Abstract

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.
