The study was conducted to investigate the effects of Hydrangea macrophylla var. t1mnbergii extract on blood glucose and lipid concentrations in streptozotocin-induced diabetic rats. Experimental groups were classified into six groups, that is, normal control(Con) group, streptozotocin control(CI) group, Hydrangea macrophylla var. thunbergii(C2) group, hydrangea macrophylla var. thunbergii(50%) + polygonatum odoratum(50%)(C3} group, hydrangea macrophylla var. thunbergii(50%} + Cassia tora(50%)(C4) group, hydrangea macrophylla var. thunbergii(50%) + polygonatum odoratum(25%) + Cassia tora(25%)(C5) group. The blood glucose of C2 and CS groups decreased from 3 weeks. During 6 weeks, the weight of Con group increased S2.93% and C I group decreased S9%. The weight of C2, C3, C4 and CS group \vas 12, 27, 24 and IS%, respectively. The C2 group decreased the fewest. In the CS group, high density lipoprotein(I-IDL) cholesterol(47.4 ± 2.7 mg/dl) decreased the fewest and the triglycerides (63.9 ± 5.2 mg/dl) increased the fewest. Total cholesterol concentration of C2 group(63.8 ± 8.1 mg/dl) was lower t11an the C I group. In conclusion, it seems that Hydrangea macrophylla var. thunbergii extract has an effect on blood glucose, triglycerides, liver function protection etc.

Suggesting countermeasures against traffic noise, the result of modeling the noise level distribution of the apartment using RAYNOISE is as follow. l. Characteristic of Noise Level Attenuation as per Frequency of Apartment Space Comparing the difference of measured values on the balcony and in the enter of the living room had a minus value for an applicable value of 62%, which means the balcony is the path where the, sound is being passed. Because the center of the living room is a closed space, it is considered that the sound became higher by reflection and diffraction of sound in the living room. Change of frequency. Attenuation as per space in the 1st, 5th and 8th floors showed the attenuated condition becoming greater as frequency rose by 1 kHz, and it became greater on the higher floor at 31.5 Hz and 63 Hz. On the 11th floor, 63 Hz appeared to have a higher attenuated condition, and it was attenuated similarly in general. 2. Modeling Using RAYNOISE for Noise Level and Characteristics of Frequency in Apartment Space Noise levels measured on the exterior wall of the apartment, on the balcony and in the center of a living room revealed to be higher in low frequency bandwidths in the lower floors. They decreased on the higher floors including the 7th and 8th floors, increased then decreased again on the 9th floor. The noise level in the living room was 45.3 dB(Z), which appeared to be higher than that of the balcony(41.1 dB(Z)). It was also higher than the balcony in all frequency bandwidths. We then compared noise level in two cases while the window of the living room was open. The first case kept the window of balcony 2(bed room 2 directions) closed while the window of balcony 1(living room directions) remained open. The second case kept the window of balcony 1(living room directions) closed while the window of balcony 2(bed room 2 directions) remained open. The noise level in the center of the living room was 45.0 45.6 dB(Z) in the former case and 28.5 29.5 dB(Z) in the latter, thus showing the attenuated effect of f 5.9 16.6 dB(Z). The attenuated effect appeared to be 16.9 17.9 dB(A) characteristics of A.
광학식 동작 포착 장비를 이용한 노이즈에 강건한 얼굴 애니메이션 제작
박상일(Park, Sang-Il) 한국게임학회 2010 한국게임학회 논문지 Vol.10 No.5
본 논문은 얼굴의 표정과 몸 동작을 광학식 동작 포착장비를 활용하여 동시에 포착하는 경우에 있어 얼굴 부위 마커들에 대한 노이즈에 강건한 데이터 처리 방법에 대해 다룬다. 일반적인 얼굴 표정만 포착하는 경우와 달리, 몸의 움직임과 동시에 포착할 경우 포착용 카메라가 멀리 있어 얼굴에 붙인 마커들의 궤적 데이터는 특별한 처리를 요한다. 특히 궤적의 표식화, 빈 곳 메우기, 노이즈 제거의 과정이 필수적이며, 이러한 과정을 위해 본 논문에서는 지역좌표에 기반을 둔 궤적 데이터 처리 방법을 제안한다. 지역 좌표는 강체변형에 불변한 특징이 있으며, 얼굴모양의 국지적인 변화를 의미하여, 궤적 데이터처리에 효과적으로 활용 될 수 있음을 보였다. 또한 제안한 방법을 활용하여 애니메이션을 제작해 실제 제작 환경에 적용 가능함을 보였다. In this paper, we present a practical method for generating facial animation by using an optical motion capture system. In our setup, we assumed a situation of capturing the body motion and the facial expression simultaneously, which degrades the quality of the captured marker data. To overcome this problem, we provide an integrated framework based on the local coordinate system of each marker for labeling the marker data, hole-filling and removing noises. We justify the method by applying it to generate a short animated film.

The performance test apparatus of liquid-phase plate heat exchanger was installed and the computer program for design was developed in this study. The detail temperature distribution of hot and cold fluids in each path of heat exchanger was calculated by numerical method and the correlation for the heat transfer coefficient was defined. The heat transfer coefficients were measured using the working fluids of water and glycerine to investigate the effect of fluid viscosity. The measured heat transfer coefficients were compared with the calculated values obtained from the computer program and it was shown that error of the calculated values was generally less than 5%.

The heat transfer performance of heating medium oil fluidized bed heat exchanger was measured. The operation variables were air flow rate, air inlet temperature, moisture content, water flow rate and water inlet temperature. The outside heat transfer coefficient was determined from the heat exchanger experiment and its experimental correlation was determined as a function of air velocity and viscosity of heating medium oil. Effect of viscosity was well agreed with the previous studies. Errors of the correlation equation was less than about 10% for outside heat transfer coefficient developed in this study when compared with the measured value. Hot water with the temperature greater than 77℃ could be produced by using the heating medium oil fluidized bed heat exchanger.
