Under the"Four Specials"conditions(special environments,special tasks,special equipment,and special personnel),complex tightly-coupled human-machine systems exhibit distinct characteristics such as human-in-the-loop,frequent human-machine interactions,and significant mutual influence between humans and machines.These features lead to prominent and typical human related safety issues.Through aggregating knowledge from literature review,accident case studies,and engineering practice,this paper elaborates on the characteristics of complex tightly-coupled human-machine systems,clarifies the definition of human related safety(including its research subjects,topics,and methods),and provides a systematic analysis framework on the causes of human related safety from a whole life-cycle perspective of system development.Furthermore,theoretical hypotheses are proposed for human related safety,along with its fundamental scientific research questions and methods.

Objective To study face recognition rule of Chinese subjects during judging the differences of facial recognition of race,gender and their joint property.Methods Eye tracking technique and moving window experimental method were used.Results The present results showed that,in facial race recognition,gender recognition and joint property recognition,the key area of face recognition was eyebrow and eye.In face recognition process,the dominant area in face of information acquired was right facial area.The key brain area of facial cognition was right brain area.Conclusion The recognition performance of face racial recognition is the best than face gender recognition and joint property recognition.Asymmetrical perception effect in human face area is appeared in facial recognition.
