Objective: We determine whether an ecological interface display for nuclear power plant operations supports improved situation awareness over traditional and user-centered displays in a realistic environment. Background: Ecological design (EID) has not yet been fully evaluated with real operators facing scenarios. Method: were alongside “advanced” full-scope simulation. Licensed used the scenarios that either had procedural support or did have support. All three their ability to operator...

Pulsed shortwave therapy (PSWT) is a nonpharmacologic/noninvasive modality that may offer analgesic benefits without notable side effects or complications. This pilot study aimed to assess the feasibility of PSWT protocol and provide an estimate its treatment effects. The included adults who underwent cholecystectomy unilateral total hip knee arthroplasty. Participants were randomized eight days either with single functioning device (SofPulse, Endonovo Therapeutics, Woodland Hills, CA) sham...

This study investigated the association between driving safety and seven sleep disorders amongst 3541 participants of Second Strategic Highway Research Program (SHRP 2) naturalistic study.SHRP 2 collected data from 16 98 years old by instrumenting participants' vehicles. The analyses used logistic regression to determine likelihood crash or near-crash involvement, Poisson log-linear assess rate, ordinal driver maneuver appropriateness severity. These did not account for any medical...

Laboratory studies have shown that ecological interfaces can enhance operator performance in process control. However, limited verification and validation representative settings are impeding the adoption of Ecological Interface Design (EID) framework nuclear domain. A companion article presents an application EID to secondary side a boiling water reactor plant simulator, demonstrating lead display features criteria relevant supporting operators both anticipated unanticipated situations....

Distracted driving contributes to a significant portion of vehicle accidents and deaths. To mitigate distracted driving, the University Virginia Center Promote Effective Youth Development sponsored development noninvasive system detect warn drivers their distraction. This warning is installed in medium-fidelity simulator Driving Safety Laboratory (VDSL). The composed (i) Microsoft Kinect motion sensing hardware for tracking head skeletal movements (ii) custom software application identifying...

Objective: The aim of this study was to apply work domain analysis for cybersecurity assessment and design supervisory control data acquisition (SCADA) systems. Background: Adoption information communication technology in cyberphysical systems (CPSs) critical infrastructures enables automated distributed but introduces risk. Many CPSs employ SCADA industrial that have become the target cyberattacks, which inflict physical damage without use force. Given absolute security is not feasible...

Accident investigations have revealed that unanticipated events are often precursors of major accidents. Unfortunately, conventional approaches to interface design for complex systems do not explicitly support problem solving during events. Ecological Interface Design (EID) is a theoretical framework designing computer interfaces aims worker adaptation, especially events, leading more robust user interfaces. However, limited verification and validation research in representative settings...

This paper presents a novel cable-driven exoskeleton (BiEXO) for the upper limb including shoulder and elbow joints. BiEXO is made of carbon fiber that inspired by Bamboo structure. The key components are tubes mimic bamboo tubes. A combined driver developed with two mechanisms (CDMs) power transmission belt (PTB). CDMs used flexion/extension movement utilizing cables to skeletal muscle's function, while PTB system drives link scapula joint abduction/adduction movement. Simulation studies...

Patient flow management is a system-wide process but many healthcare providers do not integrate multiple departments into the to minimise time between treatments or medical services for maximum patient throughput. This paper presents case study of applying Distributed Situation Awareness (DSA) characterise and identify opportunities improvements in system. employed three-part method data elicitation, extraction, representation investigate DSA. Social, task, knowledge networks were developed...

As machine learning approaches ubiquity in industrial systems and consumer products, human factors research must attend to learning, specifically on how intelligent built are different from early generations of automated systems, what these differences mean for human-system interaction, design, evaluation training. This panel invites five researchers domains discuss can contribute applications, as well presents both challenges contributions factors.

The increasing number of senior drivers may introduce new road risks due to age-related declines in physical and cognitive abilities. Advanced driver assistance systems (ADAS) have been proposed as solutions minimize declines, thereby both safety mobility. This study examined factors that influence seniors' attitudes toward adopting ADAS after significant exposure the technology naturalistic settings.This recruited 18 aged 70-79 drive vehicles equipped with for 6 weeks their own...

The Process Overview Measure is a query-based measure developed to assess operator situation awareness (SA) from monitoring process plants. A companion paper describes how the has been according plant properties and cognitive work. demonstrated practicality, sensitivity, validity reliability in two full-scope simulator experiments investigating dramatically different operational concepts. Practicality was assessed based on qualitative feedback of participants researchers. sensitivity by...

Introduction: On November 8, 2013, Super Typhoon Haiyan struck the Philippines, causing a humanitarian emergency.According to World Health Organization, non-communicable diseases (NCDs), also known as chronic diseases, are leading cause of death and disability around world.NCDs kill 38 million people each year.Sixteen NCD deaths occur before age 70; 82% which occurred in low-and middle-income countries.NCDs further exacerbated during crisis, addressing them should be concern any medical...

Abstract Background Spatial problem‐solving is an essential skill for success in many engineering disciplines; thus, understanding the cognitive processes involved could help inform design of training interventions students trying to improve this skill. Prior research has yet investigate differences between spatial tasks offer learners timely feedback. Purpose/Hypothesis In study, we investigated how different change and strategies used by with low ability. Design/Method Study participants...

Virtual reality (VR) has emerged as a promising tool for training novice forklift drivers, but temporal patterns of such improvements are largely unknown. We trained 19 participants using an order-picker VR simulator on selected driving lesson. In two sessions, participant performance was assessed task completion time and kinematics the head, shoulder, lumbar spine via inertial measurement units (IMUs). Completion head flexion/movement decreased significantly (up to 22.4% 31.5%,...

A full-scope simulation study with licensed nuclear power plant operators was conducted to evaluate whether displays designed using Ecological Interface Design (EID) could support improved Situation Awareness over traditional displays. EID demonstrated performance advantages in beyond-design basis scenarios where were unable rely on procedures. The same effects not seen within-design procedures available. This suggests that has the potential improve SA unanticipated situations, but...

Review of the literature reveals that different treatments and applications situation awareness (SA) theories measures often include reference to, or verification from, specific domains. This leads to postulate application domain from which a conceptualization SA arises plays fundamental role in conceptualization. To test this postulate, we compare accounts originating three domains -aviation, military command control, process control. The comparison illustrates origin can have significant...
