Marine Casualties cause the loss of hmm lives, properties and marine pollution. The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. The coastal VTS and navigational aids are considered as one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build. Thus prior to establishing these coastal VTS and navigational aids, it should be evaluated the navigational safety level in the coastal waterways in concern. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy measure and integral to represent the fuzziness in the evaluation process. Therefore this paper aims to develop the method for this evaluation using the fuzzy measure and integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids. The results are found as order as Mokpo, Yosu, Pohang, Busan, Inchon, Geoje, Gunsan, Donghae coastal area.

The current AIS network and. system are run on a full scale with 22 ground stations and. 11 operational systems, completing a nation-wide, integrated network However, currently it needs to manage sea traffic by linking AIS to VIS which 1vs a limited service area due to restricted radar detection zones in harbors or coastal areas. Accordingly this study analyzes the current status of the AIS system and. proposes technological and. operational improvement plan of the current AIS system through investigating the actual conditions of the AIS system and. its operations.

IOn 7th of Dec. 2007, large oil spill took place the seas off the Taean coast caused by the collision between VLCC Hebei Spirit and crane floating barge Samsung-1 and a lot of problems were revealed during response to the accident. The author, accordingly, examined to analyze the cause of this accident on the aspect of spill prevention and presented some preventive measures, such as strictness to the current standard for tug operation, expansion of VTS service area and transfer of the VTS responsibility to Korea Coast Guard, designation of appropriate anchorage per ship's type, cargo and visiting purpose, and special management for dangerous goods carriers.

In Early vessels did not provide an exact equation for preventig the capsizing vessels. On land, many vehicle rollover prevention technologies using the steady-state Conrning Equations were developed, which showed better performance than the exiting method at sea. For better performance, It is proposed to improve safety mangement when turning vessel using the Ackerman geometic model-based Cornering Equations in this paper.

The prevention of marine accidents has been a major topic in marine society and various polides and countermeasures rave been developed, applied to the industries. 1he coastal VIS and navigational aids are considered as one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build Thus prior to establishing these coastal VIS and navigational aids, it should be evaluated the navigational safety level in the coastal waterways from the Environmental Stress. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy measure and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VIS and navigational aids.

현재 VTS센터에서 사용되고 있는 항만자동안내방송시스템은 VHF음성통신을 기반으로 하고 있어 그 방송범위에 제약이 있다. 최근 AIS의 보급이 확대됨에 따라 AIS신호가 연안해역에서 약 100마일까지 송수신이 되고 있다. 이에 본 연구에서는 기존에 전국의 VTS에 설치되어 있는 VHF음성통신 항만자동안내방송시스템에 AIS TEXT MESSAGE기능을 통합 운영하여 연안해역까지 해상안전을 위한 자동안내방송을 확대하고자 함이 그 목적이다.

해상 교통량 증가에 따른 연안해역 해상교통밀집도가 증가되고 있다. 그러므로 해상교통안전관리를 위해 실 해역의 해상교통패턴을 파악하여 해상교통지수를 평가하는 것이 중요하다. 분석대상해역의 실제 선박위치, 속력, 침로를 고려한 CPA-TCPA분석은 통계적인 선박데이터에 의한 분석보다 해당해역의 실제적인 VTS영향 등 교통환경을 반영한다. 본 연구에서는 횡간수도와 완도진입수로의 항로가동률을 분석하고, 해당 해역에서 교차되는 선박들의 CPA, TCPA 등을 분석하여 해상교통안전지수를 평가하고자 한다. 또한 산출된 해상교통안전지수를 해당 해역의 통계적인 해상교통안전지수와 비교 및 분석하고자 한다.

The prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. In order to improve the navigational safety level in the coastal waterways, the navigational safety level must be evaluated from the mariner's perception of safety. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy measure and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids. The results are found in the order named Mokpo, Yosu, Pohang, Inchon, Busan, Geoje, Gunsan, Donghae coastal area.
