У статті запропонований простий метод оптимізації та розробки поляризаційних пристроїв с діафрагмами за допомогою методу еквівалентних мікрохвильових схем. Принцип методу полягає у розбитті схеми хвилеводного пристрою обробки поляризації на прості еквівалентні схеми. Кожна схема описується своїми матрицями розсіювання та передачі. Далі основні характеристики представленого пристрою виражаємо через елементи загальної хвильової матриці розсіювання. До базових електромагнітних характеристик пристрою належать такі: фазові, узгоджуючи та поляризаційні. Було розроблено поляризаційний пристрій із трьома діафрагмами на основі квадратного хвилеводу. У діапазоні частот 13,0-14,4 ГГц було здійснена процедура оптимізації електромагнітних характеристик. Сконструйований хвилевідний пристрій у робочому діапазоні частот підтримує диференційний фазовий зсув у межах 90° ± 4,0°. Пікове значення його коефіцієнта стійної хвилі за напругою приймає значення 2,04. Максимальне значення коефіцієнту еліптичності становить 0,6 дБ, а мінімальній рівень кросполярізаційної розв’язки становить 29,5 дБ. Для перевірки правильності отриманих результатів була здійснене числове моделювання пристрою із використанням методу скінченного інтегрування в частотній області та методо скінчених елементів в часовій області. Результати моделювання показали, що представлений метод має невелику розбіжність із відомими електродинамічними методами аналізу мікрохвильових пристроїв. Тому, розроблений новий хвилевідний поляризаційний пристрій з трьома діафрагмами представляє узгоджені та якісні електромагнітні характеристики у всьому робочому діапазоні частот 13,0–14,4 ГГц. Розроблений поляризаційний пристрій може використовуватися у антенних системах, де здійснюється поляризаційна обробка сигналів

Authors: Kolomiyets V. , Kachan O. 
Published: June 2021

Objective. To investigate the influence of the optic-reflex method of accommodation training on the indices of the meridional separable visual acuity in the treatment of children with amblyopia and astigmatism.
Material and methods. 24 children aged 5 to 12 years with refractive amblyopia and direct hyperopic astigmatism were examined. Accommodation training was performed by defocusing the image with optical glasses of variable optical power. The course of treatment lasted 10 days.
Results. In the group with meridional amblyopia, 2 different clusters were identified: in one of them, the indicators of separable visual acuity were higher in the horizontal meridian and in the other - in the vertical. After treatment, the number of eyes with the same meridional visual acuity increased. Simultaneously with the elimination of the meridional asymmetry of visual acuity, the number of eyes in the category of patients with visual acuity of 0.75-0.8 according to the Sivtsev table increased by 8.52%.
Conclusion. In the standard of assessment of visual functions in patients with astigmatism and amblyopia, it is necessary to introduce methods for determining the meridional visual acuity. Evaluation of the effectiveness of treatment of meridional amblyopia should be carried out in homogeneous clusters, which take into account the coincidence or discrepancy of the directions of meridional asymmetries of visual acuity with refractive. Preliminary data on the effectiveness of treatment of amblyopia by the method of accommodation training allows us to consider it as a method of treatment of meridional amblyopia.

The purpose of the study is to reveal the possibilities of introducing mobile applications in the process of teaching mathematical disciplines to future mathematics teachers. Research methods. Theoretical (analysis, systematization and generalization of pedagogical and psychological research, curricula for future teachers of mathematics) and empirical (pedagogical observation of the educational process, questionnaires) methods. Results of the research. By mobile learning we mean the process of creating a mobile educational environment with the use of mobile technologies for access to educational resources, implemented in face-to-face and distance forms. Active use of mobile educational applications leads to changes in the content of education, learning technology and in the relations between the participants of the educational process, allows to individualize learning, make it more adequate to the abilities of students. According to the survey results, the least attention in the study of mathematical disciplines is paid to applied mobile applications for mathematical calculations, but specialized programs and applications installed on mobile devices make them real assistants to teachers of mathematical disciplines and students of mathematical specialties. Our survey shows that the mobile application PhotoMath is the most popular among students when studying mathematical disciplines. We analyzed the possibilities of using the mobile application PhotoMath in the study of mathematical analysis by students of pedagogical universities.

Authors: Humeniuk Iryna 
Published: June 2021

The article considers the problem of effective construction of the working programme as the main kind of the educational and methodical support for a course. The relevance of the topic of the research is caused by the existence of significant differences between the evaluation criteria and the expected results of teaching, the content of the course and the requirements of the educational programme. The quality of the architectonics and contentual logic of a working programme illustrates the professional competence of the scientific and pedagogical worker. The aim of the article is to raise the awareness of the methodical problem of construction of the working programme of the Ukrainian Language for Professional Purposes course on the basis of the competence approach. The research process was based on the systemic structural and comparative methods of analysis of methodical materials, as well as generalisation and systematisation of the detected disadvantages. The selection of the working programme s for the analysis has been conducted considering the geographical criterion of the location of the pedagogical institution of higher education and the criterion of the free access to the educational programmes of the specialities 012 Pre-School Education, 013 Primary Education and the corresponding working programme s in the Ukrainian Language for Professional Purposes course. The results of the research have been formulated according to the determined parameters. A gradual decrease in the interest in teaching the course at pedagogical institutions of higher education has been indicated, as well as its replacement with the Bases of Academic Writing course at non-pedagogical institutions of higher education. The author emphasizes the non-systemic use of the competence approach, the absence of a clear correlation between the programmatic competences and their concretisation within the course. Clearly determined teaching results concerning each topic in accordance with the educational programme have not been detected in any of the analysed programmes.

Published: June 2021

The article presents the cognitive categorization principles in different ritual and non-ritual situations. The semantics, structure and pragmatics of omens as well as that of the related cultural concepts in the archetypal world model is based on ethnosemiotic and cognitive analysis aspects, folklore pragmatics elements and the cultural text verbal magic. The omens realize such significant for folk culture oppositions as good-evil, life-death, top-bottom, male-female, etc., as well as the connection with various traditional culture codes – action, ?bject, zoomorphic, artifactual, sociomorphic, verbal and so on. As a holistic cultural and cognitive macrosign, taken in the unity of functions, conceptospheres and semantic oppositions, the omen is organized according to the principle of situation-event cognitive cluster – action – reaction, forecast – belay, embodied in profiling a cultural prescription or taboo. As a cultural and folklore genre, the omens are based on the collective experience and are fixed in the collective memory as a correlation of two situations (events) that are in causal connection (predictive – predictable) fixed by folk tradition. The main attention is paid to the pragmatic and axiological properties of the omens, epistemological and ontological principles of their organization in the compared Slavic and non-Slavic linguistic (English) cultures.
Associative Identification of Proper Names: A Cognitive Approach
Authors: ALEKSIEIEVA Natalia 
Published: June 2021

Mental lexicon is a storage which holds the data about everything we know until it is required to be used. Onyms are stored in the mental lexicon in the form of concepts as individual units of knowlegde which reflect personal experience of the human being. The goal of the research is to explore the common ways of associative comprehension of proper names in order to better understand their essence and meanings they exhibit. The view is substantiated that transition from traditional to cognitive onomastic research will help to settle disputes among onomasticians and language philosophers as to the controversial subject of semantic and referential status of proper names.
The study is carried out on the material of the English official horse names as they are considered to be one of the proper name classes with the highest degree of arbitrariness of nomination. In this research, the author conducts a free associative experiment with 250 English native speakers. As the experimental material 5 stimuli of official hipponyms were chosen as well as the results of a free associative experiment of total quantity of 1136 reactions. The result of the study was the conclusion that the ways of associative identification of onyms depend not only on our presuppositional knowledge, direct or indirect experience in connection to a certain proper name, but also on a set of proprial and linguistic features peculiar to each name. The specificity of each proper name in this sense will determine the main mechanism of its associative identification.
Measure of departure from average marginal homogeneity for the analysis of collapsed ordinal square contingency tables
Authors: Aizawa Mana , Yamamoto Kouji , Tomizawa Sadao 
Published: June 2021

Summary
In clinical research, collected data are often classified into ordered categories using a set threshold to evaluate efficacy and safety of treatment. Data can be summarized as a shift table, which displays the change in the frequency of subjects across specified categories from the baseline to post-baseline. Although ordered categories are sometimes recombined into three categories, the combined patterns vary. To consider various collapsed patterns comprehensively, this paper proposes a new measure that represents the degree of departure from average marginal homogeneity, and can distinguish between two kinds of marginal inhomogeneity. Additionally, applications of the proposed measure to clinical data are discussed.
The Cost of Capital for Investment in the Warsaw Stock Exchange Indexes – Versus Djia
Authors: Urbański Stanisław 
Published: June 2021

Abstract

Research background and purpose: The CAPM, Fama-French and modified Fama-French models were used to estimate the cost of the capital of the DJIA and selected Polish stock indexes were used. The estimated cost of capital was the cost of the portfolio of corporate investment projects estimated by market returns.

Research methodology: The model tests were run on 276 monthly returns of stocks listed on the markets in the years 1995–2019. The bootstrap method to estimate the confidence interval of the cost of capital was used.

Results: The highest and positive cost of capital median was found for the DJIA index, about 0.85% monthly, and for the WIG20 and WIGDIV indexes, about 0.25% monthly. The cost of capital median for the mWIG80, WIGBANK and WIGCHEMIA indexes were found to be negative. This was due to large errors in the estimated cost of capital.

Novelty: Minor errors in the estimation of the cost of capital of index DJIA may result from a more rational policy for the implementation of investment projects by companies included in the index.
First Record of Ascosphaera apis Isolated from Commercial Pollen from Northern Argentinian Provinces
Authors: Tejerina Marcos R. , Benitez-Ahrendts Marcelo R. 
Published: June 2021

Abstract
In recent years, increased deforestation and replacement of areas intended for intensive cultivation have caused pathogens and parasites of Apis mellifera bees to emerge in regions where they had not previously been reported. Such is the case of the advancement of Ascosphaera apis, a fungus that causes a drop in colonies’ bee larvae population and great economic losses to beekeeping activity during severe cases. In northern Argentina, few studies have focused on this important entomopathogen. This is the first study on A. apis isolated from commercial pollen in Entre Ríos, Jujuy, and Misiones provinces, where its prevalence in bee colonies has not been reported. We identified this entomopathogen using macroscopic, microscopic, and molecular analyses, focusing on its botanical origin as a possible transmission route. We found the pathogenicity of each strain in A. mellifera bees to below 30%. The results of this study contribute to the promotion of sanitary measures that may reduce this disease’s progression in local apiaries.

Published: June 2021

Abstract
In recent years, interest in herbal essential oil extracts for the treatment of nosemosis has steadily increased. The great importance of this study is in evaluating and validating the synergistic effect caused by the mixture of different herbal extracts. The aim of the study was to investigate through cage experiments and field studies the effect of mixed herbal essential oil extracts and to determine the most suitable application methods and doses of the product in the treatment of nosemosis. The duration of the experiments was three weeks. Results show that the herbal essential oil extract mixture (HEOEM) is effective on both Nosema apis and Nosema ceranae, and on the two together (mixed infection). With respect to application methods, the results revealed that the most suitable method is spraying HEOEM with sterilized distilled water on adult bees and on both sides of frames; 500 µL per cage and 2,000 µL per frame were found to be effective doses of HEOEM in the experimental cages and hives. HEOEM can be a viable alternative to synthetic products in the immediate future as the contents are natural and have no toxic effect on honey bees.

The paper is aimed at measuring innovation and qualification of technological operations in automotive production within the quality management system. Quality requirements according to ISO/TS 16949 promote a process approach for the design and development, production, installation and servicing of automotive products, which can result in increased quality, reduced variation and increase of efficiency. The solution focuses on the process of approval of parts in series production (Production Part Approval Process – PPAP). The PPAP purpose is to determine whether an organization properly understood all customer requirements listed in the specifications and records of the technical design of the product. PPAP further verifies that the process has the potential to produce a product in series production so that customer requirements will be met, in actual production volume and at the agreed rate of production. Specifically, a toothed winch of hydroelectric generator is solved by the case study.
The Parody Mass and the Rethorical-Pedagogical Principle of Imitation
Authors: Marisi Rossella 
Published: June 2021

Abstract
In the sixteenth century, composing a parody Mass was a means to pay tribute to an admired piece and master the composing techniques shown therein. The parody Mass is grounded on the principles of imitation and emulation, on which the whole Renaissance rhetoric is based. This article analyses the Missa Quem dicunt homines by Palestrina. It stresses that in the Renaissance a musician could choose to compose a parody Mass, instead of a Mass on cantus firmus, not only to go towards the taste of his clients, and to suit his own preferences, but also to adhere to a certain rhetorical-pedagogical school of thought.
9. The Romantic German Lied – An Overview
Authors: Ursachi Doina Dimitriu 
Published: June 2021

AbstractThe lied represents a fundamental form of expression of the cantability and of the relation of the melody with the poetic. And, although the model of the cultural lied could still be heard in the music of the 18th century in the compositions of the Viennese classical school - in Haydn folk songs and, especially, in forms somewhat akin to the aria of Mozart or Beethoven – the landmarks of this genre were established precisely by the romantics of the 19th century, representatives in most of the German school. Schubert, Schumann, Franz, Mendelssohn-Bartholdy, Wagner, Brahms, Wolf etc. transformed the song into a cultural art form, incorporating images of popular origin into literary-musical structures for voice and piano making use of technical possibilities and expressiveness specific to romanticism.

The interpretative visions of Daniel Barenboim and Evgeny Kissin are equally interesting, the two great pianists putting their personality, sensitivity, and culture mark. All these elements confer upon the piece “32 Variations on an Original Theme in C minor” particular expressive valences highlighting Beethoven’s creative genius.
11. Five Lieder for Medium Voice and Piano, Op. 1 by Mihail Jora – Stylistic-Interpretive Considerations
Authors: Petrescu Cezara Florentina 
Published: June 2021

Abstract
Mihail Jora, „the father” of modern Romanian lied, consistently composed vocal miniatures for voice and piano between 1914 and 1968, permanently refining the appearance and content of this group of works that became representative for Romanian music. He began his journey in the first decades of the XX-th century, when, in Romania, the vocal-chamber musical genre had just begun its rapid evolution and synchronization with European trends, creatively capitalizing on the influence of already established composers. The visible transformation took place not only through the creative assimilation of formal patterns and the way music was „made”, but also trough the choice of poems. Five lieder for medium voice and piano [Fünf Lieder für eine Mittelstimme] op.1 on german lyrics is the work we will submit to stylistic-interpretive analysis to show both its uniqueness and its contact surfaces with the German lied and with Jora’s mature creation.
15. Aspects of Musical Language of Heitor Villa-Lobos’ Concert Studies
Authors: Dragomirescu Daniel 
Published: June 2021

Abstract
Careful research has shown that the Brazilian composer’s works are inaccurate in terms of indications yet respecting every parameter of music. Regarding the technical aspects, which represent the quintessence in the interpretation of string instruments, and in our case, a dark realm due to the lack of their representation on the score, the performer must make balanced decisions based on imagination and education acquired during years of study.
