摘要BACKGROUND:This study aims to evaluate the immediate and 12-month effects of communitybased first-aid training on public knowledge and attitude,assess satisfaction,and identify factors associated with score changes.METHODS:This was a prospective study.In 2022-2023,a total of 2,010 community residents in Hainan Province received first-aid training and completed structured questionnaires at baseline,immediately after training,and at 3,6,and 12 months after training.First-aid knowledge was assessed through 33 items,with a maximum total score of 33.First-aid attitude was evaluated using seven items,totaling a maximum score of 21.Satisfaction was measured on a 5-point Likert scale.Paired-sample t-tests were used to compare baseline and post-training scores,repeated-measures analysis of variance(ANOVA)was used to examine time effects,and multiple linear regression was used to analyze factors associated with score changes.RESULTS:The satisfaction score with the training was high(mean score>4.3 for all items).The first-aid knowledge and attitude scores increased significantly after training(first-aid knowledge at baseline,14.90±7.63;immediately after training,20.70±5.72,P<0.001;and attitude at baseline,17.52±2.29;immediately after training,17.89±1.54,P<0.001).At 12 months after training,knowledge scores declined slightly compared with those immediately after training but remained above baseline(time effect P<0.001),whereas attitude scores remained stable(time effect P<0.001).Knowledge improvement was greater among middle-income participants and less among participants with lower levels of education,those in professional occupations,widowed individuals,or those who had previously received first-aid training.Attitude improvements were more pronounced among male participants,younger participants,and those in the agriculture or sales/service sectors.CONCLUSION:Community-based first-aid training improved public first-aid knowledge and attitude and was well received by participants.While knowledge levels declined somewhat over time,attitude remained relatively stable,highlighting the importance of continuous reinforcement training.Personalized reinforcement strategies may be particularly beneficial for individuals with lower levels of education,specific professional backgrounds,widowhood,or prior training experience to further enhance training effectiveness.

摘要Wetting deformation in earth-rockfill dams is a critical factor influencingdam safety.Although numerous mathematical models have been developed to describe this phenomenon,most of them rely on empirical formulations and lack prior knowledge of model parameters,which is essential for Bayesian parameter inversion to enhance accuracy and reduce uncertainty.This study introduces a datadriven approach to establishing prior knowledge of earth-rockfill dams.Driving factors are utilized to determine the potential range of model parameters,and settlement changes within this range are calculated.The results are iteratively compared with actual monitoring data until the calculated range encompasses the observed data,thereby providing prior knowledge of the model parameters.The proposed method is applied to the right-bank earth-rockfilldam of Danjiangkou.Employing a Gibbs sample size of 30,000,the proposed method effectively calibrates the prior knowledge of the wetting model parameters,achieving a root mean square error(RMSE)of 5.18 mm for the settlement predictions.By comparison,the use of non-informative priors with sample sizes of 30,000 and 50,000 results in significantly larger RMSE values of 11.97 mm and 16.07 mm,respectively.Furthermore,the computational efficiencyof the proposed method is demonstrated by an inversion computation time of 902 s for 30,000 samples,which is notably shorter than the 1026 s and 1558 s required for noninformative priors with 30,000 and 50,000 samples,respectively.These findingsunderscore the superior performance of the proposed approach in terms of both prediction accuracy and computational efficiency.These results demonstrate that the proposed method not only improves the predictive accuracy but also enhances the computational efficiency,enabling optimal parameter identificationwith reduced computational effort.This approach provides a robust and efficientframework for advancing dam safety assessments.

摘要Objectives:This study aimed to evaluate the effectiveness of family-based nursing interventions in improving mothers’knowledge,attitudes,and self-efficacy to prevent stunting among children under 2 years of age in Indonesia.Methods:A quasi-experimental study was conducted from June to December 2024 in Alor District,East Nusa Tenggara,Indonesia.Sixty mothers of children aged 0–24 months were recruited using convenience sampling and assigned to either an intervention group(n=30)or a control group(n=30).The intervention group received seven structured sessions of a family-based nursing intervention grounded in Family-Centered Care and Social Cognitive Theory.In contrast,the control group received routine health education from local community health centers.Knowledge,attitudes,and self-efficacy were measured using validated questionnaires at baseline,post-intervention,and a three-month follow-up.Data were analyzed using independent-sample t-tests and a mixed repeated-measures analysis of variance.Results:All 60 participants completed the study.Independent-sample t-tests revealed no significant differences between the two groups at baseline for knowledge(t=−0.682,P=0.498),attitudes(t=0.655,P=0.515),and self-efficacy(t=1.671,P=0.100).A mixed repeated-measures analysis of variance demonstrated significant group,time,and group×time effects on knowledge,attitudes,and self-efficacy(all P<0.001).Pairwise comparison revealed that the scores at post-intervention and three-month follow-up were significantly higher in the intervention group for all three variables(all P<0.001).Conclusions:The family-based nursing intervention effectively enhanced maternal knowledge,attitudes,and self-efficacy regarding stunting prevention.These findings underscore the importance of incorporating structured,family-centered interventions into community-based public health programs to reduce the risk of stunting.

摘要A substantial amount hazardous chemical accident(HCA)data have been accumulated in the form of unstructured textual data,making systematic analysis and utilization challenging.More importantly,manually identifying and analyzing key information from a considerable quantity of accident data is inefficient and highly susceptible to subjective bias.To efficiently unlock the value of HCA investigation reports and uncover underlying accident patterns,a semi-automated method for knowledge graph(KG)construction has been developed to model the HCA data.First,an ontology that accurately expresses key factors of HCAs is established.Second,an automated method is developed for the identification,standardization,and enhancement of accident factors,which combines deep learning(DL)and natural language processing(NLP)techniques.Specifically,the deep neural network model,named interaction region and type information(IRTI)is proposed to extract accident factors and their relationships from lengthy HCA data with complex overlapping issues.Non-standard accident factors are standardized using ChatGPT-4 in combination with the proposed text clustering model,named contrastive learningbased short text clustering(CLSTC).The processed accident factors are used to construct the hazardous chemical accident knowledge graph(HCAKG).Finally,the risk factors in the HCAKG are statistically analyzed,and their internal topological relationships are explored to facilitate quantitative analysis.Data from HCA investigation reports are used to demonstrate the effectiveness of this method.The result shows that it improves the accuracy and efficiency of accident data analysis,promoting better risk assessment and management strategies.

摘要With the large-scale deployment of the Internet of Things(IoT)devices,their weak securitymechanisms make them prime targets for malware attacks.Attackers often use Domain Generation Algorithm(DGA)to generate random domain names,hiding the real IP of Command and Control(C&C)servers to build botnets.Due to the randomness and dynamics of DGA,traditional methods struggle to detect them accurately,increasing the difficulty of network defense.This paper proposes a lightweight DGA detection model based on knowledge distillation for resource-constrained IoT environments.Specifically,a teacher model combining CharacterBERT,a bidirectional long short-term memory(BiLSTM)network,and attention mechanism(ATT)is constructed:it extracts character-level semantic features viaCharacterBERT,captures sequence dependencieswith the BiLSTM,and integrates theATT for key feature weighting,formingmulti-granularity feature fusion.An improved knowledge distillation approach transfers the teacher model’s learned knowledge to the simplified DistilBERT student model.Experimental results show the teacher model achieves 98.68%detection accuracy.The student modelmaintains slightly improved accuracy while significantly compressing parameters to approximately 38.4%of the teacher model’s scale,greatly reducing computational overhead for IoT deployment.

摘要Against the backdrop of China's aging society and under the macro policy of building a Healthy China proposed at the Fifth Plenary Session of the 18th Central Committee of the Communist Party of China,the dissemination of Traditional Chinese Medicine(TCM)health knowledge has emerged as particularly crucial and imperative.This paper systematically examines the current status of TCM health knowledge dissemination in China.It identifies multiple challenges in the dissemination process,including multidimensional constraints related to content dissemination,media channels,and audience characteristics.Drawing on these findings,this paper proposes a strategic framework centered on high-quality content,with standardized media platforms as key hubs and audience empowerment as the ultimate goal.
摘要This paper introduces MobiIris,a lightweight deep network for mobile iris recognition that enhances attention and specifically addresses the balance between accuracy and efficiency on devices with limited resources.The proposed model is based on the large version of MobileNetV3 and adds more spatial attention blocks and an embedding-based head that was trained using margin-based triplet learning,enabling fine-grained modeling of iris textures in a compact representation.To further improve discriminability,we design a training pipeline that combines dynamic-margin triplet loss,a staged hard/semi-hard negative mining strategy,and feature-level knowledge distillation from a ResNet-50 teacher.Finally,we investigate the use of post-training float16 quantization to reduce memory footprint and latency for deployment on mobile hardware.Experiments on the challenging CASIA-IrisV4-Thousand dataset show that the full-precision MobiIris model requires only 12 MB of storage and 27 ms inference latency,while achieving an EER of 1.409%,VR@FAR=1%of 98.184%,and CMC@1 of 94.785%,closely matching a ResNet-50 baseline that is more than 7×larger and slower.Under post-training quantization,the model shrinks to 5.94 MB with 13 ms latency and maintains a competitive balance between accuracy and efficiency compared to other optimized variants.These results demonstrate that a coherent combination of lightweight architecture design,attention mechanisms,metric-learning objectives,hard negative mining,and knowledge distillation yields a practical iris recognition solution suitable for secure,real-time authentication on mobile and embedded platforms.

摘要Few-shot knowledge graph completion refers to inferring missing entity using limited instances.A key challenge lies in entity representation,which is complicated by diverse neighbor attributes.Although the entity's neighborhood topology holds potential to address this,its significance is overlooked in current research.In this paper,we propose a structure-aware graph attention network for few-shot knowledge graph completion.Firstly,to enhance entity representations,we design a structure-aware graph attention encoder to capture the graph's structural features of nodes,generating embedding for entity pairs.Secondly,a semantic prototype matching network is employed to compute the prediction score.Experiments on the NELL-One and Wiki-One datasets show that our proposed model outperforms the best baseline models by 0.021,0.026,0.039,0.032 and 0.016,0.064,0.043,0.040 in terms of MRR,Hits@10,Hits@5,and Hits@1 metrics,respectively.This demonstrates that our model can effectively leverage neighborhood topological information to improve the accuracy of knowledge completion,and achieve a better generalization.

摘要The proliferation of diverse entities within distribution network has led to an increase in the scale and complexity of data asset interactions,exacerbating security risks,such as unauthorized access,data tampering,and forgery.In response to these challenges,this study introduces a novel framework that enhances the protection of data assets.It incorporates a multi-dimensional knowledge graph(MDKG)to refine access control and overcome current limitations by integrating a comprehensive set of data asset attributes,roles,policies,and permissions.This approach fosters the development of a nuanced and adaptable access-control mechanism.Furthermore,the framework integrates multiple topology(MTP)for holistic security risk detection,leveraging attention mechanisms,and cross-fusion to adapt to the dynamic data security landscape.Empirical evaluations affirm the effectiveness of MDKG-based access control,whereas comparative experiments demonstrate the superiority of the MTP-based security risk model over existing models.The framework was proven to be effective in countering security risks.This study provides innovative perspectives on data asset protection and establishes a solid foundation for the advancement of smart grid technology.

摘要The short-term forecasting of multiple loads is crucial for the optimization and scheduling of integrated energy system(IES).However,the load within the IES exhibits diversified and strongly coupled characteristics,which seriously affects the forecast accuracy.Moreover,only using deep learning forecasting methods cannot analyze the factors that affect the forecast results,which is not conducive to guiding the optimization and scheduling of comprehensive energy systems.Therefore,a multivariate load forecasting model based on knowledge-guided multi-task spatial-temporal synchronous graph convolutional network is proposed.Firstly,the user clusters are classified according to the energy-using characteristics of different buildings.Then,the domain knowledge base is built by combining the dimensionless trends of different groups and expert experience.At the same time,the input features are filtered based on the improved maximum information coefficient method to construct spatialtemporal graph data,forming a more refined and efficient input sample data.Finally,the knowledge-data fusion model for multivariate load forecasting is constructed to predict local fluctuations of the multivariate load series and reconstruct the load ratio.The IES data set of Arizona State University Tempe Campus is taken as a test case.The results show that the proposed method is interpretable,has higher forecast accuracy and has better generalization ability.
