外包过渡中的管理控制问题探讨

外包过渡是介于外包关系建立与实施之间的一个关键环节,顺利的外包过渡对外包项目持续、有效的后续管理关系重大.着重对外包过渡中的衔接问题、整合机制、管理架构、管理者安排,以及应遵守的程序进行了探讨,这对成功的外包实践有着现实的指导意义.     

整体经济效益最优控制方法

本文提出了整体经济效益最优的动静态耦合的优化控制一体化方法，它在传统的两级优化控制结构中加入一层协调级，能有效地克服以往优化级撇开控制能量代价不计的缺陷。特别是一体化系统通过调级从控制层向优化层引入反馈，使得由于过程自身动态因素对操作点的制约，能有效地通知到优化层，避免了优化的盲目性和片面性。各个层次之间通过公用数据库交换数据，使它们的决策与目前生产过程的实际情况密切联系。

Studied on a novel human keratinocyte membrane delivery system in vitro

The culture of keratinocytes on flexible membranes has been proposed as a means to simplify, accelerate and improve the efficiency with which proliferating cells are delivered to full thickness or non-healing skin defects. The purpose of this article was to study the ability of chitosan-gelatin manbranes to facilitate the growth of human keratinocytes. The membranes with different chitosan contents were studied. The surface properties of chitosan-gelatin membranes were investigate by SEM, and water contact angle test. The mechanical property of the membranes was tested. Data implied that gelatin could make the membranes more flexible and hydrophilic than chitosan membranes, which may regulate the seeded cells behavior. Loading human keratinocytes on chitosan-gelatin membranes, cells attachment, spread, and growth were investigated by light microscopy, SEM, and MTT test. The results suggested that the adhesion and proliferation of keratinocytes seeded on chitosan-gelatin membranes were same as on tissue culture plate, in which gelatin could modify the interaction between keratinocytes and chitosan membranes. Therefore, chitosan-gelatin membrane is a good candidate for keratinocytes delivery system.
