Recently, researches of technology and standardization for maritime safety are proceeding internationally. In particular, some technologies and strategies for e-Navigation have been developed and the necessity of development of next generation VTS (Vessel Traffic Service) has been raised in Korea. In order to construct user oriented VTS system for domestic environment, VTS operators are asked for their requirements related to developing VTS and the opinions should be reflected in the VTS. So in this paper, we collect the requirements from fifteen VTS centers in the country and we also analyze them. Furthermore, we propose an ASM (Application Specific Messages) service, which was not supported by current VTS, and we verify the proposed ASM through AIS (Automatic Identification System) system and simulation terminal for maritime safety.

선박 운항 안전을 위한 기술은 선박 자체뿐만 아니라 육상 해상교통관제 시스템(VTS)에서도 매우 중요한 역할을 수행한다. 최근 국제적으로 e-Navigation을 지향한 최신 IT기술을 반영한 새로운 안전운행을 지원하기 위한 VTS 항행 지원 기술개발이 활발하게 진행되고 있다. 이러한 국제적 변화와 더불어 최근 국내외에서 AIS의 확장인 ASM을 통한 신규 서비스 제안이 활발하게 이루어지고 있으며, 해당 서비스를 시범서비스하고 이를 국제 표준으로 추진하고자 하는 업체와 IALA 등 해당 그룹들이 계속 증가되고 있다. 특히 국내에서는 VTS의 개발을 추진하고 있으므로 기존의 VTS에서 제공하지 않았던 ASM 서비스를 제안하고 이를 구현하여 시뮬레이션하여 가능성을 검증하고자 한다. 따라서 본 연구에서는 이러한 항행지원을 증가하는 e-Navigation 환경에서 국내 VTS 시스템에서 적용 가능한 방안을 연구하고, 이들을 비교하여 실제 적용할 수 있는 기술개발 방향을 정립하고자 한다.

In this paper, we propose the information acquisition and analysis system for a vehicle driver in order to provide the safe driving environments. We first define the list of reckless driving behaviors and propose the recognition system, which recognizes the reckless behaviors, by using the acquired information. The collaboration among the information acquisition, the analysis, and the behavior comparison modules increases the accuracy of the recognition rate. Our system alarms to a vehicle driver in order to notify the potential to confront the dangerous situation due to the abnormal or reckless driving behaviors.

선박의 대형화와 고속화 및 늘어나는 해상 뮬동량으로 인해 해상에서 대형사고의 위험이 증가하고 있다. 해난사고의 위험을 억제하고 선박의 안전과 해상환경의 보호를 강화하기 위해 기존 레이더 위주의 관제시스템을 국제적 e-Navigation기반의 다양한 항행정보지원 및 최신 유비쿼터스 기반의 센싱 장비들에 의한 기술과의 융합을 통하여 보다 지능화되고 첨단화된 차세대 해상교통관제시스템(u-VTS)의 도입이 필요하게 되었다. 국제표준에 부합하는 차세대 해상교통관제시스템(u-VTS)을 개발하기 위해서 국제동향의 분석이 필수이며, 이 연구에서는 VTS 관련 국제회의에서 현재 논의 중인 내용을 소개하고 상용화될 기술에 대하여 조사했으며, u-VTS에서 제공되어야 할 서비스를 도출했다.

International Hydrographic Organization(IHO) adopted standard S-100 as the international standard Geographic Information System(GIS) that can be generally used in the maritime sector. Accordingly, the next-generation system to support navigation information based on GIS standard technology has being developed. AR based navigation information system that supported navigation by overlapping navigation information on the CCTV image has currently being developed. In this study, we considered the application of a transparent display as a method to support efficiently this system. When a transparent display applied, the image distortion caused by using a wide-angle lens for parallax secure, and the disc s, and demonstrated the applicability of the technology by developing a prototype.

In the next generation system, a study on realization of Multi-Core system is in progress for applying it in multi service network. Therefore some mobile systems are expected to be appeared. These systems can support WiBro, WCDMA, CDMA, etc with single terminal. These systems have to support various FA using broadband frequency and hand over to other service network. Especially, in the telecommunication system composed of cell, the transmit power can be interference at adjacent system, has effect on system channel capacity and cell size. In this paper, we improve the unstable transmit power caused by unsettled system operation, propose the RF(Radio Frequency) Calibration method which can use the transmit power stably even during hand over between heterogeneous networks causing unstable power change. Also we used proposed method and analysed used electricity of system during hand over between heterogeneous networks.

I&C (Instrumentation & Control) system is different from information system and the security design of the two systems are also different. The modeling activity is needed based on the security control guide in order to build I&C system security control. In this paper, the role and by the security control, we designed the relationship (that is, the relation schema) between the documents for 'The system for supporting the cyber security control of I&C system design' based on the security control guide. The designed schema plans 'The system for supporting the cyber security control of I&C system' for observing the security control guide, and is used as the database and content that supports its design and implementation. The process and system of the proposed schema is utilized and designed. The design of the schema and system is intensified in the design phase with the proposed mode and supporting the I&C system cyber security design.

Recently, there has been much interest in the converged platform that enables the harmonized collection, integration, exchange, presentation and analysis of various kinds of marine information by using the ICT means. Regarding such the converged platform, S-100 standards including the international hydrographic data model are being announced and various studies have been published based on the S-100 standards. However, the existing studies have presented simple solutions for only given problems on the converged service of the maritime information. They could not propose the design concept of the converged platform which makes it possible to provide the standardized and integrated services among the geospatial data, the real-time maritime data, and the next ENC. Therefore, we propose design and implementation details of the converged service platform for the geospatial and the maritime data based on the S-100, WMS, WMTS, WPS, SOS standards. The proposed platform has advantages of supporting both the S-57 and the S-101, supporting the converged services of heterogeneous geospatial data and ENC data, supporting the real-time services of sensor data such as weather, AIS, and CCTV, and supporting the development of various kinds of maritime systems such as ECDIS, ECS, VTS based on the WebApp service. Finally, we proved the effectiveness of our proposed platform through the actual implementation of the converged service of geospatial data, S-101 data, and KWeather data.
