Results The rate of consistent condom use each time among prostitutes was 13.64%; the rate of consistent condom use each time among STD clinic attenders when having sex with nonmarital sex partners was 5.05%; the rate of consistent condom use each time among gays having anal sexes in recent six months was 27.66%.

结果 暗娼坚持每次使用安全套者占。13.64%；性病门诊就诊者与非婚性伴发生性行为时坚持每次使用安全套者占5.05%；男性同性恋者最近6个月与性伴有肛交性行为每次都使用安全套者占27.66%。

Safety period contraception: New wedding day because the excitement of sexual life, the oviposit pattern with threw into confusion regular, easy happening additional oviposit, because this is safe period also insecure.

安全期避孕法：新婚期由于性生活的兴奋，打乱了正常的排卵规律，易发生额外排卵，因此安全期亦不安全。

1Cr5Mo, 12CrlMoV and 20# are three types of pearlitic heat resistant steel and widely used for high temperature tubes in petro-chemical industry, so their safety assessments are necessary for the sake of operation safety in high temperature cond.

The invention discloses a software security ensuring method based on program internal behavior monitoring which comprises,(1) the language code analyzer analyzing the program control stream, adding description control stream transformation code, adding assisting protection function for the program, then compiling into performable program,(2) transferring the treated program to a program charging device, determining whether the current program has a protection function,(3) submitting operation system the protection information of the progress and setting the program progress protection sign to TURE,(4) the operation system kernel determining the progress protection sign, go to step 7 if the result is FALSE,(5) the operation system kernel examining the progress control stream conversion consistency,(6) continuing the progress,(7) finishing.

本发明公开了一种基于程序内部行为监控的软件安全保障的方法，其步骤是：1。语言代码分析器分析程序的控制流，并添加描述控制流转换代码，添加程序的协助保护功能，然后编译成可执行程序；2。处理过的程序递交给程序加载器，判断当前程序是否具有保护功能，如果有则加载适当的运行环境，否则转到4；3。向操作系统递交该进程的保护信息并设置该程序进程的保护标志为真；4。操作系统内核一旦获得控制权利，则判断进程的保护标志，如果为假转到7；5。操作系统内核检查该进程控制流转换的一致性，如果不一致，发出安全警告，并杀死进程，转到7；6。继续运行进程；7。结束。本发明的显著优点是提高了安全保障方法的精确性和通用性。

Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。

A distributed secure clustering protocol is proposed, in which the secure network initialization, random number broadcast from the base station and one-way hash chain are used to achieve the resiliency against possible attacks including node personating, cluster-head occupying, malicious cluster-member recruiting and multiple cluster-membership attacks.

针对成簇协议所面临的各种安全威胁，提出了一种分布式安全成簇协议，通过网络安全初始化、可信基站的随机数广播和单向密钥链技术来有效地抵御节点伪装和簇首占据攻击、簇成员恶意征募攻击和多重簇成员身份攻击。

Risk and maneuverability analysis on engineering design is widely used to conduct security appraisal abroad. The potential risks might be caused by technical parameter deviation, failure and faulty operation of facilities and pipelines in the system were normally analyzed along with the reason why deviation and faulty operation occurred. The acceptable risk was then appraised according to the results, reasons and designed protective facilities. Later, the security countermeasures and solutions were brought forward purposively to further modify and refurbish the security design and operation management.

国外广泛应用危险与可操作性分析对工程设计进行安全评价，分析系统中装置、设备、管道的个别部分工艺参数偏离、故障或误操作引起的潜在危险，分析偏离、故障出现的原因，根据后果、原因和已设计的保护装置，评估可接受的风险，并有针对性地提出安全对策和措施，用以指导修改、完善工程的安全设计和操作管理。

this paper exhaustivly introduced the total course of implementing the secure information passageway based on ssl by internet information service on windows 2003 server,including the configuration of dns,active directory and ca, the requestion, installation and configuration of web server_end certificate and client_end certificate, the obtaining and installation of certificate chain etc.

本文详细介绍了如何在 windows 2003 server上用 iis服务器搭建一条基于ssl的信息安全通道的全部过程，其中包括对dns，active directory以及ca服务的配置，web服务器端证书和客户端证书的申请、安装以及配置，证书链的获取与安装等内容，简述了基于ssl的信息安全通道的原理及应用，阐明了为什么要使用信息安全通道来传输信息，并且提出了iis服务器上高于128位加密的实验性方案。

Active attack cryptanalysis based and fully scalable FGS encryption algorithm Aimed to the weakness of the current selective encryption algorithms in the sense of cryptanalysis, we design a active spacial—temporal correlation attack scheme and propose a both encryption strategies on base-layer and enhancement-layer. Not only the general FGS stream encryption is dealt with but also the case of FGST (fine granularity sealable temporal) is also well addressed.
