This paper describes the quality attributes of an integrated simulation software for weapon systems named Advanced distributed simulation environment(AddSIM). AddSIM is developed as a key enabler for Defense Modeling & Simulation(M&S) systems which simulate battlefields and used for battle experiments, analyses, military exercises, training, etc. AddSIM shall provide a standard simulation framework of the next Defense M&S systems. Therefore AddSIM shall satisfy not only functional but also quality requirements such as availability, modifiability, performance, testability, usability, and others. AddSIM consists of operating softwares of hierarchical components including graphical user interface, simulation engines, and support services(natural environment model, math utility, etc.), and separated weapon system models executable on the operating softwares. The relation between software architectures and their quality attributes are summarized from previous works. And the AddSIM architecture and its achievements in the aspect of quality attributes are reviewed.

In this study, a framework for web-based information system in VDN environment for safety and health monitoring in subway stations is suggested. Since physical variables that describing safety and health need to be closely monitored in multiple locations in subway stations, concept of distributed monitoring network using wireless media needs to be implemented. Connecting remote wireless sensor network and device (LonWorks) networks to the IP network based on the concept of VDN can provide a powerful, integrated and distributed monitoring performance, making a web-based information system possible.

This paper presents the formal integration of process planning and shop floor control with Petri net formalism. Formal integration means that both planning and control problems can be modeled, interfaced, and transformed with the Petri net formalism. This integrated framework provides a systematic approach for rapidly developing a formal shop floor controller from process planning with respect to shop floor configuration.

본 논문에서는 유무선 통합 망에서 미디어 파일과 같은 자원들을 효율적으로 공유하기 위해, 이동 에이전트 기능을 사용하여 P2P 플랫폼을 설계하였다. 현재 대다수의 P2P 애플리케이션들은 유선망을 기반으로, 서로 다른 API를 사용하고 있어, 플랫폼에 종속적이며, 다양한 네트워크 환경과 디바이스 등을 포함하지 않는다. 이러한 문제점을 해결하기 위해 오픈 소스 프로젝트인 썬의 JXTA를 이용하여 전체 시스템을 설계하였으며, 기존의 JXTA 프로토콜의 문제점을 모바일 에이전트를 이용해 개선하고자 한다.

In this article are proposed a theory of the French syllable and a rule of French liaison within the dependency phonology framework. The treatment offered assumes that the notion of 'floating' or 'extrametrical' segment allows for a better description than competing alternatives based on truncation or insertion. This rule was based on the consequences of positing floating segments for the structure of lexical entries and underlying phonological representations. I have described the phenomenon of French liaison and shown that insights normally associated with metrical and 'autosegmental' accounts could naturally be integrated within the syllable structure.

A mobile computing environment has many difference in character from conventional communication over wired network. These include very presents distributed design system based the mobile agent for mobile computing environment. To integrate design resource, we presented ISA(Integration Service Agent, which allows a designer to build integrated application using distributed resources, and to collaborative by exchanging service. Also we propose ICM(XML based Intelligent Connection Manger) using mobile agent. And suggested new intelligent data and process transfer architecture using ICM to implement an agent based design system in mobile environment.

In this paper, Internet based ship technical information management system has been developed as a means to accumulate, manage, share and utilize various distributed applications and information used for ship design and building. The information managed in the system are data from whole life cycle including concept design, basic design, detailed design, construction, operation and maintenance. In addition, using the developed system, integrated system framework is also proposed to integrate applications and database in concurrent engineering environment.

The purpose of this paper is to develop a modeling framework for analyzing the effect of price on the PCS (Personal Commununications Service) demand. To achieve this aim, a nonlinear regression model was derived to capture the income effect on the PCS demand and then was combined into an integrated Bass diffusion model. The model was then applied to the emerging PCS market in Korea and the market demands up to the year 2006 were estimated. The results were reviewed and evaluated in various aspects. Finally, the possibilities of model enhancement and model extensions were explored.

The analysis on the relationships among SPI models and restructuring SPI models according to a common framework makes it possible to compare and integrate the numerous research results about the models. It also makes it possible to assess objectively and accurately the results and benefits of evaluating an organization which has been evaluated according to a partial SPI model according to a new and integrated SPI model.

본 논문에서는 기존의 유선망을 기반으로 하는 P2P 시스템에 썬의 JXTA와 JXME를 이용하여 모바일 기능을 추가하였으며, 유무선 통합 망에서 미디어 파일과 같은 자원들을 효율적으로 공유하도록 설계하였다 현재 대다수의 P2P 애플리케이션들은 유선망을 기반으로, 서로 다른 API를 사용하고 있어, 플랫폼에 종속적이며, 다양한 네트워크 환경과 디바이스 등을 포항하지 않는다. 이러한 문제점을 오픈 소스 프로젝트인 썬의 JXTA를 이용하여 전체 시스템을 설계하였으며, JXTA 프로토콜을 이용하여, 피어의 상태 정보를 모니터링하여, 원격 피어의 상태에 따라 동일한 파일을 설러 피어들로부터 전송 받을 수 있도록 한다.
