This study was carried out to evaluate the effect of mothers' attitudes on preparing baby foods for their children's food habits and development. The subjects were allocated to 419 preschool children, aged 3 - 5 years. This study surveyed by questionnaire, which was answered by the children's mothers. Subjects were classified by two groups, active and passive, based on their mothers' weaning attitudes. In the active group, mothers tried to make a variety of foods for preparing the baby foods, whereas mothers in the passive group didn't try to make it too much. Family income was higher in the active group and the subject' mothers had more jobs than those in the passive group, whereas their parent's education levels showed no differences. According to Rohrer index, 2.6% of subjects were obese in the active group, whereas 7.7% in the passive group. These data were shown significantly different between the groups. There were no differences in mother's food habits and breast-feeding versus formula feeding between the two groups. However, children's food habits were shown statistically different between the two groups. Higher regularity of meals, higher frequencies of snacks at home, higher frequencies of fruit, com, sweet potato as a snacks and less instant foods were revealed in the active group more than in the passive group. The major problem of children's food habits was an unbalanced diet (52.7%) and the major reasons for unbalanced diet were the taste (58.7%) and the texture (23.2%). The active uoup used more fruits and vegetables than the passive group. Also there were significant differences to solve problems of children's unbalanced diets. In the positive group, 14.4% of mothers tried to develop new cooking methods for solving the problem of an unbalanced diet, but 8.2% did in the passive group. furthermore, 2.3% of mothers in the positive group removed unpleasant items of the food, whereas 6.9% did in the passive. The average nutritional knowledge scores on a 10 scale were 7.2 and 6.9 in active and passive groups, respectively, and they were statistically different. Mothers among the active group explained the knowledge for food and nutrition to their children more than those in the passive group. These results suggest that mothers' attitudes for baby food are an important factor for forming their children's food habits. Therefore, it is necessary to develop a nutritional education program, materials and new recipes for a variety of baby foods to mothers.

The purpose of this study was to provide basic data for nutritional education for juveniles' desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was $20.1kg/m^2$. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, "I am in the middle", "I like them", "I dislike them", "I like them very much", and "I dislike them very much" in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

This study conducted a survey to analyze awareness, preferences, and the current state of consuming environmentally friendly organic food while eating-out in 435 adults aged 20 and above in Daegu, Korea. Most subjects (95%) showed awareness of environmentally friendly organic food, and 88.5% of subjects answered environmentally friendly organic food is 'needed'. The percentage of eating out for families was 58.9%, and 49.0% of subjects said they eat out one to three times per month on average. In addition, subjects preferred a price range between 10,000 and 20,000 won per person when eating out, and they mostly favored Korean restaurants when ordering environmentally friendly organic food. Analysis of awareness of environmentally friendly organic food showed that among 'health' factors, 'environmental' factors, 'social' factors, and 'dietary essential' factors, 'health' factors showed the highest percentage for awareness. A survey on preferred foods by gender showed that both genders preferred vegetables the most. The results show that subjects in their 20s and 30s favored vegetables and fruits while subjects in their 40s preferred vegetables and grain animal products. Analysis of preferred types of environmentally friendly organic foods showed that men preferred polished rice while women preferred brown rice. Subjects in their 20s and 30s preferred strawberries, whereas those in their 40s preferred cherry tomatoes and those in their 50s and above favored tomatoes (p<0.001). Among root and tuber crops (63.4%), sweet potato was the most preferred. Among fruits, subjects preferred apples while among special crops, they most preferred oyster mushrooms; both genders preferred Korean beef. The most preferred livestock product of subjects in their 20s was pork, whereas subjects in their 30s preferred Korean beef. Subjects in their 40s preferred Korean beef and pork in the same proportions, whereas subjects in their 50s and above favored eggs the most.

Objectives: Vegetables are the most left over side dishes in school lunch programs. This study intended to analyze the differences in preference for vegetables among the students of different age groups in order to determine potential ways of increasing vegetable consumption in this study group. Methods: A total of 308 primary to university students in Gyeongbuk area were recruited and a questionnaire-based survey was conducted. The preference score (7-Likert scale: very much dislike (1)~so-so (4)~like very much (7)) and intake frequency (5-Likert scale) of 48 kinds of vegetables in 4 vegetable groups, such as vegetable (fruit-, root-, leaf-, and stalk-vegetable), seaweeds, mushrooms, and kimchi were investigated, and data were analyzed by SPSS WIN (ver 12.0). Results: The preference scores of vegetables except for seaweeds were significantly different among school groups, university was the highest, followed by high school. Primary and middle school students showed the lowest preference score, especially for leaf- and stalk- vegetables. The preference score for seaweeds was the highest of 5.28, followed by kimchi of 4.99. With regard to kimchis, the preference score was the highest in university', followed by high school, middle school, and primary school' was the lowest. The number of vegetables with < 4.0 preference score was the highest in primary school of 16, 15 in middle school, 11 in high school, and 7, the lowest in university. The vegetable with preference score of < 4.0 in all 4 school groups were mallow, chard, bud, radish leaf, mugwort, butterbur and sweet potato stalk. With regard to the intake frequency of vegetables, kimchis, an indispensable part of the Korean diet, was the highest of 2 times/day, followed by cooked vegetables of 1.5 times/day. The correlation coefficients between preference scores and intake frequencies were statistically significant in all groups of vegetables. As for the coefficient of variation (CV) of preference score, primary school' was the highest and university' was the lowest. The number of vegetables with high CV and high inexperience were highest in primary school students. Conclusions: Providing more opportunities for consuming a variety of vegetables, such as leaf- and stalk-vegetable, it may be possible to increase vegetable consumption, especially for the primary school students.

Microbiological populations and the sterility of commercial powdered products treated with gamma irradiation at 0~10 kGy were investigated before using them as ingredients for a non-cooked Saengsik product. We evaluated a total of 14 powdered products: 8 powdered cereals, 3 powdered tubers, and 3 powdered leafy vegetables. The total numbers of bacterial populations in non-irradiated powdered cereals, tubers, and leafy vegetables were 2.7~6.9, 5.6~6.0, and $5.3{\sim}6.8\;log\; CFU{\cdot}g^{-1}$, respectively. Moreover, coliform bacteria were not indicated in adlay, millet, germinated brown rice, soybean, and mulberry leaves powder within detection limit ($2.0\;log\; CFU{\cdot}g^{-1}$). The number of Bacillus cereus exceeded $3.0\;log\; CFU{\cdot}g^{-1}$ (the maximum limit for Saengsik products) in all samples, excluding perilla seeds, buckwheat, barley, oat, potato, and Jerusalem artichoke powder. However, a dose of 6 kGy of gamma irradiation reduced the microbiological populations in all samples, and all the powdered products met the microbial requirements for Saengsik products. Futhermore, it was confirmed that all microorganisms in the 9 powdered products, except fermented brown rice, sweet potatoes, and 3 leafy vegetables, were sterilized by 10 kGy of gamma irradiation.
