PURPOSE Computerized static stabilometry is a clinical test in neurologic and muscular diseases to assess postural stability or body sway in a quantitative manner. The purpose of this study was to examine whether postural stability would change in the process of the prism adaptation test in patients with intermittent and constant exotropia. METHODS Postural stability was measured before the p...

BACKGROUND The Pictorial Representation of Illness and Self Measure (PRISM) has been introduced as a visual measure of suffering. We explored the validity of a revised version, the PRISM-RII, in diabetes patients as part of the annual review. METHODS Participants were 308 adult outpatients with either type 1 or type 2 diabetes. MEASURES (1) the PRISM-RII, yielding Self-Illness Separation (S...

AIMS To assess the reliability of mortality risk assessment using the Paediatric Risk of Mortality (PRISM) score and the Paediatric Index of Mortality (PIM) in daily practice. METHODS Twenty seven physicians from eight tertiary paediatric intensive care units (PICUs) were asked to assess the severity of illness of 10 representative patients using the PRISM and PIM scores. Physicians were divi...

BACKGROUND Chronic urticaria severely affects quality of life. To date, no gold standard has been established to measure the burden of suffering, which often correlates poorly with the skin symptoms observed in patients with chronic urticaria. OBJECTIVE To investigate the effect of psychological factors on the course of urticaria. METHODS Health-related quality of life was assessed in 95 pa...

The value of socializing in collocated multiplayer video games should not be underestimated. Inter-player interactions such as joking, bantering and strategizing all contribute towards creating rewarding and memorable gameplay experiences for the players involved. In this paper, we introduce Prism Squad: GO!, a cooperative, three-player video game which is designed to encourage and cultivate th...

PURPOSE To investigate the relationship between muscular asthenopia and eccentric ablation after photorefractive keratectomy (PRK). METHODS Sixteen eyes of eight myopic patients whose muscular asthenopia was corrected by subjectively accepted spectacle prism after PRK, with visual acuity better than 0.8, were followed for 6 to 14 months. On the basis of preoperative and post-operative data an...

The Prism family of algorithms induces modular classification rules which, in contrast to decision tree induction algorithms, do not necessarily fit together into a decision tree structure. Classifiers induced by Prism algorithms achieve a comparable accuracy compared with decision trees and in some cases even outperform decision trees. Both kinds of algorithms tend to overfit on large and nois...

Ensemble learning techniques generate multiple classifiers, so called base classifiers, whose combined classification results are used in order to increase the overall classification accuracy. In most ensemble classifiers the base classifiers are based on the Top Down Induction of Decision Trees (TDIDT) approach. However, an alternative approach for the induction of rule based classifiers is th...
