Farm economy is getting worse because of the free trade trends in agriculture sector and unreasonable application of market economy principles to agricultural products. And The worldwide issues of environmental pollution as well as want of food, water and energy make human future be anxious. In addition, consumers raise questions in argument about safety of foods produced by traditional farming or imported. So I propose the urban-rural living community movement(URLCM) as an alternative plan for sustainable domestic agriculture. URLCM based on environmentally friendly agriculture and community consciousness will be able to solve many of present issues on agriculture and rural society through incessant interchanges between urban and rural community. This URLCM has to be basically founded on principles of symbiosis-coexistence and life circulation. So those that have to be driven forward arc organizing producers and consumer cooperatives, making environmentally friendly rural region and products, combining with consumer cooperatives, training the participants and so forth.

Benthic pollution assessment based on macrobenthic community structure with environmental variables was carried out at twelve stations during two periods on a presumed pollution gradient in Gamak Bay. Univariate and multivariate methods were applied to investigate structural changes in the benthic communities. A clear gradient of pollution effects on the macrobenthic community was observed from the interior to the exterior of the bay. The community on the northwestern basin was severely disturbed due to a low level of hydrodynamics and a large amount of pollutant input from nearby cities. Exterior regions on the southern basin appeared to have the best benthic environmental characteristics among all stations according to most methods of analysis. Central ridge regions and two stations around the islets in the mouth of the bay exhibited intermediate levels of perturbation when compared to the more disturbed interior and undisturbed exterior regions. Pollution effects on the communities were attenuated at the southern area of the central ridge during spring compared to those of summer, where aquacultural farming was densely distributed. The environmental variables primarily correlated to the macrobenthic community structure were total organic carbon (C), organochlorine pesticides (OCPs), and tributyltins (TBTs), contents found on the surface sediment, as anthropogenic variables indicating organic materials.

This study was conducted to investigate the perception about the construct in the Theory of Planned Behavior using In-depth interview for 24 housewives with elementary school children. Most housewives did not have an intention to buy organic vegetables more in the future than in the present. They showed positive attitudes toward organic vegetables in terms of non-use of pesticides and fertilizers, taste, nutrient content, freshness, mental health, and protection of the environment. They showed negative attitudes toward organic vegetables in aspect of price, credibility of organic vegetables, differences in nutrients, appearance, size, perishability, and accessibility. Children, especially those with diseases, were the most influential persons to their mothers for buying organic vegetables. Housewives' negative attitudes toward organic vegetables were barriers for buying more organic vegetables and they were not willing to overcome these barriers actively. Therefore, government policy and nutrition education to change attitudes is needed to increase consumption of organic vegetables.

The purpose of this study was to analyze the role of perceived market influence, which is an important psychological factor influencing consumer behavior in the market, and explain how consumer beliefs related to the market can affect sustainable consumer behavior. First, this study found that gaps in perceived market influence were statistically significant for age and job. Second, environmental concern, organic food consumption (vegetables and meats), and purchase behavior of organic foods were found to be significantly different by degree of perceived market influence of consumers. The mean values were found to be high for the group having strong perceived market influence. This tendency suggests an association between higher perceived market influence consumers and more environmentally friendly consumer behavior. Lastly, this study used Structural Equation Modeling to analyze the effect of perceived market influence as a moderating variable and mediating variable on the relationship between environmental concerns and consumer behavior toward organic foods. The results show a mediating effect on perceived market influence, but a moderating effect could not be found. This result implies that perceived market influence might indirectly affect consumer behavior when transferring environmental concerns to consumer behavior toward organic foods.

The purpose of this study was to investigate Visitors' satisfaction at Eco-Agriculture/Organic Food Expo held in Uljin in 2005. The questionnaire survey with 1,120 participants was conducted at the venue for three times from July 22nd to August 15th, 2005. The evaluation considered Expo facilities and services, and motives of visit along with demographics of 1,080 valid samples. Evaluation results indicate overall satisfaction level of Expo participation was positive and 63.6% of the respondents showed intention of revisit and/or future visit to agricultural events. Expo facilities and service represented higher satisfaction level, however cost factors such as food and beverage, souvenirs and entrance fee had lower performance levels. The study outcome can help local governments and/or organizers host hallmark tourist events in planning and managing.

Despite the impacts of the climate changes on the pelagic ecosystem, few studies have examined the pelagic-benthic coupling in the adjacent East China Sea and Korea Strait. Therefore, the species composition and abundance of the macrobenthic community, as well as the potential food sources of benthic fauna were investigated in the present study using stable isotope analysis (${\delta}^{13}C\;and\;{\delta}^{15}N$) for suspended particulate organic matter (SPOM), sedimentary organic matter (SOM), phytoplankton, and zooplankton. A total of 157 macrobenthic fauna were collected, and the density of the macrobenthic fauna ranged from 4 to 434 ind./0.25 $m^2$, with an average density of 149 ind./0.25 $m^2$. The density of the benthic fauna increased moving from offshore shelf sites to coastal sites adjacent to the Korea Strait. Cluster analysis showed that the macrobenthic communities consisted of three distinct groups: group A in the Korea Strait, group B in the East China Sea, and group C near Ieodo. The dominant species in group A were the amphipods Photis japonica and Ampelisca miharaensis, followed by the polychaete Scolotoma longifolia. Environmental variables, such as the temperature of the seawater and sediment, and oxygen, and chlorophyll a levels, appeared to affect the structure of the community, suggesting the importance of coupling with the pelagic system. The ${\delta}^{13}C$ values of SPOM and zooplankton ranged from -22.97 to -23.5% and -19.92 to -21.86%, respectively, showing a relatively narrow range(<1%) between the two components. The difference between the ${\delta}^{13}C$ values of SOM and pelagic organic matter was also within 1%, suggesting that the SOM originated from the pelagic system, which is an important factor controlling the macrobenthic community.

낙동강 하구역에서 홍수기 전후에 저서동물군집 영향을 알아보기 위한 조사에서, 저서환경은 대부분 지역에서 사질 퇴적상이 우세하였으며, 일부 수로 지역에서 복잡한 퇴적상을 나타냈다. 홍수기 방류에 의한 공간에 따른 퇴적상 변화는 관찰되지 않았으며, 홍수기 이후 하구역 상부에서 유기물이 소량 증가하였다. 저서생물 종조성은 공간적으로 차이를 보였는데, 홍수기 이후에 배수갑문 근처 지역에서 종조성이 감소하였다. 군집분석 결과는 3개 군집구조가 나타났으며, 하구역 하부에 위치한 사주를 기준으로 공간적 구배를 나타냈다. 사주 상부에는 Sinocorophium sinensis, Magelona japonica, Heteromastus filiformis 등 유기오염 기회종들이 우점하였다. 기회종이 디수 출현한 것은 낙동강 하구둑 주변에 서식하는 저서동물이 방류로 인한 유기물 유입 영향에 따른 것으로 해석되며, 방류로 인한 영향은 방조제 부근에서 사주지역까지 나타났고, 사주 바깥지역은 대량방류로 인한 저서동물의 종조성 변화는 관찰되지 않았다.

Macrobeilthic fauna were collected using a van Veen grab $(0.1m^2)$ to investigate the spatial characteristics of the macrobenthos community at 28 stations near the Nakdong River estuary, Southeast Korea, in September 2001. A total of 203 species were sampled with a mean density of $1,554 ind./m^2$ and a biomass of $252.3 gWWt/m^2$. Annelids were the dominant faunal group in terms of species and density, with 68 species and a mean density of $1,031ind./m^2$, which comprised 33.5% and 66.3% of the total benthic animals, respectively. Based on density, three Polychaetes were dominant Tharyx sp· $(420ind./m^2)$, Lumbrineris longifolia $(143ind./m^2)$, and Sternaspis scutata $(118ind./m^2)$, along with a bivalve Theora fragilis $(129 ind./m^2)$. On cluster analysis, the benthic community was classified into four groups based on the species composition: Group-1 occurred in disturbed areas, Group-II in coastal regions, Group-III in central mariculture grounds, and Group-IV offshore. Environmental factors (mean gain size, organic carbon, and depth) were primarily correlated with the macrobenthos community structure. A benthic pollution assessment based on the macrobenthos community structure showed that Group-I and Group-II were located in a coastal area that had been severely disturbed by construction of Busan new port and various pollutants, Group-III was gradually polluted, while offshore Group-IV was the most stable.

This study compared the levels of North Dakota and South Korean conventional and sustainable farmers' participation in community organizations. The North Dakota data were collected in 1990 from a sample of 568 farm and ranch operators. and the South Korean data were collected in late 1999 and early 2000 from a sample of 147 farmers through interviews and surveys. The data were analyzed using the SPSS ANOV A computer program. The sustainable farmers in both countries were more likely to participate in community organizations than the conventional farmers. Nevertheless, through this comparative study it was found that some differences between two countries exist due to their different cultural backgrounds. Whereas Americans were oriented more to morality and ethics influenced by church, farmers in Korean were more influenced by civil movements. Whereas the reduced tillage farmers in Americans were more likely to be sustainable farmers, the mixed farmers in Korea were more likely to belong to conventional farmers. While individuals in community organizations focused on the economics of agriculture, sustainable farming and farmers' social participation were social matters, which were used to develop sustainable community.
