This study investigated technological barriers affecting safe and effective pediatric mental and behavioral healthcare in emergency departments through observational studies and semi-structured interviews with 55 medical professionals across four ED settings: pediatric MBH unit, pediatric ED, and adult ED. A total of 12 barrier themes were identified through the thematic analysis of the interviews relating to technology use that impacts the care of pediatric MBH patients. The major themes include issues due to limited electronic medical record data management, ineffective communication in the ED, and usability issues with ED technologies. Other concerns included inadequate infrastructure, absence of streamlined processes, unsafe and inefficient integration of technology, and lack of training. Challenges stemming from patients' reluctance to accept telepsychiatry further complicate providing effective care in these settings.

A pre-prescription intervention for fluoroquinolone antibiotics via a computerized clinical decision support tool called a \"best practice alert\" (BPA) embedded in the patient's electronic health records has high potential for improving antibiotic stewardship.

Hence, methods are needed to observe resilience across multiple layers of coordination comprising DT-enabled space missions. This presented study simulates high-stakes scenarios to measure constructs like relaxation time, information entropy, and average mutual information (AMI) to evaluate team responses to perturbations. Our study involved two scenarios: one with nominal communications among space entities and another introducing resilience through deliberate perturbations. Eight participants who were members of the research team, engaged in these simulations. Communication flow and vehicle controls and position were measured. Using layered dynamics, we measure dynamic resilience curves (comprising enaction, adaptation, and recovery components) across the system before, during, and after perturbations. We ran two engineering tests of our resilience metrics. Key findings indicate that measures differentiated between the resilient team with shorter relaxation times and more effective adaptation to perturbations, marked by distinct phases of enaction, adaptation, and recovery. The AMI metric was found to be a more sensitive measure of team influence and resilience than communication frequency. This study contributes to future research in two ways. First, the simulation environment and continuous signal capture allows for the observation of adaptations. Second, the adoption of operationism provides an innovative approach to observing resilience.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"124 ","pages":"Article 104409"},"PeriodicalIF":3.1,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This emphasis on a human-centered approach is a vital aspect in promoting resilience within manufacturing operations. In response, humans need to adjust to new working conditions, including sharing areas with no apparent separations and with simultaneous actions that might affect performance. At the same time, wearable technologies and applications with the potential to gather detailed and accurate human physiological data are growing rapidly. These data lead to a better understanding of evaluating human performance while considering multiple factors in human–robot collaboration. This study uses an approach for assessing human performance in human–robot collaboration. The assessment scenario necessitates understanding of how humans perceive collaborative work based on several indicators, such as perceptions of workload, performance, and physiological feedback. The participants were evaluated for around 120 min. The results showed that human performance improved as the number of repetitions increased, and the learning performance value was 92%. Other physiological indicators also exhibited decreasing values as the human performance tended to increase. The findings can help the industry to evaluate human performance based on workload, performance, and physiological feedback information. The implication of this assessment can serve as a foundation for enhancing resilience by refining work systems that are adaptable to humans without compromising performance.</div></div>","PeriodicalId":55502,"journal":{"name":"Applied Ergonomics","volume":"124 ","pages":"Article 104425"},"PeriodicalIF":3.1,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to explore the relationship between motion sickness induced by ship rolling and muscle activity in various sitting postures, with the goal of informing the optimization of ship seat designs to enhance passenger comfort. The research focuses on the angle of backrest inclination and head-neck position as key variables. Participants were seated on a six-degree-of-freedom platform simulating ship movements and rated their discomfort levels in different sitting postures while electromyographic (EMG) signals were collected from the sternocleidomastoid (SCM), upper trapezius muscles, and erector spinae muscles. The analysis investigated the correlation between muscle activity and motion sickness across different postures. The results indicate that a 22.5° reclined backrest angle minimizes motion sickness discomfort, while no significant correlation was found between head and neck position and motion sickness in this study, but the interaction between head and neck position and backrest angle needs further study. Differences in muscle activity were identified between motion-susceptible and non-susceptible individuals, with the former exhibiting higher activity in the SCM and upper trapezius muscles, leading to greater fatigue. Additionally, only the SCM showed opposite activity between men and women, while the changes in the upper trapezius and erector spinae muscles were basically the same. This study provides insights for optimizing ship seat design, contributing to the alleviation of motion sickness symptoms and enhancing passenger comfort.
