Korea has been free of malaria since the mid-1970s. Since the first malaria case was reported in 1993, the incidence of indigenous malaria has increased yearly, In this study, we planned to understand of malaria outbreak in the northern part of kyonggido. The subjects were a civilians except korean soldiers in the northern part of Kyonggido and the number of civilian malaria cases was 254 in 1997, 677 in 1998, 772 in 1999. The collected rates of Anopheles sinenis in 11 county from May to October were 10.1% to 85.1% and the monthly collected rates at June was highest. The incidence of malaria antibody according to the county was 5.4% in Paju-shi Tanhyun-myun 4.9% in Kapyong-gun Ha-myun, 3.0% in Yonchon-gun Yonchon-eup. etc. At the result of relationship between civilian cases and No. of A. sinenis, envionmental factor were showed high association.

There are lots of waterborne diseases which are caused by pathogenic microorganisms disseminated in contaminated environment. The purpose of this study is to investigate the status of water qualify and in order to investigate the sanitary condition of water purifier in northern part of Gyeonggi-do. We analyzed pathogenic microorganisms and 44 items of drinking water criteria from April to July in 2002. The results were as follows. 1. In 774 samples of water purifier, Pathogenic bacteria(salmonella, E coli O-157, O-26, O-111, shigella, pseudomonas etc.) were not isolated and total coliforms not detected. 2. About 76.5% of the water with purifier are found to be appropriated to the drinking water quality criteria. but 182 samples(23.5%) were without limits of drinking water criteria. 3. In the microbiological examination, 774 samples of purified water showed that 169 samples(21.9%) exceed the range of recommended limits(100 $CFU/m{\ell}$) to the total viable bacterial counts by pour plate method.

The border area between the South and North Korea is considered a stage for promoting Green Détent through the transformation of the Demilitarized Zone into the Green Peace Zone. This paper proposes 'Prosuming-index' composed of items to evaluate the multi-layered nature of industrial and infrastructure projects in the ecological and environmental fields planned in the border area. Based on the prosuming-index, we derived the following four types of potential for Green Detent practice in the border area-first, the Incheon and Ganghwa regions as 'a logistics/human network and agricultural/fishery production area', second, the northern Gyeonggi region as a 'cooperative network area based on the smart technology industries', third, the western Gangwon and the parts of nothern Gyeonggi region, as 'a multiple prosumer's area based on carbon neutral technologies', lastly, the eastern Gangwon region, as 'a transition area from idle or aged infrastructure to green infrastructure through the renewable energy industries'.

In this study, the spatio-temporal characteristics of summer extreme precipitation events in the Republic of Korea are examined based on the daily precipitation data observed at approximately 360 sites of both Automatic Weather Station (AWS) and Automated Synoptic Observation System (ASOS) networks by the Korea Meteorological Administration for the recent decade(2002~2011). During the summer Changma period(late June~mid July), both the frequency of extreme precipitation events exceeding 80mm of daily precipitation and their decadal maximum values are greatest at most of weather stations. In contrast, during the Changma pause period (late July~early August), these patterns are observed only in the northern regions of Geyeonggi province and western Kangwon province as such patterns are detected around Mt. Sobaek and Mt. Halla as well as in the southern regions of Geyeonggi province and western Kangwon province during the late Changma period (mid August~early September) due to north-south oscillation of the Changma front. Investigation of their regional patterns confirms that not only migration of the Changma front but also topological components in response to the advection of moistures such as elevation and aspect of major mountain ridges are detrimental to spatio-temporal patterns of extreme precipitation events. These results indicate that each local administration needs differentiated strategies to mitigate the potential damages by extreme precipitation events due to the spatiotemporal heterogeneity of their frequency and intensity during each Changma period.

The occurrence of Rice stripe virus (RSV) has been confirmed in some parts of South Korea. In the current year, this was observed to be limited in the double cropping zones of the southern region. Earlier, RSV occurred largely in the west coast regions of the country, particularly in Gangwha, Gyeonggi-do in 2001; and Buan, Jeollabuk-do and Seocheon, Chungcheongnam-do in 2007. This study was carried out to determine the nationwide extent of RSV occurrence by investigating RSV infestations in different latitudes and altitudes. Result revealed a recent reported occurrence of RSV in the southern region (Milyang, latitude $35^{\circ}$), a reported occurrence in the northern region (Cheolwon, latitude $38^{\circ}$) in 2005, and in the middle northern region of the east coast (Goseon, latitude $38^{\circ}$) as newly confirmed from this investigation. Results also confirmed the occurrence of RSV in a wide range of altitude from the plains (Milyang, 17 m altitude) to the alpine regions (Jinbu, 576 m) including the middle mountains (Sangju, altitude 285 m). The RSV occurrence in Jinbu in the alpine region and at Goseong and most of the northern end regions were confirmed only this year. The results of the present study confirmed that RSV is a fast-spreading disease in rice plant cultivation regions of the entire country.

The main purpose of this study is to address flooding resilient land use management strategy based on the distributional characteristics of storm damage areas in Gyeonggi-do. The employed methods are 1) Exploratory Spatial Data Analysis (ESDA) to understand the spatial patterns of storm damage areas occurred from 2005 to 2009, 2) Local Indicator of Spatial Association (LISA) to examine spatial autocorrelation existed in storm damage areas for the year of 2009. The results show that 1) crop land damage is very sensitive to heavy precipitation, 2) damaged buildings are found in all over the Gyeonggi areas, but relatively more damages are in the regions closed to the City of Seoul, 3) damaged roads-bridges, streams, and reaches are found in mostly rural areas, 4) building and crop land damage occurs mostly in lowlands with different spatial patterns. These findings imply that 1) it will be useful to consider the average distances and slopes of damaged building and crop lands from streams for the decision making of land use management strategy, 2) further management efforts are required in the north, east, and south regions of Gyeonggi areas to prevent roads-bridge, stream, and reach damages, 3) the present land use pattern needs to be carefully investigated by considering the damage clustered areas for the year of 2009 based on watershed and municipality boundaries.

The purpose of this study was to investigate the vulnerability for groundwater contamination at the some cemeteries in Gyeonggi Province. Twenty-eight out of 43 cemeteries in Gyeonggi province were selected for this study. The DRASTIC model was applied to those cemeteries, and the reliance of the model was assessed using the water quality data of the target areas. The DRASTIC model was used for the assessment of the potential for groundwater contamination using hydrogeological factors. Seven factors including depth of water, net recharge, aquifer media, soil media, topography, impact of the vadose zone, hydraulic conductivity of the aquifer were assessed. The DRASTIC index of the study area ranged from 82 to 126 with an average value of $113.99(\pm11.48)$. The DRASTIC index was relatively greater in the northern Gyeonggi province than that in the southern area. The DRASTIC index was similar for the areas with the similar burial rate and burial density. This study demonstrated that burial rate and burial density should be considered along with the 7 basic factors for the evaluation of groundwater vulnerability of the cemeteries.
