First, problems and characteristics of knowledge sharing in multi-projects of chemical engineering design are analyzed. Then based on theories of project management, process management, and knowledge management, a process-oriented knowledge-sharing platform is proposed. The platform has three characteristics: knowledge is divided into professional knowledge and project management knowledge; knowledge sharing is integrated with the project process, which makes knowledge sharing a necessary part of the project process and ensures the quantity of knowledge shared; the platform provides quantitative measurements of incentive mechanisms for knowledge providers and users which ensures the quality of knowledge shared. This knowledge-sharing platform uses two knowledge management tools, a knowledge map and a knowledge base, to support the platform.展开更多

Knowledge base is the important component for such kind of systems, but it is difficult and time-consuming to construct the knowledge base manually. Fortunately, there emerges large number of Q&A pairs in many psychological counseling websites, which can provide good source enriching the knowledge base. This paper presents the method of knowledge extraction from psychological consulting Q&A pairs of on-line psychological counseling websites, which include keywords, semantic extension and word sequence. P-XML, which is the knowledge template based on XML, is also designed to store the knowledge. The extracted knowledge has been successfully used in our non-obstructive psychologycal counseling system, called P.A.L., and the experimental results also demonstrated the feasibility and effectiveness of our approach.展开更多

Implementing knowledge management can integrate dispersed and unordered knowledge into organic and organizational knowledge system. Effective application and continuous enhancement of organizational knowledge system can from the core competence of software enterprise. For the characteristic that the software enterprise gives priority to software development, the paper uses the knowledge in the process of software development as the core （it is limited to time and energy and doesn＇ t involve the knowledge of the other departments）, and develops the research on the construction of knowledge system of software enterprise. For the knowledge system, the paper constructs and implements a knowledge management platform supporting the operation and management.展开更多

Methods: the September 2018 to June 2019 was selected as the research period and the data was recorded in the database for that period. A total of 110 patients were enrolled and diagnosed with diabetes were selected as the research objects. The basic data of the patients were recorded, and the patients were evenly divided into two groups by the database. The samples in the group were 55, and the patients were randomly divided into the control group and the experimental group by the system. Patients in the control group were given routine nursing intervention after discharge, while patients in the experimental group were given extended nursing service after discharge. The nursing quality of two groups was compared. Results: the self-management ability in the experimental group was significantly higher than that in the control group. The results were statistically significant (P < 0.05). In addition, the blood glucose level of the experimental group was well controlled. Compared with the control group, the blood glucose level of the experimental group was significantly lower than that in the control group. The difference was significant, (P < 0.05). Conclusion: the application of Wechat platform in the extended nursing service for patients with diabetes can further improve the condition of patients to a certain extent, which is of positive significance and of good applicable value for the follow-up treatment of patients.展开更多
