Mastering foreign languages is a deep process that covers several areas of human activity, including not only psycholinguistics, but also cognitive psychology, while affecting the area of interaction between consciousness and the unconscious. In the XXI century, a new technological basis has appeared, combining information and communication technologies and artificial intelligence. The systematic approach serves as a mechanism that allows combining modern technologies with those methods of teaching foreign languages that were previously available only to a narrow circle of specialists. The purpose of the research is to develop a training system created on the basis of modern information and communication technologies for acquiring speech skills of foreign language proficiency by adults on a massive scale. The article provides a brief description of the psycholinguistic aspects that can significantly reduce the duration of training. The proposed learning management system should work in combination with a methodologically precisely integrated linguistic system and ensure the formation of the speech zone of the acquired language in the adult learner’s mind during the learning process. The main result can be considered a conceptual solution to the problem of simultaneous interaction of the language system and the means of information and communication technologies that ensure the sustainable formation of foreign language thinking of adults in the process of developing professional and language skills, presented at the system level. And the introduction of the student’s psyche directly into the educational process management circuit should be considered as a new direction in the development of e-learning.

The methodology for preparing data for teaching neural networks is considered in solving two problems: checking the modality of computed tomography and checking the modality of radiographic images. The algorithm for preparing data for neural networks training is proposed. The influence of the stages (marking of images, normalization of data, determining the dynamic image range, the composition of the training sample) of the algorithm for the learning result is evaluated. The greatest influence in solving the task of modality verification of modality was the choice of optimal values of the dynamic range. The change in the composition of the training sample made it possible to increase the accuracy of the classification by 0.0073. When solving the task of checking the modality of images of computed tomography, the most impact on the result of the training of the neural network had the stage of data normalization. The assumption is put forward that there are special signs of images of this modality.

The lack of universal (generalized) data sets, as well as the lack of annotated data, creates the need to study the possibilities of neural network approaches for specific data sets. The importance of building algorithms for detecting extrapulmonary pathologies on chest X-ray images is dictated by the great social significance of many diseases of this group (for example, cardiovascular diseases), given the availability of such images, due to the widespread use of minimally invasive and relatively cheap X-ray diagnostic methods. One of the most impor tant issues in solving the problems of automating the classification of medical images is data preparation. As a result of work on the image base, the performance of the final algorithm has been increased from 75 to 95 %. The processing of the entire volume of the obtained images and their diagnostics for a wide list of pathologies are difficult for medical institutions because of the limited resources. In this regard, it is advisable to use the automation of segmentation and recognition processes, which even at the first stages of development of the technology makes it possible to redistribute the attention of doctors, focusing on potentially pathological cases and returning attention to cases mistakenly identified as non-pathological.

A method is proposed for delivering an absorbed dose to a target during brachytherapy for cervical cancer by using a new applicator, which consists of an annular part and two uterine canals. The design of the applicator makes it possible to implement it to the required depth, taking into account the anatomical features, to widely cover the cervix and corporis of a womb with a 100 % isodose of irradiation, which makes it possible to deliver the planned dose. The patient admitted to the brachytherapy department received the first treatment fraction using the Interstitial Ring applicator, the second and subsequent fractions were performed using the proposed applicator (6 fractions in total). In comparison with the standard applicator Interstitial Ring, the use of the proposed applicator made it possible to increase the coverage of the target with the prescribed dose from 69.2 to 95.5 %. This led to an increase in the absorbed dose per target for a course of radiation therapy from the planned 70.4 to 85.4 Gy. Twelve treatment plans for 3 patients were analyzed using different dose fractionation schemes. In all three cases, it was possible to increase the coverage of the target with the prescribed dose, which led to an increase in the total absorbed dose per target, which was more than 85 Gy. The proposed method has been successfully applied in the N. N. Alexandrov National Cancer Centre during brachytherapy for cancer of the cervix and corporis of a womb.

This paper presents the results of the analysis of existing methods for clustering data obtained during endoscopy of a larynx. A modification of the Viola-Jones method for image recognition using the flexible exit criterion is proposed. The Viola-Jones method explores all areas in the image and decides whether the recognized area belongs to the desired one by passing through a classified cascade. Endoscopic images have a large number of features, such as flare, noise, etc., which degrade the quality of recognition. To improve the quality of recognition, clustering with a flexible exit criterion was proposed, which satisfies the scalability criteria: changing the decision of the solution, instead of moving to another recognition area. It has been established that the proposed modification of the Viola-Jones method shows higher recognition results for endoscopic images.

The features of the bismuth oxide deposition by the ion layering method on matrices of anodic alumina and anodic titania have been studied. The formed nanostructured systems have been studied by means of electron micros copy, X-ray microanalysis, and X-ray spectroscopy. Two-layer nanocomposites consist of porous matrix or TiO2 island film with vertically oriented Bi2O3 plates placed on the surface. The photoluminescence spectrum of Al2O3/Bi2O3 oxide structure contains two photoluminescence channels with peaks at 460 and 560 nm upon excitation at 345 nm. Analysis of the EDX spectra showed that the atomic ratio of Bi, Ti and O was 31.46 % Bi : 3.78 % Ti : 51.05 % O. The possibility of using complex nanocomposite as contrast agents in X-ray diagnostics and for protection against ionizing radiation is shown.

The effect of reducing the damaged organ cell number and size in different areas of the human body (in case of carcinomas, cerebral thrombosis, heart attacks, damaged chest and cervical vertebrae areas, in case of coronavirus and dental pulpitis) was studied using a halogen lamp. The tests were conducted on patients when curing different diseases using periodic implementation of halogen lamp (500 W) with duration from 0.5 to 1 hour, while controlling its light frequency and intensity. The tests were carried out on a group consisting of 170 patients. The results were successful when it came to curing: coronavirus – up to 80 % success rate; cancerous tumors, strokes, heart attacks, and damaged parts of the cervical vertebrae – up to 70 % success rate; and dental pulpits – up to 90 % success rate. By analyzing the practical results received, one can come to a conclusion that the effect of reducing the number and size of damaged organ cells by using a halogen lamp can be used to cure many diseases. The most important is to cure COVID-19.

The article considers the problems of adaptation of existing and development of new diagnostic algorithms and methods of remote monitoring of the physiological state of a person in relation to the Internet of Things technology. In order to reduce the energy consumption of the wearable unit and biomedical signal sensors, reduce the redundancy of the recorded and transmitted diagnostic information, the critical situation recognition process is divided into two stages. At the first stage, the main indicators (heart rate and human fall signal) are monitored. If they do not comply with the norm, additional signals are analyzed (the second stage) to confirm the critical situa tion and determine the degree of alarm.

Motion capture systems are a key tool for performing quantitative analysis and evaluation of complex in movements sports. The prospect of the development and practical application of markerless motion capture tecnology in applied biomechanics increases research interest regarding the features of using such systems, as well as evaluat ing their accuracy and reliability in comparison with marker-based motion capture systems, which are the gold standard nowadays. Markerless motion capture systems have incomparable advantages over marker-based ones.In particular, significantly reduced time costs for the registration and data processing procedures, since registration is represented by filming a video from different angles, and processing is accompanied by the use of software algorithms for tracking the silhouette of an athlete using a presetted computer avatar. However, there is still no clear answer regarding the accuracy and reliability of the data recorded using markerless motion capture systems in relation to specific sports movements. Thus, the purpose of the presented work is to assess the statistical relationship of the data based on the correlation analysis of biomechanical variables on the example of a golf swing recorded using the Qualisys motion capture system and Simi Reality Motion markerless motion capture system.

This work aims at the development of a method of electromagnetic activation of salicylic acid molecules per se (SA) through the ultrasonic (20 kHz) complexation with oxidized zinc-graphene structure. The result of this work implies synthesized nanopartiсles “ZnO – partially restored graphene oxide (rGO) – SA” with the average size of (5.53 ± 0.11) nm and hexagonal wurtzite zinc oxide structure with complexed SA molecules. Complexation of SA with “ZnO – rGO” matrix causes magnification of electromagnetic field of SA by 102 times with the local enhancement at the contact with ZnO by 103 times, and therefore allowing selective electromagnetic activation of drug molecules. The developed method of “ZnO – rGO – SA” nanoparticles formation can be applied to many different drugs and drug-based devices, thereby introducing a great interest in medicinal electronics and nanomedicine.

The result of this work implies synthesized nanopartiсles “ZnO – partially restored graphene oxide (rGO) – SA” with the average size of (5.53 ± 0.11) nm and hexagonal wurtzite zinc oxide structure with complexed SA molecules. Complexation of SA with “ZnO – rGO” matrix causes magnification of electromagnetic field of SA by 102 times with the local enhancement at the contact with ZnO by 103 times, and therefore allowing selective electromagnetic activation of drug molecules. The developed method of “ZnO – rGO – SA” nanoparticles formation can be applied to many different drugs and drug-based devices, thereby introducing a great interest in medicinal electronics and nanomedicine.","PeriodicalId":33565,"journal":{"name":"Doklady Belorusskogo gosudarstvennogo universiteta informatiki i radioelektroniki","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42519730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
