＜正＞The Steel Industry is very varied and *** International Iron and Steel Institute has since 1967 undertaken the task of building a network to share information and gather companies under a unique flag,the one of Steel *** manages to build global messages aimed at policy and stake holders. Working groups in projects are composed of representatives from Steel companies and discuss of important questions faced by Steel Industry in all domains. Studies help getting figures around the world,understand the challenges faced by the steel industry and prepare future global messages. Through efficient networking,the IISI wants to promote steel’s innovation and prepare an even brighter future for steel. Through projects in our Benchmarking,Technology and Environment Department and thanks to main committees on Technology,Environment and Safety,I want here to give concrete examples of how IISI go forward and innovates with all its members.

本文选题为“一种检测与预防SQL注入式攻击的查询标记方法”。该选题来源于以下实际背景：当前的数据库系统的安全正在受到与日俱增的未经许可的SQL注入式攻击的侵犯。科技日新月异,攻击手段也层出不穷。由于攻击者总是不断地寻找出新的攻击方式,因此现有的SQL注入攻击的保护方法总是不够完备。多年来,数据安全一直受到来自世界各地的攻击者的威胁。虽然数据安全的研究历来就有,但数据安全始终得不到完全保障的事实表明,当代研究者还是应该把数据库安全问题作为首要的研究对象。本文研究的目的是：应用“查询标记”的技术方法进行SQL注入式攻击的自动化检测和预防。本论文讨论了SQL注入式攻击的相关技术,如下：网络应用程序可以通过获取用户指令从而相应的通过SQL语句查询数据库信息。通过让SQL语句注入含有恶意代码的查询语句,可以轻而易举的伪装成普通用户的请求,进而进入数据库,这样攻击者就可以任意修改数据库内容,对数据安全造成巨大的威胁。如何防止以上情况的发生呢?研究人员注意到,SQL语句中有两种变量：数字和字符串。SQL标准规定：“字符串变量可以被单独引用,而数字不可以”。根据SQL注入式攻击的结构,攻击者必须在输入语句中输入至少包含一个单引号或者两个破折号的输入语句才能成功的侵入目标系统。也就是说,输入的攻击句中必须有至少一个字符。因此,攻击者并不能成功攻击一个只接受数字输入语句的目标系统。许多研究者提出的相应解决方法都依照此理论进行。然而,这些研究都把注意力放在以上理论上,而没有深入研究其他理论,因此是不全面的。现有的研究或多或少地包括一些实际应用的缺点和不足,比如缺少实际应用支持,不能全面检测到所有攻击范围。此外,研究人员也对预处理指令,输入语句检验,输出编码等在实际中的应用的进行了详实的讨论。然而,虽然有很多研究成果,但是基于上述常用理论所导致的不足也是显而易见的。因此,本文另辟蹊径,创新性地提出和以上方法不同的研究思路。它的理论思想是对于首次查询内容进行研究,以及对疑似注入攻击的查询和原始查询进行比对,检测SQL是否受到攻击者的注入攻击。通常,当用户输入验证时,SQL注入攻击者一定要在其中嵌入一个单引号,双破折号或两个单引号或双破折号,以完成一次成功的攻击。所有SQL注入的对象是数据库,之所以能成功攻击数据库,其缺陷不在于数据库服务器,或者是不够完整的授权体系。相反,它的缺陷取决于脚本的编写方式。换句话说,这种类型的攻击往往是程序员的错误,而不是SQL服务器错误的结果。我们所研究的核心问题就是要寻找一种方法,来检测用户所输入的验证是否加入了额外的用于SQL注入式攻击的语句结构。为了解决SQL注入式攻击带来的问题,许多学者提出了大量的解决方法和概念模型,然而,这些方法和模型大多是不完备的或者很难应用到具体情况的。所以本文基于以下事实来解决SQL注入式攻击的潜在问题：每个输入区域的输入内容受两个单引号限制,并且输入的单引号的数量必须是输入的字符串数量的两倍。本文的核心讨论内容之一：运用查询标记数量等于用户在查询时输入的字符串数量这一原理,标记查询内容。而本文中所谓的查询标记,是指把一个查询划分为不同部分的过程。标记的数量通过把一个查询中的单引号数除以二取得。当单引号的数量除以二除不尽时,那么此查询就被定义为语法错误,进而此次查询不能被数据库系统接受。本文的核心讨论内容之二：作为一个解决SQL注入式攻击的方法,本文提出了查询标记的注入攻击检测和预防机制模型,并根据此模型实现了两种具体的算法。第一个算法是通过单引号数量得到查询标记数量的程序算法。在这个算法中,查询中的标记数量等于查询的单引号数除以二。当单引号数为奇数,查询不能被执行。根据这一算法,标记的数量将与输入接受字符串的的数目相同。单引号数除以二,就可以获取标记的数量,因为查询的字符串输入受到一个在输入内容开头的单引号和一个在输入内容结尾的一个单引号的限制。第二种方法是注入攻击检测。注入检测算法标记实时查询用户输入内容,并对比此类标记获得的数量与原始查询内容获得的标记数量。该注入检测是从原始查询发起的或者查询包含用户输入的不同的标记数目。根据这一算法,注入攻击时也查询包含的双破折号。本文使用Java实现了上述两个算法,主要涉及了三大块内容：查询标记,标记宏表和注入检测。查询标记的功能是实现标记化查询功能。标记宏表的功能是创建一个记录原始查询取得的标记数和其他注入检测所需的信息文件夹并分类列好。标记宏表在应用程序运行时将信息保存并被加载到计算机内存。该注入攻击检测的宏比较了两种查询(原始查询和用户输入的实时查询)的标记数,并判定是否含有注入式攻击。为了测试本文提出的方法是否可行,特开发了一个学生成绩管理系统,以便模

In compartment fires (houses, buildings, underground, warehouse, etc.), smokes are a major dan- ger during firemen intervention. Most of the time, they are at high temperature (>800?C) and they flow everywhere through many kinds of ducts, which leads to the propagation of the combustion by the creation other fires in places which may be far away from the initial fire. In this paper, we present a new approach of the problem, which allows to better follow the fire behavior and especially to detect the dangers that may appear and endanger firefighters. This approach consists in a mathematical analysis based on the comparison of moving averages centered in the past, calculated on the temperature recordings of the smokes. As a consequence, this method may allow to improve decision support in real time and therefore to improve the security and the efficiency of firefighters in their operations against that kind of fires.

Intradural disc herniation is rare and often diagnosed during surgery. We present two patients with the disease, one with an intra-arachnoid type, the other with an extra-arachnoid location. The teaching point of those cases is that this very frequent pathology can take a variety of forms, depending on the structures that are infiltrated. The key point in correctly diagnosing the intradural disc herniation is to look at the angle between the fragment and the dura. Is it pushing it (as in the usual disc herniation), embedded in it (those with the extra-arachnoid type) or does it go through to fall into the CSF (In the intra-arachnoid type)? It could be diagnosed on MRI preoperatively. Contrary to many published cases of intradural disc herniation, the two patients could be managed non-surgically.
