The shortcomings of incident-based metrics for worker safety such as total recordable incident frequency rate (TRIFR) are well documented. In particular, a low TRIFR is no assurance against legal liability. There considerable overlap between the literature on presence capacities to make things go well, and jurisprudence in labour workplace law employer due diligence. this article, authors propo...

Coronavirus (COVID-19) is a highly infectious respiratory disease which spread can be effectively curbed by wearing facial masks, especially N95 and surgical masks. In this paper, we develop stylised game-theoretical model to evaluate the impacts of producing selling masks on supply chain profits, safety index consumer social welfare. Firstly, find that as infection probability without protecti...

We examined the relationship between parent-perceived neighborhood safety and children’s physical activity, sedentary behavior, body mass, and obesity status using 9 years of longitudinal data (1999–2007) on a cohort of approximately 19,000 US kindergartners from the Early Childhood Longitudinal Study. Children’s height and weight measurements and parent perceptions of neighborhood safety were ...

In the assessment of long term behavior of the complex system we have to introduce notion of sustainability as the measure for the quality of the system. It is defined as the quality which is measuring the ability of our society to secure and not compromise the ability of future generation to have quality of the life at least the same as our generation. The safety property of complex system is ...

In many cases, crashes at intersections account for over 50% of all urban road accidents. The need to reduce these crashes has fostered considerable research on the development and evaluation of traffic safety at intersections. This paper introduces a micro-level behavioral method for estimating crash potential at signalized and unsignalized intersections for different traffic characteristics. ...

We review at first the principal concepts of system safety. Then we analyze hazards of robot – human interactions – human injury and unsafe communication. We focus on hazard of collision with a human and an appropriate robot behavior mitigating this hazard. After reviewing the principal classes of robot control architectures, we evaluate their effectiveness in obstacle avoidance. Index terms – ...

This letter is in response to the discussion of our recent paper entitled " The effect of parameter uncertainty on achieved safety integrity of safety system " [1]. We are grateful to the discussants for their constructive comments and suggestions, and in particular their insight into our proposed methods to measure safety-related (SR) uncertainty. The detailed response is given below. We agree...

The Flight Operations Risk Assessment System (FORAS) is a risk modeling methodology which represents risk factors and their interrelationships as a fuzzy expert system. A FORAS risk model provides a quantitative relative risk index representing an estimate of the cumulative effects of potential hazards on a single flight operation. FORAS systematizes the process of eliciting human expertise, pr...

We examined the relationship between parent-perceived neighborhood safety and children's physical activity, sedentary behavior, body mass, and obesity status using 9 years of longitudinal data (1999-2007) on a cohort of approximately 19,000 US kindergartners from the Early Childhood Longitudinal Study. Children's height and weight measurements and parent perceptions of neighborhood safety were ...
