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.

The marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway these days. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. In this paper, the probability analysis of marine casualties in Korean coast. To achieve this aim, clears up the cause of accident and examines closely the mutual relations among marine casualties, weather condition, and marine traffic volume. These casualties are classified into several patterns or the point of view of ship's size, ship's type and ship's age and its characteristics of each pattern are described In detail.

The purpose of this study is to present safety management improvement measures for domestic coastal accidents. The national coast was classified into five regions to investigate the status of safety accidents. Based on literature review and interviews with practitioners, problems of coastal accident safety management were derived and the improvement were suggested. The results of this study are as follows: 1) Of the 3,116 coastal accidents in Korea, rock on the shore and central sea accidents accounted for 37.58% and 30.67%, respectively. 2) In order to improve domestic coastal safety management, five measures such as the establishment of private cooperation governance were suggested.

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.

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 a, 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 risk 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 logic 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.

최근들어 항만건설 및 선박블록 운송의 증가로 대형 부선을 예인하는 예부선과 침몰 선박 인양 및 해상교량공사 등을 위한 해상크레인 운송선단의 통항이 매년 증가 추세에 있다. 우리나라에서 이들 선박의 주 항로는 남해와 서해 연안으로, 이 지역은 도서가 산재해 있고 협수로가 많은 지형적 특성과 연안으로 근접하여 항해 시 강한 조류의 영향을 받으며, 또한 어망과 조업중인 어선들과 많이 조우하게 된다. 특히, 돌발적인 해양 기상적 특징을 포함하고 있다. 이러한 영향에 따라서 이 해역을 통항하는 예부선 및 해상크레인 선단의 조종성능이 크게 저하되어 해양사고의 위험성이 고조되고 있다. 이에 따라서, 이 연구에서는 해상크레인의 연안해역 예항시 안전하게 항해할 수 있는 적절한 조종 방법을 고찰하여 안전운항에 기여하고자 한다.

Recently, the risk of safety accidents in the coastal zone has been increased due to revitalization of marine leisure and tourism. Because of a lack of regulations about technical and maintenance aspect for safety facilities, the effective measures to prevent safety accidents in the coastal zone have not taken with increasing rate of the accidents. The nature of land/sea and behavioral characteristics of a fisherman/port laborer/tourist/people at leisure should be taken into account properly when safety facilities to prevent safety accidents in the coastal zone are installed, since the characteristics of land/sea and many activities such as fishery, harbor works, tour, leisure are mixed in the geographic and environmental condition of the coastal zone. This study analyzes the current problems on the safety facility in the domestic coastal zone through the domestic and foreign(Hongkong, Macau) field survey. Also the direction of the improvement about the safety facility are proposed.

우리나라 연안 해역은 빈번한 선박조우로 인하여 해양사고 발생 잠재 위험이 높은 해역으로 분류되고 있으나 해상교통의 정량적인 평가의 미흡으로 맞춤형 안전대책이 제대로 수립되고 있지 않는 것이 현실이다. 본 연구에서는 해상교통 안전성 평가모델 중 하나인 IWRAP(IALA Waterway Risk Assessment Program)에 대한 기본적인 소개와 함께, 울산항을 대상으로 한 평가 사례 소개, 기존 유사한 연구와의 비교를 하고자 한다.

우리나라를 비롯한 세계적인 물동량 증가로 국내 항만에 입출항하는 선박 척수의 지속적 증가, 연안 및 원양해역에서 선박간 위험한 조우상황의 빈번한 발생 등과 함께 국내 연안 해역에서의 해양사고 발생 건수가 꾸준하게 증가하고 있다. 최근 5년간의 해양사고의 주 원인으로 선원의 인적과실에 의한 해양사고가 약 90%에 달하며, 사고원인은 운항과실(항행법규위반, 조선부적절)이 대부분을 차지하고 있는 실정이다. 본 연구에서는 인적과실로 인한 사고예방을 위해 진행되고 있는 BRM과 SHS교육의 문제점을 분석하고 효과적인 교육 훈련 지침을 제시하였다. 또한 안전운항 평가 모듈 마련에 이용하기 위해 항해사들의 판단에 맡겨져 있는 초동조치 개시거리와 안전 이격거리 설정을 설문자료를 바탕으로 정량화하였다.
