Purpose. This study was conducted to understand the degree of internet addiction tendency and to find out the factors influencing this addiction tendency among middle school students in Gyeong-buk area. Methods. A total of 450 middle school students in the Daegu and Gyeong-buk area were surveyed in this study. Data collection was conducted through the use of questionnaires. Results. Internet addiction among middle school students was relatively low (Average user). In the overall ratio distribution, however, students who were classified as either addicted or at risk of addiction accounted for a high percentage, 27%. A positive correlation was found between Internet addiction and Internet expectation, depression and parent control over Internet use. A negative correlation was found between Internet addiction and interpersonal relationship, parent support and self-control. Multiple regression analysis revealed that the most powerful predictor of Internet addiction tendency was depression. Conclusion. Through the above results, it would be necessary to develop an Internet addiction prevention program for adolescents taking into account for the psychological factors such as depression and Internet use habits. In the future study, the need assessment will be useful for developing this prevention program.

Fear of missing out (FoMO) refers to the desire to stay continually connected with what others are doing because they are afraid of missing the flow or not being included. Although FoMO has been recently proposed as a widespread phenomenon within social media, there has been few empirical research by which mechanism FoMO leads to social networking service (SNS) addiction. Therefore, this study examined whether FoMO mediated the relationship between adolescents' attachment and SNS addiction proneness. A total of 517 middle and high school students participated in the study and completed self-report questionnaires. Results showed that FoMO partially mediated the relationship between adolescents' parental attachment and SNS addiction proneness, whereas the relationship between adolescents' peer attachment and SNS addiction proneness was fully mediated by FoMO. These results suggest that unstable attachment might contribute to SNS addiction through FoMO, especially in case of peer attachment. Lastly, we discussed theoretical and practical implications of this study and suggestions for future research.

Objectives : The purpose of this study was to assess anger of middle school adolescents in an urban community using State-Trait Anger Expression Inventory (STAXI)-Korean and Korean Child Behavior Checklist (K-CBCL), and to determine whether specific anger expression of adolescents is associated with certain psychopathology including depression. Methods : Data were collected from 395 middle school students and their parents in Incheon city. The students completed the STAXI, Children's Depression Inventory, Korean version of Mood disorder Questionnaire, and Conners-Wells' Adolescent Self-Report Scale (Short Form), and their parents completed the K-CBCL. Results : No significant correlation was observed between aggression subscale K-CBCL and each scale of the STAXI, except anger out (r=0.704). The scores for STAXI total and respective scales were significantly higher for female students than male students. A stepwise logistic regression model was used to explore the possible predictors for depression in adolescents and lower anger control and higher anger suppression were found to be predictors for depression in adolescence. Conclusion : There is a possibility of a large discrepancy between anger that the adolescents actually feel and parents' judgment of their children's anger. It must be considered in assessment of adolescent anger and use of further structured interviews is necessary. In addition, it may be useful to consider the anger expression style in adolescents who report depressive symptoms.

Although adolescents' obesity prevalence increases recently in Korea due to Westernized dietary life, according to social and economic development, and physical activity decline, distorted body image and improper dietary habits are prevalent, because of excessive obsession with weight control, deriving from psychological impacts including appearance supremacy. This study conducted a survey on health oriented awareness and attitude related with dietary habits targeting adolescents, such as high school students and college students, younger than 24, from May 11 to May 29, 2015. In this study, 280 questionnaire copies were collected out of 300 distributed questionnaire copies, and used 269 copies as analysis data, except 11 copies of which responses were inadequate. The results of this study are as follows: First, the high school students showed higher dietary regularity than the college students. Especially, 95.5% of the college students showed very high irregularity of lunch, compared with just 4.5% of the high school students. Second, the adolescents showed distorted perceived body image in comparison with body mass index (BMI). As a result of examining BMI relationship, according to one's own perception on body type, 28.6% of the respondents perceived themselves fat, despite normal BMI, and 40.4% of the respondents perceived themselves normal, despite low BMI. Third, health behavior activities level was higher, as the regularity of breakfast (B=1.093), lunch, (B=0.650), and dinner (B=0.765) was higher. The variable affecting the most ( ${\beta}=0.372$) was the regularity of breakfast. As interest in weight control was higher, health behavior activities was lower. Because over-interest in weight control may be linked with improper dietary habits or weight control, a caution is needed. The results of this study are expected to be utilized as the basic data for the policy and health-oriented program development to improve adolescents' health behavior practice.

The purpose of this study is to verify the causal relationship between depression and aggressiveness among adolescents. The 4-year longitudinal data collected from 2,670 4th grade elementary school students by the Korean Youth Panel study was used in this study. From the analysis result using the Autoregressive Cross-Lagged Model, the depression and aggressiveness in adolescents were continued from elementary school 4th grade to middle school 7th grade in significant stability. In addition, the previous aggressiveness turned out to have significant positive effect on the later period depression. Similarly, the previous depression had significant effect on the later aggressiveness, but the direction was negative. This means that the adolescents's depression increases as their aggressiveness increases, but as the depression increases, the later aggressiveness of the adolescents decreases. There were no differences between girls and boys within the relationship of these two variables. Finally, the implication derived from the results, the limitation of this study, and suggestion for following studies were presented.

Obesity during childhood is a dominant risk factor for noncommunicable diseases (NCDs), and is itself considered a disease that needs to be treated. Recently, the growth in childhood obesity in Korea has become stagnant; however, two in every ten children are still overweight. In addition, 60% or more of overweight children have at least one metabolic syndrome risk factor. Thus, childhood obesity should be controlled through lifestyle modification. This paper reviews studies of the modifiable risk factors of obesity in Korean children. According to the life-course approach, preschool-aged children (<5 years) are influenced by their parents rather than individual habits because they are under mostly parental care. Elementary school-aged children (6 to 11 years) are affected by overlapping individual and parental effects. This may mean that the establishment of individual behavior patterns begins during this period. The conditions of poor eating habits such as skipping meals, eating out, and high fat intake, along with low physical activity, facilitate increased obesity among adolescents (12 to 18 years). Notably, adolescent girls show high rates of both underweight and obesity, which may lead to the development of NCDs in their offspring. Therefore, the problem of NCDs is no longer limited to adults, but is also prevalent among children. In addition, early intervention offers cost-effective opportunities for preventing NCDs. Thus, children need primary consideration, adequate monitoring, diagnosis, and treatment to reduce the burden of NCDs later in adulthood.

This study was carried out for the prevalence of metabolic syndrome in obese middle school students. The subjects were 104 obese adolescents of 4 middle schools in Namwon city, Jeonbuk. Average age of the subjects was 12.2 years old, BMI of mild obesity group, moderate obesity group and severe obesity group were 24.6kg/m2, 27.5kg/m2, and 31.8 kg/m2, respectively. Prevalence of metabolic syndrome in obese students was 2.9%. And the person who has more than 2 out of 5 symptoms was 22.1%, and more than 1 was 39.4%. The prevalence of each symptoms were abdomen obesity(46.2%), hyper triglyceride(23.1%), high blood pressure(20.2%), high HDLcholesterol(2.9%), but the hyper glycemia had not been found. Nutrient intakes of 3 groups were not significantly different, energy was 1817.9kcal, carbohydrate was 265.7g, protein was 72.2g, and fat was 51.9g. Nutrient adequacy ratio(NAR) of protein, phosphorus, iron, vitamin A, vitamin B1, vitamin B1, niacin, vitamin C was proper, except calcium. Seventy point two percent of the obese students knew 'obesity is a disease', and 49.0% of the subjects didn't know the complication of the obesity. Only 27.9% of the obese adolescents took nutrition education class, but 51.9% of them thought nutrition education was necessary. We suggest that the nation enforce the policy for early detection and treatment of obesity for adolescents. Obese students and their parents should take nutrition education.
