All over the world, organizations are becoming more and more complex, and there’s a need to capture its complexity, so this is when the DEMO methodology (Design and Engineering Methodology for Organizations), created and developed by Jan L. G. Dietz, reaches its potential, which is to capture the structure of business processes in a coherent and consistent form of diagrams with their respective grammatical rules. The creation of WAMM (Wiki Aided Meta Modeling) platform was the main focus of this thesis, and had like principal precursor the idea to create a Meta-Editor that supports semantic data and uses MediaWiki. This prototype Meta-Editor uses MediaWiki as a receptor of data, and uses the ideas created in the Universal Enterprise Adaptive Object Model and the concept of Semantic Web, to create a platform that suits our needs, through Semantic MediaWiki, which helps the computer interconnect information and people in a more comprehensive, giving meaning to the content of the pages. The proposed Meta-Modeling platform allows the specification of the abstract syntax i.e., the grammar, and concrete syntax, e.g., symbols and connectors, of any language, as well as their model types and diagram types. We use the DEMO language as a proofof-concept and example. All such specifications are done in a coherent and formal way by the creation of semantic wiki pages and semantic properties connecting them.

Este trabalho tem o objectivo de criar um Editor e Visualizador Web de Formas de Onda para controladores digitais especificados com modelos Redes de Petri Input-Output Place-Transition (IOPT). Após uma análise das ferramentas existentes e constatando-se a inexistência de uma ferramenta adequada a essa função, desenvolveu-se uma ferramenta denominada Wave4IOPT, que permite a visualização das formas de onda de sinais e eventos de entrada e de saída ao longo do tempo. A ferramenta permite também a visualização dos resultados do histórico de uma simulação de uma Rede de Petri IOPT, proveniente do Simulador das IOPT-Tools. Esta ferramenta incorpora funcionalidades de edição, modos de visualização e um módulo básico de identificação e correcção de erros dos valores das formas de onda. O Wave4IOPT está disponível a partir de um browser e prevê-se que venha a estar integrado no ambiente de ferramentas IOPT-Tools. Esta ferramenta foi construída utilizando tecnologias Web como HTML, JavaScript, CSS, SVG e JSON. Adicionalmente, o Wave4IOPT poderá também servir para a edição, visualização e análise de outros tipos de sinais digitais, desde que sejam preenchidos os requisitos da estrutura do ficheiro JSON que será lido pela ferramenta.

WebGraphEd is an open source software for graph visualization and manipulation. It is especially designed to work for the web platform through a web browser. The web application has been written in JavaScript and compacted later, which makes it a very lightweight software. There is no need of additional software, and the only requirement is to have an HTML5 compliant browser. WebGraphEd works with scalable vector graphics (SVG), which it makes possible to create lossless graph drawings.

Introducción: Fueron calificados en Colombia con pérdida de la capacidad laboral (PCL), de Incapacidad Permanente Parcial (5%-49%), 54.272 casos, de los cuales en el Departamento del Meta se calificaron 730 casos. Objetivo: Establecer los factores sociodemográficos y laborales asociados con la calificación de PCL de patologías de origen laboral y común por la Junta Regional de Calificación de Invalidez del Meta (JRCIM) (2012-2013). Metodología: Estudio de corte transversal, observacional, con una población muestra de 1.140 registros de personas calificadas con pérdida de la capacidad laboral entre 2012-2013, la información se recolectó mediante la base de datos de pacientes calificados en la JRCIM, en donde se indagó sobre los factores sociodemográficos, laborales y porcentaje de PCL. Resultados: 73.6 % de la población fueron de género masculino, la actividad económica que predominó fue la de servicios domésticos con el 76.5%, la mayoría desempeñaba el cargo de oficios varios con el 6%, el 53.7 % fueron calificados con PCL del 16 – 30 %. No se evidenció asociación estadísticamente significativa entre el porcentaje de PCL y factores laborales y socio-demográficos. Conclusiones: La calificación de PCL, en el Meta está marcada por factores tales como la edad y el género masculino, igualmente la actividad económica que predominó fue la de servicios domésticos, transporte y educación, estos sectores deben ser intervenidos en términos de vigilancia epidemiológica para prevenir estados de incapacidad permanente parcial e invalidez.

La enfermedad de disco lumbar de origen laboral se presenta como una patología frecuente a nivel mundial en la masa trabajadora de diferentes sectores económicos expuesta a factores de riesgo biomecánico, afectando negativamente a la persona como ser individual y social, y repercutiendo en las economías en diferentes niveles. Objetivo Establecer la prevalencia de los factores de riesgo biomecánico en los casos con diagnóstico de enfermedad de disco lumbar calificados como enfermedad de origen laboral por la Junta Regional de Calificación de Invalidez del Meta, en el período comprendido entre 2011 a 2014, explorando la asociación entre los factores sociodemográficos y laborales. Metodología: Estudio de corte transversal con información retrospectiva de historias clínicas de pacientes con enfermedad de disco lumbar calificados de origen laboral, entre el 2011 – 2014. Resultados: La prevalencia de los factores de riesgo biomecánico fue: flexión columna con 94.1%, caminando durante la mayor parte de la jornada laboral 51.7%, levantar y/o depositar manualmente objetos 53.4%, manipulación de carga mayor a 25 kg, 49.2% y vibración cuerpo entero más de 4 horas 16.9%. Estos factores fueron mayores en trabajadores de obras civiles y manipuladores de materiales con 20.3%, en actividades económicas de servicios con 33.1% y construcción 21.2%. Se encontró asociación estadísticamente significativa de la enfermedad de disco lumbar con el género y la exposición a vibración/impacto cuerpo entero. Conclusión: Los factores de riesgo biomecánico como la posición de la columna vertebral en flexión, el levantamiento y depósito de carga, la manipulación de peso mayor a 15 kgs, la postura de cuerpo caminando, la exposición a vibración a cuerpo entero, y el tiempo de exposición, son elementos fundamentales a tener en cuenta en el proceso de calificación de origen de la enfermedad discal lumbar.

Resumen Introducción Una posible opción de tratamiento para el manejo del trastorno depresivo mayor (TDM) es la estimulación magnética transcraneal (EMT) que ha mostrado propiedades antidepresivas superiores al placebo con un buen perfil de seguridad. El objetivo del presente trabajo es determinar la reducción en la severidad del TDM y la proporción de eventos adversos (EA) en pacientes con TDM refractario y no refractario, posterior al uso de EMT administrada en monoterapia o tratamiento coadyuvante comparado con terapia farmacológica. Metodología Se planteó una pregunta PICOT de la cual se realizó una búsqueda sistemática de estudios clínicos en las bases de datos Medline, EMBASE y Cochrane. Dos investigadores en forma independiente realizaron la selección de artículos, evaluación de calidad con la herramienta de la colaboración Cochrane y extracción de datos. Se extrajeron datos de eficacia como tasa de respuesta, porcentaje de remisión, calidad de vida, diminución sintomática del trastorno depresivo mayor en la escala de Hamilton y capacidad funcional. Igualmente, proporción de pacientes con EA. Se realizó un meta-análisis de estas variables teniendo en cuenta la heterogeneidad. Resultados La presente revisión sistemática incluyó 26 estudios clínicos aleatorizados de baja calidad metodológica mostrando que la EMT presentó una eficacia superior cuando es usada como coadyuvante a las terapias con que venían siendo tratados los pacientes con TDM refractario y no refractario en los desenlaces de tasa de respuesta y porcentaje de remisión. En el caso de intervenciones farmacológicas específicas, la EMT presento eficacia similar, tanto en terapia coadyuvante como en monoterapia comparado con las intervenciones farmacológicas. En cuanto a seguridad, la EMT presenta un buen perfil de seguridad debido a que en todos los escenarios estudiados los EA fueron no serios y baja frecuencia Conclusiones La evidencia disponible sugiere que la EMT mostró ser efectivo y seguro para el manejo del TDM refractario y no refractario. Sin embargo, la evidencia es débil por lo tanto se necesita mayor investigación clínica que soporte su uso.

As the world evolves, organizations are becoming more and more complex, and the need to understand that complexity is increasing as well. With this demand, arises organizational engineering, which is a subject that emerged with the purpose to make organizations easier to understand, by putting in practice the concept of organizational self-awareness, which means that that the collaborators who are part of an organization, need to understand it and know what their role in it is. The DEMO methodology (Design Engineering Methodology for Organizations), came up with the purpose of representing these organizations’ self-awareness, through the definition and creation of consistent and coherent diagrams. Semantic wikis have features that can help in enterprise modelling. UEAOM (Universal Enterprise Adaptive Organization Model) is a model that allows the specification and dynamic evolution of languages, meta-models, models, and their representations as diagrams and tables. In this project, it was implemented a system based on UEAOM, and Semantic Media Wiki which allows a graphical creation and edition of diagrams. UEAOM can be divided into the meta-modeling level where a language is defined, and the modelling level where instances of classes of that language are created. The system we developed focuses on the modeling level, but will takes as a basis the project that focuses on meta-modeling. The DEMO language was used as an example for the implementation and tests of a graphical editor, based in web technologies and SVG, integrated with SemanticMediaWiki to allow an intuitive, coherent and consistent navigation and editing of organization diagrams.

Ecosystem engineering is increasingly recognized as a relevant ecological driver of diversity and community composition. Although engineering impacts on the biota can vary from negative to positive, and from trivial to enormous, patterns and causes of variation in the magnitude of engineering effects across ecosystems and engineer types remain largely unknown. To elucidate the above patterns, we conducted a meta-analysis of 122 studies which explored effects of animal ecosystem engineers on species richness of other organisms in the community. The analysis revealed that the overall effect of ecosystem engineers on diversity is positive and corresponds to a 25% increase in species richness, indicating that ecosystem engineering is a facilitative process globally. Engineering effects were stronger in the tropics than at higher latitudes, likely because new or modified habitats provided by engineers in the tropics may help minimize competition and predation pressures on resident species. Within aquatic environments, engineering impacts were stronger in marine ecosystems (rocky shores) than in streams. In terrestrial ecosystems, engineers displayed stronger positive effects in arid environments (e.g. deserts). Ecosystem engineers that create new habitats or microhabitats had stronger effects than those that modify habitats or cause bioturbation. Invertebrate engineers and those with lower engineering persistence (<1 year) affected species richness more than vertebrate engineers which persisted for >1 year. Invertebrate species richness was particularly responsive to engineering impacts. This study is the first attempt to build an integrative framework of engineering effects on species diversity; it highlights the importance of considering latitude, habitat, engineering functional group, taxon and persistence of their effects in future theoretical and empirical studies.

Chlorophenylpiperazines (CPP) are psychotropic drugs used in nightclub parties and are frequently used in a state of sleep deprivation, a condition which can potentiate the effects of psychoactive drugs. This study aimed to investigate the effects of sleep deprivation and sleep rebound (RB) on anxiety-like measures in mCPP-treated mice using the open field test. We first optimized our procedure by performing dose-effect curves and examining different pretreatment times in naïve male Swiss mice. Subsequently, a separate cohort of mice underwent paradoxical sleep deprivation (PSD) for 24 or 48h. In the last experiment, immediately after the 24h-PSD period, mice received an injection of saline or mCPP, but their general activity was quantified in the open field only after the RB period (24 or 48h). The dose of 5mgmL(-1) of mCPP was the most effective at decreasing rearing behavior, with peak effects 15min after injection. PSD decreased locomotion and rearing behaviors, thereby inhibiting a further impairment induced by mCPP. Plasma concentrations of mCPP were significantly higher in PSD 48h animals compared to the non-PSD control group. Twenty-four hours of RB combined with mCPP administration produced a slight reduction in locomotion. Our results show that mCPP was able to significantly change the behavior of naïve, PSD, and RB mice. When combined with sleep deprivation, there was a higher availability of drug in plasma levels. Taken together, our results suggest that sleep loss can enhance the behavioral effects of the potent psychoactive drug, mCPP, even after a period of rebound sleep.

In this work, all publicly-accessible published findings on Alicyclobacillus acidoterrestris heat resistance in fruit beverages as affected by temperature and pH were compiled. Then, study characteristics (protocols, fruit and variety, °Brix, pH, temperature, heating medium, culture medium, inactivation method, strains, etc.) were extracted from the primary studies, and some of them incorporated to a meta-analysis mixed-effects linear model based on the basic Bigelow equation describing the heat resistance parameters of this bacterium. The model estimated mean D* values (time needed for one log reduction at a temperature of 95 °C and a pH of 3.5) of Alicyclobacillus in beverages of different fruits, two different concentration types, with and without bacteriocins, and with and without clarification. The zT (temperature change needed to cause one log reduction in D-values) estimated by the meta-analysis model were compared to those ('observed' zT values) reported in the primary studies, and in all cases they were within the confidence intervals of the model. The model was capable of predicting the heat resistance parameters of Alicyclobacillus in fruit beverages beyond the types available in the meta-analytical data. It is expected that the compilation of the thermal resistance of Alicyclobacillus in fruit beverages, carried out in this study, will be of utility to food quality managers in the determination or validation of the lethality of their current heat treatment processes.

Lymphoma is the most common head and neck malignancy in children, and palatine tonsils asymmetry is the most frequent clinical manifestation of tonsillar lymphoma. However, several studies with children with tonsillar asymmetry found no case of lymphoma, showing that the relationship of tonsillar asymmetry with lymphoma is unclear. In this review, we aimed to identify the association between tonsillar asymmetry and tonsillar lymphoma in children by conducting systematic reviews of the literature on children with palatine tonsil lymphoma and tonsillar asymmetry. Articles comprising the paediatric age group (up to 18 years) with information concerning clinical manifestations of tonsillar lymphoma or the diagnosis of the tonsillar asymmetry were included. The main cause of asymmetry of palatine tonsils was lymphoid hyperplasia, followed by lymphoma and nonspecific benign changes. The asymmetry of tonsils was present in 73.2% of cases of lymphoma. There was an association between asymmetric palatine tonsils and lymphoma, with a likelihood ratio of 43.5 for children with asymmetry of palatine tonsils and 8938.4 for children with asymmetry of tonsils and other signs of suspicion for malignancy. We also provide recommendations on the management of suspicious cases of palatine tonsil lymphoma.

The parasitic protozoan Leishmania (Leishmania) amazonensis alternates between mammalian and insect hosts. In the insect host, the parasites proliferate as procyclic promastigotes andthen differentiate into metacyclic infective forms. The meta 1 gene is preferentially expressed during metacyclogenesis. Meta 1 expression profile determination along parasite growth curves revealed that the meta 1 mRNA level peaked at the early stationary phase then decreased to an intermediate level. No correlation was observed between meta 1 expression and infectivity. Conversely, infectivity correlated with the increase of apoptotic cells in the late stationary phase.
