The apparatus may comprise, a controller and memory storing instructions, when executed by the controller, configured to cause the apparatus to, receive global positioning system (GPS) information, High Definition (HD) map information, road information, and sensor information, wherein the GPS information, the HD map information, and the road information are related to one or more roads ahead of the vehicle, generate, based on the GPS information, the HD map information, road information, and the sensor information, road change information, wherein the road change information is related to whether a driving road which the vehicle travels on is changed to or from a road, and wherein the road is associated with a preset class, and output, based on the road change information, a signal for controlling the autonomous driving of the vehicle.

Abstract: An autonomous driving control method receives a HD map and extracts a HD road boundary and a HD lane line based on the HD map. A real-time map displaying a road driving environment of a vehicle is generated using sensor information detected by a sensor mounted on the vehicle. A real-time road boundary and a real-time lane are extracted based on the generated real-time map. The HD road boundary is compared to and analyzed from the real-time road boundary, and the HD lane line is compared and analyzed to the real-time lane. It is determined whether the HD map has changed based on the analyzed result value.

Abstract: A method for isolating and culturing umbilical cord blood stem cells that express high levels of GDF-3 is disclosed. Umbilical cord blood stem cells isolated and cultured as described herein exhibit high expression of GDF-3. Stem cells with high expression of GDF-3 maintain high proliferation capacity contrary to conventional stem cells even as passages progress, allowing for the advantage of obtaining a large quantity of healthy stem cells. Furthermore, due to the higher proliferation rate of stem cells, it has been observed that the concentration of extracellular matrix components secreted by the cells is also higher. Therefore, when utilizing GDF-3 high-expressing umbilical cord blood stem cells for the production of cell and culture medium compositions, it is possible to produce raw materials with excellent efficacy and effects.

Abstract: The present invention relates to a method for preparing a culture medium containing exosomes released by umbilical cord blood stem cells. The preparation method is based on culturing the umbilical cord blood stem cells in a serum-free medium supplemented with GDF-11, EGF, FGF2, TFG-?1, and/or VEGF. The culture medium produced by treating umbilical cord blood stem cells with a serum-free medium supplemented with 5 types of growth factors and the exosomes isolated from the culture medium has a higher total protein content and extracellular matrix protein content, when compared to a culture medium produced by culturing umbilical cord blood stem cells in a serum-free medium to which the growth factor is not added. In addition, exosomes released by umbilical cord blood stem cells cultured in a serum-free medium containing five growth factors have a high concentration, a small size, and an even distribution.
