An intervention to reduce playground equipment hazards.

OBJECTIVES A community intervention trial was carried out to evaluate the relative effectiveness of two methods of reducing playground hazards in schools. The study hypotheses were: (1) a health promotion programme addressing barriers to implementing the New Zealand Playground Safety Standard will reduce playground hazards and (2) the intervention programme will be more successful than providin...

Safe current limits for electromedical equipment and hazards to patients.

clinical diagnosis of definite angina. The women with angina in our study were, on average, 64 years old; they had definite angina determined by two independent, standardized, physician-administered medical histories, which were subsequently reviewed and adjudicated by a panel of three physicians. Although the number of women with angina in our study who actually had coronary disease cannot be ...

Updated proportional hazards model for equipment residual life prediction

Purpose – Most current condition-based maintenance (CBM) systems using proportional hazards model (PHM) assume that enough historical data are available. However, in many practical cases, it is usually costly to collect much historical data prior to real practice (model implementation). This paper aims to focus on the necessity and benefits of updating a PHM with new samples generated in the pr...
