This work develops a software interface that recognises food products using deep learning algorithms, and announces their nutritional values and gastronomic characteristics. Specifically, photographs of various desserts were captured in a restaurant setting, and the classification performance of two deep learning models, GoogleNet and ResNet-50, was analysed. Both models achieved high accuracy rates exceeding 99.6 %, with ResNet-50 demonstrating superior performance due to its lower error rates, higher accuracy, and faster learning capabilities. Based on these results, the interface was developed using ResNet-50 to provide consumers with detailed gastronomic information about desserts and support healthier dessert choices. At present, the resulting software is limited to the 23 dessert items on the menu of Healin restaurant (Nisantasi, Istanbul, Turkey), and the way they look in that particular restaurant, but the scope could be expanded in the future. This innovative approach enhances consumer awareness about healthy eating while offering a competitive edge for the food industry by effectively meeting consumer expectations.Öğe Investigation of the relationship between well-being, body awareness and depression parameters in healthy adults(Inonu University, 2025) Safran, Ertuğrul; Zeylek, Beyzanur; Gültekin, Hasan Can; Usluer, İrem Nur; Otsay, SelvaIn this study, the relationship between well-being, body awareness and depression in healthy adults has been examined.

Recent Findings: The hormone calcitriol plays a vital role in regulating a multitude of biological processes within the human body. Its deficiency can lead to significant adverse effects on overall health and well-being, including physical and psychological consequences. Evidence indicates that vitamin D may exert influences through receptors in the brain, modulating serotonin production and influencing emotional and cognitive processes. Recent studies propose that elevated serum vitamin D may enhance mood and alleviate depressive states. The impact of vitamin D on cognitive function and behavior remains an area of ongoing investigation. This literature review analyses the available evidence on how vitamin D intake impacts the severity of illness and medication requirements in diverse psychiatric disorders. A review of the literature suggests that there may be a correlation between vitamin D and serotonin, which could potentially contribute to more favorable outcomes in the context of illness. Vitamin D may increase the amount of serotonin in the synaptic gap, which is the intended use of selective serotonin reuptake inhibitors (SSRIs), with its effect on the increase in serotonin release. Summary: According to reports, vitamin D supplementation in conjunction with SSRI group medication provides an additive effect for the management of psychiatric disorders.Öğe The effect of internet addiction on surgical nurses' malpractice tendencies: Turkish sample(Springer Nature, 2025) Gezginci Akpınar, Elif; Orhan, Büşra Nur; Göktaş, SonayBackground This study aimed to determine the effect of surgical nurses' internet addiction on their malpractice tendencies. Methods The descriptive cross-sectional study included 1051 nurses working in the surgical awards of 10 hospitals in Istanbul. Data were collected using a descriptive characteristics form, the Internet Addiction Scale, and the Malpractice Tendency Scale. An increase in the score on the internet addiction scale indicates that internet addiction increases. In contrast, an increase in the score on the malpractice tendency scale indicates that malpractice tendency decreases. Data were analyzed using independent groups t-test, one-way ANOVA test, Pearson correlation and linear regression analyzes with IBM SPSS Statistics version 22.0 software. Results A weak negative correlation was found between the surgical nurses' total scores on the Internet Addiction Scale and Malpractice Tendency Scale (r=-0.422 p < 0.001). Internet addiction total score was also negatively correlated with malpractice tendency subscale scores for medication and transfusion administration safety (r=-0.450 p < 0.001); infection prevention (r=-0.416 p < 0.001); patient monitoring, device, and material safety (r=-0.321 p < 0.001); fall prevention (r=-0.325 p < 0.001), and communication (r=-0.332 p <= 0.001). In linear regression analysis, an increase in internet addiction overall and in the lack of control subscale was associated with greater malpractice tendency (ss=-0.422 and ss=-0.243, respectively). Internet addiction explained a total of 17.7% of the total change in malpractice tendency (R2 = 0.177). Conclusion Surgical nurses showed increased malpractice tendency as their internet addiction level increased. This relationship was seen in all domains of malpractice, including medication and transfusion administration safety, infection and fall prevention, communication, and patient monitoring, device, and material safety. It is recommended that in-service training be planned for conscious internet use to limit the time nurses spend on the internet during working hours.Öğe Structural and electrical properties of CuO-doped NaNbO3 ceramics(Walter de Gruyter GmbH, 2025) Berksoy Yavuz, Ayşe; Danışman, MuratCeramics are one of the key materials of today’s industry. The manufacturing technique used for preparing the ceramics greatly affects the material’s structural and electrical properties. Therefore, the elements and their distribution in the material as well as understanding their relation with the manufacturing process are the key factors for managing the expected outcome. In this study, NaNbO3 ceramics and the effect of CuO-doping in solid state calcination process was investigated. For this purpose pure, 0.5 mol.% and 1.0 mol.% CuO-doped sample discs were prepared. Crystallite size, strain, atomic structure, lattice parameters and atomic occupancies of the material were calculated by using X-ray diffraction patterns combined with Rietveld analysis. Additionally, the samples were investigated with the scanning electron microscopy technique to observe the effect of CuO doping. For electrical characterization, dielectric constant and tangent loss measurements were carried out on samples. As a result, it was concluded that CuO doping affected the crystal structure of the NaNbO3 which triggered the changes in its electrical behavior. The observed effects were more pronounced at 1.0 mol.% CuO content.Öğe The acute effects of motor imagery combined with action observation breathing exercise on cardiorespiratory responses, brain activity, and cognition: a randomized, controlled trial(Wiley-Hindawi, 2025) Atak, Ebrar; Ataç, AmineBreath and brain activity have been integral to daily life since time immemorial. Cognition and cardiorespiratory responses are closely interlinked, necessitating further investigation into their dynamics. The potential benefits of combining motor imagery (MI) and action observation (AO) based breathing exercises in rehabilitation have not been fully explored. This study was aimed at assessing the acute effects of MI combined with AO on cognitive function and cardiorespiratory responses. Thirty-three healthy adults were randomized into MI combined with AO breathing (MI+AO), active respiratory exercise (ARE), and control groups, with equal distribution across groups. Electroencephalography (EEG) data were collected using a Muse EEG headband, and cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) while imagining activities were measured via the Kinesthetic and Visual Imagery Questionnaire (KVIQ). Significant improvements in the Timed Up and Go (TUG) test and systolic blood pressure were observed in the ARE group (p < 0.05), alongside improvements in MoCA and KVIQ scores (p < 0.05). EEG data revealed significant decreases in delta and theta power at the temporoparietal (TP) location in the ARE group (p < 0.05). These findings suggest that MI and AO, when combined with respiratory exercises, may serve as effective passive strategies to support cognition and cardiorespiratory function, particularly in individuals who struggle to actively participate in pulmonary rehabilitation.Öğe Lactate kinetics and fatigue dynamics in elite taekwondo athletes during a 30-second continuous jump protocol(Projack, 2025) Kaya, Mehmet Zeki; Shahidi, Seyed HoutanBackground: This study examines lactate kinetics and performance declines during a 30- second BOSCO jump protocol in elite Taekwondo athletes, providing insights into anaerobic performance and recovery. Methods: Anthropometric data, including age, height, and weight, were collected, with averages of 21.2 years (+/- 2.0), 181.4 cm (+/- 4.8), and 70.6 kg (+/- 4.3). Fatigue-induced changes were assessed by measuring jump heights, contact times, and power outputs using the Witty Jump Mat (Italy) during the first and last 5 seconds of the protocol. Blood lactate concentrations were measured with the Lactate Scout 4 (Germany) at baseline, immediately postexercise, and at 3, 6, and 9 minutes post-exercise. Results: Significant declines were observed in jump height (mean decrease = 13%, p = 0.01) and power output (mean decrease = 15%, p = 0.02), alongside an increase in contact time (mean increase = 18%, p = 0.03), reflecting the impact of fatigue on explosive performance. Athlete B showed the greatest reduction in jump height (31.36%), revealing notable inter-individual variability in fatigue resilience. Blood lactate levels increased significantly from baseline (mean = 0.78 +/- 0.08 mmol/L) to peak post-exercise (mean = 3.16 +/- 1.19 mmol/L, p < 0.001) and subsequently declined. Lactate clearance rates were calculated as 40.5% at 3 minutes, 60.5% at 6 minutes, and 65.5% at 9 minutes post-exercise. Athlete D exhibited the fastest clearance rate (72%, p = 0.02), while Athlete C demonstrated delayed recovery. Conclusions: The findings underscore the need for tailored conditioning programs to optimize anaerobic performance and recovery in Taekwondo athletes. Future research should explore the effects of targeted training on anaerobic capacity and competition readiness in combat sports.Öğe Orta güçte bir kalıcı mıknatıslı senkron motorun performans karakteristiklerinin deneysel olarak elde edilmesi(Institute of Electrical and Electronics Engineers Inc., 2024) Demir, Onur; Erfan Kuyumcu, Feriha; Kep, YusufDünya çapında, kalıcı mıknatıslı senkron makinelere (KMSM) olan ilgi, uygulama alanlarının genişlemesiyle, bilhassa yenilenebilir enerji kullanımının artması ve ulaşımın elektrifikasyonu ile birlikte sürekli artmaktadır.

Research indicates that the quadriceps muscle group significantly influences jumping, balance, and ball-striking speed, while the hamstrings play a crucial role in maintaining knee stability during running and twisting movements. This study aims to evaluate the impact of isoinertial strength training, which is believed to enhance hamstring strength in young football players, on dynamic balance, dribbling skills, and shooting speed. Materials and Methods. Forty-two U-16 football players from amateur team academies participated in the study and were divided into an experimental group (EG, n = 21) and a control group (CG, n = 21). In this study, young football players in the EG engaged in a 15-min isoinertial strength training program, incorporated into their warm-up routine twice a week for 8 weeks, before standard football training sessions. In contrast, the CG adhered to their usual warm-up and football training practices during the study period. The research design involved pre-test assessments, a 6-week isoinertial training intervention, and post-test evaluations. Pre-test data were collected from all participants before the training period, and post-test data were collected upon completion of the program. Various performance measures were evaluated, including height, body weight, body mass index (BMI), the Y-balance test for dynamic balance, dribbling skills, and shooting speed. These assessments provided a thorough analysis of both physical and skill-related factors pertinent to football performance. The CG maintained their standard training regimen without the addition of isoinertial strength exercises, facilitating a comparison of the effects of the isoinertial training intervention on the selected outcomes. Results. The data presented in this study indicate the potential of eccentric training to significantly enhance shooting speed (p < 0.001), balance (p < 0.001), and skill performance (p < 0.004) in adolescent athletes (p < 0.001). Conclusions. Improving skill-related performance during adolescence is crucial for creating effective movement patterns early in athletic development, thereby preparing athletes for more complex movements in the future.Öğe A latitudinal evaluation between the learning styles and modes of the students in interior architecture education and the YKS score types(Istanbul Teknik Universitesi, Faculty of Architecture, 2024) Özsırkıntı Kasap, Handan; Türkmen, Anday; Aksoy Özler, Kübra; Tayilga, GamzeThe objective of this study is to investigate the relationship between the Higher Education Examination Score Types and Kolb Learning Styles of undergraduate students enrolled in the “Interior Architecture” and “Interior Architecture and Environmental Design” programmes, which accept students with diverse score types. In this context, a hypothesis was formed based on the difference between the score types and learning styles of students admitted to the Department of Interior Architecture with a numerical score type and students admitted to the Department of Interior Architecture and Environmental Design with an equal weight score type. A comparative relational survey model was selected to test the hypothesis. The study population consisted of foundation universities in Istanbul. In the 2021-2022 academic year, there were students enrolled in undergraduate programmes in interior architecture (and environmental design) at 34 foundation universities in Istanbul. The sample comprises 166 undergraduate students enrolled at Maltepe University’s Department of Interior Architecture and Istanbul Gedik University’s Department of Interior Architecture and Environmental Design. In the context of quantitative research, the convenience sampling method, one of the random sampling types, was employed to collect data. The Kolb Learning Style Inventory was employed to ascertain the learning styles of the students. The findings of this study indicate that there is no significant difference between the learning styles of students at Maltepe University and Istanbul Gedik University, thereby supporting the research hypothesis.Öğe Non-invasive Raman and XRF study of Mīnā’ī decoration, the first sophisticated painted enamels(Multidisciplinary Digital Publishing Institute (MDPI), 2025) Colomban, Philippe; Şimşek Franci, Gülsu; Ngo, Anh-Tu; Gallet, XavierMīnā’ī wares, crafted during the 12th–13th centuries, represent some of the earliest examples of sophisticated painted enamel decoration by potters. Due to the thinness of these enamel layers, their detailed characterization remains challenging, even with the use of advanced techniques, such as Proton-Induced X-ray Emission (PIXE) analysis and Rutherford Backscattering Spectrometry (RBS). This study provides the first combined non-invasive analysis, using X-ray fluorescence (XRF) and Raman spectroscopy, of five shards attributed to mīnā’ī wares. For comparison, two İznik shards from the 17th century, which feature similarly styled but thicker enamel decorations, were also analyzed. Interestingly, the mīnā’ī paste was found to contain lead and tin, suggesting the use of a lead-rich frit in its composition. This finding was confirmed through micro-destructive analysis, using Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM–EDS). Elements, such as rubidium (Rb), strontium (Sr), yttrium (Y), and zirconium (Zr), produced significant XRF signals and effectively distinguished mīnā’ī wares from İznik wares. A uniform tin-rich glaze, measuring 300–500 µm in thickness, was used as a base layer for the much thinner painted mīnā’ī enamels. The colored areas (blue, turquoise, red, green, black, white, eggplant) revealed the presence of various coloring agents and phases, such as spinels, chromite, and ions like Cu2+ and Co2+, as well as opacifiers like cassiterite and lead–calcium/potassium arsenates. Two distinct cobalt sources were identified: one associated with arsenic and the other with manganese and nickel. These cobalt sources are comparable to those used in İznik pottery. For the first time, boron was detected in the blue enamel of mīnā’ī wares.Öğe Thermodynamics analyses of ionic GO+MXene/EG+water hybrid nanofluid in a circular tube including a novelty vortex generator(Elsevier B.V., 2025) Gürsoy, Emrehan; Gürdal, Mehmet; Yıldırım, FurkanThis research explores the thermo-hydraulic efficiency and entropy generation characteristics of an innovative hybrid nanofluid (GO+MXene/EG+water) flowing through a circular tube, enhanced by a novel vortex generator incorporating dimpled fins with spherical, elliptical, and trapeze geometries placed on wave tapes. The vortex generators effectively disrupted boundary layers, thereby improving thermal performance across all configurations. The novelty of this research lies in the first-time examination of MXene-based hybrid nanofluids in conjunction with vortex generators to assess thermo-hydraulic performance and entropy generation. Due to its excellent thermal conductivity and stability, the hybrid nanofluid was studied under laminar flow conditions, with Reynolds numbers ranging from 500 to 2000. The findings reveal that the GO+MXene/EG+water hybrid nanofluid enhances the convective heat transfer coefficient by 20.32% while increasing the pressure drop by 25.85% compared to the base fluid. Besides, GO+MXene/EG+water hybrid nanofluid reduced the thermal entropy generation at the rate of 60.6%. Among the studied fin geometries, spherical dimpled fins demonstrated the highest heat transfer improvement, with a normalized heat transfer ratio of 1.02, whereas trapeze fins exhibited relatively lower enhancement. This research contributes to the scientific community by providing valuable insights into the optimization of heat exchangers and other industrial thermal systems, facilitating enhanced heat transfer with reduced entropy generation. The study's findings have significant implications for future investigations on the integration of hybrid nanofluids and extended surface heat transfer enhancement techniques. Notably, the results offer a foundation for the development of novel designs that leverage hybrid nanofluids to improve energy efficiency in industrial systems.Öğe Investigation of inspiratory muscle training efficiency before bronchoscopic lung volume reduction: a randomized controlled trial(Sociedad Espanola de Neumologia y Cirugia Toracica (SEPAR), 2025) Pehlivan, Esra; Çetinkaya, Erdoğan; Özcan, Zeynep Betül; Karaahmetoğlu, Fulya Senem; Çörtük, Mustafa; Ataç, Amine; Çınarka, HalitIntroduction: Pulmonary rehabilitation (PR) is recommended prior to bronchoscopic lung volume reduction (BLVR) procedures to optimize patient outcomes. However, there's a lack of clear guidance on PR content. The aim of our study is to examine the effect of adding inspiratory muscle training (IMT) to standard PR before BLVR on exercise capacity, dyspnea, fatigue level and quality of life. Methods: Sixty-four patients were randomly assigned to either the PR Group (PRGr) or the PR with IMT group (IMTGr). Both groups underwent an 8-week standard PR program, including breathing exercises, muscle strengthening, and walking. Additionally, IMTGr received IMT sessions. Outcome measures comprised six-minute walking distance (6MWD), maximal inspiratory and expiratory pressures (MIP, MEP), peripheral muscle strength, modified Medical Research Council dyspnea score, fatigue symptom scale, spirometric parameters, Saint George Quality of Life Questionnaire (SGRQ), International Physical Activity Questionnaire Short Form (IPAQ-SF), and Hospital Anxiety and Depression Scale. Results: Our study found no significant difference in exercise capacity improvement between IMTGr and PRGr. However, IMTGr showed significant improvement in MIP compared to PRGr. Both groups experienced improvements in dyspnea, fatigue, and depression scores, as well as enhancements in 6MWD, MEP, peripheral muscle strength, IPAQ-SF and SGRQ scores. Conclusion: Adding IMT to PR did not show a significant difference between groups among BLVR-eligible patients. However, improved respiratory muscle strength may have positive clinical implications. Further research is needed to explore short and long-term effects.Öğe Does the use of protective face masks affectemporomandibular joint function?(Professional Medical Publications, 2025) Özdemir Görgü, Sena; Yıldırım, Yasin; Kaya, Pınar; Ergezen, Gizem; Uzuner, EdaObjective: Long-term mask use can trigger or exacerbate various health issues. This prospective experimental study evaluated the impact of protective face masks on masseter muscle activity and temporomandibular joint (TMJ) function reported by participants. Methods: This prospective, experimental tudy was conducted to investigate the effect of face masks on TMJ function, we used surface electromyography to assess masseter muscle activity at rest, during maximum contraction of the masseter muscle, and while reading a text. We also evaluated the intensity of the masseter muscle pain using an algometer. The participants underwent these evaluations at the Istanbul Medipol University between July and October 2022. Results: The study included 24 female participants with an average age of 28.5±5.40 years. After at least five hours of daily N95 mask use, a significant increase in masseter muscle activity was observed at rest and during speech (p=0.01; p=0.04, respectively). However, no significant changes in the maximum contraction of masseter muscle or pain threshold were observed (p>0.05). Conclusion: This study found that the use of N95 mask is associated with restricted TMJ movements and discomfort, and an increase in its use is associated with restricted TMJ movements, discomfort, and increased masseter muscle activity. Questions regarding mask-wearing-related habits should be included in the routine lifestyle assessment of patients who report TMJ complaints.Öğe Relationship between nutritional literacy and healthy life skills of university students(John Wiley and Sons Inc, 2025) Karadağ, Gülendam; Bilgiç, Dilek; Öztürk, Nuray; Özdemir, TuğbaHealth literacy is important for maintaining healthy diets and lifestyles. This study examined the relationship between nutrition literacy and healthy life skills of university students. This study was a descriptive and correlational design. The students' Food and Nutrition Literacy Scale knowledge sub-dimension mean score was found to be 10.30 +/- 2.11, at the limited knowledge level, the attitude sub-dimension mean score was 49.32 +/- 7.26, at the limited attitude level, and the behaviour sub-dimension mean score was 31.04 +/- 5.71, at the limited level. The mean Scale of Healthy Life Skills in University Students score of the university students was 62.96 +/- 9.99, at a moderate level. Multiple regression analysis showed that the mean scores obtained from the attitude and behaviour sub-dimensions, studying in the Faculty of Nursing, being 18 years old, and studying in the first or second year were the main variables influencing the healthy life skills of university students. The food and nutrition literacy of the students was limited and their healthy life skills were at a moderate level. As the food and nutrition literacy of the students increased, their healthy life skills became more positive.Öğe Machine learning enhancements for electric vehicles: fault detection through deep Echo State Networks (ESN) model(Institute of Electrical and Electronics Engineers Inc., 2024) Büyükbıçakçı, Erdal; Atlı, Cahit; Dumanlı, Metin; Bulat, Selçuk; Nithiya, C.; Gulati, MonikaElectric vehicles (EVs) are generally considered to be more eco-friendly than traditional forms of mobility.
