The widespread use of mobile Internet and the popularization of intelligent electronic devices make it difficult for students to focus their attention completely on the classroom. In view of the above two points, this paper redesigns the computer network classroom by using the Fanya SPOC （Small Private Online Course） teaching platform and adopting the teaching mode of flipped classroom to stimulate students＇ interest in learning and improve their learning effect.展开更多

Methods Eighty-two cases of lumbar disc herniation, from February 1996 to May 1999, were retrospectively studied. All patients were treated with simple fenestrated discectomy. The average follow-up time was 8 years and 7 months （from 7 years tolO years and 3months）. There were 13, 38 and 31 cases at 13 - L4, L4 - L5 and L5 - S1 level, respectively. Results The average scales before operation were as following ： Japanes Orthopaedics Association （ JOA ） scale 6. 5 （ 5 - 9 ） , visual analysis scale （ VAS） of low back pain4.8 （0-8）. and VAS of sciatica 7.2 （4-10）. At the final follow-up, the above parameters were 13.2 （ 10 - 14 ）, 1.8 （0 - 10） and 1.2 （0 - 7）, respectively. The average increase ratio of JOA scale was 78. 8%. The average disc-vertebra height ratio （ Mochida method） was 80.2%. At the final follow-up, 7 cases reoccurred disc herniation. The final clinical satisfaction rate was 80% （ modified Macnab method ）. Conclusion With appropriate surgical indications, the successfid long-term outcomes could be expected with fenestrated discectomy. Discectomy improves sciatica to a greater extent than low back pain. The occurrence of low back pain is related to intervertebral disc height, segment stability, disc degeneration, and lumbar muscle disability.展开更多

The subject can be an individual, a group, or an institution, and can be a nation depending on the nature of the relevant information. Most web data are composed of a title, an author, and contents. A paper which is under the academic information category has metadata including a title, an author, keyword, abstract, data about publication, place of publication, ISSN, and the like. A patent has metadata including the title, an applicant, an inventor, an attorney, IPC, number of application, and claims of the invention. Most web-based academic information services enable users to search the information by processing the meta-information. An important element is to search information by using the author field which corresponds to a personal name. This study suggests a method of efficient indexing and using the adjacent operation result ranking algorithm to which phrase search-based boosting elements are applied, and thus improving the accuracy of the search results of author name. This method can be effectively applied to providing accurate search results in the academic information services.展开更多

Art decorative design reflects the characteristics of the environment, history and culture of a city and a state of the spirit of the times. Modem art deco design should not only have its own style, but also be more perfectly reflect the cultural connotation of specific urban environment, and to create a pleasant living environment for human being. Aesthetic concepts of decorating space environment are inseparable from the people＇s view of decoration. Analyzing from the sensory effects and psychological effects of decorative environment, the paper points out the way for environmental decoration development, and provide ideas for future creative decoration.展开更多
