The importance of design value engineering in construction projects recently is rising, which deal about in reduction of cost and improvement of quality. Especially, From half of this year 2005, It is predicted that the value engineering is necessary to be carried out in the projects having project cost more than 10 billion won. In increasing importance of value engineering, we require a way by which we accomplish value engineering systemically and effectively though it is not common in domestic situation. So, this case study shows a way in carrying out value engineering effectively. As the way is to apply QFD(Quality Function Deployment) in pre-study work of design value engineering, this is expected to contribute as function analysis and reflect the requirement of users or owners.

By conducting multiple regression analysis, we analyzed the major independent factors affecting user convenience and emotional factors, and identified the important functional elements in the design of the VR device, so that the functional elements to be developed can be grasped in advance. As a result of the study, satisfaction of handling of VR bicycle and satisfaction of speed control by paddling were considered as the most important technical factors as independent factors which have the greatest influence on user convenience and emotional factor among technical satisfaction. Also, it is possible to increase the probabilities of successful design by setting a model that predicts user convenience and the emotional part from the technical factors.

This study aimed at the improvement of the conventional methods of Velue Engineering Function Analysis, the most important phase of VE processes, through Quality Function Development and Analytic Hierarchy Process. This study was performed in both theory and study. In the theoretical study, the necessity and the fitness of the connection between VE and QC techniques were studied. The use of Function Requirement Coefficients in Quality Function Development makes the more objective Function Evaluation possible.

The records centers service of public institutions helps efficient work activities of internal users, who actually do the work, and becomes the foundation for strengthening the competitiveness of the institution. Based on QFD technique, one of the quality control techniques, this study was intended to propose a plan to improve the quality of the records center service by analyzing and comparing the quality of the records center service of public institutions. To this end, as a follow-up study of Lee, Su-jin(2018), the research target was expanded to local governments to apply the QFD technique and reconstructed the HoQ based on the results of the expanded QFD application. Moreover, this study suggested measures to improve the quality of service in the records center of public institutions by compiling the implications of comparing the records center service HoQ and prioritizing the technology characteristics of the records center service.

Quality function deployment is an interdisciplinary team process of listening to customers to learn exactly what they want, and then using a logical system to determine how best to fulfill those needs with available resources. It is examined how to extend quality function deployment in this paper. The Pugh concept selection method, ACE(Attribute Categorization and Evaluation) Matrix, and an inventive problem solving method called TRIZ are discussed in relation with quality function deployment.

Although the role of information system has been rapidly increasing in modern management, there have been few researches on the quality assurance in information system. This paper suggests how to apply quality function deployment(QFD) to information system development in order to build up user-centered quality assurance system. The main focus of the paper is how to design the linkages between management strategy, information systems, and the users using quality function deployment.

Wire bonding process in making semiconductor needs the most precise control and Critical To Quality(CTQ). Thus, it is regarded to be the most essential step in packaging process. In this process, pure gold wire is used to connect the chip and PCB(substrate or lead frame). However, the price of gold has been skyrocketing continuously for a long period of time and is expected to further increase in the near future. This phenomenon situates us in an unfavorable condition amidst the competitive environment. To avoid this situation, many semiconductor material making companies developed new types of wires: Au.Ag wire is one material followed by many others. This study is aimed to optimize the parameter in wire bonding with the use of 6sigma and QFD(Quality Function Deployment). 6sigma process is a good means to not only solve the problem, but to increase productivity. In order to find the key factor, we focused on VOB(Voice of Business) and VOC(Voice of Customer). The main factors from VOB, VOC are called CTQ. However, there were times when these main factors were far from offering us the correct answer, thus making the situation more difficult to handle. This study shows that QFD aids in deciding which of the accurate factors to undertake. Normally QFD is used in designing and developing products. 6sigma process is held more effective when it used with QFD.

CBD(Component Based development)가 이미 완성된 소프트웨어 모듈인 컴포넌트들을 특정 목적을 위해 배치하고 조립함으로써 품질 보증된 고생산성의 재사용을 가능하게 됨에 따라, 최근 IT 비즈니스 솔루션 도출을 위한 핵심 적인 기술 전략으로 인식되고 있다. 따라서 영 역에 적절한 컴포넌트의 추출과 개발 및 응용 시스템으로의 전개를 위한 컴포넌트들의 배치와 조립 등을 포함하는 일련의 CBD 프로세스를 실제화 하기 위해서는 아키텍쳐 기반의 접근과 제어가 매우 중요하다. 하지만 대부분의 CBD 연구는 비즈니스 로직들의 기능성을 그룹화한 컴포넌트의 생산에 초점을 두고 있지 컴포넌트간의 상호작용을 명시하는 아키텍쳐 정보의 관리를 간과함으로써 컴포넌트의 조립과 통합을 통한 CBD 시스템으로의 전개는 극히 어려운 실정이다. 따라서, 본 논문에서는 CHD 프로세스 상에서 아키텍쳐 접근의 중요성과 전개 방법을 살펴보고, 컴포넌트 프레임워크(Component Framework)를 위한 아키텍쳐의 계층을 새롭게 재정의 하며 그 의미를 설명한다. 이를 위해 영역 분석 및 설계 정보를 선언적으로 명시하는 수단이며, 도메인 내에서 특정 서비스를 제공하는 컴포넌트간의 일반적 결합 방식의 규정하기 위한 수단으로서 설계 패턴을 이용하여 서비스 아키텍쳐 패턴을 정의하고 실 예로 적용한다.

Spaceborne imaging sensors require periodic calibrations using an on-board calibration device for an image quality of observation satellites. The on-board calibration device consists of a blackbody to provide uniform radiance temperatures and calibration mechanism with a function of stow and deploy to target the blackbody during the calibration. Among these devices, the calibration mechanism is required to implement a fail-safe function to prevent blocking of the main optical path when the mechanism stops at a certain position during on-orbit calibration. In addition, structural safety of the mechanical driving part of the mechanism within the launch environment must be guaranteed. In this study, we proposed a deploy/stow-type calibration mechanism that provides launch-lock and fail-safe function. The effectiveness of the functionality of the proposed mechanism was validated through functional test using engineering model.

In this paper, the QFD(quality function deployment) technique is used to acquire the quality requirements of package software which is sold in a 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. The method of QFD is applied to choose the software quality attributes which have strong correlation with the selected quality characteristics.
