Abstract: The present invention relates to substituted pyrrolidinone compounds of formula 1, wherein n is 0 or 1; Aza is a heterocycle optionally substituted with C1-4 alkyl, or C1-4 alkyl substituted with a heterocycle, which represents a saturated or unsaturated five- or six-membered ring having nitrogen(s) as a heteroatom, which are muscarinic acetylcholine receptor agonists and useful as nootropics and therapeutic agents for cerebral neural diseases such as Alzheimer's disease; and pharmaceutically acceptable salts thereof; processes for the preparation thereof; and pharmaceutical compositions comprising these compounds or salts.

Abstract: The present invention relates to novel tetrahydropyridine derivatives of formula 1 having an appropriately substituted pyrrolidinone and oxime, wherein m is 0 or 1, n is 1 or 2, R1 is hydrogen, C1-4alkyl, C2-4 alkynyl or aryl, R3 is C1-4 alkyl, which show high efficacy, low cholinergic adverse effects and high affinity for muscarinic acetylcholine receptor; and pharmaceutically acceptable salts thereof; processes for the preparation thereof; and pharmaceutical compositions comprising these compounds or salts.

Abstract: Disclosed is a method of managing an image display apparatus of the present invention. The method includes the steps of: (a) obtaining a first information on a predetermined output image format; (b) obtaining a second information on an input image format and a data broadcasting contents format; (c) comparing the first information on the predetermined output image format with the second information on the input image format and the data broadcasting contents format; (d) controlling output modes of the input image format and the data broadcasting contents format according to the predetermined output image format based on a comparison result of the output image format, the input image and the data broadcasting contents format performed by the comparing unit; and (e) outputting on image display unit the input image and the data broadcasting contents output modes of which are processed.
