    Abstract: The present invention is directed to a method for producing DME, which comprises separating a CO 2 rich stream from a crude product stream containing DME and CO 2 obtained by a DME synthesis from a feed syn gas; introducing the CO 2 rich stream to a reverse water gas shift (RWGS) reactor wherein it is reacted with hydrogen in the presence of a catalyst to provide a CO rich stream, and recycling the CO rich stream to the step of the methanol synthesis step. In accordance with the present invention, a large amount of carbon dioxide gas generated during the preparing process of DME is effectively re-used, thus increasing the yield of DME and lowering the amount of carbon dioxide discharged.

    Abstract: The present invention relates to a method of designing peripheral equipment for molecular modeling system on a computer. In more detail, it relates to a method of designing peripheral equipment that provides intuitive input/output devices to a molecular modeling system so that a user can display a molecule on a computer and comprehend various characteristics of the molecule at once. By separating the screens corresponding to left/right eyes respectively, the present invention makes it possible to output a stereo-view of a molecule. In addition, for assisting a user to easily handle two or more molecules on a computer, the present invention provides gloves, a spatial location tracking instrument, and a force feedback joystick, which transfers the interaction force between two molecules to the user, as input devices in addition to the conventional computer input devices, a keyboard and a mouse.

    Abstract: The present invention relates to an anticancer drug-chitosan complex forming self-aggregates and the preparation method thereof. More precisely, the present invention relates to the anticancer drug-chitosan complex forming self-aggregates in aqueous media composed of a hydrophobic anticancer agent and a hydrophilic chitosan, and the preparation method thereof. The anticancer drug-chitosan complex of the present invention not only works selectively against target tumor tissue but also continues to release the medicine over a long period of time. Besides, the anticancer drug-chitosan complex could have greater amount of drug by adding the anticancer drug into self-aggregates, which is generally limited by chemical bond. Therefore, the anticancer drug-chitosan complex of the present invention can be effectively used for the cancer chemotherapy.
