Application Value of Multivariate Integration Teaching Method in Improving Nurses’ Knowledge Level of Continuous Nursing After Gastric Cancer Surgery and Its Impaction Patients’ Negative Emotions, Quality of Life and Adverse Reactions

To explore the application value of multivariate integration teaching method in improving nurses’ knowledge level of continuous nursing after gastric cancer surgery and its impact on patients’ negative emotions, quality of life and adverse reactions. 120 nurses were randomly divided into group A (n=60) and group B (n=60). After conducting the multivariate integration teaching to group A and the routine teaching to group B, each group was responsible for 60 gastric cancer patients admitted to our hospital from January 2019 to January 2020 to compare their knowledge level of continuous nursing after gastric cancer surgery and patients’ negative emotions, quality of life and adverse reaction rates (ARR). Compared with group B, trained nurses in group A had significantly higher knowledge level of continuous nursing after gastric cancer (P<0.001), and patients treated by nurses in group A had significantly lower negative emotion scores (P<0.001), higher quality of life scores (P<0.001) and lower ARR (P<0.05).Multivariate integration teaching method can effectively improve nurses’ knowledge level of continuous nursing after gastric cancer surgery, enhance their comprehensive nursing competence, and encourage them in providing continuous nursing with higher quality. Also, patients undergoing gastric cancer resection can, through communication with the trained nurses, enhance their self-nursing ability, alleviate negative emotions, and improve quality of life. Therefore, it should be promoted in clinical practice.

Scientific aspects of information exchange in electronic document management systems

The regularities showing the development of information exchange in the virtual space have been examined, electronic document management in the organization using information systems has been considered. It has been shown that the intellectualization of information systems is based on a powerful mathematical apparatus that provides work with texts by computer programs, based on the creation of models that include patterns necessary for the design of modern information search systems, as well as systems for automatic classification and analysis of texts.A document flow model based on a number of mathematical regularities, numerical methods of multivariate integration, the theory of mixed Queuing networks has been proposed. This model allows you to evaluate the multivariate integration of devices of electronic document management systems (EDMS), contributes to the formation of statistical data on document processing, provides with minimal time costs the formation of information flows in electronic document management systems, has a convenient user interface for object interaction programs. This model, based on the definition of a set of options for data transmission channels, a set of options for data collection equipment EDMS, a set of options for data processing equipment, a set of end devices of the EDMS communication environment, allows you to analyse the functionality of electronic document management systems.The proposed EDMS model shows that a number of functions of complex document management in an organization can be automated and optimized based on mathematical methods, which will reduce the time of document preparation, its routing and processing. Document management of the organization, using this EDMS, ensures optimization of information flows in the organization, contributes to the formation of important management decisions, taking into account all risk factors.

Tractability of Multivariate Integration Using Low-Discrepancy Sequences

We propose a notion of (t, e, s)-sequences in multiple bases, which unifies the Halton sequence and (t, s)-sequences under one roof, and obtain an upper bound of their discrepancy consisting only of the leading term. By using this upper bound, we improve the tractability results currently known for the Halton sequence, the Niederreiter sequence, the Sobol’ sequence, and the generalized Faure sequence, and also give tractability results for the Xing-Niederreiter sequence and the Hofer-Niederreiter sequence, for which no results have been known so far.
