The current study examined the relationships between disaster victims' post-trauma risk and posttraumatic growth, and the mediational role of social support for this relationships. In addition, we tested the hypothesis that income status would moderate the relationship between post-trauma risk and subjective well-being. Two hundred disaster victims completed Post-trauma Risk Checklist (PRC), Posttraumatic growth scale, Social support scale and Concise Measure of Subjective Well-Being (COMOSWB) as well as questions about their demographic characteristics. Results showed that those with high post-trauma risk demonstrated significantly higher levels of posttraumatic growth as compared to those with low post-trauma risk and social support partially mediated this relationship. Also, high levels of post-trauma risk predicted low levels of recent subjective well-being. Participants with high income obtained higher subjective well-being than did those with low income among high post-trauma risk groups. Implications for post-trauma risk and posttraumatic growth are discussed.

The purpose of this study is to examine the effect of subjective overwork on health and the moderating effect of risk perception in the relationship between subjective overwork and health. The data used in this study are the fourth Korean Working Condition Survey (KWCS) conducted by Korea Occupational Safety and Health Agency (KOSHA) in 2014. The items related to actual working hours, subjective overwork, health, and risk perception were used. A total of 18,508 workers who are 1) waged workers, 2) work more than three days a week, 3) work more than 21 hours a week, 4) work longer than preferred work hours or work as longer as they desired were selected. Hierarchical regression analysis was performed to identify the effect of actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage on health and to determine the moderating effects of prevalence of risk and lethalness of accident damage. As a result, actual work hours, subjective overwork, prevalence of risk, lethalness of accident damage had an effect on worker's health problems. Second, lethalness of accident damage had a moderating effect in the relationship between subjective overwork and health. These results suggest that organizations should manage worker's environmental factors and other threats that could increase the lethalness of accident damage.

The assesment of the safety of ship's transit in a curved narrow channel consists of the maneuvering safety determined by the chance of running aground, the maneuvering difficulty determined by ship's workload, and shiphandler's subjective evaluation. In this study to examine the correlation between shiphandler's subjective evaluation and the maneuvering risk, the real-time and full-mission shiphandling simulator in the Korea Marine Training & Research Institutes(KMTRI) was utilized. On the conning bridge of the shiphandling simulator, 50 experienced masters conducted the modeled vessel of 60,000 deadweight tonnage along the designed channel under 3 different environmental conditions. The findings were as follows : (1) The frequencies of stress levels, work difficulties, vessel controllability and overall workload of shiphandlers are similar irrespective of environmental conditions and they are able to be represented as shiphandler's subjective evaluation. (2) It s possible to assess and analyze theoretically the correlation between the shiphandler's subjective evaluation and maneuvering risk under each environmental condition by quantifying the data obtained from the test. The results are as follows : ① As the degree of maneuvering risk increases, the shiphandler's subjective evaluation increases sharply near the curvature area of the designed channel. ② In the area of the curvature of the designed channel, maneuvering risk sincreases sharply with the danger of running aground under the environmental condition of current and wind coming from the stern.

The purpose of this study was to investigate the effect of perceived risk and product express-ive self-image on the consumer's adoption of casua hanbok. A questionnaire was developed and data colle-cted from 269 women in Pusan. Data were analyzed to investigate the relation-ship among purchase intention perceived risk and product epressive self-image. Marketing implication about risk reduction was discussed. The results of this study were as follows. 1. Consumer's perceived risk on adoption o casual hanbok classified into four factors They were the risk on the confirmation of advantage of casual hanbok the risk on the negative viewpoint of others the risk on the complexity of dressing and care and the risk on the shortcoming of casual hanbok. It was explained that casual hanbok is innovative product. 2. According to the level of adoption of casual hanbok. consumers were categorized into three groups i.e. adopter potential adopter rejector. They differed in the degree of risk perception age and subjective knowledge redlated to casual hanbok. 3. Consumer's subjective knowledge age and two types of risk has predicting power to the purchase intention. Consumer's subjective knowledge was the best predicted factor and risk perception was negatively related to purchase intention. 4. The significant differences among the categ-orized consumer group was founded in the ideal self image and product expressive self-image 5. The gap of perception between ideal self-image and product expressive self-image was significantly different in each categorized consumer groups.

Considering about construction projects characteristics, there Is an existing uncertainty which causes inaccuracy or invalidity under decision making situation. Therefore, cost risk analysis of numerous construction projects are Inclined to depend on expert's experiences and subjective judgements. In Korean domestic construction works, however, there is no reasonable method or process for applying subjective elements. Only probabilistic analysis using objective calculation are being used now. This research suggests a cost risk analysis method to analyze quantitatively Cost Impact by risk, and it appraises expert's subjective elements for the purpose of enhancing validity of cost estimation. Moreover, a new cost risk analysis method is introduced for providing convenient user interface in practical business.
