Published: October 2023

ABSTRACT

The majority of researchers have carried out simulations using computational fluid dynamics (CFD) and experimental investigation for design, manufacturing, performance evaluation, understanding flow behavior, efficiency prediction, condition optimization, etc. The main objective of the recent paper is to compare horizontally finned and 45° inclined finned solar air collector absorbers and to select the better construction using numerical simulation. ANSYS Fluent Workbench 2022 with renormalization-group (RNG) group k–ε turbulence model was applied for the analysis of the computational domain of solar air heaters. The simulation results generated using CFD were validated with data from the literature, and the simulation results were in agreement with experimental results from the relevant literature. Based on the simulation results the horizontal finned solar air collector absorber has better heat transfer behavior than the 45° inclined.

A Study of Demonstrative Determiners in Pashto
Authors: Imdad Ali  , Dr. Sikandr Ali  , Humera Sharif
Published: October 2023

The existence of determiner phrases and their different manifestations in number, gender, and case have been studied and proved in English in many research studies. Many languages other than English need this investigation to establish a sound hypothesis about the universal language structure. This study was an attempt to find out the structure of the determiner phrase in the Pashto. It also investigated the equivalents of the English determiner phrase in the Pashto. It used the spoken corpus of Pashto as primary data. In addition, short stories and novels written by literary writers in the Pashto have been used as secondary data. Moreover, intensive group discussion with native speakers of Pashto has also been utilized as another secondary data source. The minimalist program was used to guide and understand the syntactic structure of languages. It was followed by the determiner phrase hypothesis. The hypothesis states that a noun is headed by its determiner in a noun phrase. Data were analyzed within the framework of the determiner phrase hypothesis. The study shows that a noun in the determiner phrase is not determined by a definite or indefinite article in Pashto. The determiner phrase is inflected for number, gender, and case in Pashto. Furthermore, the Pashto determiner phrase is different from English in terms of medial demonstrative determiners. The study is significant as it provides insight into the structure of the Pashto determiner phrase.

In the article is investigates the electromagnetic field of a barrel-shaped hollow resonator. It is significant that in the articles of K.M. Tsibizov developed an approach for determining the fields of waveguide resonator devices with a variable cross section. In this article, this approach is extended to a barrel-shaped hollow resonator. The solution of the Airy equation, which was used by K.M. Tsibizov are approximate solutions obtained through solving an equation that reduces to one of the forms of the hypergeometric equation or the Weber equation. The radial and azimuthal components of the field of a barrel-shaped hollow resonator are the corresponding components of the field of a hollow cylindrical resonator, and the longitudinal component is described by a degenerate hypergeometric function. In this article presents the design of a barrel-shaped waveguide resonator with metal ends and writes expressions for the resonant wavelengths of a barrel-shaped resonator with metal ends for H- and E-oscillations. The resonant wavelengths and resonant frequencies for two barrel-shaped resonators with metal ends are given in accordance with a cylindrical resonator with an equal end radius of the barrel-shaped resonator and equal longitudinal dimensions. The article also presents a waveguide resonator with an open left end and writes down the first five roots of the Airy functions. The consideration of such a resonator aims at demonstrating the generality of the considered approach.The design of a barrel-shaped resonator with open ends, the sections of which are critical, is presented.It is indicated that finding solutions to the equations of functions that describe the longitudinal distribution of the field is a demonstration of the generalization of the approach developed by K.M. Tsibizov, and as examples of the study of resonators of variable cross section: a barrel-shaped waveguide resonator with metal ends, a waveguide resonator with an open left end, and a barrel-shaped resonator with open ends, which are shown in the figures.

Methods of increasing the effectiveness of threat detection in distributed databases using the event monitoring system are considered in the work. It is noted that the system works on the basis of the event monitoring model of heterogeneous distributed databases. This model involves three stages of event processing, which are based on appropriate methods. It is highlighted that the mechanisms underlying the functioning of the mentioned methods should be reduced to a single data format to eliminate the possible appearance of incorrect work in future calculations. The event processing method on the monitoring server allows for processing event matrices and transferring the function to control tools, on the basis of which appropriate decisions are made to improve reliability. The article develops a modified method of analyzing and monitoring events in non-relational distributed databases. Event monitoring options for lookup operations in distributed databases are offered. To confirm the theoretical results, mathematical modeling and experimental research on monitoring parameters and data processing speed on the event monitoring server were carried out. The number of detected incidents and the number of incorrectly identified events were studied, which in turn allowed for the protection of information from unauthorized actions or changes. Also, it should be emphasized that the model proposed in the work describes detailed monitoring of requests, transactions, and stored procedures in a database with information about possible incidents in real time and prompts intrusion warnings. In addition, the features of the proposed model make it possible to investigate and monitor the emergence of new vulnerable segments of the database and promptly respond to them, eliminating threats to access channels. The paper compares the speed of data processing based on files and database tables, which allows for fully performing experiments and confirming analytical data experimentally.

A large number of scientific works are devoted to the problems of propagation of waves of different physical nature in periodic and heterogeneous media. The main problem considered in the article was the study of the shear wave in the layered-periodic structure "piezoelectric - gap". The statement is given and the problem of the propagation of volumetric acoustoelectric elastic shear waves in a regularly layered piezoelectric-slit medium is solved. Dispersion relations were obtained, which allow to investigate the possibility of propagation of wave fields with an arbitrary geometry of the period of the structure. A comparison of the spectra of the dispersion curves for volumetric acoustoelectric waves in a regularly layered space was carried out. The obtained dispersion relations were also analyzed numerically, and the results are presented in the form of graphs. Graphs of the limits of the boundaries of the transmission zones for various types of geometry of the generating layer package are given. As a result of numerical experiments, the possibility of the existence of transmission zones for bulk acoustic-electric waves in regularly layered media of the "piezoelectric - slot" type was established.
El Síndrome de Guillain-Barré en Perú: ¿Dengue y Zika detrás del aumento de casos?
Authors: Aguilar-Gamboa Franklin Rómulo
Published: October 2023

In 2023, Peru experienced the largest dengue outbreak in its history, with over 197,000 confirmed cases. Between epidemiological weeks 23 and 27 of that year, there was a peak in cases of Guillain-Barré syndrome (GBS), just two weeks after the peak of dengue cases. There is previous evidence associating dengue with the development of GBS, suggestingthat the dengue virus may be responsible for many of the current cases. Additionally, there were 31 cases of Zika recorded in Peru in 2023, a neurotropic virus that has also been previously linked to GBS. While there has been speculation in some media about the current GBS outbreak being related to Campylobacter jejuni in chickens, there is no conclusive evidence supporting this claim. It is necessary to conduct in-depth investigations into the presence of dengue and Zika in samples from patients with GBS to understand the potential causal role of these viruses. Studying the relationship between these infectious agents and the development of GBS can enhance prevention and treatment strategies for future epidemiological threats.

Objectives: There are a few studies on how much and which cognitive function is specifically damaged by chronic alcohol drinking. By comparing neurocognitive function test results between patients with alcohol use disorder and those with Alzheimer’s disease, we aimed to find out which neurocognitive function is damaged by chronic alcohol drinking. In addition, we investigated whether the structural changes in the brain were related to cognitive function decline.
Methods: Korean Wechsler Adult Intelligence Scale-IV and Seoul Neuropsychological Screening Battery-II were performed among patients who were diagnosed with Alzheimer’s disease and those who were diagnosed with alcohol use disorder at the department of psychiatry in Pusan National University Yangsan Hospital from November 2008 to May 2022. Among the neurocognitive domains, intelligence quotient, memory quotient, executive intelligence quotient, auditory attention and visual attention were compared. Among those who underwent cognitive function tests, the reading results for brain CT or MRI were compared.
Results: There was no significant difference between the two groups in visual attention (p=0.219). Meanwhile, structural changes in the brain were less in the alcohol use disorder group compared to the Alzheimer’s disease group.
Conclusion: Chronic drinking, impaired especially, visual attention to the level of Alzheimer’s disease at a relatively early age. Additional research on cognitive function impairment in alcohol use disorders is needed, referring to the results of this study.

This research type is a causality with the aim of analyzing the effect of corporate social responsibility on stock returns with profitability as a moderating variable on the LQ-45 stock index during the 2013-2017 period. The research population is all companies listed in the LQ-45 Index on the Indonesia stock exchange during 2013-2017. The sampling using a purposive sampling method with a total sample of 23 companies. Data of this research is quantitative type, with data analysis techniques consisting of descriptive analysis, testing classic assumptions, moderating regression analysis, and testing hypotheses. The results showed that there was a significant positive effect on testing the effect of corporate social responsibility on stock returns. High or low profitability (return on equity) is considered unable to moderate the influence of corporate social responsibility on stock returns because the large expenditure incurred for corporate social responsibility can have a negative impact on business operations that will reduce the level of profitability obtained by the investor.
INCREASING CULTURAL CAPITAL THROUGH THE ACT OF DEMONSTRATIVE CONSUMPTION OF WORKS OF ART
Authors:   Lugansk State Academy of Culture and Arts named after M. Matusovsky, Shatilov V.V.
Published: October 2023

The postmodern reinterpretation of values led to the blurring of boundaries between social groups and the diffusion between mass and elitist art. As a result, there was a need to form a new cultural threshold, which was fulfilled by symbolic capital. For a long time, contemporary art could not compete in prices with the works of old masters. However, since the early 2000s, there has been a trend of a rapid increase in prices for contemporary art. This article attempts to analyze this phenomenon, where a work of contemporary art is viewed as a "source" of symbolic capital, and the act of purchase is considered a form of conspicuous consumption, i.e., it is done not for the purpose of enrichment, but for the acquisition of authority and social status. The article proposes the assumption that in the current socio-cultural situation, an increase in symbolic capital can be achieved through the consumption of art. In the space of the modern art market, the artistic value of a work of art and, therefore, the volume of symbolic capital, are inversely proportional to its "accessibility", and the category of artistic value can be substituted with the economic category of price. In addition, the role of the art market in shaping new forms of art is traced. Contemporary artists, like their colleagues in the 1960s, continue to resist the art market. If this protest is fundamentally valuable, it leads to the emergence of new conceptual art practices, such as performance, land art, happening, etc.

Published: October 2023

The presented article is devoted to the problems of distance learning in the target areas. The article discusses in detail the problems of university distance education. By distance learning in this article, we will understand learning with the help of information technology. Distance learning is defined differently by different authors. With such training, the teacher perceives the students as an impersonal mass and has no way to assess the degree of understanding of the proposed material. The main purpose of the study was to consider distance learning for students who entered the university in the target areas of various divisions of the Russian Railway. The authors of the article consider the problems of distance learning of students in target areas at the Samara State University of Railways on the example of teaching higher mathematics. One of the methods of organizing targeted university distance learning is proposed, the project method. With the help of the project method, we propose to solve professionally oriented tasks when teaching students in the target areas in the course of higher mathematics. It is this format of education that is most promising. The approbation of this approach to teaching target students in a distance format has shown the effectiveness of the proposed teaching method.

Published: October 2023

The article looks at topical issues of vocational training specialists with secondary vocational education, whose qualification will allow to qualitatively replanish the personnel of textile industry enterprises. Secondary vocational education is undergoing an active modernization in our country. New technologies for training specialists of this level are aimed at improving the quality of education and developing a strategy that makes working professions prestigeous. Currently, there is a shortage of specialists with secondary vocational education, whose qualifications meet the modern requirements of the labor market. Many graduates of secondary vocational educational colleges cannot find a job in their specialty for a number of reasons, one of which is the discrepancy between the received education and the requirements of the labor market. This problem is being solved at the federal level through the implementation of the «Professionalitet» project, which means updating the system of secondary vocational education for training personnel in accordance with the real needs of specific employers from technical industries. The purpose of this article is to identify current problems in the system of training industry specialists with secondary vocational education and prospects for the development of training system for textile industry on the basis of large scientific-educational and production centres in the conditions of an experiment on the development, testing and implementation of a new educational technology for designing educational programs of secondary vocational education within the federal project «Professionalitet». As a result of the study, the main costraining factors were identified hindering the high-quality training specialists with secondary vocational education, as well as the key elements that are extremely necessary for the training of those ones meeting the modern and promising requirements of the industry labor market were identified. The novelty of the research is determined in the emperical sustantion of the importance of increasing role of an industry employer in the development and implementation of educational programs of secondary vocational education of a new generation. There is an obvious need to redistribute the functionality of the employer and the administration of a secondary vocational educational college when designing educational programs. An industry employer becomes the main developer of the educational program (its content and resource provision), while the administration of a secondary vocational educational college becomes a link providing consulting and methodological support.

Currently, students of higher educational institutions are constantly in a huge flow of information, not only coming from everyday studies, but also in the flow of information that accompanies everyone in the modern information world. That is why the teacher is required to show outstanding skills in order to contribute to the development of students' interest in acquiring new knowledge and learning in general at each lecture or practical lesson. It is possible to increase interest in the discipline being studied if you organize the acquisition of knowledge within the educational process in such a way that the emphasis is placed on obtaining the knowledge necessary for further professional activity. In the first and second years of technical universities, the discipline "Higher Mathematics" is the most difficult for students. At the same time, in technical universities, the need to study mathematics is indisputable. In this paper we will demonstrate that with the help of a mathematical apparatus, problems that fall within the circle of physical study of electrical engineering are solved. That is why we believe that students, starting from the first year, need to be explained that the knowledge gained in the study of general education subjects will be used not only in the development of special disciplines, but also in further professional activities
THE EASTERN PRACTICES AS ONE OF THE SOURCES OF N. DEMIDOV'S METHOD
Authors:   Russian State Institute of Performing Arts, Aleksandrova M.E.
Published: October 2023

The practice of Demidov's sketches is widely used in theatrical pedagogy today. N. V. Demidov had a medical education, studied Tibetan medicine and suggested K. S. Stanislavsky to use the psychophysics work technics in acting accumulated in yogic teaching. In his own method, N. V. Demidov was looking for ways to actively include irrational mechanisms of the psyche in the process of acting, which is the basic of the desired state of creative inspiration, which is a special state of consciousness and is actively studied by modern science. The author of the article analyzes the connections between Demidov's approach and some provisions of the spiritual and bodily teachings of the East, which are the basis of work with psychophysics and have been attracting the attention of theater teachers for many years. Working with consciousness is one of the main directions explored by Eastern teachings, and it was thanks to acquaintance with Tibetan medicine, yoga, N. V. Demidov managed to get close to the subtle, elusive layers of the psyche and provoke the nature of the artist to a unique, free, creative existence on stage. It is in the XXI century that the Demidov's approach becomes extremely popular.
DIFFERENTIATION OF THE PUBLIC BY THE LEVEL OF ORIENTATIONS TO STAGE ART
Authors:   Lugansk State Academy of Culture and Arts named after Mikhail Matusovsky, Grebenik E.N.
Published: October 2023

At the moment, an important feature of the existence of the theater as a socio-cultural institution is its functioning in market conditions. Performances become the subject of sale and purchase, and the hedonistic function of the theater is opposed by great competition: cinema, the Internet, social networks, entertainment shows and show programs. In this regard, in order to remain in the consumer market, the theater uses innovative technologies and experimental forms, which lead to the loss of the uniqueness of the theater and a decrease in the level of the public. The effective implementation of the ideological and educational functions of the theater is directly related to the level of training of the theatrical public. The questions of his typology, the classification of the level of art education, are decisive in the perception of the performance. The genre orientation and subject orientation of theaters certainly depend on the ability of the public to perceive works of theatrical art. The article deals with the analysis of sociological studies of the interaction of the individual with art, as well as the study of sociocultural processes that form the orientation of the theater audience towards works of theatrical art. The author of the article pays special attention to the leisure activities of individuals and the formed stereotypes of the theatrical audience. The author also carried out an analysis of the cultural and leisure behavior of the public and derived the differentiation of the public according to the level of orientations and preferences for the performing arts.
PAINTER VASILY NEFYODOV IN THE BIOGRAPHY AND WORK OF SCULPTOR STEPAN ERZIA (NEFYODOV)
Authors:   National Research Ogarev Mordovia State University, Klyueva I.V.
Published: October 2023

The relevance of the topic is due to the need for a comprehensive study of the creative personality of an outstanding sculptor of the 20th century Stepan Dmitrievich Erzya (Nefyodov, 1876–1959). Object of the article: biography and creative (including art-pedagogical) activities of sculptor S.D. Erzia; subject of the article: creative, mentoring relationship of the sculptor with his nephew, the painter Vasily Ivanovich Nefyodov (1890–1918). The study is of a historical and cultural nature; it uses comparative-historical and biographical methods. The sources of the study are the works of S.D. Erzia and V.I. Nefyodov (both located in museums and archives of the Russian Federation, including the Republic of Mordovia, and not preserved, known only from photo reproductions), press materials of the first third of the 20th century, archival documents. The author reconstructs the biography of V.I. Nefyodov, reveals the role of S.D. Erzia in his creative development. As a result of the study, it has been proved that a number of surviving paintings, which are considered by researchers as the works of S.D. Erzia, actually had been created by his nephew. The author attributes the photo of V.I. Nefyodov, made in the suburbs of Paris Seaux in 1912, sculptural portraits of V.I. Nefyodov created by S.D. Erzia and other works dedicated to him. It is proved that the unpreserved statue “Prayer for a Chalice” made in the Urals, which some researchers (for example, the Ural archivist E.V. Shimonek) call “an unknown creation of Erzia”, is a grave monument for V.I. Nefyodov, made exactly from this photo.

Authors: Krotova A. L. , Makavchik S. A. , Sukhinin A. A.
Published: October 2023

Background. Veterinary monitoring of antibiotic resistance in pathogens of zoonotic diseases is necessary for the rational use of antibiotics. Integration and use of the AMRcloud online platform in veterinary institutions will significantly simplify data processing, increase the speed of data analysis of monitoring results, and help overcome the interagency barrier in the exchange of information between human medicine and veterinary medicine.

The aim of the study is the practical ap- plication of the AMRcloud online platform for veterinary monitoring of antibiotic resistance in pathogens of zoonotic origin.

Material and methods. In the course of veterinary monitoring, the susceptibility of 275 isolates (16 species of bacteria) to 13 antimicrobial drugs most commonly used in animal husbandry was determined. Among the antimicrobial drugs were: amoxiclav, ampicillin, benzylpenicillin, gentamicin, clindamycin, streptomycin, tetracycline, tobramycin, cephalexin cefotaxime, ceftriaxone, erythromycin, and colistin. The data obtained were combined into a single system using the AMRcloud online platform.

Results. The most common causative agents of mastitis were identified: Streptococcus agalactiae (n=96), Escherichia coli (n=55), Staphylococcus aureus (n=33) and Enterococcus faecalis (n=31). ESBL production have been detected in 13 (19.7%) of 66 isolates of the order Enterobacterales, isolated from clinical material of cattle and small ruminants, which limits the use of beta-lactam antibiotics for the treatment of mastitis.

Conclusion. The use of the AMRcloud online platform in veterinary laboratories greatly simplifies data processing, increases the result analysis speed, and provides an opportunity to exchange information on antibiotic resistance between laboratories.

Background: The prevalence of hypertension is rising globally due to unhealthy lifestyle. Smartphones are vitalinstrument as a result of the rising use of technology in education. Anxiety, sadness, and sleep difficulties are alllinked to smartphone addiction. These mental illnesses also have an impact on blood pressure. The purpose ofthis study was to investigate the prevalence of hypertension and its association with smartphone addiction amongadults.Methods: An university-based cross-sectional study was conducted on 74 young adults, aged 17-24 years(18.47±0.51for males and 19.27±0.97 for females) by random cluster sampling method after getting consent.Systolic and Diastolic blood pressure were measured according to normative data of ACSM guidelines. BMIwas calculated to identify the prevalence of obesity and its association with an increase in blood pressure. TheSmartphone Addiction Scale - a short version was used to assess level of smartphone addiction.Results: The prevalence of risk of developing hypertension in those who are having smartphone addiction was9.45% ((OR=0.53, 95% CI: 0.155-1.762). And the association between smartphone addiction and obesity was 6.75%.Conclusion: Among college-going students surveyed at KPGU University Vadodara, there is a risk of developinghypertension due to excessive smartphone addiction as it shows borderline or elevated blood pressure and obesity.This can affect their physical as well as mental health. Therefore it is essential to arrange educational seminars tomake students aware of reducing the use of social media by engaging them in various recreational activities.

Backround: Occupational Therapy is increasingly becoming popular. The objective of the present study is todevelop an insight to the current trends in practice of occupational therapy in India. The target group chosen forthe study are budding occupational therapists who have completed their graduation within the last 5 years.Objectives: The study aims to investigate the trends in location of work setups, nature of organization of work,nature of place of employment, current work profile, nature of cases these budding therapists are dealing withcurrently, the work setup they are employed in and remuneration they are receiving. The trends emerging from thepresent study would be helpful to understand the current work dynamics and thus prepare the young workforcefor future possible opportunities.Study Design: The present study was a survey-based research design. Data was gathered through a questionnaire.Methods: This questionnaire was distributed on an online platform to 695 therapists practicing across India. Carewas taken to include only the therapists who had completed their graduation within the last five years i.e., between2018-22. Data collection was carried out for a period of 8 months from October 2021 to May 2022.RESULTS: The analyses revealed that the profession of Occupational Therapy in the country is dominated byfemale therapists. The age of the workforce that have responded are in their mid-twenties. Most of them areworking in urban or metropolitan setups primarily in Paediatric setups in clinics which are mostly privatelyowned rehabilitation centres.Conclusion: The present analyses pointed out that there may be a lack of diversification of practice in OccupationalTherapy in the country. It also indicated that the freshly graduated out professionals feel that there are a limitedremuneration and lack of opportunities in the Government sector, and as a result the current scenario suggeststhat most of them after being trained turn their head to foreign land for a better opportunity with respect toemployment. However, new setups and areas of practice are slowly emerging and opportunities for youngbudding therapists are increasing back home.

Background: Overweight is a growing public health global epidemic that affects over 600 million people worldwideand leads to the development of multiple metabolic, mechanical, and mental health disorders associated withfatality. Binge eating disorder (BED) is a kind of eating entity associated with excessive weight. Nearly, 80%of those with BED have higher risk of psychopathology, including mood, anxiety, and sleep problems. Anxietyhas repeatedly been associated with overweight and eating disorders. So, the aim of this study was to find theprevalence rate of state trait anxiety and binge eating disorder in overweight individuals.Method: A self-administered questionnaire was prepared which consisted of survey related questions from StateTrait Anxiety Inventory and Binge Eating Scale. Total 51 individuals were selected on the basis of selection criteriaand the questionnaire was distributed amongst them. Data analysis using scientific calculation showed that therewas high prevalence rate of high level of state anxiety, moderate level of trait anxiety with moderate level of bingeeating in overweight individuals.Conclusion: The study supported the alternative hypothesis and indicated that there was

The need for maintaining the living environment is increasing as the economy grows and the quality of life rises. Attempting to render buildings "green" to the environment from the standpoint of civil engineering is a hot and challenging task now. The construction industry uses lightweight foamed concrete (LWFC) as a flexible building material. Contrarily, LWFC has a variety of flaws including stiffness, poor toughness, substantial porosity, crucial drying shrinkage, and minimal resistance to cracking and deformation. Although it’s a sustainable solution, continuous research strives to enhance its sustainability and mechanical capabilities. Nanoparticles have excellent mechanical, thermal, and electrical capabilities that have inspired the creation of new nanocomposites with exceptional and multipurpose features. Titanium dioxide nanoparticles (TNP) have a much larger specific surface area because of nanostructures' exceptional properties. The large increase in nanoparticles will boost the role of concrete strength by improving the microstructure of the material. There is significant uncertainty regarding the process by which TNP might change the strength characteristics of LFC because the influence of TNP in LWFC was not previously explored. To better understand how TNP affects the slump flow, compressive, splitting tensile, and bending LWFC of 980 kg/m3 density, this study will look at its effects. Six TNP weight fractions were taken into consideration: 0% (control), 1%, 2%, 3%, 4%, and 5%. Slump flow, electrical resistivity, compressive, splitting, tensile, and bending strengths were the variables investigated. In addition, the relationship between strength parameters was found. The results showed that the highest compressive, bending, and splitting tensile strengths resulted from a weight fraction of TNP of 3%.

Buckling analysis of thin-walled structures is essential to ensure their structural integrity under various loading conditions. The study aims to analyse buckling in thin-walled structures, particularly a C-section channel, under different loads, considering cases with and without holes, using FEM. It investigates hole impact on buckling, critical load, and mode shapes, offering insights for C-section channel design. A finite element method (FEM) is used to model the structure and simulate mechanical and thermal loading conditions. Additionally, the study investigates the critical buckling load factor and mode shapes for both cases with and without holes. The results show that the presence of holes significantly affects the buckling behaviour of the structure. The mode shapes indicate that the buckling behaviour of the structure is different for each case. The critical buckling load factor is lower for the C-section channel with holes, indicating a higher risk of buckling. The results of this study provide insights into the buckling behaviour of thin-walled structures and demonstrate the importance of considering the presence of holes in the design and optimization of C-section channels.

In recent years, there has been a notable rise in the utilization of augmented reality within educational settings. However, there is still room for improvement in early childhood education. This study aims to investigate how current augmented reality works in early childhood education between 2017 and 2022 using library research methodology. The study's content was analyzed based on the case studies on integrating augmented reality in early school education between 2017 and 2022. 26 studies were found when the keyword "Augmented Reality in early school" was used to start the study (in primary school). With a sample size of fewer than 21 kids, early literacy discovered that Science (Animals, Newton) was the most frequently used subject. Regarding data collection techniques, testing has emerged as the dominant technique in research of "marker-based" augmented reality on mobile devices. These findings help to clarify the best ways to use this technology in early learning settings. Over the past five years, the number of schools using augmented reality in early childhood education has steadily increased.
