Método monoscópico para a determinação automática da altura de edifícios em fotografias aéreas

This paper proposes a monoscopic method for automatic determination of building's heights in digital photographs areas, based on radial displacement of points in the plan image and geometry at the time the photo is obtained. Determination of the buildings' heights can be used to model the surface in urban areas, urban planning and management, among others. The proposed methodology employs a set of steps to detect arranged radially from the system of photogrammetric coordinates, which characterizes the lateral edges of buildings present in the photo. In a first stage is performed the reduction of the searching area through detection of shadows projected by buildings, generating sub-images of the areas around each of the detected shadow. Then, for each sub-image, the edges are automatically extracted, and tests of consistency are applied for it in order to be characterized as segments of straight arranged radially. Next, with the lateral edges selected and the knowledge of the flight height, the buildings' heights can be calculated. The experimental results obtained with real images showed that the proposed approach is suitable to perform the automatic identification of the buildings height in digital images.

Predição de sombras de edifícios sobre vias urbanas com base em modelos digitais de elevações e dados de imagens aéreas de alta resolução

This research presents a methodology for prediction of building shadows cast on urban roads existing on high-resolution aerial imagery. Shadow elements can be used in the modeling of contextual information, whose use has become more and more common in image analysis complex processes. The proposed methodology consists in three sequential steps. First, the building roof contours are manually extracted from an intensity image generated by the transformation of a digital elevation model (DEM) obtained from airborne laser scanning data. In similarly, the roadside contours are extracted, now from the radiometric information of the laser scanning data. Second, the roof contour polygons are projected onto the adjacent roads by using the parallel projection straight lines, whose directions are computed from the solar ephemeris, which depends on the aerial image acquisition time. Finally, parts of shadow polygons that are free from building perspective obstructions are determined, given rise to new shadow polygons. The results obtained in the experimental evaluation of the methodology showed that the method works properly, since it allowed the prediction of shadow in high-resolution imagery with high accuracy and reliability.

Uso de dados fotogramétricos no refinamento geométrico de contornos de telhados de edifícios extraídos de dados laser

In this paper, a methodology is proposed for the geometric refinement of laser scanning building roof contours using high-resolution aerial images and Markov Random Field (MRF) models. The proposed methodology takes for granted that the 3D description of each building roof reconstructed from the laser scanning data (i.e., a polyhedron) is topologically correct and that it is only necessary to improve its accuracy. Since roof ridges are accurately extracted from laser scanning data, our main objective is to use high-resolution aerial images to improve the accuracy of roof outlines. In order to meet this goal, the available roof contours are first projected onto the image-space. After that, the projected polygons and the straight lines extracted from the image are used to establish an MRF description, which is based on relations ( relative length, proximity, and orientation) between the two sets of straight lines. The energy function associated with the MRF is minimized by using a modified version of the brute force algorithm, resulting in the grouping of straight lines for each roof object. Finally, each grouping of straight lines is topologically reconstructed based on the topology of the corresponding laser scanning polygon projected onto the image-space. The preliminary results showed that the proposed methodology is promising, since most sides of the refined polygons are geometrically better than corresponding projected laser scanning straight lines.

Condição microbiológica dos leitos hospitalares antes e depois de sua limpeza

INTRODUÇÃO: O meio ambiente hospitalar guarda uma íntima relação com as infecções hospitalares, podendo proporcionar focos de contato e de transmissão. Como a higiene representa uma das formas de controlar a contaminação ambiental, realizou-se estudo para avaliar as condições microbiológicas dos colchões hospitalares antes e depois de sua limpeza. MÉTODOS: Utilizaram-se, para a colheita dos espécimes, placas de contato -- Rodac-plate ¾ preparadas com meio de cultura ágar-sangue. Selecionaram-se os leitos de acordo com critérios previamente estabelecidos, e os locais de colheita sob o colchão foram escolhidos por sorteio aleatório. Aplicou-se o teste estatístico de Goodman para o estudo das alterações numéricas quanto a positividade das placas. RESULTADOS: Foram investigados 52 colchões, totalizando 520 placas, das quais 514 (98,8%) resultaram em culturas positivas, sendo que 259 corresponderam ao período anterior à limpeza e 255 ao período posterior ao procedimento. Houve redução de culturas positivas em apenas 4 placas. CONCLUSÕES: Os resultados obtidos sugerem que a limpeza, da forma como vem sendo conduzida, provoca o deslocamento da carga microbiana para outros pontos do colchão em vez de diminuí-la, resultando na manutenção da quantidade de microorganismos que existia anteriormente à limpeza.

Atividade comparada da cefepima, cefpiroma e amicacina em amostras bacterianas hospitalares

The objective of this study was to evaluate the in vitro activity of cefepime, cefpirome and amikacin against the most prevalent nosocomial bacteria. Initially a prospective study was designed to compare the bacterial susceptibility to the three drugs using 1,022 pathogenic strains. The strains were isolated from hospitalized patients of the Hospital das Clinicas - Faculdade de Medicina de Botucatu, SP, from March to December of 1996, by using the Bauer-Kirby susceptibility diffusion controlled method. The activity of cefepime by the Kirby-Bauer method was significantly higher (χ2, p ≤ 0.05) than cefpirome and amikacin for the following bacteria: P. aeruginosa (72% x 56% x 64%, respectively), Enterobacter cloacae (98% x 88% x 80%) and total strains (79.5% x 74.3% x 76.8%). Cefpirome exhibited higher activity than cefepime only to Enterococcus faecalis (42% x 23%). In the 12 other bacterial groups studied the sensibility of the three drugs was similar (χ2, p ≥ 0.05). The minimal inhibitory concentration (MIC) for 127 bacterial strains - Enterobacter cloacae (12), Citrobacter sp (15), Pseudomonas aeruginosa (50), Acinetobacter baumannii (12), BGNF others (22) and Enterococcus faecalis (16)-from the same origin previously described and isolated during 1997, was determined by E-test. Ranges of MIC intervals, MIC(50%), MIC(90%) and the proportion of the sensitive bacterial strains were determined and permitted the following analysis: the activity of cefepime against Gram-negative bacteria was 2 or more times higher than that of cefpirome and amikacin, specially when CIM(90%) was considered; the activity of cefpirome was higher only against E. faecalis. This information must be considered in the rational use of antibiotic, specially in patients with nosocomial infections.

Ocorrência e determinação do perfil de sensibilidade às drogas das cepas de Staphylococcus aureus isoladas de fossas nasais e orofaringe dos servidores hospitalares

Staphylococcus aureus is a very important hospital and community pathogen. This species is related to supurative disease, systemic and widespread metastatic lesions. The ability of S. aureus to develop resistance to antibiotics, more recently to methicillin, associates this bacteria with epidemic outbreaks of severe nosocomial infection. The source of staphylococcal infection is a patient with a staphylococcal lesion or a career member of the hospital staff. We aimed to detect the frequency of S. aureus isolated from anterior nares and oral cavities among the hospital staff in Bauru - SP, and to determine the antibiotic susceptibility of the isolates. Within 213 of the staff members analyzed. S. aureus was found in 94 (44.13%) of careers, with 47 (50%) of nasal carriers, 23 (24.4%) of oral carriers and 24 (25.5%) of both carriers. The biochemical characteristics analyzed for the species identification were similar to S. aureus ATCC 29213. All strains identified as S. aureus showed varied sensibility to the antimicrobial agents tested. No vancomicin resistant strains and only 8 (8.5%) strains with oxacilin resistance were found.
