Examination of the Mental Health Status of University Students Directly or Indirectly Affected by the Earthquake
(SAGE Publications Inc., 2025) Ayık, Y.; Kaya, H.; Sarısahin, S.; Ozturk, B.; Kayıhan, H.
Objective: This study examines the mental health status of university students directly affected by the earthquake in the disaster zone and those indirectly affected by being outside the earthquake zone during the Kahramanmaraş earthquake that struck Turkey on February 6, 2023. Methods: A total of 109 students from 37 universities in 24 cities participated. Data were collected using an online survey that included a Demographic Information Form, the Impact of Event Scale-Revised (IES-R), the Earthquake Anxiety Scale, the DSM-5 PTSD checklist, and the Depression-Anxiety-Stress Scale-21. Mental health outcomes of directly and indirectly affected students were compared. Results: Students directly affected showed significantly higher levels of post-traumatic stress disorder (PTSD), depression, anxiety, and earthquake-related anxiety. Among indirectly affected students, females reported higher IES-R, PTSD, and earthquake anxiety scores than males. Regression analysis identified factors such as earthquake exposure, loss of relatives, involvement in search and rescue, and relocation as linked to adverse mental health outcomes. Conclusion: Although students directly affected by the earthquake are at greater risk for PTSD, depression, and anxiety, both groups face significant mental health problems. As these effects may be ongoing rather than temporary, the role of occupational therapy in promoting occupational engagement and mental health in disaster management is noteworthy. © The Author(s) 2025

Universal Design Approach To Analysis of Physical Environment for Users With Multiple Sclerosis
(Universitat Politecnica de Catalunya, 2022) Çakır, H.S.; Tosun, A.
The concept of Universal Design aims for the utilization of every product and environment for every individual without the need for further adaptation. The frequent occurrence of Multiple Sclerosis (MS) in societies has necessitated a more innovative and exploratory approach to the field of design. Many of the products and built environments encountered by individuals with MS in their daily lives fall short in terms of meeting safety and accessibility needs. It is essential to establish the correct design approach so that users with MS can meet their needs easily and safely without depending on others. In this research, the problems encountered by users with MS in their residences were evaluated within the framework of Universal Design principles, and design recommendations were stated using a sample case in Turkey. Throughout the study, accessibility challenges, mobility, fatigue and balance problems, vision and lighting conditions, climatization and noise sensitivity, and psychological issues were primarily considered. The residence of the sample user with MS was examined in detail, and an in-depth interview was conducted during the research. The difficulties and life routines of the user with MS were observed and identified. Home design solutions associated with Universal Design principles were represented so that the users with MS have safe and accessible housing regarding their physiological and psychological conditions. The highlighted proposals may contribute to architectural design to make modifications for comfortable and safe housing in related cases having similar symptoms with MS. Future research can benefit from these findings and proposals to provide innovative approaches, develop policies, and conduct interdisciplinary studies on related design issues. © 2022, Universitat Politecnica de Catalunya.

Political Discourse on Syrian Refugees in Turkey
(Peter Lang AG, 2021) Yiğit, M.H.; Uyar, C.
This chapter focuses on a comparative research investigation on how populist discourse and securitization on refugees are constituted by partners of political power. The analysis argues that refugees are instrumentalized in domestic/ foreign politics by exposure to exclusionary rhetoric by political parties in Turkey as of 2018. In the context of the research, the official political discourses and statements of five parties during 2018 general and 2019 local election campaigns, the election manifestos, and post-February 2020 Idlib incident were examined. The political parties are AKP, CHP, MHP, İYİ Party, and HDP. In this context, how and for what purposes refugees are securitized with populist rhetoric are examined accordingly. For this analysis, the usage and content of the terms “Syrian, " “refugee, " “immigrant, " “asylum, " and “under temporary protection” were investigated. © Peter Lang GmbH Internationaler Verlag der Wissenschaften Berlin 2021.
Women’s Self-Transcendence Levels After a Cesarean Birth and Its Contributing Variables
(Jordan University of Science and Technology, 2025) Abushaikha, Lubna A.; Abdel Razeq, Nadin M.; Abushaikha, Fadwa A.
Background: A Cesarean birth has significant implications for women’s physical and psychological health. However, limited studies have explored self-transcendence, as a measure of well-being, and its contributing variables during the postpartum period. Purpose: This study aimed to determine the levels of self-transcendence among women after a Cesarean birth and to explore the contribution of demographic and obstetric variables. Methods: This descriptive correlational study used a convenient sample of 232 women (aged 19-49 years) who completed questionnaires in teaching and private hospitals. Results: Overall, 55% (n=128) of women had high levels of self-transcendence, with a mean score of 45.8 (SD=6.1) out of 60. Self-transcendence was negatively correlated with the number of Cesarean births (r=-0.21, p < 0.001). Higher self-transcendence levels were found among women who gave birth at private hospitals (rpb= 0.41, p < 0.001). Conclusion: A Cesarean birth can be an opportunity for self-transcendence and psychological well-being for women, depending on demographic and obstetric variables. Implications for Nursing: The findings of this study may inform healthcare professionals, especially maternity nurses, in understanding psychological dimensions associated with Cesarean birth. © 2025 Elsevier B.V., All rights reserved.

This study presents drivers and barriers on construction industry extended reality (XR) implementations in Turkey. It aims to investigate the current state and future directions of XR opportunities for architecture offices and construction companies in a developing country. A quantitative approach was employed which involves conducting a survey, performing statistical analyses, and verification of the hypotheses. The data were analyzed by SPSS and Excel using the frequency, mean score, standard deviation (SD), and one sample t-test. Thirty-three different companies participated in the survey with a return rate of 56.89%. The results were considered statistically significant since all the p-values were below 0.05. The findings revealed that even though 60% of the companies are not using XR, 60% companies have near future plans on implementing them. According to the results, XR was considered as beneficial and highly motivating for the near future, yet it needs to be widespread for companies to keep themselves abreast of information and communication technology trends. Finally, by considering the findings obtained from the results this study reaches a classification of drivers as 'increased efficiency: time-cost-quality' and 'increased communication and coordination' while barriers as 'technical limitations', 'high costs', and 'unqualified professional'.
Panax Ginseng Extract Ameliorates Methotrexate-Induced Multi-Organ Damage Via the Regulation of Oxidative Stress
(Marmara Univ, 2023) Macit, Caglar; Ede-Pazarbasi, Seren; Yilmaz-karaoglu, Suemeyye; Tunali-Akbay, Tugba; Karakaya-Cimen, Fatma Bedia; Ercan, Feriha; Sener, Goksel
Oxidative damage plays an important role in organ toxicities caused by methotrexate (MTX). This study aimed to determine the antioxidant effects of Panax ginseng (PxG) extract against MTX-induced liver, lung, ileum and kidney damage. Twenty-four Sprague Dawley male rats (weight 250-300 g) were used in the study. The animals were randomly separated into three groups: a) Control, b) MTX-treated (MTX) and c) MTX+PxG-treated (MTX+PxG) groups. MTX was administered intraperitoneally at 20 mg/kg, as a single dose to MTX and MTX+PxG groups. PxG was administered orally at 100 mg/kg to the MTX+PxG group for five days. Saline was given to the control and MTX groups for 5 days. At the end of the experiment, liver, lung, ileum, and kidney samples were obtained. Malondialdehyde (MDA) and glutathione (GSH) levels, superoxide dismutase (SOD), glutathione-S-transferase (GST) and tissue factor (TF) activities were determined in all tissues. In addition, histological examinations were done through light microscopy. GraphPad Prism 5v. was used for statistics, and p<0.05 were considered significant. Administration of MTX caused severe injury in tissues. Findings showed that MDA level, SOD, and GST activities were significantly normalized in the MTX+PxG group compared to the control group. A significant reduction in GSH level observed in the MTX group was reversed with PxG administration In addition, TF activity and total protein levels were found to be impaired in the MTX group, but TF activity was significantly improved in liver and lung tissues and total protein level was significantly reversed in lung and ileum in MTX+PxG group. The results of histological examinations showed that MTX-induced damage was ameliorated with the PxG administration. In conclusion, this study shows that Panax ginseng, thanks to its antioxidant properties, reversed MTX-induced tissue damage and therefore may be beneficial against side effects in patients undergoing chemotherapy.

Problems and Insights on Space: the Effects of Phenomenology Theory on the Concept of Space
(Yildiz Technical Univ, Fac Architecture, 2020) Ulubay, Serhat; Onal, Feride
This study was an examination of a change in the means and manner of comprehension of the concept of space and the questions it stimulated as a result of the emergence and development of phenomenology theory in the last century. Phenomenology theory is based on the argument that our understanding of phenomena is related to our consciousness and promotes a different and deeper form of comprehension by asking questions about the essence of existence. The movement grew in the early 20th century, and challenged the dominant view of rational reality and Cartesian assumptions. Phenomenology encourages questioning what has been defined as concrete and immutable, arguing that phenomena can be grasped through internal experience rather than simply visible physical appearance and predefined ideas. According to this new concept, all of our acquisitions we call "experience" help us make sense of phenomena. Science makes its inquiries based on adopted and accepted experiences about the world. However, the phenomenological approach suggests that all adopted data, including the fundamentals of science, should also be questioned. The essential objective of the phenomenological philosophy is the extension of the field of questioning to explore the essence of facts and primary phenomena. This radical questioning deeply affected and altered the intellectual agenda of the time. Philosophers discussed and examined the intrinic meaning of many phenomena. The concept of space lends itself to this new kind of assessment. Phenomenology theory, which aims to contribute to the base of scientific knowledge and to increase the critical foundations of philosophy, opened the prevailing semantics of space perceived as an object defined with rational boundaries and mathematical assumptions to discussion. Phenomenological opinion, contrary to the Cartesian way of thinking, argues that space cannot be deliniated by the patterns of a single reality and that an infinite number of descriptors that we discover through our acts and experiences can be applied. This vision of space is discovered through all of our direct life experiences and queries of all realms, including the social and cultural arenas, psychology and the human body, ideas of the self and the question of existence, as well as hard science. Different methodologies applied by philosophers of the phenomenology school of thought diversified the basis of questioning and definition, and thereby enriched the concept of space. This study examines the methods of reading and questioning the definition of space used by phenomenological theorists and the contributions this interpretation brought to the conceptualization of space. The critical approach of the Cartesian way of thinking was compared and contrasted with the phenomenological view. All of the acquisitions and dynamics of life are in a state of constant change. The structure of societies, the way they comprehend the world, cultural and individual mental acts are not fixed like a photograph pausing a moment. A Cartesian view considers space to be a static and frozen object. A primary contribution of phenomenology to the intellectual environment of the last century was to encourage exploration of the fact that the mode of questioning has no boundaries, that the accepted realities cannot constitute the only starting point of our questioning. In addition, it reminded us that all our social and individual experiences are a means to grasp and comprehend the concept of space. We exist in this world through our thoughts, perceptions, memory, and body; therefore, we can comprehend phenomena, including space, via all of our life experience. This study examined how the idea of space has been shaped over time, focusing on the principles of phenomenological questioning and sixteen theorists considered pioneers of this way of thinking. The questioning put forward by phenomenology changes kinetically, and it is possible that such theories of the evaluation of space can be a tool for the diversification of today's thought on the subject and the discovery of news ideas of space.
The Effects of Chard Extract Against Streptozotocin-Induced Erectile Dysfunction in Rats
(Istanbul Univ, Fac Pharmacy, 2024) Aydin, Mustafa; Sacan, Ozlem; Kabasakal, Levent; Cetinel, Sule; Kadihasanoglu, Mustafa; Kendirci, Muammer; Sener, Goksel
Background and Aims: To analyze the potential therapeutic effects of chard against streptozotocin (STZ) -induced erectile dysfunction (ED) and oxidative damage in the corpus cavernousum in rats. Materials and Methods: In this study, Sprague-Dawley rats (250-300g) were allocated into groups as follows: control, diabetic, diabetic + chard, and diabetic + insulin. In order to induce diabetes, rats were given 65 mg/kg intraperitoneal streptozotocin. Chard extract was given orally at a dose 2 g/kg for 45 days beginning on 15 th days. Sixty days after STZ injection, intracavernosal pressure (ICP) was measured and rats were decapitated. Blood samples were obtained for glucose, asymmetric dimethylarginine (ADMA)levels, and lactate dehydrogenase (LDH) activity while cavernous tissues were taken to analyze luminol and lucigenin chemiluminescence (CL), malondialdehyde and glutathione and along with histological analysis. Results: The results revealed that diabetes caused significant decreases in cavernosal tissue glutathione levels, while luminol and lucigenin CL, and malondialdehyde levels were significantly elevated. Plasma glucose, ADMA levels, and LDH activity were also found to be increased in diabetic group. On the other hand, both chard extract and insulin treatment reversed these biochemical parameters significantly. Furthermore, it was found that the ICP value examined for evaluating erectile functions were lower in the diabetic group, but increased in both treatment groups which were similar to the control values. Conclusion: According to our results, chard extract, similar to insulin, reduced diabetes -induced oxidative damage in cavernosal tissue and protected erectile functions. This effects may be attributed its hypoglycemic and antioxidant properties.

Lower Urinary Tract Symptoms and Toileting Behaviors in Turkish Adult Women
(Routledge Journals, Taylor & Francis Ltd, 2023) Celenay, Seyda Toprak; Dusgun, Elif Sena; Karaaslan, Yasemin; Urus, Gulcin; Karadag, Mehmet; Ozdemir, Enver
This study aimed to investigate lower urinary tract symptoms (LUTS) in Turkish adult women and to compare toileting behaviors in women with and without LUTS. This cross-sectional study was conducted in 815 women. The International Consultation on Incontinence Modular Questionnaire - Female LUTS and a toileting behaviors form, created by the authors, were used in evaluations. Nearly 50 % of the women had at least one LUTS, 45.8 % had storage symptoms, 7.4 % had voiding symptoms, and 20.2 % had incontinence symptoms. The rates of premature urination, straining during urination, delayed urination, and sitting on the toilet while urinating were higher in women with LUTS than in women without LUTS (p < .05). The rate of squatting on the toilet while urinating was lower in women with LUTS than those without LUTS (p < .05). Various LUTS were common in adult women. Some toileting behaviors such as premature urination, straining during urination, delayed urination, and sitting on the toilet while urinating were higher in women with LUTS compared to women without LUTS. Since the rate of unhealthy toilet behaviors is higher in women with LUTS, it is important to know unhealthy toilet behaviors in the management of LUTS and to organize training programs to prevent these behaviors and LUTS.

(Springer Heidelberg, 2025) Bulut, Zeynep Irem; Unal, Edibe; Oksuz, Sevim; Dogru, Atalay; Akyol, Ahmet; Yakut, Yavuz
PurposeThis study was planned to test whether the Cognitive Exercise Therapy Approach- Biopsychosocial Questionnaire (BETY-BQ) is an appropriate questionnaire in assessing the biopsychosocial status in KOA.MethodsFrequently used assessment tools, OA-specific scale The Western Ontario and McMaster Universities OA Index, the Hospital Anxiety and Depression Scale, and the Short Form-36 were utilized for the validity and responsiveness of BETY-BQ in individuals with KOA. The test-retest method, internal consistency analysis, and item analysis were used to test reliability. For the test-retest method, BETY-BQ was administered again to the same 30 individuals 1 week later. To assess the responsiveness of the BETY-BQ, individuals who underwent medical treatment were subjected to a second round of questionnaire administration after a 3-month interval.ResultsModerate to weak correlations between BETY-BQ and the other questionnaires ensued the divergent validity. According to the confirmatory factor analysis, all goodness-of-fit indices of BETY-BQ were acceptable (CMIN/df = 2.212; RMSEA = 0.080; SRMR = 0.08). Both Cronbach's alpha (0.900) and ICC value (0.941) showed that the BETY-BQ has excellent reliability in the KOA population. The Bland-Altman Plot showed high agreement as all differences between the first and second BETY-BQ were found between the 95% lower and upper limits. BETY-BQ demonstrated moderate responsiveness as the effect size and standardized mean response were 0.656 and 0.566, respectively.ConclusionA valid, reliable, responsive, multi-dimensional, and self-reported questionnaire for measuring biopsychosocial status in KOA was introduced to the use of healthcare professionals.

Evaluating the Potential Role of Ai Chatbots in Designing Personalized Exercise Programs for Weight Management
(Taylor & Francis inc, 2025) Sarac, Hakan; Ulusoy, Ismet Tarik; Alpay, Janset; Odemis, Hasan; Sogut, Mustafa
This study aimed to evaluate the effectiveness and potential use of artificial intelligence (AI) chatbots in developing personalized exercise programs for weight management. Exercise programs were developed by ChatGPT-4, ChatGPT-4o, Gemini-1.5 Pro models, and a group of human expert trainers for a hypothetical obese individual case. All exercise programs were assessed based on the American College of Sports Medicine (ACSM) and National Academy of Sports Medicine (NASM) guidelines. The chatbot-generated programs were consistent with ACSM and NASM standards, indicating their potential use in low-resource settings. Nevertheless, considerable differences were found between human trainers and chatbots in key parameters, including initial load and target heart rate zone recommendations. While AI chatbots have the potential to enhance accessibility, human expertise remains essential to ensure program safety and effectiveness. The results of this study provide insights into the potential role of AI chatbots in personalized exercise programs for weight management.

Acute Changes in Electrophysiological Brain Dynamics in Elite Karate Players
(Springer international Publishing Ag, 2020) Duru, Adil Deniz; Balcioglu, Taylan Hayri; Ozcan Cakir, Canan Elif; Goksel Duru, Dilek
Regular physical exercise has enhanced effects on the human anatomy and functionality. Recently, an effect of a single set of exercise is shown to have positive effects on mood and on cognitive functioning. The aim of this study is to investigate the effect of a single bout of moderate exercise on the brain electrophysiological dynamics in resting-state condition and under the mental workload situation from elite-level athletes. For this purpose, electroencephalogram (EEG) is measured before and after the exercise sessions from 17 elite karate players who are members of the national karate team of Turkey. Blood lactate measurements are implemented to monitor the volunteers before EEG measurements. EEG data are analyzed using three metrics: conventional band power of each electrode, coherence metrics between electrodes for each band and source coherence values corresponding to each frequency band. Each metric is statistically analyzed between pre- and post-values, and results revealed that in all frequency bands, right parietal electrode had increased connection values which are thought to be related to ongoing sympathetic nervous system response observed during the recovery period. Another finding is the enhanced connectivity of frontal sources under the resting state as well as during the increased mental workload periods.

A Fast Intrusion Detection System Based on Swift Wrapper Feature Selection and Speedy Ensemble Classifier
(Pergamon-elsevier Science Ltd, 2024) Zorarpaci, Ezgi
Due to the widespread use of the internet, computer network systems may be exposed to different types of attacks. For this reason, the intrusion detection systems (IDSs) are often used to protect the network systems. Network traffic data (i.e., network packets) includes many features. However, most of them are irrelevant and can lead to a decrease in the runtime and/or the detection performance of the IDS. Although various data mining methods have been applied to improve the effectiveness of IDS, research regarding IDSs having high detection rates and better runtime performance (i.e., lower computational cost) is ongoing. On the other hand, the dimensionality reduction techniques help to eliminate unnecessary features and reduce the computation time of a classification algorithm. In the literature, the feature selection methods (i.e., filter and wrapper) have been widely used for the dimensionality reduction in IDSs. Although the wrapper feature selection techniques outperform the filters, they are time-consuming. Again, the ensemble classifiers can achieve higher detection rates for IDSs compared to the stand-alone classifiers, but they require more computation time to build the model. In order to improve the runtime performance and the detection rate of IDS, a swift wrapper feature selection and a speedy ensemble classifier are proposed in this study. For the dimensionality reduction, the swift wrapper feature selection (i.e., DBDE-QDA) is used, which consists of dichotomous binary differential evolution (DBDE) and quadratic discriminant analysis (QDA). For attack detection, the speedy ensemble classifier is used, which combines Holte's 1R, random tree, and reduced error pruning tree. In the experiments, the NSL-KDD, UNSW-NB15, and CICDDoS2019 datasets are used. According to the experimental results, the proposed IDS reaches 95%-97.4%, 82.7%, and 99.5%-99.9% detection rates for the NSL-KDD, UNSW-NB15, and CICDDoS2019 datasets. In this way, the proposed IDS competes with the state-of-the-art methods in terms of detection rate and false alarm rate. In addition, the proposed IDS has a lower computational cost than the state-of-the-art methods. Moreover, DBDE-QDA reduces the dimension by 60.97%-82.92%, 73.46%, and 96.55%-98.85% for the NSL-KDD, UNSW-NB15, and CICDoS2019 datasets.

(Marmara Univ, Fac Medicine, 2025) Donmez, Muhammet Oguzhan; Sener, Goksel; Akbay, Tugba Tunali; Sivas, Guzin Goksun; Akakin, Dilek; Unlu, Hilal; Goren, Mehmet Zafer
Objective: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system characterised by demyelination. The aim of this study was to evaluate the neuroprotective effects of Korean ginseng root extract (KGE) using a cuprizone-induced demyelination model. Materials and Methods: C57BL/6 mice were divided into control, demyelination and remyelination groups and each group was treated with KGE. Demyelination was induced with 0.2% cuprizone in the diet for four weeks. KGE (100 mg/kg) was administered by gavage during or after the cuprizone exposure. Body weight, food and water intake, and motor performance parameters were investigated. In addition, glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD) malondialdehyde (MDA), oligodendrocyte transcription factor-2 (OLIG2) and myelin basic protein (MBP) levels were measured in brain samples, while MBP and glial fibrillary acidic protein (GFAP) expression was assessed by immunohistochemistry and myelin status was examined using Luxol Fast Blue staining. Results: Korean ginseng root extract prevented myelin loss, promoted remyelination, and improved motor performance. It reduced oxidative stress by increasing GSH, GST, and SOD levels while decreasing MDA. KGE also suppressed demyelination by reducing astrogliosis and restoring OLIG2 and MBP levels. Conclusion: Korean ginseng root extract exhibits neuroprotective properties during demyelination and promotes remyelination, highlighting its therapeutic potential for MS.

Irrational Beliefs and Moral Behaviors: Are Irrational Performance Beliefs Predictor of Prosocial and Antisocial Behaviors in Athletes?
(Springer, 2024) Urfa, Osman; Asci, F. Hulya
The aim of this study was to investigate the atemporal mediating role of secondary irrational beliefs in the relationship between primary irrational beliefs and prosocial-antisocial behaviors in athletes. Ninety-two males (Mage=19.83 +/- 2.80) and 32 females (Mage=19.28 +/- 1.44), a total of 124 athletes (Mage=19.69 +/- 2.52) voluntarily participated in this study. Irrational Performance Belief Inventory-2 and Prosocial and Antisocial Behavior Scale were administered, and regression analysis was performed by using bootstrapping via PROCESS macro v4.2. Analysis indicated a significant atemporal direct effect of awfulizing belief on prosocial behaviors toward teammates and opponents. The direct effect of low frustration tolerance belief on prosocial behaviors toward opponents was also significant. Demandingness, awfulizing, and depreciation beliefs had atemporal direct effects on antisocial behaviors toward teammates. There were significant atemporal indirect effects of demandingness belief on prosocial behaviors toward teammates through awfulizing, prosocial behaviors toward opponents through low frustration tolerance, and antisocial behaviors toward teammates through low frustration tolerance and depreciation. In conclusion, there is atemporal mediating role of secondary irrational performance beliefs in the relationship between primary irrational performance beliefs and prosocial-antisocial behaviors.
