Dietary behavior of the elerly over 65 and local products in Yeongi Chungnam were studied during busy farming season and meal menu was developed based upon the information surveyed. In allowance, 45% of them lived with less then one hundred thousand won but 95% had their own residence(P<0.001). The dental health conditions of the male and female elderly did not show significant differences but had tendencies of bad conditions with 68% and 80%, respectively. Percentage of using denture at least one side was only 48%(P<0.05). Meal preparation was mostly done by 75% of the female elderly and only 64% of the elderly in the area took meals regularly. Recommended intakes(RIs) of calorie, protein, dietary fiber, calcium for the elderly were significantly very low(P<0.001), but those of sodium were high(P<0.05). Meal menu was developed for the meal service introduction in the pavilion of the elderly with considerations of the food habits, nutritional status, and local products studied.

Two experiments were conducted to determine the effect of feeding levels on intake and nutrient utilization of oat (Avena sativa) hay (OH) by goats and potential feeding value of leftovers from high levels of offer in sheep. In experiment 1, the goats (15) were offered OH at three levels of feeding to give leftovers of about 20% (T-1), 35% (T-2) and 50% (T-3) of DM offered. A marked effect of refusal rate of OH on intake and digestibility of nutrients was evident. Allowing selective consumption at higher levels (T-2 and T-3), the intake of DCP and TDN from OH was found not only to meet the maintenance requirement but provided surplus nutrients for moderate production. In experiment 2, Sheep (3) were offered one of the three dietary treatments viz OH, refusals left uneaten by goats in T-2 and T-3 (OHR) and 3% urea treated oat hay refusals (UTR) in a $3{\times}3$ latin square design. Though the potential feeding value of leftovers (OHR and UTR) was lower than OH, the results confirm the possibility of their effective use. It was concluded that feeding above the conventional ad libitum level could be an alternative to improve the performance of ruminants fed feeds like oat hay. The potential impact of the strategy would, however, depend on the effective reutilization of leftovers for feeding other animals.

This study was to investigate consumer recognition on food label of food package. The results of this study were as follows: 1. when shopping for food, the items considered the most were taste of family, food safety, nutrition and price, respectively. 2. 95.5% of respondents confirmed of the food label of food package when shopping for food. The items confirmed the most on food label were expiration date, manufacture date, manufacturer, food additives and nutrition, respectively. 3. 85.3% of respondents did not satisfy on the food label of food label of food package. 43.6% of respondents demanded food additives more detailed. 28.2% of respondents demanded nutrition information more detailed. 28.2% of respondents demanded food function more detailed. 4. The food which respondents satisfied on food label most were snack '||'&'||' cookies, nuddle, spices, can '||'&'||' bottled food, instant food, processed meat foo, frozen food and imported food, respectively. 5. The group with the most hphrases falling in the top rank was nutrition/calories. The phrases in the nutrition/calories group scored in the top rank were 3 "positive" nutritional characteristics(addition of vitamins, addition of DHA, high dietary fiber) and 5 "nagative" nutritional characteristics(no sugar, low sugar, low calories, low salt and low cholesterol). The group with the most phrases falling in the third rank was ingredient. The phrases in the ingredient scored in the third rank were add of food additives. 6. 55.5% of respondents did not know Recommended Daily Allowance(RDA) information and 61.9% of respondents did not understand the nutrition declaration(content) of food package but 65.7% of resspondents understood the nutrition claim of food package.

The purpose of this study was to investigate the levels of recognition, practice and information acquisition behaviors regarding food additives of university students for development of educational programs. The data were collected from 283 students in the Yeungnam region through a self-administered questionnaire. The level of concern about food additives was intermediate. The level of checking labels for food additives when buying processed foods was not high. The main reason for not checking labels for food additives was "Buying the special brand products repeatedly". In the factor analysis for perception of food additives, three factors were categorized; effect of food additives on human health, administration and regulation of food additives, and necessity of food additives. According to regression analyses, grade, concern about food additives and perception of amount of food additives had significant effects on human health. The significant variables for administration and regulation of food additives were gender, grade, major, monthly allowance and concern about food additives. In addition, major was a significant variable for the necessity of food additives. Many respondents did not reduce intake of food additives; males did less than females. Most respondents answered they did not acquire sufficient information about food additives. Regarding needs for information content on food additives, respondents wanted information about safety of food additives the most, followed by items of labels for food additives, and ways to reduce intake of food additives.

This study was to investigate the sorbic acid, benzoic acid and sulfur dioxide in commonly consumed beverages, snacks and instant ramens in Korea. A total of 150 food samples including 50 beverages, 50 snacks and 50 instant ramens were examined using the Korea Food Code method. Sorbic and benzoic acid were analyzed by the HPLC method, whereas sulfur dioxide was measured by Monnier-Williams method. Our results indicated that benzoic acid was detected in six beverages samples, and its concentration was in the range of 3.08-11.94 mg/kg. The contents of both sorbic and benzoic acid in 50 beverage samples did not exceed the residue allowance standards set by the Ministry of Food and Drug Safety (MFDS). Sulfur dioxide was detected in 12 beverages samples, but its content was lower than the detection limit specified in the method by the Korea Food Code. On the other hand, sorbic acid was not detected all samples. These results provide a basic data regarding sorbic acid, benzoic acid and sulfur dioxide in commonly consumed beverages, snacks and instant ramens in Korea.

Dietitians in various fields have used food exchange lists for food preparations. However it seems that the present food exchange lists are complicated, thus they cause many problems for dietitians to use in the fields. Therefore this study evaluated to the extent of awareness and utilizations of KDA food exchange lists in dietitians and also collected dietitian's opinions for revising food exchange lists such as serving size, serving calories, and for unifying food guidelines and dietary and dietary guidelines for Korean to one simple guideline. 192 dietitians who presently work in urban and rural areas were recruited and data based on survey were collected. As results, most of dietitians(87.5%) knew well about food exchange lists, but only 7.8% of them always would use food exchange lists for menu planning, 56.3% of dietitians did not use it at all and 34.4% occasionally use it. And 88.0% of dietitians wanted to revise food exchange lists totally or partially, 69.8% of dietitians hoped to amend various calories per one serving in food exchange lists to one serving calorie. The desirable on serving calorie was selected as 100kcal(51%) or 50kcal(38%) by dietitians. The dietitians in this study understood very well dietary guidelines(86.5%) and food guidelines(88.5%) for Korean, and 66.1% dietitians wanted to unify both guidelines. In case of unification of guidelines, dietitians answered that 7-8 items(30%) or 5-6 items(27%) should be included in guideline. In the question about reference value for daily allowance, most dietitians(56%) satisfied with the present various reference values for various generation while 28% of dietitians wanted to change to have one reference value (standard with 2000kcal, adult female). This study will provide basic informations for revising or adjustment of food exchange list and dietary or food guidelines for Korean.

The daily intake of dietary fiber by Korean population in urban and rural areas was computed from an optimized food intake based on national nutrition survey, food balance sheet, and the dietary fiber content of Korean foods. The average intake of dietary fiber the nationwide and in urban and rural areas were 24, 22 and 28g in the 1970's, 20, 21 and 20g in 1980's , and 22, 22 and 21g in the 1990's , respectively. As compared with the recommended dietary allowance of 20-25g for Koreans, the average intake of dietary fiber was within the normal range, regardless of urban and rural areas. Since the dietary pattern of korean people is being changed according to different life style, the exact intakes of dietary fiber by diverse specific population groups should be assessed in the future.

The nutritional value of Korean traditional diet was estimated by using the 7-dish meal of Kim Ho Jik (1944) and the standard weekly menu of Bang Sin Young (1957), and compared to the current Recommended Daily Allowance of Korean. The Korean traditional diets were estimated to be able to supply 2,000-2,500 Kcal and 80-90g of protein per day. The constitution of energy was made by 73-77% carbohydrate, 15-18% protein and 10-12% lipid. The content of animal protein was 20-30% of total protein. The Korean traditional diet could supply sufficient amounts of protein, minerals and vitamins for an adult male, if the energy intake exceeds 2,00 Kcal per day.
