Studies about efficiency have gained dimension, in Brazil, since the early 90’s. Same decade that the Civil Aviation System suffers important changes in terms of regulations. Such transformations have echoed effects currently, with some significant trend for international standards. This paper focuses on one of the agents from the Brazilian Civil Aviation System, the airlines companies, which aimed on analyze and evaluate both passengers and cargo air transport, by using data envelopment analysis (DEA), during the period of 2005 to 2010. The yearbooks of ANAC, corresponding at the period from 2005 to 2010, were used as data base in this present study. The technique was applied to 14 companies, which through Stepwise process of variables validation was possible to compose a compact, but complete model, that could translate the reality of companies. This model was composed by one output, Total Income, and by four inputs, Total Costs, Total Domestic Passenger, Total Cargo and Total International Passengers. However, this approach has some flaws. Therefore in order to remedy it, it was required to apply the method Frontier Inverted, one of the alternatives proposed in the literature, which ensured an improvement in the context of efficiencies due to biggest discrimination of airlines. As a result of the DEA-BCC process, oriented by output, TAM 2005 was considered the most efficient company, however GOL and Webjet companies concentrated in 2007 their worst levels

O objetivo do presente estudo foi identificar as representações sociais de professores sobre indisciplina em sala de aula. Adotamos a teoria das Representações Sociais como referencial teórico. Os dados foram coletados por meio de entrevistas individuais semiestruturadas. Os participantes foram três professores do ensino técnico, três do ensino médio e três de ambos os ensinos, totalizando nove docentes de uma Escola Técnica Estadual (ETEC) do interior paulista, pertencente ao Centro Estadual de Educação Tecnológica Paula Souza. Utilizando a análise de conteúdo, definimos três eixos temáticos: causas atribuídas à indisciplina, alternativas para lidar com a questão e concepção de indisciplina, para os quais caracterizamos categorias, em que obtivemos a frequência de respostas. Na análise dos resultados, podemos indicar que a representação social da indisciplina parece estar objetivada, principalmente, nas questões individuais dos alunos. Os professores relataram diferentes causas da indisciplina para os ensinos médio e técnico. Foram indicadas algumas diferenças na maneira de lidar com o aluno adolescente e adulto e entre as causas e as alternativas para lidar com a indisciplina. As representações sociais dos professores sobre a indisciplina ancoraram-se, em sua maioria, num referencial tradicional, associado à responsabilização do aluno e da família.

The Jararaca River Basin suffers significative environmental impacts caused by inaccurate land use. In Brazil, the areas for permanent preservation are defined and protected by the 2012 Federal Law 12.651. These areas are located in the bank side and other specific places. The objective of this paper was to analyze the results of possible alternatives in function of different procedures used in the proposal elaboration. The methodology used was the elaboration of a priority map for the recovery of these areas using the Geographic Information System with multicriterial analyses and comparing it with the guidelines from the Jararaca River Basin Management Plan. As a result, there were identified differences in the priorities defined by technical issues from the priorities defined by public consultation process.

Complete denture fabrication can be a treatment challenge for many dentists, especially when the patient has remaining teeth. So, planning for use of clinical alternatives to improve the treatment prognosis and to enable greater comfort to patient must be considered. This case report describes the use of remaining roots to aid in the stability, support and retention of root-supported overdentures. Thus, immediate prostheses were planned for temporary rehabilitation prior to definitive overdentures. The aim of this study was to demonstrate the planning of root-supported overdentures attached with a ball system for retention associated with immediate dentures between the periods of preparation to fabrication of the definitive overdentures. The proposed treatment met the patient's needs such as being able to carry on normal activities during the sequencing of procedures to be performed over a period of time. The treatment had longevity with patient's knowledge about the necessity of oral hygiene and periodic controls.
