The most important bases of maritime laws in China are laws enacted by Constitution, a legislative institution of National People's Congress and Legislation of NPC Standing Committee. However, in reality, the institution, which become the basis of Chinese marine policy and leads overall maritime affairs, is a State Council of the Chinese central government and many objects of our researches on Chinese marine policy and laws are composed centering on this administration law. Therefore, in understanding Chinese maritime laws, it becomes an important prerequisite to understand relevant laws (statutes), administration law, statutes of local province, mutual authority relationships of these legislative institutions, and interpretation authority regarding laws (statutes). In May 2003, Chinese State Council ratified and declared ${\ll}$Guideline of the national maritime economic development plan${\gg}$ and this is the first macroinstructive document enacted by the Chinese government for promoting maritime economy in integration development. This plan guideline shows very well a new policy and deployment direction of maritime policy in China. China is already striving to lead its maintenance stage of domestic legislation into a new stage under the UN maritime laws agreement system and this is an expression of intention to take national policy regarding the ocean as a new milestone for the national economy through concurrent developments in various fields such as national territory, economy, science technology, national defense, and maritime biology. In this point, Chinese maritime policy and maritime legislation provide lots of indexes of lessons in many parts. In particular, regarding Korea, which has to solve many issues with China in Yellow Sea, East China Sea, and Balhae, we have to realize that we can maximize national interest only with a systematic approach to research on changes of domestic policies and maritime legislation within China. In addition, in understanding Chinese maritime related laws, we have to realize it is an important task to not only understand legislative subjects for mutual creation of order within the entire frame of law orders of China but also to predict and react to direction of policy of Chinese domestic legislation through dynamics of these subjects.

In those day, Incheon and Busan local government are arguing about establishment of a maritime court. This study aims to develop a model that evaluates the priority orders for the establishment of maritime courts using maritime casualties counts based on the integrated ELECTRE-CRITIC-ISM technique, as well as to verify its usefulness in the establishment of maritime courts in Korea. For this purpose, a total of 22 ports, excluding nine ports where maritime accident data were integrated and managed among the 31 international trade ports, were matched with the jurisdiction of six alternative high courts. Second, the CRITIC method was used to calculate the weights of the number of maritime casualties during a 5-year period that were evaluation factors and combine with the ELECTRE method. Finally, the ELECTRE&ISM method was used to analyze the concordance and discordance between high courts and evaluate the priority orders considering the fluctuations of maritime casualties counts. As the final evaluation result considering the mean values in fluctuations of maritime casualties counts, the Busan High Court ranked first, the Gwangju high court second, the Seoul high court third, the Daejeon and the Daegu high court forth (equal), and the Suwon high court sith. Therefore, it is necessary to preferentially establish a maritime court in the jurisdiction of the Busan High Court.

Even if the HF band SSB maritime data communications service company has operating a target Of the member ship, because of unprepared. the radio link protocol that has been question accordance with increase of calling redundancy at traffic overload. Although free signal has operating for traffic of the next ship, but cannot avoid the collision in mutual calling ships. In feature of HF band SSB channel that radio link must be established by automatical, stability and adaptive at over load. In this factor, this paper is studied the new radio protocol by 3 step sequency driving of free access, group free access and polling access.

The purpose of this paper is to analyze maritime piracy and its economic implications with particular attention to attacks registered in the Gulf of Aden, The paper also aims to investigate how the International community, along with Sovereign States, should allocate resources in order to make the seas a safer place and describe how closely inter-related maritime piracy, preventive and punitive measures put in place by Governments are. Elements of economics and ergonomics are taken into account in order to properly investigate the major legal issues relating to maritime security. The paper proposes a cost-benefit analysis in order to investigate in theory what is the rationale behind engaging in criminal behavior and recommend some solutions to the issue to be undertaken by the International community. It is concluded that in order to cost effectively fight piracy, a mix of more coordinated National and International laws, standardized and increased punishment levels among jurisdictions and extended patrol controls are needed.

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.

The vessel encounter data collected from the vessel trajectories in the maritime traffic situation is possible to analyze vessel collision and near-collision risk using statistical method. In this study, analyzing variables extracted from the vessel encounter data using factor analysis, we determine main factors effecting vessel collision risk from vessel encounter data. In order to calculate each factor, it used principal component analysis for factor analysis after normalization and standardization of vessel encounter variables. As a result of the factor analysis, main effect factors are summarized into the vessel approach factor and collision avoidance variance factor.
