It is not only related to our country's economic development, but also has a decisive impact on our country's tax revenue directly. Under the background of the current era of rapid economic growth, the reality of cigarette brand cultivation will inevitably affect the development of our country's tobacco industry. The newly arisen live broadcast industry has injected new vitality into the cultivation of cigarette brands. By means of live broadcast, tobacco sales enterprises have not only greatly improved the efficiency of cigarette brand cultivation, but also provided more available methods and means for the cultivation of cigarette brands. This paper mainly expounds the feasibility and practical application of enterprise live broadcasting in the cultivation and application of cigarette brands.展开更多

Aiming at the disadvantage that the current Peer-to-Peer (P2P) is hard to manage and control, this paper presents a Session Initial Protocol (SIP)-based P2P network of three-level architecture. SIP middleware is introduced to the middle level of the three-layer architecture. By the connection function of the SIP signaling, the P2P transmission on media-level can be controlled. Using SIP’s register and authentication function, the manage layer can manage the whole P2P network. Based on the aforementioned architecture, this paper investigates the grouping strategy on a live broadcast application in P2P network. Combined with the function of SIP register, the paper works on several grouping strategies, sets up models to manage users by grouping them, presents a weight-based K-means IP address grouping algorithm, and realizes it. The experiment shows that the grouping strategy presented in this paper can solve the problem of group sharing of network resource, and can realize the efficient-sharing, reasonable-distributing of network resource.展开更多

Methods: a total of 60 nursing students were enrolled in this study from February to October 2019. Randomly divided into groups, 30 cases in each group. The control group chose conventional mode to carry out rain classroom live broadcast online teaching, while the observation group chose rain classroom live broadcast combined with flipped interactive teaching mode to compare the application effects of different teaching modes and students' evaluation of the teaching mode. Results: the scores of the two groups were higher in the observation group than in the control group (P < 0.05). There was a significant difference in students' satisfaction with the teaching mode between the two groups, and the observation group was relatively higher (P < 0.05). There were significant differences between the two groups in single video learning duration, clicks and number of effective bullet screen in class, and the mean values of observation group were higher than those of control group (P < 0.05). Conclusion: in online teaching of psychiatric nursing, the flipped interactive teaching mode of rain classroom live broadcast can obtain ideal application effect. On the one hand, it can enhance students' participation in learning and strengthen teaching quality. Students give high evaluation to the teaching mode, which has the value of promotion and application.展开更多

The sudden change has also ushered in new challenges for the education field including colleges and universities. At the same time, there is also a c ontradiction between demand and supply. In order to further solve the contradiction between supply and demand, we must adhere to the principles of "based on demand, student-oriented", "two-way force, adhere to the overall integration of elements" and other principles, effectively promote the online course to achieve seamless convergence, and then achieve "1 + 1 >2", and improve the high-efficiency learning effect of online courses.展开更多
