Software development of large scale program such as Operating System or University Total Information System is lengthy and costly process. In order to reduce cost, time and risk, there is currentry general acceptance of the need for Software Reuse System during the whole development cycles. In this paper, (from a practical point of view), the problem of existing reuse system methodology is analyzed and an implement method of software reuse system is presented. Also using this method Application Program Reuse System(APRS) which supports all phase of software life cycles is designed and implemented. This application program reuse system which is based on common language is considerably shown to reduce communication Error of requirement specification between systems analyst and end-user.

Software architecture is the blueprint for a software system and should provide consistent guidelines for design, implementation, and maintenance throughout the entire lifecycle of the system. Components, interactions between the components, well-formed structure, reasons, and various perspectives reflecting various stakeholders' concerns changing through the phases of software lifecycle are the key elements of software architecture. The architect identifies and engages the stakeholders, understands and captures stakeholder's concerns including those regarding life cycle, and lets the concerns reflected in the architecture. To do so, architect should take into consideration various contextual elements regarding the system too. We make an extended list of the elements, especially those of business application software architecture, that the architect should take into consideration and construct a model of the relationships between the elements.

웹의 짧은 역사에 비하여 웹 관련 기술이 급속히 발전하고 있다. 이것에 비하면 웹 어플리케이션의 품질 개선 속도는 이에 따르지 못하고 있다. 따라서 웹 시스템 개발에 대한 효율적인 개발 방법이 필요하다. 본 논문은 웹 시스템을 개발하는데 필요한 항목들을 기술하였다. ISO/IEC 12207표준에 근거하여, 웹을 기반으로 하는 소프트웨어 개발 모형을 분석 및 설계 단계를 중심으로 제시하였다. 컨텐츠를 웹 어플리케이션에 반영하기 위하여 프로세스와 엔터티 정의방법을 기술하였다. 본 모형을 사용한 KCC 정보통신(주) Web-RoadMap 방법론을 공공 프로젝트에 적용하였다. 적용결과 효율적인 웹 어플리케이션의 분석 및 설계의 한 모형임을 입증하였다.

It is inevitable to control the systematic failure to obtain the software safety integrity of embedded software installed in rolling stock. Because it is not possible to assess systematic failure integrity by quantitative methods, SILs are used to group documentation, methods, tools and techniques throughout software development lifecycle which, when used effectively, are considered to provide an appropriate level of confidence in the realization of a system to a stated integrity level. Normally, safety approval process is through generic product, generic application and specification application for. For safety approval on generic application of software based system, it is required to apply the certified software processes from the planning stage for the assigned SIL. As such, we will develop project specific application with high safety integrity within time limit of contractual delivery schedule through software assessment to the modified area with the re-use of certified software module and documentation. At this point, Hyundai Rotem has developed software processes applicable to support SIL 4 based on EN50128 which was assessed and certified by TUV SUD. This paper introduces the Hyundai Rotem's detailed approach and prospective action to achieve software safety integrity level.

본 논문에서는 스마트 센서 응용 소프트웨어를 테스팅하기 위한 효율적인 방법인 가상 센서 시스템을 제안한다. 센서 응용 소프트웨어를 테스트하는 보편적인 방법은 테스트 보드에 센서를 직접 연결시켜 테스팅 환경의 센서 측정값으로 응용소프트웨어를 테스팅 하는 것이다. 센서 측정값을 입력으로 센서 응용 소프트웨어를 테스팅함으로 발생하는 문제는 테스트 데이터가 제한적이라는 것이다. 즉, 테스트 데이터가 센서로부터 생성되기 때문에 소프트웨어 테스터가 테스트 데이터를 조절하지 못하는 문제가 있다. 이러한 문제를 해결하기 위해 가상센서 시스템을 제안한다. 가상 센서 시스템은 소프트웨어 테스터가 센서의 측정값을 조절할 수 있게 한다. 가상 센서 시스템에서 센서 선택, 센서 특성화, 출력 패턴 정의의 세 단계를 통해 가상 센서를 정의한다. 가상 센서 시스템을 통해 조절 가능한 센서 측정값을 사용함으로써 센서 응용 소프트웨어에 대한 효율적인 테스트가 가능하다. 본 연구의 유용성을 보이기 위해 가상 센서 시스템을 안드로이드 앱의 센서 프로그램에 적용해 보고 실험 결과를 보인다.

Currently there are numerous papers in which many new kinds of customizing stereotypes by UML extension mechanism for different application environments such as real-time system, Geographic Information System (GIS) and so on are proposed. However , these stereotypes that represent different type model elements such as class, association, generalization and so on have not yet been seen in one of the most popular visual modeling tool for software development, Rational Rose. Therefore, in this paper, a design of extended iconic stereotype for GNSS application in the UML class diagram and its implementation as a tool of StereotypeCreator for Rational Rose will be presented.

The application of software engineering is not common in the development of astronomical observation system. While there were component-wise developments in the past, large-scale comprehensive system developments are more common in these days. In this study, current methodologies of development are reviewed to select a proper one for the development of astronomical observation system and the result of the application is presented. As the subject of this study, a project of operation software development for an astronomical observation system which runs on the ground is selected. And the output management technique based on Component Based Development which is one of the relatively recent methodologies has been applied. Since the nature of the system requires lots of arithmetic algorithms and it has great impact on the overall performance of the entire system, a prototype model is developed to verify major functions and performance. Consequently, it was possible to verify the compliance with the product requirements through the requirement tracing table and also it was possible to keep to the schedule. Besides, it was suggested that a few improvements could be possible based on the experience of the application of conventional output management technique. This study is the first application of the software development methodology in the domestic astronomical observation system area. The process and results of this study would contribute to the investigation for a more appropriate methodology in the area of similar system development.

This paper presents a survey of software reliability modeling and it's application to pre-built software system combined with hardware such as numerical controller based on personal computer systems. Many a systems in these days are much more becoming software intensive and many software intensive systems are safety critical. For this reason, the technique well developed to measure of software reliability is very important for whom to assess such a system. This paper provides a brief idea of method to evaluate such a system's reliability based on hardware performance.
