  • The purpose of this study was to analyze the causal relationship among students' science-related career choice and its factors. The causal relationship was analyzed using structural equation modeling. According to the most fitting model, science career aspiration had a direct and total effect of 0.95 (standardized coefficient) on the science career choice, and personal factor had an indirect and total effect of 0.75 on the science career choice, educational factor, 0.46, and social factor, 0.11. Personal factor had a direct and total effect of 0.79 on the science career aspiration, educational factor with total effect of 0.48 (direct effect -0.21, indirect effect 0.69), and social factor with direct and total effect of 0.12. On the other hand, educational factor had a direct and total effect of 0.72 on the social factor, and a direct and total effect of 0.77 on the personal factor. The difference in the causal effect among grades and between gender was analyzed. The difference was only in the magnitude of influence among grades, showing the same tendency with the total number of students, but the difference between gender was contrastive. For the boys, social factor had the biggest effect on the science career choice, next was personal factor, and the educational factor had the smallest effect. The girls' science career choice influenced mostly from personal factor, and the other two factors' effects were not high. The social effect was negative for the girls' science career choice. The implications of proper science career education were discussed from these results, considering the causal relationship among factors of science career choice and its factors.

  • This study covers an investigation using meta-analysis of the factors related to the effects of singing activities for children, focusing on the dissertations conducted for master and doctor degrees and the studies published in academic journals over the past 16 years. Ameta-regression analysis was conducted to examine the changes of the factors in each published year. The analysis results were as follows: Both the entire effect size and the groups of singing activity related factors were revealed to have significant effect sizes. While the group of social factors and the group of cultural & artistic factors showed large effect sizes, the group of psychological & emotional factors appeared to have an intermediate effect size. The sub-factors of the group of social factors were shown to have significantly larger effect sizes than the others, except for the factor of capability of recognizing others. Among the sub-factors, naturally friendly behavior showed relatively larger effect size than the others. In the sub-factors of the group of psychological & emotional factors, self-expression capability and self-control capability showed large effect sizes and stress suppression and emotional intelligence showed intermediate effect sizes. Among the sub-factors of the group of cultural & artistic factors, except for creative capability which showed an intermediate effect size, all of the sub-factors showed large effect sizes. According to the results of the analysis of the trend of the effect size changes in each published year, the trends of the entire effect size and the effect size of each factor, such as the groups of social factors, psychological & emotional factors and cultural & artistic factors, showed that the activity effects increase as the publication year comes closer to the most recent year.

  • In this paper, we decomposed Greenhouse-Gas emissions of Korea's manufacturing industry using LMDI (Log Mean Divisia Index) method. Changes in $CO_2$ emissions from 1991 to 2007 studied in 5 different factors, industrial production (production effect), industry production mix (structure effect), sectoral energy intensity (intensity effect), sectoral energy mix (energy-mix effect), and $CO_2$ emission factors (emission-factor effect). By results, the structure effect and intensity effect has a role of reducing GHG emissions and The role of structure effect was bigger than intensity effect. The energy mix effect increased GHG emissions and emission-factor effect decreased GHG emissions. By time series analysis, IMF regime affected the GHG emission pattern. the structure effect and intensity effect in that regime was getting worse. After 2000, in the high oil price period, the structure effect and intensity effect is getting better.

  • The purpose of this study is to examine the moderating effects of protective factors on the relations between deviant peer's influences and delinquent behaviors in adolescence. To investigate the moderating effects, simple slope and region of significance test based on multiple linear regression(MLR) model were used. This study used data from wave 1-2(2003-2004) of the Korea Youth Panel Survey(KYPS). Results showed that for female adolescents, self-esteem, parent monitoring, and attachment to parent moderated the link between best friend's deviancy and delinquent behaviors. For male adolescents, however, best friend's deviancy and protective factors didn't show any significant moderating effects. These results help clarify the conditions under which exposure to deviant best friends can influence delinquent behaviors in adolescence. Practice and policy implications as well as further research topic were discussed to aid the search for highly effective preventive and treatment interventions.

  • This study examines determining factors of effectiveness and satisfaction of Veteran Medical Service Delivery System. Especially, the association between the relevant variables of the effectiveness of the Veteran Medical Service Delivery System and the variables of the satisfaction from the perspective of beneficiaries was studied. Multi-level analysis was utilized to separate results of the evaluation of effectiveness in organizational-level and the evaluation of satisfaction in individual-level. This study tests key posited hypothesis by using survey data collected from 5 medical center of country(Seoul, Busan, Daejeon, Daegu, Gwangju). In terms of the result of the hypothesis testing on the effectiveness variable, integrity(${\beta}=.156$), accountability(${\beta}=.376$, financial sufficiency(${\beta}=.109$), and adequacy (${\beta}=.367$) are the determinants among various factors in evaluating veteran medical service delivery system, statistically reflecting the perception of directors of the veteran medical service delivery facilities on effectiveness. In other word, professionalism variable(${\beta}=0.99$) and effectiveness variable(${\beta}=-1.09$) are statistically reflecting the perception of directors of the beneficiaries satisfaction with employee. The findings suggests that the theoretical and practical implications will improve Effectiveness and Satisfaction of Veteran Medical Service Delivery System.

  • This study considers both causal and control factors for explaining both contact and distribution of sexually explicit material and tests their interaction effects for examining buffering effects of control factors in causal process. This study examines the effect of low self-control, differential association with peers and patriarchy family environmental factor as causal factors. It also considers three control factors such as morality. legal punishment, and lack of opportunity and test interaction effect between causal and control factors in both contact and distribution cases. Using data from college students in Seoul, results show that the effects of all causal factors are significant in both contact and distribution of sexually explicit material and the effect of differential association is the most significant. However, their interaction effects between causal and control factors are different across contact and distribution cases. In the contact case, all interaction effects are not significant. It means that causal factors have independent effects and control factors have no buffering effects. However, in the distribution case, the interaction effects between low self-control and morality, between differential association and morality, between patriarchy family and punishment, and between patriarchy family and lack of opportunity are significant. Empirical implications are discussed.
