The study of Relationship between Mental Work Load and Sleep Quality in Video Display Terminals Users

Background & objectives: One of the factors affecting the performance of video display terminal users is their mental work load. Since low sleep quality causes fault and decreased accuracy in work, this study aimed to evaluate the relationship between mental work load and sleep quality in video display terminals users. Methods: This descriptive cross-sectional study was performed on 191 video d...

Dosimetry of the Very Weak X-radiation Generated in Television Receivers and X-ray Diffraction Apparatus

With many kinds of apparatus in which electron tubes are operated at high voltages, the possiblepresence of very weak, soft Xvradiation, (i.e. Xradiation of low penetrating power) in the neighbourhood must be given due consideration. The question arises in such apparatus as X-ray diffraction equipment, formerly found only in research laboratories but now widely used industrially in inspection a...

Eye care when using video display terminals.

OBJECTIVE: To examine the scientific data in the literature regarding eye problems and possible damage during the use of computer video display terminals. DATA SOURCES: Medline and non-Medline literature search and personal experience. STUDY SELECTION: Studies that provided evidence-based information about eye damage and eye care during the use of video display terminals were selected. DATA EXT...

Predicting Flicker Thresholds for Video Display Terminals

This paper describes an analytical method for predicting whether a video display terminal will appear to flicker given the screen phosphor persistence, refresh frequencies, and other environmental factors such as ambient light level, the distance between the viewer and the display, etc. From the method, one can predict the maximum screen luminance and the minimum refresh frequency that will gen...
