Abstract: An apparatus and method for measuring air currents on the surface of a substrate, which can accurately measure the magnitude and direction of air currents on the surface of a wafer with wafer-type air current measurement sensors, are provided. The apparatus includes: a first air current measurement module measuring a magnitude of air currents on a surface of a first substrate, which is processed in accordance with a semiconductor manufacturing process; a second air current measurement module measuring a movement direction of the air currents; and a power module supplying power to the first and second air current measurement modules, wherein the first air current measurement module, the second air current measurement module, and the power module are mounted on a second substrate, which has the same shape as the first substrate.

Abstract: An encoding/decoding apparatus and method for controlling a channel signal is disclosed, wherein the encoding apparatus may include an encoder to encode an object signal, a channel signal, and rendering information for the channel signal, and a bit stream generator to generate, as a bit stream, the encoded object signal, the encoded channel signal, and the encoded rendering information for the channel signal.

Abstract: A mobile device for measuring radon in groundwater is proposed. The mobile device for measuring radon in groundwater has an effect in that the mobile device enables a user to achieve the same level of reliability as the conventional technology, a previously applied separate dehumidifying device is not required in measuring the radon concentration in groundwater, and while moving from site to site, the user is able to quickly measure the radon concentration in groundwater by the mobile device with a simple configuration and low cost.
