Student-Produced Video for Learning: A Systematic Review
Authors: Lam Jedidiah Zehuan , Yunus Melor Md
Published: March 2023

In this modern era, students learn in various ways, and thus, the learning methods should also change to suit them. Student-produced videos are one of the proposed methods. Therefore, this systematic literature review focuses on student-produced videos and their benefits to learning. This systematic literature review used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) review methodology. A total of thirty articles from 137 articles related to student-produced videos in learning were identified between the years 2018 and 2022. These articles were selected from Web of Science (WoS) and Education Resource Information Center (ERIC) databases. Based on the results, four benefits were identified: video production skills, creativity, collaboration, and a learning environment. Thus, this systematic literature review paper can benefit policymakers, educators, and learners looking to utilize and implement student-produced videos in learning.

Published: March 2023

This study investigates the utilization of Balinese cultural terms in the writing of English as a foreign language (EFL) students. It is intended to identify how the lexicons containing local values are used considering the translation procedures in the student’s mind. This qualitative research was conducted with ATLAS.ti software to visually present the connectedness of each lexicon with one another and to report the procedures of translation the students chose. When inserting the Balinese lexicons into their writing, the students involved in this study were still influenced by the concept of translation. With the translation procedures in mind, they applied transference, literal translation, functional equivalent, descriptive equivalent, and the combination of two and three procedures, namely, couplet and triplet, to be able to communicate their ideas involving the Balinese lexicons in their English writing. This study sheds some light on the application of translation procedures when students use local language terms in their foreign language writing. The students borrowed the local lexicons and gave an additional explanation to clarify their values. This finding indicates that having the concept of translation, and particularly the procedures of translation, can assist EFL students in broadening their knowledge of the existence of Balinese cultural terms as well as utilizing them by applying translation procedures to clarify the meaning of the terms in their writing to create communicative writing.
Discourse-Pragmatic Functions of Ya3ni in Najdi Arabic Interaction
Authors: Almossa Amereh I.
Published: March 2023

The Arabic discourse-pragmatic feature ya3ni occurs frequently in natural interactional settings. Several studies have reported that ya3ni (lit. ‘I mean/it means’) has developed a wide range of discourse-pragmatic functions in many spoken Arabic varieties such as Egyptian Arabic (Elshimi, 1992; 1993; Marmorstein, 2016, 2021a), Gulf Arabic (Owens & Rockwood, 2008), Libyan Arabic (Gaddafi, 1990), and Syrian Arabic (Alkhalil, 2005; Habib, 2021). Although the formal and functional variability of ya3ni has been documented in the literature, ya3ni has not been studied in the context of spoken Najdi Arabic. This paper examines discourse-pragmatic uses of ya3ni in Najdi Arabic (NA) in the interactional situation and how the functional variation is constrained by its turn position. A total of 376 ya3ni tokens were extracted from a corpus of five hours of audio-recorded dyadic natural conversations with twelve native speakers of NA. Drawing on the conversation analytic approach within a variationist framework, multiple discourse-pragmatic functions of ya3ni are attested. For interpersonal meaning, speakers recruit ya3ni to introduce assessment and minimise the effect of disagreement, whereas recipients use it to check their understanding. For the textual meaning, it can be used by speakers to introduce expansion and elaboration, explain intention, change the topic, sum up, and hold the floor.
Motivaciones y limitaciones de los médicos especialistas para hacer investigación clínica en un hospital de alta complejidad en Colombia
Authors: Montoya-Ochoa Lilliana María , Yepes-Delgado Carlos Enrique , Villegas-Molina Juan Pablo , Pérez-Ricci Ximena Alejandra
Published: March 2023

Introducción: los médicos clínicos investigadores son necesarios para el desarrollo de la literatura médica sobre la cual se soporta el ejercicio clínico, y así contribuyen a la calidad del acto médico y del sistema de salud. Se requiere mayor investigación de sus motivaciones y barreras para hacerlo.
Objetivo: describir las motivaciones y limitaciones que los médicos especialistas enfrentan para poder convertirse en investigadores en un hospital privado de alta complejidad en Colombia.
Materiales y métodos: se realizó un estudio hermenéutico con técnicas de la teoría fundamentada, con 30 entrevistas semiestructuradas realizadas a 20 médicos especialistas del Hospital Pablo Tobón Uribe. El análisis utilizó codificación abierta y se agruparon los códigos en categorías descriptivas, al identificar propiedades y dimensiones de la teoría fundamentada. La codificación axial permitió describir las tensiones entre las motivaciones y las limitaciones para investigar.
Resultados: se identificaron como motivaciones para investigar el reconocimiento y el prestigio profesional e institucional gracias al respaldo del Hospital, además de la remuneración económica adicional, tanto por estudios de la industria farmacéutica como propios. Como barrera se destacó la precaria formación en investigación, que se suma al ambiente competitivo entre colegas y a las tareas administrativas y protocolizadas de los estudios, lo cual que genera desinterés.
Conclusiones: a pesar de facilitar y respaldar el desarrollo de la investigación en esta institución, en el contexto del país aún no hay una fuerte cultura investigativa que promueva e incentive a los profesionales de la salud a desarrollar investigación de manera independiente o institucional, pues con frecuencia las limitaciones sobrepasan las motivaciones para hacerlo.

Published: March 2023

Environmental Impact Assessment – EIA, makes a preventive and corrective study possible to avoid damages resulting from anthropogenic activities. Different methodologies are used taking into account criteria at the discretion of the professional, and the application of qualitative and quantitative parameters, particularly for water resources, the proposed methodologies and tools that allow a deep analysis to be carried out are limited. In this sense, the goal of this study is to design a tool for Environmental Impact Assessment applied to the Vado-Castro sector by means of Transparency Overlay Methods, Leopold, and Battelle-Columbus. The development of these methods was performed based on a diagnosis and monitoring of the water resource, articulating the characterization and quantification of the environmental impacts generated by economic, mining, agricultural and livestock activities. Finally, a unified standard methodological tool was formulated, which is applicable to the water resource sector and considers all the necessary criteria and attributes when carrying out a comprehensive EIA, as it is possible to demonstrate its applicability to the case of the Chicamocha River tributary area. The results obtained will allow this research to be used as a source of consultation for academic and technical studies that need to assess the effects of the water resource, in addition to being a tool with projection of application to any other body of water.

We report the development of optical fibre resonant scanner that was developed using two multi-mode optical fibres that are attached side-by-side, producing a cantilevered optical fibre scanner. The optical fibre is mounted on photodiode and a small piezoelectric disk using polymer. The piezoelectric disk is driven with a sinusoidal signal that will then vibrate the mounted optical fibre, producing a single axis scan line. This paper reports on experimental detection of the back-scattered signal through dual-numerical aperture conFigureuration and identification of fibre position from a single scan line with respect to the optical reflections from the apertured reflector. The apertured reflector used was a brass metal with 1 mm of diameter that is placed before the imaging lens as a mechanism to differentiate the position of scan line. The single scan was obtained at its maximum length of 4.8mm with resonant frequency of 2.033kHz. The back-scattered signal from a target object is coupled back into the cladding of the optical fibre. The cladding mode is then stripped and detected by photodiode. The back scattered signal from the aperture is used to differentiate the position of fibre between the aperture and the target object itself. Differences in the position of the slots resulted pulses with different height and width, allowing the two backscattered signals to be distinguished. The experimental result is verified and compared with the theory back-scattered signal produced by such scanner.

Micropowder injection moulding (μPIM) is an ideal alternative for miniaturization of parts because of its ability to produce complex micro-geometries at low manufacturing cost. Utilizing bimodal powder mixtures in feedstock can increase packing density and densification of parts fabricated via μPIM. This study investigated the feedstock consists of nano-micro 316L stainless steel powder-and polyethylene glycol-based binder system. The flowability of different feedstocks was evaluated using rheological parameters, including critical powder volume concentration (CPVC), melt viscosity, activation energy, and rheological index. Results showed that mixing nanopowders with micropowders increases CPVC from 67.66 vol.% (pure micropowder) to 78.33 vol.%. The nano-micropowder feedstock showed viscosity below 45 Pa·s and shear rate in the range of 102 s−1 to 105 s−1, which are suitable for the μPIM process. The determined flow index values ranged from 0.25 to 0.76, and the reduced n values at high temperature with the addition of nanopowder indicated a possible increase in shear-thinning behavior. A defect-free microsample was obtained at an injection temperature of 85°C with sintering at 1200°C. Using the nano–micro bimodal powders, the hardness of the obtained samples also increased from 182 HV to 221 HV, with strength of 501 MPa, which is higher than that of the sample obtained with the use of micropowder only (435 MPa).
La imagen de la mujer en las campañas institucionales andaluzas sobre igualdad de género. Un estudio de las notas de prensa
Authors: Hernández Flores Nieves
Published: March 2023

Las notas de prensa publicadas en la página web del Instituto Andaluz de la Mujer (IAM) para difundir campañas en torno a la celebración del 8 de marzo (Día Internacional de la Mujer) son un subgénero de discurso institucional que permite análisis metadiscursivos, pues en él se puede identificar la ideología dominante en torno al tema de la igualdad de género en este marco institucional. En este trabajo se analizan notas de prensa durante los dos períodos de gobierno en Andalucía (socialdemócrata y liberal-conservador) de los últimos 8 años. Se analizan los temas tratados, las representaciones de los actores sociales involucrados (el IAM, como emisor, y las mujeres andaluzas, como grupo social objeto de las campañas); los roles sociales asignados y, finalmente, la situación de la imagen social de estos grupos, así como los comportamientos de cortesía y descortesía que produce este discurso. El marco teórico es el Análisis Crítico del Discurso y el Análisis Social del Discurso. El análisis cualitativo muestra que la igualdad es la principal base ideológica, pero los valores que la definen cambian en los dos períodos, con un enfoque en la justicia social y la emancipación de la mujer en el período socialdemócrata, y en la productividad en el período conservador. Se producen efectos de cortesía, pero también en ocasiones de descortesía cuando la institución adopta un papel superior hacia la mujer, o cuando antepone sus objetivos políticos a la consecución del propósito (la igualdad).

THE CONCEPT OF THE WORLD TREE IN THE UKRAINIAN ETHNO-CULTURAL TRADITION AND IN THE ANCIENT INDIAN CULTURE
Authors:   Taras Shevchenko national University of Kyiv, SOROCHUK Liudmyla
Published: March 2023

ThearticleexaminestheconceptoftheWorldTreeas a dominantelementintheUkrainianethno-cult Abstract. The article examines the concept of the World Tree as a dominant element in the Ukrainian ethno-cultural tradition and the culture of Ancient India. The image of the World Tree is the basis of archaic culture and is represented through the prism of mythology and the worldview system of our ancestors. Attention is focused on the fact that the World Tree reflects an ordered model of the universe in space and time, which determines the organization of the cosmic space and has the corresponding symbolism. In many cultures of the world (the proposed work focuses on the culture of Ancient India), the World Tree represents the unity of three worlds - the heavenly (the world of Gods), the earthly (the world of people) and the afterlife (the world of ancestors). The World Tree (Tree of Life) also has temporal symbolism, that is, the roots are the past, the trunk is the present, the crown is the future. In the Ukrainian ethnocultural tradition, the image of the World Tree is characteristical for the mythological consciousness of our ancestors and embodies the universal concept of the world, which is reflected in various manifestations (heavenly tree, tree of life, ancient tree), as well as in transformational images (world pillar, world mountain, paradise tree, willow). Using the examples of folklore texts, it is proved that the World Tree means a sacred point of origin, functioning as an important sphere of fertility cult in various rites of the calendar cycle and family rites. Attention is focused on the position of the universality of the image of the World Tree in the ancient myths of ancient India, which is embodied in the world axis, temple, tree of life, tree of knowledge and, what is interesting, in the image of the great "inner man" that lives inside each individual. In Indian culture, over the centuries, accumulated knowledge about the inner spiritual world of a person, combined with a perfect physical body, made up a whole system of teaching - yoga. In a broad sense, this concept includes a combination of spiritual, psychological and physical practices that were originated in Hinduism and Buddhism. Therefore, the concept of the World Tree acts as a sacred, fixed symbol almost everywhere and had a powerful influence on the formation of the mythological worldview.
THE ANTIHUMAN MEANING OF THE RUSSIAN "SPECIAL OPERATION OF LIBERATION": AN ATTEMPT TO CONCEPTUALIZE THE ACTION OF EXTERMINATION OF UKRAINIANS WITHOUT RESTRICTIONS
Authors:   Ivan Cherniakhovskyi National Defense University of Ukraine, Kyiv Ukraine, TSIURUPA Mykhailo
Published: March 2023

Any war, the war of aggression in particular, brings countless suffering: There is nothing worse than it, says the captured, the character of the novel by J. -P. Sartre "Iron in the soul", and it seems "chameleon", reminded Karl Clausewitz of the appearance of its new modules, always changes its color, i.e. nature. Today, when the first socio-cultural shock caused by the unprovoked attack of the Russians on Ukraine faded, it became clear that the so-called humandimensional side of the war, as well as the political side, has radically changed, "noble wars by rules" have gone in the past. With all the greed of destruction and suffering in the wars of the past, there was a rational aspect – to force the enemy’s troops to suffer defeat and take advantage of the “fruits of victory” on the seized territory. Aggressive attack by Russian federation on Ukraine since February 2022 in its anti-human essence surpassed all previous wars, because the weak regulators, which had the aim to limit brutal violence, were rejected. They refer to humanitarian law, noble morale, universal conscience, rules and traditions of the conduct of wars, according to which civilians and buildings are not the object of attack. The targeted murder of people for their belonging to Ukrainians, the torture of children, not only of the prisoners and hostages, the shooting of priests and doctors (not combatants), the threat to use nuclear weapons have shown the meanness of the aggressor, who as T. Adorno noted, established "the pure identification of Ukrainians and death in torment". Philosophical logical and rational tools do not allow expressing the moral depth of existential threats, so it is better to use symbolic form. In particular, the symbol "Auschwitz" was used by the culturologists and philosophers of Europe after the end of the Second World, and now the names of the Ukrainian cities "Buсha", Mariupol (Azovstal) are being used to mark the Ukrainian unrivaled fight against the aggressors and the impersonal pain of thousands people tortured by Russian soldiers. The military and political authorities of the aggressor state and its silent performers have given birth to the “banality of evil” characteristic of the Nazis, fascists of Europe and the East’s militarists in the Second World War, which lead to the millions of murders and the transformation of a persona into the smoke of Auschwitz. The new symbols "Mariupol" and "Azovstal" engraved the unprecedented cruelty and anti-humanity of the enemy, as well as the imminent punishment of his crimes through a common human judgment, the operation of the International Criminal Tribunal, the revenge of a just and comprehensive resistance to Russian invaders.

This work is devoted to the study of new iterative algorithms for solving variational inequalities in uniformly convex Banach spaces. The first algorithm is a modification of the forward-reflectedbackward algorithm, which uses the Alber generalized projection instead of the metric one. The second algorithm is an adaptive version of the first one, where the monotone step size update rule is used, which does not require knowledge of Lipschitz constants and linear search procedure.
Magnitude and Slip Scaling Relations for Fault-Based Seismic Hazard
Authors: Shaw Bruce E.
Published: March 2023

Scaling relations play an important role in fault-based seismic hazard estimates. Scaling relations impact estimates of the sizes and rate for a given fault area. Here, we examine which relations are the most useful for these estimates and issues that arise. These include the depth of large event ruptures, transient deepening of seismicity following large events, difficulties in using classical continuum exponent fits, and the importance of large event asymptotics. A new analysis of land-based data calls into question nonspecific exponent fitting, which is a standard practice. We show a dependence on the lower and upper cut-off magnitudes in the data in the best-fitting slope parameter relating magnitude to log area with this approach. We show as well a dependence on assumed data uncertainties. These sensitivities make using this quite standard approach very problematic. Based on this evidence and other factors, we propose recommendations for the minimal branch sets, which preserve epistemic uncertainty for use in fault-based seismic hazard estimates.
An Attempt to Determine the Magnitudes and Epicenters of Significant Historical Earthquakes in the Pannonian Basin
Authors: Varga Peter , Győri Erzsébet , Fodor Csilla , Timár Gábor
Published: March 2023

This study aims to determine the epicenters and magnitudes of pre-instrumental historical earthquakes in the Pannonian basin based on contemporary sources and the literature that recorded the effects, damage, and accompanying events. A local intensity value for a given place was estimated only if it could be determined based on contemporary data. Using intensity data from different locations, the position of the hypocenter and magnitude of the historic earthquakes were calculated using an empirical equation. The epicenter positions were compared with the spatial distribution of liquefaction phenomena, foreshocks, and aftershocks, for which data were available. Finally, the set of historical Mw≥5.5 events is supplemented with locations of instrumentally measured earthquakes of similar sizes, and the relationship between the location of the resulting seismic events and the main tectonic structures of the Pannonian basin is investigated. Our investigation suggests that the location of the earthquake epicenters is not linked to known major tectonic structures and that the earthquake activity in the Pannonian basin may be higher than previously thought.

This work compares different thicknesses of vitreous enamel coating applied to welded joints. Low-carbon steel Kosmalt E300T was used as a base material. The MAG welding method was used for all samples. Metallography was performed to compare the thickness of the coating formed on the machined and unmachined surfaces of the weld. SEM analysis focused on the substrate/vitreous enamel coating interface. The results show that the high thickness of the vitreous enamel coating that occurs in unmachined weld joints significantly decreases the properties of the enamel coating. In comparison, the machining of the weld surface contributes to the quality improvement of the vitreous enamel coating.

Teacher transfers and the disruption of Teacher Staffing in the City of Sao Paulo
Authors: Elacqua Gregory , Rosa Leonardo
Published: March 2023

This paper analyzes preferences for certain school attributes among in-service teachers. We explore a centralized matching process in the city of Sao Paulo that teachers must use when transferring schools. Because teachers have to list and rank their preferences for schools, we can estimate the desirability of school attributes using a rank-ordered logit model. We show that the schools distance from the teachers home, school average test scores, and teacher composition play a central role in teacher preferences. Furthermore, we show that preferences vary according to teacher characteristics, such as gender, race, age, and academic subject.
Signaling Specific Skills and the Labor Market of College Graduates
Authors: Busso Matías , Montaño Sebsatián , Muñoz-Morales Juan S.
Published: March 2023

We study how signaling skills that are specific to college majors affect labor market outcomes of college graduates. We rely on census-like data and a regression discontinuity design to study the impacts of a well-known award given to top performers on a mandatory nationwide exam in Colombia. The award allows students to signal their high level of specific skills when searching for a job. These students earn 7 to 12 percent more than otherwise identical students lacking the signal. This positive return persists five years after graduation. The signal mostly benefits workers who graduate from low-reputation colleges, and allows workers to find jobs in more productive firms and in sectors that better use their skills. We rule out that the positive earnings returns are explained by human capital. The signal favors mostly less advantaged groups, implying that reducing information frictions about students skills could potentially shrink earnings gaps. Our results imply that information policies like those that formally certify skills can improve the efficiency in talent allocation of the economy and, at the same time, level the playing field.
Could the lake ecosystems influence the pathogenicity of the SARS-COV-2 in the air?
Authors: Boratyński Janusz
Published: March 2023

During the first 200 days of the Covid-19 pandemic in Poland, lower morbidity and mortality due to SARS-COV-2 infection were recorded in three regions covered by many small and large lakes (West Pomerania 5.8 deaths/100 000 population, Warmian and Masurian 7.6 deaths/100 000 population, Lubusz 7.3 deaths /100 000 population, compared to Poland average of 16.0 deaths/100 000 population). Moreover, in Mecklenburg (Germany), bordering West Pomerania, only 23 deaths (1.4 deaths/100 000 population) were reported during the same period (Germany 10 649 deaths, 12.6 deaths/100 000 population). This unexpected and intriguing observation would not have been noticed if SARS-CoV-2 vaccinations were available at that time. The hypothesis presented here assumes the biosynthesis of biologically active substances by phytoplankton, zooplankton or fungi and transfer of these lectin-like substances to the atmosphere, where they could cause agglutination and/or inactivation of pathogens through supramolecular interactions with viral oligosaccharides. According to the presented reasoning, the low mortality rate due to SARS-CoV-2 infection in Southeast Asian countries (Vietnam, Bangladesh, Thailand) could be explained by the influence of monsoons and flooded rice fields on microbiological processes in the environment. Considering the universality of the hypothesis, it is important whether the pathogenic nano- or micro particles are decorated by oligosaccharides (as in case of the African swine fever virus, ASFV). On the other hand, the interaction of influenza hemagglutinins with sialic acid derivatives biosynthesized in the environment during the warm season may be linked to seasonal fluctuations in the number of infections. The presented hypothesis may be an incentive to study unknown active substances in the environment by interdisciplinary teams of chemists, physicians, biologists, and climatologists.

Published: March 2023

Dysphagia is defined as the difficulty to swallow food and liquid. Pureed food is commonly used in dysphagia management. For patients with dysphagia, a commercially available thickener is usually added during the preparation of pureed food to impart desired consistency which aids in reducing the risk of choking. However, high costs and limited availability of commercial thickener are burdens for some patients. Besides, the foods prepared by the commercial thickener also have consistent viscosity problems. Therefore, the use of instant pureed food has been proposed as an alternative solution for these shortcomings. This study was designed to evaluate the suitability of starch and gum as a thickener in instant pureed rice porridge for patients with dysphagia using rheological and sensory parameters. The experiments were then divided into two main sections: (1) analyses on rice porridge powder and (2) analyses on reconstituted rice porridge. Instant pureed rice porridge was developed for patients with dysphagia according to the framework outlined by the International Dysphagia Diet Standardisation Initiative (IDDSI). Overall, this study has successfully developed instant rice porridge that was suitable for consumption among patients with dysphagia and was proven to be acceptable through sensory study. Xanthan gum was shown to have the greatest potential to be used as a thickener in instant rice porridge. The success of the incorporation of xanthan gum into instant rice porridge can be a cheaper and more convenient option to the existing commercial thickener for dysphagia management.
Gerhardtite and Likasite from Rodingites of Bazhenovsk Ophiolite Complex (Middle Urals)

Published: March 2023

The results of studying nitrate mineralization in rodingites of the Bazhenovsk ophiolite complex located on the eastern slope of the Middle Urals are presented. Rodingites are metasomatic rocks of garnet-pyroxene composition that replace gabbroid and diorite dikes that cut across the Bazhenovsk ultramafic massif. Some apogabber and apodiorite rodingites have in turn been altered by hydrothermal fluids, probably generated by an underlying granite intrusion. Chalcocite is the main sulfide mineral in hydrothermally altered rodingites. It forms clusters of irregular shape, up to 1 cm in size. Visually, chalcocite is often covered with greenish and bluish films, which, upon detailed study, turned out to be an aggregate of chrysocolla, dolerophanite, langite, connellite, and mitscherlichite with the presence of nitrate mineralization. Copper nitrates are represented by gerhardtite and likasite, the latter mineral apparently developing after the former. For both minerals, the data of X-ray electron probe analysis and IR spectroscopy are given, and the morphology of their aggregates and individuals is also shown. In addition, X-ray diffraction data for gerhardtite are given, since it has a dimorphic analogue – rouaite. The formation of nitrate mineralization, in our opinion, is of natural origin, since mantle rocks are a source of nitrogen.
The Influence of the Deep Position of the Roof of the C2b Formation and Salt Swally on the Production Capabilities of Wells in the Left-Bank Part of the Astrakhan Gas Condensate Field

Published: March 2023

The construction of horizontal wells requires a more accurate prediction of the filtration and reservoir properties of the reservoir for operational correction of their trajectory. The practical significance and relevance of the work consists in substantiating the possibility of the fullest realization of the potential of production wells when drilling new areas on the Left Bank of the Astrakhan gas condensate field. The purpose of the study is to identify the correlation dependencies of watering zones and low porosity and permeability properties on geological factors and to form recommendations for the horizontal wells drilling. The watering of wells is analyzed depending on the position of drilled wells on the structural surface of the productive reservoir C2b, the duration of the period of "waterless" operation of wells, the period of watering and well operation. The features of the location of zones with low porosity and permeability properties of productive deposits are studied. According to the results of the conducted research, definitely: the high value of the water-gas factor and the rapid watering of production wells is due to the high opening marks of the productive horizon (above -3850 m) and zones of vertical fracturing; zones with low porosity and permeability properties of the productive reservoir C2b are confined along the roof of the salt strata P1kir to the deepest areas of salt swally. The following recommendations on the drilling of wells for the fullest realization of their potential have been formed: 1) in areas with a high or low location of the roof of the Bashkir horizon, it is advisable to drill wells with a horizontal profile; 2) when conducting horizontal wells in salt swally and getting into the zones of low porosity and permeability properties during the opening of the productive reservoir, it is necessary to consider the possibility of changing the azimuth in the direction of the side of the swally.

This study focuses on the potential of harnessing the power of the local Eastern Orthodox religious teachings in creating a socially sustainable glocalized digital transformation for Romania. First, we investigated within the scientific literature the ways religion might impact social action, and where does spirituality intersect with digitalization. Second, we devised a questionnaire with items targeting religious styles and the perception of digitalization during the pandemic and in the foreseeable future along with inquiring about which institutions should get more involved in directing digital development. The sample was constituted of 170 adult residents from Bucharest and Constanta urban areas, most of them having graduated from university, with the sample being balanced between the engineering domains and the humanities domains of study. Thirdly, we employed statistical data analysis in order to explore differences in perception of risks, benefits, and in the desired action towards the digital transformation, between the different flavours of spirituality and religiousness. The aim of the study is to obtain valuable insights for creating a bridge between spiritual preachers, digital policymakers, and the civil society, driving development towards spiritually and economically sustainable goals, for a conscious society and a healthy environment.

The paper is an exposure to the latest practices of questioning in teaching and learning math (TLM) on the basis of psychological-semiotic approach. Emphasis is placed on the degree of semantic support of the expected answer when formulating educational questions. The paper explored: whether teachers are able to distinguish between types of questions and to use them in sync with didactic purpose; what types of questions teachers consider to be the most effective; what factors influence this process. To achieve these goals, survey-based research was conducted among 173 high school mathematics teachers across Ukraine. The research proved that, in their majority, teachers are able to correctly distinguish among the types of the questions offered. According to the teachers, questions with full semantic support for the answer are less useful in TLM. The study showed teachers’ lack of ability to identify the goals of the questions. There has been revealed a gap between the teachers’ attitude to the expedience of using questions with several possible answers and the practice of their implementation in TLM. The study yielded 35 variables characterizing the current status of the problem. They were optimized to 13 factors. It was stated that questioning should comply with the content of educational material, and the questions formulated with the use of topical vocabulary known to the students are viewed as most cost-effective. The research revealed the significant impact of the number of questions that teachers or students ask. The factor of primary importance appears to be that of time.
