3D semantic models for dental education

This paper explores the benefits of using immersive and interactive virtual reality environments to teach Dentistry. We present a tool for educators to manipulate and edit virtual models. One of the main contributions is that multimedia information can be semantically associated with parts of the model, through an ontology, enriching the experience; for example, videos can be linked to each tooth demonstrating how to extract them. The use of semantic information gives a greater flexibility to the models, since filters can be applied to create temporary models that show subsets of the original data in a human friendly way. We also explain how the software was written to run in arbitrary multi-projection environments. © 2011 Springer-Verlag.

A multiple intelligences theory-based 3D virtual lab environment for digital systems teaching.

This paper describes a 3D virtual lab environment that was developed using OpenSim software integrated into Moodle. Virtuald software tool was used to provide pedagogical support to the lab by enabling to create online texts and delivering them to the students. The courses taught in this virtual lab are methodologically in conformity to theory of multiple intelligences. Some results are presented.

Design and evaluation of an advanced virtual reality system for visualization of dentistry structures

This paper presents the development of an application created to assist the teaching of dental structures, generate rich content information and different manners of interaction. An ontology was created to provide semantics informations for virtual models. We also used two devices gesture-based interaction: Kinect and Wii Remote. It was developed a system which use intuitive interaction, and it is able to generate three dimensional images, making the experience of teaching / learning motivating. The projection environment used by the system was called Mini CAVE. © 2012 IEEE.

Geometric modeling from the medical images in the CAD system to support prosthesis design

This paper presents an individual designing prosthesis for surgical use and proposes a methodology for such design through mathematical extrapolation of data from digital images obtained via tomography of individual patient's bones. Individually tailored prosthesis designed to fit particular patient requirements as accurately as possible should result in more successful reconstruction, enable better planning before surgery and consequently fewer complications during surgery. Fast and accurate design and manufacture of personalized prosthesis for surgical use in bone replacement or reconstruction is potentially feasible through the application and integration of several different existing technologies, which are each at different stages of maturity. Initial case study experiments have been undertaken to validate the research concepts by making dimensional comparisons between a bone and a virtual model produced using the proposed methodology and a future research directions are discussed.

O fazer docente no processo de mudança das teorias pedagógicas

Este artigo constitui uma revisão bibliográfica sobre as diferentes teorias pedagógicas e sua relação com o fazer docente. Apresenta o contraponto entre a escola tradicional, fundamentada na força dos modelos e no estudo dos clássicos da história humana, e a escola nova, que defende a ideia de centralidade na atividade do aluno e em métodos e programas baseados na experiência da criança. Adota, para tanto, o seguinte referencial teórico: Saviani (2008a/2008b), Snyders (1974), Gramsci (1991), Luzuriaga (1961), Bloch (1951), Hernandez (1998), Ball (1994) e Gauthier (1998), entre outros. Propõe uma reflexão sobre a escola como principal recurso estratégico de educação das comunidades humanas e sobre os saberes necessários à profissionalização do ensino. Debate, ainda, as pedagogias adotadas pela Secretaria de Estado da Educação de São Paulo, nas últimas décadas, incluindo o novo currículo oficial, e a influência do Estado e do mercado na prática docente.

A utilização da tecnologia nas artes, design e engenharia, como ferramenta de vanguarda e sustentabilidade

Art can be understood as a process in which knowledge is used to perform certain skills. From Latin ARS, technical means and / or ability, in Greece, there was the word art, but "Tekne", which originated from the word "technical." So art and technique are present in sculptures, paintings, shoes or ships. In this sense, designers, engineers and all professionals who use technology can be called artists. Considerations must be made regarding the level of energy embedded in the material from its production until its use, even considering recycling, sustainability and life cycle of materials. This study aimed to present the use of scanning technology and 3D virtual modeling and its application in prototyping with CNC (Computed Numerical Control) as a tool in current use cutting-edge courses in arts, design and engineering and their relations with sustainability.

Análiseda percolação de água em barragem de terra pelo método da eletrorresistividade

Interventions in nature made by man are very common since the beginnings of human history, especially in the case regarding the storage of water. The construction of dams have been and still are fundamental in maintaining human life due to the vital importance that water plays. The size of these structures vary according to need, such as water catchment, fish-farming or electricity generation. Embankment dams are the most common type of these structures. Can be defined as dams natural material obtained from loan chambers located near the dam site. This type of barrier may be divided into earth dams and rockfill dams. The study area covers an earth dam located in Cordeirópolis (SP) and is essentially composed of diabases altered soil of the Serra Geral Formation of the Paraná Basin. With the aid of geophysics, more specifically of the Electrical Resistivity method, the aim is to check any water infiltration zones in the dam's body. Given the risks associated with water seepage in earth dams, that may generate breakdown structures, erosion, and consequently accidents and / or harmful factors in the nearby areas. One of the main structural problems married by water infiltration is the possible generation of pipes that could jeopardize the dam structure. This work aims to contribute towards the evaluation of the effectiveness of using an indirect technique of research and monitoring in aid to direct research techniques such as piezometers and drive stakes. The results are presented in the form of 2D and 3D geophysical models, the analysis shows a low resistivity zone with typical values of the presence of humidity originating upstream of the dam and downstream bottleneck trend, that are the basis for interpretation by percolation or not water in the dam

Desenvolvimento de aplicações Web com base em modelagem 3D: módulo Android

This project brings the development of an Android application which will allow users to access 3D models on web. The application developed allows Android devices to access web pages which have code that should use OPENGL to renderize. To demonstrate this functionality, an example web application was build, using technologies such as X3DOM and HTML5, which uses WebGL to get renderized. This web application gives to the user an environment of a virtual city, where he could surf by and interact with the objects. The Android application brings this immersion to the mobile world, also. The access and storage of data was developed a Webserver, which bring to the web application a simple API to give access to the database
