The luminaire with the lowest lumen output (a 1x4 with 1999 lm) has a mean luminous intensity of 329 cd at 55[degree], which is greater than RP-1's upper limit of 300 cd (see Table 1) for VDT

To gain further information, we considered data from a case-control study on the association between VDT
use in pregnancy and the risk of SGA birth.
Therefore, a measurement taken during any trial on which the subject reported feeling a sensation that was qualitatively different from the specific modality being tested (e.g., reporting an "electrical" pain sensation during VDT
or reporting only a "muscle contraction" sensation during thermal testing) was eliminated from the present analyses.
These two normally antagonistic parts of the business community worked in concert against any attempts to regulate VDT
Kanaya (1990) stated that one of the causes of VDT-related complaints was the high density of office work created by the introduction of the VDT
. 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
Measured diagonally from one comer of the screen to another, VDTs
commonly come in 14-, 15-, 17-, and 20inch sizes.
