Here we analyze a case of redesigned course named "Prospect of Nuclear Engineering" as an example of student-entered education which came to the fore of university education innovation. This course was reformed from lecture-based to student-centered class by changing the context as follows: Stimulating students by addressing various problems or episodes behind scientific and mathematical concepts in the history; Offering experimental project to perceive the importance of differential equations; Exploring the research status and issues of nuclear engineering and the ways of attacking them by discipline; Discussing the public acceptance of nuclear power plants. Small group activities using 'small group discussion' and 'peer-learning' have been applied in this course to enhance students' critical and creative ability. In the survey, students rated highly in the fact that they could actively interact with the peers and that they could think for themselves through 'small group discussion' and 'peer-learning' which is not just the way of conveying knowledge.

The purpose of this study was to find out the effects of mother's parenting attitudes on children's clothing orientation and clothing purchase behaviors. The questionnaires for this study were distributed to 166 fifth and sixth graders of elementary schools and 166 their mothers in Seoul. The data were analyzed through chi-square test, factor analysis, cluster analysis, MANOVA, ANOVA, and LSD test. Responses were classified as 4 groups (Acceptance-Autonomy, Acceptance-Control, Rejection-Autonomy, and Rejection- Control groups) based on mother's parenting attitude. The four groups showed significant differences both in clothing orientation and clothing purchase behaviors. Especially, the Rejection-Control group, which is easily influenced by peer students, placed much emphasis on fashionability of clothing and showed strong complaining behaviors toward unsatisfactory clothing selected by their mothers. Study results suggest the importance of mother's parenting attitude on analysis of target market for children's wear.

The purpose of this study was to examine the relationships between mothers' childhood experiences, satisfaction as a parent, spousal support in parenting and their children's perception of their child-rearing practices. The subjects were 321 fifth and sixth graders from two elementary schools in Seoul and their mothers. A revised version of the Mother-Father Peer Scale (MFPS; Epstein, 1983) was used to assess the mothers' child experiences. To measure parental satisfaction, the Parent Satisfaction Scale (PSS; Duke, Rose, & Halverson, 1997) was revised and used. A modified version of the Teamwork of Parenting Alliance Inventory (PAI; Abidin, 1988) was used to assess spousal support in parenting. A modified version of the Child-rearing Behaviors Questionaire (Park, 1995) was used to assess the mothers' child-rearing practices. The data were analyzed with descriptive statistics and a t-test. The results of this study were as follows. 1) Mothers who received a greater degree of independence encouragement and acceptance from their fathers tended to show more warmth/acceptance in their child-rearing practices than those who received a lesser degree of independence encouragement and acceptance from their fathers. Mothers who received a greater degree of independence encouragement from their own mothers tended to show more warmth/acceptance of their children but less permissiveness/nonintervention and rejection/restriction in their child-rearing practices when compared to those who received a lesser degree of independence encouragement from their own mothers. The mothers who received a greater degree of acceptance from their own mothers tended to show more warmth/acceptance of their children but less rejection/restriction in their child-rearing practices when compared to those who received a lesser degree of acceptance from their own mothers. 2) Mothers who had a greater degree of satisfaction as a parent tended to show more warmth/acceptance but less rejection/restriction in their child-rearing practices than those who had a lesser degree of satisfaction in parenting. 3) Mothers who received a greater degree of spousal support in parenting showed more warmth/acceptance in their child-rearing practices than those who received a lesser degree of spousal support.

The purpose of this study was to investigate the relationship between social support and perception of self-confidence in children by grade, sex, and other related variables. The subjects were 136 third-graders, 143 sixth-graders, and 161 eighth-graders in public schools located in Pusan. Instruments were Harter's Self-Perception Profile for Children and the Social Support Appraisal Scale (SSAS). The SSAS is a 31-item measure that taps children's perception of family, peer, and teacher support. The data were analyzed by frequency, percentile, ANOVA, Scheffe test, Pearson's correlation, and multiple regression. The main results showed that (1) children in 6th and 8th grades perceived higher peer support than children in 3rd grade, (2) except for social acceptance, the children in higher grades perceived themselves lower in self-competence than the children in lower grades, (3) there was a positive relationship between children's perception of self-competence and social support, and (4) the variables which influenced children's self-perception were, in descending order: socioeconomic status(${\beta}=.52$), age(${\beta}=.21$), social support(${\beta}=.10$). These three variables explained 38% of the children' self-perception.

In this article, we model the distributed relay assignment network as a many-to-one matching market with peer effects. We discuss two scenarios for throughput optimization of relay networks: the scenario of aggregate throughput optimization and the scenario of fairness performance optimization. For the first scenario, we propose a Mutual Benefit-based Deferred Acceptance (MBDA) algorithm to increase the aggregate network throughput. For the second scenario, instead of using the alternative matching scheme, a non-substitution matching algorithm (NSA) is designed to solve the fairness problem. The NSA improves the fairness performance. We prove that both two algorithms converge to a globally stable matching, and discuss the practical implementation. Simulation results show that the performance of MBDA algorithm outperforms existing schemes and is almost the same with the optimal solution in terms of aggregate throughput. Meanwhile, the proposed NSA improves fairness as the scale of the relay network expands.

The purpose of this study was to develop a social skills training program for rejected young children and to investigate the effects of the program. The developed program used several kinds of interaction methods such as instruction, modeling, rehearsal, feedback, and positive reinforcement. The contents of the program are consisted of role-play, art, language activities, and games. The experimental group with a sample of 9 four-year-old children was those children rejected by peers. There were the other 9 children assigned to the control group. The experimental group received the social skills training program for 50-60 minutes per day twice a week during 12 sessions, and the control group received no treatment. And 9 popular children also joined the program from ninth to eleventh sessions. As compared to the control group, children in the experimental group showed a significant increase in peer acceptance and social skills after they participated in the program.
