This study was carried out to investigate quality characteristics of white breads with cabbage powder(CP) (0, 2.5, 5.0, 7.5 and 10.0%). L-value was significantly decreased by addition of CP, but a and b-values were increased(p<0.05). The degree of pH of dough and bread weight increased with increasing CP concentration, while bread volume, specific volume, and baking loss rate became reduced. The hardness of the breads added with CP was higher than that of the control group. Also, In sensory analysis, the breads with CP showed generally low scores in color, flavor, taste, texture and overall acceptability compared with the control. Taken together, the 2.5%, 5.0% treatment showed similar results with the control group, as compared to other treatments. Addition of CP influenced the color, bread volume and other rheological properties, which is disadvantageous for the quality of white bread. However, compared with the control group, up to 5% CP substitution for flour didn't show significant defferences in sensory test.

The dietary habit, health condition and the cognition concerning the health food have been surveyed with the help of the 151 old people living in In-Cheon and Seoul. In this study, the old are classified as an institution for the aged and the old in their own home. The preference and mental health condition influenced on dietary habits have been surveyed as wall. Their dietary habits such s three meals a day and a regular meal time have show) that they have generally good eating habits. Psychologically, the old in an institution for the aged think their health condition is not so good in comparison with the old in their own home. The old in their own home have good condition in that they can go up the stairs, exercise often and walk relatively well. Moreover, men's health condition is better than women. The old generally like meats(especially beef) and prefer sesame oil, perilla oil, soy been oil to Western oil. They like sweat flavor the most and hot, salty taste in order. Thier favorite cooking method is a pot stew, soup and season. The difference between dietary habit and mental health based on an academic career, an allowance and a residential condition shows that the old who live alon have relatively terrible eating habit and the more learned, the better. The more pocket money they have, the better dietary habits they have. The old feel glommy in general and the old in an institution are more depressed and it is statistically significant.

The purpose of this study was to invesitage the optimum cooking method, which ingridients mixing ratio and decortication of white and black sesame gruels, were examined by sensory and mechanical tests. As the results of sensory evaluation for the decortication white and black sesame gruels with the levels of 50, 100, 150, and 200％ sesame per rice l00ｇ, the flavor, nutty taste, and the overall preference were increased with the increase of sesame add. The gruel which made with decorticated sesame roafting for 7 minutes was proferable. The gruels 150% decorticated white and black sesame roasted 7 min had better overall preference. In the mechanical measurement for the white sesame gruels, L value tended to be decreased, while ‘a' and ‘b' values as well as viscosity tented to be increased as the sesame ratio and roasting time increased. In black sesame gruels, L value tended to be decreased, while ‘a' and ‘b' values as well as viscosity tended to be increased when sesame ratio was increased. In correlation between sensory evaluation and mechanical measurement of the white and black sesame gruels, color, flavor, nutty taste of sensory evaluation were correlated with the mechanical measurement. The optimal material mixing ratio for gruels was rice 100 g, white and black sesame 150 g, and water 1075 g.

Purpose: This study compares the snacking pattern, diet, lifestyle, and food preference of children by evaluating the most frequently eaten snacks. Methods: The survey enrolled 435 students from three elementary schools in Gyeonggi. Based on the most frequently eaten snacks, the subjects were divided into 3 groups: fruits and milk/dairy products for natural snacks (NS, n = 114); noodles, snack foods and fast foods for meal-like snacks (MS, n = 74); cookies, beverages and bread as sweet snacks (SS, n = 247). Results: Compared to the MS group, preferences of the NS group were significantly higher for jabgokbap (cooked rice with multi-grains, p < 0.05) and saengchae (seasoned raw vegetables, p < 0.01), and significantly lower for gogitwigim (deep-fried meat, p < 0.05). Taste preference of the NS group was considered to be more desirable; the taste preference of more subjects was 'sweet taste' in the SS group, 'spicy taste' in the MS group, 'salty taste' in the MS and SS groups, and 'sour taste' and 'bland taste' in the NS group than the other groups. Compared to the MS and SS groups, the NS group was determined to exercise more frequently; exercising for more than 30 minutes/day was determined to be 76.3% in the NS group and 58.1% and 57.9% in the other groups (p < 0.01). Moreover, a higher proportion of subjects in the MS group tended to answer 'not hungry' as the reason for leaving school meals, as compared to other groups (p = 0.055), thereby suggesting that inappropriate snacking habits interfere with regular meals. Conclusion: This study provides evidence that healthy snacking habits, which include natural snacks such as milk/dairy products and fruits, are important for children during the elementary school years, since these habits are associated with healthier diet, lifestyle, and food and taste preferences. These results provide basic information for developing nutritional education materials for elementary school children.

Recently, GIS(Geographic Information System) has been developed to personalized service for providing the specialized services that is aimed to personal user based on mobile communication. The existing GIS system provides comprehensive and simple information but GIS System for personalized service must provide the adjustive information through the personal interest profile based on POI(PoInt of Interest). This paper describes the intelligent retrieval geographical information service module for providing personal oriented geographic information service. Our proposal model consists of user preference profile, acquisition of POI through hybrid network (Wireless LAN, CDMA), service platform and implementation of prototype system. Implementation model can apply to the life information service like restaurant, oil station, convenient store and etc.

In collaborative recommendation two models are generally used: the user model and the article model. A user model learns correlation between users preferences and recommends an article based on other users preferences for the article. Similarly, an article model learns correlation between preferences for articles and recommends an article based on the target user's preference for other articles. In this paper, we investigates various combination methods of the user model and the article model for better recommendation performance. They include simple sequential and parallel methods, perceptron, multi-layer perceptron, fuzzy rules, and BKS. We adopt the multi-layer perceptron for training each of the user and article models. The multi-layer perceptron has several advantages over other methods such as the nearest neighbor method and the association rule method. It can learn weights between correlated items and it can handle easily both of symbolic and numeric data. The combined models outperform any of the basic models and our experiments show that the multi-layer perceptron is the most efficient combination method among them.

The last half of the twentieth century brought many new opportunities and challenges to the traditional South Korean family. One area of change that challenges the traditional South Korean family is the availability of new food sources, specifically the introduction of commercial restaurants that offer new types of food in untraditional settings. This research investigated the perceptions of South Korean mothers'(n = 104) regarding the patronage of quick service style restaurants by their children through the use of Q sort methodology. The results showed that even though children do influence the decision making process when determining where to eat away from home, Korean mothers still play a very prominent role in planning the family's food consumption. While Western food styles and practices can provide a variety of food selections and service styles, care should be taken not to over utilize the quick service restaurants' in place of traditional foods.
