This study aimed to examine the pregnancy outcomes in women infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with and without underlying diseases in western Iran. This case-control study compared 49 pregnant women with Coronavirus disease (COVID-19) with underlying diseases (the case group) and 49 women with COVID-19 without underlying diseases (the control group). The groups were pregnant women with COVID-19 admitted to Hamadan hospitals for delivery. COVID-19 was diagnosed by using the reverse transcriptase-polymerase chain reaction (real-time RT-PCR). Data were evaluated using a checklist. Further, the Statistical Package for the Social Sciences (SPSS) version 16 was used for data analysis. A value of p<0.05 was considered statistically significant. The odds of preterm labor were five times higher in women with underlying diseases (OR=5.95, 95% CI (3.01, 7.15), p=0.034). Moreover, the odds of preeclampsia and eclampsia in women with underlying diseases was (OR=3.35, 95% CI (1.18, 4.93), p=0.048) and (OR=2.65, 95% CI (1.43, 3.54), p=0.035), respectively. The results revealed that preterm labor, preeclampsia, and eclampsia were significantly higher in women with COVID-19 and underlying diseases compared to those without underlying diseases. Thus, the need to identify and educate pregnant mothers on underlying diseases and attention to prenatal care, particularly in high-risk groups, is necessary for the COVID-19 pandemic.

Recent data suggest that the prevalence of Helicobacter pylori (HP) infection in Romania has been declining in the last 30 years. However, there are no studies regarding HP prevalence among medical students. The objectives of this study were to estimate the prevalence of HP infection and assess the prevalence of dyspepsia in medical students and the relationship between dyspepsia and infection. We included 150 students from the Iuliu Hatieganu University of Medicine and Pharmacy of Cluj-Napoca, Romania (102 females and 48 males, mean age 21 years). Each student completed a lifestyle questionnaire, personal history, family history as well as the Rome IV questionnaire for functional dyspepsia. The status of HP infection was determined using the C13-urea respiratory test. The prevalence of HP infection was 25.33%, and 18% met the Rome IV criteria for functional dyspepsia. 37% of students with functional dyspepsia had a positive HP test. Of all students, 8% had a history of HP infection. Those with a history of HP infection had a 4.45% (95% CI 1.6 – 12.37) higher risk of having positive Rome IV criteria for functional dyspepsia than those with no previous history of infection (p=0.008). Thus, the present study adds to the body of evidence regarding HP prevalence among medical students, 25.33% being positive. We found no statistically significant correlation between HP infection and functional dyspepsia. Those with a history of HP infection had a higher risk of functional dyspepsia.

Introduction. Vitreous opacities are quite common, occurring in 76% of cases and significantly reducing quality of life in 33% of them. YAG-laser vitreolysis is considered as an alternative treatment option for patients with floating vitreous opacities. Purpose. To develop an optimized YAG-laser vitreolysis technology based on the assessment of the acoustic density of the vitreous opacities. Material and methods. The results of YAG-laser vitreolysis of vitreous opacities in 318 patients (318 eyes) were analyzed. A photo-optical method has been developed for visualizing opacities of the vitreous body, registering the area of opacities and the dimming intensity index. A method has been developed for the personalized selection of laser energy taking into account the acoustic density of the vitreous opacities. Results. After performing multi-stage laser treatment, a significant decrease in the area of opacities and the dimming intensity index, an increase in the threshold of retinal photosensitivity according to microperimetry data and a decrease in the acoustic density of opacities were noted. Conclusions. Application of optimized YAG-laser vitreolysis technology for vitreous opacities allows to achieve the best values of clinical and functional parameters (p<0.05). Key words: vitreous body opacities, photo-optical method, efficiency of YAG-laser vitreolysis

Purpose. To describe the clinical cases and surgery results in patients with concomitant of keratoconus and Fuchs' corneal endothelial dystrophy. Material and methods. Retrospective analysis of 3 patients using different surgical techniques. All patients were female, they underwent diagnostic procedures including: keratotopography, optical coherence tomography of the anterior segment of the eye, Scheimpflug keratotomography, endothelial microscopy. First patient underwent penetrating keratoplasty (PKP), the second one – descemet stripping automated endothelial keratoplasty (DSEK), and the third one – descemet membrane endothelial keratoplasty (DMEK). Results. In all cases the combination of keratoconus and fuchs endothelial corneal dystrophy occurred in one eye, while cornea guttata was observed in both eyes. The diagnosis of keratoconus was complicated by the presence of corneal edema due to endothelial dysfunction. As a result, visual rehabilitation was achieved in 2 patients after PKP and DSEK, and in the third case (DMEK), the presence of pronounced opacities of the stroma in the central zone did not result in increase of visual acuity, despite the good function of the graft endothelium, which required the PKP. Conclusion. Surgical tactics should be based primary on the replacement of the pathologically altered endothelial monolayer (DSEK, DMEK). As for the simultaneous replacement of the corneal stroma (PKP), the decision is based on the progression of keratoconus, the degree of corneal thinning, and the presence of its surface irregularity.

Digitisation or Digitalisation: Diverse Practices of the Distance Education Period in Finland
Authors: Korhonen Tiina , Juurola Leenu , Salo Laura , Airaksinen Johanna
Published: October 2021

This case study explores how Finnish primary school teachers orchestrated school days and how teachers and headmasters organised virtual workplace collaboration and collaborated with parents during a period of distance education forced by the Covid-19 crisis in Spring 2020. The data was collected by interviewing primary and secondary school teachers (n = 15) from eight schools in various parts of Finland. Teachers’ experiences were analysed with qualitative content analysis. In this study, the school is seen as a Complex Adaptive System (CAS) and the Covid-19 crisis as a disorder forcing teachers to adapt to a rapidly changing environment. Teachers are viewed here as innovators who address both pedagogical and digital challenges under abnormal circumstances. We identify diverse practices at different stages of digitalisation during the distance education period within four domains: 1) structures of school days, 2) forms of teaching, 3) collaborative activities of teachers and headmaster, and 4) forms of home and school collaboration. We also identify three groups of enablers of distance education practices: 1) the use of digital technology, 2) digipedagogical competence of the teachers, and 3) the ability of teachers to act as adaptive innovators. We find that teachers’ ability to innovate and to adapt pedagogical and digipedagogical expertise become critical success factors when change is forced upon the educational field. We suggest that the results of this study, portrayed as the enablers and domains of distance education, be utilised in planning post-Covid education. All stakeholders influencing schools at different levels should be included in envisioning and implementing future classroom practices of innovative post-Covid schools.
The Effects of Remote Pandemic Education on Crafts Pedagogy: Opportunities, Challenges, and Interaction
Authors: Kouhia Anna , Kangas Kaiju , Kokko Sirpa
Published: October 2021

The Covid-19 pandemic caused many sudden social changes, including a shift to remote education in many countries. In Finland, remote education also concerns crafts as a standard school subject, combining aspects of art, design, textile, and technology in basic education. Accordingly, Finnish craft teachers faced the unprecedented situation of teaching remotely a subject, which often involves hands-on activities with tangible tools and materials. The present study explores how craft pedagogy has been adapted to remote education by looking at the opportunities and challenges it faces and the effects on classroom interaction. The data consist of the output of two webinars (i.e. 27 group assignments from 123 participants) organised in the autumn of 2020 and targeted at craft teachers and student craft teachers at various levels of the education system. The qualitative, data-driven content analysis reveals that remote teaching provides beneficial opportunities for involving students’ everyday lives and families in craft education. However, challenges exist relating to the unequal distribution of materials, as well as technical and social resources at different levels of education and in various contexts. Our study also finds that remote teaching is more teacher-centred and task-oriented than classroom interaction. Online teaching facilities allow teachers to provide students with more individual feedback but make maintaining students’ peer interaction difficult. Although remote craft education was considered very challenging at first, teachers have managed to create useful pedagogical practices to be utilised in and beyond the era of the Covid-19 pandemic.
The EU’s Education Policy Response to the Covid-19 Pandemic: A Discourse and Content Analysis
Authors: Symeonidis Vasileios , Francesconi Denis , Agostini Evi
Published: October 2021

Following the severe impact of the Covid-19 pandemic on education systems in Europe, the EU has been called upon to provide a concerted response to the crisis in a context where member states provided their own diverse responses. Against this background, the aim of this article is to uncover and critically examine the EU’s education policy discourse and promoted narratives since the outbreak of the Covid-19 pandemic, and by doing so evaluate the EU’s response-ability for education recovery during the crisis. A conceptual framework has been devised to analyse the responsiveness of an international entity, such as the EU, based on organisational and neo-institutionalist theories. Data were collected through a combination of discourse analysis and computer-assisted content analysis, which was applied to official EU education policy documents published in 2020. The following categories emerged from the analysis process, indicating that the EU perceives education recovery as: “upskilling and reskilling”, “digital transformation” and “sustainable development”. The findings suggest a substantial continuation between the EU’s pre- and post-Covid-19 strategy in the education sector, and even an acceleration in the same direction, revealing a lack of real change in the EU’s response, which was focused predominantly on the economic and employability approach to education.
Lost Trust? The Experiences of Teachers and Students during Schooling Disrupted by the Covid-19 Pandemic
Authors: Jokić Zorkić Tijana , Mićić Katarina , Kovacs Cerović Tunde
Published: October 2021

This paper aims to help understand how relational trust between students and teachers embedded in the teaching-learning process unfolded during the emergency distance and flexible hybrid education in Serbia in 2020. It also identifies niches in student-teacher relationships that hold potential for repairing and building trust. For the student-teacher relationship to be trust-based and thus conducive to students’ learning and wellbeing, a consensus about role expectations must be achieved. As the Covid-19 crisis interrupted schooling and education, participants faced uncertainties and ambiguities in role enactment, and the cornerstones of relational trust were disrupted. In an effort to understand 1) the context in which trust was challenged, 2) the ways in which trust was disrupted, and 3) the opportunities for its restoration, we relied on a multi-genre dynamic storytelling approach to data collection and values analysis for data processing. A total of 136 students and 117 teachers from 22 schools wrote 581 narratives in three genres: stories, letters and requests. The analysis yielded 22 codes that allowed further understanding of how changes in structural and institutional conditions affected both students’ and teachers’ expectations of each other, and how incongruence of these expectations fed into feelings of helplessness for both students and teachers, disengagement from learning for students, and heavy workload and poor performance for teachers. In addition, the narratives account for positive outcomes when these expectations were met, and for opportunities for trust-building if students’ and teachers’ perspectives are brought to each other’s attention and negotiated locally. Finally, recommendations for restoring trust are given.

Published: October 2021

The article is devoted to the study of the operation of the container terminal of the Tashkent-Commodity station during the turnover of the container block-train. An organizational and technological model of the container turnover in the form of a network graph is considered, and the technological capacity of the terminal is calculated by modeling operations with containers in the form of a step-by-step algorithm. The resulting methodology makes it possible to predict the duration of the turnover of a block-train and is a kind of imitation of the Uzbek railway network from the point of view of launching a container block-train.Keywords: cargo transportation, admission,delivery, loading, unloading, container, terminal, block-train, algorithm
Plant phylogeny as a major predictor of flower visitation by nitidulid beetles, a lineage of ancestral angiosperm pollinators
Authors: Herrera Carlos M , Otero Carlos
Published: October 2021

Plant phylogeny sometimes predicts interspecific variation in pollinator composition better than floral features, and its predictive value seems to differ among major groups of insect pollinators. Earlier findings suggesting that pollination by Plant phylogeny sometimes predicts interspecific variation in pollinator composition better than gross floral features, and its predictive value seems to differ among major groups of insect pollinators. Pollination by beetles exhibits the strongest phylogenetic signal and the strongest phylogenetic conservatism, which is particularly intriguing given that beetles were probably the pollinators of early angiosperms. We examine in this paper the relationship between plant phylogeny and flower visitation by nitidulid beetles (Coleoptera: Nitidulidae), an old monophyletic group of flower specialists and pollinators of gymnosperms and angiosperms. Using quantitative data on pollinator composition for 251 plant species (belonging to 167 genera in 46 families) from well-preserved Mediterranean montane habitats from southeastern Spain, the following questions were addressed: Is pollination by nitidulids correlated with plant phylogeny in the large species sample studied, and if it does, which are the relative importances of plant phylogeny, floral characteristics, and environmental features as predictors of nitidulid pollination in the plant assemblage studied ? Nitidulids were recorded in flowers of 25% of the plant species considered. Their distribution was significantly related to plant phylogeny, being clustered on certain lineages (Ranunculales, Malvales, Rosales, Asterales) and remarkably absent from others (e.g., Fabales, Lamiales). None of the environmental (habitat type, elevation) or macroscopic floral features considered (perianth type and color, flower mass) predicted nitidulid visitation after statistically accounting for the effect of plant phylogeny. We theorize that nitidulid beetles use characters of plants that track plant phylogeny at least as deep as the early radiation of the eudicots, imaginably characters such as the chemical signatures of pollen.
An updated insect exclosure design for pollination ecology
Authors: Tetreault Troy , Aho Ken
Published: October 2021

Exclosures are a common method for quantifying the effects of animal pollinators on flowering plant species. However, a lack of standardized designs or clear descriptions of previously implemented exclosure designs decreases replicability in pollination studies and reduces scientific rigor. We summarized previous descriptions of pollination exclosure designs, and developed/tested a novel exclosure design in alpine environments on the Beartooth Plateau in northern Wyoming, USA. This exclosure design consists of a cylindrical internal wire frame, integrated ground stakes, and various mesh materials attached to the exterior. Exclosures on the plateau showed high efficacy in inhibiting insects from pollinating flowering plants, and nearly all of these exclosures remained functional throughout the time they were in place. Our updated exclosure design is effective, inexpensive, easy to produce, and widely applicable across differing ecosystems and experimental design types.

The purpose of this paper was to do a comparative evaluation of the skull of two species of lizards, the Komodo dragon (Varanus komodoensis) and the Green Iguana (Iguana iguana), by three-dimensional computed tomographic reconstruction. Images provided by this method give excellent anatomic detail of the skull. Therefore, essential differences in the configuration of the orbit and the lateral bones of the neurocranium were visualized in lateral and dorsal reconstructed images. The images obtained by tridimensional computed tomographic reconstruction can be a valuable diagnostic aid for the clinical evaluation of several head disturbances in lizards.Key words: computed tomography; 3D reconstruction; anatomy; skull; lizardsPRIMERJAVA LOBANJ KOMODOŠKEGA VARANA (Varanus komodoensis) IN ZELENEGA LEGVANA (Iguana iguana) S POMOČJO TRIDIMENZIONALNE RAČUNALNIŠKE TOMOGRAFSKE REKONSTRUKCIJEIzvleček: Namen prispevka je bil s tridimenzionalno računalniško tomografsko rekonstrukcijo opraviti primerjalno oceno lobanje dveh vrst kuščarjev, komodoškega varana (Varanus komodoensis) in zelenega legvana (Iguana iguana).

Developing intercultural competence: a model based on introducing a literary analysis in a foreign language classroom
Authors: Ibragimova Anfisa N. , Kadyrova Alina A.
Published: October 2021

This article is concerned with developing students' intercultural competence through teaching a literary analysis as a part of teaching foreign languages and linguistics in higher education. The objective of the research is to design a model of developing intercultural competence through a literary analysis in a foreign language class. Modeling was applied as the leading method of the research as it regards the process of IC (intercultural competence) development as a task-oriented and organized pedagogical process. The submitted didactic model should develop the IC through knowledge, skills, a system of values, reflection and positive attitude to the culture under study, so it includes such components as objectives, motivation, organization, content, and evaluation; it determines the pedagogical conditions, organization, teaching methods and tools that together provide the targeted result. The formative experiment introduced the model into practice in a foreign-language class at university and showed positive results in developing the students' intercultural competence. The model provides pedagogical support of the process of developing IC as a part of foreign language teaching and can be applied within language, literature and linguistics-related courses.

Authors: Sitdikova Farida Bizyanovna , Asmolovskaya Maria Vladimirovna
Published: October 2021

The article presents a study in the field of linguistic pragmatics and considers the implicitness problem with respect to the communication act. Extracting an impicature of an utterance is proved to be the main condition for successful speech act. The relevance of the article is determined by the fact that the implicitness problem has not been completely studied and still has a lot of aspects to explore. The classification of different kinds of implicatures supported by examples from fiction texts is given. Moreover, some statistic data relating to impicatures types and their frequency are provided. The article might be interesting for specialists developing problems of linguistic pragmatics, communication acts and implicitness.
Implicit predicativity of nominal sentences in russian and english languages
Authors: Bizyanovna Sitdikova Farida , Andreevna Kirpichnikova Anna
Published: October 2021

The article considers nominal sentences in Russian and English languages. This type of sentences have always been to seen as one-member sentences, but in the recent decades some researches have appeared claiming that they contain implicit predicativity, that is, they can be considered as two-member sentences at the level of semantics. The authors completely support this view and explore the way how one member sentences express predicativity using limited language means. The authors also provide the classification of nominal sentences with language examples in Russian and English and express the view that nominal sentences have different degrees implicit predicativity. Special attention is paid to the kinds of nominal sentences with highest implicit predicativity.
Phono-stylistic features of small prose by E. Canetti

Published: October 2021

Linguistics as the science of language, its social nature and functions, the laws of its functioning, historical development includes many sections that consider various aspects of language - first of all, sounds (phonetics, phonology), words (morphology), sentences (syntax) and values (semantics). One of these sections is phono-stylistics, the task of which is to study the sound aspects of speech, the sound organization of the text, and sound effects in a work of art. The phonetic means of stylistics are the frequency of phonemes, sound repetitions, sound reproduction, and rhyme use. The study of a work of art from the point of view of phonetics plays a special role insofar as the analysis of the use of phonetic means (melody, rhythm, tempo, tone, accent, rate of speech, the use of certain sounds) in a text, sound support, stylistic meaning of the subtext helps to reveal the ideological intention of the author and to comprehend the aesthetic and emotional depth of a work. The purpose of this article is to consider the phono-stylistic, or rather rhythmic-intonational, features of Elias Canetti's short prose; for convenience, we will use the term “miniature”, “story” in this article, recognizing certain conventions within this genre modification.

Published: October 2021

Perilla is a rich source of polyphenols, which exhibits antioxidant, anti-inflammatory activities, and a variety of biological effects. The effect of differential solvents on the polyphenols, flavonoids, rosmarinic acid (RA), antiinflammatory and antioxidant activities of perilla leaf require investigation. In this study, perilla leaf was extracted with 70% ethanol and sequentially fractionated according to the solvent’s polarity with hexane, dichloromethane, ethyl acetate, and water. Samples were subjected to the bioactive compound measurements. The antioxidant and antiinflammation nature of perilla was analyzed based on the scavenging effects on DPPH•, ABTS•+, O2•- and nitric oxide (NO), as well as FRAP assay, and determination of the inhibition effects on NO, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) production in the cell-based study. The results indicate that among all different solvents used for sequential fractionation, ethyl acetate (EtOAc) was most effective in the separation of anti-oxidative and antiinflammatory compounds in the perilla leaf extract. These properties can partly be due to the presence of polyphenols, flavonoids, and also RA. It can be demonstrated here that, the perilla leaf EtOAc fraction could be used as a natural active pharmaceutical ingredient for dietary supplements and nutraceuticals.

Breast cancer affect almost 1 in 8 women and it is highest in developed and developing countries. There are many drugs exist for the treatment of breast cancer, but still the incidence of mortality and morbidity are high among all cancer types in most countries. Even though the conventional therapies play a major role in the management of breast cancer, its complications are obvious and unavoidable. The newer targeted drug therapy came in place to reduce complications in some extent, but not fully. Hence, a review was aimed to analyse the efficacy and safety of newer anticancer drugs that approved for the treatment of breast cancer by US-FDA from 2017 to 2019. The Olaparib, Talazoparib, and Ribociclib are the newly approved drugs for the treatment of breast cancer during this review period. Among these new drugs, Olaparib and Talazoparib alone or in combination with other anticancer drugs considered as safe and efficacious. Patients with Olaparib or Talazoparib as monotherapy have median progression-free survival of 2.8 to 8.6 months longer and has 42-46% lower risk of death (P
