in this paper we propose and construct fuzzy algebraic additive model, for the estimation of risk in various fields of human activities or nature’s behavior. though the proposed model is useful in a wide range of scientific fields, it was designed for to torrential risk evaluation in the area of river evros. clearly the model’s performance improves when the number of parameters and the actual d...

The contamination of ores with wastes or materials of lower than the cut-off grade is referred to as dilution. Dilution is an undesirable phenomenon that, on one hand, reduces the product grade and, consequently, reduces the sales prices and, on the other hand, adds an extra cost to waste production. Therefore, studying and evaluating the dilution risk is important in mining, and especially in ...

OBJECTIVE In this study, we aimed at exploring the association between work-related musculoskeletal disorders (WMSDs) and work organization based on a case-control study. METHODS A total of 1938 workers who claimed to suffer from WMSDs were selected from Beijing, Henan, Hubei, and the Guangdong province. The control group consisted of 2009 workers employed in similar industries without severe...

Musculoskeletal discomforts/pain-are common occupational problems in healthcare workers whose job tasks involve repetitive motion and assumption of awkward positions. They are major causes of disability worldwide often resulting in job modification and outright resignation by many healthcare practitioners. This work aimed to assess the prevalence and risk factors for musculoskeletal discomfort/...

Risk management is about reducing the likelihood of errors. Its particular aims are to reduce errors that are costly in terms of damage, discomfort, disability, or distress to an individual and to limit financial loss to an organisation. Risk management achieves this through detecting, reporting, and correcting actual or potential deficiencies in the process of care that, however small, could l...
