This study is analyse method for Industrial disester prevention of E-9 foreign workers. To do this, We adapted tp TRIZ 's creative problem solving theory and AHP, QFD. TRIZ is determined some parameters for problem solving and selected the inventive principles for each parameters. So, We made new parameters and inventive principles under theory of the TRIZ process for reduced to the foreign worker's disaster rate. After, The derived parameters and the inventive principles are used to evaluate the importance of factors through the AHP, and determine the weight of the relation through QFD expansion. Finally. this paper applies statistical data according to the determined model process, analyzes the result and proposes improvement method for the prevention of disaster of foreign workers.

최근 들어 연구기관 및 기업에서 특허 출원 및 등록이 지속적으로 증가함에 따라 특허 관련 비용뿐만 아니라 특허의 양적 질적 관리도 매우 중요한 요소로 대두되고 있다. 따라서 기업 및 기관이 보유하고 있는 많은 특허 중에서 활용 목적에 맞는 우수 특허를 선별하고 관리하는 것이 특허경영의 한 방안으로 강조되고 있다. 본 연구는 기업이 보유하고 있는 특허를 대상으로 QFD를 적용하여 가치 있는 우수 특허를 효과적으로 선별하는 방안을 제시하였다. QFD를 이용하여 특허를 분류하고 품질을 정량적으로 평가하기 위해서 우선 특허에 대한 기업의 요구사항 및 특허품질 특성지표를 도출하였다. 기업의 요구사항의 경우 AHP의 쌍대비교 방식으로 중요도를 결정하였으며, 이를 바탕으로 고객의 요구를 충족시킬 수 있는 특허지표의 값을 결정하고, 이에 대한 해석 및 활용방안에 대해서 논했다. 본 연구에서 제시한 우수특허 선별 방식을 실제 기업의 보유 특허에 적용하여 결과를 비교 분석하였으며 개별 특허지표 및 특허복합지표를 통해 우수 특허를 비교적 손쉽게 선별할 수 있음을 보여 주었다.

This paper presents a tool called Quality-Cost optimization system (QCOS), which integrates Multi-Objective Genetic Algorithm (MOGA) and Quality Function Deployment (QFD), for tradeoff between quality and cost of the unitized metal curtain-wall unit. A construction owner as the external customer pursues to maximize the quality of the curtain-wall unit. However, the contractor as the internal customer pursues to minimize the cost involved in designing, manufacturing and installing the curtain-wall unit. It is crucial for project manager to find the tradeoff point which satisfies the conflicting interests pursued by the both parties. The system would be beneficial to establish a quality plan satisfying the both parties. Survey questionnaires were administered to the construction owner who has an experience of curtain-wall project, the architects who are the independent assessor, and the contractors who were involved in curtain-wall design and installation. The Customer Requirements (CRs) and their importance weights, the relationship between CRs and Technical Attributes (TAs) consisting of a curtain-wall unit, and the cost ratios of each components consisting curtain-wall unit are obtained from the three groups mentioned previously. The data obtained from the surveys were used as the QFD input to compute the Owner Satisfaction (OS) and Contractor Satisfaction (CS). MOGA is applied to optimize resource allocation under limited budget when multi-objectives, OS and CS, are pursued at the same time. The deterministic multi-objective optimization method using MOGA and QFD is extended to stochastic model to better deal with the uncertainties of QFD input and the variability of QFD output. A case study demonstrates the system and verifies the system conformance.

With the recent announcement of the WCAG2.2 Work Draft of the W3C, revision of the WCAG2.2 guidelines will be made soon. Consequently, the revision of KWCAG2.1 in response to changes in the domestic and international environment of web accessibility is urgent. The revision primarily involves development and selection of web accessibility evaluation items. In this study, the efficient procedures and useful methodologies for developing and selecting the evaluation items are to be presented. FGI (Focus Group Interview) has been devised to reflect every stakeholders opinion fairly. GT (Group Technology) has been applied to expedite the revision processes particularly in the FGI. QFD (Quality Function Deployment) method plays an important role in investigating the relationship between evaluation items and its characteristics, and in analyzing the importance and priorities of each item. This study proposes 5 principles, 17 guidelines and 39 evaluation items which can be used for the revision of KWCAG 2.1. This study is expected to be of great help in establishing the KWCAG 2.2 in the near future.

The purpose of this study is to explore the applicability of QFD to product development of clothes by empirically applying it to development of a specific clothes, middle and elderly women’s formal knitwear. The voices of customers(VOCs) for formal knitwear was collected through in-depth interviews with 25 customers, shop masters, and designers. Also, questionnaires of which respondents were 230 customers were used to rank the importance of the items of VOC. A QFD team of 10 knitwear experts implemented the task of translating VOCs into design attributes and measuring the values of the relationships between VOCs and design attributes. Importance ranking of the items of design attributes was obtained based on Lyman's method. The results of this study were as follows. First, the customer requirements for formal knitwear were classified into five dimensions, that is, symbolism, aesthetic, fitness, usefulness, and maintenance. Second, the descending order of the necessity of improving the quality was maintenance, aesthetic, fitness, usefulness, and symbolism. Third, three-staged design attributes were obtained as a result of translating of VOCs into design attributes. Lastly, the descending order of the importance of design attributes was "sorts of yarn", "sorts of color jacquard", "color", "tone", "ease", etc.

In this study, the design concepts for Intelligent Hospital are derived using the Quality Function Deployment(QFD) and System Requirement Analysis Method. First, requirements for important elements of Intelligent hospital are defined. Second, similar systems are compared and user requirement are refined. Through this process, operational requirement for Intelligent Hospital are defined by combining user requirements and similar systems. To analyze operational requirement, the QFD of the system engineering approach are implemented. Alternative design specifications are constructed by implementing the QFD results by building the Morphological Matrix. Various concepts that satisfy the system requirement are derived. Finally the best design concept are obtained using the Pugh concept selection matrix.

We achieved a Quantitative economic growth through rapid developed in 1970' and 1980'. It was confronted after IMF crisis that we needed to improve the past economic policy and the industrial structure. In line of that, the problem of the industrial structure like huge accidents of 1990' converted the recognition of safety. And to improve the conversion, the research of a safety management was needed. In this paper, we thought 4M1E(Man, Machine, Method, Material, Environment) as the cause of accident using the principal of process, assuming that output is accident. Applying 4M1E to the structure of QFD(Quality Function Deployment), we propose the safety function deployment, which has the flow line as followed; demand safety, safety characteristic, direct cause, 4M1E and safety management.
