A. S. Butorova, A. I. Kosachenko, D. A. Tarasov, A. P. Sergeev

The process of globalization is inextricably connected with cross-cultural communications, and as a result, with the need to increase the effectiveness of learning foreign languages. Immersion in the environment of native speakers, implemented in virtual reality, could help to solve this problem. The application of virtual reality technology to the educational process raises the issues of identifying factors that affect the effectiveness of such learning. In this work, publications for analysis were collected from international scientific databases Scopus, Web of Science, PubMed according to a query formulated by the authors. The resulting sample contained 733 scientific sources. The final selection of sources was carried out according to three criteria: 1) the use of immersive virtual reality systems HTC Vive, HTC VIVE PRO, Oculus Rift, 2) the presence of a formative experiment aimed at acquiring knowledge in the language, 3) adults without clinical complications learn a second language. As a result, 13 experimental works were selected. These works were classified on the orientation of the simulator and on the formalization of the task. Papers on the orientation of the simulator were divided into speaking skills, memory, listening, social interaction and writing. According to the formalization of the task, simulators with free study of the environment and with strictly regulated tasks were allocated. The part of works dealt with the learning of a foreign language using immersive virtual reality was 1.8% (13 works out of the original 733). Of the 13 experimental studies, 8 showed a positive effect from the use of immersive virtual reality in learning a foreign language, the remaining 5 studies did not contain estimates of the effect.

GENERALIZED INDICATOR OF SOIL AND VEGETATION POLLUTION WITH COPPER AND ZINC IN THE AREA OF COPPER PYRITE ORE DEPOSIT

A. N. Medvedev, M. A. Medvedev

The article is devoted to the development of methodic for environmental monitoring of the copper pyrite deposits influence zone with the study of soil and herbaceous vegetation contamination with ore metals. Based on an analysis of known studies on the patterns of copper and zinc migration in the soil-plant system, a hypothesis has been put forward about the prospects of using the generalized indicator Ko, which is the sum of the normalized to standard values concentrations of copper and zinc in soil and vegetation. Testing the hypothesis using field sampling data showed that the position of the dump of overburden rocks of a copper pyrite quarry on the profile is clearly indicated by an increase in Ko by 60-120 % at the closest to the dump points. Taking into account the available data on the different nature of the copper and zinc accumulation in different types of vegetation, it was concluded that the proposed generalized indicator can be recommended for use in environmental monitoring of copper pyrite deposits influence zone to increase the information content and reliability of research.

INFLUENCE OF THE ANGULAR AND ENERGY SENSITIVITY DEPENDENCES OF THE INDIVIDUAL DOSEMETRES FOR THE PERSONAL IRRADIATION ASSESSMENT

I. S. Spiridonova, M. D. Pyshkina, A. V. Vasyliev, A. A. Ekidin

The energy and angular sensitivity dependences of the individual neutron dosimeters are investigated. The irradiation geometry study was carried out by modeling, reproducing the full picture of the interaction of the neutron field with the phantom. Due to information on
the energy and angular sensitivity dependences, the most accurate estimates of the effective dose under the influence of neutron radiation can be obtained. The paper presents the results of calculating the energy and angular sensitivity dependences of individual neutron
thermoluminescent dosimeters Harshaw 6776 and DVGN-01. Based on the data obtained on the individual dosimeters responses, a method for evaluating the accepted value of the effective dose was proposed.

CHANGES THE ENVIRONMENTAL SITUATION OF DONBASS REGIONS DUE TO MILITARY ACTIONS

G.Ya. Drozd, E.I. Verekh-Belousova

The article provides a deep and detailed analysis of the environmental consequences of military operations, which are one of the main sources of violation in the “man–nature” system. The results of the complex influence of all components of anthropogenic factors of hostilities on the atmosphere, landscape and soil in the zone of a special military operation in Donbass are presented. The scale and consequences for the ecology of the region of each of the factors are estimated. The main factors have been identified and studied: explosions, fires, displacement of earth masses, pollution and cluttering of the soil of the territory. The data obtained are unique, their reliability is confirmed by the results of a few researchers. The analysis of data of physical and mechanical destruction of soil because of battle actions is presented as a complex anthropogenic factor, characterized the types of influence and their consequences. Findings and results are reliable, unique and require the proper comprehension and reacting for renewal and ensure normal life in the territories.

BRIEF ANALYSIS OF SNOW REMOVAL IN A LARGE RUSSIAN CITY USING THE EXAMPLE OF THE CITY OF EKATERINBURG

А. V. Shevchenko, G. P. Malinovsky, A. A. Seleznev, I. V. Yarmoshenko

In this paper long-term data (2013-2023) on snow accumulation and snow removal from the territories of the street and road network and yard spaces in the city of Ekaterinburg are analyzed. According to the results of the study, the snow accumulation until the beginning of snowmelt is estimated at 106 kg/m2 on a 10-year average. On average, about 2.1 million tons of snow fall on city roads and sidewalks, 1.8 million tons on roadside lawns, and 1.6 million tons on residential areas (including 0.67 million tons on driveways and sidewalks). Approximately 57% of the snowfall is removed from the city’s streets and sidewalks to snow receiving stations, while the remainder is expected to be left on roadside lawns, roadside shoulders, and other elements of the street and road network. Doubling the amount of snow removal will significantly increase the period of normal functioning of the city’s infrastructure. In order to obtain a complete assessment of the current state of maintenance of all areas of the city in winter, it is necessary to additionally analyze the data on maintenance of areas not serviced by municipal enterprises.

REALIZATION OF ROC ANALYSIS TO DETERMINE THRESHOLD VALUES OF NEW ANTHROPOMETRIC INDICES BRI, ABSI, LAP

N.V. Bilash, E.D. Konstantinova, S.Yu. Ogorodnikova, T.A. Maslakova

The article presents the results of ROC analysis and determination of threshold values of the anthropometric indices Body Roundness Index (BRI), A Body Shape Index (ABSI), Lipid Accumulation Product (LAP), which allow identifying a risk group for metabolic syndrome (MS). We used retrospective data from 347 male workers employed in hazardous working conditions at five industrial enterprises in the Sverdlovsk region. A program was developed in the high-level general-purpose programming language Python. The possibility of implementing ROC analysis, determining diagnostic threshold values of anthropometric indices, as well as visual positioning of the cut-off point on the graph has been demonstrated. The obtained values were compared with the results of using the applied statistical package SPSS 29 (SPSS, Chicago, Illinois, USA). Diagnostic thresholds for four age groups, found using the written program, were: BRI – (4.1–4.4), ABSI – (0.079–0.083), LAP – (49.7–70.5).
