Florida physicians' guide to on-line information and the Internet.
The combination of new computing technology with progress in data communications over wide geographic areas offers computer users the opportunity to publish information to each other rapidly across wide geographic expanses. The concept of networking computers to gain access to the most recent and widest range of available information is consistent with the aims and methods of quality health care. The Internet is the ultimate extension to the computer network concept- an unlimited link of digital servers and users world-wide, united by common protocols for purposes of information exchange, self-policed and without central controls. Although the concept is attractive, on-line servers and the Internet are sophisticated information tools whose most effective use requires that users be oriented to basic concepts and conventions. This article summarizes the basic conventions in computer networking and data security; the differences in concept and use between bulletin board systems (BBSes), online systems, and the Internet for information access; the various classes of Internet information resources and their uses; the basic use of search engines to expedite information retrieval in the Internet; and offers practical advice in choosing methods of Internet access.

Increasing the effectiveness and efficiency of academic advising through computerization.
Academic advising is an essential part of any university degree program and becomes especially important in programs where there is competitive and limited admission to professional courses. This requires that academic advisors have ready access to student scholastic and demographic data for counseling and statistical purposes. The use of computers in creating a database for student records has become routine in most universities and colleges. Computerization of these records through the registration process creates a university database with the potential for many different applications. This article describes the development of a computer software program for a baccalaureate science of nursing program that makes use of a university's database to provide the foundation of a computer software program used in the nursing academic advising office. Identifying the special needs and requirements of the nursing advising program and developing a close working relationship with the computer programmer were essential in the development and implementation process. The result was an increase in the effectiveness and efficiency of the advising process, better record keeping, and better use of available student data for statistical purposes.

Technology assessment. A framework for generating questions useful in evaluating nursing information systems.
Nursing information systems are computer systems that enable nurses to collect, manipulate, store, retrieve, display, and communicate data to administer nursing services and resources, manage nursing practice to improve patient care, and advance nursing knowledge. Selection and implementation of a nursing information system require a clear vision of the need for the system, careful planning, and astute forward thinking. Technology assessment provides a framework for generating pragmatic questions that can be used in systematically evaluating nursing information systems. This article provides a brief overview of nursing information systems, explains the technology assessment framework, and gives examples of questions useful in evaluating a nursing information system.

Interactive videodisc instruction is an alternative method for learning and performing a critical nursing skill.
A study was conducted to compare the effectiveness of interactive videodisc instruction (IVDI) with the traditional lecture/demonstration as an alternative method for learning and performing a critical nursing skill. Students were assigned randomly to a treatment group that worked in small groups to complete the IVDI on intravenous therapy skills and a control group receiving the same content in a classroom lecture/demonstration format. After the instruction, each subject performed a re-demonstration of the learned skills using specific guidelines. Results revealed that although the IVDI group scored higher on the overall re-demonstration, there was no significant difference in the ability of the two groups to effectively perform this critical nursing skill. These findings support the use of IVDI as an alternative self-paced, independent study method for learning psychomotor skills and are consistent with previous studies, which indicate that working in small groups on the computer has a positive effect on self-efficacy and achievement.

The VideoToolbox software for visual psychophysics: transforming numbers into movies.
The VideoToolbox is a free collection of two hundred C subroutines for Macintosh computers that calibrates and controls the computer-display interface to create accurately specified visual stimuli. High-level platform-independent languages like MATLAB are best for creating the numbers that describe the desired images. Low-level, computer-specific VideoToolbox routines control the hardware that transforms those numbers into a movie. Transcending the particular computer and language, we discuss the nature of the computer-display interface, and how to calibrate and control it.

Computed tomographic colography and virtual colonoscopy.
CT colography (CTC) is a powerful new approach to imaging the colorectum and a promising screening tool for the detection of colorectal neoplasia. From data generated by a helical CT scan, CTC uses virtual reality technology to produce highly discriminant two- and three-dimensional images that permit a thorough and minimally invasive evaluation of the entire colorectum. A dynamic CTC display technique from the endoluminal perspective, called cf2virtual colonoscopy,cf1 simulates colonoscopy by "flying" through the three-dimensional colon image. CTC offers potential advantages in diagnostic performance, safety, and patient acceptance over current screening approaches. Although early data suggest excellent colorectal polyp detection rates, this nascent technology will require rigorous clinical investigation and further refinements to assess adequately its place in the endoscopist's armamentarium.

Virtual reality exposure therapy.
It has been proposed that virtual reality (VR) exposure may be an alternative to standard in vivo exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment. Virtual reality exposure is potentially an efficient and cost-effective treatment of anxiety disorders. VR exposure therapy reduced the fear of heights in the first controlled study of virtual reality in treatment of a psychiatric disorder. A case study supported the efficacy of VR exposure therapy for the fear of flying. The potential for virtual reality exposure treatment for these and other disorders is explored, and therapeutic issues surrounding the delivery of VR exposure are discussed.

Continuing medical education on the World Wide Web (WWW). Interactive pathology case studies on the Internet.
OBJECTIVE: To present interactive online continuing medical education (CME) over the World Wide Web as a more efficient alternative to traditional modes of CME delivery. DESIGN: A departmental Web site available to those with access to the Internet. SETTING: A tertiary-care teaching hospital in the United States. RESULTS: Comprehensive case studies have been developed and are complete with images, text, and questions, including explanations for correct and incorrect responses. The images are linked to pertinent text to maximize their educational value. The cases are easily accessible, user friendly, and fully referenced. The system became operational in January 1996, and the first CME certificate was awarded to a participant shortly thereafter. CONCLUSIONS: Continuing medical education over the World Wide Web is an efficient means of delivering CME to the community at large; it allows participating physicians the latitude to obtain convenient CME credit at their leisure, in contrast to the regimented experience of formal CME conferences or symposiums. The interactive format of the CME cases allows the participant to submit immediate comments or criticism to case authors and receive instant feedback on their own performance, features unavailable in comparable educational software packages. The dynamic environment of the World Wide Web lends itself to the production and dissemination of such flexible forms of CME for the physician and will continue to expand in this capacity into the foreseeable future.

Dysarthric speech: a comparison of computerized speech recognition and listener intelligibility.
The purpose of this study was to identify and compare the recognition of dysarthric speech by a computerized voice recognition (VR) system and non-hearing-impaired adult listeners. Intelligibility "functions" were obtained for six dysarthric speakers who varied in severity and six age- and gender-matched controls. Speakers produced 70-item word lists over 5 sessions. VR using the IBM VoiceType and perceptual judgment scores were obtained and functions plotted by session. Data indicate that computerized recognition of both dysarthric and nonimpaired speech was characterized by initially steep increases in correct recognition with more gradual increases noted during the second through fifth sessions. Perceptual recognition by non-hearing-impaired adults indicates generally stable intelligibility scores over time. Severity of dysarthria did appear to influence recognition of target stimuli. Implications of these data to the application of computerized VR technology are presented.
