La industria mundial de los cruceros turísticos registra un crecimiento sostenido por largo tiempo, su expectativa para los próximos años es alentadora y se sustenta en una atractiva rentabilidad y reducción de costos mediante la utilización de naves cada vez mayores, que están haciendo accesible esta nueva forma de hacer turismo a un segmento de personas cada vez más numeroso.Las rutas de Sudamérica, visitadas por una amplia variedad de armadores, han sido un reflejo del crecimiento de esta industria a nivel mundial, siendo necesario aprovechar esta oportunidad para brindar servicios que demandan importante cantidad de mano de obra y desarrollar la infraestructura portuaria para satisfacer a los requerimientos de naves y turistas evitando que éstos emigren a otras rutas.

Se aborda el binomio cadenas productivas y territorio, identificándose dos tipos de desarrollo: el "enclave" del Secano Interior y el de "encadenamiento potencial" entre dicho enclave y la Conurbación del Gran Concepción. Los beneficios de la cadena productiva forestal-celulosa, de importancia mundial, no llegan a su territorio, que permanece en la precariedad. El Gran Concepción, segunda conurbación industrial de importancia nacional, no logra conectarse virtuosamente con su entorno cercano mediante sus redes económicas, ni tampoco con la cadena forestal-celulosa del Secano Interior. El artículo se basa en datos de flujos económicos a partir de la matriz insumo-producto de 2008, en encuestas efectuadas en el contexto de un proyecto del Fondo Nacional de Desarrollo Regional (FNDR, 2008), y en el estudio sobre Chile y sus tipos de desarrollo (Falabella, 2000 y 2002). Finalmente, se plantea la necesidad de generar una plataforma política territorial para el desarrollo económico que facilite la rearticulación productiva.

Este trabajo tiene como objetivo presentar un análisis de la distribución espacial de la industria automotriz en el Brasil, entre 1995 y 2011, en relación con sus diversas categorías económicas, y mostrar sus encadenamientos sectoriales mediante las matrices interregionales de insumo-producto. A partir del cálculo del coeficiente de localización (QLij) de dicho período, se constató que la tercera ola de inversiones, iniciada en la segunda mitad de los años noventa, logró producir, de hecho, una ligera desconcentración espacial de este sector en la economía nacional. El cálculo del coeficiente de asociación geográfica (CAik) de diferentes años indicó una pequeña disminución, pese a que se mantuvo un nivel significativo de concentración, lo que sugiere que la producción de vehículos es un proceso bastante integrado con otras actividades económicas. Esta integración se corroboró, especialmente, con respecto a la compra de insumos (efectos hacia atrás) en todas las regiones aquí analizadas.

Este estudo teve como objetivo primordial analisar o impacto da atividade minero-metalurgica na qualidade de vida intramunicipal em Barcarena, a partir dos indicadores e índices sócioeconômicos nas dimensões renda, educação, habitação e saneamento, tendo como base de dados o Censo Demográfico Brasileiro de 1991 e 2000 do IBGE. Para tal, formulou-se a hipótese de que o acelerado crescimento econômico de Barcarena impulsionado, sobretudo pela minero-metalurgia não tem corroborado significativamente para a melhoria na qualidade de vida do município. Adotou-se como metodologia às análises comparativas temporal, intra e intermunicipal, tendo como embasamento para a discussão dos resultados obtidos uma revisão descritiva de diversos autores acerca do tema. Conclui-se que, embora a minero-metalúrgia não seja uma atividade promotora de um desenvolvimento econômico e humano originalmente endógeno, a população de Barcarena experimentou entre os anos de 1991 e 2000 uma leve melhora na qualidade de vida nos aspectos verificados. Conclui-se ainda que, as condições de vida dos moradores desse município poderiam ter sido melhores se a influência positiva dessa atividade não tivesse sido neutralizada pelo acelerado crescimento populacional

Currently, the food market is a great competition. It is no longer unanimously in the CMC powder drinks, as in the past, xanthan gum, always seeking to develop more economic alternatives, such as guar gum. It is clear, therefore, it is of vital importance to understand thoroughly the operation of a particular product in different process conditions and with different materials so that we can develop and adapt both new processes and products to new market reality

In uncertainly economic scenarios, an economic feasibility analysis must be done to accept a project based on investment criteria, such as NPV and IRR, mainly because the shareholders tend to invest their budget in a project if it has a great chance to return their investments. The studied company outsources all of its foundry services, what makes it very dependent of its suppliers, because the products have a lower quality level, long delivery periods and high prices. Therefore, this work will analyze the project of building an iron-casting foundry to decrease the dependence of its suppliers. In order to develop this research, all needed data related to the construction of the foundry and sales were collected to create deterministic and probabilistic (Monte Carlo Simulation) cash flows using MsExcel® and Oracle's Crystal Ball® software. As a result, the project was found to be risky by the NPV and IRR in the case of this new production line supplying only the internal needs. However, when the company offers its services to the foundry market, the project turns to be feasible

This work was developed with the aim of explaining the real benefits of using the concept of Lean Manufacturing in a Metallurgical Industry. Through this will highlight the strategies and real gains from the use of this methodology and therefore, the tools of Production Engineering that were used in the implementation of Lean Manufacturing, in order to improve processes in various aspects such as reduced handling, standardization of production, reduced time used in machine setup. Practical methods applied for the purpose of reducing waste become apparent. Also highlighted will be the real difficulties encountered in the implementation of Lean Manufacturing

Continuous improvement of industrial processes is one way to become companies more competitive in the market. For this, a fairly widespread use is the methodology of lean production systems, by eliminating waste. One of the tools of these systems is the method of rapid exchange of die or also called SMED, which will be applied in this study. The study aims to develop proposals for reducing the time of set up of two machines in two machining lines, watching also the ergonomics and safety conditions in this operations. The set up time reduction is justified among others, due to increase the machine productivity. In applying the connecting rod machining line, there were two types of exchange. Reductions in time to set up proposals reached values of 47% to one of them, and 55% to the other. It is important to underline that to reach this result, there was no need for large investments. In the application in block machining line, was developed an improvement in the ergonomic area. It was placed a pulley block that came to increase the time of tool change. Aiming to improve the security of the exchange, without productivity loss, the method was applied to reduce this time. It was developed two proposals.: the first would reduce that time by 19%, and does not require many resources of the company. The second involves the parallelization of the exchange, so that the reduction is 48%. However, this proposal requires one more manpower at the time of exchange and it is not always possible
