In 1999, Six Sigma was introduced into Korea and after that it had general influence on company-wide management system. Quality Circles apply the various quality problem solving techniques such as QC 7 Tool, New QC 7 Tool, and statistical methods to rationalization, improvement in the shop floor. This paper empirically investigates the effects of Six Sigma on Quality Circles by analyzing the difference of problem solving technique's use. The number of teams employed in this study is 342, which participate in National Quality Circles Contest from 1997 to 2002 in Korea.

Data on nearly one hundred thousands of Korean quality circles, registered with KSA(Korean standard association), are classified by regional groups, size, and industry. The classified data are analyzed in order to investigate the actual state of quality circles. Some international comparisons such as managerial objectives for introducing quality circles are also included.

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

Through literature review, this paper studies the development stages of Quality Circles and 6 sigma which are representative of domestic quality improvement activities. Thus, using the judgement guideline of Van der Wiele's classification for fad, fashion, and fit, the development stages for existing researches of Quality Circles and 6 sigma are qualitatively classified by research themes. In addition to, academic and business perspective are examined to grasp a current position of domestic quality improvement activities. As a result of the findings of current development stages of quality improvement activities, domestic Quality Circles which are not going to move on a fit stage are currently classified as the stage between fashion and fit, and 6 sigma activities are currently classified as the stage of fashion.

Purpose: This research is to find the general and somewhat prevailing problems in quality circle papers. Many quality circles try to benchmark awarded papers even though they may have common problems. By pointing out popular problems in papers, many quality circles hopefully could be guided to the right direction in working out improvement actions. Methods: Many papers awarded in national quality circle conferences are deeply analyzed to figure out common problems. 69 recent papers are analyzed step by step and the most important and frequently occurring problems in each step are indicated. Results: Many prevailing problems are found in each step of QC stories. Especially finding themes, Grasping status quo, Cause analysis, Setting targets, Development of and Implementing counter attacks are the most common areas that have problems. Conclusion: Some problems are already too popular to be recognized as problems. In this paper those problems are logically criticized and thereby right directions for future quality circle activities are proposed.

The purpose of this study is to find the problems, which occurs in the course of the acceptance and the propulsion of the Q. C. circle, the accomodational attitude, and the desirable circumstances for the Q. C. circles, to be of help to settle firmly the "Sae-ma-eul" (New-Community) Movement in the industrial fields, and Q. C. circle and to fix the Q. C. of Korean style through the investigation of the 310 Q. C. circles, which was selected at random from entered circles to the Q. C.

The integration of Quality Circles and Six-Sigma has gained attentions for the attainment of enhanced customer satisfaction, costs reduction, and improved business performance. The purpose of this paper is to verify the benefit from the integration of Quality Circles and Six-Sigma by applying the integrated process for an alcohol manufacturing line. In the integrated process, we used the first three steps of Six-Sigma of Define, Measure, and Analyze(D-M-A) and then applied the concept of Quality Circle, which has good performance in the Improvement and Control(I-C) process. For the selection of the theme of quality circles, Analytic Hierarch Process(AHP) is used, and we also employed the experimental design, which is designed to find an optimal operating condition. Furthermore, the results of the economic analysis confirm that the integration process would be successful in reducing the incidence of defects and the quality cost.

In this age of infinite competition, quality control plays a huge part in deciding whether companies survive or not. In order to successfully solve the fundamental questions of quality in corporate management under the given circumstances, I suggest that the followings are vital: 1) continuous training of employees and competence development; 2) advocating employees' voluntary involvements and their will to work; 3) revitalizing quality circle activities. Activities of quality circles, which are organized to work out fundamental problems within the corporation, are important in renovating the existing administration. Thus, the purpose of this study is to understand the degree of influence quality circle activities have on the management outcome of the corporation by analyses of actual proofs, and to raise the importance of these activities. Moreover, it purports to provide the foundation for domestic companies to move toward becoming competitive advantage organizations by endowing them with the motivation to activate quality circles.
