- In this article we review the legal regulation of an obligation to self-isolate in Ukraine. For the period from 22 April 2020 till 22 June 2020 four groups of persons were obliged to self-isolate due to COVID-19. These groups are: persons diagnosed with or suspected to have COVID-19, persons that have been in contact with those diagnosed with COVID-19, those who consented to self-isolation when entering Ukrainian borders instead of being placed in special facilities, and everyone aged 60 and above. In the article, we analyse whether an obligation to self-isolate should be viewed as interference with the right to liberty and security or with the freedom of movement for each of these groups. The analysis focuses on the Constitution of Ukraine and the European Convention for the Protection of Human Rights and Fundamental Freedoms. We also study circumstances when the above-mentioned rights can be limited lawfully in cases related to spread of infectious diseases, such as COVID-19. This article questions if the actions of Ukrainian government and existing legal regulation of obligatory self-isolation meet the requirements of lawful limitation of rights.

- The practical task of economics lies in applying the methods of substantiating its decisions. For economics, the main method is the modeling of economic phenomena and processes and, above all, mathematical modeling, which has been stipulated by the presence of stable MATHEMATICAL METHODS, MODELS AND INFORMATION TECHNOLOGIES IN ECONOMY Issue I (81), 2021 117 quantitative patterns and the possibility of a formalized description of many economic processes. The economic-mathematical model contains a system of equations of linear and nonlinear units that promote a mathematical description of economic processes and phenomena, consists of a set of variables and parameters and serves to study these processes and control them. Dynamic models of the economy describe it in development, as well as provide a detailed description of technological methods of production. Mathematical description of dynamic models is carried out with the use of a system of differential equations (in models with continuous time), difference equations (in models with discrete time), as well as systems of algebraic equations. It is important that the investigation of various economic issues has led to the development of the mathematical apparatus. In linear algebra, productive matrices are caused by the studies of intersectoral balance, whereas mathematical programming arose in the course of researching the optimal plan for the distribution of limited resources. In a similar way, there emerged the theory of economic indices and econometrics, the theory of production functions and the theory of consumption, the theory of general economic balance and social welfare, the theory of optimal economic growth. The paper under studies deals with the dynamic economic behavior of two competing objects, whose mathematical model is a nonlinear nonlocal problem for a system of ordinary differential equations with variable coefficients and argument deviation. The dynamic mathematical model is based on the assumption that the volume of output of both firms is determined by such factors on which output depends linearly. The model under discussion includes nonlinear factors, which describe the level of distrust of the competitors and depend on the time of observations and production volumes in previous moments, because the latter significantly affect the production activities of the firm. Such mathematical models are called time-delayed models.

- This article describes the creation of a more generalized system of simultaneous equations for forecasting the level of sales depending on advertising campaigns on different channels and other factors. RStudio (R programming language) and Google Colab (Python programming language) environments describe the creation of a model based on real data of a product. The Hausman specification test was applied to determine the model estimation method. As a conclusion, the indicators of advertising campaigns turned out to be endogenous variables, which indicates the importance of using the 2MNK method. It was found that the volume of advertising is the cause of the volume of sales according to Granger, which cannot be said about the reverse assumption - the causality of the volume of advertising from sales according to Granger. The ”depth” of lags is also determined, namely, one lag for both advertising channels. The dependence of sales volumes on various factors, including product distribution, the price index, the influence of advertising and its lags, and the influence of competitors’ advertising activities, was evaluated. The coefficients of the resulting more generalized system of simultaneous equations were estimated using the two-step least squares method. All statistical indicators testify to the adequacy of the model. Performance indicators (ROI - return on investment) of advertising campaigns showed that advertising both on television and on the Internet is profitable for the company’s product in question. The relevance of this article lies in the creation of a more general system of simultaneous equations with the inclusion of a product sales forecast model taking into account the influence of advertising.

- The war in Ukraine that began in February 2014 with the annexation of Crimea and escalated in February 2022 to the extent unseen in Europe since the World War II, cannot be adequately comprehended without taking into consideration its religious dimension. This dimension was correctly identified by the patriarch of Moscow and all Russia Kirill as “metaphysical.” This paper explores some aspects of the metaphysics of the Russo-Ukrainian war. It also tries to explain how and why the Russian Orthodox Church has contributed to it.

- У статті розглядається Конференція ООН з навколишнього середовища 1972 року в Стокгольмі, яка стала першою, що визначила питання охорони навколишнього середовища як головну глобальну проблему. Метою статті стало створення додаткової дискусії стосовно історико-правових особливостей та сприйняття сталого розвитку як на глобальному рівні, так і в Україні. Цьогоріч, 2022 року, з нагоди 50-річчя Конференції ООН відбулася міжнародна зустріч Стокгольм+50, що і актуалізує тематику дослідження та дозволяє вшанувати ювілей знаменної події. У статті розкривається важливість проведення Стокгольмської конференції 1972 р., а саме, – неоднозначність концепції «людське навколишнє середовище», що дало учасникам можливість як сформулювати свою соціальну та наукову позицію для глобальних взаємодій, так і дослідити драйвери для подальшого юридичного сприйняття в інших країнах світу, зокрема і в Україні. У статті згадуються тогочасні геополітичні перешкоди для продуктивної співпраці, такі як Холодна війна, Карибська криза, бойкот країн Радянського Союзу і Східного блоку, тощо. Незважаючи на це, Стокгольмська конференція стала ареною для глобальних дискусій, відбулось уніфіковане сприйняття різними сторонами поняття людського навколишнього середовища та з’явилась правова основа для подальших дій у цій сфері. У статті розглядаються позиції зарубіжних та українських науковців стосовно значення проведення конференції, аналізуються дані діджитал-бібліотеки ООН (United Nations Digital Library System) з теми ʼСтокгольм 1972ʼ, перебіг підготовки до проведення конференції, розкривається її вплив на подальший розвиток юридичних норм у цій сфері. Розглянувши тогочасні нормативні акти України у їх синхронному порівнянні з європейськими нормами, автор доходить до висновку, що конференція у Стокгольмі 1972 р. стала драйвером до подальших змін у глобальних діях міжнародного співтовариства у сфері захисту навколишнього середовища.

- Загальне уявлення про соціальну користь від реалізації концепції сталого розвитку має формуватися попередньо з розуміння її природи та сутності терміна через правильний переклад і сприйняття. Відсутність еквівалентного терміну sustainable development в українській мові ускладнює не лише переклад цієї мовної конструкції, а й її розуміння та осмислення як законодавцем, так і суспільством. Google Trends–це веб-додаток, який аналізує популярність пошукових запитів у пошуку Google у різних регіонахта на різних мовах. Цей інструмент було використано для емпіричного аналізу сприйняття концепції сталого розвитку в Україні та її порівняння зі світовими запитами у цій сфері. Результати веб-пошуку концепції сталого розвитку в Україні з 2004 по 2021 роки були проаналізовані у двох категоріях, обраних із варіацій Google–(1) загальний пошук та (2) законодавчий. Кожен пошук проаналізовано за двома індикаторами, які доступні на цій платформі: (1) динаміка пошуку, (2) подібний пошук. Аналіз цих даних та порівняння пошукових запитів у Google Trends щодо сталого розвитку в Україні ілюструє загальний низький рівень обізнаності та зацікавленості у цій темі та актуалізує необхідність подальших досліджень у сфері забезпечення сталого розвитку в Україні.

- Despite the active research of Jurassic system deposits of Donbas during the last two centuries theissue of their stratigraphy principles is still debatable. Theauthors` analysis of the available scientific material revealedaconflict between the normatively established requirement to rely on lithostratigraphy duringthe sediment research, andthe fact that the existing common system relies on biostratigraphy. This contradiction could be solved by the study oflithostratigraphic units of the Donetsk Jurassic deposits. Therefore, the purpose of the article was to research the Kozhu-linska formation, establish its composition and describe its main features. The Lower Jurassic deposits from the outcropsnear the village of Kamyanka (Izyum district) were studied, since the studyable stratotypes of most of the Jurassic strata,which are well exposed in the studied area, are available in this area.Material and methods. The scientific search was based on the analysis of literature, results of previous drilling andmapping works, as well as own field, laboratory and analyticalstudies. Clay samples were taken from different strati-graphic levels of the formation and from different lithologicalvarieties. Laboratory research was carried out in two direc-tions: using an electron microscope and a spectrometer to detect the material composition of clays. A palynological anal-ysis of these deposits was also carried out, namely, stratifieddeposits with the help of microphytofossils, including, forthe first time, according to the orthostratigraphic group – dinocysts.Results and discussion. The results showed that the Kozhulinska formation was mainlyrepresented by shaly clays(gray, dark gray, sometimes blue-gray) that contained relatively thin layers of sandstones. The main mass of clays con-sisted of hydromicas, with an insignificant content of montmorillonite, and an even smaller amount of kaolin. The layersof quartz sandstones cemented withclay material were separately traced along the strike.Paleontological remains in the clays of Kozhulinska formation were rare. Palynological groups are mainly repre-sented by pollen and spores, as well as remains of dinophytes,green algae and acritarchs. According to paleoalgologicalanalysis, the sediments of the Kozhulinska formation are datedfor the first time.Stratigraphy. Kozhulinska formation is represented by a fairly uniform layer of montmorillonite clays of hydromicacomposition. The clays are mainly siltstone, but there are, especially in the lower part, washed clean varieties. It is im-possible to divide the formation into sub formation based on lithological features. According to biostratigraphic data,deposits are divided into Plinsbachian, Toarian and Aalenian.Paleogeography. At the end of the Early Jurassic and the beginning of the Middle Jurassic era, the territory of theKamianska area was a low-lying part of the seabed that was drained during low tides. The land that surrounded it wasalso low-lying and almost did not supply detrital material, however, there is a regular removal of plant detritus. The sourceof the terrigenous material was the sedimentary complexes of the Donetsk Ridge. Features of the chemical compositionof the world are a significant amount of iron (siderite, ocher,chamosite) and the absence of calcium and magnesiumcarbonates. At the end of the early Aalene, this unstable basinfinally regresses, which leads to the accumulation of apowerful subaerial pack of sandstones, which weigh and border the cores of anticlines - elevated areas of the bottom orsmall islands.
