This paper proposes the architecture and the methods of security network management for auto-configuration of security systems by extending the existing policy-based network management architecture. The architecture and the methods proposed in this paper enable a security management sewer to automatically decide the best-suited security policy to apply to a security system and the most effective and efficient security system to perform security policy rule, based on the role and capability information of security systems and the role and time information of security policy. For integrated control of network system and security system, this paper also proposes SNMP protocol based security network topology map generator. To show the excellence of the proposed architecture and methods, we simulate and evaluate the automatic response against attacks.

The telematics positioning testbed is an infrastructure to test and verify positioning technology, the sub-component of telernatics system. The positioning testbed provides the environment of performance analysis for acquisition of static and dynamic positioning information using telematics vehicle. This testbed consists of onboard positioning system, positioning reference station and lab positioning server. The onboard positioning system equipped in telematics vehicle, consists of target positioning system, reference positioning system, and analysis tool. A equipment acquiring high precision positioning data obtained from GPS combined with IMU was set as a reference positioning system. Analysis tool compares observed positioning data with high precision positioning information from a reference positioning system, and processes positioning information. Positioning reference station is RTK system used for reducing atmosphere error, and it transmits corrected information to reference positioning system. Positioning server which is located at laboratory manages positioning database and provides monitoring data to integrated testbed operating system. It is expected that the testbed supports commercialization of telernatics technology and services, integrated testing among component technology and verification.

e-Navigation requires shipboard integrated information system to manage several kinds of data on shipboard. IEC 61162-450 may be adopted for the development of such system. Based on IEC 61162-450, this paper proposes an architecture of shipboard integrated information system, and describes a developed system. The system is composed of NMEA 2000 gateway, wireless sensor gateway, database, monitoring applications. This paper also shows the feasibility of the system through some tests.

A number of wireless technologies have been implemented, but each technology has its limitation in terms of coverage and bandwidth. WLAN and 3G cellular network has emerged to be a complementary platform for wireless data communications. However, the mobility of roaming terminals in heterogeneous networks poses several risks. To maintain secure communications in universal roaming, the effective authentication must be implemented. The focus of this paper is on analysis of authentication architecture involved in integrated WLAN/3G networks.

In this paper, MIlS (Medical Image Information System) has been designed and implemented using INGRES RDBMS, which is based on a client/server architecture. The implemnted system allows users to register and retrieve patient information, medical images and diagnostic reports. It also provides the function to display these information on workstation windows simultaneously by using the designed menu-driven graphic user interface. The medical image compression! decompression techniques are implemented and integrated into the medical image database system for the efficient data storage and the fast access through the network.

In order to improve their hospital services in unlimited competitive situations, the general hospitals, particularly, have since the 1990s been concentrating more on hospital information processing systems and the automation of the patients' convenience. They also give priority to the advance of integrated hospital information systems centred around the patients. Introducing more progressive information technology to already established hospitals, the OPD has been most affected by HIS because there are a lot of patients and doctors. On this background, this study analyse the change of OPD and some related departments around the 1990s with the general hospitals as it's object. It investigates the way of building hospitals and presents some information about the planning of building hospitals.

The purpose of this study is to suggest planning directions of architectural integrates model by analysing the foreign case of integrated services for the aged and the disabled. For this study, we have researched on three different aspects. Three aspects are the element of barrier-free, architectural planning, information technology and operation. Based on the analysis of overseas examples, the good circumstance for both the disabled and the elder as one of member in the local societies could be defined like the following conditions: that is, (1) IT technology facilitates both barrier-free architecture and life to be easier and safer, and (2) both the disabled and the elder in local societies live together with the non-disabled in the same community. To realize this purpose, for a short-term plan, the system of feedback, examining the results of the research through the examples of housing plan, should be improved. In addition to, the system of public service, such as introducing the institutes for social educations, should be developed to result in the change of social insight. For a long-term plan, the whole society should have the research and plan of the unified model in a dimension of cities, where the network of public welfare is deeply associated with the system of the architecture, traffic, streets, and living-supporting information.

The passive type RFID (Radio Frequency Identification) System using Surface Acoustic Wave (SAW) tag at 900 MHz in the range of more than 1 m was fabricated. To improve interrogation range of the system propose a method to increase isolation between transmitter and receiver. This method using a direct conversion architecture achieves a leakage rejection of 10 dB increased compared with conventional system. Measured interrogation range is more than 1 m.

Various computing systems are used in naval ships. Since each system has a single purpose and its applications are tightly coupled with the physical machine, applications cannot share physical resources with each other. It is hard to utilize resources efficiently in conventional naval shipboard computing environment. In this paper, we present an integration architecture for virtualized naval shipboard computing systems based on open architecture. Our proposed architecture integrates individual computing resources into one single integrated hardware pool so that the OS and applications are encapsulated as a VM. We consider the issue of varying needs of all applications in a naval ship that have different purposes, priorities and requirements. We also present parallel VM migration algorithm that improves the process time of resource reallocation of given architecture. The evaluation results with the prototype system show that our algorithm performs better than conventional resource reallocation algorithm in process time.

과거와 다르게 최근의 병원들은 정보화로 인해서 상당한 양의 의료 데이터가 저장되어 있어서 이의 효과적인 이용에 관심을 가지고 있다. 그러나 기존 통합병원정보시스템(Integrated Hospital Information System)은 아직까지 일반관리와 원무관리 중에서 벗어나지 못하고 있다. 품질 좋은 의료 서비스를 제공하기 위해서 환자 중심의 진료 및 진료지원, 임상연구 등을 종합적으로 지원하기 위한 데이터 웨어하우스(Data Warehouse)의 필요성이 대두되기 시작했다. 이에 본 연구는 병원 전체 차원에서 데이터 웨어하우스의 아키텍쳐를 설계하고 개발하는 데 주안점을 두었다. 특히, 임상 데이터 웨어하우스(Clinical Data Warehouse)에 초점을 두었으며 이에 대한 프로토타입은 J 병원에 적용되어서 개발되었다.
