Aiming at the problems of low recommendation accuracy and long recommendation time of the traditional dance art video resource intelligent recommendation system, an intelligent recommendation system of dance art video resource based on the wireless network was designed. In this paper, the hardware part of the smart recommendation system of dance art video resources is designed with the MCU as the system control core, the MAX3232 chip as the hardware transceiver chip, and the RS323 bus circuit. On this basis, according to the user’s existing relationship, a social network is constructed through wireless network technology to obtain user information, Bayesian network is used to predict the user’s preference for dance videos. The probability that users like dance videos is given in the form of data, and related videos of dance art are recommended based on intelligent video resources. The simulation results show that the designed system has higher accuracy and shorter recommendation time for dance art video resources.

ABSTRACTThis article describes the process of developing an educational whiteboard video for community trauma management and transport. Whiteboard videos have become widely used as educational resources for various medical subject matters. These short videos package information concisely through real-time illustration with an accompanying narration. Based on a needs assessment we created a free open access educational resource for community trauma management and transport. A group of interdisciplinary trauma providers partnered in content/script development, video design and dissemination. A third-party production company oversaw video animation and voice-over. The video was disseminated widely through stakeholders and various multimedia channels. We surveyed a sample of our intended audience and the majority of respondents perceived the video to be an effective educational resource. Although cost may represent a potential barrier for producing whiteboard videos, there appears to be a role in creating educational content using this multimedia format.

Abstract Objective Biomedical videos as open educational resources (OERs) are increasingly proliferating on the Internet. Unfortunately, seeking personally valuable content from among the vast corpus of quality yet diverse OER videos is nontrivial due to limitations of today’s keyword- and content-based video retrieval techniques. To address this need, this study introduces a novel visual navigation system that facilitates users’ information seeking from biomedical OER videos in mass quantity by interactively offering visual and textual navigational clues that are both semantically revealing and user-friendly. Materials and Methods The authors collected and processed around 25 000 YouTube videos, which collectively last for a total length of about 4000 h, in the broad field of biomedical sciences for our experiment. For each video, its semantic clues are first extracted automatically through computationally analyzing audio and visual signals, as well as text either accompanying or embedded in the video. These extracted clues are subsequently stored in a metadata database and indexed by a high-performance text search engine. During the online retrieval stage, the system renders video search results as dynamic web pages using a JavaScript library that allows users to interactively and intuitively explore video content both efficiently and effectively. Results The authors produced a prototype implementation of the proposed system, which is publicly accessible at https://patentq.njit.edu/oer . To examine the overall advantage of the proposed system for exploring biomedical OER videos, the authors further conducted a user study of a modest scale. The study results encouragingly demonstrate the functional effectiveness and user-friendliness of the new system for facilitating information seeking from and content exploration among massive biomedical OER videos. Conclusion Using the proposed tool, users can efficiently and effectively find videos of interest, precisely locate video segments delivering personally valuable information, as well as intuitively and conveniently preview essential content of a single or a collection of videos.

Video learning resources are preferred by many students, owing to their intuitiveness and attractiveness. It is of practical significance to study the recommendation methods of video learning resources. Most of the existing research methods treat the scoring matrix as the main element, failing to consider video contents and learner interests. As a result, few of them can realize precise recommendation of videos. To solve the problem, this paper explores the recommendation of micro teaching video resources based on topic mining and sentiment analysis. Firstly, the dialog text features of English dialog videos and learner interest features were mined based on the deep word vector, and a topic mining model was established to achieve similarity-based resource recommendation. Next, the micro teaching videos with text information were subjected to sentiment analysis, improving the pushing accuracy of micro teaching videos. Finally, the scientific nature of our algorithm was demonstrated through experiments.

Power information is an important guarantee for energy security. As an important technical means of safety management and risk control, video monitoring is widely used in the power industry. Power video monitoring system uses efficient processing of multimodal video data and automatically identifies abnormal events and equipment status, replacing human monitoring with machine. Video monitoring data of power substations usually contain both visual information and auditory information, and the data types are diversified. The multimodal video data provides a rich underlying data source for the intelligent monitoring function, but it requires multiple service forms for efficient processing. Most intelligent edge monitoring equipment are only equipped with lightweight computing resources and limited battery supply, limited resources, and weak local processing data capabilities. Power video monitoring system has the characteristics of distribution, openness, interconnection, and intellectualization. Its intelligent edge video equipment is widely distributed, which also brings convenience and also brings security risks in terms of data security and reliability. For the outdoor multimodal power video monitoring system scenario, this paper adopts the edge-cloud distributed system architecture to solve the problem of resource shortage and adopts the first proposed service function virtualization (SFV) to solve the problem of multimodal video data processing. At the same time, the problem of security protection is solved by introducing blockchain to establish trust among intelligent video equipment and service providers. Under the security protection of virtualized service consortium blockchain (VSCB), virtualization technology is introduced into the service function chain (SFC) to realize SFV and solve the resource optimal allocation problem of multimodal video data processing. The work mainly involves the joint mapping of virtual resources, physical resources, and the joint optimization of computing and communication resources. Problems such as large state space and high dimensionality of action space have an impact on resource allocation. The stochastic optimization problem of resource allocation is established as a Markov decision process (MDP) model, and SFV technology is used to optimize cost and delay. The resource allocation optimization algorithm (RAOA-A3C) based on asynchronous advantage actor-critic algorithm (A3C) is proposed. Simulation experiments show that the RAOA-A3C proposed in this paper is more suitable for high-dynamic, multidimensional, and distributed power video monitoring system scenario and has achieved better optimization results in reducing time delay and deployment costs.

The aim of this study was to investigate which of three types of video resources, and which additional resources, were preferred by Information Technology (IT) students for learning and exam preparation. We offered three types of video learning resources to support the delivery of a first year undergraduate IT course. We collated quantitative data on engagement with each video resource through the Learning Management System, drew further insights from an online survey of the students and combined this with data obtained from an institutional student evaluation survey. Whilst there has been much research conducted about the use of video lectures and other online resources, there has been little research conducted specifically with IT students to determine their preferences when selecting learning resources. We report the preferences of IT undergraduate students when provided with a selection of video learning materials, how the resources were used and their perceived learning value. This study not only offers a set of considerations and recommendations for the design of learning materials for IT students, but also for digital learning in higher-education more generally. Short premium videos were watched many more times than full lectures, and 85% of students agreed that short premium videos were more beneficial and effective than longer, lower quality lecture recordings for their learning. The students’ self-assessed video attention span varied greatly, with a mean of 10 minutes. Students perceived that short premium videos helped them to retain knowledge. However, the perceived most useful resource overall was the lecture slides.

Objectives: The aim of this study was to evaluate the content and quality of videos and photos related to the surgery-first approach (SFA) process on YouTube™ and Instagram, one of the social media tools. Materials and Methods: The online video hosting resource YouTube™ and photo hosting resource Instagram were analyzed on March 12, 2020, for photos and videos containing information relevant to SFA. The following three search terms were used in YouTube™: (1) Surgery first; (2) surgery-first approach; and (3) surgery first in orthognathic. The following two hashtags were analyzed in Instagram: #surgeryfirst and #surgeryfirstapproach. Twenty-four videos identified on YouTube™ on the subject of SFA and these videos analyzed with some measurements. A total of 884 videos identified on Instagram on the subject of SFA and these videos and photos analyzed with some measurements. Results: #surgeryfirst and #surgeryfirstapproach hashtags posted by orthodontists or surgeons were had significantly more mean likes than shared by patients and clinics in Instagram. Interaction rate was 2.11 ± 1.01 and viewing rate was 431 ± 1021 in YouTube. YouTube video quality by type of video was comparatively assessed in terms of video and audio quality, and accuracy score. Videos analyzed by an oral and maxillofacial surgeon and an orthodontist and no differences were found. Conclusion: The results of the study show that there is more sharing and data about SFA in Instagram; nevertheless, both YouTube™ and Instagram have now shown to be an insufficient source of information about the surgery-first approach for patients.

Safety professionals looking for information on confined space safety often use the Internet as a resource. YouTube is a popular website that may be used to supplement safety training or as a source of information pertaining to Confined Spaces (CS). YouTube was examined as a source of information on CS safety. YouTube was queried using key phrases “confined space,” “confined space entry,” and “confined space rescue.” Two safety experts reviewed each video and assigned scores for accuracy and view-ability. Of the 220 videos screened, 48 were found to have relevant information about CS safety and were selected for inclusion in the study. Approximately 70.8% of the videos were rated as inaccurate and 87.5% were rated as offering little value. Results of our study suggest that YouTube may currently be an inadequate source of information on CS safety. Safety professionals should verify YouTube video content against trusted agencies such as OSHA before using them as a resource for CS information.DOI: http://dx.doi.org/10.3126/ijosh.v2i1.5626International Journal of Occupational Safety and Health, Vol. 2 No. 1 (2012) 39-42

The Internet, and particularly YouTube, has been found to be and continues to develop as a resourceful educational space for health-related information. Understanding physical literacy as a lifelong health-related outcome and facilitator of an active lifestyle, we sought to assess the content, exposure, engagement, and information quality of uploaded physical literacy videos on YouTube. Two researchers collected 300 YouTube videos on physical literacy and independently coded each video’s: title, media source of upload, content topics related to physical literacy, content delivery style, and adherence to adapted Health on the Net Foundation Code of Conduct (HONcode) principles of information quality. Physical literacy videos that focused on physical activity and behaviors were the strongest predictor of high quality ratings, followed closely by videos covering affective domains (motivation, confidence, and self-esteem) of physical literacy. The content delivery method was also important, with videos utilizing presentations and testimonials containing high quality information about physical activity. Thus, providers of physical literacy and health-related online video content should be aware of and adhere to the expected quality standards. As health information expectations and ethical standards increase, the Internet, and specifically YouTube, has the potential to enhance video resources, virtual networking opportunities, as well as the sharing, dissemination, accumulation, and enrichment of physical literacy information for all.

AbstractWireless multimedia sensor networks (WMSNs) are usually resource constrained, and where the sensor nodes have limited bandwidth, energy, processing power, and memory. Hence, resource mapping is required in a WMSN, which is based on user linguistic quality of service (QoS) requirements and available resources to offer better communication services. This paper proposes an adaptive neuro fuzzy inference system (ANFIS)-based resource mapping for video communications in WMSNs. Each sensor node is equipped with ANFIS, which employs three inputs (user QoS request, available node energy, and available node bandwidth) to predict the quality of the video output in terms of varying number of frames/second with either fixed or varying resolution. The sensor nodes periodically measure the available node energy and also the bandwidth. The spatial query processing in the proposed resource mapping works as follows. (i) The sink node receives the user query for some event. (ii) The sink node sends the query through an intermediate sensor node(s) and cluster head(s) in the path to an event node. A cluster head-based tree routing algorithm is used for routing. (iii) The query passes through ANFIS of intermediate sensor nodes and cluster heads, where each node predicts the quality of the video output. (iv) The event node chooses the minimum quality among all cluster heads and intermediate nodes in the path and transmits the video output. The work is simulated in different network scenarios to test the performance in terms of predicted frames/second and frame format. To the best of our knowledge, the proposed resource mapping is the first work in the area of sensor networks. The trained ANFIS predicts the output video quality in terms of number of frames/second (or H.264 video format) accurately for the given input.

Introduction YouTube is the most widely used video hosting website in the world; however, the quality and reliability of information is unknown. The aim of this study is to evaluate the content and distribution of the most popular videos on YouTube about migraine. Methods We searched for migraine-related videos on the online video hosting resource YouTube ( http://youtube.com/ ). Two authors screened the titles and video descriptions independently for all videos with a view count of ≥ 10,000 views. For each video we recorded descriptive data, the source/author and the primary purpose/content. Results We identified 351 eligible videos. In total, there was more than 3 days of content viewed more than 163 million times. Only 9% of these videos were authored by healthcare professionals. The majority (44%) of videos focused on complementary and alternative medicine. Discussion YouTube provides a wide array of easily accessible information on migraine, ranging from authoritative sources to potentially questionable content. If used uncritically, this may result in inadequate clinical management. Peer-reviewed information on migraine mechanisms and treatment is needed to provide the best available evidence for the public and patients. Ideally, a professional society or foundation such as the International Headache Society would develop, curate, and distribute content.

Digital video, as a kind of large-scale resource, plays an important role in internet’s multimedia resources. Resource consuming is one of the major issues for extracting data from digital video. However, if it is possible to know the outline of a video by browsing several pictures describing it, that will save us a huge amount of time. Up till now, it is not common for video processing system using cloud environment (except video transcoding system). This demo shows an extensible video processing system based on Apache Hadoop cloud environment. Our system utilizes FFmpeg video encoder and OpenCV graphic processor. The basic process of building a video abstracting system includes segmenting scene, followed by exacting representative key frame. The source files of that video stores in HDFS, while the information of segmentation and key frame stores in HBase. In this way, fast searching can be achieved.

The article is devoted to the study of theoretical and methodological principles and practical recommendations for the use of information resource protection technology for the effective functioning of video communication systems. With the development of international relations in society, the introduction of information and telecommunication technologies, Ukraine is actively developing and implementing video conferencing technology, creating and implementing virtual events, webinars, video conferencing and online broadcasts. The use of such systems allows you to get a variety of information, use textual and visual graphics, and so on. For video conferencing systems are relevant threats to information security, which are inherent in any information and telecommunications system. One of the main problems of organizing a reliable video conferencing system is to ensure the optimal data rate at the maximum speed of audio and video processing. The main types of information are considered and the directions of maintaining information security of information and telecommunication systems in accordance with the legislation of Ukraine are determined. The main types of information security are related to the protection of confidentiality, integrity and accessibility and to the confirmation of authorship. To ensure the reliability of the video conferencing system, the protection of open information from unauthorized actions is used, which leads to its accidental or intentional modification or destruction, authorization of users. The tasks of user authorization are management of access rights, collection of statistics and acts as an additional means of ensuring the reliability of the system. Ensuring the protection of information resources is carried out through the use of means and methods of technical protection, implementation of organizational and technical measures of a comprehensive information protection system. Studies of these methods make it possible to distribute the load on all elements of the system in proportion to their resources and characteristics.

Background: Patient demand for education and access to the clinical nurse specialists (CNSs) during the rheumatology clinic at one hospital in Ireland was increasing. Alternative methods of providing patient education had to be examined. Aims: To explore the efficacy of video-based outpatient education, and its impact on demand for the CNSs. Methods: A video was produced to play in a rheumatology outpatient department. A representative sample of 240 patients (120 non-exposed and 120 exposed to the video) attending the clinic was selected to complete a questionnaire exploring the effect of the video. Data were analysed using chi-square tests with Yates' continuity correction. Findings: Demand for the CNSs was six times higher in the non-exposed group compared with the exposed group (non-exposed: 25%, exposed: 4.8%) (χ2=15.7, P=0.00007), representing a significant decrease in resource demand. Conclusion: High-quality educational videos on view in the rheumatology outpatient department provide patients with information sufficient to meet their educational needs, thus releasing CNS resources.

Objective: Vaccine rejection is an important issue affecting human health. As social media platforms are the easiest and most accessible means of accessing information on health, their use has increased significantly. YouTube, is a frequently used video source on health at the global level. We aimed to evaluate the quality of the most watched YouTube videos for COVID-19 vaccine rejection. Methods: The key terms 'COVID vaccine rejection', 'COVID vaccine side effect', 'COVID vaccine refuse' was used for the videos. The reliability of the videos was assessed using the modified DISCERN scale. The Global Quality Scale (GQS) was used to evaluate the videos in terms of vaccine information. According to the results of the scale, the videos were divided into three groups as good/excellent quality, moderate quality and poor quality. Results: The videos were 30.4% (n=21) of good/excellent quality, 34.8% (n=24) of moderate quality, and 34.8% (n=24) of poor quality. Good/excellent videos had a significantly higher median DISCERN score (p<0.01). There was no significant difference between daily median views (p=0.779), daily comments (p=0.148) and likes rates (p=0.551) according to video quality. Conclusion: E-source; Youtube contains a significant amount of data on health-related services. However, some of this information is inaccurate or of insufficient quality. Physicians should warn their patients when using digital resources, direct them to the right resources, and demonstrate the importance of digital resource evaluation.

This paper considers how information sheets are used as a resource for joint attention and decision-making in a situated service encounter. The optician shop is a perspicuous setting for addressing decision-making as an interactional accomplishment informed by information sheets, because they are routinely used and made relevant by sellers. The paper builds on ethnomethodological multimodal conversation analysis and a large corpus of more than 700 hours of video recordings from eleven different Danish optician shops. Based on one single analysis from this corpus, the paper shows how the sheet is used cooperatively and oriented to in situ as a shared resource in the process of selling/buying glasses. A key finding is that the information sheet is not just a resource for the seller but a shared resource for established joint attention and decision-making. More generally, the paper contributes to studies of service and sales encounters by highlighting the importance of inscribed objects to decision-making processes in social interaction.

At present, wireless network technology is advancing rapidly, and intelligent equipment is gradually popularized, which rapidly developed the mobile streaming media business. All kinds of mobile video applications have enriched people’s lives by carrying huge traffic randomly. Wireless networks (WNs) are facing an unprecedented burden, which allocates very important wireless video resources. Similarly, in WNs, the network status is dynamic and the terminal is heterogeneous, which causes the traditional video transmission system to fail to meet the needs of users. Hence, Scalable Video Coding (SVC) has been introduced in the video transmission system to achieve bit rate adaptation. However, in a strictly hierarchical traditional computer network, the wireless resource allocation strategy usually takes throughput as the only way to optimize the target, and it is terrible to make more optimizations for scalable video transmission. This article proposed a cross-layer design to enable information to be transmitted between the wireless base station and the video server to achieve joint optimization. To improve users’ satisfaction with video services, the wireless resource allocation problem and the video stream scheduling problem are jointly considered, which keep the optimization space larger. Based on the proposed architecture, we further study the design of wireless resource allocation algorithms and rate-adaptive algorithms for the scenario of multiuser transmission of scalable video in the Long-Term Evolution (LTE) downlink. Experimental outcomes have shown substantial performance enhancement of the proposed work.

Background: In Australia, women with metastatic breast cancer are not systematically made aware of or helped to access supportive care resources. Finding resources tailored to their needs can be challenging as they spread across several healthcare and advocacy organizations. Furthermore, resources assume varying levels of knowledge about the disease and its treatments, are fragmented and are dispersed across multiple organizations. Aim: The aim of our study was to codesign a signpost resource to direct women to key supportive care organizations that provide relevant, timely and comprehensive support for them; ensure women are made aware of and know how to access support they need, as and when they need it; and ensure that health professionals are aware of the resource, support its use, and distribute it to women. Methods: Using a codesign framework, initial development of the resource was guided by consumer representation on the study Steering Group. The resource was then presented to women living with metastatic breast cancer, and their advice obtained about its relevance and functionality during semistructured interviews. Purposive sampling based on age, time since diagnosis and geographical location (metro/regional), was used to obtain a variety of perspectives. Open-ended questions explored what the resource should contain, look like, and how it could best be introduced and distributed. An iterative descriptive analytical approach was applied. Results: Seven women aged 40-61 years were interviewed. Time since their metastatic breast cancer diagnosis ranged from 5 months to 19 years. Women told us about their preferences for style, content and format for the resource. They also guided discussion about how best to promote the resources in a way that both informed health professionals but also empowered women to find and express a need for support. As a result, 2 videos were produced. In the first 3-minute video for health professionals, consumers powerfully convey messages about the impact of their diagnosis, their need for support and how important it is for health professionals to “value and believe there are emotional, social and material aspects of coping with the disease” (this video will be shared in the presentation). In the second 4-minute video, consumers endorse the need for information and support, and women and consumers watching the video are introduced to the services provided by supportive care organizations profiled on the resource. Conclusion: Resources created and tailored by consumers for consumers are powerful and important. Consumer-led interventions that demonstrate to health professionals the importance of supportive care as a cornerstone of excellent cancer care may have a considerable impact but require empirical testing.

Video streaming has become a kind of main information carried by Unmanned Aerial Vehicles (UAVs). Unlike single transmission, when a cluster of UAVs execute the real-time video shooting and uploading mission, the insufficiency of wireless channel resources will lead to bandwidth competition among them and the competition will bring bad watching experience to the audience. Therefore, how to allocate uplink bandwidth reasonably in the cluster has become a crucial problem. In this paper, an intelligent and distributed allocation mechanism is designed for improving users’ video viewing satisfication. Each UAV in a cluster can independently adjust and select its video encoding rate so as to achieve flexible uplink allocation. This choice relies neither on the existence of the central node, nor on the large amount of information interaction between UAVs. Firstly, in order to distinguish video service from ordinary data, a utility function for the overall Quality of Experience (QoE) is proposed. Then, a potential game model is built around the problem. By a distributed self-learning algorithm with low complexity, all UAVs can iteratively update their own bandwidth strategy in a short time until equilibria, thus achieving the total quality optimization of all videos. Numeric simulation results indicate, after a few iterations, that the algorithm converges to a set of correlation equilibria. This mechanism not only solves the uplink allocation problem of video streaming in UAV cluster, but also guarantees the wireless resource providers in distinguishing and ensuring network service quality.

The evolution of electronic information technologies in a Midwest state in the USA are discussed and this evolution is compared to national trends for processing information. Information management technologies are now in the third stage of evolution. Over the next five years, the technology for handling information will fully integrate voice, data, and video technologies. This integration has profound implications for how organizations manage its enactment and how organizations will adapt to their internal and external environments. In order to manage these enactments and adaptations, a new way of planning is required. Traditional “bottom up” and “top down” planning methodologies must be integrated into a planning method that defines the knit between information system architectures and resources with corporate policies and business plans. The article presents a model of this integrated planning approach for practitioners and policy makers who are responsible for designing organizational systems.

Analyzed is, how widely and effectively information and communication technologies are used at the higher educational system. As a result of the study, it was found that in the process of distance learning students who belong to high and medium resource groups are more motivated, creative and efficient than students from families who belong to low resource groups. It has been determined that the main advantages of the distance learning format are the possibility of implementing individual educational trajectories of students, improving communication and the effectiveness of interaction between students and teachers, the ability to invite experts and practitioners to classes online, creating a more open and friendly educational environment. The study revealed the preferred forms of distance learning. Students from families who belong to highly resource groups, for the most part, believe that distance work of a teacher and student should be implemented mainly in the form of synchronous learning. Students from families who belong to medium resource and low resource groups generally prefer the format of asynchronous learning (recording lectures) and expanding students' independent work. Analyzed digital educational resources used by students of different groups. Regardless of gender, age, course of study and university, students widely use the digital educational resources of CyberLeninka. At the same time, it was found that students from families who belong to highly resource groups systematically turn to other digital educational resources: video lectures from Harvard and Stanford Universities. Based on the results of the study, measures are proposed to improve the effectiveness of distance learning at the university.

The Earth's aerospace monitoring (ASM) systems use state-of-the-art integrated information technologies that include radio-based detection and surveillance systems using telecommunications. One of the main tasks of ASM systems is to increase the efficiency of decision-making necessary for the timely prevention, detection, localization and elimination of crisis situations and their probable consequences. Modern conditions impose stricter requirements for efficiency, reliability and quality of the provided video data. To ensure compliance with the requirements, it is necessary to provide the appropriate capabilities of the onboard equipment. On the basis of the existing information and communication systems it is necessary to carry out: continuous or periodic assessment of a condition of objects of supervision and control; continuous (operational) collection, reception, transmission, processing, analysis and display of information resources. It is proposed to use UAVs (unmanned aerial vehicles) as a means to perform ASM tasks. The time of organizing communication sessions and delivery of information should vary from a few seconds to 2.5 hours. Untimely processing and delivery of a specific information resource in the management process leads to its obsolescence or loss of relevance, which contributes to erroneous decisions. One way to reduce time is to encode the data. To do this, it is proposed to use video compression algorithms. However, based on the analysis of the possibility of modern methods of video information compression, taking into account the specifics of the onboard equipment of the UAV, the coding problem is not completely solved. The research results show the expediency of using an improved method of video information compression to reduce the computing resources of the software and hardware complex of the onboard UAV equipment and to ensure the requirements for efficiency and reliability of data in modern threats to ASM systems as a whole.

Background:There are reported concerns of patient misunderstanding of the COVID-19 pandemic and vaccination safety. It is particularly important that these are understood in patients taking complex immunusuppressive therapies. Rapid delivery of targeted and up-to-date video messages from clinicians sent directly to patients could address patient uncertainty, and improve COVID-19 vaccination uptake. Innovative SMS (short message service) based video message has already shown promise in delivering COVID-19 information to patients [1]. We present our experience in creating a tailored vaccine information video sent directly to our large cohort of patients in the UK with a range of rheumatic diseases and report on the learning points going forward.Objectives:Our three objectives were: (1) educate our patients using an interactive mobile video information resource outlining the safety of the COVID vaccination in these patient groups; (2) better understand our patients’ views of the COVID-19 vaccine; (3) evaluate the patient experience of this approach.Methods:We designed and recorded an 8-minute interactive web-based video delivered education resource designed for mobile phones. This included: aims of the video; details of licenced vaccines; UK vaccination schedule; frequently asked questions; links to national charity resources; our clinician recommendations; a rheumatologist being vaccinated; case studies; and summary data. We produced a simple mobile phone web-based evaluation of the resource, including anonymised patient demographics, their understanding of the safety of the vaccine pre/ post video, and their user experience. Resource and evaluation were piloted by local healthcare professionals, our Patient Participation Group, a national charity, and approved by senior management. We distributed this to our follow-up patient cohort via our hospital SMS provider on 21.12.20, at the start of roll-out of UK vaccines, containing a link to the resource and evaluation.Results:Of a cohort of 10,981 patients, we had 8886 mobile phone numbers. At Day 14, we recorded 2358 video views (26.3%) and 664/2358 completed evaluations (28.1%). Only one person reported being unable to watch the video. Before watching the video, 348/664 patients (52.4%) were unsure if the vaccine was safe and/or recommended for them, rising to 626/664 (94.3%) post-video.Reasons for uncertainty after the video (38/664) included drug allergy and fertility concerns. Following the video, 509/664 patients (76.6%) reported that they were more likely to have the vaccination. The majority of the patients (614/660, 93.0%) agreed that the method was a helpful method to share such information.Age distribution of our whole cohort, patients with mobile phones, and responders were similar: Age >50 was 80.4%,76.3%,and 88.6% respectively. A large proportion was treated with immunosuppressive medication (61.3% conventional DMARD, 39.4% biological DMARD and 17.6% corticosteroids). Gender and case mix for responders were similar to published data from our cohort: female 74.0%; rheumatoid arthritis commonest disease (389/664, 58.5%).Conclusion:To our knowledge, this is the first study to show the potential for SMS linked interactive multimedia message for patient education. The multimedia component allows users to easily navigate to relevant sections, and access a choice of linked resources. We demonstrate this low-cost technology is simple, effective and well placed to assist physicians in educating patients during a time when face-to-face contact is proving to be difficult. We have shown high levels of patient satisfaction, reassurance, and self-reported behaviour change. Such technology has potential utility for national bodies, primary and secondary care groups, and merits further research.References:[1]The Lancet Rheumatology.

With the advent of the information age and the continuous updating of modern educational methods, the learning form of schools has developed into a diversified structure, and the status of network teaching in the modern educational mechanism has also been continuously improved, achieving irreplaceable results in modern teaching. The advantages of network teaching in its breadth and ubiquity have been recognized and now accepted by students. At present, most of the schools relax students’ study areas and increase students’ interest in self-directed learning. A good online teaching method is an educational method formed by comprehensive use of modern educational technology. To sum up, it is imperative to develop a system that is suitable for schools to manage many dance resource websites. The dance resource information management platform organically integrates related digital resources around a certain theme to form a resource combination covering text, pictures, audio, video, and other types of materials, specifically related to content associations and subject indexing. This dance digital resource information can be revealed from multiple dimensions through the information system. It is convenient for users to retrieve and browse various information. This method facilitates the interaction between teachers and students, thereby greatly improving the utilization rate of digital information resources. The three-dimensional teaching of dance classroom is realized. Through the platform, a wealth of characteristic dance resource information can be collected from all over the world. Through the system’s reorganization of dance information, value-added services of characteristic dance resources are realized, making the dance material novel and professional. The system has strong operability and practicability to achieve the integration of teaching design and diversification of learning applications.

Introduction: To investigate the quality of information offered by videos on YouTube™ for those individuals seeking information regarding risks associated with orthodontic treatment. The quality of information was compared the British Orthodontic Society (BOS) patient information leaflet ‘Orthodontic treatment- what are the risks’.
Materials and Method: YouTube™ was searched systematically for videos on orthodontic treatment risks using the terms ‘orthodontic risks’ and ‘braces risks’. Videos were selected based on a strict inclusion and exclusion criteria and demographics recorded. Completeness was assessed using a 8-point score based on the BOS patient information leaflet ‘Orthodontic treatment- what are the risks’. Descriptive statistics and statistical analysis using correlation tests were generated.
Result: 19.2% videos met the specified criteria with 80.8% videos excluded. Videos varied in regards to completeness with the mean completeness score of 3 and only 13% meeting all criteria. The risk of pain and discomfort was most commonly included orthodontic risk 61%. No statistical significance was found for completeness of the video with viewers interaction (R = 0.2665, P=0.219897) viewing rate (R=0.1138, P=0.617326) or length of video (R=0.0062, P= 0.977601).
Conclusion: YouTube™ generally hosts videos with low completeness with regards to orthodontic treatment risks. Therefore, orthodontists should be aware of this resource and caution patients regarding the comprehensiveness of information. In addition to the potentially misleading content which is avail-able within YouTube™ videos

Background People with gestational diabetes have enhanced learning requirements during pregnancy, and management of their disease often requires the translation of health information into new health behavior changes. Seeking information from the internet to augment learning from health professionals is becoming more common during pregnancy. YouTube is a popular free and accessible web-based resource, which may be particularly useful for individuals with low health literacy or other barriers to receiving high-quality health care; however, the quality and content of YouTube videos varies, and little is known about those covering gestational diabetes. Objective We aimed to systematically evaluate the quality, content, and reliability of YouTube videos about gestational diabetes. Methods A systematic search of YouTube videos was conducted over the course of 1 week in April 2020 using the following keywords: “gestational diabetes,” “gestational diabetes management,” “gestational diabetes treatment,” and “pregnancy and diabetes.” The search results were displayed by relevance, replicating a default YouTube search attempt. The first 60 results from each keyword were reviewed (n=240). Exclusion criteria were videos unrelated to gestational diabetes, videos not in English, and those for which the full video was not available at the time of review. For each unique video, a gestational diabetes content score was used to rate video comprehensiveness and accuracy, and the DISCERN instrument, a validated metric to assess consumer health information, was used to evaluate the reliability of information presented. Videos were further categorized by quality: videos with DISCERN scores lower than 3 (out of 5) or a content score less than 4 (out of 7) were categorized as low quality, and all others were designated high quality. We performed descriptive analysis and compared video characteristics by source and quality rating. Results For 115 unique videos, the mean content score (out of 7) was 3.5 (SD 2.0) , and the mean DISCERN score (out of 5) was 2.7 (SD 0.7), representing low to moderate information comprehensiveness and reliability respectively. Video sources were categorized as personal vlog (12/115, 10.4%), web-based education (37/115, 32.2%), medical (52/115, 45.2%), business or company (13/115, 11.3%), and media clip (1/115, 0.9%). DISCERN and content scores trended higher among medical and web-based education videos. The majority of videos (n=88) were categorized as low quality, while 27 videos were categorized as high quality. Video duration was longer for high-quality videos (P<.001); high- and low-quality videos otherwise had similar views and viewer interaction numbers. Conclusions Although high-quality videos about gestational diabetes exist, reliability, accuracy, and comprehensiveness were low overall, and higher quality was not associated with increased viewer interaction. It is important to acknowledge the limitations of this platform and to assist patients in accessing high quality content and differentiating the quality of information sources.

Blockchain technology is widely used in the field of digital right protection technology. The traditional digital right protection scheme is not only inefficient and highly centralized but also has the risk of being modified. Due to its own characteristics, blockchain cannot completely store all the original files of digital resources. In this paper, a convolutional neural network algorithm based on visual priority rule is proposed (CNNVP). This algorithm can recognize facial expressions in the original files of digital resources (for short video of face class). The algorithm extracts facial expression features accurately and makes these features form log files that can represent the original files of digital resources. Then, the paper proposes a short video copyright storage algorithm based on blockchain and facial expression recognition and stores the log file into the blockchain. The above methods not only improve the efficiency of short video copyright storage, reduce the degree of storage centralization, and eliminate the risk that copyright is easy to be modified. Moreover, the computing operation of deep learning technology on short video not only ensures the privacy of storage certificate information but also ensures the possibility of blockchain storage of video information. Experiments show that the algorithm proposed in this paper is more efficient than the traditional copyright storage method. Moreover, the algorithm proposed in this paper can provide technical support to the media resource management department.

In the process of scientific research, communication is essential. The insertion of Information and Communication Technologies have modified the profile of the researchers and the daily life of their researches. In response to these changes, this article proposes the adoption at scientific events of the video poster, replacing the poster on paper or canvas. The objective is to propose a model of Management of Open Scientific Information of Video in Events, as a means of scientific communication. This research was developed based on the literature review of models of this type of management, the information collected in interviews with the managers of the events that used the video poster as a strategy of scientific communication, and the data collected through a survey, sent to event participants. The results, after treatment of the data and confrontation of the ideas of the managers with the opinions of the participants, point out that the video poster has the potential to prolong and even perpetuate the products of scientific communication in events and to promote the scientific divulgations, besides the possibility of reuse, as an educational resource. As result of the research, the proposal of an open scientific information management model for the use of event managers is presented.

We present a framework for cross-layer optimized real time multiuser encoding of video using a single layer H.264/AVC and transmission over MIMO wireless channels. In the proposed cross-layer adaptation, the channel of every user is characterized by the probability density function of its channel mutual information and the performance of the H.264/AVC encoder is modeled by a rate distortion model that takes into account the channel errors. These models are used during the resource allocation of the available slots in a TDMA MIMO communication system with capacity achieving channel codes. This framework allows for adaptation to the statistics of the wireless channel and to the available resources in the system and utilization of the multiuser diversity of the transmitted video sequences. We show the effectiveness of the proposed framework for video transmission over Rayleigh MIMO block fading channels, when channel distribution information is available at the transmitter.

Through the advent of digital information, information security has taken on a vital role. Use of the internet freely for contact has increased the attacks on users. Data protection is the present problem relating to privacy and security during storage and communication. This paper deals with a multilayered protected channel's proposal to transfer confidential data/video through a channel. The hidden video is initially encrypted using the algorithm NOLSB. The created cipher video is hidden in a larger sized video file. In addition, this video file is encrypted using the (m, k) firm technique to optimize resource efficiency and bandwidth optimization. Video shares are then sent through all the network's channels to ensure security. This approach ensures that video files could be retrieved at the end receiver even though any shares were lost over the network, without the sender needing to resend the video file.

Video data generated from wearable cameras is now available online, as the concept of “lifelogging” has been introduced to many citizens due to the spread of wearable camera equipment. Usually, these wearable cameras automatically capture images or record videos from a first-person point of view; they collect a new form of information that cannot be captured through other means. Citizen data Harvest in Motion Everywhere (CHIME) project pays close attention to the value of this new type of resource, particularly regarding the video data that cyclists record using wearable cameras over a long period of time. These contextually rich data capture community members’ infrastructure experiences and interactions with other transit modes, as well as environmental changes. If curated and made publicly accessible, there is great potential for various stakeholders, including public historians, researchers, city planners, and citizens, to use the data. However, making these videos open to the public and to researchers raises ethics issues, as the data include sensitive, location-based information that may intrude into private lives. Additionally, the videos include the accidental collection of data from secondary participants (bystanders). In this paper, we will describe the potential value of citizen-generated video data using the CHIME project example and discuss the privacy and ethical considerations related to the use of this type of data for scientific and citizen research.

Abstract. In an effort to quantify message complexity in such a way that predictions regarding the moment-to-moment cognitive and emotional processing of viewers would be made, Lang and her colleagues devised the coding system information introduced (or ii). This coding system quantifies the number of structural features that are known to consume cognitive resources and considers it in combination with the number of camera changes (cc) in the video, which supply additional cognitive resources owing to their elicitation of an orienting response. This study further validates ii using psychophysiological responses that index cognitive resource allocation and recognition memory. We also pose two novel hypotheses regarding the confluence of controlled and automatic processing and the effect of cognitive overload on enjoyment of messages. Thirty television advertisements were selected from a pool of 172 (all 20 s in length) based on their ii/cc ratio and ratings for their arousing content. Heart rate change over time showed significant deceleration (indicative of increased cognitive resource allocation) for messages with greater ii/cc ratios. Further, recognition memory worsened as ii/cc increased. It was also found that message complexity increases both automatic and controlled allocations to processing, and that the most complex messages may have created a state of cognitive overload, which was received as enjoyable by the participants in this television context.

Wireless data traffic, especially video traffic, continues to increase at a rapid rate. Innovative network architectures and protocols are needed to improve the efficiency of data delivery and the quality of experience (QoE) of mobile users. Mobile edge computing (MEC) is a new paradigm that integrates computing capabilities at the edge of the wireless network. This paper presents a computation-capable and programmable wireless access network architecture to enable more efficient and robust video content delivery based on the MEC concept. It incorporates in-network data processing and communications under a unified software-defined networking platform. To address the multiple resource management challenges that arise in exploiting such integration, we propose a framework to optimize the QoE for multiple video streams, subject to wireless transmission capacity and in-network computation constraints. We then propose two simplified algorithms for resource allocation. The evaluation results demonstrate the benefits of the proposed algorithms for the optimization of video content delivery.
