj lisica porastao, u sljedećim je godinama odstrel ostao gotovo jednak. Analize odnosa između zeca običnoga i lisice od 1978. do 2009. i od 2010. do 2015. pokazuju znakovitu razliku. Ovo istraživanje pokazuje da je broj lisica znatno povećan nakon kampanje cijepljenja protiv bjesnoće. Slijedom toga ovo je važan čimbenik koji utječe i na populaciju zeca. Također, očito je da se odstrel lisica mora povećati kako bi se održala prirodna ravnoteža.

Diversifikacija poljoprivrednih gospodarstava obuhvaća proširenje osnovne djelatnosti poljoprivrednika na proizvode višeg stupnja dovršenosti, ponudu ugostiteljskih i turističkih usluga, kao i pružanje obrazovnih i demonstracijskih sadržaja. Svrha je diversifikacije osigurati rast i stabilnost dohotka poljoprivrednika te neizravno ublažiti nepovoljne demografske trendove u ruralnom prostoru. Cilj je rada na primjeru članica Europske unije utvrditi čimbenike diversifikacije, njihovu korelaciju sa socioekonomskim pokazateljima te odrediti u kojoj su mjeri oni prisutni u hrvatskoj poljoprivredi. U radu je, na primjeru EU28, utvrđena statistički značajna povezanost (p < 0, 05) između diversifikacije poljoprivrednih gospodarstava i pokazatelja produktivnosti, veličine poljoprivrednih gospodarstava, obrazovanja poljoprivrednika i određenih tipova proizvodnje. Upravo navedeni pokazatelji svrstavaju Hrvatsku u red slabije razvijenih zemalja Europske unije, umanjujući potencijal razvoja dopunskih djelatnosti na poljoprivrednim gospodarstvima. Rezultatima rada potvrđena je pretpostavka da je diversifikacija prisutnija u zemljama s razvijenijom poljoprivredom pa je njezino uključivanje u poslovnu praksu poljoprivrednih gospodarstava sredstvo jačanja poljoprivrede i općenito ruralne ekonomije Hrvatske.

Ekonomski razvoj podržan ljudskim resursima, stabilnom inflacijom, rastom privredne aktivnosti, područje je analize brojnih autora. Pokušaji praktičnog rešavanja problema nezaposlenosti i doskorašnjeg vrlo niskog bruto domaćeg proizvoda kao i održavanja stabilne inflacije, učinilo je tokove ekonomskog razvoja neohrabrujućim, najpre zbog teške društvene i ekonomske realnosti. Prisustvo ekonomskog razvoja vremenom stvara nove potrebe privrednih subjekata i stanovništva, što se odražava na bankarski sektor i na sektor osiguranja kao intermedijara i kao pružaoca adekvatne zaštite od rizika. Analiza teorijskog okvira makroekonomskih determinanti ekonomskog razvoja i likvidnosti finansijskog sektora od presudne je važnosti za razumevanje njihove međuzavisnosti. Kada je reč o bruto domaćem proizvodu, njegov rast utiče na porast aktivnosti jedne privrede, ali i na rast tražnje za bakarskim kreditima jer poslovni subjekti imaju želju da ostvare kvalitetne poslovne projekte. U ovakvom scenariju dolazi do smanjenja likvidnih sredstava banke. Likvidnost sektora osiguranja u Srbiji trpi sve promene u nivou razvijenosti privrede jer je direktno zavistan od životnog standarda stanovništva i mogućnosti investiranja slobodnih novčanih sredstava. Likvidnost banakrskog sektora je u korelaciji sa nivoom nezaposlenosti s obzirom na to da rast nezaposlenosti smanjuje sposobnost dužnika da izmiruje svoje obaveze prema banci, a poslovne banke navodi da smanjuju svoju kreditnu aktivnost kao i broj potencijalnih klijenata. Ovakav scenario formira povećanje likvidnih sredstava u banci, ali i udeo problematičnih kredita. Likvidnost sektora osiguranja takođe je u korelaciji sa nivoom nezaposlenosti, gde visoke stope nezaposlenosti i smanjene mogućnosti stanovištva da kupuju neke od proizvoda osiguranja, umanjuju tražnju za njima i opredeljuju pojedinca da svoje potrebe zadovoljava na znatno nižem nivou. U periodima sporog ekonomskog razvoja inflacija se često koristi kao instrument za postizanje određenih ciljeva, a naročito se misli na dostizanje višeg nivoa ekonomskog razvoja i ostvarenje rasta zaposlenosti. Visoke stope inflacije smanjuju kreditnu aktivnost banaka što posledično povećava likvidne rezerve banke. Međuzavisnost postoji jer rast potrošačkih cena deluje na smanjenu ukupnu tražnju koja opet usporava privrednu aktivnost i tražnju za kreditima. Dejstvo inflacije na likvidnost sektora osiguranja u Srbiji nije identifikovano. Na osnovu različitih teorijskih i empirijskih rezultata, kao predmet istraživanja doktorske disertacije postavlja se analiza međuzavisnosti odabranih makroekonomskih determinanti ekonomskog razvoja i likvidnosti finansijskog sektora. Uvažavajući navedeno, moguće je ukazati na makroekonomske determinante ekonomskog razvoja sa najvećom međuzavisnošću sa likvidnošću bankarskog sektora i sektora osiguranja. Kao cilj istraživanja doktorske disertacije postavlja se ocena da li i na koji način varijacije makroekonomskih determinanti ekonomskog razvoja utiču na izloženost finansijskog sektora riziku likvidnosti. U okviru definisanog predmeta istraživanja primenjene su metode istraživanja poput komparativne metode, deskriptivne statistike, korelacione analize, linearne logističke regresije, nad podacima makroekonomskih determinanti ekonomskog razvoja i likvidnosti bankarskog sektora i sektora osiguranja. Pružen je zaključak u kojem se navodi koji finansijski sektor tj. njegova likvidnost, ostvaruje veću međuzavisnost sa makroekonomskim indikatorima ekonomskog razvoja, čime je obogaćeno i upotpunjeno naučno saznanje Economic development supported by human resources, stable inflation, growth of economic activity has been study issues of numerous authors. Attempts to practically solve the unemployment problem and the current very low gross domestic product, as well as to maintain stable inflation, have made the flow of economic development unsustainable, primarily due to the difficult social and economic reality. The presence of economic development over some time creates new needs of business entities and the population, which is reflected in the banking sector and the insurance sector as intermediaries and as providers of adequate risk protection. The analysis of the theoretical framework of macroeconomic determinants of economic development and liquidity of the financial sector is crucial for understanding their interdependence. When it comes to gross domestic product, its growth affects the increase in the economic activity but also the growth in demand for bank loans, as business entities have a desire to achieve quality business projects. In this scenario there is a decrease in the bank's liquid assets. The liquidity of the insurance sector in Serbia suffers from all changes in the level of economic development because it is directly dependent on the living standard of the population and the possibility of investing free cash. Liquidity of the banking sector is in correlation with the level of unemployment, since the growth of unemployment reduces the ability of the borrower to settle its obligations towards the bank, and commercial banks state that they reduce their lending activity and the number of potential clients. This scenario forms the increase of liquid assets in the bank, as well as the share of problem loans. Liquidity of the insurance sector also depends on the level of unemployment, where high unemployment rates and reduced ability to buy some of the insurance products reduce the demand for them and force an individual to satisfy their needs at a significantly lower level. In periods of slow economic development, inflation is often used as an instrument for achieving certain goals, and in particular it means to achieve a higher level of economic development and achieve employment growth. High inflation rates reduce the lending activity of banks, which consequently increases the bank's liquid reserves. Interdependence exists because the growth of consumer prices affects the reduced total demand, which again slows down economic activity and demand for loans. The effect of inflation on the liquidity of the insurance sector in Serbia has not been identified. Based on different theoretical and empirical results, the research issue of the doctoral thesis is the analysis of the interdependence of the selected macroeconomic determinants of economic development and liquidity of the financial sector. Taking into account the abovementioned, it is possible to point out to the macroeconomic determinants of economic development with the highest interdependence with the liquidity of the banking sector and the insurance sector. The goal of the research in this doctoral dissertation is to assess whether and how the variations of macroeconomic determinants of economic development influence the exposure of the financial sector to the liquidity risk. Within the defined research problem, research methods such as comparative method, descriptive statistics, correlation analysis, linear logistic regression, data on macroeconomic determinants of economic development and liquidity of the banking sector and the insurance sector were applied. A conclusion has been drawn that states which financial sector, i.e. its liquidity, achieves greater interdependence with macroeconomic indicators of economic development, which enriched and broadened scientific knowledge.

Na osnovu rezultata studije Globalnog Opterećenja Bolesti (engl. Global Burden of Disease-GBD) bol u vratu, sa ili bez iradirajućeg bola u jedan ili oba gornja ekstremiteta je na četvrtom mestu po funkcionalnoj onesposobljenosti pacijenata. Cervikalna radikulopatija (CR) se definiše kao bol u vratu i gornjim ekstremitetima uzrokovan kompresijom i/ili iritacijom jednog ili više cervikalnih spinalnih nerava i/ili korenova. Klinička manifestacija CR je veoma široka i uključuje bol, senzitivnu i motornu disfunkciju, sniženje i/ili gubitak mišićno-tetivnih refleksa na gornjim ekstremitetima ili kombinaciju predhodno navedenih kliničkih karakteristika. Podaci u literaturi pokazuju da pacijenti sa bolom u vratu i gornjim ekstremitetima imaju intenzivniji bol, značajniju funkcionalnu onesposobljenost i smanjenje kvaliteta života od pojedinaca koji osećaju samo bol u vratu. Identifkacija faktora koji utiču na funkcionalnu sposobnost osoba sa CR prvenstveno iz domena kliničkih karakteristika omogućava dalja istraživanja mehanizama povezanosti bola, kliničkog i funkcionalnog statusa, a krajnji cilj je poboljšanje funkcionalne sposobnosti pacijenata kroz optimalno planiranje terapijskog protokola i širenje opsega terapijskih intervencija. CILJ ISTRAŽIVANJA:1.Ispitivanje psihometrijskih karakteristika indeksa onesposobljenosti zbog bola u vratu (engl. Neck Disability Index-NDI), uključujući lingvističku validaciju i kulturološku adaptaciju srpske verzije upitnika; 2. Procena funkcionalne sposobnosti (FS) osoba sa cervikalnom radikulopatijom; 3. Ispitivanje povezanosti kliničkih parametara sa funkcionalnom sposobnosti osoba sa cervikalnom radikulopatijom; 4.Određivanje potencijalnih prediktora funkcionalne sposobnosti osoba sa cervikalnom radikulopatijom iz domena kliničkih, ali i sociedomografskih i bihejvioralnih karakteristika. METOD: Istraživanje je dizajnirano kao studija preseka, a ciljna populacija su bile osobe sa dijagnozom cervikalne radikulopatije. U studiju je bilo uključeno ukupno 100 ispitanika, od kojih je 50 ispitanika imalo CR, dok je 50 zdravih ispitanika uključeno u kontrolnu grupu. Kriterijumi za uključivanje pacijenata u studiju su bili: pacijenti starosti izmedju 18 i 65 godina; pacijenti koji su imali oštar i iradirajući bol u vratu i rukama koji je trajao kraće od 12 meseci; pacijenti sa elektromioneurografski utvrđenim znacima cervikalne radikulopatije; pacijenti sa neuroradiološkim utvrđenim znacima hernijacije diskusa i/ili degenerativnog oboljenja cervikalne kičme; razumevanje pisanog materijala lingvistički adaptiranog za srpski jezik; dobrovoljno potpisan obrazac objašnjenja i pristanka za učešće u studiji... Based on the results of the Global Burden of Disease (GBD), pain in the neck, with or without irradiation pain in one or both of the upper limbs, is the fourth most commonly reason of functional disability. Cervical radiculopathy (CR) is defined as neck pain and upper extremities caused by the compression and / or irritation of one or more cervical spinal nerves and / or roots. The clinical manifestation CR is very wide and includes pain, sensory and motor dysfunction, decreased and / or loss of muscle-tendon reflexes on the upper extremities or a combination of previously stated clinical features. Data in the literature show that patients with neck pain and upper extremities have more intense pain, more functional disability, and lower quality of life than individuals who feel only neck pain. Identification of factors that affect the functional ability of persons with CR primarily from the domain of clinical features allows further investigation of mechanisms of association of pain, clinical and functional status, and the ultimate goal is to improve functional ability of patients through optimal planning of the therapeutic protocol and expanding the scope of therapeutic interventions. AIM: 1. Examination of psychometric characteristics of the Neck Disability Index (NDI), including linguistic validation and cultural adaptation of the Serbian version of the questionnaire; 2. Evaluation of the functional ability of patients with cervical radiculopathy; 3. Investigation of the correlation between clinical characteristics and functional ability in patients with cervical radiculopathy; 4. Determination of potential predictors of the functional ability of persons with cervical radiculopathy from the domain of clinical, but also sociodemographic and behavioral characteristics. METHOD: The study was designed as a cross-sectional study and the target population were people with diagnosis of CR. The study included a total of 100 participants, 50 of whom had CR, while 50 healthy subjects were included in the control group. Inclusion criteria were: patients between the ages of 18 and 65; patients who had severe neck and arm pain lasting less than 12 months; patients with determined signs of cervical radiculopathy by electromyneurography; patients with neuroradiologically established signs of disc herniation and / or degenerative disease of the cervical spine; understanding of written material linguistically adapted for the Serbian language; a voluntary signed form of explanation and consent for participation in the study. The inclusion for the involvement of subjects in the control group was the absence of pain and discomfort associated with the cervical spine in the past one year...

Krški izvori Rumin Veliki i Rumin Mali nalaze se u slivu rijeke Cetine, nizvodno od akumulacije Peruča. Izgradnjom i puštanjem sustava akumulacija Buško Blato – HE Orlovac 1973. godine u funkciju, dogodile su se promjene hidroloških režima ovih izvora. U radu su analizirani i uspoređeni hidrološki režimi prije i poslije izgradnje sustava. Korišteni podatci su srednji dnevni protoci na vodomjernim postajama Rumin Veliki (1948. – 2016.) i Rumin Mali (1950. – 2016.) te podatci o dnevnim oborinama, srednjim dnevnim temperaturama i relativnim vlažnostima zraka na meteorološkim postajama Livno (1996. – 2017.) i Sinj (1995. – 2016.). Analizirani su režimi godišnjih, mjesečnih i dnevnih oborina, temperature i relativnih vlažnosti zraka na Livanjskom i Sinjskom polju, te režimi godišnjih, mjesečnih i dnevnih protoka na izvorima Rumin Veliki i Rumin Mali. Nakon toga napravljena je korelacijska i regresijska analiza između: 1. ukupnih godišnjih oborina na postajama Livno i Sinj i srednjih godišnjih protoka oba izvora te 2. godišnjih, mjesečnih i dnevnih protoka predmetnih izvora. Nakon puštanja sustava u funkciju, protoci su se snizili na oba izvora. Prosječni srednji godišnji protok na izvoru Rumin Veliki se snizio za 11,6 m3/s (za 62,4%) , a na izvoru Rumin Mali za 1,02 m3/s (za 37,2%). U recentnom razdoblju izvori se prihranjuju vodama iz vlastitog (unutrašnjeg) sliva. Karst springs Rumin Veliki and Rumin Mali are located in the Cetina River basin, downstream from the Peruča reservoir. With the construction and putting into operation the system Buško Blato reservoir – HPP Orlovac in 1973., there have occurred some changes in the hydrological regime of these springs. This paper presents analysis and comparison of the hydrological regimes before and after the construction of the system. Used data are daily average discharges at the water stations Rumin Veliki (1948 - 2016) and Rumin Mali (1950 - 2016) and data on daily precipitation, as well as daily average temperatures and relative humidity at meteorological stations Livno (1996 - 2017) and Sinj (1995 - 2016). This paper also analyzes annual, monthly and daily precipitation, as well as, temperature and relative humidity in the fields of Livno and Sinj and it analyzes annual, monthly and daily discharges at the springs Rumin Veliki and Rumin Mali. Further on, it gives correlation and regression analysis between: 1. total annual precipitation at meteorological stations Livno and Sinj and the mean annual discharges of both springs and 2. annual, monthly and daily discharges of the springs in question. On both springs discharges were reduced after the system was put into operation. The average annual discharge was reduced by 11,6 m3/s ( for 62,4%) on spring Rumin Veliki and by 1,02 m3/s (for 37,2%) on spring Rumin Mali. In recent period both springs are fed by water from their own basins.

Namen magistrske naloge je bil preučiti uporabnost indeksa stanja vegetacije in standardiziranega padavinskega indeksa za opazovanje suše s satelitskimi posnetki. Uporabnost indeksov smo preverjali na območju meteoroloških postaj Lendava, Ljubljana Bežigrad, Novo mesto in Postojna, na podlagi izbranih točk, za katere imamo podatke o dejanski rabi tal (listnati gozd, mešana raba, polja, travniki, vinogradi, iglasti gozd in nasadi). Za izbrane točke smo pridobili podatke o časovnih serijah produkta MODIS MOD13Q1 in izračunali indeks stanja vegetacije. Izračunane vrednosti standardiziranega padavinskega indeksa (SPI1, SPI2, SPI3, SPI4, SPI6, SPI9, SPI12) smo primerjali z indeksom stanja vegetacije. Primerjavo smo naredili z namenom, da bi ugotovili kako sta indeksa med seboj koreliranega oz. s tem bi pridobili podatek, po kolikšnem času se vegetacija odzove na primanjkljaj padavin. Na podlagi rezultatov smo komentirali uporabnost indeksov in podali bistvene ugotovitve. The purpose of the Master’s Thesis was to study the usefulness of Vegetation Condition Index and Standardized Precipitation Index, for observing droughts with satellite imagery. The usefulness of the indices was checked in the area of meteorological stations Lendava, Ljubljana Bežigrad, Novo mesto and Postojna, for which we have information on actual land use (deciduous forest, mixed land-use, fields, meadows, vineyards, coniferous forest and plantations). For selected points, we obtained data on time series MODIS MOD13Q1 and calculated Vegetation Condition Index. The calculated values of the Standardized Precipitation Index (SPI1, SPI2, SPI3, SPI4, SPI6, SPI9, SPI12) we compared with Vegetation Condition Index. A comparison was made in the order to find out, how the indices were correlated with each other. This would provide information on the extent, to which the vegetation response to the precipitation deficit. Based on the results, we commented on the usefulness of the indices and made important findings.

Uvod: Klinična uporabnost testa dosega z nogo v treh smereh je odvisna od zanesljivosti testa. Test dosega z nogo v treh smereh (angl. modified Star Excursion Balance Test) je dinamični test ravnotežja, ki zahteva primerno zmogljivost, fleksibilnost in propriocepcijo. Čeprav je ocena dinamičnega ravnotežja izjemno pomembna za določanje stanja ravnotežja osebe, je celostna ocena nadzora drže posameznika nemogoča brez pridružene ocene statičnega ravnotežja, za katero se pogosto uporablja test stoje na eni nogi. Namen: Namen raziskave je bil oceniti zanesljivost testa dosega z eno nogo v treh smereh pri zdravih, mlajših odraslih ter ugotoviti korelacijo med omenjenim testom in testom stoje na eni nogi pri istem vzorcu. Metode dela: V raziskavo je bilo vključenih 30 zdravih mlajših odraslih (starost 21.0 ± 0.99 let). Preiskovanci so teste izvajali dvakrat s presledkom enega tedna. Posamezen preiskovanec je na začetku izvedel test dosega z nogo v treh smereh, nato pa nadaljeval s testom stoje na eni nogi. Rezultati: Za vse tri smeri je izmerjen koeficient intraklasne korelacije, ki je znašal za anteriorno smer 0.92, medtem ko je pri posteromedialni in posterolateralni smeri znašal 0.95, kar avtorji ocenjujejo kot odlično zanesljivost testa. Skupni rezultati korelacije med testi v prvem in drugem testiranju kažejo, da je v prvem testiranju Pearsonov koeficient korelacije znašal r = 0.449 s stopnjo značilnosti p = 0.013, medtem ko je v primeru drugega testiranje ta rezultat bil r = 0.461 s stopnjo značilnosti p = 0.010. Glede na to, da je korelacija med testi značilna pri p < 0.05, lahko na osnovi pridobljenih rezultatov trdimo, da rezultati testa dosega z nogo v treh smereh šibko korelirajo z rezultati testa stoje na eni nogi pri zdravih mlajših odraslih. Razprava in sklep: Na podlagi pridobljenih rezultatov lahko sklepamo, da je test dosega z nogo v treh smereh zanesljivo merilno orodje za oceno dinamičnega ravnotežja pri zdravih mlajših odraslih. Test stoje na eni nogi pozitivno, čeprav šibko korelira s testom dosega v treh smereh. Introduction: The clinical validity of the modified Star Excursion Balance test depends on the reliability of the test itself. The modified Star Excursion Balance Test is a dynamic balance test that requires appropriate strength, flexibility and proprioception. Although the dynamic balance assessment itself is extremely important for determining a person's condition, an overall assessment of individuals postural control is impossible without an associated assessment of the static balance, for which the One Leg Stance Test is often used. Purpose: The aim of the study was to evaluate the reliability of the Star Excursion Balance Test in healthy young adults, and to determine the correlation between this test and the One Leg Stance Test in this sample. Methods: The study included 30 healthy young adults (age 21.0 ± 0.99 years). The subjects were tested twice within a period of two weeks. Each subject first performed the Star Excursion Balance Test and, after his successful completion, started with the One Leg Stance Test. Results: For all three directions, the intraclass correlation coefficient was measured, and it was found that the anterior direction had ICC = 0.92, while for posteromedial as well as posterolateral had ICC = 0.95, which means high reliability of the test. The total results show that in the first testing the Pearson correlation coefficient was r = 0.449 with p = 0.013, while in the second testing this result was r = 0.461 with p = 0.010. Considering that the correlation between the tests is statistically relevant for p

At the Orlica fault in the Krško basin, combined barasol detectors were buried in six boreholes, two along the fault itself and four on either side of it, to measure and record radon activity, temperature and pressure in soil gas every 60 minutes for four years. Data collected have been analysed in a manner aimed at distinguishing radon anomalies resulting from environmental parameters (air and soil temperature, barometric pressure, rainfall) from those caused solely by seismic events. The following approaches have been used to identify anomalies: (i) ± 2σ deviation of radon concentration from the seasonal average, (ii) correlation between time gradients of radon concentration and barometric pressure, and (iii) prediction with regression trees within a machine learning program. In this paper results obtained with regression trees are presented. A model has been built in which the program was taught to predict radon concentration from the data collected during the seismically inactive periods when radon is presumably influenced only by environmental parameters. A correlation coefficient of 0.83 between measured and predicted values was obtained. Then, the whole data time series was included and a significantly lowered correlation was observed during the seismically active periods. This reduced correlation is thus an indicator of seismic effect. Vzdolž preloma Orlica v Krški kotlini merimo koncentracijo radona v talnem zraku z avtonomnimi kombiniranimi instrumenti barasoli. Na šestih lokacijah, dve na samem prelomu in po dve na vsaki strani preloma, merimo aktivnost radona, temperaturo in zračni tlak štiri leta vsakih 60 minut. Rezultate meritev smo analizirali z namenom, da bi razlikovali med anomalijami radona, ki jih povzročajo hidrometeorološki vplivi (temperatura zraka in tal, zračni tlak in količina padavin) in tistimi, ki jih povzroča seizmična aktivnost. Za identifikacijo anomalij smo uporabili naslednje metode: (i) ± 2σ odklon koncentracije radona od sezonskih povprečnih vrednosti, (ii) korelacijo med časovnim gradientom koncentracije radona in časovnim gradientom zračnega tlaka, in (iii) regresijska drevesa s programi strojnega učenja. V tem članku predstavljamo rezultate, ki smo jih dobili z regresijskimi drevesi. Model je bil zgrajen v času seizmične neaktivnosti, v času, ko na koncentracijo radona vplivajo le hidrometeorološki parametri. Na podlagi tega lahko model napove koncentracijo radona za neseizmično obdobje s korelacijskim koeficientom 0,83. V času seizmične aktivnosti je napoved koncentracije radona veliko slabša. To znižanje korelacijskega koeficienta kaže na vpliv seizmične aktivnosti.

U ovom radu identificiran je utjecaj praga TE – TO na podzemne vode neposrednog zaobalja. Analizirani su podaci iz razdoblja od 1. siječnja 1994. do 31. prosinca 2000. godine. Za utvrđivanje veze korištene su statističke metode korelacije, regresije i kroskorelacije. Obrada podataka izvršena je u programu Microsoft Excel, korištenjem funkcije za korelaciju, primjenom odabranih regresijskih modela te namjenskog VBA programa za kroskorelaciju. Metodom korelacije dobiveni su koeficijenti koji ukazuju na pozitivnu korelaciju, odnosno da je porast visine vodostaja praćen porastom razine podzemne vode. Metodom linearne regresije dobiveni su koeficijenti determinacije. U jednom slučaju utvrđeno je kako regresijski model dobro predstavlja mjerene vrijednosti, dok u preostala tri slučaja regresijski model ne predstavlja dobro mjerene vrijednosti. Metodom kroskorelacije dobiveni su koeficijenti korelacije na temelju kojih su određeni vremenski podaci, odnosno zaostajanje jedne varijable za drugom., In this thesis, the impact of the river dam near Thermal powerplant Zagreb on surrounding groundwater level had been identified. Data ranging from January 1st 1994 to December 31st 2000 was analysed. In order to determine the data relation, statistical methods correlation, regression and cross correlation had been used. Data analysis had been done in Microsoft Excel Software using correlation command, applying chosen regression models and with appropriate VBA code. Using correlation methods, correlation coefficients were determined. They show positive correlation, thus confirming water level growth followed by groundwater level growth. Using linear regression, coefficients of determination were determined. It had been shown with one result that the regression model represents valued measures well. In the rest of the cases, it had been shown that regression model represents valued measures poorly. Cross correlation method enabled calculating correlation coefficients which determined the time displacement, showing one variable lag in relation to another variable.

Cilj ovog rada je proučavanje hidroloških odnosa dvaju susjednih krških izvora Jadro i Žrnovnica u Hrvatskoj. Rad se fokusira na utvrđivanju utjecaja temperature, relativne vlažnosti, oborina i protoka na ponašanje i odnose dvaju izvora. Parcijalna korelacijska analiza vremenskih serija implicira da utjecaj kontrolne vremenske serije na kroskorelacijsku funkciju između ulazne i izlazne vremenske serije može biti detektiran pomoću korelacijskog koeficijenta između ulazne i kontrolne vremenske serije, i kroskorelacijske funkcije između kontrolne i izlazne vremenske serije. Napajanje podzemnih voda ovisi o procesu evapotranspiracije i oborinama, dakle temperatura zraka, relativna vlažnost i oborine kontroliraju prostornu i vremensku distribuciju ovih procesa. Najveći doprinos ovog rada leži u korištenju obične korelacije i parcijalne korelacijske analize prvog reda za karakterizaciju funkcioniranja i odnosa dvaju susjednih krških izvora u sušnoj i kišnoj hidrološkoj godini koristeći satne podatke. Dokazano je da je u slučaju susjednih krških izvora protok svakog pojedinog izvora ima utjecaj na korelaciju oborineprotok drugog izvora. Demonstrirani pristup predstavlja poboljšanje u analizi odnosa susjednih krških izvora u sušnim i kišnim periodima, i može se primijeniti na bilo koje susjedne krške izvore., The objective of this work is the study of two adjacent karst springs Jadro and Žrnovnica in Croatia. This work focuses on the effects of temperature, relative humidity, rainfall and discharges on the behaviour and relations of two adjacent karst springs. Partial correlation analysis implies that the impact of the control signal on the cross-correlation function between the input and output signal can be detected from the correlation coefficient between the input signal and control signal and from the cross-correlation function between the control signal and output signal. The groundwater recharge depends on the process of evapotranspiration and rainfall, so air temperature, relative humidity and rainfall control the spatial and temporal distribution of this process. The major contribution of the paper relies on the utilization of simple correlation and fist-order partial correlation analysis to characterize the functioning and relations of two adjacent karst springs in a dry and wet hydrological year by using hourly data. It has been confirmed that in the case of adjacent karst springs the discharge of each spring has effect on the rainfall-discharge correlation of the other spring. The demonstrated approach represents an improvement in investigating the relations of adjacent karst springs in dry and wet periods, and can be applied on any adjacent karst springs.

Global climate changes have caused a significant weather oscillation. The objectives of this study were to determine the influence of weather conditions on the association of soybean seed yield and yield components, to find out the magnitude and effect of each component and their reaction to environmental stress. Seventy-four soybean varieties from nine geographical origins were studied during two seasons (2015 with less rainfall and increased temperatures and 2016 with increased humidity and moderate temperatures) at the Croatian Centre for Agriculture, Food and Rural Affairs in Osijek, Croatia. Correlation and path analysis were used to examine the association of the studied traits. The variance analysis revealed significant (P, Globalne klimatske promjene uzrokuju sve veće vremenske oscilacije. Ciljevi ovog istraživanja bili su odrediti utjecaj vremenskih čimbenika na povezanost prinosa zrna soje i komponenti prinosa, ispitati jačinu i učinak svake komponente te njihovu reakciju na okolišni stres. Tijekom dvije vegetacijske sezone (2015. sa sušnim uvjetima i povišenim temperaturama i 2016. s vlažnim vremenskim uvjetima i umjerenim temperaturama) pri Hrvatskom centru za poljoprivredu, hranu i selo u Osijeku proučavane su sedamdeset četiri sorte soje podrijetlom iz devet različitih geografskih izvora. Za ispitivanje povezanosti proučavanih svojstava korišteni su korelacijska i path analiza. Analiza varijance pokazala je značajan (P

The primary purpose of this study was to determine the relationships between fitness tests, and the results in selected gymnastic skills in students enrolled in Physical education teacher education (PETE) program. The secondary purpose of this study was to establish which assessment tests best represent, or correspond, with selected gymnastics skills. A total of 170 male students were recruited from the Faculty of Sport and Physical Education of the University of Priština to participate in the study. The participants were tested for several fitness tests, and performance in selected gymnastic skills. There were significant correlations between the results of fitness tests and performance in gymnastic skills. Significant correlation was found between flexibility, abdominal muscle strength and endurance and performance in gymnastics. Moreover, several fitness tests could serve as significant predictors for performance in several gymnastic skills. The results of this research suggest that, among the students of the Faculty of Sport and Physical Education, abdominal strength and flexibility are a significant predictor for the successful acquisition of the gymnastics program content., Osnovna svrha ove studije bila je utvrditi odnose između kondicijskih testova i rezultata odabranih gimnastičkih vještina kod studenata odabranih za program obrazovanja učitelja tjelesnog odgoja. Sekundarna svrha te studije bila je utvrditi koji testovi procjene najbolje predstavljaju ili odgovaraju odabranim vještinama gimnastike. Na Fakultetu sporta i tjelesnog odgoja Sveučilišta u Prištini odabrano je ukupno 170 muških studenata koji su sudjelovali u studiji. Sudionici su testirani putem nekoliko kondicijskih testova i kroz izvedbu u odabranim gimnastičkim sposobnostima. Pronađene su značajne korelacije između rezultata kondicijskih testova i izvedbi u gimnastičkim vještinama. Pronađena je značajna povezanost između fleksibilnosti, snage trbušnih mišića i izdržljivosti i izvedbe u gimnastici. Štoviše, nekoliko kondicijskih testova moglo bi poslužiti kao značajan prediktor za izvedbu u nekoliko gimnastičkih vještina. Rezultati ovog istraživanja upućuju na zaključak da su među studentima Fakulteta sporta i tjelesnog odgoja, abdominalna snaga i fleksibilnost značajan prediktor uspješnog savladavanja programskih sadržaja gimnastike.

The yield components of pumpkin seeds and fruits were examined in Stara Pazova in period 2016-2017. Different pumpkin populations were enrolled in the study, grown at following locations in Serbia: Šabac, Šumadija and Negotin. Pumpkin originating in Šumadija was found to produce highest seed yield (0.738 t haι) and possess greatest average seed mass per fruit (110.7 g). Highest fruit yield (95.1 t haι) and greatest fruit mass (14.5 kg) were recorded in population from Šabac. A significant correlation (p ≤ 0.001) was found between fruit yield and fruit mass, as well as between seed yield and seed mass per fruit. Based on two-year experiment, following conclusions can be drawn: origin of population greatly affects all components of seed and fruit yield; high yields of seeds in Northern Serbia can be produced by cultivating population from Šumadija, whereas high yields of fruits can be produced by cultivating population from Šabac. Istraživanje komponenti prinosa semena i ploda populacija bele bundeve ispitivane su tokom 2016. i 2017. godine na lokaciji severne Srbije u Staroj Pazovi. Za istraživanje korišćene su populacije bele bundeve poreklom sa tri različita lokaliteta iz Srbije: zapadna (Šabac), centralna (Šumadija) i istočna (Negotin). Dobijeni rezultati ukazuju da poreklo populacije značajno (r lt 0,01) utiče na sve komponente prinosa bundeve. Kod populacije poreklom iz Šumadije utvrđen je najveći prinos semena (0,738 t haι) i najveća prosečna masa semena po plodu (110,7 g), dok je najveći ukupan prinos ploda bundeve (95,1 t haι) i najveća prosečna masa ploda (14,3 kg) konstatovana kod populacije iz Šabca. Zabeležena je visoka korelaciona zavisnost (p≤0,001) između ukupnog prinosa ploda i prosečne mase ploda, kao i kod ukupnog prinosa semena i prosečne mase semena po plodu. Na osnovu rezultata dvogodišnjih istraživanja uticaja populacije i ekoloških uslova na komponente prinosa semena i ploda bundeve, možemo izvesti sledeće zaključke: - poreklo populacija bundeve značajno utiče na sve komponente prinosa za dobijanje visokih prinosa semena bundeve u uslovima severne Srbije možemo preporučiti populaciju poreklom iz Šumadije, dok za proizvodnju ploda treba gajiti populaciju bundeve iz Šabca.

Posmična čvrstoća tla je vrijednost posmičnog naprezanja pri slomu duž klizne plohe u tlu. Sva mjerenja izvršena su u Geotehničkom laboratoriju Geotehničkog fakulteta u Varaždinu, na uređaju za izravni posmik s kontroliranom deformacijom. U svrhu dokazivanja čvrste korelacije između vršnog kuta unutrašnjeg trenja i indeksa plastičnosti, ispitan je veći broj uzoraka glinovitog tla različitog indeksa plastičnosti, izračunatog na temelju granice tečenja i granice plastičnosti, dobivenih laboratorijskim klasifikacijskim testovima. Uzorkovanje i ispitivanje materijala provedeno je u periodu od siječnja 2007. do lipnja 2010. godine, a materijal je uzet na više lokacija u Republici Hrvatskoj. Provedena ispitivanja i rezultati mjerenja u ovom završnom radu potvrđuju ona poznatih domaćih stručnjaka poput Ortolana i Mihalineca. Interpretacija rezultata jasno dokazuje izraženu zavisnost između indeksa plastičnosti i kuta unutrašnjeg trenja koherentnog tla.

Cilj ovoga rada jest doprinijeti nastavi Polifonije kao glazbeno-teorijskoj, ali i glazbeno-pedagoškoj disciplini. Za realizaciju sveobuhvatne nastave potrebni su kvalitetni materijali i izvori, kao i stručni te kreativni nastavnici. Kako bi se nastavi Polifonije pristupilo sustavno i temeljito, u uvodnom dijelu ovoga rada obuhvatila se obrada pojmova vezanih uz polifoniju i sam njen razvoj kao i razvoj načina poučavanja te materije. Slijedi detaljan prikaz nastavnih planova i programa nakon čega se dolazi do ključnog dijela cijeloga rada, do analize odabranih udžbenika te njihove međusobne usporedbe kako bismo dobili objektivan prikaz kvaliteta pojedinog udžbenika. Udžbenici su također uspoređeni s propisanim nastavnim programom kako bismo ustanovili do koje su mjere s njima usklađeni. Na kraju rada predloženi su i savjeti na koji način unaprijediti nastavni proces, u nadi da će se nastavnici sami odvažiti u daljnje istraživanje u svrhu poboljšanja sveukupne kvalitete nastave predmeta Polifonija u Republici Hrvatskoj.

Važnost korelacije; međusobnog odnosa, uzajamne zavisnosti bitna je za povezivanje harmonične cijeline. Kuda god pogledamo naići ćemo na korelativnost, a to je strukturalnost ili građa koju prepoznajemo kao unutrašnje načelo koje gradi neki oblik. Jer sve što nas okružuje možemo prevesti na likovni jezik; bojom, olovkom, glinom.... No, taj prijevod neće biti doslovan, nego će ga povezivati unutrašnji sadržaji. Problematika je ta što se danas u školama radi uglavnom na povezivanju likovnih ilustracija sa tekstom iz hrvatskog jezika, doživljajem glazbe iz glazbene kulture, slikanjem biljaka i životinja iz prirode i društva. Te se ona vrlo često odnosi na usko shvaćanje i gledanje u traženju srodnog motiva iz sadržaja drugih odgojno obrazovnih područja. No, korelacija ne smije ići na štetu likovno-estetskih sadržaja jer su oni uz doživljaj djece, glavni i neodvojivi sadržaji u ovom odgojno obrazovnom području. Cilj je razviti suodnos i povezanost u harmoničnu cijelinu. Korelaciju treba shvatiti integralno, te treba obratiti pažnju da se komponente svih odgojno obrazovnih područja prožmu u nizu raznovrsnih oblika rada.

Mass concentrations of particulate matter (PM) fractions were measured in educational buildings in the city of Nis, Serbia. Two sampling campaigns were conducted in winter periods. The first campaign was in the period from 21 February to 15 April 2010 at the Faculty of Occupational Safety (FOS) and the second campaign was from 20 March to 4 April 2013 at the primary school Void Karadorde (VK). PM measurements were carried out with low volume samplers Sven/Leckel LVS3. The average daily PM10 concentration inside the FOS (47.0 +/- 21.8 mu g/m(3)) was lower than PM10 concentration in outdoor air (50.7 +/- 28.1 mu g/m(3)). The average daily PM10 concentration inside the VK (54.6 +/- 17.6 mu g/m(3)) was higher than in outdoor air (47.9 +/- 22.8 mu g/m(3)). The 24-hours, average PM10 concentrations at FOS exceeded the EU limit value (50 mu g/m(3)) during 34% of days outdoors and 39% of days indoors. The 24-hours average PM10 concentrations at VK exceeded the limit value during 35% of days outdoors and 53% of days indoors. The 24-hours average PM2.5 concentrations at VK exceeded the WHO daily mean guideline value (25 mu g/m(3)) during 71% of days outdoors and 88% of days indoors. The average PM10 I/O ratio at VK was 1.57 during teaching hours, and 1.00 during no teaching hours. Similarly, average PM2.5 I/O ratio at VK was 1.11 during teaching hours and 0.90 during no teaching hours. Average daily PM2.5/PM10 ratio in the ambient air at VK was 0.87 and 0.82 at FOS. Very strong correlations between the indoor and outdoor PM concentrations were observed at VK during no teaching hours (r gt 0.8). Moderate to strong negative correlations were found between the wind speed and PM at both schools. High outdoor PM concentrations and resuspension of particles are possible reasons for the elevated indoor PM concentrations found in the study. U radu su prikazani rezultati merenja suspendovanih čestica frakcija PM10 i PM2.5 u dve izabrane obrazovne ustanove u Nišu. Kampanje merenja sprovedene su u zimskom periodu. Prva u periodu od 21.02. do 15.04.2010. na Fakultetu zaštite na radu (FOS), a druga u periodu od 20.03. do 04.04.2013. u osnovnoj školi Vožd Karađorđe (VK). Uzorkovanje suspendovanih čestica vršeno je uzorkivačima Sven/Leckel LVS3, simultano, unutar i izvan odabranih ustanova. Prosečna dnevna koncentracija čestica PM10 unutar objekta FOS (47,0±21,8 μg/m3) bila je niža u odnosu na prosečnu dnevnu koncentraciju PM10 u ambijentalnom vazduhu (50,7±28,1 μg/m3). Prosečna dnevna koncentracija čestica PM10 unutar objekta VK (54.6±17.6 μg/m3) bila je viša u odnosu na prosečnu dnevnu koncentraciju PM10 u ambijentalnom vazduhu (47.9±22.8 μg/m3). Srednje dnevne koncentracije čestica PM10 izmerene na lokaciji FOS u ambijentalnom vazduhu prelazile su dnevnu graničnu vrednost (50 ìg/m3) tokom 34% dana trajanja kampanje merenja. Srednje dnevne koncentracije čestica PM10 izmerene unutar objekta FOS prelazile su dnevnu graničnu vrednost tokom 39% dana trajanja kampanje merenja. Srednje dnevne koncentracije čestica PM10 izmerene na lokaciji VK u ambijentalnom vazduhu prelazile su dnevnu graničnu vrednost tokom 35% dana trajanja kampanje merenja, odnosno tokom 53% dana trajanja kampanje u unutrašnjosti objekta VK. Srednje dnevne koncentracije čestica PM2,5 izmerene na lokaciji VK u ambijentalnom vazduhu prelazile su dnevnu graničnu vrednost (25 ìg/m3) tokom 71% dana trajanja kampanje, odnosno tokom 88% dana u unutrašnjosti objekta VK. Prosečan dnevni odnos unutra/spolja čestica frakcije PM10 na lokaciji VK iznosio je 1,57 u vreme nastave, odnosno 1,00 kada nije bilo nastave. Prosečan dnevni odnos unutra/spolja čestica frakcije PM2,5 na lokaciji VK iznosio je 1.11 u vreme nastave, odnosno 0.90 kada nije bilo nastave. Prosečan dnevni odnos PM2,5/PM10 u ambijentalnom vazduhu na lokaciji VK bio je 0,87, odnosno 0,82 na lokaciji FOS. Detektovana je veoma jaka korelacija između koncentracija suspendovanih čestica unutar i izvan objekta VK u periodu kada nije bilo nastave (r gt 0.8). Umerena do jaka korelacija detektovana je između brzine vetra i koncentracija suspendovanih čestica na obe lokacije (FOS i VK). Visoke koncentracije suspendovanih čestica u ambijentalnom vazduhu i resuspenzija čestica najverovatniji su razlog koji utiče na povećane koncentracije suspendovanih čestica u unutrašnjem prostoru posmatranih obrazovnih ustanova.

Ovaj rad predstavlja metodu kojom se ispravljaju učinci deformacije ispitnog modela zbog aerodinamičkih opterećenja u transoničkom vjetrenom tunelu. Deformacija za superkritični ispitni model krila mjerena je pod utjecajem dinamičkog tlaka u European Transonic Wind tunelu (ETW) pomoću Stereo Pattern Tracking (SPT) sustava (sustava za stereo praćenje uzoraka). Deformirana mreža modela stvorena je tehnologijom deformacije strukturnih rešetaka razvijenom u ovom radu, a numerički rezultati krutih i deformiranih modela postignuti su na osnovi RANS-a (Reynolds-averaged Navier-Stokes solver). Zatim je ispravljena deformacija modela dobivena oduzimanjem računalnih uzdužnih aerodinamičkih koeficijenata originalnog modela od onih deformiranog. Rezultati su pokazali da je postignuta dobra korelacija eksperimentalnih i numeričkih rezultata deformiranog modela, potvrđujući pouzdanost numeričke metode koja je razvijena kako bi se simulirala deformacija modela. Također se predlaže da se metoda razvijena u ovom radu može upotrijebiti za korekciju deformacije testnog modela za izvorne podatke vjetrenog tunela., This paper presents a method to correct test model deformation effects due to aerodynamic loads in transonic wind tunnel. Deformation for a supercritical wing test model was measured under variation of dynamic pressure in the European Transonic Wind tunnel (ETW) using the Stereo Pattern Tracking (SPT) system. Deformed model mesh was generated by the structure grids deformation technology developed in this paper, and numerical results of rigid and deformed models were achieved based on the RANS solver. Then, correction of model deformation was obtained by subtracting the computational longitudinal aerodynamic coefficients of original model from those of deformed one. Results indicated that a good correlation of experimental and numerical results of deformed model was achieved, validating the reliability of numerical method developed to simulate model deformation. It is also suggested that the method developed in this paper could be used to correct test model deformation for original wind tunnel data.

Cilj ovog rada je proučavanje hidroloških odnosa dvaju susjednih krških izvora Jadro i Žrnovnica u Hrvatskoj. Rad se fokusira na utvrđivanju utjecaja temperature, relativne vlažnosti, oborina i protoka na ponašanje i odnose dvaju izvora. Parcijalna korelacijska analiza vremenskih serija implicira da utjecaj kontrolne vremenske serije na kroskorelacijsku funkciju između ulazne i izlazne vremenske serije može biti detektiran pomoću korelacijskog koeficijenta između ulazne i kontrolne vremenske serije, i kroskorelacijske funkcije između kontrolne i izlazne vremenske serije. Napajanje podzemnih voda ovisi o procesu evapotranspiracije i oborinama, dakle temperatura zraka, relativna vlažnost i oborine kontroliraju prostornu i vremensku distribuciju ovih procesa. Najveći doprinos ovog rada leži u korištenju obične korelacije i parcijalne korelacijske analize prvog reda za karakterizaciju funkcioniranja i odnosa dvaju susjednih krških izvora u sušnoj i kišnoj hidrološkoj godini koristeći satne podatke. Dokazano je da je u slučaju susjednih krških izvora protok svakog pojedinog izvora ima utjecaj na korelaciju oborineprotok drugog izvora. Demonstrirani pristup predstavlja poboljšanje u analizi odnosa susjednih krških izvora u sušnim i kišnim periodima, i može se primijeniti na bilo koje susjedne krške izvore. The objective of this work is the study of two adjacent karst springs Jadro and Žrnovnica in Croatia. This work focuses on the effects of temperature, relative humidity, rainfall and discharges on the behaviour and relations of two adjacent karst springs. Partial correlation analysis implies that the impact of the control signal on the cross-correlation function between the input and output signal can be detected from the correlation coefficient between the input signal and control signal and from the cross-correlation function between the control signal and output signal. The groundwater recharge depends on the process of evapotranspiration and rainfall, so air temperature, relative humidity and rainfall control the spatial and temporal distribution of this process. The major contribution of the paper relies on the utilization of simple correlation and fist-order partial correlation analysis to characterize the functioning and relations of two adjacent karst springs in a dry and wet hydrological year by using hourly data. It has been confirmed that in the case of adjacent karst springs the discharge of each spring has effect on the rainfall-discharge correlation of the other spring. The demonstrated approach represents an improvement in investigating the relations of adjacent karst springs in dry and wet periods, and can be applied on any adjacent karst springs.

Rad se odnosi na određivanje regresijskog modela odnosa ekonomskih i ekoloških karakteristika materijala kod odabira u graditeljstvu. Kako bi se do toga uopće došlo, prethode neka od teorija, razjašnjenja. Rad je podijeljen u više dijelova. U prvom dijelu biti će riječi o statistici, točnije njezinom dijelu – korelaciji i regresiji. Njezino značenje, upotreba, odnosi, rješenja i analize. U današnjici, mnogo se pažnje posvećuje pretpostavkama, nagađanjima stoga su spomenute analize od velike koristi u današnjem društvu te poslovanju. Kako bismo započeli teoriju te sam konačni dolazak do modela regresije, potrebno je informirati se o čemu će biti riječi. U ovom radu to su građevinski materijali. Stoga je drugi dio posvećen teoriji građevnog materijala. Odrađeni su neki od osnovnih materijala – drvo, metali, polimerni materijali, beton. Naglasak je na osnovnim sirovinama svakog od materijala, tehnološkom procesu proizvodnje, fizikalno-mehaničkim svojstvima, vrstama materijala te na njihovoj upotrebi. Neke od vrijednosti su prikazane tablično radi lakše usporedbe. Nakon razrade svakog od materijala, navedene su ekološke prednosti materijala i njihov utjecaj na okoliš. Razradivši dio teorije, u tablici su prikazani konačni materijali i njihove cijene te korištenje. Korištenjem koeficijenta korelacije određena je mjera povezanosti ovih varijabli. Nakon određivanja jačine korelacije razvijen je regresijski model. This paper refesrs to determination of the regression model of relationship between economic and ecological characteristics of building materials. To achieve this precede theories and research. The work is divided into several parts. In the first part there will be words about statistics, more precisely the part – correlation and regression. It implies meaning, usage, relationships, solutions and analysis. Today, a lot of attention is paid to the assumptions and speculations, so these analyses are great benefit in today's society and business. In order to begin the theory and final arrival till regression modul it's necessary to inform what the word will be. In this case they are building materials. So the second part is devoted to the theory of building materials. Some of the basic materials – wood, metals, polymer materials, concrete – have been processed. The emphasis is on the basic raw materials of each material, the technological process od production, the physical-mechanical properties, the types of materials and their use. Some of the values are shown in a table for easier comparison. After the elaboration of each material, the environmental benefits of the material and their environmental impact are listed. By elaborating part of the theory, the table shows the final materials and their prices and use. Using the coefficient of correlation, the correlation measure of these variables has determined. After determining correlation strenght, a regression model was developed.

This paper provides the theoretical and empirical analysis of unjustifiably neglected topic byour researchers, but at the same time exceptionally current problem of correlation and teamwork in the class as elementary prepositions for reaching holism in learning and teaching.Through emphasizing holistic approach intersected with contemporary constructivist notion ofteaching process, this paper analyses importance, types, contributions, and requirements andbasic presumptions for quality conducting correlation and team work in the class. Empiricalanalysis of elementary and secondary school teachers’ opinions (group of examinees from 10urban and rural schools in County of Zadar: 5 elementary + 5 secondary schools; N = 106)includes establishing manifesting forms of correlations in the teaching practice and determiningits frequency, establishing adequacy and sufficiency of teaching competences for deductingcorrelations constructed within different educational/learning contexts (formal, non-formal,informal) along with the analysing correlations’ contribution to the quality of teaching, as wellas teachers’ suggestions about possible ways of improving its implementation. Furthermore, thispaper defines the frequency of carrying out team work in the class, the initiators of its planningand realization, practical contributions of that kind of work and teachers’ suggestions aboutits possible improvement. Based on the indicators of the basic descriptive statistics, the data iscomparatively analysed and additionally commented, and with the qualitative analysis of thedata from teachers’ opinions about the contribution and possible ways of improving constructingcorrelations and team work, the rounded picture of examined problematic is procured. Thereby,this paper represents theoretical and empirical contribution to the research of holistic approachto teaching process through constructing correlations and team work in the class. Even thoughteachers are aware of their multiple positive contributions to the teaching quality, the resultshave shown insufficient representation of those kinds of work in the teaching practice, as well aspossible causes of that state: insufficient and inadequate teachers’ qualifications, non-stimulatingenvironment, insufficient cooperation among teachers, inadequacy of current teaching lessonplans and programs and schools’ curriculums, along with the school architecture and time-tables.Acknowledging teachers’ suggestions could contribute to surpassing existing obstacles and to theimprovement of constructing correlation and team work in the class as means of special valueand roads to integrative, holistic learning and teaching.

Kukuruz (Zea Mays L.) je jednogodišnja, kulturna biljka. Zbog razdvojenosti generativnih organa i različitog vremena sazrijevanja muških i ženskih cvjetova na istoj biljci, kukuruz je izrazito stranooplodna biljka. Inbred linije su homozigotne oplemenjivačke linije koje se upotrebljavaju kao roditelji hibridnih kultivara u stranooplodnim vrstama. Takve linije nastaju samooplodnjom, križanjem u srodstvu, povratnim križanjem ili metodom dihaploida. Budući da se homozigotnost najlakše postiže samooplodnjom, upravo se taj postupak najčešće koristi u razvoju inbred linija. Sorte stranooplodnih biljnih vrsta moraju proći postupak samooplodnje kako bi se kod potomstva smanjila heterozigotnost i stvorio određen broj različitih homozigotnih linija. Križanje inbred linija, ovisno o broju roditelja, može biti dvojno, trojno, četverolinijsko ili povratno. Najčešća metoda razvoja novih linija samooplodnog bilja je pedigre metoda, te se ista koristi i kod stranooplodnog bilja. Linije razvijene metodom pedigrea su homozigotne i homogene, ali s novim genskim kombinacijama. Postupak započinje nakon odabira pojedinačnih biljaka koje se križaju da se dobije F1 generacija, koja je genotipski i fenotipski uniformna i u njoj nema izbora. Nakon samooplodnje biljaka F1 generacije obrano sjeme se sije i uzgaja u F2 generaciji, te se postupak ponavlja dok se u jednom redu ne postigne uniformnost biljaka; to je obično u F5 – F7 generaciji. U istraživanju provedenom tijekom 2008. godini prikupljeni su podatci o svojstvima F3 potomstva četiri kombinacije križanja inbred linija. Korištene su deskriptivne statističke metode radi procjene varijabilnosti analiziranih svojstava (duljina klipa, promjer klipa, masa klipa, broj redova na klipu) za potomstva pojedinih kombinacija križanja. Analizom varijabilnosti i korelacije, utvrđene su značajne razlike u odstupanjima i povezanosti pojedinih svojstava, unutar i između kombinacija križanja. Razlike između potomstava, koje su se pokazale značajno signifikantne, različitih kombinacija križanja za sva analizirana svojstva istražene su uz pomoć analize varijance. Corn (Zea Mays L.) is annual, cultivated plant. Due to separation of generative organs, and the different time of maturing of male and female flowers on the same plant, corn is very open pollinated plant. Inbred lines are homozygous breeding lines that are used as parents of hybrid cultivars in open fertilized species. Such lines are formed by self-fertilization, inbreeding, backcrossing or by dihaploid method. Since homozygosity is best achieved by self-fertilization, this procedure is most often used in the development of an inbred line. Varieties of open fertilized plant species must undergo self-fertilization to reduce heterozygosity in the progeny and to create a certain number of different homozygous lines. The crossing of inbred lines, depending on the number of parents, can be single cross, triple cross, double cross or backcross. The most common method of developing new lines of self-fertilizing plants is the pedigree method, and the same is used in the open fertilized plants. The lines developed by the pedigree method are homozygous and homogeneous, but with new gene combinations. The procedure begins after the selection of individual plants for crossing to obtain F1 generation, which is genotypically and phenotypically uniform and there is no choice in it. After self-fertilization of the F1 generation plants, the skimmed seed is sown and grown in the F2 generation, and the procedure is repeated until in one line is achieved plant uniformity; this is usually in the F5 - F7 generation. In a study conducted during 2008, the data of the F3 progeny properties were collected. Descriptive statistical methods were used to estimate the variability of the analyzed properties (piston length, piston diameter, piston mass, number of piston rows) for the progeny of certain hybridization combinations. By analysis of variability and correlation, significant differences were found in the deviations and correlations of certain properties, both within and between the crossing combinations. The differences between the progeny, which proved to be significantly significant, of different combinations of crossings for all analyzed properties were examined with the help of analysis of variance.

Burze su platforme za trgovanje vrijednosnim papirima poput dionica i obveznica.

The graphical representation of the correlation between the stock price and the CROBEX index is shown in the Shiny application. Used technologies are: R, RStudio Shiny and MySQL databases.

Grupiranje je jedna od najčešćih metoda analize podataka. Spektralno grupiranje je relativno nova metoda koja je posljednjih 10-20 godina dosta istraživana. Metoda spektralnog grupiranja zahtijeva da se podatci koje je potrebno grupirati prikažu u formi neusmjerenog grafa u kojem se težine bridova definiraju kao mjere sličnosti između podataka. Glavni alat za spektralno grupiranje je matrica Laplacijan grafa koja se dobiva iz matrice sličnosti i matrice težina. Matrica sličnosti se dobije pomoću funkcija korelacije i Gaussove funkcije. Iz te Laplacijanove matrice se dobivaju svojstveni vektori. Na kraju se metodom k-meansa dobiju klasteri iz matrice stupnjeva i matrice svojstvenih vektora. Dobivena funkcija je prvo testirana na simuliranim podacima kojima se unaprijed znao rezultat grupiranja te se na taj način potvrdila njena ispravnost. Nakon toga se funkcija primijenila na vremenskim podacima koji su bili prihodi 9 sektora s američkog tržišta. Ulaganje u tako grupirane sektore je rezultiralo isplativije od indeksa S&P500 po pitanju prihoda i preuzetog rizika. Clustering is one of the most common methods of data analysis. Spectral Clustering is relatively new clustering method which has become popular in recent years. For the purpose of clustering the given objects (people, pixels, points...), we represented the data in a form of a weighted undirected graph where the nodes are the points in a feature space and the edges represent similarities between the points. The most important part of this clustering method is finding Laplacian matrix that is derived from the similarity matrix and weight matrix. The similarity matrix is obtained by the correlation function and the Gauss function. From these Laplacian matrices, native vectors are obtained. Finally, k-mean method gets clusters from the matrix of degrees and the matrix of the eigenvectors. The obtained function was first tested on simulated data to pre-know the result of the grouping and thus confirmed that the function is valid. After that, the function was applied to time series data which were 9 sectors revenue from the US market. Investments in such grouped sectors have resulted to be more profitable than the S&P500 index based on sector revenue and risk taken.

U ovom radu predstavljena je metoda lokalizacije zasnovana na slaganju uzastopnih očitanja laserskog senzora udaljenosti. Ova metoda uspoređuje referentni i trenutni položaj robota, na način da u svakom trenu računa promjenu kuta, te x i y koordinate. Ukupni položaj predstavlja ukupni zbroj promjena. Učinkovitost ove metode promatrana je u RViz vizualizatoru, te su rezultati predstavljeni u Matlabu. Pokazano je da lokalizacija na temelju metode slaganja uzastopnih laserskih očitanja daje dobre rezultate za određene situacije. No, ipak određeni nedostatci su vidljivi pa je nadogradnja ove metode potrebna. This paper presents scan matching method based on the consecutive scan matching readings of laser range finder. This method compares reference and current position of robot by calculating change of angle and x and y axis in every moment. Final position is sum of these changes. Effectiveness of the method was observed in RViz and results were presented in Matlab. It is shown that localization based on the consecutive scan matching readings of laser range finder gives good results for some situations. But, some disadvantages are visible so this method needs updating.
