Gunduz, Selim; Korkmaz, Mustafa C.
This paper proposes a new probability distribution, which belongs a member of the exponential family, defined on (0,1) unit interval. The new unit model has been defined by relation of a random variable defined on unbounded interval with respect to standard logistic function. Some basic statistical properties of newly defined distribution are derived and studied. The different estimation methods and some inferences for the model parameters have been derived. We assess the performance of the estimators of these estimation methods based on the three different simulation scenarios. The analysis of three real data examples which one is related to the coronavirus data, show better fit of proposed distribution than many known distributions on the unit interval under some comparing criteria.

The continuity of the organizations is directly proportional to the satisfaction of the service recipients. The presence of many partners, beneficiaries and employees in cooperatives requires high cooperation. Therefore, it is important to reveal the service quality of the cooperatives and to determine the expectations of the partners. This study was carried out in Cukobirlik, which ranks third in Turkey cooperatives and first among the agricultural cooperatives in terms of number of partners, with the aim of determining the partners' service satisfaction, their perception related to cooperative activities and their intentions for diversification of these activities. 831 surveys were applied. 94.8% of the participants in the study are men and the agricultural production experience of 76.4% of them is over 21 years. It was seen that the satisfaction level of the partners from Cukobirlik's services is high in all dimensions, and the dimensions of assurance, competency and enthusiasm came to the fore compared to other dimensions. With the global pandemic of Covid-19, it has once again manifested itself that agricultural production is an activity that is the first and most affected by all extraordinary situations and affects all humanity with its results. The collective production model is a guarantee of sustainability.; Örgütlerin devamlılığı hizmet alanların memnuniyeti ile doğru orantılıdır. Kooperatiflerde çok sayıda ortak, yararlanıcı ve çalışanların varlığı iş birliğinin yüksek olmasını gerektirir. Bu nedenle kooperatiflerin hizmet kalitesinin ortaya konulması ve ortakların beklentilerinin belirlenmesi önemlidir. Bu çalışma, Türkiye’deki kooperatifler içerisinde ortak sayısı bakımından 3. sırada olan, tarımsal kooperatifler arasında da ilk sırada yer alan tarım satış kooperatiflerinde ortakların hizmetlerden memnuniyeti, kooperatif faaliyetleri ile ilgili algıları ve faaliyetlerin çeşitlenmesine yönelik niyetlerini belirlemek amacıyla Çukobirlik özelinde yapılmıştır. Çukobirlik’in faaliyetinin olduğu 11 ilde gönüllülük esasına göre 831 ortakla yüz yüze olarak anket uygulanmıştır. Çalışmaya katılanların %94.8’i erkek olup, %76.4’ünün tarımsal üretim deneyimi 21 yılın üzerindedir. Ortakların Çukobirlik’in hizmetlerinden memnuniyet düzeyleri her boyutta yüksek olduğu görülmüş olup, güvence ve yeterlilik boyutu ile heveslilik boyutu diğer boyutlara nazaran öne çıkmıştır. Tarımsal üretim faaliyetinin tüm olağanüstü durumlardan ilk ve en fazla etkilenen, sonuçları ile tüm insanlığı etkileyen bir faaliyet olduğu, küresel düzeyde yaşanan COVID-19 kaynaklı pandemi ile bir kez daha kendisini göstermiştir. Kolektif üretim modeli sürdürülebilirliğin bir güvencesidir.

Karaszewski, Robert; Modrzynski, Pawel; Muldur, Gozde Turkmen; Wojcik, Jacek
Environmental protection is currently one of the key priority areas of the European Union (EU). The search for precise tools to assess the impact of the economy, industry, or the production of individual products or services is crucial for an effective and efficient policy in environmental protection. Blockchain technology, originally related to the financial sector and cryptocurrencies, is an innovative solution that is increasingly being implemented by other areas of the economy and industry sectors. The authors reviewed the literature and based on it presented the possibilities and effects of using blockchain technology in Life Cycle Assessment (LCA), which is in line with the current development trends of this method. The analysis of the research conducted in this area also allowed to present not only the advantages of blockchain in LCA, but also the limitations of this technology and the potential directions of further research.

2021-12-01T00:00:00ZPandemic experiences of family physicians infected with the COVID-19: a qualitative studyEfeoglu, Ibrahim EfeKilincarslan, Omurhttp://openacccess.atu.edu.tr:8080/xmlui/handle/123456789/40332022-12-19T13:09:35Z2022-04-01T00:00:00ZPandemic experiences of family physicians infected with the COVID-19: a qualitative study
Efeoglu, Ibrahim Efe; Kilincarslan, Omur
Objectives Family physicians are usually patients' first point of contact with primary healthcare. This study aims to understand the experiences of family physicians who were infected with the COVID-19 and started working again. Study design and setting This qualitative study was conducted on 18 different family health centres in Adana. Data collection was performed through 18 interviews, each lasting an average of 46.6 min. The data were analysed using the qualitative content analysis method. Participants The study included 18 family physicians (9 women and 9 men), and there were no significant differences between them by gender or seniority. Results The results of the study have shown that family physicians who were infected with the COVID-19 and started working again have experienced high levels of anxiety at work. In addition, due to the fear of being reinfected, family physicians' social relations with their colleagues have decreased. The results are discussed under two themes: anxieties and social relationships. Conclusion In primary healthcare services, family physicians play a vital role during the pandemic. Many family physicians either lost their lives or got infected with the virus, recovered and worked in difficult conditions for a long time. Understanding the experiences of family physicians during the pandemic when they underwent COVID-19 and after they recovered could help to protect their psychological health and improve their work conditions.
