BACKGROUND
Cladophialophora bantiana is a dematiaceous, saprophytic fungus and a rare but reported cause of intracranial abscesses due to its strong neurotropism. Although it predominantly affects immunocompetent individuals with environmental exposure, more recently, its significance as a highly lethal opportunistic infection in transplant recipients has been recognized. Successful treatment requires timely but often challenging diagnosis, followed by complete surgical excision. Next-generation sequencing of microbial cell-free DNA (cfDNA) from plasma is a novel diagnostic method with the potential to identify invasive fungal infections more rapidly and less invasively than conventional microbiological testing, including brain biopsy.

OBSERVATIONS
The authors described the case of a recipient of a liver transplant who presented with seizures and was found to have innumerable ring-enhancing intracranial lesions. The Karius Test, a commercially available method of next-generation sequencing of cfDNA, was used to determine the causative organism. Samples from the patient’s plasma identified C. bantiana 6 days before culture results of the surgical specimen, allowing optimization of the empirical antifungal regimen, which led to a reduction in the size of the abscesses.

LESSONS
The authors’ findings suggest that microbial cfDNA sequencing may be particularly impactful in improving the management of brain abscesses in which the differential diagnosis is wide because of immunosuppression.
Electoral Systems in the Digital Age: Underlying Challenges and New Opportunities. Part ІІ. Constructing the Scales and Algorithms to Determine Integral Rating
Authors: SINYTSKYI M. 
Published: January 2022

The article is devoted to the problem of democratic development of Ukraine.
The reasons for the need for a radical transformation of the electoral process in Ukraine have been considered from a theoretical standpoint. The main goal and sub-goals of the research have been formulated. The classical mathematical models of electoral technologies, selected for comparison with modern approaches have been described.
The basic principles of selection of methods for measuring the results of approval voting have been analyzed. The issues of constructing a verbal-numerical scale, assessing the consistency of voter decisions and applying statistical criteria to obtain a consolidated result have been considered.
The models selected for calculating the final election rating are analyzed. Mathematical algorithms of multicriteria selection based on the qualimetric approach and pairwise comparison on four variants of scales are given. Protocols for determining consensus alternatives using the Topsis method, the Kemeni – Young median, the Schulze heuristic procedure, and the fuzzy set approach are described.
The results of approbation of the selected protocols of approval of the voting system for the election model of 4 candidates on 7 questions of the ballot paper are given. The algorithm and the results of generating by the Monte Carlo method arrays of initial data with a size of 10,000 records, having a uniform and normal distribution with three variants of the bias parameter, are presented. To identify the sensitivity of the studied protocols to violations of the transitivity of individual preference profiles, the primary data arrays were transformed by replacing the nontransitive profiles with an equivalent number of transitive ones without presenting a preference to any alternative. Based on the assessment of the correlation of the final ratings, their sensitivity to the type of distribution and to violations of the transitivity of individual judgments, it was concluded that it is advisable to use the Kemeny median to determine the voting results. The use of the proposed method for transforming primary data also makes it possible to use the Condorcet, Dodgson, Saati and Schulze protocols. The results of this study indicate that there is a fundamental possibility of transition to a new digital paradigm of the electoral process based on the approving principle of voting.

Published: January 2022

Climate change is one of the most serious threats to the society, economy and environment in the whole world and Ukraine in particular. The central objective for the environmental statistics today is to perform the sound statistical assessment, to develop or improve new or existing approaches to building up the system for accounting of the indicators measuring climate change and adaptation to it. The improvement or development of existing or new methodologies and methods for the statistical accounting and assessment of climate change indicators is the only way for the production of information in a sound and comprehensive manner. It is argued that the statistical analysis allows deepening the grasp into the operation of a complex and dynamic phenomena as climate change, elaborate actions to reduce its adverse environmental effect, and eliminate adverse consequences of climate change for our planet.
It is found that the official statistics have been put the ever stronger focus on issues of environmental performance and climate change by concentrating on the development and improvement of methodologies and procedures for compilation of environmental accounts that are used for economic measurements of natural resources, energy, waste, water resources, air emissions, spending for environmental protection. It is stressed the United Nations Statistical Commission has adopted, at global level, the System of Environmental-Economic Accounting (SEEA) designed to provide important support to the development of statistics related with climate change by intensifying the effort in several dimensions of the complex economic and environmental accounting. The industry coverage of the climate change statistics is defined, with a detailed description of various approaches to the environmental accounting in which indicators of climate change are involved. The significance of the environmental-economic accounting (and the account of air emission of dangerous substances in particular) as the central source of data on greenhouse gas emissions in Ukraine is substantiated.
In spite of many functions in the measurement of climate change, assigned to the national statistics system, the existing official statistics does not always employ its capacities for the assessment of climate change. By considering the statistics on climate change as a tool with impact on decision-making in this field, the authors outlined the areas of improvements in the accounting of climate and climate change.
Poland as a Priority Country for the Education Migration of Young Ukrainians
Authors: Cherusheva Н. B. , Parkhomenko V. V. 
Published: January 2022

Intensification of the integration processes in education helps increase the quality of the international education and enhance the striving of youth to receive education services abroad. The economic cooperation of Ukraine with EU countries is gradually taking shape, resulting in the rapidly growing demand of Ukrainian students for education in European higher education establishments (HEEs). The European education system is a global leader in training highly skilled staff due to the implementation of dual training which founder was German. The practice of combined training and internship has spread across Europe and gained extreme popularity in Polish HEEs, thus laying grounds for the increasing demand for their graduates.
In focus of the article is the international education migration of young Ukrainians, first and foremost to Poland, with highlighting the advantages of training in this country that has been recognized as the most optimal one on the European area with respect to professional training. This is due to several reasons: first, the overwhelming majority of Ukrainian graduates from Polish HEEs showed professional competencies and mental fitness for work in companies and enterprises across EU; second, Poland is one of the most attractive foreign partners and investors of Ukraine, which promotes rapid development of collaborative Ukrainian-Polish projects. Poland has been working hard in the latest years to develop and improve the system of education services for foreigners, beginning with language courses for training of professionals with various qualification levels and scientific degrees. The received education services, apart from being an effective means for professional and individual development, can help in the carrier promotion at companies in Poland and beyond. The study covers a social-psychological and economic-statistical analysis of the education migration of Ukraine in the latest years, with determining a range of factors that caused one’s choice of other country for getting education services, and investigating the consequences of Ukrainians’ travels abroad for education purposes.
A Comprehensive Assessment of the Demographic Security of the Republic of Belarus
Authors: Sharilova E. Е. 
Published: January 2022

Security is a necessary component of the life of individuals and society as a whole. One of the most important components of the national security is demographic security, which achievement in the Republic of Belarus means the neutralization of threats such as depopulation, population ageing, degradation of the family institute and unregulated migration processes.
The article presents a methodology for a comprehensive statistical assessment of the demographic security of the Republic of Belarus for 2000–2019, based on of the dualistic approach to the interpretation of this concept, proposed by the author, namely: real and potential demographic security. The real demographic security is the degree of protection from demographic threats in the current social circumstances, which is largely determined by the compliance of government policy with demographic realities.
The proposed methodology for a comprehensive assessment of demographic security includes five consecutive phases: formulating a definition of “demographic security”, identifying demographic threats, building a set of indicators for a comprehensive statistical assessment of demographic security, assessing the effect of demographic threats (general and real), and, finally, assessing the degree of protection from demographic threats (real demographic security).
The structural components of the overall strength of demographic threats are the degrees of real demographic security and the real strength of the threats. The following trend in these values was observed in the Republic of Belarus in 2000-2019: an increase in the degree of real demographic security in parallel with a decrease in the degree of real combined strength of threats in 2015 compared to 2000, giving way to a decrease in the first indicator and an increase in the second one in 2019. It follows that the achievements of the Republic of Belarus in demographic security were short-lived. For a systemic change in the negative trends, it is necessary to form a favorable demographic situation through the active use of educational and propagandist measures.

Published: January 2022

A method for calculating the traction motor of a hybrid transmission of a front-end loader is proposed. It is indicated that these vehicles are characterized by a mode of operation with multiple accelerations and decelerations, as well as alternating operations with high and low required traction force. An electromechanical transmission scheme is proposed. This scheme can be effectively used in such conditions.
The proposed method uses the concept of the magnitude of the range of an electric motor, which can be used to select a specific electric motor that provides the required mobility of the vehicle. For a front loader with a lifting capacity of 3500 kg, a maximum speed of 40 km / h and a maximum specific thrust of 1, the main parameters of the traction motor were determined. However, for the transmission with one fixed gear ratio (EMT1), an electric motor with an excessively high power was obtained. Therefore, the determination of the characteristics of the electric motor for an electromechanical transmission with two fixed gear ratios (EMT2) was carried out. In the process of calculating this transmission, a significantly lower required engine power was obtained.
The article provides an approximate assessment of the energy efficiency of EMT1 and EMT2 transmissions. A method to determine the efficiency of an electric motor depending on its operating mode (on the current angular speed of the shaft and torque) was used. It was determined that the EMT2 transmission has the best efficiency of the electric motor both during bulldozing operation and when driving at maximum speed.
The general conclusion is that it is most rational to use a transmission with two fixed gear ratios. As a further direction of research, the use of computer simulation for evaluating the energy efficiency of a loader in a loading-unloading cycle is highlighted.

Published: January 2022

L
Objective: Stevia rebaudiana Bertoni is a crop that can meet the demand for natural sweeteners; however, this demand requires a sustainable production, as a result of the inclusion of its steviol glycosides or active ingredients in the food and pharmaceutical industries.
Design/methodology/approach: Modern agriculture implies the integrated use of valid natural resources, such as the arbuscular mycorrhizal fungi (AMF). These microorganisms establish a symbiotic relationship with, at least, 80% of the plants, to which they provide multiple benefits. They can directly and indirectly improve crop productivity, through nutrient (particularly, phosphorus) translocation of the soil solution.
Results: As a sustainable alternative for the production of S. rebaudiana, they improve its nutritional state, resulting in a higher biomass production and glycoside concentration —fundamental yield parameters. Additionally, they promote resistance to biotic and abiotic stress factors and improve soil quality.
Limitations/implications: It is worth mentioning that this fungi-plant mutualism is approximately 400 million years-old; however, it has only aroused interest during the last few years.
Findings/conclusions: Although arbuscular mycorrhizal fungi (AMF) are an exploitable resource, their communities are threatened by biotic factors —such as the interaction with other microorganisms— and abiotic factors —which involve bad agricultural practices.
