Direito autoral e tecnologias de informação e comunicação no contexto da produção, uso e disseminação de informação: um olhar para as Licenças Creative Commons

The development of information and communication technologies, in particular, Internet, and its Web 2.0 information environment has led to significant changes in contemporary society as to the ways of producing informational content. Collaboration and remix, favored by the new services and applications resulting from the development of the Web, are practices which contribute for the exponential growth of information producers. An important part of humanity ceases to be a mere consumer of symbolic goods and becomes a member in a society that sees in the collaboration and remix a new form of creation, use and dissemination of intellectual content. However, as such practices involve the production and use of information intelectual content, and are ruled by a legisltion which determine determines under what conditions the author and the user must produce and use the intellectual work. This legislation established for a context prior to the develompment of the Web has created an imbalance in the context of Web 2.0 which needs to be solved in some way so as to provide the required rebalance for the flow of information. This study explores the collaborative Web environment, the scope of copyright law in Web enviroment and the Creative Commons licenses as an alternative for producers and users of information to create, recreate, share, use, reuse and disseminate legally the intellectual production for the benefit of the construction of knowledge.

Trilled sounds in Brazilian Portuguese: Phonetic and phonological characterization

This paper deals with the phonological definition of trills in Brazilian Portuguese. The phonemic existence of two distinctive R's, one soft the other strong, is taken for granted. After reviewing the ideas of some Portuguese-speaking phoneticians on this matter, 146 occurrences of R's - recorded by two informants - were acoustically analyzed, the formants' general aspect and the length of the R segments were studied in the resulting spectrograms. The phonological table displayed in the conclusion does not include any trill. The soft phoneme /r/, instead, is classified as an interrupted apico-alveolar tap with a retroflex allophone. Naturalization between these two units is discarded.t

Mandible protrusion and decrease of TMJ sounds: An electrovibratographic examination

This study quantified by, electrovibratography, the amount of mandible protrusion required to decrease significantly temporomandibular joint (TMJ) vibratory energy as an aid in the diagnosis of the recapture of anteriorly displaced disk. Eighteen patients diagnosed as having anterior disk displacement with reduction and TMJ clicking were submitted to electrovibratographic examination at the first appointment and treated with a stabilizing appliance and anterior positioning appliance with 1 to 5 mm protrusion. Vibratory energy was checked in each of these positions. Baseline data were used as control. At the first appointment, the patients had vibrations with more elevated intensities at the middle and late phases of the mouth opening cycle. At only one clinical step, mandible protrusion was obtained with the anterior repositioning appliance, ranging from 1 to 5 mm protusion. At each new position, a new electrovibratographic exam was made. After the 5-mm mandibular projection, only 2 patients presented vibration, with means between 0.6 and 2.8 Hz. Data were analyzed statistically by ANOVA and Tukey's test (α=0.05). The outcomes of this study indicate that 3 mm is the minimum amount of mandible protrusion to significantly decrease the TMJ vibratory energy and to recapture the displaced articular disk.

Effect of occlusion on joint sounds in asymptomatic individuals.

Occlusion is a predisposing factor for Temporomandibular Dysfunctions (TMD) of the joint, whose first sign and/or symptom is usually joint sound. To verify the effect of occlusion on joint sounds, temporomandibular joints (TMJ) were analyzed in 78 asymptomatic individuals with various dental conditions. Electrosonography was used to determine the intensity of the vibration in the temporomandibular joint (TMJ) on opening and closing the mouth. Transducers (piezoelectric accelerometer) were placed on the right and left joints. Results were tabled and analyzed using the Kruskal-Wallis test (a=0.05). It was concluded that TMJ vibration in partly edentulous individuals from Kennedy classes I, II and III is statistically higher than in dentate and fully edentulous subjects.

Joint sounds in complete denture wearers. Literature review.

Long-term denture wearers can present with prosthesis instability, reduced occlusal vertical dimension and incorrect positioning of the jaw. This can lead to muscular changes and joint vibration. This study presents the main considerations related to joint vibrations in partially or totally edentulous patients. Occlusal treatment improves the disc-condyle relationship in the mandibular fossa. Furthermore, a detailed clinical exam and anamnesis must be performed to identify the dysfunction and its etiology, so that appropriate treatment can be provided.

Creative commons: A convergence model between the ideal of commons and the possibilities of creation in contemporary times, opposed to copyright impediments

The contemporary individual finds on the Internet and especially on the Web facilitating conditions to build a basic infrastructure based on the concept of commons. He also finds favorable conditions which allow him to collaborate and share resources for the creation, use, reuse, access and dissemination of information. However, he also faces obstacles such as Copyright (Law 9610/98 in Brazil). An alternative is Creative Commons which not only allows the elaboration, use and dissemination of information under legal conditions but also function as a facilitator for the development of informational commons. This paper deals with this scenario.

O desafio de desenvolver artistas criativos no mundo das mídias digitais

From the second half of the twentieth century, with the proposal of working active listening, exploring sounds, the experience, the search for new forms of contemporary music notation, improvisation and experimental music composition, arise music educators Paynter Schafer and Koellreutter, known by the active method of second generation who contributed greatly to the development of creative processes in the classroom. Also arises, in the same period, the encounter between art and technology, expanding opportunities through digital media, open, participatory and interactive works such as Video art, Web art, Nanoarte and Locative Art, augmented, not only against the art with the public, through connections mediated by digital interfaces, providing new learning situations attractive for the development of creativity and artistic production as challenges in contemporary.
