  • A phase II site investigation and feasibility study was conducted at a military mortar shooting range near the demilitarized zone (Kyunggi, South Korea) to assess the extent of contaminants migration to the nearby Imjin river in which a flood control dam is under construction. The results showed that silty-clay soils around target areas were co-contaminated with heavy metals (Cd, Cu, and Pb) and explosives (HMX, RDX, and TNT). The total amount of contaminant was estimated to be 497.1 kg-RDX, 20.6 kg-HMX, 1.4 kg-TNT, 35.2 kg-Cd, 4,331 kg-Cu, and 5,115 kg-Pb, respectively. Both heavy metals and explosives were almost equally distributed on each soil particle size fraction. Neither subsurface soil samples nor ground water samples showed signs of contamination above the environmental criteria. The major migration route of contaminants was soil particles in surface run-off during rain at which a mass discharge rate of 30.0 mg-RDX/hour was observed.

  • This survey was carried out to obtain an information for the improvement of nutrition and the enlightment of dietary life in a near by area of DMZ during the later part of July, 1981. A total of 50 households were selected from Tonghyun-ri, Yunchun-eup, Yunchun, Gyunggi province. As a results of survey, the average intake of vegetable food was as high as 98% and that of the protein intake of good quality was not sufficient. Generally energy and nutrition intake were higher than the recommended dietary allowances and national nutrition survey data of Korean. There were no remarkable clinical symptoms related with nutritional deficiency on the entire target, but were some clinical symptoms related with vitamin deficiency on the children. The housewives lived at target area have a tendency to like the food which they are sued to eat daily and that food was mostly self-supplyed.

  • Korean vivax malaria had been prevalent for longtime throughout the country with low endemicity. As a result of the Korean war (1950-1953), malaria became epidemic. In 1959-1969 when the National Malaria Eradication Service (NMES) was implemented, malaria rates declined, with low endemicity in the south-west and south plain areas and high endemic foci in north Kyongsangbuk-do (province) and north and east Kyonggi-do. NMES activities greatly contributed in accelerating the control and later eradication of malaria. The Republic of Korea (South Korea) was designated malaria free in 1979. However, malaria re-emerged in 1993 and an outbreak occurred in north Kyonggi-do and north-west Kangwon-do (in and/or near the Demilitarized Zone, DMZ) , bordering North Korea. It has been postulated that most of the malaria cases resulted from bites of sporozoite-infected females of An. sinensis dispersed from North Korea across the DMZ. Judging from epidemiological and socio-ecological factors, vivax malaria would not be possible to be endemic in South Korea. Historical data show that vivax malaria in Korea is a typical unstable malaria. Epidemics may occur when environmental, socio-economical, and/or political factors change in favor to malaria transmission, and when such factors change to normal conditions malaria rates become low and may disappear. Passive case detection is a most feasible and recommendable control measure against the unstable vivax malaria in Korea in cost-effect point of view.

  • 한국전쟁의 결과 한반도의 허리에 해당하는 DMZ 지역은 반세기 이상 인간의 관심에서 잊혀진 공간이었다. 그러나 최근 국 내외적으로 DMZ에 대한 관심이 고조되면서, 오늘날 DMZ를 대상으로 하는 연구는 점차 활발해 지고 있다. 그러나 정작 연구의 대상인 DMZ의 공간적 범위에 대한 연구는 매우 미약하다. 그마저도 선행연구를 분석한 결과 대부분의 연구에서 군사분계선과 DMZ, 한강하구 중립지역, 그리고 NLL에 대한 기술에 있어서 공간적인 오류를 범하고 있었다. 본 연구에서 조사한 결과, 동해안 고성의 명호리에서 서쪽의 임진강 하구에 이르는 군사분계선의 길이는 약 238km(148마일)이고, 군사분계선을 따라 설정되어 있는 DMZ의 면적은 약 $903.8km^2$로 측정되었다. 이는 현재 '155마일 휴전선' 등과 같이 남북을 양분하는 공간을 지칭하는 용어에 대한 재정립이 필요함을 의미하는 것이다.

  • 한국의 비무장지대(DMZ)일원은 남북한의 군사적 완충지대로서의 역할 외에도 중앙정부나 관련 지방정부, 그리고 국민 모두에게 중요한 대상으로 존재한다. 본 연구에서는 DMZ일원의 주요 자원들을 상징적 '비무장지대 내부 면적', '멸종위기종의 수(환경 생태자원 대표)', '판문점(안보 전적자원 대표)', '문화재', '민통선마을', '생태자원'으로 구분하고 초이스모델링 적용을 통해서 각각의 보전에 대한 지불의사액을 추정하였다. 더불어, 응답자들의 지리적 위치가 보전가치에 영향을 주는지를 검증하였다. 연구 결과에 의하면, 20세 이상의 성인 남녀는 1인당 평균 5만 5,000원 이상의 보전가치를 가지고 있는 것으로 밝혀졌고 국가적 총편익은 최소 2조 700억 원으로 계산되었다. 응답자들의 지역적 특성을 고려하였을 경우, 경기도와 강원도에서는 경기접경의 응답자들이 상대적으로 낮은 지불의사액(4만 9,500원)을, 그 외 6대 광역시는 가장 높은 지불의사액(5만 7,500원)을 가진 것으로 확인하였다.

  • DMZ는 1953년 정전협정 이후 설정된 군사분계선의 남북으로 설정된 완충지대이다. 또한 정전협정 이후 철저히 사람의 간섭으로부터 단절된 지역이고, 67종의 멸종위기종을 포함한 2,716종의 야생동·식물이 서식하는 중요한 자연환경보전지역이다. 반면, 향후 남북경협 활성화 시 DMZ에 대한 개발압력은 증가될 수밖에 없기에, DMZ 개발 시 경제적 비용-편익 관점에서의 논의뿐 아니라, DMZ의 생물다양성을 어떻게 평가하고 보존할 것인지와 복구비용 및 예산도 종합적으로 고려해야 한다. 본 논문은 실물옵션 방법론으로 생물다양성의 가치를 고려한 DMZ 관리 모형을 제시하였다. 또한 DMZ의 정치적 리스크 및 지역적 특수성을 모형 안에 반영하여 설계하였다. 실증분석을 통해 불확실성하에서 DMZ 투자경제성을 확보할 수 있는 생물다양성 가치의 임계값(b*)을 도출하였으며, 이때 생물다양성이 주는 편익을 도출하였다. 그리고 민감도 분석을 통해 생물다양성 가치의 임계값에 영향을 주는 요인을 분석하였으며, 이를 바탕으로 DMZ의 지속가능한 개발을 위한 정책적 시사점을 제시하였다.

  • 최근 픽셀기반분류보다 더 많은 정보를 이용할 수 있는 객체기반에 대한 연구가 활발히 진행 중이다. 따라서, 본 연구는 인제군 Demilitarized Zone(DMZ)지역 일원을 대상으로 객체기반 분류기법을 이용한 토지피복분류를 실시하였다. 분류항목은 환경부 기준의 대분류 항목 7개, 중분류 항목 13개로 선정하였고, 사용된 인자는 분광 값의 평균과 표준편차, Grey Level Co-occurrence Matrix(GLCM)의 Homogeneity를 사용하여 감독분류방법 중 최근린기법을 이용하여 계층적 토지피복도를 구축하였다. 구축된 토지피복도를 이용하여 남방한계선으로부터의 거리와 Digital elevation model(DEM)을 통해 지형특성에 따른 분류항목 별 분포 특성을 분석하였다. 객체기반 분류를 위한 최적 가중치는 Scale 72, Shape 0.2. Color 0.8, Compactness 0.5, Smoothness 0.5로 선정하였고, 가중치 선정과정에서 Scale, Shape, Color가 가장 많은 영향을 주었다. 대분류 토지피복분류는 산림, 초지, 시가지의 순으로 각각 약 92%, 약 5%, 약 2%였으며, 중분류 토지피복분류는 활엽수림, 혼효림, 침엽수림의 순으로 각각 약 44%, 약 42%, 약 6% 순으로 분포하였다. 토지피복형태에 따른 분포특성을 보면, 남방한계선으로부터 2km이내의 지역에서 공공시설 지역과 도로의 이용이 높았으며, 남방한계선 6km이상의 지역에서는 논과 밭, 나지의 형태가 많았다. 산림은 표고 600m, 경사 $30^{\circ}$이상의 지역에서는 면적분포가 높았고, 농업지역과 나지, 초지는 표고 600m, 경사 $30^{\circ}$이하의 지역에서 면적분포가 높았다.

  • Several US veterans stationed in Korea have told the press that around 250 fifty-five gallon drums of herbicides, including Agent Orange, were buried at Camp Carroll in 1978. Joint Korean-US Agent Orange investigation and environmental and health studies were started in July 2011. Korean soldiers and military personnel who served in Vietnam during 1964-1973 or near the demilitarized zone in Korea during 1967-1970 were exposed to dioxincontaminated Agent Orange. The joint Korean-US Agent Orange investigation team found that herbicides, pesticides, solvents and other chemicals -not Agent Orange- were buried at Camp Carroll. However, there remains the possibility that Agent Orange was stored and buried at Camp Carroll or other military camps in Korea. Adverse health effects have not been clearly explained despite a number of health studies among veterans in Korea with potential Agent Orange exposure. Although the Korean government has been compensating veterans and military personnel with 18 presumptive-service-connected-diseases and their offspring with three diseases, there are many veterans, military personnel and civilians who require the government°Øs support. The environmental study on contaminated sites and health studies among veterans and civilians were initiated three or four decades after possible Agent Orange contamination and exposure. Several toxic chemicals, including dioxin-contaminated Agent Orange, could remain in the environment and could have hazardous effects on the health of exposed people for more than several decades. Further environmental investigations and health studies are needed to ensure public safety and health, and government support should be guaranteed for people potentially exposed to these toxic chemicals.

  • In Korea, the Demilitarized Zone(Hereafter DMZ) and the vicinity have special importance for a natural ecosystem research. However, We have difficulty in studying this region due to the access control. The purpose of this study is to analyze the landcover and the vegetation status of DMZ and the vicinity using remote sensing and GIS techniques. The site was divided into two regions; less than 2km from DMZ and less than 10 km from DMZ. The analyzed results of this study are as follow. First, the result of vegetation analysis is that the region of South and North Korea are similar in the area less than 2km from DMZ. However, the region of South Korea have good vegetation status than the region of South Korea in the area less than 10km from DMZ. Second, the result of landcover analysis is that the ratio of the landcover of South and North Korea decreased forest, agricultural and grass, built-up, barren area by turns in the area less than 2km from DMZ. However, the built-up area of South Korea increased as much as the forest area decreased and the other areas of North Korea increased as much as the forest area decreased in the area less than 10 km from DMZ. There are some differences in landcover between analyzed result and an existing statistical data. The causes are using one season setellite images, and an existing statistical data with landuse types. The analysis using remote sensing and GIS techniques is the most suitable method to understand the landcover and vegetation status of DMZ and the vicinity. Further studies are expected to overcome the limitation of this study.

  • The inventory list of wildlife species inhabiting or distributing in Gyeonggi Province was made by compiling species data from precedent surveys, 10 national level nature surveys, 1 survey that Gyeonggi-do conducted, and 46 local surveys presented in scientific journals. Total 2,913 wildlife species including 2,041 vascular plants, 39 mammals, 304 birds, 34 herptiles, 145 fish, and 350 benthic macro-invertebrates were listed in the inventory. It explains 47% of nationwide total species in vascular plants, 31.5% in mammals, 58.2% in birds, 65.4% in herptiles, 12.2% in fish. The total number of important species including endangered species, national monuments, national red lists, etc. was 628 species, accounting for 21.6% of all listed species in Gyeonggi Province. More than 90% of endangered bird species, almost half of endangered fish and herptile species were found in Gyeonggi Province. In particular, abundant bird diversity and inhabitation of many endangered bird species were identified in Gyeonggi Province. Species diversity was greater in the northern area adjacent to the Demilitarized Zone and the eastern forest area. The distribution of the important species such as national endangered species was more distinct in these areas, especially in Gapyeong and Yeoncheon Counties. The inventory list compiled in this study implicates the level of management for biological resources and can provide information for policy decisions regarding new survey sites, protection management of specific species and areas, management practices by spatial characteristics. It should be more compiled and updated with survey data to be utilized as basic indices for local biodiversity strategies and management of biological resources.
