This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on blood glucose level of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. The concentrations of fasting and random blood glucose were similar between CO and RG groups. There was no significant difference in blood glucose levels after glucose treatment during the glucose tolerance test between two groups. The levels of $HbA_{1c}$ as the index of blood glucose status, and insulin were similar in two groups. These results suggested that rice germ oil can't reduce blood glucose concentration of non-insulin dependent diabetic mice compared with soybean oil. But we need to investigate the hypoglycemic effect of rice germ oil by changing supplementary level and period.

This study was carried out to investigate the supplementary effects of the rice germ oil compared with soy bean oil on lipid metabolism of non-insulin dependent diabetic mice. Forty diabetic KK mice were fed two kinds of experimental diets with 20% lipid from soy bean oil as a control(CO) and rice germ oil(RG) for 8 weeks, respectively. Diet intake, body weight, organs weights and lipids levels of serum, liver and feces were measured. There was no significant difference in food and water intake, body weight gain and organs weights between experimental groups. But the concentrations of serum total cholesterol and LDL-cholesterol were lower in RG group than in CO group. The hepatic total lipid and total cholesterol levels of RG group were significantly lower than those of CO group. The contents of total lipid, triglyceride and total cholesterol excreted in feces of RG group were higher than those of CO group. These results suggested that rice germ oil can reduce serum total cholesterol and LDL-cholesterol and hepatic total lipid concentration of non-insulin dependent diabetic mice compared with soybean oil due to increasing fecal lipid excretion. But we need to investigate the hypolipidemic effect of this oil by supplementary level and period.

The weaning practice of infants from 5 to 12 months of age in the area of Chunchon, Kangwon-do was studied. Subjects were divided into 2 groups depending on residential area, monthly family income and mother's educational level. Parents of group 1 (n=90) received higher education and more monthly family income than those of group 2(n=32). The family income was significantly higher in group 1 than in group 2. Mother's educational level has been markedly improved over 10 years, which affected the feeding methods before weaning in both groups(P<0.05). Group 1 appeared to be bottle-fed. Bottle-and mixed-feeding were mainly due to lack of breast milk. 95.6% of group 1 and 71.9% of group 2 started weaning before the age of 6 months and only 16.4% were completely finished regardless of the groups. Commercially prepared foods were used more than home-made for first given-supplementary food. 82.2% of group 1 received fruits and 84.4% of group 2 cookies/crackers as their main supplementary foods. As the motivation of onset of weaning, 'for baby's health and nutritional status' was the most common. These results demonstrate that there are distinct differences between these 2 groups in 1) the feeding methods prior to weaning, 2) time of onset of weaning, and 3) main supplementary foods, influenced by mother's educational level, economic purchasing power, or subjects birth order.

This study was designed to examine the effects of Salicornia herbacea L. (glasswort: GW) on hepatic antioxidative enzyme activities in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200-220g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of glasswort powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-GW 10% and N-GW 20% treated groups, STZ-control, STZ-GW 10% and STZ-GW 20% treated groups. The activities of Xanthine oxidase (XOD), glutathione- S-transferase (GST), glutathione peroxidase (GPX), glutathione reductase (GR), superoxide dismutase (SOD) and CAT (CAT) were measured in the homogenates of liver. The activity of CAT was lower in the supplementary group with glasswort compare to the STZcontrol group but it was not significantly different. The activity of SOD was not significant in all of experimental groups. The activity of GR was significantly increased in the normal supplementary group with glasswort, and GPX activity was significantly increased in STZ-GW 10% group compare to the STZ-control group. The activity of XOD was significantly decreased in the all of supplementary groups with glasswort. The activity of GST was significantly increased in the N-GW 20% group and it was significantly decreased in the STZ-GW 20% group. These results show that the supplementation of glasswort may have favorable influence on antioxidative status in diabetic rats and it may be useful for the diabetic complications as functional food.

This study was performed to study the effects of Gastrodiae rhizoma on lipid concentration of serum and liver in rats fed high fat diet. Male Sprague-Dawley rat were randomly assigned to 5 groups such as basal diet only(BDG), high fat diet(HFG) and high fat diet with 5% processed Gastrodiae rhizoma(GRL), high fat diet with 10% processed Gastrodiae rhizoma(GRM), high fat diet with 15% processed Gastrodiae rhizoma(GRH) supply each of the experimental diets for 6 weeks. Food intake was significantly decreased by both high fat intake and high fat with Gastrodiae rhizoma intake compared with basal diet intake but weight gain was not significantly different from each groups. Liver weights were significantly lowered by Gastrodiae rhizoma intake compared with high fat intake. In the serum, total cholesterol was not significantly different with each groups, but triglyceride level was significantly lowered by Gastrodiae rhizoma intake as compared with control. In the liver, lipid levels inceased with the Gastrodiae rhizoma intake, but total cholesterol and triglyceride levels were not significantly different with control. These results showed that dietary Gastrodiae rhizoma as supplementary food may decrease triglyceride in the serum.

A amphipod, Leptocheirus plumulosus was exposed to Ag contaminated sediments to evaluate relative importance of various uptake routes (sediment, porewater, supplementary food) for Ag bioaccumulation in sediment-dwelling marine invertebrates. Additionally, influence of AVS (acid-volatile sulfide) on the partitioning of Ag to porewater and on the Ag bioavailability was determined to evaluate the utility of AVS criteria for the management of metal contaminated sediment. The experimental sediments were spiked with 4 levels of Ag (0.1-3.3 ${\mu}$mol Ag/g) and AVS concentrations were manipulated to 40 or <0.5 ${\mu}$mol/g, then equilibrated for >2 months to allow pore water/particulate distributions similar to nature. A L. plumulosus was incubated in the contaminated sediments with overlying water for 35d. During the exposure, the amphipods was fed with supplementary food ($TetraMin^{(R)}$) with or without Ag contamination. Following exposure, tissue Ag in L. plumulosus was strongly correlated with the weak acid extractable Ag in sediments ($r^{2}$=0.87, p<0.001). The ratio of AVS to Ag-SEM (Ag extracted simulaneouls with AVS) had a strong influence on porewater Ag concentration, consistent with previous studies. However, Ag bioaccumulation in L. plumulosus was not influenced by AVS concentrations. The amphipods fed Ag contaminated food took up ${\sim}$ 1.8 X Ag accumulated by the amphipods fed uncontaminated supplementary diet. The result suggests that the benthic invertebrates exposed to metal contaminated sediments would accumulate metals largely via ingestion of contaminated sediments and food, with minor contribution from dissolved sources of porewater and overlying water.

The application of fertilizer P to Desmodium intortum at 40, 60 and 100 kg/ha resulted in the P content of the legume regrowth being 0.10, 0.13 and 0.16% on a dry matter basis. When the forages were fed alone to sheep in metabolism pens the corresponding voluntary intakes by sheep of the three forages were 27.3, 42.7 and $54.3g/W_{kg}{^{0.75}}$, respectively. Provision of additional P by rapid infusion into the rumen each morning before any fresh food was offered depressed the voluntary intake of all three feeds. It is suggested that the adverse effect of supplementary P was probably caused by an induced deficiency of either Ca or Mg and led to a reduction in microbial activity in the rumen.

This study was developed a multi-step process of functional jungkwa preparation from jujube fruits to prepare a new processed food, and investigated on the quality of jujube jungkwa. The weight of jujube fruits notably increased during the second processing, compared with jungkwa prepared from dried jujube fruits using an osmosis drying treatment. The weight of jungkwa produced in the second processing step was less than those in the first step. The Hunter values (L, a, b) of dried jujube fruits after the first processing were less than those of control jujube fruits. The L value did not change after the second processing of jujube jungkwa, but the a and b values were markedly decreased. However, the Hunter values did not change during the third processing step. The moisture content of dried jujube fruit, and dried fruit treated by supplementary drying (DDJF) was 37.74 and 35.93%, respectively, and that of dried fruit treated by osmosis drying was 40.42%. The moisture content of dried jujube fruit after the second processing decreased by 2-10%, and by 4-10% after the third processing. The reabsorption ratio of jujube jungkwa after the second processing was 16.93%, and that of jungkwa produced from osmosis-dried fruit 24.81%. The strength and hardness of dried jujube fruit treated with supplementary drying (DDJF) were higher, at 3 and 2, respectively, compared to the values of dried jujube fruit. The rheology of jujube fruit and jungkwa did not change during the second processing. The color, glossiness, acceptability of appearance, flavor, and overall acceptability of dried jujube fruit treated by osmosis drying as the second processing step were somewhat higher than those of fruit processed by other methods. The scores for appearance, flavor, chewiness, after taste, and overall acceptability of dried fruits treated with supplementary drying as the third processing step were somewhat greater than those of fruit prepared by other means. Accordingly, we have developed a process for preparation of jungkwa from dried jujube fruit treated by supplementary drying and osmosis drying as the second and third processing steps.

This study examined the differences of importance and performance perception level among the food & beverage festival attributes of visitors participating 'Daegu Chimac Festival' and also conducted importance-performance analysis (IPA) of food & beverage festival Attributes. The results were as follows: firstly, food & beverage festival attributes were grouped into four factors such as 'sanitation environment', 'food taste and variety', 'food quality and supplementary service' and 'food purchase convenient.' Secondly, the 4 factors and 21 items of festival attributes showed statistically significant differences in their levels of importance and performance. Finally, results of the questionnaire survey of 322 visitors at '2018 Daegu Chimac Festival' indicated that 'food purchase convenient' and 'food taste and variety' were important to visitors and had high performance. Although attributes related to 'food quality and supplementary service' had an low importance and low performance, and also 'sanitation environment' had an low importance and high performance in the IPA results, they were identified as the key determinants affecting food & beverage festival' success.

This study developed learning content and web pages providing information on Health/Functional Food (HFF) for consumers who come across information indiscriminately from a variety of advertising media such as the Internet and TV. After coming to an understanding of the current situation through literature review and fact-finding, we collected information and commercials on HFF that are exposed to consumers. Focusing on advanced countries such as the U.S. and Japan, we examined the current status of consumer education programs, especially in terms of HFF industry. Further, we referred to the guidelines for consumer education provided by the U.S. Food and Drug Administration and monitored the information from a web site that sells dietary supplementary products in the U.S. In addition, we surveyed consumer information on foods for special health use provided by the Japanese National Institute of Health & Nutrition, and investigated a DB of raw materials of function food (functionality/safety documents). Upon a literature review, the 13 functions of HFF were classified. As a result of conducting interviews with consumers, we developed content that was fit for consumers' perspectives. Through this research, we established a web page to enable people to search for information by function and then by raw material. After searching for information by raw materials, searching products by raw materials can be done in cooperation with E-marketplace. Subsequently developed content and education programs were offered on an HFF web page, which has been in operation since 2005. Therefore, it is expected that appropriate information on HFF will be available.
