Abstract PRISM 2.0 was designed to run on Android tablets and made use of both customized apps that relied on Google’s browser and e-mail functionality as well as commercial apps, such as Microsoft’s Skype for videoconferencing. We also made use of functionality provided by our partner AT&T, such as their sim cards to provide cell-based internet connectivity to participants who did not have access to Wi-Fi internet services to their home (cable, DSL), as well as tablet management software to deploy updates. The Miami site provided central management and tablet deployment and redeployment services and support as well as coordinating locally provided tech support at the three sites. We discuss some of the technical challenges associated with these arrangements. We focus on how changes to the operating system broke some of our apps necessitating substitution of other apps and provision of new training, and how Covid-19 affected technical support.

The VoIP communication system at OMNI Hospital Alam Sutera uses the Elastix 2.5 server with the Centos 5.11 operating system. Elastix 2.5 by the developer has been declared End of Life. The server security system is a serious concern considering that VoIP servers can be accessed from the internet. Iptables and fail2ban applications are applications that are used to limit and counteract those who try to attack the VoIP server. One application that can be used as an open source VoIP server is the Issabel Application version 4.0. The migration process from Elastix 2.5 application to Issabel 4.0 by backing up all configurations in the Elastix 2.5 application through a web browser including the configuration of endpoints, fax, e-mail, asterisk. After the backup file is downloaded then upload the backup file to the Issabel 4.0 application then run the migration process. Adding a backup path as a failover connection is needed because the VoIP communication protocol between the OMNI Hospitals Group still uses one path so that when there is a problem in the connection path, the communication protocol will stop. The tunnel EoIP is a protocol used as a backup path between the OMNI Hospitals Group site.

Paper Submission

The use of electronic files made universally readable in Adobe Acrobat will eventually replace paper submission in nearly every avenue used by scientists, whether files go to grants agencies, to reviewers, to colleagues via e-mail, or to publishers. It's for the obvious reason of reducing paper and the costs of mailing, but also because fonts often misbehave when going across operating system platforms, and because seemingly everyone has the Acrobat Reader, A better understanding of Adobe Acrobat can go a long way toward reducing the frustration that can easily arise from using this program inappropriately and ending up with poor image resolution.

This study aims to describe the impact of the lockdown amid the COVID-19 outbreak on university students in West Java. An online survey was conducted from July 1 to July 8 2020. The structural questionnaire instrument used was the 'Google form' sent to students via WhatsApp and E-mail. A total of 231 students provided complete information regarding the survey. Simple percentage distribution is used to assess the learning status of study participants. During the lockdown period, around 70% of students were involved in e-learning. Most of the students use android phones to follow e-learning. Students have faced various problems related to anxiety depression, poor internet connectivity, and a low learning environment. Students from remote and marginalized areas, especially face significant challenges to learning during this pandemic. This study suggests targeted interventions to create positive spaces for learning among students as part of society. Strategies are urgently needed to build a sound education system during the pandemic to not interfere with student skills and productivity.

Descriptive Survey

The study seeks to ascertain the levels of awareness and usage of reference management software (RMS) among researchers of the Council for Scientific and Industrial Research (CSIR), Ghana. The purpose and benefits as well as challenges associated with the use of these tools were also discussed. Descriptive survey methodology was employed for this study. A web-based questionnaire consisting of both multiple-choice and open-ended questions was used to collect data from 110 scientists in 13 research institutes of the CSIR, Ghana. Results show that overwhelming majority of scientists (80%) are aware and know about RMS. However, the adoption and usage of these tools are low. The percentage of non-usage was higher among the older scientists (22% for over 51 years) as against the younger researchers (9% for 31 to 40 years). Overall, 33.6% do not use RMS at all, and scientists occasionally used RMS. Mendeley was the most popularly used software among respondents. Results also show that most of the respondents got to know about RMS through training workshops and seminars. Most of the respondents had not received any training and for those who had attended a training workshop or seminar, majority of them noted that it was very easy to use. The main purpose of using these tools was for research work and literature review. Major benefits of using RMS packages are automatic generation of references list, electronic creation of bibliographies and changing of referencing style by a click of a button. Challenges associated with the use of these tools were slow internet connection, lack of training, and technical support. The study recommended that CSIR should make the effort to acquire these tools. Scientists should also be given the necessary training and technical support in order to effectively use these softwares.
