Challenges of COVID-19 prevention and control: A narrative review

This narrative review aims to highlight some of the factors contributing to challenges faced by many countries in controlling the spread of COVID-19 pandemic that continues to rage around the world,especially after stoppage of official prevention and control activities.A literature search was conducted on PubMed,and Google using search terms“COVID-19”,“challenges”,“prevention”,and“control”in different combinations.COVID-19 prevention and control challenges are related to health-system,vaccines,administration,and society culture.Controlling the spread of COVID-19 necessitates cooperation between community leaders,healthcare professionals,religious leaders,and the public.

Closed-loop prevention and control research of coal mine safety management

According to the current problems of safety management processes in coalmine enterprises,we introduced barrel theory to coal mine safety management,constructedthe closed-loop structure of a coal mine safety management system,andpointed out that efficient safety management lies in three factors:safety quality of all ofthe staff in coal mine enterprises,weak links in security management systems,and cooperationamong departments.After conducting detailed analysis of these three factors,we proposed concrete ways of preventing and controlling potential safety hazards duringthe process of coal mine production.

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.

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.

Detecting Man-in-the-Middle Attack in Fog Computing for Social Media

Fog computing(FC)is a networking paradigm where wireless devices known as fog nodes are placed at the edge of the network(close to the Internet of Things(IoT)devices).Fog nodes provide services in lieu of the cloud.Thus,improving the performance of the network and making it attractive to social media-based systems.Security issues are one of the most challenges encountered in FC.In this paper,we propose an anomalybased Intrusion Detection and Prevention System(IDPS)against Man-in-theMiddle(MITM)attack in the fog layer.The system uses special nodes known as Intrusion Detection System(IDS)nodes to detect intrusion in the network.They periodically monitor the behavior of the fog nodes in the network.Any deviation from normal network activity is categorized as malicious,and the suspected node is isolated.ExponentiallyWeighted Moving Average(EWMA)is added to the system to smooth out the noise that is typically found in social media communications.Our results(with 95%confidence)show that the accuracy of the proposed system increases from 80%to 95%after EWMA is added.Also,with EWMA,the proposed system can detect the intrusion from 0.25–0.5 s seconds faster than that without EWMA.However,it affects the latency of services provided by the fog nodes by at least 0.75–1.3 s.Finally,EWMA has not increased the energy overhead of the system,due to its lightweight.

社会治理视域下学校食品安全监管策略研究

学校食品安全问题关乎广大师生切身利益,是社会大众关注的焦点。遵循“结构-运行-保障”的制度逻辑,构建“监管主体-监管方式-监管评价”分析框架,剖析当前学校食品安全监管存在的问题及原因,包括监管主体政策执行疏漏,应对突发事件能力不足;监管体系有待完善,学校食品外包模式有待改进;监管评价的绩效评估体系不完善,监管人的食品安全意识不足等。总结域外相关监管经验,包括完善的法规体系、多层次监管模式、严格的行业准入、严厉的惩罚处罚以及注重校园食品安全教育和家长积极参与的制度等。在此基础上,提出严格落实学校“一把手”责任制,持续完善学校食品安全制度机制,不断健全学校食品安全监督体系,重点加强学校食堂食品外包管理,建设食品安全智慧综合系统平台,健全食品安全突发事件应对机制,加强学校餐饮行业人员安全培训等建议,为改善学校食品安全状况治理提供有效策略。

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。

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。

司法鉴定机构数据安全的规范进路

司法鉴定机构数据利用规制是司法鉴定数据安全的基础。“四大类”司法鉴定均存在数据安全风险,司法鉴定机构数据安全风险识别应坚持类型化思路展开,已有的《网络安全法》《民法典》《数据安全法》《个人信息保护法》为司法鉴定机构数据安全提供了制度指引和基本要求。司法鉴定机构数据安全规制应完善相应法律制度,建立涉案数据安全监管机制,培育数据安全意识,提升数据合法利用能力。

本质安全视域下健全平安建设长效机制的思考——以H省为研究样本

本质安全作为一种高层次的安全管理理念,强调从源头防范化解系统性风险和预防事故的发生。H省自2021年9月践行本质安全理念以来,持续致力于健全平安建设长效机制,坚持控增量、减存量、防变量的原则,在“预”字上下足功夫,在“防”字上做好文章,全力以赴打击犯罪,积极化解积案和矛盾纠纷,开展了一系列有益探索。结合多地实践来看,平安建设的长效机制构建还存在一些问题。对此,基于本质安全视角客观审视这些问题,建议从强化社会治理共同体、创新公共安全体制机制、完善社会治安防控体系、筑牢舆情风险立体化防控体系、健全应急管理体系等方面着手促进长效机制建设,为平安建设更高水平、可持续发展打造坚实的支撑。

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。
