Integrated In-vehicle Monitoring System Using 3D Human Pose Estimation and Seat Belt Segmentation
Recently, along with interest in autonomous vehicles, the importance of
monitoring systems for both drivers and passengers inside vehicles has been
increasing. This paper proposes a novel in-vehicle monitoring system the
combines 3D pose estimation, seat-belt segmentation, and seat-belt status
classification networks. Our system outputs various information necessary for
monitoring by accurately considering the data characteristics of the in-vehicle
environment. Specifically, the proposed 3D pose estimation directly estimates
the absolute coordinates of keypoints for a driver and passengers, and the
proposed seat-belt segmentation is implemented by applying a structure based on
the feature pyramid. In addition, we propose a classification task to
distinguish between normal and abnormal states of wearing a seat belt using
results that combine 3D pose estimation with seat-belt segmentation. These
tasks can be learned simultaneously and operate in real-time. Our method was
evaluated on a private dataset we newly created and annotated. The experimental
results show that our method has significantly high performance that can be
applied directly to real in-vehicle monitoring systems.Comment: AAAI 2022 workshop AI for Transportation accepte
Individual Pulmonary Vein Atresia in Adults: Report of Two Cases
We present two cases of individual pulmonary vein atresia without vestige of an involved pulmonary vein. On CT, we noted the absence or interruption of normal pulmonary venous structures, and the presence of abnormal vascular structures that represented collaterals for the involved lung parenchyma. On angiography, the atretic pulmonary vein was found to drain into the other ipsilateral pulmonary veins through the collaterals
Prevalence and predictors of heated tobacco products use among male ever smokers: results from a Korean longitudinal study
Background
This study examined sociodemographic and tobacco-related factors of heated tobacco products (HTPs) use among adult ever smokers in South Korea where the sales of HTPs have been rapidly increasing since their launch in June 2017.
Methods
Before the launch of HTPs in Korea, participants comprised male ever smokers (234 current smokers and 37 quitters) who participated in the Korea National Health and Nutrition Examination Survey from 2015 to 2017 through one-to-one interview survey and agreed to participate in the follow-up surveys through telephone in December 2017. Data were analyzed using logistic regression, to explore sociodemographic and smoking behavior-related factors of HTPs use.
Results
Overall, 10.7% (29/271) of participants responded to using HTPs and 8.1% (22/271) were current HTPs users at the time of the follow-up survey. Multivariate analysis showed that HTPs use is associated with middle age (36 to 49 years old) (aOR = 3.72, CI = 1.16–12.0) (vs. ≥ 50 years), higher income (4Q vs 1Q: aOR = 2.71, CI = 1.16–6.34), and higher educational level (college or higher: aOR = 2.40, CI = 0.87–6.60). Also, vaping experience at baseline was highly associated with HTPs use (aOR = 3.11, CI = 1.22–7.93 for the former experience; aOR = 9.14, CI = 2.34–35.6 for current). However, smoking amount and level of motivation for smoking cessation were not found to be predictors of future HTPs use when limited to current smokers at baseline.
Conclusions
The results showed that vaping experience regardless of current smoking behavior and higher socioeconomic status were found to be associated with subsequent HTPs use among ever smokers. Further studies are required to explore whether this association is causal.This work was supported by the Korea Centers for Disease Control and Prevention (grant numbers 2017-E34011–00).

Lightweight Monocular Depth Estimation via Token-Sharing Transformer
Depth estimation is an important task in various robotics systems and
applications. In mobile robotics systems, monocular depth estimation is
desirable since a single RGB camera can be deployable at a low cost and compact
size. Due to its significant and growing needs, many lightweight monocular
depth estimation networks have been proposed for mobile robotics systems. While
most lightweight monocular depth estimation methods have been developed using
convolution neural networks, the Transformer has been gradually utilized in
monocular depth estimation recently. However, massive parameters and large
computational costs in the Transformer disturb the deployment to embedded
devices. In this paper, we present a Token-Sharing Transformer (TST), an
architecture using the Transformer for monocular depth estimation, optimized
especially in embedded devices. The proposed TST utilizes global token sharing,
which enables the model to obtain an accurate depth prediction with high
throughput in embedded devices. Experimental results show that TST outperforms
the existing lightweight monocular depth estimation methods. On the NYU Depth
v2 dataset, TST can deliver depth maps up to 63.4 FPS in NVIDIA Jetson nano and
142.6 FPS in NVIDIA Jetson TX2, with lower errors than the existing methods.
Furthermore, TST achieves real-time depth estimation of high-resolution images
on Jetson TX2 with competitive results.Comment: ICRA 202
Immunogenicity and Vaccine Potential of InsB, an ESAT-6-Like Antigen Identified in the Highly Virulent Mycobacterium tuberculosis Beijing K Strain
Our group recently identified InsB, an ESAT-6-like antigen belonging to the Mtb9.9 subfamily within the Esx family, in the Mycobacterium tuberculosis Korean Beijing strain (Mtb K) via a comparative genomic analysis with that of the reference Mtb H37Rv and characterized its immunogenicity and its induced immune response in patients with tuberculosis (TB). However, the vaccine potential of InsB has not been fully elucidated. In the present study, InsB was evaluated as a subunit vaccine in comparison with the most well-known ESAT-6 against the hypervirulent Mtb K. Mice immunized with InsB/MPL-DDA exhibited an antigen-specific IFN-γ response along with antigen-specific effector/memory T cell expansion in the lungs and spleen upon antigen restimulation. In addition, InsB immunization markedly induced multifunctional Th1-type CD4+ T cells coexpressing TNF-α, IL-2, and IFN-γ in the lungs following Mtb K challenge. Finally, we found that InsB immunization conferred long-term protection against Mtb K comparable to that conferred by ESAT-6 immunization, as evidenced by a similar level of CFU reduction in the lung and spleen and reduced lung inflammation. These results suggest that InsB may be an excellent vaccine antigen component for developing a multiantigenic Mtb subunit vaccine by generating Th1-biased memory T cells with a multifunctional capacity and may confer durable protection against the highly virulent Mtb K
