The 3dp – three-dimensional printing – is it a real prospect of automating the building processes
Authors: Чернєва О.С. , Wojnar Andrzej , Pogan Sara
Published: August 2020

The construction industry is particularly well-suited to take the advantages of the 3DP technology however it still seems to be a distant perspective. The method itself, allows to manufacture prefabricated elements, small landscape facilities and detached houses, pedestrian bridges (of relatively little span lengths) etc. On that field, the considered technology is already prospering. Furthermore, the technology is a great solution for scale models used by architects. The 3-Dimensional print turned out to be a quick and an almost unbeatable way of presenting a concept to the potential investors. The visualization of the project became easier, giving an exact mapping of the surroundings and the structure itself, which helps to eliminate the risk of possible architectural or constructional mistakes. The technology facilitates the implementation of any needed amendments, whereas the scale models became one of the verification ways of the project’s documentation and the building’s proportions. However, more research and law regulations are needed to state the final applicability and limitations of the presented technology. Ensuring the mechanical properties along with the quality control work together to provide us with safe elements for the use of large-scale engineering. The article presents the application of 3D printing technology in construction and bridge engineering. Available technologies and methods of printing objects were presented. Examples of structures made of various materials are presented: concrete, steel and synthetics. The features of an emerging 3-dimensional monolithic objects are conditioned upon the used software advancement, printing technology, the printer used and the material applied. In the mentioned construction industry, where the labour workload becomes an increasingly significant component in the final cost of the construction project, the 3DP could revolutionise the whole process of the execution methodology. The „complexity and universality” of a facility and its execution method is being understood as an increased number of openings, irregular and complex shapes, the precision of the formed elements, fragments or segments and efficiency of the technology used.

A nonlocal boundary-value problem for a fourth-order mixed-type equation
Authors: Fayazov Kudratillo , Khajiev Ikrombek
Published: August 2020

The criterion of uniqueness of a solution of the problem with periodicity and nonlocal and boundary conditions is established by the spectral analysis for a fourth-order mixed-type equation in a rectangular region. When constructing a solution in the form of the sum of a series, we use the completeness in the space L_2, the system of eigenfunctions of the corresponding problem orthogonally conjugate. When proving the convergence of a series, the problem of small denominators arises. Under some conditions imposed on the parameters of the data of the problem and given functions, the stability of the solution is proved.
Matrix boundary-value problems for differential equations with p-Laplacian
Authors: Nesmelova Olga
Published: August 2020

We consider the boundary-value problem for a linear system of differential equations with matrix p-Laplacian, which is reduced to the traditional differential-algebraic system with an unknown in the form of the vector function. A generalization of various boundary-value problems for differential equations with p-Laplacian, which preserves the features of the solution of such problems, namely, the lack of uniqueness of the solution and, in this case, the dependence of the desired solution on an arbitrary function, is given.
Mappings with finite length distortion and prime ends on Riemann surfaces
Authors: Ryazanov Vladimir , Volkov Sergei
Published: August 2020

The present paper is a continuation of our research that was devoted to the theory of the boundary behavior of mappings in the Sobolev classes (mappings with generalized derivatives) on Riemann surfaces. Here we develop the theory of the boundary behavior of the mappings in the class of FLD (mappings with finite length distortion) first introduced for the Euclidean spaces in the article of Martio-Ryazanov-Srebro-Yakubov at 2004 and then included in the known book of these authors at 2009 on the modern mapping theory. As was shown in the recent papers of Kovtonyuk-Petkov-Ryazanov at 2017, such mappings, generally speaking, are not mappings in the Sobolev classes, because their first partial derivatives can be not locally integrable. At the same time, this class is a natural generalization of the well-known significant classes of isometries and quasiisometries. We prove here a series of criteria in terms of dilatations for the continuous and homeomorphic extensions to the boundary of the mappings with finite length distortion between domains on Riemann surfaces by Caratheodory prime ends. The criterion for the continuous extension of the inverse mapping to the boundary is turned out to be the very simple condition on the integrability of the dilatations in the first power. The criteria for the continuous extension of the direct mappings to the boundary have a much more refined nature. One of such criteria is the existence of a majorant for the dilatation in the class of functions with finite mean oscillation, i.e., having a finite mean deviation from its mean value over infinitesimal disks centered at boundary points. As consequences, the corresponding criteria for a homeomorphic extension of mappings with finite length distortion to the closures of domains by Caratheodory prime ends are obtained.
On the estimates of the values of various widths of classes of functions of two variables in the weight space $L_{2,\gamma}(\mathbb{R}^2)$, $\gamma=\exp(-x^2-y^2)$
Authors: Vakarchuk Sergey , Vakarchuk Mihail
Published: August 2020

For the classes of functions of two variables $W_2(\Omega_{m,\gamma},\Psi)=\{ f \in L_{2,\gamma}(\mathbb{R}^2) : \Omega_{m,\gamma}(f,t) \leqslant \Psi(t) \, \forall t \in (0,1)\}$, $m \in \mathbb{N}$, where $\Omega_{m,\gamma}$ is a generalized modulus of continuity of the $m$-th order, and $\Psi$ is a majorant, the upper and lower bounds for the ortho-, Kolmogorov, Bernstein, projective, Gel'fand, and linear widths in the metric of the space $L_{2,\gamma}(\mathbb{R}^2)$ are found. The condition for a majorant under which it is possible to calculate the exact values of the listed extreme characteristics of the optimization content is indicated. We consider the similar problem for the classes
$W^{r,0}_2(\Omega_{m,\gamma},\Psi)=L^{r,0}_{2,\gamma}(D,\mathbb{R}^2) \cap W^r_2(\Omega_{m,\gamma},\Psi)$, $r,m \in \mathbb{N}$, $\big(D=\frac{\displaystyle \partial^2}{\displaystyle \partial x^2} + \frac{\displaystyle \partial^2}{\displaystyle \partial y^2} -2x\frac{\displaystyle \partial}{\displaystyle \partial x} -2y\frac{\displaystyle \partial}{\displaystyle \partial y}$ being the differential operator$\big)$. Those classes consist of functions $f \in L^{r,0}_{2,\gamma}(\mathbb{R}^2)$ whose Fourier--Hermite coefficients are $c_{i0}(f) = c_{0j}(f)=c_{00}(f)=0$ $\forall i, j \in \mathbb{N}$. The $r$-th iterations $D^rf = D(D^{r-1}f)$ $(D^0f \equiv f)$ belong to the space $L_{2,\gamma}(\mathbb{R}^2)$ and satisfy the inequality $\Omega_{m,\gamma}(D^rf,t) \leqslant \Psi(t)$ $\forall t \in (0,1)$. On the indicated classes, we have determined the upper bounds (including the exact ones) for the Fourier--Hermite coefficients. The exact results obtained are specified, and a number of comments regarding them are given.
On the influence of integral perturbations to the asymptotic stability of solutions of a second-order linear differential equation
Authors: Iskandarov Samandar , Abdiraiimova Nazigai
Published: August 2020

Sufficient conditions for the asymptotic stability of the solutions of a second-order linear integro-differential equation of the Volterra type are established in the case where the solutions of the corresponding second-order linear differential equation may have no property under study. Thus, the influence of integral perturbations on the asymptotic stability of solutions of linear differential equations of the second order is revealed. For this purpose, the method of auxiliary kernels is developed. An illustrative example is given.

Authors: Krykun Ivan
Published: August 2020

Some estimates of the parameters of a nonlinear regression between the variables of X and Y are constructed for the arctangent as a regression function. The obtained estimates are used to evaluate the unknown parameters of the Cauchy distribution. Computer simulations are performed, and the estimates are compared with another estimates such as the quantile ones, maximum liklyhood estimates, and some others. The confidence intervals for parameters of the Cauchy distribution are obtained.
Sobolev mappings and moduli inequalities on Carnot groups
Authors: Sevost'yanov Evgenii , Ukhlov Alexander
Published: August 2020

We study the mappings that satisfy moduli inequalities on Carnot groups. We prove that the homeomorphisms satisfying the moduli inequalities ($Q$-homeomor\-phisms) with a locally integrable function $Q$ are Sobolev mappings. On this base in the frameworks of the weak inverse mapping theorem, we prove that, on the Carnot groups $\mathbb G,$ the mappings inverse to Sobolev homeomorphisms of finite distortion of the class $W^1_{\nu,\loc}(\Omega;\Omega')$ belong to the Sobolev class $W^1_{1,\loc}(\Omega';\Omega)$.

Behavior of blow-up solutions for quasilinear parabolic equations
Authors: Yevgenieva Yevgeniia
Published: August 2020

We study the quasilinear parabolic equation $(|u|^{q-1}u)_t-\Delta_p\,u=0$ in a multidimensional domain $(0,T)\times\Omega$ under the condition $u(t,x)=f(t,x)$ on $(0,T)\times\partial\Omega$, where the boundary function $f$ blows-up at a finite time $T$, i.e., $f(t,x)\rightarrow\infty$ as $t\rightarrow T$. For $p\geqslant q>0$ and the boundary function $f$ with power-like behavior, the upper bounds of weak solutions of the problem are obtained. The behavior of solutions at the transition from the case where $p>q$ to $p=q$ is investigated. A general approach within the method of energy estimates to such problems is described.
From Theater to Cinematography: Creative Search of Les Kurbas
Authors: Demeshchenko Violeta
Published: August 2020

The article examines the artistic path and creative pursuits of Les Kurbas, the Ukrainian and soviet director, who undoubtedly remains an outstanding figure in the history of Ukrainian cultural life in the 1920s and 1930s. He was the founder of Ukrainian political theater, and later philosophical theater; also fruitfully worked in early cinematography.
The article emphasizes the relevance of studying the creative work of the director, his original creative method of educating actors nowadays. In his own way, Kurbas became a standalone theatrical institute for young people, raised more than four dozen professional directors who later became theater managers and directors of Ukrainian theaters, teachers. The director created Ukrainian theater and cinema school of acting; his innovative artistic ideas still remain relevant today. He developed his own aesthetic-theatrical concept of conditional-metaphorical theater based on life itself. Being the man of art, Kurbas influenced the formation of stage constructivism in Ukrainian theatrical art.
In addition to the positive memories of his contemporaries, we also encounter some legends, various testimonies and assessments of events of that time, which create a certain mythological space around the artist. Hence, today we need to carefully analyze numerous documentary evidence, facts, memoirs, literary and theatrical sources, as well as try to be objective in reconstructing events and reflecting on the fate and work of the director.
Cultural and Art Magazines in Western Ukraine from the Underground to Alternative Press
Authors: Babii Nadiia
Published: August 2020

The article analyzes the phenomenon of alternative cultural and art magazines of Western Ukraine of the 80-90s of the XX century; based on the analysis of factual data, interviews with stakeholders, scientific discussions, it clarifies the role of the object in the interdisciplinary connections of the XXI-century cultural discourse. The research determined that western cultural and art magazines of the late twentieth century played an important role for countercultural communities that were formed outside the official creative unions and also became a part of the common cultural myth under the same name. The closeness of the Chest union’s community to the aesthetics of the avant-garde was seen as opposition to the political regime, although they deliberately distanced themselves from politicization in their work as well as literary associations of the 1980s. The Сhetver (Thursday) magazine marked a new era of domestic journalism at the beginning of the 1990s, identified aesthetic criteria for alternative youth literature for a long period. The magazine became a symbol not only of a narrow get-together circle but also of an important part of the Stanislavsky phenomenon myth, in which all visual and verbal arts were a unified whole, thus blurring internal boundaries.
Antinomic Comprehension of God in Unity of Transcendent and Immanent Principles in the Leading Religious-Philosophical Systems and Art of the Second Half of the І Millennium ВС — the Beginning of a New Era
Authors: Bondarchuk Yaroslava
Published: August 2020

The article aims to trace the antinomic comprehension of God in unity of spiritual transcendent and material immanent principles in the major religious systems of the second half of the 1st millennium BC — the beginning of a new era and the reflection of this process in the art of that time based on analyzing religious texts, theological and philosophical treatises of the main monotheistic and polytheistic religious worldview ideas and ways of their embodiment.
The study showed that the universal idea of religious systems (Taoism, Confucianism, Hinduism, Buddhism, Christianity) of the indicated period is the idea of embodying the highest spiritual Absolut into a natural anthropomorphic form. In most leading religions of the time (except for Judaism) this interpretation of God became the basis for the development of religious art.
For the first time, a comparison of concepts of God in the leading religious-philosophical systems of the researched period was made. Such an interpretation of the deity has been shown to be manifested in religious art, which confirms its worldview subordination. It was hypothesized that the antinomic comprehension of God in the unity of transcendent and immanent principles in the leading religious systems formed at the turn of the millennia determined that the dominant zodiacal Pisces constellation, in which the Sun was rising on the day of the spring equinox, was characterized as a sign of the unity of antinomies.
This article may be used for further research, for the courses of lectures in the history of world culture.
Commodification as the Means of Cultural Production
Authors: Oliinyk Oleksandra
Published: August 2020

The paper discloses the phenomenon of the commodification of cultural production in course of evolutionary transformation of technic, technologic and economic capacities of society. Economic issues, including the definition of cultural product as a commodity, form the apparatus for the objectification of creative intention that does not impact directly on the creativity as freedom. Albeit the tension of social apprehension, spoken in words by either intellectual critics or market demand, and dependence on the market laws, reflecting either the labor issues or distribution and consumption, evoke the shift in the function of art, in particular, the loss of critical and regulative functions. Thus, the article seeks the logic dependence of the functional shifts in art on the phenomenon of commodification. The paper aims to justify the hypothesis that the commodification is an auxiliary tool for communication between the artist and audience, barely directly causing the leveling of aesthetic artistic value. Considering that the comprehension of commodification relies mostly on the philosophic criticism leaving the economic research of cultural production aside and missing the discourse of aesthetic and artistic essence, this paper concludes that the commodification of symbolic production, as the consequence of social and economic development, rather implies communicative capacity for artistic value than the destructive or leveling impact factor causing the shift of social functions of art.
Features and Functions of the Public Holiday
Authors: Haievska Tetiana
Published: August 2020

This paper defines the need to study public holidays not only as elements of tradition and cultural memory, but also as one of the most effective tools of public policy. Thereby, it is important to analyze the features of discourses, symbols, narratives, rituals and other elements of public holidays that are used in the political struggle for power and its retention.
There are not many publications researching specifically the subject of this study. However, there are a number of works highlighting certain aspects of the problem posed. This allows relying on already accumulated experience when studying the practical aspects of using holidays in the context of modern realities.
A traditional text analysis being the main method in the study, allows to assess the cultural, historical and political context, to show the basic rituals, ceremonies, narratives, meanings and symbols circulating in public space. The study also uses the comparative method, which allows to study the similarities and differences in interpretations and forms of celebration in other countries.
Thus, holidays in public policy are determined by functions which include legitimizing of the political regime, forming and maintaining national identity, educating and socializing, communicating, and planning for the future of the country.
The study defines the functions of state holidays emerging as an instrument of politics, ideas and meanings of public holidays, which can compete with official ones.
Genealogy of Stories: Constraction of the Subject by Vanishing Images
Authors: Ternovska Mariia
Published: August 2020

The article offers an essay on the genealogy of stories’ phenomenon from the self-eliminating pictures of private correspondence on Snapchat to “classic” public stories on Facebook and Instagram. Social media are usually associated with a space driven by the logic of the like economy or with the environment that nurtures a user to be a narcissistic subject. The survey proves stories to be an alternative mode of being online along with the way of depreciation of likes and other attributes of public recognition in the web (including comments and shares). In addition, the investigation points to the link between sensor technologies’ proliferation and a corresponding information structuring as a flow and stories’ emergence.
The separate part of the article is devoted to analyzing the mechanisms of the stories’ subject structuring. Applying Lacanian distinction between Symbolic, Imaginary, and Real, the author demonstrates how stories force a user to identify with a lost object and, consequently, how mechanisms of stories automatically reproduce a structure of a depressive disorder.

Conventional Resources and Postmodern Transformations of the Cultural Practices of Communication and Etiquette
Authors: Sudakova Valentyna
Published: August 2020

The article researches the integrative potential of the cultural practices of conventions under conditions of the global social transformations. It has analyzed the concepts of practice, cultural practice, convention, and essential characteristics of the role of conventions in organizing and supporting cultural and social orders. This study identifies the genetic sources of the sustainable general interactions and the real opportunities of the cultural practices of communication in order to define the conventional resource of the etiquette complexes. It investigates the etiquette and its peculiarities as the transcultural phenomena and describes its basic functions which determine the social significance of the etiquette in the space of cultural communications. The author emphasizes the importance of researching the historical connections of the contemporary etiquette models with the traditional norms of human behavior, such as taboo, rituals, customs which stipulate the controversial cultural and social consequences under conditions of cultural globalization, large-scale influence of information revolution, and the spread of network communications.
Europe as an Object of Desire: Ukraine between “Psychological Europe” and the “Soviet Mentality”
Authors: Korablyova Valeria
Published: August 2020

The article explores the idea of Europe in the Ukrainian national imaginary and its correlates in behavioral modes of modern Ukrainians. The conceptual tension exists between the imaginary “Us” (an affirmative “Ukraine is Europe”) and the real “Us” rooted in Soviet practices and mental attitudes. The main actors articulating the concept of Europe are distinguished: political elites/“officials”; cultural elites/“intellectuals”; civil society/“activists”; lay citizens/“electorate”. It is proved that for most Ukrainians Europe is not a value-in-itself; it is an empty signifier with variable content defined by divergent agendas. For Ukrainian politicians, declarative European integration is a geopolitical tool aimed at obtaining prestige/recognition and a protective umbrella of the EU, with no internal reforms by the European model. For cultural elites, “Europe” stands as a “civilizational standard” setting a framework for the search for national authenticity. Immanent Europeanness of the Ukrainian culture is proclaimed in the “frontstage” discourse, while in the “backstage” discourse, the lack of (self)recognition manifests itself through the symptom of being “more European than Europe”. Attempts “to acquire ourselves via Europe” are complemented with the desire “to rescue Europe via acquiring ourselves”. For citizens, “Europe” is a path to prosperity (“to build Europe at home”); yet, the content remains vague. A political struggle unfolds between the stakeholders of the captured state and public activists for the cornerstone ideas and principles, as well as for the trust of lay citizens as a political resource.
Structure of the Modern Culturology: Semiotic Triad
Authors: Bilchenko Yevheniia , Kalyta Tetyana
Published: August 2020

The article offers the semiotic analysis of culturology as an episystem. Culturology is regarded not as a “pure” academic discipline, but as an integrative project that combines elements of academic knowledge with ideologies. The paper aims to substantiate the internal structure of the culturology based on the combination of social and philosophical traditions. Representatives of cultural elites who embody a social science or worldview approaches are, in one way or another, influenced by the ideologies of the modernity (traditionalism, Marxism) and the postmodernity (neoliberalism). The scientific value of the study is that it proposes a semiotic model of culturology based on structuralism — a triadic structure consisting of theoretical, applied and practical cultural studies according to the three elements of the symbolic order (archetypes, meanings, forms). An attempt was made to conceptualize the cultural method, in which the structural analysis of cultural forms occurs as a movement from diachrony to synchrony, from the dynamic to the static principle of designation. This method is intended to bridge the gaps in the professional identity of cultural theory experts facing difficulties in critical ways of responding to the challenges of the world and cultural practitioners who are at risk of being transformed into carriers of the political economy’s service function.
Beethoven — the Zeus of Modernity
Authors: Loos Helmut
Published: August 2020

A large part of German musicology sees itself as a science of art in the emphatic sense and is committed to quite different principles than historical-critical approaches in the discipline. The latter seek to gain a realistic picture of the history of music, including contemporary ways of thinking, and allow for historical actors to make meaningful, free will decisions within anthropologically determined circumstances. The emphatic science of art, on the other hand, claims to be able to prove and scientifically determine the objects of great art music and their nature. It originated during the Enlightenment, when philosophy took the place of religion and created ever new theoretical constructs of thought presented as scientifically proven and binding. In music, Beethoven rose to the ideal of the ingenious creator, who embodied the progress and achievements of mankind on the path toward perfection. Thus, in the course of the 19th century, a Beethoven cult developed using philosophy as its guide in selecting and evaluating historical sources, gladly accepting literary testimonies as historical fact. Historical criticism, which revealed this construction of a romantic image of Beethoven, was suppressed for a long time. Society’s broad acceptance of the notion of the evolutionary progress of mankind, one to which modernity adhered, proved too powerful, and belief in it took the form of an art religion. Beethoven as Zeus of the Third Reich, as the god of modernity, was the program and message of the 14th Secession Exhibition in Vienna in 1902. This image was destructed in the late 20th century.
Methodological Approach to the Analysis of the Accordion Art of Serbia
Authors: Nisic Katarina
Published: August 2020

Modern society is increasingly acquiring features of a ‘knowledge society’ as it develops based on the processes of production, distribution and use of scientific knowledge that allow to construct a new social reality, its economic and mental structures, a new way of life. This context makes relevant the issues of changing the socio-cultural status, functions and new tasks of the Institute of Higher Education as one of the main producers and disseminators of scientific knowledge. Much attention at the present stage of development of higher education is paid to the problem of transferring it to a musical innovative basis, i.e. considering such musical innovative elements in the training that would ensure an appropriate level of competitiveness of domestic education in the globalization of art. The article aims to substantiate and develop the methodological approach to the analysis of accordion art of Serbia in the context of the introduction of musical innovations. The research develops and substantiates a methodological approach to the analysis of accordion art, the main essential features of which are the assessment of each individual art component of experimental training, generalization of results and implementation of measures to improve the quality of professional communicative competence. It specifies indicators based on sustainable art components. To determine the intervals for assessing the quality of performance of future music teachers in the process of teaching accordion, the author proposes a corresponding scale.
Goddess-Cosmos of Proto-Myth in Ornaments of Folk Embroidery of Bukovina (the Case of the E. Kolbenhier’s Collection)
Authors: Prychepii Yevhen
Published: August 2020

The study analyses the semantics of ornaments of Bukovinian embroideries samples collected by E. Kolbenhier during the period from 1902 to 1912. Resulting from the concept of the proto-myth offered by the author, it is proved that the ornamental symbols hid images of the archaic goddess identical with the Cosmos. The study shows that the ornamental image of a flower is constructed from “female” symbols (in particular, rhombuses) arranged according to structures 1+1+1 or 1+2+1 which model the goddess. It is shown that the image of the goddess (one, two or three goddesses) is as well hidden behind ornamental structures of a tree. The article analyses ornaments that model volumetric Space as the structure formed from concentric rectangles symbolizing a dungeon, the terrestrial world and heavens. It is shown that this structure models an ornament placed on the Stone-Age pots. Studying the semantics of the S-symbol, it is argued that it can denote summer or winter half-cycles of the Sun, which the goddess embodied in archaic symbolism. Accordingly, it was concluded that the ornamental “endlessness” consisting of S-symbols and simulating the cycles of the sun transmits temporary infinity.

Reflexiones sobre Filosofía y la Realidad Científica
Authors: Hernández-Bowen Luis Alberto
Published: August 2020

En el presente ensayo he querido expresar mis ideas sobre la filosofía y a realidad científica, por cuanto en mis vivencias dentro de los entornos académicos universitarios doctorales he podido percibir las tendencias evidenciadas dentro de la producción científica, tales como tendencias orientadas por el mundo post-estructuralista como el relativismo, la tendencia de lo fenomenológico hermenéutico. Todo ello, evidencia una corriente anticientifista basada en el manifiesto de la misma índole de Dilthey. En buena medida esto se debe a la necesidad de reflexionar sobre la filosofía que en mi perspectiva es la gran validadora de la ciencia, pese a existir una tendencia basada en la epistemología naturalizada que propone desvincular la ciencia de la filosofía. Es necesario que dentro de los entornos universitarios doctorales, retomar las reflexiones sobre la filosofía que fundamente nuestro proceso para la innovación del conocimiento, pero con sustentación y desde estándares aceptables que brinda una alta contratación teórica como tarea inelusible, desde donde extiendo la invitación a este compartir de conocimientos.
Shen's -process on Berwald connection
Authors: Faghfouri M. , Jazer N.
Published: August 2020

The Shen connection cannot be obtained by using Matsumoto's processes from the other well-known connections.  Hence Tayebi–Najafi introduced two new processes called Shen's and -processes and showed that the Shen connection is obtained from the Chern connection by Shen's -process.  In this paper, we  study the Shen's - and -process on Berwald connection and introduce two new torsion-free connections in Finsler geometry.  Then, we obtain all of Riemannian and non-Riemannian curvatures of these connections.  Using it, we find the explicit form of -curvatures of these connections and prove that -curvatures of these connections are vanishing if and only if the Finsler structures reduce to Berwaldian or Riemannian structures.  As an application, we consider compact Finsler manifolds and obtain ODEs.
