-Learning management systems and social networks on Web have been tools most used by students in higher education institutions as learning support tools outside of the classroom. In this paper, we present the results from a survey conducted at a Portuguese university to 159 students in Computer Science and Psychology about the purposes and reasons for the use of Moodle and Facebook. We conclude, among other conclusions, that they complement each other: while the first is mostly used for formal communication with teachers, the second is mostly used for informal communication with peers.

In this paper, we present a review on the use of ontologies in learning object repositories systems for searching and suggestion purposes, considering its adoption for the seaThings project that aims to promote the ocean literacy. We also describe the use case of the Cognix system and Agent-based Learning Objects -OBAA metadata standard for learning objects which is being implemented on a new learning objects repository. This system includes concepts from artificial intelligence such as agents and ontologies that aim to improve the search and so making the system more responsive. This paper also sugests how an ontology can be implemented, using metadata in learning object repositories to provide relevant aspects, such as interoperability, reuse, and searching.

Abstract-The online experimentation is in expansion inHigher Education Institutions, with a dynamic extension to all scientific areas. The integration of online labs in higher educational courses constitutes a significant financial saving way for the institutions with multiple benefits for student's learning. Without access and usage time restrictions, these labs provide a wide range of experiments, performed individually or in groups, repeated as often as needed, without any space or time restrictions, just imposing the Internet access is available and in good conditions. This paper describes a use case application of a web platform that integrates, monitors and controls different technologies, such as Wireless Sensor Networks, Virtual Sensor Networks and Data Acquisition Boards, through an Internet accessible RESTful API, using low-cost devices such as the Raspberry Pi. In this context, a remote laboratory is developed for students programming in Python, based on such platform to improve their programming skills, overcome their difficulties in CS1 and CS2 courses, and give the ability to interact to physical world through practical examples.

Abstract-A growing population world might exceed its food supply in the future. Food availability needs an increasing agricultural productivity and production through technology and innovation. European concerns about innovation policies reflected on the Lisbon Agenda include the European program PROPRURAL+ for the Portuguese Azores Islands. The agricultural innovation in the Azores started with the Green Revolution, which increased agricultural production, using seeds, fertilizers, chemical products and agricultural equipment. But much more innovation is needed for the Azores to became a wellsustained and competitive European region in this economic sector. For example, concerning milk, the region is responsible for more than 30% of the national production. But, since the liberalization in EU imposed by the global markets, a crisis in the sector is installed. Dairy producers are now facing many difficulties in trying to enhance the profitability of their farms, by reducing costs and improving efficiency. A characterization of the Azorean agriculture, emphasizing the milk production sector is presented. The specificities and the potential of the region are discussed and some agricultural innovations with IoT technologies are pointed out.
