Abstract
Service design is a multidisciplinary field dedicated to create new and innovative services. To accomplish this goal, service design resorts to contributions from other disciplines such as service management, marketing, information systems and interaction design. However, service design lacks dedicated methods and models that integrate the contributions from these disciplines. Design science research (DSR) offers a solid methodology to develop such artifacts and is already starting to be used in service research. To show how DSR can support service design, this article presents two new service design methods that have been developed using DSR and examines the process followed for developing them. Building on these methods, the article discusses how DSR can leverage service design characteristics of multidisciplinarity, human-centeredness and creativity, to develop further knowledge contributions for service design. Finally, the challenges posed by using DSR in service design and service research are also discussed, as well as ways to address those challenges. © 2018, Springer Nature Switzerland AG.

Abstract
Aim: We investigated the demographic, anthropometric, clinical, biochemical and behavioural factors associated with children and adolescents who missed breakfast. Methods: This 2012 cross-sectional study was carried out in the city of Juiz de Fora, Brazil, with a sample of 684 students: 191 children aged 7-9 and 493 adolescents aged 10-14. Data on demographic, physical activity and breakfast consumption were based on a 24-hour recall record and a three-day dietary record. Weight, height, body fat, waist circumference and blood pressure were also measured. Finally, samples were collected for analysis of blood total cholesterol, low-density and high-density lipoproteins, triglycerides and glucose. The statistics are presented as prevalence ratios (PR) with 95% confidence (95% CI) intervals. Results: Missing breakfast was more common among adolescents than children (30% versus 22%) and among girls of all ages than among boys (33% versus 22%). It was also associated with children, but not adolescents, with increased levels of diastolic blood pressure (PR 5.6, 95% CI 1.8-17.4), total cholesterol (PR 1.5, 95% CI 1.2-1.9) and low-density lipoprotein (PR 2.1, 95% CI 1.5-2.9). Conclusion: Missing breakfast was more common among adolescents and females and associated with increased levels of diastolic blood pressure, total cholesterol and low-density lipoprotein in children.

Abstract
Kinematic analysis of human movement is very important in several areas, such as in sports (e.g., for athletic performance analysis), health (e.g., rehabilitation of people with motor disabilities) and others. The study of the kinematics of the human body involves several methods that resort to the analysis of several parameters that come from the movement. Important parameters to take into account are the acceleration, velocity and position (linear or angular) of the various articulations of the human body, which can be measured by sensors or through the analysis of repeated images obtained by camera. In this paper will be presented a suit that acquire the different position of human joints that will be useful in rehabilitation, FatoXtract. It is through the analysis of human movement that we can analyze whether the movement in rehabilitation is adequate or not.

Abstract
Aging of Tawny Port wine is a multifactorial process critical for attaining the desired quality. Real time monitoring of important intrinsic and extrinsic factors that are known to affect the time and quality of the aging process are important to optimize and to manage the natural variability between wines aged in different long used wood barrels. For this study, a distributed monitoring system was installed in sixteen oak barrels, placed in two adjacent wineries - one of them with controlled temperature in the Douro Demarcated Region, Portugal. The monitoring process was performed using a RS-485 industrial network, which interconnects sensors that continuously measure wine temperature, pH, redox potential and wine's dissolved oxygen, as well as other sensors that measure parameters related to the barrels' environmental context, such as room temperature and relative humidity. This work presents the design, development and implementation of a remote distributed system to monitor such parameters, aiming to determine the existence of behaviour models for Port Tawny wine during aging in long-used oak barrels, depending on their storage history and to understand the evolution of wine pH, dissolved oxygen and redox potential in real winery conditions as well as their dependence on the wine's storage temperature. This approach is based on easy-to-use embedded systems, with the aim of giving a relevant contribution to other projects in the area of precision enology.
