Authors: Kuftyak E. V. , Magdenko O. V. , Zadorova Ju. A. 
Published: September 2021

Introduction. The attachment is viewed as the base for assessment of individual adaptation variation throughout life. In the capacity of the core indicator of the person’s unison with external environment, the psychological well-being combines the different aspects of child life. The assessment of the psychological well-being is based on three indicators: evidence of life satisfaction; life quality assessment; difficulty levels of external and internal spectrum.The aim of the current publication is to investigate the influence of features of attachment to mother on psychological well-being of primary school-age children.Methodology and research methods. The methodological research framework was based on the main provisions of the attachment theory (J. Bowlby, M. Ainsworth). “Mother-Child Attachment Style Measure Questionnaire” method (Pupyreva, 2007) was employed to identify attachment features. The measure of psychological well-being was carried out by means of “Student’s Life Satisfaction Scale” (Toporkova, Slobodskaya et al., 2015), “Pediatric Quality of Life Inventory” and “Strength and Difficulties Questionnaire” (Goodman, Slobodskaya, Knyazev, 2005) methods. 178 primary school-age children (85 boys and 93 girls) aged 10 to 11 (mean age = 10.2) participated in the research.Results. The analysis of the results showed that secure attachment among children reduces life satisfaction, facilitates the behavioural disorders and psycho-emotional reactions, impacts on limitation of social contacts and life quality. Using the regression analysis, it was revealed that the quality of the correlation between attachment indicators and psychological well-being vary depending on degree of attachment security. It is demonstrated that maternal responsiveness and attentiveness is an absolute predictor of life satisfaction, physical and social well-being and life quality in the primary school-age period, irrespective of the child’s attachment types. The absence of mother-child closeness is the predictor for disruption of physical, emotional and social functioning, low level of life quality in insecure attachment in primary school-aged children.Scientific novelty. The specificity of psychological well-being of primary school-aged children with different types of attachment to their mother is determined. It is shown for the first time that characteristics of attachment are the predictors of life satisfaction, quality of life, and mental health of primary school-aged children.Practical significance. By identifying different regression models for the description of psychological well-being on the basis of child-mother attachment indicators, it may be possible to provide interventions to improve psychological well-being based on the characteristics of attachment.

Introduction. New digital technology in education and its constantly evolving paradigm have completely transformed the model of learning and the learning methods. E-learning has become an important tool for teaching and learning environments. Moreover, virtual learning has become a required alternative teaching method in educational system change during the COVID-19 pandemic, especially for learners in elementary schools.Aim. This research aimed to explore the necessities, lack, and want of learning English, which is done virtually at home.Methodology and research methods. This research employs descriptive methods using questionnaires and interviews as instruments to get responses from teachers and students about their learning needs. In the course of the needs analysis process, the importance and priority of teachers’ and students’ needs are discussed. The participants of this study were second-grade elementary school students, and the sample was 40 students and 2 English teachers for 10 months.Results. The research results demonstrate a gap between the needs of learners and current conditions; therefore, the whole language approach, the multimedia, and technology-based English teaching materials will become an inevitable need and even become a solution in the world of education.Scientific novelty. Further research is needed to study educational system change during the COVID-19 pandemic or after, especially in designing teaching materials in various disciplines and at different educational stages. Future studies could be generalised by these research findings to other populations in different learning contexts, and the findings presented in thisarticle should be further explored. In particular, technology-based and multimedia-based teaching materials must be explored more deeply. Furthermore, further research should focus on utilising a different model for needs analysis in language education to verify the need for effective English learning in changing the education system during the pandemic and after.Practical significance. It is thought that this study will contribute to the stakeholders in terms to provide empirical evidence of what necessities, lack, and want should be considered when a teacher will design and develop teaching materials during the COVID-19 period or afte.

Introduction. This article examines the modern educational approach in the field of liberal arts and practical finance, democratisation of the decision-making system in educational institutions through the active engagement of students on the example of US schools and universities. This approach is based on initiative, or participatory budgeting, i.e. students are involved in the process of allocation of budgetary funds of schools and universities. Such participatory practice has educational and administrative objectives, as it serves to improve the quality management in educational institutions through the involvement of students in major decisions. Taking into account the fact that students are the key beneficiaries of the education system, their opinions lead to increased efficiency in educational institutions.Aim. On the basis of real cases, the current research is aimed to identify and describe participatory techniques that can integrate the teaching of theoretical knowledge in the field of civil society with the formation of practical skills in this area.Methodology and research methods. Desk research method of analysing primary and secondary sources (websites of educational institutions, academic publications, and articles in the media) and the field sociological method of expert interviews were used. Expert interviews with representatives of schools and universities, teachers, officers from educational institutions, consultants from the Participatory Budgeting Project, the leading consulting organisation in North America were conducted.Results. The results of the study reveal several participatory techniques for students’ engagement in the allocation of budgetary funds of schools and universities that are applied in New York and Arizona. The identified and described technologies of participation contribute to the formation of students’ knowledge of socio-economic disciplines, practical finance and civics, project management skills, as well as an increase in civic engagement.Scientific novelty.The present study expands the ideas about how to improve the process of teaching social and economic disciplines at schools and universities, practical finance and project management. The method of improving the efficiency of educational institutions through democratic practices is identified.Practical significance. In the future, the proposed approach can be applied in Russian educational institutions.

Abstract
Background: Medical wastewater from hospitals specializing in infectious diseases is a major health and environmental risk during pandemics. However, few systematic studies on medical wastewater management in hospitals of infectious diseases have been reported. As designated emergency field hospital for the treatment of COVID-19, the Huoshenshan Hospital achieved successful outcomes on emergency management measures of medical wastewater.Results: The lessons of medical wastwater based on Huoshenshan Hospital can be concluded following four aspects: (1) Emergency management system of medical wastewater based on the “Internet Plus” technology, and other related management schemes and standard systems provided legislative foundation for emergency management of medical wastewater. (2) The three-tier prevention and control system of medical wastewater ensured the discharged wastewater meets water quality standards. The system specifically included the individual seep and leak-proof sealed collection system at the first tier, as well as the enhanced disinfection and moving bed bioﬁlm reactor wastewater biological and chemical treatment technology at the second tier. (3) The study established an effective three-tier accountability system in medical wastewater quality monitoring, data recording, storage, and reporting, as well as data review and filing, especially in continuous data monitoring and dynamic analysis of characteristic indicators. (4) Information disclosure by government and public supervision promoted successful implementation of medical wastewater management and control measures. Based on the results of 212 public questionnaires, we also confirmed that information of the case was open to public and internet users who actively participated. Conclusion: Our study will provide methodological reference for the emergency management of wastewater in designated infectious disease hospitals in similar situations.
Generalized Relational Tensors For Irregularly Sampled Time Series: Methods To Store, Re-generate, And Predict
Authors: Gromov Vasilii , Necheporenko Anastasia , Gaisin Andrei , Volkov Ilya , Diner Stanislav 
Published: September 2021

Abstract
The paper deals with a generalized relational tensor, a novel discrete structure to store information about a time series, and algorithms (1) to fill the structure, (2) to generate a time series from the structure, and (3) to predict a time series, for both regularly and irregularly sampled time series. The algorithms combine the concept of generalized z-vectors with ant colony optimization techniques. In order to estimate quality of the storing/re-generating procedure, a difference between characteristics of the initial and regenerated time series is used. The structure allows working with a multivariate time series, with an irregularly sampled time series, and with a number of series as well. For chaotic time series, a difference between characteristics of the initial time series (the highest Lyapunov exponent, the auto-correlation function) and those of the time series re-generated from a structure is used to assess the effectiveness of the algorithms in question. The approach has shown fairly good results for periodic and benchmark chaotic time series and satisfactory results for real-world chaotic data.
WITHDRAWN: Efficient Facial Emotion Recognition Model using Deep Convolutional Neural Network and Modified Joint Trilateral Filter
Authors: Kumari Naveen , Bhatia Rekha 
Published: September 2021

Abstract
Facial emotion recognition extracts the human emotions from the images and videos. As such, it requires an algorithm to understand and model the relationships between faces and facial expressions, and to recognize human emotions. Recently, deep learning models are extensively utilized enhance the facial emotion recognition rate. However, the deep learning models suffer from the overfitting issue. Moreover, deep learning models perform poorly for images which have poor visibility and noise. Therefore, in this paper, a novel deep learning based facial emotion recognition tool is proposed. Initially, a joint trilateral filter is applied to the obtained dataset to remove the noise. Thereafter, contrast-limited adaptive histogram equalization (CLAHE) is applied to the filtered images to improve the visibility of images. Finally, a deep convolutional neural network is trained. Nadam optimizer is also utilized to optimize the cost function of deep convolutional neural networks. Experiments are achieved by using the benchmark dataset and competitive human emotion recognition models. Comparative analysis demonstrates that the proposed facial emotion recognition model performs considerably better compared to the competitive models.

Published: September 2021

Abstract
In this work we dissect the osteoinductive properties of selected bioactive materials obtained in a 3D form, and based on PLGA matrix and 2 types of gel-derived bioactive glasses (SBGs) of SiO2-CaO system, each with and without P2O5. The study is designed to avoid any osteogenic stimuli beyond the putative osteogenic bioactive glass compound of the studied materials. Previously we found that, when used as growth surfaces (i.e. material sheets), some of these materials were capable to support osteogenesis of bone marrow stromal cells (BMSC) without the need for any additional osteogenic cell treatment. In this work we explore further the role of BMP production and signaling upon BMSC culture on selected, SBG/PLGA 3D scaffolds as well as BMSC migration toward the condition media obtained from such cell-loaded materials. Our results show that BMP signaling of osteoprogenitor cells as well as their migration rate may present important indicators of materials osteoinductivity.

Published: September 2021

Abstract
Sex is a key biological variable in traumatic brain injury (TBI) and plays a significant role in neuroinflammatory responses. However, the molecular mechanisms contributing to this sexually dimorphic neuroinflammatory response remain elusive. Here we describe a significant and previously unreported tissue enrichment and sex specific alteration of a set of inflammatory microRNAs (miRNAs) in CD11b + cells of brain and bone marrow isolated from naïve mice as well as mice subjected to TBI. Our data from naïve mice demonstrated that expression levels of miR-146a-5p and miR-150-5p were relatively higher in brain CD11b + cells, and that miR-155-5p and miR-223-3p were highly enriched in bone marrow CD11b + cells. Furthermore, while miR-150-5p and miR-155-5p levels were higher in male brain CD11b + cells, no significant sexual difference was observed for miR-146a-5p and miR-223-3p. However, TBI resulted in sex specific differential responses of these miRNAs in brain CD11b + cells. Specifically, miR-223 levels in brain CD11b + cells were markedly elevated in both sexes in response to TBI at 3 and 24 hr, with levels in females being significantly higher than males at 24 hr. We then focused on analyzing several miR-223-3p targets and inflammation-related marker genes following injury. Corresponding to the greater elevation of miR-223-3p in females, the miR-223-3p targets, TRAF6 and FBXW7 were significantly reduced in females compared to males. Interestingly, anti-inflammatory genes ARG1 and IL4 were higher in females after TBI than in males. These observations suggest miR-223-3p and other inflammatory responsive miRNAs may play a key role in sex-specific neuroinflammatory response following TBI.
Alexander invariants and cohomology jump loci in group extensions
Authors: Suciu Alexander I. 
Published: September 2021

Abstract

We study the integral, rational, and modular Alexander invariants, as well as the cohomology jump loci of groups arising as extensions with trivial algebraic monodromy. Our focus is on extensions of the form 1→K→G→Q→1, where Q is an abelian group acting trivially on H1(K;ℤ), with suitable modifications in the rational and mod-p settings. We find a tight relationship between the Alexander invariants, the characteristic varieties, and the resonance varieties of the groups K and G. This leads to an inequality between the respective Chen ranks, which becomes an equality in degrees greater than 1 for split extensions.
Kilka uwag o medalach portretowych Zygmunta I Starego
Authors: Grzęda Mateusz 
Published: September 2021

Na początku XVI w. medal portretowy był jedną z najoryginalniejszych form reprezentacji, która dzięki dużej ilości informacji na temat przedstawionej osoby, skumulowanej w niewielkim, trwałym, mobilnym i łatwym do powielenia przedmiocie, doskonale odpowiadała renesansowemu postulatowi sławy i nieśmiertelności. Możliwości, jakie oferował ten gatunek artystyczny, zostały zauważone w dworskim kręgu Zygmunta I Starego (1507–1548), co zaowocowało kilkoma seriami lanych i bitych w różnych metalach medali przedstawiających polskiego króla, powstałych na przestrzeni drugiego i trzeciego dziesięciolecia XVI w. W artykule rozwadze poddano proweniencję artystyczną tych medali, okoliczności ich powstania oraz rolę, jaką mogły one pełnić w praktyce władzy Zygmunta I.
Summary:
At the dawn of the sixteenth century portrait medals counted among the most orginal forms of representation which providing plenty of information on represented individual and accumulating it in a small, durable, mobile and easily reproducible object, met the Renaissance demand of fame and immortality. Advantages of this medium have been noticed in the courtly circle of king of Poland Sigismund I the Old (r. 1507–1548) thus leading to creation of several series of medals cast and strack in various metals in the second and third decade of the sixteenth century. The paper discusses authorship of these medals, as well as circumstances of their production and the role they could have played in the propaganda of Sigismund I’s power.
Polonorum Icones – zbiór „wyobrażeń ludzi w ojczyźnie znakomitych, na hołd potomności zasługujących”. Przyczynek do kształtowania kolekcji Gabinetu Rycin króla Stanisława Augusta
Authors: Przepałkowska Izabela 
Published: September 2021

Zespół portretów sławnych Polaków Polonorum Icones powstał jako część kolekcji Gabinetu Rycin króla Stanisława Augusta. Wbrew dotychczasowym ustaleniom jego kształtowanie przypada na wcześniejsze lata niż rok 1778. W artykule podjęto próbę ukazania wpływu relacji między Poniatowskim a Michałem Mniszchem na formowanie się omawianego zespołu portretów oraz jego zależności od idei utworzenia Museaum Polonicum.
Summary:
The set of portraits of famous Poles, called Polonorum Icones, was a part of the Print Room of Stanisław August Poniatowski, the king of Poland. In spite of the opinion of previous researchers, this set of portraits was shaped earlier than 1778.
This article attempts to reveal the influence of the relation between King Poniatowski and Michał Mniszech on the formation of the discussed set of portraits. The author also raises the issue of the dependence of Polonorum Icones on the idea of creating Museaum Polonicum.
