A novel type of reduced graphene oxide (rGO) modified melamine sponges (rGS) filling with paraffin(rGS-pf) is developed for efficient solar-thermal conversion and heat management.The microstructures,filling and holding capacity of paraffin in porous rGS,solar-thermal energy conversion and energy har-vesting efficiency of the prepared rGS-pf have been investigated systematically.The content of rGO nanosheets coated on the skeletons of rGS-pf is only 0.11%,while the loading content of paraffin in the rGS-pf is as high as 97.53%.Based on the solar-thermal conversion property of rGO nanosheets in the rGS-pf and the heat storage ability of paraffin in the rGS-pf,the proposed rGS-pf provides excellent per-formance for heat management.The efficiency of solar-thermal conversion could reach up to 92.5%.The thermo-regulation provided by the proposed rGS-pf is real-time,repeatable and long-term stable.The results in this study provide valuable guidance for developing functional materials for efficient solar-thermal conversion and heat management.

目的 研究护士分层级管理理念应用在护理管理过程中对管理质量的影响效果.方法 以该院2020年1月—2021年1月期间的20名护士作为研究对象,按照随机数表法将其分成对照组(n=10)和观察组(n=10).观察组护理人员采用护士分层级管理理念进行管理,对照组护理人员采用常规管理理念进行管理,然后将同年来该院住院治疗的80例患者按照同样方法分成对照A组(n=40)和观察A组(n=40),对照A组患者经过常规管理理念下培训的护理人员进行护理,观察A组患者经过护士分层级管理理念培训下的护理人员进行护理,展开对照研
医学学术交流、医疗技术国际交流需求也不断增加,因公出国(境)成为我国三甲公立医院吸收并转化国际先进医疗技术的有效手段之一.因疫情发生,三甲公立医院外事出访审批受到严重影响,多数团组暂缓或取消出访.该文结合某三甲公立医院2016—2018年因公出国(境)实际情况,采用SWOT分析,并提出管理策略,以促进三甲公立医院因公出国(境)工作更好发展,达到提高医院核心竞争力的目的.
目的 分析在医院感染科陪护的过程中,对护理人员实行预见性护理管理模式的应用及效果探讨.方法 于吉林省一汽总医院感染科2018年9月—2020年4月期间选取16名护理工作人员作为研究对象,另由1名主管护师与1名主任护师负责监督指导,采用随机数表法将其进行分组,即观察组(预见性护理管理模式)、常规组(传统护理管理模式),各8名,总结护理过程中出现的相关问题,对比两组工作人员预见性护理管理实施前后的相关护理管理指标(陪护管理、环境管理、质量管理)水平状态以及所看护的患者对护理工作的满意程度.结果 实施前,两组工
