Uma abordagem comparativa da ironia: conceito, tropo e performance

We pursue in this paper an understanding of irony which is shared by both the German author Friedrich Schlegel and the critic Paul de Man. Irony is rather understood as a trope and as a performative act than as a concept, which has indeed consequences to the very legibility of texts.

Uma avaliação do conceito de regência e transitividade na tradição gramatical do português

In this paper, we study patterns of complementation as well as transitivity in Portuguese grammatical tradition aiming at verifying the motor of interest toward these subjects as well as eventual historic changes in the direction of the treatment they have been given. We analyze the concepts, the relations and the grounding notions in this camp, as well as the (in)transitive property of verbs in correlation with the status of their complements. Historically documented normative determinations of the notion of complementation and the modern reactions to such a view are relevant to our examination. Our conclusion moves toward a socio‑historic conditioning of traditional lessons, acknowledging, however, the natural existence of theoretical directions in the proposals.

Conceito amplo de sexualidade no processo de educação sexual

This paper discusses the concept of sexuality from a social and historical understanding. The broad concept of sexuality that goes beyond the genital is based on a vision that understands the body and the sexuality as representations that are constructed by social discourses. It also seeks to reflect on the process of sex education must be understood in its ethical-political dimension to assure everyone a space for formation of attitudes, not to work information on sexuality issues.

Aparelho Herbst x osteotomia sagital mandibular bilateral no tratamento do padrão II, classe II, divisão 1 em adultos: relato de casos

Two treatment options are available for adult patients with skeletal Class II malocclusion caused by mandibular deficiency: combined mandibular advancement surgery and orthodontic treatment or mandibular advancement appliance. This study aimed to analyze the effects of two therapeutic modalities of Class II malocclusion treatment with mandibular deficiency. Two distinct individuals with Class II malocclusion division 1 and mandibular deficiency were treated after growth spurt. The first individual used the Herbst appliance as a therapeutic option and the second individual was treated with bilateral sagittal osteotomy. The cephalometric, occlusion and face results were evaluated for both individuals. Correction of Class II malocclusion was observed on both Herbst and surgery patients resulting on a normal occlusal relationship with normal overjet and overbite. Therefore it was concluded that Herbst appliance can be used to treat borderline skeletal Class II in adult patients.

Avaliação anteroposterior da posição da mandíbula em crianças dolicofaciais com má oclusão Classe II, divisão 1 de Angle

In this study, it is proposed to evaluate the anteroposterior position of mandible in children with Angle Class II, division 1 malocclusions, to compare two different methods of evaluating the jaw position and verifying the correlation between these two methods. We selected 26 Brazilian children with vertical growth pattern and Angle Class II, division 1 malocclusions, aged between 7 years and 8 months to 9 years and 6 months. The evaluation of the anteroposterior position of the mandible was performed with the use of lateral cephalograms by cephalometric angular SNB and linear Pog-Nperp. Based on the results obtained, it was concluded that the SNB identified more children with mandibular retrusion than Pog-Nperp; the increased tip of the SN plane may have decreased values of SNB; Pog-Nperp minimizes the possibility of error in the anteroposterior position of the mandible, since it eliminates the variable tip of the anterior skull base (SN plane); none of the cephalometric measurements used are able to eliminate the influence of the nasion point in the anterior-posterior and vertical position; correlation between SNB and Pog-Nperp is very low.

Avaliação cefalométrica das alterações do perfil facial naturais e induzidas pelos aparelhos de Herbst e Bionator no tratamento da má oclusão de classe II, divisão 1ª

The aim of this study was to evaluate the facial profile changes due to natural growth and induced by Herbst appliance and Bionator in the treatment of Class II, division 1 malocclusion. In order to do that, we used a sample of 90 lateral radiographs of 45 individuals in pre-pubertal stage, divided up in two experimental groups and one control. The first group, composed of 15 brazilian individuals, with initial mean age of 9.4 years, was treated with the Herbst appliance for a period of seven months. The second experimental group consisting of 15 brazilian individuals, initial mean age of 9.9 years has gone through bionator therapy for an average period of 21 months. The control group of 15 individuals, who were not treated orthodontically, comes up from the Burlington Growth Centre, University of Toronto, Canada. The intragroup comparison was performed using the Student t test and intergroup comparisons by ANOVA complemented by the Bonferroni test. The results have shown that only the group treated with the Herbst appliance presented significant changes in facial profile with improvement of its convexity and lower lip protrusion.

Eficiência do aparelho Herbst bandado na correção da Classe II divisão 1 -relato de caso

The current reports the case of a young patient with malocclusion Class II division 1 on permanent dentition treated in two stages, rthopedics and orthodontics, respectively. At first, the banded Herbst appliance was used duringa 7 months period, followed by a T4K appliance, Trainer for Kids used as retention, and on the second stage the corrective Orthodontics was performed. The results showed the acquirement of a Class I dental relationship, which was kept stable, with excellent intercuspation, even after 5 years of the removal of the Herbst appliance, as well as the correction of the overjet and the reduction of the facial profile convexity. It can be concluded that the Herbst appliance was very efficient in correcting the Class II malocclusion, long term, also providing a very favorable effect on the facial profile.

Tratamento da classe II divisão 2 com aparelho de Herbst após o pico de crescimento puberal

Patients with Class II division 2 malocclusion and mandibular retrusion have limited treatment options after the growth peak, such as surgical-orthodontic treatment or mandibular advancement devices. Among bite-jumping devices, the Herbst appliance allows greater increase of mandibular growth since it does not require patient compliance and allows continuous use. This case report presents the treatment of a Class II division 2 malocclusion in a patient after growth peak, performed in two stages. The first stage included the upper incisors proclination and overjet increase with multibracket appliance to benefit next stage. The second stage involved mandibular advancement using Herbst appliance aiming to correct the Class II molar relationship. The treatment resulted in a stable occlusion with periodontal health, normal functions and facial aesthetics improvement. Dental and skeletal changes arising from treatment could be assessed by cephalometric analysis and superimposition of pretreatment and post-treatment cephalometric tracings. Antero-posterior discrepancy was corrected by means of dental movement as well as by mandibular growth increment stimulated by the Herbst appliance.

Estabilidade oclusal a longo prazo de Classe II, divisão 1, após tratamento com extração de pré-molares

Patients are looking for esthetic and functional changes when seeking orthodontic treatment and expect the remaining of a stable occlusion. Occlusion stability is one of the goals of the orthodontist; however, dental relationships changes in long-term can occur leading to a relapse of the treatment. Teeth and shape of arches tend to return to the original form, been the retention phase important after the appliance removal, even after several years of post-treatment. This article approaches a submission of a clinical case of Class II division 1 treated with extraction of premolars analyzing its long-term stability.

Tratamento da má-oclusão de classe II divisão 1 de Angle, com aparelho de Herbst splint metálico seguido de aparelho fixo, na dentição permanente

The Herbst appliance is currently one of the most used appliances for the correction of Class II division 1 with mandibular retrusion. When used in peak, or just after the peak of growth it can result in some skeletal gain, which is favorable to the correction of anteroposterior discrepancy with effective and stable results. This article aims to report a case of a patient with malocclusion Class II division 1 with mandibular retrusion, associated with maxillary protusion, treated in two stages: with Herbst splint metallic appliance followed by fixed appliance orthodontic treatment.

Tratamento da má oclusão de classe II, divisão 1, na dentadura mista com apareljo extrabucal removivel

Extraoral appliances represent an alternative for correction of Class II malocclusions. The application of external force leads to tooth movement and influence the growth of the maxillomandibular complex. This article aims to present the removable headgear as an adjuvant in the treatment of Class II division 1 in the mixed dentition.

Os limites e as possibilidades de uma sequência didática: o conceito de proporcionalidade e a aprendizagem de alunos do 5º ano do Ensino Fundamental

This study aimed to analyze the limits and possibilities of a didactic sequence, addressing the concept of proportionality in the learning of students in 5th year of elementary school. From the results of the Diagnostic Assessment Initial applied to students in a class of 5th grade of elementary school, we selected eight (8) students who participated in the constituent activities of that instructional sequence. For the development of this sequence were used theoretical elements of Genetic Epistemology (Piaget, 1990), the theory of fields of Conceptual Vergnaud (1996) and the definition of instructional sequence proposed by Zabala (1998). Finally, after 20 days of application of these activities, we applied the Diagnostic Assessment Final aimed at investigating which concepts related to proportionality were built by the participating students. By analyzing the collected data, it can be concluded the following about the possibilities of teaching sequence: 1) students who, in Diagnostica Home Assessment used the multiplication algorithm, but also did not indicate the comparison between quantities are now performing; 2) students who, in the Diagnostic Assessment Initial, used the addition algorithm, now gradually are using the multiplication algorithm; 3)students who, in the Diagnostic Assessment Initial, could not solve problems involving the idea of proportionality, are now resolving, however, still use, in large part, the addition operation as a strategy for this proportional thinking. Now, in relation to the limits of the sequence noted: 1)time sufficient to propose a higher number of problem conditions to be carried by students who may have been a trigger of construction have not through the proportional multiplication;2)the distant proposition situations of assimilation schemes (interpretation) of the students, which may have caused certain imbalance in them, preventing them from thinking about the problem situation;3)the rapid passage of...

Possibilidades de diálogo entre o conceito de ideologia em Bakhtin e a teoria das representações sociais

Introducing the theoretical trajectory of social representations theory, outline here the parallel between this theory in social psychology and the Bakhtinian concept of ideology. Both approaches include individual and society as inseparable and views the array of social construction of knowledge forms, related to day-to-day, or composed by formal record of science, as state, religion etc. With this interdisciplinary study, although limited, we hope to contribute to a better understanding of theories that have made important contributions to social psychology, linguistics, ethnography, cultural studies etc.

O conceito de região e problemas filosóficos: significado epistemológico da história regional e a constituição histórica do espaço liso e do espaço estriado

The concept of region raises two related historical problems. First of all, it concerns the epistemological accomplishment of regional history, since the need to provide a total history, one of the main challenges of the Annales movement, undergoes an impact with the notion of local, so that the overflight of the historic totality becomes nowadays an intensive totality. The historian who overflies the reality is replaced by the wanderer historian. In addition to this epistemological question, we can think about the historical feature of spaces. From an ontological point of view, according to the modes of its composition, as well as from the standpoint of its practical constitution, space can be either smooth or striated. These types of space belong to the Gilles Deleuze s nomadology and their definition might improve the characterization and description of historical spaces with regard to a certain contemporary historiographical movement known as the New Cultural History.Key Words: history;space;nomadism.
