The purpose of the study was to compare the satisfaction level on hospital meal size and actual intake rate of hospital foods between elderly and middle aged patients. Sixty one middle aged and one hundered thirty two elderly patients were surveyed on the foods served in the hospital-rice, soup, meat/fish, vegetable, kimchi and daily products. Compared to the middle aged patients, the more elderly thought the serving size of rice was too big(p<0.05), and those of soup, meat/fish and kimchi tended to be too big. There was no difference in the satisfaction level on the serving size of vegetable dish between two age groups. In actual intake rates of hospital meal there were no significant differences between the elderly and middle aged patients. However, the elderly male ate significantly(p<0.05) less amount of rice than the middle aged male and the elderly female ate significantly(p<0.01) less amount of meat/fish then the middle aged female. Satisfaction levels and actual intake rates were significantly correlated in all food items.
A survey of ecological aspects of food, focused on breakfast of 1,526 adults with various professional occupations such as professors, teachers, employees of government, bank and company, and 1,928 students of various levels in the urban areas, was conducted from March, 1984 to February, 1985. The results were shown as follows: Significancy was found between appetite at breakfast, and bed time, status of sleep, eating outside the home on the previous evening, meal or snack of the previous late evening, and exercise before breakfast. The study showed that only 15.2% of the subjects had a good appetite at breakfast; 28.1% had a poor appetite; others had indifferences. About 45% of the subjects had their evening meal between 7pm. and 8pm.; bank employees had breakfast further later than 9pm.. Surprisingly, 31.3% of the subjects had snacks later than 10pm..Nearly one-fourth of subjects, in general, and 34.4% of the subjects in Seoul, had breakfast by themselves due to different schedules of family members. Breakfast patterns of the subjects during a period of 7 days were distributed as follows: 5.5 times for rice-oriented Korean meal; 0.6 times for bread type meal; 0.9 times for the omission of meal. The study described that the subjects who had bread type breakfast consumed only 3.7 items of food, whereas the subjects who had Korean breakfast consumed 7.1 items, on the average. Better breakfast eating habits for an adequate daily diet should be emphasized through nutrition education for adolescents and at the worksite.
This study was designed to find out passible correlations between the growth rate and daily food intakes of two hundreds E and Y kindergarden children in Seoul, Korea. The subjects adapted in this study were 5-year-old boys and girls and their physical growth index was calculated by means of body weight and height. Dietary survey was performed by recording all the foods taken at daily basis for six days. The results are summarized as follows: 1. Living circumstances of the subjects. a) In most cases, subjects had two to three brothers and sisters. b) About 39% of boys were brought up by cow's milk and 34%, by mined nourishment with mother's milk and cow's milk, while approximately 40% of the girls were brought up by mother's milk and 37%, by mixed one. Of the whole subjects, 70% were weaned at the age of $7{\sim}18$ months. c) Fruit juices were introduced to children at about 3 months old in 40% of the subjects. d) Approximately 60% of the children had their meals regularly and the rest of the subjects had irregularlity in their meal, mainly because of excess consumption of snacks. e) About $20{\sim}40%$ of total income of sampled families were spent for foods. f) The most favorate main dish was steamed rice, other favorate foods were beef and pickled cabages for boys, and ham and dried laver for girls. The least favorate foods for both sexes were oyster, shellfish and various vegetabes. Fruits, juice, milk, and ice cream are more popular snacks among children. 2. Nutrition survey a) Insufficient caloric intakes were shown in both sexes, comprising 90% of daily recommended dietary allowences for boys and only 75% for girls. Iron intake was strikengly low, reaching only 62% of R.D.A. for boys and 72% for girls. b) The total caloric intake was composed of CHO 62%, protein 18%, and fat 21% respectively. c) The consumption of animal protein comprises 55% of total protein intake. d) The cereal consumption was found to be the highest at the level of 43%. e) When the total caloric intake was divided into each meal and snack, snack took the highest part in any other meal. Each figure showed as follow; breakfast 21%, lunch 27%, supper 22% and Snack 30% for boys, and 23%, 22%, 25% and 30% for girls, respectively. 3. The result of statistical analysis. a) There was a significant relationship between the growth rate and the caloric intake of the subjects at the level of 0.05
A feeding trial was conducted to evaluate the effects of replacing fish meal (FM) with ensiled shrimp by-product (ESB) in a cassava root meal and rice bran-based diet on the performance and carcass characteristics of growing pigs. Thirty six crossbred (Large White$\times$Mong Cai) pigs, with an average initial BW of 19.4 kg, were randomly allocated to one of three different dietary treatments in which the crude protein of the FM was replaced with 0, 50 or 100% ESB. The animals were fed restrictedly and at the end of the experiment at a BW of about 90 kg, 6 representative animals in each treatment group were slaughtered for carcass quality evaluation. Animal growth performance and daily feed intake were significantly reduced (p<0.05) by the inclusion of shrimp by-products in the diets, whereas feed conversion ratios and carcass measurements were not significantly affected (p>0.05). Daily weight gains of the pigs fed the 100% FM diet and 50% ESB diet were significantly (p<0.05) higher than those of pigs fed the 100% ESB diet. In conclusion, from an economical as well as performance point of view, ESB can replace 50% of the crude protein of FM in cassava root meal and rice bran-based diets for growing pigs with a low genetic growth potential.
Studies were conducted with nine barrows, average initial body weight $44.5{\pm}2.1kg$, fitted with a T-cannula at the distal ileum, to determine the apparent ileal (and true) digestibility (AID and TID) of CP and AA in different cultivars of rapeseed meals and soybean meal. The barrows were fed either a casein diet or one of eight corn starch-based semipurified diets, formulated to contain 17.0% CP (DM basis) with one of seven different cultivars of rapeseed meal or soybean meal as the sole source of dietary protein, according to a six-period, nine-treatment, incomplete Latin Square. Chromic oxide (0.5%) was used as a digestibility marker. The pigs were fed of 4% of body weight twice daily, at 08:00 and 20:00 h. Ileal digesta were collected at 2 h intervals daily from 5 d to 7 d. The AID or TID values of CP and most AA (Cysteine excluded) were significantly lower in the rapeseed meals than in soybean meal (p<0.05). There were significant differences in the AID or TID values of CP and AA among the seven different cultivars rapeseed meals (p<0.05); the seven rapeseed meals were arranged according to the size of the AA digestibility values of the rapeseed meals from the greatest to the least, as Zayou 59, Youyan 7, Ganyou 16, Qingyou 2, Huaza 3, Ningza 1 and Lianglou 586; differences in CP, AA, NDF and ADF contents in the rapeseed meals were mainly responsible for the variation in the AID or TID values of AA among rapeseed meals. The AID value of CP can be used as an index of the AID or TID values of most AA in rapeseed meals. However, the AID value of CP was less appropriate as a direct indicator of the AID or TID values for cysteine, methionine, tryptophan, phenylalanine and proline.

This study evaluated the effect of microwave-dried black soldier fly (Hermetia illucens) larvae meal (HILM) as a dietary protein source for broiler diets. A total of 250 male broilers were randomly allocated to five dietary treatment groups (10 replicates and 5 birds·pen-1) which were respectively fed the following: a control diet (HI0) and four experimental diets in which soybean meal was replaced with 2 (HI2), 4, 6, and 8% HILM. At the end of the study (35 d), blood samples were collected from 10 randomly selected broilers (1 bird per pen) to determine serum parameters. Then, the broilers were slaughtered to determine volatile fatty acid (VFA) profiles in cecal digesta. The average daily gain and average daily feed intake linearly decreased (p < 0.01), and the feed conversion ratio linearly increased (p < 0.05) according to the inclusion level of HILM; however, there were no significant differences between the HI0 and HI2 groups. Dietary HILM increased (p < 0.01) the total VFAs in cecal digesta and decreased (p < 0.05) the triglyceride level in the blood. The broilers fed HILM had lower (p < 0.01) serum phosphorus levels; dietary HILM increased (p < 0.05) the serum calcium level. The total VFAs in cecal digesta were positively influenced by the dietary microwave-dried HILM. However, a low inclusion level (2%) of HILM in broiler diets is proper in terms of growth performance and health.

This study was conducted to investigate the utilization of defatted soybean meal as a substitute for fish meal in the diet for juvenile flounder (Paralichthys olivaceus). Duplicate groups of average weighing 35 g were fed one of four isonitrogenous ($54{\%}$) and isocaloric (575 kcal/100 g diet) diets containing $0{\%}, 10{\%}, 20{\%} and 30{\%}$ soybean meal for 45 days. Survival rates of all groups were $100{\%}$, Weight gain of fish decreased with increasing dietary soybean meal levels, However, this value was not significantly different between fish fed the control and $10{\%}$ soybean meal diet (P > 0.05). Feed efficiency and protein efficiency ratio decreased with increasing dietary soybean meal levels, but no significant differences were found among fish fed the control, $10{\%}\;and\;20{\%}$ soybean meal diets (P > 0.05). Daily feed and protein intake increased with increasing dietary soybean meal level. Crude protein and moisture content of liver tended to decrease and crude lipid content tended to increase with decreasing of dietary soybean meal levels. Plasma total cholesterol levels of fish fed the diets containing $20{\%}\;and\;30{\%}$ soybean meal were significantly lower than that of fish fed control diet (P < 0.05), Plasma GOT level significantly increased with increasing dietary soybean meal level (P < 0.05). It is concluded that soybean meal can be used as a partial substitute for fish meal up to $10{\%}$ in this dietary formulation for growth of juvenile flounder.
With the object of the study id every possible correlation between daily food intake and growth rate of primary school students, aged eleven years old, the author distributed prepared questionnaires through 200 children of 5th grade in both sexes in K private primary school, Seoul. Specific object of this study were included following three points: such as daily food intake records for six days. daily food intake records for six days. school records of sample children at the end of 4th grade. physical growth index calculated by means of weight and height of sample children at the first part of the 5th grade. CR. t. F. test as well as percentage calculations were included for statistical analysis. The result of this study were as follows: 1. For the living circumstances a) Average numbers of brother and sister in sampled family were two to three. b) Approximately 50%of the children were brought up by mother's milk at their infants and about 35% of children were weaned at the age of 7 to 12 months. c) Thirty to forty percent of the respondents revealed irregulity in their meal time due to early school time in the morning. d) Monthly average expenditure for daily food reached 20 to 29% out of total income. e) The most favorit foods reflect as follows: The most favorit main dish is boiled rice mixed with other careals and side dish beaf. Fruits and juice are more popular snack among whole children. 2. Nutrition survey a) The calcium and thiamine were the most limited factors out of daily nutrients consumption. b) The total calory intake were composed of carbohydrate 63%, protein 16% and fat 21% respectively. c) The total food intake were composed of 20 to 24% of animal source of foods and 76 to 80% of plant source of foods (vegetables, grains, fruits) d) The total protein intake were composed of 46% of animal protein and 54% of others. e) The grain stuffs consumed in the largest quantity at the level of 50% out whole food groups. f) Twenty four percent of total food intake came from snack between meal time. 3. The result of statistical analysis were as follows: a) The correlation between the calory intake and plysical growth index revealed statistical significancy at the level of p<0.001. b) The correlation between the protein intake and physical growth index revealed statistical significancy at the level of p<0.001. c) The correlation between the meal time and physical growth index revealed statistical significancy at the level of 0.02
The purposes of this study were: 1) to investigate the operational and financial characteristics of contract-managed high school food services in Seoul, 2) to analyze the financial performance of high school food services 3) to develop guidelines for meal pricing and facilities investment costs. From Oct to Nov 2001, questionnaires were mailed to 249 high schools that were managed by contract food service companies. A 40.2% response rate was recorded. The results of this study were as follows: 1. Student enrollment in high schools run by contract-managed food services was 1,518, with a 68.5% participation rate in the school lunch program. The average meal price was 2,141 won. 2. Based on the income statement analysis, average total sales were 410,440,504 won and average net profit was 16,098,558 won. 3. The optimum food cost per meal was 1,200-1,300 won per meal, calculating using the methods of conversion factor, RDA (Recommended Daily Allowance), and nutrient exchange unit. 4. Guidelines for meal pricing were developed using the modified actual pricing method based on facilities investment cost, number of meals and food cost. The ratio of labor cost, general management expenses and ordinary profit were adopted from the schools with liability. The food cost, depreciation and interest cost were calculated based on unit meal. 5. The guideline for facilities investment was developed based on the number of meals, meal price and food cost. The guideline included the maximum facilities investment cost paid by the contract food service management company. (Korean J Nutrition 36(5): 528∼535, 2003)
The aim of the study was to explore the current status as well as personal views, attitudes, and beliefs regarding daily meal consumption (DM) and food supplement use (FS) in conjunction with the improvement of health condition of the women. Eight focus group interviews were performed and the interview material was condensed systematically with the aim to extract core meanings related to DM, FS, and menopause-associated health. Participants were 40 in number and showed ages ranging from 45 and 60 years with various menopausal status. Current status and beliefs about DM, resources of purchase motivation of FS, types of FS that are currently used, and perceived effects and personal beliefs about FS are discussed. Theme content analysis revealed 3 themes for beliefs about DM, 5 themes for beliefs pertaining FS, and 4 themes for the association between DM and FS. Non-dietary factors such as positive mental attitude and exercise appeared to be also important to maintain good health. The bottom line message from this study may be that proper nutrition through daily meals is essential for good health, while food supplement are used merely to supplement the diet. Findings from this study may deepen our understanding of how women who translate their lifespan through "menopause" perceive the roles and meaning of DM and FS, suggesting health professionals need to monitor and evaluate DM and implement strategies targeting the improvement of daily meal quality of middle and older aged women.
