ABSTRACT
This paper introduces the characteristics and classification of “virtual reality (VR)” technology. Based on the “VR” training plan, training target, training stage and training mode of US army medical staff, combined with the current difficulties and challenges from the medical service work in PLA overseas base, this paper proposes some enlightenment for the construction and training of medical service force in base, so as to provide a reference for improving the medical service support capacity.
ABSTRACT
Objective To analyze the spectrum and characteristics of common diseases in Chinese escort navy fleets in Aden Gulf, providing references for optimizing the allocation of medical resources and improving the efficiency of medical service. Methods A total of 3 068 navy soldiers who served in four escort missions between 2013 and 2016 in Aden Gulf were included in the present study, and they were marked as batch A, B, C and D according to the task sequence. The records of outpatient and emergency departments, data from weekly medical report and data from summary of health service were collected for analyzing the circadian disease incidence, morbidity per day and the composition of diseases. Results The incidence of diseases took a declining tendency from the beginning to the end of the mission. The latter two escort fleets had a significantly lower morbidity per day than the former two escort fleets (P0. 05). Conclusion With the normalization of the escort missions, the morbidity per day of the escort soldiers declines in the later escort fleets. More attention should be given to improve the sleeping quality and reduce the occurrence of insomnia while still keeping an eye on common diseases.
ABSTRACT
Objective To analyze the difference in sustained attention and vigilance level between male and female crews during long-term sailing, so as to provide reference for reasonable assignment of operators on duty and improving the comprehensive management ability of warships. Methods A self-made demographic survey questionnaire was adapted with continuous performance lest (CPT) on computers to investigate the attention and vigilance abilities of 95 crews (70 males and 25 females), and the obtained data were analyzed statistically. Results The response ability and accuracy rate of the 95 crews were decreased at the beginning stage and then increased, with the lowest points seen at the mid-term stage. The average response time of the male crews was significantly longer than those of the female crews at the beginning and late stage of the sailing, while it was significantly shorter at the mid-term stage(P<0.05). The response accuracy rate of male crews was significantly lower than that of the female crews at the beginning and later stages of sailing while it was significantly higher at the mid-term stage (P<0.05). Conclusion There is difference between male and female crews in the sustained attention and vigilance level during long-term sailing. The attention stability of male crews is better than that of the female crews, while the attention level of female crews is superior, but it is easier to be affected by negative factors.
ABSTRACT
Due to the extremely challenging climate of the Gulf of Aden and the complicated hygiene conditions of the surrounding countries, the soldiers of PLA Navy escort fleets are easily vulnerable to various regional infectious diseases. It is quite onerous to implement the plague controlling mission. This report described a case of hepatitis A virus infection during an operation of PLA Navy escort fleet on the sea in the Gulf of Aden area, introducing the basic symptoms, main management methods, and putting forward the countermeasures and recommendations from the perspective of infectious disease control and prevention on the sea.
