ABSTRACT This study analyzed the productive strategies and technology of beef producers in the Vermelho basin in Goiás, Brazil. The data were used to develop a technological index, applicable to the local beef production systems. The data were obtained using questionnaires. A set of 60 properties was selected to provide a representative sample of the relief and soil quality within the study area. The data were analyzed using multiple correspondence, cluster analysis, and beta regression procedures. The variables that most contributed to the definition of the technological level were identified. The variables and production units each formed three clusters, corresponding to three levels of technology: low, mid, and high. The data were used to calculate a predictive index for the analysis and mapping of the technology used in the study area. High cattle densities were found in systems with low technology, indicating low productivity and profitability, and reduced environmental sustainability.

Procurou-se determinar o prognóstico de pacientes neuróticos em tratamento ambulatorial mediante o cálculo das probabilidades de "melhora", "piora" e "inalteração" em consultas sucessivas. Foi, assim, analisada a evolução de 157 pacientes de 20 a 59 anos que entraram para o estudo em um ponto qualquer durante um período de observação de 12 meses.

The prognosis of neurotic patients followed on a outpatient service was determined by calculation of probabilities of "improvement", "worsening" or "lack of changes" on successive examinations. These criteria were established for evaluation of 157 patients, 20 to 59 years old, who entered the study during a 12 months observation period.
