Exendin-4 regulates the MAPK and WNT signaling pathways to alleviate the osteogenic inhibition of periodontal ligament stem cells in a high glucose environment
Authors: Wang Min , Liu Min , Zheng Jiawen , Xiong Li , Wang Ping
Published: April 2023

Diabetes mellitus (DM) increases the destruction of periodontal tissue and impairs osteogenesis differentiation. Exendin-4 (Ex-4), a glucagon-like peptide-1 (GLP-1) analogue, can be used for treating DM and promotes bone regeneration. The aim of this study was to explore the effect and mechanism of Ex-4 on improving the osteogenesis of periodontal ligament stem cells (PDLSCs) in a high glucose environment. Alkaline phosphatase staining and alizarin red staining were used to detect the osteogenic differentiation of PDLSCs. The results showed that 10 nM Ex-4 could reduce the osteogenesis inhibition of PDLSCs induced by high glucose. RT-PCR and western blot results showed that Ex-4 increased the osteogenesis-related gene expression of ALP, Runx2, and Osx, and upregulated the phosphorylation of P38, JNK, and ERK1/2; the peak effect was observed in the range 0.5–1.0 h. Mitogen-activated protein kinase (MAPK) inhibitors PD98059, SB203580, and SP600125 blocked the effects of Ex-4 on MAPK activation and decreased the expression of ALP, Runx2, and Osx in PDLSCs. Moreover, after Ex-4 treatment, the total β-catenin, p-GSK3β, LEF, and Runx2 protein levels increased under normal or high glucose environments. In conclusion, our results indicated that Ex-4 regulates the MAPK and WNT signaling pathways to alleviate the osteogenic inhibition of PDLSCs in a high glucose environment.
Always a Bridesmaid: A Machine Learning Approach to Minor Party Identity in Multi-Party Systems
Authors: French Bourgeois Laura , Harell Allison , Stephenson Laura , Guay Philippe , Lysy Martin
Published: April 2023

In multiparty systems, maintaining a distinct and positive partisan identity may be more difficult for those who identify with minor parties, because such parties lack the rich history of success that could reinforce a positive social standing in the political realm. Yet, we know little about the unique nature of minor partisan identities because partisanship tends to be most prominent in single-member plurality systems that tend toward two dominant parties, such as the United States. Canada provides a fascinating case of a single-member plurality electoral system that has consistently led to a multiparty system, ideal for studying minor party identity. We use large datasets of public opinion data, collected in 2019 and 2021 in Canada, to test a Lasso regression, a machine learning technique, to identify the factors that are the most important to predict whether partisans of minor political parties will seekin-group distinctiveness, meaning that they seek a different and positive political identity from the major political parties they are in competition with, or take part inout-group favouritism, meaning that they seek to become closer major political parties. We find that party rating is the most important predictor. The more partisans of the minor party rate their own party favourably, the more they take part in distinctiveness. We also find that the more minor party partisans perceive the major party as favourable, the more favouritism they will show towards the major party.
Cambodia in 2022
Authors: Loughlin Neil
Published: April 2023

The year 2022 began with a newly anointed leader-in-waiting in Hun Manet, the eldest son of prime minister Hun Sen. This formalized a process of hereditary succession underway for several years. Notwithstanding the prospect of change at the top, the authoritarian modus operandi of Cambodian politics continued in much the same way as in previous years, with government harassment of the opposition, a series of politically motivated court cases, and repression of civil society. Cambodia managed a relatively uneventful year as chair of ASEAN, but its international reputation was badly tarnished when its centrality to a surge in international criminal scamming operations and associated trafficking in persons shone a light on the corrupted nature of the country’s political economy. The economy began to recover from the effects of COVID-19, due in part to investment from China, but the consequences of the pandemic continued to be felt, particularly among poorer citizens.
Mongolia in 2022
Authors: Narangoa Li
Published: April 2023

As in 2020, the biggest stories in Mongolia in 2021 and 2022 were elections, COVID-19, and how to cope with the contracting economy. At the end of the year, Mongolia was struggling to meet public health challenges and to recover from the economic downturn. Both the government that was elected in 2020 and the president who took office in 2021 have promised to improve corruption, which is endemic in Mongolia, but people have yet to see much change. Popular dissatisfaction led to a huge public protest in December 2022 that demanded the government ensure more transparency in the coal trade. Thirty years after a peaceful transition to democracy, Mongolia is facing its greatest challenge: how to maintain and develop a transparent democracy that truly cares about public opinion and people’s livelihoods.
Experimental study of the uniaxial stress-strain relationships of parallel strand bamboo in the longitudinal direction
Authors: Sheng Baolu , Bian Yuling , Liu Yanyan , Chui Ying-Hei , Zhou Aiping
Published: April 2023

Parallel strand bamboo has extensive potential applications as a structural material for construction. Studying longitudinal stress-strain relationships is essential as a means to build a constitutive law for parallel strand bamboo composites and to conduct an inelastic analysis for structural members constructed by this material. For this reason, failure modes and the damage mechanisms were investigated for tension and compression in parallel strand bamboo composites in the longitudinal direction. An analytical stress-strain formula for the parallel strand bamboo composites was developed for tension and compression related calculations. Tensile failure was caused by the damage of the longitudinal fibers and showed brittle characteristics. The compressive failure resulted from the buckling of the fibers near the damage area. In addition, three types of failure modes were observed; longitudinal buckling failure, compressive-shearing failure, and longitudinal crush failure. The stress-strain relationship in the longitudinal direction of parallel strand bamboo composites exhibited linear behaviour for tension. However, the stress-strain relationship for compression remained linear within the proportional limit, while becoming nonlinear, which can be simulated by a quadratic polynomial, once the stress exceeded the limit. The experimental data agreed well with the model predictions, showing that the present model had high prediction accuracy.

Published: April 2023

Golf tees with a plastic head and wooden shaft were prepared by back injection moulding of a beech wood (Fagus sylvatica) shaft with different polymers (i.e. ionomer, polypropylene, and polyamide). In order to facilitate adhesion between the polymer melt and the wood surface, the wooden shafts were pre-treated with different primer substances, including a commercially available primer for ABS edges, a 10% solution of alkyl ketene dimer (AKD) in toluene and tumbling lacquer. The mechanical strength of the wood-plastic interphase was characterized by applying a pull-out test. Bond strength values of more than 9 N/mm² were observed for polyamide, whereas ionomer and polypropylene specimens achieved values between 0.7 and 3.8 N/mm². Surprisingly, the used primers failed to improve interfacial adhesion with the exception of the ionomer sample pre-treated with the commercial ABS-primer. Although light microscopy and SEM revealed some differences in the penetration behaviour of the different polymers as well as in the extent of plastic wood deformation imposed during injection moulding, the chemical nature of the polymer seems to be the most important determinant for the bond strength of wood-plastic hybrid components.
Coupling model of fuzzy soft set and Bayesian method to forecast internal defects of ancient wooden structures based on nondestructive test
Authors: Wang Ziyi , Wang Wei , Ma Donghui , Guo Xiaodong , Huan Junhong , Cheng Liting
Published: April 2023

In order to improve the detection precision of internal defect in the ancient wooden structures, defect simulation tests on pine and elm commonly used in ancient buildings were performed by using stress wave detection and drilling resistance detection. Based on detection data, three typical evaluation criteria, which are the information entropy, the correlation coefficient, and residual sum of squares, were selected as a priori information. Combining with the expert’s fuzzy evaluation value, Bayesian formula was used to modify the prior information to determine the weight coefficients of the two detection methods, and a combined prediction model was established. The results show that the combination of subjectivity and objectivity enables the revised weights to more reasonably and accurately reflect the relative importance of each detection method in prediction evaluation, which reduces the forecasting error. Specifically speaking, the mean error of the combined model was reduced by 49.8% and 59.8%, respectively, compared with stress wave detection and drilling resistance detection. Moreover, the five error indicators of this combined forecasting model are the smallest in all methods, indicating the proposed method has a better forecasting effect. It provides an effective application tool for the practice of forecasting the internal defects of wooden components in ancient buildings.
Kraft, BCTMP, and TMP dewatering behaviour along the axis of a screw press
Authors: El idrissi Bouchaib , Loranger Éric , Lanouette Robert , Bousquet Jean Pierre , Martinez Mark
Published: April 2023

The drainage- and dewatering-controlling mechanisms in a screw press were detailed in this work. Three pulps (kraft pulp, bleached chemi-thermomechanical pulp, and thermomechanical pulp) were studied to compare a wide range of wood fibre types. The dewatering was controlled by the screw press parameters and the pulps’ properties. Filtration was found to be the controlling mechanism in the first part of the screw press for the three pulps, and it was less important when the fines content was greater. In the compression zone, the degree of compression was affected by the pulp flexibility and the fibres’ tendency to entangle. Filtrate flow rate monitoring along the screw press could be a good indicator of where the transition from filtration to consolidation occurs. The pressure along the screw press did not change much in the filtration zone, and it notably increased near the discharge end. When the drainage was very high, the pulp feed increased, causing the pulp axial velocity in the end part to be greater than the screw’s linear advance.
Hydrochloric acid-catalyzed hydrothermal pretreatment of brown seaweed residues for enhancing biofuel production
Authors: Park Eun Young , Park Jung Kyu
Published: April 2023

The hydrochloric acid-catalyzed hydrothermal pretreatment of brown seaweed residues (Laminaria japonica) was optimized with respect to three operating factors: temperature, time, and the concentration of HCl, using response surface methodology (RSM). In order to confirm the significance of the quadratic model, an analysis of variance was performed, which resulted in an F-value of 11.09. Therefore, the regression model was highly significant. Additionally, the pareto chart was used to contrast the absolute values of the standardized effects. Response surface and contour plots were used to illustrate a surface with a maximum. The perturbation plot showed the sensitivity of the reducing sugars yield to the independent factors. Under the reaction conditions of 142 °C, 9 °C, 18.6 min, and 0.1 N HCl concentration, the experimental yield of 113.0 mg/g and the predicted yield of 107.5 mg/g were obtained.
Effects of using bark particles with various dimensions as a filler for urea-formaldehyde resin in plywood
Authors: Mirski Radosław , Kawalerczyk Jakub , Dziurka Dorota , Wieruszewski Marek , Trociński Adrian
Published: April 2023

The possibility of replacing the rye flour commonly used as a filler for urea-formaldehyde resins was investigated for plywood production with birch bark characterized by various particle dimensions. The effects on the curing and rheological properties of the adhesives were investigated. Moreover, the plywood was tested to evaluate the formaldehyde emissions, bonding quality, modulus of elasticity, and bending strength. The results showed that the size of the bark particles had a significant effect on the viscosity of the adhesives but did not affect other properties of the resin. Replacing the flour with the bark significantly decreased the formaldehyde release, but there was no clear correlation with the dimensional fraction of the bark powder. The particle size had notable effects on bonding quality and mechanical properties. The best results were obtained for a sieve with square holes whose inside lengths were 0.315; however, all plywood samples achieved shear strength values exceeding the requirements of EN 314-2 (1993).

Published: April 2023

Although there are literature studies on military uniforms, few investigate those used by the Military Police (MP). As such, the present study aimed to characterize the structural, colorimetric and mechanical properties of Brazilian MP Uniforms. To that end, yarn count, fabric weight, yarn density, weave pattern, optical microscopy, fastness, reflectance spectrophotometry and tensile strength tests were performed on uniforms from MPMG, MPSC and MPRN (Military Police from the states of Minas Gerais, Santa Catarina and Rio Grande do Norte, respectively). Structural similarities between the MPMG and MPSC uniforms were detected, and significant differences in relation to the MPRN. The three uniforms displayed satisfactory performance in dry rubbing fastness, and unsatisfactory in wet rubbing fastness and loss of color after washing. Thus, there is significant room for improvement in military police uniforms in Brazil.
Relação entre Planejamento Estratégico e Cultura Organizacional

Published: April 2023

As empresas não são organizações isoladas, isso faz com que os problemas de cunho social, político, regulamentares e de cidadania, façam a delimitação das ações durante o processo estratégico, pontuando o que uma empresa pode ou não deve fazer. Neste contexto, entra em destaque a cultura organizacional, que é um fator de grande importância durante o planejamento estratégico, pois possui influência no processo de tomada de decisão da empresa. Desta forma, o presente trabalho tem o objetivo de analisar a ligação existente entre o planejamento estratégico e cultura da empresa, levando em conta como essa relação poderá trazer resultados expressivos para o sucesso organizacional. Para tanto, foi utilizada a pesquisa bibliográfica, sendo pesquisados livros, artigos, periódicos, revistas, sites da Internet e entrevista. Conclui-se que, tanto a fala do entrevistado como o material bibliográfico analisado estão aliados a ideia de que alterar a cultura é muito difícil, tarefa que acaba requerendo de um grande empenho, tempo e dedicação. Mas sem alinhar a cultura e o planejamento estratégico, a organização enfraquece, uma vez que o intuito não está segundo as crenças e valores que a empresa possui. Isso tudo, tem reflexões numa falta de compromisso através do colaborador, pois ele de determinada maneira, não está com satisfação em seu ambiente de trabalho, devido ao fato de não ter identificação com o que a empresa pretende atingir no futuro.

The Miserable with a Human Soul: Portrayal Modes in Works by F. Dostoevsky, N. Nekrasov, and F. Reshetnikov
Authors: Sozina Elena
Published: April 2023

This article deals with the tradition of portraying “miserable”, “minuscule”, “tiny”, “poor”, “downtrodden” people in Russian literature between the 1840s and the 1860s. F. M. Dostoevsky, through the main character of The Idiot, called them “a misère” with a “human soul” and considered “the restoration” of the “ruined” the main idea of the art of the entire nineteenth century. The starting point of the research is Poor Folk, Dostoevsky’s novel of the natural school period in which the writer reversed sentimentalist poetics following the new demands of literature, emphasising the socio-economic meaning of the “poor folk” concept. In the 1860s, Dostoevsky’s sentimental-naturalistic style changed, and his feuilletons from the Petersburg Dreams, the discourse of poverty began to sound ironic; it was partly due to Dostoevsky’s polemical tasks. There is a connection with N. A. Nekrasov’s poetry in the middle of the century. It traces the change in the modality in the depiction of the “miserable” and the lower strata of the population from sympathetic drama to irony and sarcasm, which accompanies not so much the images of the poor themselves as the presence of the theme in literature, its traditionally philanthropic and sentimental personification. The material of the analysis in the article is In the Street and About the Weather, Nekrasov’s poetic cycles of the 1850s–1860s, most vividly depicting the images of the “poor folk” in St Petersburg’s streets and “Petersburg slums”. The third writer to focus on the urban poor, inhabitants of the basement slums is F. M. Reshetnikov with his story Yashka (1868). This writer’s story of entering the sphere of literature was comparable with that of the first edition of Dostoevsky’s novel. Reshetnikov himself, judging by his letters and diary, sometimes resembled the “miserable” characters of his much more famous and successful contemporary. Starting from the traditional forms of the author’s emotional experience for the character thrown to the bottom of life, Reshetnikov’s naïve and simple-hearted writing imitated normality, the commonness of the terrible life of his characters, concealed the warmth and human pain that the reader was supposed to perceive. It brought his “miserable” wordless characters closer to the author, and therefore to the reader, opening new possibilities in the literature that would be developed by writers of the turn of the century.
The First Days of the Soviet Theatre: Stanislav Vinaver’s Dramatic Testimonies
Authors: Ičin Kornelija
Published: April 2023

Stanislav Vinaver witnessed October Revolution. In April 1917, he was sent to Russia on a diplomatic mission and stayed there until the autumn of 1919. After returning to Serbia, he published articles about Russia (ideology, revolution, war, life, theatre, art, music) in Politika and Republika, Belgrade daily newspapers, and in Kritika, a Zagreb magazine, which, in their form, resembled dramatic sketches, stories, reports, and travel essays. This paper discusses Vinaver’s articles on theatre issues in Bolshevik Russia, primarily the Kamerny Theatre and the Moscow Drama Theatre. Vinaver’s ideas about the repertoire and aesthetic searches of the two Moscow theatres are interpreted in the context of the time of their emergence, together with the context of artistic assessment, which is by no means inferior to today’s interpretations of the role of the Kamerny and Moscow Drama Theatres in the development of the Soviet experimental theatre.
The Scary in Acmeist Poetry as a Marker of Modernist Artistry
Authors: Vasiliev Igor
Published: April 2023

In its self-affirmation in the cultural field and its defiance of the extremes of Symbolism, Acmeism insisted on the diversity of its creative possibilities, the preference of the worldly content to the otherworldly, the development of a clear and transparent artistic form, the self-identity of artistic realities, and their balance. All this testified to the tendency to classical artistry, which determines not only the form of works (language and poetic style, composition) but the content (circle of ideas, problems, themes and images, and plot). The author examines how this system comprehends the chaotic and disharmonic that are part of life within its boundaries of cosmographic properties (harmonious, bright, optimistic). Earthly life as a reality declared a priority in the Acmeist paradigm is full of hostility, threats, and danger. Also of interest are the questions of how the negative category of the scary manifests itself and whether its presence testifies to the connection of Acmeism with the non-classical artistry of modernism. Answers to these questions form and represent the problems of this article. Referring to the works of N. Gumilyov, A. Akhmatova, and O. Mandelstam, the author explores the image and artistic understanding of the scary in Acmeist poetry. The article demonstrates a variety of objects, phenomena of reality, life processes, connections, and relationships that cause unpleasant feelings and experiences in poetic perception. On the one hand, the poets’ fears are due to personal characteristics and predilections, i. e., they have an individual nature and, on the other hand, they express the general tendencies of Acmeism. For Gumilyov, the dangers are associated with his love of travel. Hence the presence of a spatial component in the adventurous topic of his poems: the characters participate in battles with the sea, evil animals – the inhabitants of the African savannah, fantastic creatures, for example, with a dragon, visit the afterlife. The fears of Akhmatova’s lyrical heroine are motivated by dramatic collisions of the interpersonal, primarily love and relationships. The terrible thing for Mandelstam lurks in the fatal illness predicted to him, the sacred depth of religious faith, and the collapse of the world of cultural values that feeds his spiritual self-sufficiency. Acmeists were not afraid to depict and comprehend death, bearing the emptiness of non-existence, promising a frightening collision with the unknown and otherworldly, and plunging into a stupor of hopelessness. The scary made it possible to expand the thematic and pictorial possibilities of the works, address sociocultural issues, and reflect the tragedy of life becoming a marker of the high standard artistry of modernism.
The InVersiya Poetry Festival: The Creativity of Communication and Collective Authorship
Authors: Barkovskaya Nina
Published: April 2023

This article analyses three projects created within the framework of the Chelyabinsk poetic laboratory festival InVersiya (photograph album Developer, calendar Dogs and Baobabs, and the film Walking Man) in the aspect of the features of modern media poetry in its regional refraction. Poetry festivals are characterised by a combination of experimentation and accessibility to the public, the subordination of individual poetic ideas to the general conceptual framework of the project, and quite often the dominance of creativity over artistry, performativity, and procedurality. The InVersiya festival is a part of the Ural poetic movement, which is quite developed today. The author concludes that the Ural authors are open to interaction with poets and artists from other cities and countries, overcoming the complex of “provinciality”, fitting into the all-Russian poetic context. The analysis of the projects the author refers to demonstrates the dominance of the communicative function of poetry and the importance of the pragmatics of the poetic text. The article examines specific methods of interaction between verbal and visual components, revealing strategies of collective authorship. According to the author, among the “Ural” poetic traditions proper, one can name the preservation of the dual addressing of works (elitist and mass), the implicit presence of the gender and environmental components of the figurative range, and a drive towards experiment.
Verbs of the Emotional States of Shame and Embarrassment in Russian: A Diachronic Aspect
Authors: Kalyuga Marika
Published: April 2023

This article is devoted to the description of verbs of the emotional states of shame, embarrassment, and shyness in the diachronic aspect. The relevance of the research is due to the need to expand knowledge about the dynamic changes in the vocabulary of emotions, and the impact of cultural and political transformations on these changes. Although semantic differences in Russian expressions for shame-like emotional states have been well studied, diachronic changes in the meanings of these expressions have received little attention. The scholarly novelty of this work is determined by the fact that it examines the diachronic development of the verbs for these emotional states, which occurred in the Russian language in the eleventh–twenty-first centuries, and the factors that caused these changes. The data have been collected from explanatory dictionaries of the modern Russian language, etymological dictionaries, and historical dictionaries of different ages and coverage, as well as the National Russian electronic corpora. The material for the study was data from explanatory dictionaries of the modern Russian language, historical, and etymological dictionaries of the Russian language, as well as data from the National Corpus of the Russian language. The theoretical basis of this research was formed by works in the field of the linguistics of emotions and linguistic culture. The main research methods were the contextual-functional method, as well as etymological analysis. This study demonstrates that in the process of the semantic development of the verbs of shame and embarrassment in the Russian language, both general tendencies towards a decrease in the polysemy of semantically overloaded linguistic structures and tendencies towards a more accurate and precise labelling of various aspects of emotional states play an important role. It is shown that during the semantic development of words denoting shame and embarrassment, the polysemy “to be shameful” / “to feel shame” was gradually lost and the polysemy “to be ashamed” / “to be embarrassed” decreased in use. The article also describes the main patterns of semantic derivation that are typical of verbs of shame and embarrassment, which appear in the Russian language of different centuries.
The Manuscript Tradition of The Third Redaction of the Russian Chronograph. Continuing A. N. Popov’s Research
Authors: Bogdanov Andrey
Published: April 2023

This article aims to draw scholars’ attention to the study of The Old Russian Chronograph of the Third Redaction, a work of Russian culture that provides a profound idea of the spiritual world of the people of the seventeenth century. An archaeographic sketch provides a key to the study of the manuscript tradition initiated by A. N. Popov 150 years ago. The author examines 47 major codices (not counting excerpts) attributed to each of the three editions of the Chronograph, which was created in the 1640s and became extremely popular with scribes later. The author reveals 25 of the 31 manuscripts used by Popov. Another 22 archival codices were added to them. For many of them, the author managed to establish the time frames of emergence and identify their creators and owners. The archaeographic data show the growing interest in the work from 1645 to the turn of the eighteenth century among all strata of society. Diocesan bishops and important monasteries (Chudov, Novospassky Siyskiy, Makaryev Zheltovodsky), boyars, many stolniks, priests, merchants, and townspeople tried to acquire The Chronograph. They rewrote and enlarged it showing enviable creativity in all parts of the country, from Moscow to Bryansk, Beloozero, and Kholmogor. The article provides a description of the sources that have now become available for study.
Dialogic Aesthetics in Boris Zaitsev’s Russian-Italian Text
Authors: Zhukova Olga
Published: April 2023

This article examines the interconnection of the images of Russia and Italy in B. K. Zaitsev’s artistic consciousness revealing their ideal-forming meaning and studying the literary and aesthetic concept of the writer. It is argued that the themes of Russia, Italy, and Florence dominate in the writer’s work, making up the internal semantic unity of his multi-genre texts. The “Florentine text” is interpreted as a local textual subsystem of the “Italian text”, which is a dialogical element of the Russian-Italian text (super-text) created by the writer throughout his artistic life. According to Zaitsev, the city of Dante formed his aesthetic experience, his spiritual, and intellectual identity. Building a dialogue between Russian literature and Dante’s work, Zaitsev follows the philosophical and aesthetic programme of Russian Europeanism characteristic of the Silver Age culture. In the article, the author develops the thesis about the relationship between the image of Russia and that of Florence in the artistic consciousness of Boris Zaitsev. It is demonstrated that the study of Zaitsev’s “Florentine text” provides an idea of the semantic conditionality between the leading Russian and Italian themes in the writer’s work that define his aesthetic concept as dialogical. To achieve this goal, the paper analyses Zaitsev’s artistic and documentary evidence about Florence and the features of his aesthetic reception of the culture of Russia and Italy. The article focuses on the method of literary mnemonics developed by the writer. With its help, Zaitsev creates an authorial version of the myth of Florence in the context of Russian and European literature. The reconstruction of the historical and ideological context of Zaitsev’s work proposed in the article makes it possible to understand the artistic and philosophical nature of his works addressed to Russia and Italy more accurately. As a result of the study, the author determines the structure of the dialogical interactions of imaginative and semantic elements of Zaitsev’s Russian-Italian narrative. Russian and Italian themes that form the dialogical integrity of the Russian-Italian text in the writer’s work are a key aspect of our understanding of B. K. Zaitsev’s artistic concept from the point of view of literary theory and aesthetics.

This article reviews Svyatopolk-Mirsky, a book by M. V. Efimov and G. Smith published by Molodaya gvardiya in the Lives of Remarkable People series (2021). It was written by the oldest English specialist in Russian literature Professor G. S. Smith and a well-known Russian researcher of the literature and culture of Russia abroad M. V. Efimov. Both have studied the life and literary legacy of the character of their book for many years. For the first time in Russia, using the Russian and European tradition of biographical studies and historical-literary, cultural, and textual practices, the authors have carried out a full-scale reconstruction of the biography of one of the most striking and enigmatic figures of the first wave of the Russian emigration. The authors of the book introduce a significant scope of archival materials and memories of contemporaries, hard-to-access English and émigré periodicals, and other sources into scholarly circulation. It makes it possible to create a detailed account of the main events of prince D. P. Svyatopolk-Mirsky’s life – from his childhood to his tragic death in the Magadan camp, dramatic twists of fate and the reasons behind them, his close circle and distant environment, the political, historical, cultural, and literary context of the events described. The biographers’ interest in the inner world and the psychology of Svyatopolk-Mirsky’s actions is combined with a subtle philological analysis of his literary criticism and studies. According to the reviewers, the book is a major event in the Russian literary, political, and cultural history of the 1920s–1930s.
Systematics of the Plumeweeds: The Genus Carminatia (Eupatorieae, Asteraceae)
Authors: Hinojosa-Espinosa Oscar , Potter Daniel , Villaseñor José L.
Published: April 2023

Abstract— The genus Carminatia, which occurs from the southwestern United States to Central America, comprises annuals with cordate to broadly ovate leaves, paniculiform capitulescences that are often spike-like or narrowly raceme-like and with mostly fasciculate
capitula, and a pappus of plumose bristles. We used nuclear ribosomal DNA (ITS and ETS) and the plastid psbA-trnH spacer DNA sequences to estimate phylogenetic relationships among the species of Carminatia, which have not been fully investigated using molecular data to
date. All of our analyses supported the monophyly of the genus and most of them supported Brickelliastrum as sister to Carminatia. The analyses also supported the recognition of a new species, C. balsana, which is confined to the Balsas Basin
in Mexico. The new species is more similar to C. recondita, but has shorter capitula, corollas, and cypselae, and the capitula are oriented to more than one side of the capitulescence. An updated taxonomic revision of the genus, including morphological descriptions, a key to
the species, distribution maps, and images is provided.
Exploring Hanok accommodation‘s survival characteristics and determinants of the survival
Authors:   The Tourism Sciences Society Of Korea, Choi Nu-Ri , Kim In-Sin
Published: April 2023

This study aims to estimate the survival function of the Hanok accomodation and examine its key survival factors. Using the data made publicly available by the government, we examined a sample of 1,880 Hanok accommodations operated between 2009 and 2021. The estimated overall survival function suggested that Hanok accommodations were exposed to the risk of business closure immediately after opening, and the survival rate continuously decreased every year rather than plunging at a specific point. The Kaplan-Meier analysis showed that the survival rate differed based on location, certification, safety/hygiene, and historical variables. The Cox regression model indicated that the survival of Hanok accommodations depended on location, density, land-use suitability, certification, and safety/hygiene. These findings can help better understand Hanok accomodations’ survival factors and provide significant implications for the survival of Hanok accommodation. Furthermore, this study provide the government and Hanok accomodation hosts with practical solutions to improve the survival rate of Hanok accommodation.

Authors:   The Tourism Sciences Society Of Korea, Lee Hye-Jeong
Published: April 2023

The aviation industry faces challenges due to COVID-19, low global growth, and fierce international competition. As the significance of human resources as a response strategy rises, it is time to focus on the roles of the Department of Aviation Service, which was established to cultivate competent aviation industry professionals. Thus, this study examined the job experiences of recent graduates of the Department of Aviation Services who joined an aviation company as Cabin Crew shortly after their graduation using the situational learning theory as a theoretical lens. The study was conducted over a ten-week period, from May 1, 2021, to June 26, 2021, using in-depth interviews to collect data. Four categories were identified as a result of the analysis: effort and sense of achievement towards a career roadmap, ontological transformation process in the organisation, conflict to acknowledge the existence of 'I' in a conflicting organisational culture, and formation of the corporate identity through membership acquisition. Theoretically, the existing theory was supported and expanded by approaching the contextual learning and meaning of Cabin Crew in the workplace via legitimate peripheral participation. On the basis of the practical implications posed by IT-literate generations, a course of action was developed to foster online mentor-mentee relationships, online group learning, and an improvement in the culture of hierarchical organisation. It entails giving feedback on work that is straightforward and easy to understand, as well as adhering strictly to the manual.

The relevance The converter with reverse power transmission (with locked power transistors) is one of the most popular topologies of DC voltage pulse converters. The topology of the reverse-pass converter is unique in terms of the effective interconnection of electromagnetic processes in it. The undoubted advantage of the converter is its extreme simplicity and cheapness, the scope of its widespread use is limited to devices of low and medium power, both standard and non-standard applications. However, some properties of the converter make it possible to effectively solve complex problems of building powerful converter devices. In general, the development and research of reverse-flow converters is an urgent task in improving the devices of modern conversion technology. Aim of research Simulation of a reverse-flow converter with a high-speed dual-circuit current and voltage control system. Research methods The research methods of pulsed power electronic devices, methods of studying digital devices on CMOS structures (metal-oxide-semiconductor) are used in the work. The computer simulation was performed in the Electronics Workbench software environment. Results Methods of constructing a high-speed control system for a reverse-flow converter based on the use of two current and voltage control circuits are proposed. Due to the proposed methods, the speed and stability of the converter increases, protection against short circuit and excess voltage at the output of the converter is provided. The results and conclusions are confirmed by modeling.

The relevance Cleaning of bulk agricultural products from metallomagnetic impurities is an urgent problem that needs to be solved today, as it leads to significant material and economic losses. Magnetic and electromagnetic purification methods are based on the difference in the magnetic properties of the separated products, mainly on the difference in their magnetic susceptibility. In the working area of the separator, there is a zone of attraction of magnetic particles, the height of which is determined by the minimum distance between the working body and the surface of the fixed pole, and the zone of transportation of the magnetic product to the unloading site. The magnetic field in the working area of the separator is created by systems of permanent magnets or electromagnetic systems with winding. Parametric design is the basis for conducting design work during the development of an electromagnetic separator and allows you to clarify the final purpose of the installation already at the early stages of the project. Aim of research This article deals with optimization of design and mode parameters of electromagnetic separator with permanent magnets. Research methods In this study it is proposed to use nomogram-parametric design, both electromagnetic separator and its mode parameters. Nomogram parametrization consists in creating a nomogram to determine the mode parameters of electromagnetic separator with permanent magnets. Results Based on the established relationship of design and mode parameters of separation in the separator's working zone, a nomogram was developed that allows to determine the parameters of the electromagnetic system, the value of magnetic induction, depending on the heterogeneity of the magnetic field, as well as solve the inverse problem, determine the design parameters of the working zone with the given indicators of the electromagnetic system.

The relevance One of the key directions of innovative development of the electric power industry until 2035 is the transition to digital active-adaptive networks with a distributed intelligent automation and control system. In this regard, in conditions of increasing demands for improving the quality of electricity and reducing losses in networks, it is necessary to improve the voltage and reactive power regulation system in electric networks, which should be based on the widespread use of modern means of regulating voltage and reactive power, as well as automatic control systems, including centralized ones. The main effect of reducing technical losses in electric networks, as shown by the energy survey of FGC UES JSC, the experience of foreign electric grid companies and the analysis of the modes of operation of the Unified National Electric Grid, can be obtained by optimizing the established modes of operation of the electric grid in terms of reactive power and voltage levels in automatic mode, provided that the condition of regulating devices is constantly monitored. The absence of a system for remote monitoring of the parameters of power factor correction devices in the power supply systems of enterprises leads to untimely detection and elimination of failures in the operation and operation of the network without power factor correction. Aim of research To analyze the energy parameters of the power supply system of oil production facilities, to identify deviations of voltage values and power factor from regulatory requirements. To investigate the effectiveness of the use of low-voltage automatic power factor correction units in the power supply system of an oil-producing enterprise. Research methods The study of scientific literature, field research at oil pumping facilities, energy surveys, computer modeling. In order to identify the technical and economic efficiency of the use of low-voltage automatic power factor correction units, pilot field tests were conducted in one of the oil and gas producing enterprises of the Tatneft PJSC. Results Energy surveys of in-field pumping facilities, oil treatment and reservoir pressure maintenance of Tatneft PJSC have shown that the value of reactive power in the networks of power supply systems of these enterprises significantly exceeds the standard. As a result of pilot field tests, it was revealed that the use of automatic power factor correction units in automatic mode ensures the stabilization of the power factor at the level of standard values, excluding under-compensation or overcompensation of reactive power, while reducing electricity consumption by an average of 2.4 %. The remote monitoring system allows you to monitor the operating mode and technical condition of all elements of the capacitor plant, timely perform maintenance of contactors to ensure the operability of the installation.
