Soybean meal (SBM) is a major protein source in poultry feeds and one of the best quality ingredients because of the relatively high protein content, good amino acid profile and bioavailability. But soybean meal quality is largely dependent on the processing technology and origins. In this experiment, effects of three different soybean meals were evaluated in layer (experiment 1) and broiler (experiment 2). Soybean meal sources used in the experiments were the US-originated dehulled soybean meal (USDHSBM), India-originated non-dehulled soybean meal (India SBM) and Brazil-originated non-dehulled soybean meal (Brazil SBM). Experiment 1 was conducted during growing and laying periods and evaluated the interactive effects of soybean meal sources according to feeding periods on growth performance and egg quality. Experiment 2 was conducted during growing period (day 1-35) and finishing period (day 35-42). The growth performance was measured for the same periods and any possible interaction between soybean meal origins and crude protein levels was also studied. In experiment 1, chicks fed India SBM utilized feed more efficiently (p<0.05) than those fed Brazil SBM from day 29 to day 42. The body weights of layers during the laying period had no relation to egg production. But egg weights were significantly heavier in all the USDHSBM fed groups than other groups (p<0.001) and depended on feed protein source during growing period (p<0.001). The average egg weight of the USDHSBM fed group scored the highest value (65.4 g), followed by the Brazil SBM fed group (62.1 g) and India SBM fed group (62.1 g). There was an effect of interaction between origins of soybean meal fed group in growing and laying period on eggshell color (p<0.01). Eggshell was significantly stronger in the USDHSBM fed (for growing period) groups than other groups (p<0.05) on $31^{st}$ week. Haugh's unit (HU), albumin index and yolk index of the USDHSBM fed group in growing stage were significantly superior (p<0.001) to other groups. In experiment 2, for the 7-week, chicks on the India SBM group gained less (p<0.001) weight than other groups. While daily gain of India SBM chicks was not affected by dietary crude protein level, those of the USDHSBM and Brazil SBM chicks were linearly increased as dietary crude protein level increased from 18% to 20%. The gain per feed ratio of the USDHSBM group was the highest (0.585), followed by the Brazil SBM group (0.568) and India SBM group (0.550) (p<0.01). Therefore, in this experiment, the use of USDHSBM with excellent protein quality and amino acid digestibility could be of advantage to the economic production of layer and broiler.

This study was conducted to investigate the status and prospects of seed quality researches in rapeseed. Rapeseed Quality was mainly related to oil and protein content, fatty acid composition and glucosinolate content. Hence, breeding for improvement of rapeseed Quality has been emphasized as follows: 1) inheritance mode, 2) investigation of germplasm, 3) establishment of analysis technique, 4) establishment of selection method, 5) idealization of cultural technique. The oil quality is determined by its fatty acids. Fatty acids have been determined by gas chromatography. To improve oil quality was emphasized for zero erucic acid, the highest possible linoleic acid and the lowest possible linolenic acid content. Rapeseed meal is not considered as top quality feed ingredient although it has higher protein content and well-balanced amino acid composition. This is mainly because of the presence of considerable amounts of glucosinolates. Thus the reduction of glucosinolate content in rapeseed meal is of great importance. In breeding for meal quality, low glucosinolate lines (plants) were selected and analyzed by gas chromatography and UV-spectrophotometer. Current problems and future researches of rapeseed quality in Korea are 1) improvement of researcher's number and facilities, 2) depression of animal feeding trials, 3) unsatisfied relationship between research and manufacturing and products field, 4) improvement of fertility for yellow and thin seed coat lines crossed between mustard and rapeseed, 5) establishment of new rapid analysing system for rapeseed quality.

This experiment was conducted to evaluate the effects of feeding different levels of lacquer (Rhus verniciflua Stokes) meal on the growth performance, carcass traits, fatty acid profile and meat quality of longissmuss dorsi (LD) muscle in finishing pigs. Pigs (n = 117; Landrace$\times$Yorkshire$\times$Duroc; initial body weight $80{\pm}0.4kg$) were allotted to three dietary treatments and fed lacquer at 0, 2 and 4% of the diet for five weeks. Inclusion of lacquer meal in the diets of pigs had no influence on their growth performance, carcass yield, loin eye area and fat free lean; however, pigs fed lacquer diets had lower backfat (linear, p = 0.006; quadratic, p = 0.004). Pigs fed increasing levels of lacquer meal had lower moisture (linear, p<0.001; quadratic, p = 0.008), crude fat (linear, p<0.001) and crude protein (linear, p<0.001; quadratic, p = 0.002) in LD muscle. The LD muscle of pigs fed lacquer meal had lower pH (linear and quadratic, p<0.05) at 6, 8 and 10 days, and linearly lower thio-barbituric acid reactive substances (TBARS, p<0.01) at 8 and 10 days and water holding capacity (WHC, p<0.05) at 3, 6, 8 and 10 days. The fatty acid composition of LD muscle revealed linearly lower stearic (p = 0.034) and total saturated fatty acid (p = 0.049) with increasing dietary lacquer meal levels. In general, higher lightness, redness and yellowness values were observed in LD muscle of pigs fed 2% lacquer meal on day 0 and subsequently on 3, 6, 8 and 10 days of refrigerated storage. The results of the current study suggest that lacquer meal can be incorporated up to 4% in the diet of finishing pigs without any adverse effects on performance; moreover, improvements in the meat quality during refrigerated storage can be obtained by inclusion of lacquer meal in the diet of finishing pigs.

This Study investigated kindergarten parents' attitude, satisfaction and demand in the school meal service programs (SMSP). The subjects were 2450 parents that their child attended at kindergarten's SMSP from 16 provinces. To com-pared children's eating habits according to their parent age group and residence area, the percentage of regularly breakfast eating were lower in 'below 30 years old' group and large city residence than 'above 30 years old' group and middle and small city residence. And taking breakfast item was partially different pattern according parent age, 'below 30 years old' group and large city child ate more bread and milk as breakfast than Korean style breakfast with steamed rice and soup and side dish. In the prefer types of school meal service, most prefer types of meal service was fully meal service at kindergarten, $79.1\%$ subjects wanted this type. But 'below 30 years old' group's parent answered 'lunch box brings from home' ratio was higher than 'above 30 years old' group. Most parents accepted the present meal cost and $63.8\%$ of subjects was willing to pay more money to improve the quality of SMSP Twenty-six precent parents was responded that no improvement children's eating habit through SMSP. And they answered the key point of SMSP management was 'cooking sanitation'($65.1\%$) and 'nutrition' ($50.0\%$) and they answered the urgent improvement point at SMSP was 'Improvement taste and quality of meal' ($62.6\%$). Kindergarten parents' attitude about catering service as SMSP as not to prefer, but $10.4\%$ of subjects answered that catering service is ideal meal service type in kindergarten and they expected the advantage of catering service was 'convenience of foodservice'($40.7\%$) and 'support foodservice facilities and labor'($32.4\%$) and they also pointed out disadvantage was 'lower in meal freshness'($53.9\%$) and 'sanitation Problem'($51.9\%$).

This study was undertaken to provide basic data for revitalizing the school meal support centers and improving school meals, by analyzing the purchase conditions and satisfaction of food according to an adoption of a school meal service support center. Comparing the purchasing efficiency, convenience to purchase, and higher overall satisfaction was achieved when a school meal service support center was adopted by the local government, as compared to non-adopted school meal service support centers. Therefore, it is considered that the adaption of a school meal service support center is urgently required by non-adoption local governments. Moreover, the stability of food material supplies was also higher in the adopted rather than the non-adopted centers. Satisfaction with the quality of food ingredients was also found to be significantly higher in the adopted centers. These results indicate that if the local government adopts and introduces the school meal support center, inconsistencies observed in the return and exchange processes experienced by the non-adopted centers can be resolved, and food quality satisfaction can be improved. We, therefore, propose the necessity to implement a system for determining reasonable pricing by establishing systematic cooperation among schools, manufacturing entities (suppliers), and the School Meal Service Support Center.

The purpose of this study was to measure patient satisfaction with hosptial foodservices, and thereby identify areas for improvement and provides basic data for the introduction of total quality management into hospital foodservice in the Taegu·Kyungpook area. This survey was carried out on 676 hospitalized patients in 11 hospitals with over 200 beds to determine the quality satisfaction with foodservices. The subjects were 62.4% male and 37.6% female. Sixty-two percent of the subjects were over age 40, 46.7% were only educated to middle school or below, 41.8% were hospitalized for 1 - 10 days. Eighty-seven precent of the subjects did not receive any nutrition education. The expectation and perception grid showed that the high expectation to the low perception items were the seasoning of the meals, taste of the meals, and prompt dealings with meal complaints. The quality satisfaction values of all the attributes indicated a minus. The unsatisfied quality attributes were the opportunity to meet with a dietitian, seasoning of the meals, taste of the meals, explanation of the meals, and prompt dealings with meal complaints. Among the demographic characteristics, age, education, length of admission, and experience with nutrition education produced significant differences in the quality satisfaction scores. In conclusion, it would seem to be desirable that hospital foodservice department introduce selective menus, hygiene education for foodservice employees, standard recipes, quality assurance, and increase the meal rounding of dietitians in the patient foodservice.
