Abstract: Disclosed is a method of providing driving information of an autonomous vehicle performed by an apparatus that includes a first sensor unit, a second sensor unit, a processor, and a projection unit. The method includes: acquiring, by the first sensor unit, surroundings information of the autonomous vehicle; acquiring, by the second sensor unit, information on an occupant on board the autonomous vehicle; generating, by the processor, main driving information from the surroundings information of the autonomous vehicle acquired by the first sensor unit; determining, by the processor, the main driving information to be provided to the occupant from among the main driving information based on the information on the occupant; and providing, by the projection unit, the main driving information determined by the processor to the occupant of the autonomous vehicle.

Abstract: A computer implemented method and apparatus provide a route to postpone or delay arrival of a vehicle at a destination. The method includes: obtaining, by a processor, behavior information indicating a behavior of an occupant in the vehicle; receiving, by the processor from the occupant, time information for postponing arrival of the vehicle at the destination; and providing, by the processor, at least one recommended route according to the behavior information and the time information.

Abstract: The present disclosure relates to a portable printer including a main body in a portable form which is capable of accommodating a cartridge having a nozzle for delivering a printing material to a target having a soft or hard surface, a seating part which is provided to be exposed to an outside from a lower portion of the main body to face the surface of the target and at least partially surrounds the nozzle, a roller provided respectively at the front and rear of the nozzle at the lower portion of the main body with respect to a direction in which the main body moves along the surface of the target to deliver the printing material to the target, and a printing adjustment unit configured to adjust a height difference between the nozzle and the roller to adjust a height difference between the nozzle and the surface of the target.

Abstract: Proposed is an all-solid-state battery including a self-standing sheet layer positioned on a negative electrode current collector. The all-solid-state battery may include the negative electrode current collector, the self-standing sheet layer positioned on the negative electrode current collector, a solid electrolyte layer positioned on the sheet layer, a positive electrode active material layer positioned on the solid electrolyte layer, and a positive electrode current collector positioned on the positive electrode active material layer. The sheet layer contains carbon nanotubes.

Abstract: Provided are a method for removing and/or absorbing greenhouse gases using aquatic plant and/or algae having a greenhouse gas absorbing performance and resistance to toxic substances, a method for producing bioenergy using predators with high fatty acids, and a method for producing bioenergy including cultivating aquatic plant and/or algae having a greenhouse gas absorbing performance and resistance to toxic substances, while supplying a waste gas mixture to the aquatic plant and/or algae, (S2) cultivating predators having a capability to prey on the aquatic plant and/or algae while supplying the aquatic plant and/or algae to the predators, (S3) harvesting the predators, and (S4) converting the harvested predators into bioenergy.
