  • 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'.

  • This study attempted to analyze human brain responses toward visual content through EEG signals and intended to measure brain wave reactions of different age groups to determine the sexuality level of the media. The experimental stimuli consist of three different video footage (rated ages 12, 15, and 18) to analyze how subjects react in situations where they actually watch sexual content. For measuring and analyzing brain wave reactions, EEG equipment records alpha, beta, and gamma wave responses of the subjects' left and right frontal lobes, temporal lobes, and occipital lobes. The subjects of this study were 28 total and they are divided into two groups. The experiment configures a sexual content classification scale with age or gender as a discriminating variable and brain region-specific response frequencies (left/right, frontal/temporal/occipital, alpha/beta/gamma waves) as independent variables. The experimental results showed the possibility of distinguishing gender and age differences. The apparent differences in brain wave response areas and bands among high school girls, high school boys, and college students are found. Using these brain wave response data, this study explored the potential of developing algorithm for measurement of age-specific responses to sexual content and apply it as a film rating.

  • This study was conducted to identify and compare the stressors and coping behaviors of high school students who experienced suicidal ideation vs those who do not. Method: The data were collected from 1,441 high school students living in the middle region of Korea. Researchers collected the data using Adolescent Stress Inventory and Adolescent Coping questionnare from February to May of 1999. Data were analyzed using X2, T-test. Result: A significant proportion (31.9%) of subjects had thought about suicide during the past 6 months, 297 girls (35.3%) and 163 boys (27.2%). Major stressors of subjects who experienced suicidal ideation were academic problems, conflicts between family members, and changes in sleeping or eating patterns. Conflicts with family members contributed to have suicidal ideation. There was no significant difference in helpful coping behaviors between the two groups. The group who experienced suicidal ideation had lower scores and fewer coping behaviors. Boys perceived more stressors and had fewer helpful coping behaviors than girls. Conclusion: It is necessary to develope school-based suicide prevention programs. Our findings suggest that the program should focus on problems related to studying and conflicts within the family.

  • The purpose of this study was to identify the preferable motivation types in science-learning and to find out the relationship between these types and scientific achievement of students in the secondary school. The subjects of the study were the second grade 581 students sampled by random cluster sampling method in three middle schools and three high schools. Three motivation types in science learning were analyzed, and they were named to task-orientation, ego-orientation and work-avoidance. From our results, secondary school students preferred task-orientation and work-avoidance to ego-orientation. In the case of task-orientation, high school students, especially in male group, had much preferable tendency than that of middle school students (p<0.001). It is interpreted that, as the level of scientific content of texts or the cognitive level of students were higher, a preference for the motivation type was focused to the task-orientation, especially in male group. In the case of ego-orientation, the female group showed much preferable tendency than that of male group in middle school (p<0.05). However, the female group in high school students was not different from the other groups in this motivation type. In the case of work-avoidance, there were not only a significant difference between males and females in the middle school (p<0.001), but also difference between middle and high school students in female group (p<0.05). It showed that female group had much preferable tendency than that of male group, and this tendency was decreased to the higher grade students in secondary school. From the analysis of correlation between motivation types and scientific achievement, task-orientation and work-avoidance were correlated to the scientific achievement. Its results were interpreted that the scientific achievement could be accomplished by the external motivation stimulus as well as the scientific content of texts. The task-orientation were comparatively correlated to the intelligence quality. It means that the students having high intelligence quality showed much preferable for the task-orientation.

  • Since the effect of environmental education at class using textbooks or materials related to environment is limited, the importance of activities for field experience is getting increased day by day. Thereby, the education tends to change into the type of education providing students with direct environmental experience. Students attending the science high school have excellent aptitude and ability for science and will lead the development of science in the future. Now it is urgent to develop various experiential programs which are helpful for them to establish desirable values on environment. However, the field of environmental education that allows science high school students equipped with ample environmental knowledge to improve environment sensitivity and have proper environment awareness is quite restricted as of now. Natural exploration activities are the programs which provide science high school students having lack of chance for environmental education with good opportunities to contact nature and also play significant roles in arousing their interest in issues related with environment. Therefore, it is thought that they will let science high school students explore the natural features of Korea, understand the importance of preserving environment and ecosystem profoundly, and encourage environmental awareness and will of environmental practice. Thereupon, with the study subjects of 121 first and second graders at U Science High School, this article analyzed their recognition of the necessity for environmental education and environmental pollution problems before and after the natural exploration activities, and conducted a survey on their satisfaction after the natural exploration activities and analyzed it. The result of this research is as follows. First, it was shown that the natural exploration activities were effective to raise the science high school students' awareness of issues related with environmental pollution. Second, the natural exploration activities had effect upon enhancing the students' willingness of environmental practice. Third, there was statistically significant correlation between the science high school students' satisfaction with the natural exploration activities and their achievement in the science subject. Fourth, there also was a statistically non or weakness significant correlation between their satisfaction with the natural exploration activities and preference for the science subject. In particular, it was found that students preferring biology indicated higher satisfaction.

  • This research was carried to investigate the food preference of students, from elementary school, middle school, high school, university and industrial workers on Jinju, Sacheon and Jinyang by age and sex. The results were obtained as follows. In case of rice as the stationary food, plain white boiled rice showed the highest preference among all the groups. Most of groups liked most of one-dish meals such as kimbab, fried rice with kimchi, dumplings and bibimbab, especially the elementary school students and middle school students. On the other hand, high percentage of industrial workers disliked the western food such as pizza, hamburger and sphagetti. Most of subjects liked jajangmun, nangmun and bibimgooksu as noodles. As the side dishes generally they prefer the soup to stew. Male prefer the soup with beef and female prefer soup with vegetables. Stew with kimchi and stew with soybean paste showed high preference among most of groups. Most of broil food showed high preference, and students prefer meat to fish as broil cooking materials especially younger students. As a general they liked soybean sprout, spinach and wild sesame leaf as namul cooking method and they liked korean cabbage kimchi, chonggak kimchi, kackdoogi and dongchimi as kimchi. As a dessert subjects liked most of fruits and they liked yoghurt, fruit juice, milk, sikhae and soda as drinks generally. On the other hand snacks such as cooky, candy, cake, corn, rice cake, sweet potato have the lowest percentage preferance as a dessert, but students from elementary schools showed the highest preferance to sweet such as cooky, cake and candy than any other group. These food preferance results showed some nutritional problems especially young age students. They should eat more green-yellow vegetables, liver food and dried small sardine and they should reduce snacks such as candy and cooky and soda drinks. Therefore it is necessary to conduct nutrition education by parents, teachers and dietician together to improve their food habits and their health.

  • Purpose: This study aimed to assess the effect of rowing ergometer training on the aerobic capacity and strength of male high school students over a 12-week period. Methods: Fourteen high school students volunteered to participate in the study. The subjects were divided into two groups: seven subjects in the experimental group and seven in the control group. The subjects in the experimental group performed rowing ergometer training for 75 min per session at three days a week for 12 weeks. The exercise intensity set the maximum heart rate (HRmax) from 40% to 80%. Aerobic capacity was measured by ventilation, cardiac output, and oxygen intake per body weight. Strength was measured by grip strength and back strength before and after training. Results: A significantly increased ventilation (p=0.01), cardiac output (p=0.01), and oxygen intake per body weight (p=0.00) were found in the experimental group. A significantly increased grip strength in the right and left hands (p=0.00, 0.00) and back strength (p=0.04) were observed in the experimental group. Conclusion: Rowing ergometer training can be an effective combined exercise for aerobic capacity and strength of high school students.

  • This study was undertaken to identify factors affecting school food waste generation using a questionnaire. The subjects were 254 high school students (male; 156, female; 98) in Sacheon, Gyeongnam divided into three groups of low (${\leq}1/week$), moderate (2~3/week), and high (${\geq}4/week$) according to the frequencies of food waste. The questionnaires consisted of general characteristics, anthropometric values, dietary habits, health-related behaviors, self-perceptions of food waste, snacking patterns, and nutrition knowledge. The main reasons behind food waste were 'too much food' in the low (20.9%) and moderate (32.2%) groups, and 'no appetite' in the high group (p<0.01). The main types of food waste were rice (44.2%) > fish (18.6%) > vegetables (14.0%) in the low group, rice (54.2%) > Kimchi/vegetables (15.3%) in the moderate group, rice (56.0%) > vegetables (20.0%) > Kimchi (16.0%) in the high group (p<0.01). School food waste was significantly affected by age, gender, monthly allowance, school grade, weight, BMI, regularity of meals, time of meals, type of breakfast, starting age of smoking, and cost for snacking.
