The railroad geotechnical management system using ActiveX component is developed In this study. Component software is realized as a way that can offer good productivity and stability in software production through maximizing the reusability of software. Developed component software is very useful in saving to much time required for the development, increasing the re-usage rates, utilizing the component per function and substantially reducing the expenses for the tests and the error corrections. In addition, since it is easy to replace with other types of components that satisfy the needs of users, we can easily customize the applications.

A mobile agent system is the most common software paradigm for distributed applications. A software development model to develop efficiently for these systems is needed. Unified Modeling Language (UML) is a widely used software development model to develop a system for Visualizing, Specifying, Constructing, Documenting. However, UML can not describe in explicit way the necessary mobility of the mobile agent-based software systems. In this paper, the interaction diagrams of UML (sequence diagrams and communication diagrams) are extended and used to express the mobility of the mobile agents in three ways. For a case study, we applied the extended diagrams to a distributed file searching using mobile agents, and showed these diagrams can describe the mobility very well.

In this paper, we describe a development of ultrasonic nondestructive evaluation software to analyze steam generator of nuclear power plant. The developed software includes classical analysis method such as A, B, C and D-scan images. And it can analyze the size and the location of internal cracks using 2D image. To do such, we obtain raw data from specimens of real pipeline of power plants, and get the crack points using LPF and differential method from obtained ultrasonic 1-dimensional data. The results of applications showed that the developed software provided accurate images of cracks on various specimens.

Automated medical claims processing and billing is a popular application domain of information technology. Managing medical related data is a tedious job for healthcare professionals, which distracts them from their main job of healthcare. The technology used in data management has a sound impact on the quality of healthcare data. Most of Information Technology (IT) organizations use conventional software development technology for the implementation of healthcare systems. The objective of this experimental study is to devise a mechanism for use of rule-based expert systems in medical related edits and compare it with the conventional software development technology. A sample of 100 medical edits is selected as a dataset to be tested for implementation using both technologies. Besides empirical analysis, paired t-test is also used to validate the statistical significance of the difference between the two techniques. The conventional software development technology took 254.5 working hours, while rule-based technology took 81 hours to process these edits. Rule-based technology outperformed the conventional systems by increasing the confidence value to 95% and reliability measure to 0.462 (which is < 0.5) which is three times more efficient than conventional software development technology.

임베디드 시스템의 개발에서 저전력을 소모하는 소프트웨어 개발에 대한 요구가 증대하고 있다. 따라서 임베디드 소프트웨어 개발 과정에서 소모 전력에 대한 정량적인 예측을 가능하도록 하는 연구가 늘어나고 있는 추세이다. 기존의 소모 전력 분석은 소스 코드를 중심으로 이루어져왔으나 분석을 위한 노력 및 시간이 많이 요구된다는 단점으로 인하여, 소프트웨어 모델 기반의 소모 전력 분석 기법에 관심을 두는 추세이다. 본 논문은 UML 모델 기반의 임베디드 소프트웨어 모델링 과정에서 설계 모델을 이용한 소모 전력 분석에 주안점을 두었으며, 이를 위하여 OMG가 개발한 MARTE 프로파일을 확장하였다. 이러한 확장은 별도의 분석용 모델을 개발하지 않고, UML 다이어그램을 이용한 소모 전력 분석이 가능하도록 한다.

소프트웨어 제품의 품질을 평가하기 위한 방법으로써 품질 요소, 품질 항목 및 여러 가지 메트릭을 이용한 품질 모델들이 제시되어 왔다. 하지만, 소프트웨어의 품질을 보다 정확하게 평가하기 위해서는 각각의 특징에 맞는 특화된 모델이 필요하다. 본 논문에서는 소프트웨어 컴포넌트 개발에 있어서 개발이 진행중인 상태의 소프트웨어 내부 속성에 적절한 메트릭을 적용시킨 결과를 이용하여 개발 완료 후의 소프트웨어가 가지게 되는 외부 품질을 어떻게 추정하는지에 대한 외부 품질 추정 모델을 제시한다. 소프트웨어 품질을 측정하기 위한 메트릭을 적용한 결과로써 품질 자체를 측정하는데 한정하지 않고, ISO 9126에서 제시하는 소프트웨어의 내부 속성을 이용하여 소프트웨어 컴포넌트 개발의 각 산출물에 어떻게 적용시키는지에 대한 모델을 예제를 통하여 제시한다.

The size of software collection at any organization is increasing rapidly with the use of computer becomes popular for various applications. This trend points out the importance of proper 'catalog'or 'directory' for software collections, however, only 'title list' is found in practice. The problem of no proper directory with software collection would be more serious than the problem with book collection since browsing is not possible with softwares. Many of the expensive softwares will be a waste of money to purchase and to hold if no catalog about them is provided. In this paper the difficulties in applying AACR2 to software cataloging and the most important characteristic of computer software are discussed as well as presenting the necessity of localized information due to the requirement of a machine to be used, the difficulty using subject-based-call-number scheme, an expected way of searching software to design a location indicator, software qualifications to be cataloged, and so on. In addition, an analysis of randomly selected softwares after a cataloging practice is followed.

One of the most important prerequisites for a successful software process is the collaboration and software requirements negotiation of all stakeholders in the software development process. Remote users using computer networks can negotiate software requirements by computer supported system, and can share their informations. The goal of software requirements negotiation system is an integration of all win conditions and an agreement after resolution of conflicts. The existing systems need an exclusive system and must be dependent on specific platform and network. Users must have the knowledge of all stakeholder's status and use homogeneous collaborating applications. This paper presents the Web-based software requirements negotiation system for the purpose of resolution of the existing systems' problems. The Web-based software requirements negotiation system can be driven by WinWin Spiral model, and it is based on hybrid execution method. The proposed system is validated and tested on heterogeneous environments.

It is booming to use computer and information owing to the information society. As software applications have grown, so too has the importance of software quality. Therefore, software quality measurement and evaluation are necessary to satisfy the users who are using computers. The ISO/IEC 9126 defines six quality characteristics and twenty-one subcharacteristics including forty inter quality characteristics. We developed software measurement and evaluation technique using the check list in accordance with the ISO/IEC 9126 in design phase. We applied idea and concept of Total Quality Management in order to evaluate and measure the quality of software. Namely, it is the concept such as "you should do it right the first time." or "you have to build quality in the process." We executed the quantitative evaluation of software, also had shown the distinctive result in order that users and developers can find the errors easily. We evaluated the quality of academic softwares in order to verify developing technique at S college. As a result of the evaluation, this college has found it necessary to maintain the software as soon as possible because academic systems are not adequate for users at this present time.

AUTOSAR is a partnership of automotive manufacturers and suppliers working together to develop and establish a de-facto open industry standard for automotive software architectures. In the AUTOSAR architecture, the runtime environment is at in the heart of the AUTOSAR architecture to provides the infrastructure services that enable communication between software components and between software components and basic software components. The RTE generator is an automated generation tool for AUTOSAR specification based RTE according to the ECU configuration. It generates communication API function for the software components and the basic software components like OS and COM of the application. The availability and the accuracy of the RTE generator are important for the automobile software which is based on AUTOSAR architecture, this paper proposes an architectural design of the RTE generator for auto-generation of the AUTOSAR based RTE.
