Abstract: Disclosed herein are novel 1,3-dihydro-5-isobenzofurancarbonitrile derivatives represented by Formula 1, or pharmaceutically acceptable salts thereof. Also disclosed is a pharmaceutical composition for treating or preventing premature ejaculation including the compound. The 1,3-dihydro-5-isobenzofurancarbonitrile derivatives have a short half-life and inhibit the ejaculation process by selectively inhibiting serotonin reuptake via a serotonin reuptake transporter present in a presynaptic neuron. Thus, the compounds are useful in the treatment and prevention of premature ejaculation.

Abstract: An information processing apparatus includes a casing having a first accommodating unit, and a second accommodating unit which protrudes from at least one area of the first accommodating unit; a main body which includes at least one heat generating component which is accommodated in the first accommodating unit, and a port unit which is formed at an outer side of the first accommodating unit; and a heat radiating unit which is accommodated in the second accommodating unit, and discharges heat of the heat generating component to an outside of the casing.

Abstract: The present invention relates to an apparatus and process for oxygen concentration that makes possible the production of highly purified concentrated oxygen by modifying the structure of the adsorption bed and with various valves coupled thereto, and which can increase purity of the oxygen produced and reduce mechanical energy and consumption of electricity of the air compressor.

Abstract: The present invention provides a 3?,4?,5-trimethoxy flavone derivative and a pharmaceutically acceptable salt thereof, preparation thereof, and a pharmaceutical composition for the treatment and prevention of dry eye syndrome comprising the same as an active ingredient. The 3?,4?,5-trimethoxy flavone derivative and its pharmaceutically acceptable salt inhibit corneal damage through excellent stimulatory action on mucus secretion in the conjunctiva and therefore may be effective as a prophylactic or therapeutic agent for dry eye syndrome.

Abstract: A portable computer and a method of controlling the same that can secure safety of circuit and system by interrupting or providing an output of power and/or image signal supplied to a display panel in accordance with results of sensing an operation of a locking unit.
