Design and Implementation of Network Security System Based on Multi-Protocol Label Switch [PDF]
VPN(虚拟专用网络)实例间隔离性出色是MPLS(多协议标签交换)网络的一个重要特点,也正是由于这一优势,在最近几年,不同企业甚至不同行业间,均广泛采用这一网络。然而,VPN实例内的安全性问题却没有进行充分的考虑。当前阶段中,通常将安全设备安装在MPLSVPN的网络边缘处,也就是CE(用户边缘)设备部位,以达到保护的效果。然而,在网络的分支机构比较复杂的情况下,CE设备也通常会随之增加,在这种情况下,利用这一方式通常需要支付较高的成本,而且不利于整网的实用性,同时,在后续维护和管理中也会带来较大的困难 ...

The impacts of coastal defense structures on rocky intertidal community in Yangtze River Delta [PDF]
长江三角洲是长江、黄河以及在此区域的其他河流的活动形成的冲积平原。末次冰期(LastGlacialMaximum,LGM)以后的一万年以来,长江三角洲在海陆交互作用的影响下逐渐扩展。位于长江三角洲地带的近900km的江苏沿岸海岸线除约40km的基岩海岸以外,均为不适宜岩相潮间带生物大量聚集的淤泥质平原海岸。近年来随着中国沿海经济的飞速发展,对土地需求的不断增加,越来越多的沿岸防护建筑正在被修建,成为我国沿岸的“海上长城”。这些沿岸防护建筑显著改变了江苏沿岸的滩涂景观,可能对潮间带群落造成严重影响 ...

A survey of protection consciousness on sharp instrument injury of practcing nursing students
[目的]了解实习护生被锐器损伤的情况,为采取职业防护措施提供科学依据。[方法]采用问卷法调查183名实习护生锐器损伤的发生率和防护行为。[结果]97.3%的实习护生有锐器伤的经历,其中锐器损伤和安瓿玻璃割伤占首位。实习护生缺乏锐器伤的防护意识。[结论]实习护生要充分认识到锐器伤防护的重要性,增强锐器伤的防护意识,同时要加大职业防护的管理,以减少锐器伤的危害。
