Authors: DZHEIRANIAN A.D. , ERMAKOV I.D. , PROSKURYAKOV K.A. , LYADOVA L.N.
Published: November 2024

An approach to the development of data visualization tools is described that provides the ability to customize to the needs of users and the specifics of the domains in which they work, based on domain-specific modeling. The results of the analysis of data visualization tools and the possibility of customizing them to subject area based on the needs of users and the tasks they solve are briefly presented. It is shown that existing tools require programming skills from users to customize the data visualization format or to develop new visualization models. It is proposed to use domain-specific modeling tools (language toolkits) to create domain-specific languages (DSL) designed to develop new data visualization models that reflect the specifics of the tasks solved by users. The use of the developed tools does not require users to have professional knowledge of programming languages. The architecture of a knowledge-driven software system is described. The core of the system is a multifaceted ontology, which includes descriptions of languages and domains, as well as rules for generating new languages and transforming constructed models. Languages are designed to describe different classes of diagrams. The system includes tools for automating the creation of new DSLs by mapping the domain ontology onto the metamodel of the base language according to user-specified rules, which are also stored in the ontology. The classification of different types of diagrams forms the basis for creating an ontology of data visualization languages. An example of a basic language for creating diagrams is described. The ability to customize the DSL and transform visualization models developed with its help and generate code that implements the model is demonstrated.

COMPARATIVE ANALYSIS OF THE ACCURACY OF OPENFOAM SOLVERS FOR THE PROBLEM OF FLOW OVER A SPHERICALLY BLUNTED CONE
Authors: BONDAREV A.E. , KUVSHINNIKOV A.E.
Published: November 2024

The article focuses on a comparative assessment of the accuracy of various solvers within the OpenFOAM software package. An axisymmetric flow problem over a spherically blunted cone, utilizing a non-viscous compressible gas at a zero angle of attack, serves as the benchmark case for evaluation. The computational outcomes from different solvers are juxtaposed against established tabulated solutions. In addressing the benchmark problem, each solver is subjected to variations in the cone's half-angle and the incoming flow velocity at specified increments. The comparative analysis spans a broad spectrum of these critical parameters. Detailed analyses and graphical representations of the acquired results yield insights into the relative accuracy of the numerical methods applied to this specific class of aerodynamic problems.

Published: November 2024

Monitoring the interrelationships between social events and phenomena and forecasting the dynamics of their changes are necessary in the conditions of instability of the modern world. There are many separate methods of analysis for social forecasting, however, for this work, the method of event analysis has been chosen, which is insufficiently considered in the scientific literature within the framework of this task, but has high potential. The purpose of the article is to adapt the event analysis methodology for its use as a social forecasting tool. The main data for the study was collected from the Russian information and news resource in the period 2020-2023. Based on the classical methodology of event analysis, the classifiers presented in this paper in the form of social spheres are defined in the work. As part of the analytical comparison stage, a graph analysis was carried out (graphs of relationships between categories were constructed, central nodes-categories were identified); time series analysis was performed (segmentation of time series by the PELT algorithm, clustering of time series by the k-means algorithm); key terms for press events were defined. The final product is an analytical dashboard with filters, statistics and interactive graphs. The analytical dashboard makes it possible to compare data in a static and dynamic state, to draw conclusions about the past and future states of objects of social forecasting. The main result of the work is the event analysis methodology developed by the author, which can be used for a comprehensive analysis of news streams, adapted to the necessary categories representing a certain entity or sphere, and applied in various social organizations or monitoring services.
AUTOMATION OF VISUAL INSPECTION OF PRINTED CIRCUIT BOARDS
Authors: KHODATAEVA T.S.
Published: November 2024

Detection of printed circuit board surface defects is essential for quality management of printed circuit board production. However, detection of defects in the conductive pattern of the printed circuit board still remains a serious challenge, since even within the same category, defects have large differences in morphology and pattern. Although many computer vision-based detectors have been created to solve the problems, the problem of choosing a detector for these tasks that combines high detection accuracy, high detection speed and low memory consumption at the same time remains relevant. To study these issues, a study based on deep learning was conducted. Different versions of the YOLO convolutional neural network were studied on a proprietary dataset to test the efficiency and effectiveness. The need to create a dataset for training the network required the development of an image acquisition device. Formation of a dataset at a printed circuit board manufacturing plant using a specially designed image acquisition device. As a result of the work, the results of comparing the classic model of the fourth version of YOLO and one of the latest eighth versions of YOLO, trained on color and grayscale images, were obtained.
ENHANCEMENT OF GLARE RATING CALCULATION METHODS FOR 2-DIMENSIONAL HIGH-DYNAMIC RANGE IMAGES
Authors: BIRUKOV E.D. , KOPYLOV M.S.
Published: November 2024

This article describes different methods of improving glare rating calculation algorithms. Calculation of the glare rating using formulas that work with point light sources whose three-dimensional coordinates are known is not always possible. In some cases usage of a ready-made three-dimensional scene with known spatial coordinates of light sources, the observer's location, and the positions of other objects as input data, is impossible for different reasons. Instead, it is necessary to use a single two-dimensional image where the coordinates of light sources and any other objects are not explicitly specified. In this case, point light sources must be replaced with glare areas, i.e. groups of adjacent image pixels that satisfy certain conditions. An additional problem is usage of light sources with non-uniform spatial brightness distribution, which primarily include LED lamps, as well as daylight. This article proposes some improvements to the existing methods for calculating the glare rating for two-dimensional images. In particular, it is proposed to calculate the Guth position index using a weighted average sum of pixel brightness. This approach gives more adequate results, first of all, when using non-uniform light sources. It is also proposed to use an additional per-pixel mask to combine or exclude some glare areas. This approach is also used for non-uniform light sources, and also provides more accurate processing of glare areas of complex shape.
COORDINATE REFERENCING OF AN AUTONOMOUS UNDERWATER VEHICLE TO OBJECTS OF A SUBSEA PRODUCTION SYSTEM USING STEREO IMAGES
Authors: BOBKOV V.A. , KUDRYASHOV A.P.
Published: November 2024

Recently, the urgency of the problem of inspection of underwater infrastructure (gas and oil pipelines, subsea production systems (SPS), etc.) using autonomous underwater vehicles (AUVs) has increased as an alternative to the traditionally used technology of remote control of an underwater vehicle. Accurate localization of AUVs relative to objects is a key inspection task. However, the difficulties characteristic of the underwater environment do not allow for high-precision navigation based only on the sensors of the standard navigation system (hydroacoustics, inertial measuring unit, etc.). An alternative/addition to the mentioned navigation tools are technologies based on the use of computer vision, which can potentially provide higher accuracy of AUV navigation in comparison with the processing of acoustic measurements in local scenes at short distances to objects. Therefore, in this work, in the context of solving the problem of inspecting objects of an SPSs, we propose a new approach to solving the problem of recognizing underwater objects and the coordinate reference of AUVs to them, based on stereo image processing. Distinctive features of the approach are the use of a non-standard automated technique for generating a geometric model of an object from images of a survey trajectory, the use of different types of characteristic geometric elements (points, segments, angles) when recognizing objects, and the use of original algorithms for comparing the resulting visual data with an a priori model of the object.

Authors: ZHGUTOVA E.S. , BABAYAN P.V.
Published: November 2024

In this paper, the problem of estimating image alignment errors is considered. The purpose of the work is to develop algorithms and software to determine the dependence of the accuracy of estimating the parameters of various geometric transformations and evaluating the accuracy of image alignment on the location of reference points in the image. The object of the study is images of moving and stationary objects (cars, buildings) formed by cameras of the visible and infrared ranges, subject to geometric transformations. The paper presents a general algorithm for finding the correlation matrix for each type of transformation, the software is written in Matlab. The scientific novelty of the work lies in the fact that for the first time the dependence of the accuracy of estimating the parameters of geometric transformations on the location of reference points in the image was investigated. Experimental studies of the developed algorithms have been carried out in order to assess the errors of image alignment and the results of their work are presented in relation to typical images using the example of the Euclidean transformation. The importance of taking these errors into account when developing image processing algorithms is shown. The results obtained can be used in image stabilization algorithms, scene change detection, extraction and detection of moving objects.

Authors: KAMENSKIY A.V. , PODNEBESNYY A. , KURYACHIY M.I. , KUPRIYANOVA K.S.
Published: November 2024

When developing new algorithms for digital image processing, it is important to check the methods of their use and implementation. The five-cascade recursive-separable digital filter developed by the authors is a high-speed digital processing algorithm due to the use of recursion and separability properties. In the presented study, its effect on the signal-to-noise ratio was assessed when changing the shape of the processing aperture by adjusting the number of rows and columns in the processing aperture. The performance of the filter under study was assessed and a regular change in its operating time was shown. The change in the filter operating time varied in the range from 1.063 to 1.373 times, with an increase in the number of elements in a row or column of the processing aperture. As a result, an increase in the SNR from 17 dB to 28 dB was observed. The results obtained will allow laying the foundations for the developed methodology for using recursive-separable digital filters.

Authors: ZALISHCHUK A.A. , NENASHEV V.A.
Published: November 2024

In tasks of recognizing and identifying objects in images of the earth's surface, features have a high variability of angles and shades, which makes it difficult to use explicit algorithms. Neural networks have the property of contextual information processing using case-based learning and implement one of the approaches to solving unformalizable or difficult-to-formalize problems associated with image processing, and therefore the topic of the work has a high level of relevance. The goal of the work is to develop a system for recognizing people in images of the earth's surface using machine learning and technical vision technologies. Based on a comparative analysis of implementation options, the selection and justification of the neural network model used was made. When implementing and training the selected “YOLOv8” neural network model, optimization was performed using the “SAHI” slicing method, developed specifically for small object detection and fine tuning.

Authors: ZHDANOV D.D. , SOKOLOV V.G. , POTEMIN I.P. , VOLOBOY A.G.
Published: November 2024

The generation of realistic images for road scenes, physically correct design of illumination systems for roads requires the precise specification of optical properties for all scene elements and especially road surface. The reflection properties of road surfaces are complex and depend on a lot factors: material they are made (kind of asphalt, concrete), weather conditions (dry or wet road surface). Such reflective properties specified in while angular space can be determined with Bi-Directional Reflectance Distribution Function (BRDF). However, whole, and accurate BSDF measurements require complex equipment, and it is preferable to launch such measurements on-site. At the same time there are standard set of reflective properties presented in specification by International Commission on Illumination (CIE), so called reflection tables, so called “r-tables”. The properties defined by “r-tables” determine road surface reflection on very limited angular space and can be source incorrectness for visualization of road scenes. In the given paper it is showed the approach to transform CIE “r-tables” into more general BRDF format acceptable with commercial optical software, images of road scenes are generated as on the base of “r-tables” as well on entirely measured BRDF. It is presented the comparison of both approaches to describe road reflectance properties.

Published: November 2024

The efficiency of CAD designers is largely determined by the convenience of the graphical user interface (GUI). Modern CAD systems provide thousands of commands. Some of the commands are available in the GUI in the form of graphical elements. Some of the rarely used commands remain available only in manual input mode for experienced users, and the number of displayed elements is measured in hundreds. The purpose of the work is to implement the technology of forming a list of commands that best match the current context and accumulated experience of a CAD user. The developed solution uses modern machine learning algorithms (ML). A software library has been created that implements the technology. The library has been tested in integration with several modern CAD systems. The developed technology increases the efficiency of designers' work both through their own experience and through the transfer of knowledge in the form of ML models from more experienced engineers to less experienced ones. As part of the technology development, a data set was collected that has prospects for use in solving other CAD problems using ML methods. The technology has prospects for use in other types of applications.

Authors: SANZHAROV V.V. , FROLOV V.A. , GALAKTIONOV V.A.
Published: November 2024

Viewpoint selection methods for 3D scenes have various applications in computer vision, scientific visualization tasks, and in 3D reconstruction to reduce the training sample size. In this paper, we propose a method for viewpoint selection in application to material reconstruction problems based on inverse rendering using modified viewpoint quality scores as a loss function. The proposed method obtains viewpoints based only on the geometric characteristics of the 3D object and constraints on the camera positions and does not require some pre-known set of viewpoints. The proposed method is tested on an open dataset for 3D reconstruction.
OPTIMIZATION OF NUMERICAL METHODS FOR MODELING RADIATION TRANSFER IN A GAS-DISCHARGE MICROWAVE MERCURY-ARGON PLASMA
Authors: ZHELEZNOV I.I. , BUDAK V.P.
Published: November 2024

This article presents a mathematical analysis of the mechanisms of radiation transfer in a nonequilibrium low-temperature gas-discharge plasma, performed using the example of a low-pressure mercury-argon microwave discharge model. The authors propose a method for solving a system of kinetic equations and radiation transfer based on cubic discretization of the radiation source, representing a numerical solution of the Biberman-Holstein equation. To test the method, the geometry of a closed coaxial cylinder with a point excitation source in the center was used, simulating the radiation of an electrodeless microwave bactericidal lamp. The key results of the study are to obtain a solution for an arbitrary contour of the spectral line and to take into account the influence of diffusion, capture and reabsorption processes. These results contribute to a deeper understanding of the processes of radiation transfer in plasma and open up new opportunities for further research in this area.

Authors: Pan Yu , Gao Yuan , Yang Ping , Yu Guohua
Published: November 2024

Although gastrointestinal stromal tumor (GIST) can present with various histological characteristics, GIST mimicking perineurioma has not been previously reported. We present the case of a 47-year-old woman diagnosed with GIST after laparoscopic resection of a stomach tumor near the lesser curvature of the gastric body close to the cardia. Morphological features resembled a perineurioma. c.1504_1509 (p.A502_Y503) duplication was found in exon 9 of kinase insert domain receptor (c-KIT). This specific mutation is associated with constitutive activation of the c-KIT, which is crucial in the pathogenesis of GIST. Such unique histological characteristics broaden our understanding of the morphological diversity within GISTs and underscore the importance of considering an extended differential diagnosis when encountering atypical gastrointestinal tumors. This rare presentation may challenge conventional diagnostic criteria and could influence therapeutic strategies, emphasizing the need for comprehensive histological and molecular assessments in patient management.
Inhibition of lysine-specific histone demethylase 1A suppresses adenomyosis through reduction in ectopic endometrial stromal cell proliferation, migration, and invasion
Authors: Cui Limei , Sang Changmei , Li Ruoqing , Zhao Shuping
Published: November 2024

Objective:

Deep endometriosis is now referred to as adenomyosis externa, whereas adenomyosis is once known as endometriosis interna. Lysine-specific histone demethylase 1A (KDM1A, commonly LSD1) is a lysine demethylase that targets histone and non-histone proteins. This study aimed to assess how KDM1A affects the migration, invasion, and proliferation of adenomyosis-derived endometrial stromal cells (ESCs).

Material and Methods:

Immunocytochemistry staining was used to identify primary ectopic endometrial stromal cells (EESCs) and eutopic endometrial stromal cells (EuESCs) were isolated and purified from patients with complete hysterectomy for adenomyosis. Cell counting kit-8 assay, colony formation, wound scratch, and transwell assays were used to investigate the effect of silencing KDM1A on the inhibition cell viability, colony, migration, and invasion, respectively. Mechanistic investigations were carried out by Western blot and quantitative real-time polymerase chain reaction (qRT-PCR).

Results:

Vimentin staining was highly positive and cytokeratin staining was nearly negative in EESCs and EuESCs. KDM1A silencing reduced the ability of EESCs and EuESCs to proliferate (P < 0.001). The proliferation, motility, and invasiveness of EESCs and EuESCs were markedly reduced when KDM1A was silenced (P < 0.001). KDM1A silencing substantially downregulated invasion- and migration-related proteins or genes according to Western blot and qRT-PCR analysis (P < 0.05). EESCs and EuESCs with KDM1A silencing showed a higher reduction in these proteins than the control group (P < 0.05).

Conclusion:

In adenomyosis, silencing KDM1A can limit the motility, invasiveness, and proliferation of EuESCs and EESCs. These outcomes could potentially correlate with the decreased expression levels of matrix metalloproteinases (MMP)-2, MMP-9, Fascin, and Erzin proteins.
Comparison of efficacy of intralesional vitamin D3 versus intralesional triamcinolone acetonide in keloid – A randomized double-blinded non-inferiority study
Authors: Mohapatra Liza , Kar Bikash Ranjan , Singh Surabhi , Singh Bhabani STP. , Dixit Nibedita
Published: November 2024

Objectives:

Keloids are often difficult to treat and have a high chance of recurrence. Multiple modalities of therapy have been tried with variable success rates. Intralesional triamcinolone acetonide (TA) remains the most common modality of treatment of keloids. We have conducted a randomized controlled trial comparing the efficacy of intralesional injection TA versus intralesional vitamin D3 (VD3) in keloids.

Material and Methods:

Group TA (n = 30) received an intralesional TA 40 mg/mL, and group vitamin D (VD) (n = 30) received intralesional VD3 (cholecalciferol) 60000 IU every 4 weekly till 12 weeks and all the patients were followed up for another 4 weeks. At each session, the scar size was assessed by the Vancouver Scar Scale (VSS), and the Visual Analog Scale assessed the pain.

Results:

The mean score of VSS was significantly decreased in both group TA (7.91 ± 1.5–4.9 ± 1.6, P < 0.001) and group VD (7.84 ± 0.8–5.0 ± 1.6, P < 0.001). The pain was severe in group VD compared to group TA. There was fluid discharge with severe itching and pain in one keloid site in the VD group. The keloids reduced faster in size in the TA group compared to the VD group. There was no significant difference in response to TA versus VD.

Conclusion:

Both intralesional triamcinolone and VD3 were found to be efficacious with triamcinolone achieving a faster effect. The pain was a limiting factor in the intralesional VD group.
Antimicrobial resistance a continued global threat to public health – A perspective and mitigation strategies
Authors: Baruah Jutima , Shantikumar Singh Laishram , Salvia Thounaojam , Sarma Jyotishmita
Published: November 2024

Antimicrobial resistance (AMR) stands as an imminent menace to global public health, demanding meticulous scrutiny. The speedy expansion of resistant bacteria worldwide jeopardizes the effectiveness of antibiotics, which have altered medicine and saved several lives. The paradigm shifts from the antibiotic era to the era of resistance, particularly within Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species bacteria, which unfolds a pivotal narrative. Categorizing pathogens based on priority illuminates the critical imperative for novel antibiotics. An exhaustive exploration into bacterial resistance mechanisms unveils the intricacies of extended-spectrum cephalosporins resistance, multi-drug resistance, fluoroquinolone resistance, and carbapenem resistance. The complexity intensifies as these pathogens manipulate drug targets, enzymatically neutralize antibiotics, alter outer membrane permeability, and engage in active efflux. The paper discerns the grim repercussions of “Difficult-to-treat resistance,” accentuating elevated mortality rates. A focused analysis of public health, illustrated through the prism of the healthcare landscape, delineates the challenges arising from rampant antibiotic usage, healthcare disparities, and prevailing practices. To address AMR effectively, a comprehensive strategy is imperative. Innovative interventions, alternative treatments, and physicochemical methods are also contributing effectively. Similarly, systematic approaches, including national action plans, antibiotics, and stewardship, are crucial. This scientific exposition underscores the urgency of global collaboration, innovative interventions, and organized strategies to effectively counteract AMR, safeguarding public health in the face of this imminent threat. In this review, we focus on AMR mechanisms and potential strategies for mitigation.

Authors: Priyadarshinee Abhismita , Kini Saraswati , Ohri Alpana
Published: November 2024

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease with a variety of clinical manifestations and several immune-mediated abnormalities leading to multiple organ dysfunction. In adult-onset SLE, neurological symptoms and polyarthritis predominate, whereas in children and adolescents, lupus nephritis, hematological disorders, photosensitivity, butterfly rash, and mucosal ulceration are more common. We describe the case of a 16-year-old boy presenting with fever, rash, seizures, ultimately diagnosed with neuropsychiatric lupus. Laboratory findings, including positive autoantibodies and neuroimaging suggestive of central nervous system involvement, supported the diagnosis. Treatment comprised steroids, cyclophosphamide, and adjunctive therapy, leading to clinical amelioration. Neuropsychiatric SLE management focuses on symptomatic relief and halting underlying disease processes, often requiring immunosuppressive therapy. This case underscores the varied clinical spectrum of childhood SLE and highlights the pivotal role of steroids and cyclophosphamide in managing neuropsychiatric manifestations.
Linguistic deviation in the speech of Chinese students as a result of mixing languages (at the initial stage of studying Russian as a Foreign Language)
Authors: Gabdreeva N. V. , Khalimaimaiti N.
Published: November 2024

This article explores the methodology of teaching Russian as a second language, as well as the unique aspects of its acquisition by students whose native language is Chinese. It is noted that students universally make both general errors that are independent of their native language and specific errors that serve as indicators of their language proficiency. This paper presents a typology of errors commonly made by students whose first language is Chinese. Using the concept of linguistic deviation, this study examines the range of deviations in phonetic, lexical, grammatical, as well as syntactic aspects from standard Russian explained by differences between language systems at several levels in the mind of the emerging bilingual individual. The nature of these errors and strategies for their correction are considered. Additionally, the paper addresses the comparative ease with which educators can identify and rectify errors in students’ oral and written expressions versus the complexities involved in discerning inaccuracies in their comprehension of meanings. Through extensive practical engagement, educators aim to unearth, categorize, and address the diverse array of challenges and misunderstandings that Chinese students encounter in their acquisition of Russian, underlining the importance of their native linguistic background in this learning process. Guided by the insights of esteemed Russian linguist L.V. Shcherba, this study advocates for the constructive integration of students’ native languages into the learning environment, transforming potential obstacles into assets for language acquisition. By delving into these aspects, the article contributes to the pedagogical strategies for teaching Russian to Chinese speakers, aiming to enhance their linguistic proficiency and cultural understanding.

Published: November 2024

The paper focuses on the results of design and research activities aimed to define foundations of family values for young people living in the Far North. The work underlines the fact that design and research activities help strengthen family values. The paper aims to describe design and research activities with young students in determining the foundations of family values. At the North-Eastern Federal University, within the framework of the Federal State Educational Standard, organizing research work with students has always been strategically important. In the new realities, students are given a lot of opportunities for self-realization and for revealing their potential not only in their profession but also in various interdisciplinary spheres. In the recent years, according to the results of Rosstat for the Republic of Sakha (Yakutia), the  number of marriages decreases and that of divorces increases; in 2015, 7,668 marriages and 4,087 divorces  were recorded, and in 2023, 4,935 marriages and 4,036 divorces. These data reveal a family values-related problem looming in the Far North. To solve it, a clear understanding of family values of the modern young generation is required. The method of projective research activity allows, within the framework of the students’ project, to consider the definition of family values in detail, taking into account the climatic and socio-cultural characteristics that affect the young population of the Far North. Young students were selected as respondents because they are most likely to form new families. We believe instilling family values in students important, as they, having become a young family, strengthen the foundations of social institutions, which are the basis of the state.
The role and place of films in teaching Russian as a foreign language in the absence of a language environment: the case of working with Chinese students using the material of Melnikov’s short film “Vanka”
Authors: Samosenkova T . V. , Larionenko N. A.
Published: November 2024

The rapprochement of diplomatic relations between the Russian Federation and the People’s Republic of China has led to an increased demand in broad-based specialists capable of carrying out intercultural communication in Russian. Chinese universities are increasing the number of students in the specialty, where education is conducted in Russian. In the context of the continuing traditional approach to teaching, a foreign language, including Russian, and the emerging trend towards a communicative orientation of education, especially in the country’s language universities, make it relevant to search for new methods of teaching intercultural communication in Russian, especially in the absence of a language environment. The author of this article examines the use of such multimedia tools as films in Russian in the practice of teaching Russian as a foreign language, determines the advantages of using authentic videos with Chinese students of language and technical specialties. The result of the practical experience of using the authentic modern short film “Vanka” (2020) by Russian director Igor Melnikov in a Chinese audience is presented. Various types of tasks are presented and described at all stages of working with film materials. It is concluded that films have a number of advantages in solving specific educational tasks, and are an appropriate material for the formation and development of communicative, linguistic and cultural competencies. Also, methodically well-organized work with the film contributes to achieving a pedagogical effect, preserving the interest of Chinese students in the Russian language.
Philosophy of music in the context of mathematics
Authors: Danilova V. S.
Published: November 2024

In the philosophy of mathematics, two opposing trends have historically developed: apriorism (Pythagoras) and empiricism (Aristotle) and both of them have had their impact on the development of music. Philosophers of Ancient Greece and the East noted the important role of music; it was used in religious rites, which served as the basis for social and state relations. The article presents a joint panorama of the development (by historical eras) of the philosophy of mathematics and music and notes their close relationship. But if the Philosophy of Mathematics has long been included in the section of sciences «Philosophical Questions of Science», the Philosophy of Music has not yet acquired such a full-fledged status, although philosophers, specialists in aesthetics, art criticism, composers and musicians have dedicated their works to it. This can be attributed to the fact that since the time of Pythagoras, science has not advanced much in explaining the phenomenon of music. The article attempts to explain this paradox and offer as a hypothesis possible options for studying this topic «Mathematics and Music». The development of brain sciences, high technologies and cognitive sciences can contribute to the success in the development of the Philosophy of Music. The philosophy of music explores ontological, epistemological and axiological problems, the essence, historical and social existence of music, as well as the features of its interaction with art, literature, mathematics, natural and humanitarian sciences. Applied issues of the philosophy of music are the formation of ethical and cognitive guidelines for life and ideological ideals in humans. Music finds its practical embodiment in medicine, psychology, education and various means of communication. The latter is becoming the most important direction of modern philosophy and science. At present, mathematics contributes to the development of new integral directions in music associated with light, color and many other characteristics.

Aim. To determine the frequency and factors contributing to the formation of c-ma "hyperechoic pyramids" in children born with very low and extremely low body weight, as well as to assess kidney function in this contingent of children in a three-year catamnesis.
Materials and methods. A comparative analysis of the ultrasound pattern of the urinary system was carried out in 756 premature babies, from birth to 3 years of age, two groups were identified: group I – 133 children who had hyperechoic pyramids in the neonatal period; group II – 643 children without hyperechoic pyramids in the neonatal period; group III – the comparison group – 3000 full-term neonates.
Results. The symptom of "hyperechoic pyramids" was detected in 15% of premature babies (group I) by the end of 1 month of life (25±6 days), in full-term babies (group III) – in 23 at the age of the first 3–10 days of life. In 2% of premature infants up to 2 months of age, hyperechoic inclusions were diagnosed, giving an acoustic shadow, which were interpreted as kidney concretions. It was revealed that the need (100% vs 71%) and duration (9.7 days vs 2.8 days) for mechanical ventilation, drug load and frequency of artificial feeding (92% vs 19%) in the I group were higher than in the II group. By 12 months of age, signs of nephrocalcinosis with hypercalciuria in group I were detected in 74% of patients and by 36 months were preserved in 23%. In 2% children with renal nodules detected in the first months of life, these changes up to 36 months of life and by 3 years of age, the frequency in group I was 6.6%.
Conclusion. In children born with very low and extremely low body weight, there is a high frequency of detection of "hyperechoic pyramids," which tends to decrease with the growth of the child. In some children, the changes are persistent with a risk of progression in the absence of proper observation and treatment. Among the aggravating external influences, a significant role belongs to long-term mechanical ventilation and oxygen dependence, high drug load by various groups of drugs, as well as artificial feeding in neonatal and infancy.
Statins in the practice of an internal medicine specialist: A review
Authors: Susekov Andrey V.
Published: November 2024

Statins have been used in clinical practice for more than 40 years to treat and prevent atherosclerosis and its complications. The results of observational studies indicate that, despite a large evidence base, statins in Russia are still prescribed in low doses, for a maximum of 6 months, leading to a low percentage of achieving the target levels of low-density lipoprotein cholesterol and, thus, to a high residual risk of cardiovascular complications. This paper presents a literature review and analysis of the basic principles of statin therapy in primary prevention, intensive lipid-lowering therapy in patients with very high cardiovascular risk, as well as key safety updates on cholesterol decrease for various organs and systems (liver, kidneys, muscles, nervous system), and carbohydrate metabolism. The article also provides a brief overview of new international guidelines to optimize the diagnosis and treatment of dyslipidemias, which can be useful in the day-to-day practice of an internal medicine specialist.

Background. Diagnosis of autoimmune diseases remains a complex multi-stage process that includes various methods of laboratory testing. The gold standard for serological diagnosis of autoimmune connective tissue disorders is the indirect immunofluorescence assay (IFA) on HEp-2 cells. The result of the test is a description of the morphological pattern observed in the assay, which correlates with the corresponding autoantibodies and allows to direct further diagnostics. The most recent and most comprehensive attempt to describe HEp-2 IFA patterns was made by the International Consensus on Antinuclear Antibody (ANA) Patterns (ICAP).

Purpose. Ukrainian adaptation of the ICAP nomenclature was developed to provide for seamless harmonization and integration with international protocols.

Materials and methods. Ukrainian adaptation was based on the materials the International Consensus on Antinuclear Antibody (ANA) Patterns (ICAP).

Results. Ukrainian nomenclature of HEp-2 IFA patterns is provided in accordance with ICAP nomenclature, to be used a tool for comprehensive description of HEp-2 IFA results and guidance for clinicians

Conclusions. With the introduction and universal use of the Ukrainian adaptation of ICAP nomenclature, the laboratory diagnosis of autoimmune connective tissue diseases is approaching international standards, which creates conditions for the integration of international protocols for the diagnosis and treatment of these pathologies.
