Soils Security is a critical and growing global concern. The OpenSoils´ objective is to host, connect and share large amounts of curated soil data and knowledge at the Brazilian and South America level. The e-infrastructure consists of several layers of services, a database of soil profiles, a cloud-based computational framework to compute and share soil data integrated with a map visualization tools. OpenSoils is open, elastic, provenance-oriented and lightweight computational e-infrastructure that collects, stores, describes, curates, harmonizes and directs to various soil resource types: large datasets of soils profiles, services/applications, documents, projects and external links. OpenSoils is the first open science-based computational framework of soils security in the literature.

Os usos eficientes dos solos são problemas críticos que afetam vários países. O objetivo deste trabalho está na modelagem de um Sistema Agrícola de Próxima Geração (SAPG) para a área de Segurança de Solos. Apresentamos e avaliamos um serviço denominado do OpenSoils Edu que é parte de um SAPG voltado para gestão de dados pedológicos. O serviço é capaz de mapear grandes quantidades de dados de solos e pode ser utilizado por diversos tipos de usuários para visualização e compartilhamento de dados curados de solos.

This research aims to verify the impact of motivational factors on the intention of use of a Virtual Learning Environment. The environment studied was an e-government web application used by The Brazilian Ministry of Education offered to Brazilian high schools. In this preliminary approach, a case study was done in a private school in Rio de Janeiro followed by an experiment with 20 of its students. Qualitative and quantitative data allowed to endorse some of the results. Previous studies have indicated that teenagers tend to be motivated by playful environments, pointing to the importance of the perceived enjoyment factor. Nevertheless, in this study the perceived usefulness factor appeared as the greatest motivator for the intention of use of the adopted technology. The results of this study will be beneficial for increasing our understanding of new generation adoption of technology.
