Effects of ıntermittent versus continuous small-sided games on athletic performance in male youth soccer players: a pilot study
No full textAdjusting the design of small-sided games and selecting the appropriate format can significantly enhance training outcomes and player development in soccer. The aim of the study was to compare the effects of intermittent small-sided games (ISSG) and continuous small-sided games (CSSG) on athletic performance metrics in male soccer players. This pilot study was conducted using a parallel group pre-test and post-test design, with 16 male youth soccer players randomly assigned to two groups: the ISSG group (n = 8, Mean age = 16.50 ± 0.53 years) and the CSSG group (n = 8, Mean age = 16.63 ± 0.52 years), ensuring a balance in pre-test performance and playing positions. The ISSG protocol began with 4 min sets in week one, progressively increasing to 7 min by week four, with 2 min rest intervals. The CSSG protocol involved continuous play, starting at 16 min and progressing to 28 min over the same period. Players underwent pre- and post-tests, with a 4-week training period. Performance metrics assessed included body composition, a 30 m sprint test, agility, horizontal jump, aerobic and anaerobic capacity, and static balance. Training intensity was monitored using the CR-10 Borg Rating of Perceived Exertion scale throughout the training period. Both groups exhibited improvements in horizontal jump, agility, aerobic and anaerobic power, and static balance, with no significant between-group differences. Sprint performance did not significantly improve in either group. The CSSG group reported higher RPE values and experienced a reduction in body mass index. Our findings demonstrate that both ISSG and CSSG resulted in similar improvements in athletic performance metrics in male youth soccer players. Coaches and practitioners can choose the most appropriate training method based on specific objectives, session duration, and player fatigue levels, thereby optimizing training outcomes. © 2025 by the authors
Childhood cancer survivorship care in limited resource settings: a narrative review and strategies to promote global health equity
No full textThe WHO Global Initiative for Childhood Cancer, prompted by the marked inequity of survival across the globe, aims to increase survival rates in low- and middle-income countries to 60% by 2030. In tandem with this effort, implementing survivorship-focused care is crucial to mitigate late effects and prevent early mortality beyond the 5-year survival end point. The observed burden of secondary malignancies, cardiovascular disease, and other chronic health conditions in adult survivors of childhood cancer in high-income countries provides guidance to generate evidence in limited-resource settings. The implementation of risk stratification tools, population health management, and development of contextually relevant health care delivery models, within the current landscape of survivorship care in Latin America, Africa, and Asia as examples, are vital to continue the momentum to ensure equitable care and quality of life for all survivors of childhood cancer. This narrative review informed by expert opinion serves as a call to action for survivors, advocacy groups, health professionals, health systems, governments, and global organizations to look beyond the 5-year survival benchmark
Effect of solution-blown polyamide-6 nanofiber interlayer on drilling performance of carbon fiber reinforced composites
No full textThis study examines the effect of solution-blown polyamide-6 (PA6) nanofiber interlayers on the drilling performance of carbon fiber reinforced polymer (CFRP) composites. Results demonstrate that PA6 nanofiber interlayers significantly reduce drilling thrust force and improve surface quality. Specifically, at a spindle speed of 1000 r/min and a feed rate of 1500 mm/min, the maximum thrust force was reduced by 17%, from 683.33 N in neat composites to 583.13 N in nanofiber-reinforced composites. At a higher spindle speed of 8000 r/min and a feed rate of 500 mm/min, thrust force decreased by 18%, from 80.22 N to 65.46 N. Surface roughness analysis revealed that nanofiber interlayers reduced Ra values by up to 44%, with a minimum roughness of 0.529 mu m compared to 1.196 mu m in neat composites. Optical and SEM analyses confirmed fewer plucking zones, reduced fiber pull-out, and improved fiber-matrix bonding in nanofiber-reinforced samples, particularly at higher spindle speeds. These findings indicate that PA6 nanofiber interlayers enhance drilling performance, offering reduced machining forces and superior hole quality for precision applications in the aerospace and automotive industries
Validity and reliability of the turkish version of the ottawa sitting scale in patients with multiple sclerosis
Full text linkPurpose This study aimed to examine the validity and reliability of the Turkish version of the Ottawa Sitting Scale (OSS-TR) in patients with multiple sclerosis (MS). Methods The study included 52 patients aged 29-45 who were diagnosed with MS based on McDonald criteria. To establish construct validity, structural (with confirmatory factor analysis, CFA) and convergent validity were examined. For convergent validity, the associations between the OSS-TR score with the Trunk Impairment Scale (TIS) and Berg Balance Scale (BBS) scores were analyzed. The average variance extracted (AVE) and construct reliability (CR) were calculated to enhance the assessment of convergent validity. To assess the reliability of the OSS-TR, the scale was re-administered to all participants seven days later by the same rater, and the intraclass correlation coefficient (ICC) was computed to determine the test-retest reliability. Results According to the factor analysis results, the scale was found to have a single factor. CFA indicated that the model fit indices for the OSS-TR were acceptable, verifying its construct validity. Strong correlations between the OSS-TR score and BBS (r = 0.843) and TIS (r = 0.867) scores confirmed the convergent validity of the OSS-TR (p < 0.05). Furthermore, the fact that the AVE score (0.578) was greater than 0.50 and the CR score (0.905) was greater than 0.70 supported convergent validity. The OSS-TR had high test-retest reliability (ICC = 0.953) and internal consistency (Cronbach's alpha = 0.934). Conclusion According to the results of the study, the OSS-TR is a reliable and valid tool for assessing sitting balance in Turkish-speaking MS patients
Fault diagnosis in thermal images of transformer and asynchronous motor through semantic segmentation and different CNN models
No full textTransformers are crucial power equipment that play an important role in changing voltage levels to meet consumer needs and in transmitting electricity. A fault in a transformer can cause significant economic losses and social problems. Similarly, asynchronous motors are widely used in industry, and faults in these motors can have substantial negative effects on both the economy and human life. Early detection of faults in both types of power equipment can save time and costs, as well as allow for remedial measures to prevent the failure of the entire system. Traditional fault diagnosis methods, which integrate various monitoring and measurement equipment into power systems, are not sufficient for early fault detection. Therefore, modern solutions have evolved towards more reliable and risk-free artificial intelligence (AI)-based automatic fault diagnosis methods. In our application, we aim to determine faults based on AI in thermal images of asynchronous motors and transformers in operation. Specifically, we propose a semantic segmentation application that highlights fault areas on thermal images, setting other pixels as background. This approach allows the region where the fault occurred to be taken as a reference for later fault diagnosis. As a result of semantic segmentation, the winding of the transformer and the stator region of the asynchronous motor are automatically segmented. Data augmentation techniques are then applied to these segmented images. Augmented and segmented motor and transformer images are classified using seven different Convolutional Neural Network (CNN) models. The results show that CNN models provide fault classification with accuracy reaching 100% for transformers and 96.49% for asynchronous motors

Investigation of the effects of wafer-baking plates on thermal distribution, wafer thickness, and wafer color distribution
Full text linkFeatured Application The thermal distribution of two baking plates with different materials (GG-25 gray cast iron and GJV-350 vermicular cast iron), their effects on the thickness of the wafer sheet, and their effects on the color distribution of the wafer sheet were investigated at different baking rates. The GJV-350 vermicular casting plate provides a more homogeneous heat distribution, more stable wafer sheet thickness, and more homogeneous color distribution of the wafer sheet at a maximum production rate.Abstract Wafer-baking ovens are machines that bake liquid batter by heating the interconnected cast plates in a gas oven. The plates in contact with the wafer batter are generally made of the cast material. Although there are many studies on the contents in the recipes of wafer products and the effects of the additives included in the recipes on the quality of the wafer sheet, there are few studies on the effects of the material type of the wafer-baking plate on the baking process. In this study, the thermal distribution of two baking plates made of different materials (GG-25 gray cast iron and GJV-350 vermicular cast iron), their effects on the thickness of the wafer sheet, and their effects on the color distribution of the wafer sheet were investigated at different baking rates. The experiments were conducted in an industrial wafer-baking oven at two different production rates. As a result, it was observed that the GJV-350 vermicular casting plate provides a more homogeneous heat distribution, more stable wafer sheet thickness, and more homogeneous color distribution of the wafer sheet at a maximum production rate.Karaman city-KOSGEB Institution [205719]This study was supported by Karaman city-KOSGEB Institution (Project No: 205719).

Kinesio Taping does not Enhance Jump Performance and Muscle Activity in Female Athletes
No full textThis study aimed to investigate the effect of Kinesio Taping (KT) application on the single-leg counter-movement jump (CMJ) and surface electromyographic (sEMG) activity in trained female athletes, in both resting and fatigued states. In this single-blind, randomized, sham-controlled trial, twenty-four healthy trained female athletes were randomly assigned to either the KT (n=12) or the sham tape group (n=12). KT was applied using an inhibition technique on rectus femoris, vastus medialis, biceps femoris, and lateral gastrocnemius muscles of the dominant leg. A single-leg CMJ test and sEMG activity were recorded at baseline (no tape), as well as at 1 hour, 24 hours, and 48 hours after taping. To induce acute neuromuscular fatigue, a 30-second repetitive CMJ test was used to evaluate KT in fatigued states. In the resting states, both groups exhibited improvements in jump height, power, mean velocity, and sEMG activity (%EMGmax) over time, with no significant between-group differences. The single-leg CMJ performance was similarly decreased after the muscle fatigue protocol in both groups, showing no between-group differences. Our findings suggest that KT treatment does not appear to influence jumping performance, sEMG activity, or muscle fatigue in female athletes

Smart cities from a critical perspective: an awareness research on metropolitan municipalities
Full text link2008 mali krizinin ardından kentlerin ekonomik ve ekolojik krizine teknoloji marifetiyle çare üreteceği varsayılan akıllı kent konusu, günümüzde akıllı kentin iktisadi ve sosyal maliyetlerinin dikkate alındığı bir bağlam içinde değil; aksine maliyet azaltıcı teknolojik avantajların tek yanlı ve abartılı biçimde ön plana çıkarıldığı bir çerçevede tartışılmaktadır. Bu çalışmada ise akıllı kentin, tarafsız-nesnel bir kent politikası olamadığı, teknoloji üreticileri ve teknolojik yatırımları yoluyla marka değeri edinmek isteyen yönetimler tarafından desteklendiği; akıllı kent teknolojilerinin sürdürülebilirliği otomatik biçimde destekleme yeterliliği bulunmadığı; dijital bölünme başta olmak üzere çeşitli rizikolar ürettiği ileri sürülmektedir. Bu bağlamda, ülkemizdeki kent yönetimlerinin akıllı kente yaklaşımlarını değerlendirebilmek amacıyla, 30 büyük şehir belediyesinin web siteleri, portalları, strateji planları incelenmiştir. Yapılan taramayla büyükşehir belediyelerinin akıllı kentin muhtemel riskleri ile ilgili farkındalıkları incelenmiş ve netice olarak 2 büyük kent (İstanbul ve Konya) dışında belirgin bir farkındalığa sahip olunmadığı bulgulanmıştır.The smart city issue, which is assumed to provide a solution to the economic and ecological crisis of cities through technology after the 2008 financial crisis, is not in a context where the economic and social costs of the smart city are taken into consideration today; On the contrary, it is discussed in a framework where cost-cutting technological advantages are highlighted in a one-sided and exaggerated manner. In this study, it is stated that smart city cannot be a neutral-objective city policy and is supported by technology producers and governments that want to gain brand value through technological investments; smart city technologies are not capable of automatically supporting sustainability; It is claimed that it creates various risks, especially the digital divide. In this context, the websites, portals and strategy plans of 30 metropolitan municipalities were examined in order to evaluate the approaches of city administrations in our country to the smart city. With the screening, the awareness of metropolitan municipalities about the possible risks of the smart city was examined and as a result, it has been found that there is no significant awareness except for 2 big cities (Istanbul and Konya)
