원자력발전소 건설 종사자의 작업능력과 직무스트레스에 관한 연구

Abstract

According to this plant construction trends, the future plant construction will be very complex, specialization and oversize, so it is expected that future plant construction will create high-profits and require the connection between high-technology and construction method. To catch this advance, more detail business management plan and knowledge sharing technology are needed as basic element. In aged society, to keep the work ability in aged population is an important issue because of a gradual decrease of working population. According to the Korea National Statistical Office data in 2009, the population over ages of 65 years would possess to 11.0% whole population of Korea in 2010 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. 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 plant construction 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 50 and 54 years) was 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. 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.
