최근 전산 환경은 통합되는 개방형 시스템으로 변모하고 있고 JFC(Java Foundation Classess : Swing)는 분산 네트웍 환경에서 매우 적합한 환경으로 주목 받고있다. DB와 application에서 부수적인 문제점들이 발견되고, 서로 다른 platform을 기반으로 한 client들과의 연동을 위해서, platform에 따른 application이 개발되어야 했다. 이런 환경에서 개발자가 프로그램 변경이 발생할 때 연결관계에 따라 템플리트에 의해 개발된 부분을 코드로 변경해 주는 도구가 필요하게 되었다. 이를 위해 JFC기반의 통합 Middleware의 선정이 필요하게 되었다. 따라서, 본 논문에서는 JFC기반의 통합 관리하는 통합 객체 관리 모델을 설계한다. 이것은 특히 컴포넌트 재구성을 위한 것이고, 목적은 기존의 시스템을 재사용하고 현존하는 컴포넌트를 재구성하여 최소한의 코드 수정을 통하여 시스템을 구동할 수 있게 함으로써 소프트웨어의 경제성을 높이는 것이 본 논문의 목적이다.

This paper describes our experience to design and implementation of a collaborative system framework that allows to develop certain collaborative applications such as 3D animation, computer game, and industrial design. The collaborative system enables users, who located in geographically long distance, to do collaborative work in a single virtual space. The proposed system basically consists of client and server system. The goal of proposed system is to support scalability, portability, and platform independent. In order to achieve these, the server is implemented in Java platform and is adopted to the hybrid architecture which takes the advantages both in centralized and decentralized collaborative system. We construct the server base on its functional characteristics so called User Manager Server (UMS), Session Manager Server (SMS), and Information Server (IS), The UMS manages the users who are taking part in the collaborative operations. The SMS supports the conferencing in the proposed system. The IS provides the connection methods among the UMSs. For user's convenience, we implement the client using Visual C++ in Windows. We also expend the functions of 3D Studio Max to distributed environment by means of the plug-in module, and facilitate the chatting and white board functions as well.

With the recent development of the ubiquitous computing technology, there are increasing interest and research in technologies such as sensors and RFID related to information recognition and location positioning in various ubiquitous fields. Especially, a standard specification was required for compatibility and interoperability in various RTLS(Real-Time Locating Systems) according to the development of RTLS to provide location and status information of moving objects using the RFID Tag. For these reasons, the ISO/IEC published the RTLS standard specification for compatibility and interoperability in RTLS. Therefore, in this paper, we designed and im plemented RTLS based on the spatial DSMS(Data Stream Management Stream) for efficiently managing and searching the incoming data stream of moving objects. The spatial DSMS is an extended system of STREAM(STanford stREam datA Manager) developed by Standford University to make various spatial operations possible. RTLS based on the spatial DSMS uses the SOAP(Simple Object Access Protocol) message between client and server for interoperability and translates client's SOAP message into CQL(Continuous Query Language) of the spatial DSMS. Finally, we proved the efficiency of RTLS based on the spatial DSMS by applying it for the staff location management service.

Recently Digital multimedia broadcasting (DMB) has been available as a commercial service. The users sometimes have difficulty in finding their preferred multimedia contents and need to spend a lot of searching time finding them. They are even very likely to miss their preferred contents while searching for them. In order to solve the problem, we need a method for recommendation users preferred only minimum information. We propose an algorithm and a system for recommending users' preferred contents using preference transition probability from user's usage history. The system includes four agents: a client manager agent, a monitoring agent, a learning agent, and a recommendation agent. The client manager agent interacts and coordinates with the other modules, the monitoring agent gathers usage data for analyzing the user's preference of the contents, the learning agent cleans the gathered usage data and modeling with state transition matrix over time, and the recommendation agent recommends the user's preferred contents by analyzing the cleaned usage data. In the recommendation agent, we developed the recommendation algorithm using a user's preference transition probability for the contents. The prototype of the proposed system is designed and implemented on the WIPI(Wireless Internet Platform for Interoperability). The experimental results show that the recommendation algorithm using a user's preference transition probability can provide better performances than a conventional method.

Purpose: The aim of this study was to analyze the tasks of managers who were working in the Customized Visiting Health Services (CVHS) and to prioritize analyzed tasks according to performance frequency, perceived importance, and difficulty. Methods: Job analysis method by Hartley (1999) was used for task analysis and performance frequency, perceived importance, and difficulty were used for prioritize as criteria. A total of 85 managers in the CVHS of public health centers nationwide were recruited through e-mail and mail survey. Using SPSS/WIN 15.0, descriptive statistics, such as frequency distribution, means, median, and standard deviation, were conducted to examine each subject's general characteristics, the frequency, importance, and difficulty of the tasks as well as to prioritize the each task. Results: The job description of the managers revealed 12 duties, 35 tasks, and 104 task elements. Of the 85 managers, 84.8% were classified as nurses, 40.5% were home health care specialists, and 32.9% were social workers. Their coretasks were management of client cases, budget management, and management of work performance and quality assurance. Conclusion: Considering the analyzed managers' tasks and core tasks, we need to examine each manager's role precisely and provide various educational programs for improving overall manager competence.

Since the mid-1990′s, researches on 3D GIS have been regarded as one of main issues both in the academic sites and commercial vendors; recently, some prototyped systems or the first versioned software systems of commercial basis are being reported and released. Unlike conventional 2D GIS, which consists in intelligent structured GIS or desktop GIS, every 3D GIS has its own distinguished features according to data structure-supporting capability, GIS-styled functionality, external database accessibility, interfacing extents with 2D GIS, 3D visualization/texture mapping ability, and so forth. In this study, technical aspects related to system development, SERI-Web3D GIS ver. 1.2, are explained. Main features in this revised 3D GIS can be summarized: 2-tier system model(client-server), VGFF(Virtual GIS File Format), internal GIS import, Feature manager(zoning, layering, visualization evironment), Scene manager(manage 3D geographic world), Scene editor, Spatial analyzer(Intersect, Buffering, Network analysis), VRML exporter. While, most other 3D GISes or cartographic mapping systems may be categorized into 3D visualization systems handling terrain height-field processing, 2D GIS extension modules, or 3D geometric feature generation system using orthophoto image: actually, these are eventually considered as several parts of "real 3D GIS". As well as these things, other components, especially web-based 3D GIS, are being implemented in this study: Surface/feature integration, Java/VRML linkage, Mesh/Grid problem, LOD(Level of Detail)/Tiling, Public access security problem, 3-tier architecture extension, Surface handling strategy for VRML.
