BACKGROUND

ChatGPT has shown impressive performance in national medical licensing examinations, such as the United States Medical Licensing Examination (USMLE), even passing it with expert-level performance. However, there is a lack of research on its performance in low-income countries’ national licensing medical examinations. In Peru, where almost one out of three examinees fails the national licensing medical examination, ChatGPT has the potential to enhance medical education.

OBJECTIVE

We aimed to assess the accuracy of ChatGPT using GPT-3.5 and GPT-4 on the Peruvian National Licensing Medical Examination (Examen Nacional de Medicina [ENAM]). Additionally, we sought to identify factors associated with incorrect answers provided by ChatGPT.

METHODS

We used the ENAM 2022 data set, which consisted of 180 multiple-choice questions, to evaluate the performance of ChatGPT. Various prompts were used, and accuracy was evaluated. The performance of ChatGPT was compared to that of a sample of 1025 examinees. Factors such as question type, Peruvian-specific knowledge, discrimination, difficulty, quality of questions, and subject were analyzed to determine their influence on incorrect answers. Questions that received incorrect answers underwent a three-step process involving different prompts to explore the potential impact of adding roles and context on ChatGPT’s accuracy.

RESULTS

GPT-4 achieved an accuracy of 86% on the ENAM, followed by GPT-3.5 with 77%. The accuracy obtained by the 1025 examinees was 55%. There was a fair agreement (κ=0.38) between GPT-3.5 and GPT-4. Moderate-to-high-difficulty questions were associated with incorrect answers in the crude and adjusted model for GPT-3.5 (odds ratio [OR] 6.6, 95% CI 2.73-15.95) and GPT-4 (OR 33.23, 95% CI 4.3-257.12). After reinputting questions that received incorrect answers, GPT-3.5 went from 41 (100%) to 12 (29%) incorrect answers, and GPT-4 from 25 (100%) to 4 (16%).

CONCLUSIONS

Our study found that ChatGPT (GPT-3.5 and GPT-4) can achieve expert-level performance on the ENAM, outperforming most of our examinees. We found fair agreement between both GPT-3.5 and GPT-4. Incorrect answers were associated with the difficulty of questions, which may resemble human performance. Furthermore, by reinputting questions that initially received incorrect answers with different prompts containing additional roles and context, ChatGPT achieved improved accuracy.

Published: April 2023

Background. Data from numerous studies indicate a significant prevalence of vitamin D deficiency in Ukraine and the world. In recent years, the Ukrainian medical community has faced two important challenges — the COVID-19 pandemic and the russian aggression, which significantly affected the organization and availability of medical care. Despite the previous epidemiological studies in Ukraine devoted to the vitamin D status, there are no data during the past 5 years that became the background for this research. The purpose was to analyze the vitamin D status in the adult population of Ukraine during the COVID-19 pandemic and russian aggression. Materials and methods. Data of the serum level of 25-hydroxyvitamin D (25(OH)D) in 5029 adults aged 20–99 years, who for various reasons applied for its measurement, were retrospectively analyzed. The analysis was performed depending on the year and month of observation, the age and gender of the subjects, and the 25(OH)D level. Results. The mean serum level of 25(OH)D in the total group was 33.2 [24.1–43.8] ng/ml. The assessment of the number of 25(OH)D tests for 2018–2022 did not reveal any significant differences in 2018 and 2019 but established a significant decrease during the russian aggression in Ukraine in 2022 (by 55.7%) compared to 2018, as well as indices during the COVID-19 pandemic (by 21.6 % compared to 2020, by 23.5 % in 2021). During the observation period, it was established a decrease in the vitamin D deficiency proportion from 20.6 % in 2018 to 9.3 % in 2022, and an increase in the proportion of subjects with suboptimal (from 6.6 to 11.4 %, respectively) and high serum concentrations of 25(OH)D (from 2.2 to 12.7 %). Conclusions. Our results indicate a grown serum 25(OH)D level during 2020–2022 in the adult population of Ukraine compared to the indices of previous years and a decreased share of vitamin D deficiency in the Ukrainian population. In addition, a decrease in the number of 25(OH)D level tests was established, especially during the period of the russian aggression, which should be taken into account during the planning measures to optimize the vitamin D status in the adult population of Ukraine.
The role of regulatory micro-RNAs in inflammatory processes and production of tumor necrosis factor-alpha in patients with rheumatoid arthritis

Published: April 2023

Background. Micro-RNAs are fundamental agents of post-transcriptional control of gene expression. In recent years many works have appeared on the possible role of micro-RNAs in rheumatoid arthritis (RA). Studies of the role of micro-RNA and the relationship with the synthesis of tumor necrosis factor-α (TNF-α) are very promising for understanding the pathogenesis and treatment of RA and other autoimmune diseases. The purpose of the research was to study the role of regulatory micro-RNAs in inflammatory processes and the possible connection with the production of TNF-α in patients with RA. Materials and methods. 29 patients with active RA and 20 healthy individuals (control) were examined. All subjects were examined for 16 micro-RNAs. The choice of micro-RNA was based on previous studies and theoretical conclusions (according to the miRWalk database). Rheumatoid factor, the level of antibodies to cyclic peptides containing citrulline, C-reactive protein (СRP), levels of TNF-α (serum, spontaneous, and stimulated) were determined in the blood of patients. Results. Statistical analysis demonstrated significant overexpression of miR-221, miR-203, miR-146b, miR-132, miR-21 and miR-17-3p and inhibition of miR-223 synthesis in RA patients. The activation of TNF-α synthesis at rest and the increased production of TNF-α by mononuclear cells after stimulation in RA were shown. Differences in the levels of relative expression of some micro-RNAs between seropositive and seronegative groups of RA patients were found, but only hyperexpression of miR-155 was highly reliable. For the first time, a possible relationship between TNF-α production and miR-29 and miR-155 micro-RNAs, as well as a correlation between miR-16, miR-99b and miR-203 and CRP levels, was revealed. Conclusions. The obtained data on the profile of micro-RNAs in RA makes it possible to distinguish the most “interesting” micro-RNAs for further study of pathogenesis, their role in inflammation, to study the choice of TNF-α inhibitors, and predicting the effectiveness of that treatment.

Background. Conducting clinical studies to determine the factors determining the aseptic instability of knee joint endoprosthesis components is an urgent issue in modern orthopedics. The aim of the study was to determine some clinical factors of aseptic instability of knee joint endoprosthesis components. Materials and methods. Comprehensive research was conducted on 285 patients who underwent primary knee arthroplasty between 2010 and 2021, including 85 patients with clinical and radiological signs of aseptic instability of knee arthroplasty components (AIKAC). Also, 200 patients made up a control group with no signs of AIKAC instability observed. Clinical research methods included general, and special orthopedic methods of studying local changes in the knee joint. They included measurement of body mass index (BMI), overloading of the knee joint due to work, previous surgical interventions and early postoperative complications of primary arthroplasty, and presence of angular deformities in the knee joint. For the clinical assessment of the knee joint of patients after knee arthroplasty, we used our own point assessment of the state of the knee joint. Results. It was determined that significant factors for the development of instability of components of the knee joint endoprosthesis are both directly related to the patient (increase in BMI, difficult working conditions, the presence of operative interventions on the knee joint), and factors related to errors during the primary total arthroplasty (residual deformities of the knee joint and early postoperative complications). Conclusions. We determined important factors of aseptic instability of the knee joint in the patients after arthroplasty. Taking into account the results of this study will improve the diagnosis and treatment of aseptic instability of the knee joint.

Published: April 2023

Background. It is well known that chronic kidney disease (CKD) patients develop mineral and bone disturbances which lead to the development of renal osteodystrophy and its complications. Secondary hyperthyroidism is the main reason for the development of mineral and bone disoders in these patients. The purpose of the study was to evaluate the efficacy of combined therapy with Alfacalcidol and Quercetin in the treatment of secondary hyperthyroidism in pre-dialysis CKD patients. Materials and methods. 61 patients with CKD 3 and 4 stages aged 20–78 years were included in the study. Patients were divided into 2 groups: 35 patients received combined treatment with Alfacalcidol and Quercetin granules, and 26 patients received standard treatment with calcium carbonate. Indices of calcium, phosphorus, magnesium, and alkaline phosphatase were analyzed by photocolometry method and parathyroid hormone (PTH) by immune assay method. Statistical analysis was performed in the Statistica 5.0 program (StatSoft Inc., USA). Results. It was shown that intake of Alfacalcidol (0,25–0,5 mcg daily) and Quercetin granules 1.0 g three times per day provided normalization of calcium-phosphorous homeostasis, correction of hyperthyroidism but also has pronounced analgesic effect as compared with patients receiving monotherapy with calcium carbonate. Conclusions. Combined treatment with Alfacalcidol and Quercetin granules in predialysis CKD patients with secondary hyperthyroidism leads to calcium and phosphorus metabolism normalization, correction of secondary hyperthyroidism, and has an analgesic effect.
The positive effect of JAK inhibitor tofacitinib in the treatment of primary Sjögren’s syndrome: a clinical case
Authors: Rekalov D.G. , Daniuk I.O.
Published: April 2023

Primary Sjögren’s syndrome (pSS, Sjögren’s disease) is a systemic autoimmune disease which develops in previously healthy individuals and characterized by damage to exocrine glands, mainly lacrimal and salivary glands, with gradual formation of their secretory insufficiency and various systemic manifestations. According to EULAR recommendation (2019) therapeutic management of pSS bases on symptomatic treatment of sicca syndrome and broad-spectrum immunosuppression for systemic manifestations. The perspective group for the treatment of autoimmune disease is Janus kinase inhibitors, which can block the signals from biologically active molecules (interferons, erythropoietins and cytokines) and providing a response to these target cell signals. Therefore, the use of JAK inhibitors in patients with pSS requires clinical confirmation of effectiveness. The article described the clinical case of the positive effect of tofacitinib with methotrexate combination in the treatment of patient with pSS. A 55-year-old female with sicca syndrome (confirmed by Schirmer’s test), arthralgia, low-grade fever, weight loss and a positive test for the detection of specific antibodies (SS-A/Ro > 240 units/ml, SS-B/La 94 units/ml) was diagnosed with pSS. The total score of EULAR Sjögren’s syndrome disease activity index (ESSDAI) was 9 (activity grade II). The treatment included symptomatic methods of sicca syndrome correcting (replacement therapy with artificial tear preparations and chewing gums with xylitol) in combination with immunosuppressive therapy. The addition of tofacitinib 5 mg twice daily to methotrexate (10 mg weekly) has been shown to significantly reduce disease activity after 6 months of treatment (ESSDAI = 0).
The Relationship between Age and Growth Rate of Wages and the Gender Wage Gap in the Financial Sector in China
Authors: Chen Kexin
Published: April 2023

Using CGSS data, this paper explores the relationship between age and wage growth rates in China’s financial sector by developing a fixed effects model. I find that the wage growth rate declines slowly with age, although the absolute value of wages has been rising. After a brief comparison of the financial sector, the information technology sector, and agriculture, I find that the pattern of their wage growth rates is similar, i.e., the wage growth rate declines slowly with age. Then, through empirical tests, I find that a gender wage gap does exist in the finance industry and that the gender wage gap gradually increases with age. Based on this, I further investigate the relationship between the age of female workers and the wage growth rate, and the possible reasons why the wages of female workers are lower than those of male workers. I find that the wage growth rate of female workers also gradually decreases as their age increases. Moreover, having children has a significant negative effect on the wage growth rate, but the marital status does not.

Published: April 2023

Las emisiones antropogénicas de gases de efecto invernadero están causando un calentamiento del océano que tiene graves consecuencias para la biodiversidad marina. Entre las especies más vulnerables al cambio climático se encuentra la ballena jorobada, cuyas poblaciones se distribuyen en todos los océanos del mundo y realiza migraciones desde las zonas polares y templadas, donde se alimenta, hasta las áreas tropicales, donde se reproduce. El cambio climático ha alterado la disponibilidad de las presas de la ballena, provocando cambios en la duración de sus migraciones, su distribución, su estado de salud y su reproducción. Como resultado, algunas poblaciones de esta especie se encuentran En Peligro, aunque aún se conoce poco sobre los efectos precisos del cambio climático en su ecología y su población. Para abordar esta problemática, es necesario llevar a cabo estudios interdisciplinarios que permitan obtener información sobre la ballena jorobada desde diferentes perspectivas, a fin de construir estrategias de mitigación que estén alineadas con el enfoque de Una Salud y los Objetivos de Desarrollo Sostenible (ods).
El parque como cura de la ecoansiedad
Authors: Hinojosa Hinojosa Karen , Casillas Zapata Amanda Melissa
Published: April 2023

La ecoansiedad es un impacto psicológico a la salud derivado del cambio climático. Sus efectos se dan de formas diferenciadas en poblaciones vulnerables. Es importante conocer estrategias de mitigación para avanzar hacia un mundo con mayor justicia climática. Entre ellas están los parques y áreas verdes en las ciudades, pues, por una parte, mitigan el cambio climático al reducir las temperaturas, captar agua de lluvia y fomentar la biodiversidad; por otra, propician la relajación, reducen la ansiedad, favorecen la salud mental, educan sobre la naturaleza local y contribuyen a la construcción de redes locales. El parque en sí mismo ofrece oportunidades valiosas: a la población, para restablecer su salud física y mental, y al medio ambiente, de saneamiento y regulación. A pesar de los múltiples beneficios de la acción climática en los parques, existe cierta renuencia debido a que los esfuerzos de escala reducida pocas veces son percibidos como una contribución a gran escala, a pesar de que sí pueden sumar de forma colectiva entre toda la sociedad.

Las regiones biogeográficas están definidas por especies endémicas o características, así como por rasgos fisiográficos particulares. La delimitación geográfica y florística de la provincia Depresión del Balsas (México) y sus biomas se llevó a cabo a partir del uso de capas cartográficas (subcuencas y elevación) y de registros de herbario de las plantas vasculares presentes en la región. La Depresión del Balsas tiene una extensión de 115,007 km2. El bosque tropical estacionalmente seco constituye el bioma con mayor superficie (74,548 km2) y se registra desde el nivel del mar hasta los 1,627 m. Utilizando a las plantas vasculares como objeto de estudio, la circunscripción de los biomas con base en un análisis biogeográfico reveló la existencia de 10 grupos florísticos (fitocorias), los biomas más relevantes fueron los bosques tropicales estacionalmente secos y los bosques templados. Esta delimitación y regionalización, tanto fisiográfica como florística, permitió proponer una estrategia metodológica que puede ser de utilidad para definir límites geográficos en otras áreas de interés.

Abstract: The population's life expectancy is a problem for the government or pertinent agency of a particular nation. A statistical measurement of the anticipated average lifespan of an organism is life expectancy. Data for the appropriate nation, including all required fields, must be gathered in order for the department to handle life expectancy in an efficient manner. This study analyses and forecasts trends in life expectancy using data analytics and machine learning approaches. Regression models are used in the study to find the major determinants of life expectancy as well as descriptive statistics to understand how long people live across various population groupings. The WHO data repository was used to gather the information, which was then retrieved from the Kaggle website, a reputable data science resource. The dataset contains variables including vaccination, mortality, economy, social factors, and other health-related variables. It covers the years 2000 to 2015 for 193 nations. These factors are taken into account when this study uses data analytics and machine learning to implement life expectancy. After examining numerous regression methods, the Random Forest Regressor was chosen since it generated the greatest accuracy among the models studied.

Abstract: Recently, security has been a growing concern for human life, and the cost is a significant concern. The research recommends implementing a real-time recognition system to rapidly handle photographs to reduce monitoring expenses and ensure safety in homes and offices by identifying people. The main goal of this study was to create an intelligent face recognition approach using deep learning for intelligent homes. To illustrate the study's effectiveness, the suggested model is contrasted with other cutting-edge techniques. The research introduces a tree-based deep model for facial recognition in the Cloud, which requires fewer computing resources but maintains accuracy. The input volume of the model is partitioned into multiple volumes, and trees are created for each volume according to their height and number of branches. A residual function, constructed from a convolutional layer and two non-linear functions, represents each branch. The proposed model is assessed on various publicly accessible databases and compared with the industry's best deep models for facial recognition.

Abstract: The sequence of excrescence of cancercontrols thousands of inheritable mutations. Now the most grueling task is to separate between the mutations which will further contribute to cancer growth and mutations. Interpretation of inheritable mutations ismanually done presently, which consumes a lot of time and may also lead to a squishy opinion that isn't tolerable in the healthcare sector. Clinical molecular biologists have to manually review textbook substantiation of clinical exploration literature for every singleinheritable mutation. Machine Learning (ML)helps in the precise and fast opinion of acomplaint and leads to effective decision- making. Once the excrescence is detected wego for testing whether it's cancerous or noncancerous. However, it goes for a gene panel test which takes a much longer time which is 3- 4 weeks, So using the patient’s former medical records and using a vivisection report we're detecting for which gene he/she is positive, If set up to be cancerous. Using our ML model we will helpcases in early diagnosing which will also helpCroaker to go with the following treatment. Ittakes so long time for generating the gene panel cancer report roughly 3- 4 weeks. In these 14 days period cancer excrescence can surpass stage 3 orstage 4 which is veritablyparlous and occasionally may indeed lead to death. Using colorful machine literacy models and after resolving all business constraints this process will be done as soon as possible.

Penyuluhan Hukum Masyarakat tentang Perjanjian Pengikatan Jual Beli
Authors: Hidayat Putri Zora Febriena Dwithia
Published: April 2023

Idealnya, transaksi jual beli tanah dilakukan dengan membuat AJB melalui PPAT dengan terlebih dahulu memenuhi syarat-syarat yang telah ditentukan berkaitan dengan itu. Prakteknya, banyak jual beli yang tidak bisa seketika itu juga dibuatkan AJB oleh PPAT karena terdapat persyaratan yang belum dipenuhi oleh salah satu atau bahkan kedua pihak. Sebagai terobosan untuk mengatasi persoalan tersebut terdapat instrumen yang dapat digunakan yakni dengan membuat Perjanjian Pengikatan Jual Beli (PPJB) yang berfungsi sebagai pengikat atau tanda jadi atas jual beli sembari memberikan waktu bagi para pihak untuk memenuhi segala persyaratan yang ada. Nyatanya, banyak masyarakat yang masih belum memiliki pemahaman yang baik terkait seluk beluk pertanahan, khususnya terkait konsepsi PPJB serta wujud perlindungan hukum yang diberikan bagi para pihak dalam PPJB. Metode yang digunakan dalam kegiatan pengabdian ini adalah dengan melakukan penyuluhan hukum yang bertujuan meningkatkan pengetahuan dan pemahaman masyarakat terkait PPJB. Kesimpulan yang didapatkan adalah bahwa pengetahuan hukum masyarakat terkait terkait PPJB masih perlu ditingkatkan lagi baik melalui penyuluhan hukum semacam ini, sosialisasi dari pemerintah baik terkait jual beli tanah, PPJB, maupun peran dan fungsi PPAT agar perlindungan hukum yang telah disediakan bagi masyarakat dapat dioptimalkan.
 
Community Legal Counseling on Sale and Purchase Binding Agreements.
Ideally, land sale and purchase transactions are carried out by making AJB through PPAT by fulfilling certain conditions first. Practically, many transactions cannot be made immediately by PPAT because there are requirements that cannot be met by one or even both parties. As a breakthrough to overcome this problem, there is an instrument that can be used: ‘Sale and Purchase Binding Agreement’ (PPJB) which functions as a binder for the sale and purchase while giving time for the parties to fulfill all existing requirements. In fact, many people still do not have a good understanding in the land sector, especially regarding the conception of PPJB and the form of legal protection provided for the parties in PPJB. The method used in this service activity is to conduct legal counseling which aims to increase knowledge and understanding of the community regarding PPJB. The conclusion obtained is that the community's legal knowledge related to PPJB still needs to be improved either through this kind of legal counseling, socialization from the government regarding land sale and purchase, PPJB, as well as the role and function of PPAT so that the legal protection that has been provided for the community can be optimized.

Community service in the form of socialization and legal counseling carried out in Tanah Tinggi Village, Tangerang City is to find out the implementation of laws related to new narcotics crimes that have not been regulated in Law Number 35 of 2009 about Narcotics and the development of new types of narcotics in Indonesia. In this community service, socialization and discussion methods are used to provide an overview of the absence of legal norms regarding new types of narcotics. So that the results obtained in this community service are the implementation of the law against a new type of narcotic crime because it is not contained in the legislation in Indonesia. The implementation of the law can be used with alternative interpretations from the judges. The interpretation here is used as a legal need and a sense of justice that is embraced in Indonesian society. From the interpretation and looking at the judge's decision, Methylone is a harmful substance and can be reached with the provisions obtained in the Narcotics Law, for its abuse it can be held legally responsible without putting aside legal certainty and the principle of legality.

This paper aims to discuss Indonesia's current legal framework of citizenship following its more pervasive demand to adopt dual citizenship. It argues that several issues regarding citizenship law in Indonesia have been relatively problematic, mainly related to the change of citizenship status contentiously experienced by Arcandra Tahar, Gloria Natapraja, and Djoko Tjandra to the increasing demand for dual citizenship. On the other hand, in this context, Indonesia's diasporas have voiced this interest in legal reform, resulting in more flexible opportunities and supporting transboundary businesses, as they have encountered some challenges due to restricted citizenship regulations. Using legal research, this study showed that citizenship had become a strategic issue with far-reaching implications. While Indonesia adopts a limited scale of dual citizenship and the vigour for dual citizenship has increased, the flexibility over dual citizenship requires further study of national security and citizens' loyalty to Indonesia. This paper suggested in adopting India’s OCI model for Indonesia’s citizenship policies as ample opportunities for this country’s citizens with foreign status to continue enjoying and accessing their rights in Indonesia, except in the political field. This measure subsequently would be a step forward to adapt citizenship regulations to globalisation while still paying attention to the nationalism concern.
Uso de materiales ligeros para la producción de hormigón de baja densidad: una revisión literaria

Published: April 2023

Throughout the 20th century, the construction industry has been using large quantities of concrete. Consequently, the demand for natural aggregates has increased, making it necessary to counteract their use. In this context, this work aims at presenting a literature review of the use of lightweight materials to produce low-density concrete, whose thermal insulation is mainly made using lightweight aggregates. In this framework, 52 articles indexed between 2017 and 2021 in the Scopus database were reviewed. The results revealed that, by employing ceramsite sludge as an aggregate, a density of 1,251 kg/m3 can be obtained and, with expanded clay aggregates, compressive strengths from 17.7 to 66.1 MPa can be obtained. In conclusion, it was determined that the use of lightweight materials in concrete production can reduce its density, in addition to contributing to the reduction of environmental damage.
Optimización multiobjetivo de la eficiencia energética y el confort térmico en edificios de oficina públicos. Periodo crítico de verano en la ciudad de San Juan, Argentina

Published: April 2023

Buildings represent 40% of the world's energy demand and CO2 emissions. In Argentina, buildings are responsible for 40% of the total annual energy consumption. The problem lies in an imbalance between the need to provide a high quality of life and comfort in office spaces, and the high energy cost required to meet that goal. Both a high comfort level and energy savings represent two objectives to be achieved. In this sense, this paper proposes a new methodology that combines onsite measurement with mathematical simulation tools. Innovative techniques and models are incorporated to make the tool, applying thermal-energy multi-objective optimization, which operates dynamically during working hours. The results show significant savings in energy consumption regarding cooling office spaces in the summer, from 57.5% to 83.3%, together with an increase in the thermal comfort quality, with improvements between 4.7% and 29.4%.
TIME ANALYSIS OF A CONSTRUCTIVELY NONLINEAR SYSTEM WITH ONE-WAY CONNECTIONS
Authors: Potapov Alexander , Tazeev Nail
Published: April 2023

An active method of suppressing wind auto-oscillations of an overground gas pipeline model is considered, which allows the system to be tuned from the resonant frequency by changing its design scheme with the help of a vibration damping device operating on the principle of one-way con-nection (OWC). A new mathematical model of vibrations with a symmetric form of natural vibrations of the system is proposed. Variants of vibration models with one and two OWC, located in the central span of the design scheme of the gas pipeline, are considered. The implementation of a non-stationary dynam-ic process is carried out within the framework of the theory of temporal analysis for a model of an over-ground gas pipeline in the form of a multi-span continuous beam with point masses located in the design sections of the model. The equation of motion is presented in the matrix form of the Duhamel integral, taking into account internal friction, which follows the disproportionate damping model. Computer simu-lation of the problem for a system with 39 degrees of freedom is carried out. The kinematic and force pa-rameters of the dynamic response of the dissipative system are obtained, a comparative analysis of the proposed oscillation model for the design models with one and two OWC is given, and the efficiency of the model with two OWC is shown.

Published: April 2023

The article deals with the problem of preserving and developing the language as an object of small nations cultural heritage on the example of Abkhazia. The relevance of the work is due to the understanding of transculturalism and translinguism phenomenon as a resource for the possible salvation and development of an endangered language. The purpose of the article is to determine the vector of preservation and development of the Abkhaz language. The subject of the study is the ethno-cultural features of the Abkhaz language, as well as understanding the role and place of the phenomena of translinguism and transculturalism in its preservation and development. The methodological basis of the work is a cultural approach that requires the analysis of social phenomena through the prism of such categories as language, traditions, values. As a result, authors determined linguo- and ethno-cultural features of the Abkhaz language; indicated the vector of its preservation and development, which will determine the worthy place of the national language in the “mixed” socio-cultural discourse. In the conclusions, the authors conclude that the processes of translinguism and transculturalism play a significant role in the preservation of the Abkhaz language and ethnocultural heritage in the era of a clear contradiction between globalism and the desire to express local identity.
