The object of this study is to detect of land-cover change in western DMZ and vicinity. This was performed as a basic study to construct a decision support system for the conservation or a sustainable development of the DMZ and Vicinity near future. DMZ is an is 4km wide and 250km long and it's one of the most highly fortified boundaries in the world and also a unique thin green line. Environmentalists want to declare the DMZ as a natural reserve and a biodiversity zone, but nowadays through the strengthening of the inter-Korean economic cooperation, some developers are trying to construct a new-town or an industrial complex inside of the DMZ. This study investigates the current environmental conditions, especially deforestation of the western DMZ adopting remote sensing and GIS techniques. The Land-covers were identified through the linear spectvral mixture analysis(LSMA) which was used to handle the spectral mixture problem of low spatial resolution imagery of Landsat TM and ETM+ imagery. To analyze quantitative and spatial change of vegetation-cover in western DMZ, GIS overlay method was used. In LSMA, to develop high-quality fraction images, three endmembers of green vegetation(GV), soil, water were driven from pure features in the imagery. Through 15 years, from 1987 to 2002, forest of western DMZ and vicinity was devastated and changed to urban, farmland or barren land. Northern part of western DMZ and vicinity was more deforested than that of southern part. ($52.37km^2$ of North Korean forest and $39.04km^2$ of South Korean were change to other land-covers.) In case of North Korean part, forest changed to barren land and farmland and in South Korean part, forest changed to farmland and urban area. Especially, In North Korean part of DMZ and vicinity, $56.15km^2$ of farmland changed to barren land through 15 years, which showed the failure of the 'Darakbat' (terrace filed) project which is one of food increase projects in North Korea.

A activated carbon (WCAC, waste citrus activated carbon) prepared from an agricultural waste citrus peel material generated in Jeju was utilized for the removal of dimetridazole (DMZ) antibiotics in aqueous solution. The adsorption of DMZ on WCAC was investigated with the change of various parameters such as contact time, dosage of WCAC, particle size of WCAC, temperature, pH, and DMZ concentration. The DMZ adsorption capacity increased with increasing temperature and decreasing particle size. Also it was decreased at less than pH 4 but sustained almost constantly at pH 4 or greater. Isotherm parameters were determined from the Langmuir, Freundlich, Redlich-Peterson and Duinin-Radushkevich (D-R) isotherm models. The isotherm data were best described by the Redlich-Peterson isotherm model. And the adsorption kinetics can be successfully fitted to the pseudo-second-order kinetic model. The results of the intra-particle diffusion model suggested that film diffusion and intra-particle diffusion were occurred simultaneously during the adsorption process. Meanwhile, the thermodynamic parameters indicated that the adsorption reaction of DMZ on WCAC was an endothermic and spontaneous process. The experimental results showed that WCAC is a promising and cheap adsorbent for the removal of DMZ antibiotics.

DMZ (De-Militalized Zone) in South Korea is world heritage area by passage control of human-being for more than 50 years since 1953. Wild flora and fauna in these area have been protected from any development and/or habitat destruction. However, consideration on ecosystem and nature in the area is becoming higher, and demand for development is raising also. We have reviewed any publications, which are surveyed about ecosystem and interview local residents about wildlife inherit there. Totally 51 species have been reported inhabited DMZ belonging to 17 Families, 6 Orders, so far. National monuments in DMZ are following; Asiatic black bear (Ursus thibetanus), Eurasian otter (Lutra lutra), Musk deer (Moschus moschiferus), KOREAN goral (Nemorhaedus caudatus), flying squirrel (Pteromys volans) and spotted seal (Phoca vitalima). These results would be an essential data to establish management strategy and manuals for conserving native ecosystem, native flora and fauna in DMZ, and also using for registering world heritage area under UNESCO.

The Demilitarized Zone (DMZ) of Korea has been crucial not only for its buffering role between two Koreas, but also for the conservation of various resources across its premises. The objectives of this study is threefold. The first objective is to identify major resources that determine economic values of the DMZ and its vicinity. The second and third objectives are respectively to estimate conservation values of those resources using Choice Modeling and to test whether or not respondents living in different geographical locations have significantly different willingness to pay for the conservation. In a very conservative estimation, results showed that Korean adults have about 55,000 Won on average for conserving five major resources : the DMZ area, endangered species, cultural heritage items and sites, the Truce Village, and villages in the Civilian Conroal Zone. This equals the aggregate economic value of about 2,07 trillion Won. Moreover, significant regional differences were found in public benefits from conserving these major resources.

In this paper, we introduce an SDN-based intrusion prevention system for more secure Science DMZ with no performance limits. The proposed system is structured with intrusion-prevention, intrusion-detection, and prevention-decision subsystems which are physically distributed but informationally connected by an SDN interface. The functional distribution and the application of SDN technology increase the flexibility and extensibility of the proposed system and prevent performance degradation possibly caused by network security equipments on Science DMZ. We verified the feasibility and performance of the proposed system over a testbed set up at KREONET.

This study was conducted to estimate population size and investigate habitat characteristics for the conservation and management of Amur goral Nemorhaedus caudatus raddeanus in DMZ (Demilitarized Zone) of Gangwon Province in South Korea from November 2003 to May 2004. The Amur gorals counting were carried out by assistance of military soldiers who guards the southern boundary of DMZ. Four hundred sixty individuals were estimated as total population size in DMZ of Gangwon Province. Deciduous forest, rocky area and coniferous forest were dominant land cover types in habitat of Amur goral. DMZ and its vicinity of Gangwon Province are very important areas for the conservation of this species. It is needed to establish management plan for the conservation of Amur goral and their habitats in DMZ.

The characteristics of vivax malaria epidemics along the demilitarized Bone (DMZ) in the Republic of Korea has been established by the early surveillance data. To further characterize the epidemic, data of civilian patients microscopically diagnosed with malaria from 1995 through 2000 were analyzed in Yonchon-gun (county) . Malaria incidence was greater in male civilians > 30 years of age (p < 0.05). The annual parasite index was significantly higher in those living in the administrative areas (Myeon) traversed by DMZ than those living in Myons not traversed by DMZ (p < 0.05). Analysis according to the distance (4 to 14 km) from DMZ showed that people living in villages close to DMZ had higher annual parasite indices than those living in villages remote from DMZ (p for trend < 0.05). Civilians living in Myeons with plains and located in northwestern part of the county had higher annual parasite indices than those living in hilly Myeons located in southeastern part of the county (p for trend f 0.05). These findings suggest that the contraction of vivax malaria is related with night-time outdoor activities, and that the distance from DMZ is a risk factor. In this area, the flying distance of infected vector mosquitos can explain the annually repeating occurrence of civilian cases.
