BACKGROUND The main export varieties in China are brand-name, high-quality bred aquatic products. Among them, tilapia has become the most important and fast-growing species since extensive consumer markets in North America and Europe have evolved as a result of commodity prices, year-round availability and quality of fresh and frozen products. As the largest tilapia farming country, China has over one-third of its tilapia production devoted to further processing and meeting foreign market demand. RESULTS Using by tilapia fillet processing, this paper introduces the efforts for developing and evaluating ITS-TF: an intelligent traceability system integrated with statistical process control (SPC) and fault tree analysis (FTA). Observations, literature review and expert questionnaires were used for system requirement and knowledge acquisition; scenario simulation was applied to evaluate and validate ITS-TF performance. CONCLUSION The results show that traceability requirement is evolved from a firefighting model to a proactive model for enhancing process management capacity for food safety; ITS-TF transforms itself as an intelligent system to provide functions on early warnings and process management by integrated SPC and FTA. The valuable suggestion that automatic data acquisition and communication technology should be integrated into ITS-TF was achieved for further system optimization, perfection and performance improvement. © 2014 Society of Chemical Industry

Temperature monitoring, shelf-life visibility and Least Shelf-life First Out (LSFO) stock strategy are important contents in perishable food cold chain logistics for both cold chain managers and workers in order to reduce quality and economic losses. This paper illustrates a wireless sensor network (WSN) based integrated Cold Chain Shelf Life Decision Support System (C2SLDS) designed for perishable food product cold chain management. The system is implemented based on the WSN and time temperature indicator (TTI) features. Compared with traditional cold chain management methods used before, the C2SLDS not only bridges the information gap which exists between different cold chain phase enterprises and provide a seamless information flow along the whole chain but also enables cold chain enterprises to predict perishable food's shelf-life and helps make a smart LSFO strategy to reduce the quality and economic loss. System test and evaluation shows that the infield radio transmission is reliable and the whole system meets most of the users' requirements raised in system analysis.

Logistics processes of perishable food in the supply chain include the distribution activities and the real time temperature monitoring to fulfil the cold chain requirements. The paper presents the use of RFID (Radio Frequency Identification) technology as an identification tool of receiving and shipping activities in the cold store. At the same time, the use of RFID data loggers with temperature sensors is presented to observe and store the temperatures for the purpose of analyzing the processes and having the history data available for traceability purposes and efficient recall management., {"references":["C.

Uporaba interneta je vse bolj razširjena na različnih področjih in za različne namene. Spletne aplikacije so vse bolj napredne in ponujajo različne uporabniške izkušnje. V ta namen se o uporabniku shranjujejo podatki, ki so lahko samo neškodljivi piškotki, lahko pa so tudi osebni podatki. Na številnih spletnih mestih zahtevajo prijavo z uporabniškim imenom in geslom, do katerih bi lahko dobili dostop zlonamerni ljudje in z njimi škodovali spletnim uporabnikom za svoj dobiček. V diplomskem delu je predstavljena spletna varnost, oziroma njene pomanjkljivosti. Predstavili smo petnajst različnih zlonamernih ranljivosti po priporočilih OWASP, nato pa smo jih analizirali na spletni aplikaciji NOVA Portal. Ta je namenjena pregledu in kreiranju ponudb ter pogodb za predstavnike in stranke lizing financiranja. Za vsak napad je opisano delovanje in njegov vpliv na spletni aplikaciji NOVA Portal. V primeru odkritih varnostnih tveganj je zapisana tudi ustrezna rešitev za odpravo teh. Ob ustreznem upoštevanju rešitev je mogoče izboljšati spletno varnost. The use of the internet is widespread in various fields and for various purposes. Web applications are increasingly advanced and offer many better user experiences. For this purpose the user data is stored in various forms. There are implemented only harmless cookies or the personal data is stored. Many websites require login with a username and password, which malicious people could gain access to and use to harm online users for their own profit. The thesis presents the web application security and fifteen critical vulnerabilities from OWASP recomendations. Afterwards, they are applied on the NOVA Portal application, which is intended for review and creation of offers and contracts for representatives and customers of leasing financing. For each attack, the operation and its impact are described on the NOVA Portal web application. In case of discovered security risks, it was also written down the appropriate solution for its elimination. With proper consideration of solutions, online security can be improved.

V diplomski nalogi je predstavljen prototip avtonomnega avtomatiziranega ksilofona, ki ima možnost nalaganja in igranja datotek MIDI in možnost igranja akordov. Uporabljen je kromatični ksilofon, ki zaradi dodanih poltonov omogoča večjo izbiro skladb. Avtonomnost je zagotovljena z uporabo dveh mikrokrminlnikov Arduino Uno, modula Bluetooth HC-05 za sprejemanje in posredovanje podatkov in mobilne aplikacije Xylo Boss preko katere je možno avtomatiziran ksilofon kontrolirati brezžično. Nalaganje in igranje datotek MIDI je omogočeno z lastno razvito knjižnico in s pomožno knjižnico za prevajanje podatkov, ki so uporabljeni za avtomatiziran ksilofon. Za igranje akordov pa smo si pomagali z rešitvijo, ki je zapisana v dokumentaciji standarda MIDI - v primeru akorda se med notami izvede krajša zakasnitev, ki je človeško uho ne zazna in nam zato da občutek, da je bil zaigran akord. V procesu izdelovanja avtomatiziranega ksilofona so bili narejeni: ogrodje za ksilofon, robotske ročice, stojala za robotske ročice, držalo za tiskano vezje, skica vezja, načrt za tiskano vezje, tiskano vezje, konektor za povezavo napajalne baterije z mikrokrmilnikoma, pomožne knjižnice za lažje programiranje in nazadnje še aplikacija za krmiljenje avtomatiziranega ksilofona. This thesis presents a prototype of an autonomous automated xylophone, which has the ability to load and play MIDI files and the ability of playing chords. A chromatic xylophone is used, as it includes half tones, which add a greater selection of playable songs. The autonomous solution is the use of two Arduino Uno microcontrollers, a Bluetooth module HC-05 for receiving and sending data and a mobile application Xylo Boss for controlling the automated xylophone wirelessly. Reading and playing the MIDI files was solved with a new specialy developed and an additional library for translating received data to those understood by the automated xylophone. The solution for playing chords was taken from a solution given in the documentation of MIDI standard - in case of a chord there is a shorter delay, which can't be detected by a human ear, giving us an illusion that a chord was played. Other things created in the developing process of an automated xylophone were: a xylophone frame, robotic hands, stands for the robotic hands, a holder for the printed circuit board, a circuit sketch, a circuit blueprint for a printed circuit board, a printed circuit board, additional libraries to make programming easier and a mobile application for controlling the automated xylophone.

Upravljanje identitet in nadzora dostopa sta ključni komponenti spletnih aplikacij, ki zahtevajo preverjanje pristnosti končnih uporabnikov. V ta namen se v številnih rešitvah uporabljajo standardizirani protokoli, kot sta protokola OpenID Connect in OAuth 2.0. V odprtokodnem sistemu Keycloak, ki je namenjen upravljanju identitet in nadzora dostopa, so razvijalcu v pomoč njegove številne funkcionalnosti in komponente. Za prikaz njegove vpeljave v aplikacijo je razvita testna spletna aplikacija v javanskem programskem okolju Quarkus, na temo spletne knjigarne. Za prikaz delovanja aplikacije so narejene končne točke z različnimi metodami zahtev. Z njimi je prikazano delovanje sistema na podlagi vlog in atributov, na različnih primerih uporabe. Identity management and access control are key components of web applications that require end-user authentication. For this purpose, many solutions use standardized protocols such as the OpenID Connect and OAuth 2.0. One such solution is Keycloak, an open source identity management and access control system, that offers developers many functionalities and components. To demonstrate its implementation in the application, a test web application is developed in Java using the Quarkus framework, on the topic of an online bookstore. Endpoints are made using different request methods to demonstrate the application's performance. They are used to show the operation of the system based on roles and attributes, on different use cases.

Cilj diplomske naloge je bil ustvariti spletno aplikacijo, ki bo uporabniku omogočala spremljanje nakupov živil in njihovo porabo. S tem namenom smo naredili aplikacijo, ki uporabniku omogoča beleženje živil, ki jih ima v hladilniku in zamrzovalniku. Poleg vnosa živil je uporabniku na voljo izračun roka uporabe za sveža živila, pomoč pri načrtovanju naslednjega nakupa z nakupovalnim seznamom in pregledom v preteklem času porabljenih in zavrženih živil, ter opozarjanje na iztek roka uporabe. Aplikacija je razvita v okolju Node.js, razdeljena na čelni del izdelan z react.js, zaledni sistem napisan v jeziku TypeScript in podatkovno bazo postgreSQL. Zaledni in čelni sistem komunicirata preko storitev REST API in si tako izmenjujeta podatke. Zaledni sistem poskrbi da so vsi podatki pravilno shranjeni v bazi. The aim of the diploma thesis was to create a web application that will allow the user to monitor the purchase of food and its consumption. With that in mind, we have created an application that allows the user to record the food he has in the refrigerator and freezer. In addition to food entry, the user has the option of calculating the expiration date for fresh food, assistance in planning the next purchase with a shopping list and a review of consumed and discarded food in retrospect, and reminder of the expiration date. The application is made in the Node.js environment, it is divided into a front-end development with react.js, a back-end system written in the TypeScript language and a postgreSql database. The back-end and front-end systems communicate via the REST API service and thus exchange data. The back-end system ensures that all data is stored correctly in the database.

Asane oz. položaji imajo v jogi velik pomen, zato je pomembno, da je izvajanje le-teh pravilno in v skladu z zmožnostmi posameznika. Prav z namenom učenja pravilne izvedbe položajev, spremljanjem napredka in sledenja lastnim občutkom smo razvili mobilno aplikacijo Asana Master. Primerna je tako za začetne kot nadaljevalne praktikante, saj so Asane razdeljene na različne stopnje, prav tako pa si praktikant lahko sam določi svoje cilje, ki jim sledi, objavi sliko napredka in ustvarja zapiske oz. dnevnik občutkov. Aplikacija je razvita z uporabo ogrodja React Native in odprtokodno platformo Expo. Deluje na operacijskem sistemu Android in je povezana preko aplikacijskega programskega vmesnika z reprezentativnim prenosom stanj (textit{ang. REST API)} s strežnikom podatkovnega nivoja. Asanas are of great importance in yoga, so it is important that their implementation is correct and in accordance with the abilities of the individual. In order to learn the correct execution of asanas, we developed the Asana Master mobile application for easy learning and tracking the progress. It is suitable for both beginners and advanced practitioners, as the Asanas are divided into different stages, and the practitioner can also determine his own goal which he can follow and improve, upload a picture of progress and write notes to track his feelings. The application was developed using the React Native framework and the open-source Expo platform. It runs on Android operating system and is connected via a REST API to a data server.

Senzorski podatki, ki so merjeni ob različnih časovnih intervalih, se lahko prikažejo na različne načine, pri tem pa je ljudem najbljižji grafični prikaz. Diplomska naloga zajema načrtovanje in izdelavo spletne aplikacije za uvoz obstoječih podatkov v lastno podatkovno bazo ter vizualizacijo podatkov v obliki tabele, črtnega grafikona in stolpičnega diagrama. Uvoz podatkov je mogoč na tri različne načine: ročni uvoz z dodatnim vnosom metapodatkov za podane meritve, ki zahteva nekoliko več uporabniške interakcije uvoz iz datoteke brez dodatne interakcije uporabnika ter uvoz iz oddaljene storitve Google Drive, ki omogoča pridobivanje podatkov iz drugih obstoječih sistemov. Spletna aplikacija je razvita v programskem jeziku PHP in ogrodju Laravel, pri gradnji uporabniškega vmesnika pa sta uporabljeni ogrodji Vue.js in Tailwind. Vizualizacija podatkov je urejena s pomočjo knjižnice za vizualiziranje Amcharts. Ob prikazanih podatkih je uporabniku na voljo tudi izvoz v obliki slike ali datoteke .csv. Sensory data measured at different time intervals can be displayed in different ways, however, presenting it in a graphical representation has been found to be the easiest to understand by many users. This diploma thesis includes the planning and development of a web application for the import of existing data into its own database, and the visualization of data in the form of a table, line chart, and column chart. Data import is possible in three different ways: manual import with additional metadata entry for given measurements, which requires slightly more user interaction import from file without additional user interaction and import from a remote service Google Drive that allows retrieval of data from other existing systems. The web application is developed in the PHP programming language and the Laravel framework. The user interface is developed with Vue.js and Tailwind frameworks. Data visualization is arranged using the Amcharts visualization library. In addition to a display, the user can also export data in the form of an image or .csv file.

Z vsesplošno uporabo naprednih tehnologij se je pojavila potreba po varovanju elektronsko shranjenih osebnih podatkov. Zato je bila v letu 2018 sprejeta Splošna uredba o varstvu podatkov (SUVP), ki dopolnjuje Zakon o varstvu osebnih podatkov (ZVOP-1) in se osredotoča predvsem na elektronsko zbiranje in obdelovanje podatkov. Organizacije morajo zato zagotoviti ustrezen način shranjevanja in urejanja podatkov. Zakon o prostovoljstvu je bil sprejet leta 2011, ureja pravice in dolžnosti prostovoljca in dolžnosti, ki jih ima organizacija do prostovoljca. Zaradi sprememb v zakonodaji se je pojavila potreba po posodobitvi baze članstva društva tabornikov Rod Tršati Tur. Namen diplomske naloge je predstavitev zakonodaje, povezane z društvi, prostovoljstvom ter varovanjem osebnih podatkov in izdelava spletnih aplikacij baze članstva ter lokostrelskega tekmovanja. Diplomska naloga je razdeljena na teoretični in praktični del. Prvi del obsega predstavitev zakona o društvih (ZDru-1), organiziranosti taborniških organizacij in zakona o prostovoljstvu (ZProst). Praktični del obsega razvoj spletne aplikacije lokostrelskega tekmovanja in spletne aplikacije baze članstva. Spletna aplikacija lokostrelskega tekmovanja omogoča elektronsko izvedbo tekmovanja in prijav. Spletna aplikacija baze članstva je razvita v skladu s SUVP in omogoča dodajanje in urejanje članov v društvu. Izdelani sta v ogrodju Laravel in v programskih jezikih PHP in JavaScript. Spletno aplikacijo baze članstva je mogoče z nekaterimi spremembami uporabiti v katerikoli taborniški ali prostovoljski organizaciji. With the widespread use of advanced technologies, the need has arisen to protect electronically stored personal data. Therefore, in 2018, the General Data Protection Regulation (GDPR) was adopted, which supplements the Personal Data Protection Act (ZVOP-1) and focuses mainly on electronic data collection and processing. Organizations must therefore ensure that data is stored and edited appropriately. The Volunteering Act, passed in 2011, regulates the rights and duties of a volunteer and the duties that an organization has towards a volunteer. Due to changes in legislation, there was a need to update the membership base of the Scout Association Rod Tršati Tur. The purpose of the diploma thesis is to present the legislation related to associations, volunteering and personal data protection and to create web applications for the membership database and archery competitions. The diploma thesis is divided into theoretical and practical part. The first part includes a presentation of the Associations Act (ZDru-1), the organization of scout organizations and the Volunteering Act (ZProst). The practical part includes the development of the online application of archery competition and the online application of the membership database. The online application of archery competition enables the electronic execution of competitions and entries. The web application of the membership database is developed in accordance with the SUVP and enables the addition and editing of members in the association. They are made in the Laravel framework and in the programming languages PHP and JavaScript. The online membership database application can be used with any changes in any scout or volunteer organization.

Krmilni sistem je bil razvit za izvajanje dodatnega nadzora nad kakovostjo delovanja stroja za razrez in odstranjevanja izolacije iz koaksialnih kablov med proizvodnim procesom. Poleg nadzora je zasnovan enoten sistem za komunikacijo s tiskalno napravo, ki kable med rezanjem tudi označuje. Diplomsko delo predstavlja proces načrtovanja in izdelave samostojne naprave, ki je vključena v proizvodnjo kablov. Krmilno vezje z mikrokrmilnikom AtMega328p-au sprejema podatke iz inkrementalnega rotacijskega kodirnika, ki je prislonjen na kabel v proizvodni liniji. Hkrati lahko nadzoruje tiskalno napravo, ki kable v procesu izdelave potiska s primerno oznako. Vezje je zasnovano kot razširitvena plošča (angl. Shield) za mikroračunalnik Raspberry Pi. Programska oprema je zasnovana tako, da se lahko operater preko grafičnega vmesnika na zaslonu na dotik identificira ter nastavi parametre za tisk in nadzor rezanja kabla. The system was designed to lead a separate quality control alongside the production line which cuts and removes insulation from coaxial cables. It offers additional functionality to optimize the printing process that marks cables. The work explains the process of designing a system, which combines custom-designed firmware and software that solves the issue of separate control and optimizes printing. Custom designed PCB with the main microcontroller AtMega328p-au reads data from an incremental rotary encoder attached to the cable in the production line. The controller communicates with the printing machine that prints the labels during manufacturing. PCB is designed like a shield for the Raspberry Pi computer. The touch screen displays a graphical user interface for identification of operators which will assign parameters for printing and quality control for cutting cables.

V diplomski nalogi smo zasnovali in izdelali prototipni sistem, ki ga sestavljata senzorski modul in Android aplikacija E-nose. Na mikrokrmilnik Arduino Nano so povezani senzor za temperaturo in vlago DHT22 ter plinski senzorji MQ-3, MQ-135, MQ-136, MQ-138, ki omogočajo enostavno spremljanje zorenja sadja in ugotavljanje svežine živil. Za nadzor delovanja, zajem, shranjevanje in prikaz meritev skrbi Android aplikacija E-nose, ki na mobilni napravi komunicira s senzorskim modulom preko 'bluetooth' povezave. Meritve so predstavljene z grafi tako med izvajanjem meritev, kakor tudi po zaključenem poskusu. Omogočen je tudi izvoz podatkov v datoteki .csv. Delovanje elektronskega nosu smo preverili z analizo zorenja marelic in nektarin. V različnih temperaturnih pogojih, kot sta soba in hladilnik, smo jih testirali deset dni. Pridobili smo zanimive rezultate, ki prikazujejo zaznavanje lažje hlapnih spojin, med katerimi je najpomembnejši alkohol. Electronic nose is one of useful solutions for measuring food quality, which is usually done by trained people using smell. In this thesis we designed and created a prototype system consisting of a sensor module and Android application named E-nose. The Arduino Nano is connected to a sensor for temperature and humidity DHT22 and gas sensors MQ-3, MQ-135, MQ-136 and MQ-138 that allow easy monitoring of fruit ripening and the freshness of food. For capturing, saving and displaying data is used Android application E-nose, that communicates with the sensor module over bluetooth. While capturing data is displayed on a live chart and later on when capture is completed on a static chart. It is also possible to export data in .CSV file. The electronic nose was tested by making experiments on apricots and nectarines that were stored at different temperatures for ten days. We got interesting results for the gasses from which the most concentrated was alcohol.

V spletnih aplikacijah prihaja do neustreznih prevodov zaradi slabega vpogleda v končni rezultat zapisov, ki jih je uredil prevajalec. Prevajalec prejme datoteko z vsebinami, ki se nahajajo na spletni strani. Ko vsebino prevede iz obstoječega v zahtevani jezik, jo posreduje razvijalcu, ki jo nato vključi v spletno aplikacijo. Spletno stran nato pregleda in preveri ali so pravilni prevodi, dolžine in oblike tekstov. Pogosto pride do napak v prevodih, ali pa so prevodi predolgi in je potrebno preoblikovati besedilo. V tem primeru se postopek prevajanja ponovi. V okviru diplomskega dela smo razvili knjižnico, ki prevajalcem omogoča sproten pregled vsebin v zahtevanem jeziku. Preizkusili smo jo na spletni aplikaciji Apollo. Sestavljena je iz predstavitvenega dela in iz aplikacije, ki je izdelana v ogrodju Angular. Knjižnica omogoča prevajanje besedila v brskalniku testne verzije. S klikom na zapis, ki se pretvori v vnosno polje za urejanje, je omogočen vpis prevoda. Po končanem prevajanju določenega besedila prevajalec klikne izven polja besedila ter tako shrani prevod v lokalno shrambo. Ko zaključi s prevajanjem, lahko datoteko z vsemi prevodi v formatu JSON posreduje razvijalcem, ki jo nato vključijo v aplikacijo in omogočijo prikazovanje novih prevodov na spletni strani. Knjižnica izboljša in pospeši delo prevajalcev, ker lahko v brskalniku sproti pregledujejo izgled in prevedene vsebine. While developing web applications, inadequate translations are provided due to poor overview of the final records provided by the translator. The translator receives a file with contents located on the web pages. When the file of records is translated into the required language, it is submitted to the developer, who then adds translations to the web application. The web page is after that checked for correct translations, the structure and style of the page. Often, bad translations occur, the records are too short, or even too long. In that case, the translation process needs to be repeated. As a part of our thesis, we developed a library, that allows translators to see up-to-date review. The library was tested on the Apollo, invoicing web application. The solution consists of the presentation part and the web application part developed with an Angular framework. The library makes the record on the website translatable in the browser of the test environment. By clicking on the record, it is converted to an input field, where the text can be edited. After that, the translation is saved in the local storage. It can be downloaded in the JSON file format and sent to developer, who adds the file to the web application. The library improves and speeds up the work of translators by enabling them to see the full review of translated web page.

V današnjem svetu igrajo podatki zelo pomembno vlogo v nadzoru hladne verige hitro pokvarljivih živil. Običajno prihajajo iz različnih senzorskih sistemov in v različnih podatkovnih formatih, pogosto pa se zbirajo in shranjujejo tudi v datotekah. Za takšen primer smo razvili spletno aplikacijo, ki omogoča enostaven vnos, shranjevanje, analizo in vizualizacijo celotnega postopka zajema senzorskih meritev. Omogočeno je dodajanje in urejanje parametrov, ki so povezani z meritvami. Na podlagi vnaprej definiranih zahtev o ravnanju z živili v hladni verigi in z analizo meritev se izračuna preostala doba uporabnosti, ki je prikazana v časovnem grafu. V aplikaciji so nazorno prikazane tudi morebitne anomalije v podatkih. V diplomski nalogi je opisan postopek izdelave spletne aplikacije, ki smo jo razvijali z ogrodjem Laravel in podatkovno bazo MySQL. Grafični vmesnik je prilagojen za vse vrste naprav, za potrebe lažjega testiranja je bil dodan tudi generator podatkov, ki omogoča dodatne analize simuliranih dogodkov v hladni verigi. Vključeno je dodeljevanje in urejanje pravic uporabnikov. Na koncu smo spletno aplikacijo testirali z realnimi meritvami hladne verige. In today's world, data plays a very important role in the cold chain control of perishable food products. Data usually comes from various sensor systems and in different data formats, often collected and stored in files. This is why we have developed an web application that allows easy entry, storage, analysis and visualization of the whole process covering the sensor measurements. It is possible to add and edit parameters related to measurements. Based on the predefined requirements for cold chain food management and on the analysis of the measurements, remaining shelf life is calculated and displayed in the time graph. The application also illustrates any anomalies in data. This thesis describes the process of creating a web application, which we developed with Laravel framework and MySQL database. Graphical user interface is customized for all kind of devices. For purpose of facilitating the testing a data generator was added which enables additional analysis of simulated cold chain events. User management functionality is also included. At the end, the web application was tested with realistic cold chain measurements.

Diplomsko delo je zasnovano kot spletni portal, ki je bil zgrajen s pomočjo standardnih spletnih tehnologij s poudarkom na ogrodjih Laravel in Vue.js. Pregled področja je pokazal, da portala, ki bi vključeval vse zahtevane cilje diplomske naloge, še ni. Spletni portal prikazuje novice, zunanje povezave, kontakte ter področja v 3. fokusnem področju in v 4. fokusnem področju razvojno-inovacijskega partnerstva SRIP HRANA. Prav tako je omogočen pregled podjetij in raziskovalnih institucij. Uporablja se za iskanje potencialnih možnosti za sodelovanje, ki bi vodilo v inovativne rešitve za povečanje produktivnosti na področju agroživilstva. Pred izdelavo portala so bili zbrani določeni podatki, administracijska stran pa skrbi, da se ti podatki lahko dodajajo, urejajo ali brišejo. Administracija in delovanje aplikacije sta opisani in predstavljeni z zaslonskimi posnetki, ki ponazarjajo potencialne možnosti za nadgradnjo in praktično uporabo. The diploma work is designed as a web portal that was built using standard web technologies with emphasis on the Laravel and Vue.js frameworks. The review of the field showed that the portal, which includes all the required goals of the thesis, is not yet available. The web portal displays news, external links, contacts and areas in the third focus area, and in the fourth focus area of the development and innovation partnership SRIP HRANA. It is also possible to review companies and research institutions. It is used to find potential opportunities for cooperation, leading to innovative solutions which increase productivity in the agro-food sector. Before the creation of the web portal, certain data were collected, and the administration page allows for these data to be added, edited or deleted. The administrative and operational functions of the application are described, and presented with screenshots illustrating potential options for upgrades and practical use.

Vzdrževanje in nadzor ustreznih temperaturnih in drugih pogojev hladne verige za hitro pokvarljive proizvode je eno od pomembnih raziskovalnih področij, saj ob nepravilnem ravnanju zavržemo ogromne količine hrane. Z implementacijo ``pametnih'' senzorskih sistemov in algoritmov lahko pravočasno zaznamo odstopanja in se nanje ustrezno odzovemo. V magistrski nalogi smo razvili in izdelali prototip senzorskega sistema za zajem in analizo podatkov v realnem času s podporno spletno aplikacijo. Mikrokrmilnik NodeMCU skrbi za komunikacijo s senzorji za temperaturo, vlago, kisik, ogljikov dioksid, etilen in svetlobo podatke pa zapisuje na spominsko kartico ali jih preko Wi-Fi povezave pošilja na strežnik. Na podlagi izmerjenih temperatur smo dinamično napovedovali dobo uporabnosti rib, sistem pa smo preizkusili tudi za analizo zorenja sadja in zelenjave. Preverjali smo pogoje hranjenja in na osnovi pridobljenih meritev predstavili rezultate senzorskih sistemov ter vpliv tvorbe etilena v jabolkih na kumare. Maintaining and controlling the appropriate temperature and other conditions of the cold chain for perishable products is important research area, since in case of improper handling, we lose huge amounts of food. With the implementation of smart sensor systems and algorithms, we can detect deviations and respond appropriately to them. In the master's thesis, we developed a prototype sensor system for real-time data monitoring and analysis with a supportive web application. The microcontroller NodeMCU ensures communication with sensors for temperature, humidity, oxygen, carbon dioxide, ethylene and light the data is recorded on a memory card or sent via Wi-Fi connection to the server. Based on temperature measurement, we dynamically predicted the shelf life of the fish. We tested our system with fruit and vegetables for analysis of ripening under cold storage conditions and the effect of ethylene in apples on cucumbers.

Senzorski moduli in naprave za merjenje temperature, in pogosto tudi vlage, se dandanes nahajajo že v celotni prehranski verigi. Vendar je le teh še vedno premalo, oziroma niso v zadostni meri upoštevani pri zagotavljanju nadzora kakovosti živil, kar priča tudi podatek o količini zavržene hrane, še preden ta pride do trgovskih polic. Podatki o hladni verigi pogosto niso na voljo, ali pa je dostop omejen na lokalne uporabnike zaradi nezadostne varnosti. V magistrski nalogi je predstavljena rešitev za zajem senzorskih podatkov s tehnologijo komunikacije kratkega dosega (angl. Near Field Communication, NFC) in dodatno zaščito podatkov s šifriranjem AES. Implementirali smo avtonomno izvedbo senzorskega sistema NFC (SS-NFC). Omogoča branje podatkov z mobilnim telefonom ali pa jih modul NodeMCU posreduje na spletni strežnik. Vključuje različne načine delovanja z uporabo komunikacije Wi-Fi, lokalnim shranjevanjem senzorskih meritev (`On-line', `Off-line'), šifriranjem podatkov in avtorizacijo uporabnika. SS-NFC smo analizirali s testiranjem temperature v hladni verigi in s preverjanjem senzorskih meritev temperature, vlage in svetlobe v hladilniku. S 3D tiskalnikom smo izdelali enostavno ogrodje prototipa za testiranje v realnem okolju. Sensor modules and devices for measuring temperature, often also moisture, are nowadays included in almost every step in the food supply chain. However, these numbers are still too small, or not sufficiently taken into account in ensuring food quality control, which is also evident by the amount of food waste before it comes to shelves. The master's thesis presents a solution for capturing sensor data with Near Field Communication (NFC) technology and additional data protection with AES encryption. We implemented an autonomous NFC sensor system (SS-NFC) for use in the cold chain. Data is readable by mobile phone or uploaded to a server using NFC reader and NodeMCU.The system provides various modes of operation using Wi-Fi communication or local storage of sensor measurements (`On-line', `Off-line'), data encryption and user authorization. SS-NFC was analysed by testing temperature in a cold chain and by evaluating the sensor measurements of temperature, humidity and light in the refrigerator. We made a simple SS-NFC prototype with 3D printer for easy testing in a real environment.

Uravnotežena prehrana je ključ do dobrega počutja. Da bi olajšali spremljanje in spodbudili ter izobrazili posameznika o primernih prehranjevalnih navadah, je v diplomskem delu opisan razvoj nutricistične aplikacije, ki je z uporabo komunikacije BLE povezana s kuhinjsko tehtnico. Z analizo obstoječih rešitev so bile določene funkcionalnosti, ki pripomorejo k boljši uporabniški izkušnji. Z raziskavo področja prehrane so bile identificirane najpogostejše napake v načinu prehranjevanja Slovencev. Na teh izsledkih je temeljilo oblikovanje aplikacije za operacijski sistem Android. S pomočjo majhne in prenosljive kuhinjske tehtnice omogoča enostavno beleženje hranil in vrste hrane s spremljanjem sestave zaužitih obrokov, kar nazorno prikaže v primerjavi s priporočenimi vrednostmi za pravilno prehranjenost. Balanced diet is key to well-being. In order to make the process of tracking eating habits easier and to educate individuals about appropriate food intake, the thesis describes the development of nutrition application which communicates with the kitchen scale. Based on the field analysis, the functionalities that improve user experience were identified. Field research helped determine the most common mistakes of the eating habits of Slovenians. Considering these findings, the application for Android operating system was designed. By monitoring the composition of consumed meals with the aid of a small and portable kitchen scale it allows simple tracking of nutrients and kind of food that are graphically compared to the recommended food intake values.
