Starting route: Istanbul street food
(Elsevier B.V., 2025) Yarmacı Güvenç, Nihan; Evren, Seray; Köz, Ela Nazlı
The gastronomy routes, which have the functions of diversifying tourism products, increasing the gastronomy tourism quality, creating attraction, and contributing social and economic development, are thought to be especially necessary in Istanbul. Integrating Istanbul's historical, cultural, and natural structure with the city's street food and turning them into a route is considered beneficial in various aspects. In this context the aim of the research is to create Istanbul street food routes, considering the outline formed within existing gastronomy-themed routes. In order to achieve the goal, the data were gathered from 36 gastronomy-themed routes in Istanbul presented on TripAdvisor were analyzed. The findings such as duration and width of routes, language options offered, cultural and historical sites visited and passed by in the routes, presented food categories, street food varieties according to districts, and experience offered are used to develop suggestions for Istanbul street food route.
The effectiveness of teaching English with makey makey in children with autism spectrum disorder
(OCERINT International Organization Center of Academic Research, 2020) Aydoğan, Aslan; Kocakoyun Aydoğan, Şenay
In this study, activities programmed with Scratch Program prepared with Makey Makey were prepared. Makey Makey is a new technology that enables the creation of various sounds by coding the keys on the device after connection to the computer via USB. It is aimed that the practitioners produce different products, both in terms of electrical conductivity and in line with their own needs. It is potentially exciting for students and practitioners because it meets the requirements of easy operation and low cost. In the embedded teaching method, which is made by reducing the clue gradually, the effectiveness of teaching English to children with autism spectrum disorder was investigated. In the study, the multiple - polling model was used for single-subject research models. The persistence of learning was controlled by monitoring sessions at the 1st, 2nd, and 4th weeks after training was completed, and the generalization effect of the research was examined as pre-test and post-test. Collective and daily polling, teaching, monitoring, and generalization sessions were organized during the research process. All sessions were conducted as one-to-one instruction. In the research, inter-observer reliability and application reliability data were collected. The findings of the study reveal that embedded teaching with the gradual reduction of the clue in the activities programmed with the Scratch Program prepared with Makey Makey is effective in teaching English concepts to children with autism who need special education. It also shows whether persistence can be maintained through monitoring sessions after the teaching sessions and that generalization sessions are effective in generalizing what is learned to different people, tools, and environments.
Can Vitamin D reduce the need for SSRI by modulating serotonin synthesis? : a review of recent literature
(Springer Nature, 2025) Bostan, Zekiye Zeynep; Bulut, Melike Sare; Gezmen Karadağ, Makbule
Purpose of Review: This study aims to analyze the effects of vitamin D on serotonin synthesis, release, and function in the brain, and to explore its relationship with various psychiatric disorders. 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.
Thermodynamics analyses of ionic GO plus MXene/EG plus water hybrid nanofluid in a circular tube including a novelty vortex generator
(Elsevier Science SA, 2025) Gürsoy, Emrehan; Gürdal, Mehmet; Yıldırım, Furkan
This 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.
The effect of internet addiction on surgical nurses' malpractice tendencies: Turkish sample
(Springer Nature, 2025) Gezginci Akpınar, Elif; Orhan, Büşra Nur; Göktaş, Sonay
Background 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.
