Wireless ultraviolet cooperative unmanned aerial vehicle formation communication link maintenance method
Authors: Zhao Taifei , Zhao Yi , Liu Kun
Published: August 2022

A stable formation communication network can improve the task efficiency of a unmanned aerial vehicle (UAV) cluster. Aiming at the topology construction of the UAV formation communication network, combined with the optimal rigid graph theory, we design a three-dimensional UAV formation communication network generation algorithm based on the optimal rigid graph. We construct a new link weight function by introducing node residual energy and communication path loss to reduce the overall energy consumption of formation. Aiming at the problem that the communication link of the UAV is interrupted when the formation network is moving, a UAV communication beam tracking and holding method based on a multiple-input multiple-output (MIMO) structure and position prediction is designed. Simulation results show that the network topology constructed by the UAV formation communication network generation algorithm has a good average node degree, and effectively improves the network connectivity and communication fault tolerance. Compared with the tracking and holding algorithm based on the received signal strength, the beam tracking and holding algorithm significantly reduces the number of link interruptions, and the communication success holding rate can be basically maintained at about 90%.

Symbiotic nitrogen fixation (SNF) provides sufficient nitrogen (N) to meet most legume nutrition demands. In return, host plants feed symbionts carbohydrates produced in shoots. However, the molecular dialogue between shoots and symbionts remains largely mysterious. Here, we report the map-based cloning and characterization of a natural variation in GmNN1, the ortholog of Arabidopsis thaliana FLOWERING LOCUS T (FT2a) that simultaneously triggers nodulation in soybean and modulates leaf N nutrition. A 43-bp insertion in the promoter region of GmNN1/FT2a significantly decreased its transcription level and yielded N deficiency phenotypes. Manipulating GmNN1/GmFT2a significantly enhanced soybean nodulation, plant growth, and N nutrition. The near-isogenic lines (NILs) carrying low mRNA abundance alleles of GmNN1/FT2a, along with stable transgenic soybeans with CRISPR/Cas9 knockouts of GmNN1/FT2a, had yellower leaves, lower N concentrations, and fewer nodules than wild-type control plants. Grafting together with split-root experiments demonstrated that only shoot GmNN1/FT2a was responsible for regulating nodulation and thereby N nutrition through shoot-to-root translocation, and this process depends on rhizobial infection. After translocating into roots, shoot-derived GmNN1/FT2a was found to interact with GmNFYA-C (nuclear factor-Y subunit A-C) to activate symbiotic signaling through the previously reported GmNFYA-C-ENOD40 module. In short, the description of the critical soybean nodulation regulatory pathway outlined herein sheds novel insights into the shoot-to-root signaling required for communications between host plants and root nodulating symbionts.

Published: August 2022

Tanzania is HIV-endemic, with 5% prevalence. However, less than half of Tanzanians are aware of their HIV status, and only 75% of adult Tanzanians living with HIV are on antiretroviral therapy (ART). Informal healthcare providers, such as traditional healers, frequently serve as the first line of healthcare in Tanzania. How traditional healers interact with people living with HIV (PLWH) remains unknown. This study sought to understand gaps in HIV care and explore how traditional healers interface with PLWH along the HIV care cascade. We conducted a qualitative study in Mwanza, Tanzania, between November 2019 and May 2020. We invited 15 traditional healers, 15 clients of traditional healers, 15 biomedical healthcare facility staff, and 15 PLWH to participate in a single qualitative interview. Two community focus groups were held with eight male and eight female participants. Participants were 18 years of age or older. Individual experiences with traditional healers and biomedical healthcare facilities, as well as perceptions of traditional healers with respect to HIV care, were explored through interviews. Using a content-analysis approach, codes were grouped into a framework that characterized how traditional healers engage with PLWH throughout the HIV care cascade. PLWH engaged with traditional healers throughout the HIV care cascade, from pre- to post-HIV diagnosis. Traditional healers were described in some cases as facilitating HIV testing, while others were described as delaying testing by providing traditional treatments for HIV symptoms. Traditional medications were frequently used concurrently with ARTs by PLWH. There was concern that healers contributed to ART nonadherence as some PLWH used traditional therapies in search of a “cure” for HIV. Our findings suggest that traditional healers interact with PLWH throughout the HIV care continuum and that collaboration between traditional healers and biomedical healthcare professionals and facilities is needed to improve HIV treatment outcomes.

Traditional Aucan knowledge on fish and plants eaten by fish along the Tapanahoni River, Suriname
Authors: Isabela Pombo Geertsma  , Van der Hoeven Daan , Van Andel Tinde
Published: August 2022

Suriname’s freshwater systems are home to a large diversity of (endemic) fish species, and communities of Suriname’s interior strongly depend on this diversity for their nutrient intake. However, studies on traditional knowledge of the country’s freshwater fish and fish-plant interactions are scarce. Here, we present our findings of a pilot study in the Aucan Maroon community of Diitabiki (Tapanahoni river). We report the species of freshwater fish caught for food, their corresponding Aucan names and plants eaten by fish and/or used for fishing by the local population. We held semi-structured interviews and performed participant observation with fishers and forest guides in August and September 2021. We recorded 14 fish species, of which 12 were identified to species level, and recorded 16 Aucan fish names, of which nine were previously undocumented. Furthermore, we reported 11 plant species that were used for fishing and one fish poison (Tephrosia sinapou (Buc’hoz) A.Chev.). Suriname’s riverine ecosystems are threatened by gold mining activities that endanger the health of local communities, as well as the fish populations and riverine forests on which both people and fish depend. Local knowledge on fish, their feeding behavior and the flooded forests is essential for the conservation of this important Amazonian ecosystem, for the development of sustainable management plans and health education programs on mercury levels in consumption fish.
On the Procedural Status of Officials of the Prosecutor’s Office Participating in Criminal Proceedings
Authors:   Samara National Research University named after S.P. Korolev, Lazareva Valentina , Vershinina Svetlana ,   Togliatti State University
Published: August 2022

Introduction: the paper analyzes some problems of participation in criminal proceedings of officials of the prosecutor’s office, caused by not quite clear regulation of these issues at the level of the Constitution of the Russian Federation, the Federal Law “On the Prosecutor’s Office in the Russian Federation”, the Criminal Procedure Code of the Russian Federation, Orders and Instructions of the Prosecutor General of the Russian Federation. There is an ambiguity in the use of the names of officials of the prosecutor’s office who perform various criminal procedural actions, the lack of a clear division of their procedural powers, forms and principles of interaction. The purpose of the study is to identify the forms of participation of officials of the prosecutor’s office in criminal proceedings, to identify the shortcomings of the legal regulation of procedural statuses, to determine the prospects for the development of the criminal procedure legislation in terms of the registration of the procedural status of officials of the prosecutor’s office. In the course of the research, the methods of both formal-legal and system-structural analysis and synthesis of legal phenomena are used. The results are presented in the form of delegeferenda proposals, taking into account the difference in the procedural statuses of officials of the prosecutor’s office involved in criminal procedural activities in pre-trial and judicial proceedings, on whose basis a model of procedural differentiation of officials of the prosecutor’s office has been developed. The main conclusion is that the procedural statuses of the prosecutor and the state accuser provided for by the current Code of Criminal Procedure of the Russian Federation are not sufficient to cover all forms of participation of officials of the prosecutor’s office in criminal proceedings. In this regard, the proposal is justified to further consolidate the procedural statuses of the superior prosecutor and other participants from the prosecutor’s office.

Published: August 2022

Introduction: the paper provides the answers to the questions concerning the legal status of a convicted person when returning a criminal case to the prosecutor at the stage of cassation appeal against a court decision. The authors reveal the basic concepts affecting the rights of the convicted person, the term of his detention, the grounds entailing the deterioration of the situation of the convicted person and the term allowing such a situation. The purpose of the study: to characterize the features of the legal status of the convicted person when returning a criminal case to the prosecutor at the stage of cassation appeal against court decisions. The objectives of the study: to assess the institution of the return of criminal cases for additional investigation; to analyze the procedural status of the convicted person at the stage of returning the criminal case to the prosecutor during the cassation appeal against court decisions, as well as to offer recommendations for its improvement. Methods: the methodological framework for the study is represented by a set of methods of scientific cognition, among which it is necessary to distinguish the general scientific, systemic, comparative legal and institutional ones. Results: having assessed the materials of the judicial practice, it should be concluded that the court sessions in a significant number of criminal cases returned to the prosecutor have a significant discrepancy between the features of judicial and investigative practice with the legal positions of the Constitutional Court of the Russian Federation; the problems of the legislative regulation of the legal status of the convicted person in the context of the studied issues are identified. Conclusions: the modern criminal process is characterized by legal uncertainty, which leads to a violation of the rights of a person subjected to criminal prosecution in terms of his detention in isolation from society, due to the absence of a formal limitation of such terms. A legal gap is also the fact that neither the Criminal Procedure Code of the Russian Federation nor Resolution of the Plenum of the Supreme Court of the Russian Federation of June 25, 2019, No.19 “On the application of the norms of Chapter 47.1 of the Criminal Procedure Code of the Russian Federation regulating proceedings in the cassation court” contains grounds providing for the deterioration of the situation of the convicted person.
Conceptual Foundations of Denialing the Substantial Character of the Crisis of Culture in Postmodern Theories
Authors:   Volgograd State University, Uglinskaya Nadezhda
Published: August 2022

The article discusses the conceptual foundations of ideas about the crisis that have developed in the postmodern theories. The hypothesis of the study is the assumption that the philosophical grounds of denying of the substantial nature of the crisis of culture in postmodernism include a specific understanding of culture and values, as well as a special attitude to social reality. It is shown that postmodern philosophy is characterized by a new understanding of culture in the meaning of "rhizome" (J. Deleuze and F. Guattari) – a chaotic unstable interweaving of historically changeable values. Since in such a culture the new order is chaos ("chaosmos" (J. Deleuze), the crisis becomes indistinguishable due to the impossibility of distinguishing the ordered from the chaotic. In the absence of a culture with constant values, in a postmodern rhizome culture, the decision to fill the values with content is made by the person himself, which leads to the instrumental and subjective nature of the crisis of culture – to consider a crisis that is convenient at one time or another. Comparison of the classical and postmodernist interpretations of the crisis showed that their difference is associated with a different understanding of the correlative categories of norm / deviation. From the standpoint of classical philosophy, a crisis is a departure from the norm. Accordingly, the crisis of culture is understood as a deviation from the normal (fixed in tradition) functioning of culture. In this regard, it is viewed either in a positive way as a marker of the need for evolutionary transformations, or as a danger threatening culture with destructive consequences. Postmodernism removes the norm / deviation dichotomy. This leads to the conclusion that a negative or positive understanding of the crisis is not characteristic of the methodology of postmodernism. Postmodernists with regard to social reality take a position associated with its replacement by "simulacra" (J. Baudrillard) and the clash of knowledge from different «epistemes» (M. Foucault). For this reason, the crisis of culture as an element of social reality cannot be recognized as a real phenomenon. Social reality is reduced to a narrative about reality by postmodernists. In this regard, the crisis of culture is understood as a discursive reaction to the inevitable withering away of old values, as nothing more than a "pessimistic impression" (J. Lyotard), which consist of the fact that the old universal knowledge legitimation system has outlived, and the new one has not yet was approved. It was revealed that the foundations of denying the substantiality of the crisis of culture in postmodernism are the recognition of the rhizomatic nature of culture, the historicity of values, the denial of social reality as an independent structure of being and its replacement with narratives about reality.
The Tricomi Problem for a Class of Multidimensional Mixed Hyperbolic-Parabolic Equations
Authors:   Institute of Mathematics and Mathematical Modeling of the Ministry of Education and Science of the Republic of Kazakhstan, Aldashev Serik
Published: August 2022

It is known that in the mathematical modeling of electromagnetic fields in space, the nature of the electromagnetic process is determined by the properties of the medium. If the medium is non-conducting, we obtain degenerate multidimensional hyperbolic equations. If the medium has a high conductivity, then we come to degenerate multidimensional parabolic equations. Consequently, the analysis of electromagnetic fields in complex media (for example, if the conductivity of the medium changes) is reduced to degenerate multidimensional hyperbolic-parabolic equations. It is also known that the oscillations of elastic membranes in space can be modeled according to the Hamilton principle by degenerate multidimensional hyperbolic equations. The study of the process of heat propagation in a medium filled with mass leads to degenerate multidimensional parabolic equations. Therefore, by studying the mathematical modeling of the heat propagation process in oscillating elastic membranes, we also arrive at degenerate multidimensional hyperbolic-parabolic equations. When studying these applications, it becomes necessary to obtain an explicit representation of the solutions to the problems under study. Boundary value problems for hyperbolicparabolic equations on the plane are well studied, and their multidimensional analogues are little studied. The Tricomi problem for these equations was previously investigated. As far as we know, this problem has not been studied in space. In this paper, the Tricomi problem is shown to be ambiguously solvable for a class of multidimensional mixed hyperbolic-parabolic equations.

Abstract Background From 1990 to 2015, mortality from aortic aneurysms increased 16.8% in Brazil. São Paulo is the largest city in Brazil and about 5 million people depend on the public health system there. Objectives To conduct an epidemiological analysis of abdominal aortic aneurysm surgeries in the city of São Paulo. Methods Infra-renal aortic aneurysm procedures performed over a decade (from 2008 to 2017) were studied using publicly-available platforms from the Unified Health System and DATASUS. Results 2693 procedures were analyzed; 66.73% were endovascular; 78.7% of patients were male; 70.7% were aged 65 years or more; 64.02% were elective hospital admissions. There were 288 in-hospital deaths (mortality: 10.69%). In-hospital mortality was lower for endovascular surgery than for open surgery; both for elective (4.13% versus 14.42%) and urgent (9.73% versus 27.94%) (p = 0.019) admissions. The highest volume hospital (n = 635) had the lowest in-hospital mortality (3.31%). USD 24,835,604.84 was paid; an average of $ 2,318.63 for elective open, $ 3,420.10 for emergency open, $ 12,157.35 for elective endovascular and $ 12,969.12 for urgent endovascular procedures. Endovascular procedure costs were statistically higher than the values paid for open surgeries (p <0.001). Conclusions Endovascular surgeries were performed twice as often as open surgeries; they had shorter hospital stays and lower mortality.

Beauvoir e a crítica à supervalorização masculina na psicanálise freudiana
Authors: Warmling Diego Luiz , Coelho Mateus Gustavo , Lopes Paula Helena
Published: August 2022

Resumo: Para Freud, a mulher é fortemente influenciada pelo complexo de Édipo negativo, sendo destinada a viver a condição passiva da sexualidade, assim, ele não só não encoraja a autonomia feminina, como descreve a feminilidade tendo por base o modelo masculino. Destarte, a crítica de Beauvoir à psicanálise parte da ideia de que a possibilidade de algo como um destino feminino não existe. A filósofa afirma que a condição de imanência à qual as mulheres se encontram em nossa sociedade, está pautada na socialização à qual são submetidas, privando-as da transcendência. Partindo da leitura da obra de Beauvoir, buscamos compreender melhor a situação das mulheres considerando seus contextos históricos, a fim de reivindicar suas possibilidades ontológicas da liberdade, problematizando o lugar que lhes é imposto pela cultura e reforçado pela supervalorização masculina da psicanálise freudiana.

POLITICAL AND NATURAL SCIENCES: TRANSDISCIPLINARY APPROACH IN TEACHING PROCESS
Authors:   Perm State University, Punina K. A.
Published: August 2022

The transformation of the understanding and implementation of environmental policy in modern Russia brings the need for an interdisciplinary approach to the training of specialists working in this field to the forefront. Civil society is actively involved in the decision-making process on environmental protection. As a unifying principle for politics and ecology, the public ecology that is still being formed in Russia has been chosen. It actively involves society in generating, solving and evaluating these decisions in the political, social and environmental spheres. In the Perm Region, there are frequent cases of integration of experts from the field of ecology and politics to initiate and make management decisions on the environmental agenda and within the framework of sustainable development. This expert community decided to join forces and develop a joint master program "Public Ecology and Public Policy". Graduates of the program will be able to work in state and local authorities responsible for the environmental situation. They will become versatile specialists and will influence management decision-making, justifying them in a reasoned manner. In addition, they will be able to apply their knowledge in the field of environmental consulting, marketing and communications, as well as journalism that reveals the environmental problems of modern society.
A Method for Reducing the Register Effect for Modular Data Formats
Authors:   A Method for Reducing the Register Effect for Modular Data Formats, Inyutin S. A.
Published: August 2022

The substantiation of the author's method of reducing redundancy from the register effect when placing the components of a tuple representing a numerical value in a modular format designed for storage, transmission and processing in modular arithmetic in a specialized SIMD processor of parallel structure is given. Modular coding allows to obtain parallel execution of ring operations in independent computing paths. This, according to Amdahl's law, accelerates the execution of the computational process on multiprocessor computing systems or on multiple cores. Modular data formats are not consistent with the binary bit grid of a multiprocessor computer. In homogeneous binary registers designed to display modulo deductions, redundancy occurs because not all possible binary combinations in a digital register are used to display data. The method is based on the redistribution of the redundancy of digital registers used to display the components of the modular tuple, which allows to reduce to zero the register effect and redundancy of the representation of the components of the tuple. This makes it possible to obtain a dense packing of components of vector modular formats in homogeneous digital registers, which makes the development of SIMD architecture computers processing data in computer modular formats promising. The simulation results allow us to obtain mutually simple bases of the modular number system that meet the conditions of a new patented method for the complete elimination of redundancy.
THE NORMS THAT ESTABLISH THE PROCEDURES FOR COLLECTION OF LOCAL TAXES IN THE STRUCTURE OF THE TAX CODE OF UKRAINE
Authors:   National Technical University Dnipro Polytechnic, Nedostup Kateryna
Published: August 2022

Purpose. The purpose of the article is to substantiate the proposal regarding the placement of legal norms that establish the procedure for collection of local taxes in the structure of the Tax Code of Ukraine. Methods. The quantitative text processing of the text of the Tax Code of Ukraine followed by the interpretation of the results was carried out with the help of content analysis. The formal and legal method was used for the logical processing of legal norms. The comparative method was used when comparing the structure of the code throughout its validity period and the grouping method was used during the division of local taxes and fees depending on the object of taxation. Results. It was substantiated that the legally established definition of the concept of “tax (fee, contribution)” has a tautology of essential features of the direction of mandatory payment. It contains the condition that payers receive a special benefit, which does not correspond to reality, is not fully correlated with rent payments and rent (for land). The words that are not synonyms and have different lexical meanings are identified in the defined concept. The logical definitions of the tax-legal terms such as “tax” and “local tax” which reveal the essence of these mandatory payments were formulated. It was proven that there is no property tax in the tax system. The norms of article 265 of the Tax Code of Ukraine are contrary to common sense – one local tax cannot “consist»” of three local taxes that have different legally established mandatory elements. It was emphasized that today, if business entity has the appropriate property (within the meaning given in article 190 of the Civil Code of Ukraine), it may be a payer of real property tax other than land, transport tax, land tax and parking spaces tax. The object of tourist taxation is not legally established. It was proven that it is a temporary accommodation service received by individual who is a taxpayer in the places of residence (overnight stay), the list of which is given in paragraph 268.5.1 of the Tax Code of Ukraine. It was emphasized that the name and the structure of Section XII of the Tax Code of Ukraine are not consistent with the norms of article 10 and article 265 of this Code. This section of the codified legal act includes the norms that establish the procedure for collection of the tourist tax, which is not taxed on property. Conclusions. The proposed structure of the special part of the Tax Code of Ukraine, which includes the procedures for collection of existing taxes and fees in the tax system, fully complies with the current norms of paragraph 8.1 of article 8, paragraph 9.1 of article 9 and paragraphs 10.1, 10.2 of article 10 of the Tax Code of Ukraine. It provides the opportunity to make additions to the relevant section of the Tax Code of Ukraine in case of the introduction of new national and/or local taxes and fees into the tax system of Ukraine.

Ensuring the investment attractiveness of Russian regions under the influence of international sanctions
Authors: Skornichenko Natalia Nikolaevna
Published: August 2022

Scientists and analysts have been studying the investment attractiveness of Russian regions for a long time. In order to be able to predict the development of regional economy and assess its prospective growth or possible stagnation, it is necessary to assess the investment activity in the country and the investment attractiveness of its subjects. The problem raised is quite relevant at the present time, since most often the main criterion for an investor when determining an investment object is the return on investment, which should be comparable to the level of possible risk from investing capital. Investment attractiveness of Russian regions in 2020-2021 grew, demonstrating a positive trend of change, despite the consequences of the protracted pandemic and the international sanctions imposed in 2014 by the EU and the USA. However, the unprecedented international sanctions imposed by Western countries in 2022 require the development of new strategic decisions, both at the federal and regional levels of government, to ensure the transformation of socio-economic course of development and ensure the investment attractiveness of business entities. The current problem of import substitution in many sectors of Russian economy is also relevant in the investment sphere, first of all, it requires a reorientation of investment flows towards domestic economic entities. In this article, we will consider the issues of the formation of investment attractiveness and the investment climate in the regions of the Russian Federation under the current international sanctions. The destruction of a large economic system always has a negative impact on its investment attractiveness. In this regard, it is advisable to consider the factors of external and internal orientation that affect the investment attractiveness of the region, as well as assess the favorable and negative impact of these factors.
Regulation of the Russian labor market in the new conditions of sanctions impact
Authors: Slatov Dmitry G.
Published: August 2022

The article examines measures to regulate the labor market of the Russian Federation under the conditions of sanctions. The labor market in the new conditions was influenced by a unique combination of diverse economic, political, and social factors. An important feature of the current labor market configuration is the uneven impact of the negative effects of sanctions pressure on various sectors of economy and, as a result, the strengthening of structural imbalances, labor shortages in some sectors and excess in others. Sanctions challenges for the Russian economy have necessitated the need for rapid and adequate support for labor market participants.The article considers legal, administrative and financial measures to support the labor market in new conditions. Measures aimed at stabilizing the labor market and employment are operational and comprehensive, constantly being supplemented as the situation develops. The measures introduced include both administrative and regulatory and financial instruments to support labor market participants, both employees and employers. Special attention is paid to the preservation of human resources in general, and in the field of information technology in particular, as well as the development of entrepreneurial potential of citizens of the Russian Federation. The author suggests maintaining the course of maintaining economic activity of labor market participants, primarily by easing regulatory restrictions and facilitating access to financial resources (subsidies, credit availability, government orders). When making decisions on measures to support the labor market, give preference to complex solutions with high multiplicative and synergistic effects in various areas of the economy and social sphere. In the short term, take measures to ensure supply in order to avoid shortages of goods, ensure price stability and maintain employment in the production and distribution sectors. In the medium term, the main focus should be on maintaining demand from the state, business and individuals (for example, expanding infrastructure projects, supporting housing construction, introducing food certificates for the poor, etc. comprehensive solutions). In the long term, to provide a foundation for the growth of high-tech jobs through the development of machine-tool and mechanical engineering, electronics manufacturing, and other high-tech industries. This growth can be achieved both through the import of technologies and through the support of their own developments. Broad and timely informing of employees and employers about the support measures taken is necessary.
Potential of Russian human capital in the face of sanctions
Authors: Khmeleva Galina A.
Published: August 2022

Human capital research is the main direction of fundamental and applied science. In the face of unprecedented sanctions pressure, building up and strengthening human capital is the most important task of ensuring the sustainability of Russian economy. The article emphasizes the creative role of human capital and analyzes its potential in Russia on the basis of international comparisons. The purpose of the article is to assess the potential of human capital and identify ways to strengthen it under sanctions. It is shown that the key components of the potential of human capital are its physical stock, expressed by quantitative characteristics of the number, age composition, as well as qualitative characteristics, such as the level of education, research and inventive activity. Since the scientific content of the concept of "potential" implies an assessment of the accumulated stock and the possibilities of its use, the article proposes to introduce a population density indicator, which makes it possible to assess the possibilities of future development of territories by attracting human capital. The results of the assessment of human capital have made it possible to note the improvement in the quality of human capital in recent years. However, the sanctions imposed against Russia necessitate accelerated measures to strengthen human capital. To this end, the article proposes a number of appropriate measures that, according to the author, will contribute to the increment of the potential of Russian human capital for the sustainability and innovative development of the economy. The need to promote the resettlement of compatriots not only from the countries of the former USSR, but also from other countries in every possible way was noted. For this purpose, measures are proposed to improve the mechanisms of its implementation.

Currently, the issue of studying the problems of strategic management at the regional level is an urgent direction and this is primarily due to the fact that the effectiveness of regional management directly affects the socio-economic development of this territory. An important function of the management process is planning, which is the process of developing and approving measures aimed at achieving the set goals for the development of the territory, with the fullest use of available and potential resources. In the long term, regional strategic planning becomes more important, which is aimed not only at assessing the current socio-economic state of the subject of the Russian Federation, but also planning its development for the future. Theadoption in 2014 of the Federal Law On Strategic Planning in the Russian Federation defined thepractice of implementing strategic planning at the federal, regional and municipal levels as a tool toimprove the efficiency of the authorities of a particular territory. The purpose of the presented work is to analyze the features of strategic planning as a tool for socio-economic development of the region (using theexample of the Samara region). Proceeding from this, the theoretical aspects of the content of regional strategic planning in the system of tools for improving the socio-economic development of the subject oftheRussian Federation and, as a consequence, increasing the efficiency of the activities of regional tax authorities are important. Methodological aspects of strategic planning at the regional level are related to the development of ways to assess the impact of the effectiveness of strategic planning on the level of socio-economic development of the region, various economic entities and regional authorities. Thepractical aspect of the problem under consideration is related to the development of directions for improving theeffectiveness of strategic planning for the socio-economic development of the region.

Objective. To identify the features of the left heart structure and function in patients with hypertension (HTN) and new onset paroxysmal atrial fibrillation (AF).

Design and methods. We included HTN patients with left ventricular hypertrophy and valid 24-hour Holter monitoring carried out over the last month. Patients without AF paroxysms (age from 37 to 82 years, 38,4% men) were divided into two groups: the 1st group included 32 patients under 55 years of age, the 2nd group comprised 63 patients 55 years of age and older. Thirty-eight patients with AF paroxysms were included in the 3rd group (age from 56 to 74 years, men 28,9%). The parameters of the left heart structure and function, including the global longitudinal strain of the left ventricle and the left atrium strain in the reservoir and contraction phases, were assessed by echocardiography.

Results. The average age of patients in the groups was 44,7 46,4 48,2 vs 61,9 63,7 65,4 vs 63,4 64,8 66,2 years (p < 0,001), and the average duration of HTN was 3,2 4,35,6 vs 6,9 7,99,1 vs 5,7 6,98,1 years (p < 0,001), respectively. The moderate and severe left ventricular hypertrophy and the diastolic dysfunction were found significantly less frequently in the 1st group than in other groups (5,0 12,528,1% vs 43,3 55,667,8% vs 36,8 52,668,5%, p < 0,001 and 5,2 18,832,3% vs 51,6 63,575,4% vs 53,6 68,483,2%, p < 0,001). In 1st group, the left atrial reservoir strain was higher than in the 2nd group, and in the 2nd group it was higher than in the 3rd group (24,7 26,3 28,0 vs 21,5 22,7 23,9 vs 17,8 19,2 20,5, p < 0,001). The left atrial contraction strain did not differ in the 1st and 2nd groups and it was higher than in the 3rd group (13,8 14,9 16,0 and 12,9 13,6 14,2 vs 9,6 10,3 11,1, p < 0,001). The multivariate logistic regression analysis showed that the left atrial strain in the contraction phase is a predictor of AF occurrence in HTN patients over 55 years old depends on. The chances of AF detecting in these patients increase by 3,122 9,21127,171 times (p < 0,001), if the left atrial strain in the contraction phase is below 13%.

Conclusions. The left atrial strain in HTN patients with paroxysmal AF are significantly lower than in patients without cardiac arrhythmias independently of age and the left ventricular state. The left atrial contraction strain ≤ 13% is a predictor of the detection of AF paroxysms during 24-hour Holter monitoring in HTN patients aged 55 years and older.

Objective. Evaluation of the effectiveness and safety of antihypertensive therapy with a fixed dose combination of amlodipine/indapamide in patients with hypertension (HTN) and chronic obstructive pulmonary disease (COPD).

Design and methods. We conducted a non-randomized, open, single-center study, which included 74 comorbid patients (62 men, 12 women) with stage I–II HTN, grade 1–2 HTN, moderate cardiovascular risk and COPD (GOLD I–III). We also assessed respiratory function, the parameters of the microcirculatory bed, vascular stiffness, level of tumor necrosis factor α (TNF-α). For HTN, after the examination all patients were prescribed a fixed combination of amlodipine and indapamide (Arifam, Les Laboratoires Servier, France). The observation period was 6 months.

Results. The study was completed by 58 patients who achieved blood pressure (BP values of 132,7 + 4,8 mm Hg), 54% patients took the initial dose of amlodipine/indapamide was 5/1,5 mg and in 46% patients, the dose of the drug was increased to 10/1,5 mg. After 6 months of treatment, a statistically significant increase in forced expiratory volume in 1st second (FEV1) was detected (p < 0,05), decrease in the average linear velocity along the maximum velocity curve (p < 0,05), Purcelo peripheral resistance index (p < 0,05), pulse wave propagation velocity in the elastic arteries, which was increased at the beginning of the study (p < 0,05), TNF-α (p < 0,05).

Conclusions. The administration of a fixed combination of amlodipine/indapamide in patients with COPD and HTN leads to the achievement of target BP levels, reduction of vascular stiffness, reduction in TNF-α level, improvement of microcirculatory blood flow. The combination is safe and well-tolerated.
