The object of this study is to evaluate the Korean traditional food culture education program which was developed in the prior study. In order to evaluate the effect of the program on the students’ knowledge of traditional food culture and their food habit, the program was practiced for 82 students in 4 elementary schools located in Seoul and Kyungki province during 16 weeks from Mar 1, 2005 to July 23, 2005. The pretest and the post-test were performed using an evaluation tool which is composed of evaluation sections for the perception and knowledge of the Korean traditional food culture, Korean children’s food habit and food preference for the Korean traditional food and fast food. The validity of evaluation was proved through the control group in the pretest and the post-test. Descriptive analysis and paired t-test were performed using SPSS/WIN 12.0 Statistic Package in order to compare the results of the pretest with those of the post-test after the education. The perception of the students who took the class for the Korean traditional food was slightly improved (p<0.05) and their knowledge was also increased (p<0.001) after the education while no difference was found in the control group. Moreover, the subjects’ food habit (p<0.001) and their preference of the Korean traditional food (p<.05) were increased respectively but their preference of the Western fast food was decreased(p<.01). These results indicate that the education program evaluated in this study has the effect of altering the subjects’ food habit or food preference as well as of introducing the knowledge of the Korean traditional food culture.

The purpose of this study was to analyze the Jeju beach science camp program and to survey the participating students'' preference levels for the activities included therein. The camp programs were analyzed on the basis of the standards set for the HASA curriculum. The program's "manipulatory skill" area included many manipulatory and creative activities while the "inquiry area" included many basic and integrated inquiry activities. It was also indicated that the "knowledge area" included many activities appropriate for understanding concepts and principles while the "attitude area" included many activities appropriate for stimulating curiosity and enjoyment. Thus, it could be seen that the areas stipulated for the HASA curriculum were considerably consistent with the purpose of the science camp. The participating students showed preference for manipulatory and creative activities included in the program. They also preferred basic, inquiry level activities included under the area of "inquiry skills." It was identified that the students most preferred the conceptual stage included under the area of "knowledge" where they were required to grasp the common characteristics of events, things, and phenomena, as also the enjoyment stage included under the "attitude" area, where they were required to participate in pleasant science activities. These findings indicate that science camp programs should be composed of manipulatory and creative activities as well as activities that aim at basic research and the understanding of concepts.

Despite the fact that the national family planning program in korea has accomplished its primary goals of fertility reduction and universal contraceptive use, the induced abortion is still high and there has been an increasing trend in the population sex ratio at birth. It seems that the changes in the imbalance of sex ratio have originated from traditonal boy preference. This indicates that much of the current family planning program can be overhauled, so that the program quality could be better controlled, by preventing the number of unwanted pregnancies and the imbalance of sex ratios. This paper aims, therefore, to examine the determinants of induced abortion through the investigation of pregnancy outcomes and their changes over time and to study the interaction between induced abortion, boy preference and the imbalance of sex ratio in Korea. The abortion rate had increased rapidly until the mid-1980s when there were about the same number of abortions as live births. Thereafter, the abortion rate has been maintained at this high level. By parity it shows a much higher abortion rate for a higher parity at all time. From the first parity, the sex composition of previous children stands out as the most important factor in deciding the pregnancy outcome at all time. The probability of a pregnancy ending in an abortion increases substantially when parents already had a son. The decline of the desired family size and the sustained strong son preference has made the sex of children a more important factor in the determination of the pregnancy outcome. Women's education has had consistently positive effects on the probability of a pregnancy ending in an abortion, but the effect shows a steady decline over time. The premarital pregnancy and urban residence also increase the abortion probability. This study suggests that the main concerns of the family planning program should be to strengthen the social support policies so as to weaken the son preference value leading to a balanced sex ratio and prevention of induced abortions.

The menu planning is closely tied to the acceptability of the food and the satisfaction of the food service system to its client, therefore national school lunch program(NSLP) menu should consider the food preferences of the students. To provide appropriate information and guidelines about desirable NSLP menu planning, the comparison between the frequency of NSLP menus and food preferences of the students was performed, NSLP menus with cooking method of 776 meals were collected from 10 elementary NSLP schools in Seoul and Kyunggi province, and food preference data was surveyed with 1618 elementary school students from 4 NSLP schools in Korea in 1995. According to the cooking methods, NSLP menus served Kimchi(98.3%), rice(71.4%) and soup(71.1%) frequently. Based on the food groups, NSLP menus served vegetables most frequently(188%), followed by grains(101.4%), milk(100%), meat(57.3%), fruits(50.3%), and so on. By Spearman Rank Correlations analysis, the serving frequencies of vegetable side dishes(r=.33, p=.05) were positively correlated with the students' preference score. According to the cooking method, the serving frequencies of steamed dishes(r=1.0, p=.00), salads(r=1.0, p=.00), Kimchi(r=.85, p=.01) and rice one-dish meal(r=.80, p=.10) were positively correlated with the students' preference score. However, the serving frequencies of the main dishes(r=.13, p=.57) and soup group(r=.15, p=.57) were not significantly correlated with the students' preference score. Even though the serving frequency of fruit were negatively correlated with the students' preference score(r= -.80, p=.10). These results indicated that the NSLP menu planned the vegetable side dishes in accordance with the students' food preferences, but it planned the main dish, soup group, and meat side dish group discordantly. Therefore further efforts are needed to involve the preferred cooking methods for increasing the food acceptability. It could be used for the basic guidelines for menu planning of NSLP, and for the future improvement of NSLP in Korea.

This stusy was designed to develop nutrition education program for the primary school children served by the national school lunch program and to evaluate ist educational effects. Subjects consisted of 61 elementary school children(30 in the control group and 31 in the treatment group) in the 5th grade. Only the treatment group participated in a twelve-week nutrition education program. To evaluate the effects of the nutrition education program, the control and treatment groups were given a pretest and posttest for nutrition knowledge, food attitude, food habits, food preference and plate wastes before and after nutrition education. The results obtained are summerized as follows ; the nutrition knowledge test score (30.4) of the treatment group was significantly higher than that (17.4) of the control group after nutrition education . However, there was no significant difference between the two groups in food attitude test scores after nutrition education. We also did not find any difference induced by nutrition education or the food preferences of the treatment group. After nutrition education , the amount of plate waste of some menus were significantly decreased in the treatment group, but the amount of plate waste of the control group was not significantly changed. However, there was no significant difference in the post test scores above food habits between two groups. It was concluded that a twelve-week nutrition education program can improve nutrition knowledge and decrease plate waste but is not enough to change food attitude , food preference and food habits. It can besard that the two components of foodservice are nutritional foodservice and nutrition education. Foodservice management alone without nutrition education is hardly enough to improve the nutritional status of school children. The result of this study indicate that applying the nutrition education program to elementary school children who are served by the national lunch program can maximize the effects of the national school lunch program.

The purpose of this study was to observe the effect of nutrition education program that promote vegetable eating behavior of elementary school children. Three hundred education thirty two children were surveyed to understand food preference of them. The preferences for vegetables showed the lowest scores and fruits were the favorites of children, who aged ten to eleven, volunteered the program for six weeks. 31.3% of them were not in the state of underweight, overweight or obese. The nutrition education program include teaching guidances and materials in order to children to familiar with vegetables especially. To evaluate the effect of the nutrition education program, change of food preferences, nutrition knowledge and eating behavior of children were investigated before and after nutrition education. When the children finish the program, their preference scores for vegetables showed significantly higher than before the program(p<0.05, p<0.001), except tomato and laver that have high scores from the beginning(>1.5). Nutrition knowledge scores have significantly improved from 57.1 to 66.4(p<0.05). Eating habit for special food has improved(p<0.001) and breakfast skipping has reduced significantly(p<0.05). These results indicate that the nutrition education program can promote children to do balanced eating behaviors.

The following study has been conducted by carrying out the nutrition education program for preschool children and measuring the change in their food preference and nutritional knowledge. The 28 boys and 22 girls with the average height of $117.4{\pm}5.1cm$ and weight $21.8{\pm}3.5kg$ participated in the study. The favorite foods of the children were: meat (51.1%) being the highest, fruits (38.3%), carbohydrates (23.4%), while the least favored food was vegetables (75%). It indicated that 36.2% of the children were having unbalanced diets. The change in food preference after the implementation of the nutrition education program was the significant increase in preference in vegetables and fruits (p<0.01) and proteins such as meat, fish, eggs and beans (p<0.05). The differences in food preference among boys and girls were that the boys showed significant increase in vegetables and fruits (p<0.01) while there was a decrease in the simple sugar groups (p<0.01). Regarding girls, there were significant increases in vegetables and fruits as well as protein groups of meat, fish, eggs and beans (p<0.01). The changes in the nutritional knowledge of the preschool children after the implementation of the nutrition education program were scores for the fruits and vegetables group and carbohydrates group showed a significant increase while the scores for the oil and nuts group had decreased considerably. The average score on nutritional knowledge has significantly increased from 9.07 to 10.17 (p<0.01) and the score on the roles of the nutrients increased from 3.02 to 3.48 (p<0.05). The changes in eating habits of the children after the nutrition education were the answer for the change in eating habits of the children after the nutrition education was 'slight change' 61.4%. Also, the change in food preference was 'slight change' 61.4% and the improvement in nutrition education was 'slightly' 50%. According to the results of this study, it is evident that the change in eating habits and the acquisition of nutritional knowledge is very difficult, thus requiring consistent and prolonged education. Therefore, it seems to be best to include a more systematic and professional nutrition education program in preschool education. Also, the education for the parents should be implemented since the effect of education on children is greater when it is closely connected with the education at home.
