Information services gained a new dimension as a result of the rapid developments in information technologies and Internet. As a consequence of the developments in communication and cooperation facilities in the electronic environment, getting access to information quickly has become the main objective of information services. Hence, theses that fulfil an important function in the provision of information services in general have gained a new dimension as well: theses that are accessible full-text through Internet have been used in a much more effective way. In order for theses to be made accessible more effectively via Internet in Turkey, the components such as infrastructure, storage, archiving, access management and indexing should be studied. In this article, in three steps, the overall process from preparation of the theses in electronic environments to the submission of them to library, from indexing and archiving of theses at the library to making their full-texts available to users via Internet
Assessment of the quality and reliability of the information on lateral epicondylitis surgery on YouTube
Aim: To investigate the quality and reliability of videos related to lateral epicondylitis (LE) surgery on YouTube® and to define a new scoring system that can be used to assess online information about LE.
Method: To conduct the study, a search on YouTube® using the words "lateral epicondylitis surgery" and "tennis elbow surgery" was conducted on February 15, 2022. The first 100 videos that appeared upon the search were included in the study. The videos were classified based on the type of publishing source as a medical doctor, medical center, and Commercial/Medical media agency. Two authors independently analyzed the videos. The quality and reliability of the videos were examined using DISCERN score, Journal of the American Medical Association (JAMA) score, Health on the Net (HON) score, and a novel YouTube® LE-score (LES). Video Power Index (VPI) and View Ratio (VR) were used to assess the popularity of videos.
Results: A total of 29 videos were included in the study. There was no significant difference between the groups in terms of DISCERN, JAMA, HON, and LES scores. Although the group of medical doctors had much higher VRs and VPIs, there was no significant difference between the groups. LES score was found to be positively correlated with DISCERN, JAMA and HON (rho 0.879, p< 0.001; rho 0.709, p < 0.001; rho, 0.838, p < 0.001, respectively).
Conclusion: The quality and reliability of the online information made available by YouTube® concerning LE surgery had an average level of quality and reliability. In addition, the LES scoring system created by us was highly compatible with the DISCERN and JAMA scoring systems accepted in the literature. It can be used as evaluation scoring in searches about lateral epicondylitis
Examination of game addiction studies conducted in Turkey: A systematic review study
The aim of this study is to examine the methodological orientations in game addiction studies in Turkey between 2019 and 2022 in a holistic way and to present suggestions for new literature studies. For this purpose, only articles written in Turkish language were reviewed on Google Scholar. Open-access quantitative studies between 2019 and 2022 were included in our study. As a result, 69 out of 257 studies were found to comply with the predetermined criteria. The number of participants in these 69 studies, with a total sample size of 26,415, varies between 60 and 987. Almost half of the studies sample group is children (n = 36). The majority of the studies examine the relationship between academic achievement, familial and social relationship problems, gaming behavior and game addiction in children and adolescents. It was found that gaming addiction was higher in male students compared to female students, especially between the ages of 14-15. Among children, male students play digital games more than girls, and they mostly prefer action-adventure, war, and racing games. Previous studies have concluded that the use of consoles and smartphones in adolescents and young adults has a high impact on digital game addiction. In the light of the findings, it is suggested that empirical studies on game addiction should be addressed with different aspects using new literature studies

Analysis of The Factors Affecting The Capital Structure of Oil Exploration And Production Companies: Comparative Analysis of TP And The Five Major Oil Exploration And Production Companies in The World
Oil and gas companies are still the most powerful and profitable companies in the
world. Knowing the factors that affect the preferences for forming a capital structure of
such a critical sector will provide a substantial contribution to the field of capital
structur theory which is understated in thef literature. Besides, determining capital
structure composition and financing decisions of the oil and gas companies are
important issues for national and international investors who are considering to invest in
the oil and gas sector, for suppliers providing services to the sector and for banks
providing funds to the sector. In this context, for analyzing the factors affecting the
capital structures of EXXONMOBIL, BP, SHELL, PETROBRAS, LUKOIL and
Turkish Petroleum (TP), linear regression and panel data regression analysis are
perfomed by using the data of these companies for the years 2006-2014 (covering 36
quarter period). Empirical results revealed that capex, operating profit, risk and quick
ratio have negative relation with leverage, whereas operating net cashflow-growth
opportunities-size (all together forming an independent variable) has positive relation
with leverage. Additionally, our empirical results mostly support the pecking order
theory
Alienation and anger relation in educational organizations (Şişli Technical and Industrıal VHS)Eğitim örgütlerinde yabancılaşma ve öfke ilişkisi (Şişli Teknik ve EML)
This research aimed to determine the correlation of anger and alienation in educational organizations on the basis of perceptions of teachers. Data was collected from 146 teachers who worked in Şişli Vocational High School, İstanbul. The research was a correlational study which had a quality of relationship survey model. In order to collect the data necessary for the research, 'The work alienation scale ' by Elma ( 2003) and 'The scale of constant anger and anger expressions styles' which was prepared by Spielberger (1998) and translated and adapted by Ozer ( 1994) were conducted. The research results indicated that there was meaningful, medium level, positive sided correlation between the dimensions of work alienation and constant anger level with the dimensions of inward anger among the teachers. It was also found that there was meaningful, positive sided, low level correlation between the dimensions of work alienation and constant anger management level. However, there was not found any meaningful correlation between the dimensions of outward anger and work alienation. Besides, the research results showed that teachers feel alienation mostly in terms of school alienation and from the anger expression styles, they used anger control most frequently. ÖzetBu çalışmanın amacı; öğretmenlerin işe yabancılaşma düzeyleri ile sürekli öfke ve öfke ifade tarzları arasında anlamlı bir ilişki olup olmadığını tespit etmektir. Şişli Teknik ve Endüstri Meslek Lisesi’nde görev yapan 146 öğretmen üzerinde yapılan araştırma, nicel verilere dayalı, ilişkisel tarama modeli niteliğinde, korelasyonel bir çalışmadır. Araştırmada Elma (2003) tarafından hazırlanan “Öğretmen İşe Yabancılaşma Ölçeği” ve Spielberger (1988) tarafından geliştirilip, Özer (1994) tarafından çevirisi ve uyarlaması yapılan “Sürekli Öfke ve Öfke İfade Tarzı Ölçeği” kullanılmıştır. Araştırma sonucunda; öğretmenlerde, işe yabancılaşma ile sürekli öfke düzeyi ve öfke içte alt boyutu arasında, orta düzeyde, pozitif yönlü, anlamlı ilişki tespit edilmiştir. İşe yabancılaşma ile öfke kontrol alt boyutu arasında düşük düzeyde, pozitif yönlü, anlamlı ilişki tespit edilmiş, öfke dışta alt boyutu arasında ise anlamlı ilişki tespit edilememiştir. Ayrıca, öğretmenlerin yabancılaşma duygusunu, en çok okula yabancılaşma boyutunda yaşadığı ve öfke ifade tarzlarından, en sık öfke kontrolünü kullandıkları tespit edilmiştir

Trakya Bölgesinde Organik Şaraplık Üzüm Yetiştiriciliği ve Şarap Yapımı
Dünyada geniş alanlarda uygulanan klasik tarımın giderek doğal dengeyi bozması sonucu örgütlenen üreticiler doğayı tahrip etmeyen, insan sağlığında yan etki yapmayan tarımsal ürünleri tercih etmeye başlamışlardır. AB ve FAO tarafından da klasik üretime alternatif olacak tarzda ortaya çıkan bu üretim şekli ekolojik veya organik tarım olarak isimlendirilmektedir.
Ülkemizde 1985 yılında başlayan organik tarım ürünleri üretimi 2000’li yıllarda Dünya organik tarım pazarlarına talep yaratma çabaları ile yen bir boyut kazanmıştır.1999 yılında 92 tarım ürünü organik olarak üretilmiş olup bu üretimde üzümün payı 7182 ton’dur.
Pestisit kalıntısı bulunmayan çevre dostu ürünlere, şarap sektörü de ilgi duymuş ve ekolojik şarapçılık gündeme gelmiştir.
Ülkemizde şaraplık üzüm üretiminde büyük bir paya sahip Trakya Bölgesinde ekolojik ürün sertifikasyonuna sahip bağlar ve bu bağlardan elde edilen üzümlerden uygun yöntemlerle ekolojik şarap elde edilmesi için Enstitümüz tarafından proje bazında çalışmalar başlatılmıştır. Böyle çalışmaların üretici koşullarında ve çiftlik sistemleri araştırmaları kapsamında yürütülmesinin gerçekçi sonuçlar ortaya koyacağı düşünülmektedir
