    The current exploration of data element market construction mainly focuses on the construction of data trading venues, while the streaming data market refers to the market in which data suppliers continuously and quickly supply specific data to data users.Streaming data is not suitable for transactions in the data trading venues, so the over-the-counter trading model of streaming data needs to be explored.After studying the current operation status of the streaming data market, it was pointed out that market disorder and insufficient regulatory tools were the main problems, and a data pipeline model for the over-the-counter streaming data market was proposed, including pipeline circulation elements (data pipeline, data factory, data supply chain), market regulation elements (data meter, quality sampling device, compliance auditing device), etc.The technical feasibility of the data pipeline model was demonstrated, and it provided theoretical and technical support for the construction, regulation and supervision of the over-the-counter data market.

    Data asset valuation is the foundation of modern data asset management, operation, and data circulation.Based on the theory of the data full lifecycle, starting from first principles, single data asset table was evaluated by assessing their cost, data management, and data application value.Using technologies such as data warehousing and graph algorithms, the cost value of a single data asset table was accurately calculated by using a layer-by-layer allocation method and inheriting the lineage path.Then, the non-economic factor weight of data asset was obtained by using the analytic hierarchy process, and the value of data asset was obtained through a ladder evaluation.Finally, verifies the rationality and feasibility of the new method was verified through an example.

    The metaverse has been discussed in fields such as medicine, manufacturing, finance, education, and public services, but the application scenarios based on virtual reality have not truly achieved the ＆quot;real-virtual-real＆quot; loop interaction method.Its interaction mode has also not truly given the digital world the same consciousness and perception as the physical world.Taking medicine as a case study, the prospective applications and challenges of generative artificial intelligence models in metaverse organisms were explored, including digitizing biological cells, and building connections between digitized cells and digital neurons, in order to promote metaverse life forms to have perception and biochemical reactions consistent with the physical world, thereby empowering the development of the medical field.In response to the current advantages and disadvantages of the metaverse and generative artificial intelligence models, the clever design of human-machine collaboration mechanisms was discussed to promote conscious interaction between humans and metaverse organisms in medicine.

    Nowadays, the demand for efficient human avatars modeling is becoming increasingly urgent since metaverse has attracted more and more attention.Creating human avatars from human image datasets has always been a popular topic in the field of computer vision.3D human avatars synthesis can be regarded as a sub-module of 3D reconstruction focusing on reproducing the complex articulated body and surface details of human.A comprehensive survey of the literature related to the human reconstruction in recent years was conducted, including the work of full-body avatars, talking-head and clothing modeling.By analyzing and summarizing existing work, human avatars synthesis technologies were divided into five categories: mesh-based methods, image-based methods, voxel-based methods, implicit methods and hybrid methods due to the features of their pipelines.Firstly, the basic principles of them were introduced respectively.Secondly, the realization based on related work was discussed and then the advantages and disadvantages of methods respectively were pointed out.Thirdly, the datasets and metrics for model quality evaluation were introduced.Besides, an overview of various applications was given.Finally, the future directions of human avatars synthesis technology were prospected to synthesize high-quality, high-fidelity and low-latency human avatars.

    With the rapid development and in-depth application of information technology, algorithms are widely used in transportation, medical care, e-commerce, information services, public management and other fields, but their own data dependence, logical black box and general purpose characteristics also bring about data abuse in algorithm applications, algorithm discrimination in public management, algorithm manipulation in information services, algorithm collusion in market competition.In order to deal with the problems caused by the application of algorithms, countries have actively taken measures to strengthen the governance of algorithm applications.To promote the effective use of algorithms and strengthen algorithm governance, we need to further strengthen top-level design, improve governance pattern, enrich governance means, strengthen international coordination, and constantly improve the algorithm governance system.

    In view of the problems existing in the current public charity industry, such as opaque, untraceable and easy to tamper with donation information, a public charity donation traceability system model based on consortium blockchain was constructed.In the process of consensus, an improved PBFT consensus algorithm——DG-PBFT algorithm was applied, which improved the original random election of the master node to the points system election, and optimally transformd the original three-stage consensus into two-stage consensus.The system was developed on Hyperledger Fabric platform, and the Go language was used for chain code development.Four organizations corresponding to donors, recipients, charities and regulatory departments were configured.Smart contracts were designed according to functional requirements, which not only realized the traceability of donation information, but also could appeal and supervise through the traceability system.The experiment results showed that the traceability system could not only ensure the degree of decentralization, but also enhance the reliability of data, ensure the security of data, reduce the communication cost and improve the efficiency of traceability.

    Based on the provincial data of 2021 in China, an evaluation model for the digital transformation of small and mediumsized enterprises (SMEs) was constructed from five aspects: policy, facility, service, input, and effectiveness.And the AHP and entropy weight method was used to set index weight, the scoring method was used to standardize index data, and then the score of digital transformation of SMEs in 31 provinces were calculated.The score shows that there are obvious regional differences in the digital transformation of SMEs in China.The comprehensive index in the east region is the highest, and the central, western, and northeastern regions decrease successively, and are all lower than the national average.The comprehensive index has a significant positive correlation with export volume, and the correlation is higher than the correlation with GDP; the “policy” index takes the lead in the five sub-indices, and the “input” index is relatively lower.In this regard, four suggestions were put forward to promote the digital development of SMEs in China:strengthening digital financial support, lowering the threshold for using digital facilities, improving digital transformation service support, and strengthening the supply of digital workforce.
