Data mining is a useful tool for analyzing data from different perspectives and for summarizing them into useful information. Recently, the data mining methods are applied to solving quality problems of the manufacturing processes. This paper discusses the problems of construction of a quality mining system, which is based on the various data mining methods. The quality mining system includes recipe optimization, significant difference test, finding critical processes, forecasting the yield. The contents and system of this paper are focused on the TFT-LCD manufacturing process. We also provide some illustrative field examples of the quality mining system.

Purpose: This article aims 1) to propose improvement directions of the certification by recognizing the quality management practices based on the analysis of the audit results of the military contractors and 2) to suggest some ideas on quality audit planning preparation to help the government quality assurance representatives. Methods: Based on the nonconformity report of the defense quality management system (DQMS) requirements, frequently occurring requirement components are found and summarized. Three hypothesis testings are executed to check whether the maturity levels of the quality management systems are influenced by the company size, weapon tye, and company type, regarding the nonconformity frequency as dependent variable. Results: Nonconformity occurs most frequently in the order of product realization, measurement analysis and improvement, management responsibility, resource management, and quality management system. Nonconformity reduces when the company size increases, for the guided weapons, and in the defense companies. Conclusion: Since small-sized companies are inferior to larger companies with respect to the DQMS maturity level, more support should be provided to these small-sized companies which produce military supplies.

본 연구에서는 연약지반의 개량 및 부등침하가 일어난 건물의 복원 등에 사용할 수 있는 컴팩션 그라우팅 공법을 소개하였다. 기존 컴팩션 그라우팅 공법에서 사용되는 펌프는 1공씩 주입하는 시스템으로 시공 효율성이 저하되고,아날로그 주입방식으로 현장 작업자가 수동으로 시공을 관리하여 일관된 품질관리가 어려웠다. 기존 시공에서의 문제점을 해결하기 위하여 펌프와 품질관리 시스템을 개발하였다. 품질관리 시스템은 주입재료의 자동 배합 시스템, 다중 동시 주입 펌프, 주입관리 모니터링 시스템으로 구성하였다. 현장 시험을 통해 품질관리 시스템의 성능을 검증하였고 컴팩션 그라우팅 공법의 시험시공 후 품질 시험을 통하여 지반개량 성능을 확인하였다. 따라서 개발된 통합 품질관리 시스템을 활용한다면 시공 및 품질 확인이 어려운 현장에서 일관된 품질의 보장과 시공의 효율성 및 안정성을 향상시킬 수 있을 것으로 기대된다.

It is worthwhile to know how the quality inspection is practised to assure the product quality for the export articles, and what problem is resulted from the current quality inspection system for the export articles. The aim of this paper is to survey the status of quality inspection system for the export articles and to design the quality inspection system for the export articles so as to not only solve the problems arising from the current system but also improve the product quality for the export articles. To find out the facts the survey is conducted by sending a prepared questionnaire both to the export industries and to the export quality inspection agencies authorized by the Ministry of Commerce and Industry. The export industries surveyed are selected to provide broad representation with respect to the type of industry as well as to the size of company. The survey shows that about 50 percent of the responding industries desire to discontinue the current quality inspection system for the export articles, and other 50 percent of them desire to continue it until all the export industries can make the best use of quality control techniques.

Recently, in accordance with the development of IT technology, it is prevalent for power quality monitors to be connected to each other via networks and share their data because such networks provide system-wide insights to customers concerning power quality. Those systems can alarm and display power quality events for the convenience of customers. However, if a power quality event occurs, it is difficult for customers to determine its cause and solution because the systems do not provide appropriate power quality diagnosis functions. The power quality management system presented in this paper has been developed to provide customers with various power quality diagnosis functions so that they can cope well with power quality problems with the right measure in the right place. This paper presents the structure and functions of the developed power quality management system and shows some results of the power diagnosis functions.

A system Integrator (SI) makes a consortium with multiple providers of hardware and software solutions to sell an information system. The success of information systems (IS) mainly depends on establishing a trustful relationship between SI supplier and client, and delivering high-quality system. However, the determinants of trust and system quality have been investigated mostly from the perspective of s ystem buyers rather than system sellers. This study examines the influence of key variables that SI can handle to improve trust and system quality which finally leads to user satisfaction toward SI. This study adopts resource complementarity, user participation and information sharing as the key variable then builds a research model to explain their relationships to user satisfaction. Respondents are recruited from 251 firms that have built any information system in recent two years in South Korea. Results of partial least square (PLS) modeling analysis show that both resource complementarity and information sharing have positive relationships with trust. Also the relationships between trust, system quality and user satisfaction toward S.I are supported. In addition, the mediating roles of trust and system quality are identified. We discussed some of the key managerial and theoretical implications of the paper and suggested further research directions.
