NIC@E is the software developed by authors. The program provides the noise level in outdoors due to various noise source types : construction machines including blast sources, railroad vehicles and automobiles. It operates in the Windows system. In this paper, a highway traffic noise has been evaluated using various types of approach : Ray-tracing method, NIRI method, JAS method. In order to compare the noise estimation performance for various models, a measurement is conducted on a 8 lane express highway at the distance of 25 m and 50 m from the lane. The result shows that the ray tracing and JAS model predict the measured value well within 2dB deviaton. The NIRI model, however, underestimates the highway noise level, as the distance between the source and receiver increases.

각종 monomer를 공중합시킨 고분자 필름의 X선 유기 TSC(thermally-stimulated current)를 측정하고 polyethylene(PE)의 절연성능 개선의 관점에서 공중합 monomer의 영향에 대하여 검토하였다. PE의 X선 유기 TSC 피이크는 결정화도가 높을 수록 고온측으로 이동하였다. X선 유기 TSC에서 피이크는 공중합에 의하여 Br 및 F원자가 0.2~0.4eV의 전자 trap이 도입된 것으로 생각된다.

Through the changes of royal architectural bureau in Gungnaebu, this study attempts to find out the modern transition of traditional facilities belonging to Gungnaebu as well as the constituent of human resources in royal architectural bureau. Yeongseonsa, the royal architectural bureau in Gungnaebu after 1905, was comprised of traditional architectural engineers including Sim Euiseok, and they tried the modern transition of traditional royal facilities gradually. But, Yeongseonsa was transformed to Naejangwon Tomokgwa which was comprised of Kim Yungu and Japanese modern architectural engineers. As Kim Yungu was the modern civil engineer not architectural engineer, Japanese architectural engineers took the lead in the architectural activities of Naejangwon Tomokgwa, and Japanese architectural technology was applied to Korean royal facilities since then.
