The purpose of this study was to assess pro-environmental behavior of elementary school students by school year and gender and to investigate the relationships of their emotional affinity toward and intellectual curiosity about life, and experiences about nature and life with the pro-environmental behavior. A total of 436 elementary students participated in the study: 189 3rd grade; 247 6th grade students, and 233 boys; 203 girls. The variables were measured by using a self-report questionnaire with 5-point Likert scale items. The results showed the levels of pro-environmental behavior of the 3rd grade students and the girls were higher than that of the 6th grade and the boys, respectively. Their pro-environmental behavior was significantly related with all measured variables. However, it was found that the direct predictors of their pro-environmental behavior were the intellectual curiosity and the indirect experience, while the emotional affinity and the direct experience did not have a direct impact on the behavior. The predictive power of the intellectual curiosity and the indirect experience for their pro-environmental behavior was higher in 3rd grade than 6th grade. While the indirect experience was a stronger predictor of the boys' pro-environmental behavior than the intellectual curiosity, the curiosity was a stronger predictor of the girls.

This study was designed to evaluate the relationships among snack intake, obesity index, and blood parameters in obese elementary school children. Anthropometric measurements, nutrient intake from meals and snacks, serum cholesterol, glucose, GOT, GPT, and hemoglobin levels were obtained 36 obese elementary students (boys=28, girls=8). The average age, height, weight, % body fat, and obesity index were 11.9 years, 145.5cm, 53.5kg, 45.7%, and 32.4%, respectively. The mean energy intake was 1,818.7 kcal in boys and 1,818.1 kcal in girls. In addition, the energy intake from snacks was 470.4 kcal in boys and 479.4 kcal in girls. The levels of plant fat (p<0.05) and cholesterol (p<0.001) consumed during snacks (1,000 kcal per energy intake) were higher than those consumed during meals. The serum cholesterol, glucose, and hemoglobin levels were 177.4 mg/dL, 90.4 mg/dL, and 14.5 g/dL, respectively. In addition, the levels of serum GOT (p<0.001) and GPT (p<0.05) were higher in boys than in girls. Height was positively correlated with food intake (p<0.05), snack intake (p<0.05), and energy intake from snacks (p<0.05). Based on these results, further studies are needed in order to investigate the relationships among various aspects of snacking and obesity in elementary school children.

This study was conducted to investigate the influence of obesity stress on the eating behavior of elementary school students. Using a questionnaire, 300 students in the sixth grade from 2 schools in Kyunggi-do were surveyed (Boys: N=145, Girls: N=155). Data analysis was managed by SPSS software (version 13.0). The link between obesity stress and eating habits or behaviors was dependent on physical discomfort. There was also a large group of students experienced irregularity in their meal times during the day. Furthermore, there were significant differences in mealtime among boys under psychic stress caused by obesity. In the case of dairy intake during breakfast, the significant signs of obesity stress for were physical discomfort for boys and psychic stress for the girls. It was found for both boys and girls that more frequent midnight snacking decreased the efforts to overcome obesity stress. Therefore, a professional nutrition program that can educate school children must be implemented both in school and at home. In addition to overweight or obesity children, normal weight and underweight children can also benefit from this program that includes health counseling for weight and eating behaviors.

The purpose of this study was to determine the relationships between table attitudes(or table manners), nutrition knowledge, eating/snacking habits, and BMI in elementary school children. For the study, 350 [4~6th grade] elementary students were recruited and surveyed. Each response for 10 questions regarding table attitudes was scored by a 5-point scale(5 points=strongly agreed & 1 point=strongly disagreed) with a total score of 50. The reliability of 10 questions about nutrition knowledge was validated using Cronbach's ${\alpha}$(Cronbach's ${\alpha}$=0.80). Total scores for table attitudes were significantly different between the boys and girls(p<0.05). The total score for nutrition knowledge was significantly higher in the girls(7.67/10.0), compared to the boys(7.35/10.0)(p<0.05). The children showed high rates of incorrect answers in questions regarding the function or importance of specific nutrients. No significant differences between the boys and girls were found for places of snack purchase, or pocket money/day. Most of the children answered spending less than 800 won of pocket money per day. More boys preferred meals with meats and disliked Kimchi and vegetables compared to girls, and the differences were statistically significant. The score for table attitudes was significantly and negatively correlated with nutrition knowledge and gender. No significant correlations between BMI and table attitudes or nutrition knowledge were shown.

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 informations concerning knowledge, value and consumption pattern for rice foods of elementary schoolchildren (630 boys and 550 girls in 5th or 6th grade) were investigated in Changwon and Gimhae of Gyeongnam province. They were asked based on knowledge, one’s value and intake frequence of rice foods by questionnaries. Menus for 3 days including 2 weekdays and 1 weekend day were taken from 136 students (77 boys and 59 girls) in two Elementary Schools in Changwon and Gimhae to know intake reality of rice product. The purpose of this survey was to find the way of encouraging rice intake and preference which now seemed to be low because of simplified, westernized eating habits, and to provide basic information needed for inheriting and improving our traditional cooked rice centered eating culture. The results are summarized as follows. The knowledge of rice was positively correlated to the one’s value (r=0.365, p<0.001) and the preference (r=0.132, p<0.001), the one’s value was positively correlated to preference (r=0.409, p<0.001). The score of knowledge for rice was 12.8 points out of 20, the girls get points(13.12) significantly higher than the boys (12.53) (p<0.01). One's value about rice foods was 37.35 points out of 50 what is relatively high. They have eaten cooked rice type food for 2.24 times per day. Both boys and girls in Changwon and Gimhae area were having cooked rice type food significantly more during weekdays compared to weekends (p<0.001) by 3 days food record. According the results, we can see the possibility that schoolchildren can be encouraged to eat more rice foods by nutritional education to go with the development of various programs.

The purpose of this study is to find out the differences (if any) and the causes of preferences for science between elementary school boys and girls. Another purpose of this study is to find out when such differences in preference begin and what their causes we. Fourth, fifth and sixth grades from elementary school A in Gyeongg-gi Province participated twice in research surveys on preference levels in science with education, career course and personal experience taken into account. A total of 997 survey responses, (excluding no responses or half-hearted ones) were selected for comparative analysis. The analysis methods used were frequency analysis, cross stabs and one-way ANOVA Analysis which depended on survey items. The results of this study show that preference levels in science are 61.7% and the difference of preference levels in science between boys and girls are 31.2% and 30.5% with boys showing higher percentages in science preference levels than girls(p<.01). Moreover, the results also show that the point in which changes in preference level in science emerges is from fifth and sixth grades. Therefore, the gender difference in preference levels in science begins with fifth grade students, with science being slightly more favored by boys. finally, the main causes in gender differences seems to be the experiment participants' levels, scientific education textbook preference level, interests in science class, and plans for the future that are related to field of science. Among these causes, interests level in science class and preference levels in science are closely related.
