Recently, Korean high school students eagerly utilize the educational contents via personal computers and ubiquitous equipments like PMP. We investigated the utilization status while in high school of one class students of M university located in Daejeon area. About 30% of students used PMP and whole students used personal computer to take educational contents. Almost all of the students paid less than 200,000 won for the contents while in their high school. Most popular sites were EBS and Megastudy.

The present study was conducted to analyze high school students' attitudes toward jean brand counterfeits relative to their self-esteem and self-consciousness. The study was implemented through a normative-descriptive survey using questionnaire. The sample consisted of 605 high school students from 6 high schools located in Seoul. Data were analyzed by mean, cluster analysis, regression, ANOVA and Duncan's test. The results were as follows: (1) As a whole, the mean values of preference and purchasing intentions toward counterfeit jeans were 2.99 and 2.83, respectively, indicating a slightly low average on the 5-point Likert scale. The results indicated that 45.5% of respondents have more than one item of counterfeit jeans. (2) Differences were found in the level of self-esteem and public self-consciousness among the three groups, who were classified by the level of purchasing intention and preference toward counterfeit jeans. Among the three groups (high/middle/low), the group having low purchasing intention and preference toward counterfeit jeans showed higher self-esteem and public self-consciousness than the other two groups. (3)Regression analysis showed that the self-esteem and public self-consciousness of high school students have an impact on the amount of purchasing of counterfeit jeans. (4)In the process of developing effective policies against the jean brand counterfeits market, it should be fully considered that high school students' purchasing intentions regarding jean brand counterfeits are related to their self-consciousness. It could be said that the policies followed to eliminate counterfeits and to enhance the consumer ethics of high school students will be more effective when those policies are accompanied by efforts to form their sound self-consciousness, especially in the areas of self-esteem and public self-consciousness.

Objective: This study was conducted to investigate the relationship between the intention of smoking and its related factors in high school students. Methods: Our study subjects were 1,203 high school students who resided in one city and in one county region. We conducted a self-administered questionnaire survey from June 7 to June 19, 2004. Both the decisional balance and temptation inventory showed high reliability estimates. We provided good fit for the 12-item decisional balance inventory and the 10-item temptation inventory by using a confirmatory factor analysis. We also used multiple logistic regression analysis to identify the major contributing factors for the intention to start smoking. Results: On the univariate analysis, the subjects who were female, the 2nd and 3rd grade students, the students in vocational high school, the ex-drinkers or current drinkers, and ex-smokers were found to be significantly more distributed in the groups with intention to start smoking. Except for the concept of the cons, the group with intention to start smoking showed significantly higher standardized T scores for the 7 concepts of decisional balance and temptations. On the multiple logistic regression analysis, the females, the 2nd and 3rd grade students, the students in vocational high school, the experience of cigarette smoking and low T score of the cons were significantly related to the intention to start smoking. Conclusions: The intention to start smoking in high school students was affected by various factors such as gender, the school grade and the experience of smoking. Therefore, further research should be conducted for providing the essential data for developing a brief instrument for selecting the groups with intention of starting smoking among adolescents.

Purpose: The purpose of this study was to investigate the features and the control factors of headache among high school students. Methods: Data were collected from 120 high school students who suffered headache over one time per a year. The gathered data were analysed with frequency, t-test, ANOVA and $X^2$-test using SPSS 14.0 Program. Results: There were no significant differences in the frequency and the intensity of headache according to general characteristics except status of family economy and the perceived satisfaction of schoolwork achievement and no significant difference were observed in the features and the control factors according to the gender. The main cause of headache of the high school students were stress and the lack of sleep. Conclusion: These results suggest the need to develop a program that would help students relieve schoolwork stress which would help preventing the major cause of headaches for high school students.

The purpose of this study was to find the effect of molecular movement model based instruction on high school students' conceptions of diffusion and osmosis. The study was composed of two groups, the traditional instruction group in which the so-called traditional instruction was performed, and the other group in which interventions by researchers were made. The subjects of the traditional instruction group consisted of a total of 242 high school students from Seoul, Gwangju and Mokpo. The subjects of the model based instruction group consisted of 177 first-year high school students in Mokpo. The study was focused on the use of the term of 'molecular movement' in their explanation of diffusion and osmosis in the correct contexts. In general, students who got the molecular movement model based instruction showed more frequent use of the terms of 'molecular movement' in the correct contexts than the control group students did. It was found that misconceptions including teleological explanations changed into scientific explanations by the intervention. It seemed that the molecular movement model led students to make scientific explanations on natural phenomena. A further research is recommended to assess the improvement of teleological explanation and scientific attitude by the molecular movement model.

Purpose: This study was done to determine the effects of a neurofeedback program on brain function and stress in occupational high school students. Method: A nonequivalent control group, non-synchronized with pre-posttest design was used with 62 students. Data collection was done from July to December, 2007. The neurofeedback training was given for 30 minutes at a time, three times a week for 12 weeks. Brain function was measured by brain waves in the frontal lobes of the students and analyzed by eight brain quotients characterizing patterns of EEG rhythms. The instrument used to measure stress was a scale for stress from regular daily life. Results: After neurofeedback training, the level of brain quotients in students in the experiment group increased(t=2.36, p<.05) and the level of stress decreased(t=-3.59, p<.001). Conclusion: The results of the study suggested that a neurofeedback program is effective for brain function improvement and stress reduction in high school students. Therefore, the conclusion of this study is that neurofeedback programs can be useful to increase brain function and decrease stress in occupational high school students.

This study was conducted via survey of 300 enrolled male and female high school students in the Chungnam area. The survey focused on students' dietary habits, changes in dietary habits based on the school lunch menu, and satisfaction of school lunches, in order to identify new methods for changing dietary habits and improving satisfaction of school lunches. Regarding the general characteristics of those surveyed, most were 17 years old, and of the same gender. Ninety-nine percent of those surveyed lived in farming areas, and the majority of students' parents graduated from high school and are self-employed. Research on dietary habits according to gender found that male students ate more regularly than did female students, with a difference of (p<0.001) between the two genders. Regarding the degree of which students ate only what they want, differences of (p<0.05) were found between the genders. The types of snacks frequently consumed were found to be flour-based snacks for the male students, whereas the females mostly consumed sweet foods and bread snacks. Research on satisfaction of school lunches according to gender also showed a difference of (p<0.5). Specifically, 48.7% of male students responded 'average', whereas only 45.3% of female students responded in the same way. The reason for dissatisfaction of school lunches were quality and nutrition for the male students (30%) and taste for the female students (60.4%), with a significant difference according to gender (p<0.05). Regarding the types of food most left over, both female and male students answered fish, bean curd, and soy products.

The purpose of this paper is to identify the conceptions of middle school and high school students about visible light, Ultra violet(UV) and Infrared ray(IR). We administered questionnaire 40 people of middle school 3rd students and 43 people of high school 2nd students in Gyeonggi-do. Misconceptions about visible light, UV and Ir were observed in many students. The results of study are as follows: Firstly, Many students think that it is possible to see objects without visible light. The explanations given by students for the visiblity of objects in darkness indicates a heavy reliance on personal experiences. Secondly, we have confirmed that high school students well understand the fact that the object reflects the light. However, a significant number of students exhibited an eye-centered perspective of vision. Thirdly, students had a variety of ideas about the meaning of the term UV and IR. Analysis of questionnaire data indicates that many students believe that it is possible to see objects in the presence of UV light alone.

The purpose of this study was to examine the differences of Psycho-social environments by the variables of sex and type of school. Subjects in this study were consisted of 1.011 adolescents drawn from 11 high schools in Cheongiu city and Choeongwon gun. For data analysis. t-test and three-way ANOVA were conducted by SPSSWIN program. This results were as following: Boys' high school students who having romantic partners had lower school adjustment and behavioral adjustment than those without romantic partners. Girls' high school students who having romantic Partners had lower peer relationships and behavioral adjustment than those without romantic partners. Also. regardless of school types. students with romantic Partners had lower school adjustment and behavioral adjustment than those without romantic partners. In an academic high school. students with romantic Partners had negative family relationships. whereas in commercial high school. students with romantic partners had Peer relationships more negatively than those without romantic Partners. This results suggest that adolescents' romantic partners be important factor of social-Psychological development. Especially. romantic partnership would be critical to induce problem behavior such as maladjustment and negative relationships in the environments of family and school.
