The surreal space of digital technology development has created an unprecedented utopian mythological world.The virtual reality research started in the 1960s has gradually become a reality with the support of hardware technology.The media mode of observing the world by simulating human eyes with cameras is being replaced by computer simulation technology.The metaverse global vision based on virtual space and sense of time obscures the traditional perspective,and a novel progressive aesthetic category gradual y emerges.Starting with the aesthetic experience of myth brought by digital technology,this paper reviews the history of myth and analyzes the mental image of myth and religion to push the origin of life to a more profound realm.The contemporary“myth”following technological development changes the situation of human cognition of the world,separates the myth from the historical frame and relates it to the contemporary ongoing. 展开更多

The deep integration of digital technology and the real economy is a vital engine for boosting high-quality growth of the real economy.As a result,it is necessary to investigate the effects of this integration on the real economy.This paper develops a two-sector model that incorporates the production sector and the technology research and development sector,taking into account both the factor attribute and the technical attribute of digital technology.Digital capital,general capital,skilled labor,and unskilled labor are considered as intermediate inputs in the model.Furthermore,this paper examines the effects of two integration modes,i.e.,factor-based integration and technology-based integration,on the development of the real economy and the biased technical change from a theoretical perspective.Empirical tests are conducted to support the analysis.The findings indicate that both factor-based integration and technology-based integration contribute positively to the development of the real economy,although technology-based integration exhibits diminishing marginal effects.Heterogeneity analysis reveals that factor-based integration plays a more significant role in promoting the development of the real economy in regions with geographical advantages,low levels of human resources,high marketization levels,or low market segmentation.On the other hand,technology-based integration assumes a greater role in facilitating the development of the real economy in regions with geographical disadvantages,low costs on human resources,low marketization levels,or high market segmentation.Further analysis demonstrates that the integration of digital technology and the real economy leads to digital capital-biased technical change and skilled labor-biased technical change.Therefore,it is imperative for the public sector to encourage the expansion of both factor-based integration and technology-based integration in the real economy.Additionally,it is also important to develop a reasonable industry layout plan and enhance the skill level of workers to address the rising demand for relevant factors resulting from changes in the biased technical change. 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

Threshold decision is an important function of nuclear instrument control system based on physical parameters threshold decision. Because the conventional decision methods lack correlation with time and conditions, by analyzing the existing methods, some optimized methods are adopted. Considering safety, those methods are improved in data processing algorithms, floating threshold with multiple values, association with specific working condition, etc. These measures im- prove the nuclear instrument control system in fault tolerance and fault diagnosis, especially, the shutdown number of nucle- ar power plant decreases. 展开更多
