Exploration and Practice of the"One-Student-Two-Tutors"Community through Integrating"1+3 Teaching Resources"into Undergraduate Experimental Teaching

This study closely follows the spirit of the first class undergraduate education action plan(2021-2025)of University of Shanghai for Science and Technology,combines with the national first-class undergraduate professional training plan of mechanical design and manufacturing and automation,and carries out the exploration and practice of"1+3 teaching resources"integrating into the"One-Student-Two-Tutors"community of undergraduate experimental teaching.On the basis of creating a good learning environment and creating an excellent learning platform,this paper studies the undergraduate experimental teaching of the trinity of"theoretical courses+experimental courses+innovation and entrepreneurship activities,discipline competitions,and scientific research project activities".This study has a certain reference value for colleges and universities to cultivate outstanding engineering talents with happy learning attitude,scientific research interest,practical ability and innovative ability.

Application and Practice of Knowledge Graph in Experimental Teaching in Colleges and Universities

With the reform of experimental teaching in colleges and universities,the teaching mode of"experimental students as the main body,experimental teachers as the guide"needs to constantly explore new experimental teaching methods.In this paper,knowledge graph is integrated into the experiment of mechanical principle to guide undergraduates to use knowledge graph to analyze and summarize independently in experimental teaching activities,aiming at cultivating undergraduates interest in learning and innovative thinking,so as to improve the quality of experimental teaching.This study has a certain reference significance for experimental teaching in colleges and universities.

Exploring the relationship-oriented spaces of social networks and depressive symptoms among older adults

The Republic of Korea has the highest suicide rate of older population among OECD countries,and depression is the prevailing factor.While it is well-known that the urban physical environment affects mental health,research on the physical characteristics of spaces remains limited.This study aims to explore relationship-oriented space characteristics that can form social networks and reduce depressive symptoms in older adults.After analyzing the differences in social interaction spaces between high-density and low-density areas for older adults in Seoul,we identified social interaction spaces(parks and traditional markets)that are frequently used based on on-site interview results.Two areas were selected for the questionnaire surveys.The main findings revealed that older adults living in areas with diverse spatial planning and close physical relationships between parks and traditional markets,convenient pedestrian environments,and lower population density of older adults had better social networks and lower depressive symptoms.More significantly,the physical characteristics of parks and traditional markets(convenient accessibility,maximized visibility,connectivity,and territoriality)significantly facilitate social interactions.Those engaging in social interactions within these spaces exhibited significantly better social networks and lower depressive symptoms.These findings underscore the importance of considering relationship-oriented space characteristics in spatial and urban planning.

Design Methodology of a Passive Vibration Isolation System for an Optical System With Sensitive Line-of-Sight

The performance of an optical system with sensitive line-of-sight(LOS)is influenced by rotational vibration.In view of this,a design methodology is proposed for a passive vibration isolation system in an optical system with sensitive LOS.Rotational vibration is attributed to two sources:transmitted from the mounting base and generated by modal coupling.Therefore,the elimination of the rotational vibration caused by coupling becomes an important part of the design of the isolation system.Additionally,the decoupling conditions of the system can be obtained.When the system is totally decoupled,the vibration on each degree of freedom(DOF)can be analyzed independently.Therefore,the stiffness and damping coefficient on each DOF could be obtained by limiting the vibration transmissibility,in accordance to actual requirements.The design of a vibration isolation system must be restricted by the size and shape of the payload and the installation space,and the layout constrains are thus also discussed.
