Interpretation of Information Security and Data Privacy Protection According to the Data Use During the Epidemic

COVID-19 has swept the whole our country and the world in the beginning of 2020.31 provinces and municipalities across the country have launched the first-level response to major public health emergencies since January 24,and China has carried out intensive epidemic control.It is critical for effectively responding to COVID-19 to collect,collate and analyze people’s personal data.What’s more,obtaining identity information,travel records and health information of confirmed cases,suspected cases and close contacts has become a crucial step in epidemic investigation.All regions have made full use of big data to carry out personnel screening,travel records analysis and other related work in epidemic prevention and control,effectively improving the efficiency of epidemic prevention and control.However,data leakage,personnel privacy data exposure,and personal attack frequently occurred in the process of personnel travel records analysis and epidemic prevention and control.It even happened in the WeChat group to forward a person’s name,phone number,address,ID number and other sensitive information.It brought discrimination,telephone and SMS harassment to the parties,which caused great harm to individuals.Based on these,lack of information security and data security awareness and other issues were exposed.Therefore,while big data has been widely concerned and applied,attention should be paid to protecting personal privacy.It is urgent to pay more attention to data privacy and information security in order to effectively protect the legitimate rights of the people.Therefore,measures can be taken to achieve this goal,such as improving the relevant legal system,strengthening technical means to enhance the supervision and management of information security and data protection.

Modeling and Simulation of Low Rate of Denial of Service Attacks

The low-rate denial of service attack is more applicable to the network in recent years as a means of attack, which is different from the traditional field type DoS attacks at the network end system or network using adaptive mechanisms exist loopholes flow through the low-rate periodic attacks on the implementation of high-efficiency attacked by an intruder and not be found, resulting in loss of user data or a computer deadlock. LDos attack since there has been extensive attention of researchers, the attack signature analysis and detection methods to prevent network security have become an important research topic. Some have been proposed for the current attacks were classified LDoS describe and model, and then in NS-2 platform for experimental verification, and then LDoS attack detection to prevent difficulties are discussed and summarized for the future such attacks detection method research work to provide a reference.

急倾斜特厚煤层冲击地压防治探索与总结

急倾斜特厚煤层开采顶板破断运动复杂,应力和能量演化规律特殊,在深部“三高一扰动”影响下,冲击地压防治不容乐观。基于某矿2016年冲击地压事故后急倾斜特厚煤层水平分段开采冲击地压防治经验,从急倾斜特厚煤层水平分段开采冲击地压发生机理、瓦斯突出与冲击地压综合防治和冲击地压管理详细介绍了该矿7年来急倾斜特厚煤层冲击地压防治经验。冲击地压发生机理方面,建立了顶板岩层倾斜悬臂梁模型,揭示了顶、底板覆岩结构破断失稳演化过程,划分了夹持煤体受力状态分区,提出了急倾斜特厚煤层冲击“夹持理论”。瓦斯突出与冲击地压综合防治方面,基于冲击地压灾害控制解危技术的强度弱化减冲理论,结合原有防突措施体系,提出了既能防冲且对防突有利的解危措施,形成了某矿瓦斯/CO_(2)突出-冲击地压“双防”技术体系,建立了适用于某矿急倾斜特厚煤层水平分段开采的冲击地压防治体系,以钻屑量和瓦斯吸解值验证了瓦斯突出防治的强度保障,同时以加强实施卸压措施工作面的微震事件分布及各能级总频次和能量对比,论证说明了卸压方案防治效果的有效性。冲击地压管理方面,形成了预测评价、监测预警、治理预防、效果检验、安全防护和教育培训“六位一体”综合防治架构,基于《煤矿安全规程》和《防治煤矿冲击地压细则》等各项规定,制定了Q/YJMD-—FC 0104-2022《窑街煤电集团有限公司煤矿冲击地压防治第四部分:冲击地压防治技术规范》。

现代化进程中的社会保障模式转型

在现代化过程中发展而来的现代社会保障制度,通过“社会权利范式”与“结构功能范式”的互动,与各国的现代化过程不断同频共振,并依据不同国家差异化的目标约束和条件约束,形成了危机救助、风险预防等社会保障模式。随着现代化的深化,作为现代化重要特征的社会保障模式,必将依现代化所带来的约束条件而做出适应性选择。由现代技术催生的社会经济形态、社会结构、新就业形态的变化和国民对社会保障权益诉求的不断提高,必然要求社会保障模式从危机救助、风险预防向权益保障模式的转型,以适应变化社会对国民社会保障的需求。在中国式现代化的目标约束与新经济、新技术发展,人口结构变化等条件约束下,基于风险共识、责任共担、权益共享的权益保障模式是中国社会保障达成社会权利范式与结构功能范式内在平衡的可行路径。

Preventive Control for Power System Transient Security Based on XGBoost and DCOPF with Consideration of Model Interpretability

This paper proposes a new approach for online power system transient security assessment(TSA)and preventive control based on XGBoost and DC optimal power flow(DCOPF).The novelty of this proposal is that it applies the XGBoost and data selection method based on the 1-norm distance in local feature importance evaluation which can provide a certain model interpretability.The method of SMOTE+ENN is adopted for data rebalancing.The contingency-oriented XGBoost model is trained with databases generated by time domain simulations to represent the transient security constraint in the DCOPF model,which has a relatively fast speed of calculation.The transient security constrained generation rescheduling is implemented with the differential evolution algorithm,which is utilized to optimize the rescheduled generation in the preventive control.Feasibility and effectiveness of the proposed approach are demonstrated on an IEEE 39-bus test system and a 500-bus operational model for South Carolina,USA.

算法推荐场域中的意识形态安全风险防控机制研究

随着数字智能技术的蓬勃发展,由算法推荐技术构建的算法推荐场域已成为人们获取信息的重要来源地,因此可通过根本立场方向、话语解释权力、信息呈现样态和信息筛选分发模式等路径深刻影响意识形态建设。当前,多样错误价值对主流意识形态的置换、技术中立对价值观念内核的隐藏、资本逻辑主导对人本逻辑回归的梗阻和特定信息投送对整体事实面貌的遮蔽共同呈现了算法推荐场域中意识形态安全的风险样态。针对此,必须协同构建主流价值引领机制、算法素养培育机制、算法技术管理机制和算法法律规制机制,有效防控算法推荐场域内的意识形态风险,维护意识形态安全。

交易安全视角下碳排放权交易风险防控

在“双碳”战略目标的引导下,碳排放权交易已成为国家气候治理的重要工具。2021年,全国碳排放权交易市场正式启动上线,生态环境部先后发布一系列有关碳排放权交易的管理办法和交易规则,但碳排放权交易活动中存在的和可能发生的交易风险并未全部纳入立法防控中。有关市场准入、交易标的、交易资金和回购交易引发的交易风险缺少必要的立法防控措施,应当从适度提高市场准入条件、加强交易标的真实性监管、实行交易资金来源审查和强化回购交易风险防控等方面完善碳排放权交易的安全环境,保障全国碳排放权交易市场健康发展。

社会风险预警与防控机制建设:一个社会燃烧理论的框架

社会风险治理面临治理观念困境、多元格局困境、社会参与困境。社会燃烧理论为解释社会治安风险的形成及防控提供了有效的逻辑支撑。依据社会燃烧理论,社会治安风险的形成需经历积累与萌芽、发展与升级、爆发与燃烧、平息与善后阶段。多重因素导致的社会矛盾是“可燃物”,失范的舆论是“助燃剂”,缺位的治理行为是“着火点”。完善社会风险治理,可从减少燃烧因子、控制助燃物质、降低社会温度三个层面着手,做好源头治理,建立常设性的预警机制,形成多元共治的协同治理局面。

敬畏与遵守社会规范行为的关系——有调节的中介模型

探讨公众遵守社会规范行为的影响因素是当下研究的重要主题之一.在疫情背景下,以遵守防疫行为准则为例,采用问卷法(被试805名)和实验法(被试105名),考察敬畏与公众遵守社会规范行为的关系,以及风险感知在其中的中介作用和心理控制源的调节作用.结果发现:特质敬畏与状态敬畏对公众的风险感知、遵守防疫行为准则均有正向预测作用;风险感知在特质敬畏和特定情景敬畏条件下与遵守防疫行为准则之间起部分中介作用,而在一般自然景观敬畏条件下,风险感知在其中起完全中介作用;敬畏与风险感知的关系受到心理控制源的调节,且在特质敬畏与状态敬畏条件下调节效果有所不同,但在外控倾向条件下,敬畏对风险感知的预测作用更强.研究结果有助于理解敬畏促进公众遵守社会规范行为的作用机制,对促进公众遵守社会规范行为的政策制定具有借鉴意义.
