Full textAbstract:
Is our mental health at risk due to spending a significant amount of time online due to the COVID-19 pandemic? In the new era that we are living in, where we live a life that coexists with the virus, we are participating in video conferences held online rather than on-site in order to slow the spread of the virus. Video conferencing has become our necessity since March 2020, and is becoming a new standard, especially in the MICE industry. Recently, however, people who have excessively used video conference platforms are complaining of video conference fatigue, which is a new negative emotion such as stress, anxiety, and worry as well as general work fatigue. Therefore, this study focused on the mechanism of video conferencing in MICE, which is rapidly digitally converted by the virus, and the digital psychological factors of the participants. This study derived the quality attributes of video conferencing in MICE and empirically analyzed the relationship with digital psychological factors of the video conference participants, such as video conference fatigue, social presence, and flow. One hundred and thirty-eight valid questionnaires collected from participants of several international academic conferences held in EXCO, Daegu, Korea, from 23 to 28 May 2021, were analyzed. The main results are as follows. First, unlike general video conference fatigue, MICE video conference fatigue was not found to be related to the preceding and following variables. This is due to the characteristics of the MICE video conference and the expertise of the participants. Second, social presence was identified as an important variable in MICE video conferencing. Although media-mediated, the feeling of being present with the presenter and participants was found to affect the participants’ flow in the video conference. Third, in this study, the fun factor was identified as the most important video conference quality that can enhance the social presence of the video conference participants of MICEs.

Full textAbstract:
Virtual conferences are environment-friendly alternatives to physical conferences. COVID-19 pandemic has increased the use of virtual conferences. However, they are not without their share of impact on the environment. We assessed the carbon emissions (CE) of a three day national public health conference with 1474 attendees held in virtual mode and the potential CE saved compared to the physical mode. The CE of the virtual conference were estimated to be 6.44 Metric Tonne (MT) carbon dioxide (CO2) Equivalent (Eq). Potential CE that would have resulted from the physical mode of the conference were 355.85 MT CO2 Eq which is 55 times higher than the virtual mode. The live video streaming of the proceedings was the highest contributor to the virtual conference’s overall CE (81.5%). A digitally sober conference would have emitted 1.27 MT CO2 Eq, translating to a CE reduction of 80.3% from the estimated virtual conference emission. Academic conferences should strive to become carbon neutral by adopting the virtual mode of conferencing, and within that, digital sobriety should be the policy of action. Policies to motivate the adoption of virtual conferencing and digital sobriety need to be undertaken at the organizational and individual levels.

Electronic activities are realized on the Internet due to the growth of the Internet. As conference organization is getting more popular, we proposed an electronic virtual conference system (EVCS) to handle all activities of real-world conferences. The EVCS includes a virtual conference management system (VCMS) and a mobile conferencing system (MCS). Video conferencing is a trend of future communications. With the improvement of broadband network technologies, video conferencing becomes possible in the global society. It is feasible to use video conferencing technologies to organize future international conferences. As such, transportation and accommodation costs are saved. This paper proposed a total solution toward virtual conferencing. We use a mobile server/storage pre-broadcasting technique, as well as a communication network optimization algorithm, which is based on a graph computation mechanism. The system also relies on a network bandwidth reservation facility as well as a multicasting control function. With the assistance of the virtual conference management system, the system is able to support virtual conferencing in the future academic society.

Abstract The motivation for the project was the necessity of finding solutions to situations characterized by difficulty in communication, such as trading between different countries, immigrants unable to speak the language, or between hearing and deaf people who use sign language. These and other cases can be solved thanks to interpreting services. Yet because of educational commitments of professionals, organizational time, budget, and locations, it is not always possible to avail of an on-site interpreter. In this context, technology offers a solution through remote interpretation. The present draws inspiration from the research project “VEASYT Live! for conference: linguistic and technological solutions for the supply of video remote interpreting services in conference settings”. The work was financed by the European Social Fund and took place between 2016 and 2017 in the Linguistic and Cultural Compared Studies Department of Ca’ Foscari University of Venice in partnership with VEASYT srl, a company that developed a video remote interpreting (VRI) service in both vocal languages and Italian Sign Language. The aim of the research is to develop VRI for conference situations such as seminars, conferences and academic lectures.

During the covid-19 pandemic, most lecturers in higher education conduct the learning process with video conference. However, it seems that the use of video conferences in learning is believed to still be considered no more effective than face-to-face methods directly. Various perceptions related to the use of video conferences have sprung up from various circles. This research aims to find out the perception of students to the use of video conferences in the learning process in the pandemic period. The sample consisted of 49 students at one of the universities in Mataram City. The method used in this study is descriptive research methods. The data was retrieved using questionnaires and interviews. Based on the results of the data analysis showed that, as many as 86.39% of students have a positive perception of the use of video conferences in the learning process during the pandemic. The average student assumes that using video conferences can facilitate the learning process, can motivate students in learning, and more effective in communicating with lecturers when compared to using platforms that can only send messages in the form of text.

Video Conference merupakan salah satu teknologi yang banyak digunakan untuk pembelajaran pada masa pandemi Covid-19. UIN Maulana Malik Ibrahim Malang sebagai salah satu perguruan tinggi yang menerapkan pembelajaran daring (dalam jaringan) memiliki platform video conference sendiri yang terhubung dengan sistem pembelajaran elektronik (e-learning). Namun tidak semua mahasiswa dapat mengakses koneksi internet yang lancar. Hal ini menyebabkan penurunan kualitas video conference sehingga mengganggu proses pembelajaran. Penelitian ini berupaya menemukan cara untuk memperbaiki kualitas video conference pada koneksi internet yang terbatas. Teknik yang digunakan untuk memperbaiki kualitas video conference adalah dengan memprioritaskan paket data video conference dibandingkan paket data yang lain pada antrian router. Dengan demikian akan dapat meminimalisir delay & jitter pada video conference. Hasil dari penelitian menunjukkan bahwa dengan memanipulasi antrian paket data pada jaringan komputer, dapat meningkatkan kualitas video conference pada bandwidth yang terbatas dari parameter delay dan jitter antara 20% - 30%. Sedangkan untuk packet loss menunjukkan 0% namun retransmission packet cukup banyak pada skenario tanpa prioritas paket terutama pada bandwidth < 3Mbps. Hasil dari penelitian ini menunjukkan bahwa manipulasi prioritas paket data berdampak pada berkurangnya lag / informasi yang hilang ketika proses video conference berlangsung terutama pada bandwidth < 3Mbps.

Full textAbstract:
The COVID-19 epidemic has made online video conferencing extremely popular throughout the world, with many schools, companies and government sectors using video conferencing applications (e.g., Zoom, Google Meet) in a daily basis. These applications also provide local or cloud recording services, which allow the replay or sharing of video conference recordings (VCRs) in a later time. Such convenience, however, can easily cause infringement of privacy as meeting participants’ personally identifiable information (e.g., face, name, voice) may be exposed to the public without their awareness or consent. While privacy regulation and training can help relieve the situation, efficient and effective tools are also highly desired to protect the privacysensitive users in the VCRs before their public releases. In this work, we propose the first Privacy-Preserving Publishing system (ZoomP3 ) that automatically processes video and audio information in VCRs for privacy protection. Besides leveraging and integrating multiple state-of-the-art computer vision and audio processing tools seamlessly into our system, a number of optimization algorithms are proposed to improve the scalability of the system, enabling it to protect the privacy of long video conferences. We have conducted various tests with short and long videos, and the results (with online demos) verified that ZoomP3 system is suitable for largescale use. It may be applied as an online service, e.g., by Zoom, or by large organizations such as universities, research institutes and government sectors.

2021 2ND International Conference on Artificial Intelligence, Computer Networks and Communications were successfully held online from 28th to 29th October 2021, Hefei, China. The conference was jointly organized and sponsored by Shaanxi Juxing Exhibition Co., Ltd and Juneng Electronic Technology Co., Ltd. Called by Dr. Tao Wang from School of Data Science and Computer, Sun Yat-Sen University and researcher Shuanghua Yang from the Engineering College, Southern University of Science and Technology, the conference invited scholars and experts in the fields of artificial intelligence, computer networks and communications from various universities to participate in the review and guidance of this conference. The conference focuses on the latest research fields such as “artificial intelligence”, “computer networks” and “Communications”, and aims to provide an international cooperation and exchange platform for experts, scholars and business managers in the fields of artificial intelligence, computer networks and communications application to share their research achievements, discuss the key challenges and research directions of the development of this field, and jointly promote the industrialization cooperation and continuous innovation of international academic achievements. This collection of Proceedings compiles oral and paper presentations submitted by the authors and scrutinized by the Special Committee. The conference was scheduled to be held on October 28-29, 2021 at The Westin Hefei Wanda Hotel, Hefei, Anhui, China. In view of travel restrictions and indoor activities related to COVID-19, we were forced to move the conference online. Attendees were notified one month in advance that the on-site conference was changed to an online conference, and the time and order of the conference were determined. The online conference was held on the video conferencing software Tencent Meeting. The video conference was held on the original date, but due to the large number of attendees, we extended the Meeting for 2 days. Due to the wide coverage of this conference and the large number of attendees, we divided the conference into main venue and sub-venue. The opening ceremony was held in the main venue and a speech was delivered by the invited speaker. After the main venue, we divided the invited 53 authors into 2 groups. Each author spoke for about 10-15 minutes on detailed material in the slides, with the same amount of time set aside for questions and discussion. The format of questioning and discussion was that after each author’s introduction, the conference chairman and committee members asked and answered questions. At least one attendee could ask questions that will be answered by the speaker. This conference has brought together many excellent works and the latest ideas and concepts. New ideas have been provided in the fields of information technology and mechanical engineering applications. For this, we have set up three awards, which were won by six authors. Due to the large number of attendees and the instability of the video conference software, we edited and retained part of the conference speech pictures and videos after the video conference. We put some screenshots of the conference on the official website for display. Although most attendees expressed regret that we had not been able to have the informal face-to-face discussions that usually take place between conferences, the virtual conferences had been surprisingly successful. The organizing and editorial committee of the AICNC 2021 hopes you enjoy the reading of this volume of the JPCS. Besides, we wish to thank all authors and participants for providing their valuable contributions for this proceeding as well as the reviewers for their constructive recommendations and criticism aiding to improve the presented articles. Likewise, we are confident that this issue will serve as a reference for experts, scholars and enterprise managers in the fields of the artificial intelligence, computer networks and communications.

To give much greater size sample, this study took two sample classes with the overall fifty-six students participated in this study by using cluster sampling technique. This study employed a qualitative research design focusing on the survey study method. A self-administration of twenty questionnaires provided to identify the distinctions perceptions between male and female students thought. A depth information appear to be as important to gain more in-depth information and continuous responses to explore the advantages and its disadvantages of video conferencing that have been undertaken by interviewing the students. The findings revealed that despite some limitation, the teaching and learning process with video conferencing was successful, then male students appear more favorably and react positively compared to female students. By having more positive responses, video conferencing proven to enhance teachers’ productivities. More significantly, students argue on its advantages and disadvantages of video conferencing that was undertaken by interview. The advantages of video conference such as video conference could connect between teachers and students wherever they are, video conference alow them to access lessons with teachers separately, video conference motivated, video conference enhances teachers’ role, responsibility, creativity, and students’ insights and learning experiences using new learning systems. Besides, video conference also has weaknesses or disadvantages when it is applied such as interactions limits, unstable internet connections, unclear sounds, video delay, and background noises. This can be noted that today learning and teaching process can benefit from using video conference as a distance learning media that teachers can used to improve their productivity, as well as substitution for teachers’ absences in the classroom, so that learning can be done, and teacher productivity maintained wherever they are. Keywords: Male and Female, Video Conference, Distance Learning Media, Teachers’ Productivities.

Jumlah penggunaan video conference di dunia semakin berkembang, dengan tingginya penggunaan video conference semakin tinggi pula aspek-aspek yang diperhatikan, diantaranya aspek kenyamanan dan keamanan. Berbicara tentang aspek kenyamanan pada video conference tidak lepas dari kompresi yang digunakan, baik kompresi audio dan video. Dewasa ini teknologi kompersi untuk video sudah sampai pada codec H.264 dan H.264-High Profile, dengan menggunakan teknologi H.264-High Profile dapat mengkonsumsi bandwidth setengah dari H.264 (tanpa enkripsi). Berbicara aspek keamanan tidak lepas dari enkripsi lalu lintas data termasuk audio dan video yang dapat di enkripsi. Untuk itulah agar dapat mendekati aspek keamanan dan kenyamanan yang seimbang perlu di analisa dan di teliti mengenai performa H.264 dan H.264-High Profile yang telah di enkripsi. Untuk meneliti tingkat aspek performa dan keamanan video conference perlu adanya teknik dan metode yang di gunakan. Dengan memanfaatkan parameter jitter , packet loss , dan PSNR kita dapat menarik kesimpulan baik atau tidaknya performa video conference. Namun untuk aspek keamanan, percakapan dua arah atau lebih harus dipastikan agar tidak dapat dilihat dan kompatibel dengan perangkat video conference yang ada. Dengan memanfaatkan teknik enkripsi pada layer 2 atau 3 hal ini memungkinkan dapat dilakukan.

Full textAbstract:
How does communication mode affect people's experience of social presence, presence, and performance, and how does it affect their actual collaboration in a virtual environment? In a first experiment, subjects communicated by text-chat, audio conference, or video conference in a desktop collaborative virtual environment (CVE). Both perceived social presence and presence were shown to be lower in the text-chat condition than in the audio- and video-conference conditions. People spent a longer time performing a decision-making task together, spoke fewer words in total, and also spoke fewer words per second in the text-chat environment. Finally, more words per second were spoken in the audio-conference than in the video-conference condition. In a second experiment, collaboration in a CVE audio- and a CVE video condition was compared to collaboration in a Web audio-conference and a Web video-conference condition. Results showed that presence was rated higher in the two video than in the two audio conditions and especially in the Web video condition. People spent more time in the video than in the audio conditions and more words per second were spoken in the Web than in the CVE conditions. In conclusion, it was found that both the communication media used and the environment in which collaboration takes place (CVE or Web) make a difference for how subjects experience interaction and for their communication behavior.

In article, which aims to apply communication network security to improve the transmission quality of an educational video conference, an adaptive resource allocation algorithm is used to optimize the transmission quality over the network. The application of the protocol to improve the transmission quality of a video conference can increase the transmission speed, reduce the bit error rate. The algorithm minimizes latency using ant colony optimization and clustering, which ultimately achieves the goal of reducing power consumption and improving security. In order to improve system performance, the problem of power distribution must be taken into account when improving the transmission quality of an educational video conference. By analyzing the adaptive resource allocation mechanism applicable to network security while improving the transmission quality of an educational video conference, conditions were created for optimizing resource allocation.

Full textAbstract:
With the rapid development of computer network application technology, various video products and video systems are changing with each passing day. The daily internal communication, training and exchange activities mainly use video conference, paperless conference, projection display, large screen splicing display and other video systems for interaction. These systems are developed and run independently and lack system linkage. In addition, due to the disunity of platforms, the system is prone to multiple devices, complex operation and low resource utilization, which increases the operation and maintenance cost. To solve the above problems, a set of multimedia video fusion system is designed to integrate various video systems to achieve unified control of video conference, paperless conference, projection display, large screen display and other systems, effectively support the use of various business scenarios, and achieve the purpose of improving efficiency and reducing costs.

Intelligibility Threshold for Cued Speech in H.264 Video Conference This paper discusses the cued speech recognition methods in videoconference. Cued speech is a specific gesture language that is used for communication between deaf people. We define the criteria for sentence intelligibility according to answers of testing subjects (deaf people). In our tests we use 30 sample videos coded by H.264 codec with various bit-rates and various speed of cued speech. Additionally, we define the criteria for consonant sign recognizability in single-handed finger alphabet (dactyl) analogically to acoustics. We use another 12 sample videos coded by H.264 codec with various bit-rates in four different video formats. To interpret the results we apply the standard scale for subjective video quality evaluation and the percentual evaluation of intelligibility as in acoustics. From the results we construct the minimum coded bit-rate recommendations for every spatial resolution.

Data transmission in the traditional video conference system is facing certain security risks currently, for which an experiment scheme for application of quantum key in the traditional video conference system is designed in this paper. As for this scheme, quantum gateway is seamlessly embedded into the traditional video conference system, based on which data transmitted through video conference system can be encrypted by the quantum key generated by such quantum gateway. Based on the reality of relatively low code generation rate of quantum key of quantum gateway, a new quantum key expansion algorithm is put forward and feasibility of such algorithm is verified by using NIST frequency test standard. Quantum keys with different error rates are used to conduct encryption and decryption of three 720p single-screen video images respectively, in addition to which Peak Signal to Noise Ratio (PSNR) of the original images and decrypted images are calculated. It can be proved through comparison between such values and theoretical calculated values that quantum key can ensure normal image quality of video. This experiment is of great significance for applying quantum key in real video conference systems and ensuring security of video data transmission.

Abstract Article is devoted to the development of free program services for video conferencing. Proposed system eliminates security flaws found in other developments. Analysis of security model development using elliptic curves and secret key transfer using Diffie–Hellman algorithm is carried out. Currently, video communication software is used everywhere. Main task of such software applications is help to people communicate with colleagues, relatives and friends at great distances. However, it is very important that their conversation remains confidential, otherwise any information said can get to third parties, and then – cost of leaking personal information can change from damage done to one person to damage done to entire states. Therefore, it is so important to use only software products that have passed certification process when communicating where information with limited access will be used. Software tool has been developed that allows creating secure video conferences with ECIES encryption algorithm on elliptic curves, which allows holding conferences without fear of being compromised. Thus, proposed application significantly increases users security, their personal data, as well as confidentiality of their conversations. Developed software product can be used to conduct secure video conference.

For the last four years there has been a videoconferencing link between the Karlskrona hospital and the university hospital of Lund. Because of a need to transmit angiographic films, its use has been gradually expanded to become an everyday routine, used for both elective and emergency examinations. During 1994 and 1995, 1121 cases were examined over the video link. Apart from 156 normal cases all were discussed with surgeons, most at 96 weekly conferences but approximately 50 at conferences taking place as soon as possible after the examination. Assuming that an average of three doctors attended the conferences before the video link was available, this amounts to a saving of 3 8 h in travelling time per videoconference. The average salary was 300 SKr/h and train tickets cost a further 400 SKr per person. The cost of the ISDN connection was approximately 1800 SKr/conference. The net gain was thus about 6500 SKr per videoconference, without taking into account the work that could be done with the doctors still in Karlskrona after the conference.

Conducting realistic interactions while communicating efficiently in online conferences is highly desired but challenging. In this work, we propose a novel pixel-style virtual avatar for interacting with virtual objects in virtual conferences that can be generated in real-time. It consists of a 2D segmented head video stream for real-time facial expressions and a 3D point cloud body for realistic interactions, both of which are generated from RGB video input of a monocular webcam. We obtain a human-only video stream with a human matting method and generate the 3D avatar’s arms with a 3D pose estimation method, which improves the stereoscopic realism and sense of interaction of conference participants while interacting with virtual objects. Our approach fills the gap between 2D video conferences and 3D virtual avatars and combines the advantages of both. We evaluated our pixel-style avatar by conducting a user study; the result proved that the efficiency of our method is superior to other various existing avatar types.

Abstract International communication with different digital tools is now established both at universities and in other contexts worldwide. It is therefore relevant to describe how one of these tools is used in higher education. In the present study the focus is on seminars carried out in student-interactive video-conferences on didactic and pedagogical issues with student teachers. The participants were international and Swedish student teachers at the Department of Education at a Swedish university and at two different campuses. The results are based on analyses of the students’ written reports completed after the seminars and show that the interactive video-conference is useful to establish contacts between students in different places and to develop intercultural understanding of school-related matters. The video-conference is thus a way to work with internationalization in a sustainable way in teacher education, giving opportunities for the exchange of ideas and experiences both at personal and professional levels without mobility.

Background Medical conferences are forums for research, continuing medical education, and networking. Social media is increasingly used for communication and networking due to its low cost and ability to overcome large distances. This study investigates the impact that social media brings to the current conference system. Methods There are three parts of this study: (1) comparing two similar brachial plexus injuries (BPIs) courses without (2009) and with (2017) social media support, and the participants' feedback; (2) sharing our experiences in the management of the 2018 International Course on SuperMicrosurgery (ICSM) conference; and (3) evaluating the studies from the social media platform International Microsurgery Club (IMC), for the consensus pertaining to social media and conference system. Results With the help of social media, international attendance increased during the 2017 BPI conference compared with the 2009 BPI course (25 nationalities in 2009 vs. 35 in 2017). At least 23% obtained their meeting information through social media. Live surgery was the overall main attraction (79%). The 2018 ICSM meeting revealed that video posts increased attendance; videos that were the most effective in attracting (viewership) were either short or pertained to surgical procedures. Facebook, Messenger, and WeChat smartphone applications were effective for immediate communication and troubleshooting among the participants. From the IMC polls, 78% believe that the social media and the conference complemented each other. 97% attended the conference to update their skills and knowledge. Conclusion Social media is a quick and economic tool in promoting medical conferences and instant messenger systems offer immediate communication amongst associates. Despite the popularity of social media, the conference still has its irreplaceable role. The combination of the conference and the social media enhances the training and education of microsurgeons.
