Ethnocultural Specificity of Phraseological Units with Zoocomponent in German and Ukrainian Languages
Authors:   Beketov Kharkiv National University of Municipal Engineering, Ostapchenko V
Published: December 2021

Abstract. The article presents a comparative analysis of phraseology with zoonymic components in the German and Ukrainian worldviews, which are closely related to national culture. In most phraseologies with the component-zoonym there is a type of metaphorical transfer, which uses the names of animals to describe the characteristics of man, the designation of certain qualities, appearance, character, mental abilities. In addition, zoonyms are often symbols of moral and intellectual qualities of man. The purpose of research is to study phraseological systems with zoomorphic components in a pair of German - Ukrainian, which allows to identify important values of each nation. Results of research. During the study of zoonyms in phraseology, it was noted that the metaphorical nature of zoomorphic phraseology, their inherent subjective-evaluative connotation, the specificity of their semantic parameters and syntactic structure is largely due to their scope, based on their expressed anthropocentrism as a manifestation of traditions of attributing to animals certain traits of human character. In the ethnoculture of different peoples, phraseology, including the names of animals - is primarily a statement about man, his spiritual and social traits. Thus, phraseology with the names of animals can reflect: physical qualities, capabilities; appearance; mental qualities (character traits); intelligence; habits, abilities, skills. Also, the paper explores the common and distinctive features of phraseology of the Ukrainian and German languages, namely the zoocomponents that form complete equivalents. Such phraseological units are equivalent, ie their lexical volume, semantic meaning and meaning are symmetrical. The second group includes partial equivalents. In German and Ukrainian, such phraseological units have the same meaning, but differ in the composition of lexical components, and, consequently, the internal form. The third group includes phraseologies that have no equivalents in another language and are characterized by the fact that these concepts do not have a common object. Such phraseological units often remain outside the scope of bilingual phraseological dictionaries, which is why it is only possible to explain the meaning. Originality is determined by the fact that our study makes a contribution to the development of phraseology in terms of studying phraseological units, namely the animalism of the German and Ukrainian languages. Conclusion. The presence of common and distinctive features in the structures of phraseology of the studied languages, the nature and content of associations are determined not by the properties of animals, but by their life in the national folklore-mythological and literary contexts of each nation, its worldview, human existence.

EUROPEAN INTEGRATION: ADVANTAGES AND THREATS TO UKRAINE’S FOREIGN TRADE
Authors: Tetiana ZUBKO
Published: December 2021

Background. In terms of unfavorable external conditions and a significant deterioration of the socio-economic situation, the Ukrainian market has stagnated. Russia’s actions, including its unilateral suspension of the Free Trade Agreement, have led to a reduction in Ukraine's bilateral foreign trade operations. The processes of globalization and integration issue new challenges to the economy of any country, in particular, the questions of evaluation and stimulation of foreign trade of enterprises emerge in the conditions of constant transformation. Therefore, the aim of this study is to identifytrends and features of Ukraine’s foreign trade in the context of globalization and integration. Materials and methods. The article is based on a synthesis of research results of domestic and foreign scientists to determine the main influencing factors of cooperation with the EU on the state of development of Ukraine’s foreign trade. Research on this issue was conducted using the methods of theoretical generalization, analysis and synthesis. Results. Ukraine’s position in world trade is determined by the main factors: the dynamics of GDP, rating and index of economic freedom. The peculiarities of Ukraine's foreign trade over the last decade have been studied, the main partner countries; the main challenges that arise in our foreign trade as a result of European integration processes have been identified. It is proved that in the analysis of GDP it is expedient to use the indicator of GDP calculated on purchasing power parity. It is established that in the conditions of the world crisis, the war in the east caused the greatest damage to the economy of Ukraine. It was clarified that Ukraine needs to expand the geography of foreign trade relations, at the same time there is a significant unrealized potential for the development of bilateral relations with EU countries. Conclusion. Ukraine must follow the chosen course of European integration, but at the same must also develop other partnerships with countries on other continents. Unfortunately, Ukraine exports more raw materials and goods with low added value. Therefore, there is a need: to change the content of exports, to introduce tax and customs instruments to support exports, to amend the Association Agreement in terms of international trade. The structure of foreign trade does not stimulate Ukraine's economy to innovative development, so there is an urgent need for domestic policy reforms and changes in external priorities.

Published: December 2021

Many studies on art education outline the positive effects of arts education on individuals' cognitive, social and emotional development, however, it can be seen that three-dimensional studies cannot be conducted adequately due to various reasons such as insufficient workshop facilities, short course durations, and difficulties in accessing materials in visual arts courses in state schools in Turkey. It is possible to say that arts education will be incomplete in many aspects when including three-dimensional art works are not included in the educational practices. From this point of view, this study aimed to interpret the opinions of pre-service visual arts teachers regarding their views on three-dimensional art works within the scope of the elective art workshop sculpture course. The ‘case study’ design, as a qualitative research method, was emplyed in the study. The study group consisted of 24 pre-service visual arts teachers studying Visual Arts and Crafts Education Bachelor of Arts program at 4th grade at a state university in Western Black Sea Region in Turkey. The research data were obtained through semi-structured interview forms and analyzed by content analysis method. The results of the study showed that pre-service visual arts teachers found the "plaster figure sculpting" and "aerated concrete portrait block" art works made within the scope of the elective art workshop sculpture course useful in perceiving three-dimensional forms and understanding human anatomy. Moreover, they stated that they may prefer such works in their professional lives because it is convenient in terms of material cost and accessibility.

This article analyzes the expression of individual limitation in Nekrasov’s poetry as a model of democratic pathos which departs from the 1860s standard of self-sacrifi ce. Who Lives Well in Russia is treated as a culminating expression of Nekrasov’s unique combination of individual lyric voice and the shared affective experiences created by sound, which symbolizes a bid for agency among the intelligentsia and the narod alike and draws attention to linguistic form as a combined poetic and political act.
On a Little-Known Slavic-Moldavian Copy of the Old Russian “Parables of Wives”
Authors:   Russian State Library, Paskal Aleksandr D.
Published: December 2021

The article presents a textual analysis and a publication of a little-known copy of the anonymous Old Russian text “Parables of Wives” (“Pritchi o zhenakh”), found in a handwritten Slavic Horologion with additional articles in the Russian State Library (Fond 209, No. 201). The manuscript is of Moldavian origin and dates back to the first quarter of the 16th century. It is established that literary sources of the entries that constitute the “Parables of Wives” are mainly didactic statements from the florilegia The Bee (Pchela, Melissa) and Menander. The discovered text is a special compiled redaction of the “Parables”. The author did not simply select individual entries from those florilegia but also changed the order in which the aphorisms appear compared to their position in The Bee and Menander. At the same time, he partly edited their content. Most likely, the Moldavian copyist had a corrupted copy of the “Parables of Wives” in front of him, which he could not copy correctly, thus preserving its erroneous readings in his copy
Development of blocking compositions with a bridging agent for oil well killing in conditions of abnormally low formation pressure and carbonate reservoir rocks
Authors: Mardashov Dmitrii
Published: December 2021

Production well killing before workover operations in late-stage oil and gas-condensate fields can be complicated by abnormally low formation pressure, carbonate type of reservoir rocks, and high gas-oil ratio. These complications lead to the intensive absorption of technological fluids by the formation and gas ingresses, which, in its turn, increases the time of killing wells and putting them on production, reduction of productivity, and additional costs. Therefore, it is crucial to develop a high-performance well-killing composition that would allow improving the efficiency of killing wells in complicated geological, physical, and technological conditions at the expense of  reliable overlapping  of the perforation interval (or open wellbore) to prevent gas intakes and gas outflow from the formation. To develop blocking compounds, a set of laboratory tests has been carried out, including physical and chemical (determination of density, viscosity, thermal stability, sedimentation stability, etc.) and research of blocking and filtration properties of compositions during simulation of a fractured reservoir. In the course of laboratory tests, the choice of fractional composition and polymer filler concentration was substantiated in the blocking emulsion and polymer compositions to increase the efficiency of their application under the complicated conditions of killing oil wells.  As a result of laboratory research and field tests, the emulsion and polymer blocking compositions containing bridging agent (microcalcite) were developed, which increase the oil well killing efficiency by preventing the absorption of technological fluids in the formations and, as a result, preserving its productivity.

Authors: Abed Hadeel S. , N. Abdullah Hikmat
Published: December 2021

Cognitive radio (CR) is a promising technology for solving spectrum sacristy problem. Spectrum sensing  is the main step of CR.  Sensing the wideband spectrum produces more challenges. Compressive sensing (CS) is a technology used as spectrum sening  in CR to solve these challenges. CS consists of three stages: sparse representation, encoding and decoding. In encoding stage sensing matrix are required, and it plays an important role for performance of CS. The design of efficient sensing matrix requires achieving low mutual coherence . In decoding stage the recovery algorithm is applied to reconstruct a sparse signal. İn this paper a new chaotic matrix is proposed based on Chebyshev map and modified gram Schmidt (MGS). The CS based proposed matrix is applied for sensing  real TV signal as a PU. The proposed system is tested under two types of recovery algorithms. The performance of CS based proposed matrix is measured using recovery error (Re), mean square error (MSE), and probability of detection (Pd) and evaluated by comparing it with Gaussian, Bernoulli and chaotic matrix in the literature. The simulation results show that the proposed system has low Re and high Pd under low SNR values and has low MSE with high compression.
Analysis of the bond-slip performance of steel bars and steel fiber recycled concrete based on the constitutive relationship model
Authors: Xia Zhengbing , Duan Xiaofang
Published: December 2021

In order to promote the application of steel fiber recycled concrete in projects such as roads and bridges, 25 groups of steel fiber recycled concrete with different mix proportions were designed, taking the replacement rate of recycled aggregate and the volume fraction of steel fibers as experimental parameters, and 77 steel bars and steel fiber recycled concrete bonded specimens were made and pasted with strain gauges for the pull-out test. The research results showed that the greater the replacement rate of recycled aggregates was, the lower the bond strength between steel bars and steel fiber recycled concrete was; in the range of 0~1.2%, the higher the mixing amount of steel fibers was, the greater the bond strength of the specimen was; in the range of 0~1.6%, the higher the mixing amount of steel fibers was, the greater the slip value of the specimen under the peak load was; the addition of steel fibers improved the failure behavior of the recycled concrete pull-out specimens; the test specimens mainly had pull-out failure when the mixing amount of steel fibers was 1.2% and 1.6%. Finally, this study modified the bond-slip constitutive relationship model of steel and steel fiber recycled concrete, analyzed the influence of the replacement rate of recycled aggregate and the mix proportion of steel fibers on its bonding performance, and compared the results with the test results. The results demonstrate that the test curve is in good agreement with the fitted curve, which can provide theoretical support for engineering applications.

Published: December 2021

In this research, the finite element method is used to develop a numerical model to analyse the effect of the external strengthening of reinforced concrete beams by using carbon Fiber Reinforced Polymer (CFRP) sheets. A finite element model has been developed to investigate the behavior of RC beams strengthened with CFRP sheets by testing nineteen externally simple R.C. beams, tested under a four-point load setup until failure. Various CFRP systems were used to strengthen the specimens.  The numerical results using the (ANSYS workbench v.19.1) were calibrated and validated with the experimental results.  The research results indicate a significant improvement in the structural behavior of the specimens strengthened using CFRP sheet systems. Then the validated model investigated the effect of the width of CFRP sheets, no of layers, and CFRP size on the behavior of strengthened R.C. beams. Results of this numerical investigation show the effectiveness of increase CFRP width to improve the flexural capacity of R.C. beams. An increase in the flexural capacity up to 100 % compared to the control beam.

Published: December 2021

Given the field of application and the many advantages, the use of FGM (Functionally Graded Materials) materials has recently been extended in several components and more particularly in cylindrical structures, which have been the subject of several recent studies. Our work aims to use the finite element method to analyze a cylindrical structure in FGM with properties gradated in the direction of the radius (Thickness) solicited purely in internal pressure by the implementation of a UMAT subroutine in the calculation code ABAQUS. The elasto-plastic behavior of the FGM is described by the flow theory represented by the equivalent stress of Von Mises and an incremental hardening variable. The TTO model (Tamura-Tomota-Ozawa) was used only to determine the elastic-plastic properties of the FGM material. The radial, tangential and axial stresses according to the thickness were evaluated in the first part of our work. In the second part, these stresses are evaluated under the same conditions but with the presence of a micro-cavity. The results obtained show clearly that these stresses are in direct relation not only with the thickness and properties of the FGM tube but also with the presence of the cavity.

Published: December 2021

A methodology of experimental research on hydrogen embrittlement of pipe carbon steels due to the transportation of hydrogen or its mixture with natural gas by a long-term operated gas distribution network is presented. The importance of comparative assessments of the steel in the as-received and operated states basing on the properties that characterize plasticity, resistance to brittle fracture and hydrogen assisted cracking is accentuated. Two main methodological peculiarities are pointed out, (i) testing specimens should be cut out in the transverse direction relative to the pipe axis; (ii) strength and plasticity characteristics should be determined using flat tensile specimens with the smallest possible thickness of the working part. The determination of hydrogen concentration in metal, metallographic and fractographic analyses have been supplemented the study. The effectiveness of the proposed methodology has been illustrated by the example of the steel research after its 52-year operation.

Published: December 2021

The process of damage identification in Structural Health Monitoring (SHM) gives us a lot of practical information about the current status of the inspected structure. The target of the process is to detect damage status by processing data collected from sensors, followed by identifying the difference between the damaged and the undamaged states. Different machine learning techniques have been applied to attempt to extract features or knowledge from vibration data, however, they need to learn prior knowledge about the factors affecting the structure. In this paper, a novel method of structural damage detection is proposed using convolution neural network and recurrent neural network. A convolution neural network is used to extract deep features while recurrent neural network is trained to learn the long-term historical dependency in time series data. This method with combining two types of features increases discrimination ability when compares with it to deep features only. Finally, the neural network is applied to categorize the time series into two states - undamaged and damaged. The accuracy of the proposed method was tested on a benchmark dataset of Z24-bridge (Switzerland). The result shows that the hybrid method provides a high level of accuracy in damage identification of the tested structure.

Authors: Agag Fatma , Ahmad Seleem S. E. , Sallam Hossam El-Din M.
Published: December 2021

The present experimental study includes testing thirteen reinforced concrete beams with openings at different locations to investigate the efficiency of strengthening such openings. Different strengthening techniques around the opening after and before casting include diagonal bars, upper and lower steel, and carbon fiber reinforced polymers (CFRP), were examined. All beams were made from 30 MPa compressive strength and tested under four-point loading.  The cross section of the beams is 400 mm depth x 160 mm width and beam length 2400 mm. The dimensions of the opening are 200 mm x 200 mm. The stiffness, deflection, failure load, and failure mode of the strengthened beams were discussed. Experimental results showed that the beams strengthened with upper and lower steel around opening at mid-span increase the load-carrying capacity by 16.59%. However, beams strengthened by CFRP sheets around the opening in the shear zone increase the load carrying capacity by 47.7% compared to opened beam.

Published: December 2021

The use of crushed limestone sand in the concrete industry will be quite possible and imperative for environmental reasons. Many researchers around the world have found that concrete based on 50% substitution of river sand by limestone sand gives better physico-mechanical characteristics. The main objective of this investigation is to search for an optimal percentage of silica-limestone fines resulting from the substitution of half in quantity of alluvial sand by crushed limestone sand in ordinary concrete. The proportions of fines that were tested in this work are 6%, 8%, 10%, 12% and 14%. The obtained results revealed that concrete based on silica-limestone sand and containing 14% of the same type of fines strongly improves the different mechanical strengths and participates in the reduction of 10% and 13%, of the coefficient of capillary absorption and of the porosity accessible to water, respectively, compared to the control concrete. In addition, good statistical relationships between the studied parameters were also found
Depleting Time Itself: The Plight of Today’s “Human” Environment
Authors: Robinson Nicholas A.
Published: December 2021

Earth, and its human societies, are seized with the triple crises of climate change, biodiversity loss, and pervasive and escalating levels of pollution. In the 50 years since the 1972 UN Stockholm Conference on the Human Environment (UNCHE), States and UN Environment Program (UNEP) have created an entirely new body of international environmental law, and agreed on the UN Sustainable Development Goals for further socio-economic developments to help the 7.9 billion people on Earth today, and the 1.5 more billion expected soon. The article highlights the accomplishments of the past five decades, launched in Stockholm. However, beyond depleting the resources of Earth’s natural and physical environment, humanity has also depleted time itself. There is not enough time left to permit the pace of environmental law-making to lead to success. Political will has eroded too, leaving “business as usual” to continue to harm the environment. Fortunately, most nations have recognized the right to the environment, and the UN General Assembly is asked to do so in 2022. At the same time, courts around the world are increasingly enforcing environmental rights. If courts world-wide begin to enforce the right to the environment, pathways to attaining sustainable development can be developed beyond Stockholm+50 (2022).

The methodological basis of the study was based on a productive combination of visual and graphical capabilities of BIM-technology, digital control technologies, methods of graph-analytical visualization (provided through the use of "geometric econometrics"). The resulting methodological apparatus allows the use of BIM-technologies in the organization of construction in fundamentally new positions - not only as a means of graph-analytical structuring of physical volumes of contract work, but, above all, as a modern basis for variable organizational and technological modeling of works and stages of construction. project and as a tool for managing the cycle and environment of the development project.

It is substantiated and proved that when forming the analytical basis of the construction enterprise in modern digital space it is expedient to take into account the vector of improvement of management models in the direction from single-purpose to multi-purpose, from deterministic to deterministic-stochastic, from worc-arc model (robot-arc). to the model of the synthetic type “worc & matrix” “work & top”. The successful operation and development of construction organizations participating in projects in the digital environment requires a sound approach to the formation of their competitive strategy as executors. The article highlights that the concept of competitive strategy of the contractor is a set of rules and techniques that should guide the construction organization, ready for change in its activities through the involvement of digital management format: integral elements of the process of digital transformation in construction are changes in activities of construction organizations, which consist in a full-scale digital transformation based on the company's digital development strategy. Implementing the measures envisaged by the digital strategy requires an integrated approach that includes the company's development in various areas, but understanding the trends of the digital environment and construction market will allow companies to rationally use existing digital potential and effectively identify ways to further digital development of construction companies.

Background and Aims: Children with developmental coordination disorders experience some form of impairment in some executive functions. The present study was designed and conducted to study the effect and retention of cognitive games on the development of three components of executive functions (response inhibition, working memory, and cognitive flexibility) among children with developmental coordination disorders. Methods: The present study was a quasi-experimental study with a control group. Thirty girls aged 7-10 years with developmental coordination disorder Based on the score obtained in the Movement Assessment Battery for Children-second edition (MABC-2) test set and based on the IQ score, were divided into two experimental and control groups. MABC-2 and Cattle and intelligence tests were used for initial screening, and N-Back, Stroop, and Go-NOGO tests measured working memory, cognitive flexibility, and response inhibition. The training protocol consisted of a series of purposeful cognitive and motor games that explicitly considered the development of a specific component of executive functions. Data were analyzed using a combined two-way analysis (2×3) of variance. Results: The findings showed, performance Working memory (P=0.0001) performance, cognitive flexibility (P=0.045), and response inhibition (P=0.010) increased in the experimental group from pretest to posttest, While no such change was observed in the control group. Also, the effect of improving games on working memory (P=0.0001) and response inhibition (P=0.033) was maintained until the retention test. At the same time, there was no significant difference between cognitive flexibility in the retention test of children with developmental coordination disorder in the experimental group and control. Conclusion: Based on the findings, cognitive-motor games effectively improve and maintain working memory, inhibit response, and develop cognitive flexibility. As a result, according to the results of this study and other studies, it can be acknowledged that intervention as a process as a process-oriented therapy with the involvement of the individual in a mental process improves the executive functions of children with developmental coordination disorder and games introduced in this Research is a good framework for designing and implementing high quality and reproducible programs.

Background and Aims: Perturbation training is a type of exercise in which participants frequently experience loss of balance to practice and improve control of balance reactions. Due to postural control impairment in blind people, this study aimed to investigate the effect of 4-week perturbation-based balance training on risk of falling, movement function, and balance in people with visual impairment. Methods: In the current, 30 men with absolute visual impairment were randomly divided into control (n=15) and experimental (n=15) groups. The experimental group performed perturbation exercises for four weeks and three sessions per week for 60 minutes. To evaluate the static balance of the modified stork test, the dynamic balance of the Berg balance tests, the movement function of the Tinetti test, and the fall risk of the functional reach test before and after the training intervention were used. Data were analyzed using an independent t-test and repeated measures analysis of variance at the level of α=0.05. Results: The results showed that the experimental group had an increase in the mean scores of static balance (P=0.001), dynamic balance (P=0.001), movement function (P=0.001), and decreased risk of falling (P=0.001) and is significantly better than the control group. Also, in the post-test, the findings of intragroup changes showed that the experimental group had a more significant effect on increasing balance, increasing movement function, and decreasing the rate of falling than the control group (P<0.05). Conclusion: According to the results of the present study, the use of perturbation exercises improves balance, increases the level of movement function, and reduces the risk of falling in blind people. Due to the positive effects of exercises and the benefits of this type of rehabilitation, it is recommended that this rehabilitation program be performed on the blind and visually impaired. Sports instructors are advised to use the balance-based perturbation exercises in this study and other exercises for people with visual impairment to increase their fitness.

Background and Aims Foot overpronation is one of the most critical factors that cause musculoskeletal injuries and lead to greater mechanical loads in the lower limb structure. Sand is an unstable and unpredictable surface that has particular importance in human movement mechanics. The purpose of this study was to investigate the effect of sand surface training on directed and general co-contraction of ankle joint muscles in individuals with foot overpronation during running. Methods The present study was a randomized clinical trial type. Statistical samples of the present study included 15 males with foot overpronation in the control group and 15 males with foot overpronation in the intervention group. Individuals in the intervention group performed a sand surface training program consisting of continuous jogging, striding, bounding, galloping, and short sprints for 8 weeks. Tibialis anterior and gastrocnemius medialis muscles activity was evaluated by an 8-channel electromyography system with a surface electrode during running. A two-way ANOVA test was used for statistical analysis at the significant level P<0.05. Results The results demonstrated greater ankle-directed co-contraction in the push-off phase during post-test compared with the pre-test in the intervention group during training on sand (P=0.040). Other components of directed co-contraction in the different stages and general co-contraction in all phases did not demonstrate significant differences after sand training (P>0.05). Conclusion It seems greater ankle joint directed co-contraction in the push-off phase after training protocol reduced the risks of lower limb injuries and ankle instability in individuals with foot overpronation in this phase.
