Their Master’s Thesis, from the Perspective of COVID-19, Contributing to Epidemic Prevention and Control

Updated：2022-06-07

Online communication, online counseling, and online defense..., affected by the COVID-19 epidemic, the graduation season of the school students this year has come to a perfect end online, which is destined to be special and unforgettable. COVID-19 outbreak on society, economy, life, etc., COVID-19 outbreak also exposed many problems to be solved. focusing on this, many graduates put the research perspective under the background of the epidemic, epidemic prevention and control measures on air quality, old community resilience assessment and promotion under regular epidemic, family resilience research, the epidemic as a dark horse on enterprise valuations, the police how to deal with the public health emergency, supplier evaluation selection system construction, emergency supplies distribution are their research topics. From the perspective of COVID-19, they put scientific research on the front line of epidemic prevention and control and write their papers on the front line of epidemic prevention and control. They have contributed their own strength to the epidemic prevention and control with what they have learned and thought, given full play to the function of scientific research in serving the society, and demonstrated the responsibility of the students in the new era.

“How to use the expertise of system science to effectively solve the social and public crisis faced by the public security organs in the context of major epidemics is the most meaningful research topic in my academic career.” Li Yandi, a graduate student, made an in-depth thinking and exploration in the graduation program. Under the influence of his supervisor, Professor Zhao Laijun, Li Yandi wrote the paper in the field of the police dealing with the major public health crisis in combination with the actual police work.

“The police practice in epidemic prevention and control has made me deeply understand the practical problems faced by the police in dealing with the public health emergency, making the design more targeted and operable, and improving the quality and efficiency of the police operation process.” But it is a huge challenge for Li to conduct theoretical research on tackling the public health emergency from a new perspective from the police. Under the guidance of his mentor Professor Zhao Laijun, he started from the epidemic-related police information text, carried out a three-level theoretical coding of 247,000 words of data text, summarized and refined the rooted theoretical model of the police operation process of the public security organs under the background of major epidemics, and put forward the reengineering design and optimization path of the police operation process.

“Professor Zhao Laijun, in the field of emergency management, has profound knowledge and rich practical experience, in the epidemic prevention and control stage to overcome difficulties through high frequency and efficient online meeting to my paper gave scientific and effective guidance, in the deep communication with teachers and constantly inspire new research ideas, improve the research technical route, formed the stand the double test of theory and practice.” Li Yandi recalled.

During the epidemic period, traffic was forced to suspend, and factories and enterprises were forced to stop work. Is the air quality significantly improved compared with the usual period, how much impact will the epidemic prevention and control measures have on the air quality, and can the change in air quality provide some inspiration and ideas for the future air pollution control? Under the guidance of his supervisor, Professor Zhao Laijun, Wang Yu, a graduate student, conducted relevant research as a starting point, and the relevant research results were published in the SCI journal Environment, Development and Sustainability.

In daily life, industrial production, transportation and living energy consumption are the three main factors affecting urban air quality. Epidemic prevention and control are most affected by industrial production and transportation. In the comparison and evaluation of the monitoring data before and after the COVID-19 outbreak in Shanghai, Wuhan and Tangshan, the prevention and control measures of COVID-19 reduced the air quality index and the concentration of all pollutants, and also found that the characteristics of different cities led to differences in the range of changes of pollutants. This is of certain guiding significance to the formulation of differentiated air pollution prevention measures in different cities. Said Wang Yu.

My graduation thesis topic selection is actually related to my internship experience, internship I participated in a biomedical project evaluation and investigation work, the biomedical industry outbreak, as a hot spot of primary market investment and the focus of secondary market positions, under the influence of the big variable, whether the original kinds of enterprise value evaluation model is still applicable to biological medicine enterprise is particularly important, is also a focus of research. Said Yu Mengdi, a graduate student.

Under the guidance of supervisor Xu, associate professor, he analyzed the COVID-19 as a black swan event multiple impact, comprehensive judgment of new outbreak after which kind of value assessment method applicability is better, and in the form of case analysis comparing the results of different valuation model, to verify the valuation of the two methods before and after the outbreak of the accuracy and applicability. In the process of paper writing, what I felt most was that the tutor gave him enough “freedom” to choose his favorite research direction, and there would not be many formalistic requirements. Under the guidance of the tutor again and again, I constantly inspired my ideas of paper writing.

Coincidentally, master's student Ding Xuxiang’s topic selection is also from internship experience, internship Ding Xuxiang students learn some investment strategy method, which is through observation between the market prices, options and bulk movements to judge the short-term future market pricing trend strategy, so want to continue to do in-depth research in this respect. As is known to all, the outbreak in recent three years is unprecedented, its impact from the fundamental will directly react to the capital market, causing many changes in strategies. After many times deep communication with supervisor Xu, associate professor, he determines under the background of the COVID-19, AH twin stock linkage based investment strategy research, through the comprehensive concrete display of performance of the COVID-19, intuitive analysis of the process and details of the impact. This not only enriches the research on the changes of various factors in the event of major public health events, but also provides investors with specific research closer to real investment strategies, and also gives more reference for the future direction of capital flow between Chinese markets.

Xi Jianwei, a master student, was selected from the various stories of many families during the outbreak of COVID-19 in late 2019. From then on, I gradually got ideas about my thesis topic. The persistent epidemic has tested the ability of families to resist risks, and families, as the most basic component of the society, have become the main body facing the COVID-19 epidemic. How to maintain family livelihood under the context of COVID-19 prevention and control to help families return to normal status has become an urgent problem to be solved. Said Xi Jianwei.

During the COVID-19, offline interview research is very difficult, so the subject mainly based on network questionnaire research way, questionnaire design level directly determines the paper level, in the process of questionnaire design, tutor professor Zhou Huijun meeting at least once a week, the point-to-point guidance, countless video conference, online discussion, repeated research grinding, tutor careful guidance let him have the opportunity to combine his public management, sociology, economics knowledge for epidemic prevention and control, mentor let him deeply feel the responsibility of a researcher and bear.

Emergencies represented by COVID-19 have had a huge impact on the global supply chain, and many enterprises are facing the risk of production delay or even interruption. This is the personal experience of Huang Weichao, who has been engaged in supply chain management in the machinery manufacturing industry for many years. Therefore, in the topic selection of the master's thesis, he fits the industry background and studies the selection of suppliers that consider the emergency factors. After analyzing the problems existing in supplier selection and the impact of emergencies on its supply chain, the supplier selection process, supplier classification, index system and selection method are improved, and a new supplier evaluation and selection system are constructed.

Talking about the writing process of the paper, Huang Weichao said: Combined with the industry background of the topic selection, I have improved my ability to use the theoretical basis to solve practical problems. From writing ability, data collection to analysis and sorting, from the thinking to problem solving methods, we have laid a more solid foundation for better work in the future. It is also hoped that the supplier evaluation index system established in the paper considering the influencing factors of emergencies can provide reference for the supplier selection of enterprises in the same industry. I am also particularly grateful to my tutor, Professor Zhao Laijun, who gave us many face-to-face lectures and online meeting guidance in the paper writing. Whether it was the topic selection, research method, research framework guidance, or the polishing of the paper format and text content, he gave the guidance in detail.”

As a public management student, usually contact courses related to social governance problems, the supervisor, Xie Yuan also often start from the current situation of urban governance to communicate with us, the old community as the weak link of urban community construction governance, especially under the COVID-19, the old community having more difficulties in dealing with internal and external risks, cannot effectively guarantee the quality of life of community residents. In the continuous communication and learning with my supervisor, I have been paying close attention to the relevant governance of the old urban communities. recalls Li Yanchen, a graduate student. Therefore, when choosing the topic of her master's thesis, she did not hesitate to study the resilience assessment and improvement of the old communities in Shanghai under the regular epidemic prevention and control.

Due to the current research for old community resilience assessment under regular epidemic prevention and control is relatively few, but also hope to build more scientific and practical evaluation framework , li Yanchen encountered a lot of problems during the process of combing the framework, in communication with Xie Yuan to analyse the encountered problems, Li gradually formed a clear idea, and completed the localization of the existing research framework.“Xie’s ‘all day long standby’, no matter what time to ask questions, she always replies patiently at the first time .” Li recalled, Although the unsteady epidemic has brought some difficulties to conduct field research, it is the unsteady epidemic that stimulate me setting the definite idea that it is important to strengthen the research on community resilience under the regular epidemic prevention and control. I hope my research results will help improve the epidemic prevention and control and improve the governance of communities and cities.”

Aerosol transmission is one of the main approach of COVID-19 transmission. During the epidemic prevention and control period, the virus may have potential transmission and exposure ways through the toilet-municipal sewage pipe network-sewage treatment plant-back to the natural water bodies. Therefore, it is particularly important to timely find out the risks existing in the drainage system, do a good job in problem prevention and control, and think about how to strengthen the emergency management of urban drainage facilities. Zhao Yin, a graduate student, engaged in urban sewage management for many years, after communication with his supervisor, professor Zhao Laijun, decided to do research on topic of urban drainage management under the large-scale epidemic outbreak, to analyze the current situation of urban drainage management and the existing main problems, hoping to put forward specific suggestions and countermeasures, to ensure the stable and healthy development of the city and people's life and property safety.

“As a graduate student, how to balance work and study is a challenge. During the Yangzhou epidemic, on the one hand, I worked overtime while served as a volunteer, on the other hand I took time to read literature, as well as did research, added self-pressure, scheduled self-time, to ensure the thesis complete smoothly; besides, my graduation coincided with the Shanghai epidemic, efficient offline communication, had to turn to online, my supervisor professor Zhao Lijun, acted as online instructor, gave online guidance, from research direction from a macro perspective to writing format details, I was encouraged.” Zhao Yin said.

After the outbreak of COVID-19, Zhao Jie joined the emergency rescue team of her supervisor Professor Ye Chunming's team. Zhao Jie as a graduate student majored in logistics engineering, at first has been focused on the domestic emergency resource allocation model, but as the domestic epidemic has been effectively controled, the Chinese government which maintains the epidemic in good situation also begins to help other countries for epidemic prevention and control, the fact makes her realize that the international society uniting and cooperating together, hand in hand, can is the only way to overcome the epidemic. With the suggestion of Teacher Ye, her research perspective was furtherly broadened and was committed to the construction of an emergency supplies distribution model which considered the psychological behavior of the people in the epidemic area under the international rescue.

The construction of the model was not done overnight, and Zhao Jie also had no clue in the solution algorithm innovation. Having heard of this, teacher Ye contacted several doctors to discuss and communicate with her. After many times of communication, the key nodes were opened, and the subsequent problems were solved. Zhao Jie said: “to participate in the background of the COVID-19 research, not only give me a deeper understanding of many conditions with no attention before, also have learnt a lot of knowledge related to epidemic prevention, so that I can give better service to people in need, which is more important, to make a modest contribution in solving the problem of material distribution in the epidemic.”
