This study aimed to identify a nutritionally vulnerable group and to examine their nutritional problems based on a relationship between socioeconomic position and nutritional status through life-course. A cross-sectional nationwide survey of 2005 Korean National Health and Nutrition Examination Survey (KNHANES) was used. A total of 8,930 participants aged $\geq$ 1 year were included. The socioeconomic position indicator was education level. Nutritional status was assessed by the percentage attainment of a dietary reference intake (DRI) and dietary quality based on nutrient intakes estimated by a 24 hour-recall data. Food insufficiency was examined by one-item food insufficiency questionnaire. The difference in nutritional status and food insufficiency according to educational level was tested by General Linear Model and Chi-square test, respectively. The nutritional status and food insufficiency was the worst during adolescence and older age than other period. Both quantity and quality of nutrient intakes was poorer in low education group than high education group. The prevalence of food insufficiency also was higher in low education group. The results were consistent across the life-course and sex. Based on these findings, we suggest that the development of various policy and strategies targeted to nutritionally vulnerable group is necessary to reduce nutritional inequality by socioeconomic position.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitudes, and food behavior of college students. The subjects of this study were 350 college students attending a university. The education group students received nutrition education three hours per week during a 4-week period offered in a 'Home Economics' course. A total of 150 students in the education group and 200 students in the non-education group completed pre-test questionaires examining nutrition knowledge, dietary attitudes, and food behaviors. Major findings were as follows : nutrition knowledge, and food behavior of the education group were improved compared to the non-education group. But significant changes were not observed in dietary attitudes in the education group. There were higher correlations between nutrition knowledge and dietary attitudes score, and between dietary attitudes and food behavior score at the posttest than those at the pretest. These results suggest that nutrition education for college students can effectively improve their nutrition knowledge and food behaviors.

The objective of tole study was to compare nutritional knowledge, attitudes and food practices of competitive athletes, recreational athletes and non-participants. All students enrolled at the University of Nebraska in an Introductory Nutrition course in which sports nutrition was stressed, were asked to participate in the study. The course was typical of many introductory nutrition courses ; about two thirds of the students were from the Department of Health, Physical Education and Recreation, and most of the students were encouraged to take this course by their advisers. The students were divided into three groups : 20 competitive athletes (mostly runners, swimmers, basketball players and football players for the University), 14 recreational athletes (who were involved in a planned exercise program at least 2 hours per week), and 19 non-participants. At the beginning of the semester, students completed a food frequency questionnaire, and a 24-hour food record based on the Food Guide Pyramid. A nutrition knowledge and attitude questionnaire was formulated specifically for this study, covering normal nutrition and sports nutrition. The results showed that consumption of foods from all Food Guide Pyramid food groups except the fats/oils/sweets group was not significantly different among the three student groups. Regarding the fats/oils/sweets group, competitive athletes consumed significantly more numbers of servings than recreational athletes, while the recreational athletes consumed significantly more than non-participants (p<0.01). The total mean scores from the nutrition attitude and knowledge questionnaire were not significantly different among the three student groups. However, combined athletes (competitive athletes and recreational athletes) obtained significantly higher scores on some of the nutrition attitude questions (p<0.05). The results of the study indicate that athletes, significantly lower scores on some of the nutrition knowledge questions (p<0.05). The results of the study indicate that athletes, whether competitive or some of the nutrition knowledge questions (p<0.05). The results of the study indicate that athletes, whether competitive or recreational, had a very positive attitude regarding the effects of nutrition on their sports performance and health: however, these athletes did not appear to apply scientific principles of sports nutrition to their diet. In conclusion, advising athletes to simply increase or decrease their intakes of certain foods is too simplistic an approach for maintenance of good health and for better sporting performance. Athletes and non-athletes need continuous nutrition education to help with improving their competitive edge and food choices.

Well-balanced meal is very important in its quantity and quality. Especially on the quantity field it becomes difficult for a foodservice operation to decide proper portion for individuals uniformly. These study was focused to setting up a proper portion by each food service operation. The results obtained were: 1. Individual consumption size from dormitory food service of college: cooked rice 282 g, soups 161 g, pot stewes 162 g, stir fries 53 g, stews 32 g, kimchies 47 g, fresh and boiled salads 43 g, one course dishies 477 g, pan broiles 44 g, meunieres 124 g. Individual consumption size from industry foodservice (white collar worker): cooked rices 228 g, soups 205 g, pot stewes 251 g, stir fries 20 g, stewes 76 g, kimchies 57 g, fresh and boiled salads 36 g, one course dishies 423 g, pan broiles 63 g, meunieres 38 g. 2. Proper portion of meal based on a statistical data is as follows: at college foodservice - cooked rices $280{\sim}290$ g, soups $155{\sim}170$ g, pot stewes 170 g, stir fries 60 g, stewes 35 g, kimchies $40{\sim}60$ g, fresh and boiled salads 50 g, one course dishies 480 g, pan broiles 50 g, meunieres 130 g and at industry foodservice (white collar worker) - cooked rices $220{\sim}250$ g, soups 210 g, pot stewes 250 g, stir fries 20 g, stewes 80 g, kimchies 60 g, fresh and boiled salads 40 g, one course dishies 430 g, pan broiles 70 g, meunieres 40 g.

The objectives of this study were to conduct preliminary research to investigate full course meals in Korean style restaurants in order: i) to analyze the nutrient contents of full course meals per servings, and ⅱ) by analyzing the above, to examine the amount and the quality of the foods served in the full course meals by Korean style restaurants in Changwon. A total of 20 restaurants in Changwon participated in this study, and two investigators visited there, consumed and investigated it. A key finding was that restaurant patrons tended to overconsume nutrients as compared to the Korean Recommended Daily Allowance(RDA), and restaurants generated large amounts of food wastes due to the excess food served. Other findings were as follows: 1) 1,821.2Kcal were served, 1,052.6Kcal were consumed and 768.6Kcal which is equivalent to 1/3RDA were thrown away on average. 2) The average carbohydrate:protein:fat(CPF) ratio of caloric nutrients was 42:27:31. 3) The correlation between the consumed and unconsumed calories was r=0.661 and the correlation between served and unconsumed calories was r=0.819. Both consumed and unconsumed calories were closely related to the served calories. 4) The result of the research showed that mean INQ in most nutrients was higher than 1.0, especially INQ in unconsumed food is mostly higher than INQ in provided and consumed food. 5) The unconsumed food and the meal prices were closely correlated in terms of price loss. These findings indicate the Korean style full course meals consisted of a high-protein, high-fat and high-caloric intake, which is similar to a westernized caloric nutrient pattern. They should also be strongly encouraged to play an active role in improving their customers’ nutritional status, as well as reducing the restaurants wastage of food. Lastly, further research should be conducted to improve the quality of the menus in Korean restaurants.

The goal of this study was to investigate moisture sorption characteristics of Lactobacillus brevis-fermented sea tangle Saccharina japonica, Mekabu fucoidan, and these mixture powders. Moisture sorption isotherms of powders were determined at 37℃ using the static gravimetric technique in a water activity (aw) range of 0.11-0.93. Equilibrium moisture content (Xeq) values of the fermented sea tangle powder were almost 3 times when aw<0.7 and increased upto almost 4 times when aw<0.9 higher than mekabu fucoidan powder. In these reason, to improve strong hygroscopic nature of the fermented sea tangle powder, fermented sea tangle and mekabu fucoidan powders were dissolved as ratios of 7:3, 5:5, and 3:7 (w/w) in a distilled water and then freeze dried. Xeq values of mixture powders were around average value of sum of both powders at all aw ranges. All moisture sorption isotherms of powders exhibited typical J-shaped type III. Xeq of mixture powders increased with increasing aw and decreased as increasing proportion of mekabu fucoidan powder. The Peleg model was found to accurately describe moisture sorption isotherms of powders. The results can be used to understand hygroscopic nature of powders, improve shelf life, and retain quality across postharvest processing.

This study was to investigate the changes in nutrition knowledge, nutrition attitude and food habit during 'meal management and diet' course to nonmajor university students by questionnaires. 280 students of Chungnam university who registered nonmajor 'meal management and diet' course in the 2003 were the subjects. The results of this study are as follows. BMIs of male and female students were 21.5 and 19.3. According to BMI, underweight subjects were $24.3\%$, normal and overweight (danger & obesity) subjects were each $62.4\%$ and $13.6\%$, respectively. The nutrition knowledge scores significantly (p < 0.001) increased from 12.1 to 14.0 after the lecture, and the uncertainty rate of nutrition know- ledge decreased significantly. Also, there were no significant differences in nutrition attitude score (39.5 to 39.8 points). Female subjects showed significantly (p < 0.05) higher nutrition knowledge scores (12.3 points) than male (11.4 points). $20\%$ of the subjects smoked and $82.9\%$ had alcohol drinks and $24.4\%$ exercised more than 3 times per week. The subjects who ate regular meals significantly increased from 9.3 to $12.5\%$ after the lecture, and smoking subjects decreased from 20 to $13\%$, but alcohol drinking subjects did not changed significantly.
