To understand and identify their optimal habitat, we have developed a habitat suitability index (HSI) model using two potential important environmental variables - sea surface temperature (SST) and sea surface height anomaly (SSHA) - and fishery data from the main fishing ground (165°-180°E) during June and July of 1999-2003. A geometric mean model (GMM), minimum model (MM) and arithmetic weighted model (AWM) with different weights were compared and the best HSI model was selected using Akaike's information criterion (AIC). The performance of the developed HSI model was evaluated using fishery data for 2004. This study suggests that the highest catch per unit effort (CPUE) and fishing effort are closely related to SST and SSHA. The best SST- and SSHA-based suitability index (SI) regression models were SISST-based = 0.7SIeffort-SST + 0.3 SICPUE-SST, and SISSHA-based = 0.5SIeffort-SSHA + 0.5SICPUE-SSHA, respectively, showing that fishing effort is more important than CPUE in the estimation of SI. The best HSI model was the AWM, defined as HSI=0.3SISST-based+ 0.7SISSHA-based, indicating that SSHA is more important than SST in estimating the HSI of squid. In 2004, monthly HSI values greater than 0.6 coincided with the distribution of productive fishing ground and high CPUE in June and July, suggesting that the models perform well. The proposed model provides an important tool in our efforts to develop forecasting capacity of squid spatial dynamics.展开更多

The present study aimed to assess the risk of falls of patients with sequelae of stroke using Tinetti Index. Methods: Transversal descriptive study with 61 hospitalized patients. The data were collected through the application of Tinetti Index, the total score of which is 28 points. Results: The index evaluation shows que 47.9% had 19 points under the ideal score, indicating a high risk of falls, 41.7% from 24 to 28, indicating moderate risk and 10.4% from 19 to 23 points, indicating low risk of falls. The final average was (15.23), the median (16.50) and standard deviation (±11.034). Conclusions: There is a high risk of falls in this population, a quantification of impaired balance and gait anticipate the future risk of falls. The use of assessment instruments has important implications for improving the quality of life in patients with symptomatic stroke.展开更多
