DEVELOPMENT OF HUMANISTIC PROFESSIONAL QUALITIES OF THE TEACHER IN THE PROCESS OF INTERACTIVE EDUCATION OF YOUNGER SCHOOL STUDENTS
Authors: Komar Olha , Kilichenko Oksana
Published: November 2023

The article reveals the problem of developing the humanistic qualities of the teacher in the process of organizing interactive education in primary school. The professional and personal qualities which characterize a humane primary school teacher are defined. It is emphasized that special attention is paid to the organization of the educational process as effective multilateral communication. Applying one or another technology, in our case interactive, to solve the tasks of the educational process, the primary school teacher will definitely use appropriate teaching methods. That is, the implementation of training using certain technologies occurs primarily through a system of adequate methods, which are the core of this technology. The role of "active" and "passive" learning methods, when students act as the "object" of teachning, is analyzed. It is noted that interactive teaching methods provide the greatest space for self-realization of the student in learning and most closely correspond to a person-oriented approach. They are focused on the realization of the cognitive interests and needs of the individual, therefore special attention is paid to the organization of the process of effective multilateral communication, which is characterized by the absence of polarity and minimal concentration on the teacher's point of view. Participants of such communication are more mobile, open and active. Therefore, the key to understanding the role of interactive communication in the social development of a child, both a child and a teacher, is the thesis that a child's personality develops in unity, communication with the nearest micro-society, which includes peers and teachers. In addition, the use of interactive methods ensures the implementation of the idea of cooperation in the team, contributes to the improvement of the psychological climate in the classroom, and creates an atmosphere of goodwill during training. The study of the role of the organization of interactive learning in the development of humanistic qualities of primary school teachers was organized in the following directions: self-analysis of their personal and professional qualities and determination of the importance of interactive learning in the formation of humanistic qualities. It is noted that a special role in the development of the teacher's humanistic qualities in the process of organizing interactive learning is played by their readiness for professional activity
Visiones del extractivismo en Las tres mitades de Ino Moxo y otros brujos de la Amazonía de César Calvo
Authors: Di Benedetto Matías
Published: November 2023

Este artículo analiza las relaciones entre experimentalismo formal y la representación literaria de los efectos alucinógenos de la ayahuasca en Las tres mitades de Ino Moxo y otros brujos de la Amazonía de César Calvo. En este sentido, enfatizaremos en el tratamiento de dos materias primas fundamentales para los fines de las prácticas extractivistas en la Amazonía pero que en la obra de Calvo se resignifican. La ayahuasca funciona como principio constructivo de una lógica visionaria capaz de desconfigurar el abordaje histórico de los acontecimientos ligados a la explotación del caucho y, a la vez, como elemento clave de una crítica a los saberes y prácticas de la medicina occidental. La figura del curandero funciona en este sentido como un lugar de enunciación disruptivo ―y a la vez reivindicativo― de la cultura amazónica.
Jorge Santiago. El libro de los sacrificios. Lima: Pakarina ediciones, 2023, 100 pp.
Authors: Gensollen Sorado Juan
Published: November 2023

El libro de los sacrificios (Pakarina, 2023), de Jorge Santiago, se plantea como un conjunto de relatos signados por la violencia y el desencuentro, fundados la mayor de las veces en los linderos de la literatura fantástica y el género policial. Los cuentos transitan desde el suicidio, la delación, el homicidio, la extorsión y la extinción, hasta el reconocimiento, la sátira, el misterio, la ambición y la ficción fantasmal. Se trata de su tercera entrega cuentística. En la primera, Usted viene de allá (2012), Santiago explora diversos géneros, como el policial, el fantástico y el realista, incidiendo en el tema de la muerte y también en el de la venganza. Su segundo libro, Las dos caras del héroe (2018) reincide en los mismos géneros, aunque con menor presencia del registro realista, y en el que temas como la muerte y el destino inexorable parecen imponerse. En este tercer libro, el género realista es desplazado con mayor incidencia en lo fantástico, la ciencia ficción y lo policial, aunque el tema de la muerte y el de la venganza siguen estando presentes en varias narraciones.
La categoría tinkuy en Ximena de dos caminos, un caso de la narrativa contemporánea del centro del Perú
Authors: Damas Espinoza Gino Hernán
Published: November 2023

El presente tiene como propósito analizar la novela Ximena de dos caminos de Laura Riesco, a partir de doce dicotomías extraídas de su lectura: niño/adulto, campesino/minero, oralidad/escritura, animista/ irracional, nativo/extranjero, español/quechua, ciudad/campo, pasado/ presente, opresión/justicia, etc. El estudio consiste en la aplicación de la categoría andina del tinkuy (opuestos-complementarios) sobre los pares propuestos, a fin de demostrar la contradictoria realidad peruana, identificar los sentidos profundos de los mensajes, así como la sabiduría milenaria del hombre andino frente al mundo moderno. El principio de la dualidad es el eje central del pensamiento andino. Todo cuanto existe en el plano social y en el ámbito natural está interrelacionado. En la novela reconocemos pugnas individuales y colectivas, oposición entre dos universos: el andino y el occidental, el mundo de los adultos y el de los niños, el pasado y el presente, la opresión versus la justicia, etc. Estas contradicciones resumen nuestra historia y son los síntomas de la problemática socioeconómica aún no resuelta .
La poesía maya y zapoteca en perspectiva histórica
Authors: Gómez Gómez Felipe
Published: November 2023

Este artículo expone brevemente la configuración histórica de las actividades poéticas mayas y zapotecas, cuyos orígenes están ligados —en especial con los mayas— a los rezos y discursos ancestrales, recitados en actos ceremoniales y de curación de enfermedades del cuerpo y del espíritu. El análisis prioriza las figuras literarias presentes en los cantos y los elementos de la oralidad mezclados con el lenguaje cristiano, los cuales otorgan una secuencia rítmica particular, que no es lineal sino acumulativa, reiterativa y circular. Después se aborda el caso de los zapotecos, que tiene un panorama histórico más complejo, ya que se tiene muy pocos registros poéticos. Los más conocidos son los discursos que se pronunciaban en ceremonias de matrimonio, y un poema-canción muy breve. Sin embargo, con estos datos nos es posible establecer la conexión que tiene con los mitos, las prácticas culturales y la producción poética zapoteca contemporánea.

The results of studies of the influence of the MoO3 alloying additive, as well as HfO2 with different particle sizes on the phase composition and density of dysprosium hafnate pellets are presented. It is shown that the use of coarse HfO2 powder (ГФО-2 grade) with particles size from 1 to 100 µm does not lead to the achievement of high density of sintered pellets and the completeness of the dysprosium hafnate synthesis, since dysprosium oxide remains in the synthesized material at sintering temperature of 1650°C. The use of HfO2 manufactured by China Rare Metal Material with a crystallite size near 22 nm leads to anbugz increase in the sintered pellets density (8.2…8.3) g/cm3. The doping of MoO3 in the amount of 2.5 wt%. promotes the intensification of synthesis process with the formation of a single-phase fluorite structure at a temperature of 1450°C, but does not increase the density of sintered pellets.

Raman spectroscopy detects the vibrations of a molecule that scatters light inelastically (Raman scattering, with an occurrence of 1 in 108 scattered photons for this phenomenon to be generated). Its characteristics of high molecular specificity, semi-destructive nature, and ability to perform in situ analysis provide it with great versatility for the analysis of works of historical value [1]. It has been used successfully in the analysis of historical paints to identify pigments, dyes, and organometallic complexes [2, 3]. However, organic molecules often produce the fluorescence phenomenon that analytically overlaps the analyte signal due to the longer extinction time compared to Raman scattering [4, 5]. A technique developed to avoid the generation of the fluorescence phenomenon and the risk of carbonization or alteration of the sample during the analysis, is Surface-Enhanced Raman Spectroscopy (SERS)

Damage to the high-pressure rotor blade was due to a somewhat underestimated resistance of steel to brittle fracture, weakening of grain boundaries and interpacket boundaries by lamellar cementite particles, and overloading of the blades due to a significant number of rotor shutdowns. Under the influence of condensate formed during the operation of the rotor, all these factors contribute to the occurrence of corrosion damage to the leading edge of the blade. From these defects, cracks initiate and propagate by the mechanism of inter- and transgranular fracture, which is typical for high-cycle corrosion fatigue of such steels.

The susceptibility to stress-corrosion cracking of the pipe metal of a long-term operated for 40 years main gas pipeline made of X70 steel and an emergency reserve pipe during cathodic protection in NS4 was investigated. A tendency towards some increase in susceptibility to stress corrosion cracking at a potential shift of -0.75 to -1.05 V was found for the serviced pipe compared to stock pipe metal. It is shown that the value of KS is slightly higher for the operated pipe, which indicates the possible embrittlement of the steel with long-term exposure to external cathodic polarization.

Published: November 2023

The residual lifetime of a pipeline with an axial semi-elliptical crack on the outer surface was estimated. It was established that lifetime significantly decreases with an increase in the hydrogen concentrations in the metal of the pipeline. Similar tendencies are also visible with a change in the a/c relation (defect shape). That is, more elongated semi-elliptical cracks are more dangerous as compared to deeper defects. In general, of all the considered cases, the most dangerous is an elongated (a/c = 0.25) axial semi-elliptical crack on the outer surface of the pipe at a hydrogen concentration in the metal of the pipeline СH = 5.462 ppm.

Published: November 2023

The authors proposed a mathematical model for estimating the timespan life of an oil pipeline with a surface semi-elliptical microcrack under the turbulent flow of oil in a soil-corrosive environment, which leads to the degradation of the pipe material. A two-frequency load models the effect of the turbulent flow of oil on the pipe wall. The energy basis approach is helping to obtain a nonlinear differential equation with respect to the function of crack opening in the refracture zone with variable coefficients. The equation and the initial and final conditions of crack propagation constitute a mathematical model for determining the residual life of the pipe. The remaining service life of the oil pipeline made of X70 steel was estimated.

Published: November 2023

Objective The efficacy of previously developed respiratory barrier enclosures to limit healthcare workers’ exposure to aerosols from COVID-19 patients remains unclear; in addition, the design of these devices is unsuitable for transportation or other emergency procedures. Therefore, we developed a novel negative pressure respiratory isolator to improve protection from patient-generated aerosols and evaluated its protective effect in conversion to systemic isolator. Methods This in vitro study simulated droplets by nebulizing 1% glycerol + 99% ethanol solution. We performed cardiopulmonary resuscitation (CPR) and converted a respiratory barrier enclosure into a systemic isolator with a respiratory barrier as well as a respiratory barrier with negative pressure generator (NPG), which were compared with control and room air. During the procedure, particles were counted for 30 seconds and the count was repeated 10 times. Results During CPR, the total number of particles in the respiratory barrier with NPG (280,529; interquartile range [IQR], 205,263–359,195; P=0.970) was similar to that in the control (308,789; IQR, 175,056–473,276). Using NPG with a respiratory barrier reduced the number of particles to 27,524 (IQR, 26,703– 28,905; P=0.001). Particle number during conversion of the respiratory barrier into a systemic isolator was also lower than in the control (25,845; IQR, 19,391– 29,772; P=0.001). Conclusion The novel isolator was converted to a systemic isolator without air leakage. The aerosol-blocking effect of the isolator was quantified using a particle counter during CPR. Further studies comparing the barrier effect of isolators within various pressure differentials are warranted.

Published: November 2023

This study aimed to investigate the relationship between the imaginary of Caipora and environmental conservation in Serra da Jiboia. Data obtained through the application of semi-structured interviews and Likert scale. All data were analyzed qualitatively and quantitatively. Through factor analysis, it was possible to identify four factors that explain the variations in responses given by residents of the region, suggesting a strong belief in the spiritual entities of the forest and its importance for nature conservation. 57 interviews were carried out and the socioeconomic characterization of the participants was carried out, were composed of men and women predominantly between 50 years or more and who carry out agricultural activities. Although Catholicism is the predominant religion in the region, belief in Caipora was high, being related to the appreciation and preservation of local nature. Through the chi-square test, it was possible to verify a statistically significant relationship between the belief in Caipora and the activities carried out in the forest by the interviewees. This study contributes to the understanding of the relationship between popular beliefs and environmental conservation, highlighting the importance of considering local knowledge for the development of public policies aimed at nature preservation.

The role of Valentim de Carvalho in the emergence of the ‘Portuguese rock boom’ of the early 1980s
Authors: Andrade Ricardo
Published: November 2023

This article delves into the editorial processes that triggered the so-called ‘boom of Portuguese rock’ of the early 1980s, a term commonly used to denote the initial surge of commercial success for rock music created, recorded, and released in Portugal. I aim to spotlight the changes that shaped the development of rock music in Portugal at the turn of the 1970s to the 1980s, emphasizing the pivotal role of the record company Valentim de Carvalho in this period. During the late 1970s, shifts in the record publishing personnel significantly contributed to the primary upsurge in commercial success of records released by Portuguese rock bands and sung in Portuguese. The debut of Chico Fininho by Rui Veloso & A Banda Sonora and Cavalos de Corrida by UHF, both released by Valentim de Carvalho in 1980, were inaugural milestones of this success. By connecting this phenomenon with the various social and political transformations of that time, I explore the interplay between editors and musicians at Valentim de Carvalho, whose staff actively  engaged in shaping the musical endeavours of these groups and their repertoire.

Authors: Курянов В. М.
Published: November 2023

Актуальність корпоративної культури набуває все більшого значення в системі управління інноваційним розвитком підприємства в сучасному економічному середовищі, яке відзначається нестабільністю, турбулентністю, динамічністю та кризами, з одного боку, і зростаючим рівнем інформатизації суспільства, рівнем комунікацій у всіх сферах економіки з іншого. Фундаментальну роль у цьому відіграє загальний перехід до економіки знань, де домінує інформаційний ресурс, інтелектуальний капітал та нематеріальні активи. Розробка та створення міцної корпоративної культури є складним процесом, і не існує єдиної технології досягнення успіху. У статті розглядаються деякі зовнішні та внутрішні фактори, які впливають на формування корпоративної культури, та ризики для підприємств, які з цім пов’язані. На базі цього, було розроблено перелік рекомендацій для керівників підприємств готельно-ресторанної сфери, які зможуть покращити рівень корпоративної культури, продуктивність, психологічний клімат в колективі, зменшити рівень стресу та стурбованості, надати відчуття безпеки працівникам та підвищити довіру до керівництва.

Стаття присвячена дослідженню та систематизації тенденцій розвитку й обґрунтуванню напрямів інноваційної трансформації господарських суб’єктів агропромислового виробництва. Акцентовано, що глобальні тенденції та перспективні напрями розширення експортного потенціалу виявилась в агросфері у сировинній спрямованості виробництва і аграрного експорту, а існуюча агропропродовольча спеціалізація є вузькоасортиментною та сировинною. Обґрунтовано, що існуюче інституціональне середовище і наявна модель управління агросферою не забезпечили гнучкість та зміну формальних норм і правил взаємодії інноваційних суб’єктів економіки, не сприяли їх інноваційній активності. Виокремлені тенденції розвитку агропромислового виробництва в умовах постіндустріальних змін, що потребують виключної уваги і врахування та виділені й систематизовані еволюційні та інституціональні обмеження інноваційного процесу в агропромисловому виробництві.

Published: November 2023

Дана стаття присвячена дослідженню впливу російсько-української війни на процеси в зовнішній торгівлі торгівлі товарами, в тому числі агропродовольчими. Робота виконанана на основі широкого використання методів економіко-статистичного аналізу. У роботі доведено, що на територіях сірих зон, окупованих регіонах та регіонах в яких ведуться військові дії було зосереджено значний виробничий та експортний потенціал країни, а його руйнування і неповне використання вплинули на результати експорту за весь 2022 р. Досліджено регіональну та товарну структури експорту товарів, а також фінансові результати експортно-імпортної діяльності. Встановлено, що зміни в регіональній експортній структурі вплинули і на зміни в товарній структурі, а саме –продукція агропродовольчого комплексу займає більше половини експорту товарів. Показано, що провідна роль агропродовольчої продукції в товарному експорті проявляється і в створенні активного сальдо, в якому частка цієї продукції в 2022 р. склала 77,3%. В умовах війни держава має підтримувати певний рівень товарного експорту для гарантованого отримання коштів, і в цей період це може бути продукція сільського господарства і харчової промисловості. У висновках представлено рекомендації стосовно можливостей розширення експорту і скорочення імпорту, в тому числі за рахунок внутрішнього виробництва.
The role of reputation in cross-regional buyer-supplier cooperation in public procurement
Authors:   National Research University Higher School of Economics, Moscow, Russia, Russian Federation, Emelianova Milena K.
Published: November 2023

Relevance. The relevance of this study is determined by the growing trend of implementing approaches from the private sector in managing public procurement, such as suppliers’ reputation assessment. Although the suppliers’ reputation factor is a topic of current interest, both in research and in public procurement practice, there are ongoing discussions on the effects of the reputation criterion usage in public procurement, and some aspects have been insufficiently studied. Purpose of the study. This study examines the role of suppliers’ reputation factor in terms of interregional cooperation between public buyers and suppliers at the micro and regional levels. Data and methods. The analysis is based on a survey of public buyers in Russia, revealing procurers’ orientation on suppliers’ reputation factor and their involvement in cross-regional cooperation for micro-level analysis. With the help of open data on public procurement contracts, a grouping of Russian regions by the share of suppliers from other regions is proposed. The combination of open data analysis and survey results is then used to explore the role of reputation in terms of interregional cooperation. Results. The analysis shows that a suppliers’ reputation factor is of particular importance when more than half of a buyers’ suppliers are from other regions. Also, suppliers’ reputation is of major significance for public buyers in regions that are more involved in contracting with suppliers from other regions. Thus, the importance of the suppliers’ reputation factor, in terms of interregional cooperation, is confirmed both at the micro level of procurers’ purchases and at the regional level. Conclusion. For effective management of contractual relationships in public procurement, it is important to understand the effects and the role of considering the reputation of suppliers. The study focused on one of the insufficiently explored aspects of suppliers’ reputation in public procurement. The results may be of interest both to regulators and direct procurement participants – public buyers and suppliers.
DARCY-FORCHHEIMER FLOW OF A CONDUCTING MICROPOLAR FLUID AT A STRETCHING SHEET WITH CONVECTIVE BOUNDARY CONDITIONS
Authors: Meenakumari Ramamoorthy , Sucharitha Gorintla , Lakshminarayana Pallavarapu , Vajravelu Kuppalapalle
Published: November 2023

In this paper we study the Darcy-Forchheimer flow of a magnetohydrodynamic (MHD) micropolar fluid over a
stretching surface with convective boundary conditions. The effects of viscous dissipation, thermal radiation, activation energy, and chemical reaction, along with Dufour and Soret effects, are considered and analyzed. By using a suitable similarity transformation, the governing partial differential equations (PDEs) are converted into a system of nonlinear coupled ordinary differential equations (ODEs). The non-linear ODEs are solved numerically by a shooting
technique with the bvp5c MATLAB package. The effects of the physical parameters on the velocity, the micro-rotation,
the temperature, and the concentration fields are analyzed through graphs and tables. The present results are validated
with the results in the existing literature for some special cases. It is observed that an increase in the magnetic strength leads to a decrease in the velocity field. However, the thermal radiation parameter and the Eckert number significantly boost the temperature distribution. The concentration field is improved by the activation energy parameter. We believe that this investigation has a definite bearing to industries such as heat exchangers and lubricant refining process.
The role of format familiarity and word frequency in Chinese reading
Authors: Chen Mingjing , Lu Jiamei
Published: November 2023

For Chinese readers, reading from left to right is the norm, while reading from right to left is unfamiliar. This study comprises two experiments investigating how format familiarity and word frequency affect reading by Chinese people. Experiment 1 examines the roles of format familiarity (reading from left to right is the familiar Chinese format, and reading from right to left is the unfamiliar Chinese format) and word frequency in vocabulary recognition. Forty students read the same Chinese sentences from left to right and from right to left. Target words were divided into high and low frequency words. In Experiment 2, participants engaged in right-to-left reading training for 10 days to test whether their right-to-left reading performance could be improved. The study yields several main findings. First, format familiarity affects vocabulary recognition. Participants reading from left to right had shorter fixation times, higher skipping rates, and viewing positions closer to word center.. Second,  word frequency affects vocabulary recognition in Chinese reading. Third, right-to-left reading training could improve reading performance. In the early indexes, the interaction effect of format familiarity and word frequency was significant. There was also a significant word-frequency effect from left to right but not from right to left. Therefore, word segmentation and vocabulary recognition may be sequential in Chinese reading.

Authors:   The Korea International Trade Research Institute, Hong Won-Ki
Published: November 2023

Purpose - This research aims to analyze the effect of consumer lifestyle on the acceptance intention of fully autonomous vehicles, and the mediating effect of the safety of fully autonomous vehicles as the commercialization of fully autonomous vehicles approaches.
Design/Methodology/Approach - This research consisted of an online survey of 353 male and female adults in their 20s and order. The main variables are lifestyle, acceptance intention, and safety. To analyze the influence relationship, regression analysis was performed through SPSS, and mediation effect analysis was performed using Process Macro Model 4.
Findings - Consumer lifestyle affects fully autonomous vehicle acceptance intention and safety, and it has been proven that the safety of a fully autonomous vehicle has a mediating effect on the effect of consumer lifestyle on the intention to accept the fully autonomous vehicle.
Research Implications - First, the results proved that lifestyle is a new key variable in research on fully autonomous vehicles. Second, since safety has a mediating effect in the relationship between lifestyle and intention to accept fully autonomous vehicles, it was confirmed that safety is also an important factor. Third, in order to increase willingness to accept fully autonomous vehicles, it is necessary to segment the market based on consumer lifestyle above all else, and to develop a marketing strategy tailored to the characteristics of each lifestyle. Forth, in order to increase consumer awareness of the safety of fully autonomous vehicles, it is necessary to provide consumers with experiences based on Augmented Reality and XR technologies.
