Article Citation - WoS: 3Evaluation of Students' Opinions Regarding Distance Learning Practices in Turkish Universities During the Covid-19 Pandemic(Tuba-turkish Acad Sciences, 2021) Isik, Oguz; Tengilimoglu, Dilaver; Tekin, Perihan Senel; Tosun, Nurperihan; Zekioglu, AysuThe purpose of this study is to identify hether students at Turkish universities are having difficulties in the distance learning process and to reveal their opinions regarding the system. Using a cross-cultural survey design, data were collected from 5052 students. Based on the collected data, 58.5% of the students have asynchronous distance learning classes in their universities. Access to distance learning classes is one of the problems, and it is attributed to computers, internet, and connectivity issues as well as with starting the lessons too early or late. A majority of participants (73.7%) found class materials uploaded by lecturers to distance learning systems to be sufficient or partially sufficient, and 36.7% stated that they had problems accessing resources regarding their homework. Students' satisfaction level with the distance learning system scored 4.4 out of 10. According to the evaluation regarding whether the level of satisfaction of participants varied across the type of university, the satisfaction level of students in public universities is generally low (score of 4.3 out of 10) compared to satisfaction in foundation universities (4.9 out of 10).Article Yapay Zekâ Benimsenmesi ile Marka Sermayesi Arasındaki Karşılıklı Etkileşim: Türkiye Üzerine Ampirik Bir İnceleme(2025) Tengilimoglu, Dilaver; Bas, Mehmet; Dikici, İlkeGünümüzün dijitalleşen iş dünyasında, Yapay Zekâ (YZ) teknolojilerinin benimsenmesi, iç marka yönetimi açısından işletmeler için stratejik bir unsur haline gelmiştir.

If these criteria change, the demand for air transportation will increase. For this purpose, a survey was conducted in the provinces of Kayseri and Bursa, which are among the important trade, industry, and tourism centers in Turkey, in the course of three months between January and March, 2018. Logistic regression, the artificial neural network model, and clustering analyses were applied to the data compiled from questionnaires responded to by 501 individuals in Kayseri and 453 individuals in Bursa. According to the empirical findings, it was concluded that the most significant criteria in the transition to air transportation according to all three methods are the cost of travel/ticket price and non-stop flight. Additionally, it was observed that the Artificial Neural Networks (ANN) model made more accurate predictions compared to others. This study is important since it compares three different methods for the purpose of criteria determination concerning the choice of transportation modes.Article Mapping the Literature on Thermal Tourism: A Bibliometric and Content Analysis(Conscientia Beam, 2025) Alqaifi, Faten; Tengilimoglu, Dilaver; Aras, Ilknur ArslanThis study explores and maps the existing literature on thermal tourism to provide comprehensive insights and inform future research directions. The research design is based on a bibliometric analysis of 48 documents published between 2013 and 2023 and indexed in the Web of Science database. Data were processed and visualized using Microsoft Excel and Bibliometrix, followed by a content analysis of 42 English-language articles to capture thematic developments in the field. The findings indicate that, despite a temporary decline during the COVID-19 pandemic, publications on thermal tourism have shown strong growth and recovery, with an annual growth rate of 46.65%. The most significant contributions originated from Portugal, China, Spain, Taiwan, Turkey, and Japan, with research disseminated across 37 journals. Four central themes were identified: (1) tourist behaviors and satisfaction, (2) demand and motivations, (3) quality and resource management, and (4) strategic and sustainable development. Among these, tourist behaviors and satisfaction emerged as the most prominent research area, representing 38.10% of the analyzed literature. This paper addresses a gap in the literature by mapping the knowledge landscape in the relatively underexplored field of thermal tourism, highlighting its growth potential and proposing a future research agenda. The practical implications suggest that recognizing these trends and themes can help policymakers, industry stakeholders, and academics develop strategies to enhance sustainable practices and expand opportunities in thermal tourism.Article Citation - WoS: 10Citation - Scopus: 10Convergence of Economic Growth and Health Expenditures in Oecd Countries: Evidence From Non-Linear Unit Root Tests(Frontiers Media Sa, 2023) Celik, Esref Ugur; Omay, Tolga; Tengilimoglu, DilaverIntroductionThe relationship between human capital, health spending, and economic growth is frequently neglected in the literature. However, one of the main determinants of human capital is health expenditures, where human capital is one of the driving forces of growth. Consequently, health expenditures affect growth through this link. MethodsIn the study, these findings have been attempted to be empirically tested. Along this axis, health expenditure per qualified worker was chosen as an indicator of health expenditure, and output per qualified worker was chosen as an indicator of economic growth. The variables were treated with the convergence hypothesis. Due to the non-linear nature of the variables, the convergence hypothesis was carried out with non-linear unit root tests. ResultsThe analysis of 22 OECD countries from 1976 to 2020 showed that health expenditure converged for all countries, and there was a significant degree of growth convergence (except for two countries). These findings show that health expenditure convergence has significantly contributed to growth convergence. DiscussionPolicymakers should consider the inclusiveness and effectiveness of health policies while making their economic policies, as health expenditure convergence can significantly impact growth convergence. Further research is needed to understand the mechanisms behind this relationship and identify specific health policies most effective in promoting economic growth.Article Sağlık İşletmelerinin Kurumsal Yönetim ve Sürdürülebilirlik İlkelerine Uyum Düzeyleri Hisse Senetlerinin Fiyat Dalgalanmasını Azaltıyor Mu? Borsa İstanbul Örneği(2025) Tengilimoglu, Dilaver; Sayar, Ali Rıza Zafer; Tümer, TolgaSağlık işletmeleri hem bireylerin sağlığına hem de ülkelerin ekonomilerine çok büyük katkılar sunmaktadır. Sağlık işletmelerinin- diğer tüm işletmeler için de geçerli olduğu üzere- finansal piyasalardan yeterli düzeyde fon toplayabilmesi büyük önem taşımaktadır. Kurumsal yönetim ve sürdürülebilirlik ilkelerine yüksek düzeyde uyumun, yatırımcı talebini ve güvenini artırarak işletmelerin hisse senedi fiyat dalgalanmasını azaltması beklenmektedir. Böylelikle, işletmelerin finansal piyasalardan daha kolay ve daha fazla fon temin edebilmesi mümkün olabilir. Bu çalışmada; Türkiye'de halka açık sağlık işletmelerinin kurumsal yönetim ve sürdürülebilirlik ilkelerine uyum düzeylerinin, hisse senedi fiyat dalgalanması üzerindeki etkisi ampirik olarak araştırılmıştır. Araştırmanın bulguları, sağlık işletmelerinin kurumsal yönetim ilkelerine uyum düzeylerinin hisse senedi fiyat dalgalanmasını azalttığını, ancak bu etkinin istatistiksel olarak anlamlı olmadığını göstermektedir. Ayrıca, sağlık işletmelerinin sürdürülebilirlik ilkelerine uyum düzeylerinin hisse senedi fiyat dalgalanması üzerinde azaltıcı bir etkisi olmadığı sonucuna ulaşılmıştır. Bu durum, kurumsal yönetim ve sürdürülebilirlik alanlarının ve ilgili raporlamaların Türkiye’de hâlen görece yeni olmasıyla açıklanabilir.Article Citation - WoS: 14Citation - Scopus: 14Analysis of Publications on Health Information Management Using the Science Mapping Method: a Holistic Perspective(Mdpi, 2024) Tengilimoglu, Dilaver; Orhan, Fatih; Tekin, Perihan Senel; Younis, MustafaObjective: In the age of digital transformation, there is a need for a sustainable information management vision in health. Understanding the accumulation of health information management (HIM) knowledge from the past to the present and building a new vision to meet this need reveals the importance of understanding the available scientific knowledge. With this research, it is aimed to examine the scientific documents of the last 40 years of HIM literature with a holistic approach using science mapping techniques and to guide future research. Methods: This study used a bibliometric analysis method for science mapping. Co-citation and co-occurrence document analyses were performed on 630 academic publications selected from the Web of Science core collection (WoSCC) database using the keyword "Health Information Management" and inclusion criteria. The analyses were performed using the R-based software Bibliometrix (Version 4.0; K-Synth Srl), Python (Version 3.12.1; The Python Software Foundation), and Microsoft (R) Excel (R) 2016. Results: Co-occurrence analyses revealed the themes of personal health records, clinical coding and data quality, and health information management. The HIM theme consisted of five subthemes: "electronic records", "medical informatics", "e-health and telemedicine", "health education and awareness", and "health information systems (HISs)". As a result of the co-citation analysis, the prominent themes were technology acceptance, standardized clinical coding, the success of HISs, types of electronic records, people with HIM, health informatics used by consumers, e-health, e-mobile health technologies, and countries' frameworks and standards for HISs. Conclusions: This comprehensive bibliometric study shows that structured information can be helpful in understanding research trends in HIM. This study identified critical issues in HIM, identified meaningful themes, and explained the topic from a holistic perspective for all health system actors and stakeholders who want to work in the field of HIM.Article Citation - WoS: 8Citation - Scopus: 9Evaluating the Factors (stress, Anxiety and Depression) Affecting the Mental Health Condition of Nurses During the Covid-19 Pandemic(Sage Publications inc, 2022) Isik, Oguz; Tengilimoglu, Dilaver; Tosun, Nurperihan; Zekioglu, Aysu; Tengilimoglu, OnurThis study aimed to determine the depression, anxiety and stress levels that have negatively impacted nurses' mental health during the COVID-19 pandemic. A sample group of 826 nurses working in Turkey were asked to fill in an online questionnaire in order to evaluate their psychological responses and the related factors that have adversely affected their mental health during the COVID-19 pandemic. In total, 696 nurses (84.3%) showed symptoms of depression, 644 (78%) reported anxiety and 543 (65.74%) reported stress. This study also highlighted that the most concerning factor for the nurses was the risk of transmitting the COVID-19 infection to their household members (89.2%). The most important problems faced by the nurses during COVID-19 included equipment shortages (50.7%), administrative problems (38.5%) and issues such as accommodation and nutrition (27.4%). These were found to have a statistically significant correlation with the nurses' levels of depression, anxiety and stress. The fear of losing a household member, the inability to their household's social needs and the fear of death were among the factors that concerned nurses during the COVID-19 pandemic, significantly affecting their levels of depression, anxiety and stress. Taking the necessary measures to deal with the aforementioned problems and fears is important to protect the health, productivity and efficiency of nurses during the pandemic period.Article Evaluating the Financial Performances of the Publicly Held Healthcare Companies in Crisis Periods in Türkiye(Mdpi, 2023) Tengilimoglu, Dilaver; Tumer, Tolga; Bennett, Russell L.; Younis, Mustafa Z.The purpose of this study was to evaluate the financial performances of the publicly held healthcare companies in crisis periods in Turkiye. The 2018 economic crisis and the COVID-19 pandemic crisis were included in the study as the crisis periods. We collected the financial data of the publicly held healthcare companies and calculated three liquidity, three turnover, three leverage and three profitability ratios through ratio analysis to use as financial performance indicators. We then conducted Wilcoxon signed-rank tests and we performed separate analyses for the 2018 economic crisis and the COVID-19 pandemic crisis. The results of the analyses showed that there were no statistically significant differences between the publicly held healthcare companies' liquidity, turnover, leverage, profitability ratios and thus their financial performances before the crises and after the crises. While the results are reassuring and give valuable insights to managers and policy makers to determine the areas that needs to be strengthened to be better prepared for possible future crises, our sample was limited. Therefore, this study presents an exploratory foundation for future studies which are needed to make a case for financial stability for the publicly held healthcare companies before and after the crisis periods.
