Occupational asthma may be defined as asthma induced by exposure to an inhaled agent (or agents) in the workplace. Its presentation is sometimes dramatic. Occupational exposure to platinum salts, for example, has been known to induce asthma in over 50% of an exposed workforce. For those affected, the consequences are often devastating, while the economic effects for an industry may be no less p...

Phase-shifting interferometry with a genetic algorithm is proposed. The correction of unknown phase-shifting error is an important task in general phase-shifting interferometry. Since phase-shifting errors generate twin image noise in a reconstructed image, we can reduce the phase-shifting errors indirectly by trying to eliminate the twin-image noise in the reconstructed image. By Zernike polyn...

Occupational therapy is involved in disability prevention and health enhancement through the prevention of occupational dysfunction. Although many occupational dysfunction scales exist, no standard method is available for the assessment and classification of occupational dysfunction, which may include occupational imbalance, occupational deprivation, occupational alienation, and occupational ma...

OBJECTIVES The aim of the study was to develop a model of basic occupational health services (BOHS) in Baoan, which could provide occupational health services (OHS) universally for workers and control occupational hazards. METHODS Steps involved in the BOHS strategy included construction of the BOHS system, capacity building, health training and education, surveillance of workplaces and the h...

Occupational asthma is the most common form of occupational lung disease in the developed world at the present time. In this review, the epidemiology, pathogenesis/mechanisms, clinical presentations, management, and prevention of occupational asthma are discussed. The population attributable risk of asthma due to occupational exposures is considerable. Current understanding of the mechanisms by...

BACKGROUND Uganda has a severe health worker shortage and a high demand for health care services. This study aimed to assess the policy and programmatic implications of task shifting in Uganda. METHODS This was a qualitative, descriptive study through 34 key informant interviews and eight (8) focus group discussions, with participants from various levels of the health system. RESULTS Policy...

Thermal energy storage (TES) system has been introduced as a practical facility for shifting load from peak hours to off-peak hours. Because of different energy consumption during day and night, peak and off peak period is created on load curve. Ice storage technology which is a kind of TES system, is implemented in different points of the world with the purpose of solving load shifting problem...

background : exposure to formaldehyde (fa) causes irritative effects and induces nasopharyngeal cancer; the interna­tional agency for research on cancer (iarc, lyon) classified fa as carcinogenic to humans, group 1. many studies have been published so far concerning the occupational exposure of industrial workers, embalmers, pathologists and anatomists to fa but very few data regarding medical ...

This paper describes the application of an important tool which can capture shifting information from pilots’ visual attention data. In order to investigate the shifting information, the shifting state space is defined by visual tracking, visual interference and visual dormancy. Using this analysis, the movement of pilots’ visual attention can be completely measured. The results that the foreca...
