  • In this paper, we propose the moderating effects of self-efficacy and social support on the relationship between physical therapists' job stress and psychological burnout. Based on the previous studies, this study set up three types of variables: 1) independent variable, 2) moderating variable, 3) dependent variable. Job stress was identified as an independent variable, self-efficacy and social support was identified as a moderating variable and psychological burnout was identified as a dependent variable. To empirically conduct this study, a total of 200 questionnaires were distributed to physical therapists. Consequently, a total of 155 survey responses were collected. The survey results are as follows. First, the result showed a high-level of correlation among job stress, psychological burnout, self-efficacy, and social support. Second, self-efficacy was found to have a moderating effect on the relationship between the physical therapists' job stress and psychological burnout. Third, social support was found to have a moderating effect on the relationship between the art therapists' job stress and psychological burnout.

  • In the variable speed Wind Turbine based on ElectroMagnetic Coupler (WT-EMC), a synchronous generator is coupled directly to the grid. Therefore, like conventional power plants, WT-EMC is able to inherently support grid frequency. However, due to the reduced inertia of the synchronous generator, WT-EMC is expected to be controlled to increase its output power in response to a grid frequency drop to support grid frequency. Similar to the grid frequency support control of Type 3 or Type 4 wind turbine, inertial control and droop control can be used to calculate the WT-EMC additional output power reference according to the synchronous generator speed. In this paper, an experimental platform is built to study the grid frequency support from WT-EMC with inertial control and droop control. Two synchronous generators, driven by two induction motors controlled by two converters, are used to emulate the synchronous generators in conventional power plants and in WT-EMCs respectively. The effectiveness of the grid frequency support from WT-EMC with inertial control and droop control responding to a grid frequency drop is validated by experimental results. The selection of the grid frequency support controller and its gain for WT-EMC is analyzed briefly.

  • In this paper, we propose the moderating effects and mediation effects of social support on the relationship between art therapists' job stress and psychological burnout. Based on the previous studies, this study set up four types of variables: 1) independent variable, 2) moderating variable, 3) mediation variable, and 4) dependent variable. Job stress was identified as an independent variable, social support was identified as both a moderating variable and mediation variable, and psychological burnout was identified as a dependent variable. To empirically conduct this study, a total of 200 questionnaires were distributed to art therapists. Consequently, a total of 150 survey responses were collected. The survey results are as follows. First, there were not differences in job stress, psychological burnout, and social support due to personal environmental factors. This included career, employment type and working hours. Second, the result showed a high-level of correlation among job stress, psychological burnout, and social support. Third, social support was found to have a moderating effect on the relationship between the art therapists' job stress and psychological burnout. Forth, social support was found to have a moderating effect on the relationship between the art therapists' job stress and psychological burnout.

  • This study investigate the influence of resilience on organizational commitment using social support as a mediating variable for kindergarten and childcare teathers. The subjects were 630 kindergarten and childcare teathers. The collected data were analyzed by Pearson's correlation as well as single and multiple regressions that used SPSS Win 19.0. The results were as follows: (1) The resilience was significantly associated with organizational commitment of kindergarten and childcare teachers. (2) The resilience was significantly associated with social support of kindergarten and childcare teachers. (3) The resilience was not significantly associated with organizational commitment of kindergarten and childcare teachers, controlled by social support. The results showed the social support was more important variable affecting organizational commitment of kindergarten and childcare teachers than the resilience. As a result, teachers have to be strengthened for support of social emotion that helps to control of their emotional condition and social evaluation that estimates their role positive under administration system.

  • This study examined different individual, family factors and classroom environment that affect children's perceived competency. For an analysis, achievement motivation, intrinsic locus of control and anxiety were included in individual variables. For family factors, parental support and marital conflict were examined. For classroom psycho-social environment, teacher support, peer relations, classroom involvement and teacher control were used. The sample consisted of 565 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, Factor analysis, frequency, percentage, t-test, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis. First, boy's perceived academic competency was higher than girl's. And no sex difference was in children's social and athletic competency. Second, boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support, teacher support, peer relations and classroom involvement. And girl's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support and peer relations. But boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a negative correlation with anxiety and parental marital conflict. Third, the most important variable predicting boy's and girl's perceived academic competency was achievement motivation. The most important variable predicting boy's and girl's perceived social competency was peer relations. And the most important variable predicting boy's perceived athletic competency was peer relations. On the other hand, the most important variable predicting girl's perceived athletic competency was father's support.

  • The Purpose of this study was to investigate the ecological variables on adolescent's sociometric popularity. Independent variables were organism(sex, age, aggression, self-esteem, impulsiveness, prosocial behavior, dominance), microsystem(parenting style, family support, friends relationship, teacher support), mesosystem(family-peer relationship, family-school relationship), and exosystem(positive community environment, social support of extended family, school's policy). The subjects were 835 - 1st and 2nd graders of two middle and two high schools in Daegu. Adolescent's sociometric popularity and ecological variables were measured with questionnaire. Adolescent's sociometric popularity was measured with sociometric popularity questionnaire. Organism variables were measured with sex, age, aggression, self-esteem, impulsiveness, prosocial behavior and dominance questionnaire. Microsystem variables were measured with parenting style, family support, friends relationship and teacher support questionnaire. Mesosystem variables were measured with family-peer relationship and family-school relationship questionnaire. Exosystem variables were measured with positive community environment, social support of extended family and school's policy questionnaire. The data analyzed by frequency, percentage, mean, cronbach's $\alpha$, and multiple regression. The major findings were as follows: First, adolescent's sociometric popularity was affected by age, overt aggression, academic self-esteem, social self-esteem, and impulsiveness of organism variables. Second, adolescent's sociometric popularity was affected by mother's affectional parenting, mother's control parenting, and attachment to friends of microsystem variables. Third, adolescent's sociometric popularity was affected by family - peer relationship and family - school relationship of mesosystem variables. Fourth, adolescent's sociometric popularity was affected by appraisal support of extended family, after-school activity, and circle activity of exosystem variables.

  • The purpose of this study is to identify the mediating effect of social support in the relationship between job stress and stress coping strategies among male workers on a three-shift system. The subjects of the study were 146 male workers working in manufacturing companies with more than 500 employees located in C City, Chungbuk Province, who understood the purpose of the study and agreed to participate. The collected data were analyzed using frequency and percentage, descriptive statistics, Pearson Correlation Coefficient, and multiple regression analysis. Job stress had a significant effect on the mediating variable, social support (β=.34, p<.001), and job stress had a significant effect on the dependent variable, stress coping strategies (β=.41, p<.001). When examining the effect of social support on stress coping strategies (β=.35, p<.001), social support was found to be a significant predictor of stress coping strategies. Therefore, social support plays a mediating role in the relationship between job stress and stress coping strategies among male workers on a three-shift system, and job stress and social support explained 27.4% of the variance in stress coping strategies. Thus, it is necessary to establish a psychological support system that can reduce job stress through active stress coping measures that consider the social support of male workers on a three-shift system.
