This research constructs the concept model and mechanism of knowledge collaboration in software enterprises from the perspective of open innovation, helps software enterprises in China to reduce the cost of knowledge innovation, and achieve win-win results and achieve the synergy effect of "1 +1>2". [Methods/Process] Based on the existing theories, the paper constructs a conceptual model of knowledge collaboration and related mechanism for software enterprises. [Results/Conclusions] We discuss the process of knowledge sharing, identification, transfer, application and innovation between software enterprises and external stakeholders to promote the optimal use of knowledge resources. We put forward the knowledge collaboration mechanism of software enterprises from the perspective of open innovation, including heterogeneous coordination mechanism, trust and communication mechanism, benefit distribution mechanism and property right protection mechanism, in order to enrich the research in the field of knowledge collaboration and provide guidance for software enterprises.

[Purpose / Significance] The development of blockchain technology has brought new opportunities to the construction of scientific research integrity. Utilizing the characteristics of blockchain that cannot be tampered with and forged, it can effectively solve problems such as the credibility of scientific research results and the identification of authenticity. The ordered pattern and fixed format of the data on the chain also provide solutions for unifying the uneven data of various platforms. [Method / Process] Based on the rigorous hierarchical structure of the blockchain, this paper designs an architectural model that conforms to the characteristics of a scientific research integrity system. It applies an open source technology platform for data classification storage and on-chain operations. Based on the library institutional repository and graduates' paper platform, this paper analyzes the process by which scientific misconduct is recorded and tracked. [Results / Conclusions] The characteristics of distributed storage of the blockchain will make the scientific research results in the library management platform open and transparent, while protecting the copyright of scientific research. It also allows academic misconduct such as plagiarism and falsified data to appear, thereby effectively improving scientific research proactive awareness of integrity and providing theoretical and practical help to scientific institutions and researchers.

[Methods/Procedures] The authors first surveyed the current status of gaming services for the elderly in public libraries at home and abroad by literature review and visiting library websites. Then semi-structured interviews were conducted with 14 elderly readers to investigate and analyze their demand for library gaming services. [Results/Conclusions] Based on the research results and drawing on the successful experience of providing gaming services for senior users of international public libraries, this paper puts forward rational suggestions for the development of gaming services for the elderly in public libraries in China from five aspects: service concept, service resources, service form, service mechanism, and service management.

[Purpose/Significance] Reading promotion is an important task for university libraries. Studying the reading promotion work in Arts university libraries, as an important part of university libraries, can provide some references for other university libraries to promote reading among the public. [Method/Process] Taking the reading promotion work of Tianjin Conservatory of Music Library as the research object, and through the analysis of the subject and object of the reading promotion, readers and ways of promotion, this paper explores the existing problems in the reading promotion work of art university libraries and puts forward countermeasures and suggestions. [Results/Conclusions] Art university libraries should give full play to their functional advantages, improve their political standing, carry out work around the overall development of the university, and strengthen the top-level design of reading promotion. In the selection of reading materials, we should deepen the investigation and combine readers' professional background and reading preferences to provide accurate services. In terms of promotion methods, this paper highlights the professional characteristics of art colleges and universities, emphasizes the aesthetic value of art, and creates promotion brands. In the development of activities, we need to deepen cooperation and establish a long-term mechanism.
