Objectives: The purpose of the study is to investigate remineralization effect according to application cycle of fluoride varnish in preschool children. Methods: The study subjects were fifty six children (92 teeth) having one or more early dental caries lesion. Fluoride varnish was applied to the primary area of maxillary and anterior mandibular teeth with the interval of one month, three months, and six months. Results: Dft index was 3.54 in male and 3.44 in female. The fluorescence loss(${\Delta}F$) value due to early caries lesions showed a significant difference in experiment groups I and II after the application of fluoride varnish, but there was no significant difference in experiment group III. After fluoride varnish application, there was a significant change in experimental group I and III. The maximum fluorescence loss(${\Delta}Fmax$) from early caries lesions showed a significant difference after application of the fluoride varnish in all three experiment groups of I, II, and III(p<0.001). Conclusions: Fluoride varnish should be recommended and applied to the children of high risk caries group in every three months.

Objective: The purpose of this study was to identify the longitudinal relationship between child maltreatment and adolescent suicidal ideation. Several studies suggest that child maltreatment is associated with adolescent suicidal ideation. However, these studies have not focused on the duration of child maltreatment. Methods: Participants were 420 adolescents (52.6% male; 47.4% female) involved in the Korea Welfare Panel Study. Data were collected via youth self-report in 2006, 2009, and 2012. A self-report assessment of children and youths' experiences of physical, emotional, or neglect had been surveyed longitudinally. Questionnaires on adolescent suicidal ideation were answered in 2012. A growth mixture model and multiple regression were conducted using Mplus 5.21. Results: The study results showed that 93.5% of the children had experienced no maltreatment; 6.5% had experienced increasing maltreatment longitudinally. The trajectory of increasing maltreatment was positively associated with adolescent suicidal ideation. Conclusion: These results show that children suffering from chronic maltreatment are subject to a high risk of suicide and therefore require continuous supervision and management.

The asthma is a clinical syndrome having three symptoms; dyspnea, wheezing and coughing, due to the narrowing of trachea in pulmonary system. Specially the asthma is common in children. The study was designed to identify the effect of Kinesio Taping Treatment as to asthmatic children. The Kinesio Taping Treatment was used on the Pectoralis major and Posterior diaphragm of twenty five asthmatic children(19 male, 6 female) for the period from September 1, 2001 to September 20, 2001. Peak expiratory flow rate(PEFR) for the condition of pulmonary function was measured using the Pocket Peak and wheeling and coughing symptom were measured using questionnaire. The results of this study are as follows: 1. There were statistically significant differences between before using the taping and after the kinesio taping increase of the PEFR(p<0.001). 2 There were statistically significant differences between before using the kinesio taping and after the kinesio taping improvement of the wheezing sign(p<0.001). 3. There were statistically significant differences between before using the kinesio taping and after the kinesio taping improvement of the coughing symptom(p<0.001).

Researches on children's traffic behavior have only focused on traffic accidents and the number of accidents, and therefore it's been impossible to deal with more broad field of study. In this research we can review the possibility of traffic accidents of children and provide them with traffic education. The goal of this research is to develop a device for measuring possibility of children in terms of traffic behavior. Around 600 elementary students of two schools involved in the pretest with 259 questions and about 3,500 students(junior level 53 questions & senior level 72 questions) involved in practical test. At the result of the research, junior level extracted 4 factors(Lack of behavioral control, Aggressive, Self-regulation, Impulsive Instinct) and 44 questions, and senior level extracted 4 factors(Lack of behavioral control, Depression, Sense-oriented, Aggressive) and 69 questions. We take the gender consideration in separate the groups whether the group has traffic behavioral problem or not. In these series of research, we got the standard score such as junior male student, 63 & female student, 50 and senior male student, 110 & female student, 99.

Objectives : Childhood depressive disorder one of the most prevalent chronic health conditions affecting school aged children. The objective of this study was to examine the prevalence and epidemiological characteristics of childhood depressive disorder in Korea. Methods : In this study, a survey was conducted of elementary school children in the Cheonan area from September 2009 to August 2010. A total of 12,084 children were included in the analyses. The primary measure of depression was the 27-item Kovacs' Children's Depression Inventory (CDI), the Korean Dupaul attention-deficit hyperactivity disorder Rating Scales (K-ARS), Autism Spectrum Screening Questionnaire (ASSQ) and Restless Legs Syndrome Questionnaire (RLSQ) were also administered. Results : The prevalence rate of childhood depressive disorder was 3.07%. The mean age was $9.21{\pm}1.81$ years for the control group (5,969 male, 6,054 female) and $9.91{\pm}1.83$ years for the depression group (CDI score${\geq}$22 ; 159 male, 210 female). Age, height, weight, and economic status were similar for the two groups. However, there were statistically significant differences in the distribution of sex. The distribution of school grade also differed between the two groups. Scores for CDI, K-ARS, and ASSQ in the depressive group were higher than those of the control group. Conclusions : This is the first large-scale population-based study to report on the prevalence of childhood depressive disorder in South Korea. Increased rates of childhood depressive disorder, as reported by primary caretakers, might reflect the increasing negative impact of environmental risk factors on neurobehavioral health. Longitudinal study of the prevalence of childhood depressive disorder should be considered for further evaluation.

The purpose of this study was to analyze the influence of a married adult on child-toparent and on parent-to-child financial supports. The data, derived from Korean General Social Survey(KGSS) was obtained from the Survey Research Center at Sung Kyun Kwan University. The samples included 367 married adult children who had more than one living parent. Multiple regression analysis was used to analyze the research model. The findings from the analysis showed that monthly household income had no significant impact on the financial supports that adult children provided to their parents or that the parents provided to their child. The expectation of financial supports from their parents in the future was a important factor that affected the level of female and male children's financial supports that they received from their parents. The level of instrumental supports from their parents and their parents-in-law did influence the level of financial transfers between them. These results showed that financial transfers between married adult children and their parents differed based on the children's attitude towards the supporting parents, and whether or not the children or parents had alternative resources available to them for financial supports. Moreover, the variation in financial supports and benefits showed complex differences based on the gender of the children, and based on whether the financial support was coming from the respondent's parents or their partner's parents.

This study was conducted to investigate effects of self concept of children consumers on consumption propensity of online items according to gender by considering that self, which means a thought on ownself, is expressed as online items in cyber space. Totally, 760 copies of the questionnaire were distributed and 716 ones were finally used as data for analysis in this study. The data were analyzed by using SPSS 14.0 and factorial analysis, Cronbach' ${\alpha}$, t-test, cross tabulation analysis and multiple regression were conducted. The results of this study could be summarized as follows. First, the factorial analysis performed to examine types of self concept found four factorial structures - justness, social, academic and family self. In addition, the factorial analysis done to determine compositional factors of irrational consumption propensity of children consumers showed three factorial structures - impulse buying, conspicuous consumption and imitative consumption. When the effects of personal variables, item-transaction variables and self concept on irrational consumption propensity of children consumers were investigated according to gender, significant factors affecting consumption propensity of both of the males and females were a monthly pocket money, time using the Internet and major transaction items. In addition, parents' permission for purchasing items, justness self and family self were found to be variables affecting consumption propensity in the male children. On the contrary, self concept of female children did not affect irrational consumption propensity.

This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.
