VR Video Storytelling for Intangible Cultural Heritage Preservation.

Interactive digital storytelling has become a popular method for virtual cultural heritage presentations. Combinations of stories and 3D virtual reconstructions are attractive for the audience and have high edutainment values. In this paper we investigate if 360◦ VR videos further contribute to user immersion in the preservation of intangible cultural heritage. It describes a case study of the Mostar bridge diving project, aimed to present and preserve the bridge diving tradition from the Old Bridge in Mostar, Bosnia and Herzegovina. It is a virtual reality application which enables the user to virtually jump off the bridge after watching 360◦ video stories about its history and the bridge diving tradition and upon successfully completing the quiz evaluation of the knowledge gained from the stories. The user experience evaluation study shows that our method was successful in preserving a form of intangible heritage and posits suggestions that can be used in developing an intangible heritage preservation framework

Constructing Product-Line Safety Cases from Contract-Based Specifications

Safety cases are used to argue that safety-critical systems satisfy the requirements that are determined to mitigate the potential hazards in the systems operating environment. Although typically a manual task, safety cases have been successfully created for systems without many configuration options. However, in highly configurablesystems, typically developed as a Product Line (PL), arguing about each possible configuration, and ensuring the completeness of the safety case are still open research problems. This paper presentsa novel and general approach, based on Contract-Based Specification(CBS), for the construction of a safety case for an arbitrary PL. Starting from a general CBS framework, we present a PL extension that allows expressing configurable systems and preserves the properties of the original CBS framework. Then, we define the transformation from arbitrary PL models, created using extended CBS framework, to a safety case argumentation-structure, expressed using the Goal Structuring Notation. Finally, the approach is exemplified on a simplified, but real, and currently produced system by Scania CV AB.QC 20190521</p

426. COVID-19 Infection Prevention Practices That Exceed CDC Guidance: Balancing Extra Caution Against Impediments to Care

Abstract Background At the outset of the COVID-19 pandemic, healthcare workers (HCWs) raised concerns about personal risks of acquiring infection during patient care. This led to more stringent infection prevention practices than CDC guidelines during a time of uncertainty about transmission and limited U.S. testing capacity. Hospitals were challenged to protect against true COVID-19 exposure risks, while avoiding use of unproven measures that could interfere with timely, high quality care. We evaluated hospital experiences with HCW COVID-19 exposure concerns impacting clinical workflow/management. Methods We conducted a 32-question structured survey of hospital infection prevention leaders (one per hospital) from CDC Prevention Epicenters, University of California (CA) Health system, HCA Healthcare, and the Southern CA Metrics Committee between May–Dec, 2020. We assessed facility characteristics and COVID-19 exposure concerns causing changes in respiratory care, procedure delays/modifications, requests to change infection prevention processes, disruptions in routine medical care, and health impacts of PPE overuse. Percentages were calculated among respondents for each question. Results Respondents represented 53 hospitals: 22 (42%) were small (&lt; 200 beds), 14 (26%) medium (200-400 beds), and 17 (32%) large ( &gt;400 beds) facilities. Of these, 11 (21%) provided Level 1 trauma care, and 22 (41%) provided highly immunocompromised patient care; 75% had cared for a substantial number of COVID-19 cases before survey completion. Majority reported changes in respiratory care delivery (71%-87%), procedural delays (75%-87%), requests to change infection prevention controls/protocols (58%-96%), and occupational health impacts of PPE overuse including skin irritation (98%) and carbon dioxide narcosis symptoms (55%) (Table). Conclusion HCW concerns over work-related COVID-19 exposure contributed to practice changes, many of which are unsupported by CDC guidance and resulted in healthcare delivery delays and alterations in clinical care. Pandemic planning and response must include the ability to rapidly develop evidence to guide infection prevention practice. Disclosures Shruti K.

Improving Accessibility to Intangible Cultural Heritage Preservation using Virtual Reality.

Presentations of virtual Cultural Heritage artifacts are often communicated via the medium of interactive digital storytelling. The synergy of a storied narrative embedded within a 3D virtual reconstruction context have high consumer appeal and edutainment value. We investigate if 360◦ videos presented through virtual reality further contribute to user immersion for the application of preserving Intangible Cultural Heritage. A case study then analyses whether conventional desktop media is significantly different than virtual reality as a medium for immersion in intangible heritage contexts. The case study describes bridge diving at Stari Most, the old bridge in Mostar Bosnia. This application aims to present and preserve the bridge diving tradition at this site. The project describes the site and history along with cultural connections, a series of quiz questions are presented after viewing all of the materials. Successful completion of the quiz allows a user to participate in a virtual bridge dive. The subjective evaluation provided evidence to suggest that our method is successful in preserving intangible heritage and communicating ideas in key areas of concern for this heritage that can be used to develop a preservation framework in the future. It was also possible to conclude that experience within the VR framework did not affect Effort Expectancy for the web application, but the same experience made a significant influence for the Performance Expectancy construct
