Enhancing LiDAR Mapping with YOLO-Based Potential Dynamic Object Removal in Autonomous Driving.

In this study, we propose an enhanced LiDAR-based mapping and localization system that utilizes a camera-based YOLO (You Only Look Once) algorithm to detect and remove dynamic objects, such as vehicles, from the mapping process. GPS, while commonly used for localization, often fails in urban environments due to signal blockages. To address this limitation, our system integrates YOLOv4 with LiDAR, enabling the removal of dynamic objects to improve map accuracy and localization in high-traffic areas.

Growth promotion effect of red ginseng dietary fiber to probiotics and transcriptome analysis of .

Background: Red ginseng marc, the residue of red ginseng left after water extraction, is rich in dietary fiber. Dietary fiber derived from fruits or vegetables can promote the proliferation of probiotics, and it is a key technology in the food industry to increase the productivity of probiotics by adding growth-enhancing substances such as dietary fiber. In this study, the effect of red ginseng dietary fiber (RGDF) on the growth of probiotic bacterial strains was investigated at the phenotypic and genetic levels.

Safety assessment of IDCC 2201 used for product manufacturing in Korea.

Safety evaluation of probiotics has become increasingly important for human consumption in food industry. The aims of this study were to assess safety of IDCC 2201 through in vitro and in vivo tests. In results, this strain was found to be negative for hemolytic and β-glucuronidase activity.
