In order to make a system safer, it is necessary to determine which hazard should be removed by considering the interactions of all hazards in the process. In this study, the influence of the hazards related to iron works in a construction firm is examined by Bayesian network approach. If only the most important hazard is identified and removed from the work environment, it may be erroneous to comment on the levels of the remaining hazards. A Bayesian network is proposed to remove this problem. If there is more time and budget than planned for a process, these capacities will have to be reduced in other processes...

In this study, common flame retardant fabrics were treated with single washing or abrasion and their interactions to simulate the wearing away during use. The changes in thickness, mass/m2 and protective performance of the fabrics under both flame and radiation environments were evaluated. It demonstrated that the protective performance was firstly increased after washing or abrasion, and then decreased with further increasing washing or abrasion cycles. After certain treatment cycles, the combined effect of washing and abrasion was significantly greater than the single effect of washing or abrasion alone...

Traditional 'nine-to-five' working schedules do not consider individual characteristics. We identify what types of employees suffer from the adverse effects of work arrangements on their sleep regimen based on a survey of Estonian creative research and development (R&D) employees (N = 153). We present ordinary least squares and ordered probit regression estimates and recursive structural equation model estimates of the employees' perceived level of sleep regimen disruption. We find that evening-type employees, women and employees with a lower creative intensity of work perceive with a significantly higher probability that work limits their sleep, while employees having flexibility in both working time and workplace feel less impacted by work-driven constraints on their sleep regimen...
