This study proposes Environmental Quality Deployment (EQD) by combining an instrument for measuring customer satisfaction (ENVIROQUAL) with a standard tool of product design in manufacturing called quality function deployment (QFD). The EQD presents the conceptual map of House of Environmental Quality as a means to implementation to help a company know what customers perceive as important in making environmentally friendly product and provide a framework for the translation of customer satisfaction into identifiable and measurable conformance specifications for environmentally friendly product design.

Nuclear project company establishes and maintains its QA system in the conformance with applicable Codes & Standards and contract provisions. Certifying agency(e.g., Korea Electric Association) or project owner appraises the effectiveness of the company QA system by surveying or auditing it. However, although the company fulfills the requirements of this survey/audit, the capability level of its nuclear QA system is not appraised numerically and developed in that KEPIC QAP-1, used by the company as a nuclear QA guidebook, does not describe an approach for managing the capability level of the QA system. This study evaluates the characteristics of QAP-1 from the viewpoint of SE-CMM(Capability Maturity Model for Systems Engineering) in order to suggest a possible solution.

Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

IEC 61850 based substation automation system mainly consists of a various of protective and control IEDs. In order to implement the system, All of them should require the performance verification of IEC 61850 communication services for the assurance of interoperability throughout the digital network. This paper shows a research result on the testing method of IEC 61850 control communication interface of IEDs according to IED IEC 61850 conformance test procedures.

본 논문은 IEC 61850 기반의 전력IT기기에 대한 시험 및 평가방법에 대해 다루었다. 여러 제조업체에서 제작한 IEC 61850 기반 전력IT기기는 현장과 같은 실제 사이트에서 구성된다. 현장시험(SAT: site acceptance test)은 운전하기 이전에 고객에게 확신을 주기위해 사이트에 설치된 모든 장비에 대해 시험 및 평가를 수행한다. 적합성 시험(conformance test)은 효율적인 현장시험을 위해서 수행해야 한다. 그러나 적합성시험을 통과한 장비일지라도 통합작업, 검수시험 및 운전하는 경우 문제가 발생할 수도 있다. 따라서 통합작업, 검수시험 및 운전하는 경우에 문제점을 최소화하기 위해 적합성시험뿐만 아니라 상호운용성 시험을 수행해야 한다.

지상파 DMB가 널리 보급되고, 이를 활용한 재난경보서비스가 시험방송을 준비 중이다. 그러나 검증되지 않은 수신기들이 대량으로 출시되어 BIFS 대란과 같은 문제점도 발생하였다. 재난경보방송은 정확한 정보 전달이 매우 중요하므로, 이와 같은 문제가 발생하지 않도록 하기 위한 '지상파 디지털멀티미디어방송(DMB) 재난경보방송 수신기 표준적합성 시험'을 두고 있다. 이 표준을 분석한 결과 추가되어야 할 시험 방목이 몇 가지 발견되었다. 이 논문에서는 '지상파 디지털멀티미디어방송(DMB) 재난경보방송'의 메시지 포맷을 분석하여 각 필드가 모순되는 경우와, 사용하지 않는 값이라 명시하였으나 시험 항목에 누락된 부분을 파악하여 보충하였다. 이러한 시험 항목을 이용하면 표준을 보완하고, 결함이 더 적은 수신기를 개발하는데 도움이 될 것이다.

Quality is defined as several terms of fitness for use, conformance to requirements or specification, and loss of social effect. And the quality can be classified into design, production and service quality according to its formation of product (or servece). To be satisfactory product, the product must be controlled to maintain the specified level of quality at the whole life cycle of R&D step through disposal step. And the wrong design is one of the great source of cost. Therefore, the quality assurance on the R&D step is very important. This paper suggests a general procedure for the R&D quality assurance and discusses the methods for the reliable design. And a telecommunication equipment is considered as an applied example. Finally, it is discussed some subjects on the R&D quality assurance as further researches.

국내의 한 인터넷 경매업체는 "대한민국 국민 5명 중 한명은 이미 자신들의 경매를 경험해 보았다." 라고 광고할 정도로 웹 기반의 전자상거래는 이미 우리의 일상생활에 깊이 파고든 상태이며, 이제는 단순한 웹상의 전자상거래 뿐이 아닌 웹 서비스 개념의 시대가 현실화 되고 있는 시점이다. 이러한 흐름 속에서 XML은 데이터만을 따로 표현할 수 있다는 특성에 의하여 업계의 표준으로 떠올랐으며, 자연스럽게 이와 더불어 XML의 보안기능은 주목을 받고 있다. XML 전자서명, XML 암호화, XML 키 관리 명세는 주요한 XML 보안기술로서 표준화가 진행되어 많은 부분 완료되었다. 이에 따라 표준을 구현한 제품들이 출시되어 상용화되고 있다. 이러한 제품들은 표준에 적합하도록 개발되어야만 제품의 목적인 안정성과 각 제품들 간의 상호운용성에 있어서의 신뢰도를 검증받을 수 있다. 이에 본 논문에서는 XML 암호화에 대한 표준 적합성 시험 방법을 제시하고 시험도구를 구현하였다.

The implementation of a screening procedure for removing non-conforming products has become a common practice especially in high-tech manufacturing industries. Screening procedures involve a measurement on the quality characteristic of interest since decisions regarding the conformance to specifications are usually made on the basis of the realization of measurement. A significant variability in measurement procedures may result in the misclassification of an outgoing product (that is, falsely accepting defectives or falsely rejecting conforming items), which may lead to wrong interpretation on product quality, It may thus be necessary to consider the impacts of misclassification errors due to measurement variability when designing screening procedures. Along this line, this article investigates the design of screening procedures based on the assessment of misclassification errors. The main objective is to determine the screening limits on measured values so that two types of misclassification errors may properly be compromised.

Most of systems engineers make a traceability matrix and attach it to their technical documents as a result of systems engineering activities. I have been working in the field of systems engineering for many years and have been watching traceability matrices created by systems engineers or developers from various companies. I have been thinking that some of them are not suitable in terms of purposes of traceability matrix. In this paper, I would like to suggest a right template for the traceability matrix in conformance to traceability purposes. The key is that traceability matrix should be created from higher level of requirements to current level of requirements.
