Creep mechanical tests and shear rheological model of the anchorage rock mass under water‒rock coupling
Authors: Zhongliang Zhao , Wukui Dai , Jianjun Yang , Mi Zhou , Ziwei Liu
Published: April 2023

The development of deep geotechnical engineering is restricted by the complex geological conditions of deep rock masses and the unknown creep mechanism of rock in water-rich environments. To study the shear creep deformation law of the anchoring rock mass under different water content conditions, marble was used as the bedrock to make anchoring specimens, and shear creep tests of the anchoring rock mass under different water contents were carried out. The influence of water content on rock rheological characteristics is explored by analysing the related mechanical properties of the anchorage rock mass. The coupling model of the anchorage rock mass can be obtained by connecting the nonlinear rheological element and the coupling model of the anchorage rock mass in series. Related studies show that (1) shear creep curves of anchorage rock masses under different water contents have typical creep characteristics, including decay, stability and acceleration stages. The creep deformation of the specimens can be improved with increasing moisture content. (2) The long-term strength of the anchorage rock mass shows an opposite change law with increasing water content. The creep rate of the curve increases gradually with increasing water content. The creep rate curve shows a U-shaped change under high stress. (3) The nonlinear rheological element can explain the creep deformation law of rock in the acceleration stage. By connecting the nonlinear rheological element with the coupled model of anchoring rock mass in series, the coupled model of water‒rock under water cut conditions can be obtained. The model can be used to study and analyse the whole process of shear creep of an anchored rock mass under different water contents. This study can provide theoretical support for the stability analysis of anchor support tunnel engineering under water cut conditions.

The presence of human cytomegalovirus (HCMV) in glioblastoma (GBM) and improved outcomes of GBM patients receiving therapies targeting the virus have implicated HCMV in GBM progression. However, a unifying mechanism that accounts for the contribution of HCMV to the malignant phenotype of GBM remains incompletely defined. Here we have identified SOX2, a marker of glioma stem cells (GSCs), as a key determinant of HCMV gene expression in gliomas. Our studies demonstrated that SOX2 downregulated promyelocytic leukemia (PML) and Sp100 and consequently facilitated viral gene expression by decreasing the amount of PML nuclear bodies in HCMV-infected glioma cells. Conversely, the expression of PML antagonized the effects of SOX2 on HCMV gene expression. Furthermore, this regulation of SOX2 on HCMV infection was demonstrated in a neurosphere assay of GSCs and in a murine xenograft model utilizing xenografts from patient-derived glioma tissue. In both cases, SOX2 overexpression facilitated the growth of neurospheres and xenografts implanted in immunodeficient mice. Lastly, the expression of SOX2 and HCMV immediate early 1 (IE1) protein could be correlated in tissues from glioma patients, and interestingly, elevated levels of SOX2 and IE1 were predictive of a worse clinical outcome. These studies argue that HCMV gene expression in gliomas is regulated by SOX2 through its regulation of PML expression and that targeting molecules in this SOX2-PML pathway could identify therapies for glioma treatment.
A Corpus-Based Investigation of Intensifier Use by L2 Learners of Korean
Authors:   The Society Of Modern Grammar, Hwang Sun Hee
Published: April 2023

This study aims to investigate the use of Korean intensifiers by L2 learners based on data from a learner corpus. This study focuses on five intensifiers: maywu, cincca, nemwu, toykey, and acwu, which are found to be frequent intensifiers in Korean native speakers’ data. Based on native speakers’ data, it is known that toykey and cincca among those intensifiers are generally used in spoken language while, in general, maywu is rarely used in spoken language. Comparing the Korean Learner Corpus by the National Institute of Korean Language with the Sejong Corpus, this study examines whether L2 learners change intensifiers according to the modes of production (i.e., spoken and written language) and their proficiency levels. Unlike native speakers’ data from the Sejong Corpus, L2 learners overall tend to use far more intensifiers in writing than in speaking. Compared with higher-proficiency learners, lower-proficiency learners, in general, tend to overuse intensifiers. In using toykey and maywu, it is also found that their differences in speaking and in writing get lager as proficiency level becomes higher. These findings indicate that higher-proficiency learners perform in a more target-like way in using an intensifier, and thus suggest that the pattern of native speakers in intensifier use is acquirable.

Published: April 2023

This study aims to investigate various usages and those semantic associations of ‘kada’ in Daegu Dialect. Though a number of previous researches already dealt with different functions of ‘kada’, such as quotation verb, utterance verb, and pro-verb, this study tries to analyze in detail individual grammatical characteristics and explore comprehensively their mutual relation. In addition, by discussing together ‘ikada, geukada, jeokada’, which had been developed in the opposite direction with ‘kada’, it is confirmed that these words have a close and systematic correspondence with each other in terms of grammar.

Authors: Dovbnia D. V. , Kaplaushenko A. H.
Published: April 2023

In today’s society, the work of a pharmaceutical worker is very respectful, because it is difficult to imagine the treatment of people without the use of drugs. As time passes, the number of diseases with their own characteristics only increases, so the creation of drugs of synthetic origin remains an actual task for scientists around the world. There are a large number of heterocyclic systems, the derivatives of which exhibit a wide range of pharmacological activities, namely, furan, pyrrole, pyrazole, pyridine, pyrimidine, purine, and many others. Particular attention is drawn to structures that have low toxicity. Undoubtedly, the initial heterocyclic substance must have several reactive centers in order to build the most effective pharmacophores.
Studies by scientists from around the world point to the prospect of using derivatives of the 1,2,4-triazole heterocyclic system as models for new biologically active substances.
The aim of the work was to summarize data on modern methods for the synthesis of 1,2,4-triazole derivatives, to determine the effect of a methoxyphenyl substituent on reactivity and changing the spectrum of pharmacological activity.
Materials and methods. In the work, we used such methods as analytical, information search, descriptive, generalization. The materials of the research were information from the professional literature on the methods of synthesis and study of the biological activity of 1,2,4-triazole derivatives with methoxyphenyl.
Results. A search, analysis, and generalization of information on the methods of synthesis and study of the biological activity of 1,2,4-triazole derivatives with methoxyphenyl were carried out. As a result of the studying available sources and implementation of scientific research, it was found that studies of 1,2,4-triazole derivatives with methoxyphenyl occupy an important place in the Ukrainian pharmaceutical industry, as they have a wide range of pharmacological activity. Also they show low rates of acute toxicity and are perspective to create new APIs on their base
Conclusions. Processing, analysis, systematization, comparison, and generalization of modern sources of information indicate a wide synthetic variability, a fairly wide range of biological activity, and low rates of acute toxicity of 1,2,4-triazole derivatives, with methoxyphenyl at the 5th position of the nucleus of this heterocycle and a wide range of their applications.
Analysis of the activity of c-kit immunopositive alpha-cells of the pancreas in exogenous infusions and endogenously formed pathology
Authors: Ivanenko T. V.
Published: April 2023

There are a number of factors and agents that change the population of endocrinocytes and their secretory activity depending on various conditions and experimentally formed pathologies. These include the impact of intermittent hypoxic hypoxia; experimentally formed pathology (diabetes); genetically formed pathology (arterial hypertension), direct effect on endocrinocytes of the pancreas with their own pathophysiological mechanism. In this context, it is interesting to analyze the state of the progenitor potential of alpha cells depending on the living conditions of the organism, its effects, and developing pathological conditions in it.
The aim of the work is to determine the activity of the proliferative factor c-kit in alpha cells under exogenous factors – intermittent hypoxic hypoxia and endogenously formed pathology – arterial hypertension and diabetes.
Materials and methods. The study was conducted on the pancreas of SHR and Wistar rats. Glucagon and c-kit in pancreatic islets were determined by the immunofluorescence method. The immunofluorescence reaction was studied with an AxioImager-M2 fluorescence microscope.
Results. Analysis of the c-kit positive alpha-cell index in rats with diabetes showed a 5-fold increase. This was explained by the fact, that the development of hyperglycemia in diabetes mellitus was characterized not only by an increased level of glucose in the blood due to insufficient insulin production but also due to an increase in the number of alpha cells, their active proliferation and possible transdifferentiation from beta cells. The number of c-kit positive alpha cells in SHR rats decreased. This may indicate that these changes were not so related to a violation of the modulation of the transcription factor, but to the participation of neurogenic mechanisms. The decrease in c-kit positive alpha cells in animals with hypoxic hypoxia can be explained by transdifferentiation (remodeling) changes, aimed at suppressing proliferative processes in alpha endocrinocytes.
Conclusions. The increase in the number of c-kit positive alpha cells in rats with diabetes is explained by the fact, that the development of hyperglycemia in diabetes is characterized not only by an increased level of glucose in the blood due to insufficient insulin production but also by an increase in the number of alpha cells, their active proliferation and possible transdifferentiation from beta cells. A decrease in the number of c-kit positive alpha cells in SHR rats may indicate that these changes are not so much related to a violation of the modulation of the transcription factor, but to the participation of neurogenic mechanisms. The decrease in c-kit positive alpha cells in animals with hypoxic hypoxia can be explained by transdifferentiation (remodeling) changes, aimed at suppressing proliferative processes in alpha endocrinocytes.

Ateizm, metafizyka i filozofia demokracji. Refleksje o teologii Braci Polskich
Authors: Paradowski Ryszard , Paradowska Wiera
Published: April 2023

Artykuł poświęcony jest argumentom na rzecz tezy, że istotnie ateistyczna jest nie tylko koncepcja, zgodnie z którą „Bóg nie istnieje” (Bóg w znaczeniu, jakie nadają mu teologie), ale również teoria, która, wstępnie deklarując przywiązanie do idei Boga religijnie rozumianego, zarazem formułuje swoje wyznanie wiary w porządek społeczno-kulturowy i aksjologiczny w sposób zasadniczo sprzeczny z wizerunkiem Boga jako najwyższego szczebla absolutnej hierarchii, jako uosobienia absolutnej siły i wyłącznej kompetencji do definiowania dobra i zła. Ateizmem w tym rozumieniu jest pogląd o zasadniczo niehierarchicznej budowie świata i o nieistnieniu jednego absolutnego autorytetu i  ateizmem w tym rozumieniu jest (pomimo teistycznej deklaracji) światopogląd Braci Polskich.
Reakcje wybranych podmiotów na zniszczenie gazociągów Nord Stream. Problem jakości informacji obecnej w przestrzeni publicznej
Authors: Wojcieszak Łukasz
Published: April 2023

Zniszczenie gazociągów Nord Stream we wrześniu 2022 roku spowodowało pojawienie się w światowych mediach bardzo zróżnicowanych opinii dotyczących sprawców tego ataku. Według autora, można postawić tezę, że w bardzo zróżnicowanym przekazie płynącym od wielu podmiotów bardzo trudno jest próbować wskazać sprawców tego czynu. Oprócz, co naturalne, sprzecznych ze sobą poglądów przedstawicieli poszczególnych zainteresowanych państw, w cyberprzestrzeni pojawia się bardzo wiele informacji mających nie tyle przekazać stanowisko określonych graczy, ile wprowadzić w błąd odbiorców. Zachodnie media najczęściej winą za atak obarczają Rosję, jednak przeciwnicy tego poglądu wskazują jego słabe strony. W pracy przedstawiono przykłady dezinformacji zawartych w przekazie medialnym w sprawie ataków na Nord Stream, w tym rolę fake newsów, niekiedy stosunkowo łatwych do wychwycenia, lecz niewątpliwie wpływających na kształtowanie się poglądów opinii publicznej. W artykule zastosowana została metoda czynnikowa, a także metoda prognostyczna.
Geospatial Methods and the Premodern Economy: Mapping the Institutional Landscapes of Northern Europe, 1350–1650
Authors: Holterman Bart , Huang Angela
Published: April 2023

The premodern European transport network was accompanied by a number of institutions that affected the transaction costs related to commercial travel, such as fairs, staple markets and toll stations. With digital techniques and big datasets, it is now possible to study these phenomena on a grand scale and to reveal patterns in supraregional economic exchange. Using the Viabundus dataset on premodern transport and mobility in northern Europe (13501650), this article explores the possibilities that such data offer for understanding large-scale economic activity. By employing GIS mapping for visualisation purposes and methods of network analysis such as the calculation of betweenness centrality, the data on fairs, staple markets and toll stations can help us understand the institutional structure of the premodern economy in which merchants operated.
Die Statistik der Betriebsrente
Authors: Mävers Dorothee , Pieper Jonas
Published: April 2023

This paper investigates the sources of information and their quality as accessible to the government of the Federal Republic of Germany when trying to assess the situation of company funded pensions between 1949 and 1985 for the Company Pension Act of 1974. By taking a closer look at multiple government surveys as well as official statistics, the paper shows that the government only had very little access to verifiable and detailed information on the matter and relied largely on estimates. There were no coherent sources of information, and none were set up after the Act came into effect. The trend of a growing distribution and extent of corporate retirement plans from the late 1940s to the 1980s as seen in the government surveys is congruent with our findings. Furthermore, the Company Pension Act strengthened this already growing trend.
Neoliberalismus: Über ein intellektuelles Missverständnis
Authors: Trecker Max
Published: April 2023

The term neoliberalism is a faithful companion of current public debates. It often serves as a proxy for what is allegedly wrong with society. The term is used to criticize a perceived commodification of spheres of human existence that used to be shielded from a purely economic logic. Recently, the term neoliberalism has become the object of historical research. Its roots have been traced back as far as 1947 or 1918. I argue in this paper that historians have taken a methodologically questionable approach, by departing from the blurry concept of neoliberalism as it is perceived today and trying to trace it back in time as far as possible. Such an approach leads to severe contradictions as economists labelled ex-post as neoliberals were often opposed to neoliberalism as it is currently defined. It is methodologically more sound and analytically more rewarding to start the conception of the term with the economists who self-identified as neoliberals. This approach leads to a more coherent concept of neoliberalism that is better suited for further research and provides a clearer understanding of the history of economic thought in the interwar period and the first postwar years.

Authors: Brás Eduardo J. S. , de Barros Fernandes Pedro Carlos
Published: April 2023

Miniaturization brings along significant advantages in the development, optimization, and implementation of chemical, biochemical, and related fields processes and assays. Given the reduced footprint, miniaturization allows a significant reduction in volumes to be processed while providing conditions for several conditions to be evaluated simultaneously. Accordingly, work can be performed timely in a space efficient manner, with significant costs savings. Microfluidics is the pinnacle of miniaturization, where the previous advantageous aspects are taken to the limit, with the added features of operation under well-defined and highly efficient mass and heat transfer environment. Additionally, microfluidic environment fosters process integration, monitoring, and control in a single framework. The present chapter aims to provide an overview of diverse applications of miniaturized devices, fabrication methods, and key issues in fluid dynamics that characterize a microfluidic environment.
Maximizing advantages and minimizing misinterpretation risks when using analogies in the presentation of chemistry concepts: a design challenge
Authors: Mammino Liliana
Published: April 2023

Analogies are frequently used in chemistry education (and science education in general), above all when introducing a new concept or when a concept is perceived as too abstract by the teacher or by the learners. On the one hand, analogies can offer functioning opportunities for clarifications; on the other hand, they may risk engendering misinterpretations or misconceptions, because the terms of a given analogy may be perceived differently by the teacher and by the student, or may be too farfetched to have a clarifying role. In order to maximize the benefits and minimize the risks, the design of analogies needs to entail careful attention both to the nature of the analogy and to its ‘matching’ to the nature of the concept to which it refers. This involves vigilant analysis of all the details and of their implications, and the parallel design of a viable way to guide the student through the terms of the analogy; such guidance is actually meant to become an explanation component. The paper considers concrete examples from the author’s direct experience with general chemistry and physical chemistry courses, and analyses both the design of the details of the selected analogies and the corresponding guidance pathways. It also discusses related issues like the importance of limiting the resort to analogies to the cases where they can actually have a significant impact on students’ understanding, and the opportunity of replacing them with molecular models whenever feasible, as a model’s nature is closer to the mental images that it is desirable to promote through students’ perceptions. Comparisons of the types of guidance needed for analogies, for general-type visualization, and for visualization through models are also included. The take-home message reiterates the considerations on the nature of analogies as something to be designed, on the teacher’s active role in the design, and on the possibility of including students in the design process, when the concepts and corresponding analogies are suitable for such inclusion.

Published: April 2023

The ternary Laves phases Sr2Pd3Sn, Eu2Pd3Sn and Eu2Pd3In were synthesized by induction melting of the elements in sealed tantalum ampoules. The polycrystalline products were characterized through their powder X-ray diffraction patterns. The structure of Eu2Pd3Sn was refined from single crystal X-ray diffractometer data: Mg2MnGa3 type, Cmcm, a = 583.36(5), b = 908.31(7), c = 958.06(8) pm, wR2 = 0.0366, 557 F
2 values, 23 variables. The palladium and tin atoms show the inverse coloring on the network of condensed tetrahedra of Mg2MnGa3, i.e., MnGa3 versus Pd3Sn. Refinement of the occupancy parameters revealed small defects for the europium site, leading to composition Eu1.962(6)Pd3Sn for the studied crystal. Sr2Pd3Sn is a Pauli paramagnet and Eu2Pd3Sn shows Curie-Weiss paramagnetism (7.86(1) µB Eu atom−1 and Θ
P = 48.1(1) K). Ferromagnetic ordering is observed below T
C = 46.1(1) K. The 119Sn and 151Eu Mössbauer spectra of Sr2Pd3Sn and Eu2Pd3Sn are discussed with respect to electron density changes as a function of the tin content and the ionicity in the sequence of the stannides Sr2Pd3Sn/Eu2Pd3Sn → Sr2Pd2Sn/Eu2Pd2Sn → EuPdSn → EuPdSn2.
Understanding formation of the InPd3polymorphs: a DFT study
Authors: Roy Nilanjan
Published: April 2023

The intriguing experimental results regarding the synthesis and structure types adopted by binary InPd3have been fundamentally addressed using first-principles density functional theory calculations. Longer annealing time at higher temperature leads to stronger and more optimized heteroatomic In–Pd contacts that result in the extended ordering between them and leading to the ZrAl3structure type. This is followed by another ordered derivative of the TiAl3-type and the metastable disordered AuCu-type when the annealing time and temperature were reduced. The thermodynamic stability order of these three polymorphs of InPd3, i.e. ZrAl3-type > TiAl3-type > AuCu-type is understood from the correlation between formation enthalpies, Madelung energies, and electronic structure and chemical bonding analysis.
Enhancement of Indonesian High School Student Conceptual Mastery on VSEPR Topic Using Virtual Simulation of Molecule Shapes: A Case Study of Quasi-Experimental Evidence
Authors: Stiawan E. , Basuki R. , Liliasari L. , Rohman I.
Published: April 2023

The Valence Shell Electron Pair Repulsion (VSEPR) is an essential topic for high school student’s fundamental understanding of 3D shapes of chemical compounds. Due to the spatial aspect of the topic, the students were forced to imagine the geometry of the molecule by predicting the free or bonded electron pair repulsion. Suitable learning media to accommodate those features should be precisely selected to help students properly understand the geometry of the molecule based on the VSEPR topic. This study compared the significant difference in the application of two media of animation video and interactive simulation toward the control and experimental groups, respectively, to enhance conceptual mastery of the VSEPR topic. This study was a statistical quasi-experiment study with two classes of control (animation video) and experimental (interactive simulation) groups. The results of the significant difference test of the groups showed that the distribution of the experimental and control groups was not normal (significantly different) and normal (not significantly different), respectively. Analysis results using Mann-Whitney for the non-parametric free two samples comparative test with a 95% confidence level showed that the application of virtual simulation on the experimental group impacted more in improving the conceptual mastery of the VSEPR topic. Furthermore, there was an identified significant improvement in sub-concepts of the VSEPR topic in binding pair, molecular shape, and electron repulsion. These findings could support the teachers in designing lesson plans for students to master the VSEPR topic.

Published: April 2023

The COVID-19 pandemic has affected education in Indonesia. The government has suggested alternatives to solve the learning problems during the pandemic. Offline and online classes were used to fulfil the various learning needs of students. This study investigated the effect of using augmented reality-assisted media in offline and online classes on student achievement amid the COVID-19 pandemic. This study used a quasi-experimental design by utilising augmented reality (AR) in each class for eight weeks. Validated test questions were used following the use of AR. According to the results of the independent t-test in the current study, student achievement from offline (n = 63, M = 74.71) and online (n = 64, M= 71.46) classes increased drastically with t = 1.994, p = 0.048. However, in terms of differences in achievement improvement between the two classes, students in offline classes had higher achievement compared to those in online classes. Thus, it can be concluded that student achievement in Physics has improved with the help of augmented reality-assisted media amidst the COVID-19 pandemic, particularly through offline learning mode. This study contributes to the development of AR for future education, particularly how to enhance student achievement in Physics. Future AR studies can be carried out in more classes from various regions or countries, considering that the 3D models in AR are useful to aid the learning of other subjects with abstract concepts.
Sustainability Assessment of Integrated Waste-to-Use Systems: A Case of Uganda
Authors: Agunyo Miria Frances
Published: April 2023

For countries like Uganda where organic waste composition accounts for at least 70% of the solid waste generated, collected, and disposed of at landfills and dumpsites, recovery of resources from the waste stream is crucial. This is because disposal of the waste in the landfills/dump sites exerts more pressure on land as a resource in addition to the environmental negative impacts associated with the degradation of the waste in the landfills, pollution of groundwater from leachate, generation of greenhouses gases, bad odor, and poor aesthetics. Moreover, given that the country also grapples with sewage and faecal sludge treatment and management due to the limited plants in place, alternative Waste-to-Use systems that promote resource recovery and management of various organic waste streams such as biowaste, animal manure, sewage/faecal sludge and wastewater could be a viable solution. The systems which consist of a combination of various technologies such as anaerobic digestion, incineration, landfilling, composting, and pyrolysis to produce briquettes boast of managing various organic waste streams and potential for application in various entities such as housing estates, towns/cities, at institutions. To assess the sustainability of such systems, multicriteria decision analysis was used. The results indicated that if trade-off of any aspect was considered i.e., technical, environmental, social, and financial, the Waste-to-Use systems were preferred i.e., a system consisting of composting and anaerobic digestion technologies. Also, a sustainability framework for the assessment of similar systems was proposed and it highlights the importance of involving stakeholders through the various stages such as, situation analysis, problem identification and definition, criteria and indictor selection, elicitation of scores and weight so that transparency in decision making can be boosted.

Introduction. The events of the October Revolution of 1917 completely changed all aspects of public life. This change occurred, among other things, due to large-scale public education. The purpose of enlightenment was the formation and popularization among the citizens of the country of a new proletarian culture based on Marxist-Leninist ideology. The spread of club institutions helped to achieve this goal. The purpose of the article is to analyze the activities of club institutions in the Tatar locality of Mordovia during the Soviet period. The article contains statistics on the number of club institutions and their variety, talks about the difficulties that club institutions faced, and so on.

Materials and Methods. The research is based on documents from the Central State Archive of the Republic of Mordovia. Previously published studies that talk about Soviet educational policy have also become an important source. The methodological body of the study includes comparative-historical, chronological and statistical methods.

Results. During the study, statistics were prepared on the number and types of club institutions in the Tatar locality of Mordovia, and some of their features have been identified. Problems faced by club establishments have been identified. The main problems were material difficulties, the lack of proper attention to club institutions by local authorities, and the lack of qualified personnel.

Discussion and Conclusion. The study of this topic made it possible to establish that the Tatars living in Mordovia, together with the Russian and Mordovian people, became part of the general cultural and educational process that began after 1917. In the Tatar locality, various club institutions developed, which, in the case of good personnel work and a responsible attitude on the part of local authorities, became a real cultural center and carried out large-scale political and educational work. The article also provides examples of the unsatisfactory work of club institutions. For example, they did not function in every Tatar locality. Often, one club could unite several settlements, and this situation was observed throughout Mordovia.
The Impact of Advertising on Homo Glamorous Consumerism
Authors: Iakovlev Elena L.
Published: April 2023

Introduction. The relevance of the research topic is due to the ideology of glamour prevailing in modern society, due to which consumption becomes a lifestyle of a person acquiring Homo glamorous traits. His consumerist attitudes are stimulated by advertising. The purpose of the article is to analyze advertising strategies that cause Homo glamorous consumerist behavioral algorithms.

Materials and Methods. The ideas of R. Arnold, R. Barth, J. Baudrillard, B. Groys, G. Marcuse, N. Luhmann, A. V. Ulyanovsky served as material for theoretical understanding of the problem. Analytical and included observation were chosen as the research methods.

Results. It is revealed that advertising, based on the technology of myth design, includes a specially constructed sexually seductive image and a mythized text in which projectivity for change acts as a striking force. The technology of myth design in advertising contains an explicit or veiled call to consumption, emphasizing that the product, service, fashion attribute are made for you and you deserve it. Homo glamorous consumerist tactics can be classified as non-functional consumption. Among its types we include consumption based on impressions from glamorous images, symbolic consumption and consumption for show or demonstrative consumption.

Discussion and Conclusion. The analysis of the problem reveals the domineering nature of advertising, but it has a soft form of advice. Following advertising instructions demonstrates not only Homo glamorous dependence on them, but also reveals hidden and often unconscious personality traits. They are connected with the dream of the best, formed today by advertising and its projectivity for change. This fact indicates the romanticism of the nature of Homo glamorous. But glamorous romanticism is a transformed version of romanticism, where the emphasis shifts towards the personality itself and its way of life, the manifestation of a duality in the form of an internal split into Me and I-for-show-for-Another, demonstrating the illusion of creativity and freedom of choice. As a result, homo glamorous turns out to be not self-sufficient and confused in being.

Published: April 2023

Introduction. The fact that the representation of COVID-19 in folklore is a reflection, fixation, translation, and illocution of the ethnic semantics of the pandemic determined the relevance of my investigation. Studying COVID-related folklore allows us to understand the current norms and values prevailing in the Russian superethnos, the attitude of various socio-demographic groups to the changes taking place in society, realities, and events correlating with the pandemic, and violations of the generally accepted normative value system revealed by the changed living conditions. No one has carried out such studies yet. My work aims to investigate the semantics of the COVID-19 pandemic in folklore; namely, to determine the social content and grounds, assessments, and self-assessments of social groups in the Russian semantic picture of the pandemic, as well as the functions performed by comic folklore concerning the pandemic.

Materials and Methods. I chose anecdotes as the material for the study because those are forms of folklore that clearly and succinctly reflect sociality and ethnic semantics. I applied the method of random sampling to select 1 000 Russian-language jokes distributed on the Internet in 2020–2021 and associated with the pandemic. I carried out my research within the framework of analytical philosophy using the comparative historical method, which allowed me to select relevant material, the method of quantitative and qualitative content analysis, which allowed me to systematize the data obtained, as well as general scientific methods of comparison, comparison, and classification, which provided interpretation of the results and formulation of conclusions.

Results. I revealed the content and the foundations of comic COVID-related folklore in socio-demographic, socio-political, socio-economic, socio-migration, and socio-cultural contexts. I determined social assessments of various phenomena, events, and behaviors associated with the pandemic.

Discussion and Conclusions. I defined epistemological, ontological, logical, logical-linguistic, and historical social functions of Russian pandemic-related folklore. I revealed the following reasons for the comic representation of the pandemic: pessimism and tension in society, the discontent of the inhabitants with the insufficient effectiveness of anti-pandemic measures and the lack of state support, the deterioration of the economic situation of citizens, as well as the degradation of people and relationships, culture and schools revealed during the pandemic, the growing absurdness of life in general.

Published: April 2023

Introduction. Modernization of society and tradition is manifested in the results of socio-cultural existence on a broader information base compared to the previous one. Such a base, in our opinion, is the entire world historical and philosophical process, in all its diversity and organic integrity of content. The purpose of the article is to examine the influence of the spiritual tradition of Byzantium on Russian philosophy, therefore, the problem of spirituality is one of the main ones in the heritage of Russian philosophers.

Materials and Methods. The spiritual life of a person was at the center of the interests of thinkers and is primarily reflected in religious and moral literature. The theoretical basis was the basic concepts of the philosophy of traditionalism − a socio-philosophical direction, which is based on practical wisdom expressed in tradition. Traditionalism acts as the leading methodology of religious studies and theological research. The methodological tools of the work are comparative-historical, hermeneutic and axiological methods that allow a multidimensional interpretation of the problem from a philosophical point of view.

Results. It is argued that Christian spirituality is characterized by traditionalism and in Byzantine Orthodoxy it was particularly consistent. In this regard, it is impossible to turn to the origins of the development of domestic spiritual and moral traditions without analyzing the factors of the successive influence of the Byzantine patristic tradition on the entire structure of the religious consciousness of Russians. When studying the factors of succession, the process of transferring spiritual heritage in the process to younger generations from previous generations is taken into account.

Discussion and Conclusion. Despite the difference of ideas and views, Russian philosophy contains the deepest understanding of the problems of spiritual existence concerning the citizens of Russia of the twentieth century. One of the features of the modern social situation is the increased interest of a in confessional issues. The basis for the development and strengthening of each great civilization is both local traditions and a continuous dialogue of civilizations, societies and cultures. The research materials can be used in the creation of civilized concepts of such a dialogue.
¿Quién causa tanta alegría? La Gritería: patrimonio cultural inmaterial dentro y fuera de las fronteras nicaragüenses

Published: April 2023

La festividad nicaragüense dedicada a la Purísima Concepción de la Virgen María es un tema muy vasto. En este estudio nos proponemos acercarnos a la Gritería, actividad celebrada en la víspera. Se pretende mostrar que el valor patrimonial de un bien cultural es un proceso que se construye por distintas vías, como creación, apropiación, resemantización y adaptación innovadora a las circunstancias compartidas por un colectivo y que lo estima como referente identitario. Este es el caso de la Gritería, ejemplo de cultura viva del pueblo nicaragüense, de cobertura nacional y que ha migrado fuera de sus fronteras. Se llevó a cabo trabajo etnográfico y se aplicaron técnicas cualitativas de investigación social en distintas comunidades de Nicaragua. Asimismo, se presentan algunas referencias a la celebración en países donde han emigrado personas nicaragüenses. Además, se señala la gestión participativa en la organización de tan importante festejo que mantiene la función de unir al pueblo nicaragüense y el encuentro de tradiciones. El resultado del estudio denota que, a pesar de las diferencias, la Gritería es un elemento de valor patrimonial, de significado para distintos sectores del pueblo nicaragüense, sea o no creyente, la Iglesia Católica y el Gobierno.
