Öğe Türü: Öğe , The relationship among university students' recreational flow experience, psychological resilience, social connectedness, and life satisfaction(Frontiers Research Foundation, 2026) Güllü, Sevim; Şahinler, Yunus; Genç, Ayça; Bozyiğit, Elif; Biçer Baikoğlu, Selin; Genç, Neşe; Akkoç, OrkunIntroduction: This study aimed to examine the relationships among recreational flow experience, social connectedness, psychological resilience, and life satisfaction in university students. Methods: The sample consisted of 810 (416 female, 394 male) university students from various universities in Istanbul who voluntarily participated in the study. Data were collected using four standardized measurement instruments: the Recreational Flow Experience Scale, the Social Connectedness Scale, the Brief Resilience Scale, and the Satisfaction with Life Scale. Statistical analyses were conducted using SPSS and Hayes' PROCESS Macro (Model 4) to test both direct and indirect association among the variables. Results: Recreational flow significantly is positively associated with social connectedness and psychological resilience. Social connectedness and psychological resilience each is positively associated with life satisfaction. Furthermore, the relationship between recreational flow and life satisfaction was accounted for by a parallel mediation structure, in which social connectedness and psychological resilience operated as complementary pathways. Discussion: These results indicate that both social and psychological processes contribute to explaining how recreational flow relates to life satisfaction. The study highlights the distinct roles of social connectedness and psychological resilience in strengthening the positive outcomes of recreational flow and provides empirical evidence on the interconnections among these four constructs in the university student population.Öğe Türü: Öğe , The Imprints of Neonatal Death: A Qualitative Study on Neonatal Intensive Care Nurses' Experiences of Neonatal Death(W.B. Saunders Co, 2025) Kaya Meral, Deniz; Çalışkan, Belkıs Behice; Çekiç, Yasemin; Küçük Öztürk, Gülhan; Bağ, BeyhanBackground: Grief can pose significant challenges in nurses' lives, impacting both their personal well-being and work performance. Purpose: The aim was to examine neonatal intensive care nurses' (NICU) experiences with neonatal death. Methods: This study used a qualitative, phenomenological study design. The study group consisted of 17 nurses in the NICU. Data were collected online via Zoom using a semi-structured interview form and analyzed through a content analysis. The study was reported in line with the COREQ (Consolidated Criteria for Reporting Qualitative Research) checklist. Results: Two main themes and five sub-themes emerged. (1) "Grief" conveyed that nurses developed an empathetic bond with the newborn and family through their interactions during the care process, that confronting the empty incubator after the newborn's loss evoked profound and complex emotions, and that they sometimes had to maintain a delicate balance on ice to navigate their emotional intensity. (2) "Transformation" illustrated how grief was reflected in nurses' lives, influencing specific roles they assumed, and how they frequently experienced a deep need for contact following the loss of a baby. Implications for practice and research: To support the grieving process, structural interventions such as debriefings, reflective sessions, group-based psychosocial resilience workshops, and supervision should be promoted, along with flexible rest periods that allow nurses who need solitude to recuperate. Understanding the impact of newborn loss on nurses' lives may also guide the development of appropriate support interventions.Öğe Türü: Öğe , Stronger Minds, Better Lives: Exercise Self-Efficacy and Resilience as Serial Mediators in Oncology Nurses(MDPI AG, 2026) Oyur Çelik, Gülay; Turan, Mehmet Behzat; Balyan, Melih; Karaoğlu, Barış; Pepe, Osman; Dalbudak, İbrahim; Pepe, Bilgehan; Evyapan Aydın, Seda; Kara, Mustafa; Yiğit, SıhmehmetBackground: Oncology nurses are highly vulnerable to impaired mental health and reduced quality of life due to the emotionally demanding nature of their work. Although mental health is a well-established determinant of quality of life, the mechanisms underlying this relationship remain insufficiently understood. Objective: This study examined the effect of the mental health continuum on quality of life among oncology nurses and tested the serial mediating roles of exercise self-efficacy and psychological resilience. Methods: A cross-sectional design was conducted with 604 oncology nurses in Türkiye. Data were collected using the Mental Health Continuum—Short Form, the Exercise Self-Efficacy Scale, the Psychological Resilience Scale, and the WHOQOL-BREF. Serial mediation analysis was performed using PROCESS Model 6 with 5000 bootstrap resamples. Results: The mental health continuum had a significant positive effect on exercise self-efficacy (a1 = 0.08, p < 0.001) and psychological resilience (a2 = 0.05, p < 0.001). Exercise self-efficacy significantly predicted psychological resilience (d1 = 0.51, p < 0.001). Both exercise self-efficacy (b1 = 0.88, p < 0.001) and psychological resilience (b2 = 1.60, p < 0.001) were significant predictors of quality of life. The direct effect of the mental health continuum on quality of life remained significant (c′ = 0.65, p < 0.001), indicating partial mediation. Bootstrap results further confirmed that all indirect effects were statistically significant, as their 95% confidence intervals did not include zero. Conclusions: Quality of life is influenced not only by mental health but also by sequential cognitive and adaptive processes. Interventions targeting exercise self-efficacy and psychological resilience may enhance well-being among oncology nurses.Öğe Türü: Öğe , Predictors of Burnout in Parents of Children with Autism: The Importance of Physical Space(MDPI AG, 2026) Usta, Miraç Barış; Aker, Şeyma; Şenel, Melis Elif; Macit Efe, Meryem; Taflan, Feride Burcu; Bayrakdar, Uygar; Gülboy, Emrah; Kılınçel, Şenay; Kılınçel, OğuzhanParental burnout, characterized by emotional exhaustion and a sense of detachment, is a significant challenge for families of children with autism spectrum disorder (ASD). While traditional research often focuses on socioeconomic status, this study examines how physical living conditions and household characteristics influence burnout levels in the Turkish context. A relational survey model was conducted with 131 parents of children with ASD. Data were collected via online surveys using a Sociodemographic Data Form and the Maslach Burnout Inventory (MBI), which was adapted to the parenting role. Multiple linear regression analysis was applied to identify variables predicting total burnout scores. The analysis revealed that most sociodemographic variables, including income, education level, and parental age, did not significantly predict burnout. However, the "number of rooms in the house" was identified as the only statistically significant predictor (p = 0.033). Specifically, as the number of rooms increased, the total burnout scores of parents significantly decreased. The findings suggest that physical living space serves as a critical "spatial resource" and a protective factor against parental burnout. For families of children with ASD, having a private area for self-regulation is more decisive for mental health than economic status alone. Future support strategies should prioritize improving the quality of life through spatial arrangements and respite services.Öğe Türü: Öğe , In‑vitro investigation of bone temperature changes in osteotomies performed with different brands of implant burs(Springer, 2025) Şarkbay, Ömer Faruk; Mihmanlı, Ahmet; Cora, HakanThe aim of this study was to investigate in-vitro the temperature changes occurring in the bone during drilling with implant drills manufactured by different companies. Bone blocks obtained from fresh bovine ribs were used in the study. Bone blocks were drilled with drills manufactured by Ankylos, Astra Tech, Nobel Biocare, Bredent and Straumann implant brands at an ambient temperature of 30 ± 2° C under a constant pressure of 2 kg. Two K-type thermocouple sensors were placed on the bone blocks at 5th and 10th mm depths and the temperature changes were measured at a distance of 1 mm from the implant drill. In the study, working models were created under different conditions for implant socket preparation. In group 1, the first time drills were used at 150 rpm without irrigation, in group 2, the first time drills were used at 1200 rpm with 40 ml/min irrigation, in group 3, the 30th time drills were used at 150 rpm without irrigation, and in group 4, the 30th time drills were used at 1200 rpm with 40 ml/min irrigation. All osteotomy procedures were performed with 3.5 ± 0.3 mm diameter burs for a period of 8 s and the temperature values obtained at equal time intervals were recorded. Repeated Measures and Kruskall Wallis-H tests were used for statistical analysis of the data. No significant difference was observed between the implant drills and the temperature changes in the bone during drilling (p < 0.05). None of the groups reached critical temperature values (47° C+) throughout the study. At the 5th and 10th mm depths, the temperature changes in the sensors used were close to each other. It was also calculated that although the average temperatures were close to each other in the non-irrigated and irrigated systems, the difference values obtained by subtracting the initial temperature were significantly higher in the non-irrigated systems. The results showed that implant drills did not cause significant temperature increases in bone blocks depending on the difference in manufacturers (Ankylos, Astra Tech, Nobel Biocare, Bredent, Straumann) and the number of uses. It was also concluded that irrigated and non-irrigated systems are safe as long as they are used under the recommended conditions.
