Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, th...

OBJECTIVES To determine the effectiveness of protective suits and gloves by biomonitoring. METHODS Fifteen male spray painters at a ship coating factory were studied for two weeks. Workers wore no protective clothing during the first week and wore protective suits and gloves during the second week. Sampling was conducted on four consecutive working days each week. Ethyl benzene and xylene in ...

Daily working activities and functions require a high contribution of hand and forearm muscles in executing grip force. To study the effects of wearing different gloves on grip strength, under a variety of hand skin temperatures, an assessment of the maximum grip strength was performed with 32 healthy male workers with a mean age (standard deviation) of 30.44 (5.35) years wearing five industria...

OBJECTIVES To determine the prevalence and risk factors for symptoms related to gloves, and the relation between symptoms and immunological evidence of type 1 hypersensitivity to latex in a United Kingdom health care setting. METHODS A cross sectional survey was carried out among 773 employees at a British hospital. A self administered questionnaire was used to collect information about sympt...

BACKGROUND A prospective analysis was carried out over a 1-year period to assess gloves used during 100 major and 100 minor oral surgical procedures to test for efficacy of double gloving in oral surgical procedures. PURPOSE The purpose of this study was to assess the efficacy of double gloving technique in preventing cross infection in both major and minor oral surgical procedures. MATERIA...

Since crown size reduction has been observed in 47-trisomy G (M. M. COHEN and R. A. WINER, J Dent Res 44:197-208, 1965; M. M. COHEN, S. M. GARN, and M. A. GECIAUSKAS, J Dent Res 49:460, 1970) with delayed tooth formation timing (S. M. GARN, C. W. STIMSON, and A. B. LEWIS, J Dent Res 49:640, 1970), it is useful to compare the magnitude of crown size reduction with the magnitude of body size redu...

This paper explains why seemingly irrational overconŽdent behavior can persist. Information aggregation is poor in groups in which most individuals herd. By ignoring the herd, the actions of overconŽdent individuals (“entrepreneurs”) convey their private information. However, entrepreneurs make mistakes and thus die more frequently. The socially optimal proportion of entrepreneurs trades off th...

The influence of visual effects for tactile sensation in augmented reality environment is experimentally evaluated. Texture and dent are used as the visual effects. Pitch and brightness difference in stripe textures are used as parameters. Radius and depth of dent are also utilized. At first, preliminary experiment on a few subjects was conducted to find the change in tactile sensation by visua...

Experimental evidence suggests that people tend to be overcon dent in the sense that they overestimate the accuracy of their private information. In this paper we show that risk-averse principals might prefer overcon dent agents in various strategic interactions because these agents help diversify the aggregate risk. This may help understanding why successful analysts and entrepreneurs tend to ...

Beginning in the 1980s, use of latex gloves to protect health care workers against exposure to blood and body fluids increased. Since then, the number of reported cases of latex sensitivity also has increased. Reactions to latex range from contact dermatitis to anaphylactic shock. Low-powder, powder-free, and non-latex gloves provide alternatives to protect health care workers from occupational...
