HISTORICAL PERIODS AND CURRENT STATE OF ADULT EDUCATION AND LEARNING IN UKRAINE
Authors: Лук'янова Лариса , Дернова Майа
Published: December 2021

Currently in Ukraine the relevance of adult education as an integral part of lifelong learn-ing is growing, which is associated with social, psychological, pedagogical, scientific, technical, economic and other factors that at the beginning of the XXI century transformed adult education from a purpose to a mean of human development. The article, based on a theoretical analysis of dissertation research and the legal framework for adult education and training, presents four historical periods of adult education development in Ukraine; characterizes its current state including the main structural components (further education, non-formal learning, continuing professional development and in-house training, training of the unemployed, education and training of the elderly), providers, management, legislative and financial support. A number of contradictions regarding the development of adult education and training in Ukraine have been identified. The study shows a steady interest of Ukrainian researchers and society in the problems of adult education and training and the formation of andragogy research school, as evidenced by the number of defended disser-tations on this issue, including 22 doctoral dissertations and 48 PhD theses. In addition, it has been found that more dissertations study adult education and training in foreign countries. At the same time many issues in adult education require immediate consideration, such as the adoption of the Law of Ukraine «On Adult Edu-cation», amendments to current legislation, development of mechanisms encouraging people to lifelong learning and employers’ participation in employee training, and investment attractiveness of adult education
UNESCO'S CONTRIBUTION TO TEACHER EDUCATION QUALITY ASSURANCE
Authors: Авшенюк Наталія
Published: December 2021

This article is based on an analysis of the leading UNESCO documents on quality assurance in teacher education (Teacher Policy Development Guide (2019), Reimagining our futures together – A new social contract for education (2021), The Futures of Teaching: Background paper prepared for the Futures of Education Initiative (2021)) focuses on the determinants for increasing the effectiveness of teachers' work. The reports also highlight the factors which make teachers more effective and satisfied in their work, create a positive attitude, increase motivation and improve pupils' success, as illustrated by the study of the education systems of various countries. They state that a comprehensive national policy for teachers backed by suffi-cient resources, the necessary political will and appropriate administrative skills is the most effective of all possible investments in education at the national level.The recommendations of the UNESCO International Task Force on Teachers for Education 2030 are reviewed. The UNESCO Teacher Policy Development Guide aims to foster professionalism and teaching excel-lence, including strategies for recruiting and training talented teachers. The Guide is intended to assist gov-ernmental institutions and structures responsible for education policy at the national level. The Guide aims to help educators and educational planners and policy-makers coordinate educational policies with national education sector plans and strategies. The Guide emphasises in particular that education policy should reflect the specifics of the country, but should also be based on the progressive experience of other countries and international organisations.
THINKING ABOUT THE FUTURE: PHILOSOPHY AND SCIENCE FICTION IN CLAIRE NORTH'S NOVEL "THE FIRST FIFTEEN LIVES OF HARRY AUGUST"
Authors: Fedosova M.
Published: December 2021

As developed in this paper, science fiction shows us the distorted vision of the present with its anxieties about (mis)use of science although it deals mostly with the future and alternative realities. Thus SF stories both praise scientific progress and repulse its terrible applications caused by irresponsible abuse of technology. This paper focuses on how contemporary SF deals with philosophical issues of life, death, technology, and the role of science in society. It reviews Claire North's novel "The First Fifteen Lives of Harry August" in which SF conventions parallel and intensify the thriller narrative. The philosophies of Nietzsche and Heidegger have been employed to discuss the theory of eternal return and related topics of nihilism, devaluation of values, and purpose of existence. It is stated that the novel reveals how cognition of totality may lead to death and illustrates that human beings are incapable of achieving omniscience. Personal time is measured by memory and is always linear; therefore it can guarantee meaningful existence only when its arrow points towards growth and maturity. It is shown that ethical issues raised in the novel are based on the distinction between theoretical science signifying truth and its practical application meaning power. Knowledge by itself lies beyond morality; however, means used in its pursuit entail responsibility to others.
Composition of English News Stories: Strategies or Schemas?
Authors: Potapenko S.
Published: December 2021

The research deals with the composition of the English news story revealing that it rests on the interaction of strategies, tactics and schemas of perceptual origin. The material of the research is the BBC news stories. The paper applies cognitive and discursive methods to revealing the composition of English news stories. The results obtained show that strategies determine the choice of predicates structuring an event. Schemas of perceptual origin define the representation of event components in terms of human perception of environment: focusing, with the concentration of attention on one entity; identification, with the introduction of a single entity into the reader’s visual field; zooming-in by the use of the nouns indicating a transformation of a far distance into remote, close or immediate. In this case remote event models are comparatively few in number, because they offer a general picture of what is happening, without going into detail. In case of the subjective zooming-in model the desired effect is evoked by the interaction of collective nouns pointing to a group, i.e. distant perspective, and units in the plural, implying a distant position. The event-subjective perspective is implemented by a sequence of uncountables, denoting a general state of affairs, countables in the plural and in the singular, representing participants from the near or close distance. The tactics include verbalized contents into the composition of the text introducing the sections of context, commentaries, referring to witnesses or sources of information. The conclusions indicate the interaction of strategies, perceptual schemas and tactics in organizing English news stories.

Published: December 2021

Background: Antibiotic resistance is considered to be the next worldwide epidemic. Urinary tract infections (UTI) are the second most common cause of infection, which also has the highest resistance frequency. Nevertheless, in high Andean regions, little is known about the antibiotic resistance. Objectives : Determine the antimicrobial resistance patterns of the enterobacteriaceae family isolated from urinary tract infections of a Peruvian Andean region. Material and Methods: A retrospective cross-sectional review of 1717 records from the microbiology service of a private health institution from Puno - Peru, was done between the years 2014 and 2017. Antibiotic resistance by uropathogens was studied among different age groups. Statistical analysis included Chi2 test with a p<0.05. Poisson regression was used to calculate the prevalence ratio (PR) with a 95% confidence interval. Findings: There was a wide distribution of antibiotic resistance among all the antibiotics, mainly in Escherichia coli and Proteus spp. The elderly had the highest prevalence of antibiotic resistance. As age increased, resistance to all drugs also increased (p<0.01). Furthermore, the elderly had a risk probability of resistance of 1.22, 1.42, 1.20 and 1.32 to penicillins, cephalosporins, quinolones and other antibiotics respectively. Conclusion: The antimicrobial resistance patterns of the Peruvian Andean region were lower than national and international patterns.

Aprendizaje Invertido: un enfoque para promover estrategias de autoaprendizaje en la adquisición del inglés como lengua extranjera
Authors:   , Pacheco Salazar Vicente Guillermo
Published: December 2021

El Aprendizaje Invertido (AI) es definido como un modelo que invierte las actividades de clases síncronas por las asíncronas, y viceversa, optimizando el tiempo de aprendizaje con el docente en el desarrollo de destrezas de orden superior. En la actualidad, investigación en el campo del AI, se ha llevado a cabo principalmente en la enseñanza de materias de contenido específico, tales como introducción a la música, matemática, ciencias sociales, humanidades, entre otras, y en menor grado en el ámbito de las lenguas. Por lo tanto, no se pueden derivar hallazgos concluyentes o generalizables sobre el modelo de AI, a nivel universitario, en la adquisición del inglés como lengua extranjera (EFL). El objetivo principal de este estudio fue analizar el impacto de la implementación del modelo de AI en la adquisición del inglés como lengua extranjera en el marco de la educación superior. Para ello, se utilizó un diseño de investigación explicativo secuencial de métodos mixtos, en el que participaron 389 estudiantes de EFL de tercer nivel (A2+) del Instituto de Lenguas y 45 docentes de EFL, de la Universidad de Cuenca. El proceso se desarrolló en dos fases con una duración de 5 meses cada una. La fase uno fue exploratoria y tuvo el objetivo de recolectar información respecto de los estilos de enseñanza y aprendizaje, respectivamente. La fase dos fue de ejecución y comprendió el pilotaje y la ejecución del modelo de AI. En términos generales, este estudio encontró que los estilos de aprendizaje son principalmente reflexivo y activo, mientras que los estilos de enseñanza se orientan hacia el estudiante principalmente en las características generales y manejo de la clase. El proceso de ejecución del AI consideró estas dos características para diseñar experiencias de AI con la plataforma Moodle. Los resultados muestran un avance promedio de 16, 14, 12 y 9 % en las destrezas de comprensión auditiva, comprensión lectora, producción oral y producción escrita, respectivamente. La percepción general de docentes y estudiantes es muy favorable respecto de la aplicación del modelo de AI para desarrollar habilidades y destrezas de la lengua extranjera. Conforme a los hallazgos y la literatura científica, se concluye que las habilidades receptivas son convenientes de desarrollarlas mediante autoaprendizaje, mientras que, las habilidades de orden superior requieren del apoyo del docente, por lo que es mejor desarrollarlas sincrónicamente.
Features of time variations of microseismic noise at seismic stations in Tajikistan
Authors: Zhuravlev Vladimir , Lukk Albert
Published: December 2021

The spectral structure of microseismic noise in the frequency range of 0.01-40 Hz at different times of the day and year, recorded by broadband equipment at eight IRIS group seismic stations in Tajikistan in 2005-2020, was analyzed. Two disjoint frequency ranges are distinguished, which we conditionally call "high-frequency" (2-40 Hz) and "low-frequency" (0.01-0.75 Hz) noise, separated by a natural drop in the noise amplitude to 20-30 Db. It is assumed that the high-frequency range of noise has a local nature, due to exogenous sources of natural origin in the form of wind gusts, concussions from powerful watercourses and fluctuations in the level of large reservoirs, as well as man-made in-terference due to road and quarry explosions, the work of large industrial enterprises and concussions from road traffic. Low-frequency noise is most likely caused by global storm microseisms. High-frequency noise has a well-defined daily frequency, which is completely absent in low-frequency noise. At the same time, in both frequency ranges, the existence of a clearly pronounced seasonal peri-odicity has been established, the amplitude of which reaches 6-7 Db for high-frequency noise and about half as much for low-frequency noise. However, at the same time, the seasonal frequency of high frequency and low-frequency noise turns out to be antiphase, which indicates in favor of the different genesis of these two components of microseismic noise. The amplitude of the diurnal periodicity in variations of the high-frequency noise level is maximal during the daytime, remaining approximately constant for 8-10 hours. At the same time, the decline in the noise amplitude in the evening lasts longer than the steeper morning growth. The time intervals of a sharp increase and decrease in the intensity of the discussed daily extreme are quite well correlated, respectively, with morning and evening twilight at different times of the year. This is reflected in the wider flat part of the maximum noise level in summer compared to winter and the differences in its level up to 6 Db in favor of summer time. This observation can be considered as a manifestation of the deep influence of the Sun on the oscillatory processes that generate high-frequency microseismic noise.

A novel adsorbent made of porous cellulose/graphene oxide composite microspheres (PCGCM) was synthesized in [Bmim]Cl ionic liquid. The as-prepared PCGCM was evaluated for the removal of Ce (III) via static adsorption experiments. The results showed that the adsorption equilibrium of Ce (III) onto PCGCM was achieved within 50 min and the adsorption was highly pH dependent. An excellent adsorption capacity as high as 415.1 mg•g-1 was obtained at a pH of 4.9, which was much higher than most adsorbents reported in the literature. The pseudo-second order kinetic model and Langmuir isotherm model were found to fit the adsorption behavior of PCGCM well. The XPS analysis confirmed that the adsorption was based on the ion exchange mechanism. Meanwhile, PCGCM could be regenerated with 1 mol•L-1 HCl for repetitious adsorption of Ce (III). This work provides an attractive approach for the removal of rare earth ions as pollutants.

High-value products can be obtained from non-traditional lignocellulosic resources, such as bamboo, taking full advantage of these materials through efficient, low-cost and low-pollution fractionation processes. This work aims to analyze the physical, chemical, and morphological differences between two bamboo species as a rapidly growing resource of great regional interest – Guadua trinii and Guadua angustifolia. Both samples were characterized in terms of basic density, morphological characteristics, and chemical composition. This work shows that G. trinii has a significantly denser woody structure, with a uniform density at the sampled culm height. The internal structure consists of a parenchyma matrix and vascular bundles composed of parenchyma cells and fiber bundles. G. angustifolia has significantly longer fibers. Chemical characterization showed differences between the carbohydrate and lignin contents. The results of this work are critical to know the potential of both bamboo species as a source of high-value products in the bamboo biorefinery framework.

Valorization of agricultural and agro-food by-products by fermentation constitutes a very interesting biotechnological approach for the production of lignocellulolytic enzymes. This work was carried out to reveal the effect of some lignocellulosic materials on the mycelial growth and lignocellulolytic enzymes production by Bjerkandera adusta BRFM 1916. The strain showed ABTS- and guaiacol-oxidation activities. The optimal temperature for mycelial growth was 28 °C. The maximum growth rate of this fungus was achieved on wheat bran (2.08 ± 0.05 cm day-1), followed by barley bran, with a significant reduction of 6.73%. Several agricultural lignocellulosic residues were used as substrates for enzymes production. All the data indicated differential utilization of the various materials by the fungus. The selected fungus produced good CMCase (690 ± 0.066 UL-1) and β-Glu (253 UL-1) activities on wheat bran and orange peels, respectively.

This study reports on the production, characterization, and application of a novel starch/graphene oxide nanocomposite for rapid synthesis of 2,4,5-trisubstituted imidazoles. To this end, graphene oxide was first functionalized by 1,8-diamino-3,5-dioxaoctane under appropriate conditions. Starch, functionalized graphene oxide, and 3-aminopyridine nanocomposite were then prepared from the reaction of starch with graphene oxide functionalized with 1,8-diamino-3,5-dioxaoctane in the presence of hexamethylene diisocyanate (HDMI) as a binding agent and 3-aminopyridine. Then, trifluoroacetic acid was added, giving rise to an acid-supported starch and graphene oxide nanocomposite. To examine the efficiency of the nanocomposite, 2,4,5-trisubstituted imidazoles were efficiently synthesized in the presence of the nanocomposite using benzil, aryl aldehyde, and ammonium acetate under solvent-free condition within a short reaction time. The moderate conditions, fast reaction rates, ease of purification, solvent-free condition, use of a green catalyst (nanocomposite), and environmental friendliness are among the advantages of the proposed synthesis method. The recoverability and durability of the catalyst were confirmed after five runs with no significant loss of activity. Thus, this research presents a novel nanocomposite based on starch and graphene oxide with superior properties.

Water hyacinth (Eichhornia crassipes) (WH) is an invasive plant floating freely on the water, which is widely spread in tropical and subtropical regions. The plant is characterized by high porosity and a high number of functional groups, such as hydroxyl (-OH), carboxyl (–COOH), and amino groups (–NH2). Activated carbon, which is widely accepted on an industrial level for the adsorption of dyes from wastewaters, is a highly expensive material. Thus, in this research, a bioadsorbent material was prepared based on WH biomass and investigated as an alternative tool for water quality remediation, in the case of dye pollutants (RR HE3B). The WH plants were collected from the nearby Lake Tana and used as an adsorbent material without chemical treatment. The batch adsorption test was performed by varying the pH of the solution, adsorbent dosage and initial dye concentration. The powdered WH and RR HE3B dye loaded WH were characterized using FTIR, revealing the emergence of new stretching vibration peaks in the range from 2800 to 3000 cm-1 on the spectrum of Reactive Red HE3B (RR HE3B) dye loaded WH, confirming that -CH and -CH2 were responsible for the adsorption. The analysis of the adsorption isotherm and of the suitability of different models for describing it has led to the following order: Freundlich > Langmuir > Temkin > Dubinin-Radushkevich, based on their correlation coefficient value. This implies that the WH adsorbent surface is heterogeneous and the adsorption of the dye onto it depends not only on the specific reaction sites, as the n-value of the Freundlich constant confirms that the physical adsorption process might be favored. Therefore, WH could be a potential alternative adsorbent to remove the RR HE3B dye from dye polluted wastewaters.

The main objective of this work has been to study the performance of membranes developed for water treatment. Polymeric membranes (CTP and CTP-Acid) were developed from solutions containing cellulose acetate (CA), cellulose triacetate (CTA) and polysulfone (PSF), using maleic acid (MA) and acetic acid (AA) as additives and chloroform/dioxane as solvent. The NIPS-type phase inversion method was chosen as the membrane film manufacturing technique. The incorporation of 2.5% and 5% by weight of acids in the membrane mixture allowed us to study the additive effect on the morphological structure, and to predict the performance of the membranes formed. The characterization of the membranes was performed by SEM and FTIR analyses. Examining the flux, permeability and selectivity of the membranes also permitted to study the efficiency and performance of each membrane. The addition of AA and MA additives within the mixture increased the hydrophilic character and improved the flux rate by increasing it from 75 Lm-2h-1 to 142.74 Lm-2h-1 for 5% maleic acid addition. The 5% CTP AA membrane gave very satisfactory results in terms of selectivity, with a maximum removal of 84% of NaCl salt. Therefore, this membrane has been considered to be the most efficient one, with a flux of 120 Lm-2h-1 to 15 bar and a NaCl salt retention that meets the standards required by the World Health Organization (WHO).

Published: December 2021

The influence of laser fluences and scanning speeds on the morphologies of laser-induced periodic surface structures (LIPSS) on heated LiNbO3:Fe (1000 °C) was investigated under femtosecond (fs) laser scanning irradiation. Laser fluence of 8.5 kJ m−2 and scanning speed of 1 mm s−1 were found to be optimum process parameters, and large-area fs-LIPSS on LiNbO3:Fe with an area of 8 mm × 8 mm were fabricated with these parameters. The wettability of laser-textured LiNbO3:Fe changed to be hydrophilic, and the absorptance was improved substantially in the spectral range of 400–2000 nm. This technique is efficient, and environmentally friendly, which will attract tremendous interest in nano-photoelectron and nano-mechanics.
Basic investigation on identification of tissue composition based on propagation speeds of longitudinal and shear waves

The elastic modulus of tissue as a useful biomarker of disease detection can be quantitatively evaluated based on shear wave speed (SWS) measurements in shear wave elastography. Although the longitudinal wave speed (LWS) is also expected to be a promising biomarker for disease detection, the elasticity is not always dominant because the LWS is affected by the bulk modulus. In other words, LWS and SWS may reflect different tissue properties. Therefore, in this study, based on the improvement in LWS measurement, the relationship between the composition of a phantom mixed with agar and glycerol and ultrasonically measured LWS and SWS was investigated. The LWS had a good sensitivity in detecting glycerol, while the SWS had a good sensitivity in detecting agar. The calculated Poisson’s ratio had a better sensitivity in detecting agar. In conclusion, a simultaneous measurement of LWS and SWS may help identify the tissue composition.

Skills and qualifications mismatch phenomenon: focus on human capital in the global measurement
Authors: Kuznetsova Nataliya
Published: December 2021

The article examines the essence and significance of the phenomenon of mismatch in skills and qualifications as a generalizing concept that combines all types of gaps and imbalances in skills and qualifications. Different types of this mismatch are considered. The factors that determine the spread of this phenomenon have been identified. The danger of widening the gaps in qualifications and skills, which manifests itself in the negative impact on the formation of qualitative characteristics of human capital and causes inefficiency in the use of its potential is substantiated. Through the prism of human capital, potential threats and global challenges caused by skills mismatches and their implications for society, employers and employees have been identified. Based on the analysis of increasing mismatch in skills and qualifications of workers, the formation of current trends in the global labor market has been examined; and these trends are: the existence of the so-called "post-pandemic hiking workers freezing syndrome" as an imbalance between supply and demand for jobs provoked by the COVID-19 pandemic; deepening the mismatch between the level of working people education and the jobs they occupy, indicating a significant global gap between education and employment. Possible ways to overcome skills and qualifications mismatches include strengthening the role of employers in deciding this issue and using the Future Skills Architect practical set of instruments, where the key indicator is the country's maturity index (FSA), which will enable governments of countries to form sets of quality solutions in the struggle for human capital.
Methodological approach to assessing the effectiveness of organizational development of enterprise
Authors: Ralko Oleksandra
Published: December 2021

The organizational development concept has been developing since the 1930s. And there are two main trends: research and practice of laboratory training; analysis of the organization and feedback systems. The classical concepts and definitions of organizational development were based on the fact that the main way of organizational development professionals is to help organizations solve problems that hinder the efficient use of human resources; create an organizational environment that stimulates the development and self-improvement of the employee of the organization and achieve more successful and productive functioning of the organization as whole. Modern concepts of organizational development emphasize the maximum integration of individual needs and interests of employees, goals and objectives of the organization as whole, as well as the creation of structures, systems and processes that would provide continuous improvement of the organization. The set of characteristics developed by us for determining the state and evaluating the effectiveness of organizational development fully meets certain requirements for these characteristics. All indicators are calculated as a percentage, their optimal value is 100%, thus, the better the state of the enterprise in terms of organizational development, the higher the values of the developed indicators.
