We conducted a survey on Japanese women's consciousness of food culture and their traditional food consumption by self filling-out questionnaire during January, 2000 for the period of a month, For the survey we selected 250 women residing in Kyoto, Japan. For the statistic work we used SAS package system, and t-test, $\cal{X}^2-test$ and Duncan's multiple range test were also used to verify the results significance. The purpose of this survey lies in gathering a basic data on the comparative direction of Korean and Japanese women's food culture in the future 1. Comparing the preferred food purchase place, In case of Korean women, traditional market was comparatively more preferred while Japanese women relatively preferred convenience store (p<0.001). 2. In case of Japanese women, they answered there is no difference from ordinary days on New Year's Day (71%) and Christmas (40%) while 38% answered they prepare food at home. 40% said they prepare food on parents-in-law's birthday, and 41% said no difference from ordinary days. 52% said they prepare food at home on husband's birthday. For their own birthday, 32% said yes to preparing food at home while 45% said no difference and 22.3% said eating out. For children's birthday 65% said preparing at home, 16.3% said no difference and 14.9% said eating out. 3. Comparing the conception on traditional food, Korean women answered 'complicated' (77%) most while 'simple' (5%) least, which indicates their demands for simplified recipes. In case of Japanese women, 'complicated' (44%) was most while 'scientific' (6%) was least which indicates their demands for scientific way of recipes. There were differences shown by age (p<0.001) and the older the more said 'simple' or 'logical' (p<0.01). 4. As the reason for the complicity of traditional food recipes, Koreans said 'too many hand skill' (60%) most while 'too many spices' (8%) least. For Japanese, 'various kind of the recipe' (55%) was most while 'too many hand skill' (7%) was least. There were significant differences shown by academic background (p<0.01) and income(p<0.01), and the lower the academic background, the more said 'too many spices' as the reason for the complicity in making traditional food. Generally, the lesser the income, the more tendency to say 'various kinds of the recipe'. 5. In case of Koreans, 'the recipe is difficult' (56%) was high while 'uninterested' (9%) was low in answer which showed differences by academic background (p<0.05), and in case of Japanese, 'no time to cook' (44%) was high while 'uninterested' (7%) was low. 6. The following is the reasons for choosing traditional food as a snack for children. In case of Koreans, they answered as 'traditional food' (34%), 'made from nutrious and quality materials' (27%), 'for education' (22%) and 'suites their taste' (17%) revealing 'traditional food' is highest. In case of Japanese, it was revealed in the order of 'made from nutrious and quality materials' (36.3%), 'traditional food' (25.2%), 'suites their taste' (22.6%), 'for education' (12.8%) and 7. Comparing the most important thing for the popularization of traditional food in the world, Koreans answered 'taste and nutrition' (45%) most while 'shape and color' (6%) least. In case of Japanese, 'taste and nutrition' (75%) was answered most while 'hygienic packaging' (4%) was least. Both considered 'taste and nutrition' as most important thing for the popularization of traditional food in the world. 8. In case of Koreans, they answered they learn how to make traditional food 'from mother' (47%), 'media' (18%), 'school' (15%), 'from mother-in-law' (14%), 'private cooking school' (4%) and 'close acquaintances' (2%). In case of Japanese, they said mostly learn 'from mother', but it was also shown that the lower the academic background the lesser the tendency of learning 'from mother' but 'from school' (p<0.001). 9. About the consumption of traditional fermented food, Koreans said they make kimchi (90%), pickled vegetables (39%), soy sauce (33%), bean paste (38%), salted fishery (12%) and traditional liquors (14%) at home while 67% for salted fishery and 48% for traditional liquors answered they buy rather than making at home. On the other hand, Japanese answered they mostly buy kimchi (60%), soy sauce (96%), bean paste(91%), natto(92%), salt fermented fish foods (77%) and traditional alcoholic beverage (88%) to eat. This difference was shown very distinct between Korean and Japanese women (p<0.001). 10. About the most important thing in food, Koreans answered in the order of 'liking and satisfaction' (33%), 'for health' (32%), 'for relieve hunger' (18%) and 'convenience' (17%). In case of Japanese, it was revealed in the order of 'for health' (61%), 'liking and satisfaction' (20%), 'to relieve hunger' (16%) and 'convenience' (3%). This shows that Japanese women take comparably more importance to health than Korean women. The conception of food was shown different between Korean and Japanese women (p<0.001), and Koreans showed level 4-5 of food culture while Japanese showed level 5.

인쇄형 TTI의 잉크로 천연물질인 안토시아닌의 적용 가능성을 확인하기 위해 실제 인쇄형 TTI를 제작하여 색 변화를 확인하였다. 안토시아닌은 반응속도가 느려 TTI에 적용이 어렵다. 이를 해결하기 위해 ${\beta}$-글루코시다아제를 이용하여 안토시아닌의 탈당화를 유도하여 보다 불안정한 안토시아니딘 잉크를 제작하였다. 그리고 인쇄형 TTI로 제작이 적합한지 확인하기 위해 인쇄적성을 확인하고 적용가능한 식품군을 탐색하였다. 실험결과, 인쇄적성의 경우, 틱소트로피의 히스테리시스 성질을 나타내어 인쇄적성이 적합한 것으로 확인되었다. 색 변화의 경우, 같은 온도와 pH 조건 하에서 안토시아닌 TTI의 색 변화 속도보다 안토시아니딘 TTI의 색 변화속도가 빠른 것을 확인할 수 있었다. 또한, 안토시아닌 인쇄형 TTI의 활성화 에너지는 65.21 kJ/mol, 안토시아니딘 인쇄형 TTI의 활성화 에너지는 86.92 kJ/mol로 확인되었다. 이는 ${\beta}$-글루코시다아제를 처리한 안토시아닌의 탈당화가 안토시아닌의 반응속도를 빠르게 할 뿐만 아니라, 활성화 에너지도 증가시킨 것으로 사료된다. TTI의 활성화 에너지와 식품의 활성화 에너지를 비교한 결과, 안토시아닌 TTI는 냉장 육제품에 한정적으로 적용 가능하였다. 반면에 안토시아니딘 TTI는 냉장 육제품과 냉장 어류에 적용 가능하였다. 하지만, 안토시아닌 TTI는 색 변화 종말점에 도달하는 시간이 길기 때문에 냉장 육제품에 적용이 어려울 것으로 사료된다. 반면 안토시아니딘 TTI의 경우, 색 변화 종말점에 도달하는 시간이 짧기 때문에 냉장 육제품과 냉장 어류에 적용이 가능할 것으로 사료된다.

In this study, 419 students of the 6th grade in three schools in Masan were surveyed. The students having less than 24 items among 48 protein-rich foods easily obtained were considered as unbalanced-diet students. Their general circumstances, character, status of growth and development and school performance were compared with those of balanced-diet students. The results were following. 1. The actual condition of unbalanced diets of protein-rich food 1) Female showed high degree of unbalanced diet in meat food while male in shell-food. Both sexes liked processed food stuffs such as ham, sausage and boiled fish paste but not salted. Both of them disliked beans. 2) The reason for unbalanced diet, they answered, was bad taste and smell of some foods. The reason, their mothers amswered, was they fed their children some particualr foods. 3) The attitudes of the mothers against unbalanced diets were coaxing their children to eat some foods for they are good for health or forcing their children to eat some foods. The most effective method on the children was coaxing and the next was changing cuisines. 2. The general circumstances of the students. 1) 168 students (male: 85, female:83) among 419 students who were studied were unbalanced-diet students and the extent of unbalanced diet was similar in both sexes. 2) The rate of unbalanced-diet students was higher among the students who were the first child in the family, had a small family or were fed milk or mixed milk. 3) The school career of unbalanced-diet student's mothers was higher and the rate of unbalanced-diet students was higher among the students who have rich families or career mothers. 3. The status of physical condition 1) The height and weight of unbalanced-diet students were lower than those of the standard of Korean children. The status of balanced-diet students were better than that of the standard. 4. Degree of school performance 1) The school records of unbalanced-diet students was 81.4 points in average, which was 1.3 points lower than the average of city students and that of balanced-diet students was 2.8 points higher than average. There was a significant gap between the two groups. 5. The relation between unbalanced diet and character 1) Compared balanced-diet students, unbalanced-diet students showed high degree of nervousness and coldheartedness and low degree of self-reliance and self-possession. There was a significant gap between the two groups and it showed that unbalanced diets affected the formation of character.

Objectives: The purpose of this study was to assess energy and nutritional intake and investigate the preference for food and cooking methods of the residents in elderly care facilities. Methods: Data were collected from 72 residents (10 males and 62 females) aged ${\geq}70$ years in elderly care facilities using questionnaires, food photographs for estimating dietary intake and records for daily physical activity. Results: Average age of the study participants was 85.0 years and 41, 36 and 8 had dementia, hypertension and diabetes mellitus, respectively. 15%, 65% and 19% of subjects were physically mobile, enervated, and immobile, respectively. Daily energy intake was 1360.2 kcal in men and 1378.0 kcal in women, which were 68.0% and 86.1% of the estimated energy requirement (EER) of dietary reference intake for Koreans (KDRI) for ${\geq}75$ year old individuals, respectively. Estimated energy expenditure (EEE) of subjects calculated using formula from KDRI was 1361.9 kcal and EER calculated using estimated daily physical activity (EDPA) was 1232.9 kcal. Energy intake and EEE from KDRI were higher than EER from EDPA. Dietary intake of dietary fiber, calcium, potassium, zinc, vitamin $B_2$, niacin, vitamin C were lower, and protein, phosphorous, iron, sodium, vitamin A, vitamin $B_1$, vitamin $B_6$, vitamin E were higher than the corresponding ones of KDRI. Subjects liked meats, fishes and shellfish, and fruits, while subjects disliked milk, seaweeds and salted fish and salted vegetables. Cooked rice, soybean paste soup, beef, cooked sliced radish strip, and yogurt were favorite foods, with steam being a favorite cooking method. Subjects considered nutrition as the most important factor for improving food service quality. Conclusions: Results of this study could be utilized for improving food-service for the residents in elderly care facilities, and provide a basis for setting reference intake of energy and nutrients of the elderly having very low activity levels.

As a part of the investigation for utilizing pearl oyster by-products, a rapid salt-fermented pearl oyster using commercial enzyme was prepared and also examined on the characteristics. The salt-fermented pearl oyster prepared by optimal condition, which was prepared by mixing of minced pearl oyster, 15% salt, and 1% $Protamex^\circledR$ and fermented for 4 weeks, was superior in hydrolysis degree (28.7%) and ACE inhibitory activity (92.6%) to salt-fermented pearl oyster prepared by other conditions, such as the use of whole tissue, different enzymes $(Alcalase^\circledR,\;Neutrase^\circledR\;and\;Flavourzyme^\circledR)$, different salt concentrations (20 and 25%), and different fermentation periods (2, 6 and 8 weeks). There were, however, some shortcomings with this product. It showed a dark green color and an unfavorable bitter taste. These shortcomings were improved by the addition of seasoning paste. The calcium and phosphorus contents of the seasoned salt-fermented pearl oyster were 64.2 mg/100 g and 71.6 mg/100 g, respectively, and the calcium content based on phosphorus was a good ratio for absorbing calcium. The total amino acid content of the seasoned and salt-fermented pearl oyster was 7,054 mg/100 g and the major amino acids ware aspartic acid (555.1 mg/100 g), glutamic acid (1,131.2 mg/100 g), alanine (658.2 mg/100 g), and lysine (695.5 mg/100 g). The seasoned salt-fermented pearl oyster, along with angiotensin I converting enzyme (ACE) inhibitory activity (98.3%), also showed a recognizable level (87.5%) of anti-oxidative activity.

The purpose of this study was to investigate the dietary habits, the nutritional knowledge and the consumption patterns of convenience foods of 618 university students located in the Gwangju area, from November twentieth to November thirtieth, 2002. The subjects included 301 males (48.7%) and 317 females (51.3%). This survey was conducted using a self-administered questionnaire. The percentage of students who were underweight, normal and overweight based on their body mass index (BMI) was 3.7, 88.0 and 8.3 far the males, and 29, 71 and 0 for the females, respectively. Most students (73.8%) skipped breakfast. This was because of lack of time (65.1%) of the cases. Self-reported eating habit problems were eating irregular meal (52.4%), overeating (21%), prejudiced meal (12.4%) and skipping meal (7.4%). The type of favorite snack was biscuit (31.9%) and cup Ramyon (31.9%). The rates of alcohol drinking in male and female students were 88.0% and 85.8% respectively, and the rates of smoking were 35.9% and 28% respectively. Males ate fiequently cup Ramyon (2.08 $\pm$ 2.95), fries (pork cutlet, fried potato) (1.91 $\pm$ 2.58), Ramyon (1.81 $\pm$ 3.00) and kimbab (1.70 $\pm$ 3.17) more frequently, while females ate kimbab (2.25 $\pm$ 3.26), cup Ramyon (1.89 $\pm$ 2.09), fries (pork cutlet, fried potato) (1.77 $\pm$ 2.67), Ramyon (1.46 $\pm$ 1.1.95) and fish paste (1.45 $\pm$ 2.22) more frequently. The nutritional knowledge score was higher in females than in males. The mean consumption patterns of convenience foods of students living in home were lower than that of students living in dormitory and boarding w/cooking. When the amount of pocket money available and the body mass index increased and the nutritional knowledge level was low, the mean consumption of convenience foods increased. The mean consumption of convenience foods correlated negatively with nutritional knowledge (p < 0.01). Therefore, nutritional education for university students is needed so as to improve their health and nutritional education program should be developed to meet the various needs of these students.
