We investigate how smokers and drinkers have influenced on self-reported risk assessment and workplace injuries, using the Korean Working Conditions Survey. Our empirical results indicate that persistent smoking habit raises workers' job risk assessments and work injuries significantly. Also, former smokers notice relatively higher risk assessments in various work activities, but they are less likely to affect work injuries. More frequent drinking behavior leads to a positive effect of job risk perception and workplace injuries. Regular smoking with frequent drinking for high income classes, however, have significantly reduced the chance of work injuries. Furthermore, establishing smoking-designated area at the workplace makes workers reduce workplace accidents positively. Therefore, the network effect of smoking and drinking behaviors in private circle levels is suggested to extend into public and constructive activies at the workplace levels for sharing useful and productive information, which will eventually reduce workplace injuries dramatically.

A compact ESP of two-stage type is widely used with positive corona discharge in working environment where the production of ozone is extreamly prohibited. Since there are few scientific reports on a compact ESP, we have investigated the fundamental characteristics of a two-stage ESP. A model two-stage ESP is made with simple structure in order to simplify theoretical analysis and the relative position of the ionizer and collector section can be changed. The experimental investigation revealed many interesting facts.: The electric field in the collector electrodes affects the corona discharge of the ionizer. The concentration of particles after collector remarkably varied in the region between the high voltage and grounded electrodes. The collection efficiency right behind the high voltage electrode is much greater than that behind the grounded one. The total collection efficiency, calculated by integrating the particle concentration in whole measuring region, is greater when the high voltage electrode of the collector is located behind the discharge electrode of ionizer. Thus, the relative position of the ionizer and collector electrodes affects the precipitation characteristics.

The purposes of this study was to analyze qualitatively changes in students' experience and perceptions in relation to studying science using portfolios and any resultant effects on the portfolio itself. Five fourth-grade elementary students from one small city participated in this study. Data was collected through interviews as well as through student portfolios containing the science content matter of two units over two weeks. Observational diaries recorded by a teacher were also used to test the reliability of data collection. All interviews with students were transcribed to develop a suitable network to categorize students' responses. Students' portfolios were analyzed in order to reveal their essential characteristics in combination with their teacher's observational diaries. The results were as follows. First, student perceptions of their portfolios were categorized into three different levels; superficial, extended, and moderate perceptions. The changes in perception could also be divided into three levels; consistent-superficial, unstable, and a progressive-extended pattern. Second, the experience of students with their portfolio were investigated in terms of the following; successfully completing the elements of the portfolio, development of evidence, interaction with peers, teachers, and parents, and the standards of evaluation used for the portfolios. Third, the perceptions and experience of working on the portfolio by students had a number of direct effects on the way in which students actually created and developed their portfolios. Finally, students with positive attitudes towards their portfolios actively participated in the portfolio experience and finally understood what it meant completely. However, students with negative attitudes regarding portfolio based work, did not leave the experience with any heightened awareness of the utility or indeed, purpose of portfolio based work.

Objective: This study investigated the moderating effect of emotional dysregulation on the relationship between teacher efficacy and job stress among teachers in the Early Childhood Education and Care (ECEC). Methods: The participants included 586 ECEC teachers from 99 centers in Seoul, Gyeonggi-do, Daejeon, Chungcheong-do, Jeolla-do, and Gyeongsang-do. The data were analyzed through frequencies, percentages, and Pearson's correlations using SPSS 21.0 (IBM Co., Armonk, NY). To analyze the moderating effect, Ping's (1996) two-step approach was used via AMOS 20.0 (IBM Co., Armonk, NY). Results: The main findings are as follows. First, the mean scores of ECEC teacher efficacy and job stress showed above the average, and the mean score of emotional dysregulation was the nearly average. Second, fit statistics indicated that the proposed model, as revised, provided an acceptable fit to the sample data. This proposed model showed that the emotional dysregulation of teachers in ECEC had a moderating effect on the relationship between teacher efficacy and job stress. Conclusion: These findings imply that the ECEC teachers showed the higher level of self-trust and self-confidence than average regarding their own work, and suffered from the work overload. Also, the positive and supportive working environment would help the ECEC teachers to reduce their emotional dysregulation. In addition, there was a moderating effect of the ECEC teachers' emotional dysregulation on the relationship between teacher efficacy and job stress. These findings imply that the workshop or counselling programs need to be provided to teachers in order to help control their emotion dysregulation and reduce their job stress.
