Abstract: There is provided a method for providing driver's driving information of a user terminal device, including accessing a driving information providing server storing data generated in a driving recording device for a vehicle, receiving driving record data including event record data corresponding to a driving-related event of a driver from the driving information providing server, and displaying a driving-related event occurrence location on a map using the received driving record data. The driving-related event may include at least two or more of a lane departure event, a forward collision possibility event, a rear side collision possibility event, a sudden deceleration event, a sudden acceleration event, a sudden stop event, a sudden start event, and a speeding event.

Abstract: An etching apparatus includes a receiving container which receives a substrate, and a first spraying unit which supplies etchant into the receiving container. The receiving container includes a bottom plate, a plurality of bottom through holes defined in the bottom plate and through which the etchant is drained from the receiving container; and a plurality of side walls extended from the bottom plate.

Abstract: An injection system for cold start improvement of a flexible-fuel vehicle (FFV), may include a first injector installed in an intake port, and a second injector installed in the intake port in which the first injector may be installed and having a built-in heater, wherein the first injector and the second injector may be positioned upstream of intake valves.

Abstract: A rotary input apparatus is disclosed. A rotary input apparatus that includes a wheel which inputs information by rotation; a holder which rotatably supports the wheel; a tooth or teeth formed on any one of the wheel and the holder; and a flat spring which is supported by the other of the wheel and the holder and which catches onto the tooth to elastically support the wheel in the direction of rotation, utilizes a simple structure to allow smooth operation while implementing a clicking sensation for each section.

Abstract: Provided is a method for treating depression with a Nelumbinis Semen extract. The Nelumbinis Semen extract is prepared by extracting Nelumbinis Semen with an alcohol or an alcohol solution. The Nelumbinis Semen extract has been demonstrated using animal behavioral, bio-chemical and molecular biological methods to have strong antidepressive activity, as well as inhibiting immune suppression caused by depression, leading to normal immune responses, and reducing side effects of conventional antidepressants, thereby ensuring safety. Thus, the Nelumbinis Semen extract is useful for preparing a composition or health food for treating depression.

Abstract: There is provided a rotary input apparatus including: a rotating wheel having a detected part; a board provided with a detecting part detecting the detected part rotating along with the rotating wheel; a base having the board disposed on a top thereof and provided with a plurality of guide holes therein; and a holder having the rotating wheel rotatably assembled therewith, and provided with a plurality of guide protrusions inserted through the guide holes to be exposed to a bottom of the base and having lower ends thereof stuck into the guide holes, respectively, the holder disposed between the rotating wheel and the board. The apparatus, when assembled in an assembly line, experiences minimum interference with other members, thereby enhancing work efficiency and ensuring more freedom in design.

Abstract: The present invention relates to an Nelumbinis semen extract having the effect of preventing or treating ischemic heart disease, as well as a pharmaceutical composition and health food for the prevention or treatment of ischemic heart diseases, which contain the Nelumbinis semen extract.
