Inadequate risk identification and management in shield tunneling can result in safety hazards, schedule overruns, and increased project costs, necessitating an effective risk assessment and decision-making framework. This research aims to develop a comprehensive risk warning and decision support model to facilitate early risk detection and informed mitigation strategies during shield tunneling construction in urban rail transit projects. The dataset includes geotechnical conditions, tunneling parameters, environmental factors, operational records, and safety monitoring data. Data sources include multi-sensors, and project logs, enabling comprehensive risk analysis and modeling. These multi-sensor inputs include cutterhead torque sensors, thrust force sensors, slurry pressure sensors, vibration and displacement sensors, as well as ground settlement monitoring instruments. The project logs consist of TBM operational logs, geotechnical investigation records, and safety monitoring logs documenting environmental and structural conditions during tunneling. To ensure data quality, pre-processing methods including Interquartile Range (IQR) for outlier detection and mean imputation for missing values are applied. Predictive risk modeling was conducted using Regularized Random Forest (RRF). Risk thresholds were established in accordance with model outputs and relevant safety standards to enable proactive early warning alerts. The decision support module leverages Proximal Policy Optimization (PPO) to recommend adaptive mitigation actions, such as tunneling parameter adjustments and structural reinforcements. Additionally, it facilitates forecasting of potential outcomes, providing dynamic, real-time feedback to the construction management team for rapid operational response. The proposed model demonstrated robust performance in early risk identification and offered actionable recommendations that enhance safety management and operational efficiency within urban shield tunneling projects. The integrated risk warning and decision support framework provides a technically sound and practical tool to improve risk mitigation efficacy, optimize construction decision-making processes, and promote the safe and efficient advancement of urban rail transit shield tunneling construction.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"14 2","pages":"223-254"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11553270","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All students had achieved a level 4 English proficiency (425–500 points) and had not received short video-assisted listening and speaking teaching. They were randomly allocated to the experimental group (45 people). A 16-week teaching experiment was carried out by using short videos from platforms such as YouTube and TikTok for auxiliary teaching and a control group (45 people, taught using the traditional textbook “New Horizons College English (Third Edition)” listening and speaking course). During the experiment, the teaching of the two groups was carried out around three units: campus life, cross-cultural communication, and career planning. The teacher was the same person to control the variables. Data were collected through several methods, including tests, questionnaires on learning motivation, classroom observations, and interviews. After conducting independent sample t-tests and ANOVA with SPSS 24.0 and qualitative coding analysis with Nvivo 12, it was found that: in terms of listening and speaking abilities, the average score of the experimental group after the test was <tex>$(78.6pm 7.2)$</tex>, which showed a significant advantage compared with the control group <tex>$(68.5pm 8.1) (t=5.82,p < 0.01)$</tex>.

This study addresses this challenge by proposing a two-tier standard coordination system of “core standards + local extensions,” effectively resolving implementation conflicts among heterogeneous standards through mechanisms such as metadata mapping and compliance checking. Building on this approach, an innovative “five-layer, three-guarantee” hierarchical decoupling platform architecture covering the entire lifecycle of archives has been designed. It clearly delineates five layers: infrastructure, data resources, core services, application functions, and user interaction, complemented by three guarantee mechanisms for standards, security, and operations, ensuring the platform's openness and scalability. To meet core business needs such as trusted archival verification, intelligent processing, and dynamic association, the research explores the application of key technologies, including blockchain for ensuring archive authenticity, artificial intelligence for intelligent classification and indexing, and digital twins for modeling dynamic mappings between archives and physical entities. At the implementation level, a four-stage model is proposed, along with a performance evaluation system encompassing infrastructure, process management, and outcome benefits, introducing business value-oriented indicators such as “completeness and accuracy of archive searches” and “cost savings from a single-set management system.” Case studies from Guangdong Power Grid demonstrate that this platform significantly improves the digitization rate of archives and the efficiency of cross-system data exchange, offering a reference solution that holds both theoretical value and practical feasibility for building a systematic and standardized archive information platform for power enterprises.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"14 2","pages":"259-294"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11553265","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148171845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, regulations, like the EU's Roam Like At Home, mandate that the roaming subscribers receive comparable service quality without additional charge from the visited operator (VO) in the roaming country. However, the currently most widely adopted roaming approach, home routed, adds significant latency because the roaming traffic traverses all the way back to the HO, while with local breakout, the subscriber is served locally by the VO, resulting in lower latency. Yet, local breakout has not been adopted by most operators, primarily because of trust issues in tracking the data used by a roaming subscriber, which currently is only done by the VO. This paper presents a trustworthy local breakout (LBO) solution that addresses the trust issue by having both the roaming user equipment and the VO keep record of data usage, thus lever-aging their opposing incentives to keep both parties accurate. In addition, the solution streamlines the 5G registration process by enabling authentication and authorization directly with the VO, thus significantly speeding up the registration. The solution utilizes verifiable credentials to record the subscriber's usage information and for the 5G registration. The analysis demonstrates that the registration process is streamlined, and usage information is now more trustworthy compared to the current LBO.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"14 1","pages":"1-36"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11440166","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147557526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional adaptive streaming approaches such as DASH and HLS operate primarily at the application layer, adjusting bitrates reactively based on buffer occupancy or short-term throughput. These strategies often fail under abrupt bandwidth fluctuations, leading to quality oscillations and excessive rebuffering. This paper proposes a cross-layer bitrate optimization framework that unifies lightweight adaptive encoding with a control-theoretic feedback loop driven by real-time network metrics. The framework jointly considers content complexity, encoder parameters, and network congestion signals to dynamically regulate bitrate across both the network and application layers. A lightweight encoder enhancement module performs perceptually guided bit allocation using saliency-aware analysis, while the control loop ensures fast convergence of target bitrate and stability against throughput variability. Extensive experiments across Wi-Fi, 4G, and simulated edge-network traces show that the proposed system achieves 30-40% bitrate reduction compared with H.264/H.265 adaptive streaming baselines, with PSNR gains up to 1.2 dB and SSIM improvements of 0.02, while reducing buffering time by over 35%. These results establish that the synergy of control-theoretic adaptation and lightweight encoding yields a scalable, low-complexity solution suitable for next-generation low-bitrate video communication systems operating on mobile and edge devices.","PeriodicalId":36697,"journal":{"name":"Journal of ICT Standardization","volume":"14 1","pages":"37-68"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11440082","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147557991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
