Takotsubo cardiomyopathy (TCM) is a type of neuro cardiological disorder that evince as acute but reversible heart failure. On the whole, it occurs by stress-related cardiomyopathy which illustrates the heart-brain connection. It was first discovered in 1990, by a Japanese cardiovascular specialist. That's the beginning of this heart disease in gaining worldwide acceptance as an independent disease entity. TCM is entirely different from acute myocardial infarction as usually occurs in postmenopausal elderly women due to emotional or physical stress. It is characterized by transient hypokinesis of the left ventricular apex. However, there are complications too that need to be addressed. Some reports of serious TCM include hypotension, thrombosis involving LV apex, heart failure, and ventricular rupture. It is also suggested that coronary spasms, myocarditis, and coronary microvascular dysfunction might contribute to the pathogenesis of TCM. But in total, its pathophysiology is unclear. In this review article, we review the pathogenesis and etiology of this rare complex disorder along with its clinical features, findings, challenges in diagnosis, and a comprehensive discussion on the same.

Published: November 2022

Background: The “mid-day meal scheme” is the popular name for the school meal program of India, through which meal is provided to school children studying in the government and government aided schools. In non-government schools, children carry tiffin’s from home. Often, due to lack of time and/or knowledge of the parents and students, the contents of the food are not as per a balanced diet. The objective of the study was to analyse and compare the tiffin habits of primary and senior school children.Methods: This was a clinic-based study. Parents of 300 school going children were asked about tiffin habits of their children in a predesigned questionnaire. Data was analysed and conclusions drawn.Results: Most children carried tiffin to school on the majority of days. There was no statistical difference between primary or older children in their tiffin contents. Very few primary school children had a say in the content of tiffin. The senior students spent money in canteen on more days per week, whereas most primary class students spent only once a week or for treats.Conclusions: It is crucial for schools to establish food committees in school that suggests and   monitors tiffin policies and meal plans based on nutrition.

In terms of scale, shock, and disenfranchisement, the disruption to formal education arising from COVID-19 has been unprecedented. Anecdotally, responses from teachers and educators around the world range from heightened caution to being inspired by distance education as the “new normal.” Of all the challenges, face-to-face and formal teaching have been most heavily affected. Despite some education systems demonstrating resilience, a major challenge is sustaining quality and inclusiveness in formal education suddenly delivered at a distance. In probing these issues, this article profiles international perspectives on the role of open education in responding to the impact on formal school and higher education caused by the COVID-19 pandemic. We proceed by highlighting and analysing practices and case studies from 13 countries representing all global regions, identifying and discussing the challenges and opportunities that have presented themselves. Reports cover the period from the beginning of 2020 until 11 March 2021, the first anniversary of the COVID-19 outbreak as declared by the World Health Organization. In our comparative study, we identify seven key aspects of which three (missing infrastructure and sharing OER, open education and access to OER, and urgent need for professional development and training for teachers) are directly related to open education at a distance. After comparing examples of existing practice, we make recommendations and offer insights into how open education strategies can lead to interventions that are effective and innovative—to improve formal education at a distance in schools and universities in the future.
Open Distance and e-Learning: Ethiopian Doctoral Students’ Satisfaction with Support Services
Authors: Aberra Tsige GebreMeskel , Davids Mogamat Noor
Published: November 2022

This study assessed students’ level of satisfaction with the quality of student support services provided by an open distance e-learning (ODeL) university in Ethiopia. The target population was doctoral students who had been registered at the ODeL university for more than a year. To conduct a quantitative investigation, data were collected by means of a 34-item six-dimensional standardized questionnaire. Data analysis methods included linear as well as stepwise regressions. Using the gaps model as the theoretical framework, findings showed that the doctoral students were dissatisfied with four aspects of the student support services, namely supervision support, infrastructure, administrative support, and academic facilitation. In contrast, students were satisfied with the corporate image (reputation) of the ODeL university. For this ODeL university to play an effective role that coheres with the country’s socio-economic development plan, more attention should be given to the provision of supervision support, as there was strong dissatisfaction with this. The university could also build on or leverage aspects of their corporate image, for which there was strong satisfaction. Doing so will help the university make ongoing contributions and strengthen its commitment to the field of higher education and human capacity development in Ethiopia.

Published: November 2022

This cross-sectional study investigates the online education intention of undergraduate students in the largest and oldest public university in Bangladesh during the COVID-19 pandemic. Under convenient sampling, 843 undergraduate students with rural and urban backgrounds participated in an online self-administered questionnaire. Partial least squares structural equation modelling (PLS-SEM) was employed to examine the hypothesized relationships. We found that students’ online class intention is significantly influenced by their attitude towards online classes (AOC), perceived usefulness (PU), and facilitating conditions (FC). We further identified that external antecedents have significant indirect effects on the outcome variables. Our findings provide new insights and contribute to a learners’ community on online classes during the COVID-19 pandemic. This study extends the technology acceptance model (TAM) and the theory of planned behavior (TPB) to depict the factors influencing undergraduate students’ intention to attend online classes (IOC) during the COVID-19 pandemic.

Published: November 2022

Massive open online courses (MOOCs) have emerged as an affordable way to distribute knowledge and democratize education. The examination of online courses calls for theoretical models and instruments that contemplate its particularities. The community of inquiry (CoI) framework has been used in several studies to analyze the effectiveness of online education and hybrid education, including MOOCs. This study aimed to translate and validate the Community of Inquiry Survey instrument (Arbaugh et al., 2008) into Brazilian Portuguese, and used a two-stage methodological design for translating and validating a questionnaire. In the first stage, we carried out translation, back-translation, and cross-cultural adaptation. We translated the 34 items while maintaining the survey’s original format. In the expert evaluation phase, all items were considered understandable and essential for inclusion in the Brazilian Portuguese version of the CoI instrument. In the second stage, a prospective cross-sectional study was conducted to validate the questionnaire, and data was collected from participants completing the Nursing Assessment MOOC available on the Lúmina platform. A total of 690 responses were gathered. The resulting instrument produced excellent results, and the three presences achieved high reliability indexes, clearly indicating their adequacy. Furthermore, this study proved the validation of the CoI instrument, maintaining the three-factor structure previously reported in the literature corresponding to the three presences: teaching, social, and cognitive presence. We recommend further studies to evaluate the need for excluding or altering cognitive presence items.

Published: November 2022

The COVID-19 pandemic has caused a sudden shift to distance learning. For many nursing students, distance learning is a new experience and an essential requirement if they hope to complete their programs. Two challenges that nursing students could face during e-learning are the lack of social presence and low satisfaction. This study aimed to assess students’ sense of community and satisfaction during e-learning and determine their impacts on academic achievement. This cross-sectional descriptive study used convenience sampling to collect data via a student satisfaction survey and a classroom community scale. There was a positive and significant correlation between the sense of community, total satisfaction with e-learning (p < .001), and academic achievement (p < .001). Academic achievement was positively and strongly correlated with satisfaction with teaching (p < .001), assessment (p < .001), generic skills and learning experiences (p < .001), and total satisfaction with e-learning (p < .001). Students who worked collaboratively with their classmates and were more engaged in their learning were more satisfied with e-learning and had higher academic achievement (p < .01). Female participants reported a strong sense of community and satisfaction with e-learning and greater academic achievement than males. Junior students perceived higher satisfaction scores and greater academic achievement (p < .01) than senior students. The findings of this study suggest that failing to meet student expectations can lead to low levels of student involvement. Students’ engagement and satisfaction are good indicators of the quality and effectiveness of online programs.
A Learning Analytics Approach Using Social Network Analysis and Binary Classifiers on Virtual Resource Interactions for Learner Performance Prediction
Authors: Khor Ean Teng , Darshan Dave
Published: November 2022

The COVID-19 pandemic induced a digital transformation of education and inspired both instructors and learners to adopt and leverage technology for learning. This led to online learning becoming an important component of the new normal, with home-based virtual learning an essential aspect for learners on various levels. This, in turn, has caused learners of varying levels to interact more frequently with virtual resources to supplement their learning. Even though virtual learning environments provide basic resources to help monitor the learners’ online behaviour, there is room for more insights to be derived concerning individual learner performance. In this study, we propose a framework for visualising learners’ online behaviour and use the data obtained to predict whether the learners would clear a course. We explored a variety of binary classifiers from which we achieved an overall accuracy of 80%–85%, thereby indicating the effectiveness of our approach and that learners’ online behaviour had a significant effect on their academic performance. Further analysis showed that common patterns of behaviour among learners and/or anomalies in online behaviour could cause incorrect interpretations of a learner’s performance, which gave us a better understanding of how our approach could be modified in the future.
SLOAN: Social Learning Optimization Analysis of Networks
Authors: Lemay David , Doleck Tenzin , Brinton Christopher
Published: November 2022

Online discussion research has mainly been conducted using case methods. This article proposes a method for comparative analysis based on network metrics such as information entropy and global network efficiency as more holistic measures characterizing social learning group dynamics. We applied social learning optimization analysis of networks (SLOAN) to a data set consisting of Coursera courses from a range of disciplines. We examined the relationship of discussion forum uses and measures of network efficiency, characterized by the information flow through the network. Discussion forums vary greatly in size and in use. Courses with a greater prevalence of subject-related versus procedural talk differed significantly in seeking but not disseminating behaviors in massive open online course discussion forums. Subject-related talk was related to higher network efficiency and had higher seeking and disseminating scores overall. We discuss the value of SLOAN for social learning and argue for the experimental study of online discussion optimization using a discussion post recommendation system for maximizing social learning.

ABSTRACTBackground: Bioactive composite resin has known as smart materials, because it can react to the pH cycle in oral cavity which can be caused by consumption of acidic foods and drinks. The drinks that are often consumed by people and contain acid are probiotic drink and orange juice drink. Changes in the oral cavity pH that turn into acid cause the bioactive composite resin to release calcium, fluorine, and phosphate ions as tooth remineralization factors. Purpose: to analyze the amount of calcium ion release in bioactive composite resin after soaking in probiotic drinks and orange juice. Methods: This study was divided into three groups of composite resin immersion as follows immersion in probiotic drinks, orange juice drinks, and artificial saliva (as a control group). The sample was crushed using a mortar until smooth then given some indicator solution and heated until a precipitate was formed then the weight of Ca was calculated. Results: The Kruskall Wallis test and Mann Whitney test showed that there were significant differences in all treatment groups (p <0.05). Conclusion: Exposure to probiotic drinks, orange juice, and artificial saliva showed that the amount of calcium ion release from composite resin had significant differences.Keywords: bioactive, calcium, composite resin, orange juice, probiotic.ABSTRAKLatar belakang: Resin komposit bioaktif dikenal sebagai smart materials, karena dapat bereaksi terhadap siklus pH yang ada dalam rongga mulut yang dapat disebabkan oleh konsumsi makanan dan minuman yang bersifat asam. Minuman yang sering dikonsumsi masyarakat dan mengandung asam adalah minuman probiotik dan minuman sari jeruk. Perubahan pH di dalam rongga mulut yang berubah menjadi asam menyebabkan resin komposit bioaktif melepaskan ion kalsium, ion fluor, dan ion fosfat sebagai faktor remineralisasi pada gigi.   Tujuan: untuk menganalisis jumlah pelepasan ion kalsium pada resin komposit bioaktif setelah direndam minuman probiotik dan sari jeruk. Metode: Penelitian ini terbagi menjadi tiga kelompok perendaman resin komposit yaitu direndam pada minuman probiotik, minuman sari jeruk, dan pada saliva buatan (kelompok kontrol). Sampel digerus menggunakan mortar hingga halus kemudian diberikan beberapa larutan indikator dan dipanaskan sampai terbentuk endapan kemudian dilakukan penghitungan berat Ca. Hasil: Uji Kruskall Wallis menunjukkan bahwa terdapat perbedaan yang bermakna pada jumlah pelepasan ion kalsium pada setiap kelompok (p <0.05). Uji Mann Whitney menunjukkan terdapat perbedaan bermakna pada semua kelompok perlakuan (p <0.05). Kesimpulan: Paparan minuman probiotik, sari buah jeruk, dan saliva buatan menunjukkan jumlah pelepasan ion kalsium resin komposit yang memilili perbedaan bermakna.Kata kunci: bioaktif , kalsium, prebiotik, resin komposit, sari jeruk
