With the widespread application of unmanned aerial vehicles (UAVs), flight safety issues have gradually become prominent. To improve level UAV flight, a conceptual model was constructed through groups unsafe behaviors based on Swiss cheese (reason model). The relationship network built after using two-mode and one-mode social analysis, influence mechanism were studied by basic characteristics c...

introduction: construction phase in industries is a dynamic process that is naturally and intrinsically dangerous and as it becomes more complicated, the accidents rate also increases. one should note that without considering a model, one could not obtain useful and reliable information and method to prevent accidents. therefore, to achieve useful methods for preventing accidents, it is desirab...

In the present study, we examined a bidimensional model of acculturation (which includes both heritage and U.S. practices, values, and identifications) in relation to hazardous alcohol use, illicit drug use, unsafe sexual behavior, and impaired driving. A sample of 3,251 first- and second-generation immigrant students from 30 U.S. colleges and universities completed measures of behavioral accul...

Objective: High risk behaviors among women can have detrimental consequences on this critical group of society and its increasing rate expose them to more serious dangers. In the light of these issues, the present study aimed to assess the prevalence of high risk behaviors of women living in Tehran. Hopefully, the study results may help take some measures to decrease high risk behaviors and sol...

background: all recent accident models emphasis on multi causality of accidents. the suggested models emphasized on human roles in accident occurrence. the results of recent decade's studies have shown that the main causes of accidents are human and his/her unsafe acts. nowadays, application of warning signs is an important way to decrease unsafe acts . methods: in this study, the unsafe acts o...

Traffic accidents occur frequently in Internet of Things (IoT) safety system. are largely caused by drivers’ unsafe driving behaviors the process driving. Aiming at problem low real-time warning driving, this paper proposes a model to detect driver behavior. Firstly, according target detection for positioning, combined with Pose Estimation identify variety behaviors, same time, rating is built ...

Recent evidence suggests that the burden of new HIV infections in developing countries is concentrated among young people and females. Even with knowledge of how to protect oneself from infection, such information may not always be usable in daily situations of economic and social disadvantage that characterize the lives of many young people and women in poor countries. Using household survey d...
