Lately, trend is change to concept that management traffic of ship is magnified gradually to near shore waters from harbor. Therefore, introducing the AtoN AIS technology that install AIS in the ground station, lighthouse, bouy, sea facilities etc.. that is support equipment for safety sailing of ship and safety security of harbor and ship administration. The operation and maintenance of AtoN AIS are required to efficient method. With this actuality, sea advanced nation They has been apply for developing AtoN AIS equipment that is connected equipment of technology standard in IALA. Because of it is expected to depend equipment in income, that is required to domestic technology of the AtoN AIS. This paper is targeted to development that is suitable automation AtoN AIS equipment in environmental peculiarity for construnstrunstrAtoN operating administration center. It has been realization the interface module for control and monitoring system and the communications protocol for information interchange.

Recently the construction of bridges crossing navigable waterways is being promoted aiming at expanding social infrastructure and optimizing the overland routes through private investment. The construction, however, tends to focus on more the commercial requirements than the marine safety and efficient port management that it has a big risk not only to fail in ensuring the safety of ship traffic, but also to muse some severe conflicts between the parties concerned. These problems result from the lacking of standards about the design guidelines and discussing process considering the marine traffic safety when designing bridges. This research attempts to show the problems mused by bridge construction and suggest the standard discussing process through the survey and process analysis on Kwangyang Bridge and Incheon Bridge.

VTS operators may suffer from acute, chronic, or traumatic stress caused by their workload and working environments associated with task or combination of task. This study intended to measure the level of VTS operator' stress and find out factors influencing it by understanding their characteristics during carrying out their task. For this purpose, analyzed the data collected through conducting survey on VTS operators as the Korea Occupational Stress(KOSS) and Psychological Well-being Index(PWI). As a result, VTS operators are experiencing higher level of psychological stress than the national average. And the factors to cause VTS operators' occupational stress can be summarized as follows; working environment factors, shift work especially night duty, workload, etc. This study provides the fundamental information for understanding human factors of VTS operator' occupational stress.

기후변화로 인한 거대 자연재해 발생의 위험이 지속적으로 증가하고 있으며, 국외의 경우 주요정부기관, 보험사 및 연구기관 중심으로 자연재해 피해예측 모델을 개발하여 사용하고 있다. 침수사고 인한 피해는 건물은 물론이고 가재도구, 재고자산, 기계시설 등의 내용물에서도 발생하며, 건축물 신축단가 등을 이용해 비교적 쉽게 자산가치를 산정할 수 있는 건물구조물과 다르게, 건물내용물의 자산가치는 시설물의 업종, 용도, 사용자 특성 등에 따라 변동성이 큰 특징이 있다. 내용물의 피해액 추정을 위해 자연재해 피해예측 모델은 건물 구조물과 내용물 가치의 비율인 CSVR(Contents to Structure Value Ratio)을 사용하며, CSVR은 시설물 용도에 따른 자산가치평가 통계를 이용해 산정할 수 있다. 충분한 자산가치평가 DB를 확보할 경우 CSVR의 정확도 확보가 가능할 것이며, 이를 위해 국내에서는 민간보험사의 재물보험 계약 4만여건의 건물, 내용물 보험가입금액을 행정안전부 도로명전자지도에서 분류하는 건물 용도에 따라 분석한 연구결과가 있다. 하지만, 일반적으로 보험가입단계에서 대략적으로 추정하는 보험가입금액과 실제 자산의 가치는 차이가 있을 수 있지만, 보험가입물건의 실제 자산가치는 일부만 DB화 되어 있는 단점이 있다. 본 연구에서는 사고 발생 후 작성되는 손해사정보고서에서 평가한 정확한 자산가치 DB를 수집하여, 보험가입금액을 기준으로 산정한 CSVR의 결과와 비교하였다. 손해사정보고서에서 평가한 실제 자산가치를 기준으로 분석한 CSVR과 보험가입금액을 기준으로 산정한 CSVR은, 업종에 따라 유사하거나 큰 차이를 보이는 경우도 있었으며, 침수로 인한 정확한 피해액 추정을 위해서는 보다 양질의 DB확보를 통한 CSVR의 정확도 확보가 필요한 것으로 분석되었다.

Recently, the navigation risk is increasing significantly with growth of marine traffic volume and construction of marine facilities, water bridges, port development and marine wind farm etc. To reduce this kinds of risk, Ministry of Land, Transport and Maritime Affairs enacted a new law called MSA(Maritime Safety Audit) as a comprehensive maritime traffic safety management scheme in order to ensure safety improvements from the early planning stage to post managing of the development which affect the maritime traffic environment. MSA as a tool for improving maritime traffic safety is a formal safety assessment in the existing or future ship's fairway by an independent audit team. It examines the potential hazards of maritime traffic safety, if necessary, and is to ensure the implementation of appropriate safety measures. The object of this paper is to comprehensively evaluate the achievements and implementation problems of MSA about the 2 years, to define the fundamental problems of MSA by conceptualizing and analyzing MSA limits. MSA requires further examination about the introduction of screening and scoping in order to increase the efficiency and objectivity. It will be required the measures concerning policies directions as a tool for planning process for project owner. It will lead to right understanding concerning audit scheme and used in various ways such as amendments to related law.

항로표지는 해상교통의 안전을 도모하고 선박운항 능률 향상을 위하여 설치된 해양교통안전시설 중 하나이다. 그러나 선박 또는 기상악화 등의 이유로 발생하는 항로표지의 사고로 인하여 제 기능을 상실 하였을 경우, 선박운항자나 이용자가 느끼는 선박통항 위험도가 증가할 가능성이 높다. 따라서 본 연구에서는 우리나라 최대 항만인 부산항을 중심으로 부산항 이용자를 대상으로 항로표지 및 표지사고에 대한 인식조사를 실시하여, 효율적인 항로표지관리방안을 제시하고자 한다.

Marine transportation facility is public goods for the general public and their safety. The study used the Contingent Valuation Method (CVM), a method to estimate economic value of non-market goods, such as environmental goods. In order to analyze economic effects of marine accidents preventable by the VTS, the study estimated costs caused by marine accident cases. It conducted surveys with people and shipping companies in local areas where VTS is to be established in the future. According to a survey with people in areas where marine transportation control center is to be built (Tongyoung), the yearly benefit from building new VTS is estimated at KRW 11billion. If fees are paid in the form of income tax for five years from 2014, corresponding benefits during the same period will reach KRW 47.3 billion in current value. An analysis on economic validity of VTS establishment in Tongyong showed the B/C ration stood at 3.193, far higher than 1. The Net Present Value (NPV) was KRW 32.5 billion and the Internal Rate of Return (IRR) turned out to be 37.4% which was higher than social discount rates of 53.5%. On balance, the establishment has reasonable economic validity.
