A influência do conforto luminoso na satisfação dos profissionais que atuam no ginásio do Centro de Reabilitação Infantil, Natal-RN

This study addresses the environmental quality in therapeutic spaces for children's rehabilitation. The assumption that space is active and interfere in interpersonal relationships, highlights the importance of natural light to the hospital architecture, to foster the creation of environments that encourage and assist in the recovery of patients in the rehabilitation process. Therefore, interferes with health humanization through positive actions in the physiological and emotional effects of natural light, as facilitators of the health recovery process. In Brazil hospital openings systems projects are built exclusively to follow requirements of the local construction code which do not consider the landscape, but only ventilation and heat stroke; and the luminance levels are treated just as recommendations for artificial lighting. The National Policy for Healthcare Humanization presents the environmental comfort as a priority. However, it does not guidelines for achieving it. In this context this research aims to evaluate the lighting comfort in infant therapeutic areas from the professional satisfaction, in order to identify human preferences on the variables: technical and constructive aspects, relationship with the exterior, internal visual interface and quality elements. With this purpose it was adopted as research strategy the Post-Occupancy Evaluation (Technical Functional) through a multi method approach, which included a case study in the rehabilitation gym of Children Rehabilitation Center, at Natal, Rio Grande do Norte, and a reference study at SARAH Rehabilitation Center, Fortaleza Unit at Ceará, both in Brazil northeast. The results indicate that the definition of openings systems should consider external and internal factors to the building, as the natural landscape, the immediate surroundings and activities to be performed. The POE found out the preference of the professional visual privacy in detriment to other analyzed aspects. Thus, it is expected that this study can contribute to the discussion of luminous quality and generate inputs for future projects or renovations in the Children's Rehabilitation Centers, which should not be projected as hospitals

Visual IMML: um perfil UML para a modelagem de interfaces de usuário

The software development processes proposed by the most recent approaches in Software Engineering make use old models. UML was proposed as the standard language for modeling. The user interface is an important part of the software and has a fundamental importance to improve its usability. Unfortunately the standard UML does not offer appropriate resources to model user interfaces. Some proposals have already been proposed to solve this problem: some authors have been using models in the development of interfaces (Model Based Development) and some proposals to extend UML have been elaborated. But none of them considers the theoretical perspective presented by the semiotic engineering, that considers that, through the system, the designer should be able to communicate to the user what he can do, and how to use the system itself. This work presents Visual IMML, an UML Profile that emphasizes the aspects of the semiotic engineering. This Profile is based on IMML, that is a declarative textual language. The Visual IMML is a proposal that aims to improve the specification process by using a visual modeling (using diagrams) language. It proposes a new set of modeling elements (stereotypes) specifically designed to the specification and documentation of user interfaces, considering the aspects of communication, interaction and functionality in an integrated manner

Navegação cooperativa de um robô humanóide e um robô com rodas usando informação visual

This work presents a cooperative navigation systemof a humanoid robot and a wheeled robot using visual information, aiming to navigate the non-instrumented humanoid robot using information obtained from the instrumented wheeled robot. Despite the humanoid not having sensors to its navigation, it can be remotely controlled by infra-red signals. Thus, the wheeled robot can control the humanoid positioning itself behind him and, through visual information, find it and navigate it. The location of the wheeled robot is obtained merging information from odometers and from landmarks detection, using the Extended Kalman Filter. The marks are visually detected, and their features are extracted by image processing. Parameters obtained by image processing are directly used in the Extended Kalman Filter. Thus, while the wheeled robot locates and navigates the humanoid, it also simultaneously calculates its own location and maps the environment (SLAM). The navigation is done through heuristic algorithms based on errors between the actual and desired pose for each robot. The main contribution of this work was the implementation of a cooperative navigation system for two robots based on visual information, which can be extended to other robotic applications, as the ability to control robots without interfering on its hardware, or attaching communication devices

Um sistema inteligente de classificação de sinais de EEG para Interface Cérebro-Computador

The Brain-Computer Interfaces (BCI) have as main purpose to establish a communication path with the central nervous system (CNS) independently from the standard pathway (nervous, muscles), aiming to control a device. The main objective of the current research is to develop an off-line BCI that separates the different EEG patterns resulting from strictly mental tasks performed by an experimental subject, comparing the effectiveness of different signal-preprocessing approaches. We also tested different classification approaches: all versus all, one versus one and a hierarchic classification approach. No preprocessing techniques were found able to improve the system performance. Furthermore, the hierarchic approach proved to be capable to produce results above the expected by literature

Model-Driven requirements engineering process aided by ontologies and natural controlled languages

Researches in Requirements Engineering have been growing in the latest few years. Researchers are concerned with a set of open issues such as: communication between several user profiles involved in software engineering; scope definition; volatility and traceability issues. To cope with these issues a set of works are concentrated in (i) defining processes to collect client s specifications in order to solve scope issues; (ii) defining models to represent requirements to address communication and traceability issues; and (iii) working on mechanisms and processes to be applied to requirements modeling in order to facilitate requirements evolution and maintenance, addressing volatility and traceability issues. We propose an iterative Model-Driven process to solve these issues, based on a double layered CIM to communicate requirements related knowledge to a wider amount of stakeholders. We also present a tool to help requirements engineer through the RE process. Finally we present a case study to illustrate the process and tool s benefits and usage

Desenho de deficiência visual: uma experiência no ensino de artes visuais na perspectiva da educação inclusiva

Over the past 30 years, Art Education in interface with disabilities has been a subject of increasing interest in research in academia, especially with regard to Special Education, but still has some shortages in terms of socialization studies to discuss this type of teaching from the perspective of inclusive education. In this scenario, this paper presents an analysis from the field of teaching Visual Arts in the context of school inclusion, with emphasis on teaching drawing to the visually impaired. The conducted literature indicates a number of authors who discuss teaching drawing to people with visual disabilities, who are dedicated primarily to the Special Education context. In this sense, the shortage of research that discuss this teaching from the perspective of inclusive education, this research aimed at the inclusive approach to teaching drawing in the school context. Thus, the aim of this study was to develop a proposal for a pedagogical intervention in Visual Arts, with reference to drawing and its construction process, with the participation of seeing and unseeing students. Therefore, the methodological approach, which was qualitative, was the intervention research, in the light of the Bakhtinian principles of dialogism and otherness, with exploratory study characteristics. The locus of the research was the State School Admiral Newton Braga Faria, which is located in Alecrim, on the East Zone of Natal / RN and is near the Institute for Education and Rehabilitation of the Blind - IERC / RN. The class chosen for intervention was the 7th grade “C” afternoon shift, which had children aged 12 to 16, with 27 students enrolled, three students with disabilities: 02 blind girls and 01 deafblind boy with light hearing and visual loss. As interlocutors of the research, we could also count on the Art teacher who served as a collaborator, as well as teacher in the school’s Multifunction Resource Room. The instruments and research procedures were observation, semi-structured interview, field diary and the photo / video recording. In the development of research, we conducted 10 workshops with multisensory teaching sequences, articulating the physical, tactile and graphical expressions as intrinsic to the reading and production of drawing for both seeing and unseeing students. The process and data built on research allowed for a reflection on cultural experiences with drawing in the school context and on the interactions between seeing and unseeing students in the production and analysis of tactile-visual drawings. They also point out the construction of a teaching approach to drawing, in the context of the common class, from educational workshops that enable artistic and aesthetic interactions from the perspective of school inclusiveness. Thus, we argued that the mobilization of the tactile, physical and graphical expressions can be adopted in a multisensory approach that enables a pedagogical focus that involves all students and is not restricted to the presence of students with visual impairment.
