Abstract
Purpose: This study analyzed the safety and health responsibilities in industrial sites, which were emphasized after the comprehensive revision of the Industrial Safety and Health Act, from a legal perspective. Research design, data and methodology: It will present an analysis of the obligations regarding safety and health measures and the legal responsibilities for violations under the Industrial Safety and Health Act through normative analysis, case studies, and examination of precedents. Results: Employers and safety and health stakeholders face a high risk of incurring both criminal liability and civil damages for violations of the Industrial Safety and Health Act. The 2020 amendment to the Act has strengthened the preventive measures obligations of contractors, confirming that policy changes, such as bidding restrictions for commissioning organizations, have expanded the scope of responsibility. Conclusions: To prevent industrial accidents, it is essential to strengthen legal education for safety and health stakeholders, improve the accident investigation system, and clarify responsibilities. At the same time, the need for institutional improvements to enhance the fairness and predictability of legal applications is emphasized to resolve the controversy over excessive criminal penalties. The cultivation of personnel equipped with technical and legal practical capabilities in safety and health management, along with the establishment of proactive cooperation systems, is proposed as a key task for creating a no-accident working environment.
Abstract
Purpose: This study aims to investigate the causes of fire and explosion accidents in oil storage tanks and to propose preventive improvement measures using the PHAST (Process Hazard Analysis Software Tool) simulation method. By analyzing representative domestic cases—namely the 2018 Goyang oil depot fire, the 2021 Yeosu chemical plant explosion, and the 2025 Ulsan Onsan oil tank explosion—this research identifies common technical and managerial shortcomings, such as vapor leakage, vent system defects, and poor maintenance of flame arresters. Research design, data and methodology: The study applied PHAST simulations to evaluate accident scenarios under varying environmental and operational conditions, including gasoline release volume, atmospheric pressure, and wind speed. The simulation revealed that thermal radiation from a pool fire could reach up to 95 meters with a peak intensity of 20 kW/m², while a BLEVE could result in wide-area damage due to fireballs and overpressure effects. Based on these findings, the study proposes enhancements to monitoring systems, systematic inspection protocols, and on-site emergency response training. Conclusions: These integrated safety measures are expected to minimize damage and prevent recurrence. Future research should focus on incorporating emerging technologies and big data analytics to establish a more predictive and proactive risk management framework for hazardous material storage.
Abstract
Purpose: The purpose is to identify hazardous and risk factors by utilizing the risk assessment theory implemented in construction sites, analyze repetitive accident cases and risk factors, derive risk factors by type of work, systematically analyze and evaluate them, predict and manage the possibility of accidents, and present an effective plan to reduce accidents by effectively applying them in the field. Research design, data and methodology: This paper targets metal window construction work being carried out at construction sites, and examines accident types, risk factors, and cases by work type, and analyzes them using statistical data. from domestic and international academic A, papers, and research institutes. Result: There are many volatile elements at construction sites. If we identify and analyze the risk factors at the workplace, establish risk measures, and conduct risk assessments, we can reduce industrial accidents and thus reduce productivity loss. Conclusion: Based on various data from construction sites, we can propose risk assessment safety measure for each type of work and improve the safety and health level of the workplace by introducing an effective safety management system.
Abstract
Purpose: This study aimed to examine whether self-esteem mediates the relationship between social capital and life satisfaction among older men in South Korea. Research design, data and methodology: Data were obtained from the 18th Wave of the Korea Welfare Panel Study (2023). A total of 386 men aged 65 and older were analyzed. Key variables included components of social capital (trust, reciprocity, and networks), self-esteem, and life satisfaction. Demographic characteristics such as age, income, education, and marital status were included as control variables. Mediation analysis was conducted using SPSS. Results: Life satisfaction was significantly lower among older men with lower education, no spouse, and lower income. Trust and reciprocity positively affected life satisfaction. Self-esteem was shown to partially mediate the relationship between social capital and life satisfaction, indicating that social capital increases self-esteem, which in turn enhances life satisfaction. Conclusion: Strengthening interpersonal trust and reciprocity can improve both self-esteem and overall life satisfaction in older men. The findings suggest the need for gender-sensitive welfare programs that promote social participation and psychological well-being to reduce social isolation and suicide risk among elderly men.
Abstract
Purpose : The purpose of this study is to diagnose the safety management problems of the Korean construction industry and to suggest a direction to improve the safety level of the construction industry in the future. Method : Using the time series data, we analyzed the number of construction accident victims, accident rate, number of deaths, and mortality rate after the enactment of the Occupational Safety and Health Act, and diagnosed the problems of the construction safety management system and sought solutions. Results: The safety level of the construction industry has been partially improved, but the number of disaster victims is still increasing, and problems such as lack of effectiveness of the safety management system, field work-oriented method, and subcontracting structure are continuing. Conclusions: In order to improve the safety management of the construction industry, it is necessary to shift away from the field-oriented production method to the modular construction method, simplify and clarify the safety management system, and improve the overall social system. Through this, more effective measures can be prepared to prevent safety accidents in the construction industry.

Future research should integrate external variables and machine learning methods to enhance prediction accuracy and monitor emerging health concerns.
Abstract
Purpose: This study explores the impact of cost-cutting practices in the multilayered subcontracting structure of the construction industry on the reduction of occupational safety and health management costs (OSHMC). Research design, data and methodology: By analyzing legal and contractual limitations of the current system, and the shortcomings of existing cooperative safety models, this study aims to identify structural issues and suggest alternatives. Results: The findings indicate that subcontracting cost reductions often lead to the omission or reduction of essential safety expenses, including the deployment of safety managers and training programs. Current institutional frameworks—such as mandatory contract clauses, cost adjustment systems, and partial prepayment models—show limitations in ensuring actual safety implementation, particularly for small subcontractors. Conclusions: Based on the analysis, this study proposes an 'Automated Safety Cost Linkage and Guarantee Platform' that ensures real-time calculation, monitoring, and validation of safety expenditures through a digital system. The platform aims to enhance transparency, prevent cost shifting, and improve safety outcomes, ultimately contributing to a safer and more sustainable construction industry.
Abstract
Purpose: This study investigates the environmental impact of vehicle washing station effluents on surface water quality in Gilgit City, Gilgit-Baltistan, Pakistan. With an increasing number of car wash stations washing 15–30 vehicles per day and consuming 150–350 liters per vehicle, large volumes of untreated wastewater are discharged directly into nearby streams. Research design, data and methodology: Wastewater samples were collected from three major stations—Nagaral, Dumiyal, and Danyore—and analyzed for physicochemical parameters (pH, turbidity, EC, TDS, salinity, K, PO₄, CaCO₃, and Na) using standard laboratory methods. Macroinvertebrates were sampled using hand nets, and a questionnaire survey was conducted with station staff to document washing practices and water use. Results: ANOVA results revealed statistically significant differences (p<0.05) in TDS, EC, salinity, K, and PO₄ between sites. The highest EC (2.2 mS/cm) and salinity (524 mg/L) were observed at Dumiyal, while Nagaral showed elevated CaCO₃ (213 ppm). Macroinvertebrate data indicated the presence of pollution-tolerant Diptera larvae at two sites. Conclusions: Most parameters exceeded WHO recommended limits, indicating ecological degradation and potential health risks. The findings highlight the urgent need for regulation, treatment, and reuse of vehicle wash wastewater. Future studies should assess heavy metal contamination to better understand long-term environmental and public health implications.
Abstract
Purpose: This study empirically investigated how physicians' coaching leadership influences word-of-mouth and revisit intentions, with patient satisfaction and brand attachment serving as mediators in Korean primary healthcare institutions. Research design, data and methodology: An online survey was conducted with 306 adults who had utilized primary healthcare institutions within the past three months. To address multicollinearity issues among coaching leadership sub-factors, PLS-SEM analysis was performed using structural multicollinearity modeling and orthogonalization methods. Results: All research hypotheses were supported through systematic competitive model comparison, with Model C (endogenous variable covariance model) demonstrating superior fit indices (SRMR=0.044, NFI=0.923, GoF=0.772). The sequential structure of coaching leadership was confirmed (Direction → Development: β=0.810, p<0.001; Development → Performance: β=0.621, p<0.001; Performance → Relationship: β=0.625, p<0.001), with patient satisfaction (R²=0.758) and brand attachment (R²=0.784) demonstrating strong mediating effects. Word-of-mouth intention (R²=0.795) and revisit intention (R²=0.815) showed high explanatory power. Mediation analysis revealed both complete mediation patterns (VAF=1.000) for individual coaching dimensions and partial mediation effects (VAF=0.371-0.391) for comprehensive pathways. Among participants aged 65 and older, brand attachment exhibited a stronger influence on revisit intention compared to younger groups (β=0.728 vs 0.483, p<0.01). Conclusion: This study empirically demonstrated the mechanism by which physicians' coaching leadership induces positive behavioral intentions through patient satisfaction and attachment. These findings provide practical implications for the development of patient-centered healthcare service policies and for quality improvement in primary healthcare.
Abstract
Purpose : We would like to analyze the problems of the construction safety management system at small construction sites and review the domestic construction safety management system to suggest institutional improvement measures to reduce industrial accidents. Survey : This study evaluated the effectiveness of BBS by conducting a survey of 30 people working at small construction sites with construction costs of less than 5 billion won during 2024. Analysis : It proposed ways to form a BBS circulation structure by sharing safety before work, guiding risk, and using checklists during work, and improving workers' safety behavior through data-based safety measures. Conclusion: BBS was applied to small construction sites to raise safety awareness, and systematic safety management and disaster prevention measures using checklist-based big data were proposed.
Abstract
Purpose: This study aimed to analyze the current status of elderly medical welfare acilities in Korea, examine the correlation between elderly population and facility distribution, and propose safety management strategies with a focus on fall prevention. Research design, data and methodology: Data on elderly population and facility distribution across 17 regions in Korea (as of 2025) were collected. Pearson’s correlation analysis was conducted to examine the relationship between population size and facility numbers. Regional disparities were identified through comparative analysis, and previous studies were reviewed to assess fall incidence patterns in long-term care institutions. Results: A moderately strong positive correlation (r=0.78) was found between elderly population and facility numbers. However, regions with a high elderly ratio, such as Jeonnam, Gyeongbuk, and Jeonbuk, lacked sufficient facilities, revealing significant disparities. Falls were the most frequent incidents in long-term care institutions, occurring mainly in beds, bathrooms, and shared spaces.Conclusions: Although elderly medical welfare facilities have expanded with population aging, regional imbalances remain. Policy efforts should focus on (a) region-specific infrastructure expansion, (b) qualitative improvements in facilities, (c) ICT-based preventive management, and (d) integration with community care. This study provides baseline evidence for elderly care policy and fall prevention strategies in the context of a super-aged Korean society.
