Analysis of intervention strategies for coal miners' unsafe behaviors based on analytic network process and system dynamics

Publication date: October 2019Source: Safety Science, Volume 118Author(s): Kai Yu, Qinggui Cao, Changzhen Xie, Nannan Qu, Lujie ZhouAbstractIn recent years, the safety situation in Chinese coal mine enterprises has been steadily improving, however, major accidents occur occasionally. Statistics reveal that human unsafe behaviors are the main cause of accidents. In this paper, based on the Fishbone Diagram, the influencing factors of unsafe behaviors of coal miners were identified from 5 aspects including individual factors, physical environment, safety leadership, safety management, and group factors. Next, the indicators system of influencing factors of unsafe behaviors for coal miners was established, and the weights were analyzed by the Analytic Network Process (ANP). On that basis, the primary and secondary indicators of the influencing factors were ranked. The weights determined by ANP were taken as the influencing coefficients between variables, and the System Dynamics (SD) model of the unsafe behaviors of coal miners was established. The related simulations were also conducted on the intervention strategies using this model. By combining the weights determined by ANP and the simulation results based on the established SD model, the influencing factors identified were reordered. Finally, this paper proposed the combination intervention strategies mainly from the aspects of safety management, individual factors, group factors, safety leadership and physical environment, ...

Authors: Tranchant C Abstract Several environmental toxics are known to induce or to increase occurrence of Parkinson disease while other toxics can provoke basal ganglia necrosis and dopa resistant parkinsonism. After this introduction, the relationship between environment and parkinsonism will be illustrated by 3 short papers: interaction gene-environment, manganese induced Parkinsonism and the Caribbean Food toxins Parkinson plus syndromes.

Infections with herpes simplex virus type (HSV)-1 and HSV-2 are distributed worldwide. Although standard therapies with acyclovir and other synthetic drugs are available, the safety and efficacy of these drugs are limited due to the development of drug resistance and adverse side effects. The literature on essential oils and isolated compounds was reviewed regarding their antiviral activities against HSV-1 and HSV-2. The present overview aims to review experimental data and clinical trials focusing on the antiviral activity of selected essential oils and isolated oil components. HSV was found to be susceptible to many esse...
