BackgroundAs COVID-19 continues to spread globally, traditional emergency management measures are facing many practical limitations. The application of big data analysis technology provides an opportunity for local governments to conduct the COVID-19 epidemic emergency management more scientifically. The present study, based on emergency management lifecycle theory, includes a comprehensive analysis of the application framework of China’s SARS epidemic emergency management lacked the support of big data technology in 2003. In contrast, this study first proposes a more agile and efficient application framework, supported by big data technology, for the COVID-19 epidemic emergency management and then analyses the differences between the two frameworks.MethodsThis study takes Hainan Province, China as its case study by using a file content analysis and semistructured interviews to systematically comprehend the strategy and mechanism of Hainan’s application of big data technology in its COVID-19 epidemic emergency management.ResultsHainan Province adopted big data technology during the four stages, i.e., migration, preparedness, response, and recovery, of its COVID-19 epidemic emergency management. Hainan Province developed advanced big data management mechanisms and technologies for practical epidemic emergency management, thereby verifying the feasibility and value of the big data technology application framework we propose.ConclusionsThis study provides empirical evidence for certain aspects of the theory, mechanism, and technology for local governments in different countries and regions to apply, in a precise, agile, and evidence-based manner, big data technology in their formulations of comprehensive COVID-19 epidemic emergency management strategies.

Under the big data(BD) technology, colleges and universities pay more and more attention to educational technology, so as to follow up with modern information, digitization, and visualization. The courses of civil engineering teaching with traditional teaching methods and single knowledge of students are profit-only, applying data mining(DM) technology and BD technology to realize positive thinking mode.

This paper uses big data technologies to study base stations' behaviors and activities and their predictability in mobile cellular networks. With new technologies quickly appearing, current cellular networks have become more larger, more heterogeneous, and more complex. This provides network managements and designs with larger challenges. How to use network big data to capture cellular network behavior and activity patterns and perform accurate predictions is recently one of main problems. To the end, firstly we exploit big data platform and technologies to analyze cellular network big data, i.e. Call Detail Records (CDRs). Our CDRs data set, which includes more than 1000 cellular towers, more than million lines of CDRs, and several million users and sustains for more than 100 days, is collected from a national cellular network. Secondly, we propose our methodology to analyze these big data. The data pre-handling and cleaning approach is proposed to obtain the valuable big data sets for our further studies. The feature extraction and call predictability methods are presented to capture base stations' behaviors and dissect their predictability. Thirdly, based on our method, we perform the detailed activity pattern analysis, including call distributions, cross correlation features, call behavior patterns, and daily activities. The detailed analysis approaches are also proposed to dig out base stations' activities. A series of findings are found and observed in the analysis process. Finally, a study case is proposed to validate the predictability of base stations' behaviors and activities. Our studies demonstrates that big data technologies can indeed be utilized to effectively capture network behaviors and predict network activities so that they can help perform highly effective network managements.

The issue of studying a person's abilities to perceive a large amount of information during the period of distance learning is poorly understood and extremely relevant. The problem of our research is the identification of modern technologies for supporting education system specialists in working with a large amount of information, the ability to perceive and analyze it, as well as reducing the level of information fatigue among educational workers during distance learning, since the digitalization of education has an intense negative impact on mental processes of employees, on their psychological and social well-being. The article describes the results of a theoretical study of the interdisciplinary convergence of the indicated problem, expanding the understanding of Big Data technology through the psychology of abilities and the psychology of education. At the same time, the authors of the article note the increasing role of Big Data technology in the modern conditions of a pandemic and distance learning. Big Data technology or «Big Data» means a certain system of methods and some algorithms for working with large amounts of data. These data sets are aimed at acquiring a qualitatively new understanding of what this information carries. Now there are four main directions of the formation of large volumes of data in the education system. These are online training systems, internal information systems of educational organizations, information about employees and the requirements of the organization's management to potential employees, information about students. Having studied the main directions of Big Data development when processing large amounts of various information, we found links with the implementation of Big Data methods, tools and technologies in the field of education and the efficiency of employees. The authors identified and studied an important function of Big Data in the period of distance learning – it is the creation of psychological well-being of employees of the education system and the leveling of the problem of information fatigue.
