Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim Shinhye
Published: July 2022

Objectives The purpose of the study was to investigate Korean and native English teachers’ perceptions of online classes during the COVID-19 pandemic in terms of their technological pedagogical content knowledge (TPACK), techno-stress, teacher efficacy, and environmental support. The study also attempts to illustrate how the Korean and native English teachers have adapted to online classes during the COVID-19 pandemic and how their experience has affected their perceptions about online classes.
Methods Data were collected through a survey questionnaire and interviews. A total of 37 (27 Korean, 10 native English) faculty members responded to the questionnaire and twelve of them participated in the interview. The responses in the survey were analyzed to compare the participants’ experience in online classes and their perceptions and interviews were coded to illustrate their adaptation process of teaching online classes.
Results The results showed that there was no significant difference between the Korean and native English faculty groups in terms of their online class experience, and perception of TPACK, techno-stress, teacher efficacy, and environmental support. It was shown that the mean scores of TPACK and teacher efficacy were relatively high while their techno-stress was not high. The participants underwent the process of frustration, adaption, and reflection while coping with challenges of acquiring and utilizing technology-based instructional tools in their online classes. Though the participants were forced to adapt to online classes due to the COVID-19 pandemic, it helped them improve their technological skills and gain new understandings of their own classes and students.
Conclusions The online class experience provided the participants an opportunity to improve their TPACK and to reflect on their teaching methods, students’ perspectives, and colleagues’ support. It can be suggested that teachers need to be encouraged and challenged to adapt to new teaching environments through which they can improve their teaching efficacy.

The work is dedicated to the publication of materials from one of the settlement objects of the Okhlebininsky archaeological complex, located in the Iglinsky district of the Republic of Bashkortostan and belonging to the Kara-Abyz archaeological culture of the early Iron Age. A brief outline of the current state of the study of archaeological sites in the survey area is given. The results of complex archaeological and palynological studies of the cultural strata of the Okhlebininsky I settlement are considered, and the settlement's citadel deposits are studied in detail. As a result of the analysis of the spore-pollen composition of the deposits of the cultural layer, four representative spore-pollen spectra, which describe the existence of forest-steppe and forest landscapes, were obtained. The stages of change of vegetation and climate during the functioning of the settlement are characterized. Materials obtained from the citadel of the settlement testify that the Ubalar population begins to develop the site of the monument at the turn of the eras. The materials from the neighboring cape allow us to suggest that this site was developed earlier than the site of the Okhlebininsky I settlement, as evidenced by ceramic material. The findings of a numerous elevating cape confined to the side of the ravine and the material obtained from the pit 6 actualize the continuation of the research in the adjacent territory.
THE DUCHY OF LUXEMBOURG IN CONTEXT OF BURGUNDA-IMPERIAL RELATIONS 1438–1443
Authors:   Belarusian State University, Minsk (Belarus), Cherkasov D.N.
Published: July 2022

The article deals with the diplomatic struggle for the Duchy of Luxembourg, which unfolded in 1438–1443 between the Duke of Burgundy, Philip III the Good, and the heirs of the House of Luxembourg. Not only representatives of the two dynasties were drawn into the conflict, but also a number of the most influential princes of the empire, such as Frederick III of Habsburg, the Archbishop of Trier, the Dukes of Saxony. Lacking direct rights to inherit Luxembourg, the Duke of Burgundy was able to offer its proprietress, Elisabeth de Görlitz, who held the duchy as a pledge, more favorable terms than William III of Saxony and the Archbishop of Trier, Jacques de Sirk. Philip the Good managed to achieve the neutrality of Emperor Frederick III and and win the trust of part of the Luxembourgish nobility. The entry into the duchy of Saxon contingents under the command of Count von Gleichen prevented the Duke of Burgundy from taking control of Luxembourg in 1442. Negotiations that took place during 1442-1443. did not result in an agreement between the parties. Despite the fact that by 1443 the Saxons controlled most of the duchy, Burgundian diplomacy managed to create the legal preconditions for the conquest of Luxembourg.
THE CAUSES AND PREREQUISITES OF THE NAT TURNER UPRISING IN AMERICAN HISTORIOGRAPHY
Authors:   Tula Branch of the Plekhanov Russian University of Economics (Russia), Shumakov A.A.
Published: July 2022

In this work the author analyzes the causes and prerequisites of the Southampton slave uprising of 1831 based on the materials of journalistic articles and reports of the XIX century and academic works of the XX-XXI centuries. At the same time, the main emphasis is on considering the dynamics of changes in the interpretation and perception of this event in American historiography. Such an unusual choice of subject is dictated by the fact that it is this question, according to the author, that is decisive in the study of this phenomenon, because it leads to the essential characteristics of the phenomenon under consideration. The author identifies two sets of causes and prerequisites – objective and subjective, describing each of them in detail. In addition, he identifies three key stages in the history of the study of the Nat Turner uprising: 1831-1900 – the first attempts at analysis in the form of journalistic reports, 1900-1971 – the formation of a binary academic perception associated with the release of works by W. Drewry and H. Apteker, 1971-our time – attempts to synthesize two approaches. It is noteworthy that the latter did not lead to the creation of a new concept. As the main method, materialistic dialectics is used, which allows us to consider this phenomenon in dynamics and in accordance with the principle of historicism, as a specific historical method, retrospective analysis is used, which is best suited for establishing and characterizing cause-and-effect relationships.

The article deals with the conference of the Allies, which took place in Petrograd in early 1917, on the eve of the February Revolution. This conference was one of the last stages of serious cooperation between the member countries of the Entente and Russia. The article is an attempt to analyze the tasks of the French, British and Russian delegations, which largely determined their positions at this meeting. Each side pursued its own goals. The tasks of the allies were, first of all, to confirm the common interests of the members of the Entente, to coordinate the actions of the military command, and most importantly, to encourage Russia to start new active military operations on the Eastern Front as soon as possible. The goal of Russia, which confirmed its loyalty to its allied duty, was, first of all, to receive the maximum possible volume of military-technical assistance from partners in the alliance. In addition, the allies were very interested in the general state of affairs in Russia, the mood of the elites and the prospects for the development of political life in Russia. The paper examines the course of negotiations, notes the main issues and problems that caused the most heated discussions, summarizes the results of the conference, which determined the further prospects for cooperation between the allies in the framework of the 1917 campaign of the First World War.

Published: July 2022

The article deals with the folk medical knowledge of the Russian North in the second half of the 20th century, which includes several subsystems.The studied issues of folk medical knowledge as a complex of rational and magical practices, as well as the processes of its formation, belong to the sphere of fundamental science and at the same time are among the topical issues of our time, in particular, the problems of knowledge. The work was carried out mainly by the method of field research and was based on the author's field materials collected on the basis of several expeditions to the Russian North. The study of the topic of folk medical knowledge of the Russian North, which has not been the subject of a separate study so far, determined the novelty of the work. The study revealed the inextricable links between the rational and magical components of folk medical knowledge, as well as ways to transfer and preserve folk medical knowledge. The following conclusions were made during the study. Throughout the twentieth century. Traditional medicine occupied an important place in the life of the population of the Russian North. Folk medical knowledge of the Russian North is a synthesis of archaic mythological ideas and rational ones. Folk medicine in the Russian North in the 20th century. remained in demand, because it satisfied an important social order - the preservation of health and the treatment of diseases, and official medicine could not fully satisfy the needs of the inhabitants of the northern Russian villages. The bearers of folk medical knowledge were elderly women who were the keepers of traditional knowledge, and they passed it on to the younger ones. The mechanisms of transmission, perception, mastery of folk medical knowledge developed in traditional culture have been preserved to this day.
Malicious Use of Artificial Intelligence in Sub-Saharan Africa: Challenges for Pan-African Cybersecurity
Authors: Pantserev Konstantin A.
Published: July 2022

For almost two decades, Sub-Saharan African countries have been making significant efforts to ensure the rapid development of industries related to information and communication technology (ICTs) in the region. At present, all leading nations are placing greater emphasis on the development of hybrid intelligent systems capable of solving extremely complicated tasks. This includes Sub-Saharan African countries, which consider the development of advanced technologies to be an effective instrument for ensuring sustainable social and economic growth and solving a great number of the continent’s problems. It has become evident, however, that all technological novelties that should simplify our lives can be used for malicious purposes. The present study examines existing practices and risks of malicious use of artificial intelligence (MUAI) in Sub-Saharan African countries. At the end of the study, the author comes to the conclusion that the problem of ensuring information, psychological, and cybersecurity is common to all African countries, which creates a serious obstacle for their further sustainable social and economic development. Over the past decade, Sub-Saharan Africa has made significant efforts to elaborate a joint vision for counteracting cybercrimes and the malicious use of advanced technologies. But all the attempts to establish effective supranational instruments that would regulate the fight against cyberattacks at the Pan-African level and take into account the interests of the vast majority of African countries in this area have failed. This demonstrates the presence of serious contradictions among African countries, which, taken together, prevent the establishment of mutually beneficial cooperation even in such an important field as cybersecurity. However, until such cooperation is established, it seems unlikely that African countries will even come close to solving this problem, which means that their information space will continue to be subjected to large-scale cyber-attacks that pose a serious threat not only to the security of individuals, but also to national and Pan-African security.
Digital Challenge for the Arab World: Integration or Differentiation Factor?
Authors: Valiakhmetova Gulnara N. , Tsukanov Leonid V.
Published: July 2022

As Arab states integrate into the global digital space, they share its advantages and risks and are included in the construction of the international information security system. Considering the significant influence of the Arab world on the formation of the world political agenda and the global security system, the study of the specifics of the development of the Arab digital cluster at the present stage acquires not only academic but also political relevance. This article is devoted to the study of the current state, potential and limits of Arab countries cooperation in the field of digital security within the framework of inter-Arab cooperation in multilateral and bilateral formats, as well as interaction with the world leaders in the technological ‘race’. The analysis was based on the methodology of the Global Cybersecurity Index developed by the UN International Telecommunication Union. It includes five key parameters for assessing the readiness of modern states to repel cyberthreats: the regulatory and legal system of national cyber defense, technical capabilities, organizational structure, capacity development measures and international cooperation. Assessing the ‘digital landscape’ of the Arab states, the authors note that the political, financial, economic, historical, and cultural specifics of the Arab countries contribute to the formation of a special environment in the region for countering cyber threats and solving cyber security problems. On the one hand, the digital challenge is forcing the Arab states to overcome some differences, giving a certain impetus to integration processes. On the other hand, the ‘catch-up’ type, and spasmodic dynamics of the digital industry development in the region, as well as the heterogeneity and inconsistency inherent in the Arab world, combined with the traditionally high degree of conflict and the strong influence of external factors, create a heterogeneous and fragmented environment that prevents the formation of a collective response to challenges of the digital age.
Space and Counter-Space Activities of Great Powers in Outer Space
Authors: Islam Md Badrul
Published: July 2022

The article is dedicated to outer space as a space, including the Moon and other celestial bodies, open for exploration and use by all. Celestial bodies are natural resources of the common heritage of humanity. Their exploration and use for the benefit and discovery of all countries is the result of the ownership of all mankind. However, since the end of the 20th century and especially in the 21st century, outer space has gradually become militarized. This is due to changes in the system of warfare, which is likely to be heavily transformed in the coming future. In this transformational system, all domains of warfare will be interlinked and outer space will play a significant role. One example of such processes is the Gulf War, also called the First Space War, in which the US Army successfully used the outer space systems for its Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) activities. Since then, outer space has become an integral part of US military operations. Consequently, other great powers like Russian Federation and People’s Republic of China are also trying to develop the same capability to counter US dominance in outer space. Simultaneously, the US is continuing its counter-space capabilities to maintain the dominance in outer space. The growing dependence on outer space is not only applicable to the military operation but also to commercial and civilian activities. As a result, great powers are more actively engaging in various space and counter-space activities to pursue their national interests; such activity turns outer space into an arena for inter-state rivalry.
The Global Terrorist Threat in the Sahel and the Origins of Terrorism in Burkina Faso
Authors: Issaev Leonid M. , Korotayev Andrey V. , Bobarykina Daria A.
Published: July 2022

The article examines the reasons for the increasing terrorist activity in Burkina Faso after the revolution in 2014. For decades, the Sahel has been one of the most unstable regions in Africa and the Afrasian zone of instability. However, in the 2010s the Sahel has experienced a dramatic increase in terrorist activity: by 2015, the number of terrorist attacks there increased more than seven times compared to 2010. At the same time, the dynamics of terrorist activity in Burkina Faso had its specific characteristics compared to the rest of the Sahel. The growth of terrorism in this country was largely a consequence of the overthrow of the B. Compaoré regime. The new authorities were unable to maintain security at the same level. This can be explained, on the one hand, by the stable agreements that had been settled between Compaoré and terrorist structures. His resignation destroyed all the informal ties and agreements that the regime had established with regional jihadist organizations, freeing their hands to infiltrate Burkina Faso quickly and easily. On the other hand, the dissolution of the Regiment of Presidential Security (precisely the structure largely responsible for the fight against terrorism) after the failed military coup attempt of September 2015 played an important role. The new leadership stripped the country of the protection they had against jihadist organizations poised to infiltrate across the border into Burkina Faso. As a result, after 2015, a very safe country in terms of terrorism faced an unprecedented increase in terrorist activity.

Authors: Stepanova Lydia P. , Korenkova Ekaterina A. , Stepanova Elena I. , Yakovleva Elena V.
Published: July 2022

The article presents the results of research on the bioecological assessment of the effectiveness of the fertilizing properties of metallurgical waste in nutrient soils. As a result of studies to assess the toxic effects of water extracts from nutrient soils on the vital activity of daphnia (Daphnia magna), changes in the reaction of this test object were established depending on the composition of the components in the nutrient substrate. The degree of influence of the fertilizing effect of various types of nutrient soils based on soil, slag and zeolite on the germination, growth and development of seedlings of small-seeded vegetable culture of lettuce has been determined. Seed germination, plant growth and development are influenced by the water-physical properties of soils and the amount of available macroand microelements. The effectiveness of the use of visual and computer assessment of the color gamut of lettuce leaves for assessing the level of soil contamination by the intensity of nutrient consumption by plants is shown.

Heavy metals can be considered in the aquatic environment as natural archaeological components and their quantities have risen as a result of industrial pollution. Heavy metals do not degrade over time and their concentrations can only rise due to bioaccumulation unlike organic contaminants. In the recent period, fish consumption has increased significantly because of its nutritional benefits, as it is a vital source of protein, as well as being high in critical vitamins and minerals. Because of the presence of heavy metals in frozen fish, it is a global public health issue concern but their presence remains essential and important for human physiological activities. However, when concentrations exceed the established allowed limits, they can be detrimental. The aim of this study was to quantify the concentration of heavy metals in frozen fish samples selected from Baghdad’s local markets. Six samples (Cleaned Shrimps, Anchovy Fillets, Captain Fisher Shrimps, Mackerel Fillets, Super Fresh Kalamar Squid and Frozen Rainbow Trout) of common brands of imported fish were selected from Iraqi markets in Baghdad. Acid digestion with a mixture of (65% HNO3 with 37% HCL) was carried out to free heavy metals fromfish samples to prepare solutions for testing in atomic absorption spectroscopy (AAS) device. The results reveal that the element concentrations in the selected samples (Cr, Co, Fe, Cu, Ni, K, Zn and Mg) are within the acceptable levels, and are lower than the permitted exposure limits according to international standards. It is remarkable to mention that the quantities of (Cd and Pb) are lower than permissible exposure limits of cadmium (0.2 mg/Kg) and lead (0.5 mg/Kg), implying that these imported items could be consumed safely.

Nanoparticles (NPs) are used in industrial and biomedical fields, such as cosmetics, food additives and biosensors. One of the most important of these particles is magnesium oxide nanoparticles. The nanoparticles of magnesium oxideare diagnosed through several techniques, including the Atomic Force Microscope (AFM) and (XRD). Analyzing the structure of studied nano materials is useful to investigate their medical applications by influencing thyroid hormones such as thyroxine (T4), triiodothyronine (T3), and thyroid-stimulating hormone (TSH)in rat. A total of 15 Sprague-Dawley adult female rats were split into three groups, each group injected daily intraperitoneally of MgONPs at one dose (80 mg/kg).In different periods (14 and 28 days), as follows; The first group: is the control group without injections. The second group: injected intraperitoneally with MgONPs (80 ppm) for 14 days. The third group: was injected intraperitoneally with MgO NPs (80 ppm) for 28 days. The findings of this study revealed a highly significant reduction(p < 0.01) in T3, T4 and Thyroid stimulating hormones (TSH) levels increased high significantly (p < 0.01).

Dante as the Author of the First “History of Italian Literature”

Although the first histories of Italian literature appeared only in the 18th century, one may call Dante the first person who tried to describe and analyze literary works written in the Italian language (volgare) before him. Throughout his oeuvre, Dante not only described but also championed these works, which had recently replaced Latin literature and needed a justification. Dante was also concerned about affirming his own status as an “author” (auctor) who was on par with the great Latin writers. We examine the different stages of this process in accordance with the genres and goals of Dante’s works The New Life, the treatise De vulgari eloquentia, and Divine Comedy. Dante’s “history of literature” is unique both in content and form, just as he himself holds a unique place in the history of Italian literature.
