Published: October 2023

The issue of cognitive motivation of students is one of the key issues in pedagogy and teaching methods. The actualization of this issue is currently connected with the problems of modernization of education in Kazakhstan. One of these problems is caused by the search for funds for the development of cognitive abilities of students. The solution of this problem can be facilitated by the use of materials of everyday history in teaching history. This article is devoted to the educational potential of the history of everyday life, the direction of historical research that appeared relatively recently, in the last quarter of the twentieth century, and explores the life world of ordinary people – participants in the historical process. The relevance of the study of the possibilities of using the potential of everyday history in the process of teaching historical disciplines for the development of cognitive motivation of students and their socialization is due to the fact that this issue has been little studied in domestic methodological works. According to the authors of the article, it is impossible to get an objective picture of the past without taking into account all the wealth of historical knowledge, including the history of everyday life. Familiarity with the everyday behavior of people of other historical eras, with their mentality and system of moral values will show students the commonality and continuity of universal culture. The formation of a value attitude to one's past, its emotional perception determines the effectiveness of training. The article analyzes the educational tasks of the history of everyday life, considers the possibility of using innovative methods for teaching it. The authors believe that the formation of students' knowledge on the history of everyday life will contribute to a more adequate perception of the historical process, easier and more productive assimilation of educational material, increase the cognitive motivation of students, stimulate their socialization in society.

An analytical form of the model of the quasi-equilibrium conformational structure of the units of the Gaussian chain of a polyelectrolyte adsorbed on a nanospheroid witha relatively low electrical conductivity (undoped semiconductor) polarized in an external harmonically varying quasi-static electric field with a frequency significantly lower than the plasma frequency of the nanoparticle material is proposed. Variants ofthe model are discussed that go beyond the scope of the quasi-static approximation, i.e., take into account the effects of delay, the manifestation of which will be noticeable in the case of sufficiently extended nanostructures. Electrically induced conformational changes of generally neutral polyampholytic polypeptides on the surface of a spherical germanium nanoparticle in a static or alternating external electric field have been studied by molecular dynamics. In a static electric field, in the case of asmall distance between the charged units in the polyampholyte, a large number of macrochain loops were formed, elongated in the direction of the polarization axis of the nanoparticle. If the distance between the oppositely charged amino acid residues of the polypeptide exceeded the diameter of the nanoparticle, the charged units were mainly localized in the oppositely charged subpolar regions of the polarized germanium nanoparticle. In an alternating electric field, a girdle polyampholyte edge was formed in the equatorial region of the nanoparticle, the macrochain links of which were desorbed from the surface with an increase in the amplitude of the polarizing alternating electric field.

Published: October 2023

The realization of the possibilities of communication systems depends significantly on the quality indicators of the management system and its material basis - the communication system itself, especially during the full-scale invasion of Russia on the territory of our state. Currently, the readiness, probabilistic-temporal and operational-technical characteristics of control and communication systems are as important indicators as the number and quality of means of countering the enemy. In order to increase the effectiveness of the functioning of the mobile components of the special communication systems, it is planned to make extensive use of radio communication equipment and systems in their composition. This will allow solving the existing problems of continuity and stability of management already in the near future and opens further prospects for improving the operational and technical characteristics of the special communication system as a whole Orthogonal Frequency Division Multiplexing (OFDM) is widely used in the construction of radio communication systems. A lot of attention is paid to the construction of signal-code structures (SCC), which allow to increase the speed of information transmission with restrictions on energy and bandwidth of operating frequencies. The article proposes a technique that consists in building a signal-code structure with optimal parameters according to the criterion of maximum frequency efficiency while limiting the probability of false reception of signals in the conditions of nonlinear signal distortions in the radio path, which allows to increase the speed of information transmission with restrictions on energy and bandwidth operating frequencies (increase the frequency efficiency of the system). Increasing the frequency efficiency of SRS with OFDM by matching the form of the transmitted signals and the type of modulation with the parameters of the communication channel without additional expansion of the channel bandwidth and increasing the transmitter power is a rather urgent task.

Authors: Sapega V. A. , Tursumbekova G. Sh.
Published: October 2023

The research aims to comprehensively assess pea and soybean varieties based on their ranking by yield and adaptive parameters in the conditions of the northern forest-steppe zone of the Tyumen region for the years 2019-2021. The authors identified the significant environmental variability during the years of variety testing. The best pea variety in terms of average yield and average yield in contrasting conditions was Ostinato (33.8 and 36.9 c/ha, respectively), while for soybean, it was the Siberiada variety (13.2 and 11.9 c/ha, respectively). The realisation of yield potential was low for all varieties and did not exceed 75%. Pea varieties outperformed soybean varieties regarding 1000 grain weight and plant height. The vegetation period for soybean varieties was 25-30 days longer than for pea varieties. All sorts exhibited high resistance to lodging. Stress resistance was low for all types, especially peas, ranging from -11.8 for the Siberian variety to -20.0 c/ha for the Ostinato pea. Yield variability among varieties ranged from 33.4% (Ostinato pea variety) to 53.4% (SibNIISK-315 soybean variety). The regression coefficient for all pea and soybean varieties was equal to or close to one, from bi = 0.96 (Siberiachka soybean variety) to bi = 1.04 (Ostinato pea variety and Siberiada soybean variety), indicating their plasticity. Soybean varieties exceeded pea varieties in terms of homeostasis. The best for peas in this indicator was the Ostinato variety (Hоm = 5.06), and for soybeans, it was the Siberiada variety (Hоm = 2.06). The pea variety Ostinato (2.4) and the soybean variety Siberiada (0.8) demonstrated the highest overall adaptive ability. Based on the sum of rankings for yield and adaptability parameters, the best pea variety was Ostinato (sum of orders 11). For soybeans, it was the Siberiada variety (sum of rankings 11).

Published: October 2023

The search and identification of genes responsible for economically useful traits of cattle is relevant. Dairy productivity as a complex quantitative trait, is controlled by a large number of genes and their transcription factors taking into account the physiology of the animal. The dynamics of dairy productivity depends on a number of factors, since the secretory activity of the mammary gland is controlled by a complex of hormones, genes, transcription factors and enzymes. The studied gene Pit-1 (POU1F1) is an informative marker in determining milk and meat productivity. The genotype of an individual determines its productivity potential and the norm of reaction to environmental conditions. Genotypes of the studied gene are identified by polymerase chain reaction and restriction fragment length polymorphism (PCR-PDRP) analysis. When analyzing the data, the chi-square test is used to determine the genotype, allele frequencies and Hardy-Weinberg equilibrium. The object of research – DNA of blood of red steppe, simmental breeds of cattle of Pavlodar region of Kazakhstan. According to the results of amplification of Pit-1 gene fragment the PCR product with the size of 451 bp was obtained. According to the results of amplicon splitting the genotypes AA (451 bp), AB (451, 207, 244 bp) and BB (207, 244 bp) were obtained. In the considered farms of the region genotypes BB, AB prevail. In the studied groups of animals of the region high frequency of allele B is observed; in red steppe – 0.689, simmentals – 0.549; frequency of allele A – 0.312; 0.451 respectively. Genetic equilibrium is not disturbed; the criteria of reliability of the empirical distribution to the theoretical one in red steppe breed – 0.04, in simmentals – 0.16. The revealed associations of Pit-1 gene polymorphism can be used for selection and selecting parental pairs at directed breeding.

Published: October 2023

The effect of mutations in the FGF-5 gene on the wool productivity of sheep is considered. The conservation and rational use of the sheep gene pool is a very pressing problem for the development of sheep breeding in modern conditions. Thanks to the widespread use of methods for searching for genome-wide associations, the list of candidate genes for sheep productivity indicators is annually replenished. After identifying a new candidate gene, further work is aimed at a detailed study of its polymorphism and the search for mutations associated with gene expression and economically beneficial animal traits. A promising candidate for the quality indicators of sheep's wool is the hair growth regulator gene FGF-5 (fibroblast growth factor 5). FGF-5 plays a vital role in regulating the hair growth cycle during the development of mammalian hair follicles and skeletal muscle development. Haiyu Zhao et al. conducted a study of FGF-5 gene variation in the SG and SGG sheep populations, according to which ten putative SNPs were identified in the FGF-5 gene, and only five of them could be genotyped (SNPs 1-5). These SNPs are intronic mutations located in the first intron of the ovine FGF-5 gene. It was found that the frequencies of homozygous wild alleles at SNP1, SNP2, SNP3 and SNP5 were higher than those of the mutant alleles, except at the SNP4 locus. This study suggests that the presence of polymorphisms in the FGF-5 gene may affect hair growth in sheep and that hair growth may be enhanced by altering the expression of the FGF5 gene.
Enterohepatic circulation of bile acids and its role in pathologies of the hepatobiliary system
Authors: Kuznetsov Yu. E. , Lunegov A. M. , Ponamarev V. S. , Romashova E. B.
Published: October 2023

Enterohepatic circulation of bile acids is a highly regulated process of secretion of these compounds, intestinal reabsorption and reverse transport to the liver. Violation of this process has significant consequences for the homeostasis of the gastrointestinal tract, liver and the whole organism. This process is tightly controlled by regulatory enzymatic reactions with negative feedback, which leads to the maintenance of a pool and adequate homeostasis of bile acids. The main purpose of this article is to consider the mechanism of enterohepatic circulation of bile acids and evaluate their role both in the formation of pathologies of the hepatobiliary system of various origins, and as a predictor of such processes. We searched for original studies in the scientific databases PubMed, Elsevier Science (Scopus) and Clarivate Analytics (Web of Science) over the past 20 years to identify the features of the above processes, after which a formalized content analysis of the found publications was carried out. Theoretically, every factor that disrupts the enterohepatic circulation leads to pathologies of the hepatobiliary system. However, there are still many unknown aspects when it comes to the regulation of bile acid homeostasis in the enterohepatic circulation. In the last few decades, it is believed that the most important prerequisites for the occurrence of hepatopathy are hypersecretion of bile cholesterol and supersaturation of bile with it. An equally important problem is the change in the pool of bile acids, since its various representatives differ both in chemical activity and in the mechanism of action (from cytotoxicity to cytoprotection).

Published: October 2023

Tomato is one of the major vegetable crops valued for its high content of various vitamins, organic acids, antioxidants, essential macro- and microelements, and other substances necessary for maintaining normal body functions. Due to its characteristics, tomatoes are widely grown, but there are still "blank spots" in their production technology, especially in fertiliser application. This article presents the experience of using different rates of liquid (KAS-32) and solid (ammonium nitrate) mineral nitrogen fertilisers on the author's tomato varieties in open field conditions. The authors found a significant effect of nitrogen fertilisers on the duration of the main phases of the growing season and the entire period of tomato growth. Specifically, using ammonium nitrate for up to 15 days and KAS-32 for up to 17 days increases the vegetation period. Fertiliser application substantially improves crop structure and increases crop productivity. The difference compared to the control is over 150%, with the maximum effect achieved at increased doses of KAS-32. The maximum yield increase is 45 t/ha in variants with ammonium nitrate and up to 62 t/ha in variants with KAS-32. Under the influence of nitrogen fertiliser application, the content of dry matter increases by 15–20%, total sugar by 76%, and vitamin C by 38%. The most significant effect is achieved using KAS-32, where all quality indicators are 5–10% higher than ammonium nitrate.
Ruptured brainstem arteriovenous malformation associated with a thalamoperforating artery aneurysm arising from the P1 segment of the right posterior cerebral artery: illustrative case

Published: October 2023

BACKGROUND

Cerebral aneurysms of perforating arteries are rare and can be difficult to detect on computed tomography angiography (CTA) and digital subtraction angiography. Treatment is challenging and associated with a significant risk of morbidity. Endovascular treatment of a thalamoperforating artery (TPA) aneurysm within the midbrain has not previously been reported.

OBSERVATIONS

A 13-year-old girl with no previous medical history presented with unconsciousness and anisocoria. Head computed tomography showed a right midbrain hemorrhage. CTA showed a midbrain arteriovenous malformation fed by a TPA aneurysm arising from the P1 segment of the right posterior cerebral artery. The feeder had a small distal aneurysm, which increased in size over time. Endovascular embolization was then performed.

LESSONS

Cerebral aneurysms of perforating arteries are rare and can be difficult to treat. This is the first report of the endovascular treatment of a TPA aneurysm within the midbrain. Understanding the individual patient’s brainstem perforator anatomy and the associated blood flow is essential before occluding a TPA aneurysm to avoid causing ischemia or infarction. Arteriovenous malformation embolization within the brainstem should be avoided because of interperforator anastomoses.
Microsurgical resection of a ruptured intraventricular arteriovenous malformation in a neonate: considerations in management. Illustrative case
Authors: Stone Lauren , Colliander Reid , LoPresti Melissa A , Shaibani Ali , Lam Sandi
Published: October 2023

BACKGROUND

Arteriovenous malformations (AVMs) are the most common cause of intracranial hemorrhage in children, although they are rarer in neonates. Age, location, lesion architecture, and rupture status define treatment options. Sparse literature exists to guide the management of clinically symptomatic intraventricular AVM rupture in neonates. We highlight the case of a neonate with a ruptured intraventricular AVM to showcase considerations in treatment, discuss surgical technique, and help guide management.

OBSERVATIONS

An 18-day-old female presented with lethargy in extremis and was found to have new intraventricular hemorrhage. Angiogram revealed a Spetzler-Martin grade 2 AVM with a right posterior choroidal feeder and deep venous drainage within the ventricle. Her age limited radiosurgical and endovascular interventions. She underwent an interhemispheric, transcollosal, intraventricular approach for complete AVM resection. Perioperative care was managed by a multidisciplinary team, successfully mitigating the patient’s high risk of hemovascular collapse.

LESSONS

Stereotactic radiosurgery, endovascular embolization, and microsurgery are options for AVM obliteration, and multimodal therapy must be tailored to the lesion and patient. Conservative management can also be considered. Each intervention carries risks and varying likelihoods of success. Balancing these outcomes is challenging without definitive, high-quality, evidence-based guidance. The best treatment maximizes the chance of AVM obliteration while minimizing morbidity.
The John Wesley Powell Fossil Track Block—theropod tracks with ornithopod-like morphology from the Early Jurassic Navajo Sandstone, Glen Canyon National Recreation Area, Utah-Arizona

Published: October 2023

A large fallen block of Early Jurassic Navajo Sandstone located at Lake Powell, within Glen Canyon National Recreation Area, south-central Utah, displays natural casts of vertebrate tracks. The footprints occur on at least three track-bearing horizons preserved on and between stromatolitic sandstone beds. Two large, parallel trackways, plus a third, divergent trackway, on the main track layer (MTL) superficially resemble ornithopod footprints; however, they were produced by large-sized theropod dinosaurs, ratherthan ornithischians, and we identify these as Eubrontes. Small coelophysoid theropod tracks (Grallator) are the most common vertebrate ichnofossils on all track-bearing horizons, with approximately 50 footprints preserved on the MTL, six on the highest surface, and three on thinner float slabs stratigraphically lower in section. An additional 12 tracks in three trackways of Anchisauripus size occur on the MTL, but they superficially resemble Kayentapus in having wider divarication angles than typical Anchisauripus. The MTL also preserves at least five closely associated tetradactyl footprints that we identify as cf. Brasilichnium. A nearby, smaller fallen block preserves distinct Batrachopus tracks, which are rare in eolian environments. The microbial (possibly endoevaporitic) mats and stromatolitic horizons on which the animals had walked produced a distinct ichnomorphologic variation because of substrate consistency and the elastic properties of the mats, resulting in differential compaction of the bedding surfaces. Lithic compaction of the finer-grained sediments between denser, more resistant sandstone beds pre- and/or post-lithification resulted in additional deformation of the tracks, followed by natural erosion. We interpret these natural cast footprints on the MTL as possible transmitted tracks. The track-bearing, microbial-mat surfaces represent interdunal pooling of water, probably during periods of increased precipitation and/or rising water tables during wet seasons.

Published: October 2023

Over the last nine years, a forty-seven-person digital humanities project has explored the feasibility of computer assisted paleography for Syriac. That is, could one use big data, visual analytics, and recent advances in the digital analysis of handwriting to better understand Syriac manuscripts and Syriac manuscript culture? Last June we launched the public-facing part of our project titled the “Digital Analysis of Syriac Handwriting” or DASH (dash.Stanford.edu). DASH consists of digital page images from 90% of the world’s surviving Syriac manuscripts securely dated to before the twelfth century, as well as 90,000 individually trimmed letters from these manuscripts. In addition to introducing this tool to scholars of Syriac, this article presents a series of novel visualization tools that can also serve as a starting point for digital paleography projects in other linguistic traditions.

Authors: Mcconaughy Daniel L.
Published: October 2023

This paper extends Andreas Juckel’s important 2009 article, “Research on the Old Syriac Heritage of the Peshitta Gospels: A Collation of MS Bibl. Nationale Syr. 30” (Hugoye 12.1, 41-115). The research herein is based on collating the text of Acts contained in this noteworthy Syriac Biblical manuscript against the standard Peshitta text and forty-two other Peshitta manuscripts and more than one hundred fifty Syriac patristic sources. The collations show that the text of Acts in BNS30 has approximately 230 non-orthographic variant readings, of which 117 are unique variants not found in other Peshitta, Harklean or Christian Palestinian Aramaic MSS of Acts. There are approximately 51 agreements with the Harklean version. This paper shows that the statistical textual profile of Acts in MS Bibl. Nationale Syr. 30 is consistent with Juckel’s findings regarding the Gospel text of this manuscript. It also provides analyses of selected readings and a complete collation of the manuscript.

Amidst mounting concerns regarding the health and environmental repercussions associated with synthetic agents, there has been a burgeoning interest in the exploration of natural dyes as a safer alternative. Derived from minerals, plants, and animals, these natural dyes have gained substantial traction due to their perceived eco-friendliness and reduced health risks compared to their synthetic counterparts. Notably, our study revealed significant enhancements in fastness properties across all mordanted samples, while those left un-mordanted exhibited notably inferior fastness properties. Among the mordants under investigation, potassium aluminium sulphate demonstrated appreciable stability characteristics, yet Citrus limon extract emerged as an even more effective mordant than potassium aluminium sulphate. The study also delved into evaluating the colour strength properties of the test samples, providing a comprehensive analysis of the Tencel fabric's overall dye performance and adherence to industry standards. In this research, a natural dye was extracted from the leaves of Azadirachta indica which was applied to Tencel fabric, which was then meta-mordanted with potassium aluminium sulfate and Citrus limon extract. The study explored various dyeing parameters, including diverse dye concentrations (7 g), dyeing temperatures (35, 50, and 65 °C) with a precision of ±1 °C, and dyeing durations (40, 55, and 75 minutes). The resulting samples were then subjected to testing against fastness properties, including washing fastness (ISO 106 C06), rubbing fastness (AATCC 8), perspiration fastness (ISO 105 E04) and Colour strength (K/S) of the Tencel fabric. The assessment of fastness properties was carried out using a grey scale.

Published: October 2023

This study aims to determine the metaphor’s development and scientists opinion about its existence in Arabic and Al Quran. Studying metaphor in rhetoric discourse is important because it is related to Al Quran's stylistic and metaphor is a part of it. It is undeniable that metaphor evolved from the beginning of its emergence. Furthermore, experts argued on the existence of metaphor. The type of this research was literature review. The data in this research were obtained from relevant references. The results indicate that metaphor is part of language use. The first person to use metaphor was Abu Ubaidah Muammar Al Mutsanna. This term was developed by Al Jurjani who classified metaphor into majaz lughawi and majaz aqliy.  Experts also argued on the existence of metaphor in Al Qur’an and Arabic. According to some of them, metaphor is not entirely included in the Qur’an.. Others claim that metaphor appears in the Qur'an and Arabic. Because the existence of metaphor is particularly significant in the meaning of language, the researcher choose the majority opinion that metaphor can be found in the Qur'an and Arabic.

In this work, we reported isotopic effect in H2@X12N12 and H2O@X12N12 (X = B and Al) molecules at LC-ωPBE/6-311 G(d,p) level of theory. Zero-point energies values (ZPEs) of H2, H2O, H2@X12N12 and H2O@X12N12 molecules were calculated. Isotopes influenced the excess energies attained by molecules due to compression. The changes in ZPE of H2@X12N12 and H2O@X12N12 and those isotopic molecules intensely surpass those of the H2 and H2O molecules, subsequent in the great deuterium and tritium isotope effects. The excess of compression energy ( Δ ɛ) obtained by the molecule under compression was sensibly, about 5.00–2.60 (X = B) and 1.48–2.63 (X = Al) kcal/mol. Larger kH/kD and kH/kT values were found in the presence of X = B than X = Al. These outcomes were recommended as a probe for analysis molecular compression of enzymatic positions; they may be significant for exploring extremely great experimental isotope effects in various enzymatic reactions, where they were ascribed to the tunneling.

This study presents a space vector pulse width modulation (PWM) method for a multilevel single-phase decentralized power converter (DPC) called MSPDPC. The proposed model is built by connecting half-bridge cells in series. The output voltage can be adjusted according to demand by adding or subtracting cells. Cells use communication protocols to transmit and receive information with two neighboring cells. The received data contains information for the decentralized space vector pulse width modulation (DSVPWM) method proposed in this paper. In the proposed DSVPWM method, cells set up links to exchange information such as cell position, total cells in a phase, reference voltage amplitude, and reference frequency. The PWM control signals of each cell are calculated based on the information received. The study also focuses on evaluating the ability to adjust the switching vector and the corresponding dwell time of the cells when the structure of the DPC changes. The ability to dynamically reconfigure the DPC is a crucial feature that ensures uninterrupted power supply in case of one or several cell failures. The system automatically establishes a new state with the active cells. The proposed configuration and communication method between cells provide very fast configuration times. The load voltage of the DPC is adjusted to 0.5 times the voltage per cell, which allows the modulation voltage amplitude to be adjusted best according to the load requirements. The study used Matlab/Simulink software to review the initial assessments. The proposed model and algorithms will be verified on the Digital Signal Processor (DSP) platform with a 220V/500W load.

In this paper, a passivity – based control of a DC-DC boost power converter using genetic algorithm is proposed. The output of a DC-DC power boost converter is an inductor current. Its input is duty ratio . Using a co-ordinate transformation of state variables and control input, a DC-DC boost power converter is showed to be passive. A new plant is zero-state observable and the equilibrium point at origin of this plant is asymptotically stable. Then, a passivity - based control law is applied to this plant so that a voltage of capacitor x2 is equal to a value of desired voltage Vd when changing control input, duty ratio . The parameters of the passivity – based controller are also adjusted optimally by genetic algorithm using decimal encoder. Simulation results of a passivity – based control are good when the input voltage E, the load resistor R and the desired voltage Vd are varied. With variations of desired voltage Vd, the passivity – based controller supplies small value of IAE (integral absolute error of Vd and x2), small error, and short settling time Finally, simulation results show that the passivity – based control using genetic algorithm is better than the passivity – based control.

The primary purpose of this paper is to investigate the level of IT decisions accuracy between female and male directors on board. The research uses qualitative studies by interviewing four directors (two females and two males) who are in charge of making IT investment decisions. Furthermore, the data analysis uses Leadership Theory, Decision Quality Theory and Analytic Hierarchical Process. Results show that gender plays a pivotal role in shaping board directors' conduct in an IT investment decision-making where male and female leaders have specific attributes that will contribute to a successful IT investment decision-making. Moreover, the results also can be used as a fundamental for enterprises to change their policy regarding gender equality in a workplace to create a more diverse working environment. This research becomes significant considering the number of females on IT and board remains limited for several years despite women emancipation being encouraged across many platforms.

Omarbekov was one of the first Kazakh scientists to turn to the study of the so-called «blank page» in the national history at the beginning of independence. On the basis of previously unknown 139А.М. Азмұханова Turkic Studies Journal 2 (2022) 130-140archival documents and new methodological approaches, he managed to convey to the general public the truth about the tragic events of the period of forced collectivization and anti-Soviet uprisings. The study of the causes and consequences of the great famine of 1932-1933 in the Kazakh steppe takes a special place among his scientific works.The next direction of scientific research of T. Omarbekov were the problems related to ancient and medieval history of Kazakhstan. He made a great contribution to the research of the history of the origin of the Kazakh people, the emergence and formation of its statehood. Thanks to the enormous efforts he made when he was at the head of the historical research center «Alash», the basic monographs «History of Kazakh clans and tribes», «Ethnic history of Kazakhs», «Kazakh statehood: the history of kaganates, ulus and khanates», «Kazakh khans» and others were published. T. Omarbekov devoted the last decade of his life to the study of the ethnic history of the Turkic peoples of the Great Steppe. He headed several research projects in this direction and later was the head of the Republican Center for the Study of Traditional Civilizations of Central Asia. As a result of the fruitful work of the team of the scientific institution headed by him, he managed to publish the monograph «History of the Civilization of the Nomads of Central Asia», a collection of essays «Questions of the History of Traditional Civilization in Central Asia», a four-volume textbook «History of Kazakhstan», as well as several teaching aids.T.

The article deals with the historical toponyms of the Great Silk Road, which is located in the territory of nowadays city of Shymkent. It is well known that in the naming of places folkloric 19Ж.Ә. Аймұхамбет, М.Н. Миразова, Қ.Қ. Кенжалин Turkic Studies Journal 2 (2022) 7-21material is also of great importance, which is imprinted in the richest resources of ethnic language and has a special literrary and educative value in the culture and life of each people. Therefore, the study of toponymy is relevant and in demand not only in linguistic terms but also in literary criticism, folklore and using historical materials and sources. In this article, the well-known historical places of Shymkent taken as the target of analysis, especially place names names as Koshkar ata, Suburgan ata, Dervish ata, Kambar ata, which we study in the context of anthropotoponymy. Anthropotoponymy, a branch of toponymy, deals with the names of objects and places determined by the name of a person, mythological figures, folk myths and legends. In this article, the above-mentioned toponyms associated with the names of historical figures, folk and mythological heroes, legends (many of which originate from oral folk art) will also be referred to as anthropotoponymic. Anthropotoponymic legends play an important role in people’s spiritual and cultural life, reveal people’s mentality, folkloric space and artistic consciousness.The authors of the article, based on motif comparisons of folklore texts, consider the hyperbolic reflection in anthropotoponymous legends of the names of individual places and stories of people whose outstanding merits have been preserved in the memory of the people; show the connection between the literary motifs of these legends and the worldview of the Kazakh people. Taking into account the fact that the term “literary onomastic” exists in foreign literary criticism, the authors show that the emergence of this term is due to the literary structure of the folk toponyms and the visual techniques used in them.As a result of the analysis of the legends about the toponyms taken as the target of study, the idea that the Great Silk Road played an important role not only in trade relations but also in the development of spiritual and cultural ties between peoples was substantiated

Examples of dog burial are often found in Kazakh archaeology. The history of identifying such symbolic burials of this animal goes back centuries. The burial of a dog at the gates of the city was revealed during a study of the medieval site (hill fort) of Koskuduk in the Shui Valley. There are no direct analogies to our burial of a dog at the gate; in contrast, dog use in funeral rites in many studies is limited to illustrations from some sites and covers a particular chronological period in the scientific literature. 43Акымбек Е.Ш., Шагирбаев М.С. Turkic Studies Journal 3 (2022) 17-43The purpose of the article: to give a comparative analysis of the funeral rite of the dog at the gates of the medieval settlement of Koskuduk in the context of the funeral rites of Kazakhstan and neighboring regions. Increasing respect for the dog among the Turkic peoples can be traced in oral tradition, folklore with dog images, in proverbs and sayings, in phrases and idioms, in the observance of rituals.In the process of research, we found that finding a dog in funeral rites originates from the Stone Age, undergoes a number of changes in the Middle Ages and has continuity in modern rites of Turkic peoples.Based on the data obtained as a result of the study, an analysis of similar rituals available in modern Kazakh ethnography, the authors of the article note that the inner meaning of the burial of a dog at the gates of the medieval hill fort of Koskuduk may have been «farewell to the old habitat» and the burial of a dog in complexes means – the embodiment of the image of the «eternal watchman».
