This study examined foodservice management performance in child-care centers and suggests ways in which meal service quality can be improved. Questionnaires were distributed to 51 child-care facilities. The majority of respondents were facility directors (dietitians) and their facility type was tax-paid (92.2%). The dietitian response rate was 51.0%, and the majority (96.2%) were hired with co-management status, visiting a facility once a week (76.0%). Only 52.1% of the facilities had menu planning by a dietitian, and improvements were needed in terms of planning menus with standardized recipes, especially for infant meals. The monthly food cost per child was 47,394 won, and the labor cost for a co-management dietitian was 3,670 won per child, indicating 21.8% and 1.8% of the tuition fee, respectively. Other necessary improvements included: more reliable food purchasing management, securing additional foodservice equipment, and better sanitation management. In addition, respondents rated the following as requirements to ensure high quality meal service: 'modernized foodservice equipment and facilities', 'government financial support', and 'information on nutrition and foodservice management provided by dietitians'. Based on the study results, the following are recommendations for improving meal service quality in child-care centers: Dietitian placement should be extended to facilities of over 50-capacity in addition to their current placement in facilities of over 100-capacity, and co-management dietitians should have their control span restricted to two facilities instead of five. Finally, nationwide nutrition support plans and nutrition education programs should be developed and implemented by dietitians, and their roles should be extended to foodservice mangers as well as nutrition teachers.

A feeding trial was conducted to determine the effectivity of microbial treatment on eliminating the toxicity of weevil-infested sweet potato roots, and to assess intake level and performance of broilers fed microbiologically-treated, weevil-infested sweet potato meal. Weevil-infested sweet potato meal was treated with Aspergillus awamori (terpene-degrading fungus), dried, and mixed with other ingredients. One hundred twenty (120) broiler chicks were randomly distributed to treatment diets containing 3 types of sweet potato meal (healthy, weevil-infested, and microbiologically-treated, weevil-infested) incorporated at 2 levels (12% and 24%) in the ration, following the $2{\times}3$ factorial in CRD with 4 replicates per treatment. Voluntary intake was high with healthy sweet potato meal, even at 24% in the ration, especially at later stage of broiler development. Weevil infestation of sweet potato meal, even at 24% in the ration, especially at later stage of broiler development. Weevil infestation of sweet potato roots significantly reduced voluntary intake and broiler performance even at 12% level in the diet, much more at 24% level (p<0.01). Microbial treatment, however, was found to alleviate such problem, especially at 24% level of incorporation (p<0.01). "Toxicity" of weevil infestation, in terms of enlargement of liver and spleen, in the absence of mortality, was only apparent at 24% level of incorporation in the ration. Again, this was minimized by microbial treatment (p<0.01), and is therefore recommended at high levels of incorporating weevil-infested sweet potato meal in broiler diets. Microbial treatment constitutes an added cost, so that economic analyses should be done to find out whether increases in broiler performance, or reduction in the toxic effects of terpenoid compounds, outweigh the cost of treatment before a definite recommendation can be made for its commercial application.

The purpose of this study was to research the current home delivered meal (HDM) service programs for seniors living in the community. Fifty seven centers which operated a HDM service program were surveyed with respect to their administrative structure, menu management, food purchasing and production management, hygiene and equipment and facility. -Statistical data analyses were completed using the SAS 8.1 program for descriptive analysis and t-test. The results showed that 55 percent of the study group were from 70 to 79 years old. All of the participants received free HDM. As a result of the meal cost analysis, the meal cost at 56.1% of the HDM service centers was from ￦2,000 to ￦2,499 per meal. A total of 68.4% of the HDM service centers were operated without the services of a dietitian. According to the menu analysis, all nutrients except Vitamin B2 were at levels of more than 33% of the Recommended Dietary Allowances for Koreans. Although 96.6% of the HDM service centers required a therapeutic diet menu for the health of the elderly recipients, 68% of the directors responded that they could not afford to serve therapeutic meal. Food purchasing, menu planning and other foodservice management processes were handled by non-professionals, such as volunteers, cooks or social workers. Forty two percent of the HDM service centers never used standard recipes. For determining portion sizes, 75.4% of the HDM service centers depended on personal experience. Finally, the current HDM service programs for the homebound elderly were not operated systematically. It is suggested that professionally trained personnel should be included among the staff members to provide a more effective HDM service. The HDM service programs should be supported financially and systematically by the government.

The purpose of this study was to analyze the food service management practices and productivity in 49 elementary schools in the Daegu and Gyeongsangbuk-do areas. Survey questionnaires were used to obtain a variety of quantitative and qualitative information, including general food service management and productivity, on elementary school food service systems. Descriptive analysis, $\div$2-test, t-test and one-way ANOVA analysis were used as the statistical methods in this study. Eighteen elementary schools were located in urban areas, 13 in provincial areas and 18 in isolated areas. The average number of meals was 565.1, with a significant difference (p＝0.001) between the areas. The average cost per a meal was 1151.0 Won, with a significant difference (p＝0.001) between the areas. The productivity Index (meal/hour) was 13.5, with a significant difference (p＝0.001) between the areas. There was a significant positive correlation of the productivity Index between the total number of meal, the number of employees, the total food cost, meals per employee and the employee's working period. There was a significant negative correlation between the productivity Index and the number of side dishes, the lost per meal, the labor cost per meal and the employee's job satisfaction degree index (JDI).

This trial was conducted to determine the effects of feeding a diet containing solid-state fermented rapeseed meal on performance, nutrient digestibility, intestinal ecology and intestinal morphology of broiler chickens. A mixed liquid culture, containing approximately 5 log cfu/ml Lactobacillus fermentum, Enterococcus faecium, Saccharomyces cerevisae and Bacillus subtilis was prepared in a 1:1:1:1 ratio. A basal substrate (BS) containing 75% rapeseed, 24% wheat bran and 1% brown sugar was mixed with the liquid culture in a ratio of 10:3. Over the 30-day fermentation, isothiocyanates were reduced from 119.6 to 14.7 mmol/kg. A total of 168, day-old male Arbor Acres broiler chicks were assigned to one of three dietary treatments including a corn-soybean meal based control diet as well as two experimental diets in which the control diet was supplemented with 10% of the BS containing unfermented rapeseed meal or 10% of the BS containing rapeseed meal subjected to solid state fermentation. There were 8 pens per treatment and 7 birds per pen. From days 19-21 and days 40-42, uncontaminated excreta were collected from each pen for digestibility determinations. In addition, digesta from the colon and ceca were collected to determine the number of lactobacilli, enterobacteria and total aerobes. The middle sections of the duodenum, jejunum, and ileum were collected for intestinal morphology. Over the entire experimental period (d 1-42), the weight gain and feed conversion of birds fed fermented rapeseed meal were superior (p<0.05) to that of birds fed nonfermented rapeseed meal and did not differ from the soybean control. On day 42, birds fed fermented rapeseed meal had higher (p<0.05) total tract apparent digestibility coefficients for dry matter, energy, and calcium than birds fed non-fermented rapeseed meal. Colon and ceca digesta from broilers fed the fermented feed had higher (p<0.05) lactobacilli counts than birds fed the control and non-fermented rapeseed meal diets on day 21 and 42. Fermentation also improved (p<0.05) villus height and the villus height:crypt depth ratio in the ileum and jejunum on day 21 and 42. The results indicate that solid-state fermentation of rapeseed meal enhanced performance and improved the intestinal morphology of broilers and may allow greater quantities of rapeseed meal to be fed to broilers potentially reducing the cost of broiler production.

The purpose of this study was to investigate the current status of foodservice management in organizations delivering meal boxes for low-income children during summer vacation. A survey was conducted with persons in charge of meal box production and service of these organizations via mail. Out of 114 questionnaires distributed nationwide, 100 were analyzed(87.8% analysis rate). Over half(53%) of the organizations delivered meal boxes consisting of rice and side dishes while the rest delivered side dishes only. About 81% of the organizations received KRW 3,000 per meal from their local governments and the rest received KRW 3,500. Only 28% of organizations had employed a dietitian. Over one-third(38%) of the respondents were unaware of the official nutritional standard of the foodservice program for low-income children during vacation. Most of the organizations(94%) had menu planned in advance. The average percentage of food cost was 84.1%. Over 40% of the organizations did not keep food samples for sanitation test(43%) and did not take any measures for keeping food temperature during delivery(45%). The organizations delivering rice and side dishes were more likely to be located in cities rather than rural areas and received higher reimbursement rate. The organizations receiving reimbursement of KRW 3,500 or hiring a dietitian were more likely to use standardized recipes, keep food samples for sanitation test, or take measures for keeping food temperature during delivery compared to the counterparts. Respondents reported that increasing reimbursement rate was the most necessary for improving the quality of meal box. This study results showed that the meal box delivery service for low-income children was not properly managed during the vacation, with regards to menu planning and food production. It is recommended that reimbursement rate for meal boxes should be adjusted depending on meal box types and local conditions.

Three hundred and fifty-two growing pigs were utilized in three growth trials to investigate the effects of crystalline amino acid supplementation on growing pigs' growth performance and feed consumption. In Exp. 1, diets were formulated on the basis of digestible amino acids. Utilization of rapeseed meal plus cottonseed meal (R + C) in diet supported similar average daily gain (ADG), feed/gain (F/G) and cost per gain (p > 0.05) to group of soybean meal (SBM). In Exp. 2, 14% CP diets containing equal amount of cottonseed meal and rapeseed meal were formulated with the addition of threonine and/or tryptophan. Supplementation with threonine improved ADG and F/G (p < 0.05). Supplementation with only tryptophan made no benefits for ADG of growing pigs. In Exp. 3, diets with different threonine level were formulated. Increasing dietary threonine to 0.54% improved (p < 0.05) ADG and F/G compared to 0.45% dietary threonine. Increase in dietary threonine did not improve ADG (p > 0.05) but decreased F/G (p < 0.05) because of a decrease in average daily feed intake. Pigs fed diet with dietary threonine/lysine ratio of 67.5% supported optimum growth performance.

This experiment was conducted to investigate the effects of soybean meal (SBM) of different origin (Korea, India or Brazil) on performance, fecal microflora and economics of grower pigs. A total of 144 grower pigs (initial BW, 10.4 kg) were randomly allotted to six treatments on the basis of BW. Pig's diets containing SBM were formulated based on the total amino acid (TAA) or true ileal digestible amino acid (TIDAA) levels. Pigs fed domestic SBM diets had greater (p<0.05) overall ADG, ADFI and final body weight and apparent total tract digestibility (ATTD) of DM, GE and CP (phases I, II and III) than those fed diets containing SBM originated from India or Brazil. Moreover, greater (p<0.05) ADG, ADFI, feed /gain (F/G), and ATTD of DM, GE and CP were observed in response to diets formulated on a TIDDA basis when compared with those formulated on a TAA basis. The fecal microflora was not affected (p>0.05) by dietary treatments. The overall feed cost per kg body weight gain was less (p<0.05) for diets formulated using domestic SBM than for those containing SBM from India, while the feed cost per kg body weight gain was less (p<0.05) for diets formulated prepared on a TIDAA than a TAA basis. These results indicate that domestic SBM has better quality than SBM imported from Brazil or India and better performance was obtained when diets were formulated based on the true ileal digestible amino acid (TIDAA) content.

The purpose of this study is to examine the current congregate meal service program for homebound elderly. One hundred three meal service centers in charge of the congregate meal service programs as part of the elderly foodservice program were surveyed for administrative structure, menu management, food purchasing and production management, hygiene, equipment, and facilities. Statistical data analyses were completed using the SAS 8.1 program for descriptive analysis and ANOVA. The meal cost of 54.4% of the congregate meal service centers ranged from ￦l,500 to ￦l,999 per meal. According to the menu analysis, all nutrients except calcium and Vitamin B2 were at levels of more than 33% of the Recommended Dietary Allowances for Koreans. A total of 81.5% of the centers were operated without the services of a dietitian, and food purchasing, menu planning and other foodservice management processes were handled by non-professionals, such as volunteers, cooks or social workers. Although 88.3% of the centers required a therapeutic diet menu for the health of the elderly, most directors (77.6%) replied that in their current status they could not afford to serve therapeutic diets. These results suggest that financial and systematic supports by government is very necessary. Fifty-five percent of the centers never used standard recipes. For determining portion sizes, 93.2% of the congregate meal service centers depended on the personal experience of the personnel. Finally, the current congregate meal services for the homebound elderly were not operated systematically. To improve the elderly food service program, it is strong1y recommended that it be managed by Professionals.

Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, nitrogen-free extract, energy and essential amino acids in animal-based feed ingredients were determined for olive flounder (Paralichthys olivaceus). A reference diet (RF) was formulated to contain 1.0% chromic oxide (Cr₂O₃) as an inert indicator. Nine test diets were formulated to contain RF and one of the feed ingredients (pollock meal [PM], jack mackerel meal [JMM], anchovy meal [AM], cod meal [CM], sardine meal [SM], sand eel meal [SEM], tuna meal [TM], meat meal [MM] and squid liver meal [SLM]) at a 7:3 ratio in each diet designated as PM, JMM, AM, CM, SM, SEM, TM, MM and SLM, respectively. Olive flounder, averaging 150 ± 8.0 g, were stocked at a density of 25 fish per tank in 400-L fiberglass tanks attached with fecal collection columns. Feces were collected from triplicate groups of fish one time a day for four weeks. Dry matter and crude protein ADCs of CM and SEM were significantly higher than the other tested ingredients. Lipid ADCs of JMM, CM and SEM were significantly higher than the other test ingredients. Energy ADCs of CM and SEM were significantly higher than that of the other tested ingredients. The availability of amino acids in CM was generally higher than the other animal protein sources. PM exhibited the lowest amino acid availability among the treatments. Interestingly, MM exhibited significantly higher nutrient digestibility than several marine-based ingredients. However, CM and SEM are seeming to be highly digestible and effective to use in olive flounder diet compared to the other tested ingredients. Overall, the results of this study provide information about the bioavailability of nutrients and energy in animal feedstuffs to apply when formulating cost-effective practical feeds for olive flounder.
