The success of construction projects is heavily dependent on the work ability of the field managers who manage the execution of projects. The work ability of field managers is influenced by various elements such as job stress and individual characteristics. The purpose of this study is to reveal the factors influencing the work ability of construction field managers in Korea. Work ability is evaluated bases on the Work Ability Index(WAI) developed by the Finnish Institute of Occupational Health, while job stress is measured using the Korean Occupational Stress Questionnaire Short Form developed by the Korean Occupational Safety & Health Agency. The results showed that field managers under higher job stress have lower work abilities. In addition, it is revealed that exercise or religious practice have a positive influence on work ability. This study will help to increase the work ability and enable the efficient management of organization at building construction sites.

This study is to look into the effectiveness of fall-preventive occupational therapy of elderly by clarifying the influence of occupational therapy applied to female elderly in the community upon balance ability. A 6-week occupational therapy program including both training and exercise for prevention of fall down was applied by dividing into 13 persons of experimental group and 13 persons of control group for female elderly aged more than 65 years who were capable of independence gait and have not taken any drug to adversely affect balance. For balance ability assessment, the Berg balance scale and the Tetrax fall index were used. The Berg balance scale in experimental group was shown to be 48.38 to 50.69 through the 6-week program, indicating changes in significance level(p=.017). The Tetrax fall index in experimental group was shown to be 46.77 to 35.54 through the 6-week program(p=.000). Changes in significance level were not found for both the Berg balance scale and the Tetrax fall index in control group. As seen from the results of this study, it is found that 6-week application of the fall-preventive occupational therapy program including fall prevention training and exercise was effective for promotion of elderly's balance ability, and further studies just on the effect of fall prevention training are required to be made.
