Investigating users' requirements: computer-based anatomy learning modules for multiple user test beds.
User data and information about anatomy education were used to guide development of a learning environment that is efficient and effective. The research question focused on how to design instructional software suitable for the educational goals of different groups of users of the Visible Human data set. The ultimate goal of the study was to provide options for students and teachers to use different anatomy learning modules corresponding to key topics, for course work and professional training. ⋯ This study describes how users' requirements, associated with users' learning experiences, were systematically collected and analyzed and then transformed into guidelines informing the iterative design of multiple learning modules. Information about learning challenges and processes was gathered to define essential anatomy teaching strategies. A prototype instrument to design and polish the Visible Human user interface system is currently being developed using ideas and feedback from users.

The Arden Syntax was introduced more than 10 years ago, but it is still not in widespread use. One reason might be that for each particular architecture and information system, a different Arden Syntax compiler must be written as well as a program for the runtime execution of the medical logic modules (MLMs). The authors have designed and implemented an architecture that increases the portability of Arden Syntax rules, using the Java platform. ⋯ Also, the authors propose a convention to name signals that trigger other MLMs (called intermediate states) so that they remain unique to each institution. The authors implemented this architecture in their clinical system and in an XML-based medical record application that has been used experimentally in their urology and nephrology departments. The Tetrasys company that provided the medical record was able to incorporate their runtime without modifications, and typical MLM execution time was less than 1 sec.
