In companies competing for today's information society, Data quality deterioration is causing a negative influence to generate company competitiveness fall and new cost. A lot of Preceding study about data qualify have been proceeded in order to solve a problem of these data qualify deterioration. Among the sides of data qualify, it has been studied mainly on qualify of the data valve and quality of data service that are the results quality concept. However. this study studied structural qualify of the data which were cause quality concept in a viewpoint of meta data management and presented data quality management maturity model through this. Also empirically this study verified that data quality improved if the management level matured.

The concept of producer's tolerance, in contrast to the consumer's tolerance, is a natural consequence of continuous loss functions. It is based on the premise that any unit product whose quality characteristic deviated from its traget value inflicts a loss, and that this less is a continuous monotonically increasing function of the magnitude of deviation. This concept of the emphasis on loss function to improve quality of products on the side of customer is introduced by Taguchi. This paper considers the problem of determining the optimum producer's tolerance by continous loss fuction of Taguchi and proposes a probablistic model for the problem. The difference between the proposed probablistic approach and the approach taken in Taguchi is also pointed out.

The concept of e-Government was first developed and implemented in industrialised countries. Consequently, it should not be assumed that this concept is automatically appropriate for developing countries. This study aims to examine the roles of perceived support quality and support satisfaction in the context of government-to-citizen (G2C) transactions towards behavioural intention and usage in developing countries. To test the proposed model, the official website of Kuwait Government Online Services (KGOS) was selected. A survey with a total of 628 responses was analysed using Structural Equation Modelling (SEM) to investigate the goodness of fit of the model and the underlying indicators. The findings confirm the significance of support quality perceived by citizens and provide insights to explain citizens' intention to use e-Government systems.

Nowadays, a strategy of the self-optimizing machining process is an imperative approach to improve the product quality and increase productivity of manufacturing systems. This paper presents a concept of self-optimizing forming system that allows the forming system automatically to adjust the forming parameters online for guarantee the product quality and avoiding the machine stop. An intelligent monitoring system that has the functions of observation, evaluation and diagnostic is developed to evaluate the pully quality during forming process. Any abnormal variation of forming machining parameters could be detected and adjusted by an intelligent control system aiming to maintain the machining stability and the desired product quality. This approach is being practiced on the pully forming machine for evaluating the efficiency of the proposed strategy.

This paper develops and defends the concept of reference-quality in consumer choice, demonstrating its impact on aggregated market demand. The concept of reference-quality refers to an internal standard against which observed qualities are compared in consumer choice behavior. In doing so, we examine and reveal the formation mechanism and the structure of reference-quality in the U.S. wireless phone market. Consequently, we recognize and introduce a brand-specific reference both in price and product quality in aggregated product demand which enable us to measures the responsiveness of market demand to the innovation of a certain brand.

In this paper, we present a useful system to manage the quality documents, using the concept of hypertext in HANGUEL wordprocessor, In order to develop this system, we classify all manuals, procedures and forms into files. A relationship chart of these files is constructed and files are hyperlinked according to this chart. We apply this quality document management system using hyper- text to a small precision manufacturing firm by analyzing its all kinds of quality documents. We confirm that this system effectively reduces the handling time of quality documents and supports revising task of quality documents with consistency.

This investigated 205 dental personnel in Daegu and Gyeongsangbuk-do to find out the effects of Dental Hygienist(Nurse's Aide)'s coaching leadership on job satisfaction, motivational self-concept and quality of life. the entire average of coaching leadership was 2.67 On 5 point scale, development coaching 2.61, relationship coaching 2.61. "my boss fully provides me with training opportunities for my development' had the lowest 2.50. As for coaching leadership according to general characteristics, had the highest average those aged of 20-25years old, work experience of 1-5years, single, salary less than 20 million, female immediate superior, immediate superior aged 20-30years old, position of immediate superior is team head, senior dental hygienists(p<.05). The three criteria had positive correlation with coaching leadership(p<.05). Therefore, Right coaching leadership increases job satisfaction, improves motivational self-concept for increasing individual development, raises quality of life.

In automotive industries, reusability of product information is increasing through database construction of previous product data. The product data is stored by data quality management in product information systems. For naval ships, have the functional similarity by the ships of the same classification and class, that are built by series. Information of hull structures as well as embarked equipments are similar. So it would be effective to use database systems that are considered product information quality of previous ships in design and production processes. In this paper we discuss product information quality in database construction of naval ship product models. For this, we propose a basic concept and reference model for data quality verification. Based on this concept, A verification guideline is defined and it is applied for the case study of the digital naval ship which was built to the naval ship product model.

The purpose of this study is to propose a facility layout design algorithm based on artificial intelligence concept, and then to develop a computer program which is more practical than any other conventional facility layout design systems. The algorithm is composed of five step layout procedures; knowledge and data input, knowledge interpretation, priority determination, inference of layout design, and evaluation, In the step of priority determination, the algorithm is divided into single row and multi row layout problem. In the step of inference of layout design, alternatives are generated by constraints-directed reasoning and depth first search method based on artificial intelligence concept. Alternatives are evaluated by the moving cost and relationship value by interactive man-machine interface in the step of evaluation. As a case study, analytical considerations over conventional programs such as CRAFT and CORELAP was investigated and compared with algorithm propsed in this study. The proposed algorithm in this study will give useful practical tool for layout planner. The computer progran was written in C language for IBM PC-AT.

In the light of globalisation and the international division of labour, the article will stress the importance of a new conception of quality management, focusing more on the social and environmental aspects of quality in global supply chains with a particular emphasis on suppliers' perspectives. The increasing focus on corporate social responsibility, business ethics, corporate citizenship, sustainable development etc. indicates that managers have failed to see social and environmental aspects of the production as an integrated part of quality.
