BACKGROUND The consequences of fatigue for the health and safety of seafarers has caused concern in the industry and among academics, and indicates the importance of further research into risk factors and preventive interventions at sea. This review gives an overview of the key issues relating to seafarer fatigue. MATERIALS AND METHODS A literature study was conducted aiming to collect public...

This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...

Fatigue is known to be a major risk for safety in aviation. Even if an accurate quantification of the contribution of fatigue in accidents is currently impossible because fatigue is not systematically investigated by a standardised procedure, it is classified as one of the “most wanted” factors by the National Transportation Safety Board (NTSB): “The Safety Board has long been concerned about t...

Background & Aims of the Study: Fatigue is one of the most important issues relating with safety and other aspects of human life. To understand fatigue and its relative factors and causes, there is a need to useful instruments, such as self-reported scales. The purpose of this study is to identify and present useful self-reported scales to measure fatigue. Materials & Methods: Data were extrac...

Many factors can contribute to safe and unsafe work practices in National Park Service (NPS) activities. Prior research is reviewed to highlight how factors influencing employee safety occur at multiple levels. Individual characteristics contributing to employee safety include stress and fatigue, and how they influence decision making, judgments, and behaviors. Group characteristics include how...

Keywords: Damage equivalence factors Fatigue load model Equivalent length Weigh-In-Motion Traffic load model Monte-Carlo simulation a b s t r a c t The fatigue design of bridges under variable amplitude traffic loads is not straightforward. To simplify the task, the current Eurocode provisions apply fatigue load model 3 and damage equivalence factors (k). However , the fatigue load model and th...

MS illness is a self- safety and inflammatory illness in Central Nervous System in which Myelin Sheath and Axon of neuronal cells of the brain and the spinal cord is destroyed by the Safety System, and the level of its prevalence is two or three times more in women rather than men. The most important complications of this illness are fatigue, cramp, shake, the lack of balance, and walking disor...

Safety and productivity in the workplace are intimately related to worker health. A workplace may have chemical, physical, biological, and/or psychosocial hazards that have the potential to impact physical and psychological well-being. How these hazards are managed in the workplace is key. A workplace in which these hazards are wellcontrolled, with an active culture of health and a supportive w...
