Authors: Li Chi-Ping , Chuang Chih-Min
Published: August 2021

Thermal and dielectric properties of rigid-rod bifunctional epoxy resin 4,4-bis(2,3-epoxypropoxy) biphenyl epoxy (BP) and commercial epoxy resin diglycidyl ether of bisphenol A (DGEBA) were studied using differential scanning calorimeter (DSC), thermogravimetric analyzer (TGA), dynamic mechanical analyzer (DMA), thermal mechanical analyzer (TMA) and dielectric analyzer (DEA). These two epoxies were cured with cyanate ester hardener 2,2’-bis(4-cyanatophenyl) propane (AroCy B10). The BP/B10 system consisting of a rigid-rod structure exhibited better thermal properties than the DGEBA/B10 system with a flexible structure. Anisotropic BP/B10 (2:1) had the highest 5% weight loss temperature, the highest amount of residue and a smaller thermal expansion coefficient than the commercial DGEBA/B10 system. The BP/B10 system, which cured at the LC phase temperature, had higher Tg than the commercial DGEBA/B10 system, as found from dynamic mechanical analysis. The BP/B10 system also demonstrated better dielectric properties than the commercial DGEBA/B10 system when enough curing agent was provided.
Using the Blind Spot to Investigate Trans-Saccadic Perception

Published: August 2021

We introduce a blind spot method to create image changes contingent on eye movements. One challenge of eye movement research is triggering display changes contingent on gaze. The eye-tracking system must capture the image of the eye, discover and track the pupil and corneal reflections to estimate the gaze position, and then transfer this data to the computer that updates the display. All of these steps introduce delays that are often difficult to predict. To avoid these issues, we describe a simple blind spot method to generate gaze contingent display manipulations without any eye-tracking system and/or display controls.

Authors: Alanazi Khalid H. , Alqahtani Mohammed , Humayun Tabish , Alanazi Adel , Aldecoa Yvonne S. , Alshanbari Nasser , El-Saed Aiman , Bin Saleh Ghada
Published: August 2021

Background: Although the Saudi Ministry of Health (MOH) is managing the majority of inpatient bed capacity in Saudi Arabia, surveillance data for central-line-associated bloodstream infections (CLABSI) have never been reported at a national level. Objectives: To estimate unit-specific CLABSI rates along with central line utilization ratios in MOH hospitals. Additionally, to benchmark such rates and ratios with recognized regional and international benchmarks. Methods: A prospective surveillance study was conducted in 106 MOH hospitals between January 2018 and December 2019. The data from 14 different types of intensive care units (ICUs) were entered into the Health Electronic Surveillance Network (HESN) program. The surveillance methodology was similar to the methods of the US National Healthcare Safety Network (NHSN) and the Gulf Cooperation Council (GCC) Center for Infection Control. Results: During the 2 years of surveillance in ICU setting covering 1,475,177 patient-days and 475,913 central line-days, a total of 1,542 CLABSI events were identified. The overall CLABSI rate was 3.24 (95% confidence interval [CI], 3.08–3.40) per 1,000 central line-days, and the overall central line utilization ratio was 0.32 (95% CI, 0.322–0.323). CLABSI-standardized infection ratios in HESN hospitals were very similar (1.01) to GCC hospitals, but 3.2 times higher than NHSN hospitals and 36% lower than International Nosocomial Infection Control Consortium (INICC) hospitals. Central-line-standardized utilization ratio in MOH hospitals was 15–30% lower than the three benchmarks. Conclusions: The overall CLABSI rate was 3.24 per 1,000 central line-days, and the overall central line utilization ratio was 0.32. MOH CLABSI rates were very similar to GCC hospitals, but higher than NHSN hospitals and lower than INICC hospitals. MOH central line utilization is slightly lower than the three benchmarks.

Authors: Da Silva Verdoorn Karine , Rocha Mendonça Henrique
Published: August 2021

A COVID-19 consolidou-se como a principal pandemia dos últimos cem anos, tornando-se a principal causa de morte no Brasil e no mundo. Os sistemas de saúde, bem como as fontes de financiamento de pesquisas científicas voltaram seus holofotes para desenvolver estratégias de prevenção da disseminação do vírus Sars-Cov 2 e tratamento da COVID-19. Nesse cenário, o uso de máscaras para prevenir o contágio foi uma das principais estratégias adotadas pelos governos e sistemas de saúde. Apesar de estudos comprovarem a eficácia dessa metodologia para prevenir a infecção por vírus respiratórios, a segurança do seu uso não foi amplamente testada na população, de forma que grupos de risco não foram identificados. Assim, esse artigo se propõe a discutir a segurança do uso de máscaras pelas pessoas com epilepsia, que comprovadamente apresentam propensão a sofrer crises quando submetidos a alterações da fisiologia respiratória.

In response to this phenomenon, this program aimed to deliver a leadership development program based on Islamic values to the management of LPP UMI Makassar’s OSIS board. Research Methodology: This internal community service method combines lecture, discussion, and evaluation approaches to achieve the best results. The evaluation technique is collected through questionnaires covering elements pertaining to Islamic leadership based on Nabi Muhammad SAW. This questionnaire was then issued to ascertain their level of comprehension of the material presented. This program attracted 27 students, representing 81.8 percent of the total student council board of SMA LPP UMI, Makassar. Results: The program’s findings indicated that participants better understood the concepts and attributes of leadership in the Islamic paradigm. In addition, the results also showed that the dimension of Sidiq’s character (honesty) has the highest average score (4.48), meaning that the students of LPP UMI Makassar consider honesty as the most important thing that leaders must have in the concept of Islam. Conclusion: This outcome is designed to instill an Islamic leadership attitude in SMA UMI’s student council students, enabling them to contribute positively to Indonesia in the future.
A Technique for Approximate Communication in Network-on-Chips for Image Classification
Authors: Chen Yuechen , Liu Shanshan , Lombardi Fabrizio , Louri Ahmed
Published: August 2021

Approximation is an effective technique for reducing power consumption and latency of on-chip communication in many computing applications. However, existing approximation techniques either achieve modest improvements in these metrics or require retraining after approximation, such when convolutional neural networks (CNNs) are employed. Since classifying many images introduces intensive on-chip communication, reductions in both network latency and power consumption are highly desired. In this paper, we propose an approximate communication technique (ACT) to improve the efficiency of on-chip communications for image classification applications. The proposed technique exploits the error-tolerance of the image classification process to reduce power consumption and latency of on-chip communications, resulting in better overall performance for image classification computation. This is achieved by incorporating novel quality control and data approximation mechanisms that reduce the packet size. In particular, the proposed quality control mechanisms identify the error-resilient variables and automatically adjust the error thresholds of the variables based on the image classification accuracy. The proposed data approximation mechanisms significantly reduce packet size when the variables are transmitted. The proposed technique reduces the number of flits in each data packet as well as the on-chip communication, while maintaining an excellent image classification accuracy. The cycle-accurate simulation results show that ACT achieves 23% in network latency reduction and 24% in dynamic power reduction compared to the existing approximate communication technique with less than 0.99% classification accuracy loss.
A Method of Joining Piecewise Functions to Produce Continuous Functions of Difficult Data
Authors: Orszulik Stefan
Published: August 2021

This article describes a method of modelling
data that involves splitting the curve into two (or more) and creating separate
piecewise functions for each part; these functions are then concatenated via a
linking function to create one overall continuous function that better
describes the original data than is otherwise achievable. The linking function
is able to do this by separating the original two (or more) subfunctions so
that they are each active in only the relevant portion of the overall curve
without the use of dummy variables. The final result is a continuous function
in which it is straightforward to smooth the transition at the knot between the
piecewise subfunctions. In addition, the piecewise subfunctions do not need to
align at the knot since the degree of smoothing is readily controlled. All
types of functions may be concatenated so that the method is flexible and
relatively simple to apply.

Project Based Learning (PBL) is a very popular teaching strategy nowadays because it offers a great number of advantages and/or opportunities from a teaching point of view, such as achieving a deeper learning, developing teamwork and leadership skills, or getting the student to take control of what and how to learn. For all these reasons, the authors believe that, in the context of the Master's studies, as the last studies before insertion into working life, the PBL can be a very appropriate teaching methodology, since well thought out it will prepare students for the real situations that they will later experience in their professional lives. The objective of this workis to present the experience of the application of PBL in the development of a common project for four subjects of the University Master in Engineering, Processing and Characterization of Materials, taught at the Polytechnic School of Alcoy, belonging to the Polytechnic University of Valencia (UPV).

This chapter is drawn from a PhD study that employedStudent Team’sAchievement Divisions as a learning technique to enhance learners’ intrinsic motivation inTechnology Education within a South African multicultural school. The authors over the years observed learners’ actions, and interactions in Technology classes and realised that some of the learners find it difficult to engage in behaviour that arises within themselves -an aspect known as intrinsic motivation. Most learners in the Technology class, registered no concerns in obtaining low scores or failing the subject. However, a minority of the learner population obtained high achievement scores and maintained interest throughout lessons. This study explored the development of the ZPD in a cooperative learning context. The authorsusedSTAD, as a cooperative learning technique, in motivating learners intrinsically to increase their participation in class activities. The study explored STAD in1) closing the gap between pedagogy and content knowledge, and 2) intrinsically motivating learners to develop high levels of achievement in the subject of Technology. This study employed the Bricolage design in gathering data from two Grade eight Technology classes over a six-month period. The findings indicated that the learning environment cultivated learners’ development, curiosity, and positive attitude toward Technology.

The study investigates the differences in nursing and engineering students’ perceptions of videos made by the teachers as part of a flipped classroom, and whether these videos contribute to a good learning environment. The sample consists of 21 engineering students, 17 nursing students and 17 pre-engineering students. Overall, all three student groups are satisfied with the quality of the videos. The nursing students watched videos more before the learning sessions than the other two groups. All students think videos produced with simple tools are technically satisfactory and make it easier for the students to understand the material, which leads to increased learning outcomes. They express that videos are more motivating, and that they learn more from watching a video than reading course material. Nursing students expressed a higher degree of agreement with replacing traditional lectures in other subjects with videos. All student groups think the learning environment has been good.The results indicate a connection between the learning environment being good and the videos working satisfactorily.
THE EDUCATIONAL AND THERAPEUTIC BENEFITS OF “CONTENT-FOCUSED ACCESSIBLE E-LEARNING MATERIAL” FOR VISUALLY IMPAIRED UNIVERSITY STUDENTS
Authors:   Aichi University of Technology, Japan, Ota Chikako
Published: August 2021

The idea of “educational therapy” is quite different in Japan compared to foreign countries, especially in the US, where educational therapy is quite advanced. Therefore, this study determines the educational therapeutic benefits of the author’s “Content-Focused Accessible E-Learning Material” for English self-learning, based on the concept developed in the US, particularly focusing on visually impaired students. These students experience various difficulties in higher education, such as 1) the absence of learning materials in braille, 2) commercial unavailability of magnification-capable learning materials and digital materials, and 3) lack of text-to-speech function in many learning materials. To study whether the material had any therapeutic benefits for these students, the author obtained feedback from 33 students. The feedback was based on the following questions: (1) technical aspects: Did the material reduce/rid the load/concern they felt; and (2) mental aspects: Did the material increase the willingness/autonomy or decrease anxieties and did they feel accomplished or motivated to improve their longitudinal English self-study? The findings show that the material was beneficial to them in five ways. The goal of this study was accomplished to a considerable degree; the use of this material reduced students’ mental burden in learning based on both qualitative and quantitative feedback from visually impaired students.
SCHOOL PRINCIPAL LEADERSHIP IN REMOTE SOUTH AFRICA: A LEADERSHIP AND MANAGEMENT CHALLENGE
Authors:   North-West University, South Africa, Van Jaarsveld Leentjie
Published: August 2021

To understand the circumstances under which principals in remote areas exercise their leadership and management, an investigation was conducted in the Northern Cape province, South Africa. This province is characterised by small towns with few residents. The infrastructure is not up to par, and in some cases, the socio-economic conditions are extremely poor. Unemployment is a big problem in the villages. The uniqueness of this study lies in the fact that after 1994, with the abolition of apartheid, the farmers withdrew their children from the schools and no longer supported the schools as before. As a result, the principals experienced many more challenges. The study followed a qualitative, phenomenological design from the interpretivist paradigm. The sample consisted of ten principals. Semi-structured interviews were conductedwith the principals. The inductive data analysis process was used. The required ethical clearance was obtained from the Research Ethics Committee of the North-West University and the Department of Education of the province. The results reveal that principals in remote areas, in the absence of technology, infrastructure, and support bases, have to use their skills creatively, and they need the support of the community, teachers, school management, and governing body.

This paper investigates the importance of transparency of internationalization and various obstacles and barriers that influence international short student mobility within the European Higher Education Area (EHEA) in particular in the Netherlands and in Russia. Having in mind that due to privacy regulations and availability of data regarding international short student mobility, this article is using a framework based on literature review. The authors analyze patterns in international short student mobility, both between countries andover time, notonly by using various literature analyses but as well as interviews and panel discussions atHAN University of Applied Sciences, the Netherlands and Plekhanov Russian University of Economics, Russia, to give this research an qualitative dimensionand underline how internationalization and what various factors are relevant to international short student mobility. This article presents an important contribution to this growing field of literatureby doing a comparative analysis about the factors which positively improve the international short students mobility. The three folded impact ofthis paper is obvious for the stakeholders involved: students, institutions and policy makers are responsible for the smooth cooperation and coordination for a better international mobility.
