Tolerance to uncertainty among psychology students as a predictor of adaptation strategy in the COVID-19 pandemic
Authors: Kondrashikhina Oksana A.
Published: June 2021

The aim of the study is to identify the correlation between tolerance/intolerance to uncertainty with coping strategies and mechanisms of psychological protection of the individual in the conditions of adaptation to situations with a high degree of uncertainty associated with the coronavirus pandemic. A positive correlation was established between tolerance to uncertainty and the protective mechanisms of “humor” and “compensation”, and a negative correlation with the mechanism of “omnipotent control”. Increasing the level of tolerance to uncertainty entails: 1) increased levels of regression and withdrawal in uncertain situations; 2) reduced readiness for systematic problem solving and the emergence of an inability to separate emotions about the situation from its cognitive solution; 3) reduced ability to enter into active opposition with uncertainty, reduced ability to humor and positive reassessment of an uncertain situation. In addition, an increase in the level of interpersonal tolerance to uncertainty leads to an increase in the defense mechanisms and used coping strategies (passive aggression, dissociation, projection, displacement, substitution, distancing, etc.), which clearly indicates the perception of an uncertain situation by such students as extremely difficult, threatening, negative. Thus, tolerance to uncertainty is a significant resource for adaptive living by a person in the conditions of uncertainty of the COVID-19 pandemic. Students with a high interpersonal tolerance to uncertainty are the most vulnerable to the uncertainty associated with the COVID-19 pandemic. The practical significance of the study is in the need to form the ability to constructive activity in conditions of uncertainty, which can be implemented in the process of training interventions. Further research may be based on considering the relationship between tolerance to uncertainty and other factors of adaptation to the conditions of uncertainty caused by the COVID-19 pandemic. The relevance of the study is associated with the scarcity of works on the assessment of adaptive resources of the individual in the conditions of uncertainty associated with the COVID-19 pandemic.

Patrones de reasentamiento: una aproximación digital cuantitativa y exploratoria de los exiliados republicanos de primera generación que regresaron a España (1939-2010)
Authors: Escobar Deras Mauricio
Published: June 2021

Esta investigación explora los datos cuantificables de ciento cincuenta y ocho exiliados republicanos de primera generación; según el año de repatriación a España (de 1939 a 2010); y sus opciones de reasentamiento una vez en el país. Los datos obtenidos provienen de la fusión de dos bases de datos; creadas ad hoc; que se consultaron para ver si estos exiliados regresaron a su lugar de nacimiento; después de su período de exilio; o si eligieron una ciudad diferente para reincorporarse a la sociedad española. Las diferencias de género se examinan moderadamente para explorar las diferencias entre las mujeres que optaban por regresar a sus ciudades nativas y los hombres que optaban por lugares diferentes debido a fuerzas externas. Llegamos a una serie de conclusiones que se pueden aplicar al fenómeno del retorno en general; correlacionándose el fuerte vínculo entre el tiempo pasado en el exilio y la probabilidad; o falta de ella; de regresar a la ciudad de origen. De este modo; nos ayuda a discernir la adaptación; o no; a la sociedad española.

ARSENIC AND LEAD BIOACCESSIBILITIES MEASURED WITH A NOVEL REACTOR SYSTEM USING THE MEXICAN STANDARD AND PBET METHODS: COMPARISON WITH IN VIVO AND IN VITRO REPORTED DATA
Authors: García-Rodríguez Thalía , Gutiérrez-Ruiz Margarita Eugenia , Ceniceros-Gómez Agueda Elena
Published: June 2021

Contaminated soils can become exposure routes of elements toxic to human beings. The health risk of a toxic element by ingestion depends on its bioavailability in the gastrointestinal system, measured in vivo or in vitro. This study aimed to use a novel, versatile reactor (gastrointestinal simulation reactor system to determine bioaccessibility -GSRSB-) to measure lead and arsenic bioaccessibility in the gastric and intestinal phases by applying a modified physiologically based extraction test (PBET). Three composite samples of polluted soils with As (0.50 - 3.25%) and Pb (0.02 - 0.10%) and the certified reference material NIST 2710 were analyzed with this GSRSB-PBET method and the NOM-147 Mexican standard method, which uses an end-over-end shaker. All results were compared to one another. The NIST 2710 results were contrasted with those reported in vivo and in vitro by 14 laboratories. The (GSRSB-PBET) gastric phase ranges were 35.9-55.1 % (As) and 59.6-96.1 % (Pb), while (NOM-147) gastric phases were 35.8-60.4 % (As) and 61.0-70.7 % (Pb). The (GSRSB-PBET) intestinal phase ranges were 39.5-46.9 % (As) and 19.9-31.5 % (Pb). The As and Pb compounds and the stirring technique seem to influence bioaccessibility. On the other hand, the comparison of NIST 2710 results with those reported in vitro and in vivo indicated that As and Pb gastric bioaccessibility obtained with GSRSB-PBET falls into the in vivo results range, while NOM-147 results are higher and fall outside the in vivo range, possibly overestimating the risk. Thus, the proposed method is adequate for modifying the current Mexican Standard Method (NOM-147), which only allows the calculation of Pb gastric bioavailability in vitro.

Authors: Nicoletti Carolina F , Noronha Natalia Y , Pinhel Marcela A S , Nonino Carla B
Published: June 2021

Background: Telomere length (TL) shortening process is associated with several known environment and individual determinants. DNA methylation is the most studied epigenetic process and may be associated with TL. We investigated the associations between DNA methylation and TL in peripheral blood. Methods: Methylation wide association study was conducted in 47 women (37.1±8.8 years) with different nutritional status. Association between TL and DNA methylation levels were explored by univariate and multiple linear regression models, corrected by age and Body Mass Index. Corrections for multiple comparisons by Benjamini‐Hochberg test was also performed. WEBGestalt was used to identify pathways that are responsible for regulating TL. Results: We found negative correlations between TL and BMI (r = -0.641; p = 0.001), abdominal circumference (r = -0.622; p = 0.001) and fat mass (r = -0.656; p = 0.001). 44 CpGs sites were associated with TL, independent of age and BMI. The most of these sites were negatively correlated with TL. For the 7 remained sites, DNA hypomethylation were associated with shorter TL. These CpGs were related to nine different pathways, including thermogenesis, cancer, glutamatergic and serotonergic synapse. Conclusion: There is an epigenetic contribution in TL, independent of nutritional status and age. Genes related to TL are involved in important metabolic pathways.

Published: June 2021

After the arrival of a new airborne virus to the world, science is aiming to develop solutions to withstand the spread and contagion of the SARS-CoV-2 coronavirus. The most severe among the adopted measures is to remain in home isolation for a significant number of hours per day, in order to avoid the spreading of the infection in an uncontrolled way through public spaces. Recent literature showed that the major route of transmission is via aerosols produced especially in poorly ventilated inner spaces. With regard to contagion rates, accumulated incidence or number of hospitalizations due to COVID-19, Spain has reached very high levels, therefore this article develops a quantitative and qualitative analysis of the requirements established in Spain with respect to the European framework in reference to ventilation parameters indoors. For this, a case study has been analyzed, representing a common residence in current Spanish residential developments. Results show that the criteria established in the applicable regulations are not sufficient to ensure health as well as to avoid contagion by aerosols indoors.

Nonlinear sociodynamics of competitive sociotypes of molecular and cosmic human
Authors: Kolesnikov Andrey Vitalievich
Published: June 2021

As one of the most important factors determining the nature of the dynamic behavior of a social system, the article considers the competitive relationship of two alternative sociotypes, conventionally designated as molecular human and cosmic human. The molecular sociotype is understood as the personality of the average consumer, whose behavioral determinants are largely determined by the selfish gene. The cosmic human is a person who has realized the dependence on the selfish gene. Representatives of the cosmic sociotype consider the products of their own mind, their contribution to culture, as a more significant function than gene replication. This explains the different values ​​of the coefficients of reproduction of the total resource of the system by molecular human and cosmic human. Three possible scenarios for the evolution of a social system have been identified for different values ​​of the coefficients of reproduction of the total resource of the system by both sociotypes with a constant share of the population. In this case, the aggregate resource is understood as the entire intellectual, cultural and economic product produced by the social system during a certain conditional cycle of reproduction. The dynamics of a social system with a variable value of the share of a productive comic sociotype is considered in the work on the basis of a nonlinear two-dimensional model. The mathematical model demonstrates complex nonlinear quasicyclic behavior.
Good and bad luck of a computer project
Authors: Malinetskii Georgii Gennadyevich
Published: June 2021

A computer project in the world and in Russia is now usually viewed as an economic, technological or military one. At the same time, it is a global social project. From the theory of the humanitarian and technological revolution, it follows that at the current point of bifurcation, its results can determine the path of humanity to the future. I show that the results of this project reflect the readiness of civilizations for socio-technological change. The COVID-19 pandemic turned out to be a test for social imperatives and had a huge impact on computer reality in the formation of a new sociality. Book by K. Schwab, T. Mallerert “COVID-19: The great reset” represents a variant of such sociality. The analysis presented in this work shows the unacceptability of the proposed changes for the world of Russia. A study of large-scale computer projects in Russia and Belarus shows the need to bring them to a new sociocultural level, much higher than the current one. The unsuccessful experience of mass e-education in the Union State confirmed the imperative of Norbert Wiener: “Render unto man the things which are man’s and unto the computer the things which are the computer’s”. This should, apparently, be a reasonable line of behavior in organizing joint actions of people and machines.

FACTOR ANALYSIS OF THE THERMAL SCHEME OF CHP WITH SUPER CRITICAL STEAM CYCLE ON THE BASIS OF EXERGY METHOD
Authors: Tarasova Victoria
Published: June 2021

The most promising direction of CHP modernization is the introduction of power units on supercritical steam parameters. Increasing steam parameters is one of the most effective ways to increase the efficiency of a CHP plant. Thus, the development of the concept of thermal schemes turbines for supercritical steam parameters, taking into account the characteristics of their operation at the existing CHP Ukraine is an actual scientific problem. The solution to this problem will make it possible to replace or modernize the power generating equipment that has exhausted its resource with modern power units that meet world economic and environmental standards. The method of exergy analysis is adapted to the study of thermal schemes of CHP plants with supercritical steam cycle. As an example of application of a method the exergy analysis of the power plant working on the one-stage thermal scheme is carried out. Within the framework of the proposed method, a thermodynamic and topology-exergetic model of the power plant is created. Based on the topology-exergetic model the indicators of thermodynamic efficiency of the power plant operating on supercritical parameters of steam are determined. It is proposed to apply the theory of experiment planning in exergy analysis of the thermal circuit of a CHP. With the involvement of this theory, a multifactor numerical experiment was conducted to determine the impact on the exergetic efficiency of the thermal scheme of CHP of the main determining variable factors, such as adiabatic and thermal efficiency of the plant, as well as the operating parameters. The generalized equation of functional interrelation of exergetic efficiency of system and exergetic efficiency of elements of thermal scheme of CHP is received. The proposed equation can be used as a tool for further training of neural networks and their application both in the design and in the diagnosis of energy efficiency of CHP. According to the results of the factor analysis, a rather high conservatism of the considered one-stage scheme of CHP to the change of the varied parameters was revealed. This indicates the presence of more rigid structural links between the elements, which is generally a positive aspect of the reconstruction.

The peculiarities of software product testing processes while working in the Scrum-team were studied. The types of testing characteristic of the flexible testing technique are singled out, that make it possible to make the testing process constantly integrated into teamwork, both at the stage of requirements formation and design, and at the stage of coding and generation of test sets. This is possible by making the tester's recommendations in the process of creating user stories, planning the release of the software version in terms of testing and defects, planning a sprint based on user stories and defects, performing a sprint with continuous testing, regression testing after sprint ends and reporting of results of testing. The article highlights the stages of the flexible testing process in the Scrum team. It is proposed to automate the process of flexible testing for a training team project in the Visual Studio software environment based on Team Foundation Server. Author demonstrates an example of automation of the process of flexible testing by dividing it into four quadrants to comply with the principles of working on a flexible methodology of software development. In the first quadrant there is a study of the quality of the internal code of the software product, the modular testing. To implement modular testing in Visual Studio, a new solution is created in order to generate a class for testing, where the conditions for testing are prescribed in the body of the class. The second quadrant implements the principles of system testing. At this stage the features of creating such a test artifact as test cases are demonstrated. That provides for the fulfillment of certain conditions to verify the functionality of the developing software product; linking between created test cases to user stories presented as team project tasks Product Backlog. The study demonstrates an example of manual testing using a special tool Microsoft Test Manager, which allows you to create plans, add and update test cases, perform manual tests. In the third quadrant, it was performed a trial test  in Microsoft Test Manager and it was created another test artifact - error reports. The fourth quadrant automatically tests non-functional software requirements.

Published: June 2021

Technological approaches to the application of functional electrochemical coatings in civil and military technologies are analyzed. It is shown that the existing technical solutions are aimed at solving the problems of strengthening and protection of surfaces and detoxification of environments from pollutants of natural and man-made origin. Electrochemical coatings based on the iron triad, doped with refractory metals, increase corrosion resistance, microhardness and wear resistance of surfaces. Doped with transition metals heteroxide coatings, which are synthesized by the method of plasma electrolytic oxidation on aluminum and titanium alloys have catalytic properties to neutralize toxic substances in the gas and liquid phases. Peculiarities of electrochemical formation of functional coatings on construction materials of different types are investigated. It is shown that cathodic deposition by direct and pulsed current on low-carbon steel and gray cast iron forms uniform ternary coatings of Fe-Mo-W and composite systems of Fe-Co-Mo (Fe-Co-W), which have increased corrosion resistance and mechanical properties compared to base metal material. The obtained thin-layer coatings are recommended for the restoration and strengthening of worn surfaces, in particular in the technology of repair of weapons and military equipment. It was found that plasma-electrolyte treatment of piston silumin in alkaline solutions based on diphosphates synthesized heteroxide systems that are active in reducing the number of toxic emissions of internal star engines and reducing hourly fuel consumption. It is shown that nanocomposite coatings on titanium show photocatalytic activity on the destruction of model pollutants. The obtained materials have a set of enhanced functional properties and are promising for use in industrial and repair production, including the security and defense sector.

Published: June 2021

The market for gluten-free cereal bars as food concentrates and promising food products was studied from the focus of their dietary properties and a functional purpose. The range of grain bars made up 12% of the total food concentrates market in Ukraine and only about 1% of which was devoted to gluten-free grain bars. The main component of both domestic and foreign grain bars included the various products of grain processing. The range of grain bars of domestic and foreign production was analyzed in terms of their component composition and positioning on the market, and then classified into four groups: bars enriched with vitamins; bars with added flavorings and preservatives; bars with sugar substitutes popular among domestic producers; bars with the addition of palm oil, typical for export products. The grain bars of Ukrainian producers were characterized by addition of flax, chia, amaranth, pumpkin, hemp processed products into the composition of gluten bars, but in small quantities. The addition of dried fruits and berries, such as cherries, cranberries, apricots, and grapes, was also popular among domestic manufacturers. Overwhelming majority of the domestic producers used a mixture of four types of cereal flakes as the grain base, namely: oat, wheat, barley and, corn flakes. Taking into account a need in alternative plant resources for the wholesome bars, sorghum, amaranth, flax grain processed products are excellent for the development of gluten-free products. Effect of these non-traditional raw materials (pop sorghum, pop amaranth, flax meal, walnut cake, etc.) on the quality of the grain bars was studied. The use of these ingredients contributed to the enrichment of the grain bars with essential macro-and microelements, lysine, polyphenols, lignin, and vitamins. The developed gluten-free grain bars showed the high consumer qualities; therefore, they are capable to meet the growing demand for gluten-free food products among consumers, providing to widen the range of the grain bars on the Ukrainian market.

Construction of explanations taking into account the dynamics of changes in consumer preferences makes it possible to increase user confidence in the results of the intelligent system. Tasks: structuring models of temporal patterns of parallel-alternative and sequential-alternative users’ choice of the recommendation system; development of a method for constructing patterns of changing user preferences using process mining technology; experimental verification of the method for constructing patterns of changing consumer preferences. The approaches used are: temporal logics, which determine the approaches to the description of the temporal ordering of a set of events. The following results are obtained. The structuring of models of temporal patterns of parallel-alternative and sequential-alternative users’ choice of the recommendation system is performed; developed and performed an experimental test of the method of constructing patterns of user preferences dynamics. Conclusions. The scientific novelty of the results is as follows. The method of dynamics patterns construction of users’ preferences for the formation of explanations concerning the recommended list of subjects is offered. The method sequentially generates a set of ordered events, each of which reflects the choice of the subject by a group of users at a certain time interval, and also builds a graph representation of the patterns of user preferences through intellectual analysis of processes. The patterns obtained as a result of the method consist of time-ordered pairs of events that reflect the knowledge of changing user preferences over time. Further use of such dependencies as elements of the knowledge base makes it possible based on probabilistic inference to build a set of alternative explanations for the received recommendation, and then arrange these explanations according to the probability of their implementation for the recommended list of subjects.
DETERMINING THE LOCATION OF AN UNMANNED AERIAL VEHICLE BASED ON VIDEO CAMERA IMAGES
Authors: Sabziev Elkhan
Published: June 2021

The paper deals with the problem of determining the location of an unmanned aerial vehicle from video and photo images taken by surveillance cameras. As the observation area is considered to be sufficiently limited, the area under consideration can be taken as part of a plane. The solution to the problem is based on the construction of a bijective mapping between the known geographic coordinates of three different objects recognized in the images and their coordinates relative to the monitor plane. To this end, the geographical coordinates of the objects (latitude and longitude) are first converted to the Mercator projection, and a bijective mapping is built between the coordinates of the objects calculated in the Mercator projection and the coordinates relative to the camera monitor plane. Then, based on the current orientation angles of the unmanned aerial vehicle, the coordinates of the projection of its position on the monitor plane are calculated, and the geographical coordinates are found by applying the inverse of the constructed bijective mapping.

The article discusses an approach to technical diagnostics of secondary power supplies for communication facilities. Diagnostics is carried out during the current repair. This takes into account the features of the object being diagnosed, which affect the process of searching for defects. The purpose of the article is to analyze possible options for the development of diagnostic support for secondary power supplies. This takes into account the metrological reliability of measuring equipment. The probability of correct diagnosis is also calculated when searching for defects during routine repairs. Practically implemented recommendations for ensuring the required values of the indicators of the maintainability of communication facilities are substantiated. The possibility and expediency of using effective methods for diagnostics of secondary power supplies of communication facilities, which consider the sources as objects with many inputs, are shown. This allows the design to take into account the requirements for the maintainability of the product. During routine repairs, the time needed to search for defects is minimized. This is done through a rational choice of diagnostic procedures. When choosing, design features and conditions for restoring performance are taken into account. The proposed block diagram of the algorithm for choosing a diagnostic option minimizes the average recovery time of an object. A specific example of using the results obtained in the development of a conditional diagnostic algorithm for the power supply unit of the exciter and the radio receiver of an average power radio station is given. It is advisable to use the results obtained in the development of diagnostic support for promising communication facilities or in the improvement of existing communication facilities without additional costs.

Published: June 2021

The article proposes a model and method of making managerial decisions based on the analysis of geospatial information. The goal of the article is to improve the model and method of making managerial decisions based on the analysis of geospatial information. The results: the algorithm of process of acceptance of the administrative decision which consists of a situational and conceptual part is offered; the algorithm of actions of the head of the organization on the basis of the developed model of acceptance of the administrative decision is offered; the situation when the quality of the decision depends on external factors on which the decision-making body does not influence is considered; the general scheme of a method of acceptance of administrative decisions on the basis of the analysis of the geospatial information is resulted. The methods used are: methods of systems analysis, decision theory, information processing, optimal solutions, probability theory. Conclusions. The model of managerial decision-making has been improved, which, unlike the known ones, is dynamic and is based on the selection of decisions that are optimal by the combined criterion, using predictive values of probabilities of environmental conditions, which ensures the validity of management decisions. The method of managerial decision-making based on geospatial information analysis, which is based on data forecasting and management decision-making models and uses the method of semantic segmentation of species images to assess the a priori probabilities of environmental conditions, further enables decision-making in conditions of risk and uncertainty. The direction of further research is the development of information technology for management decisions based on the analysis of geospatial information.

Problem of structural optimization in a distributed service system is solved by the example of system "Production - delivery - consumption" for mass market product. In this regard, the purpose of work is to develop a method for structural optimization of "Production - delivery - mass consumption" system, by introducing and rational placement of intermediate production points based on solving clustering problems with taking into account the peculiarities of calculating distances between city objects. To achieve the goal of the work, it is necessary to solve the following tasks: clustering of city objects, using the metric of city blocks, for a given number of groups for selected location of production and grouping centers; finding the best location for a given number of clustering centers; determination of a rational number of clustering centers. Task was solved in three stages. First stage - clustering a set of consumption objects for given intermediate delivery centers locations. The second stage - finding the best locations for a given number of intermediate delivery centers. The third stage - determination of the rational number of intermediate centers. Formulated problem is solved according to two criteria: combined length of delivery routes product consumers and the probability that a random delivery time exceeds the critical value. The numerical value of the second criterion is calculated on the assumption that for each path may be estimated value of the mean and variance delivery time. The appropriate number of production centers is determined by a simple comparison of system efficiency for several realistically possible options. An example of clustering problem solving in the metric of "city blocks" on a directed graph by both criteria is given.

The article presents the structure of wood as a fibrous composite made up of cells susceptible to moisture absorption. Attention was paid to the impact of insulation materials on the durability of wood. The flow of moisture in materials such as wood and glass wool representing a group of porous and non-absorbing materials is shown. Microscopic pictures of pine and oak wood, wood fibre mats and glass wool are shown. The full construction of fibers of glass wool and other e. g. mineral wool, makes them extremely non-beneficial for warming partitions in buildings involving wood. Materials with a stable heat conductivity in terms of natural humidity changes in construction works were recommended.
