This study contains the solutions for detouring after the flood in the Black Sea Region in Turkey back in the summer of 2021. Moreover, it proposes an emergency support facility location in the vicinity of the disaster area. However, the region's problem is lacking a detouring plan for transportation management in the case of road closures due to flood effects such as damaged bridges or landslides. Since the region is prone to heavy precipitations and the terrain is appropriate for possible floods and landslides, the region's transportation management during or after a disaster is vital. In this manner, Dynamic Programming (DP) is utilized for arranging the detours for the transportation road network in the area of disaster. Furthermore, Stochastic Based Optimization (SBO) techniques are powerful in solving network optimization problems. Hence, location analysis via Whale Optimization Algorithm (WOA) is conducted for siting an emergency support facility according to the spatial characteristics of the road network. Results indicate that although detouring lengthens the transportation paths between origins and destinations, disasters such as floods can obligate such interventions. Moreover, the deterioration of a network link plays a critical role because it changes the spatial topology. Therefore, a facility for emergency cases is located based on the current data in the region for quick intervention using an SBO technique of WOA. No sponsor

The Russia-Ukraine war, its reasons and impact have been discussed by diplomats, politicians and intellectuals worldwide. While many accuse the Russian leadership and in particular Russian President Vladimir Putin for the war, some others criticize Western countries and principally the US for NATO’s eastward expansion and for disregarding Russia’s security concerns. Chinese intellectuals with diverse academic and political backgrounds have also contributed to these discussions and offered their assessments about the war in Ukraine as well as what kind of a policy China should follow. However, because of the sensitive relationship between the authoritarian party-state and Chinese intellectuals, Chinese intellectuals are in a delicate situation compared to intellectuals in the West. Despite this, the Chinese state’s relatively balanced and neutral stance and decision of not openly taking sides in the war provided a ground for Chinese intellectuals to publicly share their thoughts about both the war itself and China’s position towards Russia’s aggression. Nevertheless, due to its close relationship with Moscow, the Chinese state allows only a restricted space for intellectuals to share their views about the war, especially to anti-Russia voices. This study surveys these debates among Chinese intellectuals about the war in Ukraine as well as the policies that the Chinese leadership should follow., Rusya-Ukrayna savaşı, savaşın nedenleri ve etkileri dünyanın dört bir yanındaki diplomatlar, politikacılar ve aydınlar tarafından tartışılmaktadır. Tartışmaya katılanları birçoğu savaşın gerekçesi olarak Rus liderliğini ve özellikle Rusya Devlet Başkanı Vladimir Putin'i gösterirken, bazıları ise Batılı ülkeleri, özellikle de ABD'yi NATO'nun doğuya doğru genişlemesi ve Rusya'nın güvenlik kaygılarını göz ardı etmeleri nedeniyle eleştirmektedir. Farklı akademik ve siyasi arka planlara sahip Çinli aydınlar da bu tartışmalara katılarak Ukrayna'daki savaş ve Çin'in nasıl bir politika izlemesi gerektiği konusunda değerlendirmelerde bulunmuşlardır. Ancak otoriter parti-devleti ile Çinli aydınlar arasındaki hassas ilişki nedeniyle Çinli aydınlar Batı'daki aydınlara göre hassas bir konumdadır. Buna rağmen Çin devletinin savaş karşısında gösterdiği görece dengeli ve tarafsız duruş ve savaşta açıkça taraf tutmama kararı, Çinli aydınların hem savaş hem de Çin'in Rusya'nın saldırganlığına karşı tutumu hakkındaki düşüncelerini kamuoyu önünde paylaşmalarına zemin hazırladı. Bununla birlikte Çin devleti, Moskova ile sahip olduğu yakın ilişki nedeniyle Çinli entelektüellerin, özellikle de Rusya karşıtı görüşe sahip olanların, savaş hakkındaki görüşlerini paylaşmaları için yalnızca sınırlı bir alan açmaktadır. Bu çalışma, Çinli aydınlar arasında Ukrayna'daki savaş ve Çin liderliğinin izlemesi gereken politikalar ile ilgili tartışmaları incelemektedir.

Objective: This bibliometric study identifies the studies, institutions and journals with the highest impact by analyzing the articles published about percutaneous nephrolithotomy (PCNL) and further to establish trend topics and to holistically summarize and interpret collaboration among countries. Materials and Methods: Studies published about PCNL between 1975-2020 were downloaded from the Web of Science (WoS) database. They were analyzed using bibliometric and statistical methods. Spearman's correlation coefficient was used for correlation analysis. Non-linear regression analysis was used to estimate the number of publications in the coming years. Results: A total of 4170 publications were found and 1936 (46.4%) of these publications were articles. We observed that the articles on PCNL have gradually increased in an exponential trend. Top 5 countries having contributed most to the literature ranked as Turkiye (n=376), USA (n=332), China (n=323), India (n=210) and Iran (n=123). Top 3 most active institutions were ranked as Guangzhou Medical University (n=63), University of Health Sciences Turkiye, İstanbul Haseki Training and Research Hospital (n=52) and Başkent University (n=32). Conclusion: In our study, we observed that there has been an increase in the number of PCNL-related publications over the course of time. Besides, we determined that recent publications, mainly focused on the success and reliability of PCNL. In this context, there has been a steady increase in the number of studies on the use of Guy's scoring system for preoperative selection of eligible patients and surgical approaches such as mini PCNL, prone position.

COVID-19 pandemic , *PANDEMICS - Abstract
The Covid-19 pandemic has presented an extraordinary and unprecedented situation. In their efforts to end the pandemic, countries worldwide followed different approaches to combat the virus. Among these, China emerged as the prime example of an authoritarian model of virus management, whereas South Korea managed to slow down the pandemic with a liberal democratic approach. Although both were successful in pandemic management, China and South Korea have different and contrasting images in the international area. This study analyzes how China's and South Korea's pandemic management models and their international reception differ from each other. It claims that while both models were largely applauded domestically, in the international sphere, China, after early acclaim, ended up with a more negative and controversial image, whereas South Korea created a relatively more positively regarded model. Still, compared to the South Korean model, many more countries emulated and implemented the Chinese model worldwide. [ABSTRACT FROM AUTHOR]

Günümüzde yenilenebilir enerji kaynaklarından olan güneş enerjisinden fotovoltaik (PV) paneller kullanılarak elektrik üretimi amaçlı uygulamalar mevcuttur. Yapılarda, marjinal arazilerde veya gölgeleme elemanlarında bu tür kullanımlar görülmektedir. Ancak PV panellerin yapılar üzerine ek yük getirmesi ve strüktür ihtiyacı yaratması nedeniyle PV panellerin kullanımları zorlaşabilmektedir. Bu nedenle PV panelleri karayollarında kullanmak yapılardaki ek yükleri azaltabilir. PV panellerin yollarda kullanılması hem yolların aydınlatma gibi çeşitli ihtiyaçlarının azaltılması hem de üretilen fazla elektriğin şebekeye verilerek yenilenebilir enerji kullanım alanlarının arttırılması hedeflenebilir. Ancak, yollardaki trafik akışının ve yol eğiminin enerji üretimine etkisi büyük önem arz etmektedir. Bu çalışmanın amacı, karayolları üzerinde PV panel kurulumu sonrası yollardaki trafik akışı ve yolların eğimi göz önüne alınarak elektrik üretimini değerlendirmek ve hangi çeşit yollardan enerji üretimi daha fazla olabileceğini ortaya çıkarmaktır. Çalışmanın bir diğer amacı, trafik akışının enerji üretimine etkisini betimleyen bir parametre ileri sürerek yolların trafik akışına göre enerji üretimi potansiyelini ortaya çıkarmaktır. Bu hesaplamalar için Türkiye’nin en yoğun nüfuslu illerinden Antalya’daki hafta içi trafik akışı gözlemlenmiştir. Analizler sonucunda trafik akışının fazla olmasının PV panellerin enerji üretimine etkisi incelenmiş, Kuzey – Güney (K-G) ve Doğu – Batı (D-B) yönünde olan yolların birbirleri ile karşılaştırılması yapılmıştır. Trafik akışındaki düşük seviyeler ve yolların güneye doğru eğime sahip olması yoldaki elektrik üretimini olumlu etkilemektedir. Trafik akışı gibi bir ulaşım parametresinin enerji üretimine etkisinin incelenmesinden elde edilen sonuçlar, Antalya’da uygulanabilecek altı bölgedeki yolun elektrik üretim potansiyelini açığa çıkarmıştır. Bulgulara doğrultusunda, Gazi Mustafa Kemal Bulvarı’nın elektrik üretim potansiyeli diğer ölçüm bölgelerine göre daha fazladır., Today there are applications for electricity generation by using photovoltaic (PV) panels from solar energy which is one of the renewable energy sources. Such uses are seen in buildings, marginal lands or shelters. However, the use of PV panels can be difficult because PV panels impose additional load on the buildings and create a need for load bearing structure. For this reason, using PV panels on roads can reduce the additional loads on buildings. The use of PV panels on the roads can aim both to reduce the various needs of roads such as lighting and to increase the use of renewable energy by giving the excess electricity generated to the electric supply system. However, the effect of traffic flow and road slope on the energy production is of great importance. The aim of this study is to assess the electricity generation by considering the traffic flow and the slope of the roads after the installation of PV panels and to reveal which types of roads can be more productive. Another purpose of the study is to reveal the energy generation potential of the roads according to the traffic flow by putting forward a parameter that describes the effect of traffic flow on energy production. For these calculations, weekday traffic flow in Antalya, one of the most densely populated provinces of Turkey, has been observed. As a result of the analyzes, the effect of the high traffic flow on the energy production of PV panels was examined, and the roads in the North - South and East - West directions were compared with each other. Low levels of traffic flow and the slope of the roads towards the south positively affect the electricity generation on the road. The results obtained from the examination of the effect of a transportation parameter, such as traffic flow, on energy production revealed the electricity generation potential of six regions in Antalya. According to the main outputs, Gazi Mustafa Kemal Bulvarı has more potential for energy generation compated to the other surveying areas.

Bu çalışma, önceki benzer çalışmalardan üç ana yönden ayrılmaktadır. Birincisi, yöntem olarak diğerlerinden ayrılarak ülke çapında sadece tek bir lokasyondaki havalimanı tesisi değil kümeleme yöntemi uygulanarak bölgesel hizmet verebilecek en uygun tesisler tespit edilmiştir. İkincisi, önceki çalışmalarda İstanbul Havalimanı henüz hizmete girmediğinden dolayı değerlendirmeye alınmamışken, bu çalışmada optimizasyon hesaplarına dahil edilmiştir. Üçüncüsü, yeni durumun önceki çalışmalara nazaran daha güncel verilerle ve daha güncel bir optimizasyon yöntemi olan ağaç tohum algoritması kullanılarak optimum çözümler üretilmiştir. Trafik verileri, trafiğe dayalı ağırlık katsayıları ve ulaşım mesafelerinin elde edildiği konum verilerine dayanarak yapılan analizler sonucunda, toplam on altı havalimanı kendi bölgelerine, özellikle herhangi bir felaket sırasında veya sonrasındaki acil durumlarda, servis sağlayabilecek ideal havalimanları bu çalışmada ortaya çıkarılarak tavsiye edilmiştir. Bu araştırmanın önerileri doğrultusunda, herhangi bir acil durumda gerekli olan ve havayolu ile sağlanabilecek hizmetler sayesinde zaman ve gider kaybının azaltılması gibi amaçlar gözetilirken daha da önemlisi can kaybının en az düzeye indirilmesi konusunda ilerleme kaydedilmesi beklenmektedir. This study differs from previous similar studies in three main directions. Firstly, the location of the most suitable facilities that can provide regional service were determined by applying clustering method. Thus, not only one airport facility in a single location serving across the country was determined, which separates this research from the others. Secondly, in the previous studies, Istanbul Airport was not taken into account because it has not been put into service. Therefore, this study takes that particular airport into consideration. Thirdly, optimum solutions for such new situation were produced with more up-to-date data and using a modern optimization method, the tree seed algorithm. As a result of the analyzes made based on traffic data, traffic-based weight coefficients and location data from which transportation distances were obtained, a total of sixteen ideal airports were recommended that can provide service to their regions, especially during emergencies or after any disaster. In accordance with the suggestions of this research, it is expected that progress will be made in minimizing the loss of time and expense, and especially minimizing the loss of life thanks to the services which can be provided by air transportation in any emergency.

Uluslararası Akademik Araştırmalar Kongresi (3. : 2020) Nüfus artışı ile birlikte günlük yaşantımızda, özellikle trafik sistemlerinde, servis sistemlerinin yetersizliği doğrultusunda bekleme sorunları ile sık sık karşılaşılmaktadır. Bu sorunların önüne geçmek için trafik sistemleri, hizmet maliyetlerini düşürmeyi, hizmet niteliğini artırmayı ve yol kullanıcılarının bekleme zamanını düşürmeyi amaçlamalıdır. Araştırmamızda Antalya’da bulunan bir alışveriş merkezi otopark girişi gözlemlenmiştir. Kuyruk Teorisi modellerinden en uygun olanı eldeki vaka çalışması için incelenip seçilmiştir. Yapılan çalışmada, bekleme ve hizmet sürelerinde gözlemlenen problemler tespit edilmiştir. Toplanan veriler akademik amaca uygun olarak kaydedilmiştir. Analizler sonucunda bekleme süresini en aza indirecek ve daha hızlı hizmet alınabilecek bir kuyruk sisteminin oluşturulması amaçlanmıştır. D/D/1 kuyruk rejimi önerilen araştırmamızda, hem grafiksel çözümlerle hem de matematiksel denklemlerle problem çözülmüştür. Çalışmamızın amacı doğrultusunda, yolcu bilgilendirme sistemleri, değişken mesaj işaretleri gibi akıllı ulaşım sistemleri otopark girişinde trafiği düzenlemede yardımcı olması için tavsiye edilmiştir. With the increase of population, problems of waiting on the queue are frequently encountered in our daily life, especially in traffıc systems, with the insufficiency of service systems. To prevent these problems, traffıc systems should aim to reduce service costs, improve service quality and reduce the waiting time of road users. İn our research, a shopping mall parking lot entrance in Antalya was observed. The most suitable queuing theory models were examined and selected for the case study. Accordingly, the problems observed during the waiting and service periods were determined. The data collected were recorded for academic purposes. As a consequence of the analysis, it is aimed to create a queuing system that Will minimize waiting time and provide faster service. İn our research, D/D/I queuing regime was proposed and the problem was solved not only with graphical analysis and also mathematical equations. For the purpose of our study, İntelligent transportation systems such as passenger information systems and dynamic message signs have been recommended to assist in regulating traffıc around the parking lot.

International Congress on Academic Research (3. : 2020 : Berlin, Germany) Traffic is defined as the state and movement of pedestrians, animals, goods and vehicles. Traffic cannot be defined as a system of roads in which only flow is directed, because traffic must be harmonized. One of the ways to do this is traffic calming implementation which are applications designed to calm traffic and decrease crash rates. The main goal is to reduce speed of vehicles, increase pedestrian and cyclist safety, decrease noise of traffic, provide a smooth traffic flow. In this study, the data was collected from an official website presenting traffic volumes of highways. Accordingly, considering trade-offs and location audit, the most convenient site was chosen in Korkuteli-Tefenni road district with the help of traffic calming devices and their utility attributes. Then, the most appropriate horizontal traffic calming as center blisters or slow points (chicanes) that effectively calm traffic was applied. According to our analysis, the results basically show that slow points are more operative and advantageous than center blisters for the particular location selected. Our study also proved that, compared to the literature, because while center blisters remain ineffective on the traffic volume, slow points can reduce the average traffic volume up to a certain degree.

Amaç: Karaciğer fibrozis tanı ve skorunun belirlenmesi için birçok noninvaziv test çalışılmıştır. Bu çalışmada, kronik hepatit B (KHB) olan hastalarda platelet parametrelerinin ve karaciğer fibrozisin evresi arasındaki ilişkiyi araştırmayı amaçladık. Gereç ve Yöntem: Çalışmaya toplam 140 biyopsi ile kanıtlanmış naiv KHB olgusu dahiledildi. HBV-DNA düzeyi, karaciğer enzimleri ve fonksiyon testleri, beyaz kan hücresi sayısı, platelet parametreleri, hemoglobin, histolojik aktivite indeksi (HAI) ve diğer rutin biyokimyasal parametreler test edildi. Karaciğer biyopsi örnekleri modifiye Ishak skorlama sistemi kullanılarak incelendi. Hastalar karaciğer fibrosis şiddetine göre modifiye İshak puanlama sistemi ile F0-2 ve F3-6 olarak iki gruba ayrıldı.Bulgular: F0-2 ve F3-6 grupları arasında platelet (PLT), ortalama platelet hacmi (MPV), platelet dağılım genişliği (PDW) ve platelecrit (PCT) açısından anlamlı fark yoktu. Bu iki grup arasında HAİ, aspartat transaminaz (AST), gama glutamil transaminaz (GGT), yaş ve lenfosit parametreleri açısından anlamlı fark vardı. Karaciğer fibrozis evresini tahmin etmede kullanılmak üzere birçok farklı kombinasyondan oluşan (AST x Yaş x Lenfosit) /√PLT) formülasyonu araştırıldı. Sonuç: Yeni indeksimiz diğer noninvaziv skorlama sistemlerine göre daha sensitivitesi yüksek olmakla birlikte noninvaziv belirteç olarak güvenle kullanılabilmesi için ileri karaciğer fibrozis düzeyine sahip olan hastaların daha fazla olduğu, daha geniş örneklem büyüklüğüne sahip çalışmalara ihtiyaç vardır., Purpose: Many noninvasive tests have been studied for the diagnosis and determining the liver fibrosis score. In this study, we aimed to research the correlation of platelet parameters and stage of liver fibrosis in patients with chronic hepatitis B (CHB).Materials and Methods: A total of 140 biopsy-proven naive CHB cases were included in the study. HBV-DNA level, liver enzymes and function tests, white blood cell count, platelet parametres, hemoglobin, histological activity index (HAI) and other routine biochemical parameters were tested. Patients were divided into two groups as F0-2 and F3-6 with Ishak scoring system according to the severity of liver fibrosis.Results: There was no significant difference between the groups F0-2 and F3-6 in terms of, platelet (PLT), mean platelet volume (MPV), platelet distribution width (PDW) and plateletcrit (PCT). There was a significant difference between these two groups for HAI, aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), age and lymphocyte (LYM) parameters. The formulation of (AST x Age x LYM) / √PLT)which was formed from many different combinations, was investigated in order to be used in predicting the liver fibrosis stage. Conclusion: Although our new index is more sensitivitythan other noninvasive scoring systems, it is needed to have a larger sample size in patients with severe stage liver fibrosis in order to be used safely as a noninvasive marker.

- Abstract
Tüm dünyayı etkisi altına alan COVID-19 pandemisi günlük yaşamı tüm yönleriyle etkilemiştir. Beklenmedik iş kayıpları,izolasyon, COVID-19 enfeksiyonlarının yol açtığı hastalık ve ölümlerin artışı yaşamlarımızı oldukça değiştirmiştir.COVID-19 pandemisi dünya çapında bir sağlık sorunu olmasının yanında, İBH olan hastalarının takip ve tedavilerini deetkilemiştir.Biz bu çalışmamızda COVID-19 pandemi döneminde İBH hastalarında yaşam kalitesi, hastalık aktivitesi ve anksiyetedüzeylerini değerlendirerek, hastalığın takip ve tedavisine yön verilebilmeyi ve hasta-hekim ilişkisine yeni bir boyutkazandırabilmeyi amaçladık.Çalışmamıza Gazi Üniversitesi Tıp Fakültesi Gastroenteroloji polikliniğine ayaktan başvuran 62 İBH’li hasta ve 60 sağlıklıkontrol grubu dahil edildi.Hastaların ve sağlıklı kontrol grubunun anksiyete düzeyleri ve yaşam kaliteleri karşılaştırıldı.Aynı zamanda anksiyete düzeyleri ve yaşam kalitesi demografik veriler ve hastalık aktivasyonu ile karşılaştırıldı. Buna ekolarak İBH hastalarına COVID19- pandemi sürecindeki tutum ve davranışlarını değerlendirmek için anket yapıldı.Sonuçlar değerlendirildiğinde; İBH hastalarının yaşam kaliteleri daha kötü ve anksiyete düzeyleri daha yüksek bulundu.Aktif hastalığı olanların yaşam kalitesi daha kötü, anksiyete düzeyi daha yüksek bulundu.COVID-19 pandemisininhastalığı için risk oluşturduğunu düşünenler ve düşünmeyenlerin yaşam kaliteleri ve anksiyete düzeyleri benzer tespitedildi.Ancak hastaların çoğunun pandemi ve kullandığı tedaviler yüzünden risk altında olduğunu düşündüğü, insanlarlailetişime geçmekte zorlandığı ve yolculuk yapmaktan kaçındığı görüldü.Hastaların hemen hemen hepsi maske, mesafeve hijyen kurallarına dikkat etmekteydi.Sonuç olarak, COVID-19 pandemi sürecinde İBH ile takipli hastaların normal popülasyona göre yaşam kaliteleri düşük,anksiyete seviyeleri yüksek bulunmuştur.Bu süreçte hasta-hekim ilişkisine daha çok dikkat edilmeli, iletişim gerekirseteletıp uygulamaları ile gerçekleştirilmeli, hastalara daha çok bilgi verilmeli ve böylece yaşam kaliteleri arttırılmalı,hastane maliyetleri en aza indirilmelidir. COVID-19 pandemic has significantly changed our lives through various ways including social isolation,emotional andphysical distress caused by COVID-19 related hospitalizations and deaths, and increased unemployment rates.Eventhough the COVID-19 pandemic became a worldwide health problem affecting millions,patient’s with IBD constituteda special patient population which has been particularly impacted by the poor outcomes of the unprecedentedsituation.In this study,we assess the quality of life,anxiety levels and disease flare-ups in patients with IBD duringCovid-19 pandemic aiming to guide/assist the management of the patients and bring a new perspective into thephysician-patient rapport.The study includes the patient group with 62 IBD patients who visited Gazi University Schoolof Medicine Gastroenterology outpatient clinic and the control group with 60 healthy individuals.The quality of life andanxiety levels of the individuals in the patient group vs control group were compared.The study demonstrated higher anxiety levels and lower quality of life in patients with IBD compared to the control group.Higher anxiety level andlower quality of life was also found in patients with active disease as compared to others.However, most of the patientswere concerned about being at increased risk due to their underlying health condition and current treatment.In orderto address the patients’ mental health and the quality of life, physician-patient relationship must be maintained strongand satisfying in these difficult times through telemedicine visits and frequent follow ups which would eventually helplowering the cost of hospitalizations as well.

- Abstract
Pseudogout (PG) is an inflammatory arthropathy that develops due to the accumulation of calcium pyrophosphate dihydrate crystals in synovial structures. Herein, we present a 59-year-old male patient with PG developed as a result of zoledronic acid (ZA) infusion, which was administered due to primary hyperparathyroidism. The patient with parathyroid adenoma was given ZA since the calcium level did not decrease despite intravenous saline and loop diuretic. One day after ZA administration, the patient had severe pain, fever, and swelling in joints. The radiograph showed chondrocalcinosis. Calcium pyrophosphate deposition were observed in the arthrocentesis fluid under polarized light. The patient's symptoms regressed after anakinra and colchicine treatment. To the best of our knowledge, this is the first case report of a PG attack after ZA treatment for primary hyperparathyroidism. Additionally, there have been few cases of PG after bisphosphonate treatment for osteoporosis in the literature, signifying that more care should be taken when administering bisphosphonate therapy in patients with risk factors.

The product which we have dried is rose hip, which is utilizing for cooking jam in winter, even brew tea, that have high nutritional values and have countless merits for human health. We started the study with the experiment of drying the rose hips, which were cut into 5 mm slices and removed from the seeds, by keeping them in the refrigerator. By recording the experiments of the rose hips, which were placed in our drying device in 7 samples of 100 grams, one by one; The weights of the 2, 4, 6, 8, 10, 12 and 14 hour experiments were measured, and a kinetic model was created. Moreover, the moisture ratio (MR) was calculated. A total of 8 different kinetic drying models were studied by using the MATLAB program in the presence of experimental data, and according to the results of the experiment, X2: 2,156×10-4 , RMSE: 0.011874 value was regulated. It has been observed that the closest value of R2 to1 is R2 with the amount of R2 =0.9985. According to the results of the experiment, it was determined as the DIFFUSION APPROACH model that gave the best results among eight models. Besides, we found the effective diffusivity value, which was 1,99828×10-10 m2/s for the mentioned Rose hip slices. It was confirmed that the calculated effective diffusivity value was within the reference range mentioned in the literature (10-12 – 10-8 m2/s) for food products.

Unmanned aerial vehicles (UAVs) are used to physically interact with humans and urgent data collection in a shared workspace. They are flying collaborative robots that can be remotely supervised through a software-controlled flight plans in their embedded systems, working in conjunction with built-in sensors and global positioning system modules. Drones are widely used in safety and critical intelligent transportation systems applications to enhance performance and well-being. UAVs can fly over the road to monitor and observe possible traffic destructions. Path planning (PP) process in UAVs gained a great interest in the literature. That is due to its significant effects at the application-level performance. PP of UAVs in the internet of things era can be achieved via several approaches. As the name implies, static-based PP is dependent on a static set of data collectors to relay and report data. For a particular engineering area, transportation engineering, the mathematical methods, and related algorithms are commonly applied to real cases. No sponsor

ARUD 5th Congress of the Balkan-States-Anesthesia-Days -- MAY 09-12, 2018 -- Gaziantep, TURKEY Aim: Children's perception of pain may vary depending on defenselessness, negative and exaggerated behavior, level of persuasion, personality characteristics, and previously experienced negative experiences. This study was designed to investigate the relationship between anxiety and postoperative pain perception of children and the family's anxiety about the child's pain and negative attitudes on the effects of the pain. Material and Methods: Thirty-five patients undergoing appendectomy between August-December 2017 were included in this prospective study. Seven patients were excluded because of incongruity. Face, leg, activity, cry, consolidation (FLACC), preoperative anxiety scale of Yale, and Post-Anesthetic Delirium scale were applied. In the postoperative period, parents and children were asked to complete a pain questionnaire. Results: It is found that, as family education level increased, the anxiety of both children and parents decreased. The parents were found to have fewer levels of rumination as the level of education increased when the effect of postoperative analgesia selection on the visual analog pain scale (VPS) was investigated, there was a statistically significant difference between pain VPS scores only after surgery. It was found that mothers were more anxious than fathers. A moderately positive correlation was found between the VPS score and the child and parental rumination scale scores. It was seen that the education level of the family had a positive effect on the pain perception of the child. Discussion: The results of the surgical experience in the long-term memory revealed that the children had a comfortable postoperative period and that they did not think much about the operation, but that they would be afraid to undergo surgery again.

Oxidative Stress ,Menopause ,Vitamin D ,Fish Oil ,Exercise - Abstract
Menopause is the permanent cessation of ovarian follicular activity and the menstrual cycle. There is little physiologic and histologic data concerning the possible effects of menopause on respiratory tract and possible beneficial agents for respiratory tract against the effects of menopause. The rat lungs and trachea have been obtainedfrom young and old rats which were treated with either vitamin D (VitD; 1000IU/kg/week),Fish oil (FO; 0.8 mL/kg/week) or exercise (running 45 minutes/3 times/week) for 12 weeks after one week overiectomy (OVX) followup. Oxidative stress markers found increased at OVX and OVX+E groups. However, oxidative stress marker levels were lower at OVX+E group than OVX group. Vitamin D and fish oil also caused decreased oxidative stress at lung tissue compared to OVX group. OVX group had histological changes such as epithelial desquamation, peribronchial smooth muscle hypertrophy, peribronchial lymphoid follicles, Type 2 pneumocyte hyperplasia; however, none of them was found at exercise group. Ovariectomy caused respiratory system effects in rats. Menopause cause oxidative stress; however, exercise, vitamin D and fish oil have protective effects against oxidative stress at lungs at different quantities. Ovariectomy group has the greatest damage compared to other groups. Exercise is the best protective modality against the effects of menopause at respiratory system.

Clinical, anthropometric, pathological and laboratory (calsiyum, phosphor, alkalenphosphataz (ALP), parathormon (PTH), 25OHvitamin D levels) properties of patients were detected retrospectively. Lumbal (L1-L4) bone mineral densityleve lsmeasuredvia DEXA (Dual Energy X-Ray Absorptiometry) were evaluatedand Z scoresduetocronologicalageandheightagewerecalculated. Results: Meanage of 43 patients (34 girl/9 boys) was 9.9±4.8 (2.5-17.7) years. 30.2% (n=13) was 0-6 years old, 30.2% (n=13) was 7-11 years and 39.5% (n=17) wasover 11 years. BMD Z scoreduetochronologicalage was -0.83±1.1 (-3.6-1.6) and -0.18±1.1 (-3.6-1.8) duetoheight age. BMD Z scoresduetochronologicalagewas>-1 in 51.2% of thepatients (n=22), between -1 and -2 in 34.9% (n=15) and0.050). Conclusion: Delayed diagnoseageseffects bone mineral densitynegatively in Celiacdisease. Diagnose in earlyagesdecreases bone mineral leakanddecreasesmorbidity in patients with osteopeniandosteoporosisviatreatmentposibilities.
