Características das Curvas de Regressão da Gonadotrofina Coriônica Pós-mola Hidatiforme Completa

Objetivos: construir a curva de regressão do b-hCG pós-mola hidatiforme completa (MHC) com remissão espontânea e comparar com a curva de regressão pós-MHC com tumor trofoblástico gestacional (TTG). Análise comparativa da curva de regressão do b-hCG das portadoras de MHC, acompanhadas no Serviço, com a curva de regressão observada por outros autores1-3. Métodos: foi realizada avaliação clínica e laboratorial (dosagem sérica de b-hCG), na admissão e no segmento pós-molar, de todas as pacientes com MHC, atendidas entre 1990 e 1998 no Hospital das Clínicas de Botucatu - Unesp. O resultado da determinação seriada do b-hCG foi analisado em curvas log de regressão. A evolução da curva de regressão do b-hCG foi analisada e comparada em MHC com remissão espontânea e MHC com TTG numa curva log de regressão, com intervalo de confiança de 95%. A curva log de regressão do grupo de remissão espontânea foi comparada com curvas consideradas padrão1,2. Foram construídas curvas log individuais de todas as pacientes e classificadas de acordo com os quatro tipos de curva (I, II, III e IV), propostos para o seguimento pós-molar³. Resultados: 61 pacientes com MHC tiveram seguimento pós-molar completo, 50 (82%) apresentaram remissão espontânea e 11 (18%) desenvolveram TTG. No grupo de pacientes com MHC e remissão espontânea, o tempo para alcançar a normalização dos níveis do b-hCG, após o esvaziamento molar, foi até 20 semanas. As pacientes que desenvolveram TTG apresentaram desvio precoce da curva de regressão normal do b-hCG, 4 a 6 semanas após o esvaziamento molar. Nestas pacientes, a quimioterapia foi introduzida em média na 9ª semana pós-esvaziamento molar. Conclusões: a curva de regressão do b-hCG pós-MHC com remissão espontânea apresentou declínio log exponencial, semelhante ao observado por outros autores1,2, e diferente das MHC com TTG. Foram identificados três tipos de curvas de regressão do b-hCG, semelhantes aos de Goldstein³, I, II e IV, e outros dois tipos diferentes de regressão do b-hCG: V (regressão normal) e VI (regressão anormal).

Potential benefits of building information modeling for building material supplier

This thesis investigated building information modeling (BIM) from a material supplier’s point of view. The objective was to gain understanding about how a building material supplier could benefit from the growing use of BIM in the AEC (architectural, engineering and construction) industry. Increasing amount of inquiries related to BIM from customers and other interest groups had awoken target company’s interest towards BIM. This thesis acts as a pre-study for the target company related to potential of BIM. First of all BIM and its meaning from a material supplier’s point of view was defined based on a literature review. To reveal the potential benefits of BIM for a material supplier a questionnaire survey and in total of 11 interviews were conducted. Based on the literature review and analyzed results it came clear that BIM offers benefits also for material suppliers. Product libraries and material databases for BIM tools can act as an important marketing channel for material suppliers. Material suppliers could also utilize the information from the BIM models to schedule their deliveries more precisely and potentially even to schedule their own production. All this needs deeper cooperation between material suppliers, contractors and other stakeholders in the AEC industry. Based on the results also first steps for the target company to utilize the growing use of BIM were defined.

Customer Need Assessment for Differentiation in Building Information Modeling

Building Information Modeling – BIM is widely spreading in the Architecture, Engineering, and Construction (AEC) industries. Manufacturers of building elements are also starting to provide more and more objects of their products. The ideal availability and distribution for these models is not yet stabilized. Usual goal of a manufacturer is to get their model into design as early as possible. Finding the ways to satisfy customer needs with a superior service would help to achieve this goal. This study aims to seek what case company’s customers want out of the model and what they think is the ideal way to obtain these models and what are the desired functionalities for this service. This master’s thesis uses a modified version of lead user method to gain understanding of what the needs are in a longer term. In this framework also benchmarking of current solutions and their common model functions is done. Empirical data is collected with survey and interviews. As a result this thesis provides understanding that what is the information customer uses when obtaining a model, what kind of model is expected to be achieved and how is should the process optimally function. Based on these results ideal service is pointed out.

L’importance de la coopération de TRAF1 et LSP1 en aval du récepteur 4-1BB(CD137) pour la survie des lymphocytes

4-1BB (CD137) est un membre de la superfamille TNFR qui est impliqué dans la transmission des signaux de survie aux lymphocytes. TRAF1 est une protéine adaptatrice qui est recrutée par 4-1BB et autres TNFRs et est caractérisée par une expression très restreinte aux lymphocytes, cellules dendritiques et certaines cellules épithéliales. TRAF1 est nécessaire pour l’expansion et la survie des cellules T mémoire en présence d'agonistes anti-4-1BB in vivo. De plus, TRAF1 est requise en aval de 4-1BB pour activer (phosphoryler) la MAP kinase Erk impliquée dans la régulation de la molécule pro-apoptotique Bim. Suite à l’activation du récepteur 4-1BB, TRAF1 et ERK sont impliqués dans la phosphorylation de Bim et la modulation de son expression. L’activation et la régulation de TRAF1 et Bim ont un rôle important dans la survie des cellules T CD8 mémoires. Dans cette étude, nous avons utilisé une approche protéomique afin de pouvoir identifier de nouveaux partenaires de liaison de TRAF1. Utilisant cette stratégie, nous avons identifié que LSP1 (Leukocyte Specific Protein 1) est recruté dans le complexe de signalisation 4-1BB de manière TRAF1 dépendante. Une caractérisation plus poussée de l’interaction entre TRAF1 et LSP1 a montré que LSP1 lie la région unique N-terminal de TRAF1 de façon indépendante de la région conservée C-terminal. À l’instar des cellules T déficientes en TRAF1, les cellules T déficientes en LSP1 ne sont pas capables d’activer ERK en aval de 4-1BB et par conséquent ne peuvent pas réguler Bim. Ainsi, TRAF1 et LSP1 coopèrent en aval de 4-1BB dans le but d’activer ERK et réguler en aval les niveaux de Bim dans les cellules T CD8. Selon la littérature, le récepteur 4-1BB n’est pas exprimé à la surface des cellules B murines, mais le récepteur 4-1BB favorise la prolifération et la survie des cellules B humaines. Cependant, il est important d'étudier l'expression du récepteur 4-1BB dans les cellules B murines afin de disposer d'un modèle murin et de prédire la réponse clinique à la manipulation de 4-1BB. En utilisant différentes stimulations de cellules B murines primaires, nous avons identifié que le récepteur 4-1BB est exprimé à la surface des cellules B de souris suite à une stimulation avec le LPS (Lipopolysaccharides). Une caractérisation plus poussée a montré que le récepteur 4-1BB est induit dans les cellules B murines d'une manière dépendante de TLR4 (Toll Like Receptor 4). Collectivement, notre travail a démontré que la stimulation avec le LPS induit l’expression du récepteur 4-1BB à la surface des cellules B murines, menant ainsi à l'induction de TRAF1. De plus, TRAF1 et LSP1 coopèrent en aval de 4-1BB pour activer la signalisation de la Map kinase ERK dans les cellules B murines de manière similaire aux cellules T. Les cellules B déficientes en TRAF1 et les cellules B déficientes en LSP1 ne sont pas en mesure d'activer la voie ERK en aval de 4-1BB et montrent un niveau d’expression du récepteur significativement diminué comparé aux cellules B d’une souris WT. Ainsi, TRAF1 et LSP1 sont nécessaires pour une expression maximale du récepteur 4-1BB à la surface cellulaire de cellules B murines et coopèrent en aval de 4-1BB afin d'activer la cascade ERK dans les cellules B murines.

Imaginarios, biomedicina y normatividad: una respuesta a los procesos de estigmatización y discriminación por VIH

El tratamiento del VIH/sida, como problemática que ocupa a la salud colectiva, requiere nuevas perspectivas teóricas para su análisis. Objetivo: reconstruir algunas matrices imaginarias, configu- radoras de la infección de VIH, vinculadas con prácticas normativas y con la formación del saber clínico, visibilizar consecuencias de estos procesos y articular estas matrices con las problemáticas de discriminación y estigmatización que pesan sobre el diagnóstico. Materiales y métodos: se efectuaron entrevistas en profundidad a jóvenes entre 18 y 35 años y a profesionales de la salud dedicados al tratamiento del VIH/sida de hospitales públicos de las ciudades de Santa Fe y Paraná (Argentina). Resultados: el discurso biomédico –nodal en tanto exigencia de la norma y garante del ejercicio de normalización de los individuos y de las poblaciones a partir del binomio normal/ patológico– incide en la apropiación de la diagnosis y la convivencia con la infección. Conclusión: a partir de los resultados, es posible comprender los procesos de estigmatización y discrimina- ción como mecanismos privilegiados de estas instancias normativas que median la configuración discursiva del VIH. A su vez, se advierte que el rechazo prevalente en jóvenes a realizarse las pruebas diagnósticas, como las dificultades de acceso a los servicios de salud, es consecuencia de los procesos indicados.

Convergencia de vías de señalización en un modelo de apoptosis

La sepsis es un evento inflamatorio generalizado del organismo inducido por un daño causado generalmente por un agente infeccioso. El patógeno más frecuentemente asociado con esta entidad es el Staphylococcus aureus, responsable de la inducción de apoptosis en células endoteliales debida a la producción de ceramida. Se ha descrito el efecto protector de la proteína C activada (PCA) en sepsis y su relación con la disminución de la apoptosis de las células endoteliales. En este trabajo se analizó la activación de las quinasas AKT, ASK1, SAPK/JNK y p38 en un modelo de apoptosis endotelial usando las técnicas de Western Blotting y ELISA. Las células endoteliales (EA.hy926), se trataron con C2-ceramida (130μM) en presencia de inhibidores químicos de cada una de estas quinasas y PCA. La supervivencia de las células en presencia de inhibidores químicos y PCA fue evaluada por medio de ensayos de activación de las caspasas 3, 7 y 9, que verificaban la muerte celular por apoptosis. Los resultados evidencian que la ceramida reduce la activación de AKT y aumenta la activación de las quinasas ASK, SAPK/JNK y p38, en tanto que PCA ejerce el efecto contrario. Adicionalmente se encontró que la tiorredoxina incrementa la activación/fosforilación de AKT, mientras que la quinasa p38 induce la defosforilación de AKT.

The right to remain silent : the ethics of invasion and evasion in Paul Sayer’s ''The Comforts of Madness''

Este artigo considera as implicações do silêncio e da ética da experimentação médica no romance de Paul Sayer, The Comforts of Madness, vencedor do prémio Whitbread. O romance de Sayer debruça-se sobre um paciente emestado catatónico, Peter, o qual procura retirar-se para um estado de pura subjetividade como consequência de uma série de eventos traumáticos. Inicialmente tratado num hospital tradicional, é posteriormente transferido para uma clínica experimental onde é submetido a uma série de «tratamento» invasivos e bárbaros com o objectivo de «curá-lo». A abordagem de Sayer dos temas relacionados com a insanidade, o silêncio pessoal e a medicina progressiva levanta questões relativas ao direito do indivíduo de rejeitar o mundo comunitário e à ética de extrair a narrativa retida da narrativa relutante. Ao examinar os processos de normalização e resistência, o romance levanta questões relativamente à ética da inclusão forçada e estabelece uma legitimidade de não-cooperação, o direito ao silêncio, o qual funciona em paralelo com a legitimidade da voz marginalizada. A tendência recente nos estudos literários tem sido no sentido da exposição e promoção das vozes anteriormente ostracizadas pela indústria editorial e pelo público leitor, mas, de um modo geral, este processo tem partido da premissa de que a voz perdida beneficia de tal exposição. Para Sayer, existe o caso igualmente persuasivo relacionado com o reconhecimento do direito à privacidade, em risco de ser preterido numa era de transparência excessiva. Este ensaio discute o modo como o romance de Sayer aborda estas preocupações e salienta a sua consciência do processo complexo de lidar com o indivíduo para quem a recusa a falar corresponde a um gesto social ambíguo.

Síndrome de Down : educação diferenciada

A Síndrome de Down é uma problemática com alta incidência na nossa sociedade e possui características muito específicas que variam de indivíduo para indivíduo. A educação de uma criança com Trissomia 21 deve ter a mesma finalidade da educação de qualquer outra, ou seja, é necessário dar-lhe todas as oportunidades e todo o apoio necessário para que possa desenvolver as suas faculdades cognitivas e sociais até ao máximo que lhe for possível. Esta é uma das bases da educação das crianças com esta patologia consideradas fundamentais, assim como, o princípio de normalização que tem como objetivo possibilitar a estas crianças uma vivência igual ou semelhante a qualquer outro indivíduo da sociedade. Proponho, neste trabalho, a apresentação ao leitor de um conhecimento mais profundo sobre o processo de integração das crianças com Síndrome de Down em turmas do Ensino Regular, sobre o desenvolvimento destes alunos, as suas capacidades e limitações, abordando também algumas razões para a inclusão destes alunos nas escolas, de forma a facultar-lhes um processo de ensino/aprendizagem na verdadeira ascensão da palavra. Considero que este conhecimento é de extrema importância não só para professores e educadores, mas também para familiares, que, assim, poderão estimular adequadamente a criança, proporcionando-lhe um desenvolvimento adequado. Neste estudo, é meu intuito também evidenciar estratégias na educação de crianças com Síndrome de Down, estratégias essas que facilitarão a prática pedagógica e consequente futuro das crianças afetadas por esta problemática.

Requirements for building information modeling based lean production management systems for construction

Smooth flow of production in construction is hampered by disparity between individual trade teams' goals and the goals of stable production flow for the project as a whole. This is exacerbated by the difficulty of visualizing the flow of work in a construction project. While the addresses some of the issues in Building information modeling provides a powerful platform for visualizing work flow in control systems that also enable pull flow and deeper collaboration between teams on and off site. The requirements for implementation of a BIM-enabled pull flow construction management software system based on the Last Planner System™, called ‘KanBIM’, have been specified, and a set of functional mock-ups of the proposed system has been implemented and evaluated in a series of three focus group workshops. The requirements cover the areas of maintenance of work flow stability, enabling negotiation and commitment between teams, lean production planning with sophisticated pull flow control, and effective communication and visualization of flow. The evaluation results show that the system holds the potential to improve work flow and reduce waste by providing both process and product visualization at the work face.

Towards a holistic modelling framework for embodied carbon and waste in the building lifecycle

As the building industry proceeds in the direction of low impact buildings, research attention is being drawn towards the reduction of carbon dioxide emission and waste. Starting from design and construction to operation and demolition, various building materials are used throughout the whole building lifecycle involving significant energy consumption and waste generation. Building Information Modelling (BIM) is emerging as a tool that can support holistic design-decision making for reducing embodied carbon and waste production in the building lifecycle. This study aims to establish a framework for assessing embodied carbon and waste underpinned by BIM technology. On the basis of current research review, the framework is considered to include functional modules for embodied carbon computation. There are a module for waste estimation, a knowledge-base of construction and demolition methods, a repository of building components information, and an inventory of construction materials’ energy and carbon. Through both static 3D model visualisation and dynamic modelling supported by the framework, embodied energy (carbon), waste and associated costs can be analysed in the boundary of cradle-to-gate, construction, operation, and demolition. The proposed holistic modelling framework provides a possibility to analyse embodied carbon and waste from different building lifecycle perspectives including associated costs. It brings together existing segmented embodied carbon and waste estimation into a unified model, so that interactions between various parameters through the different building lifecycle phases can be better understood. Thus, it can improve design-decision support for optimal low impact building development. The applicability of this framework is anticipated being developed and tested on industrial projects in the near future.

Model-based life cycle cost and assessment tool for sustainable building design decision

There is a growing concern in reducing greenhouse gas emissions all over the world. The U.K. has set 34% target reduction of emission before 2020 and 80% before 2050 compared to 1990 recently in Post Copenhagen Report on Climate Change. In practise, Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) tools have been introduced to construction industry in order to achieve this such as. However, there is clear a disconnection between costs and environmental impacts over the life cycle of a built asset when using these two tools. Besides, the changes in Information and Communication Technologies (ICTs) lead to a change in the way information is represented, in particular, information is being fed more easily and distributed more quickly to different stakeholders by the use of tool such as the Building Information Modelling (BIM), with little consideration on incorporating LCC and LCA and their maximised usage within the BIM environment. The aim of this paper is to propose the development of a model-based LCC and LCA tool in order to provide sustainable building design decisions for clients, architects and quantity surveyors, by then an optimal investment decision can be made by studying the trade-off between costs and environmental impacts. An application framework is also proposed finally as the future work that shows how the proposed model can be incorporated into the BIM environment in practise.

Design and management of sustainable built environments

The United Nation Intergovernmental Panel on Climate Change (IPCC) makes it clear that climate change is due to human activities and it recognises buildings as a distinct sector among the seven analysed in its 2007 Fourth Assessment Report. Global concerns have escalated regarding carbon emissions and sustainability in the built environment. The built environment is a human-made setting to accommodate human activities, including building and transport, which covers an interdisciplinary field addressing design, construction, operation and management. Specifically, Sustainable Buildings are expected to achieve high performance throughout the life-cycle of siting, design, construction, operation, maintenance and demolition, in the following areas: • energy and resource efficiency; • cost effectiveness; • minimisation of emissions that negatively impact global warming, indoor air quality and acid rain; • minimisation of waste discharges; and • maximisation of fulfilling the requirements of occupants’ health and wellbeing. Professionals in the built environment sector, for example, urban planners, architects, building scientists, engineers, facilities managers, performance assessors and policy makers, will play a significant role in delivering a sustainable built environment. Delivering a sustainable built environment needs an integrated approach and so it is essential for built environment professionals to have interdisciplinary knowledge in building design and management . Building and urban designers need to have a good understanding of the planning, design and management of the buildings in terms of low carbon and energy efficiency. There are a limited number of traditional engineers who know how to design environmental systems (services engineer) in great detail. Yet there is a very large market for technologists with multi-disciplinary skills who are able to identify the need for, envision and manage the deployment of a wide range of sustainable technologies, both passive (architectural) and active (engineering system),, and select the appropriate approach. Employers seek applicants with skills in analysis, decision-making/assessment, computer simulation and project implementation. An integrated approach is expected in practice, which encourages built environment professionals to think ‘out of the box’ and learn to analyse real problems using the most relevant approach, irrespective of discipline. The Design and Management of Sustainable Built Environment book aims to produce readers able to apply fundamental scientific research to solve real-world problems in the general area of sustainability in the built environment. The book contains twenty chapters covering climate change and sustainability, urban design and assessment (planning, travel systems, urban environment), urban management (drainage and waste), buildings (indoor environment, architectural design and renewable energy), simulation techniques (energy and airflow), management (end-user behaviour, facilities and information), assessment (materials and tools), procurement, and cases studies ( BRE Science Park). Chapters one and two present general global issues of climate change and sustainability in the built environment. Chapter one illustrates that applying the concepts of sustainability to the urban environment (buildings, infrastructure, transport) raises some key issues for tackling climate change, resource depletion and energy supply. Buildings, and the way we operate them, play a vital role in tackling global greenhouse gas emissions. Holistic thinking and an integrated approach in delivering a sustainable built environment is highlighted. Chapter two demonstrates the important role that buildings (their services and appliances) and building energy policies play in this area. Substantial investment is required to implement such policies, much of which will earn a good return. Chapters three and four discuss urban planning and transport. Chapter three stresses the importance of using modelling techniques at the early stage for strategic master-planning of a new development and a retrofit programme. A general framework for sustainable urban-scale master planning is introduced. This chapter also addressed the needs for the development of a more holistic and pragmatic view of how the built environment performs, , in order to produce tools to help design for a higher level of sustainability and, in particular, how people plan, design and use it. Chapter four discusses microcirculation, which is an emerging and challenging area which relates to changing travel behaviour in the quest for urban sustainability. The chapter outlines the main drivers for travel behaviour and choices, the workings of the transport system and its interaction with urban land use. It also covers the new approach to managing urban traffic to maximise economic, social and environmental benefits. Chapters five and six present topics related to urban microclimates including thermal and acoustic issues. Chapter five discusses urban microclimates and urban heat island, as well as the interrelationship of urban design (urban forms and textures) with energy consumption and urban thermal comfort. It introduces models that can be used to analyse microclimates for a careful and considered approach for planning sustainable cities. Chapter six discusses urban acoustics, focusing on urban noise evaluation and mitigation. Various prediction and simulation methods for sound propagation in micro-scale urban areas, as well as techniques for large scale urban noise-mapping, are presented. Chapters seven and eight discuss urban drainage and waste management. The growing demand for housing and commercial developments in the 21st century, as well as the environmental pressure caused by climate change, has increased the focus on sustainable urban drainage systems (SUDS). Chapter seven discusses the SUDS concept which is an integrated approach to surface water management. It takes into consideration quality, quantity and amenity aspects to provide a more pleasant habitat for people as well as increasing the biodiversity value of the local environment. Chapter eight discusses the main issues in urban waste management. It points out that population increases, land use pressures, technical and socio-economic influences have become inextricably interwoven and how ensuring a safe means of dealing with humanity’s waste becomes more challenging. Sustainable building design needs to consider healthy indoor environments, minimising energy for heating, cooling and lighting, and maximising the utilisation of renewable energy. Chapter nine considers how people respond to the physical environment and how that is used in the design of indoor environments. It considers environmental components such as thermal, acoustic, visual, air quality and vibration and their interaction and integration. Chapter ten introduces the concept of passive building design and its relevant strategies, including passive solar heating, shading, natural ventilation, daylighting and thermal mass, in order to minimise heating and cooling load as well as energy consumption for artificial lighting. Chapter eleven discusses the growing importance of integrating Renewable Energy Technologies (RETs) into buildings, the range of technologies currently available and what to consider during technology selection processes in order to minimise carbon emissions from burning fossil fuels. The chapter draws to a close by highlighting the issues concerning system design and the need for careful integration and management of RETs once installed; and for home owners and operators to understand the characteristics of the technology in their building. Computer simulation tools play a significant role in sustainable building design because, as the modern built environment design (building and systems) becomes more complex, it requires tools to assist in the design process. Chapter twelve gives an overview of the primary benefits and users of simulation programs, the role of simulation in the construction process and examines the validity and interpretation of simulation results. Chapter thirteen particularly focuses on the Computational Fluid Dynamics (CFD) simulation method used for optimisation and performance assessment of technologies and solutions for sustainable building design and its application through a series of cases studies. People and building performance are intimately linked. A better understanding of occupants’ interaction with the indoor environment is essential to building energy and facilities management. Chapter fourteen focuses on the issue of occupant behaviour; principally, its impact, and the influence of building performance on them. Chapter fifteen explores the discipline of facilities management and the contribution that this emerging profession makes to securing sustainable building performance. The chapter highlights a much greater diversity of opportunities in sustainable building design that extends well into the operational life. Chapter sixteen reviews the concepts of modelling information flows and the use of Building Information Modelling (BIM), describing these techniques and how these aspects of information management can help drive sustainability. An explanation is offered concerning why information management is the key to ‘life-cycle’ thinking in sustainable building and construction. Measurement of building performance and sustainability is a key issue in delivering a sustainable built environment. Chapter seventeen identifies the means by which construction materials can be evaluated with respect to their sustainability. It identifies the key issues that impact the sustainability of construction materials and the methodologies commonly used to assess them. Chapter eighteen focuses on the topics of green building assessment, green building materials, sustainable construction and operation. Commonly-used assessment tools such as BRE Environmental Assessment Method (BREEAM), Leadership in Energy and Environmental Design ( LEED) and others are introduced. Chapter nineteen discusses sustainable procurement which is one of the areas to have naturally emerged from the overall sustainable development agenda. It aims to ensure that current use of resources does not compromise the ability of future generations to meet their own needs. Chapter twenty is a best-practice exemplar - the BRE Innovation Park which features a number of demonstration buildings that have been built to the UK Government’s Code for Sustainable Homes. It showcases the very latest innovative methods of construction, and cutting edge technology for sustainable buildings. In summary, Design and Management of Sustainable Built Environment book is the result of co-operation and dedication of individual chapter authors. We hope readers benefit from gaining a broad interdisciplinary knowledge of design and management in the built environment in the context of sustainability. We believe that the knowledge and insights of our academics and professional colleagues from different institutions and disciplines illuminate a way of delivering sustainable built environment through holistic integrated design and management approaches. Last, but not least, I would like to take this opportunity to thank all the chapter authors for their contribution. I would like to thank David Lim for his assistance in the editorial work and proofreading.

Changing building user attitude and organisational policy towards sustainable resource use in healthcare

Health care provision is significantly impacted by the ability of the health providers to engineer a viable healthcare space to support care stakeholders needs. In this paper we discuss and propose use of organisational semiotics as a set of methods to link stakeholders to systems, which allows us to capture clinician activity, information transfer, and building use; which in tern allows us to define the value of specific systems in the care environment to specific stakeholders and the dependence between systems in a care space. We suggest use of a semantically enhanced building information model (BIM) to support the linking of clinician activity to the physical resource objects and space; and facilitate the capture of quantifiable data, over time, concerning resource use by key stakeholders. Finally we argue for the inclusion of appropriate stakeholder feedback and persuasive mechanism, to incentivise building user behaviour to support organisational level sustainability policy.

Service oriented approach to facility management using extended building information modelling

Facility management (FM), from a service oriented approach, addresses the functions and requirements of different services such as energy management, space planning and security service. Different service requires different information to meet the needs arising from the service. Object-based Building Information Modelling (BIM) is limited to support FM services; though this technology is able to generate 3D models that semantically represent facility’s information dynamically over the lifecycle of a building. This paper presents a semiotics-inspired framework to extend BIM from a service-oriented perspective. The extended BIM, which specifies FM services and required information, will be able to express building service information in the right format for the right purposes. The service oriented approach concerns pragmatic aspect of building’s information beyond semantic level. The pragmatics defines and provides context for utilisation of building’s information. Semiotics theory adopted in this paper is to address pragmatic issues of utilisation of BIM for FM services.
