This study investigated the current tendency of the middle school student's use of the food and nutrition information from the internet web site. The research employed web survey for the national middle school students. Middle school students usually searched the internet information to do homework and to solve the own curiosity. Forty percent of respondents had experience to get food and nutrition information from tile internet, and 74% of them were girl. Cooking method and world cooking exploring were the most wanted information among food and nutrition information. Professional cooking site and tips of food and nutrition from study aiding sites and monthly magazine sites were tile resources of food and nutrition information. The mai or reasons for searching the food and nutrition information were to know the cooking method and out of curiosity. The most unsatisfied problems were unnecessary information, too much advertisement and too difficult contents when the users approached the site to get the food and nutrition information. Students who have been not interested in and had no homework about food and nutrition, had no visiting experience of web sites for food and nutrition information. Therefore, to provide food and nutrition information for teenagers through internet, web sites were developed to have easy contents linked to study aiding site or other sites that teenagers frequently visit. Since teenager's interest about health issues is not as high as adult's one, the contents of sites must be easy for teenagers to follow and fun, however, should be based on scientific facts on food, nutrition and disease.

This study targeting 10 high school 3rd grade students who have studied space figures in natural sciences track analyzes the process of analogical discovery from the construction of inscribed and circumscribed circles of a triangle to that of inscribed and circumscribed spheres of a tetrahedron through the analytical method using Geogebra. The subjects are divided into two groups of five, the experimental group consisting of those who have experienced analytical method and the comparative group consisting of those who haven't. This research analyzing the process of constructing inscribed and circumscribed spheres of a tetrahedron. Although students of both groups all have an accurate preliminary knowledge of inscribed and circumscribed circles of a triangle, they have difficulty in constructing inscribed and circumscribed spheres of a tetrahedron. However, the students of experimental group who have studied the constructing process of inscribed and circumscribed circles of a triangle in reverse using analytical method and Geogebra can perform analogical discovery finding out the way to construct inscribed and circumscribed spheres of a tetrahedron using analogy by themselves. They can control and explore space figures by visualization. Also, they can immediately examine and provide feedback on the analogizing process of their own. In addition, the process affects the attitude of students toward mathematics positively as well as gives validity to the result of analogy.

Purpose: The purpose of this study was to determine the relation between test anxiety and mental health in adolescents. Method: The subjects were 450 students of two academic high schools in J City, who were selected through convenient sampling. Data were collected through a survey using a structured questionnaire from September 1st to 15th 2005. Collected data were analyzed using SPSS 10.0 for Windows through descriptive analysis, Pearson's Correlation Coefficient, t-test, ANOVA, Scheffe's test and stepwise multiple regression. Result: The mean score of test anxiety was 2.40 (range:1.13-3.81) and that of mental health was 2.77 (range:0.64-5.03). A significant negative correlation was observed between test anxiety and mental health (r=-0.28, p=.000). Test anxiety was significantly different according to adolescents' general characters such as gender (t=-1.98, p=.048), grade (F=3.54, p=.030), school life satisfaction (F=10.73, p=.000) and relationship with the teacher (F=11.60, p=.000). Mental health was significantly different according to adolescents' general characters such as religion (t=2.14, p=.032) and school life satisfaction (F=4.13, p=.017). The most powerful predictor of mental health was test anxiety and it, combined with religion, accounted for 9.0% of variance in mental health in adolescents. Conclusion: Test anxiety and mental health was found to be in a significant negative correlation with each other in adolescents. Therefore, nursing intervention programs for adolescents needs to reduce their test anxiety to improve their mental health.

The current geometric and vector textbooks focus on the mechanical activities of finding focus, corner, etc. through elliptic equations. In this paper, we propose a process in which analogy and analytical methods are used in reversible activities of focusing from a given elliptic graph without a coordinate plane. The exploratory tool was used as Geogebra. At first, students tried to find the focus of the ellipse by randomly constructing the major a is and the minor a is in the given ellipse. However, we have experienced a method of constructing the circle of symmetry and analyzed this principle and deduced it to the ellipse. As a result, we could construct the center, long a is and short a is of the ellipse. Then, using the analytical method, the focus formula was recognized as the Pythagorean theorem, and the ellipse's focus was constructed by using the original drawing. Therefore, it is confirmed that analogy and analytical method can positively affect the elliptical focus.

Sample subjects were the 3rd grade of high school in Chungnam Province and the number were 1,014. The data had been collected on Dec. 3th-8th, 1990 according to the tool of Institute on Drug Abuse of Korea. And then Frequency and $x^2-test$ were need to analyse of data by SPSS-X program. The results of this study could be summarized as follows. 1. They had used 14 kinds of drugs: $70.1\%$ of the subjects students used alcohol, $69.2\%$ analgesics, $38.6\%$ cigarette, $15.0\%$ stimulants, $14.7\%$ antitussives, $11.2\%$ antithistamines, $8.9\%$ hypnotics, $7.1\%$tranquilizers, $4.2\%$ inhalants, $2.3\%$ marijuana, $1.4\%$ hallucinogens, $0.9\%$ cocaine, $0.6\%$ amphetamines, and $0.6\%$narcotics. The boys' drug using rate is higher than girls' except in analgesics and stimulants. 2. With respect to misbehaving, $43.0\%$ of the students said they had pop houses, $42.4\%$ adult video, $17.4\%$ unexcused absence from school, $11.0\%$ dangerous weapon, $9.1\%$ sexual intercourse, $70.1\%$ disappearance from home, 8.0% blackmail, and $6.0\%$ assault. In every kinds of misbehaving, the boys' misbehaving rate is higher than the girls'. 3. Almost every kinds of drugs have the students first used at the age of 15 through. 18. And $13.8\%$ of the students smoked every da·y and $1.7\%$ drank every day. 4. The frequency of the drug using such as cigarette (p<.01), marijuana (p<.05), cocaine (p<.05) and narcotics (p<.05) showed the stastically significant differences according to the religions of the subjects 5. The subjects who has complaints about someone use more drugs than the ones who doesn't, and who doesn't have any complaints about five elements have never used drugs such as marijuana, cocaine, amphetamines, narcotics, hallucinogens, and inhalants. 6. The drug using subjects have the more experiences of adult video, pop houses, and unexcused absent from school than the non-drug using ones. It means that the subjects who use drug were apt to do misbehaving more often than the ones who have never used them, and delinquent boys and girls use more drugs.

This study was focused on the relationships between menstrual history and psychological variables in middle school girls. The study included 165 students. Self image, optimism and self-efficacy are measured structured questionnaires each. Statistical analysis was performed using t-test, ANOVA and Scheffe's test. The proportion of the students with bleeding period less than 7 days was higher in the group with high self image(p=.002). The self image was higher in the group who take analgesics occasionally than the group who take daily(p=.009) and in the group with irregular menstruation(p=.024). Emotional tone was higher in the group with irregular menstruation(p=.008), and psychopathology was higher in the group who take analgesics occasionally(p=.008). Family relationship was higher in the group with bleeding period less than 7 days(p=.004), in the group who take analgesics occasionally(p=.007) and in the group with irregular menstruation(p=.015). Mastery and coping was higher in the group with bleeding period less than 7 days(p=.026). Adaptation was higher in the group with irregular menstruation(p=.034). Also optimism was higher in the group with bleeding period less than 7 days(p=.005), in the group who experienced menorrhalgia a few years after menarche(p=.014) and the group with irregular menstruation(p=.027). Self-efficacy was higher in the group of polymenorrhea(p=.029). Because menstruation is related with psychiatric factors, it is necessary to ask menstruation history and psychiatric status. This study can be used in the development of the questionnaire for the oriental medical examination.

The purposes of this study were to develop a program utilizing learning strategies for underachieving middle school students in science and to identify the effectiveness of the program on the ability of using learning strategies and the improvement of science academic achievement. For this study, we developed the program of learning strategies consisting of eleven consecutive lesson plans focusing on the content of 2009 revised national science curriculum and applied the program to three underachieving students in science of 7th grade, who have weaker learning strategies that can be used for science study than other underachievers. After treatments, we analyzed the effectiveness of this program through science learning strategy tests, overall assessments, student-activity sheets, research logs, learning-transcription details, analysis of interviews with students, and observation of classes. According to this study, the enhancement of the ability of using learning strategies was limited because it was difficult for the students to change their fossilized strategies. On the other hand, their overall academic performance was considerably improved since the students became interested in studying science drawing on the learning strategies. Therefore, the program of learning strategies had a positive effect on improving the science underachievers' ability of using learning strategies and academic achievements.
