Relationship between physical activity and specific working memory indicators of depressive symptoms in university students

BACKGROUND The detection rate of depression among university students has been increasing in recent years,becoming one of the main psychological diseases that endangers their physical and mental health.According to statistics,self-harm and suicide,for which there is no effective intervention,are the second leading causes of death.AIM To explore the relationship between different elements and levels of physical activity and college students’depression-symptom-specific working memory indicators.METHODS Of 143 college students were analyzed using the Beck Depression Self-Rating Scale,the Physical Activity Rating Scale,and the Working Memory Task.RESULTS There was a significant difference between college students with depressive symptoms and healthy college students in completing verbal and spatial working memory(SWM)tasks correctly(all P<0.01).Physical Activity Scale-3 scores were significantly and positively correlated with the correct rate of the verbal working memory task(r=0.166)and the correct rate of the SWM task(r=0.210)(all P<0.05).There were significant differences in the correct rates of verbal and SWM tasks according to different exercise intensities(all P<0.05)and different exercise durations(all P<0.05),and no significant differences in the correct rates of verbal and SWM tasks by exercise frequency(all P>0.05).CONCLUSION An increase in physical exercise among college students,particularly medium-and high-intensity exercise and exercise of 30 min or more,can improve the correct rate of completing working memory tasks.

Research on the Development Model of University Archives Cultural Products Based on Deep Learning

The products of an archival culture in colleges and universities are the final result of the development of archival cultural resources,and the development of archival cultural effects in colleges and universities should be an important part of improving the artistic level of libraries.The existing RippleNet model doesn’t consider the influence of key nodes on recommendation results,and the recommendation accuracy is not high.Therefore,based on the RippleNet model,this paper introduces the influence of complex network nodes into the model and puts forward the Cn RippleNet model.The performance of the model is verified by experiments,which provide a theoretical basis for the promotion and recommendation of its cultural products of universarchives,solve the problem that RippleNet doesn’t consider the influence of key nodes on recommendation results,and improve the recommendation accuracy.This paper also combs the development course of archival cultural products in detail.Finally,based on the Cn-RippleNet model,the cultural effect of university archives is recommended and popularized.

Documenting the University's history in a digital era: Organizing and presenting archival resources at Lingnan University

Purpose: This paper chronicles Lingnan University(Hong Kong) Library’s experience in adopting the open source archival information system, Archon, and an institutional repository(IR) platform, Digital Commons, to create a holistic system for describing, managing and preserving the University’s historical documents.Design/Methodology/Approach: By combining the strength of Archon with Digital Commons, the Library can apply proper archival encoding practice with digital publishing capability to assemble the disparate and fragmentary Lingnan historical records into a more cohesive and well-organized historical collection facilitating wider access.Findings: Both the encoding process and digital publishing efforts have broadened access to several unique and valuable Lingnan records, providing greater search capabilities and accessibility. These initial sets of processed resources have successfully attracted attention from researchers and alumni who have strong interest in consulting the records. Together Archon and Digital Commons provide an ideal platform enabling the Library to reach out to more people who may also be interested in the records and have resulted in more donations to the Archives, further enriching the collection.Research limitations: Our initial efforts have created a solid foundation that we can use to develop a comprehensive archival collection showcasing the history of Lingnan University.However, the Library will need to develop a long-term strategy to formalize University archive policy for the ongoing systematic collection of university records and the effective management of born-digital data.Practical implications: Archival or historical records no longer need to be hidden or inaccessible due to lack of appropriate finding aids and search and retrieval systems. Archon provides an organizational and descriptive framework for the Library to process archival materials and create digital finding aids instantly in compliance with international archival standards, whereas IR software such as Digital Commons offers us a digital publishing platform to present the full-text content of these records online for worldwide access. We believe that as important as it is to collect and process a university’s records for historical preservation, it is equally important to make them easily available and accessible. By exploring the possibility of adopting new tools to manage old processes, we can add value while creating visibility for materials that were once hidden and inaccessible beyond our campus.Originality/value: As the first library in greater China to adopt Archon as well as use an IR platform, Digital Commons, to process archival materials and chronicle a university’s history, Lingnan University Library introduces a new approach that blends tools and resources of both archives and libraries to present a cohesive archival collection in a new digital era.

Universal memory based on phase-change materials:From phase-change random access memory to optoelectronic hybrid storage

The era of information explosion is coming and information need to be continuously stored and randomly accessed over long-term periods,which constitute an insurmountable challenge for existing data centers.At present,computing devices use the von Neumann architecture with separate computing and memory units,which exposes the shortcomings of“memory bottleneck”.Nonvolatile memristor can realize data storage and in-memory computing at the same time and promises to overcome this bottleneck.Phase-change random access memory(PCRAM)is called one of the best solutions for next generation non-volatile memory.Due to its high speed,good data retention,high density,low power consumption,PCRAM has the broad commercial prospects in the in-memory computing application.In this review,the research progress of phase-change materials and device structures for PCRAM,as well as the most critical performances for a universal memory,such as speed,capacity,and power consumption,are reviewed.By comparing the advantages and disadvantages of phase-change optical disk and PCRAM,a new concept of optoelectronic hybrid storage based on phase-change material is proposed.Furthermore,its feasibility to replace existing memory technologies as a universal memory is also discussed as well.
