A new algorithm for use in computer identification.

On 9 May 1987, a Soviet-made IL-62M Polish airliner, LOT Flight 5055, crashed, exploded, and burned, killing the crew and 183 passengers. A forensic science team from the Armed Forces Institute of Pathology, comprised of 6 dental officers, 3 forensic pathologists, and 3 medical photographers, worked in concert with the Polish forensic science team. The small number of antemortem records and the extreme fragmentation of the remains presented a new scenario for computer use. Typically, the Computer-Assisted Postmortem Identification (CAPMI) software is used to compare remains against an antemortem database. Results are listed by the number of tooth-to-tooth matches based on restorative or other characteristics or both. The Polish disaster confounded this approach to some degree, however, and suggested a reconsideration of the theory on which the sort is made, that is, that the cases with maximum number of matches to preexisting dental records would be the most likely identification (ID) match. A hypothesis was constructed that, if searches were accomplished for fragments with a minimum number of mismatches, the correct matches would appear higher in the rank order. Six antemortem records (that had all dental information) were sorted against one hundred and twelve postmortem fragmented records. The resulting report was reordered so that records were listed by minimum number of mismatches. There was significant improvement in rank placement for all of the records. Thus it was accepted that in the situation of highly fragmented remains a different sorting based on the number of mismatches is indicated. Programming changes to make this option available have been implemented in the new version of CAPMI.

Virtual reality in behavioral neuroscience and beyond.

Virtual reality (VR) has finally come of age for serious applications in the behavioral neurosciences. After capturing the public imagination a decade ago, enthusiasm for VR flagged due to hardware limitations, an absent commercial market and manufacturers who dropped the mass-market products that normally drive technological development. Recently, however, improvements in computer speed, quality of head-mounted displays and wide-area tracking systems have made VR attractive for both research and real-world applications in neuroscience, cognitive science and psychology. New and exciting applications for VR have emerged in research, training, rehabilitation, teleoperation, virtual archeology and tele-immersion.

Calibration of a system for the computer-assisted operation of a small animal inhalation facility.

The initialization of chambers in the computer-assisted inhalation facility at the National Institute of Environmental Health Sciences (1) includes a series of operations that we call "characterization." Characterization consists of two parts, the first of which is one of the topics of this report. In the first part of the characterization the mathematical relationship between the concentration of the chemical of interest and the output of the analyzer is approximated. This amounts to establishing a standard against which subsequent, daily calibrations can be compared. The second part of the characterization represents a wholly automatic operation in which certain dynamic characteristics of the system are quantified. A daily calibration is performed at the beginning of each day of chamber operation after the system has been characterized. The daily calibration data are checked against the characterization standard. The conversion equation for the daily operation of the chamber is derived from the daily calibration data combined with the characterization data. An equation that converts the output of the analyzer to units of concentration of the chemical of interest is at the heart of the computer-assisted monitoring and control system for our inhalation facility. The equation is derived from a calibration procedure that is conducted prior to starting each day's chamber operation. Quality control requires that, in addition to having a daily calibration of the system, a standard of reference be available against which each day's calibration data can be checked. This practice provides protection against the introduction of spurious calibration data on a daily basis, as well as providing a means for the detection of longer term drift.(ABSTRACT TRUNCATED AT 250 WORDS)

Teaching psychology as a laboratory science in the age of the Internet.

For over 30 years, psychologists have relied on computers to teach experimental psychology. With the advent of experiment generators, students can create well-designed experiments and can test sophisticated hypotheses from the start of their undergraduate training. Characteristics of new Net-based experiment generators are discussed and compared with traditional stand-alone generators. A call is made to formally evaluate the instructional effectiveness of the wide range of experiment generators now available. Specifically, software should be evaluated in terms of known learning outcomes, using appropriate control groups. The many inherent differences between any two software programs should be made clear. The teacher's instructional method should be fully described and held constant between comparisons. Finally, the often complex interaction between the teacher's instructional method and the pedagogical details of the software must be considered.

Putting the human body in a computer.

Over the past 20 years, computer simulation has become an invaluable third leg of research in the physical sciences, adding to the traditional tools of theoretical studies and experimental observation. Simulation can give far more accurate pictures than can be provided by theoretical analysis, and show processes that are difficult to observe in detail. Recently, this invaluable tool has been successfully applied to medicine, where the systems tend to be more complex, requiring more computer power. The results are likely to be as far reaching as they have been in physics and chemistry.

Brain-machine and brain-computer interfaces.

The idea of connecting the human brain to a computer or machine directly is not novel and its potential has been explored in science fiction. With the rapid advances in the areas of information technology, miniaturization and neurosciences there has been a surge of interest in turning fiction into reality. In this paper the authors review the current state-of-the-art of brain-computer and brain-machine interfaces including neuroprostheses. The general principles and requirements to produce a successful connection between human and artificial intelligence are outlined and the authors' preliminary experience with a prototype brain-computer interface is reported.

Collecting, communicating and using information: the educational issues. A report from the Royal College of Physicians Committee on Medical Information Technology.

Few of the major advances in information science and technology have yet been successfully introduced in health care. Their implementation could improve both quality of care and the working environment of clinicians, but this will not be achieved by investing in hardware and software alone. Investment in education is also required.

Computer-assisted instruction in parasitology: a cross-over design.

We report here the results of the study using CAI compared to the hard copy for study of lessons in parasitology. We evaluated the CAI compared to hard copy lessons in 60 students, attending the third-year parasitology course at Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand. The students were randomly divided into two groups (30 each). The lessons tested were Ascaris lumbricoides and Enterobius vermicularis, which were prepared as CAI and hard copy form. Using a cross-over design, the first group was provided CAI form on the topic of A. lumbricoides, then switched to hard copy form on the topic of E. vermicularis. The second group was provided hard copy form on the topic of A. lumbricoides, then switched to CAI form on the topic of E. vermicularis. After 30 minute reading, the 10-multiple choice question test was provided for each topic. There was no significant difference of the scores between 2 groups. The most students (91.67%) had more satisfaction when using CAI compared to hard copy in terms of easy to use, convenient to use, less time consuming, more understandable, more attractive to read, and less stress for study. There were 32.8% students complaining that reading hard copy was boring. Other comments were stress when reading (2%), more difficult (17.2%) and more time needed to search specific information (17.2%), and wasting papers (17.2%). However 58.6% still complained problems when using CAL. About 25% had physical discomfort (e.g. Headache, eye pain), and 25% had difficulty to access to use CAI (e.g. no computers available, problems with computer or network error). We suggested that instructors should create and improve CAI lessons in biomedical sciences both in quantity and quality (e.g. content with details, pictures, narrations).

Computer-aided tissue engineering of a human vertebral body.

Tissue engineering is developing into a less speculative science involving the careful interplay of numerous design parameters and multidisciplinary professionals. Problem solving abilities and state of the art research tools are required to develop solutions for a wide variety of clinical issues. One area of particular interest is orthopedic biomechanics, a field that is responsible for the treatment of over 700,000 vertebral fractures in the United States alone last year. Engineers are currently lacking the technology and knowledge required to govern the subsistence of cells in vivo, let alone the knowledge to create a functional tissue replacement for a whole organ. Despite this, advances in computer-aided tissue engineering are continually growing. Using a combinatory approach to scaffold design, patient-specific implants may be constructed. Computer-aided design, optimization of geometry using voxel finite element models or other optimization routines, creation of a library of architectures with specific material properties, rapid prototyping, and determination of a defect site using imaging modalities highlight the current availability of design resources. This study proposes a novel methodology from start to finish which could, in the future, be used to design a tissue-engineered construct for the replacement of an entire vertebral body.

Emergency protocols in prehospital emergency medicine in Slovenia.

Emergency medicine is a branch of medicine in which prompt and accurate information is of crucial importance, because a patient's survival and the final outcome of a treatment very often depends on it. Therefore the standardization of prehospital emergency service administration with uniform documentation, methods of annotation of technical data as well as uniform gathering and data analysis are necessary. Wanting to process a fair amount of data and specially to disburden personnel, a need for computer aided processing is evident. Application that was developed in strong collaboration with EMS project team and information science engineers definitely improves data quality. Firstly when team members, especially physicians, are constrained to fulfill paper forms and secondly when data are entered into the computer, because all inconsistencies are being reconsidered and corrected if necessary. The developed application also gave the opportunity to the emergency team for prompt and accurate information.
