Aim
This study aims to determine the loneliness level and affecting factors in adolescents.
Materials and methods
This descriptive study was conducted between September 2022 and December 2022 in high schools which were located in a city in eastern Turkey. The sample was composed of 1956 students who were accessed using stratified and simple random sampling methods determined by power analysis. Data collection was performed using the Descriptive Characteristics Form and the UCLA Loneliness Scale-Short Form.
Results
Of the participating students, 67.3% had a hobby for which they spared time regularly, and 92.4%, 89.3%, and 76% were satisfied with their relationships with their mother, father, and friends, respectively. The UCLA Loneliness Scale mean score of the group was 14.23 ± 4.53. The scale mean score was found to be higher in girls; in those who had a stepmother, any speaking disability or a disease; did not have a very close friend; were in love; did not have an occupation or hobby for recreation; were not satisfied with the way they spend their free time, communication with parents and friends, and success in courses; and did not find their allowance adequate (p < 0.05).
Conclusion
This study found that the loneliness level was affected by gender, having a stepmother, having a disease or speaking disability, having a hobby or occupation, communication with individuals in the social environment, and satisfaction with course success and the allowance given by the family.

Investigation of Pre-Knowledge Cheating Using Response Time Model
This study aims to reveal the rate of Type I error in the detection of preknowledge cheating behaviors, and the rate of power of response time based on Kullback–Leibler divergence (KL) measure, and L person fit statistic under different conditions via modeling patterns of response accuracy (RA) and response time (RT), using a joint hierarchical model. 200 data sets were generated with 50 iterations that item responses were modeled with three parameter logistic model and RTs were modeled with the log-normal RT model under the conditions of test length and difficulty level of the compromised items for obtained means of Type I error rate of methods. In order to obtain the means power rate of the methods, 1,800 data sets were generated with 50 iterations under the conditions of test length, the difficulty level of the compromised items, the ratio of compromised items, changing in RT of the compromised items. Gibbs sampling algorithm is used as a Monte Carlo Markov Chain (MCMC) approach in estimating model parameters for each data set. In the cheating scenario, where item preknowledge examinees were selected from those with low ability level, the rate of fraudulent data was created as 5% of the 1,000 sample size. As a result of the study, it was found that the KL measure has a high power and Type I error rate mean values than person fit statistics L and L(l^t ) for RA and RT patterns under all conditions. In addition, it is seen that the KL measure for RA and RT patterns show the highest power rate mean values at medium test length, and when the RTs of the compromised items which have difficult and medium difficulty level fixed at 20 s and the ratio of compromised items is high.
Earthquakes cause severe destruction in the region where they occur. Children and adolescents are the group most affected group by earthquakes, and Post-Traumatic Stress Disorder is most common in this group. The age-related increase in Grip Strength varies between childhood and early adolescence. The purpose of the present study was to investigate the relationship between Post Traumatic Stress Disorder and Hand Grip and Hand Measurements of children exposed to the Kahramanmaraş-centered earthquake on February 6, 2023. The “Post-Traumatic Stress Disorder Response Scale for Children” was administered to 116 children who in children between the ages of 8 and 12 groups, and consent was obtained from the participants. Morphometric measurements of the hands of the children were measured with a digital caliper. Children’s hand Grip Strength measurements were made by using a digital hand dynamometer. The analysis of study data was performed with the SPSS (Statistical Program in Social Sciences) 25 software. Positive and statistically significant relationships were detected between right and left-hand Grip Strength and right and left-hand measurements of females and males (p < 0.05). Statistically significant and negative relationships were detected between PTSD and right and left-hand Grip Strength and right and left-hand measurements in females and males (p < 0.05).In the present study, it was detected that as post-traumatic stress disorder increases, hand Grip Strength decreases. We think that these findings will guide future prospective studies.
While the significance of motivation in the adoption of mobile learning has been well-documented in numerous studies, empirical evidence regarding the roles of cognitive, social, and affective needs remains limited. This presents a notable gap in the field of education concerning the influence of motivational factors on mobile learning acceptance. To address this gap, our study adopts a motivational perspective by extending the Technology Acceptance Model (TAM) with the Uses and Gratifications Theory (UGT). Our primary objective is to investigate the motivational variables influencing university students’ behavioral intention to use mobile learning. We collected data from 7,426 university students through an online survey. Subsequently, we employed factor analysis and the structural equation modeling for analysis. Our proposed model demonstrated a remarkable explanatory power, accounting for 76.7% of behavioral intention. Notably, the findings highlight the paramount influence of constructs rooted in the uses and gratifications theory (specifically, social needs, cognitive needs, and affective needs) on behavioral intention. These needs emerge as fundamental motivators in shaping the intention to use mobile learning. This study contributes valuable empirical evidence by incorporating the uses and gratifications theory into the technology acceptance model, shedding light on how this integration influences the intention to use mobile learning. It underscores the substantial roles played by cognitive, affective, and social needs in the realm of mobile learning. In light of these findings, the study delves into both theoretical and practical implications, offering a foundation for future research endeavors.
Cognizance, or the self-awareness individuals have of their cognitive processes, is a critical factor in adult learning and literacy, which are fundamental for personal and social development. This study aims to explore the psychometric properties of the instrument used and investigate how cognizance affects the academic achievement of new learners in literacy programs in Morocco. The research included 560 male and female learners, who were assessed using a cognizance scale designed for novice learners. The results showed significant correlations between cognizance and academic performance among these learners, indicating their ability to continue learning independently despite facing new challenges in learning to read, write, and do mathematics. This suggests that learners can overcome challenges through self-representation, self-regulation, self-adaptation, and understanding their abilities. This study has implications for improving education and developing programs to enhance cognizance and adult learning, as well as strategies to combat illiteracy. It also aims to deepen human understanding and enrich societies with knowledge and culture.
Objective: Engaging in excessive digital gaming can detrimentally affect physical and psychological health. This research aimed to examine the relationships between digital game addiction , classroom engagement, sleep deprivation, and mind-wandering and to test the mediating effect of sleep deprivation and mind-wandering on the relationship between digital game addiction and classroom engagement. Method: Employing a relational survey design, data were collected from a convenience sample of 750 Turkish adolescents (295 males, 455 females) aged 13-17 years, using an online cross-sectional survey. All participants were in middle or high school. Results: Digital game use varied; 154 (20.5%) did not play digital games. Among those who played digital games, the highest percentage played 0-1 hour per day, 188 (25.1%). Digital game addiction scores ranged from 7-35 (M = 13.57, SD = 5.90). Digital game addiction, sleep deprivation, and mind-wandering were associated with poorer classroom engagement. Sleep deprivation and mind-wandering mediated the relationship between digital game addiction and classroom engagement. Conclusion: The relationship between digital game addiction and classroom engagement appears to be at least partly explained by sleep deprivation and mind-wandering. Future research should investigate these variables across different age groups of adolescents, employing both qualitative approaches and longitudinal quantitative methods.
KEY POINTS What is already known about this topic (1) Digital game addiction is significantly associated with poorer classroom engagement. (2) Sleep deprivation and mind-wandering have been identified as significant predictors of classroom engagement. (3) The mechanisms driving the relationships between digital game addiction, sleep deprivation , mind-wandering, and classroom engagement remain less understood. What this topic adds (1) High levels of digital game addiction were associated with greater sleep deprivation and mind wandering, which in turn was associated with lower classroom engagement. (2) Sleep deprivation and mind wandering mediated the relationship between digital game addiction and classroom engagement. (3) These findings suggest that interventions aimed at reducing sleep deprivation and mind wandering may be especially beneficial for adolescents who experience poor classroom engagement due to digital game addiction.
Objective
The aim of this review was to assess the factors influencing the occupational stress of state security forces during the COVID-19 pandemic.
Methods
We conducted a scoping review using the Pubmed, Scopus, and Web of Science databases, adhering to the PRISMA statement standards and the guidelines for narrative syntheses.
Results
We included a total of 26 studies. The prevalence of stress varied from 22% to 87.2%. Factors that may have influenced the stress levels of police officers during the pandemic include not having basic personal protective equipment, having little or no rest periods between tasks, long working hours, fear of contagion to themselves or others, pressure to maintain law and order, emotion regulation and preparedness, sex, marital status, work experience, age, presence of chronic underlying illnesses, family-work conflict, lack of psychological support, and others. The long working hours, the fear of infecting themselves or others, the pressure to maintain law and order, sex, and age are the six main factors evaluated for more studies.
Conclusion
Organisational, situational, and personal factors may have influenced the stress levels of police officers during the pandemic, and measures need to be taken to minimise their impact.
The study aimed to examine the spiritual care experiences of nurses caring for gynecologic cancer patients. The study was conducted using a phenomenological design, one of the qualitative research methods. Nurses caring for gynecologic cancer patients were included in the study. In sample selection, the criterion sampling method, one of the purposeful sampling methods, was used, and the sample size was ten nurses. A semi-structured interview guide was used to collect the data. Content analysis was performed using the MAXQDA package program. The study was written based on the COREQ checklist. The nurses’ statements determined themes, sub-themes, and codes in line with the research findings. Accordingly, four themes were identified as “spiritual care practices,” “emotional effects of spiritual care,” “factors affecting spiritual care,” and “recommendations to improve spiritual care”. In line with the findings obtained, it is recommended that in-service training should be provided to nurses caring for gynecologic cancer patients to provide spiritual care at a professional level. Moreover, the excessive workload caused by working conditions should be reduced, and regulations and institutional policies should be established to increase the number of nurses.
Celecoxib derivatives that contain the pyrazole‐linked sulfonamide moiety were synthesized, and the in vitro inhibitory impacts of the aforesaid compounds against the lactoperoxidase (LPO) enzyme were researched. To this end, LPO was purified using the affinity chromatography technique with a yield of 12.63% (319.23‐fold). The results showed that the aromatic pyrazole compound (compound 1 ) containing 2,3‐dimethoxyphenyl functional groups was the most effective LPO inhibitor with a K i value of 3.2 ± 0.7 nM and noncompetitive inhibition type. The second section of the study tested the previously synthesized compounds to reveal their antioxidant and antimicrobial properties. The above‐mentioned compound also displayed high activity levels compared to standard antibiotics and antifungals, while all other compounds also showed antibacterial activity. In the three antioxidant methods we used, the compound with 2,5‐dimethoxy phenyl groups obtained from the reaction of the aromatic pyrazole compound with propionic anhydride in the presence of NEt 3 displayed the highest activity. Furthermore, molecular docking and molecular mechanics studies were conducted to complement and validate the experimental findings. The results obtained from these computational analyses are highly consistent with the experimental data.
Purpose
The limitations in cancer treatment and the inadequacy of classical methods have made it necessary to discover therapeutics in cancer treatment. The cytotoxicity of thymoquinone, which has quite different properties in terms of biological activities, in ovarian cancer cells, and the changes in the expression levels of apoptotic genes (p53/caspase-3 (casp-3)) were investigated.
Methods
In the study, thymoquinone (5, 50, 100, 250 and 500 µM and 24, 48, 72 hours) were applied to ovarian adenocarcinoma cancer cell line (OVCAR3), at different concentrations. Cytotoxic effect of thymoquinone on OVCAR-3 cells were analyzed by MTT method, and apoptotic and pro-apoptotic gene expression levels (p53, Casp-3) of thymoquinone in cancer cells were analyzed by quantitative real-time polymerase chain reaction.
Results
Thymoquinone, whose effect has been revealed in many types of cancer, was shown to significantly reduce the viability of OVCAR3 cancer cells depending on the dose and time (p < 0.05). It was also determined that Casp-3 and p53 gene expressions increased in OVCAR3 cells.
Conclusions
Considering the in-vitro cytotoxic activity and apoptotic gene expressions of thymoquinone, an important treatment agent, since it is a promising agent for the future of cancer treatment, more comprehensive studies may pave the way for its clinical use.

There is growing interest in the association between COVID-19-related stressors and quality of life. This study aimed to extend current knowledge by investigating the potential mediating roles of COVID-19 anxiety and COVID-19 burnout in the association between fear of COVID-19 and COVID-19 quality of life in nurses. A total of 300 nurses were selected by convenience sampling approach from a training and research hospital serving as a pandemic hospital in Turkey. COVID-19 anxiety, COVID-19 burnout, and COVID-19 quality of life data were collected using the self-reported questionnaires using both online and paper-and-pencil versions of the questionnaires. Structural equation modeling was used to conduct serial multiple mediation analysis. We found statistically significant associations among fear of COVID-19, COVID-19 anxiety, COVID-19 burnout, and COVID-19 quality of life. Serial multiple mediation analysis revealed that the association of fear of COVID-19 with COVID-19 quality of life was partially mediated by COVID-19 anxiety and COVID-19 burnout. These results indicate that the association of fear of COVID-19 with COVID-19 quality of life in nurses may be changed through COVID-19 anxiety and COVID-19 burnout, which appear to play serial multiple mediating roles in this association. These findings enrich our understanding of the associations among these psychological factors and suggest that focusing solely on fear of COVID-19 without considering the mediating effects of COVID-19 anxiety and COVID-19 burnout might not be adequate for reducing the COVID-19–impact on the quality of life among nurses.
Magnetic nanoparticles (MNPs) are produced for both diagnosis and treatment due to their simultaneous availability in magnetic resonance imaging (MRI) and magnetic hyperthermia (MHT). Extensive investigations focus on developing MNPs for individual MHT or MRI applications, but the development of MNPs for theragnostic applications has received very little attention. In this study, through efficient examination of synthesis conditions such as metal precursors, reaction parameters, and solvent choices, we aimed to optimize MNP production for effective utilization for MHT and MRI simultaneously. MNPs were synthesized by thermal decomposition under 17 different conditions and deeply characterized by transmission electron microscopy (TEM), x‐ray diffraction (XRD), and x‐ray photoelectron spectroscopy (XPS). The heating efficiency of MNPs under an alternating current (AC) magnetic field was quantified, while MRI performance was evaluated through agar phantom experiments. Our findings highlight the crucial role of benzyl ether in metal ion reduction and size control. Metal‐doped iron oxide MNPs displayed promise for MHT, whereas Mn‐doped iron oxide MNPs exhibited enhanced MRI capabilities. Consequently, five engineered MNPs were considered potential candidates for further studies, demonstrating their dual ability in MRI and MHT.
This study aimed to investigated the impact of Kahoot, ChatGPT, and traditional teaching methods on nursing students’ sexual health knowledge and attitudes. This quasi-experimental study was conducted using an online survey of 93 nursing students. Data collection instruments were implemented in three stages: pre-test, post-test, and follow-up test, measuring students’ levels of sexual health knowledge and attitudes. The training was conducted over a total of four hours, consisting of two hours per week for each group. Data were collected through tests prepared via Google Forms. After the training, it was observed that students in all three groups found the educational program beneficial and effective. In the follow-up test, students reported an increase in their confidence in managing sexual health-related issues. Statistical analyses indicated that the training delivered through Kahoot and ChatGPT was more effective in improving sexual health knowledge levels. At the same time, traditional education was more effective in improving sexual health attitudes by the end of the first month. The analyses also revealed that the change in students’ sexual health knowledge levels did not significantly differ among different educational methods (Kahoot, ChatGPT, and traditional education). Kahoot and ChatGPT educational technologies were effective in improving nursing students’ sexual health knowledge levels in repeated measurements. However, when considering the change between measurements, different educational methods had similar effects on sexual health knowledge levels and sexual health attitudes.
Green technology (GT) and the utilization of renewable energy (RE) are widely acknowledged as a catalyst for energy efficiency, economic growth, and a tool for combating environmental degradation. Although various studies have examined the ecological repercussions of these two improvements, they have primarily used traditional pollution indicators (namely, carbon emissions and ecological footprint) and ignored nations with the highest cleaner energy adoption. To bridge this gap, the present research seeks to analyze the relationship between GT, RE consumption, economic growth, trade, and load capacity factor in the top-10 renewable economies. In addition to environmental pollution indicators, the study utilizes the load capacity factor as a novel proxy for environmental quality and investigates the load capacity curve hypothesis using the Cross-sectional-autoregressive distributed lag model from 1990 to 2021. According to the empirical findings, all explanatory variables have a significant long-term effect on the load capacity. More precisely, GT and RE consumption contribute to the sustainability of the ecosystem, while trade increases the ecological deficit. Furthermore, the findings do not support the validity of the load capacity curve hypothesis, implying that the environmental restorative benefits of economic well-being may not manifest in the latter stages of economic growth. Given these findings, policymakers in the top-10 renewable economies should seize the environmental prospects offered by GT and RE and update trade and growth policies in a way that promotes biocapacity while simultaneously reducing the ecological footprint to reach the long-term sustainable development goals (SDGs), particularly SDGs 7 and 13.
The concept of love of life, which refers to a positive attitude towards one's own life, care for it and attachment to it, has recently captured the attention of researchers in the field of positive psychology. Despite its growing importance, there is a lack of research investigating the underlying mechanisms through which love of life impacts the flourishing and well-being of individuals. For the first time, the present study examined the mediating roles of optimism and hope in the association between love of life and flourishing in Turkish youth. The study comprised 374 young adults, aged between 18 and 24 years (55.3% female; Mean age = 20.94; SD = 1.78 years), who participated in an online survey assessing their levels of love of life, optimism, hope, and flourishing. Results from the mediation analysis revealed that love of life significantly predicted optimism, hope, and flourishing. Furthermore, optimism and hope had significant predictive effects on flourishing. Importantly, optimism and hope played a partial mediating role in explaining the positive influence of the love of life on individuals' flourishing. The findings suggest a positive association between love of life and heightened levels of optimism and hope. These psychological attributes, in turn, emerge as crucial factors contributing to increased flourishing. These results hold significant implications for the development of interventions focused on understanding how to foster the love of life and flourish through the cultivation of psychological strengths.
The successful transfer of complex loads from a storage rack system to the concrete slab is closely related to the performance of the connection between the baseplate and the upright. The relationship between moment and rotation strongly influences the performance of this connection. Various factors, including the arrangement and quantity of anchor rods and the direction of loading, impact the moment-rotation behavior in the baseplate connection. However, predicting the moment-rotation behavior of the baseplate-upright connection, considering the different loading directions and anchor configurations commonly found in commercially available storage racks, has not received sufficient attention. Thus, this study aims to investigate the behavior of five distinct baseplate models that employ two or three anchor bolts, subject to two different loading directions. The investigation is carried out through rigorous numerical simulations and meticulous experimental testing. By focusing on the moment-rotation curves resulting from the applied loads, the study aims to gain valuable insights into the performance of the baseplate-upright connections. Additionally, the validated finite element model is employed to examine the distribution of principal stress, providing crucial information about the connection’s structural integrity and potential failure points. Certain configurations were observed to outperform others in terms of energy dissipation and favorable moment-rotation characteristics. The configuration with three bolts located at the back of the upright (3B-B) outperforms with higher energy dissipation capacities and more favorable moment-rotation characteristics, while the configuration with two bolts vertically located at the back of upright (2B-V) is inferred to have inferior performance.
Background
While many studies have explored the direct impact of psychosocial factors on affective experiences, there remains a gap in understanding the specific factors that mediate the relationships between social support and affective outcomes.
Objective
The present study aimed to investigate the mediating role of self-esteem in the association between social support and affective experiences among a sample of Turkish undergraduate students.
Method
The study utilized an online survey to recruit 300 participants, with a majority of female participants (59.33 %). The age of the participants ranged from 18 to 28 years (Mage = 21.15; SD = 1.86). Participants completed the Multidimensional Scale of Perceived Social Support (Zimet et al., 1988), the Rosenberg Self-Esteem Scale (Rosenberg, 1965), and the Scales of Positive and Negative Experiences (Diener et al., 2010).
Results
The mediation model with bootstrapping technique analysis revealed that social support was significantly associated with self-esteem and positive affective experiences. Self-esteem was also significantly associated with both positive and negative affective experiences. Additionally, self-esteem was found to partially mediate the relationship between social support and both positive and negative affective experiences, indicating that self-esteem acted as a mediator in these associations.
Conclusions
These findings contribute to our understanding of the association between social support, self-esteem, and affective experiences and have implications for the development and implementation of interventions aimed at enhancing the positive effects of social support and self-esteem on affective experiences among young adults.
Background/aim
Microbiota awareness, nutritional literacy, and health literacy levels in adolescents have a significant impact on their health and well-being. This research was conducted to examine the relationship between microbiota awareness, nutrition literacy, and health literacy in adolescents.
Material and methods
This research was structured with a descriptive-correlational design. The study population comprised adolescents aged 10–19 years, living in Türkiye (n = 739), between June 2022 and February 2024. Data were analyzed using SPSS 22.0, G*Power 3.1, and R programming language 4.1.3.
Results
The total effect of the health literacy variable on nutritional literacy was 0.2311, and this was statistically significant at a 95% confidence interval (CI) (p < 0.05). In terms of the health literacy variable, the direct effect of the nutrition literacy variable on the microbiota awareness variable was 0.2888, and this was statistically significant at the 95% CI (p < 0.05). In terms of the nutritional literacy variable, the direct effect of the health literacy variable on the microbiota awareness variable was 0.1707, and this was statistically significant at the 95% CI (p < 0.05). Nutrition literacy had a partial mediating role in the effect of health literacy on microbiota awareness (lower limit CI: 0.045; upper limit CI: 0.0894). The most accurate prediction of machine learning approaches to predict microbiota awareness was made with random forest with shapley additive explanations values, and the most important variable that should be in the model to predict the microbiota awareness variable was the nutrition literacy variable.
Conclusion
Microbiota awareness increased as health literacy and nutrition literacy increased. In the machine learning approach prediction, the most important variables affecting microbiota awareness were health literacy and nutritional literacy. Longitudinal studies on microbiota awareness are recommended.
This study assessed the occupational health and safety conditions in a furniture manufacturing facility, focusing on key environmental factors such as noise, lighting, thermal comfort, and dust exposure. Noise measurements recorded levels as high as 95.3 dB(A) during CNC machine operations, exceeding legal exposure limits of 87 dB(A), posing significant risks to workers’ hearing health. Lighting assessments showed levels ranging from 134 to 247 lux in production lines, which falls below the recommended threshold of 300 lux for adequate visibility. Thermal comfort was evaluated with temperature readings at 14.2 °C and relative humidity at 43%, revealing marginal comfort conditions that could reduce worker efficiency and satisfaction. Dust exposure measurements indicated respirable dust concentrations reaching 3.69 mg/m³ in the cutting department, which is close to the permissible exposure limit of 5 mg/m³, raising concerns about long-term respiratory health. These findings suggest several measures to improve workplace safety, including enhanced engineering controls, mandatory personal protective equipment (PPE), improved lighting systems, optimised thermal conditions, and advanced ventilation to reduce dust exposure. This comprehensive evaluation provides critical insights for improving furniture factories’ occupational health and safety practices.
