Abstract: A stringed instrument, such as a violin, viola, cello, or double bass, having an inherently flat back and an inherently flat top separated by a rib structure. An interior soundpost spans between the back and the top. A bridge supports the strings over the top. When tension is applied in the strings such that the bridge applies force to the top and the soundpost applies force to the back, the top acquires a concave shape and the back acquires a convex shape. In a particular embodiment, the instrument has retaining rings mounted on interior surfaces of the back and top keep the soundpost from falling over, two subassemblies interconnected by an adjustable screw-and-nut arrangement to achieve different string heights, a nut opening configured to receive differently sized top nuts for different string heights, and an inherently straight bass bar, where the bridge has feet having inherently collinear bottoms.

Abstract: The present invention provides a novel aminoaromatic compound or a pharmaceutically acceptable salt thereof, a pharmaceutical composition that is for preventing or treating neurodegenerative diseases and comprises same as an active ingredient, and a health functional food composition for preventing or ameliorating neurodegenerative diseases.

Abstract: A packable chair is provided that is transformable between multiple configurations, including a chair configuration where a user can sit, recline, or lay in the chair, and a collapsed configuration in which the chair can be carried, pulled, or worn as a backpack for convenient transportation. The packable chair is capable of a storage configuration in which the portions of the packable chair are arranged and fastened to define an enclosed volume. A user can wear the packable chair like a backpack in this storage configuration to transport contents.

Abstract: A packable chair is provided that is transformable between multiple configurations, including a storage configuration and a chair configuration. In the storage configuration, the portions of the packable chair are arranged and fastened to define an enclosed volume in which containers and other items can be stored. A user can wear the packable chair like a backpack in this storage configuration to transport the contents from, for example, a car to a location on a beach. Then, the contents can be removed from the enclosed volume, and the portions can be rearranged to form the chair configuration where a user can lounge and access the contents of the containers. The chair is also capable of achieving a travel configuration in which the chair can be worn as a backpack for convenient transportation without stowing a user's items.
