Authors: Deghdegh Khaled , Boukadoum Nassim , Terra Besma , Amoura Kamel , Benali Rachid
Published: May 2022

Introduction:

An association between chronic Obstructive Pulmonary Disease (COPD) and bronchiectasis has been observed. However, the incidence of this association is variable. The current use of high-resolution Chest Thoracic (CT) scans in patients with COPD has contributed to its demonstration. It is comorbidity or even an overlap syndrome. The aim of this study is to determine the characteristics of bronchiectasis in patients with COPD at the Annaba University Hospital in Algeria.

Subjects and Methods:

We prospectively included patients hospitalized at the Annaba University Hospital in Algeria between 1st January, 2013 to 31st December, 2015. All patients were hospitalized for an exacerbation of COPD. One hundred and twelve patients (108 men and 04 women) were enrolled in this study. These patients were classified into two groups: G1 (COPD without bronchiectasis) and G2 (COPD with bronchiectasis). The parameters considered for both the groups were the length of hospitalization, comorbidities as per the Charlson index, number of exacerbations in the previous year, quality of life assessed by the Saint Georges questionnaire, a spirométrie, and C. reactive protein (CRP). The diagnosis of exacerbation, bronchiectasis, and COPD was made. The data collected were statistically analyzed using SPSS/version 16. Parametric data were expressed as mean ± SD, and non-parametric data were expressed as the number and percentage of the total. In all tests, a p-value <0.05 was considered significant. Multivariate logistic regression analysis was performed for statistically significant variables.

Results and Discussion:

One hundred and twelve patients (108 men and 04 women) were included in the study. The demographic characteristics of the patients were: age (69.49 years ± 8.15), smoking (53.21 ± 48 p/y), and FEV1(42.55 ± 18.90 l/s). Of the 112 cases included, 21 had COPD associated with bronchiectasis (18.75%). This bronchiectasis was of cylindrical type in the majority of patients, i.e., 17 (80.95%), saccular in 03 cases (14.28%), and mixed in only one case (04.77%). Lesions were bilateral in 16 patients (76.19%) and unilateral in 05 patients (23.81%). FEV1 in the COPD group associated with bronchiectasis was more severe (48.7 ± 6 l/s vs. 40.2 ± 3 l/s) (OR=4.3187; 95% C.I =2.6301 - 6.8740; p <0.017). Furthermore, we noted that the length of hospitalization, the exacerbations during the past year, the CRP rate, the total score of the Saint Georges questionnaire, and the sputum purulence were statistically significant variables with an Odds Ratio significant in the COPD bronchiectasis association

Conclusion:

The diagnosis of bronchiectasis should be more efficient in patients with COPD with a severe respiratory deficit, purulent sputum, accelerated CRP, and deterioration in the quality of life.

Hippophae salicifolia, belonging to family Elaegnaceae, is a thorny shrub, and shows actinorhizal habit. The species prefers a habitat of temperate regions in Europe and Asia. In India, it is distributed in the Himalayan region of Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and the North-Eastern parts. The oil, fruits, leaves, and bark of Hippophae species have a pronounced use in ethnomedicines, nutritional food, cosmetics, nitrogen-fixing in soil, water conservation and as fuel source. The aim of this review is to provide updated, comprehensive, and classified information on the traditional uses, phytochemistry, pharmacological and toxicological research carried out on H. salicifolia. This will help researchers to explore its therapeutic potential and examine future research possibilities. The chemical composition of this shrub comprises minerals, vitamins, flavonoids, flavonoid glycosides, polyunsaturated fatty acids, sugars, carotenoids, and nucleobases. Pharmacological studies demonstrated that the extracts prepared from leaves, barks, and berries along with fixed oil of this species are useful as anti-oxidant, anti-inflammatory, anti-cancer, anti-diabetic, anti-depressant, anti-microbial, adaptogenic, and wound healing. The results of toxicity study of H. salicifolia extracts did not show any significant acute toxicity in experimental animals. Abundance of phenolic compounds, minerals, and fatty acids within the different parts of this plant prompted researchers to isolate and characterize the phytoconstituents which are responsible for its therapeutic uses.
Knowledge Representation and The Semantic Web: An Historical
Overview of Influences on Emerging Tools
Authors: DeBellis Michael , Neches Robert
Published: May 2022

suite of standards known as the Semantic Web is transforming the Internet into a
semantic graph rather than a graph of hypertext links. This paper will describe how various ideas
and initiatives in artificial intelligence knowledge representation influenced its design. We begin
with the seminal work by Alan Turing and Alonzo Church that led to the definition of Turing
Machines, enabled digital computing, and provided the mathematical theory of computation,
which has been one of the determining factors for Artificial Intelligence knowledge representation.
We then provide a brief history of artificial intelligence knowledge representation,
starting with groundbreaking researchers, such as Newell and Simon, then to the first "AI boom"
driven primarily by rule-based expert systems, followed by major initiatives such as Cyc and the
DARPA Knowledge Sharing Initiative. We will discuss how innovations from these initiatives
affected standards that, in turn, led to the suite of standards known as the Semantic Web. We
conclude with a brief overview of the most important issues currently facing those who wish to
see widespread adoption of Semantic Web technology in the industry.

Lead is a kind of non-essential heavy metals included in the metal causing environmental pollution with persistent properties that might harm the consumers. This study aimed to determine the best method for reducing the lead level on the freshwater snail Filopaludina javanica using three various water treatment models. Soaking water treatment (6h, 12h, 18h, 24h), flowing water treatment (6h, 12h, 18h, 24h), and refreshing water treatment (6h, 12h, 24h). The lead level assay in both samples used Atomic absorption spectroscopy (AAS), and the physical and chemical parameters were measured, such as temperature, pH, and Dissolved Oxygen (DO). The lowest value of lead content on freshwater’s soft body snail and water sample respectively were soaking water treatment at 6h (0.64 ± 0.02 mg L-1) and 24h (0.0045 ± 0.0015 mg L-1); flowing water treatment at 24h (0.04 ± 0.007 mg L-1) and 18h (0.0036 ± 0.0009 mg L-1) and; refreshing water treatment at 24h (0.150 ± 0.011) and 12h (0.007 ± 0.001), with control 0.072 ± 0.00 mg L-1 and 0.067 ± 0.00 mg L-1. Therefore, the most effective model to reduce the lead content was flowing water treatment within 24h in the freshwater soft body snail and 18h in the water sample.

Authors: Herawati Reni , Tjahjono Heru Kurnianto , Qamari Ika Nurul , Wahyuningsih Sri Handari
Published: May 2022

This study aimed to highlight the view of educators on the teachers’ willingness to change in adapting to online learning due to the Coronavirus disease 19 (COVID -19) pandemic. The sudden shifting required readiness to facilitate both synchronous and asynchronous learning interactions. The results of previous studies on the dissatisfaction with the online learning quality during the pandemic triggered this study. Teachers preferred to use task-based learning and resisted incorporating technology in the learning process. The limited literature provided a study gap investigated in the present study. Therefore, the real-time virtual focus group discussions were carried out to obtain viewpoints about teachers’ willingness to change in which 31 participants, including teachers, principals, and supervisors, shared their viewpoints. Moreover, dynamic discussions were conducted through brainstorming using Mentimeter, collecting viewpoints via zoom poll, and discussion engagements in the primary and breakout rooms. Content analysis revealed three categories: willingness to learn, try, and be open. The result provided novelty essential as a new perspective and proposed possible solutions to address the problems shifting from regular to online learning in Indonesia. Finally, this study recommends future investigation of teachers’ willingness to change as a new concept of professional development in establishing quality learning.

Published: May 2022

El cultivo de cítricos en Colombia, desde el 2016, está en riesgo por la enfermedad huanglongbing – HLB. El municipio de Ponedera (Atlántico) es uno de los más afectados por la enfermedad, sin embargo, existe escasa información sobre el impacto en el sistema productivo de los cítricos. Con el propósito de categorizar a los productores, identificar sus condiciones y dimensionar el impacto del HLB, a 134 agricultores se les aplicó una encuesta semiestructurada con 79 preguntas sobre aspectos socioeconómicos, ambientales y agronómicos con énfasis en el conocimiento de la enfermedad. Mediante análisis descriptivo y correspondencia múltiple se seleccionaron las variables con mayor aporte a la categorización de los productores, con la identificación de cinco grupos de acuerdo con la asistencia a capacitaciones, especies cítricas, tipo y origen del material de propagación y categoría de edad del limón común (Citrus aurantifolia Swingle), y categoría de edad y marco de siembra de la lima ácida Tahití (Citrus × latifolia Tanaka ex Q. Jiménez). Este estudio determinó que entre 2016 y 2020, más del 85% de los agricultores perdió, al menos, el 50% de los árboles debido a limitantes como: carencia de riego (67,6%), de fertilización (75,4%), de control del psílido asiático de los cítricos (76,9%) o de HLB (87,3%). Asimismo, evidenció el efecto devastador de la enfermedad HLB en el cultivo. La caracterización de los productores estableció la capacitación como una variable diferenciadora, resultado que servirá para el desarrollo de ofertas tecnológicas, extensión agrícola y formación de clústeres productivos.

Published: May 2022

Background

Oral nicotine pouches are a new form of tobacco-free nicotine products launched in recent years with a variety of flavors.

Objective

This study aims to examine the public perceptions and discussions of oral nicotine pouches on Reddit, a popular social media platform for sharing user experiences.

Methods

Between February 15, 2019, and February 12, 2021, a total of 2410 Reddit posts related to oral nicotine pouches were obtained over a 2-year period. After the removal of unrelated or commercial posts, 653 Reddit posts related to oral nicotine pouches remained. Topics and sentiments related to oral nicotine pouches on Reddit were hand coded.

Results

The number of Reddit posts related to oral nicotine pouches increased during the study period. Content analysis showed that the most popular topic was “sharing product information and user experience” (366/653, 56%), in which sharing oral nicotine pouch products and user experiences were dominant. The next popular topic was “asking product-related questions” (product properties and product recommendations; 115/653, 17.6%), followed by “quitting nicotine products” such as vaping or smoking through use of oral nicotine pouches or quitting the oral nicotine pouches themselves (83/653, 12.7%) and “discussing oral nicotine pouch–related health” symptoms or concerns related to oral nicotine pouches (74/653, 11.3%). The least popular topic was “legality and permissions” related to oral nicotine pouches (15/653, 2.3%). In addition, a greater number of Reddit posts described positive attitudes compared to negative attitudes toward oral nicotine pouches (354/653, 54.2% vs 101/653, 15.5%; P<.001).

Conclusions

Reddit posts overall had a positive attitude toward oral nicotine pouches and users were actively sharing product and user experiences. Our study provides the first insight on up-to-date oral nicotine pouch discussions on social media.

Authors: Folkvord Frans , Peschke Lutz , Ağca Yasemin Gümüş , van Houten Karlijn , Stazi Giacomo , Lupiáñez-Villanueva Francisco
Published: May 2022

Background

Despite the worldwide growth in using COVID-19 contact tracing apps (CTAs) and the potential benefits for citizens, governments, health care professionals, businesses, and other organizations, only a few studies have examined the factors affecting the levels of willingness to download a CTA.

Objective

This study aimed to investigate individuals’ preferences in the willingness to download a health app.

Methods

We conducted an experimental study in 2 countries, the Netherlands (N=62) and Turkey (N=83), using 4 different vignettes (ie, data protection, manufacturer, reward, and gaming models) with different attributes. Participants were randomly assigned to 1 of the conditions within the vignettes.

Results

The results showed that data protection and gaming elements are factors that influence the willingness to download a COVID-19 CTA. More specifically, we see that data protection is an important factor explaining the willingness to download the app in Turkey, whereas including gaming elements significantly affects the willingness to download the app in the Netherlands.

Conclusions

COVID-19 CTAs are highly promising to reduce the spread of the virus and make it easier to open up society faster, especially because they can be used quickly and share information rapidly. COVID-19 CTA developers must ensure that their apps satisfactorily and sufficiently address ethical considerations, even in times of crisis. Furthermore, integrating gaming elements in the CTA could enhance the willingness to download the CTA.
Understanding the Effect of Face Masks on the Use of Echolocation for Persons with Visual Impairments During COVID-19: An International Cross-sectional Online Survey (Preprint)
Authors: Kreidy Chantal , Martiniello Natalina , Nemargut Joseph-Paul , Wittich Walter
Published: May 2022

BACKGROUND

Although a critical safety measure, preliminary studies have suggested that the use of a face mask may pose a problem for some users with disabilities. To date, little is known about how the wearing of a traditional face mask may pose a barrier to individuals with visual impairments who draw on auditory cues and echolocation techniques during independent travel.

OBJECTIVE

The goal of this study was to document the difficulties, if any, encountered during orientation and mobility due to the use of a face mask during the COVID-19 pandemic and the strategies used to address these barriers.

METHODS

135 Individuals 18 years and older who self-identified as being blind, deafblind or having low vision and who could communicate in either English or French completed an anonymous online survey between March 29 and August 23, 2021.

RESULTS

In total, n=135 respondents (39% men, 61% women) between the ages of 18-79 (M=48.22, SD=14.48) participated. Overall, n=78 (58%) self-identified as blind and n=57 (42%) as having low vision. Thirteen (13%) identified as having a combined vision and hearing loss, and n=3 (2%) as deafblind. The most common face coverings used were cloth (89%, n=119) and surgical masks (55%, n=74). Among the barriers raised, participants highlight that face masks made it more difficult to locate people (64%), communicate with others (75%), and locate landmarks (61%). While the percentage of those who used a white cane before the pandemic did not substantially change, 6 of the 41 participants who were guide dog users prior to the pandemic reported no longer working with a guide dog at the time of the survey. Moreover, although guide dog users reported the highest level of confidence with independent travel before the pandemic, they indicated the lowest level of confidence a year after the pandemic began.

CONCLUSIONS

These results suggest that participants were less able to draw on non-visual cues during independent travel and social interactions due to the use of a facemask, contributing to a reduction in perceived self-confidence and independence. Findings inform the development of evidence-based recommendations to address identified barriers.

Authors: Gross Georg Matthias , Lull Christian , von Ahnen Jan , Olsavszky Victor , Knitza Johannes , Schmieder Astrid , Leipe Jan
Published: May 2022

BACKGROUND

Psoriatic arthritis (PsA) is a chronic musculoskeletal disease. Functional limitations result in significant patient burden. The usage of smartphone apps to complement medical treatments could increase patients’ adherence to treatment resulting in a better clinical outcome and consequently increased quality of life.

OBJECTIVE

We assessed and compared currently available smartphone apps for PsA patients using a standardized rating scale.

METHODS

We conducted a systematic screening of apps for PsA patients in German App Stores and selected apps meeting inclusion criteria: availability in both app stores,German or English language, relevant for patients with psoriatic arthritis, not developed for congress usage or clinical studies, no fee-based apps. Three reviewers evaluated apps using the Mobile Application Rating Scale. Analysis included technical features and mean scores as well as interrater agreement and linear regression. The best-rated app was then rated by PsA patients.

RESULTS

Among 232 screened apps, 8 met all inclusion criteria. The app “Rheuma-Auszeit” scored highest with an HCP MARS rating of 4.4 and a lower patient uMARS rating of 3.7. Subjective quality was lower for all apps. App store star ratings and MARS ratings were not significantly correlated (P=0.34). No app was CE certified and no underlying clinical studies could be identified.

CONCLUSIONS

App quality was heterogenous and generally low. Star ratings – as the only accessible tool for patients – does not suffice to identify high-quality apps. We suggest patients be involved in development of apps. Since patients and physicians have different perceptions of app quality, we recommend a joint development and evaluation process.

Utilizing wearable devices to improve patient care: Cross-sectional survey (Preprint)
Authors: Vaughan Ashley , Warner Hayden , Gannon Margaret , Pearlman Amy
Published: May 2022

BACKGROUND

Wearable devices are commonplace in today's society. The term "wearable device" includes a vast array of products and have the ability to collect a tremendous amount of patient data. Despite this, clinicians often depend on less reliable methods of data collection, influenced by patient recall.

OBJECTIVE

This project aimed to assess specific outcomes (measurables) physicians across multiple specialties would be most interested in tracking to improve patient care.

METHODS

A REDCap survey was distributed to U.S. based physicians and advanced practice providers (APPs) in current clinical practice to investigate current and prospective use of wearable devices in the clinical setting. Participation was voluntary.

RESULTS

110 physicians and APPs responded to the survey. Family medicine (13.6%), pediatrics (12.7%), internal medicine (10.9%), and urology (10.9%) were the most represented specialties. The majority of respondents did not currently use data from wearable devices in practice (73%, n=81), but 50 respondents reported using data collected outside of the clinic setting (e.g., devices, symptom diaries, surveys). Of those who currently used wearable devices for patient care (n=30), 73.3% used Apple watches, followed by Fitbit devices (46.7%), Holter monitor (30%), heart rate monitor (16.7%), and other smart watches (6.7%). The most useful data reported were step count/miles walked (67.0%), sleep hours/quality (60.6%), blood pressure (56.9%), resting heart rate (53.2%), heart rate variability (47.7%), and weight (44%). Sixty-one of 90 respondents thought that about half, most all, or all of their patients would be willing to use a wearable device to collect data outside of the clinic setting.

CONCLUSIONS

Though fewer than 30% of survey respondents currently used wearable devices for patient care, nearly half reported using data collected outside of the clinic setting and a majority thought that 50% or more of their patients would be willing to use wearable devices. Our results emphasize the importance of continued development and implementation of wearable devices in patient care.

Authors: Purbawa Yudha
Published: May 2022

Background Problems: Land acquisition is a major issue in development policy, and compensation is often described as being inadequate; meanwhile, adequate compensation is the key element of fairness. Main Objectives: The objective of this study is to examine the impact on household welfare of financial compensation for farmland acquisition for new airport development. Novelty: This study utilizes land acquisition for the new Yogyakarta International Airport (YIA) because this area provides a reasonable case for evaluation. Research Methods: A quasi-experimental design is used to draw a causal relationship. A questionnaire survey has been conducted with 452 households, consisting of 207 households in the treatment group and 245 households in the control group. Finding/Results: On average, the financial compensation for the farmland acquired for the new airport development increased a household’s total annual income by as much as 32.06%, especially the income that was generated from self-owned business and farmland activity, and it also increased their total annual expenditures by as much as 26.55%, especially those related to food, energy (LPG and fuel), vehicles, internet and phone, religion, social relationships, and insurance. Conclusion: This study highlights that financial compensation for farmland acquisition for tertiary industry, specifically a new airport development, has a positive impact on both the total annual income and the total annual expenditures.
A REVIEW: TOCILIZUMAB, A RAY OF HOPE IN COVID-19 PNEUMONIA
Authors: BM DIVYA
Published: May 2022

With the increased number of cases of coronavirus disease 2019 (COVID-19) all over the world which was discovered in December 2019 in Wuhan city of China, there are more positive rates and deaths encountered during the second wave due to this dreadful infection mainly focusing on youngsters diagnosed with COVID-pneumonia. Amidst this devastating situation, there is ray of hope by the emerging clinical trials on Tocilizumab, a potent interleukin-6 (Il-6) inhibitor which likely reduces the mortality of those patients having severe COVID-19 pneumonia as a result of Cytokine Release Syndrome. This syndrome is triggered by burst of inflammatory markers secondary to COVID-19 which is characterized by decrease in T-cells and Natural Killer cells, an increase in IL-6, fever, organ and tissue dysfunction, and an abnormal coagulation function eventually leading to death.
Chemical Composition and Bioactivity of Essential Oils of Croton blanchetianus Bailland and Sida cordifolia L. on Callosobruchus maculatus (Fabr., 1775)
Authors: Torres Michele Sousa Travassos , Gervásio Rita de Cássia Rodrigues Gonçalves , Filho José Alves de Siqueira , Torres Yury Jansen Soares Siqueira
Published: May 2022

This study aimed to evaluate the yield and chemical composition of essential oils from Croton blanchetianus and Sida cordifolia, in addition to investigating the insecticidal potential of these oils on adults of the bean weevil, Callosobruchus maculatus. To obtain the oils, the hydrodistillation method was adopted, using a Clevenger apparatus. The identification and quantification of chemical constituents was performed by means of gas chromatography coupled to mass spectrometry (GC-MS). For each oil, fumigation bioassays were performed on adults of C. Macullatus in six concentrations, 0; 0,30; 0,48; 0,60 e 0,70 (µL/750 mL) for C. Blanchetianus. As for the essential oil of S. cordifolia, the concentrations applied were 0, 3, 6, 9, 12 and 15 (µg/750 mL). The bioassays were carried out under constant conditions of temperature (25 ± 2ºC) and relative humidity (60% ± 10%). In the fumigation tests, different concentrations of the oils were applied to strips of filter paper (2x3 cm) attached to the bottom of the lid of a glass container (750mL), which contained 10 grams of cowpea and 15 unsexed adult insects. Insect mortality was evaluated 48 hours after the treatments were applied. Data were submitted to analysis of variance and regression analysis. When possible, lethal doses were calculated for 50 and 95% of the test population (LD50 and LD95). The yield of essential oil from C. blanchtianus was 0.50%, higher than that obtained for S.cordifolia, which was 0.03%. For the species C. blanchetianus, 20 components were identified, with the monoterpene eucalyptol being the major compound (32.89%). For S.cordifolia, 12 components were identified, with sesquiterpene spathulenol being the major compound (31.76%). In fumigation bioassays, considerable insecticidal activity of C. blanchetianus essential oil was observed on C. maculatus adults, with relatively low lethal doses. As for the essential oil of S.cordifolia, the doses used in the study caused a maximum of 5.3% mortality, and it was not possible to determine the LD50 and 90 for the essential oil of this species.

Authors: Rego Oseias Costa , Zingano André Cesar , Junior Erwin Tochtrop , Balduino Angelo Ricardo , Rodrigues Rafael Teixeira
Published: May 2022

Chalcopyrite is an important ore to obtain copper where in Brazil we have several mines located in all regions. The process of ore separation known as flotation is an efficient process that allows the use of bubbles and a foaming material that with the help of collectors are able to conduct the chalcopyrite as well as other ores for separation through appropriate equipment. Currently in this process are used PH modifiers and collectors that allow the separation of this ore with the use of the pneumatic flotation method. The Chitosan is a biotechnological material produced from the exoskeleton of some arthropod animals that can be used as collector in the flotation process. In this work the performance of the Chitosan was analyzed in relation to a very common collector, the Xanthate, and with this it was verified how in media with different concentrations and levels of PH we can verify the efficiency of the Chitosan in the flotation of the Chalcopyrite. The material used in the microflotation tests was the tailings proceeding from copper mining in São Félix do Xingu-PA, lent by the laboratory of Mining Engineering of CEULP/ULBRA, the tests were made in bench with the use of the modified Hallimond tube. The results showed that there was a considerable recovery where in the solution the most indicated pH is pH 9 for maximum recovery.
Cultural Humility in Music Teacher Education: Toward Transformative Dialogues on Power, Privilege, and Social (In)equity
Authors: Coppola William , Taylor Donald

Cultural humility has gained traction as a potentially transformative construct in social justice work, compelling practitioners to engage in a lifelong process of self-reflection and self-critique to recognize the limitations of their knowledge, practice openness toward others, and actively work to mitigate systemic inequities. In this paper, we draw theoretical interpretations from an empirical study of cultural humility as negotiated and developed through dialogues within a preservice music education course. By considering cultural humility through an iterative analysis of both empirical findings and theoretical perspectives, we propose that cultural humility comprises a fluid interrelation of intrapersonal, interpersonal, and transformative dimensions. We further articulate the significant internal struggles and challenges that emerged from this work as students navigated the various complications and contradictions that materialized through the process.
Valuing Racialized Student Voices: Transforming Learning Through Peer Mentoring
Authors: Goodrich Andrew
Published: May 2022

Although the practice of peer mentoring has had a place in education for many years, it has not routinely served as a platform for racialized students to use their voice in constructing their classroom learning. The history of music programs in the United States, with their dependence on Eurocentric music and disregard for the music of racialized persons, is a reminder that through the years, and continuing today, many programs only pay attention to some of the voices in the classroom. In this article, I investigate the promise that peer mentoring holds in equalizing the conversation. Although researchers have found many benefits in peer mentoring for racialized students and their teachers, their findings are contradictory and create paradoxes. These anomalies involve power structures in the classroom, othering of students, reproductive vs. transformational learning, and the potential for peer mentoring to reaffirm whiteness in school music programs. Drawing upon feminist pedagogy, with its collaborative construct of knowledge, inclusive sharing of experiences, and empowerment of all voices, I explore and critique how music teachers can use peer mentoring to create brave spaces for learning where racialized students share their knowledge and experiences while learning.
Coping with Discomfort: Understanding Pedagogical Decision-making as Coping with Social Change
Authors: Ocádiz Gabriela
Published: May 2022

The social tides of instability present in today’s world often require teachers to cope with social change in their pedagogical practices. Discomfort may be viewed as the beginning of a continuous critical reflective practice rather than a momentary emotive state: a way to see music education founded on an acceptance that nothing will be as it was, that nothing is ever supposed to remain static, and thus, no pedagogy is ever supposed to be the same for everyone. In this paper, I define coping with discomfort as a process of reflexivity that music teachers may already experience; it is continuous, incessant, and can help music teachers develop capacities to respond more actively to their students from diverse backgrounds.
Por una narratología transmedial
Authors: Baroni Raphaël , Lerma Hernández Cynthia
Published: May 2022

En una época en que la narratología se abre camino más allá del límite de los estudios literarios, este artículo plantea la necesidad de mantener un enfoque comparado de los medios que permita, por un lado, reconsiderar nociones fundamentales como la del narrador, el punto de vista, la focalización y, por otro, comprender las especificidades de cada medio en su manera de encarnar relatos. El texto expone asimismo la importancia, mediante este análisis comparativo, de definir los elementos fundamentales de la narratividad, cualquiera que sea la sustancia que transmita el relato. Atendiendo al lugar que goza la forma narrativa en nuestra sociedad, el artículo apuesta, dentro de un horizonte interdisciplinario, por una mejor comprensión general de las formas y las funciones de las producciones narrativas.

La minuciosa construcción del personaje Lucien de Rubempré en la Comédie humaine de Honoré de Balzac
Authors: Mejía Estévez Diego
Published: May 2022

Este artículo describe diversos elementos constituyentes del personaje Lucien de Rubempré: los paratextos que permiten comprender sus filiaciones, su faceta como artista literario, su experiencia como dandi y las interacciones que sostiene con otros personajes y que sellan su destino. Mediante el diálogo con propuestas teóricas y críticas específicas de entre las numerosas que han comentado Illusions perdues, en especial aquí del entorno italiano, se muestra cómo distintos aspectos del método realista tienen un vínculo estrecho con la construcción de este héroe y sus escenarios. Asimismo, la comparación con otras creaturas ficcionales del mismo sistema, es decir de la Comédie humaine, exponen con claridad las obsesiones del autor y las invariantes que imprimió a algunos personajes que se hicieron portavoces de su poética y visión de mundo. Se concluye al enfatizar, con diversos ejemplos, la complejidad y polivalencia de un héroe que sirve para establecer reflexiones metaliterarias y, sobre todo, enlazar los destinos y aventuras de otros personajes de primer orden en el universo de la Comédie.
“New phoenix wings”: el soneto “A John Keats (1795-1821)” de Jorge Luis Borges
Authors: Linares Gabriel
Published: May 2022

El presente artículo propone una lectura del soneto “A John Keats (1795-1821)” del poemario El oro de los tigres (1972) del escritor argentino Jorge Luis Borges (1899-1986). Dicho soneto fue escrito con motivo del ciento cincuenta aniversario de la muerte del último de los grandes románticos ingleses. Hasta ahora, las relaciones entre ambos autores se han centrado básicamente y de forma colateral en el ensayo “El ruiseñor de Keats”, del volumen Otras inquisiciones (1952). En este sentido, el artículo busca arrojar luz sobre un texto poco estudiado. La lectura ofrecida se centra en diversos aspectos del soneto. Para empezar, toma en cuenta la estructura métrica y argumentativa del poema en relación con su doble origen —el soneto en español y el soneto en inglés—. Estas consideraciones contribuyen a apreciar el poema en su complejidad estructural. Por otro lado, el artículo describe los medios de los que el soneto se vale para enunciar un elogio del individuo al que está dedicado. Dichos recursos, evidentemente, atañen a aspectos sintácticos y retóricos del texto, en primer lugar. No obstante, una parte importante de éstos es un rico conjunto de alusiones que recorren el poema de principio a fin y que vinculan el breve soneto no sólo con la obra de John Keats, sino con otros poetas británicos, como John Milton, George Gordon, Lord Byron o Matthew Arnold. En este sentido, el presente artículo es no sólo una contribución al estudio de las relaciones entre el autor argentino y el último romántico, sino una aproximación al análisis de las relaciones entre Borges y la lírica inglesa, tema poco trabajado hasta ahora.
As personagens de Ana Teresa Pereira: circularidade, enigma, segredo
Authors: Sousa Ana Rita
Published: May 2022

Este artigo pretende contribuir para o estudo da escritora portuguesa Ana Teresa Pereira, procurando acrescentar às análises já conhecidas da sua obra um estudo sobre alguns procedimentos narrativos que ajudam a esclarecer a produção do efeito enigmático que emana de cada um dos seus livros. Com este objetivo, o artigo começa por discutir a pertinência desta obra no contexto da literatura portuguesa, contrastando-a com a evidente falta de atenção mediática e até académica que mesmo tem sofrido. Neste âmbito, procura-se recolher o essencial da crítica especializada de forma a relacionar as dificuldades intrínsecas da leitura desta obra com a sua recepção, convocando as reflexões de Rui Magalhães, Fernando Guerreiro, Duarte Pinheiro e Amândio Reis. Num segundo momento, tenta-se destacar algumas ideias fundamentais herdadas de géneros literários relativamente pouco frequentados na literatura portuguesa: a narrativa policial e fantástica, utilizando, para o efeito, as reflexões de Jorge Luis Borges e Tzvetan Todorov, respectivamente. Num terceiro momento, realiza-se uma análise de As personagens (1990), segundo livro da autora, pensando-o a partir da perspectiva pigliana sobre conto e novela. Por último, demonstra-se que a poética de Ana Teresa Pereira pode ser compreendida, na sua obsessão labiríntica, como programática no sentido em que, além dos seus temas mais assinalados – a (im)possibilidade representação, o fantasma da identidade, a angústia do confronto – é possível compreender uma preocupação e reflexão profundas sobre a composição de um texto e de um livro.
Transustanciación de género en La montaña mágica de Thomas Mann
Authors: Alcántara Islas Omar
Published: May 2022

La siguiente lectura sobre La montaña mágica de Thomas Mann pretende una nueva interpretación de esta novela desde la perspectiva del gender —como acto performativo (Judith Butler)—, bajo la hipótesis de que el tema es central en el relato, al grado de que permite una interpretación que abarca los diversos aspectos de este; a la vez que el tema del gender, según este mismo análisis, posibilita repensar el concepto de Bildungsroman, como un género donde se incluye el mismo texto. Se habla de transustanciación porque existe en la obra una expresión de lo masculino y lo femenino en un equilibrio binario que, si bien reconoce la homosexualidad como algo presente en la novela y en la formación del protagonista, no se decantaría por esta debido a que eso afectaría la visión de un mundo bisexual implícito en la narración en una suerte de alquimia que propugna por una sustancia indefinible en relación con el gender. Tal condición también invita a una crítica de la triunfante y decadente heterosexualidad burguesa de la época donde es evidente que el gender es más fluctuante que lo que pretende esta sociedad.
An Overview on the Development and Research Work on Coconut Shell as An Aggregate
Authors: Ghosh Ishika
Published: May 2022

Abstract: Different waste materials such as fly ash, silica flumes, blast furnaces slag are used in concreting. Aggregate is a major ingredient for making concrete, occupy almost 70 - 80% part of concrete[1]. Conventionally crushed rocks are used as coarse aggregate and river sand used as fine aggregate. Due to rapid growth of construction activities, conventional aggregate sources are depleting very fast leading to significant increase in cost of Construction. This has necessitated research for alternative cost effective materials in construction. The paper aims about the partial replacement of crushed coconut shells as a substitute of conventional aggregate. It may help to produce concrete economically and at the same time also will help to reduce its disposal problem. Keywords: coconut shell, concrete, coarse aggregate, compressive strength, waste disposal.
Attendance Monitoring System Using Face Recognition

Abstract: The primitive method of taking attendance through pen-paper or registers by the organizations and institutions are not much efficient these days. The proxies of the absentees by their groups or friends are much common due to which this important factor of monitoring the class becomes ineffective. The pen-paper attendance system non-essentially consumes much time in class while smart techniques gives more time to lecturer. It can be simply be manipulated. So, for that many organizations and institutions have replaced it through biometric sensors which mark attendance through fingerprints of students or staff. But due to covid-19, where touching anything is risky. As we know in the current situation during covid-19 pandemic, Government of different nations have a strict guidelines for social distancing required to be followed everywhere keeping the aspect of safety measures in mind. For that, an attendance monitoring system has been devised through face recognition. This face recognition system works in the following stages - face detection, face pre-processing, database creation, face training, face recognition, attendance maintenance. This project spotlight on the significance of the face alignment, hence how precise image is and False Acceptance Rate that can be noticed. The system processes on Face Recognition Grand Challenge (FRGC) with up-to 95% precision. Few students do mark the fake attendance of their classmates by using their digital devices specially phone through which they try to show the picture of their friend to the system but in that case it will display warning message with a beep sound. The motive behind producing face-recognition system is to save the time and make system smart and efficient.
