Nonpoint source pollution has become a concern for water quality in the Han River system, especially during the high runoff events during the monsoon season. The patterns in nonpoint source runoff the relationships with land use, rainfall intensity, and stream nutrients concentrations were surveyed in 19 streams in the Han River watershed. The results show that the magnitude of NPS inputs of nutrients and sediment in the Han River watershed are of a serious concern. In the South Han River watershed, event mean concentrations (EMC) for biochemical oxygen demand (BOD), suspended sediment (SS), dissolved organic carbon (DOC), dissolved total phosphorus (DTP), total nitrogen (TN) Nitrate ($NO_3$-N) and total phosphorus (TP) were $1.94mg{\cdot}L^{-1},\;251mg{\cdot}L^{-1},\;2.75mg{\cdot}L^{-1},\;0.076mg{\cdot}L^{-1},\;2.82mg{\cdot}L^{-1},\;2.40mg{\cdot}L^{-1}$ and $0.232mg{\cdot}L^{-1}$, respectively. In the North Han River watershed, EMCs for BOD, SS, DOC, DTP, TN, $NO_3$-N and TP were $1.34mg{\cdot}L^{-1},\;172mg{\cdot}L^{-1},\;2.63mg{\cdot}L^{-1},\;0.032mg{\cdot}L^{-1},\;1.97mg{\cdot}L^{-1},\;1.55mg{\cdot}L^{-1}$ and $0.148mg{\cdot}L^{-1}$, respectively. The specific export coefficients of nutrient and sediments were much higher than those of other reports. Our study also found that the proportion of agricultural field area was significantly correlated with the EMCs for nutrients. Therefore, efforts to reduce NPS loading must focus on agricultural practices in the watershed. The relationships between land use and nutrient and sediment export found in this study can be used to derive estimates of runoff coefficients for agricultural field and as input data for modeling works and to develop total maximum daily load and best management practices in the Han River watershed.

최근 한국의 주요 사과 수출대상국인 대만의 검역이 강화됨에 따라 국내에서는 검역 및 통관이 상대적으로 수월한 동남아시아를 중심으로 신규 수출 시장을 확대하려는 움직임이 활발하다. 따라서 사과수출연구사업단에서도 해외 시장 개척을 위한 프로모션 행사를 주관하였으며, 직접 사과를 시식한 현지 소비자를 대상으로 한국 사과의 속성별 중요도와 만족도에 대한 설문을 실시하였다. 조사 대상국은 인도네시아, 말레이시아, 싱가포르, 태국 4개국이며, 해당 국가의 소비자 설문조사 결과를 바탕으로 대 동남아시아 한국 사과 수출 확대 방안을 제시하고자 한다. 분석 결과, 첫째, 사과의 가격은 말레이시아를 제외하고 집중관리가 필요한 속성으로 분류되었다. 현지 소비자들이 느끼는 중요도는 높은 반면 현실적으로 한국 사과에 대한 만족도가 낮기 때문인 것으로 평가된다. 따라서 동남아시아 국가별 한국산 사과의 수요계층을 정확히 파악하려는 노력이 요구되며, 사과 수출 시 수출시기별 품종별 합리적인 가격이 설정되어야 할 것이다. 둘째, 내적 요인인 당도와 씹는 느낌 및 외적 요인인 표면, 빛깔 등의 해당 요인 관리가 잘 유지 되어야 할 필요가 있으며, 수확 후 관리 기술의 접목을 통한 품질 개선으로 균일한 고품질의 사과를 지속적으로 생산 수출할 수 있도록 해야 한다. 셋째, 유통요인인 포장의 경우 모든 국가에서 우선순위를 낮추어도 좋다는 결과가 도출되었다. 넷째, 해당 속성의 중요도는 낮은데 반해 만족도가 높은 외적 요인인 모양과 크기의 경우 과잉관리에 대한 개선이 필요하며, 향후, 이러한 요인들을 개선해 나가는 것이 효율적이라는 사실을 알 수 있다. 위의 내용을 종합해보면, 동남아시아 지역은 열대과일이 풍부한 국가들이므로 한국 사과의 합리적 가격과 내 외적 품질 우수성이 동남아시아 수출을 증대시킬 수 있는 중요 요인이라는 결론을 얻을 수 있다. 더불어 지속적인 현지 홍보와 목표 수요계층의 파악 및 수출 자조금 제도의 도입을 통해 대내외적 수출 여건 변화에 체계적으로 대응해 나갈 수 있을 것이다.

In this thesis we aim at analyzing international competitive power of Chinese ginseng in comparison with Korean ginseng and searching policy direction for Korea to compete Chinese ginseng industry. We summarized the research results as follows; First, we examine the structural change of ginseng industry of China. Second, we review the theories for international competitiveness and apply the method of analyzing competitiveness to ginseng industry. Third, we compared the international competitive power of the ginseng industry between China and Korea and found that Chinese ginseng, estimated by Revealed Comparative Advantage(RCA) at about 15, still remains high competitiveness in terms of cost and price but lowering price competitiveness recently. Based on the research results, we suggest export promotion strategies of the Korean ginseng as follows; 1) Korean government should enforce trade cooperation with China so as to register Korean root ginseng an importable medicine. 2) Korean ginseng producer should develop various products such as capsules, powders and etc. according to China's consumer purchasing power and taste. 3) Korean ginseng should be sold as an differentiated commodity so that it will contribute to building consumer loyalty to Korean ginseng, makes market share superior to other cheaper ginseng products in China. 4) In order to be effective brand marketing and product advertisement, there should be established reliable networks to process and distribute Korean ginseng products exclusively.

Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at $4^{\circ}C$. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.

Purpose - Using trade data from 2008 to 2019, this study analyzes the impact of trade facilitation on China's agricultural exports under the RCEP framework using a gravity model based on the level of trade facilitation in 13 RCEP countries. Design/methodology - This study constructs a complete set of trade facilitation index systems, comprehensively measures the trade facilitation level of RCEP member countries, and uses a gravity model to verify the critical role of trade facilitation level in enhancing the trade volumes of RCEP member countries. Findings - We found that trade facilitation has a significant impact on China's agricultural exports as a whole. The effect of each primary indicator varies in magnitude, with finance and e-commerce (F) having the most significant impact, followed by customs efficiency (C) and infrastructure development (1); the institutional environment has no significant effect. Originality/value - This study analyzes the impact of trade facilitation on China's agricultural exports from the perspective of exports, and uses the latest data to study the degree of the impact of trade facilitation in importing countries. Measures to jointly enhance trade facilitation among member countries under the RCEP framework are proposed.

This paper is aimed to study on sales promotion strategies for the increment of farm income by cultivating Boxthron in Chongyang Area. Marketing Survey was done in Chongyang Boxthron market, Kyoung-dong herb market in Seoul. The results are as follows ; Reviewing the Boxthron market prices, the price of direct transaction was the highest one and that of Agricultural Cooperatives was next one, Chongyang market price was lowest one. Therefore, the efforts including exclusive labeling, high class packing strategies of Boxthron with lower pollution would be necessary. The seasonal variation Boxthron prices were lowest in Aug.-Sept., harvesting season, and highest in april-june prices, off-crop season. Farmers have sold 45% of all products in Aug.-Oct. at lowest price and the remaining 15% of that sold in april-june at the highest prices. On account of the above reasons, loan for Boxthron production, government purchasing and storage program of it especially in harvesting season from Aug. to Oct. should be adopted to increase Boxthron producer income. Finally, the strategies for sales promotion, enforcement of government supporting activities including export strategies and the development of new processed products of Boxthron should be propelled considering the products cycle.

This study is to provide a comprehensive overview of the changing vegetable sector of Chinese agriculture and to analyse the competitiveness of Chinese vegetable production. China now produces more than 60% of the world's vegetable supply and that 150 million people are engaged in vegetable production, processing and marketing since the reform of vegetable industry structure started in the late 1980s. As a labour abundant industry, China also features more comparative advantages in the vegetable trade. Although China's vegetable exports still accounts for only 1% of total production, the 5 million tons of export in 2003 makes China one of the largest vegetable players in the international markets. When estimating competitiveness of China's vegetable industry, China's producers' prices for vegetables are founded to be only from 10%~40% of what they are in Korea, while most of China's vegetables have also strong competitiveness in quality. As China joined the WTO in 2001 and expects to increase market share in vegetable trade, the development strategy for Korea's vegetable industry are suggested as follows; 1) focusing on the technology for the growth of vegetable productivity, 2) developing the higher value added vegetable industry through processing, 3) expanding the exported area and leading vegetable varieties.

An experiment was conducted to investigate the effect of niacin supplementation on hepatic lipid metabolism in rabbits. Rex Rabbits (90 d, n = 32) were allocated to two equal treatment groups: Fed basal diet (control) or fed basal diet with additional 200 mg/kg niacin supplementation (niacin). The results show that niacin significantly increased the levels of plasma adiponectin, hepatic apoprotein B and hepatic leptin receptors mRNA (p<0.05), but significantly decreased the hepatic fatty acid synthase activity and adiponectin receptor 2, insulin receptor and acetyl-CoA carboxylase mRNA levels (p<0.05). Plasma insulin had a decreasing tendency in the niacin treatment group compared with control (p = 0.067). Plasma very low density lipoproteins, leptin levels and the hepatic adiponectin receptor 1 and carnitine palmitoyl transferase 1 genes expression were not significantly altered with niacin addition to the diet (p>0.05). However, niacin treatment significantly inhibited the hepatocytes lipid accumulation compared with the control group (p<0.05). In conclusion, niacin treatment can decrease hepatic fatty acids synthesis, but does not alter fatty acids oxidation and triacylglycerol export. And this whole process attenuates lipid accumulation in liver. Besides, the hormones of insulin, leptin and adiponectin are associated with the regulation of niacin in hepatic lipid metabolism in rabbits.
