Provided is a polypropylene carbonate (hereinafter, PPC) paint composition, and more particularly, a pre-coated metal (PCM) paint composition for coil coating, which is mainly applied to cases for home appliances requiring high hardness, such as cases of a refrigerator. The composition can be used to provide a PCM paint, which has very low smoke density at the time of burning and emits remarkably low amounts of combustion gas and poisonous gas due to combustion at the time of firing, as compared with the existing laminate steel plate and a high-gloss film. In addition, the composition exhibits excellent adhesion to metal materials and excellent durability so that it can be usefully used for a PCM print steel plate applied to home appliances.

A pulsed radio frequency inductive plasma source and method are provided. The source may generate plasma at gas pressures from 1 torr to 2000 torr. By utilizing high power RF generation from fast solid state switches such as Insulated-Gate Bipolar Transistor (IGBT) combined with the resonance circuit, large inductive voltages can be applied to RF antennas to allow rapid gas breakdown from 1-100 μs. After initial breakdown, the same set of switches or an additional rf pulsed power systems are utilized to deliver large amount of rf power, between 10 kW to 10 MW, to the plasmas during the pulse duration of 10 μs-10 ms. In addition, several methods and apparatus for controlling the pulse power delivery, timing gas and materials supply, constructing reactor and substrate structure, and operating pumping system and plasma activated reactive materials delivery system will be disclosed. When combined with the pulsed plasma generation, these apparatuses and the methods can greatly improve the applicability and the efficacy of the industrial plasma processing.

Disclosed herein is an adaptive brain-computer interface device. The brain-computer interface device includes a stimulus generation unit, a signal collection unit, a preprocessing unit, an analysis unit, and a stimuli sequence determination unit. The stimulus generation unit generates stimuli and applies the stimuli to a user. The signal collection unit records the user's Electroencephalogram (EEG) signals generated by the stimuli. The preprocessing unit extracts the feature of P300 on the basis of one of the stimulus from the EEG signals. The analysis unit determines whether P300 is present in the signal extracted by the preprocessing unit. The stimuli sequence determination unit determines the sequence of the stimuli of the stimulus generation unit by inferring a current state from the observations of the analysis unit and selecting an optimum stimulus for the current state.
