Paleolithic Personal Ornaments from Xiaogushan Cave: The Formation of Early Symbolism and Its Regional Features in Northeast China

This article presents the results of a comparative study of personal ornaments from Xiaogushan Cave in the interregional and regional context of the formation of modern behavior. Xiaogushan is a Paleolithic and Neolithic site in Northeast China. In the Upper Paleolithic layers of the site, apart from tools, personal ornaments were found— pendants made from animal teeth, and a decorated bone disc. The date of the site is a matter of debate; ornaments from layers 2 and 3 date to ~30 ka BP. Like other bone artifacts (harpoon, needles, point), and together with types of stone tools and lithic technology, they mirror the local process of Middle to Upper Paleolithic transition. We focus on similarities between the Xiaogushan ornaments and Upper Paleolithic pendants from northern China and Eurasia in general, attesting to modern behavior during the transitional period and being an important marker of the spread of Upper Paleolithic innovations from the centers to the periphery. Xiaogushan is the fi rst Upper Paleolithic industry in Northeast China known to date, and demonstrates skills and symbolic behavior typical of the initial Upper Paleolithic. The Xiaogushan pendants follow the general tendencies, while being specifi c markers of the evolution of symbolic behavior in Eastern Eurasia.

Statistical approach and multiplicative models for electric vehicles charging behaviour patterns

Since the charging processes of electric vehicles are stochastic and time-dependent, the paper views an approach based on a statistical analysis of real data on electricity consumption at charging station connection points. Other types of data (geographical, public sites, distance between individual charging stations, etc.) are also taken into account when making the analysis. Multiplicative models are the most suitable for studying and forecasting time series with pronounced cyclicity and seasonality. Their application allows us to consider the correlation of the load in the consuming nodes with regional features, climatic factors and seasonality. The method and approach discussed in this paper make possible the processing of a large amount of data and the detection of load cyclicity in the load schedule of electricity facilities. The results of the model will identify the requested charging power in a developing charging infrastructure.

Analysis of lethal cases of pneumonia caused by SARS-CoV-2 virus according to the data of pathology department of Kharkiv Regional Clinical Hospital for the first half of 2021

Background. Given the great medical, social and economic significance of clinical research, pathogenesis and epidemiology of coronavirus infection, it is important to study the epidemiological and pathomorphological features of this infection in Ukraine, especially in fatal cases of this disease. Objective: to analyze the lethal cases of pneumonia caused by SARS-CoV-2 in comparison with lethal cases of pneumonia of other etiologies according to the pathology department of Kharkiv Regional Clinical Hospital for the first half of 2021. Methods. The material of this study was the observation of an autopsy from the archival material the pathology department of Kharkiv Regional Clinical Hospital. The study of autopsy protocols took into account the seasonality of the disease, sex and age of the deceased, the number of bed-days, data of clinical diagnosis and coincidences of pathological diagnosis, as well as the ICD code. 256 protocols of pathological examinations for the first half of 2021 were studied. Results. Of the 256 deaths from pneumonia of various etiologies, 201 (78.52%) were caused by SARS-CoV-2 infection. The highest number of deaths from pneumonia was registered in March, April and May 2021. The number of deaths of patients aged 18-44 years was 4.3% of the total, 45-59 years – 13.28%, 60-74 years – 47.27%, 75-90 years – 35.16%. The study sample among patients died of pneumonia caused by SARS-CoV-2 was dominated by women (57.42%, 147 cases), the number of men was 42.58% (109 cases). The direct causes of death were pulmonary-heart failure, multiple organ failure, acute pulmonary insufficiency, chronic pulmonary insufficiency, and pulmonary embolism. Conclusion. The obtained data can be useful for the analysis of regional features of epidemiology and pathogenesis of coronavirus disease in eastern Ukraine.

Legal support for preventing and combating land flooding in Ukraine

Due to global warming, over-regulation of water bodies, disruption of water runoff, poor functioning or complete lack of drainage systems, reduction of forest areas, our state will not avoid the problems associated with flooding. The harmful effects of water are due to global factors, such as warming and melting glaciers, as well as regional features, including the water exchange system between water bodies, changes in rainfall and river runoff. Land flooding is a phenomenon that cannot be completely prevented. However, human activity increases its likelihood and impact. The risk of flooding and the degree of damage caused, as well as the impact on the health and socio-economic situation of those affected, will continue to increase in the future due to climate change. Inadequate river management, construction in flood-prone areas and the growing population living in these areas exacerbate the effects of flooding. Ukraine has already taken appropriate steps to implement the provisions of international acts in the field of preventing and combating land flooding into national legislation. However, the quality of implementation of national programs in this area requires better, as most measures, unfortunately, are not implemented. Failure to implement measures in certain amounts creates high risks of flooding, as a result of which the population and the economy of the state suffer multimillion losses. Keywords: land flooding, harmful effects of water, threats and risks of flooding, basin-based water management, climate change, global warming

The secret of egg white fabric: an investigation of its fabrication and properties

The egg white fabric of the Dong Minority exemplifies their wisdom and represents rich regional features. It is renowned for its superior properties, especially its fabulous luster and excellent handle. However, the production method is rarely documented and instead has been handed down mostly by oral communication, and thus it is shrouded in mystery. In addition, due to low economic efficiency, a secret prescription and the challenges brought about by modern technology, this unique ethnic costume is threatened by extinction. Should this traditional handicraft be preserved or sacrificed? In this study, the secret of egg white fabric is solved by investigating its fabrication and properties. It is obvious that making egg white fabric involves complicated handiwork and numerous processes, including dyeing, fixation, brightening and starching; nevertheless, it has good physical properties. The experimental results indicated that egg white fabric has excellent texture, good thermal insulation, abrasion property and color fastness to laundering. Hence, this provides valuable inspiration for designers and manufacturers to produce unique and sustainable products.

Study of thunderstorm activity in Volyn Region and in Ukraine using the data of Blitzortung online resource

The article contains the results of statistical and graphical analysis of thunderstorm activity in Ukraine and within Volyn Region, in particular, following the study of the dynamic maps archive available at the online resource Blitzortung.org (lightnings and thunderstorms in real time). It describes the principles and results of activities of Blitzortung.org, a community of lightning direction sensors owners and users, and presents the developed algorithm of the methodology of reading dynamic maps available at this resource. Regional analysis of the archival maps on the website Blitzortung.org for 2008-2019 for the territory of Volyn Region made it possible to establish the following changes of the thunderstorm activity dynamics: the total number of thunderstorm days more than doubled (from 30 to 68.3 days on average); the number of thunderstorms increased in April (it was a rare phenomenon earlier); the number of thunderstorms increased significantly in May, for some years the number of thunderstorm days in May reached certain summer months (June and July); most thunderstorms are of frontal origin, storm fronts come from the west, north and southwest. The number of frontal thunderstorms tends to increase, therefore indicating increased atmospheric instability and the number of natural meteorological phenomena associated with such instability; the average monthly number of thunderstorm days in Volyn Region also increased for all months of the year with no exception. The analysis of storm activity within the whole territory of Ukraine during the period of 2018-2019 indicated the presence of clear regional features and differences. The increase in thunderstorm activity is observed in the western (50-100%) and southern (15-50%) regions of the country, and partly in the north. The number of thunderstorm days in the eastern part of Ukraine is close to the climatic normal. At the same time, the analysis needs to be clarified and detailed throughout the whole network of meteorological stations of Ukraine whose data can be compared with the results of the study of archival maps available at Blitzortung.org.

REGIONAL FEATURES OF INNOVATIVE DEVELOPMENT AND DIFFERENTIATION OF DIRECTIONS OF INNOVATION POLICY OF RUSSIA

In our manuscript we have made an attempt to study specific sides of Russian Federation’s innovative development, analyze its impact in economy growth and provide main ways of innovative policy realization in different types of regions. The method is based on partial abstraction from the unique properties of each region, thereby uniting them into homogeneous groups using k-means method. Further analysis of the determination of the main factor at the level of country was carried out using decision trees functions with the subsequent collection of OOB errors. Group analysis was carried out using regression analysis. As a result, the authors obtained five types of regions (with a high, above average, average, below average, low level of innovative development), provided an individual characteristic for each group regarding the innovation development and identified prerogative innovative factors that can be considered by the state as a criterion for differentiating state policy and regulation of the development of innovation policy.

Professional development of teachers in the context of digitalization of education: from conceptual ideas to practice

The article presents the results of a study of the practice of teachers professional development in the context of digitalization of education carried out in order to identify the features of teachers professional development and the main conceptual ideas implemented in different countries. The article examines the practice of teachers professional development in other countries as well as in a number of Russian regions. The analysis of pedagogical literature and scientific articles was carried out using the method of apperception and the descriptive method. The use of apperception method allowed us to expand information about the existing professional development practices implemented in different countries and regions. The use of descriptive method in working with scientific literature made it possible to select articles based on keywords, descriptors. In this study, the following phrases were used as descriptors: professional development of teachers, concepts of professional development of teachers, advanced training of teachers, practice of professional development of teachers. As a result, practices of teachers professional development have been identified that have both similar conceptual ideas and some national or regional features. Two of the conceptual ideas reflected in almost all countries are particularly noteworthy: that of continuity and that of personalization of teachers professional development in the context of education digitalization. Implementation of these ideas makes it possible to ensure continuous professional development of a teacher taking into account his or her professional experience, expertise, professional competencies and interests, as well as the interests and demands of the educational organization in which he or she works. The implementation of these ideas is carried out through integration of formal and non-formal education, as well as through self-education and self-development of teachers in the context of education digitalization.
