Abstract: A battery module includes a module housing, a gauge hole formed in the module housing, a plurality of battery cells in the module housing, a cell pressing plate accommodated in the module housing, and a swelling gauge provided to protrude from a surface of the cell pressing plate. The plurality of battery cells have a normal state and a swelling state. An end of the swelling gauge extends outside the module housing when the plurality of battery cells are in the normal state.

Abstract: A pouch type secondary battery in which an electrode lead of the pouch type secondary battery and an electrode lead of an adjacent different pouch type secondary battery are welded together to construct a battery module is provided. The electrode lead of the pouch type secondary battery includes a length extended part so that, after cutting a welded part of the electrode leads of the pouch type secondary battery and the adjacent different pouch type secondary battery to form electrode leads of remaining length, the electrode leads of remaining length are welded together again. A battery module and method of reusing the battery module are also provided.

Abstract: A battery module housing includes a receiving portion configured to allow a battery cell stack to be mounted therein. The receiving portion comprises a first side surface and a second side surface, a bolting portion configured to couple a plurality of battery module housings disposed adjacent to each other, and a buffer portion configured to absorb volume expansion of the battery cell stack, whereby a battery pack capable of accommodating an increase in volume of the battery cell stack while having reduced weight and minimized construction is provided.

Abstract: According to one embodiment of the present invention, there is provided a method for setting a customized tooth color, comprising: a first step of generating a patient's tooth color data; a second step of setting tooth color data for each section of artificial tooth based on the patient's tooth color data; a third step of performing an aesthetic prediction display based on the tooth color data for each section of artificial tooth, and correcting errors by comparing the artificial tooth displayed by the aesthetic prediction display with the patient's tooth color data; and a fourth step of determining artificial tooth color data by reflecting error correction.

Abstract: The present invention relates to a composition for oral application and a method for preparing the same, more particularly, to a composition for oral application comprising a complex of specific Lewis base and specific Lewis acid, and a method for preparing the same. The composition for oral application of the present invention has excellent durability, body stability and coatibility, and thus, can effectively treat dentin hypersensitivity, and when applied before dentin hypersensitivity occurs, can prevent dentin hypersensitivity.
