Measuring and evaluating the business performance plays a very important role in managing business. It is both because business performance, in any types of industry, can be evaluated and managed properly only when the measurement of its performance is estimated and because its performance can be improved through an efficient and effective management. Therefore it is essential to build up the performance evaluation system to raise management efficiency of food service industry, to reinforce competitive power of food service industry. In this study, investigated the present performance evaluation system situation of the food service industry and introduced BSC as the main conceptional framework for evaluating the performance of the food service industry. Finally, this study discussed the possible method for building a balanced scorecard to the food service industry.

Current food sanitation systems for meat and livestock in Australia ar underpinned by HACCP-based quality assurance. HACCP-based quality assurance programs have been implemented by all australian red meat industry sectors, from 'farm-to-fork'. These quality assurance programs are (along with other quality and food safety considerations) the collection of a series of sanitation steps and strategies that aim to ensure that only healthy, clean livestock are presented for slaughter; those healthy, clean animals enter a clean processing plant; contact of carcase surfaces with potential sources of contamination is avoided; carcase surfaces are decontaminated before chilling; and subsequent growth of potential contaminants is avoided. Prospects for food sanitation systems for meat and livestock in Australia lie largely in enhancing current and applying new sanitation strategies and procedures within our HACCP-based quality assurance framework. Prospects include increased focus on actual (Versus perceived) risks; on-farm/feedlot pathogen elimination; increased implementation of existing (or new) decontamination technologies; and an improved cold chain.

This study was conducted to investigate the effects of weaning behavior on infants' health status. 294 mothers who had infants, aged 4 to 12 months in Seoul, were selected by cluster sampling and answered by the special questionnaires. Result were as follows : 55.1% of mothers had commenced weaning by 3 months of age. Infants eatten commercial weaning food except for infant eatten only home made weaning food were 88.8%. The case that mothers couldn't make weaning food at the home were 56.6% because they didn't know how to cook of weaning food. Cereals were used frequently as infant foods while meat and fish were lesser used. The higher mother's education level had, the higher nutritional knowledge had. Nutritional knowledge was not influenced on selecting the kinds of weaning food. But the higher nutritional knowledge had, the more desirable weaning behavior mother tended to be had. The more desirable weaning behavior mother had, the more infant's health status tended to be improved. Therefore, for the desirable weaning behaviors of mothers and the improvement of infants' health status, nutritional education program including cook method and development of infant food is need.

Lipids and protein were extracted simultaneously from soybean flour by aqeous processing. Extraction yields of lipids and protein were 62 and 68%, respectively, when 120-150 mesh full-fat soybean flour was dispersed in six times of water (w/w) at $40^{\circ}C$ and pH 8. Supplementary treatment for the higher extraction yields such as proteolytic enzymes treatment improved extraction yields of lipids and protein up to 86 and 89%, respectively. Ultrasonification also improved extraction yields of lipids and protein up to 90%. Red and yellow colors of aqeous-extracted soybean oil were slightly darker than those of hexane-extracted oil, but were much lighter in colors than those of Folch-extracted oil.

For the assessment of representative and longitudinal Zn nutriture in South Koreans, Zn, phytate and Ca intakes were determined using four consecutive years of food consumption data taken from Korean National Nutrition Survey Report (KNNSR) every 10 years during 1969-1998. The nutrient intake data are presented for large city and rural areas. Zn intake of South Koreans in both large city and rural areas was low during 1969-1988 having values between 4.5-5.6 mg/d, after then increased to 7.4 (91% Estimated Average Requirements for Koreans, EAR = 8.1 mg/d) and 6.7 mg/d (74% EAR) in 1998 in large city and rural areas, respectively. In 1968, Zn intake was unexpectedly higher in rural areas due to higher grain consumption, but since then until 1988 Zn intake was decreased and increased back in 1998. Food sources for Zn have shifted from plants to a variety of animal products. Phytate intake of South Koreans during 1969-1978 was high mainly due to the consumption of grains and soy products which are major phytate sources, but decreased in 1998. The molar ratios of phytate:Zn and millimmolar ratio of phytate${\times}$Ca:Zn were decreased due to the decreased phytate intake in South Koreans, which implies higher zinc bioavailability. The study results suggest that Zn nutriture has improved by increased dietary Zn intakes and the decreased molar ratio of phytate:Zn in South Koreans in both large city and rural areas.

The purpose of this study was to investigate the effects of micronutrient supplementation on the growth of preschool children in China. A double-blind, placebo-controlled trial was conducted on 156 growth retarded preschool children who were randomly assigned to the following five groups : supplemental control (S-control; n=28); zinc supplementation (＋Zn; 3.5mg Zn/day, n=34); zinc and calcium supplementation (＋ZnCa; 3.5mg Zn ＋ 250mg Ca/day, n=37); zinc, calcium and vitamin A supplementation (＋ZnCaVA; 3.5mgZn ＋ 250mgCa ＋ 200gVA/day, n=28); and calcium and vitamin A supplementation (＋CaVA; 250mgCa ＋ 200gVA/day, n=29). Another 34 children of normal height were selected as a normal control (N-control). Supplementation continued for twelve months. After supplementation, the height gains in the ＋Zn group (7.84cm per year) and the ＋ZnCa group (7.70 cm per year) were significantly higher than that in the S-control group (6.74 cm per year, P＜0.05). The weight gain in the ＋ZnCaVA group (2.55kg per year) and the ＋CaVA group (2.57 kg per year) was also significantly higher than that in the S-control group (2.19 kg per year, P＜0.05). The average number of days of illness in each group taking supplements was lower than that in the S-control group (13 days per year compared with 23 days per year). No significant differences in bone maturity were observed between the groups. In conclusion, in this study Zinc and Zinc ＋ Calcium supplementation improved the height gain, and vitamin A improved the weight gain, in growth retarded preschool children, but these supplements did not affect the maturity of bone. Micronutrient supplementation also lowered the morbidity of these children.

Soy protein isolate was acylated with succinic anhydride and acetic anhydride. The functional properties are markedly improved by acylation of the $\varepsilon$-amino groups. Acylation of the available amino groups shifted the isoelectric point from 4.5 to 4.0 and enhanced the solubility between pH 4.0-6.0. In the 0.03M-$CaCl_2$ solution the solubility of the modified soy protein is much larger than that of the unmodified protein above the isoelectric point. The emulsion properties and foaming properties also improved by the modification and the effects of pH on the properties paralleled its effect on protein solubility. The changes of reduced viscosity with concentration followed Huggin's equation and by modification the intrinsic viscosity of the soy protein increased and the interaction coefficient decreased.

Ngoc Linh ginseng is one of the most valuable endemic medicinal herbs in Vietnam. In this study, Ngoc Linh ginseng callus was fermented by Lactobacillus plantarum ATCC 8014 (at 6, 7, and 8 log CFU/ml) to evaluate the extraction efficiency of bioactive compounds. The post-fermentation solution was spray-dried using maltodextrin with or without Stevia rebaudiana (3% and 6% v/v) as the wall material. Bioactive compounds such as polyphenols, polysaccharides, and total saponins, and L. plantarum viability during fermentation and after spray-drying, as well as under simulated gastric digestion, were evaluated in this study. The results showed that probiotic density had a significant effect on bioactive compounds, and L. plantarum at 8 log CFU/ml showed the best results with a short fermentation time compared to other tests. The total content of polyphenols, polysaccharides, and saponins reached 5.16 ± 0.18 mg GAE/g sample, 277.2 ± 6.12 mg Glu/g sample, and 4.17 ± 0.15 mg/g sample, respectively after 20 h of fermentation at the initial density of L. plantarum (8 log CFU/ml). Although there was no difference in the particle structure of the preparation, the microencapsulation efficiency of the bioactive compound in the samples containing S. rebaudiana was higher than that with only maltodextrin. The study also indicated that adding S. rebaudiana improved the viability of L. plantarum in gastric digestion. These results showed that S. rebaudiana, a component stimulating probiotic growth, combined with maltodextrin as a co-prebiotic, improved the survival rate of L. plantarum in simulated gastric digestion.

In this study, the protective effects of turanose on Saccharomyces cerevisiae (Baker's yeast) were examined during the freeze-drying process to evaluate the feasibility of utilizing turanose as a novel cryoprotectant. The survival rate of the Baker's yeast cells improved substantially with a cryoprotective medium containing turanose in a substitution-dependent manner. In accordance with these survival rates, the yeast cell surfaces became smoother as the turanose content increased. Turanose with skim milk maintained the viability of the Baker's yeast, which improved substantially upon storage at -20℃. Thus, it is thought that turanose will exhibit excellent preservation effects during the distribution of Baker's yeast. Finally, these results suggest that turanose has the potential to be used as a novel cryoprotectant against various microorganisms.
