Abstract

This study is intended to provide basic data regarding necessity of chamber utilization for work performance of industrial divers with focus on correlation between chamber usage and the performance. In order to effectively achieve the goal, some of occupational divers residing in South Kyungsang province or P Metropolitan City were selected as research target using a convenience sampling. For a preliminary research, a pilot test was conducted on 100 industrial divers, who submitted 302 final survey papers with questionaries of proven reliability and validity. The collected questionaries were analyzed using the SPSS 14.0 Program and verified through T-Test and One-Way ANOVA for analysis of frequency, reliability, exploratory factors, technologies, correlation, and verification of discrepancy, which was backed up with post-verification through Duncan Test. Next, a multi-regression analysis was conducted to look at the effects on the work performance, followed by analysis of tolerance limits and variance inflation factors to determine the regressive multi-collinearity, and the Durbin-Waston Test to verify the self-correlation, which produced the following results. First, the T-Test based on personal attributes, certificate acquisition status, and chamber utilization experience showed divers holding certificates were well-aware of the effects of chamber satisfaction, and those actually using it were well-aware of chamber satisfaction, chamber utilization satisfaction, and non-financial effects. In addition, industrial divers using chambers were well-aware of process satisfaction and financial effects. Second, the One-Way ANOVA based on personal attributes, age, educational level, work experience and monthly income showed that divers in their 40s showed a bigger discrepancy in awareness of chamber satisfaction, chamber utilization satisfaction, process satisfaction, financial effects and non-financial effects than any other groups. In terms of educational level, high school, junior college, and 4-year university graduates showed a big discrepancy in awareness of process satisfaction and financial satisfaction. As for work experience, all groups except those with one year of experience or less showed a big discrepancy in awareness of chamber satisfaction, chamber utilization satisfaction, financial effects and non-financial effects. Regarding monthly income, those earning at least 9 million a month showed a big discrepancy in awareness of chamber satisfaction, chamber utilization, and financial effects, and those earning 7 to 9 million Won showed a big discrepancy in awareness of non-financial effects, whereas those earning less than 3 million Won showed a discrepancy in awareness of process satisfaction. Third, the multi-regression analysis conducted to verify the correlation between chamber utilization, and financial and non-financial effects showed that chamber utilization satisfaction and process satisfaction had a positive effect on the financial and non-financial effects, whereas chamber satisfaction factors were not related to those effects.
