The study is aimed to apply remote sensing for purposes of land cover detection in researches of new territorial units in Ukraine. The example of forest detection using Landsat images is particularly presented in the study. While the study area presented by Korovyntsi amalgamated territorial community in the Sumy region. The forest classification and deforestation detection have been processed every 5 years from 1990 through 2020. The Landsat 5, 7, and 8 data from the United States Geological Survey (USGS) have been used for the research. The image choice depended on the date of data availability and reliability, but in time between mid-May to early July. The dataset of 11 total images was processed in the Harris Geospatial Solutions’ Environment for Visualizing Images (ENVI). The data were calibrated by using the ENVI Landsat calibration tool, the atmospheric correction applied by using the ENVI FLAASH tool, and seamless mosaicking was used for some periods with more than one image needed. Normalized Difference Vegetation Index (NDVI) is the basis for forest classification applied. Comparing remote sensing data from different years and different Landsat satellites allowed not just to identify vegetation type of forest, but also to detect land cover changes. The change detection has been analyzed in two ways. The first method was based on changes in classification status. The second method was based on a difference in NDVI values, while forest classification was held for masking out non-forest areas. The applied study observed ways of cost-efficient land use research for local communities. Those methods could be used by NGO’s, local activists, citizen scientists, local authorities for improving land use management with the most updated data, and identifying problems of deforestation, in the case of the study presented. Nonetheless, land cover change detection is not limited to forest cover presented in the study. Anyway, in the case of forest detection, Landsat images from different satellites could be compared and present historical data for the rural areas, which had a low research interest in the past, but it changed due to administrative reform in Ukraine and switching governance power to the local communities.
The article studies cultural expertise, importance of which grows within conditions of social and cultural transformations in modern society. It is underlines the features of cultural expertise for the analysis and solution of social problems. Cultural expertise is the basis for different projects: cultural, urban, artistic. Cultural studies mean cumulative knowledge for the expert knowledge. Expert assessments of processes and objects, which cannot be calculated, are based on their own judgments. Cultural expertise includes analysis of social reality: values, public opinion, interests, traditions and rules. All this must be expressed in quantitative terms. The question of the appropriateness for using axiological parameters is still open. It is stressed that the cultural expertise is important on different stages of the project making activity: planning, support, implementation, evaluation of its effectiveness. At the national level decision-making procedure should include the recommendations of academic experts for the objective information and understanding the results that will be achieved in the future. The procedure of cultural expertise legitimizes state decisions for the society. Cultural resources of cities and regions are assets for creative economy implementation. Cultural expertise of culture resources is a main component in the process of this realization on the national level. Cultural, educational and regional policies in Ukraine should consider cultural studies knowledge as basic for cultural expertise, which can be seen as an instrument in the context of social reality. An important task of the cultural expertise is the correlation between existing and desired image of the city with its cultural potential. The image is constructed purposefully; it represents the desired vision of the city and social relation to it. The successfully created image is capable to transform the idea and the mission of the city from the "model" to the program of activities.
The article is devoted to analysis of the artistic culturestructure. Artistic culture has developed its main structural elements that provide a certain logic of artistic thinking and artistic creativity and which are the basis of any work of art. These structural elements – rhythm, intonation, metaphor, myth (as a way of action organizing, as a prototype of composition), archetypes and archetypal symbols – are the main artistic means that "work" in all types of art, while defining the specifics (due to their dominance) of the each one of them.
The best results of researching archaeological sites in the coastal zone come from integrated interdisciplinary approach involving modern geophysical methods. The analysis of the archaeological material obtained during excavations of the “diamond-shaped tower” in the water area near the port quarters of Chersonese suggests that the structure was constructed in the ninth and tenth centuries AD. The results of research on this site show that from the ninth and tenth to the period from the late eleventh to the first half of the thirteenth centuries the sea level in Karantinnaia Bay rose by ca 1 meter. The data obtained by continuous seismoacoustic profiling were used to identify continuous changes of the coastline in result of transgression and accumulation of the bottom sediments in the section of the water area near the port district of Chersonese. The analysis of the built-up seismogeological sections and isobath map enabled the research group to identify 3 terraces and associated morphological elements indicating the location of ancient coastlines in different historical periods. A spatial relationship has been established between the archaeological objects found at the sea bottom and the position of the underwater terraces. A reconstruction of the ninth- and tenth-century coastline has been suggested according to the archaeological data. The location of the “diamond-shaped tower” and the construction remains discovered in 2019 on the same terrace suggests that the structures existed approximately at the same time. Electrical prospecting research using bottom electrotomography explored the sediment structure of marine terraces to a depth of 10 m. The research results have determined bottom anomalies corresponding to various stages of development of the coast of Karantinnaia Bay. An extended linear anomaly, located 40–50 m from the modern coast and hidden by a layer of bottom soil up to 3 m thick, most likely corresponds to the early period of the ancient city. The sea in this area is ca 2–3 m deep.

The significant change of missions and organization of the Armed Forces of Ukraine requires the deep transformation in the military education system and development military professional training, especially citizens’ training system development, inter alia ROTC students during last decades. The Action Plan on the Implementation of Defense Reform up to 2020 (Road Map of the Defense Reform) reveals the military education system’s effectiveness enhancement due to the improvement of training facilities, training exercises, NATO counties advanced training technologies and methodologies’ implementation in education. Reforms in the sphere of education and defense in Ukraine have revealed significant gaps in the system of physical training of student youth, development of which has not been kept abreast. The students do not form a self-assessment of their physical abilities and the need to master theoretical knowledge of physical fitness, as a result of which physical training, as a pedagogical process, doesn’t unclose the person’s education and socialization. The purpose of our research is to analyze the impact of university ROTC students’ physical fitness results on the state of their academic performance in combined arms training. The methods of analysis, synthesis and summarization of scientific research data of physical training problems and its legal framework were used during research. As a result of the research, the influence of insufficient physical fitness on the level of combined arms training of future reserve officers was revealed due to the negligence of both physical training legal framework of the student youth and ROTC. The research of low ROTC training level highlights that the current healthy recovery system of student youth physical training doesn’t provide for the necessary theoretical knowledge, methodic and practical skills’ development. The lack of hours for special physical training in the combined arms training of ROTC higher education establishments increases the negative effects of traditional physical training system’s absence on the state mobilization resources level.
