The purpose of the study was to investigate how the Cheongwon Organic Life Festival, a rural festival, affects the farmers of the local farms in Cheongju. Based on grounded theory, this study analyzed the objective using a qualitative research program, the Nvivo11 program. The data was collected through in depth interviews from 13 farmers who participated in the Cheongwon Organic Life Festival, and were also residents of Chungcheungbuk-do. The roles of the local festival expected by farmers, were the sale of local agricultural products, local public relations, regional revitalization, a sense of pride as a farmer, exchange of business ideas for sales of agricultural products, and a line of direct communication between farmers and consumers. The farmers who participated in the Cheongwon Organic Life Festival insisted that sales should rise. The results showed that the farmers who participated in the festival felt socially and psychologically stable while participating. The programs at the Cheongwon Organic Life Festival include a concert, hands on involvement, and agricultural sales, which have a direct influence on both sales and attracting visitors during the local festival. Farmers who participated in the Cheongwon Organic Life Festival asked for the improvement of the overall operation of the festival, including the problems with the admission tickets, parking, arrangement of facilities, festival venue, time, and etc. The suggested improvements for the Cheongwon Organic Life Festival focused on the quality certification system of agricultural products, as well as the organic farming of products, thereby to gain trust from the consumers.

Unusual bloom of toxic cyanobacteria in water bodies have drawn attention of environmentalists world over. Major bloom of Anabaena, Microcystis in water storage reservoir, rivers and lake leading to adverse health effects have been reported from Australia, England and many part of the world. These cyanobacterial cells can release intercellular matter like toxin in water and these intercellular matter can increase the concentration of organic matter. Cellysis can occur when algal cells meet the disinfectants like chlorine in water treatment plant and the resultant rising up of DOC(Dissolved Organic Carbon) or TOC(Total Organic Carbon) can increase the formation of disinfection by products. Disinfectants that kill microorganisms react with the organic or inorganic matter in raw water. In general disinfectants oxidize the matter in raw water and the resultant products can be harmful to human. There are always conflict about which is more important, disinfection or minimizing disinfection by products. The best treatment process for raw water is the process of the lowest disinfection by products and also the the lowest microorganism. In this study the cultured cells, Microcytis Aeruginosa(MA), Anabaena Flos-aquae(AF), Anabaena Cylindrica(AC), and the cells obtained in Daechung Dam(DC) whose dominant species was Anabaena Cylindrica were subjected to chlorination. Chlorination oxidizes inorganic and organic compounds and destruct live cells in raw water. Chloroform was analyzed for the cultured cells which were treated with $20mg/\ell$ dose of chlorine. In general chloroform is easily formed when dissolved organic matter react with chlorine. The cultured cells contributes the concentration of dissolved organic carbon and also that of total organic carbon which might be potent precusors of chloroform formed. The correlations of the concentration of chloroform, DOC and TOC were investigate in this study.

With the development of national economy and increase of income, consumers' demand for quality and safe agricultural products have increased and perception on environmental-friendly Farming products has been sharply changing. In other words, consumers increasingly show the tendency to prefer environmental-friendly farming products for considering health and environment protection, despite higher price. The environmental-friendly farming products in Jeonnam Province is still at its early stage, accounting for 1% or so of the total products. Considerable part of environment-friendly farming products, nevertheless, difficult problem to End consumers, thus sold at relatively high prices. To the questionnaire asking their most severe difficulty is about 30.5% for sale. This suggests that strategies for consumption expansion of environment-friendly farming products, including of consumers, confidence, publicity of consumers, should be established to increase the income of environmental-friendly farmers in Jeonnam Province.

This study investigated the removal characteristics of various micro organic compounds by low-pressure nanofiltration membranes comprised of disinfection by products and pharmaceutically active compounds. The experimental removal of micro organic compounds by low-pressure nanofiltration membranes was compared with the transport model calculations, which consist of diffusion and convection terms including steric hindrance factor. The selected molecule from the disinfection byproducts and pharmaceutical active compounds showed a much lower removal than polysac-charides with a similar molecular size. However,the difference between model calculation and experimental removal of disinfection by-products and pharmaceutically active compounds could be corrected. The correlation of Ks with solute radius was further considered to clarity transport phenomena of micro organic solutes through nanofiltration membranes.

The use of plastics in our everyday lives have been drastically increased during the last few decades. However with the usage of commercial plastic products there is a possibility of microplastic consumption, due to the fragmentation of the products. Additionally, the potential for microplastic ingestion may also be increased by using damaged products. Hence, the current study was conducted to understand the potential release of micro/nano plastics and organic matter from damaged teabags. To check the leakage tendency, the amount of damage to the tea bags from 1-10 cm were tested along with temperatures of 25-70℃, and exposure times from 5 min to 1 hr was tested. Release of fibrous micro/nanoplastics, and organic leachate from the damaged teabags were observed to understand the outflow conditions. Results showed that with the increased degree of damage, temperature, and exposure time increased the release of fiberous matter, where the increase of temperature, and exposure time increased organic leachate. Additional analysis confirmed the leachate of nylon polymers into the heated water.

Agricultural income is calculated with producer price, output and management cost. This study compared organic farming with conventional one for agricultural income, producer price and output by items. And then it proposed the method of item selection and crop system from a diversification point of view. The coefficient of variation to producer prices in organic farming was 4.7%, and conventional one was 30.3% because organic products have been produced in a system of contract farming with consumers' cooperative. This result means the price of organic products is stabler than that of conventional price. And agricultural income of organic farming has been generally known more than that of conventional one. However, agricultural gross income of conventional farming was more than that of organic one by 20.3% in 2010. It was caused by output reduction of a few items(fer example; onion, large green onion, potato and young pumpkin) due to freak weather conditions and constant producer price for several years in organic farming. In order to increase agricultural income, appropriate crop selection and system should be introduced to organic farming. A principal crop is the rice plant and 2 subordinate crops are dry crops at bare field and greenhouse respectively. Thus 5 crop systems that agricultural gross income are relatively increased larger among 15 crop systems estimated are rice+ginger+cucumber, rice+ginger+tomato, rice+large green onion+cucumber, rice+sweet potato+cucumber and rice+onion+ cucumber.

The objective of this study is to propose a necessity of alternative certification for low-pesticide agricultural products (LPAP). For this, we conduct a survey consumer and distributor. Most of consumer does not aware an abolition of LPAP. After abolition, they will purchase pesticide-free, organic, conventional, GAP certificated in order. Both consumer and distributor need an alternative certification of LPAP and have willingness-to-purchase. However, it is necessary to make up for the reliability and objectivity on the alternative and to manage a poor certification. The results of this study is meaningful to distribution and consumption of environment-friendly agricultural products.
