As governments, education departments, and academic accreditation bodies have begun to encourage schools to develop evidence-based decision-making and innovation systems, learning analysis techniques have shown great advantages in decision-making aid and teaching evaluation. After integrating relevant algorithms and technologies in artificial intelligence and machine learning, learning analysis has achieved higher analysis accuracy. In order to realize the recognition of students' classroom behaviors such as standing up, sitting up, and raising hands and improve the recognition accuracy and recall rate, multi-modal data such as human key point information and RGB images are used for experiments. To further improve the feature extraction capability of the model, features are extracted from the improved ResNet-50 and EfficientNet-B0 models, and bilinear fusion is performed to further improve the recognition accuracy of the models.

The literature emphasizes the crucial role of state-owned enterprises (SOEs) in fostering economic growth and addressing public demands. However, ensuring the sustainable development of SOEs requires further research to investigate sustainable project management with a focus on value creation. Accordingly, the authors conducted a case study of a prominent real estate SOE in China to examine how SOEs can alter their project management practices and achieve a more sustainable business model. The findings reveal that adopting a whole life-cycle management system can promote value refinement, optimization, and co-creation, enabling SOEs to achieve value creation through sustainable management. This study offers useful insights for policymakers and business executives in China and contributes to the literature on sustainable project management and value creation.

Aiming at the problem that most existing models of art sentiment analysis only consider text encoding from the word level, this paper proposes a novel long and short-term memory network-based krill herd algorithm for explainable art sentiment analysis in interior decoration environment. Firstly, multi-scale convolution is used to capture local correlation of different granularity, so as to obtain more semantic information of different levels and form richer text representation. Then, a gating mechanism is introduced to control the path of sentiment information flowing to the aggregation layer. An improved krill swarm algorithm based on cosine control factor and Cauchy factor is proposed to solve the model. Finally, the full connection layer and argmax function are used to achieve sentiment classification. The experimental results show that compared with other advanced models, the proposed model can improve the accuracy of emotion classification by 2.3% and 0.8% respectively on two public data sets of IMDB and Yelp2014, and obtain the minimum root mean square error (RMSE).

E-learning is an online educational system that uses electronic and technology tools and the internet. To facilitate the acquisition of knowledge, students can consult materials and interact directly with lecturers via e-learning educational systems. The method for developing an intelligent querying system for e-learning is suggested in this research. The knowledge base of the system is structured using the knowledge model combining an ontology and the two-layer knowledge graph, called Rela-KG model. The searching problems for knowledge content are studied and solved. The technique is applied to create an intelligent querying system on the course of Database Foundation in Information Technology (IT) at the university. This technique attempts to assist students in reviewing lectures and better comprehending course material through independent study. The experimental results indicate that it would be anticipated to support student access to online learning resources.

Due to the differences of students' English proficiency and the rapid changes in reading interests, online personalized English reading recommendation is a highly challenging problem. Although some works have been proposed to address the dynamic change of recommendation, there are two issues with these methods. First, it only considers whether students have read the recommended articles. Second, these methods often fail to capture the real-time changing interests of users. To address the above challenges, a deep Q-network based recommendation framework was proposed. The authors further use the user's behavior and scores as reward information to get more user's feedback. In addition, a personalized adaptive module was introduced to capture the short-term interests on the fly and utilized the consistent loss of KL divergence to distill the knowledge from the online model. Extensive experiments on the offline and online dataset in the IWiLL website demonstrate the superior performance of the method.

This paper aims to visualise three financial distress outlooks using computer simulations. The financial distress exposure for airport operations in Malaysia between 1991 and 2021 is given by Altman Z”-score and modelled by the multivariate generalized linear model (MGLM). Seven determinants contributing to the financial distress from literature are examined. The determinant series are fitted individually by using linear model with time series components and autoregressive integrated moving average models to forecast values for the next 10 financial years. Future short- to long-term memory effects following COVID-19 are apparent in time series plots. In the simulations, the MGLM procedure utilised Gaussian, gamma, and Cauchy probability distributions associated with expectations and challenges of doing business as well as uncertainties in the economy. The underlying trends of realistic, optimistic, and pessimistic financial distress outlooks insinuate that the increasing risk of financial distress of airport operations in Malaysia is expected to continue for the next decade.

Immersive analytics (IA) is a fast-growing research field that concerns improving and facilitating human sense making and data understanding through an immersive experience. Understanding the suitable application scenario that will benefit from IA enables a shift towards developing effective and meaningful applications. This paper aims to explore tasks and scenarios that can benefit from IA by conducting a systematic review of existing studies and mapping them according to the multi-level typology for abstract visualization tasks, which is also known as the what-why-how framework. The study synthesizes several works to answer the why within the context of multiple levels of specificity. In addition, this study also explores the application domains and IA guiding scenarios to address when scenarios best integrate with IA. Then, the paper discusses the IA evaluation types and research methods to evaluate an IA application that can promote effective user engagement in IA. Finally, the limitations and potential future works are discussed.

With the advancement of technology, the metaverse image is used to improve the success rate of surgical. The purpose of this study was to understand the acceptance of extended reality surgery by different populations of medical experts and patients. The main reason for using a triangular mixed model for the study is because of the small amount of relevant research data for this study, quantitative research, exploratory research, and cross-sectional research can avoid some human interference and reduce error. The results of the study data showed that the image model, interaction design, surgeon, and clarity of use of the head-mounted display with metaverse technology by the expert group were conducive to improved surgical success rates. Metaverse surgery offers opportunities for modern digital surgery and can effectively improve the expert's ability to promote the smoothness of physical indicators during the procedure. This study is pioneering the role of a metaverse in facilitating surgery from the dual perspective of medical experts and patients.

The increased cyberattack frequency and ferocity have alerted the fintech industry in detecting existential security threats and risks. Various authentication mechanisms have been deployed to countermeasure cyberattacks; whether these deployed solutions fulfil the security and technical standards has not been significantly investigated. This article proposed an uAuth security analytics framework to evaluate the deployed user authentication mechanisms. Subsequently, the technical evaluation study covered ten major commercial banks in Malaysia, whereas 120 respondents aged 18 to 25 participated in the user awareness study. The result found that mobile banking enforces more robust user authentication mechanisms than internet banking in Malaysia. As 80% of the Malaysia fintech systems only ranked as Level 3 of the uAuth security analytics framework, the authors urge Malaysia fintech industry to enhance their authentication factor, login and transaction verification methods, password policy, as well as readiness for quantum-safe security technologies.
