Research on Intelligent Strategies and Challenges of Intangible Cultural Heritage Inheritance in the Age of Digital Economy

Abstract The intelligent construction and protection of intangible cultural heritage resources is an innovative approach to inheritance and development that fosters the survival of these resources, as well as an effective arrangement for the joint development of high-quality cultural and intangible cultural heritage resources. In this paper, we design a resource library based on 3D reconstruction, which we then implement online to create an intangible cultural heritage landscape. In addition, based on the characteristics of volume video technology, the innovative experience of building intangible cultural heritage is applied. Through an in-depth inquiry, this paper presents strategies for promoting body diversity, creating engaging communication content, disseminating the technology in detail, and developing a communication strategy for the intangible cultural heritage concept.

Forecasting the broadcast volume of cultural communication assisted by short video technology and analyzing the influencing factors

Selecting the user comment information of short videos with top 2 likes in the top 50 topics about public cultural services in Shake App as the research object, and facilitating video platforms to identify the high and low quality of the videos and make reasonable promotion arrangements by predicting the short-term playback volume of pop-up videos and analyzing the influencing factors, which is conducive to improving the platform’s pop-up video services and economic benefits. The data related to B station videos are captured, and feature selection and different algorithms are combined to construct random forest model, XG Boost model and LSTM model to predict the playback volume of the pop-up videos, and compare and analyze the effects of different feature combinations on the experimental results. The results show that the prediction accuracy of the random forest model is higher than that of the XG Boost model and the LSTM model, and the features of the pop-up video itself have the greatest influence on the playback volume, while the features of the video markup text have a smaller degree of influence on the playback volume.

The effect of evaluation and feedback in 360-degree video-based VR environments on language learning outcomes

Recently, 360-degree video technology (360VT) received considerable attention in the field of computer-assisted language learning as it creates authentic and immersive virtual reality environments to assist the language learning process. However, not many studies focused on applications of 360VT to assist the evaluation of learner’ performance and providing them with relevant feedback. Therefore, the present study was set to shed light on this aspect. We carried out an experiment to explore the effects of evaluation and feedback in two different video learning environments, i.e. a traditional video technology-based (TVT) and 360VT-based, on learning outcomes. In the context of the present study, evaluation referred to evaluating the content of videos created by students, and feedback referred to providing students with relevant feedback for further improvement of their videos. English as a foreign language (EFL) course was administered for 52 university students. The participants were equally divided into TVT and 360VT groups. They attended EFL classes, and after classes, they created videos using either a traditional video camera (TVT group) or a 360-degree video camera (360VT group) on four learning topics. The evaluators watched videos, evaluated them, and then provided feedback to students. Students then revised their works based on received feedback. The results showed an insignificant difference between the two groups in their pre-test scores when measuring prior knowledge. However, when measuring knowledge after the study, 360VT group students outperformed their counterparts in the post-test. According to the results, students in the 360VT group received significantly more feedback, and it was more detailed compared to that of their counterparts. In addition, the evaluators scored affordances of 360VT higher than those of TVT. The results showed many advantages of 360VT such as it was useful and easy to use during the evaluation process, 360VT created immersive environments so that the evaluators had a realistic experience and a high level of vividness when watching and evaluating videos. The results suggest that evaluation and feedback in 360VT environments had better effects on learning outcomes, and the evaluators positively perceived their experiences in 360VT settings. Therefore, it is suggested that educators and researchers consider implementing 360VT in situations when language learners are tasked with creating their own content, which can subsequently be evaluated with relevant feedback provided.

Development and validation of video technology on preparation for colonoscopy in cancer patients

Objective: To construct and validate an educational video with an orientation protocol on preparation for colonoscopy in cancer patients. Methods: This is a methodological study divided into two stages, comprising the production of a video based on a printed protocol on the preparation for colonoscopy recommended by a reference institute for cancer treatment, followed by content validation by expert judges selected because of the adapted Fehring criteria. The Content Validity Index was used for validation, with a cut-off point of 0.78. Reliability was tested using the Kappa coefficient, with values greater than or equal to zero being considered reliable. Results: The educational video lasts approximately 7 minutes and covers the diet to be used on the eve of the colonoscopy exam, the medications used, prohibited foods, start times for preparation and the exam, and post-exam guidelines. 15 expert judges validated the content, obtaining a concordance index of 0.96. Conclusions: The educational video was considered valid by the experts, contributing to nursing in the preparation of cancer patients for colonoscopy. It is suggested that the video be evaluated by cancer patients in a consistent sample.

DEVELOPING CONTENT FOR A VIRTUAL SOCIAL ENGAGEMENT INTERVENTION FOR PERSONS WITH MCI

Abstract Older adults, especially those with mild cognitive impairment (MCI), are at increasing risk of social isolation and loneliness, leading to poorer health outcomes. Video technology has the potential to provide socially and cognitively engaging activities from their homes. We are exploring the benefits of a virtual social engagement intervention in older adults with and without MCI (clinicaltrials.gov NCT05380180). We are using a video-technology called OneClick.chat to present participants with a short presentation followed by conversational breakout groups. One challenge for the intervention development was the selection of content that would be engaging but not too memory demanding and of interest to a broad range of people. We worked with iN2L to design 60 unique events that met predefined criteria: could facilitate conversations, did not rely on episodic memory, covered a range of topics, and reflected a diversity of individuals, identities, cultures, and interests. Events were categorized into five predefined categories: Arts & Culture; Nature, Health, & Wellness; Life Experiences; Science & Technology; and Recreation & Sports. We carefully curated each event to ensure consistency of presentation length, picture type, readability, visibility, number of slides, and audio quality. Presentation format was carefully tested through multiple iterations to ensure the best participant experience. Conversational prompts were designed for each event to stimulate engaging conversations through open-ended questions. During the trial we are gathering data on participants’ preferences for different topics that can guide future iterations. Our systematic process of development can guide content design for research on social engagement interventions.

Comparison Using Intelligent Systems for Data Prediction and Near Miss Detection Techniques

Malaysia ranks third among ASEAN countries in terms of deaths due to accidents, with an alarming increase in the number of fatalities each year. Road conditions contribute significantly to near-miss incidents, while the inefficiency of installed CCTVs and the lack of monitoring system algorithms worsen the situation. The objective of this research is to address the issue of increasing accidents and fatalities on Malaysian roads. Specifically, the study aims to investigate the use of video technology and machine learning algorithms for the car detection and analysis of near-miss accidents. To achieve this goal, the researchers focused on Penang, where the MBPP has deployed 1841 CCTV cameras to monitor traffic and document near-miss accidents. The study utilised the YOLOv3, YOLOv4, and Faster RCNN algorithms for vehicle detection. Additionally, the study employed image processing techniques such as Bird’s Eye View and Social Distancing Monitoring to detect and analyse how near misses occur. Various video lengths (20s, 40s, 60s and 80s) were tested to compare the algorithms’ error detection percentage and test duration. The results indicate that Faster RCNN beats YOLOv3 and YOLOV4 in car detection with low error detection, whereas YOLOv3 and YOLOv4 outperform near-miss detection, while Faster RCNN does not perform it. Overall, this study demonstrates the potential of video technology and machine learning algorithms in near-miss accident detection and analysis. Transportation authorities can better understand the causes of accidents and take appropriate measures to improve road safety using these models. This research can be a foundation for further traffic safety and accident prevention studies.

Effect of ultrasonication on rising characteristics of a single gas bubble

In recent years, ultrasonication has been used to enhance flotation process. Gas bubble is the unique carrier during mineral flotation, and thus its characteristics play an important role. However, the bubble rising characteristics under ultrasound action are not clear. Therefore, this paper aims to investigate the effect of ultrasonication on bubble rising behaviors in deionized water and MIBC (Methyl Isobutyl Carbinol) solution. A laboratory visualization system of bubble motion with ultrasonication was designed based on the high-speed dynamic video technology to record the bubble rising process and analyze bubble rising characteristics. Bubble aspect ratio was found to increase with the surfactant concentration increasing, but the rising velocity was in opposite state. In each solution, a significantly higher bubble sphericity was observed with ultrasonication than that without ultrasonication, conversely, the bubble rising velocity was smaller under the action of ultrasonication. A roughly negative linear relationship was found between the bubble shape and rising velocity, and the ultrasonication diminished this relationship. Marangoni effect was considered as the cause of MIBC affecting the bubble motion, and possible explanations of ultrasonication affecting the bubble motion were given from the perspective of bubble surface wave, cavitation bubble oscillation and sound radiation force.

Impact of Instant Visual Guidance via Video Technology on the Correction of Some Offensive Skills Performance Errors in Basketball

Background: Various methods of instructional feedback, whether provided before, during, or immediately after performance, come in different forms, such as verbal communication, educational booklets, and video technology. Choosing the most suitable feedback method is crucial to help learners pinpoint specific motion segments contributing to errors. Objectives: This study aimed to compare 2 feedback methods and assess their impact on correcting errors in beginners’ basketball skills. The control group received verbal correction during the performance, occasionally supplemented by educational booklets. In contrast, the experimental group received immediate visual correction using video technology right after the performance. Methods: A total of 80 beginner learners participated in this study, randomly divided into the control group (n = 40) and the experimental group (n = 40). The experiment spanned 8 weeks, with two sessions conducted per week. Results: Positive results were observed for both feedback methods when comparing pre- and post-measurements within each group. However, upon comparing post-measurement results between the two groups, the results appeared in favor of the immediate visual correction method. Conclusions: The immediate visual correction method utilizing video technology demonstrated greater effectiveness in rectifying errors in learners’ basketball skills.

An audience studies’ contribution to the discoverability and prominence debate: Seeking UK TV audiences’ ‘routes to content’

Despite discoverability and prominence emerging as crucial to contemporary industry and policy debates in relation to online and internet-distributed television, there remains relatively little rich, qualitative data about how contemporary audiences discover content. This article addresses this gap through empirical audience research focused on the ‘routes to content’ through which UK audiences find and decide what television to watch. Defining television broadly to include all forms of video content accessed in the home, we argue for the importance of thinking about discoverability as an audience activity, not just an industrial strategy. Building on TV audience studies’ longer history and more recent literature on engagement, media literacy, algorithms and technological affordances in contemporary media platforms, we argue for new understanding of the imaginaries shaping people’s habitual viewing activities. The article proposes four new concepts for thinking about discoverability as an audience activity. First, we explore technological affordances and default behaviour, developing the concept of the negotiated-null affordance to explain how technological affordances can be rendered invisible by habitual behaviours. Second, we focus on algorithmic literacies and propose a new dissonant algorithmic imaginary to explain our participants’ ambivalences towards algorithmic personalisation. Third, we unpack the dynamics of access that emerge in our participants’ negotiations of television technologies, services and content. Fourth, we examine the role of word of mouth and promotional paratexts, theorising a second-order algorithmic imaginary to help us understand how these forms of communication can often, themselves, be subject to algorithmic processes. In doing so, we argue for the need for further qualitative research that looks beyond the ‘savvy’ consumers that dominate audience research in order to unpack the technological, industrial, cultural and social processes that shape people’s routes to content in a platform-dominated media landscape.

Effectiveness evaluation of the use of video content to develop professional skills of the future dentist

Annotation. The use of video technologies during practical classes is an integral part of the education of dental students. The aim of our study is to evaluate the effectiveness of the use of video content for developing professional skills among students of the Faculty of Dentistry. Students of two academic groups took part in the study. In the 1st group (main) the class was carried out with the involvement of interactive video films, in the 2nd group (comparative) – according to the traditional method. To achieve the goal of the study, questionnaires were developed for determining the coefficient of self-assessment and checklists for evaluating the coefficient of practical skills. Assessment of the obtained results was performed immediately after studying the topic in the fourth course and during subintership. Statistical processing was carried out using the computer programs “Statistica 6.1” and Microsoft® Excel 2017. The obtained results showed that the level of mastery of practical skills and abilities in the main group is significantly higher (p<0.05) than the results of the comparison group. This indicates the high efficiency of the use of videos in the educational process and can be considered as an alternative in quarantine and martial law conditions, as well as be used for independent extracurricular work in training of students and interactive communication with the teacher. The prospect of further research is the creation of an electronic database of video materials on the topics of classes, mastering and involving other modern interactive teaching technologies in the pedagogical process in order to improve the quality of training of future dentists.

Robust Feature Extraction via ℓ∞-Norm Based Nonnegative Tucker Decomposition

Feature extraction plays an indispensable role in image and video technology. However, it is difficult for traditional matrix based feature extraction methods to handle massive multi-dimensional data. This, alongside with the ubiquitous uncertainty (noise) in real-world data, resulted in many robust tensor based feature extraction models. However, these existing models did not consider the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">worst-case</i> model performance (i.e., the largest fitting error among all samples), which is critically important from a robust optimization perspective. In this paper, we propose a novel robust feature extraction model via ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> -norm based nonnegative Tucker decomposition. The model is to minimize the maximum sample fitting error so as to overcome the influence of data uncertainty. Although the new model is nonconvex and nonsmooth, we design an effective iterative optimization algorithm with theoretical guarantee on its convergence for it. The performance of the new model on five real-world benchmark object classification and face recognition datasets under various corruption scenarios are evaluated, and the experimental results show the excellence of the new model by comparing to many existing models.

Meeting the AACN's Essentials for Competency-Based Education With Hands-Free Video-Recorded Skills Assessment.

In the American Association of Colleges of Nursing's updated Essentials, competency-based education (CBE) is the expected standard for nursing curricula. CBE approaches include observation, practice repetition, demonstration, and video supervision guided by a framework of competency, feedback, and self-reflection. The promotion of skills competency among nursing students was facilitated by self-regulated learning using video skills-based competency testing. Video surveillance enabled students to practice and self-test their competency skills. Self-videotaping by students provided a comfortable learning environment for repeated practice and fostered clinical judgment and accountability. Students reported increased confidence, decreased anxiety, and improved performance. Students developed skills and attitudes regarding self-reflection and self-remediation. Additionally, faculty reported improved visibility, a more efficient workload, and greater achievement of student outcomes. Integrating CBE and incorporating video technology during skills testing enhances the opportunity for students to demonstrate skills competency and gain comfort in their own skills acquisition.

By leveraging the passion and engagement fostered within geek communities, this theory proposes a distinctive avenue for psychological intervention. It explores the prospect of channeling the intrinsic motivation and communal dynamics prevalent in geek culture to enact meaningful and positive changes in individuals' behaviors. This innovative approach signifies a departure from conventional psychological interventions, positioning geek culture as an untapped resource with the potential to redefine the landscape of behavioral change strategies.

Capturing the pulse: a state-of-the-art review on camera-based jugular vein assessment.

Heart failure is associated with a rehospitalisation rate of up to 50% within six months. Elevated central venous pressure may serve as an early warning sign. While invasive procedures are used to measure central venous pressure for guiding treatment in hospital, this becomes impractical upon discharge. A non-invasive estimation technique exists, where the clinician visually inspects the pulsation of the jugular veins in the neck, but it is less reliable due to human limitations. Video and signal processing technologies may offer a high-fidelity alternative. This state-of-the-art review analyses existing literature on camera-based methods for jugular vein assessment. We summarize key design considerations and suggest avenues for future research. Our review highlights the neck as a rich imaging target beyond the jugular veins, capturing comprehensive cardiac signals, and outlines factors affecting signal quality and measurement accuracy. Addressing an often quoted limitation in the field, we also propose minimum reporting standards for future studies.

Taxonomy and Survey of Current 3D Photorealistic Human Body Modelling and Reconstruction Techniques for Holographic-Type Communication

The continuous evolution of video technologies is now primarily focused on enhancing 3D video paradigms and consistently improving their quality, realism, and level of immersion. Both the research community and the industry work towards improving 3D content representation, compression, and transmission. Their collective efforts culminate in the striving for real-time transfer of volumetric data between distant locations, laying the foundation for holographic-type communication (HTC). However, to truly enable a realistic holographic experience, the 3D representation of the HTC participants must accurately convey the real individuals’ appearance, emotions, and interactions by creating authentic and animatable 3D human models. In this regard, our paper aims to examine the most recent and widely acknowledged works in the realm of 3D human body modelling and reconstruction. In addition, we provide insights into the datasets and the 3D parametric body models utilized by the examined approaches, along with the employed evaluation metrics. Our contribution involves organizing the examined techniques, making comparisons based on various criteria, and creating a taxonomy rooted in the nature of the input data. Furthermore, we discuss the assessed approaches concerning different indicators and HTC.

Didactic potential of educational VR films (on the example of the film “Electric power industry of Russia”)

The introduction of modern video technologies into pedagogical practice is one of the ways to increase students’ motivation to learn about the world. The article describes in detail the advantages, methodological purpose, and didactic potential of educational VR films on the example of the film in 360° format “Electric power industry of Russia”, created by a team of employees of The Academy of Public Policy Implementation and Professional Development of Educators of the Ministry of Education of the Russian Federation (The Academy of Ministry of Education of the Russian Federation) for free use in Russian educational organizations.The methodology of the study of educational VR films didactic potential presented in the article is based on the activity approach to learning, the principles of systematicity, and interdisciplinarity. The activity approach in the use of VR film is provided by the maximum effect of presence, which is experienced by the viewer, and independence in the choice of the subject of attention. The work of an active and proactive student is complemented by the activity of a teacher who can guide the student and choose objects from an educational VR film to set learning objectives, and formulate questions and tasks. The principles of systematicity and interdisciplinarity are provided by educational content created on the basis of the integration of knowledge from different subject areas, which allows teachers to use the didactic potential of the VR film in different disciplines and age groups.The proposed methodological solutions for the use of VR film are of practical value for the educational process in a modern school: they contribute to the formation of a holistic view of students about the achievements of Russian science and modern professions (in particular, in the electric power industry), the education of patriotism and pride in the Fatherland, the development of skills of independence and self-control in learning activities.The authors see the development of the project as one of the strategic directions in the field of digital transformation of education, aimed at improving the quality of education of modern schoolchildren.

Telerehabilitation use and experiences in occupational and physical therapy through the early stages of the COVID-19 pandemic.

Telehealth has helped to increase access to rehabilitative services such as occupational and physical therapy. The early COVID-19 pandemic amplified the need for remote access to care, and the rapid implementation of telehealth systems provided a unique opportunity to learn from clinicians' experiences adopting telehealth for telerehabilitation applications. To understand these experiences, a self-administered online survey was conducted to capture perspectives on ease of telerehabilitation use and adoption from occupational and physical therapists. The survey captured retrospective views on telerehabilitation use pre-pandemic as well as real-time perspectives on telerehabilitation during the early stages of the pandemic (July to August 2020). The survey gathered information on clinician demographics (N = 109), clinicians' experiences with adopting or utilizing telerehabilitation systems, and their perceptions on remotely performing cognitive, emotional, and physical assessments via video-conferencing (a common mode of telehealth). Responses demonstrated a modest increase in telerehabilitation as a care setting (rate increase from 3.4% to 19.3%), and telerehabilitation was more generally tried during the early stages of the pandemic (41 clinicians explicitly reported telerehabilitation use). However, technology access and acceptance remained low, with 38 clinicians (35%) expressing concerns that technology was ineffective or impractical, unavailable, not covered by insurance, or not desired by their patients. Video-conferencing technology was perceived as generally ill-equipped to support clinicians in performing remote assessment tasks. Physical assessment tasks were considered particularly difficult, with 55% of clinicians rating their ability to perform these tasks in the range of moderately difficult to unable to perform. To address these difficulties and better augment clinical care, clinicians require more robust assessment methods that may combine video, mobile, and wearable technologies that would be accessible to a patient at home. When designing future telerehabilitation tools, information captured through these modes must be task-relevant, standardized, and understandable to a remote clinician.

A Year After Implementation of the Telehealth Waiver: Being Offered and Utilizing Video-Specific Telehealth Among Dual-Eligible Medicare Recipients During the COVID-19 Pandemic.

Telehealth is an essential tool to provide access to care while reducing infection exposure for high-risk populations during the COVID-19 pandemic. Our study aims to examine factors associated with telehealth availability and usage among Medicare and dual-eligible recipients 1 year after implementation of the Medicare's temporary telehealth waiver. A cross-sectional, phone survey with a national representative sample of Medicare recipients. We obtained a final study sample from the Winter 2021 COVID-19 Supplement of Medicare Current Beneficiary Survey dataset (N = 10 586). We examined associations for being offered and having had telehealth visits or any video telehealth visits during the pandemic since November 1, 2020. Our primary outcomes were being offered any telehealth, being offered any video telehealth, having had any telehealth visit, and having had any video telehealth. Although dual eligibility was not significantly associated with being offered or having had any telehealth services during the pandemic, those who were dual eligible were more likely to have had video telehealth visits (adjusted odds ratio = 1.39, 95% confidence interval 1.04-1.86, P = .03) compared with those with non-dual eligibility. Recipients with disability eligibility, technology access, and severe chronic conditions were more likely to have been offered or have had telehealth. At the same time, those who lived in the nonmetropolitan area were less likely to have been offered or have had telehealth, including video telehealth. Our findings suggest that the federal waivers to expand telehealth services were successful in continuing care for vulnerable Medicare recipients. The providers' specific outreach and intervention efforts to offer telehealth visits are crucial for dual-eligible recipients. To increase video telehealth uptake, technology access and services to rural areas should be prioritized.
