디지털 기술의 발전에 따라 해상환경은 빠르게 변화할 것으로 예상된다. 자율운항선박의 경우 국내ㆍ외 많은 국가에서 기술개 발 중이며, 국제사회는 이를 운용하기 위한 논의도 시작되었다. 선박의 변화는 해상교통 환경의 변화를 야기하며, 육상지원시설에 대한 변화도 촉구한다. 본 연구는 항행지원시설의 사이버 보안 체계 개선을 위해 해상교통관제 인원의 사이버 보안 관리 인식을 분석하고자 한다. 이를 위해 해상교통관제 중심으로 사이버 보안 관리 현황을 살펴보고, 해상통관제 인원을 대상으로 설문조사를 실시하였다. 설문조 사 분석은 IPA 방법론을 활용했으며, 분석결과 보안담당 경험이 있는 인원과 경험 없는 인원의 사이버 보안에 대한 인식차이가 뚜렷하게 나타났다. 더불어 사이버 공격 탐지 및 차단 관련 기술적인 조치가 가장 우선적으로 시행되어야할 사항으로 나타났다. 본 연구 결과는 항 행지원시설에 대한 사이버 보안 관리 체계 개선을 위한 기초자료로 사용될 수 있다.

Recently IMO and IALA have developed the strategy of e-Navigation and the concepts of VTM to enhance the safety, efficiency and security of vessel traffic and protection of the marine environment. And current technical and functional trends require vessel traffic management systems to be improved so as to control vessel traffic not only in waters of harbour area, but also within EEZ waters. Under the consideration of these circumstances, a three-layered vessel traffic management system was proposed in this paper. The proposed system consists of three sub-systems, called Local VTS, Regional VTS and National VTS, and those sub-systems are designed respectively to be suitable for managing vessel traffic within their own jurisdiction waters.

The increase in seaborne cargoes has made our coastal traffic congested, and future coastal traffic is also expected to increase considerably as result of our economic development and high dependence on foreign trade. This increased traffic may be a cause of serious sea pollution as well as greater number of sea accidents. In view of this problem the introduction of VTMS along on our coast is required, following careful study of a large number of foreign systems. This paper analyzes the actual condition of 132 VTMSs in the world from the view point of management method authority of VTMS, coverage and characteristics of system. And this results provide helpful information for the development of VTMS in the future and for the implementation of VTMS in our coastal waterway.

The amount of cargoes and fishery production have increased continuously during the last decade due to the great growth of the Korean economy. These increasements have made our coastal traffic congested, and the future coastal traffic is also expected to increase considerably. The increased traffic can be a cause of large sea pollution as well a s greater sea casualties us as properties and human lives, which could result in a big national loss. In order to prevent the sea casualties and promote the safety of coastal traffic, the Vessel Traffic Management System (VTMS) along the Korean coastal waterway is inevitably introduced. But, the precise evaluation is necessary required prior to the implementation of VTMS because this system necessitates a huge amount of budgets. This paper aims to propose the model of evaluation process, but the evaluation as to the urgency of establishment is not only very complicated and fuzzy but also affected by the subjectivity of human. Therefore, fuzzy integral is adopted as the mathematical model of evaluation in which decision-maker can intervence by making decision considering the calculated membership-function. Four aspects, namely, the frequency of sea-casualities, the traffic volume, the frequency fuzzy day, and the complexity of waterway are selected as the item of evaluation, and the fuzzy measure are applied to the evaluation of 8 candidated regions such as the adjacent area to the port Inchen, Kunsan, Mokpo, Wando, Yosu, Pusan, Pohang, Donghae. As a result of evaluation, the priority as to the candidated regions is obtained, and the following prior execution regions, namely, the adjacent area to the port Pusan, Yosu, Mokpo & Wando are selected by considering the present situation, but, in the long run, the VTMS should be executed in the whole coast of the nation, through the cost-effectiveness analysis.
