Pertinencia de la formación técnica y tecnológica en el campo ocupacional

Education is a strategic factor in the economic, social and political development of the country. Therefore requires institutions that provide a service to the needs of society, they will form new generations, so it must develop the skills needed so that they can assume efficiently and responsibly the commitments demanded by the society of the 21st ce ntury. In this context, the theme of higher technical education is appearing today in various discussions of the Latin American social world, various social actors after years without mentioning a word about this area, have come out claiming it as an optio n real so that young people and adults can access to better living conditions. This text is a theoretical approach which is conceived as the vocational technical education to perform certain occupations and skilled trades that do not require high - level scientific or theoretical bases and focuses on the capacity - building practical and operational events seeking its transformation and improvement through learning by practice, the tradition and the trial and error to generate new knowledge. Educational technology is part of higher education, which aims to train highly qualified human resources to develop technology and innovate.La educación es un factor estratégico en el desarrollo económico, social y político del país. Por lo tanto se requieren instituciones que presten un servicio acorde a las necesidades de la sociedad, en ellas se formarán a nuevas generaciones, por lo que deberán desarrollar las competencias necesarias para que puedan asumir de forma eficiente y responsable los compromisos que demanda la sociedad del siglo XXI. En este contexto, la temática de la educación técnica superior está apareciendo hoy en día en diversos debates del mundo social  latinoamericano, diversos actores sociales luego de años sin mencionar palabra sobre esta área, se han pronunciado afirmándola como una opción real para que jóvenes y adultos puedan acceder a mejores condiciones de vida. Este texto es un abordaje teórico en el que se concibe la educación técnica como la formación práctica para desempeñar determinadas ocupaciones y oficios calificados que no requieren bases científicas o teóricas de alto nivel y se concentra en la formación de la capacidad práctica y operativa de los fenómenos buscando su transformación y mejoramiento a través del aprendizaje adquirido por la práctica, la tradición y el ensayo y error para generar nuevos conocimientos. La educación tecnológica es parte de la educación superior, que tiene como propósito formar recursos humanos altamente calificados para desarrollar tecnología e innovar

Mycorrhizal and endophytic richness and colonization in Cedrela odorata L., in agroforestry systems and secondary forest from southeastern Costa Rica

The roots of different forest species showmixed colonization by arbuscular mycorrhizal fungi(AMF) and dark septate fungi (DSE). In temper-ate ecosystems, AMF colonization and communitystructure change according to plantation age, whilecolonization by DSE is apparently unaffected. How-ever, in tropical ecosystems, little has been docu-mented on the possible changes caused by planta-tion age on mycorrhizal fungal communities. Weanalyzed AMF and DSE colonization and describedthe glomerospore community structure associatedwith three agroforestry systems of different Cedrelaodorata plantation ages (8, 13 and 17 years), in addi-tion to a secondary forest, during the dry season in southeastern Costa Rica. We detected statistical dif-ferences in total colonization in the agroforestry sys-tems with respect to the secondary forest (P < 0.05).Among the agroforestry systems, total colonizationwas higher in 8-year-old trees and DSE were onlydetected in agroforestry systems with higher coloni-zation in 8-year-old trees. The abundance and rich-ness of glomerospores were higher in the agroforestrysystems than in the secondary forest, with greaterrichness in younger plantations. We isolated 39 mor -phospecies, 27 from the plantations and 17 from thesecondary forest, with a greater representativeness ofAcaulospora and Glomus. We also provide four new AMF reports for Costa Rica (Acaulospora laevis, A.excavata, A. spinosissima, and A. bireticulata).Universidad de Costa Rica/[111-B9-137]/UCR/Costa RicaUniversidad de Costa Rica/[111-B3-078]/UCR/Costa RicaUCR::Vicerrectoría de Docencia::Ciencias Básicas::Facultad de Ciencias::Escuela de BiologíaUCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Básicas::Centro de Investigación en Biodiversidad y Ecología Tropical (CIBET

Caracterización de la logística en la empresa stockgi

Para nuestros lectores; El énfasis del Modelo Referencial en sí mismo es una investigación acerca de la Logística en una Red Adaptativa o Supply Chain, donde la consecuencia de su implementación no es otra cosa que la exposición objetiva del Sistema Logístico de una compañía o de una Red de Adaptativa. De tal manera que, al implementar los elementos del Modelo Referencial en Logística (trece elementos), y que se encuentran incluidos en una Red Adaptativa o Supply Chain (Cadena de Suministro), estos aplican para construir un conocimiento amplio y preciso con respecto a Logística en la Red Adaptativa o Supply Chain (Cadena de Suministro), que permiten crear estrategias de logísticas articuladas a las estrategias en Supply Chain Management, y desde luego en la estrategia del negocio o de la misma industria, que permiten formular los planes de formación y la capacitación en logística, generalmente para tomar las decisiones que estén orientadas al mejoramiento de la competitividad en las organizaciones.For our readers; The emphasis of the Reference Model itself is an investigation about the Logistics in an Adaptive Network or Supply Chain, where the consequence of its implementation is nothing else than the objective exposure of the Logistics System of a company or of an Adaptive Network. In such a way that, when implementing the elements of the Reference Model in Logistics (thirteen elements), and that are included in an Adaptive Network or Supply Chain, they apply to build a broad and precise knowledge regarding Logistics. in the Adaptive Network or Supply Chain, which allow the creation of logistic strategies articulated to the Supply Chain Management strategies, and of course in the strategy of the business or the industry itself, which allow to formulate the training plans and training in logistics, generally to make decisions that are aimed at improving competitiveness in organizations

Evolutive behavior towards cardiomyopathy of treated (nifurtimox or benznidazole) and untreated chronic chagasic patients Evolução à miocardiopatia dos infectados chagásicos crônicos tratados (nifurtimox ou benzonidazol) e não tratados

The aim of this work was to compare the evolution of chronic chagasic untreated patients (UTPs) with that of benznidazole or nifurtimox-treated patients (TPs). A longitudinal study from a low endemic area (Santa Fe city, Argentina) was performed during an average period of 14 years. Serological and parasitological analyses with clinical exams, ECG and X-chest ray were carried out. At the onset, 19/198 infected patients showed chagasic cardiomyopathy (CrChM) while 179 were asymptomatic. In this latter group the frequency of CrChM during the follow-up was lower in TPs compared with UTPs (3.2% vs 7%). Within the CrChM group, 2/5 TPs showed aggravated myopathy whereas this happened in 9/14 UTPs. Comparing the clinical evolution of all patients, 5.9% of TPs and 13% of UTPs had unfavourable evolution, but the difference is not statistically relevant. Serological titers were assessed by IIF. Titers equal to or lower than 1/64 were obtained in 86% of the TPs, but only in 38% of UTPs. The differences were statistically significant (geometric mean: 49.36 vs. 98.2). Antiparasitic assessment of the drugs (xenodiagnosis) proved to be effective. The low sensitivity in chronic chagasic patients must be born in mind. Despite treated patients showed a better clinical evolution and lower antibody levels than untreated ones, it is necessary to carry on doing research in order to improve therapeutic guidelines, according to the risk/benefit equation and based on scientific and ethical principles.<br>Para comparar a evolução dos infectados chagásicos crônicos não tratados (UTPs) e tratados (TPs) com nifurtimox ou benznidazol, fez-se um estudo longitudinal numa área de baixa endemicidade (cidade de Santa Fe, Argentina), com média de seguimento de 14 anos. Em cada controle foram feitas análises sorológicas e parasitológicas, exames clínicos, eletrocardiográficos e radiológicos. No inicio, 19/198 infectados apresentaram miocardiopatia chagásica crônica (MChCr), enquanto 179 eram assintomáticos. A frequência de MChCr no seguimento destes últimos foi 3,2% para os tratados e 7% para os não tratados. Dos pacientes com MChCr no início, 2/5 dos tratados e 9/14 dos não tratados agravaram sua miocardiopatia. Comparando a evolução clínica dos infectados, 5,9% dos tratados e 13% dos não tratados tiveram evolução desfavorável, mas esta diferença não é estatisticamente significativa. Na avaliação sorológica por IFI, 86% dos TPs e só 38% dos UTPs apresentaram títulos menores ou iguais a 1/64. As diferenças são estatisticamente significativas (média geométrica: 49,36 vs 98,2). Os xenodiagnósticos seriados realizados, demonstraram efetividade das drogas (considerar a baixa sensibilidade deste método na etapa crônica). Os pacientes tratados mostraram melhor evolução clínica e mais baixos níveis de anticorpos do que os não tratados. É preciso continuar as investigações para estabelecer pautas terapêuticas mais claras sobre a relação risco-benefício, sustentadas nos princípios científicos e éticos
