Authors: Luwih I Made , Sudarsana I Ketut
Published: February 2022

The study aimed to determine the narrative structure in Ni Diah Tantri’s story and its Hindu religious teachings. Data collection in this study used a literature study. Several techniques carried out data analysis in this study. These were descriptive techniques, qualitative techniques, interpretation, checking the data validity, presenting data (data display), and concluding (verification). The study results show that the teachings contained in the story of Ni Diah Tantri were a form of tendency from the author, which is very useful for readers. The Hindu religious teachings in the story of Ni Diah Tantri consist of self-control, especially lust which is influenced by the thoughts of Sang Prabhu Eswaryadala. The next teaching was Ni Diah Tantri’s teachings of love who truly sympathize and her love for his father so that Ni Diah Tantri is willing to be handed over to Sang Prabhu Eswaryadala. Last, the teachings of loyalty from Ki Patih Bandeswarya to Sang Prabhu Eswaryadala. Ki Patih Bandeswarya’s loyalty to Sang Prabhu Eswaryadala was manifested by Ki Patih’s obedience to the king’s orders to offer beautiful girls every day for marriage.

Published: February 2022

Problems that often occur in the use of solar panels are the efficiency of solar panels and monitoring of solar panel generating systems. Monitoring of the output parameters of solar panels is very necessary to assess the performance and efficiency of a solar panel in real environmental conditions. Internet of Things (IoT) can make devices communicate with each other such as sending and receiving data. A monitoring system based on a wireless sensor network was created to make it easier to get direct and real time information on the output parameter data of the solar panels. The research objective is to create a monitoring system on a solar panel using Visual Basic and Blynk applications. This system is designed to determine the output parameters of the solar panel in the form of current, voltage, light intensity, and position which are processed directly and displayed in tables and graphs in Real Time conditions. The use of logger data in this monitoring system is very important. From the results of tests carried out on this monitoring system, the system is able to record and read the output parameters regarding the resulting current and voltage data as well as light intensity and the position of the solar panels. Information about measurement data from each sensor will be stored in the database and can be obtained directly through an excel spreadsheet.

Authors: Ojo Oluwaseun , Adeleke Kehinde , Ajayeoba Abiola , Bello Kamaldeen
Published: February 2022

Development of a prototype inverter powered baking oven was carried out and performance was evaluated to determine its efficiency. The oven was designed and fabricated with an outer dimension (506 mm length x 506 mm width x 506 mm height) made up of mild steel and inner dimension (436 mm length x 436 mm width x 436 mm height) made up of stainless steel and used fiber glass as an insulator. The materials for fabrications were locally sourced and served as alternative for baking, roasting or boiling using electrical recharged power in case of power failure. The prototype inverter baking oven operates on the principle of electrical resistance and 0.147?/W was obtained as the resistance of the heating element. The performance evaluation revealed the baking efficiency of the oven to be 94.29 %, 75 % and 66.7 % for bread, plantain and fish respectively, the maximum temperature of 160?C, 180?C and 200?C were recorded. Capacity of the baking oven was determined to be 6 loaves of bread per tray/batch. With practical determination and comparison made with other work, a prototype inverter powered baking oven can be adopted for domestic and industrial purpose depending on the production plans and the layout.
Brief Notes on The Possibility of Copying Qubits in Quantum Systems
Authors: Grigoryan Artyom , Agaian Sos
Published: February 2022

Copying the quantum states is contradictory to classical information processing since the fundamental difference between classical and quantum information is that while classical information can be copied perfectly, quantum information cannot. However, this statement does not rule out the risk of building a device that can reproduce a set of quantum states. This paper investigates the naturally arising question of how well or under what conditions one can copy and measure an arbitrary quantum superposition of states. The CNOT and XOR operation-based quantum circuit is presented that exhibits entanglement of states and allows for measuring the doubled qubits.

Authors: Aidek Ahmad , Amr Zuhair S. , Abu Baker Mohammad
Published: February 2022

The current distribution of the Persian squirrel (Sciurus anomalus) in Syria is described based on recent observations. The species distribution extends along the coastal mountains from the vicinity of Kasab in the extreme northwest of the country, along the mountains of Lattakia and Tartus, reaching the vicinity of Damascus in the southwest, with the highest situated records from the Tartus area. Threats including hunting, trading, habitat degradation, and conflicts with local people are outlined.
Energy saving in day-roosting female Myotis emarginatus during reproduction (Chiroptera: Vespertilionidae)
Authors: Spitzenberger Friederike , Weiss Edmund
Published: February 2022

From May to June 2012, we studied the behaviour of day-roosting reproductive female Geoffroy’s bats in a maternity roost in eastern Burgenland (Austria) which is under surveillance from 2011 till to date. By using a remote-controlled infrared-illuminated video camera, we conducted six weekly sessions of direct observation and instantaneous scan sampling, each lasting 16 hours. Based on a total of 384 sampling sessions, we quantified the amount of time adult females spent in the activities resting, alert, grooming and relocating during pregnancy and lactation. Ambient and roost temperatures were recorded hourly, the numbers of individuals returning to the roost in the mornings were registered constantly by using an infrared light barrier. Over the entire study period, all bats arriving in the maternity roost in the morning formed immediately a single huddling cluster. As a rule, this cluster was large, multilayered, three-dimensional and tight. It did not change in size and form until the onset of pre-emergence activities. It consisted of an interior part in which about 50% of all bats roosted and the periphery consisting of those bats which had not succeeded in entering the interior. Over the entire diurnal stay in the roost, resting – which causes the least energy output – was the predominant behaviour of all roost mates. Significant differences were found, however, in the amount of time allocated to some activities by bats occupying different positions in the cluster. While bats in the interior of the cluster spent the estimated 90–95% of the entire day-roosting period resting, bats on the periphery spent only 57–73% resting. The average percentage of time allocated by peripheral bats to grooming decreased from 27% in the first week to 19–13% in the following weeks of pregnancy and stayed at 16% during the two weeks of lactation. The mean percentages of being alert and of relocating ranged between 7–10% and 4–7%, respectively. During the last two weeks of pregnancy and the two weeks of lactation, roost temperatures, daily colony size and reproductive states did not influence the huddling behaviour significantly. However, activities performer in the first and second week were probably influenced by unrest due to colony formation after the return from hibernation (week 1) and by cold ambient temperatures during the week 2. Our study supports the hypothesis that the short duration and notable timing of reproduction typical for Myotis emarginatus (Spitzenberger & Weiss 2020) is achieved by maximal energy saving through continuous huddling in a large, three-dimensional, multilayered and tight cluster over both the entire day-roosting and entire reproductive period, differences in the behaviours of bats located in the interior and on the periphery of the cluster and lack of social interactions between roost mates.

First of all, we, the editors, need to apologize for the delay in this year’s publication. The editorial team this year has been fighting against a number of issue and we want to express our sorrow to those all over the world who have lost those most beloved ones in this COVID-19 Pandemia. Let’s hope that this year will be better. In relation to this volume, we had a large amount of rejections since our interest is to improve the quality of the journal in just about two years including a much earlier publication date. Thus, this year we will be accepting papers until June 30. We understand this may limit the number of incoming papers, but we definitely will jump further into a higher quality journal that puts Encuentro Journal in the international place that it really deserves. Six articles published in this issue cover three main areas of interest: first, language learning and methodology are in focus; next, new approaches to improve English writing and oral skills. Finally, the last section concentrates on the attitudes and perception of teachers about the English lessons in foreign education systems and on translation studies.
Semantics of Declarativity in German Political Discourse Based on the Example of the Phrase “gute Politik”
Authors: Степанова М.А.
Published: February 2022

В статье анализируется семантика декларативности в немецком политическом дискурсе на примере словосочетания “gute Politik" с позиций функциональной и когнитивной лингвистики, семантики и дискурсивной прагматики. Такие прилагательные, как “gut”, несмотря на статус семантических универсалий, не всегда однозначны, способны к модификации смысла в контексте и в свете конкретных речевых стратегий, а именно к расширению или утрате первоначального значения в зависимости от намерений говорящего и восприятия читателя/слушателя. Метод семантического поля позволяет не только описывать лексические значения, но и заглянуть глубже во внутреннюю структуру понятия. Пересекаясь с функционально-речевым полем, семантические признаки уступают место прототипическим признакам, которые определяют толкование и приоткрывают языковую картину мира.

The article analyses semantic aspects of declarativity in German political discourse as exemplified by an expression used by German chancellor Angela Merkel. The phrase “gute Politik” (engl. “good policy”) is analysed from the perspective of functional and cognitive linguistics, semantics and discourse pragmatics. Adjectives like “gut” (engl. “good”) are considered to be semantic universals, but they appear to be not always monosemantic, can modify meaning in some context through the lens of specific communicative strategies, can extend or lose their original meaning depending on the intentions of the speaker and the perception of the listener. The semantic field method can be used not only to describe lexical meaning. It crosses the functional field of speech, some semantic features give place to prototypic features, which determines interpretation, and reveal a certain linguistic world image.
GANDHIJI’S PHILOPSHY OF HEALTH: TRADITIONAL MEDICINES, FASTS AND DIETARY CHANGES
Authors: Lohar Asmbanu
Published: February 2022

No single person is more directly associated with India and India’s struggle for independence than Mohandas Karamchand Gandhi. His name has become alternative to the struggle for human equality, dignity and freedom. There is no match for Gandhi in sensualizing the temperament of Indians during colonial period and formulating freedom strategies accordingly. Highly versatile as he was, he influenced every aspect of Indian life including social, economic as well as cultural. By his observation and experiments with various strands of life, he developed his idiosyncratic vision about various spheres of human life. One of these visions was about human health including diseases, medicines and therapies. He conveyed this vision through the medium of his writings including his autobiography, letters and various books. His Views on diseases – Physical, mental and social, reasons of illness, remedies including fasts, dietary changes and uses of natural substances as well as on various medicinal systems are as relevant in today’s life as are his politico-social ideas. Gandhi’s guide to health needs to be emphasized much more than it has been by researchers to reap its maximum benefits.
NEGATIVE IMPACTS FROM DISRUPTION OF ROAD INFRASTRUCTURE ELEMENT PERFORMANCE ON DEPENDENT SUBSYSTEMS: METHODOLOGICAL FRAMEWORK
Authors: Rehak David , Patrman David , Foltin Pavel , Dvořák Zdeněk , Skrickij Viktor
Published: February 2022

The critical infrastructure system is determined by subsystems essential for the functioning of the state (such as energy, transport, and emergency services). Disruption to the function of these subsystems would have serious effects on state security, the state economy, and the provisioning of the inhabitants’ basic human needs. Links connect these subsystems (i.e., sectors, subsectors, and elements), and these links ensure that certain subsystems are integrated into each other. Their interactions are derived from the type and intensity of the mutual link. The interlinked subsystems can thus be divided into influencing and dependent ones. The aforementioned mutual links in the critical infrastructure system allow, amongst other things, the spread of impacts of disruptive events amongst the subsystems via cascading effects. Disruptions to the performance of an influencing subsystem may have negative effects on a dependent subsystem, resulting in the spread of cascading effects in the critical infrastructure system. Such effects are often difficult to predict, which reduces the responsiveness of the dependent subsystems. Road transport is one of the most significant influences on critical infrastructure subsystems. For this reason, the article focuses on an indication of the negative effects of disruption of road infrastructure elements on dependent subsystems. The article describes the role of road infrastructure in the context of the critical infrastructure system. Defines the dependent subsystems of road infrastructure, categorises the negative effects, and presents a possible approach to assessing the adverse effects of disruption road infrastructure performance on dependent subsystems.
Class I Methanol Masers Related to Shocks Induced by Bar Rotation in the Nearby Starburst Galaxy Maffei 2
Authors: Chen Xi , Yang Tian , Ellingsen Simon P. , McCarthy Tiege P. , Ren Zhi-Yuan
Published: February 2022

We report the detection of class I methanol maser at the 36.2 GHz transition toward the nearby starburst galaxy Maffei 2 with the Karl G. Jansky Very Large Array. Observations of the 36.2 GHz transition at two epochs separated by ∼4 yr show consistencies in both the spatial distribution and flux density of the methanol emission in this transition. Similar to the detections in other nearby starbursts the class I methanol masers sites are offset by a few hundred pc from the center of the galaxy and appear to be associated with the bar edges of Maffei 2. Narrow spectral features with line widths of a few km s−1 are detected, supporting the hypothesis that they are masing. Compared to other nearby galaxies with the detections in the 36.2 GHz methanol maser transition, the maser detected in Maffei 2 has about an order of magnitude higher isotropic luminosity, and thus represents the first confirmed detection of class I methanol megamasers. The spatial distribution of the 36.2 GHz maser spot clusters may trace the rotational gas flow of the galactic bar, providing direct evidence that the class I methanol maser is related to shocks induced by galactic bar rotation. A tentative detection in the 6.7 GHz class II methanol maser (at a 5σ level) is also reported. This is comparable in luminosity to some of the 6.7 GHz maser sources detected in Galactic star-forming regions. The 6.7 GHz methanol emission appears to be associated with star formation activity in a smaller volume, rather than related to the larger-scale galactic activities.
Estimations and Scaling Laws for Stellar Magnetic Fields
Authors: Wei Xing
Published: February 2022

In rapidly rotating turbulence (i.e., a Rossby number much less than unity), the standard mixing length theory for turbulent convection breaks down. However, the Coriolis force enters the force balance such that the magnetic field eventually depends on rotation. By simplifying the self-sustained magnetohydrodynamics dynamo equations of electrically conducting fluid motion, with the aid of the theory of isotropic nonrotating or anisotropic rotating turbulence driven by thermal convection, we make estimations and derive scaling laws for stellar magnetic fields with slow and fast rotation. Our scaling laws are in good agreement with the observations.
Stellar Loci. V. Photometric Metallicities of 27 Million FGK Stars Based on Gaia Early Data Release 3
Authors: Xu Shuai , Yuan Haibo , Niu Zexi , Yang Lin , Beers Timothy C. , Huang Yang
Published: February 2022

We combine LAMOST DR7 spectroscopic data and Gaia EDR3 photometric data to construct high-quality giant (0.7 < (BP − RP) < 1.4) and dwarf (0.5 < (BP − RP) < 1.5) samples in the high Galactic latitude region, with precise corrections for magnitude-dependent systematic errors in the Gaia photometry and careful reddening corrections using empirically determined color- and reddening-dependent coefficients. We use the two samples to build metallicity-dependent stellar loci of Gaia colors for giants and dwarfs, respectively. For a given (BP − RP) color, a 1 dex change in [Fe/H] results in about a 5 mmag change in (BP − G) color for solar-type stars. These relations are used to determine metallicity estimates from EDR3 colors. Despite the weak sensitivity, the exquisite data quality of these colors enables a typical precision of about δ [Fe/H] = 0.2 dex. Our method is valid for FGK stars with G ≤ 16, [Fe/H] ≥ −2.5, and E(B − V) ≤ 0.5. Stars with fainter G magnitudes, lower metallicities, or larger reddening suffer from higher metallicity uncertainties. With the enormous data volume of Gaia, we have measured metallicity estimates for about 27 million stars with 10 < G ≤ 16 across almost the entire sky, including over 6 million giants and 20 million dwarfs, which can be used for a number of studies. These include investigations of Galactic formation and evolution, the identification of candidate stars for subsequent high-resolution spectroscopic follow-up, the identification of wide binaries, and to obtain metallicity estimates of stars for asteroseismology and exoplanet research.

Fusarium is one of the most important fungal genera of plant pathogens that affect the cultivation of a wide range of crops. Agricultural losses caused by Fusarium oxysporum f. sp. cubense (Foc) directly affect the income, subsistence, and nourishment of thousands of farmers worldwide. For Viet Nam, predictions on the impact of Foc for the future are dramatic, with an estimated loss in the banana production area of 8% within the next five years and up to 71% within the next 25 years. In the current study, we applied a combined morphological-molecular approach to assess the taxonomic identity and phylogenetic position of the different Foc isolates collected in northern Viet Nam. In addition, we aimed to estimate the proportion of the different Fusarium races infecting bananas in northern Viet Nam. The morphology of the isolates was investigated by growing the collected Fusarium isolates on four distinct nutritious media (PDA, SNA, CLA, and OMA). Molecular phylogenetic relationships were inferred by sequencing partial rpb1, rpb2, and tef1a genes and adding the obtained sequences into a phylogenetic framework. Molecular characterization shows that c. 74% of the Fusarium isolates obtained from infected banana pseudostem tissue belong to F. tardichlamydosporum. Compared to F. tardichlamydosporum, F. odoratissimum accounts for c.10% of the Fusarium wilt in northern Viet Nam, demonstrating that Foc TR4 is not yet a dominant strain in the region. Fusarium cugenangense – considered to cause Race 2 infections among bananas – is only found in c. 10% of the tissue material that was obtained from infected Vietnamese bananas. Additionally, one of the isolates cultured from diseased bananas was phylogenetically not positioned within the F. oxysporum species complex (FOSC), but in contrast, fell within the Fusarium fujikuroi species complex (FFSC). As a result, a possible new pathogen for bananas may have been found. Besides being present on several ABB ‘Tay banana’, F. tardichlamydosporum was also derived from infected tissue of a wild Musa lutea, showing the importance of wild bananas as a possible sink for Foc.
Partie III. Le renouveau de l’inflation ?
Authors: Le Bayon Sabine , Péléraux Hervé
Published: February 2022

Après une année 2020 frappée de plein fouet par la pandémie de Covid-19, une baisse de la demande et une très faible inflation, l’année 2021 a vu la reprise accompagnée d’un fort rebond inflationniste. Le prix de l’énergie a flambé et de nombreuses matières premières ont vu leur prix augmenter également du fait de tensions importantes sur l’offre. L’inflation sous-jacente est pour le moment encore modérée dans la zone euro, mais elle inquiète au Royaume-Uni et surtout aux États-Unis où l’importance des plans de relance et les pénuries de main-d’œuvre accentuent les tensions. Le retournement à la baisse des prix de la plupart des matières premières depuis le printemps ou l’automne 2021 devrait contribuer négativement à l’inflation au cours de l’année 2022. Pour évaluer l’ampleur de cette contribution, nous avons estimé la sensibilité du déflateur de la consommation au prix des matières premières importées. Nous avons en particulier mesuré l’impact différencié d’un retour du prix du pétrole à 65 euros et de son maintien à 80 euros sur l’inflation en 2022.
Théories personnelles d’étudiants universitaires sur l’utilité des émotions et sur la nécessité de les réguler en contexte de préparation d’examens
Authors: Fischer Line , Philippot Pierre
Published: February 2022

Cet article propose d’explorer les théories personnelles que possèdent des étudiants universitaires sur les émotions qu’ils vivent en contexte d’apprentissage. Les théories personnelles de 23 étudiants sur l’utilité des émotions et sur la nécessité de les réguler dans le contexte de préparation d’une première session d’examens sont investiguées via une méthodologie mixte (entretiens semi-structurés et questionnaires). Les résultats indiquent que l’utilité de l’émotion pour l’étude dépend avant tout de la manière dont l’étudiant perçoit l’émotion et son impact sur l’apprentissage. Les émotions agréables ont été jugées globalement utiles, même si leur excès est parfois identifié comme une menace à l’étude. Elles sont vues comme nécessaires à réguler pour certains étudiants mais pas pour d’autres. Les émotions désagréables ont été jugées moyennement utiles et nécessaires à réguler selon leur nature et leur intensité. Ces résultats suggèrent que, suite à la préparation d’une première session universitaire, les étudiants semblent conscients de l’impact des émotions sur l’apprentissage et de la nécessité de les réguler pour poursuivre leurs objectifs de formation.

La présente contribution examine, à partir de leurs déclarations rétrospectives, la manière dont 50 enseignants issus de 5 facultés/filières (Sciences appliquées, Psychologie, Sciences, Histoire, Sciences politiques) ont assuré, pour un cours défini, la « continuité de l’activité académique » à la suite du confinement COVID-19 de mars 2020. Les résultats suggèrent, d’une part, que le caractère exceptionnel des circonstances affrontées a pris le dessus sur la variété des réponses pédagogiques apportées et, d’autre part, que, dans le tumulte apparent lié à la pandémie, l’université est malgré tout parvenue à amortir les effets de cette perturbation de grande envergure. L’article confronte ces observations à l’avis des étudiants sur les mêmes 50 cours. Il en ressort là aussi une vision des bouleversements moins négative que ce que l’ampleur du « basculement vers l’enseignement virtuel » aurait pu laisser présager.
Teacher readiness in STEM education: Voices of Indonesian Physics teachers
Authors: Sulaeman Nurul , Efwinda Shelly , Putra Pramudya Dwi Aristya
Published: February 2022

STEM (science, technology, engineering, mathematics) education is widespread around the globe, with various theoretical frameworks and challenges from practical perspectives. In classroom practice, teacher readiness to conduct STEM learning is essential for its successful implementation. This study explores physics teachers’ readiness for STEM education using the Alignment, Capabilities, Engagement, or ACE, framework. Data collection is based on 101 teachers’ responses to six open-ended questions. Interestingly, all the teachers showed strong alignment with STEM education and how to implement it. Most of them have known STEM education as integrating technology, engineering, and mathematics to science (physics), but only about half of them have experience conducting STEM lessons. They have basic capabilities of identifying the possibilities of implementation in various physics curricula, such as motion, electricity, and fluids. However, in the online learning made necessary by the COVID-19 pandemic, the possibility of implementation is weakened. The teachers showed their engagement to explore more detail in designing and implementing STEM in their classrooms. Also reflected in the study was a significant challenge in terms of pedagogical and time management. Therefore, professional development in STEM education is essential to support teachers’ alignment, capabilities, and engagement to develop their readiness. As specific examples, STEM learning materials in motion, electricity, and fluids could help teachers understand the design and implementation of STEM education.
Exploratory study on didactic aspects used in scientific-technical (STEM) dissemination conferences for students of secondary education
Authors: Fuentes del Burgo Joaquin , Sánchez Tomás Juan Manuel , Ballesteros Garrido José Antonio , González Geraldo José Luis
Published: February 2022

The connection between education and a country's economic and social development is unquestionable, and science and technology-related careers are of particular importance. Given the lack of vocations in these degrees, a number of mechanisms have been used to attract students, including science and technology conferences in secondary schools. Focusing on this type of lectures, this article aims to analyse the didactic aspects used by university lecturers who deliver this type of lectures. To this end, 16 teachers were interviewed using a structured interview. From the qualitative analysis of the interviews, we reached a series of results and conclusions, among which we would like to highlight the following: teachers see these lectures as a form of scientific dissemination which also helps to promote the degree courses they teach and serves as a support for attracting students; when choosing the content of the lecture, they mainly take into account the secondary school curriculum, including striking aspects and the results of their own research; the mediums used are mainly visual and supported by Do It Yourself techniques; the content is normally presented through presentations or practical laboratory exercises; finally, the documentation provided to students depends on the teacher giving the lecture, and there is no consensus on this point.

Published: February 2022

This study aims to assess the effectiveness of applying a socio-critical problem-oriented approach in environmental issues to develop students' critical thinking skills in chemistry learning. The qualitative methodology is conducted in which participants critically analyze articles relating to the effect of acids and bases in the environment. Participants are 36 grade 11 chemistry students from a high school in Jakarta, Indonesia. Data are collected by interviews, reflective student journals, teacher notes, observation sheets, worksheets, and critical thinking skills tests based on the five SCIT 1020 critical thinking indicators: problem identification, conceptual understanding, finding relationships between concepts, developing assumptions, and drawing conclusions. The results show an improvement in students’ critical thinking skills, motivation, and involvement in the learning process, providing support for using a socio-critical and problem-oriented approach to science learning. The socio-critical and problem-oriented can be used as an alternative approach to chemistry learning or other subjects that is applicable and contextual in daily life and the environment and can be used to increase student activity in the classroom and critical thinking skills on learning process.

In this paper, we prove Hermite-Hadamard inequality for convex functions in the framework of $ \mathfrak{h} $-calculus. We also use the notions of $ \mathfrak{h} $-derivative and $ \mathfrak{h} $-integral to prove Ostrowski's and trapezoidal type inequalities for bounded functions. It is also shown that the newly established inequalities are the generalization of the comparable inequalities in the literature. Finally, using some examples, we demonstrate the validity of newly formed inequalities and show how they can be used to special means of real numbers.
Analysis of Engineering Technology Students’ Digital Footprints in Synchronous and Asynchronous Blended Courses
Authors: Appiah-Kubi Philip , Zouhri Khalid , Basile Emily , McCabe Melissa
Published: February 2022

The advent of Covid-19 provided an enormous academic and logistical challenge to almost all academic institutions in the United States and around the world. As a precautionary measure surrounding the novel coronavirus and in line with recommendations from the Center for Disease Control and Prevention (CDC) at that time (spring 2020), most higher education institutions in the United States shut down campuses and completed the second half of the spring 2020 semester virtually. During the fall 2020 semester, when relatively more was known about the virus, some institutions started with face-to-face classes but had to switch to virtual learning after noticing a spread of the coronavirus on their campuses. Others adopted a blended approach that supplements face-to-face meetings with virtual learning synchronously or asynchronously. Whichever approach adopted in place of the traditional face-to-face meetings did not necessarily solve the challenge faced by Engineering Technology programs, which typically infuse hands-on learning in most of the courses in their curriculum. Due to the applied nature of engineering technology, it is important to ensure that students stay engaged with creative ways to learn by doing. And to ensure that the students do not miss critical course content in virtual and blended engineering technology courses, it is vital that the students maintain high interactions with online resources such as class video recordings. This paper reviews students’ patterns of interactions with course videos to assess its impact on the academic success of engineering technology students in some upper-level blended courses delivered during the spring and fall 2020 semesters.

Measuring the Maturity of the Business Intelligence and Analytics Initiative of a Large Norwegian University
Authors: Su Xiaomeng , Cardoso Elsa
Published: February 2022

Maturity models of Business Intelligence and Analytics (BIA) have been previously used to assess BIA development progress in organizations in many sectors, such as healthcare and business. However, there is a lack of studies reporting up-to-date knowledge on applying maturity assessment in Higher Education Institutions (HEI). It remains unclear precisely to what extent and how HEI employ maturity assessment and the benefits of such exercises. This paper addresses this gap by reporting a case study at a large Norwegian university. A domain-specific maturity model is used as a lens to observe and reflect on the BIA implementation at the Norwegian University of Science and Technology. This paper reports the assessment results and discuss the implications of the maturity assessment. The findings and discussions in the case can cater to a broader audience of BIA practitioners and researchers, contributing to understanding the value and adoption dynamics of BIA in Higher Education.
Study on the Effects of Hydrostatic Pressure on the Structural State of Pure-Iron during Hardening Treatment with a Multiradius Roller
Authors: Blumenstein V.Yu. , Mitrofanova K.S.
Published: February 2022

The study looks at features the formation of the structure of the surface layer of pure-iron after hardening treatment with surface plastic deformation (SPD) by a multiradius roller (MP-roller). Earlier authors with the help of the method of finite-element modelling (FEM) of the MP-roller SPD process proved the possibility of creating high hydrostatic pressure in the deformation center of the part being processed. The methods of optical (OM) and atomic-force microscopy (AFM) and X-ray structural analysis have determined that the MR-roller SPD results in the formation of an intensively deformed surface layer of the component with characteristic ferrite grains, stretched in the direction of the current of the metal and an average size of 20-30 μm. Analysis of the results of the X-ray structural analysis showed that the processing of the SPD by the MP-roller results in a significant increase in the microdistortion of the crystal lattice, which is characteristic of the nanodimensional structure. The data obtained are well consistent with the results of the finite element modelling previously obtained.

Welded flexible compensating elements made of austenitic stainless steels, such as metal hoses and bellows expansion joints, operate in a complex stress state; therefore, almost all corrosion damage of these products occurs in a stressed state. In addition, in welded joints, defects are possible associated with elastic-plastic deformations and stresses arising in the manufacturing process. Paper considers the defects of welded joints of multilayer bellows expansion joints made of stainless steels AISI 304 and AISI 316 types. The influence of the parameters of the argon tungsten electrode welding mode, with or without filler wire, on the mechanical characteristics of welded joints was studied. Mechanical tests of samples of welded joints were carried out on a tensile testing machine. The optimal range of variation of the parameters of the welding mode has been established, in which the plastic characteristics of the welded joints have maximum values. A metallographic study of the microstructure of welded joints of metal hoses and bellows expansion joints was carried out. The influence of the content of nonmetallic inclusions in the material of products on the conditions of melting and crystallization of the weld pool, contributing to the appearance of pores and hot cracks in the metal of the weld and the heat affected zone, has been established. To reduce the influence of the content of non-metallic inclusions in the weld metal and the heat-affected zone on the conditions of melting and crystallization of the weld pool, it is recommended to carry out preliminary heat treatment of the austenitic steel strip.

Although coronavirus disease 2019 (COVID-19) remains rampant in many countries, it has recently waned in Sichuan, China. This study examined spatiotemporal variations of the epidemiological characteristics of COVID-19 across its course. Three approaches, i.e. calendar-based, measure-driven and data-driven ones, were applied to all individual cases reported as of 30th November 2020, dividing the COVID-19 pandemic into five periods. A total of 808 people with confirmed diagnosis and 279 asymptomatic cases were reported, the majority of whom were aged 30-49 and <30 years, respectively. The highest risk was seen in Chengdu (capital city), with 411 confirmed and 195 asymptomatic cases. The main sources of infection changed from importation from Hubei Province to importation from other provinces, then local transmission and ultimately importation from foreign countries. The periods highlighted by the three methods presented different epidemic patterns and trends. The calendar-based periods were even with most cases aggregated in the first period, which did not reflect various transmission patterns of COVID-19 due to various sources of infection; the measure-driven and data-driven periods were not consistent with each other, revealing that the effects of implementing prevention measures were reflected on the epidemic trend with a time lag. For example, the decreasing trends of new cases occurred 7, 3 and 4 days later than the firstlevel emergency response, the district-level prevention measures and the second-level emergency response, respectively. This study has advanced our understanding of epidemic course and foreshown all stages of COVID-19 epidemic. Many countries can learn from our findings about what will occur next in their timelines and how to be better prepared.
Adolescent Patient, Parent, and Clinician Perceptions of Rehabilitation After Anterior Cruciate Ligament Reconstruction: A Qualitative Study
Authors: Kuenze Christopher M. , Farner Nathan , Lewis Jordan , Lisee Caroline Michele , Schorfhaar Andrew , Erickson Karl
Published: February 2022

Context

Rehabilitation after anterior cruciate ligament reconstruction (ACLR) is challenging for adolescent patients concurrently experiencing growth and development, changes in attitudes and social interactions, and a gradual shift toward independence.

Objective

To examine the perceptions of information sharing and interpersonal communication among adolescent patients going through ACLR, their parents, and physical therapists (PTs) treating adolescent patients with ACLR.

Design

Cross-sectional study.

Setting

University-affiliated sports medicine clinic.

Patients or Other Participants

Nine adolescent patients who had recently completed physical rehabilitation after ACLR, one of their parents, and PTs who treated adolescent patients with ACLR were recruited and enrolled.

Main Outcome Measure(s)

Participants completed semistructured interviews. The interview scripts for patients, parents, and PTs intentionally addressed the same topics, with only minor modifications in wording as appropriate for each role. All interviews were recorded, transcribed verbatim, and analyzed using a hybrid of deductive and inductive coding by trained members of the study team.

Results

Patients, parents, and PTs perceived that interpersonal dynamics (eg, communication, external motivation) and stakeholder knowledge (eg, understanding of the psychological consequences of injury) influenced intrapersonal experiences (eg, emotional response, intrinsic motivation) during rehabilitation after ACLR. Additionally, patients and parents indicated that a lack of information about the rehabilitation process hindered their ability to obtain additional information from the PT and surgeon.

Conclusions

Participants from all stakeholder groups reported that orthopaedic surgeons and other members of the health care team may consider being more consistent when setting expectations, physical restrictions, and recovery timelines.
Lessons Learned and Potential Long-Term Effects on Athletic Trainers and Clinical Practice After a Global Pandemic
Authors: Madden Meredith , Kneavel Meredith E. , Bowman Thomas G.
Published: February 2022

Context

Perceived stress and burnout are significant concerns among athletic trainers (ATs) due to growing professional demands. The global COVID-19 pandemic brought additional stressors, especially for health care providers, including the need to learn and integrate new skill sets in order to continue providing safe and effective patient care.

Objective

To explore the influence of COVID-19 stressors on ATs engaged in patient care.

Design

Cross-sectional study.

Setting

Internet survey.

Patients or Other Participants

A total of 429 ATs (age = 33 ± 9 years; experience = 11 ± 9 years; 74 men, 355 women) currently providing patient care.

Main Outcome Measure(s)

We recruited participants from social media sites to complete a questionnaire with the Coronavirus Anxiety Scale (CAS), Maslach Burnout Inventory-Human Services Survey for Medical Personnel (MBI-HSS MP), and qualitative questions related to the effects of COVID-19. We calculated correlations between CAS and MBI-HSS MP composite scores (emotional exhaustion, personal accomplishment, and depersonalization) and used regression analysis to explore if CAS scores could be predicted by vaccination status (vaccinated or unvaccinated), sex, and MBI-HSS MP composite scores. We analyzed the qualitative data using a phenomenological, inductive approach with multianalyst triangulation and peer review as trustworthiness strategies.

Results

Significant correlations existed between CAS and MBI-HSS MP composite scores (P < .001). Emotional exhaustion (P < .001) and depersonalization (P = .008) explained 28% of the variance in CAS scores (F2,405 = 81.29, P < .001). Three major areas of focus emerged: effects on wellness, emphasis on the value of athletic training, and the lessons learned and future innovation to inform potential long-term changes in the athletic training profession.

Conclusions

Key factors of emotional exhaustion and depersonalization during the pandemic may have exacerbated the potential for burnout among ATs. The pandemic affected ATs' wellness, changed perceptions of ATs, and altered operating procedures. Healthy coping strategies and organizational support are suggested for those who are struggling.

Published: February 2022

Purpose Tropomyosin receptor kinase (TRK) inhibitors are approved for the treatment of neurotrophic receptor tyrosine kinase (NTRK) fusion-positive tumors. The detection of NTRK fusion using a validated method is required before therapeutic application. An interlaboratory comparison study of next-generation sequencing (NGS)–based NTRK gene fusion detection with validated clinical samples was conducted at six major hospitals in South Korea.Materials and Methods A total of 18 samples, including a positive standard reference and eight positive and nine negative clinical samples, were validated using the VENTANA pan-TRK (EPR17341) and TruSight Oncology 500 assays. These samples were then tested using four different NGS panels currently being used at the six participating institutions.Results NTRK fusions were not detected in any of the nine negative clinical samples, demonstrating 100% specificity in all six participating institutions. All assays showed 100% analytical sensitivity to identify the NTRK fusion status in formalin-fixed paraffin-embedded (FFPE) samples, although with variable clinical sensitivity. False-negative results were due to low tumor purity, poor RNA quality, and DNA-based sequencing panel. The RNA-based targeted NGS assay showed an overall high success rate of identifying NTRK fusion status in FFPE samples.Conclusion This study is the first to test the proficiency of NGS-based NTRK detection in South Korea with the largest participating institutions. RNA-based NGS assays to detect NTRK fusions can accurately characterize fusion transcripts if sufficient RNA of adequate quality is available. The comparative performance data will support the implementation of targeted NGS-based sequencing assays for NTRK fusion detection in routine diagnostics.
