Objectives: As the Korean construction industry increasingly relies on foreign workers to address labor shortages, limitations of conventional safety education, characterized by one-directional instruction and insufficient linguistic adaptability, have emerged as a critical risk factor. These approaches fail to accommodate language barriers and heterogeneous learning needs, thereby increasing accident risks and hindering workplace integration. This study proposes an intelligent safety education framework and an AI-driven training architecture for foreign construction workers in Korea, integrating perspectives from construction safety, educational technology, and artificial intelligence. Methods: The proposed framework con ceptualizes safety education as a progressive process comprising four stages: digitized, adaptive, immersive, and predictive. Based on this framework, the architecture leverages Large Language Models (LLMs) and multimodal data analysis to automatically generate multilingual, context-aware training content and to deliver personalized learning pathways according to individual proficiency levels and risk profiles. Results: An implementation case demonstrates the technical feasibility, scalability, and regulatory compatibility of the proposed system with Korean industrial safety standards. Conclusions: The findings suggest that the proposed approach can enhance safety education in multicultural construction environments and contribute to the development of a sustainable, technology-driven safety culture that supports both safety competency development and social inclusion.

Objectives: This study was conducted to analyze the utilization status of the National Long-Term Care Insurance system, which was introduced to address the surging demand for elderly care due to rapid population aging, and to seek sustainable development strategies. Methods: The analysis was performed using the National Health Insurance Corporation's Senior Cohort 2.0 database from 2008 to 2019. Results: The incidence rate of long-term care certification has been continuously increasing since 2011, reaching 1,346 for men and 2,117 for women per 100,000 population in 2019. The rate for women was notably higher than for men, and the gap widened over the study period. The monthly average utilization rate of long-term care benefits peaked in 2013 (90.5% for men and 93.0% for women) but maintained an overall increasing trend. Home-visit care accounted for the highest proportion, with a utilization rate of 41.6% for men and 42.8% for women in 2019. Furthermore, the monthly average usage days for facilities (29.1 days for men and 29.5 days for women) and nursing hospitals (27.1 days for men and 27.9 days for women) remained consistently high, while the usage days for day and night care services showed a steady increase, reaching 28.3 days per month for men by 2019. Conclusions: To address the increase in long-term care demand, it is essential to improve the equity of the grade system, reduce out-of-pocket costs, and integrate related services such as those from nursing hospitals. Additionally, it is necessary to foster a workforce with practical caregiving skills and ensure a stable working environment to enhance professionalism and reduce turnover.

Objectives: This study examined the associations of breastfeeding experience, menopause age, and oral health behaviors with health-related quality of life (HRQoL), assessed using the EQ-5D index, among middle-aged and older Korean women. Methods: Data from 3,634 women aged ≥40 years who participated in the 2019, 2020, and 2022 Korea National Health and Nutrition Examination Survey were analyzed. Breastfeeding experience, menopause age, oral health behaviors, and functional oral health indicators were included as independent variables. Results: Breastfeeding experience was positively associated with HRQoL in unadjusted and partially adjusted models, but the association was not significant after full adjustment. Menopause age showed no significant association with HRQoL. In contrast, functional oral health indicators—particularly the absence of chewing discomfort and a greater number of remaining teeth—were consistently associatedwith higher HRQoL. Conclusions: Breastfeeding experience was not independently associated with HRQoL after accounting for socioeconomic and health-related factors, and menopause age showed no association with HRQoL. Functional oral health, especially chewing ability and tooth retention, emerged as a key determinant of HRQoL among middle-aged and older women.
