  • We examined the effects of dietary nutrient content, feeding period, and feed allowance on compensatory growth, food use, chemical composition, and serum chemistry of juvenile olive flounder Paralichthys olivaceus. We placed 720 juvenile fish into 24 400-L flow-through round tanks (30 fish per tank).A $2{\time}2{\time}2$ factorial design (diet: control (C) and high protein and lipid (HPL) ${\time}$ feeding period: 8 and 6 weeks ${\time}$ feed allowance: 100% and 90% of satiation) was applied. Fish were hand-fed twice daily, based on the designated feeding schedule. Weight gain and food consumption were affected by both the feeding period and feed allowance, but not by diet. The food efficiency ratio was not affected by diet, feeding period, or feed allowance, but the protein efficiency ratio and protein retention were affected by diet and feeding period, respectively. We found that the full compensatory growth of fish was not achieved at a restricted feeding allowance.

  • Diet is closely related to an economic level, but few studies have reported on the relationship between the economic level and eating habits, especially in college students. Therefore, this study was conducted to clarify differences in eating habits with a focus on processed foods according to allowance level in college students. This study was a cross-sectional survey of 500 college students using a questionnaire. The questionnaire consisted of general characteristics, eating behaviors, purchase of processed foods, and preference and intake frequency of processed foods. All subjects were classified based on monthly allowance: less than \300,000 (n=149), \300,000~400,000 (n=177), and more than \400,000 (n=124). All survey results were comparatively analyzed among the spending money groups. As the level of spending money of the subjects increased, the rate of skipping meals, eating out, and unbalanced diet increased (P<0.05). The reason for consuming processed foods was because they are easy to prepare. The factor considered the most when buying processed foods was price. However, these results showed no significant difference according to level of spending money. As spending money increased preference for retort, convenience, canned, and bottled foods significantly increased. Intake frequency of dairy products was lower, and the frequency of processed foods was significantly higher with more spending money. This study found that a higher level of monthly allowance in college students, was associated with higher rate of skipping meals, eating out, and unbalanced diet, and the preference and intake frequency of processed foods were also high. These results suggest that spending money level in college students, as an economic indicator, is relevant to intake of processed foods.

  • Age, sex and the amount of activity determine recommended dietary allowances. So the method of developing RDA and their levels have been revised according as the physical condition of a nation improves and the amount of activity changes along with the variety of social situations. It can be seen from records that in Korea the absolute nutrient requirements for the people in Chosun Dynasty were first published in 1922. After that, in 1941 Gui Dong Han expressed his view that the standard health diets for the Japanese would be suitable for the people in Chosun Dynasty. In 1960, the temporary nutrition standards for the Koreans were established by the Ministry of the Health and Social Affairs. For these standards, males and females were respectively divided into three groups by age and nine nutrients were recommended for each group. In 1962, The Korean Association to FAO published the RDA for the Koreans. Since then, regular researches have been done. For these allowances, there were 16 age groups of men and women and ten nutrients recommended for each group. On the first revision in 1967, the fat allowance was presented at the ratio (12%) of fat calorie to total calories with no change in the number of age catagories and in the kinds of nutrients. And the basis of the riboflavin allowance was changed from the level of protein intake to that of energy intake. On the socond revision in 1975, there was brought 19 are catagories and ten nutrients recommended. On the third revision in 1980, age catagories increased to 22, and ten nutrients were recommended. On the fourth revision in 1985, there remained 21 groups by uniting the early and later periods of pregency. On the first revision in 1967, the recommended energy allowance was 3000 kcal, the highest level. Since then it has gradually been reduced. And it can be noticed that the protein allowance was high when food was difficult to obtain.

  • This study examined that what attributes of student satisfaction are more important when students use university cafeterias. Factors that are considered to be more crucial when students use a cafeteria, such as menu, taste, price, and cleanliness, were tested. Based on the research of previous studies, it assumed that the selection attributes of students' cafeteria were menu, taste, price, and cleanliness. With 301 surveyed questionnaires, the study was carried out by AMOS 23.0 and the Structural Equation Model was used for examining the hypotheses as statistical method in this study. In consequence of the hypothesis test on the main effect, the factors such as the menu, taste, price and cleanliness were found to significantly affect satisfaction. Then, the moderating role of gender, age and allowance was analyzed. However, students' university cafeteria selection attributes differed depending on their allowance only. The path coefficients from menu to satisfaction were more significant in the group with a smaller allowance, while the path coefficient from price to satisfaction was more significant in the group with a larger allowance. The study analyzed that the effect of selection attribute of students' cafeteria on the satisfaction, and influence of students' allowance, and provide meaningful implications when they choose the attributes.

  • The purpose of this study was quantitative and qualitative contents analysis of food and nutrition section in middle school textbooks of home economics, physical education and science. As a quantitative approach numbers of sentence lines tables, figures, photos, activities, and exercises were counted. As a qualitative approach, types of explanations were categorized by 7 criteria, and commons and differences of the contents of those subjects were compared. The conclusions of this study were summarized as follows: 1) Contents of food and nutrition section were divided into nutrients. water. energy, food groups, and nutritional problems. When average sentence lines of each were compared, those of nutrients were the longest in all 3 subjects. 2) When compared the numbers of tables, figures, and photos in 3 subjects of textbooks, there were more figures in home economics and science, and more tables in physical education. 3) There were more activities and exercises in home economics an science than in physical education. 4) The D(sentences with table) or E type(sentences with figure) was adapted for the explanation of nutrients functions, recommended dietary allowance, food sources, food groups, eating habits, and weight control in home economics: nutritions functions and energy metabolism in physical education : and digestion, body constituents, energy metabolism, and detection of nutrients in science. 5) Contents about classification and functions of nutrients. food sources deficiency water, energy contents of nutrients and obesity were shown in all 3 subjects. Food groups and eating habits were explained in detail in home economics whereas digestion of nutrients in the digestive tracts were explained in detail in science. Recommended dietary allowance for Koreans and basic food groups revised in 1995 were presented in home economics, whereas those revised in 1989 were presented in physical education. To avoid confusion, recommended dietary allowance for Koreans and food groups presented in physical education tex should be updated.

  • The purpose of this study was to provide basic data for developing nutrition education program focusing on the health-oriented food choice and purchase which affect the adolescents' health. The data was collected by means of questionnaire from the total of 273 students who were living in cities and myun district and final 253 questionnaires were analyzed by using the SPSS/WIN 10.0 program. The results are summarized as follows. First, the major source of information on food was mass media, especially advertisement and students spent $20{\sim}30%$ of allowance on food purchase. The students purchased cookies or ice cream mainly, once every 2-3 days at the store near house, after school, for appeasing hunger or thirst. The influence of gender, mother's education level, economic status of family, the amount of allowance, the period of receiving allowance, the details of allowance recording, school location on food purchasing behavior were significant(p<.05). Second, the price and taste were the most important factors when the students purchase food. Nutrition and food sanitation/safety were considered less important by the students. The factors considered when the students purchase food were significantly different between Sender, father and mother's education level, and the amount of allowance(p<.05). Third, middle school students' food purchase behavior were influenced by advertizement, friends, parents. The influence of advertisement, friends, parents when the students purchase food were significantly different between gender, mother's career, economic status of family, and the amount of allowance(p.<05). From tile result of this study, the middle school students consider price and taste more than the other factors related nutrition and health in purchasing foods. Therefore, it will be necessary to develope and enforce nutrition education program focusing on how to choose and purchase safe, nutritious, delicious and cheap foot for adolescents.

  • The influence of feed allowance on intake and nutrient utilization by Barbari goats given green maize (Zea mays) and potential feeding value of left-overs were studied. The goats were offered food at 3 levels to give left-overs of about 20% (T-1), 35% (T-2) and 50% (T-3) DM of offered amount. A marked effect of refusal rate on intake and digestibility of nutrients was found. The DMI, g/kg $W^{0.75}$ increased from 39.86 in T-1 to 50.91 and 66.55 g in groups T-2 and T-3, respectively. Allowing selective consumption at higher levels (T-2 and T-3), the intake of TDN and DCP from green maize was found not only to meet the maintenance requirement but provided surplus energy and protein for substantial production. The variability in diet selectivity between goats under different treatments was pronounced. As the level of food excess increased to T-3, the left overs had a higher IVDMD and crude protein and decreased cell wall constituents (p<0.05). Considering the substantial increase in intake and digestibility from feeding green maize at high allowances to goats, further studies are needed to develop practical feeding strategies.

  • These studies were conducted to: a) investigate work patterns and productivity indices, b) rate performance levels of employees and c) determine the suggested levels of personnel and labor hours for the effective labor control in school foodservice. Eighteen elementary school foodservices in Seoul were selected in order to analyze work patterns by the work sampling methodology. Allowance time and performance rating by VTR observation was done to determine the standardized labor hours. The results were as follows. The average percentage of each work function of the total work functions such as direct work function, indirect work function and delay were 65.57%, 8.12%, 26.31% respectively. The productivity index is 0.92 min/meal. The average working and delay hours per week of the foodservice director, foodservice employees and supply person were 33.64 hours, 23.25 hours, 38.52 hours respectively. The percentage of delay hours of total labor hours for foodservice employees and supply person were 42.27% and 24.0%. The standardized work hours and the appropriate levels of foodservice employees of 17 elementary school foodservices were examined: The average rating of the foodservice employees work was 1.19 and British Insulated Calendarer Cables (BICC) allowance rate was 19.40% on the average. The total work hours of foodservice employees were 172.64 hours per week and levels of personnel were 4.53 persons. BICC allowance rate was applied: The standardized work hours per week was 180.95 hours and appropriate levels of personnel were 4.11 persons based on legal 44 working hours.

  • The purpose of this study is to offer information related to recommended dietary allowances for young children and food guidelines for preschool children in Sweden. Sweden, located in Europe, is the most developed country for young child care system. Swedish nutrition policy background, Swedish recommended dietary allowances for young children, and food guidelines of early childhood education center in Sweden were used. The number of Swedish child care centers increased from 70,000 in 1970 to 700,000 in 2000. The Swedish Institute of Public Health promoted children's indoor and outdoor activity. The aim of the Swedish public health contains children's safety, good food habits, and eating food safely. Swedish Food Administration made recommended dietary allowance and food guidelines for children care centers. The aim of food guidelines was to increase energy, calcium, iron, and dietary fiber intake. Swedish RDA contains minimum and maximum intake as well as mean intake for macro and micro nutrients. The fat intake ratio of energy is increased for younger children. For preschool children, the food guideline is determined by dietary allowances for breakfast, lunch, and snack respectively. Food guideline contains meal time schedule, menu for each meal using food model, amount of food for age group, and recommended dietary allowance for each meal. It is recommended for Korean early childhood education center: 1) Korean RDA for young children should be made range of intake, minimum and maximum intake. 2) Food guideline should be make for Korean child care center. 3) Korean child care centers should offer an afternoon snack twice for children who return home late. 4) Nutrition education program for preschool teachers should be developed for children's good eating habits and health promotion.

  • The purpose of this survey was to investigate the nutritional status of special working persons related to health status, nutrient intake and living environment. The survey was conducted on workers in 9 general hospitals and 2 factories from Nov. 24 in 1979 to Jan. 20 in 1980. Nurses, medical doctors on intership or residency, and factory workers were chosen as subjects because of their irregular working hours, i.e., they sometimes work during the day and. sometimes at night. The total number of subjects was 417 for nurses, for medical doctors was 91, and was 216 for factory workers, all together 724 subjects were investigated. The results obtained are summarized as follows: 1) Average nutrient intake of subjects per day. For nurses the caloric intake was 1743 Kcal. This was composed of carbohydrate 251g(57.6%), protein 81g (18.5%), and fat 46g (23.9%). Other nutrient intake, such as iron (16mg), thiamin (0.98mg), riboflavin (1mg) was lower than the recommended dietary allowance. For male medical doctors, the caloric intake was 2064 Kcal, This was composed of carbohydrate 288g (55.8%), protein 102g (19.8%) and fat 56g (24.4%). Other nutrient consumption, such as riboflavin (1.31mg) was lower than the recommended dietary allowance. For female medical doctors, the caloric intake was 1909 Kcal. This was composed of carbohydrate 156g(53.7%), protein 90g (18.9%) and fat 58g (27.4%). For male factory workers, caloric intake was 1699 Kcal. This was composed of carbohydrate 317g(74.5%), protein 64g (15.0%) and fat 20g(10.5%). Other nutrient intake, such as vitamin A (4765IU), ascorbic acid (46mg) and riboflavin (1.11mg) were lower than the recommended dietary allowance. For female factory workers, the caloric intake was 1630 Kcal. This was composed of carbohydrate 287g (70.5%), protein 65g (15.8%) and fat 25g (13.7%). Other nutrient consumption, such as iron (15mg), riboflavin (1.04mg), ascorbic acid (42mg), and vitamin A (4334IU) was lower than the recommended dietary allowance. The percentage of animal protein to total protein was 65.2% in nurses, 67.4% in male medical doctors, 64.9% in female medical doctors, 38.6% in male factory workers, and 45.6% in female factory workers. 2) The average Kaup's value of subjects was 1.9 in nurses, 2.2 in male mcdical doctors, 1.9 in female medical doctors, 2.0 in male factory workers, and 2.1 in female factory workers. 3) The health status of subjects according to their self diagnosed answer was as follows; The percentage of food health was 82. 7% in nurse, 82.7% in nurse, 83.5% in medical doctor, and 56% in factory workers.
