Study Design: Randomized double-blind control study.Purpose: To evaluate the effects of nefopam on reducing morphine consumption and postoperative pain in patients undergoing minimally invasive spine surgery (MISS) and to evaluate its effects on enhanced recovery after spine surgery.Overview of Literature: Enhanced recovery after surgery (ERAS) has become a major goal for spine surgery. Multimodal pain management combining non-opioid analgesics is a key element of this. However, there is little evidence regarding the use of nefopam in spine surgery as part of an ERAS protocol.Methods: One hundred patients undergoing MISS were randomized into two groups. Patients in the nefopam group received 20 mg of intravenous nefopam diluted in 100 mL of normal saline intraoperatively, followed by 80 mg of nefopam diluted in 500 mL of normal saline, given as a continuous infusion postoperatively for 24 hours. The control group received an identical volume of normal saline. Postoperative pain was managed by patient-controlled analgesia in the form of intravenous morphine. Morphine consumption in the first 24 hours was recorded as a primary outcome. Secondary outcomes regarding ERAS were also collected.Results: There were no significant differences in either total morphine consumption or postoperative pain score in the first 24 hours postoperatively between patients receiving nefopam and the control group. Morphine consumption in patients receiving nefopam was 13.54±10.64 mg compared with 15.86±16.2 mg in the control group (p=0.41). Time to postanesthetic care unit discharge, times to first sitting and walking, length of hospital stay, as well as duration of Foley catheter use and time until drain removal were also similar. There were no serious adverse effects of nefopam compared with normal saline.Conclusions: Nefopam did not significantly reduce opioid consumption or postoperative pain score. Adding nefopam as part of multimodal analgesia did not show beneficial effects for enhancing recovery after spine surgery.

Hernan Cortes. The first relation letter to the Emperor. The Spaniards in the island of Cozumel. Commented translation
Authors: Kofman Andrej
Published: March 2022

The first publication in Russian of the first letter of Hernan Cortes to Emperor Charles V with an introduction, comments and notes by the translator. Published in two articles. The introduction outlines the special situation in the creation of this letter. The formal captain-general of the expedition to Mexico, the governor of Cuba, Diego Velasquez, decided at the last moment to replace the commander-in-chief; Cortes, appointed by him earlier, refused to obey the order and arbitrarily left Cuba at the head of the expedition, thereby placing himself outside the law. These circumstances determined the genre specifics of the letter: it was created in the form of a collective report on the initial stage of the expedition and a request to approve Cortes as captain general - this was the decision made democratically by soldiers and captains. The specificity of the genre allows Cortes to present himself in the most favorable light, downplay the merits of his predecessor, Juan de Grijalva, who discovered Mexico, and denigrate Velazquez in every possible way. The fragment of the letter published in the first article tells about previous expeditions to the Gulf of Mexico and describes the stay of the Spaniards on about the island Cozumel, where they managed to get an interpreter, a Spaniard who spent several years captives in the Yucatan and mastered the Mayan language.
APHORISMS AS MEANS OF INTERPRETING OF LINGUISTIC TERMS: PECULIARITIES OF DEFINING
Authors: Odyntsova Halyna , Kondratieva Tetiana
Published: March 2022

The article analyzes the peculiarities of aphorisms functioning in linguistic scientific discourse. Linguistic aphorisms have been identified as individual authorial utterances that reflect subjective interpretation of linguistic terms. Over seven hundred aphoristic utterances were taken from scientific, academic, reference and fiction books, as well as from collections of aphorisms, where the linguistic terms have been presented. They serve as the material for research. Applied here are methods of targeted sampling, cognitive analysis and quantitative analysis, as well as descriptive method. A primary aim was to differentiate between two types of definitions of linguistic terms: scientific ones (i.e. the utterances of the primary nomination) and fictional ones, which serve the purpose of secondary nomination. The scientific definitions render the essential and core features of linguistic terms, while the fictional ones focus on the indirect and peripheral term characteristics determined by author’s communicative and pragmatic goal. Defining of linguistic terms through aphoristic utterances has been viewed as a unity of semantic, pragmatic and cognitive aspects. The research findings distinguish between aphoristic definitions-elucidations and definitions interpretations, depending on either objective-logical or expressive-stylistic information dominance. Aphoristic utterances created by linguists have been viewed as the definitions-elucidations characterized by high level of reference and frequent use of linguistic terminology that bring them closer to the logical designations or scientific definitions. Associative and metaphorical thinking forms the background of definitions-interpretations, typical for writers’ discourse. Therefore, their utterances have been considered as artistic definitions of linguistic terms, that are the means of additional semantization of corresponding notions. Such aphorisms illustrate anthropological approach to the analysis of linguistic phenomena. The secondary aim was to trace the ways of rendering the meaning of linguistic terms through aphoristic utterances. The following types of aphoristic definitions have been singled out considering the modes of explaining linguistic terms: descriptive definitions, comparative definitions (simile), definitions based on either semantic opposition or similarity.
TO THE SELFHOUSE: THE CENTRIPETAL MOVEMENT OF SYMBOLS IN VIRGINIA WOOLF'S TO THE LIGHTHOUSE
Authors: Poursanati Susan , Taheri Yasaman
Published: March 2022

Modernism is a literary movement which appeared around 1914. New technologies and the horrible effect of World War I, made many authors question the future of this modern machine (human being) who declined any kind of tradition for the sake of the new sentiment. Modernist fiction used two significant tools: one is the stream of consciousness to reveal the inner self of the characters, and the other one is employing the symbol to reflect hidden reality through the life of the characters. Virginia Woolf is considered as one of the most prominent modernist authors who employ the various modern techniques in her fictions such as To the Lighthouse. The aim of this article is followed in two different steps: first, the discussion of the roles of different symbols and signs through the whole work to reflect how these symbols function in the novel as a web of signs; and second, the exploration of the centripetal movement of various symbols and colors to show an unattainable concept of reality in modern life.
Wilde Körper: Das wilde Denken als Antwort auf die neue geo-soziale Frage
Authors: Adolphi Lukas
Published: March 2022

In dem Beitrag suche ich nach einer Antwort auf die von Bruno Latour (2019) aufgeworfene „neue geo-soziale Frage“ nach Möglichkeiten zur Etablierung einer alternativen amodernen Weltbeziehung. Dazu lese ich Das wilde Denken von Claude Lévi-Strauss (1973) neu, analysiere die Rolle des Körpers und erarbeite das Konzept des Wilden Körpers. Ich argumentiere, dass der Körper im Zentrum der umgekehrten Symmetrie von Wildem und modernem Denken steht und seine Veränderung einen gesellschaftlichen Wandel einleiten kann. Darauf aufbauend zeige ich, dass der Wilde Körper in seiner Ethik und Politik mit Latours Terrestrischem Manifest übereinstimmt. Abschließend gebe ich exemplarische Ausblicke, wie mögliche Antworten des Wilden Körpers auf die „neue geo-soziale Frage“ aussehen können.
Segurança jurídica e cumprimento de decisões da corte interamericana de direitos humanos: o caso “Gomes Lund e outros (‘Guerrilha do Araguaia’) vs. Brasil”
Authors: Abreu Eduardo João Gabriel Fleck da Silva , Santos Marcelo de Oliveira Fausto Figueiredo
Published: March 2022

Com frequência, chocam-se os valores da soberania nacional e da obrigatoriedade de cumprimento das obrigações internacionais. Para ilustrar essa situação, toma-se o caso “Gomes Lund e outros (‘Guerrilha do Araguaia’) vs. Brasil”, julgado em 2010, como exemplo, tendo em vista que, além de ainda pendente de cumprimento pelo País, vem tendo a sua decisão contrariada por tribunais nacionais. Diante desse panorama, surge a questão norteadora sobre a possibilidade de o Estado-nação desvincular-se de suas obrigações internacionais sob a alegação de soberania, bem como sobre a existência de critérios que possam balizar a conduta estatal e, com isso, propiciar maior previsibilidade, em atenção à exigência constitucional de segurança jurídica. Busca-se, como objetivo, responder a essa questão a partir de pesquisas de julgados dos órgãos de cúpula do Poder Judiciário nacional e de doutrina especializada nos campos do Direito Constitucional e dos Direitos Humanos. Nesse percurso, almeja-se compreender a estrutura e as particularidades do Sistema Interamericano, a força coercitiva das decisões da Corte Interamericana de Direitos Humanos e as características jurídicas da exigência constitucional de segurança jurídica no comportamento estatal nessa interação entre o direito interno e internacional. Isso feito, poder-se-á concluir acerca da obrigatoriedade do cumprimento das decisões do sistema regional e os efeitos deletérios que a sua inobservância causa para o princípio constitucional da segurança jurídica, bem como será possível buscar caminhos para tentar superar esse impasse.

A method to evaluate the performance of an open loop geothermal system for mine water heat recovery
Authors: Rudakov D. V , Inkin O. V
Published: March 2022

Purpose. To develop a method to evaluate hydrodynamic and thermal parameters of an open loop geothermal system with the discharge into surface water bodies as well as to test the method under real site conditions considering different technology options, geotechnical and thermodynamic factors. Methodology. We employed the relations of hydraulics and thermodynamics, performed an engineering review of open loop geothermal systems for mine water heat recovery, studied hydrodynamic and mining conditions of the colliery Novohrodivska No.2. The developed technique includes evaluating the temperature of rocks around flooded workings, the length of the hydraulic path and flow resistance of workings. Findings. The evaluated temperature of mine water entering on-ground heat exchangers ranges at 17.8 0.25 C, and the system thermal output is 1070 21 kW. Water temperature in flooded workings due to dilution with infiltration during the operation period of 25 years is expected to fall by 0.61.0 C, which decreases the thermal output by 5.68.3%. The estimated cooling of water during its rise in the shaft does not exceed 1C. The criterion of the geothermal system energy efficiency decreases from 1.8 when pumping close to the mine water level to 1.05 when pumping 460 m below the ground; the heat pump coefficient of performance (COP) reaches 5.0. Originality. The flow characteristics and hydraulic flow lengths at different horizons, the temperature of rocks around workings were found to be the dominant factors for the thermal output under steady flow. The pumping depth was proved to significantly affect the energy efficiency of the system. Practical value. The proposed method allows quantifying the energy criterion of an open loop geothermal system with the discharge into surface watercourses, which enables optimizing system performance indicators.

Published: March 2022

Purpose. To substantiate the formation conditions, distribution patterns and metallogenic specialization of low-temperature metasomatites of the Middle Dnipro megablock of the Ukrainian Shield based on the research results obtained. Methodology. The authors used a set of field and laboratory methods. Petrographic, mineragraphic, petrochemical studies were carried out. Interpretation of the results of chemical, laser microspectral, X-ray diffraction, scintillation spectral, thermal analyses is carried out. Findings. A generalized petrological description of low-temperature metasomatites of the Middle Dnipro megablock of the Ukrainian Shield is carried out, taking into account the composition of the original rocks, characteristics of newly formed mineral parageneses, metallogenic specialization and patterns of distribution of metasomatic formations. The study on occurrences of vertical and horizontal metasomatic zoning within the greenstone structures of the Middle-Dniprean region was carried out. The composition of telescoped metasomatites spatially related to the intersection of deep faults is characterized. The metallogenic specialization of low-temperature metasomatic formations is determined and the process of formation of ore concentrations of complex composition in the nodes of intersection of deep faults has been characterized. Based on the results of studies on the composition and ore content of metasomatites, an insignificant level of erosional truncation of vertical ore-metasomatic columns within greenstone structures is substantiated. Originality. The aspects of petrology and ore content of the group of low-temperature metasomatic formations of the Middle Dnipro megablock of the Ukrainian Shield have been revealed. The spatial relationship of the metasomatic areas with the systems of deep faults has been substantiated, which justifies using the identified metasomatic formations as geological indicators of deep fault zones. The features of ore content of low-temperature metasomatic formations of the Middle Dnipro megablock are characterized. It is shown that formations of telescoped metasomatites with a complex composition of mineralization are spatially associated with the intersection of deep faults. Practical value. The metallogenic specialization of low-temperature metasomatic formations has been determined, which can be used as a search criterion for various types of deposits of metallic and non-metallic minerals within the Ukrainian shield.

Authors: Sosnin K , Gerasina O , Ribalchenko Yu , Schullerus G
Published: March 2022

Purpose. Reducing the downtime of transport equipment due to technical malfunction of the chain transmission by disclosing the uncertainty in the friction change of the plate roller open-chain through the estimation of the chain friction coefficient at idle speed. Methodology. To achieve the goal, the following tasks were set: to carry out a research on the change in the plate roller chain friction at idle speed; to develop a method for evaluating friction in the roller plate chain at idle speed. Research on the state of the roller plate chain in laboratory conditions is carried out on the bench by measuring the motor torque during the rotation of the chain. Data processing of the random process of changing the state of the plate roller open-chain predetermines the use of methods of mathematical statistics and correlation analysis. Findings. The research carried out to control the state of the plate roller chain made it possible to disclose the static dependence of the change in friction per day and the correlation dependence of the change in friction in the chain for all days of the experiment. To estimate the change in the state of the conveyor chains, a method was developed for determining the friction coefficient of the plate roller chain through the torque of the motor rotating the open-chain. During the experiment, the increase in the coefficient of friction was more than 20 percent. Originality. The relation of the change in the parameter of the torque of the motor rotating the chain at idle speed during the experiment due to the change in the friction of the chain or the sliding speed in the joints of the chain was disclosed. Practical value. It consists in using the developed method for estimation of the friction in the open-chain at idle speed for planning the timing of scheduled maintenance of transport equipment. An increase in the magnitude of the motor torque that rotates the open-chain at idle speed is associated with a decrease in the sliding speed of the chain joints, an increase in the friction coefficient, which is a criterion for estimation the state of the drive chain. The results of changing the friction coefficient of the developed method showed similarity with the results of the correlation method for estimation of the state of the roller plate chain.

Purpose. To determine a legally established mechanism of criminal-legal protection of forest and land resources on the territory of Ukraine where illegal amber mining is carried out. Methodology. The methodological basis of the study is a system of general and special methods of cognition: the dialectical method was used to learn the essence of such a phenomenon as the protection of public relations for environmental protection and rational use of natural resources during amber mining; system-structural method when separating the social relations of the constituent elements protected by the law within the specified structure; when analyzing the forms of socially dangerous acts of crimes under Articles 240-1, 239 and 245 of the Criminal Code of Ukraine; logical-dogmatic method during the interpretation of certain terms used in the sciences of geology, administrative and criminal law, contained in the provisions of current legislation; comparative law method - in the study of the relationship of objective signs of acts under Articles 201-1, 239 and 245 of the Criminal Code of Ukraine. Findings. It is established that the criminal law protection of Article 240-1 of the Criminal Code of Ukraine covers public relations for the protection and rational use of amber resources, forest and land resources. The former ones are the main direct object of the crime, the latter ones are the direct additional objects of this crime. The range of objects of this crime is established amber, forest and land resources. The collision of norms of Articles 240-1 and 245 and Articles 240-1 and 239 of the Criminal Code of Ukraine. Originality. It is established that the object of the crime under Article 240-1 of the Criminal Code includes the main direct object public relations for the protection and rational use of amber resources and two direct additional objects of crime: public relations for the protection and rational use of forest and land resources. It is determined that damage to forests due to illegal amber mining must be further qualified under Part 1 of Article 245 of the Criminal Code of Ukraine if illegal mining is carried out in a generally dangerous manner. This crime must be further qualified under Part 1 of Article 239 of the Criminal code of Ukraine if illegal extraction of amber is carried out with violation of special rules of treatment of substances, waste or other materials. Practical value. From a practical point of view, the results of the study will contribute to the correct qualification of practitioners of illegal amber mining in Ukraine.

Published: March 2022

Purpose. Improving the efficiency of the system by increasing the accuracy in determining the drilling objects spatial orientation, as well as adjusting the system components to more accurately isolate the information signal from the angle transducer. Methodology. A comprehensive increase in the angle transducer accuracy is based on taking into account the influence of factors and errors in determining the drilling objects spatial orientation, as well as a possibility of smoothly tuning the characteristics of the receiving part due to the departure of the information modulated signal frequency from the angle transducer. Findings. Given the converters operating condition, the error in measuring the zenith angle (deviation angle from the vertical) does not exceed 0.3, the installation angle of the deflector is 3. In addition, restructuring the frequency-dependent components characteristics of the systems receiving part allows one to make changes quickly and improve the overall system. Originality. A comprehensive solution to the problem of increasing the control system efficiency is to increase the converter characteristics, by taking into account its errors and operating conditions, as well as increasing the smoothness and tuning the characteristics efficiency of the receiving part, due to the possibility of calculating the transfer function coefficients using simplified ratios, which will greatly simplify the process of processing information and improve the quality of inclinometric work. Practical value. This complex solution is brought to the design, manufacture and experimental converter verification, and algorithms and programs for tuning frequency-dependent components are proposed and brought to implementation.

Authors: Horban O , Protsenko O , Tytarenko V , Bulvinska O , Melnychenko O
Published: March 2022

Purpose. To examine the mechanism of managing changes resulting from the promotion of a new value system by higher education institutions. Methodology. The research is based on the methods and tools of cultural economics, which allow the authors to comprehensively reveal the relationship between the value system and behavior, on the one hand, and the changes caused by values and behavior, on the other hand. The authors used the methods of modeling, comparative analysis, strategic and systematic approaches to the analysis of economic and managerial organization of the cultural sector and the behavior of producers and consumers. Findings. The study proved that: 1) the value system and its manifestations in practice signal the readiness of city residents to accept or reject changes; 2) the success of promoting a new value system depends on the alignment of the initiative to change the existing value system with the values of the change recipients; 3) the inconsistency between the value system that is being promoted and the recipients values shall be eliminated by means of communication with the change recipients. Communication aims to remove anxiety from expected changes and make the changes attractive to the recipients; 4) anxiety shall be remedied by the messages convincing the change recipients of the positive effects of changes on their value system and of the negative consequences if the recipients reject changes. Originality. The application of Schwartzs Theory of Basic Values and the model of Lngstedt and Manninen allowed the authors to explore the mechanism of managing changes resulting from the promotion of a new value system by a higher education institution. Practical value. The obtained results allow for the effective use of the methods and tools of cultural economics in the formation and promotion of a new system of values by a higher education institution.

System approach is applied to classify energy audit of coal mines in terms of the following criteria: functioning phases of the audited entities; nature; scope of the audited entities; auditing methods; class of the involved problems; and auditing entities. Casual connections between individual ranking of energy efficiency and individual potential energy efficiency of coal mines have been determined; and dependence function of overall rankings of coal mines and sectoral potentials of their energy efficiency potentials has been formalized. Dynamic approach to identify subjects of financial and accounting support of marketing strategies of coal mines is applied in the form of energy efficiency potential progress. Practical value. Recommendations concerning the development of the basic program document on the energy management of coal mines have been substantiated in the form of Order for energy policy to identify the key energy efficiency indices as well as responsibility for their achievement. Details for such its sections as Energy accounting, analysis, and audit, Marketing support of energy policy, and Financial and investment support of energy policy have been proposed.

Purpose. To develop a methodological approach to assessing the level of sustainable development of a machine-building enterprise. Methodology. To achieve this goal, a set of general scientific and special methods was used: induction and deduction, logical generalization, system analysis and formalization of complex structures, economic and mathematical modeling. Findings. A methodical approach to assessing the level of the enterprises sustainable development is proposed, which involves determining the integrated indicators of development of its subsystems, the overall integrated and four-dimensional indicator of sustainable development. On the basis of integrated indicators of economic, environmental, social and energy development, calculated using BSC-model indicators, a four-dimensional indicator of the level of the enterprises sustainable development is formed, for which it is necessary to compare the degree of achievement of the goals of sustainable development of the enterprise with the previous year. This indicator allows determining further scenarios of enterprise development in accordance with the feasibility of attracting new resources and redistributing them between subsystems. This methodological approach was tried at a machine-building enterprise; the results obtained allowed us to conclude that in 2020 it was possible to achieve more goals of sustainable development in the economic and energy subsystems. The value of the integrated indicator points to a more sustainable development of the enterprise in 2020 than in 2019, the growth of the integrated indicator of sustainable development of the enterprise is due to the economic and energy subsystems. Originality. The methodical approach to the complex assessment of the sustainable development level of machine-building enterprises is improved on the basis of the developed integrated indicators of economic, ecological, social and energy development, which, unlike the existing ones, allows determining the degree of achievement of goals for each subsystem of sustainable development; identifying ways of resources redistribution between the sustainable development subsystems on the basis of a four-dimensional indicator of the sustainable development level in order to use them most effectively; outlining priorities for further development. Practical value. The use of the proposed approach will give companies the opportunity to determine the degree of achievement of goals for each sustainable development subsystem, ways to redistribute resources between them in order to most effectively use them, to form scenarios for further development of machine-building enterprises.

Published: March 2022

Purpose. To develop a model of investigating the link between the level of shadow economy and indicators of social development of the country. Methodology. The study of the relationship between the analyzed indicators was conducted using general and special research methods. The established hypotheses were tested using VAR/VEC modeling. Dickey-Fuller test, the Phillips-Perron test, Joansen test are used in the work. Findings. The paper identifies the risks of the shadow economy for social indicators of macroeconomic stability. Based on the analysis of the countrys social development indicators, indicators were identified that are most sensitive to changes in the level of the shadow economy which are: Gini coefficient, average income ratio of 10% of the richest to 10% of the poorest, average income ratio of 20% of the richest to 20% of the poorest sections of the population, Human Development Index, gross average wage. The EU countries and Ukraine are identified as the statistical base of the study and the assessment period is 20052020. The results of modeling proved the relationship between the level of shadow economy and indicator of social development. Originality. The approach to assessing the relationship between the level of the shadow economy and indicators of social development of the country by considering the indicators that most fully characterize the level of social protection and material well-being of the population has been improved. Practical value. The scientific contribution of the paper is that existing research on the impact of shadow economy on the level of social development of the countries remains fragmented, as well as studies assessing its effect on the macroeconomic stability. The impulse response function constructed by the authors may provide some insight into better understanding of the indicators of social development, the most sensitive to the shadow economy shocks. The results of estimation can be used for practical or scientific purposes.

Background: The whole world is going through a grim crisis instigated by the Novel Coronavirus (COVID-19) pandemic. Health systems of Bangladesh are overburdened in response to the disease. Healthcare workers (HCWs) are at a high risk of getting the infection and the source of transmission in the community.
Objectives: This study was designed to explore the real scenario about knowledge, perception and practical behavior about COVID-19 among healthcare professionals of Bangladesh to combat the pandemic during the first outbreak of the COVID-19 pandemic in Bangladesh. Findings of this study might be utilized for the promulgation of policy and program for upcoming days.
Materials and Methods: This cross-sectional survey was conducted among the adult Bangladeshi healthcare professionals of purposively selected three type of healthcare facilities- a Tertiary level hospital: Bangabandhu Sheikh Mujib Medical University as well as District hospital and Upazila health Complex from highly infected district Narayangonj and low infected district- Brahmanbaria. A number of 241 HCWs were interviewed using a semi-structured self-administered questionnaire electronically via-email, Facebook Messenger or other social media communication.
Result: It is observed that knoledge level is higher among the elder people (age >40 years) than the young people (age <30 years) (10.84±0.48 vs 10.13±1.39, p value is 0.003 at 1% level of confidence). Although there was no significant difference in attitude among them (Attitude score in age >40 years vs <30 years age group was 3.24±0.96 vs 2.96±0.635 with p value is >0.05 at 5% level of significance).
Conclusion: To reduce the risk of infection among health care professionals who are not in direct contact with patients. Policy and education should be implemented to convey the importance of possible exposure to the virus.
