Exploração e análise das novas interfaces digitais relacionadas à representação gráfica na arquitetura

Este trabalho integra as pesquisas desenvolvidas pelo Grupo N.elac – IAU.USP, que tem como tema estudos sobre a representação da arquitetura e da cidade. Este artigo faz análise dos novos recursos tecnológicos direcionados para o desenho e projeto arquitetônico que emulam ou fazem uso do movimento gestual humano no ato de desenho e projeto. A pesquisa testa e avalia qualitativamente o uso das novas ferramentas digitais, tais como as tablets gráficas (ex:Apple Ipad), tablets opacas (ex: Wacom Bamboo) e canetas eletrônicas (ex: Wacom Inkling) na execução de desenhos livre e de observação, orientados por uma proposta de desenvolvimento gráfico relacionados ao ato de projeto arquitetônico, de maneira que se possa construir uma análise comparativa e interpretativa por meio dos produtos gerados nesse processo.

Estudo comparativo entre as novas ferramentas digitais utilizadas no desenho à mão livre

This paper makes an analysis on the new technological resources related to architectural drawing that make use of the hand drawing. It tests and evaluates the use of new tools such as tablets (e.g. Wacom Bamboo), graphic tablets (e.g. iPad), tablet/screen hybrids (e.g. Wacom Cintiq) and electronic pens (e.g. Wacom Inkling) in the making of free drawings oriented for the developing of graphic products related to the projective act in architecture and design. The paper makes a comparative e interpretative analysis through the reading of those products.

Jämställd Socialtjänst II – En undersökning av jämställdhet ur brukarperspektiv inom socialtjänsten

Vårt syfte har varit att undersöka jämställdheten inom socialtjänsten, i en norrländsk glesbygdskommun och en mellanstor stadskommun. Uppsatsen består av två studier där del 1 är kvantitativ och behandlar individ- och familjeomsorgens beslut år 2004, och där del 2 är kvalitativ och består av uppföljande intervjuer. Resultaten i del 1 redovisades utifrån, av oss, sammanställd statistik som analyserades med hjälp av tidigare forskning och de valda teoretiska begreppen, det vill säga jämställdhet, genus och social konstruktivism. Resultatet visade att insatser för barn och unga skiljer sig åt för pojkar och flickor i frivillighet kontra tvång. I besluten gällande vuxna missbrukare konstaterade vi en markant skillnad mellan könen både i det totala antalet aktuella individer samt i den procentuella könsfördelningen i varje beslut om åtgärd. Resultaten inom ekonomiskt bistånd visar att kvinnor med barn och män utan barn utgör den övervägande delen av biståndstagarna. Del 2 behandlar intervjuer från tre socialsekreterare. Resultaten visar att socialtjänsten vidmakthåller traditionella uppfattningar om kön, och att jämställdhet ofta ställs mot SoL:s individuella bedömning, där könet ej ska påverka besluten. Uppsatsen är inte generaliserbar då den endast behandlar beslut från två utvalda kommuner på lokal nivå.

Progettazione di un sistema per patient-reported outcome utilizzabile anche su dispositivi mobili

In questo elaborato prenderemo in esame la questione della progettazione di un sistema software atto a gestire alcuni dei problemi legati alla raccolta dei dati in ambito medico. Da tempo infatti si è capita l'importanza di una speciale tecnica di raccolta dei dati clinici, nota in letteratura col nome di "patient-reported outcome", che prevede che siano i pazienti stessi a fornire le informazioni circa l'andamento di una cura, di un test clinico o, più semplicemente, informazioni sul loro stato di salute fisica o mentale. Vedremo in questa trattazione come ciò sia possibile e, soprattutto, come le tecniche e le tecnologie informatiche possano dare un grande contributo ai problemi di questo ambito. Mostreremo non solo come sia conveniente l'uso, in campo clinico, di tecniche automatiche di raccolta dei dati, della loro manipolazione, aggregazione e condivisione, ma anche come sia possibile realizzare un sistema moderno che risolva tutti questi problemi attraverso l'utilizzo di tecnologie esistenti, tecniche di modellazione dei dati strutturati e un approccio che, mediante un processo di generalizzazione, aiuti a semplificare lo sviluppo del software stesso.

La Ricostruzione 3D di Bologna nel XVI Secolo

Il lavoro presentato ha come oggetto la ricostruzione tridimensionale della città di Bologna nella sua fase rinascimentale. Tale lavoro vuole fornire un modello 3D delle architetture e degli spazi urbani utilizzabile sia per scopi di ricerca nell’ambito della storia delle città sia per un uso didattico-divulgativo nel settore del turismo culturale. La base del lavoro è una fonte iconografica di grande importanza: l’affresco raffigurante Bologna risalente al 1575 e situato in Vaticano; questa è una veduta a volo d’uccello di grandi dimensioni dell’intero tessuto urbano bolognese all’interno della terza cerchia di mura. In esso sono rappresentate in maniera particolareggiata le architetture civili e ecclesiastiche, gli spazi ortivi e cortilivi interni agli isolati e alcune importanti strutture urbane presenti in città alla fine del Cinquecento, come l’area portuale e i canali interni alla città, oggi non più visibili. La ricostruzione tridimensionale è stata realizzata tramite Blender, software per la modellazione 3D opensource, attraverso le fasi di modellazione, texturing e creazione materiali (mediante campionamento delle principali cromie presenti nell’affresco), illuminazione e animazione. Una parte della modellazione è stata poi testata all’interno di un GIS per verificare l’utilizzo delle geometrie 3D come elementi collegabili ad altre fonti storiche relative allo sviluppo urbano e quindi sfruttabili per la ricerca storica. Grande attenzione infine è stata data all’uso dei modelli virtuali a scopo didattico-divulgativo e per il turismo culturale. La modellazione è stata utilizzata all’interno di un motore grafico 3D per costruire un ambiente virtuale interattivo nel quale un utente anche non esperto possa muoversi per esplorare gli spazi urbani della Bologna del Cinquecento. In ultimo è stato impostato lo sviluppo di un’applicazione per sistemi mobile (Iphone e Ipad) al fine di fornire uno strumento per la conoscenza della città storica in mobilità, attraverso la comparazione dello stato attuale con quello ricostruito virtualmente.

Thinkmix: dall'idea alla progettazione dello story network

Thinkmix è un network con componenti social che permette agli utenti di creare storie collaborando. La tesi illustra tutti gli step che hanno portato alla realizzazione di questo network: l'idea, la progettazione, lo sviluppo e la pubblicazione. Ritengo si tratti di un progetto ben riuscito e completo che mi ha permesso di esprimere totalmente le capacità acquisite durante il corso nelle varie materie (e non unicamente nella materia di riferimento) e di avvicinarmi a tematiche esterne a una laurea triennale (sicurezza informatica, marketing, acquisto e gestione di server dedicati, burocrazia per la pubblicazione di applicazione iOS e sito web con dominio).

Fog escaping: un'applicazione di mobile data CrowdSourcing per il supporto alla mobilità veicolare

In questa Tesi di laurea, si è affrontato il problema della mobilità veicolare in caso di nebbie. Si è quindi sviluppato un prototipo con architettura Client-Server, che si è soffermato maggiormente sull’analisi dei dati per la creazione di un percorso alternativo. Si è preso in considerazione il sistema operativo mobile di Apple, iOS7 che rappresenta uno dei Sistemi Operativi mobili maggiormente presenti sul mercato oggigiorno e che possiede un buon bacino di utenze. La parte Server è stata sviluppata secondo l’architettura REST; è presente un Server HTTP che riceve richieste e risponde in modo adeguato ai Client tramite lo scambio bidirezionale di dati in formato JSON. Nella parte Server è inclusa la base di dati: un componente molto importante poiché implementa al suo interno, parte della logica di Sistema tramite stored procedure. La parte Client è un’applicazione per dispositivi iPad e iPhone chiamata Fog Escaping; essa è stata sviluppata secondo il pattern MVC (Model- View-Controller). Fog Escaping implementa un algoritmo Greedy di ricerca del percorso alternativo, che può essere utilizzato per diverse tipologie di applicazioni.

THE EFFECTS OF WEB-BASED TECHNOLOGICAL RESOURCES IN A RURAL SCIENCE CLASSROOM

Today’s technology is evolving at an exponential rate. Everyday technology is finding more inroads into our education system. This study seeks to determine if having access to technology, including iPad tablets and a teacher's physical science webpage resources (videos, PowerPoint® presentations, and audio podcasts), assists ninth grade high school students in attaining greater comprehension and improved scientific literacy. Comprehension of the science concepts was measured by comparing current student pretest and post test scores on a teacher-written assessment. The current student post test scores were compared with prior classes’ (2010-2011 and 2009-2010) to determine if there was a difference in outcomes between the technology interventions and traditional instruction. Students entered responses to a technology survey that measured intervention usage and their perception of helpfulness of each intervention. The current year class’ mean composite scores, between the pretest and post test increased by 6.9 points (32.5%). Student composite scores also demonstrated that the interventions were successful in helping a majority of students (64.7%) attain the curriculum goals. The interventions were also successful in increasing student scientific literacy by meeting all of Bloom's cognitive levels that were assessed. When compared with prior 2010-2011 and 2009-2010 classes, the current class received a higher mean post test score indicating a positive effect of the use of technological interventions. The survey showed a majority of students utilized at least some of the technology interventions and perceived them as helpful, especially the videos and PowerPoint® presentations.

Integrated data acquisition and processing to determine metabolite contents, relaxation times, and macromolecule baseline in single examinations of individual subjects

Absolute quantitation of clinical (1)H-MR spectra is virtually always incomplete for single subjects because the separate determination of spectrum, baseline, and transverse and longitudinal relaxation times in single subjects is prohibitively long. Integrated Processing and Acquisition of Data (IPAD) based on a combined 2-dimensional experimental and fitting strategy is suggested to substantially improve the information content from a given measurement time. A series of localized saturation-recovery spectra was recorded and combined with 2-dimensional prior-knowledge fitting to simultaneously determine metabolite T(1) (from analysis of the saturation-recovery time course), metabolite T(2) (from lineshape analysis based on metabolite and water peak shapes), macromolecular baseline (based on T(1) differences and analysis of the saturation-recovery time course), and metabolite concentrations (using prior knowledge fitting and conventional procedures of absolute standardization). The procedure was tested on metabolite solutions and applied in 25 subjects (15-78 years old). Metabolite content was comparable to previously found values. Interindividual variation was larger than intraindividual variation in repeated spectra for metabolite content as well as for some relaxation times. Relaxation times were different for various metabolite groups. Parts of the interindividual variation could be explained by significant age dependence of relaxation times.

Quality Control for SP Performance Regarding Patient Portrayal in a High-Stakes OSCE

Introduction Since the quality of patient portrayal of standardized patients (SPs) during an Objective Structured Clinical Exam (OSCE) has a major impact on the reliability and validity of the exam, quality control should be initiated. Literature about quality control of SP’s performance focuses on feedback [1, 2] or completion of checklists [3, 4]. Since we did not find a published instrument meeting our needs for the assessment of patient portrayal, we developed such an instrument after being inspired by others [5] and used it in our high-stakes exam. Methods SP trainers from all five Swiss medical faculties collected and prioritized quality criteria for patient portrayal. Items were revised with the partners twice, based on experiences during OSCEs. The final instrument contains 14 criteria for acting (i.e. adequate verbal and non-verbal expression) and standardization (i.e. verbatim delivery of the first sentence). All partners used the instrument during a high-stakes OSCE. Both, SPs and trainers were introduced to the instrument. The tool was used in training (more than 100 observations) and during the exam (more than 250 observations). FAIR_OSCE The list of items to assess the quality of the simulation by SPs was primarily developed and used to provide formative feedback to the SPs in order to help them to improve their performance. It was therefore named “Feedbackstruckture for the Assessment of Interactive Role play in Objective Structured Clinical Exams (FAIR_OSCE). It was also used to assess the quality of patient portrayal during the exam. The results were calculated for each of the five faculties individually. Formative evaluation was given to the five faculties with individual feedback without revealing results of other faculties other than overall results. Results High quality of patient portrayal during the exam was documented. More than 90% of SP performances were rated to be completely correct or sufficient. An increase in quality of performance between training and exam was noted. In example the rate of completely correct reaction in medical tests increased from 88% to 95%. 95% completely correct reactions together with 4% sufficient reactions add up to 99% of the reactions meeting the requirements of the exam. SP educators using the instrument reported an augmentation of SPs performance induced by the use of the instrument. Disadvantages mentioned were high concentration needed to explicitly observe all criteria and cumbersome handling of the paper-based forms. Conclusion We were able to document a very high quality of SP performance in our exam. The data also indicate that our training is effective. We believe that the high concentration needed using the instrument is well invested, considering the observed augmentation of performance. The development of an iPad based application for the form is planned to address the cumbersome handling of the paper.

Una aplicación específica de las IDE: la información aeronáutica

El conjunto de actividades ligadas al transporte aéreo se ha convertido, a nivel global, en una importante fuente de recursos económicos, generación de empleo e incremento de la calidad de vida de los ciudadanos. Sin embargo, la situación crónica de saturación del espacio aéreo y de los propios aeropuertos limita enormemente el potencial crecimiento económico mundial basado en este sector estratégico del transporte. Como efecto colateral de esta saturación, se producen graves daños medioambientales debidos fundamentalmente, a la emisión directa a la atmósfera de mucha mayor cantidad de gases de efecto invernadero de la estrictamente necesaria. La solución al problema no es abordable exclusivamente a través de la construcción de nuevas infraestructuras aeroportuarias o la ampliación de las ya existentes. Los organismos mundiales relacionados con la aviación civil han diagnosticado que la forma anacrónica en la que actualmente se está gestionando la información aeronáutica (IA) impide que los proveedores de servicios de navegación aérea puedan tratar de forma eficiente y segura un mayor volumen de tránsito aéreo en el mismo espacio y lapso de tiempo. En definitiva, se advierte que la actual falta de eficiencia de la gestión de IA constriñe de forma notable el verdadero potencial del sistema aéreo mundial. Para solucionar este problema, se encuentra en marcha un ambicioso programa de trabajo que pretende mejorar la situación actual, dando respuesta a la necesidad de una interoperabilidad mundial desde un punto de vista análogo al que promueven las IDE en otros campos temáticos. Denominado genéricamente transición de AIS (Servicios de Información Aeronáutica) a AIM (Gestión de la Información Aeronáutica), este proceso está liderado por la Organización de Aviación Civil Internacional (OACI), encargada de su tutela y coordinación con los estados para evitar en lo posible evoluciones divergentes. Basada en la futura puesta en marcha de un modelo mundial de intercambio de datos aeronáuticos normalizados, el avance de esta iniciativa está obligando a los servicios AIS a replantearse la forma en la que, hasta el momento, publican y difunden el contenido de las denominadas Publicaciones de Información Aeronáutica (AIP). Todavía hoy (mediados de 2011), las AIS publican su cartografía en formato papel y estos mapas son de uso obligatorio en todos los vuelos de transporte de pasajeros que realicen las compañías aéreas. Aunque nada impide que los pilotos puedan llevar otra información adicional en instrumentos electrónicos propios (ordenadores portátiles, teléfonos, tabletas tipo iPad, y otros), el uso de los mapas en papel sigue siendo obligatorio. Esto arrastra algunas consecuencias relacionadas con su manejo (la cabina del piloto es muy pequeña), con la lectura de los mapas (hay cada vez más información en los mapas), con su actualización (hay que versionar constantemente los mapas para incorporar novedades con el gasto de impresión y distribución que supone) y con otros aspectos que pueden ser fácilmente mejorables por medio de las tecnologías emergentes, como por ejemplo el acceso ubicuo a la información espacial más actual. Entre los cambios que impulsará la iniciativa del cambio de AIS a AIM, está el que los mapas usados por los pilotos y otros técnicos de IA, dejarán de concebirse como productos terminales y cerrados para evolucionar hacia el conocido formato de datos distribuidos e interoperables que auspician las IDE, logrando con ello integrar la información, contenida en la definición de diferentes flujos de trabajo dentro del campo aeronáutico, de forma directa, transparente y eficiente.
