본 논문에서 제안하는 움직임 모드 알고리즘은 움직임 추정 이전에 움직임 모드를 결정하여 기존의 모든 블록에 대해 움직임 추정하는 방식을 선택된 모드에 대해서만 움직임 추정을 진행한다. 다른 모드 결정 방법과 비교했을 때 PSNR은 비슷한 수준이었고 비트율은 적은 것을 실험을 통해 확인 하였다. 반면 다양한 영상의 인코딩 시간을 측정하여 다른 방법보다 평균 30% 시간을 줄일 수 있다.

디자인 패턴은 소프트웨어 설계 시 반복적으로 발생하는 문제를 해결하기 위한 방법을 기술한다. 특히, 객체지향 기술을 기반으로 하는 컴포넌트 설계 시 디자인 패턴을 활용함으로써 특정 설계 문제에 대한 해결책을 재사용할 수 있다. 좋은 객체 지향 설계는 재사용성, 확장성 및 유지보수성을 제공하는 것이며, 디자인 패턴은 좋은 설계에 필요한 구성 요소들의 관계 구조를 제시한다. 본 논문은 객체지향 기반의 컴포넌트 프레임워크 설계 시 프레임워크의 확장성과 구현 컴포넌트의 재사용성을 늘리기 위한 방안으로 디자인 패턴의 활용법을 제시한다. 특히, 알고리즘 재사용의 구조를 제시하는 전략 패턴과 처리 절차 재사용의 구조를 제시하는 템플릿 메서드 패턴의 구조를 비교하고, 분산 통신 컴포넌트 설계 시 전략 패턴의 적용 사례를 보여준다.

The increasing importance of software has highlighted the need for the proper application of software ILS. On the other hand, the development of ILS has been somewhat limited to the area of hardware development. Therefore, this study examined the potential difficulties in applying software ILS to practical uses, and analyzed the drawbacks by reporting several domestic or foreign regulation cases. In addition, the differences between hardware and software ILS were examined by considering their characteristics of maintenance. Eventually, by establishing the proper range, this study proposes a development plan that is suitable for domestic weapon systems. The proposed research is expected to be helpful for offering specific plans for designing software ILS.

This paper describes the design of model-based fault diagnosis software to apply to the propulsion system in tracked amphibious assault vehicle which consists of an engine, a transmission, a cooling system, and two waterjets. This software includes specific functions to detect the failures regarding sensor malfunctions, mechanical malfunctions, control errors, and communication errors. This software generates the proper malfunction codes which are classified as the warning and caution. In order to validate the fault diagnosis software, the manual and automatic test are performed using the test program with 32 test cases. Test results show that the designed fault diagnosis software is reliable and effective for applying to the propulsion system.

Hardware, software, networking to Digital Contents. Most of the Small and medium IT Enterprise strategy shift of R & D system. In 2001, IT Small and medium size manufacture occupied 3.8% of Gross Domestic Product. IT industry R&D Program and Excellent Information Technology R&D Program support rate $54{\sim}60%$ of computer, software and contents for Information Technology R&D, when the Technology of R&D input to market need to development for about 3 years. Most of the Small and medium IT Enterprise strategy priority find out from computer, software and contents.

The IISS(Integrated Interface Storage System) software performs the function of transmitting tactical domain messages of Combat Management System for interface analysis of Naval Combat System. The source code is relatively large because the IISS software handles most messages. The modifications of source code of the IISS software occur frequently due to changes in interconnected equipment and messages. Therefore, additional effort and cost are required during the development process. In this paper, we studied standardization of the IISS software to improve reusability. Through the feature model, the components of the IISS software were divided by function and modification elements were separated. And the structure of the IISS software was improved by applying design patterns. As a result, it was possible to minimize modifications of the IISS software by changes in interconnected equipment and messages and a reduction in development costs could be expected.

Most manufacturing enterprises create CAD data as a result of the product/part design process; however, the CAD data is being utilized only for production activities. Besides the processes directly related to manufacturing such as design and production, the CAD data is an important resource that can be used in variety of services (e.g., catalog production and production manuals) for manufacturing enterprises. This study proposes a software platform that can support a wide range of services for manufacturing companies in an efficient and productive way. The software platform was designed based on the functions identified by requirement analysis. The platform consists of four layers: data model layer to manage relevant data; library layer and common function layer to configure services; and application layer to install and run the software. Finally, this study evaluates the validity of the proposed platform architecture by applying it to the digital catalog system.

군용장비를 시험하고 훈련하는데 사용되는 모의 소프트웨어는 체계마다, 장비마다 새로이 개발된다. 따라서 모의 소프트웨어를 설계, 개발하는 시간이 길어지고 관리 비용도 늘어난다. 이러한 비용을 줄이고자 본 논문에서는 모의 소프트웨어 개발을 위한 어플리케이션 프레임워크를 제안한다. 먼저 모의 소프트웨어가 공통으로 설계될 수 있는 부분을 추출하고, 이를 어플리케이션 프레임워크에서 미리 만들어진 형태로 제공한다. 여기서 추출한 공통 설계 구조는 다른 장비와의 연동을 위해 메시지를 주고 받는 인터페이스를 구현하는 부분이다. 이 인터페이스를 일관성 있게 개발하기 위하여 코드 생성 프로그램의 형태로 어플리케이션 프레임워크를 설계하였다. 설계된 어플리케이션 프레임워크는 일관된 개발 환경을 제공하여 모의 소프트웨어 개발 시, 설계 및 개발 시간을 줄이고 관리비용을 줄일 것으로 기대된다.

The information technology, such as computer, telecommunication, semi- conductor and software technology, is very crucial to enhance the overall level of industrial technology. The workability of linear programming to decide the R&D investment of information technology has been tested in this paper. The case study of Korea during the year 1995 - 2004 suggests that we should enlarge the total investment volume especially on the software technology.
