Proposta de um modelo de gestão de custos para pequenas propriedades rurais familiares com foco na tomada de decisão

This work was general-purpose, develop a proposal of a theoretical model of decisionmaking with a focus on management of small family farms costs, which enables support for decision making. And the following objectives: i) develop a structured methodology, which allows to form a literary basis to provide scientific support for the implementation of research; ii) develop based on the literature the dimensions and variables of the necessary models to propose an application and iii tooling) to implement the proposed model within the dimensions and variables, and validate every stage background and perform the necessary conclusions to verify the effectiveness of applied model. In terms of methodology, we used a structured methodology, which allowed forming a bibliographic portfolio of 29 articles, and through the research constructs developed, based on an existing model, an activity segmentation model for aid farmer of small family farms in the decision-making process with emphasis on cost management. The model was applied in six family farms in the South West region of Parana and Santa Catarina West. With regard to the search results, it was identified that the model can be applied to the specific context for which it was created. It was also possible to identify that the proposed model was valid and relevant to aid in the management of family farms by identifying, through the targeting of productive activities, investment priorities guided by the balance between managing costs and return activities. Moreover, possible to target the activities of six surveyed properties, demonstrating that the property 02, has the shape of more complex segmentation should be divided into three groups of activities, which can be conducted in parallel without any restrictions between activities. Other properties have the segmentation of the simplest activities, allowing viewing in this way that there are activities of groups that require prioritizing investments. Specifically the property 01 and 04 have the highest priority investment target groups, the most prominent activities of groups representing respectively 49.32% and 47.40%, which are represented by grain production activities on the property 01 and grain production, beef cattle and eggs on the property 04.

A inserção da educação ambiental não formal no processo de implantação de saneamento ambiental na comunidade rural Colonia Mergulhão, São José dos Pinhais - PR

One of the biggest environmental problems of the population is the lack of sewage treatment, especially in rural communities and low-income. The development of technologies for efficient, low-cost sanitation need to be developed to meet the disadvantaged people of this basic service. This work was the implementation proposal of a technology called constructed wetlands, also known as Wastewater Treatment Plant for Roots Zone - ETEZR. The objective was to develop a non- formal environmental education proposal for redevelopment, using outreach methods for residents and deployment of this technology ETEZR in the rural community of Cologne Grebe in Sao Jose dos Pinhais - PR. With technical support from the Paranaense Technical Assistance and Rural Extension Institute -EMATER and the Federal Technological University of Paraná - UTFPR, 5 ETEZR were deployed in the colony through three theoretical and practical workshops, which involved total 67 people from the community 5 technicians EMATER and 13 of the Municipal Town Hall. Após4 months of implementation were carried out two collections of raw wastewater and treated to analyze physical, chemical and biological parameters. The results evaluated by chemical parameters BOD, COD, phosphorus, ammonia nitrogen comparing raw and treated sewage, demonstrate that ETEZR are effective in the treatment of sewage. 5 Seasons minimum and maximum efficiency between the basic parameters analyzed were 52.2 to 95.5% for BOD; 47 to 94.5% for COD; 21.5 to 96% phosphorus; 30-98% for ammonia nitrogen. Oils and greases, and a series of solid also achieved a significant reduction in their values when comparing the raw sewage and treated sewage, and biological parameters evaluated by means of coliforms showed a reduction of 80 to 99%. With the implementation of environmental education process aimed sanitation was possible to evaluate the perception of the population to accept the environmental sanitation technology using the ETEZR, understand the needs and sanitation concepts for the community. This research evaluated the development of the methodology applied by the non-formal environmental education in order to provide subsidies for rural sanitation plan process for the municipality.
