Item The Inventory of Flood Disasters in Turkey(2022) Gurer, Ibrahim; Ucar, IbrahimTurkey is located both Europe and Asia, and covers an area of 780 580 km(2) including the lakes. Turkey undergoes different types of natural disasters because of its geographical location, geomorphology, and topography. Flooding is the second important natural hazard after earthquakes. A flood inventory of the period extending from 1955 to 2020 having a total of about 3250 events was prepared using a simple computer program based on Excel for easy access to different geomorphologic parameters such as surface areas of river basins, slope, geological structure, vegetative cover, type of precipitation, and the elevation above mean sea level (a.m.s.l) and hydro-meteorological parameters. In the same inventory each flood has been defined with damages on human as lost and injured, size of flooded area and loss of wealth (not exact information for wealth). By categorization of the available data in hand, spatial and time distributions of past flood events were determined. In large basins, negative impacts are more closely related to climatic factors, but in small watersheds, the urbanization along the rivers, internal migration, regional planning, urban drainage infrastructure are more important on negative impacts. In order to prevent the floods and minimize the adverse effects to property, both structural and non-structural solutions are applied in Turkey. Two case studies added to show the solutions.Item Hydropower Outlook of Turkey in 2021(2022) Gurer, IbrahimTurkey is located partly on Europe and also on Asia, and has a surface area of 780 580 km(2) and a population of 84.6 million and electric energy is essential for the everyday life. The annual per capita consumption of electricity is mainly used to measure the prosperity of a nation. The energy use in a country increases not only with population increase but also by improving the living standards of people and industrial development. Turkey being a non-oil-producing country at present, therefore needs to import fossil fuels (like natural gas and fuel oil) as the main source of electric energy. The utilization of fossil fuels for energy production by thermal power plants is one of the main sources of air pollution. The consumption of imported energy sources should be reduced for the environmental, economic, and political reasons. As the electricity need of the country is increasing continuously, more energy from the renewables and national resources must be produced. Hydropower plants (HPPs) provide clean, fast, flexible electricity generation. The amount of electricity that aHPP can produce basically depends on the available flow rate (Q) and the head (H). Very briefly the greater the flow rate and the net head, the more electricity can be produced in a HPP. The first hydropower station of Turkey had been opened at Tarsus town in 1929. Number of hydropower installations and total installed capacity has increased especially after the 1960s. In 2020, the Turkish electric production values were 32.9% from HPPs, 27.2% from thermal plants working with natural gas, 21.3% from thermal plants working with coal, 8.8% fromwind power plants, 6.8% from the sun, 1.6% from geothermal plants, and about 1.4% from other types of sources. Technically and economically feasible total hydroelectric energy potential of Turkey is 180 billion kWh/year, of which 160 billion kWh/year has been developed and completed. With 714 completed facilities and 31,391 MW installed power and 108.0 billion kWh/year of it has been put into operation. With the projects to be established until 2023, a total installed power capacity of 40,000 MW and a generation potential of 135 billion kWh/year will be reached. Because of the very fast increase in energy consumption, and only 22% of total energy is produced from national sources, and 125 billion dollars total investment is needed. Due to the climate change, and the change in the oil prices, the renewable sources such as solar, wind, geothermal, biogas, biomass, hydropower etc. should be developed and put in service as quickly and efficiently as possible. In this paper, the current level of hydropower production and energy saving, and power consumption by different sectors, and the subject matter of the most recent energy figures are given and the future projections are also presented.Item Academic Trends in European Union Studies in Turkey within the Framework of Turkey-EU Relations(2022) Mercan, S. Sezgin; Bilgin, Kivilcim Romya; Karadag, Haluk; Ongun, YeldaThe relationship between academics and policymakers has a complex and multi-layered structure, and there are different views on how this relationship should be. While discussing the political processes in the context of Turkey's membership, the interactions between academics and policymakers in the relations between Turkey and the EU have the potential to provide solutions in the steps that need to be taken. However, the academic tendency of EU studies in Turkey will be revealed by answering questions such as what subjects are preferred by academics working on the EU in Turkey to study in the knowledge-production process, which subjects they prioritize in EU studies, what the effects of the ups and downs in Turkey-EU relations are on the academy, and how the academy positions itself in the field of EU studies. It is considered that such a study will contribute to further studies on how the academy's relations with policymakers are and how they should be in studying Turkey-EU relations.Item Protective Motivators and Precautionary Behaviors Against COVID-19 in Turkey(2023) Turen, Ufuk; Gokmen, Yunus; Erdem, Haluk; Kalkin, Gokdeniz; 35394534In this research, we investigated the protection motivators and precautionary behaviors against coronavirus disease 2019 (COVID-19) and the associations between them. To do this, we developed two original scales, collected data (2783 responses) using an online survey, after removing the responses (319), which were filled in incompletely or incorrectly in the questionnaire, we obtained 2464 participants covering the aged 18+ population in Turkey. Based on random sampling, our sample complies with these ratios and generally reflects the aged 18+ population of Turkey. We confirmed the psychometrical validity and reliability of our two scales using the collected data. Herewith, we found that perceived susceptibility of COVID-19 infection is very high, perceived severity of COVID-19 is medium, COVID-19 related information seeking is high, beliefs on precautions' efficacy is high and also the practice of precautionary behaviors is high. Our research depicts that all protection motivators significantly are related with the practice of precautionary behaviors (routine and leisure). However, with the only exception of perceived severity of COVID-19 is not related with precautionary behaviors (routine). Besides, we saw that females' average in all variables is significantly higher than males and some variables are sensitive to age, education level, marital status and the number of children. We believe that the findings provide essential inputs for authorities in establishing public health policies against the present pandemic and likely ones in the future.Item The Privacy Consciousness of Undergraduate Students: Comparison Between Turkey and Japan(2022) Ozturk, Deniz; Eyuboglu, Gulcan; Baykara, Zehra Gocmen; Tabata, Naoya; Sato, Hirotsune; 36106807AIM: This study was designed to compare the privacy consciousness of undergraduate students in Turkey and Japan.METHOD: A comparative cross-sectional study was carried out. First-year undergraduate students at a university in Turkey (n = 235) and a university in Japan (n = 242) voluntarily participated in the study. Data were collected via a web-based structured questionnaire, using the Descriptive Characteristics Form and the Privacy Consciousness Scale, between November and December 2020. Written approval was obtained from the universities and the ethics board. Written informed consent was obtained from all participants. RESULTS: The privacy consciousness of the Turkish students was significantly higher than that of the Japanese students (p < .05).CONCLUSION: Privacy consciousness can be affected by individual, social, and cultural value differences, beliefs, and perceptions. It is suggested that similar studies be conducted with a greater number of samples and between different countries.Item Economic Burden of Severe Asthma in Turkey: A Cost of Illness Study from Payer Perspective(2021) Bavbek, S.; Malhan, S.; Mungan, D.; Misirligil, Z.; Erdinc, M.; Gemicioglu, B.; Oguzulgen, I. Kivilcim; Oksuz, E.; Yildiz, F.; Yorgancioglu, A.; 0000-0002-5723-5965; 32372589; K-8238-2012Objective. To estimate economic burden of severe asthma in Turkey from payer perspective based on expert panel opinion on practice patterns in clinical practice. Methods. This cost of illness study was based on identification of per patient annual direct medical costs for the management of severe asthma in Take, from payer perspective. Average per patient direct medical cost was calculated based on cost items related to outpatient visits laboratory and radiological tests, hospitalizations and interventions drug treatment and equipment, and co-morbidities/complications. Results. Based on total annual per patient costs calculated for outpatient admission ($177.91), laboratory and radiological tests ($ 8232), hospitalization/interventions ($1,154.55), drug treatment/equipment ($2,289.63) and co-morbidities ($ 661.39) cost items, total per patient annual direct medical cost related to management of severe asthma was calculated to be $ 4,369.76 from payer perspective. Drug treatment/equipment (524%) was the main cost driver in the management of severe asthma in Turkey, as followed by hospitalizations/interventions (264%) and co-morbidities (15.2%). Conclusions. In conclusion, our findings indicate that managing patients with severe asthma pose a considerable burden to health economics in Turkey with medications as the main cost driver.Item Unsustainable harvest of water frogs in southern Turkey for the European market(2021) Cicek, Kerim; Ayaz, Dincer; Afsar, Murat; Bayrakci, Yusuf; Peksen, Cigdem Akin; Cumhuriyet, Oguzkan; Ismail, Ilhan Bayram; Yenmis, Melodi; Ustundag, Erdal; Tok, Cemal Varol; Bilgin, C. Can; Akcakaya, H. Resit; ABC-7273-2020Frogs have been harvested from the wild for the last 40 years in Turkey. We analysed the population dynamics of Anatolian water frogs (Pelophylax spp.) in the Seyhan and Ceyhan Deltas during 2013-2015. We marked a total of 13,811 individuals during 3 years, estimated population sizes, simulated the dynamics of a harvested population over 50 years, and collated frog harvest and export statistics from the region and for Turkey as a whole. Our capture estimates indicated a population reduction of c. 20% per year, and our population modelling showed that, if overharvesting continues at current rates, the harvested populations will decline rapidly. Simulations with a model of harvested population dynamics resulted in a risk of extinction of > 90% within 50 years, with extinction likely in c. 2032. Our interviews with harvesters revealed their economic dependence on the frog harvest. However, our results also showed that reducing harvest rates would not only ensure the viability of these frog populations but would also provide a source of income that is sustainable in the long term. Our study provides insights into the position of Turkey in the 'extinction domino' line, in which harvest pressure shifts among countries as frog populations are depleted and harvest bans are effected. We recommend that harvesting of wild frogs should be banned during the mating season, hunting and exporting of frogs < 30 g should be banned, and harvesters should be trained on species knowledge and awareness of regulations.Item Economic Burden Of Lung Cancer In Turkey: A Cost Of Illness Study From Payer Perspective(2021) Cicin, Irfan; Oksuz, Ergun; Karadurmus, Nuri Nuri; Malhan, Simten; Gumus, Mahmut; Yilmaz, Ulku; Cansever, Levent; Cinarka, Halit; Cetinkaya, Erdogan; Kiyik, Murat; Ozet, Ahmet; 0000-0002-5723-5965; 34173876; K-8238-2012Background This study was designed to estimate economic burden of lung cancer in Turkey from payer perspective based on expert panel opinion on practice patterns in clinical practice. Methods In this cost of illness study, direct medical cost was calculated based on cost items related to outpatient visits, laboratory and radiological tests, hospitalizations/interventions, drug treatment, adverse events and metastasis. Indirect cost was calculated based on lost productivity due to early retirement, morbidity and premature death resulting from the illness, the value of lost productivity due to time spent by family caregivers and cost of formal caregivers. Results Cost analysis revealed the total per patient annual direct medical cost for small cell lung cancer to be euro8772), for non-small-cell lung cancer to be euro10,167. Total annual direct medical cost was euro497.9 million, total annual indirect medical cost was euro1.1 billion and total economic burden of lung cancer was euro1.6 billion. Hospitalization/interventions (41%) and indirect costs (68.6%) were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively. Conclusions Our findings indicate per patient direct medical costs of small cell lung cancer and non-small-cell lung cancer to be substantial and comparable, indicating the substantial economic burden of lung cancer in terms of both direct and indirect costs. Our findings indicate that hospitalization/interventions cost item and indirect costs were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively. Our findings emphasize the potential role of improved cancer prevention and early diagnosis strategies, by enabling cost savings related to drug treatment and metastasis management cost items, in sustainability of cancer treatments.Item A test of theory of planned behavior in type II diabetes adherence: The leading role of perceived behavioral control(2021) Dilekler, Ilknur; Dogulu, Canay; Bozo, Ozlem; 0000-0002-5906-3706; C-8140-2014Diabetes mellitus is a health complication that millions of people suffer from all over the world. Type II (non-insulin dependent) diabetes requires many changes in the daily lives of patients, including monitoring blood glucose, following a healthy diet, exercising, and taking medications. Although it is vital for their health, patients generally find it difficult to adhere to their medical regimen. In order to better understand the adherence behaviors of type II diabetes patients, the theory of planned behavior (TPB) was used as the theoretical framework for this study. Ninety type II diabetes patients, who were outpatients of four different hospitals in Ankara, Turkey were administered the TPB tool. The mediation analyses provided support for the mediating role of intention for the attitudes-behavior and subjective norms-behavior relations. The findings did not reveal a mediating role of intention for the PBC-behavior relation but a significant direct effect of PBC on adherence behavior was found. Overall, it seems important that PBC and the multi-faceted nature of adherence behaviors are considered when designing interventions for type II diabetes patients.Item Welcoming immigrants in Istanbul: Gendering faith-based and professionalised hospitality(2021) Senses, Nazli; Farahani, FatanehThis article examines the hospitality practices of pro-migrant civil society organisations in Istanbul. Drawing from qualitative interviews, we focus on intersecting gendered, professionalised and faith-based aspects of pro-migrant activities and explore the ways that politically and morally charged ambivalences of hospitality practices are articulated and negotiated. Moreover, by contextualising Turkey's religious and geopolitical particularity as a gatekeeper of Europe, we work with Derrida's concept of plural laws to investigate hospitality practices towards refugees in Istanbul. Civil actors' intentions and attempts to be good citizens, Muslims, and care providers expose the intimate aspects of hospitality - a segue into discourses of displaced subjects' (gendered) deservingness. By portraying how macro-micro, global-local and public-private relations condition hospitality practices, we observe how globalisation is lived intimately, influencing perceptions of deservingness and the prioritisation of displaced subjects' needs.
