This study examined the effect of valence for best reply on the conformity of general reply in online environment. A total of 194 participants participated in this study, each participant assigned randomly in three experimental groups(positive, negative, and control). Participants were asked to read online news article, best reply and general 6 replies, and then, to write their own opinions in the reply section. In addition, the level of self-expression and issue commitment were measured. The contents of reply participants written was categorized three valence(positive, negative, and neutral) by the four experimenters' judgment. The mean of inter-rater reliability was 84.9%. The results indicated that the level of self-expression and issue commitment were comparable across experimental conditions. However, the result of cross-table analysis showed that there is a significant difference in the valence of general reply across experimental conditions. Specifically, there were significant difference in the valence of general reply between positive and negative experimental group and positive and control group, but there is no significant difference between negative and control group.

The effect of behavior based safety(BBS) program on safety climate and safety behaviors: A field study Kwang-su Moon Kye-hoon Lee Jae-hee Lee She-zeen Oah Chung-Ang University This study examined the effectiveness of behavior-based safety(BBS) program in improving safe behaviors and safety climate of organization. BBS program was applied to the steel manufacturing and construction sites. The dependent variables were measured the percentage of employees' safe behaviors observed and perceived safe behaviors and safety climate of employees. BBS program consisted of goal-setting, feedback,and incentive. The one group pretest-posttest design was adopted for perceived safe behaviors and safety climate. Observed safe behaviors were measured during the baseline and intervention phases(AB design).The results indicated that the mean percentage of employees' safe behaviors observed increased after introducing BBS program. Also, the mean scores of perceived safe behaviors and safety climate of employees significantly increased. Based on these results, the implications of this study and suggestions for future research were discussed.
