Socioeconomic inequality is a persistent societal problem affecting various aspects of adolescent development. Existing studies have revealed that low socioeconomic status (SES) is associated with a higher prevalence of internalizing symptoms. However, little is known about the underlying factors that may mediate this relationship. The current study conducted path analyses to examine the role of academic performance and cyberbullying victimization as mediators of the association between family SES and internalizing symptoms (depressive symptoms and suicidal ideation). The sample consisted of 7333 middle and high school students (age 12 to 19 years) (50.8% female) participating in the Korean Children and Youth Rights Study. Findings indicated that SES was directly and negatively associated with depressive symptoms and suicidal ideation. There were indirect associations between SES and internalizing symptoms through academic performance and cyberbullying victimization. The findings suggest low family SES is significantly related to adolescents' internalizing symptoms, and academic performance and cyberbullying victimization are key mediators of the negative association between family SES and internalizing symptoms. Further longitudinal studies exploring the roles of family SES, academic performance, and cyberbullying victimization are suggested.

This study investigated the effectiveness of floating covers (FCs) in mitigating ammonia (NH3) and hydrogen sulfide (H2S) emissions from lab-scale swine slurry pits. Lab experiments were conducted over 125 days, comparing a treatment setup with FCs covering approximately 51.6% of the slurry surface to a control setup without covers. The results showed a significant reduction in NH3 emissions by 54.4% with FCs (p < 0.05), which was attributed to their ability to limit NH3 volatilization and promote crust formation. Although H2S emissions were also reduced by 22.7%, this decrease was not statistically significant, likely due to the complex factors influencing H2S production. These findings highlight the role of floating covers (FCs) in improving air quality within swine barns and reducing environmental pollution. By minimizing nitrogen loss as ammonia (NH3), FCs enhance nitrogen recycling into agricultural land, supporting sustainable nutrient management. This aligns with broader sustainability goals by addressing air quality concerns, reducing odors, and improving resource efficiency in livestock systems. This study offers an effective method to mitigate air pollution, providing a foundation for practical and sustainable agricultural practices. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to understand the mediating effect of workplace incivility on the relationship between nursing organizational culture and turnover intention among nurses. Design: A descriptive survey was used to collect data. The participants were 170 nurses with more than six months of clinical experience at university hospitals or hospitals with over 500 beds in South Korea. Methods: Data were collected using self‐report questionnaires. Collected data were analyzed using descriptive statistics, t‐test, ANOVA, Scheffé test, and Pearson's correlation. Baron and Kenny's three‐step hierarchical regression analysis and the Sobel test were used to determine the mediating effect of workplace incivility on the relationship between nursing organizational culture and nurses' turnover intention. Results: This study found a full mediating effect of workplace incivility on the association between relationship‐oriented culture and turnover intention (Z = −3.02, p = 0.003) and a partial mediating effect of workplace incivility on the association between hierarchy‐oriented culture and turnover intention (Z = 2.36, p = 0.018). Conclusion: This study empirically confirmed that nursing organizational culture and workplace incivility directly or indirectly influenced turnover intention, which highlights the seriousness of workplace incivility. Clinical relevance: This study suggests that there is a need to establish a concrete strategy to avoid a hierarchy‐oriented culture and create a relationship‐oriented culture. It is important to develop a variety of intervention programs to reduce workplace incivility in order to prevent nurses' turnover. [ABSTRACT FROM AUTHOR]

In this study, we aimed to investigate the regulatory effects of a green tea and java pepper mixture (GTP) on the gut microbiome and microRNA (miR)-221/222 expression in mice with dextran sulfate sodium (DSS)-induced colitis. Male C57BL/6J mice were divided into four groups: DSS-, DSS+, GTP50, and GTP100. In the GTP50 and GTP100 groups, GTP was orally administered to mice at doses of 50 and 100 mg/kg body weight, respectively, every day for 2 weeks, and colitis was induced in the DSS+, GTP50, and GTP100 groups by adding 3% DSS to their drinking water for 1 week. GTP was found to mitigate the severity of inflammation and the damage to goblet cells caused by DSS-induced colitis. The results showed that compared with the DSS- group, the relative abundance of Bacteroidetes was increased and that of Proteobacteria and Candidatus Melainabacteria was decreased in the GTP100 group. The ratio of Firmicutes to Bacteroidetes was also reduced in the GTP100 group. However, GTP administration did not modulate the microbial diversity. GTP administration upregulated the mRNA and protein levels of occludin and zonula occludens 1. In addition, GTP effectively downregulated the expression of miR-221 and miR-222. Overall, GTP altered the gut microbiota composition and downregulated colonic miR-221/222 expression in mice with DSS-induced colitis., Competing Interests: AUTHOR DISCLOSURE STATEMENT The authors declare no conflict of interest., (© 2024 The Korean Society of Food Science and Nutrition.)
