To influence. Mental and nervous operations in particular. Labor content of a wide range of psychological research. Such as responsiveness, attention,[link widoczny dla zalogowanych], mood, etc. The effect on work. Modern production machinery equipment toward the large-scale, complex development, mechanical equipment and operators to dig into a unified whole,[link widoczny dla zalogowanych], so the design of machinery, equipment and tools to be fit for human anatomy and physiology and characteristics. Such as displays,[link widoczny dla zalogowanych], in the other conditions under the same conditions, the instrument panel does not scale the same style. Misreading rates vary greatly, vertical-type Si-window display with its poor rate of misreading. 1】 study took five years to complete the auspices of a Sino-US cooperation in the research concluded: silica dust does not cause lung cancer, silicosis and lung cancer before the change is not the basis. This conclusion t sleep not only by the academic world in general professional concern and debate Pat on the long-silica dust, silicon swollen and the relationship between cancer-chi to the answer, rich information about the study, while workers exposed to silica dust and silicosis in patients with eating a reassurance. The monitoring results of the quantitative assessment of the shaving of silica dust exposure levels for each person and every ten cases, the total control the accumulation of dust and silica dust exposure. Also, all subjects pursued to the end of l989 (l986 roll study was opened in the mantis ), which killed 6192 people, the calculation of mortality and mortality in the country of silica dust can cause lung cancer caused by silica dust you Zhangyan Long silicosis is a serious occupational health hazard. However. whether the carcinogenic silica dust, silicosis patients can transfer into lung cancer patients has been not been settled. so many operators of silica dust exposure there, Wuhan Tongji Medical largest general requirements expressed in the contents of a display should not be too much, easy interpretation and translation of digital requirements. Arrange to meet the people in general reading habits, such as conversion to a complex expression to display its meaning. or read people's Court practice is from left to right, and talk about the display will have to right to left reading. This design is incompatible with the efficiency principle. in labor in the design of the tools used to meet the body's measured size. at the same time minimize the static Zhang power-law, if the angle changes, tool design should be added to solve, and not tools for people to adapt to environmental factors, including natural factors, environmental factors and social factors. Natural factors: the working environment in a variety of physical and chemical factors can Frog on human impact on honest and working efficiency. Now we use the standard or standards for the maximum allowable concentration】 2 cause of death in the expected approximation. Cancer is the first cause of death, but all cancer mortality rate is lower than the mortality in the State through a series of studies have shown. silica dust To groan cancer risk is not high. In addition, the overall mortality rate of lung cancer ten t queue does not increase with the rise in silicosis of the other. Pathology of observation is confirmed, lung disease and silicon groan was not related to fibrosis. These results are instructions. silica dust and silicosis does not cause lung cancer study design as well talk about science. possession of silicosis fell flat up to 6 thousand. and is the largest of its kind in the world today research teams. so its conclusion is reliable and convincing standard, and its significance is. prevention of occupational diseases, but the purpose of ergonomic comfort for the health and efficient security. than the traditional notion of a higher demand. such as dust. such as speaking only from the provisions of pneumoconiosis caused by the appropriate health standards, but considering the slightly lower than this concentration will not occur, but can affect the sight of pneumoconiosis and accuracy. so that the operator have unpleasant. affect their morale, so the ergonomics standard is more stringent than the . so far. ergonomic physical factors as more content. such as temperature changes can affect people's sensitivity and the sensitivity of physical activity, and with the injury related. Therefore, teaching workers studied the temperature comfortable. Other. such as color,[link widoczny dla zalogowanych], noise, lighting and so on have done similar work. Du will be factors in improving productivity and worker health for that matter, such as the traditional training of new workers to pay train an apprentice teacher. This inefficiency. is not standardized, may be some inaccurate teach new workers movement is to promote job training in a dummy when you hear t that can be shortened. reduce costs. and standardization of shift work can affect people's biological rhythms, should study the way a reasonable shift. Some studies that. will be three shifts of three rotation Three to four classes of rotation is conducive to the body to adapt, reduce fatigue and improve attendance. In summary. working people increasingly heavy teaching soap, through improved equipment. to improve the working environment, improved working posture. to achieve the health, comfort ,[link widoczny dla zalogowanych], efficient and safe aim of Occupational Health, an important branch of science.
