Objective To analyze the impact of sporadic cases of COVID-19 on the work of Transfusion Department, so as to explore the countermeasures. Methods The admission of inpatient departments, the reception of outpatient(including emergency) departments, the workload of transfusion department(including blood typing, unexpected antibody screening and cross matching), and the consumption of blood components in the Xijing Hospital between October and November in 2021, during COVID-19 outbreak, were collected. All the above data was statistically compared to the data in same period in 2018, before the COVID-19 outbreak. Results Due to the COVID-19 epidemic, there was a significant decrease in number of inpatients(280±157.1 vs 340.4±110.2), outpatient(including emergency)(8 359±3 615 vs 10 151±3 225), the workload of blood typing(272.0±132.4 vs 341.6±110.4), unexpected antibody screening(78.26±42.22 vs 98.51±43.53) and crossmatch(237.2±99 vs 475.7±155.6), as well as the consumption(U) of all blood components(457.9±50.32 vs 579.4±62.51) in the Xijing Hospital(P<0.05). In detail, the epidemic had the most direct impact on the number of inpatients and outpatients, which shrank continuously on the 2nd day after official announcement of the new COVID-1 cases. While the workload of blood typing, unexpected antibody screening and crossmatch decreased slightly, with a lag, usually on the 2nd, 3rd and 5th day after official announcement. The decrease of the usage of red blood cells and plasma began from the 7th day after the new epidemic to the 6th day after the end of the epidemic. However, the usage platelets and cryoprecipitate coagulation factors decreased from the 8th and 10th day after the new epidemic to the 2nd and 6th day after the end of the epidemic, respectively. Conclusion The daily work of Blood Transfusion Department has been seriously affected by sporadic COVID-19 epidemic. The working mode, staff structure and inventory ratio of blood components should be adjusted and optimized instantly to maintain the normal conduct of medical treatments in hospitals and ensure the safety of patients.

To reduce the randomness and uncertainty in the evaluation of library knowledge service ,the paper presents an evaluation model for the library knowledge service performance built on the improved fuzzy comprehensive evaluation model .First ,a questionnaire was designed for the experts in the field of library science and users to learn the importance degree and satisfaction degree of the index system . Then ,a statistical analysis was made of the results .The importance degree given by experts was turned into the evaluation index weight through analytic hierarchy process .The satisfaction degree was used as the fuzzy degree of membership . Finally ,the fuzzy comprehensive evaluation method was used to evaluate the service quality of The library of the Fourth Military Medical University . Through the comprehensive analysis of the evaluation result ,effective decision-making methods were obtained and subsequently applied in the library management .T he results show that those methods can improve the service quality of libraries and help to set up a standardized management system .

目的 探讨两种不同标注方式医学图谱(文字标注和数字引注)对阅读效率、方式的影响,及其影响因素.方法 通过眼动技术和满意度测量来考察阅读和眼动指标.结果 (1)标注方式对图谱阅读指标有影响,反应时间和满意度均存在统计学差异(P＜0.05).(2)标注方式对图谱眼动指标有影响,注视持续时间、注视次数、眼跳幅度、眼跳次数均存在统计学差异(P＜0.05).(3)标注方式对眼动轨迹有影响,文字标注类图谱眼动轨迹较散,数字引注类较集中.结论 文字标注类图谱阅读效率较高,满意度较差,阅读目的性不明显;数字引注类图谱阅读效率较低,满意度较高,阅读目的性明显.
