Authors: Shevchenko Anastasiia , Lobova Olga
Published: January 2020

The importance of the development of individual’s general culture as a factor of his / her harmonious education stipulates the relevance of the study.
The purpose of the article is to describe the methods enabling the formation of teen-agers’ vocal and jazz culture at classes on pop singing (in musical schools and during extra-class activities in institutions of general secondary education). Methods of systematization and generalization of scientific sources, theoretical modelling, pedagogical experiment and so on have been used to achieve this goal.
The scientific approaches (systemic-structural, personality-developmental, activity-oriented, competence-based, cultural ones) and didactic principles facilitating the formation of the vocal and jazz culture (the principles of systematicity, visual aids, unity of artistic-emotional, technical and complex development of the vocal and jazz culture) have been determined.
The stages (motivational-stimulating, cognitive-developmental, performing-creative) as well as pedagogical conditions for the formation of the teen-agers’ vocal and jazz culture have been outlined: construction of educational process taking into account the children’s capabilities to perceive vocal and jazz music; systematic complex development of all the components of the vocal and jazz culture consistently emphasizing them at different stages of the training; giving the opportunities for vocal and creative self-realization, diversification of the experience of jazz musical performing activities.
General vocal and pedagogical methods have been revealed to be the leading ones (concentric, search-oriented, phonetic, imaginary or internal singing methods, comparative analysis); special methods enabling the formation of the teen-agers’ vocal and jazz culture have been determined: “a listening-jazz collecting box”, technical vocal and jazz exercises, creative vocal and jazz drills, etc.
The experimental verification of the developed methodology has proved its effectiveness at classes on singing variety music at establishments of general secondary education.
Keywords: teen-agers’ vocal and jazz culture, developing methods, scientific approaches and didactic principles, stages, pedagogical conditions and methods, classes on vocal and jazz singing.

Authors: Knyazheva Iryna
Published: January 2020

The improvement of the quality of preschool education is an important task for the modern stage demonstrating the development of the Ukrainian society, the implementation of which, above all, requires the efforts of higher education institutions to train a methodologically competent specialist, who is able to master and create innovative methods, techniques and technologies for organizing the educational process of a pre-school education institution. This task fully meets the requirements of the State Standard for Preschool Education in Ukraine, the documents regulating the functioning and modern guidelines for the development of pre-school and higher education of Ukraine in the 21st century. Under these conditions, the formation of methodological competence of the future pre-school educators is of paramount importance. The purpose of the article is to cover and analyse the results of the diagnostics determining the proficiency markers of the future pre-school educators’ methodological competence at the ascertaining stage of the experiment. We consider the methodological competence of future pre-school educators as an integrative personal composition characterized by these features: the presence of the ability to reflect, the desire to carry out methodological activities, the understanding of its value, theoretical knowledge and practical skills, which provide the ability to consciously and methodologically use methods and techniques and technologies of preschool children’s education, upbringing and development.
The structure of the future preschool educators’ methodological competence is made up of the cognitive, motivation- and value-centred, activity-oriented and evaluative-reflexive components and their indicators, according to which the manual of diagnostic methods is created and selected. During the ascertaining stage of the experiment, a sufficient level of methodological competence was demonstrated by 16.6%, a basic level – by 61.7%, a low level – by 21.7% of the future educators.
Keywords: future educators of pre-school education establishments, methodological competence, diagnostics, components, indicators, the ascertaining stage.
The essence and structure of creative abilities demonstrated by the future qualified workers in the sphere of services
Authors: Kushnirenko Alona
Published: January 2020

The main task of professional education today is not to master a set of knowledge, but to develop the creative thinking of future qualified workers, their skills and abilities in performing independent search, analysis and evaluation of information. Self-actualization, self-affirmation and realization of creative abilities are also of great importance. Developing creative abilities is a way to motivate students in their learning.
We live in the age of the scientific and technological revolution, and our life in all its manifestations becomes more diverse and more difficult at the same time, it does not require outdated or usual actions, on the contrary, it demands the mobility of thinking, rapid orientation, and a creative approach for solving big and small tasks.
Nowadays, taking into account the dynamic development of industry and services, the competitiveness of future qualified workers in the service sector depends not only on their acquisition of a high level of knowledge of the technological process and manufacturing tasks, but also on their ability to solve communication and compositional problems.
The purpose of the article is to determine the essence and structure of creative abilities of the future qualified workers representing the service sector.
On the basis of the theoretical analysis of psychological and pedagogical literature, we offer our own interpretation of the creative abilities demonstrated by the future qualified workers of the services sector; creative abilities are associated with person’s integrated, dynamic qualities and properties which manifest themselves in developing essentially new ideas, in creating something qualitatively new in the services sector.
Disclosing the structure of the creative abilities demonstrated by the future qualified workers of the services sector, we defined the following basic concepts for our research like: “services sector”, “a qualified worker”, “interactive technologies”.
Having processed the regulatory-legal documents of professional (vocational) education, we have identified the component structure of the creative abilities demonstrated by the future qualified workers of the services sphere by means of interactive technologies: the stimulating-motivating, intellectual-heuristic, personality-targeted and constructive components.
Different scientists’ approaches to the defining of the concept “abilities” and “creative abilities”, as well as the essence and structure of the creative abilities demonstrated by the future qualified workers in the services sphere by means of interactive technologies are considered in this article.
Keywords: abilities, creative abilities, creativity, sphere of services, a qualified worker.

Authors: Shchekotylina Natalia
Published: January 2020

The article deals with the problem of training future Physical Culture teachers to work within an inclusive education environment.
The purpose of the study is to describe the specificity of training future Physical Culture teachers to work individually with schoolchildren within the inclusive environment of the general educational institution; to substantiate scientifically and develop a model facilitating the training of the future Physical Culture teachers in individual work with schoolchildren under conditions of inclusion. The research was carried out using the scientific methods as follows: theoretical (analysis and systematization of information from scientific sources; content analysis of training programs aimed at future Physical Culture teachers in higher education institutions; pedagogical modelling); empirical (specially designed questionnaires, validity test methods developed by the author).
The author presents a three-stage (information-orientated, motivation-actualizing and practical-modelling) model of training future Physical Culture teachers in individual work with schoolchildren under conditions of inclusion, the pedagogical conditions for training future Physical Culture teachers in individual work with schoolchildren under conditions of inclusion being the core of the model (reflection of the essence of the phenomenon “inclusion” in the content of comprehensive disciplines; concentration of schoolchildren’s research attention on the health-saving segment of the individual work with schoolchildren under conditions of inclusion; involvement of future Physical Culture teachers to develop variable models of individual work with schoolchildren under conditions of inclusion).
The efficiency of the implementation of the designated model has been proved. Some positive shifts in the levels of the students’ readiness for individual work with schoolchildren under conditions of inclusion were recorded. Let us specify them: the optimal (high) level was demonstrated by 13% of the students (at the ascertaining stage ‒ by 10.3%), the basic (satisfactory) level was demonstrated by 57.6% of the respondents (at the ascertainment stage – by 11.8%), the elementary (low) level was characteristic of only 29.4% of the future teachers of Physical Culture (prior to 77.9%).

Theoretical bases for training future political scientists in profession-oriented activity in English
Authors: Kordonova Alla
Published: January 2020

Nowadays political reality is characterized by instability, the tendency of traditional state structures to collapse and the emergence of new interstate associations. The analysis of current political events taking place in them belongs to the professional activities of political scientists. As it is impossible to find a modern country which could develop beyond the formation of world civilization, there is no doubt that political scientists of different nationalities should communicate in the global English language.
It follows from the above that it is necessary to train qualified specialists in this field of knowledge who could fulfil their professional duties by means of English.
However, the existing methods of teaching English-language professional speech to the future political scientists do not provide students with the mentioned skills.
In this regard, the purpose of the suggested article is to work out theoretical bases for training future political scientists in profession-oriented activity in English.
The development of the above-mentioned skills is possible on the basis of the procedural integration of the English language and political science, where the links of these two different subjects are coordinated. A specific feature of the procedural integration is the manifestation of educational and professional foreign language skills alongside with foreign language professional skills in the profession-centred (field-centred) process. Thus, it is necessary to develop two integrated competences: the professional and foreign language speaking ones. For their development, the professional subject of the course of political science and the corresponding vocabulary necessary for the expression of its content have been determined. Integrated training of future political scientists in analysing current events in English includes the stages as follows: familiarization, language-oriented, training in speaking, and profession-centred.
Keywords: professional activity, integrated training, future political scientists, procedural integration, professional competence, foreign language speech competence.

Overcoming the stage-psychological barrier in the process of training masters in vocal
Authors: Koehn Natalya , Shiling Сui
Published: January 2020

The article deals with the problem of future vocal teachers training in performance activity. The author has focused on the psychological readiness for public performance, which is subjectively perceived as a stressful situation requiring psychological, emotional strain, maximum concentration of attention and volitional effort. A significant role of the psychological state for the singer caused by his/her reflection on the phonation-singing aspects; the degree of emotional brightness, artistic perfection in the creation of musical images has been specified.
The author has analysed the works of musical psychologists and representatives of theatrical and musical arts in relation to the factors of the performers’ unsatisfactory psychological state. Some features of productive and creative as well as excessive unproductive unrest alongside with its causes have been described. Three groups of determinants of the future professional’s personal psychological state have been considered: functional; motivational-characterological and operational. A special attention was paid to the types of the future vocal coaches’ performance activity such as performances in the form of academic reporting, contests, concerts and other educational events, pedagogical-illustrative methods as well as students’ entertainment. The participation in these activities is significantly different in the extent of responsibility for the performance quality and its possible consequences.
It has been pointed out how significant it is to choose the repertoire for the performance in accordance with vocalist’s real abilities, to hold auto trainings, to create «situations of success», role play and vocal-improvisation games in order to improve students’ performing-psychological state.
Keywords: vocal performance; future vocal teacher (coach); stage-psychological barriers, training, master students, stage-performing activity.
Ontopsychological aspects of artistic communication in the context of paradigmal changes within the system of modern art education
Authors: Alla Zaytseva , Alla Kozyr
Published: January 2020

The article is devoted to the problem of improving the quality of the training aimed at future teachers of Art disciplines in the context of paradigmatic changes within the system of modern art education. Based on the methods of theoretical analysis, generalization and abstraction, the state of research of the scientific problem has been clarified; the viewpoints of some researchers in this regard have been determined and connected with the ontological content of artistic communication. There have been considered scientific conceptual directions for defining the essence of the “artistic communication” and “ontological aspects of being” phenomena in the context of: philosophical concepts (M. Bakhtin, M. Buber, M. Kahan, V. Frankl et al.), ontological conditions of communication in the hermeneutic paradigm (H.-G. Gadamer, P. Ricœur); ontological ideas of the philosophers-existentialists, representatives of humanistic psychology (A. Maslow, K. Rogers, R. May), theoretical concepts of the ontological dimension of the “being” intended for the subjects of the artistic and educational process (N. Huralniuk, O. Yeremenko, O. Mykhailychenko, O. Oleksiuk, V. Orlov, G. Padalka, O. Rebrova, O. Rudnytska, V. Fedoryshyn, O. Shcholokova et al). The synthesis method enabled us to make a deliberate formulation of the author’s definition. The phenomenology of communication in the artistic and educational projection as a vector of humanistic orientation of the subjects of interaction with an art to the awareness and correction of their own subjective development has been presented. The author emphasizes the implementation of the existence-centred and reflexive approach, which makes it possible to achieve coherence between ontological positions of the teacher and the student in the process of communicating with arts. The author’s position, according to which communication is determined by the deep onto-psychological connection between two individuals oriented to meeting the other type of existence and involves the achievement of a spiritual unity between them in the joint work, has been grounded.
Keywords: higher Art education, future teacher of Music, the existence-centred and reflexive approach, onto-psychological aspects, values, meanings, artistic communication.

The General election or in other terms called Election is an absolute requirement to carry out people's sovereignty for a democratic country and to establish itself as a democratic state. An election is used to be democratic or not, depends on the existence of an election organizing body or institution. In order to realize quality and capacity elections, professional electoral institutions are also needed. However, this will be difficult to realize if the electoral institutions itself, between the General Election Commission (KPU), the Election Supervisory Body (Bawaslu) and the Election Administrators Honorary Council (DKPP) are having differences in opinion continually. This difference in opinion occurs because of the lack of clarity regarding the mechanism of organizing the election in the general election organs so that the regulation must be corrected and explicitly clarified about the authority and responsibility of each general election organ. This research uses normative laws by the laws of the election approaches. The purpose of this research as a critic between KPU, Bawaslu, and DKPP to carry out their authority by clarifying the mechanism of election management. With the explanation above, the author concludes that, between the KPU, Bawaslu and DKPP have to clarify their respective authority and responsibilities, so it isn’t to be a cause in differences opinion which would result in undemocratic elections.

Published: January 2020

This paper assessed in-vehicle and ambient pollution levels from vehicles along Ilorin-Lagos highway covering three distinct 3-hour periods (morning, afternoon and evening) of the day (from 7.30 am to 6.30 pm) along with reported health challenges at six (6) settlements (SP1-SP6) that covered four (4) states. In the case of ambient pollution, Gilair-3 air sampler (GAS) was used to measure sulphur (iv) oxide, (SO2) while ALTAIR 5x Multi-gas Detector (AMD) was used to measure both carbon (ii) oxide, (CO) and sulphur (iv) oxide, (SO2) for all scenarios. Vehicular volume was manually conducted to determine the number of vehicles. Questionnaire was used to assess information on the health challenges faced by the commuters. The concentrations of SO2 ranged from 0.142 - 0.550 ppm (ambient) and 0.037 - 0.097 ppm (in vehicle) using AMD and GAS respectively while CO concentration was between 2.289 - 18.055 ppm using AMD. The results for the in- vehicular pollution revealed that the concentration levels obtained for CO and SO2 inside the vehicles were 6.32 ppm and 0.126 ppm under opened-window condition and 9.53 ppm and 0.274 ppm under closed-window condition respectively (without air condition). The SO2 concentrations obtained from both ambient and in-vehicle were found to be much higher when compared with the FEPA standards; SO2 (0.01 – 0.1 ppm), USEPA standards; SO2 (0.075 ppm) while the CO level obtained from in-vehicle under the two scenarios (opened and closed windows) were below the limit of NESREA standards (10 – 20 ppm) and USEPA standards (35 ppm). Having noticed that these pollutants act under different environmental conditions, the work established statistical evidence that traffic volume affected the pollutants concentrations at most of the sampling points and that the higher the traffic, the higher the emissions and the more the risk of health challenges.

Exopolysaccharides (EPS) is a type of polysaccharide produced by lactic acid bacteria (LAB) that can be directly used in foods to make the products more excellent. Therefore, batch studies were performed to explore the effect of different LAB on the production of EPS and antioxidant activity. Five strains with high EPS yield and antioxidant activity were screened out from 66 strains isolated from Tibetan dairy products. The results show that EPS produntion of the five strains (B55, B62, B30, 7830 and K2) were 110.66, 145.48, 132.78, 122.11 and 111.72 mg·L−1, respectively, and they have a higher DPPH free radical scavenging activity (56.29, 66.43, 62.94, 68.71, 61.87%). Five LAB strains were identified and classified based on screening, purification and 16S rDNA sequences. Molecular characterization based on partial sequence 16S rDNA homology confirmed the initial identification as Lactobacillus fermentum (B55, B62), Lactobacillus plantarum (7830), Pediococcus acidilactici (B30) and Lactobacillus helveticus (K2).

Biosurfactant attracts people’s attention because of its advantages of green and low toxicity. Lactic acid bacteria are beneficial to human and animal health. In order to make the application of surfactants safer, SDS standard curve was established, 65 strains of Lactic acid bacteria were used as screening source, and oil expanding circle was used as index to screen the strain with strong surfactant production capacity. The results showed that the standard curve of SDS was Y=34.82+(-1495.97) X1+33.11X2, and all strains had the ability to produce surfactants. Surface activity varied with bacteria. The concentration of surface activity ranged from 111.15mg/L to 736.23 mg/L. The concentration of BS in supernatant of LB6, 49, F70, 20 and Y1 strains was selected for screening. The concentration of BS in supernatant was 561.01~935.77 mg/L, and the concentration of BS on cell surface was 401.67~1076.94 mg/L. Considering the highest BS-producing strain is F70, the result of 16SrDNA showed that the strain is Pediococcus acidilactici F70. This experiment provides basic data for the production of surfactants by Lactic acid bacteria.

Authors: Chełpiński Piotr , Ochmian Ireneusz , Forczmański Paweł
Published: January 2020

Colour measurement is one of the methods used to evaluate food quality. Aim of completed research was the evaluation of a fast and non-destructive method which consisted of assessing colour changes. It was used to determine the ripeness of cherries during their harvest. Additionally, the most significant parameter determining fruit ripeness was identified. Colour measurements of the Burlat cherry on the PHL A rootstocks were supposed to provide standards for practical evaluation of fruit ripeness of this species at an orchard. During the research, the measurements concerned the internal quality of the cherry fruit (firmness, extract content) and the force required to tear off the stem, depending on the size of the fruit. The extract appeared to be the most important indicator to be used for the determination of an optimum harvesting period. It was most prominently correlated with the cherry’s colour. Changes in the skin colour were the most reflected by the value of the parameter CIE a*. The coordinates CIE L* and b* are also important for the determination of fruit quality. Burlat cherries achieve their optimum harvesting ripeness if the coordinate a* is within the range 30.0 to 0.0, the coordinate b* within 10.0 to 0.0 and the coordinate L* within 30.0 to 20.0, which corresponds to the extract value of 12-20%.

In the context of demographically ageing communities across rural Europe Smart Villages have considerable potential to promote ageing healthy. Whilst in principle supporting healthy ageing in the context of the Smart Village might appear a relatively straightforward endeavour, in operational terms, successful development of smart, 21st century villages relies upon, and sometimes assumes, an appropriate interplay of socio-technological factors. Articulated through a lens provided by the digital ecosystem model advocated by the European Network for Rural Development (2018), this paper offers some observations from the field. We acknowledge the challenges faced by remote rural places in their journey to become ‘smart places’ and identify formal and informal interventions that could better position rural communities to become part of a wider, smart society.
Delivering on the Concept of Smart Villages – in Search of an Enabling Theory
Authors: Slee Bill
Published: January 2020

Smart villages have been increasingly heralded as a development strategy for the European countryside but with no clear understanding as to what comprises a smart village. Frequently, commentators associate smartness with quality of IT infrastructure and the ability to use it. An alternative perspective argues that the smartness can be better understood as a phenomenon associated with self-organised, bottom-up community action that either addresses the weaknesses of both state and market to contribute to local people’s wellbeing or exploits emergent opportunities through collective means. Using Scotland as an example, policy architectures can now be seen to be explicitly designed to support bottom-up community action. This paper explores this alternative notion of smartness based on communities’ capacities to self-organise and deliver a range of developments that support wellbeing and resilience and explores some of the challenges arising from this approach.
Determination of Pleurotus abieticola ligninolytic activity on Norway spruce wood

The effect of Phlebiopsis gigantea treatment in control of Heterobasidion parviporum in Norway spruce is less effective than that in control of Heterobasidion annosum in pine. It is necessary to apply other fungi, for example, Pleurotus abieticola in Norway spruce stands. Thus, it is necessary to assess the activity of major ligninolytic enzymes, that is, laccase, lignin peroxidase (LiP), manganese peroxidase (MnP) and versatile peroxidase (VP) produced by P. abieticola, which may be effective in the fast degradation of Norway spruce wood. Three strains of P. abieticola (Pa1-3) were grown on pieces of Norway spruce sapwood and heartwood for 50 days in laboratory conditions. Enzymatic activity was determined using spectrophotometry. Pleurotus abieticola produced laccase, LiP, MnP and VP. The activity of laccase was low, ranging 0–3.696 and 0–0.806 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 3.696 mU/μg of protein in sapwood and in Pa3 = 0.806 mU/μg of protein in heartwood was observed after 30 and 50 days of incubation, respectively. The activity of LiP was also low, ranging 0–0.188 and 0–0.271 mU/μg of protein in sapwood and heartwood, respectively. The highest activity in Pa1 = 0.271 mU/μg of protein in sapwood and in Pa2 = 0.188 mU/μg of protein in heartwood was observed after 40 and 20 days of incubation, respectively. The activity of MnP ranged 0–17.618 and 0–12.203 mU/μg of protein in sapwood and heartwood, respectively. This enzymatic activity peaked at the 50th day of culture on sapwood for the Pa3 strain (17.618 mU/μg of protein) and at the 20th day of culture on heartwood for the Pa1 strain (12.203 mU/μg of protein). The activity of VP with manganese-oxidising properties was found to be high in all strains of P. abieticola, ranging 0–39.19 and 0–59.153 mU/μg of protein in sapwood and heartwood, respectively, whereas the activity of VP with guaiacol-oxidising properties was very low for all P. abieticola strains, ranging 0–0.248 and 0–0.225 mU/μg of protein in sapwood and heartwood, respectively. The values of released hydroxyphenols in P. abieticola strains ranged 24.915–139.766 and 25.19–84.562 µg of protocatechuic acid/ml in sapwood and heartwood, respectively. The values of released methoxyphenols for the evaluated strains of P. abieticola ranged 7.225–23.789 and 1.953–20.651 µg of vanillic acid/ml in sapwood and heartwood, respectively. Further studies with a higher number of strains of this species as well as an optimisation of conditions for the measurement of ligninolytic activity are needed.
Up to Date in Internal Medicine: From Older to the New 2019 Systemic Lupus Erythematosus Classification Criteria

Systemic lupus erythematosus (SLE) is considered the prototype of autoimmune diseases, the most complex autoimmune pathology and it is characterized by a wide range of immune processes, important antibodies production as well as an impressive spectrum of clinical manifestations. The great variety of lupus signs and symptoms caused difficulties in establishing well-defined classification criteria, as well as sustaining the clinical diagnosis.

In 2019, a joint initiative of European League Against Rheumatism (EULAR) and American College of Rheumatology (ACR) released a new set of classification criteria for SLE, worldwide SLE experts were involved, this being the largest SLE classification effort up to date.
A Surprising Evolution of Myocardial Infarction in Young Adults

Introduction. Ischemic heart disease is the leading cause of death with increasing prevalence. Acute myocardial infarction is a consequence of prolonged acute myocardial ischemia, which appears secondary to an imbalance between oxygen consumption and intake at this level.

Case report. We present the case of a male patient, aged 53 years old, admitted in the Cardiovascular Recovery Clinic for moderate dyspnea, intermittent dizziness and muscle pain predominantly in the lower limbs. Regarding his medical history, he suffered an antero-lateral myocardial infarction due to excessive physical effort, which was trombolysed. Following the remission of the acute episode, the evolution over the next 6-12 months was towards heart failure clinically manifested by dyspnea. Considering the presence of heart failure associated with severely diminished ejection fraction, the medication is adjusted and Sacubitril/Valsartan is introduced at a dose of 49/51 mg twice a day, under which our patient presents with both clinical and echocardiography improvement. Cardio-pulmonary stress testing is the most accurate as it provides the best information regarding functional capabilities, beyond the ejection fraction of the left ventricle. Following the treatment with RNAi (angiotensin receptor-neprilysin inhibitor), the parameters evaluated during the stress test were improved, which is clinically transposed by improving the quality of life and implicitly the long-term prognosis.

Conclusion. The particularity of this case consists in the occurrence of myocardial infarction at a young age (36 years) in a patient without a heredocolateral history or associated risk factors at that time. The association of ARNI (Sacubitril / Valsartan) in the therapeutic scheme has determined a clinical improvement, as well as paraclinical especially regarding the echocardiographic parameters (the ejection fraction increased from 25% to 40% at the end of the evaluation).
