当代的个人安全结构可以按类别进行汇集。传统的个人认证系统都是建立在知识(密码、用户名等)或者物理标识(身份证、护照、学生证等)的基础上而不能满足许多现代应用对于严格的安全性能的需求。这些应用程序一般利用计算机网络(因特网、局域网等)影响很大一部分人群,并管制具有经济价值且涉及个人隐私的工作(电子商业、电子银行、电子政务等)。建立在生物特征识别方法基础上的认证系统是传统技术地较好改进,在其中我应用了生理和行为上的特征(指纹、面容、签名等)。这些系统更加可靠(生物统计数据不会丢失、遗忘或者被猜想到),也更容易使用(没有什么要记住或携带)。因此,生物辨识系统的使用变得越来越普遍。例如,联合国宣布,到2014年,所有国家都必须使用生物特征识别系统来替代他们现在的护照安全结构。在本文中,我我将集中在生物辨识系统上。什么是生物特征识别技术?它是如何运行的?它能如何为安全性能服务?我会使用应用实例进行详细说明。应该如何将生物特征识别技术集成到其它安全系统?有什么漏洞、威胁和攻击性?这是这篇论文研究的主要方向。因此我将主要介绍加密系统的使用以及其与生物特征识别系统的集成,我还会说明将二者结合的办法。我还会阐述MD5and SHA-1算法,突出MD5&SHA-1加密工具的使用,以从生物统计数据中得出MD5and SHA-1哈希键。这些数据是通过使用ROI抽取镜像,即指从手指或虹膜中提取镜像：它是如何集中在区域点以提取镜像。像指纹镜像特微点一样,虹膜也是规格化的。这些生物特征将被转化为计算机语言。

Assessment on self-care, mobility and social function of children with spina bifida in Turkey

引用

Neural Regeneration Research 2014年第12期9卷 1234-1240页

作者： Hulya Sirzai Beril Dogu Selamet Demir Figen yilmaz Banu Kuran Ankara Physical Medicine and Rehabilitation Education and Research Hospital Department of Physical Medicine and Rehabilitation Sisli Etfal Education and Research Hospital

The aim of the study was to investigate the functional performance in children with spina bifida, using the Pediatric Evaluation of Disability Inventory （PEDI） to look into capacity of twen- ty-eight children with spina bifida with lesions at different levels in different dimensions of self- care, mobility and social function. Mean age of the patients was 3.5 ± 2.3 （1-10） years. In the muscle test carried out, 13 patients （44.8%） had no movements including pelvic elevation in lower extremity muscles and they were at level 5. Sixteen patients （54%） were non-ambulatory according to the Hoofer ambulation classification. Raw and scale scores in the self-care, mobil- ity and social function domains both in the functional skill scale and in the caregiver scale were found to be lower compared to the data of the normal population. A statistically significant correlation was observed in the self-care values of the Functional Skills Scales and the Caregiver Assistance Scale measurements, which was positive for age and negative for Functional Ambu- lation Scale and muscle test （P 〈 0.05）. A positive relation was found between the Functional Skills Scales-mobility area and age while a negative relation was observed between Functional Ambulation Scale and muscle test （P 〈 0.005）. A negative relation was also found between Care- giver Assistance Scale-mobility and Functional Ambulation Scale and muscle test （P 〈 0.005）. In our study, the functional performance of the children was found to be low. Low-level lesions, encouraging muscular strength and independence in mobility are all very important factors for functional independence.

AIM： To investigate whether single-dose intravitreal injections of bevacizumab and ranibizumab transfer into milk. METHODS： This study included lactating 12 sheep and a single 3-month old suckling lamb of each sheep. Two groups consisting of 6 sheep and their lambs were constituted; the ranibizumab group and the bevacizumab group before the administration of intravitreal injections, blood and milk samples were obtained from all sheep and, following the injections, blood and milk samples of all sheep and blood samples of all lambs were collected at regular time points. Serum and milk concentrations of bevacizumab and ranibizumab were measured using an enzyme-linked immunosorbent assay（ELISA） kit. The limit of determination was 0.9 ng/m L for bevacizumab and 0.62 ng/m L for ***： At 6h after intravitreal injections, bevacizumab concentration was above the limit of determination in the blood of all sheep. At 3wk, when the study was terminated, bevacizumab concentrations were high in 4 sheep. Even though bevacizumab concentrations in milk showed fluctuations, the drug transferred into the milk of all sheep at detectable concentrations. Ranibizumab drug concentrations in the blood and milk of sheep and those in the blood of lambs were below the limit of determination by the ELISA ***： This sheep model study demonstrate that intravitreal injection of ranibizumab, which did not transfer into the milk of sheep and suckling lambs, is safer than bevacizumab during lactation period.

Hepatic artery reconstruction(HAR)is the most valuable step in correcting graft and recipient survival after liver transplantation(LT).Hepatic artery thrombosis(HAT)in immediate postoperative period may lead to fatal *** allograft is partial in a living donor liver transplantation(LDLT),and HAR is technically much more difficult than deceased donor liver transplantation(DDLT).The likelihood of HAT in LDLT is higher due to the narrower diameters of arterial vessels.

The serious problems caused by extensive usage of petroleum-based plastic materials led to investigating the comprehensive studies and developing active food packaging *** if the chitosan-based films are considered an attractive source,they exhibit some practical difficulties in developing active food packaging ***,Ficus carica Linn leaves extract(FLE),with the features of its cheapness,easy accessibility and superoxide anion radical scavenging activity,was incorporated into chitosan(CS)film at various concentrations(2%-6%w/w).To the best of our knowledge,this was the first time that FLE was utilized as a bioactive substance incorporated into chitosan films to develop eco-friendly,biodegradable,active food packaging *** results obtained revealed that FLE incorporation into chitosan films significantly improved the swelling,water solubility and opacity of neat chitosan *** and morphological analysis indicated that the films produced exhibited smooth structure with homogenous dispersion of *** mechanically,the addition of FLE resulted in a significant reduction in tensile strength while the elasticity of the films was ***,the antioxidant and biodegradability properties of neat chitosan films were enhanced *** was concluded that CS-FLE films appeared to be a capable and enhanced option for synthetic polymer-based food packaging *** on the analyses performed,further studies are suggested on the packaging application for various foods and to evaluate the possible interaction of packaging film materials with the compounds of the food products,to avoid possible negative effects.
