On Kuzian suite of the Marmarosh nappe of the Ukrainian Carpathians
Authors: Shlapinsky Volodymyr , Ternavsky Myroslav
Published: June 2023

In 1957, L. G. Tkachuk and D. V. Gurzhiy have singled out the Upper Paleozoic Kuzian suite in the north-western part of the Marmarosh crystalline massif at the Rachiv area. It consists of phyllites, limestones, quartzites and dolomites. The suite is widely distributed in the Dilovets subcover of the Marmarosh nappe at the Rakhiv and Chyvchynian areas. There are two alternative points of view upon the age of the Kuzian suite. Some geologists attribute it to Paleozoic time (Upper Devonian-Lower Carboniferous), the others attribute its lower part to the Upper Paleozoic, and the upper one: to Triassic. One can notice the existence of the different estimation of the lithological composition and different estimation of the lithological composition and the volume of the Kuzian suite.Thus, in 1970 A. K. Boiko has devided it into Muntselulska (Lower) phyllite-quartzite one of Paleozoic age and Upper (Triassic) phyllite-carbonate one for which he saved the name Kuzian suite. The important is that a stratigraphic interruption was fixed between the above-mentioned units. The phyllite-carbonate Kuzian suite is dated on the basis of transgressive occurrence of the middle Triassic dolomites on it, discovery of the post-Paleozoic mosses in its lower part at the Soimul Mountain, and in the upper one: the complex of spores and pollen of Mesozoic age. Geologists, that do not recognize the idea of belonging of the part of suite to Mesozoic, indicate the next contradiction. If we accept the Mesozoic age of the Kuzian suite, so we must affirm that carbonate series of Middle Triassic-Jurassic were deposited on the massif at the same time, and 5–8 km southerly, the regional metamorphism of the Kuzian suite occurred within that zone (by the way, according to some facts at an interval of 148–178 and 175–181 mln years, and according to another information: at an interval of 196–221 mln years. This remark is not correct because the age of the Kuzian suite is Lower Triassic (251.9–247.2 mln years), but metamorphism occurred much later. In those sections where the Kuzian suite lies on the Muntselulska one, basal conglomerates consisting of pebbles and quartzitic fragments of underling suite are present in its bottom. Rocks of the Muntselulska and Kuzian suite are similar by their metamorphism intensity. For the Mesozoic Kuzian suite the manifestations of the main magmatism are characteristic, unlike the Upper Paleozoic acids. The facts testify to that the Mesozoic Kusian suite is existing, but there is a certain indefinity as to its finer dividing, stratigraphic volume and correlation with deposits of Middle Triassic. To avoid confusion, it is expedient to alter the name of the Mesozoic Kuzian suite and to name it, for example, Neo-Kuzian.

An analysis was made as to the usage of geological-geophysical methods for studying of low-amplitude tectonic dislocations in coal-enclosing massifs. As a result of geophysical researches conducted at coal fields, mine fields and mine workings of the Lviv-Volyn Coal Basin, the methods of field observations by means of natural electromagnetic and electric fields were worked and their results were processed for prediction and diagnostics of tectonic dislocations with a break of continuity and zones of unstressed state. To raise the efficiency of the methods of electromagnetic fields it is recommended to carry out measurements at wide frequency range (from 5 to 50 hz) with orientation of the antenna according to the world sides (azimuthal surveying) and at narrow frequency range (5; 12.5; 17 khz) with the southern orientation of the antenna (frequency sensing). According to azimuthal surveying one can calculate the vector of maximum intensity of electromagnetic radiation. It was ascertained that over distinctive dislocation one can observe the variation in the direction and absolute value of vectors. Displacement of the anomaly of electromagnetic radiation intensity at different frequency range by profile indicates the direction of dipping of the area of displacement of dislocations with a break of continuity. The method of natural electromagnetic impulse field of the Earth fixes both the dislocations, distinguishes by geological-geophysical methods before, and new low-amplitude dislocations and stressed zones.Tectonic dislocations, that are displayed only in Paleozoic deposits, are distinguished by contrast anomalies of electromagnetic radiation in electromagnetic field, but dislocations with a break of continuity that cut the Mesozoic thickness and in most cases are accompanied by zones of rock fracturing in the Cretaceous deposits: by wide destructive anomalies. Plots over worked-out lavas with stressed deformational state are characterized by strongly differential abnormal values of the intensity of natural impulse electromagnetic field of the Earth. The method of natural electric field allows us to detect zones with water-bearing fracturing rocks in the upper part of the geological section. Methods of natural impulse electromagnetic field of the Earth and natural electric field may be used both independently and in the complex with other geophysical methods for detection and tracing of tectonic dislocations and dynamically-unstressed zones. Thus, the optimum apparatus-methodical complex for detection and diagnostics of low-amplitude dislocations with a break of continuity of coal-enclosing series by electromagnetic methods (NIEMF, NEF) was formed and effective methods of field observations, processinf and interpretation of data were developed.
Specific Character of the Folklore Translation: After the Material of Hungarian and Slavic Languages
Authors: Mushketyk Lesia
Published: June 2023

The translation of fiction and folklore works has its own specific character. It covers poetry and prose, lyrics and drama. Modern translators use the advice and creative heritage of their predecessors, in particular Maksym Rylskyi, who has combined scientific and folkloristic activities with translation from Slavic and non-Slavic languages, made a number of valuable comments on the issues of translation, its adequacy, transmission of the national identity of works, etc. Attention of the other translators and researchers has been also drawn to the issue of the translation of folklore works into Hungarian and Ukrainian. É. Grigássy, Zs. Rab, I. Petrovtsii and others are among them. They testify that besides the language competence, this work requires certain extralinguistic knowledge of ethnology, history, local studies, etc. They talk about two main dangers in such translations: on the one hand, it is the leveling of the national flavor of the work, its transformation into one’s own work; on the other hand, the text should not sound foreign, but should be natural and easy to read. The translation of various genres and types of folklore has its own specificity. Thus, significant difficulties arise when translating the Slavic heroic epos into Hungarian, the volumetric form of dumy and byliny, their epicness, dynamism, etc. Reproduction of the flavor of folk songs is demonstrated in the article exemplified by the translations of Hungarian calendar and love songs into Ukrainian. Then the authoress presents a number of samples of her own translations from the bilingual collection Hungarian Folk Fairy Tales of Uncommon Beauty, commenting the transmission of realia, proper names, phraseological units, language formulas – initial, medial and final. Despite certain doubts about the ability to translate folklore works into very different (not close) languages successfully, it can be said with certainty that it is possible, but this process requires, in addition to deep linguistic and discourse knowledge, extralinguistic, as well as poetic skill and talent of the translator.
Cooperation between the Museum of Sloboda Ukraine and the Ethnology and Local History Section of the Kharkiv Research Department of the History of Ukrainian Culture (1920s)
Authors: Stadnik Yuliia
Published: June 2023

The article investigates the collaboration, at personal, scientific, and public levels, between the Ethnology and Local History Section of the Kharkiv Research Department of the History of Ukrainian Culture and the Museum of Sloboda Ukraine throughout the 1920s. This period saw the development of Ukrainian science under challenging socio-political circumstances. Insufficient financial support, the restructuring of the education and science system, and later, the repression of scholars created an unstable scientific field. At the same time, the cooperation of scholars within ideological and thematic schools of thought intensified. The research determined that the joint activities of the staff of the Ethnology and Local History Section and the Museum of Sloboda Ukraine were based on common research topics, as well as the work of talented scholars, including M. Sumtsov, R. Dankivska, I. Yerofeyev, P. Kovalivskyi and others in full-time positions simultaneously in both institutions. In addition, the museum was considered one of the Department’s scientific and auxiliary institutions. The study found that personal connections within the Section and the Museum led to the formation of a professional circle of scholars who tackled theoretical and practical problems of ethnology and local history. The joint activities resulted in the development of ethnological research programmes used during search expeditions, as well as in the partial solution of the problem of promulgating the results of scientific work – the publication of scholars’ achievements in the Museum’s editions of and the Department’s collections. The department also trained a younger generation of scholars who engaged in professional activities in the museum industry. Joint efforts of staff of the Department and the Museum were instrumental in carrying out successful cultural and educational work. From 1925 to 1927, a series of lectures on the history and culture of Ukraine was organized. As a result of mutual assistance, the Ethnological and Local History Section of the Kharkiv Research Department of the History of Ukrainian Culture and the Museum of Sloboda Ukraine became centres of ethnological and local history studies in 1920s Kharkivshchyna.

The development of distributed generation in Ukraine corresponds to global trends in the energy sector. The particular relevance of distributed energy for Ukraine lies in the fact that its development contributes to reducing the costs of energy consumers, reducing the load on energy networks and losses of electrical energy, as well as improving the reliability of the energy system and energy efficiency of the economy. This article provides an overview of the main sources, technologies, and trends in the development of distributed generation (DG) in Ukraine, including stations running on biofuels (biomass and biogas), small hydroelectric power stations, as well as distributed solar and wind power plants. Various aspects related to the current state and future prospects of distributed energy in Ukraine are considered, with particular attention to barriers that impede its development. The main operating modes of distributed generation facilities are identified together with the National Energy Company of Ukraine. An analysis of the structure of distributed generation facilities by technology and power usage is carried out using statistical data. The factors that stimulate the development of distributed generation technologies are identified, and examples of successful implementation of DG facilities in Ukraine are provided. The main expected effects of implementing DG are determined, such as the adaptation of consumers to the uncertainty of the state of electricity due to the armed aggression of the Russian Federation, increasing the reliability of power supply, partial unloading of both main and distribution power lines, reducing energy losses in networks, as well as providing opportunities for communities to meet their energy needs. In addition, the development of distributed generation can contribute to increasing the level of competition in the electricity market, stimulating the review and optimization of pricing strategies. Keywords: distributed generation, RES, local networks, decentralization of energy supply.
“Vinieron los milicos… pero nunca pasó nada”.
Authors: Robertini Camillo
Published: June 2023

La experiencia del mundo del trabajo bajo la última dictadura cívico-militar ha representado un imprescindible tema de debate de la historiografía argentina. Los estudios, sin embargo, han dado cuenta casi exclusivamente de la experiencia obrera vinculada a la militancia gremial-clasista y, en consecuencia, a la represión sufrida por los trabajadores desaparecidos. Este ensayo propone el estudio de la experiencia del llamado “obrero común” bajo dictadura. Lejos de las narraciones conflictivas y opositoras, el caso que se ilustra da cuenta de las formas que configuran la “aceptación cultural” tanto del gobierno autoritario cuanto el repudio hacia el mundo de la militancia clasista y guerrillera. A través del análisis de fuentes orales se reconstruye el imaginario, la memoria y la historia de aquel sector obrero que aceptó y convivió con la dictadura. El ensayo analiza el caso de la comunidad obrera de la Fiat Concord.

Authors: Mata Boschini Laura Paola , Bonilla López Marisela
Published: June 2023

The present exploratory study sought to identify the attitudes towards reading for pleasure of a group of fourth year English as a Foreign Language (EFL) majors after taking mandatory literature courses. A total of 45 students from the School of Modern Languages at a public university in San José, Costa Rica participated in this investigation. In order to elicit the participants’ attitudes and motivations both before and after entering the university, an online survey was administered. The results of the survey showed that after entering the university almost half of the participants kept good reading habits, apart from the mandatory readings. Main findings also reveal that the main pre-university reading motivators suffered a change after entering the university. Although personal enjoyment and relaxation were maintained, motivators related to the general improvement of language skills obtained a higher relevance for the students. The survey answers also suggested the literary works read in class play an important role in the students’ voluntary reading practices. Practical implications are discussed.

Published: June 2023

Technology is used to keep track of things and timing and make the best decision on the information available. Project Management (PM) has to offer through its various software and technical tools. PM software has always been compared to the traditional ways of libraries. If a library has always been compared to its traditional ways of doing projects, PM brings systematic strategies to the planned project of libraries from beginning to end. The main objective of this research is to find a systematic literature review on the software of PM, the -advantages of using PM in libraries, and the challenges faced by the libraries using PM. This research used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to illustrate the systematic literature review. The terms “Project Management” and (“library” OR “libraries”) were applied to the advanced research of the five databases: Ebscohost, Emerald, Scopus, WOS, and ScienceDirect were selected databases to ensure relevant studies were captured. The main finding from the research is that using Project Management software in libraries has many advantages, such as clarity of planning and a good understanding of technical tools and software, despite many challenges. It provides end-to-end planning and can be adapted to frequent changes to increase productivity and success. In addition, unlike other studies, this study indicates the missing gap in the literature, and it is hoped that it will guide the researchers.

Objective. To conduct a comparative retrospective analysis of the anatomical and functional results of surgical treatment of proximal humerus fractures AO/OTA 11-B, 11-C using different methods in patients over 50 years old with osteoporosis to justify a differential approach. Methods. The study included 102 patients aged 50 years and older with osteoporosis and proximal humerus fractures AO/OTA 11-B, 11-C. The patients were divided into three groups: I — 50 (16 men, 34 women) whom were performed open reduction and internal fixation (ORIF) with the PHILOS plate; II — 44 (8 men, 36 women) — ORIF with the PHILOS plate and using 3D polylactide (PLA) porous implants were applied; III — 8 (2 men, 6 women) whom were performed primary reversed total shoulder arthroplasty (RTSA) with developed total reversible endoprosthesis. The results of treatment were evaluated according to the Constant-Murley Shoulder Score system after 3, 6, 12 months. The results. Positive results in the first group were obtained in 72.0 % of patients (the average Constant-Murley Shoulder Score after 12 months was 78.4 points); in the second — in 81.8 % (88.0 points); in the third — 75.0 % (82.0 points). A differentiated approach to the choice of surgical treatment of patients aged 50 years and older with fractures AO/OTA 11-B, 11-C is proposed. The clinical trial of the reverse total modular shoulder endoprosthesis developed by us using porous 3D titanium parts, manufactured by additive technologies, showed positive short-term results. The design features of the device increase the reliability and durability of proposed endoprosthesis. Conclusions. RTSA in the case of unstable proximal humerus fracture or in the case of metal structure migration after primary ORIF in patients with low bone mineral density is the effective surgical intervention that allows to achieve satisfactory functional results in up to 3 years.

Knee joints injury in rheumatoid arthritis patients appear in 70 % cases. This is the most common cause of loss of work capacity, the ability to self-care. Patients become severely disabled, in that the disease is accompanied by deformations with the development of discordant positions of the lower limbs, which lead to a partial or complete loss of the function of support and walking, so this problem needs to be studied.  Objective. To make an analysis of orthopedic treatment of secondary arthrosis of knee joints in RA patients, complicated by deformities depending on the age and gender of the patient, stage, duration of the disease and activity of the inflammatory process. Methods. In this work we have analyzed the orthopedic treatment of 66 RA patients with secondary arthrosis with axial deformities, who underwent 75 total endoprosthetics between 2013 and 2020. Anamnestic data, clinical, biomechanical and statistical research methods were used. The obtained data were evaluated using the scale of Joseph J., Kaufman E. E. Results. The analysis of the results of knee joint replacement was followed in the period from 6 months to 5 years. The results were carried out according to the 100-point scale Joseph J., Kaufman E. E. (1990). Thus, the analysis of the results of total knee arthroplasty in patients with RA according to the scale of Joseph J., Kaufman E. E. showed that good results were obtained in 46 (79.31 %) patients, satisfactory results in 11 (18.97 %) and unsatisfactory results obtained in 1 (1.72 %) patients. The reliable relationship of the level of joint deformation with the level of disease activity and with the scale of Joseph J., Kaufman E. E. was researched. Other indicators are not reliably correlated with the level of joint deformation. As a result of pairwise comparisons of groups with each other using the Duncan test, a significant increase in the degree of joint deformation was found in the group with activity 3 compared to the group with activity 1. The use of basic or complex therapy does not reliably affect the degree of  joint deformation. Conclusions. Total knee joint replacement need patients with II stage of the 2nd phase of the disease and higher. In our opinion, this is the most optimal time for surgical treatment, which allows patients with RA to fully use the possibilities of an implanted endoprosthesis.

Secondary degenerative disabling changes in the hip joint often develop in the long term after surgical treatment of hip fractures. A well-founded differential approach to the selection of endoprosthesis components and additional means of stabilizing bone fragments is necessary. Objective. To investigate changes in relative deformation values in a hip joint model with a acetabulum fractures 62–B1.3 type by AO/ASIF classification under the conditions of its endoprosthesis using various osteosynthesis options. Methods. A basic finite-element model of the pelvic girdle of a person with a fracture of the bottom of the cruciate ligament type 62-B1.3 (АО/ASIF) was developed, on which 7 variants of endoprosthesis of the left hip joint were modeled: without fracture (1); without osteosynthesis of fragments (2); fixation of a fragment of the acetabulum back wall with two screws (3), two screws and a bone plate (4), two screws and a bone plate with a Jumbo cup implantation (5); 5 case, long screw in the front column (6); option 5, long screws in the front and rear columns (7). Results. When using a large-sized Jumbo cup, the relative deformations of the bone regenerate in the center of the bottom of the KZ were reduced to 1.0 %, regardless of the osteosynthesis option. Around the free fragment of the short circuit, the largest relative deformations (3.0 %) were found in version 5 of the model. The use of long rods in the columns led to decrease in the relative deformations of the bone regenerate around the free fragment of the KZ to 2.0 %. Conclusions. Mathematical models proved that an increase in the number of osteosynthesis tools under the conditions of the total hip endoprosthesis replacement, 62-B1.3 (АО/ASIF) type KZ fracture leads to a decrease in the relative deformations of the bone regenerate along the entire fracture line. The use of a large-sized Jumbo cup makes it possible to reduce the level of relative deformations of the bone regenerate in the cent­ral part of the KZ.

The treatment of patients with tibial fractures and overweight has certain peculiarities due to the increased load on the osteosynthesis device. Objective. To compare the stress-strain state of models of the lower leg with a fracture of the tibia in the upper third of the diaphysis under the influence of torsional load under different options of osteosynthesis depending on the patient's weight. Methods. Using the finite element method, a fracture in the upper third of the tibia and three types of osteosynthesis were modeled: using an external fixation device (EFD), a bone plate, and an intramedullary rod. A torque of 7 Nm and 12 Nm was applied to the tibial plateau. The results. The highest indicators of the stress level in the fracture zone (6.3‒10.8 MPa) and on the metal structure (251.0‒430.2 MPa) were determined in the model with a bony plate. In the model with osteosynthesis with the help of EFD, a fairly low stress level (0.2‒0.3 MPa) was established in the fracture zone, but a high one in the proximal part of the tibia (6.7‒11.5 MPa). The lowest values of stresses in the fracture zone (0.1‒0.2 MPa) and the proximal fragment of the tibia (0.6‒1.0 MPa) were determined under the conditions of reproduction of osteosynthesis using an intramedullary rod, but in the distal part of the tibia the stresses remained quite high — 11.1‒19.0 MPa. Conclusions. The values of stresses in the fracture zone in the models with EFD and intramedullary rod were significantly lower than the values of the intact bone, with the periosteal plate - only at a load of 7 Nm. In the distal fragment of the tibia, the highest stress level was determined in the model with osteosynthesis with an intramedullary rod, in the proximal one — with EFD. Among the metal structures, the greatest stresses were found in the periosteal plate and around the fixing screws and rods under the conditions of its use. The function of the dependence of the amount of stress on the weight of the patient in the elements of the model turned out to be linear and directly proportional.

Venous thromboembolism is one of the serious complications that occurs after total hip arthroplasty (THA). Among the risk factors may be the presence of disorders of hemostasis and fibrinolysis in patients before surgical intervention. The aim of study to identify the influence of hip osteoarthritis  III–IV stages on the hemostasis of patients before performing THA. Methods. A prospective study was conducted with the participation of 60 patients with  hip ostheoarthritis III–IV stages and 30 healthy volunteers (control group). Blood and urine samples were obtained from all participants (in patients — one day before THA). Prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen, fibrinolytic activity (FA), soluble fibrin monomer complexes (SFMCs), glycoproteins, sialic acids, chondroitin sulfates (CS), acid and alkaline phosphatases, β lipoproteins were determined in the blood; in urine — oxyproline, uronic acids, Ca and P. The Pearson correlation coefficient (r) was calculated to determine the relationship between markers of hemostasis and connective tissue metabolism. Results. Compared with the control group, the level of alkaline phosphatase in the blood of patients with hip ostheoarthritis level of glycoproteins (r = 0.97; p < 0.05), cholesterol (r = 0.91; p < 0.05); the level of SFMCs was correlated with the level of glycoproteins (r = 0.99; p < 0.05), CS (r = 0.94; p < 0.05). Conclusions. In patients with hip ostheoarthritis III-IV stages the levels of connective tissue markers (glycoproteins, CS) correlate with the levels of hemostasis markers (fibrinogen, SFMCs). This is of clinical significance for the timely prevention of the development of thromboembolic complications in patients to whom THA is recommended.

Published: June 2023

Objective. To find out the state of the bone threading under the conditions of inserting the rods of different manufacturers and to establish the duration of a stable «rod – bone» connection in treatment of diaphyseal fractures of the bones of the limbs. Methods. An experiment was conducted using tibia bones of calves. Rods used in external fixators of Biomet (France), Stryker (USA), LLC H B Orto (Ukraine), ORTOPAK (Ukraine) manufacturers were selected. The shape of the bone threading and its contact with the surface of the rod were studied at 2‒5X magnification. Devices from the specified manufacturers were used to fix bone fragments during the treatment of gunshot fractures in 91 patients. The stability of the rod in the bone was checked. Results. The experiment showed that in order to obtain the appropriate bone threading, it is necessary to first pass through both layers of the compact bone of the diaphysis using a drill with a diameter that corresponds to the inner diameter of the threaded part of the rod. Without this, bone coils in the first cortical layer are destroyed or bone fragments in the second are chipped off, reducing the strength of fixation. In the case of screwing the rods into the drilled channel in the second layer of the cortical bone, the quality of the «rod – bone» connection was worse in all cases. Under the conditions of installing the rods in the cancellous bone, a larger number of defective turns was formed in it compared to the compact one. The lowest frequency of rod instability in patients was found when using the ORTOPAK device (18 %); it was much more frequent (35– 51 %) when using devices from other manufacturers. The incidence of the unstable state of the rods was almost 4 times greater in their location in the epimetaphysis than in the diaphysis. Conclusions. For the most effective connection of the rod with the bone, it is necessary to screw it into the prepared channel with a diameter that corresponds to the inner diameter of the threaded part of the rod. The quality and duration of the stable state of the rod in the bone depends on the technical characteristics of its threading, localization and state of fusion of the fragments.

In the treatment of victims with gunshot fractures of the long bones of the limbs, important importance is attached to determining the need and conditions for performing conversion (replacing the fixation method) with the formulation of reasoned indications. At the first stage of specialized care, such patients are fitted with external fixators, which provides adequate stabilization and simple wound care. Their conversion at the second stage to intraosseous increases the effectiveness of treatment. The aim: To analyze the results of using a scoring scale to substantiate the replacement of the fracture fixation method in the system of treatment of victims with combat limb injuries. Methods. The medical documentation for the period 2014-2021 was studied. The number of patients with gunshot fractures of long bones was 350, the average age was (36.4 ± 1.42) years. Patients were divided into two groups: the main group (193 wounded) — in the preoperative period, the authorʼs scale «Assessment of the possibility of conversion» was used; comparison (157 people) — point assessment was not performed. Methods. Descriptive, comparative analysis, systematic approach, statistical. The SF36 questionnaire was used to assess patients' quality of life. Results. The analysis of treatment results in the long term (1.2‒1.5 years) showed that the use of the author's scale in the preoperative period and the subsequent treatment made it possible to improve the subjective quality of life indicator by an average of 22.2 %. Conclusions. Justification of the expediency of replacing the fixation method during the treatment of patients with gunshot fractures of long bones using the developed scoring scale makes it possible to avoid unjustified conversion, reduce risks and minimize the occurrence of infectious complications.

The issue of adequate treatment of post-traumatic deformities of long bones has become more urgent due to the large number of injured as a result of combat trauma and the presence of residual displacement of fragments after primary care providing. Objective. On the basis of literature analysis and own clinical experience, present methods of treatment of post-traumatic extra-articular deformity of the distal part of the femur (DF). Methods. The available professional literature, publications in electronic systems Google Scholar, PubMed, ScienceDirect were analyzed. The results of treatment of 38 patients with post-traumatic extra-articular deformities of the DF, in which the fracture line was extended to the area of the joint at the time of the primary injury, were studied. To plan the surgical treatment, the author's 3D-printing technology was used in 12 patients with the most complex cases. A clinical exampleis given. Results. Key moments of patient examination, principles of correction and approaches to its planning in case of DF multiplanar deformities are defined. The results of 3D-visualization and 3D-printing of the damaged segment during the examination and planning of deformity correction were evaluated. All patients to whom the 3D-modeling technique was applied were operated оn, considering the individual characteristics of the deformity.After each stage of surgical treatment, a course of individual rehabilitation treatment was carried out. Positive dynamics of functional results were obtained within 12 months according to SF-36 and AOFAS scales. Conclusions. The use of 3D-modeling during the planning of corrective surgery allows the surgeon to increase the accuracy of the correction and significantly reduce the time of the operation. Well-known and improved methods with individually selected rehabilitation, used for the treatment of post-traumatic extra-articular deformities of the distal femur contribute to faster recovery, avoiding potential complications and achieving positive functional outcome in such patients.

Published: June 2023

Goal. Determining the essence of the index of economic complexity and the feasibility of its use as a tool for assessing the level of development and economic potential of the country. Method. A systematic approach, a deductive method, comparison, grouping, generalization were applied in order to solve these tasks. Results. In this paper, the essence of the economic complexity index and the expediency of its use as evaluation tool of the development level and economic potential of the country are investigated. It is determined that it is the most complex and accurate indicator, that characterize the level of manufacturability and diversification of a particular national economy. It is found out that the index can be considered not only as a descriptive indicator, but also as a tool for predicting the growth of the country's economy. The ability of the index to predict changes in gross national income per capita more accurately than traditional management tools, such as the human development index or the global competitiveness index, is estimated. The nature and stability level of the correlation between the level of gross national income per capita and the value of economic complexity index are characterized. It has been found that the index also provides a statistically more accurate explanation of interstate variations in income inequality than the Kuznets curve. In particular, a negative correlation with the Gini coefficient was analyzed, which allowed to suggest that the distribution of income in complex economies is more uniform than in simple ones. Practical importance. The relationship between the effectiveness of the education system in the country and its economic complexity is considered. It has been established that one of the most important priorities for any country is the creation of high-quality and available education as a process of transferring accumulated knowledge and skills. It is determined that the main factors of a successful economy are a developed manufacturing sector, a network of technological knowledge between universities and enterprises, as well as a high quality of human capital
