Eficiência das companhias aéreas brasileiras: uma análise envoltória de dados

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

Curcumina: de especiaria à nutracêutico

A ideia de uma nutrição que, além de suprir as necessidades nutricionais básicas do organismo também tem como objetivo a prevenção de doenças, ganha cada vez mais ênfase sobre a égide dos alimentos funcionais e dos nutracêuticos. Nesse contexto a curcumina, um pigmento amarelo-alaranjado extraído do rizoma da planta Curcuma longa L. se destaca como um promissor nutracêutico, apresentando um amplo potencial terapêutico e a cada dia encontra maior embasamento científico com a elucidação de seus mecanismos de ação sobre vários alvos moleculares importantes para a fisiopatologia de diversas doenças. A curcumina é bastante conhecida e explorada pela medicina asiática tradicional, principalmente pelas medicinas Ayurvédica e Chinesa. Utilizando o Pubmed e o Scielo como banco de dados para a pesquisa de trabalhos científicos, foi elaborada uma revisão bibliográfica com a compilação de estudos com diversos enfoques em relação à curcumina, a saber: i) características físico-químicas da curcumina; ii) propriedades anti-inflamatória, antioxidante, antidiabética, antitumoral, antiviral, antibacteriana, antiparasitária e antifúngica; iii) estratégias recentemente utilizadas para melhorar sua biodisponibilidade, tais como co-admnistração da piperina, síntese de análogos moleculares e sistemas inovadores de entrega como os sistemas coloidais (lipossomas e nanopartículas) e a complexação com ciclodextrina.

Utilização de SIG na sistematização de ocorrências de trauma no SAMU-192 das cidades de Feira de Santana BA e Rio Claro SP

Considering current technological progresses, they prove to be useful tools to be increasingly exploited in order to meet the population's needs. Generally, in Brazil, the Mobile Emergency Services (SAMU) tend to be limited to the management of incidents, which undermines the efficiency of these bodies. In this context, this final dissertation aims to present the use of Geographic Information Systems (GIS) for the SAMU in the cities of Feira de Santana BA and Rio Claro SP, integrating occurrences data related to trauma by cold weapon injuries, injury by gun, and assaults, in the period 2012-2013, as well as census data. The study was developed in stages that included obtaining data related to trauma events linked to urban violence, and statistical Census data (2010), provided by the Brazilian Institute of Geography and Statistics (IBGE). Regarding the GIS, the free software Quantum GIS (QGIS) was adopted for processing and spatializing data, assuming the districts as units of study, in the urban area of the cities analyzed. The resulting research products were presented in thematic maps format, which conducted to a comparative analysis of the occurrences related to traumas. The achieved results were satisfactory, and a database in GIS was developed, integrating occurrences data by Cold Weapon Injuries (FAB), Injury by Gun (FAF) and Assaults with census data, allowing the proper use and update of the system. Making a comparative analysis between the two cities, it was possible to establish that Rio Claro presents more occurrences when it comes to FAF, FAB and Aggression recorded at SAMU per 100,000 inhabitants than Feira de Santana. Thus, although Rio Claro's population is about three times smaller than Feira de Santana's, it can be said that Rio Claro is a more violent city, considering the factors analyzed. It is possible to infer that the use of GIS applied to the SAMU in medium-sized cities is feasible, and it has the advantage...

Queixas técnicas e eventos adversos a medicamentos notificados em um hospital sentinela do interior de São Paulo, 2009-2010

Objective: to describe technical complaints and adverse drug events reported in a sentinel hospital in São Paulo state in 2009 and 2010. Methods: This is a descriptive study. Information was obtained from the sentinel hospital Risk Management database. Results: we found 199 reports related to drugs: 70.0% were technical complaints, 21.0% ineffective therapy and 9.0% adverse reaction to medication. The pharmacological groups with highest number of reports were: drugs that act on alimentary tract and metabolism (25.1%), the nervous system (25.1%) and anti-infective drugs for systemic use (22.1%). Conclusion: technical complaints and adverse drug events were frequent, despite recognized underreporting. The characterization of these events could inform the adoption of control measures and permanent educational actions in health services in order to prevent their occurrence.

Aplicação de análise multicriterial para determinação de áreas prioritárias à recomposição florestal

Using the Geographic Information System (GIS) and taking into account its capability to analyze spatial data, a database of updated spatial data from the sub-basin of the Descalvado stream, Botucatu, SP, was developed to provide an evaluation and diagnosis of the area concerning land use and the degradation processes therein. Through GIS, priority areas for forest recovery were defined by Multicriteria Evaluation and using the Ordered Weighted Average method. The latter allows the decision maker to define the area to be recovered, facing limitation of resources, among one of the proposed scenarios, or do it in stages. The study showed that there are accelerated erosion processes in the headwaters of the springs of water bodies; there is also fragmentation of native vegetation, especially in hillside areas, and little presence of native vegetation in riparian areas. The application of the multicriteria analysis using the Ordered Weighted Average was important as it systematized and discriminated scenarios of priority for forest recovery.
