Examining the determinants of intention to use cryptocurrency in the framework of the utaut model

Bu çalışmada, blokzincir teknolojisine dayanan kripto paraların kullanım niyetini etkileyen faktörlerin, Teknolojinin Kabul ve Kullanımı Birleştirilmiş Teorisi çerçevesinde incelenmesi amaçlanmaktadır. Çalışma verileri anket aracılığı ile toplanmıştır. Bandırma ilçesinde görev yapan bankacılar çalışmanın ana kütlesini oluşturmaktadır. Evren büyüklüğü 230 kişi, örneklem büyüklüğü 145 kişidir. Veri analizinde SPSS Versiyon-21 yazılımı kullanılmıştır. Çoklu korelasyon analizi, kripto para kullanma niyetiyle negatif ve anlamsız ilişkiye sahip faktörü algılanan risk şeklinde, pozitif ve anlamlı ilişkiye sahip faktörleri ise performans beklentisi, çaba beklentisi, sosyal etki ve kolaylaştırıcı koşullar şeklinde tespit etmiştir. Performans beklentisi ve çaba beklentisi faktörlerinin, kripto para kullanma niyetini pozitif ve anlamlı biçimde etkilediği yapılan çoklu regresyon analizi sonucunda tespit edilmiştir.The purpose of this study is to analyze the factors affecting the intention to use cryptocurrencies based on blockchain technology, within the framework of the Unified Theory of Technology Acceptance and Use. The study data were collected through a questionnaire. Bankers working in Bandırma constitute the main body of the study. The population size is 230 people and the sample size is 145 people. SPSS Version-21 software was used for data analysis. The multiple correlation analysis showed that the factor with a negative and insignificant relationship with the intention to use cryptocurrency was perceived risk, and the factors with a positive and significant relationship were performance expectancy, effort expectancy, social influence, and facilitating conditions. As a result of the multiple regression analysis, it was determined that the performance expectancy and effort expectancy factors positively and significantly affect the intention to use cryptocurrencies

Novel Inflammatory Prognostic Markers in Lung Cancer Patients Treated with Definitive Chemoradiotherapy

Primary lung cancer is the most common cancer worldwide and is an increasingly common problem. The primary endpoint of this study was; to investigate the effect of radiotherapy dose and neutrophil-lymphocyte ratio (NLR) on overall survival (OS) and progression-free survival (PFS). We retrospectively examined 99 patients who were stage III A and stage III B at the time of diagnosis, who did not receive surgical treatment, and who received definitive chemoradiotherapy. Data of patients such as sex, age, ECOG status, tumor location, pathological subtype, radiotherapy dose, type of chemotherapy, neutrophil/lymphocyte ratio (NLR), and some biochemical parameters and PFS and OS were included in the study by scanning the patient's files. The radiotherapy cut-off value was accepted as 60 Gray. OS was statistically better in patients who received radiotherapy at doses of 60 Gray and above. When the patients with radiotherapy dose less than 60 Gy and patients with more than 60 Gray were evaluated in two groups, the overall survival was 8,569 ± 1,404 / month and 14,326 ± 1,209 / month, respectively. (p <0.05). When we evaluate the patients based on NLR; It was observed that the overall survival of patients below NLR 4 at the time of diagnosis was statistically significantly better. The overall survival of patients with NLR <4.0 and NLR> 4 was 14.32 ± 1.30 / month and 10.54 ± 1.16 / month, respectively. (p <0.05
