Öğe Examining the Relationship Between Social Media Addiction, Fear of Missing Out, Loneliness, and Life Satisfaction Among Youth: A Cross-Sectional Study(Serbian Psychologists, 2026) Işık, Nurten Arslan; Keleş, Dilsa Azizoğlu; Sandıkçı, İrem Nur; Kotyk, Taras; Okanlı, AyşeThis cross-sectional study examines the relationships among social media addiction, fear of missing out (FoMO), loneliness, and life satisfaction among young adults. Data were collected from 700 participants aged 18-29 years via an online survey administered between May and June 2024. Validated scales were used to assess key variables: the Bergen Social Media Addiction Scale, the Fear of Missing Out Scale, the UCLA Loneliness Scale, and the Satisfaction with Life Scale. Structural Equation Modeling revealed that life satisfaction was positively associated with loneliness. Social media addiction was strongly associated with FoMO, while FoMO had an indirect negative effect on life satisfaction through social media addiction. These findings shed light on the underlying mechanisms between social media addiction, FoMO, loneliness, and life satisfaction. Such insights can provide significant implications for developing interventions (e.g., digital well-being programs) to help young adults manage their social media use more effectively. Promoting mindful and balanced social media engagement may contribute to enhancing life satisfaction and overall mental well-being.Öğe A Comparative SWOT Analysis of Hospital Management Protocols for Radiation Accidents in Türkiye and Japan(2025) Kolçak, DilekBackground: The situation in which radiation emerges uncontrollably is referred to as a radiation accident. Radiation accidents constitute emergencies that can have severe impacts on public health. Therefore, it is of critical importance for hospitals providing healthcare services to be adequately prepared for such incidents. Materials and Methods: This study aims to compare the hospital management protocols for radiation accidents in T & uuml;rkiye and Japan using the strengths, weaknesses, opportunities, threats (SWOT) analysis method. As a country that has experienced a radiation accident, Japan's postincident developments are compared with T & uuml;rkiye's current situation. The study first examines the radiation safety regulations, healthcare policies, and hospital management strategies of both countries. While T & uuml;rkiye has established general protocols under the Hospital Disaster and Emergency Plan (HAP) and for Chemical, Biological, Radiological, and Nuclear (CBRN) incidents, Japan has enhanced its crisis management and emergency response systems following the 2011 Fukushima Nuclear Accident. Within the framework of the SWOT analysis, the strengths and weaknesses of both countries, potential threats, and opportunities for improvement are analyzed in detail. Results and Discussion: This study highlights how T & uuml;rkiye can benefit from Japan's crisis management experience to enhance its preparedness for radiation accidents. The analysis reveals that T & uuml;rkiye has significant shortcomings, particularly in training, drills, and hospital infrastructure. However, its investments in nuclear energy provide opportunities for development through international collaborations. On the other hand, although Japan possesses advanced radiation monitoring systems and extensive experience, it remains under constant threat due to its high concentration of nuclear power plants and exposure to natural disasters. Conclusion: To prevent radiation accidents, it is recommended to develop a hospital management model based on international standards. Additionally, effective intervention strategies should be formulated through the collaborative decision-making of hospital administrators, healthcare professionals, and policymakers to ensure a comprehensive response to radiation accidents.Öğe Linking Extended Business Responsibility to Sustainable Environmental Awareness: Evidence on the Mediating Role of Environmental Values(Wiley, 2025) Avunduk, Zehra Binnur; Kahveci, Eyüp; Habip, ElifEco-conscious businesses are increasingly adopting sustainable materials and improving production efficiency to reduce carbon emissions. These efforts not only minimize waste but also help conserve natural resources. Through extended business responsibility (EBR), firms actively promote sustainable consumption by raising consumer awareness. As awareness grows, purchasing behavior shifts toward environmentally responsible choices, ultimately reducing ecological harm. In contexts where environmental values (EVs) are prominent, social pressure often drives firms toward more sustainable practices. This study addresses a gap in the literature by examining the mediating role of EVs in the relationship between EBR and sustainable environmental awareness (SEA). Based on survey data from 396 participants in Türkiye, partial least squares structural equation modeling (PLS-SEM) was employed for analysis. The findings reveal that EVs partially mediate the relationship between EBR and SEA, serving as a catalyst that enhances the effect of EBR on sustainability awareness. The results provide valuable insights for a wide range of businesses, including manufacturers and e-commerce firms. By aligning with the expectations of environmentally conscious consumers, companies can not only strengthen their sustainability agendas but also gain a sustainable competitive advantage. This study contributes to the literature on sustainable business practices by applying PLS-SEM in the context of an emerging economy and highlighting the critical role of EVs in fostering sustainability awareness.Öğe Alzformer: Video-Based Space-Time Attention Model For Early Diagnosis Of Alzheimer’s Disease(Pergamon-Elsevier Science, 2025) Akan, Taymaz; Akan, Sara; Alp, Sait; Ledbetter, Christina Raye; Bhuiyan, Mohammad Alfrad NobelEarly and accurate Alzheimer’s disease (AD) diagnosis is critical for effective intervention, but it is still challenging due to neurodegeneration’s slow and complex progression. Recent studies in brain imaging analysis have highlighted the crucial roles of deep learning techniques in computer-assisted interventions for diagnosing brain diseases. In this study, we propose AlzFormer, a novel deep learning framework based on a space–time attention mechanism, for multiclass classification of AD, MCI, and CN individuals using structural MRI scans. Unlike conventional deep learning models, we used spatiotemporal self-attention to model inter-slice continuity by treating T1-weighted MRI volumes as sequential inputs, where slices correspond to video frames. Our model was fine-tuned and evaluated using 1.5 T MRI scans from the ADNI dataset. To ensure the anatomical consistency of all the MRI data, All MRI volumes were pre-processed with skull stripping and spatial normalization to MNI space. AlzFormer achieved an overall accuracy of 94 % on the test set, with balanced class-wise F1-scores (AD: 0.94, MCI: 0.99, CN: 0.98) and a macro-average AUC of 0.98. We also utilized attention map analysis to identify clinically significant patterns, particularly emphasizing subcortical structures and medial temporal regions implicated in AD. These findings demonstrate the potential of transformer-based architectures for robust and interpretable classification of brain disorders using structural MRI.Öğe The Mediating Role of Psychological Empowerment and Trust in Leader on the Effect of Inclusive Leadership on Innovative Work Behavior: A Field Study in the Textile Industry in Turkiye(Sage Publishing, 2025) Amirli, Hamran; Fettahlioğlu, Ömer Okan; Gül, Necmettin; Tatli, Hasan SadikThe research is conducted with employees in the textile sector operating in Kahramanmarasx/T€urkiye. The study aims to examine the effect of inclusive leadership on employees’ innovative work behavior, as well as the mediating roles of trust in leader and psychological empowerment in this interaction. This cross-sectional study collected data from 275 employees in the textile industry of Kahramanmarasx/T€urkiye. The data were analyzed by the structural equation modeling (SEM) method using SmartPLS 4 software. The results of the analysis revealed that inclusive leadership has a direct positive effect on IWB. In addition, it was determined that inclusive leadership increases psychological empowerment and trust in leader. While psychological empowerment was found to have a significant mediating role in the relationship between inclusive leadership and innovative work behavior, the mediating role of trust in leader was not supported. The findings suggest that focusing on psychological empowerment in inclusive leadership practices is effective in increasing IWB. The limited effect of trust in leader on innovative work behavior indicates the complexity of leadership and employee interactions. Theoretical and practical implications and recommendations are presented at the end of the study.Öğe Corporate Social Responsibility Campaigns for Behavior Change and the Greenwashing Trend(Nova Science Publishers, 2025) Cicerali, Eyyüb EnsariCorporate social responsibility (CSR) concerns the ethical duties in service of society and the environment. Advocating and realizing effective practices for social and natural welfare is its mission. On that note, awakening the society concerning environmental hazards, developing self-transcendental values in people, and addressing sustainability problems such as global warming, deforestation, or resource depletion are its central targets. Organizations can effectively use CSR as a behavior management tool to foster and promote green practices among individuals. Nevertheless, it would be wise to be careful of greenwashing. Greenwashing is the deliberately misleading portrayal of a company or product as more environmentally friendly than it actually is. Tags such as "green," "sustainable," or "organic" are equated with being upscale and pricey; therefore, they can be used as marketing ploys. Thus, to decipher and prevent greenwashing, normative practices such as the development of laws/regulations, the standardization of CSR reports, and the implementation of certification and ecolabeling are currently observable. What is additionally suggested here is to provide public mass education on biospheric values, cognitive dissonance and planned behavior change mechanisms, as well. Since consumers are also responsible parties in cases of greenwashing, they need to be knowledgeable and analytical when evaluating organizations' claims of environmental responsibility. Environmentally responsible people would breed like-minded organizations. © 2025 Nova Science Publishers, Inc.

In this study, 4972 people with different demographic characteristics participated in this research and data were collected with a questionnaire method consisting of a 5-point Likert scale. The data obtained were in order to understand the effects of demographic variables on medication use and quality of life. Within the framework of the study, the relationship between demographic factors such as age, gender, educational status, marital status and medication use, medication recommendation and the number of medications used analysed in detail. After statistical analyses using ANOVA and Chi-square analyses, it found that medication use differed especially according to age and marital status, while medication recommendation was significantly related to gender, educational status and marital status. In terms of other findings, in addition to demographic factors, regular physical activity and sports positive effects on medication use. It was also determined that the number of medication used was significantly related to loneliness and feeling of helplessness. It also found that the feeling of loneliness and medication use pattern were in a significant relationship in individuals engaged in sports and physical activity. In addition, it was found that there was a significant relationship between medication intake and quality of life in individuals engaged in sports and physical activity. After this study, it has been revealed that it is a very important source to understand the relationship between medication use and quality of life in elderly individuals who do sports and physical activity and the importance of encouraging elderly individuals to do more physical activity. © 2025, Campus EDUCA SPORTIS S.L..

This study is part of a doctoral research which focuses on uncovering the acoustic identity and soundscape of Derinkuyu Underground City, a unique subterranean heritage site in Cappadocia, Turkey. Adapting the framework of ISO/TS 12913-2:2018, the research integrates soundscape methodologies with virtual reality (VR) to reconstruct the auditory experience of the site. Virtual soundwalk as an innovative method is significant in defining soundscapes and uncovering their historical narratives. This particular study aims to adapt and refine the virtual soundwalk methodology outlined in ISO/TS 12913-2:2018 to describe the soundscape of Derinkuyu Underground City, an urban-scale interior environment. Key interior typologies were identified based on function, scale, and spatial hierarchy, forming a structured VR soundwalk that guides participants through different levels of the city, from the entrance to the deepest, seventh level. The chosen typologies represent the entirety of the city's levels and spaces. The models integrate distinctive sound sources specific to each interior space, establishing a taxonomy and enriching these environments with sound scenarios. The scenarios were auralized using ODEON software and integrated into the virtual reality models. Auralized sound scenarios, developed using ODEON software, were embedded into 3D VR models to simulate the acoustic conditions of the underground spaces. At designated listening points, participants experience immersive reconstructions of historical soundscapes, reflecting the functional and social dynamics of the site. This study underscores the significance of soundscape in interpreting cultural heritage and highlights the potential of VR technology in preserving and experiencing historical acoustic environments. By refining virtual soundwalk methodologies, it contributes to advancing soundscape research and its applications in heritage conservation. © Copyright 2012 - 2025 IIAV - All Rights Reserved.Öğe The Mediating Role of Climate Change Mitigation Behaviors in the Effect of Environmental Values on Green Purchasing Behavior within the Framework of Sustainable Development(Walter de Gruyter GmbH, 2025) Yilmaz, GoncaGlobal environmental challenges, including the depletion of natural resources, pollution, and population growth, have significantly impacted modern lifestyles. The environmental and socioeconomic dimensions of this reality are represented by climate change, one of the major threats facing the planet. People's environmental values and the green behaviors they exhibit based on these values are crucial in mitigating significant environmental problems, such as climate change. In this context, raising environmental awareness and motivating individuals to contribute to sustainable development and the circular economy particularly environmental protection can serve as an effective starting point. In line with this idea, data were collected from 236 participants in Istanbul in 2024 using the convenience sampling method. The data collected through the survey technique in the study were analyzed using the SPSS program and PROCESS, a macro developed for SPSS. In addition, confirmatory factor analysis and path analysis were performed with the Python programming language, and fit index was also presented. The research findings reveal a significant relationship between environmental values and green purchasing behavior. The mediating role of climate change mitigation behavior was also found.Öğe Deep Learning in neuroimaging for neurodegenerative diseases: State-of-the art, Challenges, and Opportunities(Elsevier B.V., 2025) Akan, Taymaz; Alp, Sait; Ledbetter, Christina Raye; Tafti, Ahmad P.; Arevalo, Octavio; Bhuiyan, Mohammad Alfrad NobelNeuroimaging is commonly used to diagnose neurodegenerative diseases (NDDs), providing crucial insights into brain changes before clinical symptoms manifest. Deep learning (DL) for neuroimaging can improve early diagnosis and disease monitoring. Clinical implementation of DL faces challenges in accurately representing realworld data. Recent models, particularly those focused on diagnostic categorization, have achieved high accuracy, but their applicability to patients is limited. Conflicting inferences have been reported, with findings from small cohorts generalizing conclusions without considering inter-scanner, intra- and inter-site variations. A theoretically feasible method involves gathering a comprehensive dataset that encompasses all patient demographics, but this presents practical challenges including harmonization, data incompleteness, class imbalance, and substantial costs. Existing research has also mostly focused on common NDDs like Alzheimer's Disease (AD) and Parkinson's Disease (PD). This contribution expands the literature by looking at a wider range of NDDs, exploring the latest advancements in applying deep learning algorithms to neuroimaging analysis for the diagnosis and monitoring of NDDs, including AD, Frontotemporal Dementia (FTD), Lewy Body Dementia, PD, Huntington's Disease, Amyotrophic Lateral Sclerosis, and Multiple Sclerosis. We emphasize how these approaches are handling spatial/temporal information available in brain volume imaging data. We conclude by discussing the challenges associated with the use of voxel-based, patch-based, ROI-based, and slice-based approaches in brain volume imaging. These challenges are further compounded by issues such as inter-site and inter-scanner variability, class imbalances in medical datasets, and the scarcity of accurately annotated data, all of which impact the performance and generalizability of deep learning models.Öğe Adapting the metaverse perception scale for Iranian nursing students: translation and psychometric assessment(Springer, 2025) Aghabarary, Maryam; Yıldırım, Tuğba Öztürk; Norouzinia, RoohangizThe integration of metaverse technologies into healthcare education is expand ing globally. However, there is a lack of culturally validated instruments to assess students’ perceptions within the Iranian context. This study aimed to evaluate the psychometric properties of the Persian version of the Metaverse Perception Scale among Iranian nursing students. A cross-sectional psychometric study was con ducted with 436 nursing students. The translated scale underwent Exploratory Fac tor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Internal consistency was assessed using Cronbach’s alpha. Convergent and discriminant validity were evaluated through Composite Reliability (CR), Average Variance Extracted (AVE), inter-construct correlations, √AVE, MSV and ASV. Factor analysis revealed a four factor structure—Education, Technology, Lifestyle, and Challenges—which ex plained 67.08% of the total variance. CFA results indicated that the refined 20-item version of the questionnaire had a good overall model fit (χ²/df=1.647; CFI=0.958; RMSEA=0.054). All CR values and AVE values were above 0.70 and 0.50, re spectively, supporting convergent validity. For all factors, √AVE values exceeded inter-construct correlations, and both MSV and ASV were lower than AVE, sup porting discriminant validity. The scale demonstrated strong internal consistency (Cronbach’s alpha=0.917−0.822). The Persian version of the Metaverse Perception Scale (P-MPS) is a valid and reliable scale for assessing nursing students’ percep tions of metaverse technologies in educational settings. This scale shows strong potential for application in both researcÖğe Smart Contracts, Blockchain, and Health Policies: Past, Present, and Future(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Kurt, Kenan Kaan; Timurtaş, Meral; Ozaydin, Fatih; Türkeli, SerkanThe integration of blockchain technology into healthcare systems has emerged as a technical solution for enhancing data security, protecting privacy, and improving interoperability.

This review includes 80 core studies published between 2019 and 2025, identified through searches in PubMed, Scopus, and Web of Science using the PRISMA method. Risk of bias and methodological quality were assessed using the Joanna Briggs Institute tool. The findings highlight the potential of blockchain-enabled smart contracts in health policy management, emphasizing their advantages, limitations, and implementation challenges. Additionally, the research underscores their transformative impact on digital health policies in ensuring data integrity, enhancing patient autonomy, and fostering a more resilient healthcare ecosystem. Recent advancements in quantum technologies are also considered as they present both novel opportunities and emerging threats to the future security and design of healthcare blockchain systems.Öğe Comparison of University Students' Awareness of Radiation Protection before and after Hospital Internship(The Korean Association for Radiation Protection, 2025) Colak, GülcihanThis study aims to compare the pre-and post-application results of university students' knowledge regarding radiation protection. Materials and Methods: The study was conducted on 116 students enrolled in the medical imaging and radiotherapy program. These students were administered a two-stage, 33-item radiation protection knowledge scale via Google Forms before and after the application course. The application results were analyzed as pre-test and post-test. Results and Discussion: A total of 116 students participated in the study. According to the study results, there was a difference in the students' awareness of the radiation protection sub-factor before and after the application. The primary reason for this is that observing the use of protective equipment during the application has increased their awareness. The importance of protective equipment for both worker health and patient safety has been understood. Conclusion: This study demonstrated the necessity of recording and monitoring radiation exposure during diagnosis and treatment procedures. The need to implement safety protocols to minimize the potential consequences of radiation hazards has also been recognized.Öğe From unmet childhood needs to parenting attitudes: breaking the cycle(Taylor and Francis, 2025)Objective: Rooted in Schema Therapy, this research posits that unmet physiological, social, and psychological needs during early life contribute to the development of enduring cognitive frameworks, termed early maladaptive schemas (EMS), which influence affect, behaviour, and cognition across the lifespan. Accordingly, the objective was to examine whether EMSs are systematically associated with specific parenting attitudes (PAs). Method: This correlational study employed a concurrent design. Participants included 246 volunteer parents of preschool-aged children residing in a cosmopolitan district of Istanbul. Data were collected online using validated measures of EMS and PA, along with additional items assessing potential confounding variables. Results: Correlational analyses revealed moderate positive associations between EMS and authoritarian parenting attitudes and moderate negative associations with democratic parenting attitudes. Hierarchical regression analyses showed that EMS accounted for over 20% of the variance in parenting attitudes, with socioeconomic status and education emerging as significant moderators. Discussion: EMSs significantly predict parenting attitudes, increasing authoritarian attitudes, and reducing democratic ones. Early identification of EMS, combined with schema-focused interventions and evidence-based parent education programs may help disrupt maladaptive parenting cycles and promote healthier parent–child dynamics.Öğe The Effect of Osteopathic Manipulative Treatment Adjunct on Stabilization Splint Treatment in Temporomandibular Joint Anterior Disc Displacement with Reduction Disorder: A Quantitative Analysis, Pilot Study(MDPI, 2025) Aklar, Ayca; Bal, Burcu; Tasdelen, Neslihan; Ertas, GokhanObjective: This study aimed to quantitatively assess the efficacy of osteopathic manipulative treatment (OMT) as an adjunct to stabilization splint treatment for temporomandibular joint anterior disc displacement with reduction (ADDwR) disorder. Method: Thirty-eight joints were evaluated in this study. OMT, in addition to splint treatment, was administered to the study group, and the control group only received splint treatment. Before and after the treatments, the quality of life, the pain levels of distinct body regions, and the sleep quality were evaluated, while mandibular movements were assessed and condyle–disc position differences measured on magnetic resonance images. Results: In all the life qualities, except social functionality, increases after treatment were present for both control and study groups, but the increase was significant in bodily pain for the control group (p = 0.034) while increases were significant in physical functionality (p = 0.018), general health perception (p = 0.027), and reported health transition (p = 0.019) for the study group. Significant pain reduction in all body regions was seen in the study groups (p = 0.007–0.033), but the decrease was only significant for the temporomandibular joint for the control group (p = 0.011). The sleep quality significantly improved for the study group (p = 0.018). Limited after-treatment improvements in the condyle–disc positions were determined for both the normal joints and joints with ADDwR in the study group. Conclusions: The application of OMT adjunct to splint treatment increases quality of life and sleep, reduces bodily pain, and improves condyle–disc positions over the MRIs of TMJ.Öğe Does inspiratory muscle training affect expiratory muscle thickness in respiratory intensive care patients? A pilot randomized controlled study(W B SAUNDERS CO-ELSEVIER INC, 2025) Benli, Reyhan Kaygusuz; Yilmaz, Baris; Yurdalan, S. UfukBackground: This randomized controlled trial aimed to compare abdominal muscle thickness between intensive care patients and healthy controls, and to evaluate the impact of IMT on expiratory muscle thickness using ultrasound. Methods: In this single-blind randomized controlled trial, 20 post-extubation intensive care patients were randomly assigned to either an a conventional physiotherapy (CP) group or IMT + CP group. Both interventions were applied for five days. An additional 10 healthy individuals served as controls for comparison. Abdominal muscle thicknesses-including external oblique (EOA), internal oblique (IOA), transversus abdominis (TRA), and rectus abdominis (RA)-were measured using ultrasound. Maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) were also recorded. Results: At baseline, healthy controls had significantly higher MIP, MIP% predicted, MEP, MEP% predicted, and RA muscle thickness compared to both patient groups (p < 0.05). Following intervention, both IMT and CP groups showed significant improvements in MIP (p < 0.05), but only the IMT group demonstrated significant increases in MEP, MEP% predicted, IOA, and RA muscle thickness (p < 0.05). The IMT group showed significantly greater improvements in MIP, MEP, IOA, and RA muscle thickness compared to the CP group (p < 0.05). Conclusion: Post-extubation IMT may improve not only inspiratory but also expiratory muscle strength and abdominal wall thickness. These findings suggest that IMT could support weaning processes in intensive care, although larger studies are needed.Öğe Skeletal muscle alterations in type 2 diabetes mellitus with and without dyslipidemia(BioMed Central Ltd, 2025) Satman, Ilhan; Dayican, Damla Korkmaz; Calikoglu, Fulya; Sahin, Humeyra Rekali; Perone, Francesco; Akinci, BuketBackground Diabetic dyslipidemia, a common comorbidity in people with type 2 diabetes, has been reported to be associated with adverse metabolic outcomes. Skeletal muscle is a key organ impacted by metabolic disorders; however, the specific effects of diabetic dyslipidemia on skeletal muscle mass, strength, and performance remain unclear. The aim of this study was to assess the skeletal muscle alterations of people with type 2 diabetes with and without dyslipidemia. Methods This retrospective study included 144 participants (mean age 51.3 +/- 7.1 years; 103 female, 41 male) aged 40-65 years. Body composition was assessed using bioelectrical impedance analysis (BIA), muscle strength via dynamometer, and functional capacity with the 6-minute walk test (6MWT). To minimize the confounding effect of longer diabetes duration in the diabetic dyslipidemia group, propensity score matching (PSM) was performed using a 1:1 nearest-neighbor method. All analyses were performed on matched groups. ROC analysis was conducted for variables showing significant differences. Results After PSM, people with diabetic dyslipidemia showed significantly lower skeletal muscle mass and skeletal muscle index (SMI), higher body fat percentage, and reduced 6MWD compared to those with diabetes alone (p < 0.05). In women with diabetic dyslipidemia, handgrip strength was significantly lower. ROC analysis revealed moderate predictive value for skeletal muscle mass (AUC = 0.682), SMI (AUC = 0.654), and 6MWD (AUC = 0.628). Conclusion This study demonstrated that people with diabetic dyslipidemia had lower skeletal muscle mass, SMI, and decreased physical performance compared to people with diabetes alone, even after matching for diabetes duration. These findings demonstrate early sarcopenic and dynapenic changes and highlight the need to consider skeletal muscle health and lipid abnormalities together in diabetes management.Öğe Volumetric Three-Dimensional Evaluation of the Pharyngeal Airway After Orthognathic Surgery in Patients with Skeletal Class III Malocclusion(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Oz, Aslihan Zeynep; El, Hakan; Palomo, Juan MartinBackground: Orthognathic surgery significantly alters the dimensions of the pharyngeal airway. This study's objective was to assess alterations in the pharyngeal airway volume via cone-beam computed tomography (CBCT) after orthognathic surgery in patients with skeletal Class III malocclusion. Methods: This retrospective study analyzed CBCT images from 23 patients with skeletal Class III malocclusion (13 females, 10 males), who were categorized into two groups based on the surgical approach: double-jaw and single-jaw surgery. The double-jaw group included 13 patients who underwent bilateral sagittal split osteotomy (BSSO) and Le Fort I osteotomy, whereas the single-jaw group included of 10 patients who had underwent BSSO only. CBCT images were evaluated both before surgery and at a minimum of three months after surgery. The oropharyngeal volume (OP), nasopharyngeal volume (NP), total airway volume, posterior airway space (PAS), and the most constricted area at the base of the tongue (minAx) were measured. Statistical analyses were performed using either paired t-tests or Wilcoxon signed-rank tests depending on data normality, with a significance level set at p < 0.01. Results: In the double-jaw group, a significant volumetric increase was observed in the nasopharynx (5316 +/- 1948 mm(3) to 6064 +/- 1899 mm(3); p = 0.010) and oropharyngeal volume decreased from 17,097 +/- 5675 mm(3) to 14,290 +/- 5835 mm(3); however, this reduction was not statistically significant (p = 0.017). In contrast, the single-jaw group showed a significant reduction in oropharyngeal volume from 15,620 +/- 5040 mm(3) to 12,444 +/- 4701 mm(3) (p = 0.010), with no significant change in nasopharyngeal volume (p = 0.551). Total airway volume significantly decreased only in the single-jaw group (from 20,452 +/- 7754 mm(3) to 16,846 +/- 6529 mm(3), p = 0.010). Additionally, both groups exhibited marked decreases in PAS and minimum axial area values (all p < 0.01). Conclusions: Orthognathic surgery led to a significant volumetric increase in the nasopharynx in the double-jaw group, whereas the oropharynx volume significantly decreased only in the single-jaw group. Additionally, both surgical approaches resulted in a marked reduction in PAS and minimum axial area values, highlighting a notable impact on posterior airway dimensions.Öğe Cross-Cultural Adaptation and Validation of the Dance Functional Outcome Survey for Turkish Dancers (DFOS-TR)(CIENCE & MEDICINE INC, 2025) Tekin, Demet; Agopyan, Ani; Bronner, ShawIn dance, injuries are significant factors that can bring an active dance career to an end. A patient-reported outcomes questionnaire with established validity and reliability is useful for determining and evaluating the functional status of dancers before or after injuries. However, no valid and reliable survey is available in Turkish to assess dancers' functionality levels. The objective of this study was to translate, culturally adapt, and validate the characteristics of the Turkish version of the Dance Functional Outcome Survey (DFOS-TR) in adult dancers. METHODS: The DFOS-TR underwent forward translation, reconciliation, backward translation, and thorough review by an expert committee to ensure optimal alignment with the original English DFOS. A sample of 113 dancers (55 injured and 58 healthy) voluntarily participated in the research. Construct validity was assessed by comparing DFOS-TR to SF-36 using Pearson correlations; exploratory factor analysis and internal consistency were conducted; and sensitivity was evaluated through the generation of receiver operating characteristic curves and calculation of the area under the curve (AUC). Test-retest reliability was assessed by examining 26 dancers over a 15-day period, employing intraclass correlation (ICC). Various methods were employed, including ICC, standard error of measurement (SEM), minimal detectable change at the 95% confidence interval (MDC95), and standardized response mean (SRM). DFOS-TR scores were compared using paired samples t-test and two-way repeated measures ANOVA (p<0.05). The scores of injured dancers were examined to identify any floor or ceiling effects. RESULTS: The DFOS-TR demonstrated very high test-retest reliability (ICC=0.84). Single-factor loading in exploratory factor analysis confirmed the scale's unidimensionality and high internal consistency (a=0.79), A positive moderate correlation was found between SF-36 physical component and DFOS-TR total score (r=0.44; p=0.046) and activities of daily living (ADL) subscore (r=0.58; p=0.006). Cut-off value of 85.5 for DFOS-TR total score yielded in 87.3% sensitivity and 36.2% specificity. The scale did not exhibit ceiling or floor effects among the injured dancers, indicating robust measurement properties. CONCLUSION: The DFOS-TR can be used as a reliable, internally consistent, and effective measurement tool for Turkish-speaking dancers in health as well as during and after lumbar or lower extremity injuries.Öğe Mental Health in a Digital World: How Problematic Cell Phone Use and Personality Predict Fear of Missing Out (FoMO) in Gen Z University Students from Türkiye and the U.S.(YERKURE TANITIM & YAYINCILIK HIZMETLERI A.S, 2025) Yüksel,Peri; Huiqiao, HouObjective: The authors sought to examine the association between Fear of Missing Out (FoMO), mental health, personality traits, and social media use among Turkish and U.S. university students, belonging to Generation Z (Gen Z), born between 1997 and 2012, a cohort deeply immersed in technology and social media from an early age. Methods: The present online survey study included 637 university students aged 18-25 (20.09% male, 78.65% female, 1.26% other) from T & uuml;rkiye (86.03%) and the US (14.97%). Participants completed 19 sociodemographic questions, a 17-item FoMO Scale, and a 44-item Personality Inventory. The study analyzed the relationship between FoMO, mental health, personality traits, and social media use across different platforms. Results: Findings revealed that frequent cell phone use and higher FoMO scores were significantly associated with problematic social media use. TikTok users reported higher FoMO compared to non-users. Additionally, there was a positive correlation between the number of social media platforms used and FoMO. Social media use driven by boredom and passive observation further increased FoMO. Associations between FoMO and personality traits highlighted the role of individual differences in social media behaviors. Conclusion: The study highlights the need for tailored interventions that address both social media usage patterns and personality traits to reduce the negative impact of FoMO on mental health. While Gen Z are digital natives, they need to become digital experts to navigate the mental health challenges exacerbated by curated content and the prevalence of FoMO on social media. Universities play a crucial role in raising awareness and supporting students in managing these psychological pressures by promoting balanced digital behaviors. A deeper understanding of the interplay between digital behaviors, personality traits, and cultural contexts can inform future interventions aimed at reducing FoMO and enhancing the well-being of young people in an increasingly interconnected world.
