Desafios para a conquista do direito à moradia digna no assentamento Ilha

This booklet has been prepared from the actions for the university extension project entitled "Housing and Environment: building dialogue on urbanization of the settlement Ilha”. The study was conducted in a community located on the south end of the city of Almirante Tamandaré, among Barigui and Tanguá rivers. This project was conducted by a group of professors and students of the Federal University of Technology - Paraná (UTFPR), Campus Curitiba. The main objective was to investigate ways of intervention in housing and urbanization of the settlement Ilha, for the regularization of their properties. However, throughout the project, the group found that regularization of this settlement was not possible, in view of the risk of flooding on site. Therefore, this booklet provides information about the area and the rivers in their surroundings, on the positive aspects of living there, brings the story of some struggles of residents for better living conditions, as well as suggestions of funding sources for facilitating a possible relocation of existing families.

Complexos de estudo: investigando um experimento de currículo em uma escola de assentamento do MST no Paraná

The Landless Rural Workers Movement (MST) from its educational process and the path taken in education, started in the year 2013, with an experimental curricular proposal by Complexes of study the School Base and the Itinerant Schools, the MST, in Paraná state. For the construction of this proposed curriculum, the movement takes the historical background and the experience of the original foundations of the single school of labor started by the working class in revolutionary Soviet period as a training proposal and school organization that comes close to the creation of collective subjects, fighters and builders of a new society and sociopolitical objectives to this social movement. The Soviet experiment reference required a work of a critical appropriation for the Brazilian context. The curriculum prescription, called Study Plan, in its introduction, includes elements of design fundamentals like: the Education Eesign and Training Matrix; Matrix detailing: School and Life, School and Labor Formative Matrix, School and Social Struggle Formative Matrix, School and Collective Organization Formative Matrix, School and Culture Formative Matrix and School and History Formative Matrix; general school guidelines: a pedagogical function of the environment, the school's political organization, school times, specific methodological aspects, sequencing and duration of Complexes of Study and the evaluation process. The Study Plan contemplates the complexes, the disciplines, the portions of reality / practice categories present in complexes, organized by semester and year, i. e., from 6th to 9th grade in elementary school. Given the the presented context, this research aims to analyze the process of testing the proposed curriculum for the Complexes of Study in Primary School of Iraci Salette Strozak State School, located in the Marcos Freire Settlement, in Rio Bonito do Iguaçu in Paraná state. As a methodological approach, we chose the qualitative approach and analysis were conducted under the Marxism perspective. Library research and field research, semi-structured interviews and analysis of documents generated in the process of construction of the proposal were made.Initially, in this paper, we discus about the path followed by the MST in the fight for schools and public education; highlighting elements of the process which led to the understanding, by the Movement, of which only the struggle for land is not enough for the realization of Agrarian Reform. Then discuss whether some elements of Pedagogy of the Movement, the concept of education and the goals for education that Social Movement, the training matrices and the potential to transform the school from a pedagogical proposal that has these elements as guiding. They present also the original foundations of Complexes Study in its historical origin and design. Is discussed about the changes and curriculum innovations, curriculum as schooling as social reproduction and presents the structure of Curriculum Proposal by Complex of Study. Forth, it is shown how the experiment occurred in basis School Iraci Salette Strozak. At this point, we propose a dialogue on the transformations in the organization of pedagogical work, discussing the elements of the proposal that are being experienced and the changes already perceived. Still, we address the issue of formation of educators and also elements relating to the challenges andadvancements encountered by the school in this area, and possible implications for the experiment.

Moradia e meio ambiente: extensão universitária e compromisso social

This book’s guideline is a description of the activities developed during the University Extension project entitled "Housing and Environment: building dialogue over the urbanization of the settlement Ilha", located in the Metropolitan Region of Curitiba. This project was coordinated by professors from the Federal University of Technology - Paraná (UTFPR). The initial objectives of the extension project were to investigate ways of intervention on the scenario of poor conditions of housing and urbanization of the settlement Ilha, for their land regularization. The book tells the story of the extension project, showing how the initial goals have changed with time. In addition, this book describes the frustrations and the learning process along the way, from the view of professors and students of UTFPR who actively participated in this project. This book also intends to report the feelings that the villagers attributed to their place of residence; the joys, stumbling and learning by using a participatory methodology from what Paulo Freire says about popular education. Moreover, the book brings the confrontation between the technical and popular vision on the regularization of the area.

Medidas de concentração de radônio proveniente de argamassas de cimento portland, gesso e fosfogesso

Portland cement being very common construction material has in its composition the natural gypsum. To decrease the costs of manufacturing, the cement industry is substituting the gypsum in its composition by small quantities of phosphogypsum, which is the residue generated by the production of fertilizers and consists essentially of calcium dihydrate and some impurities, such as fluoride, metals in general, and radionuclides. Currently, tons of phosphogypsum are stored in the open air near the fertilizer industries, causing contamination of the environment. The 226 Ra present in these materials, when undergoes radioactive decay, produces the 222Rn gas. This radioactive gas, when inhaled together with its decay products deposited in the lungs, produces the exposure to radiation and can be a potential cause of lung cancer. Thus, the objective of this study was to measure the concentration levels of 222Rn from cylindrical samples of Portland cement, gypsum and phosphogypsum mortar from the state of Paraná, as well as characterizer the material and estimate the radon concentration in an environment of hypothetical dwelling with walls covered by such materials. Experimental setup of 222Rn activity measurements was based on AlphaGUARD detector (Saphymo GmbH). The qualitative and quantitative analysis was performed by gamma spectrometry and EDXRF with Au and Ag targets tubes (AMPTEK), and Mo target (ARTAX) and mechanical testing with x- ray equipment (Gilardoni) and the mechanical press (EMIC). Obtained average values of radon activity from studied materials in the air of containers were of 854 ± 23 Bq/m3, 60,0 ± 7,2 Bq/m3 e 52,9 ± 5,4 Bq/m3 for Portland cement, gypsum and phosphogypsum mortar, respectively. These results extrapolated into the volume of hypothetical dwelling of 36 m3 with the walls covered by such materials were of 3366 ± 91 Bq/m3, 237 ± 28 Bq/m3 e 208 ± 21 Bq/m3for Portland cement, gypsum and phosphogypsum mortar, respectively. Considering the limit of 300 Bq/m3 established by the ICRP, it could be concluded that the use of Portland cement plaster in dwellings is not secure and requires some specific mitigation procedure. Using the results of gamma spectrometry there were calculated the values of radium equivalent activity concentrations (Raeq) for Portland cement, gypsum and phosphogypsum mortar, which were obtained equal to 78,2 ± 0,9 Bq/kg; 58,2 ± 0,9 Bq/kg e 68,2 ± 0,9 Bq/kg, respectively. All values of radium equivalent activity concentrations for studied samples are below the maximum level of 370 Bq/kg. The qualitative and quantitative analysis of EDXRF spectra obtained with studied mortar samples allowed to evaluate quantitate and the elements that constitute the material such as Ca, S, Fe, and others.
