Analysis and Study on Square Dance in the City
Zejun Zhang,Xiaomei lv 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.4
In recent years, with the increase of stress at work, more and more people begin to pay close attention to the public fitness, in order to improve the quality of the individual body and psychological quality. Square dancing is a sport that is suitable for all ages, with fitness, healthy heart, strong and handsome brain as a whole, which is the best fitness way to communicate and is loved by people. The author inquire into the status of square dance of Lanzhou city residents, analysis square dance exercise participants the characteristics of its own characteristics and square dance, draw a few Suggestions to promote the development of Lanzhou city square dance. The organizers should be scientific and standardized management of venues, highlight the cultural characteristics of square dance and strengthen the training and guidance, in order to improve the Lanzhou city square dance movement to develop quickly and well.

The aim of this study was to explore the eff ects of inoculating with diff erent fungi on the structural characteristics of soil fungal communities and the nutrient absorption of blueberry plants. The fungi DSE ( Phialocephala fortinii ), SS ( Penicillium pinophilum ), ZB ( Cladosporium cladosporioides ), QMK ( Chaetomium globosum ), and LZ ( Schizophyllum commune ) were selected for this study. The soil fungal diversity and community structure in the blueberry rhizosphere were compared after inoculation with these diff erent mycorrhizal fungi. The fungal diversity in the blueberry rhizosphere soil was signifi cantly higher after inoculation with DSE, QMK, and ZB than after inoculation with SS and LZ. The dominant class, order, family, and genus of soil fungi were Eurotiomycetes (25.49–36.91%), Eurotiales (24.78–35.00%), Aspergillaceae (24.47–34.74%), and Penicllium (24.34–34.63%), respectively. Among all the fungal treatments, DSE led to the highest abundance of dominant classes, orders, families, and genera. Inoculation with SS, LZ, and DSE increased the contents of nitrogen, phosphorus, and potassium in blueberry plants. The uptake of nitrogen, phosphorus, and potassium were highest in DSE-inoculated plants. The nitrogen content was signifi cantly higher in ZB-inoculated plants than in the control. A TOPSIS analysis showed that among the fi ve fungi, DSE was the best strain to improve the diversity of the blueberry rhizosphere fungal community and promote nutrient uptake by blueberry plants, followed by LZ and ZB. These fi ndings provide scientifi c data for the develop ment and utilization of soil microbial resources, and provide useful information for improving the cultivation and production of blueberries.

Purpose Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy. Materials and Methods Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤ T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate. Results Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladder-sparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladder-sparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory. Conclusion After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory bladder-sparing rate, prognosis, and bladder function. The CR rate reflected the real NAC efficacy for MIBC. This therapy is worth verifying through multicenter research.

This paper presents an efficient algorithm that segments the synthetic aperture radar (SAR) image into several homogeneous regions by combining edge- and region-based information. A multi-direction ratio edge detector is used to capture the locally directional variation information of a SAR image and construct the ratio edge strength map (RESM) of the SAR image. Watershed transformation is performed on the thresholded RESM to obtain an over-segmentation result. An efficient hierarchical region merging procedure based on the region adjacency graph representation of the image regions is proposed. A novel dissimilarity measurement between the two adjacent regions is derived from the multiplicative noise speckle model of the multi-look SAR image. Experimental results and the performance evaluation show that the proposed method outperforms two widely used SAR image segmentation approaches.
