Estudio de la viabilidad de la integración de un Sistema de Posicionamiento Óptico en el entorno de la radioterapia intraoperatoria

Actas de: XXIX Congreso Anual de la Sociedad Espñaola de Ingeniería Biomédica (CASEIB 2011). Cáceres, 16-18 Noviembre 2011.La radioterapia intraoperatoria (RIO) es una técnica que combina cirugía y radioterapia, que se aplica en pacientes con tumores para los que se ha indicado su resección y con alto riesgo recidivante. El oncólogo radioterapeuta planifica esta intervención sobre una imagen TAC del paciente. Sin embargo, los datos del escenario real encontrado en la sala de tratamiento (posición y orientación del aplicador respecto del paciente y energía del haz) se deben recoger de forma manual para actualizar la planificación. Esta información es muy valiosa para la documentación y posterior seguimiento del procedimiento realizado. En este trabajo se evalúa la viabilidad de la integración de un sistema de posicionamiento óptico en el entorno RIO, y su precisión para localizar el aplicador sobre la imagen de planificación.Este trabajo ha sido financiado por el Minsiterio de Ciencia e Innovación (PI09/90568 IPT-3000000-2010-3, TEC2010-21619-C04-01), la Comunidad de Madrid (ARTEMIS S2009/DPI-1802) y fondos FEDER.Publicad

Powerscapes

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2012.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (p. 149-151).In 2050, global oil supply will decline to 1/8 of today's. Migrating to the Post-Oil Era, over 10000's km2 of Powerscapes - the solar-collecting infrastructure - will be gradually constructed across the arid desert, for the indispensable production of solar energy to sustain Middle East's economy and global energy supply. The contingency of introducing the Powerscapes is a spatial problem. Unlike a powerplant that burns coal or oil, the scale of the Powerscapes is dramatically extensive. The inserted Powerscapes will interiorize the desert landscape and shelter the ground from the harsh direct sunlight that will be captured for power supply. Transformation in biological development, meteorological activity and geological phenomena will be inevitable, but the change that reduces the heat and evaporation rate will make its climatatic dynamics more habitable for human, animals and plants - an invaluable opportunity for the synthesis of energy production and climate conditioning. This thesis investigates the strategic programming and spatial configuration of such constructed landscape, capitalized by its new temporal characteristics, and sensitively adapting to it. Layers of material will be organized to form "Strata" of temporal conditions to be stretched across the landscape. To forge a symbiotic relationship between Solar Collection, human habitation, agricultural production and wild nature, the layers of material will delineate, push, flip, intersect, puncuate, wrap and merge, responding to programmatic needs and geographical dynamics that the natural geology and the Powerscapes together create. Such adaptive organization also permits certain geometrical and configuration logic to reiterate themselves in multiple scales, formulating a fractalic field with recursive part to whole relationships.by Chun Lun Otto Ng.M.Arch

Pessimism of the modernist intellect versus optimism of the democratic will: The interpretive school of governance

There is a tension between pessimism and optimism running through Mark Bevir's thesis in Democratic Governance. The intellectual apprehension on display is directed, in the main, at the state of the modern democratic polity. Indeed, Bevir's Democratic Governance is characterised by, on the one hand, a pessimistic unease about the condition of today's increasingly fragmented and unaccountable polity. This article examines the chief sources of Bevir's pessimism. These concerns over the present state of democracy are informed by Bevir's theoretical approach to modern democratic processes and institutions. In this respect, Democratic Governance draws upon the Anglo-governance school, associated with political scientists such as Rod Rhodes, Martin Smith, as well as Bevir himself. At the same time, he goes beyond Anglo-governance, offering a more philosophical appreciation of governance. In what I term the Interpretive School of Governance, Bevir conducts an historical anthropology of the cultural imperialism of modernist thinking in the public sphere, of which the pursuit of joined-up governance is one such example. The dominance of modernism, with its faith in positivist empiricism and scientific models, has further augmented the fragmentation, cynicism and democratic alienation surrounding the modern polity. On the other hand, Bevir hankers for an optimistic vision of a democratic tomorrow that is better than today's democracy. The alternative is a form of participatory democracy, which is pluralistic both philosophically and in terms of policy practice. For reasons which are considered, this more optimist vision is sketched out rather than outlined in detail

The Intervention Areas of the Psychologist in Pediatric Palliative Care: A Retrospective Analysis

: Infants, children and adolescents with life-limiting and life-threatening disease need long-term care that may change according to disease's natural history. With the primary goal of quality of life, the psychologist of pediatric palliative care (PPC) network deals with a large variety of issues. Little consideration has been given to the variety of intervention areas of psychology in PPC that concern the whole life span of the patient and family. The PPC network is composed by a multidisciplinary team of palliative care specialists that intervenes at home, in the hospital and in every place where the patient is living. The network coordinates different public health services to respond to clinical, psychosocial and spiritual needs. In these scenarios, the psychological need is not a single event but a moment inserted in the complexity of the child's needs. This retrospective monocentric project consists of an analysis of characteristics of psychological interventions in our PPC service. The time frame taken into consideration is 2019-2020, analyzing the clinical records of 186 patients of Pediatric Palliative Care and Pain Service of Veneto Region (Italy). The areas that emerged in the analysis show how the intervention of the psychologist in PPC does not concern only end-of-life, but a series of topics that are significant for the family to guarantee psycho-social wellbeing oriented toward the best quality of life. In conclusion, these different topics highlight the complexity of the child and family experience. This variety must be taken into consideration, the psychologist must increase holistic support with a dedicated skills curriculum

Enrolling the Citizen in Sustainability: Membership Categorization, Morality and Civic Participation

This article examines the common-sense and methodical ways in which "the citizen" is produced and enrolled as an active participant in "sustainable" regional planning. Using Membership Categorization Analysis, we explicate how the categorization procedures in the Foreword of a draft regional planning policy interactionally produce the identity of "the citizen" and "civic values and obligations" in relation to geographic place and institutional categories. Furthermore, we show how positioning practices establish a relationship between authors (government) and readers (citizens) where both are ascribed with the same moral values and obligations toward the region. Hence, "the citizen" as an active participant in "sustainable" regional planning is viewed as a practical accomplishment that is underpinned by a normative morality associated with the task of producing orderliness in "text-in-interaction.

Protocols for early discharging of premature infants: An empirical assessment on safety and savings

Background Preterm newborns may be discharged when clinical conditions are stable. Several criteria for early discharge have been proposed in the literature. This study carried out the first quantitative comparison of their impact in terms of hospitalization savings, safety and costs. Methods This study was based on the clinical histories of 213 premature infants born in the Neonatal Intensive Care Unit of Padova University Hospital between 2013 and 2014. Seventeen early discharge criteria were drawn from the literature and retrospectively applied to these data, and computation of hospitalization savings, safety and costs implied by each criterion was carried out. Results Among the criteria considered, average gains ranged from 1.1 to 10.3 hospital days and between 0.3 and 1.1 fewer infections per discharged infant. Criteria that led to saving more hospital days had higher cost-effectiveness in terms of crisis and infection, and they spared infants from more infections. However, episodes of apnea and bradycardia were detected after the potential early discharge date for all criteria, with a mean number of episodes numbering between 0.3 and 1.4. Conclusion The results highlight a clear trade-off between days saved and health risks for infants, with potential consequences for health care cost
