This work aimed to develop an optimization methodology for reservoir sizing in rainwater harvesting systems in order to increase the economic viability of projects in this area. For this, concepts of Operations Research were used so as to develop mathematical programming problems related to minimizing the life cycle cost and maximizing efficiency. The results obtained for different sizing methods were presented based on a case study, emphasizing the importance of tools that are able to provide a more accurate analysis and tend to significantly increase the economic viability of rainwater harvesting systems.

El fenómeno de la globalización está directamente relacionado a la expansión de mercados. Éstos no conocen fronteras e impactan la vida en todas las sociedades alrededor del mundo. En ese contexto, quedan fragilizados los que tienen menos poder de compra o poder tecnológico. Para sobrevivir a esta tendencia, comunidades se estructuran de modo a promover el desarrollo económico local. Son, así, conjugados esfuerzos por intermedio de planeamientos que involucran y estimulan la participación de actores locales. Una de las metodologías que se ha mostrado eficiente para un proyecto participativo es la PACA, acrónimo de Participatory Appraisal of Competitive Advantage. Este estudio busca presentar y reflexionar, por medio de una investigación bibliográfica, la posible intersección entre planeamiento participativo y las Relaciones Públicas, resaltando para tal, la metodología PACA. En resumen, la metodología PACA exige el establecimiento de un efectivo relacionamiento entre las personas y organizaciones involucradas para lograr sus objetivos. Es una técnica de planeamiento participativo que conduce al desarrollo económico local por promover la sinergia de actores de la comunidad. Como resultado de la investigación fue posible identificar que las actividades que dan soporte a la metodología PACA son intrínsecamente relacionadas a las actividades de Relaciones Públicas, a medida que es función primaria de estos profesionales el uso de destrezas educacionales y comunicacionales para promover el establecimiento de relacionamiento entre individuos con organizaciones, instituciones y entidades.

From the concept of Environmental Education proposed by I.U.C.N. in the 1970’s and considering some of the main teaching methodologies adopted in activities regarding Environmental Education, this paper aims to analyze the methodology named Pedagogy of the Project and presenting some alterations of this method, especially in relation to considered study unity: the watershed. Some teaching techniques are also presented, as well as didactic resources and considerations regarding the questions that can be developed for the students within the teaching or evaluation process. This purpose is complementary to others already existents and can be applied in many environmental or socioeconomics situations.

O presente trabalho se refere à análise dos Parâmetros Curriculares Nacionais na área de Matemática no ensino fundamental e sua inserção na disciplina de Conteúdos, Metodologia e Prática do Ensino de Matemática no curso de Licenciatura Plena em Pedagogia da Universidade Estadual Paulista, em Rio Claro/SP. Os Parâmetros Curriculares Nacionais a serem utilizados na pesquisa foram produzidos em 1997, enquanto que o programa de ensino de disciplina teve sua elaboração em 2006, sendo ainda vigentes. A pesquisa tem como objetivo evidenciar e detalhar a proposta de cada um destes documentos para verificar sua compatibilidade de modo a entender em que se fundamenta a formação de pedagogos acerca da área de Matemática e a atual necessidade para o ensino fundamental. A pesquisa foi complementada através da pesquisa bibliográfica, com abordagem qualitativa em autores que cerceiam o tema, além de legislações que contribuem, de modo que o debate literário colabore com a Educação uma vez que analisa o conteúdo estudado na graduação e sua compatibilidade com os parâmetros utilizados na faixa etária em que irá atuar

The objective of this work is to determine the membership functions for the construction of a fuzzy controller to evaluate the energy situation of the company with respect to load and power factors. The energy assessment of a company is performed by technicians and experts based on the indices of load and power factors, and analysis of the machines used in production processes. This assessment is conducted periodically to detect whether the procedures performed by employees in relation to how of use electricity energy are correct. With a fuzzy controller, this performed can be done by machines. The construction of a fuzzy controller is initially characterized by the definition of input and output variables, and their associated membership functions. We also need to define a method of inference and a processor output. Finally, you need the help of technicians and experts to build a rule base, consisting of answers that provide these professionals in function of characteristics of the input variables. The controller proposed in this paper has as input variables load and power factors, and output the company situation. Their membership functions representing fuzzy sets called by linguistic qualities, as “VERY BAD” and “GOOD”. With the method of inference Mandani and the processor to exit from the Center of Area chosen, the structure of a fuzzy controller is established, simply by the choice by technicians and experts of the field energy to determine a set of rules appropriate for the chosen company. Thus, the interpretation of load and power factors by software comes to meeting the need of creating a single index that indicates an overall basis (rational and efficient) as the energy is being used.

One of the important techniques to assist a tree improvement program is the grafting, which is used for the propagation of selected trees. The objective of this study was to evaluate the survival rate using a modified method of lateral grafting on Eucalyptus dunnii, Eucalyptus urophylla and a hybrid of Eucalyptus urophylla x Eucalyptus grandis. The work was conducted by the research teams of Eucatex and Palmasola companies, in September of 2011, and 589 grafts were made. The survival rate of the grafts was evaluated 180 days after grafting. Survival grafts rates were: 74% for E. dunnii, 55% for E. urophylla and 62% for the hybrid E. urophylla x E. grandis. These survival rates were higher than those currently obtained by the conventional method of eucalypt grafting. Thus, the method seems promising to assist in forest tree improvement programs, but further studies are still necessary to refine this grafting approach.
