However, multiple postoperative adverse events associated with ischemia may be caused by excessive inflation pressure and duration. We aimed to evaluate the degree of tourniquet-induced ischemia using a noninvasive continuous real-time monitoring method and the relationship between changes in tissue oxygen saturation (StO2) and blood biochemical markers of ischemic injuries in patients undergoing arthroscopic knee surgery. Methods This was a prospective observational study using near-infrared spectroscopy (NIRS). Data were collected from 29 consecutive patients who underwent arthroscopic procedures. Twenty-five patients underwent anterior cruciate ligament reconstruction, and four underwent meniscal repair. We investigated tourniquet‐induced changes in StO2, monitored using NIRS, and blood biochemical markers of ischemic injuries. Results A significant decrease in the mean StO2 from the baseline was...

It can realize the ubiquitous and deep interconnection of the entire chain of human, financial, and material from R&D and design to production, management, and service. Promoting the chain-network integration of blockchain and enterprise networks is expected to solve the dilemma of efficiency and risk. We adopt a comprehensive literature research method to focus on the theoretical evolution and application development of enterprise networks and blockchains, explain the main logic of the integration of blockchain and enterprise network theory and chain networks from a theoretical perspective, give the definition of enterprise networks, and innovate to establish chain- network integration model and correlation measurement model. It provides basic theoretical support and practical reference in order to open up the information, trust and credit barriers between the network and the network based on the blockchain technology for the industrial Internet, complex enterprise networks or hyper-networks, and to improve the overall operating efficiency.

Traditional trustworthiness methods are gradually losing their advantages due to the shackles (single point of failure and fairness query) or elbows (multiple iterations and performance bottlenecks) of the trust intermediary. Undoubtedly, the trustworthiness method of blockchain and the mechanism for resolving disputes are extremely important to the distributed operation mode of enterprise networks. We proposed three modes of blockchain and enterprise network integration and focused on the private chain mode of blockchain and star structure enterprise network integration, the alliance chain mode of blockchain and linear structure enterprise network integration. It also proposes applicative and distributed operation solutions based on blockchain because of its characteristic like decentralization and non-repudiation for enterprise network autonomy scenarios. Our research introduces the blockchain technology into the construction of the logistics and information flow ecosystem to master the laws of information resource flow, optimize the management of information resources, realize the innovation and development of industrial clusters, and provide theoretical reference and practical guidance.

We selected the college students from Guangzhou X College as the experimental samples, and conducted a study on the distinction between the experimental group and the control group. In the experimental group, the basic physical condition was learned through Functional Movement Screening (FMS). Then carried out cause analysis and functional adjustment exercises for low-scoring items. Based on the weakness of upper limbs and core strength discovered by the experimental group during the test, we conducted targeted online physical training for 8 weeks. A comparative analysis based on the physical test before and after training and the FMS score of the experimental group. After training intervention, it has a significant impact on Shoulder Mobility, Active Straight Leg Raise, Rotary Stability and total score in FMS, but it has a counter-effect on the Hurdle Step, and other test actions have different gender validity. Through the physical test, the data of the experimental group has been significantly improved (P<0.01), but it is still at the passing level, which shows that the physical fitness of the college students is very poor. Although this physical training method is limited to home conditions and training tools, it also effectively improve the physical fitness of college students under epidemic situation. In addition, the results show that the method has a more significant effect on female.

However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.

In this paper, a new type of data privacy protection strategy based on the additive aggregation function is proposed (hereafter referred to as DPPA). On the one hand, applying the superposition property of the node data, the paper introduces the class aggregation protocol. On the other hand, taking advantage of the algebraic properties of the polynomials and the correlation properties of the superposed data, it can reduce the data of the header files of the data packages, and reduce the data size, while improving the privacy preservation. Simulation results show that DPPA can effectively protect data privacy, and get accurate data fusion results, while reducing the amount of data traffic.
