A review of tertiary BIM education for advanced engineering communication with visualization

SPECT with Tc-99m-labeled agents is better able to detect viability after nitrate administration. Nitrates induce vasoclilation and may increase blood flow to severely hypoperfused but viable myocardium, thereby enhancing tracer delivery and improving the detection of viability. Quantitative data on the changes in blood flow are lacking in SPECT but can be provided by PET. The aim of the present study was to use PET to evaluate whether nitrate administration increases blood flow to chronically dysfunctional but viable myocardium. Methods: N-13-Ammonia PET was used to quantitatively assess blood flow, and F-18-FDG PET was used as the gold standard to detect viable myocardium. Twenty-five patients with chronic ischemic left ventricular dysfunction underwent N-13-ammonia PET at rest and after nitrate administration. Results: A significant increase in nitrate-enhanced blood flow was observed in viable segments (from 0.55 +/- 0.15 to 0.68 +/- 0.24 mL/min/g, P <0.05). No statistically significant change in blood flow was observed in nonviable segments (0.60 +/- 0.20 vs. 0.55 +/- 0.18 mL/min/g). A ratio of at least 1.1 for nitrate-enhanced flow to resting flow allowed optimal detection of viable myocardium, yielding a sensitivity of 82% with a specificity of 100%. Conclusion: N-13-Ammonia PET showed a significant increase in nitrate-enhanced blood flow in viable myocardium, whereas blood flow remained unchanged after nitrate administration in nonviable myocardium. Nitrate use during myocardial perfusion imaging will lead to improved assessment of myocardial viability

O ensino de BIM no Brasil: onde estamos?

A modelagem da Informação da Construção (Building Information Modeling - BIM) envolve um conjunto interrelacionado de políticas, processos e tecnologias para gerenciar a essência do projeto, construção e operação de edifícios no formato digital em todo o ciclo de vida da edificação. Entender BIM apenas como tecnologia é uma distorção advinda de uma simplificação extrema do paradigma. Dessa forma, a abordagem de BIM no ensino deve ir além da capacitação instrumental contida nas disciplinas de informática aplicada. Este artigo apresenta um diagnóstico de experiências brasileiras e internacionais de ensino de BIM, o que permite avaliar a abrangência dos esforços de ensino adotados até o presente no Brasil, neste contexto. Este diagnóstico se dá por meio de revisão bibliográfica sobre relatos de experiência de ensino de BIM, discussão em workshop e experimentação no ensino. Classificam-se as experiências avaliadas identificando-se os estágios de adoção de BIM e os níveis de competência por elas fomentados. Ao utilizar uma mesma classificação aplicada no estudo do cenário internacional para as experiências nacionais, foi possível balizar o nível de desenvolvimento do ensino de BIM no Brasil. Discute-se, à luz das experiências apresentadas, o quão abrangente deve ser a formação em BIM e a quais estágios de adoção de BIM essas experiências de ensino conduzem. Modelos de inspiração que possam contribuir com o cenário brasileiro de adoção do BIM são apresentados, extraídos de boas experiências estrangeiras

Multidisciplinary AEC Education Utilising BIM/PLIM Tools and Processes

© IFIP International Federation for Information Processing 2013. The construction industry worldwide is moving towards more collaborative working practices, aided by building information modelling (BIM) tools and processes. BIM could be more accurately described as Project Lifecycle Information Management (PLIM). Many firms are claiming to be ‘doing BIM’, but are just scraping the surface in terms of the benefits that can be leveraged from true integrated, collaborative design and construction. New graduates, trained in collaboration and PLIM techniques will be the best people to drive positive change, but current educational models do not tend to provide these skills. This paper describes current worldwide educational trends in collaborative multidisciplinary education, and a proposed framework to assist academics in implementing changes to AEC curricula
