The Moscow Karaite Community of the Twentieth Century (According to the Memoirs Recorded in the 1990S From the Old-Time Karaites of Moscow)
Authors: Mikhailov Sergei Sergeevich 
Published: January 2023

The Karaites are one of the very small, but at the same time the most interesting ethno-confessional groups that appeared in the second half of the 19th – early 20th centuries. in a number of large cities of Central Russia, including Moscow. The purpose of the article is to acquaint readers and the scientific community with the results of a study of the Moscow diaspora of Karaites. When writing this article, the author primarily relied on field materials collected by him since 1993, by recording the memoirs of Moscow Karaites-old-timers. This ethnic group, whose representatives began to move from the middle of the XIX century. from the Crimea and, partly, Lithuania, professes a heretical stream of Judaism, founded in the 8th century. Babylonian Jew Anan ben David. Initially, the Russian (Crimean and Lithuanian) Karaites considered themselves part of the Jewish world, however, due to certain political reasons, they began to move away from Jewish identity, presenting themselves as a separate ethnic group professing an independent religion. The history of the Moscow Karaite diaspora is a very vivid example of such an evolution. Based on the method of field research, it was revealed that within the Karaite society, which numbered only a few hundred people, there were contradictions that did not contribute to unanimity in the diaspora and its religious parish. After 1989 there were no attempts to revive religious life. The activists of the community continued to develop new (in the author’s opinion – incorrect) assumptions regarding the origin of the Karaite people and their faith. At present, the Karaite diaspora, which never exceeded several hundred people in Moscow, is in the final stage of assimilation.
The Phenomenon of Bilingualism in Udmurt Literature (on the Example of G. E. Vereshchagin’s Works)
Authors: Kamitova Alevtina Vasilyevna 
Published: January 2023

The article describes the phenomenon of bilingualism, expressed in Udmurt literature at the origins of its formation. An analytical insight of this phenomenon is undertaken on the example of the works of the first Udmurt writer G. E. Vereshchagin, namely, on one of his poems. The introductory part briefly describes the various possible forms of a writer's bilingualism, one of which is adopted by the author under study. Several hypothetical versions are proposed to explain the reasons for the Udmurt writer's appeal to self-translation. An analysis of his lullaby “Glaucous, glaucous dovelet!” in Udmurt and its translated version in Russian, carried out by G. E. Vereshchagin himself, is provided. In the course of a comparative study, similarities and differences were found. It is summarized that the formation of a bilingual context in Udmurt literature begins with the works of G. E. Vereshchagin. Through the author's translation, his poetic creativity is also presented to the Russian-speaking reader for the first time. It is revealed that in the translated text the poet successfully embodied the national stylistics and figurative expressiveness inherent in the original. The study of the bilingual creativity of G. E. Vereshchagin contributes to the understanding of the bilingual phenomenon of national literature.

Relevance. The clinical aspects of tick­borne viral encephalitis (TBE) and Lyme borrelliosis (LB) as monoinfections are well known. At the same time, the issues of interaction of pathogens in tick­borne encephalitis – Lyme borrelliosis mixed infection (TBE – LB mixed infection), the effectiveness of specific prophylaxis, their effect on the incidence rate and clinical forms have not been sufficiently studied.Aims. The aim of this work was to study the clinical course of TBE and TBE ­ LB mixed infection in patients with specific prophylaxis of TBE, as well as in its absence.Materials & Methods. Medical history data from 454 patients patients with a confirmed diagnosis of TBE and TBE – LB mixed infection during 2010–2017 were analyzed.Results. The clinical course of the disease in TBE mono­- and mixed infection, as well as the connection of immunization with the clinical forms of the disease are reflected. The dynamics of the registration of clinical forms of TBE and TBE – LB mixed infection for 8 years was shown using regression models. Synchronization of the incidence of focal and meningeal forms in TBE and TBE – LB mixed infection with a statistically significant decrease in the frequency of their occurrence was noted. The incidence of febrile forms in TBE monoinfection, as well as in mixed infections, remained practically unchanged.Сonclusions. It was found that the incidence of severe focal and meningeal forms of the disease in patients with TBE – LB mixed infection was 1.5 times lower, and the proportion of patients with febrile form TBE was statistically significantly higher than in the group of patients with TBE monoinfection, which may indicate a more favorable during TBE ­ LB mixed infection, and overdiagnosis of febrile form TBE in TBE – LB mixed infection. The increase in the rate of vaccination against TBE of the population contributed to a decrease in the number of TBE и TBE – LB mixed infection cases due to severe clinical forms (focal and meningeal).

Relevance. To date, no detailed analysis of the variants of the pathogen circulating at different times on the territory of the Omsk region has been carried out.Aim. Comparative analysis of the diversity of circulating variants of SARS­CoV­-2 based on molecular genetic data, determine the lines and time of their appearance, compare the data obtained with data from the GISAID database.Materials and methods. Genome­wide sequencing of 222 primary and 5 culture (passages on Vero E6 and SPEV cell cultures) samples of SARS­-CoV­-2 from the Omsk region, collected from April 2020 to February 2022, on Oxford Nanopore Technologies and Illumina platforms, was carried out. Genetic lines were determined in Pangolin. The analysis was performed in MEGA7 and BioEdit.Results. 227 genome­wide SARS­-CoV­-2 sequences were obtained. 222 genomes have been uploaded to the GISAID database. The lines to which the samples belong were determined, phylogenetic trees were constructed for various regions of the SARS-CoV­-2 genome, the levels of virus homology were assessed and mutations in the S­protein region were analyzed.Conclusions. According to the data obtained, it is possible to roughly judge the time of the appearance of a particular variant, its consolidation and distribution in the population, and observe the rare mutations and the circulation of some rare lines. To assess the possibility of significant geographically linked changes in the SARS­-CoV­-2 in the Omsk region, the data obtained are insufficient. Virus variants circulating in the region are grouped into one cluster with identical variants from other regions or countries. A more pronounced intracluster differentiation of the lines can be observed when analyzing the RBD region. The situation with COVID­-19 in the Omsk region generally coincides with that in the whole country and the world. However, this does not exclude the parallel occurrence of certain mutations in remote territories from each other.

Published: January 2023

Taking into account the conditions of the functioning of modern business, it is necessary to take into account the constant changes that occur in the process of developing projects in IT companies. Therefore, when creating projects, there is a need for a well-founded choice of project management methodologies, which will allow to quickly solve problems that arise in the process of their creation and will provide an opportunity to ensure high efficiency of project-oriented activities of companies.
The conducted analysis of the methodologies showed that today there are a sufficient number of them, among which there are rigid and flexible ones. Among the hard methodologies, as Waterfall model, V-model, Incremental model, Spiral model, and Iterative model are known. Among flexible methodologies, the Agile model, as well as Scrum and Kanban are most often used. The following flexible methodologies are also known: Lean, eXtreme Programming (XP), Rational Unified Process (RUP), Dynamic Systems Development Model (DSDM), Rapid Application Development (RAD), and Extreme Programming (XP).
It has been determined that most researchers prove in their studies that agile methodologies are more widespread nowadays and are better adapted to the conditions of rapid changes in projects. The only exceptions are those methodologies that apply to certain industries, such as medical, aviation, and others. Such fields involve the use of only brutal methodologies.
The article examines the modern Agile approach to project management, its difference from the traditional approach of the rigid Waterfall methodology or others; the scope of application of Agile; a short story; the advantages and disadvantages of implementation and its use.
The article provides a comparative analysis of the most popular today's flexible Scrum and Kanban methodologies. The roles that are indicated in projects in Scrum and Kanban are considered. The events performed by the teams are also analyzed in more detail.
The article elaborates a block diagram for a justified choice of Scrum or Kanban methodology. The article is based on research on the international and Ukrainian markets of IT companies.
The direction of future research of the authors is to conduct a more detailed analysis and comparison of rigid and flexible methodologies with the aim of using combined forms of project management.

Published: January 2023

The proposed architecture of the identification software system in the form of class and sequence diagrams. The main criteria for assessing the accuracy of speaker identification were studied and possible sources of loss of speaker identification accuracy were identified, which can be used when building a speaker identification system. A software system based on the proposed architecture and previously developed identification algorithms and methods was created.
The following conclusions can be drawn on the basis of the performed research: approaches to the construction of existing announcer identification systems are considered; the main criteria for assessing the accuracy of announcer identification were investigated and the main sources of loss of accuracy during announcer identification were identified; the structural construction of the announcer identification system is considered, taking into account the identified sources of loss of accuracy during announcer identification; the proposed architecture of the speaker identification system in the UML language in the form of class and sequence diagrams; a software system was built that implements the functions of speech signal identification according to the methods and algorithm proposed in previous works.
The software system uses a ranking method based on three different criteria. These include: calculation of the proximity of two-dimensional probability density function curves for the frequency of the main tone and the location in the spectrum of three frequency ranges that are extracted from the speech recorded in the speech signal; calculation of the proximity of the probability density function curves for each of these features separately; calculation of the degree of closeness of the absolute maxima of the formant spectra extracted from the speech recorded in the speech signal.
INFORMATION TECHNOLOGY FOR STATISTICAL CLUSTER ANALYSIS OF INFORMATION IN COMPLEX NETWORKS
Authors: KYRYCHENKO OKSANA 
Published: January 2023

Information technology has been developed, which is used to collect, process and save large volumes of data from the web space. With the help of technology, the statistical characteristics of various segments of the web space and their cluster structure are studied. Two methods are used to find the optimal number of clusters and cluster centers: the well-known k-core decomposition algorithm and a new method developed by the authors. The new algorithm is based on the distribution of eigenvalues of the stochastic matrix, which describes the process of Markov transitions in the system. The clustering process is carried out using the Power iteration clustering algorithm.
With the help of written software (crawler), information is collected on a given segment of the web space. For the studied area, there are statistical characteristics, namely: node degree, clustering coefficient, node probability distributions by input and output connections. Oriented and unoriented graphs of web pages of the studied zones are constructed. By combining the calculated dependencies for the input and output subnets, we can obtain the statistical characteristics of the undirected graphs of the web pages of the web space zones that we are investigating.
For cluster analysis, the optimal number of clusters and cluster centers can be found in 2 ways: by the well-known k-core decomposition algorithm and by using a new method developed by the author. The new algorithm is based on the distribution of eigenvalues of the stochastic matrix, which describes the process of Markov transitions in the system. Using the Rower iteration clustering algorithm, the cluster structure of various segments of the web space is studied.
The advantage of the developed information technology is that with its help one can work with large sets of data collected on the Internet, study their structure and statistical characteristics, and perform the clustering process. To implement the clustering process and find the optimal number of clusters and centroids a new algorithm is suggested. The results of the algorithm indicate high accuracy in determining the optimal number of clusters.

Published: January 2023

<p><em>Tax collection in Indonesia carried out based on the procedures stipulated in the Regulation of the Minister of Finance of the Republic of Indonesia Number 189/PMK.03/2020 concerning Procedures for Implementing Tax Collection on the Amount of Taxes Accrued (“PMK No.189/PMK.03/2020”). In PMK No.189/PMK.03/2020, the Board of Commissioners can be the Tax Bearer of a Limited Liability Company (Perseroan Terbatas “PT”), whereas in Article 32 of Law Number 28 of 2007 concerning General Provisions and Procedures for Taxation, it is not regulated that the Board of Commissioners may become the Tax Bearer. Then, when viewed from Law Number 40 of 2007 concerning Limited Liability Companies as amended by Law Number 11 of 2020 concerning Job Creation, the organ authorized to represent a Limited Liability Company (PT) is the Board of Directors. The problem of this research is how the arrangement of the Board of Commissioners as the Tax Bearer if it is viewed from the applicable laws and regulations. The normative juridical method is the research method used in this research. This research uses secondary data consisting of primary legal sources, secondary legal sources, and tertiary legal sources. </em><em>From the results of this research, it is concluded that the regulation regarding the responsibilities of the Board of Commissioners in PMK Number 189/PMK.03/2020 is an implementation of Law Number 19 of 1997 concerning Tax Collection with Distress Warrant. In addition, the arrangement is in line with the arrangement of the responsibilities of the Board of Commissioners in the Limited Liability Company Law, as reviewed from Article 69 paragraph (3) jo. Article 114 paragraph (3) of the Limited Liability Company Law which regulates the Board of Commissioners is jointly and severally responsible if the resulting financial statements are incorrect and/or misleading. Nevertheless, the Ministry of Finance is deemed necessary to make some improvements to the deficiencies in the provisions of PMK Number 189/03/2020. </em></p><p><em> </em></p><strong><em>Keywords: Board of Commissioners, Tax Law, Tax Bearer, Limited Liability Company, Taxpayer</em></strong>
Philosophical Discussion of Legal and Moral Relationships in Perspective of Natural Law and Legal Positivism

Published: January 2023

<table width="575" border="0" cellspacing="0" cellpadding="0"><tbody><tr><td valign="top" width="365"><p>The relationship between law and morals has become an academic and philosophical debate throughout the ages, especially in the schools of natural law and legal positivism. The school of natural law always relates law and morals in a close, inseparable relationship, like a coin. The law must contain moral values. Meanwhile, legal positivism clearly separates the relationship between law and morals. Thus the law is not at all related to morality, the problem of law contains moral values or not, not the substance and legal issues, the most important thing is that the law is made by a sovereign ruler. Law is separated from non-juridical elements, such as ethics, morals, politics, economics, sociology, and so on. In other words, the law is purified from something that is not law. With the very sharp differences between the two schools of law, the schools of natural law and legal positivism for hundreds of years have never agreed on the relationship between law and morals. Each has a paradigm, method, theory, and a strong philosophical basis in seeing the relationship between law and morals.</p><p><strong><em>Keywords: Natural Law, Legal Positivism, Law and Morals</em></strong></p><p> </p></td></tr></tbody></table>
