The objective of this study is to analyze the properness, effectiveness and sustainability on the large-scale environment-friendly agricultural districts (LEAD). For this, we survey 11 public officers who manage the LEAD. Most of them aware necessities of LEAD project. They have a higher satisfaction and think that the project affect ripple effect and contribution on environment-friendly agriculture. Main performance expected of the LEAD project is a spread of natural circulation agriculture in connection with cultivation and stockbreeding. For continuance of environment-friendly agriculture after the project, it is necessary to find markets of products. Also policy making related with environment-friendly agricultural technique is required. The results of this study show that the LEAD project need a modification based on field and change of agricultural issues.

In 1980s, studies on the river environment and the management techniques to maintain the quality of water achieved actively. From the beginning of 1990s, the concept considering the river ecology and conservation in urban area have been introduced in Korea. Recently, some environment friendly projects on the rivers have been executed and some are under way. Many small rivers in rural areas have been maintained considering landscape and partly ecology. However until the pilot project named Songsam drainage channel project started in 1998, there were no studies and projects on the irrigation and drainage channels considering environment friendly maintenance. Korea Agricultural and Rural Infrastructure Corporation (KARICO) is going to introduce environment friendly and naturally favorable maintenance technique when the new projects to reform the irrigation and drainage channels are planned. Irrigation channel in O-dong project site in Yeomsan-myeon, Younggwang-gun was designed considering environment friendly consolidation and maintenance.

친환경 벼 재배를 위한 효과적인 잡초관리 방법을 제시하고자 호남 및 충남지역에 위치한 친환경 농업단지에서 있는 농가포장을 대상으로 잡초 발생 양상, 관리 실태 및 쌀 수량 등을 조사하였다. 친환경 농업지역의 잡초방제 관리실태는 왕우렁이농법> 오리농법> 쌀겨농법> 자라농법 순으로 감소하였다. 친환경 농법별우점 초종은 왕우렁이농법에서 피, 여뀌바늘, 물달개비, 벗풀, 사마귀풀이, 오리농법에서 피, 물달개비, 여뀌바늘, 자귀풀, 미국가막사리가, 쌀겨농법에서 피, 물달개비, 여뀌바늘, 여뀌, 올방개 등이었다. 친환경 농법별 쌀 수량은 제초제 처리 농가($5.2\;MT\;ha^{-1}$)와 비교하여 오리농법 93%, 왕우렁이농법 91%, 쌀겨농법 92%, 자라농법 78%이었다. 쌀 품위 중 완전립율, 사미, 착색립, 동할미, 피해립 등은 관행재배보다 낮았으며, 단백질, 아밀로스, 지방산은 관행재배와 유사하였다. 친환경 농업지구 관리 문제점은 논토양 정지 불균일, 배수관리 소홀, 냉수재배지 등 지형적 불리한 조건으로 잡초가 다발하거나 병해충 발생 및 도복 등으로 인하여 수량이 관행재배 대비 약 32~79%가 감소되었다. 따라서 논에서 친환경 농법으로 재배를 할 경우 지형적으로 불리한 지역에서 친환경 농법은 배제되어야 하며 균평작업을 통하여 토양 표면을 일정하게 유지시키는 것이 매우 중요한 것으로 확인 되었다.

The arrangement of small streams in rural area, in the past times, attached importance to the prevention of flood damage through the straightening and lining of streams. Recently, the way of small stream arrangement is introducing the idea of water friendly environment or friendly space. As a result, there has been much concern with water favorable river management model which may lead to control flood. However, it is very difficult to develop a model applicable to all types of rivers, since each river has different flow velocity, flow amount and unique ecological characteristics. In this study, photo processing technique, one of landscape simulation methods, has been adopted because it helps to visually express and comprehensively evaluate pre and post scenery and easily applicable. Some important guideline and technique for the planning of small stream landscape arrangement are mentioned in this study. The simulation system for acquiring water favorable space and arranging landscapes needs to develop database which can forecast various types of landscape. It may also be used for the bases of planning and designing river environment arrangement. Computer aided image processing system enables to make selective planning in river environment arrangement. It may also enables to develop the methods for river environment development, ecology conservation, and multipurpose space utilization. Moreover, it makes economic river arrangement by applying river environment arrangement methods relevant to geographical characteristics. There are some limitations in this study, such as shortage of exact investigation on the stream direction and velocity in landscape arrangement. Continuous monitoring and research may be required to develop techniques through the application of computer graphics and digital image processing.

To assess the effects of a proton beam on oyster mushrooms (Pleurotus ostreatus), the genetic diversity and phylogenetic relationships among strains induced by a proton beam were investigated based on a clustering analysis. According to an AFLP DNA polymorphism analysis, the induced strains were divided into four groups that coincided with the dose. When applying proton-beam radiation, the dissimilarity among the induced strains increased when increasing the dose. When using more than 400 Gy, the genetic dissimilarity of the irradiated strains was 46-58%. Thus, evaluating the induced strains using the AFLP technique was effective in revealing the mutation effect of the proton beam.

The objectives of this study were to identify the cause of consumers for purchasing foods from various distribution channels, and to compare with characteristics of consumers by each distribution channel. The distribution channels as the basis of comparison were four types namely, the consumer cooperatives / environment－friendly specialized stores, large retail discount stores, direct marketing and parents / relatives. The researcher developed a questionnaires, and a total of 190 questionnaires were collected and 186 of them were analyzed. The data were analyzed utilizing the SPSS－WIN 12.0K program and major statistical technique were mean, percentage, t－test, Chi－square test, ANOVA. There were differences in the quality perception, demographical characteristics, relationship with rural communities and personal experiences of the consumers according to the distribution channels.

With urbanization in many countries, many pervious areas are being converted into impervious areas. These land use changes cause many negative impacts on runoff and water quality in the areas. Especially runoff volume and peak runoff are increasing with urbanization. In addition to the increased runoff, more pollutant transports to the downstream areas. For these reasons, Low Impact Development (LID) are nowadays being introduced in urban planning. For environment-friendly and economical urban development, the LID Integrated Management Practices (IMPs) are applied in various urban development. However, exact effects on runoff and water quality of various LID IMPs are not assessed with proper LID evaluation technique. Thus, the SWMM (Storm Water Management Model) 5.0 model was slightly modified to simulate the effect of infiltration manhole on runoff and water quality. For comparison of runoff and TSS (Total Suspended Solids) from the study area (26.5 ha), three scenarios were made in this study. It was found that runoff volume, peak runoff, and TSS could be reduced with infiltration manholes and pervious pavements to some degree. Although, there are many limitations in the analysis of LID effects on runoff and TSS, similar trends shown in this study would be expected with site-specific LID IMPs. Thus, it is strongly recommended that various site-specific LID IMPs, such as infiltration facilities, should be applied as much as possible for environment-friendly urban planning.

This study was initiated to investigate the applicability of sludge from water or waste water treatment on the crop cultivation. Sludge is generated in the process of water and wastewater treatment process in large quantity. The sludge can cause many environmental problems. we have a many available treatment methods of sludge However, these methods still shortcomings and are not. The composition of typical municipal sludge contains organics and inorganics. The organics components are normally burnt in high temperature and mainly inorganics components are left after thermal treatment process. For the production of artificial media, chabazite was used as additive, and the mixed material was thermally treated in the firing kiln at 800~1,10$0^{\circ}C$ for about 10 minutes. The physical and chemical characteristics of artificial media were analyzed and it showed that the artificial media could be used as a media for plants and soil conditioner for farmland. The concentrations of the toxic heavy metals in the media were lower then those in the soil quality standard for farmland. This study illustrated that the artificial media production process, and introduced how to produce it's possible application as a media for Plant growth.
