  • [学位] H医院护理人员流失问题及对策研究
    当今医疗体制改革步伐在不断推进当中,随之而来的是诸如医院这样的医疗机构外部环境逐步改变。单一结构的市场格局转变为多元结构,21世纪人力资源优势将成为医院的核心竞争力。各个医院核心竞争力的体现形式,从单一的资本与产品转变为医院之间在进行人力资源的竞争。哪家企业想要在经济发展的竞争中占有相当数量的主动权,那么这样的企业必须拥有更多的高质量人力资源。对比各个医院之间的差距不难发现,差距的点就在于:人员。要想在激烈的医院竞争中成为最后的赢家,这样的医院就需要具备招募、留用、培养以及激励员工的能力。如今的医疗行业竞争是与日俱增的,医院要拥有相当数量的专业医疗技术人员,才能满足向百姓提供质良、安全、有效并且价格低廉的医疗服务。众所周知三分治疗七分护理,由此可知护理人员在整个医疗团队中的重要性不言而喻。医院想要稳步的提升护理质量,最大程度的减少医疗隐患,从而达到保障患者生命安全的目的,就必须具备足够的护理人员。 本文基于H医院的实际状况,查阅了国内、国外的相关理论文献,运用了多种研究方法相结合的方式,通过实际数据多层次的分析H医院护理人员流失的问题。论文运用问卷调查法、离职员工个别访谈法、在职员工个别访谈法。调查统计出的数据归纳总结为内部、外部以及个体原因这三个方面,进而总结出H医院护理人员大量流失的问题点,以及导致这种离职意向的各种原因。基于研究数据从以下六个方面对护理人员流失问题应对改正,包括:加大行政管理力度、改善薪酬与福利、集中人事管理权限、加强H医院文化建设、重视护理人员职业生涯规划、加强宣传提高护理人员社会地位。 最后,概括了本研究的结论,并提出了本次研究所存在的局限性以及不足之处,为问题的深入研究指出了一定的方向性。本研究为H医院护理管理给予了指导意义,并在人员流失问题上提供了一定的实践与理论意义,在同类型医院解决护理人员流失问题上给予参考。

  • [期刊] A Numerical Way of Determining the Boundaries of a System of Bodies in a Three-Dimensional Medium by Means of Integral Equations
    The propagation of acoustic waves in a three-dimensional medium with several local inhomogeneities of different shapes is analyzed. Solving the inverse problem of determining boundaries of local inhomogeneities from measurements of a field in a bounded receivers location domain is reduced to a system of integral equations. An iteration approach to solving the inverse problem is proposed, and the results from numerical experiments are presented.
  • [期刊] Salt rejection in flow-between capacitive deionization devices
    Desalination technologies can increase potable water supplies worldwide. One possible approach, capacitive deionization (CDI), could prove optimal for brackish water treatment. At present, CDI development has largely focused on increasing salt adsorption capacity and desalination rates of materials and devices. In addition to these metrics, ultimately, optimizing salt rejection and throughput will be essential. In this work, we present a framework for the design of flow-between CDI cells for maximum salt rejection. We developed a model that is dependent on device specific parameters (system volume, flow rate, inlet and outlet water quality), to generalize the design of a cell for any given requirement. We showed that decreasing the advection-diffusion Peclet number and increasing the aspect ratio of the electrode compared to the channel space yield the highest salt rejection. In addition, tuning the cycle frequency time for salt rejection instead of complete electrode charging can yield faster water production rates and optimal salt rejection. These modeling results were validated through experimental prototypes that made use of vertically-aligned carbon nanotube (VA-CNT) electrodes. This framework to maximize salt rejection can be extended to a multitude of porous electrodes used in flow-between CDI devices.

    1. Diana, the Nutrition Division of Symrise, reaches a turnover of €600 million and therefore accounts for about 20 percent of the Symrise turnover as a whole (circa €3 billion in 2017). Diana is organized around three business units - Diana Food, Diana Pet Food and Diana Aqua. 2. Diana recently opened a new food ingredients facility in Banks Crossing, Georgia, US. This site, operated by Diana Food, is dedicated to chicken-based solutions from humanely-raised birds. The plant meets high animal welfare standards and will include a range of chicken fat, broth and powder products.

  • [专利] Compositions and coatings with non-chrome corrosion inhibitor particles
    (EP3197960) Compositions are described for protecting a metal surface against corrosion. The composition includes a corrosion-inhibiting particle. The corrosion inhibiting particle may be usable in an epoxy resin-based coating or an olefin resin-based coating. The particle may include a core and a protectant. The core may include a water soluble corrosion inhibitor. The protectant may be disposed on at least a portion of a surface of the core and may be covalently or ionically bonded to a thiol group of the corrosion inhibitor. The protectant may be configured to reduce reaction between the core and the epoxy resin or the olefin resin. (From US2016090486 A1)
  • [期刊] XRF measurements of tin, copper and zinc in antifouling paints coated on leisure boats
    Tributyltin (TBT) and other organotin compounds have been restricted for use on leisure boats since 1989 in the EU. Nonetheless, release of TBT is observed from leisure boats during hull maintenance work, such as pressure hosing. In this work, we used a handheld X-ray Fluorescence analyser (XRF) calibrated for antifouling paint matrixes to measure tin, copper and zinc in antifouling paints coated on leisure boats in Sweden. Our results show that over 10% of the leisure boats (n = 686) contain >400 μg/cm2 of tin in their antifouling coatings. For comparison, one layer (40 μm dry film) of a TBT-paint equals ≈ 800 μg Sn/cm2. To our knowledge, tin has never been used in other forms than organotin (OT) in antifouling paints. Thus, even though the XRF analysis does not provide any information on the speciation of tin, the high concentrations indicate that these leisure boats still have OT coatings present on their hull. On several leisure boats we performed additional XRF measurements by progressively scraping off the top coatings and analysing each underlying layer. The XRF data show that when tin is detected, it is most likely present in coatings close to the hull with several layers of other coatings on top. Thus, leaching of OT compounds from the hull into the water is presumed to be negligible. The risk for environmental impacts arises during maintenance work such as scraping, blasting and high pressure hosing activities. The data also show that many boat owners apply excessive paint layers when following paint manufacturers recommendations. Moreover, high loads of copper were detected even on boats sailing in freshwater, despite the more than 20 year old ban, which poses an environmental risk that has not been addressed until now.
