Although learning through a computer interface has become increasingly common, little is known about how to best structure video-recorded lectures to optimize learning. In 2 experiments, we examine changes in focused attention and the ability for students to integrate knowledge learned during a 40-min video-recorded lecture. In Experiment 1, we demonstrate that interpolating a lecture with memo...

OBJECTIVE To determine the extent of agreement between clinical information recorded on surgery computers of selected general practitioners and similar information in manual records of letters received from hospital consultants and kept in the general practitioners' files. DESIGN Hospital consultants' letters in the manual records of selected general practitioners were photocopied and the con...

BACKGROUND Anesthesia information management systems allow automatic recording of physiologic and anesthetic data. The authors investigated the prevalence of such data modification in an academic medical center. METHODS The authors queried their anesthesia information management system database of anesthetics performed in 2006 and tabulated the counts of data points for automatically recorded...

One hundred and fifty hospital outpatients were questioned about their bowel habits and then asked to record these in diary booklets for two weeks. Overall, recalled and recorded figures for frequency of defecation agreed fairly closely, but in 16% of patients there was a discrepancy of three or more bowel actions per week. This was usually an exaggeration of the difference from the norm of one...

The Interlab Project is a university-industry joint project recently funded by the Italian government as part of the improvement of the Italian research infrastructure; among its short-term goals are the implementation of data banks of biomedical interest and the spread of informatic tools for biomedical research. Results of both long-term assays of carcinogenicity in rodents and short-term in ...

The major activity of Business Intelligence (BI) is to dig out the various trends and patterns from variety of authentic sources that helps the managers to take appropriate decision in framing the policies for business plans accordingly. Surveys are considered to be an essential part of BI. Surveys conducted amongst different or same groups by different team may yield conflicting reports. Moreo...

OBJECTIVE Action potentials and local field potentials (LFPs) recorded in primary motor cortex contain information about the direction of movement. LFPs are assumed to be more robust to signal instabilities than action potentials, which makes LFPs, along with action potentials, a promising signal source for brain-computer interface applications. Still, relatively little research has directly co...

When functional neuromuscular stimulation (FNS) is used to restore the use of paralyzed limbs after a spinal cord injury or stroke, it may be possible to control the stimulation using feedback information relayed by natural sensors in the skin. In this study we tested the hypothesis that the force applied on glabrous skin can be extracted from the electroneurographic (ENG) signal recorded from ...
