In modern synchronization networks, PRC primary synchronization devices have become an integral component necessary to ensure stable operation and long-term accuracy of reference signals. But their high cost and insufficient use to provide only one unit lead to the need to find other options. Frequency standard manufacturers supply PRS as dedicated hardware without redundancy, whereas in modern synchronization networks PRS must be redundant in order to maintain the required quality of the reference signals. The paper considers the possibilities of modernization of the complex of primary devices of the synchronization network using the example of PJSC “Ukrtelecom” and analyzes the features of using the BesTime algorithm. The main advantages of the protocol in ensuring stable and high-quality operation of the synchronization network are considered. The basic principle of operation of the BesTime algorithm is described, as an algorithmic method of PRC reservation during modernization, the basis of the algorithm is the “triangular hat” method, and as a result, the resulting signal with the best characteristics of one of the three nodes is obtained according to the algorithm. It is demonstrated how the use of the algorithm makes it possible to divide a complex network of synchronization channels into simple and well-controlled fragments with equally high quality reference signals.
SOLUTION OF THE REGRESSION PROBLEM OF DEMODULATION OF SIGNALS WITH AMPLITUDE MODULATION OF MANY COMPONENTS
Authors:   Lviv Polytechnic National University, Tsymbaliuk Ivan
Published: June 2023

The article is devoted to the consideration of AMBS features, highlighting the methodology of AMBS signal calculation for presentation in the form of a signal constellation and time graphs, and the use of calculated signals as input data for training a neural network that performs the task of signal demodulation. To represent sets of random values of different symbols of AMBS signals, a method was proposed, the essence of which is the use of Voronoi cells as a way of dividing the space between the points of the signal constellation, which is more efficient from a geometric point of view, compared to how signals are represented in trivial information transmission systems. The theoretical increase in the efficiency of the proposed method was calculated in comparison with the trivial approach assuming a higher efficiency of Voronoi cells as a way to divide the space between points. The described methods and techniques were embodied in the algorithm of the software product, which performs the task of forming the AMBS constellation, creating noisy variations of the signal around the points, recording these variations in a file, which is later used in the training of the neural network. The principle of operation of the software product based on previously formed algorithms is described, the algorithms themselves are described, their effectiveness is evaluated, the design decisions of the software product structure are explained, in particular, attention is paid to flexibility and the possibility of adjustment for specific cases. It is described with what data and in what form the created system operates. The efficiency of the created system was evaluated using relatively high values of added noise in the analyzed signal. Conclusions are drawn regarding ways to maximize system efficiency, and the dependence of accuracy on various model parameters is depicted. The algorithm for assessing the accuracy of the prediction of the neural network was formed, implemented in the form of a subroutine of the software product, the accuracy of the proposed system was evaluated, and conclusions were drawn about the work done.

Authors:   Lviv Polytechnic National University, Yaremchuk I. , Bulavinets T. , Stakhira P. , Fitio V.
Published: June 2023

In this work, plasmon characteristics of nanocomposite materials based on graphene, graphene oxide, and silver nanoparticles have been studied. The effective dielectric constant and absorption coefficient of the nanocomposites based on graphene-silver and graphene oxide – silver depending on the concentration and size of nanoparticles have been calculated. A change in the silver nanoparticles filling factor by 5 percent leads to significant changes in both the real and imaginary parts of the effective dielectric constant of the nanocomposite material. A pronounced absorption peak is observed in the case of graphene-based nanocomposite with a silver filling factor of 0.2. At the same time, the absorption peak can be indicated at a silver filling factor of 0.1 for the graphene oxide-based nanocomposite. The maximum absorption is observed for the nanocomposite material with nanoparticles having a radius of 5 nm in both cases. The researched nanocomposite materials can be successfully used for various organic electronics applications.

Authors: Na’mah Ulin , Qamaria Rezki Suci , Makrufah Hesti Ayu
Published: June 2023

This research is motivated by an increase in data on complaints and acts of violence against women/housewives every year. For this reason, in this article, the author offers efforts to prevent domestic violence through a new perspective, namely Mubᾱdalah (mutuality). Mubᾱdalah is a concept formulated by Faqihuddin Abdul Kodir that can be applied in household life. In this study, the Mubᾱdalah concept is used as an effort to prevent domestic violence. This research is library research, which is research conducted using data sourced from the library. In this study, the author describes Faqihuddin Abdul Kodir's thoughts as the main basis for analyzing the public role of wives in preventing domestic violence. The conclusions obtained are: First, mubᾱdalah offers the concept of preventing domestic violence through three efforts, namely: instilling the mubadalah perspective on married couples, eliminating powerlessness or inequality in women, and changing the structure and culture in society. Second, the role of the wife in the public sphere is very important to prevent or minimize acts of violence in the household due to power relations or unequal relations between wives and husbands. Therefore, wives are encouraged not to depend on their husbands and to have a network of relationships that can become social support. in eliminating powerlessness and inequality of women in the public and domestic spheres.

Authors: Astyanto Achilleus Hermawan , Indarto Indarto , Deendarlianto Deendarlianto
Published: June 2023

The present work briefly investigates liquid/gas countercurrent two-phase flow phenomena which can be specifically found in a mitigation during an accidental scenario in the operation of a nuclear reactor. A comprehensive knowledge on the corresponding phenomena is obviously important to avoid the failure on the cooling mechanism. Here, a pair of fluid containing high viscous liquid/gas flows through a complex conduit representing 1/30 scaled-down of PWR hot leg’s typical geometry. Furthermore, the flow structures were visually observed, while the film thicknesses are extracted by an image processing algorithm through the corresponding optical-tabulated data. The obtained results reveal that a rather sharp decrease in liquid film corresponds to the flow regime transition.

The COVID-19 pandemic may have changed the effects that urban parks have on their users. The purpose of this study was to understand the mental health effects of the pandemic, explore the role of urban parks on human health, and propose future research directions. We conducted a literature review on the impact of the COVID-19 pandemic on the effects of urban parks on human health and well-being. Using five screening criteria, we selected 32 articles published in the Scopus, Mendeley, and Google Scholar databases for analysis. We chose a systematic literature review as the methodology because it allowed the identification of literature relevant to the research questions. We conducted a systematic study based on the characteristics of the selected articles and the operationalization of variables, reported the results, and made recommendations. The results indicated that people went to parks to relieve stress caused by the pandemic, although some were deterred because they perceived risk in visiting public parks and green spaces. Others focused more on the Internet while in green spaces than on taking advantage of park activities Demands for safety, accessibility for all, and interesting environments will force urban parks to change. There were insufficient practical studies offering novel design ideas and examining the health impacts of small, regional urban parks during the pandemic.
Mandrágora
Authors: Benítez Ana
Published: June 2023

La mandrágora es una planta, una solanácea muy toxica que puede producir efectos alucinógenos o paliativos y, en dosis descontroladas, también la muerte. La razón principal por la cual se le concedieron propiedades mágicas o malignas es que su raíz tiene la forma de un cuerpo humano. El rizoma se bifurca y se desvía caprichosamente imitando brazos y piernas, y su color emula al de la piel del hombre. Aquí se citan algunas obras en donde se encuentra presente esta criatura semihumana. Su existencia, sin duda, es uno de los mitos más inquietantes que sigue despertando interés en quien lo conoce. La mandrágora representa la unión de lo humano con lo animal y con lo vegetal, ese temor del ser humano a escaparse del lugar que lo separa de los otros seres que lo acompañan en el mundo, el deseo ferviente de crear vida, aunque dicha creación lleve implícita su propia muerte.

El vampiro de Bosques de las Lomas (de Drácula a Vlad)
Authors: Mata Juárez Oscar
Published: June 2023

Se narran las semejanzas y diferencias entre Drácula, novela gótica de Bram Stoker, y la novela Vlad de Carlos Fuentes. En Drácula, los esfuerzos de Abraham Van Helsing y sus seguidores tienen éxito, terminan con el vampiro. Sin embargo, el triunfo de la luz sobre la oscuridad, del bien sobre el mal no duro mucho. La siguiente generación de creadores, encabezados por Roman Polansky, dejan en sus obras la advertencia al mundo que la semilla de los vampiros se esparce por toda la faz de la tierra y que los muertos en vida continuaran su búsqueda de sangre humana. Y el final de Vlad no es muy distinto: Yves Navarro, tras rechazar la oferta de unirse a los no muertos, sale de la casona del conde sano y salvo, pero tanto su esposa como su hija se quedan dentro, a merced del vampiro.
De perros a bestias: Perros hambrientos de Ciro Alegría
Authors: Rico Medina Samuel
Published: June 2023

Se presentan extractos de la novela Perros hambrientos, de Ciro Alegría Bazán. La intención del autor es reivindicar al indio, víctima de un sistema social opresivo, y rescatar la grandeza humana que los enaltece y de paso humaniza su relación con la naturaleza y por lo mismo con sus compañeros, los animales. La bestialidad de perros humanizados, adaptada a las labores pastoriles, es resultado de factores biológicos desencadenados por situaciones extremas, y sobre todo cuando los hombres campesinos y pastores de sociedades tradicionales dependían de la agricultura de temporal, propias de sociedades “precapitalistas” o de “antiguo régimen” cuando las sequias se presentaban cíclicamente cada medio siglo, lo que provocaba crisis económicas, incubadoras de hambrunas aterradoras que condenaban a la gente a la miseria.

Un lugar en donde la copula y los espejos se multiplican en hombres y bestias y se convierten, por virtud de una voz que nos llega desde las profundidades de nuestro ser, en la vindicada multiplicación del fervor de los panes.
Mitigating Knowledge Management Internal and External Risk Factors: A Literature Review of Best Practices
Authors: Dodla Tori Reddy , Jones Laura Ann
Published: June 2023

Used to store, manage, and leverage information, knowledge management systems are becoming increasingly valuable assets within organizations. Organizations must manage knowledge internally (through knowledge risks) and externally (through reputational risks). We define knowledge risks as internal human, technological, and organizational factors, and reputational risks as the effects of knowledge risks and external perils to reputation, credibility, financial status, and future success. An oversight of either risk type can cause significant damage to an organization. This literature review was a means to analyze, categorize, and offer best practices for mitigating risks within a knowledge management system.

Authors: Daoudi Iman , Farhi Kamilia , Si bachir Abdelkarim
Published: June 2023

The holm oak is a species that forms interesting stands in the Belezma National Park (PNB). Studying it has allowed us to understand it’s ecological and phytoecological characteristics. Despite the importance of this species, individual trees remain exposed to multiple threats. Surveys were carried out at the level of the massifs of Kassrou and Om rkhaa which enabled us to carry out the floristic groups of the Holm oak. The study area is characterized by high floristic diversity, with 120 plant species belonging to 106 genera and 34 families, 46 of which are not included in the list of flora of the Belezma National Park. The most dominant families are Asteraceae (32 species; i.e., 27%) and Fabaceae (13 species; i.e., 11%), which are also families that are frequently found in Algeria, particularly in the Mediterranean region. The study of the phytogeographical spectrum shows that the field stations studied are dominated by the Mediterranean element (75%, 58%). Analysis of the biological types revealed the predominance of hemicryptophytes (30.33%). Therophytes were present with a high percentage at the two study sites (21%, 32%); the disturbance indices were respectively 46%, and 50%, showing high anthropogenic pressure. It is important to take the necessary measures for the preservation and conservation of this precious heritage.
Using electronic record of sales to support fair budgetary allocations across Czech municipalities
Authors: Semerád Pavel , Rogalewicz Vladimír , Barták Miroslav
Published: June 2023

The paper focuses on electronic record of sales, a tool enabling continuous monitoring and control of declared sales of business entities. Such systems have been recently gaining popularity in European countries. The objective of the paper is to analyse the possible use of electronic record of sales for a fairer redistribution of shared taxes according to the place where the taxable income was earned. We do not consider the current situation to be entirely fair, as sales may be realized in the whole territory of the country. However municipalities that help businesses achieve their income are not fairly rewarded for doing so. This usually gives larger municipalities an advantage at the expense of smaller ones. Currently, the tax administration has sufficient technical equipment to be able to identify the place where the revenue was received.

Jetzt ist die Zeit für verstärkten öffentlichen Wohnungsbau
Authors: Dullien Sebastian , Martin Carolin
Published: June 2023

The German construction industry is facing major challenges. Rising interest rates, high material costs and high energy prices have led to a sharp drop in orders and declining building permits. Consequently, capacity utilisation in the construction industry will fall while the shortage of affordable housing increases. This article proposes appropriate instruments for increased public housing construction. We recommend that the federal government supports the federal states and municipalities in the areas of planning, financing and controlling and increases and expands KfW-programmes.

Kommunalfinanzen in Zeiten steigender Zinsen
Authors: Brand Stephan , Salzgeber Johannes
Published: June 2023

Rising interest rates will impact municipal budgets in Germany by increasing the cost of loans and making it more difficult to finance necessary investments in infrastructure and transformation. While most municipalities should have sufficient leeway to deal with higher interest rates, highly indebted municipalities may be strongly affected by rising interest rates. In these municipalities, interest costs are increasing strongly, budgetary margins are narrower anyway, and these municipalities are more dependent on loans to finance their investments. Rising interest rates thus once again reveal the unresolved and fundamental challenges for the municipal financial system in Germany.
Indien: eine Alternative zu China?
Authors: Menkhoff Lukas , Wagner Christian
Published: June 2023

Tensions in the world economy and European worries about too much economic dependence on China put India into focus. 18 % of the world population are living there in a democratic state. However, the overall market size is just one fifth of the Chinese and democracy is getting weaker, according to a European understanding. Still, the Indian economy offers great long-run potential for trade. India regards itself to be on par with Europe and acts independently, similar to China. This should be kept in mind when partnership is aimed for in economic and political affairs.
Schuldentragfähigkeit mit impliziten Staatsschulden – Leitbild oder Irrlicht?
Authors: Priewe Jan
Published: June 2023

Implicit public debt is a calculation based on assumptions that are qualitatively and fundamentally different from explicit public debt, i.e. it cannot be added to the latter. Moreover, they distort the real costs of ageing considerably. This creates a mirage of public debt that drives fiscal policy in the wrong direction like a will-o’-the-wisp. The costs of demographic change are systematically overestimated.

Published: June 2023

A well-functioning education system is characterised by a high level of student achievement and by providing equal opportunities to succeed irrespective of one’s socio-economic background. Using data from standardised achievement tests and on social mobility, we show that the German education system falls short in both dimensions. While achievement rose after the PISA shock in the early 2000s, it has been declining steadily over the past decade. Furthermore, attendance rates for high-track schools (Gymnasium) differ by as much as 60 percentage points across socio-economic groups, illustrating the lack of equal opportunities. We present policy recommendations aimed at addressing the identified shortcomings and improving the current situation.
Haushaltsspielräume des Bundes: Strukturelle Schieflagen lösen sich nicht durch Aufschieben
Authors: Christofzik Désirée I.
Published: June 2023

In recent years, Germany has defused numerous political conflicts through additional financial leeway. Alongside declining interest expenses, high employment, low unemployment and strong corporate profits have led to increased tax revenues and reduced social expenditures. Special funds, reserves and changed accounting practices were used during the crisis years to create buffers. However, there is now a significant structural budget shortfall. The federal government permanently transferred tax revenues to states and municipalities while expenses continue to rise. Addressing these imbalances requires more than short-term solutions; new exemptions or exceptional measures are not the answer.
Brauchen wir IPCEI?
Authors: Wigger Berthold U.
Published: June 2023

An Important Project of Common European Interest (IPCEI) is a program in the EU that allows participating member states to subsidise the research and innovation of private companies. This paper addresses the question to what extent does IPCEI contribute to a better innovation climate. The paper argues that Germany does not need IPCEI. More than direct subsidies, an innovation-friendly climate in Germany necessitates appropriate tax and capital market conditions, robust research universities, reasonable data accessibility and less technology skepticism.

Published: June 2023

The German economy has been hit hard by Russia’s war of aggression against Ukraine. Higher energy prices, weaker global trade and supply chain disruptions have had a profound impact. In addition to this new geopolitical reality, Germany faces rapid demographic changes and the need to manage its transition to a carbon-neutral economy. With the world’s largest integrated single market, a common currency and the European Green Deal, the EU provides a powerful framework for Germany to maintain and renew its prosperity. Deeper integration of the German economy in the EU Single Market, close cooperation with European partners and a strong domestic reform and investment agenda would benefit both Germany and the EU.

Bu çalışmanın amacı, Trakya Bölgesi’nde iklim değişikliğinin buğday bitkisinin verimine etkisini modellemektir. Bu amaçla, çiftçi tarlasından alınan 2020-2021 dönemi buğday verim değeri, aynı yıla ait iklim verileri kullanılarak LINTUL model ile hesaplanan verim değeri ile karşılaştırılarak kalibre edilmiş ve daha sonra HadGEM2-ES ve MPI-ESM-MR küresel iklim modellerinin RCP4.5 ve RCP8.5 senaryolarından elde edilen iklim verileri ile 2031-2040, 2041-2050, 2051-2060, 2061-2070 ve 2071-2080 dönemleri için verim değerleri tahmin edilmiştir. Ekim ve hasat tarihleri değiştirilmeden iki şekilde verim tahmini yapılmıştır: Birincisinde, ortalama en düşük ve en yüksek sıcaklık, solar radyasyon ve yağış değişimi dikkate alınarak verim hesaplaması yapılmıştır. İkincisinde ise solar radyasyon değerleri 2004-2021 dönemi için sabit tutulurken, ortalama en düşük ve en yüksek sıcaklık ve yağış değişimleri hesaba katılmıştır. Birinci yaklaşımda, HadGEM2-ES modelinin RCP4.5 ve RCP8.5 senaryoları için tahmin edilen verim değişimleri sırasıyla %1,5-%7,5 ve -%7,5-%7,5 arasında hesaplanırken, MPI-ESM-MR modeli için yine aynı sırayla %9,0-%13,4 ve %3,0-%16,4 arasında simüle edilmiştir. İkinci yaklaşımda, HadGEM2-ES modelinin RCP4.5 ve RCP8.5 senaryoları için tahmin edilen verim değişimleri sırasıyla %4,5-%9,0 ve -%7,5-%7,5 arasında hesaplanırken, MPI-ESM-MR modeli için yine aynı sırayla %10,4-%13,4 ve %4,5-%19,5 arasında tahmin edilmiştir. Verim tahminlerinde sıcaklık ve yağışla birlikte solar radyasyonun etkisinin de mutlaka göz önünde bulundurulması gerektiği; Türkiye’nin diğer bölgelerinin aksine iklim değişimi ile verimin genelde artış yönünde olacağı tahmin edildiğinden gıda güvencesi için Trakya Bölgesi tarım arazilerinin değişimine izin verilmemesi gerektiği sonucuna varılmıştır.

The patient underwent multiple pericardial drainage procedures and was eventually sent to a pediatric referral center in the city of Salvador. Contrast-enhanced computed tomography images showed a mediastinal mass, which was resected. Postoperative pathology revealed the patient had a KHE. He was also suspected with Kasabach-Merritt syndrome due to consumption coagulopathy. Corticoid therapy and chemotherapy with vincristine were performed. The patient progressed well and was discharged and placed on outpatient follow-up, without recurrence of symptoms. COMMENTS: KHE is rare and aggressive, although with a benign histopathology. It can complicate with consumption coagulopathy, characteristically seen in Kasabach-Merritt syndrome.
Brain-lung-thyroid syndrome: clinical response under methylphenidate hydrochloride therapy

INTRODUCTION: The “brain-lung-thyroid syndrome” is caused by mutations in the NKX2-1 gene, which encodes the thyroid transcription factor 1, and is characterized by widely diverse clinical manifestations: choreic movements, respiratory disorders and hypothyroidism. CASE REPORT: Male patient, 10 years old, son of non-consanguineous parents, being treated for subclinical hypothyroidism with levothyroxine, was referred at 4 years of age for investigation of hypotonia. There were no reports of breathing problems at birth. Investigation for hypotonia (central and neuromuscular) including muscle biopsy was normal. There was a progressive improvement in hypotonia, but the patient developed choreic movements. In view of the new clinical finding, a genetic-molecular study was carried out directed towards the NKX2-1 gene, confirming the diagnosis of “brain-lung-thyroid syndrome”. The patient started treatment with methylphenidate hydrochloride with evident improvement in choreic movements. DISCUSSION: Manifestations related to the NKX2-1 gene may include hereditary benign chorea (HBC), congenital hypothyroidism and neonatal respiratory disorders. Generally, chorea begins in early childhood, in the patient’s first year of life (most common), in later childhood or even adolescence, and progresses into the second decade after which it remains static or (rarely) resolves. Recently, the use of methylphenidate in patients with a mutation in this gene proved to be a possible therapeutic approach to control choreic movements and improve motor coordination in patients affected by this rare disease.

INTRODUCTION: Food is a triggering factor for irritable bowel syndrome (IBS) symptoms. One therapeutic management option that has had beneficial effects is a low-FODMAP diet (acronym for fermentable oligosaccharides, disaccharides, monosaccharides and polyols). OBJECTIVE: To analyze the efficacy and effects of a low-FODMAP diet in pediatric patients with IBS. METHODS: Systematic review using data from PubMed, SciELO and BVS using the descriptors “(Irritable bowel syndrome) AND (FODMAP)”, age filter from 0 to 18 years, in English, Portuguese and Spanish, with a 10-year temporal filter. Duplicate articles, articles not in agreement with the theme and non-scientific work were excluded. RESULTS AND DISCUSSION: 445 articles were found, but only 3 articles were selected among the eligibility criteria. The studies analyzed make comparisons between the test group and the placebo group, or compare children on a typical American infant diet with a reduced FODMAP diet. It is evident that the low FODMAP diet reduces the symptoms of IBS, but it has factors that make it difficult to be practicable, such as: difficulty in being taught and understood, high cost, impact on the intestinal microbiota, presence of side effects such as constipation, in addition to the impact psychological impact of these restrictions for this age group. CONCLUSION: A low-FODMAP diet is a therapy that alleviates the clinical conditions manifested in IBS, but its applicability is limited. More clinical and experimental studies are needed in order to establish whether the benefits of inserting this restrictive diet outweigh the possible harms.

INTRODUCTION: The disease caused by SARS-CoV-2 called COVID-19 has high transmissibility and broad clinical spectrum. OBJECTIVE: To describe the epidemiological profile and clinical manifestations of children infected with the SARS-CoV-2 virus in a referral pediatric hospital. METHODS: This is a descriptive retrospective study, approved by the Research Ethics Council. RESULTS: 139 medical records of children diagnosed with COVID-19 were analyzed. By correlating the clinical outcome of the disease with its classification, the result was that 13% of patients who died had the severe form of COVID-19. 20% of children with mild clinical form and 19% of moderate clinical form were discharged home. When analyzing each of the symptoms with the clinical outcome, there was a statistically significant relationship between myalgia and dry cough symptoms and the discharge home outcome. And when the complications were analyzed: acute respiratory distress syndrome, multiple organ dysfunction and sepsis, they presented significant statistics with the clinical outcome of death and with the severe and critical clinical forms. When symptoms and complications were related to the clinical classification, they found a significant association between symptoms of productive cough and sore throat and the clinical forms: mild and moderate. CONCLUSION: It is necessary to encourage research in order to characterize the various clinical manifestations of this pathology, which may have different forms of presentation and spread knowledge about it, to establish measures for early diagnosis and adequate treatment, with restoration of health. of affected children.

Education is currently one of the most popular services provided by both the state and private individuals. Moreover, school education is directly related both to the student himself and to the student's family as a whole. The family becomes a kind of controller of the quality of educational services, but gradually the education system is commercialized, which is why it is changing. The problem of social practices of parents' participation in school life finally identified itself after 2012, since the adoption of the new law on education, when parents became full-fledged subjects of school management at the legislative level along with the school administration, moreover, the powers of each component became clearly spelled out. It turned out that the schools of Barnaul are open enough for communication, parents evaluate the interaction with the school in a positive way and believe that all the issues and problems they address to the school are solved immediately or almost immediately. As for intra-family interaction, parents devote two or more hours to their children on weekdays. The time that parents can devote to their children directly depends on the work schedule. Parents help elementary school students with homework to a greater extent, participation in high school is minimal. Based on the above questions, it can be concluded that parents are sufficiently involved in the child's life and constantly keep in touch with them, so they can respond to difficulties that arise in the child at school. The most popular ways for parents to interact with the school are parent meetings and online communication.

Published: June 2023

For centuries, world culture has been thinking about the essence of the idea of Eternal femininity, manifested in philosophy and art. The idea of Eternal femininity is formed from a set of concepts that define a Woman, beauty, love, motherhood, chastity, wisdom, harmony. The purpose of the work is to consider the idea of Eternal femininity in the work of a modern Russian poet – A.M. Sharonov. The goal is realized in the process of analyzing the poem "Valentine" dedicated to the poet's wife. The lyrical heroine is the embodiment of femininity for A.M. Sharonov. The research is based on the application of a set of methods ‒ cultural-historical, comparative-historical, method of holistic analysis of a work of art. The scientific novelty of the research lies in the analysis of A. M. Sharonov's poem "Valentina" in the proposed context for the first time. The article proves that the image of Eternal femininity is formed by A.M. Sharonov through the mythological perception of femininity, which has demiurgic features peculiar to a woman by right of her birth as a woman. She is a demiurge because she was created to give birth (= create), for her this is not goal-setting, as for a man, but a given. A. M. Sharonov's woman is not secondary, not passive, not only an object of admiration and worship, but also a subject who energetically carries out life. According to A.M. Sharonov, a Woman contains wisdom, beauty, love, creative power that contributes to the transformation of the world and gives a person the opportunity to ascend to the heights he has chosen, which determines for him the idea of Eternal femininity.
