Two ordinal logit models are applied to fit the results of matches in the Brazilian football championship. As explanatory variables are employed measures of previous performance of the teamsalong all preceding games, along recent games and when playing at home and as a visitor. The results of the models adjustment are employed in simulations performed to forecast the number of points to be earnedin the following games and to anticipate the teams' final classification.

Aspect-oriented software development promotes improved separation of concerns by introducing a new modular unit, called aspect, for the modularization of crosscutting concerns. As a new kind of modular unit, aspects should have explicit interfaces that describe the way they interact with the rest of the system and how they affect other modules. This interaction can be homogeneous or heterogeneous. In this paper, we present crosscutting interfaces as a conceptual tool for dealing with the complexity of heterogeneous aspects at the design level. Crosscutting interfaces have been incorporated by the aSideML modeling language in order to enhance aspect description at the design level. Moreover, we present a modeling notation for the description of architecture-level aspects that also supports the explicit representation of crosscutting interfaces. Finally, we present two large-scale case studies we have performed using this modeling language that support our arguments in favor of crosscutting interfaces.

Design patterns offer flexible solutions to common problems in software development. Recent studies have shown that several design patterns involve crosscutting concerns. Unfortunately, object-oriented (OO) abstractions are often not able to modularize those crosscutting concerns, which in turn decrease the system reusability and maintainability. Hence, it is important verifying whether aspect-oriented approaches support improved modularization of crosscutting concerns relative to design patterns. Ideally, quantitative studies should be performed to compare object-oriented and aspect-oriented implementations of classical patterns with respect to important software engineering attributes, such as coupling and cohesion. This paper presents a quantitative study that compares aspect-based and OO solutions for a representative set of design patterns. We have used stringent software engineering attributes as the assessment criteria. We have found that most aspect-oriented solutions improve separation of pattern-related concerns, although some aspect-oriented implementations of specific patterns resulted in higher coupling and more lines of code.

OBJETIVO: Estabelecer a influência exercida pelos fatores climáticos na freqüência mensal da fauna de mosquitos em áreas do Parque Nacional da Serra da Bocaina, Vale do Paraíba, SP. MÉTODOS: Foram realizadas capturas mensais por meio de isca humana, em três diferentes períodos do dia, durante 24 meses consecutivos (janeiro de 1991 a dezembro de 1992). RESULTADOS: Foram capturados 11.808 espécimes adultos pertencentes a 28 espécies. Anopheles cruzii, Runchomyia reversa e Ru. frontosa foram as espécies mais presentes em todos os meses do ano; An. cruzii ocorreu preferencialmente de outubro a fevereiro; Ru. reversa e Ru. frontosa, em setembro; An. lutzi, Chagasia fajardoi, Coquillettidia chrysonotum, Aedes serratus, Trichoprosopon simile, Wyeomyia theobaldi, Ru. humboldti e Ru. theobaldi, pertencentes ao segundo grupo de espécies mais abundantes, ocorreram preferencialmente nos meses mais quentes, úmidos e chuvosos. A temperatura e as precipitações pluviométricas influenciaram positivamente na incidência da maioria das espécies. CONCLUSÕES: A cobertura vegetal de Mata Atlântica bem preservada, as precipitações pluviométricas e a temperatura foram determinantes para a incidência da fauna de mosquitos no parque. Os meses mais chuvosos, úmidos e quentes contribuíram para o aumento da diversidade e da densidade. O período de setembro a março foi o mais favorável. Cerca de 70% das espécies chegaram a desaparecer no período de abril a agosto, os meses mais frios e secos do ano.

OBJECTIVE: To establish the influence of climatic factors on the monthly frequency of mosquito fauna in areas of the National Park of Serra da Bocaina, Brazil. METHODS: Human bait collections were conducted once a month, in diurnal and nocturnal hours, throughout 24 months, from January 1991 to December 1992. RESULTS: A total of 11,808 adult mosquitoes belonging to 28 different species were collected. Anopheles cruzii, Runchomyia reversa, and Ru. frontosa were the most commonly found species each month. An. cruzii was found mostly from October to February; Ru. reversa and Ru. frontosa predominated in September. An. lutzi, Chagasia fajardoi, Coquillettidia chrysonotum, Aedes serratus, Trichoprosopon simile, Wyeomyia theobaldi, Ru. humboldti, and Ru. theobaldi are the second most prevalent species and they were found mostly throughout the hottest, rainiest and most humid months. Temperature and rainfall have positively influenced the incidence of the majority of the species. CONCLUSIONS: The exuberant and well-preserved tropical forest of Mata Atlântica, rainfalls, and temperatures had a direct and significant contribution to the mosquito fauna in the park. In the months with greater rainfalls, temperatures and humidity, there was an increase in the density and diversity of mosquito species. The period from September to March was the most favorable for their proliferation. In the colder and drier period, from April to August, about 70% of the species showed a significant decline in number, and they were hardly found during these months.

OBJETIVO: Estabelecer a influência exercida por três diferentes biótopos em áreas do Parque Nacional da Serra da Bocaina (PNSB) sobre a fauna local de mosquitos. MÉTODOS: Foram realizadas capturas mensais em ambiente silvestre e domiciliar, em isca humana, durante três diferentes períodos do dia, pelo período de 24 meses consecutivos, de janeiro de 1991 a dezembro de 1992. RESULTADOS: Foram capturados 11.808 espécimes adultos, pertencentes a 28 espécies. Ru. reversa e An. cruzii foram predominantes, respectivamente 52,5% e 17,9% do total de mosquitos. Ru. reversa representou 59,4% do total de espécimes no ambiente de mata fechada, seguida por Ru. frontosa com 10,5% e An. cruzii com 9,9%. No ambiente formado por campos de altitude e matas de galeria, o An. cruzii predominou com 48,1%, seguido por Ru. reversa com 28,1%. No ambiente modificado pelo homem, o An. cruzii predominou com 73,7% dos espécimes. Coquillettidia chrysonotum foi a única que se apresentou preferencialmente nesse biótopo: 14,9% no intra, 19,4% no peri e 65,7% no extradomicílio. An. cruzii e Ru. reversa foram constantes em todos os ambientes ao longo do ano. CONCLUSÕES: Com exceção de Cq. chrysonotum, com preferência pelo ambiente modificado pelo homem, os mosquitos apresentam hábitos assinantrópicos no PNSB. An. cruzii, embora assinantrópico, se aproxima e adentra o domicílio para realizar a hematofagia. A presença do Ae. serratus no extra e peridomicílio reforça a importância epidemiológica como vetora potencial de arboviroses. Os Sabethini apresentaram-se exclusivamente silvestres.

OBJECTIVE: To assess the mosquito fauna in Serra da Bocaina National Park (PNSB), by collecting information through a general survey, and investigating the population behavior in habitats within the park with different vegetation. METHODS: Human bait collections were conducted once a month for both the forest and households, in diurnal and nocturnal periods, three time a day, throughout 24 months, from January 1991 to December 1992. RESULTS: A total of 11,808 adult mosquitoes belonging to 28 species were collected. Runchomyia reversa and Anopheles cruzii were the most abundant, reaching 52.5% and 17.9% of the total collected specimens, respectively. In the dense forest, Ru. reversa comprised 59.4% of the total, followed by Ru. frontosa with 10.5%, and An. cruzii with 9.9%. In the high altitude fields and in gallery forest, An. cruzii was the most abundant (48.1%) followed by Ru. reversa (28.1%). Inside households An. cruzii was also the most prominent species, representing 73.7% of the total for that location. Coquillettidia chrysonotum was the only species mainly seen in the household surroundings, where its distribution was: 14.9% (indoors), 19.4% (close to the house), and 65.7% (outdoors). An. cruzii and Ru. reversa were found throughout the whole year and captured every month. CONCLUSIONS: Mosquitoes in PNSB present an assynanthropic behavior, except for Cq. chrysonotum which lives preferentially in the household environment. Though An. cruzii is an assynantropic species it may approaches live near households and even invades and infest them for the blood meals. The occurrence of Aedes serratus in the household vicinity emphasizes its epidemiological importance as a potential vector of arboviruses. Sabethini are all exclusively sylvatic species.

OBJETIVO: Avaliar, morfologicamente, por tomografia computadorizada espiral, enxertos de pericárdio bovino liso empregados como substitutos aórticos. MÉTODOS: Dez pacientes foram submetidos a exame por tomografia computadorizada espiral para reconstituição da imagem dos enxertos. Os critérios de seleção foram tempo de seguimento superior a 2 anos, enxertos de pericárdio liso não revestido, implantados na aorta ascendente ou descendente. RESULTADOS: Os exames demonstraram bom resultado cirúrgico em todos os casos, persistindo em alguns, a imagem de dissecção aórtica distal à anastomose. Um caso apresentava hematoma entre o enxerto e a parede aórtica, em 5 não foram encontradas alterações estruturais no pericárdio e, nos demais, foi detectada dilatação de grau leve, em relação ao diâmetro descrito do enxerto implantado. Não foram vistos sinais de calcificação ou pseudoaneurismas. CONCLUSÃO: Os enxertos tubulares de pericárdio bovino liso, não revestido, apresentam resultados satisfatórios quando empregados como substitutos aórticos. A médio prazo, não foram detectadas anormalidades estruturais relacionadas ao material empregado, pela tomografia computadorizada espiral, exceto dilatação em alguns casos.

PURPOSE: To evaluate morphologically by spiral computed tomography (SCT) bovine pericardial grafts as aortic substitutes. METHODS: Ten patients were submitted to aortic graft evaluation with SCT. There were 8 ascending and 2 descending grafts. Examination was done after 2 to 7 years post operative. Ages ranged from 49 to 67 years, with 6 male and 4 female patients. All had implanted smooth surface naked pericardial grafts. RESULTS: Surgical result was good in all. Distal dissection persisted in some cases. One had a peri-graft hematoma, 5 had no structural changes and 4 presented mild graft dilatation. There were no graft calcification or pseudoaneurysm. CONCLUSION: Glutaraldehyde preserved naked smooth surface bovine pericardial aortic grafts present satisfactory structural aspect, as seen by SCT, at medium term follow-up. Mild dilatation may be seen in some cases.
