The reduction of fishing grounds due to the establishment of EEZ system among China, Japan and Korea together with the depletion of fish resources by pollution of waters and successive reclamation projects along the east and the south coastal lines has made many problems in coastal communities including the decrease of population, the deepening aging phenomenon in the fishery society and the fall of relative income level compared with those of rural and urban residents. Especially, the income level of a fishing household is 90%. of a rural resident and 70% of a urban resident. The income of a fishing household consists of 55% of fishing income, 20% of a agricultural source, 20% of income from non-fishing areas, and 10% of transferred income. Compared with that of a Japanese fishing household which has more diverse income sources such as 62% of income coming from non-fishing areas through being hired in manufacturing firms, etc., that of Korean ones is highly dependent upon fishery and agriculture, so that the diversification of income sources is urgently needed, especially in non-fishing areas. This paper shows that as a model to upgrade fisherman's income level, firstly, it is necessary to enhance the value-added of fishing products through processing and new innovation of distribution process and, secondly, to promote tourism in fishing villages. To ascertain this model, a questionnaire survey to fishermen was carried out and showed that they expressed a strong support for the increase of income by the value-added process through processing and innovative distribution system and the active introduction of tourism in fishing villages. A case study on Gosan cooperative in Jeju was also introduced to identify the rationale of the suggested model and this study proved the validity of the model again. Conclusively speaking, to level up the fisherman's income requires the value- added activities through the introduction of product processing and new distribution system together with the introduction of marine tourism in fishing villages.

Background: American ginseng (Panax quinquefolius L.) and Asian ginseng (Panax ginseng Meyer) products, such as slices, have a similar appearance, but they have significantly different prices, leading to widespread adulteration in the commercial market. Their aroma characteristics are attracting increasing attention and are supposed to be effective and nondestructive markers to determine adulteration. Methods: The aroma characteristics of American and Asian ginseng were investigated using gas chromatography-mass spectrometry(GC-MS) and an electronic nose (E-nose). Their volatile organic compounds were separated, classified, compared, and analyzed with different pattern recognition. Results: The E-nose showed a good performance in grouping with a principle component analysis explaining 94.45% of variance. A total of 69 aroma components were identified by GC-MS, with 35.6% common components and 64.6% special ingredients between the two ginsengs. It was observed that the components and the number of terpenes and alcohols were markedly different, indicating possible reasons for their difference. The results of pattern recognition confirmed that the E-nose processing result is similar to that of GC-MS. The interrelation between aroma constituents and sensors indicated that special sensors were highly related to some terpenes and alcohols. Accordingly, the contents of selected constituents were accurately predicted by corresponding sensors with most $R^2$ reaching 90%. Conclusion: Combined with advanced chemometrics, the E-nose is capable of discriminating between American and Asian ginseng in both qualitative and quantitative angles, presenting an accurate, rapid, and nondestructive reference approach.

Rice(Oryza stiva L.) is a major cereal food providing nourishment to over half of the world's populations and was considered only as a source of energy. However, The recent many researches have been made to suggest that rice may relate to prevention chronic disease and health-promoting properties such as postprandial glucose response, hypocholesterolemic effect and blood pressure-lowering effect. There has been numerous observation supporting that rice has hypocholesterolemic effect. Rice, rice bran, rice bran oil and unsaponifiable matter of rice bran oil reduced plasma cholesterol in rat, hamster as well as human. Components of rice showing hypocholesterolemic effect include dietary fiber(hemicellulose, phytic acid). protein, ${\gamma}$-oryzanol, $\beta$-sitosterol, and tocotrienols. Crapo et al has been studied that the effect of various of starchy foods on the postprandial blood glucose and insulin responses in healthy and diabetic humans. The results showed that rice had lower blood glucose and insulin responses compared to potato, bread and dextrose. The different physical forms in the same starch also produce the different postprandial glucose and insulin responses. In recent years, several studies have shown that some components of rice have potent antioxidant activity against Fe$^{2+}$ -ascorbate induced lipid peroxidation in rat liver microsomal membranes. Cell culture and animal studies have shown that some components of rice have inhibitory effect on the growth and proliferation of several types of human cancer cell. It was also reported that the methanol extract of brown rice has antimutagenic activity against various mutagens. In addition, the pepsine hydrolysate from rice protein is reported to inhibit angiotensin converting enzyme activity. GABA (${\gamma}$ - aminobutyric acid) and GABA enriched rice germ is also effective for lowering blood pressure and triglyceride levels.s.

A one-step simultaneous immunchromatographic (OS-ICG) assay using colloidal gold-monoclonal antibody (gold-MAb) conjugates was developed for the rapid multianalysis of aflatoxin B1 (AFB1) and ochratoxin A (OTA) in feed samples. Visual detection limits for AFB1 and OTA were 0.5 and 2.5 ng/mL, respectively, and the results were obtained within 15 min. Matrix interference from the feed extracts was efficiently reduced by appropriate dilution with buffer. Cut-off values of the OS-ICG assay for the feed spiked with AFB1/OTA mixtures (5/5, 10/10, 25/25, 50/55, 100/100 ${\mu}g/kg$) were 10 and 50 ${\mu}g/kg$ for AFB1 and OTA. The comparative analyses of 65 feed samples by OS-ICG, enzyme-linked immunosorbent assay (ELISA), and high performance liquid chromatography (HPLC) showed good agreement. In this study, we confirmed that simultaneous analysis based on immunoassay is possible and it can be used as an on-site multianalysis of AFB1 and OTA in feed, food, and agricultural products.

Supported catalysts are at the heart of manufacturing essential chemical, agricultural and pharmaceutical products. While the longevity of such systems is critically hinged on the durability of metal nanoparticles, the conventional deposition/dispersion techniques are difficult to enhance the stability of the metal nanoparticles due to the lack of control over the interaction between metal-support. Regarding this matter, ex-solution has begun to be recognized as one of the most promising methodologies to develop thermally and chemically robust nanoparticles. By dissolving desired catalysts as a cation form into a parent oxide, fine and uniformly distributed metal nano-catalysts can be subsequently grown in situ under reductive heat treatment, which is referred to ex-solution. Over the several years, ex-solved analog has resulted in tremendous progress in the chemical-electrochemical applications due to the exceptional robustness coupled with ease synthesis. Herein, we describe the ex-solution process in detail which therein introducing the unique characteristics of ex-solved particles that distinguish them from conventionally dispersed nanoparticles. We then go through the history of science regarding the ex-solution phenomena and summarize several major research achievements which embrace the ex-solved nanoparticles to markedly promote the catalytic performances. In conclusion, we address the remaining challenges and the future perspectives of this rapidly growing field.

The yearly consumption of soybean ranged from 1.5 to 1.7 million tons in Korea during 1995-1997 with an increasing trend of annual consumption by 60,000 tons. Gross consumption of soybean was 1.74 million tons in 1997: 1.292 million tons for feed, 0.433 million tons for food and its processing, and 15,000 tons for seed and other uses. Particularly, Korea totally depends upon imports of soybean for feed and oil. Only about $40{\%}$ of soybeans used for food and its processing are supplied through domestic production. Korean markets will be open to foreign agricultural products except for rice in 2004 when the Uruguay Round treaty is completed. According to the Korean Rural Economics Institutes reports, soybean consumption in 2004 is expected to be 1.87 million tons that is higher than that in 1997 by 0.13 million tons. In order to meet the need for soybean, Korean government planned to supply from 0.17 million tons of domestic production plus 1.7 million tons of imports, and also planned to raise the self-supply rate of $9.1{\%}$ in 2004 from $8.6{\%}$ in 1997. According to the USDA reports on international soybean production and consumption, its production is expected to be 150 million tons over the world and the international market prices for soybean will be unstable in 2004. Based on these reports, international soybean trade capacity will be 36 million tons in 2004 that is lower than 39 million tons (accounting for $25{\%}$ of gross production) in 1597. Also, a term-end stock in 2004 is estimated to be 9.6 million tons that is low as compared to 18.6 million tons In 1997, In coping with domestic and international soybean production, consumption and supply, and further possible food crisis, national policies and continuous efforts are necessarily required to promote domestic production and to reduce imports of soybean.
