Objectives : We conducted this study to investigate the relationship between sleep duration and body mass index (BMI), in Korean children. Methods : We performed a cross-sectional analysis of data collected on 3,639 boys and girls (aged 7-12) in Daegu, Korea. The data included each child's age, sex, weight, height, extracurricular activities, bedtime, wake-up time, sleep latency, total sleep duration, parents' occupations, and parents' educational levels. The relationship between sleep duration and each variable was examined via analysis of variance (ANOVA). Results : The analysis showed an association between short sleep duration and high BMI. Boys showed a graded inverse relationship between sleep duration and BMI. However, there was no significant corresponding result for girls. In the total sample, hours of computer use, time when the computer was turned off, time when the television was turned off, mother's bedtime, and hours of extracurricular activity were associated with longer sleep duration. No association was found between sleep duration and hours of watching television, child's wake-up time, or educational level of the parents. Conclusion : The results of this study show an inverse relationship between a child's sleep duration and BMI；thus, children with shorter sleep duration tend to have higher BMIs.

Purpose: This study was done to identify factors associated with fatigue in pediatric patients with cancer in order to develop nursing interventions for this population. Methods: The participants were 95 pediatric cancer patients admitted to a university medical center in Seoul, Korea, and 95 parents. The $PedsQL^{TM}$, Multidimensional Fatigue Scale developed by Varni (2002) was used to measure fatigue. Data were analyzed with the SAS program and t-test, analysis of variance (ANOVA), Pearson correlation coefficients, and multiple regression were used to identify the association of factors with fatigue. Results: The mean score for fatigue was 30.42 in the pediatric cancer patients and 34.77 in the parents. Fatigue was higher in patients living with a single parent, in patients whose father had a lower education and those patients with a fever. Pain, frequency and intensity of nausea and vomiting, depression, anxiety, and disruption of usual activity were positively associated with fatigue. The predictive factors for fatigue were disruption of usual activity, depression and living with or without parents. Conclusion: Pediatric patients with cancer experienced fatigue during their diagnosis and treatment. Of the multiple factors associated with fatigue, the association between disruption of usual activity and fatigue was the highest indicating a need to be concerned with this factor when providing interventions to alleviate fatigue.

Objectives : The physical activity of Korean adolescents and its distribution based on social characteristics have not yet been fully assessed. This study intends to reveal the distribution of physical activity by its subgroups and offer possible explanatory variables. Methods : The 3rd Korea Youth Risk Behavior Web-based Survey was analyzed for this study. The appropriateness of physical activity was defined by Korea s Health Plan 2010 and physical inactivity was assessed independently. Family affluence scale, parents education levels, subjective economic status, grade, and school location were considered explanatory variables. All statistical analysis was conducted using SAS ver. 9.1. Results : The proportion of participants engaging in vigorous physical activity was high in males (41.6%), at a low grade (38.5%), within the high family affluence scale group (35.5%). The distribution of participants engaging in moderate physical activity showed similar patterns, but the overall proportion was lower (9.8%). Low family affluence and students with lower subjective economic status reported a higher prevalence of physical inactivity. In multiple logistic regression analysis for physical activity, significant factors included family affluence scale (p<0.05). For physical inactivity, family affluence scale, parents education levels, and subjective economic status were included as significant factors (p<0.05). Conclusions : The results suggest that the physical activity and inactivity of adolescents may be affected by socioeconomic variables, such as family affluence scale. This implies the need to take proper measures to address these socio-economic inequalities.

Objectives：This study was conducted to evaluate the effects of the attachment promotion program which was designed to promote attachment between autistic children and their mothers. The program was consisted of play activity centered mother-child interaction, educational activity for mothers by lecture, video-feedback session, and emotional supports. Methods：The subjects were consisted of 11 pairs of mother and child(7 for participant group：PG, 4 for non-participant group：NPG), who were 2-4 years-old autistic children. The data were collected by video-taping, behavioral observations, and analyzed by Wilcoxon Rank(Sign) Sum Test and Content Analysis. Results：The total attachment score increased from pre test to post-test of PG was significantly higher than that of NPG. The scores of attachment behaviors indicating proximity, mutuality and affect increased significantly(p<.05), while some behaviors indicating synchrony and jointattention did not. Especially the affectionate behaviors of PG demonstrated the most notable changes and they became more active, voluntary and reciprocal. After the program, the mother's nurturing behaviors of PG increased more than that of NPG, with no significant difference between two groups. The mother's behaviors to her child of PG became more child-centered, positively responsive, supportively expressive. As the attachment was promoted, there were also positive changes in the children's autistic behaviors with a great deal of individual differences. Conclusion：Our findings suggest that Mother-Child Attachment Promotion Program could be an effective early intervention model for autistic children.

Objectives : Characteristic symptoms, including hyperactivity and easy distractibility, in children with attention-deficit hyperactivity disorder (ADHD) suggest that their brain status, even at rest, might differ from that of healthy children. This study was conducted in order to determine whether resting state brain activity is compromised in medication-naive children with ADHD. Methods : Twenty medication-naive children with ADHD (mean age $10.3{\pm}2.5$) and 28 age- and gender-matched healthy volunteers (mean age $10.3{\pm}2.0$) underwent measurements for resting state brain activity using functional magnetic resonance imaging (fMRI). Among resting state related-independent components (RSICs) extracted from fMRI data using independent component analysis, a significant difference in RSICs was observed between groups, using a mixed Gaussian/gamma model. Results : Except for IQ, which was higher in the healthy control group, no demographic difference was observed between the two groups (p<.001). Significantly less activation of one RSIC, which includes the bilateral precuneus/posterior cingulate cortex, occipito-temporal junction, and anterior cingulate cortex, was observed in the ADHD group, compared with the control group (p<.05). Conclusion : An abnormal RSIC, posterior default mode network (DMN), was observed in the medication-naive ADHD group. Results of our study suggest that abnormality of posterior DMN is one of the main pathophysiologies of ADHD.

The purpose of this study is to analyze the acceptance and interpretation of pop musician's image in the Korean youth subculture, Fan Costume play(Fancos). Fancos subculture took the most active attitude to accepts of the pop musician's image and therefore was assumed to have various and differential acceptance aspects. The ethnographic method was used in order to approach more closely from their point of view. The cultural activity of Fancos subculture was imitation and reappearance of pop musician's appearance. Actually Fancos is a kind of fan-culture which idolized Korean pop music star. The acceptance of musician's appearance in Fancos is found out in two aspects. One is passive acceptance aspects that inforces conformity of star fashion and follows servilely ideal body image which promoted by cultural industry. The other is unique acceptance aspects that Fancos members interpret the musician's image in their own way. Those members experience pleasure through their own meaning. And homology of their appearance makes a distinction between of themselves from other youth and intensifies their group identity. As above analyzed, Fancos subculture has differential acceptance of pop music star's image comparing to other youth and even their stylistic appearance reflects not only their fandom but also their own meaning. Consequently, pop musician's image as a popular cultural text is accepted not equal to all populace but dissimilar along with contexts and trails of the acceptance group.

The purpose of this study is to identify the effects of adolescents' experience activity satisfaction on their life satisfaction, and verify the mediating effects of sense of community between the two factors. For this, analysis has been conducted using Korean Children and Youth Panel Study (KCYPS, Ed. 6). Analysis were performed using the SPSS 24.0 program to verify the mediating effect, and the Sobel test was performed to analyze the statistical significance of the mediating effect. First, it was analyzed that the experience activity satisfaction had a statistically significant positive (+) effect on sense of community. Second, it was found that the adolescents' experience activity satisfaction had a significant positive (+) effect on the life satisfaction. Third, it was confirmed that snse of community had a positive (+) effect on life satisfaction, and at the same time, it was found that adolescents' experience activity satisfaction had a significant positive (+) effect on life satisfaction, so sense of community had a partial mediating effect.

This study intends to suggest basic data for the activation of rural activities in dietary life education, through a survey of adolescents on rural activities in dietary life education. It was found that 63.2% of subject students had the experience of rural activities; and that as many as 35.2% among the students who experienced rural activities participated in the activities 5 times or more. And the survey showed that rural activities were led most frequently by a teacher in charge (37.9%), and rather rarely by a nutrition teacher (15.4%) or an expert in dietary life education (7.7%). As for food ingredients that adolescents experienced during rural activities, they were composed of easily available good cookers that are common in the Korean diet, and, among them, vegetables were experienced most, followed by cereals and fruits. On the other hand, as for food ingredients preferred by adolescents, it was found that boy students preferred meat, while girl students preferred fruits. And as for improvements in dietary life, it was found that making efforts to have good dietary habits had the highest score, which shows that rural activities contributed to the improvement in adolescents' dietary life. Therefore, given the fact that rural activities go some way towards improving adolescents' dietary life, it is advisable that more opportunities for experiencing rural activities be provided to adolescents in the future so as to help them have good dietary habits.

Objectives: The purpose of this study was to evaluate the effect of nutrition education using materials based on social cognitive theory. Education topics focused on improving health-related and dietary self-awareness and behavior capability in adolescents. Methods: Participants were recruited from a middle school for girls; 67 students (educated group, n=34 and control group, n=33) participated. The education group received 12 lessons in club activity class. Self-administered surveys were conducted for each group before and after the nutrition education program. The questionnaires consisted of variables such as self-efficacy, outcome expectation, outcome expectancy, knowledge, and dietary practices based on the social cognitive theory. Education satisfaction was evaluated using a five-point Likert scale for two sections: a) teaching and learning and b) education results. The data were analyzed using a t-test and Chi Square-test (significance level: p < 0.05). Results: In the education group, post-education, there were significant differences in self-efficacy (p < 0.05), knowledge (p < 0.01), and dietary practices (p < 0.05), whereas outcome expectation and expectancy did not show any significant differences. None of the variables showed any significant differences in the control group. Educational satisfaction scores were $4.38{\pm}0.12$ (teaching and learning) and $4.14{\pm}0.15$ (education results). Conclusions: This study showed that improving adolescent's awareness and behavior capability has a positive effect on their dietary practices. Moreover, this study suggested that a theory-based determinant should be considered to improve dietary behavior among adolescents.
