Bingöl, Nuray; İşcan Ayyildiz, Neşe; Aktepe Coşar, Dilan
Purpose: Health-seeking behaviors of individuals who have epilepsy might affect the treatment of the disease, recovery process, and self-care activities. The present study was conducted to determine the health-seeking behaviors of individuals who have epilepsy. Materials and methods: The present study was conducted in a descriptive and cross-sectional design with 190 epilepsy patients who applied to the Neurology Clinic in the north and east of Turkey between April 2023 and January 2024. The data of the study were collected by using the Introductory Data Form, Health-Seeking Behavior Scale (HSBS). The IBM SPSS 27 software, variance analysis, Tamhane T2, ANOVA Test, Tukey Test, and Multiple Regression Analysis were used to evaluate the study data. Results: The mean score of the online health-seeking behavior sub-dimension of the Health-Seeking Behavior Scale of the individuals who had epilepsy was found to be 13.32 ± 5.40, the mean score of the professional health-seeking behavior sub-dimension was 9.92 ± 2.75, and the mean score of the traditional health-seeking behavior sub-dimension was 8.46 ± 3.29. No significant differences were detected between individuals’ sex, seizure types, and health-seeking behaviors, and a significant difference was detected between marital status, educational status, place of residence, occupation, income level, seizure frequency, and medication use status and health-seeking behaviors (p < 0.05). According to the multiple linear regression analysis that was used to examine the effects of sociodemographic characteristics of individuals with epilepsy on health seeking behavior scale scores, it was found that sociodemographic characteristics such as educational status, place of residence, marital status, and age significantly affected online, professional, and traditional health seeking behavior scores. Conclusion: In conclusion, it was found in the present study that the online health-seeking behavior of the individuals who had epilepsy was higher than other health-seeking behaviors. The health-seeking behaviors of patients were affected by sociodemographic characteristics (e.g., marital status, educational status, place of residence, occupation, income level, seizure frequency, and medication use). It is of great importance to conduct larger future studies on individuals who have epilepsy and are seeking traditional treatment for epileptic seizures because the sources from which health information is obtained might affect the diagnosis, treatment, and recovery processes.

Tunç, Merve Tuğçe; Genç, Berna; Karataş, Şeyda Merve
In this study, the fermentation process of bioethanol production conditions were optimized by response surface methodology. Mulberry molasses production waste was used as the only carbon source for yeast fermentation to produce bioethanol. Hydrodistillation (HD) and ohmic-assisted hydrodistillation (OAHD) methods were employed to concentrate the bioethanol. Fermentation time (48–168 h), waste matter rate (5–45%) and pH (5–7) were selected as independent variables. Alcohol concentration was treated as the response. Optimum fermentation conditions were determined as 96.894 h fermentation time, 45% waste ratio and pH 7. At these optimum conditions, alcohol concentration was determined as 3.77 ± 0.33%. While the distillate obtained in the HD method contained 22.50 ± 1.89% alcohol, it showed 27.72 ± 0.24% in the OAHD method. The energy consumption values for OAHD and HD was 2.92 ± 0.51 and 53.24 ± 1.74 Wh/mL bioethanol, respectively. Results of study showed that the OAHD could be a cost-effective and green method to distillation of bioethanol from mulberry molasses waste.

Avci, Ibrahim
Purpose – The goal of the research is to determine the perceived efficacy of brand boycotting campaigns by Turkish consumers, as well as the effects of social pressure on boycott intention, the mediating role of social media, and the moderating role of discount sensitivity on these effects. Theoretical framework – The research idea and model were developed following previous boycott research (Shin and Yoon, 2018; Muhamad et al., 2018; Asnawi et al., 2019; Zhai and Luo, 2023). Design/methodology/approach – Data were collected from Turkish consumers using the convenience sampling method and an online survey. Using data from 417 consumers, the research hypotheses were investigated using structural equation modeling. Findings – According to the findings, perceived efficacy and social pressure have a significant effect on consumers’ boycott intentions, with social media playing a partial mediating role. Furthermore, consumers’ sensitivity to discounts offered by boycotted firms was found to have a moderating effect on the relationship between social pressure and boycott intention. Practical & social implications of research – Managers of boycotted brands should devise appropriate marketing strategies to minimize damage. Given the importance of social media in boycotts, it is imperative that brands actively use social media as a communication channel. Originality/value – The fact that the paper examines the idea of boycotting in the context of both social media and consumer discount sensitivity demonstrates the importance of the research and its contribution to filling a gap in the literature.

Alemdag, Selçuk; Yalvaç, Sefa; Bjelotomić Oršulić, Olga; Kara, Osman; Zeybek, Halil İbrahim; Bostanci, Hasan Tahsin; Markovinović, Danko
The escalating occurrence of landslides has drawn increasing attention from the scientific community, primarily driven by a combination of natural phenomena such as unpredictable seismic events, intensified precipitation, and rapid snowmelt attributable to climate fluctuations, compounded by inadequacies in engineering practices during site selection. Within the scope of this investigation, contemporary geodetic techniques using the GNSS were employed to monitor structural and surface deformations in and around a hospital edifice situated within an ancient fossil landslide region. Additionally, inclinometer measurements facilitated the determination of slip circle parameters. A subsequent analysis integrated these datasets to scrutinize both the hospital structure and its surrounding slopes. In addition to the finite element method, four different limit equilibrium methods (Bishop, GLE–Morgenstern–Price, Spencer, and Janbu) were used in the evaluation of stability. Since the safety number determined in all analyses was <1, it was determined that the slope containing the hospital building was unstable. The movement has occurred again due to the additional load created by the hospital building built on the currently stable slope, the effect of surface and groundwater, and the improperly designed road route. As a result of geodetic monitoring, it was determined that the sliding speed on the surface was in the N-E direction and was approximately 3 cm, and this situation almost coincided with inclinometer measurements.

Köseoğlu, Ali; Altun, Fatma; Şahin, Rıdvan
Fuzzy sets (FSs) are a flexible and powerful tool for reasoning about uncertain situations that cannot be adequately expressed by classical sets. However, these sets fall short in two areas. The first is the reliability of this tool. Z-numbers are an extension of fuzzy numbers that improve the representation of uncertainty by combining two important components: restriction and reliability. The second is the problems that need to be solved simultaneously. Complex fuzzy sets (CFSs) overcome this problem by adding a second dimension to fuzzy numbers and simultaneously adding connected elements to the solution. However, they are insufficient when it comes to problems involving these two areas. We cannot express real-life problems that need to be solved at the same time and require the reliability of the information given with any set approach given in the literature. Therefore, in this study, we propose the complex fuzzy Z-number set (CFZNS), a generalization of Z-numbers and CFS, which fills this gap. We provide the operational laws of CFZNS along with some properties. Additionally, we define two essential aggregation operators called complex fuzzy Z-number weighted averaging (CFZNWA) and complex fuzzy Z-number weighted geometric (CFZNWG) operators. Then, we present an illustrative example to demonstrate the proficiency and superiority of the proposed approach. Thus, we process multiple fuzzy expressions simultaneously and take into account the reliability of these fuzzy expressions in applications. Furthermore, we compare the results with the existing set operations to confirm the advantages and demonstrate the efficiency of the proposed approach. Considering the simultaneous expression of fuzzy statements, this study can serve as a foundation for new aggregation operators and decision-making problems and can be extended to many new applications such as pattern recognition and clustering.

Nacar, Sinan; Şan, Murat; Kankal, Murat; Okkan, Umut
This study investigates the possible effects of climate change on temperature and precipitation variables in the Eastern Black Sea Basin, Türkiye’s wettest and flood-prone region. The outputs of three GCMs under historical, RCP4.5, and RCP8.5 scenarios were downscaled to regional scale using the multivariate adaptive regression splines method. The future monthly temperature and precipitation for 12 stations in the basin were projected for three periods: the 2030s (2021–2050), 2060s (2051–2080), and 2090s (2081–2100). In addition to relative changes, high and low groups and intra-period trends were analyzed for the first time using innovative methods. For the pessimistic scenario, an increase of 3.5 °C in the interior and 3.0 °C in the coastal areas of the basin is projected. For the optimistic scenario, these values are expected to be 2.5 and 2.0 °C, respectively. A decrease in precipitation is projected for the interior region, and a significant increase is expected for the eastern and coastal areas of the basin, especially in spring. This result indicates that floods will occur frequently coastal areas of the basin in the coming periods. Also, although the monotonic trends of temperatures during periods are higher than precipitation in interior regions, these regions may have more uncertainty as their trends are in different directions of low and high groups of different scenarios and GCMs and contribute to all trends, especially precipitation.

This study aimed to enhance the oxygen barrier properties of polylactic acid (PLA) film, a biodegradable packaging material with high oxygen permeability (OP). Bi-layer films were produced by coating thermoplastic starch (TPS) onto PLA films in various ratios while maintaining constant film thickness. The mechanical, optical, barrier, thermal, hydrophobicity, moisture sorption, and microstructural properties of the films were analyzed. Increasing the TPS ratio elevated moisture content (MC), water uptake, solubility, and opacity while enhancing UV barrier properties. TPS coating reduced tensile and burst strength but increased the burst deformation of the bi-layer films. Bi-layer film production resulted in a water vapor permeability increase of 59.26%–94.44% compared with neat PLA while decreasing OP by 2.52%–29.66%. The equilibrium moisture content (EMC) rose with higher TPS ratios, displaying type II isotherms. FTIR analysis indicated no chemical interactions between PLA and TPS. Increasing the TPS ratio decreased PLA crystallinity, supporting the mechanical and barrier properties of the bi-layer films. Neat and bi-layer films exhibited smooth, homogeneous surfaces, with a visible interface in the cross-section of the bi-layer films. In conclusion, TPS shows promise as an alternative to improve oxygen barrier properties in PLA films without adversely affecting other properties.

Hasırcı Tuğcu, Zeynep; Kuzulugil, Kenan; Çavdar, İsmail Hakkı
Vehicle-to-vehicle (V2V) communication is one of the promising communication applications designed to optimize traffic conditions and has played a crucial role in the improvement of intelligent transportation technologies. Since there is still some uncertainty regarding generalized models that provide a more accurate representation of propagation environments, the existing literature emphasizes the need for additional experimental studies in various countries and propagation environments. This study aims to investigate the low-density and high-density characteristics of V2V channels for highway, suburban, and urban propagation environments in Türkiye. Thus, first, channel measurements were conducted for all propagation scenarios. Then, after the estimation of path loss parameters, the best-fitted path loss model was determined for each propagation scenario by comparing log-distance, two-ray, and log-ray models. It was observed that the log-ray model offered remarkably better performance than the two-ray model, especially in the majority of scenarios with two-ray characteristics. In addition, small-scale modeling and shadowing were also examined, and the outcomes were compared to relevant literature. Last, generalized path loss models were developed for six propagation scenarios and compared with previous studies. Providing additional experimental data on the impact of traffic and road environments that vary across countries on the V2V channel, this study not only validated and compared existing propagation models but also improved the representing accuracy and generalizability of the newly proposed propagation models. Here, all findings were presented in detail to support the motivation of the research.

There are different strains of laboratory mouse used in many different fields. These strains differ anatomically. In order to determine these anatomical differences, shape analysis was conducted according to species. CD-1, C57bl/6 and Balb-c strains were preferred to study these differences. Forty-eight adult mouse strains belonging to these strains were utilized. The bones were photographed and geometric morphometry was applied to these photographs. Principal Component Analysis was applied to determine shape variations. In Principal component 1 for cranium, CD-1 and C57bl/6 strain groups showed different shape variations, while Balb-c strain group showed similar shape variations to the other strain groups. Principal Component 1 for the mandible separated the CD-1 and C57bl/6 strain groups in terms of shape variation. Principal Component 2 explained most of the variation between the C57bl/6 and CD-1 lineage groups. In PC1 for molars, the CD-1 group showed a different shape variation from the other groups. Mahalanobis distances and Procrustes distances were measured using Canonical variance analysis to explain the differences between the lineage groups. These measurements were statistically significant. For cranium, in canonical variate 1, CD-1 group of mouse and Balb-c group of mouse were separated from each other. In canonical variate 2, C57bl/6 group of mouse were separated from the other groups. For mandible, Balb-c group of mouse in canonical variate 1 and CD-1 group of mouse in canonical variate 2 were separated from the other groups. For molars, CD-1 group of mouse in canonical variate 1 and Balb-c group of mouse in canonical variate 2 were separated from the other groups. It was thought that these anatomical differences could be caused by genotypic factors as well as dietary differences and many different habits that would affect the way their muscles work.

The aim of this study is twofold: (1) to identify differences in certain anaerobic parameters (10m sprint, 30m sprint, anaerobic power, and Illinois agility tests) between professional and amateur soccer players, and (2) to determine whether there is a difference in the ACTN3 gene polymorphism between professional and amateur soccer players. Ultimately, the goal is to reveal which parameters contribute to the differentiation in these two aspects. A total of 133 volunteer soccer players, including 71 professionals and 62 amateurs, participated in the research. DNA extraction from buccal epithelial cells was performed using a commercial kit to determine the genetic background of the athletes, and Real-Time PCR was conducted for genotyping. Statistical analysis of the findings obtained from the test results was performed using the SPSS 23 (SPSS Inc., Chicago, IL, USA) package program. The homogeneity of variance of the data was assessed using the Levene Test, and normal distribution analyses were conducted using the Shapiro-Wilk Test. Chi-square and Mann-Whitney U tests were employed for parameter analysis. The significance level was set at p<0.05. Evaluation of the data in our study revealed no statistically significant difference in ACTN3 rs1815739 gene polymorphism between the groups (p>0.05). However, there is a statistically significant difference in anaerobic parameters (10m sprint, 30m sprint, and anaerobic power) except for the Illinois test (p<0.05). In conclusion, our study found that gene polymorphism is not a differentiating factor between professional and amateur soccer players, but speed (10m and 30m) and anaerobic power parameters are differentiating factors.

Bekiroğlu, Sultan; Özdemir, Mehmet; Özyürek, Ercan; Çakır, Günay
Success of model forests, which are organized to support sustainable management of forests in collaboration with environmental, social, and economic forces on forest-based large territories, depends on the development of civil society index dimensions defined as “stakeholder participation,” “organizational structure,” “environment,” “values,” and “impact.” In this study, which was carried out within the scope of Yalova Model Forest, situation analysis strengths, weaknesses, opportunities, and threats analysis was used as a method. Literature and official documents, expert opinions on “stakeholder engagement,” and data obtained through a 30-question survey were used as material. In this study, “historical development,”“legal regulations,” “activities” of Yalova Model Forest and weaknesses, strengths, opportunities, threats of civil society index and strategies pertaining to them were determined. Strengths, weaknesses, opportunities, and threats analysis was conducted by forming four separate focus groups for four dimensions of the Yalova Model Forest civil society index. According to the results of this study, the stakeholder participation dimension was concluded to be exceedingly inadequate. This is evidenced by advocate stakeholders’ insufficient participation rates in activities, absence of adverse stakeholders in this reconciliation platform, and the fact that 99% of dormant–indifferent stakeholders are unaware of this organization’s existence. Therefore, stakeholder participation dimension should be strengthened and the strategic plans that will be implemented should be prepared with the participation of stakeholders. Otherwise, Yalova Model Forest’s existence, as a civil society organization, will be jeopardized. However, active advocate stakeholders’ enthusiasm about resolving problems is reassuring for the future of Yalova Model Forest.

Insani, Nur; Ibrahim, Zumiyati Sanu; Karimullah, Suud Sarim; Gönan, Yavuz; Sulastri
This intersectional study investigates the harmonisation of Islamic law and human rights in the context of empowering Muslim women through Islamic economics. This study applies an intersectional approach in carrying out the library research method with literature analysis carried out integratively and comprehensively to explore and review various literature sources relevant to the research topic, including journal articles, books, research reports, policy documents, and other related sources of information. The results show that harmonisation between Islamic law and human rights in empowering Muslim women through Islamic economics significantly impacts achieving gender equality and supporting sustainable development. The complexity of Muslim women's identities influenced by factors such as religion, gender, and social class demands a holistic and integrated policy approach in the economy. While the Islamic economy offers great potential to enhance the role of women as agents of change and key drivers of economic development, the incompatibility between Islamic law and human rights conventions and issues of gender inequality points to the need for more inclusive legal and policy reforms. Identifying and recognising these challenges underscores the importance of adopting a comprehensive and coordinated approach. Specific measures that need to be strengthened include inter-agency cooperation, legal and policy reforms to support better gender equality, capacity building of women in the Islamic economic sector, and raising public awareness on the importance of women's empowerment. As such, this study enriches the academic literature and offers practical guidance for policymakers, stakeholders in the Islamic economy, and the general public in advocating and implementing effective and sustainable women's empowerment.

ŞİŞMAN, Şeyma; MERDAN, Mehmet
Vallis system is a model describing nonlinear interactions of the atmosphere and temperature fluctuations with a strong influence in the equatorial part of the Pacific Ocean. As the model approaches the fractional order from the integer order, numerical simulations for different situations arise. To see the behavior of the simulations, several cases involving integer analysis with different non-integer values of the Vallis systems were applied. In this work, a fractional mathematical model is constructed using the Caputo derivative. The local asymptotic stability of the equilibrium points of the fractional-order model is obtained from the fundamental production number. The chaotic behavior of this system is studied using the Caputo derivative and Lyapunov stability theory. Hopf bifurcation is used to vary the oscillation of the system in steady and unsteady states. In order to perform these numerical simulations, we apply Grünwald–Letnikov tactics with Binomial coefficients to obtain the effects on the non-integer fractional degree and discrete time vallis system and plot the phase diagrams and phase portraits with the help of MATLAB and MAPLE packages.

Günay, Hamdi Furkan
The personal and social benefits and harms of gambling, which has been more accessible, diversified, and widespread thanks to global internet use, sometimes find their place in country agendas. Due to its characteristics, the gambling sector requires effective management through public policies. In this direction, governments determine sectoral policies in two ways: by choosing to ban gambling activities completely or by regulating the sector by legalizing certain types. In this context, taxes stand out as one of the policy tools adopted by many countries. This research aimed to evaluate the success of taxes–as a public policy tool–in controlling the social and economic effects of the gambling industry. Through a systematic review, the role and success of taxation against the social and economic influences of gambling have been evaluated in light of literature research and application examples. The present study revealed that taxes, as a policy tool, are insufficient and may lead to undesirable results in combating gambling, which has limited-positive contributions to the country's economies but harms society by creating severe addictions and other irreversible social costs.

This research investigates the experiences of social work graduates as youth who are not in employment, education, or training (NEET) by employing an intersectional perspective. In-depth interviews were conducted with 21 social work graduates who are unemployed for at least a year. The findings encompass three key themes: being NEET, the reasons for being NEET, and solutions proposed by social work graduates as NEET. The findings evaluate the shared experiences among participants while endeavoring to elucidate how these experiences diverge concerning various social categories. From an intersectional perspective, the results expose disparities in the NEET experience, considering factors such as gender, marital status, being a parent, class, social capital, geographical location, and societal perceptions. The research is expected to contribute to the body of knowledge concerning educated NEETs and the unique strength of it lies in the absence of previous investigations pertaining to NEETs as social work graduates. It is advised that individual and structural factors should be considered in analyzing the experience of being NEET and that micro, meso, and macro social work interventions should be developed in terms of these factors. Furthermore, future research endeavors can focus on evaluating the efficacy of interventions and conducting comprehensive mixed-method studies.

Aktaş, Esra; Atmaca, Hatice Ediz; Akbulut, Hatice Erdoğan
Operating rooms (OR) are one of the most expensive parts of a hospital with complex processes, and the efficient use of resources is of utmost importance. Therefore, proper management and operation of operating rooms are extremely crucial. OR scheduling ensures that the surgeries are performed at the proper time, patients are treated effectively and safely, resources are used effectively, and staff is increased in work efficiency. Furthermore, accurately scheduled surgeries are safer for patients' healing processes. This is dependent on factors such as the availability of qualified personnel at the appropriate time, the readiness of surgical equipment, and the pro-vision of proper sterilization and hygienic conditions. Surgical team scheduling ensures that surgeries begin on time, are completed effectively, and patients are treated safely. It is also critical to reduce employee fatigue and balance the workload. As a result, integrating surgical teams into operating room scheduling problems provides significant benefits. Accordingly, 29 research articles focusing on the problem of OR scheduling, within the scope of constraints on surgical team members, scheduling strategies, uncertainties, and solution methods, are thoroughly re-viewed in this study.

Propolis is a sticky substance produced by bees because of the reaction of beeswax, pollen, and bee enzymes. Particularly, their biological activity and chemical content attract attention. Thus, in this study, the total amount of phenolic and flavonoid substances, Fe3+-Fe2+, Cu2+ (cupric ions reducing activity [CUPRAC]), and Fe3+-TPTZ (ferric ions reducing antioxidant power [FRAP]) reducing, and DPPH• and ABTS•+ scavenging assays in vitro antioxidant properties of propolis samples obtained from four different provinces of Türkiye were determined. In addition, the chemical content of propolis samples was quantitatively determined by LC–MS/MS, and the antiglaucoma property was revealed by hCAII enzyme inhibition. Propolis samples from Ordu presented the highest amounts of total phenolic and flavonoid content (492.3 ± 5.8 and 96.1 ± 2.1, respectively) and also highest antioxidant activity (DPPH• and ABTS•+ IC50 [μg/mL]: 8.884 ± 0.84 and 4.589 ± 0.80, respectively; Fe+3, CUPRAC, and FRAP: 1.051 ± 0.012, 1.021 ± 0.008, and 0.957 ± 0.007 μg/mL, respectively). hCAII enzyme inhibition was highest in Muş propolis (IC50 [μg/mL]: 8.6) as determined. By LC–MS/MS, 53 different components were screened and 35 bioactive components were determined. According to the results, propolis was found to be a raw material because it contains high concentrations of acacetin, chrysin, caffeic acid, and quinic acid (123.824, 24.759, 47.779, and 16.32 mg analyte/g extract, respectively).

Ertekin, Özteki̇N
In this study, without using any uniaxial force and bending moment (N-M) interaction diagrams, designs were carried out on thick columns subjected to uniaxial bending and compression by a novel 1 dimensional (1D) Fuzzy Inverse Logic (FIL) method. For this purpose, firstly, a Fuzzy Logic (FL) model was developed and the FIL method was applied to it thereafter. While, the cross-section width (b), the cross-section height (h), the rebar diameter(f), the numbers of reinforcement rows (Rx and Ry) placed into the cross-section in X and Y directions, the characteristic concrete compressive strength(fck) and the axial force ratio Nr=N/ (b.h.(fck/1.5)) were taken as variable parameters, concrete cover thickness (c), rebar strength (fyd) and k1 parameter defined for the concrete pressure block were kept constant in the developed FL model. After designs were performed on 15 columns having different variable variations by the 1D FIL method, moment bearing capacities of the obtained 9737 alternative designs determined conventionally were compared with the desired moment values. The evaluations made on the comparisons show that the FIL method is not only a very effective artificial intelligence method for the design of reinforced concrete thick columns but also a promising method for many other problems such as control, optimization, design, etc.
