How Physicians and Patients Interact with Electronic Health Data: A Human-Computer Interaction Perspective
Authors: Zakreuskaya Anastasiya
Published: June 2023

The collection and use of personal data is increasing and new developments in Big Data Analytics allow for innovative applications. Recent developments in healthcare, such as the proposal of the European Health Data Space, point towards a more data-driven future of diagnostics and therapy. These developments lead to new challenges, especially in how to design interfaces that support clinicians to navigate through these growing amount of data and new innovative algorithms. Therefore, this work aims to illustrate current experiences of physicians and nurses with health data, investiate possible solutions for data-driven interfaces and ultimately discuss strategies to include new data-sources, such as self-tracking data or patient reported outcome measures.

Published: June 2023

High cholesterol is a risk factor for developing Atherosclerotic Cardiovascular Disease. Poorly designed health data displays cause an undue cognitive burden on clinicians. Simplified line graphs (i.e., sparklines) could support efficient cognitive processing and interpretation of lipid panel results. Clinical concepts for cognitive tasks assessing low-density lipoprotein laboratory results were analyzed according to their internal representations and data scale types. A sparkline external representation aligns more closely with the internal representations for mental tasks associated with identifying abnormalities and assessing trends compared to traditional tabular displays. By simplifying the health data display with sparklines, faster cognitive processing is theoretically supported.

Authors: Naz Saima , Chatha Ahmad Manan Mustafa , Durali DANABAS  , Arshad Aqsa
Published: June 2023

In late 2019, a new coronaviridae family member officially designated as “Severe Acute Respiratory Syndrome Coronavirus-2” (SARS-CoV-2) emerged and began to spread intensely, worldwide. Its rapid spread was declared as a pandemic by the World Health Organization (WHO) in March 2020. Within the coronaviridae family, SARS-CoV-2 is the third highly pathogenic virus that infects human beings, following the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV). In this review, the molecular basis for the origin, mode of action, invasion, and organization of these viruses are discussed by using various models.  Moreover, the transmission pathways, replication mechanisms, and diagnostic strategies of these viruses are also discussed. The molecular basis of SARS and MERS helps to understand their infection patterns, pathogenic mechanisms with anecdotes on their diagnosis, and future directions. Expectedly, this study would serve the purpose of being a reliable source of information to scientists, clinicians, as well as the general public.

Published: June 2023

Coronavirus disease (COVID-19), a viral disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected the entire world, killing approximately 5 million people. The COVID-19 pandemic has raised several questions for the researchers to answer in terms of therapeutics and proteins. Several vaccines against SARS-CoV-2 are now available all around the world. These vaccines showed significant efficacy in clinical trials. However, some individuals become affected by COVID-19 even after vaccination. This study aimed to determine the effectiveness of different vaccines being used in Lahore, Pakistan on the basis of symptoms and relapse. This cross-sectional study was conducted at the Institute of Public health, Mayo Hospital, Lahore, Pakistan. Samples collected from September 18, 2021 to October 18, 2021 were included in the study. The nasopharyngeal swab samples of patients were collected and put in the viral transport medium (VTM) to safely transfer them to the diagnostic lab. Real-time PCR was used for the identification of the virus. The study found that some vaccinated people were affected by SARS-CoV-2 infection; however, the prevalence of the infection in such people was low (9.21%, 93 out of 1010). It was observed that most of the vaccinated patients remained stable. The authors did not commemorate any deaths among them. It was concluded that the vaccines that are currently available and being used have significant efficacy. However, future studies are required to determine their side effects.

Published: June 2023

SARS-CoV-2 has been found to be the leading cause of the outbreak of coronavirus disease 2019 (COVID-19) globally. The disease is triggered by a new form of coronavirus and is characterized by acute respiratory distress syndrome (ARDS) or some primary chills. It was originated from a wet market in Wuhan, China and has engulfed 6.39 million lives globally uptillseptember-2022. Historically, the world has witnessed many noticeable epidemics in the form of, SARS-CoV (2002 to 2003), H1N1 influenza in 2009, and the most recent Middle East Respiratory Syndrome coronavirus (MERS-CoV), which erupted in Saudi Arabia in 2012. Different people get this disease with different symptoms including mild to severe illness. The molecular and cellular basis of SARS-CoV-2 pathogenesis gives us in-depth mechanisms involved. Experimental investigations have elaborated bats as the primary host for viral the transmission behind COVID-19. Moreover, the anatomy of the virus revealed its RNA based on the genome, which makes its therapeutic interventions more challenging. By the involvement of pre-analytic, analytic, and post-analytical strategies, patients with acute or chronic pneumonia can be distinguished as infected or not. Artificial intelligence has embarked significant importance in the course of viral detection based on computer algorithms. Furthermore, chemical or immune-based therapies were examined for finding a permanent solution to this epidemic issue. This review would cover every emerging aspect of pathogenesis, diagnosis, management, and the latest therapeutic interventions in the course of COVID-19 treatment. By giving rapidly evolving knowledge about this virus, readers are urged to update themselves regularly.
Not Quite Like Us? — Can Cyborgs and Intelligent Machines Be Natural Persons as a Matter of Law?
Authors: Gervais Daniel
Published: June 2023

The ability of AI machines to perform intellectual functions long associated with human higher mental faculties is unprecedented, for it is precisely those functions that have separated humans from all other species. AI machines can now imitate some of the outputs of our form of sapience; they can produce literary and artistic content and even express what seem like feelings and emotions. Calls for “robot rights” are getting louder. Using a transdisciplinary methodology, including philosophy of mind, moral philosophy, linguistics and neuroscience, this essay aims to situate the difference in law between human and machine in a way that a court of law could operationalize. This is not a purely theoretical exercise. Courts have already started to make that distinction and making it correctly will likely become gradually more important, as humans become more like machines (cyborgs, cobots) and machines more like humans (neural networks, robots with biological material). The essay draws a line that separates human and machine using the way in which humans think, a way that machines may mimic and possibly emulate but are unlikely ever to make their own.

Interdisciplinary approach in modern memory research
Authors:   L.N. Gumilyov Eurasian National University, Kudaibergenova A.A.
Published: June 2023

The study of memory in philosophy is associated with the search for answers to a wide range of questions that are detailed in different areas of scientific knowledge. In this regard, philosophers turn to the theoretical concepts of sociology, cultural studies, history, psychology, anthropology and other sciences. In Western philosophy, the study of memory has a long tradition based on the principle of rationality. Researchers have developed and continue to develop the terminological apparatus and tools necessary for the study of memory. Despite the accumulated experience of understanding memory, today there are many unresolved problems in Western philosophy, which the author proposes to study in this article within the framework of an interdisciplinary approach in the context of the perception of information disseminated by the media. This is very relevant in the context of globalization and the rapid development of information and communication technologies. The article substantiates that the study of memory in modern Western philosophy needs conceptualization, which is possible only within the framework of an interdisciplinary approach to the study of this phenomenon. The results of philosophers’ research should not be complex and often contradictory concepts, but complementary components of a single built-in system of knowledge about memory, in which there is a place for detailing memory research through the prism of different sciences. In the context of globalization, this will make it possible to exclude media manipulations aimed at replacing conceptual knowledge about memory for the sake of the opportunistic interests of political elites, as well as to take into account the existing advantages of the development of modern communication technologies that make it possible to spread the philosophical conceptualization of memory research in the society.
The Invisible Hurdle
Authors: Gray Nigel
Published: June 2023

International students pursuing higher education in the United States incur additional expenses compared to domestic students by spending on foreign credential evaluations and visa applications. These costs are usually not reflected in program fee structures, are non-refundable, and are not covered by financial aid, creating significant, and often unforeseen, financial strains on international students, particularly those from low-income backgrounds. This study compared the costs of two major foreign credential evaluators (Educational Credential Evaluators and World Education Services) and factored in the price of visa processing fees and the I-901 Student and Exchange Visitor Information System fee. It found that First-time, International, Graduate students pay up to $691 for foreign credential evaluations and visa applications. The paper suggests that higher education institutions should provide more transparent fee breakdowns and enhance financial aid packages to better support these students.

Los retos agrícolas para los países en desarrollo frente al proteccionismo de la Unión Europea: ¿La PAC como instrumento protector antidesarrollista? Caso: mercado del azúcar
Authors: Arreola Borja Laura Patricia
Published: June 2023

El sector agrícola ofrece el ejemplo más marcado de proteccionismo en la Unión Europea. La Política Agrícola Común (PAC) con frecuencia ha sido criticada por su carácter excesivamente proteccionista, la rigidez de sus mecanismos, altos impuestos arancelarios, etc. Esto ha generado descontento en varios países en desarrollo, tras los trastornos causados por esta política en los mercados mundiales. La OMC ha realizado varias reuniones, como la Ronda de Doha, para llegar a un acuerdo sobre la eliminación total de los subsidios de la PAC y se ha establecido como fecha límite el año 2013. Sin embargo, a pesar de que los subsidios se han reducido aún no se resuelven los desacuerdos entre países y las negociaciones se siguen aplazando. Los impactos que estos subsidios tienen sobre la agricultura de los países en desarrollo son negativos, especialmente en las exportaciones, que se ven reducidas debido a la baja de los precios de algunos productos clave para estos países, como es el caso del azúcar.
Evaluation of postoperative analgesic effect of auricular acupuncture therapy after surgical extraction of mandibular third molar
Authors: Bui Minh Man Pham , Trinh Dieu Thuong Thi
Published: June 2023

Removing the third molar is a common dental surgery that often results in swelling and discomfort, impacting the patient’s wellbeing. Previous studies have shown that auricular acupuncture (AA) can effectively alleviate pain after surgery. This study aimed to assess the pain-relieving benefits of AA for patients undergoing third molar surgery.

A clinical trial using a split-mouth design and double-blind methodology was conducted at the Dental Clinic of the University of Medicine and Pharmacy at Ho Chi Minh city between March 2022 and March 2023. Participants had both sides of their third molars extracted, with one side receiving AA in combination with postoperative pain relief medication, and the other side receiving sham AA along with postoperative pain relief medication. Pain levels at 2, 24, 48, and 72 hours after surgery, and the amount of pain medication used was recorded. Additionally, any side effects resulting from the AA treatment were also evaluated.

The pain levels measured by the Visual Analog Scale (VAS) decreased over time for both intervention periods after surgery, with statistically significant lower VAS scores observed in the AA time compared to the sham AA time. The amount of 500mg/tablet paracetamol used after the intervention also decreased over time for both periods. At all-time points, the amount of paracetamol used in the AA group was lower than the sham AA group. No adverse effects were reported in either group.

AA was effective for relieving pain after madibular third molar surgery and reducing amount of paracetamol tablets.
Reliability and validity of the Vietnamese menopause rating scale
Authors: Nguyen Hanh Thi My , Tran Nga Thi Tuyet , Nguyen Ha Minh , Do Dung Van
Published: June 2023

The menopause rating scale (MRS) has been proven to be a reliable tool for quantifying the impact of menopausal symptoms and aiding clinicians in prescribing appropriate treatments worldwide. However, the Vietnamese-MRS (VN-MRS) has not been developed. This research aimed to evaluate the reliability and validity of the VN-MRS, and identify factors that are associated with menopausal symptoms in women aged 50 to 59.

A cross-sectional study was conducted on a sample of 200 women aged 50 - 59 years in Vietnam from February 2020 to June 2020. The MRS was translated into Vietnamese following the procedure from the Berlin Center for Epidemiology and Health Research and adjusted to fit the local culture. Reliability was assessed by using Cronbach’s alpha coefficients and repeatability (using Intra-class Correlation Coefficient (ICC) at 2-week intervals). Validity was assessed by concurrent validity and construct validity.

Cronbach’s alpha for the total score was 0.89. Repeatability (test-retest) was valued as “very good” (ICC = 0.991). The fit indices for construct validity, after adjustment, were: χ2 (39) = 67.78 with p = 0.003; SRMR = 0.042; TLI = 0.971; CFI = 0.979; RMSEA = 0.061 90% confidence interval (CI) (0.035 – 0.084). Concurrent validity demonstrated an inverse correlation with the SF-36 survey (r = - 0.87; p<0.001). Age, education, and menopausal period were contributed to the menopausal score.

The VN-MRS has good reliability and validity, making it suitable for assessing the severity of menopausal symptoms in middle-aged Vietnamese women.
Study the effect of the tooth chamfer angle on the dog clutch shiftability
Authors: Aljawabrah Ayham , Lovas László
Published: June 2023

This paper studies the shiftability of the face dog clutch with chamfered teeth. The effect of the chamfer angle on the shiftability map and the probability are studied. In contrast to previous studies, a generalized mathematical model is developed based on the shiftability condition. The analysis considered two sets of cases: the overlap distance cases, and the chamfer side cases. The overlap distance cases locate the successful engagement position. The chamfer side cases investigate the effect of the system geometry and consider two cases. The results show that the chamfer angle has a negative effect on the dog clutch shiftability. Some geometric parameters show a different effect on the engagement probability for the rectangular tooth and chamfered tooth cases, and this behaviour is also analysed.

Published: June 2023

Kondisi pasca pandemi ini membuat siswa mempelajari setiap materi dari gadgetnya. Hal tersebut membuat pola pikir siswa sangat terbatas karena kepraktisan yang didapatkannya. Hanya dengan membuka satu situs internet, semua jawaban tentang materi yang dipelajarinya ada disitu. Hal tersebut membuat kemampuan penalaran matematis siswa tidak cukup berkembang. Oleh karena itu diperlukan adanya upaya dalam meningkatkan kemampuan penalaran matematis siswa yang salah satunya dengan memberikan pembelajaran yang sesuai dengan gaya belajar siswa. Dalam pembelajaran berdiferensiasi itu sendiri terdapat beberapa aspek kebutuhan siswa yang harus dipenuhi, yakni kesiapan, minat dan gaya belajar siswa. Pembelajaran berdiferensiasi mengedepankan konsep bahwa setiap siswa memiliki minat, potensi dan bakat tersendiri. Metode penelitian ini menggunakan metode kualitatif-deskriptif dengan tujuan mendeskripsikan kemampuan penalaran siswa dengan menggunakan pendekatan pembelajaran berdiferensiasi. Hasil dari tes tersebut menunjukan bahwa ketiga orang subjek ini memperoleh nilai yang cukup memuaskan setelah dilakukan pengelompokan berdasarkan gaya belajar. Nilai subjek yang pertama dengan gaya belajar visual meningkat dari 56 menjadi 82 , nilai subjek 2 dengan gaya belajar auditori meningkat dari 68 menjadi 80 dan nilai subjek 3 dengan gaya belajar kinestetik meningkat dari 65 menjadi 75. Dengan begitu kemampuan penalaran matematis siswa berkembang cukup baik dengan dilakukannya pendekatan pembelajaran berdiferensiasi.

Decisões judiciais sobre assédios e violências praticados contra trabalhadora mãe
Authors: Maeda Patricia , Severi Fabiana
Published: June 2023

O objetivo deste artigo é analisar a produção científica acerca de decisões judiciais em casos de assédio praticado contra trabalhadora atravessada pela maternidade. Como método, realizamos uma revisão de literatura nas principais bases de dados de conteúdo científico (BDTB Brasil, Portal de Busca Integrada da USP, DEDALUS, SCOPUS, Google Acadêmico, Redalyc, Scielo) sobre trabalhos datados de 2002 a 2022, indexados até 23/09/2022. Após a busca utilizando os descritores e a aplicação dos critérios de inclusão e exclusão, foram selecionadas sete pesquisas empíricas que analisaram decisões judiciais. Cinco estudos analisaram decisões judiciais sobre casos de assédio moral ou sexual no trabalho. Dois estudos avaliaram decisões judiciais em casos que envolviam a maternidade e as relações de trabalho. Para confirmar a pouca quantidade de trabalhos científicos que discutam assédios praticados contra trabalhadora mãe, foram agregadas três revisões bibliográficas que versaram sobre assédio moral no trabalho (AMT). Os achados indicam a necessidade de integrar as categorias gênero e maternidade às investigações científicas sobre decisões judiciais sobre assédio no trabalho, bem como a lacuna de investigações sobre o valor probatório do depoimento da vítima nos casos de assédio.

Abstract. Recently, the problem of low-alcohol consumption among adolescents and young people has become especially relevant, which was confirmed by the results of global WHO research and the ESPAD project in Ukraine (2019).

Aim. Study the age and gender characteristics of low-alcohol beverages among children and adolescents, identify risks and identify ways to minimize the negative impact of low-alcohol beverages on public health.

Materials and Methods. The data of the WHO and the ESPAD project, separate national researches on alcohol use by teenagers are studied; analyzed the results of the long-term epidemiological study "Family and Children of Ukraine", which is part of the WHO long-term European long-term study program on parenting and childhood "ELSPAC" (European Longitudinal Study of Parenthood and Childhood).

Results. According to the latest ESPAD study in Ukraine (2019), 85.7 % of all adolescents surveyed (more than 2,000 people) have consumed alcohol at least once in their lifetime, and the share of those who have consumed alcohol in their lifetime is ten and more times amounted to 46.3 %. According to the Family and Children of Ukraine study (989 people), the youngest age when alcohol was first consumed by adolescents of both sexes was 9 years of age and younger, with adolescent girls being more active than boys in their age. The analysis of the questionnaires ("Adolescent Questionnaires 15-18 years") revealed that among the surveyed adolescents, 67.4 % (725) people drank alcohol at least once in their lives, and there were more girls (69.5 % – 370 people) than boys (65.4 % – 355 people). The highest rates among adolescent boys were recorded in the 14-year-old group: 19.0 % drank beer for the first time, 14.5 % drank wine or champagne, 9.4% drank alcohol, and 7.4% drank strong alcohol. The highest rates of adolescent girls were found in the 15-year age group: beer was consumed for the first time by 16.9%, wine or champagne – 22.4%, alcoholic cocktail – 16.9 %, spirits – 8.6 %. Analysis of the degree of involvement of adolescents in beer consumption showed that at the age of 9 years and younger 3.9% (21) boys and 5.3 % (28) girls tried beer for the first time; at the age of 14 – 19.0 % (103) boys and 14.5 % (77) girls; at the age of 15 – 16.0 % (87) boys and 16.9 % (90) girls. Thus, the first time the interviewed teenagers tried beer was at the age of 14-15.

Conclusions. Consumption of low-alcohol beverages among children and adolescents in Ukraine is an acute social problem, the solution of which requires a systematic approach, which should include the formation and promotion of alcohol-free norms among young people, as well as marketing tools focus on priority consumption of soft drinks.

Published: June 2023

Objective. Based on the integrated indicator of the intensity of the innovation strategy and the integrated indicator of the intensity of the investment strategy the objective of the article is to determine the innovation and investment strategy for the development of tourism enterprises as hospitality industry subjects.

Methods. In the course of the research, the following methods are used: methods of theoretical generalization and comparison, analysis and synthesis (to determine the notion of the concept of “innovation and investment strategy”), index (to calculate the intensity of innovative and investment strategies using integrated indicators), matrix (to form a modi-fied GE / matrix McKinsey on the definition of innovative investment strategy of tourism enterprises).

Results. Based on the study, a procedure for the integration of innovative and investment strategies of tourism enterprises, which involves comparing a separate type of innovative strategy (traditional, opportunistic, imitative, defense, offensive) with a separate type of investment strategy (preservation, accumulation, moderate growth, aggressive growth) is proposed. Based on these data, innovative investment strategies for tourism enterprises using the modified GE / McKinsey matrix (investment plateau, innovation breakthrough, innovation pole, innovation circuit, innovation springboard, innovation pit, innovation plateau) are offered. Using the index method, the intensity of the innovation and investment strategy is calculated as integral indicators, which consist of individual indicators of innovation (growth index of financial potential, growth index of material and technical potential, growth index of staff potential, growth index of marketing potential, growth index of information potential) and investment (index of growth of own investments, index of growth of attracted investments, index of growth of profit on own investments, index of growth of profit on attracted investments, index of sufficiency of investments) potentials. To determine the innovation and investment strategy for the development of tourism enterprises, a rating scale is developed for assessing the integral indicator of the intensity of the innovation strategy and the integrated indicator of the intensity of the investment strategy. Accordingly, innovation-investment strategies for the development of the tourism enterprises under study are identified. The positions of tourism enterprises in the modified GE / McKinsey matrix on the definition of an innovative investment strategy for the development of tourism enterprises are presented.

Published: June 2023

Objective. The objective of the article is to investigate the methodological basis of application of forecasting models and methods in performing statistical assessment of economic risk, in particular, to assess the possibility of reducing systematic risk through forecasting planning of the enterprise and taking into account the semi-variance approach to risk calculation.

Methods. The theoretical basis of the study is achievements of foreign and national scientists. To achieve this goal, the following research methods are used: analysis, synthesis, abstract-logical and comparative analysis to classify economic risks and methods of their assessment; dispersion- semi-variance analysis to determine the level of risk indicators of the volume of sold industrial products by the type of economic activity; regression analysis to build forecast models, to obtain future values of sales indicators for industrial products by type of economic activity and to clarify the risk level for the evaluated indicators.

Results. The directions of risk classification and uncertainty are considered, the main approaches to the quantitative calculation of systematic economic risk are analyzed, semi-variance analysis and its advantages are determined. It is proposed to use the methods of moving averages and regression forecast modeling in determining the level of risk, which will more accurately take into account future values of uncertain indicators, and, consequently, will reduce the level of risk when planning the enterprise. In practice, the advantages of forecasting and semi-variance approaches to calculating the level of economic risk by indicators of the volume of sold industrial products by type of economic activity have been established.

Objective. The objective of the article is to investigate the territorial features of inbound tourism in Ukraine, analyze and develop measures that will be aimed at the development of the tourism industry in Ukraine.

Methods. The main scientific results of the work are obtained using a set of general scientific and special research methods, namely: methods of analysis, synthesis, generalization, systematization, abstraction and statistical analysis, comparative and graphical methods.

Results. The development of inbound tourism in Ukraine is influenced by the following factors: favourable natural conditions; rich historical and cultural heritage; availability of regulatory framework for tourism development; belonging to socio-geographical aspects. It is revealed that, according to the statistics of the State Border Guard Service of Ukraine, the largest number of foreign tourists was observed in 2014–2017 from such countries as Moldova, Belarus, Russia. Primarily, it was due to the territorial proximity of states, similarities of traditions, religions, lan- guages and related historical and cultural heritage.

According to the World Tourism Organization, the dynamics of international tourist arrivals in Ukraine is wave-like, the most observed international tourist arrivals were in 2017 (14.23 thousand people), the least — in 2015 (12.42 thousand people) and the growth rate of international tourist arrivals share in 2016 (7.33 %) and 2017 (6.75 %) and the least frequent in 2019 (-5.42 %). The main factors that contribute to such dynamics are the political situation in eastern Ukraine and the epidemic situation as in Ukraine and in the world.

It is noted that in order to improve the level of development of the tourism industry in Ukraine, it is necessary to carry out the following measures as attracting public funds for the implementation of tourism activities, improvement of transport infrastructure and amateurism, paying attention to health and recreational resources and attracting effective tourist advertising.

Published: June 2023

Objective. The objective of the article is to identify problems, opportunities and priorities for the development of green areas of Ukrainian cities.

Methods. The results of scientific research are obtained using a set of general and special research methods, namely: theoretical generalization (to study the essence of the definition of «green zone of the city»), factor analysis, systems analysis and synthesis (to determine the functions of green zones of cities and ways to measure economic value of green areas), statistical method (for processing and analysis of information on the structure of green areas of Ukraine, landscape-urbanization structure of green areas of cities and processing of statistical data on compliance with sanitary norms on green areas) abstract-logical method (in determining the main problems, opportunities and priorities for the development of urban green areas), abstract-theoretical method (for theoretical generalization and formation of conclusions).

Results. The study finds that the green zone of the city should be considered as a set of various greenery, which are a functional component of the spatial organization of the city and suburban area, and determines that the main functions of urban green areas are economic, environmental and social, which are implemented in such areas: economic development, protection and rehabilitation of the urban environment, recreation and tourism, architectural planning, protection and preservation of landscapes. According to the results of processing and analysis of statistical data on the structure of green areas of Ukraine and landscape-urbanization structure of green areas of cities, it is established that in the structure of green areas of Ukrainian cities the area is 45 %, limited use and special purpose are 30 % and 25 % respectively, the ratio of green areas of public use shows that the area of parks of culture and recreation, urban parks and squares is almost 41 %, embankments and boulevards — 20 %, water parks, meadows, forest parks — 13 % and other facilities — 33 %. Based on the analysis, it is determined that only 16.7 % of cities adhere to sanitary norms on the area of green plantations in cities, and 25 % of cities have an indicator lower than the average in Ukraine. According to the results of the study, the absence of a national policy for the development of green areas of the city is established and ways to form effective green and recreational spaces of Ukrainian cities are proposed.
