This study attempted to analyze the general and physical characteristics, the status of physical function, the type and number of current diagnosis and self-reported symptoms, healthy life mode and food preference according to self-rated health (SRH) of older adults (135 men and 270 women). It also attempted to assess the factors affecting the SRH standards in agricultural and fishery areas located in southwestern Korea. The subjects considered themselves as being 'good'(57.6%), 'normal'(29.6%) or 'poor'(12.85) SRH, meaning positive self-rating of health and it was found that the correlation between factors such as the gender, current marriage status, monthly wage, the reception of the government's livelihood subsidy and subjective economical status and the SRH were significant. Regardless of the categories of obesity, a large number of the participants rated themselves as 'healthy', but not statistically significant. The subjects who reported poor ADL and IADL capacities, indicators of the status of physical function, were significantly more classified to the 'poor' health category and vice versa (P<0.001). The reported chronic diseases in this study that have lasted more than three months, were lumbago, sciatica, arthritis, high blood pressure and peptic ulcer. The current ratios of smoking, drinking and exercise were 85.3, 39.0 and 18.6%, respectively. The less drinking and exercising there was, the higher the 'good' SRH categories obtained (P<0.05). The respondents who had less chance of eating sour and hot foods estimated their health status as being better.

The primary objective of this research was to investigate the recognition, preference and the present using status of yam for the data which will be useful to make consumers intake more yams and to develop more yam processed products. Almost all respondents who had eaten yams liked it, and Andong people eat more yams than Daegu people. About 60.3% respondents who like yams cited the reason was "it's good for health". Among the respondents who had eaten yams recognized it as nutritional, healthful, and diet food compared with the respondents who had not eaten yams. Recognition degree was higher when the preference for yams was higher. Among the types of yam processed cooking, according to intake ratio, yam juice formed 38%, followed by bleaching(17%) etc. Among the types of yam processed food, powdered tea formed 34%, followed by yam gruel(24%), yam drinks(19%) etc. It showed that respondents eat very few foods made from yams and yam processed food. As for purchasing yam processed food, the result showed that the main concerns of the respondents were the "ratio of yams"(24.9%), followed by "tastes"(21.3%) etc. The largest group (29.4%) of the respondents suggested that the improvements of yams were "diversification of the processed food" followed by "improved taste"(26.4%) while 62.5% of the respondents indicated that they would buy yams after its improvement, which showed a good prospect of yam processed food.

Purpose: The aim of this study is to examine the effects of egg consumption and suggest proper guidelines for consumption of eggs by determining the relationship between eggs and cholesterol. Methods: Literature review was conducted on the relationship between nutritional, functional properties of eggs and serum cholesterol, as well as cardiovascular disease. Results: Eggs, which are a good protein food with complete amino acid composition, contain vitamin A, riboflavin, vitamin $B1_2$, folic acid, vitamin D, vitamin E, vitamin K, calcium, iron, choline, selenium, ${\beta}$-carotene, lutein, zeaxanthin, etc. However the egg yolk has a high cholesterol content, which is associated with chronic diseases, including heart disease and hypertension. As a result, its intake is subject to regulation. Outbreak of heart disease by yolk intake can show different results depending on the characteristics of the subjects, amount of egg intake, and the implications of other foods eaten. It is difficult to determine whether eggs are beneficial, as they are the main supplying source for other major nutritive elements as well. Several research studies insist that when cholesterol intake increases by 100 mg, the level of serum cholesterol increases by 2.2~4.5 mg/dL and when serum cholesterol increases by 1%, the risk of heart disease increases by 2%. This indicates that a large intake of eggs can increase the risk of heart disease. Although the cholesterol of egg yolk and serum cholesterol are correlated, it is insufficient to conclude that only cholesterol and not other components are related to heart disease. In fact, other components in egg such as various unsaturated fatty acids and phospholipids could be related as well. Rather than concluding egg as a 'good' or 'bad' food according to its cholesterol content, it is important to define egg as a part of dietary patterns. Conclusion: Generalizing an indiscriminate and uniform amount of egg intake for all seems inadequate. However, patients with diabetes or heart disease should pay particular attention to the amount of egg intake. As for the norm, eating egg with vegetables as a substitute for other animal products seems beneficial.

This survey was conducted to investigate the relation of children's obesity index to their mothers' food habit during the October in 1995. The survey covered a total of 492 mothers whose children were in the fifth grade of elementary schools in Cheju City area. The results are summarized as follows: 1.The surveyed children's average WLI(Weight-Length Index) is 107.08. WLI shows that 16.1% of them are overweight, 16.1% obese and 49.8% ideally weighted. The mothers' average BMI(Body Mass Index) is 22.4. 21.8% of them are underweight and 69.4% normal. The children's obesity index is significantly correlated to their fathers', but not significant to their mothers'. 2.As to the food habit I (balance of nutrients intake), 58.4% of the mothers have 'excellent' or 'good' food habit and the mean score is 14.95 out of maximum possible score 24.0. Concerning to the food habit II (intake of sugar, fat and salt etc.), 87.4% of mothers have 'good' or 'fair' food habit and the mean score of is 13.34 out of maximum (possible score) 20.0. The mothers' food habit I and II, as a whole, have no significant effect on the children's obesity index, but in some items the significant relations are founded. The children's chesty index is significantly related to the intake of eggs (P<0.05) and pan-broiled or fried foods (P<0.05). The amount of mothers' food intake is significantly relevant to their obesity index (P<0.001), but not significantly to their children's. The food habit of mothers who have taken midnight snack almost every day are significantly related to their children's chesty index (P<0.05). The findings of the study emphasize the importance of the nutrition education to ensure health and better physical fitness for children and their mothers.

This study sought to determine family restaurant patrons' attitudes toward nutrition and healthy menus. A written questionnaire was handed out to 300 dine-in customers at the three different sites of T brand family restaurant. A total of 265 questionnaires were usable for data analysis, resulting in 88% response rate. Two attitude statements eliciting the strongest agreement were that 'Diet and chronic diseases risk are closely connected each other(4.44)' and 'Koreans are more nutrition & health conscious than they were in the past(4.41)'. The attitude statement-that nutrition is important when I eat out- received the lowest scores(2.92), which indicated that nutrition was not yet considered the most important factor when dining out. 23% of the respondents were interested in healthful foods, while 30% said they were unconcerned. Nutrition conscious group showed significantly (p<.000) higher attitude scores for most of statements than unconcerned group. Significant differences were found in age groups(p<.05, p<.01, p<.001), income levels(p<.05), educational levels(p<.05), health status groups(p<.05), and weight control interest groups(p<.05). Older respondents, respondents with higher income and educational levels were more interested in nutrition and healthy menus. Respondents who reported good health status and showed higher interest in weight control were more interested in nutrition and healthy menus. These findings indicate that restaurant firms should respond to consumers' increased interest in nutrition and healthy menus by offering healthful menus and increasing nutrition marketing activities. This may positively result in increasing customer counts and revenue as well as customer satisfaction level and brand image of restaurant firms. Moreover, restaurant firms are strongly encouraged to play an active role in promoting public's nutritional and health status because increasing consumption of meals away from home will seriously affect good health of our consumers.

With recent increases in demand for women's social participation, children have tended to favor western-style foods and dislike vegetables (Veg.). The objective of this study was to evaluate dietary behavior and Veg. intake in 612 elementary school children (339 boys; 273 girls) in Gyeonggi-do. 66.5% of the subjects reported that they liked Veg. The most frequent reason given for this preference in Veg. liking group was that vegetables were 'delicious' (35.6%), followed by 'nutritious' and 'frequent intake'. The most frequent reason given for disliking Veg. in the Veg. disliking group was that vegetables are 'not delicious' (94.6%). Approximately half of the subjects had correct knowledge about vegetables. The total score of general nutrition knowledge was 7.7 points (a perfect score is 10 points) and the majority of students generally had good dietary behaviors. The Veg. liking group scored higher on knowledge about Veg., general nutritional knowledge, dietary behavior, and Veg. preference than did the members of the Veg. disliking group (p<0.001). The 'active' group had the highest score for dietary behavior (p<0.001), and the scores for dietary behavior and Veg. preference increased with increasing self-rated health status (p<0.001). The score of normal BMI group for nutritional knowledge about Veg. was higher than that of the underweight group (p<0.05). The higher self-rated academic score group showed higher on knowledge about Veg., general nutrition knowledge, dietary behavior (p<0.001) and Veg. preference (p<0.05). Dietary behavior and preference of Veg. were positively correlated with nutritional knowledge. To improve health by increasing Veg. intake, education about the nutritional importance of Veg. should be needed, and continuous nutritional education is recommended to foster good food habits and Veg. preferences in children.
