The set of all primitive ideals of a non-commutative ring can be topologized be the closure operator and this topological space is called the structure space of the ring. The properties of this space were discussed by Nathan Jacobson in "Structure of ring" pp. 203~209. In this paper, we show that the set of all proper prime ideals of a non-commutative ring can be topologized by the closure operator, and this topological space has the similar properties with the above one.

An experimental study on the water plasma characteristics of removal efficiency for organic contaminants in dye waste water has been investigated. In this study, dielectric barrier discharging electrodes with round shape have disposed cross each other in reactor, and pulse power was supplied to between each electrodes. Its output pulse voltage range is from 0 [V] to 30[kV] and output frequency range is from 100[Hz] to 2[kHz]. Using proposed system, High frequency discharge is tested in the mixed zone(air and water) and the space distribution of streamer corona plasma is observed. In spite of the increasement of voltage and frequency, the proposed system have a stable operation characteristics. It is verified by the experimental results.
