Grassroots as an Artistic Category of Ukrainian Culture of the XVII–XIХ Centuries
Authors: Dubrovnyi Taras
Published: December 2022

The purpose of the article is the classification of Ukrainian musical culture, which, unlike other artistic genres, has not received clear musical definitions for a long period of time. This is connected with socio-cultural and historical circumstances, when music was primarily perceived as a part of liturgical rites, everyday life, and other circumstances, and in this context was interpreted as part of something bigger, a whole. Therefore, the assessment of musical art as a single category needs clarifications and definitions. The research methodology is based on historical, cultural, and artistic levels. The scientific novelty consists in the introduction of the term Grassroots into scientific circulation to describe and define the quality of musical productions. Conclusions. For a more appropriate definition and characterisation of the musical creativity of the 17th-19th centuries, the term Grassroots, in our opinion, is the most successful and appropriate. It clearly demonstrates the development of national musical art as "grassroots", at the same time taking it out of the realm of primitiveness and dilettantism, which metropolitan cultures have tried to impose on us over the centuries. At the same time, the aesthetic tension is relieved when characterising works through the prism of kitsch means and tools, as well as its definition as "low" or "grassroots", since the adaptation of the achievements of European art on national material required a certain time for formation and development. Therefore, Grassroots art is the most appropriate term to describe and classify the rich heritage of Ukrainian musical art.

). Synthesis of Philosophical-Aesthetic and Psychological Narratives in Modern Ukrainian Composers’ Creative Work
Authors: Stepurko Viktor
Published: December 2022

The purpose of the article is to determine the creative approach in composer activity and the perception of musical images, which lies in the aesthetic principles of individual creativity. The factors that influence this approach are the characteristics of human psychology and cognitive activity, the degree of synthesising worldview and artistic information, the individual’s sociocultural activity, and the effectiveness of their assimilation of the previous civilisational experience. The research also aims to investigate new ways of summarising information in the art of music, in connection with the introduction of the philosophy of pluralism and postmodern aesthetics in society; consider the phenomenon of influence on the consciousness of the composer of video-informational digital technologies. The research methodology lies in the analysis of the mechanisms of creativity, in particular in the systematic approach to the specifics of the aesthetic and psychological impact on modern society of "tying" sound forms to visual framing. Besides, it is based on studying the specified problem from different points of view: on the analysis of the inner impulses of the artist's own "I", solving professional tasks of the development of the musical genre, social challenges, which are realised by the creative personality as a real necessity, taking into account the transition from auditory verbal to synthetic perception of a musical work at the level of the synesthetic component and mystical suggestions. The scientific novelty consists in the generalisation of worldview and artistic information based on the sociocultural activity of the individual based on previous experience, the use in musicological analysis, in addition to the philosophical-aesthetic, but also the narratological approach, the identification of the conceptual sphere of creativity, its worldview, historical, ethno-national, psychological content, which is due to modern creative technologies. Conclusions. The sociocultural significance of composer creativity as a special type of activity, as a result of which new material and spiritual values arise, lies in the importance of its psychological and philosophical understanding for self-realisation, disclosure and understanding of the horizons of one's own spiritual life. Cathartic and compensatory processes of this direction of creative activity in the general human, historical-cultural, and individual sense contribute to the formation of a new socio-psychological reality of culture.

Genre and Style Innovations in Creative Works of Ukrainian Pop Singers
Authors: Ovsiannikova Nataliia
Published: December 2022

The purpose of the article is to define genre and style innovations in the creative works of Ukrainian pop singers. Research methodology. In order to achieve the set tasks, a number of general scientific methods have been used in the paper. The theoretical method has been used to clarify the terminology of the research; the analytical method has been applied to study the components of the vocalist's work. The biographical method has been used to study individual figures in modern pop music of the 21st century; the comparative and theoretical generalisation methods have enabled summarising the results of the research. Scientific novelty of the study consists in highlighting the main genre and style innovations of the modern Ukrainian pop song. Conclusions. In the modern pop music environment of Ukraine, there are dozens of musical projects and artists working in different styles and directions. The modernised system of domestic pop music, as part of the mass market of the entertainment industry, has introduced a system of a unified product, namely a musical hit, which nullifies the performer's efforts to express themselves, and has created a need for brightly personalised musical projects. The concepts of genre and style are in a close relationship. Style characterises long stages of musical art development, represents a national or other stylistic unity, and is changeable. Genre is a more stable concept that can retain its characteristics for centuries. Modern Ukrainian pop music is a synthetic fusion of two directions, such as rock and pop styles with interspersed national melos and folklore.

Syncretism of Song-Aria-Hymn in Solo Numbers of K. Orff's Primitivist Thinking
Authors: Song Rui Shan
Published: December 2022

The purpose of this article is to determine the genre components of solo fragments of K. Orff's singing based on the material of the arch-popular numbers from "Carmina Burana" cantata and «Die Kluge» («Intelligent woman») opera, intended for soprano, which, based on the timbral-register and texture-range indicators of singing, we specify in the features of the lyric. The methodological basis of the research is the intonation approach in the traditions of the school of B. Asafiev in Ukraine, as presented in O. Markova’s and O. Muravska’s works, Liu Bingqiang, Wang Minjie in China, in which a comparative stylistic and hermeneutic-content analysis of the expressiveness of vocal acquisition constitute the dominant factor of research methods. The scientific novelty of the work is determined by the original perspective of the study of the genre section of K. Orff's works, as well as by the identification of the timbre and role of the lyric soprano in the analysed vocal formations. Conclusions. The vocal fragments from K. Orff's cantata and opera highlighted in the analysis demonstrate the hymnic and aria basis of the song presented, as the name suggests, in "Carmina Burana" ("Beuron songs"), while the number from the part of the Intelligent Woman from the opera of the same name is based on an aria, but contains signs of both a song (lullaby) and an incantation with hymnal endings. The presence of hidden polyphony in the melody emphasises the ariad background of the expression, in which the tenderness and sobriety correspond to the timbre-function capabilities of the lyric soprano.

Influence of Scenography Development on Artistic Interpretation in Plastic Directing
Authors: Nykonenko Ruslan
Published: December 2022

The purpose of the article is to reveal the specifics of the development of scenography in plastic directing and its influence on artistic interpretation in the context of the peculiarities of theoretical developments and practical implementation in stage practice of leading theatre directors of the 20th – early 21st centuries. Research methodology. The research is based on modern art history and philosophical concepts of the study of the phenomenon of development of unique forms and the principles of the artistic relationship between direction and scenography. Taking into account the interdisciplinary nature of the issue, the cultural-historical method has been applied in research and analysis of the pictorial-plastic solution of the performance (to define the concept of "plastic stage forms" and "plastic drawing of acting" in the context of cultural, art history and philosophical concepts). The method of comparative analysis has been applied to combine methods and ways of representing scenography in theoretical works and practical activity of leading theatre directors. The typological method has been used to identify the factors of formation of the performance plastic solution. Scientific novelty. An art-historical study of the stage space approximation to the forms of the human body in the context of the specifics of theatrical art is carried out. The process of the transition of scenographic design from detached to dynamic in the context of transformational processes of theatrical art is considered. Common and different values, as well as forms of scenography representation in the theoretical works and practical activities of leading theatre directors of the 20th – early 21st centuries, are identified and analysed. Conclusions. The issue of artistic space in the organisation of the temporal component of the stage production plays an extremely important role in plastic directing, namely the circumstances that determined the specificity of the spatial structure of the literary original source or the director's interpretation and, accordingly, have an impact on its artistic and figurative interpretation. In the Ukrainian theatrical art, the relationship between directing and scenography is expressed as a sole management of all means of scenic expressiveness, namely plastic directing, which is based on the plastic unity of the stage work. The uniqueness of the scenography of the leading Ukrainian directors’ productions of the late 20th and early 21st centuries manifests itself in the artistic interpretation of the selected literary material and the innovative detection of the semantic and content saturation of their formal and plastic solution.

Hubs as Innovative Element of Sociocultural Space
Authors: Senko Tetiana
Published: December 2022

The purpose of the article is to studyhubs, their main functions, features, as well as to determine their place and role in the hierarchy of modern socio-cultural space. The research methodology is based on the application of an interdisciplinary approach to the problem and a set of the following methods: analytical, comparative, cultural, and structural-logical. Scientific novelty. The functioning of hubs was comprehensively analysed in the context of the latest trends in the socio-cultural sphere; types of cultural spaces are designed; the concepts of «creative», «youth», «social», «bibliohub» have been analysed. Legal documentation regulating the activities of individual cultural hubs has been reviewed; an analysis of the current state of implementation of hubs in domestic cultural practice has been carried out. Conclusions. As a result of the conducted research, it was established that with the wide use of the term «hub», there is no clear and unambiguous definition of this concept. Based on the opinion of researchers, modern experience can be characterised as a centre where communication and cooperation are concentrated, where various resources are concentrated, education and training occurs, experience is gained, new ideas are accumulated, the implementation of which requires the unification of like-minded people and intellectual development. The activity of innovation centres can be manifested both in real and virtual space. By location, the hub can be created: on the basis of free space; virtual, located online on special servers; combined, with a combination of features of real and virtual hubs. In the socio-cultural sphere, this term means «centre of activity», «event centre», or «meeting ground». Hubs are defined by their structure, set of services, direction of activity, and location. According to the criteria, the following types of hubs are distinguished in the field of culture: creative, youth, library, educational, and social hubs. In global practice, hubs are in demand and popular. As for Ukraine, their spread is only gaining momentum. In general, it can be argued that cultural spaces, hubs, and co-working spaces play an important social function and are centres of development and leisure that become part of people's everyday life. These centres are actively spreading and developing in domestic socio-cultural practice.

Key words: hubs, creative hubs, library hubs, youth hubs, socio-cultural space, co-working spaces.

Criminal Cases of Czechoslovaks – Victims of USSR Repressions
Authors: Dvořáková Jiřina
Published: December 2022

The purpose of the article is, on the basis of documents that relate to Czechoslovaks arrested by the Soviet authorities, executed, or sent to the Gulag, to trace their fate and analyse the base for creating the “image of a criminals”, who was punished despite their origin or views. This work is an attempt to analyse the documents we have, obtained from Ukrainian archives. The research methodology is based on an analytical approach to specific cases, selected for certain periods or types of punishment. In particular, these are the files of Hryhir Krutyi, executed in 1937 in Kyiv, Mikuláš Végh and Chaskel Brückel, who crossed the border into the Soviet Union at the beginning of World War II and were sent to the Gulag, Kurt Rosenzweig, one of the Czechoslovak Jews transported to Nisko (Poland), who were forced to cross the border into the USSR at the command of the Nazis, and Volodymyr Pasichnyk, who was arrested after the end of the Second World War in Czechoslovakia by SMERSH and forcibly transported to the USSR. The analysis is based mainly on the texts of archival documents with attention to the reliability of the facts stated in them. The scientific novelty of the work lies in the approach to research – focusing on the content of documents and the evidence part, which rarely attracts the attention of historians. In this context, the files of Czechoslovaks, victims of Soviet repression, have not been studied yet. Conclusions. Based on the analysis, it was possible to trace not only the individual fates, an important part of the common and unknown history, but also the way of making decisions by the Soviet authorities, which sent innocent people to their deaths.

Authors: Zagumenna Vira , Kuzmenko Olena
Published: December 2022

The purpose of the work is to outline the main meaningful components of information-analytical activity (IAA), in this context, to show the process of evolution of the IAA discipline in response to the challenges of the information society and its need for new specialists with new knowledge competencies in the conditions of digitisation. The research methodology consists in the application of a complex of general scientific and special methods, namely: analytical and synthetic processing of information, abstraction, generalisation, logical and systemic approaches, terminological and historical methods, as well as comparison and interrelationship of theory and practice. The scientific novelty of this work lies in the expansion of ideas about the role of the discipline "Information and analytical activity" in the formation of competences in the training of specialists in the specialty "Information, library and archive" and their influence on the development of modern society in the conditions of informatisation and digitisation. Conclusions. The analysis of scientific publications on the development and functioning of information and analytical activities in society, the study of relevant regulatory documents, in particular, educational and professional programs and educational standards, curricula for the specialty "Information, library and archival affairs" shows that, that the discipline "Information and analytical activity" (or "Information analytics") will continue to be in demand in the process of training applicants of the specified direction. Firstly, this is due to the fact that the processes of information and analytical activity permeate the activities of all information institutions and other organisations, which in one way or another are related to work with information and various documents. The need for information and analytical products of libraries and other information institutions is due to the objective request of users to get an idea of the main trends of changes in the meaningful filling of large masses of information in response to the challenges of the digital society. Secondly, the widespread development and implementation of information and communication technologies, the emergence of new types of documents and information carriers, a new level of evolution of analytical technologies, require future information specialists to have a deep knowledge of information and analytical processes and high level of digital competence. This will ensure the flexibility and adaptability of the educational system to new types of professional activity that appear as a result of digital transformation.

Authors: ÇALIŞKAN Sena
Published: December 2022

This study examined the relationship between high school students' self-efficacy levels, problem-solving skills, and perceived social support. A total of 199 high school students, 152 women, and 47 men, participated in the study. Data were collected with the Self-Efficacy Beliefs Assessment Scale, the Problem Solving Skills Inventory, and the Multidimensional Scale of Perceived Social Support. While correlation analysis was performed to determine the relationship between variables in the study, regression analysis was performed to determine whether social support and problem-solving skills predicted self-efficacy levels. In this context, first of all, the data were examined in terms of regression assumptions and it was seen that the data were suitable for regression analysis. Besides, whether the level of self-efficacy differed remarkably according to gender was examined with the independent sample t-test. As a result of the research; according to the correlation analysis, it was found that there is a negative relationship between self-efficacy and a hasty approach with one of the problem-solving skills, and a positive relationship with other problem-solving skills. On the other hand, as a result of the analysis, there was a positive relationship between the support of friends and self-efficacy, which is one of the sub-dimensions of perceived social support. Still, there was no significant relationship between family and an important person’s social support and self-efficacy. As a consequence of the regression analysis, it was discerned that the perceived social support types of friend social support and problem-solving skills of the hasty and evaluative approach significantly predicted the self-efficacy level of high school students. Yet, other problem-solving skills and social support types did not. Furthermore, as a result of the independent sample t-test, it was perceived that the self-efficacy level did not differ profoundly according to gender and the average self-efficacy levels of the girls were lower than the average of the self-efficacy levels of the boys.

Authors: KAYIN Nilay , TURAN Ferzat , AYDEMİR Emine Serap
Published: December 2022

As a result of the rapid increase in the world population, the problem of balanced and adequate nutrition has emerged, and at this point, the importance of animal production has increased even more. In this respect, there is a need to increase the cultivation areas of forage crops, as well as the correct management and reclamation of pastures for adequate and balanced nutrition of our existing animals. For this reason, forage pea (Pisum sativum L.), which has high nutritional value and is preferred by animals, is an important forage crop to meet this need. Salinity significantly limits the growth of the plant and causes yield losses. This abiotic stress negatively affects forage peas. In order to reveal the differences in the germination of forage pea varieties at different salt concentrations and the differences in the physical properties of the roots and seedlings, the effect of different salt concentrations on nine different varieties of forage peas was carried out in Bilecik Şeyh Edebali University, Faculty of Agriculture and Natural Sciences, Agricultural Research and Biotechnology Center Laboratories in 2022. In the research, the effects of nine different field types (Ürünlü, Töre, Ateş, Guifredo, Taşkent, Özkaynak, Kurtbey, Uysal and Nany) at one control and eight different salt concentrations (25, 50, 75, 100, 125, 150, 175 and 200 mM) on germination and seedling growth were examined. The experiment was carried out according to Completely Randomized Factorial Designs with 3 replications. In the research; germination speed and power, root dry and fresh weight, root dry and fresh length, seedling dry and fresh weight, seedling dry and fresh length were examined. According to the results obtained, a significant decrease was observed in germination rate, germination strength, root-shoot length and wet-dry weights of forage pea varieties due to increasing salt concentration. It has been determined that Tore field pea variety has the highest germination rate and power. Tore field pea showed 100% germination speed and power up to 150 mM salt concentration. In addition, Töre variety is followed by Ateş variety in all parameters. The varieties with the lowest germination rate and vigour were Guifredo and Uysal. As a result, the growth of forage pea varieties slowed down due to increasing salt concentration.

In the personal or individual green finance dimension, green mortgages, green home loans, green commercial building loans, green car loans and green credit cards are the most prominent green financing. When environmental green financing products related to firms are analyzed, we come across some products such as green project finance, green securities, green technology leasing, carbon finance. Eco fund and carbon fund in the asset management section, car insurance, carbon insurance and green insurance in the insurance section. Considering that our environment is essential for all humanity, supporting and increasing green financing products that are environmentally sensitive will make more positive contributions both our country and the world.
Mathematical Model of the On-Board Antenna of Reentry Spacecraft Taking into Account Surface Waves
Authors: Mikhailov V. F. , Mazhnik I. V.
Published: December 2022

Introduction. The onboard antennas of the returned hypersonic aircraft are weakly directional, which is achieved by radiation from the open end of the waveguide. When passing through dense layers of the atmosphere, they are exposed to aerodynamic heating, for protection from which a heat-resistant radio-transparent thermal protection is used. The case of uniform thermal protection of the antenna can be interpreted as the absence of heating or heating uniform in the thickness of the thermal protection.

Aim. The problem of obtaining an analytical description of the radiation characteristics of a circular waveguide closed by a flat homogeneous dielectric plate is solved. Since in such a formulation it is necessary to consider the resonant domain, a strict solution of Maxwell's equations is required.

Materials and methods. Of the known analytical methods of solution, it is possible to use the method of integral transformations and the method of eigen functions. Both of these methods are used in the work. In this case, the assumption is used that the electrical parameters of the dielectric plate (thermal protection) and the geometric dimensions do not depend on time.

Results. The relations describing the directional pattern of a circular waveguide with dielectric thermal protection and taking into account the electrical parameters of thermal protection and its thickness are obtained. Expressions are also obtained for the fields of lateral, surface and outflow waves, from which it is possible to calculate the power output by these fields. Relations for the separation of singular points of integrand expressions into poles corresponding to surface, outflow and lateral waves are obtained. Surface, outflow and lateral waves can have a certain effect on the radiation pattern. To determine this conclusion, analytical relations are obtained for determining the poles of integrand expressions that fully describe surface, outflow and side waves. All the analytical results obtained correspond to Numerical calculations were carried out on some of the obtained ratios.

Conclusion. The results showed that the power of the side waves is zero. It also follows from the calculations carried out that there is no radiation field of surface and outgoing waves, i.e. there is no contribution of them to the radiation pattern.
Selecting a Programming Scheme for Memristor Elements
Authors: Bukvarev E. A. , Fomina K. S. , Shchanikov S. A.
Published: December 2022

Introduction. An array of memristive elements can be used in prospective neural computing systems as a programmable resistance (analog multiplication factor) when performing operations of analog vector multiplication, discrete in time. To form the required resistance, the memristor should be subjected to a programming procedure. This article discusses conventional programming schemes and proposes a new versatile programming scheme for memristor elements.

Aim. To identify or develop an optimal programming scheme for memristors by analyzing the advantages and disadvantages of existing methods.

Materials and methods. The programming procedure can be carried out using either SET or RESET, depending on a different direction of movement according to the volt-ampere characteristic of the memory and its transfer to a particular state. The programming process is controlled in the LTspice circuit modeling program.

Results. Typical programming schemes of memristors were analyzed; advantages and disadvantages of existing methods were revealed. A new versatile circuit based on a variable resistor was proposed. The circuit was simulated both under a fixed resistance of the variable resistor and when varying the memristor resistance values within their permissible range.

Conclusion. In comparison with the RESET mode, the SET programming mode provides for a greater linearity of variations in the memristor resistance. The use of a circuit based on a variable resistor and a bipolar voltage source allows programming of any type and eliminates the need for recommutation of the memristor. The simulation results confirm the feasibility of the proposed method. The proposed circuit can be complemented not only with a comparator, but also with an ADC. This will provide the possibility of selecting various means for measuring the memristor resistance both during programming and for the purpose of monitoring the memristor resistance at the end of the procedure.
Nonlinear Inertial Diode Model Considering the Dependence of Nonequilibrium Charge Carrier Lifetime on Direct Current to Improve Simulation of Radioelectronic Equipment
Authors: Shevchenko G. M. , Semyonov E. V.
Published: December 2022

Introduction. Adequate modeling of semiconductor devices with a p–n-junction in reverse bias represents a relevant research problem. The existing quasistatic and non-quasistatic models fail to provide a satisfactory description for the dependence of nonequilibrium charge carrier lifetime on current density. This leads to significant simulation errors (tens of percent) at pulsed broadband signals. Simulation errors arise, because the existing models regard the lifetime as a constant value.

Aim. To propose and investigate an equivalent circuit of a p–n-junction considering the dependence of the lifetime of nonequilibrium charge carriers on direct current, with the possibility of its simple integration into CAD.

Materials and methods. The study was carried out on the example of a fast recovery silicon diode BAS16J with a p–n-junction manufactured by Nexperia. A modified diode model is proposed in the form of an equivalent circuit that considers the dependence of the lifetime of nonequilibrium charge carriers on the direct current of the p–njunction at high injection levels.

Results. The discrepancy between the experimental and simulated curves did not exceed ±9 % under pulsed diode operation. The extraction of parameters in the proposed model is carried out conventionally, from the current-voltage and capacitance-voltage characteristics of the diode.

Conclusion. The proposed non-quasistatic equivalent diode circuit can be used when designing radio electronic devices operated at short-pulse broadband signals. The proposed diode model can be easily implemented in modern CAD systems at the user level.

Introduction.Road transportation is increasingly becoming the main source of air pollution in cities. The problem of assessing air quality and modeling the dispersion of pollutants in the atmosphere requires improved models and methods. In particular, modern literature justifies the need to estimate the presence of particulate matter in the atmosphere along with the components of exhaust gases. Air pollution in residential zones should be comprehensively assessed using algorithmic and software support, taking the main factors of pollution into account.

Aim.Development of an algorithm and its software implementation for calculating pollutant mass emissions released by traffic flows. The developed algorithm can be used for modeling the level of urban pollution.

Materials and methods.The approaches of measurement theory, systems theory, statistical analysis, and mathematical modeling were applied.

Results.The methods currently used for assessing the impact of urban road network characteristics on air pollution levels were analyzed. The existing approaches to road classification were considered. Significant characteristics affecting pollutant emissions were identified, including those related to road construction, traffic flows, and urban environment. An algorithm and a software module for calculating pollutant mass emissions released by traffic flows were developed.

Conclusion.The developed module for calculating pollutant mass emissions released by traffic flows comprises an integral part of a system for modeling atmospheric air pollution in urban residential areas. The developed software can be used in environmental monitoring, assessment, and forecasting of air pollution to identify areas of concern and implement effective managerial solutions.

The substantiation of the use of antioxidant compounds to correct the reproductive capacity of males is an urgent problem of modern reproductive science. Some amino acids have pronounced antioxidant properties, including N-acetylcysteine (NAC). The work aimed to determine the effect of oral administration of NAC on sperm quality and hormonal balance in infertile boars. According to the results of andrological dispensation, three groups of animals were formed – I experimental groups (n = 5) and II (n = 5), with reduced reproductive capacity, and control (n = 5) with total reproductive capacity. The animals of the experimental groups were orally administered NAC at a dose of 75 mg/kg body weight (test I) and 50 mg/kg body weight (test II) for 30 days. With the introduction of different doses of NAC, an improvement in the quality of the ejaculates of the boars of the experimental groups was observed. In I experimental group, on the 120th day of the experiment, a probable increase in motility by 35.5 %, ejaculate volume by 8.7 %, and concentration by 5.1 % were established (P ˂ 0.05). On the other hand, the content of spermatozoa with morphological abnormalities probably decreased (by 22.7 %, P ˂ 0.01). Similar changes were obtained in boars of the II experimental group – the number of morphologically abnormal cells probably decreased – on the 90th and 120th day of the study by 17.7 % (P ˂ 0.05) and 24.7 % (P ˂ 0.01), respectively. Sperm motility and ejaculate volume increased significantly – by 28.1 % (P ˂ 0.01) and 7.9 % (P ˂ 0.05). The use of NAC contributed to the normalization of the endocrine function of the gonads, as a result of which an increase in the level of total testosterone in the blood serum of boars – an experimental group I was established by 16.3 % (P ˂ 0.05) on the 30th day of the study and by 33.7 % (P ˂ 0.001) on the 45th day. Similar changes were obtained in the animals of the II experimental group – an increase in testosterone level by 13.8 % and 29.8 % on the 30th and 45th day of the experiment, respectively (P ˂ 0.05–0.01). The estradiol level tended to decrease on the 30th day of the study. In contrast, on the 45th day, it was significantly lower than before administration by 13.6 % and 12.3 % in animals of I and II experimental groups, respectively (P ˂ 0.05). Testosterone-estradiol ratio up to 7.4–8.2 units on the 45th day of the study, which indicated the normalization of the balance of sex hormones in the body of boars. The obtained results recommend NAC as an effective means of correcting infertility in boars.

Introduction: Tuberculosis is a chronic and progressive infection, often with a latency period following the initial infection. Clinical manifestations include productive cough, hyperthermia, weight loss and malaise. Method: This is a quantitative research, data were collected from the database of the Notifiable Diseases Information System (SINAN)[14] database, the analyzed variables: schooling; breed; sex; age range and type of entry. Result and Discussion: Males have the highest percentage, representing 67.1%. The age range was between 20 and 39 years old, totaling 43.5%. There is a high prevalence of notification of new cases among the types of entry, totaling 83.1%. The predominance of cases is found in the brown race with a percentage of 81.2% and when related to education the highest number is of those who have completed high school, with 29.4%. Conclusion: In view of this, there is a need for government intervention for more exposed groups, application of public policies aimed at this vulnerable public and the entire population of the municipality, aiming at the prevention, treatment and recovery of the disease.
Filtry Słowiańszczyzny. Prolegomena (Część I)

The main aim of the article is to reflect on the features which define Slavic studies as a scientific discipline and to trace how they can, as an autonomous discipline, meet the challenge of developing their own research method. I put forward a the­sis according to which Slavic studies constitute a kind of research filter whose application (due to its properties and origins, i.e., specialization in the area of Slavic observations) allows for a more accurate study within the space of culture thanks to a more valid (i.e., wider and deeper) recognition of the specific pattern resulting from the presence of Slavs in European history. The article aims to prove that in order for an unobjectionable distinction of Slavic studies as a specialized discipline to emerge, their hermeneutical character must be recognized. Slavic studies as a hermeneutical filter can enter into scientifically fertile and satisfactory correlations with other disciplines and scientific fields, thanks to which they gain a significant extension of their own research procedure.
