A survey of traditional Chinese literary works supports the proposal made in this paper that temporal ideas were more salient than the spatial ones in Chinese architectural tradition. To begin with, spatial ideas on the building form are sought, although no positive conclusion is drawn. Writings by two landscape architects will be analyzed, leading to a positive comment on temporal thought of architecture. In order to support this proposal, the concepts of space and time in sinitic cultural philosophy are discussed, largely through pointing out the infra precepts in the Chinese philosophy, which can be made by surveying the canonic Chinese classic YiJing (or the Book of Changes) and main schools of thoughts - Daoism and Confucianism.

고정도 전류-모드 신호 처리를 위한 새로운 바이폴라 트랜스레지스턴스 증폭기(TRA)와 이것의 오프셋 보상된 TRA를 제안하였다. 두 TRA는 전류 입력을 위한 두 개의 전류 폴로워, 전류차를 얻기 위한 전류 가산기, 전류를 전압으로 변환시키기 위한 저항, 그리고 전압 출력을 위한 전압 폴로워로 구성되었다. 오프셋 보상된 TRA는 TRA의 오프셋 전압을 감소시키기 위한 다이오드 결선된 npn과 pnp 트랜지스터를 채용하였다. 시뮬레이션 결과, TRA근 입-출력 단자에서 0.5 Ω의 임피던스와 40 mV의 오프셋 전압을 갖고 있다는 것이 확인되었다. 오프셋 보상된 TRA는 1.1 mV의 오프셋 전압과 0.25 Ω의 임피던스를 갖고 있다. 두 개의 TRA를 단위-이득의 트랜스레지스턴스를 갖는 전류-전압 변환기로 이용할 때 3-dB 차단 주파수는 40 MHz이다. 제안한 두 TRA의 전력 소비는 11.25 mW이다. Novel bipolar transresistance amplifier(TRA) and its offset-compensated TRA for high-performance current-mode signal processing are described. The TRA consist of two current follower for a current inputs, a current summer for the current-difference, a resistor for the current to voltage converter, and a voltage follower for the voltage output. The offset-compensated TRA adopts diode-connected npn and pnp transistor to reduce offset voltage in the TRA. The simulation results show that the TRA has impedance of 0.5 Ω at the input and the output terminal. The offset voltages at these terminals is 40 mV The offset-compensated TRA has the offset voltage of 1.1 mV and the impedance of 0.25 Ω. The 3-dB cutoff frequency is 40 MHz for the two TRA's when used as a current to voltage converter with unit-gain transresistance. The power dissipation is 11.25 mW.

Objectives : The aim of this study was to investigated the anti-aging and anti-wrinkles effects of the pinus koreaiensis seed(PKS) oil. Methods : The anti-oxidant effect was performed by beta-carotene bleaching assay and the intracellular proteome was analyzed expression of each 15 proteins by 2-D electrophoresis. And fatty acid was analysed by gas chromatography. Anti-wrinkle effect was analyzing human skin by the PRIMOS system. Results : Fatty acid analysis of PKS oil has shown oleic acid was 49.7% and linoleic acid was 34.1%. And the antioxidant effect was about 125% compared with alpha-tocoperol(0.1%) by beta carotene bleaching assay. In 2D PAGE analysis, fifteen protein changes in five mechanisms which was collagen synthesis pathway, MMPs, ECM-cell interaction, cytokine, antioxidant enzymes were analyzed. In case of anti-wrinkle effect was proved in vivo by analyzing human skin by the PRIMOS system. The analysis results of eye wrinkles for 4 weeks showed an improvement effect of over 6%. Conclusions : In this study, the amount of protein change in the five mechanism through the cell experiment and the skin anti wrinkle efficacy by the human in vivo test were investigated. As a result pinus koreaiensis seed oil by supercritical extraction could be used as a anti-aging and anti-wrinkle substance for the skin.

The indoor noise of the naval vessel is very important related to the optimum environmental conditions for crews as well as the ability of fighting power of antisubmarine. Especially, sonar equipment room is one of the rooms where require to be silent because the informations of the underwater noise are collected and analyzed in there. In this paper, the sound reduction of the TASS console, one of the main noise sources in a sonar equipment room for a typical naval vessel, is described. The noise source of this TASS console is the flowing noise of cooling fan. In order to reduce this kind of noise, the plenum chamber and acoustic elbow were developed. Related to the development of the plenum chamber, the area of the air-outlet and sound absorption of the inner lining were investigated experimentally with the evaluation system of the sound insertion loss. Acoustic elbow was also manufactured and evaluated with the evaluation system of the sound insertion loss. Finally, in order to evaluated the ability of noise reduction of the plenum chamber and acoustic elbow, the indoor noise of the sonar equipment was measured when they were appled to TASS console.

The sound field can be classified to the direct, diffract and reverberant sound field. If the sound absorption material in a room is not applied sufficiently, the reverberant sound field increases and the sound pressure in a room also increases when the sound source exists in a room. Therefore, the reverberation time should be controled in order to reduce the reverberant sound as well as sound pressure level in a room. Even though the reverberation time is specified and researched widely in architectural engineering, it is rarely performed in a marine engineering. Therefore, in this research, the reverberation time in a navel vessel is researched related to the noise reduction in a cabin.
