Psychosocial Identity of the adolescents in boarding school system in the agricultural education Abstract: This article is the result of a research where we try to study and to understand the psychosocial identity of adolescents undergoing boarding. We discussed the issue of boarding school in literature and notes about adolescence in various psychological approaches. Research strategies were interviews, and focus group reports. We conclude that, even with the difficulties students believe that the promising future can only be achieved through technical training, which would enable them not only to acquire a knowledge, but also as a way to gain access to a better-paying job. A better understanding of the surrounding reality allows us to subsidize various professional institutions also adopt boarding as an option to stay.

Apresentando uma síntese histórico-sociológica do panorama rural brasileiro, da constituição do ensino técnico, e do desenvolvimento do ensino técnico agrícola, este artigo defende que as escolas técnicas agrícolas sofrem uma dupla marginalização, por um lado proveniente de sua natureza profissionalizante e, por outro, dada sua vinculação com o meio rural brasileiro.

The study took place in a sewage treatment plant located at the actual Department of Water and Sewer in Bauru, city of Sao Paulo state. This treatment plant has an average entrance flow of 4.8 l. s-1 made by upflow anaerobic filter, followed by wetland systems constructed in parallel. . As objective of this study we evaluate the effectiveness of three systems of constructed wetlands, with three different types of plants (Lily pond, Giant papyrus and Cattail),quantify, and qualify the effluents at various stages of treatment to monitor their effectiveness and the possibility of reuse in agriculture. There was a satisfactory removal of organic matter, with a mean concentration of 36 and 39mg.l-1 at the , phases 1 and 2 of the operation, respectively. The constructed wetlands effluent nitrogen and phosphate concentrations were high throughout all the system and the removal efficiency of ammonia nitrogen was much lower than expected, then the system is functioning as secondary treatment and not as tertiary treatment. The concentrations of micro-organisms found in the final effluent were also high. Therefore, it is concluded that the results of removal efficiency of organic matter, of constructed wetland systems, meet the parameters required by legislation for effluent discharges but do not attend the parameters required for nitrogen and micro organisms. This way, these analyzed plants effluents are suitable for reuse in agriculture restricted irrigation
