Beyond technical accuracy, this work explicitly addresses the trustworthy AI Knowledge for precision agriculture through transparent data sourcing by standardized indices, model explainability by using established U-Net++ architectures, and validation against known flood-impact scenarios. Organizational integration is facilitated by generating diagnostic knowledge directly usable by farmers and agricultural extension services in vulnerable ecosystems like Majuli, enabling timely interventions for improved resilience and yield.

Nurses, as primary healthcare providers, play a pivotal role in addressing these disparities; however, nursing education frequently lacks adequate training to prepare students for the unique needs of LGBTQIA+ patients. This study aimed to assess the perceptions, confidence, and institutional training of nursing students in India regarding LGBTQIA+-inclusive care. A quantitative, descriptive survey design was employed, involving 90 nursing students who completed a 16 item structured and validated questionnaire. Results revealed that while students exhibited positive perceptions toward LGBTQIA+ individuals, their confidence in performing critical tasks, such as sexual history-taking and physical examinations, was low. Institutional training was also found to be insufficient, indicating gaps in the current curriculum.
