This study was designed to analyze the differences in science achievement and satisfaction between the environments of Face-To-Face (FTF) and Computer Mediated Communication (CMC), and between the interactions of Teacher-Students (TS) and Students-Students (SS). The activities for the interaction in the FTF and the CMC were carried out in the environments of traditional classrooms and the on-line network of communication computer, respectively. These experiments for four different groups (CMC-TS, CMC-SS, FTF-TS and FTF-SS) were performed with respect to 103 students of three 10th grade classes at a girls' high school in Chungju city. The questionnaires were composed of 5questions for achievement, and 13 questions on Likert scale for satisfaction. The data was analyzed using ANOVA, and through examination of each question about the satisfaction. The mean of the science achievement in learning activity was significantly higher in the CMC environment than the FTF. Also, the score in the TS interaction was meaningfully higher than the SS. Under the common environment of the CMC, science achievement and satisfaction in the TS interaction were significantly higher than in the SS. A similar result has been obtained in the satisfaction case even in the common environment of the FTF. The itemized analysis for the satisfaction shows a high score in the individual condition of CMC and TS, compared to that of FTF and SS, respectively. Thus, the school activity, formed in the TS interaction in the CMC environment is more effective at improving science achievement and satisfaction in the teaching and learning of science.

The purpose of this study is to confirm whether the parenting stress of mothers with preschool children mediated the parent-child interaction and parenting attitude on children's learning readiness. Data was used from the 5th (2012) to 7th (2014) Korean Children's Panel, and a total of 1,480 data sets were used for the analysis. The age of study participants was five years old. The Amos 23.0 program was used as an analytical tool, and the structural equation model analysis was applied to estimate the path coefficient corresponding to the research question. First, it was expected that mothers' parenting stress negatively affected the parent-child interaction, mother's parenting attitude, and children's readiness. Second, it was assumed that parent-child interaction and the mother's warm parenting attitude were positively significant to children's readiness. Third, the relationship between the parenting stress of mothers and children's learning readiness was partially mediated by a positive parenting attitude. The current study supplies valuable data to establish the educational support and efficiency strategy for domestic children. This study is meaningful in that it provides basic data in preparing a plan to more effectively provide educational support for domestic children.

The result of imaging segmentation becomes different with the parameters involved in the segmentation algorithms; therefore, the parameters for the optimal segmentation have been found through a try and error. In this paper, we propose the method to find the best values of parameters involved in the area-based active contour method using three-way ANOVA. The segmentation result applied by three-way ANOVA is compared with the optimal segmentation which is drawn by user. We use the global consistency rate for comparing two segmentations. Finally, we estimate the main effects and interactions between each parameter using three-way ANOVA, and then calculate the point and interval estimate to find the best values of three parameters. The proposed method will be a great help to find the optimal parameters before working the motion segmentation using piecewise constant model.

This purpose of this study is to examine the relationships of ethical leader and ethics management system with employees's organizational citizenship behavior and the mechanism underlying these relationships. A questionnaire survey was conducted involving 1,035 full-time employees from large and medium industries in Daegu and Gyeong-buk provinces. Regression analysis was used to test the hypotheses. The results showed that both of ethical leader and ethics management system were positively related with employees's organizational citizenship behavior. As expected, these relationships were mediated by organization-oriented ethical climate and social responsibility-oriented ethical climate respectively. The findings of this study are as followings: First, employees tend to show their pro-social behavior when they perceive their leaders act ethically and ethics management is well institutionalized. Second, building up the organization-oriented ethical climate and social responsibility-oriented ethical climate can be a powerful strategy to enhance employees's organizational citizenship behavior.
