An educational device was created to develop a hands-on activity to illustrate how atherosclerosis can dramatically reduce blood flow in human vessels. The device was conceived, designed, and built at the University of Coimbra, in response to a request from the Exploratório Infante D. Henrique Science Centre Museum, where it is presently installed. The device was designed to allow lay audience to operate it, including school-age youngsters. The two blood flow reduction mechanisms that can be visualized are 1) thickening of the artery wall and 2) hardening of the artery wall. The main objective is to promote the understanding of atherosclerotic cardiovascular physiology by simple and direct experiments. This original educational interactive device was constructed using, in the conceptual and design stages of the project, a Newtonian theoretical flow model based on Poiseuille's equation. This device is driven by human force and provides a visualization of the effect of atherosclerosis on flow. The main aspects relating to its design and construction are described here to explain and disseminate this approach. Throughout more than 4 yr of real operation, this educational device proved to be a simple and attractive way of understanding atherosclerosis, especially among young people.

Non-invasive diagnosis of cardiovascular diseases is a valuable tool to reduce patient’s risk and discomfort. The main aim of this work is to investigate the possibilities of using computational fluid dynamics as a tool to investigate the biomechanical characteristics of the aorta under different medical conditions. These conditions include an aorta with healthy conditions, atherosclerosis and aneurysm. A three dimensional pulsatile flow model for an elastic aorta is developed and constructed in ANSYS® CFX 12. Abnormalities are simulated as diameter changes at the root of the ascending aorta. The computational model shows the reflection of these diseases on the blood flow and the artery wall at other locations downstream along the aorta. This 3D model has several advantages over previously published 1D and 2D models by giving more realistic results as compared with clinical trials.

Abstract Aims Since 2017, medical students at the University of Bergen were taught PET/CT “hands-on” by viewing PET/CT cases in native format on diagnostic workstations in the hospital. Due to the COVID-19 pandemic, students were barred access. This prompted us to launch and evaluate a new freeware PET/CT viewing system hosted in the university network. Methods We asked our students to install the multiplatform Fiji viewer with Beth Israel PET/CT plugin (http://petctviewer.org) on their personal computers and connect to a central image database in the university network based on the public domain orthanc server (https://orthanc-server.com). At the end of course, we conducted an anonymous student survey. Results The new system was online within eight days, including regulatory approval. All 76 students (100 %) in the fifth year completed their course work, reading five anonymized PET/CT cases as planned. 41 (53 %) students answered the survey. Fiji was challenging to install with a mean score of 1.8 on a 5-point Likert scale (5 = easy, 1 = difficult). Fiji was more difficult to use (score 3.0) than the previously used diagnostic workstations in the hospital (score 4.1; p < 0.001, paired t-test). Despite the technical challenge, 47 % of students reported having learnt much (scores 4 and 5); only 11 % were negative (scores 1 and 2). 51 % found the PET/CT tasks engaging (scores 4 and 5) while 20 % and 5 % returned scores 2 and 1, respectively. Conclusion Despite the initial technical challenge, “hands-on” learning of PET/CT based on the freeware Fiji/orthanc PET/CT-viewer was associated with a high degree of student satisfaction. We plan to continue running the system to give students permanent access to PET/CT cases in native format regardless of time or location.

Universities foster a collaboration with industry with their commitment towards society. Corporate social responsibility (CSR) practices of organizations facilitate implementation of the recognition of prior learning (RPL) in higher education, while creating long-term opportunities for sustainable development. The researchers of this study come from two different disciplines, and aim to embed sustainable development strategies for transforming education by utilizing the capacity of educators and industry professionals, while also contributing to the community and economy. The researcher with a specialization in economics identified the well-being of the community and economy, and another researcher with a design and ergonomics background brought the concept of service design. Results of the conducted surveys imply that a skill gap exists in the labor market and participants from the community are interested in receiving hands on training from the industry. The researchers introduce a model focusing on the significance and implementation of RPL, allowing youth and adults to accumulate credit through non-formal and informal learning experiences. The model reflects how the university assesses the current skills and needs of the target communities, how they are communicated to industry by identifying potential areas of development, how industry responds to the needs by providing training, and how the university acknowledges prior learning and promotes potential candidates to contribute towards industry.
