Yixiang Jiang, Jie Qian, Chengting Zhang
At present, the safety protection measures of the industrial control system roughly cover the following aspects, respectively: the establishment of the safety management system of the industrial control system, the safety evaluation of the industrial control system, the standardization of the operation behaviour of the industrial control system, and the architecture design of the safety industrial control system. In addition, there is no professional industrial control system network security technology products, can protect the network security of industrial control system. A security threat detection system based on multi-classification support vector machine (SVM) is designed to attack the security of industrial control network. By using the classic CIDF intrusion detection system, the overall framework of the security threat detection system is designed to become a model structure integrating data preprocessing, data information extraction, and security threat detection. Then a detection model based on multi-classification support vector machine (SVM) is designed by combining the security threat attack with the characteristics of SVM. Under the management of Linux platform and combined with libsvm software, the multi-classification SVM detection model is built and tested. In this paper, a multi-svm based access control defence model and security threat detection system are designed to deal with various attacks on industrial control networks, which has a positive significance for the development of industrial control information security.
目前,工业控制系统的安全保护措施大致涵盖了以下几个方面,分别是建立工业控制系统的安全管理体系,对工业控制系统进行安全评价,对工业控制系统的运行行为进行规范,对安全工业控制系统进行体系结构设计。另外,目前还没有专业的工控系统网络安全技术产品,能够保障工控系统的网络安全。针对工业控制网络的安全问题,设计了一种基于多分类支持向量机的安全威胁检测系统。利用经典的CIDF入侵检测系统,设计了安全威胁检测系统的总体框架,成为集数据预处理、数据信息提取、安全威胁检测为一体的模型结构。然后结合安全威胁攻击和支持向量机的特点,设计了基于多分类支持向量机的检测模型。在Linux平台管理下,结合libsvm软件,构建了多分类SVM检测模型并进行了测试。本文设计了一种基于多支持向量机的访问控制防御模型和安全威胁检测系统,以应对工业控制网络的各种攻击,对工业控制信息安全的发展具有积极意义。

Research on online shopping user behavior based on information cascade 基于信息级联的网上购物用户行为研究
Mingsheng Zhao, Yueshu Zhao
Information cascades are common in real social life, because of information cascades can lead to blind follow-up by users, it is easy to have a bad impact on society. This paper proposes a new method to research on the online shopping user behavior based on information cascades. By collecting date from jd between October 1, 2019 and September 30, 2020, this paper constructs unbalanced panel data, empirically tests the information cascade effect in online shopping users’ Behavior, and study the mixed impact of information cascade and online word-of-mouth on users’ shopping behavior. The results show that the relative popularity of goods has a significant impact on its sales, showing an obvious information cascade effect. The number of comments has no impact on the sales volume of high ranked goods, but has a positive and significant impact on the sales volume of low ranked goods, and the user score has no impact on the sales volume of goods. The law of demand is still valid for high ranked commodity sales. For the lower ranked products, the price represents the quality information of the products and has a positive impact on the sales volume.
信息级联在现实社会生活中很常见,由于信息级联会导致用户盲目跟进,很容易对社会造成不良影响。本文提出了一种基于信息级联的在线购物用户行为研究方法。本文通过收集京东2019年10月1日至2020年9月30日的数据,构建非平衡面板数据,实证检验网络购物用户行为中的信息级联效应,研究信息级联和网络口碑对用户购物行为的混合影响。结果表明,商品的相对受欢迎程度对其销售额有显著影响,呈现出明显的信息级联效应。评论数对排名高的商品的销量没有影响,但对排名低的商品的销量有正向显著的影响,用户评分对商品的销量没有影响。需求法则对于排名靠前的商品销售仍然有效。对于排名较低的产品,价格代表了产品的质量信息,对销量有正向影响。

Rui Wang, Yaguang Xu
In order to improve the security of low-latency cluster dispatching communication network nodes, this paper proposes a security situation assessment method of low-latency cluster dispatching communication network nodes based on grey relational model. The security situation assessment model of low-delay cluster scheduling communication network nodes is constructed, and the comprehensive risk index is introduced as the three-layer assessment index of low-delay cluster scheduling communication network nodes. Based on the analysis of load loss probability and expected response characteristics of insufficient packet loss load in communication transmission, the reliability index calculation system of low-delay cluster scheduling communication network node scheduling is established. By introducing expected load reduction parameters, the frequency characteristics of node scheduling security in low-delay cluster scheduling communication network are monitored. Based on the average sustained risk index evaluation of load reduction, the security permission conditions of node scheduling in low-delay cluster scheduling communication network are established. The network transmission load control is carried out by using grey correlation scheduling model. The node control model of low-delay cluster scheduling communication network is constructed by combining risk assessment and load parameter detection. The learning control of node security situation assessment is realized by using Cyber-net and unsupervised learning methods. The node security situation assessment of low-delay cluster scheduling communication network nodes is realized through access and decentralized scheduling. Tests show that this method has high accuracy in evaluating the security situation of nodes in low-delay cluster dispatching communication networks, and has strong completeness and reliability in grid-connected control of communication networks.

Computer Assisted Efficiency Evaluation of Scientific and Technological Achievements Transformation in Guangdong Province Using DEA Measurement Model 基于DEA测度模型的广东省科技成果转化效率计算机辅助评价
Jundong Fang, Zongbin Jiang, Zeqiong Xie
The conversion efficiency of scientific and technological achievements in China's universities is relatively low. Analysis and evaluation of the conversion efficiency of scientific and technological achievements in universities can find problems and propose suggestions for improvement. This article establishes a model for evaluating the conversion efficiency of scientific and technological achievements in universities based on the DEA method, and analyzes 42 universities in Guangdong Province as cases. The research results show that the efficiency evaluation model for the transformation of scientific and technological achievements of universities is an effective DEA efficiency measurement model. The overall efficiency of the transformation of scientific and technological achievements of universities in Guangdong Province is not high. Only 7 of 42 universities are DEA effective. The average pure technical efficiency of 211 universities is 0.935, which is higher than the non-211 universities of 0.584, but the scale efficiency of 42 universities is lower than 0.5. In addition, the transformation of scientific and technological achievements in universities in Guangdong Province has problems of redundant investment in R&D personnel and insufficient income from technology transfer.
中国高校科技成果转化效率相对较低。对高校科技成果转化效率进行分析和评价,可以发现问题,提出改进建议。本文建立了基于DEA方法的高校科技成果转化效率评价模型,并以广东省42所高校为例进行了分析。研究结果表明,高校科技成果转化效率评价模型是一种有效的DEA效率测度模型。广东省高校科技成果转化的整体效率不高。42所大学中只有7所是DEA有效的。211所高校的平均纯技术效率为0.935,高于非211所高校的0.584,但42所高校的规模效率低于0.5。此外,广东省高校科技成果转化还存在研发人员投入过多、技术转移收益不足等问题。

An Analysis on Participatory Teaching Mode Used in IT-based Computer Course in Private Colleges and Universities 民办高校计算机信息化课程参与式教学模式分析
Juan Wang
Under the environment of education informatization, the students of private colleges and universities lack the knowledge of computer application technology, and the traditional teaching methods can't meet the needs of the current society. The participatory teaching mode of "online and offline education" was introduced into the teaching of computer application technology. First, the curriculum resources are carefully redesigned, such as teaching courseware, videos, case library, homework library, etc. Second, the big data analysis technology is used to obtain the students' learning situation in time. Finally, problem oriented and project oriented teaching and learning mode is introduced by the “Internet plus” student innovation and entrepreneurship competition platform to promote the innovation ability. The experimental results show that the participatory teaching mode is better than the traditional mode.
在教育信息化的环境下,民办高校学生缺乏计算机应用技术知识,传统的教学方法已不能满足当前社会的需要。将“线上+线下”的参与式教学模式引入计算机应用技术的教学中。首先,精心设计课程资源,如教学课件、视频、案例库、作业库等。其次,利用大数据分析技术,及时获取学生的学习情况。最后,通过“互联网+”学生创新创业大赛平台,引入以问题为导向、以项目为导向的教学模式,促进学生的创新能力。实验结果表明,参与式教学模式优于传统教学模式。
