Policymakers face complex tradeoffs in their efforts to achieve global food security. One way to better understand tradeoffs of alternative interventions may come from practicing in simulated environments in a participatory fashion. Serious games employing agent-based simulation have been designed to practice individual and group decision-making in complex domains such as healthcare and sustainability,...
The slowly-adapting type I mechanoreceptor (SA-I) exhibits variability in its steady-state firing rate both within an afferent upon repeated stimulation and between afferents. Additionally, inter-spike intervals of the SA-I are extremely variable during this steady-state firing. While variability of the SA-I response has been noted previously, the work presented herein provides a finer analysis of...
Virtual reality (VR) simulation of tube thoracostomy may improve the procedural training for medical and nursing students. Current VR simulators, however, do not provide tactile feedback, which is essential for enabling certain tasks (e.g., surface palpation to identify rib location, blunt dissection for access to pleural space surrounding the lungs, and finger sweep to confirm location in the pleural...
The most effective screening for prostate cancer combines the prostate specific antigen blood test with the digital rectal examination (DRE). In performing a DRE, two sequential tasks are completed: ( taska) palpating the prostate to identify abnormalities and ( taskb) linking identified abnormalities to a disease diagnosis. At present, clinicians find too few abnormalities and have variable rates...
Nearly all U.S. medical and nursing schools have begun to incorporate simulation in their curriculum. Among various delivery technologies, virtual environments offer unique means for measuring trainee performance and providing objective feedback. Knowledge of onepsilas own performance helps in increasing level of proficiency. This work incorporates objective performance metrics into a virtual reality...
The mechanoreceptors distributed in the finger provide a perceptual interface with our physical world. Slowly adapting type I (SA-I) mechanoreceptors translate mechanical stimulation to neural response and inform our sense of touch. This paper sought to develop a 3-D finite element model of the fingertip to help better understand how the mechanics of the skin impact SA-I mechanoreceptor response....
Cancer of the prostate is diagnosed at a high rate in American men and leads to a high number of deaths annually. Each of the three separate prostate diseases (benign prostatic hypertrophy, prostatitis, and cancer) has different palpable characteristics and requires different treatment. Therefore healthcare professionals must learn to correctly detect and diagnose each prostate abnormality. The digital...
Most virtual reality simulators are designed for complex medical procedures, such as laparoscopic surgery. While important, these simulators are of use for only a subset of specialized doctors. There is a need for simulators that train clinicians to perform more common procedures, such as chest tube insertion, which all medical students must learn. This work describes the design of a virtual reality...
