Unmuting Medical Students’ Education: Utilizing Telemedicine During the COVID-19 Pandemic and Beyond (Preprint)
Authors: Iancu Ariella Magen , Kemp Michael Thomas , Alam Hasan Badre
Published: April 2020

UNSTRUCTURED

Due to the coronavirus disease (COVID-19) pandemic, medical schools have paused traditional clerkships, eliminating direct patient encounters from medical students’ education for the immediate future. Telemedicine offers opportunities in a variety of specialties that can augment student education during this time. The projected growth of telemedicine necessitates that students learn new skills to be effective providers. In this viewpoint, we delineate specific telehealth opportunities that teach core competencies for patient care, while also teaching telemedicine-specific skills. Schools can further augment student education through a variety of telemedicine initiatives across multiple medical fields. The explosion of telemedicine programs due to the pandemic can be a catalyst for schools to integrate telemedicine into their current curricula. The depth and variety of telemedicine opportunities allow schools to continue providing high-quality medical education while maintaining social distancing policies.

Spattering effects during selective laser melting
Authors: Volpp Joerg
Published: April 2020

Additive manufacturing using preplaced powder became a widely used processing method during the last few years to build complex and precise structures. The laser beam is often used as a heat source to selectively melt the powder and create the structure layer by layer. However, during the processing, imperfections can occur. The spattering, accumulation of powder particles, and denudation effects lead to a redistribution of the powder in the powder bed, a loss of powder, and agglomerations. These effects can alter the processing of the subsequent tracks and layers. On the one hand, the track dimensions can vary by varied amounts of available powder. On the other hand, the process can become unstable due to different powder surface geometries, agglomerates, and the resulting variation of energy absorption. Therefore, this work aims to explain spattering effects during powder-bed processing, which can be used for modification of the processing parameters for spatter prevention. High-speed-imaging was used to record the powder and spatter behavior during the laser powder-bed processing from different angles. It was observed that different kinds of spattering can occur. Melt pool spattering occurs due to melt instabilities, while powder particles seem to be accelerated by vapor induced gas movement, pressure waves, and the gas flow induced by the Bernoulli-effect.
Influence of hydrogen, oxygen, nitrogen, and water vapor on the formation of pores at welding of copper using laser light at 515 nm wavelength
Authors: Alter Lukas , Heider Andreas , Bergmann Jean Pierre
Published: April 2020

Due to increased absorptivity of laser light at 515 nm wavelength in copper materials, welds with low formation of spatters and homogeneous weld depths can be performed.1 However, depending on the used process parameters, a process regime with strong formation of pores is observed. These pores are not resulting from instabilities of the capillary (process pores), but they are observed to result from the interaction of ambient gas with the melted material in the welding zone. Different gaseous elements such as nitrogen, hydrogen, oxygen, and water vapor, therefore, were applied to the welding process to investigate their influence on the resulting weld seam porosity. For this purpose, all welds were performed in a welding chamber. It is found that the reaction of ambient nitrogen with ambient oxygen during the welding process has a strong influence on the resulting weld seam porosity. Furthermore, pores are observed in the weld seam when the raw copper material contains an increased amount of oxygen. Depending on which copper material is used, strategies are derived to perform welds with low or no formation of pores.
Mathematical modeling of the geometrical differences between the weld end crater and the steady-state weld pool
Authors: Artinov Antoni , Karkhin Victor , Bachmann Marcel , Rethmeier Michael
Published: April 2020

The geometrical characteristics of the weld end crater are commonly used as a means of validating numerical results in welding simulations. In this paper, an analytical model is developed for calculating the cooling stage of the welding process after the moving energy source is turned off. Solutions for various combinations of heat sources and heated bodies are found. It is shown that after turning off the energy source, additional melting of the base material in the longitudinal direction may occur due to the overheated liquid metal. The developed technique is applied to complete-penetration keyhole laser beam welding of 2 mm thick austenitic stainless-steel plate 316L at a welding speed of 20 mm s−1 and a laser power of 2.3 kW. The results show a theoretical increase in the weld end crater length of up to 19% compared to the length of the steady-state weld pool. It is found that at the moment of switch off, the weld end crater center, where solidification of the liquid metal ends, is shifted from the heat source axis toward the weld pool tail. The solidification rate and the direction of crystallization of the molten material during the welding process and those in the weld end crater differ significantly. A good agreement between the computational results and the welding experiments is achieved.
Image-based algorithm for nozzle adhesion detection in powder-fed directed-energy deposition

Published: April 2020

The rapidly growing technological innovation of directed energy deposition leads to an increase in part complexity as well as quality and mechanical properties of manufacturable components. However, the variety of process parameters and influencing factors still requires skilled operators, who observe the machine tools. For an unobserved use of deposition welding machines, well parametrized and validated monitoring systems have to analyze the process to detect irregularities and finally initiate a machine stop. This study focuses on nozzle adhesions that frequently occur when tool or high-speed steels are processed. This effect leads to decreasing quality or ultimately to a failure of the whole welding process. In this work, the authors present an algorithm and the corresponding parametrization to automatically detect nozzle adhesions based on images from a coaxial camera, integrated in the laser head. The algorithm is based on a detailed image analysis from which temporal and spatial patterns are derived. In particular, the algorithm calculates a nozzle adhesion indicator based on the heat intensity distribution in an experimentally derived shaped area on the inner nozzle boundary. It is parametrized in such a way that process-critical adhesions are detected. The algorithm was parametrized using an experimental setup with four materials: stainless steel (X2CrNiMo17-12-2), tool steel (X35CrMoMn7-2-1), high-speed steel (HS6-5-2C), and the nickel-based alloy NiCr19NbMo.

The Relationship between Employability Skills and Self-Efficacy of Students With Learning Disabilities In Vocational Stream
Authors: Ab Halim Fazlinda , Wan Muda Wan Hanim Nadrah , Izam Saslizawati
Published: April 2020

Nowadays, the unemployment among special needs students with learning disabilities is getting worse in Malaysia. Societies are always not confident of the employability skills of people with special needs, as the former do not believe that the latter could work efficiently. Since they are often associated with low self-confidence, the capabilities of people with special needs are often in doubt, and their self-efficacy is also open to question. Self-efficacy is included in the environmental factors that contribute to the degree of skilfulness. Therefore, this study aims to explore the level of employability skills and self-efficacy of students with learning disabilities, and determine the relationship between the two variables. This quantitative survey research was conducted at the Indahpura Special Education Vocational Secondary School, Kulai, Johor. About 60 students from four courses were recruited for the purposed of this study. An instrument was adapted with minor modifications from the Secretary's Commission on Achieving Necessary Skills (SCANS) to study the employability skills and The General Self-Efficacy Scale (GSE) to study the self-efficacy. Data were analysed using the Statistical Package for Social Science Version 19.0 (SPSS 19) to obtain the frequency, mean, standard deviation, percentage and correlation between the variables. The results show that employability skills and self-efficacy of the students with special needs are at a moderate level. The findings of the study reveal that there is a strong positive relationship between self-efficacy and the student’s employability skills. In conclusion, special education students with learning disabilities have room for improving their employability skills, and they can do it through these avenues: attend entrepreneurship programmes, participate in community services, and undergo self-improvement courses as well as practical training in relevant agencies. Societies are duty-bound to provide continual guidance to the students with special needs so that they can be a useful, and competitive work force to serve the country.

In line with Malaysia Education Blueprint (Higher Education) 2015-2025, the implementation of Integrated Cumulative Grade Point Average (iCGPA) for Diploma in Public Administration (DPA) in the Faculty of Administrative Science and Policy Studies (FSPPP), Universiti Teknologi MARA (UiTM) was started in July - October 2016 academic session. Hence, there is a need to evaluate the implementation of the iCGPA attainment. Therefore, this paper aims to examine the iCGPA achievement of the first cohort of the DPA students based on their examination and academic performance. Results from the first iCGPA cohort in DPA were analysed and compared to produce a report on the iCGPA evaluation. The findings had revealed that the DPA students were able to attain better GPA and CGPA and a lower percentage of failure rates. In addition, the findings had revealed that the faculty was able to meet its academic Key Performance Indicators (KPI). Indeed, throughout the iCGPA implementation, students were able to reach grade B and A+ for all the nine (9) learning outcomes proposed in iCGPA. To monitor the results, the faculty has developed the iCGPA Reporting Card (iRC) in 2017 which aims to assess the attainment of Program Learning Outcomes (PLOs) to monitor the continuous improvement efforts in teaching and learning and a friendly user reporting card in reporting the overall undergraduate academic programme achievement (iCGPA). It was suggested that iCGPA is to be continued at diploma levels with proper modifications and should be extended to all UiTM campuses which offer DPA programme.

Perceived View of Teachers Towards Pentaksiran Tingkatan Tiga (PT3) (Form Three Assessment) English Language: A Case Study
Authors: Sabbir Fatima
Published: April 2020

The Standard-Based Curriculum for Secondary Schools (KSSM) was introduced in secondary schools in 2017. Parallel to the changes in the curriculum, Malaysian ESL (English as a Second Language) was revised to align with the Common European Framework of References (CEFR). Similarly, there is a change in the assessment of form three students. Therefore, this study aims to identify the perceived view of teachers towards ‘Pentaksiran Tingkatan Tiga’ (PT3) (Form Three Assessment) English Language. A qualitative research method using snowball sampling was employed in obtaining the data. This study is designed based on a case study approach. Five TESL (Teaching English as Second Language) teachers were interviewed by using open-ended questions to ascertain their perceived view on the PT3 English language. The findings show that the teachers were generally positive on the CEFR-aligned PT3 English language. However, the teachers indicated that the teaching of CEFR-aligned English language in an ESL classroom must be tailored by the teachers according to the proficiency levels of the students. This study also illustrated that teachers faced challenges of facilities and relevant materials in assessing the students. Further research should employ a larger sample size to obtain a broader perspective on the perceived view of teachers towards PT3 English Language.

Practitioners’ Views on Learning Using Children’s Peer Interactions Amongst Under Three Year Old Children in Selangor, Malaysia
Authors: Wan Yunus Farhana
Published: April 2020

Research on children’s peer interactions shows many benefits for children’s development especially in developing children’s social competence. Drawing on a case study data from a study that investigated peer interactions among under-three-year-old children in three Malaysian childcare centres, this paper provides a picture of how the children’s peer interactions were understood by largely untrained practitioners at the start of the project, and how the complexity of children’s lived experiences remained hidden to the practitioners until they took part in the video-stimulated recall (VSR) interviews based on children’s peer interactions, and focus group discussions. The latter provided practitioners with an opportunity to deepen their thinking about children’s peer interactions and to begin to see them as linked with learning. In particular, the practitioners perceived that (i) play; (ii) familiarity; and (iii) having friends constituted important learning for children during peer interactions at their early childcare centres. This has implications for understanding the roles of early childhood education practitioners to children’s peer interactions as well as how practitioners can help support children’s learning to make a social difference.

Published: April 2020

Teaching in an era dominated by millennials represents a challenging task for educators in Institutes of Higher Learning (IHLs). One distinct feature in teaching millennials is the advancement in digital learning which has improved learning styles in higher education. Besides face-to-face interactions with the instructors, the blended learning approach has been introduced in many courses to cater to the needs of millennial learners. This study aims to provide an insight into on students’ acceptance and satisfaction towards the use of Learning Management System (LMS) in a blended learning environment. An online survey was administered to 167 respondents. The majority of the respondents are below 22 years of age and first-year students who are fresh and new to the blended learning concept. This study measured factors like technology experience, computer anxiety, service quality, system quality, information quality, course quality, and instructor to determine the students’ overall satisfaction. The model was analysed using the partial-least-squares structural modeling approach. The result shows that service quality, instructor quality, and course quality are among the critical factors towards students’ acceptance and satisfaction. Therefore, to ensure LMS’s effectiveness and students’ satisfaction, decision-makers at the higher institution should consider these factors before implementing a blended learning initiative via LMS as the platform.

Atrial fibrillation is the most prevalent arrhythmia in the world population. Despite the use of antiarrhythmics, it is difficult to control clinically, causing symptoms and mainly generating risk of a thromboembolic event. Since 1998, by means of radiofrequency ablation, the treatment of atrial fibrillation has completely changed, but together with this important evolution complications from this ablative treatment technique have also started. In addition to the pulmonary vein stenosis caused by the ablation and later corrected with the change in the technique, atrioesophageal fistulas appeared due to the application of radiofrequency in the posterior wall of the left atrium. This wall is very close (0.5 cm onaverage) to the esophagus, which facilitates the formation of the fistula that leads to the death of almost 100% of the affected patients, despite the various treatment measurements already developed. To avoid this serious complication, several authors have created techniques to protect the esophagus including its mechanical deviation to a region opposite to the radiofrequency application, taking advantage of its mobility and easiness of handling. The mechanical deviation of the esophagus has proven to be the simplest, cheapest and most efficient way to protect this organ from radiofrequency thermal damage during atrial fibrillation ablation.

Published: April 2020

The article presents research data from 2004-2009. The creativity of younger school-age children was examined. There has been a pattern here; the age of the child increases creativity decreases. The study was repeated in 2019. This time we got some interesting data. Creativity decreases at the beginning of junior school age, but increases at the end of age. I think this explanation should be explored, but the only change in the Armenian educational system is the introduction of the "Chess" subject. We believe that it has had a positive impact on the development of children's creativity.

Authors: Parkinson Lily A. , Mans Christoph
Published: April 2020

OBJECTIVE

To evaluate the effects of 3 electrolyte solutions administered SC to experimentally dehydrated inland bearded dragons (Pogona vitticeps).

ANIMALS

9 inland bearded dragons.

PROCEDURES

In a randomized, complete crossover study, experimental dehydration was induced by means of furosemide (10 mg/kg, SC, q 12 h for 4 doses), and then lactated Ringer solution, Plasma-Lyte A, or reptile Ringer solution (RRS; 1:1 mixture of 5% dextrose solution and isotonic crystalloid solution) was administered SC in a single 50-mL/kg dose in 3 treatments sessions separated by a minimum of 14 days. Food and water were withheld during treatment sessions. Plasma biochemical values, PCV, blood total solids and lactate concentrations, and plasma osmolarity were measured prior to (baseline) and 4 and 24 hours after fluid administration.

RESULTS

Administration of RRS resulted in severe hyperglycemia (mean ± SD plasma glucose concentration, 420 ± 62 mg/dL), compared with baseline values (190 ± 32 mg/dL), and this hyperglycemia persisted for at least 24 hours. It also resulted in significant reductions in plasma osmolarity and sodium and phosphorus concentrations, which were not observed after administration of the other 2 solutions. Administration of lactated Ringer solution caused no significant increase in blood lactate concentration.

CONCLUSIONS AND CLINICAL RELEVANCE

The changes in plasma glucose, sodium, and phosphorus concentrations and plasma osmolarity observed after SC administration of a single dose of RRS suggested this type of electrolyte solution should not be used for rehydration of bearded dragons. Rather, lactated Ringer solution or Plasma-Lyte A should be considered instead.
On determining the undrained bearing capacity coefficients of variation for foundations embedded on spatially variable soil
Authors: Chwała Marcin
Published: April 2020

This paper presents an efficient method and its usage for the three-dimensional random bearing capacity evaluation for square and rectangular footings. One of the objectives of the study is to deliver graphs that can be used to easily estimate the approximated values of coefficients of variations of undrained bearing capacity. The numerical calculations were based on the proposed method that connects three-dimensional failure mechanism, simulated annealing optimization scheme and spatial averaging. The random field is used for describing the spatial variability of undrained shear strength. The proposed approach is in accordance with a constant covariance matrix concept, that results in a highly efficient tool for estimating the probabilistic characteristics of bearing capacity. As a result, numerous three-dimensional simulations were performed to create the graphs. The considered covariance matrix is a result of Vanmarcke’s spatial averaging discretization of a random field in the dissipation regions to the single random variables. The matrix describes mutual correlation between each dissipation region (or between those random variables). However, in the presented approach, the matrix was obtained for the expected value of undrained shear strength and keep constant during Monte Carlo simulations. The graphs were established in dimensionless coordinates that vary in the observable in practice ranges of parameters (i.e., values of fluctuation scales, foundation sizes and shapes). Examples of usage were given in the study to illustrate the application possibility of the graphs. Moreover, the comparison with the approach that uses individually determined covariance matrix is shown.

Cellulose had been isolated from rice husk waste and sawdust with chemical method through hydrolysis with HCl 2.5 N and bleaching process with  H2O23%.The yields were 13,45% and 22,75% (w/w) of cellulose from rice husk waste and sawdust, respectively. The chemical treatment caused partial removal of lignin and hemicellulose from raw material showed by FTIR spectrum.  Structure and morphology of cellulose from rice husk waste and sawdust were investigated using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD patterns showed cellulose structure converted from amorphous to crystalline form after bleaching process while SEM images showed that the isolated cellulose from rice husk waste had rougher surface than cellulose from sawdust. The SEM micrograph also showed that the isolated cellulose from rice husk was in the form of aggregates.

Chlamydophila abortus, tüm dünyada koyun ve keçilerde ciddi ekonomik kayıplara yol açan, koyunların enzootik abortusunun (OEA) etkenidir. Bu çalışmanın amacı, Türkiye’nin Burdur ilinde keçi sürülerinde C. abortus enfeksiyonunun seroprevalansını ortaya koymaktı. 384 kan serum örneği, rastgele seçilen 22 keçi sürüsünde, 2 ve daha büyük yaşlardaki keçilerden toplandı. C. abortus enfeksiyonunun bireysel, sürü içi ve sürüler arası seroprevalansı, ticari bir enzyme linked immunosorbent assay (ELISA) kiti ile belirlendi. C. abortus’un görünen ve gerçek bireysel, sürü içi ve sürüler arası seroprevalansı sırasıyla 19.27%, 22.77%, 86.36% ve 19.44%, 23.16%, 90.81% olarak hesaplandı. Sürü büyüklüğüne göre C. abortus enfeksiyonunun seropozitifliği bazı sürüler arasında istatistiki olarak önemli (p˂0.05) bulundu. Keçi ırkları ile C. abortus enfeksiyonu arasındaki ilişki önemli bulunmadı (p˃0.05).

“About my defiled, beloved Russia I yearn in a foreign land…”: revolution and civil war in reminiscences of the countess P. S. Uvarova
Authors: Petrova Olga Sergeevna
Published: April 2020

This article examines the reflection of events of the period of civil war and intervention in the memoirs of the countess P. S. Uvarova “The Past. Long Gone Happy Days”. These reminiscences are the testimonies of a witness on people and events of the late XIX – early XX century that allow understanding the life of academic community from inside, the routine of professional historians and amateur regional ethnographers. On the other hand, the narrative about the last years in the native country allow viewing the everyday life of Uvarovs family in the conditions when the routine has been destroyed. Reference to the personal sources revealing the new pages and milestones of the phenomenon in question allows seeing it through the eyes of a person from the past, find out what was happening and what felt the author. The peculiarity of P. S. Uvarova’s memoirs consists in focusing not on the everyday minutiae that is common to women, but on the reasoning which purpose is to preserve and translate the representations on the core values of life that were relentlessly destroyed by the revolution to the future generations.
Pengaruh Tenure CEO terhadap Readability Narasi Pengungkapan
Authors: Ainun Moh. Baqir
Published: April 2020

This study examines the influence of CEO tenure on readability of narratives disclosure. This study also included company size and company age as control variables. The sample used in this study was 482 companies listed on the Indonesia Stock Exchange in 2018. There are not many studies on readability of narratives disclosure in Indonesia, so this study is expected to motivate academics to develop studies on disclosure narrative readability. The results showed that more longer CEO tenure could increase the readability of narratives disclosure. This condition can occur because CEO with longer tenure will be better able to communicate firm conditions in naratives disclosure that is simpler and easier to understand than CEO with shorter tenure. Moreover, firm size and firm age add complexity to narratives disclosure and decrease readability. This condition occurs because more larger the firm size and more older the firm age can create more items that must be disclosed in the narratives disclosure. This study can use to enrich the literature about influence of CEO tenure on readability of narratives disclosure.

Maximum diversification of data is a central theme in building generalized and accurate machine learning (ML) models. In chemistry, ML has been used to develop models for predicting molecular properties, for example quantum mechanics (QM) calculated potential energy surfaces and atomic charge models. The ANI-1x and ANI-1ccx ML-based eneral-purpose potentials for organic molecules were developed through active learning; an automated data diversification process. Here, we describe the ANI-1x and ANI-1ccx data sets. To demonstrate data set diversity, we visualize them with a dimensionality reduction scheme, and contrast against existing data sets. The ANI-1x data set contains multiple QM properties from 5M density functional theory calculations, while the ANI-1ccx data set contains 500k data points obtained with an accurate CCSD(T)/CBS extrapolation. Approximately 14 million CPU core-hours were expended to generate this data. Multiple QM properties from density functional theory and coupled cluster are provided: energies, atomic forces, multipole moments, atomic charges, and more. We provide this data to the community to aid research and development of ML models for chemistry.
