This study selected Yangpyung as a target site because Yangpyung is a area of high value blessed with well preserved natural resources and beautiful natural scene and where thoughtless development and malformed use of land are in progress under the mask of hotel, accommodations and sales facility which fits the interests of land owner. As for the method used for this study, I inquired into domestic/international instances and the concept of existing environmental indicators and assessment of suitability with a view to establish assessment indicators and pose the concept through theoretical investigation of green-network and to establish green-network. 17 articles of environmental indicators such as aspect analysis, contour, greenbelt, DEM, NDVI, nature conservation area, reservoir and area for the promotion of agriculture were chosen as a actual analysing n data for setting up assessment indicators. From the result of analysis, as anticipated, green zone in Yongmusan areas within Youngmun and Seojong areas were the center of green-network in the wide area green-network in Yangpyung and the restricted area by basin system, road and legal regulation was selected as spot area and finally arable land and reservoir were selected as base which connects core with spot.

In order to investigate the hygienic conditions of potable water in farm area, we examined the hygienic bacteriological and chemical tests of the 159 waters in the farm areas of Kwangjugun, Namyangju-gun, Yangpyung-gun Paju-gun and Hwasung-gun.The results were as follows: 1. Of the 159 waters, the average numbers of standard plate count and coliform were 920 $\pm$ 250ml and 450 $\pm$ 380/100 ml, respectively. The average pH was 6.74 $\pm$ 0.08, KMnO$_4$ consumption 4.18 $\pm$ 0.23 mg/l, turbidity 0.74 $\pm$ 0.08 degree, NH$_3$-N 0.07 $\pm$ 0.02 mg/l, NO$_3$-N 7.76 $\pm$ 0.48 mg/l, total hardness 101.3 $\pm$ 4.7mg/l, chlorine 18.6 $\pm$ 1.3mg/l, sulfate 12.9 $\pm$ 1.0 mg/l, lead 0.036 $\pm$ 0.003 mg/l, manganese 0.017 $\pm$ 0.003 mg/l, zinc 0.064 $\pm$ 0.005 mg/l, and copper 0.010 $\pm$ 0.001 mg/l, respectively. 2. Of the 159 waters, 84 samples (52.8%) were over 100 per ml of SPC or detected coliform per 100 ml water and 63 samples (39.6%) exceed over physicochemical limited criteria for potable water. NO$_3$-N was the primary item among excess contents of potable water in farm areas. 3. The contents of total hardness, chlorine and NO$_3$-N in Hwasung-gun were higher than those in the other regions, but the numbers of SPC and coliform in Yangpyung-gun and Namyangjugun were higher than those in the other regions. 4. The correlationships among many items were highly significant (SPC, Coliform, KMnO$_4$ consumption NH$_4$-N, NO$_3$-N, KMnO$_4$, Total hardness, Chlorine, Sulfate).

Sclerotinia rot of C. japonica caused by Sclerotinia sclerotiorum was observed throught the growing season in the vinylhouse at the Namyangiu, Yangju and Yangpyung areas. The disease was commonly occurred at late autumn after transplanting and continuously increased until spring in next year, The disease was especially severe at the Yangpyung area among three areas. Three isolates of S. sclerotiorum obtained from C. japonica in different geographic areas were evaluated for ability of sclerotia formation and viability under different temperature. Temperature for mycelial growth ranged from 5 to 3$0^{\circ}C$, with optimum temperature at 15~3$0^{\circ}C$. Sclerotia were fewer formed at low temperature, but their size was larger than that at high temperature. Small size of sclerotia was more viable than those of large size at high temperature. Based on the differences in viability of sclerotia, the relative ranks of sclerotia were in order ~2 mm > 3~4 mm > 5 mm~.

For the purpose of determining neurophysiological mechanism of math anxiety, we conducted an EEG measurement for 22 sixth grade elementary students including 11 students with high math anxiety (HMA group), and 11 students with low math anxiety (LMA group). We found that in HMA group, delta wave was significantly generated from the right frontal lobe, and in LMA group, four paths are clearly connected while they perform math tasks (right inferior occipital gyrus ${\leftrightarrow}$ left superior parietal lobule /left middle frontal gyrus ${\leftrightarrow}$ left inferior parietal lobule /left middle frontal gyrus ${\leftrightarrow}$ right inferior parietal lobule / right middle frontal gyrus ${\leftrightarrow}$ right inferior parietal lobule). According to the above results we suggest that math anxiety is related to emotions associated with pain, reduces working memory and has a negative effect on math performance.

In Korea the population of breeding house swallow is continuously decreasing. In this regard this study was conducted to find out the overall population trend during 2001-2005. The areas of urban and rural sites were separated to estimate population. Also the sites in Yangpyung areas were chosen to compare population density between two sites during Mar-Aug, 2006. The house swallow had two breeding periods and I tried to correlated amount of days of incubation and number of eggs in the nest. After egg hatching the homing behavior also was estimated assuming lack of foods takes longer to bring foods back to the nest. This study signified that a long term study should be conducted for population change and spring arrival time due to climate change in Korea.

Sclerotinia rot occurred severely on some vegetable crops grown in Namyangju, Yangpyung, and Yangiu areas in Korea in 2001-2002. The crops infected with Scterotinia sp. were Adenophora remotiflora, Armoracia lapathfolia, Angelica acutiloba, Angelica archangelica, Anthriscus sylvestris, Aster tataricus, Beta vulgaris var. cicla, Brassica campestris var. marinosa, Brassica juncea var. laciniata, Chicholium intybus, Lactuca indica var. dracoglossa, Lactuca sativa var. oak-leaf, Petroselinum crispum, and Phyteuma japonicum. The fungus associated with the disease was identified as Sclerotinia sclerotiorum, based on the morphological characteristics of the pathogen. The symptoms were water-soaked spots that enlarged later and became a watery soft rot. Infected parts became yellow and then turned brown, followed by death of the whole plant. White mycelia developed on the upper petioles and leaves and on the soil where these plant parts lay. Then black sclerotia in variable size and shape formed from the mycelial mass. Pathogenicity of the fungus was proven by artificially inoculating each crop. This is the first report of Sclerotinia rot on the listed vegetable crops in Korea.

Korean society has frequently seen the conflicts between environmentally oriented ideology and development ideology which generally take shape as regional problems. An interesting example is the case of Paldang water resource protection area in Yangpyung-kun, Kyunggi Province. At the area, the rural residents are trying to take regional development by utilizing as much as natural resource in the region, and the central government is trying to make clean water sustained for the public interest of the whole people living within the supplying area of the water resource. Accordingly, the conflict is inevitable. It is the role of environmental movement group that makes us pay attention to this region. Under the present situation regarding environmental protection as a core keyword, the environmental protection groups tend to stand on the side of the central government. That is, those groups let the government consolidate its dominance discourse, which help the resistance discourse of the residents weakened. This basic structure of relationship sometimes touches off the situations of antagonistic confrontation. It is the group for organic fanning movement on the region that is playing a significant mediating role between the two. It has eased severe confrontation, and has persuaded the residents, expecially the farmers, to accept so-called win-win strategies which are related with various kind of organic fanning. The agriculture can be regarded as a win-win action because it is a way of fanning adapted to the protected natural environment. It is taking firm hold in this region as an alternative which can satisfy the ideology of 'sustainable development' or 'sustainability'. It could give us a kind of paradoxical confusion that the strategies of regional development of pro-environment are being carried out in the region where the residents are fighting against the government's strict control of natural environment. The example of this region, however, could show a significant direction for solving the continuous problem of conflict between environmental protection and regional development.
