Protein conjugation of curdlan belonging to $\beta$-1, 3-glucan was carried out to improve it surface functionalities. The glucan was mixed with phosvitin, {TEX}$$\alpha$_{s}${/TEX}-casein, lysozyme or ovalbumin, respectively. The mixture was freeze-dried, and he resulting powder was incubated at 6$0^{\circ}C$ and 79% relative humidity for 12 days in order to generate a controlled Maillard reaction between curdlan and proteins. conjugation with unfolding proteins, i.e., phosvitin and {TEX}$$\alpha$_{s}${/TEX}-casein, drastically increased the solubility of the glucan, whereas lysozyme and ovalbmin did not. The solubility in water of curdlan was 3.44% for the phosvitin conjugate and 1.09% for the {TEX}$$\alpha$_{s}${/TEX}-casein conjugate. SDS-slab polyacrylamide gel electrophoresis showed that curdlan was solubilized due to covalent binding with phosvitin. Emulsifying properties of curdlan were substantially improved by the conjugation with phosvitin and {TEX}$$\alpha$_{s}${/TEX}-casein. Emulsion stability of the curdlan-phosvitin conjugate was about 2.9 times greater than that of the curdlan-phosvitin mixture.

Farm economy is getting worse because of the free trade trends in agriculture sector and unreasonable application of market economy principles to agricultural products. And The worldwide issues of environmental pollution as well as want of food, water and energy make human future be anxious. In addition, consumers raise questions in argument about safety of foods produced by traditional farming or imported. So I propose the urban-rural living community movement(URLCM) as an alternative plan for sustainable domestic agriculture. URLCM based on environmentally friendly agriculture and community consciousness will be able to solve many of present issues on agriculture and rural society through incessant interchanges between urban and rural community. This URLCM has to be basically founded on principles of symbiosis-coexistence and life circulation. So those that have to be driven forward arc organizing producers and consumer cooperatives, making environmentally friendly rural region and products, combining with consumer cooperatives, training the participants and so forth.

The rural living improvement in Japan operates in considerations of socio-eoonomic circumstances of rural community as in Korea. After 1945 the program emphasized the improvement of living conditions such as poverty alienation improvement of house and toilet nutrition after war, From 1955, health programs including better cooking and nutrition, house modification and improved living conditions corresponding to the goal of the developed country were carried out. In 1965. the goal of the rural home economics was focused on the harmonized production and living, improvement of the levels of rural living, health and building rural community. From 1975, the goals of the program were to organize the farming in the better ways and improvement of rural women's role. In 1985, making agreeable living conditions was emphasized under the goal of vital rural society. From the period of Heysey(1989${\sim}$), for better living of rural people the government is emphasizing the programs including farm labor management, utilization of farm products, farm management and rural environments. Recognizing the important influencing resources of agents in extension services, on the job and education was implemented step by step from basic to planning to upgrade competencies. The government is trying to construct better with infrastructures, encouraging direct selling the value-added processed food from local farm products with rural people's real name and other countryside resources. Major programs in the 21st centuries are building better rural society with men and women together and considering elders as well as new farmers.

BACKGROUND/OBJECTIVES: Food shortage situation in North Korea has gained much interest, however food insecurity caused by the food shortage in North Korean households has not been much investigated. This study examined food security experiences and food consumption pattern of displaced North Korean households currently living in South Korea. SUBJECTS/METHODS: Food security experience among 51 North Korean households living in South Korea was examined using the Household Food Insecurity Access Scale (HFIAS) in three time points: immediately before childbirth, immediately before leaving North Korea, and immediately before entering South Korea. Meal/snack consumption frequencies and food diversity were also examined. RESULTS: Food security situation was the worst at the time of immediately before leaving North Korea with the average HFIAS score of 10.05. The households that were food insecure, they tended to be "severely" insecure. Although majority of the subjects reported having three or more meals a day, food diversity in their diet was very low with the average food diversity score of 2.17 immediately before childbirth and 1.74 immediately before leaving North Korea. Their diet appeared to heavily rely on grain and vegetable. CONCLUSIONS: This study is one of few that specifically examined food security of North Korean households with a pre-developed scale, and that demonstrated food security situation at different time points in quantified terms. Replicating this study with different groups of North Korean households for different time points would allow more complete understanding of impacts of food shortage. Food diversity score could provide a good way to examine changes of food consumption occurring to North Koreans in the process of adaptation. More attention to the changes occurring during adaption to South Korea should be given to understand the process and impact and to prepare public nutrition policy for the re-unified Korea.

In this research, we examined a total of 681 children(kindergarten, schoolchild, and adolescents) who live in Seoul and Gyoung-gi in 2007. The parents of the respondents seemed to have a normal average body mass index, and the majority of the parents had bachelor's degrees. Across all age groups, most of the fathers were office workers and the mothers were mostly house wives. The most preferred food was meats, and the least preferred food was vegetables. Results showed that all age groups have a snack once or twice a day, except boys from the schoolchild group. All age groups liked ice cream, fruits, and juices in their snacks. For eating-out, boys from the kindergarten group mostly preferred Chinese food, girls from the infant group mostly preferred Korean food. In addition, boys and girls of the schoolchild and adolescent groups mostly preferred Korean food. For cooking methods, the result of preference showed that boys from the kindergarten group preferred roasted meats, and girls from the kindergarten group preferred roasted meats, steamed rib and fish. Both boys and girls in the schoolchild group preferred roast meats, and boys from the adolescent group preferred stir-fry and girls from adolescent group preferred pot stew.

The purpose of this study was to examine household food insecurity and the associations of food insecurity with socioeconomic characteristics, food behaviors, health status and nutrient intake among elderly people in a rural area. This study included 191 elderly people (mean age = $72.0{\pm}7.4$) in Jeollabuk-do, Jangsu-gun. House food insecurity was measured using an adapted version of the USDA short form household food insecurity scale, and nutrient intake measured by a 24-hour dietary recall. Only 15.2% of the subjects were in food-insecure households, 84.8% of the elderly households were food-secure. The food-insecure households were significantly lower in the number of family, frequency of shopping, and perceived health status than the food-secure households. In addition, they had serious tooth problems and NSI (Nutrition Screening Index) scores. Food-insecure households were significantly lower in most areas of nutrient intake (energy, protein, fat, Ca, P, Fe, K, Na, Zn, Vit. $B_2$, niacin, Vit. E), and also lower in nutrient intake compared to dietary reference intake (energy, protein, P, Fe, K, Na, Vit. $B_1$, Vit. $B_2$, niacin, Vit. E). These results suggest that the household food insecurity measures used in this study were an important indicator of nutritional well-being among elderly persons in the rural area. Food insecurity should be considered an important issue to public health and food service programs should be expanded for food-insecure households in rural areas.

This study investigates drinking attitudes and behaviors of university students. The sample included 355 students living in Busan, Korea. The questionnaire addressed general background information (gender, age, grade and monthly pocket money), drinking attitudes (understanding the effects of alcohol on the body, stereotype of drink, age at the first drink, the drinking companion at the first drink, reasons for starting to drink, main drinking companions, major reasons for drinking, the history of drinking alone, and reasons for drinking alone), drinking behaviors (the cost of each drinking occasion, drinking amounts, the frequency of drinking, the frequency of heavy drinking, the type of alcoholic beverage, and the places of drinking). A few respondents (both male and female students) started drinking while in high school (p<0.05), and most respondents drank with friends (males: 91.0%, female: 92.2%). The main reasons for drinking were the mood for male student (46.3%) and relationships for female student (49.1%) (p<0.05). Male respondents consumed more than seven glasses of soju (39.9%), whereas female respondents, five to seven glasses (49.7%) (p<0.05). On average, the respondents drank one to two times a week (males: 47.9%, females: 51.5%) and experienced heavy drinking one to three times every three months (males: 19.1%, females: 21.0%) (p<.05). The results suggest that students with frequent alcohol consumption and heavy alcohol dependence are likely to face problems and thus require aggressive intervention strategies that target them specifically.

The purpose of this study was to evaluate the nutritional status of elderly women living in residential homes by estimating nutrients and food intakes. Food consumption survey was conducted by 3-day 24hr recall method with 99 elderly women aged 65 to 90 years from three residential homes in Seoul, Choonchun and Chunan and 46 free-living elderly women aged 65 to 88 years from Chunan as control group. Food intake data was converted into nutrient intake using computer aided nutritional analysis program. Mean energy intake and percentage of recommended daily allowance (RDA) of residential home residents were 1696㎉ and 101% of RDA while those of control were estimated as 1939㎉ and 119% of RDA. On average, absolute amount of nutrient intakes of residential home residents were slightly higher than control group. Subjects in control group showed significantly lower carbohydrate and vitamin A intake, while vitamin C intake was higher. However, nutrient intake quality determined by INQ (Index of nutritional quality) was significantly higher among control subjects in most nutrients except vitamin A than residential home residents. Intakes of calcium, vitamin A and riboflavin of all subjects in this study were less than 75% RDA meaning that nutritional status of calcium, vitamin A and riboflavin was insufficient and could possibly result in nutritional deficient. Some food groups such as milk or other dairy products must be strongly suggested to improve nutritional status of elderly women in this study. According to the results of this study, meal plans of residential homes are quite adequate in quantity of micronutrients, but need to be improved in both quantity and quality of micronutrients.
