This study aims to analyze the effects of the Agricultural Ecological Environment Program, the first agri-environmental policy in Korea. To this end, as Janghyeon in Boryeong City and Hwaam in Cheongyang County were set up as experimental group. And similar to these villages nearby, Hwangryong in Boryeong and Gideok in Cheongyang have been set up as the control group. It compared and analyzed the farms' level and structure of awareness. The main results of the study can be summarized as follows. First, the Agricultural Ecological Environment Program improved the awareness of safe agricultural product cultivation and agricultural ecological environment stabilize. However, the contribution to the formation of rural community has not been statistically significant. Second, it was found that the farms clearly distinguish and recognize the safe agricultural products cultivation, the agricultural ecological environment stabilize, and the formation of rural community. On the other hand, it was found that the control group that did not participate in the agricultural ecological and environmental program was confused on the recognition of three things or did not recognize them. To summarized, the future agri-environmental policy can be grafted onto regional development policy. So, the areas of agri-environmental policy should include both agriculture and rural. In addition, the scientific discipline and movement approach should be all used also in the method of approach.

BACKGROUND: The Ministry of Agriculture, Food and Rural Affairs is promoting agri-environment conservation program to induce farmers to participate in agricultural environment improvement and conservation activities. However, assessment tools based on scientific evidence are needed to determine the effectiveness of the program objectively and quantitatively. Therefore, this study was performed to develop plant indicators in order to efficiently evaluate the effects of the agri-environment conservation program promoted by the Ministry of Agriculture, Food and Rural Affairs. METHODS AND RESULTS: The survey was conducted in five regions (Hampyeong, Boryeong, Mungyeong, Hongseong, and Sangju) participating in the agri-eonvironment conservation program. In each region, twenty paddy fields were investigated (ten paddy fields included in the program and ten paddy fields not included in the program). A total of 231 taxa vascular plants were identified in the paddy fields that were included in the agri-environment conservation program, and a total of 177 taxa were identified in the paddy fields that were not included. The average species number occurred on each field was 55.8 taxa in the fields included in the program, and 35.0 taxa in the fields not included in the program. The difference in occurring plants between two groups was found to be more higher in perennial plants than in annual plants. We selected the six groups as indicator plants through five criteria such as perennial plants and broadly occurring species, etc. to verify the effectiveness of the agri-environment conservation program: Taraxacum spp., Ixeris spp., Viola spp., Platago spp., Calystegia spp., and rare and endagered species. There was a high positive correlation between the score calculated using these indicator plants and the total number of plants species. CONCLUSION: This study suggests that it is possible to evaluate the agro-ecological environment by using indicator plants. The selected indicator plants can be effectively used to verify the effectiveness of projects such as agri-environmental conservation programs in the future.

Insect fauna in adjacent areas of Demilitarized Zone (DMZ) in Korea was surveyed seasonally in $2001{\sim}2003$. The survey area was divided into 3 regions (eastern mountain, middle inland, and western coastal regions) in accordance with administrative districts and topography. Sampling methods such as sweeping, sieving, beating, brushing and suction were used depending on the environmental and military conditions. Total 361 genera and 437 species of 116 families belonging to 14 orders were identified. Among these, 46 species were new to insect fauna of DMZ areas. Species richness was the highest in the eastern mountain region. Numbers of habitat-common and -specific species were 96 (22%) and 195 (47.2%), respectively. The insect species community similarity was highest (0.64) between eastern mountain region and western coastal region. Insect orders showing high species richness were Coleoptera (38.9%), Lepidoptera (19.2%), Orthoptera (9.4%), and Hemiptera (9.2%). These results will be useful information for study of history on the change of insect fauna and future conservation in DMZ areas.

The decrease in the farming rates of agricultural produce importing countries has led to concerns over stable food supply and food safety and this situation demands a change in awareness on agricultural problems arising from the depletion of natural resources and environmental destruction. To preserve agriculture, importing countries are emphasizing the various roles of agriculture in order to revive its multi-functional aspects. It is obvious that differentiated strategies are needed to create values from agricultural production, and a liberal arts education can play an important role in making these strategies. However, training programs for future agricultural CEOs of the Korea National Agricultural College(KNAC) attaches too much importance on production skill and management rather than focusing on a liberal arts education. On the other hand, Poolmoo Ecological Agriculture Course carried out by Poolmoo Agriculture Technical High School located in Hongseong-Gun, Chungnam Province (which puts a high value on ecological fanning) gives more weight on a liberal arts education, taking up more than 50% of the curriculum. Also, the National Farmers Academy in Japan which reformed its whole system in 2008, has started various liberal arts educational programs. The Academy fosters creative agricultural management, attractive rural development enhancing a comfortable rural life and educates on the future of Japanese food and international environment. It is expected that the ecological and cultural roles of farming will grow in the future. So, what the KNAC needs is to increase its liberal arts educational programs and various cultural experiences in its educational curriculum to promote agricultural marketing with cultural knowledge and sensitivity.

Eutrophication processes of aquatic environment are strictly correlated with the concentration levels of nitrogen, phosphorous, organic matter and biological parameters such as phytoplankton and chlorophylla (Tremel, 1996; Burns et al., 1997; Young et al. 1999; Wei et al.,2000). Accordingly, the monitoring and evaluation of these factors will provide useful information about the health of aquatic ecosystem. However, the traditional types of auqatic chemistry analysis and ecological monitoring of phytoplankton are time-consuming, costly, and further resulting in secondary pollution due to the use of reagents. NIR (near-infrared) spectroscopy, as a rapid, non-destructive, little sample preparation and reagents-free technology (Hildrum et al., 1992), has been extensively applied to the characterization of food (Osborne and Fearn, 1988), pharmaceutical (Morisseau and Rhodes, 1995) and textile materials (Clove et al.,2000). Currently, NIR technology has been used indirectly in inferring lake water chemistry by two approaches, suspended (Malley et al., 1996) or seston (Dabakk et al., 1999), and sediments (Korsman et al., 1992; Malley et al., 1999). In addition, the evaluation of trophic state and the identification of the key factors contributed to the trophication are the key step to restore the damaged aquatic environment. Moreover, an understanding of the factors, which regulate the algal proliferation, is crucial to the successful management of aquatic ecosystem. In the paper, NIR technology will be used to study the environmental factors affecting the algal proliferation in combination with the trophic state index and diversity index. This novel developed system can be applied in monitoring and evaluating allopathic water environment and provide real time information services for the aquatic environment management.

This study was conducted with the intention of clarifying the effects of land-use types on a species of ground beetle's richness, abundance, and composition; the study focused on urban landscapes. We also selected the potential bioindicators classifying land-use types; eleven sites were selected from an urban landscape in Korea. Overall, land-use types in urban landscapes did not appear to cause significant decrease in species richness or the abundance of total ground beetle assemblage. According to habitat preferences, several land-use types and distances from the forest significantly affected the species richness and abundance, while the open-habitat species were not affected by these variables. Land-use types were classified into two major groups, forest and non-forest areas, based on ground beetle assemblage; several indicators, such as $Dolichus$ $halensis$ $halensis$ and subfamily Carabinae species, were of particular consideration. In conclusion, environmental change by anthropogenic disturbance can cause different effects on ground beetle assemblages, and forest specialists can be negatively affected.

In the current study, several carabid beetle species were proposed as potential biological indicators for different habitat types (levee, upland dike, hillock, and streamside) of agricultural landscapes focusing on agrobiont species. Synuchus arcuaticollis and Synuchus orbicollis were found in all habitat types, indicating that they are general species for all habitat types. Harpalus eous and Synuchus cycloderus are potential bioindicator species for the paddy levee and hillock habitats, respectively. Amara pseudosimplicidens, Anisodactylus punctatipennis, and Chlaenius ocreatus, which occurred widely, and Bembidion morawitzi, which occurred only in the streamside habitat, are potential bioindicators for the streamside habitat.

Land use pattern in the Wangsuk river watershed was investigated on the bases of physiognomic vegetation maps made from the aerial photograph interpretation and field check. Landscape structure was analyzed using a GIS program supported by ArcView. Landscape structure depended on the geographical position of the river, such as the upper, middle and lower river. Watersheds of the upper and middle rivers were dominated by forests composed of secondary forest and plantation. But agricultural fields dominated that of the middle and lower river. Urban area and agricultural fields increased in from the upper toward the lower river watersheds. In addition to, a transformation of agricultural pattern into an institutional agriculture was characteristic in the middle and lower river basins. Water qualities of the Wangsuk river were usually better in the order of the upper, middle, and lower river, but they were fluctuated according to the site. Such fluctuation would due to self-purification of the river and land use pattern of the watershed as the non-point source. In this viewpoint, a strategy to manage the water quality in the level of watershed is urgently required.

Purpose: The purpose of this study is to suggest a implication and improvement which can provide direction when proposing prospective housing policies which comply the peculiar and changing needs of rural communities. Method: Accordingly this study reviewed for rural housing regulations and policies that appear in the process of developing Japanese Excellent Rural Housing. According to the case study, municipal organizations have implemented independent housing programs base on the Promotion of Rural Residence Act for returning farmers. Result: They provide service to provide returning farmers comprehensive counseling and information about employment, child-rearing and education, housing, and etc. The service program is run by a cooperative way. In addition the Japanese Excellent Rural Housing projects nowadays focus on promoting voluntary establishments of local communities by providing comprehensive plans for local community formation and interaction for harmony between existing residents and returning farmers. In the case of Korea, targeting existing residents and returning farmers for settlement environment in rural areas need jobs, child care, education, and comprehensive housing counseling. In addition, this suggests the need for linkages between the various community programs and residents.
