    This report describes the incorporation of digital learning elements in organic chemistry and biochemistry courses. The first example is the use of pen-based technology and a large-format PowerPoint slide to construct a map that integrates various metabolic pathways and control points. Students can use this map to visualize the integrated nature of metabolism and how various hormones impact metabolic regulation. The second example is the embedding of health-related YouTube videos directly into PowerPoint presentations. These videos become a part of the course notes and can be viewed within PowerPoint as long as students are online. The third example is the use of a webcam to show physical models during online sessions using web-conferencing software. Various molecular conformations can be shown through the webcam, and snapshots of important conformations can be incorporated into the notes for further discussion and annotation. Each of the digital learning elements discussed in this report is an attempt to use technology to improve the quality of educational resources available outside of the classroom to foster student engagement with ideas and concepts.

    1995-03-01

    Packet-switching based video conferencing has emerged as one of the most important multimedia applications. Lip synchronization can be disrupted in the packet network as the result of the network properties: packet delay jitters at the capture end, network delay jitters, packet loss, packet arrived out of sequence, local clock mismatch, and video playback overlay with the graphic system. The synchronization problem become more demanding as the real time and multiparty requirement of the video conferencing application. Some of the above mentioned problem can be solved in the more advanced network architecture as ATM having promised. This paper will present some of the solutions to the problems that can be useful at the end station terminals in the massively deployed packet switching network today. The playback scheme in the end station will consist of two units: compression domain buffer management unit and the pixel domain buffer management unit. The pixel domain buffer management unit is responsible for removing the annoying frame shearing effect in the display. The compression domain buffer management unit is responsible for parsing the incoming packets for identifying the complete data blocks in the compressed data stream which can be decoded independently. The compression domain buffer management unit is also responsible for concealing the effects of clock mismatch, lip synchronization, and packet loss, out of sequence, and network jitters. This scheme can also be applied to the multiparty teleconferencing environment. Some of the schemes presented in this paper have been implemented in the Multiparty Multimedia Teleconferencing (MMT) system prototype at the IBM watson research center.

    One of the applications of modern technology in telemedicine is video conferencing. An alternative to traveling to attend a conference or meeting, video conferencing is becoming increasingly popular among hospitals. By using this technology, doctors can help patients who are unable to physically visit hospitals. Video conferencing particularly benefits patients from rural areas, where good doctors are not always available. Telemedicine has proven to be a blessing to patients who have no access to the best treatment. A telemedicine system consists of customized hardware and software at two locations, namely, at the patient's and the doctor's end. In such cases, the video streams of the conferencing parties may contain highly sensitive information. Thus, real-time data security is one of the most important requirements when designing video conferencing systems. This study proposes a secure framework for video conferencing systems and a complete management solution for secure video conferencing groups. Java Media Framework Application Programming Interface classes are used to design and test the proposed secure framework. Real-time Transport Protocol over User Datagram Protocol is used to transmit the encrypted audio and video streams, and RSA and AES algorithms are used to provide the required security services. Results show that the encryption algorithm insignificantly increases the video conferencing computation time.

    Full Text Available Recent major political uprisings are indicating the extent to which social learning Web 2.0 technologies, can infl uence change in informal learning settings. Recognition and a discussion of the potential of that infl uence in formal learning settings have only just begun. This article describes a study of an international distance learning project in 2004, using a variety of Web 2.0 technologies, including video-based web conferencing, that sought to initiate and respond to this urgent need for dialogue in the research. Self-selected participants took part in a 5-week English as a foreign language (EFL program, a joint NATO sponsored Canadian and Romanian Ministry of Defense-supported initiative. Clear evidence of linguistic knowledge construction and of important changes to participants’ learner identities, indicates the power of these technologies to support the kind of learning that can lead to the development of global citizens and the skills they will increasingly require in the 21st century.

    Harold Ogren

    For those of us who are teaching at a university, coming to CERN for a week means that someone else has to be found to teach our course. Recently, thanks to an initiative of CERN's Education Group who in collaboration with the IT department have buit a Remote Video Conference (VC) room for outreach communication with schools, I have been able to test teaching class back home whilst at the same time being at CERN! On Monday October 5, at 16:00, (10:00 at Indiana University), I attempted my first remote class. Of course, I could not do this alone. Back in the main auditorium in the physics Department, Hal Evans and Fred Luehring had rolled in a portable teleconference center, set up lecture demos and started a class computer. At CERN, Knut Bjorkli had the teaching center teleconference screen active, and had also connected to my class website when I arrived. The first day startup was a bit rocky - there were fire wall problems (?) that required that we connect to the Indiana VC unit rather than the other way a...

    Although video-based teleconferencing is becoming more widespread in the medical profession, especially for scheduled consultations, applications for rapid assessment of acute medical problems are rare. Use of such a video system in a nursing facility may be especially beneficial, because physicians are often not immediately available to evaluate patients. We have assembled and tested a portable, wireless conferencing system to prepare for a randomized trial of the system s influence on resource utilization and satisfaction. The system includes a rolling cart with video conferencing hardware and software, a remotely controllable digital camera, light, wireless network, and battery. A semi-automated paging system informs physicians of patient s study status and indications for conferencing. Data transmission occurs wirelessly in the nursing home and then through Internet cables to the physician s home. This provides sufficient bandwidth to support quality motion images. IPsec secures communications. Despite human and technical challenges, this system is affordable and functional.

  6. Video Conferencing for Opening Classroom Doors in Initial Teacher Education: Sociocultural Processes of Mimicking and Improvisation

    2010-11-01

    Full Text Available In this article, we present an alternative framework for conceptualising video-conferencing uses in initial teacher education and in Higher Education (HE more generally. This alternative framework takes into account the existing models in the field, but – based on a set of interviews conducted with teacher trainees and wider analysis of the related literature – we suggest that there is a need to add to existing models the notions of ‘mimicking’ (copying practice and improvisation (unplanned and spontaneous personal learning moments. These two notions are considered to be vital, as they remain valid throughout teachers’ careers and constitute key affordances of video-conferencing uses in HE. In particular, we argue that improvisational processes can be considered as key for developing professional practice and lifelong learning and that video-conferencing uses in initial teacher education can contribute to an understanding of training and learning processes. Current conceptualisations of video conferencing as suggested by Coyle (2004 and Marsh et al. (2009 remain valid, but also are limited in their scope with respect to focusing predominantly on pragmatic and instrumental teacher-training issues. Our article suggests that the theoretical conceptualisations of video conferencing should be expanded to include elements of mimicking and ultimately improvisation. This allows us to consider not just etic aspects of practice, but equally emic practices and related personal professional development. We locate these arguments more widely in a sociocultural-theory framework, as it enables us to describe interactions in dialectical rather than dichotomous terms (Lantolf & Poehner, 2008.

    Conventional video conferencing (e.g. Skype with a webcam) suffers from some fundamental flaws that keep it from attaining a true sense of immersivity and copresence and thereby emulating a real face-to-face conversation. Not in the least does it not allow its users to look directly into each other’s eyes. The webcam is usually set up next to the screen or at best integrated into the bezel. This forces the user to alternate his gaze between looking at the screen to observe his remote conferen...

    Full Text Available Mobile phones and related gadgets in networks are omnipresent at our students, advertising itself as the platform for mobile, pervasive learning. Currently, these devices rapidly open and enhance, being soon able to serve as a major platform for rich, open multimedia applications and communication. In this report we introduce a video conferencing software, which seamlessly integrates mobile with stationary users into fully distributed multi-party conversations. Following the paradigm of flexible, user-initiated group communication, we present an integrated solution, which scales well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants. This approach allows for a spontaneous, location independent establishment of video dialogs, which is of particular importance in interactive learning scenarios. The work is based on a highly optimized realization of a H.264 codec.

    To describe experiences, lessons and the implications related to the use of conferencing technology to support three drug policy research groups within a three-year period, using the action case research method. An action case research field study was executed. Three different drug policy groups participated: research, educator, and decision-maker task groups. There were a total of 61 participants in the study. The study was conducted between 2004 and 2007. Each group used audio-teleconferencing, web-conferencing or both to support their knowledge exchange activities. Data were collected over three years and consisted of observation notes, interviews, and meeting transcripts. Content analysis was used to analyze the data using NIVIO qualitative data analysis software. The study found six key lessons regarding the impact of conferencing technologies on knowledge exchange within drug policy groups. We found that 1) groups adapt to technology to facilitate group communication, 2) web-conferencing communication is optimal under certain conditions, 3) audio conferencing is convenient, 4) web-conferencing forces group interactions to be "within text", 5) facilitation contributes to successful knowledge exchange, and 6) technology impacts information sharing. This study highlights lessons related to the use of conferencing technologies to support distant knowledge exchange within drug policy groups. Key lessons from this study can be used by drug policy groups to support successful knowledge exchange activities using conferencing technologies. 2010 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background Teamwork is important for patient care and outcome in emergencies. In rural areas, efficient communication between rural hospitals and regional trauma centers optimise decisions and treatment of trauma patients. Little is known on potentials and effects of virtual team to team cooperation between rural and regional trauma teams. Methods We adapted a video conferencing (VC system to the work process between multidisciplinary teams responsible for trauma as well as medical emergencies between one rural and one regional (university hospital. We studied how the teams cooperated during simulated critical scenarios, and compared VC with standard telephone communication. We used qualitative observations and interviews to evaluate results. Results The team members found VC to be a useful tool during emergencies and for building "virtual emergency teams" across distant hospitals. Visual communication combined with visual patient information is superior to information gained during ordinary telephone calls, but VC may also cause interruptions in the local teamwork. Conclusion VC can improve clinical cooperation and decision processes in virtual teams during critical patient care. Such team interaction requires thoughtful organisation, training, and new rules for communication.

    Hofflander, Malin; Nilsson, Lina; Eriksén, Sara; Borg, Christel

    2016-03-01

    This article describes healthcare managers' experiences of leading the implementation of video conferencing in discharge planning sessions as a new tool in everyday practice. Data collection took place through individual interviews and the interviews were analyzed using qualitative content analysis with an inductive approach. The results indicate that managers identified two distinct leadership perspectives when they reflected on the implementation process. They described a desired way of leading the implementation and communicating about the upcoming change, understanding and securing support for decisions, as well as ensuring that sufficient time is available throughout the change process. They also, however, described how they perceived that the implementation process was actually taking place, highlighting the lack of planning and preparation as well as the need for support and to be supportive, and having the courage to adopt and lead the implementation. It is suggested that managers at all levels require more information and training in how to encourage staff to become involved in designing their everyday work and in the implementation process. Managers, too, need ongoing organizational support for good leadership throughout the implementation of video conferencing in discharge planning sessions, including planning, start-up, implementation, and evaluation.

    Full Text Available Recently, in the distance learning system, video conferencing becomes one of expected course material delivery systems for creating a virtual class such that lecturer and student which are separated at long distance can engage a learning activity as well as face to face learning system. For this reason, the service availability and quality should be able to guaranteed and fulfilled. In this research, we analyze QoS of video conferencing between main campus and sub campus as the implementation of distance learning system in laboratory scale. Our experimental results show that the channel capacity or bandwidth of WAN connection between main campus and sub campus at 128 kbps is able to generate the throughput of video transmission and reception at 281 kbps and 24 kbps, respectively. Meanwhile, throughput of audio transmission and reception is 64 kbps and 26 kbps with the number of total packet loss for video and audio transmission is 84.3% and 29.2%, respectively. In this setting, the total jitter for video and audio transmission is 125 ms and 21 ms, respectively. In this case, there is no packet loss for traffic transmitting and receiving with jitter is not more than 5 ms. We also implemented QoS using Trust CoS model dan Trust DSCP for improving the quality of service in term of jitter up to 12.3% and 22.41%, respectively.

    Akihiko Sugiura

    2012-01-01

    Full Text Available A user’s position-specific field has been developed using the Global Positioning System (GPS technology. To determine the position using cellular phones, a device was developed, in which a pedestrian navigation unit carries the GPS. However, GPS cannot specify a position in a subterranean environment or indoors, which is beyond the reach of transmitted signals. In addition, the position-specification precision of GPS, that is, its resolution, is on the order of several meters, which is deemed insufficient for pedestrians. In this study, we proposed and evaluated a technique for locating a user’s 3D position by setting up a marker in the navigation space detected in the image of a cellular phone. By experiment, we verified the effectiveness and accuracy of the proposed method. Additionally, we improved the positional precision because we measured the position distance using numerous markers.

  6. Initial experience at a university teaching hospital from using telemedicine to promote education through video conferencing

    Bruno Monteiro Tavares Pereira

    Full Text Available CONTEXT AND OBJECTIVE: Telehealth and telemedicine services are advancing rapidly, with an increasing spectrum of information and communication technologies that can be applied broadly to the population's health, and to medical education. The aim here was to report our institution's experience from 100 videoconferencing meetings between five different countries in the Americas over a one-year period. DESIGN AND SETTING: Retrospective study at Universidade Estadual de Campinas. METHODS: Through a Microsoft Excel database, all conferences in all specialties held at our institution from September 2009 to August 2010 were analyzed retrospectively. RESULTS: A total of 647 students, physicians and professors participated in telemedicine meetings. A monthly mean of 8.3 (± 4.3 teleconferences were held over the analysis period. Excluding holidays and the month of inaugurating the telemedicine theatre, our teleconference rate reached a mean of 10.3 (± 2.7, or two teleconferences a week, on average. Trauma surgery and meetings on patient safety were by far the most common subjects discussed in our teleconference meetings, accounting for 22% and 21% of the total calls. CONCLUSION: Our experience with telemedicine meetings has increased students' interest; helped our institution to follow and discuss protocols that are already accepted worldwide; and stimulated professors to promote telemedicine-related research in their own specialties and keep up-to-date. These high-technology meetings have shortened distances in our vast country, and to other reference centers abroad. This virtual proximity has enabled discussion of international training with students and residents, to increase their overall knowledge and improve their education within this institution.

  8. Video as a technology for interpersonal communications: a new perspective

    Science.gov (United States)

    Whittaker, Steve

    1995-03-01

    Some of the most challenging multimedia applications have involved real- time conferencing, using audio and video to support interpersonal communication. Here we re-examine assumptions about the role, importance and implementation of video information in such systems. Rather than focussing on novel technologies, we present evaluation data relevant to both the classes of real-time multimedia applications we should develop and their design and implementation. Evaluations of videoconferencing systems show that previous work has overestimated the importance of video at the expense of audio. This has strong implications for the implementation of bandwidth allocation and synchronization. Furthermore our recent studies of workplace interaction show that prior work has neglected another potentially vital function of visual information: in assessing the communication availability of others. In this new class of application, rather than providing a supplement to audio information, visual information is used to promote the opportunistic communications that are prevalent in face-to-face settings. We discuss early experiments with such connection applications and identify outstanding design and implementation issues. Finally we examine a different class of application 'video-as-data', where the video image is used to transmit information about the work objects themselves, rather than information about interactants.

    1999-11-01

    Coded digital video signals are considered to be one of the most difficult data types to transport due to their real-time requirements and high bit rate variability. In this study, the authors discuss the coding mechanisms incorporated by the major compression standards bodies, i.e., JPEG and MPEG, as well as more advanced coding mechanisms such as wavelet and fractal techniques. The relationship between the applications which use these coding schemes and their network requirements are the major focus of this study. Specifically, the authors relate network latency, channel transmission reliability, random access speed, buffering and network bandwidth with the various coding techniques as a function of the applications which use them. Such applications include High-Definition Television, Video Conferencing, Computer-Supported Collaborative Work (CSCW), and Medical Imaging.

    New medical schools have been opened in the eastern and southeastern regions of the country. They are also in great need of basic medical science teachers. However, due to security reasons over the past two decades, teachers from the established universities do not desire to travel to these medical schools for lectures. The objective of this study was to develop a synchronous classroom conferencing system to teach basic science courses between two general purpose technology enhanced classrooms of two different universities--Istanbul University (IU) and Istanbul and Harran University (HU), Urfa--located 1,500 miles apart in Turkey. I videostreamed the instructor, content from document camera, Power Point presentations at IU, and the students at both places, IU and HU. In addition, I synchronously broadcast two whiteboards by attaching two mimio devices to the two blackboards in the IU classroom to capture and convert everything written or drawn on them into broadcasting over the intranet. This technique is called "boardcasting," which allows users to stream ink and audio together over the Internet or intranet live. A total of 260 students at IU and 150 students at HU were involved. Off-campus HU students also have asynchronous access to the stored lecture video materials at any time. Midterm and final examinations were administered simultaneously using the same questions at both sites in two universities under the observation of the teaching faculty using the very same system. This system permitted interaction between the students in the class at IU and remote-campus students at HU and the instructor in real time. The instructors at IU were able to maintain a significant level of spontaneity in using their multimedia materials and electronic whiteboards. The mean midterm and final exam scores of students at both universities were similar. The system developed in this study can be used by the medical faculty at the main teaching hospitals to deliver their lectures in

    2007-10-11

    The Department of Laboratory Medicine at the University of California, San Francisco (UCSF) has been split into widely separated facilities, leading to much time being spent traveling between facilities for meetings. We installed an open-source AccessGrid multi-media-conferencing system using (largely) consumer-grade equipment, connecting 6 sites at 5 separate facilities. The system was accepted rapidly and enthusiastically, and was inexpensive compared to alternative approaches. Security was addressed by aspects of the AG software and by local network administrative practices. The chief obstacles to deployment arose from security restrictions imposed by multiple independent network administration regimes, requiring a drastically reduced list of network ports employed by AG components.

    2015-05-01

    Professionals in a variety of specialties use video-based review as a method of constant self-evaluation. We believe critical self-reflection will allow a surgical trainee to identify methods for improvement throughout residency and beyond. We have used 2 new popular technologies to evaluate their role in accomplishing the previously mentioned objectives. Our group investigated Google Glass and GoPro cameras. Medical students, residents, and faculty were invited to wear each of the devices during a scheduled operation. After the case, each participant was asked to comment on a number of features of the device including comfort, level of distraction/interference with operating, ease of video acquisition, and battery life. Software and hardware specifications were compiled and compared by the authors. A "proof-of-concept" was also performed using the video-conferencing abilities of Google Glass to perform a simulated flap check. The technical specifications of the 2 cameras favor GoPro over Google Glass. Glass records in 720p with 5-MP still shots, and the GoPro records in 1080p with 12-MP still shots. Our tests of battery life showed more than 2 hours of continuous video with GoPro, and less than 1 hour for Glass. Favorable features of Google Glass included comfort and relative ease of use; they could not comfortably wear loupes while operating, and would have preferred longer hands-free video recording. The GoPro was slightly more cumbersome and required a nonsterile team member to activate all pictures or video; however, loupes could be worn. Google Glass was successfully used in the hospital for a simulated flap check, with overall audio and video being transmitted--fine detail was lost, however. There are benefits and limitations to each of the devices tested. Google Glass is in its infancy and may gain a larger intraoperative role in the future. We plan to use Glass as a way for trainees to easily acquire intraoperative footage as a means to "review tape" and

    Video technology has been widely used in education especially in teaching and learning. However, the use of video technology for evaluation purpose especially in teaching practicum is extremely scarce and the benefits of video technology in teaching practicum evaluation have not yet been fully discovered. For that reason, this quantitative research aimed at identifying the perceptions of trainee teachers towards teaching practicum evaluation via video technology. A total of 260 students of Teacher Certification Programme (Program Pensiswazahan Guru - PPG) from the Faculty of Technical and Vocational Education (FPTV) of Universiti Tun Hussein Onn Malaysia (UTHM) had been randomly selected as respondents. A set of questionnaire was developed to assess the suitability, effectiveness and satisfaction of using video technology for teaching practicum. Conclusively, this research showed that the trainee teachers have positive perceptions in all three aspects related teaching practicum evaluation using video technology. Apart from that, no significant racial difference was found in the measured aspects. In addition, the trainee teachers also showed an understanding of the vast importance of teaching practicum evaluation via video. These research findings suggest that video technology can be a feasible and practical means of teaching practicum evaluation especially for distance learning program.

    2015-03-01

    As the effect of atmospheric particles scattering, the video image captured by outdoor surveillance system has low contrast and brightness, which directly affects the application value of the system. The traditional defogging technology is mostly studied by software for the defogging algorithms of the single frame image. Moreover, the algorithms have large computation and high time complexity. Then, the defogging technology of video image based on Digital Signal Processing (DSP) has the problem of complex peripheral circuit. It can't be realized in real-time processing, and it's hard to debug and upgrade. In this paper, with the improved dark channel prior algorithm, we propose a kind of defogging technology of video image based on Field Programmable Gate Array (FPGA). Compared to the traditional defogging methods, the video image with high resolution can be processed in real-time. Furthermore, the function modules of the system have been designed by hardware description language. At last, the results show that the defogging system based on FPGA can process the video image with minimum resolution of 640×480 in real-time. After defogging, the brightness and contrast of video image are improved effectively. Therefore, the defogging technology proposed in the paper has a great variety of applications including aviation, forest fire prevention, national security and other important surveillance.

    With NASA placing increased emphasis on transferring technology to outside industry, NASA researchers need to evaluate many aspects of their efforts in this regard. Often it may seem like too much self-promotion to many researchers. However, industry's use of video presentations in sales, advertising, public relations and training should be considered. Today, the most typical presentation at NASA is through the use of vu-graphs (overhead transparencies) which can be effective for text or static presentations. For full blown color and sound presentations, however, the best method is videotape. In fact, it is frequently more convenient due to its portability and the availability of viewing equipment. This talk describes techniques for creating a video presentation through the use of a combined researcher and video professional team.

    The objectives of conservation science and dissemination of its research create a paradox: Conservation is about preserving the environment, yet scientists spread this message at conferences with heavy carbon footprints. Ecology and conservation science depend on global knowledge exchange-getting the best science to the places it is most needed. However, conference attendance from developed countries typically outweighs that from developing countries that are biodiversity and conservation hotspots. If any branch of science should be trying to maximize participation while minimizing carbon emissions, it is conservation. Virtual conferencing is common in other disciplines, such as education and humanities, but it is surprisingly underused in ecology and conservation. Adopting virtual conferencing entails a number of challenges, including logistics and unified acceptance, which we argue can be overcome through planning and technology. We examined 4 conference models: a pure-virtual model and 3 hybrid hub-and-node models, where hubs stream content to local nodes. These models collectively aim to mitigate the logistical and administrative challenges of global knowledge transfer. Embracing virtual conferencing addresses 2 essential prerequisites of modern conferences: lowering carbon emissions and increasing accessibility for remote, time- and resource-poor researchers, particularly those from developing countries. © 2017 The Authors.

    From the past two decades the extreme evolution of the Internet has lead a massive rise in video technology and significantly video consumption over the Internet which inhabits the bulk of data traffic in general. Clearly, video consumes that so much data size on the World Wide Web, to reduce the burden on the Internet and deduction of bandwidth consume by video so that the user can easily access the video data.For this, many video codecs are developed such as HEVC/H.265 and V9. Although after seeing codec like this one gets a dilemma of which would be improved technology in the manner of rate distortion and the coding standard.This paper gives a solution about the difficulty for getting low delay in video compression and video application e.g. ad-hoc video conferencing/streaming or observation by surveillance. Also this paper describes the benchmark of HEVC and V9 technique of video compression on subjective oral estimations of High Definition video content, playback on web browsers. Moreover, this gives the experimental ideology of dividing the video file into several segments for compression and putting back together to improve the efficiency of video compression on the web as well as on the offline mode.

    While didactic conferences are an important component of residency training, delivering them efficiently is a challenge for many programs, especially when residents are located in multiple sites, as they are at Wayne State University School of Medicine in the Department of Family Medicine. Our residents find it difficult to travel from our hospitals or rotation sites to a centralized location for conferences. In order to overcome this barrier, we implemented distance learning and electronically delivered the conferences to the residents. We introduced an Internet-delivered, group-learning interactive conference model in which the lecturer is in one location with a group of residents and additional residents are in multiple locations. We launched the project in July 2001 using external company meeting services to schedule, coordinate, support, and archive the conferences. Equipment needed in each location consisted of a computer with an Internet connection, a telephone line, and a LCD projector (a computer monitor sufficed for small groups). We purposely chose simple distance-learning technology and used widely available equipment. Our e-conferencing had two components: (1) audio transmission via telephone connection and (2) visual transmission of PowerPoint presentations via the Internet. The telephone connection was open to all users, allowing residents to ask questions or make comments. Residents chose a conference location depending on geographic proximity to their rotation locations. Although we could accommodate up to 50 sites, we focused on a small number of locations in order to facilitate interaction among residents and faculty. Each conference session is archived and stored on the server for one week so those residents whose other residency-related responsibilities precluded attendance can view any conferences they have missed. E-conferencing proved to be an effective method of delivering didactics in our residency program. Its many advantages included

  6. Public Education and Outreach Through Full-Dome Video Technology

    Pollock, John

    2009-03-01

    My long-term goal is to enhance public understanding of complex systems that can be best demonstrated through richly detailed computer graphic animation displayed with full-dome video technology. My current focus is on health science advances that focus on regenerative medicine, which helps the body heal itself. Such topics facilitate science learning and health literacy. My team develops multi-media presentations that bring the scientific and medical advances to the public through immersive high-definition video animation. Implicit in treating the topics of regenerative medicine will be the need to address stem cell biology. The topics are clarified and presented from a platform of facts and balanced ethical consideration. The production process includes communicating scientific information about the excitement and importance of stem cell research. Principles of function are emphasized over specific facts or terminology by focusing on a limited, but fundamental set of concepts. To achieve this, visually rich, biologically accurate 3D computer graphic environments are created to illustrate the cells, tissues and organs of interest. A suite of films are produced, and evaluated in pre- post-surveys assessing attitudes, knowledge and learning. Each film uses engaging interactive demonstrations to illustrate biological functions, the things that go wrong due to disease and disability, and the remedy provided by regenerative medicine. While the images are rich and detailed, the language is accessible and appropriate to the audience. The digital, high-definition video is also re-edited for presentation in other ``flat screen'' formats, increasing our distribution potential. Show content is also presented in an interactive web space (www.sepa.duq.edu) with complementing teacher resource guides and student workbooks and companion video games.

    A HTTP based video transmission system has been built upon the p2p(peer to peer) network structure utilizing the Java technologies. This makes the video monitoring available to any host which has been connected to the World Wide Web in any method, including those hosts behind firewalls or in isolated sub-networking. In order to achieve this, a video source peer has been developed, together with the client video playback peer. The video source peer can respond to the video stream request in HTTP protocol. HTTP based pipe communication model is developed to speeding the transmission of video stream data, which has been encoded into fragments using the JPEG codec. To make the system feasible in conveying video streams between arbitrary peers on the web, a HTTP protocol based relay peer is implemented as well. This video monitoring system has been applied in a tele-robotic system as a visual feedback to the operator.

  15. A video event trigger for high frame rate, high resolution video technology

    Williams, Glenn L.

    1991-01-01

    When video replaces film the digitized video data accumulates very rapidly, leading to a difficult and costly data storage problem. One solution exists for cases when the video images represent continuously repetitive 'static scenes' containing negligible activity, occasionally interrupted by short events of interest. Minutes or hours of redundant video frames can be ignored, and not stored, until activity begins. A new, highly parallel digital state machine generates a digital trigger signal at the onset of a video event. High capacity random access memory storage coupled with newly available fuzzy logic devices permits the monitoring of a video image stream for long term or short term changes caused by spatial translation, dilation, appearance, disappearance, or color change in a video object. Pretrigger and post-trigger storage techniques are then adaptable for archiving the digital stream from only the significant video images.

    An overview of video coding is presented. The aim is not to give a technical summary of possible coding techniques, but to address subjects related to video compression in general and to the transmission of compressed video in more detail. Bit rate reduction is in general possible by removing redundant information; removing information the eye does not use anyway; and reducing the quality of the video. The codecs which are used for reducing the bit rate, can be divided into two groups: Constant Bit rate Codecs (CBC's), which keep the bit rate constant, but vary the video quality; and Variable Bit rate Codecs (VBC's), which keep the video quality constant by varying the bit rate. VBC's can be in general reach a higher video quality than CBC's using less bandwidth, but need a transmission system that allows the bandwidth of a connection to fluctuate in time. The current and the next generation of the PSTN does not allow this; ATM might. There are several factors which influence the quality of video: the bit error rate of the transmission channel, slip rate, packet loss rate/packet insertion rate, end-to-end delay, phase shift between voice and video, and bit rate. Based on the bit rate of the coded video, the following classification of coded video can be made: High Definition Television (HDTV); Broadcast Quality Television (BQTV); video conferencing; and video telephony. The properties of these classes are given. The video conferencing and video telephony equipment available now and in the next few years can be divided into three categories: conforming to 1984 CCITT standard for video conferencing; conforming to 1988 CCITT standard; and conforming to no standard.

    2017-01-01

    The popularity of video-assisted thoracic surgery (VATS) which increased worldwide due to the recent innovations in thoracic surgical technics, equipment, electronic devices that carry light and vision and high definition monitors. Uniportal VATS (UVATS) is disseminated widely, creating a drive to develop new techniques and instruments, including new graspers and special staplers with more angulation capacities. During the history of VATS, the classical 10 mm 0° or 30° rigid rod lens system, has been replaced by new thoracoscopes providing a variable angle technology and allowing 0° and 120° range of vision. Besides, the tip of these novel thoracoscopes can be positioned away from the operating side minimize fencing with other thoracoscopic instruments. The curved-tip stapler technology, and better designed endostaplers helped better dissection, precision of control, more secure staple lines. UVATS also contributed to the development of embryonic natural orifice transluminal endoscopic surgery. Three-dimensional VATS systems facilitated faster and more accurate grasping, suturing, and dissection of the tissues by restoring natural 3D vision and the perception of depth. Another innovation in VATS is the energy-based coagulative and tissue fusion technology which may be an alternative to endostaplers.

    2012-08-01

    The Global Operative Assessment of Laparoscopic Skill (GOALS) is one validated metric utilized to grade laparoscopic skills and has been utilized to score recorded operative videos. To facilitate easier viewing of these recorded videos, we are developing novel techniques to enable surgeons to view these videos. The objective of this study is to determine the feasibility of utilizing widespread current consumer-based technology to assist in distributing appropriate videos for objective evaluation. Videos from residents were recorded via a direct connection from the camera processor via an S-video output via a cable into a hub to connect to a standard laptop computer via a universal serial bus (USB) port. A standard consumer-based video editing program was utilized to capture the video and record in appropriate format. We utilized mp4 format, and depending on the size of the file, the videos were scaled down (compressed), their format changed (using a standard video editing program), or sliced into multiple videos. Standard available consumer-based programs were utilized to convert the video into a more appropriate format for handheld personal digital assistants. In addition, the videos were uploaded to a social networking website and video sharing websites. Recorded cases of laparoscopic cholecystectomy in a porcine model were utilized. Compression was required for all formats. All formats were accessed from home computers, work computers, and iPhones without difficulty. Qualitative analyses by four surgeons demonstrated appropriate quality to grade for these formats. Our preliminary results show promise that, utilizing consumer-based technology, videos can be easily distributed to surgeons to grade via GOALS via various methods. Easy accessibility may help make evaluation of resident videos less complicated and cumbersome.

    2016-03-01

    Full Text Available As audio visual communication technologies are installed in prisons, these spaces of incarceration are networked with courtrooms and other non-contiguous spaces, potentially facilitating a process of permeability. Jurisdictions around the world are embracing video conferencing and the technology is becoming a major interface for prisoners’ interactions with courts and legal advisers. In this paper, I draw on fieldwork interviews with prisoners from two correction centres in New South Wales, Australia, to understand their subjective and sensorial experiences of using video links as a portal to the outside world. These interviews raised many issues including audio permeability: a soundtrack of incarceration sometimes infiltrates into the prison video studio and then the remote courtroom, framing the prisoner in the context of their detention, intruding on legal process, and affecting prisoners’ comprehension and participation.

    This paper describes four state-of-the-art digital video cameras, which provide advanced features that benefit computer image enhancement, manipulation, and analysis. These cameras were designed to reduce the complexity of imaging systems while increasing the accuracy, dynamic range, and detail enhancement of product inspections. Two cameras utilize progressive scan CCD sensors enabling the capture of high- resolution image of moving objects without the need for strobe lights or mechanical shutters. The second progressive scan camera has an unusually high resolution of 1280 by 1024 and a choice of serial or parallel digital interface for data and control. The other two cameras incorporate digital signal processing (DSP) technology for improved dynamic range, more accurate determination of color, white balance stability, and enhanced contrast of part features against the background. Successful applications and future product development trends are discussed. A brief description of analog and digital image capture devices will address the most common questions regarding interface requirements within a typical machine vision system overview.

    Video transmission over variable-bandwidth networks requires instantaneous bit-rate adaptation at the server site to provide an acceptable decoding quality. For this purpose, recent developments in video coding aim at providing a fully embedded bit-stream with seamless adaptation capabilities in bit-rate, frame-rate and resolution. A new promising technology in this context is wavelet-based video coding. Wavelets have already demonstrated their potential for quality and resolution scalability in still-image coding. This led to the investigation of various schemes for the compression of video, exploiting similar principles to generate embedded bit-streams. In this paper we present scalable wavelet-based video-coding technology with competitive rate-distortion behavior compared to standardized non-scalable technology.

    The goal of telementoring is to recreate face-to-face encounters with a digital presence. Open-surgery telementoring is limited by lack of surgeon's point-of-view cameras. Google Glass is a wearable computer that looks like a pair of glasses but is equipped with wireless connectivity, a camera, and viewing screen for video conferencing. This study aimed to assess the safety of using Google Glass by assessing the video quality of a telementoring session. Thirty-four (n = 34) surgeons at a single institution were surveyed and blindly compared via video captured with Google Glass versus an Apple iPhone 5 during the open cholecystectomy portion of a Whipple. Surgeons were asked to evaluate the quality of the video and its adequacy for safe use in telementoring. Thirty-four of 107 invited surgical attendings (32%) responded to the anonymous survey. A total of 50% rated the Google Glass video as fair with the other 50% rating it as bad to poor. A total of 52.9% of respondents rated the Apple iPhone video as good. A significantly greater proportion of respondents felt Google Glass video quality was inadequate for telementoring versus the Apple iPhone's (82.4 vs 26.5%, p Google Glass provides a great breadth of functionality as a wearable device with two-way communication capabilities, current hardware limitations prevent its use as a telementoring device in surgery as the video quality is inadequate for safe telementoring. As the device is still in initial phases of development, future iterations or competitor devices may provide a better telementoring application for wearable devices.

    This study examines the role of video technology in the development of cooking skills. The study explored the views of 141 female participants on whether video technology can promote confidence in learning new cooking skills to assist in meal preparation. Prior to each focus group participants took part in a cooking experiment to assess the most effective method of learning for low-skilled cooks across four experimental conditions (recipe card only; recipe card plus video demonstration; recipe card plus video demonstration conducted in segmented stages; and recipe card plus video demonstration whereby participants freely accessed video demonstrations as and when needed). Focus group findings revealed that video technology was perceived to assist learning in the cooking process in the following ways: (1) improved comprehension of the cooking process; (2) real-time reassurance in the cooking process; (3) assisting the acquisition of new cooking skills; and (4) enhancing the enjoyment of the cooking process. These findings display the potential for video technology to promote motivation and confidence as well as enhancing cooking skills among low-skilled individuals wishing to cook from scratch using fresh ingredients.

    Full Text Available ABSTRACT This paper reports on the trial of web conferencing software conducted at a regional Australian university with a significant distance population. The paper shares preliminary findings, the views of participants and recommendations for future activity. To design and conduct the trial, an action research method was chosen because it is participative and grounded in experience, reflecting the context and objectives of the trial. In the first phase of the trial, students in postgraduate Education courses were linked across the globe to participate in interactive and collaborative conference activity and to communicate via audio, text, and video and shared whiteboard. Mathematical problem-solving was carried out collaboratively in an undergraduate course using tablet PCs. This was followed by phase 2, a university-wide trial across disciplines. Preliminary findings indicate that web conferencing software enables teachers and students at the university to engage actively across diverse locations, supporting a student-centred approach and greater flexibility in terms of where, when and how students learn. From these findings, the authors have made some initial recommendations to university management on the adoption of web conferencing to support learning and teaching.

    With the prevalence of video recordings from smart phones, dash cams, body cams, and conventional surveillance cameras, privacy protection has become a major concern, especially in light of legislation such as the Freedom of Information Act. Video redaction is used to obfuscate sensitive and personally identifiable information. Today's typical workflow involves simple detection, tracking, and manual intervention. Automated methods rely on accurate detection mechanisms being paired with robust tracking methods across the video sequence to ensure the redaction of all sensitive information while minimizing spurious obfuscations. Recent studies have explored the use of convolution neural networks and recurrent neural networks for object detection and tracking. The present paper reviews the redaction problem and compares a few state-of-the-art detection, tracking, and obfuscation methods as they relate to redaction. The comparison introduces an evaluation metric that is specific to video redaction performance. The metric can be evaluated in a manner that allows balancing the penalty for false negatives and false positives according to the needs of particular application, thereby assisting in the selection of component methods and their associated hyperparameters such that the redacted video has fewer frames that require manual review.

    Finkelstein, Stanley M.

    2014-01-01

    Abstract Background: Incorporating telehealth into outpatient care delivery supports management of consumer health between clinic visits. Task–technology fit is a framework for understanding how technology helps and/or hinders a person during work processes. Evaluating the task–technology fit of video telehealth for personnel working in a pediatric outpatient clinic and providing care between clinic visits ensures the information provided matches the information needed to support work processes. Materials and Methods: The workflow of advanced practice registered nurse (APRN) care coordination provided via telephone and video telehealth was described and measured using a mixed-methods workflow analysis protocol that incorporated cognitive ethnography and time–motion study. Qualitative and quantitative results were merged and analyzed within the task–technology fit framework to determine the workflow fit of video telehealth for APRN care coordination. Results: Incorporating video telehealth into APRN care coordination workflow provided visual information unavailable during telephone interactions. Despite additional tasks and interactions needed to obtain the visual information, APRN workflow efficiency, as measured by time, was not significantly changed. Analyzed within the task–technology fit framework, the increased visual information afforded by video telehealth supported the assessment and diagnostic information needs of the APRN. Conclusions: Telehealth must provide the right information to the right clinician at the right time. Evaluating task–technology fit using a mixed-methods protocol ensured rigorous analysis of fit within work processes and identified workflows that benefit most from the technology. PMID:24841219

    A large telemedicine project is now under development in Moscow. The general task of the project is to link oncology research centres and hospitals meeting the project profile, and to provide on-line (using real-time video conferences) and off-line (via distributed database of medical information) information exchange. There was no existing technology available for use at the project's base which was ready to meet all requirements, so we are using specially created technology for video networks (DiViSy V.97). We suppose this technology to be more applicable for use in telemedicine networks than are business video conference technologies and classical Internet/Intranet technologies. We affirm in our conclusion that now is the time for developing special telemedicine standards, recommendations of compatibility, etc., and that we are ready to take part in this process.

    Cardiac patients may undergo a range of diagnostic examinations including angiography, echocardiography, nuclear medicine, x-ray, ECG and blood pressure measurement. Cine angiograms are reviewed at cardiac case conferences. Other data types are not typically exhibited due to the incompatibility of display devices. The aim of this study was to evaluate a workstation developed for multimodality reporting in cardiac case conferencing. A PC based system was developed as part of an EU project AMIE enabling all patient data to be viewed and manipulated on a large screen display using a high resolution video projector. The digital data was acquired using a variety of methods compatible with the systems involved. A technical evaluation of the projected imagery was performed by the grading of phantom test objects. A limited clinical evaluation was also performed whereby a panel of 10 consultant radiologists and cardiologists reported on angiography and x-ray images from 50 patients. Several months later the original data sets were reported and the result compared. Results of the clinical and technical evaluations indicate that the systems is satisfactory for the primary diagnosis of all data types with the exception of x-ray. The projected x-ray imagery is satisfactory for reference and teaching purposes.

    Success in the future ability to conduct global ocean research relies on our strategies to teach and train the next generation of ocean scientists. The mission of the Exploration and Remote Instrumentation by Students (ERIS) program at the University of Washington is to enhance undergraduate learning in the design and build process of advanced technologies. The ERIS program introduces the science of applied technology in oceanography through a series of courses that link the design, build, and maintenance of a student implemented underwater cabled observatory. We present a suggested template for a production method of how-to videos focused on capturing and communicating the design and build experience in ocean technology makerspaces. The application of this production method of videos produced by students, for students, creates structured learning opportunities and becomes an archive of online resources for future ocean technologists. Furthermore, video documentation enables students to link their participation in active learning experiences with skills in ocean science, technology and communication.

    We conducted two studies to test the validity, reliability, feasibility and acceptability of using video chat technology to quantify dietary and pill-taking (i.e. supplement and medication) adherence. In study 1, we investigated whether video chat technology can accurately quantify adherence to dietary and pill-taking interventions. Mock study participants ate food items and swallowed pills, while performing randomised scripted 'cheating' behaviours to mimic non-adherence. Monitoring was conducted in a cross-over design, with two monitors watching in-person and two watching remotely by Skype on a smartphone. For study 2, a twenty-two-item online survey was sent to a listserv with more than 20 000 unique email addresses of past and present study participants to assess the feasibility and acceptability of the technology. For the dietary adherence tests, monitors detected 86 % of non-adherent events (sensitivity) in-person v. 78 % of events via video chat monitoring (P=0·12), with comparable inter-rater agreement (0·88 v. 0·85; P=0·62). However, for pill-taking, non-adherence trended towards being more easily detected in-person than by video chat (77 v. 60 %; P=0·08), with non-significantly higher inter-rater agreement (0·85 v. 0·69; P=0·21). Survey results from study 2 (n 1076 respondents; ≥5 % response rate) indicated that 86·4 % of study participants had video chatting hardware, 73·3 % were comfortable using the technology and 79·8 % were willing to use it for clinical research. Given the capability of video chat technology to reduce participant burden and outperform other adherence monitoring methods such as dietary self-report and pill counts, video chatting is a novel and promising platform to quantify dietary and pill-taking adherence.

    Diverse products either based solely on or incorporating Shape Memory Alloys (SMA) have and are being made in a wide range of industries, and IP is being captured. Why then compared to SE (superelastic) Nitinol, and especially conventional technology, do so few ideas reach production? This presentation delves deeply into this topic in reaching the final assessment that SMA actuators are indeed now a viable practical technology. The presentation begins with an introduction to and description of the fundamental basis of SMA actuator technology. Examples of multiple commercially available geometric forms of SMA actuators are given and the functionalities that they provide are described. This is followed by examples of multiple commercial products incorporating such SMA actuators. Given that there are literally millions of commercial products incorporating conventional actuator technologies, indications are given as to why there are their less than 1000 that utilize SMA. Experience based challenges to the commercial use of SMA actuators are described. Besides having to compete with existing non-SMA technology which is quite mature additional challenges that are unique to SM actuators are indicated these including a wider than expected set of technical engineering problems and challenges and that a broader scope of dynamics is required.

  8. Optical video projection using laser beam scanning technology

    Science.gov (United States)

    Clynick, Tony J.

    1993-12-01

    Various techniques are currently used to project video images. One of these, described in a previous paper by the author, operates by mechanical scanning of a laser beam with acousto- optic modulation, and has been proven suitable for high definition television and computer display scan rates by use of novel electronic and optical compensation methods. The requirement for improved image intensity with greater efficiency has led to a re-appraisal of the selection of the light source and the relationship between the light source, the form of the modulator, and the method of scanning. The electrical input to visible radiation output ratio of the Argon-ion lasers currently used in the projector shows efficiency to be as low as 0.001%, a factor limiting the commercial exploitation of the projector. Recent developments in acousto- optics can be applied to the projector's optical system allowing alternative light sources to be used. These help to reduce the complexity of both the optical and signal processing stages as well as improve efficiency.

    Discharge anticoagulation counseling is important for ensuring patient comprehension and optimizing clinical outcomes. As pharmacy resources become increasingly limited, the impact of informational videos on the counseling process becomes more relevant. To evaluate differences in pharmacist time spent counseling and patient comprehension (measured by the Oral Anticoagulation Knowledge [OAK] test) between informational videos and traditional face-to-face (oral) counseling. This prospective, open, parallel-group study at an academic medical center randomized 40 individuals-17 warfarin-naïve ("New Start") and 23 with prior warfarin use ("Restart")-to receive warfarin discharge education by video or face-to-face counseling. "Teach-back" questions were used in both groups. Although overall pharmacist time was reduced in the video counseling group (P counseling method (P = 0.012) suggests the difference between counseling methods was smaller in New Start participants. Following adjustment, mean total time was reduced 8.71 (95% CI = 5.15-12.26) minutes (adjusted P counseling. Postcounseling OAK test scores did not differ. Age, gender, socioeconomic status, and years of education were not predictive of total time or OAK test score. Use of informational videos coupled with teach-back questions significantly reduced pharmacist time spent on anticoagulation counseling without compromising short-term patient comprehension, primarily in patients with prior warfarin use. Study results demonstrate that video technology provides an efficient method of anticoagulation counseling while achieving similar comprehension. © The Author(s) 2015.

    Full Text Available A key enabling technology for the proliferation of multimedia PC's is the availability of fast video codecs, which are the basic building blocks of many new multimedia applications. Since most industrial video coding standards (e.g., MPEG1, MPEG2, H.261, H.263 only specify the decoder syntax, there are a lot of rooms for optimization in a practical implementation. When considering a specific hardware platform like the PC, the algorithmic optimization must be considered in tandem with the architecture of the PC. Specifically, an algorithm that is optimal in the sense of number of operations needed may not be the fastest implementation on the PC. This is because special instructions are available which can perform several operations at once under special circumstances. In this work, we describe a fast implementation of H.263 video encoder for the Pentium processor with MMX technology. The described codec is adopted for video mail and video phone softwares used in IBM ThinkPad.

    Technology has the potential to impact cognition in many ways. Here we contrast two forms of technology usage: 1) media multitasking (i.e., the simultaneous consumption of multiple streams of media, such a texting while watching TV) and 2) playing action video games (a particular sub-type of video game). Previous work has outlined an association between high levels of media multitasking and specific deficits in handling distracting information, while playing action video games has been associated with enhanced attentional control. As these two factors are linked with reasonably opposing effects, failing to take them jointly into account may result in inappropriate conclusions as to the impact of technology use on attention. Across four experiments (AX-CPT, N-back, Task-switching and Filter task), testing different aspects of attention and cognition, we show that heavy media multitaskers perform worse than light media multitaskers. Contrary to previous reports though, the performance deficit was not specifically tied to distractors, but was instead more global in nature. Interestingly, participants with intermediate levels of media multitasking occasionally performed better than both light and heavy media multitaskers suggesting that the effects of increasing media multitasking are not monotonic. Action video game players, as expected, outperformed non-video game players on all tasks. However, surprisingly this was true only for participants with intermediate levels of media multitasking, suggesting that playing action video games does not protect against the deleterious effect of heavy media multitasking. Taken together this study shows that media consumption can have complex and counter-intuitive effects on attentional control. PMID:26474982

    Full Text Available Recording lectures using video lecture capture software and making them available for students to watch anytime, from anywhere, has become a common practice in many universities across many disciplines. The software has become increasingly easy to use and is commonly provided and maintained by higher education institutions. Several studies have reported that students use lecture capture to enhance their learning and study for assessments, as well as to catch up on material they miss when they cannot attend class due to extenuating circumstances. Furthermore, students with disabilities and students from non-English Speaking Backgrounds (NESB may benefit from being able to watch the video lecture captures at their own pace. Yet, the effect of this technology on class attendance remains a controversial topic and largely unexplored in undergraduate microbiology education. Here, we show that when video lecture captures were available in our large enrollment general microbiology courses, attendance did not decrease. In fact, the majority of students reported that having the videos available did not encourage them to skip class, but rather they used them as a study tool. When we surveyed NESB students and nontraditional students about their attitudes toward this technology, they found it helpful for their learning and for keeping up with the material.

    The purpose of this pilot study was to examine if tablet technology with accompanying instructional videos enhanced the teaching and learning outcomes in a preclinical dental laboratory setting. Two procedures deemed most challenging in Operative Dentistry II were chosen for the development of instructional videos. A random sample of thirty students was chosen to participate in the pilot. Comparison of faculty evaluations of the procedures between the experimental (tablet) and control (no tablet) groups resulted in no significant differences; however, there was a trend toward fewer failures in the experimental group. Examination of the ability to accurately self-assess was compared by exploring correlations between faculty and student evaluations. While correlations were stronger in the experimental group, the control group had significant correlations for all three procedures, while the experimental group had significant correlations on only two of the procedures. Students strongly perceived that the tablets and videos helped them perform better and more accurately self-assess their work products. Students did not support requiring that they purchase/obtain a specific brand of technology. As a result of this pilot study, further development of ideal and non-ideal videos are in progress, and the school will be implementing a "Bring Your Own Device" policy with incoming students.

    Full Text Available Owing to the growth of high performance network technologies, multimedia applications over the Internet are increasing exponentially. Applications like video conferencing, video-on-demand, and pay-per-view depend upon encryption algorithms for providing confidentiality. Video communication is characterized by distinct features such as large volume, high redundancy between adjacent frames, video codec compliance, syntax compliance, and application specific requirements. Naive approaches for video encryption encrypt the entire video stream with conventional text based cryptographic algorithms. Although naive approaches are the most secure for video encryption, the computational cost associated with them is very high. This research work aims at enhancing the speed of naive approaches through chaos based S-box design. Chaotic equations are popularly known for randomness, extreme sensitivity to initial conditions, and ergodicity. The proposed methodology employs two-dimensional discrete Henon map for (i generation of dynamic and key-dependent S-box that could be integrated with symmetric algorithms like Blowfish and Data Encryption Standard (DES and (ii generation of one-time keys for simple substitution ciphers. The proposed design is tested for randomness, nonlinearity, avalanche effect, bit independence criterion, and key sensitivity. Experimental results confirm that chaos based S-box design and key generation significantly reduce the computational cost of video encryption with no compromise in security.

    The US health care system has been slow to adopt Internet, mobile, and video technologies, which have the capability to engage patients in their own care, increase patients' access to providers, and possibly improve the quality of care while reducing costs. Nevertheless, there are some pockets of progress, including Kaiser Permanente Northern California (KPNC). In 2008 KPNC implemented an inpatient and ambulatory care electronic health record system for its 3.4 million members and developed a suite of patient-friendly Internet, mobile, and video tools. KPNC has achieved many successes. For example, the number of virtual "visits" grew from 4.1 million in 2008 to an estimated 10.5 million in 2013. This article describes KPNC's experience with Internet, mobile, and video technologies and the obstacles faced by other health care providers interested in embracing them. The obstacles include the predominant fee-for-service payment model, which does not reimburse for virtual visits; the considerable investment needed to deploy these technologies; and physician buy-in.

    The aim of our study was to determine if there is a role for manipulation of g force thresholds acquired via micro-technology for accurately detecting collisions in rugby union. In total, 36 players were recruited from an elite Guinness Pro12 rugby union team. Player movement profiles and collisions were acquired via individual global positioning system (GPS) micro-technology units. Players were assigned to a sub-category of positions in order to determine positional collision demands. The coding of collisions by micro-technology at g force thresholds between 2 and 5.5 g (0.5 g increments) was compared with collision coding by an expert video analyst using Bland-Altman assessments. The most appropriate g force threshold (smallest mean difference compared with video analyst coding) was lower for all forwards positions (2.5 g) than for all backs positions (3.5 g). The Bland-Altman 95% limits of agreement indicated that there may be a substantial over- or underestimation of collisions coded via GPS micro-technology when using expert video analyst coding as the reference comparator. The manipulation of the g force thresholds applied to data acquired by GPS micro-technology units based on incremental thresholds of 0.5 g does not provide a reliable tool for the accurate coding of collisions in rugby union. Future research should aim to investigate smaller g force threshold increments and determine the events that cause coding of false positives.

    Aging services technologies (ASTs), health technology that meets the needs of seniors, are being underutilized due to a lack of awareness. This study evaluated a video-based educational program to increase AST awareness. Two hundred and thirty-one older adults completed AST measures pre- and post-program. Participants endorsed significantly improved AST knowledge and attitude and a lower level of perceived stigma post-program. Hierarchical regression analyses showed that a greater reduction in stigma post-program and a higher number of physical/cognitive needs supported by ASTs at baseline were significant predictors of a greater increase in expressed intention to use ASTs following the video program. Furthermore, individuals living in their own homes, with a lower level of education, fewer physical and/or cognitive needs supported by ASTs at baseline, and greater functional limitations were found to be more likely to report a significant reduction in perceived stigma post-program. Four-week follow-up data from 75 individuals showed stable program gains. Program feedback was positive. The current findings provide support for the utility of the AST videos. The educational materials used in this study can be used clinically or for public health education to increase awareness and adoption of ASTs. Copyright © 2017 Elsevier B.V. All rights reserved.

    In the setting of increasingly complex medical therapies and limited physician resources, the recent emergence of 'smart' technology offers tremendous potential for improved logistics, efficiency, and communication between medical team members. In an effort to harness these capabilities, we sought to evaluate the utility of this technology in surgical practice through the employment of a wearable camera device during cardiothoracic organ recovery. A single procurement surgeon was trained for use of an Explorer Edition Google Glass (Google Inc., Mountain View, CA) during the recovery process. Live video feed of each procedure was securely broadcast to allow for members of the home transplant team to remotely participate in organ assessment. Primary outcomes involved demonstration of technological feasibility and validation of quality assurance through group assessment. The device was employed for the recovery of four organs: a right single lung, a left single lung, and two bilateral lung harvests. Live video of the visualization process was remotely accessed by the home transplant team, and supplemented final verification of organ quality. In each case, the organs were accepted for transplant without disruption of standard procurement protocols. Media files generated during the procedures were stored in a secure drive for future documentation, evaluation, and education purposes without preservation of patient identifiers. Live video streaming can improve quality assurance measures by allowing off-site members of the transplant team to participate in the final assessment of donor organ quality. While further studies are needed, this project suggests that the application of mobile 'smart' technology offers not just immediate value, but the potential to transform our approach to the practice of medicine.

    Little is known about Millennial nursing students' attitudes toward computer games and new media in nursing education and whether these attitudes differ between undergraduates and graduates. This study elicited nursing students' experience with computer games and new media, their attitudes toward various instructional styles and methods, and the role of computer games and new media technologies in nursing education. We e-mailed all nursing students enrolled in two universities to invite their participation in an anonymous cross-sectional online survey. The survey collected demographic data and participants' experience with and attitudes toward video gaming and multi-player online health care simulations. We used descriptive statistics and logistic regression to compare the differences between undergraduates and graduates. Two hundred eighteen nursing students participated. Many of the nursing students support using new media technologies in nursing education. Nurse educators should identify areas suitable for new media integration and further evaluate the effectiveness of these technologies. Copyright 2011, SLACK Incorporated.

    2004-04-01

    Full Text Available In this paper, we suggest that case-based resources, which are used for assisting cognition during problem solving, can be structured around the work of narratives in social cultural psychology. Theories and other research methods have proposed structures within narratives and stories which may be useful to the design of case-based resources. Moreover, embedded within cases are stories which are contextually rich, supporting the epistemological groundings of situated cognition. Therefore the purposes of this paper are to discuss possible frameworks of case-stories; derive design principles as to “what” constitutes a good case story or narrative; and suggest how technology can support story-based learning. We adopt video-based Computer-Supported Collaborative Learning (CSCL technology to support problem solving with case-stories learning scenarios. Our hypothesis in this paper is that well-designed case-based resources are able to aid in the cognitive processes undergirding problem solving and meaning making. We also suggest the use of an emerging video-based collaborative learning technology to support such an instructional strategy.

    Visual information uptake is a fundamental element of sports involving interceptive tasks. Several methodologies, like video and methods based on virtual environments, are currently employed to analyze visual perception during sport situations. Both techniques have advantages and drawbacks. The goal of this study is to determine which of these technologies may be preferentially used to analyze visual information uptake during a sport situation. To this aim, we compared a handball goalkeeper's performance using two standardized methodologies: video clip and virtual environment. We examined this performance for two response tasks: an uncoupled task (goalkeepers show where the ball ends) and a coupled task (goalkeepers try to intercept the virtual ball). Variables investigated in this study were percentage of correct zones, percentage of correct responses, radial error and response time. The results showed that handball goalkeepers were more effective, more accurate and started to intercept earlier when facing a virtual handball thrower than when facing the video clip. These findings suggested that the analysis of visual information uptake for handball goalkeepers was better performed by using a 'virtual reality'-based methodology. Technical and methodological aspects of these findings are discussed further. Copyright © 2014 Elsevier B.V. All rights reserved.

  17. Measurement of the Dynamic Displacements of Railway Bridges Using Video Technology

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This article describes the development of a non-contact dynamic displacement measurement system for railway bridges based on video technology. The system, consisting of a high speed video camera, an optical lens, lighting lamps and a precision target, can perform measurements with high precision for distances from the camera to the target up to 25 m, with acquisition frame rates ranging from 64 fps to 500 fps, and be articulated with other measurement systems, which promotes its integration in structural health monitoring systems. The system’s performance was evaluated based on two tests, one in the laboratory and other on the field. The laboratory test evaluated the performance of the system in measuring the displacement of a steel beam, subjected to a point load applied dynamically, for distances from the camera to the target between 3 m and 15 m. The field test allowed evaluating the system’s performance in the dynamic measurement of the displacement of a point on the deck of a railway bridge, induced by passing trains at speeds between 160 km/h and 180 km/h, for distances from the camera to the target up to 25 m. The results of both tests show a very good agreement between the displacement measurement obtained with the video system and with a LVDT.

    The application of technologies, such as video gaming and social media for rehabilitation, is garnering interest in the medical field. However, little research has examined clinicians' perspectives regarding technology adoption by their clients. The objective of our study was to explore therapists' perceptions of how young people and adults with hemiplegia use gaming and social media technologies in daily life and in rehabilitation, and to identify barriers to using these technologies in rehabilitation. We conducted two focus groups comprised of ten occupational therapists/physiotherapists who provide neurorehabilitation to individuals with hemiplegia secondary to stroke or cerebral palsy. Data was analyzed using inductive thematic analysis. The diffusion of innovations theory provided a framework to interpret emerging themes. Therapists were using technology in a limited capacity. They identified barriers to using social media and gaming technology with their clients, including a lack of age appropriateness, privacy issues with social media, limited transfer of training, and a lack of accessibility of current systems. Therapists also questioned their role in the context of technology-based interventions. The opportunity for social interaction was perceived as a major benefit of integrated gaming and social media. This study reveals the complexities associated with adopting new technologies in clinical practice, including the need to consider both client and clinician factors. Despite reporting several challenges with applying gaming and social media technology with clinical populations, therapists identified opportunities for increased social interactions and were willing to help shape the development of an upper limb training system that could more readily meet the needs of clients with hemiplegia. By considering the needs of both therapists and clients, technology developers may increase the likelihood that clinicians will adopt innovative technologies.

We explored the use and potential value of an asynchronous, near-real time protocol-which avoids transmission issues associated with real-time applications-for recording, uploading, and viewing of high-definition (HD) visual media in the emergency department (ED) to facilitate remote surgical consults. Study Design First-responder physician assistants captured pertinent aspects of the physical examination and diagnostic imaging using Google Glass' HD video or high-resolution photographs. This visual media were then securely uploaded to the study website. The surgical consultation then proceeded over the phone in the usual fashion and a clinical decision was made. The surgeon then accessed the study website to review the uploaded video. This was followed by a questionnaire regarding how the additional data impacted the consultation. Results The management plan changed in 24% (11) of cases after surgeons viewed the video. Five of these plans involved decision making regarding operative intervention. Although surgeons were generally confident in their initial management plan, confidence scores increased further in 44% (20) of cases. In addition, we surveyed 276 ED patients on their opinions regarding concerning the practice of health care providers wearing and using recording devices in the ED. The survey results revealed that the majority of patients are amenable to the addition of wearable technology with video functionality to their care. Conclusions This study demonstrates the potential value of a medically dedicated, hands-free, HD recording device with internet connectivity in facilitating remote surgical consultation. © The Author(s) 2016.

    The present study aimed to integrate findings from technology acceptance research with research on applicant reactions to new technology for the emerging selection procedure of asynchronous video interviewing. One hundred six volunteers experienced asynchronous video interviewing and filled out several questionnaires including one on the applicants’ personalities. In line with previous technology acceptance research, the data revealed that perceived usefulness and perceived ease of use predicted attitudes toward asynchronous video interviewing. Furthermore, openness revealed to moderate the relation between perceived usefulness and attitudes toward this particular selection technology. No significant effects emerged for computer self-efficacy, job interview self-efficacy, extraversion, neuroticism, and conscientiousness. Theoretical and practical implications are discussed.

    Full Text Available The video games industry develops ever more advanced technologies to improve rendering, image quality, ergonomics and user experience of their creations providing very simple to use tools to design new games. In the molecular sciences, only a small number of experts with specialized know-how are able to design interactive visualization applications, typically static computer programs that cannot easily be modified. Are there lessons to be learned from video games? Could their technology help us explore new molecular graphics ideas and render graphics developments accessible to non-specialists? This approach points to an extension of open computer programs, not only providing access to the source code, but also delivering an easily modifiable and extensible scientific research tool. In this work, we will explore these questions using the Unity3D game engine to develop and prototype a biological network and molecular visualization application for subsequent use in research or education. We have compared several routines to represent spheres and links between them, using either built-in Unity3D features or our own implementation. These developments resulted in a stand-alone viewer capable of displaying molecular structures, surfaces, animated electrostatic field lines and biological networks with powerful, artistic and illustrative rendering methods. We consider this work as a proof of principle demonstrating that the functionalities of classical viewers and more advanced novel features could be implemented in substantially less time and with less development effort.

    This study used the actual laryngeal video stroboscope videos taken by physicians in clinical practice as the samples for experimental analysis. The samples were dynamic vocal fold videos. Image processing technology was used to automatically capture the image of the largest glottal area from the video to obtain the physiological data of the vocal folds. In this study, an automatic vocal fold disease identification system was designed, which can obtain the physiological parameters for normal vocal folds, vocal paralysis and vocal nodules from image processing according to the pathological features. The decision tree algorithm was used as the classifier of the vocal fold diseases. The identification rate was 92.6%, and the identification rate with an image recognition improvement processing procedure after classification can be improved to 98.7%. Hence, the proposed system has value in clinical practices. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Wang, Xiaohui; Goh, Dion Hoe-Lian

    2017-11-01

    The current study systematically reviews and summarizes the existing literature of game acceptance, identifies the core determinants, and evaluates the strength of the relationships in the extended technology acceptance model. Moreover, this study segments video games into two categories: hedonic and utilitarian and examines player acceptance of these two types separately. Through a meta-analysis of 50 articles, we find that perceived ease of use (PEOU), perceived usefulness (PU), and perceived enjoyment (PE) significantly associate with attitude and behavioral intention. PE is the dominant predictor of hedonic game acceptance, while PEOU and PU are the main determinants of utilitarian game acceptance. Furthermore, we find that respondent type and game platform are significant moderators. Findings of this study provide critical insights into the phenomenon of game acceptance and suggest directions for future research.

  13. Very low bit rate video coding standards

    Zhang, Ya-Qin

    1995-04-01

    Very low bit rate video coding has received considerable attention in academia and industry in terms of both coding algorithms and standards activities. In addition to the earlier ITU-T efforts on H.320 standardization for video conferencing from 64 kbps to 1.544 Mbps in ISDN environment, the ITU-T/SG15 has formed an expert group on low bit coding (LBC) for visual telephone below 64 kbps. The ITU-T/SG15/LBC work consists of two phases: the near-term and long-term. The near-term standard H.32P/N, based on existing compression technologies, mainly addresses the issues related to visual telephony at below 28.8 kbps, the V.34 modem rate used in the existing Public Switched Telephone Network (PSTN). H.32P/N will be technically frozen in January '95. The long-term standard H.32P/L, relying on fundamentally new compression technologies with much improved performance, will address video telephony in both PSTN and mobile environment. The ISO/SG29/WG11, after its highly visible and successful MPEG 1/2 work, is starting to focus on the next- generation audiovisual multimedia coding standard MPEG 4. With the recent change of direction, MPEG 4 intends to provide an audio visual coding standard allowing for interactivity, high compression, and/or universal accessibility, with high degree of flexibility and extensibility. This paper briefly summarizes these on-going standards activities undertaken by ITU-T/LBC and ISO/MPEG 4 as of December 1994.

  14. The design, implementation and evaluation of mass conferencing

    Directory of Open Access Journals (Sweden)

    Karl Donert

    1998-12-01

    Full Text Available The development of the PC has opened up many new perspectives in the use of technology for distance learning. Broadband, high-speed telecommunications now make it possible to access, transmit and receive sound, still images, video and other data. This application is normally referred to as videoconferencing (Woodruff and Mosby, 1996. It provides the capability to connect two or more parties separated by distance by means of audio, video and data and allows opportunities for real-time interaction. It is often used by groups of people who gather in a specific setting to communicate with other groups of people who are unable physically to be there. However, the term videoconferencing can be applied to a wide range of situations, such as individual-to-individual discussion and video-lecturing. Lopez and Woodruff (1996 identify four videoconferencing formats: the interview, the virtual meeting, the virtual field trip and the lecture. They state that the least productive of these is normally the lecture which, they suggest, does not promote dialogue or interaction: a lecture is as a one-way process where intellectual resources are transmitted, and as a learning environment does not usually provide opportunities for students to interact with tutors or between themselves. They are unlikely to establish any form of dialogue or to use their own thought processes (King and Honeybone, 1997. Whilst cost-effective in traditional terms, the lecture forum can be a shallow and relatively ineffective learning experience.

    Teleteaching of endoscopy has been limited by the exorbitant cost and time inherent in high-quality digital endoscopy video transmission. The Digital Video Transport System (DVTS) transmitted over advanced networks, such as Internet2 and the Asia-Pacific Advanced Network (APAN), provides a unique infrastructure for sharing uncompressed digital videos of endoscopy. This may allow high-quality, real-time, international training of diagnostic and therapeutic endoscopy techniques at a low cost. To test the proof of concept of long-distance teaching through live, interactive, high-resolution video transmission by using advanced networks and the DVTS. We used teleteaching of image-enhanced endoscopy techniques as a model. Prospective multicenter pilot study. Trainees, faculty, and staff at 3 international endoscopy units. An image-enhanced endoscopy video lecture with advanced-network technologies. We compared image-based prelecture and postlecture test scores and secondarily assessed technical feasibility and quality. The DVTS transmitted over advanced networks successfully transmitted uncompressed, high-resolution, digital lectures with endoscopic video (digital video format 720 x 480 pixels). Postsession scores improved. Participants highly rated the technical and informational quality. The majority reported a definite interest in participating in future sessions, with a mean rating (out of 5 [scale 1-5]) of 4.7 +/- 0.5. Pilot study with a limited number of participants and sessions. The DVTS transmitted over advanced networks such as Internet2 and APAN can provide the infrastructure for transmission of high-resolution, uncompressed video endoscopy for the purpose of teleteaching endoscopy.

    Low light level video is an important method of observation under low illumination condition, but the SNR of low light level video is low, the effect of observation is poor, so the noise reduction processing must be carried out. Low light level video noise mainly includes Gauss noise, Poisson noise, impulse noise, fixed pattern noise and dark current noise. In order to remove the noise in low-light-level video effectively, improve the quality of low-light-level video. This paper presents an improved time domain recursive filtering algorithm with three dimensional filtering coefficients. This algorithm makes use of the correlation between the temporal domain of the video sequence. In the video sequences, the proposed algorithm adaptively adjusts the local window filtering coefficients in space and time by motion estimation techniques, for the different pixel points of the same frame of the image, the different weighted coefficients are used. It can reduce the image tail, and ensure the noise reduction effect well. Before the noise reduction, a pretreatment based on boxfilter is used to reduce the complexity of the algorithm and improve the speed of the it. In order to enhance the visual effect of low-light-level video, an image enhancement algorithm based on guided image filter is used to enhance the edge of the video details. The results of experiment show that the hybrid algorithm can remove the noise of the low-light-level video effectively, enhance the edge feature and heighten the visual effects of video.

    2012-09-01

    A critical barrier to expanding simulation-based instruction in medicine is the availability of clinical instructors. Allowing instructors to remotely observe and debrief simulation sessions may make simulation-based instruction more convenient, thus expanding the pool of instructors available. This study compared the impact of simulation sessions facilitated by in-person (IP) faculty versus those supervised remotely using Web-conferencing software (WebEx(®), Cisco [ www.webex.com/ ]). A convenience sample of preclinical medical students volunteered to "care for" patients in a simulation laboratory. Students received either standard IP or Web-conferenced (WC) instruction. WC sessions were facilitated by off-site instructors. A satisfaction survey (5-point Likert scale, where 1=strongly disagree and 5=strongly agree) was completed immediately following the sessions. Forty-four surveys were analyzed (WC n=25, IP n=19). In response to the question "Was the communication between faculty and students a barrier to understanding the case?," the average student responses were 2.8 (95% confidence interval [CI] 2.4-3.2) for WC and 4.5 (95% CI 4.0-5.0) for IP (p4.0-4.5) for WC and 4.9 (95% CI 4.6-5.2) for IP (p=0.0003). Both groups agreed that they acquired new skills (4.2 for WC, 4.5 for IP; p=0.39) and new knowledge (4.6 for WC, 4.7 for IP; p=0.41). Telecommunication can successfully enhance access to simulation-based instruction. In this study, a Web interface downgraded the quality of student-faculty communication. Future investigation is needed to better understand the impact of such an effect on the learning process and to reduce barriers that impede implementation of technology-facilitated supervision.

    1996-03-01

    Interactive video and television viewers should have the power to control their viewing position. To make this a reality, we introduce the concept of Immersive Video, which employs computer vision and computer graphics technologies to provide remote users a sense of complete immersion when viewing an event. Immersive Video uses multiple videos of an event, captured from different perspectives, to generate a full 3D digital video of that event. That is accomplished by assimilating important information from each video stream into a comprehensive, dynamic, 3D model of the environment. Using this 3D digital video, interactive viewers can then move around the remote environment and observe the events taking place from any desired perspective. Our Immersive Video System currently provides interactive viewing and `walkthrus' of staged karate demonstrations, basketball games, dance performances, and typical campus scenes. In its full realization, Immersive Video will be a paradigm shift in visual communication which will revolutionize television and video media, and become an integral part of future telepresence and virtual reality systems.

    2009-05-01

    The H.264 video compression standard, aka MPEG 4 Part 10 aka Advanced Video Coding (AVC) allows new flexibility in the use of video in the battlefield. This standard necessitates encoder chips to effectively utilize the increased capabilities. Such chips are designed to cover the full range of the standard with designers of individual products given the capability of selecting the parameters that differentiate a broadcast system from a video conferencing system. The SmartCapture commercial product and the Universal Video Stick (UVS) military versions are about the size of a thumb drive with analog video input and USB (Universal Serial Bus) output and allow the user to select the parameters of imaging to the. Thereby, allowing the user to select video bandwidth (and video quality) using four dimensions of quality, on the fly, without stopping video transmission. The four dimensions are: 1) spatial, change from 720 pixel x 480 pixel to 320 pixel x 360 pixel to 160 pixel x 180 pixel, 2) temporal, change from 30 frames/ sec to 5 frames/sec, 3) transform quality with a 5 to 1 range, 4) and Group of Pictures (GOP) that affects noise immunity. The host processor simply wraps the H.264 network abstraction layer packets into the appropriate network packets. We also discuss the recently adopted scalable amendment to H.264 that will allow limit RAVC at any point in the communication chain by throwing away preselected packets.

    Full Text Available This paper presents an H.323 standard compliant virtual video conferencing system. The proposed system not only serves as a multipoint control unit (MCU for multipoint connection but also provides a gateway function between the H.323 LAN (local-area network and the H.324 WAN (wide-area network users. The proposed virtual video conferencing system provides user-friendly object compositing and manipulation features including 2D video object scaling, repositioning, rotation, and dynamic bit-allocation in a 3D virtual environment. A reliable, and accurate scheme based on background image mosaics is proposed for real-time extracting and tracking foreground video objects from the video captured with an active camera. Chroma-key insertion is used to facilitate video objects extraction and manipulation. We have implemented a prototype of the virtual conference system with an integrated graphical user interface to demonstrate the feasibility of the proposed methods.

    Incorporating technology with research is becoming increasingly important to enhance animal welfare in zoological settings. Video technology is used in the management of avian populations to facilitate efficient information collection on aspects of avian reproduction that are impractical or impossible to obtain through direct observation. Disney's Animal Kingdom(®) maintains a successful breeding colony of Northern carmine bee-eaters. This African species is a cavity nester, making their nesting behavior difficult to study and manage in an ex situ setting. After initial research focused on developing a suitable nesting environment, our goal was to continue developing methods to improve reproductive success and increase likelihood of chicks fledging. We installed infrared bullet cameras in five nest boxes and connected them to a digital video recording system, with data recorded continuously through the breeding season. We then scored and summarized nesting behaviors. Using remote video methods of observation provided much insight into the behavior of the birds in the colony's nest boxes. We observed aggression between birds during the egg-laying period, and therefore immediately removed all of the eggs for artificial incubation which completely eliminated egg breakage. We also used observations of adult feeding behavior to refine chick hand-rearing diet and practices. Although many video recording configurations have been summarized and evaluated in various reviews, we found success with the digital video recorder and infrared cameras described here. Applying emerging technologies to cavity nesting avian species is a necessary addition to improving management in and sustainability of zoo avian populations. © 2015 Wiley Periodicals, Inc.

    Technology can potentially expand the reach and cut the costs of providing effective, evidence-based interventions. This paper reviews existing publications that describe the application and evaluation of technology-assisted interventions for parents of young children. A broad review of the early childhood literature revealed 48 studies describing technology-assisted parent education and interventions. Across these studies, multiple forms of technology were used, including web-based platforms, discussion forums, mobile devices, and video conferencing. Results are described moving from feasibility and acceptability of technology-based delivery systems to more rigorous evaluations examining their impact on parent and child outcomes. Potential exists for technology to deliver interventions to parents. Limitations are discussed including differential acceptability and elevated attrition associated with internet-only intervention delivery. PMID:27773964

    The purpose of this paper is to determine the effectiveness of web-based video lectures on demand for the deaf in comparison to the traditional method of teaching using a sign language interpreter. The web-based lectures presented are specifically designed for the deaf in education and in rehabilitation. Sixty-three deaf students and adults were divided into four groups. All of the groups were made up of users who shared similar knowledge in the field of computers, but with different abilities in using computers, from beginners to advanced users. All of the groups were of mixed gender. The first two groups (consisting of 23 test users) graded the usability of the user interface for web-based lecture on demand with the help of the standardized SUMI questionnaire. After that, two groups (20 students from high school and 20 adults) joined in a 45-min informational program on the history of the deaf. Both groups were then divided into two smaller subgroups of 10 participants. The first subgroup in the first part of the learning program followed a traditional teaching style with the help of a teacher and an interpreter for Slovenian sign language. Meanwhile, the second group observed a 12-min web-based video lecture on demand and still had available an additional 18 min for a more detailed observation of the video. At the end of the lecture, the teacher used the questionnaire to review the participants' understanding of the content of the lecture in both of the groups. During the entire testing period, the interpreter used Slovenian sign language. By using the SUMI questionnaire, we determined the usability of the user interface for comprehension and gathering of knowledge. We discovered that the system was usable according to the standards. The global Median results (Global Median=51) were in the range of 50. In the second part of testing, we determined the level of significance between the traditional and web-based lectures. The results were statistically evaluated

    Information Communication Technology (ICT) has proven to be a strong public health tool. Keeping the future need of country and building National Disease Surveillance System, Integrated Disease Surveillance Project (IDSP) was launched by Hon'ble Union Minister of Health & Family Welfare in November 2004. It is a decentralized, State based surveillance program in the country. It is intended to detect early warning signals of impending outbreaks and help initiate an effective response in a timely manner. One of the major components of the project is the - use of Information Technology for collection, collation, compilation, analysis and dissemination of data besides distance education and video conferencing. A network of 800 sites across India has been established through Satellite, Broadband and High end Video conferencing equipments. The network is managed by a team of data managers and data entry operators at all state surveillance units and district surveillance units respectively. The network was proven to be extremely useful to respond to the current influenza A H1N1 pandemic. It is proposed to extend the network to cover private sector and provide convergence with other National Health Programs.

  1. Information technology resources assessment

    Energy Technology Data Exchange (ETDEWEB)

    Loken, S.C. [ed.

    1993-01-01

    The emphasis in Information Technology (IT) development has shifted from technology management to information management, and the tools of information management are increasingly at the disposal of end-users, people who deal with information. Moreover, the interactive capabilities of technologies such as hypertext, scientific visualization, virtual reality, video conferencing, and even database management systems have placed in the hands of users a significant amount of discretion over how these resources will be used. The emergence of high-performance networks, as well as network operating systems, improved interoperability, and platform independence of applications will eliminate technical barriers to the use of data, increase the power and range of resources that can be used cooperatively, and open up a wealth of possibilities for new applications. The very scope of these prospects for the immediate future is a problem for the IT planner or administrator. Technology procurement and implementation, integration of new technologies into the existing infrastructure, cost recovery and usage of networks and networked resources, training issues, and security concerns such as data protection and access to experiments are just some of the issues that need to be considered in the emerging IT environment. As managers we must use technology to improve competitiveness. When procuring new systems, we must take advantage of scalable resources. New resources such as distributed file systems can improve access to and efficiency of existing operating systems. In addition, we must assess opportunities to improve information worker productivity and information management through tedmologies such as distributed computational visualization and teleseminar applications.

    Floating Images, Inc. has developed the software and hardware for anew, patent pending, 'floating 3D, off-the- screen-experience' display technology. This technology has the potential to become the next standard for home and arcade video games, computers, corporate presentations, Internet/Intranet viewing, and television. Current '3D Graphics' technologies are actually flat on screen. Floating Images technology actually produce images at different depths from any display, such as CRT and LCD, for television, computer, projection, and other formats. In addition, unlike stereoscopic 3D imaging, no glasses, headgear, or other viewing aids are used. And, unlike current autostereoscopic imaging technologies, there is virtually no restriction on where viewers can sit to view the images, with no 'bad' or 'dead' zones, flipping, or pseudoscopy. In addition to providing traditional depth cues such as perspective and background image occlusion, the new technology also provides both horizontal and vertical binocular parallax and accommodation which coincides with convergence. Since accommodation coincides with convergence, viewing these images doesn't produce headaches, fatigue, or eye-strain, regardless of how long they are viewed. The imagery must either be formatted for the Floating Images platform when written, or existing software can be reformatted without much difficult. The optical hardware system can be made to accommodate virtually any projection system to produce Floating Images for the Boardroom, video arcade, stage shows, or the classroom.

    We introduce the internationalization promotion program conducted in Tomakomai National College of Technology (TNCT) . In order for the students to improve their international understanding and communication skills, the program was undertaken by means of collaborative education and distance education. TNCT delegates consisting of 2 teachers, 6 students, an office staff, and an engineer were sent to New Zealand, and worked on a project in cooperation with faculty members of Eastern Institute of Technology, Hawke‧s Bay (EIT) . The students explored environmental issues through discussions with other international students. At the end of the two-week on-site project, they reported the result via a video conferencing system. Additionally, this system served as a medium for international exchange in an intercultural communication class. Since the most of the students did not go to NZ, it was a good opportunity for them to communicate with people overseas. We discuss the effectiveness of both the collaborative education on practical topics and the distance education using a video conferencing system.

    Coral colony size-frequency distribution data offer valuable information about the ecological status of coral reefs. Such data are usually collected by divers in situ, but stereo video is being increasingly used for monitoring benthic marine communities and may be used to collect size information for coral colonies. This study compared the size-frequency distributions of coral colonies obtained by divers measuring colonies 'in situ' with digital video imagery collected using stereo video and later processed using computer software. The size-frequency distributions of the two methods were similar for corymbose colonies, although distributions were different for massive, branching and all colonies combined. The differences are mainly driven by greater abundance of colonies >50 cm and fewer colonies 5 cm and was able to record measurements on 87% of the colonies detected. However, stereo video only detected 57% of marked colonies coral recruits. Estimates of colony size made with the stereo video were smaller than the in situ technique for all growth forms, particularly for massive morphologies. Despite differences in size distributions, community assessments, which incorporated genera, growth forms and size, were similar between the two techniques. Stereo video is suitable for monitoring coral community demographics and provided data similar to in situ measure for corymbose corals, but the ability to accurately measure massive and branching coral morphologies appeared to decline with increasing colony size.

    2004-05-01

    Full Text Available The aim of this paper is to describe a task-cycling pedagogy for language learning using a technique we have called Stimulated Reflection. This pedagogical approach has been developed in the light of the new technology options available, especially those that facilitate audiovisual forms of interaction among language learners and teachers. In this instance, the pedagogy is implemented in the context of introducing students to audio-conferencing (A-C tools as a support for their ongoing independent learning. The approach is designed to develop a balance for learners between attention to fluency and meaning on one hand, and form and accuracy on the other. The particular focus here is on the learning of Italian as a foreign language, although the ideas and principles are presented with a view to the teaching and learning of any language. The article is in three parts. The first considers appropriate theoretical frameworks for the use of technology-mediated tools in language learning, with a particular emphasis on the focus-on-form literature and task design (Doughty, 2003; Doughty & Williams, 1998; Skehan, 1998. The second part sets out the approach we have taken in the Italian project and discusses specifically the idea of task cycling (Willis, 1996 and Stimulated Reflection. The third part presents extracts of stimulated reflection episodes that serve to illustrate the new pedagogic approach.

    2003-10-01

    Full Text Available Real-Time services are traditionally supported on circuit switched network. However, there is a need to port these services on packet switched network. Architecture for audio conferencing application over the Internet in the light of ITU-T H.323 recommendations is considered. In a conference, considering packets only from a set of selected clients can reduce speech quality degradation because mixing packets from all clients can lead to lack of speech clarity. A distributed algorithm and architecture for selecting clients for mixing is suggested here based on a new quantifier of the voice activity called "Loudness Number" (LN. The proposed system distributes the computation load and reduces the load on client terminals. The highlights of this architecture are scalability, bandwidth saving and speech quality enhancement. Client selection for playing out tries to mimic a physical conference where the most vocal participants attract more attention. The contributions of the paper are expected to aid H.323 recommendations implementations for Multipoint Processors (MP. A working prototype based on the proposed architecture is already functional.

    2010-01-01

    Full Text Available The objective of the Basic Competences is to highlight the essential learning of the Secondary School Curriculum. The fourth Basic Competence introduces in the Secondary School Program the use of the Information and Communication Technologies as an essential element to be informed, to learn and to communicate. To that effect, this article tries to bring the new technologies to the Physical Education Class, specifically to the analysis of the vertical jump. This jump has been traditionally evaluated with the Sargent’s test but this test has some errors which derive from the measuring process. Nowadays there are new very precise instruments often used in sports for the analysis of the vertical jump, but their high prices make it difficult to introduce them in the school. With this article we want to show that the digital video recording and the video edition programs constitute a very appropriate way to evaluate the vertical jump because it causes in the students great interest and implication.

    This paper analyzes the outstanding problems in current industrial production by reviewing the three stages of the Industrial Engineering Development. Based on investigations and interviews in enterprises, we propose the new idea of applying "computer video analysis technology" to new industrial engineering management software, and add "loose-coefficient" of the working station to this software in order to arrange scientific and humanistic production. Meanwhile, we suggest utilizing Biofeedback Technology to promote further research on "the rules of workers' physiological, psychological and emotional changes in production". This new kind of combination will push forward industrial engineering theories and benefit enterprises in progressing towards flexible social production, thus it will be of great theory innovation value, social significance and application value.

  19. Video over DSL with LDGM Codes for Interactive Applications

    Directory of Open Access Journals (Sweden)

    Laith Al-Jobouri

    2016-05-01

    Full Text Available Digital Subscriber Line (DSL network access is subject to error bursts, which, for interactive video, can introduce unacceptable latencies if video packets need to be re-sent. If the video packets are protected against errors with Forward Error Correction (FEC, calculation of the application-layer channel codes themselves may also introduce additional latency. This paper proposes Low-Density Generator Matrix (LDGM codes rather than other popular codes because they are more suitable for interactive video streaming, not only for their computational simplicity but also for their licensing advantage. The paper demonstrates that a reduction of up to 4 dB in video distortion is achievable with LDGM Application Layer (AL FEC. In addition, an extension to the LDGM scheme is demonstrated, which works by rearranging the columns of the parity check matrix so as to make it even more resilient to burst errors. Telemedicine and video conferencing are typical target applications.

    2002-03-01

    We are developing a multiple-angle 3D-video system that will allow an audience to enjoy a concert in real time at a distant location by simultaneously shooting multiple stereoscopic images from different angles and transmitting them through a high-speed network. At the receiving side, a decoder restores the original image signals from the received data, and different video images are shown on multiple stereoscopic displays. As a result, the audience can enjoy multiple images of a concert at the same time. The purpose of this system is to give a remote audience the opportunity to enjoy a live concert as though they were at the concert site. This paper examines the technical requirements for the camera arrangement and the transmission rate needed to transmit images of a musical performance with this system. We have built an experimental system with four stereo cameras, and have experimentally transmitted musical performance images to test the system performance. In this paper, we also propose a method for transmitting multiple camera images more efficiently.

    Lower Granite Dam on the Snake River to evaluate the feasibility of using video technology to document and estimate fish ladder passage of chinook salmon Oncorhynchus tshawytscha, sockeye salmon O. nerka, and steelhead O. mykiss. A video system was to produced video images during salmon passage periods. A technician identified and counted fish images from the video record. Fish ladder passage estimates of target species made from the video record were similar to estimates made by on-site counters during daytime periods, indicating that the two methods were relatively precise. We also found that a significant percentage (6.4% and 8.3%) of target salmonids migrated during nighttime periods when on-site counts were not typically made during the two years of study. Analysis of the video record permitted verification of individual sockeye salmon identified and counted by on-site count personnel, and provided data useful to managers of this ESA-listed stock. Analysis of the video record also permitted collection of additional data such as length measurements of individual specimens, which was used to regulate a fishery located upstream.

    To determine the impact of simulations using an alternative method of communication on students' satisfaction, attitudes, confidence, and performance related to interprofessional communication. One hundred sixty-three pharmacy students participated in a required applications-based capstone course. Students were randomly assigned to one of three interprofessional education (IPE) simulations with other health professions students using communication methods such as telephone, e-mail, and video conferencing. Pharmacy students completed a validated survey instrument, Attitude Toward Healthcare Teams Scale (ATHCTS) prior to and after course participation. Significant positive changes occurred for 5 out of 20 items. Written reflection papers and student satisfaction surveys completed after participation showed positive themes and satisfaction. Course instructors evaluated student performance using rubrics for formative feedback. Implementation of IPE simulations using various methods of communication technology is an effective way for pharmacy schools to incorporate IPE into their curriculum.

    2013-03-01

    Full Text Available Technology Acceptance Model (TAM is a measure to assess the underlying reasons about the use of a technology. In this study an extended version of TAM were used. This extended version composed of three factors. These are “perceived motivation towards learning environment”, “perceived usefulness” and “perceived ease of use”. In this study, the learning environment of a distance course was investigated to see students’ perceptions. This distance course was delivered from one university to the other university via video-conferencing with ITL Learning Gateway content management system during the whole semester. The participants were the 32 first year vocational higher education institution students. The descriptive findings revealed that each factor of TAM perceived by students as having moderate advantages. It is believed that the underlying reason of this situation was based on the students’ low computer competency and e-learning experiences.

    2015-08-01

    Full Text Available Distance learning has provided an excellent platform for students in geographically remote locations while enabling them to learn at their own pace and convenience. A number of technologies are currently being utilized to conceptualize, design, enhance and foster distance learning. Teleconferences, electronic field trips, podcasts, webinars, video conferencing and online courses are among such technologies used in providing distance learning opportunities. However limitations in those existing technologies have affected to the increase of distance learners dropout rates. As an attempt to overcome the limitations in the currently adopted distance learning practices, the study aims to utilize 3D Hologram Technology (3DHT in the Engineering discipline. 3D hologram facilitates live and life size 3D telepresence that can interact with remote audiences. A survey had been conducted, using Delphi Technique to gather data from the experts in the field to evaluate the potential of 3DHT over existing technologies. Results of the survey suggested that 3DHT as a good distance learning technology and have the potential of overcoming existing limitations. Lack of infrastructure, High initial cost of infrastructure and Lack of technical know how are the main encounters identified by the experts in the sample. It is expected to develop a classroom environment with 3DHT and to evaluate its effectiveness for the distance learning in the next stage of the study.

    Ray, Robin A; Fried, Ofra; Lindsay, Daniel

    2014-06-19

    People living in rural and remote locations are disadvantaged in accessing palliative care. This can be attributed to several factors including the role diversity and the low numbers of patients with specific conditions, as well as the difficulties rural health practitioners have in accessing opportunities for professional education. A program of multidisciplinary palliative care video conferences was presented to health practitioners across part of northern Australia in an effort to address this problem. The educational content of the video conferences was developed from participant responses to an educational needs assessment. Following cycles of four consecutive video conferences, 101 participants completed evaluative on-line surveys. The quantitative data were analysed using frequencies and analysis of variance tests with post-hoc analyses where appropriate, and an accessibility and remoteness index was used to classify their practice location. All participants found the content useful regardless of their remoteness from the tertiary centre, their years of experience caring for palliative care patients or the number of patients cared for each year. However, change in confidence to provide palliative care as a result of attending the video conferences was significant across all disciplines, regardless of location. Doctors, medical students and allied health professionals indicated the greatest change in confidence. The provision of professional education about palliative care issues via multidisciplinary video conferencing increased confidence among rural health practitioners, by meeting their identified need for topic and context specific education. This technology also enhanced the networking opportunities between practitioners, providing an avenue of ongoing professional support necessary for maintaining the health workforce in rural and remote areas. However, more attention should be directed to the diverse educational needs of allied health professionals.

  7. Social Properties of Mobile Video

    Mitchell, April Slayden; O'Hara, Kenton; Vorbau, Alex

    Mobile video is now an everyday possibility with a wide array of commercially available devices, services, and content. These new technologies have created dramatic shifts in the way video-based media can be produced, consumed, and delivered by people beyond the familiar behaviors associated with fixed TV and video technologies. Such technology revolutions change the way users behave and change their expectations in regards to their mobile video experiences. Building upon earlier studies of mobile video, this paper reports on a study using diary techniques and ethnographic interviews to better understand how people are using commercially available mobile video technologies in their everyday lives. Drawing on reported episodes of mobile video behavior, the study identifies the social motivations and values underpinning these behaviors that help characterize mobile video consumption beyond the simplistic notion of viewing video only to kill time. This paper also discusses the significance of user-generated content and the usage of video in social communities through the description of two mobile video technology services that allow users to create and share content. Implications for adoption and design of mobile video technologies and services are discussed as well.

    Full Text Available Learning Management System (LMS supports e-learning as a distant learning. Moodle is one of open source LMS applications that allow embedding multimedia into learning activity in a course, such as video conference session. The paper investigates quality of service (QoS of video conference session embedded in Moodle, i.e. end-to-end delay, jitter, throughput, packet loss and PSNR. Three scenarios were implemented in the experiment. The scenarios were applied on both wire and wireless transmission, and p2p and p2m connections. The investigation results show that the QoS of video conference session meets the standards issued by ITU-T G.1010 and G.114, for minimum bandwidth of 128 kbps. Thus the application of video conferencing that is integrated in Moodle can run well with minimum bandwidth of 128 Kbps.

    Kite, James; Phongsavan, Philayrath

    2017-01-01

    Background Online focus groups have been increasing in use over the last 2 decades, including in biomedical and health-related research. However, most of this research has made use of text-based services such as email, discussion boards, and chat rooms, which do not replicate the experience of face-to-face focus groups. Web conferencing services have the potential to more closely match the face-to-face focus group experience, including important visual and aural cues. This paper provides critical reflections on using a web conferencing service to conduct online focus groups. Methods As part of a broader study, we conducted both online and face-to-face focus groups with participants. The online groups were conducted in real-time using the web conferencing service, Blackboard Collaborate TM. We used reflective practice to assess how the conduct and content of the groups were similar and how they differed across the two platforms. Results We found that further research using such services is warranted, particularly when working with hard-to-reach or geographically dispersed populations. The level of discussion and the quality of the data obtained was similar to that found in face-to-face groups. However, some issues remain, particularly in relation to managing technical issues experienced by participants and ensuring adequate recording quality to facilitate transcription and analysis. Conclusions Our experience with using web conferencing for online focus groups suggests that they have the potential to offer a realistic and comparable alternative to face-to-face focus groups, especially for geographically dispersed populations such as rural and remote health practitioners. Further testing of these services is warranted but researchers should carefully consider the service they use to minimise the impact of technical difficulties.

    To determine the effect of a new automated external defibrillator (AED) system connected by General Packet Radio Service (GPRS) to an external call centre in assisting novices in a sudden cardiac arrest situation. Prospective, interventional study. Layperson volunteers were first asked to complete a survey about their knowledge and ability to give cardiopulmonary resuscitation (CPR) and use an AED. A simulated cardiac arrest scenario using a CPR manikin was then presented to volunteers. A telephone and semi-AED were available in the same room. The AED was linked to a call centre, which provided real-time information to 'bystanders' and emergency services via GPRS/GPS technology. The scene was videotaped to avoid any interaction with examiners. A standardised check list was used to record correct actions. 85 volunteers completed questionnaires and were recorded. Mean age was 44±16, and 49% were male; 38 (45%) had prior CPR training or felt comfortable intervening in a sudden cardiac arrest victim; 40% felt they could deliver a shock using an AED. During the scenarios, 56 (66%) of the participants used the AED and 53 (62%) successfully delivered an electrical shock. Mean time to defibrillation was 2 min 29 s. Only 24 (28%) participants dialled the correct emergency response number (112); the live-assisted GPRS AED allowed alerted emergency services in 38 other cases. CPR was initiated in 63 (74%) cases, 26 (31%) times without prompting and 37 (44%) times after prompting by the AED. Although knowledge of the general population appears to be inadequate with regard to AED locations and recognition, live-assisted devices with GPS-location may improve emergency care.

    2004-01-01

    Full Text Available In order to respond to learners' need for more flexible speaking opportunities and to overcome the geographical challenge of students spread over the United Kingdom and continental Western Europe, the Open University recently introduced Internet-based, real-time audio conferencing, thus making a groundbreaking move in the distance learning and teaching of languages. Since February 2002, online tutorials for language courses have been offered using Lyceum, an Internet-based audio-graphics conferencing tool developed in house. Our research is based on the first Open University course ever to deliver tutorials solely online, a level 2 German course, and this article considers some of the challenges of implementing online tuition. As a starting point, we present the pedagogical rationale underpinning the virtual learning and teaching environment. Then we examine the process of development and implementation of online tuition in terms of activity design, tutor training, and student support. A number of methodological tools such as logbooks, questionnaires, and observations were used to gather data. The findings of this paper highlight the complexity of the organisational as well as the pedagogical framework that contributes to the effective use of online tuition via audio conferencing systems in a distance education setting.

    1998-12-01

    Full Text Available A l’Open University, université britannique de télé-enseignement, les concepteurs de matériaux utilisent depuis longtemps des pédagogies qui amènent l’apprenant à réfléchir sur son apprentissage et à expliciter cette réflexion. Or aujourd’hui les Technologies de l’Information et de la Communication (TIC leur permettent de faire interagir apprenants, professeurs et locuteurs natifs. Ainsi l’apprenant participe à la communication et reçoit en retour des messages en langue cible, dont il se sert pour améliorer sa compétence communicative. Qu’en est-il, dès lors, du rôle de la réflexion consciente dans le processus d’apprentissage ? Vu les importantes possibilités d’interactivité offertes par les TIC, doit-on encore prôner la réflexion consciente dans le télé-enseignement ? Nous répondons par l’affirmative, considérant que les concepteurs d’environnements virtuels doivent faciliter et la réflexion consciente et l’interactivité spontanée. Nous soutenons que la conférence télématique asynchrone est un outil qui permet d’atteindre cet objectif. Nous cherchons à voir dans quelle mesure la réflexivité et l’interactivité interviennent dans ce type de conférence, et à préciser la valeur pédagogique de ces échanges. Nous étudions une conférence organisée pour des étudiants de français langue étrangère (FLE et nous proposons une pédagogie visant à promouvoir ce que nous appelons des "conversations réflexives", c’est-à-dire des échanges privilégiant des thèmes langagiers ou portant sur l’apprentissage même des langues.In the UK Open University the principle that distance language learners should be encouraged to reflect on their own learning has traditionally been central to the design of conventional (i.e. print , audio and video course materials.

    2001-01-01

    Through a licensing agreement, Intergraph Government Solutions adapted a technology originally developed at NASA's Marshall Space Flight Center for enhanced video imaging by developing its Video Analyst(TM) System. Marshall's scientists developed the Video Image Stabilization and Registration (VISAR) technology to help FBI agents analyze video footage of the deadly 1996 Olympic Summer Games bombing in Atlanta, Georgia. VISAR technology enhanced nighttime videotapes made with hand-held camcorders, revealing important details about the explosion. Intergraph's Video Analyst System is a simple, effective, and affordable tool for video enhancement and analysis. The benefits associated with the Video Analyst System include support of full-resolution digital video, frame-by-frame analysis, and the ability to store analog video in digital format. Up to 12 hours of digital video can be stored and maintained for reliable footage analysis. The system also includes state-of-the-art features such as stabilization, image enhancement, and convolution to help improve the visibility of subjects in the video without altering underlying footage. Adaptable to many uses, Intergraph#s Video Analyst System meets the stringent demands of the law enforcement industry in the areas of surveillance, crime scene footage, sting operations, and dash-mounted video cameras.

  1. Reflections on academic video

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available As academics we study, research and teach audiovisual media, yet rarely disseminate and mediate through it. Today, developments in production technologies have enabled academic researchers to create videos and mediate audiovisually. In academia it is taken for granted that everyone can write a text. Is it now time to assume that everyone can make a video essay? Using the online journal of academic videos Audiovisual Thinking and the videos published in it as a case study, this article seeks to reflect on the emergence and legacy of academic audiovisual dissemination. Anchoring academic video and audiovisual dissemination of knowledge in two critical traditions, documentary theory and semiotics, we will argue that academic video is in fact already present in a variety of academic disciplines, and that academic audiovisual essays are bringing trends and developments that have long been part of academic discourse to their logical conclusion.

The outcome of the research was the creation of a charity video, Crosscause: Making a Difference, to showcase humanitarian work in Ireland and Romania with a view to inspiring others to contribute in some capacity to this cause. Video is an important medium to provide connections with a wider audience, as it gives humanitarian workers and marginalised communities an opportunity to tell their story by making a compelling and evocative case to others. Visual media not only makes connections with an audience, but can also positively challenge people to consider what is happening in the world around them.

    Full Text Available This report examines three text-based conferencing products: WowBB, Invision Power Board, and vBulletin. Their selection was prompted by a feature-by-feature comparison of the same products on the WowBB website. The comparison chart painted a misleading impression of WowBB’s features in relation to the other two products; so the evaluation team undertook a more comprehensive and impartial comparison using the categories and criteria for online software evaluation developed by the American Society for Training and Development (ASTD. The findings are summarised in terms of the softwares’ pricing, common features/ functions, and differentiating features.

    The outreach and education components of the International Space Station Program are creating a number of materials, programs, and activities that educate and inform various groups as to the implementation and purposes of the International Space Station. One of the strategies for disseminating this information to K-12 students involves an electronic class room using state of the art video conferencing technology. K-12 classrooms are able to visit the JSC, via an electronic field trip. Students interact with outreach personnel as they are taken on a tour of ISS mockups. Currently these events can be generally characterized as: Being limited to a one shot events, providing only one opportunity for students to view the ISS mockups; Using a "one to many" mode of communications; Using a transmissive, lecture based method of presenting information; Having student interactions limited to Q&A during the live event; Making limited use of media; and Lacking any formal, performance based, demonstration of learning on the part of students. My project involved developing interactive lessons for K-12 students (specifically 7th grade) that will reflect a 2nd generation design for electronic field trips. The goal of this design will be to create electronic field trips that will: Conform to national education standards; More fully utilize existing information resources; Integrate media into field trip presentations; Make support media accessible to both presenters and students; Challenge students to actively participate in field trip related activities; and Provide students with opportunities to demonstrate learning

    Siblings of children with chronic illness and disabilities are at increased risk of negative psychological effects. Support groups enable them to access psycho-education and social support. Barriers to this can include the distance they have to travel to meet face-to-face. Audio-conferencing, whereby three or more people can connect by telephone in different locations, is an efficient means of groups meeting and warrants exploration in this healthcare context. This study explored the feasibility of audio-conferencing as a method of facilitating sibling support groups. A longitudinal design was adopted. Participants were six siblings (aged eight to thirteen years) and parents of children with complex neurodevelopmental disorders attending the Centre for Interventional Paediatric Psychopharmacology (CIPP). Four of the eight one-hour weekly sessions were held face-to-face and the other four using audio-conferencing. Pre- and post-intervention questionnaires and interviews were completed and three to six month follow-up interviews were carried out. The sessions were audio-recorded, transcribed and thematic analysis was undertaken. Audio-conferencing as a form of telemedicine was acceptable to all six participants and was effective in facilitating sibling support groups. Audio-conferencing can overcome geographical barriers to children being able to receive group therapeutic healthcare interventions such as social support and psycho-education. Psychopathology ratings increased post-intervention in some participants. Siblings reported that communication between siblings and their family members increased and siblings' social network widened. Audio-conferencing is an acceptable, feasible and effective method of facilitating sibling support groups. Siblings' clear accounts of neuropsychiatric symptoms render them reliable informants. Systematic assessment of siblings' needs and strengthened links between Child and Adolescent Mental Health Services, school counsellors and

    Floating Images, Inc. has developed the software and hardware for a new, patent pending, 'floating 3-D, off-the-screen- experience' display technology. This technology has the potential to become the next standard for home and arcade video games, computers, corporate presentations, Internet/Intranet viewing, and television. Current '3-D graphics' technologies are actually flat on screen. Floating ImagesTM technology actually produce images at different depths from any display, such as CRT and LCD, for television, computer, projection, and other formats. In addition, unlike stereoscopic 3-D imaging, no glasses, headgear, or other viewing aids are used. And, unlike current autostereoscopic imaging technologies, there is virtually no restriction on where viewers can sit to view the images, with no 'bad' or 'dead' zones, flipping, or pseudoscopy. In addition to providing traditional depth cues such as perspective and background image occlusion, the new technology also provides both horizontal and vertical binocular parallax (the ability to look around foreground objects to see previously hidden background objects, with each eye seeing a different view at all times) and accommodation (the need to re-focus one's eyes when shifting attention from a near object to a distant object) which coincides with convergence (the need to re-aim one's eyes when shifting attention from a near object to a distant object). Since accommodation coincides with convergence, viewing these images doesn't produce headaches, fatigue, or eye-strain, regardless of how long they are viewed (unlike stereoscopic and autostereoscopic displays). The imagery (video or computer generated) must either be formatted for the Floating ImagesTM platform when written or existing software can be re-formatted without much difficulty.

    The aims of this quasi-experimental before-and-after study were to first determine whether the use of eye tracking technology combined with video debriefing techniques has the potential to improve the quality of feedback and enhance situation awareness (SA) in simulated settings and second to determine students' satisfaction towards simulated learning. Nursing and paramedicine students from three universities participated in three 8-minute simulation scenarios of acutely deteriorating patients. Eye tracking glasses video recorded the scenarios and tracked right eye movement. On completion, participants were questioned using the Situation Awareness Global Assessment Technique, completed the Satisfaction with Simulation Experience Scale (SSES), and provided textual feedback and received video-based verbal feedback. Participants lacked awareness of presenting medical conditions and patient environments and had poor recall of patient vital signs. Significant improvements in SA scores were demonstrated between the first and third scenarios (P = 0.04). Participants reported greater insight into their performance and were satisfied with simulated learning. Use of visual field review techniques appears to enhance the use of realistic simulated practice as a means of addressing significant performance deficits. Eye tracking and point of view recording techniques are feasible and with applicable debriefing techniques could enhance clinical and situated performance. Copyright © 2014 Elsevier Ltd.

    The use of information and communication technologies (ICTs) for information sharing among family members is increasing dramatically. However, little is known about the associated factors and the influence on family well-being. The authors investigated the pattern and social determinants of family life information sharing with family and the associations of different methods of sharing with perceived family health, happiness, and harmony (3Hs) in Hong Kong, where mobile phone ownership and Internet access are among the most prevalent, easiest, and fastest in the world. A territory-wide population-based telephone survey was conducted from January to August 2016 on different methods of family life information (ie, information related to family communication, relationships with family members, emotion and stress management) sharing with family members, including face-to-face, phone, instant messaging (IM), social media sites, video calls, and email. Family well-being was assessed by three single items on perceived family health, happiness, and harmony, with higher scores indicating better family well-being. Adjusted prevalence ratios were used to assess the associations of sociodemographic factors with family life information sharing, and adjusted beta coefficients for family well-being. Of 2017 respondents, face-to-face was the most common method to share family life information (74.45%, 1502/2017), followed by IM (40.86%, 824/2017), phone (28.10%, 567/2017), social media sites (11.91%, 240/2017), video calls (5.89%, 119/2017), and email (5.48%, 111/2017). Younger age and higher education were associated with the use of any (at least one) method, face-to-face, IM, and social media sites for sharing family life information (all P for trend information was associated with a higher level of perceived family well-being (beta=0.56, 95% CI 0.37-0.75), especially by face-to-face (beta=0.62, 95% CI 0.45-0.80) and video calls (beta=0.34, 95% CI 0.04-0.65).

    The process of digital capture, editing, and archiving video has become an important aspect of documenting arthroscopic surgery. Recording the arthroscopic findings before and after surgery is an essential part of the patient's medical record. The hardware and software has become more reasonable to purchase, but the learning curve to master the software is steep. Digital video is captured at the time of arthroscopy to a hard disk, and written to a CD at the end of the operative procedure. The process of obtaining video of open procedures is more complex. Outside video of the procedure is recorded on digital tape with a digital video camera. The camera must be plugged into a computer to capture the video on the hard disk. Adobe Premiere software is used to edit the video and render the finished video to the hard drive. This finished video is burned onto a CD. We outline the choice of computer hardware and software for the manipulation of digital video. The techniques of backup and archiving the completed projects and files also are outlined. The uses of digital video for education and the formats that can be used in PowerPoint presentations are discussed.

    The Seattle-King County Hazardous Waste Management Plan provides the framework for an intensive effort to keep Household Hazardous Waste (HHW) and Small Quantity Generator (SQG) wastes from entering the municipal solid and liquid waste streams. Many innovative programs for managing small sources of hazardous waste have been developed in response to the Plan. With the assistance of Urban Consortium grants, the City of Seattle has researched and developed a series of reports describing the planning, operation and evaluation of the plan's HHW collection programs. Three of the Plan's programs of particular interest to other jurisdictions are the fixed site and mobile HHW Collection Facilities, and the Business Waste Consultations provided to SQG's. In 1991, Seattle received an Urban Consortium grant to produce two videos showing how the HHW Collection Facilities and Business Consultations programs work. This report provides an overviews of the video development and production process and a discussion of the lessons learned by the staff directing the production.

    Restorative justice is "a process whereby parties with a stake in a specific offence resolve collectively how to deal with the aftermath of the offence and its implications for the future" (Marshall 2003). Despite the increasing use of restorative justice programmes as an alternative to court proceedings, no systematic review has been undertaken of the available evidence on the effectiveness of these programmes with young offenders. Recidivism in young offenders is a particularly worrying problem, as recent surveys have indicated the frequency of re-offences for young offenders has ranged from 40.2% in 2000 to 37.8% in 2007 (Ministry of Justice 2009) To evaluate the effects of restorative justice conferencing programmes for reducing recidivism in young offenders. We searched the following databases up to May 2012: CENTRAL, 2012 Issue 5, MEDLINE (1978 to current), Bibliography of Nordic Criminology (1999 to current), Index to Theses (1716 to current), PsycINFO (1887 to current), Social Sciences Citation Index (1970 to current), Sociological Abstracts (1952 to current), Social Care Online (1985 to current), Restorative Justice Online (1975 to current), Scopus (1823 to current), Science Direct (1823 to current), LILACS (1982 to current), ERIC (1966 to current), Restorative Justice Online (4 May 2012), WorldCat (9 May 2012), ClinicalTrials.gov (19 May 2012) and ICTRP (19 May 2012). ASSIA, National Criminal Justice Reference Service and Social Services Abstracts were searched up to May 2011. Relevant bibliographies, conference programmes and journals were also searched. Randomised controlled trials (RCTs) or quasi-RCTs of restorative justice conferencing versus management as usual, in young offenders. Two authors independently assessed the risk of bias of included trials and extracted the data. Where necessary, original investigators were contacted to obtain missing information. Four trials including a total of 1447 young offenders were included in the review. Results

    Background Palliative care planning for nursing home residents with advanced dementia is often suboptimal. This study compared effects of facilitated case conferencing (FCC) with usual care (UC) on end-of-life care. Methods A two arm parallel cluster randomised controlled trial was conducted. The sample included people with advanced dementia from 20 Australian nursing homes and their families and professional caregivers. In each intervention nursing home (n = 10), Palliative Care Planning Coordinators (PCPCs) facilitated family case conferences and trained staff in person-centred palliative care for 16 hours per week over 18 months. The primary outcome was family-rated quality of end-of-life care (End-of-Life Dementia [EOLD] Scales). Secondary outcomes included nurse-rated EOLD scales, resident quality of life (Quality of Life in Late-stage Dementia [QUALID]) and quality of care over the last month of life (pharmacological/non-pharmacological palliative strategies, hospitalization or inappropriate interventions). Results Two-hundred-eighty-six people with advanced dementia took part but only 131 died (64 in UC and 67 in FCC which was fewer than anticipated), rendering the primary analysis under-powered with no group effect seen in EOLD scales. Significant differences in pharmacological (P life were seen. Intercurrent illness was associated with lower family-rated EOLD Satisfaction with Care (coefficient 2.97, P care.

  16. Error and Congestion Resilient Video Streaming over Broadband Wireless

    Directory of Open Access Journals (Sweden)

    Laith Al-Jobouri

    2015-04-01

    Full Text Available In this paper, error resilience is achieved by adaptive, application-layer rateless channel coding, which is used to protect H.264/Advanced Video Coding (AVC codec data-partitioned videos. A packetization strategy is an effective tool to control error rates and, in the paper, source-coded data partitioning serves to allocate smaller packets to more important compressed video data. The scheme for doing this is applied to real-time streaming across a broadband wireless link. The advantages of rateless code rate adaptivity are then demonstrated in the paper. Because the data partitions of a video slice are each assigned to different network packets, in congestion-prone wireless networks the increased number of packets per slice and their size disparity may increase the packet loss rate from buffer overflows. As a form of congestion resilience, this paper recommends packet-size dependent scheduling as a relatively simple way of alleviating the buffer-overflow problem arising from data-partitioned packets. The paper also contributes an analysis of data partitioning and packet sizes as a prelude to considering scheduling regimes. The combination of adaptive channel coding and prioritized packetization for error resilience with packet-size dependent packet scheduling results in a robust streaming scheme specialized for broadband wireless and real-time streaming applications such as video conferencing, video telephony, and telemedicine.

    Full Text Available As the public education system in Northern Ontario continues to take a downward spiral, a plethora of secondary school students are being placed in an alternative educational environment. Juxtaposing the two educational settings reveals very similar methods and characteristics of educating our youth as opposed to using a truly alternative approach to education. This video reviews the relationship between public education and alternative education in a remote Northern Ontario setting. It is my belief that the traditional methods of teaching are not appropriate in educating at risk students in alternative schools. Paper and pencil worksheets do not motivate these students to learn and succeed. Alternative education should emphasize experiential learning, a just in time curriculum based on every unique individual and the students true passion for everyday life. Cameron Culbert was born on February 3rd, 1977 in North Bay, Ontario. His teenage years were split between attending public school and his willed curriculum on the ski hill. Culbert spent 10 years (1996-2002 & 2006-2010 competing for Canada as an alpine ski racer. His passion for teaching and coaching began as an athlete and has now transferred into the classroom and the community. As a graduate of Nipissing University (BA, BEd, MEd. Camerons research interests are alternative education, physical education and technology in the classroom. Currently Cameron is an active educator and coach in Northern Ontario.

  1. Environmental cognitive remediation in schizophrenia: ethical implications of "smart home" technology.

    Stip, Emmanuel; Rialle, Vincent

    2005-04-01

    In light of the advent of new technologies, we proposed to reexamine certain challenges posed by cognitive remediation and social reintegration (that is, deinstitutionalization) of patients with severe and persistent mental disorders. We reviewed literature on cognition, remediation, smart homes, as well as on objects and utilities, using medical and computer science electronic library and Internet searches. These technologies provide solutions for disabled persons with respect to care delivery, workload reduction, and socialization. Examples include home support, video conferencing, remote monitoring of medical parameters through sensors, teledetection of critical situations (for example, a fall or malaise), measures of daily living activities, and help with tasks of daily living. One of the key concepts unifying all these technologies is the health-smart home. We present the notion of the health-smart home in general and then examine it more specifically in relation to schizophrenia. Management of people with schizophrenia with cognitive deficits who are being rehabilitated in the community can be improved with the use of technology; however, such technology has ethical ramifications.

  2. Coral Reef Surveillance: Infrared-Sensitive Video Surveillance Technology as a New Tool for Diurnal and Nocturnal Long-Term Field Observations.

    2012-10-31

    Direct field observations of fine-scaled biological processes and interactions of the benthic community of corals and associated reef organisms (e.g., feeding, reproduction, mutualistic or agonistic behavior, behavioral responses to changing abiotic factors) usually involve a disturbing intervention. Modern digital camcorders (without inflexible land-or ship-based cable connection) such as the GoPro camera enable undisturbed and unmanned, stationary close-up observations. Such observations, however, are also very time-limited (~3 h) and full 24 h-recordings throughout day and night, including nocturnal observations without artificial daylight illumination, are not possible. Herein we introduce the application of modern standard video surveillance technology with the main objective of providing a tool for monitoring coral reef or other sessile and mobile organisms for periods of 24 h and longer. This system includes nocturnal close-up observations with miniature infrared (IR)-sensitive cameras and separate high-power IR-LEDs. Integrating this easy-to-set up and portable remote-sensing equipment into coral reef research is expected to significantly advance our understanding of fine-scaled biotic processes on coral reefs. Rare events and long-lasting processes can easily be recorded, in situ-experiments can be monitored live on land, and nocturnal IR-observations reveal undisturbed behavior. The options and equipment choices in IR-sensitive surveillance technology are numerous and subject to a steadily increasing technical supply and quality at decreasing prices. Accompanied by short video examples, this report introduces a radio-transmission system for simultaneous recordings and real-time monitoring of multiple cameras with synchronized timestamps, and a surface-independent underwater-recording system.

  3. Development of Technological and Pedagogical Content Knowledge of the Chemistry by Teachers in Training Through the Reflection of PaP-eRs and Videos

    2018-01-01

    Full Text Available This article described how trainee teachers identified and developed some elements of the Technological and Pedagogical Knowledge of Chemistry Content (CTPC, along the course of educational and pedagogical context by "reflective orientation". The methodological perspective was qualitative by case study, which was configured by two interwoven areas of reflection, namely: (a reflecting on the opinions of experts about the teaching of a content, through the readings proposed in the training programs; and (b reflecting on the teaching carried out by experienced teachers through case videos and the Repertoire of Professional and Pedagogical Experiences (PaP-eRs. This heuristic reduced the complexity of teaching in a manageable story located in a specific context, so that teachers could identify and reflect on their theories about the teaching and learning of chemistry. This study showed that teachers in training identified and developed the following elements of the CTPC of chemistry: general pedagogy, language as a learning tool, difficulties and alternative conceptions, knowledge of technology as an instrument to represent the contents and manage the chemistry classroom, and the formative evaluation. Definitely, the reflection of the critical events of the PaP-eRs and videos of cases was considered an appropriate heuristic that allowed the future teachers to articulate the knowledge coming from the literature in education in chemistry, with the virtual experiences of teaching-learning of a real context. Of course, this reflection was mediated by reading, discussing and reflecting on the intelligent actions of an exemplary teacher when guiding singular students from a sociocultural perspective, with the purpose of beginning to refine their theories of teaching and learning chemistry.

  8. Insights for conducting real-time focus groups online using a web conferencing service [version 2; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    James Kite

    2017-06-01

    Full Text Available Background: Online focus groups have been increasing in use over the last 2 decades, including in biomedical and health-related research. However, most of this research has made use of text-based services such as email, discussion boards, and chat rooms that do not replicate the experience of face-to-face focus groups. Web conferencing services have the potential to more closely match the face-to-face focus group experience, including important visual and aural cues. This paper provides critical reflections on using a web conferencing service to conduct online focus groups. Methods: We conducted both online and face-to-face focus groups as part of the same study. The online groups were conducted in real-time using the web conferencing service, Blackboard Collaborate TM. We used reflective practice to assess the similarities and differences in the conduct and content of the groups across the two platforms. Results: We found that further research using such services is warranted, particularly when working with hard-to-reach or geographically dispersed populations. The level of discussion and the quality of the data obtained was similar to that found in face-to-face groups. However, some issues remain, particularly in relation to managing technical issues experienced by participants and ensuring adequate recording quality to facilitate transcription and analysis. Conclusions: Our experience with using web conferencing for online focus groups suggests that they have the potential to offer a realistic and comparable alternative to face-to-face focus groups, especially for geographically dispersed populations such as rural and remote health practitioners. Further testing of these services is warranted but researchers should carefully consider the service they use to minimise the impact of technical difficulties.

    2015-01-01

    Use of video games as a leisure-time activity has increased among teenagers. Excessive use of video games is associated with psychosocial dysfunctions in the user's life. Two teenagers came for consultation to our Service for Healthy Use of Technology (SHUT) clinic for management of addiction due to video games. They were assessed using a clinical interview as well as the General Health Questionnaire and Griffith criteria for video games. The cases emphasize the addictive potential of video games and their association with lifestyle changes. Addiction to video games has implications for screening and intervention among teenagers.

    Harris, M A; Hood, K K; Mulvaney, S A

    2012-11-01

    A variety of innovative technologies are available to assist with the management of diabetes in teenagers. Technologies include devices that assist with the direct day-to-day management of diabetes including insulin pumps and continuous glucose monitors. These devices are being used more and more with teenagers as a means of improving treatment adherence and glycaemic control. In addition, telehealth is being used to deliver care and support around diabetes management issues for teens with diabetes. Telehealth used in diabetes care for teens includes cell phones and video-conferencing. The goal of this telehealth technology is to support health behaviours and implement behavioural change strategies in a way that is more integrated into the everyday lives of patients and even in the context in which the behaviours occur in 'real time'. Finally, information and support via the Internet are gaining acceptance and use among teens with diabetes as an effective means of strategies for improved diabetes self-care. All three of these broad uses of technology in diabetes in teens represent flexible, innovative, and accessible approaches to improving both diabetes management and glycaemic control in this 'at risk' population. © 2012 Blackwell Publishing Ltd.

    2018-01-01

    Use/abuse of Information and Communications Technologies (ICT) has in recent years become a topic of great interest. Current discussion addresses whether it must be considered addictive behaviour and if it is a problem that primarily affects adolescents and youth. This study aims to understand the problems that affect people of all ages in controlling the use of these ICTs and whether they are related to mental health problems, stress and difficulties in executive control of behaviour. A survey was administered through social networks and email, using the MULTICAGE-ICT, a questionnaire that explores problems in the use of Internet, mobile phones, video games, instant messaging and social networks. Additionally, the Prefrontal Symptom Inventory, General Health Questionnaire and Perceived Stress Scale were administered. The sample was comprised of 1,276 individuals of all ages from different Spanish-speaking countries. The results indicate that about 50% of the sample, regardless of age or other variables, presents significant problems with the use of these technologies, and that these problems are directly related to symptoms of poor prefrontal functioning, stress and mental health problems. The results reveal the need for reconsidering whether we are facing an addictive behaviour or a new problem demanding environmental, psychological, sociological and sociopolitical explanations; therefore, it is necessary to reformulate actions to be implemented to address and refocus our understanding of the problem.

  14. RODOS and decision conferencing on early phase protective actions in Finland

    1998-12-01

    This work was undertaken in order to study the utilisation of decision conferencing and of the RODOS system when considering early phase protective actions in the case of a nuclear accident. Altogether four meetings with various people were organised. The meetings were attended by competent national safety authorities and technical level decision-makers, i.e., those who are responsible for preparing advice or making presentations of matters for decision-makers responsible for practical implementation of actions. In the first set of meetings the aim was to elicit the factors/attributes that have to be considered when making a decision on sheltering, evacuation and iodine tablets. No uncertainties nor a threat phase were considered but everything was assumed to happen as described in the given scenario. The theme in the second set of meetings was to study the implications of probabilities. All information was calculated with the support of the RODOS system. In the early phases of a nuclear accident time is limited. Prestructured generic value trees or a list of possible attributes can help to save time. A possible approach is to present a large generic value tree. Either the decision-makers select the attributes that are suitable for the case in hand or the facilitator offers a choice between more structured value trees. The decision-makers then just examine the suggested value trees, check the generic tree to make sure that no important factors have been omitted and choose the appropriate one. As in previous RODOS exercises, the participants felt that RODOS could be used for providing information but found it more problematic to use decision analysis methods when deciding on countermeasures in the early phase of a nuclear accident. Furthermore, it was noted that understanding the actual meaning of `soft` attributes, such as socio-psychological impacts or political cost, was not a straightforward issue. Consequently, the definition of attributes in advance would be

    This study aimed to determine the feasibility of patient-initiated online Internet urgent care visits, and to describe patient characteristics, scope of care, provider adherence to protocols, and diagnostic and therapeutic utilization. A total of 456 unique patients were seen via Internet-based technology during the study period, generating 478 consecutive total patient visits. Of the 82 patients referred for an in-person evaluation, 75 patients (91.5%) reported to the clinic as instructed. None of the 82 patients recommended for in-person evaluation required an emergency department referral, hospital admission or urgent consultative referral. We conclude that real-time online primary and urgent care visits are feasible, safe and potentially beneficial in increasing convenient access to urgent and primary care. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    This article reports the outcome evaluation findings of an experimental study conducted with families in the child welfare system in Florida. Families were randomly assigned to one of three Family Team Conferencing (FTC) models. In Pathway 1, the comparison model, FTCs were facilitated by case-workers. In Pathway 2, one of two experimental models, FTCs were cofacilitated by caseworkers and a designated/trained facilitator, and included expedited family engagement as well as the provision of FTCs throughout the life of a case. Pathway 3, also an experimental model, had the same components of Pathway 2 but also included family alone time. In approximately three years of the project period, 623 families agreed to participate in the study. Study findings showed no statistically significant change observed for families participating in Pathway 1 FTCs in terms of protective factors, achieving family-defined service and plan-of-care goals, and emotional and behavioral symptomology of children. Cases in Pathway 2 demonstrated significant improvement in family functioning and resiliency, nurturing and attachment, and increasing parents' knowledge about "what to do as a parent." Caregivers and teens in Pathway 3 reported significant improvement in expression of emotional symptomology/problems, conduct problems, hyperactivity, peer problems, and a measure of total difficulties. However, foster care re-entry rates were significantly higher for Pathway 3 than Pathway 2 (but not Pathway 1). Moreover, Pathway 2 and Pathway 3 FTCs had a significant effect on moving the family toward agreed upon service goals. Taken together, these findings suggest that the experimental FTC models in which facilitators were used and family engagement was expedited and sustained through subsequent FTCs demonstrated moderate, yet mixed benefits to children, youth, and families.

    The current mobile-handset market is a vital and growing one, being driven by technology advances, including increased bandwidth and processing performance, as well as reduced power consumption and improved screen technologies. The 3G/4G handsets of today are multimedia internet devices with increased screen size, HD video and gaming, interactive touch screens, HD camera and camcorders, as well as incredible social, entertainment, and productivity applications. While mobile-technology advancements to date have made us more social in many ways, new advancements over the next decade will bring us to the next level, allowing mobile users to experience new types of "virtual" social interactions with all the senses. The mobile handsets of the future will be smart autonomous-lifestyle devices with a multitude of incorporated sensors, applications and display options, all designed to make your life easier and more productive! With future display media, including 3D imaging, virtual interaction and conferencing will be possible, making every call feel like you are in the same room, providing an experience far beyond today's video conferencing technology. 3D touch-screen with integrated image-projection technologies will work in conjunction with gesturing to bring a new era of intuitive mobile device applications, interaction, and information sharing. Looking to the future, there are many challenges to be faced in delivering a smart mobile companion device that will meet the user demands. One demand will be for the availability of new and compelling services, and features on the "mobile companion". These mobile companions will be more than just Internet devices, and will function as on-the-go workstations, allowing users to function as if they were sitting in front of their computer in the office or at home. The massive amounts of data that will be transmitted through, to and from these mobile companions will require immense improvements in system performance, including

  10. Video consultation use by Australian general practitioners: video vignette study.

    Jiwa, Moyez; Meng, Xingqiong

    2013-06-19

    There is unequal access to health care in Australia, particularly for the one-third of the population living in remote and rural areas. Video consultations delivered via the Internet present an opportunity to provide medical services to those who are underserviced, but this is not currently routine practice in Australia. There are advantages and shortcomings to using video consultations for diagnosis, and general practitioners (GPs) have varying opinions regarding their efficacy. The aim of this Internet-based study was to explore the attitudes of Australian GPs toward video consultation by using a range of patient scenarios presenting different clinical problems. Overall, 102 GPs were invited to view 6 video vignettes featuring patients presenting with acute and chronic illnesses. For each vignette, they were asked to offer a differential diagnosis and to complete a survey based on the theory of planned behavior documenting their views on the value of a video consultation. A total of 47 GPs participated in the study. The participants were younger than Australian GPs based on national data, and more likely to be working in a larger practice. Most participants (72%-100%) agreed on the differential diagnosis in all video scenarios. Approximately one-third of the study participants were positive about video consultations, one-third were ambivalent, and one-third were against them. In all, 91% opposed conducting a video consultation for the patient with symptoms of an acute myocardial infarction. Inability to examine the patient was most frequently cited as the reason for not conducting a video consultation. Australian GPs who were favorably inclined toward video consultations were more likely to work in larger practices, and were more established GPs, especially in rural areas. The survey results also suggest that the deployment of video technology will need to focus on follow-up consultations. Patients with minor self-limiting illnesses and those with medical

    Video-On-Demand is a new development on the Internet. In order to manage the rich multimedia information and the large number of users, we present an Internet Video-On-Demand system with some E- Commerce flavors. This paper presents the system architecture and technologies required in the implementation. It provides interactive Video-On-Demand services in which the user has a complete control over the session presentation. It allows the user to select and receive specific video information by retrieving the database. For improving the performance of video information retrieval and management, the video information is represented by hierarchical video metadata in XML format. Video metadatabase stored the video information in this hierarchical structure and allows user to search the video shots at different semantic levels in the database. To browse the searched video, the user not only has full-function VCR capabilities as the traditional Video-On-Demand, but also can browse the video in a hierarchical method to view different shots. In order to perform management of large number of users over the Internet, a membership database designed and managed in an E-Commerce environment, which allows the user to access the video database based on different access levels.

    4K video is a new format. At 3840 × 2160 resolution, it has 4 times the resolution of standard 1080 high definition (HD) video. Magnification can be done without loss of resolution. This study uses 4K video for video-stroboscopy. Forty-six patients were examined by conventional video-stroboscopy (digital 3 chip CCD) and compared with 4K video-stroboscopy. The video was recorded on a Blackmagic 4K cinema production camera in CinemaDNG RAW format. The video was played back on a 4K monitor and compared to standard video. Pathological conditions included: polyps, scar, cysts, cancer, sulcus, and nodules. Successful 4K video recordings were achieved in all subjects using a 70° rigid endoscope. The camera system is bulky. The examination is performed similarly to standard video-stroboscopy. Playback requires a 4K monitor. As expected, the images were far clearer in detail than standard video. Stroboscopy video using the 4K camera was consistently able to show more detail. Two patients had diagnosis change after 4K viewing. 4K video is an exciting new technology that can be applied to laryngoscopy. It allows for cinematic 4K quality recordings. Both continuous and stroboscopic light can be used for visualization. Its clinical utility is feasible, but usefulness must be proven. © The Author(s) 2015.

    India has made appreciable progress and continues to demonstrate a strong commitment for establishing and operating a disease surveillance programme responsive to the requirements of the International Health Regulations (IHR[2005]). Within five years of its launch, India has effectively used modern information and communication technology for collection, storage, transmission and management of data related to disease surveillance and effective response. Terrestrial and/or satellite based linkages are being established within all states, districts, state-run medical colleges, infectious disease hospitals, and public health laboratories. This network enables speedy data transfer, video conferencing, training and e-learning for outbreaks and programme monitoring. A 24x7 call centre is in operation to receive disease alerts. To complement these efforts, a media scanning and verification cell functions to receive reports of early warning signals. During the 2009 H1N1 outbreak, the usefulness of the information and communication technology (ICT) network was well appreciated. India is using ICT as part of its Integrated Disease Surveillance Project (IDSP) to help overcome the challenges in further expansion in hard-to-reach populations, to increase the involvement of the private sector, and to increase the use of other modes of communication like e-mail and voicemail.

    Full Text Available Inter-organizational problem solving of emergencies and extreme events are complex research fields where scarce experimental data is available. To address this problem, the Inter-GAP In Vivo System, was developed to run behavioural experiments of complex crisis. The system design and testing included three categories of participants: for pilot testing, first year university students; for theoretical validity, college students engaged in emergency management programs; and for field validity, expert decision makers who managed major crises. A comparative assessment was performed to select the most suitable video conferencing software commercially available, since it was more cost-efficient to acquire a tool already developed and customized it to the experiment needs than it was to design a new one. Software features analyzed were: ease of use, recording capabilities, format delivery options and security. The Inter-GAP In Vivo System setup was implemented on the video conference platform selected. The system performance was evaluated at three levels: technical setup, task design and work flow processes. The actual experimentation showed that the conferencing software is a versatile tool to enhance collaboration between stakeholders from different organizations, due to the audiovisual contact participants can establish, where non verbal cues can be interchanged along the problem solving processes. Potential future system applications include: collaborative and cross – functional training between organizations.

    Research has investigated whether communication technologies (e.g. mobile telephony, forums, email) can be used to transfer digital information between healthcare professionals and young people who live with diabetes. The systematic review evaluates the effectiveness and impact of these technologies on communication. Nine electronic databases were searched. Technologies were described and a narrative synthesis of all studies was undertaken. Of 20,925 publications identified, 19 met the inclusion criteria, with 18 technologies assessed. Five categories of communication technologies were identified: video-and tele-conferencing (n = 2); mobile telephony (n = 3); telephone support (n = 3); novel electronic communication devices for transferring clinical information (n = 10); and web-based discussion boards (n = 1). Ten studies showed a positive improvement in HbA1c following the intervention with four studies reporting detrimental increases in HbA1c levels. In fifteen studies communication technologies increased the frequency of contact between patient and healthcare professional. Findings were inconsistent of an association between improvements in HbA1c and increased contact. Limited evidence was available concerning behavioural and care coordination outcomes, although improvement in quality of life, patient-caregiver interaction, self-care and metabolic transmission were reported for some communication technologies. The breadth of study design and types of technologies reported make the magnitude of benefit and their effects on health difficult to determine. While communication technologies may increase the frequency of contact between patient and health care professional, it remains unclear whether this results in improved outcomes and is often the basis of the intervention itself. Further research is needed to explore the effectiveness and cost effectiveness of increasing the use of communication technologies between young people and healthcare professionals.

    Full Text Available In recent days there is a growing interest in the study of creative writing. A number of approaches for teaching creative writing have also been investigated.  However, studies investigating creative writing particularly for primary school students are hardly to find. The aim of the present research is to figure out how conferencing approach is applied to teach poetry writing and to find out the impact of this approach to the students’ writing skills. The study used a classroom action research with 30 sixth-grade students as the participants. To ensure the present approach effectively improves the learning achievement, the study used three cycles of teaching steps, including classical, group, and individual. Various media and sources to support the learning activities were also used. The results of the study show that there is a significant improvement in students’ writing skills, in which the average score of the third cycle was twice higher than that of the first cycle. This suggests that conferencing instruction had been successful in improving students’ writing skills. The process of interaction, both among students and between students and the teachers, were also emphasized. In addition, the teachers gained an experience of assesing poetry writing analytically using four aspects: creative idea, diction, information, and imagination.

    Video has the ingredients to reach us emotionally - with amazing images, enthusiastic interviews, music, and video game-like animations-- and it's emotion that motivates us to learn more about our new interest. However, watching video is usually passive. New web-based technology is expanding and enhancing the video experience, creating opportunities to use video with more direct interaction. This talk will look at an Educaton and Outreach team's experience producing video-centric curriculum using innovative interactive media tools from TED-Ed and FlixMaster. The Consortium for Ocean Leadership's Deep Earth Academy has partnered with the Center for Dark Energy Biosphere Investigations (C-DEBI) to send educators and a video producer aboard three deep sea research expeditions to the Juan de Fuca plate to install and service sub-seafloor observatories. This collaboration between teachers, students, scientists and media producers has proved a productive confluence, providing new ways of understanding both ground-breaking science and the process of science itself - by experimenting with new ways to use multimedia during ocean-going expeditions and developing curriculum and other projects post-cruise.

  10. Multiview video codec based on KTA techniques

    2011-03-01

    Multi-view video coding (MVC) is a video coding standard developed by MPEG and VCEG for multi-view video. It showed average PSNR gain of 1.5dB compared with view-independent coding by H.264/AVC. However, because resolutions of multi-view video are getting higher for more realistic 3D effect, high performance video codec is needed. MVC adopted hierarchical B-picture structure and inter-view prediction as core techniques. The hierarchical B-picture structure removes the temporal redundancy, and the inter-view prediction reduces the inter-view redundancy by compensated prediction from the reconstructed neighboring views. Nevertheless, MVC has inherent limitation in coding efficiency, because it is based on H.264/AVC. To overcome the limit, an enhanced video codec for multi-view video based on Key Technology Area (KTA) is proposed. KTA is a high efficiency video codec by Video Coding Expert Group (VCEG), and it was carried out for coding efficiency beyond H.264/AVC. The KTA software showed better coding gain than H.264/AVC by using additional coding techniques. The techniques and the inter-view prediction are implemented into the proposed codec, which showed high coding gain compared with the view-independent coding result by KTA. The results presents that the inter-view prediction can achieve higher efficiency in a multi-view video codec based on a high performance video codec such as HEVC.

    Gustafson, Peter C.

    1997-07-01

    For many years, photogrammetry has been in use at TRW. During that time, needs have arisen for highly repetitive measurements. In an effort to satisfy these needs in a timely manner, a specialized Robotic Video Photogrammetry System (RVPS) was developed by TRW in conjunction with outside vendors. The primary application for the RVPS has strict accuracy requirements that demand significantly more images than the previously used film-based system. The time involved in taking these images was prohibitive but by automating the data acquisition process, video techniques became a practical alternative to the more traditional film- based approach. In fact, by applying video techniques, measurement productivity was enhanced significantly. Analysis involved was also brought `on-board' to the RVPS, allowing shop floor acquisition and delivery of results. The RVPS has also been applied in other tasks and was found to make a critical improvement in productivity, allowing many more tests to be run in a shorter time cycle. This paper will discuss the creation of the system and TRW's experiences with the RVPS. Highlighted will be the lessons learned during these efforts and significant attributes of the process not common to the standard application of photogrammetry for industrial measurement. As productivity and ease of use continue to drive the application of photogrammetry in today's manufacturing climate, TRW expects several systems, with technological improvements applied, to be in use in the near future.

    Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character recognition (OCR) technology was enhanced with image transformations for extraction of text from video frames to support indexing and search. The images and text on video frames is analyzed to divide lecture videos into topical segments. The ICS video player integrates indexing, search, and captioning in video playback providing instant access to the content of interest. This video framework has been used by more than 70 courses in a variety of STEM disciplines and assessed by more than 4000 students. Results presented from the surveys demonstrate the value of the videos as a learning resource and the role played by videos in a students learning process. Survey results also establish the value of indexing and search features in a video platform for education. This paper reports on the development and evaluation of ICS videos framework and over 5 years of usage experience in several STEM courses.

    Forms of surveillance are very quickly becoming an integral part of crime control policy, crisis management, social control theory and community consciousness. In turn, it has been used as a simple and effective solution to many of these problems. However, privacy-related concerns have been expressed over the development and deployment of this technology. Used properly, video cameras help expose wrongdoing but typically come at the cost of privacy to those not involved in any maleficent activity. This work describes the design and implementation of a real-time, privacy-protecting video surveillance infrastructure that fuses additional sensor information (e.g. Radio-frequency Identification) with video streams and an access control framework in order to make decisions about how and when to display the individuals under surveillance. This video surveillance system is a particular instance of a more general paradigm of privacy-protecting data collection. In this paper we describe in detail the video processing techniques used in order to achieve real-time tracking of users in pervasive spaces while utilizing the additional sensor data provided by various instrumented sensors. In particular, we discuss background modeling techniques, object tracking and implementation techniques that pertain to the overall development of this system.

    1999-07-01

    In July 1996 the Arizona Telemedicine Program (ATP) was initiated by the state legislature in recognition of the needs of under-served populations in the state. Two important goals are: establish a statewide telemedicine network infrastructure; and use that infrastructure as a test bed to evaluate the effectiveness of state-of-the-art telemedicine services. These two goals exist in the context of an integrated, multidisciplinary telemedicine program. It is necessary to accommodate distinct levels of connectivity for sites depending on their association with the program and the corresponding level of services to be provided. For remote client sites requiring the highest level of service were selected the use of dedicated T1 circuits. At these sites the capabilities provided include: PC based store-and- forward services; point-to-point interactive real-time video interactions for clinical encounters; and multi-point interactive real-time video interactions for support groups and educational activities. For sites funded for lower levels of service we selected simple dial-up telephone based communications to support store-and-forward activities and inexpensive telephone based video conferencing equipment for administrative interactions. At the service sites distributed within the Arizona Health Sciences Center (AHSC) we selected standard LAN technology for store-and-forward applications and T1 based services for interactive video. To integrate these services we selected the Asynchronous Transfer Mode (ATM) protocol, integrated with the LAN environment within the AHSC. The integrated telemedicine network supports eight client sites and two service sites with T1-based ATM and four sites with dial-up lines. At the AHSC, ATM and LAN infrastructure is distributed to several clinical areas, allowing physicians to support telemedicine activities where they normally work. Between July 1997 and Jan 1999 over 2000 telemedicine sessions have been performed, nearly 50 percent of

    1995-12-01

    The video coding and distribution approach presented in this paper has two key characteristics that make it ideal for integration of video communication services over common broadband digital networks. The modular multi-resolution nature of the coding scheme provides the necessary flexibility to accommodate future advances in video technology as well as robust distribution over various network environments. This paper will present an efficient and scalable coding scheme for video communications. The scheme is capable of encoding and decoding video signals in a hierarchical, multilayer fashion to provide video at differing quality grades. Subsequently, the utilization of this approach to enable efficient bandwidth sharing and robust distribution of video signals in multipoint communications is presented. Coding and distribution architectures are discussed which include multi-party communications in a multi-window fashion within ATM environments. Furthermore, under the limited capabilities typical of wideband/broadband access networks, this architecture accommodates important video-based service applications such as Interactive Distance Learning.

    As they age, baby boomers (born 1946-1964) will have increasing medical needs and are likely to place large demand on health care resources. Consumer health technologies may help stem rising health care needs and costs by improving provider-to-patient communication, health monitoring, and information access and enabling self-care. Research has not explored the degree to which baby boomers are ready for, or are currently embracing, specific consumer health technologies This study explores how baby boomers' readiness to use various technologies for health purposes compares to other segments of the adult population. The goals of the study are to (1) examine what technologies baby boomers are ready to use for health purposes, (2) investigate barriers to baby boomers' use of technology for health purposes, and (3) understand whether readiness for and barriers to baby boomers' use of consumer health technologies differ from those of other younger and older consumers. Data were collected via a survey offered to a random sample of 3000 subscribers to a large pharmacy benefit management company. Respondents had the option to complete the survey online or by completing a paper-based version of the survey. Data from 469 respondents (response rate 15.63%) were analyzed, including 258 baby boomers (aged 46-64 years), 72 younger (aged 18-45 years), and 139 older (age >64 years) participants. Baby boomers were found to be similar to the younger age group, but significantly more likely than the older age group to be ready to use 5 technologies for health purposes (health information websites, email, automated call centers, medical video conferencing, and texting). Baby boomers were less ready than the younger age group to adopt podcasts, kiosks, smartphones, blogs, and wikis for health care purposes.

  11. The Aesthetics of the Ambient Video Experience

    Directory of Open Access Journals (Sweden)

    Jim Bizzocchi

    2008-01-01

    Full Text Available Ambient Video is an emergent cultural phenomenon, with roots that go deeply into the history of experimental film and video art. Ambient Video, like Brian Eno's ambient music, is video that "must be as easy to ignore as notice" [9]. This minimalist description conceals the formidable aesthetic challenge that faces this new form. Ambient video art works will hang on the walls of our living rooms, corporate offices, and public spaces. They will play in the background of our lives, living video paintings framed by the new generation of elegant, high-resolution flat-panel display units. However, they cannot command attention like a film or television show. They will patiently play in the background of our lives, yet they must always be ready to justify our attention in any given moment. In this capacity, ambient video works need to be equally proficient at rewarding a fleeting glance, a more direct look, or a longer contemplative gaze. This paper connects a series of threads that collectively illuminate the aesthetics of this emergent form: its history as a popular culture phenomenon, its more substantive artistic roots in avant-garde cinema and video art, its relationship to new technologies, the analysis of the viewer's conditions of reception, and the work of current artists who practice within this form.

    Physical activity monitoring algorithms are often developed using conditions that do not represent real-life activities, not developed using the target population, or not labelled to a high enough resolution to capture the true detail of human movement. We have designed a semi-structured supervised laboratory-based activity protocol and an unsupervised free-living activity protocol and recorded 20 older adults performing both protocols while wearing up to 12 body-worn sensors. Subjects' movements were recorded using synchronised cameras (≥25 fps), both deployed in a laboratory environment to capture the in-lab portion of the protocol and a body-worn camera for out-of-lab activities. Video labelling of the subjects' movements was performed by five raters using 11 different category labels. The overall level of agreement was high (percentage of agreement >90.05%, and Cohen's Kappa, corrected kappa, Krippendorff's alpha and Fleiss' kappa >0.86). A total of 43.92 h of activities were recorded, including 9.52 h of in-lab and 34.41 h of out-of-lab activities. A total of 88.37% and 152.01% of planned transitions were recorded during the in-lab and out-of-lab scenarios, respectively. This study has produced the most detailed dataset to date of inertial sensor data, synchronised with high frame-rate (≥25 fps) video labelled data recorded in a free-living environment from older adults living independently. This dataset is suitable for validation of existing activity classification systems and development of new activity classification algorithms.

    Anguera, Joaquin A; Gunning, Faith M; Areán, Patricia A

    2017-06-01

    Existing treatments for depression are known to have only modest effects, are insufficiently targeted, and are inconsistently utilized, particularly in older adults. Indeed, older adults with impaired cognitive control networks tend to demonstrate poor response to a majority of existing depression interventions. Cognitive control interventions delivered using entertainment software have the potential to not only target the underlying cerebral dysfunction associated with depression, but to do so in a manner that is engaging and engenders adherence to treatment protocol. In this proof-of-concept trial (Clinicaltrials.gov #: NCT02229188), individuals with late life depression (LLD) (22; 60+ years old) were randomized to either problem solving therapy (PST, n = 10) or a neurobiologically inspired digital platform designed to enhance cognitive control faculties (Project: EVO™, n = 12). Given the overlapping functional neuroanatomy of mood disturbances and executive dysfunction, we explored the impact of an intervention targeting cognitive control abilities, functional disability, and mood in older adults suffering from LLD, and how those outcomes compare to a therapeutic gold standard. EVO participants demonstrated similar improvements in mood and self-reported function after 4 weeks of treatment to PST participants. The EVO participants also showed generalization to untrained measures of working memory and attention, as well as negativity bias, a finding not evident in the PST condition. Individuals assigned to EVO demonstrated 100% adherence. This study provides preliminary findings that this therapeutic video game targeting cognitive control deficits may be an efficacious LLD intervention. Future research is needed to confirm these findings. © 2016 Wiley Periodicals, Inc.

    2006-07-01

    Video stabilization is an important video enhancement technology which aims at removing annoying shaky motion from videos. We propose a practical and robust approach of video stabilization that produces full-frame stabilized videos with good visual quality. While most previous methods end up with producing smaller size stabilized videos, our completion method can produce full-frame videos by naturally filling in missing image parts by locally aligning image data of neighboring frames. To achieve this, motion inpainting is proposed to enforce spatial and temporal consistency of the completion in both static and dynamic image areas. In addition, image quality in the stabilized video is enhanced with a new practical deblurring algorithm. Instead of estimating point spread functions, our method transfers and interpolates sharper image pixels of neighboring frames to increase the sharpness of the frame. The proposed video completion and deblurring methods enabled us to develop a complete video stabilizer which can naturally keep the original image quality in the stabilized videos. The effectiveness of our method is confirmed by extensive experiments over a wide variety of videos.

    2011-01-01

    Abstract Objective: To test the feasibility of using cell phone technology to provide video medical interpretation services at a distance. Materials and Methods: Alternative cell phone services were researched and videoconferencing technologies were tried out to identify video products and telecommunication services needed to meet video medical interpretation requirements. The video and telecommunication technologies were tried out in a pharmacy setting and compared with use of the telephone. Results: Outcomes were similar to findings in previous research involving video medical interpretation with higher bandwidth and video quality. Patients appreciated the interpretation service no matter how it is provided, while health providers and interpreters preferred video. Conclusion: It is possible to provide video medical interpretation services via cellular communication using lower bandwidth videoconferencing technology that provides sufficient quality, at least in pharmacy settings. However, a number of issues need to be addressed to ensure quality of service. PMID:22011055

    1999-01-01

    Current video transmission and distribution systems at CERN use a variety of analogue techniques which are several decades old. It will soon be necessary to replace this obsolete equipment, and the opportunity therefore exists to rationalize the diverse systems now in place. New standards for digital transmission and distribution are now emerging. This paper gives an overview of these new standards and of the underlying technology common to many of them. The paper reviews Digital Video Broadcasting (DVB), the Motion Picture Experts Group specifications (MPEG1, MPEG2, MPEG4, and MPEG7), videoconferencing standards (H.261 etc.), and packet video systems, together with predictions of the penetration of these standards into the consumer market. The digital transport mechanisms now available (IP, SDH, ATM) are also reviewed, and the implication of widespread adoption of these systems on video transmission and distribution is analysed.

    YouTube is usually considered an entertainment medium to watch cats, gaming, and music videos. But educational channels have been gaining momentum on the platform, some garnering millions of subscribers and billions of views. The Physics Girl YouTube channel is an educational series with PBS Digital Studios created by Dianna Cowern. Using Physics Girl as an example, this talk will examine what it takes to start a short-form educational video series, including logistics and resources. One benefit of video is that every failure is documented on camera and can, and will, be used in this talk as a learning tool. We will look at the channels demographical reach, discuss best practices for effective physics outreach, and survey how online media and technology can facilitate good and bad learning. The aim of this talk is to show how videos are a unique way to share science and enrich the learning experience, in and out of a classroom.

    1996-01-01

    In the past, it has not been possible to "teach oneself to read" at home, because learners could not read the books to teach them. Videos and interactive compact discs have changed that situation and challenge current assumptions of the pedagogy of literacy. This article describes an experimental adult literacy project using video technology. The language used is English, but the basic concepts apply to any alphabetic or syllabic writing system. A half-hour cartoon video can help adults and adolescents with learning difficulties. Computer-animated cartoon graphics are attractive to look at, and simplify complex material in a clear, lively way. This video technique is also proving useful for distance learners, children, and learners of English as a second language. Methods and principles are to be extended using interactive compact discs.

    Wade, P.; Courtney, A. R.

    2013-12-01

    In science, the use of digital video to document phenomena, experiments and demonstrations has rapidly increased during the last decade. The use of digital video for science education also has become common with the wide availability of video over the internet. However, as with using any technology as a teaching tool, some questions should be asked: What science is being learned from watching a YouTube clip of a volcanic eruption or an informational video on hydroelectric power generation? What are student preferences (e.g. multimedia versus traditional mode of delivery) with regard to their learning? This study describes 1) the efficacy of watching digital video in the science classroom to enhance student learning, 2) student preferences of instruction with regard to multimedia versus traditional delivery modes, and 3) the use of creating digital video as a project-based educational strategy to enhance learning. Undergraduate non-science majors were the primary focus group in this study. Students were asked to view video segments and respond to a survey focused on what they learned from the segments. Additionally, they were asked about their preference for instruction (e.g. text only, lecture-PowerPoint style delivery, or multimedia-video). A majority of students indicated that well-made video, accompanied with scientific explanations or demonstration of the phenomena was most useful and preferred over text-only or lecture instruction for learning scientific information while video-only delivery with little or no explanation was deemed not very useful in learning science concepts. The use of student generated video projects as learning vehicles for the creators and other class members as viewers also will be discussed.

    Lin, Shih-Yin; Seaton, Daniel T; Douglas, Scott S; Greco, Edwin F; Thoms, Brian D; Schatz, Michael F

    2016-01-01

    The advent of MOOCs has stimulated interest in using online videos to deliver content in university courses. We examined student engagement with 78 online videos that we created and were incorporated into a one-semester blended introductory mechanics course at the Georgia Institute of Technology. We found that students were more engaged with videos that supported laboratory activities than with videos that presented lecture content. In particular, the percentage of students accessing laboratory videos was consistently greater than 80 percent throughout the semester while the percentage of students accessing lecture videos dropped to less than 40 percent by the end of the term. Moreover, students were more likely to access the entirety of a laboratory video than a lecture video. Our results suggest that students may access videos based on perceived value: students appear to consider the laboratory videos as essential for successfully completing the laboratories while students appear to consider the lecture vid...

  12. Enhanced Video Surveillance (EVS) with speckle imaging

    Energy Technology Data Exchange (ETDEWEB)

    Carrano, C J

    2004-01-13

    Enhanced Video Surveillance (EVS) with Speckle Imaging is a high-resolution imaging system that substantially improves resolution and contrast in images acquired over long distances. This technology will increase image resolution up to an order of magnitude or greater for video surveillance systems. The system's hardware components are all commercially available and consist of a telescope or large-aperture lens assembly, a high-performance digital camera, and a personal computer. The system's software, developed at LLNL, extends standard speckle-image-processing methods (used in the astronomical community) to solve the atmospheric blurring problem associated with imaging over medium to long distances (hundreds of meters to tens of kilometers) through horizontal or slant-path turbulence. This novel imaging technology will not only enhance national security but also will benefit law enforcement, security contractors, and any private or public entity that uses video surveillance to protect their assets.

    Hsu, Charles; Szu, Harold

    2016-05-01

    An intelligent video surveillance system is able to detect and identify abnormal and alarming situations by analyzing object movement. The Smart Sensing Surveillance Video (S3V) System is proposed to minimize video processing and transmission, thus allowing a fixed number of cameras to be connected on the system, and making it suitable for its applications in remote battlefield, tactical, and civilian applications including border surveillance, special force operations, airfield protection, perimeter and building protection, and etc. The S3V System would be more effective if equipped with visual understanding capabilities to detect, analyze, and recognize objects, track motions, and predict intentions. In addition, alarm detection is performed on the basis of parameters of the moving objects and their trajectories, and is performed using semantic reasoning and ontologies. The S3V System capabilities and technologies have great potential for both military and civilian applications, enabling highly effective security support tools for improving surveillance activities in densely crowded environments. It would be directly applicable to solutions for emergency response personnel, law enforcement, and other homeland security missions, as well as in applications requiring the interoperation of sensor networks with handheld or body-worn interface devices.

  7. Social video content delivery

    CERN Document Server

    Wang, Zhi; Zhu, Wenwu

    2016-01-01

    This brief presents new architecture and strategies for distribution of social video content. A primary framework for socially-aware video delivery and a thorough overview of the possible approaches is provided. The book identifies the unique characteristics of socially-aware video access and social content propagation, revealing the design and integration of individual modules that are aimed at enhancing user experience in the social network context. The change in video content generation, propagation, and consumption for online social networks, has significantly challenged the traditional video delivery paradigm. Given the massive amount of user-generated content shared in online social networks, users are now engaged as active participants in the social ecosystem rather than as passive receivers of media content. This revolution is being driven further by the deep penetration of 3G/4G wireless networks and smart mobile devices that are seamlessly integrated with online social networking and media-sharing s...

  13. How Online Access Changed Amateur Video Editing

    Directory of Open Access Journals (Sweden)

    Eugster Benjamin

    2014-12-01

    Full Text Available Digital technology has often been discussed in relation to how it changed either the production or the reception of audiovisual cultures. This paper will consider a combination of both as a crucial part in understanding strategies of inter- and transmedial amateur creativity. Based on an experimental ethnography of the online video subgenre/subculture “YouTubePoop,” the paper will elaborate on the connection between the individual experience and the creation of digital media. The loose collective of independent amateurs behind the YouTubePoop videos makes use of already existing audiovisual material ranging from television shows to videos of other YouTube users. The re-created remixes and mash-ups are characterized by their random selection of original material and their nonsensical humour. Hence, the rapid montage of this heterogeneous content is just as much part of the intensified aesthetic expressiveness as are the applied special effects available in the digital video editing software. Both aspects highlight the strong interdependence of the rapid accessibility of online content and digital technology and the new aesthetic expressions they are fostering. The paper will show how the experience and navigation of digital interfaces (editing software, media players, or homepages affect the design and practice of these video-remixes. This will open the discussion about intertextual strategies of media appropriation to an aesthetic and praxeological analysis of media interaction.

    2017-10-01

    Palliative care for nursing home residents with advanced dementia is often sub-optimal due to poor communication and limited care planning. In a cluster randomized controlled trial, registered nurses (RNs) from 10 nursing homes were trained and funded to work as Palliative Care Planning Coordinators (PCPCs) to organize family case conferences and mentor staff. This qualitative sub-study aimed to explore PCPC and health professional perceptions of the benefits of facilitated case conferencing and identify factors influencing implementation. Semi-structured interviews were conducted with the RNs in the PCPC role, other members of nursing home staff, and physicians who participated in case conferences. Analysis was conducted by two researchers using a thematic framework approach. Interviews were conducted with 11 PCPCs, 18 other nurses, eight allied health workers, and three physicians. Perceived benefits of facilitated case conferencing included better communication between staff and families, greater multi-disciplinary involvement in case conferences and care planning, and improved staff attitudes and capabilities for dementia palliative care. Key factors influencing implementation included: staffing levels and time; support from management, staff and physicians; and positive family feedback. The facilitated approach explored in this study addressed known barriers to case conferencing. However, current business models in the sector make it difficult for case conferencing to receive the required levels of nursing qualification, training, and time. A collaborative nursing home culture and ongoing relationships with health professionals are also prerequisites for success. Further studies should document resident and family perceptions to harness consumer advocacy.
