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.

A idéia de jogo em obras de John Cage e no ambiente da livre improvisação

Este texto examina as principais diferenças de enfoque relacionadas ao papel dos intérpretes na realização de duas diferentes propostas de jogo. Para tanto, são comparadas algumas obras de John Cage e as práticas de grupos que se dedicam à livre improvisação musical, principalmente do grupo Akronon.1 Procura-se demonstrar que as propostas de Cage, que estão situadas num plano conceitual, e as propostas da livre improvisação, que partem de uma prática experimental interativa baseada numa manipulação empírica dos sons, resultam em concepções bastante distintas a respeito do papel do intérprete. A partir desta perspectiva, afirma-se o caráter potente da livre improvisação que pode ser pensada enquanto prática de um jogo ideal conforme conceituação proposta pelo filósofo francês Gilles Deleuze

Creative process in globally distributed teams: a study of new product development in Volvo

With the business environments no longer confined to geographical borders, the new wave of digital technologies has given organizations an enormous opportunity to bring together their distributed workforce and develop the ability to work together despite being apart (Prasad & Akhilesh, 2002). resupposing creativity to be a social process, the way that this phenomenon occurs when the configuration of the team is substantially modified will be questioned. Very little is known about the impact of interpersonal relationships in the creativity (Kurtzberg & Amabile, 2001). In order to analyse the ways in which the creative process may be developed, we ought to be taken into consideration the fact that participants are dealing with a quite an atypical situation. Firstly, in these cases socialization takes place amongst individuals belonging to a geographically dispersed workplace, where interpersonal relationships are mediated by the computer, and where trust must be developed among persons who have never met one another. Participants not only have multiple addresses and locations, but above all different nationalities, and different cultures, attitudes, thoughts, and working patterns, and languages. Therefore, the central research question of this thesis is as follows: “How does the creative process unfold in globally distributed teams?” With a qualitative approach, we used the case study of the Business Unit of Volvo 3P, an arm of Volvo Group. Throughout this research, we interviewed seven teams engaged in the development of a new product in the chassis and cab areas, for the brands Volvo and Renault Trucks, teams that were geographically distributed in Brazil, Sweden, France and India. Our research suggests that corporate values, alongside with intrinsic motivation and task which lay down the necessary foundations for the development of the creative process in GDT.

Antropologia ed organizzazione delle imprese creative dell'ICT - Analisi della nascita, ascesa e suicidio organizzativo di un micro-distretto di aziende di comunicazione multimediale

Analisi "dall'interno" del settore della comunicazione multimediale, attraverso l'analisi di un caso aziendale complesso vissuto in prima persona dall'autrice. Il caso tratta di un micro-distretto di aziende della Grafica, del Web e del Multimedia nel suo ciclo di vita dal 1998 al 2003, analizzando le mutazioni del comportamento organizzativo nelle sue differenti fasi di nascita, ascesa e declino. L'obiettivo è quello di identificare i comportamenti organizzativi favorevoli e contrari alla sopravvivenza nel settore, fornendo indicazioni per un corretto comportamento manageriale in un ambito creativo relativo ad una rete di imprese co-specializzate.
