In the recent era of the fourth industrial revolution, many industries aim to maximize the efficiency of products and services by introducing cutting-edge technologies such as artificial intelligence and big data. In this situation, organizational culture is changing a lot due to the influx of the MZ generation with strong individualistic tendencies and the decreased face-to-face communication between members. However, active communication with colleagues is still essential to maximize performance, and the margins created by simplifying work processes and automating processes must be used for creating work performance. This requires cooperation and commitment through the job immersion of members who have an active attitude. This study analyzed how the organization's autonomous work environment and trust among members, which are creative work performance conditions, affect job immersion using raw data from the Occupational Safety and Health Research Institute. As a result, it was found that both the organization's autonomous working environment and trust among members significantly effected the members' job immersion. in order to achieve productivity and value improvement in companies, efforts are needed to increase workers' job immersion by building an autonomous working environment and trust among members. The results of this study are expected to contribute significantly to the search for ways to increase workers’ job commitment to improve organizational productivity.

In addition to physical risks such as electrical, chemical, and mechanic ones in the workplace, psychosocial risks are also raising as an important issue in recent years in connection with human rights and work-life balance policies. The purpose of this study is to confirm the degree of effect of the psychosocial risk management plan at the workplace on workers through logistic regression analysis. Input data for logistic regression analysis is the results of a survey of 4,558 people conducted by the Institute for Occupational Safety and Health were used. There are 9 independent variables, including the change a workplace and confidential counseling, and the dependent variable is whether the worker feels the effect on the psychosocial risk management plan. As a result of this study, changes in work organization, dispute resolution procedures, provision of education program, notification of the impact of psychosocial risks on safety and health, and the persons in charge of solving psychosocial problems are shown effective in reducing worker’s psychosocial risks. This study drives which of the management plans implemented to reduce the psychosocial risk of workers in the workplace are effective, so it can contribute to the development of psychosocial risk management plans in the future.

목적 : 본 연구는 지체장애 근로자의 근로환경인 장애인 편의시설과 편의제공 현황을 살펴보고 이에 따른 직무만족도의 차이와 장애인 편의시설과 편의제공이 지체장애 근로자의 직무만족도에 미치는 영향을 알아보고자 한다. 연구방법 : 본 연구는 2018년 한국장애인고용공단에서 실시한 2차 웨이브 3차 장애인고용패널조사 원자료를 활용하여, 3차 조사 당시 임금근로자로 종사하고 있는 지체장애인 927명의 자료를 최종적으로 분 석하였다. 본 연구에 필요한 문항만 선별하여 독립표본 t-검정과 일원배치 분산분석, 다중회귀분석을 실시하였다. 연구결과 : 지체장애 근로자의 성별 연령, 학력, 장애형태에 따라서 직무만족도에 유의한 차이가 나타났고, 장애정도에 따라서는 유의한 차이가 없는 것으로 확인되었다. 장애인 편의시설은 5개 항목 전체에서 설치되어 있는 경우 지체장애 근로자의 직무만족도가 유의하게 높았다. 편의제공은 근무시간 조정, 업무 수행 시 타인의 도움, 작업에 대한 지도 및 직장생활 상담, 장애인 편의시설 설치 항목을 제공 받은 경우 직무만족도가 유의하게 높게 나타났다. 지체장애 근로자는 장애인 편의시설의 개수가 증가할수록, 편의제공 개수가 증가할수록 직무만족도가 유의하게 높아지는 것으로 나타났다. 결론 : 장애인고용패널조사 빅데이터 분석결과를 통해 지체장애 근로자의 근로환경의 중요성을 확인하고 지체장애 근로자의 직무만족도 향상을 위해 직업재활 분야 전문가의 필요성을 확인할 수 있었다. 본 연구 결과는 작업치료사의 직업재활 업무 수행에 기초자료로 활용될 수 있을 것이다.

본 논문에서는 산업안전보건연구원에서 실시한 제 4차 근로환경조사(2014) 원시자료를 활용하여 서비스 종사자들의 고용형태에 따른 근로환경 실태와 근무사기에 관하여 연구하였다. 근로환경 실태는 업무자세, 감정노동, 업무 자율성으 로 구성되어졌으며, 근로사기와 관련된 심리적 차원은 업무에서 느끼는 유능감, 직무만족, 사회적지지, 직무스트레스로 이루어졌다. 아울러 고용형태는 상용직, 임시직, 일용직 근로자를 중심으로 분류하여 분석하였다. 연구결과 상용직 근로자에 비해 임시직과 일용직 근로자들이 좀 더 열악한 환경에서 근무하는 것으로 밝혀졌다. 그러나 상용직 근로자들 의 감성노동에 대한 질적 피로도는 더 높은 것으로 추정되었다 뿐만 아니라 근무환경과 근로사기 간에는 밀접한 상관관계가 있는 것으로 나타났다. 본 연구를 토대로 서비스업 종사자들이 가지는 실태와 문제점에 대해서 알 수 있었으며, 좀 더 나은 서비스가 되기 위해 근로자들의 근로환경과 근무사기를 높일 수 있는 방안들에 대한 모색들이 이루어질 수 있으리라 기대된다.

This study is intended to look into the effects of employee's working environment on work loss and productivity in overseas construction sites of Korean construction companies. To achieve this, a survey was empirically carried out to overseas construction site experts. The results were as follows. The weight by 5 loss factors of overseas construction projects showed that project management environment was the highest, followed by construction company environment, owner environment, government support environment and entry country environment, which the biggest work loss factor was the project management section. The weight by loss factors of entry country environment showed that local environment was highest, followed by social environment, economical environment, political environment and cultural environment. In other words, awareness and management of weak social bases, which are not well-institutionalized as properties of most preferred loss, are important in that local environment of new entry countries is the most important thing. As for the above-mentioned findings, the most important project management of overseas construction projects will need to take advantage and have know-how for construction companies' ability to cope with a crisis or the most preferred management and loss prevention of owner environment, government support environment and entry country environment.

Decision Tree is one of analysis techniques which conducts grouping and prediction into several sub-groups from interested groups. Researcher can easily understand this progress and explain than other techniques. Because Decision Tree is easy technique to see results. This paper uses CART algorithm which is one of data mining technique. It used 273 variables and 70094 data(2010-2011) of working environment survey conducted by Korea Occupational Safety and Health Agency(KOSHA). And then refines this data, uses final 12 variables and 35447 data. To find satisfaction factor in working environment, this page has grouped employee to 3 types (under 30 age, 30 ~ 49age, over 50 age) and analyzed factor. Using CART algorithm, finds the best grouping variables in 155 data. It appeared that ‘comfortable in organization’ and ‘proper reward’ is the best grouping factor.

This study was planned to investigate the effect of the exposure to hazard factors on work environment satisfaction. Existing researches about job satisfaction have focused on the general working conditions, such as working hours, wage, human relationship, job task and so on. Korean Working Conditions Survey was used for this study because that relevant questions were included. The effect of the exposure to hazard factors on work environment satisfaction may be produced by hierarchical regression analysis because of comparison with existing model for work environment satisfaction. The exposure to hazards factors were statistically significant effect on work environment satisfaction after adjusting other confounding variables, such as gender, age, educational level, job security, work hour, work load, work autonomy, social support, etc. This study has some limitation because that KWCS was cross sectional survey. Some researches about the causal effect and its mechanism may be suggested as future study.
