Exploration on the Long-term Education System of Software Engineering

It is a challenge to cultivate senior and comprehensive talents in software engineering.To promote the quality of software engineering education,this paper proposes a new education model of long-term education system and combines Bachelor-Master degree program by mirroring the experience of higher engineering education in the world and integrating with the current situation of universities and industries in China.The proposed model joins the higher degree education with vocational education by carrying out the interdisciplinary and university-enterprise joint education.The demonstration shows that this education model has its necessity and feasibility in China higher education,and provides a reference to improve the education quality for the higher engineering education in China.

Sucrose Secreted by the Engineered Cyanobacterium and Its Fermentability

The unicellular cyanobacterium, Synechococcus elongatus PCC 7942(Syn7942), synthesizes sucrose as the only compatible solute under salt stress. A series of engineered Syn7942 strains for sucrose production were constructed. The overexpression of the native sps(encoding a natively fused protein of sucrose phosphate synthase SPS and sucrose phosphate phosphatase SPP) in Syn7942 wild type caused a 93% improvement of sucrose productivity. The strain FL130 co-overexpressing sps and csc B(encoding a sucrose transporter) exhibited a 74% higher extracellular sucrose production than that overexpressing csc B only. Both results showed the significant improvement of sucrose productivity by the double functional protein SPS-SPP. Afterwards, FL130 was cultivated under a modified condition, and the cell-free culture medium containing 1.5 g L-1 sucrose was pre-treated with an acid hydrolysis technique. Cultivated with the neutralized hydrolysates as the starting media, two widely used microorganisms, Escherichia coli and Saccharomyces cerevisiae, showed a comparable growth with that in the control media supplemented with glucose. These results clearly demonstrated that the cell-free culture of sucrose-secreting cyanobacteria can be applied as starting media in microbial cultivation.

University culture, project culture and enterprise culture jointly build the training road of the excellent engineers

The ＂Education and training plan of excellence engineers＂ is the base to comprehensively improve the training quality of the engineering talents, and is the power and guarantee of our country to march towards the great power of the engineering education fi＇om the engineering educational power. In the training process, not only it is required to complete the training and improvement of the theoretical knowledge, the practical abilities and the engineering qualities in the colleges, but it also needs the active participation and the close cooperation of the enterprises. Therefore, the students will have the influence of the effects and edification from the university culture, the project culture and the enterprise culture, and will feel the power and benefits a variety of cultures bring about by interleaving. This paper expounds the important position and the function of the university culture, the project culture, and the enterprise culture in the personal training, and elucidates that the complete fusion of the three is the social ideal and support to complete the task of cultivating the outstanding engineers.

Current Status and Research Trends of Panax Between 1900—2019:A Bibliometric Analysis

Objective:To investigate the current status and further dtevelopment of Panax genus and6 important individual species including P.notoginseng,P.quinquefolium,P.vietnamensis,P.japonicus,P.stipuleanatus and P.zingiberensis.Methods:The bibliometric analysis was based on the Web of Science core database platform from Thomson Reuters.Totally,7,574 records of scientific research of Panax species published from 1900—2019 were analyzed.The statistical and visualization analysis was performed by CiteSpace and HistCite software.Results:The academic research of Panax species increase promptly.Plant science is the main research field while research and experimental medicine and agricultural engineering will be the further development tendency.Particularly,the discrimination research of P.notoginseng will be the research tendency among Panax species,especially diversity research.In addition,P.vietnamensis deserves more attention in the genus Panax.Conclusion:This research provides a reference for further research of the genus and individual species.
