This study is to measure the length of the Demilitarized Zone and the Military Demarcation Line(MDL) on the Korean Peninsular. For this purpose, maps of the Armistice Agreement Volume II were used. These maps are nine sheets. In order to extract the MDL shown on the map, coordinates were assigned to the scanned image maps using the georeferencing module of ArcGIS based on the sheet line coordinates. The accuracy of the extracted vectors was checked by overlaying them on the maps of the Armistice Agreement Volume II. And I tried to validate these vectors through comparative analysis with vectors extracted from Kim(2007). Vectors extracted from Kim(2007) had errors in the curvilinear parts of the MDL, but the vectors extracted from this study exactly matched the MDL in the Armistice Agreement Volume II. The measured length is 239.42km(148.77miles). This means that the expression '155mile MDL' or '248km DMZ' in papers, reports or mass media has so far been inappropriate. I think this study will be able to provide information on the exact length of the DMZ in studies related with DMZ or in policy decisions by the national and local government. However, it is deemed necessary to verify this result by national organizations such as the NGII(National Geographic Information Institute). After these verification procedures, I hope that the national government will inform the people of the exact length of DMZ and MDL.

Korean War resulted in the fact that Demilitarized Zone (DMZ) on the neck of Korean peninsular was totally forgotten by people for more than half a century. But recently, as the concern in this DMZ has been rising inside and outside of Korea, the researches on this subject have been gradually quickening. However, the practical studies about spatial extent of DMZ are very feeble. Even the analysis of the previous studies shows that the most of researches had mistakes in the spatial description of MDL and DMZ, neutral territory of Han River estuary, and NLL. In this study the length of MDL, stretching till the estuary of western Lim- Jin River in Myung-Ho Ri of Goseong region on East Coast, was measured to be about Z38km (l48miles); the area of corresponding DMZ was proved to be approximately $903.8km^2$ ($907.3km^2$ in the previous studies). Such results show that it is necessary to decide the terms for calling the space dividing North and South Korea, similarly to "155-mile truce line".

This study is a spatial analysis of the boundaries related to the division of the Korean peninsula. The boundary space was extracted by extracting $38^{th}$ parallel and digitizing the map of the Armistice Agreement Annex. The purpose of this analysis was to extract more accurate scope based on the armistice agreement, the appendices, and the UNC regulations and to analyze the wrong information correctly. The range of demilitarized zones was determined by UNC 551-4(2014) and UNC 551-5(2015) to ensure that there is no change in the location of the Southern Limit Line. It also confirmed that the MACHA was excluded in the DMZ. As a result, the area of the DMZ was measured at $889.7km^2$. Also this study identified the interval and number of markers in the MDL and the Han River estuary. It could be confirmed that the interval of markers within the MDL depends on the subject of management. This study is more accurate from the start and can be used as basic data needed in the study and education of DMZ and border areas after verification by public organizations.

DMZ(Demilitarized Zone) created as part of the Armistice Agreement is important zone in the way that historic and eco-cultural value as well as military and political image of this are remarkable. Furthermore, the concern of DMZ has been rising at home and abroad. Even though various studies on this subject have been constantly spurring according to the significance, the practical researches on spatial range of DMZ are very weak. The Purpose of this research is to show the factual spatial extent of DMZ from the mouth of the Imjingang River in the west to the town of Goseong in the east. This study proved the area of corresponding DMZ is approximately $570km^2$ contrary to the previous studies and claims it is difficult to measure the actual length of MDL(Military Demarcation Line) regarded as 155mile in this situation of Korea peninsula.

임진강 유역면적은 $8,138.9km^2$이나 이 중 62.9%인 $5,108km^2$가 군사분계선 이북에 놓여있어 유역특성에 따른 수문량을 분석하는 데 어려움이 있다. 1996년, 1998년, 1999년 및 2011년 임진강 유역의 이상 강우로 인해 약 1조 원의 재산피해와 136명의 인명피해가 발생하였다. 이처럼 국지성 호우의 발생 여부 및 강우의 지역적 편차 등 수문 정보를 예측하지 못하여 상황 대처가 어려운 실정이다. 따라서 미계측 유역이 많은 임진강 유역의 홍수피해 최소화를 위해 예측 강우와 같은 수문 정보의 필요성이 증대되고 있다. 본 연구에서는 임진강 유역 중 미계측 유역이 97%에 달하는 군남홍수조절지 유역에 예측 강우 자료의 적용을 위해, 임진강 유역의 한탄강 유역($2,436.4km^2$)에 대하여 예측 강우자료의 적용성을 평가하였다. 예측 강우 자료는 기상청의 Local Data Assimilation and Prediction System(LDAPS) 자료를 사용하여 선행 시간에 따른 예측 정확도로부터 적용성을 평가하였다.

The Military Demarcation Line(MDL) divided the two Koreas when armistice agreement was signed in 1953, July 27 but there was no regulation for the sea border. Since then, The North has constantly denied the legitimacy of the sea border, which has remained the inter-Korean maritime border. But the armistice agreement has been virtual maritime demarcation line for the avoidance of hostilities on the Korean Peninsula and maintain and manage the armistice system peacefully. Therefore we should strengthen the Korea's sovereignty over the NLL by tightening the effective control.

South Korea is in a dangerous situation where a war between the two Koreas could be triggered at any time based on the MDL (Military Demarcation Line) between the two Koreas due to the inter-Korean standoff over the armistice. Also, unlike the borders of other countries, the border between the two Koreas is the front-line area where people can feel the threat of life that could be triggered by war. Soldiers who work in special areas such as the contact area are not easily accessible due to local conditions, and are less likely to go out, stay out, stay out, or visit, and the working environment is overloaded with vast forests and silence at night, and feel anxious, lonely and insecure because they don't know when any situation will occur near the enemy. Therefore, a great deal of help will be needed to pay attention to soldiers who give up their lives here and perform their national defense duties, and to finish their barracks life safely and faithfully, and support for psychological adaptation of service members in the border areas.

지상강우 관측망을 이용한 강우량 측정의 대안으로서 사용되는 기상 레이더를 활용한 강우량 추정의 경우, Z-R 방정식을 이용하여 반사도를 강우량으로 환산하는 방법을 일반적으로 사용한다. 이때 발생하는 각종 오차는 레이더 장비가 가지는 기계적인 오차뿐만 아니라 Z-R 방정식이 가지는 오차 등이 있으며, 이를 보정하기 위해서 레이더를 활용하여 추정된 강우량에 지상강우량계와 레이더강우량과의 비율인 G/R비를 보정하는 방법을 일반적으로 사용한다. 본 연구에서는 이와 같이 레이더 강우량을 보정하기 위해서 사용되는 G/R비를 산정하는데 미치는 지형적인 효과를 고려하기 위해서 광덕산 레이더 유효범위 100km 내(군사분계선 이북 미포함)의 지역에 대하여 군집분석을 실시하여 크게 산악지역과 평야지역으로 구분하고, 각각 구분된 지역에 대하여 G/R 비를 산정하여 초기추정 레이더 강우량에 곱하는 mean-field bias 보정을 실시하였다. 광덕산 레이더 기상관측소의 유효범위 100km 내의 2007년, 2008년 홍수기(6/21${\sim}$9/20)기간 동안 94개 Automatic Weather Station(AWS)지점에 대하여 크게 산악지역과 평야지역으로 지역화 시키는 방법은 비계층적 군집분석 기법 중 fuzzy-c mean 방법을 적용하였다. 또한 광덕산 레이더 반사도 기본 자료는 차폐영역으로 생기는 반사도 데이터 누락을 보완하기 위하여 0도와 1.5도 sweep 합성 10분단위 uf 자료를 사용하였으며, AWS와 보정이 이루어지는 레이더 격자의 크기는 최대 4km${\times}$4km로 선정하였다. 본 연구에 있어서 검증방법은 지역을 구분하기 전과 후를 AWS 실측 관측값과 절대상대오차, 평균제곱근 오차로써 비교하였다.

The Demilitarized Zone(DMZ) is a buffer zone set between the southern and northern limit lines established after the 1953 Armistice Agreement. It is an important natural environment conservation area where wild species of animals and plants live. On the other hand, the development pressure on the DMZ will increase when the inter-Korean economic cooperation is activated in the future. As a result, DMZ development should consider not only the economic cost-benefit aspects, but also how to assess and conserve the biodiversity of the DMZ, as well as the recovery costs and budget. This paper develope a sustainable DMZ management model under biodiversity uncertainly by using real option approach. The model is also designed to reflect the political risk and regional specificity of the DMZ. Through empirical analysis, I derive the biodiversity threshold (b^*) that can secure the DMZ investment economy under uncertainty. In addition, through the sensitivity analysis, I derive the factors influencing the biodiversity threshold, and suggest the policy implications for sustainable management of DMZ.
