Abstract: An electronic device is provided. The electronic device includes a display configured to output a screen on which a web browser is executed, an input device comprising input circuitry configured to integrate with the display or be independent of the display, a communication circuit configured establish a communication channel with the network via a wired or wireless communication connection, a processor configured to be electrically connected with the communication circuit, the display, and the input device, and a memory configured to store a program and instructions for the web browser and be electrically connected with the processor.

Abstract: A semiconductor test device includes an actuator holding a radiation source and adjusting a distance between the radiation source and a sample, and a controller controlling an operation of the actuator and calculating a soft error rate (SER) of the sample based on the distance between the radiation source and the sample. The controller calculates a first distance between the radiation source and the sample at which the SER of the sample becomes zero, and calculates a metal-to-dielectric ratio of the sample based on the first distance.

Abstract: A novel isolated microorganism, Micrococcus luteus KCTC 0369BP, exhibits a linear survival curve versus the concentration of hydrogen peroxide and is thus useful in a method of determining the degree of sterilization of, for example, ultrapure water that has been sterilized by hydrogen peroxide. The novel isolated microorganism produces a surface polysaccharide and a catalase.
