The number is increasing of broadcasting stations who use HDTV (high-definition television) signals for program formulation for the improvement of video quality for general broadcasting programs. The above-named unit, which transmits HDTV signals which are broadcasting materials over a long distance with their high quality well preserved, is capable of the optical transmission of SDI (serial digital interface) signals meeting the standards of BTA (Broadcasting Technologies Association) on 1 video channel and 2 digital audio channels. It can also work on the light wavelength multiplex system. It was developed under the guidance of TTNet (Tokyo Telecommunication Network Co., Inc.), and gained public favor when it successfully transmitted programs over a distance of approximately 400km from Nagano to Tokyo during the Nagano Olympic Games. It now transmits various high-quality video signals for instance in the relay of baseball games, thereby contributing to the improvement of video quality for broadcasting. (translated by NEDO)

Designing an educative curriculum unit for teaching molecular geometry in high school chemistry

Science.gov (United States)

Makarious, Nader N.

Chemistry is a highly abstract discipline that is taught and learned with the aid of various models. Among the most challenging, yet a fundamental topic in general chemistry at the high school level, is molecular geometry. This study focused on developing exemplary educative curriculum materials pertaining to the topic of molecular geometry. The methodology used in this study consisted of several steps. First, a diverse set of models were analyzed to determine to what extent each model serves its purpose in teaching molecular geometry. Second, a number of high school teachers and college chemistry professors were asked to share their experiences on using models in teaching molecular geometry through an online questionnaire. Third, findings from the comparative analysis of models, teachers’ experiences, literature review on models and students’ misconceptions, the curriculum expectations of the Next Generation Science Standards and their emphasis on three-dimensional learning and nature of science (NOS) contributed to the development of the molecular geometry unit. Fourth, the developed unit was reviewed by fellow teachers and doctoral-level science education experts and was revised to further improve its coherence and clarity in support of teaching and learning of the molecular geometry concepts. The produced educative curriculum materials focus on the scientific practice of developing and using models as promoted in the Next Generations Science Standards (NGSS) while also addressing nature of science (NOS) goals. The educative features of the newly developed unit support teachers’ pedagogical knowledge (PK) and pedagogical content knowledge (PCK). The unit includes an overview, teacher’s guide, and eight detailed lesson plans with inquiry oriented modeling activities replete with models and suggestions for teachers, as well as formative and summative assessment tasks. The unit design process serves as a model for redesigning other instructional units in

Employing Inquiry-Based Computer Simulations and Embedded Scientist Videos To Teach Challenging Climate Change and Nature of Science Concepts

Science.gov (United States)

Cohen, E.

2013-12-01

Design based research was utilized to investigate how students use a greenhouse effect simulation in order to derive best learning practices. During this process, students recognized the authentic scientific process involving computer simulations. The simulation used is embedded within an inquiry-based technology-mediated science curriculum known as Web-based Inquiry Science Environment (WISE). For this research, students from a suburban, diverse, middle school setting use the simulations as part of a two week-long class unit on climate change. A pilot study was conducted during phase one of the research that informed phase two, which encompasses the dissertation. During the pilot study, as students worked through the simulation, evidence of shifts in student motivation, understanding of science content, and ideas about the nature of science became present using a combination of student interviews, focus groups, and students' conversations. Outcomes of the pilot study included improvements to the pedagogical approach. Allowing students to do 'Extreme Testing' (e.g., making the world as hot or cold as possible) and increasing the time for free exploration of the simulation are improvements made as a result of the findings of the pilot study. In the dissertation (phase two of the research design) these findings were implemented in a new curriculum scaled for 85 new students from the same school during the next school year. The modifications included new components implementing simulations as an assessment tool for all students and embedded modeling tools. All students were asked to build pre and post models, however due to technological constraints these were not an effective tool. A non-video group of 44 students was established and another group of 41 video students had a WISE curriculum which included twelve minutes of scientists' conversational videos referencing explicit aspects on the nature of science, specifically the use of models and simulations in science

The orientation of talents cultivation for local colleges is to train engineering application-oriented talents, so the exploration and practice on teaching reform of theory curriculum was carried out. We restructured the knowledge units basing on numerical solution problems, and chose the software to build algorithm models for improving the analytical and designed ability. Relying on micro video lessons platform, the teacher-student interaction was expanded from class to outside. Also, we programmed new experimental homework, which was suited for process evaluation. The new teaching mode has achieved good effect, and the students' application ability was significantly improved.

Investigating the role of educative curriculum materials in supporting teacher enactment of a field-based urban ecology investigation

Science.gov (United States)

Houle, Meredith

2008-10-01

This multiple case study examined how three urban science teachers used curriculum materials designed educatively. Educative curriculum materials have been suggested as one way to support science teacher learning, particularly around new innovations and new pedagogies and to support teachers in evaluating and modifying materials to meet the needs of their students (Davis & Krajcik, 2005). While not a substitute for professional development, educative curriculum materials may provide an opportunity to support teachers' enactment and learning in the classroom context (Davis & Krajcik, 2005; Remillard, 2005; Schneider & Krajcik, 2002). However, little work has examined how science teachers interact with written curriculum materials to design classroom instruction. Grounded in sociocultural analysis, this study takes the theoretical stance that teachers and curriculum materials are engaged in a dynamic and participatory relationship from which the planned and enacted curriculum emerges (Remillard, 2005). Teaching is therefore a design activity where teachers rely on their personal resources and the curricular resources to construct and shape their students' learning experiences (Brown, 2002). Specifically this study examines how teacher beliefs influence their reading and use of curriculum and how educative features in the written curriculum inform teachers' pedagogical decisions. Data sources included classroom observation and video, teacher interviews, and classroom artifacts. To make sense how teachers' make curricular decisions, video were analyzed using Brown's (2002) Pedagogical Design for Enactment Framework. These coded units were examined in light of the teacher interviews, classroom notes and artifacts to examine how teachers' beliefs influenced these decisions. Data sources were then reexamined for evidence of teachers' use of specific educative features. My analyses revealed that teachers' beliefs about curriculum influenced the degree to which teachers

Boscoe, Elizabeth F; Cabrera-Muffly, Cristina

2017-02-01

To identify trends in medical school otolaryngology curriculum requirements. Survey of United States allopathic medical schools. A survey was sent to deans of curriculum at allopathic medical schools. We identified opportunities for medical students to learn basic concepts in otolaryngology during their undergraduate medical training. The opportunities were classified into preclinical and clinical as well as elective and mandatory rotations. Of the schools surveyed, 60% responded. Mean class size was 149 students. Sixty-eight percent of surveyed schools noted that 75% to 100% of their students participated in preclinical otolaryngology experiences, with 59% reporting a mandatory preclinical otolaryngology module for all students. Eighty-nine percent of schools offered otolaryngology as a clinical elective rotation, with a mean of 12 students participating yearly. Only 7% of schools required a mandatory otolaryngology clinical rotation. Our data suggest that medical students do not receive sufficient exposure to otolaryngology during medical school. Increased requirements for otolaryngology curriculum may be beneficial to all medical students, regardless of their specialty choice. NA.

The quest for balanced curriculum: The perceptions of secondary students and teachers who experienced an integrated art and science curriculum

Science.gov (United States)

Schramm, Susan Lynn

The purpose of this study was to describe how an integrated high school curriculum unit connecting the different subject areas of art and science could be used to give students a voice in the decisions about learning. Through the data generated I examined the obstacles of integrating curriculum in a traditionally subject-centered high school. Forty-one students, nineteen biology students in the ninth grade, and twenty-two art students ranging from the tenth grade through the twelfth grade, along with their two teachers and a student teacher, were the subjects of the research. An integrated curricular unit, "Genetic Robotics," was designed specifically for this research to enable students to integrate scientific and artistic processes such as communication skills, problem-solving, critical thinking, creativity and responsiveness to the aesthetic; thus empowering them for future learning. Semi-structured interviews, surveys, questionnaires, informal conversations, reaction journals, field observations, video tapes, and official documents from the school, provided the data for this research. Data were collected using a strategy of participant-observation. The constant comparative analysis method was employed to explore emerging themes. Oak Park students' adaptability to an integrated art and science unit was found to be limited because of their inability to conceptualize curricular structures that are different from the traditional ones to which they are accustomed. Students typically scored high on standardized proficiency tests and college entrance exams. Therefore, for them to experience an innovation that is not based on the memorize-and-recall mode of learning is to risk failure and many are unwilling to do so, especially the high achieving students.

We developed a novel curriculum teaching 20 open surgical skills in 5 general domains (instrument handling, knot tying, simple wound closure, advanced wound closure, and hemostasis). The curriculum includes online didactics, skills practice, and defined performance metrics, but is entirely self-guided with no expert oversight or teaching. Subjects included first- and second-year medical students (n = 9). Subjects first viewed a demonstration video depicting proper technique. The pretest was video-recorded performance of each skill. Subjects then completed the self-guided skills curriculum at their own pace, returning for posttesting once they met defined self-assessment criteria. Performance was evaluated through both self-assessment and blinded video review by 2 expert reviewers using previously validated scales. After completion of the curriculum, performance improved significantly by both self-assessment (3,754 ± 1,742 to 6,496 ± 1,337; P performance was significantly better for all domains by self-assessment (P instrument handling). Completion of a self-guided basic surgical skills curriculum allows novice learners to significantly improve performance in basic open surgical skills, without traditional expert teaching. This curriculum is useful for medical students and incoming junior residents. Copyright © 2012 Mosby, Inc. All rights reserved.

Green, Courtney A; Kim, Edward H; O'Sullivan, Patricia S; Chern, Hueylan

2018-01-31

Our previous home-video basic surgical skills curriculum required substantial faculty time and resources, and was limited by delayed feedback and technical difficulties. Consequently, we integrated that curriculum with a mobile application platform. Our purpose is to describe this application and learner satisfaction. The mobile platform incorporates a patented pedagogical design based on Ericsson's deliberate practice and Bandura's social learning theory. Instructors built step-wise skills modules. During the challenge phase, learners watched a video of surgical tasks completed by experts and uploaded a video of themselves performing the same task. In the Peer Review phase, they used a grading rubric to provide feedback. In the Recap stage, learners received individual feedback and could review their own videos. Two groups of learners, graduating medical students and matriculating surgical residents, participated in this independent learning platform, along with 2 to 4 laboratory sessions, and completed a survey about their experience. Survey responses were summarized descriptively and comments analyzed using content analysis. Fifty learners submitted videos of assigned tasks and completed peer reviews. Learners reported positive experiences specifically for the Peer Review Stage, structured home practice, ease of mobile access to submit and review videos, and ongoing immediate feedback. Over half of the learners reported spending at least 10 to 30 minute practicing skills before recording their videos and over 80% rerecorded at least 2 times before submission. Content analysis revealed learners engaged with the educational concepts designed into the platform. Learners easily used and were satisfied with a mobile-technology teaching platform that maintained the fundamental content, educational theories, and organizational structure of our previously effective surgical skills curriculum. Prior challenges were directly addressed through the mobile application's ease

Physical examination (PE) skills among U.S. medical students have been shown to be deficient. This study examines the effect of a Web-based physical examination curriculum on first-year medical student PE skills. Web-based video clips, consisting of instruction in 77 elements of the physical examination, were created using Microsoft Windows Moviemaker software. Medical students' PE skills were evaluated by standardized patients before and after implementation of the Internet-based video. Following implementation of this curriculum, there was a higher level of competency (from 87% in 2002-2003 to 91% in 2004-2005), and poor performances on standardized patient PE exams substantially diminished (from a 14%-22%failure rate in 2002-2003, to 4% in 2004-2005. A significant improvement in first-year medical student performance on the adult PE occurred after implementing Web-based instructional video.

2017-06-01

Increasingly over the past decade, faculty in medical and graduate schools have received requests from digital millennial learners for concise faculty-made educational videos. At our institution, over the past couple of years alone, several hundred educational videos have been created by faculty who teach in a flipped-classroom setting of the pre-clinical medical school curriculum. Despite the appeal and potential learning benefits of digital chalk-talk videos first popularized by Khan Academy, we have observed that the conceptual and technological barriers for creating chalk-talk videos can be high for faculty. To this end, this tips article offers an easy-to-follow 12-step conceptual framework to guide at-home production of chalk-talk educational videos.

2017-11-01

The aim of this study was to study the effect of web-based teaching video packages on medical students' satisfaction during gross anatomy education. The objective was to test the hypothesis that individual preference, which can be related to learning style, influences individual utilization of the video packages developed specifically for the undergraduate medical curriculum. Web-based teaching video packages consisting of Closed Circuit Audiovisual System and Distance Education of Anatomy were prepared. 54 informative application videos each lasting an average 12 min, competent with learning objectives have been prepared. 300 young adults of the medical school on applied anatomy education were evaluated in terms of their course content, exam performance and perceptions. A survey was conducted to determine the difference between the students who did not use teaching packages with those who used it during or after the lecture. A mean of 150 hits for each student per year was indicated. Academic performance of anatomy has been an increase of 10 points. Positive effects of the video packages on anatomy education have manifested on the survey conducted on students. The survey was compiled under twenty different items including effectiveness, providing education opportunity and affecting learning positively. Additionally, the difference was remarkable that the positive ideas of the second year students on learning were statistically significant from that of the third year students. Web-based video packages are helpful, definitive, easily accessible and affordable which enable students with different pace of learning to reach information simultaneously in equal conditions and increase the learning activity in crowded group lectures in cadaver labs. We conclude that personality/learning preferences of individual students influence their use of video packages in the medical curriculum.

Three-directional motion-compensation mask-based novel look-up table on graphics processing units for video-rate generation of digital holographic videos of three-dimensional scenes.

Kwon, Min-Woo; Kim, Seung-Cheol; Kim, Eun-Soo

2016-01-20

A three-directional motion-compensation mask-based novel look-up table method is proposed and implemented on graphics processing units (GPUs) for video-rate generation of digital holographic videos of three-dimensional (3D) scenes. Since the proposed method is designed to be well matched with the software and memory structures of GPUs, the number of compute-unified-device-architecture kernel function calls can be significantly reduced. This results in a great increase of the computational speed of the proposed method, allowing video-rate generation of the computer-generated hologram (CGH) patterns of 3D scenes. Experimental results reveal that the proposed method can generate 39.8 frames of Fresnel CGH patterns with 1920×1080 pixels per second for the test 3D video scenario with 12,088 object points on dual GPU boards of NVIDIA GTX TITANs, and they confirm the feasibility of the proposed method in the practical application fields of electroholographic 3D displays.

2014-01-01

Full Text Available High efficiency video coding (HEVC is the latest video coding standard. HEVC can achieve higher compression performance than previous standards, such as MPEG-4, H.263, and H.264/AVC. However, HEVC requires enormous computational complexity in encoding process due to quadtree structure. In order to reduce the computational burden of HEVC encoder, an early transform unit (TU decision algorithm (ETDA is adopted to pruning the residual quadtree (RQT at early stage based on the number of nonzero DCT coefficients (called NNZ-EDTA to accelerate the encoding process. However, the NNZ-ETDA cannot effectively reduce the computational load for sequences with active motion or rich texture. Therefore, in order to further improve the performance of NNZ-ETDA, we propose an adaptive RQT-depth decision for NNZ-ETDA (called ARD-NNZ-ETDA by exploiting the characteristics of high temporal-spatial correlation that exist in nature video sequences. Simulation results show that the proposed method can achieve time improving ratio (TIR about 61.26%~81.48% when compared to the HEVC test model 8.1 (HM 8.1 with insignificant loss of image quality. Compared with the NNZ-ETDA, the proposed method can further achieve an average TIR about 8.29%~17.92%.

Incorporation of home-video assessments allows flexibility in feedback but requires faculty time. Peer feedback (PF) may provide additional benefits while avoiding these constraints. Twenty-four surgical interns completed a 12-week skills curriculum with home-video assignments focused on knot tying and suturing. Interns were randomized into 2 groups: PF or faculty feedback (FF). Peers and faculty provided feedback on home videos with checklists, global rating, and comments. Learners' skills were assessed at baseline, during, and at the conclusion of the curriculum. Performance of the 2 groups as rated by experts was compared. FF and PF were compared. Both groups improved from baseline, and the highest rated scores were seen on their home-video assessments. The PF group performed better at the final assessment than the FF group (effect size, .84). When using a checklist, there was no significant difference between scores given by peers and faculty. The PF group performed better at the final assessment, suggesting reviewing and analyzing another's performance may improve one's own performance. With checklists as guidance, peers can serve as raters comparable to faculty. Copyright © 2016 Elsevier Inc. All rights reserved.

2017-08-01

"Flipped Classroom" is one of the most popular teaching models, and has been applied in more and more curriculums. It is totally different from the traditional teaching model. In the "Flipped Classroom" model, the students should watch the teaching video afterschool, and in the classroom only the discussion is proceeded to improve the students' comprehension. In this presentation, "Flipped Classroom" was studied and practiced in opto-electronic technology curriculum; its effect was analyzed by comparing it with the traditional teaching model. Based on extensive and deep investigation, the phylogeny, the characters and the important processes of "Flipped Classroom" are studied. The differences between the "Flipped Classroom" and the traditional teaching model are demonstrated. Then "Flipped Classroom" was practiced in opto-electronic technology curriculum. In order to obtain high effectiveness, a lot of teaching resources were prepared, such as the high-quality teaching video, the animations and the virtual experiments, the questions that the students should finish before and discussed in the class, etc. At last, the teaching effect was evaluated through analyzing the result of the examination and the students' surveys.

Investigating the impact of a LEGO(TM)-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines

Science.gov (United States)

Marulcu, Ismail

This mixed method study examined the impact of a LEGO-based, engineering-oriented curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. This study takes a social constructivist theoretical stance that science learning involves learning scientific concepts and their relations to each other. From this perspective, students are active participants, and they construct their conceptual understanding through the guidance of their teacher. With the goal of better understanding the use of engineering education materials in classrooms the National Academy of Engineering and National Research Council in the book "Engineering in K-12 Education" conducted an in-depth review of the potential benefits of including engineering in K--12 schools as (a) improved learning and achievement in science and mathematics, (b) increased awareness of engineering and the work of engineers, (c) understanding of and the ability to engage in engineering design, (d) interest in pursuing engineering as a career, and (e) increased technological literacy (Katehi, Pearson, & Feder, 2009). However, they also noted a lack of reliable data and rigorous research to support these assertions. Data sources included identical written tests and interviews, classroom observations and videos, teacher interviews, and classroom artifacts. To investigate the impact of the design-based simple machines curriculum compared to the scientific inquiry-based simple machines curriculum on student learning outcomes, I compared the control and the experimental groups' scores on the tests and interviews by using ANCOVA. To analyze and characterize the classroom observation videotapes, I used Jordan and Henderson's (1995) method and divide them into episodes. My analyses revealed that the design-based Design a People Mover: Simple Machines unit was, if not better, as successful as the inquiry-based FOSS Levers and Pulleys unit in terms of students' content learning. I also

High-speed three-frame image recording system using colored flash units and low-cost video equipment

Science.gov (United States)

Racca, Roberto G.; Scotten, Larry N.

1995-05-01

This article describes a method that allows the digital recording of sequences of three black and white images at rates of several thousand frames per second using a system consisting of an ordinary CCD camcorder, three flash units with color filters, a PC-based frame grabber board and some additional electronics. The maximum framing rate is determined by the duration of the flashtube emission, and for common photographic flash units lasting about 20 microsecond(s) it can exceed 10,000 frames per second in actual use. The subject under study is strobe- illuminated using a red, a green and a blue flash unit controlled by a special sequencer, and the three images are captured by a color CCD camera on a single video field. Color is used as the distinguishing parameter that allows the overlaid exposures to be resolved. The video output for that particular field will contain three individual scenes, one for each primary color component, which potentially can be resolved with no crosstalk between them. The output is electronically decoded into the primary color channels, frame grabbed and stored into digital memory, yielding three time-resolved images of the subject. A synchronization pulse provided by the flash sequencer triggers the frame grabbing so that the correct video field is acquired. A scheme involving the use of videotape as intermediate storage allows the frame grabbing to be performed using a monochrome video digitizer. Ideally each flash- illuminated scene would be confined to one color channel, but in practice various factors, both optical and electronic, affect color separation. Correction equations have been derived that counteract these effects in the digitized images and minimize 'ghosting' between frames. Once the appropriate coefficients have been established through a calibration procedure that needs to be performed only once for a given configuration of the equipment, the correction process is carried out transparently in software every time a

Using Evolution as a Context for Teaching the Nature of Science to Diverse Student Populations: A High School Unit of Curriculum

Science.gov (United States)

Metcalfe, Angela C.

Teaching evolution provides teachers with the opportunity to educate students on how science aims to understand the natural world. Rooted in research, the purpose of this project was to create NGSS-aligned curriculum focused on teaching the nature of science (NOS) within the context of biological evolution. Field testing and review of the unit resulted in revisions aimed at creating more comprehensive teacher resource materials and explicit inclusion of NOS. Emphasizing NOS in curriculum development and teaching scientific qualities through an evolutionary context has taken the focus off belief or disbelief, keeping the attention on the scientific concept at hand. Designing curriculum around compelling subject matter and embracing student-led learning increased and maintained student interest in the classroom. Implementation of this curriculum not only requires the teacher to be knowledgeable in conventional educational pedagogy, but also the subjects of NGSS and NOS. Additional training and support centered around NGSS is recommended for science educators interested in integrating NOS into their curriculum and instruction.

A study of school mathematics curriculum enacted by competent teachers in Singapore secondary schools is a programmatic research project at the National Institute of Education (NIE) funded by the Ministry of Education (MOE) in Singapore through the Office of Education Research (OER) at NIE. The main goal of the project is to collect a set of data that would be used by two studies to research the enacted secondary school mathematics curriculum. The project aims to examine how competent experienced secondary school teachers implement the designated curriculum prescribed by the MOE in the 2013 revision of curriculum. It does this firstly by examining the video recordings of the classroom instruction and interactions between secondary school mathematics teachers and their students, as it is these interactions that fundamentally determine the nature of the actual mathematics learning and teaching that take place in the classroom. It also examines content through the instructional materials used—their preparation, use in classroom and as homework. The project comprises a video segment and a survey segment. Approximately 630 secondary mathematics teachers and 600 students are participating in the project. The data collection for the video segment of the project is guided by the renowned complementary accounts methodology while the survey segment adopts a self-report questionnaire approach. The findings of the project will serve several purposes. They will provide timely feedback to mathematics specialists in the MOE, inform pre-service and professional development programmes for mathematics teachers at the NIE and contribute towards articulation of "Mathematics pedagogy in Singapore secondary schools" that is evidence based.

JOURNAL CLUB: Redefining the Radiology Curriculum in Medical School: Vertical Integration and Global Accessibility.

Science.gov (United States)

Retrouvey, Michele; Trace, Anthony Paul; Goodmurphy, Craig W; Shaves, Sarah

2018-01-01

Radiology interconnects medical disciplines given that a working understanding of imaging is essential to clinicians of every specialty. Using online education, we created a globally accessible, web-based undergraduate medical radiology curriculum modeled after the National Medical Student Curriculum in Radiology program of the Alliance of Medical Student Educators in Radiology. Seventy-four radiology faculty-mentored video modules were produced, 50 of which were integrated into the 1st-year anatomy course. We administered tests to medical students before and after students saw the videos to assess the effectiveness of the modules. We surveyed students on their interests in pursuing radiology as a career before and after participating in this curriculum. On the preexamination questions, the mean score was 58.0%, which increased to 83.6% on the pair-matched imaging-related questions on the actual examination. Before participating in the new curriculum, 88% of students did not express an interest in radiology, and 9% were undecided about radiology as a future career. There was an increase in students who reported that they would definitely or most likely pursue a career in radiology (7%) after they had viewed the lectures. Radiology education is now available to a greater number of multidisciplinary learners worldwide. This project produced a comprehensive, globally accessible radiology curriculum in a self-paced, flexible learning format for new generations of physicians.

Mentoring and Argumentation in a Game-Infused Science Curriculum

Science.gov (United States)

Gould, Deena L.; Parekh, Priyanka

2018-04-01

Engaging in argumentation from evidence is challenging for most middle school students. We report the design of a media-based mentoring system to support middle school students in engaging in argumentation in the context of a game-infused science curriculum. Our design emphasizes learners apprenticing with college student mentors around the socio-scientific inquiry of a designed video game. We report the results of a mixed-methods study examining the use of this media-based mentoring system with students ages 11 through 14. We observed that the discourse of groups of students that engaged with the game-infused science curriculum while interacting with college student mentors via a social media platform demonstrated statistically significant higher ratings of cognitive, epistemic, and social aspects of argumentation than groups of students that engaged with the social media platform and game-infused science curriculum without mentors. We further explored the differences between the Discourses of the mentored and non-mentored groups. This analysis showed that students in the mentored groups were invited, guided, and socialized into roles of greater agency than students in the non-mentored groups. This increased agency might explain why mentored groups demonstrated higher levels of scientific argumentation than non-mentored groups. Based on our analyses, we argue that media-based mentoring may be designed around a video game to support middle school students in engaging in argumentation from evidence.

2016-12-01

Paramedic trainees in developing countries face complex and chaotic clinical environments that demand effective leadership, communication, and teamwork. Providers must rely on non-technical skills (NTS) to manage bystanders and attendees, collaborate with other emergency professionals, and safely and appropriately treat patients. The authors designed a NTS curriculum for paramedic trainees focused on adaptive leadership, teamwork, and communication skills critical to the Indian prehospital environment. Forty paramedic trainees in the first academic year of the 2-year Advanced Post-Graduate Degree in Emergency Care (EMT-paramedic equivalent) program at the GVK-Emergency Management and Research Institute campus in Hyderabad, India, participated in the 6-day leadership course. Trainees completed self-assessments and delivered two brief video-recorded presentations before and after completion of the curriculum. Independent blinded observers scored the pre- and post-intervention presentations delivered by 10 randomly selected paramedic trainees. The third-party judges reported significant improvement in both confidence (25 %, p leadership (2.6 vs. 4.6, p confidence (3.0 vs. 4.8, p leadership curriculum for prehospital providers demonstrated significant improvement in self-reported NTS commonly required of paramedics in the field. The authors recommend integrating focused NTS development curriculum into Indian paramedic education and further evaluation of the long term impacts of this adaptive leadership training.

George Nauck of ENCORE!!! invented and markets the Advanced Range Performance (ARPM) Video Golf System for measuring the result of a golf swing. After Nauck requested their assistance, Marshall Space Flight Center scientists suggested video and image processing/computing technology, and provided leads on commercial companies that dealt with the pertinent technologies. Nauck contracted with Applied Research Inc. to develop a prototype. The system employs an elevated camera, which sits behind the tee and follows the flight of the ball down range, catching the point of impact and subsequent roll. Instant replay of the video on a PC monitor at the tee allows measurement of the carry and roll. The unit measures distance and deviation from the target line, as well as distance from the target when one is selected. The information serves as an immediate basis for making adjustments or as a record of skill level progress for golfers.

Modular integrated video system (MIVS) review station

International Nuclear Information System (INIS)

Garcia, M.L.

1988-01-01

An unattended video surveillance unit, the Modular Integrated Video System (MIVS), has been developed by Sandia National Laboratories for International Safeguards use. An important support element of this system is a semi-automatic Review Station. Four component modules, including an 8 mm video tape recorder, a 4-inch video monitor, a power supply and control electronics utilizing a liquid crystal display (LCD) are mounted in a suitcase for probability. The unit communicates through the interactive, menu-driven LCD and may be operated on facility power through the world. During surveillance, the MIVS records video information at specified time intervals, while also inserting consecutive scene numbers and tamper event information. Using either of two available modes of operation, the Review Station reads the inserted information and counts the number of missed scenes and/or tamper events encountered on the tapes, and reports this to the user on the LCD. At the end of a review session, the system will summarize the results of the review, stop the recorder, and advise the user of the completion of the review. In addition, the Review Station will check for any video loss on the tape

2014-12-01

The clinical application of robotic surgery is increasing. The skills necessary to perform robotic surgery are unique from those required in open and laparoscopic surgery. A validated laparoscopic surgical skills curriculum (Fundamentals of Laparoscopic Surgery or FLS™) has transformed the way surgeons acquire laparoscopic skills. There is a need for a similar skills training and assessment tool for robotic surgery. Our research group previously developed and validated a robotic training curriculum in a virtual reality (VR) simulator. We hypothesized that novice robotic surgeons could achieve proficiency levels defined by more experienced robotic surgeons on the VR robotic curriculum, and that this would result in improved performance on the actual daVinci Surgical System™. 25 medical students with no prior robotic surgery experience were recruited. Prior to VR training, subjects performed 2 FLS tasks 3 times each (Peg Transfer, Intracorporeal Knot Tying) using the daVinci Surgical System™ docked to a video trainer box. Task performance for the FLS tasks was scored objectively. Subjects then practiced on the VR simulator (daVinci Skills Simulator) until proficiency levels on all 5 tasks were achieved before completing a post-training assessment of the 2 FLS tasks on the daVinci Surgical System™ in the video trainer box. All subjects to complete the study (1 dropped out) reached proficiency levels on all VR tasks in an average of 71 (± 21.7) attempts, accumulating 164.3 (± 55.7) minutes of console training time. There was a significant improvement in performance on the robotic FLS tasks following completion of the VR training curriculum. Novice robotic surgeons are able to attain proficiency levels on a VR simulator. This leads to improved performance in the daVinci surgical platform on simulated tasks. Training to proficiency on a VR robotic surgery simulator is an efficient and viable method for acquiring robotic surgical skills.

Video: useful tool for delivering family planning messages.

Science.gov (United States)

Sumarsono, S K

1985-10-01

In 1969, the Government of Indonesia declared that the population explosion was a national problem. The National Family Planning Program was consequently launched to encourage adoption of the ideal of a small, happy and prosperous family norm. Micro-approach messages are composed of the following: physiology of menstruation; reproductive process; healthy pregnancy; rational family planning; rational application of contraceptives; infant and child care; nutrition improvement; increase in breastfeeding; increase in family income; education in family life; family health; and deferred marriage age. Macro-approach messages include: the population problem and its impact on socioeconomic aspects; efforts to cope with the population problem; and improvement of women's lot. In utilizing the media and communication channels, the program encourages the implementation of units and working units of IEC to produce IEC materials; utilizes all possible existing media and IEC channels; maintains the consistent linkage between the activity of mass media and the IEC activities in the field; and encourages the private sector to participate in the production of IEC media and materials. A media production center was set up and carries out the following activities: producing video cassettes for tv broadcasts of family planning drama, family planning news, and tv spots; producing duplicates of the video cassettes for distribution to provinces in support of the video network; producing teaching materials for family planning workers; and transfering family planning films into video cassettes. A video network was developed and includes video monitors in family planning service points such as hospitals, family planning clinics and public places like bus stations. In 1985, the program will be expanded by 50 mobile information units equipped with video monitors. Video has potentials to increase the productivity and effectiveness of the family planning program. The video production process is

The closed circuit television (CCTV) system that is onboard the Space Shuttle has the following capabilities: camera, video signal switching and routing unit (VSU); and Space Shuttle video tape recorder. However, this system is inadequate for use with many experiments that require video imaging. In order to assess the state-of-the-art in video technology and data storage systems, a survey was conducted of the High Resolution, High Frame Rate Video Technology (HHVT) products. The performance of the state-of-the-art solid state cameras and image sensors, video recording systems, data transmission devices, and data storage systems versus users' requirements are shown graphically.

Nightingale, James; Wang, Qi; Grecos, Christos; Goma, Sergio R.

2014-05-01

As network service providers seek to improve customer satisfaction and retention levels, they are increasingly moving from traditional quality of service (QoS) driven delivery models to customer-centred quality of experience (QoE) delivery models. QoS models only consider metrics derived from the network however, QoE models also consider metrics derived from within the video sequence itself. Various spatial and temporal characteristics of a video sequence have been proposed, both individually and in combination, to derive methods of classifying video content either on a continuous scale or as a set of discrete classes. QoE models can be divided into three broad categories, full reference, reduced reference and no-reference models. Due to the need to have the original video available at the client for comparison, full reference metrics are of limited practical value in adaptive real-time video applications. Reduced reference metrics often require metadata to be transmitted with the bitstream, while no-reference metrics typically operate in the decompressed domain at the client side and require significant processing to extract spatial and temporal features. This paper proposes a heuristic, no-reference approach to video content classification which is specific to HEVC encoded bitstreams. The HEVC encoder already makes use of spatial characteristics to determine partitioning of coding units and temporal characteristics to determine the splitting of prediction units. We derive a function which approximates the spatio-temporal characteristics of the video sequence by using the weighted averages of the depth at which the coding unit quadtree is split and the prediction mode decision made by the encoder to estimate spatial and temporal characteristics respectively. Since the video content type of a sequence is determined by using high level information parsed from the video stream, spatio-temporal characteristics are identified without the need for full decoding and can

Temporal Segmentation of MPEG Video Streams

Directory of Open Access Journals (Sweden)

Janko Calic

2002-06-01

Full Text Available Many algorithms for temporal video partitioning rely on the analysis of uncompressed video features. Since the information relevant to the partitioning process can be extracted directly from the MPEG compressed stream, higher efficiency can be achieved utilizing information from the MPEG compressed domain. This paper introduces a real-time algorithm for scene change detection that analyses the statistics of the macroblock features extracted directly from the MPEG stream. A method for extraction of the continuous frame difference that transforms the 3D video stream into a 1D curve is presented. This transform is then further employed to extract temporal units within the analysed video sequence. Results of computer simulations are reported.

The energy and greenhouse-gas implications of internet video streaming in the United States

Shehabi, Arman; Walker, Ben; Masanet, Eric

2014-01-01

The rapid growth of streaming video entertainment has recently received attention as a possibly less energy intensive alternative to the manufacturing and transportation of digital video discs (DVDs). This study utilizes a life-cycle assessment approach to estimate the primary energy use and greenhouse-gas emissions associated with video viewing through both traditional DVD methods and online video streaming. Base-case estimates for 2011 video viewing energy and CO 2 (e) emission intensities indicate video streaming can be more efficient than DVDs, depending on DVD viewing method. Video streaming benefits from relatively more efficient end-user devices than DVD viewing, though much of that savings is lost when accounting for the additional energy from network data transmission. Video streaming appears distinctly favorable when compared against any DVD viewing that includes consumer driving, which significantly increases the energy and CO 2 (e) emissions per viewing hour. Total US 2011 video viewing required about 192 PJ of primary energy and emitted about 10.5 billion kg of CO 2 (e). Shifting all 2011 DVD viewing to video streaming reduces the total primary energy use to about 162 PJ and the CO 2 (e) emissions to about 8.6 billion kg, representing a savings equivalent to the primary energy used to meet the electricity demand of nearly 200 000 US households each year. Sensitivity analysis indicates that results are most influenced by the end-user DVD player power demand, data transmission energy, and consumer travel for store DVDs. Data center energy use—both operational and embodied within the IT equipment—account for <1% of the total video streaming energy use. Results from this study indicate that designers and policy makers should focus on the efficiency of end-user devices and network transmission energy to curb future increases in energy use from the proliferation of video streaming.

Fox, R. J.; Connaughton, M.

2017-12-01

Understanding an ecosystem and how humans impact it requires a multidisciplinary perspective and immersive, experiential learning is an exceptional way to achieve understanding. In summer 2017 we took 18 students to the Bermuda Institute of Ocean Sciences (BIOS) as part of a Washington College two-week, four-credit summer field course. We took a multi-disciplinary approach in choosing the curriculum. We focused on the ecology of the islands and surrounding coral reefs as well as the environmental impacts humans are having on the islands. Additionally, we included geology and both local and natural history. Our teaching was supplemented by the BIOS staff and local tour guides. The student learning was integrated and reinforced through student-led video projects. Groups of three students were tasked with creating a 5-7 minute video appropriate for a public audience. We selected video topics based upon locations we would visit in the first week and topics were randomly assigned. The project intention was for the students to critically analyze and evaluate an area of Bermuda that is a worthwhile tourist destination. Students presented why a tourist should visit a locale, the area's ecological distinctiveness and complexity, the impact humans are having, and ways tourists can foster stewardship of that locale. These projects required students to learn how to make and edit videos, collaborate with peers, communicate a narrative to the public, integrate multi-disciplinary topics for a clear, whole-system perspective, observe the environment from a critical viewpoint, and interview local experts. The students produced the videos within the two-week period, and we viewed the videos as a group on the last day. The students worked hard, were proud of their final products, and produced excellent videos. They enjoyed the process, which provided them opportunities to collaborate, show individual strengths, be creative, and work independently of the instructors.

2012-12-01

Effective communication between intensive care unit (ICU) providers and families is crucial given the complexity of decisions made regarding goals of therapy. Using video images to supplement medical discussions is an innovative process to standardize and improve communication. In this six-month, quasi-experimental, pre-post intervention study we investigated the impact of a cardiopulmonary resuscitation (CPR) video decision support tool upon knowledge about CPR among surrogate decision makers for critically ill adults. We interviewed surrogate decision makers for patients aged 50 and over, using a structured questionnaire that included a four-question CPR knowledge assessment similar to those used in previous studies. Surrogates in the post-intervention arm viewed a three-minute video decision support tool about CPR before completing the knowledge assessment and completed questions about perceived value of the video. We recruited 23 surrogates during the first three months (pre-intervention arm) and 27 surrogates during the latter three months of the study (post-intervention arm). Surrogates viewing the video had more knowledge about CPR (p=0.008); average scores were 2.0 (SD 1.1) and 2.9 (SD 1.2) (out of a total of 4) in pre-intervention and post-intervention arms. Surrogates who viewed the video were comfortable with its content (81% very) and 81% would recommend the video. CPR preferences for patients at the time of ICU discharge/death were distributed as follows: pre-intervention: full code 78%, DNR 22%; post-intervention: full code 59%, DNR 41% (p=0.23).

2015-01-01

Behavioral science and behavioral medicine have not been systematically taught to Japanese undergraduate medical students. A working group under the auspices of Japanese Society of Behavioral Medicine developed an outcome-oriented curriculum of behavioral science/behavioral medicine through three processes: identifying the curriculum contents, holding a joint symposium with related societies, and defining outcomes and proposing a learning module. The behavioral science/behavioral medicine core curriculum consists of 11 units of lectures and four units of practical study. The working group plans to improve the current core curriculum by devising formative assessment methods so that students can learn and acquire attitude as well as the skills and knowledge necessary for student-centered clinical practice.

Various information systems for medical curriculum mapping and harmonization have been developed and successfully applied to date. However, the methods for exploiting the datasets captured inside the systems are rather lacking. We reviewed the existing medical terminologies, nomenclatures, coding and classification systems in order to select the most suitable one and apply it in delivering visual analytic tools and reports for the benefit of medical curriculum designers and innovators. A formal description of a particular curriculum of general medicine is based on 1347 learning units covering 7075 learning outcomes. Two data-analytical reports have been developed and discussed, showing how the curriculum is consistent with the MeSH thesaurus and how the MeSH thesaurus can be used to demonstrate interconnectivity of the curriculum through association analysis. Although the MeSH thesaurus is designed mainly to index medical literature and support searching through bibliographic databases, we have proved its use in medical curriculum mapping as being beneficial for curriculum designers and innovators. The presented approach can be followed wherever needed to identify all the mandatory components used for transparent and comprehensive overview of medical curriculum data.

Engineering the curriculum: Towards an adaptive curriculum

Science.gov (United States)

Johns-Boast, Lynette Frances

The curriculum is one of the most important artefacts produced by higher education institutions, yet it is one of the least studied. Additionally, little is known about the decision-making of academics when designing and developing their curricula, nor how they make use of them. This research investigates how 22 Australian higher education engineering, software engineering, computer science, and information systems academics conceive of curriculum, what approaches they take when designing, and developing course and program curricula, and what use they make of the curriculum. It also considers the implications of these conceptions and behaviour upon their curricula. Data were collected through a series of one-to-one, in-depth, qualitative interviews as well as small focus group sessions and were analysed following Charmaz’ (2006) approach to grounded theory. In this thesis, I argue that the development of curricula for new higher degree programs and courses and / or the updating and innovating of an existing curriculum is a design problem. I also argue that curriculum is a complex adaptive system. Surrounding the design and development of a curriculum is a process of design that leads to the creation of a designed object - the official-curriculum. The official-curriculum provides the guiding principles for its implementation, which involves the design and development of the curriculum-in-use, its delivery, and evaluation. Data show that while the participants conceive of curriculum as a problem of design involving a design process leading to the development of the official-curriculum, surprisingly, their behaviour does not match their conceptions. Over a very short period, their behaviour leads to a process I have called curriculum drift where the official-curriculum and the curriculum-in-use drift away from each other causing the curriculum to lose its integrity. Curricular integrity is characterised through the attributes of alignment, coherence, and

In this paper we describe the practical realization and the analysis of a thought experiment devised by Christiaan Huygens, which was pivotal in his derivation of the formula for the radius of gyration of a compound pendulum. Measurements are realized by recording the experiment with a digital camera, and using a video analysis and modelling software tool to process and extract information from the acquired videos. Using this setup, detailed quantitative comparisons between measurements and theoretical predictions can be carried out, focusing on many relevant topics in the undergraduate physics curriculum, such as the ‘radius of gyration’, conservation of energy, moment of inertia, constraint and reaction forces, and the behaviour of the centre of mass.

Capture and playback synchronization in video conferencing

Science.gov (United States)

Shae, Zon-Yin; Chang, Pao-Chi; Chen, Mon-Song

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.

The authors have been developing a measurement system for bubbly flow in order to clarify its multi-dimensional flow characteristics and to offer a data base to validate numerical codes for multi-dimensional two-phase flow. In this paper, the measurement system combining an ultrasonic velocity profile monitor with a video data processing unit is proposed, which can measure simultaneously velocity profiles in both gas and liquid phases, a void fraction profile for bubbly flow in a channel, and an average bubble diameter and void fraction. Furthermore, the proposed measurement system is applied to measure flow characteristics of a bubbly countercurrent flow in a vertical rectangular channel to verify its capability. (author)

No universal solution, based on an approved pedagogical approach, exists to parametrically describe, effectively manage, and clearly visualize a higher education institution's curriculum, including tools for unveiling relationships inside curricular datasets. We aim to solve the issue of medical curriculum mapping to improve understanding of the complex structure and content of medical education programs. Our effort is based on the long-term development and implementation of an original web-based platform, which supports an outcomes-based approach to medical and healthcare education and is suitable for repeated updates and adoption to curriculum innovations. We adopted data exploration and visualization approaches in the context of medical curriculum innovations in higher education institutions domain. We have developed a robust platform, covering detailed formal metadata specifications down to the level of learning units, interconnections, and learning outcomes, in accordance with Bloom's taxonomy and direct links to a particular biomedical nomenclature. Furthermore, we used selected modeling techniques and data mining methods to generate academic analytics reports from medical curriculum mapping datasets. We present a solution that allows users to effectively optimize a curriculum structure that is described with appropriate metadata, such as course attributes, learning units and outcomes, a standardized vocabulary nomenclature, and a tree structure of essential terms. We present a case study implementation that includes effective support for curriculum reengineering efforts of academics through a comprehensive overview of the General Medicine study program. Moreover, we introduce deep content analysis of a dataset that was captured with the use of the curriculum mapping platform; this may assist in detecting any potentially problematic areas, and hence it may help to construct a comprehensive overview for the subsequent global in-depth medical curriculum

Kwah, Helen; Milne, Catherine; Tsai, Tzuchi; Goldman, Ricki; Plass, Jan L.

2016-09-01

This formative design study examines how a program curriculum and implementation was emergently (re)designed in dynamic relation to the expressed emotions of teachers and students. The context was a yearlong afterschool game design program for STEM learning at an urban and public all-girls middle school. Using Randall Collins' (Interaction ritual chains, Princeton University Press, Princeton, 2004) sociology of emotions framework, our analysis of field notes and video data reveal how the original intended curriculum hindered the generation of positive emotions, mutual foci of attention, and feelings of group solidarity—factors important in the generation of successful group interactions. In response to teacher and student expressed emotions, we took these factors as a guide for redesigning the program curriculum and implementation in order to foster a more positive emotional climate and redirect students' positive emotions toward engagement in learning goals. This study's implications point to the possibilities for designing curricula and program implementations to engender more emotionally responsive environments for STEM learning.

Biology Reflective Assessment Curriculum

Science.gov (United States)

Bayley, Cheryl Ann

Often students and educators view assessments as an obligation and finality for a unit. In the current climate of high-stakes testing and accountability, the balance of time, resources and emphasis on students' scores related to assessment have been slanted considerably toward the summative side. This tension between assessment for accountability and assessment to inform teaching strains instruction and educators' ability to use that information to design learning opportunities that help students develop deeper conceptual understanding. A substantive body of research indicates that formative and reflective assessment can significantly improve student learning. Biology Reflective Assessment Curriculum (BRAC) examines support provided for high school science students through assessment practices. This investigation incorporates the usage of reflective assessments as a guiding practice for differentiated instruction and student choice. Reflective assessment is a metacognitive strategy that promotes self-monitoring and evaluation. The goals of the curriculum are to promote self-efficacy and conceptual understanding in students learning biology through developing their metacognitive awareness. BRAC was implemented in a high school biology classroom. Data from assessments, metacognitive surveys, self-efficacy surveys, reflective journals, student work, a culminating task and field notes were used to evaluate the effectiveness of the curriculum. The results suggest that students who develop their metacognitive skills developed a deeper conceptual understanding and improved feelings of self-efficacy when they were engaged in a reflective assessment unit embedded with student choice. BRAC is a tool for teachers to use assessments to assist students in becoming metacognitive and to guide student choice in learning opportunities.

Novel memory architecture for video signal processor

Science.gov (United States)

Hung, Jen-Sheng; Lin, Chia-Hsing; Jen, Chein-Wei

1993-11-01

An on-chip memory architecture for video signal processor (VSP) is proposed. This memory structure is a two-level design for the different data locality in video applications. The upper level--Memory A provides enough storage capacity to reduce the impact on the limitation of chip I/O bandwidth, and the lower level--Memory B provides enough data parallelism and flexibility to meet the requirements of multiple reconfigurable pipeline function units in a single VSP chip. The needed memory size is decided by the memory usage analysis for video algorithms and the number of function units. Both levels of memory adopted a dual-port memory scheme to sustain the simultaneous read and write operations. Especially, Memory B uses multiple one-read-one-write memory banks to emulate the real multiport memory. Therefore, one can change the configuration of Memory B to several sets of memories with variable read/write ports by adjusting the bus switches. Then the numbers of read ports and write ports in proposed memory can meet requirement of data flow patterns in different video coding algorithms. We have finished the design of a prototype memory design using 1.2- micrometers SPDM SRAM technology and will fabricated it through TSMC, in Taiwan.

Excessive video game use among youth has been a growing concern in the United States and elsewhere. The aims of this study are to establish validity of a video game measure in a large adolescent inpatient sample, identify clinical factors underlying problem video game use, and identify associations with measures of psychopathology. Three hundred eighty participants admitted to an adolescent inpatient psychiatric unit between November 2007 and March 2009 were administered a battery of self-report measures, including a questionnaire developed for this study that assessed reinforcers and consequences of past-year video game use (ie, Problematic Video Game Use Scale). Factor analysis was used to identify the underlying structure of behaviors associated with problem video game use. A factor analysis of the Problematic Video Game Use Scale indicated 2 primary factors. One was associated with engaging in problem behaviors that impaired the adolescent's functioning as a result of playing video games and one reflected the reinforcing effects of playing video games. Both factors were associated with measures of psychopathology, although associations were generally stronger for impairment in functioning than for reinforcing effects. Both factors were significantly correlated with self-reported daily video game use (P video game playing: impairment in functioning and reinforcing effects. Initial evidence of the content validity of the video game measure was established. Findings highlight the importance of assessing video game use among an adolescent population, the factors associated with video game use, and associations with symptoms of psychopathology. Limitations include a common reporter for multiple measures and cross-sectional data that do not allow for causal links to be made. © Copyright 2011 Physicians Postgraduate Press, Inc.

Spaceship Earth: A partnership in curriculum writing

Lindstrom, Marilyn M.

1993-01-01

As the Apollo astronauts left Earth to venture onto the surface of another planetary body, they saw their home planet in a new global perspective. Unmanned NASA missions have given us a closer look at all the other planets in our solar system and emphasized the uniqueness of Earth as the only place in our solar system that can sustain life as we know it. Spaceship Earth is a new science curriculum which was developed to help students and teachers to explore the Earth, to see it in the global perspective, and to understand the relationships among life, the planet, and the sun. Astronaut photographs, especially shuttle pictures, are used as groundbased studies to help students to understand global Earth Science and integrate various aspects of physical, life, and social science. The Spaceship Earth curriculum was developed at by a team of JSC scientists working in collaboration with teachers from local school districts. This project was done under the auspices of Partner-In-Space, a local non-profit organization dedicated to improving science education and our general knowledge of space. The team met once a month for a year then assembled the curriculum during the summer. The project is now in the testing stage as the teachers try it out in their classrooms. It was supported by the Texas Education Agency and will be offered by the State of Texas as a supplemental curriculum for statewide use. Because the curriculum was developed by teachers, it is self contained and the lessons are easy to implement and give students concrete experiences. The three sub-units follow in a logical order, but may be used independently. If they are used separately, they may be tied together by the teacher returning to the basic theme of the global Earth as each unit is completed.

As the adoption of robotic procedures becomes more widespread, additional risk related to the learning curve can be expected. This article reports the results of a Delphi process to define procedures to optimize robotic training of thoracic surgeons and to promote safe performance of established robotic interventions as, for example, lung cancer and thymoma surgery. In June 2016, a working panel was spontaneously created by members of the European Society of Thoracic Surgeons (ESTS) and European Association for Cardio-Thoracic Surgery (EACTS) with a specialist interest in robotic thoracic surgery and/or surgical training. An e-consensus-finding exercise using the Delphi methodology was applied requiring 80% agreement to reach consensus on each question. Repeated iterations of anonymous voting continued over 3 rounds. Agreement was reached on many points: a standardized robotic training curriculum for robotic thoracic surgery should be divided into clearly defined sections as a staged learning pathway; the basic robotic curriculum should include a baseline evaluation, an e-learning module, a simulation-based training (including virtual reality simulation, Dry lab and Wet lab) and a robotic theatre (bedside) observation. Advanced robotic training should include e-learning on index procedures (right upper lobe) with video demonstration, access to video library of robotic procedures, simulation training, modular console training to index procedure, transition to full-procedure training with a proctor and final evaluation of the submitted video to certified independent examiners. Agreement was reached on a large number of questions to optimize and standardize training and education of thoracic surgeons in robotic activity. The production of the content of the learning material is ongoing.

Volunteer educators bring their own ideas about effective teaching to a 4-H curriculum

Full Text Available Youth programs implemented during out-of-school time often rely on volunteers. These volunteers are responsible for selecting and adapting curriculum and facilitating activities, so their pedagogical practices become primary contributors to program quality, and ultimately, youth outcomes. To describe volunteers' pedagogical practices, I conducted a qualitative case study at three sites where volunteer educators were implementing a design-based 4-H curriculum. The curriculum advanced youth scientific literacy by supporting scientific inquiry in conjunction with planning, designing and making shareable artifacts. Through detailed observations, videos and focus groups, I identified six common pedagogical practices, though educators differed widely in which ones they used. Pragmatic and structural constraints shaped their choices, as did their professional identification as engineers, or not, and their relative comfort with engineering. To support volunteer educators in implementing a learner-centered educational program, curricula designers might be more specific in recommending and explaining pedagogical practices, and program managers might better train volunteer educators in those preferred practices.

Novel Intermode Prediction Algorithm for High Efficiency Video Coding Encoder

2014-01-01

Full Text Available The joint collaborative team on video coding (JCT-VC is developing the next-generation video coding standard which is called high efficiency video coding (HEVC. In the HEVC, there are three units in block structure: coding unit (CU, prediction unit (PU, and transform unit (TU. The CU is the basic unit of region splitting like macroblock (MB. Each CU performs recursive splitting into four blocks with equal size, starting from the tree block. In this paper, we propose a fast CU depth decision algorithm for HEVC technology to reduce its computational complexity. In 2N×2N PU, the proposed method compares the rate-distortion (RD cost and determines the depth using the compared information. Moreover, in order to speed up the encoding time, the efficient merge SKIP detection method is developed additionally based on the contextual mode information of neighboring CUs. Experimental result shows that the proposed algorithm achieves the average time-saving factor of 44.84% in the random access (RA at Main profile configuration with the HEVC test model (HM 10.0 reference software. Compared to HM 10.0 encoder, a small BD-bitrate loss of 0.17% is also observed without significant loss of image quality.

The Aesthetics of the Ambient Video Experience

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.

Full Text Available Modern curriculum theories emphasize that if we understand the curriculum as a real core substance of education. We have to bear in mind, when planning the curriculum, the whole multitude of factors (curricula which have an influence on the educational impact. In the field of andragogy, we especially have to consider educational needs, and linking the strategies of instruction with those of learning. The best way of realizing this principle is the open strategy of planning the national curriculum and process-developmental strategy of planning with the microandragogic situation. This planning strategy is S1m1lar to the system-integration strategy and Jarvis's model of negotiated curriculum, which derive from the basic andragogic principle: that the interests and capacities of adults for education increase if we enable them to cooperate in the planning and production of the curriculum.

Hendricson, W D; Payer, A F; Rogers, L P; Markus, J F

1993-03-01

Numerous study commissions have contended that departmental territoriality and lack of coordinated planning are stagnating contemporary medical education. As a cure, these commissions have recommended the creation of centralized academic management units empowered to oversee revitalization of the curriculum through a series of reforms, including better definition of graduation competencies, community-based training, interdisciplinary courses, problem-based learning, and modernization of evaluation strategies. To determine the extent to which these recommendations were being adopted, in 1990 the authors sent a questionnaire on curriculum committee functions, current innovation efforts, and future priorities to academic administrators and members of medical school curriculum committees at 143 North American medical schools. Responses were received from administrators (primarily associate deans for academic affairs) at 118 schools and committee members (primarily faculty) at 111 schools. Recommendations for enhancing curriculum committee effectiveness were also elicited. The authors conclude that centralization of curricular management has occurred at very few institutions, and that the commonly mentioned reforms are being adopted at a modest pace. The results are analyzed in light of theories of the institutional change process and strategies for introducing educational innovations into established institutions.

The Influence of Curriculum, Instruction, Technology, and Social Interactions on Two Fifth-Grade Students' Epistemologies in Modeling Throughout a Model-Based Curriculum Unit

Science.gov (United States)

Baek, Hamin; Schwarz, Christina V.

2015-04-01

In the past decade, reform efforts in science education have increasingly attended to engaging students in scientific practices such as scientific modeling. Engaging students in scientific modeling can help them develop their epistemologies by allowing them to attend to the roles of mechanism and empirical evidence when constructing and revising models. In this article, we present our in-depth case study of how two fifth graders—Brian and Joon—who were students in a public school classroom located in a Midwestern state shifted their epistemologies in modeling as they participated in the enactment of a technologically enhanced, model-based curriculum unit on evaporation and condensation. First, analyses of Brian's and Joon's models indicate that their epistemologies in modeling related to explanation and empirical evidence shifted productively throughout the unit. Additionally, while their initial and final epistemologies in modeling were similar, the pathways in which their epistemologies in modeling shifted differed. Next, analyses of the classroom activities illustrate how various components of the learning ecology including technological tools, the teacher's scaffolding remarks, and students' collective activities and conversations, were marshaled in the service of the two students' shifting epistemologies in modeling. These findings suggest a nuanced view of individual learners' engagement in scientific modeling, their epistemological shifts in the practice, and the roles of technology and other components of a modeling-oriented learning environment for such shifts.

The quality of problem representation is critical for developing students' problem-solving abilities in problem-based learning (PBL). This study investigates preclinical students' experience with standardized patients (SPs) as a problem representation method compared to using video cases in PBL. A cohort of 99 second-year preclinical students from Inje University College of Medicine (IUCM) responded to a Likert scale questionnaire on their learning experiences after they had experienced both video cases and SPs in PBL. The questionnaire consisted of 14 items with eight subcategories: problem identification, hypothesis generation, motivation, collaborative learning, reflective thinking, authenticity, patient-doctor communication, and attitude toward patients. The results reveal that using SPs led to the preclinical students having significantly positive experiences in boosting patient-doctor communication skills; the perceived authenticity of their clinical situations; development of proper attitudes toward patients; and motivation, reflective thinking, and collaborative learning when compared to using video cases. The SPs also provided more challenges than the video cases during problem identification and hypotheses generation. SPs are more effective than video cases in delivering higher levels of authenticity in clinical problems for PBL. The interaction with SPs engages preclinical students in deeper thinking and discussion; growth of communication skills; development of proper attitudes toward patients; and motivation. Considering the higher cost of SPs compared with video cases, SPs could be used most advantageously during the preclinical period in the IUCM curriculum.

This study examines the development and implementation of a pilot human factors curriculum during a 2-year period. It is one component of a comprehensive 5-year human factors curriculum spanning core competencies of interpersonal and communication skills, systems-based practice, and professionalism and using low-and high-fidelity simulation techniques. Members of the Department of Surgery and the Center for Clinical Communication and Performance Outcomes jointly constructed a curriculum for PGY1 and PGY2 residents on topics ranging from challenging communication to time and stress management. Video demonstrations, triggers, and simulated scenarios involving acting patients were created by surgeons and medical educators. Pre- and postintervention measures were obtained for communication skills, perceived stress level, and teamwork. Communication skills were evaluated using a series of video vignettes. The validated Perceived Stress Scale and Teamwork and Patient Safety Attitudes survey were used. Residents' perceptions of the program were also measured. Twenty-seven PGY1 residents and 15 PGY2 residents participated during 2 years. Analyses of video vignette tests indicated significant improvement in empathic communication for PGY1 (t = 3.62, p = 0.001) and PGY2 (t = 5.00, p = 0.004). There were no significant changes to teamwork attitudes. Perceived levels of stress became considerably higher. PGY1 residents reported trying 1 to 3 strategies taught in the time management session, with 60% to 75% reporting improvement post-training. This unique and comprehensive human factors curriculum is shown to be effective in building communication competency for junior-level residents in the human and emotional aspects of surgical training and practice. Continued refinement and ongoing data acquisition and analyses are underway. Copyright 2010 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

In recent years, the HIV care provider workforce has not kept pace with an expanding HIV epidemic. To effectively address this HIV workforce shortage, a multipronged approach is needed that includes high-quality, easily accessible, up-to-date HIV education for trainees and practicing providers. Toward this objective, the University of Washington, in collaboration with the AIDS Education and Training Center National Coordinating Resource Center, is developing a modular, dynamic curriculum that addresses the entire spectrum of the HIV care continuum. Herein, we outline the general principles, content, organization, and features of this federally funded National HIV Curriculum, which allows for longitudinal, active, self-directed learning, as well as real-time evaluation, tracking, and feedback at the individual and group level. The online curriculum, which is in development, will provide a free, comprehensive, interactive HIV training and resource tool that can support national efforts to expand and strengthen the United States HIV clinical care workforce.

Priority-based methods for reducing the impact of packet loss on HEVC encoded video streams

Science.gov (United States)

Nightingale, James; Wang, Qi; Grecos, Christos

2013-02-01

The rapid growth in the use of video streaming over IP networks has outstripped the rate at which new network infrastructure has been deployed. These bandwidth-hungry applications now comprise a significant part of all Internet traffic and present major challenges for network service providers. The situation is more acute in mobile networks where the available bandwidth is often limited. Work towards the standardisation of High Efficiency Video Coding (HEVC), the next generation video coding scheme, is currently on track for completion in 2013. HEVC offers the prospect of a 50% improvement in compression over the current H.264 Advanced Video Coding standard (H.264/AVC) for the same quality. However, there has been very little published research on HEVC streaming or the challenges of delivering HEVC streams in resource-constrained network environments. In this paper we consider the problem of adapting an HEVC encoded video stream to meet the bandwidth limitation in a mobile networks environment. Video sequences were encoded using the Test Model under Consideration (TMuC HM6) for HEVC. Network abstraction layers (NAL) units were packetized, on a one NAL unit per RTP packet basis, and transmitted over a realistic hybrid wired/wireless testbed configured with dynamically changing network path conditions and multiple independent network paths from the streamer to the client. Two different schemes for the prioritisation of RTP packets, based on the NAL units they contain, have been implemented and empirically compared using a range of video sequences, encoder configurations, bandwidths and network topologies. In the first prioritisation method the importance of an RTP packet was determined by the type of picture and the temporal switching point information carried in the NAL unit header. Packets containing parameter set NAL units and video coding layer (VCL) NAL units of the instantaneous decoder refresh (IDR) and the clean random access (CRA) pictures were given the

Explore-create-share study: An evaluation of teachers as curriculum innovators in engineering education

Science.gov (United States)

Berry, Ayora

The purpose of this study was to investigate the effects of a curriculum design-based (CDB) professional development model on K-12 teachers' capacity to integrate engineering education in the classroom. This teacher professional development approach differs from other training programs where teachers learn how to use a standard curriculum and adopt it in their classrooms. In a CDB professional development model teachers actively design lessons, student resources, and assessments for their classroom instruction. In other science, technology, engineering and mathematics (STEM) disciplines, CDB professional development has been reported to (a) position teachers as architects of change, (b) provide a professional learning vehicle for educators to reflect on instructional practices and develop content knowledge, (c) inspire a sense of ownership in curriculum decision-making among teachers, and (d) use an instructional approach that is coherent with teachers' interests and professional goals. The CDB professional development program in this study used the Explore-Create-Share (ECS) framework as an instructional model to support teacher-led curriculum design and implementation. To evaluate the impact of the CDB professional development and associated ECS instructional model, three research studies were conducted. In each study, the participants completed a six-month CDB professional development program, the PTC STEM Certificate Program, that included sixty-two instructional contact hours. Participants learned about industry and education engineering concepts, tested engineering curricula, collaborated with K-12 educators and industry professionals, and developed project-based engineering curricula using the ECS framework. The first study evaluated the impact of the CDB professional development program on teachers' engineering knowledge, self-efficacy in designing engineering curriculum, and instructional practice in developing project-based engineering units.

Michigan Science Teaching and Assessment Reform (Mi-STAR) is developing an NGSS-aligned middle school curriculum and associated teacher professional learning program in which science is taught and learned as an integrated body of knowledge that can be applied to address societal issues. With the generous support of the Herbert H. and Grace A. Dow Foundation, Mi-STAR has released several pilot-tested units through the Mi-STAR curriculum portal at mi-star.mtu.edu. Each of these units focuses on an ongoing `Unit Challenge' investigation that integrates STEM content across disciplinary boundaries, stimulates interest, and engages students in using scientific practices to address 21st century challenges. Each Mi-STAR unit is connected to a Unifying NGSS Crosscutting Concept (CCC) that allows students to recognize the concepts that are related to the phenomena or problems under investigation. In the 6th grade, students begin with an exploration of the CCC Systems and System Models. Through repeated applications across units, students refine their understanding of what a system is and how to model a complex Earth system. An example 6th grade unit entitled "Water on the Move: The Water Cycle," provides an example of how Mi-STAR approaches the use of Unifying CCCs and Unit Challenges to enhance middle school students' understanding of the interconnections of Earth system processes and human activities. Throughout the unit, students use a series of hands-on explorations and simulations to explore the hydrologic cycle and how human activity can alter Earth systems. Students develop new knowledge through repeated interactions with the Unit Challenge, which requires development of system models and construction of evidence-based arguments related to flooding problems in a local community. Students have the opportunity to make predictions about how proposed land-use management practices (e.g. development of a skate-park, rain garden, soccer field, etc.) can alter the earth

This paper reports on the development of an engineering curriculum for a new industrial engineering programme at a medium-sized private university in the northeast United States. A systems engineering process has been followed to design and develop the new curriculum. Considering the programme curriculum as a system, first the stakeholders have been identified, and some preliminary analysis on their needs and requirements has been conducted. Following that, the phases of conceptual design, preliminary design, and detailed design have been pursued during which different levels of validation, assessment, and evaluation processes have been utilised. In addition, a curriculum assessment and continuous improvement process have been developed to assess the curriculum and the courses frequently. The resulting curriculum is flexible, allowing the pursuit of accelerated graduate programmes, a second major, various minor options, and study-abroad; relevant, tailored to the needs of industry partners in the vicinity; and practical, providing hands-on education, resulting in employment-ready graduates.

The transition from basic skills training in a skills lab to procedure training in the operating theater using the traditional master-apprentice model (MAM) lacks uniformity and efficiency. When the supervising surgeon performs parts of a procedure, training opportunities are lost. To minimize this intervention by the supervisor and maximize the actual operating time for the trainee, we created a new training method called INtraoperative Video-Enhanced Surgical Training (INVEST). Ten surgical residents were trained in laparoscopic cholecystectomy either by the MAM or with INVEST. Each trainee performed six cholecystectomies that were objectively evaluated on an Objective Structured Assessment of Technical Skills (OSATS) global rating scale. Absolute and relative improvements during the training curriculum were compared between the groups. A questionnaire evaluated the trainee's opinion on this new training method. Skill improvement on the OSATS global rating scale was significantly greater for the trainees in the INVEST curriculum compared to the MAM, with mean absolute improvement 32.6 versus 14.0 points and mean relative improvement 59.1 versus 34.6% (P=0.02). INVEST significantly enhances technical and procedural skill development during the early learning curve for laparoscopic cholecystectomy. Trainees were positive about the content and the idea of the curriculum.

Venkatesan, Ragav; Zwart, Christine M.; Frakes, David H.; Li, Baoxin

2015-03-01

With the advent of progressive format display and broadcast technologies, video deinterlacing has become an important video-processing technique. Numerous approaches exist in the literature to accomplish deinterlacing. While most earlier methods were simple linear filtering-based approaches, the emergence of faster computing technologies and even dedicated video-processing hardware in display units has allowed higher quality but also more computationally intense deinterlacing algorithms to become practical. Most modern approaches analyze motion and content in video to select different deinterlacing methods for various spatiotemporal regions. We introduce a family of deinterlacers that employs spectral residue to choose between and weight control grid interpolation based spatial and temporal deinterlacing methods. The proposed approaches perform better than the prior state-of-the-art based on peak signal-to-noise ratio, other visual quality metrics, and simple perception-based subjective evaluations conducted by human viewers. We further study the advantages of using soft and hard decision thresholds on the visual performance.

The process of reform began in 2014 through a series of iterative meetings and discussions. A working group within the Resident and Fellow Training Committee reviewed case log data from 2012 to 2015. These data were used to propose new criteria designed to provide adequate exposure to core content. The working group also proposed using video assessment of an MIS case to provide objective assessment of competency. Case log data were available for 326 fellows with a total of 85,154 cases logged (median 227 per fellow). The working group proposed new criteria starting with minimum case volumes for five defined categories including foregut (20), bariatrics (25), inguinal hernia (10), ventral hernia (10), and solid organ/colon/thoracic (10). Fellows are expected to perform an additional 75 complex MIS cases of any category for a total of 150 required cases overall. The proposal also included a minimum volume of flexible endoscopy (50) and submission of an MIS foregut case for video assessment. The new criteria more clearly defined which surgeon roles count for major credit within individual categories. Fourteen fellowships volunteered to pilot these new criteria for the 2017-2018 academic year. The new SAGES Advanced GI/MIS fellowship has been crafted to better define the core content that should be contained in these fellowships, while still allowing sufficient heterogeneity so that individual learners can tailor their training to specific areas of interest. The criteria also introduce innovative, evidence-based methods for assessing competency. Pending the results of the pilot program, SAGES will consider broad implementation of the new fellowship criteria.

Optical mineralogy is not an easy skill to master as an undergraduate, but it is crucial for understanding what the Earth is made out of. It is a supplementary and specific skillset typically taught in a microscope lab supporting lessons on crystallography, chemistry and mineral analysis in the classroom. Mastering the basic skills is required for advancement in courses that utilize thin sections in teaching igneous, metamorphic, and sedimentary rocks. This project asks: Will exposing undergraduate Earth and environmental studies students to optical microscopy figures in videos prior to lab assist in the acquisition of skills required to describe and distinguish Earth materials? This project is conducted in conjunction with the Blended and Online Learning Design (BOLD) Fellowship offered through the Center for Teaching (CFT) at Vanderbilt University. Eight videos and accompanying pre-lab questions were hosted online weekly in a semester-long, undergraduate Earth materials course. The focus of the design of the videos and supporting questions is specifically on microscopy skills rather than on optics concepts, which is taught post-video. The videos were made available prior to a weekly lab with the intent of familiarizing the student with the types of images and information he/she should obtain with the microscope. Multiple choice, formative-style questions accompany the videos in an online-hosted assignment. These questions are graded on basis of completion and are intended to aid in student metacognition. Subjects include students in the Vanderbilt University Earth Materials course and students from the Hanover College Mineralogy course. The effectiveness of the videos is assessed in two parts: (1) Comparing the homework and lab final grades of the students this year with those of the students last year (2) Analysis of a weekly questionnaire. The answers after each week will be compiled and compared. Collecting data from Vanderbilt University students and Hanover

Multimedia learning has been shown effective in clinical skills training. Yet, use of technology presents both opportunities and challenges to learners. The present study investigated student use and perceptions of online clinical videos for learning clinical skills and in preparing for OSCE (Objective Structured Clinical Examination). This study aims to inform us how to make more effective us of these resources. A mixed-methods study was conducted for this study. A 30-items questionnaire was administered to investigate student use and perceptions of OSCE videos. Year 3 and 4 students from 34 Korean medical schools who had access to OSCE videos participated in the online survey. Additionally, a semi-structured interview of a group of Year 3 medical students was conducted for an in-depth understanding of student experience with OSCE videos. 411 students from 31 medical schools returned the questionnaires; a majority of them found OSCE videos effective for their learning of clinical skills and in preparing for OSCE. The number of OSCE videos that the students viewed was moderately associated with their self-efficacy and preparedness for OSCE (p mobile devices; they agreed more with the statement that it was convenient to access the video clips than their peers who accessed the videos using computers (p students reported lack of integration into the curriculum and lack of interaction as barriers to more effective use of OSCE videos. The present study confirms the overall positive impact of OSCE videos on student learning of clinical skills. Having faculty integrate these learning resources into their teaching, integrating interactive tools into this e-learning environment to foster interactions, and using mobile devices for convenient access are recommended to help students make more effective use of these resources.

Schick, Andreas; Cierpka, Manfred

2009-01-01

Schools and kindergartens are particularly suitable for the implementation of violence prevention programs. Many German schools and kindergartens have securely established the violence prevention curriculum Faustlos. The Faustlos programs for kindergartens and elementary schools are now complemented with the version for middle schools. As the kindergarten- and elementary school versions the middle school program too focuses on the theoretically profound, age group-tailored promotion of empathy, impulse control and anger management. These dimensions are subdivided into the five themes "understanding the problem" "training for empathy"; "anger management", "problem solving" and "applying skills" and taught stepwise, highly structured and based on several video sequences in 31 lessons. US-American evaluation studies proof the effectiveness and the violence prevention potential of the program. With the curriculum for middle schools a comprehensive Faustlos program package is now made available to sustainably promote core violence prevention competences of children and adolescents on a developmentally appropriate level and with a consistent didactic approach.

2017-05-01

Full Text Available Aim/Purpose: The number of students enrolled in online courses that use video lectures is on the rise. However, research shows that the number of students watching video lectures is low, and the number watching videos to completion is even lower. Background: This paper seeks to understand this problem by looking for correlations between instructional design and student engagement with video lectures. Methodology: Students at a cyber-university in South Korea (n=1801 were surveyed on their perception of the instructional design used in the courses they took and their engagement with online video lectures. Contribution: This paper contributes to the body of knowledge by demonstrating positive correlations between instructional design, watching, and finishing video lectures. Findings: While most other research has found low levels of online lecture viewership, this paper found significantly higher numbers watching and finishing videos. Other major findings of the paper are that five key elements of instructional design for online learning environments (designing methods, setting the curriculum, establishing time parameters, establishing netiquette, and utilizing the medium effectively all correlated positively with students watching and finishing video lectures. Recommendations for Practitioners\t: Based on findings in this paper, it is recommended that practitioners consider taking actions when designing their instruction for online courses. These include batching their video lectures together by topic, devoting greater resources to helping students utilize the medium, and communicate time parameters in a way that encourages students to view video lectures in a timely manner. Recommendation for Researchers: As the watching of video lectures in this study was mandatory for learners, an interesting area of further research would be to examine whether that decision led to higher numbers of students watching them. Future Research: It is important for

User and Device Adaptation in Summarizing Sports Videos

Science.gov (United States)

Nitta, Naoko; Babaguchi, Noboru

Video summarization is defined as creating a video summary which includes only important scenes in the original video streams. In order to realize automatic video summarization, the significance of each scene needs to be determined. When targeted especially on broadcast sports videos, a play scene, which corresponds to a play, can be considered as a scene unit. The significance of every play scene can generally be determined based on the importance of the play in the game. Furthermore, the following two issues should be considered: 1) what is important depends on each user's preferences, and 2) the summaries should be tailored for media devices that each user has. Considering the above issues, this paper proposes a unified framework for user and device adaptation in summarizing broadcast sports videos. The proposed framework summarizes sports videos by selecting play scenes based on not only the importance of each play itself but also the users' preferences by using the metadata, which describes the semantic content of videos with keywords, and user profiles, which describe users' preference degrees for the keywords. The selected scenes are then presented in a proper way using various types of media such as video, image, or text according to device profiles which describe the device type. We experimentally verified the effectiveness of user adaptation by examining how the generated summaries are changed by different preference degrees and by comparing our results with/without using user profiles. The validity of device adaptation is also evaluated by conducting questionnaires using PCs and mobile phones as the media devices.

Full Text Available Pedestrians in the vehicle path are in danger of being hit, thus causing severe injury to pedestrians and vehicle occupants. Therefore, real-time pedestrian detection with the video of vehicle-mounted camera is of great significance to vehicle–pedestrian collision warning and traffic safety of self-driving car. In this article, a real-time scheme was proposed based on integral channel features and graphics processing unit. The proposed method does not need to resize the input image. Moreover, the computationally expensive convolution of the detectors and the input image was converted into the dot product of two larger matrixes, which can be computed effectively using a graphics processing unit. The experiments showed that the proposed method could be employed to detect pedestrians in the video of car camera at 20+ frames per second with acceptable error rates. Thus, it can be applied in real-time detection tasks with the videos of car camera.

2018-04-01

The purpose of this study was to assess the usefulness of adding video models of brief alcohol assessment and counseling to a standardized patient (SP) curriculum that covers and tests acquisition of this skill. The authors conducted a single-center, retrospective cohort study of third- and fourth-year medical students between 2013 and 2015. All students completed a standardized patient (SP) encounter illustrating the diagnosis of alcohol use disorder, followed by an SP exam on the same topic. Beginning in August 2014, the authors supplemented the existing formative SP exercise on problem drinking with one of two 5-min videos demonstrating screening, brief intervention, and referral for treatment (SBIRT). P values and Z tests were performed to evaluate differences between students who did and did not see the video in knowledge and skills related to alcohol use disorders. One hundred ninety-four students were included in this analysis. Compared to controls, subjects did not differ in their ability to uncover and accurately characterize an alcohol problem during a standardized encounter (mean exam score 41.29 vs 40.93, subject vs control, p = 0.539). However, the SPs' rating of students' expressions of empathy were significantly higher for the group who saw the video (81.63 vs 69.79%, p videos would improve students' recognition and knowledge of alcohol-related conditions. However, feedback from the SPs produced the serendipitous finding that the communication skills demonstrated in the videos had a sustained effect in enhancing students' professional behavior.

Dimitrova, Nevenka; Abdel-Mottaleb, Mohamed

1997-01-01

This paper presents a novel approach for video retrieval from a large archive of MPEG or Motion JPEG compressed video clips. We introduce a retrieval algorithm that takes a video clip as a query and searches the database for clips with similar contents. Video clips are characterized by a sequence of representative frame signatures, which are constructed from DC coefficients and motion information (`DC+M' signatures). The similarity between two video clips is determined by using their respective signatures. This method facilitates retrieval of clips for the purpose of video editing, broadcast news retrieval, or copyright violation detection.

Full Text Available The complex and multimedia nature of video games results in several original and derivative works of copyright contained in a single game. Although there is no need to establish a new category of work and the current state of law offers comprehensive protection of the works, it also means there can be many different authors in a single production, so assignment of rights can be difficult.This interrelation of works and their respective authors can also have a negative effect on authors' moral rights, or, more specifically, the right to claim authorship and the right to object to derogatory treatment of the work.This article analyses the current law of the United Kingdom with regard to authorship and ownership of copyright in video games and underlying works before analysing and evaluating the moral rights of video games' contributors.

Immersive video

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.

The popularity of synthetic cannabinoids (SCBs) is increasing the chance for adverse health issues in the United States. Moreover, social media platforms such as YouTube that provided a platform for user-generated content can convey misinformation or glorify use of SCBs. The aim of this study was to fill this gap by describing the content of the most popular YouTube videos containing content related to the SCBs. Videos with at least 1000 or more views found under the search terms "K2" and "spice" included in the analysis. The collective number of views was over 7.5 million. Nearly half of videos were consumer produced (n=42). The most common content in the videos was description of K2 (n=69), followed by mentioning dangers of using K2 (n=47), mentioning side effects (n=38) and showing a person using K2 (n=37). One-third of videos (n=34) promoted use of K2, while 22 videos mentioned risk of dying as a consequence of using K2. YouTube could be used as a surveillance tool to combat this epidemic, but instead, the most widely videos related to SCBs are uploaded by consumers. The content of these consumer videos on YouTube often provide the viewer with access to view a wide array of uploaders describing, encouraging, participating and promoting use.

Casady, Victoria

The research conducted for this mixed-method study, qualitative and quantitative, analyzed the results of an academic year-long study to determine whether the use of an integrated fourth grade curriculum would benefit student achievement in the areas of English language arts, social studies, and science more than a subject-based traditional curriculum. The research was conducted based on the international, national, and state test scores, which show a slowing or lack of growth. Through pre- and post-assessments, student questionnaires, and administrative interviews, the researcher analyzed the phenomenological experiences of the students to determine if the integrated curriculum was a beneficial restructuring of the curriculum. The research questions for this study focused on the achievement and attitudes of the students in the study and whether the curriculum they were taught impacted their achievement and attitudes over the course of one school year. The curricula for the study were organized to cover the current standards, where the integrated curriculum focused on connections between subject areas to help students make connections to what they are learning and the world beyond the classroom. The findings of this study indicated that utilizing the integrated curriculum could increase achievement as well as students' attitudes toward specific content areas. The ANOVA analysis for English language arts was not determined to be significant; although, greater growth in the students from the integrated curriculum setting was recorded. The ANOVA for social studies (0.05) and the paired t-tests (0.001) for science both determined significant positive differences. The qualitative analysis led to the discovery that the experiences of the students from the integrated curriculum setting were more positive. The evaluation of the data from this study led the researcher to determine that the integrated curriculum was a worthwhile endeavor to increase achievement and attitudes

Like many technological tools created with entertainment or profit in mind, YouTube can now be easily and usefully adopted by instructors for educational purposes, and indeed many professors use YouTube in their classroom teaching already (Brooks, 2000. This is especially true for passive uses of YouTube; watching videos that are already online and using them in the classroom experience to support a concept and provide another mechanism for students to connect with the topics. It is fruitful to consider Bloom's Taxonomy of Educational Objectives (Bloom & Krathwohl, 1956 when employing video or any media in the classroom to maximize the intentionality of teaching and learning. The use of video for demonstration or modeling corresponds well to Blooms levels of Knowledge, Comprehension, and Application; while case studies offer a chance to demonstrate Analysis and Synthesis, and perhaps even Evaluation, when comparing a video to information from a text book or other content.

Velthuis, Floor; Varpio, Lara; Helmich, Esther; Dekker, Hanke; Jaarsma, A Debbie C

2018-02-06

Changing an undergraduate medical curriculum is a recurring, high-stakes undertaking at medical schools. This study aimed to explore how people leading major curriculum changes conceived of the process of enacting change and the strategies they relied on to succeed in their efforts. The first author individually interviewed nine leaders who were leading or had led the most recent undergraduate curriculum change in one of the eight medical schools in the Netherlands. Interviews were between December 2015 and April 2016, using a semi-structured interview format. Data analysis occurred concurrently with data collection, with themes being constructed inductively from the data. Leaders conceived of curriculum change as a dynamic, complex process. They described three major challenges they had to deal with while navigating this process: the large number of stakeholders championing a multitude of perspectives, dealing with resistance, and steering the change process. Additionally, strategies for addressing these challenges were described. The authors identified an underlying principle informing the work of these leaders: being and remaining aware of emerging situations, and carefully constructing strategies for ensuring the intended outcomes were reached and contributed to the progress of the change process. This empirical, descriptive study enriches the understanding of how institutional leaders navigate the complexities of major medical curriculum changes. The insights serve as a foundation for training and coaching future change leaders. To broaden the understanding of curriculum change processes, future studies could investigate the processes through alternative stakeholder perspectives.Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a "work of the United States Government" for which copyright protection under Title 17 of the United States Code is not available.

Patanwala, Asad E; Erstad, Brian L; Murphy, John E

To evaluate the extent of student use of flipped classroom videos. This was a cross-sectional study conducted in a college of pharmacy therapeutics course in the Unites States. In one section of the course (four sessions) all content was provided in the form of lecture videos that students had to watch prior to class. Class time was spent discussing patient cases. For half of the sessions, there was an electronic quiz due prior to class. The outcome measure was video view time in minutes. Adequate video view time was defined as viewing ≥75% of total video duration. Video view time was compared with or without quizzes using the Wilcoxon signed-rank test. There were 100 students in the class and all were included in the study. Overall, 74 students had adequate video view time prior to session 1, which decreased to 53 students for session 2, 53 students for session 3, and 36 students for session 4. Median video view time was greater when a quiz was required [80 minutes (IQR: 38-114) versus 69 minutes (IQR: 3-105), p flipped classroom is low and decreases with time. Preparation is higher when there is a quiz required. Copyright © 2016 Elsevier Inc. All rights reserved.

Clinical medical sciences for undergraduate dental students in the United Kingdom and Ireland - a curriculum.

LENUS (Irish Health Repository)

Mighell, A J

2011-08-01

The technical aspects of dentistry need to be practised with insight into the spectrum of human diseases and illnesses and how these impact upon individuals and society. Application of this insight is critical to decision-making related to the planning and delivery of safe and appropriate patient-centred healthcare tailored to the needs of the individual. Provision for the necessary training is included in undergraduate programmes, but in the United Kingdom and Ireland there is considerable variation between centres without common outcomes. In 2009 representatives from 17 undergraduate dental schools in the United Kingdom and Ireland agreed to move towards a common, shared approach to meet their own immediate needs and that might also be of value to others in keeping with the Bologna Process. To provide a clear identity the term \\'Clinical Medical Sciences in Dentistry\\' was agreed in preference to other names such as \\'Human Disease\\' or \\'Medicine and Surgery\\'. The group was challenged to define consensus outcomes. Contemporary dental education documents informed, but did not drive the process. The consensus curriculum for undergraduate Clinical Medical Sciences in Dentistry teaching agreed by the participating centres is reported. Many of the issues are generic and it includes elements that are likely to be applicable to others. This document will act as a focus for a more unified approach to the outcomes required by graduates of the participating centres and act as a catalyst for future developments that ultimately aim to enhance the quality of patient care.

The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years. (c) 2016 APA, all rights reserved).

Alcohol education and training in pre-registration nursing: a national survey to determine curriculum content in the United Kingdom (UK).

Holloway, Aisha S; Webster, Brian J

2013-09-01

Alcohol-related harm impacts significantly on the health of the population. Nurses are often among the first health professionals that many patients with alcohol-related problems come into contact with and have been identified as playing a key role but may be ill-prepared to respond. Future nurses need to have the skills, knowledge and clinical confidence to respond to patients suffering from alcohol-related harm. A pre-registration curriculum that ensures a nursing workforce fit for practice in responding to alcohol-related harm is necessary. To determine the level of alcohol education and training content in the pre-registration curriculum for nursing in the United Kingdom (UK). To establish whether there are variations in the pre-registration curriculum content across the UK. A descriptive study. All 68 UK Higher Education Institutions offering a total of 111 pre-registration courses for nurses were invited to participate in the study. Twenty nine completed questionnaires were returned, a response rate of 26%. The largest number of identified responders were from England (n=15), with 3 from Scotland and 1 each from Wales and Northern Ireland. Nine Universities chose not to identify themselves. An online semi-structured questionnaire survey was used to collect the study data. Teaching of alcohol and alcohol related harm was mainly delivered during the second year of a pre-registration nursing programme provided mainly to adult and mental health students. Overall, the majority of alcohol related content that is provided within the responding pre-registration nursing courses relates to biophysiology, aetiology, and pharmacological and non-pharmacological interventions. This study highlights the need for a greater and more relevant focus of alcohol education to pre-registration nursing students of all fields of practice incorporating an integrated approach across all years of study.

2007-12-01

In the spirit of collaboration and reciprocity, James Rattling Leaf of Sinte Gleska University on the Rosebud Reservation of South Dakota will present recent developments, experiences, insights and a vision for education in Indian Country. As a thirty-year young institution, Sinte Gleska University is founded by a strong vision of ancestral leadership and the values of the Lakota Way of Life. Sinte Gleska University (SGU) has initiated the development of a Geospatial Education Curriculum project. NativeView: A Geospatial Curriculum for Native Nation Building is a two-year project that entails a disciplined approach towards the development of a relevant Geospatial academic curriculum. This project is designed to meet the educational and land management needs of the Rosebud Lakota Tribe through the utilization of Geographic Information Systems (GIS), Remote Sensing (RS) and Global Positioning Systems (GPS). In conjunction with the strategy and progress of this academic project, a formal presentation and demonstration of the SGU based Geospatial software RezMapper software will exemplify an innovative example of state of the art information technology. RezMapper is an interactive CD software package focused toward the 21 Lakota communities on the Rosebud Reservation that utilizes an ingenious concept of multimedia mapping and state of the art data compression and presentation. This ongoing development utilizes geographic data, imagery from space, historical aerial photography and cultural features such as historic Lakota documents, language, song, video and historical photographs in a multimedia fashion. As a tangible product, RezMapper will be a project deliverable tool for use in the classroom and to a broad range of learners.

Dynamic study of DSA by video-densitometry

International Nuclear Information System (INIS)

Imamura, Keiko; Tsukamoto, Hiroshi; Ashida, Hiroshi; Ishikawa, Tohru; Fujii, Masamichi; Uji, Teruyuki

1985-01-01

A system was developed for the dynamic study of DSA by video-densitometric technique. As subtraction images are stored to VTR in our DSA examinations, a frame counter was designed to select images on VTR at an arbitrary interval. ROI setting and video-densitometry were performed using a TV image processor and its host computer. Images were sampled at the rate of 3 frames per second, and clear time-density curves were obtained from brain DSA examinations. Although it takes about 30 minutes to analyse one examination, it is also possible to analyse previous data stored on VTR. For DSA systems having no additional digital storage unit, this method will be helpful. Reduction in image quality through VTR storage had no problem in video-densitometry. Phantom studies have been made concerning the temporal variation of the image brightness during the 20 second-exposure and also the effect of the subjects thickness on the contrast. Filtering for low-grade averaging is preferable for dynamic studies. (author)

Sociology of Hidden Curriculum

Alireza Moradi

2017-06-01

Full Text Available This paper reviews the concept of hidden curriculum in the sociological theories and wants to explain sociological aspects of formation of hidden curriculum. The main question concentrates on the theoretical approaches in which hidden curriculum is explained sociologically.For this purpose it was applied qualitative research methodology. The relevant data include various sociological concepts and theories of hidden curriculum collected by the documentary method. The study showed a set of rules, procedures, relationships and social structure of education have decisive role in the formation of hidden curriculum. A hidden curriculum reinforces by existed inequalities among learners (based on their social classes or statues. There is, in fact, a balance between the learner's "knowledge receptions" with their "inequality proportion".The hidden curriculum studies from different major sociological theories such as Functionalism, Marxism and critical theory, Symbolic internationalism and Feminism. According to the functionalist perspective a hidden curriculum has a social function because it transmits social values. Marxists and critical thinkers correlate between hidden curriculum and the totality of social structure. They depicts that curriculum prepares learners for the exploitation in the work markets. Symbolic internationalism rejects absolute hegemony of hidden curriculum on education and looks to the socialization as a result of interaction between learner and instructor. Feminism theory also considers hidden curriculum as a vehicle which legitimates gender stereotypes.

Individualising Media Practice Education Using a Feedback Loop and Instructional Videos Within an eLearning Environment.

Directory of Open Access Journals (Sweden)

Trevor Harris

2012-06-01

Full Text Available This paper explores the development and impact of the author’s TELE (Technology Enhanced Learning Environment action research project for individualising media practice education. The latest iteration of different classroom methodologies being employed to develop high-level skills in media production, the author has combined an interactive eLearning approach with instructional videos and, crucially, an individual feedback loop in order to widen access to the curriculum and create a more efficient teaching and learning environment. The focus therefore is on student engagement and organisational efficiencies as a result of the research. It should be noted that there has been no funding attached to this work, nor are there any institutional imperatives or other stakeholder involvement in this research. This project has been undertaken by the author as an evolutionary development of the various methodologies developed, cognisant of the increased technology literacy of the student cohort. The educational benefit of bringing video instruction into the curriculum as part of the project is examined as a creative pedagogy of direct benefit to students rather than as a subliminal marketing tool that other systems are often used for. Over 16K words of written data was collected during the project, and this is analysed both quantitatively and qualitatively with reference to the initial objectives of the research

Holovideo: Real-time 3D range video encoding and decoding on GPU

Science.gov (United States)

Karpinsky, Nikolaus; Zhang, Song

2012-02-01

We present a 3D video-encoding technique called Holovideo that is capable of encoding high-resolution 3D videos into standard 2D videos, and then decoding the 2D videos back into 3D rapidly without significant loss of quality. Due to the nature of the algorithm, 2D video compression such as JPEG encoding with QuickTime Run Length Encoding (QTRLE) can be applied with little quality loss, resulting in an effective way to store 3D video at very small file sizes. We found that under a compression ratio of 134:1, Holovideo to OBJ file format, the 3D geometry quality drops at a negligible level. Several sets of 3D videos were captured using a structured light scanner, compressed using the Holovideo codec, and then uncompressed and displayed to demonstrate the effectiveness of the codec. With the use of OpenGL Shaders (GLSL), the 3D video codec can encode and decode in realtime. We demonstrated that for a video size of 512×512, the decoding speed is 28 frames per second (FPS) with a laptop computer using an embedded NVIDIA GeForce 9400 m graphics processing unit (GPU). Encoding can be done with this same setup at 18 FPS, making this technology suitable for applications such as interactive 3D video games and 3D video conferencing.

Investigating the Role of the Teacher in Science Curriculum: New Evidence for an Old Debate

Science.gov (United States)

Penuel, W.; McAuliffe, C.; McWilliams, H.

2007-12-01

It is widely believed that teachers need high-quality curriculum materials to improve teaching and learning. Professional development designs differ, however, in whether they emphasize preparing teachers to use expert- designed curricula or preparing teachers with the tools needed to design and implement high-quality science units themselves. Evidence exists for the effectiveness of providing teachers with training in how to implement expert-designed curricula (Bredderman, 1983; Shymansky, Hedges, & Woodworth, 1990; Weinstein, Boulanger, & Walberg, 1982) and for providing teachers with professional development aimed at preparing teachers to design instruction and assessments (Black & Harrison, 2001; Shepard, 1997; Sneider, Adams, Ibanez, Templeton, & Porter, 1996). However, no studies, however, have compared explicitly these different approaches to preparing teachers to plan and enact instruction in science. The Transforming Instruction by Design in Earth Science (TIDES) project is an experimental study comparing the efficacy of three different approaches to professional development. The approaches differ with respect to the role that teachers are expected to play in curriculum. In one condition (Earth Science by Design), teachers learn how to design curriculum units in Earth science. In a second condition (Investigating Earth Systems), teachers learn how to adopt and implement curriculum materials developed by experts. In the third condition (Hybrid), teachers learn a principled approach to adapt expert-developed curriculum materials. The TIDES study is examining the impacts of each of the approaches to professional development on instructional planning and on the quality of assignments and assessments they give to students. We measured impacts on instructional planning using an end-of-unit questionnaire that focused on changes to teachers" overall approach to planning units of instruction, their strategies for organizing assignment, and materials they use in

2016-07-10

We propose a practical system that can effectively mix the depth data of real and virtual objects by using a Z buffer and can quickly generate digital mixed reality video holograms by using multiple graphic processing units (GPUs). In an experiment, we verify that real objects and virtual objects can be merged naturally in free viewing angles, and the occlusion problem is well handled. Furthermore, we demonstrate that the proposed system can generate mixed reality video holograms at 7.6 frames per second. Finally, the system performance is objectively verified by users' subjective evaluations.

Mathews, Christine L; Morrell, Holly E R; Molle, Jon E

2018-06-06

Up to 23% of people who play video games report symptoms of addiction. Individuals with attention deficit hyperactivity disorder (ADHD) may be at increased risk for video game addiction, especially when playing games with more reinforcing properties. The current study tested whether level of video game reinforcement (type of game) places individuals with greater ADHD symptom severity at higher risk for developing video game addiction. Adult video game players (N = 2,801; Mean age = 22.43, SD = 4.70; 93.30% male; 82.80% Caucasian) completed an online survey. Hierarchical multiple linear regression analyses were used to test type of game, ADHD symptom severity, and the interaction between type of game and ADHD symptomatology as predictors of video game addiction severity, after controlling for age, gender, and weekly time spent playing video games. ADHD symptom severity was positively associated with increased addiction severity (b = .73 and .68, ps .05. The relationship between ADHD symptom severity and addiction severity did not depend on the type of video game played or preferred most, ps > .05. Gamers who have greater ADHD symptom severity may be at greater risk for developing symptoms of video game addiction and its negative consequences, regardless of type of video game played or preferred most. Individuals who report ADHD symptomatology and also identify as gamers may benefit from psychoeducation about the potential risk for problematic play.

Real-time unmanned aircraft systems surveillance video mosaicking using GPU

Science.gov (United States)

Camargo, Aldo; Anderson, Kyle; Wang, Yi; Schultz, Richard R.; Fevig, Ronald A.

2010-04-01

Digital video mosaicking from Unmanned Aircraft Systems (UAS) is being used for many military and civilian applications, including surveillance, target recognition, border protection, forest fire monitoring, traffic control on highways, monitoring of transmission lines, among others. Additionally, NASA is using digital video mosaicking to explore the moon and planets such as Mars. In order to compute a "good" mosaic from video captured by a UAS, the algorithm must deal with motion blur, frame-to-frame jitter associated with an imperfectly stabilized platform, perspective changes as the camera tilts in flight, as well as a number of other factors. The most suitable algorithms use SIFT (Scale-Invariant Feature Transform) to detect the features consistent between video frames. Utilizing these features, the next step is to estimate the homography between two consecutives video frames, perform warping to properly register the image data, and finally blend the video frames resulting in a seamless video mosaick. All this processing takes a great deal of resources of resources from the CPU, so it is almost impossible to compute a real time video mosaic on a single processor. Modern graphics processing units (GPUs) offer computational performance that far exceeds current CPU technology, allowing for real-time operation. This paper presents the development of a GPU-accelerated digital video mosaicking implementation and compares it with CPU performance. Our tests are based on two sets of real video captured by a small UAS aircraft; one video comes from Infrared (IR) and Electro-Optical (EO) cameras. Our results show that we can obtain a speed-up of more than 50 times using GPU technology, so real-time operation at a video capture of 30 frames per second is feasible.

Enhancement system of nighttime infrared video image and visible video image

Wang, Yue; Piao, Yan

2016-11-01

Visibility of Nighttime video image has a great significance for military and medicine areas, but nighttime video image has so poor quality that we can't recognize the target and background. Thus we enhance the nighttime video image by fuse infrared video image and visible video image. According to the characteristics of infrared and visible images, we proposed improved sift algorithm andαβ weighted algorithm to fuse heterologous nighttime images. We would deduced a transfer matrix from improved sift algorithm. The transfer matrix would rapid register heterologous nighttime images. And theαβ weighted algorithm can be applied in any scene. In the video image fusion system, we used the transfer matrix to register every frame and then used αβ weighted method to fuse every frame, which reached the time requirement soft video. The fused video image not only retains the clear target information of infrared video image, but also retains the detail and color information of visible video image and the fused video image can fluency play.

Leisure tourism is an indispensable activity in urban people's life. Due to the popularity of intelligent mobile devices, a large number of photos and videos are recorded during a trip. Therefore, the ability to vividly and interestingly display these media data is a useful technique. In this paper, we propose SnapVideo, a new method that intelligently converts a personal album describing of a trip into a comprehensive, aesthetically pleasing, and coherent video clip. The proposed framework contains three main components. The scenic spot identification model first personalizes the video clips based on multiple prespecified audience classes. We then search for some auxiliary related videos from YouTube 1 according to the selected photos. To comprehensively describe a scenery, the view generation module clusters the crawled video frames into a number of views. Finally, a probabilistic model is developed to fit the frames from multiple views into an aesthetically pleasing and coherent video clip, which optimally captures the semantics of a sightseeing trip. Extensive user studies demonstrated the competitiveness of our method from an aesthetic point of view. Moreover, quantitative analysis reflects that semantically important spots are well preserved in the final video clip. 1 https://www.youtube.com/.

Full Text Available [english] Background: Within the Bologna reform, a longitudinal curriculum of “social and communicative competencies” (SOKO was implemented into the new Bachelor-Master structure of undergraduate medical education in Basel (Switzerland. Project description: The aim of the SOKO curriculum is to enable students to use techniques of patient-centred communication to elicit and provide information to patients in order to involve them as informed partners in decision making processes. The SOKO curriculum consists of 57 lessons for the individual student from the first bachelor year to the first master year. Teaching encompasses lectures and small group learning. Didactic methods include role play, video feedback, and consultations with simulated and real patients. Summative assessment takes place in objective structured clinical examinations (OSCE. Conclusion: In Basel, a longitudinal SOKO curriculum based on students’ cumulative learning was successfully implemented. Goals and contents were coordinated with the remaining curriculum and are regularly assessed in OSCEs. At present, most of the workload rests on the shoulders of the department of psychosomatic medicine at the university hospital. For the curriculum to be successful in the long-term, sustainable structures need to be instituted at the medical faculty and the university hospital to guarantee high quality teaching and assessment.[german] Hintergrund: Mit der Umstellung auf die Bachelor-/Masterstruktur wurde in Basel (Schweiz ein longitudinales Curriculum „soziale und Kommunikative Kompetenzen“ (SOKO in das Medizinstudium implementiert.

It is difficult to provide real-world learning experiences for students to master clinical and communication skills. The purpose of this paper is to describe a novel instructional method using self- and peer-assessment, reflection, and technology to help students develop effective interpersonal and clinical skills. The teaching method is described by the constructivist learning theory and incorporates the use of educational technology. The learning activities were incorporated into the pre-clinical didactic curriculum. The students participated in two video-recording assignments and performed self-assessments on each and had a peer-assessment on the second video-recording. The learning activity was evaluated through the self- and peer-assessments and an instructor-designed survey. This evaluation identified several themes related to the assignment, student performance, clinical behaviors and establishing rapport. Overall the students perceived that the learning activities assisted in the development of clinical and communication skills prior to direct patient care. The use of video recordings of a simulated history and examination is a unique learning activity for preclinical PT students in the development of clinical and communication skills.

Surgical expertise demands technical and nontechnical skills. Traditionally, surgical trainees acquired these skills in the operating room; however, operative time for residents has decreased with duty hour restrictions. As in other professions, video analysis may help maximize the learning experience. To develop and evaluate a postoperative video-based coaching intervention for residents. In this mixed methods analysis, 10 senior (postgraduate year 4 and 5) residents were videorecorded operating with an attending surgeon at an academic tertiary care hospital. Each video formed the basis of a 1-hour one-on-one coaching session conducted by the operative attending; although a coaching framework was provided, participants determined the specific content collaboratively. Teaching points were identified in the operating room and the video-based coaching sessions; iterative inductive coding, followed by thematic analysis, was performed. Teaching points made in the operating room were compared with those in the video-based coaching sessions with respect to initiator, content, and teaching technique, adjusting for time. Among 10 cases, surgeons made more teaching points per unit time (63.0 vs 102.7 per hour) while coaching. Teaching in the video-based coaching sessions was more resident centered; attendings were more inquisitive about residents' learning needs (3.30 vs 0.28, P = .04), and residents took more initiative to direct their education (27% [198 of 729 teaching points] vs 17% [331 of 1977 teaching points], P based coaching is a novel and feasible modality for supplementing intraoperative learning. Objective evaluation demonstrates that video-based coaching may be particularly useful for teaching higher-level concepts, such as decision making, and for individualizing instruction and feedback to each resident.

Full Text Available The aim of this paper is to present video quality prediction models for objective non-intrusive, prediction of H.264 encoded video for all content types combining parameters both in the physical and application layer over Universal Mobile Telecommunication Systems (UMTS networks. In order to characterize the Quality of Service (QoS level, a learning model based on Adaptive Neural Fuzzy Inference System (ANFIS and a second model based on non-linear regression analysis is proposed to predict the video quality in terms of the Mean Opinion Score (MOS. The objective of the paper is two-fold. First, to find the impact of QoS parameters on end-to-end video quality for H.264 encoded video. Second, to develop learning models based on ANFIS and non-linear regression analysis to predict video quality over UMTS networks by considering the impact of radio link loss models. The loss models considered are 2-state Markov models. Both the models are trained with a combination of physical and application layer parameters and validated with unseen dataset. Preliminary results show that good prediction accuracy was obtained from both the models. The work should help in the development of a reference-free video prediction model and QoS control methods for video over UMTS networks.

Leadership and management are two expected features and competencies for general practitioners (GPs). The purpose of this study was leadership and management curriculum planning for GPs which was performed based on Kern's curriculum planning cycle. This study was conducted in 2011- 2012 in Iran using an explanatory mixed-methods approach. It was conducted through an initial qualitative phase using two focus group discussions and 28 semi-structured interviews with key informants to capture their experiences and viewpoints about the necessity of management courses for undergraduate medical students, goals, objectives, and educational strategies according to Kern's curriculum planning cycle. The data was used to develop a questionnaire to be used in a quantitative written survey. Results of these two phases and that of the review of medical curriculum in other countries and management curriculum of other medical disciplines in Iran were used in management and leadership curriculum planning. In the qualitative phase, purposeful sampling and content analysis with constant comparison based on Strauss and Corbin's method were used; descriptive and analytic tests were used for quantitative data by SPSS version 14. In the qualitatively stage of  this research, 6 main categories including the necessity of management course, features and objectives of management curriculum, proper educational setting, educational methods and strategies, evolutionary method and feedback result were determined. In the quantitatively stage of the research, from the viewpoints of 51.6% of 126 units of research who filled out the questionnaire, ranked high necessary of management courses. The coordination of care and clinical leadership was determined as the most important role for GPs with a mean of 6.2 from sample viewpoint. Also, team working and group dynamics had the first priority related to the principles and basics of management with a mean of 3.59. Other results were shown in the paper

A video authentication technique

International Nuclear Information System (INIS)

Johnson, C.S.

1987-01-01

Unattended video surveillance systems are particularly vulnerable to the substitution of false video images into the cable that connects the camera to the video recorder. New technology has made it practical to insert a solid state video memory into the video cable, freeze a video image from the camera, and hold this image as long as desired. Various techniques, such as line supervision and sync detection, have been used to detect video cable tampering. The video authentication technique described in this paper uses the actual video image from the camera as the basis for detecting any image substitution made during the transmission of the video image to the recorder. The technique, designed for unattended video systems, can be used for any video transmission system where a two-way digital data link can be established. The technique uses similar microprocessor circuitry at the video camera and at the video recorder to select sample points in the video image for comparison. The gray scale value of these points is compared at the recorder controller and if the values agree within limits, the image is authenticated. If a significantly different image was substituted, the comparison would fail at a number of points and the video image would not be authenticated. The video authentication system can run as a stand-alone system or at the request of another system

Surveillance video service (SVS) is one of the most important services provided in a smart city. It is very important for the utilization of SVS to provide design efficient surveillance video analysis techniques. Key frame extraction is a simple yet effective technique to achieve this goal. In surveillance video applications, key frames are typically used to summarize important video content. It is very important and essential to extract key frames accurately and efficiently. A novel approach is proposed to extract key frames from traffic surveillance videos based on GPU (graphics processing units) to ensure high efficiency and accuracy. For the determination of key frames, motion is a more salient feature in presenting actions or events, especially in surveillance videos. The motion feature is extracted in GPU to reduce running time. It is also smoothed to reduce noise, and the frames with local maxima of motion information are selected as the final key frames. The experimental results show that this approach can extract key frames more accurately and efficiently compared with several other methods.

In the United States, prostate cancer is the most common type of cancer in men after skin cancer. There is a paucity of research devoted to the types of prostate cancer information available on social media outlets. YouTube TM is a widely used video sharing website, which is emerging as commonplace for information related to health. The purpose of this study was to describe the most widely viewed YouTube TM videos related to prostate cancer. The 100 videos were watched a total of 50,278,770 times. The majority of videos were uploaded by consumers (45.0%) and medical or government professionals (30%). The purpose of most videos (78.0%) was to provide information, followed by discussions of prostate cancer treatment (51%) and prostate-specific antigen testing and routine screening (26%). All videos uploaded by medical and government professionals and 93.8% of videos uploaded by news sources provided information compared with about two thirds of consumer and less than one half of commercial and advertisement videos (p < .001). As society becomes increasingly technology-based, there is a need to help consumers acquire knowledge and skills to identify credible information to help inform their decisions. © The Author(s) 2016.

Ranking Highlights in Personal Videos by Analyzing Edited Videos.

Sun, Min; Farhadi, Ali; Chen, Tseng-Hung; Seitz, Steve

2016-11-01

We present a fully automatic system for ranking domain-specific highlights in unconstrained personal videos by analyzing online edited videos. A novel latent linear ranking model is proposed to handle noisy training data harvested online. Specifically, given a targeted domain such as "surfing," our system mines the YouTube database to find pairs of raw and their corresponding edited videos. Leveraging the assumption that an edited video is more likely to contain highlights than the trimmed parts of the raw video, we obtain pair-wise ranking constraints to train our model. The learning task is challenging due to the amount of noise and variation in the mined data. Hence, a latent loss function is incorporated to mitigate the issues caused by the noise. We efficiently learn the latent model on a large number of videos (about 870 min in total) using a novel EM-like procedure. Our latent ranking model outperforms its classification counterpart and is fairly competitive compared with a fully supervised ranking system that requires labels from Amazon Mechanical Turk. We further show that a state-of-the-art audio feature mel-frequency cepstral coefficients is inferior to a state-of-the-art visual feature. By combining both audio-visual features, we obtain the best performance in dog activity, surfing, skating, and viral video domains. Finally, we show that impressive highlights can be detected without additional human supervision for seven domains (i.e., skating, surfing, skiing, gymnastics, parkour, dog activity, and viral video) in unconstrained personal videos.

Video processing for human perceptual visual quality-oriented video coding.

Science.gov (United States)

Oh, Hyungsuk; Kim, Wonha

2013-04-01

We have developed a video processing method that achieves human perceptual visual quality-oriented video coding. The patterns of moving objects are modeled by considering the limited human capacity for spatial-temporal resolution and the visual sensory memory together, and an online moving pattern classifier is devised by using the Hedge algorithm. The moving pattern classifier is embedded in the existing visual saliency with the purpose of providing a human perceptual video quality saliency model. In order to apply the developed saliency model to video coding, the conventional foveation filtering method is extended. The proposed foveation filter can smooth and enhance the video signals locally, in conformance with the developed saliency model, without causing any artifacts. The performance evaluation results confirm that the proposed video processing method shows reliable improvements in the perceptual quality for various sequences and at various bandwidths, compared to existing saliency-based video coding methods.

Marulcu, Ismail; Barnett, Michael

2016-01-01

Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it. Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students' science content learning of simple machines. Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups' scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group's pre- and post-scores by using paired t-tests. Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions. Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students' science content learning.

No Reference Video-Quality-Assessment Model for Monitoring Video Quality of IPTV Services

Science.gov (United States)

Yamagishi, Kazuhisa; Okamoto, Jun; Hayashi, Takanori; Takahashi, Akira

Service providers should monitor the quality of experience of a communication service in real time to confirm its status. To do this, we previously proposed a packet-layer model that can be used for monitoring the average video quality of typical Internet protocol television content using parameters derived from transmitted packet headers. However, it is difficult to monitor the video quality per user using the average video quality because video quality depends on the video content. To accurately monitor the video quality per user, a model that can be used for estimating the video quality per video content rather than the average video quality should be developed. Therefore, to take into account the impact of video content on video quality, we propose a model that calculates the difference in video quality between the video quality of the estimation-target video and the average video quality estimated using a packet-layer model. We first conducted extensive subjective quality assessments for different codecs and video sequences. We then model their characteristics based on parameters related to compression and packet loss. Finally, we verify the performance of the proposed model by applying it to unknown data sets different from the training data sets used for developing the model.

We currently live in a world filled with videos. There are videos on YouTube, feature movies and even videos recorded with our own cameras and smartphones. These videos present an excellent opportunity to not only explore physical concepts, but also inspire others to investigate physics ideas. With video analysis, we can explore the fantasy world in science-fiction films. We can also look at online videos to determine if they are genuine or fake. Video analysis can be used in the introductory physics lab and it can even be used to explore the make-believe physics embedded in video games. This book covers the basic ideas behind video analysis along with the fundamental physics principles used in video analysis. The book also includes several examples of the unique situations in which video analysis can be used.

Full Text Available The world is not just connected; it is hyper-connected. The global flow of ideas, technology, and people are at unmatched levels in history. More classrooms are becoming cosmopolitan centers composed of students with multicultural backgrounds. However, United States public education in this hyper-connected world puts emphasis on standardization and accountability. By doing so, schools driven by federal initiatives fail in helping students to become worldly citizens. Students and teachers are derived of room for creativity or new multicultural possibilities. Hence, this paper intends to develop a theoretical framework for curriculum in the hyper-connected world, aptly named “hyper-curriculum.”

Illustrating Geology With Customized Video in Introductory Geoscience Courses

Magloughlin, J. F.

2008-12-01

For the past several years, I have been creating short videos for use in large-enrollment introductory physical geology classes. The motivation for this project included 1) lack of appropriate depth in existing videos, 2) engagement of non-science students, 3) student indifference to traditional textbooks, 4) a desire to share the visual splendor of geology through virtual field trips, and 5) a desire to meld photography, animation, narration, and videography in self-contained experiences. These (HD) videos are information-intensive but short, allowing a focus on relatively narrow topics from numerous subdisciplines, incorporation into lectures to help create variety while minimally interrupting flow and holding students' attention, and manageable file sizes. Nearly all involve one or more field locations, including sites throughout the western and central continental U.S., as well as Hawaii, Italy, New Zealand, and Scotland. The limited scope of the project and motivations mentioned preclude a comprehensive treatment of geology. Instead, videos address geologic processes, locations, features, and interactions with humans. The videos have been made available via DVD and on-line streaming. Such a project requires an array of video and audio equipment and software, a broad knowledge of geology, very good computing power, adequate time, creativity, a substantial travel budget, liability insurance, elucidation of the separation (or non-separation) between such a project and other responsibilities, and, preferably but not essentially, the support of one's supervisor or academic unit. Involving students in such projects entails risks, but involving necessary technical expertise is virtually unavoidable. In my own courses, some videos are used in class and/or made available on-line as simply another aspect of the educational experience. Student response has been overwhelmingly positive, particularly when expectations of students regarding the content of the videos is made

2014-07-01

Hypertension (HTN) is a prevalent and growing public health problem in the United States and worldwide. Video sharing Web sites such as YouTube could potentially influence patient behaviors via properties of interpersonal and mass media communication. We conducted this cross-sectional study to assess the accuracy and content of YouTube videos on HTN and understand how viewers interact with this online information. We analyzed 209 videos (31.57 hours) of which 63% were classified as useful, 33% as misleading, and 4% represented patient's personal experiences. Number of views per day and "likes" were significantly lower for useful videos. Approximately half the misleading videos contained product advertisements, 70% advocated unproven alternative treatments, and 91% targeted patients. Viewer engagement (number of views) was a poor predictor of usefulness and/or content whereas source of upload, and target audiences were good predictors of usefulness and/or content. Videos uploaded by university channels and/or professional organizations that targeted physicians had a 99.4% (P < .001) probability of being useful whereas videos uploaded by individuals with unknown credentials that targeted patients had a 21.2% (P < .001) probability of being useful. A majority of HTN-related videos on YouTube are useful. Viewer engagement is significantly higher with videos that contain misleading and/or erroneous information in comparison to videos that contain useful information.

Evolution of the Pathology Residency Curriculum

Wesley Y. Naritoku MD, PhD

2016-10-01

Full Text Available The required medical knowledge and skill set for the pathologist of 2020 are different than in 2005. Pathology residency training curriculum must accordingly change to fulfill the needs of these ever-changing requirements. In order to make rational curricular adjustments, it is important for us to know the current trajectory of resident training in pathology—where we have been, what our actual current training curriculum is now—to understand how that might change in anticipation of meeting the needs of a changing patient and provider population and to fit within the evolving future biomedical and socioeconomic health-care setting. In 2013, there were 143 Accreditation Council for Graduate Medical Education-accredited pathology residency training programs in the United States, with approximately 2400 residents. There is diversity among residency training programs not only with respect to the number of residents but also in training venue(s. To characterize this diversity among pathology residency training programs, a curriculum survey was conducted of pathology residency program directors in 2013 and compared with a similar survey taken almost 9 years previously in 2005 to identify trends in pathology residency curriculum. Clinical pathology has not changed significantly in the number of rotations over 9 years; however, anatomic pathology has changed dramatically, with an increase in the number of surgical pathology rotations coupled with a decline in stand-alone autopsy rotations. With ever-expanding medical knowledge that the graduating pathology resident must know, it is necessary to (1 reflect upon what are the critical need subjects, (2 identify areas that have become of lesser importance, and then (3 prioritize training accordingly.

In order to make rational curricular adjustments, it is important for us to know the current trajectory of resident training in pathology—where we have been, what our actual current training curriculum is now—to understand how that might change in anticipation of meeting the needs of a changing patient and provider population and to fit within the evolving future biomedical and socioeconomic health-care setting. In 2013, there were 143 Accreditation Council for Graduate Medical Education-accredited pathology residency training programs in the United States, with approximately 2400 residents. There is diversity among residency training programs not only with respect to the number of residents but also in training venue(s). To characterize this diversity among pathology residency training programs, a curriculum survey was conducted of pathology residency program directors in 2013 and compared with a similar survey taken almost 9 years previously in 2005 to identify trends in pathology residency curriculum. Clinical pathology has not changed significantly in the number of rotations over 9 years; however, anatomic pathology has changed dramatically, with an increase in the number of surgical pathology rotations coupled with a decline in stand-alone autopsy rotations. With ever-expanding medical knowledge that the graduating pathology resident must know, it is necessary to (1) reflect upon what are the critical need subjects, (2) identify areas that have become of lesser importance, and then (3) prioritize training accordingly.

1987-01-01

The Modular Integrated Video System (MIVS) is being developed for the International Atomic Energy Agency (IAEA) for use in facilities where mains power is available and the separation of the Camera and Recording Control Unit is desirable. The system is being developed under the US Program for Technical Assistance to the IAEA Safeguards (POTAS). The MIVS is designed to be a user-friendly system, allowing operation with minimal effort and training. The system software, through the use of a Liquid Crystal Display (LCD) and four soft keys, leads the inspector through the setup procedures to accomplish the intended surveillance or maintenance task. Review of surveillance data is accomplished with the use of a Portable Review Station. This Review Station will aid the inspector in the review process and determine the number of missed video scenes during a surveillance period

REAL TIME SPEED ESTIMATION FROM MONOCULAR VIDEO

2012-07-01

Full Text Available In this paper, detailed studies have been performed for developing a real time system to be used for surveillance of the traffic flow by using monocular video cameras to find speeds of the vehicles for secure travelling are presented. We assume that the studied road segment is planar and straight, the camera is tilted downward a bridge and the length of one line segment in the image is known. In order to estimate the speed of a moving vehicle from a video camera, rectification of video images is performed to eliminate the perspective effects and then the interest region namely the ROI is determined for tracking the vehicles. Velocity vectors of a sufficient number of reference points are identified on the image of the vehicle from each video frame. For this purpose sufficient number of points from the vehicle is selected, and these points must be accurately tracked on at least two successive video frames. In the second step, by using the displacement vectors of the tracked points and passed time, the velocity vectors of those points are computed. Computed velocity vectors are defined in the video image coordinate system and displacement vectors are measured by the means of pixel units. Then the magnitudes of the computed vectors in the image space are transformed to the object space to find the absolute values of these magnitudes. The accuracy of the estimated speed is approximately ±1 – 2 km/h. In order to solve the real time speed estimation problem, the authors have written a software system in C++ programming language. This software system has been used for all of the computations and test applications.

Teacher change and professional development: A case study of teachers engaged in an innovative constructivist science curriculum

Science.gov (United States)

Akura, Okong'o. Gabriel

This study examined both the changes that elementary school teachers experienced when they implemented a reform-based science curriculum and the impact of professional development on this transformation. The research involved a case study of three purposefully selected teachers implementing the Linking Food and the Environment (LIFE) program during the 2002--2003 school year. The LIFE program is a curriculum designed to enhance science literacy among learners from high poverty urban environments. While the study was grounded in the tradition of critical theory (Carspecken, 1996), the theoretical perspective of hermeneutic phenomenology (van Manen, 1990) guided data collection and analysis. Extensive observations of the teachers were made in order to capture and record the teacher change phenomenon. Data were recorded by means of field notes, audio and videotapes, semi-structured interviews, classroom observations, and video Stimulated Recall (SR) interviews. Emerging themes relating to teacher change, knowledge interests, constructivist pedagogy, and professional development illustrated how teachers grapple with various aspects of implementing a reform-based science curriculum. The teachers in this study were similar to those in earlier investigations, which found that sustained professional development programs involving mentoring and constant reflection enable elementary science teachers to change their instructional strategies from the technical-realist orientation towards the practical-hermeneutic and emancipatory-liberatory orientations. The study has implications for science curriculum developers and designers of professional development programs.

Video Self-Modeling: A Promising Strategy for Noncompliant Children.

Science.gov (United States)

Axelrod, Michael I; Bellini, Scott; Markoff, Kimberly

2014-07-01

The current study investigated the effects of a Video Self-Modeling (VSM) intervention on the compliance and aggressive behavior of three children placed in a psychiatric hospital. Each participant viewed brief video clips of himself following simple adult instructions just prior to the school's morning session and the unit's afternoon free period. A multiple baseline design across settings was used to evaluate the effects of the VSM intervention on compliance with staff instructions and aggressive behavior on the hospital unit and in the hospital-based classroom. All three participants exhibited higher levels of compliance and fewer aggressive episodes during the intervention condition, and the effects were generally maintained when the intervention was withdrawn. Hospital staff reported at the conclusion of the study that the VSM intervention was easy to implement and beneficial for all participants. Taken altogether, the results suggest VSM is a promising, socially acceptable, and proactive intervention approach for improving the behavior of noncompliant children. © The Author(s) 2014.

Health issues of the operators on video display units - the consequence of electromagnetic radiation or something else

International Nuclear Information System (INIS)

Brumen, V.; Garaj-Vrhovac, V.; Franekic Colic, J.; Radalj, Z.

2005-01-01

Over the last few decades, video display units (VDUs) have become inevitable in a number of workplaces. This raised a debate on possible health effects of occupational exposure to VDUs. Most frequently reported complaints are eyestrain, bone/muscle disorders and psychological problems related to monotonous, repetitive work. Questions have been raised whether regular exposure to electromagnetic fields generated by the screen could induce cataract. In response to a direct inquiry of VDU operators from a large Croatian company, whether their eye discomforts could be attributed to screen irradiation, we measured electromagnetic fields generated by screens. Measurements were performed using a portable measuring device PMM 8051, serial number 0182 (PMM Costruzioni Elettroniche Centro Misure Radioelettriche s.r. Milan, Italy) with three different probes, with and without a filter. The results showed that screen-generated fields were far bellow the threshold required for a causing a cataract, which overruled the possibility that the actinic effect should produce eye discomfort.(author)

Medical students' perceptions of video-linked lectures and video-streaming

Karen Mattick

2010-12-01

Full Text Available Video-linked lectures allow healthcare students across multiple sites, and between university and hospital bases, to come together for the purposes of shared teaching. Recording and streaming video-linked lectures allows students to view them at a later date and provides an additional resource to support student learning. As part of a UK Higher Education Academy-funded Pathfinder project, this study explored medical students' perceptions of video-linked lectures and video-streaming, and their impact on learning. The methodology involved semi-structured interviews with 20 undergraduate medical students across four sites and five year groups. Several key themes emerged from the analysis. Students generally preferred live lectures at the home site and saw interaction between sites as a major challenge. Students reported that their attendance at live lectures was not affected by the availability of streamed lectures and tended to be influenced more by the topic and speaker than the technical arrangements. These findings will inform other educators interested in employing similar video technologies in their teaching.Keywords: video-linked lecture; video-streaming; student perceptions; decisionmaking; cross-campus teaching.

2017-08-01

Full Text Available In this paper, we present a novel system, inVideo, for automatically indexing and searching videos based on the keywords spoken in the audio track and the visual content of the video frames. Using the highly efficient video indexing engine we developed, inVideo is able to analyze videos using machine learning and pattern recognition without the need for initial viewing by a human. The time-stamped commenting and tagging features refine the accuracy of search results. The cloud-based implementation makes it possible to conduct elastic search, augmented search, and data analytics. Our research shows that inVideo presents an efficient tool in processing and analyzing videos and increasing interactions in video-based online learning environment. Data from a cybersecurity program with more than 500 students show that applying inVideo to current video material, interactions between student-student and student-faculty increased significantly across 24 sections program-wide.

MAC-Layer Active Dropping for Real-Time Video Streaming in 4G Access Networks

KAUST Repository

She, James

2010-12-01

This paper introduces a MAC-layer active dropping scheme to achieve effective resource utilization, which can satisfy the application-layer delay for real-time video streaming in time division multiple access based 4G broadband wireless access networks. When a video frame is not likely to be reconstructed within the application-layer delay bound at a receiver for the minimum decoding requirement, the MAC-layer protocol data units of such video frame will be proactively dropped before the transmission. An analytical model is developed to evaluate how confident a video frame can be delivered within its application-layer delay bound by jointly considering the effects of time-varying wireless channel, minimum decoding requirement of each video frame, data retransmission, and playback buffer. Extensive simulations with video traces are conducted to prove the effectiveness of the proposed scheme. When compared to conventional cross-layer schemes using prioritized-transmission/retransmission, the proposed scheme is practically implementable for more effective resource utilization, avoiding delay propagation, and achieving better video qualities under certain conditions.

2017-01-01

Objective. To develop, implement, and assess whether simulated patient case videos improve students’ understanding of and attitudes toward cross-cultural communication in health care. Design. Third-year pharmacy students (N=159) in a health care communications course participated in a one-hour lecture and two-hour workshop on the topic of cross-cultural communication. Three simulated pharmacist-patient case vignettes highlighting cross-cultural communication barriers, the role of active listening, appropriate use of medical interpreters, and useful models to overcome communication barriers were viewed and discussed in groups of 20 students during the workshop. Assessment. A pre-lecture and post-workshop assessed the effect on students’ understanding of and attitudes toward cross-cultural communication. Understanding of cross-cultural communication concepts increased significantly, as did comfort level with providing cross-cultural care. Conclusion. Use of simulated patient case videos in conjunction with an interactive workshop improved pharmacy students' understanding of and comfort level with cross-cultural communication skills and can be useful tools for cultural competency training in the curriculum.

Thematic curriculum approach

Directory of Open Access Journals (Sweden)

Šefer Jasmina P.

2003-01-01

Full Text Available Thematic curriculum combines disciplines and media. The process is problem-oriented and the scenario most often follows the logic of exploring or storytelling. Those two approaches to teaching are appropriate because they fit into interdisciplinary and creative open-ended problem solving through play, as insisted upon by thematic curriculum. The matrix, where seven types of abilities intersect with five types of problems according to their degree of openness, defines well the outcomes of teaching. However, it did not prove to be suitable for planning the majority of activities in thematic curriculum, for it follows with difficulty the process of exploring or storytelling i.e. it disrupts the subject matter coherence of thematic curriculum. Therefore, it is suggested that matrix should be used for disciplinary curriculum planning but for that of thematic curriculum only in exclusive cases. The matrix should be used primarily as a framework for evaluating the distribution of various types of abilities and problem situations in teaching. The logic of diverse approaches to teaching reflects itself in the manner of planning and organizing the teaching process. Conceptual, visual-graphic, structural and other aids employed during educational process planning should suit the nature of the approach chosen. On the basis of qualitative investigations of educational process, in the present paper considerations are given to various approaches to teaching development of various drafts for the planning of teaching, and recognition of the logic of storytelling and exploring in thematic curriculum.

Video Comparator

International Nuclear Information System (INIS)

Rose, R.P.

1978-01-01

The Video Comparator is a comparative gage that uses electronic images from two sources, a standard and an unknown. Two matched video cameras are used to obtain the electronic images. The video signals are mixed and displayed on a single video receiver (CRT). The video system is manufactured by ITP of Chatsworth, CA and is a Tele-Microscope II, Model 148. One of the cameras is mounted on a toolmaker's microscope stand and produces a 250X image of a cast. The other camera is mounted on a stand and produces an image of a 250X template. The two video images are mixed in a control box provided by ITP and displayed on a CRT. The template or the cast can be moved to align the desired features. Vertical reference lines are provided on the CRT, and a feature on the cast can be aligned with a line on the CRT screen. The stage containing the casts can be moved using a Boeckleler micrometer equipped with a digital readout, and a second feature aligned with the reference line and the distance moved obtained from the digital display

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

Science.gov (United States)

Williams, Glenn L.

1991-12-01

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.

Learning Science Through Digital Video: Views on Watching and Creating Videos

Science.gov (United States)

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.

From Impairment to Empowerment: A Longitudinal Medical School Curriculum on Disabilities.

Sarmiento, Cristina; Miller, Sonya R; Chang, Eleanor; Zazove, Philip; Kumagai, Arno K

2016-07-01

All physicians will care for individuals with disabilities; however, education about disabilities is lacking at most medical schools. Most of the schools that do include such education exclusively teach the medical model, in which disability is viewed as an impairment to be overcome. Disability advocates contest this approach because it overlooks the social and societal contexts of disability. A collaboration between individuals with disabilities, educators, and physicians to design a medical school curriculum on disabilities could overcome these differences. A curriculum on disabilities for first- and second-year medical students was developed during the 2013-2014 academic year and involved a major collaboration between a medical student, medical educators, disability advocates, and academic disability specialists. The guiding principle of the project was the Disability Rights Movement motto, "Nothing about us without us." Two small-group sessions were created, one for each medical school class. They included discussions about different models of disability, video and in-person narratives of individuals with disabilities, and explorations of concepts central to social perceptions of disability, such as power relationships, naming and stigmatization, and disability as identity. According to evaluations conducted after each session, students reported positive feedback about both sessions. Through this curriculum, first- and second-year medical students learned about the obstacles faced by individuals with disabilities and became better equipped to understand and address the concerns, hopes, and societal challenges of their future patients. This inclusive approach may be used to design additional curricula about disabilities for the clinical and postgraduate years.

Epstein, Joel; Noel, Jeffrey; Finnegan, Megan; Watkins, Kate

2016-01-01

Researchers have developed many different computerized interventions designed to teach students about the dangers of substance use. Following in this tradition, we produced a series of video games called Bacon Brains . However, unlike many other programs, ours focused on the "Science of Addiction," providing lessons on how alcohol and other drugs affect the brain. The purpose of this study was to evaluate the effectiveness of our games in teaching students our science-based curriculum. We enrolled over 200 students and randomly assigned them to play our games or a different series of NIDA-produced games. Of the students in the Bacon Brains conditions, half were instructed to play collaboratively and the other half was told to play competitively. Results indicate significantly greater knowledge gains among students in Bacon Brains compared to the existing games (5.01 mean knowledge score difference; [F(1,242)=9.588, p=.002]). Girls demonstrated knowledge gains in both collaborative and competitive conditions, but boys demonstrated similar gains only in the competitive condition. Based on our outcomes, we conclude that video games can serve as an effective method of science instruction. We further discuss the importance of considering gender differences in light of differential response to collaborative vs. competitive learning environments.

The benefits of playing video games.

Science.gov (United States)

Granic, Isabela; Lobel, Adam; Engels, Rutger C M E

2014-01-01

Video games are a ubiquitous part of almost all children's and adolescents' lives, with 97% playing for at least one hour per day in the United States. The vast majority of research by psychologists on the effects of "gaming" has been on its negative impact: the potential harm related to violence, addiction, and depression. We recognize the value of that research; however, we argue that a more balanced perspective is needed, one that considers not only the possible negative effects but also the benefits of playing these games. Considering these potential benefits is important, in part, because the nature of these games has changed dramatically in the last decade, becoming increasingly complex, diverse, realistic, and social in nature. A small but significant body of research has begun to emerge, mostly in the last five years, documenting these benefits. In this article, we summarize the research on the positive effects of playing video games, focusing on four main domains: cognitive, motivational, emotional, and social. By integrating insights from developmental, positive, and social psychology, as well as media psychology, we propose some candidate mechanisms by which playing video games may foster real-world psychosocial benefits. Our aim is to provide strong enough evidence and a theoretical rationale to inspire new programs of research on the largely unexplored mental health benefits of gaming. Finally, we end with a call to intervention researchers and practitioners to test the positive uses of video games, and we suggest several promising directions for doing so.

2004-03-11

Children's exposure to violence in the media remains a source of public health concern; however, violence in video games rated T (for "Teen") by the Entertainment Software Rating Board (ESRB) has not been quantified. To quantify and characterize the depiction of violence and blood in T-rated video games. According to the ESRB, T-rated video games may be suitable for persons aged 13 years and older and may contain violence, mild or strong language, and/or suggestive themes. We created a database of all 396 T-rated video game titles released on the major video game consoles in the United States by April 1, 2001 to identify the distribution of games by genre and to characterize the distribution of content descriptors for violence and blood assigned to these games. We randomly sampled 80 game titles (which included 81 games because 1 title included 2 separate games), played each game for at least 1 hour, and quantitatively assessed the content. Given the release of 2 new video game consoles, Microsoft Xbox and Nintendo GameCube, and a significant number of T-rated video games released after we drew our random sample, we played and assessed 9 additional games for these consoles. Finally, we assessed the content of 2 R-rated films, The Matrix and The Matrix: Reloaded, associated with the T-rated video game Enter the Matrix. Game genre; percentage of game play depicting violence; depiction of injury; depiction of blood; number of human and nonhuman fatalities; types of weapons used; whether injuring characters, killing characters, or destroying objects is rewarded or is required to advance in the game; and content that may raise concerns about marketing T-rated video games to children. Based on analysis of the 396 T-rated video game titles, 93 game titles (23%) received content descriptors for both violence and blood, 280 game titles (71%) received only a content descriptor for violence, 9 game titles (2%) received only a content descriptor for blood, and 14 game titles

Grace, Shamarion Gladys

This is a three-article five chapter doctoral dissertation. The overall purpose of this three-pronged study is to engage a middle school science teacher and students in formal-informal science education within the context of a science standards-based curriculum and Urban Science Center. The goals of the study were: (1) to characterize the conversations of formal and informal science educators as they attempted to implement a standards-based curriculum augmented with science center exhibits; (2) to study the classroom discourse between the teacher and students that foster the development of common knowledge in science and student understanding of the concept of energy before observing science center exhibits on energy; (3) to investigate whether or not a standards-driven, project-based Investigating and Questioning our World through Science and Technology (IQWST) curriculum unit on forms and transformation of energy augmented with science center exhibits had a significant effect on urban African-American seventh grade students' achievement and learning. Overall, the study consisted of a mixed-method approach. Article one consists of a case study featuring semi-structured interviews and field notes. Article two consists of documenting and interpreting teacher-students' classroom discourse. Article three consists of qualitative methods (classroom discussion, focus group interviews, student video creation) and quantitative methods (multiple choice and open-ended questions). Oral discourses in all three studies were audio-recorded and transcribed verbatim. In article one, the community of educators' conversations were critically analyzed to discern the challenges educators encountered when they attempted to connect school curriculum to energy exhibits at the Urban Science Center. The five challenges that characterize the emergence of a third space were as follows: (a) science terminology for lesson focus, (b) "dumb-down" of science exhibits, (c) exploration distracts

Chinese immigrants to North America have substantially higher rates of chronic hepatitis B infection than the general population. One area for strategic development in the field of health education is the design and evaluation of English-as-a-Second language (ESL) curricula. The theoretical perspective of the Health Behavior Framework, results from a community-based survey of Chinese Canadian immigrants with limited English proficiency, and findings from focus groups of ESL instructors as well as Chinese ESL students were used to develop a hepatitis B ESL educational module. This research was conducted in Vancouver, BC. Survey data showed that less than three-fifths of the respondents had been tested for hepatitis B, and documented some important hepatitis B knowledge deficits. Further, only about one-quarter had ever received a physician recommendation for hepatitis B serologic testing. The ESL curriculum aims to both promote hepatitis B testing and improve knowledge, and includes seven different ESL exercises: Warm-up, vocabulary cards, information-gap, video, jigsaw, guided discussion, and problem/advice cards. Our quantitative and qualitative methods for curriculum development could be replicated for other health education topics and in other limited English speaking populations.

This study evaluates whether video-based coaching can enhance laparoscopic surgical skills performance. Many professions utilize coaching to improve performance. The sports industry employs video analysis to maximize improvement from every performance. Laparoscopic novices were baseline tested and then trained on a validated virtual reality (VR) laparoscopic cholecystectomy (LC) curriculum. After competence, subjects were randomized on a 1:1 ratio and each performed 5 VRLCs. After each LC, intervention group subjects received video-based coaching by a surgeon, utilizing an adaptation of the GROW (Goals, Reality, Options, Wrap-up) coaching model. Control subjects viewed online surgical lectures. All subjects then performed 2 porcine LCs. Performance was assessed by blinded video review using validated global rating scales. Twenty subjects were recruited. No significant differences were observed between groups in baseline performance and in VRLC1. For each subsequent repetition, intervention subjects significantly outperformed controls on all global rating scales. Interventions outperformed controls in porcine LC1 [Global Operative Assessment of Laparoscopic Skills: (20.5 vs 15.5; P = 0.011), Objective Structured Assessment of Technical Skills: (21.5vs 14.5; P = 0.001), and Operative Performance Rating System: (26 vs 19.5; P = 0.001)] and porcine LC2 [Global Operative Assessment of Laparoscopic Skills: (28 vs 17.5; P = 0.005), Objective Structured Assessment of Technical Skills: (30 vs 16.5; P < 0.001), and Operative Performance Rating System: (36 vs 21; P = 0.004)]. Intervention subjects took significantly longer than controls in porcine LC1 (2920 vs 2004 seconds; P = 0.009) and LC2 (2297 vs 1683; P = 0.003). Despite equivalent exposure to practical laparoscopic skills training, video-based coaching enhanced the quality of laparoscopic surgical performance on both VR and porcine LCs, although at the expense of increased time. Video-based coaching is a feasible

Hierarchical video summarization

We address the problem of key-frame summarization of vide in the absence of any a priori information about its content. This is a common problem that is encountered in home videos. We propose a hierarchical key-frame summarization algorithm where a coarse-to-fine key-frame summary is generated. A hierarchical key-frame summary facilitates multi-level browsing where the user can quickly discover the content of the video by accessing its coarsest but most compact summary and then view a desired segment of the video with increasingly more detail. At the finest level, the summary is generated on the basis of color features of video frames, using an extension of a recently proposed key-frame extraction algorithm. The finest level key-frames are recursively clustered using a novel pairwise K-means clustering approach with temporal consecutiveness constraint. We also address summarization of MPEG-2 compressed video without fully decoding the bitstream. We also propose efficient mechanisms that facilitate decoding the video when the hierarchical summary is utilized in browsing and playback of video segments starting at selected key-frames.

The Independent Schools Foundation Academy (ISF) in Hong Kong established a sustainability policy in 2015, which explicitly states, "an experimentally integrated, environmentally and ethically sustainable system of science education and conservation practices based on the 2012 Jeju Declaration of the World Conservation Congress will be implemented through the school". ISF Academy is a private Chinese bilingual school in Hong Kong serving over 1500 students K-12, following the framework and curriculum of the International Baccalaureate Organization (IBO). The strategy behind the implementation of this policy includes: development of a scientific sustainable curriculum that is age appropriate; establish a culture of sustainability within the ISF community and beyond to the wider HK community; install sustainable infrastructure that allows students to learn; and learn first hand sustainable living practices. It is well understood that solutions to the environmental challenges facing Hong Kong and our planet will require multiple disciplines. The current sustainability programs at ISF include: a) a whole school aerobic food waste composting system and organic farming, b) energy consumption monitoring of existing buildings, c) upcoming installation of an air pollution monitoring equipment that will correlate with the AQHI data collected by the Hong Kong government, d) a Renewable Energy Education Center (REEC) that will teach students about RE and also produce solar energy for classroom consumption, and e) student lead environmental group that manages the paper and used cooking oil recycling on campus. The Shuyuan Science and Sustainability faculty work closely with classroom teachers to ensure that the above mentioned projects are incorporated into the curriculum throughout the school. Interdisciplinary units (IDU) of study are being developed that encourage faculty and students to work across subject areas. Projects include Personal Projects, Extended Essays

Innovative curriculum designs are vital for effective learning in contemporary nursing education where traditional modes of delivery are not adequate to meet the learning needs of postgraduate students. This instance of postgraduate teaching in a distributed learning environment offered the opportunity to design a flexible learning model for teaching advanced clinical skills. To present a sustainable model for flexible learning that enables specialist nurses to gain postgraduate qualifications without on-campus class attendance by teaching and assessing clinical health care skills in an authentic workplace setting. An action research methodology was used to gather evidence and report on the process of curriculum development of a core unit, Comprehensive Health Assessment (CHA), within 13 different postgraduate speciality courses. Qualitative data was collected from 27 teaching academics, 21 clinical specialist staff, and 7 hospital managers via interviews, focus groups and journal reflections. Evaluations from the initial iteration of CHA from 36 students were obtained. Data was analyzed to develop and evaluate the curriculum design of CHA. The key factors indicated by participants in the curriculum design process were coordination and structuring of teaching and assessment; integration of content development; working with technologies, balancing specialities and core knowledge; and managing induction and expectations. A set of recommendations emerged as a result of the action research process. These included: a constructive alignment approach to curriculum design; the production of a facilitator's guide that specifies expectations and unit information for academic and clinical education staff; an agreed template for content authors; and the inclusion of synchronous communication for real-time online tutoring. The highlight of the project was that it built curriculum design capabilities of clinicians and students which can sustain this alternative model of online

2017-11-01

To examine a possible relationship between exposure to video games/electronic screens and visual issues in children between 3 and 10 years of age. An observational, cross-sectional study of a population of children using video games was employed. All patients between 3 and 10 years of age were recruited at an outpatient unit accredited by the Italian Regional Health Service. Three hundred twenty children (159 boys and 161 girls; mean age = 6.9 ± 2 years) were observed. Ophthalmological examination included assessment of stereoscopic vision on Lang-Stereotests I and II (LANG-STEREOTEST AG, Küsnacht, Switzerland) and identification of the dominant eye using the Dolman method. Furthermore, a questionnaire was used to record asthenopic symptoms and daily exposure to video games and electronic screens. Two groups of children were examined according to the average amount of time spent playing video games daily: children who played video games for less than 30 minutes per day and not every day (control group) and children who played video games for 30 minutes or more every day (video game group). Both groups were then divided into two subgroups: children using other types of electronic screens (eg, televisions, computers, tablets, and smartphones) for less than 3 hours daily (low electronic use subgroup) and children using other types of electronic screens for 3 hours or more per day (high electronic use subgroup). Asthenopia (especially headache, eyelid tic, transient diplopia, and dizziness), absence of fine stereopsis, and refractive errors were statistically more frequent (mainly in the dominant eye) in children in the video game group. These symptoms were frequent and peculiar in the video game group and might be part of a video game vision syndrome that has not been defined yet. It is important to recognize these signs as possible functional disorders to avoid erroneous diagnostic and therapeutic interventions. [J Pediatr Ophthalmol Strabismus. 2017

Seo, Chan-Won; Han, Jong-Ki; Nguyen, Truong Q

2011-08-01

Multimedia data delivered to mobile devices over wireless channels or the Internet are complicated by bandwidth fluctuation and the variety of mobile devices. Scalable video coding has been developed as an extension of H.264/AVC to solve this problem. Since scalable video codec provides various scalabilities to adapt the bitstream for the channel conditions and terminal types, scalable codec is one of the useful codecs for wired or wireless multimedia communication systems, such as IPTV and streaming services. In such scalable multimedia communication systems, video quality fluctuation degrades the visual perception significantly. It is important to efficiently use the target bits in order to maintain a consistent video quality or achieve a small distortion variation throughout the whole video sequence. The scheme proposed in this paper provides a useful function to control video quality in applications supporting scalability, whereas conventional schemes have been proposed to control video quality in the H.264 and MPEG-4 systems. The proposed algorithm decides the quantization parameter of the enhancement layer to maintain a consistent video quality throughout the entire sequence. The video quality of the enhancement layer is controlled based on a closed-form formula which utilizes the residual data and quantization error of the base layer. The simulation results show that the proposed algorithm controls the frame quality of the enhancement layer in a simple operation, where the parameter decision algorithm is applied to each frame.

The use of digital video for science education has become common with the wide availability of video imagery. This study continues research into aspects of using digital video as a primary teaching tool to enhance student learning in undergraduate science courses. Two survey instruments were administered to undergraduate non-science majors. Survey One focused on: a) What science is being learned from watching science videos such as a "YouTube" clip of a volcanic eruption or an informational video on geologic time and b) What are student preferences with regard to their learning (e.g. using video versus traditional modes of delivery)? Survey Two addressed students' perspectives on the storytelling aspect of the video with respect to: a) sustaining interest, b) providing science information, c) style of video and d) quality of the video. 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. The storytelling aspect of each video was also addressed by students. Students watched 15-20 shorter (3-15 minute science videos) created within the last four years. Initial results of this research support that shorter video segments were preferred and the storytelling quality of each video related to student learning.

Vocational high school (Sekolah Menengah Kejuruan / SMK) aims to prepare mid-level skilled labors to work in the industry and are able to create self-employment opportunities. For those reasons, the curriculum in SMK should be based on meeting the needs of the industries and is able to prepare learners to master the competence in accordance with the skills program of their choice. Production based curriculum is the curriculum which the learning process is designed together with the production process or using production process as a learning medium. This approach with the primary intention to introduce students with the real working environment and not merely simulations. In the production-based curriculum implementation model, students are directly involved in the industry through the implementation of industrial working practices, do work on production units in school, and do practical work in school by doing the job as done in the industry by using industry standards machines.

Blending work-integrated learning with distance education in an Australian radiation therapy advanced practice curriculum

International Nuclear Information System (INIS)

Matthews, Kristie; Wright, Caroline; Osborne, Catherine

2014-01-01

Advanced practice for radiation therapists has been a part of the international landscape for several years; however formal implementation into the Australian health care system is yet to happen. Despite this, three short course radiation therapy advanced practitioner programs have been established by an Australian tertiary institution in response to clinical service needs at several organisations. This paper describes the rationale for curriculum design and development of the program materials, the small-scale implementation of the programs at pilot sites, and the evolution of the curriculum to be available to registered radiation therapists nationally. Each program has been designed around a specific clinical role, where flexibility of delivery to busy practitioners was central to the decision to offer them via distance education. The curriculum comprises theoretical units of study which run in parallel to and underpin clinical practice units, where advanced competence in the specific area of practice is overseen by an experienced radiation oncologist mentor. Given the nature of the disparate clinical services requiring an advanced radiation therapy practitioner, the workplace learning component of the course is individually negotiated at a local level. Outcomes suggest that the flexible clinically based training underpinned by a distance education academic curriculum is able to support the development of advanced radiation therapy practitioners responsive to local service need, and ultimately may improve the patient experience

Interdisciplinary Climate Change Curriculum Materials based on the Next Generation Science Standards and The Earth Charter

Science.gov (United States)

Barbosa, A.; Robertson, W. H.

2013-12-01

In the 2012, the National Research Council (NRC) of the National Academies' reported that one of the major issues associated with the development of climate change curriculum was the lack of interdisciplinary materials that also promoted a correlation between science standards and content. Therefore, in order to respond to this need, our group has developed an interdisciplinary climate change curriculum that has had as its fundamental basis the alignment with the guidelines presented by the Next Generation Science Standards (NGSS) and the ones presented by the international document entitled The Earth Charter. In this regards, while the alignment with NGSS disciplinary core ideas, cross-concepts and students' expectations intended to fulfill the need for the development of climate change curriculum activities that were directly associated with the appropriate set of NGSS guidelines, the alignment with The Earth Charter document intended to reinforce the need the for the integration of sociological, philosophical and intercultural analysis of the theme 'climate change'. Additionally, our curriculum was also developed as part of a collaborative project between climate scientists and engineers, who are responsible for the development of a Regional Arctic Simulation Model (RASM). Hence, another important curriculum constituent was the feedback, suggestions and reviews provided by these professionals, who have also contributed to these pedagogical materials' scientific accuracy by facilitating the integration of datasets and visualizations developed by RASM. Furthermore, our group has developed a climate change curriculum for two types of audience: high school and early undergraduate students. Each curriculum unit is divided into modules and each module contains a set of lesson plans. The topics selected to compose each unit and module were designated according to the surveys conducted with scientists and engineers involved with the development of the climate change

Performance Analysis of Video Transmission Using Sequential Distortion Minimization Method for Digital Video Broadcasting Terrestrial

Directory of Open Access Journals (Sweden)

Novita Astin

2016-12-01

Full Text Available This paper presents about the transmission of Digital Video Broadcasting system with streaming video resolution 640x480 on different IQ rate and modulation. In the video transmission, distortion often occurs, so the received video has bad quality. Key frames selection algorithm is flexibel on a change of video, but on these methods, the temporal information of a video sequence is omitted. To minimize distortion between the original video and received video, we aimed at adding methodology using sequential distortion minimization algorithm. Its aim was to create a new video, better than original video without significant loss of content between the original video and received video, fixed sequentially. The reliability of video transmission was observed based on a constellation diagram, with the best result on IQ rate 2 Mhz and modulation 8 QAM. The best video transmission was also investigated using SEDIM (Sequential Distortion Minimization Method and without SEDIM. The experimental result showed that the PSNR (Peak Signal to Noise Ratio average of video transmission using SEDIM was an increase from 19,855 dB to 48,386 dB and SSIM (Structural Similarity average increase 10,49%. The experimental results and comparison of proposed method obtained a good performance. USRP board was used as RF front-end on 2,2 GHz.

Electricity consumption and energy savings potential of video game consoles in the United States

Energy Technology Data Exchange (ETDEWEB)

Hittinger, E.; Mullins, K.A.; Azevedo, I.L. [Department of Engineering and Public Policy, Carnegie Mellon University, Pittsburgh, PA 15213 (United States)

2012-11-15

Total energy consumption of video game consoles has grown rapidly in the past few decades due to rapid increases in market penetration, power consumption of the devices, and increasing usage driven by new capabilities. Unfortunately, studies investigating the energy impacts of these devices have been limited and potential responses, such as ENERGY STAR requirements, have been difficult to define and implement. We estimate that the total electricity consumption of video game consoles in the US was around 11 TWh in 2007 and 16 TWh in 2010 (approximately 1 % of US residential electricity consumption), an increase of almost 50 % in 3 years. However, any estimate of total game console energy consumption is highly uncertain, and we have determined that the key uncertainty is the unknown consumer behavior with regards to powering down the system after use. Even under this uncertainty, we demonstrate that the most effective energy-saving modification is incorporation of a default auto power down feature, which could reduce electricity consumption of game consoles by 75 % (10 TWh reduction of electricity in 2010), saving consumers over USD 1 billion annually in electricity bills. We conclude that using an auto power down feature for game consoles is at least as effective for reducing energy consumption as implementing a strict set of energy efficiency improvements for the devices, is much easier to implement given the nature of the video game console industry, and could be applied retroactively to currently deployed consoles through firmware updates.

We report on one of four undergraduate curriculum units on natural catastrophes that make use of a wide range of geologic and geophysical data sets and data visualization and analysis tools. All units use My World GIS tools, Google Earth, Excel, animations, and video. In the Cascadia case study, students conduct a series of investigations concerning evidence of M9+ earthquakes in the past and evidence of present-day deformation consistent with the likelihood of another such earthquake some time in the future. The unit begins with Native oral traditions that predate European settlement of the region in the mid-18th century that tell of a huge earthquake and accompanying tsunami. The scene shifts to the great M9+ Sumatra earthquake of 2004 as a possible analog. Students analyze GPS and other data related to horizontal and vertical motions accompanying the earthquake. Comparisons of deformation patterns and rupture zone extent among the 2004 M9+ Sumatran, 1960 M9+ Chilean and the 1964 M9+ Alaskan earthquakes are made with a possible Cascadian analog. Students analyze Cascadia GPS data from the Plate Boundary Observatory and investigate strain accumulation patterns consistent with a locked zone at the shallow part of the subduction zone. They then use geologic evidence to evaluate the possibility of great earthquakes in the past. They do this much in the same way that geologists have, noting the distinctive stratigraphic evidence of catastrophic subsidence and tsunami inundation, directly analogous to the effects accompanying the other great earthquakes they have studied. They determine the year, date, and time of the last great earthquake that occurred here, by linking to the Japanese historical record of an "Orphan Tsunami" that devastated Japan in 1700. They note evidence from coastal estuarian stratigraphy and from deep sea cores in the Cascadia Basin of multiple great earthquakes over the last 10,000 years and compute recurrence intervals. They then conduct a

Full Text Available Among Hispanic immigrants in the United States (US, learning English is considered necessary for economic and social achievement. Asa consequence, there is a high demand for English as a Second Language (ESL classes. Despite the recognized benefits of ESL programs,both at the individual and social levels, more research is needed to identify education strategies that effectively promote all aspects of learningEnglish as a second language. This article describes an ESL curriculum that incorporates a theory-based pedagogical approach specificallydesigned for immigrant Hispanic adults on the US-Mexico border region. The article also describes the implementation of the curriculum aswell as the results of the evaluation, which was conducted using both quantitative and qualitative methods. Quantitative results indicate thatthe participants significantly improved their English proficiency (L2. Qualitative results suggest that participants were positively impactedby both the content and pedagogical approaches used by the curriculum. Their experience with the ESL class was positive in general. It canbe concluded that the curriculum achieved its objective. This approach could serve as a model for second language teaching for adults

aligns with the Ocean Literacy and Climate Literacy Frameworks, as well as multiple core ideas in the new National Academy of Sciences Framework for K-12 Science Education. In brief, the curriculum comprises 33 45-minute sessions organized into three thematic units that are each driven by an exploratory question: Unit 1 (11 sessions)-How do the ocean and atmosphere interact?; Unit 2 (8 sessions)-How does carbon flow through the ocean, land, and atmosphere?; and Unit 3 (12 sessions)-What are the causes and effects of climate change? The curriculum deliberately explores the ocean and climate as global systems, and challenges students to use scientific evidence to make explanations about climate change. The Ocean Sciences Sequence for Grades 6-8 is currently being classroom tested by teachers across the United States in a wide variety of classroom settings. Evaluation is also being undertaken to determine the efficacy of the sequence in addressing the curriculum's learning goals.

Esssential ethics--embedding ethics into an engineering curriculum.

Science.gov (United States)

Fleischmann, Shirley T

2004-04-01

Ethical decision-making is essential to professionalism in engineering. For that reason, ethics is a required topic in an ABET approved engineering curriculum and it must be a foundational strand that runs throughout the entire curriculum. In this paper the curriculum approach that is under development at the Padnos School of Engineering (PSE) at Grand Valley State University will be described. The design of this program draws heavily from the successful approach used at the service academies--in particular West Point and the United States Naval Academy. As is the case for the service academies, all students are introduced to the "Honor Concept" (which includes an Honor Code) as freshmen. As an element of professionalism the PSE program requires 1500 hours of co-op experience which is normally divided into three semesters of full-time work alternated with academic semesters during the last two years of the program. This offers the faculty an opportunity to teach ethics as a natural aspect of professionalism through the academic requirements for co-op. In addition to required elements throughout the program, the students are offered opportunities to participate in service projects which highlight responsible citizenship. These elements and other parts of the approach will be described.

In recent years, Music video data is increasing at an astonishing speed. Shot segmentation and keyframe extraction constitute a fundamental unit in organizing, indexing, retrieving video content. In this paper a unified framework is proposed to detect the shot boundaries and extract the keyframe of a shot. Music video is first segmented to shots by illumination-invariant chromaticity histogram in independent component (IC) analysis feature space .Then we presents a new metric, image complexity, to extract keyframe in a shot which is computed by ICs. Experimental results show the framework is effective and has a good performance.

Data driven design practices should be the basis for any effective educational product, particularly those used to support STEM learning and literacy. Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) is a five-year NASA-funded (NNX16AC53A) interdisciplinary and cross-institutional partnership to develop and disseminate STEM out-of-school time (OST) curricular and professional development units that integrate planetary science, technology, and engineering. The Center for Science Teaching and Learning at Northern Arizona University, the U.S. Geological Survey Astrogeology Science Center, and the Museum of Science Boston are partners in developing, piloting, and researching the impact of three out of school time units. Two units are for middle grades youth and one is for upper elementary aged youth. The presentation will highlight the data driven development process of the educational products used to provide support for educators teaching these curriculum units. This includes how data from the project needs assessment, curriculum pilot testing, and professional support product field tests are used in the design of products for out of school time educators. Based on data analysis, the project is developing and testing four tiers of professional support for OST educators. Tier 1 meets the immediate needs of OST educators to teach curriculum and include how-to videos and other direct support materials. Tier 2 provides additional content and pedagogical knowledge and includes short content videos designed to specifically address the content of the curriculum. Tier 3 elaborates on best practices in education and gives guidance on methods, for example, to develop cultural relevancy for underrepresented students. Tier 4 helps make connections to other NASA or educational products that support STEM learning in out of school settings. Examples of the tiers of support will be provided.

Objective Smokers with mental illness and addictive disorders account for nearly one in two cigarettes sold in the United States and are at high risk for smoking-related deaths and disability. Psychiatry residency programs provide a unique arena for disseminating tobacco treatment guidelines, influencing professional norms, and increasing access to tobacco cessation services among smokers with mental illness. The current study evaluated the Rx for Change in Psychiatry curriculum, developed for psychiatry residency programs and focused on identifying and treating tobacco dependence among individuals with mental illness. Methods The 4-hour curriculum emphasized evidence-based, patient-oriented cessation treatments relevant for all tobacco users, including those not yet ready to quit. The curriculum was informed by comprehensive literature review, consultation with an expert advisory group, faculty interviews, and a focus group with psychiatry residents. This study reports on evaluation of the curriculum in 2005–2006, using a quasi-experimental design, with 55 residents in three psychiatry residency training programs in Northern California. Results The curriculum was associated with improvements in psychiatry residents’ knowledge, attitudes, confidence, and counseling behaviors for treating tobacco use among their patients, with initial changes from pre- to posttraining sustained at 3-months’ follow-up. Residents’ self-reported changes in treating patients’ tobacco use were substantiated through systematic chart review. Conclusion The evidence-based Rx for Change in Psychiatry curriculum is offered as a model tobacco treatment curriculum that can be implemented in psychiatry residency training programs and disseminated widely, thereby effectively reaching a vulnerable and costly population of smokers.

Surgery interns' training has historically been weighted toward patient care, operative observation, and sleeping when possible. With more protected free time and less clinical time, real educational hours for trainees in 2013 are precious. We created a 20-session (3 hours each) simulation curriculum (with pre- and post-tests) and a 24/7 online audiovisual (AV) curriculum for surgery interns. Friday morning simulation sessions emphasize operative skills and judgment. AV clips (using operating room, whiteboard, and simulation center videos) take learners through 20 different general surgery operations with follow-up quizzes. We report our early experience with this novel setup. Thirty-two surgical interns (2012-2013) attended simulation sessions on 20 separate subjects (hernia, breast, hepatobiliary, endocrine, etc). Post-test scores improved (P 4.5; Likert scale, 1-5). The AV curriculum feedback is similar (mean, >4.3) and usage is available 24/7 preparing learners for both operating room and simulation sessions. Most simulation sessions utilize low-fidelity models to keep costs <$50 per session. Scores on our semiannual Surgical Olympics (mean score of 49.6 in July vs 82.9 in January; P < .05) improved significantly, suggesting that interns are improving their surgical skills and knowledge. Residents enjoy and learn from the step-by-step, in-house, AV curriculum and both appreciate and thrive on the 'hands-on' simulation sessions mimicking operations they see in real operating rooms. The cost of these programs is not prohibitive and the programs offer simulated repetitions for duty-hour-regulated trainees. Copyright © 2014 Mosby, Inc. All rights reserved.

Full Text Available Objective: To evaluate change in faculty’s knowledge and perceptions after an online video module on the Pharmacists’ Patient Care Process (PPCP. Innovation: An educational video module on the PPCP was developed and disseminated to full-time faculty members at Samford University, McWhorter School of Pharmacy. Voluntary and anonymous pre- and post-test assessments were evaluated and analyzed. Critical Analysis: Thirty faculty completed the pre-assessment, and 31 completed the post-assessment (73% and 75% response rates, respectively. A significant improvement in faculty perceptions was indicated by an increase in agreement with the majority (80% of questions on attitudes toward the PPCP on the post-test. Faculty’s knowledge of the introduction and assessment of PPCP within the school’s curriculum was significantly increased after viewing the video module. After viewing the module, more faculty were also able to correctly identify the majority of the PPCP components and their corresponding practice activities. Next Steps: A short video module was effective at improving faculty knowledge and perceptions of the PPCP. Development of a similar faculty development module is feasible for implementation in other Schools of Pharmacy.

2015-04-01

The Accreditation Council for Graduate Medical Education requires physicians training in pulmonary and critical care medicine to demonstrate competency in interpersonal communication. Studies have shown that residency training is often insufficient to prepare physicians to provide end-of-life care and facilitate patient and family decision-making. Poor communication in the intensive care unit (ICU) can adversely affect outcomes for critically ill patients and their family members. Despite this, communication training curricula in pulmonary and critical care medicine are largely absent in the published literature. We evaluated the effectiveness of a communication skills curriculum during the first year of a pulmonary and critical care medicine fellowship using a family meeting checklist to provide formative feedback to fellows during ICU rotations. We hypothesized that fellows would demonstrate increased competence and confidence in the behavioral skills necessary for facilitating family meetings. We evaluated a 12-month communication skills curriculum using a pre-post, quasiexperimental design. Subjects for this study included 11 first-year fellows who participated in the new curriculum (intervention group) and a historical control group of five fellows who had completed no formal communication curriculum. Performance of communication skills and self-confidence in family meetings were assessed for the intervention group before and after the curriculum. The control group was assessed once at the beginning of their second year of fellowship. Fellows in the intervention group demonstrated significantly improved communication skills as evaluated by two psychologists using the Family Meeting Behavioral Skills Checklist, with an increase in total observed skills from 51 to 65% (P ≤ 0.01; Cohen's D effect size [es], 1.13). Their performance was also rated significantly higher when compared with the historical control group, who demonstrated only 49% of observed skills

Qu, Zhiguo; Chen, Siyi; Ji, Sai

2017-11-01

As one of important multimedia forms in quantum network, quantum video attracts more and more attention of experts and scholars in the world. A secure quantum video steganography protocol with large payload based on the video strip encoding method called as MCQI (Multi-Channel Quantum Images) is proposed in this paper. The new protocol randomly embeds the secret information with the form of quantum video into quantum carrier video on the basis of unique features of video frames. It exploits to embed quantum video as secret information for covert communication. As a result, its capacity are greatly expanded compared with the previous quantum steganography achievements. Meanwhile, the new protocol also achieves good security and imperceptibility by virtue of the randomization of embedding positions and efficient use of redundant frames. Furthermore, the receiver enables to extract secret information from stego video without retaining the original carrier video, and restore the original quantum video as a follow. The simulation and experiment results prove that the algorithm not only has good imperceptibility, high security, but also has large payload.

To evaluate the pediatric residents' cardiopulmonary resuscitation (CPR) skills, and their improvements after recorded video feedbacks. Pediatric residents from a university hospital were enrolled. The authors surveyed the level of pediatric resuscitation skill confidence by a questionnaire. Eight psychomotor skills were evaluated individually, including airway, bag-mask ventilation, pulse check, prompt starting and technique of chest compression, high quality CPR, tracheal intubation, intraosseous, and defibrillation. The mock code skills were also evaluated as a team using a high-fidelity mannequin simulator. All the participants attended a concise Pediatric Advanced Life Support (PALS) lecture, and received video-recorded feedback for one hour. They were re-evaluated 6 wk later in the same manner. Thirty-eight residents were enrolled. All the participants had a moderate to high level of confidence in their CPR skills. Over 50 % of participants had passed psychomotor skills, except the bag-mask ventilation and intraosseous skills. There was poor correlation between their confidence and passing the psychomotor skills test. After course feedback, the percentage of high quality CPR skill in the second course test was significantly improved (46 % to 92 %, p = 0.008). The pediatric resuscitation course should still remain in the pediatric resident curriculum and should be re-evaluated frequently. Video-recorded feedback on the pitfalls during individual CPR skills and mock code case scenarios could improve short-term psychomotor CPR skills and lead to higher quality CPR performance.

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.

Noda, Hideki; Furuta, Tomofumi; Niimi, Michiharu; Kawaguchi, Eiji

2004-06-01

This paper presents a steganography method using lossy compressed video which provides a natural way to send a large amount of secret data. The proposed method is based on wavelet compression for video data and bit-plane complexity segmentation (BPCS) steganography. BPCS steganography makes use of bit-plane decomposition and the characteristics of the human vision system, where noise-like regions in bit-planes of a dummy image are replaced with secret data without deteriorating image quality. In wavelet-based video compression methods such as 3-D set partitioning in hierarchical trees (SPIHT) algorithm and Motion-JPEG2000, wavelet coefficients in discrete wavelet transformed video are quantized into a bit-plane structure and therefore BPCS steganography can be applied in the wavelet domain. 3-D SPIHT-BPCS steganography and Motion-JPEG2000-BPCS steganography are presented and tested, which are the integration of 3-D SPIHT video coding and BPCS steganography, and that of Motion-JPEG2000 and BPCS, respectively. Experimental results show that 3-D SPIHT-BPCS is superior to Motion-JPEG2000-BPCS with regard to embedding performance. In 3-D SPIHT-BPCS steganography, embedding rates of around 28% of the compressed video size are achieved for twelve bit representation of wavelet coefficients with no noticeable degradation in video quality.

Full Text Available Designing an effective and high performance network requires an accurate characterization and modeling of network traffic. The modeling of video frame sizes is normally applied in simulation studies and mathematical analysis and generating streams for testing and compliance purposes. Besides, video traffic assumed as a major source of multimedia traffic in future heterogeneous network. Therefore, the statistical distribution of video data can be used as the inputs for performance modeling of networks. The finding of this paper comprises the theoretical definition of distribution which seems to be relevant to the video trace in terms of its statistical properties and finds the best distribution using both the graphical method and the hypothesis test. The data set used in this article consists of layered video traces generating from Scalable Video Codec (SVC video compression technique of three different movies.

Curriculum theory in physical education

Science.gov (United States)

Jewett, Ann E.

1989-03-01

Primary current concerns of curriculum theorists in sport and physical education relate to clarification of value orientations underlying curricular decision-making, selection and statement of curriculum goals, identification and organization of programme content, and the process of curriculum change. Disciplinary mastery is the most traditional value orientation and that which is most frequently found in practice. Curriculum theorists have identified four other value orientations for study: social reconstruction, self-actualization, learning process, and ecological validity. Health-related fitness and the development of motor skills have long been the primary goals of physical education. In recent years, however, curriculum specialists have begun to assign higher priorities to goals of personal integration and challenge, of social development and multicultural understanding. There is general agreement that human movement activities constitute the subject-matter of the sport and physical education curriculum. Differences exist, however, as to how learning activities should be selected for particular programmes. The current trend in seeking better understanding of content is toward studying the operational curriculum with particular attention to the historical and social contexts. An important contemporary focus is the need to translate short-term results into lifestyle changes. The curriculum in sports and physical education should be viewed as a multitude of possibilities.

Violence in E-rated video games.

Thompson, K M; Haninger, K

2001-08-01

Children's exposure to violence, alcohol, tobacco and other substances, and sexual messages in the media are a source of public health concern; however, content in video games commonly played by children has not been quantified. To quantify and characterize the depiction of violence, alcohol, tobacco and other substances, and sex in video games rated E (for "Everyone"), analogous to the G rating of films, which suggests suitability for all audiences. We created a database of all existing E-rated video games available for rent or sale in the United States by April 1, 2001, to identify the distribution of games by genre and to characterize the distribution of content descriptors associated with these games. We played and assessed the content of a convenience sample of 55 E-rated video games released for major home video game consoles between 1985 and 2000. Game genre; duration of violence; number of fatalities; types of weapons used; whether injuring characters or destroying objects is rewarded or is required to advance in the game; depiction of alcohol, tobacco and other substances; and sexual content. Based on analysis of the 672 current E-rated video games played on home consoles, 77% were in sports, racing, or action genres and 57% did not receive any content descriptors. We found that 35 of the 55 games we played (64%) involved intentional violence for an average of 30.7% of game play (range, 1.5%-91.2%), and we noted significant differences in the amount of violence among game genres. Injuring characters was rewarded or required for advancement in 33 games (60%). The presence of any content descriptor for violence (n = 23 games) was significantly correlated with the presence of intentional violence in the game (at a 5% significance level based on a 2-sided Wilcoxon rank-sum test, t(53) = 2.59). Notably, 14 of 32 games (44%) that did not receive a content descriptor for violence contained acts of violence. Action and shooting games led to the largest numbers of

Automatic Story Segmentation for TV News Video Using Multiple Modalities

Directory of Open Access Journals (Sweden)

Émilie Dumont

2012-01-01

Full Text Available While video content is often stored in rather large files or broadcasted in continuous streams, users are often interested in retrieving only a particular passage on a topic of interest to them. It is, therefore, necessary to split video documents or streams into shorter segments corresponding to appropriate retrieval units. We propose here a method for the automatic segmentation of TV news videos into stories. A-multiple-descriptor based segmentation approach is proposed. The selected multimodal features are complementary and give good insights about story boundaries. Once extracted, these features are expanded with a local temporal context and combined by an early fusion process. The story boundaries are then predicted using machine learning techniques. We investigate the system by experiments conducted using TRECVID 2003 data and protocol of the story boundary detection task, and we show that the proposed approach outperforms the state-of-the-art methods while requiring a very small amount of manual annotation.

Wang, Chuan; Zhu, Jie; Guo, Yanwen; Wang, Wenping

2017-02-09

We present a video vectorization method that generates a video in vector representation from an input video in raster representation. A vector-based video representation offers the benefits of vector graphics, such as compactness and scalability. The vector video we generate is represented by a simplified tetrahedral control mesh over the spatial-temporal video volume, with color attributes defined at the mesh vertices. We present novel techniques for simplification and subdivision of a tetrahedral mesh to achieve high simplification ratio while preserving features and ensuring color fidelity. From an input raster video, our method is capable of generating a compact video in vector representation that allows a faithful reconstruction with low reconstruction errors.

Tian, Yan

2010-04-01

This study examines the content of and audience response to organ donation videos on YouTube, a Web 2.0 platform, with framing theory. Positive frames were identified in both video content and audience comments. Analysis revealed a reciprocity relationship between media frames and audience frames. Videos covered content categories such as kidney, liver, organ donation registration process, and youth. Videos were favorably rated. No significant differences were found between videos produced by organizations and individuals in the United States and those produced in other countries. The findings provide insight into how new communication technologies are shaping health communication in ways that differ from traditional media. The implications of Web 2.0, characterized by user-generated content and interactivity, for health communication and health campaign practice are discussed.

Video games can be played in many different contexts. This study examined associations between coplaying video games between siblings and levels of affection and conflict in the relationship. Participants were 508 adolescents (M age = 16.31 years of age, SD = 1.08) who completed questionnaires on video game use and sibling relationships. Participants were recruited from a large Northwestern city and a moderate city in the Mountain West of the United States. Video games played between siblings were coded by an independent sample to assess levels of physical aggression and prosocial behavior in each game. Playing video games with a sibling was associated with higher levels of sibling affection for both boys and girls, but higher levels of conflict for boys only. Playing a violent video game with a brother was associated with lower levels of conflict in the sibling relationship, whereas playing a prosocial video game was not related to any sibling outcome. The value of video games in sibling relationships will be discussed, with a focus on the type of game and the sex of the adolescent.

A substantial proportion of adverse intraoperative events are attributed to failures in nontechnical skills. To strengthen these skills and improve surgical safety, the Non-Technical Skills for Surgeons (NOTSS) taxonomy was developed as a common framework. The NOTSS taxonomy was adapted for low- and middle-income countries, where variable resources pose a significant challenge to safe surgery. The NOTSS for variable-resource contexts (VRC) curriculum was developed and implemented in Rwanda, with the aim of enhancing knowledge and attitudes about nontechnical skills and promoting surgical safety. The NOTSS-VRC curriculum was developed through a rigorous process of integrating contextually appropriate values. It was implemented as a 1-day training course for surgical and anesthesia postgraduate trainees. The curriculum comprises lectures, videos, and group discussions. A pretraining and posttraining questionnaire was administered to compare knowledge and attitudes regarding nontechnical skills, and their potential to improve surgical safety. The setting of this study was in the tertiary teaching hospital of Kigali, Rwanda. Participants were residents of the University of Kigali. A total of 55 residents participated from general surgery (31.4%), obstetrics (25.5%), anesthesia (17.6%), and other surgical specialties (25.5%). In a paired analysis, understanding of NOTSS improved significantly (55.6% precourse, 80.9% postcourse, pskills would improve patient outcomes. Nontechnical skills must be highlighted in surgical training in low- and middle-income countries. The NOTSS-VRC curriculum can be implemented without additional technology or significant financial cost. Its deliberate design for resource-constrained settings allows it to be used both as an educational course and a quality improvement strategy. Our research demonstrates it is feasible to improve knowledge and attitudes about NOTSS through a 1-day course, and represents a novel approach to improving global

Short Stories About The Ocean, an Art Integrated Project Into the Elementary Curriculum, Using Shadow Theatre and Video.

Guieu, M.; Scheurle, C.

2016-02-01

The holistic aspect of integrated learning reflects the way our world works: everything is interconnected. Integrated Learning connects students, teachers, academic content and the world. It creates bridges between disciplines, encourages invention, experimentation, and problem solving. In an art integrated lesson or project, the students learn in a creative way, exploring a given subject by working on an art project, individually or collectively, using an array of traditional techniques and technology tools. Short Stories about the Ocean is anchored in the 4th and 5th grade curriculum, the art technique is the shadow theatre. The students videotape the performances for documentation and sharing. After giving the students information about different types of human activities that have an impact on the ocean, and discussing them, the students form groups and choose a specific subject - for example over fishing or pipe spilling. They gather more information and create a story with a beginning, a development and an end. Prior to start the project, the teacher prepares a small shadow theatre made of simple material, with a template I provide. The teacher explains the basics in shadow theatre technique. The students work with paper and skewers to create the elements they need for their story. They find solutions to render proportions, movements, actions and timing. Each group rehearses and then presents to the class a two/three minutes performance. The students who watch give a positive critique. Each group takes the time to make changes if the story, the message or the elements need to be clearer. Each group performs in front of the class again. This collaborative work encourages decision making. The students have to define their idea and concept clearly, with enough details but not too many, so that their message is understood by the viewers. It is a challenge for the students to design the shapes they need for their story with minimal material and they must be

Cultural competence in the baccalaureate degree nursing curriculum

Science.gov (United States)

Silvestri, Angela

Health care providers are members of a helping profession and need to provide quality care to all members of society. As a result of current and projected demographic changes within the United States (U.S.), health care professionals are faced with the challenges of providing culturally competent care and fulfilling the role as the "helping profession." In the past 10 years, minority populations have increased in the U.S. For example, the African American population experienced an approximate 12.3% increase, and the Hispanic population increased by 43%. Just as it is necessary for health care professionals to respond to the increase in the geriatric population as a result of the Baby Boomer generation, it is crucial to address the needs of an increasingly culturally diverse population in the U.S. Preparing to care for a culturally diverse population begins during the teaching and learning process in the nursing curriculum. This study intended to identify the methods in which nursing programs are integrating cultural concepts in their plan of study. Josepha Campinha-Bacote's model titled "The Process of Cultural Competence in the Delivery of Health Care Services" was used as the theoretical framework to guide this study. Campinha-Bacote has studied transcultural nursing and has added to the current body of nursing knowledge with regard to incorporating cultural concepts in the nursing curriculum. This model requires health care professionals to see themselves as becoming culturally competent rather than being culturally competent and involves the integration of cultural awareness, cultural skill, cultural knowledge, cultural encounters, and cultural desire. An electronic survey was sent using Survey Monkey to 298 schools in the Northeast and Southern regions of the United States. The survey was sent on January 19, 2012 and remained open for 20 days. Once the survey closed, statistical analyses were conducted using frequencies and cross-tabluations, and the findings

Aspects of radiation effects due to visual display units at work

International Nuclear Information System (INIS)

Vana, N.

1988-01-01

The introduction and acceptance of video display units at work have led to a huge flood of information, rumours, and half-truths about those units. As the population became increasingly sensitized to 'radioactive radiation', there was, and in part still is, a tendency to consider particularly effects of unclear origin, first of all ionizing radiation and later on also non-ionizing radiation, as the main threat from video display units at work. Such important issuses as ergonomics, stress load, visual stress load, and social hygiene are often effaced by the question for 'the radiation load from visual display units'. The paper is an attempt to deal with aspects of radiation effects of visual display units at work. The discussion also extends to hazards, respectively the 'radiation environment', at the site of the visual display unit. (orig./DG) [de

Video Games as a Multifaceted Medium: A Review of Quantitative Social Science Research on Video Games and a Typology of Video Game Research Approaches

Directory of Open Access Journals (Sweden)

James D. Ivory

2013-01-01

Full Text Available Although there is a vast and useful body of quantitative social science research dealing with the social role and impact of video games, it is difficult to compare studies dealing with various dimensions of video games because they are informed by different perspectives and assumptions, employ different methodologies, and address different problems. Studies focusing on different social dimensions of video games can produce varied findings about games’ social function that are often difficult to reconcile— or even contradictory. Research is also often categorized by topic area, rendering a comprehensive view of video games’ social role across topic areas difficult. This interpretive review presents a novel typology of four identified approaches that categorize much of the quantitative social science video game research conducted to date: “video games as stimulus,” “video games as avocation,” “video games as skill,” and “video games as social environment.” This typology is useful because it provides an organizational structure within which the large and growing number of studies on video games can be categorized, guiding comparisons between studies on different research topics and aiding a more comprehensive understanding of video games’ social role. Categorizing the different approaches to video game research provides a useful heuristic for those critiquing and expanding that research, as well as an understandable entry point for scholars new to video game research. Further, and perhaps more importantly, the typology indicates when topics should be explored using different approaches than usual to shed new light on the topic areas. Lastly, the typology exposes the conceptual disconnects between the different approaches to video game research, allowing researchers to consider new ways to bridge gaps between the different approaches’ strengths and limitations with novel methods.

High-level radioactive waste curriculum usage, evaluation, and customer focus

International Nuclear Information System (INIS)

King, G.P.

1994-01-01

In August 1992, the U.S. Department of Energy's Office of Civilian Radioactive Waste Management (OCRWM) issued for educator use, a secondary school resource curriculum entitled open-quotes Science, Society, and America's Nuclear Wasteclose quotes. This resource curriculum was developed in response to years and thousands of teacher, student, and general public requests for facts about nuclear waste -- specifically, what the United States was doing and why. The curriculum materials when issued were the result of six years of development and testing by science and social studies teachers as well as multi-state field-testing and international critique. The curriculum is provided only to educators who specifically request it; and in the first one-and-a-half years following its availability more than 500,000 curriculum documents have been requested. Of all the requests for information received by OCRWM for any information or materials, most requests received are from educators or students. So one might consider educators and students to be open-quotes customerclose quotes, that is, as the business world might define customers: anyone expecting a product or a service from us. To determine usefulness and content for future editions of open-quotes Science, Society, and America's Nuclear Wasteclose quotes, the Office of Civilian Radioactive Waste Management has undertaken a usage evaluation to ensure that it focuses on the needs of the open-quotes customerclose quotes; that is, those who need and request it. This paper presents preliminary findings based on a formal evaluation provided to and requested from educators, unsolicited comments received from educator requesters of the material, and comments from others

Anatomy as the Backbone of an Integrated First Year Medical Curriculum: Design and Implementation

Science.gov (United States)

Klement, Brenda J.; Paulsen, Douglas F.; Wineski, Lawrence E

2011-01-01

Morehouse School of Medicine chose to restructure its first year medical curriculum in 2005. The anatomy faculty had prior experience in integrating courses, stemming from the successful integration of individual anatomical sciences courses into a single course called Human Morphology. The integration process was expanded to include the other first year basic science courses (Biochemistry, Physiology, and Neurobiology) as we progressed toward an integrated curriculum. A team, consisting of the course directors, a curriculum coordinator and the Associate Dean for Educational and Faculty Affairs, was assembled to build the new curriculum. For the initial phase, the original course titles were retained but the lecture order was reorganized around the Human Morphology topic sequence. The material from all four courses was organized into four sequential units. Other curricular changes included placing laboratories and lectures more consistently in the daily routine, reducing lecture time from 120 to 90 minute blocks, eliminating unnecessary duplication of content, and increasing the amount of independent study time. Examinations were constructed to include questions from all courses on a single test, reducing the number of examination days in each block from three to one. The entire restructuring process took two years to complete, and the revised curriculum was implemented for the students entering in 2007. The outcomes of the restructured curriculum include a reduction in the number of contact hours by 28%, higher or equivalent subject examination average scores, enhanced student satisfaction, and a first year curriculum team better prepared to move forward with future integration.

Background Chief residents receive minimal formal training in preparation for their administrative responsibilities. There is a lack of professional development programs specifically designed for chief residents. Objective In 2015, Academic Life in Emergency Medicine designed and implemented an annual, year-long, training program and virtual community of practice for chief residents in emergency medicine (EM). This study describes the curriculum design process and reports measures of learner engagement during the first two cycles of the curriculum. Methods Kern's Six-Step Approach for curriculum development informed key decisions in the design and implementation of the Chief Resident Incubator. The resultant curriculum was created using constructivist social learning theory, with specific objectives that emphasized the needs for a virtual community of practice, longitudinal content delivery, mentorship for participants, and the facilitation of multicenter digital scholarship. The 12-month curriculum included 11 key administrative or professional development domains, delivered using a combination of digital communications platforms. Primary outcomes measures included markers of learner engagement with the online curriculum, recognized as modified Kirkpatrick Level One outcomes for digital learning. Results An average of 206 chief residents annually enrolled in the first two years of the curriculum, with an overall participation by 33% (75/227) of the allopathic EM residency programs in the United States (U.S.). There was a high level of learner engagement, with an average 13,414 messages posted per year. There were also 42 small group teaching sessions held online, which included 39 faculty and 149 chief residents. The monthly e-newsletter had a 50.7% open rate. Digital scholarship totaled 23 online publications in two years, with 67 chief resident co-authors and 21 faculty co-authors. Conclusions The Chief Resident Incubator is a virtual community of practice that

The same teacher, the same curriculum materials, different schools: What is the enacted curriculum?

Science.gov (United States)

Eisenmann, Tammy

This research examines how the same teacher implements the same curriculum material in two different schools. The aim of the study is to examine how the enacted algebra curriculum may change when the same teacher enacts the same written curriculum materials in different classes. This research comprises two case studies. Each case examines one teacher who taught the beginning of the mathematical topic "equivalent algebraic expressions", to two 7th grade classes from different schools. The same textbook was used in all four classes. The data collected includes: 1. Observations: 25930 lessons throughout the school year in each of the participating classes; Other mathematics classes in each of the schools; Other non9mathematics classes in the participating classes. A total of 130 lessons were observed. The observations included continuous observations of the teaching of "equivalent algebraic expressions" (15919 lessons) in each class. These observations are the main data source of this research; 2. Interviews with the teachers; 3. Informal conversations; and 4. Field notes. The data was analyzed both through quantitative and qualitative analysis. The research focuses on the following two aspects of the enacted curriculum: implementation of the recommendation that appeared in the curriculum materials and the types of algebraic activity that the students were exposed to during the teaching of the mathematical topic. Kieran's framework (Kieran, 1996, 2004), which distinguishes between three types of algebraic activities 9 generational, transformational and global/meta9level 9 was employed for the examination of the algebraic activities. Comparisons were made for two aspects of the research: between the enacted curriculum in each of the classes and the curriculum materials; and between each of the classes taught by same teacher. It was found that in case study 1, that examined teacher Sara and schools Carmel and Tavor -- most of the recommendations for instruction that

2012-01-01

Full Text Available With the development of heterogeneous networks and video coding standards, multiresolution video applications over networks become important. It is critical to ensure the service quality of the network for time-sensitive video services. Worldwide Interoperability for Microwave Access (WIMAX is a good candidate for delivering video signals because through WIMAX the delivery quality based on the quality-of-service (QoS setting can be guaranteed. The selection of suitable QoS parameters is, however, not trivial for service users. Instead, what a video service user really concerns with is the video quality of presentation (QoP which includes the video resolution, the fidelity, and the frame rate. In this paper, we present a quality control mechanism in multiresolution video coding structures over WIMAX networks and also investigate the relationship between QoP and QoS in end-to-end connections. Consequently, the video presentation quality can be simply mapped to the network requirements by a mapping table, and then the end-to-end QoS is achieved. We performed experiments with multiresolution MPEG coding over WIMAX networks. In addition to the QoP parameters, the video characteristics, such as, the picture activity and the video mobility, also affect the QoS significantly.

Full Text Available Audience: The eConference is an interactive video conference grand rounds innovation to augment the didactic curriculum provided for medical students, interns, residents, fellows, and attending physicians. Introduction: Formal education during emergency medicine (EM training has historically emphasized aspects of humanism and constructivism; the former through self-directed reading in books and journals, the latter through the content and discussion during resident didactics.1 However, some studies suggest that the current generation of EM learners are increasingly using digital and internet technologies to connect with online peer networks, a phenomenon known as connectivism.2 As such, contemporary EM learners are increasingly utilizing social media and Free Open Access Medical Education (FOAM to supplement traditional learning resources. The eConference was developed to be an interactive, virtual grand rounds that marries the merits of constructivism with connectivism; a new format of EM didactics that goes beyond the “typical lecture” model to incorporate the changing landscape in technology and medical education by combining classroom teaching at multiple institutions alongside digital learning tools. This manuscript outlines how to plan and execute a joint video conference with another institution. Objectives: Our objectives were to create and implement a novel virtual conference format through the integration of social media tools which allows for interdisciplinary and multi-site participation to enhance EM resident education. We wish to outline the steps required to reproduce this innovative session and share lessons learned. Conclusion: We designed and executed a multi-centered, novel form of virtual conference into the EM residency curriculum at two participating institutions. The virtual conference took place during a routine conference day for both programs, an hour in duration. The format utilized a hybrid of live and virtual

Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) is a five-year NASA-funded (NNX16AC53A) interdisciplinary and cross-institutional partnership to develop and disseminate STEM out-of-school time (OST) curricular and professional development units that integrate planetary science, technology, and engineering. The Center for Science Teaching and Learning (CSTL) and Department of Physics and Astronomy (P&A) at Northern Arizona University, the U.S. Geological Survey Astrogeology Science Center (USGS ASC), and the Museum of Science Boston (MoS) are partners in developing, piloting, and researching the impact of three out-of-school time units. Planetary scientists at USGS ASC and P&A have developed two units for middle grades youth and one for upper elementary aged youth. The two middle school units focus on greywater recycling and remote sensing of planetary surfaces while the elementary unit centers on exploring space hazards. All units are designed for small teams of ~4 youth to work together to investigate materials, engineer tools to assist in the explorations, and utilize what they have learned to solve a problem. Youth participate in a final share-out with adults and other youth of what they learned and their solution to the problem. Curriculum pilot testing of the two middle school units has begun with out-of-school time educators. A needs assessment has been conducted nationwide among educators and evaluation of the curriculum units is being conducted by CSTL during the pilot testing. Based on data analysis, the project is developing and testing four tiers of professional support for OST educators. Tier 1 meets the immediate needs of OST educators to teach curriculum and include how-to videos and other direct support materials. Tier 2 provides additional content and pedagogical knowledge and includes short content videos designed to specifically address the content of the curriculum. Tier 3 elaborates on best practices

Educational Borrowing and Mathematics Curriculum: Realistic Mathematics Education in the Dutch and Indonesian Primary Curriculum

Directory of Open Access Journals (Sweden)

Shintia Revina

2018-02-01

Full Text Available Since the late 1990s, Indonesian mathematics educators have considered Realistic Mathematics Education (RME, the Dutch approach to mathematics instruction, to be the basis for educational reform. In the National curriculum development, RME has, therefore, been reviewed as among the theoretical references to the curriculum goals and content. In the present study, an analysis of the consistency between RME and the curriculum descriptors and contents in Indonesia is presented. This is supplemented with some comparisons to that in the Netherlands. Findings in this study revealed that while most of RME principles are reflected in the Indonesian curriculum, the descriptions were often very general and less explicit compared to the Dutch curriculum. They were also limited by the content-based approach as well as by the centralized decision making process of the contents to be taught which have been pre-determined at the national level. This study suggests future research to see how the curriculum may influence teachers’ enactment of RME at classroom level.

State-of-the-Art Pediatric Hypnosis Training: Remodeling Curriculum and Refining Faculty Development.

Science.gov (United States)

Kohen, Daniel P; Kaiser, Pamela; Olness, Karen

2017-01-01

Training in pediatric hypnosis has been part of clinical hypnosis education in the United States since 1976. Workshops expanded over time and are now taught by highly experienced pediatric clinicians across the globe. In 1987, a small vanguard of North American faculty, academic pediatricians, and pediatric psychologists taught a 3-day pediatric hypnosis workshop at the national meeting of the Society for Developmental and Behavioral Pediatrics (SDBP). This model of annual tri-level concurrent workshops (introductory, intermediate, and advanced) was sponsored by the SDBP for 24 years. In 2009, the National Pediatric Hypnosis Training Institute (NPHTI) assembled, and in 2010, offered its first annual workshops. This article documents this history of pediatric hypnosis education and describes NPHTI's remodeling and ongoing refinement toward a state-of-the-art curriculum with innovative methodology based upon (1) current research about adult experiential and small group learning; (2) design principles for presentations that maximize adult learning and memory; and (3) evaluations by participants and faculty. These underpinnings-including clinical training videos, individualized learning choices, emphasis on personalized, goal-oriented sessions, and advances in faculty selection, and ongoing development-are applicable to adult training models. Integration of developmental and self-regulation strategies may be more unique to pediatric hypnosis skills training programs. The conclusion proposes expansion of pediatric hypnosis education and elimination of related barriers toward goals that all children learn self-hypnosis (SH) for mind-body health.

Reflections on academic video

Directory of Open Access Journals (Sweden)

Thommy Eriksson

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.

Perspective: clinical communication education in the United Kingdom: some fresh insights.

Science.gov (United States)

Brown, Jo

2012-08-01

Clinical communication education is now part of the core curriculum of every medical school in the United Kingdom and the United States. It has emerged over 30 years because of various societal, political, and policy drivers and is supported by an impressive evidence base.For a variety of reasons, however, clinical communication has become separated from other parts of medical education and tends to be positioned in the early years of the curriculum, when students have limited experience of being in the clinical workplace and working with patients. The teachers of clinical communication, whether medical-school-based or clinically based, may not share learning goals for the subject and this may, therefore, provide a disintegrated learning experience for students.Clinical communication teachers need to inject fresh thinking into the teaching and learning of the subject to unite it with clinical practice in the authentic clinical workplace. Engaging with theories of workplace learning, which aim to overcome the theory/practice gap in vocational education, may be the way forward. The author suggests various ways that this might be achieved-for example, by situating clinical communication education throughout the whole undergraduate curriculum, by integrating the topic of clinical communication with other areas of medical education, by developing coteaching and curriculum design partnerships between medical school and clinical workplace, and by developing a greater range of postgraduate education that offers opportunities for professional development in clinical communication for qualified doctors that is complementary with what is taught in undergraduate education.

Carter, R.J.

1997-04-01

The primary purpose of the "modification and validation of an automotive data processing unit (DPU), compressed video system, and communications equipment" cooperative research and development agreement (CRADA) was to modify and validate both hardware and software, developed by Scientific Atlanta, Incorporated (S-A) for defense applications (e.g., rotary-wing airplanes), for the commercial sector surface transportation domain (i.e., automobiles and trucks). S-A also furnished a state-of-the-art compressed video digital storage and retrieval system (CVDSRS), and off-the-shelf data storage and transmission equipment to support the data acquisition system for crash avoidance research (DASCAR) project conducted by Oak Ridge National Laboratory (ORNL). In turn, S-A received access to hardware and technology related to DASCAR. DASCAR was subsequently removed completely and installation was repeated a number of times to gain an accurate idea of complete installation, operation, and removal of DASCAR. Upon satisfactory completion of the DASCAR construction and preliminary shakedown, ORNL provided NHTSA with an operational demonstration of DASCAR at their East Liberty, OH test facility. The demonstration included an on-the-road demonstration of the entire data acquisition system using NHTSA'S test track. In addition, the demonstration also consisted of a briefing, containing the following: ORNL generated a plan for validating the prototype data acquisition system with regard to: removal of DASCAR from an existing vehicle, and installation and calibration in other vehicles; reliability of the sensors and systems; data collection and transmission process (data integrity); impact on the drivability of the vehicle and obtrusiveness of the system to the driver; data analysis procedures; conspicuousness of the vehicle to other drivers; and DASCAR installation and removal training and documentation. In order to identify any operational problems not captured by the systems

The Development of Mathematical Knowledge for Teaching for Quantitative Reasoning Using Video-Based Instruction

Science.gov (United States)

Walters, Charles David

Quantitative reasoning (P. W. Thompson, 1990, 1994) is a powerful mathematical tool that enables students to engage in rich problem solving across the curriculum. One way to support students' quantitative reasoning is to develop prospective secondary teachers' (PSTs) mathematical knowledge for teaching (MKT; Ball, Thames, & Phelps, 2008) related to quantitative reasoning. However, this may prove challenging, as prior to entering the classroom, PSTs often have few opportunities to develop MKT by examining and reflecting on students' thinking. Videos offer one avenue through which such opportunities are possible. In this study, I report on the design of a mini-course for PSTs that featured a series of videos created as part of a proof-of-concept NSF-funded project. These MathTalk videos highlight the ways in which the quantitative reasoning of two high school students developed over time. Using a mixed approach to grounded theory, I analyzed pre- and postinterviews using an extant coding scheme based on the Silverman and Thompson (2008) framework for the development of MKT. This analysis revealed a shift in participants' affect as well as three distinct shifts in their MKT around quantitative reasoning with distances, including shifts in: (a) quantitative reasoning; (b) point of view (decentering); and (c) orientation toward problem solving. Using the four-part focusing framework (Lobato, Hohensee, & Rhodehamel, 2013), I analyzed classroom data to account for how participants' noticing was linked with the shifts in MKT. Notably, their increased noticing of aspects of MKT around quantitative reasoning with distances, which features prominently in the MathTalk videos, seemed to contribute to the emergence of the shifts in MKT. Results from this study link elements of the learning environment to the development of specific facets of MKT around quantitative reasoning with distances. These connections suggest that vicarious experiences with two students' quantitative

Video Toroid Cavity Imager

A video toroid cavity imager for in situ measurement of electrochemical properties of an electrolytic material sample includes a cylindrical toroid cavity resonator containing the sample and employs NMR and video imaging for providing high-resolution spectral and visual information of molecular characteristics of the sample on a real-time basis. A large magnetic field is applied to the sample under controlled temperature and pressure conditions to simultaneously provide NMR spectroscopy and video imaging capabilities for investigating electrochemical transformations of materials or the evolution of long-range molecular aggregation during cooling of hydrocarbon melts. The video toroid cavity imager includes a miniature commercial video camera with an adjustable lens, a modified compression coin cell imager with a fiat circular principal detector element, and a sample mounted on a transparent circular glass disk, and provides NMR information as well as a video image of a sample, such as a polymer film, with micrometer resolution.

A Fuzzy Logic-Based Video Subtitle and Caption Coloring System

Directory of Open Access Journals (Sweden)

Mohsen Davoudi

2012-01-01

Full Text Available An approach has been proposed for automatic adaptive subtitle coloring using fuzzy logic-based algorithm. This system changes the color of the video subtitle/caption to “pleasant” color according to color harmony and the visual perception of the image background colors. In the fuzzy analyzer unit, using RGB histograms of background image, the R, G, and B values for the color of the subtitle/caption are computed using fixed fuzzy IF-THEN rules fully driven from the color harmony theories to satisfy complementary color and subtitle-background color harmony conditions. A real-time hardware structure has been proposed for implementation of the front-end processing unit as well as the fuzzy analyzer unit.

Ethics Education in Midwifery Education Programs in the United States.

2016-09-01

Familiarity with ethical concepts is a required competency for new graduates and a component of accreditation for midwifery education programs in the United States. While midwifery educators have acknowledged the importance of ethics education in midwifery programs, little is known about current methods, format, or evaluation of ethics education. A Web-based survey was developed for program directors of accredited midwifery education programs in the United States. Clock hours, formats, venues, content topics, barriers, and evaluation methods were evaluated by descriptive analysis. Fifty-one percent of programs completed the online survey (25/49). Of these, only 7 (28%) offer ethics as a stand-alone class, although all responding programs integrate some ethics education into other core classes. Programs show variation in format, venue, resources, and clock hours dedicated to ethics education. The most frequent barrier to ethics education is an already crowded curriculum (60%), although 32% of programs denied any barriers at all. The majority of programs include the ethical concepts of informed consent, shared decision making, and effective communication in curriculum content. This survey found that there is considerable variation in ethics education in terms of content, format, and evaluation among accredited midwifery education programs in the United States. Midwifery educators have an opportunity to explore the ethical dilemmas unique to maternity care from a midwifery perspective. There is also the opportunity to create a comprehensive and dynamic midwifery ethics curriculum, which incorporates both stand-alone ethics courses and ethics concepts that are woven throughout the core midwifery curriculum. © 2016 by the American College of Nurse-Midwives.

The significant global variations in surgical oncology training paradigms can have a detrimental effect on tackling the rising global cancer burden. While some variations in training are essential to account for the differences in types of cancer and biology, the fundamental principles of providing care to a cancer patient remain the same. The development of a global curriculum in surgical oncology with incorporated essential standards could be very useful in building an adequately trained surgical oncology workforce, which in turn could help in tackling the rising global cancer burden. The leaders of the Society of Surgical Oncology and European Society of Surgical Oncology convened a global curriculum committee to develop a global curriculum in surgical oncology. A global curriculum in surgical oncology was developed to incorporate the required domains considered to be essential in training a surgical oncologist. The curriculum was constructed in a modular fashion to permit flexibility to suit the needs of the different regions of the world. Similarly, recognizing the various sociocultural, financial and cultural influences across the world, the proposed curriculum is aspirational and not mandatory in intent. A global curriculum was developed which may be considered as a foundational scaffolding for training surgical oncologists worldwide. It is envisioned that this initial global curriculum will provide a flexible and modular scaffolding that can be tailored by individual countries or regions to train surgical oncologists in a way that is appropriate for practice in their local environment.

Deep video deblurring

KAUST Repository

Su, Shuochen

2016-11-25

Motion blur from camera shake is a major problem in videos captured by hand-held devices. Unlike single-image deblurring, video-based approaches can take advantage of the abundant information that exists across neighboring frames. As a result the best performing methods rely on aligning nearby frames. However, aligning images is a computationally expensive and fragile procedure, and methods that aggregate information must therefore be able to identify which regions have been accurately aligned and which have not, a task which requires high level scene understanding. In this work, we introduce a deep learning solution to video deblurring, where a CNN is trained end-to-end to learn how to accumulate information across frames. To train this network, we collected a dataset of real videos recorded with a high framerate camera, which we use to generate synthetic motion blur for supervision. We show that the features learned from this dataset extend to deblurring motion blur that arises due to camera shake in a wide range of videos, and compare the quality of results to a number of other baselines.

Toward enhancing the distributed video coder under a multiview video codec framework

Science.gov (United States)

Lee, Shih-Chieh; Chen, Jiann-Jone; Tsai, Yao-Hong; Chen, Chin-Hua

2016-11-01

The advance of video coding technology enables multiview video (MVV) or three-dimensional television (3-D TV) display for users with or without glasses. For mobile devices or wireless applications, a distributed video coder (DVC) can be utilized to shift the encoder complexity to decoder under the MVV coding framework, denoted as multiview distributed video coding (MDVC). We proposed to exploit both inter- and intraview video correlations to enhance side information (SI) and improve the MDVC performance: (1) based on the multiview motion estimation (MVME) framework, a categorized block matching prediction with fidelity weights (COMPETE) was proposed to yield a high quality SI frame for better DVC reconstructed images. (2) The block transform coefficient properties, i.e., DCs and ACs, were exploited to design the priority rate control for the turbo code, such that the DVC decoding can be carried out with fewest parity bits. In comparison, the proposed COMPETE method demonstrated lower time complexity, while presenting better reconstructed video quality. Simulations show that the proposed COMPETE can reduce the time complexity of MVME to 1.29 to 2.56 times smaller, as compared to previous hybrid MVME methods, while the image peak signal to noise ratios (PSNRs) of a decoded video can be improved 0.2 to 3.5 dB, as compared to H.264/AVC intracoding.

Galloway, L. M.; Roberts, K.; Leake, D. W.; Stodden, R. S.; Crabbe, V.

2005-12-01

The marvels of modern science often fail to engage indigenous students, as the content and instructional style are usually rooted in the Western experience. This 3 year project, funded by the US Dept. of Education for the Education of Native Hawaiians, offers a curriculum that teaches science through (rather than just about) Native Hawaiian culture. The curriculum focuses on the interdependence of natural resources in our ahupuaa, or watersheds, and helps students strengthen their sense of place and self to malama i ka aina, to care for the land. Further, the curriculum is designed to: engage students in scientific study with relevant, interesting content and activities; improve student achievement of state department of education standards; increase student knowledge and skills in science, math and language arts; respond to the learning needs of Native Hawaiian and/or at-risk students. The project will be presented by a curriculum writer who created and adapted more than a year's worth of materials by teaming with kupuna (respected elders), local cultural experts and role models, educators (new, veteran, Hawaiian, non-Hawaiian, mainland, general and special education teachers), and professionals at the Center on Disability Studies at the University of Hawaii and ALU LIKE, Inc, a non-profit organization to assist Native Hawaiians. The materials created thus far are available for viewing at: www.scihi.hawaii.edu The curriculum, designed for grades 8-11 science classes, can be used to teach a year-long course, a unit, or single lesson related to astronomy, biology, botany, chemistry, geology, oceanography, physical and environmental sciences. This project is in its final year of field testing, polishing and dissemination, and therefore this session will encourage idea sharing, as does our copyright free Web site.

Camera network video summarization

Science.gov (United States)

Panda, Rameswar; Roy-Chowdhury, Amit K.

2017-05-01

Networks of vision sensors are deployed in many settings, ranging from security needs to disaster response to environmental monitoring. Many of these setups have hundreds of cameras and tens of thousands of hours of video. The difficulty of analyzing such a massive volume of video data is apparent whenever there is an incident that requires foraging through vast video archives to identify events of interest. As a result, video summarization, that automatically extract a brief yet informative summary of these videos, has attracted intense attention in the recent years. Much progress has been made in developing a variety of ways to summarize a single video in form of a key sequence or video skim. However, generating a summary from a set of videos captured in a multi-camera network still remains as a novel and largely under-addressed problem. In this paper, with the aim of summarizing videos in a camera network, we introduce a novel representative selection approach via joint embedding and capped l21-norm minimization. The objective function is two-fold. The first is to capture the structural relationships of data points in a camera network via an embedding, which helps in characterizing the outliers and also in extracting a diverse set of representatives. The second is to use a capped l21-norm to model the sparsity and to suppress the influence of data outliers in representative selection. We propose to jointly optimize both of the objectives, such that embedding can not only characterize the structure, but also indicate the requirements of sparse representative selection. Extensive experiments on standard multi-camera datasets well demonstrate the efficacy of our method over state-of-the-art methods.

Video image processor on the Spacelab 2 Solar Optical Universal Polarimeter /SL2 SOUP/

Science.gov (United States)

Lindgren, R. W.; Tarbell, T. D.

1981-01-01

The SOUP instrument is designed to obtain diffraction-limited digital images of the sun with high photometric accuracy. The Video Processor originated from the requirement to provide onboard real-time image processing, both to reduce the telemetry rate and to provide meaningful video displays of scientific data to the payload crew. This original concept has evolved into a versatile digital processing system with a multitude of other uses in the SOUP program. The central element in the Video Processor design is a 16-bit central processing unit based on 2900 family bipolar bit-slice devices. All arithmetic, logical and I/O operations are under control of microprograms, stored in programmable read-only memory and initiated by commands from the LSI-11. Several functions of the Video Processor are described, including interface to the High Rate Multiplexer downlink, cosmetic and scientific data processing, scan conversion for crew displays, focus and exposure testing, and use as ground support equipment.

In the present study we investigated the effect of television watching and the use of activity-promoting video games on energy expenditure in obese and lean children. Energy expenditure and physical activity were measured while participants were watching television, playing a video game on a traditional sedentary video game console, and while playing the same video game on an activity-promoting video game console. Energy expenditure was significantly greater than television watching and playing video games on a sedentary video game console when children played the video game on the activity-promoting console. When examining movement with accelerometry, children moved significantly more when playing the video game on the Nintendo Wii console. Activity-promoting video games have shown to increase movement, and be an important tool to raise energy expenditure by 50% when compared to sedentary activities of daily living.

The Next Generation Advanced Video Guidance Sensor (NGAVGS) is the latest in a line of sensors that have flown four times in the last 10 years. The NGAVGS has been under development for the last two years as a long-range proximity operations and docking sensor for use in an Automated Rendezvous and Docking (AR&D) system. The first autonomous rendezvous and docking in the history of the U.S. Space Program was successfully accomplished by Orbital Express, using the Advanced Video Guidance Sensor (AVGS) as the primary docking sensor. That flight proved that the United States now has a mature and flight proven sensor technology for supporting Crew Exploration Vehicles (CEV) and Commercial Orbital Transport Systems (COTS) Automated Rendezvous and Docking (AR&D). NASA video sensors have worked well in the past: the AVGS used on the Demonstration of Autonomous Rendezvous Technology (DART) mission operated successfully in "spot mode" out to 2 km, and the first generation rendezvous and docking sensor, the Video Guidance Sensor (VGS), was developed and successfully flown on Space Shuttle flights in 1997 and 1998. This paper presents the flight heritage and results of the sensor technology, some hardware trades for the current sensor, and discusses the needs of future vehicles that may rendezvous and dock with the International Space Station (ISS) and other Constellation vehicles. It also discusses approaches for upgrading AVGS to address parts obsolescence, and concepts for minimizing the sensor footprint, weight, and power requirements. In addition, the testing of the various NGAVGS development units will be discussed along with the use of the NGAVGS as a proximity operations and docking sensor.

This paper presents a novel approach to fast motion detection in H.264/MPEG-4 advanced video coding (AVC) compressed video streams for IP video surveillance systems. The goal is to develop algorithms which may be useful in a real-life industrial perspective by facilitating the processing of large...... on motion vectors embedded in the video stream without requiring a full decoding and reconstruction of video frames. To improve the robustness to noise, a confidence measure based on temporal and spatial clues is introduced to increase the probability of correct detection. The algorithm was tested on indoor...
