The distribution of cases and controls according to VDT
use, length of use, and VDT
-related activity is presented in Table 2.
Independent samples t-tests performed to compare z-scores for thresholds obtained in pain sites and thresholds obtained in nonpain sites did not reveal any significant group differences for any of the stimulus modalities tested (MDT, VDT
, ATDT, ATPT).
In this study, an attempt was made to model VDT
based on the topographical attributes and using a MLE The input layer comprises processing elements that represent each of the explanatory topographical variables, and the output layer contains a single neuron that gives the value of the dependent variable to be predicted, i.
This led to a situation in which the Office of Management and Budget contested the validity of an epidemiological study about the reproductive problems of female VDT
workers conducted by the National Institute for Occupational Safety and Health (NIOSH) about nonionizing radiation.
For example, VDT
workers are paced by the processing speed of the VDT
; they have to input commands and continuously react to the information consequently displayed on the screen, forcing them to engage in very intense and stressful work as the processing speed of the VDT
The basic premise of the VDT
model is that organizations are fundamentally information-processing structures.
Stress has potential to affect human health when coupled with VDT
It may be necessary to make or buy a hood for the VDT
to shield it from reflection.
Reports of CTD, including carpel tunnel syndrome among VDT
users, have been cited by other researchers also (NIOSH, 1992; Pot et al.
Several Bells have launched investments on VDT
networks that Will end up costing tens of billions of dollars (since they have to lay their own lines), but no commercially viable system is yet in place.
In 1978, VDT
entered on a marketing try-out of the push-block CVT system with 200 Fiat Ritmos/Stradas (1.
A similar comparison reported eyestrain three times as often among VDT
