Öğe Interleukin-34 as a Robust Predictor of No-Reflow Phenomenon in ST-Elevation Myocardial Infarction: Insights into Inflammatory Mechanisms and Clinical Implications(Galenos Publ House, 2024) Karasu, Mehdi; Bolayir, Hasan Ata; Aktas, IbrahimObjective: ST-elevation myocardial infarction (STEMI) poses a significant challenge despite advances in reperfusion strategies. The no-reflow phenomenon, characterized by inadequate microvascular blood flow restoration following successful revascularization, remains poorly understood. Inflammation, particularly interleukin-34 (IL-34), is implicated in cardiovascular disease, prompting investigation into its role in no-reflow. Methods: This observational study included 182 patients with STEMI (32 with no-reflow, 150 without) and 100 controls. Clinical and angiographic data were analyzed, and IL-34 levels were measured. Logistic regression and receiver operating characteristic (ROC) analysis assessed IL-34's predictive value for no-reflow. Results: Patients with no reflow exhibited elevated IL-34 levels compared with controls and those without no-reflow. Logistic regression identified IL-34 as an independent predictor of no-reflow (odds ratio: 1,020, p<0.001). ROC analysis showed IL-34's significant predictive value (area under the curve: 0.972, p<0.001). Conclusion: IL-34 emerges as a robust predictor of no-reflow in STEMI, potentially reflecting its role in macrophage activation and the inflammatory response. These findings suggest a novel avenue for understanding and mitigating no-reflow in STEMI, paving the way for targeted therapies. Early identification of high-risk patients could inform tailored interventions, ultimately improving STEMI outcomes. Further research is warranted to elucidate IL-34's mechanistic involvement and validate its predictive value in larger cohorts.Öğe Transtrochanteric vs. posterolateral approaches in hemiarthroplasty after proximal femoral nail complications: A comparative study(Turkish Assoc Trauma Emergency Surgery, 2025) Gokalp, Oguzhan; Ari, BunyaminBACKGROUND: Proximal femoral nailing is a widely used technique for treating intertrochanteric femur fractures but may result in complications requiring revision surgery. Hemiarthroplasty is a common solution, with the transtrochanteric and posterolateral approaches being two surgical options. This study aimed to compare these approaches in terms of surgical outcomes and complication rates. METHODS: A retrospective analysis was conducted on 79 patients who underwent revision hemiarthroplasty for complications related to proximal femoral nailing between 2019 and 2022. Patients were divided into two groups based on the surgical approach: transtrochanteric (Group 1, n=36) and posterolateral (Group 2, n=43). Key variables included surgical time, intraoperative blood loss, transfusion requirements, functional outcomes (Harris Hip Score), and complication rates. Statistical significance was set at p<0.05. RESULTS: Group 1 had a shorter surgical time (49.6 +/- 5.69 vs. 64.8 +/- 10.29 minutes; p<0.001) and lower intraoperative blood loss (395.8 +/- 142.89 vs. 474.2 +/- 130.94 mL; p=0.004) compared to Group 2. Transfusion requirements were also lower in Group 1 (0.4 +/- 0.71 vs. 1.2 +/- 1.014 units; p=0.002). Harris Hip Scores were similar between groups (74.7 +/- 7.17 vs. 72.4 +/- 7.8; p=0.276). Although overall complication rates did not differ significantly (p=0.744), dislocations occurred only in Group 2 (6.5%, n=2). CONCLUSION: The findings suggest that the transtrochanteric approach may offer advantages in surgical efficiency and reduced intraoperative challenges. However, both techniques yielded similar functional outcomes and overall complication rates. Further studies are necessary to validate these findings and assess their applicability in varied clinical contexts.Öğe Some classifications for Gauss map of Tubular hypersurfaces in E41 concerning linearized operators Gk(Hacettepe Univ, Fac Sci, 2025) Kazan, Ahmet; Altin, Mustafa; Turgay, Nurettin CenkIn this study, we deal with the Lauss map of tubular hypersurfaces in 4-dimensional Lorentz-Minkowski space concerninL the linearized operators L-1 (ChenL-Yau) and L-2.

Studies have shown that very low and very high temperatures reduce engine efficiency and significantly increase energy consumption, while affecting regenerative energy recovery. Therefore, in the presented study, the effects of outdoor temperature on range and energy consumption were investigated using real-time big data obtained from Electric Buses (EO). The field application of the study was carried out with 22 24.7-meter EOs. The EO route was divided into 4 different regions and the energy consumption for each region and the analysis of the outdoor temperature corresponding to this consumption were obtained using regression techniques. First, the energy consumption model was created and the driving cycle was calculated for each region. Then, the driving cycle for the entire route was created and the energy consumption on the route was expressed as a mathematical model. Trilayered Neural Network (TNN) gave the best result in the calculations of the entire route. Finally, the mathematical model obtained as a result of TNN was reconsidered using the SeaHorse optimization method. Considering the analysis for the entire route (R), it was calculated that the most efficient consumption is 3.02 kWh/km and this consumption value can be achieved with a temperature of 21.5oC. This study has become a reference study for other electric vehicle manufacturers in determining the range of their vehicles in different climate conditions.Öğe Effect of Maize and Soybean Mixtures on Microorganism Dynamic, Fermentation Profile and Quality of Silage Feed(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2026) Kilic, Fatma Akbay; Gunaydin, Tugba; Kizilsimsek, MustafaThis study investigates the effects of different mixture ratios of maize and soybean on the fermentation profile and nutritional quality of silage under Eastern Mediterranean conditions, as well as the relationship between silage parameters. The 5 mixture rates (100M:0S, 75M:25S, 50M:50S, 25M:75S, and 0M:100S) of Maize (M) and Soybean (S) were prepared for ensiling. After 60 days of fermentation, silages were opened and analyzed for fermentation profile and other quality characteristics. The results showed that increasing the maize proportion in silage led to an increase in lactic acid (LA) and a decrease in pH level. Propionic acid and acetic acid content were higher in sole soybean and 25M:75S silage than in sole maize silage and other mixture rations. Maize silage had considerably higher water-soluble carbohydrate (WSC) content than soybean silage, while soybean had significantly higher protein content than that of maize. Maize-soybean mixture increased crude protein content and reduced neutral detergent fibre (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) content in silage compared to sole crop maize silage. The silage quality of maize+soybean mixture can be improved with inclusion levels of soybean from 25% to 50%.Öğe Effects of Altitude on Pomological Traits, Bioactive Composition, and Antioxidant Capacity of 'Cataloglu' Apricot Cultivar(Univ Namik Kemal, 2026) Kutsal, Ibrahim KutalmisAltitude exerts a decisive influence on the physicochemical and functional attributes of apricots, yet its effects on the traditional Malatya dried apricot cultivar 'Cataloglu' remain less studied. In this study, fruits harvested in 2024 from commercial orchards in low-altitude Battalgazi (similar to 730 m) and high-altitude Darende (similar to 1150 m) were compared in terms of pomological traits, bioactive composition, and antioxidant capacity. Fruits grown at high altitude had greater fruit length, flesh firmness of 6.32 kg cm(-2), titratable acidity, soluble solids content of 24.12%, and higher a* redness values, whereas no altitude-related differences were found in some size and other color parameters (L* and b*). Flesh firmness at low altitude was 6.00 kg cm(-2) and soluble solids content was 22.49%. Bioactive analysis showed that total phenolic content reached 784.14 mu g GAE g(-1) FW at high altitude compared to 481.60 mu g GAE g(-1) FW at low altitude. Similarly, DPPH and ABTS antioxidant activities were higher at high altitude, measuring 15.31 and 2.94 mu mol TE g(-1) FW, respectively, versus 8.51 and 1.24 mu mol TE g(-1) FW at low altitude. In contrast, total carotenoid content was higher at low altitude with 8.15 mu g beta-carotene g(-1) FW, while high-altitude fruits contained 6.08 mu g beta-carotene g(-1) FW. These contrasting tendencies reflect altitude-driven microclimatic differences: cooler temperatures in uplands stimulate phenolic accumulation, whereas warmer lowland conditions promote carotenoid biosynthesis. The findings highlight a clear quality balance. High-altitude fruits stand out for their antioxidant potential and functional health value, whereas low-altitude fruits are notable for their higher carotenoid content and bright yellow-orange color. These results can guide cultivar and site selection according to market demands and consumer preferences. With its relative tolerance to spring frost and drought, 'Cataloglu' could see increased cultivation in high-altitude orchards under future climate change scenarios.Öğe Turkish Validityand ReliabilityStudyofthe Negative Menstrual Attitudes Assessment Scale: A methodological study(Marmara Univ, Inst Health Sciences, 2025) Ozsahin, Zeliha; Santur, Sinem Guven; Derya, Yesim AksoyObjective: The objective of this study is to determine the validity and reliability of the Negative Menstrual Attitudes Assessment Scale (NMAS) in T & uuml;rkiye. The NMAS is a scale that evaluates women's negative attitudes towards menstruation.. Methods: This study employed a methodological approach and concentrated on female students registered in the Faculty of Health Sciences at a public institution from June to August 2023. The scale underwent a three-phase Turkish adaption procedure, comprising linguistic validity, content validity, and a pilot implementation. The pilot research had a cohort of 30 individuals. Following this, construct validity was assessed using Kaiser-Meyer-Olkin, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). Furthermore, assessments were performed to evaluate reliability, encompassing Cronbach's alpha internal consistency coefficient, item-total correlation, test-retest analysis, and ROC analysis for determining cut-off scores. Results: According to the EFA analysis, which confirmed the validity of the 15-item scale, it was determined that no items had factor loadings below 0.30. The subsequent CFA analysis validated the three-factor structure of the NMAS, exhibiting good fit indices. The resultant 15-item scale consists of three sub-dimensions: Debilitating Event, Bothersome Event, and Natural Event. The internal consistency coefficient of NMAS, as determined by Cronbach's alpha, was 0.861, 0.855, 0.784, and 0.772 forthe overall measure and its sub-dimensions, respectively. Moreover, the item-total correlation and test-retest analysis of the scale demonstrate a robust association. Conclusion: A rigorous and accurate instrument has been created to evaluate unfavorable menstruation attitudes among women in Turkish culture. The scale demonstrated robust psychometric properties, confirming its validity and reliability for assessing negative menstrual attitudes in Turkish culture.Öğe Comparison of asprosin immunoreactivity in endometrial hyperplasia and grade-1 endometrial adenocarcinoma: A retrospective case-control study(Galenos Publ House, 2025) Senocak, Ahmet; Yavuzkir, Seyda; Atilgan, Remzi; Yurt, Nurdan; Balta, Hilal; Kuloglu, Tuncay; Cim, BunyaminObjective: It has been demonstrated that asprosin, a glucogenic adipokine released by white adipose tissue, contributes to the pathophysiology of cancer and disorders associated with it. The aim of this study was to compare the immunoreactivity of asprosin in grade I endometrial adenocarcinoma and in endometrial hyperplasia (EH) with and without atypia. Materials and Methods: A total of 80 cases previously diagnosed with grade 1 endometrial adenocarcinoma and EH with and without atypia, and for which paraffin blocks were obtained, were included in the study. The resulting paraffin blocks were sectioned again and immunostained for asprosin. A total of 80 cases were divided into 4 groups according to their histopathological diagnoses. Group (G) 1 (n=20): proliferative endometrium, G2 (n=20): EH without atypia, G3 (n=20): EH with atypia, G4 (n=20): Grade 1 endometrial adenocarcinoma. Endometrial samples from 80 patients were sectioned, and asprosin immunoreactivity was evaluated by immunohistochemical staining under a light microscope. Results: In comparison to the proliferative endometrium group, the grade I endometrial adenocarcinoma group had considerably increased asprosin immunoreactivity. However, between the proliferative endometrium group and the groups with endometrial hyperplasia, without atypia, and endometrial hyperplasia, with atypia, there was no significant difference in asprosin immunoreactivity. Conclusion: While asprosin immunoreactivity scores are higher in grade I endometrial adenocarcinomas, they are similar to those of the proliferative endometrium in cases of EH with and without atypia, suggesting that energy metabolism contributes to the development of cancer arising from endometrial hyperplasia. Asprosin immunoreactivity can be studied as a marker to predict the progression of EH to cancer.Öğe A Multimodular AI Algorithm for Automated Assessment of Left Ventricular Function in Ischemic Heart Disease: Ejection Fraction, Wall Motion, and Regional Myocardial Segmentation(Galenos Publ House, 2026) Gul, Sidem; Tasdemir, Resit; Acikgoz, Beyza; Duman, Hakan; Hodzic, Hamza; Koker, Sena; Kivrak, MehmetBackground: Ischemic heart damage reduces the pumping efficiency of the heart by affecting the left ventricular ejection fraction (LVEF) and causing wall motion abnormality (WMA). In daily clinical practice, these parameters are interpreted by physicians using two dimensional transthoracic echocardiography (2D-TTE). Because 2D-TTE reports rely on visual evaluations, they are subject to experience-based limitations and exhibit low reproducibility. Aims: To develop an artificial intelligence algorithm composed of two modules that enable automatic LVEF calculation and WMA detection for analyzing 2D-TTE images. Study Design: Diagnostic accuracy study. Methods: A total of 600 adult patients were retrospectively included. The model combined static frame segmentation with dynamic tracking using a hybrid Simpson's method applied to apical 2-and 4-chamber views. Model performance was assessed against cardiologist measurements using Bland-Altman analysis. The YOLOv8 and ResNet50 models were employed for the wall motion module. Performance metrics, including accuracy, precision, F1 score, and area under the curve, were evaluated. Results: In the Bland-Altman analysis, the mean bias between the LVEF module and cardiologist measurements was-4, with limits of agreement ranging from-15 to-3. Regression analysis demonstrated a strong correlation between the LVEF module and cardiologist measurements (r = 0.71, p < 0.001). In the wall motion module, the YOLOv8 segmentation model exhibited high accuracy, while ResNet50 achieved superior performance with an accuracy of 95%. The algorithm's color coding contributed to standardized interpretation among operators, enhancing consistency. Conclusion: This is the first study to integrate automated EF calculation and WMA detection within a single workflow. SafeHeart offers accurate, reproducible, and rapid analysis, with the potential to support routine echocardiography practice. Color-coded region segmentation can facilitate more standardized and reliable results.Öğe Determination of cortisol concentrations using different biomarkers in dairy goats during pregnancy(Tubitak Scientific & Technological Research Council Turkey, 2026) Guven, Fatma Mira; Pehlivan, ErkanPregnancy is considered one of the most physiologically stressful periods in mammals. In the present study, serum and hair cortisol concentrations were measured in nine female Akke & ccedil;i goats, including five primiparous (1.5 years old) and four multiparous (3.5 years old), to evaluate chronic stress during pregnancy. Hair samples were collected in October, November, and December following the introduction of bucks to the herd and within the first 12 h postpartum (corresponding to the 1st, 2nd, 3rd, and 7th sampling times). Hair samples were not collected in January, February, or March (the 4th, 5th, and 6th sampling times) due to insufficient hair growth. Blood samples were obtained monthly between October and March during pregnancy and within the first 12 h postpartum. Both blood and hair samples were processed for hormone analysis in the laboratory. Cortisol concentrations in all samples were determined by enzyme immunoassay. The statistical analysis revealed no significant differences in serum cortisol concentrations between the sampling times or parity groups, whereas significant differences were observed only in hair cortisol concentrations among period means in the hair matrix (p < 0.01). Therefore, it was concluded that hair cortisol concentrations during pregnancy in Akke & ccedil;i goats represent a more reliable biomarker of long-term stress compared with serum cortisol concentrations.Öğe Renewable energy production in Artvin Çoruh University ANG Botanical Garden: Potential, application and challenges(Pamukkale Univ, 2025) Keskin, Adalet; Yazar, Elanur Adar; Dogansahin, KadirThis study evaluates the capability of renewable energy sources (wind, solar and biomass) to meet the energy needs of Artvin Coruh University Ali Nihat Gokyigit Botanical Garden. As a result of the study, it has been determined that the wind speed in the region is insufficient for electricity generation from wind energy, as 0.0845 kW/h. In the analyses performed on the PVsol environment for the potential of a PV system, it has been concluded that 256.9 MWh of energy could be generated annually. The economic analyses resulted in the payback period of the PV system being calculated as 8.8 years. It was also suggested that the annual average of 3500-5000 kg of pruning waste could be utilised by elemental analysis and incineration or used for biogas production by anaerobic digestion together with food waste (27 tonnes/year). The study aims to raise awareness for on-site energy production by using local resources and thus reducing energy costs.Öğe Effects of storage temperatures on quality and phytochemical properties of the hawthorn (Crataegus azarolus L.) during storage and shelf life(Tubitak Scientific & Technological Research Council Turkey, 2025) Ozdemir, Ahmet Erhan; Caliskan, Oguzhan; Bayazit, Safder; Gunduz, Kazim; Gunes, Nurdan Tuna; Karasahin, Zafer; Karahan, Ramazan BestamiThis study aimed to investigate the effects of storage temperature on the quality and phytochemical characteristics in Sultan hawthorn cultivar during cold storage and shelf life. Fruits were stored at 0 +/- 0.5 degrees C and 4 +/- 0.5 degrees C and 90 +/- 5% relative humidity (RH) for 6 months in cold storage and were analyzed every month. In addition, hawthorn fruits were kept at 20 +/- 0.5 degrees C and 75 +/- 5% RH for 7 days, and their shelf life was investigated at monthly intervals. Weight loss, appearance, the incidence of physiological disorders and fungal decay, fruit skin color, firmness, total soluble solids (TSS) content, titratable acidity (TA), TSS/TA ratio, pH, sensory evaluation, vitamin C, sugar profile (glucose, fructose, and sucrose), total antioxidant scavenging capacity, total phenolics, total flavonoids, and total anthocyanins were determined during storage and shelf life. According to the results, firmness was the most prominent criterion in determining the harvest time. The second week of September was determined as the optimum harvest time for the Sultan hawthorn cultivar. Weight loss during storage was higher at 4 degrees C (14.34%) compared to 0 degrees C (9.07%). The results showed that this cultivar can retain most of the fruit quality and phytochemical attributes when stored at 4 degrees C and 85-90% RH for 3 months, and 0 degrees C and 85-90% RH for 4 months. Further studies are required to expand our knowledge of sophisticated techniques to maintain the fruit quality of hawthorn during long-term storage.Öğe Operational Movement Strategies of Volunteer Search and Rescue Teams: February 6, 2023 Kahramanmaras Earthquakes Experience(Afet ve Acil Durum Yonetimi Baskanligi (AFAD), 2025) Kocer, Musab Suleyman; Demirbilek, OmerDisasters are sudden and devastating events that require effective search and rescue (SAR) activities to reduce loss of life and property. This study examines the factors influencing volunteer SAR teams’ decisions to stay, relocate, or withdraw from operational areas during the 2023 Kahramanmaraş earthquakes. Using a phenomenological design, semi-structured interviews were conducted with 13 team leaders from seven NGOs, and the data were thematically analyzed. Findings indicate that these decisions are shaped not only by operational needs but also by psychological factors, organizational structure, team dynamics, and environmental threats. The study contributes to understanding volunteer decision-making, strengthening coordination, and enhancing professionalization in disaster volunteerism. © (2025), (Afet ve Acil Durum Yonetimi Baskanligi (AFAD)).

This study compared anthropometric measurements and skinfold thickness (SFT) between individuals with PE and ED to examine associations with regional fat distribution. A total of 90 men aged 20–50 years participated and were divided into three groups: ED (n = 29), PE (n = 28), and control (n = 33). Ethical approval and informed consent were obtained. SFT was measured at seven anatomical sites: triceps, biceps, subscapular, suprailiac, abdominal, thigh, and chest. SFT values in the triceps, biceps, suprailiac, subscapular, and thigh were significantly higher in both ED and PE groups than in controls (p < 0.05). The PE group showed significantly greater abdominal SFT than both the ED and control groups (p < 0.05). Although chest measurements did not differ significantly, this region showed the most consistent correlations across groups. Overall, individuals with ED and PE exhibited higher regional fat accumulation than healthy controls, with abdominal fat being particularly elevated in PE. These findings highlight the potential role of regional fat, particularly abdominal fat, in the clinical evaluation of sexual dysfunctions. SFT-based assessments may serve as practical tools for identifying and managing PE and ED. © 2026 The Author(s).Öğe Evaluation of Use Cases of İzmir Folk Songs in Fine Arts High School Baglama Books(T.C.

Tolerance is one of the most important strategies for plants in coping with cold stress. However, the tolerance depends on the plant organ and the phenological phase of the trees. Even though the tree trunk, the main branches and the flower buds are usually tolerant to even extremely low temperatures at dormancy period, flower buds can be damaged abnormally by low temperatures especially when the low temperatures occur after a warm period and/or when the temperatures are extremely low. In these cases, most of the flower buds can be damaged and anomalies may also occur in flowers that remain alive. In this study, the flower bud injuries and the flower structures were investigated in such a case occurred in in Kuluncak district of Malatya province in Türkiye in 2020-2021 winter season. The temperature was below-20°C for several times and mostly after a warm period. In order to investigate the impact of the related frosts on apricot trees, this study was carried out in 32 apricot orchards (9 for ‘Hacıhaliloğlu’ cultivar and 23 for ‘Kabaaşı’ cultivar) located in the area. The results showed that the injury rate in the ‘Hacıhaliloğlu’ orchards was between 94 and 100 %, while, it varied between 22 and 87 % in the ‘Kabaaşı’ orchards. In the surviving buds; petal, stamen and pistil were significantly shorter in both of the cultivars. The study clearly showed how serious winter frost damage can be and that necessary precautions must be taken especially when establishing orchards in the areas where winter frosts are prevalent. © 2025, Centenary University.

Identifying protective factors against psychological symptoms is therefore essential. This study examined, among university students living in a city severely affected by the February 6 earthquakes in Türkiye, the mediating role of difficulties in emotion regulation in the relationship between perceived stress and psychological symptoms, and the moderating role of spiritual well-being between emotion regulation difficulties and psychological symptoms. The research employed a quantitative, cross-sectional, relational survey design with 513 participants (212 males, 301 females) aged 17–62 years. Data were gathered through the Personal Information Form, the Perceived Stress Scale (PSS-14), the Difficulties in Emotion Regulation Scale–Short Form (DERS-SF), the Three-Factor Spiritual Well-Being Scale (SWBS), and the Brief Symptom Inventory (BSI). Analyses were conducted using SPSS 20.0. Normality assumptions were tested, and Pearson correlation analysis was applied to explore the direction and strength of relationships. Mediation and moderation analyses were performed with Hayes’ PROCESS macro (version 4.2). Findings revealed a significant negative correlation between perceived stress and spiritual well-being (r(511) = −.41, p < .01). not reported. However, testing the main hypothesis (H7) using Model 14 showed that the interaction between spiritual well-being and difficulties in emotion regulation was not significant. This suggests that, although spiritual well-being is often described as a protective factor, its impact may operate more directly on psychological symptoms rather than moderating the link between emotion regulation difficulties and symptom levels. © 2026 The Author(s).Öğe Determination of physical, aging and workability properties of asphalt binders with orange peel additives(Gumushane University, 2025) İnce, Ceren BeyzaIn the study, the effect of orange peels, a biomass source and a domestic waste, on the physical, aging, and workability properties of asphalt was investigated. For this purpose, modified asphalts were prepared by adding 13%, 15%, 17% and 19% ground orange peels to B 50/70 asphalt by weight. The physical properties of these asphalts were determined by softening point, ductility, and penetration tests, short-term aging by the rolling thin film oven (RTFO) test and workability properties by the rotational viscometer (RV) test. In addition, penetration index (PI) values were calculated to determine the sensitivity of orange peel-added asphalts to temperature. As a result of all the tests performed, it was observed that the hardness of asphalt binders and their resistance to high temperatures and oxidation increased with the addition of orange peels (at a rate of 19%) compared to pure asphalt. As a result, it was observed that orange peels, an energy source and waste material, have positive effects on the physical, aging and workability properties of asphalt binders. © 2025, Gumushane University.

The consequences of both social exclusion and language learning anxiety may prevent international students from achieving their goals, and negative psychological consequences may occur. Although social exclusion is a common situation faced by international students, the relationship between social exclusion and anxiety in language learning processes is poorly understood. Moreover, the mediating mechanisms affecting this relationship have not been revealed. This study examined the mediating role of resilience and mindfulness in the relationship between international students' perceptions of social exclusion and language learning anxiety. In the study, a relational survey model was employed. Participants were 335 students (170 female, 165 male, Mage = 20.46 years, SD = 3.51) who came to Türkiye for university education and enrolled in Turkish Language Teaching Application and Research Centres. "College Belongingness Questionnaire", "Foreign Language Learning Anxiety Scale" "Brief Resilience Scale" and "Mindful Attention Awareness Scale" were used for data collection. The results showed that the perception of social exclusion predicted foreign language learning anxiety. It was also found that resilience and mindfulness play a role in the relationship between social exclusion and foreign language learning anxiety. The importance of resilience and mindfulness in coping with the negative effects of social exclusion and foreign language learning anxiety was understood. © 2025 The Authors.
