This paper presents a tool that enables non-technical (naive) end-users to use free-form queries in exploring distributed relational databases with simple and direct technique, in a fashion similar to using search engines to search text files on the web. This allows web designers and database developers to publish their databases for web browsers exploring. The proposed approach can be used for both Internet and Intranet application areas. Our approach depends on identifying first databases that are most likely to provide useful results to the raised query, and then search only the identified databases. In our work, we developed and extended an estimation technique to assess the usefulness measure of each database. Our technique has been borrowed from the similar techniques used for information retrieval (IR), mainly for text and document databases;it supports working smoothly with the structured information stored in relational databases. Such a usefulness measure enables nave users to make decisions about databases to search and in what order.

We present a decision tree evaluation method integrated with a common framework for analyzing multi-attribute decisions under risk, where information is numerically imprecise. The approach extends the use of additive and multiplicative utility functions for supporting evaluation of imprecise statements, relaxing requirements for precise estimates of decision parameters. Information is modeled in convex sets of utility and probability measures restricted by closed intervals. Evaluation is done relative to a set of rules, generalizing the concept of admissibility, computationally handled through optimization of aggregated utility functions. Pros and cons of two approaches, and tradeoffs in selecting a utility function, are discussed.

The telemedicine systems for the decision of patient transfer, and the direction of patient treatment through remote consultation are necessarily required for better patient care in emergency situation. In this paper, the prototype emergency telemedicine system has been designed and implemented. The unified integration of multimedia components, including full-quality video, vital sign signals, radiological images and video conferencing in a single computer, provides an efficient means to investigate the accurate status of emergency patient at the remote location. The software implementation of needed functionality without any externally attached hardware CODEC units enables the compact design with low cost, and ease of operation at the emergency room. Experimental tests at the local networks analyze the technical aspects of implemented systems, and optimize the parameters subjectively to run telemedicine systems with affordable error. Inter-hospital experiments demonstrate the possibility to be effectively used at emergency situation.
