Abstract: An embodiment includes a method of texturing a semiconductor substrate, a semiconductor substrate manufactured using the method, and a solar cell including the semiconductor substrate, the method including: forming metal nanoparticles on a semiconductor substrate, primarily etching the semiconductor substrate, removing the metal nanoparticles, and secondarily etching the primarily etched semiconductor substrate to form nanostructures.

Abstract: Disclosed are an ?v?3 integrin targeting single-domain antibody and various applications thereof. The ?v?3 integrin targeting single-domain antibody exhibits high binding ability to ?v?3 integrin related to angiogenesis, excellent tissue permeability, and biostability compared to conventional antibodies. Further, the single-domain antibody may be combined with fluorescent particles and thus may be easily measured in vitro, in vivo or ex vivo, and may be effective in detecting angiogenesis and diagnosing angiogenesis related diseases, therefore it may be usefully used in related industries.

Abstract: Provided is an image forming apparatus to control capturing of an execution screen displayed. A memory stores at least one application. A user interface device displays an execution screen of an application, to which a user is logged in with an identification (ID) of the user, and receives an input of capturing the execution screen. A processor determines an authority of the ID of the user to capture the execution screen by comparing a security level of the execution screen set based on the data displayed on the execution screen and a security level of the user set with respect to the ID of the user. The processor, in response to the input, controls the capturing of the execution screen, based on the determined authority of the ID of the first user.

Abstract: An image forming apparatus to selectively perform an auto color registration operation, the apparatus including: a printing unit, which forms single-color images, based on printing data, and transfers the images to a printing medium to form a printed image; and a controller which prevents the printing unit from performing the auto color registration operation on the printing data, if the printing data relates a monochromatic printing mode.
