ANALYSIS OF THE DEFINITION "FORESITE OF TOURISM INVESTMENT ATTRACTIVENESS": ESSENCE AND CHARACTERISTICS
Authors:   Vinnytsia Institute of Trade and Economics of State University of Trade and Economics, Antoniuk Kateryna
Published: September 2022

Civilizational challenges of global scale, growing uncertainty of cyclical processes of economic development, the emergence of new, to some extent ambiguous, but powerful factors of socio-economic transformation, caused a slowdown in the dynamics of the national system of tourism. Under the conditions of global crisis phenomena, which are now characteristic of Ukraine's economic development, including the consequences of these phenomena, without a preventive response to external imbalances, socio-economic development is complicated. Therefore, forecasting of investment attractiveness of tourism, its investment as a component of the national economy is the basis for determining the prospects for socio-economic development of regions and the country on certain time horizons, which allows modeling scenarios of development of sub-units and regions in a dynamic market environment, which de facto is poorly predictable. The purpose of the article is to define the essence of the foresight, to project this definition to the field of tourism, by clarifying the definition of "investment attractive foresight", as well as the characteristics of the foresight methodology. The main research methods used in writing the article are comparative, cognitive generalization. The tense dynamics of management practice constantly complicates the field of solving applied problems by the subjects of activity. Scientific thought does not have time to investigate the problems that arise in a highly unstable business environment. Due to the growing dynamism and uncertainty of the external environment, the desire for stable development in the long term is significantly increasing, which actualizes the study of the formation of methodological foundations of tourism foresight. The method of forecasting or predicting future trends is now more relevant than ever is relevant today as never before, especially in the tourism industry under conditions of pandemic and war. Anticipation of investment attractiveness of tourism has practical value, as its application in practice allows to form strategic goals and develop preventive measures to implement the developed strategy.
UNEMPLOYMENT IN UKRAINE'S ECONOMY: COVID-19, WAR AND DIGITALIZATION

The article examines unemployment trends in Ukraine in the long and medium term, taking into account the impact of pandemic COVID-19 in 2020-2021, the Ukrainian-Russian war in 2022, the factors of the domestic labor market in 2002-2019, as well as the prospects for post-war reconstruction and digitalization of the country's economy. Using methods of correlation and regression analysis, the authors identified factors of long-term influence on unemployment in the pre-pandemic period. These include the inflation index, the number of university graduates, the number of arrivals and departures, the average annual minimum wage, and the number of economically active population. The resulting model substantiates that an increase in the inflation index, the number of arrivals to Ukraine, and the minimum wage reduces the level of unemployment in the country. On the other hand, an increase in the number of graduates and departures increases unemployment. The influence of the number of economically active population on this indicator is controversial and requires further research. Based on the identified factors, measures to reduce unemployment in Ukraine are proposed. Having assessed the impact of lockouts caused by the COVID-19 pandemic on employment, the dynamics of the unemployment rate in 2020-2021 was analyzed. It was substantiated that mass vaccination of Ukrainians against coronavirus disease and further reduction of COVID-19 incidence would help stabilize the labor market situation. However, in 2022 the invasion of the Russian Federation radically changed the government's priorities in the fight against unemployment. Therefore, this article analyzes current economic policies to stimulate employment and business recovery in Ukraine, as well as the potential macroeconomic consequences of military action. The COVID-19 pandemic and the war are identified as black swans that led to unpredictable changes in the labor market and accelerated the digitalization of the domestic economy. It is argued that the latter (in the sense of the development of artificial intelligence and quantum computers) will become another black swan in the long-term postwar period. On this basis, the main trends that will influence the Ukrainian labor market in the future (technological transformations, changes in economic and social models, increasing globalization, environmental changes) and the corresponding directions of digital transformations are analyzed.

Published: September 2022

One of the main components of natural resources of the agricultural enterprise is land or land resources. After conducting research and analysis of scientific publications, textbooks and manuals of scientific experts, as well as legislative and regulatory framework, the article found that there is no single definition of the essence of the concept of "land resources". On this basis, scientific approaches to the interpretation of the essence of the category "land resources" were summarized and their clarification was proposed. It was established that land resources can be interpreted as the main natural resource used in various sectors of the economy. The types of agricultural land, which include agricultural land: arable land, hayfields, pastures, fallows, perennial plantations, are substantiated. Also considered the main methodological approaches to assessing the effectiveness of the use of land resources of the enterprise, which allow for a comprehensive analysis, justify the conclusions about the effectiveness of agricultural land. The directions to improve the efficiency of land use by optimizing the structure of crops, the use of crop rotation, the creation of land cooperatives and improvement of the mechanism of land protection are formulated. Since the level of efficiency of agricultural land use will depend on the state of productive forces and the growth of the agrarian sector of Ukraine. Attention is paid to the issue of the concept of "land relations", which are an integral part of the economic and legal functioning of agricultural enterprises. In connection with the completion of land reform in Ukraine, the article defines the features of the regulation of land relations in the leading countries of the world. The experience of the United States of America, Canada, Great Britain, the Netherlands, Denmark, Switzerland and other countries is summarized. The peculiarities of functioning of the model of market turnover of agricultural land are analyzed, which led to the conclusion or the need to introduce a liberalized land market in Ukraine.

Authors:   Polissia National University, Haiduchok Tetyana , Tsehelnyk Nina ,   Polissia National University
Published: September 2022

In modern conditions the issue of forming reliable and qualitative information about financial and economic activities of business entities acquires particular importance. Constant changes in the system of bookkeeping and tax accounting lead to significant errors, which in turn increases the place and role of the guarantor of the reliability of financial reporting indicators – audit. This is one of the most important types of services, which is becoming more and more relevant. In the article the authors analyzed the situation in the market of audit services in the dynamics for 2016-2020. It has been proved that the current state of the market of audit services is, first of all, expansion of the range of services; growth of professional competence and practical skills of auditors. It was substantiated that the market of audit services in general is significantly affected by significant changes taking place in Ukraine. The demand for audit services is dictated by the conditions of the business environment: macroeconomic processes (related, for example, to the integration of the country into the world market), government actions and legislation, the intentions of owners, consumer behavior. A set of measures to improve auditing activities in the country is proposed. The path of European integration chosen by the country requires harmonization of domestic legislation in the field of auditing activities with the conceptual framework of international standards. According to the authors, firstly, it is advisable to create public control over the work of audit firms that conduct audits of enterprises of public interest. Secondly, it is necessary to create an advisory body of public control and to separate its functions from the Accounting Chamber of Ukraine. Audit activity in Ukraine in the context of European integration processes certainly needs further discussions and comparisons, which, as a result, will certainly accelerate the harmonization of auditors' activities with European norms and standards. For the foreseeable future, it is necessary to look for appropriate ways and activities that would facilitate a flawless audit of financial statements.
THE RISK OF A "BRAIN DRAIN" EFFECT IN UKRAINIAN SPECIALISTS WHO LEFT UKRAINE AFTER THE RUSSIAN INVASION BEGAN
Authors:   Sumy State University, Piven Daryna
Published: September 2022

The Ukrainian refugee crisis is one of the most significant humanitarian problems since the Russian invasion. Many highly educated people have fled Ukraine to find a safe place where they can safely continue their personal and professional lives. It follows that qualified Ukrainian workers may face the effect of "brain drain" in the countries of their current residence, which will have a negative impact on the economies of refugee-hosting countries and on the economy of Ukraine in the future. The object of the study is the labor market in the field of information technology, as it is a highly demanded and developing sector around the world. The conceptual category "brain waste" and its impact on the economy of the host country and the source country is considered. In order to make a forecast of the possible impact of the "brain drain" effect on Ukrainian IT-specialists in the most visited countries, the state of the Ukrainian IT-industry was analyzed according to the results of 2021. The author identified the reasons for the change of place of departure before and after the war. The professional level of IT specialists who migrated because of the war was determined. Countries were chosen based on the number of refugees from Ukraine and a survey conducted in March 2022. The article also presents a comparative analysis of the overall level of economic and digital/technological skills in the destination countries of emigrants from Ukraine and in Ukraine itself. The methodological basis of this study was a systematic approach to the study of theoretical aspects of the impact of "brain drain" on contemporary Ukrainian emigrants in order to clarify and define the essence of the basic concepts of "brain drain", systematize concepts, factors of emigration of highly qualified persons after the Russian invasion, and determine the possible future impact of "brain drain" on Ukrainian society. The methods used in this article are observation of survey results and analysis of secondary data. Collaborative projects between governments, universities, and businesses are suggested as a possible way to tap the economic potential of migrants. The main conclusions of the research are formulated and further ways of scientific research are outlined.

Published: September 2022

Factors that have a negative impact on the economy of the country were identified: geopolitical and financial and economic instability, inflationary fluctuations, migration processes, decline in financial stability of enterprises and their bankruptcy, etc. This necessitates the development of monitoring mechanisms, theoretical and methodological approaches and their practical implementation, aimed at the objective analysis and assessment of Ukraine's rating positions in the context of ensuring its economic security. This is an important methodological toolkit during the recovery and adaptation phase of the country's economy in the postwar period. The threats posed by hybrid warfare encompass all areas of the country's socio-economic development and negatively affect the level of its economic security. That is why the analysis of Ukraine's international rating positions should be comprehensive and aimed at identifying negative factors in order to develop appropriate programs and measures to minimize their impact and maintain the level of economic security of the state. The purpose of the study is to analyze the international ratings of Ukraine in the context of economic security. To analyze the rating positions of Ukraine in the context of economic security, a research panel containing general and specific international ratings and indices is used. The matrix of correspondence of international ratings and indices to the functional components of the economic security of Ukraine is constructed. A retrospective analysis of Ukraine's positioning in international rankings (ICT Development Index, Global Cybersecurity Index, Speedtest Global Index, ND-GAIN Country Index, International Property Rights Index, Fragile States Index, PowerIndex) was conducted. The methodological support for the calculation of these indices is considered. The results of the analysis show that most of the considered specific indices of independent rating agencies have a positive trend. The dynamics of the integral index of economic security of Ukraine for 2010-2022 is presented.
UKRAINIAN CROSS-BORDER MIGRATION UNDER MARTIAL LAW: A CHALLENGE AND THREAT TO THE FINANCIAL SECURITY OF THE STATE
Authors:   Sumy State University, Chorna Svitlana
Published: September 2022

Since the beginning of the invasion of Ukraine by the aggressor country, migration processes have taken on a mass character. First and foremost, people are trying to save their lives and their future. Migration because of the war affects various economic aspects: the labor force, the consumer market, domestic business, and national welfare. The dangers of migration are declared not only in Ukraine, but also in the host countries. Even if immigrants help replenish the basic factors of production, the cost of these resources becomes an additional burden on the system of social assistance, education, transportation, and housing. This increases the burden on the economic and financial security of the state. The article analyzes cross-border migration from Ukraine for military reasons, the trends of emigration processes and the impact on the financial security of the state. Statistical methods of obtaining information were used, a comparative analysis of data was carried out, the methodology of the research holding 4Service Group on the survey of Ukrainian emigrants was collected. Current statistics collected by the UN Refugee Agency are presented – more than 5.5 million Ukrainians are registered all over Europe. A comparative analysis of data from neighboring countries bordering Ukraine and other selected European countries was conducted separately for registered refugees from Ukraine and refugees officially registered for temporary protection in the host country. It turned out that safety was the most important factor during forced emigration for all Ukrainian refugees. The first condition for choosing a country to leave was the presence of acquaintances (relatives, friends). Some chose the country for its proximity to the border, others for its developed economy and more attractive social conditions. Justifies the need for an important task today for the Government of Ukraine, namely, it is necessary to make every effort to return the abandoned population, to stop this sufficient number of working-age population, which affects elements of the economy: the tax area, budget, business development, social processes.

Tracking the cellulolytic activity of Clostridium thermocellum biofilms
Authors: Dumitrache Alexandru , Wolfaardt Gideon M. , Allen David Grant , Liss Steven N. , Lynd Lee R.
Published: September 2022

Background
Microbial cellulose conversion by Clostridium thermocellum 27405 occurs predominantly through the activity of substrate-adherent bacteria organized in thin, primarily single cell-layered biofilms. The importance of cellulosic surface exposure to microbial hydrolysis has received little attention despite its implied impact on conversion kinetics.

Results
We showed the spatial heterogeneity of fiber distribution in pure cellulosic sheets, which made direct measurements of biofilm colonization and surface penetration impossible. Therefore, we utilized on-line measurements of carbon dioxide (CO2) production in continuous-flow reactors, in conjunction with confocal imaging, to observe patterns of biofilm invasion and to indirectly estimate microbial accessibility to the substrate’s surface and the resulting limitations on conversion kinetics. A strong positive correlation was found between cellulose consumption and CO2 production (R2 = 0.996) and between surface area and maximum biofilm activity (R2 = 0.981). We observed an initial biofilm development rate (0.46 h-1, 0.34 h-1 and 0.33 h-1) on Whatman sheets (#1, #598 and #3, respectively) that stabilized when the accessible surface was maximally colonized. The results suggest that cellulose conversion kinetics is initially subject to a microbial limitation period where the substrate is in excess, followed by a substrate limitation period where cellular mass, in the form of biofilms, is not limiting. Accessible surface area acts as an important determinant of the respective lengths of these two distinct periods. At end-point fermentation, all sheets were digested predominantly under substrate accessibility limitations (e.g., up to 81% of total CO2 production for Whatman #1). Integration of CO2 production rates over time showed Whatman #3 underwent the fastest conversion efficiency under microbial limitation, suggestive of best biofilm penetration, while Whatman #1 exhibited the least recalcitrance and the faster degradation during the substrate limitation period.

Conclusion
The results showed that the specific biofilm development rate of cellulolytic bacteria such as C. thermocellum has a notable effect on overall reactor kinetics during the period of microbial limitation, when ca. 20% of cellulose conversion occurs. The study further demonstrated the utility of on-line CO2 measurements as a method to assess biofilm development and substrate digestibility pertaining to microbial solubilization of cellulose, which is relevant when considering feedstock pre-treatment options.
Optoacoustic Detection of Thermal Lesions
Authors: Arsenault Michel G. , Kolios Michael , Whelan William M.
Published: September 2022

Minimally
invasive thermal therapy is being investigated as an alternative
cancer treatment. It involves heating tissues to greater than 55°C over a period of a few minutes,
which results in tissue coagulation. Optoacoustic (OA) imaging is a new imaging technique that involves exposing tissues to pulsed light and detecting the acoustic waves that are generated. In this study, adult bovine liver tissue
samples were heated using continuous wave laser energy for various times, then scanned using an optoacoustic imaging
system. Large optoacoustic signal
variability was observed in the native tissue prior to
heating. OA signal amplitude increased with
maximum tissue temperature achieved,
characterized by a correlation coefficient of 0.63. In this study we show that there are detectable changes in optoacoustic signal strength that arise from tissue coagulation, which demonstrates the potential of optoacoustic technology for the monitoring of thermal therapy delivery.
Analysis of Ultrasound Backscatter from Ensembles of Cells and Isolated Nuclei

Published: September 2022

We have previously shown that the intensity of the ultrasound backscatter from cells ensembles undergoing apoptosis increases and shifts in their normalized power spectra are detected when compared to the backscatter from non-apoptotic cells. The etiology of these changes is unknown. During apoptosis many cellular changes occur, perhaps the most striking being the condensation and subsequent fragmentation of the cell nucleus. In this set of experiments have exposed either whole Acute Myeloid Leukemia (AML) cells or nuclei isolated from AML cells to different ionic strengths known to induce specific and reproducible cellular and nuclear changes. Ultrasound images and rf backscatter data were collected and analyzed at the different ionic strengths, and electron micrographs were made. Exposing cells to higher ionic strengths increased the ultrasound backscatter by 12 dB, but exposing the nuclei to the same experimental conditions decreased the backscatter by 23 dB. Furthermore, while the spectral slopes of the rf backscatter were similar for cells and nuclei at physiological saline, at increased concentrations the slope increased for the nuclei but decreased for the cells. The paper discusses the implications and significance of the findings. In conclusion, disruptions in cell and nuclear structure induced by exposure to strong ionic environments can greatly alter the ultrasound backscatter signal characteristics.

Information and communication technology is an important part of the implementation of learning activities. It can be seen through ICT that the implementation of learning can take place dynamically and can be carried out at any time, regardless of space and time. Therefore, ICT is considered necessary to be optimized as an integral part of the learning process in an effort to implement the transformation of ICT-based education to meet the needs of students. This study aims to describe the form of educational transformation by optimizing the use of ICT-based learning media. This study uses a literature study technique with data sources, namely various relevant literature on educational transformation, ICT-based learning media, and 21st-century competencies sourced from books and scientific articles. The results of the study indicate that one of the efforts to support and succeed in the transformation of education can be made through the use of various ICT tools in learning, be it primary, secondary, or even tertiary education. This optimization is considered necessary considering that the impact tends to lead to supporting facilities in order to achieve 21st-century learning goals and competencies. Through the results of this research, it is hoped that it will serve as a basis for educators and policymakers to not hesitate in optimizing ICT for teaching and learning activities.
Thoughts for the New Librarian

After spending over a decade as a public-school educator and subsequent time as an administrative assistant, I embarked on what is essentially my third career as a librarian. Since being hired at an academic library in the summer of 2021, I have–for the most part–settled into my role as Instructional Librarian for Distance and Online Learning. At an age where most librarians are starting to eye the exit, I am “learning the ropes.” After a year, I still have a lot to learn; however, there are some areas where I believe I can offer insights for those just entering the profession. In this column, I will offer three pointers for how to make a new librarian’s first year less overwhelming.
The Storied Matter of the Greenwood in the More-Than-Human World
Authors: Hogue Jason
Published: September 2022

This article brings posthumanist and new materialist perspectives to bear on the enmeshment of “the human” with and among the materialities of the greenwood in early Robin Hood ballads, focusing on Robin Hood and the Monk. The article suggests that medieval outlaw tales offer ecocriticism a site within medieval literature that not only challenges and deconstructs prevailing notions of human exceptionalism and anthropocentrism, but also portrays the medieval forest as a storied place, what Wendy Wheeler calls a “meaning-bearing field of agency,” imbued with interacting stories of both animate and inanimate life, such as the deer hunted by Robin and his outlaws, and also less obvious beings, such as the famous Trysting Tree.

When patients have mild microcytic hypochromic anemia with slightly increased hemoglobin (Hb) A2 fraction, the most likely diagnosis is beta-thalassemia heterozygosity. But herein we found a patient who had all these hematological parameters but did not have beta-thalassemia heterozygosity. He was a 14-year-old Thai who presented with fatigue and heat intolerance for 2 weeks. His physical examination revealed mild diffuse enlargement of thyroid gland. Blood tests showed Hb 120 g/L, mean corpuscular volume (MCV) 72.1 fL, mean corpuscular hemoglobin (MCH) 23.3 pg/cell, free triiodothyronine (FT3) > 20 pg/mL, free thyroxine (FT4) > 5.0 ng/dL, thyrotropin < 2.5 mIU/L, serum ferritin 51.3 µg/L, Hb A2 3.8%. Besides primary hyperthyroidism, he was diagnosed with beta-thalassemia heterozygosity. After being treated with antithyroid drug for 6 months, his blood tests showed subclinical hyperthyroidism, Hb 146 g/L, MCV 83.3 fL, MCH 26.3 pg/cell, Hb A2 3.0%. Not only the thyroid hormones levels but also the Hb concentration, MCV, and the Hb A2 percentage became normal. Due to this inconsistency, the DNA analysis for beta-thalassemia genes was performed and found negative for numerous common and rare beta-thalassemia genes meanwhile beta-globin gene sequencing appeared normal. It should be concluded that hyperthyroidism could induce slightly elevated Hb A2 percentage and mild hypochromic microcytic anemia in a normal individual, leading to the misdiagnosis of beta-thalassemia heterozygosity. In other words, Hb analysis should not be performed during hyperthyroidism and it should be delayed till achievement of the euthyroid stage.

The article deals with economic aspects of integration ties in dairy cattle breeding development of Ukraine. Mutually benefcial integration of agricultural organizations with other market players signifcantly improves their economic stability. In addition to system-wide factors that determine agro-industrial integration, dairy subcomplex has a number of specifc features that determine occurrence and development of integration processes in the feld of production, processing and sales of milk. It is proved that a cooperative form of ownership may compete with joint stock in a global scale in dairy subcomplex mainly due to the fact that vertical cooperation has prevailed historically in countries specializing in milk production, which allows farmers to manage income from the dairy products sale. High dairy business concentration provides cooperatives with the opportunity to use the latest processing technologies, to pursue ﬂexible commodity policies, to get access to interregional and international markets, to combine dairy business with logistics and other important services, to reduce the negative inﬂuence of seasonal ﬂuctuations in milk production. The characteristic feature of the relationship between domestic milk producers and processing enterprises is its non-cooperative integration, which is based on contractual arrangements. To summarize the contracting type of dairy factories integration with agricultural producers, it should be noted that in this rather simple form of economic relations involves opportunities for further development. It is established that the low activity of establishing and dairy cooperatives running is inefcient due to low activity rural residents who farm cows. In our opinion, there are no prerequisites for agricultural cooperatives establishment in most regions since most of the population have only one cow and is focused on its self-provision. We believe that dairy-grocery cluster based on the principles of mutually benefcial long-term partnership between the subjects is the driving force in ensuring economic growth in the examined industry. It creates conditions for employment growth in the region, proposals for high-quality dairy raw materials and safe milk products. In general, this will contribute to the sustainable development of dairy cattle breeding enterprises in the region and other participants of the cluster association.

The modern olericalture development needs special attention to self-sufciency in domestic products under the war conditions in 2022. It has some relation to garlic production as well. The garlic has been supplied by China. It is possible to compensate the garlic shortage in Ukraine by the implementation of the hybrid cultivars of domestic and foreign breeding in garlic production. However, the winter garlic is considered to be a vegetable that is poorly adapted to weather changes and it doesn’t show its biological potential. The domestic variety introduction of garlic from one local region to another requires an additional research. The research has been done in the experimental feld of Bila Tserkva NAU (The Right Bank Forest-Steppe of Ukraine). 65 cultivars of winter and local garlic have been studied. The test samples include garlic that has been delivered from Vinnytsia, Dnipro, Kyiv, Kirovohrad, Chernihiv, Cherkasy regions. The variety Prometheus has been taken as a control sample. This variety has been bred in Uman National University of Horticulture. The research has been done in accordance with the olericulture and melon growing research method. In 2020 and 2021, the weather conditions were good for plant growth and formation of the winter garlic yield. The plant density was 357 000 plants per ha. On average, in 2020 and 2021, the cultivar Lubasha, Ayder, IOB0017 had the biggest garlic heads in diameter (Lubasha – 5.5 cm, Ayder – 5.2 cm, IOB0017 – 5.2 cm). The samples of Duchess, Lubasha, Ayder had the highest average weight (Duchess – 55 g, Lubasha – 68 g, Ayder – 65 g). The cultivars Lubasha and Ayder had given the biggest yield of winter garlic heads (Lubasha – 20,3 t/ha, Ayder – 19,4 t/ha). The biggest amount of marketable garlic heads had been noticed in the varieties Lubasha, Duchess, Ayder and in the cultivars IOB00117, IOB00003 from the Institute of Vegetable and Melon growing, where this result ranged from 81 % to 84 %. As a result of the conducted research, the best cultivars have been identifed. The samples of Lubasha, Duchess, Ayder varieties have the biggest garlic heads in diameter, mass and in the amount of yield. Also, Lubasha, Duchess, Ayder, IOB0017 and IOB00003 have the biggest marketable yield amount.
Key words: cultivars, local forms, winter garlic, weight of the bulb, yield productivity, marketability.

The article presents the results of research on quality formation of berries and jams of different of chokeberry varieties. It was found that the content of organic acids, protein, fber and carbohydrates in chokeberry of Kutno variety was signifcantly lower compared to Belder variety. The biochemical component in jam differed from that of fresh berries. Thus, fat content was absent. The content of organic acids was 2.2–2.8 times, the protein content – 2.0–3.0, the fber content – 2.3–2.9, the water content – 3.7 times lower than that of fresh berries. However, the carbohydrate content was 6.8–6.9 times higher than that of fresh berries depending on chokeberry variety. The higher content of carbohydrates in jam is due to the fact that sugar was added during its preparation. In fresh chokeberries of Kutno variety, the content of vitamin A, B3, E and C was signifcantly lower compared to Belder variety. Of the studied vitamins in fresh berries, vitamin C content was the highest – 11–14 mg/100 g depending on the variety. Vitamins B1 and B2 content did not change depending on the variety. It should be noted that this indicator was the same in fresh berries and jam. Vitamin A content in chokeberry jam was 2.5–3.2 times, B3 – 1.7–1.8, E – 2.2–2.5, C – 2.8–3.7 times lower depending on the variety. It was found that vitamins C (10–13 %) and E (7–10 %) provide the greatest daily intake of 100 g of fresh berries depending on chokeberry variety. Jam integrated score was lower and amounted to 3–5 and 3–4 %, respectively, depending on the variety. The lowest daily intake is provided by 100 g of fresh berries with vitamin B1 – by 1%. The integrated score for vitamins B2, A and B3 was 2–5 % depending on chokeberry variety. Jam indicator was only 2–3 %. Fresh chokeberry best meet the daily needs of the human body with fosphorus –by 10 % The integrated score for magnesium and iron was 6–9 % depending on the variety. At least this need is met by fresh chokeberries with sodium – by 0.1 %. Integrated score for calcium and potassium was 3–4 %. The greatest daily need of 100 g of jam is satisfed by iron – by 7–8 %. The least – by sodium – by 0.1 %. Integrated score for calcium, potassium, magnesium, and phosphorus was 1–6 % depending on chokeberry variety.
