While State Space Models (SSMs) scale linearly with sequence length, adapting them to 2D vision often increases architectural complexity without commensurate benefit for non-autoregressive tasks. We introduce MambaOutRS, a hybrid convolutional architecture that combines Gated CNN blocks for local spatial modeling with a Fourier Filter Gate (FFG) for efficient global context extraction in the frequency domain. Evaluated on UC Merced, AID, EuroSAT, and NWPU-RESISC45, MambaOutRS achieves state-of-the-art or competitive performance while maintaining a favorable parameter budget. Ablation studies confirm that the FFG is the primary driver of performance improvement, enabling the model to capture global spatial patterns that are inaccessible to purely local convolutional operations. This work demonstrates that combining gated convolutions with frequency-domain filtering provides a highly efficient and practical alternative to recurrent SSM-based designs for remote sensing image classification.

Artificial intelligence (AI) is rapidly transforming language education. However, its pedagogical and sociocultural impacts on Japanese business writing remain underexplored. This study aims to examine how ChatGPT4o-based automated feedback functions within Japanese business writing education for adult learners in online higher education, with particular attention to both its instructional impact and learners’ sociocultural awareness. Situated in a cyber university context where the proportion of adult learners is increasing, the study explores the potential of AI-mediated feedback to address learners’ diverse educational and cultural needs. It employed a mixed-methods design, combining a survey of 27 participants and in-depth interviews with 11 participants. The interviews were transcribed and thematically coded to gain deeper insights into learners’ perceptions. The findings indicate that ChatGPT feedback contributed to learners’ planning of study strategies, the provision of immediate and personalized corrections, the reinforcement of error awareness, and the acquisition of honorific and polite expressions. On the one hand, learners reported that they could quickly understand regional language practices and communication conventions in business contexts, thereby deepening their cultural sensitivity. On the other hand, some learners expressed concern that increased reliance on AI could weaken exploratory and critical learning. These results suggest that ChatGPT can serve not merely as a correction tool but also as an educational resource that simultaneously fosters self-directed learning and sociocultural competence. However, to ensure reliability and cultural appropriateness, hybrid feedback incorporating instructor guidance is necessary. This study has academic significance in demonstrating the potential of extending AI-based feedback to Japanese business communication education, thereby constructing an integrated language and culture learning environment.

South Korea’s Act on the Safety of and Support for Advanced Regenerative Medicine and Advanced Biological Products, enacted in 2019, was recently amended. This article examines the new advanced regenerative medicine treatment (ARMT) category, focusing on patient access, review processes, safety monitoring, ethical safeguards, and lessons from Japan’s comparable framework.

This study analyzed data from the Military Health and Well-being Project (MHWBP) to examine the influence of combat exposure on suicidal behavior among U.S. military personnel with combat experience, focusing on the moderated effects of moral injury and stigma. Data from 1,495 service members were analyzed, revealing significant correlations among the variables. The Process Macro was employed to assess the impact of moral injury and stigma on suicidal behavior. Furthermore, moderated moderation analyses were conducted, revealing that combat experience had a stronger relationship on suicidal behavior among individuals with high levels of moral injury and stigma. These findings shed light on the interacting factors through which combat exposure affects suicidal behavior among military personnel and are discussed in terms of their implications, limitations, and future research directions.
