In this research, we investigate the countermeasure of Product Liability through existing research or books for reference about PL and ISO 9001 : 2000 quality management system. And we analyze relation between PL system and ISO 9001 : 2000 Quality Management System after compare ISO 9001 : 2000 and ISO 9000 : 1994. base on this analysis, we integrate the Quality Management System of company and an important factor of PL system in accordance with the product liability law. So we present a general improvable scheme of ISO 9001 quality management system that reduces overlap of quality business and utilize efficiently.

This paper is purpose to research system use, ubiquitous convenience considering ubiquitous system and system use, ubiquitous convenience considering user satisfaction. In this study system use was signification influenced by system quality, instantly connectivity, and user satisfaction use was signification influenced by system quality, information quality. But system use was not signification influenced by information quality, service quality and ubiquitous convenience was not signification influenced by service quality, instantly connectivity.

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.

This study introduced the compact grouting method that can be used for improving soft ground and restoring buildings with unequal subsidence. The pump used in the traditional compact grouting method is a system that injects one hole each, which reduces the construction efficiency, and the analog injection method manually manages the construction by field workers, making it difficult to manage consistent quality. Pump and quality control system were developed to solve problems in existing construction. Since field supervisor determines amount of injected materials by using analog equipment and controls manually, it is difficult to manage consistent quality of construction. Therefore, the quality control system was developed in order to solve that problem. The quality control system consists of automatic mixing system of injection materials, multiple simultaneous injection pumps, and injection management monitoring system. Performance of the quality control system was verified through on-site testing, and ground improvement performance was verified through quality testing after testing and testing of the compact grouting method. Therefore, it is expected that the integrated quality control system developed will improve the quality assurance and efficiency and stability of construction at sites where construction and quality verification are difficult.

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.

In this study, water quality prediction that is necessary to water quality forecasting system is performed using 2-D river analysis models RMA-2 and RAM4. RAM4 is suitable to water quality forecasting system cause it is possible to put in the pollutants as a mass type boundary condition. Instant injections of pollutants at Yongdamdaegyo Bridge in Namhangang River are simulated and the behavior of pollutant cloud is observed. The effects of water quality accident to Paldang 2 water intake plants in Paldangho Lake is analyzed with time variation. And extra flow simulation is performed for mitigation of pollution. Several cases of water quality forecasting system at home and abroad are investigated and the direction of water quality forecasting system is presented.
