This study investigates the internal structure of the Habitat and Riparian Health Index (HRI) by identifying conditional dependencies among its components and the mechanisms that form grade boundaries, rather than treating HRI as a simple arithmetic sum. Using the 2024 national river assessment dataset, the analysis combined bootstrap-supported Bayesian Networks for stable dependency inference with classification decision trees for explicit grading rules and threshold identification. A multi-criterion priority scheme integrating network centrality, contribution to total-score variability, and classification contribution was also applied to derive management priorities within and across basins. Across all basins and analytical perspectives, Flow Velocity Diversity consistently emerged as the most influential component. It occupied the central position in the dependency structure and accounted for the largest share of variability in the composite score, indicating that it operates as a system-level outcome in which channel morphology, bed condition, and anthropogenic constraints converge. The grading mechanism was strongly asymmetric. Deficiencies in riverbank protection functioned as a dominant trigger for rapid grade deterioration, whereas attainment of the highest grade required a conjunctive and non-linear pathway in which sufficient flow heterogeneity was accompanied by the sequential resolution of structural constraints, particularly those associated with transverse structures and embankments. Basin-level comparisons further showed that network structures were not interchangeable, with the Nakdong River basin exhibiting the most distinct configuration and basinspecific priority patterns. These results imply that management should separate strategies aimed at preventing degradation through bottleneck control from strategies aimed at achieving top-tier conditions through coordinated, multi-component interventions.

Purpose: This study aimed to derive meaningful implications by comparing and analyzing community-based programs, such as the Public Health Center Home Visiting Health Care Program, which serve as key initiatives for the prevention and management of frailty among older adults. Methods: We used a domestic search engine to input keywords such as ‘aging’, ‘weakness’, ‘home health care’, ‘home nursing’, and ‘care services’, and collected and analyzed the searched data. Results: Various programs addressing physical activity, nutrition, social participation, cognitive health, and depression management are currently operated by public health centers, local governments, and the National Health Insurance Service (NHIS). Among these, the Public Health Center Home Visiting Health Care Program plays a central role in frailty management through direct visits by nurses to the homes and facilities of older adults, contributing to the promotion of healthy aging and the prevention of long-term care dependency. Conclusion: To strengthen its impact, the program should be expanded beyond the current focus on low-income and vulnerable seniors to encompass the broader elderly population. Moreover, the development and dissemination of specialized frailty management interventions are essential. It is also recommended that training programs be established to enhance the case management competencies of multidisciplinary professionals involved in the program, enabling them to better address the integrated health and social care needs of older adults. Further research is warranted to assess the cost-effectiveness of community-based frailty prevention and management programs by developing measurable indicators that validate their outcomes and effectiveness.

This study investigates the gap between statutory calculation standards and actual field conditions in estimating Occupational Safety and Health Management Expenses (OSHME) for large-scale construction projects. The current fixed-rate method, based on construction type and cost, fails to account for on-site factors such as project complexity, duration, and workforce structure, often leading to discrepancies between estimated and actual costs. To address this, data from 21 completed projects over KRW 5 billion were analyzed. Multiple regression analysis was conducted using variables including material and labor costs, project duration, floor area, number of floors, and the number of safety personnel. The results showed a significant statistical difference between calculated and actual OSHME, and the proposed model explained 95.3% of the variance (R2 = 0.953). Variable selection techniques were applied to improve prediction accuracy by addressing multicollinearity. The model offers practical value for early budgeting and supports policy improvements that align safety expenses with real on-site needs, in order to more effectively prevent industrial accidents.

With the rapid development of economic globalization and the shipping industry, seafarers have been working at sea for a long time, facing psychological problems such as loneliness, depression, and frustration, which pose serious threats to their physical and mental health. The occurrence of psychological symptoms among crew members during their service on board and during their vacations was analyzed through psychological surveys. Research has found that crew members are prone to psychological problems such as obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, and paranoia during their time on board. The two stages with a relatively high probability of developing psychological problems are: one month and 3-6 months after starting working on board. In response to these issues, some onboard management measures and shore-based support measures have been proposed.

Objective: To examine published qualitative studies that can inform occupational therapists about potential intervention targets to improve health outcomes in homeless communities. Methods: A search was conducted for pertinent studies in the following databases: PubMed, Ovid, and CINAHL. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed to extract relevant data. Only research published after 2011 in English-language peer-reviewed journals was included. Twelve of the 1,162 identified articles satisfied the requirements for inclusion. Results: Individuals experiencing homelessness had higher levels of food insecurity, mental health conditions, and inadequate management of chronic conditions than those with a stable residence, all of which were successfully treated through occupational therapy. Conclusion: The scope of practice of occupational therapists allows for holistic treatment approaches to address the biopsychosocial health of homeless individuals at all levels of need and suggests that occupational therapy intervention initiatives are appropriate to address occupational justice for this population

This study analyzed the factors affecting the effectiveness of the Chemical Hazard Risk Management (CHARM). A survey was conducted on 104 learners who participated in the Risk Assessment training course at Occupational Safety and Health Training Institute. Through a self-administered questionnaire, the effect of personal characteristics, corporate characteristics, and safety and health level of the company on the effectiveness of chemical risk assessment was investigated. As a result of statistical analysis, the safety and health level of the company had a positive (+) effect on the effectiveness of Chemical Hazard Risk Management(CHARM), but personal characteristics and corporate characteristics had no relation to it. This study can be used as basic data for further research related to chemical risk assessment in workplaces.

Occupational safety and health management expenses in the construction industry are statutory and separately included in the cost statement to prevent occupational accidents and health problems. The expenses are determined by multiplying the standard amount by the rate decided according to construction types and scales. However, the current expense appropriation method does not properly reflect the recent changes in the construction industry such as industry size, industry diversification, and social atmosphere about safety reinforcement. This study surveyed 1579 questionnaires in total and analyzed expense execution rate and proportion of each expense category. The expense execution rate was relative higher in complex construction (e.g., heavy construction = 126%, civil engineering = 125%) and long-period project (equal to or over 48 months construction = 133%) compared to general construction (98~116%) and short-period project (less than 48 months construction = 115%). The proportion of spending expenses was higher in the category of safety manager labor costs (25~52%), safety facility costs (22~40%), and personal protective equipment costs (10~25%). The analysis results of the study can be utilized in revising the standard expense appropriation method by reflecting the current usages of the occupational safety and health management expenses in the construction industry.

The Severe Disaster Punishment Act had recently been established in order to promote safety and health (OSH) management system for severe accident prevention. OSH management system is primarily designed based on risk assessments; however, companies in industries have been experiencing difficulties in hazard identification and selecting proper measures for risk assessments and accident prevention. This study intended to introduce an accident analysis method based on epidemiological model in finding hazard and preventive measures. The accident analysis method employed in this study was proposed by the U.S. Department of Energy. To demonstrate the effectiveness of the accident analysis method, this study applied it to two accident cases occurred in construction and manufacturing industries. The application process and results of this study can be utilized in improving OSH management system and preventing severe accidents.

This study examined the certification effects of safety and health management system (SHMS) on the establishment level of SHMS and accident statistics in construction industry. This study obtained the establishment level of SHMS for 106 construction companies surveyed from our previous study. In addition, three major accident statistics (mortality rate, accidental mortality rate, and injury rate) for the companies were collected from the database in Korean Occupational Safety and Health Agency. The statistical analysis results revealed that the establishment level for SHMS certified companies was significantly higher than those for uncertified or certification preparing companies. Furthermore, SHMS certified companies showed significantly smaller accident statistics compared to uncertified or certification preparing companies. The results of this study support the positive effects of SHMS on reducing major industrial accidents in construction companies.

It was legislated in Korea that the small-sized enterprise with fewer than 50 employees should appoint at least one managing officer in order to improve safety and health of the employees since 2016. Study on the effectiveness of this legislation is hardly found, however. This study tried to evaluate effectiveness of the regulations for appointing the safety and health management officer in small-sized manufacturing companies and make suggestions to improve it. It was done by pairwise comparison between the level of safety and health achievement of 52 companies before and after the legislation. A scorecard system and questionnaires were devised for assessing the level of safety and health achievement and surveying awareness and practice of the regulation in the field. Results from quantitative and qualitative analyses performed in the study confirm that the safety and health achievement score has increased significantly after appointing the managing officer. It is also revealed that the lack of expertise and motivation of the appointed officer would yield pointless outcomes. Recommendations to make it better the effectiveness of the regulation are: to administrate requirements more strictly to be appointed as a safety and health management officer, to revise the curriculum to train the expertise of the appointed officers, and to expand financial support of the government to settle the safety and health management system.

최근 회전 회전기계의 건전성 관련 연구가 활발하게 진행중이며, 조선업의 대표적인 회전기계인 갠트리 크레인에도 이를 적용하고자 하는 연구가 활발하게 진행되고 있다. 하지만 조선업의 갠트리 크레인의 경우 상대적으로 낮은 RPM으로 구동되고 잦은 운 전과 정지가 이루어지며 충격, 소음 등의 외부환경 인자가 측정 데이터에 영향을 크게 미쳐 오차를 발생시킬 수 있다. 본 연구에서는 조선업의 내업공정에서 사용되는 갠트리 크레인의 Hoist 모사장비를 제작하여, 운전조건(RPM) 변화와 데이터 획득 센서의 위치 차이가 획득 데이터에 미치는 오차를 통계적으로 분석하였다. 연구결과 상대적으로 낮은 운전조건에서는 센서 위치 차이에 따른 획득 데이터 의 오차는 크게 발생하지 않았으나, 상대적으로 높은 운전조건에서는 획득 데이터의 오차가 크게 발생하는 것으로 확인하였으며, 회전 기계의 데이터 획득 시 운전조건과 획득 센서위치가 획득 데이터에 영향을 미치는 것으로 확인하였다.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization’s safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

The petroleum refinery industry handles a variety of complex chemical substances and employs a large number of people around the world. According to previous research, diseases caused by exposure to chemicals were quite common among workers in refineries until the 1980s. More recently, it is unusual for oil refinery workers to suffer from these serious diseases. The objective of this study was to identify the occurrence level of general diseases and any differences in lifestyle habits of workers in refineries in Korea compared with the general population. In this study, we used the results of health examinations from 2014 for workers at a large oil refinery in South Korea. In addition, based on the results of KNHANES from 2014 as representative of the population, hypertension, diabetes, anemia, hyperlipidemia, liver function abnormality, and kidney function abnormality were calculated using the standardized incidence rate. Hypertension showed a low result with an SIR of less than 1, but a high result in the case of abnormal liver function. The workers’ occurrence rates of hypertension, hyperlipidemia, kidney dysfunction, and anemia were lower than those of ordinary salaried employees. however, their occurrence rate for abnormal liver function was markedly higher. In lifestyle habits, the smoking rate of workers was low while the alcohol consumption rate was quite high. This study has improved the understanding of the health status of workers in a large oil refinery in Korea, and has shown the impact of lifestyle habits related to the work environment on chronic diseases.

본 연구는 사업장 보건관리자의 우수한 보건관리 활동과 동기를 파악하여 추후 보건관리자의 활동에 대한 가이드를 제시하기 위한 연구이다. 본 연구는 5년 이상 동일한 사업장에 근무한 사업장 보건 관리자 21명을 대상으로 연구에 대한 동의를 얻은 후 반구조화된 설문지를 이메일로 보내 자료를 수집하였으며 응답한 내용을 질적 분석하였다. 본 연구 결과 17개의 범주와 3가지 주제가 도출되었다. 도출된 주제 는 보건관리자로서의 보람과 성취감, 보건관리자로서의 어려웠던 부분, 어려움은 이렇게 해결하자이었다. 보건관리자는 근로자가 마음을 열어주고, 생활을 변화시키기며, 감사해 하며, 새로운 분야를 개척하는 것에 보람과 성취감을 느낀다고 하였다. 반면, 예측할 수 없는 건강, 조직문화의 변화, 질병을 비밀화하는 것, 보건관리자 업무가 편하다고 생각하는 사람들에 대해 어려움을 느꼈다. 이러한 어려움을 극복하는 방법으로 근로자의 마음을 읽어주고, 스스로 알게 하며, 기존 프로그램을 활용하며, 가장 어려운 사람을 내 편으로 하며, 자신의 성과를 알리는 것이 필요하다고 하였다. 본 연구 결과를 통하여 보건관리자는 자신의 전문성을 갖추기 위하여 노력하고, 건강관리 성과를 지속적으로 알려 사업장의 정책결정자와 근로자들에게 보건 관리의 중요성을 설득할 필요가 있다. 또한, 우수한 보건관리자의 성공전략을 적극적으로 벤치마킹해야 할 것이다.
