This paper demonstrated how application of evolutionary knowledge to developmental perspectives enhances understanding of human ontogeny. Evolutionary Developmental Psychology (EDP) explains human behavior through evolutionary principles and focuses on ontogeny rather than phylogeny. In this paper, the authors review concepts of evolution, adaptations, and the processes of evolution from EDP perspectives. The definition and basic assumptions of EDP are introduced, followed by explanations of how evolution happens in ontogeny by looking at developmental systems approaches, concepts of ontogenetic and deferred adaptations, evolution of childhood, and brain plasticity. Possible pathways of evolution in ontogeny are also discussed. Finally, some research methodology for applying EDP to child development is suggested with specific hypotheses and studies.

This study intended to understand how the use of social welfare services and the satisfaction from the use affect poor children's psychosocial adjustment. Especially, it focused to find out whether the use of satisfied services has an independent effect on poor children's psychosocial adjustment when other relevant variables are controlled. Participants are 904 poor children from 16 nationwide cities/provinces who receive financial sponsorship from Korea Welfare Foundation in cooperation with the Ministry of Health and Welfare. Among them, 8.2% is from youth-headed homes, 22.7% is from grandparent-care homes, 8.2% is from relative foster homes, 1.8% is from non-relative foster homes and 59.1% is from other poor families. The results of this study are as follows: 1) According to MANOVA, poor children who received 2 or more satisfied social welfare services are significantly different from those who received 1 or no service in their combined psychosocial adjustment subcategories. Delinquency among the subcategories is the most influencing variable in combined differences. 2) Controlling sex, age, family structure and other variables that are considered to be related to delinquency in previous research, the use of satisfied services is still the significant variable in decreasing delinquency among poor children. 3) Interaction effect between the use of satisfied services and parental supervision was statistically significant. Under the low level of parental supervision, the use of satisfied services has a significant effect on the decrease of delinquency. However, under the high level of parental supervision, the use of satisfied services has little effects. From these results, we found out that the use of satisfied social welfare services is a very significant factor influencing to prevent or decrease delinquency among poor children. Also we found out that it is critically important for poor children who receive the low level of parental supervision to have good-quality social welfare services in order to prevent delinquency.

The purpose of this study was to investigate the child counselling process of a 6-year old girl. The child has showed inattention and impulsity. Her mother had difficulty on caring a child. The researcher conducted 63 session child counseling through play therapy once per week after tested clinical psychological full battery. During the counseling process, a child showed desire of affection and aggressive and impulsive behavior through the child's leading play. As a result the child's inattention and impulsivity decreased, and child-mother relationship improved. The child could express her feelings to their parents in concrete terms. Finally, the child successfully adapted new school life. The mother reported that raising children was much easier than before, and she decided to have a follow-up counseling once a month. This study is meaningful in that it is a case study conducted during 1 year and 8months since she was 6-year old. The young child becomes primary school girl. In this study, it was confirmed that children had an adaptive school life during the first and second grades.

The objective of this study was to examine the mediating effects of school adjustment on the relationship between social capital and self-reliance of adolescents in out-of-home care(institutional care, foster care, and group homes). For this study, a total of 358 middle and high school students(13 to 19 years) were recruited among adolescents in care nationwide. Collected data were analyzed by using the structural equation modeling analysis. A bootstrapping method was utilized to examine the mediating effects. The results showed that social capital of the adolescents in out-of-home care was not directly related to self-reliance. However, complete mediation was found through school adjustment in the relationship between social capital and self-reliance. This indicates that social capital of the adolescents in care was significantly related to self-reliance only through school adjustment. Based on the results, policy and practice implications for increasing the levels of social capital, school adjustment, and self-reliance of adolescents in care were discussed.

The purpose of this study is to find methods to prevent and improve smart device over-dependence problems by analyzing differences in school life adaptation and academic performance according to children's dependence on smart devices. For this, the data of fifth grade elementary school students in the 12th year were extracted and utilized from Panel Survey of Korean Children. The data were analyzed using non-hierarchical cluster(K-means) analysis, T-test, one-way ANOVA, and Scheffé tests. The results of this study are as follows. First, It has been shown that dependence on smart devices, school adaptation and academic performance have a negative correlation. Second, students in potential and high-risk groups who are highly dependent on smart devices have significantly lower school adaptation compared to those in the safety group. Third, high-risk students showed significantly lower academic performance compared to those in the potential risk group and general group. Based on these findings, it was suggested that for elementary school students who rely on smart devices, various learning support and national efforts such as counseling for school life adaptation are needed.

The purpose of the study was to estimate the trajectories of elementary school adjustment in grades 1 through 4. For the purpose, the Korean Children's Panel data were analyzed using potential growth model and the growth mixture model. As the result, the linear model was selected as the optimal model. The four potential groups were derived as trajectories: high-level maintenance, low-level maintenance, low-level increase, and high-level decrease. In terms of group distribution, the most children were in high-level maintenance group and then low-level maintenance, low-level increase, and high-level decrease in order. Based on the findings that trajectories of elementary school adjustment changes as children growth, we suggest that schools and families need to carefully investigate and support their school adjustment in individual levels.

This study investigated whether children's self-control and sense of humor could moderate negative effects of daily hassles on their school adjustment. Subjects of this study were 880 6th graders (468 boys, 412 girls) in the Seoul metropolitan area. Children reported their daily hassles, school adjustment, self-control, and sense of humor on questionnaires. The collected data were analyzed using descriptive statistics, Pearson's correlation analysis, and moderated regression analysis. Results showed that children who experienced less daily hassles, had higher self-control, and higher sense of humor were well-adjusted in their schools. Children's self-control and sense of humor moderated negative effects of daily hassles on school adjustment of children, although the moderate effect was weak.

The aim of this paper is to examine the effects of children's ego-resilience and social support on exam anxiety and school adjustment. The subjects of this study were 534, $5^{th}$ and $6^{th}$ grade students (275 boys and 259 girls) from the Pusan area. The results of this study revealed that the levels of Ego-resilience and social support correlated negatively with exam anxiety, and positively with school adjustment. Therefore the more ego-resilience and social support children felt that they had, the lower the levels of exam anxiety they experience, and the higher their levels of school adjustment. The influence of ego-resilience on exam anxiety was higher than that of social support and the influence of ego-resilience on school adjustment was similar to that of social support. The implications of the present study were also discussed.

This study examined the moderated mediating effect of stress by self-concept on the influence of ego-resiliency on school adjustment in children. The participants consisted of 278 4th-graders, who completed self-report questionnaires designed to assess ego-resiliency, school adjustment, self-concept, and stress. The results indicated the following: First, stress mediated the effect of ego-resiliency on school adjustment. Second, self-concept moderated the effect of stress on school adjustment. Third, the mediating effect of stress on the influence of ego-resiliency on school adjustment was moderated by self-concept. The mediating effect of stress was statistically significant when self-concept was positive, but was not statistically significant when self-concept was negative. Methods to improve children's school adjustment are also included, based on the results of this research.
