At the turn of 2019-2020, a new epidemic broke out in China. China has entered the critical stage of epidemic prevention and control. And The severe situation has led to the failure of normal opening of new semester in Chinese colleges and universities. In order to effectively guarantee the education, teaching and talent cultivation in colleges and universities, the Ministry of education of China has rapidly put forward the requirements of launching online teaching. Therefore, under the situation of Novel Coronavirus Pneumonia (Hereinafter referred to as 2019-nCoV) prevention and control, online teaching in Chinese colleges and universities is widely used and develops rapidly. However, the demand for online education has been released in a short time and on a large scale, and each online teaching platform has encountered unprecedented pressure and challenges. In this regard, based on the situation of 2019-nCoV prevention and control in China, this paper demonstrates how the Chinese government deploy online teaching in an all-round way with specific measures, how the Chinese colleges and universities implement massive online teaching quickly, how teachers and students adapt to online teaching quickly. At the same time, this paper carries out empirical analysis to show the process and effectiveness of online teaching in Chinese colleges and universities in the unprecedented state of 2019-nCoV prevention and control with specific examples. On this basis, it analyzes and summarizes the advantages and disadvantages, so as to facilitate the later improvement and provide reference.

The reform of Ideological and political courses in Colleges and universities is fast and steady, but a new outbreak has brought impact and challenge to the current teaching mode of Ideological and political courses. Under the call of "No classes without stopping teaching, No classes without stopping learning", colleges and universities rely on the existing information technology means to build online teaching platform, and ideological and political teachers actively carry out online teaching by using all kinds of modern technology. Under the guidance of national policies, school logistics support and the implementation of Ideological and political teachers, the teaching order of Ideological and political courses during the epidemic prevention and control period was ensured. Although there will inevitably be some problems in the teaching process, combined with the nature of the ideological and political textbooks and the progress and quality of online teaching during the epidemic prevention and control period, this paper reflects on the problems in the online education of Ideological and political courses, puts forward the corresponding solutions, and stands that the online education of Ideological and political courses in Colleges and universities can completely turn passive into active. Therefore, it is feasible to change the online teaching of Ideological and political course from "forced" to normalization.

In a large-scale epidemic, such as the novel coronavirus pneumonia (COVID-19), there is huge demand for a variety of medical supplies, such as medical masks, ventilators, and sickbeds. Resources from civilian medical services are often not sufficient for fully satisfying all of these demands. Resources from military medical services, which are normally reserved for military use, can be an effective supplement to these demands. In this paper, we formulate a problem of integrated civilian-military scheduling of medical supplies for epidemic prevention and control, the aim of which is to simultaneously maximize the overall satisfaction rate of the medical supplies and minimize the total scheduling cost, while keeping a minimum ratio of medical supplies reservation for military use. We propose a multi-objective water wave optimization (WWO) algorithm in order to efficiently solve this problem. Computational results on a set of problem instances constructed based on real COVID-19 data demonstrate the effectiveness of the proposed method.

In year 2020, a large-scale outbreak of pneumonia caused by new coronavirus has affected the development of many industries and enterprises in China. Under the strong leadership of the Chinese government, the development of the epidemic situation in China has been well controlled. The development of various industries also began to show a good situation, many large-scale sports competitions also need to be restored. In order to ensure the normal development of large-scale sports events, we need to consider the development of epidemic situation to determine the time of sports events. Based on the study of FPGA theory, this paper designs a specific scheme of programming and system debugging, which includes a variety of program operations. In order to better predict the situation of the epidemic situation, this paper also uses the basic knowledge of machine learning to establish a relevant model to evaluate the situation of large-scale sports events under the development of the epidemic situation, and provide feasible suggestions for the recovery of large-scale sports events under the epidemic situation.

Recently, an unprecedented coronavirus pandemic has emerged and has spread around the world. The novel coronavirus termed COVID-19 by the World Health Organization has posed a huge threat to human safety and social development. This mini review aimed to summarize the online education mode and plans for schools to resume full-time campus study in China during COVID-19. Chinese schools have made significant contributions to the prevention and control of the transmission of COVID-19 by adopting online learning from home. However, normal opening and classroom teaching have been affected. For education systems at all levels, online education may be an effective way to make up for the lack of classroom teaching during the epidemic. To protect staff and students from COVID-19, the timing of students returning to full-time campus study needs to be considered carefully. Reviewing and summarizing of the Chinese education system's response to the virus would be of great value not only in developing educational policy but also in guiding other countries to formulate educational countermeasures.

Abstract From December 31, 2019, a large-scale 2019 novel coronavirus disease (COVID-19) broke out in China. Tracking and analyzing the heterogeneity and effectiveness of cities’ prevention and control for COVID-19 epidemic is essential to design and adjust epidemic prevention and control. The number of newly infected cases in 25 China’s worst cities for COVID-19 epidemic from January 11 to February 10 was collected. The heterogeneity and effectiveness of these 25 cities’ prevention and control measures for COVID-19 were analyzed by using a estimate time-varying reproduction numbers method and a serial correlation method. The results shown that the effective reproduction number (R) in 25 cities showed a downward trend as a whole, but there was a significant difference in the R change trends among cities indicating that there was heterogeneity in the spread and control of COVID-19 in cities. Moreover, the COVID-19 control in 21 of 25 cities were effective and the risk of infection was decreasing due to their R had dropped below 1 on February 10, 2020 and the average decline of R in the past 5 days was greater than 0, while cities of Wuhan, Tianmen, Ezhou and Enshi were still difficult to effectively control the COVID-19 epidemic in a short period of time because their R was also greater than 1.

The delay of the school term in China, caused by the Corona Virus Disease 2019（COVID-19）pandemic, reinforced the importance of remote teaching. The latter enabled teaching operations to continue nationwide and provided colleges and universities with opportunities to carry out education and teaching reforms that are also aligned with the rapid development of technology. Upon considering remote teaching operations in China University of Geosciences, Beijing, this paper puts forward recommendations for teaching and education management practices. We propose that colleges and universities break free from the restraints of traditional teaching methods, establish a security system of online courses, offer high quality online contents, and accelerate the construction and sharing of effective courses.

Against the backdrop of the COVID-19 outbreak, an emergency policy initiative called “Suspending Classes Without Stopping Learning” was launched by the Chinese government to continue teaching activities as schools across the country were closed to contain the virus. However, there is ambiguity and disagreement about what to teach, how to teach, the workload of teachers and students, the teaching environment, and the implications for education equity. Possible difficulties that the policy faces include: the weakness of the online teaching infrastructure, the inexperience of teachers (including unequal learning outcomes caused by teachers’ varied experience), the information gap, the complex environment at home, and so forth. To tackle the problems, we suggest that the government needs to further promote the construction of the educational information superhighway, consider equipping teachers and students with standardized home-based teaching/learning equipment, conduct online teacher training, include the development of massive online education in the national strategic plan, and support academic research into online education, especially education to help students with online learning difficulties.

Abstract Background As the COVID-19 outbreak influenced teaching in China, Chinese medical colleges and universities carried out massive online education with the participants of more than one million students on the for-profit or non-profit big–data teaching platforms, based on existing online teaching resources and other ways such as MOOC, Micro-course, Live-course and interactive discussion. Methods A questionnaire survey was conducted via two rounds of 56-in-total questions on overall situations, platforms, teaching methods, training, teachers and students’ experiences, and encountered problems for 1747 teachers and 7223 students, which involved 741 courses. Comparative analysis was done on the survey results. Results A majority of teachers and students were satisfied with teaching platforms and effects; large commercial teaching platforms could provide better services; 67.21% of teachers and 64.67% of students preferred live teaching; only 76.84% of teachers and 58.69% of students were systematically trained; weak network, lack of training, overcrowded access to teaching platforms, lack of interaction, lack of efficient real-time evaluation and fatigue were current difficulties. Conclusions Good results of massive distance online education and teachers and students’ satisfaction with teaching platform performance show that online education can be used as a main means to replace traditional classroom education in emergency situations.
