To adopt the use of home-based cardiac tele-rehabilitation, it is necessary to assess cardiac patients＇ attitudes towards acceptance of such e-health technology, especially in China where knowledge of such technology is deficient. Methods Interviews were conducted in the First Affiliated Hospital of Shantou University Medical College, Shantou, China. After percutaneous coronary interventional （PCI） surgery, patients completed the survey. Results Among the 150 patients, only 13% had ever heard of HBCTR. After an introduction of our HBCTR program, 60% of patients were willing to participate in the program. From our multivariate analysis of questionnaire data, age （OR： 0.92, 95% CI： 0.864）.98; P = 0.007）, average family monthly income （OR： 0.13, 95% CI： 0.05-0.341 P 〈 0.001）, education level （OR： 0.24, 95% CI： 0.10-0.59; P = 0.002） and physical exercise time （OR： 0.19, 95% CI： 0.06-0.56; P = 0.003） were independent predictors for acceptance of HBCTR. From the reasons for participation, patients selected： enhanced safety and independ ence （28.3%）, ability to self-monitor physical conditions daily （25 A%）, and having automatic and emergency alert （23.1%）. Reasons for refusal were： too cumbersome operation （34.3%） and unnecessary protocol （19.4%）. Conclusions Most patients lacked knowledge about HBCTR but volunteered to participate after they have learned about the program. Several personal and life-style factors influenced their acceptance of the program. These indicate that both improvement of technology and better understanding of the program will enhance active participation.展开更多

In order to be used in subsequent quantitative analysis and assessment, this data should be subject to preliminary processing aiming to improve its accuracy and credibility. The paper considers some major problems related with preliminary processing of remotely sensed spectral data and images. The major factors are analyzed, which affect the occurrence of data noise or uncertainties and the methods for reduction or removal thereof. Assessment is made of the extent to which available equipment and technologies may help reduce measurement errors.展开更多
