文摘This study investigates how to pedagogically integrate ideological education with competency development in the Intercultural Communication course,a challenge arising from China’s dual reform contexts of the New Liberal Arts initiative and the national curriculum ideology policy.As global interactions intensify,cultivating foreign language professionals who possess both firm cultural confidence and sophisticated intercultural competence have become a critical educational imperative.This exploratory study investigates how a three-dimensional“Value-Knowledge-Competency”framework can guide the redesign of course content,task design,and assessment to achieve organic fusion.Drawing on qualitative data from a case study,it analyzes specific implementation pathways,synthesizes teacher and student feedback,and discusses the resultant challenges and broader implications for foreign language curriculum reform.The findings suggest that such an integrated approach can effectively synergize value guidance with skill cultivation,though its success hinges on overcoming issues related to pedagogical naturalness,resource allocation,and standardized evaluation.

文摘Intelligent refractory materials represent a new generation of high-temperature functional materials that significantly enhance the service performance of traditional refractories in extreme environments through integrated sensing,response,and adaptive mechanisms.A comprehensive overview of intelligent refractory materials was provided,focusing on their classification,preparation techniques,and industrial applications.Firstly,the categories and design principles of intelligent refractory materials are introduced,including self-healing,self-regulating,and self-diagnosing types,which enhance durability and performance under extreme conditions.Subsequently,advanced preparation technologies are discussed,such as 3D printing for complex geometries,nanocomposite engineering for improved mechanical and thermal properties,gradient design for optimized thermal stress resistance and information technology including machine learning,health monitoring,digital twin.Finally,the industrial applications of these materials are highlighted,particularly in steel metallurgy,building materials industry,and energy.It aims to bridge the gap between research advancements and practical implementation,offering insights into future trends in intelligent refractory material development.
文摘The occurrence of difficult arteriovenous fistulas makes the use of vascular access in hemodialysis patients face great challenges.With the widespread application of point-of-care ultrasound,POCUS technology,it provides a new solution for clinical practice.This article reviews the principle,basic process,application status,current clinical challenges and development direction of difficult arteriovenous fistulas cannulation guided by POCUS technology,in order to provide reference for the standardized clinical application and future research direction of this technology.
文摘Before joining the Beijing Dragon Shadow Puppetry Art Theatre,this group of young people rarely had the chance to meet people like themselves,lacked friends,faced obstacles at work,and felt alienated from society.Now,they have gained appreciation,recognition,confidence,friendships,and love.
文摘Lin Shuran and her husband Fang Chuxiang are exceptional artists who are often mentioned together when talking about contemporary Lingnan art.Compared to her husband’s fame in the field of flower-andbird painting,Lin shows unique artistic sensitivity as a female inheritor of the Lingnan School and quietly preserves the cultural lineage of Lingnan painting.

文摘Rare earth(RE)Y-type zeolite was synthesized in situ by acidic co-hydrolysis route and hydrothermal method.The key process parameters were optimized based on the RE utilization rate.The effect of inducing a rotating packed bed(RPB)in premixing and crystallization on crystallinity and RE utilization rate was further investigated.The results indicate that lanthanide(La)cations are successfully introduced into the sodalite cage of Y-type zeolite.The optimized conditions are that the molar ratio of Si/La is 150,premixing for 5 h,crystallization at 90℃ for 18 h,and calcination at 550℃ for 3.5 h.At this stage,the RE utilization rate reaches 74.5%.Compared with the conventional stirred tank reactor(STR),RPB can effectively shorten the premixing time and crystallization time by 4.3 h and 6 h,improve the crystallinity by 23%and RE utilization rate by 7.5%.The RE utilization rate is more than 80%by RPB,surpassing the effectiveness of using the one-exchange one-calcination process in the traditional liquid ion exchange process.It is expected to provide a reference for the in-situ efficient and green synthesis of RE zeolite.
文摘Healthy behavior has long been linked to mental health outcomes.However,the role of artificial intelligence(AI)literacy in shaping healthy behaviors and its potential impact on mental health remains underexplored.This paper presents a scoping review offering a novel perspective on the intersection of healthy behaviors,mental health,and AI literacy.By examining how individuals’understanding of AI influences their choices regarding nutrition and their susceptibility to mental health issues,the current study explores emerging trends in health behavior decision-making.This emphasizes the need for integrating AI literacy into mental health and health behaviors education,as well as the development of AI-driven tools to support healthier behavior choices.It highlights that individuals with low AI literacy may misinterpret or overly depend on AI guidance,resulting in maladaptive health choices,while those with high AI literacy may be more likely to engage reflectively and sustain positive behaviors.The paper outlines the importance of inclusive education,user-centered design,and community-based support systems to enhance AI literacy for digitally marginalized groups.AI literacy may be positioned as a key determinant of health equity,better allowing for interdisciplinary strategies that empower individuals to make informed,autonomous decisions that promote both physical and mental health.
