The anti-adipogenic effect of dongchimi nano juice prepared using a nano-filtering process was investigated by measuring leptin and glycerol levels and the expression of a peroxisome proliferator-activated $receptor-\gamma\;(PPAR\gamma)$ gene as indicators of lipid accumulation or lipolysis. Red pepper powder, seeds of red pepper, garlic, and ginger were added in the preparation of dongchimi. Dongchimi was fermented to reach the optimal fermentation period, followed by nano-filtration in the range of $0.0005\sim0.1\;{\mu}m$. The lactic acid bacteria of dongchimi nano juice were removed completely by a nano-filtering process. Treatment of dongchimi nano juice induced glycerol release in the 3T3-L1 adipocytes and decreased the mRNA expression level of $PPAR\gamma$. These results suggested that dongchimi nano juice may enhance lipolysis and modulate adipogenesis in 3T3-L1 cells.

The purpose of this study was to develop a seasoned Hwangseoke-jeot(a kind of salted and fermented fish) with chitosan having less fishy smell and salty taste. In order to decrease the fishy smell and increase the palatable taste effectively, four types of seasoning were developed, in which minced ginger, garlic and onion were included. In order to improve the color and flavor of seasoned Hwangseoke-jeot, high-quality powdered hot red pepper was also added in all the seasonings. Seasoned Hwangseoke-jeot type 1 had the oil and roasted powder of sesame, which are known to decrease fishy smell and palatable taste, and was the basis of other seasoned Hwangseoke-jeot. Type 2 had the oil and roasted powder of perilla, which also were known to decrease fishy smell and to increase palatable taste effectively. Type 3 had roasted soybean powder and laver to increase savory and palatable taste. It was developed especially for old and young people who like savory taste. Type 4, containing citron syrup, was for the young and children. All the developed seasoned Hwangseoke-jeot samples had better red color and other sensory properies than the control (S-company's seasoned Hwangseoke-jeot), as tested by colorimetry and sensory evaluation. More than 1% (w/v) of chitosan gave an astringent taste to seasoning, so it is recommended not to exceed 1% (w/v) in the seasoning. The developed functional seasonings of jeot would be applicable to other kinds of jeot.

In this study, the experimental method has been investigated using molecular biological way to identify raw materials from seasoned red-pepper sauce which is one of the most popular spices in Korea. 6 kinds of seasoned red-pepper sauces were chosen as a sample containing chilli pepper, garlic, onion as a major ingredient and species specific primers were used for the identification of the raw material of processed food. Selected samples were pre-treated to remove salt (samples were washed with distilled water 3~4 times for desalting), after that, to amplify the extracted genes, whole genome amplification (WGA) kit was performed. Afterwards, PCR products were confirmed through the electrophoresis. As a result, 102, 180, 280 bp of specific PCR products were confirmed for each major ingredients such as chilli pepper, garlic, onion. From this study, the gene extraction method was validated for the identification of ingredients from the spices and it would be applied to distinction of low quality chilli pepper powder including seasoned red-pepper sauce illegally.

Microbiological and sensory qualities of Musaengchae prepared with gamma-irradiated red pepper powder were investigated during storage at $4^{\circ}C$. Total aerobic bacteria in non-irradiated raw materials prior to Musangchae preparation were 6.71 log CFU/g in red pepper powder, 3.39 log CFU/g in radish, 2.21 log CFU/g in scallion, and 2.10 log CFU/g in garlic, respectively. Coliforms(2.15 log CFU/g) were detected only in red pepper powder, and not in Musangchae to which gamma-irradiated red pepper powder. None of pH, Hunter's color value, or sensory properties were significantly affected by addition of irradiated red pepper powder. These results suggest that addition of such powder, after irradiation with less then 10 kGy, could improve Musangchae microbiological safety without changing the sensory or physical qualities.

This study investigated the microbiological and sensory characteristics of Kongnamul muchim stored with gamma-irradiated red pepper powder at $4^{\circ}C$. Total aerobic microbes in raw Kongnamul muchim were 5.72 log CFU/g in the red pepper powder and 2.40 log CFU/g in the garlic used during storage, but were not detected n other raw materials. Coliform bacteria and fungi were found, at 3.11 and 3.48 log CFU/g respectively, only n the red pepper powder. Microorganisms in Kongnamul muchim stored with gamma-irradiated (10 kGy) red pepper owder were not detected over 3 days of storage at $4^{\circ}C$. The pH, Hunter's color value, and sensory characteristics id not change significantly on storage. These results suggest that the addition of gamma-irradiated (less than 10 Gy) red pepper powder could improve the microbiological safety of Kongnamul muchim without changing desirable ensory characteristics.

the Chinese cabbage kimchi was fermented with the various submaterials such as hot pep-per garlic ginger leek green onion fermented anchovy juice and sugar according to the average contents of each submaterial described in the 39 kinds of references. And then the effects of each submaterial and lactic acid bacteria such as L. brevis. Leu. mesenteroides. P cerevisiae and L. plantarum on the content of carotenes were investigated, The major carotene in kimchi was $\beta$-carotene. And also $\delta$-carotene and $\alpha$-carotene were detected. Contents of $\beta$-carotene and total carotene were high in the kimchi containing leek red pepper powder green onion and fermented anchovy juice as a submaterial. But the kimchi containing or omitting the other submaterials were litter affected to the contents of carotene. Contents of $\beta$-carotene and total carotene were high in kimchi fermented with Leu. msenteroides L. brevis and P. cerevi-siae as a starter but was low with L plasntarum.

A crop management system was developed using Visual Basic and ArcGIS VBA. The system is operated on ArcGlS 8.3 with Microsoft Access MOB. Landsat +ETM, KOMPSAT-l EOC, ASTER VNIR and IKONOS panchromatic (pan) and multi-spectral (MIS) images were included in the system to understand what kind of agriculture-related information can be extracted for each images. Agriculture related data inventories using crop cover information such as texture and average pixel value of the crop based on cultivation calendar were designed ,and implemented. Three IKONOS images (May 25,2001, December 25,2001, October 23,2003) 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 also supplied and can be overlaid with images to enhance the understanding the general agricultural characteristics and identifying the location easily.

This paper explores the use of IKONOS imagery of 1 m resolution panchromatic (PAN) band and 4 m resolution multi-spectral (MS) band in the development of agriculture­related data inventories. Three images (May 25, 2001, December 25, 2001, October 23, 2003) were used to obtain temporal distributions in crop cover characteristics such as rice, pear, grape, red pepper, corn, barley, garlic and surface water cover of reservoir with field investigations. The availability and cost problems are expected to solve by KOMPSAT-2 that is scheduled to launch in 2005. The capability of KOMPSAT-2 image for crop and rural water resources management will increase by accumulating temporal data inventories as a database.

The purpose of the paper is to explore the current knowledge on the nutritional evaluation, cholesterol-lowering effect and antitumor activity of kimchi and its ingredients(Korean cabbage, garlic, red pepper powder, ginger and onion). Kimchi contains high contents of nutrients such as vitamins(ascorbic acid, $\beta$-carotene and vitamin B complex), minerals(calcium, potassium, iron and phosphorous), essential amino acids and dietary fiber. Kimch also contains high levels of lactic acid bacteria, allicin, capsaicin, organic acid, phenol compounds, flavonoid and sulfur compounds. The dietary fiber and lactic acid bacteria isolated from kimchi are effective in improving intestinal microflora of human. Isoluble dietary fiber shows anticancer activity, but soluble dietary fiber shows hypocholesterolemic effect. Lactic acid bacteria isolated from kimchi acts as a hypocholesterolemic or anticancer agent. A major ingredient of kimchi is mainly cruciferous and allium family vegetables, which were also reported to prevent cancer and atherosclerosis. It is suggested that kimchi is important not only as one of the traditional fermented Korean food but also as therapeutic agent for carcinogenesis and hypercholesterolemic state.
