This study aims to predict return-to-work outcomes for workers injured in industrial accidents using a TabNet-RUSBoost hybrid model. The study analyzed data from 1,383 workers who had completed recuperation. Key predictors identified include length of recuperation, disability grade, occupation activity, self-efficacy, and socioeconomic status. The model effectively addresses class imbalance and demonstrates superior predictive performance. These findings underscore the importance of a holistic approach, incorporating both medical and psychosocial factors.

This study attempted to provide implications by analyzing the impact of business Owner’s safety commitment on industrial accidents and examining the mediating role of management supervisors’ safety leadership and worker participation. Analysis was conducted on 2,067 manufacturing sites with 20 to 50 employees in the 10th Occupational Safety and Health Survey data. SPSS waw used to secure the reliability of the measurement variable. Hypothesis vertification was carried out after securing the suitability and validity of the structural model using AMOS. The direct impact of three latent variables on industrial accidents was confirmed: the business owner’s safety commitment, the management supervisor’s safety leadership, and the worker participation. The employer’s safety will and the management supervisor’s safety leadership do not directly affect industial accidents, but it has been verified that worker participation has a diret impact on industrial accident reduction. In addition, it has been confirmed that the safety leadership and worker participation of the management. Supervior have a complete mediating effect on the reduction of industrial accidents by mediating with the safety leadership of the management supervior and the participation of the workers. This study analyzed the impact on industrial accidents by dividing the stakeholders constituting the workplace into three classes: business owners, superviors, and workers, but the results suggest that employers and all workers inside the workplace may be organically linked to achieving the goal of reducing industrial accidents. Therefore, in order to establish an autonomous safety management system for safety and health at workerplaces, efforts are needed to reduce industrial accidents in their respective location by forming an organic community among internal stakeholders.

Recently, the crisis of demographic extinction is rising in Korea more than any other country, and it is difficult for industrial sites to maintain without 'foreign workers'. Industrial accidents and accident deaths of foreign workers account for 7.6% and 12.3% of the total, through an in-depth analysis of fatal accidents in the manufacturing industry, differences and similarities between fatal accidents of foreign workers and all fatal accidents were confirmed in terms of occurrence type, workplace size, length of service, employment type, etc. In this study, customized countermeasures were found.

목적 : 본 연구는 직업복귀프로그램에 참여한 산업재해근로자를 대상으로 원직무복귀에 미치는 요인을 알아 보고자 하였다. 연구방법 : 2014년 11월부터 2016년 8월까지 경상남도 소재의 C병원에서 직업복귀프로그램에 참여한 산업 재해근로자 92명을 대상으로 인구사회학적 요인, 산업재해관련 요인, 직업관련 요인, 직업복귀프로그램 요인들이 원직무복귀에 미치는 효과를 분석하였다. 결과 : 산업재해근로자의 원직무복귀에 미치는 요인을 분석한 결과 인구사회학적 요인에서는 나이, 산업재해 관련 요인에서는 산업재해요양기간, 통증, 직업관련 요인에서는 고용형태, 작업강도, 직업복귀프로그램 관련 요인에서는 작업능력평가 결과, 작업능력강화프로그램 시작시기가 상관관계가 있었으나 적용기간은 상관관계가 없었다. 결론 : 본 연구는 산업재해근로자들이 나이가 적고, 산업재해요양기간이 짧고, 통증이 적을수록, 고용형태가 정규직이거나 작업강도가 낮을수록, 작업능력평가결과가 좋거나 직업복귀프로그램 시작시기가 빠를수록 원직무복귀를 높일 수 있음을 지지하였다.

This study is analyse method for Industrial disester prevention of E-9 foreign workers. To do this, We adapted tp TRIZ 's creative problem solving theory and AHP, QFD. TRIZ is determined some parameters for problem solving and selected the inventive principles for each parameters. So, We made new parameters and inventive principles under theory of the TRIZ process for reduced to the foreign worker’s disaster rate. After, The derived parameters and the inventive principles are used to evaluate the importance of factors through the AHP, and determine the weight of the relation through QFD expansion. Finally. this paper applies statistical data according to the determined model process, analyzes the result and proposes improvement method for the prevention of disaster of foreign workers

목적 : 본 연구는 산재근로자를 대상으로 작업능력강화프로그램이 자기효능감, 우울, 재활동기에 미치는 효 과와 원 직무복귀에 따른 그룹 간 차이를 알아보고자 하였다. 연구방법 : 2015년 6월부터 2016년 8월까지 경상남도 소재의 C병원에서 작업능력강화프로그램을 실시한 산재근로자 49명을 대상으로 실시하였다. 작업능력강화프로그램은 1일 1회 3시간 이상 주 5회, 총 4~8 주간 실시하였고, 프로그램 중재 전･후 자기효능감, 우울, 재활동기를 측정하였다. 산재요양기간 종료 후 2개월 뒤 추적관찰을 통해 원 직무복귀 그룹과 원 직무복귀 실패 그룹을 나누어서 두 집단 간 차이를 알아보았다. 결과 : 작업능력강화프로그램 실시 후 자기효능감, 우울, 재활동기에서 유의한 차이가 있었다(p<.05). 산재 요양기간 종결 2개월 뒤 원 직무복귀 여부에 따라 두 집단 간 차이를 확인했을 때 자기효능감의 변화량 에서 유의한 차이를 보였다(p<.05). 결론 : 본 연구는 작업능력강화프로그램이 산재근로자의 자기효능감, 우울, 재활동기 향상에 효과적임을 보 여주었고, 자기효능감이 원 직무복귀 성패에 중요한 요인임을 제안한다.

Analyses were performed with Rosenberg Self-esteem Scale. The population was 1,391 Korean workers in total. Subjects who get scores of self-esteem lower than those before the accidents were 539 people(42.34%). On the other hand, subjects who get the same or higher scores of self-esteem than those before the accidents were 802 people(57.66%). The average score of the whole showed 30.09 point that is higher than 29.99 points that were analyzed from primary panel data. The odds ratio of self-esteem is analyzed to find that what is the most important factor for improving self-esteem of the workers group. The result of odds ratio analysis was 1.60 in the not-to-return-to-work group, significantly higher of the score of self-esteem than the return-to-work group. The statistically significant odds ratio of unemployed workers group from the group of workers who return to work prove the academically conventional social norms. This result shows that the workers condition, whether or not they can return to their work, affects the workers‘ self-esteem. Therefore, the workers' condition for returning to the work should be considered the most important service for Korean workers' compensation and welfare services.

This study was designed to analyse the performance and the mechanisms of workers' participation and communications in industrial accident prevention activities leading to the reduction of industrial accidents. This study also aimed to find out the causal relationship influencing the promotion of prevention activities of industrial accidents. Of the manufacturing businesses with more than 5 workers as the population of the survey, a questionnaire was conducted with 2,500 workspaces chosen by stratified sampling. Out of 2500 workspaces, 971 workspaces equipped with industrial safety and health committee were analysed in this study. According to the results of this study, the primary influential factors on safety activities were the management of industrial accidents and the cooperations between supervisors and workers on site. The secondary influential factor was the establishment of industrial safety and health committee. Regarding the effectiveness of industrial accident reduction, -0.01 was shown by workplace safety activities by themselves and -0.09 was shown by participation and communications through indirect safety activities. This indicated workers' participation and communications play an important role in the reduction of industrial accidents. By discovering the clue to the mechanism of the workers' participation and communications, this study is expected to stimulate the reduction of industrial accidents by emphasizing the importance of workers' participation and communications in resolving the safety and health problem in the workplaces.
