This study is to examine the origin of Andong sikhe and to introduce the making process of it. The following facts are found after consulting literature and doing field-work to find out the origin of Andong sikhe. Andong sikhe is a kind of so-sikhe develolped as a sweet beverage, the making process of which is to ferment the mixture of boiled rice, radish slices, and red pepper extract with malt liquid. So-sikhe is made by fermenting with malt the mixture of boiled rice, radish slices, red pepper powder and flavorings such as a shallot, a garlic and salt, and o-sikhe is made by adding fish to the ingredients used to make so-sikhe. So-sikhe is distributed on the coastal areas of the East Sea and the inland areas adjacent to them as o-sikhe is. It is presumed that so-sikhe was introduced to Korea by the same way as o-sikhe was introduced eastward from the regions around Thailand by sea. It is also presumed that Andong sikhe has been developed into its present type after the second half of the 18th century when red pepper was introduced to Korea and then widely used.

Though hydrogen peroxide ($H_2O_2$) causes a deleterious effect to cells with its reactive oxygen species resulting in cell death, S-allyl cysteine (SAC, a bioactive organosulfur compound of aged garlic extract) has been known to have a cytoprotective effect. Few reported profiles of gene expression of $H_2O_2$ and SAC treated human cord blood derived mesenchymal stem cells (MSC). This study revealed changes in the profile of twenty-one genes grouped by oxidative stress, antioxidant, cell death, anti-apoptosis and anti-aging by quantitative real time PCR. A concentration of $100{\mu}M$ of SAC or $50{\mu}M$ of $H_2O_2$ was applied to MSC which show moderate growth and apoptosis pattern. $H_2O_2$ treatment enhanced expression of eleven genes out of twenty-one genes compared with that of control group, on the contrary SAC suppressed expression of eighteen genes out of twenty-one genes except C ros oncogene. SAC decreased expression of oxidative stress genes such as SOD1, CAT and GPX. These results seemed consistent with reports which elucidated over-expression of NF-${\kappa}$B by $H_2O_2$, and suppression of it by SAC. This study will confer basic information for further experiments regarding the effects of SAC on gene levels.

A computer system for crop information was developed using Visual Basic and ArcGIS VBA. The system is operated on ArcGIS 8.3 with Microsoft Access MDB. Landsat +ETM, KOMPSAT-1 EOC, ASTER VNIR and IKONOS panchromatic (Pan) and multi-spectral (MIS) images were included in the system to extract agricultural land use items identifiable at various spatial resolutions of images. Agriculture related data inventories using crop cover information such as texture and average pixel value of each band based on crop cultivation calendar were designed and implemented. Three IKONOS images were loaded in the system to show crop cover characteristics such as rice, pear, grape, red pepper, garlic, and surface water cover of reservoir with field surveys. GIS layers such as DEM (Digital Elevation Model), stream, road, soil, land use and administration boundary were prepared to understand the related characteristics and identify the location easily.

To evaluate the quality of fish extracts with spicy vegetables (garlic, onion and ginger) in suppressing fishy oder, fish extracts of crucian carp, loach, bastard halibut and jacopever were processed at 100 $^{\circ}C$ for 6 hours, and their in vitro and in vivo protein qualities were determined . Protein and total lipid contents were closely related to the degree of discarding floated lipid on fish extracts and the kinds of added apicy vegetables . Boiling (10$0^{\circ}C$) , appeared to improve in vitro protein qualities slightly more than hydrocooking (11$0^{\circ}C$), but those with mild processing tended to result in better protein qualities than high temperature cooking (136-14$0^{\circ}C$). Spicy vegetables did not have remarkable effects on improving in vitro protein quality parameters. Fish extracts with 10% ginger were generally higher in in vitro protein quality than with the other vegetables . In spite of higher in vivo protein digestibility of fish extracts containing spicy vegetables processed under mild conditions(10$0^{\circ}C$), PERs of those extracts were not higher htan those of extranct processed at high temperature.

The effects of water extracts of cow bone(WECB), and crab-shell powders(CSP) on the fermentation of kimchi were investigated. WECB has not a great effects on pH, titratable acidity, ratio of lactic acid bacteria against total microbe, and the number of Leuconostoc and Lactobacilli, but has on sour taste, and flavor and overall taste. The kimchi prepared by adding the 0.03% WECB and 1.5% CSP together showed more effective than the control and CSP-added kimchi in pH maintenance, buffer action ratio of lactic acid bacteria against total microbe. The sensory profiles such as fishy and garlic flavor, crispness and overall taste showed in the control and CSP-added kimchi were improved in the kimchi added no only, and CSP and WECB together.

Lipoxygenase activity in Chinese cabbage was measured at various concentrations of brines. Lipoxygenase activity on linoleic acid substrate was determined by changing the rate of dissolved oxygen consumption. The inactivation of lipoxygenase by salting was increased when concentration of sodium chloride and soaking time were increased. About 60% of enzyme activity was reduced after submerging in 13% brine solution for 5 hr. The addition of calcium chloride (0.7%) reduced about $10{\sim}15%$ of lipoxygenase activity rather than without. Residual activity of lipoxygenase in Chinese cabbage submerged in 13% brine was 20% and about 60% of lipoxygenase was also inhibited by addition of garlic extract.

Eleven functional plant materials were identified via a literature search, and their antioxidant capacity and inhibitory effects on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 cells were tested. Yields from hot water extracts of the materials were the highest (52.10%) in Lycii fructus, and the yields from Phellinus linteus were the lowest (5.7%). The yields of another were 14.50-42.47%. Total phenol and flavonoids contents were the highest in P. linteus. The $EC_{50}$ values for DPPH and ABTS radical scavenging activities were lower than $100{\mu}g/ml$ for Salvia miltiorrhiza, whereas the values for P. linteus, Scutellaria baicalensis, and Paeonia lactiflora were $100-200{\mu}g/ml$. The $EC_{50}$ value for the superoxide anion radical scavenging activity of all the extracts was higher than $300{\mu}g/ml$. P. linteus for the reducing power was shown the highest activity. $Fe^{2+}$ chelating activity was the highest in the Morus alba extract. In an MTT assay, the cell viability of the RAW264.7 LPS-exposed cells was above 80% in extracts of $50{\mu}g/ml$ and above 77% in extracts of $100{\mu}g/ml$ in all the plant materials except Acanthopanax sessiliflorum. NO production in the RAW264.7 LPS-exposed cells showed a 12-fold increase compared to the control. The NO production level of all the extracts was $6.86-26.18{\mu}M$. Notably, $100{\mu}g/ml$ of S. baicalensis extract showed a remarkable decrease in NO production (72%) compared with the control. The potent antioxidant and anti-inflammatory activities of S.baicalensis, P. linteus, S. miltiorrhiza, M. alba, and P. lactiflora suggest that they are potential candidates as functional materials.

This study was carried out to determine the biological activities of Wa-song (Orostachys japonicus) hot water extracts. Four types of extract samples were prepared, including Wa-song, traditional plants mixture [PM; mixture of Baekbokryung (Poria cocos), Changchul (Atractylodis rhizoma), and Sa-in (Amomum xanthoides)], and two different ratio composites of these (mixture of PM and Wa-song extract, 1:1 (v/v); PMO-1 and 1:3 (v/v); PMO-3). Their biological activities were measured using various in vitro assays. Total phenolic and flavonoid contents of PM were higher compared to those of Wa-song, and those of PMO-1 were higher than those of PMO-3. Further, PMO-1 contained higher ABTS and DPPH radical scavenging, reducing power, and nitrite scavenging activities than PMO-3. On the contrary, PMO-3 contained higher tyrosinase and inhibitory activities of MCF-7 and HT-29 cancer cells than PMO-1. According to the results, biological activities of PMOs were significantly higher than those of Wa-song extract and PM in in vitro assays. Therefore, we expect that PMOs could show higher biological activities than Wa-song extract alone in vivo.

The goal of this study was to characterize unrecorded wild yeasts from soils of spices plants fields and further, to elucidate its anti-demential activities and tyrosinase inhibitory activity. Piskurozyma taiwanensis R4-1 (NIBRFGC000502619), Nadsonia starkeyi-henricii R6-2 (NIBRFGC000502618), and Canadida friedrichii M12-6 (NIBRFGC000502615) isolated from soil of garlic field represented newly recorded yeast strains in Korea. Vishniacozyma peneaus I2-9 (NIBRFGC000502617) and Cryptococcus aspenensis I21-1 (NIBRFGC000502616) from soil of ginger field represented also newly recorded yeast strains, and microbiological characteristics of its fifteen yeast strains were investigated. All of these unrecorded yeasts exhibited oval-global shape and have ascospores except Canadida friedrichii M12-6. Piskurozyma taiwanensis R4-1 and Canadida friedrichii M12-6 grew well in vitamin-free medium, and Piskurozyma taiwanensis R4-1 was halotolent growing in 10% NaCl-containing yeast extract peptone dextrose (YPD) broth. After prepared cell-free of the unrecorded wild yeasts, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitory activities as anti-dementia activity and tyrosinase inhibitory activity as whitening activity were determined. Cell-free extract from Canadida friedrichii M12-6 had the highest tyrosinase inhibitory activity of 14.4%.
