        Sheet형 전파흡수체를 제조하고 그들의 전자파 흡수 특성을 조사하였다. 제조된 ferrite 흡수체의 흡수특성은 2.4~3.2GHz의 주파수범위에서 입자크기의 감소에 따라 개선되었다.

        The concentration of Total Suspended Particulates(T.S.P), size distribution of suspended particulates, and soluble anions of T.S.P in atmosphere of industrial region in Busan were investigated. T.S.P was measured by High-Volume Air Sampler and particle size distribution was measured by Andersen Air Sampler. We analyzed the chemical component of the T.S.P by Ion Chromatography and measured the shape and size of T.S.P by Scanning Electron Micrography. The small size of T.S.P mainly exist in industrial region, but the large size of T.S.P mainly exist in residentail area.
