This article considers some potential of activities developed in non-formal education in astronomy, like astronomical observatories and other related establishments. This kind of research is less explored in our country. We present, in this text, a model to study possible relations among these kinds of communities: the scientific, the amateur and the professional, applicable in astronomical observatories, in a motion against the local and punctual activities dispersion and pulverization of these establishments, and against the use of common sense to develop their activities, aiming the advancement of the astronomy education and its national research.

One tool that has been in evidence, especially among young people, is Facebook. It can be classified as a synchronous communication tool that allows communities of people with similar interests to discuss and exchange experiences in real time, promoting the sharing of information and the creation of collective knowledge, even if they being in different parts of the globe. In this paper we show that Facebook can be used as an educational tool to aid the work done in the classroom and the impact of creating closed groups in online social networking for educational purposes. The survey was conducted with a group of students at a private school in Bauru/SP. We investigated the interaction profile of students with a closed group created on Facebook and through a questionnaire analyzed whether students use virtual environments for personal or educational. The survey reveals students perceptions about relevant aspects and the potential use of this tool as teaching-learning strategy

As technology is more and more present within the organizations, the management of knowledge has become essential to an effective management. This article deals with the inseparable relation that exists in between knowledge management, practice communities and the social networks. The analysis over this relation allows us to observe how the Information and Communication Technologies facilitated the access, the information sharing and distribution within the organizations. By this, we highlighted the applicability in the social networks of three applications of Facebook, which can be used as tools in practice communities. This way, these tools are also developed for different technological platforms, which will allow a major interaction between the organizations and their workers, partners and even their clients. Therefore the responsible usage of these technologies and of the data generated by these tools can provide a better quality on the organizational knowledge management.

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.
