Software is developing toward having more large scale and many functions day by day. Also, user’s requirements level for software is being high, especially, requirements for software quality is being high continuously. Methods which can satisfy such User’s requirements is being studied in various viewpoint. First of all, study about quality evaluation system and methodology is energetically in progress in viewpoint to improve quality of software by feed-back software quality evaluation result to developers. In this paper, we define metrics according to a system and developed quality measurement tables according to internal characteristics system of quality characteristics, subcharacteritics, internal characteristics for reliability between quality characteristics of international standard, ISO/IEC 9126 about software quality. And we propose evaluation results about development products using internal characteristics.

Because a medical embedded software is the software that control the medical devices that are relevant to a human life, it requires high qualify level. It is requires to develop and apply the quality test module that suitable for the requirements to meet the high quality requirements of the medical embedded software. Also, it needs to develop the process that complement the quality defects of software by feedback of the test result. In this study, we developed test module and quality inspection table which can test medical embedded software and produce result based on ISO/IEC 12119.

The main objective of this paper is come up with methodology approach for FPGA-based system in verification and validation lifecycle regarding software reliability using system engineering approach. The steps of both reverse engineering and re-engineering are carried out to implement an FPGA-based of safety critical system in Nuclear Power Plant. The reverse engineering methodology is applied to elicit the requirements of the system as well as gain understanding of the current life cycle and V&V activities of FPGA based-system. The re-engineering method is carried out to get a new methodology approach of software reliability, particularly Software Reliability Growth Model. For measure the software reliability of a given FPGA-based system, the following steps are executed as; requirements definition and measurement, evaluation of candidate reliability model, and the validation of the selected system. As conclusion, a new methodology approach for software reliability measurement using software reliability growth model is developed.

As the area of software application is increased. the software is becoming larger and more complex. In addition, development of the high quality software within the limits of the budget is strongly demanded. Many methodologies, such as software process improvement, object-ori-ented development, requirement-engineering, and software metrics have been introduced in the software development process in order to attain such objectives. Among those techniques. Requirements-Engineering gives basic guideline to develop high quality software. In other word. in order to develop high quality software, requirements should be elicited, and described. And with proper reviews and management. the quality of requirements can be improved. In this paper, quantitative measurement method that is based on IEEE Std-830-1998 for the require-ment-specifications is proposed.

Development of human-system interfaces (HSI) supporting the interaction between human and automation-based systems, particularly safety-critical sociotechnial systems, entails a wide range of design and evaluation problems. To help HSI designers deal with these problems, many methodologies from traditional human-computer interaction, software engineering, and systems engineering have been applied; however, they have been proved inadequate to develop cognitively well engineered HSI. This paper takes a viewpoint that HSI development is itself a cognitive process consisting of various decision making and problem solving activities and then proposes a design requirements-driven process for developing HSI. High-level design problems and their corresponding design requirements for visual information display are explained to clarify the concept of design requirements. Lastly, conceptual design of software system to support the requirements-driven process and designers' knowledge management is described.

Nowadays, as the importance of SOA-based software is recognized, the market of SOA-based software is getting bigger. In response to this, the requirements about high reliability and quality SOA-based software is getting increased. In this research, we clearly suggested the evaluation method by giving a specific evaluation example to evaluate the quality of SOA-based software. It is expected to raise the objectivity and the utilization by inducing the quality improvement from this research.

All medical information system stakeholders and the environment exists. Medical information systems for development in these environments and non-functional requirements, functional requirements and quality goals are to be met. In order to achieve these goals in a variety of ways currently being made to develop information systems and various applications are emerging. However, the process of developing these health information systems meet the basic requirements and does not consider that from the point of view should not be separate. This study of the development of health information systems related to quality measurement indicators for the analysis software architectures, and medical information, information quality evaluation of service quality information associated indicators evaluation are offered. This way of associated indicators for the quality of the output sum and analyze the trends in software architecture u-Healthcare should be available for assessment. Quality score compared with pre-set goals for achievement and satisfaction levels of analysis further support the cause excerpt field use in analysis and improvement is possible.

The object of quality test for weapons system embedded software is support about implement of high quality system which coincided with requirements of weapons system embedded. There are some examples which developed quality evaluation methodology, evaluation method for general embedded software. But the concrete system for weapons system embedded software was not constructed yet. Recently, various weapons system embedded software were developed and used but they require the effort for the quality. In this paper, we developed the evaluation modules and the quality test tables which can evaluate based on ISO/IEC 12119 for weapons system embedded software evaluation.

It is possible to implement high quality system which coincided with embedded system purchaser's requirements by quality test. The concrete quality test system applicable within our country for embedded software was not constructed yet. Recently, various embedded systems are developed, but they have many problems such as recall by defect. In this paper, we developed evaluation modules and quality test fables which can implement duality test based on ISO/IEC 12119 for embedded software evaluation.

To design a software system many architecture styles have to be combined to construct the overall architecture of the system What to choose among various architecture styles or architectural approaches depends on the fact of what kind of functional or non-functional quality requirements the system should satisfy In this study, we define the method to choose suitable architectural approaches by the satisfaction level of system requirements that is evaluated through estimation about technical parts of architectural approaches, and verify the evaluation method by the case study that apply the evaluation method to choose architectural approaches for message system.
