Published: October 2023

У зв’язку з підвищенням маневрених можливостей сучасних повітряних об’єктів задача оцінки стійкості супроводження радіотехнічними слідкуючими системами багатоканальної радіолокаційної станції є актуальною. Зрив супроводження є неприпустимим для радіотехнічних систем радіолокаційних станцій, коли пуск зенітних ракет зроблений і вони будуть втрачені, або призводить до необхідності витрати часу з випромінюванням радіолокаційних станцій для допошуку і чергового захоплення на супроводження повітряних об’єктів. Для аналізу стійкості супроводження необхідно або проводити моделювання функціонування радіотехнічних слідкуючих систем із використанням статистичних характеристик реальних дискримінаторів, або використовувати методику, засновану на використанні їх еквівалентних дискримінаційних і флуктуаційних характеристик, що суттєво спрощує аналіз зриву супроводження в слідкуючих системах, але за умови, що додатковою інструментальною помилкою можна знехтувати. У роботах при визначенні еквівалентних характеристик дискримінаторів важливим параметром є дисперсія помилки за межами апертури еквівалентної флуктуаційної характеристики, що може вплинути на результат наявності зриву супроводження, або повернення помилки в межі апертури характеристики дискримінатора. Стосовно до параметрів еквівалентних флуктуаційних характеристик, запропонованих в попередніх роботах, їх оцінки досить грубі, та не враховують багатьох параметрів, що можуть на них впливати. В статті уточнено значення дисперсії помилки за межами апертури еквівалентної флуктуаційної характеристики дискримінатора. Для розв’язання задачі аналізу можливого зриву супроводження в радіотехнічній слідкуючій системі по радіальній швидкості отримані значення дисперсії помилки вимірювання за межами апертури еквівалентної флуктуаційної характеристики частотного дискримінатора.

Authors: Cherif Daia Eddine Oussama Mohamed , Chebabhi Ali , Kessal Abdelhalim , Fellah Mohammed Karim , Benkhoris Mohamed-Fouad
Published: October 2023

The energy provided by the PV system is strongly influenced by climatic conditions such as solar radiation and cell temperature. A suitable DC /DC converter and a robust control strategy combined with the maximum power point tracking (MPPT) algorithm are required to harness the maximum power of the panel. This paper proposes a super-twisting integral sliding mode control (ST-ISMC) for four legs interleaved boost converter (FLIBC) as an interface to the MPPT algorithm for a 60 KW PV system. The FLIBC has been used to overcome the drawbacks of the conventional boost converter (CBC). The ST-ISMC is proposed to maintain the PV voltage track the reference provided by the MPPT algorithm and ensure the equal sharing of input current between legs. The controller gains of the proposed ST-ISMC have been calculated using the grey wolf optimization algorithm for better performance. The simulation results prove the excellent performance of the proposed controller over the conventional controller.
Enhancing the bearing capacity of friction anchor bolts through cementitious concrete injection for reinforced support in underground mine
Authors: Amıne Soufı
Published: October 2023

Friction anchor bolts are commonly used for providing support in underground structures by relying on frictional forces between the bolt and the surrounding rock. This study proposes a method to enhance the efficiency of these bolts by injecting a cement-based mixture comprising cement, sand, and additives. The injection of this mixture into the bolt results in internal expansion, which reinforces the friction and bearing capacity of the bolt. The increased volume exerts a radial force, leading to improved adherence, load transfer, and void filling. Pullout tests were conducted on various rock masses to evaluate the performance of the anchor bolts. The results demonstrate increased pullout resistance with higher rock mass quality and longer cemented bolts. Additionally, the use of a silicate-based additive accelerated the curing time of the cement, enhancing the strength of the bolts. The study also highlights the significant influence of groundwater on the bearing capacity of the bolts. These findings indicate the effectiveness of cemented concrete injection in strengthening friction anchor bolts and their anchorage in underground structures.

Published: October 2023

In this work, the use of water (W) as a grinding additive in addition to waste/by-products such as olive black water (BW) and residue of olive black water (RBW) in calcite dry grinding to be sized in microns was investigated at a laboratory scale. The test results were evaluated based on product fineness, grinding time, liquid material dosage, and powder flowability. The study revealed that the use of any kind of liquid materials tested improved the grinding process compared to the blank condition. Considering RBW, powder flowability increased as its concentration increased. The findings from both the BW and W data revealed that the dose increase does not yield favorable outcomes in relation to the ffp index. Nevertheless, there was a noticeable enhancement in particle fineness.

Authors:   Korean Association for Qualitative Inquiry, Lee Yoonhee , Yang Myonghee
Published: October 2023

This study is about the experience of transitioning from integrated education to separate education in the life of students with disabilities through the mother of students with developmental disabilities. It was intended to examine how they experienced the beginning, interruption, and new beginnings of integrated education in separate education, and to find out what those experiences mean in their life stories. First, when students with developmental disabilities entered the school, they were denied admission because they could not provide a special class for one person even if they wanted to go to a nearby school. Second, teachers had a very important influence on the decision of the parents of students with developmental disabilities to transfer from integrated education to separate education. Third, the mother of a developmentally disabled student who could not speak felt anxious because she did not have the information she could receive from her children and chose to transfer for safety. Fourth, there is no curriculum for special education, and the special needs of students with disabilities have not been satisfied in the form of following general education. Fifth, special schools are comfortable because of the legitimacy of being a space for students with disabilities. Among the non-disabled students in the integrated class, students with disabilities seemed to be too prominent and damaging to others. As a result, the participants paid more attention and effort than they should as ordinary parents, and they lived under the name of the mother of a disabled student, not themselves. She chose to separate herself without expressing the feelings she experienced because she was not rejected and consoled, and was personally isolated. Sixth, people cannot empathize because developmental disabilities are not visible on the outside. Due to the knowledge-oriented school atmosphere, non-disabled students changed to a more negative attitude toward disabled students as they became seniors, unlike in the lower grades.

Authors: Ragulin Vitaliy , Yaryzhko Aleksandr , Nazarko Olga
Published: October 2023

Problem. The pace of road construction and reconstruction dictates high requirements for modern equipment, and in most cases the requirements relate to work equipment. When performing technological operations, external loads are transmitted through the main working body to all elements of work equipment, components and parts of the machine as a whole. Methodology. The use of software products makes it possible to preanalyze any combinations of design, modeling, as well as strength studies and strength testing. On the basis of the obtained data, it is possible to analyze the load in the nodes of the metal structure of the working equipment without conducting field tests. The work is a continuation of previous studies using computer modeling methods in the engineering industry. Designing or modernization of technical objects at the moment is impossible without creating three-dimensional models. The purpose of this work is to develop a digital model of the telescopic loader equipment in the "Dynamic Simulation" environment of the Autodesk Inventor software package, to perform research on the kinematics of movement and load modes of individual elements. The use of telescopic working equipment expands the capabilities of front loaders on a wheel base, but in turn, leads to an increase in material costs during design and production. Results. The process of separate scooping of bulk material in a stack is considered, which consists in introducing a bucket into the stack with a progressive movement followed by stopping the loader and turning the bucket. Originality. The main forces acting on the working equipment during the rotation of the bucket and the boom during the scooping process are the gravitational forces of the elements of the working equipment, non-conservative forces arising in the cylindrical surface of the section and the normal force from the side of the wall of the stack of material. Practical value. External loads are applied to the edge of the bucket. Their direction depends on the trajectory of the working equipment and in the process of simulation they changed depending on the current vertical coordinate of the cutting edge of the bucket.
Simulation of turning traffic at a controlled inter-section
Authors: Ryabushenko Olexander , Prosvirnin Olexander
Published: October 2023

Problem. Optimizing the parameters of traffic light regulation can reduce delays and queues of vehicles, increase the throughput of intersections, and thus increase the quality of the functioning of the city's transport network. This question is especially relevant for Ukraine, because in these conditions it is impossible to carry out a significant modernization of the city's transport network, but within the framework of the post-war reconstruction of the city, it is possible to carry out the improvement of the geometric parameters of the intersection. However, among all the factors that affect the throughput of a regulated intersection, in the scientific literature and normative documents, insufficient attention is paid to the geometrical parameters of the intersection itself.  Goal. The geometric parameters of the intersection first of all affect the characteristics of the movement of the selected rotating streams, and through this - the saturation of the stream. Therefore, it is of interest to simulate the movement of turning traffic at an intersection and compare the results with empirical models. Methodology. To estimate the permeability of the selected turning lanes, the correction of the ideal saturation flow is most often used with coefficients, the values ​​of which are either calculated depending on the geometric parameters of the intersection (for example, F. Webster's methodology), or are taken as constant (Posіbnik НСМ 2000). The flow saturation value for the selected turning lane was also calculated taking into account the minimum safe distance of the vehicles in the traffic flow. It is shown that these methods give different values ​​of flow saturation. Results. To check the degree of influence of the rotary flow traffic radius on the flow saturation of the selected traffic, simulation modeling of the robot of the conditional adjustable intersection was carried out in the program PTV VISSIM. The parameters of the model were chosen in such a way that a sufficiently long queue was released before the stop line. In the process of imitation, after turning on the green signal, the virtual detector fixed the number of cars that passed through the dedicated right-turn lane. Practical value. The results showed that for selected turning lanes, the saturation flow increases with an increase in the radius of the turning flow trajectory, which corresponds to the classical formula of F. Webster, when the radius value is up to 15 m. Therefore, adjusting the saturation flow for selected turning flows is appropriate this time. When the flow moves along a path with a larger radius, the saturation flow does not depend on the geometry of the intersection.

Authors: Horbachov Peter , Chyzhyk Vitalii
Published: October 2023

Problem. The task of determining the annual volumes of public transportation in a city is relevant when addressing almost any issue related to processes in the field of public transport, as it provides decision-makers with data on the actual state of passenger traffic on the routes. These data reflect the current operating conditions of carriers and the level of passenger service and thus present the extent to which public transport is fulfilling its primary task of providing transportation for the population. Goal. The goal is development of a methodology for calculating annual passenger transportation volumes based on a sample tabular survey of urban routes. Methodology. The paper presents a methodology for transitioning from passenger transportation volumes obtained based on field observations of public transport operations to annual transportation volumes. The reliability of the forecast can be improved by estimating probabilistically the boundaries of the interval of possible values of the on-time traffic volume and accepting the lower boundary of the interval as a guaranteed estimate of the desired value of the traffic volume with a given probability. Results. A methodology has been developed that allows predicting the annual volume of passenger transportation by urban transport based on sample observations. It allows you to estimate the guaranteed volume of public transportation in the city for a year with a given probability, which provides the customer with additional information when forecasting the annual volume of public transport work based on the average value. Originality. The presented methodology consists of the new transition method from sample daily volumes of passenger transportation to total annual volumes. Practical value. Forecasting the volume of the passenger transportation is the most influential component in setting tariffs for transportation services. The developed methodology allows obtaining the required values of annual volumes with a high degree of accuracy, based on actual transportation volumes, and is of practical interest to local authorities.
Some approaches to the development of resources for self-directed learning of foreign languages in a technical university
Authors: Saienko Natalia
Published: October 2023

Problem. The rapid development of technology leads to the obsolescence of professional knowledge by the time students graduate from institutions of higher education. In addition, some acquired competences, as, for example, in foreign languages, need constant refreshing after students leave the classroom, otherwise there is a threat of their complete loss. This causes the active search for innovative pedagogical approaches that would ensure the continuity of education of university graduates, one of which is a self-directed learning, which is considered as independent study of additional material in relation to the main course, as a learning process in which students take responsibility for their own learning, setting their goals, developing and planning their own training program and evaluating the results of their activities. Goal. To determine the essence of self-directed learning, to analyse the peculiarities of self-study of foreign languages, to propose new approaches to its organization using innovative tools in the digital environment of a technical university. Methodology. The following features of self-directed foreign language learning are highlighted: the self-directed learning process is initiated by the students themselves and is carried out according to their plans, the teacher’s activity has an evaluation and stimulating character; learning goals are put forward by students based on personal needs; in self-directed learning, it is not the amount of knowledge that is important, but the ability to use it independently; students find sources of explanation of unfamiliar material on their own; the main way of determining the effectiveness of self-study is the ability to practically apply the learned material in professional and everyday activities. The students were offered a number of courses designed for independent study using the method of audiovisual translation, which, as a modern trend in linguistics, is rapidly developing as digital technologies are constantly improving. This method was adapted for our purposes using parallel translation of lexical items and texts, which were voiced and placed on the YouTube platform. Results. The volume of training lexical and grammatical tasks, which students perform independently, was increased, and the opportunity to independently study a significant number of socio-cultural and professional topics was provided. Originality. The double presence of lexical items, available both as symbols on the screen and as a sound series, helps students refresh and consolidate it, and parallel translation gives them a full understanding of the statement in the shortest possible time. Practical value. The proposed approach with the usage of audiovisual translation has a great potential in the field of self-directed learning of foreign languages, as it offers a variety of convenient, affordable and accessible digital resources for self-study.

Published: October 2023

Problem. The problem is unavailability of inexpensive ZnSe nanocrystals for hot-pressed ceramics of the Cleartran or Multispectral classes. Goal. The goal is to investigate and improve the structural features of ZnSe nanocrystals obtained by combustion synthesis during annealing in air or nitrogen. Methodology. ZnSe nanocrystals were characterized by combustion synthesis using electron scanning microscopy, X-ray diffraction analysis, electron paramagnetic resonance, and photoluminescence analysis. Results. To improve the spectroscopic properties of ZnSe nanocrystals were synthesized by combustion synthesis method (self-propagating high-temperature synthesis) with different initial current pulses, a series of thermal annealing was carried out in the temperature range Т = 200 ÷ 800 °С with a step of Т = 100 °С at atmospheric pressure, in air or in nitrogen. The developed approach makes it possible to obtain the investigated ZnSe nanocrystals with specified properties by controlling their crystal structure. The dependences of the structure, characteristics of the magnetic field, and hyperfine structure of electron paramagnetic resonance, photoluminescence spectra during annealing in air or nitrogen from temperatures of annealing were obtained. In comparison with the initial charge, the size of nanocrystals grows by ~ 20 %, the fraction of the cubic phase increases, the parameters of nanocrystals lattice grows, and the number of dislocations and microstress decrease after annealing. It is recommended to use a current pulse of ~ 40 A, and then perform annealing at a temperature of T = 800 °C in nitrogen for the synthesis of ZnSe nanocrystals with a more perfect structure. Originality. The annealing of ZnSe nanocrystals obtained by combustion synthesis in air or nitrogen was studied. Practical value. The obtained results allow using the synthesized ZnSe nanocrystals by combustion synthesis method for various optoelectronic devices or for obtaining hot-pressed ceramics of the Cleartran or Multispectral classes.

Authors: Hlushkova Diana , Bagrov Valeriy , Volchuk Volodymyr
Published: October 2023

Problem. The paper considers the influence of wear on the formation of a "white band" in metastable austenitic, martensitic-austenitic and secondary hardening steels of the Cr-Mn-Ti system additionally alloyed with Mo, B, V., the influence of the structure and phase composition on the wear resistance of sparing. Goal. Based on the above, the purpose of this work was to study the influence of structure and phase composition on the wear resistance of economically alloyed metastable and secondary hardening steels. Methodology. Surfacing of the studied materials was carried out in copper molds with different rates of forced cooling. Metastable austenitic, martensitic-austenitic and secondary hardening steels of the Cr-Mn-Ti system additionally alloyed with Mo, B, V were studied. Additional alloying of these steels with titanium in an amount of 2...5% contributed to the prevention of spalling along the fusion zone. Near the fusion line there is a base metal zone with a width of 7...15 µm. Results. After testing at the volume temperature of the working part of the specimen ТV=553…573 K in the contact volumes of the deposited metal of the 30Kh2V8F type, broadening of the grain boundaries, shear lines, finer grains compared to the underlying layers were revealed. Outside the zone of plastic deformation, the size of the grains corresponds to their sizes before the start of testing, the grain boundaries are relatively thin. The number and location of carbides observed at X430, X80O magnifications are also similar to the structural characteristics of the deposited metal of the 30Kh2V8F type. Originality. At close values of the contact pressure in the friction pair, the time of formation of a crack of critical length increases with an increase in the effective surface energy γе (including the energy of plastic deformation). Thus, the crack resistance indices (CR, j-integral, δС) and, consequently, the wear resistance of maraging steels are higher than those of metastable and tool steels. Practical value. The crack resistance indices (CR, j-integral, δС) and, consequently, the wear resistance of maraging steels are higher than those of metastable and tool steels. Conclusions. The conducted studies confirm the possibility of the formation of a "white band" both in alloys with a high concentration of elements - austenitizers (Mn, C, Ni), and when alloyed with carbide-forming elements with a relatively low affinity for carbon (V, Mo).

The Physiopathologic Roles of Calcium Signaling in Podocytes
Authors: Tu Yu-Chi , Shu Hua-Pan , Sun Lu-Lu , Liao Qian-Qian , Feng Li , Ren Ming , Yao Li-Jun
Published: October 2023

Calcium (Ca2+) plays a critical role in podocyte function. The Ca2+-sensitive receptors on the cell surface can sense changes in Ca2+ concentration, and Ca2+ flow into podocytes, after activation of Ca2+ channels (such as transient receptor potential canonical (TRPC) channels and N-type calcium channels) by different stimuli. In addition, the type 2 ryanodine receptor (RyR2) and the voltage-dependent anion channel 1 (VDAC1) on mitochondrial store-operated calcium channels (SOCs) on the endoplasmic reticulum maintain the Ca2+ homeostasis of the organelle. Ca2+ signaling is transmitted through multiple downstream signaling pathways and participates in the morphogenesis, structural maintenance, and survival of podocytes. When Ca2+ is dysregulated, it leads to the occurrence and progression of various diseases, such as focal segmental glomerulosclerosis, diabetic kidney disease, lupus nephritis, transplant glomerulopathy, and hypertensive renal injury. Ca2+ signaling is a promising therapeutic target for podocyte-related diseases. This review first summarizes the role of Ca2+ sensing, Ca2+ channels, and different Ca2+-signaling pathways in the biological functions of podocytes, then, explores the status of Ca2+ signaling in different podocyte-related diseases and its advances as a therapeutic target.

Background: Ferroptosis is a form of iron-dependent regulated cell death, and prior work has highlighted the potential utility of ferroptosis-inducing agents as tools to treat heart failure (HF). To date, however, no detailed examinations of the prognostic utility of ferroptosis-related genes (FRGs) in HF have been conducted. Methods: We used established genomic identification of FRGs for total samples in the gene expression omnibus (GEO) database, screened for differentially expressed FRGs, performed protein-protein interaction analysis and functional analysis of HF immune microenvironment subtypes. Subsequently, we applied tools to calculate immune cell infiltration, compare immune cell, immune response genomic and HLA gene differences between subtypes, and perform candidate drug identification. Finally, preliminary in vivo validation of the screened central genes was performed in animal models. Results: FRGs were compared between samples from HF and healthy control donors, revealing 62 of these genes to be differentially expressed as a function of HF status. HF patient-derived tissues exhibited significant changes in the expression of HLA genes, increase immune cell infiltration, and higher levels of other immune-related genes within the associated immune microenvironment. These FRGs were then leveraged to establish two different immune-related subtypes of HF based on clustering analysis results, after which these subtypes were characterized in further detail. Functional enrichment analyses revealed the identified differentially expressed genes to be enriched in key immune-related pathways including the primary immunodeficiency, natural killer cell-mediated cytotoxicity, FcϵRI signaling, and antigen processing and presentation pathways. The impact of the immune microenvironment was also explored through functional analyses, core gene analyses, and efforts to identify potential drug candidates for HF patients. Moreover, four key hub genes were identified as promising targets for therapeutic intervention in HF, including HDAC1, LNPEP, PSMA1, and PSMA6. Subsequent preclinical work in a mouse model system supported a potential role for HDAC1 as an important biomarker associated with the incidence of HF. Conclusions: To sum up, these results emphasize the importance of ferroptosis as a regulator of the HF-related immune microenvironment, highlighting viable avenues for the further study of molecular targets amenable to pharmacological intervention with the aim of treating this debilitating disease.

Background: Ovarian cancer (OC) is one of the most lethal gynecological malignant neoplasms. The aim of this study was to use high-throughput sequencing data to investigate the molecular and clinical characteristics of OC subtypes related to lipid metabolism and glycolysis, thus providing a theoretical basis for clinical decision-making. Methods: Molecular data and clinicopathological characteristics of OC patients were extracted from the Cancer Genome Atlas (TCGA), Genotype-Tissue Expression Project (GTEx), and the Gene Expression Omnibus (GEO). Following analysis of genes involved in lipid metabolism and glycolysis, OC was classified into subtypes by unsupervised clustering. The molecular features and clinical outcomes of these subtypes were then evaluated. Results: OC patients were divided into five subtypes based on the analysis of nine genes of interest. Amongst these, patients in subtype D had longer overall survival and more benign clinical features. Subtypes B and E had shorter overall- and progression-free survival, respectively. Both the B and E subtypes were closely related to lipid metabolism and to the glycolytic process. Subtype D was positively correlated with the infiltration of CD8+ T cells, CD4+ T cells, and macrophages, all of which play essential anti-tumor roles. Several risk models for selected subtypes were also constructed based on the expression of select genes. Conclusions: The present work revealed that irregular metabolism in OC tissues was an indicator of poor clinical outcome and altered homeostasis in cancer-related pathways. Moreover, aberrant gene expression signatures associated with lipid metabolism and glycolysis were also correlated with an immunosuppressive tumor microenvironment. Based on lipid metabolism and glycolysis, we have therefore identified several OC molecular subtypes that may prove useful for the development of potential therapeutic targets.
"Molla Nasreddin" ve Türkiye Mizah Basınında Kullanılan Ortak Türler
Authors: BABAYEVA Gulbeniz
Published: October 2023

Makalede, büyük gelişim süreci geçiren mizahın Avrupa ve Doğu halklarının edebiyat ve basınındaki yeri, tarihsel gelişim aşamaları ve gelişim süreci tutarlı bir şekilde takip edilmektedir. Yeni nitelikler edinen Türk hicivinin özel bireysel özellikleri 19.-20. yüzyıllarda ortaya çıkarılır, dünya hicvinin ilerici geleneklerinden ve ilginç örneklerinden yararlandığı gerçeğine değinilir. Türk, Arap ve Fars halklarının mizah edebiyatında fabl, fıkra, hiciv, kaside, kıta, rubai, nazire vs. ortak türler vardır. Bir sonraki aşamada mizahın sınırları - felyeton, mizahlı nesir örnekleri, komedi, satirik hikâye, uzun hikâye, roman, vodvil, manzum şiir vb. türlerin katkısıyla daha da genişler ve zenginleşir. Çalışmada, tüm bu ortak türlerin hem Azerbaycan hem de Türkiye`de yayımlanan mizah basınında kullanımı ortaya çıkarılır. Türkiye'de mizah basınının temelleri, "Molla Nasreddin" dergisinden 36 yıl önce çıkan “Diyojen” (1870) dergisi ile atılmıştır. Bu derginin yanı sıra daha sonra basılan “Hayal” (1873), “İstikbal” (1873), “Latife” (1873), “Çıngıraklı Tatar” (1873), “Kahkaha” (1874), “Geveze” (1875), “Çaylak” (1876-1877) gibi mizah gazete ve dergileri kuşkusuz ki “Molla Nasreddin” üzerinde etkili olmuştur. Aynı zamanda “Molla Nasreddin” dergisinin de Türkiye'de yayımlanan “Karagöz” (1908), “Nekregu” (1908), “Zuhuri” (1908), “Hacivat” (1908), “Geveze” (1908), “Kalem” (1908), “Boşbogaz ile Güllabi” (1908), “Dalkavuk” (1908), “Laklak” (1909) ve diğer mizah gazete ve dergilerin konu ve sorunlar üzerindeki güçlü etkisi, tür çeşitliliği ve karikatür geleneklerinin oluşumu olgular temelinde yorumlanır. Karşılıklı edebî bağlar sonucunda Celil Memmedguluzade, Mirza Alekber Sabir, Salman Mumtaz, Ali Nazmi, Namık Kemal, Ziya Paşa, Abdullah Cevdet ve diğer şair ve yazarlar birbirlerinin eserlerinden yararlanır, ortak türlere yönelerek, parodiler ve dolaylama (periphrasisler) ortaya çıkarırlar.

The interaction of cultures has been developingfor many years, and the outstanding sinologist Leonid Evseevich Cherkassky made his contribution to the familiarization and acceptance of Chinese culture by Russians. He presented to the Russian reader the works of a wide range of Chinese writers, from the Middle Ages to the 20th century. Many pages of his scientific and literary work are unknown, and new information should be open to the public. The author of the article, from the standpoint of historical objectivity, turns to the study of the translation of the last book of L. Cherkassky published in China, which in itself is a confirmation of his merits. The author reaffirms the conclusion about the indisputable significance of Cherkassky's work for strengthening Russian-Chinese literary ties and his notable contribution to the rethinking of Chinese culture by Russians.
