Concepción y desarrollo de la modalidad educativa Blended Learning o Modelo Integrado en el sistema universitario Iberoamericano.

Definir las condiciones y circunstancias en las que se desenvuelve el sistema universitario iberoamericano. Describir las características de la modalidad educativa Blended Learning o modelo integrado en el ámbito universitario de iberoamérica. Analizar las semejanzas, diferencias y combinaciones pedagógicas, tecnológicas y de gestión del modelo Blended Learning en la educación universitaria iberoamericana. Valorar las propuestas relevantes del modelo educativo Blendesd Learning en el sistema universitario iberoamericano. Formular un marco referencial de la modalidad educativa Blended Learning para entornos universitarios iberoaméricanos. Se ha trabajado con una población comprendida por los estudios y propuestas desarrolladas bajo la modalidad educativa Blended Learning en el ámbito universitario iberoamericano, integrada por los países (americanos y europeos) que conforman la Comunidad Iberoamericana de Naciones (CIN). La muestra está comprendida sobre la base de la población explicitada, se determinó de modo intencional, la decisión de seleccionar una experiencia relevante por país, es decir, considerar la valoración de la modalidad educativa de estudio en sólo una institución universitaria de cada uno de los países de la CIN; pudiendo ser esta, una práctica institucional o individual, y a partir de ella, realizar los análisis descriptivos y comparativos. En síntesis, la investigación comprendió 22 innovaciones. Para el proceso de selección, identificación, organización, análisis y comparación de la información de las experiencias acopiadas, se recurrió a las técnicas de la observación y del análisis del contenido. Pensar en Iberoamérica, en términos educativos, es concebir propuestas innovadoras sostenidas en los avances tecnológicos que se suceden en el orden mundial, y que son factibles de desarrollar en nuestra región. También, que es posible construir una macrocomunidad de enseñanza y aprendizaje, donde a pesar de nuestras diferencias de desarrollo socio-económico más son nuestras coincidencias en un futuro esperanzador. En ese sentido, estructurar un marco referencial de explicación de la modalidad educativa estudiada, es un imperativo irrenunciable para construir recreativamente un conocimiento compartido, que reúna nuestro saber y nos posicione en el ámbito internacional como un punto de referencia. Nuestra contribución en esa dirección ha sido cumplida aunque incipiente, sienta bases para seguir investigando la realidad, desde una visión de integración de nuestros pueblos.

Modelo dinâmico de simulação e otimização da força normal de reação do solo para um mecanismo de corte basal

The physical model was based on the method of Newton-Euler. The model was developed by using the scientific computer program Mathematica®. Several simulations where tried varying the progress speeds (0.69; 1.12; 1.48; 1.82 and 2.12 m s-1); soil profiles (sinoidal, ascending and descending ramp) and height of the profile (0.025 and 0.05 m) to obtain the normal force of soil reaction. After the initial simulations, the mechanism was optimized using the scientific computer program Matlab® having as criterion (function-objective) the minimization of the normal force of reaction of the profile (FN). The project variables were the lengths of the bars (L1y, L2, l3 and L4), height of the operation (L7), the initial length of the spring (Lmo) and the elastic constant of the spring (k t). The lack of robustness of the mechanism in relation to the variable height of the operation was outlined by using a spring with low rigidity and large length. The results demonstrated that the mechanism optimized showed better flotation performance in relation to the initial mechanism.

Modelo de programação quadrática para análise da movimentação logística e comercialização da soja brasileira

The purpose of this work was to analyze the logistical distribution of Brazilian soybean by applying a quadratic programming to a spatial equilibrium model. The soybean transportation system is an important part of the soybean complex in Brazil, since the major part of the costs of this commodity derives from the transportation costs. Therefore, the optimization of this part of the process is essential to a better competitiveness of the Brazilian soybean in the international market. The Brazilian soybean complex have been increasing its agricultural share in the total of the exportation value in the last ten years, but due to other countries' investments the Brazilian exportations cannot be only focused on increasing its production but it still have to be more efficient. This way, a model was reached which can project new frames by switching the transportation costs and conduce the policy makers to new investments in the sector.

Estrutura de um curso de taxonomia de campo: o modelo aplicado em Ubatuba, São Paulo

The field activities are essential for the education of a good taxonomist. The most common problems found in field activities are: a) large number of students, b) heterogeneous educational background and unlevelled knowledge of the participants, c) repetitions and tendency of collecting the more evidents life-forms. The causes and consequences of such problems are discussed herein. The proposed solution is a methodology, based on many years of experience in field courses for undergraduate and graduate courses. Topics about the ideal number of participants, area of coverage, period of activity, division of work and the necessary material and equipment are discussed. According to the number of species collected at the same place, this methodology may result in a list of local species with precise information about the life-forms, habitat, common names, frequency, uses, phenology and further information in this kind of work. The results of the aplication of this metodology in a field course held in the region of Ubatuba-SP are presented.

Análise bayesiana do modelo de herança monogênica no melhoramento vegetal: um exemplo com abobrinha

A common breeding strategy is to carry out basic studies to investigate the hypothesis of a single gene controlling the trait (major gene) with or without polygenes of minor effect. In this study we used Bayesian inference to fit genetic additive-dominance models of inheritance to plant breeding experiments with multiple generations. Normal densities with different means, according to the major gene genotype, were considered in a linear model in which the design matrix of the genetic effects had unknown coefficients (which were estimated in individual basis). An actual data set from an inheritance study of partenocarpy in zucchini (Cucurbita pepo L.) was used for illustration. Model fitting included posterior probabilities for all individual genotypes. Analysis agrees with results in the literature but this approach was far more efficient than previous alternatives assuming that design matrix was known for the generations. Partenocarpy in zucchini is controlled by a major gene with important additive effect and partial dominance.

Percepção dos usuários, profissionais de saúde e gestores sobre o modelo de atendimento oftalmológico no Hospital Regional de Divinolândia - São Paulo

Purpose: This study aimed to evaluate the assistance quality through the perception of the users and municipal health managers (mayors, health secretaries and screening team). Methods: A transversal and descriptive study was carried out. Results: The sample was comprised by 359 users and 48 managers. Medical assistance was considered excellent by 79.6% of the users, 93.7% of the managers, 87.5% of the health secretaries and 100% of the screening team. Reception received a great evaluation by 73.8% of the users and 93.8% of the selectors. Conclusion: The assistance model used at the Ophthalmologic Clinic of Divinolândia obtained a high level of satisfaction pleasing both users and managers.
