Item Assessment of lost benefits for nature conservation areas and objects due to war in the post-war recovery system of the country(2023) Horoshkova, Lidiia; Vasyl'yeva, O.; Antoniuk, D.; Antoniuk, K.; Horoshkov, S.; Tarasenko, O.The study involves an analysis of the existing "Methodology for Determining Damage and the Extent of Losses Incurred by Enterprises, Institutions, and Organizations of All Forms of Ownership Due to the Destruction and Damage to Their Property as a Result of Armed Aggression by Russian Federation, as well as Lost Benefits from the Inability or Obstruction of Economic Activity Implementation" for its application in assessing the lost benefits of the Azov-Syvash National Natural Park. Considering the non-profit nature of the institution’s activities, proposals are developed to improve the Methodology by creating an algorithm for assessing lost benefits for non-profit organizations engaged in economic activities and of significant societal/state importance. Determining the extent of lost benefits was carried out using the following estimation procedures: analysis and determination of the compounding period within which the lost benefit from the asset (property) is considered; calculation of the annual amount of cash flows and conversion into a monthly amount for the entire compounding period; justification of the components of the compounding rate and its determination; determination of the future value of cash flows at the end of the compounding period through compounding these cash flows.Item Ecological risks of the impact of war on nature reserves in Ukraine (using the example of the Azovo-Sivash National Nature Park)(2023) Horoshkova, Lidiia; Skrynchenko, K.; Menshov, Oleksandr; Maslova, O.; Korniichuk, Y.Since the beginning of Russia’s full-scale invasion of Ukraine and the occupation of the peninsula, control over the jackal population has ceased. The increase in the number of jackals may be contributing to the predation on young deer, indirectly supported by the increase in grassland cover. Deer and mouflon are not attractive prey for jackals due to their size, so their populations remain stable, as does the level of shrubs. These changes create conditions for potential risks to the ecosystem, including the possible decline in the population of certain ungulate species or even their complete disappearance. The situation requires immediate attention and active measures to restore the ecological balance. Natural reserves like the Azovo-Sivash National Nature Park require additional monitoring and management to preserve species diversity and ecosystem stability. This may include the restoration of predator population control programs and research into their impact on ungulate populations to avoid the negative consequences of this dynamic. The methodology involves processing raster images of objects from different layers of the Dynamic World V1 subprogram, calculating pixel loads for specific types of objects using built-in program layers, and transforming the obtained data into ratios of actual object areas to the total area of the territory. Monthly averages were calculated for each object type. The observation period was selected from December 2015 to April 2023, taking into account the maximum capabilities of the Dynamic World V1 program for data reproduction.Item Magnetic Properties of Sloping Soils: Methodological Challenges(2023) Kruglov, O.; Menshov, Oleksandr; Horoshkova, Lidiia; Kruhlov, B.The application of magnetometry in service provision of agricultural production is a very promising market. However, a number of methodical tasks stand in the way of active introduction of soil magnetometry. One of them is taking into account the impact of anomaly-forming processes, among which there is the alternation of washout - washout zones under the action of erosion processes. This paper investigates the spatial distribution of magnetic susceptibility of the soils of the sloping agricultural landscape and its relationship with key agronomic characteristics. The most significant deviations are characteristic of the first third of the range of organic carbon content values. Such values are characteristic of the lower parts of the landscape, with the most pronounced manifestations of washout.Item Monitoring and modeling of infrastructure indicators development of united territorial communities(2022) Horoshkova, Lidiia; Khlobystov, Yevgen; Shvydka, S.; Menshov, Oleksandr; Tarasenko, Denys; Sumets, A.A study of the dynamics of state support for infrastructure development of UTC, development expenditures (capital expenditures) and the effectiveness of the current mechanism for calculating the infrastructure subvention on the example of Zaporizhya region and identified the relationship between infrastructure subvention and development expenditures (capital expenditures). It is established that the current mechanism for determining the size of the infrastructure subvention, when it is determined depending on the size of the rural population and the area of UTC is ineffective. It is proved that it is necessary to assess the parameters of sustainable development of OTG not only by traditional components, which are economic, environmental and social, but also by the infrastructural component. For this purpose, an integrated indicator of sustainable infrastructural development of each individual UTC, district or region is proposed, which would allow comparing OTG indicators not only within a district or region, but also between regions of Ukraine. Its definition is carried out using the apparatus of fuzzy set theory.Item Monitoring and modelling of environmental pollution in the Southern regions of Ukraine(2022) Khlobystov, Yevhen; Horoshkova, Lidiia; Varianichko, Valeriia; Skrynchenko, K.; Horoshkov, Stanislav; Tsurika, L.To model the situation with the emissions of air pollutants taking into account the identified trends of the emissions of air pollutants and the main impact factors, the approximation, smoothing dynamics and trend line of Microsoft Excel were applied to determine regression equations and check significance and accuracy of the built models. Statistical modelling of air pollution safety limits was applied as well. To determine the factors affecting emissions of air pollutants, the index of cross-correlation was used. It has been proven that the regional ecological condition impacted by the emissions of air pollutants depends on the priority types of economic activity.Item Regularities of changes in the recreation ecosystems’ quality parameters in space(2022) Arkhypova, Liudmyla; Korchemluk, M.; Horoshkova, Lidiia; Khlobystov, Yevhen; Stakhmych, YuliiaOur study of the Danube hydro-ecosystems of the Carpathian region using of the integrated natural water quality assessment resulted in obtaining the functional dependencies between quality indicator and altitude. For the first time, the regularities of changes in the ecosystems’ quality parameters in space were established by means of developing functional dependences among the ecological standard values of the composite quality indicators of natural waters and the river length and terrain altitude, and performing the statistical processing of the database containing the results of the quality monitoring observations of the upper reaches of the Danube ecosystems in the Ukrainian Carpathians for the period from begin 21 st. The obtained dependencie and map can be used for the Carpathian region as the territorial background standard values of the ecological state indicators of basin ecosystems, which will help to scientifically substantiate the ecologically safe values of the anthropogenic pressure.Item Risk management and lost profits calculations of business entities(2022) Horoshkova, Lidiia; Antoniuk, D.; Vasyl'yeva, O.; Markova,S.; Filipishyna, L.The methodology of lost profits assessment for a business entity as a result of military actions (aggression) has been developed. The methodology includes calculation of business entity`s main operational indicators (groups of indicators) based on the analysis of its financial, accounting and tax reporting. It also takes into account the peculiarities and types of business activity when calculating the lost profits. When calculating the lost profits, it is advisable to take into account the specifics of doing business in various sectors of national economy. Qualified personnel loss and additional training costs play an important role in manufacturing; service sector could make no gain without damage or property loss; agricultural sector is the most vulnerable sector in terms of lost profits caused by the war, as well as the most complicated field to calculate the lost profits due to the large number of impact factors to be taken into consideration.Item Soil magnetic properties of the landslide site in O. V. Fomin Botanical Garden(2023) Menshov, Oleksandr; Horoshkova, Lidiia; Kruglov, O.; Andreeva, O.To perform landslide susceptibility prediction, it is important to select appropriate mapping unit and landslide-related conditioning factors. Magnetic method is low cost and rapid instrument for the landslide and soil erosion identification. An example of the application of the magnetic methods for the local prediction of possible landslide activation was performed at the territory of the Alpine hill of O. V. Fomin Botanical Garden of Taras Shevchenko National university of Kyiv. The results of the soil magnetic studies demonstrated the redistribution of the soil genetic horizons. The confirmation is the visible difference from the normal natural conditions according to the magnetic susceptibility (MS, χ) values. The anthropogenic pollution was registered too. The values of MS are 1.5–2 times higher comparing with the natural chernozems of Kyiv region.Item Soil sampling and magnetic susceptibility determination in soil science: methodological aspect(2022) Kruglov, O.; Menshov, Oleksandr; Horoshkova, Lidiia; Tonkha, O.; Andreeva, O.; Kruhlov, Bohdan; Zhuravel, O.The study is dedicated to the numerous methodological problems that arise when applying the magnetic susceptibility measurements of soils for the agrarian application. The experiment was carried out for the chernozem soils of the Kharkiv and Poltava regions. Problems in the sampling planning are related to the main tillage processes. The temporal and spatial parameters as well as the sampling depth were analyzed. It has been shown that the use of soil magnetic susceptibility (MS) has a high potential in determining soil inhomogeneities. The first of all, MS is relevant in the implementation of the concept of precision agriculture, where it has market advantages over traditional methods.
