Purpose: This study investigated the predictors of Sexually Transmitted Infections (STI) among female teenagers in Korea who have had intercourse at least once. Methods: This study is based on the 12th Korea Youth Behavior Web-based Survey conducted in April 2016. Data were collected from 798 middle schools and high schools nationwide in Korea and 65,528 students participated. Among the participants, the subjects of this study were 537 female high school students (Grade 10~12). The data were analyzed through complex samples multiple logistic regression using SPSS statistics 22. Results: Among the 537 female adolescents, 11.9% replied they had experienced STI. The predictors of STI among the subjects were 'age at first intercourse' and 'sexual intercourse after drinking'. The risk of STI was lower in the middle (OR=0.26, 95% CI=0.10~0.64) and high school (OR=0.11, 95% CI=0.04~0.27) age groups than those who had their first sexual intercourse at an elementary school age. The sexual intercourse after drinking group had a higher risk of STI, compared to the no sexual relation after drinking group (OR=2.54, 95% CI=1.28~5.07). Conclusion: Practical sex education programs should begin from the elementary stage in order to protect more female adolescents from STI. In addition, sex education including an alcohol prevention program should be considered to lower STI among female adolescents.

Recently sports injuries are increasing due to the development of sports leisure industries as well as the increase of exercising population, and the study for sports injuries is needed more than before. Then the author studied the reasons for injuries, incidence rate, sites and sorts of sports injuries for the middle and high school football players during one year period from Jan. to Dec. 1994. The study subjects were 319 middle and high school players in Pusan and the method was questionnaire method. The results were as follows; 1. The average injury rate due to football play was 3.3 times per person for the 319 subjects during the last one year, and it was highest in goalkeeper as 4.6 times by position. 2. 68 % of the subjects did not receive periodic health examination, 74.9 % wore body protectors. The sports injuries due to football play occurred most commonly in soil play-ground(79.6 %), during training(52.3 %), and in winter time(33.7 %). 3. The commonly occurred injuries by motion were coalition(39.2 %), tackle(12.9 %), dribble (11.4 %) in order; those by sorts were contusion(34.4 %), sprain (32.9 %), spasm(9.0 %) ; and those by body portions lower extremities(82 %), trunk(17.6 %), upper extremities(12.5 %). 4. The frequently used treatment area was home care as in 42.7 % ; treatment methods were physical therapy, acupuncture/moxacautery, rest, operation in order; choices of treatment method were recommendation by coach/manager, and that by medical professional was the lowest as in 2.2 %. 5. If sports injury occurred during play, coach or manager let the players take rest in 56.2 %, but emergent management by medical professional was done only in 1.9 %. The return to play was decided mostly by the player himself(52.8 %), but that decided by a doctor was only in 1.0 %. In conclusion, to lessen the sports injuries due to football play, annual physical check-up, strengthening of play rules, improvement of playground, conditioning exercise, regulation of body protectors, and preventive training for expected injuries behaviors should be done and the decision to return to play and emergent management should be done by a medical professional as well. Football player, sports injury, injured body portions, sorts of injury, treatment method.

The purpose of this study was to investigate high school students' perceptions on chemistry subjects: reasons for choosing chemistry, learning volume and content difficulty, interests, teaching/learning methods, preferable classes etc. A total of 1,087 students who took chemistry subjects at 126 high schools by proportional stratified sampling were voluntarily participated in the survey. The main reasons the students chose chemistry subjects were interests and interests in chemistry, foundation to science, relevance to college majors, and so on. Students recognized that the learning volume and content difficulty as normal level was about 60%. Reasons why chemistry was difficult was that, although there was a difference in degree, chemistry was difficult in itself and had too much things to memorize. In the case of interests in chemistry subjects, students of 43.9% of Chemistry I and 52.0% of Chemistry II recognized the level as normal. The reason why not interested in chemistry subjects was that it was the nature of chemistry contents, or students had neither interests and enjoyment of chemistry nor foundation for chemistry. Classes were mostly lectures but the students preferred mainly experimental activities, or explanation with real-life examples or science stories. The frequency of experimental activities was found to be 1 to 5 times per semester, or not experimented. Research and efforts will be necessary to improve classes and environments for students' experimental activities.

Objectives : This study was conducted to analyze the stress, coping and physical symptoms relevant to factors influencing physical symptoms on high school girls. Methods : The subjects were 521 high school girls in I city. The data was collected by using structured questionnaire. T-test, ANOVA, Pearson's correlation and Stepwise-multiple regression were performed by SPSS/PC 17.0. Results : Study-related stress were higher in the freshmen than sophomore (p=.001). The sophomore have highest level in family (F=5.32, p=.005), friends (F=3.13, p=.044), and appearance-related stress (F=5.49, p=.004). Poor grades in their studies were related to family-related stress (p=.010) and study-related stress (p=.009), They complained severe discomfort, displeasure, and G-I symptom in order. The more physical symptoms were, the more coping with their stress do (p=.001). Factors affecting physical symptoms are study-related stress (${\beta}$=.38), unhealthy (${\beta}$=.16), friends (${\beta}$=.14), active coping with stress (${\beta}$=.15) and sophomore (${\beta}$=.11), family (${\beta}$=.11), and they explained 33.3% of variables. Conclusions : Students have to learn how to cope with their stress. Therefore, it is needed program development to improve stress management for high school girls.

We examined the science education system in North Korea from the elementary to the high schools. We also analyzed the physics textbooks used in North Korea and compared the results with the textbooks used in South Korea. We compared the goal and system of physics education, and the content, order of study, and volume of the textbooks. Physics education starts at the 4th year at the elementary school, and is taught through the whole school years in North Korea. The science process skills are regarded to be important and figures, tables, problem sets, experiments, and sample solutions are exclusively used in the textbooks. Electomagnetism occupies the largest portion in physics textbooks, but subjects related to the application of physics are more stressed. There are a few subjects which are included in the North Korean textbooks but not in the South Korean textbooks. We have compiled about 60 North Korean physics words which are different from the South Korean words used in the textbooks. Overall, there will be not much difficulty in integrating the physics education system and physics textbooks after the two Koreas are unified.

This study was to find science high school students' perception about composing laboratory reports by grade. The instrument to survey the perception of them consisted of the perception about making a lab report, and the effect of compositing laboratory reports on the scientific concept understanding and the scientific inquiry ability. Subjects were 260 students of four science high schools in Seoul metropolitan city and Kyounggi province. Most of science high school students had a little positive perception about compositing lab reports, but they had very positive perception about the effects of it on the scientific concept understanding and scientific inquiry ability. There was the significant difference between grades, because the 10th grade students showed more positive perception toward compositing lab reports than the 11th graders(p<.05). The results suggested that different educational approaches and teaching strategies be needed for science high school students considering grades.

We seek the possibility of introduction of Fractals to the high school math. curriculum through identifying Fractals teaching programs appropriate for the scopes and sequences in math. education for the high school students. We presented the contents of Fractal theory suitable for the high school students. The following subjects were chosen to be introduced; self-similarity, Fractal dimension, Cantor set, Sierpinsky triangle, Sierpinsky carpel Koch curve, Koch island, perimeter estimate of rugged profiles drawn on paper, and chaos game. We developed the working papers and the criteria for appraisal. Each working paper focuses on the activities in which students can solve the given problems, understanding the characteristics and ideas of Fractals. The working papers were given to the second year students who take science course, and the degree of achievements were analyzed based on the appraisal criteria. The results show that it is possible to introduce Fractals to the high school students.

The purpose of this study was to study the degree of consciousness and satisfaction of body cathexis of high school girls' lower bodyshape. The subjects in this study were 296 high school girls. The results were as follows : 1. The degree of satisfactions of girth items in lower part of the body were influenced by real body size than ideal body size. But the degree of satisfaction of weight was influenced by ideal body size and height was influenced by real size body. 2. The high school girls thought ideal body shape was tall in height, long in leg, slim in girth and light in weight. Therefore, they wanted to have slimmer, longer, and lighter body size than real body size. 3. The high school girls were more satisfied with lean body type than with standard body type or with obesity body type. Therefore they wanted to be lean body type.

Objectives: The purpose of this study is to investigate the influencing factors on oral health related self-efficacy and social support in high school students. Methods: The subjects were 750 high school students in Jeonbuk by convenience sampling. A self-reported questionnaire was completed from April 3 to June 4, 2013. Except incomplete answers, 589 data were analyzed using SPSS 18.0 program for t-test, ANOVA, post hoc Scheffe test, and multiple regression analysis. The questionnaire consisted 6 questions of general characteristics of the subjects, 8 questions of oral health related self-efficacy, and 8 questions of oral health related social support. The instrument for self-efficacy was developed by Sherer and Maddux and measured by Likert 4 scale. Interpersonal Support Evaluation List(ISEL) was developed by Cohen and Hoberman and revised by Suh as oral health related social support in high school students, and measured by Liker 4 scale. Cronbach's alpha in self-efficacy was 0.768 and that in social support was 0.772. Results: The good oral health behavior in the high school students was closely related ro self-efficacy and social support. Higher self-efficacy and social support could make the students practice good oral behavior. Conclusions: Higher self-efficacy and social support can influence on the good oral health behavior in high school students. So it is very important to provide the continuous oral health education that can enhance self-efficacy and health promotion.

This study investigated the food and dietary educational content in primary, middle and high school textbooks in order to provide fundamental data for the development of educational programs on Korean traditional food culture. The research objects consisted of 51 kinds of textbooks (15 kinds of primary school textbooks, 29 kinds of middle school home economics textbooks and 7 kinds of high school home economics textbooks), and the contents related to food and dietary education were counted and analyzed. The content analysis was performed using two categories: application method and subject matter. Application method included texts, cases, visual aids (pictures, photos, illustrations, chart, etc.) and activities, whereas subject matter consisted of seven types (well balanced nutrition and health, understanding of food and nutrition, cooking principles, cooking lessons, traditional foods and culture, others). The results of the application method in primary school textbooks show that visual aids were the most common in all six grades. For the subject matter, 'understanding of food and nutrition' was most abundant in primary school textbooks while 'well balanced nutrition and health' accounted for a large part of the contents in middle school textbooks. However, the contents regarding traditional foods and culture were insufficient in primary and middle school textbooks. These results suggest that educational contents on traditional foods and culture should be added to primary and middle school textbooks and covered in various subjects. Furthermore, high school 'home economics' contents need to emphasize comprehensive food and dietary education and adjust to 'science & technology for life'.
