BACKGROUND: Social isolation required by the pandemic has led to some changes in individuals’ eating and lifestyle habits. OBJECTIVE: This study aimed to examine the change in nutrition and lifestyle habits of Turkish people during the COVID-19 outbreak and investigate the effects of individuals’ attitudes to healthy eating on this change. METHOD: At the beginning of the pandemic, individuals over the age of 18 participated in this cross-sectional study using an online questionnaire. Demographic information (age, gender, education level, place of residence and occupation), anthropometric data (reported weight and height); nutritional behavior information (number of meals per day, changes in consumption of various foods, use of nutritional supplements, etc.) and changes in lifestyle habits were requested from the participations. In addition, the Healthy Nutrition Attitude Scale (ASHN) was used to determine the healthy eating attitudes of the participants. RESULTS: A total of 432 volunteers participated in the study. It was revealed that body weight increased in 38.0%of the participants and activity level decreased in 73.1%of them during the initial stage of the pandemic. Nevertheless, 44.7%of participants reported increased sleep time, 77.8%reported increased social media use, and 66.7%reported increased stress and anxiety. It was found that the most commonly used nutritional supplements during this period were vitamin C, vitamin D and multivitamin complex. Women have significantly higher ASHN scores compared to men (p <  0.001). The total ASHN scores of those whose body weight did not change and those who increased their activity level were found to be significantly higher. It was determined that as the age and education level increased, the healthy eating attitude increased. CONCLUSION: In this study, findings regarding the negative effects of the Covid 19 quarantine on the nutrition and lifestyle of the Turkish people are presented. However, those with a positive attitude toward healthy eating were observed to have better weight control and eating habits and stress management during the pandemic. Therefore, it is thought that the dissemination of healthy eating attitudes in society may contribute to the maintenance of physical and mental health in the event of a pandemic.

The aim of this study is to group OECD countries using the better life index indicators through multidimensional scaling analysis. The Better Life Index consists of thirty-three variables under the dimensions of material living conditions (income and wealth, work and earnings, housing conditions) and quality of life (health status, work-life balance, education and skills, social connections, civic engagement and governance, environmental quality, personal safety and life satisfaction). These thirty-three indicators constitute the variables of the multidimensional scaling analysis. As a result of the analysis, the positions of countries in two-dimensional space were obtained and it was observed that some countries formed distinct clusters. In this way, OECD countries are compared not on the basis of a selected indicator, but on the basis of an approach that encompasses all the indicators of the Better Life Index.

In this study, Travelling Salesman Problem (TSP), an NP-hard problem, is addressed. In order to get the best results with a view to directing TSP heuristics, the ant colony algorithm was used for solution purposes. The purpose was to solve the problem of setting a course for the bread distribution trucks of Istanbul Halk Ekmek (Public Bread) Company using the ant colony algorithm on TSP. A liquid called Pheromone, which ants release in order to establish communication among them, is known as the most fundamental matter to provide this communication. In this research, artificial ants, which function with the logic of finding the shortest path in the area where they are located, were utilized. The purpose of our programme is to determine the shortest route for the arrival of the distribution trucks to the kiosks where bread is sold to the public. The route developed by the programme is displayed over Google maps. Motivation/Background: Explain the importance of the problem investigated in the paper. Include here a statement of the main research question. Method: Give a short account of the most important methods used in your investigation. Results: Present the main results reported in the paper. Conclusions: Briefly present the conclusions and importance of the results. Concisely summarize the study’s implications. Please do not include any citations in the abstract.

Bir örgütün nelere sahip olduğunu, neleri iyi yapabildiğini belirleyebilmesi için etkili ve uygun stratejileri ortaya koyabilmesi gerekir. Proaktif bir metedoloji ile çalışmalara temel dayanak olarak oluşturulacak işlevsel analiz, sağlık kuruluşlarını izleme, analiz ve değerlendirme ile iyileştirme çalışmalarına zemin hazırlar. İşlevsel analiz ile yapılan değerlendirmeler; sağlık kuruluşlarında sunulan hizmetlerinin hem verimliliği hem de etkinliğinin değerlendirilmesini sağlar. Sağlık kuruluşlarının gelişme fırsatlarının belirlenmesi ve faaliyetlerin periyodik olarak takip edilmesi, yöneticilerin farkındalık ve bilgi düzeylerini yükseltir. Örnek uygulamaları ortaya çıkartarak diğer sağlık kuruluşlarınca da kullanabilme imkanı oluşturur. Kuruluşun işlevsel analiz aşamaları ve oluşturulacak alt göstergeler, yöneticilere karar vermede kolaylık ve objektiflik sağlar. Kapsamlı bir çalışma ile işlevsel analiz için oluşturulacak parametreler, tüm sağlık kuruluşlarına uygulanabilir şekilde ve bunlara ek ihtiyaçlar, özel durumlar için revize edilebilir veya geliştirilebilir göstergelerle yaygın hale getirilebilir. Analiz sonucunda elde edilen veriler belirlenen işlevsel analiz unsurları ile karşılaştırmalı olarak değerlendirilerek, farklı ölçütlerde gruplandırılmış ve etkin bir sisteme yönelik ipuçları ortaya koyar.
