This study the presents survey results of a families living with children with disabilities in northern Seoul (Nowon-gu and Dobong-gu) that provides various educational services. This study investigates the current usage and needs of community resources for children with disabilities by the families in the inclusive and segregated care as well as education centers to provide information for the effective implementation of the current system. A total of 109 surveys were distributed and 62 (57%) were returned. 44 families in the 14 inclusive care and education centers as well as 18 families in the 2 segregated care and education centers participated in this study. They were asked to report on access to community resources that include compulsory education, family support, medical treatment, counseling services, commuting support, ways to gain necessary information, current use, and further needs for community resources for their children. Research results indicated that families in two different types of child care centers needed differentiated community services. Parents who use a segregated child care center demanded physical accessibility and increased numbers of highly qualified teachers; however, parents who use the inclusive child care center require the unified information system for the community resources. Survey findings are discussed related to differences between the two types of child care centers. Implications for sharing comprehensive information through child care teachers and directors of child care centers and future research are also discussed.

This study examined the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness. In this Study, subjects were 274 children who were 4 through 5 years old. The participants included 274 preschoolers' parents and their teachers in D city. The parents completed questionnaires regarding parent's play participation with their children and children's self-regulation. The teachers completed questionnaires regarding preschoolers' happiness and playfulness. Data was analyzed using descriptive statistics, pearson correlation analysis and mediation analysis based on structural equation modeling with SPSS 25.0 and AMOS 23.0 program. Also, specific indirect effects were analyzed using AMOS user-defined estimand function. The primary results of this study were as follows. 1) The parent's play participation had an influence upon children's playfulness and self-regulation. 2) The children's playfulness had an influence upon children's self-regulation and happiness. 3) The children's self-regulation had an influence upon children's happiness. 4) Between the parent's play participation and children's happiness were mediated by the children's playfulness and self-regulation. This study revealed that parent's play participation, children's playfulness and self-regulation need to be considered simultaneously to explain the level of the children's happiness. The results highlight the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness.

This study investigates the effect of a leadership program to enhance leadership skills in children from low-income families. A total of 45 elementary school students participated in the 52-week leadership program. Five leadership scales, such as goal attainment, paradigm shifting skills, skills to lead others, human relationship skills, and sense of purpose, were measured through survey questionnaires before and after implementing the program. In addition, individual teacher interviews examined the influence of the program on students' leadership skills. This study found that participants showed significant improvement after implementing the program in the three domains of the leadership skills (goal attainment, paradigm shifting skills, and human relationship skills); however, the skills to lead others and sense of purpose did not significantly change. The leadership teachers also stated that the program influenced positively on students' leadership skills; in addition, students' behavioral changes were found by developing relationships with other children as well as contemplating and attempting to find a future dream and vision. The leadership program was effective to enhance leadership skills in children from low-income families. This study can provide the theoretical and practical foundations for the development and implementation of effective leadership programs that meet the needs of children from low-income families.

The method of amino acid sequence determination from the C-terminal amino acid is proposed and mass spectrometric identification of thiohydantoins described previously. In this paper was discussed the fragmentation of thiohydantoin-ring by deutero substitution and model tripeptide have been degraded through three stages each, with interpretable results. The conditions employed in this method are mild enough for biological materials. The main features of the method are the following. 1. Thiohydantoins were formed in a non-aqueous medium a mixture of acetic anhydride, acetic acid and ammonium thiocyanate. 2. Mass sepectra of thiohydantoins derived from 20 amino acids were obtained with a mass spectrometer, JEOL model JMS-06H. 3. Cleavage of peptidyl thiohydantoin was made with an acidic from of a cation-exchange resin. (Amberlite IR-120) 4. Separation of the cleaved thiohydantoin and the parent peptide less one amino acid moiety was made by chromatography on a Sephadex G-10 column. 5. The peptide fraction was concentrated by freezedrying. 6. Thiohydantoin derivative of carboxyl terminal amino acid residue was introduced with a direct inlet probe in methanol solution.

This study was conducted to investigate the food behavior during the childhood, the influence of food behavior on internalizing and externalizing behavior problems, and the pattern of influence of food behavior on behavior problem depending on children's age and gender. A total of 171 children aged 5 and 6 years were selected who attended 3 nurseries and 1 kindergarten in Seoul, and the survey data responded by teachers were analyzed. The results were as follows. First, children with higher levels of food behavior showed less internalizing behavior problems compared to those with lower levels of food behavior. The main effects and interaction of gender and age were not significant. Second, children with higher levels of food behavior showed less externalizing behavior problems compared to those with lower levels of food behavior. For hyperactivity, interaction of age and food behavior was significant, and age and the interaction of age and food behavior affected children's agression. Food behavior of children affects behavior problem and, therefore, children with better food behavior showed less behavior problems in the same circumstances.

Adolescents from stepfamilies have been considered as at-risk group of mental and behavioral problems. This study aims to determine whether there is a group difference of emotional or behavior disturbance between young people in step and non-stepfamilies and whether risk factors linked to emotional and behavior symptoms of young people in stepfamilies are different from those of girls in non-stepfamilies. The study used 'the Mental Health of Children and Young People in Great Britain, 2004 (MHCYP 2004)'. In the MHCYP 2004, the Rutter Problem Behavior Questionnaire, the Strengths and Difficulties Questionnaire (SDQ), and Child Behavior Checklist (CBCL) were administered to parents, teachers, and children drawn from young people aged 5-17 living in private households in England, Scotland (including the Highlands and Islands) and Wales. The total of 2,471 samples of aged 13 through 17 from them were selected for this study. The selected data was analyzed using SPSS. The findings showed group differences in emotional and behavior symptoms between young people in step and non-stepfamilies: Young people from stepfamilies were more emotional and have behavioral disturbances than those from nonstepfamilies. The result also confirmed the different risk factors associated with emotional behavior problems. The study supports that professionals need to develop effective treatment and preventive approaches designed for young people in stepfamilies who may have different risk factors different from those in non-stepfamilies.

This study examined the effects of young children's effortful control and emotional regulation, teacher-child conflictual relationships on young children's overt and relational aggression. The subjects of this study were 372, 3-5 years old children and their teachers. Young children's aggression, effortful control, emotional regulation, and teacher-child relationships were assessed by a teacher's report. The collected data were analyzed by t -test, Pearson correlations, and pathway analysis. The results were as follows: first, the boys' overt aggression was found to be greater than that of the girls,' while, there was no difference in relational aggression between boys and girls. Second, the boys' and girls' effortful control was found to affect the young children's overt and relational aggression indirectly through emotional regulation, and teacher-child conflictual relationships. For the girls, effortful control was found to affect overt aggression directly. Third, teacher-child conflictual relationships and emotional regulation were found to affect boys' and girls' overt and relational aggression directly and to mediate between boys' and girls' effortful control and overt and relational aggression. Further, for girls, emotional regulation was found to mediate between teacher-child conflictual relationships and overt and relational aggression. Additionally, effortful control was found to be the most important variable predicting boys' and girls' overt aggression, while a teacher-child conflictual relationship was the most important variable for boys' and girls' relational aggression.

This research examined the trajectories of peer rejection in preschool children. This study also investigated the gender differences in the intercept and slope of the trajectories for peer rejection along with the influences of aggression, withdrawal and language ability on the trajectories of peer rejection. A latent growth curve model investigated peer rejection in 3 to 5 year olds. Three hundred and thirteen 3-year-old children were recruited from five preschools and 14 daycare centers. The children's language ability was measured by a Wechsler Preschool and Primary Scale of intelligence verbal test and teachers completed measurements for aggression and withdrawal. A peer nomination inventory was used to assess peer rejection. Children were asked to nominate three classmates who they do not like to play with. The research findings showed that peer rejection decreased during the preschool years. Compared with girls, boys showed higher levels of peer rejection and a slower change rate of peer rejection. Girls who were aggressive showed high levels of peer rejection and a slow change rate of peer rejection. Moreover, girls who had a high levels language showed low levels of peer rejection and a slow change rate of peer rejection. These findings imply that language ability could be a protective factor of peer rejection for girls.

This survey's purpose was to understand the duties of the school dietitians' foodservice management and to identify the uses of preprocessed and processed food in Seoul Metropolitan area schools. The survey was distributed either via e-mail or in person to nutrition teachers and dietitians working at elementary, middle and high schools who participated in training sessions in Seoul, Gyeonggi and Incheon areas from December 2006 until June 2007. Four-hundred fifty-nine out of the total 760 schools that completed the surveys were analyzed. The following summarizes the main duties of school dietitians related to foodservice management: hygiene (100%), nutrition (99.8%), nutrition education (97.2%), cost (96.9%), and food production process control (96.3%). Preprocessed foods were ordered as the following: seafood (2.89) > poultry (2.78) > seeds (2.37), process foods comprised the following order: pastes (4.94) > kimchi (4.91) > dressing materials (4.50). Based on these results, elementary schools must improve methods for developing effective study materials for nutrition education which arc appropriate for each grade.
