Abstract: Disclosed is an image data generating method. Operations of emitting electromagnetic waves to an object and receiving scan signals scanning the object are performed by using a multi-static transceiver. First image data of a low resolution are generated based on the scan signals. when a first condition associated with the first image data is satisfied, second image data of a high resolution associated with a sub-region of the first image data are generated. When a second condition associated with the second image is satisfied, third image data based on the first image data and the second image data are generated.

Abstract: Provided are a PCR buffer composition for increasing the activity of a DNA polymerase having increased gene mutation specificity, a PCR kit for detecting a gene mutation or SNP comprising the PCR buffer composition and/or the DNA polymerase having increased gene mutation specificity, and a method for in vitro detecting one or more gene mutations or SNPs in one or more templates by using the kit.

Abstract: Provided is a display device. The display device includes a display panel which includes a base substrate, a thin-film transistor layer on the base substrate, and a light emitting element layer comprising light emitting elements on the thin-film transistor layer; a cover window on the light emitting element layer of the display panel; and a fingerprint recognition sensor layer under the display panel. The base substrate includes a first base, a second base on the first base, and a light blocking layer between the first base and the second base, and the light blocking layer includes holes through which light reflected by a finger touching the cover window passes.

Abstract: A drug delivery system having an inner core-shell like structure containing a poorly soluble camptothecin compound and a water-soluble camptothecin compound, and an outer amphiphilic polymer shell surrounding the inner core-shell like structure, a manufacturing method therefor, and uses of the drug delivery system in treating cancer are disclosed. The core-shell structured particles form very stable particles and show a mono-distribution of particles before and after freeze-drying. The particles show excellent results compared with existing particles which do not contain the inner core-shell like structure, in animal efficacy tests and pharmacokinetic tests.
