    人类已经进入21世纪,随着社会的发展,现代科学技术与管理技术的提高,信息量越来越大,各类管理信息趋于多元化、复杂化,人类对信息的处理和管理工作也就变的很重要。随着我国单位管理不断的改善,对单位人事管理的效率也在不断的提高。在目前的某单位的人事管理中,采用的是简单的人事管理软件。这类软件需要在特定的电脑上运行,不能通过其他电脑来查看相关的信息,这给信息的汇总、统计造成了很大的不变,降低了单位的人事管理效率。随着互联网和移动互联网的高速发展,人员的活动范围也越来越大,这类的管理软件已经不能满足单位人员管理的需求,在这种情况下,建立一套基于B/S结构的单位人事信息管理系统就显得非常有必要。 本系统...Mankind has entered the 21st century, with the development of society, modern science and technology and improve management techniques, increasing the amount of information, various types of management information tends to be diversified and complicated, human information processing and management of it It becomes very important.

    目的:羊膜是目前应用最广泛的构建组织工程角膜上皮的载体。但在临床应用中发现,基于羊膜构建的组织工程角膜上皮在移植术后角膜的透明度恢复并不理想。目前认为,羊膜基质的纤维细胞层及疏松的海绵层可能是影响羊膜透明度的主要原因。因此,本研究对传统去上皮羊膜(DAM)进行改造,制备一种新型的超薄羊膜(UAM)载体,并评估其生物学及光学性质,同时探讨使用该种载体构建组织工程角膜上皮的可行性。 方法:本研究利用0.02%的EDTA去除失活羊膜组织的上皮细胞,并采用IV型胶原酶消化去除羊膜基质的纤维层及海绵层,从而获得羊膜致密层。比较从不同位置来源的胎儿面及胎盘面羊膜,选择合适的羊膜来源。以传统的完整羊膜(I...Purpose: Amniotic membranes (AM) are widely used as a corneal epithelial tissue carrier in reconstruction surgery. However, the engineered tissue transparency is low due to the translucent thick underlying AM stroma. To overcome this drawback, we developed an ultra-thin AM (UAM) by stripping away from the epithelial denuded AM (DAM) some of the stroma, and evaluated its biomaterial characteristics...学位:理学博士院系专业:医学院_生理学学号:2452013015432

    TNF induced RIP3-dependent NADH depletion

    肿瘤坏死因子(tumornecrosisfactor,TNF)能诱导L929细胞产生相互作用蛋白3(receptor-interactingprotein3,RIP3)依赖的程序性细胞坏死,并且在该过程中,胞内的线粒体产生的活性氧(reactiveoxygenspecies,ROS)会积聚,同时当RIP3的表达水平敲低时,胞内ROS的积聚也受到了抑制。但是RIP3如何影响ROS的具体机制仍不清楚。 因为ROS的产生主要在线粒体电子传递链上,而还原型辅酶Ⅰ(NADH)和还原型辅酶Ⅱ(NADPH)又是电子传递链的底物,RIP3是否能通过改变电子传递链上NADH或者NADPH的消耗来影响ROS。我...TNF (Tumor necrosis factor) can induce necrosis in L929 cells which is RIP3 dependent. ROS (reactive oxygen species) production increase during this process which is also RIP3 dependent, RIP3 expression knockdown inhibits the accumulation of ROS. But the mechanism of how RIP3 affect the ROS production is unknown. ROS is generated mostly through the ETC (electron transport chain) of mitochondria, ...学位:理学硕士院系专业:生命科学学院_细胞生物学学号:2162012115244

    随着经济全球化的推进和世界市场的建立,全球性的竞争日趋激烈。传统的“纵向一体化”的生产与经营模式无法敏捷响应复杂多变的市场,无法承受巨额的投资和较长的建设周期。供应链管理作为一种新型管理模式应运而生,在运作中强调以顾客为中心,注重提高对顾客需求的快速反应能力和创造最大的顾客价值,以先进的技术降低企业总成本,从而最终提升企业核心竞争力,提高利润率。在经济全球化驱动下,企业经营范围拓展到国外,所面临的供应链也由国内扩展到世界各国,形成全球供应链。全球供应链相比国内供应链更具复杂性和风险性,同时对提升企业核心竞争力也起到了更大的作用。本文从全球供应链管理的概念入手,分析企业国际化经营不同阶段的全球供...With the advance of economic globalization and the establishment of the world market, global competition has become increasingly fierce .Traditional production and business model has become increasingly slow and passive.

    随着城乡一体化建设加速发展,征地工作大范围进行,产生数量庞大的被征地农民群体。被征地农民处在城镇化的前沿,收入结构也随着身份的转变发生了变化。土地曾是农民赖以生存的生产生活资料,土地收益曾是农民最稳定的收入来源。失地以后,如何解决被征地农民的养老问题,使他们更好地融入城市生活,成为被征地农民社会保险政策的关键所在。解决好被征地农民社会养老问题,既是维护被征地农民切身利益的需要,也是建设服务型政府的题中之义。 本文通过对福州市被征地农民基本养老保险政策的实施现状进行调查研究,结合当地土地征用情况,详细阐述实施过程中在资金监管、制度设计、信息管理等方面存在的问题,并分别从政府主体、参保对象、制度...The rapid development of the integration of urban and rural construction has resulted in a large number of land-expropriated farmers.

    A Corpus-Based Analysis on Pragmatic Presuppositions in Advertising Texts

    广告在现实中起着价值引领的作用,是现代生活的重要组成部分。但强制性、灌输型的现代广告语篇常常使受众反感,而语用预设的恰当运用正好可以实现广告隐蔽而委婉的劝说作用,广告语言和预设理论的结合正是两者发展的需要,因此广告语篇的预设研究日益受到重视。目前的广告语篇研究视角多元,但以定性研究为主,普遍具有重复性和零散性,不够系统和深入;所采用的广告语料陈旧、零散,多以从网络、报刊、杂志等渠道收集的商业广告为主,具有较大的主观性和随意性;对广告受众理解的角度和预设使用不当的现象关注较少。 本文第一章扼要介绍了本文的研究背景和意义、研究内容和目标及章节结构,本文的语料库建设和研究方法是本章的重点。本文的语...As an integral part of modern life, advertisements have been playing the role of value guidance in reality.

    纵观国内外商业发展史,军人企业家成绩瞩目、广受关注,本文从战略角度出发,结合行为会计学观点,探究军人高管表现突出的原因。心理学大量研究表明,早期生活经历会对个体的性格、认知产生长期影响,进而作用于个体的决策过程。“高层梯队理论”指出,基于“有限理性”假设,高级管理人员独特的生活经历以及其在经历中所形成的心理特征,会影响公司的战略决策模型。 基于文献综述与理论回顾,本文选取从军经历为切入点,分析从军经历对高管风险偏好、企业竞争战略选择的影响。在得出初步结论后,进一步探讨高管从军经历与差异化战略的匹配对企业绩效的提升效果。本文逐一手工查阅高管简历,以具有从军经历的高管所任职的A股上市公司为研究对...In consideration of the commercial history both China and abroad, it is not difficult to find that managers with military experience have been creating an outstanding performance in company management.
