모든 의료정보시스템에는 이해관계자와 환경이 존재한다. 의료정보시스템 개발 시에는 이 같은 환경에서 사용자의 기능적 요구사항과 비기능적 요구사항인 품질을 만족시켜야할 목표가 있다. 이 목표를 달성하기 위하여 현재 다양한 방법으로 정보시스템 개발이 이루어지고 있고 다양한 애플리케이션이 등장하고 있다. 그러나 이 같은 의료정보시스템 개발의 과정에서 기본적인 요구조건을 만족하고 있는지는 별도의 관점에서 고찰하지 않으면 안 된다. 본 연구는 유-헬스케어 서비스 소프트웨어아키텍쳐 품질확보를 위한 요구사항 분석방법을 제안한다. 의료정보시스템의 요구사항 분석을 통해 소프트웨어아키텍처 품질평가 사항과 의료정보서비스 품질평가 연계지표 평가방식을 제안했다. 이 방법은 연계성 팩터의 품질 합계치를 산출하고 그 추이를 분석하므로서 유-헬스케어 소프트웨어아키텍쳐에 대한 종합평가가 가능하게 한다. 품질평가는 요구사항 분석에서 도출된 목표와 비교하여 달성도를 분석하며 만족도 수준이 미진한 분야를 발췌하여 원인분석 및 개선작업에 활용이 가능하다.

We analyze the current quality management status for firms producing steel outfits of ships and develop an efficient QMS appropriate to Korean steel outfit industry. The firms recently obtained ISO 9000 certificates and are located in Pusan ${\cdot}$ Kyungnam district of Korea. The analysis is based on the audit results from ISO 9000 for seven steel outfit firms during last three years. We find out major requirements of ISO 9000 and investigate statistical relationship among major requirements, types of data, and groups of firms by using a statistical package, SAS. Recommendations regarding add-on requirements are suggested to install an efficient QMS in Korean steel outfit firms.

In this study, we first define user requirements to fulfill the reconnaissance and the search missions, by analyzing the system characteristics and operation environment. By investigating the design technology level, the development and procurement costs, the strong system design concepts and possible alternatives will be proposed. To analyze the system requirements, the Quality Function Deployment of the systems engineering approach will be implemented. The promising design alternatives that satisfy the user requirements are extracted by constructing the Morphological Matrix, then the best design concept will be obtained using the Pugh Concept Selection Matrix and the TOPSIS(Technique of Order Preference by Similarity to Ideal Solution).

International Organization for Standardization has recently published ISO 9001:2008 which is the basic requirements for a quality management system that an organization must fulfil to demonstrate its ability to consistently provide products that enhance customer satisfaction and meet applicable statutory and regulatory requirements. Not many empirical researches based on ISO 9001:2008 have been done up until now. In this article we outline transitional features for ISO 9000 quality management system (QMS) since its first publication in 1987. In order to effectively maintain ISO 9001:2008 QMS certification and continuously enhance quality management activities, we perform statistical analysis for the minor nonconformity data generated from follow-up audits for subcontractors of shipbuilding industry based on ISO 9001:2008 requirements. A Kruskal-Wallis test is used to show relationships between the minor nonconformity data and three classification criteria: the type of business, the size of business, and the number of follow-up audits.

MTTR and MTBSF are two representative quantitative maintainability and reliability requirements for railway systems. we deal with the redundancy allocation problem to satisfy the two requirements. The redundancy increases MTBSF and changes MTTR. Parallel redundancy and the exponential lifetime distribution of components are considered for the series systems. Mathematical model and example are presented for the redundancy optimization problem of minimizing the cost subjecting to MTTR and MTBSF requirements.

Requirements traceability is regarded as one of the important quality attributes in software requirements engineering field. If requirements traceability is guaranteed then we can trace the requirements' life throughout all the phases, from the customers' needs in the early stage of the project to requirements specification, deployment, and maintenance phase. This includes not only tracking the development artifacts that accompany the requirements, but also tracking backwards from the development artifacts to the initial customer requirements associated with them. In this paper, especially, we dealt with the traceability between functional requirements and non-functional requirements. Among many Information Retrieval (IR) techniques, we decided to utilize Latent Semantic Indexing (LSI) and Latent Dirichlet Allocation (LDA) in our research. Ultimately, we conducted an experiment on constructing traceability by using two techniques and analyzed the experiment results. And then we provided a comparative study between two IR techniques in constructing traceability between functional requirements and non-functional requirements.

Since 1997, JAB (The Japan Accreditation Board for Conformity Assessment) had started the activity of accreditation for the laboratory based on U.S. PL101-592: the Fastener Quality Act that was signed by President Bush on 1990. The number of accredit laboratories are 69 in Japan, 21 in Taiwan, 2 in Korea and 189 in U. S. A, as of 09/10/1998. The JAB accreditation encompasses the requirements of the ISO/IEC Guide 25, and the relevant requirements of ISO 9002. The purpose of ISO/IEC Guide 25, also had been harmonized as JIS Z 9325 'General requirements for the competence of calibration and testing laboratories 'mainly facilitates and promotes acceptance of calibration and test results between countries to avoid barriers to trade through as 'one stop testing'. The features and differences between Guide 25 and ISO 9000 will be clarify in this report.

User Requirements are analyzed and quantified by decision making models and system engineering methods to select alternative concepts which satisfy the various requirements. In this study, the design concepts for guided missile are derived using Quality Function Deployment(QFD) and Analytic Hierarchy Process(AHP). The design alternatives that satisfy the user requirements are extracted by QFD and Morphological Matrix, then the best design concept are obtained using AHP and Pugh concept Selection.

In this paper, the QFD(quality function deployment) technique is used to acquire the quality requirements of package software which is sold in commercial software shop. To select the principal quality characteristics of package software, an user survey was conducted for a quality model developed based on the international standards and the previous research. The software user is divided into three groups: the general user, the expert, and the developer. Based on the survey results, the top 10 quality characteristics are selected including accuracy, suitability, installability, de-installability, and maturaty. Then, the QFD technique is applied to choose the software quality attributes which have strong correlation with the selected quality characteristics, some of which are traceability, accuracy, modularity, completeness, and self-descriptiveness. The developed procedure can be used in evaluating the quality of package software with lower costs and efforts.
