This paper proposes to include engine information in Maritime Service Portfolio (MSP) for effective implementation of e-Navigation. Even though engine information is one of most important element to e-Navigation, MSP consists of mainly about navigation and communication information not included engine information. Furthermore, in reality, engine information sent from ship side such as mainly noon report and Planned Maintenance System (PMS) is too limited to make e-Navigation possibly. Therefore, Remote diagnostic structure receiving and sending data of engine information must be included in MSP for implementation of e-Navigation. Also, it has to be designed, and developed by Software Quality Assurance (SQA).

This paper describes an application of information presentation based geographic map for maritime information, including navigation information. The work is motivated by the need to prepare maritime information representation and distribution for future generation Web network technology. This works consist of map generation using GML and application to maritime information. GML 3.0 became an adopted specification of the Open Geospatial Consortium(OGC) in January 2003, and is rapidly emerging as the world standard for the encoding, transport and storage of all forms of geographic information. This paper looks at the application of GML to one of the more challenging areas of maritime information. Specific features of GML of interest to maritime information provider are discussed and then illustrated through a series of maritime information case studies. The first phase of the work consists of the construction of GML application schema for using as a base map of maritime information. Maritime information is acquired from multiple sources, including standards documents, database schemas, lexicons, collections of symbol definition. The sources of GML ontological knowledge and the contribution of each source to the overall ontology are described in this paper. In the second phase, the prepared GML is used to create a prototype of the mixed maritime information as a base map - for tagging documents within the maritime domain. An overview of this prototype is included. One application area for these information elements described here is the integrated retrieval of maritime information from diverse sources, ranging from Web sites to nautical chart databases and text documents.

The International Maritime Organization has determined that more than 80% of maritime accidents are caused by human error. A variety of methods have been considered to reduce maritime accidents caused by such human error. Navigators operate by observing surrounding maritime situations and analyzing information using various navigational devices. This study proposes a system to ensure safe navigation by assisting navigators through the delivery of maritime safety information (MSI) between land and sea. In the future, supplementing the system through long-term on-the-ship tests is necessary by defining MSI in relation to maritime service portfolio regions.

With international urgence of terror situation, many methods of terror techniques and skills are appearing and more intense and threatening terror is braking out not only in the air(plane), but also in the sea(ship). Korea is surrounded by 3 sides of sea and is a proud maritime nation that should advance to foreign country through the sea because South Korea and North Korea are confronting. Korea depend on the maritime transportation, 99.7% of exporting, importing material resources. Therefore, acquisition of the marine safety has the great affect on national security and economical life. On the high tension of situation about threat and possibility of maritime terroism, the potential ways of the improvement policy for counter-tactics against big maritime terror are the following. First, we should construct clear and well-organized network for accurate information about maritime terrorism Second, we should have the information of all domestic, foreign passenger's ships Third, national important facilities such as atomic energy plant, thermo-electric power plant, shipyard need policies to manage all emergency situation Fourth, government authorities should improve tactic abilitities by competing with support and budget inside of nation as well as outside of nation. To develop big maritime terror of our country, we will have to hold cooperative training & tactics contest of big maritime terror by cooperating educational industry organization with similar institute, improve the ability of members of big terror and acquire tactics information by excavating and exchanging a new technique through tactics seminar and public hearing.

지능형 해상교통정보서비스(바다내비)는 선박에 설치한 LTE-Maritime 송수신기 및 AIS 등의 선박 장비로부터 육상 센터에 주기적으로 수집한 선박들의 위치 정보 기반으로 선박의 충돌·좌초 등을 예방할 수 있도록 실시간 예방 정보를 선박에 제공한다. 그러나 위 서비스는 선박의 위치를 측정하는 GPS 위치 정보가 LTE-Maritime 또는 AIS 망을 통해 전송되는 과정 중에 끊기거나 위치 튐 및 지연 등의 현상이 발생할 수 있어 선박 위치 정보의 신뢰성을 떨어드릴 수 있다. 본 연구는 확률에 기반한 최적 추정 필터인 칼만필터를 이용하여 기존 수신 위치정보를 기반으로 선박 위치 예측을 통해 비정상 구간에서도 어느 정도 신뢰성 있는 위치 정보를 추정하는 것을 목표로 한다.

해상교통정보의 수집, 관리 및 공유를 개선하기 위해서는 해상교통정보 관련 기술 동향 파악 및 해상교통정보의 현황·문제점 분석이 우선되어야 한다. 따라서 본 연구에서는 먼저 해상교통정보의 국내외 기술 동향을 조사하였으며 국내 해상교통정보의 수집·관리·공유에 대한 현황·문제점을 분석하여 정리하였다. 자료를 토대로 문제점을 분석한 결과 우선 수집단계의 문제점은 주로 LTE 통신권을 벗어나는 원거리 RADAR·CCTV·카메라 영상정보 수집의 어려움으로 나타났으며 이로 인해 EEZ를 거쳐 영해로 진입하는 밀입국 선박 등의 조기 탐지가 어려운 것으로 나타났다. 그리고 관리단계의 문제점은 대부분 해상교통시스템이 자체 구축한 물리 저장 공간을 사용함으로써 저장 공간의 유연성 부족으로 인해 편리한 축소·확대가 어렵고 시스템 장애 발생 시 대비책으로 시스템 이중화·백업 등이 힘든 상황이다. 또한 공유단계의 문제점은 대부분 해상교통정보 공유시 주로 내부망을 사용하고 있는 현황상 운영기관 외부로의 정보 공유가 어려운 것으로 나타났으며 LRIT·SASS와 같이 정부 클라우드를 통해 정보 공유가 되고 있다고 하여도 정부 클라우드의 특성상 해양 빅데이터 등을 효과적으로 활용할 수 있는 다양한 애플리케이션의 제공이 원활히 되고 있지 않은 상황이다. 이러한 문제점들을 개선하기 위해 우선 수집단계의 경우 무인기·위성 등 수집장비의 추가 구축을 제시함으로써 수집구역을 확장하였고 관리·공유단계는 각 해상교통시스템의 운영 주체·정보 공개성을 고려한 민간 클라우드 도입 및 구축형태를 제시함으로써 클라우드 도입 시 전문성·보안성 향상을 기대하였다.

This research is based on the information compiled on the occurrence of maritime casualties onboard ships registered under Central American Region (CAR) flag States. Due to nonexistence of writing reports in anyone of the countries that are integrating this Region, the information was compiled by the author through personal communication with the people involved in the casualties. The information was compiled by typing up the text and digitizing on the computer for the respective data base. For each casualty occurred, the following information was compiled, date and type of the casualty, position of the ship at the time of the casualty, dimension of the ship, number of people affected by the casualty, and cause and consequences of the casualty. Based on the number of people affected (death and disappear) by the casualties occurred was calculated the mortality rate by 100,000 persons and then compared with the Japanese mortality rate. Furthermore were analyzed the CAR maritime authorities competences and then were compared to that the Japanese counter part. In addition, the implementation rate of the International Maritime Organization (IMO) and International Labor Organization (ILO) conventions ratified by the CAR countries were analyzed. The objective of this research was to compiled and analyze the occurrences of maritime casualties happened on board the ships registered under the CAR Flag States, in order to determine the causes of these accidents. The results of the analysis enable us to better understand of the maritime safety situation of the ships that are registered under the CAR flag States. In order to reduce the occurrence of maritime casualties are proposed a series of measures based on the differences found then the comparison between CAR and Japan. Based on the results of this research, is possible to conclude that the inaccessibility of atmospheric information and the lack of safety measures onboard has been the main cause of the maritime casualties happened in the Pacific side of the CAR.

Information on maritime boundaries is essential to manage ocean and fisheries effectively in the era of the UN Convention on the Law of the Sea. With various information regarding to maritime boundaries analysed and reviewed, maritime boundaries are mainly divided into two categories such as international and domestic boundaries and also sub-divided into two aspects such as administrative and other boundaries. After clarification of boundary information, the geographical natures of boundaries, for instance datum, projection, line types, are reviewed. The Geographic Information Systems (GIS) is used for the establishment, management and utilization of boundary information due to its strong function in database, analysis, visualization, etc.
