The purpose of this study was to explore the effects of adolescent attachment to mothers and peers, self-esteem and impulse control on delinquency. The subjects were 624 eighth and eleventh grade students in Busan. The subjects rated themselves on questionnaires regarding attachment to mothers and peers, self-esteem, impulse control and latent delinquency. The major findings of this study were as follows; 1) Male adolescent delinquency increased with grade. But no grade difference was found in female adolescent delinquency. And male adolescent had more delinquency than female adolescent. 2) Grade had a direct and indirect effect through attachment to peers and impulse control on male adolescent delinquency and was the first positive contribution factor. Impulse control had a direct negative effect on male adolescent delinquency. Attachment to mothers had an indirect negative effect through self-esteem on male adolescent delinquency. Attachment to peers had an indirect negative effect through self-esteem and impulse control on male adolescent delinquency. Self-esteem had an indirect negative effect through impulse control on male adolescent delinquency. 3) Attachment to mothers had a direct and indirect effort through impulse control on female adolescent delinquency and was a first negative contribution factor. Impulse control had a direct negative effect on female adolescent delinquency. Attachment to peers had an indirect negative effect through impulse control on female adolescent delinquency. Grade had an indirect negative effect through impulse control on female adolescent delinquency. Self-esteem had no effect on female adolescent delinquency.

The purpose of this study was to explore the effects of the attachment to mothers and peers and the depression on the adolescent delinquency. The subjects were 516 eleventh grade students in the liberal and the commercial high schools in Busan. The subjects rated on questionnaires by themselves regarding the attachment to mothers and peers, the depression and the latent delinquency. The major findings of this study were as follows: 1) Adolescents in the commercial high school had more delinquency rate than those in the liberal high school. And the male adolescent had more delinquency rate than the female one. 2) The attachment to mothers and the kind of high school attended significantly predicted the male adolescent's depression. The attachment to mothers and peers significantly predicted the depression of the female adolescent. The relative influence of the attachment to mothers on the prediction of male and female adolescent's depression was the strongest among all the varibles. 3) The kind of high school had a first direct effect on the male and female adolescent's delinquency rates and was the first contribution factor. The attachment to mothers had both direct and indirect negative effect for female and an indirect negative effect for male on the adolescent delinquency rate through depression. But the attachment to peers had a direct positive effect on both male and female adolescent's delinquency. Depression had a direct effect on male adolescent delinquency.

The effects of environmental factors on adolescent’s socialization were examined according to the gender. Data were drawn from 1,412 adolescents. A hypothesized model was tested for male and female students separately by the links among housing, family conflicts, parent-adolescent relationship, family stress, peer relations, mass media, school atmosphere, consumption, consumer socialization, and adolescent’s socialization. There was no difference between male and female students in the predictability of the effects of environmental factors on internal and external socialization. For male students, the internal socialization was directly related to mass media, consumer socialization, peer relations, family stress, mother-adolescent relations, and school atmosphere. The external socialization was directly related to mass media, school atmosphere, consumer socialization, father-adolescent relations, housing, and mother-adolescent relations. For female students, the internal socialization was directly related to mass media, peer relations, father-adolescent relations, and consumer socialization. The external socialization was directly related to mass media, followed by consumer socialization, mother-adolescent relations, school atmosphere, housing, and peer relations. The findings are consistent with a growing body of literature showing that the environmental factors are related to male & female adolescent’s socialization.

The purpose of this study was to investigate the dietary habits, nutritional status, and serum copper and zinc concentrations of adolescent athletes. 50 high school adolescent athletes (29 male, 21 female) took part in physical education high school and 47 high school adolescent non-athletes (21 male, 26 female) in general high school. Questionnaires, anthropometric measurements, 24-hour dietary recalls and blood analysis were conducted. In the males, the mean height, weight and body fat percents of athletes and non-athletes were 174.0/172.9 cm, 67.4/68.3 kg, and 8.9/20.0% (p<0.001) respectively. In the females, the mean height, weight and body fat percents of athletes and non-athletes were 163.7/159.3 cm (p<0.01), 58.7/55.7 kg (p<0.05), and 18.6/30.1 % (p<0.001) respectively. In both male and female athletes, intakes of animal fat were significantly higher and intakes of vitamin C were significantly lower than those of non-athletes. There was no significantly difference in zinc and copper intakes between athlete and non-athlete groups. The average serum zinc level of male athletes was significantly lower than that of male non-athlete. The average serum copper levels of male and female athletes were significantly lower than those of male and female non-athletes. Based on these results, exercise may effect on zinc and copper utilization of adolescent. Further studies on zinc and copper nutrition of adolescent athletes were needed to understand more mineral nutrition and exercise.

This study tests the path model which examines how the variables of past and present family dynamics, school adjustment, filed life events affect the adolescents'depression which in tum influencing their suicidal ideation. In the path model, the exogenous varialbes were negative parenting experience in childhood, maladjustment history of the family (e.g., alcohol, divorce), present parent-adolesecent communication, school adjustment, filed life events were used, whereas the adolescent depression was used as the mediated variable. The endogenous variable was the adolescent suicidal ideation. The respondents of the survey were 635 adolescent who were 1st and 2nd grade of high school located in Seoul and Busan. Using SPSS for Windows, the path analysis was done for male and female adolescents separately, since female adolescents were found to report significantly higher degree of depression and suicidal ideation then were male adolescents. The results of the path analysis were as followings. First, for both the male and female adolescents, depression was the strongest predictor of their suicidal ideation. Also, school adjustment strongly affected the adolescents'depression as well as their suicidal ideation. Meanwhile, filed life events indirectly influenced the suicidal ideation only through the depression. Second, for the male adolescents, negative parenting experience in childhood affected both the depression and suicidal ideation, while the parent-adolescent communication directly affected the suicidal ideation. Third, for the female adolescents, maladjustment family history and negative parenting experience did not affect their depression, but the suicidal ideation. Meanwhile, parent-adolescent communication was a significant predictor of female adolescents'suicidal ideation as well as their depression. In conclusion, discussion on different path of male and female adolescents'suicidal ideation was provided.

The study evaluated the effectiveness of intervention for male adolescent smokers by making an assessment in terms of changes in food habits, nutrition knowledge, plasma catalase, superoxide dismutase(SOD), glutathione peroxidase peroxidase(GSH-px) activities and thiobarbituric acid reactive substance(TBARS) after Vit C supplementation and nutrition education. The subjects, male adolescent smokers, were assigned into four groups : Control group(19 students), education(Educ.) group(19 students), Vit C supplementation (suppl) group(19 students), and Educ. + Vit C suppl. group(19 students). The Educ. group and Educ. + Vit C suppl. group received nutrition education once a week for 2 weeks. The Vit C suppl. group Educ. + Vit C suppl. group received 500 mg ascorbic acid for 35 days. All data were collected before intervention and after intervention. Nutrition knowledge of those who received education increased, and the frequency of fruit and yellow-green vegetable consumption also increased. Plasma antioxidant enzyme activities were not different except for the SOD activity in the Educ. + Vit C suppl. group, which was significantly increased. The plasma ceruloplasmin level of groups that received Vit C supplementation was reduced more than any other groups, and the specific ceruloplasmin ferroxidase activity of groups that received Vit C supplementation was elevated more than other groups. These intervention programs had an impact on food habits, nutrition knowledge, plasma antioxidant enzyme activities, and plasma TBARS in male adolescent smokers. Various nutrition education programs must be implemented for adolescent smokers, and further studied are needed regarding sorts and amount of antioxidant nutrients and supplementation duration.

Background： Recently, adolescent obesity was increased and tended to become obese adults, facing increased risk for diabetes, cardiovascular disease. Even before reaching adulthood, adolescent obesity already was experiencing hypertension, dyslipidemia, and diabetes mellitus. The purpose of this study was to find prevalence of obesity of high school students in Jeju island and association between obesity and cardiovascular risk factors and association between childhood obesity and adolescent obesity. Method： The study subjects were 6,064 students of twenty-two high school in Jeju island and health survey data was gathered from high school health examination data and hospital health examination data from Aug. 1999 to Dec. 1999. Adolescent obesity was evaluated by ideal body weight method in 1998 and body mass index. Cardiovascular risk factors were checked total cholesterol, systolic and diastolic blood pressure, fasting blood sugar. In 1,534 students, obesity at primary school is checked by primary and middle school health record. Results： Prevalence of obesity in Jeju island high school students is 12.6% in male students, 13.3% in female students by ideal body weight method and 8.7% in male students, 8.5% in female students by body mass index. Prevalence of obesity of male students in city area and district area of Jeju island were each 12.9%, 10.3% and that of male students in city area was significantly higher. Prevalence of obesity of female students in city area and district area of Jeju island were each 12.9%, 14.2% and not significantly different. Prevalence of obesity of male students in general and commercial school group were each 13.9%, 10.1% and that of general school group was significantly higher. In female students, Prevalence of obesity general and commercial school group was not significantly different. Total cholesterol, systolic and diastolic blood pressure were significantly associated with degree of obesity in male and female students(p＜0.05) and fasting blood sugar was only significantly associated with degree of obesity in male students(p＜0.05). In 1,514 students checked by health record, Odds ratio of obesity at primary and middle school that at high school were 12.96∼22.77 and was significantly associated. Conclusion： Prevalence of obesity of high school students in Jeju island is very high and adolescent obesity was significantly associated with cardiovascular risk factors. Mostly childhood obesity tended to become adolescent obesity and program of control of obesity at childhood and adolescence is required.

Objective: To compare the electromyographic activity of masseter and temporal muscles between bruxers and nonbruxers in adult and adolescent patients. Material and Methods: The samples composed of the surface electromyography (EMG) recordings obtained from the orthodontic patients. Sixty-eight patients who had bruxsim habit (43 female and 25 male) were divided into four groups according to their age and gender. Control groups consisted of 79 patients who had not bruxism habit. EMG of the masseter muscle and anterior temporal muscle were recorded before treatment in clenching at maximum intercuspation. The ratio of temporal and masseter muscle activity (T/M ratio) was compared between bruxers and nonbruxers in adult and adolescent patients. Results: EMG of masseter muscle and temporal muscle were significantly higher in adult male bruxism group than control. T/M ratio in adult male bruxism group was significantly lower than in adult male nonbruxism group. However, there was no significant difference in T/M ratio between adolescent bruxism group and adolescent nonbruxism group. Conclusions: The balance in the activity of the masseter and temporal muscles may not differ between bruxers and nonbruxers during adolescent periods. However, in adult period, the masseter muscle activity against temporal muscle is greater in males with bruxism habit compared to non-bruxer.

This study explored moderating effects of parental attachment andparental monitoring in the relationship between stress and problem behavior among Korean adolescents. The Korean Youth Panel Study (KYPS) was used as sample data with a total of 2,503 11th grade students involved in this study. Results of hierarchical regression analyses showed that parental attachment (for both male and female adolescents) and parental monitoring (for male adolescents) played the role of moderators in the relationship between stress and problem behavior. That is, good parental attachment and monitoring reduced stress inducing problem behavior for male adolescents but only parental attachment reduced stress inducing problem behavior for female adolescents. Conclusions highlighted the importance of parents' role in the prevention of adolescent problem behavior.
