How to Improve Employee Engagement—Based on Employee Engagement Questionnaire Survey of KNBW

全球化竞争,技术创新,业务转型……,在工业4.0、“互联网+”的经济发展时代到来之际，企业面临的市场竞争环境愈发激烈和多变,促使企业更加重视对员工的激励和保留,并希望员工可以全身心的投入到工作中,提高员工的敬业度，为公司创造价值。 员工敬业度是一个和组织行为学、心理学以及人力资源管理都密切相关的一个主题。近年来学者们的理论研究和咨询机构的实践研究都发现：员工敬业度对企业的经营业绩起到重要作用。高敬业员工可以为企业带来更满意的客户和更好的营业收入。这也是越来越多的企业开始重视和关注员工敬业度的原因所在。由于员工敬业度的研究时间相对有限，目前还没有统一的定义和系统完善的理论体系。 本文梳理了近...Global competition, technology innovation and business transformation… Along with the age of Industry 4.0 and Internet +, the fierce and unpredictable commercial environment makes us focus more on employee motivation and retention.

Discuss on the Relief Mechanisms of Adverse Drug Reaction in China

药品是人类与疾病斗争过程中必不可少的工具和武器，但是药品也是一把双刃剑，在治病的同时也可能给患者带来有害的反应，这是伴随药品而存在的客观现象和医学风险。由于我国在药品不良反应损害救济方面还存在许多不足，药品不良反应的受害者在正常服用药品过程中受到损害却只能自担风险。本文采用比较研究法和系统分析法，通过对我国与世界各国药品不良反应损害救济机制的比较，指出我国在药品不良反应损害救济方面存在的不足，就我国药品不良反应损害救济机制的完善提出建议和对策。 全文包括引言、正文和结束语三部分，其中正文部分分为三章。 第一章为“药品不良反应损害救济机制概述”。本章介绍了药品不良反应与药品不良反应损害救济机...The drugs are the essential tools and weapons in the human struggle with disease, but it is also a double-edged sword, may bring harmful reaction to patients in the treatment.

高显色指数LED光谱配比与色度参数的关系

为了提高LED光源的显色性一般需要改变不同的荧光粉成分,理论上利用不同峰值的荧光粉配比可以实现类似的色温和显色指数。我们采用典型的蓝光LED、3种不同峰值波长的绿色/黄绿色荧光材料与典型红色荧光材料进行5种基本光谱的组合,对每种组合的色度学参数包括色坐标、相关色温、显色指数等进行了仿真计算,并对相近色温下的技术方案和显色性的关系进行了统计和分析。结果表明,在这一技术方案下色温和显色指数在可以较好地确定白光LED光谱的整体形态,同时更高的显色指数可以更好地约束所能采用的配比。国家重点研发计划(批准号:2017YFB0403705

光环境生物效应及其模拟实验装备研究进展

光是人、动物和植物赖以生存的基本条件。光环境作为一种物理环境因素,其生物效应具有十分重要的理论和应用价值。光环境对人的生理、心理及行为产生重要影响,对动物昼夜节律、定位系统和生长繁育的影响也已受到诸多关注;同时,光是植物赖以生存的基础,是植物一切生化反应的能量来源。综述了光环境生物效应的研究进展,指出已有的文献仅限于以复色光为研究对象,对特定波长的光效应、光暴露时间及光质效应的研究甚少。进一步阐明目前光环境模拟实验装备的研制所遇到的关键\"瓶颈\"是缺乏能够在一定波长范围内输出较高功率的单色光光源,且无配备生物学培养装置,不可能在实验室实现对单色光环境的模拟。因此,其发展当务之急是先构建光环境暴露的科学实验平台。同时对光环境生物效应的研究方向及光模拟实验装备的应用前景进行了展望。中国科学院科研装备研制项目(YZ201104,YZ201303);中国科学院STS计划(Y6I0921A20)资

Separation and purification of catalpol from Radix Rehmanniae

An ultrasonic extraction technology of preparing catalpol from Radix Rehmanniae was optimized by a uniform experimental design.The optimum conditions for ultrasonic extraction were thus established: 68% (vol) ethanol aqueous solution as extraction solvent,the volume(ml) to mass(g) ratio of extraction solvent to feed of 5∶1,the ultrasonic treatment time of 36 min.The crude catalpol obtained from the optimized ultrasonic extraction technology was further purified by selective adsorption with macroporous resin.The adsorption capacities and desorption yields of ten kinds of macroporous resins for catalpol were investigated.The results showed that H103 resin possessed the best performance.The properties of dynamic adsorption and desorption of H103 resin for catalpol were subsequently investigated on adsorption column.The optimum conditions for adsorption and desorption were determined.The concentration of catalpol in the loaded sample solution was 6.15 mg·ml-1,the flow rate was 1.0 ml·min-1,the volumetric percentage of ethanol in the eluting solvent was 75%,the elution flow rate was 0.5 ml·min-1 and the elution volume was 3.33 BV(bed volume).Under the above conditions,the purity of catalpol product eluted from the column packed with H103 resin reached 62.39% while that of the crude catalpol was only 10.01%

In the copresence of CO and H-2 single-crystalline Pd tetrapod nanocrystals have now been successfully prepared. The Pd tetrapods are enclosed by (111) surfaces and are yielded through hydride formation. Density functional theory calculations revealed that the formation of PdHx in the presence of H, reduces the binding energy of CO on Pd and thus helps to decrease the CO coverage during the synthesis, which is essential to the formation of the PdHx tetrapod nanocrystals. In addition to tetrapod nanocrystals, tetrahedral nanocrystals were also produced in the copresence of CO and H-2 when the reaction temperature was ramped to further lower the CO coverage. Upon aging in air, the as-prepared PdHx nanocrystals exhibited a shape-dependent hydrogen releasing behavior. The conversion rate of PdHx tetrapod nanocrystals into metallic Pd was faster than that of tetrahedral nanocrystals.MOST of China 2011CB932403 2009CB930703 NSFC 21131005 21021061 20925103 20973139 21133004 Fok Ying Tung Education Foundation 121011 Fundamental Research Funds for the Central Universitie

Metal films containing just a few layers of atoms can be fabricated on substrates using deposition techniques(7), but the production of freestanding ultrathin structures remains a significant challenge. Here we report the facile synthesis of freestanding hexagonal palladium nanosheets that are less than 10 atomic layers thick, using carbon monoxide as a surface confining agent. The as-prepared nanosheets are blue in colour and exhibit a well-defined but tunable surface plasmon resonance peak in the near-infrared region. The combination of photothermal stability and biocompatibility makes palladium nanosheets promising candidates for photothermal therapy. The nanosheets also exhibit electrocatalytic activity for the oxidation of formic acid that is 2.5 times greater than that of commercial palladium black catalyst.NSF of China 20925103 20871100 20721001 20703032 MOST of China 2009CB930703 2011CB932403 Fok Ying Tung Education Foundation 121011 NSF of Fujian 2009J06005 Key Scientific Project of Fujian Province 2009HZ0002-
