Kiral, Adnan; Tonyali, Zeliha; Ergun, Mustafa
With a focus on the dynamic characteristics of the ground motion recorded in Kahramanmaraş, Türkiye, this study provides an overview of the historical seismicity of the Eastern Anatolian Fault Zone (EAFZ) as well as the characteristics of the Pazarcik and Elbistan earthquakes (Mw=7.7 and Mw=7.6) that resulted in property loss and casualties on February 6, 2023. Analyzing the ground motion and local site effects for the earthquake region has been the subject of extensive research in the past. Ground Motion Prediction Equations (GMPEs) are one of the evaluation techniques utilised in the literature. Previous research employing this approach and other techniques suggested that the earthquake region’s geotechnical and seismological conditions are complicated, particularly in Hatay City. In this study, to further investigate the ground motions, six GMPEs, which were previously proposed for the USA, Europe and the Middle East, are adopted. The findings of this study are integrated with those from previous research for comprehensive assessments. This study shows that the PGA of the Kahramanmaraş earthquakes cannot be fully predicted using GMPEs, which use epicentral distance (Repi) in the equation. As a result, further research into rupture distance (Rrup) or Joyner-Boore distance (Rjb)-based equations is necessary. Also, the complexity of the region (i.e., irregularities present in alluvial deposits) and the high PGA values could be responsible for such a result. This study emphasizes the region’s need to have more sophisticated GMPEs in the future.

The objective of this study is to utilize artificial intelligence techniques for the diagnosis of complications and diseases that may arise after liver transplantation, as well as for the identification of patients in need of transplantation. To achieve this, an interface was developed to collect patient information from Atatürk University Research Hospital, specifically focusing on individuals who have undergone liver transplantation. The collected data were subsequently entered into a comprehensive database. Additionally, relevant patient information was obtained through the hospital’s information processing system, which was used to create a data pool. The classification of data was based on four dependent variables, namely, the presence or absence of death (“exitus”), recurrence location, tumor recurrence, and cause of death. Techniques such as Principal Component Analysis and Linear Discriminant Analysis (LDA) were employed to enhance the performance of the models. Among the various methods employed, the LDA method consistently yielded superior results in terms of accuracy during k-fold cross-validation. Following k-fold cross-validation, the model achieved the highest accuracy of 98% for the dependent variable “exitus”. For the dependent variable “recurrence location”, the highest accuracy obtained after k-fold cross-validation was 91%. Furthermore, the highest accuracy of 99% was achieved for both the dependent variables “tumor recurrence” and “cause of death” after k-fold cross-validation.

Ertürk, Ömer; Can, Zehra; Yaman, Mustafa
This work was accomplished to establish the chemical components and bioactivity potential of the nest materials of Polistes nimpha (Christ), Polistes dominula (Christ), and Vespa crabro (L.). The biological and chemical compounds of materials and their molecular functionalities were detected using FRAP (ferric reducing antioxidant power) method, DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) free radical method, and Energy Dispersive X-Ray Analysis. Finally, the bioactivity potentials of nest extracts were assayed and phenolic components were determined. C, N, O, Na, Ca, K, Mg, Al, Si are the elemental components of the nest materials. All nest extracts of three species had high biological activity against nine bacteria and one fungus causing common infections. The maximum antibacterial and antifungal activity was seen when gram-negative Pseudomonas aeruginosa, gram-positive Bacillus cereus, and gram-positive Candida albicans were exposed to ethanol extracts of nest samples in 25 μL. High antioxidant activity can be found in the nest extracts. These extracts might help researchers find novel antifungal and antibacterial substances.

This study aimed to investigate the effects of 8 weeks of core and dynamic balance training on reaction speed and agility in A-team basketball players. A total of 29 male basketball players participated in the study, with athletes divided into two groups: experimental (n=14) and control (n=15). The experimental group received core and dynamic balance training three days a week in addition to technical and tactical basketball training for 8 weeks, while the control group received only technical and tactical training for the same duration. Body fat percentage (measured with Tanita BC 418-ma), the lane agility drill, and reactive shuttle run tests were conducted before and after the training as performance measurements. When analyzing the pre-test and post-test results regarding the effects of core and dynamic balance training on the motoric characteristics of players in the Turkish Basketball League, no significant difference was found in the Reactive Shuttle Run test for the experimental group (p<0.05). However, significant differences were observed in both the experimental and control groups for the other tests (p>0.05). The findings indicated that core and dynamic balance exercises, when added to basketball training, did not show an additional effect on the athletes in the experimental group, unlike the control group. However, no difference was found in the results of the Reactive Shuttle Run test between the two groups.

Uzun, Oguzhan; Abdioglu, Murat; Ozturk, U. Kemal
This study investigates flux trapping in bulk YBaCuOx (YBCO) high-temperature superconductors (HTS) under various permanent magnet configurations (PMCs) through both experimental and numerical methods. A finite element method (FEM) based on the H-formulation of Maxwell's equations is employed to simulate the HTS-PM interaction, showing good agreement with experimental results in peak trapped flux density values. The maximum trapped flux densities for PMC-1, PMC-2, PMC-3, and PMC-4 were measured as 207 mT, 359 mT, 392 mT, and 478 mT, respectively, demonstrating the significance of PMC design in optimising flux trapping in HTS materials. Enhanced flux trapping was observed with configurations including additional permanent magnets, such as PMC-2 and PMC-4, yielding trapped flux efficiencies of 77.5 % and 55.0 %, respectively. Obtained results in trapped flux efficiency are very impressive as compared to a value of 23 % trapped flux efficiency in literature in which a solenoid magnet with a 3 T peak value of magnetic flux density is used to trap a magnetic field in the HTS. The magnetic flux trapping methodology of this research is very effective for magnetic bearing applications with self-stabilisation in which high magnetic fields are not needed since it doesn't need any magnetic field sources with complex structures, such as coils, to facilitate the magnetic field trapping in the HTSs.

Seven, Ahmet; Sari, Ebru Sönmez; Semerci, Vahide
Aim: To determine the perceptions of good death and death literacy levels of Turkish nurses working in palliative care services and the factors affecting their perceptions of good death. Background: Death literacy is defined as the acquisition of the knowledge and skills necessary to understand end-of-life care and contribute to a good death. Methods: For this cross-sectional study, sample consisted of 162 Turkish nurses working in palliative care services. The data were collected using the Socio-demographic Information Form, Good Death Scale (GDS), and Death Literacy Index (DLI). The data were analyzed by Pearson correlation, independent sample t test, and one-way ANOVA. Hierarchical regression analysis was performed to determine the predictors of good death perception. The STROBE checklist was used in the study. Findings: The mean GDS score was 59.53 ± 4.49, and the mean DLI score was 100.70 ± 12.11. It was determined that those who are older, male, married, have worked longer in the clinic, and have knowledge about a good death have higher average scores on the GDS. The models explain 91.8% of the variance in the perception of good death. Discussion: Our study shows that as death literacy increases, nurses’ perceptions of a good death tend to decrease. This situation suggests that as nurses’ knowledge and awareness of death increase, the inadequacies of the healthcare system and the impact of limited resources may cause them to develop a more negative perception. Death literacy in nurses is a new concept, and further studies are needed in different cultures. Conclusions: In the study, it was observed that death literacy levels and good death perceptions of nurses were above average, and as the death literacy level of nurses increased, their good death perceptions decreased. Age, gender, marital status, working time in the clinic and knowledge about good death affect the perception of good death of nurses working in palliative care. Implications for nursing: By improving their understanding of death literacy and the principles of a good death, palliative care nurses can achieve greater job satisfaction and develop a more positive attitude toward end-of-life care. In addition, systematically incorporating death literacy into nursing education curricula and continuing professional development programs, and the establishment of evidence-based clinical guidelines and standard care protocols will improve the quality of palliative care services.

Gerçek, Yusuf Can; Kutlu, Naciye; Çelik, Saffet; Bayram, Sinan; Kırkıncı, Seran; Ecem Bayram, Nesrin
Deep eutectic solvents (DESs) have been widely used in food processing in recent years, owing to their remarkable advantages. The aim of this study was to evaluate the potential of DESs for the recovery of bioactive components from chokeberry fruit. First, among the 10 different DESs, the DES that extracted the highest total individual phenolic content (TIPC) from chokeberry was determined. Then, ultrasonically assisted extraction conditions (ultrasonic amplitude, time, and temperature) were optimized by response surface methodology to obtain the maximum amount of TIPC using this DES. According to the results obtained, the natural deep eutectic solvent (NaDES) choline chloride: acetic acid (1:2, 30% water content) provided the highest yield for TIPC extraction and the optimum conditions for maximum TIPC extraction were determined as 100% for ultrasonic amplitude, 50 °C for temperature and 60 min for sonication time. The TIPC content of the extracts prepared with this NaDES was determined between 1740.26 and 3703.14 mg/kg. In addition, the individual organic acid and individual anthocyanin contents of the NaDES extracts, as well as their antioxidant and antimicrobial activities, were determined. Chlorogenic acid (1392.351–2361.48 mg/kg) among phenolic compounds, pyruvic acid (9361.35–47398.04 mg/kg) among organic acids and kuromanin chloride (69748.13–134668.24 mg/kg) among anthocyanins were the dominant compounds in NaDES extracts. However, the extracts showed varying levels of antimicrobial activity against Gram (+) bacteria, Gram (−) bacteria, and yeast-like fungi (Candida strains). Finally, the Blue Applicability Grade Index (BAGI) was used to evaluate the practicality/blueness potential of the chromatographic method used to determine the anthocyanin composition of the DES extracts. In conclusion, NaDES (choline chloride:acetic acid) can be an alternative solvent for the recovery of some individual phenolics, organic acids and anthocyanins under different extraction conditions. In addition, the use of NaDES in the recovery of various functional compounds needed in food, cosmetics, pharmaceuticals, etc., is important for the promotion of sustainability and green technology.

Karadas, Yasemin AY; Sahin, Sibel Yilmaz
Introduction: Bariatric surgery is a treatment method that is gaining popularity in the world and Turkey due to the inadequacy of traditional methods in obesity treatment in achieving the desired results and the need for long-term treatment coverage. This study aimed to investigate the effect of music on postoperative nausea and vomiting (PONV) management and patient satisfaction in individuals undergoing bariatric surgery. Methods: A total of 48 patients, 24 in the experimental group and 24 in the control group, were included in this study. Music therapy was applied to the experimental group participants just before the 2nd and 6th hours after surgery, while the control group participants were routinely monitored without intervention. Results: There was no significant difference between the experimental and control groups in terms of PONV severity and Postoperative Nausea and Vomiting Impact Scale scores at the 2nd, 4th, 6th, 12th, and 24th hours (p > 0.05). Music therapy was associated with statistically significantly higher nurse satisfaction in the experimental group (p < 0.05). Conclusion: The results of this study indicate that music therapy has no significant effect on PONV after bariatric surgery but is effective in increasing patient satisfaction.

This study aimed to examine the relationship between orthorexia nervosa and body image, physical activity level, and the Big Five personality traits among non-clinical adult individuals. Based on the relational survey model, the research sample consisted of 350 undergraduate students (205 females, 145 males) enrolled in various departments at a public university. A convenience sampling method was used, and participants’ ages ranged from 18 to 30 years (M = 20.64, SD = 2.07). Data were collected using a personal information form, the ORTO-15 Scale, the Big Five Personality Test (short version), the Body Appreciation Scale, and the International Physical Activity Questionnaire. Pearson correlation and regression analyses were conducted. The findings revealed that conscientiousness, openness to experience, and body image were significantly associated with orthorexic tendencies. As levels of conscientiousness and openness to experience increased, behaviors related to orthorexia nervosa also tended to increase. Similarly, individuals with higher body image satisfaction exhibited more pronounced orthorexic tendencies. These results suggest that individual differences may play a determining role not only in healthy lifestyle choices but also in the potential development of these choices into pathological behaviors.

Uslu, Emin; Yilmaz, Galip; Uyar, Mehmet
This study explores the innovative dual-purpose use of carbon fiber, functioning both as a structural and a heating element, expanding its potential in hybrid composites. A prototype composite was fabricated using the vacuum infusion process, featuring a single carbon fiber layer at the core for dual-purpose and two outer layers of glass fiber. Electrical heating tests revealed a stable relationship between voltage, resistance, power, and temperature, demonstrating efficient heat generation as the voltage increased. Thermal imaging confirmed uniform heat distribution with minor variations. Free vibration tests evaluated the composite's dynamic behavior under various electro-thermal conditions. Results showed that increasing temperature reduced the natural frequencies, particularly in the second vibration mode. Changes in Rayleigh damping coefficients at higher temperatures highlighted the composite's sensitivity to thermal inputs. These findings underline the potential of hybrid composites for advanced applications like turbine blades and aerospace components, where multifunctionality, self-heating, and vibration control are critical.

The growing demand for environmentally friendly and cost-effective approaches has accelerated the development of sustainable methods for the synthesis of reduced graphene oxide (rGO). In this study, urea was utilized as a green reducing agent for rGO synthesis, offering an alternative to conventional toxic chemicals. The synthesized rGO was comprehensively characterized using FTIR, SEM-EDS, Raman spectroscopy, XRD, BET analysis, zeta potential, and conductivity measurements. These analyses revealed key functional, structural, and morphological properties, including surface functional groups, elemental composition, carbon-to-oxygen (C/O) ratio, particle size (PS), crystallite size (CS), specific surface area (SSA), zeta potential (ZP), thermal conductivity (TC), and electrical conductivity (EC). Process optimization was performed using the Taguchi L4(23) orthogonal array design across nine quality parameters. Under optimal conditions, notable enhancements were achieved: C/O ratio increased by 108%, ID/IG ratio by 164%, I2D/IG ratio by 26%, CS by 75%, and SSA by 134%, while PS was reduced by 37%. Furthermore, ZP and TC increased by 58% and 33%, respectively, whereas EC was reduced by 97%. These findings demonstrate the potential of urea as a sustainable and effective reducing agent in the production of high-performance rGO materials.

Karakaya, Umut Can; Ceyhan, Mehmet Ali
Background: This study examines the changes in performance enhancement attitudes and sports supplement belief levels among sports sciences faculty students after education on ergogenic aids and anti-doping practices. In the highly competitive environment of modern sports, nutrition and ergogenic aids are crucial in enhancing athletic performance and preventing injuries. However, research in this area is limited, and existing literature emphasizes the need to explore the relationship between education and these topics. Methods: The study employed an experimental design using a one-group pre-test and post-test method. The research group comprised 61 students (24 female and 37 male) from the Faculty of Sport Sciences at Bayburt University. Data collection tools included the “Personal Information Form,” the “Performance Enhancement Attitude Scale (PEAS),” and the “Sports Supplement Belief Scale (SSBS).” Data were collected via Google Forms and analyzed using SPSS 26.0 software. The skewness and kurtosis values were calculated to assess the data distribution, and parametric tests, including t-tests and ANOVA, were applied. Results: The findings revealed that education on ergogenic aids and anti-doping practices significantly improved students’ performance-enhancement attitudes. For example, PEAS scores increased from a pre-test mean of 38.74 to a post-test mean of 44.13 (p < 0.05), representing a change of approximately 13.91%. However, no significant changes were observed in SSBS scores. This suggests that students’ beliefs regarding sports supplements may be shaped by prior knowledge and experiences, making them less influenced by the educational intervention. Conclusions: This study demonstrates that education on ergogenic aids and anti-doping practices can positively influence students’ performance-enhancement attitudes. However, more in-depth educational programs may be required to impact beliefs about sports supplements. These findings can guide the development of more effective educational programs to enhance athletic performance and safeguard athlete health. By providing evidence-based insights, this study significantly contributes to the existing literature and supports the development of policies and educational initiatives in anti-doping and athlete education.

Lotfieghlim, Armin; Sekban, Hayriye Tuğba; Başçi, Abdullah
In this paper, a Lyapunov-based adaptive state space controller is designed to realize liquid level control in a coupled tank system. The proposed controller is a kind of adaptive control system that combines the principles of state space representation with Lyapunov stability theory to estimate unknown parameters and control a dynamic system. This approach ensures that the system remains stable even when the exact model parameters are unknown or change over time. Moreover, in order to test the performance of the proposed controller, proportional integral (PI) + feedforward (FF) controller is also applied to the same system under the same conditions and the results are compared. The results show that the proposed controller outperforms the PI + FF controller in terms of system response parameters such as rise time, percent overshoot, and settling time. On the other hand, when the error performance metrics integral squared error (ISE), integral time-weighted squared error (ITSE), integral time-weighted absolute error (ITAE), and integral absolute error (IAE) are evaluated, it is seen that the same situation is also realized here, and the proposed controller follows the reference signals with lower error values in real-time studies for different reference signals.

As the use of artificial intelligence increases in areas where people are active in our daily lives such as education and health, the comparison of human and artificial intelligence has started to be discussed. Many artificial intelligence programmes are commanded by humans and artificial intelligence creates products in line with expectations. In this study, it is aimed to compare the drawings of pre-service science teachers about the concept of universe with the universe visuals created by artificial intelligence. Case study was selected as the research model. The study group consisted of 24 pre-service science teachers studying in the 2nd and 4th grades of science teaching. The worksheet prepared by the researchers and the received expert opinion was used as a data collection tool. During the application process, pre-service teachers made drawings related to the concept of universe and described these drawings during two lesson hours. Then, they made drawings related to the concept of universe of artificial intelligence with the descriptions they entered into Microsoft Bing Search application. As a result, it was determined that pre-service teachers had different views in their drawings about the concept of universe. It is seen that the drawings of the pre-service teachers about the concept of universe and the visuals created by artificial intelligence are mostly like each other. In half of the drawings, the universe drawings of the pre-service teachers were more comprehensive, while in half of the drawings, artificial intelligence made more comprehensive drawings. Based on this result, it can be said that human perception and artificial intelligence products are in parallel with each other. Various suggestions were presented in line with the results of the study.

This study investigates pesticide, antibiotic, and heavy metal levels in Bayburt and the Upper Çoruh Valley honey. Thirteen honey samples were collected from different apiaries managed by stationary and migratory beekeepers. These samples were analysed for heavy metals (Fe, Cu, Zn, Cd, Pb), antibiotics, pesticides, and chemical residues such as naphthalene. The results revealed that lead (Pb) levels exceeded international food safety standards in 2 honey samples, while pesticide residues were detected in 5 samples. Additionally, antibiotic residues were found in 6 samples, including sulfamethazine, tetracycline, and streptomycin. However, no naphthalene was detected in any of the samples. These findings highlight the importance of stricter regulations and monitoring systems to control chemical use in beekeeping practices. Enhancing awareness among beekeepers regarding the risks associated with pesticide and antibiotic use is crucial for improving honey quality and ensuring the health of beekeepers and consumers. The adoption of safer practices and adherence to guidelines are necessary to mitigate these health hazards.
