The purpose of this study is to design and implement a maritime telemedicine system to provide the best medical service for patients who rescue and happens in sailing ship. For this purpose, INMARSAT and MVAST, which are necessary communication channels for maritime telemedicine, were examined and diversity in maritime communication path was suggested. It was implemented to enable maritime telemedicine by linking smart devices and medical devices for physical examination. The marine telemedicine system adopts the HTTP communication protocol to configure the web server and process the client request. The patient's chart information was entered using an application for AndroidPad and the patient was diagnosed using Bluetooth electronic stethoscope for diagnosis. This system enables appropriate medical treatment to emergency patients at maritime, which ultimately can improve medical services. It is expected to be a more effective medical support system through linkage with various medical equipment.

OSGi(Open Service Gateway initiative) Alliance는 1999년에 썬 마이크로시스템즈, IBM, 에릭손 등에 의해 구성된 개방형 표준 단체로 지능형 분산 컴포넌트와 원격 관리 될 수 있는 자바 기반의 서비스 플랫폼을 제정 해왔다. OSGi의 핵심은 어플리케이션의 생명 주기를 OSGi 플랫폼 위에서 어플리케이션이나 번들 컴포넌트의 재부팅 없이 실시간으로 설치, 시작, 정지, 업데이트, 제거를 할 수 있도록 지원해 주며, OSGi는 또한 어플리케이션에 포함될 수 있는 형태의 SOA를 구현하고 있다. 본 연구에서는 OSGi가 현재 홈 네트워크에서 많이 사용되고 있는데 그 방향을 자동차 내부의 네트워크 환경에 중점을 두어 실제로 어떤 서비스가 가능한지 시뮬레이션이나 간단한 서비스를 제작하여 알아본다.

Existing web based information service system solutions show limitations in mobile information services, as well as problems such as uncertain error messages, and difficulty providing swift assistance or real time emergency support. In order to solve these deficiencies, a realtime wireless remote control system has been designed and implemented in this thesis, which is capable of managing and monitoring remote systems using mobile communication devices (Mobile Phone, PDA, Smart Phone) for realtime control. Proposed systems are applied at remote places, for instance 'office building', and a nursery school like 'kindergarten'. In the case of implemented at office building, it can be managing and controlling at real time all sorts of the sensor information that are installed at office building system environment through wire(web environment) or wireless(mobile device). In the other case at kindergarten system that are providing the real-time wireless remote control and monitoring system can be monitoring activity of kindergarten children with a mobile phone of authentication user. The security functions of proposed systems include mobile device user authentication and target system access control. The proposed systems allow real-time user authentication function and system access control function that improve the security of resource administrators and mobile device users, and provides not only uninterrupted services, but also real time mobile service environments.

This research investigates a geographical issue as to which factor discovered in the only Japanese telemedicine with regard to social and medical circumstances performs a role as a determinant in regionalization, especially, local areas in Japan. According to the results, strong human networks based on regionalism are mirrored in regionalization and are associated with not only the development and management of telemedicine operations, but also the choice of telemedicine users concretely. In other words, all processes from the suggestion stage of telemedicine to the practical usage or application stage of telemedicine are involved in the existing human networks within one prefecture (the third diagnostic area); further, personal stakes are transferred to public health care services (telemedicine) and their relationships have been formulated by the telemedicine council including local government, medical association, region-rooted companies, core health centers and universities, etc. Accordingly, the telemedicine council responses to the need of telemedicine users immediately and contributes to develop regional health care. Also, telemedicine users have been connected with each other closely before operating telemedicine; accordingly, the human relationships between doctors and patients or among doctors influence the choice of telemedicine serving sites and their behaviors comes down to regional-based diagnosis via the telemedicine system.

Within a context of rapid technological change and shifting market conditions, the education environment requires new paradigm of education delivery. In accordance of such a technological progress, distance education system, which makes the learning take place at anytime anywhere, overcoming barriers of time, or distance, is emerging as a mainstream of education delivery replacing the convectional one way delivery system from instructor to learners. This paper aims to introduce the development principle and algorithm about Instructional System Desgin(ISD) module, a part of a total solution for distance education services. It was developed on Linux, a free Unix-type operating system. Linux supports so various network protocols, sharing the network resources in a smooth way, that it is able to integrate with other operating system very easily, especially with Windows NT or Windows 2000 servers. In terms of quality, it never falls behind the windows products which are commercially available only. It is a right operating system for the such a school environment that is usually limited in budgets. The development environment of the distance education solution to which ISD module belongs is composing of Apache server for web server, lava bean based on components for ISD module, PHP, server-side scripting language, for HTML documents and MySQL for DBMS.

Recently, as the number of smart devices (such as smart TV or Web based IPTV) increases, the way of digital broadcast contents is changed. This change leads that conventional broadcast media accepts Web platform and its services to provide more quality contents. Based on this change, in education field, education broadcasting also follows the trend. The traditional education broadcasting platforms, which just delivered the lecture in one-way, are utilized the Web technology to make interaction between teacher and student. Current education platforms, however, are insufficient to satisfy users' demands for two-way interactions. This paper proposes a new remote collaborative learning platform which able to provide high interactivity among users. Based on new functional requirements from original use case, the platform provides collaborative contents sharing and collaborative video streaming techniques by utilizing WebRTC (Web Real-Time Communication) technology. The implementation demonstrates the operability of proposed system.

기존의 건설지원시스템은 주로 문자정보를 대상으로 구축되어 지형이나 공간정보와 같은 실세계에 대한 정보를 제공하는데 취약점이 있으나, GIS(Geographic Information System)는 이러한 문제에 대해 공간정보의 제공뿐만 아니라 설계지원시스템과 연계하여 효율적이고 체계적인 정보의 분석 및 지원 기능을 제공해 줄 수 있을 것으로 기대된다. 이에 더하여 다양한 네트워크의 구축 및 이를 통한 정보서비스의 발전은 GIS의 제공방식과 내용을 변모시키고 있으며 네트워크 상에서 즉각적으로 사용자에게 다양하고 동적인 GIS 솔루션을 제공할 수 있는 Web GIS의 활용이 확산되고 있다. 본 연구에서는 건설진행상황을 즉각적으로 확인하고 실시간으로 업무보고 및 업무지시를 수행함으로써 원격공정관리를 가능하게 하고, 나아가 단지 문서적인 업무보고에만 의존하여 보고자의 의도에 따라 수동적으로 의사결정을 내리던 관행에서 벗어나 Web GIS에 기반한 건설공사 정보관리시스템을 개발함으로써 건설공사 현황을 직관적으로 판단하고 의사결정을 내릴 수 있는 시스템을 구축하였다.
