The purpose of this study was to investigate sex differences in outcome expectation for aggression, and to study the effects of sex of target child and degree of provocation on the consequences that a child anticipates for aggression. The subjects were 30 boys and 30 girls in the 6th grade of a public elementary school located in Seoul. The children were tested individually by an adult who read the items to the child. Perry, Perry, and Weiss's Outcome Expectation Questionnaire, The modified consisting of 48 items was used in this study. The data were analysed by analyses of variance with repeated measures and t-test. Boys expected less guilt and negative self-reactions for aggression than girls. When provoked, children expected more tangible reward and less parental disapproval than when not provoked. When aggressing toward boys, children expected more tangible rewards, less parental disapproval, and less peer disapproval than when aggressing toward girls.

This study examined the effects of maternal parenting behaviors, children's social information processing, daily hassles, and emotional regulation on school-age children's aggressive behaviors using Structural Equation Modeling(SEM) analysis. Subjects were 589 children in 4, 5, 6th grade and their mothers from three elementary schools in Seoul, Korea. Data were analyzed with descriptive statistics and SEM analysis by SPSS 12.0 and AMOS 4.0. The SEM shows differences between overtly aggressive and relationally aggressive children. Maternal parenting behaviors affected their children's overt aggression through children's emotional regulation. Additionally, maternal parenting behaviors affected children's overt aggression through children's daily hassles and social information processing. Maternal parenting behaviors influenced children's relational aggression through children's daily hassles and children's social information processing.

The purpose of this study is to examine the effects of knowledge base and metamemory in children's conceptual implicit memory with category-exemplar-generation task. Subjects were total 180 children of each 60 from Grade2, Grade6 and High school students. They were examined implicit memory with category-exemplar-generation task, knowledge base test, and metamemory test. The data were analyzed using ANCOVA, and Scheffe post hoc test. The result was following: First, as the child grow old, implicit memory primed increased. Implicit memory amount was significantly different between Grade2 and High school students, Grade6 and High school students. Second, as the child grow high knowledge base, implicit memory primed increased. There was a significantly different found between age and knowledge base. Third, as the child grow high metamemory, implicit memory primed increased. These results were interpreted as that the state of the age, knowledge base and metamemory should be an important factorin implicit memory. And current findings suggest that implicit memory can show development if a children's knowledge base and metamemory in developing with age.

This study sought to examine the impact of reading ability and vocabulary at age 5, as well as analyzing the impact which children's gender, parental education level and family income level has on reading comprehension ability and vocabulary at the first grade level in primary school. The study also sought to compare the characteristics of the results obtained in Korea and Japan on this particular research topic. For the Korean part of the study, 328 first grade Korean children, who had participated in the initial testing as five-year olds and agreed to participate in the longitudinal study were tested; whereas in Japan, 215 students were tested. The study results indicated that, in the case of Korea, reading comprehension ability in the first grade was affected by vocabulary and reading abilities at age 5, gender, as well as the mother's education level, in that order. In Japan, it was affected in the order of vocabulary, gender, and father's education level. In terms of first grade vocabulary, in the case of Korea, it was affected in the order of vocabulary and reading ability at age 5 and father's education level; whereas in Japan, it was affected in the order of vocabulary, gender, and reading ability. In both Korea and Japan, at age 5, vocabulary was shown to have a more significant impact than reading ability on both of language ability and vocabulary in the subsequent primary school period. As such, it can be seen that more interest should be shown not only in the ability to read at age 5 but also in expanding the vocabulary of children at this age through appropriate interaction and support.

The purpose of this study was to investigate the relationships between children's self-concepts and (1) types of functional family systems. (2) family cohesion and adaptability levels, and (3) the satisfaction of children with their current family systems. The subjects of this study were 347 middle S. E. S. children (168 boys, 179 girls) in grade 6. Analysis of functional family systems was by The Family Adaptability and Cohesion Evaluation Scales III(1985) of the Circuplex Model (Olson et al., 1979). The Self-concept Inventory (Lim Jae Leun, 1987) was used to assess children's self-concepts. The data were analyzed with one-way ANOVA, $Scheff{\acute{e}}$ and Pearson correlation. It was found that there were no differences in children's self-concepts by types of functional systems. There were differences in children's self-concepts by family cohesion and adaptability levels. That is, the higher the level of cohesion and adaptability the more positive the child's self-concept. The more the child was satisfied with his/her current family system, the more positive the child's self-concept. Children whose family systems were at a high level of family cohesion and adaptability were more satisfied with their current family systems.

The phonemic awareness program included construction of 45 activities emphasizing various sounds in speech and letter names using a storybook. The subjects were thirty 1st and 2nd grade low-income(15 experimental and 15 control group) children attending an after-school program in Seoul. Pre- and post-tests assessed children's reading, self-concept, and learning motivation. The experimental group children had rich opportunity to deal with and discuss sounds, syllables, phonemes, and the Korean alphabet names during storybook reading, games, and play over a 12 week period, while the control group children were provided with worksheets, subject tutoring, and homework guidance. Results showed that the phonemic activities were an effective and useful way to enhance children's reading ability, self-concept, and learning motivation.

This survey of children's perceptions and experiences of death was conducted with 118 6th-grade elementary school children in Seoul. Data consisted of responses to questionnaires in three categories : (1) perceptions of death, (2) views of afterlife, and (3) death-related experiences (life, education, and media). Results showed that children had negative emotions (61.8%) such as fear and anxiety about death. Children's attitudes about suicide were sympathetic (34.5%) as well as critical (53.7%). There was no relation between religion and view of afterlife. Finally, children experienced death more through mass media (TV, internet, etc.) than through life experience or death education. This study suggests the necessity for death education and warns of negative effects of media and games.

Boys had more problem behaviors; girls showed better competencies. Bullying was positively related to acting out, and negatively related to frustration tolerance and task orientation. Victimization was positively related to shy-anxiousness and learning problems, and negatively related to frustration tolerance, assertive social skills and task orientation.

The present study was designed to assess the effect of relationship on children's distributive justice reasoning. 259 kindergarten, second-grade, and fifth-grade children were asked to allocate 9,000 Won to 3 characters under three different relationship conditions (strangers, peers, and siblings), provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children were sensitive to relationship information such as allocation of more money to productive rather than to needy or older strangers, more to needy friends than to productive or older friends, and more to older than to a productive sibling. However, young children relied on only one principle, equality, across the relationship conditions. Kindergartners viewed allocations based on age entitlement as fairer than older children did, whereas both groups of older children rewarded individuals based on equality in stranger, equality and need in peer, and equality and equity in sibling relationships.
