Imamura, T., and Ikeda, M. (1973). British Journal ofIndustrial Medicine, 30, 289-292. Lower fiducial limit ofurinary metabolite level as an index ofexcessive exposure to industrial chemicals. Utilization ofthe lower fiducial limit (P = 0-10), rather than the mean, as an index ofexcessive exposure to industrial chemicals is discussed. Cases of exposure to trichloroethylene, phenol, and toluene ...

OBJECTIVES The level of benzene exposure in the petrochemical industry during regular operation has been well established, but not in turnaround (TA), where high exposure may occur. In this study, the characteristics of occupational exposure to benzene during TA in the petrochemical companies were investigated in order to determine the best management strategies and improve the working environm...

BACKGROUND Risk factors for sports injuries include characteristics and behaviors of athletes and characteristics of sports and the environment that are associated with some measure of risk of injury. OBJECTIVE To introduce risk statistics to clinicians evaluating studies of sports injuries. METHODS Plain-language review of risk statistics and their practical application to sports injuries....

This report considers the historical origin of the current beryllium occupational exposure limit (OEL) and the evidence that led most authorities to conclude that it was adequately protective against clinically evident chronic beryllium disease (CBD). Nearly 40 years later, during the late 1980s, it was shown that in addition to CBD, beryllium can cause asymptomatic sensitization and asymptomat...

This study aims to establish the occupational exposure limit (OEL) in the air for workplace of warfarin based on the available toxicological studies and field investigations by using questionnaire and air monitoring. The clinical therapeutic dose was used as lowest observed effect level (LOEL), and no observed effect level (NOEL) was achieved by using a safety factor. The highest concentration ...

I n 2004 Member of the European Parliament (MEP) Liz Lynne was Shadow Rapporteur on a proposed European Union directive for what is now the Alliance of Liberals and Democrats in Europe. EU Directive 2004/40/EC aimed to regulate worker exposure to electromagnetic fields. “I did a lot of research work on it,” MEP Lynne said. “I contacted medical experts and consulted manufacturers to understand w...

Data mining introduces new problems in database security. The basic problem of using non-sensitive data to infer sensitive data is made more difficult by the “probabilistic” inferences possible with data mining. This paper shows how lower bounds from pattern recognition theory can be used to determine sample sizes where data mining tools cannot obtain reliable results.
