- Accessibility in tourism: optimizing the tourism experience through social sustainability interpretationPublication . Liberato, Pedro; Liberato, Dália; Vieira, Ana; Mendes, Teresa; Barreira, Hugo; Rodrigues, CristinaAccessibility has become one of the main key issues in tourism today, as it determines the extent to which an individual can participate in the activities/experiences provided by the sector in each destination. It ensures that all products, services, and facilities will be developed for everyone to use and that all will benefit from them. This is reflected in the accessibility related to the absence of obstacles to the use of the tourism product still present in the infrastructures, public transport, information, technology, or communication services. The improvement in accessibility may ensure opportunities for access, safely and autonomously, to equipment, transport, spaces, and information, allowing most segments to participate in all activities of daily life in an independent, comfortable, safe, and without discrimination of any kind. This research establishes the objective of identifying the accessibility measures adopted in the cities of Braga and Guimarães, in the Northern Region of Portugal, through issues related to the specific training of employees, the use of new technologies as a competitive advantage, the concern with presenting information in various formats and the appropriate means of transport. For the collection and analysis of information, the qualitative method was selected, an exploratory descriptive study, based on semi-structured interviews conducted with the official responsible, stakeholders, interpreter guides, and associations of each tourist destination. The results show that, despite the improvements diagnosed in recent years, the regions still face some barriers. The measures frequently identified with the aim of optimizing accessibility in tourism destinations were specifically the use of access ramps (removable or definitive) and the introduction of adapted toilets.
- AIRDOC: Smart mobile application for individualized support and monitoring of respiratory function and sounds of patients with chronic osbtructive diseasePublication . Almeida, Rute; Amaral, Rita; Jácome, Cristina; Martinho, Diogo; Vieira-Marques, Pedro; Jacinto, Tiago; Ferreira, Ana; Almeida, Ana; Martins, Constantino; Pereira, Mariana; Pereira, Ana; Valente, José; Almeida, Rafael; Vieira, Ana; Amaral, Rita; Sá-Sousa, Ana; Gonçalves, Ivânia; Rodrigues, Pedro; Alves-Correia, Magna; Freitas, Alberto; Marreiros, GoretiCurrent tools for self-management of chronic obstructive respiratory diseases (CORD) are difficult to use, not individualized and requiring laborious analysis by health professionals, discouraging their use in healthcare. There is an opportunity for cost-effective and easy-to-disseminate advanced technological solutions directed to patients and attractive to different stakeholders. The strategy of AIRDOC is to develop and integrate self-monitoring and self-managing tools, making use of the smartphone's presence in everyday life. AIRDOC intends to innovate on: i) technologies for remote monitoring of respiratory function and computerized lung auscultation; ii) coaching solutions, integrating psychoeducation, gamification and disease management support systems; and iii) management of personal health data, focusing on security, privacy and interoperability. It is expected that AIRDOC results will contribute for the innovation in CORD healthcare, with increased patient involvement and empowerment while providing quality prospective information for better clinical decisions, allowing more efficient and sustainable healthcare delivery.
- Biofiltration of Air/Styrene and Air/Styrene/Acetone mixtures in a bubble column reactorPublication . Vieira, Ana; Brás, IsabelThe goal of this work was the treatment of polluted waste gases in a bubble column reactor (BCR), in order to determinate the maximum value of reactor’s efficiency (RE), varying the inlet concentration (C in) of the pollutants. The gaseous mixtures studied were: (i) air with styrene and (ii) air with styrene and acetone. The liquid phase used to contain the biomass in the reactor was a basal salt medium (BSM), fundamental for the microorganisms’ development. The reactor used in this project consists of a glass column of 620mm height and inside diameter 75mm. In all essays there were continually measured: pH, dissolved oxygen and liquid’s temperature. Temperature and pH were controlled (T=24ºC, 7.0 ≤ pH ≤ 7.7). In all experiments the liquid volume (including the biomass) used in the reactor was kept constant (1.5L) as well as the total gas flowrate (1 L/min). Concerning the goal of the work, some parameters were calculated: the organic load (OL), removal efficiency (RE), elimination capacity (EC), biomass concentration (xf) and dry biomass concentration (Xdw). In a first series of experiments, the gas mixture used was air with styrene, varying its concentration from 191 mg.m-3 to 6500 mg.m-3.It was concluded that the RE maximum value (97%) was obtained for C in Sty = 4200 mg.m-3. For the maximum tested value of C in Sty, RE obtained was 20%. In a second step, the gaseous mixture included acetone, varying C in Sty between 225 mg.m-3 and 2659 mg.m-3 and C in Ac between 153mg.m-3 and 1389 mg.m-3. The aim of these tests was the determination of C in Ac for which RE was maximum, obtaining C in Ac = 750 mg.m-3. A third series of experiments was performed, in which C in Ac was maintained equal to that value and C in Sty was varied until higher values (5422 mg.m-3). RE maximum values obtained in this last series were 100% for styrene and 40% for acetone. One important conclusion is the fact that the microorganisms available degrade better styrene than acetone. On the ambit of this study, it was possible to identify the species available in biomass: Xanthobacter antotrophicus py2, Enterobacter aerogenes, Nocardia, Corynebacterium Spp., Rhodococcus rhodochrous e Pseudomonas Sp.
- Improving accessibility as a strategy for social sustainability in tourism supplyPublication . Liberato, Dália; Liberato, Pedro; Vieira, Ana; Rodrigues, Cristina; Mendes, TeresaTourism is a citizens’ right. Therefore, all of society has the right to enjoy tourism experiences regardless of individual preferences. The increase in the elderly population (+ 65 years), the high number of people with disabilities (physical, hearing, intellectual, and cognitive) in the world and the growing desire to travel, has accelerated the interest and concern for accessibility, to provide a better experience to these tourists, increasing practices and strategies under the “Accessible and Inclusive Tourism.” However, this tourism segment still has a long way to go, since many barriers persist. The present research aims to analyze accessibility in cultural heritage. For the collection and analysis of information, the qualitative method was selected, exploratory descriptive study, based on semi-structured interviews conducted with representatives of official entities, stakeholders, interpreter-guides, and associations of two medium-sized destinations in Northern Portugal (Braga and Guimarães), with the aim of assessing accessibility in the historical-cultural heritage in medium-sized cities of particular relevance. The city of Guimarães was distinguished as a World Heritage Site, being associated with the birth of Portugal as a nation, bringing an enormous relevance in terms of valorization and empowerment of its historical and cultural heritage by a segment that is increasingly more universal (accessible), having here the concern to evaluate urban policies in terms of accessibility to heritage and tourism destination. According to the typologies framed in Accessible Tourism, it is possible to highlight that, regarding the percentage of tourists with reduced mobility who visit tourism destinations, and, of these, which ones are interested in cultural heritage and what degree of satisfaction they express, the two tourism destinations analyzed do not account for this type of data, since it is a very residual public. Regarding other types of disabilities, some projects have been developed. Considering the definition of strategies to implement in the access to heritage, it is possible to evidence that, despite the improvements made by the destinations, the existing cultural heritage is not completely accessible, existing mainly architectural barriers. The results show that accessibility is being considered as a strategic opportunity for the targeted tourism destinations, however these are still partially accessible, and it is expected that the path to accessibility is a complex process and applicable in the medium to long term.
- Multidisciplinary development and initial validation of a clinical knowledge base on chronic respiratory diseases for mHealth decision support systemsPublication . Pereira, Ana Margarida; Jácome, Cristina; Jacinto, Tiago; Amaral, Rita; Pereira, Mariana; Sá-Sousa, Ana; Couto, Mariana; Vieira-Marques, Pedro; Martinho, Diogo; Vieira, Ana; Almeida, Ana; Martins, Constantino; Marreiros, Goreti; Freitas, Alberto; Almeida, Rute; Fonseca, João A.Most mobile health (mHealth) decision support systems currently available for chronic obstructive respiratory diseases (CORDs) are not supported by clinical evidence or lack clinical validation. The development of the knowledge base that will feed the clinical decision support system is a crucial step that involves the collection and systematization of clinical knowledge from relevant scientific sources and its representation in a human-understandable and computer-interpretable way. This work describes the development and initial validation of a clinical knowledge base that can be integrated into mHealth decision support systems developed for patients with CORDs. A multidisciplinary team of health care professionals with clinical experience in respiratory diseases, together with data science and IT professionals, defined a new framework that can be used in other evidence-based systems. The knowledge base development began with a thorough review of the relevant scientific sources (eg, disease guidelines) to identify the recommendations to be implemented in the decision support system based on a consensus process. Recommendations were selected according to predefined inclusion criteria: (1) applicable to individuals with CORDs or to prevent CORDs, (2) directed toward patient self-management, (3) targeting adults, and (4) within the scope of the knowledge domains and subdomains defined. Then, the selected recommendations were prioritized according to (1) a harmonized level of evidence (reconciled from different sources); (2) the scope of the source document (international was preferred); (3) the entity that issued the source document; (4) the operability of the recommendation; and (5) health care professionals’ perceptions of the relevance, potential impact, and reach of the recommendation. A total of 358 recommendations were selected. Next, the variables required to trigger those recommendations were defined (n=116) and operationalized into logical rules using Boolean logical operators (n=405). Finally, the knowledge base was implemented in an intelligent individualized coaching component and pretested with an asthma use case. Initial validation of the knowledge base was conducted internally using data from a population-based observational study of individuals with or without asthma or rhinitis. External validation of the appropriateness of the recommendations with the highest priority level was conducted independently by 4 physicians. In addition, a strategy for knowledge base updates, including an easy-to-use rules editor, was defined. Using this process, based on consensus and iterative improvement, we developed and conducted preliminary validation of a clinical knowledge base for CORDs that translates disease guidelines into personalized patient recommendations. The knowledge base can be used as part of mHealth decision support systems. This process could be replicated in other clinical areas.
