Recently, local foods have drawn significant attention due to their intrinsic merits. Such foods not only have commercial potential, but also cultural value. Therefore, local foods must be well-maintained and fostered, and a comprehensive plan to develop them must be devised. In this aspect, various factors such as dietary attitudes, perceptions and concerns affecting their development should be considered. The present study was designed to investigate via survey the dietary attitudes, perceptions and concerns towards local foods among married women in Jeollabuk-do. The number of subjects was 434. According to the results, the highest frequency for consuming local foods was '1~3 times/month' for all ages. For the number of local foods subjects had ever tried, '7~8' was the highest overall with 36.8%, followed by '5~6', '3~4', '9~10', and '0~2' with 27.4%, 17.9%, 10.3% and 7.6%, respectively. However, there was a statistically significant difference according to age. The higher the person’s age, the higher the number of local foods they had tried. A similar pattern was shown in the number of local foods subjects had ever cooked. For those in their 20s and 30s, the highest number was '0~2', with 70.8% and 53.0%, respectively, while for those in their 40s the highest number was '3~4' with 38.5%, and for those above 50s it was '5~6' with 31.4%. Most of the subjects realized the need to advance the development of local foods. There were differences among the subjects for certain aspects concerning progression and development, opinions on the major drawbacks of local food development items served more often at home, and different views by age on taste modifications according to modern concepts. From this study, it can be concluded that the utilization of local foods increases with age, and the view that local food development should be based on the recovery and/or maintenance of original tastes becomes more prevalent with age.

This study was performed to investigate the recognition on preprocessed foods among dietitians employed in 106 elementary school foodservices in Inchon by questionnaire from December 11th to 28th in 1999. Number of cooks in school foodservices increased significantly(p<0.01) with the number of children to feed, and 8 or 9 cooks were the most typical number(36.79%). Most(93.4%) of the subjects understood that it is necessary to use the preprocessed foods and they considered the food hygiene as the most important factor. Many subjects(89.62%) responded that the lack of cooks and cooking equipment was partly solved by using preprocessed foods and the expected reductions in personnel and waste through using preprocessed foods were $15{\sim}20%$ (38.68% of the subjects) and 20-30% (41.51% of the subjects), respectively.

A group of 132 pre-school children with a mean age of six years and one month was the subjects of this investigation. These children were members of three nursery schools locating in Kwang-ju city. Each child's mother replied to a questionaire which included 42 food items and 4 questions. The results showed that the food preference of each child was variable and the group as a whole expressed more positive than negative feelings. The average number of foods liked per child was 22.9(range: $7{\sim}42$) among 42 food items. Peach, Apple, Strawberry, Laver, Egg, Tomato, Sweet Potato, Tangerine Orange and Beef were ranked in descending order of 'like' ratings. The average number of foods refused was 4.9 (range: $0{\sim}25$). Onion, Liver, Red Pepper Leaf, Root of Bellflower, Taro, Wild Seasame Leaf, Egg Plant, Cabbage, Water Cress and Bracken were ranked in descending order of 'refuse' ratings. The odor of hurting feelings, the hot taste and the flabby texture were the reasons why the children refused these foods. The average number of foods unexperienced was 4.4 (range: $0{\sim}14$). Kidney, Dried Small Whitebail, Tangle (DA SHI MA), Liver, SA RI Mushroom, Acorn Mook, Dried Fragrant Mushroom, Pine Agaric, Root of Bellflower and Ped Pepper Leaf were ranked in descending order of 'unexperience' ratings. Children's 'like' rating toward total foods was 57.3% and the 'refuse' rating was 11.7%. Among eight food groups, fruits showed the highest favority (91.4%) and mushroom showed the least (25.9%). The difference between male and female in the preference of total foods did not showed significant level. But the difference were significant in those of individual food groups; other vegetables, green and yellow leafy vegetables, mushrooms(above, p.<01), fishes and shellfish and sea weeds (above, p<.05). Children who had experienced meals missed rated 59.1% and 34.1% of these children missed meals once a week. The main reason for maels missed was due to the heavey snacks before meal time. Children who had snacks twice a day rated 45.6%. Main foods used as their snacks were starch foods (Cake, Biscuit, Sweet Potato) and citrous foods (Fruits, Apple, Tangerine).

This study was conducted to examine contribution of specific foods to absolute intake and between-person variation in nutrients consumed by 2037 adults living in Korean rural area using one day 24-hour recall method. To measure contribution of food to absolute nutrient intake, all foods consumed were ranked by percentages calculated as the sum of the nutrient intake contributed by a given food divided by the total nutrient intake from al categories. To assess between-person variability in nutrient intake, stepwise multiple regression analysis was used with total nutrient intake from al foods as the dependent variable and the nutrient amount from each of all foods as independent variables. The kind and the number of foods necessary to account for the variation in nutrient intake among persons varied significantly depending on the nutrient. The nutrients contributing more than 80% of total intake with a few number of food items were ${\beta}$-carotene(ll), vitamin C(15) and vitamin A(16). Foods sometimes overlooked as important sources were found in some instances to be quantitatively important to population intake. Even though rice and Korean cabbage kimchi do not contain much nutrients in quantity, they made a major contribution to most nutrient intake of subjects because of large serving size and high frequency of intake. The food items and contributing order for between person variance was different from those of absolute intake. A large fraction of the variability of nutrient intake in this population was explained by a small number of foods. Fewer foods were required to explain a given proportion of the between-person variance in intake than to account for the same proportion of the popylation\`s total intake. These data may be useful in the development of dietary assessment instrument and in nutrition education. (Korean J Nutrition 33(8) : 882-889, 2000)

The purpose of this paper was to grasp some aspects of use of imported foods at the rural homes with the growing generation. So we put some questions to the 399 middle school and high school students. The results were as follows: (1) The number of the homes using the imported foods, which marks 56.9% of the whole, was higher than the number of the homes not using the ones. (2) Even though the use of imported foods had no relation with the occupations of the student's mothers, the degree of living quality, the situations of food consumption, and so on, however the use ratio was high at the homes of middle class. (3) The students of the home of using imported foods favored the traditional diets, and marked 63% of the objective students of investigation. The students who like the western style of diets marked the high frequency of the use of the imported foods. On the other hand, the students who like the Chinese foods used the meat and fishes and processed foodstuffs among the imported foods. (4) The frequency of instant foods for the carried lunches showed the meaningful relation with frequency of use of imported foods. (5) In the view of use of instant foods for the lunches, the group of people who carried the lunches 3 or 5 times per week used the imported meat foods, the other group who carried the lunches 1 or 2 times per week marked the high frequency of having coffee and tea.

Contributions of specific foods to absolute intake and between-person variance in 13 nutrients were examined to develop a short food frequency questionnaire (FFQ) for the Korean elderly using dietary data collected by a semiquantitative FFQ with 96 food items. The contributions of specific foods to 90% absolute nutrient intake were measured by assessing their percentage to the total consumption of a nutrient by our samples(n=98). To assess the contribution of the foods to the between-person variance in intake of each specific nutrient, stepwise multiple regression was performed. Cumulative R2 served as the measure of contribution to variation in intake. The most important food source of absolute intake was rice for energy and protein. Important foods of between person variance contribution include bread for energy and pork for protein. Important foods of absolute and variance contribution of nutrient intake were similar for fat(noodles including jajangmyun and kalguksu), calcium(anchovy and milk) and vitamin A (carrot). The number of foods necessary to account for the variation in nutrient intake among older people in Korea differ considerably by nutrient: 18 - 43 and 8-26 foods were accounted for the respective 90 and 80% of absolute intake depending on nutrients. Carbohydrates and vitamin A and C had relatively a few major sources, thus may be assessed well by a small number of foods. Conversely, iron, potassium and B vitamins appear to need longer lists of foods. Fewer numbeer (6 - 12 and 4 - 9) of foods were required for the corresponding percentages of between-person variation for all nutrients. Depending on nutrients, 0.980-0.995 and 0.924-0.987 were respective correlation coefficients of nutrient intakes measured by 96 food items with those by lists of foods for 90% and 80% of absolute intake contribution. These findings suggest that an incomplete food list on the basis of its contribution to absolute and between person variation intakes may still be effective in discriminating among individuals. The results of this study may be useful in the design and use of dietary questionnaire.

Currently, dietary life in Korea is rapidly changing. New food from other countries introduced to the diet with changing economic and social environment. The number of meals away from home is increasing. Also, number of students who served by the school food service are increasing. In this paper, the menu in the school food service are compared between 1995 and 2001. Analysis was done to see changes in the use of Korean traditional foods. Between July, 2001 and August, 2001, by mail 103 schools were surveyed to analyzed menu. Menu from 2001 survey are compared with menu from 1995 survey. The results are following; 1) New menus are introduced in 2001 compared with 1995. 2) The number of menu using animal foods are increasing in 2001. 3) Among cooking methods, stir frying, and deep frying, are used more in 2001 than that of 1995. 4) The number of Korean dish served are decreased in 2001. 5) Students favorite dish are changed. Students like dishes cooked with deep frying method and western foods. With these results, menu of school food services become more westernized and using more frying methods because of students' taste preference. These trend are not recommendable for the students health, because it is known that Korean traditional dishes are more healthful. There should be more research and effort to keep Korean tranditional foods in the menu of the school food service for students health.

This study was carried out to examine dietary habits, food frequency and dietary attitudes by gender and nutrition knowledge level in upper-grade school children. Subjects were 223 boys and 208 girls attending 13 elementary schools (5 th and 6 th graders). A self-administered questionnaire was developed to assess nutrition knowledge, dietary habits, food frequency, and dietary attitudes. Nutrition knowledge score assessed by 19 questions was significantly higher in girls than in boys. There were significant differences between boys and girls in several items in dietary habits such as enough breakfast time, dinner regularity, number of side dishes, eating speed, type of snack after dinner, and degree of saltiness of dishes. Girls consumed staple foods such as rice, noodles or bread more frequently, and consumed less frequently ramyun, fried foods, fast foods, and Chinese foods than boys. In addition, girls had more positive dietary attitudes in trying to reduce fast foods, Chinese foods, ramyun and fried foods. Also children in the high or moderate nutrition knowledge level groups had better dietary habits in frequency of meals, frequency of breakfast, enough breakfast time, dinner regularity, activity during the meal, number of side dishes, eating speed, type of snack after dinner, and better food choices by eating staple foods and vegetable side dishes, meats and beans more frequently, and fried foods, doughnuts/cakes, Chinese foods less frequently, and had better dietary attitudes in breakfast, vegetables and fruit intake than children in the low nutrition knowledge level group. Our results showed that dietary habits, food frequency and dietary attitudes were different by gender and nutrition knowledge level. These results suggest that in developing nutrition education program for elementary school children, the differences between gender and nutrition knowledge level should be considered. Nutrition education in elementary schools may change dietary habits and dietary attitudes through increasing nutrition knowledge.

Dryfilm method by using 3M Petrifilm$^{TM}$ has been examined to replace conventional agar method for isolation of microorganisms from foods. The objectives of the present study were to evaluate suitability of dryfilm method as a microbial isolation method and to determine the effect of antimicrobial agent on dryfilm for isolation of microorganisms from foods. Five different foods, milk, ground beef, fishery surimi, Takju and wheat flour were used to isolate the natural microflora in foods and the inoculated Escheri chia coli. Standard method agar (SMA, Difco) and Petrifilm$^{TM}$ aerobic count (PAC, 3M) were used to isolate total microorganisms from foods. Violet red bile agar (VRBA), brilliant green lactose bile (BGLB) broth and Petrifilm$^{TM}$ coliform count (PCC, 3M) were used to isolate coliforms from foods. E. coli broth (EC broth) and Petrifilm$^{TM}$ E. coli count (PEC, 3M) were used to isolate E. coli from foods. Acidified potato dextrose agar (APDA) and Petrifilm$^{TM}$ yeast & mold count (PYMC, 3M) were used to isolate yeasts and molds from foods. Total aerobic plate counts isolated from five different foods by SMA and PAC (3M) were riot significantly different each other at P<0.05 level and were highly correlated each other ($\geq$0.96). Mugwort extract as an antimicrobial agent did not affect microbial enumeratiion of Dryfilm. Significantly higher number of coliform colonies were formed on VRBA than PCC (3M) from ground beef, but they were not significantly different in coliform colonies from milk samples. PCC (3M) and BGLB were not significantly different for enumeration of coliforms in milk and beef samples. Significantly higher number of E. coli were isolated by EC broth than PEC from ground beef, but these were not significontly different for enumeration of E. coli from milk. Yeast and mold counts isolated from Takju and wheat flour by APDA and PYMC (3M) were not significantly different at P<0.05 level. These data indicate that dryfilm method by using 3M Petrifilm$^{TM}$ can be successively used as an alternative to conventional agar method for enumeration of microorganisms in various foods.

The purposes of this study were to assess the perception of the characteristics of Condonopsis lanceolata dishes and to find out the development need & willingness to purchase for Condonopsis lanceolata dishes in view of industrial foodservice dieticians. Of 250 questionnaires distributed, 152 completed questionnaires were used for the statistical evaluation. Statistical data analysis was using SPSS 10.0 program for descriptive analysis, $X^{2}$-test, t-test and analysis of variance. The perception score on the characteristics of Condonopsis lanceolata dishes varied according to the number of meals served, mean price of a meal, type of food service management, food cost variation, offering type, and intake frequency; however, perception score was not affected by the number of meal serving/day and the type of menu. Regarding processed foods containing Condonopsis lanceolat, the need for developing side dishes was the highest in processed foods using Condonopsis lanceolata, followed by alcoholic beverage, one dish foods, health foods, and desserts. The score for willingness to purchase dessert of Condonopsis lanceolata was the highest, followed by alcoholic beverage, one dish foods, health foods, and side dishes.
