The harness design process consists of repetitious routines to decide the wire configuration in its interior. A slight change in one of the wire's configuration will require a total reconfiguration of the entire wire system. Therefore, the harness design is extremely time consuming and is vulnerable to human errors by an engineer. Based on both electrical and mechanical area, Wiring Harness system is in complicated area. Existing systems are, therefore, not exactly suitable for practical use. This paper presents a novel framework for ameliorating existing system's defects. In this paper, Visio and Visual Basic was interfaced to process wire bundle information and wire bundle location to alleviate problems mentioned beforehand concerning harness design; at the same time developing the automation of the entire design process based on the feature based design method, optional print, and management of documents for reuse.

설계 문제의 추상화와 특정 영역의 일반적인 해결에 대한 정보 표현 및 구성요소 상호 간의 관련성을 효과적으로 나타내는 설계 패턴과 공통 도메인 응용 구축에서 자동화된 아키텍쳐를 생성하는 프레임워크의 사용은 WWW상에서 활용으로 더욱 가치를 높이고 있다. 또한 각 정보가 연관성에 따라 상호 연결되어 있어서 비순차적인 접근을 통해 데이터의 종류에 관계없이 저장, 관리가 편리한 하이퍼미디어 응용이 크게 활용되고 있다. 따라서 본 논문에서는 하이퍼미디어 응용 구축에 적용될 수 있는 패턴들을 식별하고 응용을 구성하는 객체와 이들 간의 관련성을 네비게이션이 가능한 노드와 링크로의 재구조화를 지원하기 위한 자사용 요소로서 설계 패턴을 제공하는 프레임워크를 제시함으로써 프레임 워크 및 생성 응용의 아키택쳐에서 패턴 재사용을 통한 생산성을 향상하고자 한다.

In this letter, we propose an overlaid hybrid division duplex (HDD) concept for cellular systems which divides a cell into inner and outer regions and utilizes the merits of both time division duplex (TDD) and frequency division duplex (FDD). The proposed system can take advantage of both TDD and FDD without handover between two duplex schemes. Moreover, it is shown that the proposed HDD system outperforms the conventional TDD or FDD system with mobile relay stations when the synchronization issue is considered in orthogonal frequency division multiple access systems. Thus, the proposed overlaid HDD can be considered as a new framework for future cellular systems.

Service-Oriented Architecture (SOA) is a new trend for the design of application architecture to enhance the degree of share and reuse with the concept of service. It comes from the current situation where the business environments are changing rapidly and therefore competitions are getting bitter. To cope with such business challenges, business (and/or applications) architecture needs considerably flexibility and reusability, and that's why SOA is accepted as one of the most effective framework for the business applications in these days. In this paper we propose an analysis and design methodology for the applications of SOA. To implement the proposed methodology, the service ontology needs to be defined first, and the tasks such as service profiling, workflow design and service orchestration need to be followed. To validate the expected effects on flexibility and reusability, the proposed methodology was compared with CBD (Component Based Development).

Recently, OOM(Object-Oriented Method) access method which begins to apply to software development is emphasizing development cost and time reduction through independent software reuse. But because of planning to the exclusion of the lack of knowledge and expansion or performance for development technology many problems are coming out. Therefore, this thesis suggests Effective Object-Oriented Modeling methods considering the plan for higher productivity enhancement of software in the software development life cycle. Effective Object-Oriented Modeling method includes, methods, Use Case modeling methods, Analysis Modeling methods, Design Modeling methods and others.

The difficulty of "information sharing", "information reusing" issues happening in Wireless Sensor Network is due to the heterogeneity of the application environment, data processing, communication protocol etc. Based on the introduction of the Ontology theory, though analyzing the sensor characteristic a general type of sensor ontology contains the definition of concept, frame structure and OWL design was proposed from the standpoint of sensor observation. The paper expounded a system framework of the domain ontology through the expansion of knowledge base on the general sensor could achieve the information sharing and reuse by semantic communication between the general sensor ontology and user. The research of this method would bring new idea to the semantic sensor network construction.

최근 국방 소프트웨어 분야에서는 모델링 및 시뮬레이션 기술이 각광받으면서 무기체계 개발을 위한 시뮬레이션 소프트웨어 개발 사업을 늘리고 있다. 특히, 시뮬레이션 요소의 재사용성 및 신뢰성 확보를 위한 개발 프레임워크 제공이 핵심기술로 떠오르면서, 시뮬레이션을 위한 공통 서비스를 제공하는 M&S 프레임워크가 개발되었다. 하지만 고객의 요구사항이 프레임워크의 기능 변경을 요구하는 경우 프레임워크가 적용된 모든 시뮬레이션 요소의 수정이 불가피하며, 추가 구성요소의 상호작용을 위한 인터페이스 재설계가 요구된다. 본 논문은 이러한 문제점을 해결하기 위해서 프레임워크의 요소를 DLL로 구현하여 기능 구성을 용이하게 하고, 구성요소 간 상호작용을 위해 데이터 기반 Publish-Subscribe 방식을 사용함으로써 프레임워크와 독립적으로 인터페이스를 설계할 수 있도록 한다. 특히, 프레임워크와 DLL 간 교환 메시지 객체에 대한 구조 설계를 제시한다.

효과적이고 체계적인 소프트웨어의 재사용을 위해서는 해당 도메인에 대한 공통된 자산을 먼저 개발해야 한다. 재사용을 위한 컴포넌트 집합은 복잡한 소프트웨어를 컴포넌트 단위의 구조로 분해하고 이를 다시 조립할 수 있도록 하여 생산성을 향상시키지만 광범위한 분석으로 인해 컴포넌트를 개발하는데 필요한 비용과 기간을 증가시키기도 한다. 이러한 문제점을 극복하기 위해 소프트웨어 제품 라인 공학을 적용하여 해당 도메인의 수요나 업무 수행을 만족하는 일련의 공통된 기능들을 이용하여 재사용할 단위인 핵심 자산을 구축하고 요구사항에 따라 목표 시스템을 단기간에 저비용으로 개발할 수 있다. 본 논문에서는 소프트웨어 제품 라인 공학을 통해 정의된 M&S프레임워크의 핵심 자산을 제시하고 이를 재사용해 기록장치 소프트웨어를 개발한 사례에 대하여 설명한다.

The tactical operation centers of future anti-aircraft missile systems provide the environment for the research on future air threats, tactical information, integrated battlefield environment creation and management, engagement control and command and control algorithms. To develop the key functional elements of integrated battlefield situation creation and processing and tactical operation automation processing operations, battery/battalion tactical operation control and reconfiguration design software are required. Therefore, the algorithm software of each function and the tactical operation display software and link software for interworking between equipment were developed as reconfigurable through a data-centric design. In this paper, a tactical operation display framework that can be reconfigured on the operation display of the tactical operations according to the battery/battalion is introduced. This tactical operation display framework was used to develop a common data model design for the reconfigurable structure of multi-role tactical operations with battery / battalion and mission views, and a display configuration tool that provides a tactical operation display framework for view development was also developed using the MVC pattern. If the tactical operation display framework is used, it will be possible to reuse the view design through the common base structure, and a view that can be reconfigured easily and quickly will also be developed.

The existing wireless LAN standard IEEE802.11b has many vulnerabilities from security point of view. The authentication mechanisms in IEEE802.11b have many vulnerabilities. As a result to complement the weak of IEEE802.11b authentication, the IEEE802.1x had been developed in the sense of providing strong user authentication with appropriate mechanism. But this mechanism does not perform AP authentication and there are also some weak points. And in confidentiality and message Integrity case, WEP is weak from key stream reuse attack, IV reuse attack and so on. For that reason, in this paper we propose secure wireless LAN system. Our system provides strong user authentication, confidentiality, and message integrity based on existing IEEE802.1x framework and TLS.
