  • This study presents an analysis of healthcare quality indicators using data mining for developing quality improvement strategies. Specifically, important factors influencing the inpatient mortality were identified using a decision tree method for data mining based on 8,405 patients who were discharged from the study hospital during the period of December 1, 2000 and January 31, 2001. Important factors for the inpatient mortality were length of stay, disease classes, discharge departments, and age groups. The optimum range of target group in inpatient healthcare quality indicators were identified from the gains chart. In addition, a decision support system was developed to analyze and monitor trends of quality indicators using Visual Basic 6.0. Guidelines and tutorial for quality improvement activities were also included in the system. In the future, other quality indicators should be analyze to effectively support a hospital-wide continuous quality improvement (CQI) activity and the decision support system should be well integrated with the hospital OCS (Order Communication System) to support concurrent review.

  • Recently, water quality problems are emerging as important social issues since water quality in rivers and lakes are significantly deteriorated. Thus, an accurate prediction system on reservoir water quality is required, as well as an integrated system which can provide a solution for taking away contaminated materials. This research aims to develop an intelligent decision support system, which uses a GIS enabling management and spatial analysis. The developed system is a prototype that can be applied into real spot. This research area includes the following main subjects; system analysis and design, geometry data collection and database implementation, data acquisition and analysis on reservoir water quality, interface design and development GIS, and development of an expert system for water quality forecasting by WASPS.

  • The business is faced with the situation must improve a power in an increasingly competitive environment due to the recent rapid advance in information technology and the opening and expansion of global market, fast technological change, and various customer demand. The rapid change in information technology is having an effect on not only all the processes to develop products, but information contents that is provided for the purpose of customer value, and the appearance of products. In other words, the information technology is being recognized as a very important factor among other factors for companies to enhance their competitiveness. In addition, it is more efficient to focus on key factor to maintain the competitive advantage on the using of information technology by outsourcing information systems, rather than by operating the systems under their own. Since the global financial crisis, the long-term recession has been increasing companies who is ready to adopt outsourcing or adopted already. This study is to understand the environment and unique characteristics of outsourcing services and related industries focusing on information system operation and management in information outsourcing services, and is to set the concept needed through my theory that is connected to the service quality and customer satisfaction. A lot of business wiew the improvement of service quality and ensuring customer satisfaction as the major factors of business growth, and lots of ongoing studies have focused on service management in the Information outsourcing service industry. Yet few studies have ever concentrated on the quality of information system operation management service. This study, moreover, is to define the quality of service related with customer satisfaction from customer's viewpoint, measuring effects on customer satisfaction. The quality of outsourcing service on information system in this study is a great help to companies who are offering information outsourcing service, and company's managers and staffs who outsourcedto specialized company.

  • This study is for the purpose of understanding User Satisfaction of Accounting Information System more closely by means of perceiving relations between Internal Controls and Quality. That is, this study is to assess Internal Controls and Quality and to connect those with User Satisfaction. This thesis is for the substantial study on whether Information Quality, System Quality, and Service Quality influenced by Internal Controls of Accounting Information System have an effect on User Satisfaction, when Internal Controls of Accounting Information System is good, The following hypothesis was made to achieve this purpose. First, Internal Controls will have an positive influence on Quality. Second, Qualify will positively affect User Satisfaction. Third, Internal Controls will positively Influence User Satisfaction. Fourth, Internal Controls will have a positive effect on User Satisfaction through Quality For the survey sample, this study gathered data on someone engaged in companies or organizations which have computer offices, and groups were differentiated between general staff and someone in charge of the computer office, and each group had different questions. In general, 622 of questions were distributed and 200 of the final valid samples were used for the substantial analysis. As the result of the study, the relations between Internal Controls and Quality are statistically significant. The relations between Quality and User Satisfaction ire also statistically significant. But the relations between Internal Controls and User Satisfaction are not statistically significant. Path Analysis was implemented to analyze the hypothesis on whether Internal Controls have an influence on User Satisfaction through Quality. When the result of analysis with Lisrel 8.5 was examined, index numbers(GFI, AGFI, RMR) representing the suitability of the model were enough to be taken and it is showed that there is the suitability of the model. Internal Controls of Accounting Information System can't have an influence on User Satisfaction with Quality. As the above hypothesis was rejected, Through Path Analysis, this study examined the influence which relations between Internal Controls and Quality, factors of User Satisfaction, have on User Satisfaction, and is very meaningful in terms of the first trial. And on the point of time when there are little studies on the effect analyses between Internal Controls and Quality, this study would be the promoter for the future. The limitation on this study is to analyze only mutual effects between factors by choosing Internal Controls, Quality, and User Satisfaction as survey variables. The study which measure items with precision which are related to each variable and understand measurement factors clearly should be implemented.

  • Purpose. The purpose of this study is to investigate the success model related to the hospital information system accomplishment. It is important to examine the success model of the hospital information system and to analyze the factors affecting the job satisfaction accomplishment. Methods. The method of this study is to 150 copies of the entire survey data were distributed and 135 copies were collected, showing a collection rate of 90%. In order to ensure the reliability of the questionnaire items, Cronbach's Alpha was used to test reliability, and exploratory factor analysis was conducted to determine the convergence of various items. In order to grasp the convergence of various items, exploratory factor analysis was performed. The results of exploratory factor analysis were used to analyze the correlations between variables that were proven to have a single dimensionality before calculating factor loadings and regression analysis by Orthogonal Rotation by Varimax method Results. The results of this study, first, the system quality of the hospital information system has a statistically significant effect on user satisfaction. Second, the information quality of hospital information system is statistically significant for user satisfaction, indicating that information quality improves user satisfaction. Third, service quality of hospital information system was statistically significant in user satisfaction. Finally, the higher the satisfaction of the users who use the hospital information system, the higher the accomplishment of the organization Conclusions. This study is based on the successful model of D & M information system. In addition, the hospital information system, the user satisfaction, and the organizational accomplishment in connection with it can be found significant.
