Classificação de workflows baseados em web services

Over the last decades changes have occurred in communication within and between enterprises, made easier by technologies suchas E-commerce, Internet, ERP systems and remote meetings and there was a rapid progress in network technology, which has changed the way business is done. A standardized way to offer services over the internet is using web services. Web services are a kind of remote procedure call and are generally used to integrate systems, independent of language, both client and server. It is common to use several web services run in sequence to perform a business process. To this type of process, gives the name of workflow. Thus, Web services are the primary components of workflows. A tool that provides a way of visualizing the behavior of a workflow can assist the administrator and is required. The present work presents the development of a tool that allows the administrator to classify visually services components and evaluate their importance in the final performance of a workflow. As proof of concept we used several virtual servers and computers where each computer has received a set of web services. A proxy was added between each call of workflows collecting relevant information and storing them in a database for later analysis. The analysis was based on Quality of Service parameters

Monitoramento espacial e análise das características climáticas na influência sobre a cultura de soja no estado do Paraná

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost

Avaliação de atributos do solo e vegetação em sistema agroecológico

A importância da agroecologia se dá no sentido de fornecer e ser, base e estrutura de conhecimentos mesclados, incorporando saberes tradicionais aos saberes técnicos científicos atuais, sem excluir ou rejeitar, mas usando ambos a favor da transição para uma pratica agrícola mais sustentável e coerente com os fluxos e com a complexidade natural de um ecossistema, o que não se percebe nas práticas agrícolas modernas e convencionais. Inúmeros estudos constataram que para uma boa efetividade de sistemas agroecológicos é necessário recuperar e manter o equilíbrio biológico do solo, pois isso influenciará em suas características físicas e químicas. O objetivo desse trabalho foi de caracterizar o solo sob Sistema Agroflorestal (SAF) e uma Pastagem, no município de Rio Claro (SP), para a obtenção de atributos do solo, morfológicos, físicos e químicos e também descrever a diversidade do extrato arbóreo presente na área, incluindo as espécies agrícolas, e levantar o histórico de implantação do sistema, de modo a criar e dar início a formação de um banco de dados científicos para o Grupo de Extensão Gira-Sol. Foram escolhidos dois perfis nas seguintes situações: sistema agroflorestal e uma Pastagem para descrição morfológica do solo. Em cada área foi efetuada a coleta de amostras deformadas e indeformadas e caracterizados os atributos granulometria, analises química, densidade do solo, porosidade do solo e resistência à penetração. Para a descrição morfológica dos perfis foi utilizado os procedimentos descritos por Lemos e Santos (2002), para os atributos químicos e de fertilidade do solo, Camargo et al. (1986) e EMBRAPA (1997), para granulometria, densidade e porosidade do solo e argila dispersa em água. A descrição da vegetação foi feita com auxilio de guias de identificação e por meio de parcelas, onde as espécies foram tabeladas e plotadas em um mapa da área para localização das mesmas, e.

Concepção e Implementação de um Sistema de Controle de Arborização Urbana através da Integração de Softwares Livres e de Código Aberto

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

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

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.

Conhecimento odontológico de adultos atendidos em uma unidade de saúde da família do município de São Carlos, Brasil

The Family Health Strategy is a primary care public policy that is becoming a decisive step towards the transformation of the Brazilian healthcare model. This study evaluated the dental knowledge among individuals who attended a Family-Health Unit (FHU) in the city of São Carlos, SP, Brazil. Methods: The evaluation was based on a questionnaire with 20 questions about oral health, prevention and development of dental caries and periodontal disease. The questionnaire was given to 168 individuals, over 18 years of age and both sexes, to fill out under the supervision of a trained dentist. After data collection, the answers contained in the original questionnaires were entered into a database built using the program Excel® (Microsoft Corporation, USA) and a descriptive statistical analysis was done. Results: 66.67% of the subjects reported having received information about dental caries and periodontal disease before attending the FHU, and dentists were cited as the main source of such information (60.71%). With regard to dental caries, 70.24% of the individuals stated that they knew about the subject, but the majority of answers revealed incorrect explanation of it. The multifactorial etiology (bacteria/sugar/poor hygiene) was not mentioned. A low percentage of subjects (24.40%) claimed to know what periodontal disease is, and of these, the highest percentage of responses was related to gingivitis (26.83%) and gingival bleeding (12.20%). Out of all subjects, 80.36% affirmed that oral hygiene is important, and among them, the main reasons cited were the maintenance of oral health (29.63%), to avoid diseases (16.30%) and to preserve and prevent disease (14.81%). Conclusion: Responses from the questionnaires revealed deficient dental knowledge among the individuals. To improve the understanding about this issue, the information obtained through the questionnaire can be used to develop educational programs that will focus specifically on the major deficiencies found.
