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.

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.

The official talks on the amendment of the Korean - Japanese Fisheries Agreement which was concluded in 1965 are under way since 1996. The convention area of the existing fisheries agreement is the high sea, but it should be changed to the exclusive economic zone(EEZ) for the newly amended fisheries agreement. Accordingly, the fundamental policies to be embodied within the amended fisheries agreement are summarized as follows : 1. One of the basic doctrine of the new agreement should be the formulation of a device of international cooperation for the fishery development as well as the conservation and management of the fishery resources. 2. The preparation of the future-oriented international relationship which reflects the specific character of the fishery relationship between both countries. 3. The existing fishery results of both parties should be protected on the ground of the reciprocity principle. 4. Both parties should reach an agreement upon the joint conservation and management measures for the transboundary fishery resources. 5. In consideration of the difficulty of EEZ delimitation between both countries, a provisional fisheries agreement can be an alternative measure.

We describe and illustrate five species of shrimp of the genus Solenocera, collected from the Korean exclusive economic zone (EEZ) between 2001 and 2003 and a commercial seafood market in Busan, South Korea, in 2005. Four of these species, S. alticarinata Kubo 1949, S. comata Stebbing 1915, S. koelbeli De Man 1911, and S. pectinulata Kubo 1949, are new records for the Koreas. The fifth, S. melantho De Man 1907, is a ubiquitous and commercially important species in the region. This report extends the known range of S. pectinulata to Jeju Island in the East China Sea. A key to these species is presented.

Ten species of Galatheoidea (squat lobsters), belonging to two families, were collected in the Korean exclusive economic zone: Galathea balssi Miyake and Baba, 1964, Galathea orientalis Stimpson, 1858, Galathea pubescens Stimpson, 1858, and Galathea rubromaculata Miyake and Baba, 1967 belonging to Galatheidae; Bathymunida brevirostris Yokoya, 1933, Cervimunida princeps Benedict, 1902, Munida caesura Macpherson and Baba, 1993, Munida japonica Stimpson, 1858, Munida pherusa Macpherson and Baba, 1993, and Paramunida scabra (Henderson, 1885) belonging to Munididae. The present study comprises the morphological description of these ten species, including drawings and color photographs, a brief review of their regional records, and a key for their identification. Although all species are common in Japanese waters, G. balssi, G. rubromaculata, B. brevirostris, C. princeps, M. caesura, and M. pherusa are new to Korean marine fauna.

The problem of imbalance between supply and demand of fine aggregates in the southeastern region due to the decrease in collection of EEZ(Exclusive Economic Zone) sea sand has been raised. In this paper, the possibility of securing alternative aggregate as a means to solve the problem of fine aggregate shortage in the southeast region was analyzed. As a result of the analysis, the alternative aggregate is easy to manufacture and its quality can be secured. And, it is suitable to use as an aggregate with less environmental burden. In addition, institutional improvement measures are needed for effective utilization and recycling of alternative aggregates.

Information on maritime boundaries is essential to manage ocean and fisheries effectively in the era of the UN Convention on the Law of the Sea. With various information regarding to maritime boundaries analysed and reviewed, maritime boundaries are mainly divided into two categories such as international and domestic boundaries and also sub-divided into two aspects such as administrative and other boundaries. After clarification of boundary information, the geographical natures of boundaries, for instance datum, projection, line types, are reviewed. The Geographic Information Systems (GIS) is used for the establishment, management and utilization of boundary information due to its strong function in database, analysis, visualization, etc.

Only four species of leuconids have been recorded in Korea, all belonging to the genera Eudorella Norman, 1867 and Nippoleucon Watling, 1991. In this study, Pseudoleucon japonicus Gamô, 1964 belonging to family Leuconidae Sars, 1878 is newly recorded for Korean cumacean fauna. Also, for the first time, the male of the species is fully described and illustrated. The specimens were collected from the exclusive economic zone (EEZ) in the western sea (Yellow Sea) of Korea, with a rectangular dredge during 2007-2008. This species is characterized by the following features: the carapace has strong serrations on the antero-lateral margin and a pair of short oblique ridges on the side surface; the ridges begin near the end of frontal lobe and merge with the dorsal median carina; the appendages, such as antenna 1, pereopod 2 and uropod have a lot of simple setae decorated with a bundle of hairs at the end. The present study represents the first record on the genus Pseudoleucon Zimmer, 1903 from Korea.

The purpose of this paper is to search for reasonable and fair principles applicable to the delimitation of the Exclusive Economic Zone(which is called the EEZ, hereinafter) around the Korean Peninsula th-rought the comprehensive study of maritime boundary, which is one of the most important issues in the law of the Sea. So far, the sea has been exploited for activities such as fishery, transport and military stratedy, and en-vironmental policy and so on. From this time on, however, it becomes important to us as the major trea-sure-house of various resources which will be developed and used for diversified purposes. For these rea-sons, nowadays, more and more countries of the world are competing to secure waters as much as possible within their jurisdiction. And the regime of the EEZ was created as a result of this international trend. At last, it has been institutionalized as the 200-mile EEZ of a legal notion in the Convention on the Law of the Sea, which was adopted at the Third United Nations Conference on the Law of the Sea, in Jamaica on December 10, 1982. In adapting to this EEZ institution, Korea is faced with several complicated problems as it is bounded on three sides by the sea and all of its neighboring countries such as the PRC, the DPRK, Japan, Russia etc are less than 400 miles away between opposite countries. Therefore, when trying to delimit the boun-dary for the EEZ, it appears necessary to analyze applicable principles and rules of international law for delimitation mainly through the Convention on the Law of the Sea, and studies the trends of actual State practices and recent international precedents. It is hoped that such knowledge will enable Korea to secure sufficient resources and other sovereign rights without conflicting with the neighboring countries concer-ned. For the achievement of the above mentioned object. I analyzed the necessities of the establishment of the EEZ in Korea, the difficulties and practices of Korea's neighbors, and the changes and forthcoming trends in Korea's relations with its neighbors concerned on the basis of the general explanation of the EEZ regime. In conclusion, it is my opinion that for the establishment of the EEZ delimitation which neighbors around the Korean Peninsula should be applied reasonable and equitable principles considering the rele-vant circumstances which characterize the area definitely as well as the UN Convention on the Law of the Sea, 1982.
