There are many quality control(QC) tools useful for solving quality problems. In this paper, QC 7 tools, new QC 7 tools, and other quality tools are first compared with respect to their frequency of use. We suggest an integrated problem-solving procedure to systematically deal with various quality problems. For each step a streamlined flow chart is presented to help the practitioners to adopt relevant tools depending on certain situations they face. The procedure will help quality practitioners solve field quality problems.

The purpose of this paper is to propose the effective guidance of Quality Circle(QC) activities. Since 1975, variety of organizations in Korea have widely implemented QC activities for their management systems. The industries have enthusiastically used QC activities and were influenced from them. However, the academics were less interested in this subject, as a result, there were no systematic guidances for QC activities. Thus, in this paper, the effective guidance for QC activities were suggested which were based on the survey from QC proceedings presented in the companies, in the local areas and the national wide contests. As a result, the first main issue is to pick repeated mistakes up during the process period such as unmatched the causes and effects relations in characteristics diagrams, improper selection of important control items in Pareto diagram and so on. Secondly, how to overcome statistics and use them for QC activities. Thirdly, to remind team members about Quality Control 7 tools. Finally, Minitab(Release-13) software has been found that it is not matched with using Korean Standards(KS).

Recently, creative innovation has become a major topic in management innovation and due to this, various researches on its need and methodologies are being performed. According to previous studies on ambidexterity, explorative innovation is closer to divergent and right-sided brain, while exploitative innovation is closer to convergent and left-sided brain. Five attributes of the questionnaires were developed based on right-sided and left-sided brain theory. Also, 25 problem solving tools were selected according to previous studies. QC 7 Tools and new QC 7 Tools were frequently used in Six Sigma projects. Other 11 problem solving tools were selected with consideration on its usage frequency. Survey questionnaires were distributed to 25 Six Sigma consultants and 22 were retrieved for this study's use. As a result, 14 tools were identified to hold exploitative attribute while 11 tools were identified to hold explorative attributes.

신제품 개발과정에 대한 전반적인 흐름에 대해서는 기존의 연구가 다양하게 이루어져왔으나 구체적으로 어떠한 방법론이나 도구를 사용하여 시행하는가에 대해서는 논의가 미미하였다. 따라서 본 연구에서는 신제품 개발시 시장에서 생존가능한 제품속성과 가격을 결정하는 방법으로서 계량경제학적 헤도닉 방법론을 대체할 DEA 모델을 제안하고자 한다. 제품속성과 가격이 이루는 곡면이 유연하게 형성되도록 QC-DEA를 사용하고 거기에 제품속성에 대한 소비자의 선호체계를 반영하기 위하여 AR을 도입하여 AR-QC DEA라는 모델을 만들었다. AR-QC DEA는 모수적 방법론의 한계를 극복할 뿐만 아니라 제품마다 다른 잠재가격을 제시하기 때문에 신제품 개발시 제품속성과 가격의 조합에 대해 많은 정보를 제공해 줄 수 있고 또한 그렇게 만들어진 신제품이 과연 시장에서 생존할 수 있는가를 손쉽게 모의테스트 할 수 있다. 마지막으로 노트북 컴퓨터 제품에 대한 AR-QC DEA의 실증연구를 통해 AR-QC DEA가 충분한 현실설명력을 가짐을 볼 수 있다.

건설 품질관리는 건설 프로젝트의 성공적 수행을 위한 필수요소이다. 최근 ICT 기술 적용이 활성화 됨에 따라 현장 검측 업무에 첨단 기술 및 장비를 활용하기 위한 다양한 시도가 이루어지고 있다. 그러나 개별적 검측업무에 대한 첨단기술 적용에 앞서 전체 검측업무를 선제적으로 계획하는 것이 매우 중요하다. 본 연구의 목적은 건설 검측업무에 첨단 기술 및 장비를 활용하기에 앞서 검측대상과 관련 정보를 명확히 도출하기 위한 데이터베이스와 그 데이터 베이스를 활용하기 위한 알고리즘을 개발하는 것이다. 또한 건축 시공계획에 따라 검측업무에 해당하는 액티비티를 자동 생성하기 위한 프레임워크를 제안하였다. 그 방법으로 국토교통부에서 고시한 책임 상주 감리 체크리스트의 검사 항목을 바탕으로 검측 대상, 검측 시기, 검측 방법, 검측 범위, 검측 제약요소를 분석하고 분류하였다. 본 프레임워크는 철근 콘크리트 공사 사례에 적용되었다. 개발된 건설 검측 업무 액티비티 자동 생성 프레임워크는 건축 시공을 위해 사용하는 공정관리 프로그램, 검측업무 및 검측기술을 연계하는데 적용할 수 있다. 향후 다양한 건설 프로젝트의 검측 업무 시, 액티비티 자동 생성 및 자동화를 위한 기초로 활용될 것으로 판단된다.

공학교육인증에 있어서 프로그램학습성과는 공학교육의 질적 향상 정도를 판가름하는 중요한 기준이며 가장 핵심이 되는 부분이다. 한국공학교육인증원은 프로그램학습성과를 공과대학 졸업생들이 졸업과 동시에 반드시 지녀야 하는 핵심 역량 12가지로 규정하고 있으며 인증을 받고자 하는 모든 공학교육프로그램은 전공 관련 지식을 포함하여 이를 달성하기 위한 교육과정을 구축하고 달성 및 지속적인 개선을 하고 있는지의 여부를 보이기를 요구하고 있다. 여기서 프로그램학습성과는 크게 두 가지를 만족시켜야만 하는데첫째, 공학프로그램은 졸업생이 12가지 능력과 자질에 대해 달성하고 졸업함을 보장할 것에 대한 요구와 둘째, 12가지 능력 및 자질을 교육시키는 프로그램의 교육 수준의 지속적인 개선이다. 따라서 본 연구의 목적은 이러한 한국공학교육인증원의 취지에 맞는 평가를 실시하기 위해 프로그램학습성과 평가의 CQI와 QC를 실현을 위해 갖추어야 할 체계인 구축 모형을 소개하고 한국공학교육인증원의 기준에 알맞은 실천전략을 제시하고자 한다.

This research paper introduces the application and implementation of medical decision metrics that classifies medical decision-making into four different metrics using statistical diagnostic tools, such as confusion matrix, normal distribution, Bayesian prediction and Receiver Operating Curve(ROC). In this study, the metrics are developed based on cross-section study, cohort study and case-control study done by systematic literature review and reformulated the structure of type I error, type II error, confidence level and power of detection. The study proposed implementation strategies for 10 quality improvement activities via 14 medical decision metrics which consider specificity and sensitivity in terms of ${\alpha}$ and ${\beta}$. Examples of ROC implication are depicted in this paper with a useful guidelines to implement a continuous quality improvement, not only in a variable acceptance sampling in Quality Control(QC) but also in a supplier grading score chart in Supplier Chain Management(SCM) quality. This research paper is the first to apply and implement medical decision-making tools as quality improvement activities. These proposed models will help quality practitioners to enhance the process and product quality level.

Properly designed and well-executed services enable e-commerce companies to capture the unique needs and preferences of customers, help them build customer loyalty, and thereby, strengthen their competitiveness in the marketplace. An object of this study is the new open-market company and it has only 3 percent of the market share. Therefore, it is needed to raise the market share by improving the service qualities. This article presents a six sigma project for service quality improvement in the open-market company. This study was carried out based on five steps of DMAIC which is six sigma technique. First, a defect rate was defined as unsatisfaction rate. In addition, 50-people data was analyzed and it was shown that the defect level was 2.5 sigma level. In this study, in order to raise the sigma level, novel eight action items were determined based on SIPOC, FDPM, cause and effect diagram, matrix chart, Pareto chart and statistical analysis.

The paper aims to apply a model of continuous quality improvement (CQI) to Taiwan provincial Pin Ton hospital. Tools of quality control were used both total quality management (TQM) and quality control circle (QCC) in order to approach the objective of ${\ulcorner}$higher quality, higher efficiency, lower cost${\lrcorner}$. During two years, this hospital has organized thirteen QC circles that were classified three categories according to that objective: four circles work for higher quality; the other four circles work for higher efficiency; five circles for lower cost. After implementation, several results were found from two viewpoints. From viewpoint of tangibility, one of the most outcomes is to reduce labor cost from 56 persons to 28 persons of temporary employees. From viewpoint of intangibility, the result was evaluated using radar chart to compare the difference after improvement. This paper is going to report the process of CQI for the hospital management because it is a new issue in Taiwan since 1997
