This study aimed to define the relationship between the physical activity level (PAL) and adult Saudi health-related quality of life (HRQoL). Methods: Participants of this study were 100 Saudi adult aged from 18 - 70 years. The 36-Item Short-Form Health Status Survey (SF-36) was used to measure the participant’s HRQoL. The SF-36 is comprised of 8 domains. The electronic version of the General Practice Physical Activity Questionnaire was used to categorize participants in terms of physical activity level into;inactive, moderately inactive, moderately active, and active. Descriptive and inferential statistical tests were used to treat the collected data. Results: Results showed that only 17% of the Saudi adults had active PAL. The PAL had significantly positive relationship with 4 domains of HRQoL including: physical functioning (P = 0.004), role limitations caused by physical health problems (P = 0.048), vitality (P = 0.009), and general health (P = 0.044). Results also confirmed that the younger the subject, the higher the PAL (P = 0.0001) and the better the HRQoL. This is true for all domains except the role limitations caused by emotional problems and emotional wellbeing. Conclusion: The poor physical activity level of adult Saudi negatively impacts their HRQoL.展开更多

There are a considerable number of approaches which require an initial data about the 3D ob- ject such as boundary conditions （BC）. However, it is difficult to obtain these information for each point of the object Edge in the image, thus the application of these approaches is lim- ited. This paper shows an improvement of the Global View method proposed by Zhu and Shi [1]. The main improvement is that we make the resolution done automatically without any additional information on the 3D object. The method in- volves four steps. The first step is to determine the singular curves and the relationship between them. In the second step, we generate the global graph, determine the sub-graphs, and determine the partial and global configuration. The proposed method to determine the convexity and the concavity of the singular curves is applied in the third step. Finally, we apply the Fast-Marching method to reconstruct the 3D object. Our approach is successfully tested on some synthetic and real im- ages. Also, the obtained results are compared and discussed with some previous methods.展开更多
