The article considers some aspects of opera and choral performance on the example of analysis of the theatrical period of creativity of one of the prominent figures of Ukrainian choral culture, founder of the choir of the State Children’s Musical Theater — People’s Artist of Ukraine, Professor Mykhailo Krechko (1925–1996). M. Krechko as the first chief choirmaster of the theater built his individual principles of work and theatrical traditions inherent in such a unique opera choir. SCMT is the second in the world and the only professional opera and ballet theater in Ukraine for children and youth).The established traditions and peculiarities of the choir’s work in SCMT are analyzed, based on the repertoire of the newly created Theater and the genre range of performances of choir artists (opera, ballet, musical, cantata and oratorio works, a cappella music performance).Formulation of the problem in general. The relevance of the chosen subject is due to the lack of basic scientific research into the life and work of the famous Ukrainian choral conductor M. Krechko. This is the first comprehensive appeal to the activities of an outstanding master of choral work, active propagandist and collector of folk songs, composer, publicist, teacher and music and public figure, who devoted his entire creative life to the development of national choral culture. A separate task is to study and analyze the basis of the traditions of opera and choral performance initiated by M. Krechko during his work at the State Children’s Musical Theater. Also, it is important to systematically study the methodology and means of educating opera choristers on the example of the work of M. Krechko. Analysis of research and publications to solve the problem. General characteristics of the life and work of Mikhail Krechko are examined in the works of O. Bench-Shokalo, M. Kravchuk, A. Lashchenko, L. Mokanu. The issues of choir and opera choir are analyzed in the works of L. Butenko, O. Letychevska, B. Pokrovsky, K. Pigrov, P. Chesnokov, which explores the functioning of the choir and the nuances of managing this process, as well as the work of specialists in the opera house.The problem of the specifics of M. Krechko’s work with the opera choir was not raised in the scientific literature, which determined the relevance of this article. The research materials of the archive of the “Kyiv Municipal Academic Opera and Ballet Theater for Children and Youth” — programs of performances and concerts, reviews; family archival materials of the Krechko family; publications by M. Krechko and devoted to the work of M. Krechko (booklets, articles in newspapers and magazines, author’s books and reference books). Also, below are a number of personal conclusions of the author of the article while working as a choir artist under the direction of M. Krechko.The purpose of the article is to study the life and work of M. Krechko as an opera choirmaster, his methodology and practical implementation of the multitasking of choir artists in a wide range of synthesis of arts in the opera house.Conclusions and prospects for further exploration in this direction. The article explores for the first time the theme of opera and choral performance in the works of the outstanding Ukrainian choirmaster — People's Artist of Ukraine, Professor Mykhailo Krechko. The above facts from archival materials and analysis of the maestro's artistic activity allow to learn more about the master's contribution to the choral art of Ukraine and its important role in the formation of the vector of development of the State Children's Musical Theater. Emphasis is placed on the specifics and universalism of the theatrical choir. Summarizing all the above, we can say that the modern creative life of the choir Kyiv Municipal Academic Opera and Ballet Theater for Children and Youth is fundamentally based on the high artistic principles laid down by the founder of the choir — Mykhailo Krechko. The Maestro’s great love for the Theater Choir, which he called his “swan song”, high performing skills and a wide range of genres of repertoire, education of followers and like-minded people, and deep traditions established by the choirmaster are a strong foundation and guide to new artistic victories.

Проблема и цель. С развитием и широким применением колесной наземной транспортной техники выдвигаются повышенные требования к устройству машин, их управляемости с одновременным упрощением требований к водителю по управлению машиной и обеспечению ее функционирования в широком диапазоне технических возможностей. Целью исследований явилось теоретическое обоснование и практическая реализация способа непрерывного мониторинга состояния накладок тормозных колодок автомобиля КамАЗ. Методология. Разработано микросистемное устройство для контроля состояния тормозной колодки, отвечающее требованиям автоматизации и роботизации. Электрическая схема устройства построена по аналоговой форме с непрерывной регистрацией неэлектрического сигнала о состоянии (толщине износа) накладки в преобразованной электрической форме. Принцип действия сигнализатора состояния тормозной колодки автомобиля построен на использовании явления изменения электрической емкости конденсатора с изолирующей прокладкой между электродами при изменении толщины этого изолятора. Если встроить в керамическую (изолирующую) накладку тормозной колодки металлический электрод, то он образует электрическую емкость с поверхностью тормозимого металлического тела. Это позволяет в качестве изолирующей прокладки использовать изнашивающийся слой фрикционной накладки тормозной колодки. В таком датчике первичным источником информации будет являться непосредственно контролируемый параметр – остаточный рабочий слой фрикционной накладки тормозной колодки Результаты. Разработано индикаторное устройство, позволяющее водителю, находящемуся в кабине автомобиля, не отрываясь от управления осуществлять непрерывный мониторинг состояния тормозных накладок (толщины рабочего слоя) вплоть до критического, при котором дальнейшая эксплуатация транспортного средства становится небезопасной. Заключение. Применение разработанного индикаторного устройства для визуального функционального контроля водителем состояния тормозных колодок автомобиля делает возможным предотвращение нештатных ситуаций, которые могут возникнуть из-за невозможности эффективного использования рабочей тормозной системы автомобиля по причине предельно допустимого или неравномерного износа фрикционных накладок тормозных колодок. Problem and purpose. With the development and widespread use of wheeled ground transport equipment, increased requirements are put forward for the device of machines, their controllability, while simplifying the requirements for the driver to control the machine and ensure its functioning in a wide range of technical capabilities. The aim of the research was the theoretical substantiation and practical implementation of the method for continuous monitoring of the state of the brake pads of the KamAZ car. Methodology. Microsystem device for monitoring the condition of the brake pad, which meets the requirements of automation and robotization. The electrical circuit of the device is built in an analog form with continuous registration of a non-electrical signal about the state (wear thickness) of the pad in a converted electrical form. The principle of operation of the signaling device of the state of the brake shoe of a car is based on the use of the phenomenon of change in the electrical capacitance of a capacitor C with an insulating gasket between the electrodes when the thickness of this insulator changes. If a metal electrode is embedded in the ceramic (insulating) lining of the brake shoe, then it forms an electric capacitance C with the surface of the braking metal body. This allows the wear layer of the brake pad friction lining to be used as an insulating pad. In such a sensor, the primary source of information will be the directly monitored parameter - the residual working layer of the friction lining of the brake shoe Results. Development of an indicator device that allows the driver, who is in the cab of the car, without interrupting control, to continuously monitor the state of the brake linings (thickness of the working layer) up to the critical state, at which the further operation of the vehicle becomes unsafe. Conclusion. The development of an indicator device for visual functional control by the driver of the state of the brake pads of a car makes it possible to prevent abnormal situations that may arise due to the impossibility of effective use of the working brake system of the car, due to the maximum permissible or uneven wear of the friction linings of brake pads.

We consider the task of automated quality control of sound recordings containing voice samples of individuals. It is shown that in this task the most acute is the small sample size. In order to overcome this problem, we propose the novel method of acoustic measurements based on relative stability of the pitch frequency within a voice sample of short duration. An example of its practical implementation using aninter-periodic accumulation of a speech signal is considered. An experimental study with specially developed software provides statistical estimates of the effectiveness of the proposed method in noisy environments. It is shown that this method rejects the audio recording as unsuitable for a voice biometric identification with a probability of 0,95 or more for a signal to noise ratio below 15 dB. The obtained results are intended for use in the development of new and modifying existing systems of collecting and automated quality control of biometric personal data. The article is intended for a wide range of specialists in the field of acoustic measurements and digital processing of speech signals, as well as for practitioners who organize the work of authorized organizations in preparing for registration samples of biometric personal data.

The existing legislation determines the education as "an integral and focused process of teaching and upbringing, which represents a socially important value and shall be implemented so as to meet the interests of the individual, the family, the society and the state". However, even in this part, the meaning of the notion ‘socially significant benefit is not specified and allows for a wide range of interpretation [2]. Yet the more inconcrete is the answer to the question – "who and how should determine the interests of the individual, the family and even the state?" The national doctrine of education in the Russian Federation, which determined the goals of teaching and upbringing, the ways to attain them by means of the state policy regulating the field of education, the target achievements of the development of the educational system for the period up to 2025, approved by the Decree of the Government of the Russian Federation of October 4, 2000 #751, was abrogated by the Decree of the Government of the Russian Federation of March 29, 2014 #245 [7]. The new doctrine has not been developed so far. The RAE Academician A.B. Khutorsky believes that the absence of the national doctrine of education presents a threat to national security and a violation of the right of citizens to quality education. Accordingly, the teacher has to solve the problem of achieving the harmony of interests of the individual, the family, the society and the government on their own, which, however, judging by the officially published results, is the task that exceeds the abilities of the participants of the educational process.  The particular concern about the results of the patriotic upbringing served as a basis for the legislative initiative of the RF President V. V. Putin, who introduced the project of an amendment to the Law of RF "About Education of the Russian Federation" to the State Duma in 2020, regarding the quality of patriotic upbringing [3]. Patriotism, considered by the President of RF V. V. Putin as the only possible idea to unite the nation is "THE FEELING OF LOVE OF THE MOTHERLAND" and the readiness for every sacrifice and heroic deed for the sake of the interests of your Motherland. However, the practicing educators experience shortfalls in efficient methodologies of patriotic upbringing, which should let them bring up citizens, loving their Motherland more than themselves. The article is dedicated to solution to this problem based on the Value-sense paradigm of upbringing educational dynasty of the Kurbatovs [15].

The purpose of the article is to determine the conceptual fundamentals of modern sport system in the Strategy for the Development of Physical Culture and Sports in our country for the period until 2030, using the analysis of the fundamental changes in modern sports and the orientation of population to the values of sports. Methods and organization of the research. Analysis of the problem occurs on basis of the au-thor’s theory of sports, the study of relevant empirical facts, the results of sociological studies, as well as an analytical review of publications. Results and discussion. Analysis of the fundamental changes in modern sports and the orienta-tion of the population to the values of sport activities resulted in substantiation of conceptual provisions on the significance of the number of activities. These activities include development of various models of modern sports; priority of its health and recreational function; organizing sports for health and recreation as a new model of mass sports and as an element of the structure of children and youth sports; implementing sports for health and recreation into the education system for children and youth. Conclusion. Practical implementation of the formulated conceptual fundamentals of the modern sport system in the Strategy for the Development of Physical Culture and Sports for the period until 2030 primarily depends on changing the priorities of the state social policy in the field of sports. Innovative delivery of sport activities resulted in promotion of healthy lifestyle and crea-tive recreational activities of local communities should take the place of the practice of putting forward sports records and victories of a narrow group of people.

The article is devoted to the study of the movement for communist labour at the Tyumen Shipbuilding Plant during the period of the seven-year plan (1959-1965). The authors seek to fill a historical narrative with the particular facts connected with the peculiarities and specifics of such phenomenon as the movement for communist labour. They consider it in the context of microhistory and as the most important element of production routine. The employees of the largest industrial enterprise of Soviet Tyumen — Shipbuilding Plant in concrete historical circumstances came under the spotlight of the authors. The submitted article is written with attraction of a wide range of archival documents, taken from the funds of the State Archive of the Tyumen Region and also funds of the State Archive of Socio-Political History of the Tyumen Region. Having studied the documents the authors come to conclusion that the movement for communist labour had little effect on the production progress of the plant employees.

The aromatization of a wide range of model aliphatic and cycloaliphatic hydrocarbons (ethene, ethane, propene, n-hexane, 1-hexene, methylcyclopentane, cyclohexane, cyclohexene) on copper-containing NaZSM-5 and HZSM-5 zeolites has been investigated. It was established that the degree of aromatization is related to carbenium ion formation and depends on the acid strength and copper content of zeolite. Experiments with copper-containing samples reduced prior to use indicated the possibility to enhance the selectivity to aromatization. The change of the state of Cu2+ ions during catalytic experiments confirmed the assumption about participation of Cu0 simultaneously with the Bronsted acid centers in the dehydrogenation/hydrogenation steps.

This book is an ethnographic study of controversial sounds and noise control debates in Latin America’s most populous city. It discusses the politics of collective living by following several threads linking sound-making practices to governance issues. Rather than discussing sound within a self-enclosed “cultural” field, I examine it as a point of entry for analyzing the state. At the same time, rather than portraying the state as a self-enclosed “apparatus” with seemingly inexhaustible homogeneous power, I describe it as a collection of unstable (and often contradictory) sectors, personnel, strategies, discourses, documents, and agencies. My goal is to approach sound as an analytical category that allows us to access citizenship issues. As I show, environmental noise in São Paulo has been entangled in a wide range of debates, including public health, religious intolerance, crime control, urban planning, cultural rights, and economic growth. The book’s guiding question can be summarized as follows: how do sounds enter and leave the sphere of state control? I answer this question by examining a multifaceted process I define as “sound-politics.” The term refers to sounds as objects that are susceptible to state intervention through specific regulatory, disciplinary, and punishment mechanisms. Both “sound” and “politics” in “sound-politics” are nouns, with the hyphen serving as a bridge that expresses the instability that each concept inserts into the other.

Dense subregion (subgraph & subtensor) detection is a well-studied area, with a wide range of applications, and numerous efficient approaches and algorithms have been proposed. Approximation approaches are commonly used for detecting dense subregions due to the complexity of the exact methods. Existing algorithms are generally efficient for dense subtensor and subgraph detection, and can perform well in many applications. However, most of the existing works utilize the state-or-the-art greedy 2-approximation algorithm to capably provide solutions with a loose theoretical density guarantee. The main drawback of most of these algorithms is that they can estimate only one subtensor, or subgraph, at a time, with a low guarantee on its density. While some methods can, on the other hand, estimate multiple subtensors, they can give a guarantee on the density with respect to the input tensor for the first estimated subsensor only. We address these drawbacks by providing both theoretical and practical solution for estimating multiple dense subtensors in tensor data and giving a higher lower bound of the density. In particular, we guarantee and prove a higher bound of the lower-bound density of the estimated subgraph and subtensors. We also propose a novel approach to show that there are multiple dense subtensors with a guarantee on its density that is greater than the lower bound used in the state-of-the-art algorithms. We evaluate our approach with extensive experiments on several real-world datasets, which demonstrates its efficiency and feasibility.
