Alternative ventilation system for operating theaters: parameter study and full-scale assessment of the performance of a local ventilation system

A local operating theater ventilation device to specifically ventilate the wound area has been developed and investigated. The ventilation device is combined with a blanket which lies over the patient during the operation. Two configurations were studied: Configuration 1 where HEPA-filtered air was supplied around and parallel to the wound area and Configuration 2 where HEPA-filtered air was supplied from the top surface of the blanket, perpendicular to the wound area. A similar approach is investigated in parallel for an instrument table. The objective of the study was to verify the effectiveness of the local device. Prototype solutions developed were studied experimentally (laboratory) and numerically (CFD) in a simplified setup, followed by experimental assessment in a full scale mock-up. Isothermal as well as non-isothermal conditions were analyzed. Particle concentrations obtained in proposed solutions were compared to the concentration without local ventilation. The analysis procedure followed current national guidelines for the assessment of operating theater ventilation systems, which focus on small particles (<10 mm). The results show that the local system can provide better air quality conditions near the wound area compared to a theoretical mixing situation (proof-of-principle). It cannot yet replace the standard unidirectional downflow systems as found for ultraclean operating theater conditions. It does, however, show potential for application in temporary and emergency operating theaters

Operating Systems for the Metamorphoses

Implementing Medical Technological Equipment in the OR

from the Article: "Operating rooms (ORs) more and more evolve into high-tech environments with increasing pressure on finances, logistics, and a not be neglected impact on patient safety. Safe and cost-effective implementation of technological equipment in ORs is notoriously difficult to manage, specifically as generic implementation activities omit as hospitals have implemented local policies for implementations of technological equipment. )e purpose of this study is to identify success factors for effective implementations of new technologies and technological equipment in ORs, based on a systematic literature review. We accessed ten databases and reviewed included articles. )e search resulted in 1592 titles for review, and finally 37 articles were included in this review. We distinguish influencing factors and resulting factors based on the outcomes of this research. Six main categories of influencing factors on successful implementations of medical equipment in ORs were identified: “processes and activities,” “staff,” “communication,” “project management,” “technology,” and “training.” We identified a seventh category “performance” referring to resulting factors during implementations. We argue that aligning the identified influencing factors during implementation impacts the success, adaptation, and safe use of new technological equipment in the OR and thus the outcome of an implementation. The identified categories in literature are considered to be a baseline, to identify factors as elements of a generic holistic implementation model or protocol for new technological equipment in ORs."

Mixing realities: reflections on presence and embodiment in intermedial performance design of Blue Hour VR

Created for the 2019 Prague Quadrennial’s 36Q°, Blue Hour VR was a site-responsive mixed reality performative installation that placed the spectator, as experiencer, within a hybrid landscape of real- time three-dimensional computer graphics and 360-degree video. This article describes the design process, staging and experience of Blue Hour VR from the vantage point of its creators. Using a phenomenological perspective, the article discusses how Blue Hour VR staged presence and embodiment within an intermedial haptic experience. Blue Hour VR demonstrates how virtual reality technology can be harnessed by a mixed reality performance design, which includes both the material and virtual environment, creating a complex stratigraphy of intermedial textures and visual dramaturgies that co-exist inside, outside and in between perceptual realities. In doing so, the article aims to contribute to the limited body of work on mixed and virtual reality in the context of theatre and performance design.

Art as encounter

In this essay I will discuss the specific nature of art practices in which the artist and his audience are moving away from the more traditional relationship in which the artist merely displays his art in museums or public spaces. They consist of intimate and personal processes made possible by the grace of the artistic space that is separating itself from the coded space around it. In these practices the public takes on a different role than that of the passive spectator. The involvement of the public in what art is and can be becomes part of the experience. This turns art into something to be a part of rather than something that is simply handed over to you. More specifically, these art practices allow for a time and site-specific situated form of co-ownership, through which the artistic environment created by the artist becomes the condition for experiencing new ideas and insights. In relation to theatre, the French philosopher Jacques Rancière (1940-) writes in The Emancipated Spectator (2015) about “a theater without an audience” that “no longer tempts with its images but teaches the audience something that turns them into active participants rather than passive voyeurs”. (Rancière 2015: 9-10) These practices are not new. New is perhaps the shift of focus from public participation in processes of interaction towards developing a theatrical space that not only makes other types of expression possible, but also taking on other roles and with that, other perspectives. This notion will therefore be the main focus of this text.

From web 1.0 to web 4.0: the digital heritage platforms for UNESCO’s heritage properties in Indonesia.

The advent of information and communication technologies (ICTs) has had and is having a major impact on Indonesian cultural resource management, and on the safeguarding methods of its tangible and intangible cultural heritages. Despite varied levels and visible gaps between rural and urban regions in terms of technology usage, innovative initiatives have been created, which correspond to the needs and expectations of a technology-savvy public. As a starting point, a number of public institutions dealing with tangible cultural heritage (e.g. museums, palaces, temples, World Heritage Sites (WHS) do use innovative digital tools in order to communicate to various audiences, as well as to enrich visitors' experience, especially taking into consideration young generations. This paper will firstly examine the role of ICTs in intangible cultural heritage (ICH) (e.g. Batik, Wayang puppet theatre, etc.); secondly, the authors will explain how ICTs can help to communicate and promote the values, history, and significances of ICH products, both for locals and tourists, with the goal of raising awareness on cultural identity. However, the knowledge of ICH still requires contacts with its own communities and is vulnerable, as it can be exposed to excessive cultural commoditization through e-platforms. This study aims at giving an overview and some examples of digital interventions for cultural heritage communication implemented by various stakeholders in Indonesia. In addition, this paper analyses to what extent a participatory approach engaging local communities, academics, private sectors, NGOs and the government, can ensure higher levels of effectiveness and efficiency, hence supporting the conservation of UNESCO tangible/ICH in Indonesia. This paper aims at: (1) presenting the development of digital heritage platforms in Indonesia; (2) providing a grid of analysis of digital heritage knowledge platforms dedicated to UNESCO tangible and ICH in forms of websites and mobile apps.
