Abstract:
On information technology topics, the word “innovation” is increasingly present every day. Regarding the Internet of Things (IoT) subject, it’s no different. Every year new IoT products and services are created and presented that allow users to make their lives easier and simpler, connecting people to devices remotely and automatically, generating mobility and operability of services through the heterogeneity of devices connected to the internet. Based on obstacles found in daily homes, this paperwork aims study the development of a unique and easy use platform. On this platform, it is possible to have IoT devices centralized on the same local network unit so that they can be managed and manipulated through a simple and intuitive graphical interface. Thus, management is unified and practical for any type of user who is interested in using this technology. In this thesis, good practices and the best solutions researched within the practice of IoT management were studied in different scenarios. Covering types of technologies, proposed architectures, configuration processes and compatibility analysis of features and functionality of different devices currently on the market. Thus, this work aims to present in detail the study of the prototype of a unified platform that allows configuring, monitoring, and managing the integration between heterogeneous devices currently on the market for residential users

Abstract:
Financial technology (FinTech) has swiftly revolutionized mobile money as one of the ways of accessing financial services in developing countries. Numerous mobile money applications were developed to access mobile money services but are hindered by severe authentication security challenges, thus, forcing the researchers to design a secure multi-factor authentication (MFA) algorithm for mobile money applications. Three prototypes of native mobile money applications (G-MoMo applications) were developed to confirm that the algorithm provides high security and is feasible. This study, therefore, aimed to evaluate the usability of the G-MoMo applications using heuristic evaluation and usability testing to identify potential usability issues and provide recommendations for improvement. Heuristic evaluation and usability testing methods were used to evaluate the G-MoMo applications. The heuristic evaluation was carried out by five experts that used the 10 principles proposed by Jakob Nielsen with a five-point severity rating scale to identify the usability problems. While the usability testing was conducted with forty participants selected using a purposive sampling method to validate the usability of the G-MoMo applications by performing tasks and filling out the post-test questionnaire. Data collected were analyzed in RStudio software. Sixty-three usability issues were identified during heuristic evaluation, where 33 were minor and 30 were major. The most violated heuristic items were “help and documentation”, and “user control and freedom”, while the least violated heuristic items were “aesthetic and minimalist design” and “visibility of system status”. The usability testing findings revealed that the G-MoMo applications’ performance proved good in learnability, effectiveness, efficiency, memorability, and errors. It also provided user satisfaction, ease of use, aesthetics, usefulness, integration, and understandability. Therefore, it was highly recommended that the developers of G-MoMo applications fix the identified usability problems to make the applications more reliable and increase overall user satisfaction.

Abstract:
The gender and economic conditions of students from Higher Education Institutions attending the 1st year, after the COVID-19 pandemic, acquires great importance, especially in terms of study conditions and their emotions. The study, with an international scope and on two continents, aims to use the pandemic questionnaire for students (QEP), with five dimensions under study: conditions for study, emotions, academic performance, teaching strategies and sociability. The QEP was answered by 101 students from a private higher education institution in northern Portugal. The QEP questionnaire is part of a research project that aims to guide specific institutional policies to support students' permanence and completion of courses in Higher Education Institutions, allowing the early identification of intentions to drop out or students at risk. As well as to understand how e-learning teaching influenced teaching, learning and the permanence of students in higher education institutions.

Abstract:
This work analyzes the adoption of Enterprise Resource Planning (ERP) information systems in small and medium enterprises (SMEs). Adoption of ERP in SMEs can provide better control of organizational processes and quality to the information that drives decision-making. However, small and medium-sized enterprises have long remained outside the scope of ERP adoption research. Current scientific literature cover, at first, large firms and when SMEs are the unit of analysis, results are not similar whether compared to the large firms. Thus, this research aims to identify and analyze the factors that influence the adoption of ERP in SMEs. This purpose was achieved through a qualitative approach, inductive logic, interpretive epistemology, and a multiple case study (six firms) in companies located at the southern of Minas Gerais state, Brazil. Data were collected by interviews with the managers (administrative or IT) and analyzed by two techniques: Lexical and Content Analysis. We used Iramuteq software to support Lexical Analysis. We observed that the adoption of ERP in SMEs has higher influence by Technological and Organizational constructs than by Environmental factors. Variables such as commercial partnerships, external support and competitiveness were not observed as a factor that influence ERP adoption in SMEs. Otherwise, added value, compatibility, firm size, and the composition of the steering body were observed as a factor that positively influence ERP adoption in Brazilians SMEs.

Abstract:
Interaction and command modes as well as their combination are essential features of modern and futuristic robotic systems interacting with human beings in various dynamical environments. This paper presents a synthetic overview concerning the most command modes used in Human-Robot Interaction Systems (HRIS). It includes the first historical command modes which are namely tele-manipulation, off-line robot programming, and traditional elementary teaching by demonstration. It then introduces the most recent command modes which have been fostered later on by the use of artificial intelligence techniques implemented on more powerful computers. In this context, we will consider specifically the following modes: interactive programming based on the graphical-user-interfaces, voice-based, pointing-on-image-based, gesture-based, and finally brain-based commands.

Abstract:
Few industries were more affected by the COVID-19 pandemic than tourism. One of Europe´s leading tourist destinations, Porto had undergone a major tourism boom until the start of pandemic. Mobile Augmented Reality (MAR) is one of the many emerging technologies that has great potential for tourist operators. Using this technology, they can create innovative tourism products that will help them recover from the present crisis. As a result, in this study, we will empirically test the latest version of the Unified Theory of Acceptance and Use of Technology (UTAUT) model to explore the factor leading to the adoption Mobile Augmented Reality in Tourism (MART) in Porto. In doing so, we aim to contribute to growing literature on the topic of Mobile Augmented Reality (MAR). The originality of this study lies in the use of an extended UTAUT model with greater predictive power and the exploration of the moderative role of gender, age and experience. To the data obtained from a random sample of 201 respondents who voluntarily answered an anonymous online questionnaire, we applied structural equational modeling and partial least squares (SEM-PLS) analysis to test the model. Our findings show that habit, hedonic motivations and facilitating conditions are the determinants of the use of MART.

Abstract:
Even though software change is inevitable, accurate maintenance can extend software lifespan in a subtle way when both budget and time constraints get in the way of software replacement. In the University of Aveiro, the project PmatE – a quiz web platform created to encourage students to like Math – emerged in the early 1990’s and stacked several applications over the decades without major planning, cleaning or upgrade. This resulted in a huge-sized framework that was crucial to be always available and online and had high operational cost, leading to an increasing amount of technical debt. After 3 decades, the project was studied, refactored and refurbished, leading to a stable consistent framework ready for evolution and software spinouts. This work shows how to manage and engineer solutions to maintain a legacy system and evolve it even when tied up to heavy constraints.

Abstract:
There is a wide variety of content management systems (CMS) available on the market, each with its characteristics, advantages and disadvantages, but the open source, such as Joomla, WordPress and Drupal are the ones who stand out, not only because they are free, but also because of their versatility and contemporaneity, in issues such as: ease of use, possibility of customization, support, security, adaptability and amount of resources available (modules, components and plugins). These solutions have an extremely relevant aspect for public organizations, bringing citizens and businesses closer to their governments, by providing a more direct and intuitive access to government information and services (Fang, 2002). To achieve the benefits of its implementation, it is necessary an analysis of the solutions available on the market and which ones are best suited to certain management objectives. Through a comparison of data and information collected, it is highlighted the advantages and disadvantages of each of the three CMS mentioned, especially which one is most indicated for a specific context of application and project typology in public administration, using for these rankings of use and popularity on platforms such as W3Techs and BuiltWith, as well as a set of supporting documentation.

Abstract:
As a result of the increasing demand on the credibility of the financial information disclosure, internal auditing has been playing an increasingly important role in organizations. Currently, there is a need to ensure the compliance of organizational transactions in real time in order to increase the reliability of the information and to reduce risks. In this context, the concept of Continuous Assurance has emerged, allowing to reduce potential errors and risks and obtain useful information in real time, supporting more effectively the decision making and internal auditing. This paper aims to understand the importance and the use of Continuous Assurance services from the perspective of the internal auditor. So, the methodology used is qualitative and the questionnaire survey was used to collect data from interna auditors in Portugal. The main results demonstrate, among other findings, that the Continuous Assurance services are considered by the internal auditors as very important. Despite this, its implementation in the organizations does not follow the importance assigned to it, and is still far from being fully deployed. The dimension of the audit department is an influential factor in the use of some Continuous Assurance services.
