E-Learning becomes more important to companies, government and common people due to the development in information technology. They use e-Learning not only for training employees but also for acquiring common knowledge. However, planless development in e-Learning introduces some problems. For example, in public sectors, there are many similar platforms and courses, which makes part of investment become a waste and unnecessary.

数位学习随著资讯科技的发展及普及渐渐受到政府及产业的重视，不管是企业内部的教育训练、一般民众或是公务员的再进修，采用数位学习的比例都不断提高，然而，没有经过整体规划的发展却会带来一些问题，像是企业可能必须面对内部多个分散的数位学习资源，台湾的公部门数位学习网站也因为没有经过整体规划造成各单位独自发展，产生许多重复的课程以及目标、功能类似的平台，造成资源浪费。

Objective To use an ischemical reperfusion injury rat model by pulsinelli-4-VO andobserve the changes of the expression of Glu, N-methy-D-asparagic acidreceptor subunits NR_1 and NR_(2B) and ability of learning and memory after procerebrum ischemic reperfusion injury, and approach the pathogenesy of learning andmemory disorder induced by ischemic reperfusion injury, and the intervention ofginsenoside Rg_2 on the learning and memory disorder after procerebrumischemic reperfusion injury.

Objective: Mannose-binding lectin is a plasma protein belonging to the family of collectins, composed of a N-terminal segment, helical coiled-coil hinge region, collagen-like stalk domain., and globular type C lectin domain or carbohydrate recognition domain. Full MBL biological function requires assembly to at least the tetrameric level.

目的：甘露聚糖结合凝集素(Mannose-binding lectin， MBL)是属于C型凝集素家庭胶原凝集素的一种血清蛋白，包括N末端区（N-terminal segment）、螺旋铰链区（helical coiled-coil hinge region）、胶原样区（collagen-like region，CRL）及球形C型凝集素区或糖识别区（carbohydrate recognition domain ，CRD）等4部分结构区域，四个亚单位的MBL形成有功能的多聚体。

This compensation circuit can make the stability of the LDO linear regulator undependent on the effect of load capacitor's equivalent serial resistance, and it also makes the unit gain frequency bandwidth change slightly when the load is varying, thus greatly improving the performance of transient response, Furthermore, on the basis of dynamic frequency compensation, an overcurrent protection circuit is designed.

文章针对LDO稳定性的问题，提出了一种内部动态频率补偿电路，使LDO线性稳压器的稳定性不受负载电容的等效串联电阻的影响，其单位增益带宽也不随负载电流变化而改变，大大提高了瞬态响应特性；采用Hynix 0.5μm CMOS工艺模型对电路进行仿真；此外，该电路在实现动态频率补偿的基础上又加入了系统的过流保护功能，当负载电流大于限制电流时，LDO不能正常工作；当负载电流小于限制电流时，又自动恢复到正常工作状态。

It is suggested that the sodium selenite might be effective for inducing apoptosis in cultured cortical neurons, and the relavant changes in expression of several genes might underly the mechanisms which initiate and maintain the apoptptic processes.

硒是人和动物体必需的微量元素，已检出25余种含硒蛋白及亚单位，其中有些在脑组织中分布广泛，并且在调节神经元和胶质细胞的生长、发育、和功能维持等方面具有重要的作用。

The::unwired 的::无线 had a look on pre-production unit and said that the Hermes is really small, close to the HTC Wizard, a little bit longer and thicker than the HTC Magician/Prophet but it features a slide-out keyboard, which is way better than the Wizard keyboard (pretty similar to the Universal keyboard) and not to forget it features UMTS and HSDPA.

有期待预生产的单位和说，爱马仕确实是小，接近宏达向导，有点长，厚度比宏达魔术师/先知但它采用了滑出式键盘，这是方法优于精灵键盘和不能忘记它的功能UMTS和

All functions of the placing boom ,the concerte pumu and the drive motor can be carried out by means of an electric cable remotecontrol or interchangeably ,via radio control .in the case of possible failure of the remotecontrol ,one can run the equipment by means of direct manual operation from the vehicle ;the controls are arranged for this purpose .the unit can be cleaned easily and quickly .the accessory equipment , the chamber valve ,solves the promble of residual concrete in the concerte pump .we have thought of all those things that are so important for daily use of the pump ,such as the large lockable compartment for tools and accessorise ,the C-type connection for filling up water ,work searchlights ,operator's cab ,wooden chocks .

的所有功能将蓬勃发展，对混凝土pumu和驱动马达可以进行通过一个电缆remotecontrol或互换，通过无线电控制。在可能的情况下失败的remotecontrol ，人们可以在设备运行的方式直接手动操作的车辆；控件安排用于这一目的。单位易于清理迅速。辅助设备，分庭阀，解决了promble残余混凝土在混凝土泵。我们认为所有这些事情这是非常重要的日常使用的泵，如大型上锁室的工具和配饰， C型方面填补了水，工作探照灯，运营了驾驶室，木制

They encompass the following broad bands of biological roles:(1) basic structural units of cellular membranes and cytologically distinct subcellular bodies such as chloroplasts and mitochondria;(2) compartmentalizing units for metabolically active proteins localized in membranes;(3) a store of chemical energy and carbon skeletons; and (4) primary transport systems of nonpolar material through biological fluids.
