<b><i>Background:</i></b> Contactless symptom tracking is essential for the diagnosis of COVID-19 cases that need hospitalization. Indications from sensors and user descriptions have to be combined in order to make the right decisions. <b><i>Methods:</i></b> The proposed multipurpose platform Coronario combines sensory information from different sources for a valid diagnosis following a dynamically adaptable protocol. The information exchanged can also be exploited for the advancement of research on COVID-19. The platform consists of mobile and desktop applications, sensor infrastructure, and cloud services. It may be used by patients in pre- and post-hospitalization stages, vulnerable populations, medical practitioners, and researchers. <b><i>Results:</i></b> The supported audio processing is used to demonstrate how the Coronario platform can assist research on the nature of COVID-19. Cough sounds are classified as a case study, with 90% accuracy. <b><i>Discussion/Conclusions:</i></b> The dynamic adaptation to new medical protocols is one of the main advantages of the developed platform, making it particularly useful for several target groups of patients that require different screening methods. A medical protocol determines the structure of the questionnaires, the medical sensor sampling strategy and, the alert rules.

Effective planning, coordination, and scheduling of the maintenance function can be, and for many years was, accomplished without computer support. However, in these days of high technology and rapid, economical data communication, job preparation is accomplished far more efficiently with the support of a sound maintenance management information system. Fast, flexible access to reliable, current, and comprehensive information is vital if planners and managers are to control the maintenance function on the basis of knowledge rather than intuition. The paper presents a maintenance information management system designed for the needs of the healthcare company. Due to its universality, the system can read information from different sources, appropriately process, interpret and deliver it to the right people in the most appropriate manner.

Having the right information at the right time is crucial to make decisions during emergency response. To fulfill this requirement, emergency management systems must provide emergency managers with knowledge management and visualization tools. The goal is twofold: on one hand, to organize knowledge coming from different sources, mainly the emergency response plans (the formal knowledge) and the information extracted from the emergency development (the contextual knowledge), and on the other hand, to enable effective access to information. Formal and contextual knowledge sets are mostly disjoint; however, there are cases in which a formal knowledge piece may be updated with some contextual information, constituting composite knowledge. In this paper, the authors extend a knowledge framework with the notion of composite knowledge, and use spatial hypertext to visualize this type of knowledge. The authors illustrate the proposal with a case study on accessing to information during an emergency response in an underground transportation system.

Hierarchy Process

Cloud computing is a significant paradigm shift in information technology (IT) service offerings that has been receiving enormous attention in academic and IT industry. Recent years has seen exponential growth in cloud use adoption, where many organizations are moving their IT resources into cloud due to flexibility and low-cost. However, on account of rapid innovation and growth in cloud technologies and service providers, selecting the right cloud services, provider and strategy is becoming increasing a common challenge to organization during cloud adoption. In an attempt to address this challenge, we propose application of Delphi Analytic Hierarchy Process (DAHP) method in selecting cloud deployment model. There are several cloud deployment models and organizations must identify the right model that best suits their business needs. The proposed approach facilitates a collaborative decision making process, consisting a number of decision makers whom, with consensus facilitated by the DAHP process, identifies feasible approaches, decision making factors and ultimate selection of a cloud deployment model alternative that is based on organizational business needs and capabilities. The DAHP process is illustrated by a means of a case study. The DAHP result analysis, as was illustrated in the case study, helps in explaining and justifying the choice selected as the best cloud deployment model.

Although a lot of information is available worldwide, getting the right piece of information is challenging. In addition, integrating information from different sources is still very complicated. To make the different information systems to interoperate, it is necessary to provide common knowledge structures. Ontologies have been developed for making the semantics of a domain explicit. However, using such formal structures is not straightforward and their benefits are not clear to the users. The work presented in this paper explores the use of an ontology for musical sound recordings in order to allow cataloguing and searching for such information. Therefore it investigates how the knowledge society can benefit from ontologies, with focus on the culture, more specifically the music domain. Some possible benefits and pitfalls are also described and a case study shows an evaluation of the proposed approach by users of this domain.

Phenomenological Case Study

Researchers have found that the majority of older individuals want to remain in their own home as they age. However, respecting the right of older individuals to exert control over their life while ensuring their safety can be a difficult undertaking to achieve. The aim of this research was to understand the lived experiences of an older couple who are in cognitive decline but are trying to maintain personal agency. The issue was studied using Bandura’s agency and self-efficacy theories as the theoretical framework. A phenomenological case study methodology was used. Participants were selected using a purposeful sampling strategy, and the sample was four individuals (father, mother, daughter, and grandson) from one family living at two separate residences. Data were collected using a mixed-methods approach. Qualitative data were collected by interviewing participants, and quantitative data were collected by administering a standardized cognitive assessment to the older individuals. Results indicated that the older couple were able to live independently because of the presence of the following five components: (a) adequate physical health; (b) adequate cognition, especially in the areas of memory and problem solving; (c) self-efficacy beliefs; (d) coping strategies to compensate for the declines in physical health and cognition due to aging; and (e) a support system to help the couple with activities they could no longer do on their own. In this study, each of the older individuals believed they could take care of themselves and wanted to live on their own. Independent living was only possible with significant assistance from family members.
