Ruminal degradation characteristics and intestinal availability of crude protein (CP) in four animal-origin feeds (fish meal, meat meal, viscera meal, feather meal) were estimated by mobile nylon bag technique. Three ruminally and duodenally cannulated Holstein dairy cows (average body wt. 550kg) fed a diet containing 40% concentrate and 60% orchard grass hay on a dry matter (DM) basis. Assuming that the outflow rate of diet in rumen is 5% per hour (k =0.05), contents of quickly degradable CP (QDP), slowly degradable CP (SDP), and undegradable CP (UDP) in the rumen were 27.6%, 9.4%, 63.0% for fish meal, 34.3% 28.1%, 37,6% for meat meal, 43.9%, 12.5%, 43.6% for viscera meal, and 14.4%, 15.8%, 69.8% for feather meal, respectively. Intestinal CP degradability was 51.0% for fish meal, 27.2% for meat meal, 37.9% for viscera meal and 56.2% for feather meal. Available UDP in the intestinal tract was contained 288 g, 217 g, 246 g and 423 g per kilogram DM of diet in fish meal, meat meal, viscera meal and feather meal, respectively.

A feeding trial was conducted to evaluate dietary protein sources replacing fish meal for parrot fish, Oplegnathus fasciatus. A control diet with white fish meal as a protein source was included. White fish meal in the isonitrogenous diet was replaced with each of 22% meat meal, 17% blood meal, or 31% soybean meal. Triplicate groups of 25 fish initially averaging 26 g were fed four experimental diets for 7 weeks in a flow-through tank system. Weight agin and feed efficiency in fish fed diet containing 17% blood meal (this diet also contained 45% white fish meal) were not significantly different from those in fish fed the control diet (P>0.05). Fish fed diet containing 22% meat meal had lower weight gain and feel efficiency than those of fish fed the control diet (P<0.05). weight gain of fish fed diet containing 31% soybean meal was not different from that of fish fed the control diet, but feed efficiency of fish fed the diet was lower than that of fish fed the control diet.

This study examined the different meal duration expectations and dining characteristics of customers each stage of service (order, cook, check), and investigated the impact of perceived meal duration on customers' satisfaction. The procedures consisted of four phases. During the first phase, the different meal duration expectations and dining characteristics of customers of an Italian restaurant in Seoul were examined by survey at each stage of service. The second phase investigated the impact of perceived meal duration on customer' satisfaction. The third phase compared perceived meal duration and actual meal duration. The last phase suggested appropriate meal duration for maximization of customer' satisfaction. We also examined the effects of meal time (lunch or dinner) on meal duration preferences. Customer satisfaction was decreased with longer perceived meal duration for the order and check stages and too short perceived meal duration for the cook stage. To determine appropriate meal duration for each service stage, the relationship between perceived and actual meal durations was examined. This study confirms that customers dining at restaurants preferred a longer cook time and that a shorter meal duration at dinner decreased satisfaction ratings more when compared to lunch.

Objectives: This study aim to determine adolescent meal time, which provides the important context of parent-child sharing time. We divided mealtime into family meal and alone meal, and analyzed the time/space context of each meal time as well as the social determinations. Method: We employed adolescents age 10-18 who live with married patents and attends school at the present (n=5,128) from the original data of Korean Time Use Survey. Results: More adolescent were engaged in family meal rather than eating alone in daily bases. However, the trend show difference by day of week and academic grade; family meal are more prevalent in weekends rather than weekdays. As adolescent reaches high school age, the proportion of eating alone beats the proportion of family meal time. Most of the meal occur at home. Having meal outside was relatively scares, especially on weekdays. Tobit and logistic analysis reveal that, on weekday meal, less school hours, more time spent at the private academy, having family leisure event, and long mother's housework hours were positively associated with family meal time. In weekend model, father's education gradient was associated with family meal time, showing higher the father's education level, there were higher chance of having weekend family meal. As for the eating alone, relevant factors were similar with family meal but the directions were the opposite; having family leisure were negatively associated with alone meal, both weekdays and weekend. Long academy hours, meal preparing and leisure alone were positively associated eating alone. Overall, weekday meal time was strongly linked with adolescent daily schedules and time use, while for weekends meal, in both family meal and alone meal, the influence of parent factors were discovered. Conclusion: The results indicates that alone meal and the family meal are not exclusively related but seem to be complementary. Families tend to enjoy family meal yet, there are some necessary situation that adolescent need to be on their own. Increase in ready-made food industries, growing independence of children by age seem partly allow adolescent children to eat alone. Careful attentions may require for monitoring weekends meal situation and the family factor of adolescent in future studies.

This study investigates perception of the free school meal program, satisfaction of school meal, and eating habits of free and paid school meal program students in the Busan area. Between 20 to May 2020, a total of 350 students were researched, of which 177 belonged to the second grade of high school (free school meal program), and 173 were from the third grade of high school (paid school meal program). 96.0% free school meal program students and 89.0% paid school meal program students responded to the necessity of a free school meal program, which was significantly different between the two groups (P<0.05). All questions regarding the perception of the free school meal program, which were responded to by more than 3 points, were considered positive. 'Decline of the school meal's quality' had the maximum response, from 64.4% and 76.4% free and paid school meal program students, respectively, and was significantly different between groups (P<0.05). Paid school meal program students wasted significantly more school food than the free school meal program students (P<0.001). 'Not delicious' was responded by 56.0% free school meal program students and 50.0% paid school meal program students. Evaluating satisfaction of the food quality and service categories was determined to be higher amongst free school meal program students than the paid school meal program students (P<0.05). Considering our study data, we propose that with the gradual expension of free school meal programs, inclusion as part of the education system will serve as a foundation for proper eating habits, and compulsory education will help improve students' health and quality of life.

This study was carried out to investigate the effect of replacing fish meal or soybean meal with feather meal or bromelain treated feather meal in broiler diets on the performances and nutrient utilization. Two hundred and twenty-five broilers were randomly allotted to five dietary treatrnents((1) control, basal diet; (2) PFM 50, 50 % of the fish meal replaced with bromelain treated feather meal; (3) PFM 100, 100% of the fish meal replaced with bromelain treated feather meal; (4) PSM 20, 20 % of the soybean meal replaced with bromelain treated feather meal; and (5) PSM 40, 40% of the soybean meal replaced with bromelain treated feather meal) in a 5-week feeding trial. In the overall period, body weight gain of the PFM 50(1,807 g), PSM 20(1,816 g) and PSM 40(1,823 g) were the highest and that of the PFM 100 was 1,744 g. The body weight gain of the control(1,698 g) was the lowest(p < 0.05) among treatments. Feed conversion was significantly(p< 0.05) improved when bromelain treated feather meal replaced 20% of the fish meal in the basal diet. Digestibilities of dry matter, ether extract, organic matter and phosphorus were not different among the treatments. Digestibility of crude protein of PFM 50(65.87 %), PSM 20(67.18 %) and PSM 40(67.56%) were the highest, and that of the control(54.49%) was the lowest(p < 0.05) among treatments. Arrunonia and hydrogen sulfide gases from the feces were significantly(p < 0.05) decreased in chicks fed the PFM 50, PSM 20 and GFM 40 diets, when observed after 3 weeks of feeding trials. Feed costs of the control and PFM 50 were 604 and 629 won, respectively but that of PSM 50 was 820 won. Therefore, replacement of fish meal with bromelain treated feather meal in the diets for chicks could be useful for economic production.

The purpose of this research was to observe the management system of 18 free meal service centers for the low-income homebound elderly in Chungcheongbuk-Do In order researchers interviewed staff members of the free meal service centers. Based on the results of interviews with staff members of the meal service organization. only two centers used a standard recipe. and most of the meal preparation was controlled under the experience of volunteers. Only two meal service centers employed dietitians due to the lak of budgets. The cost of a meal per day ranged from ￦ 556 to ￦2,750 and the number of attendants at meal service ranged from 35 to 350 persons. The budget for most of the meal service centers is not enough to provide meals for the elderly who want to participated in free meal service programs. Home delivery meal service was not considered due to the lake of manpower and areal dispersion in rural ares. Most meal service organizations did not cooperate with other community service organizations. Several improvement strategies are recommended for the effective running of the free meal service centers. First, a nutrition specialist should be included in the staff members of the service organization to provide nutritious meal service to the elderly Second, a joint control system might be introduced into the present system to reduced the cost and the recover the limitations of areal dispersion. Third, service, coordination should be considered to overcome the problem of lake resources.

The purpose of this study was to compare the effects of soup temperature on hunger, energy, and nutrient intake. The hot meal consisted of 400 g of hot beef-vegetable soup (75$^{\circ}C$), Yubu Chobap, Bulgogi, cucumber pickle and radish pickle. The cold meal component were the same as the hot meal except 300 g of water (8$^{\circ}C$) and boiled vegctables (100 g), instead of the hot beef-vegetable soup ot the hot meal. Thirst, core temperature and blood pressure were also measured before and after consumption the test meals in a within-subjects, repeated measures design. 30 women consumed 17% more kilocalories, 13% more protein and lipid and 16% more carbohydrate in the cold meal than in the hot meal. The core temperature at the end of the test meal was higher in the hot meal than in the cold meal. Energy and nutrient intake were inversely correlated with the hunger scores within 1 hour after the hot meal, however those are not related with each other in the cold meal. So hunger feeling might be disturbed in the cold meal. It is concluded that energy and nutrient consumptions were higher in the cold meal, partly because of the distrubed hunger feeling in the cold meal.

Two hundred and sixteen single comb white egg layers of the White Leghorn hens of 24 weeks of age were randomly allocated to 12 groups with three replications of six hens in each. Hens were fed in a factorial arrangement 2${\times}3{\times}$2, on diets containing either 16 or 18% crude protein with 0, 3 or 6% fish meal, replacing groundnut meal with soybean meal. Soybean meal incorporation improved (p<0.05) egg production, feed intake, feed conversion efficiency and egg weights. Egg quality traits of specific gravity, shape index, albumen index, yolk index and shell thickness remained unchanged. Laying performance was significantly (p<0.05) better at 18% than on 16% dietary protein level. Use of fish meal linearly improved egg production and feed conversion efficiency on diets supplemented with groundnut meal and fish meal incorporation showed quadratic improvement on feed conversion efficiency with SBM diets at 16% dietary protein level. Therefore, use of soybean meal as substitute of groundnut meal is recommended in layer diets, at 16% dietary protein level and fish meal incorporation could be beneficial for layers.

This fundamental study was undertaken to evaluate the nutritional value of Canola rapeseed meal which has been increasingly used as a by-product with the demand for the food oil resource. To compare the nutritive values among rapeseed meal and soybean meal, two experiments were carried out by using rats. One was a digestibility test of rapessed meal and the other was the growth rate of rats for 21 days. The chemical compositions , blucosinolate and amino acids of defatted repeseed meal and defatted soybean meal were analyzed. After one week feeding, nitrogen excretion in rats was measured to study FER, PER , TD , BW , and NPU of the meals. The amount of crude proteins in defatted rapeseed meal and defatted soybean meal were 45.5% and 37.9%. The glucosinolate content of defatted rapeseed meal was 0.04% . The body weight gain of defatted rapeseed meal was not signficantly different from that of defatted soybean meal (p>0.01). After one week feeding, there was no significant differencess in organ weight and serum components between two groups(p>0.01). It was presumed that the rapeseed meal has enough possibility for developing food to use as a protein source like a soybean meal protein. However, more careful experiments are needed to clarify the nutritional value of rapeseed meal of Canola since the lipids composition of blood tended to be different when the rapeseed meal and soybean meal were used.
