Numerous studies suggest that the effects of lactic acid bacteria (LAB) on oxidative stress in vivo are correlated with their antioxidative activities in vitro; however, the relationship is still unclear and contradictory. The antioxidative activities of 27 Lactobacillus plantarum strains isolated from fermented foods were determined in terms of 2,2-diphenyl-1-picrylhydrazyl, hydroxyl radical, and superoxide radical scavenging abilities, reducing activity, resistance to hydrogen peroxide, and ferrous chelating ability in vitro. Two fuzzy synthetic evaluation models, one with an analytic hierarchy process and one using entropy weight, were then used to evaluate the overall antioxidative abilities of these L. plantarum strains. Although there was some difference between the two models, the highest scoring strain (CCFM10), the middle scoring strain (CCFM242), and the lowest scoring strain (RS15-3) were obtained with both models. Examination of the antioxidative abilities of these three strains in $\text\tiny{D}$-galactose-induced oxidative stress mice demonstrated that their overall antioxidative abilities in vitro could reveal the abilities to alleviate oxidative stress in vivo. The current study suggests that assessment of overall antioxidative abilities with fuzzy synthetic models can guide the evaluation of probiotic antioxidants. It might be a more quick and effective method to evaluate the overall antioxidative abilities of LAB.

The high caffeine intake by adolescents has been a concern. The purpose of this study was to examine the awareness and consumption of caffeine-containing foods among 443 high school students using a questionnaire. An analysis of the spending patterns of the students' weekly allowance showed that the amounts spent on purchasing caffeine-containing foods were higher for female students than male students (P <0.001). The scoring of the perception of caffeine was 3.1 out of 5, interest in the caffeine content of food was 2.6, consumption of caffeine-containing foods was 2.6, and usefulness of caffeine-containing foods was 2.7. The awareness of caffeine content in food was significantly higher in females (7.3 out of 11) than male students (6.7) (P<0.01). Approximately 59% of students perceived that the relationship between caffeine-containing foods and health, was harmful, and the experience of side effects after taking caffeine was significantly higher in female students than males. These side effects include heartburn (P<0.001), headache or dizziness (P<0.001), irregular heartbeat (P<0.05), and hands and feet shake (P<0.01). Caffeine-containing foods were purchased at convenience stores (62.1%). The factor considered when purchasing caffeine-containing foods was taste (72.2%), and the use of nutrition labeling for caffeine-containing foods scored 2.0 out of 5 points. When assessing the intake of caffeine-containing foods, the foods consumed more than once a week were in the order of coke, chocolate, chocolate milk, chocolate pie, and chocolate bars. These results suggest that it is necessary to prepare a caffeine-related nutrition guide improvement by sales management, and strengthen food labeling standards for the desirable recognition of caffeine and its safe intake by adolescents.

Food consumption pattern between Korea and Japan were compared on the basis of the data from the National Nutrition survey which has been carried out annually in Korea (1969-1988) and in Japan (1950-1988) for the guide of the future food and nutrition policy. Total food intake has been decreased in Japan since 1973. In spite of fluctation of total food intake, there was an increase of food consumption in Korea. The intake of animal food has been increased, while that of vegetable food decreased, in both countries. Proportion of the total food intake from animal sources of Japanese in 1988, 25.3%, was greater than that of Koreans, 20%. The intakes of cereal and grain products have been decreased in both countries, but the amount of these food groups consumed by Koreans was 70 to 80g more than that by Japanese in 1988. When the animal food intake was compared, intakes of meats, fishes, shellfish and eggs have been increased considerably in Korea. Intakes of milk and milk products and meat have been increased, while those of fishes, shellfishes and eggs kept an even level since 1975, in Japan. According to changes of the national standards of height and weight in both countries, the average height has been increased greatly from 1970 to 1980 in Korea, and the tendency was the same for the average weight.

1. Background of the Study Old Testament time made some food and Sauces. Cosher food is God's Covernant. Ancient Greek cooking and Roman cooking had been Sauces. Much of what we know of Greek gastronomy is found in the writting of Archestrate, cooking is sigle and direct, Sauces are Cumin, Vinegar, Roman culinary comes from mareus, first century A.D. many of the ingredients used in apicius's recipes are seen againg in midival Eurpean cooking. ① Cumin Sauce for Oyster ② Sauce for grounds, puree, and cardoons. 2. Culinary in the Middle ages Liaquid Flavorings their Sauces tested Verjuice and Vinegar are most often called for when a Liquid is needed, Spices and Liaisons. 3. Cookery the eighteenth century The eighteen the century brought about greated Systemization of basics, coulis, Jus, and bouillons. 4. The twentieth century culinary Careme were Systematized and recorded by Auguste Escoffier in his Guide Culinare Standardized. 5. Grand Sauces are Considered one of the greatest test of a Chef's Skill, Whether they are classics, Such as Sauce, Supreme, demand the highest technical expertise. The Successful paring of Sauce with a good demonstrates an understanding of the food and an ability to judge. Sauce making allows the cook more freedom to work flavors, textures, Aromatics, Tasty, and color than any other area of cooking. A Sauce is never eaten alone, function, balance, the direct flavor, Sauces presents the basic Sauce-making techniques that have been used in the past and that are popular today, Sauces are organized around the primeifhes of classic world cooking 6. Grand Sauces are 1) Brown Sauces are 1) Brown Sauce ① Demiglace ②Espagnole ③ Fond de veau 2) Bechamel Sauce 3) Velote Sauce 4) Tomato Sauce and 5) Hollandaise Sauce ① Brown Sauce made with Stock, Roux, Tomato Paste and Mirepoix. ② Bechamel Sauce made with Roux and Milk. ③ Veloute Sauce made with Roux and White Stock. ④ Tomato Sauce made with Tomto, Vegetable and Stock. ⑤ Hollandaise Sauce made with Egg and Butter.

We analyze the HACCP Prerequisites of National Veterinary Research and Quarantine Service (NVRQS), Korea Food and Drug Administration(KFDA), and US Food Safety and Inspection Service (FSIS) and recommend contents and ranges to be complemented and used for the preparation of guidelines. We used the HACCP Notice of the Processing Livestock Act, the HACCP Application Manual for Livestock Processing Plants, the HACCP Notice of the Food Sanitation Act, US GPO 9 CFR and 21 CFR, US FSIS Directive 11,000.1, and HACCP-based Inspection reference guide of Consumer Services, North Carolina Department of Agriculture. The Prerequisites of NVRQS and KFDA are composed of 66 and 84 items respectively, without detailed guidelines for their application. This may decisively affect the application in the field and the evaluation activities. Water supplies, washing and disinfection monitoring tools, and examining and correcting plan are required to be improved. If the standards of compliance of each Prerequisite item as well as performance guidelines are given, the application and evaluation will be performed more effectively. The evaluation items should be associated with Prerequisite operations such as non-compliance complement, self-evaluation, and record keeping. Hazards found during official inspection should be promptly controlled not to contaminate the work places and processing items. As the HACCP is expected to spread from farms to tables, the standardized Prerequisite program among the official governments should be prepared.

To understand the formation of initial gut microbiota, three initial fecal samples were collected from two groups of two breast milk-fed (BM1) and seven formula milk-fed (FM1) infants, and the compositional changes in gut microbiota were determined using metagenomics. Compositional change analysis during week one showed that Bifidobacterium increased from the first to the third fecal samples in the BM1 group (1.3% to 35.1%), while Klebsiella and Serratia were detected in the third fecal sample of the FM1 group (4.4% and 34.2%, respectively), suggesting the beneficial effect of breast milk intake. To further understand the compositional changes during progression from infancy to childhood (i.e., from three weeks to five years of age), additional fecal samples were collected from four groups of two breast milk-fed infants (BM2), one formula milk-fed toddler (FM2), three weaning food-fed toddlers (WF), and three solid food-fed children (SF). Subsequent compositional change analysis and principal coordinates analysis (PCoA) revealed that the composition of the gut microbiota changed from an infant-like composition to an adult-like one in conjunction with dietary changes. Interestingly, overall gut microbiota composition analyses during the period of progression from infancy to childhood suggested increasing complexity of gut microbiota as well as emergence of a new species of bacteria capable of digesting complex carbohydrates in WF and SF groups, substantiating that diet type is a key factor in determining the composition of gut microbiota. Consequently, this study may be useful as a guide to understanding the development of initial gut microbiota based on diet.

Objectives: Study purpose was to investigate perception on diet, diet problems and related factors among young adult women using focus group interviews (FGI) based on the Social Cognitive Theory (SCT). Methods: Eight groups of FGI were conducted with 47 female undergraduate or graduate students. Guide for FGI included questions regarding perception on optimal diet, diet problems and cognitive, behavioral, and environmental factors of SCT. FGI were video, audio-taped, transcribed and analyzed by themes and sub-themes. Results: Subjects showed irregular eating habits (skipping breakfast, irregular meal time) and selection of unhealthy foods as the main diet problems. Regarding cognitive factors related to optimal diet, subjects mentioned positive outcome expectations (e.g., health promotion, skin health, improvement in eating habits, etc.) and negative outcome expectations (e.g., annoying, hungry, expensive, taste). Factors that promoted optimal diet were mainly received from information from mobile or internet and access to menu or recipes. Factors that prevented optimal diet included influence from friends, lack of time and cooking skills. Behavioral factors for optimal diet included behavioral capability regarding snacks, healthy eating and smart food selection. Subjects mentioned mass media (mobile, internet, TV) as the influential physical environment, and significant others (parents, friends, grandparents) as the influential social environment in optimal diet. For education topics, subjects wanted to learn about healthy meals, basic nutrition, disease and nutrition, and weight control. They wanted to learn those aspects by using mobile or internet, lectures (cooking classes), campaign and events. Conclusions: Study results might be used for planning education regarding optimal diet for young adult women. Education programs need to focus on increasing positive outcome expectations (e.g., health) and behavioral capability for healthy eating and food selection, reducing negative outcome expectations (e.g., cost, taste) and barriers, making supportive environments for optimal diet, and incorporating topics and methods found in this study.

The objective of this study was to develop nutrition education materials for older adults, 'nutritional management for healthy aging'. A booklet and four leaflets were developed based on lesson plans. Topics of the lesson plans included eating habit assessment. Korean food guide pyramid, meal planning, eating sensibly and weight management. The titles of the leaflets were 'Eating right for healthy aging', 'Eat calcium-rich foods', 'Enjoy fruits & vegetables' and 'Weight management'. Illustrations and icons appropriate to the texts were designed using illustrator 9.0 and Photoshop 6.0. Booklet (letter size, 5 chapters, 44 pages) and leaflets (B4 size, 6 sections) focused on modifying undesirable eating habits, providing practical tips for desirable behaviors, and behavioral modification such as recording in a food diary, goal setting and increasing self-efficacy. The drafts were pilot-tested by interviews with older adults(n=10), and minor changes were made. The characteristics of revised materials are as follows; i) materials focused on providing desirable eating behaviors for healthy aging, ii) messages were simple and specific, iii) large fonts(13 pt) were used and materials included interesting pictures and illustrations, iv) materials provided tips for balanced diets and recipes fur older adults, v) materials included sections for participation of learners including assessment of nutritional risk factors and obesity, meal planning and games. The revised materials are self-explanatory and can be used by older adults and in nutrition education for older adults.

Recently, the desire for low body weight, which is an abnormal weight construct along with obesity, has become an evident and serious problem in teenagers. In Korea, the desire for low weight is not perceived as an important problem, but it is rapidly expanding relative to the physical changes and developmental issues teenagers experience. The social atmosphere presented through mass media is the key influencer for the increasing low weight occurrence in teenagers. Because thoughts about beauty have changed among people, and since there is apparent blind interest in slim body shape and appearance, already low-weight individuals are attempting to lose weight along with obese persons. Thus, we consider it necessary to guide teenagers toward having correct perceptions with regard to weight and their own body shape, and that a healthy and appropriate weight is beautiful. Therefore, for this study, we investigated body perception, abnormal weight, attitude toward weight control, and factors related to eating behavior among teenage girls, who are considered the at risk group for overt body weight control behavior. Based on this, we have attempted to set in motion a systematic and active nutrition education program that will allow us to increase body satisfaction by educating on nutritional issues related to development, and ultimately, implant healthy body shape perceptions.
