Despite significant developments in 3D multi-view multi-person (3D MM) tracking, current frameworks separately target footprint tracking, or pose tracking. Frameworks designed for the former cannot be used for the latter, because they directly obtain 3D positions on the ground plane via a homography projection, which is inapplicable to 3D poses above the ground. In contrast, frameworks designed for pose tracking generally isolate multi-view and multi-frame associations and may not be sufficiently robust for footprint tracking, which utilizes fewer key points than pose tracking, weakening multi-view association cues in a single frame. This study presents a unified multi-view multi-person tracking framework to bridge the gap between footprint tracking and pose tracking. Without additional modifications, the framework can adopt monocular 2D bounding boxes and 2D poses as its input to produce robust 3D trajectories for multiple persons. Importantly, multi-frame and multi-view information are jointly employed to improve association and triangulation. Our framework is shown to provide state-of-the-art performance on the Campus and Shelf datasets for 3D pose tracking, with comparable results on the WILDTRACK and MMPTRACK datasets for 3D footprint tracking.

Pt/CeO2–ZrO2–SnO2/γ-Al2O3 catalysts were prepared by co-precipitation and wet impregnation methods for catalytic oxidation of acetaldehyde to acetic acid in water. In the present catalysts, Pt and CeO2–ZrO2–SnO2 were successfully dispersed on the γ-Al2O3 *** of platinum content and reaction time on the selective oxidation of acetaldehyde to acetic acid were investigated to optimize the reaction conditions for obtaining both high acetaldehyde conversion and highest selectivity to acetic acid. Among the catalysts, a Pt（6.4 wt.%）/Ce0.68Zr0.17Sn0.15O2.0（16 wt.%）/γ-Al2O3 catalyst showed the highest acetaldehyde oxidation activity. On this catalyst, acetaldehyde was completely oxidized after the reaction at 0°C for 8 hr, and the selectivity to acetic acid reached to 95%and higher after the reaction for 4 hr and longer.

Purpose: The objective of the present study was to identify the type of experiences that parents and their children have with each other when late-school age children take on roles in family routines related to daily meals. Methods: A grounded theory approach was used. The participants were children in the 4th, 5th, and 6th grades of elementary school and their main caregivers. First, 10 parent and child dyads were interviewed using a semi-structured schedule. Next, online group interviews were conducted for 17 parent and child dyads to deductively confirm the categories. Results: The average age of the subjects was 41.9 years for parents and 10.4 years for children in parent-child interviews, and 41.1 years for parents and 9.6 years for children in group interviews. Six categories emerged with nineteen subcategories. Conclusions: Experiences mutually nurtured by parents and their children included experiences in which children used negotiation and conversation skills to consensually engage in family routines related to meals. It also included experiences that socialized the children in family life and fostered good communication. The six categories will be useful for healthcare professionals and school authorities in providing health guidance that addresses health functions of late school-age children and their families.
