Abstract: Provided is a disaster warning system with active geofencing, which includes: an information collection unit for collecting real-time disaster information, real-time weather information and document information on existing disasters; a geofencing analysis unit for complexly analyzing the information to classify the scope of an area that causes a disaster damage after the disaster into caution and danger zones on a map based on geofencing, disaster situations and time series; an information generation unit for generating content for indicating the caution and danger zones on the map; and an information notification unit that provides the received content to a user mobile phone in a section set by a disaster damage prediction range, to allow the user mobile phone to indicate the caution and danger zones on the map.

Abstract: The present invention relates to a nanoliposome-microbubble conjugate, in which a complex of a Cas9 protein, a guide RNA inhibiting SRD5A2 gene expression and a cationic polymer is encapsulated in a nanoliposome, and to a composition for the amelioration or treatment of hair loss containing the same. Currently, drugs used for the treatment of hair loss cause serious side effects such as loss of libido or erectile dysfunction, and hair loss progresses again when drug treatment is stopped. However, when the nanoliposome-microbubble conjugate of the present invention is used, the expression of SRD5A2 inducing hair loss can be fundamentally suppressed, and the treatment of male hair loss can be performed very effectively.

Abstract: The present invention relates to: a porous polymer material having a porous structure over the entire polymer and having a dense porous structure in which pores are connected to each other therein. The porous polymer material is harmless to the human body as it does not use toxic organic solvents. In addition, a porous polymer material can be prepared without using any additives for forming pores and the particle size can be easily controlled, and thus a polymer material suitable for various uses can be prepared. Furthermore, the extended release of a loaded bioactive material is possible only by the dense porous structure of a polymer itself without using an additive and a surface modification method in the porous polymer material of the present invention. Therefore, the porous polymer material can be applied to a biodegradable material in various bio-fields requiring the extended release of a bioactive material.
