Purpose: In an attempt to measure the changes in gender-egalitarianism after sexuality education based on the gender-egalitarianism in middle school students, this study was carried out. Methods: The subjects were 137 students (67 boys and 70 girls) in 4 classes that were randomized from among 8 classes of first graders in a coeducational middle school, in Seoul. By the school nurse with the assistance of an advisory committee on sex education by the MOE, sexuality education was implemented based on gender-egalitarianism. The content was presented over 18 hours during 16 weeks, from September, 2001 to December, 2001. For the pre and post check on gender-egalitarianism, a Gender Egalitarianism Scale modified by the researcher was used. Results: After the sexuality education based on the gender-egalitarianism, there was a significant elevation in gender-egalitarianism(t=4.378, p=0.000). There were no significant differences in the mean changes in gender-egalitarianism according to religion, economy level, educational level of parents, and openness of parents. And little experiences in adult video, no experience in masturbation, and being without the opposite sex were related to significant elevations in gender-egalitarianism. The case of the having the positive sexual attitudes showed a significant elevation in gender-egalitarianism as compared with the case of having negative sexual attitudes. Conclusions: Based on these results, sexuality education based on gender-egalitarianism for youth was effective in elevating gender-egalitarianism scores. Because the case of the wide experiences with sexual behaviors showed a tendency to make low gender-egalitarianism, the education program would be effective to implement early in the school as childhood is a period in which children have a non-established sex-role.

This study aims to understand the relationship between the practice of physical activity guideline for adolescents presented by government agencies and smartphone problem experience. To that end, the association between the practice of physical activity guideline and smartphone variables was analyzed by utilizing 62,225 data from "2017 Youth Health Behavior Survey" and multiple regression analysis was conducted using the SPSS 23.0 program. The analysis showed that all physical activity variables, except for "physical activity for more than 60 minutes," have negative effects on the smartphone problem experience. In addition, students who practice physical activity guideline presented by government agencies, such as aerobic exercise, muscular exercise, participation in sports clubs, and sedentary behavior, experienced less smartphone problem compared to those who did not practice, which showed significant differences in gender. According to the results of this study, it is thought that academic in-depth research using this guideline and differentiated physical activity promotion programs by gender will be possible in order to prevent smartphone addiction.

Objectives: This study was conducted to identify the characteristics of health behavior and self-esteem and the relationship between the two factors among elementary school students with multi-cultural family background. Participants: Survey participants were 87 multi-cultural family children who lived in Seoul and Kyoungi areas and were registered in the local elementary schools. Methods: Data collection was conducted by face-to-face interview survey. Elementary education majored undergraduate students who participated in the education support program for multi-cultural family children in the Ministry of Education and Science and primary researcher of this study interviewed the target students and finished the survey questionnaire based on the students' responses. Survey included general characteristics, multi-cultural family characteristics, self-esteem, and (physical, mental, and social) health behavior. Results: 1. The self-esteem scores of the multi-cultural families children were greater in girl than boys among the children whose parents were graduated from college or more, and whose father had his job. The participants' health behavior scores were different by mothers' educational level. 2. The better they speak in English the greater the self-esteem scores. There was no statistical difference in health behavior scores by the participants' multi-cultural family background. 3. Self-esteem had moderate level correlation with health behavior (r= .56, p= .00) including all sub-categories of physical, mental, and social health. Conclusions: Positive self-esteem level is more sensitive to explain multi-cultural family children's health behaviors, which means that self-esteem is an important factor determining multi-cultural children's health behaviors and their health status in future. Therefore, more research to identify the factors related to health behaviors should be supported and the health promotion programs utilizing self-esteem should be developed for the child and youth with multi-cultural family backgrounds.

There is a lack of data on metabolic risk factors during pre-puberty, which is important for identifying the subgroups of youth, at whom early interventions should be targeted. In this study, we evaluated the prevalence of metabolic risk factors and its subsequent relations with dietary patterns in Korean pre-pubertal children through a cross-sectional sample (n = 1,008; boys = 513) of pre-pubertal children (aged 8-9 years) from a sub-study of the Korea Metabolic Syndrome Research Initiatives (KMSRI) in Seoul, Korea. Measures of anthropometry and blood pressure as well as fasting blood samples were used in the analysis. A three-day food records were collected. The metabolic syndrome was defined according to the age-adjusted National Cholesterol Education Program Adult Treatment Panel III guidelines. An added metabolic risk score was calculated for each subject by summing the quintile values of the five individual risk factors. Among the 5 risk components of metabolic syndrome, high waist circumference (WC) was the major factor (P < 0.001). A significant increasing trend of the added metabolic syndrome risk score was observed with the increase of WC (P (trend) < 0.001) among both genders. The cutoff point for high WC for pre-pubertal children was 61.3 cm for boys and 59.9 cm for girls. The prevalence of high triglyceride (TG) values was significantly higher in girls than it was in boys (P < 0.01). Girls in the highest quintile of balanced dietary pattern scores had lower TG values (P (trend) = 0.032) than did those in the lowest quintile. Moreover, girls in the highest quintile of western dietary pattern scores showed increasing trend for the added metabolic risk score (P (trend) = 0.026) compared with those in the lowest quintile. Adverse associations exist between western dietary patterns and the accumulation of metabolic risks among girls, not in boys, even during pre-puberty.

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.

Korea, China and Japan show distinct features in their school environmental education, which are derived from their own spreading processes. Japanese school environmental education has developed as a result of assimilating of anti-pollution education and nature education, and has a feature that makes much of nature experiences. The introduction of 'Period for Integrated Study' in 2002 seems to begin activating Japanese school environmental education. Chinese school environmental education started in higher education institutions around the middle of 1970's, and has a feature that makes a point of scientific approach, even in primary education schools. The two government ordinances,'National Action Program for Environmental General Knowledge ($1996{\sim}2010$)' and 'Educational Scheme of Environmental Theme Study for Elementary and Secondary School Students' issued in 2003, gradually promote school environmental education in China. It is remarkable that Science and Technology Centers for Youth and also increasing environmental NPOs often support environmental activities in elementary or secondary schools. The most notable feature of Korean school environmental education is that 'Environment' has already offered as a regular elective subject in junior high school, and official 'Environment' textbook has published since early 1990's. Though, the adoption rate of 'Environment' is not yet so high. Each country's peculiar issues are as follows. Japan: (1) Students often lack basic knowledge about environmental important problems. (2) 'Period for Integrated Study' is now threatened with cutting hours by the idea of increasing periods for basic subjects to keep high achievement. China: (1) There are large regional differences and school distinctions in operation of environmental education. (2) Adult environmental education needs to be expanded, because the most part of Chinese have no experience of school environmental education. Korea: (1) The relationship between the administrative division which plans school environmental education and teachers group is not quite well. The adoption rate of 'Environment' in junior high school needs to be improved. The training of many teachers for environmental education instructors may be the most important and effective cooperative action among Korea, China and Japan, and for that purpose we ought to work on making a better handbook for instructors, at first.
