“…It has also been shown that, at least under some circumstances, information can be found using computer systems and a limited amount of resources [8,9]. According to Lindberg et al, literature retrieval systems such as MEDLINE may be used by health care providers to meet clinical information needs [10], but according to Williamson et al [3] many physicians (38%) nd the eå ort necessary to get information from the literature to be a major problem. Other problems mentioned are nding time to look for information and sorting out irrelevant material.…”

The objective of this study was to examine a design for a World Wide Web-based decision-support system in use by clinically active physicians. A prototype implementation of the design concerned management of infective endocarditis patient cases. The design was based on an integration of hypertext and rule-based knowledge. In the study sessions, physicians in the field of internal medicine worked on managing authentic patient cases in a laboratory setting. Data was collected from interviews with the physicians using video recordings and stimulated recall technique. The qualitative data was analysed according to the constant comparative method in order to develop a model of the physicians' usage of the system. The resulting model describes perceived contributions and criteria for usefulness of the system. The ways the physicians used the system showed that it was able to provide patient-specific support for confirming clinical decisions, for higher-level patient management, and for preparing for and initiating expert consultations. Users also stated that new medical knowledge could be gained as a side effect of using the system.

“…22 A correlation matrix of all studied variables was performed to recognize previous relationships among the metals concentration and cluster analysis was used to identify and study the interrelationships among variables (metals) and sites with similar behaviors. These statistical analyses were carried out using SSPSS 11.0 software package for Windows.…”

A contaminação por metais em 47 amostras de sedimentos (fração < 63 µm) coletadas em 13 pontos de pesca no reservatório Billings foi avaliada utilizando quatro metodologias: normas de qualidade de sedimentos (SQG S ), índice de geoacumulação (I Geo ), índice de poluição metálica (MPI) e análises estatísticas. Somente Fe e Co parecem estar associados com a composição natural do sedimento ou processos de intemperismo natural, enquanto Al, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn mostraram aumento em suas concentrações, sugerindo associação com fontes antropogênicas. MPI identificou as áreas mais críticas em relação à concentração total de metais enquanto I Geo identificou o metal específico para cada área. A sazonalidade sobre os níveis dos metais foi avaliada usando análise de variância (ANOVA) e gráfico de caixa. Somente o gráfico de caixa sugeriu um pequeno aumento na contaminação por Hg and Pb durante o período com muita chuva e também indicou altas concentrações de Cu e Zn em um dos pontos analisados com a incidência de valores fora do normal e extremos. Portanto, políticas ambientais devem ser adotadas para reduzir a contaminação por metais.Four approaches were applied to evaluate the metal contamination in 47 sediment samples (< 63 µm fraction) collected at 13 fishing points of the Billings Reservoir: sediment quality guidelines (SQGs), geoaccumulation index (I Geo ), metal pollution index (MPI) and statistical analyses. Only Fe and Co concentrations seemed to be associated with crustal material or natural weathering processes, while Al, Cd, Cr, Cu, Hg, Mn, Ni, Pb and Zn showed increases in their concentrations, which seemed to be associated with anthropogenic sources. MPI identified the most critical sites in relation to the total metal accumulation while I Geo identified the specific metal accumulation for each site. Analysis of variance (ANOVA) and box plot method were performed to evaluate seasonal effects on the metal levels. Only box plot suggested a slight increase in Hg and Pb contamination during heavy rainy periods and also indicated high concentrations of Cu and Zn in one of the analyzed point, with incidence of outliers and extreme values. Thus, an environmental policy in order to reduce these metal contaminations must be adopted.

“…Survey methodology is popular in studying large medical populations (Stinson & Muller, 1980;Strasser, 1978;Williamson, German, Weiss, Skinner, & Bowes, 1989). For example, Stinson and Muller interviewed 400 randomly selected Alabama health professionals in an effort to identify "the information habits health professionals used to stay abreast of current advances in medicine.…”

The objective of this study was to characterize the types of tissue-centric users based on tissue use, requirements, and their job or work-related variables at the University of Pittsburgh Medical Center (UPMC), Pittsburgh, PA. A self-reporting questionnaire was distributed to biomedical researchers at the UPMC. Descriptive and cluster analyses were performed to identify and characterize the complex types of tissue-based researchers. A total of 62 respondents completed the survey, and two clusters were identified based on all variables. Two distinct groups of tissue-centric users made direct use of tissue samples for their research as well as associated information, while a third group of indirect users required only the associated information. The study shows that tissue-centric users were composed of various types. These types were distinguished in terms of tissue use and data requirements, as well as by their work or research-related activities.

Abstract: Primary practitioners require substantial help in meeting current science information needs. Increase in such resources as "validated reviews" or "expert networks" might help meet these needs.
