The Medical Text Indexer (MTI) is a program for producing MeSH indexing recommendations. It is the major product of NLM's Indexing Initiative and has been used in both semi-automated and fully automated indexing environments at the Library since mid 2002. We report here on an experiment conducted with MEDLINE indexers to evaluate MTI's performance and to generate ideas for its improvement as a tool for user-assisted indexing. We also discuss some filtering techniques developed to improve MTI's accuracy for use primarily in automatically producing the indexing for several abstracts collections.

Comparative StudyIntroduction of an operating room information management system improved overall operating room efficiency.
Operating Room (OR) information systems should manage the OR time, assigned to every surgeon, thereby minimizing the sum of costs of unused OR time and minimizing the costs of elective cases performed outside normal allocated OR time (excess OR-time). The aim of this paper is to illustrate how the introduction of an OR information system influenced daily OR activity performance. Since January 2001, we introduced an OR information system with a visual, airport-like, screen as central part, displaying all scheduled OR activity linked in real-time activity with all OR theatres. ⋯ In conclusion, in 2001 we recorded an increase in total OR activity for elective abdominal surgery by 7% in number of procedures and by 8% in total duration. However, in 2001 we recorded a decrease in excess time by 16% (123 h 04 min vs 147 h 20 min), which was for a large part due to a 23% decrease in unused OR time in 2001 compared to 2000 (35 h 21min vs 46 h 45 min). Therefore, the introduction of an OR information system, with a real-time visual display of ongoing OR activity, resulted in a increased performance of OR activity, with more OR procedures performed despite less excess time and less extra costs.

The use of web-based education has increased significantly. As a result there is a need to focus on methods, employed to evaluate teaching and learning outcomes, when technology is used to enhance learning. This chapter provides an overview of what, how, and why to assess, test and measure learning. ⋯ Evaluation generates information which can be used for different purposes e.g. planning, implementing and guiding teaching and learning processes timely and for the future as well. Based on experiences of teaching health informatics, an evaluation model for web-based courses is described. The risks of dishonesty and misbehavior related to web-based education are recognized.

This paper presents the results of an investigation into the design of low cost, four degree of freedom force/torque resolvers for use in compact haptic devices for surgical training. Two designs using piezo-resistive sensors are described and one using strain gauges. The advantages and disadvantages of each approach are stated and conclusions presented.

Edutainment tools for initial education of type-1 diabetes mellitus: initial diabetes education with fun.
Appropriate initial education for type-1 diabetes mellitus patients is important to prevent late complications. However, type-1 diabetic children have not appreciated traditional learning methods since they rarely contain the elements of fun and interactivity. In this study, we developed, implemented and evaluated a preliminary version of edutainment tools for initial education for type-1 diabetic children. ⋯ Our edutainment systems were accepted as attractive learning tools for type-1 diabetic children who need initial education.
