Four hundred and forty 1-day-old Arbor Acre broilers were fed commercial starter diets with 0, 250, 750 and 2,250 mg/kg of an alpha-amylase preparation from 1 to 21 days of age to investigate the effects of an exogenous enzyme on growth performance, activities of digestive enzymes in the pancreas and anterior intestinal contents and pancreatic amylase mRNA expression. Body weight gain (BWG) and average daily gain (ADG) increased linearly (p<0.01) with increasing levels of supplementary amylase but feed conversion ratio (FCR) was not affected. There was a negative quadratic change of protease and amylase in the small intestinal contents with the increase of supplementary amylase level. The activity of intestinal trypsin was also increased (p<0.05). Lipase was unaffected by amylase supplementation (p>0.05). The pancreatic protease, trypsin, and lipase were not affected by exogenous amylase levels. Consistent with the tendency for a linear depression of amylase activity, pancreatic ${\alpha}$-amylase mRNA was down-regulated by dietary amylase supplementation. The present study suggested that oral administration of exogenous amylase affected activities of intestinal enzymes and the production of pancreatic digestive enzymes in a dose-dependent manner.

The purpose of this study is to develop a life planning program for retired elderly people. This program is not a preparation program for elderly people prior to their retirement but a readjustment and re-planning their life after retirement. This program help retired elderly people to solve the life problem and set up a affirmative ones future image. Also this program pay regard to social, home backgrounds of this generation. The program consists of four session curriculums session 1 is entitled to &Make my future by oneself&, session 2 is &Enjoy healthy life as much as one can&, session 3 is &Have a heart for family& and session 4 is &Set up a mature old age&. A fled study has been conducted with ten retired elderly people who want to participated in the program voluntarily. 4 sessions each of which consists of 2 hours were performed at Korean Association of Retired Persons. Field test for program evaluation is designed to three steps: pre-test, post-test and one month follow-up test to measure the effectiveness of the program. According to evaluation results, the program shows a significantly positive effect on the improvement of elderly people's understanding about elderly life. At the one month follow-up assessment, the effect of program is still remained strongly even though there is a Partial slight increase or reduction which is not statistically significant. Most of the program participants have expressed high level of satisfaction with the program. For further study, we need various contents which are suited to larger group with diverse socio0-demographic backgrounds. At the same time, the program has diverse instruction methods which are pertinent to levels of participants.

With regard to the culture in cities this study aims to essential understanding and systematic approach to the culture. The "2011 Seoul Survey"report has been used to find out causality among the related variables. In the first place 'satisfaction of cultural condition' was operationally selected as a dependent variable for regression. For the purpose of controlling confounding factors for ceteris paribus effect correlation analysis was done between the dependent variable and all other variables respectively, which resulted in two groups of variables: group (1) - 6 variables of very significant correlations(p-value<0.01) and (2) - the other 6 variables of significant correlations(p-value<0.05). Then hierarchical regression was adopted to these 2 groups to analyse $R^2$ increment, statistical significance of independent variables, and multicollinearity(VIF; variance inflation factor). At last a regression model specified by group (1) as independent variables(they are 'social trust', 'satisfaction of walking condition', 'happiness index', 'preparation against old age', 'satisfaction of traffic condition' and 'hours for internet') shows that only 'social trust' variable has statistically significant and substantially strong effect on 'satisfaction of cultural condition.' This finding should be accepted on the following understanding; (1) urban culture has a collective attribute formed between people and society, (2) culture is somewhat telling and hearing stories and the confidence between tellers and hearers is essential in the mutual response and (3) stimulus is received by relationship in company with sense, emotion, thinking and action. In spite of restrictive external validity this finding can be used as a direction for promoting culture and a basis for related policy choice in cities.

Powered infant formula and baby food contaminated with Enterobacter sakazakii were reported to cause infection among infants and to be associated with sporadic cases and outbreaks of sepsis, menigitis, cerebritis, and necrotizing enterocolitis. Salmonella contamination of infant formula has also been responsible for multiple outbreaks. Other species of Enterobacteriaceae in powdered infant formula may be causative agents, about which there has been no report. Other pathogenic bacteria have been isolated from powdered infant formula but they were not associated with outbreaks among infant. While Enterobacter sakazakii caused disease in all age groups, premature infants under 28 days old and with birth weight are most sensitive to its infection. Even if low contamination level of the bacteria in powdered infant formula and baby food may not cause infection, the possibility to multiplicate during preparation and storage of reconstituted formula may increase. The etiological factors and pathogenecity of S. sakazakii have not been elucidated. There were wide variability in phenotype and genotype between its strains. S. sakazakii has been isolated from factory facility and surroundings more frequently than Salmonella and thus factory environment should be the source for post-processing contamination of the formula with S. sakazakii. Considering current technology to manufacture power infant formula and baby food it is impossible to sterilize powdered formula but the frequency of outbreak hazard by S. sakazakii can be reduced by pasteurizing the formula base before drying and shortening storage time of the reconstituted formula.

This study was to evaluate the effectiveness of nutritional counseling for farmers by using computer- based program to estimate pre - and post - knowledge and attitude changes. The desirable change of both knowledge and attitude focused on improving food Intake and early easing of body complaints. 311 agricultural workers in Korea were chosen for this experiment. The score was compared by 2 methods. In the first method, the scores were calculated from nutrient intake quantity and indices. In the second method, the difference of pre and post test of nutritional counseling by count of correct answers of foods and food preparation attitudes was measured according to different body complaints status. Major farming type was rice-planting(39%). The consciousness of health status of the subjects of less than 50 years old was good(42%), but it was only 20% in over 50 years' group. Female farmers felt uncomfortable in body complaints. Their body complaints were 2 times more than the male farmers, particularly, in over 50 years group. Nutrient intakes were lower in male based on the KRDA, except for vitamin C, niacin, and phosphate. Female farmers' nutrient intake was adequate based on the KRDA, but was low in vitamin A, pyridoxin, and iron. From the scores of knowledge and attitude by pre and post tests, counseling was efficient In nutritional education of all age groups, especially the older ones. The effect of counseling by farming type showed that the real agricultural workers had more increased score In the post test. This results Indicated that counseling about food, nutrition. and health to these workers was always effective. Therefore nutritional counseling and education program should be developed for different kinds of health and nutrition. It would be conducted to promote food behavior and improve nutritional and health status of farmers.

This study explores institutions that provide comprehensive services to senior citizens, including welfare, healthcare, and housing support. These institutions can be defined as centers that offer continual care and carry out policies related to senior citizens. In such institutions, senior citizens have access to information about aging and senior services. First, this study reviewed prior research on senior comprehensive support institutions and their accessibility, and the data led to several findings about the needs of the senior citizens and the proper locations of senior comprehensive support institutions. And this study used surveys to gather information on senior citizens' perceptions of services at such institutions. The survey results indicated that the elderly agreed with the priorities of comprehensive support institutions, and that it would be more convenient to visit such institutions if there were more than one per Dong (administrative district of Seoul). In response to these results, the ideal radius of each administrative district in the metropolitan area of Korea was investigated. Finally, the study also discussed the adequacy of this distance in comparison to that of current institutions in Japan. Combining these results, the study concludes that comprehensive support institutions for the citizens should be created and suggests appropriate distances and locations of such institutions.

The purpose of this study was to evaluate satisfaction degree on menu served and identify food preference of the meal served to 271 business and industry foodservice workers from 4 institutions by gender difference. The demographics indicated that male(54.6%) and female(45.4%) were about an half each, mean age was ranged from 20 to 39 years old. The workers were not contented with most of menu quality attributes served from past foodservice operation. Primary complaint was improper temperature of the meal. Most workers liked meat and fish(52.1%) the most. Sensory quality evaluation from all workers was 3.37 points out of 5 points. However, female workers rated higher on the most of menu(3.72 points) compared with that of male workers(3.35 points), indicating that satisfaction was higher in the female workers(p<0.05). Mean preference of all the menu according to food type also have shown higher in female(3.52 point) than in male(3.45 point). Best food preference according to food type considering cooking method of male was given to barley rice, boiled rice with assorted mixtures, marine product stew, and Kimchi stew. On the other hand, females cared for curried rice, hash rice, and spaghetti but males have shown low preferences to those foods females liked. Also, females liked more of fried, grilled and broiled food. However, both males and females showed indifferent taste about the food cooked with steamed and stewed. From the findings, the business and industry foodservice workers were not well satisfied with menu quality considerably and differed in food preferences by gender clearly. Therefore, the manager of foodservice institution require to consider composition of gender ratio in menu preparation along with sensory quality evaluation to lead the successful foodservice management.

This research, as a basic preliminary study for development of functional health food, is aimed at assessing the body fat reduction effect and for application to human body for such reduction in actual clinical settings by preliminary extraction of 2 types of wild edible greens, Lythrum salicaria L. and Aceriphyllum rossii. Subjects over the age of 19 and less than 60 years old with BMI value range of $23.0kg/m^2{\sim}29.9kg/m^2$ were recruited through screening were divided into experimental group and control group, each with 25 subjects, through randomized allocation. With both patients and evaluators wearing blindfold, the experimental group was orally administered with 4 capsules of 500mg of composite preparation containing the extracts of Lythrum salicaria L. and Aceriphyllum rossii 3 times a day for a period of 8 weeks while the control group was orally administered with 4 capsules of 500mg of placebo (fake food) with the same appearance as the preparation administered to the experimental group 3 times a day for a period of 8 weeks. After having carried out evaluation on physical examinations (body weight, BMI and body fat ratio, etc.), laboratory tests (general blood test, biochemical test of blood and urine test), lipid test, the changes were analyzed. There was no significant change between the 2 groups and within the groups in BMI and body fat ratio, which are the primary effectiveness evaluation at each time. There was no significant difference between the 2 groups in serum lipid and WHR, obesity related KOQOL, KEAT-26 which are the secondary effectiveness evaluations. There was no change between the 2 groups and within the groups in vital sign, CBC, BC and urin test. These results suggest that Lythrum salicaria L. and Aceriphyllum rossii ext. showed no significant reduction in BMI, body fat ratio and serum lipid. Additional confirmative clinical application test is needed in the future.
