The study was designed to assess the effect of iron and cereal supplementation on children's iron nutritional status in social welfare institutions. Dietary survey was carried out methods of food weighing and record by interview (n=74). A nutritional intervention study was carried out through supplementing iron supplements and cereal for 4 weeks in 4-12 years old children. Children received daily 40 mg elemental Fe as iron protein succinylate (n=23) and 3.6 mg elemental Fe as 100 g cereal (n=24), respectively. Blood samples were drawn before and after supplementation. Nutrients which children's intake was less than two-thirds of the RDA were vitamin A, vitamin B-1, vitamin B-2, calcium and iron. The mean daily intake of iron was 5.1 mg for male and 4.9 mg for female, and 52.3% for male and 45.4% for female of Korean RDA. The proportion of children with iron depletion assessed by TIBC (> 360 ${\mu}g$/dl) and serum ferritin (< 20 ng/ml) were 56.6% and 58.7%, respectively. The proportion of children with the iron deficient erythropoiesis assessed by serum iron (< 70 ${\mu}g$/dl), Hb (< 12 g/dl), Hct (< 36%) were 76.0%, 58.7%, 64.0%, respectively. After iron supplements treatment, Hb (p<0.001), Hct(p<0.001), serum iron (p<0.001), transferrin saturation (p<0.001) and serum ferritin (p<0.Ol) increase significantly and only TIBC decreased slightly. After cereal supplementation, in anemic children, Hct (p<0.001), serum iron (p<0.001) and transferrin saturation (p<0.001) were significantly increased. The effect of iron supplements and cereal supplementation in children with iron deficient erythropoiesis were more effective to improve the iron nutritional status than children with iron depletion. It was concluded that cereal supplementation program in anemic children was also effective to improve iron nutritional status.

The purpose of this study was to examine the general characteristics and the variety of family life experiences related to the life satisfaction of multicultural families with school-aged children. Data were drawn from the first wave of the Korean Children and Youth Panel Survey conducted in 2010 and developed by the National Youth Policy Institute. Further, the sample for this study consisted of 95 multicultural families who met the requirements. The data were analyzed by descriptive statistics, the t -test, analysis of variance, and multiple regression using SPSS ver. 18.0. The main results showed that family life experiences that were made up of 5 domains, specifically time, leisure, household economy, health, and child education had a broad range of levels. In addition, family life experiences differed according to the general characteristics of multicultural families with school-aged children, such as mother's employment status, number of children, father's employment status and education level, and family composition. Lastly, their life satisfaction was significantly predicted by the father's employment status and health, children's age, children's education, and leisure in the order of significance. These findings suggested the need to expand the social intervention range for multicultural families with school-aged children, particularly in terms of family leisure and children's school life adaptation.

The purpose of this study is to investigate children's perceptions of their own peer status and the variables that affect the perception. Four hundred boys and girls in grades five and six participated in this study. The participants were sampled from elementary schools located in two cities in Cheon-buk Province. Out of the 400 self-report questionnaires filled by the participants, 380 were used for the data analyses. The methods of analyses included basic descriptive categorical analysis (frequencies, means, percentages) as well as t-test, one way ANOVA, and multiple regressions. To summarize major findings from the analyses; first, a significant difference was found in children's aggression by father's job and mother's age, in children's popularity by school GPA, father's education, mother's education, and fathers job, and in children's isolation by father's age, father's education, mother's education, and father's job. Second, children's aggression was significantly dependent upon self-esteem, loneliness, family harmony, and family communication. Children's popularity was related with school grade, name satisfaction, body satisfaction, self-esteem, number of close friends, loneliness, family harmony family communication, parental love and acceptance, and perceived closeness to mother. Children's isolation was significantly associated with school grade, body satisfaction, self-esteem, number of close friends, loneliness, family harmony, family communication, parental love and acceptance, and perceived closeness to mother Third, according to the multiple regression analyses, it was found that highly aggressive children tend to report less family harmony, more loneliness, and a larger number of friends. Also, highly popular children tend to report less loneliness, larger number of friends, strong family harmony, and higher academic achievement. On the other hand, highly isolated children tend to perceive weak family harmony, more loneliness, and lower body satisfaction. Lastly, the overall peer status indicator depended significantly on family harmony, loneliness, self-esteem, academic achievement, body satisfaction.

The purposes of this study were firstly to assess the differences of conflict resolution strategies between friends according to children's peer status, and secondly to investigate the relationship of conflict resolution strategies measured by self-report, hypothetical interview, and observation methods. Thirty-four dayds in elementary 5th graders were selected according to peer status and friendship. Collected data were analyzed tv t-test and Spearman's correlation. The results of this study showed that children's conflict resolution strategies differed according to their peer status. Specially, popular children reported using and experiencing compromising/integrating strategies more than rejected children did. Rejected children reported using and experiencing dominating strategies more than popular children did. Secondly, there were meaningful correlations between compromising/integrating and dominating strategies, as measured by self-report, hypothetical interview, and observation methods. However, no relations emerged among avoiding, obliging, and intervention requesting strategies, as measured by self-report, hypothetical interview, and observation methods.

The purpose of this study was to investigate the causal resationships between children's learned helplessness, self-evaluation and the home environment which included the family's socio-economic status, parent's achieving pressure and maternal child rearing behavior. The results were as follows; The socio-economic status of home influenced on the parent's achieving pressure, maternal child rearing behavior and children's self-evaluation, but didn't influence children's learned helplessness. Parent's achieving pressure had a negative correlation with the maternal child rearing behavior and influenced children's learned helplessness, but did not influence children's self-evaluation. Maternal child rearing behavior influenced children's self-evaluation, but did not influence children's self-evaluation. Maternal child rearing behavior influenced children's self-evaluation, but did not influence children's learned helplessness directly. Children's self-evaluation had the strongest direct impact on children's learned helplessness. This was found to be a mediating factor between home environmental factor and children's learned helplessness.

This study investigated the agreement between 3 assessments of preschoolers' friendship: peer nominations, teacher nominations, and behavioral observations. The relationship between friendship, social status, social competence, and play behaviors was also investigated. The subjects were 44 5-year-olds. Teachers were asked to rate the children's social competence; play behaviors were observed during free play time. The results indicated high agreement between the 3 assessments. Popular children were more likely to have friends than other social status groups. Children without friends were more hesitant than children with friends. Children with friends were more accepted by peers and engaged in cooperative social play more than children without friends.

Purpose: To investigate the dental health status of kindergarten children according to their oral health behavior. Method: The subjects were 172 kindergarten children aged 5. A structured questionnaire was used for dental health behavior and oral health status were examined by dentist and bacteria in salivary. Result: 1. Mean score of oral health behavior of children was 4.69 points (SD1.65) with the highest score being 13. No significant differences were observed according to sex, except using tooth paste. A total 71.5% of subjects brushed their tooth twice a day, 9.9% of them once a day, 18.6% of them three times a day, 19.2% of children brushed their teeth after breakfast and lunch, 89.5% of then after dinner, 5.8% of them before going to bed, 18.6% of children brushed correctly, 79.7% of them used tooth paste with fluorine, 3.5% of them regularly examined oral cavity, 84.4% of them took cariogenic food without any restrain, 67.1% of them were observed with oral cavity by their mother. 2. Streptococcus mutans and lactobacilli in the saliva was $3.66({\times}106CFU/m{\ell})\;and\;1.05({\times}103CFU/m{\ell})$, respectively. No significant differences were observed according to sex, while lactobacilli were significantly lower in those children who had regular dental examinations. 3. The index of plaque was 1.56 and the boys were significantly higher than the girls. The mean dft was 4.99. No significant differences were observed according to sex, while the children whose oral cavity was observed regular were significantly lower than those who were not observed. Conclusion: As a whole the practice of oral health behavior of the kindergarten children was poor, and regular dental examinations and oral cavity observations affect their dental health status. These results suggest that intensive dental health education was needed not only for the pre-school children but also their parents and teachers.

The study examined the characteristics of the relationship of home environment variables and children's social development. Two studies were conducted ; Study I examined (1) the correlation of home environment variables and children's social ability and (2) the predictability of home environment variables for children's social ability by children's age. Study II investigated the causal relationship among the variables which are supposed to affect children's social ability. The subjects of this study were 240 children at age four, six and eight attending nursery schools, kindergartens and elementary schools and their mothers. Instruments included the Inventory of Home Stimulation (HOME), the Inventory of Sociodemographic Variables, social maturation scale, and the social-emotional developmental rating scale. The results obtained from this study were as follows : 1) Home environment variables had a positive correlation with children's social development at age four and six, but at age eight, only HOME variables had a significant positive correlation with children's social development. 2) The home environmental variables that significantly predicted children's social development differed according to children's age. That is, play materials, economic status of the home, and parent education were predictive of children's social development at age four, while parent's education, fostering maturity and independence, and play materials were predictive at age six. Fostering maturity and independence, aspects of physical environment, and economic status of the home were predictive at age eight. 3) The causal model of home environment effect on children's social development was formulated by exogenous variables (parent education and economic status of the home) and endogenous variables (direct stimulation, indirect stimulation and the emotional climate of the home). 4) The results of the analysis of the causal model showed that the variables that have a direct effect on children's social development differed according to children's age. That is, direct stimulation had more effect on children's social development at earlier ages, and indirect stimulation had more effect on children's social development at later ages. Among socio-demographic variables, parent's education was most closely related to children's social development. The amount of variance that explained children's social development decreased with increase in children's age.
