Princípios e fundamentos da pedagogia da alternância: alguns desdobramentos atuais

The Pedagogy of Alternation (PA) is a differentiated teaching methodology, originally created to meet the needs that involve the population of the field. Through its educational procedures, distinct from the traditional education, demand, with autonomy, to form children and young people through the articulation of time and space, and involve the family and community in the educational process and in local development. Having been established as an alternative that generated positive results, the PA has expanded the world and today, with the formation of various movements, is present on five continents. In Brazil, there are two active movements using the PA, the Italian, which afforded the EFAs and the French, responsible for implantation the CFRs. Is in this context, the present research is inserted, which the following objective: to analyse the origins, principles and theoretical-methodological foundations of Pedagogy of Alternation and its implantation in Brazil, as well as some of its current unfolding. With this, it takes into consideration, besides the Brazilian movements, those who influenced its origin, the raised in France and the raised in Italy. The study is characterized as a theoretical, qualitative, bibliographic and documental. The data collection was carried out by searching in the CEPAD/UTFPR database and in the web pages of the institutions involved. After the identification and selection of documents and bibliographies, was realized the qualitative analysis of the data. The results indicate that the Pedagogy of Alternation practiced by the Italian EFAs and the Brazilian CFRs has undergone significant changes over time, keeping only firm the principle alternation of time and space, while the French MFRs and Brazilian EFAs, passed by adaptations, but still solid to principles of PA. The survey also showed that the CFRs in Parana are in a situation of instability about their future, since the links with the government are weakened. Thus, the present study sought to reflect on the meaning and the scope of the PA and its foundations that guarantee the autonomy and strength of this methodology in their places of origin. Therefore, the research presents contributions regarding the elucidation about expansion process of the movements in the three covered countries as well as those faced tensions by each and their transformations in order to highlight the importance of PA for education, comprehensive training of young and to development of the middle.

Avaliação do potencial de Tillandsia recurvata (L.) L., Bromeliaceae, como bioindicadora da poluição atmosférica urbana

Air pollution can threat the environment and public health, and is assess by pollutant ́s concentration measurements in order to verify whether the limits set by environmental agencies are being respected. However, these measures do not indicate immediately the impacts to living beings. To faced this problem, plants are been investigated as potential bioindicators of air pollution and, among them, stand out bromeliads Tillandsia genus which colonize various substrates,. obtaining water and nutrients from the atmosphere directly. In this context, this research assessed the potential of epiphytic bromeliad Tillandsia recurvata (L.) L. found in urbanized areas of the city of Curitiba - PR as a bioindicator of urban air pollution. According to vehicle traffic, five sample points were selected and classified. Points P1 and P2 were classified as high-traffic vehicle due presenting trucks and urban transport; point P3 was classified as moderate traffic due the predominance of private vehicles and urban transport; and points P4 and P5 were classified as low-traffic, presenting circulation of private vehicles only. There were analyzed the abundance of T. recurvata, morphophysiological parameters (leaf area, leaf specific area, sclerophylly index, percentage dry weight / fresh weight, chlorophyll (a + b), analysis of structural mesophyll organization) and the heavy metals accumulation (Fe, Cd, Cr, Cu, Pb and Zn). The abundance analysis and the results obtained for metals analysis were correlated with the intensity of vehicular traffic, directing the sampling points P1 > P2 = P3 > P4 = P5. This result demonstrate that the abundance of T. recurvata is greater in urban air pollution impacted areas, thus indicating that T. recurvata absorbs and accumulates metals and can be used in biomonitoring of urban air pollution in areas impacted by vehicular traffic. Morphophysiological parameters analyzed shows that the internal plant ́s structure is not significantly impacted by urban air pollution due plant ́s adptations. The presence of absorbing scales, the CAM metabolism pathway and it ́s store water ability, among other features, demonstrate their potential as bio-indicator in urban areas, especially regarding heavy metals accumulation .

Sistema de gestão em segurança e saúde do trabalho (SGSST) integrando a norma OHSAS 18001 e NR-18: proposta para o setor da construção civil

The job security issue is crucial for the development of construction due to the need to ensure the health of workers, which is done by means of laws and production management. Thus, among various other laws, was enacted NR-18, in order to ensure the worker's minimum conditions for the development work. Despite legislative developments on the subject, they have become ineffective against the excessive number of accidents in the construction industry, bringing the company to greater in ensuring the health and safety of its workers. In view of this need for improvement of working environment in a general appearance, both for purposes of ensuring the law obedience as comfort for workers and quality of the organization, the System Health Management and Safety (OHSMS) is a valid tool demonstrates the evolution of business management, as well as OHSAS 18001 which proposes to ensure the efficiency and integration of a system geared to safety and health at work by means of implements and adaptations of it, in order to bring significant improvements to conditions of work, especially in the form of a new culture to be adopted by the company. Addressing the problem, this paper aims to develop a management system by OHSAS 18001 which is consistent with the terms of NR-18 as it is this integration of OHSMS Management System of the company as a usual practice of that aims at an improvement of work safety in the business of Buildings.
