Objective To analyze the current situation and influencing factors of work engagement of neurology nurses. Methods Using the convenient sampling method, a cross-sectional survey was conducted among nurses in the department of neurology in a Class III and Class A general hospital in Beijing from April to May 2022. The self-designed general data questionnaire, the work engagement scale and the Chinese version of the perceived stress scale were used to survey the nurses in the department of neurology. Results In this study, a total of 660 questionnaires were distributed and 630 were recovered, with a recovery rate of 95. 45%. Totally 630 questionnaires were valid, with an effective rate of 100. 00%. Of the 630 neurology nurses, 34 were male (5. 40%) and 596 were female (94. 60%). The score of work engagement of 630 neurology nurses was (35. 15 ± 5. 34), and the data difference was statistically significant (P＜0. 05). The results of univariate analysis showed that there were statistically significant differences in the scores of work engagement of neurology nurses in terms of age, employment relationship, technical title, working years and children's situation (P＜0. 05). The total score of perceived stress of neurology nurses was (36. 76 ± 8. 10), and the total score of work engagement was positively correlated with the score of sense of loss and perceived stress (P＜0. 05), and negatively correlated with the score of tension (P＜0. 05). The results of multifactor analysis showed that the sense of loss of control, employment relationship, and working for 1～10 years were the independent influencing factors of work engagement (P＜0. 05). Conclusion There are several factors affecting the work engagement of neurology nurses. As clinical nursing managers, they can adopt effective scientific management methods and take effective measures to relieve the psychological pressure of nurses, reduce the level of rumination thinking, and positively guide the establishment of positive emergency psychology, so as to improve the degree of nurses' work engagement, and ultimately achieve the goal of improving nursing quality and patient satisfaction.

Both human physiological activity and random noise have an impact on the accuracy of cerebral blood oxygen measurement data. It is necessary to solve some noise interference encountered during signal acquisition to improve the measurement accuracy of cerebral blood oxygen detection. This study proposes a denoising method of cerebral oximetry signals by combining ICEEMDAN (Improved Complete Empirical Mode Decomposition with Adaptive Noise) and SampEn (Sample Entropy). Specifically, the modal decomposition of the cerebral blood oxygen signal is performed using ICEEMDAN to obtain the IMF components with different time complexity. The time complexity of each IMF (Intrinsic Mode Function) component is judged by the sample entropy value, and the appropriate component is selected to reconstruct the signal according to the sample entropy value of each IMF component, thus realizing the noise removal of the original signal. Experimental results show that the proposed method can effectively remove the original cerebral blood oxygen signal and realize the accuracy improvement of the collected data, thus improving the accuracy of cerebral blood oxygen detection.

Evaluating the coordination among water resources, social economy, and ecological environment could offer guidance for the utilization and management of water resources in the Yellow River. An evaluation index system for water resources carrying capacity was constructed based on the subsystems of water resources, social economy, and ecological environment. The VIKOR method was utilized to assess the water resources carrying capacity of nine provinces along the Yellow River from 2008 to 2021. Additionally, the Mantel test method was introduced to analyze the categories of water resources carrying capacity and their influencing factors. The results show that the water resources carrying capacity of nine provinces along the Yellow River have exhibited a continuous upward trend from 2008 to 2021. With the enhancement of social and economic development and ecological environment protection, the level of water resources carrying capacity has notably increased after 2015. Spatially, there is a pattern of strong capacity in the west, followed by the east, and weaker capacity in the middle. Among them, Qinghai is the strongest, and Ningxia is the weakest. The types of water resources carrying capacity vary in each province. Qinghai, Gansu and Shaanxi fall under the category of water resources endowment type, while Ningxia and Inner Mongolia are classified as water resources-social economy type. Sichuan, Shanxi, Henan, and Shandong are categorized as comprehensive type. Water resources endowment forms the basis of water resources carrying capacity in nine provinces along the Yellow River. Factors such as water production modulus, per capita water resources, and precipitation depth are key determinants of the water resources subsystem. Moreover, there is a high reliance on the social economy and ecological environment subsystem, which necessitate enhancement through industrial upgrading, improving water use efficiency, and ecological environment protection.

Objective To study changes and correlation of peripheral bold endothelial progenitor cells (EPCs) and serum bFGF, VEGF and MMP-9 in rats with peripheral nerve injury (PNI). Methods Forty-two SD rats were divided into the control group, the PNI 1 d group, the PNI 3 d group, the PNI 5 d group, the PNI 7 d group and the PNI 14 d group according to random number table method, with 7 rats in each group. The sciatic nerve injury model was established in all groups except the control group. In each group, blood samples were collected by living heart puncture at a predetermined time point. Mononuclear cells were extracted by Ficoll density gradient centrifugation. CD34 and CD133 double positive cells were labeled with EPCs, and the number of EPCs in each group was detected by flow cytometry. The contents of bFGF, VEGF and MMP-9 in peripheral blood of each group were detected by enzyme-linked immunosorbent assay, and the correlation between the number of EPCs and bFGF, VEGF and MMP-9 was analyzed. Results Compared with the control group, EPCs in peripheral blood were increased in the PNI 3 d group, the PNI 5 d group and PNI 7 d group. bFGF contents in peripheral blood were increased in the PNI 3 d group, the PNI 5 d group, the PNI 7 d group and the PNI 14 d group, and VEGF contents in peripheral blood were increased in the other groups. The content of MMP-9 in peripheral blood was increased in the PNI 5 d group, the PNI 7 d group and the PNI 14 d group (P＜0.05). The number of EPCs in peripheral blood in the PNI 5 d group and the PNI 7 d group was positively correlated with serum bFGF level (r=0.784 and 0.788, P＜ 0.05) and serum VEGF level (r=0.889 and 0.852, P＜0.05). The number of EPCs in peripheral blood of the PNI 5 d group, the PNI 7 d group and the PNI 14 d group was positively correlated with serum MMP-9 level (r=0.788, 0.852 and 0.873, P＜ 0.05), and it was positively correlated with serum VEGF level (r=0.889 and 0.852, P＜0.05). The number of EPCs in peripheral blood was positively correlated with serum MMP-9 level in the PNI 5 d group, the PNI 7 d group and the PNI 14 d group (r=0.788, 0.852 and 0.873, P＜0.05). Conclusion EPCs, bFGF, VEGF and MMP-9 are involved in the pathophysiological process of blood supply repair after PNI. [ABSTRACT FROM AUTHOR]

During the new urbanization construction and management, data integration of BIM(geographic information system) and GIS(building information modeling) is not only beneficial for realizing comprehensive implementation of buildings, but also obtaining the spatial analysis and indoor and outdoor integrated expression with the support of comprehensive outdoor information. What is noticeable is that the current challenge faced two different data formats of data, BIM and GIS, fails to directly achieve data interoperability. Therefore, the differences between IFC and CityGML in document format were analyzed initially, and the conversion of multiple simple building IFC models to CityGML3. 0 LOD2 and LOD3 was implemented. Secondly, concerning the semantic loss in the above data integration experiments, the CityGML3. 0 data format of GIS was extended, and a CityGML B-Con extension model was proposed, as well as a one-to-one mapping relationship from IFC to CityGML3. 0 was improved. Finally, the conversion of multiple IFC models of buildings with different complexity levels to the CityGML B-Con extension model is successfully implemented. The experimental results show that the CityGML B-Con model was capable of achieving data integration between BIM and GIS. Standing from a macro perspective, the implementation qualify of the converted building appearance can be enhanced. Standing from a micro perspective, the subclasses of BuildingConstructiveElement and BuildingInstallation are distinguished, and building components, such as IfcStair, IfcRamp, and IfcBeam can be converted into CityGML through one-to-one mapping, which overcomes the demerits of the original CityGML standard in the representation of building components, effectively reducing the loss of semantic information from BIM source data.

In view of the characteristics of coal mines in Shaanxi and Inner Mongolia, such as large coal seam burial depth, large thickness, hard roof, difficult to collapse in time during mining and frequent occurrence of mine tremors, taking the fully mechanized top coal caving face in Longwanggou coal mine with extra thick coal seam as the engineering background, through the analysis of the characteristics of ground pressure and main control factors under the conditions of typical thick and hard roof, theoretical analysis combination of on-site measurement and engineering practice was used to explore the factors and prevention and control techniques induced by thick hard top plate fracture type mining earthquakes. It is believed that the mine shock phenomenon in the working face is mainly caused by single or multiple factors such as hard rock strata of high roof are not easy to collapse in time after mining, and caused by stress superimposition and transmission. The key is to deal with the high hard roof of the working face from two gateways and withdrawal channels to avoid the accumulation and propagation of elastic properties, block the stress transmission path, change the weighting step distance through manual intervention such as hydraulic fracturing, reduce the suspended roof structure, release energy in advance, reduce the occurrence frequency and hazard degree of mine shock from the source, and then realize the stability control of the surrounding rock of the stope, providing theoretical reference for the prevention and control technology of mine shock under the condition of hard roof.
