Vessel Traffic Service (VTS) is being used at ports and in coastal areas of the world for preventing accidents and improving efficiency of the vessels at sea on the basis of "IMO RESOLUTION A.857 (20) on Guidelines for Vessel Traffic Services". Currently, VTS plays an important role in the prevention of maritime accidents, as ships are required to participate in the system. Ships are diversified and traffic situations in ports and coastal areas have become more complicated than before. The role of VTS operator (VTSO) has been enlarged because of these reasons, and VTSO is required to be clearly aware of maritime situations and take decisions in emergency situations. In this paper, we propose a prediction table to improve the work of VTSO through the Cognitive Work Analysis (CWA), which analyzes the VTS work very systematically. The required data were collected through interviews and observations of 14 VTSOs. The prediction tool supports decision-making in terms of a proactive measure for the prevention of maritime accidents.

This paper describes recently developed PC based Aids to Navigation Training Simulator (AtoN-TS) using Virtual Reality Modeling language (VRML). The purpose of AtoN-TS is to train entry-level cadets to reduce the amount of sea-time training. The practical application procedure of VR technology to implement AtoN-TS is represented. The construction method of virtual waterway world, according to the guidelines of International Association of Lighthouse Authorities (IALA) is proposed. Design concepts and simulation experiments are also discussed. Results from trial tests and evaluations by subject assessment, provide practical insight on the importance of AtoN-TS.

현재 선박에서 항해사에게 항로정보를 제공하는 장비는 ECDIS와 GPS 플로터가 많이 사용되고 있으나 자동항로생성 및 항로설명기능이 없어 숙련된. 항해사만 사용할 구 있는 문제가 있으며, 특히 종이해도의 대체 시스템인 ECDIS에 사용되는 ENC를 이용한 자동항로생성 및 항로 설명에 관한 연구는 없는 실정이다. ENC는 IHO에서 정의한 S-52, S-57 표준포멧을 기반으로 제작된다. 본 논문에서는 ENC의 해도데이터와 GPS의 위치데이터, Anemometer의 풍향$\cdot$풍속데이터, 조류데이터를 이용하여 현 위치에서 목적지까지의 최적항로를 설계하여 안내해주는 통합형 항해가이딩시스템(INGS)을 구축하여 그 유효성을 확인하였다.

In these days, several bridges have been built or under construction over navigational channel in Korea In these cases there must be careful consideration for the marine safety of vessels to be passed by below the bridge. This paper aims to analyze the factors influencing maritime traffic safety and to figure out ample width of main span of these kinds of bridges through the reference study and FMSS.

The last goof if the study is to develop a law cost and a readily available Virtual Reality (VR) based Ship Handling Simulator using Personal Computer. This paper mainly describes procedures and methods to control the dynamic motions if the 3D ship object with maneuvering coefficients in a virtual navigation world The creation if virtual navigation world, the mathematical background q a ship control, and the construction of the system are also discussed.

This paper considered the concept and characteristic OSV operation business for support the offshore plant and suggested amendment Maritime Transportation Laws, legislative proposals to solve the legal absence and to develop offshore service industry. Because Maritime Transportation Laws specialized for the carriage of passenger and goods by sea is not perfectly covered with Offshore support business in Korea. So it is necessary to make an explicit amendments for the article of Maritime Transportation Laws that founds absence of the law with the definition of terms to correspond related existed regulation reflected on the characteristic offshore support business by using OSV to develop offshore plant industry including support, service, supply, transportation etc. I expect that this paper will be a basic study to make a government policy, law, regulation to activate Offshore Service Industry in the future.

This study aims to present about current status of logistics in Mongolia. As a landlocked country have limited the role of a maritime transportation is a very poor country. However, Mongolia is a rich country in mineral resources in the world and became a center of increasing international trade. Therefore, Mongolia wants to develop logistics as other developed countries using a strategic location. Mongolia uses international port for transit China and Russia by railway. First, this paper focuses on discussing the current situation of logistics. Second it points out some issues currently facing by the governmental policy to promote. Finally, this paper presents some recommendations for developing logistics in Mongolia. The geographical remoteness of Mongolia which results in high cost of transport causes problems for trade relations with the rest of the world to grow.

Accidents between ships occur frequently at the traffic congestion area. Once a maritime accidents occur, it is likely to end up with critical damaged accidents. This paper develop a simulator for assessing quantitative risk based on statical maritime traffic data and realtime traffic distribution. Ship's passage risk assessment simulator consist of import of division of passage data, traffic distribution analysis and passage risk assessment analysis. Maritime traffic data of WANDO waterway apply to simulator for calculation of quantitative risk rate of waterway.
