China's evaluation on plateau soldier's performance mainly focuses on the valuation of physical ability.Comparatively, few attention is paid on the changes of individual neuropsychological function, which refer to the changes of soldiers' emotion, psychological activity, and cognitive function, including perception, memory, thinking ability and attention.Therefore, when setting the criterion to evaluate the performance of plateau soldiers,impacts from both neuropsychological and physical elements should be involved.展开更多

Methods: 200 outpatients in our hospital from January 2019 to December 2019 were retrospectively analyzed and divided into conventional group and refined management group according to the implementation time of refined management mode of dispensing work in outpatient pharmacy. Among them, the conventional group adopted the routine management mode, while the refined management group adopted the refined management mode. The incidence of prescription dispensing errors, the time spent on prescription dispensing and the waiting time for patients to take medicine were compared, and the satisfaction of patients in the two groups was compared. Results: the incidence of prescription dispensing error, the time spent on prescription dispensing and waiting time for patients in the refined management group were significantly lower than those in the conventional group, and the satisfaction of patients was higher than that in the conventional group, P < 0.05. Conclusions: the refined management mode can reduce the incidence of prescription dispensing errors and improve satisfaction of patients, shorten the time spent in prescription dispensing and the waiting time for patients to take medicine.展开更多

Methods: the scope of the experiment was selected from the subjects of outpatient pharmacy workers in our hospital from April 2020 to March 2021, and the working conditions under different management modes were analyzed. According to the time group, the traditional management mode was applied from April 2020 to September 2020, and the humanized management was applied from October 2020 to March 2021 to compare the improvement of work efficiency of outpatient pharmacies. Results: in terms of work quality, the work enthusiasm of the observation group was higher, especially after humanized management was carried out, the number of people with excellent work enthusiasm was significantly increased, with statistical significance (P < 0.05). At the same time, in the survey of satisfaction with medication consultation, the satisfaction evaluation of outpatient patients to the staff in the observation group was (96.3±2.7) points, better than that of the control group (90.5±1.8) points, and the difference was statistically significant (P < 0.05). Conclusions: the adoption of humanized control mode can improve the work quality of outpatient pharmacy staff, improve their working status, which makes them to better serve the outpatient patients who take drugs, and strengthen the quality of drug control, and it has the value of popularization.展开更多

According to the principle,an ammonia compressor,whose working conditions are based on key operational parameters of the whole ammoniarecovery system, is the mainly energy-consumption part of ammonia-recovery system in the modified equipment of flax fiber. A generally mathematical model based on work efficiency of an ammonia compressor is founded,which is available to rate effective work and energy consumption of the ammonia compressor. The optimum operation-efficiency of the ammonia compressor is chosen as the goal to analyze and calculate the key operational parameters of the ammonia-recovery system. In the above analyzing and calculating,a mathematical model on ammonia flowing from the reactor to the register 1 is developed,in order to provide further understanding of the principle of an ammonia-recovery system. At the meantime,the ammonia flow regime in the pipeline and the process of ammonia inflation and deflation from the reactor to the register 1 are taken separately into account in the model. An iterative method is for obtaining parametric solutions of the mathematical model on ammonia flowing from the reactor to the register 1 and the key operational parameters of the ammoniarecovery system. A parametric analysis is put forward to complete showing the ammonia velocity or the state of the reactor and the register 1. The key optimized parameters will be achieved in term of the minimum efficiency after comparing the work efficiencies of an ammonia compressor at different working conditions.展开更多
