Korea has maritime jurisdiction over an area 4.5 times larger than the nation's inland area, but negotiations with surrounding nations on the maritime boundary delimitation have still not been completed satisfactorily. In particular, maritime boundary delimitation has become an important issue in terms of maritime security and resource exploration. Considering national interests, the delimitation of the maritime boundary is essential. However, no system to help the decision-makers involved in maritime boundary delimitation has yet been systematically constructed. Therefore, the aim of this study was the development of a system to support such decision-making. In this study, considerations related to maritime boundary delimitation were investigated through expert advice and international precedents. Based on these considerations, data were collected from several organizations, and a spatial database was systematically constructed. Finally, MBDSS (maritime boundary delimitation support system) was developed to support maritime boundary delimitation. This GIS-based system provides visual information about the considerations for the maritime boundary delimitation. Thus, it could help decision-makers to choose appropriate boundaries during the negotiation. Furthermore, this system is expected to be utilized as a scientific tool on the delimitation of maritime boundaries.

Coastal states are adopting maritime boundary delimitation as their primary maritime policy because maritime jurisdiction directly relates to vast economic interest. This becomes specially important and sensitive when complex maritime boundary issues are involved between neighboring coastal states. China has not actively carried out nor declared maritime boundary delimitation until recently with any country except Agreement between China and Viet Nam on the demarcation of the territorial water, the exclusive economic zones and the continental shelf of China and Vet Nam in the Gulf of Tonkin on 25 December 2000 (hereinafter, the Gulf of Tonkin Agreement). The principles that governs maritime boundary delimitation are to consider primarily an agreement between States concerned, however, if no agreement can be reached, all relevant circumstances are considered to achieve an equity between concerned States. Relevant circumstances are length of coastline, form of coastline, existence and position of island or islands, speciality of geology/topography, and factor of economy and deffnce. Factors which sinologists are considering in regard to continental shelf delimitation of the Yellow Sea are as follows; i) geographical factor, ii) geological factor, iii) topographical factor, iv) environment and ecological (factor, v) historic interest, and vi) social and economic interest. The 'Gulf of Tonkin Agreement' is completed by basically applying the principle of delimitation according to median line which seems that China has adopted the maritime boundary delimitation principle of 'half and half' which was the intention of chinese government. At the same time, China recognized Viet Nam's dominion and sovereign right over the partial exclusive economic zone and the continental shelf of Dao Bach Long Vi in Gulf of Tonkin. This case can be considered as an example of mutual concession or compromise in delimiting maritime boundary for states of concerned.

There are several Disputes relating to the delimitation of maritime boundary and the policy of maritime jurisdiction of the states around the Korea Peninsula. These disputes are connected with the place of 'Tokdo' dominated practically by Korea, 'Senkaku islands' dominated practically by Japan, and 'Kurile islands' that is under disputing between Russia and Japan. North Korea has also the problem. The delimitation of Maritime Boundary among these States would be concluded in very near future. Therefore, we need to understand the maritime jurisdiction policy of these states. South Korea also has to set the policy.

경계를 설정하기 위한 일반적인 방법은 등거리원칙이다. 등거리원칙은 각각의 기준선 또는 기준점의 경계에서 일정한 거리까지를 경계로 정하는 방법이다. 오랜 동안 해양의 공평한 경계를 정의하기 위한 노력이 진행되어, 모든 나라들이 적용할 수 있는 대양의 사용규제에 대한 단일협정인 유엔해양법협약이 채택되었다. 그 내용은 결국 당사국 간의 "공평"을 대원칙으로 한다는 것이다. 본 연구에서는 이러한 경계를 설정하는데 있어서의 한${\cdot}$일 양국의 실질적인 경계획선 방법에 대해 분석${\cdot}$비교하였다. 이를 위해 먼저 경계획선 과정에서의 기본이자 핵심이라 할 수 있는 양국의 측지계산 알고리즘을 분석하여 비교하였다. 양국의 실질적인 경계획선 알고리즘을 비교하기 위해 여러 가지 테스트를 수행하였다. 이에 향후 해양경계획정에 대비하여 효과적인 해양경계획선 알고리즘인 Three-Point 알고리즘을 제안한다. 또한 일본의 해양경계획선 알고리즘과의 비교를 통하여, 향후 경계분쟁에 대비한 기술적인 능력을 확보한다.

On 25 December 2000, China and Vietnam signed the Agreement on the Delimitation of the Territorial Seas, EEZs and Continental Shelves in the Tonkin Gulf. Three and a half years after signature, in June 2004, China and Vietnam both ratified a maritime boundary agreement for the Tonkin Gulf (Beibu Gulf) and the agreement entered into force. A potentially complicating factor in the negotiation process was likely to have been the status of the Sino-French Agreement of 1887. In the end, the agreement reached indicated that even if the status of the Sino-French Agreement of 1887 was part of the negotiations, both sides eventually agreed that it would not have an impact on the delimitation of maritime zones in the Gulf of Tonkin. Another crucial issue was the impact of the islands, in particular, the Vietnamese controlled Bach Long Vi Island and Con Co Island. Especially, Bach Long Vi Island was entitled to a half suite of maritime zones (3n.m. EEZ) and would impact the tracing of a line of equidistance in the Gulf of Tonkin. Minor as the point might be, Con Co Island also would have an impact for it would play a fixing terminal point for the boundary. Article 7 of the agreement is about minerals and hydrocarbons of cross-boundary deposit, and if any single geophysical structure of oil and gas or other mineral deposits should straddle the demarcation line, an agreement is to be reached on the development of the structure or deposit and on the most effective manner to equally share the profits resulting from the development.

최근 국내 여러 지방자치단체들은 해양개발이 활성화됨에 따라 관할해역 확보에 총력을 기울이고 있으며, 인접 지방자치단체간 분쟁의 증가로 인하여 관할해역 구분의 기준이 되는 해상경계의 중요성이 급격히 부각되고 있다. 특히, 해상경계 획정기준의 부재는 인접 지방자치단체들 간 분쟁을 발생시킬 수 있는 요소를 많이 내포함에 따라서 해상경계 획정기준 마련을 위한 노력이 절실히 필요하다고 할 수 있다. 본 논문에서는 과학적이고 합리적인 해상경계 획정기준을 마련하기 위하여 기 고시된 "해상경계 확인을 위한 수로측량업무규정"을 조사 분석하여 개선사항을 도출하였다. 그 결과 첫째, 해상경계 획정의 개념을 수립하였고 둘째, 해상경계 획정기준의 범위와 내용 및 절차를 구체적으로 설정하였으며, 마지막으로 지방자치단체들 간 해상경계 분쟁의 사전예방 및 사후 합법적 해결을 목적으로 해상경계조정위원회의 설치, 구성, 직무, 조정결과의 효력 등과 같은 해상경계 분쟁조정방법을 제시하였다.

Leaving the legacies of the Cold War and other difficulties behind them, South Korea and China are building up their successful strategic cooperative partnership, moving forward toward through the development of new economic exchanges and diplomatic cooperation between the two countries, and this process is expected to gain momentum during 2015. 2015 is the third year since President Park of South Korea and President Xi of China came into office, and also the first year they have begun to implement the many declarations and promises which they have made within the context of the strategic cooperative partnership. The two nations share a common cultural heritage, and their governments should take this opportunity to leverage their partnership to enhance their economies and to improve their people's quality of life, especially for the younger generation. At a summit held in July 2014, the two leaders agreed to launch a working-level group on maritime boundary delimitation. The first meeting took place on January 29, 2015, and addressed issues of Exclusive Economic Zones (EEZs) and continental shelves in the Yellow Sea, which has an area of about 380,000 ㎢. It is greatly to be hoped that the 2015 maritime boundary delimitation meeting between South Korea and China will not impair the future of bilateral relations, but rather will improve their prospects. South Korea and China must take the opportunity to secure a definitive delimitation of their maritime boundary; their strategic cooperative partnership is in good order and China is currently taking a somewhat more flexible stance on the ECS and the SCS, so an agreement on boundaries will serve as a useful model for regional maritime cooperation.

There are disputes for oil and gas development between China and Japan in the East China Sea. These involve the area where China is already carrying out activities of oil and gas development and where Japan is proclaiming its EEZ. China insists that the Chinese activities on oil and gas development area are being carried out within the Chinese jurisdictional waters even if the median line principle of Japanese proclamation is applied in delimitation. Indeed, the permit for Japanese development is causing disputes between China and Japan because its permit allows development in the waters adjacent to Chinese development area. h the event, the core of this dispute around the oil and gas field in the East China Sea relates to issues of maritime boundary delimitation and issues of resources acquisition with both states. Chinese policy on oil and gas development is to first consider development issues in accordance with a median line principle where waters toward to China from the median line should be developed by China and the area toward Japan from the median line within the Chinese continental shelf should be jointly developed. However, the Japanese position is that the East China Sea should be jointly developed, and Japan hopes to eventually convince China to accept its median line delimitation. With on-going development of such issues, Korea should establish a strategy of negotiation based on analyses of resource distributional conditions and other strategic factors in the Korean delimitation area. In particular, Korea should prepare and make the best use of joint development zone established in an agreement between the ROK and Japan concerning the development of the southern part of continental shelf adjacent to both states.

A reference to natural prolongation appeared for the first time in the North Sea Judgement. Although it was not suggested that the concept of natural prolongation would automatically allow for the fixing of a continental shelf boundary, that concept encouraged States to request international tribunals to determine continental shelf boundaries on the basis of the geological and geomorphological features of the seabed. In the Libya v. Malta Case, however, the rejection of geological and geomorphological factors was total. Especially, Natural prolongation was the then checkmated as a relevant fact in delimitation between coasts situated less than 400 nm. apart. There can be no doubt that, in several disputed cases, prominent geomorphological variations are simply ignored ; nevertheless, there are also a few agreements where geological and geomorphological characteristics come into play and, to a certain extent, affect maritime boundaries. Physical characteristics of sea-bed are generally given serious consideration in the boundary delimitation such as the final negotiated boundary of the Australia-Indonesia Continental Shelf boundary Agreement(Timor and Arafura seas) which follows the continental slope bordering the Timor Trench.

나라사이의 경계를 결정하기 위한 일반적인 방법은 등거리원칙이다. 등거리원칙은 각각의 기준선 또는 기준점의 경계에서 일정한 거리까지를 경계로 정하는 방법이다. 본 연구에서는 등거리 원칙을 기본으로 하는 알고리즘으로 폭넓게 사용되고 있는 Two-Point 알고리즘과 Three-Point 알고리즘을 정립한 후, 알고리즘을 적용한 결과와 오차를 확인할 수 있는 경계 획선 프로그램을 개발하였다. 이 프로그램은 인공지물이나 지형지물이 없어 경계를 결정하기 어려운 해양경계 획선시 특히 유용하게 사용될 수 있다. 그 중간점 계산결과 타원체상에서 등거리원칙에 기초한 알고리즘을 적용하면, 지도 투영에 의한 어떤 왜곡도 없이 적용할 수 있고 평면이나 구에서 적용한 것 보다 오차가 적었다. 경계 획선 프로그램 개발을 통하여 도면을 이용한 수작업에 의한 여러 오차를 제거 할 수 있고, 해양경계협상시 신속히 대처할 수 있다. 또한, 기준선의 기준점 위치에러는 계산된 중간선의 중간점으로 전파되는 것을 확인할 수 있었고 그 오차를 확인하여 적합한 기준면을 설정 할 수 있었다.
