The relation between patient and physician in most modern Health Care Systems is sparse, limited in time and very inflexible. On the other hand, and in contradiction with several recent studies, most physicians do not rely their patient diagnostics evaluations on intertwined psychological and social nature factors. Facing these problems and trying to improve the patient/physician relation we present a mobile health care solution to improve the interaction between the physician and his patients. The solution serves not only as a privileged mean of communication between physicians and patients but also as an evolutionary intelligent platform delivering a mobile rule based system.

Over the last decade component-based software development arose as a promising paradigm to deal with the ever increasing complexity in software design, evolution and reuse. SHACC is a prototyping tool for component-based systems in which components are modelled coinductively as generalized Mealy machines. The prototype is built as a HASKELL library endowed with a graphical user interface developed in Swing

Program slicing is a well known family of techniques used to identify code fragments which depend on or are depended upon specific program entities. They are particularly useful in the areas of reverse engineering, program understanding, testing and software maintenance. Most slicing methods, usually targeting either the imperative or the object oriented paradigms, are based on some sort of graph structure representing program dependencies. Slicing techniques amount, therefore, to (sophisticated) graph transversal algorithms. This paper proposes a completely different approach to the slicing problem for functional programs. Instead of extracting program information to build an underlying dependencies’ structure, we resort to standard program calculation strategies, based on the so-called Bird- Meertens formalism. The slicing criterion is specified either as a projection or a hiding function which, once composed with the original program, leads to the identification of the intended slice. Going through a number of examples, the paper suggests this approach may be an interesting, even if not completely general alternative to slicing functional programs

A common problem among information systems is the storage and maintenance of permanent information identified by a key. Such systems are typically known as data base engines or simply as data bases. Today the systems information market is full of solutions that provide mass storage capacities implemented in different operating system and with great amounts of extra functionalities. In this paper we will focus on the formal high level specification of data base systems in the Haskell language. We begin by introducing a high level view of a data base system with a specification of the most common operations in a functional point of view. We then augment this specification by lifting to the state monad which is then modified once again to permit input/output operations between the computations

Chronic stress impairs cognitive function, namely on tasks that rely on the integrity of cortico-limbic networks. To unravel the functional impact of progressive stress in cortico-limbic networks we measured neural activity and spectral coherences between the ventral hippocampus (vHIP) and the medial prefrontal cortex (mPFC) in rats subjected to short term stress (STS) and chronic unpredictable stress (CUS). CUS exposure consistently disrupted the spectral coherence between both areas for a wide range of frequencies, whereas STS exposure failed to trigger such effect. The chronic stress-induced coherence decrease correlated inversely with the vHIP power spectrum, but not with the mPFC power spectrum, which supports the view that hippocampal dysfunction is the primary event after stress exposure. Importantly, we additionally show that the variations in vHIP-to-mPFC coherence and power spectrum in the vHIP correlated with stress-induced behavioral deficits in a spatial reference memory task. Altogether, these findings result in an innovative readout to measure, and follow, the functional events that underlie the stress-induced reference memory impairments.

A unique neural electrode design is proposed with 3 mm long shafts made from an aluminum-based substrate. The electrode is composed by 100 individualized shafts in a 10 × 10 matrix, in which each aluminum shafts are precisely machined via dicing-saw cutting programs. The result is a bulk structure of aluminum with 65 ° angle sharp tips. Each electrode tip is covered by an iridium oxide thin film layer (ionic transducer) via pulsed sputtering, that provides a stable and a reversible behavior for recording/stimulation purposes, a 40 mC/cm2 charge capacity and a 145 Ω impedance in a wide frequency range of interest (10 Hz-100 kHz). Because of the non-biocompatibility issue that characterizes aluminum, an anodization process is performed that forms an aluminum oxide layer around the aluminum substrate. The result is a passivation layer fully biocompatible that furthermore, enhances the mechanical properties by increasing the robustness of the electrode. For a successful electrode insertion, a 1.1 N load is required. The resultant electrode is a feasible alternative to silicon-based electrode solutions, avoiding the complexity of its fabrication methods and limitations, and increasing the electrode performance.

The lack of a commonly accepted de nition of a software component, the proliferation of competing `standards' and component frameworks, is here to stay, raising the fundamental question in component-based development of how to cope in practice with heterogeneity. This paper reports on the design of a Component Repository aimed to give at least a partial answer to the above question. The repository was fully speci ed in Vdm and a working prototype is currently being used in an industrial environment

With the number of elderly people increasing tremendously worldwide, comes the need for effective methods to maintain or improve older adults' cognitive performance. Using continuous neurofeedback, through the use of EEG techniques, people can learn how to train and alter their brain electrical activity. A software platform that puts together the proposed rehabilitation methodology has been developed: a digital game protocol that supports neurofeedback training of alpha and theta rhythms, by reading the EEG activity and presenting it back to the subject, interleaved with neurocognitive tasks such as n-Back and Corsi Block-Tapping. This tool will be used as a potential rehabilitative platform for age-related memory impairments.

Este livro tem como objectivo exemplificar a realização do chamado relatório psiquiátrico-forense, nomeadamente em seu aspecto criminal. O livro é constituído por dois planos que são complementares. No primeiro plano de uma forma ficcional, a partir dos elementos existentes nos autos, expressamos o drama e a trama das histórias vividas e criadas pelos homens. O segundo plano é alavancado a partir da análise técnica psiquiátrico-forense tendo como parâmetros os ditames bio-psicológicos que delineiam o Código Penal Português. A obra também resguarda o papel e a importância da psiquiatria forense em sua faina diária que é de auxiliar os juízes nas complexas questões da responsabilidade penal. Esperamos assim contribuir para que psiquiatras, psicólogos e juristas tenham em mãos mais um instrumento que possa ajudá-los na tarefa de arrostar, de tempos em tempos, uma sociedade em eterna transformação.

Pectus excavatum is the most common deformity of the thorax. A minimally invasive surgical correction is commonly carried out to remodel the anterior chest wall by using an intrathoracic convex prosthesis in the substernal position. The process of prosthesis modeling and bending still remains an area of improvement. The authors developed a new system, i3DExcavatum, which can automatically model and bend the bar preoperatively based on a thoracic CT scan. This article presents a comparison between automatic and manual bending. The i3DExcavatum was used to personalize prostheses for 41 patients who underwent pectus excavatum surgical correction between 2007 and 2012. Regarding the anatomical variations, the soft-tissue thicknesses external to the ribs show that both symmetric and asymmetric patients always have asymmetric variations, by comparing the patients’ sides. It highlighted that the prosthesis bar should be modeled according to each patient’s rib positions and dimensions. The average differences between the skin and costal line curvature lengths were 84 ± 4 mm and 96 ± 11 mm, for male and female patients, respectively. On the other hand, the i3DExcavatum ensured a smooth curvature of the surgical prosthesis and was capable of predicting and simulating a virtual shape and size of the bar for asymmetric and symmetric patients. In conclusion, the i3DExcavatum allows preoperative personalization according to the thoracic morphology of each patient. It reduces surgery time and minimizes the margin error introduced by the manually bent bar, which only uses a template that copies the chest wall curvature.

Pectus carinatum (PC) is a chest deformity caused by a disproportionate growth of the costal cartilages compared to the bony thoracic skeleton, pulling the sternum towards, which leads to its protrusion. There has been a growing interest on using the ‘reversed Nuss’ technique as minimally invasive procedure for PC surgical correction. A corrective bar is introduced between the skin and the thoracic cage and positioned on top of the sternum highest protrusion area for continuous pressure. Then, it is fixed to the ribs and kept implanted for about 2–3 years. The purpose of this work was to (a) assess the stresses distribution on the thoracic cage that arise from the procedure, and (b) investigate the impact of different positioning of the corrective bar along the sternum. The higher stresses were generated on the 4th, 5th and 6th ribs backend, supporting the hypothesis of pectus deformities correction-induced scoliosis. The different bar positioning originated different stresses on the ribs’ backend. The bar position that led to lower stresses generated on the ribs backend was the one that also led to the smallest sternum displacement. However, this may be preferred, as the risk of induced scoliosis is lowered.

The objectives of this empirical study are, on the one hand, to evaluate the level of disclosure, about liquidity risk, practiced by fourteen banking institutions that operate in Portuguese financial system, and, on the other hand, to assess the determinants of that disclosure. To this end, we have used content analysis, as data collection technique, and have examined the information disclosed in the annual reports of the fourteen banks, for the period between 2007 and 2011. For this purpose we have constructed a disclosure index, based on the recommendations of the Basel Committee on Banking Supervision, and have defined a set of potentially explanatory variables related to the level of disclosure. The results demonstrated that size and financial year were the variables that showed up as statistically significant in explaining the level of disclosure.

This paper investigates realism in character computer animation, which triggered the development of new techniques and aesthetic in spectacular cinema and contemporary culture. With the advent of motion or performing capture, animation has made possible that virtual characters or digital creatures reach higher levels in emotional acting, taking place in virtual cinematic worlds or even special effects movies. This technology, when placed at the service of imagination and fantasy can provide new dimensions in character motion and communication. In this context, projects like Peter Jackson’s (2001) The Lord of the Rings, James Cameron’s Avatar (2009) and more recently Steven Spielberg’s Tintin (2011) demonstrate that motion technology is constantly evolving, and it represents a credible option to explore new techniques and aesthetic in contemporary animation.

En la educación especial para autistas el método principal de la comunicación se hace con imágenes que hacen posible la comunicación entre profesores y alumnos. El gran problema de un niño autista es la enfermedad que afecta la comunicación del niño. A partir del analisis del sistema de comunicación vigente - Las cifras del Sistema de Comunicación (PEC) – se detectaron algunas inconsistencias en los símbolos utilizados, como son la falta de informidad y usabilidad visual. Así, este trabajo parte de la propuesta de cambiar, renovando el sistema. Nos proponemos a la creación de un conjunto de símbolos uniforme, coherente y convincente. Una vez que, desde el punto de vista del diseño y la ilustración, consideramos como esencial para la enseñanza del autista un establecimiento de determinada calidad en las imágenes e ilustraciones utilizadas en este universo. La investigación se centrará en el campo de la ilustración y el producto se sentará en el intento de reformular el sistema de comunicaciones implementada hoy en día, con el objetivo principal de hacer la comunicación fácil e inmediata entre los niños autistas, los profesores, padres y amigos. Es decir, buscamos la eficacia de comunicación entre el autista y los que los rodean.

O papel criativo dos autores na conceção de conteúdos para publicações eletrónicas de álbuns ilustrados tem sido preterido pelo papel de programador, já que na tentativa de explorar o mercado editorial online as editoras tendem a recriar o seu portefólio impresso no mundo das publicações virtuais[1] . Esta preferência tem como consequência a criação de conteúdos que ignoram as diferenças da manipulação e experiência de leitura que os diferentes tipos de publicação permitem. Devem os álbuns ilustrados eletrónicos libertar-se das ligações ao códice tradicional, permitindo que se legitimem enquanto objetos autónomos, assumindo as suas próprias regras de leitura? Qual o papel do ilustrador neste processo?

Tendo como ponto de partida um caso de estudo que compara dois livros de actividades (um livro tradicional no suporte físico, “Wreck this Journal”, adaptado para um livro digital, “Wreck this App”) da autora Keri Smith, propomo-nos analisar fundamentalmente as possibilidades do desenho de representação em ambos os suportes. Abordaremos ainda outros temas paralelos segundo parâmetros previamente definidos, que irão permitir comparar e analisar as propriedades de cada objecto, enquanto potencial espaço de representação. Este trabalho procura, assim, demonstrar de que forma estes dois suportes se complementam, livro impresso e livro digital, e de que forma podemos beneficiar com a introdução de novas técnicas e da possível transferência de conhecimentos adquiridos num objecto de estudo para o outro. Independentemente de permitirem diferentes experiências de interacção e de registo, torna-se relevante a forma com que estimulam a criatividade e a procura de novas formas de representação.

From silence to action: silence taken as a foundational action that allows creative processes. It is a blankness that precedes the moment of creation but also stands for a search for perfection, the un-representable, the Sublime. The ‘art moment’ is that what is created from such emptiness, in the vertiginous abyss from nowhere to action. We will work this complex process of understanding if an action precedes the silence or if the silence precedes the action. Analyzing art process, considering its phases, from the tension between either to create or not to create will be related with the potency refereed by Agamben regarding Bartleby: starting with blankness, with the invisibility of potency, when communication is urgent. When “the blues” are called into participation, when the melancholic state installs the potency of the work both to grow or be doubted, of to do or not to do, how do we read agency? Is silence the action? Should the action rest in silence? What to do? Remain in the state of pure potency or prove the impossibility to create form? Nowadays, the pensive image counters the logic of the narrative action. On the one hand, the image extends the action on the other hand suspends any given presumption. The artistic process carries on, in its poetic freedom, a search without the enslavement of representational forms.

The evolution of computer animation represents one of the most relevant andrevolutionary aspects in the rise of contemporary digital visual culture (Darlew,2000), in particular, phenomena such as cinema “spectacular “ (Ibidem) and videogames. This article analyzes the characteristics of this “culture of simulation” (Turkle, 1995:20) relating the multidisciplinary and spectrum of technical and stylistic choices to the dimension of virtual characters acting. The result of these hybrid mixtures and computerized human motion capture techniques - called virtual cinema, universal capture, motion capture, etc. - cosists mainly on the sophistication of “rotoscoping”, as a new interpretation and appropriation of the captured image. This human motion capture technology, used largely by cinema and digital games, is one of the reasons why the authenticity of the animation is sometimes questioned. It is in the fi eld of 3D computer animation visual that this change is more signifi cant, appearing regularly innovative techniques of image manipulation and “hyper-cinema” (Lamarre, 2006: 31) character’s control with deeper sense of emotions. This shift in the culture that Manovich (2006: 27) calls “photo-GRAPHICS” - and Mulvey (2007) argue that creates a new form of possessive relationship with the viewer, in that it can analyze in detail the image, it can acquire it and modify it - is one of the most important aspects in the rise of Cubbit’s (2007) “cinema of attraction”. This article delves intrinsically into the analyze of virtual character animation — particularly in the fi eld of 3D computer animation and human digital acting.
