Olhares acerca da construção cotidiana de uma escola do campo

The education of children and youth in the rural areas, with the social movements of struggle for land, returns to a place of relevance and is repositioned on the political agenda. This study aims to analyze the process of development and implementation of a pilot project of schools in the rural area of the city of Araraquara, focusing on the subjects’ perception of the region. We adopted a qualitative ethnographic approach, with the following instruments of data collection: participant observation and semi-structured interviews. It was found that the project which was built through a process of struggle of a community in an adversarial relationship with the municipal government, which itself is struggling in an exercise of cultural emancipation and the construction of citizenship. Thus it finds itself in a habit of cultural resistance and in areas that has its effects on representation and social transformation within the community. Notwithstanding, those who participated in the process of the struggle and implementation have been transformed along the way, salvaging their self-esteem, history and a sense of belonging to a community.

Etnicidade, conservação ambiental e direitos territoriais em áreas de incidência de programas de desenvolvimento social e sustentável

Ribeira Valley, a region covered by the last continues area of the Atlantic Rain Forest in São Paulo State, in Brazil, is thus a preservation law and environmental control target, is now configurated as locus where emerge conflicts concerning economic and agricultural activities, particularly in places where befall public policies recognizing territorial rights – quilombo remnants, indigenous lands and sustainable development settlings. The research’s aim is to understand, considering each of these contexts, if and how a conservationist focus is assumed as a value and a strategy, connected to etnicity and traditionality, in order to actualize these social spaces.

Influência da reinstrumentação do degrau apical radicular após o posicionamento primário do cone principal de guta-percha noselamento apical

The aim of this study was to evaluate in vitro the apical leakage after the apical re-preparation and replacement of the principal gutta-percha point plus endodontic sealer (Sealer 26TM). Sixty extracted human canines were prepared by using a step back technique up to size 50 K type file apically. At each change of instrument the canals were irrigated with distilled water. After that step, the external surface roots were coated and subdivided into six groups with ten roots each: I – single gutta percha point technique; II – lateral condensation and III – hybrid technique. The IV, V and VI groups were similar to others groups but after to place the principal gutta percha point, it was removed, re-prepared up to size 60K file and in sequence replaced the principal gutta percha point and the root canal filling finished. The specimens were immersed in 2% Rhodamine BTM for 7 days at 37 oC. The apical leakage was measured by Image ToolsTM program. With Kruskal Wallis test statistical analysis showed that there was no significant difference between the techniques (p > 0.05).

Circulação de textos midiáticos entre alunos de escola pública básica

The text characterizes the reading of media-related materials by students of the public basic education system in the State of São Paulo, based on a systematic observation of the circulation of press texts within the school daily life. In a study carried out during two academic years with groups of students from fundamental and secondary education classes belonging to two different schools situated in the outskirts of a town in the interior of the state, the students' reports on their appropriation of media-based information obtained from a variety of sources were analyzed, with particular emphasis on written newspapers. During the period investigated individual and group interviews, as well as texts produced by the students, were taken as points of departure for the analysis. Among the aspects noted from the contact with communication media is the establishment of press information inside the school, albeit with fragmentary repercussions, not fully integrated into the pedagogical daily life, but somewhat circumstantial in the students' lives. The themes that receive more attention circulate through the television, mediated by family or peers, but not by teachers. A proposal for the analysis of these data is made, followed by concrete suggestions as to the treatment to be given to support material, texts and media-based issues at school, taking into account the resources available and the school context such as it appears nowadays.

Implantes Platform Switching: longevidade e preservação óssea: revisão crítica da literatura

The concept of switching platform is the use of an implant by platform wider than the abutment. Recently, researches have shown that this type of dental implant design tends to offer a higher preservation of crestal bone when compared to the traditional pattern of bone loss. The present study aims to perform a critical review on the switching platform concept establishing possible advantages of the technique. A search was performed on Medline/Pubmed about the topic “dental implant” and “platform switching”, and after applying inclusion criteria 40 studies were selected. The literature on longevity present prospective studies that show less bone loss, studies in biomechanics exhibit better or similar stress distribution around the bone crest, however, is not yet defined the role of the biological width. Thus, studies of longevity, and randomized prospective studies are of a great relevance to be performed in order to confirm the benefits of this technique and to establish a protocol indication. It is possible, based on this literature review, to conclude that longitudinal and randomized studies show that the platform switching implants have longevity and less bone loss. Biomechanically, the technique is possible.

Construção de índice percentual de “status” de desenvolvimento sus-tentável de assentamentos rurais utilizando procedimento estatísti-co multivariado

The objective of the present work is the construction of percentual indexes of sustainable development "Status" - PIDSD (%) aiming to order and classify the rural settlements, considering agricultural, socioeconomic and environmental aspects, in order to diagnose their sustainable reality. This way, we considered multivariate statistical procedure to establish analytical descriptors - indexes - like the principal components technique (CP). The CP technique was used in a matrix formed by 47 variables observed in 50 rural settlements, distributed in seven different regions of the state of Mato Grosso, obtained from diagnostics, provided by "Mato-Grossense" Enterprise of Research, Assistance and Rural Extension S/A - EMPAER - MT, in order to obtain the indexes used in the construction of PIDSD (%). The settlements with higher PIDSD (%) were considered "higher potential" or "higher sustainable" in relation to the analyzed variables, making the establishment of assistance strategies and cooperation possible, allowing the government and civil society in general, to improve those with worse results ("lower potential" or "lower sustainable"), and search for ways to strengthen and multiply the results of the "higher potential" settlements. Vale do Seringal settlement had the best conditions in relation to the variables, mainly those of higher weigh and was considered the one with "higher potential". São Sebastião had the worst conditions and was considered "lower potential".

Manutenção da diversidade agrícola em assentamentos rurais: um estudo de caso em Moji-Mirim - SP, Brasil

Maintenance of agricultural diversity in rural settlements – a case study in Moji-Mirim, São Paulo, Brazil. This paper investigated whether farmers, when established in rural settlements, keep some traditional features with regard to crops diversity and circulation of planting material. Its aims were to make an ethnobotanical survey of species and varieties and analyze the dinamics of seeds and propagules circulation. A total of 139 varieties of food crops (55 species/28 families) were found, being 87% of them intended for self-consumption; 54% of varieties come from Minas Gerais, home state of most respondents. The number of varieties grown per household ranged from 17 to 54. The informal and free circulation of planting material is the most important way of acquisition. The circulation network is very active, showing a potential for the management of crops diversity, with emphasis on the contribution of settlers to the maintenance and valorization of traditional varieties.

Diagnóstico do uso de técnicas de calagem e aubação dos assentamentos rurais do estado de São Paulo: estudo de caso

In the context of the project “Development and qualification of agriculturists in the use of techniques for correction of theground in agricultural assentament”, the identification of the use of agricultural techniques becomes necessary as an important tool for decision taking, mainly in regards to the public politics of Assistance Technique and Agricultural Extension (ATER). In such a way, the present study it had for objectiveto diagnosis the use of limeand fertilization techniques in these agricultural assentamentin order to identify possible public politics ATER. Of the total of boarded families, 79.89% had answered to the questionnaire elaborated for this diagnosis. The field research was carried throughapplication of questionnaire elaborated for this study and the analysis of the results divided in profile of the beneficiaries, knowledge of techniques of ground handling and agricultural use of the areas of the Projects of Assentamentfor the beneficiaries. It was concluded that even so the great majority of the beneficiaries agricultural area and farmers to be declared diligent of this information are not in coherence with the one of knowledge of the type of ground, therefore, this type of understanding of the landscape is primordial for the taking of decision with regard to the agricultural use of the ground, moreover, the access to the knowledge and use of the techniques of limeand fertilization comes diminishing in the agricultural assentamentunder validity of II National Plan of the Agrarian Reformation, what it enters in total discord with the premises of the same. It fits here to detach the importance of public politics ATERdirected these beneficiaries of the Agrarian Reformation, mainly with regard to the ground handling.

Determinação das coordenadas dos vértices limítrofes de imóveis rurais utilizando-se do posicionamento GPS

Aiming to evaluate the methodologies of surveys related with the specifications of Geo-referencing Rural Parcels in Brazil, established by INCRA (National Institute of Colonization and Agrarian Reform), in attendance to the Law 10.267/01, and considering aspects of precision and accuracy, a test area was set up in the Assentamento Florestan Fernandes, in the county of Presidente Bernardes, SP. This area was subdivided in three sub-areas in order to simulate the existence of three contiguous rural parcels. The first stage of work consisted in the implantation and determination of the control points coordinates in their respective areas. These control points were determined by the process of direct transport, using dual frequency (L1/L2) GPS receivers and through the process of traverse with baselines of up to 20 km, using single frequency receivers (L1). The coordinates of the points of the perimeter of the three sub-areas were determined using single frequency GPS receivers, from two survey methods, both using static relative positioning. The first one, so called traverse, each point that delimits the property was occupied successively, starting from the control point and closing at another. In other, denominated double irradiation, each point of the property was irradiated from two control points. These procedures were accomplished with the intention to define and to implement a mistake control strategy, to realize redundancy measurements and to use an adjustment method correctly, to obtain trustworthily values in the patterns demanded in each kind of survey. With the data collected and processed some analyses could be accomplished from the discrepancies between the coordinates obtained by different methodologies. The results show that this test area may be used to validate other methodologies and equipments. The results were satisfactory and attended the specifications of Geo-referencing Rural Parcel.

Análise energética do milho em sistema de plantio direto, no assenta-mento rural da fazenda pirituba, Itaberá/SP

The aim of this work was to proceed, from the energetic point of view, an analysis of a corn agroecosystem, on the direct planting, located at Pirituba II rural workers placement project, Área III, city of Itaberá/SP. The energetic analysis mesured all operations, together with its fisical demands, the inputs and produced grains, classifying them within their respective flux, based on the definition of energy inputs and outputs, converting them into energetic equivalents and, so, determining the energetic matrix of de agroecosystem. The caloric index used were cultural efficiency and cultural liquid energy. The results showed the dependence of the studied systems on the chemical energy sources, from fertilizers (39,49%), agrotoxics (27,74%), and fossile energy of diesel (24,94%). The energetic values of the direct and indirect energy showed a very big difference between them, what means that the energy sources used in the system are not balanced. The cultural efficiency found was 12,86 and cultural liquid energy got to 115.025,92 MJ x ha-1. Later on, obtained data was compared to already existing data in Bueno (2002), who researched conventional planting system. The cultural inputs of both systems were energeticaly different: 9.696,97 MJ x ha-1 (direct planting), e 8.783,78 MJ x ha-1 (convencional planting). The outputs had very different results: 124.722,89 e 79.118,38 MJ x ha-1, respectively. So, we had much more cultural liquid energy on the studied system: 115.025,92 MJ x ha-1, compared to convencional system: 70.334,60 MJ x ha-1. The energectic loss of nitrogened fertilizers contributed for the high energetic loss of both energetic studied matrices. There are few contribution from biological energy source in both systems.
