본 연구는 여성근로자의 경력개발에 있어 조직의 지원과 경력성공 간의 관계를 확인하였다. 특히 이 연 구는 여성근로자 개인의 자기효능감을 중심으로 살펴봄으로써 조직의 지원이 인간의 배움력을 통해 경력 성공에 미치는 영향을 확인하였다. 이를 위해 한국여성정책연구원이 구축한 여성관리자패널조사의 2016 년 6차 조사 자료를 활용 최종 589명의 응답을 토대로 분석을 수행하였다. 연구결과 첫째, 조직 내에서 여성근로자의 경력개발을 위한 제도적 지원이나 심리적 지원을 제공하는 것이 구성원들로 하여금 업무에 대한 자기효능감을 향상시키는데 정(+)적 영향을 미치는 것을 확인하였다. 둘째, 조직의 제도적 지원, 조직의 심리적 지원은 직무만족에 정(+)적으로 유의미한 영향을 미치고 있음을 확인하였다. 셋째, 조직의 제도적 지원, 조직의 심리적 지원이 조직몰입에 미치는 영향을 확인한 결과, 경력개발을 위한 조직차원의 심리적 지원과 조직몰입 간의 관계에서는 통계적으로 유의미한 영향이 발견되지 않았다. 넷째, 조직구성원의 자기효능감과 직무만족 간의 관계에 대해 확인한 결과, 이들 간의 관계에 정적으로 유의미한 영향이 있는 것을 확인하였다. 마지막으로 자기효능감, 직무만족이 조직구성원의 조직몰입에 미치는 영향을 확인 한 결과, 자기효능감과 직무만족 모두 조직몰입에 유의미한 정적 영향을 미쳤다. 이 연구는 조직 내에서 지속적으로 경력개발을 할 수 있도록 지원하는 원인변수인 교육훈련에 대한 제도적 지원과 상사의 심리적 지원이 자기효능감과 직무만족을 통해 주관적 경력성공인 조직몰입에 미치는 영향을 확인하였다. 이를 통 해, 여성근로자의 경력이탈에 대한 문제인식이 커지는 현 상황에서 구성원의 경력성공을 지원하기 위한 기업의 지원 방향 설정에 도움이 되기를 기대한다.

This study is intended to research workers’ health, diet and the demand of nutrition education service in Seoul and Gyeonggi-do province. We implemented the survey from September 2012 through August 2013, and analyzed the data from 589 workers’ questionnaires out of 890. For the analysis of the compiled data, we utilized the SPSS version 18.0 statistical package program. The study showed that majority of the workers participated in the survey consisted of 447 male (75.9%) and 142 female (24.1%). BMI showed that these men were overweight (24.5±2.72) and women were normal weight (22.2± 2.70). Participants often diagnosed with hypertension or hyperlipidemia. In terms of health status, 34.5% answered satisfactory, the most concerned illness was high blood pressure, and the bad eating habits were often associated with general overeating and excessive intake of salt. 65.5% of participants had a meal three times per day. 49.4% of male participants had a meal less than 15 minutes and 66.2% of female participants had a meal between 15 and 30 minutes. The average of workers who needed to nutrition education is 3.74+0.85. The most desired way of learning was through counseling (36.7%), with overweight and weight management identified as the most interested topics. A relatively high portion (80%) passed the nutrition knowledge assessment test. According to the survey the highest rate of full-time employment is 85.2% which showed in small work places (the number of people on meal plan was 100~300), however the lowest rate of full-time employment showed 70.0% in large workplaces (the number of people on meal plan was within 1,000).

While Korea had achieved radical growth of construction industry, it also had accumulated problems in material, human and economical loss due to its low quality of safety level. Therefore, not only enterprises but also the nation is putting in a great deal of efforts for construction safety. However, its effect is not satisfiable. This research aims for change of construction cite by introduction of professional Safety Patrol Management System(SPMS) and consideration of its necessity. To consideration of its necessity, we compared and anaylzed average numbers of indicated dangers and safety accident incidences in each construction cites and we researched changes in worker's safety sense. It will establish the suitable design standards and suggest the basic database for estimating disaster and accident ratio.

The occupational injury and illness(OII) was influenced by the various factors. This study was planned to investigate the pathway of the activities of OSHM on the rate of OII via worker's participation. The survey on the trend of the activities of OSHM was used. The sample size of manufacturing industry was 3,000 enterprises and that of construction was 1,000 enterprises. The survey was done by interview method with structure questionnaire. Questions about the activities of OHSM were integrated into one category using factor analysis. The enterprises with OII has more activities of OSHM than that without OII. Among enterprises with OII, the level of the activities of OSHM was positively correlated with the rate of OII. The activities of OSHM has influenced on the rate of OII directly and indirectly via worker's participation and the activities of prevention of accident. Worker's participation also has the direct effect and indirect effect on the rate of OII. Worker's participation in construction sector has more effect on OII than that in manufacturing sector.

Based on a literature review regarding shift work, it is recognized that it has an adverse effect on workers' health. Especially, the night shift rather than the day shift imposes severe disorders on workers, which are indicated to dyssomnia, maladaptation to social life, and health problems such as gastroenteric trouble, cardiovascular diseases and depression. As the shift work can be explainable by using workers' labor ability necessarily to maintain company business consistently, it does not consider biorhythm, active mass and health condition of workers Actually duration of shit work would deprive workers of fundamental life rights by causing physical and mental effects. As a result of reviewing previous case studies related to effect of work pattern (day shift and night shift) on workers' health, an incidence of physical diseases like dyssomnia, gastroenteric trouble, cardiovascular diseases and premature delivery was higher in shift workers than normal workers. Additionally the incidence of mental disorders such as busy brain, social isolation, depression and work stress was also higher in shift workers than normal workers. These adverse physical and mental problems were intensified to night shift workers compared to day shift workers. Considering current various reports and study results, it is recommended that the shift work, especially the night work pattern, should not apply to contemporary work situation for sustaining workers' health condition constantly.

Currently, in Korea, an accident that takes place during a worker's commuting is generally not considered as work-related accident. However, there are several exceptions such as an accident that occurs in commuting while using transportation provided by an employer, an accident that happens during commuting time that can be regarded as part of a business activity (e.g. tending to work instructed by an employer on the way to or from work), and an accident that is caused by insufficient facility management by an employer. It is even more so as the workers' commuting distance increases with expanding scale of a city, and traffic accident occurs more frequent. Social risk of commuting-time accident is on the rise. Under this circumstance, it is an important social issue to explore how to protect workers from commuting-time accident.

The psychosocial stress and musculoskeletal disorders(MSDs) have been one of major health problems for hospital workers. This study tried to understand the relationship between symptoms associated with MSDs and risk factors such as working posture, job stress, psychosocial stress and fatigue. A total number of 655 hospital workers participated in this study. Specifically, REBA was applied for evaluating working posture and a checklist prepared by KOSHA(Korean Occupational Safety and Health Agency) was used for symptom survey. A questionnaire from KOSHA was also used for collecting data associated with job stress, psychosocial stress and fatigue. All these data were formulated and modeled by path analysis which was one of major statistical tools in this study. Specifically, path analysis for the data we collected came up with several major findings. As a result, as for body part(neck), (waist) and (arms) the degree of risk of work posture measured with the use of job stress(KOSS), psycho-social stress(PWI-SF) and REBA is significantly more affected by fatigue than muscular skeletal disease related consciousness symptom. However, regarding bod(wrist), the degree of risk of work posture measured with the use of job stress(KOSS) and REBA is directly affected by muscular skeletal disease related consciousness symptom. This study is meaningful in that the study clarified the causal relations of the degree of risk of work posture, degree of fatigue, and muscular skeletal disease related consciousness symptoms by each body part measured with the use of work stress(KOSS), psycho-social stress(PWI-SF) and REBA.

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.

For the past 25 years, Korean semiconductor has experienced enormous growth to be the highest production country in the world. Semiconductor industry is very time sensitive and driven by technology and process, and requires 24-hour full operation. The environment includes many different types of equipment, utilities, different gases and toxic chemicals as well as high voltage electricity. We have performed a survey with 3-shift engineers and workers in one line. The content of the questionnaire was about the correlation between fatigue and performance shaping factor (work type and work ability), and as a result we were able to deduce the correlation, p-value and the pattern of scatter plot. The shape of the model was made of 4 blocks for fatigue, 5 blocks for work type and 5 blocks for work ability, i. e. 14 blocks in total. As a conclusion to this findings, there was a correlation between fatigue and work type and work ability specifically in semiconductor industry, and we need some effort to reduce this.
