Covid-19 is an unprecedented crisis that has affected almost all industry players including education. It has transformed our way of life and introduced a new normal to how things are done. As an effort to contain the outbreak of pandemic Covid-19, universities have shifted to online learning. In line with this, Universiti Teknologi MARA (UiTM) has decided to execute open and distance learning (ODL) for the current semester until 31 December 2020. ODL introduces a different learning environment as compared to the traditional classroom that requires students to be self-reliant in learning new things. Hence, the purpose of the study is to explore students’ experiences in the process of knowledge transfer through ODL specifically for accounting subjects. A questionnaire was distributed to students who were taking the subject of Introduction to Financial Accounting and Introduction to Cost Accounting in UiTM Pahang Kampus Raub and a total of 206 responses were received. The study found over half of the students enjoy learning through ODL but only one-third were looking forward to having ODL for the next semester. Poor internet connection is the main reason found in the study that makes ODL not preferred by the students. At the same time, few features were highlighted by the students about ODL such as the advantage of pre-recorded video to catch up the new material and flexibility for them to learn at their own pace.

Abstract Our experience with technology is a bitter-sweet one. We relish its presence in our lives, but we dread the effect it may have on our manners, attitudes and social interactions. We open the gates of our schools to all types of technological tools, yet we fear it may badly impact our students’ performance. This article investigates the ways through which classroom technology such as iPad, Internet connection, laptops and social media, impacts negatively on education. Relevant research has proven that technology could change education negatively through four paths: deteriorating students’ competences of reading and writing, dehumanizing educational environments, distorting social interactions between teachers and students and isolating individuals when using technology.

Background: With the availability of multiple options in wireless network simultaneously, Always Best Connected (ABC) requires dynamic selection of the best network and access technologies. Objective: In this paper, a novel dynamic access network selection algorithm based on the real time is proposed. The available bandwidth (ABW) of each network is required to be estimated to solve the network selection problem. Method: Proposed algorithm estimates available bandwidth by taking averages, peaks, low points and bootstrap approximation for network selection. It monitors real-time internet connection and resolves the selection issue in internet connection. The proposed algorithm is capable of adapting to prevailing network conditions in heterogeneous environment of 2G, 3G and WLAN networks without user intervention. It is implemented in temporal and spatial domains to check its robustness. Estimation error, overhead, estimation time with the varying size of traffic and reliability are used as the performance metrics. Results: Through numerical results, it is shown that the proposed algorithm’s ABW estimation based on bootstrap approximation gives improved performance in terms of estimation error (less than 20%), overhead (varies from 0.03% to 83%) and reliability (approx. 99%) with respect to existing techniques. Conclusion: Our proposed methodology of network selection criterion estimates the available bandwidth by taking averages, peaks, and low points and bootstrap approximation method (standard deviation) for the selection of network in the wireless heterogeneous environment. It monitors real-time internet connection and resolves internet connections selection issue. All the real-time usage and test results demonstrate the productivity and adequacy of available bandwidth estimation with bootstrap approximation as a practical solution for consistent correspondence among heterogeneous wireless networks by precise network selection for multimedia services.

AbstractEmergency planners and first responders often access web-based information resources during disasters; however, these tools require an active Internet connection, which may be unavailable during a disaster. The National Library of Medicine (NLM) provides several free non-web-based disaster response tools. This study assessed intention to use web-based and non-web-based informational and response tools during disasters among emergency responders and librarians. Educational workshops were held in four Missouri cities in spring, 2016. The NLM tools were presented and attendees practiced using the tools during disaster scenarios. Pre- and post-intervention data about NLM tool awareness and intention to use these tools versus other web-based resources was collected. McNemar tests assessed a pre/post change in intention to use each resource. Four workshops were held, with a total of 74 attendees. Intention to use the NLM tools was low prior to the workshops (range: 20.3–39.2%), but increased significantly immediately afterwards (p < .001 for all pre/post comparisons). The workshops resulted in increased NLM tool awareness and increased intention to use the tools during future disasters. This provides evidence of attendees’ perceptions of the usefulness of the non-web-based NLM tools in place of other web-based tools in situations without Internet access.

The COVID-19 (SARS-CoV-2) pandemic required changes to be made, especially in formal education processes. In order for the students to stay safe and healthy, many educational institutions switched to the distance learning method for the rest of the semester and continued their education without any intermission. Due to this switch, there has been a rise in the usage of learning management systems, and as a result, students started to encounter technical problems, especially during the exam periods, or they simply wanted to obtain more information about academic or administrative issues. This study used frequency and percentage analysis methods and examined the support request tickets opened up by students during distance education. Resolving the encountered problems quickly and effectively is very important in order to protect the motivation of the learners and ensure their successes. It was seen in the study that the majority of the problems reported by the students were related to internet connection or to the problems occurred during exams. This study aimed to share experiences with the researchers and technical and administrative staff working in this field and to contribute to the current distance learning literature.

Abstract Background Telesonography systems have been developed to overcome barriers to accessing diagnostic ultrasound for patients in rural and remote communities. However, most previous telesonography systems have been designed for performing only abdominal and obstetrical exams. In this paper, we describe the development and assessment of a musculoskeletal (MSK) telesonography system. Methods We developed a 4-degrees-of-freedom (DOF) robot to manipulate an ultrasound probe. The robot was remotely controlled by a radiologist operating a joystick at the master site. The telesonography system was used to scan participants’ forearms, and all participants were conventionally scanned for comparison. Participants and radiologists were surveyed regarding their experience. Images from both scanning methods were independently assessed by an MSK radiologist. Results All ten ultrasound exams were successfully performed using our developed MSK telesonography system, with no significant delay in movement. The duration (mean ± standard deviation) of telerobotic and conventional exams was 4.6 ± 0.9 and 1.4 ± 0.5 min, respectively (p = 0.039). An MSK radiologist rated quality of real-time ultrasound images transmitted over an internet connection as “very good” for all telesonography exams, and participants rated communication with the radiologist as “very good” or “good” for all exams. Visualisation of anatomic structures was similar between telerobotic and conventional methods, with no statistically significant differences. Conclusions The MSK telesonography system developed in this study is feasible for performing soft tissue ultrasound exams. The advancement of this system may allow MSK ultrasound exams to be performed over long distances, increasing access to ultrasound for patients in rural and remote communities.
