RESUMO

As the second lifeline of human body, the abnormal development of its morphological structure has a great impact on people's physical and mental health. Due to bad living habits and learning pressure, the morphological and structural development of spine in adolescents and children is abnormal to a certain extent, which can be improved by sports intervention. Therefore, this article puts forward the research on the influence of Wushu on the spinal morphological structure based on the optimization algorithm and integrates the optimization ant colony algorithm on the basis of the traditional spinal CT image segmentation method. The experimental results show that the improved CT image segmentation method based on the optimized ant colony algorithm can solve the sensitive problem of the number of clusters, improve the segmentation efficiency and quality, and provide more accurate data for the subsequent comparative experiments. At the same time, the comparative test results show that Wuqinxi Wushu can better improve the abnormal dry tilt angle, abnormal kyphosis angle, and body balance angle of teenagers, improve the activity of teenagers' spine, and help teenagers enhance the overall health of spine.

RESUMO

This paper addresses the problem of detecting coherent motions in crowd scenes and presents its two applications in crowd scene understanding: semantic region detection and recurrent activity mining. It processes input motion fields (e.g., optical flow fields) and produces a coherent motion field named thermal energy field. The thermal energy field is able to capture both motion correlation among particles and the motion trends of individual particles, which are helpful to discover coherency among them. We further introduce a two-step clustering process to construct stable semantic regions from the extracted time-varying coherent motions. These semantic regions can be used to recognize pre-defined activities in crowd scenes. Finally, we introduce a cluster-and-merge process, which automatically discovers recurrent activities in crowd scenes by clustering and merging the extracted coherent motions. Experiments on various videos demonstrate the effectiveness of our approach.

RESUMO

Objective To evaluate the effect of shielding at the outside of radiation field by measuring the dose absorbed by the tissue outside the field in radiation therapy.Methods The dose absorbed by the tissue at 1cm offset the field was measured ofter setting radiation field and dose.The dose was measured again with shielding at the outside of radiation field in same field size and with the same prescription dose for comparison.Results The doses with or without shielding had distinct differences(P

RESUMO

AIM: In order to explore the mechanism of the GC - like effect of Tsiao Shaihutang (TSS), the down - regulation of glucocorticoid receptor and mRNA by TSS were studied. METHODS: GR sites were determined by receptor radio ligand binding assay method. At the same time, GR mRNA level was determined by quantitative reverse- transcriptive polymerase chain reaction (RT- PCR) method. RESULTS: (1) GR sites and GR mRNA level were down - regulated significantly after GC, TSS (P < 0.01 ) treatment . (2) GR sites and GR mRNA level in GC plus TSS group were obviously higher than those in GC group (P < 0.01 ). CONCLUSIONS: These data suggested that TSS can significantly down- regulate GR and GR mRNA level.
