Researching the possibilities of using digital financial instruments by future economists for sustainable development purposes

Introduction. The authors explore the problem of developing digital financial literacy as the most important characteristic feature of positive financial behavior in the context of the transition to the digital economy. The purpose of this article is to identify priorities and trends in using digital financial instruments by future economists for sustainable development purposes. Materials and Methods. The methodological basis of the study is the strategy of sustainable development, the ideological foundations of which determine the need for readiness to live and act in changing conditions, to plan socio-economic development taking into account the limitations of activities and the consequences of decisions made. The main method of the empirical part of the study is T. Saaty’s scale which was employed in order to identify global priorities in the use of digital financial instruments. A sociological survey was conducted among students of the Financial University under the Government of the Russian Federation, Omsk State University named after F.M. Dostoevsky, Omsk State Technical University, schoolchildren of specialized economics classes (Gymnasia 19, Omsk) to identify priorities and trends in the use of digital financial instruments by future economists, taking into account gender and age preferences. Results. The ideas about the level of awareness about the problem of developing digital financial literacy are systematized, explaining the relationship between digital and financial literacy from the point of view of the prospects of the socio-economic space. Global priorities of the use of digital financial instruments by respondents were identified: the general sample prefers to work with optimal combinations of 2 banking payment systems. Analysis of correlations by gender shows that male respondents are better than the sample at the range limits, and female respondents are in the middle. The interpretation of the answers characterizes the women’s choice as stable, middle options of behavior (2-3 cards), which are less risky. Men, on the contrary, consider risk as a challenge that encourages activity, and go to the border of the sample (1-4 cards). A similar trend is typical for the age groups between 17 and 20 years. This, on the one hand, is explained by the psychological peculiarities of gender, and on the other hand, by active advertising campaigns of digital sets of financial services offered by leading Russian banks. An assessment of students’ awareness of new models of the digital economy has been obtained, demonstrating a good correlation as respondents grow older, which determines the positive dynamics of digital financial literacy of future economists (1-4 year undergraduate students) in the light of current labor market trends. Conclusions. The results of the research confirm that active use of digital financial instruments determines affirmative dynamics of positive financial behavior of future economists for the purpose of sustainable socio-economic development.

Educational data mining in a university using LMS Moodle

Educational data mining is a technology for processing big data collected through educational portals and used for assessing the quality of educational content and predicting educational outcomes. Various data analysis methods are applied in the implementation of this technology, including anomaly detection, association rule mining, classification, cluster analysis, regression analysis, and factor analysis. Each of these methods uses special tools, such as spreadsheets, high­level programming languages (Python or R), low­code platforms (Loginom, Orange), or specialized analytics modules integrated into educational portals. The article reveals the features of the “Analytics” module embedded in LMS Moodle for tracking and optimizing the educational process. The authors provide recommendations for configuring and using this module in the educational process. The module “Analytics” allows to create forecasts of the success rate of mastering a separate training course without programming skills , does not require data preprocessing for analysis, and allows to quickly take measures to improve the educational process based on the results of the forecast. However, the module has a number of disadvantages (limited attributes and forecasting models, high requirements for computing power to run model training and build forecasts), so often administrators of educational portals disable this module. In this regard, an experiment was conducted to train a classification model for predicting students’ examination scores based on students’ activities on the educational portal of Nosov Magnitogorsk State Technical University. In the course of the experiment, data on students’ activity on the university’s educational portal for one academic year were taken, and machine learning models were built to predict examination scores for an individual student and subject. The results of the experiment showed F1 74 % in predicting the score that the students would receive on the intermediate assessment. This confirms the effectiveness of using educational data mining based on user data from educational platforms.

Применение конопляного урбеча и нутовой муки в составе комбинированных творожных десертов

Purpose. Determination of the functional and technological compatibility of whipped food systems of combined curd desserts with neoprotein ingredients. Materials and Мethods. Experimental research and development of samples were carried out in the conditions of the Department of Food Production Technologies of Volgograd State Technical University and Complex Analytical Laboratory of VRIMMP (Volgograd). The object of the study was combined curd desserts with neoprotein ingredients: urbech from peeled hemp seeds in the curd part and chickpea flour in the biscuit part. All studies within the framework of this work were carried out in accordance with regulatory documents of state standards of the Russian Federation: assessment of organoleptic indicators – according to GOST R ISO 22935-2-2011 and GOST 31986-2012; whipped of the curd part was determined according to GOST R 52175-2003, mass fraction of moisture – according to GOST 3626-73, titratable acidity – titrimetrically (GOST 3624-92), mass fraction of moisture in the biscuit – according to GOST 5900-2014. Results. Sample of curd part No. 2 with the addition of 6% urbech from purified hemp kernels and sample of biscuit No. 2 using chickpea flour after frying demonstrated the best organoleptic characteristics. The results of physicochemical and rheological tests showed that the addition of urbech increases whipped of the curd part by 2 times, reduces acidity by 11.1% and increases mass fraction of moisture by 5.5%, and frying chickpea flour helps to increase the mass fraction of moisture in the biscuit, which slows down staling. The use of neoprotein components enriches the combined whipped curd product with plant protein, dietary fiber, macro- and microelements. Conclusion. Production of combined whipped curd products using neoprotein components - hemp urbech and fried chickpea flour, is advisable due to the improvement of the organoleptic, physico-chemical and rheological properties of both the curd and biscuit parts of the product, as well as increasing their nutritional and biological value.

Автоматизированное технологическое обеспечение и повышение эксплуатационных свойств деталей машин

The article outlines two directions of automated engineering support for the operational properties of machine parts (wear resistance, contact stiffness, etc.). The first direction is a traditional one. It's a two-stage provision of the operational properties of machine parts: in the first stage it is the dimensioning of working surfaces quality of the part that determines the required values of operational properties; in the second stage it is technological provision of quality parameters for the working surfaces of machine parts. The second new direction is a single – stage automated engineering support for the current operational properties of machine parts, which has been actively developed over the past 25 years at the Bryansk State Technical University. It is based on the theoretical and experimental dependences of the relationship between the operational properties of machine parts directly with the processing modes of their working surfaces. Various automated systems of scientific research have been developed to obtain experimental dependencies. An example of such an automated system for studying contact stiffness is given. Adaptive control systems used on various machines for high-performance engineering support aimed at obtaining the required quality parameters of the treated surfaces and their operational properties have been developed. When processing new materials and taking into account the absence of theoretical and experimental data, it is possible to use self-learning technological systems. An example of such a system used for a lathe, is given. All these developments contribute to the creation of the machines with artificial intelligence.

Methodological aspects of professionally-oriented mathematics education for students of technical university

This paper examines the problems of teaching mathematics at a technical university in the context of new educational standards.

The study of this discipline is aimed at the formation of both general professional and professional, as well as universal competencies. At the same time, a comparison of two generations of standards (current and previous) of higher education in the chosen field of study made it possible to establish the transfer of a significant number of classroom hours to independent work of students. The established fact necessitates the introduction of modern methods, forms and conditions of the organization into the learning process. The study was conducted on the basis of Samara State Technical University. The aim of the study is to determine the pedagogical conditions for the organization of the educational process, which make it possible to more effectively prepare students of a technical university for future professional activity. The pedagogical conditions were developed taking into account the orientation of the learning process towards digitalization, the introduction of information technologies, the development of financial literacy of students, as well as the activation of their independent activities and cognitive interest. The article presents the implementation of these conditions in the educational process of Samara State Technical University.

МОРФОЛОГИЧЕСКИЕ И ФУНКЦИОНАЛЬНЫЕ ПОКАЗАТЕЛИ СПЕРМАТОЗОИДОВ БЫКОВ ПРИ КРИОКОНСЕРВАЦИИ

The purpose of the study is to analyze the influence of the freezing and thawing cycle on the morphofunctional parameters of bull sperm. The study was conducted at Nizhegorodskoe LLC on breeding work in the Kstov municipal District of the Nizhny Novgorod Region, on the basis of the Department of Physiology and Anatomy of the Institute of Biology and Biomedicine of the Nizhny Novgorod State University named after N.I. Lobachevsky and the Department of Physiology, Animal Biochemistry and Obstetrics of Nizhny Novgorod State Technical University. The object of the study is the sperm production of black-and-white bulls. Semen was diluted with sterile BioXcell medium. Native diluted sperm and sperm after deep freezing were studied. Motility and the average speed of sperm movement were analyzed on a sperm analyzer SA-500 from Biola (Russia). To assess the ultrastructure of spermatozoa, a Hitachi SU8220 electron microscope (Japan) was used. Using a laser interference microscope MIM-340 (Russia, Yekaterinburg), the morphology of spermatozoa was studied in real time without fixation or staining. After cryopreservation of the sperm, there was a decrease in the biological usefulness of sperm, which is confirmed by a decrease in motility by 13.77% (p ≤ 0.05) and the average speed of sperm movement by 12.95% (p ≤ 0.05). Using electron and laser interference microscopy, it was shown that the chromatin of thawed spermatozoa was insufficiently condensed and contained fibrils. After cryopreservation, the position of the acrosome was changed in 6.23% (p ≤ 0.05) of sperm, and the shape of the acrosome was changed in 18.64% (p ≤ 0.05) of cells. After freezing and thawing, 7.01% of sperm showed a decrease in head length, 17.90% - a decrease in body length, and 9.53% - a decrease in sperm tail length. The use of modern methods for assessing sperm viability is of great importance for understanding the processes occurring during sperm cryopreservation and allows us to develop ways to improve the quality of sperm du¬ring freezing and thawing.

Studies on in-flight aircraft rerouting

With the publication of this article, the authors continue the research on the development and testing of a methodology for in-flight aircraft rerouting which have begun in previously published articles in the Civil Aviation High Technologies of the Moscow State Technical University of Civil Aviation. This article presents the results of the study in terms of developing the potentials of the methodology from reconfiguring a route of a hypothetical aircraft and obstacles in the horizontal plane, which were previously demonstrated, prior to rerouting in both the horizontal and vertical planes for two different types of obstacles: 1) ground natural or artificial (mountain, power line support, etc.); 2) air (squall line, prohibited flight area, etc.) and their combinations using an example of a Mi-8 helicopter flight on route using a real digital map of the terrain. As mentioned above, a large amount of aviation accidents is associated with the loss of control in-flight, as well as the collision with terrain in a controlled flight (categories LOC-I, CFIT, LALT). As a result of the investigation of the aviation accidents, it was found that these accidents are often caused by the requirement to reroute quickly due to obstacles, for example, a squall line. When determining alternatives to avoid an obstacle, as well as while implementing the selected route for avoiding action, the crew makes errors due to the increased psychophysiological load and lack of time. The methodology and the algorithms, proposed by the authors, make it possible to assess the safety of an original route, estimate options for alternatives to avoid around obstacles detected in-flight, check them for feasibility, taking into account aircraft performance, flight envelope, and also select the optimal route from the view of some criterion, for example, based on minimizing the route length increase, reducing additional fuel consumption, the time required to implement a new route of flight, etc.

Аdaptation of foreign students in the framework of the implementation of the third mission of the university

Introduction. The research topic is conditioned by the need to develop innovative adaptation measures for international university students, which are an important channel for transferring information about the country to the world community. Decoding the national values of the recipient country corresponds to the intention of the third mission of the university, understood as its contribution to the development of the regional, national and global community. The purpose of the study is to analyze the satisfaction of foreign students with the conditions of the new educational environment of the university and to develop a comprehensive program for their adaptation. Materials and methods. The study was conducted in Novosibirsk State Technical University using the survey method by filling out a questionnaire by respondents and a formalized interview. Closed alternative questions were used in the questionnaire. International students from near and far abroad participated in the survey. The data was processed and visualized using the method of bar and pie charts. The results of the study. The data of the conducted survey of foreign students allow us to conclude about the generally successful adaptation environment of the university. However, some indicators have revealed the need to improve the adaptation process, mainly in its socio-cultural aspect. The answers to the question "How easily did you join the educational process of NSTU?" revealed the fact that about 52% of foreign students felt discomfort after arriving to study in Russia, especially this should be attributed to citizens of non-CIS countries. When answering the question "Have you encountered difficulties in establishing contacts with Russian students and the local population due to differences in values, traditions and customs?" 44% of respondents acknowledged the existence of problems. Thirty-nine percent of respondents considered the main barrier to effective communication to be a lack of understanding of the motives of Russians' actions. New formats of adaptation measures are required that decode the system of cultural values of the recipient country for foreign students and involve them in the scientific, cultural and economic life of the region. Thirty-two percent of respondents spoke about their lack. Conclusions. The factors of successful adaptation of students at the university are identified, new formats of socio-cultural activities are proposed that can demonstrate national norms and traditions, such as an adaptive VR course, virtual travel, sightseeing routes around the city and the university area, adaptation quests. Types of adaptation activities are included in a comprehensive program designed to convey both the values of the university, its location region, and the values of the recipient country.

Alignment Error Estimation of the Conductive Pattern of 3D-Printed Circuit Boards

Introduction. When manufacturing printed circuit boards (PCBs), including their prototypes, the proper alignment of PCB layers is mandatory. While the causes and preventive measures against misalignment in PCBs manufactured using conventional technologies are known, research into alignment errors in 3D-printed PCBs is still ongoing. Another task regarding 3D printing, which is related to topological accuracy (alignment errors in particular), consists in ensuring the opportunity to remove the printed part of the product in order to perform operations thereon, such as embedding components, followed by its return and continuation of the printing process.Aim. Numerical estimation and analysis of the causes of layer-to-layer alignment errors in PCBs manufactured using 3D printing.Materials and methods. The research was conducted using the following materials and equipment: Polyethyleentereftalaatglycol (PETG); an Ultimaker Cura slicer; an Ender 3 S13D printer; a brass nozzle with a diameter of 0.3 mm. The study was conducted using the facilities of the Additive Technologies Center, Bauman Moscow State Technical University. Interlayer alignment errors are estimated by microsection analysis and X-ray inspection, as well as using the misalignment decomposition method described by Yu.B. Tsvetkov for electronics.Results. The possibility of manufacturing PCB prototypes with three conductive layers is demonstrated, including a method for removing the printed part of the product and its further return in the printing process using printed pins. Large-scale distortions were found to make the largest contribution to the alignment error: on average, approximately 150 gm for each layer when compared to its 3D model and approximately 60 gm when comparing the topology of the top layer with the bottom layer. These values exceed the common misalignment value of 50 gm for the pin lamination process. This substantiates the need to control and minimize temperature effects, e.g., using 3D printers with a thermostatically-controlled chamber.Conclusion. The conducted analysis of possible causes of misalignment emergence determines the significance of temperature gradients that occur during 3D printing. The proposed manufacturing method allows the printed part of the product to be removed and further returned into the printing process, which can be used to produce PCB prototypes with three conductive layers.

Study of the future economists’ readiness to use artificial intelligence based on the hierarchy analysis method

Introduction. The article examines the problem of increasing the level of digital literacy of future economists in the context of interaction with artificial intelligence systems. The purpose of the study is to assess the readiness of future economists to use artificial intelligence in the context of digital prospects of the socio-economic space. Materials and Methods. The methodological basis of the study is the sustainable development strategy, which identifies educational opportunities, resources and technologies as a global driving force for achieving the Sustainable Development Goals. The main research method is T. Saaty’s Analytical Hierarchical Process method, which enables to build a flexible hierarchical model for studying the dynamics of future economists’ readiness to use artificial intelligence in the context of developing digital literacy. The authors conducted an online survey of students from the Financial University under the Government of the Russian Federation, Astrakhan State University, Omsk State Technical University, and schoolchildren from economics classes (Gymnasium 19, Omsk) to assess the future economists’ readiness to use artificial intelligence in the context of the transition to a digital economy. Results. The authors identified gender differences in respondents’ preferences in the use of artificial intelligence: female participants show higher results than the general sample, when choosing one answer about the purposes of personal use of artificial intelligence, and lower, when choosing a combination of answers, male participants show the opposite results, which is explained by the attitude towards risk in terms of gender stereotypes of behavior. When comparing the choice of respondents’ answers for different age groups (16-20 years old), no age peculiarities were discovered, as well as the ambiguous nature of the influence of artificial intelligence on the younger generation of future economists in terms of a decrease in the natural intelligence of young people against the backdrop of digitalization reaching all spheres of life. A high level of awareness of students and schoolchildren regarding the prospects and problem areas of using artificial intelligence in the field of economics and finance was also revealed. Conclusions. The study concludes that future economists are actively interacting with artificial intelligence systems, promoting the formation of digital literacy in the interests of sustainable development.

Prospects for using powders from pumpkin pulp and rose hips in bakery products

Research to study the influence of pumpkin and rosehip powders obtained by infrared drying on sensory characteristics, nutritional value and cost of raw materials for bakery products made from premium grade wheat flour has been carried out at the Department of Technology and Organization of Food Production of Novosibirsk State Technical University. The objects of the study are two types of powders made using infrared drying of pumpkin pulp and rose hips, and products using these herbal additives. A flowchart for producing these powders has been developed and demonstrated. The use of infrared radiation as a drying method allows you to preserve a larger amount of useful substances, including vitamin C. Three samples of products were made with different mass fractions of pumpkin and rosehip powders instead of wheat flour. The introduction of powders into products led to an improvement in the organoleptic parameters of the samples. The appearance has remained virtually unchanged, but the texture has improved, and the taste and smell have acquired a light fruity tint. The optimal mass fraction of powders was 4+4 % relative to the mass of wheat flour, which corresponds to experimental sample 3, which has a more pleasant taste and attractive appearance compared to control sample 1. A comparative analysis of the nutritional value of these samples has been carried out. Sample 3 contained beta-carotene and ascorbic acid absent in the control sample 1. The cost of a raw material set for a product sample with an optimal mass fraction of powders weighing 480 g increased by 6.4 rubles (43.8 %) compared to the control sample and is justified by the presence of pumpkin and rosehip powders increasing the organoleptic properties and nutritional value of the product. The resulting product can be sold to a wide range of consumers with different income levels.

Assessment of quality indicators in construction

Introduction. Ensuring proper quality of construction is one of the pressing challenges of our time. Consumers expect cheap products from developers in the form of commercial or residential real estate that meet all the required quality indicators. Most accidents in monolithic construction occur due to non-compliance with technological procedures at low temperatures. The purpose of the study is to develop a framework for assessing the quality of concrete work at subzero temperatures (during winter work) based on the results of studies of technological parameters of winter concreting, their impact on the quality and safety of erected monolithic structures of industrial and civil buildings (structures).Materials and methods. The study used the method of approximating distributions of random variables, expert estimates, the theory of multiple principles, and mathematical statistics. The experiments were carried out in the laboratories of the Don State Technical University, as well as in the conditions of actual concrete work on a construction site in winter. The work uses a correlation-regression analysis of the dependence of the organizational and technological causes of inconsistencies (factors) and quality indicators of concrete work production. Statistical information on structural damage and collapse of buildings during their operation was processed. To make organizational and technological decisions to improve the quality of concrete work, it is proposed to take the influence of defects on the load-bearing capacity of buildings as an indicator of the quality level.Results. Using practical and expert methods, the most significant reasons (factors) for the occurrence of inconsistencies in the level of quality of concrete work production have been established. Factors have been identified that have the greatest influence on the change in the load-bearing capacity and reliability of buildings and structures being erected when performing the main types of construction and installation work. The nomenclature of technological quality indicators during winter production of concrete work, their influence on quality substantiated, and methods for assessing the quality of winter concreting technology are developed. Quantitative indicators of the quality of construction of monolithic reinforced concrete structures were obtained.Discussion and conclusions. The practical value of the work lies in the development of a methodological tool for creating a regulatory framework for operational construction control of the production of monolithic and prefabricated monolithic construction and installation works under conditions of exposure to low temperatures, as well as for acceptance control of compliance of completed construction projects with quality requirements. Proposals are given for establishing regulatory tolerances, ways to improve the manufacturability of the equipment used, a new method for designing winter concreting technology, and a quality control method focused on ensuring structural safety have been developed. By developing the research, it is further possible to develop methods for calculating technology parameters taking into account technological variability, as well as establish new indicators to regulate the required level of quality and safety of buildings being built.

The article describes the results of an exploratory research on the basis of Volgograd State Technical University. The empirical object of the study was teachers - students of advanced training courses in the field of digital technologies. The purpose of the study is to identify the attitude of teachers to the wide introduction of digital technologies using artificial intelligence in the educational process. It is shown that different age groups of faculty members demonstrate a rather loyal attitude to digital educational tools, which does not depend much on age. This is confirmed not only by the high level of mastery of digital technologies, but also by the effectiveness of their use in the educational process. Adherence to modern digital tools also does not show a noticeable relationship with the scientific and publication activity of teachers.

The article is devoted to the global problem of bullying, which in the 21st century entered a new stage of evolution - cyberbullying (massive online harassment occurring on the global Internet). Despite the great opportunities of the Internet in the field of youth education and access to information, the global network has opened the door to a limitless world of online entertainment, where virtual space can pose a danger to young people in the form of threats, insults and ridicule. The relevance and interest in the problem of cyberbullying among young people is due to the fact that UN experts claim that every 3rd modern teenager has been bullied in the virtual space. The concern of the world community is also caused by the fact that cyber bullying can have serious consequences for the victim, including problems in studies against a background of increased anxiety; decreased self-confidence and self-esteem; isolation from society, and most importantly, the manifestation of depression, anxiety, post-traumatic stress syndrome and even suicide. In this regard, artificial intelligence (AI) can be used to automatically block insults and threats in the Internet space. The article presents the results of an author's survey of first-year full-time students of Volgograd State Technical University (VSTU). The author provides an overview of foreign statistical data on the problems of cyberbullying in various countries, describes methods of combating and preventing cyberbullying, and substantiates the need to use artificial intelligence (AI) in countering and preventing cyber bullying among young people.

Технология изготовления образцов из композитных материалов для проведения лабораторных испытаний

Based on the accumulated experience of the staff of the Institute of Marine Technologies, Energy and Transport of the Astrakhan State Technical University, the development of the production of various parts of ship hulls, elements of main and auxiliary power plants, including various fasteners and stanchions, using additive technology and other methods of forming composite materials has begun. During the implementation of the developed direction, issues arise of reducing the cost, weight of manufactured parts and improving the characteristics of sound absorption, sound insulation, vibration isolation, etc. Despite the fact that adhesives based on epoxy or polyester resin, according to technical documentation, are fast-curing adhesives, they are not applicable for the production of products using three-dimensional printing technologies. for several reasons. The factors preventing the use of materials for the production of such parts are listed: the minimum curing time of one layer of glue under optimal conditions is from one and a half hours or more, which significantly increases the interlayer time interval; the glue layer is not a self-supporting structure due to the fact that it is in a liquid state during the induction period; products made of this adhesive without reinforcement cannot withstand the required dynamic loads. In the process of experimental studies, a number of formulations based on polyester resin with different fillers were obtained, which have the necessary consistency to apply layers on top of the previous one without waiting for curing, and also contain the necessary amount of reinforcing material and other fillers required to solve problems related to vibration isolation and sound insulation.
