The granite industry in Cornwall and Devon is briefly described, especially the production of dust in dressing the stone. In 1951, 210 granite masons were examined (about 84% of the total at that time) and 37 (17 6%) showed silicosis. These men were followed up for 10 years. No silicosis was seen in men with less than 15 years' exposure, but after this time the risk increased to 11 out of 14 in...

Estimates of peak spinal compression in manual materials handling were compared between a state-of-the-art laboratory technique and a method applicable at the worksite. Nine experienced masons performed seven simulated tasks in a mock-up in the laboratory and nine matched masons were studied during actual performance of the same tasks at the worksite. From kinematic and kinetic data obtained in...

Manual material handling (MMH) is unavoidable because of the nature of jobs or tasks as and man-machine interfaces in a construction worksystem. Data were collected from six strata of workers viz., masons, mason helpers, carpenters, welders, gas cutters and ground-level helpers (259 out of 700 workers) from a construction site of a steel plant located in India to analyze different types of occu...

Choiceboards are Web-based systems that allow consumers to customize their orders. The study investigated factors that affect consumers’ intention to use choiceboards. The research is based on Masons’ theory and DeLone and McLean’s model of information system use. It was found that intention to use is affected by overall satisfaction. In turn, these two factors are positively impacted by factor...

Occupational health is a neglected and heedless domain within the healthcare system in Pakistan. Despite the formulation of a National Action Plan for Prevention and Control of Non-Communicable Diseases and Health Promotion in Pakistan in 2004,1 little has been achieved and much needs to be improved.2 Foremost is the need for legislation to enforce work-safety regulations and raise the status a...

This is a book by an American author, Professor N. C. D. Lewis, of Columbia University. It is of a quite unusual kind and is the result of the author's attempt to collect the findings of research work done into the condition during the last fifteen years. Its publication in America was largely made possible by the beneficience of the Scottish Rite Masons. In the prefact it is suggested that it ...

BACKGROUND Non-melanoma skin cancer (NMSC) is the most frequent tumour among Caucasian populations worldwide. Among the risk factors associated with this tumour, there are host-related factors and several environmental agents. A greater likelihood of high exposure to physical agents (with the exception of solar radiation) and chemical agents depends on the work setting. Our objective is to eval...
