Effectiveness of interprofessional development of foundational lactation open education resources

The purpose of this manuscript is to share the interprofessional development of foundational lactation open education resources (OERs) for prebriefing prior to simulation. A team of health faculty, students, and practitioners developed five lactation modules with an Equity Diversity Inclusion (EDI) framework representing diverse families. Participants (n=1453) answered a survey at the end of the OER modules including a variety of healthcare professional faculty, students, practitioners, and parents. The process of development, effectiveness, and usability of these modules were used for prebriefing prior to teaching/learning opportunities. The findings from use of the five OERs provide descriptive data on the usefulness for interprofessional education and professional development. The creation of five OER lactation modules provide an equity and inclusion lens to model consistent approaches to support the needs of diverse families allowing interprofessional students to develop shared mental models and psychological safety prior to clinical experiences.

Brain-Controlled Hand Exoskeleton Based on Augmented Reality-Fused Stimulus Paradigm.

Advancements in brain-machine interfaces (BMIs) have led to the development of novel rehabilitation training methods for people with impaired hand function. However, contemporary hand exoskeleton systems predominantly adopt passive control methods, leading to low system performance. In this work, an active brain-controlled hand exoskeleton system is proposed that uses a novel augmented reality-fused stimulus (AR-FS) paradigm as a human-machine interface, which enables users to actively control their fingers to move. Considering that the proposed AR-FS paradigm generates movement artifacts during hand movements, an enhanced decoding algorithm is designed to improve the decoding accuracy and robustness of the system. In online experiments, participants performed online control tasks using the proposed system, with an average task time cost of 16.27 s, an average output latency of 1.54 s, and an average correlation instantaneous rate (CIR) of 0.0321. The proposed system shows 35.37% better efficiency, 8.03% reduced system delay, and 35.28% better stability than the traditional system. This study not only provides an efficient rehabilitation solution for people with impaired hand function but also expands the application prospects of brain-control technology in areas such as human augmentation, patient monitoring, and remote robotic interaction. The video in Graphical Abstract Video demonstrates the user's process of operating the proposed brain-controlled hand exoskeleton system.

This study aimed to describe the process of construction, validation, and usability of the chatbot ESTOMABOT to assist in the self-care of patients with intestinal ostomies. Methodological research was conducted in three phases: construction, validation, and usability. The first stage corresponded to the elaboration of a script through a literature review, and the second stage corresponded to face and content validation through a panel of enterostomal therapy nurses. In the third phase, the usability of ESTOMABOT was assessed with the participation of surgical clinic nurses, patients with intestinal elimination ostomies, and information technology professionals, using the System Usability Scale. The ESTOMABOT content reached excellent criteria of adequacy, with percentages of agreement equal to or greater than 90%, which were considered adequate, relevant, and representative. The evaluation of the content validity of the script using the scale content validity index/average proportion method reached a result above 0.90, and the Fleiss κ was excellent (P < .05). The overall usability score of the chatbot was 81.5, demonstrating excellent usability. The script, developed and incorporated into the ESTOMABOT prototype, achieved satisfactory content validity. The usability of the chatbot was considered to be good, thereby increasing the credibility of the instrument.

FCEVAL: An effective and quantitative platform for evaluating fuzzer combinations fairly and easily

Multiple base fuzzers collaborate as a fuzzer combination. Fuzzer combinations have been proven to perform more robustly and efficiently when fuzzing complicated real-world programs. The efficiency of finding bugs with limited computational resources would greatly benefit from the fuzzer combinations chosen by an effective and quantitative performance evaluation. However, evaluating fuzzer combinations remains challenging due to the lack of infrastructure for collaborative fuzzing, high enough collaboration efficiency of base fuzzers, unified benchmarks, comprehensive metrics, and unified analysis methods of coverage and bugs. This prevents us from selecting efficient fuzzer combinations and thus impairs vulnerability mining on real-world targets. In this paper, we design and implement FCEVAL, the first open-source platform for evaluating fuzzer combinations. In detail, we propose a new test case-sharing policy for increasing fuzzing potential so that we can provide a more efficient running environment for fuzzer combinations and thus improve evaluation effectiveness. Also, we select a unified set of diverse benchmarks and comprehensive metrics while adopting unified independent methods of real-time coverage statistics and multiple-sanitizers-based bug analysis for evaluation fairness and quantification. In addition, we design tools and guidelines covering the whole evaluation process for usability. With the above methodologies, we first construct an infrastructure special for collaborative fuzzing as the base of FCEVAL. After comparing two test case-sharing policies on the infrastructure and choosing the promising one as a substantial part of FCEVAL, we leverage FCEVAL to evaluate fuzzer combinations for more than 40,000 CPU hours and come up with five important conclusions, including (a) an efficient test case-sharing policy improving fuzzing potential and thus evaluation effectiveness, (b) comprehensive metrics being essential, (c) 24-hour duration and 20 repetitions for evaluation being substantial, (d) independent analysis methods of code coverage and bugs deserving of extensive adoption, and (e) FCEVAL being able to evaluate fuzzer combinations effectively, fairly, comprehensively, and easily. Meanwhile, we suggest how to improve collaborative fuzzing. In addition, source codes and test data are publicly available.

Finite Element Modeling of Additive Manufacturing in Case of Metal Parts

Metal Additive Manufacturing has grown from 3D metal printing; this technology leads to manufacturing parts using various metallic materials.Additive Manufacturing technology uses the same principle of slicing a solid model into multiple layers and creating a tool path for each layer, then uploading this data to the printing machine and building the part up layer by layer following the sliced model data using a heat source (laser, electron beam, electric arc, or ultrasonic energy, etc.) and feedstock (metal powder, wire or thin metal sheet, etc.).The Additive Manufacturing process starts with designing the prototype, continues with printer pre-processing, then with printing the prototype, and finally with post-processing to get the final part, followed by testing. This sequence has to be repeated till achieving the desired prototype. This method costs money and time. In this paper, the Simufact Additive Manufacturing software makes a virtual simulation to save time and money. In this virtual modelling, different types of materials can be used. Different approaches can be tested, such as building orientations with various parameters, changing supporting structures, and cutting and support removal to achieve a usable process, which is free from damaging effects on the first time that goes through the build. This paper deals with three types of metal alloys (TiAl6V4, AlSi10Mg, and 316L). Different types of machines, thermal analysis, mechanical calibration, thermal and thermomechanical calibration, were applied to find the set parameters such as laser power, inherent strains, exposure energy fraction, and volumetric expansion factor.

A University with its cutting edge state of the art infrastructure heavily relies on communication and information processing from one key location to another. This research paper focuses on Rashtrasant Tukdoji Maharaj Nagpur University. As its case study, and appears at the development of an records processing infrastructure containing hardware and software program modules that are set up and ported on a number key locations within an institute. Although with such excessive precedence of communication, most of the universities nonetheless use a timber word board striking on a wall to show daily announcements or paper primarily based attendance system. The over-reliance of this practice in a college is still now not adequate to skip applicable statistics around. The foremost electricity of the lookup work is its usability and facts processing in the course of the tutorial or business vicinity. The modules include a large spread touch display appearing as a digital notice board showing facts to students. An admin panel that would handle network communication, software interface created via web technology and teacher interface that would upload information to be displayed on the notice board.

So that it can be seen the user's process in interpreting a game, this can be explored with various approaches, one of which is using reception analysis theory. Reception Study (study of acceptance) is one that develops in cultural studies, which focuses on messages or communication discourses and has implications for audiences. In this study, the game "Among Us" contained a narrative or storyline that was presented as well as a visualization of the character design of this game. The goal to be achieved in this research is to find out the meaning of players towards the Among Us game by using a Reception Study (acceptance study) which will focus on interpretive meanings and experiences of users or game users in interacting with game media.

An Interdisciplinary Collaboration to Improve Hypertension Medication Adherence for Older Adults

Hypertension is highly prevalent in older adults (74.5% in ≥60 years) with dire consequences, and adherence to hypertension medications is low (approximately 50%). With increased smartphone use among older adults (81% for 60-69 years, 62% for ≥70 years), technology innovations can improve medication adherence. This symposium highlights the efforts of an innovative interdisciplinary team of experts (clinical, cognitive aging, human factors, health technology) to develop and implement the Medication Education, Decision Support, Reminding, and Monitoring (MEDSReM) system to improve hypertension medication adherence for older adults. MEDSReM is a theory-based, integrated mobile application (app) and companion web portal that educates, supports missed dose decisions, reminds, monitors adherence, and incorporates blood pressure feedback. In this symposium, we describe the interdisciplinary development efforts. Insel et al. will present the theory-based intervention, technology translation, and advancement of the MEDSReM system. Lee et al. will describe the interdisciplinary team and describe the work by the decision support subteam that created the medication formulary and generated an algorithm to guide missed-dose decisions based on pharmacology of aging. Rogers et al. will discuss the education subteam’s development of educational information about hypertension, medications, and adherence for the MEDSReM system. Mitzner et al. will illustrate the instructional support sub-team’s efforts to ensure older adults can interact with both the smartphone app and online portal. Lastly, Hale et al. will describe the user testing subteam’s usability processes including the integration of blood pressure self-monitoring. These efforts will provide insights for other interdisciplinary teams developing technology interventions for older adults.

Data Entry Form Designing Tools and Software Usability in DHIS2.

The advent of configurable software has shifted the implementation of software solutions from total reliance on software developers to towards increased participation of end-users. End-users are now able to create software solutions without the need for writing code but through configuration and customisation. Despite the increasing use of configurable software challenges on designing the software platform architecture, process of testing and usability exists in configurable software. The research aimed at evaluating how available interface elements influence usability in DHIS2. Empirical data was collected by studying the design of custom data collection forms for routine health data collection with two groups of users. 80% and 90% were recorded as completion rates of the designed task and overall efficiency of 86.23% and 89.94% was achieved between the two groups. Lack of relevant editing features, increased distance between related objects, lack of conformity to Keep It Simple, Stupid (KISS) and minimalistic design principle were found to be the major challenges affecting the usability.

Predicting reposting latency of news content in social media: A focus on issue attention, temporal usage pattern, and information redundancy

Social media platforms are increasingly being used as important sources for obtaining various types of information in the current digital age. While an increasing number of studies have investigated the factors that influence user's news content sharing behavior, few have paid attention to the reposting latency of online news contents. Reposting latency refers to the delay of interval time between original post publish time and repost time. Reposting activity on social media is an important type of user feedback behavior to the message received. The speed of the response could reflect user's processing efficiency and capacity. This study examined the possible factors that may influence users' reposting latency of news contents on social media. In doing so, we employed a multilevel negative binomial model to examine the impacts of issue attention, temporal usage pattern, and information redundancy. Our findings show that multiple issues could distract user's attention, thus leading to the low reposting speed. We also found a distributed temporal usage pattern could help shorten reposting time, while information redundancy and information overload could increase the reposting latency of news contents on social media. The findings of this study can contribute to advancing the understanding of news consumption behavior on social media. The conclusions have the potential to help in explaining and further predicting the success of news diffusion.

Usability Testing a Potentially Inappropriate Medication Dashboard: A Core Component of the Dashboard Development Process.

Background With the increased usage of dashboard reporting systems to monitor and track patient panels by clinical users, developers must ensure that the information displays they produce are accurate and intuitive. When evaluating usability of a clinical dashboard among potential end users, developers oftentimes rely on methods such as questionnaires as opposed to other, more time-intensive strategies that incorporate direct observation. Objectives Prior to release of the potentially inappropriate medication (PIM) clinical dashboard, designed to facilitate completion of a quality improvement project by clinician scholars enrolled in the Veterans Affairs (VA) workforce development Geriatric Scholars Program (GSP), we evaluated the usability of the system. This article describes the process of usability testing a dashboard reporting system with clinicians using direct observation and think-aloud moderating techniques. Methods We developed a structured interview protocol that combines virtual observation, think-aloud moderating techniques, and retrospective questioning of the overall user experience, including use of the System Usability Scale (SUS). Thematic analysis was used to analyze field notes from the interviews of three GSP alumni. Results Our structured approach to usability testing identified specific functional problems with the dashboard reporting system that were missed by results from the SUS. Usability testing lead to overall improvements in the intuitive use of the system, increased data transparency, and clarification of the dashboard's purpose. Conclusion Reliance solely on questionnaires and surveys at the end stages of dashboard development can mask potential functional problems that will impede proper usage and lead to misinterpretation of results. A structured approach to usability testing in the developmental phase is an important tool for developers of clinician friendly systems for displaying easily digested information and tracking outcomes for the purpose of quality improvement.

Characterization and control of energetic deposits from hexachlorodisilane in process tool exhaust lines

This work aims to characterize and develop a disposal method for a gel-like deposit generated in a vacuum foreline of an atomic layer deposition (ALD) tool that is using hexachlorodisilane (Si2Cl6, HCDS) as a precursor. This ALD foreline gel was reproduced by replicating the ALD tool process conditions by using a benchtop system that was a 1/85 scale down of one user's process. All samples were tested for shock sensitivity using the Fall hammer apparatus. Extensive infrared studies were done for unhydrolyzed and hydrolyzed gel. Dissolution tests were conducted to develop a method for removing and disposing the gel off-site. Many different solutions such as solvent based solutions, water based alkaline solutions and alcohol based alkaline solutions were tested. It was found that alcohol based alkaline solutions produced only hydrogen as a byproduct and were considered satisfactory for off-site abatement of gel. Furthermore, in-situ cleaning gel of the foreline using a fluorine/N2 mixture with a concentration of 1–10vol% was done. They were all effective in cleaning/removing the gel under the condition of ambient temperature and reduced pressure. Finally, recommended procedures were given for removing as well as disposing the ALD gel.

Augmenting the Business Intelligence Lifecycle Model with Usability: Using eye‑Tracking to Discover the why of Usability Problems

Humans and machines generate data at an alarming rate but still struggle to analyse and process this data fast enough. In order to meet this rising demand, business intelligence (BI) software firms are constantly incorporating new reporting or analytical functionalities in their software. At the same time, in order to be used optimally, they must ensure these features do not overwhelm users. There has however recently been cases where organisations, even after significant monetary investments, fail to realise the full potential of BI tools, sometimes reporting less than 20% utilisation. The purpose of this study was to investigate possible causes of the low utilisation and test the inclusion of a BI usability process. The study uses an off‑the‑shelf tool as a matter of convenience but proposes that including an empirical evaluation process as part of the BI design and development could increase BI adoption and usage. A small feasibility study was conducted to determine whether eye‑tracking is viable as a means of determining why the usability problems exist. Findings suggest that analysis of eye‑tracking data, together with traditional usability measures offer insight into how users solve problems and use the BI tool. Therefore, it will be a valuable aid in the design and testing of BI tools before release to enhance the usability therefore and potentially increase adoption and usage rates and should be included as a phase in the design and development lifecycle.
