    Abstract: A RNA/DNA nanoparticle for delivering siRNA where a RNA transcript including at least one hairpin structure hybridizes DNA-cholesterol conjugate and folate-DNA conjugate including a complementary sequence to the RNA transcript, and a composition including the RNA/DNA nanoparticle is provided. More specifically, because various siRNA used for different applications can be contained in the RNA/DNA nanoparticle for delivering siRNA at a high loading efficiency, and has stability to the outer attacks such as nuclease degradation. The RNA/DNA nanoparticle siRNA can be prepared by self-assembly without using polycationic agent which is harmful agent for body. The folate targeting to various cancer cells can accumulate the nanoparticle selectively on target cancer cell after intravenous injection, and make excellent gene-silencing effect inside the cancer tissue, thereby being used as a good agent for treating cancers.

    Abstract: In a remote interaction method performed by a remote collaboration system comprising a robot device and a head mounted display, the robot device is located in a remote space and comprising a projector, a panoramic camera and a high resolution camera. The head mounted display is located in a local space apart from the remote space. A communication between the robot device and the head mounted display is established based on a communication request. The remote space is observed by the head mounted display based on first image information and second image information. The first image information is collected by the panoramic camera and received from the robot device. The second image information is collected by the high resolution camera and received from the robot device. Necessary information to be provided to the remote space is searched by the head mounted display based on a result of observing the remote space. The necessary information received from the head mounted display is provided by the robot device to the remote space using the projector.
