Geospatial Information Visualization User Interface Issues

User interfaces for geospatial information are the tools by which users interact with and explore that information. The provision of appropriate interface tools for exploiting the potential of contemporary geospatial visualization products is essential if they are to be used efficiently and effectively. This paper addresses issues and challenges in interface development and usage that are identified as paramount within the geospatial visualization community.

Antigranulocyte scintigraphy of septic loosening of hip prosthesis: influence of different analyzing methods

Summary Aim: Diagnosis of infection with help of antigranulocyte scintigraphy near body stem is difficult because of contemporary visualisation of bone marrow. Therefore, we investigated, whether it is possible to improve the accuracy in diagnosing septic loosening of hip endoprosthesis by changing the analyzing methods. Methods: In 28 patients, the results of a visual interpretation of late scan, a visual interpretation and a quantitative interpretation of time-activity-course were compared. These results were verified by histology respectively microbiology. Results: Histological and microbiological verification found 14 septic loosening and 14 aseptic loosening of the hip protheses. Therefore, sensitivity, specifity, negative and positive predictive value for the visual interpretation of late scan were 0.86,0.57,0.80 and 0.67. For visual and quantitative interpretation of time-activity-course we found 0.86,0.79,0.85 and 0.80 respectively 1,0.93, 1,0.93. For interobserver agreement we found kappa coefficients of 0.28 ± 0.2 for visual interpretation of late scan, 0.48 ±0.17 for visual interpretation and 1.0 ± 0 for quantitative interpretation of time-activity-course. Conclusion: In all investigated values quantitative interpretation of time-activity-course was superior to the other analyzing methods. Therefore, antigranulocyte scintigraphy for septic loosening of hip endoprosthesis should be interpreted quantitativly.

Photography and the Self

CIRCA: Irish and International Contemporary Visual Culture commission to create a new piece of theory led photographic practice. This consisted of a critical academic essay on photography and psychoanalysis and four pages of full colour digital art photographs.

Redefinindo o Conceito de Imagem

O que é a imagem hoje? A coexistência de diferentes tipos de imagem não permite mais conceder primazia à representação, alicerçada na relação entre imagem e realidade exterior. O modelo, fruto de abstrações formais, está tomando cada vez mais o lugar da imagem especular, marcando a passagem da natureza para a linguagem e redefinindo o regime da visualidade contemporânea.
