İstanbul’da Bulunan Ahşap Evlerin Kullanıcı Memnuniyeti Açısından Değerlendirilmesi
Get PDFAhşap evler, geleneksel Türk mimarisinde önemli yere sahip yapılardır. Geçmiş dönemde Anadolu’da yapılan evlerin çoğunluğunun ahşap olduğu görülmektedir. Ahşap doğal, sıcak, geri dönüştürebilir, tasarım esnekliği olan ve ülkemizde kaynağı kolay bulunabilen bir malzemedir. Bir yüzyıl öncesine kadar Anadolu’da yaygın olarak kullanılan ahşap yapıların kullanımı günümüze ulaşan süreç içerisinde oldukça azalmıştır. Türkiye’nin deprem bölgesi üzerinde yer alması ve ülkemizde son yıllarda yaşanan depremler nedeniyle ahşap evlere olan ilgi artmış, ahşap evlerde yaşamak isteyen kullanıcı sayısı çoğalmıştır. Özellikle 1999 Marmara depreminden sonra oluşan bu ilgi artışı dikkat çekicidir. Ancak günümüze ulaşan süreçte bu ilginin süreklilik göstermediği düşünülmektedir. Türk yapı sektöründe ahşap yapım sistemleri betonarme sistemler kadar yaygın kullanılmamaktadır. Deprem bölgesi olan ülkemizde betonarme sistemle oluşturulan yapılar yerine ahşap ve çelik sistemler gibi depreme karşı daha güçlü dayanım gösterebilen sistemlerin kullanımının artırılmasının gerekliliği açıktır. Ahşap yapılara, ahşap malzemenin getirdiği birtakım olumsuzluklar nedeniyle kullanıcı açısından ön yargı ile yaklaşıldığı düşünülmektedir. Bu çalışma kapsamında İstanbul’da 1999 Marmara depremi sonrasında inşa edilen ahşap yapılarda ikamet eden kullanıcıların, olumlu ve olumsuz yargılarının tespit edilmesi amaçlanmıştır. Çalışmanın yazarı tarafından özgün olarak hazırlanan bir anket formu, ahşap ev kullanıcılarına yüz yüze olarak uygulanmıştır. Çalışmaya 62 ahşap ev kullanıcısı katılmıştır. Çalışma sonucunda ahşap ev kullanıcılarının ahşap evlerde yaşamaktan mutlu oldukları ve bu evlerde yaşamaya devam etmeyi düşündükleri görülmüştür. Depreme dayanım açısından güçlü olan ve zayıf zeminler üzerine kolaylıkla inşa edilebilen ahşap yapım sistemlerinin yaygınlaştırılması ve kullanım alanının artırılmasına yönelik dikkat çekilmesi, çalışmanın ülkemiz yapı sektörüne vereceği katkı olarak düşünülmektedir

The three-factor structure accounted for 70.40% of the total variance. The items' standardised factor loads were between 0.501 and 1.140. The Cronbach's alpha consistency value was 0.90.ConclusionThe staff version of the questionnaire is an adequately valid and reliable instrument in the Turkish language
Virginia Woolf’un “Street Haunting: A London Adventure” Denemesinde Şehirde Dolaşmanın Kadın Biçimi
Get PDFBu makale, Virginia Woolf’un 1927 tarihli “Street Haunting: A London Adventure” başlıklı denemesini ve buradaki aylak kent gezginliğinin (flânerie) kadına özgü tasvirini ele almaktadır. Makalenin başında edebiyat çalışmalarında mekânın önemi ve güncel akademik incelemelerde gözlemlenen ve “mekânsal dönüş” adı verilen değişim kaydedilmektedir. Ardından, şehirlerin modernist edebiyattaki rolüne, özellikle de bu akıma mensup metinlerdeki yer ve zamanları, anlatı özelliklerini ve temaları şekillendirmedeki etkisine değinilmektedir. Ayrıca, Henri Lefebvre ve Yi-Fu Tuan gibi “mekânsal dönüş”ün öncüleri arasında yer alan isimlerin temel fikirlerine genel bir bakış sunulmaktadır. Çalışmada Woolf’un denemesinin aylak kent gezginliği üzerine benzersiz bir yaklaşım sergilediği, yazarın şehir sokaklarında bir içe bakış ve duygusal derinlik hissiyle dolaştığı öne sürülmektedir. Woolf’un şehir manzarasına dair gözlemleri ve şehirdeki yabancılarla karşılaşmaları, günlük yaşamın olanca karmaşıklığını yansıtan zengin bir potansiyel anlatı dokusu yaratmasına olanak tanımaktadır. Bu çalışmada ayrıca Michel de Certeau’nun yürümeyi bir tür taktiksel-retorik direniş ve anlam yaratma edimi olarak ortaya koyduğu kuramı tartışılmakta ve de Certeau’nun fikirlerinin Woolf’un denemesiyle ilişkisi öne çıkarılmaktadır. Woolf’un aylak kent gezginliği, erkek “flanör” figüründen farklı olarak yalnızca şehir kalabalığının ve çevrenin mesafeli biçimde gözlemlenmesiyle ilgili değildir, aynı zamanda yazarlığa dair bir yön de barındırmaktadır zira Woolf, şehirde dolanırken yaşadığı duyguları ve deneyimleri yazdıklarına yansıtmaktadır. Bu incelemede esas olarak Woolf’un kadın aylak kent gezgini (flanöz) tasvirinin geleneksel kamusal alan anlayışlarına meydan okuduğu, kadınların deneyimlerinin kentsel çevreyi ve bu çevrenin temsillerini yeniden tanımladığı vurgulanmaktadır
Evaluating and Comparing Student Responses in Examinations from the Perspectives of Human and Artificial Intelligence (GPT-4 and Gemini)
No full textBackgroundGenerative Artificial Intelligence (AI) models, such as ChatGPT (GPT-4) and Gemini, offer potential benefits in educational settings, including dental education. These tools have shown promise in enhancing learning and assessment processes, particularly in dental prosthetic technology (DPT) and oral health (OH) programs.ObjectiveThis study aimed to evaluate the accuracy, reliability, and consistency of GPT-4 and Gemini AI models in answering examination questions in dental education. The study focused on multiple-choice questions (MCQs), true/false (T/F) questions, and short-answer questions (SAQs).MethodsAn exploratory study design was used with 30 questions (10 MCQs, 10 T/F, and 10 SAQs) covering key topics in DPT and OH education. ChatGPT and Gemini were tested with the same set of questions on two separate occasions to assess consistency. Responses were evaluated by two independent researchers using a predefined answer key. Data were analyzed using descriptive statistics, the Kappa coefficient for agreement, and the Chi-square test for categorical variables.ResultsChatGPT demonstrated high accuracy in MCQs (90%) and T/F questions (85%) but showed reduced performance in SAQs (60%). Gemini's accuracy ranged between 60% and 70%, with the highest accuracy in SAQs (70%). ChatGPT showed significant consistency across testing dates (Kappa = 0.754; p = 0.001), whereas Gemini's responses were less consistent (Kappa = 0.634; p = 0.001).ConclusionWhile both AI models offer valuable support in dental education, ChatGPT exhibited greater accuracy and consistency in structured assessments. The findings suggest that AI tools can enhance teaching and assessment methods if integrated thoughtfully, supporting personalized learning while maintaining academic integrity

Investigation of the Printability of Ethyl 2-[4 on Coated and Uncoated Papers]
No full textThere is a growing demand in the printing industry for pigment-based inks with excellent lightfastness and rub resistance qualities. In this work, a novel ink with the formulation ethyl 2-[4-(1,3,4-oxadiazole-2(3H)-thione-5-yl)phenylhydrazono]-3-oxobutyrate (OXKT) was prepared as a pigment and its printability was investigated for use in printing. The OXKT was synthesised, characterised then printed on uncoated and gloss-coated papers and Bristol cardboard. Physical tests and spectrophotometric measurements were carried out to determine the technical characteristics of the printed ink. Additionally, print quality, ink density and gloss were evaluated. The results showed that the proposed ink with the OXKT compound had acceptable rub resistance. Also, the gloss and light fastness values exceeded the acceptable rates for the printing industry because of their colour differences. However, more research needs to be conducted to improve light performance. Nevertheless, it is still possible for use in applications that do not stipulate strict light fastness values.Turkiye Bilimsel ve Teknolojik Arastirma KurumuTurkiye Bilimsel ve Teknolojik Arastirma KurumuScience Citation Index Expande
The Effects of Diaphragmatic Breathing Exercises on Individuals with Premature Ejaculation: A Randomized Controlled Trial
No full textBackground There are no standardized, evidence-based rehabilitation protocols for premature ejaculation (PE) which hinders effective management, the development of validated patient-reported outcomes, regulatory oversight, and the potential benefits of targeted interventions. Aim To investigate the effect of diaphragmatic breathing exercises (DBE) on PE. Methods Sixty-two participants with PE were randomly assigned to Group I (n = 31) or Group II (n = 31). Both groups received behavioral therapy (BT) and pelvic floor muscle training (PFMT) twice daily, three days a week, for eight weeks. Additionally, Group I recieved DBE twice daily, every day, for eight weeks. Intravaginal ejaculation latency time (IELT) was calculated with a stopwatch, at the end of the 8th week (post-treatment), and at 1-year follow-up. Pelvic floor muscle (PFM) strength and endurance were evaluated with ultrasound, and changes in the in the autonomic nerves system (ANS) parameters (including the root mean square of successive differences [RMSSD], proportion of NN50 [PNN50], low-frequency [LF] power, and high-frequency [HF] power) were evaluated with an Elite HRV device at pre-treatment and post-treatment by a blinded assessor. Outcomes Primary outcome measurements were IELT, PFM strength and endurance, and changes in ANS paramaters. Results The study was completed by 29 participants (mean age = 31.4 ± 6.5 years) in Group I and 30 (mean age = 31.3 ± 7.6 years) in Group II. At post-treatment, all outcome measures showed significant improvements in both groups (P <.001 for all). Compared to Gropu II, Group I showed significantly greater improvements in IELT(P=0.12), RMSDD (P<.001), PNN50 (P=.003), LF Power (P<.001), HF Power (P=.003), strength(P<.001), and endurance (P<.001). The median IELT increase from baseline to post-treatment was 283 seconds (range: 84-870; 900%) in Group I and 204 seconds (range: 44- 581; 690%) in Group II. While IELT declined significantly from post-treatment to 1-year follow-up in Group II, no statistically significant change was found in Group I. Clinical Implications The effect of DBE on the ANS may help regulate the ejaculatory reflex. Strengths and Limitations This is the first study to apply breathing exercises with BT and PFMT in men with PE. Limitations include the lack of exercise adherence records beyond 8 weeks and the estimation-based IELT measurement at baseline. Conclusion Adding DBE, to BT and PFMT, yields better results in IELT (at 8 weeks and 1 year) and inreases PFM strength and endurance of PFM (at 8 weeks) in men with PE. © 2025 Elsevier B.V., All rights reserved.Science Citation Index Expande
Empowering a Mother of Children With Autism: a Case Report on the Impact of Tele-Occupational Performance Coaching on Parent-Child Relationships, Maternal Self-Efficacy, and Occupational Performance
No full textAydoner Bektas, Selen/0000-0002-0663-1802This case report aimed at tele-occupational performance coaching to empower the mother of a child with autism spectrum disorder by enhancing occupational performance, parent-child relationships, and maternal self-efficacy. Over 8 weeks, the intervention addressed goals collaboratively identified by the mother, including self-care, productivity, and leisure-related tasks. Results revealed clinically significant improvements, with a two-point increase in Canadian Occupational Performance Measure scores for both performance and satisfaction. Significant score increases were also obtained on the Parent-Child Relationship Scale and the Early Intervention Parenting Self-Efficacy Scale. The findings underscore the effectiveness of tele-occupational performance coaching in enhancing family dynamics and parental capabilities while emphasizing the potential of telehealth as a scalable and accessible modality for delivering family-centered occupational therapy. Future research should expand on these findings by incorporating diverse populations and assessing long-term outcomes.Emerging Sources Citation Inde
Synthesis, Molecular Modeling, Anti-Cancer and COX-1/2 Inhibitory Activities of Novel Thiazolidinones Containing Benzothiazole Core
No full textIn this study, new 1,3-thiazolidin-4-one derivatives containing arylmethylene groups in the 5-position were obtained from 6-(trifluoromethoxy)-1,3-benzo-thiazol-2-amine (riluzole). Synthesized compounds were characterized by spectral data and elemental analysis. In vitro, cytotoxic activities of the synthesized molecules were evaluated against the human lung cancer (A549) and human prostate cancer (PC-3) cell lines. Compounds were also tested on mouse embryonic fibroblast cells (NIH/3T3) to determine selectivity. Ten target compounds 3-12 were also screened for their COX-1 and COX-2 inhibitory activities. Of these compounds, 4 showed the highest COX-2 inhibition at 10 mu M. Molecular docking calculations were performed to understand the binding interactions of compounds with COX-1 and COX-2 proteins. In silico studies of the tested compounds represented important binding modes that may be responsible for their anti-cancer activity via selective inhibition of the COX-2 enzyme. ADMET predictions were conducted to assess the drug-like properties of the novel compounds.Science Citation Index Expande
Safety and Efficacy of Umbilical Cord Mesenchymal Stem Cells in the Treatment of Type 1 and Type 2 Diabetes Mellitus: a Systematic Review and Meta-Analysis
No full textIbrahim, Ismail; Oteri, Vittorio; Hafez, Wael; Shalabi, LailaIntroduction Many patients struggle to control glucose without side effects. Due to their immunomodulatory and regenerative properties, mesenchymal stem cells (MSCs) might treat Diabetes Mellitus (DM). The authors employed this meta-analysis to evaluate the efficacy and safety of umbilical cord MSCs (UCMSCs) for DM management. Methods The PubMed, Cochrane, WOS, Embase, and Scopus databases were searched for randomized controlled trials (RCTs) investigating the effects of UCMSCs on DM (Types 1, 2) till January 2024. Patient demographics, interventions, and outcomes, including glycated hemoglobin (HbA1c%), C-peptide levels, and insulin requirements, were extracted. A comprehensive meta-analysis software was used. Results Eight CTs of 334 patients (172 experimental and 162 controls) were included. UMSCs treatment substantially lowered HbA1c levels (MD = -1.06, 95% CI [-1.27, -0.85], p < 0.00001) with consistent outcomes (i(2) = 0%, p = 0.43). Fasting C-peptide levels were heterogeneous but favored placebo (MD = 0.35, 95% CI [0.15, 0.56], p = 0.0007). In T1D patients, daily insulin requirements decreased considerably (MD = -0.24, 95% CI [-0.29, -0.18], p < 0.00001), with heterogeneity addressed by sensitivity analysis. Conclusion UMSCs therapy reduced HbA1c and insulin requirements, and increased C-peptide levels. Multicenter clinical trials are required to confirm the long-term efficacy and safety of UMSC therapy.Global Alliance of Young ResearchersThe authors thank the Global Alliance of Young Researchers for their support and high-quality mentorship.Emerging Sources Citation Inde
