Abstract
Engineering education addresses the development of professional competencies in undergraduates. In this context, the core set of professional competencies includes critical thinking and problem solving, effective communication, collaboration and team building, and creativity and innovation-also known as the four Cs-as well as socio-professional ethics and sustainable development-referred in this paper as the two Ss. While the four Cs were identified by the associates of the American Management Association based on the needs of the society, professional associations, and businesses; this paper proposes the two S extension to ensure that future engineers contribute to the well-being of individuals and the preservation of life on Earth. It proposes a tangible framework-the 4C2S-and an application method to analyse the contributions made by engineering capstone programmes to the development of these core competencies in future engineering professionals. The method is applied to an engineering capstone programme-the European Project Semester (EPS) offered by the Instituto Superior de Engenharia do Porto (ISEP)-and a specific project case-EPS@ISEP Pet Tracker project developed in 2013, constituting, in addition, a road map for the application of the 4C2S framework to engineering capstone programmes. The results show that EPS@ISEP complies with the 4C2S framework.

Abstract
Background: Health Information Systems (HIS), and especially Electronic Health Records (EHR), offer great promise. However, the true benefits of HIS and EHR are more elusive as research shows they have obtained mixed results across countries. To increase the success of these systems while creating value for healthcare professionals, research emphasizes the importance of involving clinical users in the design of HIS. Objective: Following calls for interdisciplinary research and increased end-user participation in HIS development, this paper shows how a service design approach can support the successful development and implementation of national EHRs. Service design brings a human-centered, participatory, holistic, creative and visual approach to HIS development, through an iterative process of exploration, ideation, reflection and implementation, fostering stakeholder participation and co-creation of the solution. Method: This paper presents an in-depth case study of the Portuguese National EHR development and implementation following a service design approach. The study involved individual and group interviews, as well as participatory design workshops with more than 170 participants along the different stages of exploration, ideation, reflection and implementation. Results: The service design approach, including the visual models and tools used across the different design stages, was instrumental to envision new EHR concepts and design the system to enhance healthcare users experience. A qualitative study performed after implementation showed that the EHR was considered useful and easy to use, and these results are backed by widespread usage of the system. Discussion and conclusion: This paper shows how a service design approach can address key challenges in EHR development. By adopting a holistic perspective, service design broadens the scope of EHR development to understand its broader service system and position it to enable value creation with users. The human-centered, participatory, creative, visual and holistic approach supports the understanding of user needs and context, and their active involvement in the design and co-creation effort. This service design approach fosters user adoption at the implementation stage. Service design can thus contribute to the successful development and implementation of EHRs.

Abstract
In the Mediterranean region, water scarcity has already prompted concern in the wine sector due to the strong impact it has on vineyard productivity and wine quality. Water footprint is an indicator that takes account of all the water involved in the creation of a product and may help producers to identify hotspots, and reduce water consumption and the corresponding production costs. In recent years several studies have been reported on wine water footprint determination, but mostly focused on the viticulture phase or assuming no grey water footprint at the winery since it has a treatment system. In the framework of the WineWaterFootprint project a medium-size winery was monitored, with direct measurements, regarding determination of the blue and grey components of water footprint. The determined winery water footprint ranged from 9.6 to 12.7 L of water per wine bottle of 0.75 L, the wastewater produced being responsible for about 98%, which means that the grey component cannot be disregarded. The developed scenarios show that a potential reduction of 87% in winery water footprint can be obtained with almost no investment. The challenge of reducing the grey footprint is not in technology development, but rather in the proper maintenance and monitoring of treatment systems.

Abstract
Spreadsheets play a pivotal role in many organizations. They serve to store and manipulate data or forecasting, and they are often used to help in the decision process, thus directly impacting the success, or not, of organizations. As the research community already realized, spreadsheets tend to have the same problems “professional” software contain. Thus, in the past decade many software engineering techniques have been successfully proposed to aid spreadsheet developers and users. However, one of the most used mechanisms to manage software projects is still lacking in spreadsheets: a version control system. A version control system allows for collaborative development, while also allowing individual developers to explore different alternatives without compromising the main project. In this paper we present a version control system, named SheetGit, oriented for end-user programmers. It allows to graphically visualize the history of versions (including branches), to switch between different versions just by pointing and clicking, and to visualize the differences between any two versions in an animated way. To validate our approach/tool we performed an empirical evaluation which shows evidence that SheetGit can aid users when compared to other tools.

Abstract
This paper presents a novel radio localization system based on radio signal strength measurements to estimate the location of animals on a farm. The system uses low-cost mobile devices based on a microcontroller, a radio transceiver and an antenna. The developed solution works on the 433 MHz band and comprises innovative protocols that use the radio wake-up concept in order to minimize the mobile unit energy consumption, promoting that way its autonomy. A software application was developed to track the animals on a real-time basis using the Internet of Things paradigm. © 2019 IEEE.

Abstract
Esophageal cancer is a disease with a high prevalence that can be evaluated by a variety of imaging modalities, including endoscopy, computed tomography, and positron emission tomography. Computer-aided techniques could provide a valuable help in the analysis of these images, decreasing the medical workflow time and human errors. The goal of this paper is to review the existing literature on the application of computer vision techniques in the domain of esophageal cancer. After an initial phase where a set of keywords was chosen, the selected terms were used to retrieve papers from four well-known databases: Web of Science, Scopus, PubMed, and Springer. The results were scanned by merging identical entries, and eliminating the out of scope works, resulting in 47 selected papers. These were organized according to the image modality. Major results were then summarized and compared, and main shortcomings were identified. It could be concluded that, even though the scientific community has already paid attention to the esophageal cancer problem, there are still several open issues. Two majorfindings of this review are the nonexistence of works on MRI data and the under-exploration of recent techniques using deep learning strategies, showing the need for further investigation.
