Aspect Level Sentiment Analysis on Zoom Cloud Meetings App Review Using LDA

During the Covid-19 pandemic, almost all community activities are conducted from home. Therefore, video conference technology is needed for people to carry out their normal activities from home. One of the video conference applications is ZOOM Cloud Meetings. Applications certainly have been reviewed given by their users as a reference for new users and companies of the application to know the application’s performance. However, in reviews, some constraints are the number of reviews as well as irregular. Therefore, a solution is needed with sentiment analysis that aims to classify the reviews of the application to be organized by categorizing positive or negative sentiment. In this study, aspect-based sentiment analysis was conducted on ZOOM Cloud Meetings app reviews from Google Play Store. The analysis’s result of the review data obtained three aspects, namely aspects of usability, system, and appearance. The modeling topic used is the Latent Dirichlet Allocation (LDA) method and classification using the Support Vector Machine (SVM). This research resulted in the best performance with the best parameters resulting in the performance accuracy of usability aspect is 88.83%, system aspect with 91.2%, appearance aspect with 94.78%, and performance accuracy of all aspects 91.61%.

Klasifikasi Ulasan Pengguna Zoom Cloud Meetings Menggunakan Metode Information Gain dan Naïve Bayes Classifier

During the Covid-19 pandemic, ZOOM Cloud Meetings video conference application was felt to be of benefit. This is due to limited direct physical contact and all activities are carried out virtually from home. So that during the pandemic the ZOOM Cloud Meetings application was widely downloaded by various groups of people, and reaped various responses from users who complained on the Google Play Store. Complaints from user reviews can contain valuable information for application development. To obtain this information, user reviews of applications are classified based on the ISO 9126 category. ISO 9126 is one of the standards for evaluating software based on user satisfaction. The ISO standards used are functionality, efficiency, reliability, maintainability, portability, and usability. This study uses the CRISP-DM research methodology and for modeling in the classification applies the Naive Bayes Classifier and Information Gain. Information Gain is used for word conversion and data transformation from categorical to numeric and to reduce data dimensions. Naive Bayes is able to predict data to enter the classification class. Testing of the model applies manual and automatic k-fold cross validation testing. The results of the classification of the model in manual testing produce the best accuracy of 79% and the k-fold cross validation test is 80.51%. The existence of this accuracy value is expected to be a reference for developing the ZOOM Cloud Meetings application.

Problems on learning thinking aloud for reading via Zoom app in emergency remote learning class

This research attempted to obtain information on the problems of learning think-aloud for reading in an emergency remote learning class utilizing Zoom video conference application as the means of communication. While think-aloud is well-known method for improving students' reading strategy usage management, there are still problems encountered during class, especially if it is learnt via Zoom video conference application. The research participants were nine D3 program students of AMIKOM Purwokerto University PSDKU Yogyakarta who took Reading IV class. Data collection procedure included literary research, observation, questionnaire, and group interview. There were seven problems discovered: (1) Students were too shy to talk, (2) Students did not have or know proper vocabulary to verbalize their thoughts. (3). Students understood the text but had nothing to say. (4) Easy text did not invoke observable understanding processes in the students’ minds. (5) Students neither understood the text nor knew what to say. (6) Time-consuming. (7) Internet disconnection. Simple solutions to those problems were also presented.

Student satisfaction on the implementation of the online undergraduate thesis examination: a PLS-SEM analysis

PurposeThe covid-19 pandemic that hit the world has caused several changes in the higher education service sector, including the implementation of the undergraduate thesis examination, where direct interaction between students and examiners is avoided and replacing it with an online bachelor thesis exam. This study aims to develop a conceptual model regarding the variables that can affect student satisfaction with the quality of the implementation of online undergraduate thesis examinations in higher education.Design/methodology/approachThe research instrument consisted of 22 survey questions distributed to 583 students taking the thesis trial examination in the even semester of 2019/2020 who came from 12 different study programs. Factor analysis and structural equation modeling (SEM) were conducted to analyze the validity of the instrument and test the hypothesis. The results of the analysis show that the 22 instrument items used have been determined by sufficient variables to check the structure of each.FindingsSEM analysis results show that the three hypothesized variables (study program service, examiner performance and quality of video conference applications) positively and significantly affect the level of student satisfaction with the online undergraduate thesis examination 0.187, 0.177 and 0.177, respectively. The total effect of these three factors is 0.737.Research limitations/implicationsThis finding is a reference for those who want to improve the quality of the online undergraduate thesis examination in higher education.Originality/valueAs the online thesis examination was implemented in higher education in Indonesia as a result of the implementation of the study and work at home policy by the Indonesian Ministry of Education, it is important to conduct research on the implementation of online thesis exams in Indonesia, especially to study the conceptual model of variables affect student satisfaction with the implementation of the online thesis exam. Because even though the implementation of online thesis exams on a large scale is new to some higher education in Indonesia.

The Potential of Podcast as Online Learning Media for Supporting Visual Impairment Students to Introduction to Education Course in Universitas Negeri Padang

Education equality has been a critical issue in higher education where the students with special needs should obtain the equal opportunities to acquire knowledge through the appropriate learning methods and media. This article discussed the analysis of the potential of Podcast as learning media for inclusive students, specifically for those with visual impairment in online educational setting. This study conducted the qualitative methods with focus group discussion to collect the data. Four blind students from Special Education Department, Faculty of Education in Universitas Negeri Padang involved through video conference application, Zoom, approximately 50 minutes. There were two aspects would be analysed, such as: the characteristic of the learners and the course, and current learning situation. For the results, it is indicated from the students that there should have been certain methods and media to increase the engagement of inclusive students to the materials provided in online learning. As the students have difficulty in visual ability, it is necessary to develop a specific learning media to help the students cope with the problems. Developing Podcast for learning is expected to be one of the strategies to help blind students understand the topic studied more easily.

Virtual Handover of Patients in the Pediatric Intensive Care Unit During the Covid-19 Crisis

ObjectiveA key measure to mitigate coronavirus disease 2019 (COVID-19) has been social distancing. Incorporating video-conferencing applications in the patient handover process between healthcare workers can enhance social distancing while maintaining handover elements. This study describes pediatric intensive care unit (PICU) physicians’ experience using an online video-conferencing application for handover during the COVID-19 pandemic.DesignQualitative content analysis.SettingPICU at a university hospital in Riyadh, Saudi Arabia.SubjectsPICU Physicians.InterventionsDue to the pandemic, the hospital’s PICU used Zoom® as a remote conferencing application instead of a face-to-face handover. Following institutional review board approval, data were collected over two weeks (1 Jul 2020 to 14 Jul 2020).MeasurementsAn online survey was conducted using open-ended questions to capture demographic data and the perceived efficacy of remote handovers. Thematic framework analysis process included open coding, creating categories, and abstraction.Main ResultsAll 37 PICU physicians who participated in the handover completed the survey. The participants comprised six attendings, nine specialists, and 22 residents. While 20 (54.1%) physicians reported attending 1–5 Zoom handovers by the time of the study, some (n. 6, 16.2%) had more than ten virtual handovers. They had variable previous teleconferencing experiences. Most physicians (78.4%) were comfortable conducting a remote handover. Most found that Situation–Background–Assessment–Recommendation handover elements were properly achieved through this remote handover process. The perceived advantages of online handover included fewer interruptions, time efficiency, and facilitation of social distancing. The perceived disadvantages were the paucity of nonverbal communication and teaching during virtual meetings.ConclusionVideo-conferencing applications for online handovers could supplement traditional face-to-face intensive care unit patient handover during outbreaks of infectious diseases. The use of video streaming and more emphasis on teaching should be encouraged to optimize the users’ experience.

Early detection of link failures through the modeling of the hardware deterioration process

Network failures can significantly degrade the network performance in several ways, ranging from experiencing unacceptable delays (e.g., in video conference applications) to leading to significant drops in sales for companies (e.g., airlines tickets purchases). In this paper, we focus on network failures caused by links that are prone to fail due to their advanced stage of lifetime. In particular, the formalization of the Hardware Deterioration Failure Mode (HDFM) for network line cards is provided to evaluate the penalty for network operators of handling HDFM failing links using classical methods based on Bidirectional Forwarding Detection and Fast Re-Route mechanisms. An algorithm, named Hardware Deterioration Detection (HDD), is proposed to detect if links are experiencing failures as well as to provide an estimation of their remaining lifetime. The performance evaluation over data generated by our provided network failure simulator shows that HDD is able to correctly classify links as failing or not failing, regardless of the type of failure considered. Moreover, overall descriptions for failure models in which HDD is able to produce high quality estimations of the remaining lifetime have been identified, with a trade-off between the hardware deterioration time dependence and the relationship between lifetime and packet loss probability.

Sociodemographic Factors and Adoption of Social Media as a Management Tool by Managers and Administrators in Selected Non-Governmental Organizations in Kigali, Rwanda

Social media use has gained prominence in the public as well as in the work environment as a way of quickly and widely sharing information and its crucial role in management has been elevated even more by the covid-19 pandemic which has severely limited human physical interaction. This study was carried out to explore the sociodemographic factors and adoption of social media as a management tool among managers and administrators in selected Non-Governmental Organizations in Kigali Rwanda. The study focused on the popular social media applications that can be of use in management namely, Facebook, Twitter, WhatsApp, video-conferencing applications, and YouTube. The study employed a descriptive cross-sectional design with an online survey questionnaire administered to a sample size of 217 respondents purposively sampled from six selected NGOs in Kigali Rwanda. Findings indicated that the overall social media adoption was quite high with WhatsApp being the most popular app. Several respondents’ characteristics such as age, education and job level showed statistically significant association with adoption of particular social media applications. Findings, however, revealed no structured approach to social media use in most of the surveyed NGOs. The study concluded that the overall adoption rate of social media was quite high but with a huge disparity in usage rates of specific social media applications and that certain sociodemographic factors such as education level and training appeared as strong predictors of social media adoption. This study recommended therefore, that NGOs should determine the applications that support their business model and provide comprehensive policies and support to encourage the employees to adopt the chosen social media applications in their managerial functions. The policy makers should also promote the modifiable sociodemographic factors that influence social media adoption such as education level and training.

Tele-forensic interviewing can be a reasonable alternative to face-to-face interviewing of child witnesses.

Tele-forensic interviews have the potential to aid investigations when children live far from interviewers, there is a risk of disease transmission, or when expertise is not locally available. However, it is unknown whether tele-forensic interviewing is an effective alternative to face-to-face interviewing, particularly for children most prone to suggestibility and lapses of attention. Previous studies suggested that school-age children would provide similar amounts of information across interview modes but provided no basis for predicting how misinformation impacts accuracy across modes or how 4- and 5-year-olds would react to tele-forensic interviewing. Children (4-8 years, N = 261, Mage = 6.42 years, 48% female) interacted with male assistants who violated a no-touching rule, parents read children a book containing misinformation about that event, and female assistants conducted interviews (usually 2 weeks after the event) face-to-face or via a video conference application. The children were more talkative during a practice narrative phase when interviewed face-to-face rather than on screen (incidence rate ratio [IRR] = 1.26, 95% CI [1.06, 1.51]), and 4-, 5-, and 6-year-olds said more in response to open-ended prompts when interviewed face-to-face (IRR = 1.50, 95% CI [1.08, 2.09]). Children younger than 7 years also disclosed the face touch and noncompleted handshake in response to earlier and less directive prompts when interviewed face-to-face, rs(53) = .28, p = .037, and rs(48) = .33, p = .021, respectively. Children 8 years and older, however, disclosed the face touch more readily when they spoke on screen, rs(28) = -.38, p = .036, and older 7-year-olds and 8-year-olds disclosed the noncompleted handshake more readily on screen, rs(30) = -.36, p = .042. Across interview modes, children reported comparable numbers of touch events, however, and were equally accurate on challenging source-monitoring and detail questions. Tele-forensic interviewing can be a reasonable alternative to face-to-face interviewing. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Therapeutic Alliance in COVID-19 Era Remote Psychotherapy Delivered to Physically Ill Patients With Disturbed Body Image.

The COVID-19 pandemic outbreak has led to a general reorganization of health services and an increase in outpatient telemedicine in mental healthcare for physically ill people. Current literature highlights facilitators and obstacles concerning the use of new technologies in psychotherapy, an underrated topic of research in the context of supportive expressive psychotherapy. More insight is needed to explore the characteristics of video in therapeutic alliance for treatment of specific mental disorders experienced in psychosomatics, particularly with people suffering from a disturbed body- and self-image. Using two clinical vignettes, it is the authors’ intention to enrich the critical debate on current knowledge in psychosomatic remote psychotherapy, with special focus on mentalization deficits and their impact on therapeutic alliance in the consultation-liaison psychiatry setting. In particular, we will question the interpersonal processes at stake related to mirroring and the disruption caused by the use of videoconference applications. We will also reflect upon the relationship between the therapeutic alliance and the medical team, and that between patient and psychotherapist. The aim is to improve psychotherapeutic alliance maintained during the pandemic for specific mental disorders and to inform about possible clinical factors that could be the subject of future empirical studies or professional guidelines.

Conventions

Artists told me it was the end of hope. Before COVID-19, working as an artist was already challenging. But suddenly it was, “there is no hope”. I will never forget it.’ Juliana Akoryo, the Commissioner for Culture and Family Affairs in Uganda, is calling from her office in Kampala via Zoom, the video conference application. She is thinking back to the beginning of 2020, when the threat of COVID-19 began to be felt across the world. ‘I immediately knew the arts were going to be in trouble. Cultural events in Uganda take place in large spaces and bring huge crowds of people.’

Establishing Performance Indicators of Telemedicine-Based "On-Consultation Training" of Primary Care Doctors: An Innovation to Integrate Psychiatry at Primary Care.

Background:A “functional treatment gap” exists in primary care of India despite the higher prevalence of psychiatric disorders at primary care. Traditional classroom training for primary care doctors (PCDs) fails to translate into adequate clinical skills to provide basic psychiatric treatment. An innovative telepsychiatric on-consultation training (Tele-OCT) is designed exclusively for practicing PCDs where a telepsychiatrist trains PCDs in live video streaming of their own real-time general consultations of primary health centres. The aim of this study is to establish performance indicators of Tele-OCT for its effective implementation.Methodology:The data collected using a file review method from a naturalistic design of the implementation of Tele-OCT for 73 PCDs from August-2016 to October-2018 across Mandya district, Karnataka, India.Results:Flexibility in the scheduling of Tele-OCT sessions is key to success. Personal smartphones of PCDs with available videoconference applications are the popular choice. Four consecutive Tele-OCT sessions are planned for each PCD with a gap of 2–4 weeks over two months. The first three sessions are considered the “optimum Tele-OCT training package” for each PCD, followed by the fourth one as a ‘Tele-OCT impact evaluation session' in a live, real-time general consultation. Each Tele-OCT is conducted in an average ten general patients in about two hours per session, totalling about 30 patients in 6 hours of Tele-OCT training package per PCD. Patient's profiles especially common mental disorders are reflective of a true picture of Indian primary care.Conclusions:Performance indicators of Tele-OCT for future implementation are established. Tele-OCT appears to be a path-breaking training model for PCDs to integrate psychiatric care in their general practice.

Students Perception of The Full Online Learning Quality During The Corona Pandemic

Due to the Pandemic of Covid-19, teachers or lecturers must hold a full online teaching-learning process, so they should integrate technology into the teaching learning activities. To engage students in full online learning, Google Classroom, Edmodo, Kahoot, and Quizziz are some online learning platforms that are widely used by English teachers in teaching and learning. There are some video conference applications for doing video calls in the teaching-learning process, they are Zoom and Google Meet. This study focuses on students’ perceptions of the full online learning quality during the corona pandemic. The research involved 50 participants consist of students of the English Education program in the second semester of IAIN Purwokerto. The data were collected through questionnaires, interviews, and observation and were analyzed using the qualitative methods approach. The results of the study indicated that the majority of participants considered did not enjoy the full online learning in English teaching and learning is not effective and efficient in terms of time and phone credit. One of the reasons is the slow-speed internet is one of the difficulties in operating those applications. So, they feel they could not get maximum knowledge and information from their lecturers in full online teaching-learning activities.

Strengthening the ACS experience for our international members

When this year began, I was looking forward to many aspects and activities of my final year as chair of the Committee on International Activities (IAC): going to committee meetings at American Chemical Society national meetings, interacting with sister society leadership, and working with my stellar fellow IAC members to enact activities around a new strategic plan. However, as with many people’s plans for 2020, my initial vision for my last year as chair has turned out differently than I had anticipated. While there have been some growing pains with the shift to conducting ACS business primarily online, there have also been positive outcomes. We are using videoconference applications more often than phone calls, adding a personal touch to our communications. Our efforts to coordinate schedules for virtual meetings have made us more aware of time-zone differences with our colleagues around the world. All this helps make our international collaborations

The Virtual Shoulder and Knee Physical Examination.

The COVID-19 crisis has forced a sudden and dramatic shift in the way that clinicians interact with their patients, from outpatient encounters to telehealth visits utilizing a variety of internet-based videoconferencing applications. Although many aspects of pre–COVID-19 outpatient sports medicine care will ultimately resume, it is likely that telehealth will persist because of its practicality and because of patient demand for access to efficient and convenient health care. Physical examination is widely considered a critical obstacle to a thorough evaluation of sports medicine patients during telehealth visits. However, a closer reflection suggests that a majority of the examination maneuvers are possible virtually with limited, if any, modifications. Thus, we provide a comprehensive shoulder and knee physical examination for sports medicine telehealth visits, including (1) verbal instructions in layman’s terms that can be provided to the patient before or read verbatim during the visit, (2) multimedia options (narrated videos and annotated presentations) of the shoulder and knee examination that can be provided to patients via screen-share options, and (3) a corresponding checklist to aid in documentation.

Crisis Management and Communication Experience in Education during the COVID – 19 Pandemic in Indonesia

The focus of this research is crisis management in the education sector during the COVID-19 pandemic. This was done following an atmosphere of crisis in the field of education that encouraged the Indonesian government to issue policies in the form of the Study from Home (SfH) crisis programme. The object being analysed is related to the application of crisis management and the communication experience of students during the programme. The purpose of this study is to describe the opinions of students during the crisis programme. The study was conducted in the city of Bandung by involving lecturers and students. The methodology used is a qualitative approach to phenomenological studies. Data collection was conducted through online interviews and literature studies. The study found that the government established SfH as an emergency learning programme during the COVID-19 pandemic. The implementation of SfH was through online learning using various chat and video conference applications. There were two weaknesses of online learning namely technical and communication weaknesses. Technical weakness is influenced by geographical factors, internet networks, and internet costs. While communication weaknesses include slow adaptation, learning media are not optimal, and an interactive atmosphere has not been developed, and there is no atmosphere of empathy. This situation results in lecturers not being able to manage the learning effectively. Studying online during SfH should be able to build collaboration classes to be able to foster motivation and interest in student learning. Collaboration classes are realised when lecturers and students try to improve communication competencies. Keywords : COVID-19, crisis management, communication experience, online learning, study from home.

International Trends of Remote Teaching Ordered in Light of the Coronavirus (COVID-19) and its Most Popular Video Conferencing Applications that Implement Communication

The global coronavirus pandemic that emerged at the end of 2019 and will reach its peak in 2020 has affected education systems worldwide and led to widespread, complete closure of schools, universities, and colleges. UNESCO estimates that a total of nearly 1.6 billion students worldwide have been affected by the closures of educational institutions. The indicator was the highest in the period from April 1 to April 5, when exactly 1,598,099,008 students were affected by the measures. This accounted for 91.3% of the world’s total learning community, with a total of 193 countries providing full nationwide remote teaching. In response to school clo-sures, UNESCO has proposed distance learning programs as well as open educational applications and platforms that have ena-bled schools and teachers to reach their students remotely and make online education easier (UNESCO, 2020). In addition to reviewing the recent literature and monitoring lockdown measures, the study also suggests a number of specific solutions.
