The purpose of this study were to identify the different farming styles of red pepper growers, to describe their characteristics and to get some implications far planning the agricultural development strategy in the area. The researcher surveyed quantitative and qualitative data through interview with researcher developed questionnaires from selected 99 farmers in Eumsung county, Chungbuk province, Korea. The researcher found the low types of red pepper farming: 'red-pepper-centric middle farmers', 'diversified larger farmers', 'red-pepper-dependant small farmers', and 'small farmers for own use'. Based on the above findings, the researcher could derive some implications as follows. Firstly, the difference of market strategy and marketing efforts among the four farming styles should be regarded as important considerations when planning the agricultural development strategy in Emsung county. Secondly, the cooperatives' red pepper marketing strategies in Eumsung county were focused on the processed red pepper products sold at middle or low priced by big retailers in urban areas. Therefore, the cooperatives should change their view point of quality, if they want to initiate the planning process of 'the production and marketing high quality red pepper'. Thirdly, the major efforts of Eumsung county Agricultural Technology Center (ATC) made efforts on increasing the productivity of red pepper farming, however, the technologies recommended by the ATC for farmers required more cost and labour especially for 'red-pepper-dependant small farmers' and 'diversified large farmers'. The ATC should make efforts to find new technologies for helping 'red-pepper-dependant small farmers' to reduce the use of pesticides and 'diversified large farmers' to use the regional images effectively for marketing their hish quality red peppers.

Leachate from municipal landfill site is known to be hard to treat because it commonly contains various toxic material and heavy metals. In addition, portions of biodegradable organic substances in leachate are decreasing in the course of wastes stabilization, which is one of the critical reason for inefficient biological treatment at the end stage of landfill site operation. So this study was conducted to examine the feasibility of municipal landfill leachate pretreatment using electrolysis. The optimum electrode combination was made. The optimum electrode combination was found to be lead and graphite.

An experimental research was conducted in order to study the treatability of leachate and a combined wastewater of municipal landfill leachate and municipal sewage. The landfill leachate was that of Nanjido landfill site, and the municipal sewage was obtained from Chungnang municipal sewage treatment plant of Seoul. Several sets of bench-scale sequencing batch reactor(SBR) were used as experimental apparatus. Specially investigated items in this experiment were the removal efficiency of substrate and the influence of the hydraulic retention time(HRT). The experiment lasted for about 8 months. The result are as follows ; 1) The characteristics of leachate were pH 7.4∼8.1, BOD 280∼450 ㎎/1, COD 1300∼1350 ㎎/l, T-N 2021∼2110 ㎎/l, T-P 2.7∼3.2 ㎎/l, Cl- 3540∼4085 ㎎/l, and heavy metals are a very small amount. And the characteristics of sewage were pH 6.9∼7.3, BOD 78.4∼129.3 ㎎/l, COD 121.2∼305.0 ㎎/l, T-N 14.9∼36.4 ㎎/l, T-P 1.3∼5.9 ㎎/l. 2) The treatability of leachate alone was not treat well. So for the good treatment of leachate, it w;is necessary to deal with the pretreatment before biological treatment and a combined treatment of municipal sewage. 3) The various contents of the leachate were 5%, 10%, 30%, and 50%, and the removal efficiency of COD was 86.0%, 82.8%, 60.6%, and 31.7%. The maximum content of the leachate which could be successfully treated by SBR in the combined treatment eas 10% of that of sewage.
