Abstract
Purpose: It is of great significance to look at the relationship between the mother’s working condition and the child’s health status because the mother’s influence on their child is very significant. In this context, this research explores the relationship between a mother’s working conditions and their children’s mental health. Research design, data and methodology: This research uses the National Longitudinal Survey of Youth 79 (NLSY79) and the National Longitudinal Survey of Youth Children and Young Adults 79 (NLSY-CH79) data. It uses data linking mothers’ NLSY79 data with children’s NLSY-CH79 data. This research first performs the OLS regression on the CES-D mean to examine how the mother’s income and working time affect their children’s mental health. In addition, this research uses the ordered logistic regression for each CES-D item to check the robustness. Results: This research indicates that increased children’s stress has a very strong association with decreased mother’s number of working weeks. Conclusions: The results imply that the decrease in working weeks of mothers can be connected with the increase in their children’s stress due to the mother’s intervention. This research also shows that the children’s stress increases as the mother’s income increases, although it decreases as total net family income increases.
Abstract
Purpose. The purpose of this study was to investigate the impact of climate change on public health, particularly focusing on vulnerable populations in South Korea. The study aimed to examine the relationship between climatic variable temperature, precipitation, humidity, and wind speed—and the prevalence of environmental diseases (cardiovascular, respiratory, cancer related, heat-related illnesses, and mental disorders) across different age groups (1-14, 15-39, and 40+). Research Design, Data, and Methodology Using data from meteorological stations and the Health and Medical Big Data Open System, covering the period from 2019 to 2023, the analysis involved statistical methods, including linear regression and correlation analysis, using R software. Results: The results showed strong interrelationships among climate variables, particularly negative correlations between precipitation, wind speed, and temperature. However, the correlation between climate factors and health outcomes was generally weak, with only modest associations between temperature and environmental diseases in the elderly population. Additionally, scatter plot analyses confirmed the lack of a significant relationship between temperature and disease prevalence. Conclusion: These findings suggest that the health impacts of climate change are likely mediated by additional factors such as socioeconomic disparities, healthcare accessibility, and urban conditions. The study emphasizes the complexity of climate-related health risks, calling for localized, multidisciplinary interventions, such as climate-resilient healthcare systems and infrastructure, to mitigate these challenges. By integrating age-specific analyses, this research provides unique insights and underscores the urgency of proactive measures to protect vulnerable populations from evolving climate-induced health risks.

By utilizing these improvements, we intend to further maximize the effectiveness of the app. and provide a safer use environment for users. establishment of effective IAQ management policies and the creation of healthier learning environments.
Abstract
Purpose: Students spend long hours studying and living in school environments, making indoor air quality (IAQ) in school buildings a critical factor directly affecting their health and learning performance. This study aimed to assess the current status of IAQ in school buildings and analyze the effects of per capita occupancy volume, ventilation methods, and spatial characteristics on IAQ to propose improvement strategies. Measurements of particulate matter (PM10, PM2.5), carbon dioxide (CO₂), and total volatile organic compounds (TVOCs) were conducted in six locations, including classrooms and public spaces. The measured levels were compared to IAQ maintenance and recommended standards. Results indicated that particulate matter and TVOCs were within recommended levels across all locations. However, CO₂ exceeded recommended standards in classrooms with smaller per capita occupancy volumes, especially in enclosed classrooms relying solely on mechanical ventilation. Conversely, spaces incorporating natural ventilation showed relatively lower CO₂ concentrations. This study empirically analyzed various factors affecting IAQ in schools and provides practical ecommendations for improvement, such as enhancing ventilation systems, utilizing air-purifying plants, and installing CO₂ sensors. These findings are expected to contribute to the establishment of effective IAQ management policies and the creation of healthier learning environments.
Abstract
impacting pollutant concentrations. This study investigated particulate matter (PM-10 and PM-2.5) and carbon dioxide levels during cooking under three ventilation scenarios: no ventilation, range hood operation only, and range hood operation with windows open. The experiment used three food types—pork belly, mackerel, and dumplings—prepared on a gas stove. IoT air quality sensors measured pollutant concentrations at specific kitchen and room locations. Results revealed substantial variations in particulate matter increases across different ventilation methods: No ventilation demonstrated the most dramatic pollutant concentration increases, with mackerel showing the highest rise: PM-10 increased 50.9 times, PM-2.5 increased 44 times. Range hood only operation showed moderate pollutant concentration increases, where mackerel again displayed significant rises: PM-10 increased 12.1 times, PM-2.5 increased 9.44 times. The range hood with windows open approach presented the lowest pollutant concentration increases, representing the least impact on particulate matter levels and proving the most effective ventilation method. The study conclusively demonstrated that simultaneous use of natural and mechanical ventilation is most effective in managing indoor air quality during cooking. By providing empirical evidence of ventilation's impact, the research offers practical guidelines for reducing indoor air pollution generated during routine cooking activities

Abstract
Purpose: The purpose of this study is to compare and analyze the differences in general characteristics (gender, age, educational background, presence of spouse, alcohol consumption) and cognitive function between elderly individuals aged 65 or older with mild cognitive impairment (MCI) in Buan, Jeollabuk-do. Research design, data and methodology: This study evaluated cognitive function among 345 elderly participants using K-MOCA. Data were collected from July 10, 2024 to Aug. 10, 2024. Results: The analysis revealed statistically significant differences between the elderly with MCI and those with normal cognitive function, particularly in age and education level. Those in their 70s or older and individuals with less than a university education were at a higher risk of MCI. Sub-item analysis of K-MOCA showed significant cognitive function differences in areas such as spatial execution ability, vocabulary, attention, sensitive power, delayed recall, and sentence power, with MCI patients performing worse than the normal group. Conclusions: This study highlights the importance of demographic factors such as age, education, cohabitation with a spouse, and alcohol consumption in the cognitive health of the elderly. These findings emphasize the need for early diagnostic tools, such as K-MOCA, to identify at-risk individuals and intervene early to prevent progression to dementia
Abstract
This study explores the role of transformational leadership in promoting the holistic well-being of Vietnamese international students, with a specific focus on improving their college life adaptation and satisfaction in Korean universities. The research examines the structural relationships between transformational leadership, college life adaptation, and satisfaction among 297 Vietnamese international students attending seven universities in Seoul, Korea. The findings indicate that while charisma, a key component of transformational leadership, did not significantly influence either college life adaptation or satisfaction, motivation and intellectual stimulation positively affected college life adaptation, and motivation and individualized consideration enhanced college life satisfaction. The limited impact of charisma may reflect cultural and contextual factors, as Vietnamese students from collectivist cultures often prioritize practical and emotional support over symbolic or inspirational traits. Furthermore, the unique academic and social challenges faced in Korean universities may diminish the relevance of charisma relative to other leadership components. These findings suggest that enhancing motivation and intellectual stimulation can improve adaptation to college life, while focusing on individualized consideration can directly increase satisfaction. Moreover, the results hold broader relevance for international students from diverse cultural backgrounds who face similar challenges, underscoring the importance of culturally sensitive leadership and support strategies. This study provides valuable insights for the development of culturally responsive teaching and support systems in Korean universities to enhance the holistic well-being of Vietnamese international students throughout their academic journey.
Abstract
Purpose: A resource circulation management system can be established by operating and managing power generation facilities using landfill gas, and economic feasibility can be confirmed through the impact of landfill gas on climate change and the absolute value that can be used as a resource. Research design, data and methodology: After investigating the generation of landfill gas by visiting Nanjido and metropolitan landfill sites in Seoul, the environmental impact and economic evaluation can be conducted through the emission coefficient of whether it can be used as an energy resource. Results: Currently, the Nanji landfill was completed in 1993 and is being used as a Nanji camping site after stabilization work such as cover and water curtain was completed to solve environmental problems that have occurred. The Seoul metropolitan area landfill was selected after the completion of the Nanji landfill, and the landfill has been underway so far, and unlike Nanji landfill, it aims to implement eco-friendly treatment facilities. Conclusions: Waste generated in future generations also inevitably needs to be disposed of, so you can expect an optimized management plan to reduce the disgust of local residents and maximize the need by changing the perception of landfill as an eco-friendly space rather than a simple waste disposal facility.
