Abstract
The security of systems and networks is a multidisciplinary challenge of increasingly importance which has stimulated the development of multiple solutions for an effective response to the requirements that are needed. In pursuing this demand much of the focus of security proposals has focused on ensuring mechanisms that prevent organizations from being attacked from outside their perimeter. However, the evolution of the tasks carried out by the internal organizations collaborators, which demand an increasing degree of use of computational resources and privileged access to multiple sources of information, emerge an increasing concern in the monitoring of the behaviours of the users. In addition to this problem, there is often an ill-defined borderline confusion over what internal workers should be able to do with the resources they have in organizations. The mix between strictly professional use and personal use can be problematic in organization's security context. Define organizations security policies, understand user' behaviours, act effectively over security incidents and promote users' organizational security culture, by a pedagogical approach seems to us to be a necessary advance in security frameworks nowadays. This paper presents a reflection on the aspects of internal security of Local Area Networks and proposes a conceptual security framework, which aims to contribute to an effective control and understanding of LANs user' behaviour, to a real-time response to unwanted occurrences but, especially, to a pedagogical approach to help the development of users' security culture.

Abstract
Promoting Heritage is a challenge for all generations. The heritage is a legacy that we inherit from our ancestors and that we should deliver to our decedents. In this sense, the first steep that we should take, after preserve the heritage, is to develop solutions that enable effective and democratic ways to promote it. This promotion starts with the ability that of those who visit this heritage be able to know and enjoy it. Information and Communication Technologies and specifically Pervasive and Mobile Computing represents nowadays a big opportunity to develop innovative solutions capable to inform tourists about heritage and even enable them to experience past realities related to immaterial heritage like ancestral legends, past events and even no longer existing physical patrimony. This paper starts to make a reflection and the evolution the Information and Communication Technologies role on tourism and present a technological architecture to respond to the challenge of promote heritage and inform tourist in their travel experiences. After that, the paper presents also a developed prototype created to the Portuguese City of Mirandela capable to promote its historical and gastronomic heritage and also support the tours of the tourists through its territory. Finally, there are made some remarks about the future growing and directions for technology applied to tourism.

Abstract
Tuberculosis is one of the major public health concerns. This highly contagious disease affects more than 10.4 million people, being a leading cause of morbidity by infection. Tuberculosis is diagnosed at the point-of-care by the Ziehl-Neelsen sputum smear microscopy test. Ziehl-Neelsen is laborious, prone to human error and infection risk, with a limit of detection of 10(4) cells/mL. In resource-poor nations, a more practical test, with lower detection limit, is paramount. This work uses a magnetoresistive biosensor to detect BCG bacteria for tuberculosis diagnosis. Herein we report: i) nanoparticle assembly method and specificity for tuberculosis detection; ii) demonstration of proportionality between BCG cell concentration and magnetoresistive voltage signal; application of multiplicative signal correction for systematic effects removal; iv) investigation of calibration effectiveness using chemometrics methods; and v) comparison with state-of-the-art point-of-care tuberculosis biosensors. Results present a clear correspondence between voltage signal and cell concentration. Multiplicative signal correction removes baseline shifts within and between biochip sensors, allowing accurate and precise voltage signal between different biochips. The corrected signal was used for multivariate regression models, which significantly decreased the calibration standard error from 0.50 to 0.03 log(10) (cells/mL). Results show that Ziehl-Neelsen detection limits and below are achievable with the magnetoresistive biochip, when pre-processing and chemometrics are used.

Abstract
This paper presents the positioning, navigation and awareness (PNA) system developed for the Underwater Robotic Mining System of the VAMOS! project [1]. It describes the main components of the VAMOS! system, the PNA sensors in each of those components, the global architecture of the PNA system, and its main subsystems: Position and Navigation, Real-time Mine Modeling, 3D Virtual reality HMI and Real-time grade system. General results and lessons learn during the first mining field trial in Lee Moor, Devon, UK during the months of September and October 2017 are presented.

Abstract
This paper presents one methodology for teaching engineering students, which relies on open platform requiring basic knowledge of robotics, like mechanics, control or energy management. Walking robots are well known for being able to walk over rough terrain and adapt to various environments. Hexapod robots are chosen because of their better stability and higher number of different gaits. However, having to hold the whole weight of the body and a large number of actuators makes all walking robots less energetically efficient than wheeled robots. This platform endows students with an intuitive learning for current technologies, development and testing of new algorithms in the area of mobile robotics and also in generating good team-building. © 2019, Springer Nature Switzerland AG.
