OLAP은 데이터 마이닝, 데이터 비주얼라이제이션, 데이터웨어 하우징 등의 최신 의사결정지원 기술과 마찬가지로 전반적인 비즈니스 인텔리전스 프레임웍의 핵심 컴포넌트중 하나이다. 하지만 시스템 환경이 복잡해지고, 사용자들의 요구가 다양해짐에 따라 하나의 제품군이 모든 사용자 업무를 지원한다는 것은 무리이다. 이를 위해 각 제품들은 상호 통합 및 연계를 그 해결책으로 제시하고 있다.

As a part of NERI:;, Truck Shipment Safety Information is divided into Optimal Route Guidance system and Emergency Response system. This study which is for developing of Truck Shipment Incident Emergency Response System intends to prevent or early response damage caused by incidents through realtime monitoring about the position and the state of Hazard material transport truck. For this, we divide it into three scenarios; realtime monitoring, management of incidents, information provision to related organizations and present functional requirements and architecture coming with each scenario. As a result of the first step among total three steps, it would able to not only realtime management of trucks but also guide for auto-enforcement or management about illegal act like dumping scrapped material. It is now under examination about position of detection and technology of communication to application. From now on, it is expect to test in the range of Metropolitan after selecting appropriate technology.

PMIPv6(Proxy Mobile IPv6) is a network-based IP mobility management protocol, which can control the mobility without depending on the type of access system or the capability of mobile node. Combining it with SIP mobility, it can establish the route optimization effectively and ensure the terminal mobility and the session mobility. There are many literatures on PMIPv6-SIP in mobility management, but efficient performance analysis and mathematical modeling has not been standardized. For this, a new PMIPv6-SIP architecture is proposed to compare with Pure-SIP in terms of the handover delay and packet loss.

다양한 플랫폼 상에서 응용 시스템에 대한 개발, 배포, 운영의 고생산성과 고품질을 얻기 위해서는 소프트웨어 구성 요소들의 체계적인 재사용 접근과 자동화된 도구의 지원이 요구된다. 함수나 클래스 라이브러리에서 설계 패턴과 프레임워크, 그리고 최근의 상업적인 비즈니스 컴포넌트에 이르기까지 여러 재사용 방법이 제시되었으나 기대만큼의 확실한 효과를 얻을 수 없었다. 설계 패턴은 설계 경험에 대한 캡슐화된 빌딩 블록으로 개발 응용의 표준화된 아키텍쳐 제공을 통해 응용 도메인의 한정성과 클래스 수준의 재상용의 복잡성을 극복할 수 있다. 응용 개발의 표준 아키텍쳐로서의 웹을 통한 재사용 요소들의 공유는 여러 개발자들에 의한 다양한 도메인 요소로서의 전개와 동적이며 실시간적인 라이브러리 관리가 가능하다. 본 논문에서는 웹 환경 하에서 자동화된 설계 패턴 재사용 환경 구축을 목적으로 한다. 그러므로 For Reuse 관점에서 서버 상에 각 도메인별 패턴 라이브러리를 구축하며 With Reuse 관점에서 패턴 검색, 이해, 획들 그리고 재구조화를 통한 응용으로의 재사용 지원기를 구축한다. 본 시스템은 패턴의 공유에 의한 유사 도메인 응용의 표준화를 유도하고 사용자의 패턴 재정의에 의한 자생적을 확장 가능한 패턴 라이브러리 제공이 가능하다. 또한 이를 위해 도메인 분석을 통한 패턴의 행위와 의도를 기준으로 설계 패턴들을 분류, 카탈로깅하여 재사용 라이브러리를 제시한다.

Public service provision through internet is one of major parts for e-government implementation. It is essential to link the internal administrative network with internet to provide the services through internet and to support kiosks through internet, which should result in critical issues for security. A relay server, as a front server for the public service processing system and a web server, a control server for kiosks, are placed between the public service processing system and kiosks to solve those security issues. It is the way to solve security issues through protecting direct communication between the public service processing system and a web server and authenticating a relay server and a web server through authentication process. In the implementation of the system this paper provide a design for an architecture model of the public service processing system through internet, which are aiming to develop high level of the quality system effectively, to reduce the risk of initial stage of development, and to reduce the incurring cost due to reworks.

This paper presents the design and the implementation of CRESTIVE-DX, a concolic testing tool that distribute the concolic testing process over the embedded target system and the host system for efficient test generation of a target embedded program. CRESTIVE-DX conducts the execution of a target program on the target embedded system to consider possible machine-dependent behaviors of a target program execution, and conducts machine-independent parts, such as search-strategy heuristics, constraint solving, on host systems with high-speed computation unit, and coordinates their concurrent executions. CRESTIVE-DX is implemented by extending an existing concolic testing tool for C programs CREST. We conducted experiments with a test bed that consists of an embedded target system in the Arm Cortex A54 architecture and host systems in the x86-64 architecture. The results of experiments with Unix utility programs Grep, Busybox Awk, and Busybox Ed show that test input generation of CRESTIVE-DX is 1.59 to 2.64 times faster than that of CREST.

In our country security industry biz model analysis methodology fragmentary theory exists, but it is hard to find a comprehensive analysis methodology. Biz model analysis IT companies the external factors and internal factors to integrate the information gathered about the comprehensive analysis of the development of an information system are required. Information support system early in the software architecture of the system design decisions early decision as the design, development, testing, maintenance, has a lasting impact on the project as a guideline in the development of a framework of design abstraction. BMO evaluation support information systems architecture designs system purposes. The mission must support the execution. Information system stakeholders to determine the mission and the environment. All information systems architecture shall have architecture. Technology architecture should be documented with each other can be used. Determine the architecture based architecture descriptions are presented.

As today's Information Technology (IT) becomes more global and specialized the importance of Information Technology Architecture (ITA). Based on the case study of e-commerce, this paper presents a systematic approach to Information Strategy Planning (ISP) with ITA. To implementation of strategic approach, ITA is developed to establish e-commerce projects. It is believed that the Chief Information Officer (CIO) will be more receptive to results that include ISP and ITA are combined simultaneously.
