The relative dielectric constant of epoxy fiber glass was indirectly measured by using a simple method developed by Napoli and Hughes. Theoretical resonant frequencies of open-edged rectangular cavity were calculated and compare with the measured resonant frequencies. Modes could be identified through this comparison. Relative dielectric constant could be indirectly obtained from both measured frequencies and mode informations.

Equalization of satellite communication using Complex-Bilinear Recurrent Neural Network(C-BLRNN) is proposed in this pater. Since the BLRNN is based on the bilinear polynomial and it has been more effectively used in modeling highly nonlinear systems with time-series characteristics than multi-layer perception type neural networks(MLPNN) , it can be applied to satellite equalizer. the proposed C-BLRNN based equalizer for M-PSK with a channel model is compared with Volterra filter Equalizer, DFE, and conventional Complex MLPNN Equlizer. The results show that the proposed C-BLRNN based equalizer gives very favorable results in both of MSE and BER criteria over other equalizers.

A planar log-periodic antenna covering 400∼1000MHz has been developed by using printed circuit board and photo etching technique. Also the wide band coaxial cable balun has been developed for measuring the characteristics of this antenna. The experimental results show that the antenna developed has characteristics nearly similar to those of a half-wave dipole and this antenna is superior to loop antenna and indoor dipole antenna in UHF band. Low cost, mass producibility and small size are the merits of this antenna.

H.James의 작품을 이해하려면 그의 문체에 대한 문제가 매우 중요한데도, 워낙 광범위한 점 때문인지 제임스비평에서는 회피되고 있는 점이 놀랍다. 문체론과 신비평 이후 제임스의 작품이 많이 다루어짐으로 우리에게 새로운 통찰력을 제시해주었으며 영미문학에 새로운 장을 열어 주었으니, 단편적인 분석에 그치고 있다.
