Debido a la obligatoriedad e importancia de identificar los riesgos psicosociales en las empresas colombianas, se aplicará el instrumento validado en Colombia y la Pontificia Universidad Javeriana (2010) a los colaboradores de la organización Cintalast SAS, empresa del sector textil, un sector con gran impacto en la industria y con condiciones laborales importantes para los trabajadores. Se realizará la ponderación de los resultados de factores intralaborales, extralaborales y de estrés laboral a nivel general y por las formas A y B. Por último, se propone según los niveles encontrados de los factores de riesgo psicosocial establecer propuesta de acciones de intervención, promoción y/o prevención. Due to the obligation and importance of identifying psychosocial risks in Colombian companies, the instrument validated in Colombia and the Pontificia Universidad Javeriana (2010) will be applied to the collaborators of the organization Cintalast SAS, a company in the textile sector, a sector with great impact. in industry and with important working conditions for workers. The weighting of the results of intra-work factors, extra-work factors and work stress will be carried out at a general level and by forms A and B. Finally, according to the levels found of the psychosocial risk factors, it is proposed to establish a proposal for intervention, promotion and/or prevention actions.

This paper presents a corpus-based analysis of printed eco-friendly car advertisements in English in line with the growing consumer interest in environmental issues and the development of green advertising. The aim of the research is threefold: 1) to unveil the content cognitive operations (for the purpose of this research, metonymy, metonymic chain, metaphoric amalgam and metaphor) underlying the ads and their modes of representation; 2) to examine the relationship between (i) these conceptual operations and the environmental claims made by advertisers, and (ii) the environmental claims made by advertisers and the text-image interaction. In this light, the paper yields two major findings: a) the cognitive operations underlying our corpus are usually rendered in the visual and verbal modes; b) the environmental claims underlying the ads correlate with the conceptual content and the text-image interplay. The conscious use of these mechanisms by advertisers can help the manner in which messages are interpreted.

"Research has shown that language and culture are closely related (e.g., Brown, 2007; Kramsch, 1998; Kuang, 2007; Savignon & Sysoyev, 2005) and are best acquired together (Schulz, 2007). This paper aims to demonstrate how project-based learning (PBL), one of the main innovative approaches in the current educational landscape, can be useful for teaching culture in the English language classroom at the tertiary educational level. PBL is a teaching approach in which students gain knowledge and skills by working for an extended period of time to investigate and respond to an authentic, engaging, and complex question, problem, or challenge (Kingston, 2018). According to different studies in the field (Kavlu, 2017), this approach can be more engaging and motivating for English language learners than traditional methods. First, the language is being used for an authentic purpose, which gives the language relevance. Further, learners develop content knowledge as well as critical thinking, creative thinking and communication skills. This study will focus on the implementation of PBL in the English language classroom in different degree programs: Primary Education, Infant Education, Hispanic Philology and Humanities. Students created an authentic final product that explored cultural aspects of English-speaking countries in combination with different subjects such as geography, history, literature and economy. The findings are based on a questionnaire that measures tertiary students’ motivation levels and expectations in relation to this pedagogical framework."

The association between the indoor environment and lifetime prevalence of otitis media (OM) in Australian children was assessed. We analysed data from a cross-sectional study of children, aged 7–11 years, performed in twelve Australian cities during 2007–2008. The main outcome was a parental report of their child’s diagnosis with OM by a doctor. Information on the indoor environment (energy sources used for heating, cooling, and cooking, pets, and second-hand smoke exposure), in the first year of life and at present, was collected from parents by a questionnaire. Multi-level logistic regression models were used to adjust for individual- and area-level confounders. Our analysis comprised 2872 children (51% female, mean age: 10.0 (SD 1.2)). Of those, 1097 (39%) were reported to have OM. Exposure to gas heating in the first year of life was significantly associated with higher odds of OM in adjusted models (OR:1.22; 95% CI: 1.00,1.47), as was current exposure to reverse-cycle air conditioning (OR: 1.52, 95% CI: 1.27,1.82). Ownership of a cat or dog at any time was also associated with high odds of OM (OR: 1.50; 95% CI: 1.17,1.92). No other significant associations were observed. In this national study of Australian children, indoor environmental exposures associated with the lifetime prevalence of OM were gas heating, reverse-cycle air conditioning and pet ownership. Exposures in both early life and later childhood may both play a role in OM.

El revisar un paciente en odontopediatría con hematomas y hemorragias es frecuente. El diagnóstico y el tratamiento dependen del conocimiento de los mecanismos normales de la hemostasia y de los laboratorios que los analizan1. Las manipulaciones en la cavidad bucal, máxime aquellas con extravasación de sangre, son un riesgo para los pacientes con trastornos de la coagulación, la prevención es la forma de evitar complicaciones, para ello debe disponer: de una historia clínica con énfasis en antecedentes personales y familiares de problemas hemorrágicos y del conocimiento de las patologías más frecuentes que lo originan así como su manejo2. Las hemorragias menores, son por factores locales, las graves por trastornos sistémicos de la hemostasia, como las coagulopatias congénitas2, grupo heterogéneo de enfermedades secundarias a alteraciones de las proteínas plasmáticas de la hemostasia primaria (ejemplo factor de von Willebrand), de la coagulación o de la fibrinólisis, defecto de un factor o combinación de 2 o más. Esta revisión se propone responder a estas interrogantes.

Introducción. Las cardiopatías congénitas son las malformaciones más habituales en el desarrollo de los niños los cuales, además, son susceptibles a desarrollar infecciones sistémicas microbianas secundarias a infecciones locales polimicrobianas como consecuencia de procedimientos dentales invasivos o toman fármacos, por ejemplo anti-coagulantes, antiarrítmicos, u otros, que pueden interferir con el manejo odontológico. Objetivo. Proponer un protocolo de manejo odontológico que permita detectar las cardiopatías congénitas o ya identificadas tener un abordaje dental que disminuya el riesgo de sepsis o endocarditis para el paciente pediátrico. Método. Revisión de la literatura a través de artículos indexados en Cochrane, Medline, Lilacs, EMBASE, Amedeo y SciELO, enfatizando los últimos cinco años, en los idiomas: francés, italiano, portugués, inglés y español. Resultados. Se presenta un protocolo odonde abordaje odontológico que disminuya los factores de riesgo ante la presencia de cardiopatías congénitas. Conclusión. Ya que existe una au-sencia de información sobre la relación de las cardiopatías congénitas y la odontología infantil, por ello la importancia de contar con un protocolo para el tratamiento de pacientes pediátricos mejorando su atención, pronóstico, calidad de vida y disminuyendo los factores de riesgo ante procedimientos dentales invasivos.

La investigación en el área de ingeniería es un tema complejo al momento de ser abordado en un programa educativo, dado los ambientes de colaboración y sinergias que deben adoptar los alumnos y profesores para el mejor seguimiento de los estudiantes y para una comunicación técnica entre ambos. Esta situación es presentada en este artículo, el cual se enfoca en el programa de estudio de ingeniería en Informática de la Universidad Politécnica del Estado de Morelos, específicamente con dos asignaturas (Estancia I y Estancia II) en las cuales existe un proceso de registro de proyectos de investigación y asignación de asesores para el acompañamiento del alumno en el desarrollo del protocolo de investigación, su implementación y validación de los resultados. Por ende, en este trabajo se propone el desarrollo de una plataforma digital para dar seguimiento a los proyectos de investigación de las mencionadas cátedras.

Most studies of long-term air pollution exposure and children's respiratory health have been performed in urban locations with moderate pollution levels. We assessed the effect of outdoor nitrogen dioxide (NO2), as a proxy for urban air pollution, on current asthma and lung function in Australia, a low-pollution setting.We undertook a national population-based cross-sectional study of children aged 7–11 years living in 12 Australian cities. We collected information on asthma symptoms from parents via questionnaire and measured children's lung function (forced expiratory volume in 1 s [FEV1], forced vital capacity [FVC]) and fractional exhaled nitric oxide [FeNO]). We estimated recent NO2 exposure (last 12 months) using monitors near each child's school, and used a satellite-based land-use regression (LUR) model to estimate NO2 at each child's school and home.Our analysis comprised 2630 children, among whom the prevalence of current asthma was 14.9%. Mean (±SD) NO2 exposure was 8.8 ppb (±3.2) and 8.8 ppb (±2.3) for monitor- and LUR-based estimates, respectively. Mean percent predicted post-bronchodilator FEV1 and FVC were 101.7% (±10.5) and 98.8% (±10.5), respectively. The geometric mean FeNO concentration was 9.4 ppb (±7.1).An IQR increase in NO2 (4.0 ppb) was significantly associated with increased odds of having current asthma; odds ratios (ORs) were 1.24 (95% CI: 1.08, 1.43) and 1.54 (95% CI: 1.26, 1.87) for monitor- and LUR-based estimates, respectively. Increased NO2 exposure was significantly associated with decreased percent predicted FEV1 (−1.35 percentage points [95% CI: −2.21, −0.49]) and FVC (−1.19 percentage points [95% CI: −2.04, −0.35], and an increase in FeNO of 71% (95% CI: 38%, 112%).Exposure to outdoor NO2 was associated with adverse respiratory health effects in this population-based sample of Australian children. The relatively low NO2 levels at which these effects were observed highlight the potential benefits of continuous exposure reduction.

Mosquito-borne viruses are emerging or re-emerging globally, afflicting millions of people around the world. Aedes aegypti, the yellow fever mosquito, is the principal vector of dengue, Zika, and chikungunya viruses, and has well-established populations across tropical and subtropical urban areas of the Americas, including the southern United States. While intense arboviral epidemics have occurred in Mexico and further south in the Americas, local transmission in the United States has been minimal. Here, we study Ae. aegypti and Culex quinquefasciatus host feeding patterns and vertebrate host communities in residential environments of South Texas to identify host-utilization relative to availability. Only 31% of Ae. aegypti blood meals were derived from humans, while 50% were from dogs and 19% from other wild and domestic animals. In Cx. quinquefasciatus, 67% of blood meals were derived from chicken, 22% came from dogs, 9% from various wild avian species, and 2% from other mammals including one human, one cat, and one pig. We developed a model for the reproductive number, R0, for Zika virus (ZIKV) in South Texas relative to northern Mexico using human disease data from Tamaulipas, Mexico. We show that ZIKV R0 in South Texas communities could be greater than one if the risk of human exposure to Ae. aegypti bites in these communities is at least 60% that of Northern Mexico communities. The high utilization of non-human vertebrates and low risk of human exposure in South Texas diminishes the outbreak potential for human-amplified urban arboviruses transmitted by Ae. aegypti.
