Lök, Şefika İ; Malgaca, Levent; Uyar, Mehmet
This study focuses on active vibration control for a single-link composite box manipulator by using a single actuator for driving and control actions. Model extraction and system identification techniques are studied to obtain mathematical models of the manipulator. The state space model is extracted from the finite element model using modal analysis conducted in ANSYS, while the system identification approach is an experimental modeling method using the input and output signals of the system. The input signals are defined as triangular and trapezoidal motion profiles, while the output signals are the acceleration signals of the manipulator. Proportional derivative and positive position feedback controllers are implemented on the obtained mathematical models to reduce residual vibrations. The simulation results are successfully verified by experiments, and uncontrolled/controlled results are evaluated with reduction rates.

Taşyürek, Zeynep; Kodan, Hülya
Inclusive education is based on the idea that all individuals—regardless of individual characteristics and differences—should have access to education, a fundamental right granted to all. This study examines the relationship between pre-service teachers’ inclusive education awareness and self-efficacy and the impact of different variables that may affect this relationship. For this purpose, the Awareness Scale for Inclusive Education and the Teachers’ Self-Efficacy Perception of Inclusive Education Scale were used as data collection tools. The study was conducted through a correlational survey design to understand the relationship between pre-service teachers’ Awareness of Inclusive Education scores and Teacher’s Self-Efficacy Perception of Inclusive Education scores and determine the regulatory effect of gender and the departments in which the teachers studied on this relationship. The study sample included 360 pre-service teachers who completed the Special Education and Inclusion course. Data were analyzed using SPSS 24.0 and the Process Macro plugin. The results show a significant relationship between pre-service teachers’ awareness of inclusive education and self-efficacy perceptions. Results also indicate that while the regulatory effect of gender on the relationship between pre-service teachers’ inclusive education awareness and self-efficacy perceptions was not significant, the regulatory effect of the department they belonged to was substantial.

Sahin, Huseyin; Kolayli, Sevgi; Kara, Yakup; Can, Zehra; Guler, Halil Ibrahim; Ozkok, Asli; Serdar, Umit
Chestnut (Castanea sativa) blossoms are natural resources that are not put to economic use. They are completely mixed with soil as waste. Thus, this extensive study was designed and remarkable results were found showing the potential usefulness of chestnut blossoms. In addition to the phenolic capacity and antioxidant capacity of the aqueous and ethanolic extracts of dried chestnut flowers, the anti-urease activity of these extracts was studied to demonstrate their therapeutic value. The binding interaction of phenolic substances present in chestnut blossom with urease was shown using molecular docking research. The aqueous extract, with most effect, had total phenolic content of 46.67 ± 0.37 mg GAE/g and total flavonoid content of 6.14 ± 0.40 mg QUE/g. The antioxidant activity was determined by FRAP (648.47 ± 5.27 µmol FeSO4.7H2O/g for aqueous extract and 347.53 ± 2.09 µmol FeSO4.7H2O/g for ethanolic extract) and DPPH (0.05 ± 0.01 mg/mL for SC50 of aqueous extract and 0.11 ± 0.01 mg/mL for SC50 of ethanolic extract) assays, and rutin was found to be the dominant phenolic compound according to HPLC. IC50 values for urease in aqueous and ethanolic extracts were 2.55 ± 0.09 mg/mL and 4.57 ± 0.24 mg/mL, respectively. According to the docking experiments, which were important to support the hypothesis of anti-urease activity, myricetin and luteolin showed different and effective bonding degrees to the target protein when compared with the reference molecule acetohydroxamic acid. In summary, chestnut flowers are rich in phenolic compounds which are responsible for a wide range of biological activities including antioxidant features and urease inhibition. These blossoms could be evaluated as potentially important raw materials for food.

Kök, S.; Türetken, M.S.; Öksüzer, N.; Gökçe, H.S.
This study aims to investigate the radiation shielding efficiency of cement and geopolymer-based mortars after exposure to elevated temperatures which may happen during the activation process of nuclear reactors. To contribute to the shielding properties, these binders were modified with the substitution of colemanite powder (5 and 10%), and barite aggregate was used to be an alternative to silica sand, as well. The produced specimens were exposed to 300 and 500 °C. While the colemanite powder resulted in significant retardation of setting time up to 183% for cement-based series, a set accelerator effect reaching 67% was found in the geopolymer series. Unlike expectation, the losses in mechanical and shielding properties have become more pronounced in geopolymer mortars at the applied temperatures. In particular, a significant increase reaching 28% in compressive strength of cement series was found after 300 °C exposure. It was noted that cement series with reaching a linear attenuation coefficient of 0.162 cm−1 presented more effective shielding against gamma rays when compared to that (0.134 cm−1) of geopolymers. To moderate thermal neutrons, geopolymer series reaching a linear attenuation factor of 2.799 cm−1, were found to be a more promising alternative according to cement series reaching 2.140 cm−1.

Gürefe, Nejla; Güven Akdeniz, Dilşad
The authors examined the knowledge of middle level mathematics teachers instructing in inclusive classrooms to the hearing impairments students (HISs) or learning disabilities students (LDSs). The focus was on teachers’ understanding of students’ misconceptions related to the concept of angles. The study aimed to investigate the teachers’ role in identifying the underlying perceptions of misconceptions among HISs and LDSs as well as their ability to offer effective solutions. The mathematics teachers responsible for HISs and LDSs were the subjects of this cross-case study, with the unit of analysis being teachers’ knowledge of misconceptions concerning the concept of angles. Face-to-face interviews were employed to collect data, and subsequent analysis utilized a cross-case approach. The study findings revealed that both groups of teachers encountered numerous misconceptions for the first time. While teachers of HIS (HIST) identified the source of misconceptions as either teachers or students, teachers of LDS (LDST) more frequently attributed misconceptions to teachers and employed various representations to address and dispel these misconceptions. The authors recommended that teachers develop deep understanding of their students and identify potential misconceptions and that they explore diverse methods for taking precautions to prevent misconceptions.

Özdemir, Akın; Uçurum, Metin
Several micro-particle-size additives and filler minerals are added to many industrial products, especially plastic, in order to reduce cost and improve mechanical properties and appearance. Also, grinding and surface modification are two fundamental properties of the filler minerals used in plastic products. Notably, Bayburt stone (BS) used as a natural raw material from Bayburt, Türkiye contains 76% SiO2 and 15% Al2O3. In this paper, the hydrophilic surface structure of micronized Bayburt stone (MBS) was made hydrophobe by mechanochemical surface modification using calcium stearate [Ca(C17H35COO)2] in a laboratory-type planetary mill. Next, the optimum conditions of the surface modification design factors, which are (1) ball filling ratio = 30.53%, (2) powder filling ratio = 10.43%, (3) mill speed = 475.91 rpm, (4) chemical dosage = 1.99% of powder, and (5) modification time = 4.83 min., were obtained using the proposed I-optimal design-focused optimization model when predicting the model parameters. In addition, a coated micronized Bayburt stone (CMBS) product with an active ratio (AR) of 99.90% and d10, d50, and d90 values of 1.32 μm, 3.48 μm and 9.55 μm were achieved. Finally, particle size distribution (PSD), thermo-gravimetric and differential thermal analyzer (TG-DTA), Fourier transform infrared (FTIR), scanning electron microscope (SEM), electron dispersive spectrum (EDS), and contact angle analyses were performed on the CMBS product.

Caliskan, Berrak; Sayan, Enes; Igman, Erdal
This study investigates the synthesis and characterization of rare earth elements (REEs) doped TiO₂ thin films based photoanodes for use in dye-sensitized solar cells (DSSCs). For this purpose, TiO₂ films were doped with Ho³⁺, La³⁺, Er³⁺, and Yb³⁺ ions to enhance photoelectrochemical properties. Characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis spectroscopy, BET surface area analysis, and X-ray photoelectron spectroscopy (XPS) were employed for the structural, morphological, and optical characterization of the synthesized photoanodes and CEs. REEs doping improved the surface morphology and optical properties of TiO₂, in particular, it increased photon absorption in the visible light range. La³⁺ and Ho³⁺ significantly improved photovoltaic performance, achieving power conversion efficiencies of 3.78% and 2.87%, respectively, compared to that of pure TiO₂. These enhancements indicate improved charge transport and light harvesting due to incorporation of REEs. Additionally, replacing the conventional platinum counter electrode (CE) with reduced graphene oxide (rGO) further enhanced performance, offering a low-cost and efficient alternative. The study highlights the combined benefits of REEs doping and rGO integration in improving DSSCs efficiency. These findings contribute to the development of more sustainable, cost-effective solar energy technologies and underline the potential of REEs-doped TiO₂ films and rGO electrodes in advancing next-generation photovoltaic devices.

Erbayrak, Engin; Eker, Beril; Colak, Murat
This study primarily examines the strength of a single lap joint having a mixed adhesive overlap consisting of a single adhesive and its thermoplastic reinforced state under varying temperatures. In the single lap joint, Titanium-Boron reinforced A356 aluminum was employed as the metal adherend, while plain woven glass fiber-reinforced epoxy (GFRE) was employed as the composite adherend. In the application of the mixed adhesive overlap, the brittle adhesives were employed in the middle section of the lap joint, while the reinforcement of the thermoplastics was employed on the adhesives at both sides of the lap joint. The single lap joints were subjected to tensile tests at 1 mm/min loading rates under room temperature and 120 °C, which is the melting point of the copolyester. In the numerical analysis, the cohesive zone model was applied in order to define the adhesives; however, elastic isotropic and orthotropic material behaviors were employed for the metal and composite adherends, respectively. Eventually, it is determined that the strength of a mixed adhesive lap joint consisting of a single adhesive and its thermoplastic reinforced state is better than a lap joint made with the mono-adhesive alone. Although literature suggests that mixed adhesive overlaps can be formed using at least two different adhesives (one ductile and one brittle), this study demonstrated that a mixed adhesive zone can be created using a single adhesive and thermoplastic reinforcement.

Ersöz, G.; Kan, M.E.; Yenilmez, M. Ince; Kantar, G.
In recent years, research on elite sport policies has mainly focused on systems in Europe, North America and Australia. This study represents the first qualitative analysis of Turkey within the framework of the SPLISS model, aiming to fill the regional gap in the literature and offer original contributions regarding the model’s cultural and structural adaptability. In this context, the study aims to analyse the policy factors affecting international sporting success in Turkey. A total of 15 individuals–five athletes, five coaches and five sports managers–aged between 21 and 51 and actively involved in sport, participated in the study. A semi-structured interview technique was used, with questions prepared from the SPLISS model perspective, and the data were analysed using content analysis. The findings reveal that financial support for sport in Turkey is inadequate, there is no merit-based system in sports governance, the limited hours and content of physical education classes in schools reduce participation in sport, career support for athletes is insufficient, talent identification projects are dysfunctional, coach education has significant shortcomings and there is a lack of collaboration between sport science researchers and practitioners. The study indicates that Turkey’s sports policies require comprehensive restructuring through reforms in several areas, including equitable financial support, merit-based governance, enhanced collaboration and coordination among sport institutions, long-term strategic planning, strengthening school-based sport, sustainable career support for athletes and fostering stronger cooperation between researchers and practitioners in sport sciences.

Öztürk, Ufuk Kemal; Abderrahmane, Babe Cheikh; Uzun, Oğuzhan; Abdioğlu, Murat; Güner, Sait Barış; Quéval, Loïc
This study introduces a novel Top-Interior Multi-Seeding Melt Growth (TI-MSMG) technique for fabricating high-performance YBCO bulk superconductors and explanations some physical background based on FEM modelling. The depth of the interior seed was gradually changed as 0, 2 and 4 mm (samples S0, S2 and S4, respectively) from the upper surface of the samples. By incorporating an interior seed into the precursor pellet, the TI-MSMG method enables systematic control over grain morphology and critical current density distribution. Magnetic levitation and guidance forces were measured using a three-axis force measurement system, and a two-dimensional finite element method (FEM) model based on the H-formulation of Maxwell’s equations was developed to simulate the electromagnetic behaviour of the superconductors with different seed positions. Experimental and modelling results reveal that samples incorporating an interior seed (S2) exhibit significantly enhanced levitation and guidance forces compared to S0 and S4, attributable to improved inter-domain interactions and morphological consistency, so a better current coupling. The numerical simulations accurately reproduced the experimental findings, confirming the validity of the modelling approach. These findings indicate that the TI-MSMG process not only addresses some limitations of conventional top-seeding methods but also enhances levitation force performance through optimization of interior seed depth, thereby enabling more efficient and tailored designs for high-temperature superconducting systems such as magnetic levitation, energy storage, and superconducting motors.

Kizil, Seda; Demir, Rahime Nur
In healthcare institutions, employees who experience a strong alignment between their personal values and those of the organization are more likely to demonstrate organizational citizenship behaviors, which in turn contribute to enhanced job performance. The primary purpose of this study is to investigate the mediating role of organizational citizenship behaviors in the relationship between person–organization fit and job performance. The research population consists of 530 employees working at Bayburt State Hospital, Türkiye as of 2023, and the sample includes 342 participants. The analysis results indicate that organizational citizenship behaviors have a direct and positive effect on job performance. Furthermore, the compatibility between the individual and the organization significantly and positively influences organizational citizenship behaviors. In addition, organizational citizenship behaviors are found to have a significant and positive impact on job performance. These findings highlight the important role that organizational citizenship behaviors play in enhancing employee performance. The results also reveal that organizational citizenship behaviors serve as a key mediating variable in the relationship between person–organization fit and job performance. This study provides important insights for the development of employee management and performance improvement strategies in the healthcare sector. In particular, efforts to strengthen the alignment between employees and the organization may foster higher levels of organizational citizenship behaviors, which can, in turn, positively influence job performance. Implementing strategies that support person–organization compatibility and encourage organizational citizenship behaviors can effectively enhance both employee satisfaction and the overall performance of healthcare institutions. Such strategies are essential for achieving long-term success in the healthcare industry.
- MakaleAçık Erişim2025Scopus SJRQ1The Effect of Self-Regulation on the Need for Psychological Help Through Happiness, Resilience, Problem Solving, Self-Efficacy, and Adjustment: A Parallel Mediation Study in Adolescent Groups
Akeren, İhsan; Çelik, Eyüp; Yayla, İbrahim Erdoğan; Özgöl, Mustafa
Introduction: Adolescence is a developmental period in which the risk of mental problems is high. Failure to resolve the problems encountered during this period may result in the need for psychological help. Based on the literature review, this study aimed to examine self-regulation, which has the potential to reduce adolescents’ need for psychological help, and the mediation of happiness, resilience, problem solving, self-efficacy, and adjustment through this skill. Methods: In the cross-sectional correlational survey design study, 1013 adolescents (542 girls, 471 boys, mean age: 15.04 ± 1.75 years) aged 12–19 years and studying in middle and high school in Bayburt, Turkey were reached. Seven different questionnaires, valid and reliable in adolescent groups, were used to measure the study variables. Results: Correlation results showed that all predictors were positively correlated with each other and negatively correlated with the dependent variable, the need for psychological help. After testing the assumptions, the results of the parallel mediation analysis showed that happiness, problem solving, self-efficacy, and adjustment fully mediated the effect of self-regulation on the need for psychological help. Another finding is that resilience is not a predictor of psychological distress. Conclusions: The results are important because they provide insight for those working in the field of adolescent mental health in terms of understanding the factors through which self-regulation reduces the need for psychological help.

For the special amine 7-Amino-3-(4-aminophenyl)-5H-thiazolo[3,2-a]pyrimidin-5-one (AHTPO), previously reported experimental biological activities served as the foundation for further studies. Computational chemistry and molecular simulation techniques were subsequently applied to investigate AHTPO. Its interactions with trypsin enzymes derived from cold-adapted fish species were examined. The compound's biological activity and pharmacokinetic properties were assessed using DFT calculations, molecular docking, and ADME analyses. Molecular docking results indicated that AHTPO exhibits strong binding affinities with the 1A0J and 2TBS enzymes, with the binding to 2TBS being energetically more favorable. Additionally, ADME analysis revealed that while the AHTPO shows potential for pharmaceutical applications, its gastrointestinal absorption and blood-brain barrier permeability may present certain limitations. Regarding its electronic and optical properties, AHTPO's high dipole moment and polarizability values enhance its flexibility and adaptability in biological environments. The HOMO-LUMO energy gap suggests that the AHTPO achieves a balance between stability and reactivity, enabling high activity in biomolecular interactions. These findings highlight the promising pharmacological potential of AHTPO in binding with trypsin enzymes, suggesting its viability as a therapeutic agent.

Kaya, Yasemin; İspirli, Hümeyra; Bozkurt, Fatih; Sağdıç, Osman; Şengül, Mustafa; Dertli, Enes
BACKGROUND: One of the major contributors to postharvest losses in tomatoes is the development of infectious mold diseases. In this study, four distinct biodegradable film formulations were developed incorporating postbiotics derived from Lactiplantibacillus plantarum Y48 and the polysaccharide alternan. The formulations included alternan, sodium alginate and glycerol (AAG), alternan, postbiotic, sodium alginate and glycerol (APAG), postbiotic, sodium alginate and glycerol (PAG), and sodium alginate and glycerol (AG) as a control. The films were characterized in terms of their physical, mechanical, thermal, and morphological properties. To assess antifungal efficacy, tomatoes artificially inoculated with Alternaria alternata were coated with each film and stored at ambient temperature for 8 days. RESULTS: The incorporation of alternan and postbiotics enhanced both the mechanical strength and thermal stability of the films. Fourier-transform infrared (FTIR) analysis confirmed the successful integration of the bioactive components into the polymer matrix. Scanning electron microscopy (SEM) imaging revealed that postbiotic addition contributed to a rougher and more rigid surface morphology, while alternan improved the structural cohesion of the films. All film formulations exhibited significant inhibitory effects against A. alternata, with the PAG formulation demonstrating the most pronounced antifungal activity. CONCLUSION: These results suggest that the PAG film, enriched with postbiotics, represents a promising biocontrol strategy for mitigating fungal spoilage in tomatoes. In conclusion, this study underscores the potential of combining postbiotics and alternan for the development of active, biodegradable edible films with antifungal functionality for postharvest preservation.

Çinici, Murat
Spiritual counseling has expanded rapidly in Turkiye over the past two decades. Hospitals, prisons, family guidance offices, eldercare facilities, disaster-response systems, and addiction recovery programs now host spiritual counselors as part of routine care. The methodological foundation of these services, however, remains underdeveloped. Using a conceptual review and theoretical integration approach, this article proposes—but does not empirically test—a framework that links spiritual counseling practice in Turkiye to the Intention Code Model (NIKOM), a recently formulated cognitive model that conceptualizes mental life through if–then schemas (codes), their activation, and their alignment with bodily systems. The article reviews the institutional landscape of spiritual counseling in Turkiye, situates NIKOM among adjacent cognitive models, and shows how core Islamic concepts—tawakkul, ṣabr, shukr, tawba, and dhikr—can be interpreted as functions relevant to counseling practice. A standardized five-stage intervention template is proposed and applied to six service domains. The article closes by offering five testable propositions, considering ethical limits, and articulating concrete referral criteria. The proposed framework is theoretically grounded and empirically testable; clinical efficacy is not claimed.

Background: Most people use hair dye to change their hair color. The aim of this study was to investigate how hair dye affects rat behavioral tests. Methods: This study examines the effects of hair dye exposure on the Three-Chambered Sociability, open field, elevated plus maze and novel object recognition tests. Group 1 (n=8) was dyed twice, Group 2 (n=8) was dyed four times, Group 3 (n=8) was dyed eight times and Group 4 (n=8) was water-treated and dried eight times. Result: The control group (Group 4) sniffed certain objects more in the first occupied cage. The groups exposed to less dye explored for longer periods (p<0.05 higher in Groups 1 and 2 than in the control group). In the open field test, Group 2 showed more scratching, hunger and urination. The control group showed more cage interaction than the other groups (p<0.05). In the elevated plus maze test, no difference in time was found between the groups. In conclusion, hair dye chemicals may affect rat behavior, but neurotoxicity and oxidative stress tests are required to confirm this.
