As a preliminary study of enter or leaving traffic patterns of the Korea main port, port Management Information System (Port-MIS) data was used to check the volume of vessels entering and leaving the port of Busan, and three consecutive days from each seasons were selected for study. Selected 12-day General Information Center on Maritime Safety & Security (GICOMS) data was also used to analyze the traffic pattern in the main traffic lane of Busan port for dangerous goods carrier. Also, the distance between dangerous goods carriers and Oryukdo breakwater of east breakwater in the main traffic lane was analyzed. Collision probability was estimated using the cumulative probability distribution function of the normal distribution for the maritime traffic safety audit scheme based on the assumption that a ship's trajectory has a normal distribution for a section of the route. However, in case of entry or leaving thorough the Oryukdo breakwater and entry thorough the east breakwater, ship's sailing trajectories were revealed not to follow a normal distribution via regularity testing using a KS-test and SW-test. Especially in the north port, the tendency of the right side of the ship to pass was remarkable. It is desirable to develop a traffic model suitable for the characteristics of the port rather than to apply general traffic theories, and to apply this model to a maritime traffic safety diagnosis, so further research is needed.

Although it is expected to provide fundamental data for advanced VTS system by analyzing traffic accidents in VTS area, there is no quantitative analysis to find it.. In this research, it is examined and analyzed marine casualties records(1999-2004), data of Port-MIS and data of each VTS center. The results of this research are as below. 1) It is necessary to reduce traffic accident and to improve VTS operating system. 2) It is discovered for statistical discrepancy between vessels controlled by VTS and vessels not controlled by VTS in accident cause, visibility, perception distance and cause of late perception in collision accidents 3) It is necessary for VTS assistance to be positive and to made in ample time consecutively. 4) As the result of traffic accident prediction model, it is necessary to develop a system improving VTS operators' ability to identify dangerous ships.

Since 1996, the document exchange method by EDI has been introduced in port and logistics industries to enhance the declaration activities to the Pusan Port Authority and Customs. In spite of these efforts, users such as shipping companies, shipping agents, and freight forwarders have complained the inconvenience of using EDI systems. The major reasons can be summarized as too much transfer time, inconvenient EDI software, and problems on message receiving confirmation. To solve these problems, although we have developed an Internet based EDI system for Port-MIS users, we have failed its implementation practically for the short of Governments readiness, the complexity of systems and separation with in-house systems. So, the writers have changed the direction of research to applying the concept of SCM to logistics system by XML/EDI. In this Paper, the prototype systems to integrate processes of shipping company, Port Authority, Customs and stevedoring company will be suggested. The new method of EDI gives us advantages, which are the accuracy of cargo data and integration of processes among firms and keeping the service of cargo trace.

VTS에서 정보제공실적은 대내 외적으로 많이 활용되며, VTS 성과평가 자료로 중요하게 활용되고 있다. 지금까지 VTS에서 산정되는 정보제공 실적은 대부분 관제사가 관제업무 중 정보제공 발생시 관제일지에 수기로 기록하고 있으나, 선박관제 및 선박모니터링, PORT-MIS 등 여러 업무를 수행하고 있는 관제사가 정보제공 실적을 일일이 기록하는데 한계가 있다. 본 연구에서는 객관적인 정보제공 실적 산출을 위해 VHF 음성 자료 및 선박간 조우데이터를 분석하여 선박교통데이터 기반의 선박 안전정보 제공 회귀모형식을 도출하고자 한다.

In order to become a mega hub port, major ports all over the world are making every effort to enhance their productivity through efficiency of internal operation. Accordingly, in order to enhance the competitiveness of a container terminal, an automated container terminal is considered as the best alternative. An automated container terminal is using such automated handling equipment as AGV(Automated Guided Vehicles) and ATC(Automated Transfer Crane). The efficient equipment operation plays a critical role in enhancing the productivity of an automated container terminal. In an automated container terminal, the most important equipments are AGV and ATC. Each block of containers with a vertical layout is generally operating two ATCs. The two ATCs can be crossed or not at each block. In the case of operating crossover ATC, it has an advantage of high flexibility that ATC work is possible at both TP(Transfer Point) of each block. But it has also a disadvantage that the yard has to be operated at a low storage level of containers in the terminal yard. Recently, for automated container terminals, which are being prepared for opening in Korea, they plan to use uncrossed twin ATC in order to make the storage level of their yards high at a low cost. Therefore, studies have to be made in order to increase the efficiency of twin ATC system based on the flexibility that the crossover ATC system has. This research aims to suggest an operation strategy to improve efficiency of twin ATC at each storage block in a yard.

본 논문에서 기존의 항만물류 EDI가 가진 문제점을 해결하기 위한 방안으로 제시된 XML/EDI에 대해 살펴보고, 항만 물류에 XML/EDI를 적용하기 위해 기존의 EDI 메시지를 처리하기 위한 브라우저를 개발한다. XML 문서의 논리적인 구조를 표현하는 방식에 DTD(Document Type Definition)과 XML Schema가 있는데, 여기서는 다양한 데이터 타입를 가지고 있는 XML Schema를 사용해 EDI메시지의 구조를 표현한다. 또한 XML/EDI는 인터넷을 기반으로 하므로 웹을 통해 EDI 메시지를 교환하고자, 메시지 포맷으로 XML을 사용하며, 통신방법은 HTTP를 사용한다.

Korea has a systemic problem with lack of engine maintenance, especially among the Commercial Fishing Vessel fleet. This results in a inordinate percent of SAR call-outs for vessels with engine failure. These SAR call-outs lead to a free tow to shore by KCG or by one of its volunteer associates. Although these tows are not a terrible economic burden on KCG, it is a burden in terms of time and resources mis-allocated. This paper proposes a Commercial Fishing Vessel Examination (CFVE) program modeled after the program run by USCG. It is expected that adopting the CFVE program, KCG may be able to create a culture of safety among fishermen; thus, replicating the USCG's success rates.
