With the popularity of 5G and the rapid development of mobile terminals,an endless stream of short video software exists.Browsing short-form mobile video in fragmented time has become the mainstream of user’s life.Hence,designing an efficient short video recommendation method has become important for major network platforms to attract users and satisfy their requirements.Nevertheless,the explosive growth of data leads to the low efficiency of the algorithm,which fails to distill users’points of interest on one hand effectively.On the other hand,integrating user preferences and the content of items urgently intensify the requirements for platform recommendation.In this paper,we propose a collaborative filtering algorithm,integrating time context information and user context,which pours attention into expanding and discovering user interest.In the first place,we introduce the temporal context information into the typical collaborative filtering algorithm,and leverage the popularity penalty function to weight the similarity between recommended short videos and the historical short videos.There remains one more point.We also introduce the user situation into the traditional collaborative filtering recommendation algorithm,considering the context information of users in the generation recommendation stage,and weight the recommended short-formvideos of candidates.At last,a diverse approach is used to generate a Top-K recommendation list for users.And through a case study,we illustrate the accuracy and diversity of the proposed method. 展开更多

Objective:To study the application effect of short video combined with BOPPPS teaching mode in clinical anesthesia practice.Method:48 students assigned to clinical anesthesia in digestive endoscopy of Shanxi Bethune Hospital from July 1,2022 to April 1,2023 were selected as research objects.They were randomly divided into the control group(PowerPoint presentation teaching group)and the observation group(short video combined with BOPPPS teaching group),with 24 students in each group.After the internship,the students’theoretical and technical scores were tested,the effects of the two teaching modes were compared,and the students’satisfaction was investigated.Results:The test scores of students in the observation group were significantly better than those in the control group(P<0.05).The short video combined with BOPPPS teaching mode can significantly improve students’learning interest,operation skills,and memory(P<0.05).The students’satisfaction in the observation group was higher than that in the control group(P<0.05).Conclusion:In clinical practice,the application of short video combined with BOPPPS teaching mode has achieved great effect,which is worth further promotion and research. 展开更多

In the era of convergence media,short video clips,as a new form of mass communication,provide a new driving force for the upgrading and transformation of traditional media.Short videos are a product of the rapid development of visual culture in the Internet Plus era,which focuses on image communication and perceptual experience.In the all-media environment,the audience’s perception ability has been extended as the news scene offers an intense sense of immersion.Short-form videos provide viewers with fresh narrative modes and new perspectives.In particular,H5,VR/AR,and other technologies have changed the short video pattern with a new expression of audio-visual language,thus greatly increasing the communication power and attraction.The growing popularity of short videos,known as the New King of All Media,results from the combination of technology and culture,such as big data,5G,VR/AR,AI,block chain,and hologram.How to keep the competitiveness of short videos with an upsurge in content consumption in the era of 5G is a question we should ponder. 展开更多

Since the era of tourism gaze,in the process of shaping cultural tourism images,film and television works have influenced the landscape formation and cultural transmission of a place through the lens and the attention of the audiences.With the evolution of media and the development of technology,the short videos on rural cultural tourism in China in the digital era go beyond gazing but directly generate the landscape and culture of a place in the real-time multi-directional interaction.With the mobilization mode of dual sensory integration,the short videos on rural cultural tourism in China become geographic media attracting users to participate in emotional communication and tourism practice beyond the objective rational orientation.They attract users to integrate re-localization experiences in real world from the media localization image presentation,and trigger embodied practice from virtual sensory presence.By the ubiquitous interactive nature of digital media and reality,the short videos demonstrate the constructive and generative power of symbolic reality for reality.With the help of technology,the short videos spread local culture all over the world via pre-storing the physical tourism in the callable space and topological time.Through the free transduction of relational logical networks,the short videos make the transition from Plato’s cave,the mimicry environment into the real world,to awaken perception of Chinese solar terms from the time-less sequence,and construct tourism and culture,online,and offline. 展开更多

Video accelerator is developed for better user experience in video sharing websites such as YouTube.PPLive video accelerator (PPVA),which has the largest number of users in China,is based on peer-to-peer (P2P) system.The number of videos and peers in PPVA is by orders of magnitude many times larger than which in traditional P2P video on demand (VoD) system.As a result,even though the resource is sufficient,due to unfairness assignment,the quality of service can hardly satisfy all users.In this paper,we concentrate on the assignment of the fundamental resources in PPVA:storage and bandwidth.The problem of storage assignment is formulated as a nonlinear program (NLP) regarding the number of request as a random variable.The results show that the influence of the variance of requests is not negligible and proportional approach is appropriate only when the mean is much larger than the variance.The criteria about how to locate videos to appropriate peers are also presented,taking into account constrains such as the utilization of total bandwidth,the probability of bandwidth competition and the fairness between videos.Furthermore,the heuristic algorithms of allocating upload bandwidth in centralized and distributed fashion are proposed and evaluated against a widely used strategy (equal allocation) with respect to the balance among videos.Simulation results demonstrate that both algorithms can lead to significant performance improvement. 展开更多
