This article aimed to develop a mobile application for the management of coronavirus disease 2019 (COVID-19). We analyzed the pilot version with satisfaction through a survey and an interview with health workers from Sidi Said, a local hospital located in Mekn es, Morocco, which receives patients suffering from COVID-19. Methods: We have formed a team effort that involves health professionals, specialists from various fields and who participated in the design process of this project. It is a review of the existing literature and interviews with health professionals seeking to trace all the functions of this application. The user interface graphics, whether at the hospital or patient application level, were reviewed for effective usability by a multidisciplinary team. After having had to develop the pilot version of the application, the usefulness and the gratitude of the application were evaluated by eight patients and carers by means of a utility test, based on a real scenario, a utility survey. The objective is to ensure communication between the mobile application and the decision support application at the emergency services level to facilitate the detection of people who had developed COVID-19 as well as follow-up at home for detected patients. Results: The COVID-19 mobile management application provides capture functions and can afford information that helps in the prescription of appropriate drugs to patients at home. It is used to identify people who have been in contact with people who have tested positive for COVID-19, to carry out a large-scale screening by sending alert messages to these people, and to follow up via geolocation. There is also the possibility via Bluetooth, for the monitoring of patients without the activation of the Geolocation option. The approach adopted aims to reduce congestion in hospitals by identifying people suffering from respiratory illnesses or who may be contaminated, and monitoring them remotely. We offered six functions to achieve the objective of this project. Main: Respiratory crisis journal, medication recall, appointment, survey of people contacted, personal equipment and dashboard, daily traceability and monitoring, and geolocation. We have integrated the application of the electronic healthcare registration system in hospitals. To simplify usability, the frequently used functions, which are relatively important, can be found on the main page under the heading "COVID-19 monitoring" (in French: COVID-19 monitoring), and "Medication log" (in French: Journal medication). In addition, during graphic design, art therapy was used to improve the psychological stability of the patient. Eight participants were employed for the evaluation. For scenario-based tasks, out of ten tasks, all participants can record the entries in detail. The system use scale score was ß IEEE 2020.

PurposeAccording to United Nations reports, the worldwide population is expected to reach around 9.6 billion by 2050. This forecasting emphasizes the role of phosphate-based fertilizers for developing sustainable agriculture and ensures the demand all over the planet. From this perspective, phosphate companies are racing to improve their industrial performance and guarantee the quality, reliability and integrity of information efficiently. The purpose of this paper is to propose a traceability system framework that ensures product quality tracing and real-time operations monitoring for open-pit mines.Design/methodology/approachThe authors develop a hybrid approach that integrates Business Process Model and Notation techniques with System Modeling Language to formalize several use cases and scenarios to model quality traceability processes related to open-pit mines. This framework also embeds an optimization module based on mathematical modeling approaches to optimize stockpiles’ movement and respect the distinction between different qualities.FindingsThis paper explains a successful implementation of a quality traceability tool for an African mining company. The research team was able to understand and scale down the problem faced by the managers. Further, the study is focused on improving quality tracing over time and automatizing the current compliance processes related to the mine extraction activities. The proposed tool is proved highly effective in reducing the time of tracing quality claims by 46% compared with the manual procedure. Second, the implementation of this tool reduced fuel costs by 34% and CO2 emissions by 10%.Originality/valueThe originality of the contributions lies in four aspects: (1) adapting quality traceability concept for the mining industry; (2) assessing the current trends of traceability systems considering the mining industry context; (3) hybridizing business processes re-engineering, quality system and optimization modeling; and (4) using a real case study of a phosphate company to evaluate the framework.
