Computer and communication technologies have been progressing rapidly in these few years, which speeds up the electronic medical record (EMR) development and increases the requirement of electronic data interchange (EDI) among healthcare organizations. Although the health data exchange standard of Health Level 7 (HL7) has been around more than a decade, hospitals have been applying the standard only recently, with little experience. Because the quality of the hospital information system (HIS) varies in each institution, it is difficult to judge whether the transmitted data match with the standards completely. If there is any mistake in the exchanged data, it will cause problems to the whole information system as well as to patient records. It is necessary to have a validation mechanism to verify the integrity of the data before data exchange. The authors introduce the method of implementing a Web based validation system providing HL7 message test services. This method may accept and parse HL7 messages and warn of errors in segments, sequences, required fields, field length, components, data types and valid values. The system is ready for HL7 version 2.3. Besides benefiting health care organizations, the system may also provide assistance to students who major in medical informatics.

This paper presents an object oriented framework for task scheduling. This framework can be used in domains such as process-centred software engineering environments, workflow management systems or project management systems. The framework was conceived based on both current methods for the development of frameworks and an existing architectural pattern for process managers. A prototype of the framework was developed using the Java language. The lessons learnt show the experience of extracting a framework from well-known applications that can be reused in practical domains. Thus, this work contributes not only in the production of a framework but also giving insights in the application of novel techniques to the development of frameworks.

To ask whether and to what extent there is an obligation to treat illegal immigrants implies—just in the asking—that any duty to treat an illegal resident is different from or lesser than the duty to treat a citizen. What could be the reason for thinking that morality affords fewer benefits or rights to illegal residents?

This article, in two parts, presents information on the evaluation of Web sites in general and the choice of women's health Web sites in particular. A review of studies and tools for Web site evaluation is followed by a core list of women's health Web sites, from the perspective of the academic health sciences library. [ABSTRACT FROM PUBLISHER]

A Disease Management System (DMS) refers to an integrated healthcare delivery system that provides patient centered care throughout the course of the disease independent of delivery site. A fundamental barrier for the development, implementation and monitoring of a DMS is lack of an appreciation by care providers of the complexity of these systems, and what is required for their maintenance. Foremost in the development of these systems is the presence of information systems that attempt to deal with the temporal, spatial and information needs of the DMS. Purpose: The Zachman Framework for Information Systems Architecture is used in many industries in the development of information systems. Its choice is based on the recognition of a need for a methodology in the conceptualization and modeling of complex information systems. This paper provides a brief overview of the Zachman Framework and its potential application in DMS development. In particular it will be the focus on the peed for 'perspective' clarification as the first step in the development of such complex systems. Results: This paper reviews DMS and their potential information needs. The clarification of 'perspectives' provides a method toward team building and unification of purpose by decreasing conflict and recognizing the unique contributions that each perspective holder makes.

This paper reports a model of document retrieval for the Portuguese language, developed from a Miyamoto document-retrieval model. The Miyamoto model is based upon semantic similarity detection of descriptors by co-occurrences. The proposed model may be considered an extension of the Miyamoto model because it considers lexical similarities and expression similarities. Hence, descriptors and queries are expressions, i.e. series of words and connectors (prepositions, etc.). The similarity between words is based on the comparison between possible radicals for the detection of words with identical or similar meanings. The expression similarity is determined by comparing words and connectors using an adaptation of a Bruza and van der Weide (1991) model. The proposed Miyamoto model extension considers both: the determination of a fuzzy thesaurus by a fuzzy index, achieved through lexical descriptor similarities; and the possibility of a non-controlled vocabulary use by the determination of similarities between document descriptors and query expressions. A sample document base was created for the comparison between the models. The results show the usefulness of the proposed model for document retrieval in the Portuguese language.

The objective of this research was to identify the relationships between the selection process and the perceived impacts of information technology on the physician's practice. A telephone survey was conducted with office representatives of 407 physician practices in Oregon. The descriptive results are presented in this summary paper. Relationships were identified between the selection process and the perceived impacts of the software on the practice. These relationships are not directly presented in this paper but are summarized and recommendations are made to physician practices for selecting software.
To date, few articles have documented the selection process and the resulting impact of the information technology on the health care organization. Information technology (IT) for this study is defined as: computer so...

To date, few articles have documented the selection process and the resulting impact of the information technology on the health care organization. Information technology (IT) for this study is defined as: computer software used to store, transport and communicate information. This study was designed to gain understanding on how physicians and office staff select software and what the perceptions are of the software after implementation. The primary objective of this research was to identify relationships (if any) between the selection process and the perceived impacts of the software on the physician's practice.
