We present a prototype system to be used for visually accessing heterogeneous databases. The basic idea is to provide the user with several visual representations of data as well as multiple ...interaction mechanisms for both querying databases and visualizing the query results. Since some visual representations better fit certain user classes, the system adapts to the user's needs by switching to the most appropriate visual representation and interaction mechanism, according to a suitable user model. The data and query representations are consistent in every paradigm. Such a notion of consistency stems from formal basis, i.e. a twofold data/representation model, namely the Graph Model, and a set of basic Graphical Primitives. This formal approach allows the user to switch from one interaction paradigm to another, always saving the query state.
The objective of this study is to describe infections in a specialized burns intensive care unit from 1993 to 1999. The criteria for admission to the unit are: children with burns involving at least ...10% or adults with burns involving at least 20% of total body surface; burns affecting face, perineum or feet; suspected or proven airway injury; electric or chemical burns; age less than one year or above 50; or pre-existing disease with any extent of burns. Surveillance of hospital-acquired infection was prospective. Hospital-acquired infection criteria used were those modified from the Centers for Disease Control and Prevention. Diagnosis of infection using skin biopsy was not done. Over the study period, 320 patients were admitted to our burns intensive care unit. One hundred and seventy-five (55%) developed 388 hospital-acquired infections. The rate for vascular catheter-associated bloodstream infections was 34 per 1000 central line-days. The rate of ventilator associated pneumonia was 26 infections per 1000 ventilator-days. Primary bloodstream was the most common infection with 189 episodes (49%); followed by 83 burn wound infections (21%) and 56 pneumonias (14%). In 76% of these infections and in 97% of the primary bloodstream infections, aetiological agents were identified. The micro-organisms causing infections were S taphylococcus aureus (24%), Pseudomonas aeruginosa (18%),Acinetobacter spp. (14%) and coagulase-negative staphylococci (12%). Candida spp. caused 8% of infections. Gram-positive and Gram-negative organisms exhibited resistance to most antimicrobial agents used for therapy. During the first three days of hospitalization in the burns intensive care unit there were eight infections caused by S. aureus and three of these were resistant to oxacillin. These data provide background information regarding extensive burn patients on which decisions for control and prevention of hospital-acquired infections can be made.

Conference Proceeding
The International Conference on Web Information Systems Engineering (WISE), held in Rome, 10-13 December 2003, hosted three satellite workshops, on Web and Wireless Geographical Information Systems ...(W2GIS), Web Services Quality (WQW), and Multichannel and Mobile Information Systems (MMIS), respectively. This volume contains the joint workshops proceedings and includes 30 high-quality papers (the overall workshop acceptance rate was about 50%). In particular, the W2GIS workshop selected 12 papers and a keynote talk, the WQW workshop selected 9 papers, and the MMIS workshop selected 9 papers. The papers presented in this volume have been revised by the authors, according to the useful workshop attendees' feedback.

We report the results from a search in Super-Kamiokande for neutrino signals coincident with the first detected gravitational wave events, GW150914 and GW151226, using a neutrino energy range from ...3.5 MeV to 100 PeV. We searched for coincident neutrino events within a time window of \(\pm\)500 seconds around the gravitational wave detection time. Four neutrino candidates are found for GW150914 and no candidates are found for GW151226. The remaining neutrino candidates are consistent with the expected background events. We calculated the 90\% confidence level upper limits on the combined neutrino fluence for both gravitational wave events, which depends on event energy and topologies. Considering the upward going muon data set (1.6 GeV - 100 PeV) the neutrino fluence limit for each gravitational wave event is 14 - 37 (19 - 50) cm\(^{-2}\) for muon neutrinos (muon antineutrinos), depending on the zenith angle of the event. In the other data sets, the combined fluence limits for both gravitational wave events range from 2.4\(\times 10^{4}\) to 7.0\(\times 10^{9}\) cm\(^{-2}\).
Three experiments were conducted on 90 flying personnel to determine the role of luminance, hue, and saturation contrasts on angular visual acuity measured on a CRT system. A Snellen E test object ...was displayed under various visual acuity conditions on a TV screen, in color contrast, using red, yellow, green, cyan, blue, purple, white, and black. The response system gives response times and quality. The three photocolorimetric parameters are classified through data processing. All other things being equal, the best visual acuity is obtained under a luminance contrast. Two groups of colors can be differentiated under a hue contrast. The first group (red, blue, purple) is better perceived than the second (green, cyan, yellow, white) whatever the other color in simultaneous contrast may be. Higher saturation enhances visual acuity. A curve of mean response time vs. test object sizes is established for the various color couples. The obtained results are of interest for aerospace ergonomics.
