We have proposed Fuzzy-CBR to find a solution from past knowledge retrieved from the database and adapted to a new situation. However, ontology is needed in identifying concepts, relations and instances that are involved in a situation in order to improve and facilitate the efficient retrieval of similar cases from the CBR database. This paper proposes the way to apply ontology fur identifying the concepts involved in a new case, used as inputs, for a ship collision avoidance support system and in solving for similarity through document articulation and abstraction levels. These ontologies will be used to build a conceptual model of a maneuvering situation.

In order to improve the employment rate of graduates in maritime and fisheries high schools, we investigated the employment situations of the those graduates for the last 8 years. The results were as follows, The ratio of graduates in maritime and fisheries high schools to total graduates of on-board departments are 69.1% and 30.9% respectively. The on-board employment rate of maritime high schools and fisheries high schools graduates are 63.2% and 26.7% respectively. Nearly all of the maritime high schools students were employed to merchant ship and fisheries high schools students were employed to merchant ship 77.2% and only 22.8% of them got a job on fisheries ship. The ratio of getting a job in maritime high schools to ocean-going ship was 76.7%, that was the highest ratio and the ratio of fisheries high schools got a job to ocean-going ship was 55.1%. The on-board career of maritime high schools graduates was 1~5 years, which took 86.4% of all careers and that of fisheries high schools was less than 1 year, which took 60.0% of all careers. We should make the various efforts to improve the employment rate of getting job to fisheries ship in the fisheries high school graduates.

East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

The European expansion in the later middle age, as Adam Smith stated, influenced greatly on development of the world history. In the various events of the European expansion the discovery of the New World by Christopher Columbus is very important because the effect of the discovery of the New World have still continued to the present. I have interested to find out the reason why the western civilization has seized on the hegemony of the world over other civilizations. As many scholars pointed out, the most distinguished difference between the western civilization and other civilizations is that the western civilization was maritime-oriented, while other civilization were continental-oriented. So I set up the maritime histoy on the theme of my study in order to ruminate upon meaning of the se-power that is one of the motivating forces to drive histoy. Maritime history is not simply about that is maritime affairs, but a branch of history that inquires into inter-relations between maritime affairs and inland affairs. Maritime history constitutes of history of naval war, history of shipping and history of marine development. As above reasons, I have interested the European expansion in the later middle age that maritime activity was the most vigorous in the history. This is a case study to compose maritime history.

In order to improve the employment rate of graduates in maritime and fisheries universities, we investigated the employment situations of the those graduates for the last 7 years. The results were as follows, The ratio of graduates in maritime and fisheries universities to total graduates of on-board departments are 69.1% and 30.9% respectively. The on-board employment rate of maritime universities and fisheries universities graduates are 63.2% and 26.7% respectively. Nearly all of the maritime universities students were employed to merchant ship and fisheries universities students were employed to merchant ship 77.2% and only 22.8% of them got a job on fisheries ship. The ratio of getting a job in maritime universities to ocean-going ship was 76.7%, that was the highest ratio and the ratio of fisheries universities got a job to ocean-going ship was 55.1%. The on-board career of maritime universities graduates was 1~5 years, which took 86.4% of all careers and that of fisheries universities was less than 1 year, which took 60.0% of all careers. We should make the various efforts to improve the employment rate of getting job to fisheries ship in the fisheries university gradustes.

This paper is designed to make a national strategic concept for the ROK's maritime security and to explore cooperation directions for the ROK Navy and Coast Guard in order to implement the newly-made maritime security strategic concept. As strategy is composed of three main categories(goals, ways, means), the goal of the ROK's maritime security strategy is 'Safe and Affluent Sea' and the way to realize the goal is the principle of cooperative leverage, and the means as tasks to implement the strategic concept are maritime safety, maritime security, and maritime stewardship. The concept of national fleet as used in the US is applied to promoting the cooperation between the ROK Navy and Coast Guard. Thus, under the newly-established maritime security strategic concept along with the national fleet model, followings are suggested as policy proposals for facilitating mutual cooperation between the ROK Navy and Coast Guard in dealing with not only traditional threats but also non-traditional treats at sea and from the sea as well. First, the ROK Navy and Coast Guard has been making efforts to enhance interoperability between the two sea services. However, the mutual cooperations have been focused mainly on areas on operational level rather than policy level. Therefore, the two sea services are recommended to enlarge exchanges and cooperation in policy areas. Second, there are still demands for further cooperation areas between the two sea services in command and communications. The interoperability in C2 between the two needs to be upgraded even to the areas of anti-terrorist activities ar sea, ASUW, ASW, maritime interdiction, etc. Third, mutual comparability between the two needs to be reflected in the maritime forces development to ensure the comparability in UNREP and other logistics areas. Fourth, the standardization of logistical materials and equipments is needed as a way of sustaining operational capability and logistical capacity for the ROK Navy and Coast Guard as well. Fifth, the ROK Navy and Coast Guard are recommended to participate more actively in international maritime cooperation activities such as PASSEX. Sixth, Complementary laws and regulations need further to be revised and to be newly made for collectively managing swiftly maritime accidents and natural disasters at sea.
