It is important to build new irrigation facilities as a countermeasure against new water demand, however the effective use of existing facilities is rather advantageous economi cally and socially.Since many irrigation facilities were constructed before 1960's, the functions of them have been declined and rehabilitation of deteriorated facilities needs great expenses. To operate the irrigation facilities efficiently, the criteria for the maintenance and repair of irrigation facilities should be established according to the importance of structures. for the reasonable evaluation of the irrigation facilities, the Irrigation Facility Inquiry System(IFIS) was developed. The present status of the irrigation facilities are grouped by the type and scale of structures, and the characteristics of irrigation facilities under control of Farmland Improvement Association(FIA) were analysed.

A case study of foodwaste treatment was conducted to compare the impacts of four scenarios: incineration, incineration after biogasification, biogasification followed by composting, and composting. Potential contributions to climate change, acidification, consumption of landfill and human toxicity were assessed. Characterization of human toxicity caused by metals and PCDD/DF was performed by three multimedia fate models. Scenarios with a biogasification process showed lower impact on climate change and human toxicity. The ranking of four scenarios on human toxicity varied depending on the characterization models applied. The steady state models placed high priority on emission of heavy metals to farmland, whereas the dynamic model estimated the emission of PCDD/DF from the incineration process as more significant.

Soil microbial community analysis of farmland soil sprayed with lye in order to use fertilizer in Nigeria was performed. As a control, two kinds of soils not sprayed with lye, located in Eungo and Lagos with general practice in agriculture was selected. Soil sprayed with lye was pH 8.25 through alkalization reaction, while the other soil samples were pH 6.22 and 5.94. Substrate utilization and species diversity index of soil sprayed with lye were low than that of the other soils with the analysis of Biolog ecoplate. As a result of principal component analysis, the relationship between three samples was low. Microbial community analysis was performed by DGGE and most of them were soil uncultured bacterium. Especially, Uncultured Acidobacteria and Uncultured Methylocystis sp., which had been isolated from the rhizosphere of soybean grown in that site were discovered in the soil sprayed with lye.

For last 150 years, blackbirds have moved from their ancestral habitat, the woodland edge, to man-made habitats such as farmland, parks and gardens. These alternative habitats have become one of main blackbird habitats. I compared density of nests and blackbirds in parks, woodland and campus of University of East Anglia to investigate habitat preference. Blackbirds preferred the area covered by $10\sim50%$ of tree or bush patches for their foraging and nesting sites. Blackbirds were more frequently found near buildings rather than far from buildings. Nest characteristics did not affect predation rate and nest preference. This study suggests that man-made habitats may be important for avoiding predation.

To revitalize rural economy and to generate job opportunities in the Korean countryside through the specialized production of high-valued/environment-friendly farm products and the active promotion of green tourism in the farmland-remodelling project sites in 4 main riverside areas, this study developed the regionally differentiated development models of future-oriented agri-business complex. Through two rounds' expert group consulting/checking, related literatures review and similar case-projects benchmarking, a tentative model system was made and corrected, and finally, 6-development types with 24 model complexes proposed.

Based on the critical review of previous new village planning proposals in Saemangeum Farming Zone, this study tried to derive rational and realistic planning/design criteria for new villages firstly through home-and-abroad case studies analysis, interview works on farmers in two villages located in the existing reclaimed farming areas and influential zone analysis from neighborhood villages in old land. By applying these criteria(population structure, farming size, maximum distance between farmland and home, village site size, number of new villages planned) on Saemangeum Farming Zone, basic new village planning framework was proposed finally.

1983년 6월에 일본으로부터 자연농권 동물권에 수입된 3세령의 반umboldt젠귄 4수가 입사한지 일주만에 갑자기 식욕절폐, 원기소침하여 4∼6일만에 3수가 폐 사하였다. 환조의 혈액도말표본에서 성숙적혈구내에 발육단계가 다른 기생체가 확인되었다. 폐사한 동물은 폐장과 심장에서 심한 수종성 변화가 인정되었고 간장과 비장이 종창해 있었다. 각 장기의 조직학적 결사에서 간회, 등장 및 폐장등에서 광범위하게 현저한 세강훈 피계세계의 증식과 활성화가 관찰되었고 이들 세포에서 여러 발육단계의 schizont가 확인되었다. 이상의 관찰보고는 국내에서 조류의 말라리아 유행을 처음으로 기록한 것이다.

This study focuses on the policy priorities for training agro-healing experts. Training agro-healing experts is an important task that should boost local community in rural areas. In order to make an efficient decision making, the study analyses priority of relevant policies using the AHP(Analytic Hierarchy Process) method. According to the results, R&D comes out first. Human Resource Development(HRD), financial support, and the construction of legal system comes after R&D. In R&D, qualifications and guidelines for participants comes out the most significant issue. In the aspect of HRD, it is very important to develop and utilize regional personnel such as unemployed youth and retirees from related fields. As for financial support, funding for educational facilities (i.e. classrooms and farmland for practice) is needed. In case of legal system, it is desirable to introduce the recruiting experts system and qualification system certified by government.

Landscape structure is important to understand a complex patterns and interaction with adjacent habitat in rural area. The aim of this study is to analyze relationship between landscape structure and insect spatial distribution in rural area to suggest applicable possibility of landscape structure as biological indicator. For this purpose, first, four landscape structure criteria such as distance from the forest; density of farmland-forest ecotone; landscape continuity; and field size are selected. Secondly, these criteria are applied to Gangsang-myeon, Yangpyeong-gun where mosaic feature are conserved at various spatial scale. Thirdly, application of landscape structure criteria is verified using correlation with species number, species diversity, and species richness of insect. As a result, it could be suggested that the landscape structure criteria are useful for explaining insect spatial distribution.

In this study we attempted to estimate damage scope such as bridges destruction, farmland deformation, forest damage, etc occurred by typhoon using two digital aerial images for future high-resolution Kompsat-3 applications. The process procedures are followings: First, image registration between time-different aerial images was implemented. In this process one image was geometrically corrected by image-to-image registration. Second, image classification was done according to 4 classes. Finally through the comparison of classified two images the area of damage by flood and storm was approximately calculated. These results showed that it is possible to estimate the damage scale relatively rapidly using high-resolution images.
