ROLE OF POLITICAL LEADERSHIP IN MIGRATION MANAGEMENT IN THE EUROPEAN UNION
Authors:   Astrakhan State University, VERONIKA V. SHKOLNAYA
Published: October 2021

This article examines the importance of political leadership in the modern conditions of widespread migration processes around the world. Particular attention is paid to the characteristic features of political leadership in the countries of the European Union. The above mentioned problem was rarely raised in the works of Russian and foreign researchers, and therefore it acquires special relevance and need for consideration. In addition, the importance of studying the role of political leadership in managing migration processes in the European Union is due to the fact that at present political leadership has largely remained beyond the vision of migration researchers. The paper describes in detail the existing concepts, reflecting the possibility of the impact of political leadership tools on the regulation of migration processes, and considers practical examples of the use of effective migration policy. At the same time, attention is also paid to local political leadership in some states of the European Union, which makes it possible to study the problem in more detail. As a result, possible ways of transforming the migration policy of the European Union countries on the part of political leaders are given, and practical measures and mechanisms for effective border management are considered.

Los quince capítulos de Desde otros Caribes: fronteras, poéticas e identidades ponen en escena a “otros Caribes” en un performance dialógico y transdisciplinario que permite su discusión como actores en un espacio Caribe diverso e interrelacionado. Plantean nuevos diálogos hacia dentro y fuera del área, en un acto consciente de construcción de poéticas dinámicas, transdisciplinarias y transfronterizas. Las discusiones abordadas tienen orígenes en planteamientos arraigados en la historia, la literatura, la geografía, el arte y la cartografía y transitan hacia espacios transdisciplinarios que exploran los nexos, y los diversos planos de conectividad que permiten profundizar en el área Caribe y su devenir. Lejos de ser una propuesta que amplía sin límites al área, el libro profundiza en las historias de arraigo que se comparten de manera performática en la región, las historias profundas de estos otros Caribes.
COVID-19 vírus második hullámában tapasztalható foglalkoztatási kihívások a vállalatok szemszögéből
Authors: Barbara Pirohov-Tóth
Published: October 2021

Absztrakt. A Covid-19 vírus hatására megváltozott piaci körülmények a vállalatokat stratégiájuk és struktúrájuk újragondolására, valamint folyamataik optimalizálására kötelezte. Kutatásom célja, hogy rávilágítsak azokra a koronavírus-járvány második hullámában bekövetkező változásokra, amelyek jelentős hatást gyakoroltak a vállalkozások működésére és jelentős kihívások elé állították őket. A vizsgálathoz egy korábbi kérdőíves vizsgálat (Pirohov-Tóth 2020; Pirohov-Tóth, Kiss 2021) eredményeit használtam fel, melyek szakirodalmi forráselemzéssel, valamint a Központi Statisztikai Hivatal adatbázisának statisztikai adataival kerültek kiegészítésre. Továbbá a vírus első hullámához viszonyítva megvizsgáltam, hogyan változott a munkahelyek termelékenysége a vírus második hullámában. Végezetül pedig olyan vállalati válságkezelési lehetőségek kerültek bemutatásra elemzésemben, melyek gyakorlati alkalmazása hozzájárulhat a válságból való újbóli felemelkedéshez. Megállapítható, hogy a digitalizáció felgyorsulása, valamint a fejlett technológiai eszközök és módszerek széleskörű kiterjesztése a vírus helyzet egyik legnagyobb pozitívumának tekinthető, mely a vállalatok számára e pandémiás helyzetben a túlélést is jelentheti.

Az üzemek berendezései műszaki állapotának romlása napjainkban általános jelenség. Mindez a hazai és nemzetközi hatósági tapasztalatok szerint egyre növekvő mértékben járul hozzá az üzemzavarok és balesetek bekövetkezéséhez. Azon üzemek, amelyek nem megfelelő állapot megőrzési stratégiával működtetnek napjainkban tervezési élettartamuk végéhez közelednek, így fokozott baleseti kockázatot jelentenek. Az öregedési folyamatokat gyakran gyorsítja a berendezéseket érő igénybevételek hatásainak és az állapotromlási mechanizmusok mértékének üzemeltető általi alulbecslése, illetve ennek következtében az állapot nyomonkövetési és karbantartási eljárások nem megfelelő kialakítása és működtetése. Munkánk célja a hazai és külföldi trendek vizsgálata a karbantartás modern optimalizálási módszerei tükrében és ehhez kapcsolódóan javaslattétel a karbantartási ütemezés optimalizálására vonatkozóan a hazai munkáltatók számára.

Published: October 2021

Additive manufacturing (AM) is a process in which the product is composed of overlapping layers of a material that is added using devices such as 3D printers. Its process has been evolving for decades and nowadays it can be used for several applications and with different materials. One modern usage is for medical and dental purposes. Since it became possible to print metal, it has been a good solution for bone implants, once it must be done with biomaterials and can now replicate the bone structure, for that unit cells should compose the implant. Both conditions are now possible to be achieved by AM, and the current study will analyze, using finite element method, the possibilities to create specimens for tests which the final product would result in a 3D printed bone implant.

Published: October 2021

Optimization relates to the ultimate yield strength and the maximum stress incident on the current model under critical working conditions and finds through iterative processing a way to compensate for the strength requirement without going beyond the desired mass limits. In this paper, the horizontal sheet metal base of a horizontal toggle clamp is optimised for mass reduction using the finite element analysis in the computer aided design software. The sheet metal base material is the ANSI32 Steel. In the design software, it is designed with the thickness of 7 mm and it is intended to support a workload of up to 750 N. The constraints were a fixed point added at all the holes and at the bottom surface of the sheet metal base. A number of iterations were made for the 750N loading force across the base plate to run the simulation. For optimization, the aim was to minimize the mass of the base plate. The design parameters  were Von Mises, factor of safety and displacement. The variables were the slots’ width and material thickness along the mid-surface of the sheet metal. The mass was reduced by more than thirty per cent overall.
Nursing students’ satisfaction with the academic program: A cross sectional study
Authors:   Department of Nursing Administration, Alexandria University, Alexandria, Egypt, et al. El Seesy
Published: October 2021

In higher education, students’ satisfaction is viewed as an indicator of program success, and higher satisfaction levels among students are correlated with better intellectual and social achievements. This study aimed to assess nursing students’ satisfaction with the academic program at one academic institution. A cross-sectional descriptive study was conducted. A convenience sampling method was used to include 328 students using the Undergraduates Nursing Students Academic Satisfaction Scale (UNSASS) to assess the level of nursing students’ satisfaction with the academic program. The overall mean score of satisfaction was 51.72 out of 100 (SD=14.63). The highest score was observed regarding the program design and delivery dimension (mean±SD score=53.91±18.51), while the lowest satisfaction score was attributed to the support and resources dimension (49.62±18.13). The study recommends conducting a comprehensive and consistent evaluation to measure student satisfaction and expectations in resources and facilities in order to guide decision-making and improve the effectiveness of students’ educational programs. It is suggested that the UNSASS may expand its applicability to master students and evaluate programs that are not accredited by international accreditation in future studies.

BACKGROUND

At the beginning of the COVID-19 pandemic, many low-income countries were confronted with a difficult challenge: with little resources and while implementing a stringent lockdown, they had to rapidly train thousands of Community Health Workers (CHW) in rural and remote areas about the new virus and then find a way to continue to support them in providing health services and products. Shortly after the first COVID-19 case was confirmed in Uganda, a local consortium developed a telehealth approach that aimed to inform 3500 CHWs about COVID-19, support them in identifying, referring and caring for possible COVID-19 cases and help them to continue to provide basic health services and products.

OBJECTIVE

To assess the functioning of the telehealth approach that was set up to support community health workers in rural communities in Uganda with sustaining basic health services and dealing with the COVID-19 pandemic.

METHODS

For this mixed-method study, we combined analysis of 1) consultation data from the call-center that supported a network of 3500 CHW in 23 districts in rural Uganda, 2) 24 in-depth interviews with purposively selected CHWs and health professionals working at the call center, and 3) two surveys of 150 active CHWs

RESULTS

Between March 2020 and June 2021, a total of 35,553 consultations took place via the call center. While the CHWs made extensive use of the call center, they rarely asked for support for potential Covid-19 cases. The CHWs said there were no signs that people in their communities were suffering from severe health problems due to COVID-19. Because COVID-19 appeared to cause no visible health problems, many people were skeptical about the danger of COVID-19. At the same time, people in rural areas were afraid to report relevant symptoms and get tested for fear of being quarantined and stigmatized.
The telehealth approach did prove useful in supporting CHWs in providing regular health services and products in rural communities. The health professionals at the call center supported CHWs in diagnosing, referring and treating patients, adhering to infection prevention and control practices, and communicating product needs. The CHWs felt more informed and less isolated and said the support helped them provide better care and improve the delivery of essential health products.

CONCLUSIONS

The telehealth approach, launched at the start of the COVID-19 pandemic, provided useful support to thousands of CHWs in rural communities in Uganda. The telehealth approach could be quickly set up and scaled up and offers a low cost strategy for providing useful and flexible support to CHWs in rural communities.

Published: October 2021

Background and objectives

Although progressive decline in physical activity and function are common in individuals with worsening CKD, little is known about the effect of dialysis initiation on physical activity. We assessed for any association of progression to dialysis in people with advanced CKD with temporal rates of change in physical activity and function.

Design, setting, participants, & measurements

Canadian Frailty Observation and Interventions Trial (CanFIT) participants with an eGFR of <30 ml/min per 1.73 m2 were included. Outcomes included change in physical activity level, measured using the Physical Activity Scale for the Elderly, and physical function, measured using the chair stand, 4-m gait speed, and grip strength tests. Generalized linear regression models were conducted to determine whether dialysis initiation was associated with greater decline in physical activity or function.

Results

Of 386 individuals, 162 progressed to dialysis. Both assessments were completed by 98% of individuals for the Physical Activity Scale for the Elderly, 86% for the chair stand test, 84% for the gait speed test, and 91% for the grip strength test. Median (interquartile range) interassessment follow-up was 427 (357–578) days for the “stable advanced CKD” group and 606 (428–1000) days for the “progressed to dialysis” group. Self-reported physical activity and gait speed significantly declined in both groups. Mean (SD) chair stand time increased from 20.8 (17.1) to 24.0 (21.0) seconds among patients with stable advanced CKD, and from 18.5 (15.4) to 27.4 (22.2) seconds among those who progressed to dialysis (adjusted difference in change, 5.2 seconds; 95% confidence interval, 0.8 to 9.7 seconds; P=0.02).

Conclusions

Patients with advanced CKD experience progressive declines in physical activity and function. Transition to dialysis is associated with accelerated decline in physical function, as measured by the chair stand test.
Study on Austrian actors, networks and activities in the field of science diplomacy. Bringing Austrian science diplomacy to the next step: Challenges, state of play and recommendations.
Authors:   ZSI - Centre for Social Innovation, Plumhans Laure-Anne , Dall Elke , Schuch Klaus
Published: October 2021

This study examines science diplomacy in Austria. ZSI was commissioned by the BMBWF between February and September 2021 to research how science diplomacy is currently understood and implemented and how the concept can be better anchored and promoted in Austria. Using literature and desktop research, an online survey, interviews and a focus group, this report answers the following key questions: how does the Austrian science diplomacy ecosystem looks like, who are its actors, what are the challenges and how could they be addressed? The complex task of presenting the current practical implementation of science diplomacy was carried out in this study in a survey that includes more than 150 actors and ranks them according to their importance in the system. Interviews with representatives of these organizations revealed that the term is well known. The actors note that they are already carrying out activities in the direction, and are also interested in intensifying this. However, there are concerns about using the term without a specific context. Accordingly, the concept is often not explicitly mentioned in institutional presentations and activities, and practices are often in other contexts. Furthermore, actors in the system are of course aware of each other, but there is no exchange on the topic of science diplomacy in particular. The corresponding (explicit) competencies and financial resources are lacking. This study also includes case studies that look at other countries' approaches: Perspectives from Japan, Finland, and Switzerland on science diplomacy are described. These and outstanding practices from other countries, as well as interviews and findings from a focus group with Austrian stakeholders, inspire five recommendations that conclude the report.

Published: October 2021

Introducción: Existen múltiples factores que pueden llegar a afectar la elección de una especialidad en médicos internos de pregrado. Estudios previos han demostrado que un gran porcentaje de los estudiantes de medicina no contemplan a la neurocirugía como una de sus opciones de especialidad a realizar en un futuro.Objetivo: Evaluar los factores que podrían generar interés o desinterés en realizar la especialidad en neurocirugía en médicos internos. De acuerdo con nuestra apreciación, este trabajo es el primero en el país que evalúa dicho aspecto.Método: Este estudio fue llevado a cabo mediante el uso de un cuestionario conformado por 15 preguntas basadas en escala Likert, aplicado a 50 médicos internos. El mismo ha sido utilizado en diversas publicaciones internacionales.Resultados: La mayoría de los estudiantes considera que la historia clínica neurológica es difícil de interrogar y los signos neurológicos son complicados de evocar. La mayoría de ellos (78%) no considera a la neurocirugía entre sus opciones de especialidad a realizar, por el largo periodo de formación que conlleva y porque puede afectar negativamente la vida familiar. Sin embargo, la mayoría de ellos (88%) reconoce que esta especialidad conlleva un alto prestigio e ingresos económicos.Conclusiones: Este trabajo concuerda con la caída en popularidad de la neurocirugía como especialidad reportada en publicaciones internacionales, y remarca algunas áreas objetivo que pueden ayudar a mejorar la percepción en los médicos internos.

Purpose. The aim of the work is to assess the role of the basic forces in formation of the dynamic structures of the upper layer in the Marmara Sea in different hydrological seasons. Methods and Results. The numerical model developed in Marine Hydrophysical Institute, Russian Academy of Sciences, was used to calculate the hydrodynamic and energy characteristics of the sea circulation. The horizontal spatial resolution was 1.22 × 0.83 km, 18 horizons were used vertically, and the time step was 0.5 min. The characteristics of the waters inflowing through the Bosporus and Dardanelles straits corresponded to the available observational data. On the sea surface, the daily average fields of tangential wind stress, heat fluxes, precipitation and evaporation for 2008 were preset; these parameters were calculated using the regional atmospheric model MM5. Spatial distributions of the vortex structures and the corresponding energy flows in the upper sea layer for different seasons were considered. Having been analyzed, the average seasonal spatial distributions of the current velocity fields and the components of the kinetic energy budget showed that during the year, the vortices in the upper sea layer were formed mainly by two mechanisms. In the central part of the sea, generation of a large-scale anticyclone and its seasonal variability are basically conditioned by the wind forcing, whereas formation and evolution of coastal cyclonic eddies are caused by the buoyancy force. In the fields where the buoyancy, pressure and friction forcing takes place, the zones of local extremes are distinguished. Two of them are the areas of water inflow through the Bosphorus and Dardanelles straits. The strongest variability is observed in the Bosporus region that is certainly conditioned by the fact that the inflowing Black Sea waters have a decisive influence on seasonal nature of the Marmara Sea circulation. The extreme values in the other zones are the result of the coastline structure heterogeneities, that leads to formation of the coastal eddies, the energy source for which is the available potential energy. Conclusions. Analysis of the results of the performed numerical experiment makes it possible to conclude that in the upper layer of the Marmara Sea, formation and variability of the central anticyclone are conditioned by the wind forcing, while those of the coastal cyclones – by the buoyancy effect

Purpose. The work is aimed at assessing the influence of choice of the parameterization scheme of the snow and ice radiation features upon reproduction of seasonal evolution of the snow-ice cover thickness and temperature distribution in it in the Taganrog Bay top part. Methods and Results. Thermal seasonal dynamics of the snow-ice cover thickness in the northeastern part of the Taganrog Bay was studied using a non-stationary thermodynamic model of sea ice. The model reproduces formation of ice and accumulation of snow on its surface, spatial-temporal change in their thermophysical characteristics, melting of the snow-ice cover, vertical distribution of temperature, and solar radiation absorbed in its thickness at a preset timed data on the meteorological parameters. In the numerical solution of the heat conductivity equation for snow and ice including a radiation source, a computational grid permitting to maintain spatial resolution of the temperature profiles in the snowice cover during its melting and growth was applied. Two variants of parameterization of solar radiation transfer in the sea ice were considered. The first version assumed exponential decay of radiation with the constant transmittance and attenuation coefficients. In the second one, a two-layer scheme of the solar radiation penetration into ice was used; it simulated the near-surface transition layer. Attenuation of intensity of solar radiation in the snow thickness was described by the Bouguer – Lambert law with the attenuation coefficient both as independent of the snow thermophysical characteristics and as represented by the function of its density. The numerical experiments with the purpose to reproduce seasonal evolution of the snow-ice cover thickness and its vertical temperature profile in the Taganrog Bay top part were performed for the winter season, 2016/17. Comparative analysis of the simulation results and the sea ice thickness values taken from the ESIMO ice maps made it possible to choose a combination of the model parameters that provides the best correspondence between the calculated and actual values. Conclusions. It is shown that in reproducing the seasonal changes in the ice cover thickness in the Taganrog Bay top part in winter, 2016/17, the choice of the transmittance and attenuation coefficients for white ice represented by the cloudiness functions, on the one hand, and the thickness of the layer with the most intense absorption of short-wave radiation ∼ 4 cm, on the other, turned out to be the most justified.

Purpose. Using the data obtained in the expeditions, 2001–2014, the authors intend to identify the typical features of vertical structure of the colored dissolved organic matter (fDOM) concentration field in the Kerch Strait, to type the fDOM(z) profiles, to zone the region under consideration according to a given set of the qualitative features, and also to determine the features of statistical characteristics of the fDOM concentration distribution on the sea surface layer for the water areas with a typical structure. Methods and Results. The typing was carried out by the method of visual expert assessment of the curves of vertical distribution of concentration of the considered value. It was based on analyzing the fDOM(z) profile shapes. To reveal the boundaries of the areas with typical stratification of the fDOM content field, the thermohaline field structure was analyzed. Three types of water vertical structure were identified; they differed in the fDOM(z) profile shape and in statistical indices of empirical distribution of this substance concentration on the sea surface. These are the Azov Sea and the Black Sea types peculiar to the Azov and Black seas waters not contaminated by dissolved organic matter, and the type, the structure of which identifies the waters containing the anthropogenic component in the concentration field of the analyzed value. The latter type is characterized by a special intrusive shape of the fDOM(z) profile. For each of the identified stratification types, the histograms of the fDOM concentration distribution on the sea surface were calculated. Conclusions. The fDOM(z) profiles were typed. The Kerch Strait water area was zoned in accordance with a given set of the preliminary revealed qualitative features. The boundaries of the areas with typical stratification and their displacements were determined. It is shown that each structure type has its own statistical distribution of concentration of the considered value on the sea surface.

Purpose. The purpose of the study is to analyze the features of vertical distribution of phosphates and dissolved organic phosphorus (Porg) in the Black Sea at the present period. Methods and Results. The data obtained by the scientists of Marine Hydrophysical Institute in the Black Sea within the economic zone of Russia in 2016–2019 were used. At more than 200 deep-sea stations, a cassette of 12 bathometers (the Seabird-Electronics STD-instrument) was applied for taking hydrochemical samples at certain isopycnic surfaces, usually at σt = 16.30; 16.25; 16.20; 16.20; 16.15; 16.10; 16.05; 16.00; 15.95; 15.90; 15.80; 15.50, 14.0 kg/m3. At the coastal shallow-water stations, samples were taken at the 10 m intervals. Such a scheme permitted to carry out vertical sampling in the upper mixed layer and in the suboxic zone (including its upper boundary) with possible minimum of phosphates, to determine the depth of hydrogen sulfide formation and the location of the phosphates concentration maximum in the upper part of the anaerobic zone. Conclusions. From the surface to isopycn σt = 14.4 kg/m3, the content of phosphates and Porg does not exceed 0.1 µM; below this isopycnic surface, the phosphates concentration begins to increase, whereas of Porg remains at the same level. At all the profiles of the phosphates vertical distribution, the phosphates concentration minimum was recorded near the isopycnic surface σt = 15.8 kg/m3, and its maximum – near the isopycnic surface σt = 16.2 kg/m3. The minimum content of phosphates varied within 0–1.5 µM; in 2016–2017 the phosphates concentration maximum did not exceed 8 µM; in 2018, in many cases, it was higher than 12 µM, and once, near the Kerch Strait, it exceeded 17 µM. Increase in the magnitude of the maximum phosphates concentration (in the previous studies in 1988– 2013, it did not exceed 8 µM) is assumed to be related to installation of the supports for constructing the Kerch Bridge.

Purpose. The work is aimed at updating the sea wave forecasting system developed in the Black Sea Marine Forecasting Center by including the block of wind wave forecast in the Sevastopol region and by improving the wave forecast accuracy using the proposed procedure for the SWAN model tuning. Methods and Results. In the updated forecasting system, the possibility of performing the joint operational sea wave forecasts for the Black Sea and the Sevastopol region (with the 5 and 1 km spatial resolutions, respectively) became possible due to the nested grid method applied. To improve accuracy of the wave forecasts, the procedure for the SWAN model tuning was proposed. It is based on changing the parameterization of the surface friction coefficient 𝐶𝑑(𝑉), where V is the surface wind speed. This permits to reduce the deviations of the forecasted wave heights from those obtained from the satellite altimetry measurements. Efficiency of the proposed procedure was assessed through comparison of the forecasting results with the remote sensing data. It is shown that in the forecasts supplied with an optimal choice of functional dependence 𝐶𝑑(𝑉), the scattering index between the forecasted and measured values can be reduced by 20 %. Conclusions. Represented is the updated system of the Black Sea Marine Forecasting Center intended for the joint operational sea wave forecasts in the Black Sea and in the Sevastopol region. The results of model validation have shown that the procedure proposed for tuning the SWAN model makes it possible to reduce the deviations of the forecasted wave heights from those measured by the sensors installed at the altimetry satellites.

Published: October 2021

Objective: To assess the association between gestational age at delivery
and postpartum severe acute maternal morbidity (SAMM) in twin
pregnancies. Design: Population-based, national, prospective, cohort
study Setting: From 02/2014 to 03/2015 in France Population: Women with
twin pregnancies who gave birth after 32 weeks of gestation. We excluded
women with fetal death or medical termination of either twin, with
antepartum SAMM, with antepartum conditions responsible for postpartum
SAMM. Methods: Gestational age at delivery was studied as the number of
completed weeks of gestation. We assessed the association between
gestational age at delivery and postpartum SAMM by using multivariable
multilevel modified Poisson regression modelling. Main Outcome Measures:
Composite criteria of postpartum severe acute maternal morbidity
Results: Among the 7,713 women included, 410 (5.3%) developed
postpartum SAMM, mainly (88.5%) postpartum haemorrhage. Compared with
the reference category of 37 weeks, the risk of postpartum SAMM was
significantly lower for all categories of earlier gestational age at
delivery (from aRR=0.34, 95% CI 0.17-0.68 at 32 weeks to aRR=0.71, 95%
CI 0.54-0.94 at 36 weeks), and did not differ for later categories.
Conclusion: In twin pregnancies, compared with delivery at 37 weeks,
delivery at earlier gestational ages is associated with a lower risk of
postpartum SAMM. Continuing pregnancy beyond 37 weeks is not associated
with an increased risk of postpartum SAMM. Funding: Supported by a grant

Published: October 2021

Despite the improvements in pharmacological and surgical treatments, cardiovascular diseases (CVDs) are the number one cause of death worldwide. During the last two decades, the search for new therapies has been revolutionized with the growing knowledge of stem cell biology. Due to their huge differentiation capacity and paracrine effects, mesenchymal stem cells (MSCs) are a promising tool for the treatment of CVDs. The encouraging outcomes of preclinical studies using MSCs as a treatment for diseased myocardium have set the scene for worldwide clinical trials. In this review, we overview either complete or ongoing clinical trials using MSCs for the therapy of CVDs. In particular, we analyze the biological properties of MSCs, elucidate recent clinical findings and clinical trial phases of investigation, highlight clinical therapeutic effects of MSCs, and discuss challenges towards the clinical use of these cells in the therapy of CVDs.

UNTYPICAL LOSSES UNDER PARAGRAPH 2 OF CLAUSE 5 OF ARTICLE 189.23 OF THE BANKRUPTCY LAW: A PARADOX OR HIDDEN MEANING?
Authors: EGOROV A.V.
Published: October 2021

At first sight, the aforementioned norm of the Bankruptcy Law hides a paradox: the Bank of Russia or another public entity provides a credit institution with financing on a gratuitous basis and therefore incurs losses (lost interest income), and the credit institution is vested with the right to recover these losses, i.e. a person who a priori did not experience such losses. This is contrary to any views on damages that exist in civil law theory. Therefore, in order to preserve at least some legal meaning behind the specified norm, it is necessary to understand what kind of economic regulation model its developers meant. Moreover, the judicial practice of applying this norm and recovering such “paradoxical” losses from controlling persons is beginning to take shape. That is, it cannot be said that the norm turned out to be stillborn and is blocked by the law enforcement officer. The best option is to believe that the Bank of Russia has a direct claim to the guilty persons to compensate for their lost profits, and the credit institution that has received financing from it is empowered to collect in its favor or the obligation to transfer it to it. The second important point of the norm under consideration is an attempt to shift the expenses of the Bank of Russia to the controlling persons for depositing funds into the bank’s capital. This happens in a veiled form – through interest on the amount recovered for 20 years in advance, which at the current refinancing rate means approximately 100% of the invested amount. However, it should be borne in mind that by investing such an amount, the Bank of Russia takes the bank’s business for itself, and then, transferring this business to other persons, it receives the proceeds. The owners of the bank do not receive any adequate compensation, but must reimburse the Bank of Russia up to 100% of their invested funds. This observation raises fundamental doubts about the constitutionality of this provision of the Bankruptcy Law.
Legal issues of implementation and protection of civil law in case of violation. Temporal aspect
Authors: Guyvan P.D.
Published: October 2021

This scientific article is devoted to the study of the topical issue of temporal dimensions of a person’s subjective right to protection of his violated civil rights. The paper argues that the existence of a legal relationship is an integral part of its content, outside the time of realization of the right to exercise it is impossible. In civil relations, the decisive factor is the dispositive factor for determining the duration of the obligation at the level of the creditor-debtor. But even with the uncertainty of the temporal coordinates of the relationship, the definition of «term of performance of an obligation» should be understood as a period of time during which the entitled person can exercise his right, as well as a period of time during which the obligor must perform his duty. Instead, the period during which the protection right is exercised, including the claim, as a rule, has a normative design. This shows the importance of the civil law term as an element of the content of subjective law: its expiration leads to certain legally significant consequences - the exhaustion of law. Otherwise, the significance of such a legal phenomenon as the term is simply leveled. Therefore, the author categorically denies the concept that the subjective rights and corresponding responsibilities of the parties to the binding relationship can be exercised outside the specified temporal coordinates. At the moment of the offense, a new independent binding relationship of a protective type arises, the content of which includes the protective claim of the right holder and the corresponding duty of the infringer. The subjects of these relationships of the already protective type will be the same persons as in the terminated regulatory relationship - the creditor endowed with the claim and the debtor burdened with the obligation. But the scope of rights, the nature of their exercise and, most importantly, the temporal characteristics will be different. In the case of judicial protection of the right, the statute of limitations will be decisive, in the case of out-of-court protective constructions, there are also their own time regulators. Therefore, the paper also assesses the question of the existence of a subjective right after the expiration of the statute of limitations - the term of existence of the substantive right to sue. It is concluded that the substantive right to protection (protection right) to fulfill the existing obligation does not end with the coincidence of the statute of limitations.
Evolution of ukrainian national security strategies during the years of independence through the prism of ensuring the economic security of the state
Authors: Shevchenko O.
Published: October 2021

The article reveals the evolution of Ukraine’s national security strategies during the years of independence. It is determined that at the state level a number of issues related to the creation of the most effective system of economic security of the state within the existing at different stages of statehood National Security Strategies of Ukraine, both at the legislative level and in the functioning of relevant competent state bodies. The content of ensuring the economic security of the state in the four strategies of national security of Ukraine is revealed. It is determined that the main goal of the National Security Strategy is to ensure a level of national security that would guarantee the progressive development of Ukraine, its competitiveness, ensuring human and civil rights and freedoms, further strengthening the international position and authority of our state in the modern world.Internal and external threats to national security in the field of economic security are studied. The state of implementation of national security strategies of Ukraine is analyzed and it is concluded that the purpose and goals of most of these strategies were not achieved due to: critical weakening of the main institutions of state power; growing protest mood in society; high level of corruption; some distortion of the basic mechanisms of public administration, which were to ensure the rule of law and strict compliance with the law; to some extent, low responsibility of the subjects of national security of Ukraine for the implementation of the tasks assigned to them; possible non-transparency of the main directions of expenditures on national security and defense; lack of effective control in the field of national security with the involvement of civil society institutions.It is stated that the new National Security Strategy of Ukraine 2020 significantly eliminates the existing conceptual uncertainty and inconsistency in the assessment of real and imagined threats and challenges facing our state, as well as ways and means of effective counteraction.The directions of increase of efficiency of legislative fixing of maintenance of economic safety of Ukraine are defined.
Tax on real estate, other than land
Authors: Brzezicki T. , Kornieiev P.
Published: October 2021

The study examines the mechanism of real estate taxation. The current state of their functioning in Ukraine is analysed in detail. Problems of legal and regulatory nature are also investigated. The main features that characterize this tax, both in Ukrainian and Polish legislation, are also described. In addition the feasibility of reforming the tax base in the Ukrainian legislation is analyzed. Analyzed the experience of foreign countries, and held a parallel to the functioning of the tax in Poland, as an example, one of Europe’s economically developed countries. This article focuses on tax on immovable property. The introduction of real estate tax in Ukraine has followed a difficult path. The authors emphasize that development, and global development, is not possible without the socio-economic development of the country. In the authors’ view, development must begin in the cities, namely with the effective formation of local budgets. Because the financial resources of the cities have a direct influence on the solution of social and economic problems. The problem of deficiency of financial resources of cities, is a frequent problem on the territory of Ukraine. Therefore, we consider it necessary to pay attention to the European practice of countries that have a rational approach to the redistribution of income, with the help of certain tax rates, or by applying the benefits provided by the legislation. Statistical data shows that property tax has been introduced in about 130 coun-tries, thereby providing a significant part of budget revenues. The study is written using the descriptive method on the basis of administrative court jurisprudence and tax law literature.

Published: October 2021

In this study, the optimum values of propolis ethanol extracts parameters were determined with the use of single and multi-objective optimization procedures. The euclidean distance approach was used in the multi-objective optimization process. Firstly, propolis was extracted using water with ethanol contents 40, 50, 60, 70 and 80% for 8, 10, 12, 16, 20 and 24 h. Then, total phenolic content (TPC) and ferric reducing antioxidant power (FRAP) activities of all extracts were determined. With the obtained data a prediction model was produced with the use of artificial neural networks (ANN), and optimization was performed using a moth-flame (MFO) algorithm. The best prediction models for the TPC and FRAP were observed in 2-5-1 and 2-5-1 network architecture with the mean absolute percentage error (MAPE) values, 5.126 and 2.451%, respectively. For maximum TPC, the extraction parameters were determined as ethanol content 57.5% and extraction time 13.56 h. To maximize FRAP, the optimized extraction parameters were ethanol content 72.03% and extraction time 18.04 h. The optimum extraction conditions for both maximum values of the studied assays were ethanol content 70.03% and extraction time 16.93 h. The study concluded that the integrated ANN and MFO algorithm system can be used in single and multi-objective optimization of extraction parameters. The established optimization model can save time, money, labor and energy.
Methodology for Forecasting Revenues from the Sale of Innovative Products in the Domestic Tourism Market
Authors: Shulhina Liudmyla
Published: October 2021

This article presents a methodology for forecasting the expected sales of innovative tourism products in the domestic market. The principles of the product life cycle concept and consumer behavior theory are taken as starting points for calculating the sales volumes of an innovative product as well as the rate of its penetration into the market. A method of measuring the level of consumer commitment to a travel agency and its offerings is posited, and the relationship between the structure of the target market and market activity in purchasing tourist products is demonstrated. Deep market segmentation is applied to take into account the behavioral peculiarities of individual subsegments (Loyalists Market, Sympathizers Market, Qualified Market, Finders Market, Serviced Market, Possible Market, Potential Consumers Market, Perspective Market). Formulas are proposed for calculating the volume of each of the identified markets. An improved and adapted model for the tourist market (by E. Rogers and F. Bass) is used to calculate the diffusion rates of domestic tourist products. This methodology of forecasting the expected sales of innovative tourism products in the domestic market is empirically confirmed based on data on the domestic tourism market in the region of Vinnytsiya, Ukraine.
