6Research on disaster and emergency medicine development in China and abroad显示文摘This paper first explores the development and direction of disaster and emergency medicine in China and abroad from the perspective of international environment and history background, analyses four elements of disaster and emergency medicine, including subject content, professionals, education practice and technical innovation, clarifies the interdependency between disaster medicine and emergency medicine, and reveals the developing rules of disaster medicine and emergency medicine. It also provides suggestions for China's development of disaster medicine and emergency medicine.ZHENG Jingchen PENG Bibo 2020中国研究型医院2020,7,5:0
7An Improved Frag-Shells Algorithm for Data Cube Construction Based on Irrelevance of Data Dispersion显示文摘On-Line Analytical Processing (OLAP) is based on pre-computation of data cubes, which greatly reduces the response time and improves the performance of OLAP. Frag-Shells algorithm is a common method of precomputation.However, it relies too much on the data dispersion that it performs poorly, when confronts large amount of highly disperse data. As the amount of data grows fast nowadays, the efficiency of data cube construction is increasingly becoming a significant bottleneck. In addition, with the popularity of cloud computing and big data, MapReduce framework proposed by Google is playing an increasingly prominent role in parallel processing. It is an intuitive idea that MapReduce framework can be used to enhance the efficiency of parallel data cube construction. In this paper, by improving the Frag-Shells algorithm based on the irrelevance of data dispersion, and taking advantages of the high parallelism of MapReduce framework, we propose an improved Frag-Shells algorithm based on MapReduce framework. The simulation results prove that the proposed algorithm greatly enhances the efficiency of cube construction.Dong Li Zhipeng Gao Xuesong Qiu Ran He Yuwen Hao Jingchen Zheng 2015国际计算机前沿大会会议论文集2015,,1:0
8Oviposition Regularity of Hybrid Silkworm Stock Moth of Liangguang No. 2显示文摘To cure pebrine using dry- hot air treatment of silkworm eggs,and control egg age within 12 hours,oviposition regularity of hybrid silkworm stock moth of Liangguang No. 2—current production variety in Guangdong Province was investigated. The experiment showed that most hybrid stock female moths of Liangguang No. 2 at 25- 28℃ oviposited in the first 5 hours,and egg production declined sharply after 5 hours. 7·Xiang × Fu·9 achieved the oviposition peak within 1 hour after casting the moth,the oviposition amount within 5 hours accounted for 92. 94% of the total oviposition amount of female moth,that within 9 hours accounted for96. 47%. Fu·9 × 7·Xiang achieved the oviposition peak within 2- 4 hours after casting the moth,the oviposition amount within 5 hours accounted for 85. 21%of the total oviposition amount of female moth,that within 9 hours accounted for 92. 78%. Oviposition regularity of the hybrid silkworm stock moth of Liangguang No. 2 meets the need of dry-hot air treatment of silkworm pebrine-control egg age within 12 hours.Zhong Suyuan Qiu Guoxiang Wang Xianyan Hu Zhiming Zhang Guiling Li Zheng Wen Ziwei Guo Dingguo Zhang Huacheng Sun Jingchen 2015Animal Husbandry and Feed Science2015,7,2:0
