Even though many approaches for reuse have been introduced, software engineers are still hesitating to reuse existing software components. Among various reasons for the phenomena, the most significant one is that existing approaches failed to give substantial benefit for the reduction of developers' effort in reusing software assets. To solve this problem, we introduce a custom reuse model utilizing diverse aspects of components specified by RAS and services oriented architecture. We also carried out a case study to demonstrate its feasibility and evaluated it by comparing it to an existing code-based software reuse process. The proposed reuse model helps in the reduction of effort in reusing existing components by decreasing the time for searching and understanding them. Compared to other approaches such as product line engineering, our approach for software reuse using MPC does not require much initial work for implementing the reuse model in different projects. It is of interest to software engineers who are worried about heavy investment, which can cause the delay in their usual development work. Furthermore, the proposed reuse model is not mutually exclusive with other approaches for software reuse such as CBSD or product line engineering. It can accelerate the benefits gained from them.

In this paper, a software-based real-time GPS L1 receiver is proposed for the block correlation techniques. Recently various navigation satellite navigation receivers in the environment for the development of more efficient software-based real-time receiver need to be developed. It is composed of components such as signal supplier, signal acquisition, signal tracking, navigation data processing, and navigation solution. They are designed and implemented as component based software for enhancing reusability and modifiability for user to have more flexibility during development of receiver. This paper will describe design, implementation, and verification of the developed realtime software GNSS receiver.

In accordance with the development of recent computer technology, the dependency of railway signaling system on the computer software is being increased further, and accordingly, the testing for the safety and reliability of railway signaling system software became more important This thesis suggested automated an analysis tool for S/W metrics on this railway signaling system, and presented its result of implementation. The analysis items in the implemented tool had referred to the international standards in relation to the software for railway system, such as IEC61508 and IEC 62279. This automated analysis tool for railway signaling system can be utilized at the assessment stage for railway signaling system software also, and it is anticipated that it can be utilized usefully at the software development stage also.

We need to measure the quality of each module to assess software quality. Especially, in industry, it is important to measure quality of modules quantitatively in order to improve bad modules and reuse good modules. In this paper, we define moduleness as characteristic that modules should be possessed and propose a method to measure software moduleness quantitatively. A case study conducted in this paper shows the usefulness of the method by measuring and evaluating moduleness of modules based on open source software developed by C, C++ and Java languages.

소프트웨어 프로세스는 소프트웨어와 이에 관련된 산출물을 개발, 유지하기 위해 사용하는 활동, 방법, 절차의 집합이라고 할 수 있다. 프로세스를 기반으로 작업하는 조직은 필요한 프로세스들을 파악하고, 각 프로세스들을 구현하기 위해, 담당자를 할당하고, 수행 활동을 정의한 후, 이를 기반으로 작업을 수행한다. 이 때 보다 효과적으로 작업하기 위해 적절한 도구들을 활용하기도 한다. 소프트웨어 개발에서 도구의 활용은 이미 그 효과가 검증되었고, 많은 상업용 제품들이 개발되어 현장에서 사용되고 있다. 이러한 도구들 중에는 독자적으로 하나의 프로세스를 지원하는 독립형(Standard Alone) 도구들과 여러 프로세스를 지원하는 통합형 도구들이 있다. 통합형 도구들은 여러 프로세스를 연결하고 통합 관리하기 때문에 효과가 크지만, 주로 가격이 비싼 상업용 제품들이고, 대규모 프로젝트에 적합한 복잡한 기능이 많아 소규모 조직이 채택하기에는 어려운 경향이 있다. 독립형 도구들은 통합형 도구보다 상대적으로 기능이 복잡하지 않고, 공개 소프트웨어로도 제공되고 있기 때문에 소규모 조직들도 사용해 왔지만 통합형 도구와 같은 효과를 내기는 쉽지 않았다. 본 논문에서는 이클립스 플랫폼 기반에 독립형으로 존재하는 플러그인들을 통합하여, 여러 프로세스를 지원하는 이클립스 플러그인 모델을 개발하고, 그 효과를 살펴보았다.

Due to the rapid development of open source based Cloud management platforms such as OpenStack, many and various individuals and institutions are trying to construct Cloud computing systems based on open source software projects. It is essential, for those who install, administrate or operate a Cloud, to validate the integrity of the constructed Cloud system. This paper, therefore, proposes the design of a testing tool for validating the integrity of a constructed OpenStack-based Cloud system. Especially, the proposed testing tool utilizes the Tempest project which is an open source project that consists of OpenStack test cases. The proposed testing tool is expected to help developing Cloud technology and Cloud users.

In a software development process, it is necessary to have a method which verifies and satisfies users' requirements in their point of view. This allows the system developer to design a high qualify software system and have it developed and used in an effective way since users' requirements have well been shown through it. In this paper, we propose the RV-UI model system that can verify users' requirements a step ahead of system implementation step. This RV-UI model system has standardized user interface which is in practical use into functional model for each process and it is designed to satisfy users' requirements and manage configuration of them through the interface which has the Kano model.
