Introduction. The relevance of this problem lies in its insufficient study in comparative pedagogy. Modern society in many countries of the world, based on market relations, seeks to create an environment with the widespread use of information technologies, makes high demands on school graduates who must be ready to realistically assess the level of their abilities and social skills, make an informed choice of their future profession, and competently build communication with social institutions and employers. The purpose of the article is to identify and characterize the impact of digital technologies on the competitiveness and vocational education of high school students in the economically developed countries, such as USA and Singapore. Research methodology and methods. Analysis of scientific literature, initiatives and projects in the two studied countries in the field of introducing digital technologies into the practice of vocational education showed the feasibility of introducing new technologies and forms of organizing training. Research results. The article emphasizes that the emergence of new digital technologies and the pandemic in early 2020 have fundamentally changed the usual patterns of behavior and practice in every country. In the United States, in 2020, due to Covid-19, the “Workplace” simulator model has become widespread, allowing high school students to acquire work skills in selected clusters (specialties) as successfully as if they worked in a real workplace, and in Singapore new technology of 3D virtual reality contributed to the acquisition of professional competencies by high school students and to increase their competitiveness. Conclusion.

Problem and aim. The paper deals with the problem of adapting educational video materials for teaching deaf and hard-of-hearing students. The paper is aimed at identifying and justifying the theoretical bases for adaptation of video materials for teaching students with hearing impairment both during in-class learning and self-study. Methodology. The study was conducted at the Centre for inclusive education of Kalashnikov Izhevsk State Technical University, the experiment involved 11 hearing-impaired students majoring in “Mechanical Engineering”. The participants of the experiment were offered short educational socio-cultural videos of equal complexity, while first video was dubbed with subtitles, and the second one – with a sign language translation. In the first part of the experiment, participants were asked to give a brief summary of the material presented in the video in a free form. In the second part of the experiment, participants were asked to answer test questions on the content of video materials related to some details of the material presented. In conclusion, students were asked to answer questions about their preferences for dubbing video materials and the reasons for their choice. Results and discussion. The results obtained during this experiment demonstrate the preferred use of subtitles when adapting video materials for deaf and hard of hearing students. However, when complex abstract concepts appear in the video, subtitles do not make them easier to understand. In this regard, when developing electronic resources that include video materials, it is possible to provide for the combined use of sign dubbing and subtitles.

Packing optimization problems have a wide spectrum of real-word applications. One of the applications of the problems is problem of placement of containers with spent nuclear fuel (SNF) on the storage platform. The solution of the problem can be reduced to the solution of the problem of finding the optimal placement of a given set of congruent circles into a multiconnected domain taking into account technological restrictions. A mathematical model of the prob-lem is constructed and its peculiarities are considered. Our approach is based on the mathematical modelling of rela-tions between geometric objects by means of phi-function technique. That allowed us to reduce the problem solving to nonlinear programming. Today, an important scientific problem is the problem of creating conditions for safe storage of spent nuclear fuel. In the process of creating any dry spent nuclear fuel storage, the following main stages can be identified: site selection, storage design, construction, operation and decommissioning. A full check for compliance of the repository and its elements with these standards usually begins at the design stage. At the stage of site selection, the inspection for compliance with safety standards is carried out only in terms of the impact of the repository as a whole on the environment. This approach cannot be considered fully appropriate, because, taking into account, for example, all the climatic features of the future storage site, it is possible to adjust the thermal storage regimes of spent nuclear fuel. Similarly, it can be considered necessary to analyze and select the shape of the storage site in order to accommo-date the maximum possible number of spent fuel containers. Such a choice, obviously, should be made taking into ac-count the norms of nuclear, radiation and thermal safety, as well as in compliance with technological limitations. The problem of finding the optimal placement of containers taking into account the given technological limitations can be formulated in the form of the problem of optimization of geometric design. Therefore, the purpose of the study is to build a mathematical model of the problem and study its characteristics to develop effective methods of solution. The proposed approach is based on mathematical modeling of relations between geometric objects using the method of phi-functions. This allowed to reduce the solution of the problem to the problem of nonlinear programming.

Published: March 2021

After the first description of OXA-48 type carbapenemase, it has become endemic in Europe, Mediterranean and North African countries in a short time. OXA-48 carbapenemase is the most difficult type to determine and accurate diagnosis is crucial especially in endemic areas.

The CarbaNP test was described as a rapid phenotypic evaluation method of carbapenemases activity. Sensitivity and specifity of this test were high within all carbapenemases genes. In our study, we evaluated the efficacy of CarbaNP test in routine laboratories located in an endemic area of OXA-48 producing Enterobacterales.

A total of 53 Enterobacterales isolates were included in this study. Antimicrobial susceptibility of the isolates to imipenem, meropenem and ertapenem was determined. Polymerase Chain Reaction (PCR) was carried out for the detection of carbapenemases genes (blaKPC, blaNDM, blaBIC, blaIMP, blaVIM, blaSPM, blaAIM, blaDIM, blaGIM, blaSIM, and blaOXA-48). The Carba NP test was performed as in the protocol described previously.

Altogether 31 isolates (58.4%) were blaOXA-48 positive (18 Klebsiella pneumoniae, 8 Escherichia coli, 2 Serratia marcescens, 1 Enterobacter aerogenes, 1 Pantoea agglomerans and 1 Morganella morganii). Among these isolates 3 (5.6%) and 2 (3.7%) isolates were also positive for blaVIM and blaSPM, respectively.

The sensitivity and specifity of CarbaNP test were found 64.5, and 68.2% respectively. It was observed that determination of positive isolates is hard to distinguish and subjective.

The CarbaNP test has suboptimal results and low of sensitivity and specifity for detection of OXA-48 producing Enterobacterales, and not suitable for detection of blaOXA-48 positive isolates in routine laboratories in endemic areas.

The article presents the manner of showing disease and the suffering of a person by Mediaeval narrative sources. The basis for the article are various national chronicles, monastic historiography and hagiography written in the Middle Ages. The analysed works are the lives of Saint Kinga of Poland, Anne of Bohemia, Salomea of Poland and Saint Francis of Assisi, three monastic chronicles written by canons regulars in the monasteries in Kłodzko, Żagań and Wrocław, and chronicles describing the Polish history by Gallus Anonymous, Jan Długosz and Jan of Czarnków. The author describes the attitude of the society towards the ill person and the attitude of the ill towards their suffering. The article presents also the description of disease and the attempt (or the lack of attempt) to provide medical causes of the illnesses. The indication of pathogenesis of the disease is very rare in the medieval narrative sources. The authors of these works often appeal to God in this matter, they look for an explanation in the Lord’s wrath or divine providence. The author of the article shows the differences in presenting the disease in the sources given in the article depending on the kind of works and its purposes.

The Biała Podlaska poviat was almost at the geographical centre of the interwarperiod Second Polish Republic (1918–1939). However, its peripheral position in relation to other Districts of central voivodships resulted in a number of events and processes that were taking place at that time having a slightly different outmode in its territory. The article attempts to present selected aspects of the demographic structure to confront the extent to which the field of interest diverges from the neighbouring areas. Besides a determination of the population of the district, its structure was analysed in terms of age, gender, level of urbanization and structure of employment. Particularly valuable information was obtained through confrontation of data from the 1921 and 1931 censuses in terms of changes taking place among employment in fundamental branches of the economy. The period was also important for the urban population, which is one of the determinants of the level of modernity of society. Presentation of population growth the county and its characteristics in terms of age and gender provided information on the demographic potential of the analysed area. The analysis provided a number of interesting data sets, somewhat corroborating the varied character of the Biała Podlaska district. The information can be used for further research on the history of the district.
SELECTION AN OPTIMAL NUMBER OF VARIABLES IN REGRESSION MODELS USING ADJUSTED COEFFICIENT OF DETERMINATION AS A MIXED INTEGER LINEAR PROGRAMMING PROBLEM
Authors:   Irkutsk State Transport University, Bazilevskii Mikhail
Published: March 2021

When constructing a regression model, the primary problem faced by the researcher is that it is not clear what the equation of connection between the explained and explanatory variables should be. This initial stage of construction the selection of the model structural specification is called. When choosing a regression specification in parallel, the question arises of which explanatory variables should be included in the equation. This is the problem of variables selection in regression models. Its essence is to single out from the set of “candidates” for inclusion a subset of the most informative of them based on some quality criterion. The article is devoted to the problem of variables selection in regression models estimated using the ordinary least squares. The previously proposed approach to selection a given number of variables based on mixed 0–1 linear programming is considered. The unknown parameters in this problem are the beta coefficients of standardized regression and Boolean variables that are responsible for the occurrence of factors in the model. The optimal values ​​of unknown parameters are found on the basis of maximizing the value of the coefficient of determination of regression. Unfortunately, to solve the problem under consideration, it is required to manually set the number of selected factors, which is often impossible to determine in advance. Therefore, the goal was to formalize the problem so that as a result of its solution the optimal number of selected regressors was also determined. For this purpose, the adjusted determination coefficient, depending on the number of model factors, was used as the objective function. As a result, the problem of mixed integer linear programming was formulated. The unknown parameters in it are still beta coefficients and Boolean variables, as well as an integer variable – the number of regressors. Based on data on prices and characteristics of sedans and hatchbacks of the American automobile industry, a computational experiment was carried out confirming the correctness of the developed mathematical apparatus. The problem formalized in this work in the form of a mixed integer linear programming looks more preferable from a computational point of view than the same problem formalized in modern scientific literature as a mixed quadratic linear programming.

Published: March 2021

In the wave of the green computing trend, research has recently intensified on the so-called adiabatic logic, reversible computing, which is supposed to be the basis of quantum computers and bring to a new level of computing power, combined with low power consumption. The basis of this logic is special reversible gates, for example, Fredkin’s gates. Reversibility is a one-to-one correspondence (bijection) between the inputs and outputs of circuits, which means, on the one hand, the possibility of total control of the results of calculations, and on the other hand, the possibility of returning the obtained "energy" quanta for the perform calculations to their source. This approach can significantly reduce the power consumption of computers, as well as increase the reliability of calculations. There are a lot of publications on this topic, however, the development of universal logic modules on such a basis has not been fully considered. The aim of the study is the development and modeling of universal logic modules based on the Fredkin element. In this case, the methods of logical synthesis of a reversible scheme based on a binary Fredkin element, modeling and analysis of billiard calculations are used. The article presents the proposed schemes of the decoder and multiplexer based on the Fredkin element, the "billiard" simulation. The practical significance of the study lies in the fact that the obtained universal logic modules can be used in the synthesis of binary reversible circuits, for example, FPGAs. The performed simulation can be used as examples in practical exercises in the discrete mathematics, mathematical logic, mathematical modeling, and circuitry disciplines.

The article reveals one of the decision support system (DSS) aspects in compensation plan (CP) problems. In particular, in the research simulation modeling is used to establish relations between functioning results of different CP. These results are total production and wage fund. The author claims, that formulas of different CP may be estimated in a different conditions by using simulation modeling, thus specific patterns may be reviled. Having those patterns, DSS in CP problems may be developed. And its predictions will come true with a high probability. The article demonstrates simulation modeling of time-bonus and piecework CP`s. Patterns are described. According to the research piecework CP always has higher total production and wage fund results then time-bonus CP. Moreover, in the article other patterns after more complicated simulation modeling are shown. The main research results are follows. First, models and conditions for simulation. Second, statistics gathered. Third, conclusions about independence of the CP results according to distribution random quantities and preset different constant parameters, The simulation models include several principles. Models formulas are based on well known formulas, common sense, and “economic person” conception which was developed by S. Mill over 200 years ago and widely used in modern world. Moreover, formulas used in simulation models includes increasing/decreasing coefficients in order to consider randomicity of real economy. This random coefficient generated with a different distributions. These are normal, chi square, exponential, gamma. Simulation parameters were set according to economics logic to fit in common sense. Furthermore, different constants of CP`s are taken into account. Thus, over 2,5 billions combinations were considered. After overall simulations, statistics was gained and specific patterns are shown.
MATHEMATICAL MODELING OF CANCELLOUS BONE TISSUE ADAPTATION APPLIED TO THE HUMAN MAXILLODENTAL SYSTEM
Authors:   Perm National Research Polytechnic University, Kichenko Alexander
Published: March 2021

The bone tissue in different parts of the skeleton conforms to Wolff’s law: it aims to become optimal for the loading which acts on the corresponding bone; the bone is remodelling by means of osteosynthesis and resorption mechanisms. The modern problems of biomechanics demand research on the history of formation of bone structures in the course of time at both physiological and pathological loadings. Ever changing loadings of different nature have influence on development and functioning of the trabecular bone tissue. The mandible is one of the most liable to external and internal changes bones. Very often one has to deal with pathological changes caused by incorrect loading of different regions of bone tissue due to dysfunction of a dentition, a temporomandibular joint and so on. For example, the Popov-Godon’s syndrome which connects with tooth loss is accompanied by pathological remodelling of the surrounding bone tissue. Thus, the mathematical modeling of the cancellous bone tissue behavior in the human maxillodental system is one of the most topical problems of biomechanics and medicine. Trabecular bone tissue is a heterogeneous, porous, anisotropic material. Heterogeneity of spongy structure can be described by methods of quantitative stereology. At the same time, structural features of the trabecular bone can be described by means of the fabric tensor. This is possible to implement if there is both a constitutive relation which connects the stress tensor, the fabric tensor, and the strain tensor, and kinetic equations which describe the evolution of the fabric tensor and bone density. An initial boundary value problem on the trabecular bone tissue remodelling is stated. The effective numerical algorithm allowing to solve the problem is developed. This algorithm is implemented as a complex of problem-oriented programs. Verification of the model and identification of its parameters are carried out. All numerical calculations are performed using the ANSYS software. Trabecular bone tissue evolution is demonstrated on the set of model examples when the stress–strain state is changed. The results demonstrate different character of influence of changes of loading conditions on process of structure formation which follows from Wolff’s law.

Published: March 2021

Resumo: Este artigo analisa a trajetória política do ativismo feminista negro no Brasil, os seus repertórios discursivos acerca das intersecções entre gênero, raça e outras categorias sociais em três tempos. O material de análise provém de dois projetos de pesquisa conduzidos entre 2013 e 2019. Os dados apresentados foram coletados de documentos internos e jornalísticos do Movimento de Mulheres Negras, documentos governamentais, conversas informais e entrevistas semiestruturadas com ativistas negras de Belo Horizonte. O artigo está dividido em três seções, correspondentes a fases específicas: na primeira, nos concentramos no processo de autonomização do Movimento de Mulheres Negras nos anos 1980 e analisamos os repertórios utilizados e expressos no Nzinga Informativo. Em seguida, analisamos suas estratégias de advocacy institucional na década de 1990 e início dos anos 2000, período caracterizado pela tentativa de estabelecer canais formais de participação política para as mulheres negras dentro da burocracia estatal e organizações internacionais. Finalmente, discutimos o ressurgimento de mobilizações de rua na década de 2010 e a emergência de dois cenários de mobilização política liderados por jovens ativistas negras no Brasil: (i) a ascensão de uma geração de jovens feministas negras que estão reformulando e/ou criando novos repertórios discursivos e de confronto nas ruas, nas redes e na representação política; e (ii) a crescente presença de mulheres negras exercendo mandatos legislativos, que, neste texto, nomeamos como movimento de “ocupar a política”. Ao analisar esses repertórios, este trabalho pode contribuir para um melhor entendimento das várias estratégias de mobilização política que feministas negras estão empregando no início do século XXI e seu impacto sociopolítico.

Published: March 2021

Resumo O problema que orienta essa investigação pode ser formulado da seguinte maneira: em que medida a crise constitucional, evidenciada nas reformas recentes contra o núcleo inclusivo da Constituição brasileira que compõem o programa “Uma Ponte para o Futuro”, seria também uma crise temporal? A partir de um estudo teórico-conceitual embasado em pesquisa bibliográfica e análise documental, a hipótese defendida aqui é a de que o pano de fundo dessa crise está relacionado com um discurso que instrumentaliza o “tempo histórico” e o “futuro” em si para gerar adesão social a partir da defesa aberta da aceleração, a defesa de um futuro que deve chegar mais rápido. Tal categoria é analisada a partir de uma leitura específica que esse artigo propõe da obra de Hartmut Rosa, no quadro de uma crítica à aceleração que submete os comprometimentos públicos de longa duração da Constituição à tutela da acumulação da riqueza privada e à velocidade do tempo do mercado e da competitividade.

Published: March 2021

Crtical heat flux (CHF) is an important characteristic of nanofluids. The CHF measurements were carried out in nanofluid research at the Center for Applied Nuclear Science and Technology. These measurements are done manually using a variable power supply and a multimeter. However, it was difficult to record the voltage and current due to the sudden break of the wire. In this study, Arduino was used to measure CHF automatically. The voltage is applied to the wire and increases automatically along with the measurement of the voltage and current in the wire. The results of the voltage and current measurements were compared with a multimeter and were not significantly different. It can be concluded that the CHF measurement system using arduino can be used to measure nanofluid CHF.

When calculating the modes of electric networks, an L-shaped circuit is used to replace one phase of the transformer with bringing its parameters to high voltage (HV), neglecting losses in the HV winding. More precisely, they can be taken into account using a T-shaped substitution scheme. In order to determine the error of the use of the L-shaped scheme in comparison with the use of the T-shaped scheme, the method of conditionally constant coefficients (CPC) was used, which was adapted to calculations using the L-shaped substitution scheme. By the method of the CPC, studies of the modes of the module "double-winding transformer - load (DTN)" were carried out in order to determine the error in calculating the total power losses of the transformer when using the L-shaped equivalent circuit in comparison with the T-shaped one. It was shown that the error in calculating losses for a 25 kVA transformer was 2%. The research results presented in this article are recom-mended to be applied in existing electrical networks for a more accurate calculation of modes and losses in transformers when using the L-shaped equivalent circuit
Solution of the Problem of Plate Drying by Electromagnetic Radiation by Green's Function Method

Published: March 2021

An initial-boundary value problem for calculating heat and mass transfer fields in a homogeneous wet plate blown by an air flow and exposed to electromagnetic radiation is formulated. To solve this problem, we developed an original algorithm containing elements of analytical and numerical methods. It is based on the procedure of splitting the process by physical factors. This procedure is used to replace related problems for the temperature and moisture content fields with separate initial-boundary value problems for these fields on successive layers of the difference grid that are separated by small time intervals. Their solutions, in turn, can be constructed by the method of variable separation, which was impossible to apply to the original problem. In this method, solutions are written using the spatially one-dimensional green function of the Neumann problem, which contains eigenvalues and eigenfunctions of the Sturm-Liouville boundary value problem. The ad-vantages of the new computational algorithm in comparison with the known numerical algorithms are considered, and the problems of the theory of electromagnetic drying for which its application can be effective are indicated.

A procedure for numerical solution of the Dirichlet problem for the Laplace equation, which is often re-duced to modeling potential physical fields in homogeneous media, is described. The approximate solution is proposed to be found using a combined meshfree Monte Carlo method and fundamental solutions, which is implemented in two stages. At the first stage, the element of the best approximation in the linear shell of the fundamental solutions of the Laplace equation is determined. At the second stage, the solution is refined using the potential values found by the Monte Carlo method at individual points in the computational domain. Algorithms are given for finding the defining parameters of both methods used to reduce the error. The procedure for evaluating the accuracy of the found approximate solution of the problem is described. An example of calculating the potential distribution in the angular zone under specified boundary conditions using the combined meshfree method is given. The accuracy of the approximate solution is estimated by comparing it with the exact solution. It is shown that the use of the meshfree method leads to a decrease in the error without a significant increase in the computational resources required for its implementation

The relevance of the study is due to the excess of the permissible errors of current transformers in transient short-circuit modes associated with saturation of the cores of current transformers. The latter leads to improper operation of relay protection devices, which can negatively affect the stability of electric power systems and the efficiency of industrial enterprises with a continuous technological cycle, the power failure of which leads to significant economic damage. The aim of this work is to study the parameters of electric power systems that affect the saturation of the cores of current transformers with a closed magnetic circuit in transient short-circuit modes. The object of research is electromagnetic current transformers of accuracy class 10P in electric power systems. The study was carried out using numerical methods for solving algebraic and differential equations, methods of computer modeling of electromagnetic transient processes and functional programming. As a result, the main parameters influencing the nature and intensity of electromagnetic transients in current transformers during a short circuit are noted; it is shown that in transient short-circuit modes, significant errors in the operation of current transformers associated with core saturation are possible; recommended for assessing the compliance of current transformers of accuracy classes 5P, 10P with the conditions for the correct functioning of relay protection devices in transient short-circuit modes, to calculate the time to saturation of current transformers, taking into account the real parameters of the electric power system at the place where current transformers are installed, in addition to the traditional design checking of current transformers by permissible er-rors for the steady state short circuit.

Fact-checking alliances emerged worldwide to debunk political disinformation in electoral contexts because of social concerns related to information authenticity. This study, thus, included the Latin American context in fact-checking journalism studies as a journalistic practice to fight political disinformation. Through analyzing RedCheq, the first fact-checking journalism alliance in an electoral regional context led by Colombiacheck, 11 in-depth interviews were conducted to identify the perceptions of regional fact-checkers regarding the usefulness of this journalistic practice, its achievements, and the key aspects for incorporating fact-checking into the regional media ecosystem. The study results revealed that RedCheq achieved the goal of fighting disinformation, and that fact-checking developed as transformational leverage for the regional media. Regional journalists perceived fact-checking as an element that restores credibility and social trust in regional media as the epistemology of this journalistic practice neglects the power pressure and dissemination of official narratives. Finally, this study highlighted how fact-checking journalism contributes to the democratic quality and civic empowerment in silenced and polarized environments. In addition, it discussed the need to expand fact-checking journalism’s coverage to new geographical areas and improve journalists’ professional competencies and training, thereby enabling them to function as using verification tools based on regional journalists’ requirements.
Cross-Media Alliances to Stop Disinformation: A Real Solution?
Authors: Palomo Bella , Sedano Jon
Published: March 2021

Social networks have surpassed their intermediary role and become gatekeepers of online content and traffic. This transformation has favored the spread of information disorders. The situation is especially alarming in Spain, where 57% of Spaniards have at some moment believed false news. Since 2016, First Draft has promoted several collaborative verification projects that brought together newsrooms to fact-check false, misleading and confusing claims circulating online during presidential elections in several countries. The main objective of this article is to study the collaboration forged between newsrooms in Spain in order to debunk disinformation contents in 2019 under the name of Comprobado (Verified) and the impact of this initiative. Applying a methodological approach based on non-participant observation, interviews, content analysis of reports, scientific articles, books and media archives, we examine the internal uses of this platform, how journalists verified public discourse, the strategies and internal agreements implemented, and the degree of participation of the 16 media involved. Results show that only half of the initiatives begun were transformed into published reports, and the media impact achieved was limited. Finally, we note that the principal reasons for the frustration of the project were its improvised implementation, due to the date of the election being brought forward, and the scant culture of collaboration in the sector. In Spain at least, cross-media alliances are still an exception.

O estudo objetivou avaliar, em um processo industrial de uma usina para a produção de etanol a partir de cana-de-açúcar, alternativas possíveis para a otimização do uso dos recursos hídricos com consequente economia na redução da captação de água sem prejuízo à qualidade do produto, à eficiência do processo de conversão e ao equilíbrio financeiro do processo produtivo. Para tanto, foram analisadas as correntes por meio de balanço hídrico e observadas as perdas de água e energia nos sistemas de captação de água; de vapor/condensado; de coleta e tratamento de águas residuárias; de destilação; de refrigeração; de fermentação; de embebição da cana, de lavagem de gases e recuperação de fuligem. Os resultados indicaram que é possível alcançar uma economia de água de 222,1 m³/h contra um consumo atual avaliado de 579,0 m³/h, representando 38,4% de redução no consumo de água, bem como atingir o consumo de 1,0 m³/ton de cana processada conforme ao limite determinado pelo órgão ambiental paulista. Os ganhos na melhoria dos processos de produção têm potencial para produzir um superávit anual de cerca de nove milhões de reais.
