The menarcheal age of Korean women has been rapidly decreasing for the last 50 years, and the average menarcheal age of women born in the 1990s is approaching 12.6 years. In addition, interest in early puberty has been increasing recently owing to the rapid increase in precocious puberty. Generally, out of concern for short stature and early menarche, idiopathic central precocious puberty in female adolescents is treated with gonadotropin-releasing hormone analogs. Studies to date have described the association between early menarche and psychosocial problems such as delinquency and risky sexual behavior, as well as physical health problems such as obesity, diabetes, cardiovascular diseases, and breast cancer throughout the lifespan of women. However, the pathophysiological mechanism underlying this association has not been clarified thus far. In this article, we review and discuss the existing literature to describe the current understanding of the effects of early menarche on the physical and psychosocial health of adolescent girls and adult women.

The authors reviewed the child and adolescent's traumatic experiences expressed in movies through late 1950s to year 2002. The movies are roughly classified by 3 categories based on the methods that used to express protagonist's experience and to uncover the meaning that is implied, that is, an important motive of growth, a metaphor of socio-political issues, or merely an event to develop a drama. Movie is a product of repetition compulsion and an activity like symbolic play between creator and spectators through screen, which enables a kind of corrective emotional experience. The curative elements in movies were also reviewed. The authors suggest the importance of mutual communications between movie creators and psychiatrists because media images about psychiatric issues can make internal stereotypes in conscious and unconscious mind of spectators.

Background: Incorrect postures of adolescents caused by the use of smart devices have been noted as a factor causing spinal diseases. Objectives: To examine the effect of joint mobilization and stretching on Cobb's angle and respiratory function in adolescent idiopathic scoliosis (AIS). Design: Cluster-randomized controlled trial. Methods: A total of 22 subjects with AIS were enrolled. They were allocated to two groups: the joint mobilization (n=11) and the stretching (n=11). All interventions were conducted for 30 minutes, three times a week for six weeks. Outcome measures were the Cobb's angle and respiratory function. The Cobb's angle and respiratory function measured using the X-ray and Micro-Quark. Results: Joint mobilization group showed significant differences in Cobb's angle and respiratory function, but stretching group showed significant differences Cobb's angle. The differences in peak expiratory flow (PEF) between the two groups were significant. Conclusion: This study proved that joint mobilization is a more effective intervention for AIS to improve Cobb's angle and respiratory function, when compared to stretching.

The purpose of this study was to investigate the nutritional status of serum minerals, ceruloplasmin, and ferroxidase activity in female adolescent students according to their smoking status. The subjects were 87 non-smokers and 88 smokers, who were female high school students. The smokers were divided into tow groups by smoking status, 35 light smokers(pack-year<1) and 53 smokers(pack-year$\geq$1). The serum concentrations of 6 minerals were determined by ICP emission spectroanalyzer. The serum concentration of ceruloplasmin and ceruloplasmin ferroxidase activity were determined. All data were statistically analyzed by SAS PC package program. The serum minerals concentrations of all subjects were in a normal range. There were significantly differences in the concentrations of serum copper, zinc, magnesium, and phosphorus by smoking status while there were no significant differences in the concentrations of serum iron and manganese by smoking status. Furthermore there were no significant differences in the ceruloplasmin concentration and ferroxidase activity by smoking status. In conclusion, smoking status altered the serum levels of some minerals in healthy young women. The minerals levels in light smokers with relatively short pack-year(pack-year<1) were altered compared to those in non-smokers or smokers. This finding seemed to be consistent with the results of previously published data related to antioxidant vitamin and lipid peroxide levels. However further research is needed to clarify these findings in female adolescent smokers.

Objectives: This study identified how personal characteristics, family environment, governmental policy for the prevention and cessation of smoking might influence on adolescent smoking. Methods: This study used data from the 2006 Korea Youth Risk Behavior Web-based Survey of 71,404 middle school and high school students, giving a response rate of 90.9%. We selected 61,508 adolescents subjects of the final analysis without missing data on independent variables and dependent variables which are used in this study. This study used $\chi^2$ tests and logistic regression models. Variables were added to the regression model in three groups using a hierarchical approach.Results: Adolescents were significantly more likely to become current smokers if they were boys, were in a higher grade, and had lower academic achievement. Adolescents experiencing stress and depression were associated with increased risk of current smoking. Adolescents with single parents or students of non-living with parents comparing with students of living with parents showed the high possibility of smoking. Lower father's education was associated with increased likelihood of current smoking. Adolescents who were exposed to smoking at home were more likely to smoke. Adolescents without contacting with the antismoking media campaign was associated with increased likelihood of current smoking. Conclusion: Promoting antismoking media campaigns targeted at adolescent is required, and the smoking prevention education which are proper for subjects are required. Proper plans which could decrease the exposure of secondhand smoking should be established.

Purpose: Adolescence is a developmental period characterized by the rapid growth of the musculoskeletal system, which is important for maintaining correct posture. Incorrect posture, lack of exercise, and reduced physical activity can cause spine deformities and affect lifelong health. This study was designed to evaluate the application and effect of a program for improving adolescents' musculoskeletal health. Methods: A quasi-experimental pilot study was conducted with 13 male and 20 female middle and high school students, with an average age of 15.39 years. Their general characteristics and physical measurements were obtained. The program consisted of group exercises (60 minutes, once per week), gait pattern monitoring, and online communication. A paired t-test and Wilcoxon signed-rank test were used to examine the program's effect. Results: Overall posture habits improved, and the total musculoskeletal index decreased; however, these results were not statistically significant. Conclusions: The devised program was effective in improving musculoskeletal imbalance. Therefore, effective programs and health devices should be developed to help adolescents maintain correct posture and encourage and support continuous participation in such programs.

The purpose of the study is both to develope the group counseling program applying Reality Therapy, by which positive body image could be conceived by adolescent women, by helping them identify their bodies as what they are, and then admit their real bodies, and also find out some practical methodologies of self-esteem, and to verify the program to show how effectively this program can be applied to them. Data were collected by self-reported questionnaires(body image and depression) from 59 high school girls in Seoul who were selected by criteria of this study, from the 1st of September to 10th of November, 2000. The experimental group participated in the group counseling by applying Reality Therapy with 8 sessions for 4 weeks. Descriptive statistics, homogeneity test, hypothesis testing, reliability were performed statistically by utilizing SAS pc program, and additionally the reaction due to the change of body image by adolescent women was also analyzed. The results drawn through the present study are as follows: 1. A hypothesis that 'adolescent women who participated in the group counseling program by applying Reality Therapy may get higher points on body image than adolescent women who did not participated' has been adopted (t=6.73, p=.000). 2. A hypothesis that 'adolescent women who participated in the group counseling program by applying Reality Therapy may get lower points on depression than adolescent women who did not participated' has been adopted (t=5.28, p=.000). 3. After applying the group counseling program, the degree of depression for upper group who obtained higher preliminary points on depression has decreased rather meaningfully more than that for lower group who obtained higher preliminary points(t=5.58, p=.000). 4. Reactions associated with positive change in body image of adolescent women who participated in the group counseling program by applying Reality Therapy has been shown to be body acceptance, enhancement of self-esteem, and change of value judgment of beauty. 5. The difference in the motivation and attitude of each group has been observed, by analyzing the reactions obtained from those who show the highest change of body image and those who show the lowest change of body image through the group counseling program by applying Reality Therapy. According to the present studies, it can be concluded that the group counseling program by applying Reality Therapy has turned out as an effective strategy for nursing intervention for adolescent women, by helping them form positive body images and reducing depression.

Objectives: According to the 10th revision of the International Classification of Diseases, the main categories of tic disorders (F95.0, F95.1, and F95.2) follow a diagnostic hierarchy based on the duration and diversity of tic symptoms. The present study investigated the use of this diagnostic hierarchy in real-world clinical practice. Methods: Based on the National Health Insurance Service-National Health Information Database, the diagnosis of transient tic disorder (F95.0) made after a diagnosis of chronic motor or vocal tic disorder (F95.1) or Tourette's syndrome (F95.2) and diagnosis of chronic motor or vocal tic disorder (F95.1) made after a diagnosis of Tourette's syndrome (F95.2) were referred to as type A errors. The diagnosis of transient tic disorder (F95.0) repeated after a period of >12 months was referred to as type B error. Demographic and clinical differences according to the diagnostic error types were analyzed using analysis of variance, Student's t-tests, and chi-squared tests. Results: Most participants (96.5%) were without errors in the diagnosis of tic disorders. Higher proportions of males (p=0.005) and antipsychotic prescriptions (p<0.001) were observed in patients with type A or B diagnostic errors. A higher proportion of health insurance holders was observed among those with type A errors (p=0.027). Conclusion: Errors were absent in majority of the tic diagnoses in real-world clinical practice in terms of the diagnostic hierarchy.

Purpose: The purposes of this study are as follows: Identifying the types of bullying; describing the relationship among social support, parent-adolescent communication and bullying types; identifying factors influencing the bullying. Method: 374 subjects were 5-6th grade students of two elementary schools in Daejeon. We collected the data from June 10 to October 29, 2002. The data were analyzed by using the frequency, ANOVA, pearson's correlation and stepwise multiple regression in the SPSS. Result: The 7 % of the subjects were found as bullies and another 23.8 % as victims, while 25.9 % were found as bully-victim group. The number of the victims in peer-support got less than in the normal or bully group. In the correlation analysis, the score of bullies, victims and bully-victim group were reversely-correlated with the social support. The score of victims was reversely-correlated with the mother-adolescent communication. In regression analysis, the social support influenced significant effects on both the bullies and victims. Conclusion: Findings indicated that the health professionals need to identify social support and parent-adolescent communication according to bullying types. Therefore, adequate approaches for the three independent groups of bullying are necessary.

Objectives: Adolescent suicide, a major cause of adolescent death, is affected by various factors, including attitudes toward suicide. This study investigated the association between parenting style and adolescents' attitudes toward suicide and the mediating role of attitude toward suicide between parenting style and suicidal ideation. Methods: We surveyed 1,071 adolescents from eight middle schools in Incheon, Korea. The survey included sociodemographic information, attitudes toward suicide, perception of parenting style, depression severity, and suicidality. Results: Students in the authoritarian parenting group had a more permissive attitude toward suicide compared with the democratic and permissive parenting groups. These students considered that suicide is justified in certain situations and that choosing suicide is an individual's right. They also had a negative attitude toward talking about suicide or intervening in others' suicide. This association remained statistically significant after adjusting for the impact of confounding factors that could affect attitudes toward suicide, except for suicidal processes and preparedness to prevent suicide. In the mediation analysis, we observed that some factors of the attitudes toward suicide mediated between authoritarian parenting attitudes and suicidal ideation, namely, suicide as a right, preventability, suicide as normal/common, preparedness to prevent suicide, and resignation. Conclusion: This study revealed the significant impact of parenting style on children's attitudes toward suicide. Educating parents about the appropriate parenting attitudes-sympathetic and rational-can help prevent youth suicide.
