Abstract

Many mobile health information systems are developed based primarily on technical requirements, while user acceptance is often assessed only after deployment and rarely integrated into the design process. This study addresses that gap by incorporating user acceptance evaluation as a design-informed feedback mechanism in the development of a district-level mobile health information system for maternal care. An applied research approach was used through system development, pilot deployment across five sub-districts, and post-use evaluation involving 74 active users. User acceptance was assessed using structured questionnaires covering perceived usefulness, perceived ease of use, consultation feature acceptance, and automated conversational support acceptance. The results showed high overall acceptance, with direct consultation with local midwives receiving the highest score (mean = 4.41; SD = 0.52), followed by consultation routing effectiveness (mean = 4.35; SD = 0.55). Perceived ease of use was positively associated with consultation feature acceptance (ρ = 0.46, p < 0.01). Automated conversational support was positively perceived but obtained lower scores (mean = 3.92) than human-based consultation features, indicating its complementary role. These findings demonstrate that user acceptance evaluation can provide actionable evidence for iterative system refinement and support the development of context-aware mobile health systems for maternal care.

Abstract

Large Language Models (LLMs) have experienced rapid development and have been established as the dominant paradigm in modern Natural Language Processing (NLP), with high performance demonstrated across various language understanding and generation tasks. Increasing architectural complexity has led to the need for a structured conceptual framework to explain how architectural design, training paradigms, and inference mechanisms are collectively associated with model behavior. A conceptual and analytical review of LLMs is presented in this article through an examination of the relationship between Transformer-based architectures, multi-stage training processes, and the resulting capabilities and limitations. Encoder-only, decoder-only, and encoder–decoder architectural variants are examined in relation to structural characteristics and functional implications. The roles of pretraining, supervised fine-tuning, and instruction tuning are analyzed to clarify how output characteristics are shaped during model development. This study emphasizes how architectural and training strategies causally influence generative capabilities and inherent limitations. Fundamental issues, including hallucination, bias, data dependency, computational cost, and evaluation challenges, are critically examined as consequences of the probabilistic modeling paradigm adopted in LLMs. This review contributes a structured analytical perspective for evaluating LLMs design choices and their operational consequences, supporting more informed development and deployment practices.

Abstract

Brain tumor segmentation from Magnetic Resonance Imaging was an essential step for therapy planning, prognosis evaluation, and treatment monitoring in glioma patients. Manual delineation required substantial time and was prone to inter-observer variability. Although deep learning models achieved high segmentation accuracy, performance improvements were often accompanied by increased computational complexity, limiting their applicability in resource-constrained clinical environments. To address this issue, an efficiency-oriented segmentation framework was developed based on a lightweight three-dimensional U-Net enhanced with a shallow Transformer module and guided by knowledge distillation. The main contribution of this study was the integration of logit-level and feature-level distillation to improve segmentation capability while maintaining low inference complexity. The framework emphasized a balanced trade-off between segmentation accuracy and computational efficiency rather than benchmark maximization. Experiments were conducted using the BraTS 2020 and BraTS 2021 datasets. The official training sets were internally split into eighty percent for training and twenty percent for validation. The student network was trained using a hybrid segmentation loss combined with temperature-scaled logit distillation and bottleneck feature alignment from a higher-capacity teacher model. Model performance was evaluated using Dice score, Intersection over Union, and computational complexity measured in floating-point operations. On the BraTS 2021 dataset, the proposed model achieved Dice scores of 0.6538 for Whole Tumor, 0.5382 for Tumor Core, and 0.5304 for Enhancing Tumor. Per-class Dice values were 0.9706 for background, 0.3028 for necrotic or non-enhancing tumor core, 0.4938 for edema, and 0.4936 for enhancing tumor. The corresponding Intersection over Union values followed similar trends. The model maintained an inference complexity of approximately 54.38 gigafloating-point operations for input patches of size 64 × 64 × 64. These findings indicated that the proposed framework achieved a stable balance between segmentation performance and computational efficiency, supporting practical deployment under limited computational resources

Abstract

The application of Artificial Intelligence (AI) in mental health is experiencing rapid development, while algorithmic transparency and clinical translation readiness still face fundamental obstacles. This review synthesizes empirical findings related to the use of Explainable Artificial Intelligence (XAI) in mental health and biomedical decision systems, focusing on three evaluative aspects, namely explainability architecture, validation strength, and clinical integration. The literature search followed the PRISMA 2020 guidelines across five major databases for publications from 2020 to 2026 and yielded nine studies that met the inclusion criteria. The synthesis results show the dominance of post-hoc approaches, particularly SHAP, which are commonly applied to ensemble and boosting models, while intrinsic models and counterfactual approaches are still rarely used. The majority of studies rely on internal validation, while independent external validation and prospective application in real clinical workflows are relatively limited. User-based evaluation of explainability has also been understudied, with algorithmic transparency more often understood as technical feature attribution rather than as a verified mechanism in clinical decision-making. These findings indicate a persistent gap between methodological advances and the level of clinical translation maturity. Explainability has not been systematically integrated with robust validation designs or user-oriented evaluations. This review proposes a translation evaluation framework that combines technical and clinical dimensions to assess the readiness for XAI implementation more comprehensively. The development of XAI in mental health requires evaluation standardization, strengthened external validation, and prospective testing focused on clinical impact and user trust.

Abstract

The rapid expansion of digital health technologies has significantly transformed the delivery of community-based nursing services. Telehealth informatics has increasingly been adopted to enhance access, continuity, and quality of care, particularly in chronic disease management and home-based services. However, implementation approaches vary across health systems, and the relationship between implementation strategies and quality outcomes remains insufficiently synthesized. This study aimed to identify telehealth informatics implementation strategies in community nursing, analyze their impact on quality outcomes, and explore barriers and facilitators influencing adoption. A systematic literature review was conducted in accordance with PRISMA guidelines. Searches were performed in Scopus, ScienceDirect, PubMed, and CINAHL for studies published between 2022 and 2026. Eligible studies focused on telehealth interventions implemented in community or home care nursing contexts and reported measurable quality outcomes. Fifteen international studies met the inclusion criteria and were analyzed using a descriptive-comparative thematic synthesis. The findings indicate that successful telehealth implementation is associated with interoperable digital infrastructure, structured workflow integration, managerial support, digital competency development, and regulatory alignment. Quality improvements were observed across multiple domains, including reduced hospital admissions, improved disease-specific clinical indicators, enhanced patient satisfaction, and favorable cost-effectiveness estimates. Nevertheless, variability in long-term sustainability and readmission outcomes was noted. Key barriers included limited interoperability, digital literacy gaps, reimbursement constraints, and regulatory ambiguity, whereas structured training, organizational readiness, and interdisciplinary collaboration facilitated adoption. It is concluded that telehealth informatics has substantial potential to enhance quality of care in community nursing when implemented through systematic, competency-based, and policy-supported strategies. Sustainable integration requires coordinated investment in digital infrastructure, workforce preparedness, and governance frameworks that promote equitable and effective community care delivery.
