On the advent of digital era, ECDIS has emerged as a new navigation aid that should result in significant benefits to safe navigation. More than simply a graphics display, ECDIS is a new concept navigation system capable of providing integrated information of geographical and texual data. As an official vector data for ECDIS, ENC consists of spatial and feature data to describe objects in form of points, lines and areas. IHO published International Standards for ENC, such as S-52(Specification for Chart Content and Display Aspects of ECDIS and S-57(IHO Transfer Standard for Digital Hydrographic Data). This paper deals with the implementation of an EUC representation system which meets S-52 presentation specification and S-57 transfer standards by analyzing S-57 data structures and converting then to an appropriate internal data structures and representing them onto screen adopting S-52 presentation specification.

The ENC standard, S-57 Specification was established to exchange hydrographic data between it's users such as HOs ECDIS users, etc. The digital navigation chart which is produced according to the S-57 Specification is called an ENC(Electronic Navigational Chart) and the SENC(System ENC) is a by-product of ENC suitable for computer graphics system Even though the efficient structure of SENC is a key element of measuring ECDIS performance, the amount of papers about these topics are small compared with other research fields. In this paper, the author designed an efficient spatial data structure of SENC, called Mesh This paper also includes the implementation result of the 'Mesh' which displays SENC on computer screen.

The objective of this paper is to describe the result of development of collision avoidance supporting system, based on the electronic chart display and information system(ECDIS). In real ship operations, collision accidents happen frequently due to human errors such as the lax vigilance, misinterpretation of international regulations for preventing collisions at sea (COLREGs). We developed a system which will help to avoid these kind of accidents. This system can automatically recognize the risk of collisions, generate the safe alternative routes that comply with COLREGs, and then deliver the results into auto pilot. A virtual simulation assuming progressive collision situations revealed the usefulness of this system.

본 논문에서는 향후 의료분야에서 활용하게 되는 표준화 기반기술을 개발함을 주된 목표로 HL7 메시지 서버 구축에 필요한 소프트웨어 프레임워크의 디자인 및 구현에 대해서 기술하였다. HL7 표준은 의료 환경에서의 전자적 데이터 교환을 위한 이벤트 중심의 어플리케이션 프로토콜로서, 메시지 단위로 정보의 전송이 이루어진다. 이와 같은 의료정보 교환의 기본 단위인 HL7 메시지를 만들기 위해서 연구진들은 중간 계층의 인터페이싱 방식의 유효성을 고려하여 인터페이스 엔진에 해당하는 HL7 메시지 서버를 구축하였다. HL7 메시지 서버는 병원점보시스템에 연결되어 약속된 이벤트가 발생할 때마다 해당하는 HL7 메시지를 자동적으로 생성하는 서버 시스템으로서, 현재 운영되고 있는 국내병원정보시스템에 HL7 표준을 쉽게 적용시킬 수 있는 최적의 솔루션을 제공해 줄 것이다.

Electronic Navigational Charts(ENCs) are a database for the use of supporting the safety of navigation in marie voyage embedded within the navigational information in the Electronic Chart Display & Information System(ECDIS). Recently IMO made a decision on the mandatory equipment resolution of ECDIS for the international SOLAS vessels until 2018. With this regulation intention together the spontaneous uses from the wide range of marine applications are accelerating the increasing demand for ENCs at both of the navigational purpose and the non-navigational purpose. But there seems to be not enough guidelines or systematic approach for the service of the non navigational purpose. This paper deals with ENCs distribution issues. We present a integrated solution for the ENCs service of both user domains and also demonstrate the implemented results.

ENC(Electronic Navigational Chart) is an electronic chart including all kinds of information of nautical chart. Mariners have difficulty reading information because of clutter problem if display scale of ECDIS is lower than compilation scale of ENCs. IRO made SCAMIN improvement model included in S-65 Standard to settle this ENC clutter problem. This SCAMIN model includes both simple restriction that should satisfy some requirement and share geographic information, and hard restriction that should overlap with area object such as depth area, land area, dredge area. It also apply SCAMIN step of sounding value according to importance of safety navigation. In this paper, we analyzed the restrictions for SCAMIN model of S-65 Standard, developed algorithm and application to apply theses restrictions reasonably and mechanically. Also we applied this algorithm and application to Korea ENCs and evaluated the result of performance.

전기.정보계열의 학과에서는 기초 과목으로 전자기학, 회로이론, 양자역학, 통계역학, 수학 따위인데, 정보 관계에서는 전자기학보다도 소프트웨어공학에 도움이 되는 과목을 4년간 교육해야 한다. 4년간이라고 해도 실질적으로 2년 반이므로 대학의 4년간이라는 것은 상당히 큰 문제를 안고 있다. 대학원 진학이 늘어가는 추세에서 학부만 마친 학생도 있으므로, 이것에 대해서는 산업계의 필요성을 받아들이는 동시에 산학 공동 또는 산관학의 협력 체제를 갖추어야 한다. 따라서 산업계와 대학이 일체가 되어 대학의 교과과정을 토의하는 자리를 마련해 교육 시책에 반영하는 것이 필요하다. 상호가 협력하는 시스템, 산업계와 대학이 융합할 수 있는 프로그램을 학회를 중심으로 한 중립의 자리에서 만들 필요가 있다.

Electronic Navigational Charts(ENCs) are official nautical charts which are equivalent to paper charts with supplementary information. Although their main purpose is to be used for the safe navigation of ships, they also contain much information on coasts and seas which may be interesting to ordinary people. However, there is no easy way to access them because of their specialized data format, access method and visualization. This paper proposes m implementation of SVG for the access and services of ENCs. SVG(Scalable Vector Graphic) makes it possible to make use of Vector graphics for map services in basic internet browsing environment. Implementation of SVG for ENC applications by this research is free of special server side GIS mapping system and client side extra technology. The Implementation of SVG for ENC Applications can be summarized as follows: Firstly, SVG provides spatial information to possess searching engine to embody SVG map. Secondly SVG can provide high-quality vector map graphics and interactive facility without special Internet GIS system. It makes it possible to use services with very low cost. Thirdly, SVG information service targeting on maritime transportation can be used as template, so it can be used dynamically any other purpose such as traffic management and vessel monitoring. Many good characteristics of SVG in mapping at computer screen and reusability of SVG document provide new era of visualization of marine geographic information.
