BackgroundFrequent attendances of the same users in emergency departments (ED) can intensify workload pressures and are common among children, yet little is known about the characteristics of paediatric frequent users in EDs.AimTo describe the volume of frequent paediatric attendance in England and the demographics of frequent paediatric ED users in English hospitals.MethodWe analysed the Hospital Episode Statistics dataset for April 2014–March 2017. The study included 2 308 816 children under 16 years old who attended an ED at least once. Children who attended four times or more in 2015/2016 were classified as frequent users. The preceding and subsequent years were used to capture attendances bordering with the current year. We used a mixed effects logistic regression with a random intercept to predict the odds of being a frequent user in children from different sociodemographic groups.ResultsOne in 11 children (9.1%) who attended an ED attended four times or more in a year. Infants had a greater likelihood of being a frequent attender (OR 3.24, 95% CI 3.19 to 3.30 vs 5 to 9 years old). Children from more deprived areas had a greater likelihood of being a frequent attender (OR 1.57, 95% CI 1.54 to 1.59 vs least deprived). Boys had a slightly greater likelihood than girls (OR 1.05, 95% CI 1.04 to 1.06). Children of Asian and mixed ethnic groups were more likely to be frequent users than those from white ethnic groups, while children from black and 'other' had a lower likelihood (OR 1.03, 95% CI 1.01 to 1.05; OR 1.04, 95% CI 1.01 to 1.06; OR 0.88, 95% CI 0.86 to 0.90; OR 0.90, 95% CI 0.87 to 0.92, respectively).ConclusionOne in 11 children was a frequent attender. Interventions for reducing paediatric frequent attendance need to target infants and families living in deprived areas.

Design Capture

Abstract One of Allen-Bradley’s goals is leveraging — taking better advantage of existing resources. We are developing a methodology and supporting tools that help engineers share and reuse (i.e., leverage) their firmware design and development work. Writing reusable firmware source code is especially difficult due to the tight constraints in most embedded systems — code must usually be written for product specific hardware needs and resources. Reuse of engineering work at the design level is a more effective approach. With this in mind, we have been working with Allen-Bradley Power Products engineers and managers to pilot a Firmware Design Capture (FDC) system. In a FDC system, engineers work in their own paper or electronic workbooks compiling descriptions of their domains’ technologies and algorithms in loosely structured electronic document sets called technology books. Product-specific information is placed in complementary document sets called product books. Engineers can access this growing body of ‘Strategic Design Information’ that they and others have created; freely drawing from, commenting on, or adding to it. Key characteristics of this FDC system are: • A focus on collecting reusable and accessible design information • Incremental, small-grained development of documents during design activity • Electronic format of documents, for ease of refinement and access • Unobtrusive tools and methods, determined through frequent user feedback We expect this methodology to help engineers improve schedule predictability and reduce the firmware development life cycle, better retain vital technologies and product data, and increase product quality. Feedback from our initial work supports these expectations.

The project's main goal is to build an online book store where users can search for and buy books based on title, author, and subject. The chosen books are shown in a tabular style and the customer may buy them online using a credit card. Using this Website, the user may buy a book online rather than going to a bookshop and spending time. Many online bookstores, such as Powell's and Amazon, were created using HTML. We suggest creating a comparable website with .NET and SQL Server. An online book store is a web application that allows customers to purchase ebooks. Through a web browser the customers can search for a book by its title or author, later can add it to the shopping cart and finally purchase using a credit card transaction. The client may sign in using his login credentials, or new clients can simply open an account. Customers must submit their full name, contact details, and shipping address. The user may also provide a review of a book by rating it on a scale of one to five. The books are classified into different types depending on their subject matter, such as software, databases, English, and architecture. Customers can shop online at the Online Book Store Website using a web browser. A client may create an account, sign in, add things to his shopping basket, and buy the product using his credit card information. As opposed to a frequent user, the Administrator has more abilities. He has the ability to add, delete, and edit book details, book categories, and member information, as well as confirm a placed order. This application was created with PHP and web programming languages. The Online Book Store is built using the Master page, data sets, data grids, and user controls.

Optimization algorithms are a powerful tool for solving many problems of engineering applications from different fields of real life. They are usually used where the solution of a given problem analytically is unsuitable or unrealistic. If implemented in a suitable manner, there is no need for frequent user intervention into the actions of the equipment in which they are used. The majority of the problems of real life applications can be defined as optimization problems, for example, finding the optimum trajectory of a robot, optimal data flows in various processes like city traffic optimization or modelling and optimization of the seasonal variances of supply, traffic and facilities occupation in tourism among the others. The structure of this chapter is such that on the beginning are introduced bio-inspired algorithms, then parallelization of algorithms and parallel hardware and at the end, open research on Ho Chi Minh City traffic optimization real world example is introduced. In Conclusion are discussed possibilities of mutual combinations of introduced methods.

Users interact with the Internet in dynamic environments that require the IR system to be context aware. Modern IR systems take advantage of user location, browsing history or previous interaction patterns, but a significant number of contextual factors that impact the user information retrieval process are not yet available. Parameters like the emotional state of the user and user domain expertise affect the user experience significantly but are not understood by IR systems. This article presents results of a user study that simplifies the way context in IR and its role in the systems’ efficiency is perceived. The study supports the hypothesis that the number of user interaction contexts and the problems that a particular user is trying to solve is related to lifestyle. Therefore, the IR system’s perception of the interaction context can be reduced to a finite set of frequent user interactions.

Abstract The aim of the paper is to identify and categorize frequent patterns describing interactions between users in social networks. We analyze a social network with relationships between users that evolve in time already identified. In our research, we discover patterns based on frequent interactions between groups of users. The patterns are described by the characteristics of these interactions, such as their reciprocity, or the relative difference between estimations of global influences of the users participating in the discussions. The modification of the apriori algorithms is applied as one of the methods for pattern identification. The analyzed social network is built using the data set containing data from the Polish blog website salon24, which concerns mostly socio-political issues.

During the last few years, the EOS distributed storage system at CERN has seen a steady increase in use, both in terms of traffic volume as well as sheer amount of stored data. This has brought the unwelcome side effect of stretching the EOS software stack to its design constraints, resulting in frequent user-facing issues and occasional downtime of critical services. In this paper, we discuss the challenges of adapting the software to meet the increasing demands, while at the same time preserving functionality without breaking existing features or introducing new bugs. We document our efforts in modernizing and stabilizing the codebase, through the refactoring of legacy code, introduction of widespread unit testing, as well as leveraging Kubernetes to build a comprehensive test orchestration framework capable of stressing every aspect of an EOS installation, with the goal of discovering bottlenecks and instabilities before they reach production.

University makerspaces are growing increasingly in vogue, especially in Colleges of Engineering, but there is little empirical evidence in the literature that these spaces impact the students. Speculations have been made about these spaces creating a community of practice, improving retention, improving design skills and self-efficacy, teaching manufacturing skills, improving creativity, and providing many other benefits, but this has not been empirically documented. This paper compares student engineering design self-efficacy (i.e., confidence, motivation, expectation of success, and anxiety toward conducting engineering design) to reported usage rates from a makerspace at a large Hispanic-serving university in the Southwestern United States. Not all users of these spaces were engineering students, and as such, responses were examined through the context of student major as well as differences in gender, race/ethnicity, or first-generation college student status. Design self-efficacy is critical because when individuals have high self-efficacy for particular skills they tend to seek more opportunities to apply those skills, and show more perseverance in the face of set-backs. Thus, self-efficacy is often a good predictor of achievement. The results from one year of data at the Hispanic-serving university indicate that female and first-generation college students have significantly lower engineering design self-efficacy scores. The data also shows that being a user of the makerspace correlates to a higher confidence, motivation, and expectation of success toward engineering design. Initial data from two additional schools are also consistent with these same results. These results indicate that, for all students, regardless of race/ethnicity and/or first generation status, being a frequent user of a university-serving makerspace likely positively impacts confidence, motivation, and expectation of success toward engineering design.

Räumliche Verteilung

Zusammenfassung Hintergrund Obdachlose stellen eine besonders vulnerable Gruppe dar. Mit Obdachlosigkeit gehen viele zusätzliche Risiken einher, die auch Auswirkungen auf die Gesundheit haben. Viele Obdachlose suchen vermehrt Notaufnahmen auf. Eine Rolle spielt hier insbesondere die Kombination aus einer Abhängigkeitserkrankung mit einem psychischen Leiden. Methodik Die Arbeit untersucht das Vorkommen und die Eigenschaften von obdachlosen Frequent Usern im Rettungsdienst. Weiterhin wird die räumliche Verteilung betrachtet. Es wurde ein Zeitraum von einem Jahr anhand der Daten des Einsatzleitsystems betrachtet und ausgewertet. Ergebnisse In einem Zeitraum von 12 Monaten wurden 131 obdachlose Patienten als High Frequent User (7 – 10 Einsätze/Jahr) und Super Frequent User (≥ 11 Einsätze/Jahr) identifiziert, wobei der Anteil an Super Frequent Usern überwiegt. Insgesamt wurden durch diese 2021 Einsätze verursacht. Die Patienten waren im Durchschnitt 45,6 Jahre alt und zu 81% männlichen Geschlechts. Alarmierungen erfolgten insbesondere zum Stichwort „Intoxikation“ oder zum „Psychiatrischen Notfall“. Zu Einsätzen kam es wiederholt an bestimmten „Hot Spots“, es konnte gezeigt werden, dass sich Einsätze insbesondere in bestimmten lebensweltlich orientierten Räumen (LOR) konzentrieren. Diskussion Einsätze in Zusammenhang mit obdachlosen Frequent Usern sind zahlenmäßig durchaus relevant. Obwohl es verschiedene aufsuchende Systeme, insbesondere durch Wohlfahrtsverbände, zur medizinischen Versorgung gibt, scheinen sie diese Patientengruppe nicht zu erreichen. Eine Anbindung aufsuchender Sozialarbeit an die Notfallrettung, wie bereits in anderen Ländern erprobt, könnte insbesondere im Bereich von „Hot Spots“ zu einer Reduktion der Einsätze beitragen.

LEO constellation has received intensive research attention in the field of satellite communication. The existing centralized authentication protocols traditionally used for MEO/GEO satellite networks cannot accommodate LEO satellites with frequent user connection switching. This paper proposes a fast and efficient access verification protocol named BAVP by combining identity-based encryption and blockchain technology. Two different key management schemes with IBE and blockchain, respectively, are investigated, which further enhance the authentication reliability and efficiency in LEO constellation. Experiments on OPNET simulation platform evaluate and demonstrate the effectiveness, reliability, and fast-switching efficiency of the proposed protocol. For LEO networks, BAVP surpasses the well-known existing solutions with significant advantages in both performance and scalability which are supported by theoretical analysis and simulation results.
