Abstract ( 7 )
The comprehensive risk assessment of COVID-19 is a key approach to the comprehensive epidemic risk management while the assessment method is the key to the epidemic risk assessment. This paper uses the public security "triangular model" and considers the three factors, i.e., the incident(the hazard of the virus itself), the vulnerability of hazard-affected carriers(the vulnerability of vulnerable groups), and the effectiveness of emergency management to establish a multidimensional risk assessment method, which can help to provide effective method for the next epidemic response and plans of resource allocation. According to the assessment results, the top five provinces with highest comprehensive risk are respectively Hubei, Shanghai, Hong Kong, Beijing and Guangdong. Within Hubei province, the top four cities are Wuhan, E'zhou, Xiaogan and Huanggang.

Abstract ( 5 )
The medical and health facilities are important infrastructure for improving people's livelihood and protecting people's health. The relationship between supply and demand of medical and health facilities in China needs to be reexamined in the epidemic situation of the COVID-19. Based on the statistics of the medical and health facilities in 2018, this paper selects the number of medical and health facilities per capita, the number of beds per medical and health facilities per capita, and the number of medical and health personnel per capita to make a comparison. This paper analyzes the regional distribution of medical and health facilities, the difference between urban and rural areas, and the difference between public and private medical and health facilities in China, and compares them with other countries. In view of the realistic problems of hospitals fighting against COVID-19 in Wuhan, the following suggestions are made:strengthening the medical and health facilities of provinces in South China, increasing the investment in primary health care facilities and medical stuff, guiding private medical institutions to participate in the management of public health emergencies, and reserving emergency sites for public health emergencies in hospital planning.

Abstract ( 175 )
In the major epidemic prevention & control work on the novel coronavirus pneumonia (COVID-19), the intelligent unmanned systems play a great role. In the epidemic monitoring stage, we have the unmanned aircraft systems (UAS) for high altitude monitoring, the robots for epidemic prevention publicity and for elimination of virus by dispersing drugs, and the intelligent infrared system for measuring the temperature, which work effectively, providing a powerful technical means for epidemic prevention & control. In the stage of prevention and treatment, the 5G remote consultation platform, the diagnosis and treatment robots, and the movable negative pressure isolation cabin effectively work for the problems of infection risk caused by the direct contact treatment and for the safety of the front-line medical staff. In terms of the material support, the intelligent production system and the UAS play a key role in the medical and life necessity production and deployment, to greatly improve the efficiency of the supply part.

Abstract ( 5 )
By 18:00 on February 16, 2020, the cumulative number of confirmed cases caused by COVID-19 epidemic in China has reached 68,592. The epidemic control work is at a critical period. However, the proliferation of the pseudo-science Internet rumors during the COVID-19 epidemic cause widespread adverse social events, such as the blind rush purchases and hoarding, which seriously affect the epidemic control and the normal social order. Taking the COVID-19 epidemic as an example, this paper reviews the definitions of the pseudo-science and Internet rumors proposed by domestic and foreign scholars. Four major pseudo-science Internet rumors that have had a greater impact in this epidemic, and the data on Sina Weibo(microblog) are used as examples to analyze the spread characteristics of the pseudo-science Internet rumors. Based on the SEIR model, this paper comprehensively analyzes factors such as the lag of official intervention, the bandwagon effect of individual information acceptance, and the spread characteristics of rumors, and the mechanism of the pseudo-science Internet rumors in major public health emergencies through numerical experiments. Finally, this paper proposes countermeasures for the pseudo-science Internet rumors in major public healthy emergencies from various angles.

Abstract ( 7 )
In early 2020, the COVID-19 spread to all parts of China and even other countries in a short period of time. The severe epidemic situation would put a psychological pressure on the public, resulting in anxiety, panic and other emotions, even some irrational behavior such as scare buying and becoming credulous of rumors. The risk preference is defined as the degree of the risk that people are willing to accept in their decisions and behaviors. In this public health emergency, the consumers' purchase and use of sanitary and epidemic prevention products reflects their risk preference. This paper explores the relationship between the public risk preference and the purchase behavior through a questionnaire survey, and it is found that the factors influencing the purchase behavior mainly include the gender factors, the perceived risk level and the severity of the epidemic situation in the residence area, as indicated by the Association Rule Mining.
