근로능력은 장애인소득보장정책과 장애인고용정책에서 정책대상자를 선정하는 핵심요인이다. 우리나라에서 사용하고 있는 근로능력평가지표인 장애등급은 의학적 손상에 기초하여 결정되는 것으로, 제대로 근로능력을 평가하지 못한다는 비판을 받고 있다. 이 연구에서는 장애등급, ICF 활동참여수준, 일상생활도움필요정도 및 자기평가건강상태의 4 근로능력평가지표들이 장애인의 취업여부에 대한 설명력을 비교함으로써 가장 적절한 평가지표를 찾아 내고자 하였다. 그 결과, ICF 활동참여수준이 장애인의 취업여부에 대한 설명력이 가장 높았으며, 이어서 일상생활도움필요정도, 장애등급, 그리고 자기평가건강상태의 순으로 나타났다. 결론적으로 장애인연금제 및 장애인고용정책 등에서 적절하게 활용할 수 있는 근로능력평가지표는 ICF 활동제한 및 참여제약 영역에 해당하는 지표들이라고 할 수 있다. 따라서 ICF 활동제한 및 참여제약 영역을 바탕으로 한 근로능력 평가지표가 장애등급보다 더 적절한 근로능력평가지표라고 할 수 있을 것이다.

Purpose: The purpose of this study was to learn the affective factors of case managers' occupational stress. Method: A total of 986 participants responded to a self-administered questionnaire that included 24 items of Korean Occupational Stress Questionnaire Short Form (KOSQSF), job satisfaction index, health behaviors, general characteristics, and variables related to work. The data collection of research was done from 17th to 21th of September, 2007. The data were analysed by t-test, ANOVA, and multiple regression with SPSS 11.1 package program. Result: The results of this study were as follows: The overall job satisfaction rate of men and women was highly than that of the Korean worker's standard. There were statistically significant differences in occupational stress in work place, work department, work position, smoking, treatment in out-patient clinic, subjective & relative health-status, work load, supervisor's review on work-ability, and job satisfaction. According to the multi-variate analysis, occupational stress(47.6%) was related to job satisfaction, workload, individual work-ability, supervisor's review on work-ability, health status and gender. Conclusion: Occupational stress varied depending on the ten variables and was influenced by job satisfaction(35.7%) and 5 other variables. The results suggest that further follow-up study on case managers is necessary to relieve their occupational stress.

According to the Statistics Korea, in 2011, people over the age of 65 years old accounted for 11.8% of Korea's population. This number is expected to rise to 15.0% by 2019, making Korea an "aged society". As age increases, physical ability degrades to the point that the workload must be adjusted limitations. However, workloads are given regardless of workers' ages or abilities. In addition, a decline in work efficiency due to aging also increases the risk of work-related injuries. Furthermore, the cases of stress related diseases along with musculoskeletal disorders(MSDs) rise as main factors of industrial disasters and excessive job stress gives negative influence not only on mental health but also on physical health so that job stress becomes a hot issue as a main cause of work ability falloff and turnover. The purpose of this research is to examine how the sociodemographic characteristics, MSDs symptoms and musculoskeletal workload of workers in the manufacturing industry of automobile parts influence work ability and job stress. As a result of the research, job ability showed significant differences statistically according to age, working year, sex, marital status and musculoskeletal workload and job stress showed significant differences statistically according to age, working year, marital status and musculoskeletal workload. In addition, it showed that as the worker's job ability decreases, job stress increases.

Purpose: The purpose of this study was to test the reliability and the validity of the Practice Environment Scale of Nursing Work Index (PES-NWI) scale when applied to Korean psychiatric nurses working in the psychiatric hospital in Korea. Methods: Data from 224 psychiatric nurses working in the 6 psychiatric hospitals in Korea were analyzed using Cronbach's ${\alpha}$, item total correlation, and exploratory factor analysis. Results: The Cronbach's ${\alpha}$ for the 27 items from the PES-NWI were .93, and the item total correlation coefficients ranged from .38 to .64. Six factors which explained 61.2 of variance in the perception of practice environment, emerged; nurse professional role and development, nurse manager ability, leadership, and support of nurses, staffing and resource adequacy, nursing foundation for quality of care, collegial nurse-physician relations, co-worker's ability and qualification. Five derived factors reconstructed, and two factors were renamed. Conclusion: Findings demonstrate that not all but 27 items from PES-NWI is a reliable and valid scale when applied to Korean psychiatric nurses working in Korea. Also findings indicate that Korean psychiatric nurses perceive practice environment differently than American nurses but have some point of similarities with Asian nurses working in the United States.

The increasing prevalence of inactivity and obesity, along with aging, has implications on work capacity of labor force. This study reports the relationships between activity level and BMI by age with objectively measured physical workload. Data were examined from a sample of 19 481 Finnish employees using an estimate of minute-to-minute oxygen consumption based on R-R interval recordings. The mean estimated %VO₂max during the working day was 12.1 (±3.6) and 15.1 (±4.5)% for men and women, respectively. Based on a linear model, the mean %VO₂max increased by 1.5%-unit per 10-year increase in age, by 2.1%-unit per 5 kg/㎡ increase in BMI, and decreased by 1.6%-unit if improving physical activity class by two (p < 0.001 for all). Overweight and obesity, together with inactivity, notably increases workload throughout the career, even though at young adulthood, the daily workload is almost the same for each person regardless of the BMI, activity level, or gender. This study highlights the importance of regular physical activity and normal weight in protecting the worker from excessive physical (cardiovascular) workload during the whole working career.
