BACKGROUND: Individuals with physical disabilities experience higher rates of chronic health conditions than individuals without physical disabilities. Self-management programs that use health coaching are effective at eliciting health behavior change in health outcomes such as goal setting, adherence, and health care use. Additionally, web-based resources such as telehealth-based technologies, including SMSS text messaging, web-based applications, and educational multimedia content, can complement health coaching to improve health-related behaviors and the use of health services...

BACKGROUND: Medical education increasingly relies on digital learning materials. Despite recognition by the Association of American Medical Colleges Institute for Improving Medical Education, medical education design often fails to consider quality multimedia design principles. Further, the AAMC-IIME issued a call to study the role of design principles in medical education. Thus, the current study investigated the cognitive and affective effects of redesigning PowerPoint slides used to support pharmacology content during the preclinical years of medical school training...

Body posture estimation has been a hot branch in the field of computer vision. This work focuses on one of its typical applications: recognition of various body postures in sports scenes. Existing technical methods were mostly established on the basis of convolution neural network (CNN) structures, due to their strong visual information sensing ability. However, sports scenes are highly dynamic, and many valuable contextual features can be extracted from multimedia frame sequences. To handle the current challenge, this paper proposes a hybrid neural network-based intelligent body posture estimation system for sports scenes...

Effectively summarizing and re-expressing video content by natural languages in a more human-like fashion is one of the key topics in the field of multimedia content understanding. Despite good progress made in recent years, existing efforts usually overlooked the emotions in user-generated videos, thus making the generated sentence a bit boring and soulless. To fill the research gap, this paper presents a novel emotional video captioning framework in which we design a Vision-based Emotion Interpretation Network to effectively capture the emotions conveyed in videos and describe the visual content in both factual and emotional languages...

Amongst all types of cancer, breast cancer has become one of the most common cancers in the UK threatening millions of people's health. Early detection of breast cancer plays a key role in timely treatment for morbidity reduction. Compared to biopsy, which takes tissues from the lesion for further analysis, image-based methods are less time-consuming and pain-free though they are hampered by lower accuracy due to high false positivity rates. Nevertheless, mammography has become a standard screening method due to its high efficiency and low cost with promising performance...

BACKGROUND: In addition to providing patient care, interprofessional health care teams work collaboratively on a variety of projects. These projects often benefit from using facilitated small group project discussion sessions, such as the Harvard Macy Institute's (HMI) Step Back Process (SBP). Although having a trained facilitator is an important component of the SBP, only a limited number of health care professionals can attend HMI courses in person or virtually, limiting its impact...

There have been major advances in the science to predict the likely environmental concentrations of nanomaterials, which is a key component of exposure and subsequent risk assessment. Considerable progress has been since the first Material Flow Analyses (MFAs) in 2008, which were based on very limited information to more refined current tools that take into account engineered nanoparticle (ENP) size distribution, form, dynamic release, and better-informed release factors. These MFAs provide input for all environmental fate models (EFMs), that generate estimates of mass flows and concentrations in various environmental compartments...

Although engineered nanomaterials (ENMs) have tremendous potential to generate technological benefits in numerous sectors, uncertainty on the risks of ENMs for human health and the environment may impede the advancement of novel materials. Traditionally, the risks of ENMs can be evaluated by experimental methods such as environmental field monitoring and animal-based toxicity testing. However, it is time-consuming, expensive, and impractical to evaluate the risk of the increasingly large number of ENMs with the experimental methods...

Image manipulation is easier than ever, often facilitated using accessible AI-based tools. This poses significant risks when used to disseminate disinformation, false evidence, or fraud, which highlights the need for image forgery detection and localization methods to combat this issue. While some recent detection methods demonstrate good performance, there is still a significant gap to be closed to consistently and accurately detect image manipulations in the wild. This paper aims to enhance forgery detection and localization by combining existing detection methods that complement each other...

As academic libraries shift services to meet the changing needs of patrons after the COVID-19 pandemic, educational technologies and services to support them require updating. Patrons using technology that was once associated with hands-on learning and in-person interactions are preferring flexible and hybrid iterations. In this case study, the authors describe and analyze the pivot of three technology services at the Spencer S. Eccles Health Sciences Library in the post-COVID-19 environment. Technologies discussed include a multimedia studio, virtual reality (VR), and a three-dimensional (3D) printing service...

Online environments, such as metaverses, provide distinct social environments for people to engage in complex, cognitive, and multidirectional learning and meaning-making experiences. These engaging and influential environments highlight important factors associated with the Social Learning Theory (a process through which external settings influence behavior in specific environments). According to this theory, environments provide a space for youth to engage in reciprocal interactions of interpersonal, behavioral, and environmental cues...

The Metaverse, powered by a variety of key innovative technologies including 3D virtual reality (VR)/augmented reality (AR), artificial intelligence (AI), blockchain/cryptocurrency-based non-fungible tokens (NFTs), and the Internet of Things, has been proposed as the future of a virtual universe for education, work, business, and commerce. This research (∑ N  = 954) presents the results of three cross-sectional surveys that examine the influence of third-level digital (in)equality and consumer (mis)trust on Metaverse adoption intention...

Immersive virtual reality (IVR) technology provides several educational affordances that make it a valuable tool for learning, especially from a constructivist learning perspective. Combined with the increasing availability of Metaverse social platforms, such as ENGAGE and AltSpace VR, where students and teachers can meet and work together, IVR may transform how students learn and interact with educational content. However, little is known about students' attitudes toward IVR in education. To address this gap, we surveyed 329 undergraduate students from different universities in Italy...

Recent years have witnessed the emergence of various techniques proposed for text-based human face generation and manipulation. Such methods, targeting bridging the semantic gap between text and visual contents, provide users with a deft hand to turn ideas into visuals via text interface and enable more diversified multimedia applications. However, due to the flexibility of linguistic expressiveness, the mapping from sentences to desired facial images is clearly many-to-many, causing ambiguities during text-to-face generation...

BACKGROUND: Globally, tertiary teachers are increasingly being pushed and pulled into online teaching. While most developments in online education have focused on the student perspective, few studies have reported faculty development (FD) initiatives for increasing online teaching capability and confidence from a staff perspective. METHODS: We designed and evaluated FD workshops, using five datasets, and the use of H5P software for interactive online teaching. We used educational theory to design our FD (Mayer multimedia principles, active learning) and evaluated our FD initiatives using the Best Evidence Medical Education (BEME) 2006 modified Kirkpatrick levels...
