Authors: DANYSKO O. , SEMENOVSKA L.
Published: December 2021

The development of information and communication technologies and their integration into the educational space of higher education institutions has led to the emergence of new models of professional training. One of the innovative strategies that combine the best practices of traditional (face-to-face) and electronic (synchronous / asynchronous) learning interaction is blended learning. The perception of teachers who provide the educational process is a major predictor of the implementation of such strategies and models. The purpose of the study is to summarize and interpret the experience of teachers in blended learning and analyze their perception of the possibilities of its use in the training of future teachers of physical education. The research was conducted by anonymous and voluntary questionnaires using an open electronic questionnaire. The sample consisted of 28 teachers who provide training for future teachers of the subject specialty 014.11 Secondary education (Physical Culture) in various domestic institutions of higher education in Ukraine. The analysis contains a description of the quantitative and semantic interpretation of the obtained data. The generalization of the obtained data and their analysis showed that blended learning is generally positively perceived by teachers as a technology that contributes to the flexibility of the educational process, accessibility of educational content, improving student attendance, enriching teaching aids, their interactivity, and thus improving the training of future physical culture teachers. Despite the challenges and difficulties of organizing the educational process in a blended learning environment, it is established that the organization of such training also helps to improve the professional skills of teachers, improve academic courses, creative search for effective pedagogical and technological solutions to ensure quality education.
THE ROLE OF ZEMSTVOS IN THE FORMATION OF TEACHER TRAINING
Authors: SAVCHENKO S. , FAZAN V.
Published: December 2021

Zemstvos have become one of the most important sources of education for the Ukrainian people. They began to appear in Ukraine in 1865-1866. These were elected bodies, but their activities were controlled by the governor and the interior minister. It should be noted that the main composition of the zemstvos were intellectuals and public figures. One of the responsibilities of zemstvos was to support and control public education. It was in this area that the zemstvo activity proved to be the most successful. Zemstvos had to start school in very difficult conditions not only because funds for public education became “optional” (according to the “Regulations on Zemstvo Institutions”, approved in 1864, where the cost of public education was included in the number of optional and zemstvos had no right to interfere in the educational process of the school), but also because public schools were in great decline - there was a lack of premises, teachers, textbooks. In addition, it should be noted that all zemstvos were willing to undertake the establishment of primary schools, but not all could implement their plans. And during the first decade of the zemstvos the number of zemstvo primary schools increased significantly.An important issue was the preparation of teachers for professional activities in zemstvo schools, a significant place wasgiven to the problems of educational work with adults - the organization of Sunday schools, public readings, popular science lectures, libraries, cultural and educational events. For example, such issues were included in the program of pedagogical courses organized in 1894 in Chernihiv under the guidance of the famous teacher D. Tikhomirov .The zemstvo played an extremely important role not only in the organization of the educational process among children and adults, but also in the training of professional staff. All possible resources were used to make the teacher an experienced and versatile person. A separate socio-professional group was formed - the zemstvo teachers, which was distinguished by the presence of an organizationally designed coordinating basis for being within a single socio-professional group - zemstvo institutions that provided professional training.

Published: December 2021

The article for the first time in domestic science systematizes the history of formation and development of Ukrainian centers for the study of the creativity heritage of the outstanding teacher and writer A. Makarenko. It is emphasized that Ukraine is an integral and important part of the world Makarenko studies process, it has been at the origins of this area of research and has remained one of its driving forces for many years.The first independent Makarenko center of Ukraine was a research center formed at the Ivan Franko Lviv State University. Its initiator and long-term leader was F. Naumenko, who in the difficult socio-political conditions of the Western Ukrainian community managed to actualize in the first postwar years this promising scientific direction, unite around him young scientists and create a powerful Makarenko school. Authoritative and one of the oldest Ukrainian centers for the study of the heritage of A. Makarenko is the Kharkiv Makarenko School, personified by scientists of the Kharkiv National Hryhoriy Skovoroda Pedagogical University. A characteristic feature of this scientific center is the almost equivalent representation in it of both pedagogical and literary directions of A. Makarenko’s heritage development. The proximity of Poltava V. Korolenko Pedagogical University with the name of an outstanding teacher-reformer inspires bright traditions of research activity of student and teaching staff, including the activities of Makarenko’s student group, Research Laboratory of A. Makarenko and International and All-Ukrainian Makarenko Center, the creation of the State Museum-Reserve A. Makarenko in the village of Kovalivka near Poltava and the Internet resource “Makarenkiana”, holding annual international scientific conferences, unique editions of archival documents and more. Sumy State A. Makarenko Pedagogical University is also a powerful Makarenko center, which has a deep tradition of development of this area of historical and pedagogical science.

Authors: Serra de Arruda Fabiana , Perira Almeida Marcelo , Pires Vieira Daniel
Published: December 2021

Este trabalho objetiva analisar a relação entre o nascimento do primeiro filho e a atitude dos pais quanto à escolha do modo de transporte utilizado. O nascimento do primeiro filho é apontado na literatura como evento de importância na decisão dos pais sobre qual modo de transporte utilizar. A pesquisa analisou a atitude dos pais em relação a cinco variáveis relativas aos deslocamentos, antes e após o nascimento do primeiro filho. Os dados usados foram coletados em domicílios com crianças até seis anos de idade. Os resultados mostram que quando não houve a mudança de modo de transporte após o nascimento da criança, não houve mudança de atitude dos pais. Esse resultado permite concluir que o nascimento da criança por si só não é condição suficiente para a mudança de atitude dos pais quanto ao modo de transporte usado.

Partindo dessas premissas, esse texto objetiva analisar as nuances decorrentes de tais interações entre Brasil e Argentina, a partir da rede de transporte aéreo de passageiros, sua evolução, organização e diferentes formas de estratégias logísticas sob a perspectiva da Geografia dos Transportes.
Political Communication on Facebook
Authors: Minussi Priscila
Published: December 2021

The citizens' weakened confidence in politics has encouraged political actors to establish direct communication with them. As social media platforms grow in popularity, political institutions have been using them for more autonomy in public communication. This study analyses the use of Facebook, the most popular social media worldwide, by República Portuguesa, the government of Portugal, and La Moncloa, the government of Spain. First, a literature review on social media use by governments is presented. Then, the results of a manual categorization of a sample of posts published throughout January 2021 are presented. The posts were categorized according to DePaula, Dincelli and Harrison’s (2018) typology of government social media communication, which consists of information provision, input seeking, online dialogue/offline interaction, and symbolic presentation. The article provides an understanding of the use of each governmental party’s Facebook posts as a communication tool.

Authors: Chan KC , Rudolph J , Tan S
Published: December 2021

This paper expounds on applied learning and teaching transformations through project-based action learning for students’ self-awareness and effective competence development. After providing some background to the Indonesian university where the research took place and a brief review of the literature, we describe the methodology. The article is based on longitudinal action research over 13 years that used a mixed-methods survey that generated multiple testimonials that were assessed via thematic content analysis. Six phases of learning innovations are discerned: Awareness, alignment, action, adoption, assurance and anticipation. These phases of the transformational process also provide the structure for the findings and discussion section. To succeed, international business management graduates have to continuously strategise, implement, and incorporate a closed-loop feedback system to track and manage individual progress with an action learning balanced scorecard. As whole-brain learners, the pursuit of knowledge must be transformed into a value-added advantage in four types of interconnected and interdependent power.

Strengthening the COVID-19 pandemic response, global leadership, and international cooperation through global health diplomacy
Authors: Javed Sumbal , Chattu Vijay Kumar
Published: December 2021

The coronavirus disease 2019 (COVID-19) pandemic continues to claim lives around the world and, to some extent, reflects the failure of international cooperation. Global health diplomacy (GHD)can be a bridge for international cooperation for tackling public health crises, strengthening health systems through emphasizing universal health coverage for sustainable and equitable development, and rebuilding multilateral organizations. It can be a catalyst for future global health initiatives. Health should not be used as a political tool at the cost of people’s lives, nor should it become a proxy for geopolitics but can be used to diffuse tensions and create a positive environment for political dialogue. Health diplomacy’s focus should be to mitigate inequality by making available diagnostics, therapeutics, and vaccines as a global public good. The implications for the lack of international cooperation will lead to increased global disparities and inequities as the countries that cannot procure vaccines will find their population more vulnerable to the pandemic’s repercussion. Though the international cooperation on trade has suffered the impact of geopolitical shifts and competition, through engaging in GHD, the governments can align the trade and health policies. Amid this global health crisis, the World Health Organization (WHO) has faced an increase in International Health Regulations violations, limiting its influence and response during this COVID-19 pandemic. Nations need to develop a sense of cooperation that serves as the basis for a mutual strategic trust for international development. The priorities of all the countries should be to find the areas of common interest, common operational overlap on development issues, and resource allocation for this global fight against COVID-19.

Published: December 2021

У статті окреслено освітні можливості соціальних мереж у професійній підгото-вці майбутніх педагогів. Авторка зазначає, що в умовах швидкого розвитку цифрових технологій змінюються й освітні тренди, врахування яких дозволяє закладам вищої освіти вносити корективи у процес професійної підготовки майбутніх фахівців відповідно до потреб сучасного цифрового суспільства.У процесі дослідження означеної проблеми нами використано методи аналізу і синтезу; порі-вняння та узагальнення; теоретичні методи, пов’язані з вивченням наукової літератури, періодич-них видань. Пошук інформації здійснювався в електронній базі Google Scholar, українських і зарубіжних веб-сайтах.Розкрито сутність поняття «соціальні мережі». Проаналізовано реальний стан реєстрації здобувачів вищої освіти у різних соціальних мережах. Визначено популярність соціальних мереж серед студентів педагогічного факультету Прикарпатського національного університету імені Василя Стефаника. Детально охарактеризовано особливості соціальних мереж, зокрема таких, як Facebook, Instagram та визначено переваги їх використання у професійній підготовці майбутніх пе-дагогів.Результати проведеного дослідження дають підстави стверджувати, що соціальні мережі доцільно використовувати для організації колективної роботи, проєктної діяльності; мобільного неперервного навчання в умовах карантину, спілкування між учасниками освітнього процесу під час проведення різних виховних заходів, конференцій, семінарів, вебінарів, майстер-класів; для пошуку необхідної навчальної інформації, статей, монографій, підручників, перегляду навчальних відео та новин; для вивчення іноземних мов; самоосвіти тощо.Зроблено висновки, що сучасна молодь більшу частину свого часу проводить у соціальних ме-режах, тому вони мають стати не лише простором для спілкування і розваг, а й місцем навчання, інноваційним інструментом для цілеспрямованого використання в освітньому просторі закладів вищої освіти.Перспективами подальших наукових пошуків є визначення готовності викладачів закладів вищої освіти до використання соціальних мереж у власній професійній діяльності

Authors: Rodríguez-Montoya Ronald Milton , Hilario-Vargas Julio Santos , Alcántara-Gutti Manuel Enrique
Published: December 2021

Background: Patients with severe COVID-19 evolve to acute respiratory distress syndrome (ARDS) and require management in Intensive Care Units (ICU) where they are exposed to immobilization, immunosuppression, malnutrition, nosocomial infections; may develop ICU Acquired Weakness (ICUAW), which increases with the stay and use of mechanical ventilation (MV).There is evidence of the use of different modalities in rehabilitation to mitigate these effects. Goal: To determine the efficacy of a Multimodal Rehabilitation Program (MRP) in reducing the number of days of mechanical ventilation and stay in patients hospitalized for COVID-19 in ICU, as well as to describe its clinical and hospital characteristics. Material and Methods: An quasi-experimental study was designed, with sequential sampling and without blinding. A control and intervention group was formed, with 32 participants each. A Multimodal Rehabilitation Program (MRP) based on four therapeutic modalities was applied and the intervention was quantified through the use of proposed indicators. Results: The variation in days of ICU stay and days of MV were similar in both groups. The Multimodal Rehabilitation Index (iMR) ranged from 0.1 to 2.7 (mean = 1.2, SD = 0.7) and had significance for cut-off points ≤ 0.81 and ≤ 0.94 in mortality (p = 0.02) and Ventilator-free days at 28 days (VFDs-28) (p = 0.01). Conclusions: No statistically significant difference was found in favor of the intervention in terms of days of stay in the ICU and days of MV. Explanatorily, it was reported that iMR was related to (VFDs-28) and mortality in patients with severe COVID-19.

Authors: Meregildo-Rodriguez Edinson Dante , Asmat-Rubio Martha Genera , Sánchez-Carrillo Halbert Christian , Chavarri-Troncoso Frank Poul
Published: December 2021

Background and Objetives: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are considered as a continuum of the same process. TEN or Lyell Syndrome is the most severe form. Both entities involve an acute mucocutaneous blistering reaction associated with systemic inflammation. Materials and Methods: We present a case of a young woman who developed TEN following concomitant treatment with valproate, lamotrigine, and phenobarbital. Despite the extensive mucocutaneous detachment (over 90%), prognostic evaluation was favorable (SCORTEN score 2; probability of survival 88%), and this patient evolved satisfactorily. Five days after admission, valproate was reinitiated without any subsequent adverse reaction. Results: Causality evaluation identified both lamotrigine and phenobarbital as “very probable” (ALDEN score = 6) causes and valproate as “very unlikely” (ALDEN score = 0) cause of TEN. Conclusions: SJS and TEN are true life-threatening medical emergencies. This case emphasizes the importance of early diagnosis and treatment, including the discontinuation of the causative agent, which can be lifesaving.

Authors: Zarate Vanessa , Cahuata Alejandra , Díaz Roxana , Alvarado-Gamarra Giancarlo , Chonlon Kenny , Domínguez-Rojas Jesús Angel
Published: December 2021

Background: We describe an 8-month-old boy with leukemia and SARS-CoV-2 infection who developed Kasabach-Merritt phenomenon. He had a positive SARS-COV-2 RT-PCR sample. Hematologic tests showed coagulopathy and intestinal involvement. She was managed in emergency receiving transfusion support and in hospitalization with social isolation measures, she started propanolol and corticotherapy as initial treatment of infantile angiomas. She presented with symptoms of intestinal obstruction and underwent surgery and evidence of hemorrhagic infarction with foci of intestinal ischemic necrosis, ending in ileostomy. We tried to understand a pathophysiological explanation of the dermatologic and gastrointestinal tract involvement by the virus and the atypical form of COVID-19. Given the emerging evidence of endothelial and vascular involvement in COVID-19, the development of tests to detect vascular lesions may be critical to guide the use of new therapeutic strategies.

Çalışmanın bulguları arasında, çalışmaya atfedilen anlamın tarihsel süreçte değişime uğradığı, günümüz modern toplumlarında insan onuruna uygun iş kapsamında çalışma ortamlarının düzenlenmesi gerektiği, aynı zamanda çalışmaya ait bireysel yönelimlerin sağlanmasında bireysel sorumluluğun olduğu, bunun sağlanamaması durumunda sosyal çalışma uygulamaları kapsamında psiko-sosyal çalışmaların yapılması gerektiği yer almaktadır. Çalışmanın sonucu, merkezi iradelerin sosyal diyalog kapsamında insan onuruna uygun, çalışma barışını önceleyen istihdam alanlarının yaygınlaştırılmasıyla ilgili görevlerinin olduğudur. Bu görev aynı zamanda davranışın temelinde yer alan sorumluluk bilinci kapsamında bireysel görevdir. Her iki durumda da insan onurunun korunması için yapısal ve davranışsal temelde düzenlemeleri destekleyecek uygulamalara gereksinim vardır.

Rice straw, an abundant agricultural waste, possesses immense potential to serve as renewable, eco-friendly and non-edible feedstock to generate value-added products. Therefore, the present study aimed to obtain prebiotic neutral xylooligosaccharides (XOS)-rich autohydrolysate from rice straw xylan. The central composite design of response surface methodology was employed to optimize the conditions for the alkaline extraction of xylan, i.e. NaOH concentration (6-14%, w/v), reaction time (1-3.5 h) and temperature (50-100 °C). Autohydrolysis of xylan was carried out at 121 °C and 15 psi for varied hydrolysis times (10, 25 and 40 min) and sulphuric acid concentrations (0.1, 0.5 and 1.0M) to obtain XOS-rich autohydrolysate. The optimum conditions were found to be as follows: 11.04% (w/v) NaOH, 3.126 h and 80.146 °C, so that the maximum xylan yield of 19.97% was predicted by the software. This value was quite close to the experimental yield of 19.4%, with 80.83% xylan being recovered per gram of rice straw. The best autohydrolysis treatment for xylan was found to be using 0.1M sulphuric acid for 10 min, which allowed 34.5% of 100 mg xylan to be depolymerized to produce neutral XOS (degree of polymerization up to 7), with xylose, xylobiose and xylotriose constituting 4.45, 10.14 and 7.83 mg, respectively. These autohydrolysates promoted higher growth of Lactobacillus rhamnosus and Lactobacillus casei than established prebiotic fructooligosaccharides. The study attempts to solve disposal issues of rice straw through production of XOS-rich autohydrolysates in demand on the global nutraceuticals market.

In this study, the effects of Lavandula angustifolia, Tilia cordata and Rosa canina on cellulose production by Komagataeibacter intermedius strain were investigated. T. cordata was found as the most effective plant (10.64 g/L BC), under the following optimized conditions: 50 g/L plant amount, 8% lactose, 15% inoculum amount at pH=6.0. Total phenolic contents of L. angustifolia (55.42 mg/g), R. canina (16.54 mg/g) and T. cordata (60.03 mg/g), and total protein amounts of L. angustifolia (7.89 g/L), R. canina (3.54 g/L) and T. cordata (5.13 g/L) were analyzed. It has been established that phenolic and protein substances contribute significantly to cellulose formation. Physicochemical analysis showed that all the peaks obtained from FTIR analysis are distinguishable for BC and pellicles show high thermal stability. This research work is the first report on the usage of L. angustifolia, R. canina and T. cordata plants as low-cost substrates in BC production with high yields.

The present study aimed to characterize Pleurotus eryngii and P. pulmonarius ligninolytic enzymes and to determine their potential for polymer degradation in common agroforestry residues. The peak of laccase activity (36052.33 U L-1) was observed after P. pulmonarius cultivation on oak sawdust. The maximal Mn-dependent peroxidase activity was reached by P. eryngii (2511.36 U L-1), while the highest level of versatile peroxidase activity was noted in P. pulmonarius (3053.03 U L-1), after fermentation of corn stalks. The highest level of lignin loss (46.28%) was achieved after cultivation of P. pulmonarius on corn stalks, but the most selective degradation of lignocellulose polymers was observed after P. eryngii cultivation on wheat straw. The obtained results lead to the conclusion that the studied P. eryngii and P. pulmonarius strains are good producers of ligninolytic enzymes and effective and selective depolymerizers of agroforestry residues, and therefore their use would be beneficial in numerous environmentally friendly technologies.

We investigated the optimization of bacterial cellulose (BC) production from sugar beet molasses by Gluconacetobacter xylinus NRRL B-759 in static culture. The optimization studies were performed using the central composite design (CCD) of response surface methodology (RSM). The independent variables were the molasses concentration, inoculation ratio and culture volume. The dependent variable was BC production yield. From the optimization tests, based on the model developed by RSM-ANOVA, it was found that binary interactions between molasses concentration–culture volume and inoculation ratio–culture volume had the most significant influence on the responses. The optimum conditions were as follows: 78.932 g/L molasses concentration, 12.973% inoculation ratio, and 130.405 mL of culture volume. The obtained BC was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and elemental analysis. The characterization results obtained in the study revealed that the produced BC exhibited typical FTIR spectrum, elemental composition, and nanofiber structure.

Starch–carboxymethyl cellulose (CMC) bioplastics have limited mechanical properties. Carrageenan from seaweed is a potential reinforcement material for improving the mechanical properties of bioplastics. This study aimed to determine the effect of Kappa (κ)-carrageenan on the mechanical and thermal properties and biodegradability of starch–CMC bioplastics. In this study, carrageenan at concentrations of 0%, 10%, 15%, 20%, 25% and 30% was used. The melt-mixing process was conducted at 130 °C for 4 min, using a mixer and then hot-pressing (30 kgf/cm2) at 150 °C for 5 min. The results indicated that the higher κ-carrageenan concentration increased the strength of bioplastics up to 15.7 MPa. The fracture analysis via scanning electron microscopy–energy-dispersive X-ray spectroscopy indicated the distribution of sulfur (S) elements that described the dispersion of κ-carrageenan. The Fourier transform infrared spectroscopy spectra revealed that the interaction between the starch–CMC matrix and κ-carrageenan formed a tight hydrogen bond network. The lowest mass reduction observed by thermogravimetric analysis occurred in bioplastics with 25% carrageenan, decreasing by 48% compared with bioplastics without κ-carrageenan. The addition of κ-carrageenan was identified as not affecting the biodegradability of the bioplastics.

Stinging nettle was used as lignocellulosic adsorbent for the removal of cationic dye – malachite green (MG), and anionic dye – Congo red (CR), from aqueous solution, without any chemical pretreatment. The adsorption equilibrium data fitted well with the Langmuir model for the adsorption of both dyes, with the calculated maximum adsorption capacity of 270.27 mgg-1 and 172.14 mgg-1 for MG and CR, respectively. The adsorption process was controlled by the pseudo-second-order model in the adsorption of MG and by the pseudo-first-order model in the adsorption of CR. The thermodynamics modelling displayed that the process was spontaneous and endothermic. The π–π electron–donor interaction, hydrogen bonds and pore diffusion may also be effective, besides electrostatic interaction between the adsorbate and the adsorbent in the mechanism of MG and CR uptake.
Effect of an external sound superimposed on the self-excited oscillation in a loop-tube thermoacoustic system

Published: December 2021

The influence of an external sound applied to a loop-tube type thermoacoustic system on the energy conversion efficiency is experimentally examined. The investigation is carried out by studying the effect of a loudspeaker (SP) set as an external sound source. As a result, it is found that the location of the SP affects the sound field in the system and that the amount of energy generated increases or decreases. The increasing or decreasing effect differs depending on the location of the SP. Furthermore, it is confirmed that, provided the SP is located near the particle velocity node, the sound energy can be increased by more than the input power to the SP without changing the sound field in the tube. From these results it can be confirmed that, similar to a straight-tube type thermoacoustic system, the energy conversion efficiency can be enhanced by locating the SP at a suitable position even in a loop-tube type system without end surfaces.
