Purpose: The purposes of this study were(a) to identify smoking behavior by following a cohort representative of the population of 4th grade elementary schoolers in South Korea over a four-year period(2004-2007), and(b) to explore predictors of smoking initiation among non-smokers in Wave 1. Methods: Secondary data, the Korea Youth Panel Study, was analyzed in this study. First, frequencies or percentages were calculated to identify smoking behavior(i.e., smoking initiation, smoking intensity, and smoking duration). Second, binary logistic regression analysis was performed to examine significant factors related to smoking initiation. Results: Smoking initiation and daily smoking were more pronounced when the participants entered middle school. In bivariate analysis, statistically significant predictors of smoking initiation were loneliness at school, self-control, delinquent behavior, depressive symptoms, and stress. However, after controlling for other factors, only a high level of risk-taking tendency and a greater number of delinquent behaviors remained statistically significant. Conclusion: Based on greater involvement in smoking among first-year middle schoolers, smoking prevention strategies should be provided to elementary schoolers rather than middle schoolers. A risk-taking tendency and delinquent behaviors should be considered as proxy measures to detect the high-risk group for smoking initiation.

The purpose of this study is to analyze the conspicuous consumption propensity of middle schoolers and to develop effective consumer education programs which help improve consumer socialization. Empirical data were collected by using a questionnaire for 500 middle schoolers who reside in the city of Daegu. The results of this study are as follows: First, significant differences in materialistic propensity can be found. It results from the difference in parents' educational background, amount of monthly pocket money, influence of mass media and friends, and the consumer education hosted by schools. Second, significant differences in the conspicuous consumption propensity can be found. It comes from the difference in materialistic propensity and control of purchasing behaviors. Third, the variables affecting the middle schoolers' propensity of conspicuous consumption include influence of mass media and friends, control of purchasing behaviors, influence of materialistic propensity, amount of monthly pocket money, and mother's educational background. Lastly, this study helps develop consumer education programs for the teenagers. The program should use statistics data, Internet, presentation materials, putting higher priority on experience activities, survey, analysis, discussion, and presentation rather than theoretical education.

This study investigated how elementary schoolers (n=159, 9~11 years) and middle schoolers (n=176, 13~15 years) perceived maternal parenting style dimensions, both general and child-feeding related, and whether these dimensions are associated with the subject's food behaviors. The exploratory factor analysis resulted in a solution of 10 parenting dimensions (reasonable guidance, affection and involvement, achievement expectation, clear behavioral regulation, criticism and anger, overprotection, psychological punishment, harsh punishment, punish by withdrawal of child's privileges, and lack of punishment) and 8 child-feeding dimensions (portion control, restriction, pressure to eat, monitor, undesirable model, desirable model, discourage unhealthful eating, and encourage healthful eating) with 49 and 43 items, respectively. Three parenting styles, authoritarian, permissive, and authoritative, were extracted via a second factor analysis using the 10 parenting dimensions. The correlation analysis indicated that authoritarian style was positively correlated with 'restriction' and 'undesirable model', while permissive style was negatively correlated with 'encourage healthful eating' in both groups. Authoritative style was strongly associated with all of the child-feeding dimensions except for 'undesirable model'. For food behaviors, the more likely elementary schoolers and middle schoolers perceived their mothers as authoritarian and permissive, respectively, the more unhealthful foods were consumed. The consumption frequency of healthful foods increased as mothers were perceived to be authoritative. More elementary schoolers of authoritative mothers ate meals with parents. Findings suggest that maternal parenting styles and dimensions, child-feeding dimensions, and child's food behaviors are associated. It may be that authoritarian and permissive styles are more detrimental for elementary schoolers and middle schoolers, respectively, whereas authoritative style is beneficial for both groups in terms of subject's food behaviors.

Objectives: It is known that the majority of middle schoolers spend the substantial amount of time using the Internet. Despite the fact, little is known about which factors are related to an increase in Internet use and what could be the consequences of excessive Internet use. The aim of this study was to explore factors affecting an increase in Internet use among elementary schoolers representing the population of South Korean elementary schoolers. Method: Secondary data obtained from the Korea Youth Panel Survey were analyzed longitudinally. Results: The average minutes spent using the Internet was 73.43 in the first wave, and was 92.17 in the second wave. Also, the percentage of those who experienced illegal behaviors on the Internet was 22.86% in the first wave, and was 30.92% in the second wave. Second, increased Internet use was strongly associated with an attack tendency, depression, suicidal ideation, stress, and delinquent behaviors. Finally, gender(being female), and increased attacking tendency, and smoking experiences successfully predicted an increase in Internet use one year later. Conclusions: It is necessary to provide education programs to young people and to develop preventive strategies for them. Through providing education programs, children can form desirable attitudes regarding the Internet use. Through providing intervention strategies, children can prevent from experiencing negative consequences due to excessive Internet use.

The goal of this research was to investigate the effect the computer game-based learning has on learning achievement in computer education for middle school students. To achieve this goal 74 middle schoolers were allocated into the experiment group(34 students) with the educational computer games class and the control group(34 students) with the traditional face-to-face class. After identifying the homogeneity of two groups through the pre-test, the experiment was carried out. As a result, the mean difference between the experiment group and the control group was statistically significant. That is, learning achievement of middle schoolers utilizing the computer games was higher than that of the face-to-face class. It is suggested that the game factors should be considered in designing the computer education.

This study attempts to analyze the mechanism of the academic engagement of middle schoolers participating in family education in Technology and Home Economics Education (T&HEE), their resilience, and their parent-child relationships. The purpose of this study is to examine the mediating effect of resilience on the association between academic engagement and the parent-child relationship. The participants of the study were 194 middle schoolers in Sejong-si. The data were analyzed using PROCESS macro (Model 4), a method for verifying the mediating effect using bootstrapping. As a result of the study, first, there are significant positive correlations among academic engagement, resilience, and the parent-child relationship. Second, the result shows resilience as a complete mediating effect on the association between academic engagement and the parent-child relationship. These findings suggest the way to improve the relationship of adolescents with their parents is to enhance the middle school learners' resilience by actively participating in family education classes in T&HEE.

The aim of this study was to evaluate the body composition difference and obesity prevalence in grade 5 to 8 by gender. A total of 1,333 students, 707 boys and 631 girls, were recruited from one elementary and one middle school in Seoul, Korea. Anthropometric measurements including height, weight, lean body mass, and body fat were assessed. Height and weight were increased by grade, but Body Mass Index (BMI) by grade showed no significant difference among boys. Lean body mass had growth spurt between 7 and 8 grade among boys compared to gradual increase among girls. Overweight and obesity prevalence were higher among elementary schoolers than middle schoolers. Overweight (BMI for age> $85^{th}$ percentile) prevalence was about $44\%$ among $5^{th}$ grade boys compared $29\%$ among same grade girls. These results provided that there were prominent difference regarding body growth and obesity prevalence in gender and grade. Further studies for children and adolescents should be considered their body composition change.

The purpose of this study was to delve into how to provide better and more oral health education to middle school students, and to boost school oral health projects. The subjects in this study were 430 middle schoolers. After their oral health awareness, knowledge and oral health care were investigated, the following findings were given: 1. Concerning concern for oral health, 56.7 percent were oral health conscious, and as many as 43.2 percent were little or never concerned about it. 2. As to subjective oral health status, 36.7 percent found their own oral health status to be good, and 63.3 percent had a periodontal disease or felt that there was something wrong with their oral health. Regarding self-assessed abnormal oral symptoms, 25.8 percent considered themselves to have an abnormal symptom related to temporomandibular joint, and approximately 30 percent thought there was something wrong with their gums. 3. As for toothbrushing habits, the number of the girls who brushed their teeth after lunch was statistically significantly far larger than that of the boys who did. There were some differences between the boys and girls in toothbrushing method and in which part of the oral cavity they brushed. 4. In regard to oral health knowledge, the girls(a mean of 7.05) significantly excelled the boys(6.36). Those who were more oral health conscious got significantly better scores in oral health knowledge. 5. In terms of dental-clinic visit experiences, the students who had ever visited a dental clinic took in less sugar and got a more frequent regular dental checkup(2.62, 2.50) than the others who hadn't(2.32, 1.74).

This research attempts to analyze the physical characteristics of middle school girls and compare the product sizes and patterns of school uniform blouses by brand. And wearing tests were performed regarding the appearance of blouse by bland. The results are follows. The standard deviation for bust circumference and waist circumference of middle school girls measured in 2004 were showed extremely large difference among individuals compared to the previous results. While waist back length reached adult size by $2^{nd}$ grade high school, bishoulder length reached adult size by $2^{nd}$ grade middle school. And girls after $2^{nd}$ grade middle school had their depth and breadth of bust, underbust circumference and bust circumference growing proportionally. These results need to be reflected in producing a pattern drafting for middle schoolers. By comparing wearing test results on appearance, it was shown that in terms of ease of bust circumference, the expert group evaluated brand with less ease as not having adequate ease compared to brand, while the middle schooler group evaluated as having sufficient ease. The front silhouette also showed same results. This reflects the preference for appearance by the middle schooler group, which is a factor to be considered during pattern drafting of school uniform blouse.
