In this paper, we propose a two-stage multi-modal future trajectory prediction framework designed to effectively utilize significant inter-agent interaction and local scene context. This two-stage motion prediction architecture, referred to as GL-Pred, consists of two networks: the proposal trajectory network and the refinement trajectory network. The proposal trajectory network produces multi-modal trajectory proposals by leveraging past trajectories and global environmental information. The refinement trajectory network enhances each of the trajectory proposals using group-query attention and localquery attention mechanisms. Group-query attention mechanism further enhances the trajectory proposals by modeling the interagent interaction by grouping the proposal trajectory of the neighboring agents. Local-query attention mechanism is used to aggregate local scene context features collected from around trajectory proposals. Finally, we combine group-query attention and local-query attention features to produce the multi-modal future trajectory. The experiments conducted on the Argoverse dataset demonstrate that the proposed GL-Pred outperforms existing motion prediction methods.

Background and Objectives: In this study, we investigated the effects of hearing loss on mental health and quality of life (QoL) using survey data in adults aged >40 years.Subjects and Methods: We obtained data from 10,921 individuals who responded to the fifth Korean National Health and Nutrition Examination Survey. Primary outcomes were measured using questionnaires that recorded stress perception, depressive mood, and suicidal ideation to evaluate mental health and motor ability, self-management, activities of daily living, pain or discomfort, and anxiety or depression to evaluate QoL.Results: On multivariate analysis, suicidal ideation was more prevalent among older adults with hearing loss than in older adults without hearing loss. Motor ability was lower in individuals with hearing loss of >20 dB than in older adults with normal hearing. Categorization of the EuroQol-5 Dimension (EQ-5D) health state into upper and lower groups showed that the EQ-5D values were lower in the moderate-tosevere hearing loss group than in the mild hearing loss group.Conclusions: Among adults aged >40 years, those with hearing loss experienced more suicidal ideation, had lower motor ability, and lower overall QoL compared with these variables in older adults with normal hearing. Additionally, QoL scores were low in individuals with poor hearing.
