Abstract
To evaluate the safety of stent malapposition of corrodible nitride iron stent as biodegradable cardiovascular implants, a total of 108 stents were implanted into the abdominal aortas, iliac arteries, and iliac artery bifurcations of 36 New Zealand white rabbits separately. Each rabbit was implanted with three stents. After a follow-up period of 3 months, no thrombus and embolism were found in local and downstream vessels. And no other adverse events occurred either. Stent strut covered by endothelial layer started to show signs of degradation, while struts exposed to bifurcated blood flow covered by a layer of tissue and no rust particle was found on the surface. Also, there were no traces of thrombosis and traces of excess inflammation. The authors conclude that the risk brought by stent malapposition in less than 9 months is acceptable.

Published: August 2021

Introducción: Las enfermedades degenerativas de la cadera y la columna vertebral son causas comunes de discapacidad y dolor y los síntomas suelen superponerse. Cuando algún parámetro se altera, otro debe modificarse para evitar el choque femoroacetabular y una posible luxación. Se piensa que la fijación lumbar afectaría la adaptación de la unidad espino-pélvica en las diferentes posturas. El objetivo de este estudio fue analizar el comportamiento espino-pélvico en pacientes con artroplastia total de cadera y artrodesis lumbar.
Materiales y Métodos: Se realizó un estudio no aleatorizado, retrospectivo, de casos y controles en pacientes con artroplastia total de cadera evaluados con radiografía lumbopélvica de frente y de perfil en posición erecta y en sedestación, divididos en dos grupos: con artrodesis lumbar o sin ella. Se midieron parámetros espino-pélvicos y femoroacetabulares.
Resultados: La muestra tenía 50 pacientes: 25 en cada grupo. Quince tenían artroplastia total de cadera bilateral y el nivel de fijación lumbar más frecuente era L5-S1. No hubo diferencia estadísticamente significativa en la edad y el sexo entre ambos grupos. Los pacientes con artrodesis lumbar necesitaron más flexión de cadera para sentarse, sin un aumento significativo asociado en la tasa de luxación.
Conclusiones: La composición ideal de los componentes aún es difícil de alcanzar. La reconsideración de las “zonas seguras” de los componentes ha comenzado a alejarse de los valores del plano coronal de Lewinnek. Se ha propuesto un nuevo enfoque en las zonas seguras del plano sagital más apropiadas y precisas en pacientes seleccionados con enfermedad espino-pélvica grave.

Published: August 2021

The purpose of this article is to develop and improve systemic methods for constructing solutions to engineering problems. The article provides a methodological approach to solving complex engineering problems based on the application of the system analysis method. The need for a preliminary assessment of the completeness of the initial data for the construction of a mathematical model of the problem is shown.
At the stage of the problem statement, the problem statement is concretized in order to establish the research goal. As a result of a systematic analysis of the functional characteristics of the object under study, the main parameters and their relationship are determined, and the values of these parameters characterizing the initial state of the object under study are established. It is necessary to clarify the essence of the problem and formulate it so that the solution found is effective and can be obtained using existing means and in real terms. Based on the data of the analysis, the goal of solving the engineering problem is determined and the corresponding formulation is formulated in the following form: initial data; parameters; quantities to be determined.
The functional connections between the main parameters of the object and the factors acting on it are established, they are described by mathematical relations and equations included in the mathematical model, taking into account the determining influence of the parameters of the problem on the state of the object. Thus, we obtain a mathematical formulation of the problem, the construction of the solution of which allows us to establish the parametric dependence of the state of the object for various values of the parameters. The reliability of the results obtained and the suitability of the chosen method, the decision should be confirmed by their testing and careful analysis.
On the basis of the formulated approach, assessments have been carried out and the corresponding technological operations have been proposed for solving the engineering problem of removing the tanker «Delfi» from the aground in the water area of the Odessa coast of the Black Sea. The expediency of further improvement of the technology of application of the proposed approach for design tasks and industrial development of software and hardware complexes has been determined.

The Structure of Personnel Training within Getting Higher Education Meets the Needs of Economy: Problems and Solutions
Authors: Blinova T. N. , Fedotov A. V. , Kovalenko A. A. 
Published: August 2021

This research article studies the problem of inconsistency of higher-educated personnel training structure to the current and future sectoral specialization of the Russian economy. One of the key tasks of the higher education system in any country is to train personnel who would be demanded by economy in the future. The responsibility for balancing the structure of training higher-educated personnel with the needs of organizations and various industries lies both on the government authorities and on the universities themselves. The authors analyze the correspondence of the structure of training personnel with higher education to the current and future needs of the socio-economic development of Russia in general and its regions in particular. In the course of the study, the structure of training personnel with higher education by enlarged groups of specialties and training programs has been compared with the current and prospective structure of the gross regional product, as well as with the distribution of the employed by sectors of the economy of all Russian Federation constituent entities. The results of the analysis by federal districts are based on the data obtained for the constituent entities, and make it possible to assess the imbalance in the structure of training personnel with higher education, to formulate possible reasons for the existing imbalances at the regional, federal, and universities’ levels. The study is based on the documents of the Ministry of Education and Science of Russia concerning the distribution of admission control figures by the Russian Federation entities and enlarged groups of specialties and training programs, aswell as on the information from the Federal State Statistics Service. For most regions of Russia, the results of the analysis revealed the problem of inconsistency between higher-educated personnel training structure and the structure of the need for personnel as determined by the goals and objectives of socio-economic development. A possible way to solve this problem is to revise the universities’ development programs with due consideration of the long-term regional development prospects supported by a system of institutional measures on the part of education authorities, industries, and regions.

Published: August 2021

In the context of the COVID pandemic, there has dramatically increased the significance of distance learning technologies. Higher education will most probably increase their usage even after overcoming the coronavirus. This paper aims at assessing Russian university students’ readiness to exercise distance learning technologies. The survey within Rostov-on-Don universities provided data on 428 students’ skills in using Internet technologies when studying. It is shown that in the pre-pandemic period, no more than a quarter of students had the necessary skills to participate in video conferences, and about 16 % of students took online courses autonomously. Only 6,5 % of the respondents could manage both technologies that comprise distance learning. The results obtained on the relationship between academic performance and self-participation in online courses, as well as on the relationship of these indicators with general digital literacy and immersion in social networks, should be taken into account within wide computerization of education during the pandemic.
Russian Flagship Universities’ Incomes: Dynamics and Tendencies
Authors: Korchagina I. V. 
Published: August 2021

This research article aims at identifying the impact of establishing flagship universities on the dynamics and structure of their income. The study is based on analyzing the growth rate of total income and income per 1 scientific and pedagogical worker in 2019–2020 as compared to 2015 reference year (taking inflation into account), together with finding out changes in the share of off-budget revenues, revenues from research and development work. There are used standard techniques of descriptive statistics, paired Student’st-test for related samples, Mann-WhitneyU-test, and cluster analysis. The total income of all flagship universities has grown, but, however, show deeper differentiation. The group of leaders have increased their revenues by 0,5–1,0 billion rubles in 2015 prices, but a number of universities face stagnated or declining income. The COVID-19 pandemic has had little or no impact on income differentiation and dyna mics. The by-income stratification per 1 scientific and pedagogical worker is lower, which indicates a personnel decrease in a number of clusters with stable or declining income. Neither institution’s joining the first or the second wave of flagship universities nor the availability of special federal funding has a statistically significant relationship with income dynamics. At the same time, the majority of flagship universities get the same stable share of income from research activities and did not decrease their dependence on the budget system. This indicates either the absence of major chan gesor the simultaneous growth of income from research activities and additional funding like federal programs, projects, grants. Not all flagship universities have been able to increase revenues, so the leaders’ experience requires further analysis. The results of the study may possibly be of interest for managers of both flagship and other categories of universities, as well as for those who are going to substantiate management decisions within the latest Priority-2030 program.

Authors: Buitrago Bermúdez Oscar 
Published: August 2021

En primera instancia se presenta la distribución espacial de los precios comerciales de la tierra rural en los municipios contiguos a Bogotá para el año 2000, como análisis previo a la determinación de los factores formadores del precio. Enseguida se presentan los resultados de los análisis multivariados realizados con un conjunto de variables que muy probablemente determinan el precio de la tierra en zonas rurales de influencia directa metropolitana, a partir de los cuales se determina la correlación entre ellas y con el precio catastral de los predios, dichos análisis se hicieron a partir de dos técnicas multivariadas: componentes principales y regresión lineal múltiple. Se llega a concluir que la distribución espacial de los precios de la tierra en los municipios contiguos a Bogotá está definida predominante por la red vial y un patrón de uso del suelo, y que los factores que determinan los precios de la tierra en la zona de estudio son la entidad territorial político-administrativa (es decir el municipio), el tipo de propietario y la accesibilidad, en contraposición a variables como el potencial agrícola, la presencia de aguas o el relieve.

Published: August 2021

Background:The subtalar joint has a complex anatomic function that includes inversion and eversion of the hindfoot, assisting in walking on uneven surfaces. Arthritis is the most common pathological condition affecting this joint and can require fusion. The surgery can be performed open or with arthroscopic assistance. This systematic review assesses articles written on the safety and efficacy of isolated arthroscopic subtalar fusion.Methods:Using MEDLINE and Embase, we systematically reviewed articles published before May 21, 2020.Results:Of 395 articles, 17 on a total of 395 patients (409 operations) were included in the review. The average duration of follow-up was 40.0 months (range, 3 to 105 months). Radiographic evidence of union was reported for 95.8% of cases at an average of 11.9 weeks (range, 6 to 56 weeks) postoperatively. Delayed union was reported in 1.0% of patients and nonunion, in 4.3% of patients. In the articles reporting patient satisfaction, including pain relief, 95.4% of patients had positive outcomes. Postoperative complications were reported in 64 patients (16.2%), including 37 (9.4%) with symptomatic implants, 11 (2.8%) with dysesthesia or neuropathic pain, and 3 (0.8%) with postoperative infection.Conclusions:Arthroscopic subtalar fusion is a safe and effective alternative to open subtalar arthrodesis, with high patient satisfaction rates, high union rates at similar follow-up intervals, and low complication rates. The aim of future research should be to determine the ideal cases for this approach as well as the most efficient arthroscopic surgical technique and postoperative rehabilitation to optimize function and union as seen on radiographs.Level of Evidence:TherapeuticLevel IV.
