This paper proposes a novel computational model that allows the dynamic adaptation of the information to be presented to the user in the frame of a web application. In adaptive web-based hypermedia systems, content and presentation are usually dealt with independently and sequentially, generating content first and then adapting its presentation. By contrast, our approach is based on the idea that it is impossible to select the best content and the best presentation independently, but effective user-system interaction can only be achieved through a joint assessment of content characteristics and presentation alternatives. Consequently, the goal of the approach is to determine the best match between a set of contents eligible to be presented to the user and a collection of possible presentations. To this end, the quality of a match is assessed on the basis of a set of user interface design principles focused on the relations existing between content and presentation. These principles express different and often contrasting exigencies and are generally articulated in vague and merely qualitative terms. In our approach they are formalized as soft constraints to be satisfied to the highest possible degree. A fuzzy approach is adopted to compute the degree to which a match satisfies each principle and to aggregate the results of the application of a set of interface design principles to a match. The proposed approach is substantiated through a running example in the area of e-commerce.

Recently, the Web-based learning (WBL) platform, particularly for higher education, has become more crucial due to the Covid-19 pandemic. Thus, due to the increased use of WBL   in higher education, an effective WBL interface design for higher education is truly important in order to attract students to use WBL and to further keep them engaged during learning via the Web-based platform. Therefore, the aim of this study was to determine the aesthetics of web interfaces based on experts’ opinions. This study adopted a quantitative research approach involving a data-gathering survey. Fifteen (15) WBL interfaces were designed based on nine (9) design principles which were balance, proportion, simplicity, alignment, movement, hierarchy, consistency, contrast, and proximity. The results of this study discovered that nine (9) WBL interfaces were determined by the experts as aesthetic interfaces, five (5) WBL interfaces as non-aesthetic and 1 (one) WBL interface was considered neither aesthetic nor non-aesthetic. This finding revealed that six (6) out of nine (9) interfaces had the balance design principle. However, balance was also in most non-aesthetic interfaces. A possible reason that balance was the most design principle in both the aesthetic and the non-aesthetic interfaces is that when designing WBL interfaces, there is a need to consider the combination of the design principles as a whole, and not count the design principles individually. In conclusion, this study's findings could contribute to the knowledge in the Human Computer Interaction domain, specifically in the interface design area.

Information professionals have observed that Web-based search interfaces simplify database searching and are preferred over other interfaces. A further anecdotal observation is that their features, in comparison to other interfaces, enhance the quality of search sessions, resulting in better outcomes. One explanation is that Web interfaces ease the negative emotive forces searchers experience with other interfaces. This paper examines the challenges in designing a research method to test the validity of these assumptions and observations. Although Web interfaces may provide a more supportive search setting, particularly for less experienced searchers, there is no evidence they contribute to better search outcomes.

Purpose: Use of genomic sequencing is increasing at a pace that requires technological solutions to effectively meet the needs of a growing patient population. We developed GUÍA, a web-based application, to enhance the delivery of genomic results and related clinical information to patients and families. Methods: GUÍA development occurred in 5 phases: formative research, content development, user interface design, stakeholder/community member input, and web application development. Development was informed by qualitative research involving parents (N=22) whose children underwent genomic testing. Participants enrolled in the NYCKidSeq pilot study (N=18) completed structured feedback interviews post-result disclosure using GUÍA. Genetic specialists, researchers, patients, and community stakeholders provided their perspectives on GUÍA's design to ensure technical, cultural, and literacy appropriateness. Results: NYCKidSeq participants responded positively to the use of GUÍA to deliver their children's results. All participants (N=10) with previous experience with genetic testing felt GUÍA improved result disclosure, and 17 (94%) participants said the content was clear. Conclusions: GUÍA communicates complex genomic information in an understandable and personalized manner. Initial piloting demonstrated GUÍA's utility for families enrolled NYCKidSeq pilot study. Findings from the NYCKidSeq clinical trial will provide insight into GUÍA's effectiveness in communicating results among diverse, multilingual populations.

Asynchronous telemedicine systems face many challenges related to information security as the patient's sensitive information and data on medicine dosage is transmitted over a network when monitoring patients and controlling asynchronous telemedical IoT devices. This information may be modified or spied on by a malicious adversary. To make asynchronous telemedicine systems more secure, the authors present a proxy-based solution against data modification and spying attacks in web-based telemedical applications. By obfuscating the executable code of a web application and by continuously dynamically changing obfuscation, the authors' solution makes it more difficult for a piece of malware to attack its target. They use a constructive research approach. They characterize the threat and present an outline of a proposed solution. The benefits and limitations of the proposed solution are discussed. Cyber-attacks targeted at the information related to patient's care are a serious threat in today's telemedicine. If disregarded, these attacks have negative implications on patient safety and quality of care.

<p>The joint ESA/JAXA BepiColombo mission to Mercury comprises two orbiters and a solar-electric transfer module, currently in a stack configuration. The BepiColombo spacecraft stack flew by the Earth on 10th April 2020 and will perform eight flybys more on its way to Mercury: two at Venus (in October 2020 and August 2021), and 6 at Mercury, starting from October 2021, before orbit insertion in December 2025. The two spacecraft host many instruments designed to study Mercury's interior structure, surface properties, close space environment, and their interplay.</p> <p>Processing the telemetry received from the spacecraft on ground into science products for the archive and providing quick access and visibility of the science results to the science team are the responsibility of the ESA Science Ground Segment (SGS). Raw and calibrated science products are generated by the data processing pipelines within hours after reception of the telemetry and can be visualised through a Quick-Look Analysis (QLA) web-application. Science products are also made available in the Planetary Science Archive (PSA) to the instrument teams for detailed analysis and further processing.</p> <p>This contribution will describe how the SGS data processing and quick-look analysis infrastructure, in operation since launch, has been enhanced to support the monitoring, sharing and analysis of all the scientific measurements that will be acquired during the flybys. This infrastructure includes instrument-specific calibration and reduction processing pipelines developed by the PI teams. Reduction pipelines are hosted either by the SGS or by the corresponding PI team based in a prime-redundant configuration and with a replica always available at the SGS.</p> <p>The Quick-Look Analysis web-application is intended to provide rapid feedback on the content and quality of the science archive products, to support the diagnosis of pipeline or instrument issues, to facilitate the monitoring of deviations of the executed observations from the planned observations and, when possible, to feedback the result of the analysis into the different cycles of the science planning. This strategy is science-driven and offers the possibility of exploring and sharing information and plots of the science data collected by both the MPO and MMO instruments among the BepiColombo science working team members.</p> <p>In addition to the Quick-Look Analysis web-application, all the spacecraft and payload housekeeping parameters are made available to the science team via a web-based user interface (WebMUST). This interface allows monitoring of the spacecraft and instrument operations in near-real time, as the telemetry arrives on ground. Pre-configured dashboards can be designed for specific needs such as monitoring the data volumes in the packet stores of the on-board mass memory (SSMM) along with the switch on of the various instruments of the BepiColombo payload.</p> <p>Despite the limited science capabilities of the spacecraft in cruise configuration (as the boresight of many instruments is partially or fully blocked by the Mercury Transfer Module), several instruments will perform calibration and scientific measurements during flybys. Some examples of how the science observations can be monitored with the tools developed by the SGS will be presented. The main goal of these tools is to make available to the science team all the information relevant for the post-analysis of the executed observations and to capture and preserve this knowledge for the future users of the BepiColombo data in the scientific community.</p>

To address diverse interaction needs of heterogeneous users' groups, user interfaces must be flexible to accommodate for customization that are specific to each user profile. Although, existing web interfaces provide some flexibility, some problems still remain: a) manual adjustments carried out by end users are required for each web application; b) the flexibility provided by current web interfaces is insufficient to address diverse interaction needs of various users' profiles and c) few users are aware about such options to customize the presentation of web interfaces. To contribute to the customization of user interface according to the needs of diverse users, in this work we asses the suitability of a tool that customize web interfaces based on the needs and preferences of end users. UIFlex is a web-based browser plugin that enables users to define their interaction profile. In this task, users are supported by fifteen web-based design rules that were extracted from the literature and the knowledge of authorities. To customize the presentation of web interfaces, UIFlex relies on a set of rules defined for each individual user and "injects" JavaScript codes, Cascading Style Sheets (CSS) and in some cases HyperText Markup Language (HTML) codes in any page that follows W3C standards. UIFlex was evaluated by 104 users of diverse interaction profiles. The results obtained are promising and suggest that the solution improves the perception that the interactive system performs as desired by users.

e21609 Background: Chemotherapy-associated cognitive impairment (CACI) experienced during survivorship can dramatically impair quality of life, particularly among patients receiving treatment with curative intent. We construct a web-based tool to predict the risk of self-perceived CACI at 15 months post-chemotherapy initiation among early stage breast cancer patients, to facilitate screening and early intervention. Methods: We recruited patients receiving chemotherapy for early-stage breast cancer between 2011 and 2014. Subjective cognitive function was assessed using FACT-Cog before, during and at 15 months after initiating chemotherapy. Based on a previously established minimal clinically important difference, an 11-point reduction in FACT-Cog score relative to that at baseline was considered as clinically significant CACI. Factors evaluated as potential predictors of CACI included clinical, laboratory and demographic factors, behavioural symptom and quality of life assessments (EORTC-QLQ-C30). Logistic regression was used to construct a model predicting CACI. Validation was performed on an external cohort recruited between 2015 and 2016. Model discrimination and calibration were evaluated using the receiver operating curve (ROC) and Hosmer-Lemeshow goodness-of-fit, respectively. The model was implemented as a web-based tool. Results: A total of 131 patients were recruited for model development. The model consisted of baseline EORTC-QLQ-C30 fatigue subscale percentage [effect size (95% confidence interval), 5.0% (2.0% to 7.0%), p < 0.001] and the change in FACT-Cog score after 2 cycles of chemotherapy, relative to baseline [-4.0% (-7.0% to -1.0%), p = 0.007]. The model was validated on an external cohort of 33 patients, with an ROC of 0.60, Hosmer-Lemeshow goodness-of-fit statistic of 5.86 (p = 0.44), sensitivity of 57.1% and specificity of 76.9%. The web application is accessible at http://bit.ly/CognitiveRisk Conclusions: A web application to predict CACI risk has been developed and externally validated. The tool facilitates early screening for patients at high risk for CACI and allows timely interventions to prevent or minimize the impact of CACI during survivorship.

As traffic simulation software becomes more effective for realistically simulating and analyzing traffic dynamics and vehicle interactions on the mesoscopic and microscopic level, the management, dissemination, and collaborative visualization of traffic simulation results produced by individual transportation planners presents a significant challenge. Existing online content management systems have a very limited capability in allowing users to query specific traffic simulation scenarios and geospatially visualize simulation results through shareable and interactive web interfaces. This paper presents a web-based application for promoting the archiving, sharing, and visualization of large-scale traffic simulation outputs. The application is developed to enhance cyber-physical controls, communications, and public education for collaborative transportation planning. Unique features of the web application include: (a) allowing users to upload their new traffic simulation scenarios (parameters and outputs), as well as search existing scenarios using easily accessible interfaces; (b) optimizing simulation output files with heterogeneous data formats and projected coordinate systems for web-based storage and management using a scalable and searchable data/metadata standard; (c) standardizing user-uploaded simulation outputs using web interfaces and data processing libraries with parallel computing capacity; and (d) providing shareable web visual interfaces for visualizing the traffic flow and signal information stored in simulation outputs (e.g., regional traffic patterns and individual vehicle interactions) and visually comparing multiple simulation outputs both spatially and temporally. The paper presents the conceptual design and implementation of this application, and demonstrates the application’s performance for sharing, comparing, and visualizing simulation outputs from VISSIM and SUMO, two commonly used traffic simulation software programs.

The overall aim of this study is to determine the performance of selected web-based dynamic middleware systems that are used for designing and implementing dynamic web application systems. This is necessary in a world where more applications are moving to the web, and slow performance of such applications can discourage users, thereby reducing profit, and reduce programmers’ productivity and quality of applications due to slow testing and execution. Java Servlets, Java Server Pages (JSP), Microsoft Active Server Pages (ASP), and Personal Home Page (PHP) were used to perform some operations on the server, like retrieving all records from a database stored on the server. The time taken since the query is initiated from the browser, to the time the query result is displayed on the client browser were measured for each of the four middleware systems as an estimate for their performance. Records were increased in multiples of thousands to estimate scalability along with the performance. PHP proved to be more efficient and more scalable.
