Article Citation - WoS: 7Citation - Scopus: 8Evaluating Space Efficiency of Tall Buildings in Turkey(Mdpi, 2024) Aslantamer, Ozlem Nur; Ilgin, Huseyin EmreIn response to the increasing building demands in Turkey, particularly in the metropolitan area of Istanbul, followed by other major cities such as Ankara and Izmir, the expansion of construction zones has led to the emergence of tall towers as a pragmatic solution. The design and implementation of tall buildings require newer technologies and interdisciplinary collaboration in aspects such as facade installation, vertical circulation solutions, and fire systems, compared to low-rise buildings. In spite of the proliferation of skyscrapers, there is a noticeable lack of thorough study on space efficiency in Turkey's tall buildings. This article aims to fill this significant gap in the literature. The research method employed in this study focuses on a case study of 54 modern towers constructed in Turkey between 2010 and 2023, ranging in height from 147 to 284 m. Key findings are as follows: (1) residential use, central core, and prismatic forms are the most prevalent architectural preferences; (2) the most preferred structural material and system are concrete and the shear-walled frame system, respectively; (3) average space efficiency and the percentage of core-to-gross-floor area (GFA) were 78% and 19%, respectively, with measurement ranges varying from a minimum of 64% and 9% to a maximum of 86% and 34%. This paper will provide insight for construction stakeholders, especially architects, for sound planning decisions in the development of Turkish tall buildings.Article Citation - WoS: 5Citation - Scopus: 5Factors Associated With Kinesiophobia in Patients With Knee Osteoarthritis(Georg Thieme Verlag, 2022) Acar,M.; Sönmezer,E.; Yosmaoǧlu,H.B.Purpose This study aims to determine factors affecting kinesiophobia in patients with knee osteoarthritis (OA). Materials and Methods The fear of movement was measured using the Tampa Scale of Kinesiophobia in 60 patients with knee OA. Pain intensity was assessed with the Visual Analog Scale, quality of life with the Nottingham Health Profile (NHP), disability with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), anxiety and depression with the Hospital Anxiety and Depression Scale (HADS), balance with the Berg Balance Scale, mobility with the Timed Up and Go Test, and the physical activity status was measured with the International Physical Activity Questionnaire. Results Physical mobility and emotional reactions subscales of NHP, all WOMAC subscales and the HADS depression subscale were significantly related to kinesiophobia. Muscle strength, ROM, level of physical activity, balance, mobility and anxiety were not significantly related to kinesiophobia. Quality of life and disability explained 34.4% of the variation in the Tampa Scale of Kinesiophobia. Conclusions Kinesiophobia was associated with quality of life, disability and depression. It may be useful for clinicians to pay attention to the evaluation of psychosocial characteristics instead of physical performance parameters in order to increase treatment success in OA patients. © 2022 GeorgThieme.

The patients were prescribed the combination of hydrolyzed type 2 collagen, MSM, GS, and CS as a supplement for knee OA. The sachet form of the combined supplement containing 1250 mg hydrolyzed type 2 collagen, 750 mg MSM, 750 mg GS, and 400 mg CS was used once daily for two consecutive months. Patients were evaluated according to the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analog Scale (VAS)-pain, and Health Assessment Questionnaire (HAQ). Patients were scheduled to visit for follow-up four weeks (Visit 2) and eight weeks (Visit 3) after Visit 1 (baseline; day 0 of the study).Results: For the VAS-pain, WOMAC, WOMAC-subscale, and HAQ scores, the differences in improvement between the three visits were significant (p<0.001 for all). The patient compliance with the supplement was a median of 96.77%, both for Visit 2 and Visit 3. Conclusion: The combination of hydrolyzed type 2 collagen, MSM, GS, and CS for eight weeks in knee OA was considered an effective and safe nutritional supplement.Article Citation - WoS: 4Citation - Scopus: 3The Effect of Combined Hydrolyzed Type 2 Collagen, Methylsulfonylmethane, Glucosamine Sulfate and Chondroitin Sulfate Supplementation on Knee Osteoarthritis Symptoms(Baycinar Medical Publ-baycinar Tibbi Yayincilik, 2024) Ayhan, Fikriye Figen; Çoban, Ayşegül Demirci; Karasu, Ayça Utkan; Karaoğlan, Belgin; Çınar, Ece; Eyigör, Sibel; Dalyan, MeltemObjectives: This study aimed to evaluate the effects of the combined hydrolyzed type 2 collagen, methylsulfonylmethane (MSM), glucosamine sulfate (GS), and chondroitin sulfate (CS) supplement on knee pain intensity in patients with knee osteoarthritis (OA).

The city-state's innovative and adaptive approach has enabled it to overcome the challenges associated with skyscraper construction, leading to the development of some of the most advanced and sustainable high-rise structures in the world. However, there is currently a lack of detailed analysis on space utilization in Singaporean high-rise buildings. This study addresses this gap by examining 63 cases. The main findings of this research: 1. Residential functions, central core layouts, and prismatic shapes are the most frequent. 2. Concrete material with a shear-walled frame system is the preferred structural choice. 3. Average spatial efficiency is 80%, and the core-to-GFA (Gross Floor Area) ratio averages 17%. These metrics vary from a minimum of 68% and 5% to a maximum of 91% and 32%, respectively. These insights offer valuable guidance for Singaporean construction professionals, particularly architects, helping them make informed design decisions for high-rise projects.
