Published: April 2023

The FRONTIERS project worked with three Bolivian NGOs (Prosalud, the Center for Research, Education and Services or CIES, and the Association of Rural Health Programs or APSAR) to improve their ability to conduct research on market analysis and cost recovery. Following a one-week workshop on conducting cost studies, staff from the three NGOs designed operations research studies to help with decisions on planning and cost recovery. Study findings showed that cost recovery varied from high (Prosalud, 83-109%) to low (CIES, 38-46%) and very low (APSAR, 10-25%), depending on the service. All three studies focused on alternative options to client fees, including developing new services or market approaches (Prosalud), controlling costs (CIES), and continued donor support (APSAR).

Authors: Švab Katarina , Vilar Polona , Jug Tjaša
Published: April 2023

Intellectual property includes not only copyright but also industrial property (IP), which consists of inventions (patents), trademarks, industrial designs and models, and designations of origin. In order to identify the importance of these competencies of non-lawyers, e.g. engineers, managers, in companies, an online survey was conducted in some European countries as part of the Erasmus+ IPEDU project in 2021. This paper presents the results (n= 175) from four countries: Croatia, Portugal, Romania, and Slovenia. The results provide information about the perception of the importance of IP knowledge in industrial companies, the benefits of this knowledge for the companies, the implementation of training for employees, and the hiring practices of external experts. IP knowledge seems to be very important for companies, but they rarely organize IP training for their own employees. They require IP skills from job applicants and expect the education system to provide this knowledge. Important differences were found between countries, especially in the perceived usefulness of IP knowledge, skills, and training. As IP knowledge becomes increasingly important in industry and society, the study offers a new perspective on the importance of including IP in the education system and the need for non-lawyers to be knowledgeable in this area.
Research on online monitoring of grid current transformer based on transformers and BiGRU
Authors: Zang Xiaokui , Cao Zhiqiang , Xiao Mengshi , Yang Xiaoou
Published: April 2023

Transformers play a crucial role in ensuring the safety of power grids. It is of great value to diagnose faults using the large amount of power data generated by the grid. It is possible to detect internal latent faults in transformers in advance of their occurrence if the normal operating condition of the transformer is detected in a timely manner. To perform online fault diagnosis of grid current transformers, we combine the Transformer and BiGRU methods. There is a temporal component to the fault input sample sequences. By using Transformer’s multi-headed attention mechanism to extract deep features from fault input sample sequences, the temporal association between latent variables can be fully exploited. As a result of the extraction of features, BiGRU is used to generate fault category coding as an output. The experimental results indicate that using the proposed algorithm achieves better results than using a single model, which is useful for the study and application of fault diagnosis in power grids for current transformers.

An integrated CoCoSo-CRITIC-based decision-making framework for sustainable competitiveness evaluation of regional financial centers with interval-valued intuitionistic fuzzy information
Authors: Yang Biqin , Deng Yu
Published: April 2023

Due to the increasingly strengthened role of finance in modern economic development, theoretical research on regional financial competitiveness in the study of regional economic competitiveness becomes very important. For China at this stage, finance is in a period of rapid development, and its role has penetrated into all aspects of social and economic life. Especially after China’s entry into the WTO, the pace of opening up the financial market has been further accelerated, and comprehensive evaluation and analysis of financial competitiveness is of great significance for comprehensively understanding and accurately grasping China’s national conditions, national strength, and international competitiveness, promoting the long-term growth of China’s financial competitiveness, and the sustainable development of the financial industry. The competitiveness evaluation of regional financial centers is looked as the multiple attribute decision-making (MADM) problem. This paper intends to propose a MADM methodology based on CoCoSo (Combined Compromise Solution) method under interval-valued intuitionistic fuzzy sets (IVIFSs) for sustainable competitiveness evaluation of regional financial centers. At the end of this study, we noticed to a comparison between the proposed IVIF-CoCoSo approach with other existing methods to verify the effectiveness of the algorithm.
The implicit mathematical reasoning model combining self-attention and convolution
Authors: Yao Zhuangkai , Zeng Bi , Hu Huiting , Wei Pengfei
Published: April 2023

In recent mathematical reasoning tasks, self-attention has achieved better results in public datasets. However, self-attention performs poorly on more complex mathematical problems due to the lack of capacity to capture local features and the ill-conditioned training after deepening the number of layers. To tackle the problem and enhance its ability of extracting local features while learning the global contexts, we propose an implicit mathematical reasoning model that improves Transformer by combining self-attention and convolution to achieve joint modeling of global and local context. Also, by introducing Reweight connection and adversarial loss function, we prevent the model gradient from disappearing or exploding in a deep neural network while ensuring the convergence speed and avoiding overfitting. Experimental results show that the proposed model improves the accuracy by 4.47% on average for complex mathematical problems compared to the best existing results. In addition, we verify the validity of our model using ablation analysis and further demonstrate the interpretability of the model by attention mapping and task role analysis.

Published: April 2023

Underwater wireless sensor networks (UWSNs) are designed to perform cooperative monitoring and data collection tasks by combining several elements, such as automobiles and sensors located in a particular acoustic area. Several studies have been carried out to improve energy efficiency and routing reliability. However, UWSN faces several challenges, such as high ocean interference and noise, long transmission delays, limited bandwidth, and low sensor node battery energy. In this work, a novel underwater clustering-based hybrid routing protocol (UC-HRP) has been proposed to address these issues. The overall process is carried out in three phases. In the first phase, the fuzzy-ELM approach is used to initialize the cluster based on parameters such as Doppler spread, path loss, noise, and multipath. In the second phase, the cluster head is selected using Cluster Centre Cluster Head Selection (C3HS) based on Link quality, distance, node degree, and residual energy. In the third phase, Hybrid Artificial Bee Colony (HABC) algorithm is used for selecting an optimal route based on the parameters such as reliability, bandwidth effectiveness, average path loss, and average transmission latency. The performance of the proposed UC-HRP method is evaluated using a variety of parameters, including the network lifetime, packet delivery ratio, alive nodes, and energy consumption. The proposed technique improves the network lifetime by 14.03%, 16.25%, and 18.34% better than ACUN, ANC-UWSNS, and MERP respectively.

Authors: Bennett E. , Fletcher A. , Talbot E. , Robinson L.
Published: April 2023

BACKGROUND: Returning to education (RtE) after an acquired brain injury (ABI) can be stressful for children/young people (CYP) and families. While much can be done to support RtE, there has been limited exploration of the lived experience of parents/carers about what can both help and hinder the process. OBJECTIVE: The aim was to understand more about RtE from parents’ perspectives to inform best practice and facilitate improvements in service delivery. METHODS: A service evaluation explored parent/carer views about the RtE process and the support received from healthcare professionals at a regional centre in the UK. Questionnaires (n = 59) were sent to parents of patients treated for an ABI in the last two years. RESULTS: 31 parents (response rate = 51%) completed the survey. Results highlight the many challenges of RtE. Thematic analysis of responses revealed six key themes: Parental mindset and growth; What do they need now?; Specialist support and information; Talk and share; Challenges of new and hidden needs; and Don’t forget them! CONCLUSION: Parents offer crucial insight into the challenges of the RtE process. Their feedback highlights important factors for service development and reminds professionals of the key components of an effective return.

Published: April 2023

BACKGROUND: Return-to-school processes indicate ‘when’ to initiate activities and ‘what’ activities should be accomplished, but are missing ‘how’ to implement the process. The SCHOOLFirst website provides the ‘how’ through building concussion knowledge, creating a supportive culture, and defining roles. Due to the involvement of pre-service teachers in schools during training and imminent transition to becoming teachers, it is important that pre-service teachers are trained in concussion and can optimally support current and future students. OBJECTIVE: To determine: 1) pre-service teachers’ knowledge and confidence surrounding the return-to-school process before and after using the SCHOOLFirst website; 2) the usability, intended use and satisfaction of the SCHOOLFirst website from the perspective of pre-service teachers. METHODS: Thirty pre-service teachers completed the demographic survey, knowledge and confidence survey, System Usability Scale, and satisfaction and intended use survey after participating in a workshop. RESULTS: Significant increases in concussion knowledge (Z = –4.093, p < 0.001) and confidence in helping students return-to-school (Z = –4.620, p < 0.001) were measured after using the SCHOOLFirst website. Participants were satisfied with the SCHOOLFirst website (93.4%) and intend to use it in the future when supporting a student post-concussion (96.4%). CONCLUSION: The SCHOOLFirst website is a valuable tool for pre-service teachers to support students’ return-to-school post-concussion.

Published: April 2023

BACKGROUND: According to the eighth edition of the tumor node metastasis (TNM) staging system for esophageal cancer, it is recommended that extracapsular lymph node involvement (EC-LNI) is included as a registered independent variable for the disease. However, its role in the prognosis has not been clearly explained. OBJECTIVE: To study the value of EC-LNI in the prognosis of esophageal cancer and attempt to explore its molecular mechanism via an enrichment analysis. METHODS: A retrospective analysis was performed on 544 patients with esophageal squamous cell carcinoma (ESCC) who underwent radical surgery in the department of thoracic surgery of our hospital, focusing on the relationship between EC-LNI and clinicopathological characteristics and its effect on prognosis. Additionally, the mechanism of EC-LNI in esophageal cancer was explored. RESULTS: Among the 271 patients with lymph node metastasis, 125 were EC-LNI (+). The degrees of tumor differentiation, location, TNM stage, vascular tumor thrombus, and nerve invasion were related to the occurrence of EC-LNI. The stage of TNM was considered an independent risk factor for the development of EC-LNI. A significant difference was found in terms of overall survival (OS) and disease-free survival (DFS) between the EC-LNI (+) and EC-LNI (-) groups. A univariate analysis showed that the degrees of tumor differentiation, T stage, N stage, TNM stage, EC-LNI, EC-LNI number, and EC-LNI distance were significantly correlated with prognosis. A multivariate survival analysis showed that tumor differentiation, TNM stage, and EC-LNI were independent prognostic factors for OS, while TNM stage and EC-LNI were independent prognostic factors for DFS. The enrichment analysis identified the molecular targets and signaling pathways that can regulate cell proliferation, differentiation, and apoptosis. CONCLUSION: Extracapsular LNI has a high prognostic value in patients with esophageal cancer and is closely related to the stage of tumors. Our preliminary molecular mechanism research indicated that the molecular targets of EC-LNI are expected to become a new direction for the treatment of esophageal cancer.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease worsening airflow limitation. OBJECTIVE: To explore pulmonary function rehabilitation, life quality and prognosis in patients with severe COPD. METHODS: Between February 2018 and August 2021, 150 patients with severe COPD cured in our hospital were arbitrarily assigned into the control group (n= 75) and study group (n= 75). The control group received routine treatment and the research group received multidisciplinary diagnosis and treatment. The body mass index, airflow obstruction, dyspnea and exercise (BODE), pulmonary function, the number of acute attacks, 6-minute walking distance (6MWD), Borg score and life quality were compared. RESULTS: There was no remarkable difference in BODE score before treatment (P> 0.05). During the 2- and 6-month following treatment, the BODE score of the study group was lower (P< 0.05). In the study group, FEV1 percentage of the predicted value, forced expiratory volume in one second (PPO-FEV1) and the percentage of forced expiratory volume in one second/forced vital capacity (FEV1/FVC) in the first second were higher (P< 0.05). In the study group, there were fewer acute attacks (P< 0.05). After treatment, the 6MWD of the study group following 2- and 6-month treatment was higher (P< 0.05). The Borg scores of the study group at 2- and 6-months after treatment were lower (P< 0.05). There were no remarkable differences in the score of life quality before treatment (P> 0.05), however, the symptom score, activity score, influence score and total score of the study group were lower after the treatment (P< 0.05). CONCLUSION: The application of multidisciplinary diagnosis and treatment model can promote the rehabilitation of pulmonary function of patients with severe COPD, improve their prognosis, slow down the development of the disease and enhance their life quality.

Published: April 2023

BACKGROUND: Many studies have evaluated physical activity and fatigue. However, a causal relationship between physical activity, fatigue and balance in healthcare workers has not been established. OBJECTIVE: To evaluate the activity levels, fatigue, and dynamic balance of health workers who work actively or in a desk job in many different units in the hospital. METHODS: 72 Health workers from two different groups participated in the study, 37 were active workers (AW), and 35 were desk workers (DW) at the Diyarbakir Gazi Yaşargil Training and Research Hospital. Participants were given a Sociodemographic Information Form, an International Physical Activity Questionnaire (IPAQ), and a 30-s Chair Stand Test (30-s CST) with a Modified Borg Scale (MBS) before starting work in the morning and at the end of work. RESULTS: 69.4% of the study participants were female, and 54.2% were between 20 and 30 years old. It was found that the values of moderate physical activity, walking, and total physical activity were significantly higher in active workers than desk workers (p = 0.000). There was no statistically significant difference between the means of work start and after work fatigue of both groups (p > 0.05). A statistically significant difference was found when the starting and finishing work values of the dynamic balance tests of the groups were compared (p = 0.006). CONCLUSION: It was found that the level of physical activity and dynamic balance of individuals working at desk jobs was significantly lower than that of the active group.

The main basic researches of Ukrainian scientists are considered, which make it possible to affirm the independence of the school, the sufficiency of scientific and project developments, forms of complex solutions to issues related to the settlement-territorial community-district-region-country system, and most importantly, the super-powerful human professional potential of specialists in various industries that have always been interested in the problems of urban development. An attempt was made to prove that Regional Planning is one of the tools for building the country's development strategy at all levels.

In the district triad - planning-town planning-architecture, the central city is occupied by town planning. In the work, the triad is considered from the position of a single continuous process for solving specific objects, where urban planning is only an intermediary between district planning and architectural design, ensuring a gradual process of transition of solving problems from the regional level to a specific object.

The work considered and proposed to consider the periodization of regional planning from the perspective of a paradigm or prediction of a set of problems that are most relevant in one or another period of the country's development, which makes it possible to more reliably solve the tasks of the urban planning sphere thanks to the scientific concentration of research at all levels at the same time.

In addition, regional planning is considered from the position of a powerful tool for finding solutions for organizing the country's settlement system at all levels.
STAGES OF STYLISH DEVELOPMENT OF THE ARCHITECTURE OF ELIZABETHGRAD AT THE SECOND HALF OF THE 19TH – BEGINNING OF THE 20TH CENTURY
Authors: Penyaz Tatyana
Published: April 2023

The article is devoted to the architecture of Yelysavetgrad at the second half of the 19th century and the beginning of the 20th century, that forms a large part of the historical center of the city and contains information about the development of medium-sized cities in southern Ukraine. The article presentes a classification of stylistic features and stages of the development of the Yelisavetgrad architecture of the period under study. On the basis of field surveys, studses of literary and archival sources, patterns of stylistic development, depending on the preferences of the time and the functional purpose of the buildings were revealed.

In the development of Yelisavetgrad architecture of the studied period, four stages are distinguished: two stages of the development of eclecticism and two stages of the development of modernism. The first stage is characterized by a close connection with the classical heritage of the previous period and the influence of romanticism. It was called retrospective, because historical prototypes were used in the creative search for new forms. At the second stage, eclectic combinations of forms and decor were developing.

The third stage is the most innovative. It is characterized by the development of international trends of modernism (decorative and rational) in combination with forms and directions of eclecticism. A combination of modern and ancient is observed in modern architecture. At the final stage, neoclassicism is more pronounced and complete than in previous periods. The article analyzes the connections between stylistic directions at each stage and their genesis during the studied period.

Stages in the architecture of the studied period differ in the quality of changes in the stylistic development of the research objects. The results of the study represent the classification of objects according to the period of construction, of the stylistic direction and typology. This work can be used in further studies of the features of the architectural and planning development of Yelisavetgrad architecture in the second half of the 19th and the beginning of 20th centuries.
IMPROVING THE EFFICIENCY OF CURRENT ASSET MANAGEMENT ASSETS AND SHORT-TERM LIABILITIES OF URBAN DEVELOPMENT ENTERPRISES
Authors: Chovniuk Yurii , Cherednichenko Petro , Ostapushchenko Olga , Mischenko Olena
Published: April 2023

The article proposes an approach that takes into account inflationary factors in the tactics of financial management, namely in the processes of managing current as-sets and short-term liabilities of enterprises involved in urban development (a rein-forced concrete plant, a house-building enterprise, etc.). The most important point here is the choice of the level of the interest rate at which discounting is performed. This value is commonly referred to as the comparison rate. An important point in deter-mining the interest rate used for discounting is the consideration of risks. Since the risk in the analysis of production investments, regardless of its specific forms, ultimately appears in the form of a possible decrease in the real return on capital compared to the expected one, and this decrease again manifests itself in time, therefore, as a general recommendation for taking into account possible losses from reduction in returns, in-flationary depreciation of money, etc. it is usually proposed to introduce an amendment to the level of interest rate characterizing the yield on risk-free investments (for ex-ample, in short-term government securities), i.e. to add a certain risk premium that takes into account both the specific risk associated with the uncertainty of receiving income from a specific investment of an enterprise involved in urban development (a reinforced concrete plant, a house-building plant, etc.) and the market risk associated with the situation. This approach is particularly relevant in Ukraine today, with the ongoing war with Russia. The study presents the basic principles of tactical financial management of Ukrainian urban development enterprises in the context of high infla-tion, which relate to the following 1) volumes and speed of turnover; 2) net debtor position; 3) dynamics of enterprise prices and the method of calculating weighted av-erage prices; 4) changes in consumer costs when prices for raw materials, energy, equipment, etc.; 5) the policy of using of free cash of the enterprise in case of infla-tionary depreciation.

The article is devoted to the creation of a fundamentally new scientific and methodological basis for the adaptation of construction project stakeholder enterprises to dynamic shifts in the construction market through the implementation of an adaptive strategy of renewal and change management in the form of a target project of transformations of the management system of a construction enterprise. The urgency of revising the content of processes and approaches to the organization of economic and managerial interaction of the executing enterprise with institutional participants in the construction and investment process has been worked out. The content of the basic definitions of the study, first of all, the definition of "transformation of the operating system", from the standpoint of analysis and adjustment of the development strategy of the construction enterprise, taking into account the operational and production features of the functioning of the developer as an executor of construction projects, is summarized. The specifics of the market of construction development projects have been highlighted through the prism of prerequisites and the environment of transformational changes in the functioning of stakeholder enterprises. The expediency of using maps of logical-cognitive characteristics as a component of the toolkit, which provides the possibility of combining the means of management strategies of the construction enterprise for the construction engineering enterprise, is substantiated. The theoretical-methodological, analytical and scientific-applied developments are integrated into the complex of applied modules of the formalized economic and management justification of the project of strategic innovative transformations at the construction enterprise. Procedures for identifying the potential of transformations at the enterprise, developed within the methodological approach, evaluate the internal and external potential of transformations at the enterprise, which makes it possible to determine those of them that should use a proactive approach to transformations and the selection of projects for their implementation.
RESEARCHES OF CHANGES OF THE COEFFICIENT OF A FILTRATION OF THE POROUS MEDIA AT THE DIFFERENT TYPES OF FORMATION OF A DEPOSIT. THE THEORETICAL ANALISIS AND PRACTICAL RECOMMENDATIONS FOR CALCULATIONS OF CLEARING FILTERS
Authors: Obertas Irina
Published: April 2023

On the basis of analogy betweem the laminar flow of a viscous liquid in a tube and a filtration in the porous media which submits to the linear law of resistance Dar-cy the formula for calculation of coefficient of a filtration at the combined form of adjournment of a deposit is obtained. Practical recommendations for a choiсе of theoretical and approximating experimental dependences for different types of formation of a deposit are given.

Theoretical and applied studies of filtration of heterogeneous ridins in porous mediums with changing powers took away significant development in connection with solutions to the problems of water purification in the form of finely dispersed mineral and columnar particles and speeches. Changes in the power of porous media are observed in the history of various mechanical, physical-chemical and biological processes of mass transfer which are visible on the surface of the particles of the middle (surfase – the slurry type of the settlements of the siege after adsorption), or without the middle in the port channels (volume – the dispersed type of the settlement of the siege).

With accumulated siege (the process of colmatation), a change in porosity and filtration coefficient is observed, and with inflows (the process of suffocation) – an increase in these important parameters of the porous medium.

When filtering rich-phase and rich components sieges, it can be settled in a mixed (complex) form, like in plivkovy so in general. In case of filfiltration of rich-phase and rich-component native sediments, it can be settled in mixed (complex) forms – like in smelt, and in general forms. The type of the process of the siege of creation and indicated on the basis of laboratory data. To lie in the nursery area on the surface of the particles of interest, adhesive and sorption power of the particles of the medium, according to the type of encroachment, district, temperature and other char-acteristics of the porous medium and pore waters.
NP on Logarithmic Space
Authors: Vega Frank
Published: April 2023

P versus NP is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is P equal to NP? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency. However, a precise statement of the P versus NP problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. Another major complexity classes are L and NL. Whether L = NL is another fundamental question that it is as important as it is unresolved. The problem HORN2UNSAT consists of deciding whether a Boolean formula with Horn clauses of at most two literals is not satisfiable. We prove if HORN2UNSAT is in L, then L = NL. Besides, we show that every NP problem is in L with oracle access to L under the assumption that HORN2UNSAT is in L. We might not be able to confirm whether the problem UNSAT is in P, but we do know that HORNUNSAT is indeed in P. Something similar could happen between 2UNSAT and HORN2UNSAT regarding the properties of the class L. We claim that the problem HORN2UNSAT could be in L and thus, we obtain that P = NP.

Riemann Hypothesis on Grönwall's Function
Authors: Vega Frank
Published: April 2023

Grönwall's function \(G\) is defined for all natural numbers \(n > 1\) by \(G(n)=\frac{\sigma(n)}{n \cdot \log \log n}\) where \(\sigma(n)\) is the sum of the divisors of \(n\) and \(\log\) is the natural logarithm. We require the properties of extremely abundant numbers, that is to say left to right maxima of \(n \mapsto G(n)\). We also use the colossally abundant and hyper abundant numbers. A number \(n\) is said to be colossally abundant if, for some \(\epsilon > 0\), \(\frac{\sigma(n)}{n^{1 + \epsilon}} \geq \frac{\sigma(m)}{m^{1 + \epsilon}}\) for all \(m > 1\). Let us call hyper abundant an integer \(n\) for which there exists \(u > 0\) such that \(\frac{\sigma(n)}{n \cdot (\log n)^{u}} \geq \frac{\sigma(m)}{m \cdot (\log m)^{u}}\) for all \(m > 1\). The Riemann hypothesis is a conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part \(\frac{1}{2}\). It is considered by many to be the most important unsolved problem in pure mathematics. There are several statements equivalent to the famous Riemann hypothesis. We state that the Riemann hypothesis is true if and only if there exist infinitely many consecutive colossally abundant numbers \(3 \leq N < N'\) such that \(G(N) \leq G(N')\). In addition, we prove that the Riemann hypothesis is true when there exist infinitely many hyper abundant numbers \(n\) with any parameter \(u \gtrapprox 1\). We claim that there could be infinitely many hyper abundant numbers with any parameter \(u \gtrapprox 1\) and thus, the Riemann hypothesis would be true.

ВИКОРИСТАННЯ БАГАТОРІЧНИХ ЗЛАКОВИХ КУЛЬТУР В ОЗЕЛЕНЕННІ МІСТА ХЕРСОН
Authors: БОЙКО Т.О. , КОТОВСЬКА Ю.С.
Published: April 2023

Метою нашої роботи було дослідити еколого-біологічні властивості декоративних злакових культур що використовуються в озелененні Херсону, виявити та відібрати стійкі в умовах Південного Степу види та сорти для широкого впровадження в різні об’єкти озеленення міста. Матеріали та методика дослідження. Досліджено ритм сезонного розвитку рослин методом фенологічних спостережень. Встановили зимостійкість та посухостійкість всіх досліджених видів. Встановлено морфометричні показники видів та сортів досліджених злакових. Декоративність рослин оцінювали за сукупністю ознак вегетативних та генеративних органів. Результати дослідження. Злаки, обрані для озеленення Херсону, декоративні переважно формою та забарвленням листя. За забарвленням листя ми розділили їх на кілька груп: з зеленим, зі строкатим, з сіро-голубим забарвленням. Ще однією декоративною ознакою злаків є форма та забарвлення генеративних органів. В озелененні Херсону використовують рослини з крупними суцвіттями, так і рослини з малодекоративними непоказними суцвіттями. Застосування злакових рослин у ландшафтному дизайні залежить від висоти їх пагонів. Нами виділено низькорослі – до 0,6 м, середньорослі – 0,6–1,5 м, високорослі рослини – понад 1,5 м. Початок росту злаків в умовах Херсону починається навесні. Найбільш ранньовесняним видом є Festuca glauca Vill. ‘Elijah Blue’, Phalaris arundinacea L. ‘Picta’, Panicum virgatum L., Bouteloua gracilis (Willd. ex Kunth) Lag. ex Gr тощо. Розвиток інших рослин починається на місяць-півтора пізніше. Phyllostachys nigra (Lodd. ex Munro) залишається вічнозеленою рослиною в досліджених умовах. Висновки. Всі досліджені злакові пройшли інтродукційні випробування, відрізняються високою зимостійкістю та посухостійкістю. Вони можуть бути рекомендовані до широкого використання в ландшафтному дизайні об’єктів різного цільового призначення в умовах міста Херсон та Херсонській області.
