Modelo de inventarios para control económico de pedidos en empresa comercializadora de alimentos

En el estudio que originó este artículo se elaboró una propuesta de mejora del sistema de inventarios para una comercializadora de alimentos en la ciudad de Santa Marta, a fin de lograr una reducción en los costos de inventario y un incremento en el beneficio económico de la organización, mediante la planificación y control de las compras y ventas de los productos. El proceso aplicado consiste en la clasificación de los productos manejados por la empresa con el método ABC, de acuerdo con la importancia de cada producto en el total de ventas de la distribuidora; posteriormente se aplicó el modelo de Cantidad Económica de Pedido –EOQ–, con el fin de sistematizar los conteos periódicos en los productos guardados en bodega, establecer los registros de las ventas realizadas, determinar la cantidad óptima de pedidos y el momento justo en el cual se debe pedir mercancía a los proveedores y las cantidades mínimas de reorden.

Sistematização do dimensionamento técnico e econômico de sistemas fotovoltaicos isolados por meio de programa computacional

One of the main referring subjects to the solar energy is how to compare it economically with other sources of energy, as much alternatives as with conventionals (like the electric grid). The purpose of this work was to develop a software which congregates the technical and economic main data to identify, through methods of microeconomic analysis, the commercial viability in the sizing of photovoltaic systems, besides considering the benefits proceeding from the proper energy generation. Considering the period of useful life of the components of the generation system of photovoltaic electricity, the costs of the energy proceeding from the conventional grid had been identified. For the comparison of the conventional sources, electric grid and diesel generation, three scenes of costs of photovoltaic panels and two for the factor of availability of diesel generation had been used. The results have shown that if the cost of the panels is low and the place of installation is more distant of the electric grid, the photovoltaic system becomes the best option.

VALOR ECONÔMICO AGREGADO POR HOSPITAIS UNIVERSITÁRIOS PÚBLICOS

The increasing participation of the society in the decision-making process related to public politics stimulates public administration in Brazil to search for mechanisms to demonstrate efficiency and disclosure in resource application. The main objective of this work is to calculate the economic value added to the society by Public University Hospitals. Therefore, a Public University Hospital case study has been carried out and its economic performance evaluated during a period of three years. This study has shown that the economic value added to the society in the long term by the entity is positive. The proposed value measurement has indicated that the society is getting a superior return from the opportunity costs of capital invested, that is, the hospital is constructing economic value and consequently contributing to the social welfare.

Primary to secondary LOTE articulation: A local case in Australia

In this study of articulation issues related to languages other than English (LOTE), "articulation" is defined and the challenges surrounding it are overviewed. Data taken from an independent school's admission documents over a 4-year period provide insights and reveal trends concerning students' preferences for language study, LOTE study continuity, and reasons for LOTE selection. The data also provides an accounting of some multiple LOTE learning experiences. The analysis indicates that many students who begin a LOTE in the early grades are thwarted in becoming proficient, because (1) continuation in the language is impossible due to unavailability of instruction; (2) expanded learning is hampered by teachers' inability to deal with a range of learners, (3) extended learning is hampered by administrative decisions or policies, or (4) students lose interest in the first LOTE and switch to another. Finally, a call is made for data gathering and research in local contexts to gain a better understanding of LOTE articulation challenges at the local, state, national, and international levels.

Compras p??blicas sustent??veis: uma experi??ncia de compra sustent??vel compartilhada no Instituto de Pesquisas Jardim Bot??nico do Rio de Janeiro

A Diretoria de Gest??o do Jardim Bot??nico do Rio de Janeiro (JBRJ), motivada em contribuir para ado????o de um novo paradigma de consumo na administra????o p??blica, implementou a compra compartilhada sustent??vel de 48 itens de material de expediente com 10 ??rg??os da administra????o p??blica federal. Essa foi considerada pelo Minist??rio do Planejamento, Or??amento e Gest??o (MP) como a primeira compra compartilhada sustent??vel do governo federal. O projeto, por ser compartilhado, permitiu efetivamente o ganho de escala, gerando uma economia de aproximadamente 50% do valor estimado. Os ??rg??os participantes e a equipe JBRJ empenharam-se com bastante motiva????o na implementa????o do projeto. O cadastramento dos produtos no ComprasNet permitiu a codifica????o dos primeiros produtos sustent??veis de material de expediente. Adotou-se, portanto, uma medida inovadora, que vai colaborar para a redu????o do impacto ambiental decorrente do consumo no ??mbito dos ??rg??os p??blicos, ao encontro da perspectiva do desenvolvimento sustent??vel
