Hence, this study was performed in order to examine the impact of family-based behavioral treatment compared with Barkley behavior therapy in reducing symptoms of children with attention deficit disorder—ADHD. To meet the aim, 20 of children with age range of 7 to 12 years old with attention deficit disorder—hyperactivity were selected in both experimental and control groups, and exposed to the treatment of behavioral family therapy groups and changes in behavior Barkley. Before and after the treatment, they were evaluated according to the scale of the Conner’s Parent Rating Scale-Revised Short Form (CPRS-R: S). Results of multivariate analysis of covariance indicated that there were significant differences between the experimental group who had received family-based behavioral treatments based on changes in behavior Barkley and a control group who had received drug treatment in variables, including conduct problems, learning problems, psychosomatic symptoms, and signs of impulsive hyperactivity, anxiety and hyperactivity (p < 0.01). These results could be guidance for counsel or sand therapists for children with attention deficit disorder—ADHD.展开更多

The effect of can parameters on the mechanical behavior of TiAl alloys with different H/D ratios was analyzed in this process. The results show that, the peak stress of TiAl base alloy without canning is far higher than that with canning. Compared with the samples with the same H/D ratio, the peak stress decreases with increasing can thickness; while compared with the samples with the same can thickness, the peak stress decreases with increasing H/D ratio. The decrease of the true stress of TiAl base alloy with canning were analyzed according to the theory of plastic deformation and results of computer simulation.展开更多
