The Diophantine equation revisited
No full textLet k,l >= 2 be fixed integers, and C be an effectively computable constant depending only on k and l. In this paper, we prove that all solutions of the equation (x + 1)(k) + (x + 2)(k) + ... + (lx)(k) = y(n) in integers x, y,n with x, y >= 1, n >= 2, k not equal 3 and l 1 (mod 2) satisfy max{x, y, n} < C. The case when is even has already been completed by the second author (see [24])
The Changing Role of University Faculty in the Era of Artificial Intelligence: A Systematic Literature Review
No full textThe integration of Artificial Intelligence (AI) in higher education has profoundly influenced teaching and learning processes. This study investigates the evolving roles of university faculty in the AI era by synthesizing findings from peer-reviewed literature, policy reports, and institutional research. A systematic literature review was conducted based on 32 key sources published between 2018 and 2024. The results reveal three significant transformations: (1) pedagogical innovations with AI-assisted tools, (2) the shift in administrative responsibilities and decision-making supported by AI analytics, and (3) emerging ethical roles and the need for AI literacy among faculty. The study concludes that AI enhances efficiency and demands a reconfiguration of professional identity, calling for continuous professional development, ethical frameworks, and institutional support
Artificial Intelligence and Organizational Culture: Navigating Contextual Shifts in Structure, Ethics, and Behavior
No full textThis article explores the transformative impact of Artificial Intelligence (AI) on organizational culture. With the increasing integration of AI technologies into business operations, organizational dynamics, decision-making structures, and cultural norms are experiencing significant shifts. This qualitative-descriptive study reviews the literature and synthesizes empirical and theoretical perspectives on how AI reshapes organizational culture, focusing on decentralization, transparency, digitalization, and employee-manager relations. The article also highlights the role of deep learning and artificial neural networks as key technological drivers of this cultural evolution. The results underline the need for adaptive organizational models that integrate AI ethically and strategically
Kuaförlerin İş Yaşam Kalitesi Üzerine Bir Araştırma
No full textKuaförler, gün boyu insanlarla sürekli iletişim halinde olan, yoğun çalışma yaşamına sahip bir meslek grubudur. Bu grupta çalışan kişilerin mesai saatlerinin fazla, dinlenme sürelerinin az oluşu bunun dışında stresli ve yorucu bir iş yaşamı sürmeleri iş yaşam kalite durumlarını araştırmaya sebep olmuştur. Bu çalışmanın amacı, kuaförde çalışan iş görenlerin iş-yaşam kalitesini belirlemek ve demografik özelliklere göre farklılıklar olup olmadığını belirlemektir. Bu amaç doğrultusunda, Bartın ilinde çalışan, araştırmaya katılmayı kabul eden 80 kuaför çalışan katılımıyla araştırma gerçekleştirilmiştir. Çalışmanın yöntemi kolayda örneklem olarak belirlenmiştir. Hazırlanmış olan anket formu Google Forms aracılığıyla çalışanlara gönderilerek veriler toplanmıştır. Çalışmada kuaför iş görenlerin iş yaşam kalitelerini belirlemek amacıyla Çiçek’in (2005) geliştirdiği; geçerlik ve güvenirliğini Aba’nın (2009) yaptığı “İş Yaşam Kalitesi Ölçeği” uygulanmıştır. Ölçek, üç boyuttan meydana gelmektedir. Bunlar; iş ortamı, çalışma koşulları ve sağlanan hizmetler boyutları olup, ölçekte 15 ifade yer almaktadır. Çalışmada ulaşılan verilerin analizleri SPSS paket programı ile yapılmıştır. Çalışmada ulaşılan veriler, tanımlayıcı istatistiksel yöntemler kullanılarak değerlendirilmiştir. Kurulan modeller doğrultusunda regresyon analizleri ve manova analizi yapılmıştır. Çalışmanın bulgularına göre elde edilen sonuca bakıldığında, demografik özelliklerin iş yaşam kalitesi ölçeğini etkilediği söylenebilir. Yapılan manova analizi sonucunda katılımcıların yaşlarına göre çalışma koşulları boyutu ve sağlanan hizmetler boyutu puanları arasındaki farkın anlamlı olduğu saptanmıştır
The validity and reliability of the Turkish version of the 6-item female sexual function index (FSFI-6) and the relationship between climacturia and female sexual dysfunction
No full text© 2021, The Author(s), under exclusive licence to Springer Nature Limited.This study aims to assess the validity and reliability of the Turkish version of the FSFI-6 questionnaire,an abbreviated version of FSFI-19,a common tool for evaluating female sexual function. The study included 120 female patients aged between 18–65 years who presented to the urology clinic between December 2019 and March 2020. The Turkish version of FSFI-6 was translated from the English version for validation. The abridged FSFI-6 questionnaire consists of questions 2, 4, 7, 11, 16, and 17 of the FSFI-19 form. We recorded the demographic data of the patients. All subjects filled out the FSFI-19 and FSFI-6 questionnaires. The patients were asked to fill out the questionnaires again after two weeks. The mean age of the subjects was 46.58 ± 9.89 years (28–63). The results of the reliability analysis indicated that the intraclass correlation coefficient of the total FSFI-6 score was 0.92 (weighted kappa coefficients of individual items, 0.868–0.975) and the Cronbach’s alpha was 0.862. The validity analysis indicated that the mean total FSFI-6 score was strongly correlated with the mean FSFI-19 score (p < 0.001, r = 0.997). In the test-retest analysis,the kappa coefficient was calculated as 0.891. The FSFI-19 and FSFI-6 scores of the patients with (n = 52) and without climacturia (n = 68) were compared, and it was observed that the scores of the patients with climacturia were significantly lower than those without climacturia (p < 0.001). The abbreviated FSFI-6 questionnaire is a valuable tool for screening women with FSD. It can be used more extensively due to being short and easy to apply. Our results approve the Turkish version of the questionnaire as a valid and reliable tool for evaluating FSD
EVALUATION OF PREMATURELY AGING EMPLOYEES WITHIN THE SCOPE OF OLD AGE INSURANCE
No full textThe long-term insurance branch that covers the income losses incurred by employees in the event of old age, which they inevitably face as a social risk, is old age insurance. In general, the conditions for entitlement to a pension in case of old age arise in different ways due to the personal situation of the insured or due to the work in which he works. “Retirement in case of premature aging” provides the insured with the opportunity to retire more easily in the presence of certain special circumstances. In general, the requirement to be eligible for early aging, which is less well-known and less common in practice than the conditions for earning an old-age pension, is regulated by the 28th article of the Law number 5510 as follows: “Insured persons who have reached the age of 55 and have been found to have aged prematurely will benefit from the old-age pension if they meet other conditions other than age”.Although the age requirement required to qualify for a pension has not been filled in terms of time, people who biologically age like a person who has reached the age required to qualify for an old- age pension and whose working capacity has decreased to this level are considered prematurely aged individuals.In our study, it is aimed to evaluate this special type of pension, which is generally not well known except for those who are entitled to a normal old-age pension. By examining the legal regulations and conditions of entitlement to early retirement, it will be emphasized why this special retirement condition, which is usually not found much in judicial decisions, is less common in practice and its necessity in legislation
Laser micro-polishing of stainless steel for antibacterial surface applications
No full textIn this work laser micro polishing (LMP) of cold rolled 0.3 mm thick 304 stainless steel with a pulsed fibre laser is studied, for applications
where antibacterial properties are required. Due to its production method, the initial surface roughness of the tested material was considerably
low (Sa=85.3±2.8 μm), rendering a demanding case for the laser polishing process. Accordingly, process feasibility under three different
atmospheric conditions, namely ambient, Ar and N2 atmosphere, was investigated. A large set of process parameter combinations was tested
and initial analysis was carried out to identify the polishing feasibility by inspection under an optical microscope. Once the feasibility window
was determined, a primary characterization was made on selected surfaces for roughness and waviness. Results show that in some process
conditions belonging to the explored feasibility range, surface roughness could be decreased by 50%
