Parents in South Korea are known for their high level of educational zeal for their children. As a result, their children usually take extra classes in institutions as well as participate in other extracurricular activities such as sports and music. The purpose of this study was to examine the lifestyle and dietary behaviors of Korean elementary students involved in such activities. The total number of subjects was 550 fourth to sixth graders in elementary schools in Sejong, Korea. Of the total subjects, 88.0% were involved in extracurricular classes or other activities for an average of 7.34 hours/week. The subjects were assigned to one of four groups based on the degree of extracurricular activities: No extra-class (n=66), Low extra-class (1${\leq}$taking time<5 hours/week, n=118), Medium extra-class (5${\leq}$taking time<10 hours/week, n=184), and High extra-class (taking time${\geq}$10 hours/week, n=182). More subjects in the High extra-class group went to bed late (P<0.01), were under stress (P<0.01), and skipped breakfast, compared with those in the other groups. The ratio of students who answered 'I go to an institute without a meal' (P<0.01), 'I prepare a meal for myself' (P=0.053), or 'I eat out before going to an institute' (P<0.01) was higher in the High extra-class group than in the Low extra-class group. The frequency of eating fast food was higher in the High extra-class group, compared with the other groups. These results indicate that a high amount of extracurricular studies may have a negative effect on the children's lifestyles and dietary behaviors. Therefore, this study alerts parents to the potential harm of excessive extracurricular activities to their children's health.

This research investigated the influence of subjective well-being on attitude towards minority group members. In a cross-sectional data, the higher subjective well-being predicted more positive cognitive beliefs, affective feelings, and behavioral intentions towards foreign laborers and children of international couples. The causal link from subjective well-being to greater tolerance for cultural diversity was found again in a large longitudinal sample. The rate of life satisfaction increase from Time 1 to Time 2 significantly predicted multicultural receptiveness at Time 2. Overall, the findings suggest that subjective well-being may contribute to the formation of favorable attitude towards minority group members.

In this paper, data mining regression analysis and decision tree analysis techniques were used to analyze factors affecting the life satisfaction of middle school students. For this purpose, we analyzed Korean Children and Youth Panel Survey(KCYPS) data. As results, the common influencing factors to the life satisfaction were derived from regression analysis. Those factors are self-esteem, depression, total grade satisfaction, regional community awareness, career identity, annual delinquency damage experience, siblings' factors, trust, behavioral control, and concentration. Based on the result described by decision tree analysis, the factors that indicate a significant impact on the life satisfaction of middle school students were self-esteem, depression, career identity and attention factor.

Objective: This study examined the relationships among attention deficits/hyper activities problems(ADHD problems), executive function difficulties, and social capital inside the family, especially with the mediating effect of social capital inside the family, in children from dual-income households. Methods: The participants were 401 children from dual-income households from the eighth wave of the Panel Study on Korean Children. They belonged into lower and higher ADHD problems groups that showed below 25% or more than 75% of ADHD screening items' total score. The data were analyzed by t-test, correlation analysis and mediating effect test by PROCESS macro 3.5.3.. Results: Children's executive function difficulties and social capital inside the family were significantly different between the two lower and higher ADHD problems groups. A mediating effect was found based on the negative relationships between the social capital inside the family including mother's warm childrearing behavior and positive coparenting, and children's executive function difficulties. Children's ADHD problems had a negative influence on each of the two social capital variables and each of the two variables had a negative influence on the executive function difficulties. Conclusion/Implications: These results emphasize the meaningful role of social capital inside the family in the development of first graders with ADHD problems from dual-income households.

Using a person-centered approach, the current study investigated latent profiles for the emotional and behavioral problems of students in sixth-grade in elementary school and second grade of middle school. The aim was to explore latent transition patterns and verify the factors affecting the transitions. The participants were 1,937 adolescents who responded to the 3^rd year (6^th grade of elementary school; Time 1), 4^th year (1^st grade of middle school), and 5^th year (2^nd grade of middle school; Time 2) of the Korean Children Youth Panel Study. Latent profile and latent transition analyses were performed. The results were as follows: first, the latent profile of emotional and behavioral problems changed from Time 1 to Time 2. The latent groups at Time 1 were classified into low, moderate, high, and externalizing-dominant, whereas at Time 2, five groups were identified: low, moderate, high, externalizing-dominant, and withdrawal-dominant. Second, transition analyses revealed that although 22.3-57.0% of latent groups remained unchanged, there were significant changes over time between groups, as a new group ('withdrawal-dominant') emerged in Time 2. Third, different factors influenced the latent profile transition of emotional and behavioral problems depending on the transition pattern. Higher levels of self-esteem, better relationships with peers and teachers, and lower levels of parental inconsistency meant emotional and behavioral problems had not worsened at Time 2. The results suggest that early interventions are needed during the transition from childhood to early adolescence.

Family is a primary unit of the major socialization processing for children. Parents among the family members are one of the most important figures from whom the child and adolescent acquire a wide variety of behavior patterns, attitudes, values and norms. An organization of family members product family structural functioning. Abnormal family structure is one of the most important reference models in the learning of antisocial patterns of behavior. Therefore incest and child sexual abuse including spouse abuse, elderly abuse, and neglect occurs in the abnormal family structural setting. In particular, incest, a specific form of sexual abuse, was once thought to be a phenomenon of great rarity, but our clinical experiences, especially over the past decade, have made us aware that incest and child sexual abuse is not rare case and on the increasing trend. Therefore, the aim of this study was to determine the family problem and dynamics of incest family, and character pattern of post-incest adolescent victim in Korea. A total of 1,838 adolescents from middle and high school(1,237) and juvenile correctional institute(601) were studied, sampled from Korean student population and adolescent delinquent population confined in juvenile correctional institutes, using proportional stratified random sampling method. The subjects' ages ranged from 12 to 21 years. Data were collected through questionnaire survey. Data analysis was done by IBM PC of Behavior Science Center at the Korea university, using SAS program. Statistical methods employed were Chi-square, principal component analysis and t-test etc. The results of this study were as follows ; 1) Of 1,071 subjects, 40(3.7%) reported incest experiences(sibling incest : 1.6% ; another type of incest : 2.1%) in their family setting. 2) The character pattern of post-incest adolescent victim was more socially maladjusted, immature, impulsive, rigid, anxious and dependent than non-incest adolescent. Also they showed some problem in academic performance and their assertiveness. 3) The other family members of incest family revealed more psychological and behavioral problem such as depression, alcoholism, psychotic disorder and criminal act than the non-incest family, even though there is no evidence of the context between them. 4) The family dynamics of incest family tended to be dysfunctional trend, as compared with non-incest family. It showed that the psychological instability of family member, parental rejection toward their children, coldness and indifference among family member and marital discordance between the parents had significant correlation with incest.

This study explored the longitudinal developmental paths of preschooler's external problem behaviors from infancy. Subjects consisted of 205 preschoolers (106 boys, 99 girls aged 4) and their mothers recruited for the 2009 in-depth Panel Study on Korean Children. Data were analyzed by descriptive statistics, correlations, and structural equation modeling using SPSS 18.0 (SPSS Co., Chicago, IL, USA), Amos 18.0 (SPSS Co., Chicago, IL, USA). The results were as follows: Maternal depression at preschooler's age 0 had a direct effect on maternal social parenting style at preschooler's age 0. Maternal social parenting style at preschooler's age 0 had a direct effect on preschooler's effortful control at age 1. Preschooler's effortful control at age 1 had a direct effect on preschooler's external problem behaviors at age 4. Marital conflict at preschooler's age 0 did not have a direct effect on preschooler's effortful control at age 1. The direct effects of maternal depression at preschooler's age 0 on preschooler's effortful control at age 1, and on preschooler's external problem behaviors at age 4 were not significant. In addition, direct effect of maternal social parenting style at preschooler's age 0 on preschooler's external problem behaviors at age 4 was not significant. This study showed that maternal psychological characteristics, marital conflict, maternal social parenting style and preschooler's effortful control in infancy should be considered simultaneously to explain the effect on preschooler's external problem behaviors.

Object : This study aimed to identify the factor structure of Korean-Child Behavior Checklist 1.5-5 Dysregulation Profile (K-CBCL 1.5-5 DP) in infants and toddlers with mental disorders and verify differences in K-CBCL 1.5-5 DP among the diagnosis groups. Methods : The participants were 265 mothers of infants and toddlers with mental disorders who completed K-CBCL 1.5-5 DP. The data was analyzed using AMOS 25.0 and SPSS 25.0. Results : First, the bifactor model was the most suitable for the factor structure of the K-CBCL 1.5-5 DP. Second, there were significant differences among the diagnosis groups, such as communication disorders, pervasive developmental disorders, emotional disorders, and developmental delays. It was confirmed that the pervasive developmental disorder and emotional disorder groups showed significantly higher dysregulation compared with the communication disorder group. Conclusion : This study confirmed that infants and toddlers had dysregulation problems. Using the bifactor model, the multidimensional nature of the K-CBCL 1.5-5 DP was assessed. It was also meaningful that dysregulation could contribute to onset and deepening of symptoms of pervasive developmental disorders and emotional disorders in infancy.

It is known that as many as 1 in 91 children are diagnosed with an autistic spectrum disorder, and the incidence rate of the autistic spectrum disorder is much higher than that of cancer in Korea. It is necessary to develop a novel technology to sense their emotional status and give proper psychological diagnosis and therapy, since the children with autistic spectrum disorder usually do not express their own emotional status. This article presents the state-of-the-arts on the affective computing technologies that include recognition of emotional status through bio-sensing and virtual affective agent modeling, and then proposes a novel system architecture for diagnosis and therapy of autistic spectrum disorder. The diagnosis and therapy system of autistic spectrum disorder is composed of bio-sensing module, virtual environment module with affective agents, and haptic interface module. The architecture proposed in this paper will enhance the objectivity to diagnose autism spectrum disorders, and enable continuous treatment in daily life.
