Physiological responses of people in working faces of deep underground mines

The research studied the influences of high temperature, high pressure, high humidity, noise and other harmful factors in mining conditions on the people health and safety, and investigated the impacts of confined environmental on human physiology factors, including temperature, humidity, noise, pressure,toxic and harmful gases in terms of environmental characteristics in underground mines and an artificial intelligence system for simulation of the environment in a confined space of deep mines. Our results show that the systolic pressure, diastolic pressure, mean pressure, heart rate, respiratory rate, typing test speed and memory level percentage are negatively correlated with temperature value, and positively correlated with humidity value; the human temperature and weight are positively correlated with temperature value, and negatively correlated with humidity value. This research lays the foundation for the study of interaction between the deep confined space environment and safety behavior.

First Exploration on The Reform of Experimental Examination of Physiology in Higher Vocational College Students

Objective：The purpose of this paper is to explore the application effect of diversified assessment mode in physiology experimental examination of higher vocational college students.Method：We selected 173 higher vocational college students as the research group,in the experimental assessment,adopted diversi？ ed assessment model;and selected 192 higher vocational college students as the control group,adopted the traditional assessment method.The pathological examination scores of the two groups were compared,and the research group was investigated by questionnaire.Result：The physiological end term test scores （t=1.973,p〈0.05） and experimental operation assessment scores of the research group were higher than those of the control group （t=1.624,p〈0.05）.The diversified assessment model helps to improve the learning initiative,improve learning interest,foster collaboration and communication ability,reduce learning pressure and reduce anxiety before examination.Conclusion：The diversified assessment model can highlight the cultivation of professional skills and innovation ability,enable students reserve the necessary knowledge through inquiry and cooperative learning,and conducive to sustainable development of students.B
