In this study Arduino card based mobile robot design was realized. This robot can serve as a security robot, an auxiliary robot or a control robot. The designed robot has two operation modes. The first operating mode is autonomous mode. In this mode, the robot detects the surroundings with the help of ultrasonic sensors placed around it, and keeps track of the places it passes by using the encoder. It is able to navigate without hitting any place and passing from where it passes, and it transmits the patient's pulse and temperature condition to the user by other systems installed on it. Also the IP camera sends the scene on the screen. The emergency button to be placed next to the patient sends information to the user in emergency situations. If the abnormality is detected in the temperature and pulse again, the user gives a message. When the pre-recorded drug use times come, the system can alert the patient. The second mode is manual mode. In this mode, the user can move the desired direction of the robot with the Android operating system. In addition, all data received in autonomous mode can be sent to the user. Thus, the user can control the mobile robot with the camera image even if it is not in the vicinity of the robot., Comment: 5 pages, in Turkish language, 6 figures, journal of intelligent systems with applications, 2019

Determination of the optimal route in transportation activities is one of the major problems in transportation. Therefore, efficient techniques deserve our utmost attention to detect optimal routes. In this study, a novel method called Cluster Path Covering (CPC) has been developed and introduced to identify a route based on a sequence of location points on a network. There are already models to minimize the total path cost between the pair of nodes following a kind of sequence. However, our method aims to minimize the path cost, including the neighbourhood accessibility of the path nodes on the network. One of the major challenges for the new model is to reveal the accessibility costs between the nodes. The methodology presents the CPC method clustering the location points on a network and indicating the optimum point for each cluster. Then, the CPC method generates the best path by connecting the specific location points representing the clusters. Moreover, the shortest covering of the neighbourhood path problem (SCNPP) is introduced in this study. The novel CPC method is utilized for SCNPP, a distinctive version of the shortest covering path problem (SCPP). The performance of the CPC method is then tested on two different benchmark networks. According to the results, it provides robust and efficient outcomes for decreasing the routes' transportation costs (e.g., distances). The issues that can be solved via the CPC method include the accessibility costs of public transportation paths and the locations of stops by minimizing the costs. [ABSTRACT FROM AUTHOR]

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.

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.

Spor bilimleri içinde önemli bir yere sahip olan antrenman ve egzersiz ile ilgili küresel çalışmaların sayısındaki artışa rağmen literatürde halen bibliyometrik çalışmalar bulunmamaktadır. Bu çalışma, antrenman ve egzersiz konusunda yayınlanmış bilimsel makaleleri bibliyometrik yöntemlerle incelemeyi amaçlamaktadır. 1980-2021 yılları arasında yayınlanan antrenman ve egzersiz makaleleri Web of Science'dan (WoS) indirilmiştir. Ülkelerin makale sayıları ile bazı gelişmişlik göstergeleri arasındaki korelasyon analizleri için Spearman korelasyon katsayısı kullanıldı. Üstel düzeltme, sonraki yıllarda yayınlanacak makalelerin sayısını tahmin etmek için kullanıldı. Atıf analizlerini ve trend konularını belirlemek için ağ görselleştirme haritaları kullanıldı. Toplam 37408 makale analiz edildi. Literatüre katkı sağlayan ilk 3 ülke ABD (n=13227), İngiltere (n=4481), Kanada (n=3211) oldu. En aktif dergiler Journal of Applied Physiology (n=4338), Medicine and Science in Sports and Exercise (n=3292), Journal of Strength and Conditioning Research (n=2743) oldu. En aktif ilk 3 kurum University of California System (n=696), University of Copenhagen (n=678) ve University of North Carolina (n=644) idi. Literatüre en aktif katkıyı yapan kişi William J. Kraemer'dir (Makale Sayısı=223). Antrenman ve egzersizle ilgili bu kapsamlı bibliyometrik çalışmada 37408 makalenin bir özetini paylaştık. Son dekatta (2013-2021) çalışılan konular direnç antrenmanı, futbol, atletik performans, yüksek yoğunluklu interval antrenman, spor, gençler, takım sporları, antrenman yükü, sakatlık önleme, sağlık, yaşam kalitesi, egzersiz terapisi, obezite, aerobik egzersiz, kas gücü, biyomekanik, denge, yürüyüş, kalp hızı değişkenliği ve hipertansiyon olarak belirlendi., Despite the increase in the number of global studies on training and exercise, which have an important place in sports sciences, there are still no bibliometric studies in the literature. This study aims to analyse the scientific articles that have been published on training and exercising by using bibliometric methods. Articles on training and exercise published between 1980 and 2021 were downloaded from the Web of Science (WoS). Spearman correlation coefficient was used for the correlation analysis between the number of articles and some development indicators of the countries. The exponential smoothing was used to estimate the number of articles to be published in the next years. Network visualization maps were used to identify citation analyses and trending topics. A total of 37408 articles were analysed. The top 3 contributing countries to the literature were USA (n=13227), UK (n=4481), Canada (n=3211). The most active journals were Journal of Applied Physiology (n=4338), Medicine and Science in Sports and Exercise (n=3292), Journal of Strength and Conditioning Research (n=2743). The top 3 most active institutions were University of California System (n=696), University of Copenhagen (n=678), University of North Carolina (n=644). The most active contributor to the literature was William J. Kraemer (Number of articles=223). We shared a summary of 37408 articles in this comprehensive bibliometric study on training and exercise. The topics studied in the last decade were determined as resistance training, football, athletic performance, high-intensity interval training, sports, youth, team sports, training load, injury prevention, health, quality of life, exercise therapy, obesity, aerobic exercise, muscle strength, biomechanics, balance, gait, heart rate variability, and hypertension.

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.

Tourism revenues and foreign debts are among the important variables that bring source funding in foreign currency for the economies of the countries. The aim of this study is to reveal the relationship between tourism revenues and foreign borrowing for the Turkish economy. For this purpose, the analysis was carried out between 2003Q1 and 2021Q1 using the Johansen-Juselius (1990) cointegration method and the error correction model. According to the findings, there is one cointegration relationship between the related series and the error correction mechanism works. In addition, in the analysis, it was found that the direction of the relationship was from tourism revenues to foreign borrowing and it was determined that 1% increase in tourism revenues in the long term caused a 0.262% decrease in foreign debts in the related period. The research is very important for the Turkish economy within the framework of the subject discussed in terms of gaining the literature., Ülke ekonomileri için turizm gelirleri ve dış borçlar, döviz cinsinden fon kaynağı yaratan önemli değişkenler arasında yer almaktadır.

- 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.

This study has been carried out with "Freeze Drying" topic, and even, freeze drying technology (FD), which has seen as a healthy drying model that increases the shelf life of the products and preserves the aroma values it contains. 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.

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.

Çin düşünce dünyasında bir bütün olarak Mao Zedong sonrası dönemde, özellikle de 1989 Tiananmen olaylarını izleyen 1990’lı yıllarda bir Rönesans yaşanmıştır. Bu dönemde bir yandan liberalizm, eleştirel sosyalizm, Yeni Konfüçyüsçülük ve milliyetçilik gibi yeni düşünce akımları ortaya çıkar ve bunlar Çinli aydınlar arasında hızla yayılırken, bir yandan da devlet ve Çin Komünist Partisi (ÇKP) ile Çinli aydınlar arasındaki ilişki büyük bir dönüşüme uğramıştır. Bu süreçte ÇKP’nin bilgi üretimi üzerinde Maocu dönemde kurduğu egemenlik önemli ölçüde zayıflamıştır. Günümüzde devlet ile Parti, fikir üretimini ve entelijansiyayı denetim altında tutma yetilerini tamamıyla kaybetmemişse de onları yönlendirmekle yetinmek durumundadır.Çin, akademik yazında ağırlıklı olarak otoriter bir tek parti sistemi olarak ele alınmaktadır. Bu durum, Çin iç siyaseti ve entelektüel bilgi üretimindeki çok sesliliğin gözden kaçırılmasına ve ülkenin iç siyasi meselelerde tek sesmiş gibi algılanmasına yol açmaktadır. Halbuki Çinli aydınlar, özellikle 1990’lardan itibaren ülkenin ekonomik, siyasi ve toplumsal meseleleri ile ilgili yoğun bir tartışma içine girmiştir. Dünya düzenine ve Çin yönetim sistemine yönelik farklı yaklaşımlara sahip düşünce akımlarına mensup Çinli aydınlar, bir yandan diğer düşünce akımlarına mensup aydınlar ile düşünce üretimini denetim altına almak ve devletin karar alma mekanizmalarını etkilemek için mücadele halindeyken bir yandan da kendi aralarında görüş farklılıkları yaşamaktadır. Bu çalışma, Çin düşün dünyasında 1990’lardan bu yana önemli bir yere sahip üç farklı düşünce akımı olan liberalizm, eleştirel sosyalizm ve Yeni Konfüçyüsçülüğe mensup Çinli aydınların mevcut sistemin meşruiyeti ve demokrasi kavramı üzerine yaptıkları tartışmaları ele almaktadır. Böylelikle çalışma, Çin entelijansiyasının ülkelerinin üç bin yıllık fikir dünyasından ve yönetim deneyiminden yararlanarak geliştirdikleri demokrasi ve meşruiyet kavramlarını inceleyerek Çin’in sahip olduğu canlı siyasi ve entelektüel tartışma ortamını gözler önüne sermeyi amaçlamaktadır. Diğer bir deyişle çalışma, günümüz Çin’inde aydın sınıfının tek parti sistemine boyun eğmek yerine bu sistemi olumlu ve olumsuz yönleri ile hararetli bir biçimde, zaman zaman rejime karşı çıkan fikirler geliştirerek tartıştığını ortaya koymaktadır. Ne var ki bu tartışmalarda öne sürülen fikirler ancak ÇKP’nin izin verdiği ölçüde etkili olabilmekte, öne çıkarılan fikirler de Parti tarafından hem rejimin hem de politikaların meşruiyetini sağlamakta kullanılmaktadır. Başka bir deyişle Çinli entelektüeller, farklı görüşler öne sürerek bilgi üretimine katkıda bulunsalar da bu fikirlerin politika yapım süreçleri üzerindeki etkisi Çin Komünist Partisi tarafından belirlenmektedir., In the post-Mao Zedong period, especially during the 1990’s following the 1989 Tiananmen events, a Renaissance took place in the Chinese world of thought. During this period, new currents of thought such as liberalism, critical socialism, Neo-Confucianism and nationalism emerged and spread rapidly among Chinese intellectuals, while the relationship between the state and the Communist Party of China (CPC) and Chinese intellectuals underwent a major transformation. In this process, the CPC’s Maoist era dominance over the production of knowledge has significantly weakened. Today, although the state and the Party have not completely lost their ability to control knowledge production and the intelligentsia, they must be content with steering them. In the academic literature, the People's Republic of China is mainly treated as an authoritarian single-party system. This leads to the ignorance of polyphony in Chinese domestic politics and intellectual knowledge production and creates the perception that the country is monodic in domestic political issues. However, since the 1990s, Chinese intellectuals have been in an intense debate about the country's economic, political and social issues. On the one hand, Chinese intellectuals, who are members of currents of thought that have different approaches to the world order and the Chinese administrative system, are in a struggle with other intellectuals to control knowledge production and influence the decision-making mechanisms of the state. On the other hand, each group of intellectuals also have diversity of views and are engaged in a debate. This study discusses the liveliness of Chinese intellectual production by analyzing the discussions among the Chinese intellectuals from three different currents of thought, namely liberalism, critical socialism and New Confucianism, on the legitimacy of the current system and the concept of democracy. In this way, by addressing the concepts of democracy and legitimacy that the Chinese intelligentsia has developed by taking advantage of the three thousand years of intellectual world and management experience of their countries, the study aims to reveal the country’s lively political and intellectual debate environment. In other words, the study reveals that in today's China, instead of submitting to the single-party system, the intellectual class fervently discusses this system with its positive and negative aspects, by, from time to time, developing ideas that even oppose the regime itself. However, the ideas that stand out in the discussions can only be influential to the extent permitted by the Communist Party of China and are used by it to ensure the legitimacy of both the regime and the policies pursued. In other words, even though Chinese intellectuals contribute to knowledge production by mooting different ideas, the impact of these ideas on policy-making processes is determined by the CPC.

Pseudoaneurysm ,Case report ,Right ventricle ,Catheterization - Abstract
BackgroundRight ventricular pseudoaneurysm is an extremely rare finding than left ventricular pseudoaneurysm, associated with high mortality. The diagnosis of right ventricle pseudoaneurysm is often challenging because of its rarity and lack of typical clinical features. However, advanced cardiac imaging techniques including CT angiogram and MRI can help a timely diagnosis to avoid a fatal outcome.Case presentationThe authors present the imaging findings of a right ventricular pseudoaneurysm in a 33-year-old male, presented with dyspnea and chest pain after exertion for 2weeks. The gated CT and cardiac MRI showed a small outpouching from the right ventricle apex into the pericardial space, consistent with a pseudoaneurysm. He underwent cardiac surgery and pseudoaneurysm resection with a favorable outcome.ConclusionRight ventricular pseudoaneurysm is a very rare complication following right heart catheterization and a potentially life-threatening condition that requires prompt diagnosis and management. Though the lack of its typical clinical presentation is often a diagnostic challenge, advanced cardiac imaging techniques including CT angiogram and MRI may help a timely diagnosis to avoid a fatal outcome.

Traffic density is one of the most important parameters to consider in road construction. The presence of different components in road construction makes it essential to know the individual layer and inter-layer behaviors. One of the physical factors that plays a major role in these layers is their displacement, which varies depending on the type and engineering properties of these layers. Road damaging is inevitable as different deformations also trigger mismatching. Due to incompatibilities between layers, the number and content of repairs are also high than they should be, which increase maintenance costs. Therefore, it is important to conduct experimental and theoretical studies on this subject. Although the effect of traffic density on a single layer has been studied, there are not many studies investigating the co-movement of different layers. Therefore, the aim of this paper is to provide a holistic approach to this subject by compiling different studies. No sponsor

Amaç: Kovaryans analizi (ANCOVA), bir çalışmada etkisi incelenen faktör dışında bağımlı değişken ile ilişkisi bulunan sürekli bir veya birden fazla değişkenin etkisinin istatistiksel olarak kontrol edilmesini sağlayan bir yöntemdir. Bu çalışmada randomize olan araştırmalarda ortak değişken ile sonuç değişkeni arasında korelasyon bulunan modellerde ortak değişkenin etkisinin göz ardı edildiği varyans analizi (ANOVA) ile ortak değişken etkisinin arıtıldığı ANCOVA’nın korelasyon düzeyine bağlı olarak gücünün değişimi karşılaştırılmıştır. Gereç ve Yöntemler: Araştırmamızda Cohen’in küçük, orta ve büyük f etki büyüklüklerine bağlı 3 farklı senaryo kullanılarak n=30, 50 ve 100 örneklem büyüklükleri için benzetim çalışması yapılmıştır. Her bir benzetimde bağımlı değişken ile ortak değişken arasında 0’dan 1’e kadar 0,1 birimlik artış ile 11 farklı korelasyon bulunacak şekilde veri seti üretilerek her senaryoda 5000 benzetim yapılmıştır. Benzetim uygulamaları için R paket programı kullanılmıştır. R paketinde veri üretmek için “MBESS” ve güç hesaplamaları için “pwr” açık kaynak kodlu kütüphaneler kullanılmıştır. Bulgular: Küçük ve orta etki büyüklüklerine sahip benzetim sonuçlarında sonuç değişkeni ile ortak değişken arasında 0,20 korelasyon bulunduğunda ANOVA ile ANCOVA arasındaki güç değerinin ayrışmaya başladığı ve korelasyon değeri 0,50 ve sonrasında ANCOVA’nın ANOVA’ya göre çok daha fazla güce ulaştığı görülmüştür. Sonuç: Ortak değişken ile sonuç değişkeni arasında 0,2 ve üzeri korelasyon bulunduğunda ANOVA yerine ANCOVA kullanılarak daha az sayıda örneklem büyüklüğü ile araştırmada yeterli güce ulaşılacaktır. Objective: Covariance analysis (ANCOVA) is a statistical procedure that enables one to compare groups on some quantitative dependent variable while simultaneously controlling for the effects of selected other continuous variables, which co-vary with the dependent. The control variables are called the “covariates”. In this study, we aimed to compare the statistical power of variance analysis (ANOVA), in which covariate was omitted, and ANCOVA for different values of the correlation r between the covariate and the dependent variable in randomized studies. Material and Methods: In our study, a simulation was conducted for n = 30, 50 and 100 sample sizes by using 3 different scenarios of Cohen’s small, medium and large f effect sizes. In each simulation, a data set was generated with 11 different correlations from 0 to 1 with an increase of 0.1 units between the dependent variable and the covariate, and 5000 simulations were made in each scenario. R package was used for simulation applications. The “MBESS” open source library was used to generate data and the “pwr” library was used for power analysis in the R package. Results: The results of simulation for small and medium effect sizes, showed that statistical power for ANOVA and ANCOVA started to decompose when the covariate-dependent variable correlation was higher than 0.2. ANCOVA reached much more statistical power than ANOVA when covariate-dependent variable correlation was higher than 0.5. Conclusion: The use of ANCOVA instead of ANOVA may considerably reduce the number of patients required when the covariate-dependent variable correlation was higher than 0.2.

Amaç: Bu araştırmada, tanı doğruluğu çalışmalarının raporlama kalitesini iyileştirmek ve bir standart oluşturmak amacıyla 2003 yılında yayınlanan ve uluslararası birçok yayıncı tarafından makale yüklerken doldurulması zorunlu hale getirilen 25 maddelik STARD (the standards for the reporting of diagnostic accuracy studies) kriterlerinin 2015 yılında güncellenmiş 30 maddelik yeni versiyonunun Türkçeye uyarlanması amaçlanmıştır. Araştırmanın, Türkçe yayınlanan tanı doğruluğu çalışmaları için standart oluşturulması yoluyla yayın kalitelerinin arttırılmasına katkı sağlayacağı düşünülmektedir. Gereç ve Yöntemler: STARD 2015 kriterleri, üç yazar tarafından birbirlerinden bağımsız olarak Türkçeye çevrilmiş ve YY’nin liderliğinde her bir madde için görüş birliği sağlanarak son hali verilmiştir. Türkçeye uyarlanmış kontrol listesinin tekrar edilebilirlik düzeyini değerlendirmek amacı ile iki akademisyen hekim 15 tanı doğruluğu çalışmasının kalitelerini değerlendirmiştir. Değerlendiriciler arasındaki uyum için GWET AC1 istatistiği, Sınıf İçi Korelasyon Katsayısı (SKK) ve Bland-Altman yöntemleri kullanılmıştır. Bulgular: GWET AC1 istatistiğine göre 21 kriterin değerlendirme sonuçları arasında tam uyuşma olduğu, 8 kriterin 0,81-1,00 aralığında, 5 kriterin 0,61-0,80 aralığında olduğu gözlenmiştir. Hekimlerin makalelere vermiş oldukları toplam puanlar arasında SKK değeri 0,871 (%95 GA: 0,616-0,957) olarak bulunmuştur. Sonuç: Birçok uluslararası yayıncı tarafından makale yüklerken doldurulması zorunlu hale gelen STARD 2015 kılavuzunun ülkemizdeki dergilerde tanı doğruluğu ile ilgili çalışmalarda kalitenin arttırılması için zorunlu bir kılavuz haline gelmesi yakın gelecekte öngörülmektedir. Objective: This study aims to perform Turkish adaptation of the 30-item new version of the 25-item STARD criteria updated in 2015, which was originally published in 2003 and had to be filled in many international journals while submitting an article with a view to improving the quality of reporting in diagnosis accuracy studies and forming a standard. The study is believed to contribute to the improvements in publication quality of the Turkish publications by forming a standard for diagnosis accuracy. Material and Methods: STARD 2015 criteria were translated to Turkish by three authors separately, and a consensus was reached by giving the final version of each item with YY’s guidance. Two doctors who are academicians checked the quality of the 15 diagnosis accuracy draft with a view to evaluating its repeatability level. Agreement among the raters was checked using GWET AC1, Intraclass Correlation Coefficient (ICC) and Bland-Altman methods. Results: GWET AC1 statistics showed that there was a full match between the evaluation results of the 21 criteria. Eight criteria were between 0.81 and 1.00 and 5 criteria were between 0.61 and 0.80. ICC value was found to be 0.871 in the total scores given to the articles by the doctors. Conclusion: It is predicted that in the near future it will be obligatory to fill in the STARD 2015 guide, which became obligatory in many international journals while submitting an article, with a view to increasing the quality of the studies on diagnosis accuracy in the journals in our country.

Amaç: Çalışmada düşük akım anestezi uygulamasında vücut ısısının daha iyi korunması nedeniyle intra-operatif kas gevşetici ihtiyacında bir artış olup olmayacağının belirlenmesi amaçlanmıştır. Bu amaçla çalışmada minimal, düşük ve orta akım hızlı anestezi uygulamalarının intra-operatif kas gevşetici tüketimine olan etkileri incelendi. Gereç ve Yöntem: Çalışmaya ASA I-III, ortalama 90-120 dakika süreli genel anestezi altında elektif şartlarda opere olacak 18-75 yaş arası 120 hasta dahil edildi. Hastalar randomize olarak minimal akım (n=40, taze gaz akımı 0,5 L/dk), düşük akım (n=40, taze gaz akımı 1 L/dk) ve orta akım (n=40, taze gaz akımı 2 L/dk) olarak üç gruba ayrıldı. Nazofaringeal vücut sıcaklığı, kalp hızı, periferik oksijen satürasyonu, sistolik arteriyel basınç, diyastolik arteriyel basınç, ortalama arter basıncı ve indüksiyon sonrası; 1., 5., 10., 15., 30. ve sonrasında 30 dakikada bir; inspire edilen anestezik ajan fraksiyonu (FiSevo), ekspire edilen anestezik ajan fraksiyonu (FeSevo), inspire edilen oksijen fraksiyonu (FiO2 ), inspire edilen karbondioksit fraksiyonu (FiCO2 ), minimum alveolar konsantrasyon değerleri ve end-tidal karbondioksit değeri (EtCO2 ) indüksiyon sonrası 5., 10., 15., 30. ve sonrasında 30 dakikada bir kayıt edildi. Bulgular: Gruplar arasında entübasyona geçme süreleri (train of four: TOF 0) benzerdi (p=0,727). Minimal akım için 106,12±38,94, düşük akım için 110,87±38,04, orta akım için 104,45±34,80 saniyede geçilmiştir. Birinci ek doz uygulama zamanı (TOF 25) gruplar arasında benzerdi (p=0,476). İkinci ek doz uygulama zamanı (ikinci kez TOF 25) gruplar arasında benzerdi (p=0,317). Akım gruplarına göre 1. ve 2. ek doz kas gevşetici miktarları arasında anlamlı fark yoktu (sırasıyla; p=0,170, p=0,214). Sonuç: Minimal akım anestezisinin rokuronyum ile oluşturulan nöromüsküler blokajda kas gevşetici tüketimini arttırıcı etkisinin olduğu ancak bu etkinin sınırlı bir etki olduğu düşünülmektedir. Minimal akımlı anestezi, ameliyathane havasının temiz kalmasını sağlamakta, operasyon maliyetini azaltmakta ve solunum devresindeki nem ve sıcaklık değerlerini yükseltmektedir. İntra-operatif daha iyi fizyolojik solunum şartları sağlaması ve intra-operatif hipotermiyi azaltması nedeniyle teşvik edilmesi gereken bir anestezi yöntemidir. Objectives: The aim of this study was to determine whether there would be an increase in the need for intra-operative neuromuscular blocker consumption due to better preservation of body temperature in low flow anesthesia. In this study, the effects of minimal, low and medium flow anesthesia on intra-operative neuromuscular blocker consumption were investigated. Materials and Methods: The study involved 120 patients aged between 18 and 75 who would have an operation in elective conditions under general anesthesia for approximately 90 to 120 minutes ASA I-III. The patients were randomly divided into three groups as minimal flow (n=40), low flow (n=40), and medium flow (n=40). Nasopharyngeal body heat, heart rate, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, and peripheral oxygen saturation were recorded in the 1st, 5th, 10th, 15th, and 30th minute after induction and in every 30 minute later; FiSevo, FeSevo, FiO2 , FCO2 , minimum alveolar concentration values and EtCO2 were recorded in the 5th, 10th, 15th, and 30th minute after induction and in every 30 minute later. Results: The time of intubation was similar between the groups (p=0.727: minimal flow=106.12±38.94, low flow=110.87±38.04, medium flow=104.45±34.80 seconds). The time of the first additional dose was similar between the groups (p=0.476). The time of the second additional dose was similar (p=0.317). No significant differences were found between the groups in terms of the 1st and 2nd additional dose neuromuscular blockers amount (p=0.170, p=0.214). Conclusion: Minimal flow anesthesia is considered to have an effect on the increase in the use of neuromuscular blockers formed by rocuronium, yet this effect is considered to be limited. Minimal flow anesthesia ensures that operating room air remains clean, reduces operating costs and increases humidity and temperature in the breathing circuit. It is an anesthetic method that should be encouraged because it provides better physiological respiratory conditions and reduces intraoperative hypothermia.

Amaç: Akut lösemi/lenfoma ve myeloid sarkom, hematopoietik prekürsör hücrelerden gelişen klonal neoplastik proliferasyonlardır. Bu çalışmada, olgularının epidemiyolojik analizlerinin yapılması, global sonuçlarla karşılaştırılarak değerlendirilmesi amaçlanmıştır.Gereç ve Yöntem: Ege Üniversitesi Kanserle Savaş Araştırma ve Uygulama Merkezi veri tabanına kayıtlı, 1992-2017 yıllarında akut lösemi/lenfoma ve myeloid sarkom tanısı alan 2.046 erişkin olgu retrospektif olarak değerlendirilmiştir. Bulgular: Olguların %58’i erkek olup; ortalama tanı yaşı 50,62, medyan tanı yaşı ise 52 idi. En sık (%62,5) akut myeloid lösemi (AML) izlendi. Olguların %95,8’i lösemik prezentasyon göstermekteydi. Sınıflandırılamayan lenfoblastik lösemi (ALL) olguları yıllara göre azalırken, diğer gruplarda yıllara göre lösemi tanısında artış dikkatimizi çekti. Çocukluk yaş grubunda daha sık karşımıza çıkan ALL olgularında yaş arttıkça görülme oranlarının azaldığı, hücre dizisi belirsiz akut lösemi olgularında ise yaş arttıkça görülme oranlarının da arttığı saptandı. AML ve tüm lösemi olguları ise en çok 40-64 yaş aralığında yer almaktaydı. Akut lösemi olgularında 1, 5, 10 ve 25 yıllık sağkalım sırasıyla %55,7, %29, %23 ve %15 olarak bulundu. Ayrıca sağkalım 18-39 yaş grubunda %52,3, 40-64 yaş grubunda %35,3, 65 yaş ve üstü grupta %20,9 idi.Sonuç: Cinsiyet ve sağkalım arasında bir fark saptanmaz iken, lösemik prezentasyon gösterenlerde, tedavi almayan olgularda ve yaş arttıkça sağkalım daha kısa bulunmuş ve istatistiksel olarak da anlamlı saptanmıştır. Prognozda, histolojik tip, yaş ve tedavi bizim çalışmamızda da öne çıkan önemli parametrelerdendir., Aim: Acute leukemia/lymphoma and myeloid sarcoma originated from hematopoietic precursor cells are clonal neoplastic proliferations. The aim of this study was to evaluate the epidemiological analysis of patients and compare them to global findings.Materials and Methods: The data, including 2,046 adult patients diagnosed as acute leukemia/lymphoma, and myeloid sarcoma recorded at Ege University Cancer Control and Research Center, within 1992-2017, were evaluated retrospectively.Results: Of the patients, 58% was male; the mean age was 50.62, the median age was 52. The most common type of leukemia (62.5%) was acute myeloid leukemia (AML). Leukemic presentation was seen in 95.8% of the patients. While the non-specified type of lymphoblastic leukemia (ALL) decreased in years, the diagnosis of leukemia in other groups increased in years. It was found that the incidence of ALL, which are more common in the pediatric age, decreased with age, and the incidence of acute leukemia with ambiguous lineage increased with age. Most of the AML and all leukemia patients were in the age range of 40-64. Overall survival for 1, 5, 10, and 25-year in patients with acute leukemia were 55.7%, 29%, 23%, and 15%, respectively. In addition, it was 52.3% in the 18-39 age range, 35.3% in the 40-64 age range, and 20.9% in the 65 age and over.Conclusion: While there was no significant difference between gender and survival, leukemic presentation, untreatment and older age was statistically significantly correlated with poor overall survival. Histologic type, age, and treatment of the disease were found to be among the most important prognostic parameters in our study.
