Entre o corpo e a escola: estudo sobre alguns dispositivos de colonização

We present some results of our studies on the relationship between educational processes and subjective processes. The object of our research is the body inserted in the school context in which we analyze tenderness as a field colonized by the dynamics of power. We have observed in the educational process both signs of capture as well as rupture facing the mechanisms of control coming from the market. We identified the implications of the body in the educational process in order to propose the aesthetic paradigm as a reference for educational action.

Camuflagem ortodôntica com dispositivos de ancoragem temporários ou cirurgia ortognática: parâmetros para a decisão

The polemical discussion between orthodontic therapeutic and surgical approaches with relation to borderline cases receives a new impulse with the emergence of temporary anchorage devices. This branch of Orthodontics has brought new treatment perspectives, but it has still been applied empirically, while the various factors involved in determining and conducting the treatment planning are neglected. The objective of the present study is to identify the several factors to be considered in both forms of treatment in order to provide the orthodontist with information that may contribute for the correct decision.

Power quality, smart meters and additional information from different power terms

This paper shows how the detailed examination of active and nonactive power components may produce new information for modern smart meters. For this purpose, a prototype of electronic power meter has been implemented and applied to the evaluation of the Conservative Power Theory (CPT). Considering five sorts of loads, under four different operating conditions, the experimental results indicate that the CPT is able to provide a good methodology for load characterization, which could possibly benefits consumers and power utilities in several different ways. The results also show that depending on the situation, the analysis of nonactive power terms may be more important than the observation of traditional power quality indices, such as total harmonic distortion, unbalance factors or the fundamental positive sequence power factor.

All sol-gel electrochromic smart windows: CeO2-TiO 2/Ormolyte/WO3

A solid state system having the configuration WO 3/Ormolyte/CeO2-TiO2 has been assembled. Syntheses routes for tungsten oxide WO3, and cerium-titanium CeO 2-TiO2 oxide sols, were developed. A novel solid electrolyte - Ormolyte is reported, which were obtained by the sol-gel process, they have a chemical stability due to the covalent bonds between the inorganic and organic phase, and were prepared with different [O]/[L] ratios, being the best for [O]/[L]=15. The variation of transmittance of the electrochromic device using the ormolyte [O]/[L]=15 was 35% (colored state) and 77% (bleached state).

Desenvolvimento e caracterização de dispositivos eletroluminescentes contendo uma blenda polimérica condutora e Zn2SiO4:Mn

Despite the great development of organic and polymeric electroluminescent materials, the large scale commercial application of devices made with these materials seems conditioned to specific cases, mainly due to the high cost and the low durability, in compared to conventional technologies. In this study was produced electroluminescent devices by a process simple, drop casting. Were produced electroluminescent films containing Zn2SiO4:Mn immersed in a conductive polymer blend with different thicknesses. The morphological characteristics of these films were studied by scanning electronic microscopy. These films were used in the manufacture of electroluminescent devices, in which the light emission properties of the developed material were evaluated. The blend was composed of the conductive polymer Poly(o-methoxyaniline), doped with p-toluene sulfonic acid, and an insulating polymer, Poly(vinylidene fluoride) and its copolymer Poly(vinylidene fluoride-cotrifluoroethylene). To this blend was added Zn2SiO4:Mn, thereby forming the composite. A first set of devices was obtained using composites with different weight fraction of polymeric and inorganic phases, which were deposited by drop casting over ITO substrates. Upper electrodes of aluminum were deposited by thermal evaporation. The resulting device architecture was a sandwich type structure ITO/ composite/ Al. A second set of devices was obtained as self-sustaining films using the best composite composition obtained for the device of the first set. ITO electrodes were deposited by RF-Sputtering, in both faces of these films. The AC electrical characterization of the devices was made with impedance spectroscopy measurements, and the DC electrical characterization was performed using a source/ meter unit Keithley 2410. The devices light emission was measured using a photodiode coupled to a digital electrometer, Keithley 6517A. The devices electrooptical characterization showed that the...

Dispositivos não convencionais para o rastreamento do corpo humano

Due to the popularity and need to learn sign language, there are tools that help in this type of communication. In Brazil, for example, the government offers professional Sign Language to assist communities, however, if think the hypothesis that people live in places difficult access, there is a difficult in movement of professionals to such places, besides bringing government overspending. Thus, a tool that simulates the movements of professional, fully exploiting the technological resources (cost-benefit) to enrich and provide a tool for communities, it becomes possible order to fill this gap. The system provides resources for editing movements, and these, later, are retrieved by tool for the visualization and representation of signals in a Virtual Environment. The resources used, provide two unconventional devices for tracking body, the Wiimote controllers and P5 glove.

Social TV: definição sobre a experiência do usuário

This article presents a study on the concept of social TV and the user’s experience. We made a literature review in search of the several meanings and features given to the subject. We have analyzed the aspects that express changes in the field, beginning with the TV set connected to the internet, which allows users to new experiences of socialization, previously available only in other devices. This new scenario provides a new platform called “TV everywhere”, the ubiquitous television that is everywhere, regardless of location, time or space. We have researched the origin of social TV and the process that altered the old television model. Finally, we propose a new term to express such changes regarding social television: “Social TV”, representing the user’s experience through the convergence between television and the Internet, shared locally and remotely through any technological means.
