ABSTRACT
Objective:To explore the application of micro-lesson-based exploratory teaching in postgraduate emergency clinical teaching.Methods:A total of 48 intern graduate students in the Emergency Department of Shengjing Hospital affiliated to China Medical University from January 2019 to December 2019 were selected as the research objects. According to the admission time, they were divided into observation group (28 cases) and control group (20 cases). The control group used traditional teaching. The observation group adopted exploratory teaching based on micro-classes. Theoretical and practical operating ability, basic clinical quality and clinical thinking ability, as well as the evaluation of teaching effect and the satisfaction with teaching method and teaching quality were compared between the two groups. SPSS 22.0 was used for t test and chi-square test. Results:The theoretical and practical performance scores of the observation group improved more than those of the control group ( P<0.05). The basic clinical quality and clinical thinking ability scores of the observation group improved more than those of the control group ( P<0.05). The improvement of the observation group's learning interest, learning efficiency, autonomous learning ability and comprehension memory scores was greater than that of the control group ( P<0.05). The observation group's satisfaction with teaching methods and teaching effects was significantly higher than that of the control group ( P<0.05). Conclusion:The use of micro-class-based exploratory teaching in postgraduate emergency clinical teaching can enrich students' theoretical knowledge, increase their learning motivation and interest in learning, and improve their practical ability, basic clinical quality and clinical thinking ability, which is a teaching method worth promoting.
ABSTRACT
Objective To investigate the physical fitness status of stationed on an island and the influence factors of military operational ability in order to take effective intervention measures to cope with the problems encountered by the garrison force.Methods The outdoor environment heat intensity of the island was monitored and evaluated by thermal environment monitors.The physical fitness of thirty-eight soldiers randomly selected was evaluated by measuring VO 2max. Ninety soldiers stationed on this island were selected by random sampling , for whom questionnaires and interviews were designed, involving the influence factors of military operational ability .Results This island was a typical humid-hot environment, with high temperature , high humidity and high radiation .The physical fitness of soldiers declined obviously because of the typical humid-hot environment.The top five working environmental factors were high temperature , humidity, solar radiation, wind and seasonal drying .The top five personal factors were physical fatigue , overtraining, injury, mental fatigue and lack of sleep .Conclusion Considering the obviously decreased physical fitness of soldiers caused by the typical humid-hot environment , how to assess military combat effectiveness and how to determine whether the level of combat effectiveness can meet the actual needs of tropical combat , requires scientific indicators and criteria of evaluation .
