Research on the Reform of Teaching Management Emergency Mechanism in University Based on Big Data

Sudden major public health events once again test the ability of the whole society to deal with emergencies.Universities are no exception.There are many kinds of management work in Colleges and universities,among which teaching management is the most important one,which is also one of the most affected in this epidemic situation.Therefore,in view of the problems of teaching management in Colleges and universities exposed in the epidemic,combined with the characteristics of independent colleges,starting from the aspects of teaching guarantee mechanism,teaching supervision mechanism,teaching process construction,teaching resources construction and so on,the advantages of big data technology,such as large amount of information,easy to communicate and easy to integrate,are fully used to put forward a set of open-minded,perfect mechanism and advanced technology teaching management emergency response mechanism.

Study on Emergency Management Mechanism of Public Health Emergencies

The outbreak of SARS in 2003 opened the way of public health emergency management in China.COVID-19 which suddenly outbroke in 2019 is still raging all over the world,and emergency management mechanism of China is being tested.Efforts to improve the emergency management mechanism can provide effective institutional guarantee for the overall victory of anti epidemic and the prevention and control of public health emergencies.

Earthquake Emergency Response System of High-speed Railway by Least Square Method

This paper studies the Least Square Method to define high-speed railway(HSR) earthquake risk and solve the problem of its emergency response mechanism. Based on the construction of a monitoring system for HSR earthquake emergency response, the technical operational procedures for HSR seismic emergency response are proposed. The quantity, scale, and location of HSR earthquake emergency response mechanism are defined, and the corresponding emergency response system is built. In particular, the earthquake emergency response system can conduct real-time continuous dynamic monitoring of seismic activity along the railway. When earthquake occurs, the intensity of the ground motion is detected by the system. When the earthquake monitoring value reaches the earthquake alarm threshold, it will send an alarm signal to the dispatch center, and the emergency power supply will be forced to cut off. The earthquake emergency response system will continue to monitor the follow-up ground motion acceleration. The system provides the operation scheduling center with a basis for train operation control to resume operation after stopping. The monitoring result of the system reduces the disaster, and the secondary disaster is caused by the earthquake. This paper improves the HSR response mechanism in detecting earthquake disasters. The result improves the ability of HSR to deal with earthquake disasters, and reduces casualties and economic and property loss caused by earthquake disasters.

Recommendations for Emergency Management of Rural Major Infectious Diseases in Non-epicenter Areas:Taking Village B during COVID-19 as an Example

This paper analyzed the key issues and challenges confronted in the governance of Village B in the non-epicenter area in rural areas of China during the COVID-19 pandemic.It clarified the weak points in the prevention and control of infectious diseases in Village B.A triple emergency management mechanism of"people-materials-environment"in rural areas should be established.It came up with constructive recommendations for scientifically and effectively responding to public health emergencies in rural non-epicenter areas,which is helpful to improve the rationality,legality and scientific effectiveness of the construction of emergency response mechanisms in rural areas.

Emergency access mechanism in IEEE 802.15.4 for wireless body area sensor networks

IEEE 802.15.4 protocol has attracted much attention in research and industrial communities as candidate technology for wireless body area sensor networks（WBASNs）.IEEE 802.15.4 supports the exclusive use of a wireless channel through guaranteed time slot（GTS）.However,on one hand,bandwidth underutilization rate may be lower because of the variance between the guaranteed bandwidth and the arrival rate.On the other hand,the waiting time for transmitting emergency notification is getting longer when the GTSs assigned to the nodes increase in WBASNs.To solve these problems,in this article,a new scheme is proposed to reduce transmission delay for the alarm notification in emergent situations.Simulation results are presented to validate the efficiency of the proposed scheme by comparing it with the medium access control（MAC） protocol of IEEE 802.15.4.

Risk warning technologies and emergency response mechanisms in Sichuan-Tibet Railway construction

Safety is one of the most critical themes in any large-scale railway construction project.Recognizing the importance of safety in railway engineering,practitioners and researchers have proposed various standards and procedures to ensure safety in construction activities.In this study,we first review four critical research areas of risk warning technologies and emergency response mechanisms in railway construction,namely,(i)risk identification methods of large-scale railway construction projects,(ii)risk management of large-scale railway construction,(iii)emergency response planning and management,and(iv)emergency response and rescue mechanisms.After reviewing the existing studies,we present four corresponding research areas and recommendations on the Sichuan-Tibet Railway construction.This study aims to inject new significant theoretical elements into the decision-making process and construction of this railway project in China.
