Predicting IDF Through Discrete Cosine Transform-Based Machine Learning and Honey Formation Optimization: A Case Study of the Göksu River Basin
No full textThis study investigates three approaches for modeling intensity-duration-frequency (IDF) relationships of precipitation in the Göksu River Basin. The first approach applies statistical frequency analysis at eight stations for 14 precipitation durations using five probability distributions (Gumbel, Log-Normal, GEV, Pearson III, and Log-Pearson III) with three parameter estimation methods (PWM, MLE, MOM). The best distributions were selected via Kolmogorov-Smirnov and Chi-Square tests. The second approach employs machine learning (ML) models, including standalone and hybrid models enhanced with the Discrete Cosine Transform (DCT), trained on data from six stations. The third method uses 11 empirical IDF equations optimized through the Honey Formation Optimization (HFO) algorithm. The study's novelty lies in combining DCT-enhanced ML and HFO for IDF prediction, specifically applied to the Göksu Basin. Model performance at the Mut and Silifke stations was evaluated using MAE, RMSE, R2, Performance Index, Pearson Correlation, and Mean of Min/Max error. Results revealed that the DCT-based Least Squares Boosting (LSBoost-DCT) model achieved the best accuracy, with MAE (15.83, 30.49) and RMSE (27.47, 48.19) values, reducing errors by up to 42% and 37%. Overall, integrating DCT with ML substantially improved IDF prediction accuracy, providing a robust framework for future hydrological research. © 2025 The Authors
Strategic Solutions for Women’s Empowerment Through Islamic Social Finance in Light of Maqāṣid Syarī’ah: A Delphi-ANP Approach
No full textWomen in Indonesia continue to face challenges in achieving economic and social independence. In fact, in Islamic law's framework, particularly Maqāṣid Syarī’ah's, Islamic Social Finance (ISF) emerges as a pivotal instrument for advancing women's empowerment. This study aims to identify key problems and strategic solutions for women's empowerment through Islamic social finance while predicting the future direction of empowerment itself. Utilizing the Delphi Analytical Network Process, this research conducted literature reviews, focus group discussions, and expert interviews across academia, practice, and regulatory bodies. The findings highlight critical problems from three dimensions for enhancing women's welfare: women's limited time since they have multiple roles (wife and mother) (0.116), capital provision from Islamic social finance institutions without assistance (0.200), and lack of shared information to muzakkī/donors on the importance of empowering women (0.315). Key strategic solutions include addressing essential needs prior to empowerment (0.054), customizing programs to recipients' interests (0.053), and providing financial literacy training (0.052). For Islamic social finance institutions, priorities include creating a comprehensive empowerment framework (0.137), fostering collaborations (0.128), and enhancing institutional capacities (0.115). Improving funding transparency (0.315) and channeling funds through institutions (0.221) are crucial in donor engagement. © (c) 2025 by Al-Ihkam, Jurnal Hukum dan Pranata Sosial
The Effect of Virtual Reality Applied During Blood Draw on Pain and Anxiety in Adults: Controlled Study
No full textPurpose: The purpose of this study is to determine the effect of using virtual reality (VR) during blood draw on pain and anxiety levels in adults. Material and Methods: This study was conducted at the blood collection unit of a medicine faculty hospital in central of Anatolia in T & uuml;rkiye using a randomized controlled experimental design. The study sample consisted of a total of 76 adult patients, with 38 in the VR group and 38 in the control group. The patients were assigned to groups using block randomization method. Data were collected using the Visual Analog Scale (VAS) and State-Trait Anxiety Inventory (STAI). While patients in VR group watched with nature images through VR googles during the blood draw, the control group received only the routine blood draw procedure. STAI scores of patients in both groups were measured before and after the procedure, along with VAS scores during the procedure. Results: It was found that the VR group had statistically significantly lower mean VAS and STAI scores compared to the control group (p<0.05). Conclusion: In line with these results, it can be said that the use of virtual reality during blood draw is effective in reducing pain and anxiety levels in adult patients
Flood Modeling in Samsun Engiz Stream: Evaluation of the Adequacy of River Sections With HEC-RAS
No full textFloods pose a significant threat to communities, particularly in Turkey's Central Black Sea Region, where they cause widespread economic, social, and environmental damage. The Ondokuzmayis district of Samsun has been especially vulnerable to recurrent flooding, emphasizing the need for precise risk assessments and effective flood management strategies. In this study, the flood modelling of Engiz Stream, located in the Ondokuzmayis district of Samsun, was conducted using one-dimensional modeling due to its speed, low computational cost and ease of implementation. Hydraulic modeling was performed in HEC-RAS using flow data from Ballıca Station on Engiz Stream and statistical distributions from the EasyFit software library. In the study, flow rates for 25, 50, 100, and 500-year flood return periods (Q25: 431 m³/s, Q50: 479.87 m³/s, Q100: 531.75 m³/s, Q500: 665.37 m³/s) were calculated, and the flow was modeled using a 5-meter resolution digital surface model. The modeling results indicated that while the cross-sections in urban areas were adequate, the river cross-sections in the agricultural areas where the river flows into the Black Sea were insufficient for the Q25 flow rate and beyond. © 2025 by the authors
Gençlerde Teknoloji Bağımlılığı, Siber Mağduriyet, Siber Zorbalık ve Benlik Saygısı Arasındaki Karmaşık Bağlantının Çözümü
No full textÇalışma, gençler arasında teknoloji bağımlılığı, siber zorbalık, siber kurbanlık ve öz saygı arasındaki karmaşık ilişkileri incelemiştir. Örneklem, Konya’daki üniversitelerden farklı sosyoekonomik düzeylere sahip, çoğunluğu kadın olan 335 lisans öğrencisinden oluşmuştur. Sosyal medya, web sayfaları, dijital uygulamalar ve çevrimiçi oyunlarda geçirilen zaman gibi tanımlayıcı faktörleri incelemiş ve bu faktörlerin öngörücü gücünü korelasyon ve hiyerarşik regresyon analizleri aracılığıyla değerlendirmiştir. Bulgular, öz saygının doğrudan siber zorbalığı tahmin etmediğini, çevrimiçi oyun bağımlılığı ve siber kurbanlığın daha önemli tahmin ediciler olduğunu ortaya koymaktadır. Sürekli oyun oynama alışkanlığına sahip öğrencilerin teknoloji bağımlılığı puanları daha yüksek gözlemlenmiştir. Ayrıca, erkekler siber zorbalık ve siber kurbanlık için daha yüksek ortalama puanlar gösterirken, kadınların öz saygı için anlamlı derecede daha yüksek ortalama puanları olduğu tespit edilmiştir. Sürekli oyun oynayanlar ve sosyal medya üyeleri, siber zorbalık ve siber kurbanlık için daha yüksek ortalama puanlar sergilemiştir. Son olarak, siber kurbanlık, öz saygı ile teknoloji bağımlılığı arasındaki ilişkiyi anlamlı bir şekilde aracılık etmektedir; bu da siber kurbanlığın ele alınmasının öz saygıyı dolaylı olarak artırabileceği ve teknoloji bağımlılığını azaltabileceğini önermektedir. Çalışmanın sınırlılıkları arasında çalışmanın tanımlayıcı doğası ve başa çıkma mekanizmaları ile stres seviyeleri için ölçümlerin eksikliği yer almaktadır. Çalışma, bu olguların farklı yaş grupları arasındaki uzunlamasına özelliklerini anlamak için daha kapsamlı analizlere ihtiyaç duyulduğunu vurgulamaktadır.This study examined the complex relationships between technology addiction, cyberbullying, cyber victimization, and self-esteem among young individuals. The sample consisted of 335 undergraduate students—mostly female—from universities in Konya with diverse socioeconomic backgrounds. The study analyzed descriptive factors such as time spent on social media, websites, digital applications, and online gaming and assessed their predictive power through correlation and hierarchical regression analyses. Findings revealed that self-esteem did not directly predict cyberbullying, while online gaming addiction and cyber victimization emerged as more significant predictors. Students with habitual gaming behavior exhibited higher technology addiction scores. Additionally, male participants showed significantly higher mean scores for both cyberbullying and cyber victimization, whereas female participants had significantly higher mean scores for self-esteem. Those who regularly played games or used social media also reported higher levels of cyberbullying and victimization. Importantly, the study found that cyber victimization significantly mediated the relationship between self-esteem and technology addiction, suggesting that addressing cyber victimization may indirectly enhance self-esteem and reduce technology dependency. The study’s limitations include its descriptive nature and the absence of measures related to coping mechanisms and stress levels. The study emphasizes the need for more comprehensive analyses to understand the longitudinal characteristics of these phenomena across different age groups

Contributions of University Students’ Cognitions Towards the University to the Creation of a Sustainable University
No full textIn almost all institutional discourses about universities, students are mentioned. Universities are defined as dynamic areas that pave the way for students to acquire and develop scientifically based professional skills. Students are also given importance in explanations about creating a sustainable university. However, their contributions have been neglected in the development of this idea. Based on this inspiration, this study aims to examine the kind of expansions the university reality constructed by university students with their cognitive patterns can provide to the idea of creating a sustainable university. To achieve this aim, firstly, the university reality constructed by students enrolled in an associate degree program at a university, with their cognitive patterns, is explained through metaphors. Accordingly, open-ended questions were asked to 200 university students who were in the process of experiencing university life and volunteered to participate in the study. The answers received were evaluated through descriptive analysis and content analysis. As a result of the research, it was seen that 119 metaphors were produced, and these metaphors could be divided into seven categories with the titles of university as a structure that expresses, develops, and enlightens university reality; university as a structure that reaches goals; university as a social life area that accommodates differences and offers diversity; university as a structure that limits; university as a structure that challenges; university as a structure that liberates; and university as a structure that provides security and peace. Then, it was discussed how university students’ explanations about university reality would benefit the establishment of a sustainable university. While this study provides insights into university students’ perspectives on the university, it also contributes to strengthening and expanding the existing idea of a sustainable university
Developing and Validating a Scale for Assessing Teachers’ Attitudes Toward Project Consultancy
No full textThis study addresses a critical gap in educational research by developing a valid and reliable scale to measure teachers’ attitudes
toward project consultancy an increasingly significant role in project-based learning environments. Despite the growing
importance of teacher involvement in guiding student projects, tools for assessing teachers’ consultancy attitudes remain limited.
Using an exploratory sequential mixed-methods design, the study began with semi-structured interviews (n = 10) to
identify core themes, leading to the creation of an item pool. A preliminary version of the scale was administered to 382
teachers for Exploratory Factor Analysis (EFA), revealing a four-factor structure—evaluation, execution, planning, and
completion—explaining 61.9% of the variance. Confirmatory Factor Analysis (CFA) with a separate sample (n = 194) confirmed
the model fit (x2/df = 2.4, CFI = 0.92, RMSEA = 0.08). The final 20-item scale demonstrated strong internal consistency
(a = .89). Notably, female teachers scored significantly higher than male teachers on the evaluation subdimension. The
Project Consultancy Attitude Scale offers researchers and educational practitioners a psychometrically sound instrument to
evaluate and support teacher development in project-based learning contex
