Abstract

Abstract According to the Korea National Statistical Office data in 2008, the population over ages of 65 years would possess to 10.7% whole population of Korea in 2009 denoting Korea is already in the aging society. In addition, the office also expected that Korea would enter in the aged population over 65 years: 14.3% and post-aged 20.8% society in 2019 and 2026 respectively, and which suggests that an averaged age of workers in Korean industries may increase rapidly in future. Statistics support that suggestion in which the persons employed in Korea during last 10 years increased in the ages over thirties, forties, fifties and sixties by 0.3%, 40%, 47% and 49% respectively, while twenties decreased by 9.3%. In that regard, the main purpose of this study is to assess the work ability and the job stress of each age group in order to identity the influential factors on those items. To this end, Questionnaires about work ability and job stress were distributed to practitioners in shipbuilding industry and statistical analysis was performed to assess work ability and the job stress based on the responses from the practitioners. The results show no significant difference was identified on the effect of aging although working ability of some group(between 45 and 49 years) was a little higher than others. This suggests that the work ability in not necessarily related to aging of Korean society and this is not in accordance with the previous research. One possible explanation due to for this peculiarity may be different cultural characteristics of Korean society are reflected on the responses. On the other hand a significant difference according to the stress levels is identified in the effects on job stress. This suggests that stress level is one major influential factor on working ability. In summary, job stress has a significant effect on WAI scores even though aging did not have a significant effect on WAI scores.
