Antique maps are a cultural heritage of recorded information with distinguished pictorial and scientific value. They have been utilized in a variety of academic fields, especially in historical geography, as the most fundamental data to look into the restoration of space or historic changes of area from the past. However, there is no sufficient study on the development of contents using antique maps in the exhibitions. Furthermore, there is almost no content research on the antique maps integrating the academic programs in museums or art galleries. In particular, it is very difficult to find research on the approaches to configure or utilize the exhibition contents related to the Sea of Korea using European antique maps. This study examined the construction of educational contents in order to use the European antique maps including the Sea of Korea as well as Korea itself in the exhibitions. The results of this study may visualize the results of academic research on the territory and territorial waters of Korea and extensively acknowledge them as scientific data all over the world. Furthermore, this study aimed to create the opportunity to increase interest in the Sea of Korea and recognize it again, to find the contents construction to use European antique maps as academic data for exhibition and education in museums or cultural facilities and to provide a basic model for history education using antique maps.

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.

The fishing vessels operation is a kind of maritime profit-making activities, which are complicatedly integrated by the basic and supplemental fishing activities with navigation. The Fishing Vessels Act of Korea defines the character of fishing vessels and gives a legal status to them, and this Act itself is linked with the allied public laws including the Ships Act of Korea. For this reason, the legal status of fishing vessels as Korean flagged ships by the public law is analogous to the general commercial vessels. And the specific character of ownership of the fishing vessels by the Korean Maritime-Commercial Act as a privated law is analogous to the general commercial vessels, nevertheless the Chapter 4(Carriage of goods) and the Chapter 5(General average) of this Act do not apply to the fishing vessels except the fish carriers. A fishing vessel possesses the legal status as a Korean flagged ship by having it registered and putting it on record under the provision of national law, however the principle of genuine link is an important factor for acquisition of nationality. Especially, the basic rules by the Law of the Sea those are attended with the distant-water fishing vessels operation at the overseas fishing ground are summarized as follows ; Firstly, the rights of navigation and fishing activities on the high seas are fundamentally recognized to all states, but the freedom is restricted according to the international legal order aiming at protection of reasonable interests of other states and conservation of the living resources and marine environment. Secondly, in the EEZ or EFZ the freedom of navigation is recognized, but fishing activities are exclusively ruled by the national law of the coastal state. Thirdly, foreign fishing activities are prohibited but the right of innocent passage is recognized in the territorial sea, while both activities are prohibited in the internal waters of the coastal state.

Korea's seas have the potentials of dispute against China or Japan due to the overlap of the territorial waters and EEZ. In case of marine accidents, the nature of the sea tends to eliminate much of the track, making it another hardship in evidence adoption in case of an international dispute along with the false entries of fishing vessels' journals. Marine Digital Forensics protects the functions of computers and IT appliance on vessels and extracts evidence of voyage and accidents to resolve international dispute. The digital evidence, if tampered with its integrity, may lead to the rejection to a critical claim or may even fail to make a case. As a solution, this thesis suggests Marine Digital Forensics as a way to extract evidence and prove a claim. This may be utilized as means of scientific investigation on sea as overseas exchange increases and the vessels digitalize, leading to a solution in international disputes that may occur in the future.

In this paper, offshore wind resources within the Japan's EEZ (Exclusive Economic Zone) are assessed using wind speed data from the microwave scatterometer SeaWinds onboard QuikSCAT. At first, from the 10m-height wind speed from QuikSCAT, 60 m-height wind speed is estimated by using an empirical equation for height correction. Based on the 60 m-height wind speeds, annual energy Production is calculated under an assumption of installing 2 MW wind turbines every $0.64km^2$. The annual energy production is then accumulated for the entire Japan's territorial waters and EEZ ($4.47{\times}10^6km^2$). As a result, it is shown that the total energy Production is estimated to be $4.86{\times}10^4$ TWh/yr. This offshore wind energy Potential within the EEZ is approximately 50 times higher than the actual annual electricity production in Japan.

Although the uninhabitable islands are part of national property, those are not systematically managed and controlled in Korea. In this study, the positioning standards for uninhabitable islands are suggested with proper surveying methods. To establish the standards, the current status on managing the uninhabitable islands in foreign countries are investigated and analyzed. It was found that it is necessary to establish the ocean geodetic network based on a sound and systematic plan. In Korea, the ocean geodetic network can be established by combining the National control point and territorial sea control points. We suggested that one or two third or fourth control points are required to be established in total of 2,679 islands with connection to the 47and 249 first and second-order control points. It is expected that this network will provide ground control points for aerial and satellite images for large scale ocean mapping. In addition, close cooperation among the related departments such as Ministry of Construction & Transportation, National Geographic Information Institute, Ministry of Government Administration and Home Affairs, Ministry of Maritime Affairs and Fisheries, and Ministry of Environment is necessary for successful management on uninhabitable islands.

Extraction of the coastal boundary is important because the boundary serves as a reference in the demarcation of maritime zones such as territorial sea, contiguous zone, and exclusive economic zone. Accurate nautical charts also depend on well established, accurate, consistent, and current coastline delineation. However, to identify the precise location of the coastal boundary is a difficult task due to tidal and wave motions. This paper presents an efficient way to extract coastlines by applying digital image processing techniques to Synthetic Aperture Radar (SAR) imagery. Over the past few years, satellite-based SAR and high resolution airborne SAR images have become available, and SAR has been evaluated as a new mapping technology. Using remotely sensed data gives benefits in several aspects, especially SAR is largely unaffected by weather constraints, is operational at night time over a large area, and provides high contrast between water and land areas. Various image processing techniques including region growing, texture-based image segmentation, local entropy method, and refinement with image pyramid were implemented to extract the coastline in this study. Finally, the results were compared with existing coastline data derived from aerial photographs.

The situation in Northeast Asia is rapidly changed because of the territorial dispute between neighboring countries near the East China Sea, North Korean nuclear bomb tests, long-range ballistic missile launching tests frequently and deployment of Chinese Liaoning class aircraft carrier. Especially, unstable political situation of North Korea and Chinese A2/AD strategy by strengthening naval forces are the cause of replanning Asia-Pacific security strategy of Unites States. In this paper, it is surveyed and analyzed that changed Asia-Pacific security strategy of U.S. and rearrangement plan of U.S. Naval forces. And changed environmental situation influence on our security is analyzed.

Even though marine casualities are recently occuring so frequently in territorial sea or beyond, that causing danger to navigation, yet no international regimes are officially made to cope with such an impediment efficiently. However, Internatinal Maritime Organization (IMO) commenced to work for adopting an appropriate internaitnal convention on wreck removal under co-operation with Comite' Maritime International (CMI). The legal committee of the CMI has already provided full comments on draft convention of the wreck romoval and duly submitted to IMO as a reference which was made on the basis of their principles of unification and harmonization. Accordingly, this paper re-arranged in order aiming to understand easily for legal aspects of the draft convention comprehensively in accordance with full contents provided by the CMI. To avoid any improper applicationor undue interpretation after fixing of the convention , every coastal state which has keen interests should trace its background of legal information from initial stage. Accordingly, the paper will contribute not only to realize how to draw a whole legal picture including specific articles on the convention fixable in the future but also to the national legislation with understanding full legal history of the convention.

Dokdo has historical and political meaning in relation to the territorial problems with Japan. The area can be the main factor to explain the formation and development process of East-Sea as exposure volcanic island at East-Sea with Ulreong-island. Accordingly, it also has an important meaning of physical geography aspects In this research, it is perceived the geomorphological development process of slope due to the salt weathering which is considered as the most important factor to understand whole geomorphology of Dokdo. And researched how a geomorphology of this sort affects to animal and plants. The peculiar geomorphology is tafoni which is a weathering geomorphology and one of the remarkable geomorphology in preservation of Dokdo. Tafoni at west part of Dongdo is distributed intensively near shoreline which is composed tuff. The shape of tafoni is mainly massive, circle and oval in Massive tuff breccia layer also is formed toward horizontality bedding direction in Bedded lapilli tuff. Tafoni in Dokdo is constituted after middle of Holocene. This fact can be proved by ranging at surface of sea-cliff which is formed wave erosion after middle of Holocene sea-level reaching to present level. Tafoni is also the most contribute factor of geomorphology dissection of Dokdo as it is eroded the bed rock with salt weathering. In bottom part of tafoni it has an important function for habitat of birds. Herbaceous plants are on it. To procrastinate of bed rock dissection by growth of Tafoni, conservation of vegetation and soil are most important factor.
