This paper analyzes how machine translation has changed the way translation is conceived and practiced in the information age. From a brief review of the early designs of machine translation programs, I discuss the changes implemented in the past decades in these systems to combine mechanical processing and the accessory work by the translator.

Corrigindo erros por meio de códigos lineares

Desde os trabalhos de Claude Shannon, em 1948, o avan¸co tecnológico na área das telecomunicações tem sido notável. Um grande problema na transmissão de mensagens por algum canal sempre residiu no fato de que, ao atravessar o canal, o conteúdo transmitido sofre distorções e chega modificado ao destinatário, o que impossibita a sua leitura correta. Graças ao trabalho de Shannon, esse problema obteve uma solução. Para identificar erros na transmissão de uma mensagem e corrigí-los, criaram-se os códigos corretores de erros, dos quais trataremos neste artigo, com destaque à classe dos códigos lineares. Para tanto, serão dados alguns resultados importantes relacionados aos corpos finitos, que são estruturas algébricas importantes sobre as quais se constroem esses códigos.

Sobre O tronco, romance de Bernardo Élis

The conception of O tronco was influenced by Hegel´s ideas. The genesis of this novel is in Bernardo Élis’ purpose of writing a monograph on land ownership conflicts in Goiás, later transformed into a new project, the novel O tronco. The same ideological position of the author gives the argumentative direction of the novel; his ideological background determines the choice of the theme, associated with images expanded by the procedures of argumentation that permeate the literary discourse. Thus, in face of the undeniable aesthetic value of Élis´work, we analyzed O tronco, specifically the argumentation that guides the literary narrative, enhanced by the artistic treatment of violence, its theme, as the result of the struggle for power. The novel was published in 1956; the author, heir to the literary regionalism of the 30s, through an artistic and calculated combination of the story of a local government and literature, accuses, judges the exacerbated domination of a particular social group in a region in Goiás.

Cárie oculta extensa: relato de caso clínico

The pattern of caries lesions has been modified over decades. If the presence or absence of a caries lesion is based upon only a visual examination, its diagnosis might become underestimated since dentinal lesions underneath non cavitated or minimally demineralized enamel is highly frequent in dental clinics. The aim of this paper is to report a clinical case of a child with an upper molar with questionable occlusal aspect, presenting asymptomatic pulpal hyperplasia on the distolingual pit. Periapical radiographic examination was essential for diagnosing hidden caries and elaborating the treatment plan. As part of the approach, removal of the decayed tissue and pulpotomy with calcium hydroxide were performed. The association of an accurate visual examination to an adequate oral radiographyis is extremely important in cases which the presence of hidden caries is doubtful. As a result, an early diagnosis and the reduction of more invasive interventions related to the oral health care of pediatric patients can be achieved as well.

Descrição do aparelho VABB (Vertically Activated Bite Block) para o tratamento da mordida aberta anterior

Nowadays, the correction of skeletal vertical dysplasia is considered a great challenge in Orthodontics. The skeletal open bite treatment presents limitations related to vertical growth pattern, the extension of open bite and especially the stability, which is very questioned. The treatment of skeletal open bite is mostly realized by the inhibition of vertical alveolar posterior development (relative intrusion) or absolute intrusion of posterior teeth, through vertical forces, generated by the action of masticatory muscles. The purpose of this article is to present a new appliance for the treatment of skeletal open bite, the VABB (Vertically Activated Bite Block) or modified Bite Block, whose action mechanism is to limit the vertical development of the molars, by the action of facial muscles and two bilateral expansion screws that provide a counterclockwise rotation of the mandible. It will also be presented a clinical case and the technical steps for the construction of this appliance.

Estimativa da altura por dimensões dentárias: uma revisão da literatura

The knowledge of Forensic Anthropology is very importance in cases of identification of human remains. One phase of this process is the study of human height, which can be accomplished with relative ease when intact corpses, complete skeletons or long bones are available. However, the experience of Forensic Dentistry is essential in situations in which there is only information of the skull or of the teeth. The objective of this study was to review in the literature and evaluate works concerning the estimate of the height calculated from dental dimensions. Carrea, in 1920, proposed the estimation of the probable height of an individual by developing formulas for maximum and minimum heights from measurements of the lower central and lateral incisors and canines. The method was used in the case "Josef Mengele", to complement estimates. Tested in the Brazilian population, 70% of match between the actual and the estimated stature were obtained. Using more precise instruments, in the modified method, 96% of correct matching were verified. Recently, a new formula was introduced to estimate height, from measurements of upper teeth, because the technique cannot be used when jaw is not available. The correlation between height and dental dimensions is demonstrated. However, there is still a lack in scientific literature in this field, and further studies are necessary. The estimate of height from dental dimensions can be very useful and important, especially in situations where the complete skeleton it not found, and long bones are not available.
