The purpose of this study was to investigate high school students' perceptions of biotechnology. Participants in this study were 9th and 10th grade students who were enrolled in high schools in Gyeonggi Province. The survey instrument used in this study was a 26-item questionnaire that was designed to measure students' perceptions regarding biotechnology. The study revealed that students' perceptions were positive toward the use of biotechnology on biological objects such as plant, grain and microbes. However, their perceptions were negative toward the use of biotechnology on humans and animals. Male students' perceptions were more positive than female students and there were significant differences between male and female students(p<.01). The study also revealed that male and female students had positive perceptions about the use of biotechnology in the development of beneficial products. However, male students' perceptions were more positive than female students(p<.01). Female students' perceptions were slightly more negative than males and they indicated a measure of caution in the development of beneficial products using biotechnology. Regarding the reliability of biotechnological information acquired from food companies, TV broadcasters, and entertainers, male and female students tended to be highly negative. Students perceived that environmental, religious and ethical issues did not affect the use of biotechnology when asked the effect of these factors on the use of biotechnology. They perceived that food safety and genetic factors of microbes did affect the use of biotechnology. Thus, the study findings suggest that teaching and learning strategies based on the differences of perceptions between male and female students of this study be established and the use of media, development of teaching method and materials be promoted in order to enhance student's performance in environmental education.

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.

In this study, high school students' environmental conceptions and attitudes, and their relationships with affective variables (self-esteem, enjoyment of science lesson, and leisure interest in science) were investigated. Students' environmental conceptions were found to be low, and male students' environmental conceptions were higher than female students. However, the environmental attitudes of female students were more positive than those of male students. There were no differences between male and female students in the ecocentric attitudes, but male students had more egocentric attitudes than female students. Students of higher prior science achievement level possessed higher level of environmental conceptions than their counterparts. Among the affective variables studied, leisure interest in science was significantly correlated with environmental attitudes.

This study surveyed food intake and preferences for breakfast among 167 male and 152 female middle school students in Incheon. Most students were in a normal range with respect to body mass index (BMI; 18~22.9). Most of the students spent 10~20 minutes to finish their breakfast, and female students skipped breakfast more frequently than male students, with major reasons of not being able to spend enough time for breakfast and low appetite. Steamed rice(bap) was the most frequently consumed food for breakfast. Students ate vegetables and fruits for breakfast the most frequently, followed by milk and milk products, meat, fish, egg and beans, and cereals. The most frequently consumed food among protein sources was eggs. Male students had foods except vegetables and fruits more frequently than female students for their breakfast. Female students were more highly aware of the importance of breakfast on their health than male students. Preference on different food groups was significantly higher in male students than female students except vegetable salad and fruit juices. The results suggest that breakfast skipping of middle school students can be reduced by aggressively reflecting food preferences of the students to breakfast menu and appropriate nutritional education for students and their mothers.

The purpose of this study was to determine the awareness and preference relating to traditional food and yaksun food by university students majoring in culinary art and foodservice in the Daegu and Gyeongbuk area. This research carried out an investigation on 492 (male 257 and female 235) students. 'Awareness of traditional food' was gained through school education in male students (37.4%) and female students (46.7%). For 'the most-favored traditional food', 260 (male 138 and female 122) students most often responded galbijjim, followed by bibimbap, bulgogi, and kimchi. For 'the part that requires the attention most in improving traditional food', variety of taste received the highest votes by 109 male students (42.4%) and 98 female students (41.7%). For 'awareness for yaksun food', the most popular paths were TV, newspaper and the Internet in 123 male students (47.9%) and 139 female students (59.1%), where as 97 students answered school education (19.7%). For 'the part that requires the attention most in developing yaksun food', variety of taste received the highest votes by 103 male students (43.8%) and 106 female students (41.2%), which was the same result for the development of traditional food. For 'awareness on the possibility of popularization of traditional and yaksun food', needs for food development received the highest score of 3.99 (male 3.99 and female 3.99) by 5-point Likert measurement. In conclusion, high awareness levels of health, traditional food, and yaksun food in university students in Daegu and Gyeongbuk majoring in food-service will contribute to a healthy food culture. Further, this research will have a large impact on development of various convenience foods in the food-service industry as well as home.

Objectives: The purpose of this study was to investigate the relationship between stress levels and eating habits in adolescents. Methods: A total of 453 male and female high school students were surveyed to ascertain their stress levels, Nutrition Quotients for Korean Adolescents (NQ-A), and stress-related eating behavior. Results: The average age of the subjects was 18 and they were mostly from nuclear families. Their average daily conversation time with their parents was between 10 to 30 minutes. The average sleep time for female students was observed to be less than that of male students. The satisfaction level of academic achievement of female students was significantly lower than that of the male students (P < 0.001). The average stress level score for female students was 2.7 out of 5, which was significantly higher than the male student's score of 2.4 (P < 0.001). The eating speed of male students was related to stress levels. Both male and female students ate more and craved spicy food when under stress. All male and female students had significantly ascending NQ-A scores rising in the order of stress from 'low level' to 'medium level', to 'high level' (P < 0.001). There was a significant negative correlation between the stress score and the NQ-A score adjusted for general characteristics (r = -0.29, P < 0.001). Conclusions: Since stress and NQ-A were negatively correlated in high school students, higher stress levels can be associated with irregular eating habits and negative eating behavior. Therefore, stress management and nutrition education focusing on stress status are needed for adolescents.

Objectives: This study was performed to examine dietary habits, life stress, and nutrition knowledge among high school students in Gyeonggi area. Methods: A total of 431 high school students (210 males, 221 females) in Gyeonggi area participated in this study from November to December of 2011. The study was a questionnaire-based survey that included dietary habits, dietary attitudes, life stress, and nutrition knowledge. Results: Body weight, height, and body mass index were all higher in male students than in female students (P < 0.001, respectively). For dietary habits, the average score (P < 0.01) and scores for considering combination of food groups (P < 0.05), eating green and orange vegetables (P < 0.05), eating meat, fish, eggs, or beans everyday (P < 0.05), drinking milk (P < 0.001), and eating seaweed (P < 0.01) were higher in male students than in female students. For dietary attitudes, the average score (P < 0.05) and scores for the five items were significantly different between male and female students. Male students showed a significantly lower nutrition knowledge score than female students (P < 0.05). Life stress score of students largely was attributable to academic factors, and female students showed higher stress score for academic, personal, and surrounding environmental (P < 0.05, respectively) factors than male students. Dietary habit score (P < 0.01) and nutrition knowledge score (P < 0.05) in female students as well as dietary attitude score (P < 0.05) in male students were negatively correlated with life stress score. Dietary habit scores in male and female students were positively correlated with dietary attitude score (P < 0.01, respectively). Need for nutrition education was significantly higher in female students than in male students (P < 0.05). Conclusions: This study provides basic information on dietary habits, dietary attitudes, life stress, and nutrition knowledge according to sex and suggests gender-specific practical nutrition education programs to address undesirable dietary habits and attitudes in students with higher stress levels.

Mathematical, spatial, and verbal abilities are important for future engineers to succeed in the STEM disciplines. The purpose of the study is to assess engineering students' spatial abilities and analyse the relationship with mathematical achievement, verbal achievement, and gender. On the mental rotation tests, 65% of male students demonstrated a substantial level of spatial abilities. But only 30% of female students exhibited spatial skills at the same level as their male colleagues. The correlations between mathematical - spatial - verbal abilities are found to be negligible. When spatial visualization ability was plotted according to the mathematical achievement level, there was no difference in the mean spatial abilities score. But when mathematical achievement score was plotted according to the spatial abilities, there was a noticeable difference. Regression analysis confirmed that female students' mathematical achievement increased as spatial abilities improved. This phenomenon was not observed for male students. It's because male students' spatial ability already contributed to their mathematics achievement. So spatial ability can be regarded as one factor for the gender differences in mathematics achievement. The gender gap on spatial abilities and math achievement is large among high achieving students. For example, there was a 4.3 to 1 male - female ratio and 3.4 to 1 male - female ratio among students scoring 99th percentile in spatial visualization test and scholastic aptitude test-math.

The purpose of this study is to assess folate intake, and serum and red blood cell (RBC) folate concentrations, and investigate the association between folate status and health-related behaviors among Korean college students. A total of 169 students, aged between 18 and 27 years, participated in this study. Dietary intake data were collected by trained interviewers using a 24-hour recall method for three non-consecutive days in 2009. Information on health-related behaviors was obtained by a self-administered questionnaire. Serum and RBC folate concentrations were measured by microbiological assay. The average intakes of folate were $456{\mu}gDFE$ and $347{\mu}gDFE$ in male and female students, respectively. While the average serum folate concentration was significantly lower in male students (8.9 ng/mL) compared to female students (12.5 ng/mL), RBC concentrations were not significantly different between male (398.6 ng/mL) and female students (405.3 ng/mL). In male students, low serum folate concentrations were associated with total folate intake less than the Estimated Average Requirement, non-use of folic acid supplements, smoking, alcohol drinking at least once a week and low physical activity. In female students, low serum folate concentrations were associated with smoking and alcohol drinking at least two drinks at a time and BMI ${\geq}25$. Alcohol drinking and low physical activity were also associated with low RBC folate concentrations in both male and female students. In order to improve folate nutritional status of college students, the practice of desirable health-related behaviors, such as non-smoking, moderate alcohol drinking, regular physical activity, and maintenance of healthy BMI should be encouraged along with consumption of folate-rich foods and supplements.
