Light-on test workers are similar to VDT workers in that they need to look at screens during their work, and therefore it is not surprising that the two groups of workers share similar eye symptoms.
However, whereas light-on test workers work in clean rooms with low illumination, VDT workers do not necessarily work in such environments.
Many workers complained about eye discomfort, and therefore we conducted a study to evaluate the tear secretion function of light-on test workers of a TFT-LCD company.
All the remaining 319 light-on test workers agreed to participate in the study.
In addition, all the light-on test workers in our study worked for 12 hours in each shift, which might also contribute to the development of the eye symptoms.
During the study period, a total of 371 light-on test workers received the health examination at the clinic of the park, and 52 of them were excluded due to having ophthalmic diseases and other systemic diseases that may affect ophthalmic function.
The results indicate that there are no statistically significant relationships between external illuminance and lighting use patterns, but there is a clear time of day effects (i.e. a strong tendency of turning on lighting on worker's first arrival in the morning).
The fishing boat was spotted at first light on Monday by workers for contractors Modec, who were on a tanker servicing an oil rig about 78 nautical miles, or 150km, offshore from Dampier, which is about 1,500km north of Perth.
Mukpo has worked at Human Rights Watch and spent two years in Liberia working as a researcher for the Sustainable Development Institute, a non-profit shining light on concerns of workers in mining camps outside Monrovia.
Furthermore, the identification of factors that predict chronic disability may also shed light on why some workers develop chronic disability, and thus guide the development of intervention strategies that may prevent this process from occurring.
