el primer capitulo de esta monografía, se va a entender de una manera concisa cual es la dinámica de funcionamiento de la industria automotriz en general, teniendo en cuenta sus diversas facetas, como lo son el ensamblaje automotriz y algunos aspectos de cómo se maneja en negocio en el ámbito comercial y su importancia dentro de la economía de los estados. En el segundo capitulo se contextualizara e ubicara dentro de un ámbito regional, pasando por como se estructura a nivel de la Comunidad Andina de Naciones (CAN), hasta llegar al panorama local colombiano, enfocándose en la General Motors Colmotores, como la ensambladora mas fuerte del mercado Colombiano en la actualidad. En el tercer capitulo se establecerá cual es el marco jurídico que rige al sector automotriz, partiendo desde una perspectiva subregional, con el estudio del convenio automotor andino, el cual se convierte en el piso jurídico del sector en el marco del TLC Estados Unidos – Colombia. En el cuarto capitulo se estudiara el caso de éxito de de la industria automotriz mexicana, bajo el marco del TLC México- Estados Unidos, el cual sirvió como factor de consolidación para el sector. Por ultimo se darán las conclusiones del estudio del tema y se emitirán unas pequeñas recomendaciones.

From the example of the process of general induction into the organization and using certain sociological resources, shows paradox are specialists in human management: is to carefor the motivation and the welfare of workers to achieve its high performance, their fidelity and his tenure at the company; However, current mutations of the social architecture in general and of work in particular –as structure of organized action– force thinking that organizational loyalty tends to be increasingly unlikely and that, conversely, the current personnel administration processes appear made inappropriate notions and appear to contribute directly to the adversities of human beings in organizational settings.

Trabajo de grado enfocado a determinar la asociaciónexistente entre manipulación manual de cargas y la presencia de lumbalgia entrabajadores de un área determinada en una empresa ensambladora devehículos. Se abordan temas como anatomía y biomecánica de la columnalumbar, levantamiento manual de carga, lumbalgia y factores que contribuyen ala presencia de esta, los cuales sirvieron de soporte teórico en este trabajo.Esta es una investigación de tipo descriptivo, la cual se desarrolló en tres fases:revisión teórica, trabajo de campo y análisis y procesamiento de la información;concluyendo que existe una asociación entre la manipulación manual de cargasy la presencia de lumbalgia en los trabajadores del área estudiada, teniendoademás como resultados adicionales que la lumbalgia tiene un origenmultifactorial y los factores psicosociales juegan un papel importante en lapresencia de esta.

This study covers an area of great importance in the research of breast cancer, related to the study of the effects of both estrogens (E2) and anti-estrogens (Tamoxifen) on chromosomes and of modulation of gene expression. Considering that breast cancer is a very heterogeneous disease and that patients respond differently to treatment, the identification of chromosomal abnormalities as well as genes responsive to 17β-estradiol (E2) and Tamoxifen (TAM) could provide the necessary framework to understand the complex effects of this hormone in target cells and could explain, at least in part, the development of cellular resistance to TAM treatment and the subsequent best therapeutic option. In this order of ideas, we determined the effects of E2 and TAM on the chromosomes and on the modulation of gene expression in four breast cancer cell lines, which represent three of the five subtypes of breast cancer known at present. The results are presented in six chapters - each one has a group of the results achieved around the cytogenetic characteristics and gene expression profiles of four cell lines and the effects of E2 and TAM incubation on those. The first chapter describes the main features of breast cancer, furthering the use and effects of E2 and TAM treatment.

Se confecciona un repertorio de juegos motores tradicionales. La secuencia lógica que sigue es partir de la realidad más cercana e+ inmediata para acercarse a otras culturas más alejadas. Se pone de manifiesto el carácter transcultural, casi universal, de esta manifestación humana. El estudio ofrece cincuenta juegos motores tradicionales de Cataluña y de todo el mundo. Se refuerza la utilización del juego como recurso y fuente de aprendizaje, con la intencionalidad educativa que en la práctica lúdica ayude a establecer relaciones basadas en el respeto y la tolerancia, favoreciendo la integración escolar y social con los alumnos, sobre todo de la población escolar con necesidades educativas específicas.

Ribonucleases are promising agents for use in anticancer therapy. Among the different ribonucleases described to be cytotoxic, a paradigmatic example is onconase which manifests cytotoxic and cytostatic effects, presents synergism with several kinds of anticancer drugs and is currently in phase II/III of its clinical trial as an anticancer drug against different types of cancer. The mechanism of cytotoxicity of PE5, a variant of human pancreatic ribonuclease carrying a nuclear localization signal, has been investigated and compared to that of onconase. Methods: Cytotoxicity was measured by the MTT method and by the tripan blue exclusion assay. Apoptosis was assessed by flow cytometry, caspase enzymatic detection and confocal microscopy. Cell cycle phase analysis was performed by flow cytometry. The expression of different proteins was analyzed by western blot.n Results: We show that the cytotoxicity of PE5 is produced through apoptosis, that it does not require the proapoptotic activity of p53 and is not prevented by the multiple drug resistance phenotype. We also show that PE5 and onconase induce cell death at the same extent although the latter is also able to arrest the cell growth. We have compared the cytotoxic effects of both ribonucleases in the NCI/ADR-RES cell line by measuring their effects on the cell cycle, on the activation of different caspases and on the expression of different apoptosis- and cell cycle-related proteins. PE5 increases the number of cells in S and G2/M cell cycle phases, which is accompanied by the increased expression of cyclin E and p21WAF1/CIP1 together with the underphosphorylation of p46 forms of JNK. Citotoxicity of onconase in this cell line does not alter the cell cycle phase distribution and it is accompanied by a decreased expression of XIAP. Conclusions: We conclude that PE5 kills the cells through apoptosis associated with the p21WAF1/CIP1 induction and the inactivation of JNK. This mechanism is significantly different from that found for onconase

Na sequência da integração da energia eólica em larga escala foram estabelecidos códigos de rede pelos vários operadores de sistema, exigindo que os parques eólicos permaneçam em serviço durante e após a ocorrência de defeitos na rede a montante. Nos parques eólicos equipados com sistemas de velocidade constante este requisito pode ser assegurado pela instalação, no ponto de interligação à rede, de equipamento de compensação dinâmica de potência reactiva, controlado como fonte de tensão, sendo as funções de controlo baseadas em medidas efectuadas no ponto de interligação relativamente às componentes directas da tensão e da corrente. Como a adopção deste tipo de soluções externas é adequada ao funcionamento do sistema em regime equilibrado, este artigo foca a avaliação do desempenho da solução no caso da ocorrência de defeitos assimétricos. Os resultados obtidos através das simulações dinâmicas evidenciam o aparecimento de sobre tensões nas fases não afectadas pelo defeito que poderão colocar o parque eólico fora de serviço.

The relations between soil electrical conductivity (ECa) and top- and sub-soil physical properties were examined for an arable field in England. The correlation coefficients between ECa and the soil particle size fractions were large and their cross variograms showed that the coregionalization was also strong. The coregionalization was stronger for the subsoil properties than for the topsoil, the reverse to the correlation coefficients. The relations between ECa and some soil properties, such as clay and water content, appear complex and emphasize that a map of ECa cannot substitute for sampling the soil.
