    Determination of obesity, stunting, and nutritional habits in disabled children and adolescents
    (Mattioli 1885, 2018) Kilinc, Fatma Nisanci; Cakir, Biriz; Ekici, Merve; Ozenir, Ciler
    Objective: This study was conducted to determine obesity, stunting and nutritional habits in children and adolescents with disabilities. Methods: The study was carried out in 612 disabled children and adolescents in a 2-19 age group enrolled in 8 special education practice and rehabilitation institutions in Kirikkale city center in Turkey. The general characteristics and eating habits of the participants were examined and body mass indexes (BMI) were calculated (n=527) to determine obesity and stunting. Results: Of the participants (n=612), 39.2% were female and 60.8% were male, of whom 39.4% were mentally disabled, 37.1% were physically disabled, 12.3% were mentally and physically disabled, and 11.3% were suffering other types of disabilities (speech disorders, learning disability, etc.). Of the participants (n=527), 18.8% were overweight and 17.8% were obese. The rate of overweight (Male:18.5%, Female:19.2%) and obesity (Male:19.1%, Female:15.9%) was higher in males compared to females (p>0.05). The correlation between BMI classification and disability type, disability level, and income level was not statistically significant (p>0.05). The rate of stunting was 24.5%, which was lower in males compared to females (Male: 20.4%, Female: 30.8%) (p>0.05). There was no statistically significant difference between height-for-age classifications and the type of disability (p>0.05); however, the difference between disability level and income level was significant (p<0.05). It was observed that 50.0% of the participants had eating problems and 45.5% had the habit of skipping breakfasts. Conclusion: In this study, it was observed that overweight, obesity, and stunting are very high in disabled children and adolescents. This field warrants further research.

    Energy Efficiency of Photovoltaic Cells According to Panel Angles
    (Kırıkkale Üniversitesi, 2024) Kara, Reşit; Ekici, Merve; Yıldırım, Gürcan
    As the need for energy, one of the most important problems today, increases and becomes increasingly serious due to environmental concerns, research and activities on renewable energy resources have rapidly gained importance. Therefore, solar energy is one of the most important alternatives as sustainable energy, both because of its inexhaustible source and because it is harmful to the environment. Photovoltaic cells are systems that convert photon energy from the sun into electrical energy. Efficient operation of photovoltaic cells depends on determining the panel angles. Optimizing the tilt angle of the PV modules and optimally orienting them to face the sun positively affects the amount of electrical energy to be produced from the systems. In this study, the working principle of photovoltaic cells according to panel angles and the factors related to energy efficiency as a result of these measurements will be examined meticulously. In line with the results obtained, it has been discussed that the effects of the sun's movement throughout the day and seasonal changes on energy production, and the dynamic change of panel angles increase the electrical energy production efficiency. In this context, it will also be investigated how more flexible and adaptive photovoltaic systems can be designed with the use of advanced technologies. In conclusion, this study will provide an in-depth understanding of how photovoltaic cells can operate more effectively depending on panel angles and will make a valuable contribution to research on the future increasing importance of solar energy use.

    Fatty acid transport receptor soluble CD36 and dietary fatty acid pattern in type 2 diabetic patients: a comparative study
    (Cambridge Univ Press, 2018) Ekici, Merve; Kisa, Ucler; Durmaz, Senay Arikan; Ugur, Elif; Nergiz-Unal, Reyhan
    Recently, it has been remarked that dietary fatty acids and fatty acid receptors might be involved in the aetiology of diabetes. Therefore, this study was conducted to determine the relationship between dietary fatty acid pattern, fatty food preferences and soluble CD36 (sCD36) and insulin resistance in type 2 diabetes mellitus (DM). The study was carried out with thirty-eight newly diagnosed type 2 DM patients and thirty-seven healthy volunteers, aged 30-65 years. In the study, socio-demographic characteristics, dietary fat type and fatty acid pattern of individuals were recorded. After anthropometric measurements were taken, blood CD36, glucose, TAG and insulin levels were analysed. The results showed that although the type of fatty acid intake did not differ between the groups (P>0.05), the consumption of olive oil in the type 2 DM group was lower than the control group (P<0.05). Mean blood glucose, insulin, insulin resistance, TAG and sCD36 levels were determined to be higher in the type 2 DM group (P<0.05). However, there was no correlation between sCD36 levels and homeostatic model assessment of insulin resistance (HOMA-IR) value, blood insulin and TAG levels, waist circumference, dietary fatty acid pattern and food preferences in the type 2 DM group (P>0.05). Crucially, elevated sCD36 levels increased the type 2 DM risk (OR 1.21, P<0.05). In conclusion, sCD36 level may be a possible biomarker, independent from the dietary fatty acid pattern, for type 2 DM owing to its higher levels in these patients. Therefore, the new insights make CD36 attractive as a therapeutic target for diabetes.

    Metabolik sendromlu bireyler günlük besin ögesi gereksinimlerini karşılayabiliyor mu?
    (2019) Kılınç, Fatma Nişancı; Çakır, Biriz; Ekici, Merve; Temizhan, Ahmet
    Amaç: Bu çalışma, metabolik sendromlu bireylerin beslenme alışkanlıkları, besin tüketimleri ve günlük besin ögesigereksinimlerinin karşılanma düzeyinin belirlenmesi amacıyla yapılmıştır.Gereç ve Yöntemler: Çalışma, 19 yaş üstü, Uluslararası Diyabet Federasyonu kriterlerine göre metabolik sendrom tanısıalmış 113 bireyde yürütülmüştür. Bireylerin boy uzunlukları, vücut ağırlıkları, bel çevreleri ölçülmüş, beden kütle indekslerihesaplanmış, demografik özellikleri, beslenme alışkanlıkları ile besin tüketim durumları sorgulanmış, elde edilen verilerönerilen değerler ile karşılaştırılmıştır.

    THE EFFECTS OF DAILY BREAKFAST CONSUMPTION ON GROWTH IN TURKISH STUDENTS
    (2021) Özkeçeci, Coşkun Fırat; Balamtekin, Necati; Ünay, Bülent; Ekici, Merve
    OBJECTIVE: Breakfast, defined as the most important meal of the day, contributed significantly to the daily nutrient intake and energy requirements. The importance of breakfast on growth is known. In this study, we aimed to determine whether primary and secondary school children receive adequate and balanced nutrition at breakfast, to assess the adequacy of their nutritional and energy values in their breakfast.MATERIAL AND METHODS: We prospectively reviewed the data of 105 students who were followed up between 31 January 2018 and 31 July 2018 in 3 different districts of Ankara. Children aged between 6-15 years were evaluated in the study. BEBIS (Beslenme Bilgi Sistemi) was used for food consumption, amount and content of the nutrients that students received at breakfast.RESULTS: A total of 105 students' (52 girls, 53 boys) a mean age of 11.5 (range, 6 - 15) years and with a mean Body Mass Index (BMI) of 19.17 (range 14.11 - 29.14) were determined. Average energy intake during the weekdays was 378.96 ± 131.64 kcal for weekdays, while average energy intake during the weekends was 625.68 ± 162.12 kcal. At the weekends, the amount of energy and nutrients intake of the students were found to be higher than on weekdays.CONCLUSIONS: We emphasized that breakfast is important to supply daily food and energy needs and it is important for physical growth.
