Abstract: Embodiments relate to a polymer film. The polymer film comprises a polymer resin selected from the group consisting of a polyamide-based resin and a polyimide-based resin and has a haze (HZ0) before autoclave treatment of 3% or less and a ?HZ24 represented by Equation 1a of 500% or less.

Abstract: An image encoding/decoding method is provided. An image decoding method of the present invention may comprise deriving an intra-prediction mode of a current luma block, deriving an intra-prediction mode of a current chroma block based on the intra-prediction mode of the current luma block, generating a prediction block of the current chroma block based on the intra-prediction mode of the current chroma block, and the deriving of an intra-prediction mode of a current chroma block may comprise determining whether or not CCLM (Cross-Component Linear Mode) can be performed for the current chroma block.

Abstract: A container loading and unloading apparatus including a container support frame at a base of a container main body and including a reception frame and a traverse frame; an inverted L-shaped container supporter in the traverse frame and including a horizontal adjustable supporter, a vertical supporter and a vertical adjustable supporter; covers formed at upper and lower ends of the vertical supporter and the vertical adjustable supporter, respectively; hanger fittings fixedly mounted in the covers for hanging a coil spring; a fixing device provided at a side surface of the traverse frame for fixing the container supporter; a reception groove formed on an outer side of the reception frame receiving the container supporter; elevation devices provided in a chassis of a freight car, each including a hydraulic cylinder operating in a vertically upward direction; and a guidance arrangement positioned corresponding to each elevation device.

Abstract: Disclosed is a container loading and unloading apparatus, which overcomes a problem of a conventional container in that a special equipment such as a forklift truck, a crane or the like is necessarily mobilized whenever the loading or unloading work is performed because the container is simply a cuboidal rigid body. The present invention makes it possible to perform the loading and unloading works of the container main body at the time of its storage and transportation without a separate loading and unloading equipment by providing a container supporter to secure a space for loading the container main body on a chassis of a freight car, thereby reducing equipments and labor as well as facilitating the loading and unloading works.
