To analyze the dietary behavior and food preference of Korean youth, we surveyed 140 elementary school 6th grade students and 154 high school first grade students in Youngnam Provinces. The average height and weight for the elementary school students were 153cm and 45.3kg for boys and 153.4cm and 44.6kg for girls. The body types depending on the body mass index(BMI) were 45.7% for under-weight, 47.1% for standard, 3.6% for overweight and 3.6% for obesity. The average height and weight for the high school students were 172.5cm and 64.5kg for boys and 160.1cm and 51.7kg for girls. The body types depending on the BMI were 11.0% for under-weight, 70.8% for standard, 13.0% for overweight and 5.2% for obesity. In their food preference, they preferred one-dish food to main dishes and rice with cereals was more popular among high school students. There were higher standard scores in fruit, snack, fried, and Kimchi dishes and high school students showed a high preference especially for snack and fried foods. The Kimchi dishes were more popular among elementary school students and they showed high scores in those dishes regardless of how they were cooked. There was the lowest preference for Korean vegetable salad and the highest for food cooked with meat In conclusion, a difference was found in the food preference of elementary school and high school students and the nutrient intake of elementary school students was lower than that of high school students. Therefore, elementary schools should provide proper nutritional education for students.

The purposes of this study were to investigate the intercorrelations among various motivational patterns and learning strategies and to examine the differences in motivation and strategy usage in terms of students' science achievement level, gender, and grade. A questionnaire on achievement goal, self-efficacy, self-concept of ability, expectancy, value, causal attributions, and learning strategies was administered to 360 junior high/high school students (178 males, 182 females). Students who adopted performance-oriented goal tended not to be task oriented. Task-oriented students had high levels of self-efficacy, high self-concept of ability, and expectancies for future performance in science. They also valued science and attributed thier failures to the lack of effort. However, performance-oriented students evaluated their ability negatively, did not value science, and attributed thier failures to uncontrollable causes. With respect to learning strategy, task-oriented students tended to use deep-level strategy, whereas performance-oriented students tended to use surface-level strategy and not to use deep-level strategy. High-achieving students, boys, and junior high school students were more task-oriented, evaluated their ability more positively, and valued science more than low-achieving students, girls, and high school students, respectively. High-achieving students and boys also used deep-level strategy more than each of their counterparts. However, no significant difference in learning strategy was found between junior high school students and high school students. Educational implications of these findings are discussed.

Purpose: The purpose of this study was to investigate relationships between short sleep, obesity, and screen time. Methods: Data were obtained from a survey using a sample of 1,166 academic, and 597 vocational high school students. A structured questionnaire was used to assess demographics, hours spent in sleep, TV viewing, internet usage, and game playing. Obesity was determined using the body mass index. Descriptive statistics, Cochran Mantel Haenszel Chi-square test, and multiple logistic regression with dummy variables were performed. Results: Short sleep (<8 hours/day) was significantly related to obesity, not in academic school students, but in vocational school students. Academic high school students who had enough sleep (${\geq}8$ hours/day), had more time spent on TV viewing, internet usage, and game playing. Similar results were found in vocational high school students except for internet use. Interestingly, students with better school performance spent significantly less time in TV viewing, internet usage, and game playing, and therefore had a lower risk of obesity in academic school students. Conclusion: There is a significant relationship between short sleep and obesity that was found only in vocational high school students. The relationship between short sleep and screen time was not significant in Korean high school students.

The purpose of this study was to compare the dietary behavior of middle school and high school students who had working mothers with students whose mothers were not employed. Self-reports on their dietary behavior and one-day dietary records were obtained from 396 middle school students and 364 high school students using anonymous questionnaires. The results were summarized as follows; the students with working mothers were more likely to not to eat properly and their dietary behavior was generally inadequate, showing a greater irregularity for meals, more of a tendency to skip breakfast, less diversity of food intake, and a higher incidence of drinking and smoking. One-day dietary records obtained by 24k recall methods showed less diverse food intake and a higher rate of skipped meals in students with working mothers. Drinking and smoking were more prevalent among middle school students whose mothers were working than among those students with unemployed mothers, but in the case of high school student the difference was not significant. With more and more housewives seeking jobs, more attention needs to be given to the dietary and nutritional intake of their children, especially among middle school students. High school students seem to be less affected than middle school students by their mother's employment.

Purpose: This study was conducted to examine the prevalence of current smoking and the factors that influence current smoking among male high school students in Korea according to school type. Methods: Data were extracted from the Korea Youth Risk Behavior Web-Based Survey (2017) and multiple logistic regression was used based on complex sample analysis. The study sample comprised of 15,777 male high school students: 12,583 from general high schools (GHS) and 3,194 from specialized vocational high schools (SVHS). Results: The prevalence of current smoking was significantly higher in SVHS students (19.6%) compared to GHS students (12.6%). Low academic achievement, depressive symptoms, current drinking, and high household economic status were commonly associated with current smoking in male students from both school types. However, exposure to secondhand smoking at home, non-exposure to anti-smoking advertisement, exposure to tobacco advertisement, participation in smoking prevention or cessation education were related to current smoking in GHS students, while living in rural area was associated with current smoking in SVHS students. Conclusion: To reduce current smoking among male high school students, it is necessary to develop smoking prevention policies reflecting the factors associated with current smoking that are different by school type.
