Objectives : This study explored the differences in their ego defense mechanisms between adolescents with conduct disorder and normal adolescents. Methods : Subjects were 35 adolescents with conduct disorder and 44 normal adolescents. The Ewha Defense Mechanism Test (EDMT), consisting of 200 items and 20 scales, was administered, to examine the defense mechanisms of both groups of adolescents. Results : Normal adolescents presented statistically significantly higher scores on the reaction formation, controlling, suppression, anticipation, dissociation, and distortion scales than did adolescents with conduct disorder. Zn addition, adolescents with conduct disorder used neurotic defense mechanisms of both neurotic and mature levels less frequently than normal adolescents did. Factor analysis revealed that, normal adolescents had higher scores on ego-expansive factor scales and behavior control factor scales thanadolescents with conduct disorder did. Conclusion : The results suggest adolescents with conduct disorder use mature and ego-expansive defense mechanisms less frequently than do normal adolescents.

The purpose of this study was to investigate emotional intelligence and stress coping styles of adolescents. The study also identified the differences of emotional intelligence and stress coping styles between normal adolescents and juvenile delinquents. The subjects in this study were 447 adolescents included 249 normal adolescents and 198 juvenile delinquents. The major findings as follows: First, there were significant differences on emotional intelligence between normal adolescents and juvenile delinquent. Normal adolescents had higher level of emotional intelligence. However there were no significant differences on stress coping styles except wishful thinking between normal adolescents and juvenile delinquent. Second, there were overall positive correlation between emotional intelligence and stress coping styles. However regulation of emotion showed negative correlation with stress coping styles. The result of Canonical Correlation revealed that emotional facilitation of thinking among five sub-domains of emotional intelligence was the best contributor to predict stress coping styles of adolescents.

Objectives: The aim of this study was to investigate the prevalence of metabolically obese, normal-weight (MONW) phenotype and the association between lifestyle factors and the risk of MONW in Korean adolescents. Methods: Normal-weight (BMI, 5th to 85th percentile) subjects with ${\geq}1$ metabolic abnormalities were categorized as MONW phenotype. Data from adolescents aged 12 to 18 years who have participated in the Korean National Health and Nutrition Examination Survey in 1998 (n=751) and 2008 (n=455) were analyzed. Physical activity and dietary intakes were assessed. Results: The prevalence of hypertension and hyperglycemia in 2008 decreased compared with that in 1998 (P<0.001) but the prevalence of abdominal obesity, hypertriglyceridemia and low HDL did not changed. The overall prevalence of MONW in Korean adolescents declined over 10 years (P<0.001). Adolescent boys and girls engaging regular exercise significantly increased over 10 years (P<0.01). Physically active adolescents had a lower risk of being MONW in 1998. Dietary intake patterns were not associated with a risk of MONW. Conclusions: The prevalence of MONW among Korean adolescents declined over 10 years which may be due to the decreased prevalence of hypertension and hyperglycemia. The risk of MONW would be lower in individuals who are physically active.

Purpose: The purpose of this study was to compare variables related to weight control between normal weight and overweight/obese female adolescents. Methods: This study is a supplementary analysis using a total of 293 female adolescents in Seoul. Data were collected through self-report questionnaires on the topics of stages of change, processes of change, and the decisional balance pertaining to weight control. Body weight and height were also measured. Results: There was a significant difference in the stages of change between the normal weight and overweight/obese groups. Of 12 processes of change, 9 processes were significantly higher in the overweight/obese group than in the normal weight groups. Also, female adolescents who were overweight or obese had significantly higher pros and eating efficacy scores comparing to those in the normal weight group. Conclusion: The findings of this study suggest that overweight/obese female adolescents, especially those in the action stage need supports to continue their weight control behaviors. In addition, a weight control program for female adolescents should emphasize their participation in physical activities in addition to their dietary control efforts.

Purpose: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. Methods: Study data on 12-18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. Results: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. Conclusion: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

The purpose of this study was to investigate the relationship between obesity and, erythrocyte SOD (superoxide dismutase) activity and serum antioxidant mineral (Fe, Zn, Cu, Mn and Se) concentrations of adolescents. Subjects were assigned to one of two groups such as obese ($BMI{\geq}25$, 32 boys, 24 girls) and normal group (18.5 < BMI < 23, 27 boys, 30 girls) Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age of the total subjects was 13.8 years. The mean weight (p < 0.001), BMI (p < 0.001) and body fat (p < 0.001) of obese were higher than those of normal group. There was no significant difference in nutrient intake between obese and normal groups. SOD activity of obese group was not significantly different from normal groups, in both males and females. However, in the males, serum Cu concentration of obese were significantly lower than those of normal group. In the females, Serum Mn concentration of obese were significantly lower then those of normal group. In the correlation analysis, BMI of the subjects had significantly negative correlations with serum Cu, Zn and Mn. To summarize the results, increase of obesity may lead to decrease of serum antioxidant minerals such as Cu, Zn and Mn.

Purpose: Height-specific blood pressure (BP) is the standard parameter used to diagnose childhood hypertension. However, there has been some argument that weight may be a better variable than height in the reference BP standards. Therefore, before assessing the BP status using the reference BP standards, a basic understanding of the fundamental association of weight and height with BP is required. Methods: In the present study, we analyzed the correlation of BP with height and weight in Korean adolescents (age, 10-19 years), using data from the Korean National Health and Nutrition Examination Surveys (2009-2011). Results: Systolic BP (SBP) was more closely correlated with weight than with height in the normal weight (body mass index [BMI], ${\leq}85th$ percentile) and overweight (BMI, >85th percentile) groups and in the normal waist circumference (WC, ${\leq}90th$ percentile) and high WC (>90th percentile) groups in both sexes. Diastolic BP (DBP) had a higher correlation with height than with weight in the normal weight and normal WC groups, whereas weight was more closely associated with DBP than height in the overweight and high WC groups in both boys and girls. Conclusion: In Korean adolescents, weight had a greater effect on SBP than height in both the normal weight and overweight groups. DBP was mainly affected by height in the normal weight group, whereas weight was the major determinant of DBP in the overweight group. Therefore, it may be necessary to consider weight in the establishment of reference BP standards.

The purpose of this study was to determine the differences in internet use motivations and problem behaviors among vocational high school students according to internet addiction and family system type. Five hundred vocational high school students from Daegu took part in the survey. The questionnaire survey consisted of an internet addiction self-assessment scale, a family system type scale, an internet use motivation scale, and a problem behavior scale. The data was analysed using MANOVA and Cronbach a, and the $Scheff\acute{e}$ test was used for post-hoc analysis. The major findings of this study were as follows: First, the study found significant differences in adolescent internet use motivation according to internet addiction. Adolescents in the high dangerous user group showed higher communicative, experiential, and addictive motivations than adolescents in potentially dangerous and normal user groups. Also, there were no significant differences in informative motivation according to internet addiction. Regardless of internet addiction, adolescents tend to use the internet to search for information and to solve problems. Second, there were significant differences in adolescents' problem behaviors according to internet addiction. More specifically, adolescents who were in the high dangerous user group displayed more problem behaviors toward their body, family, school, and society than adolescents in the potentially dangerous and the normal user groups. Third, an adolescent's family system type significantly influenced his/her internet use motivation. Adolescents from an extreme family showed higher communicative and addictive motivations than adolescents from middle and balanced families. Fourth, there were significant differences in the problem behaviors of adolescents according to family system types. Adolescents from an extreme family showed more problem behaviors toward their body, family, school, and society than adolescents from middle and balanced families.

This study conducted a comparison analysis of the differences by scope between juvenile delinquents, under sentence of juvenile protective disposition, and normal middle high school boys' self-esteem and sociality; it aims to search for the correctional policy to prevent juvenile delinquency. I conducted a survey, as a sampling target, of students (84) at Daedeok Juvenile Reformatory, located in Daejeon-si, Korea, and the normal middle high school boys (230). The results of analysis showed that in the analysis of self-esteem difference, juvenile delinquents were found high in the global self-esteem and school-academic self-esteem, but the normal adolescents were found high only in the scope of family-parents self-esteem. In leadership, a subordinate scope of sociality, juvenile delinquents showed the high result, and in independence and cooperativity, normal adolescents were found high. In conclusion, as the distinction between self-esteem and sociality is different by scope, depending on the individual's characteristic and environment, it suggests that the correctional policy through the customized plan is effective at preventing delinquency.

The purposes of this study were to investigate blood profiles and nutrient intakes of groups that are different in obese levels, and to find the credible predictor of insulin resistance. The subjects were classified as normal weight (%IBW${\leq}$ 110), obese without MS and obese with MS according to IDF definition of the risk group in metabolic syndrome (MS). Subjects of this study were included 137 (59 boys, 78 girls) free living children and adolescents (mean age $12.6{\pm}3.4$ years) in Gangneung area, South Korea. %IBW of normal weight (94.9%), obese without MS (123.8%) and obese with MS (131.5%) were significantly different among groups. HOMA-IR had positive correlations with TG (r = 0.634), waist circumference (r = 0.553), atherogenic index (r = 0.513), %IBW (r = 0.453) and ALT (r = 0.360), but showed negative correlations with HDL cholesterol (r = -0.417, p < 0.001). HOMA-IR showed positive correlation with polyunsaturated fatty acid intake (p < 0.05). The energy intake of obese with MS was 1762 kcal/day which was not significantly different from those of normal weight and obese without MS. Total fatty acid intakes of two obese groups were significantly higher than that of normal weight. The results of this study suggest that waist circumference and ALT as well as TG, atherogenic index and weight can be credible indices to predict the insulin resistance in children and in adolescents. In addition, nutrition education and adequate diet should be provided to prevent MS in children and in adolescents.
