Graphite is a rare and important nonmetallic mineral. Till 2017, the global graphite resource reserves had exceeded one billion tons, which are mainly distributed in China (0.45 billion tons), Mozambique (0.14 billion tons), Madagascar (0.1 billion tons), Turkey (0.09 billion tons), Brazil (0.07 billion tons), and Tanzania (0.07 billion tons). These six countries include about 92% of the global graphite resource reserves, of which China accounts for about 45% of the world's total resource reserves. 展开更多

BACKGROUND Systematic review focuses on the visual patient avatar(VPA)technology,a tool designed to enhance situational awareness in anesthesia by transforming traditional numerical data into intuitive visual displays.AIM To explore how VPA can improve perceptual performance,reduce cognitive load,and increase user acceptance,potentially leading to better patient outcomes.METHODS The review is based on 14 studies conducted between 2018 and 2023 in five different hospitals across Europe.RESULTS These studies demonstrate that VPA allows clinicians to perceive and recall vital signs more efficiently than conventional monitoring methods.The technology’s intuitive design helps reduce cognitive workload,indicating less mental effort required for patient monitoring.Users’feedback on VPA was generally positive,highlighting its potential to enhance monitoring and decision-making in highstress environments.However,some users noted the need for further development,particularly in visualization design and data integration.CONCLUSION Review concludes that VPA technology represents a significant advancement in patient monitoring,promoting better situational awareness and potentially improving safety in perioperative care. 展开更多

Most ground faults in distribution network are caused by insulation deterioration of power equipment.It is difficult to find the insulation deterioration of the distribution network in time,and the development trend of the initial insulation fault is unknown,which brings difficulties to the distribution inspection.In order to solve the above problems,a situational awareness method of the initial insulation fault of the distribution network based on a multi-feature index comprehensive evaluation is proposed.Firstly,the insulation situation evaluation index is selected by analyzing the insulation fault mechanism of the distribution network,and the relational database of the distribution network is designed based on the data and numerical characteristics of the existing distribution management system.Secondly,considering all kinds of fault factors of the distribution network and the influence of the power supply region,the evaluation method of the initial insulation fault situation of the distribution network is proposed,and the development situation of the distribution network insulation fault is classified according to the evaluation method.Then,principal component analysis was used to reduce the dimension of the training samples and test samples of the distribution network data,and the support vector machine(SVM)was trained.The optimal parameter combination of the SVM model was found by the grid search method,and a multi-class SVM model based on 1-v-1 method was constructed.Finally,the trained multi-class SVM was used to predict 6 kinds of situation level prediction samples.The results of simulation examples show that the average prediction accuracy of 6 situation levels is above 95%,and the perception accuracy of 4 situation levels is above 96%.In addition,the insulation maintenance decision scheme under different situation levels is able to be given when no fault occurs or the insulation fault is in the early stage,which can meet the needs of power distribution and inspection for accurately sensing the insulation fault situation.The correctness and effectiveness of this method are verified. 展开更多

Political skill is a critical interpersonal competency.However,the self-reported political skill scale is unsuitable for personnel selection beacuse it may lead to socially desirable responses,thereby compromising the authenticity of the test scores.Consequently,the absence of a valid assessment method limits the application of political skill in selection con-texts.In this study,we applied the situational judgment test(SJT)method to measure political skill and conducted two sub-studies to evaluate the reliability and validity of the situational judgment test of political skill(SJT-PS).Study 1 focused on the development and initial testing of the SJT-PS.The results demonstrated that the SJT-PS possessed strong structural validity and reliability.Study 2 aimed to assess the criterion-related and incremental validity of the SJT-PS.To evaluate the predictive validity of the SJT-PS in selection contexts,we first compared the correlations between the SJT-PS and self-reported political skill with social desirability.Subsequently,we selected team-member exchange(TMX)and workplace popularity as criteria.The results indicated that the SJT-PS was less affected by social desirability,while self-reported political skill exhibited a significant positive correlation with social desirability.Additionally,the SJT-PS positively pre-dicted TMX and workplace popularity and demonstrated incremental validity over the self-reported political skill scale. 展开更多
