This paper discusses a new automated training system called CATS. The proposed system covers all the main components of the educational process, including the simple and convenient formation of educational material, tasks for laboratory works, tests to check knowledge, allows you to monitor the progress of students, the process of studying educational content, check completed work for plagiarism, send incorrectly completed tasks to correction, keep an electronic journal and much more. The automated CATS system has been introduced into the educational process at the Belarusian National Technical University and is actively used, especially in the context of the COVID-19 pandemic. In the spring of 2020 alone, more than a thousand users have registered in the CATS system. The intellectual component in the CATS system allows you to implement a unique training program, which is based on the existing knowledge and the level of perception of the educational material by the students. As mathematical methods, it is proposed to use the analysis of expert systems, as well as artificial neural networks. These mathematical methods made it possible to develop adaptability algorithms, their software implementation and testing in the educational process. Users are provided with a web application and its mobile clients for iOS and Android operating systems. Mobile applications are localized in Russian, Belarusian, English and German. By formalizing the intellectual processes that are carried out by both the teacher and the student, it is possible to automate a certain part of their functions, reduce the cost of manual labor, which will make it easier to control the educational process, and make the training itself more effective.

This chapter explains the design and execution of a pre-service teacher training case study using Augmented Reality (AR), Quick Response (QR) codes, and social media mobile applications installed on iPads. The ScavengAR Hunt activity centered on a story narrative inspired by works of fine art using trigger images from the AR mobile application ARART® and incorporated elements of the board game Clue®. Pre-service teachers in the study were divided into groups of 4-6 and assigned specific, individual roles related to a mobile application used in the ScavengAR Hunt, and completed specific tasks while exploring the campus of a midwestern university. The research monitored the groups in real-time through reports submitted on Twitter and responses from QR code scans. The ScavengAR Hunt served as a model for designing a mobile learning activity incorporating multiple mobile applications.

BACKGROUND Our institution has prioritized improving hand hygiene rates. Empty or broken alcohol-based hand sanitizer dispensers are a barrier to efficient hand hygiene practices. One barrier is the lack of modalities for employees to alert when a dispenser is empty or broken. OBJECTIVE We hypothesize that adding predefined QR code functionality to an existing web-based service repair application for staff will facilitate increased alerts about empty hand sanitizer dispensers. METHODS The FixIt app is a Web-based application that enables staff at our academic hospital to report issues to environmental services including when supplies are broken, if rooms are dirty, or if an item in a room needs to be restocked. However, users must type a free text description of the problem to report it. We propose adding functionality to allow users to scan a QR code with their SmartPhone or enter a unique text code that will be labeled on each hand sanitizer dispenser. This unique code will be directly associated to a specific dispenser and alert the environmental services department to the exact dispenser to fix or replace, thereby reducing the number of empty or broken dispensers. To measure the scope of the problem, we evaluated the functionality of all hand sanitizer dispensers in public spaces on patient wards and hallways in our institution at a single point in time and then sequentially over a course of 48 hours. We also evaluated the usage of the existing FixIt application and categorized the types of requests that FixIt has processed to date. RESULTS Out of 535 hand sanitizer dispensers, forty-nine dispensers (9.2%) were not functional on our baseline evaluation. After 12 hours, 23 of these non-functional dispensers (46.9%) had not yet been fixed or refilled. After 48 hours, 17 dispensers (34.7%) were still not functioning. The existing FixIt application without QR codes was deployed in September 2017. Since then, the application has generated over 400 FixIt requests via manual text-entry form. Of those requests, 17% were categorized as “repair/restock” requests. CONCLUSIONS We propose adding a QR-based feature to an existing Web-based application to streamline and facilitate repetitive tasks such as reporting empty or broken hand sanitizer dispensers. Our preliminary results suggest that users are already willing to utilize a manual form via a Web application to request restocking or repair of items within the hospital. We think that lowering the barrier for reporting by utilizing QR codes may improve usage rates of this feature. Our next steps are to implement a small pilot of the FixIt QR code evaluate uptake and utilization.

PurposeWeb applications are subject to continuous changes and rapid evolution triggered by increasing competition, especially in commercial domains such as electronic commerce. Unfortunately, usually they are implemented without producing any useful documentation for subsequent maintenance and evolution. Thereof, the maintenance of such systems becomes a challenging problem as the complexity of the web application grows. Reverse engineering has been heralded as one of the most promising technologies to support effective web application maintenance. This paper aims to present a reverse engineering approach that helps understanding existing undocumented web applications to be maintained or evolved.Design/methodology/approachThe proposed approach provides reverse engineering rules to generate a conceptual schema from a given domain ontology by using a set of transformation rules. The reverse engineering process consists of four phases: extracting useful information; identifying a set of ontological constructs representing the concepts of interest; enriching the identified set by additional constructs; and finally deriving a conceptual schema.FindingsThe advantage of using ontology for conceptual data modeling is the reusability of domain knowledge. As a result, the conceptual data model will be made faster, easier and with fewer errors than creating it in usual way. Designers can use the extracted conceptual schema to gain a better understanding of web applications and to assist in their maintenance.Originality/valueThe strong point of this approach is that it relies on a very rich semantic reference that is domain ontology. However, it is not possible to make a straightforward transformation of all elements from a domain ontology into a conceptual data model because ontology is semantically richer than data conceptual models.

Quick response (QR) codes are usually scanned in different environments, so they must be robust to variations in illumination, scale, coverage, and camera angles. Aesthetic QR codes improve the visual quality, but subtle changes in their appearance may cause scanning failure. In this article, a new method to generate scanning-robust aesthetic QR codes is proposed, which is based on a module-based scanning probability estimation model that can effectively balance the tradeoff between visual quality and scanning robustness. Our method locally adjusts the luminance of each module by estimating the probability of successful sampling. The approach adopts the hierarchical, coarse-to-fine strategy to enhance the visual quality of aesthetic QR codes, which sequentially generate the following three codes: a binary aesthetic QR code, a grayscale aesthetic QR code, and the final color aesthetic QR code. Our approach also can be used to create QR codes with different visual styles by adjusting some initialization parameters. User surveys and decoding experiments were adopted for evaluating our method compared with state-of-the-art algorithms, which indicates that the proposed approach has excellent performance in terms of both visual quality and scanning robustness.
