Microelectronics is widely used in various fields of science and technology: in modern control systems, radio engineering devices, devices and automation tools in industry, agriculture, transport and defense purposes. This determines the primary need for the development of this area. The strategy for the development of the electronic industry of the Russian Federation until 2030 is focused, among other things, on promoting Russian electronics to existing and international markets. Thus, the primary task is the legal protection of developments. Patent documents are an objective criterion for assessing the potential of technology development. The article evaluates the dynamics of scientific publications and patenting in the field of microelectronics in the Novosibirsk region, in Russia and in the world. This field is quite developed, the number of scientific publications and patents in the world has grown slightly over the past 20 years. There has been a decrease in the number of Russian patents in general and patents whose copyright holders are organizations registered in the Novosibirsk Region, in particular. This is a result of the deterioration of the political situation in the world. The imposition of economic sanctions against the Russian Federation was the reason why foreign companies were forced to stop investing in both research and development and in the production of Russian electronics. In these circumstances, some Russian companies have switched to protecting their developments in a trade secret mode. The main copyright holders and technology scientists working in electronic industry organizations registered in the region under consideration were also identified. The analysis of the level of development of microelectronic technologies in the Novosibirsk region was carried out, which showed that it corresponds to the world level.

The methodological possibilities of multimedia platforms in teaching a foreign language to cadets of a departmental educational organization are described. The advantages of using multimedia platforms in the course of organizing foreign language tutorials for cadets are considered, namely: the increase in learning motivation of cadets; communicative competence development; the expand of knowledge in the field of professional communication, culture and history of foreign countries; contribution to a qualitatively new level of organization of interaction between the teacher and cadets. It is noted that the use of multimedia platform resources in the organization of foreign language tutorials contributes to the exchange of information, and also improves the quality of education. The authors emphasize that the use of multimedia platforms in the process of a foreign language teaching to cadets of non-linguistic departmental educational organizations can increase their cognitive interest, immerse them in the language environment through the use of various methods and forms of active learning.
The article presents the results of experimental work on the use of multimedia platforms BBC Languages, Puzzle English in the organization of foreign language tutorials with cadets of the law and economic departments of the Academy of the Federal Penal
Service of Russia. The BBC Languages and Puzzle English platforms are designed for learning English. Among the advantages of these platforms, it should be noted: accessibility, level ranking of educational materials, the availability of audio and video materials, thematic notes, etc. Variants of the stages of work with cadets on the BBC Languages and Puzzle English platforms during foreign language tutorials, as well as in the process of organizing their extracurricular work, are proposed. Examples of class notes on the formation of reading, speaking, listening skills and the consolidation of lexical material are described. Based on the results of the experimental work, the authors came to the conclusion that the use of multimedia platforms in the process of teaching a foreign language significantly increases the efficiency of this process, contributes to the development of the communicative competence of cadets, the development of their cognitive interest, and the increase in learning motivation.

This study is devoted to identifying and revealing of the semantic content of the main cognitive features belonging to the concept WAHRHEIT (TRUTH), verbalized by the lexeme Wahrheit in the German linguistic culture, by identifying and describing the logems that fill them. The analysis is based on the semantic-cognitive approach, which involves the transition from the content of meaning to the content of sense. The research focuses on the definition of the ideological and value content of the concept WAHRHEIT on the material of the paremial fund of the German language with the help of sources that are freely available and contain paroemias with the lexeme Wahrheit.
In the course of the study, the authors identify the main cognitive features of the named concept: “Truth as justice”, “Truth as information” and “Truth as the most important life value”, which are presented by groups of proverbs varying in number. It has been established that the first place in the German linguoculture belongs to the cognitive feature “Truth as justice”, in which the lexeme Wahrheit is a synonym for justice. The cognitive attribute “Truth as information” is in the second place, it reflects the idea that truth can be a source of reliable information. The feature “Truth as the most important life value” is understood in a broad sense, the truth here is the most important spiritual value that exists not only on the Earth, but also in eternity. The analysis of cognitive features is carried out at the language level. Each proverb is interpreted in a broad sense, which makes it possible to identify the most obvious characteristics.
Each of the identified cognitive features is represented by a different number of logemes, which allows to judge the degree of significance of each logeme in the context of considering each cognitive feature. The most important logems of the cognitive feature “Truth as justice” are the logems “The power of truth” and “Justice is the source of troubles”. The logems of the cognitive feature “Truth as information” reflect both the belief in the arrival of certainty (the logem “The truth will be voiced”), and the bitter truth that earthly truth is surrounded by vices and bitterness. The logems of the last feature “Truth as the most important life value” supplement the main idea about truth, which has been revealed when considering the two other features, namely, a deep longing for the fact that the truth is not fully accepted by society.
The authors of the article are inclined to believe that the main ideas enclosed in the logemes of the German-language proverbs with the lexeme Wahrheit can also be applied to the characteristics of the German-speaking society, which gave rise to the paremic fund under consideration.

Systemic immune-inflammation index and the short-term mortality of patients with sepsis: A meta-analysis
Authors: Liang Lingbo , Su Qiaoli
Published: December 2024

The systemic immune-inflammation index (SII) is a novel biomarker that reflects the balance between the host immune response and inflammation, two key pathophysiological processes involved in sepsis. This meta-analysis aimed to evaluate the relationship between SII at admission and short-term mortality in patients with sepsis. Literature searches were performed in PubMed, Embase, Web of Science, CNKI, and Wanfang up to August 30, 2024, using relevant search terms. Observational studies that reported the association between SII and short-term mortality in sepsis patients were included. Risk ratios (RRs) and 95% confidence intervals (CIs) comparing the incidence of mortality within 90 days in patients with sepsis with a high versus low SII were calculated. Nine cohort studies, with a total of 25,626 patients, were included. A high SII at admission was significantly associated with an increased risk of all-cause short-term mortality in sepsis patients (RR: 1.51, 95% CI: 1.31–1.67, P < 0.001), with moderate heterogeneity (I² = 43%). Sensitivity analyses confirmed the robustness of these findings. Subgroup analyses suggested a stronger association in patients younger than 67 years compared to those aged 67 years or older (P = 0.04), but no significant differences were observed based on sex, SII cutoff values, or follow-up duration. In conclusion, this meta-analysis demonstrates that elevated SII at admission is associated with an increased risk of short-term mortality in sepsis patients, particularly in younger individuals. Further research is needed to validate these findings and explore their clinical implications.

Este estudo foca na relevância de monitorar a taxa de monóxido de carbono em bombeiros durante o treinamento de combate a incêndios estruturais nos simuladores da Escola Superior de Bombeiros. Tradicionalmente, a principal missão do Corpo de Bombeiros da Polícia Militar do Estado de São Paulo tem sido o combate a incêndios, situação em que os bombeiros estão frequentemente expostos ao monóxido de carbono, um gás comumente encontrado em emergências atendidas. O presente artigo foi desenvolvido para validar a hipótese proposta por meio de um procedimento metodológico baseado na coleta e análise de dados, adquiridos através de pesquisa de campo. O público-alvo da pesquisa foram os bombeiros, especialmente os alunos da Escola Superior de Bombeiros, com o objetivo de monitorar as variações na taxa de monóxido de carbono durante as atividades de combate a incêndios nos simuladores. Os resultados demonstraram que, durante os treinamentos em diversos cenários de incêndios simulados, os alunos apresentaram alterações nos níveis de carboxihemoglobina. A aplicação de procedimentos padronizados pode auxiliar na identificação precoce dessas alterações e garantir o tratamento adequado no contexto de atendimento pré-hospitalar, minimizando os incidentes relacionados ao monóxido de carbono entre os bombeiros.

Perpindahan Ibu Kota Jakarta Ke Kalimantan: Peranan Masyarakat Pantai Timur Sabah dalam Meminimumkan Impak Keselamatan Nasional (Jakarta Capital’s Shift To Kalimantan: The Role of Sabah’s East Coast Community In Minimising National Security Impact)
Authors: Ridzuan Mohamad Ikhram , Dollah Ramli , Ikfal Raharjo Sandy Nur
Published: December 2024

This study analyzes the impact of Indonesia’s capital relocation from Jakarta to Kalimantan on the communities along the East Coast of Sabah, Malaysia. It is undeniable that both countries have signed several agreements related to border security control, such as the Basic Agreement on Border Crossing1967, the Malaysia-Indonesia Border Trade Agreement 1970, the Joint Demarcation and Joint Land Border Survey 1973, and the Border Sea Trade Agreement 1973. However, issues like smuggling of goods, drugs, and human trafficking remain significant. Give these factors, the relocation of the capital from Jakarta to Kalimantan has the potential to increase smuggling, human trafficking, and the opening of new illegal routes, which could threaten the stability and security of both nations. This study, therefore raises two research questions: (1) What types of cross-border security issues threaten the relocation of the new capital, Ibu Kota Nusantara (IKN), along Malaysia-Indonesia’s land and maritime borders? (2) What alternative solutions can address cross-border security issues in both countries? The study applies the concept of the Grey Area Phenomenon (GAP), which analyses non-traditional issues in the post-Cold War era. To obtain more comprehensive findings, this research employs qualitative methods, including literature reviews and structured interviews. The findings indicate that border control involves not only the governments of both nations but also the role of local communities. This includes providing information to the government on smuggling and piracy activities, particularly from those living in the border areas between the two countries, as part of the efforts to reduce security threats.
“Bounded States”: How (Extreme) Risk Constrains the Aspiration for Status
Authors: Mbeva Kennedy , Makomere Reuben
Published: December 2024

We introduce the concept of “bounded states” to analyse how aspiration and risk (exposure and vulnerability to threats) shape the politics of status-seeking among states. We do so by examining how vulnerability to domestic and geopolitical threats constrain the aspiration of states for higher status in the international system, using the African Union Agenda 2063 strategic initiative as an illustrative case study. We draw on a review of key policy documents and secondary data analysis to highlight the tension between the collective aspiration for continental transformation and the catastrophic risks posed by climate change and geo-economic competition. We argue that African states, acting as “bounded states,” navigate these risks through a constrained version of Pan-Africanism—which we term as bounded Pan-Africanism—balancing their ambitions with the realities of high vulnerability to internal and external threats. In conclusion, this study offers new insights into the complex dynamics of status-seeking for states in a volatile global landscape.

В статье приводятся результаты применения нового методического подхода к определению целостности цикла расщепления на стоянке. В его основе лежит экспериментальное моделирование с последующим атрибутивным анализом полученной археологической коллекции. Подход базируется на динамике изменения доли отдельных типов технических снятий на разных стадиях нуклеусного и бифасиального расщепления, а также размеров сколов с кортикальной поверхностью. Разработанная методика была применена для реконструкции стратегии утилизации каменного сырья поздними неандертальцами Алтая на материалах Чагырской пещеры. Проведенные исследования показали, что наиболее распространенный в палеолитоведении метод, базирующийся на учете доли сколов с галечной коркой, не является универсальным и имеет ограничения, обусловленные структурой каменной индустрии и спецификой сырьевой базы. При использовании галек и валунов разных размеров, как в случае с комплексом из слоя 6в/2 Чагырской пещеры, высокая доля сколов с коркой может быть обеспечена производством бифасиальных орудий на стоянке. В рамках исследования удалось доказать осуществление начального этапа расщепления нуклеусов за пределами пещеры. Высокая доля кортикальных сколов в коллекции объясняется тем, что бифасы изготавливали на стоянке, а орудия на кортикальных сколах и их заготовки приносили в пещеру. Определена связь разных типов технических сколов с этапами расщепления нуклеусов и бифасов и установлено их количество в случаях полного и сокращенного циклов расщепления.

Статья посвящена оценке структуры, содержания и символического оформления дарообменных практик у каракалпаков на протяжении ХХ — в начале XXI в. Целью работы является обоснование природы дарообмена с использованием текстиля в традиционном и современном обществе каракалпаков. Исследование опирается на методологию изучения ритуального дарообмена в мировой и российской этнологии. В основе исследовательского подхода авторов — сравнительный анализ практик и идеологии дарения изделий из текстиля у тюркских народов Центральной Азии. При подготовке статьи использовались полевые, архивные и известные по опубликованным источникам материалы по этнографии каракалпаков, казахов, кыргызов, алтайцев и т.д. Структура работы включает разделы, в которых приводятся характеристики традиций дарообмена, даются анализ функций и символики текстиля в ритуалах, а также оценка тенденций их трансформации в современном обществе. По результатам исследования сделан вывод о том, что у большинства тюркских народов Центральной Азии дарообмен с использованием текстиля традиционно сопровождал многие социальные практики. Обмен отрезами ткани в семейных обрядах каракалпаков был обменом материальными и нематериальными ценностями; он маркировал передачу жизненных сил, способствовал сплочению родового сообщества. Как показал анализ актуальных практик дарообмена у каракалпаков, текстиль в них утратил свойства товара, но сохранил знаковую функцию на уровне социальных коммуникаций. Он стал символическим выражением взаимопомощи и солидарности на семейно-клановом, родовом, этническом и национальном уровне.

Creative Abilities and Incubation: The Poincaré Effect
Authors: Valueva E.A. , Ushakov D.V.
Published: December 2024

Incubation is a period during which a subject temporarily makes no conscious attempts to solve a problem but eventually arrives at a solution. Henri Poincaré described cases where insights came after a break from working on complex mathematical problems. This article proposes a hypothesis called the «Poincaré effect»: the higher a person's creativity, the more pronounced the effect of incubation in their creative process. An experimental study was conducted with 525 participants divided into a control group (without incubation) and an experimental group (with an incubation break). Participants performed the «Alternate Uses» test, inventing non-standard ways to use a matchstick. Creativity was assessed based on fluency (the number of ideas) and originality. The results showed that the incubation break led to a significant increase in the fluency of responses in the experimental group. Moreover, among participants with a high level of creativity, incubation contributed to an increase in the originality of responses, confirming the Poincaré effect. These findings align with the awareness model, according to which incubation helps restructure the problem representation and recognize previously found unconscious solutions. The study's conclusions confirm the presence of the Poincaré effect in the phenomenon of incubation and highlight the importance of individual creative abilities in the problem-solving process.
Actor's Personality in the Mirror of Psychodiagnostics: Past and Present (On the Example of Using the Cattell 16 PF Questionnaire)
Authors: Sobkin V.S. , Lykova T.A.
Published: December 2024

The article is devoted to the comparison of the results of studies of personality traits of student-actors carried out with the help of the Cattell 16 PF questionnaire during the last 50 years. The results of the studies of 1970—1990s conducted by different authors are given. The analysis of personality traits of modern student-actors is made on the basis of the author's empirical research implemented in 2010—2023. The studies involved students of the Moscow Theater College (2010—2018, N=188), Institute of Contemporary Art (2023, N=48), GITIS (2022-2023, N=67). In all the studies under consideration, the Cattell 16 PF questionnaire was used. The comparative analysis of the factors of the Cattell 16 PF questionnaire, for which the expressed high or low values in the studies of student-actors of different years were noted, showed that the general personality characteristic of student-actors during the last 50 years is emotional sensitivity. It was revealed that student-actors of 1970-1990 showed high scores on factor M “dreaminess” indicating developed imagination and abstract thinking. In modern student-actors this factor is not expressed, they are characterized by aspiration to leadership (factor E), courage (factor H), emotional sensitivity (factor I). The reasons for the identified generational shifts are discussed: changes in the social and political situation, development of technology, growth of competition and change in the characteristics of professional acting. It is concluded that it is necessary to take into account the identified personal characteristics of student-actors in the organization of training at the university.
Factors in the choice of volitional regulation strategies among university students
Authors: Shlyapnikov V.N.
Published: December 2024

The article presents the results of a study of volitional regulation strategies in university students. The hypothesis was tested that the choice of strategy is determined by the nature of the tasks facing students related to self-organization of educational activities, as well as individual characteristics of students: volitional, motivational spheres, self-awareness and psychodynamic properties. To test the hypothesis, students of different levels of education studying in full-time and distance learning departments were compared using a single-factor analysis. A total of 698 people took part in the study. The multiple linear regression method was used to test the influence of individual characteristics. The following methods were used: "Action Control Scale", "Questionnaire for identifying the severity of self-control in the emotional sphere, activity and behavior", "Brief Academic Motivation Scale", PIL test, "General Self-Efficacy Scale", a modification of the Dembo-Rubinstein self-assessment technique, "Big Five Short Portrait Questionnaire (B5-10)". To assess the strategies of volitional self-regulation, students were offered a list of ways to solve problems that arise in the course of their studies, which they had to evaluate by the frequency of their use. Then, the students' answers were processed using factor analysis. As a result, six strategies were identified: "planning", "self-regulation", "self-compulsion", "additional classes", "seeking help", "detachment from the problem". It was shown that full-time and distance learning students differ significantly in five of the six strategies. Master's students more often resort to self-regulation, bachelor's students more often seek help, and specialist students more often resort to self-compulsion. It was also shown that the choice of strategies is significantly influenced by the characteristics of volitional regulation and academic motivation of students.
Psychophysiological Markers of Executive Functions during Copying Sentences
Authors: Momotenko D.A. , Gorbunov J.A.
Published: December 2024

Typing is a multi-level process involving executive and motor functions. Due to its hierarchical organization, it becomes possible to study the psychophysiological features of higher mental functions in the natural environment by analyzing automated motor activity. The purpose of this work is to identify psychophysiological correlates of executive functions through computer typing. This study presents two EEG experiments aimed at copying sentences. The level of development of executive functions was measured using the UNIT and BRIEF-2 techniques, the sample consisted of 49 people (Age: M (SD) = 18.64 (0.74)), who previously confirmed the automation of the typing skill. According to the results of the study, regression models were constructed that reflect the dependence of the level of development of executive functions on alpha, beta and theta rhythms that arise during the printing of copied sentences. It was found that the higher the level of development of executive functions (braking, switching and working memory), the higher the power of beta rhythms in the prefrontal and frontal areas. Summarizing, we can talk about the significant contribution of executive functions to the typing processes, and about the possibilities of potential development of EF, by automating typing.
Clinical masks of primary cardiac tumors: a clinical case report
Authors: Uryas’yev Oleg M. , Solov’yeva Aleksandra V. , Berstneva Svetlana V. , Kostyuk Anastasiya V. , Samokhina Yuliya A.
Published: December 2024

INTRODUCTION: Primary cardiac tumors are rare, 75% of them are benign, half of which are myxomas. Despite histological benignity, untimely diagnosed myxoma can have serious complications. Myxoma is characterized by non-specific symptoms, however, a typical triad of atrial myxoma symptoms is distinguished: (1) symptoms of mitral valve obstruction manifested by heart failure and weakness, (2) symptoms of embolism and (3) systemic manifestations.
AIM: Illustration of the variety of clinical manifestations, discussion of diagnostic difficulties, formation of clinical alertness in the observation of left atrial myxoma.
MATERIALS AND METHODS: Left atrial myxoma in a 49-year-old male patient debuted at the age of 44 with the development of a transient cerebrovascular disorder in the right carotid system manifested by dysarthria and paresis of the facial muscles; at that time, no echocardiographic (EchoCG) examination was conducted. Several years later, the clinical presentation of heart failure manifested: shortness of breath when walking, edema of lower limbs. EchoCG revealed a sizable mass in the left atrium 33 mm × 55 mm fixed to the interatrial septum, prolapsing into the left ventricle and partially stenosing the left atrioventricular opening. Dilation of both atria, of the right ventricle, pronounced pulmonary hypertension, 2-degree regurgitation on the tricuspid valve, 2-degree regurgitation on the pulmonic valve, hydropericardium and hydrothorax on the right were found. The clinical case was also characterized by the developed bilateral thrombosis of the superficial femoral vein with signs of flotation. The development of venous thrombosis in a patient with cardiac myxoma can probably be considered as a systemic manifestation of the tumor disease. After compensation for the heart failure and implantation of a cava filter, the tumor was surgically removed, the morphological picture corresponded to cardiac myxoma with hemorrhages of various ages.
CONCLUSION: The case demonstrates the need for performing EchoCG in a transient ischemic attack, in ischemic stroke, to screen for intracardiac masses capable of frustrating cerebral circulation by cardioembolic mechanism, especially at a young age in the absence of other cardiovascular risk factors. The clinical picture consistently showed all the symptoms of the classic triad of cardiac myxoma: embolic syndrome, symptoms of mitral valve obstruction and systemic manifestations. The prognosis for patients with cardiac myxoma depends on the severity of thromboembolic syndrome and severity of heart failure. Timely diagnosis and surgical removal of cardiac myxoma provide a favorable prognosis.

INTRODUCTION: Uveal melanoma (UM) is an oncological disease, which develops metastases mainly to the liver. One of treatments for this pathology is isolated hepatic chemoperfusion (IHCP). The implementation of this method requires surgical isolation of the liver from the systemic circulation and the use of a heart-lung machine. Due to a small number of observations of this treatment method in the world, the optimal vascular access for its implementation has not been determined so far.
AIM: To analyze the in-hospital results of IHCP in patients with UM metastases performed from three different vascular accesses.
MATERIALS AND METHODS: Over three years, 38 IHCP procedures were performed of the Kostroma Clinical Oncological Dispensary. Depending on the vessels into which the cannula for perfusion with Melphalan was inserted, patients were divided into 3 groups: group 1 with cava-porto-arterial access (perfusion into the inferior vena cava, portal vein, and common hepatic artery), n = 14; group 2 with cava-arterial access (perfusion into the inferior vena cava and common hepatic artery), n = 21; group 3 with a forced access, n = 3. The study took into account major complications: death, bleeding; and minor complications: tumor lysis syndrome, abscess of the left lobe of the liver, peritonitis, a systole, deep vein thrombosis of the lower limbs, hydrothorax, acute liver failure, anasarca, polyserositis, ischemic cholangiopathy, thrombosis of the common hepatic artery, detachment of the common hepatic artery intima. A combined endpoint was the achievement of at least one of the listed complications. In case of several complications in one patient, they were not summed up and were considered as ‘1’.
RESULTS: In the postoperative period, the highest number of bleedings including those requiring revision, was noted in groups 1 and 3. The combined endpoint in the total sample made 42.11% and was lowest in group 2. Fatal outcomes were recorded in 3 cases (2 in group 1 and 1 in group 2), and were caused by increasing liver failure.
CONCLUSION: The lowest number of complications IHCP was identified with cava-arterial access. Further continuation of the study is necessary to investigate the immediate and remote outcomes of IHCP.

INTRODUCTION: There are no data in the literature on the effect of a single intraoperative electrical stimulation (IES) on the condition of the muscles of the lower leg and foot in the long-term period after autoplasty of the sciatic nerve in adult rats.
AIM: To study morphofunctional characteristics of muscles of the lower leg and foot after autoneuroplasty of a resection defect of the tibial portion of the sciatic nerve and a single IES in adult rats.
MATERIALS AND METHODS: The experiment was performed on 30 Wistar rats who underwent autoneuroplasty (AN) after resection of the tibial portion of the sciatic nerve. Fourteen rats underwent a 40-munite IES session (AN + IES series). In 16 rats IES was not conducted (AN series). At 4 and 6 months after the operation, the tibial nerve function index (TFI) was calculated by analyzing rats’ paw traces on a walking track. At the same time, light microscopy and histomorphometry of paraffin and epoxy sections of gastrocnemius and plantar interosseous muscles were performed. A conventional control was muscles of intact limbs.
RESULTS: Atrophy and endomysial fibrosis were less expressed in the gastrocnemius of the AN + IES series in comparison with AN series, the effect was mediated by enhancement of vascularization. In plantar interosseous muscles at 4 months after the operation, the volume density of blood vessels in the AN + IES series was 7.35 (5.49; 8.69), which was greater than in the AN series — 3.43 (2.02; 5.59), р = 0.0196. Diameters of muscle fibers and volume density of endomysium were comparable. At 6 months after the operation, endomysial fibrosis progressed in both series, but in the AN + IES series, myopathically altered muscle fibers were less common. After 6-month observation, TFI increased (-47.95) in the AN + IES series and became higher (p = 0.0339) than in the AN series, in which TFI became even lower (-93.64) than it was after 4 months (-81.95) of the experiment.
CONCLUSION: A single IES permits to reduce the denervation alterations in the gastrocnemius and plantar interosseous muscles conditioned by damage to the nerve and maturation, and also to improve the tibial nerve function index in the long term after autoneuroplasty.

INTRODUCTION: There is an objective demand for models of sustainable recreational environmental management based on modern ecodiagnostics, landscape-environmental design and rehabilitation of the population. Achievements in molecular biology have expanded understanding of the role of environmental factors in pathophysiology of chronic dermatoses (CD). Of importance is analysis of the influence of environmentally friendly recreational urban landscapes on reducing the morbidity and increasing the inter-remission period in patients with chronic skin diseases.
AIM: To develop a universal model of landscape-environmental planning of the sustainable nature management territories for environmental recreation and rehabilitation of patients with CD.
MATERIALS AND METHODS: An analytical assessment of scientific opinions and methodological approaches to landscape-environmental planning is given. A system analysis of scientific publications, a comparative analysis of existing regulatory legal acts permitted to identify and evaluate problems of ecodiagnostics of recreational landscapes and rehabilitation of people with CD. A method of making a final environmental diagnosis of the territory was determined. A reconnaissance survey and route tours of the forest park of Ryazan were conducted, areas suitable for rehabilitation of urban residents including patients with CD, were identified. A survey was conducted among 112 patients with CD to elicit their perception of the rehabilitation urban landscape.
RESULTS: A universal model for planning territories of sustainable nature management for environmental recreation and rehabilitation has been developed. To make a final ecological diagnosis of the territory, ‘Method for diagnosing the suitability of land plots and for toxic monitoring of territories for health resort recreation and medical and environmental recreation using human and animal cell cultures’ has been proposed. An algorithm for developing an individual program of environmental rehabilitation of persons suffering CD has been summarized. An analysis of the survey questionnaires showed that 101 people (90.2%) noted the beneficial effects of the surrounding nature, reduction of stress and improvement of skin condition; 68 (60.7%) respondents suggested making improvements to the surrounding urban environment.
CONCLUSION: Well-equipped and comfortable green urban landscapes have a positive effect on the treatment and rehabilitation of patients with dermatological diseases. The use of a universal methodological model in planning urban recreational areas are relevant and timely. Actualization and modernization of landscape-environmental planning is an innovative task that offers an opportunity for multiplicative use of the developed model in public healthcare.

Aim. Demonstrate the practical significance of assessing the technical condition of traction electric locomotives during unsteady operating modes by analyzing the nature and causes of an emergency increase in the armature current of the NB–520V traction motor in traction mode. This study uses comparative analysis of trip file fragments from EP1 series electric locomotives at a locomotive depot.
Methods. A review was conducted on innovative methods for studying the unsteady operating modes of traction electric motors in locomotives. These methods help determine the causes of emergency armature current increases under various operating conditions. The emergency increase in the armature current was considered in the traction mode, for which the results of the fragments of the trip files were analyzed using a microprocessor-based traction motor diagnostic system installed on an EP1 electric locomotive.
Results. The proposed diagnostic methods allow for the detection of developing malfunctions early, preventing irreversible damage in traction motor operations. These methods also help plan the timing and volume of equipment repairs. The study identified the nature and causes of emergency armature current surges in the NB-520V motor during traction mode, which were linked to violations in standard operating modes of electric locomotives. A recommended procedure was developed for use in repair depots to identify and address unsteady operating modes of the traction electric motor.
Conclusion. Timely and correct diagnosis of traction motors can significantly reduce downtime during unplanned repairs, avoiding unnecessary costs for motor replacements. The developed algorithm enables efficient identification of the causes of armature current surges in traction mode, using diagnostic microprocessor systems on electric locomotives. These systems help develop preventative measures, reducing motor failures on the line and train delays. In addition to the recommended procedure for detecting traction engine malfunctions, the study highlights new opportunities for creating an integrated information and measurement system for monitoring and diagnostics, based on the current technical condition of locomotive equipment.
