Rapid progress in electronization of hospital information gives an opportunity to realize evidence-based hospital management and services. This paper proposes a clustering-based data mining approach to temporal data in hospital information. The process consists of repetitions of clustering for grouping records and decision tree inducion for feature selection. It will terminate if the clustering results are converged. We evaluated this method to data on order history stored in hospital information system. The results show that the reuse of stored data will give a powerful tool for hospital management and lead to improvement of hospital services.

Research advances in network traffic forecasting are continually emerging in the literature. Although the progress in this field, the quality control of traffic forecasts is commonly neglected in previous works. In this paper we analyze the performance of CuSum, Shewhart, and EWMA control charts applied to the residuals of forecasting models fitted to selected traffic samples obtained from real IP networks. Based on numerical and graphical analyses, we verify that CuSum and Shewhart control charts perform worse than EWMA, since they report false alarms for several forecasting processes considered under control. Differently, the EWMA control chart shows efficacy to monitor the different types of studied forecast residuals. Finally, we present a sensitive analysis of the EWMA model with respect to the lambda parameter in order to evaluate its flexibility on different traffic scenarios.
Geometric problems are usually solved by algebraic methods, which narrows the capacity of geometry. We represent a preliminary framework for geometric basis computing pattern. The pattern is based on He's theory a...
