Метод пружних розв’язків у задачах радіаційної повзучості, в яких враховуються вплив напружень і накопиченої незворотної деформації на радіаційне розпухання матеріалу
Authors: Чирков О. Ю.
Published: December 2021

Розглядається метод пружних розв’язків для розв’язання нелінійних крайових радіаційної повзучості, які дають змогу описувати неізотермічні процеси непружного деформування з урахуванням радіаційного розпухання і радіаційної повзучості опроміненого матеріалу. Для моделювання процесів радіаційного розпухання і радіаційної повзучості застосовуються сучасні підходи, в яких враховується пошкоджуюча доза, температура опромінення, вплив напруженого стану і накопиченої незворотної деформації. Досліджується модифікований метод пружних розв’язків для розв’язання крайових задач радіаційної повзучості. Враховується, що побудова та дослідження властивостей ітераційного методу в задачах радіаційної повзучості ускладнюється тією обставиною, що для доведення збіжності та оцінки точності послідовних наближень необхідно враховувати досить жорстке обмеження, зумовлене з несиметричністю оператора, який пов’язує похибки ітераційного процесу для двох послідовних наближень. За таких умов традиційний підхід дослідження збіжності ітераційного процесу з урахуванням властивостей самоспряжених операторів виявляється неприйнятним. Окрім того, стандартна процедура симетризації рівняння для послідовних наближень призводить до надмірно консервативних оцінок збіжності ітераційного методу, і тому оптимізація його швидкості збіжності має досить наближений характер. Цю задачу розв’язано завдяки використанню спеціальної норми для аналізу збіжності послідовних наближень, що дозволило побудувати модифікований ітераційний процес та довести його локальну збіжність для загального випадку рівнянь радіаційної повзучості. Докладно вивчено властивості модифікованого процесу і на цій основі одержано апріорні оцінки асимптотичної швидкості збіжності послідовних наближень та сформульовано підходи щодо оптимізації методу пружних розв’язків стосовно задач радіаційної повзучості.

Elevated levels of low-density lipoprotein (LDL-X) cholesterol, apolipoprotein B (ApoB), and especially oxidized LDL in plasma are associated with an increased risk of cardiovascular disease (CVD). The aim of the study was to determine the levels of ApoB and oxLDL in the blood of patients with diabetes mellitus (DM), CVD and COVID-19. ApoB and oxLDL were determined using enzyme-linked immunosorbent assay kits (Elabscience, USA). The measurements were performed at an optical wavelength of 450 nm. It was found that ApoB and oxLDL levels in the blood of patients with diabetes and, especially, with COVID-19 are substantially higher than in the blood of healthy people. Blood levels of ApoB and oxLDL are higher in patients with both COVID-19 and diabetes or CVD as com pared to patients with COVID-19 without comorbidities. Thus, the levels of ApoB and oxidized LDL may be the promising markers of severe COVID-19.
ISSUES OF COMPETITION OF THE RULES OF THE CODE OF UKRAINE ON BANKRUPTCY PROCEDURES AND THE LAW OF UKRAINE “ON EXECUTIVE PROCEEDINGS” IN CASES OF INSOLVENCY OF INDIVIDUALS

Published: December 2021

The Code of Ukraine on Bankruptcy Procedures is the first insolvency law codified in domestic legislation. The legislative novelty is the so-called consumer bankruptcy provided by the Code, the restoration of solvency through the settlement of problem debts of individuals, individuals – entrepreneurs to banks, microfinance organizations, arrears of taxes, fees and other mandatory payments within the framework of litigation, and in case of impossibility – their repayment (write-off) in the procedure of debt repayment. In addition, the new Code offers special conditions for addressing the issue of “foreign currency borrowers”, which has become relevant for many Ukrainians after the financial crisis of 2008. In general, the procedure for restoring the solvency of individuals is designed to encourage responsible borrowing, start or resume business, increase economic activity and taxable income, aimed at preventing crime and unemployment. Such a procedure is beneficial not only to the debtor, but also to the state. An individual, getting rid of debts, returns to active legal work, and the state returns another economic unit to an active lifestyle, acquires another taxpayer. In addition, the procedure provides creditors of the debtor – an individual with legal grounds for instalment and (or) write-off of part of the debt, as well as improving their own financial performance. However, currently many norms of the Code and other acts of the legislation of Ukraine are inconsistent, which causes conflicts during their practical application. The article considers some aspects that arise in cases of insolvency of individuals, individuals – entrepreneurs during the competition of the Code of Ukraine on Bankruptcy Procedures and the Law of Ukraine “On Enforcement Proceedings”, which relate to: suspension of enforcement proceedings during the moratorium on satisfaction of claims creditors; removal of arrests (encumbrances) in the procedure of debt repayment; consequences of the completion of the debt repayment procedure (including the exclusion of a person from the Unified Register of Debtors), identified problematic issues and proposals for their improvement by making appropriate changes to the legislation of Ukraine.
LEGAL ISSUES OF IMPLEMENTING THE INSTITUTE OF AUTHORIZED ECONOMIC OPERATOR
Authors:   Vasyl’ Stus Donetsk National University, Vinnytsia, Ukraine, Derkach Е.М.
Published: December 2021

The article covers current legal issues on implementing the institution of an authorized economic operator (AEO). The directions for developing the domestic economic and transport legislation are outlined. According to the International Monetary Fund data, supply chain disruptions have become a major challenge for the global economy since the start of the pandemic caused by COVID–19. Shutdowns of factories in China in early 2020, lockdowns in several countries across the world, labour shortages, as well as demand for tradable goods, disruptions to logistics networks have resulted in big increases in freight costs and delivery times. It is noted that the ongoing problems in the supply chain have caused some changes in the development of trade relations of Ukraine with other countries due to its transit state status. The institute of authorized economic operator was established in Ukraine according to the Law of Ukraine «On the amendments to the Customs Code of Ukraine on certain issues of functioning of authorized economic operators» adopted in October 2, 2019. It is emphasized that implementing the institution of the authorized economic operator corresponds to Ukraine’s obligations under the Association Agreement between the European Union and its Member States, of the one part, and Ukraine, of the other part. It is noted that more than 80 % of all customs clearance in the EU is carried out by companies with AEO authorization. A resident business entity as a participant of the international supply chain (including manufacturer, exporter, importer, customs representative, carrier, freight forwarder, warehouse keeper) may be authorized economic operators due to multi-stage conformity assessment system. In addition, the current legislation should be updated, in particular relevant provisions of the Economic Code of Ukraine, transport codes and laws in order to provide legal basis for authorized economic operators’ activities as the participants of freight transportation, as well as unifying the legal requirements for the AEO and carriers, freight forwarders, etc.
COURT’S DEFENSE OF PERSON’S RIGHTS IN A SPHERE OF CITY PLANNING BY PUBLIC ASSOCIATIONS: DEFINITION OF A PROBLEM
Authors:   Chernihiv Polytechnic National University, Chernihiv, Ukraine, Apanasenko K.I.
Published: December 2021

Unauthorized buildings are enough common problem of city planning in Ukraine. There is very popular practice to receive permissive documents after the beginning of building works and before commissioning. Therefore, effectiveness of activity of the Ukrainian State Architectural Building Service is not high. As a result, last decade some citizens and public organizations take part in struggle with city planning violations. Therefore, an investigation of a normative base of an appropriate activity of public organizations and court’s practice in this sphere is an actual task in purpose of an adoption of some legislative decisions. The author had identified position of Supreme Court on duty to application a rule about legal interest of a plaintiff. Only fact of an unauthorized building is not enough for its stopping on claims of not interested persons. The cessation of a town planning violation is possible only in condition of risk for rights and legal interests of plaintiffs (citizens and / or legal entities) or on actions of authorized state organs. The number of decisions of Supreme Court decided in favor of plaintiffs in cases on the claims of citizens and public organizations regarding unauthorized buildings of apartment buildings and other capital objects of town planning is small enough. Actual procedural legislation and normative legal acts which define a status of public organizations don’t provide its right to take legal action for a defense of rights and interests of legal entities and persons, territorial communities, public interests. Nowadays the question of provision public organizations by procedural interest in appropriate categories of disputes in the legislation kept up. Procedural interest of public organizations, its legal interest directly links to the question of court’s defense of public interests, with an institute of actio popularis. Because such organizations have to defend only public, not personal interest in accordance to its statutory object. It is important to understand that an interest for the stopping of illegal building cannot be personalize as an interest of any citizen. Therefore, it is an actual task to develop theoretical ideas about court’s defense of public interest. Nowadays Ukraine accepted the possibility of the defense of public interests only in spheres of consumer’s rights and ecological disputes. The legal public interest in other spheres of public life is not legitimize for the court’s defense. The author has made a conclusion about potential possibility and necessity of legislative recognizing of the right of public organizations to take legal action for the defense of rights of its members in the sphere of unauthorized buildings.

The article emphasizes that increasing of efficiency and competitiveness of Ukrainian industry can be achieved only by its transition to an innovative development way. The aim of the article is to analyze the indicators of innovation activity, invention and to develop proposals for the implementation of a number of measures in the context of the implementation of state regional policy to stimulate innovative development of industry. The article analyzes the indicators of innovation activity of Ukrainian industry in 2014-2019. The analysis of indicators of innovation activity of industrial enterprises, conducted in terms of technological levels of industrial development, shows the lack of stable trends in the dynamics of innovation activity. The general trend for all levels of produce-ability during the analyzed period is a decrease in the volume of sold innovative products. In general, the analysis of the main indicators of innovative activity of industry shows a decrease in the role of high-tech industries in the production and implementation of innovations. The existing potential of the regions in terms of inventions and utility models is analyzed. The analysis of the distribution of applications for inventions and utility models from national and foreign applicants-legal entities by type of industrial activity shows a decrease in inventive activity of enterprises in most types of industrial activity. The priority technical directions of patenting of inventions and utility models in the regions with the highest inventive activity are presented. It is emphasized that the low level of technological development of industry causes insignificant volumes of exports of high-tech products. The analysis shows a critically low level of high-tech exports in the regions of Ukraine, and somewhere its absence at all. It is claimed that the implementation of state regional policy in the regions of Ukraine is associated with the application of an integrated approach to the development and implementation of regional strategies. The use of an integrated approach will contribute to: improving the efficiency of the use of public funds aimed at the implementation of regional and local development projects, national, regional and sectorial programs, as well as programs for the development of problematic regions and the modernization of industry and infrastructure development in general. Under these conditions, the priorities of smart specialization of the regions are competitive advantages and guidelines for structural modernization of their economy.
LIMITATIONS AND OPPORTUNITIES OF SCIENTIFIC EDUCATIONAL AND INNOVATIVE SPHERES OF UKRAINE IN THE CONTEXT OF THE FORMATION OF REGIONAL SMART SPECIALIZATIONS
Authors:   Institute of Industrial Economics of NAS of Ukraine, Kyiv, Ukraine, Shvets N.V.
Published: December 2021

European methodology Strategy for Smart Specialization is being implemented in Ukraine. The success of this process is largely predetermined by the readiness and ability of regional scientific and innovation systems to effectively interact within the country and abroad. The characteristics of these systems are determined by the general state of the national spheres of scientific educational and innovative activities. Therefore, the purpose of the study was to comprehensively assess the actual situation in the scientific educational and innovation spheres of Ukraine and identification of constraints and opportunities for establishing scientific technological and innovative cooperation with EU regions in the context of smart specialization of regional economies. To achieve this goal, the SWOT analysis method, which is a classic strategic management tool, was applied. Literature review of the application of this method and the specificity of the research object showed the need to clarify the methodology for performing the SWOT analysis. Three stages of this analysis have been proposed. At the first stage, the formation of groups of factors of the external and internal environment of the research object and selection to the list of the most significant of them was carried out. The second stage included an assessment of the selected factors using the experts' intuitive-logical analysis. A feature of the applied approach is that the experts determined a quantitative assessment for the factors of the internal environment and a qualitative one for external ones. The third stage involved the establishment of strategically important logical relationships between internal (Strengths and Weaknesses) and external (Opportunities and Threats) factors, which were discovered at the first stage of the SWOT analysis. Because of performing three stages of analysis using an expert survey, limitations and opportunities that affect the prospects for Ukraine's integration into the European Research Area were identified. It was concluded that it is necessary to design a comprehensive state policy for the development of the knowledge and innovation sphere, which will also contribute to the achievement of the goals of regional smart specialization.

Based on literature analysis and own bioinformatics and virology research experience, authors propose multistep data processing algorithms, designed for the objectives of assisting the SARS-CoV-2 epitope vaccine production. Epitope vaccines are expected to provoke a weaker but safer response of the vaccinated person. Methodologies of reverse bioengineering, vaccinology and synthetic peptide manufacturing have a promising future to combat COVID-19 brutal disease. The significant mutational variability and evolution of the SARS-CoV-2, which is more typical for natural animal-borne viruses, are the hurdle for the effective and robust vaccine application and therefore require multidisciplinary research and prevention measures on the international level of cooperation. However, we can expect that other viruses with different nature and content may be labelled as SARS-CoV-2. In this case metagenomics is an important discipline for COVID-19 discovery. High quality reliable virus detection is still an unresolved question for improvement and optimization. It is of upmost importance to develop the in silico and in vitro methods for the vaccine recipient reaction prediction and monitoring as techniques of the so-called modern personalized medicine. Many questions can`t be solved applying exclusively in silico techniques and only can be discovered in vitro and in vivo, demanding significant time and money investments. Future experiments also should be directed at the discovery of optimal vaccine adjuvants, vectors and epitope ensembles, as well as the personal characteristics of citizens of a certain region. This research would require several more years of meticulous large-scale laboratory and clinical work in various centers of biomedical institutions worldwide

Program that searches for five types of fruits in the images of fruit trees, classifies them and counts their quantity is presented. Its creation took into account the requirement to be able to work both in the background and in real time and to identify the desired objects at a sufficiently high speed. The program should also be able to learn from available computers (including laptops) and within a reasonable time. In carrying out this task, the possibilities of several existing approaches to the recognition and identification of visual objects based on the use of convolutional neural networks were analyzed. Among the considered network archi-tectures were R-CNN, Fast R-CNN, Faster R-CNN, SSD, YOLO and some modifications based on them. Based on the analysis of the peculiarities of their work, the YOLO architecture was used to perform the task, which allows the analy-sis of visual objects in real time with high speed and reliability. The software product was implemented by modifying the YOLOv3 architecture implemented in TensorFlow 2.1. Object recognition in this architecture is performed using a trained Darknet-53 network, the parameters of which are freely available. The modification of the network was to replace its original classification layer. The training of the network modified in this way was carried out on the basis of Transfer learning technology using the Agrilfruit Dataset. There was also a study of the peculiarities of the learning process of the network under the use of different types of gradient descent (stochastic and with the value of the batch 4 and 8), as a result of which the optimal version of the trained network weights was selected for further use. Tests of the modified and trained network have shown that the system based on it with high reliability distin-guishes objects of the corresponding classes of different sizes in the image (even with their significant masking) and counts their number. The ability of the program to distinguish and count the number of individual fruits in the analyzed image can be used to visually assess the yield of fruit trees
Numerical algorithms for solving an elliptic optimal control problem with a power-law nonlinearity

Published: December 2021

The paper is devoted to the development and analysis of approximation-iteration algorithms based on the method of grids and the method of lines for solving an elliptic optimal control problem with a power-law nonlinearity. For the numerical solution of the main boundary value problem and the adjoint one, the second order of accuracy difference schemes are applied using the implicit method of simple iteration. Computational schemes of the method of lines for solving the above-mentioned elliptic boundary value problems are implemented in combination with the shooting method for the approximate solution of boundary value problems for the corresponding ordinary differential equations systems arising in the considered domain after lattice approximation. To minimize the objective functional, well-known gradient-type methods (gradient projection and conditional gradient methods) of constrained optimization are used. The essence of the proposed approximation-iteration approach consists in replacing the original extremal problem with a sequence of grid problems that approximate it on a set of refining grids, and applying an iterative gradient-type method to each of the "approximate" extremal problems. In this case, we propose to construct only a few approximations to the solution for each of the "approximate" problems and to take the last of these approximations, using piecewise linear interpolation, as the initial approximation in the iterative process for the next "approximate" problem. The sequence of the corresponding piecewise linear interpolants is considered as a sequence of approximations to the solution of the original extremal problem. The paper discusses the theoretical foundations of this combined approach, as well as its advantages over traditional methods using the example of solving a model optimal control problem

Modern control and diagnostic systems (CDS) usually determine only the technical condition (TC) at the current time, ie the CDS answers the question: a complex technical system (CTS) should be considered operational or not, and may provide little information on performance CTS even in the near future. Therefore, the existing scenarios of CDS operation do not provide for the assessment of the possibility of gradual failures, ie there is no forecasting of the technical condition. The processes of parameter degradation and degradation prediction are stochastic processes, the “behavior” of which is influenced by a combination of external and internal factors, so the deg-radation process can be described as a function that depends on changes in the internal parameters of CTS. The hybrid method involves the following steps. The first is to determine the set of initial characteristics that characterize the CTS vehicle. The second is the establishment of precautionary tolerances of degradation values of the characteristics that characterize the pre-failure technical con-dition of the CTS. The third is to determine the rational composition of informative indicators, which maximally determine the "behavior" of the initial characteristics. The fourth — implementa-tion of multiparameter monitoring, fixation of values of the controlled characteristics, formation of an information array of values of characteristics. Fifth — the adoption of a general model of the process of changing the characteristics of the CTS. Sixth — the formation of a real model of the process of changing the characteristics of Y(t) on the basis of an information array of values of char-acteristics obtained by multi-parameter monitoring. Seventh — forecasting the time of possible oc-currence of the pre-failure state of the CTS, which is carried out by extrapolating the obtained real model of the process of changing the characteristics of Y(t). It is proposed to use two types of mod-els: for medium- and long-term forecasting - polynomial models, for short-term forecasting — a lin-ear extrapolation model. At the final stage, forecast errors are determined for all types of models of degradation of pa-rameters and characteristics. Based on the results of the forecast verification, the models are adjust-ed

Підприємці та підприємництво у гірничій промисловості Донецького басейну в пореформений період (1860-1890-ті рр.)
Authors: Шляхов О. Б.
Published: December 2021

Мета дослідження – висвітлити особливості розгортання підприємницької діяльності в кам’яновугільній промисловості Донбасу протягом другої половини ХІХ ст. Використано методи дослідження: історико-генетичний, ретроспективний, діахронний. Наукова новизна: на основі широкого кола джерел охарактеризовано підприємницькі практики представників ділового світу Російської імперії в гірничій галузі Донецького басейну пореформеного періоду. Основні результати. Зазначено, що в пореформений період у вугільній промисловості Донбасу виникали десятки приватних підприємств та компаній, наживалися великі статки. Головними рисами гірничопромисловців, і перш за все представників технічної інтелігенції та купецтва, були висока енергія, обачливість у справах та наполегливість у досягненні мети. Водночас нестача капіталів, а також спеціальних знань обумовили той факт, що чимало шахтовласників регіону (переважно місцевих поміщиків) у своїх бізнесових практиках зазнавали краху, а їх підприємства діяли відносно короткий час. Наголошено, що значну роль у розбудові кам’яновугільної промисловості Донецького басейну в 90-ті рр. ХІХ ст. відіграв іноземний капітал. Звернуто увагу, що за національною ознакою серед гірничопромисловців Донбасу домінували росіяни. Разом з тим до видобутку вугілля в регіоні активно долучалися етнічні українці. При цьому більшість підприємців українського походження, які займалися бізнесом у гірничій галузі, за розмірами їх прибутків можна віднести до середньої (щорічний зиск від 2 до 10 тис. крб.) або дрібної (переважно селяни) буржуазії. Тип статті: описова.

Розглянуто сторінки життя видатного українського вченого, який зробив великий внесок в формування теоретичної бази зі збагачення природних та штучних водойм кормовими ресурсами в умовах Степової зони України. Петро Олексійович Журавель – доктор біологічних наук, професор, зробив не тільки великий внесок у розвиток дніпропетровської гідробіологічної школи, а був дуже чуйною та добропорядною людиною. Його учні та послідовники з великим теплом згадують про нього і підкреслюють як легко було спілкуватися з Петром Олексійовичем, він завжди був небайдужим до чужих проблем, володів дуже цікавим та яскравим почуттям гумору. Протягом 50-х років під керівництвом професора П. О. Журавля ці дослідження були розгорнуті у широку багаторічну програму робіт з вивчення біології, екології та поширення представників лимано-каспійської фауни. Особлива заслуга професора П. О. Журавля полягає в інтродукції й акліматизації кормових безхребетних і риб у водосховища півдня України та Криму; акліматизації в Чорноріченське (Севастопольське) водосховище Криму біофільтраторів, риб та кормових для них організмів з лиманої фауни для підвищення кормової бази риб та поліпшення якості води.
Productividad en Colombia: un desafío pendiente
Authors: Sanchez Perez German , Sánchez-Ruiz Hernando
Published: December 2021

En este artículo se examina el comportamiento de la productividad laboral en Colombia, en el periodo 1975-2016, desde dos perspectivas o enfoques metodológicos: el espacio referencial y la desagregación temporal y sectorial. Desde la primera perspectiva, se concluye que el crecimiento de la inversión por empleado superó —con excepción de dos años— el aporte de la productividad; es decir, no se presentaron eventos innovadores que reflejen la concepción schumpeteriana, que abarquen toda la economía de manera persistente. Con la segunda perspectiva metodológica se aporta evidencia que confirma las grandes diferencias de productividades entre sectores en el país, el fenómeno de la heterogeneidad, y se concluye que aquellos sectores que ostentan las mayores eficiencias son los que emplean menos trabajadores.
Turismo sostenible: un modelo de crecimiento con recursos naturales
Authors: London Silvia , Rojas Mara Leticia , Candias Karen
Published: December 2021

En el marco de la Agenda 2030 del PNUD y los Objetivos del Desarrollo Sostenible, las actividades intensivas en el uso de recursos naturales son de gran interés. Entre ellas se destaca el turismo como actividad impulsora del crecimiento. Sin embargo, dicha actividad también causa daños ambientales que podrían, incluso, minar la base de la propia industria turística. Así, este artículo presenta un modelo de crecimiento sencillo de generaciones solapadas y análisis discreto para economías basadas en turismo con uso intensivo en recursos naturales. Los resultados muestran que la posición final de la economía está determinada por el grado de utilización de los recursos en la actividad turística, la impaciencia de la población respecto de las decisiones de consumo intertemporal —preferencia intertemporal—, la presencia de polución y la existencia o ausencia de medidas de mitigación. Se concluye la presencia de un autorreforzamiento positivo entre los recursos económicos destinados al desarrollo de la actividad y el stock de recursos naturales, si las medidas de mitigación son las adecuadas. El aporte es hacia la formulación de política al reconocer los fundamentos de los mecanismos causales que conducen a un resultado de turismo sostenible.
