Gestión de la carrera profesional en una empresa de servicios de tecnologías de información

110 p.El desarrollo de la carrera profesional al interior de una organización, se traduce en generar un diseño lógico sobre el crecimiento personal y profesional de sus integrantes, equilibrando intereses individuales y organizativos. El tema se lleva a cabo al interior de Synapsis, empresa dedicada al desarrollo e implantación de soluciones en el ámbito de las tecnologías de información, perteneciente al grupo Enersis. El mayor activo para este tipo de empresas son sus trabajadores y por lo tanto es de alta importancia gestionar sobre ellos. En el presente estudio luego de hacer un análisis de la organización, se introduce el concepto de competencias, se señala la importancia que toman en la gestión del capital humano y como van de la mano con la calidad de los productos. La gestión por competencias, en conjunto con los requisitos técnicos y desarrollo académico, constituyen la base de la gestión de la carrera profesional. El capítulo cuarto materializa el desarrollo del modelo de gestión de carrera profesional, donde se determinan: el modelo de competencias a utilizar, las competencias genéricas organizacionales y los niveles de desarrollo que presentan ellas, tanto en los cargos como en las personas. Todo esto, sumado a los requisitos técnicos y desarrollos académicos nos permite identificar los distintos niveles organizativos, los costos de promociones, y en definitiva establecer la carrera profesional. Otro aspecto de interés abordado en el estudio, es el hecho de determinar la asignación óptima de los trabajadores de Synapsis en los puestos que esta empresa les ofrece, basado en los costos de capacitación y desarrollo que se derivan de la gestión de la carrera profesional. Lo que se busca es asignar a las personas indicadas en los puestos indicados, sujeto a restricciones de costos. Esto se logra a través del desarrollo del modelo de asignación, que se enmarca dentro del ámbito de la investigación operativa y que entrega como resultado cuarenta y cuatro cambios en la actual distribución

Veamy: an extensible object-oriented C++ library for the virtual element method

This paper summarizes the development of Veamy, an object-oriented C++ library for the virtual element method (VEM) on general polygonal meshes, whose modular design is focused on its extensibility. The linear elastostatic and Poisson problems in two dimensions have been chosen as the starting stage for the development of this library. The theory of the VEM, upon which Veamy is built, is presented using a notation and a terminology that resemble the language of the finite element method (FEM) in engineering analysis. Several examples are provided to demonstrate the usage of Veamy, and in particular, one of them features the interaction between Veamy and the polygonal mesh generator PolyMesher. A computational performance comparison between VEM and FEM is also conducted. Veamy is free and open source software

Excitação ultravioleta em sistemas vítreos e cristalinos para aplicações em dispositivos ópticos

-Este projeto tem por objetivo o estudo dos processos ópticos chamados de conversão descendente de energia, nos quais energia luminosa Ultra Violeta pode ser convertida em visível e/ou infravermelha. Para tanto, propomos a expansão do alcance espectral da técnica de luminescência já disponível na UFJF, e que hoje opera na região do visível ao infravermelho, para incluir a região Ultra Violeta (UV) do espectro. Os sistemas de estudo propostos são materiais luminescentes com transições eletrônicas na região de 350 nm até 650 nm. Estas emissões podem ser originárias de níveis discretos de íons terras raras inseridos em sistemas vítreos ou amorfos, como também de transições entre a banda de condução e valência de semicondutores de gap largo. O interesse nessa região do espectro eletromagnético se dá em função da possibilidade de confecção de uma nova geração de dispositivos ópticos, como LEDs brancos, azuis e UV, lasers azuis e UV, displays planos RGB e lâmpadas fluorescentes sem mercúrio, nos quais o foco de estudo está centrado na obtenção de alta eficiência de conversão luminosa (e portanto baixa geração de calor)

Biodisponibilidad de fluoruro en dentífricos con carbón activado

23 p.Los dentífricos a base de carbón activado (CA) han surgido como una novedosa y atrayente formulación debido a sus potenciales múltiples efectos a nivel oral. Sin embargo, el CA se caracteriza por ser un excelente adsorbente natural de diversos componentes incluyendo fluoruro (F-), por lo que un dentífrico fluorado formulado con CA podría sufrir una reducción de F- biodisponible, reduciendo así su potencial para controlar lesiones de caries. Dado que esto no ha sido previamente demostrado, nuestra investigación determinó la concentración de F- biodisponible en dentífricos fluorados conteniendo CA. Dentífricos comercializados en Chile y EE.UU. fueron adquiridos en duplicado y con diferente número de lote (n=16). Flúor soluble total (FST) o biodisponible y el Flúor total (FT) fueron determinados utilizando un electrodo específico de F- acoplado a un potenciómetro previamente calibrado. Los resultados fueron expresados en ppm de Flúor (ppm F). La mayoría de los dentífricos contenían fluoruro de sodio (11 vs. seis con Monofluorofosfato como fuente de F-, y el abrasivo declarado en todos fue sílice. FST varió entre 970,5 ppm F a 1170,2 ppm F, encontrándose solo una muestra con niveles levemente inferiores a 1000 ppm F. Estos valores coincidieron con la concentración de FT declarada por el fabricante. En conclusión, la presencia de CA parece no reducir la concentración de F- biodisponible en dentífricos fluorurados con CA. Sin embargo, estos no deben ser recomendados hasta que futuros estudios demuestren su efectividad, o descarten sus potenciales efectos adversos

Effects of Plyometric Training on Explosive and Endurance Performance at Sea Level and at High Altitude

Plyometric training performed at sea level enhance explosive and endurance performance at sea level. However, its effects on explosive and endurance performance at high altitude had not been studied. Therefore, the aim of this study was to determine the effects of a sea level short-term (i.e., 4-week) plyometric training program on explosive and endurance performance at sea level and at high altitude (i.e., 3,270 m above sea level). Participants were randomly assigned to a control group (n = 12) and a plyometric training group (n = 11). Neuromuscular (reactive strength index – RSI) and endurance (2-km time-trial; running economy [RE]; maximal oxygen uptake - VO2max) measurements were performed at sea level before, at sea level after intervention (SL +4 week), and at high altitude 24-h post SL +4 week. The ANOVA revealed that at SL +4 week the VO2max was not significantly changed in any group, although RE, RSI and 2-km time trial were significantly (p < 0.05) improved in the plyometric training group. After training, when both groups were exposed to high altitude, participants from the plyometric training group showed a greater RSI (p < 0.05) and were able to maintain their 2-km time trial (11.3 ± 0.5 min vs. 10.7 ± 0.6 min) compared to their pre-training sea level performance. In contrast, the control group showed no improvement in RSI, with a worse 2-km time trial performance (10.3 ± 0.8 min vs. 9.02 ± 0.64 min; p < 0.05; ES = 0.13). Moreover, after training, both at sea level and at high altitude the plyometric training group demonstrated a greater (p < 0.05) RSI and 2-km time trial performance compared to the control group. The oxygen saturation was significantly decreased after acute exposure to high altitude in the two groups (p < 0.05). These results confirm the beneficial effects of sea level short-term plyometric training on explosive and endurance performance at sea level. Moreover, current results indicates that plyometric training may also be of value for endurance athletes performing after an acute exposure to high altitude

A vaccine therapy for canine visceral leishmaniasis promoted significant improvement of clinical and immune status with reduction in parasite burden.

Herein, we evaluated the treatment strategy employing a therapeutic heterologous vaccine composed of antigens of Leishmania braziliensis associated with MPL adjuvant (LBMPL vaccine) for visceral leishmaniasis (VL) in symptomatic dogs naturally infected by Leishmania infantum. Sixteen dogs received immunotherapy with MPL adjuvant (n = 6) or with a vaccine composed of antigens of L. braziliensis associated with MPL (LBMPL vaccine therapy, n = 10). Dogs were submitted to an immunotherapeutic scheme consisting of 3 series composed of 10 subcutaneous doses with 10-day interval between each series. The animals were evaluated before (T0) and 90 days after treatment (T90) for their biochemical/hematological, immunological, clinical, and parasitological variables. Our major results showed that the vaccine therapy with LBMPL was able to restore and normalize main biochemical (urea, AST, ALP, and bilirubin) and hematological (erythrocytes, hemoglobin, hematocrit, and platelets) parameters. In addition, in an ex vivo analysis using flow cytometry, dogs treated with LBMPL vaccine showed increased CD3+ T lymphocytes and their subpopulations (TCD4+ and TCD8+), reduction of CD21+ B lymphocytes, increased NK cells (CD5?CD16+) and CD14+ monocytes. Under in vitro conditions, the animals developed a strong antigen- specific lymphoproliferation mainly by TCD4+ and TCD8+ cells; increasing in both TCD4+IFN-?+ and TCD8+IFN-?+ as well as reduction of TCD4+IL-4+ and TCD8+IL-4+ lymphocytes with an increased production of TNF-? and reduced levels of IL-10. Concerning the clinical signs of canine visceral leishmaniasis, the animals showed an important reduction in the number and intensity of the disease signs; increase body weight as well as reduction of splenomegaly. In addition, the LBMPL immunotherapy also promoted a reduction in parasite burden assessed by real-time PCR. In the bone marrow, we observed seven times less parasites in LBMPL animals compared with MPL group. The skin tissue showed a reduction in parasite burden in LBMPL dogs 127.5 times higher than MPL. As expected, with skin parasite reduction promoted by immunotherapy, we observed a blocking transmission to sand flies in LBMPL dogs with only three positive dogs after xenodiagnosis. The results obtained in this study highlighted the strong potential for the use of this heterologous vaccine therapy as an important strategy for VL treatment
