Specifically, it is unclear how the inclusion of workers in training materials may affect how mineworkers' perceive a hazard. The goal of this paper is to examine if the presence of workers in the context of hazards affects how mineworkers' assess the risks. Researchers collected risk ...
OS and disease-free survival (DFS) were estimated by the Kaplan–Meier method and compared using the log-rank test. Cox’s proportional hazards regression model was used to analyze independent prognostic factors. Model performance was assessed with Harrell’s concordance index (C-index). The ...
Accurate monitoring of runoff from small and medium-sized rivers is of great significance for ecological stability in arid areas. However, it is difficult to accurately retrieve the flow of small and medium-sized rivers by remote sensing.
Remote sensing technologies, GIS (Geographic Information System) database merging the surface and remote sensing data, numerical hydrological predictions and the traditional means can greatly improve the management of flood hazards. The paper provides a brief overview of the satellite data processing ...
Environmental risks to humans, the first database of valence and arousal ratings for images of natural hazards Introduction The perception that contact with nature provides harmony and balance to humans is ancient. However, after the industrial revolution, human societies became increasingly urban, with...

The risks posed by hazards identified in OPHAZ reports should be treated following service-specific aviation risk management (AVRM) principles outlined in chapter7. OPHAZ为报告所有航空和与航空相关的危险使用,在这样危险结果之前在发生。 风险由在OPHAZ报告辨认的危险摆在了应该对待跟随在chapter7概述的有...
by non-primary risks is informative many conventional survival analysis methods are not applicable; the proportional hazards assumption is usually violated at population level and the observed crude hazard rates are no longer estimators of what they would have been in the absence of other risks. In...
Let’s examine some of these hazards and discuss how to mitigate the potential harm. Cold: Extremely low temperatures can cause all kinds of problems with modern electronics, including cameras. Batteries don’t hold their charges very well in frigid conditions, so you need to carry extra ...
