Nos propusimos estudiar el grado de cumplimiento de las indicaciones médicas por parte de un grupo de pacientes jubilados. Materiales y métodos: Estudio cuantitativo-observacional-descriptivo-transversal en una población de jubilados del Departamento Iguazú, provincia de Misiones, Argentina. Se realizó una encuesta a través de un Formulario de Google Drive provisto a través de Whatsapp. Resultados: Fueron incluidos 46 jubilados, edad media: 70,95 años y franco predominio de mujeres. Las indicaciones médicas más frecuentes eran las medicaciones y los cambios de estilo de vida. Cuatro no cumplieron con las indicaciones médicas, todas eran mujeres, tres tenían secundario completo y una poseía título universitario. Dos casos no cumplieron con la medicación, no se realizó la radiografía y no se hizo sesiones de kinesiología. La radiografía no se realizó porque la dolencia cedió antes de conseguir el turno y en los otros tres casos de incumplimiento se debió a que sus coberturas no fueron autorizadas por su obra social. Como conclusión, la mayoría cumplieron las indicaciones médicas recibidas. La administración de la medicación fue la indicación médica que con mayor frecuencia no se cumplió, siendo la principal causa la no autorización de fármacos por la obra social. La falta de cumplimiento se vio exclusivamente en el sexo femenino y con educación secundaria y universitaria completa. Estos datos podrían contribuir a la determinación de políticas públicas que permitan un manejo directo, rápido y efectivo en la adquisición de la terapéutica correspondiente por parte de este grupo etario.

SEGMENTAL UNITS AS AN INDICATOR OF EMOTIONAL PERCEPTION OF THE SOUNDING SPEECH
Authors: Voropaeva I.V.
Published: December 2023

Problem Statement. Our research refers to the theory of emotionality and focuses on expressive means of sounding speech. When considering expressive means of sounding speech, we refer to the segmental level, namely to the distinctive features of vowel phonemes. We suggest that the complexes of semantic features of vowel phonemes and the frequency of their realization is one of the indicators of emotional perception and its correlation with a particular emotion. Besides it affects the perception of sounding speech in a particular emotional way, regardless of its semantics. The author has described and developed the mechanism of psycholinguistic experiment on revealing the perception of emotionally colored speech in connection with the functioning of the units of the language system in their differential attributes in the perception of sounding speech. Results.The results of the research showed that the distinctive features of vowel phonemes may be one of the indicators of correlation of emotional perception with a particular emotion. Moreover, when emotionality increases, one should expect regular and systematic changes of means for its expression. Furthermore, the polar basic emotions of both German and Russian speakers may coincide in the perception of the same material, which can be explained by the presence of universal and culture-bound specifics of emotional perception of the distinctive characteristics of vowels. Conclusion. Due to the results of the research, we may conclude that a systematic approach to the study of the phenomena of speech is possible because of the fact that the relationship between the functioning of the distinctive characteristics of vowel phonemes and the emotional coloring of the sounding text has a systemic nature.
EXTRALINGUISTIC INFLUENCE ON THE NOMINATION PROCESS
Authors: Ilina O.K.
Published: December 2023

Statement of the problem. The author proceeds from the idea that the study of the mechanisms of lexical nomination should be carried out taking into account the influence of extralinguistic factors on the linguistic means correlated with them. This article is devoted to the study of the nomination in Australian slang determined by extralinguistic factors. The author notes that there is no direct correspondence between the events taking place in the social life of people and the emergence of new linguistic phenomena. Neoplasms in the language are stipulated by the language structure. The aim of the work is to show how the events taking place in the country and the world are reflected in the nominative process of Australian slang. Results. The subject of the study was 1174 vocabulary units of Australian slang, which were analyzed in a diachronic way from the point of view of extralinguistic impact on the ways of creating new words. This study revealed the dependence of the nominative activity in Australian slang on a complex of external influences. So, at the initial stage of the development of Australian slang there could be traced two mechanisms of nomination, these are borrowing from aboriginal dialects and the creation of new lexico-semantic variants of borrowed words. Later, under the influence of significant events that took place in the country (the expulsion of convicts from Great Britain to Australia, increased sea traffic between the green continent and the outside world, gold digging, World wars I and II, strengthening contacts with other English-speaking states, the development of sports), the arsenal of nominative mechanisms in Australian slang gradually expanded. This was also facilitated by the deepening of relationships between people in Australian society. As a result, today, the inventory of lexico-nominative mechanisms in Australian slang is quite extensive including: the creation of new lexical-semantic variants of words, the creation of set phrases, borrowing, compounding, suffixation, truncation of the stems of words, supplemented by suffixation, contraction and pragmatonymy. Conclusion. This study revealed the dependence of nominative activity in the field of Australian slang on a complex of historically formed and currently emerging external influences. The article shows lexico-nominative mechanisms operating in different historical epochs under the influence of extralinguistic factors.
DIFFERENTIATION OF ONE-WAY SPEECH ACTS OF REQUEST AND ENTREATY AT THE PROSODIC LEVEL
Authors: Groshev D.V.
Published: December 2023

Statement of the problem. This article is aimed at identifying the distinctive features of such one-way speech acts related to the directive as request and entreaty at the tonal, dynamic and temporal levels based on the modern German language. The relevance of the study is due to the fact that each speech situation has its own prosodic form, which, consequently, leads to the need to identify more detailed distinguishing features of each speech act. So, within the framework of the directive, one can single out illocutions that are similar in the induced effect, but differ in the nature of the implementation of the action. Results. As a result of an experimental and phonetic research, it was found that, despite all the identified distinctive features, the greatest differentiation between a request and an entreaty is observed at the level of intensity. However, there is a tendency to distinguish the two illocutionaries at the melodic level as well. The most differentiated part of the delimitation of the speech flow is a post-beat, namely the completion of the phonation. This section captures the differences at all prosodic levels. At the level of duration, the differentiation between the entreaty and request is not statistically confirmed. Conclusion. Entreaty, being a less calm statement than request, reflects its emotional component in the prosodic picture. This is expressed in the allocation of key semantic syllables by loudness, frequent and sharp acceleration and deceleration of speech throughout the entire utterance. However, the same illocutionary of the entreaty is dynamically expressed less than the request. All identified distinctive characteristics of the two illocutives may indicate different communication strategies that interactants use in the course of communication in order to achieve the maximum perlocutionary effect, which presumably will minimize or completely eliminate the likelihood of misunderstanding between interactants.
DIGITAL ENCYCLOPEDIAS AS A MEANS OF TEACHING FOREIGN LANGUAGES AT THE UNIVERSITY
Authors: Grigoryeva E.M.
Published: December 2023

Statement of the problem. Teaching foreign languages at school and university is a complex and multifaceted process. Undoubtedly, the organization of the educational process is impossible without the use of textbooks, workbooks and books for reading. Dictionaries and encyclopedias become an additional means of learning a foreign language. The focus of this study is the problem of using special encyclopedias in the process of studying a foreign language at the university, particularly, English encyclopedias while learning English at the university. The relevance of the study is due to the high interest in foreign languages and the need to know them on a sufficient level to achieve some goals. Results. Modern encyclopedias in foreign languages, presented both in printed and online formats, allow users to obtain the necessary information on the topic under study, as well as to get acquainted with new terms of the subject area being studied. The analysis of "World History Encyclopedia" is presented in the article. The data of this encyclopedia can be used by students of historical specialties studying history as the main discipline, and a foreign language as an additional subject. Conclusion. The conducted research allows us to conclude that the introduction of encyclopedia materials into the educational process makes it interesting and interactive, provokes students’ interest and contributes to a better memorization of information. Such encyclopedias are learner’s ones that is manifested in exercises to check the assimilation of the studied material. Moreover, the learner’s orientation can be seen on the example of sound files included into the encyclopedic articles that allows to listen to the data in the language being studied. The information in such encyclopedias is usually given in a user-friendly language. The introduction of graphic illustrations contributes to a more effective perception of the material.

Published: December 2023

Statement of the problem. Against the background of the abolition of Russian culture in European countries, we believe that Russian students need to develop general cultural and foreign language communicative competence on the best examples of world culture. British literature of the 20th century is directly connected with the events of life of the previous time and is represented by the works of such writers as J. Galsworthy, A. Conan Doyle, R. Kipling, W. Maugham, O. Wilde, H. G. Wells, B. Shaw, etc. British literature of the XX century is realist and modernist works, fantasy, detectives and science fiction represent the "golden age" of its heyday and reflects the changes taking place in society, the search for eternal truths and defense of traditional values for all. The purpose of the study is to develop the foreign language reading competence of students-trainee foreign language teachers of the 1st and 2nd years using the works of twentieth-century British literature. Results. The impact of the content form of literature on the worldview, attitudes, values of students is great and occurs regardless of the attitude towards social institutions. The impact occurs at conscious and unconscious levels. In pragmalinguistic terms, the speech genre of fiction narrative implements communicative strategies. Reading is a thinking process, which is managed indirectly through text selection, preparation of pre- and post-text tasks, and control of reading comprehension. The analysis of the results of the ascertaining stage revealed an insufficient level of knowledge of 20th century British literature in the experimental and control groups of students - future teachers of a foreign language. In this connection the experimental program aimed at the optimization of the process of teaching English and increasing the level of knowledge of the British literature of the XX century among students was developed. Conclusion. On the whole we came to the conclusion that the work with the content form of the British literature of the XX century represents a special culture of relationship with the students, contributes to the formation of values, independence, high motivation for cognitive activity. It is important to provide the assimilation of British literature of the XX century on the basis of the analysis of the biography of the writer, the basics of literary criticism, the impact of stories and the author's idea on human life.
QUANTITATIVE TAXIS IN THE ASPECT OF THE INTERCATEGORIAL
Authors: Arkhipova I.V.
Published: December 2023

Problem statement. This article considers taxis and quantitativeness in the aspect of their intercategorial interaction. These categories are considered from the standpoint of a centered approach and are characterized by mutual connections implemented in the segment of verbal and nominal quantitativeness. The focus is on deverbatives, verbs of iterative and phase semantics, as well as adverbials / attributes with quantitative properties. Results. The German statements with prepositional deverbatives and quantitative indicators were examined. In the course of the study, it was revealed that in the statements with prepositional deverbatives, in the presence of quantitative indicators (deverbatives, verbs, attributes, adverbials), the quantitative-taxis values of simultaneity and non-simultaneity are actualized which act as a result of various intercategorial integrations. Conclusion. In German statements with prepositional deverbatives containing different quantitative indicators, it is possible to realize of various variants of quantitative-taxis categorial situations of simultaneity and non-simultaneity – iterative-taxis, phase-taxis etc.
USING BIG DATA IN SEMANTIC RESEARCH: PERSPECTIVES AND APPROACHES
Authors: Nikitina V.V. , Ivanova A.M.
Published: December 2023

Statement of the problem. Digitization and technology are rapidly taking over various fields of humanitarian sciences, including cognitive linguistics that is developing new algorithms and methods of language research, with linguists being encouraged to acquire new skills in data collection and processing as well as to expand their sources of language materials. In cognitive semantics and discourse studies, the biggest game-changer has been ever increasing (to the points of apparent limitlessness) volumes of various language data from digitalized texts available on the Internet that effectively accumulate in and function as Big Data – data sets that are too multiple, large and complex to be processed by traditional, ‘by-hand’ methods. Extensive language data requires specific mining and analysis tools and techniques and imposes certain restrictions on its processing and interpretation. In this paper, the authors discuss approaches to processing (‘intellectualization’) of empirical linguistic data coming from various online sources via search engines and their overall reliability for cognitive semantics research. Results. The main argument is that to ensure the validity of the digital language data under study and credible study results, researchers should employ several data collection methods and tools, i.e., opt for methodological triangulation. The authors describe their methodology on a practical example and conclude that big data systems such as indexed digital texts can effectively replace native speakers as a source of credible information on a natural language semantics as well as improve the overall quality and verifiability of semantics studies. Conclusion. Considering the national segment of the Internet in a certain language (English, Russian, etc.) as a natural text corpus of high representativeness, the researcher can use it as a tool for testing various linguistic hypotheses. At the same time, it is necessary to reflect on the intrinsic qualities of big data, such as volume, velocity (swiftness of change), variability, lack of structure, valuableness, and the presence of “noise”, as well as carefully consider, design and test procedures for using search engines to collect big data in order to ensure the quality and verifiability of the results obtained.

Authors:   Petersburg University of Aerospace Instrumentations, Fomicheva Svetlana G. , Bezzateev Sergey V. ,   Petersburg University of Aerospace Instrumentations
Published: December 2023

The problems of protection for intelligent information systems are acutely relevant due to their application in the subjects of critical information infrastructure. The most difficult to identify are adversarial attacks on machine learning models, which are carried out during transfer and federative training of already pre-trained models. At the same time, the anatomy of adversarial attacks is rarely covered in the Russian-language segment of publications, and the defenses against them and mechanisms for evaluating protection against attacks on machine learning models are practically absent, which actualizes the need for the analytical review presented in the article. Purpose: the purpose of the study is to conduct an analytical review and a formalized description of the defenses for machine learning models that are the target of adversarial attacks. Results: based on the classification of attacks aimed at machine learning models, the modern principles of their defenses are formalized. Unlike existing publications, our review highlights and summarizes not only the types of attacks on machine learning models, but also the mechanisms of their implementation. The classification of existing methods of protection against adversarial attacks is carried out. Practical relevance: as a result of generalization, the necessary requirements for the construction of models protected from adversarial attacks are formulated. Discussion: The main attention when building protection mechanisms for machine learning models and evaluating their reliability should be focused on countering complex adaptive attacks that clearly identify and target the weakest links of protection.
DEVELOPMENT OF A FUZZY-LOGICAL CLASSIFIER OF THE PHASE STATE OF HYDROMETEORS FOR AN ALGORITHM FOR CLASSIFYING AREAS OF PROBABLE ICING OF AIRCRAFT IN X-BAND WEATHER RADARS

Icing is a dangerous meteorological phenomenon for aircraft and is a process of ice deposition on the external elements of the aircraft structure. In real conditions, the aircraft crew is not always able to quickly recognize the gradual deterioration of controllability, which usually occurs over a long period of time due to icing. This fact leads to emergencies. To prevent such situations, it is necessary to have timely and reliable information about the existing supercooled hydrometeors on the aircraft flight path, which will allow the crew to take preventive measures in a timely manner. The zones of probable icing are characterized by the presence of a large volume of super-cooled water in the liquid state. In the radar range, the liquid volume is characterized by the reflectivity of the meteorological phenomenon, and the phase state of water is characterized by the reflectivity and additional characteristics available only for radar systems with polarization processing of reflected signals. At the moment, there is no functionality for detecting supercooled liquid in the meteorological radars of the near airfield zone. The decision on the presence of icing can be made only on the basis of indirect signs and predictive models that do not have the necessary degree of reliability. This article proposes to use a radar that provides a full polarization scattering matrix of hydrometeors, which makes it possible to relate the characteristics of reflected signals to such parameters of hydrometeors as their size, shape, spatial orientation and dielectric state, from which one can proceed to practically important meteorological characteristics, including such, which cannot be obtained without taking polarization into account. Hence, the problem of detecting supercooled liquid water can be reduced to the problem of classifying hydrometeors. To solve this problem, the article pro poses a fuzzy-logical algorithm for the classification of hydrometeors specific to the phenomenon of aircraft icing and performed its initial training using simulation data. The effectiveness of the proposed classification algorithm has been analyzed. It is shown that the developed algorithm ensures the justification of the classification when observing hydrometeors in the case of dangerous icing of the aircraft of the order of 98%.

The steady growth in the level of motorization inevitably leads to congestion of the elements of the road network in the cities of our country. The intensity movements of road transport is an important indicator of accidents, as it determines the modes and conditions for the occurrence of accident-hazardous areas. At the same time, the state of controlled intersections is the most relevant. The consequence of an accident is a large number of factors of the Driver-Car-Road-Environment system. To predict this negative phenomenon, which is considered a failure in a harmoniously functioning transport infrastructure, it is necessary to study the accompanying conditions and their influence on each other in detail. Thus, in order to carry out the necessary reconstruction measures at emergency hazardous areas, including at controlled intersections, it is necessary to carry out high-quality calculations aimed at evaluating the effectiveness of the proposed measures, as well as designing control modes at intersections with the optimal configuration of elements. This article discusses a software approach to the integrated collection and preparation of data, the use of which makes it possible, on the basis of the obtained patterns, to solve the problems of harmonious, without significant failures, the functioning of any considered transport hub on the road network. These studies are a new round in the improvement of the road safety system, striving for zero deaths on roads. The complex solution, in the version proposed by the authors of the article, has a direct impact on the management of traffic flows in an accident-free mode, which has not been previously developed and applied, this is the scientific novelty of the work.

The task of creation a high efficiency powerful modulation path for Envelope Elimination and Restoration (EER) Power Amplifier does not lose its relevance due to the continuous increase in data rates and the associated expansion of the frequency bands used. Currently, it is promising to develop a modulation path suitable for use with a signal bandwidth of up to 100 kHz - 400 kHz. The currently actively developing digital radio broadcasting systems Digital Radio Mondiale DRM+ (100 kHz) and Real-time audio-visual information system RAVIS (100, 200 or 250 kHz) have such a signal bandwidth. The possibility of using signals with a frequency band of up to 100 kHz - 400 kHz in the HF range ionospheric channel is also being actively explored. This task at the power level of hundreds of watts can be solved using GaN FET transistors, which have begun to become commercially available. To design such devices, this article develops a method for calculating losses in a PWM modulator based on GaN FET transistors, its simulation is carried out and the analytical method of calculations is coordinated with the simulation results. It is shown that at a clock frequency of 1 MHz, the predominant loss component depends quadratically on the supply voltage. This makes it promising to use step switching of the supply voltage to increase the efficiency when amplifying signals with a large crest factor.

In this paper we consider the alternative way of development of spatial beamforming processing algorithm in time-domain under low-rank Massive-MIMO systems. It is well-known, that the telecommunication systems, which based on spatial multiplexing technology achieve following advantages: increase the spectral efficiency in many times due to spatial channel multiplexing gain, the beamforming technology implementation (effective energy distribution in the space). The organization of spatial filtering (the beamforming vector processing) – one of the most significant tools in MIMO-OFDM multiplexing. In this paper, we consider a new spatial filtering processing approach (precoding vectors calculation), which is a significant tool in large-scale antenna systems, due to the fact of smart processing of the radio narrow-beam implementation increases the efficiency of the communication system many times over. Nowadays, the spatial filter design algorithms with low computational complexity have attracted considerable attention from researchers seeking to improve existing MIMO-OFDM wireless communication systems. In the paper we developed basic algorithms for calculating precoding vectors in the frequency domain and proposed the time-domain precoder approach with aim to achieve the complexity reduction gain. The proposed method was tested on the geometric statistical simulation channel model QuAdRiGa according to the multipath channel scenario "3GPP-3D Uma-NLoS". We provide the assessment of whole presented methods and the evaluation range of discrepancies was revealed in the form of pictures of the correlation and integral metrics. The analysis of integral cumulative distribution function of simulation results shows the relation gap between accuracy of correlation metric and losses of beamforming processing recalculation approximately -0.5 dB for 1st layer. In conclusion of paper was revealed the fact that proposed SVD factorization for each impulse response did not take into account the beams and eigenvectors distribution over the whole frequency bandwidth

The monitoring problem of various environmental indicators is becoming more acute due to the intensification of the climate change dynamics on Earth. Assessment of the dynamics of carbon footprint reduction makes it possible to create predictive models of climate change. Earth remote sensing technologies and big data of satellite images actualize the use of machine learning methods to assess the dynamics of the carbon footprint. The aim of the study is to develop a pipeline of neural network models that improve the quality of satellite images for carbon footprint monitoring systems. Methods of increasing the resolution and augmentation of satellite image data for the Sentinel satellite family used an approach estimating the amount of the aboveground forest biomass. Results: it is shown that the correct use of modern techniques to increase the resolution of satellite images and their augmentation using well-tested in practice supervised and weakly supervised machine learning models allows us to achieve qualitative assessments of semantic segmentation for satellite images. The proposed neural network pipeline allows for a two percent increase in the average Jacquard index compared to the currently best models of semantic segmentation of images on the dataset created by the authors. In comparison with the metrics of the main pre-trained models, the contribution due to the increase in resolution allowed to increase the average Jacquard index by 3% from a value of 77 to 80%, and the contribution due to augmentation based on channel mixing additionally amounted to 2% from a value of 80 to 82.3%. Practical relevance: improving the quality of semantic segmentation makes it possible to increase the accuracy of estimates for the areas of aboveground forest biomass and other flora diversity, Discussion: High-resolution satellite images (5 m, 1.5 m) are rarely publicly available. By increasing the resolution of Sentinel-2 multispectral satellite images, it is possible to generate a sufficient number of high-quality images, but checking the relevance of synthetically improved satellite images without the presence of original standards remains an open problem.

The development of artificial intelligence systems necessitates the creation of methods to improve the quality of information processing. The values of target variables and predictors are formed under the influence of external and internal factors that affect their ranges. Phenomena such as concept drift lead to the fact that the model may lose completeness and accuracy of results over time. A method of automatic data segmentation based on clustering is proposed to improve the quality of machine learning algorithms. Classification models are trained on a variety of examples in which there may be outliers, noisy data, an imbalance of observed objects, which affect the qualitative indicators of the results. In many systems, the time intervals of the action of factors can be determined and formalized in advance. The sample generated for machine learning methods usually consists of tuples whose values are obtained under different conditions. The influence of influencing factors can be determined empirically, or automatically, using, for example, clustering methods. The main (difference) feature of the proposed method is that, based on information about the factors influencing the ranges of values of these factors, the sample is divided into subsamples. The selection of individual impacts makes it possible to determine the data areas in which the factor was influenced, evaluate their properties and assign a classifying algorithm that has the best characteristics of qualitative indicators. The results of experiments on a number of data sets are presented. They show that the proposed solution makes it possible to improve the quality of processing. The model can be considered as an improvement of ensemble methods of processing information flows and data samples. In the case of transformation of data properties, training a separate algorithm on a local segment makes it possible to reduce computational costs, compared with training a complex data processing model.

The paper presents a new algorithm with linear time complexity, depending on the effective channel memory, for estimating the resolution time and capacity of a frequency-selective communication channel using a linear receiver and a multi-position phase-shift keying signal. The main limitation of the method is the possibility of its application for frequency-selective communication channel with symmetrical amplitude-frequency response relative to the central frequency of the channel, which is equal to the frequency of the received signal. From a practical point of view, this method can be used in the construction of radio engineering systems with serial data transmission in narrow-band ionospheric decameter communication channels (3-12 kHz). The key features of this method are: 1) constant number of equations equal to 1; 2) linear dependence of the number of terms in the equation on effective memory; 3) a new, more accurate procedure for estimating the effective memory of the channel, which allows you to simultaneously determine the resolution time and capacity. These features provide an increase in frequency efficiency by reducing overhead costs for setting the parameters of a serial phase radio engineering data transmission system for HF communication channels with a bandwidth of 3-12 kHz.
