Clinical and preclinical trials of involving drugs with anti-obesity effects have focused on screening for herbal medicines suspected to have anti-obesity activities. In this study, an extract of Aster scaver Thunb., which was prepared in 80% methanol (ASE), was assessed for its total phenol content, total flavonoid content, antioxidant activity ability to scavenge the ${\alpha}-{\alpha}$-diphenyl-${\beta}$-picrylhydrazyl, 2,2'-azino-bis-[3-ethylbenzthiazoline]-6-sulfonic acid radical, and anti-adipogenic effects. The anti-adipogenic effect of ASE on the differentiation of 3T3-L1 pre-adipocytes to adipocytes was investigated by assaying the suppression of adipocyte differentiation and lipid accumulation by using western blot analysis and the Oil Red-O assay, respectively. The staining results showed that ASE significantly inhibited 3T3-L1. Western blot analysis results showed that ASE decreased the levels of peroxisome proliferator-activated receptor-${\gamma}$, CCAAT/enhancer-binding protein ${\alpha}$, and sterol regulatory element-binding protein 1c. These results demonstrate that ASE directly inhibits the differentiation of preadipocytes, and might be an important adjunct in the therapeutic efforts to reduce adipogenesis.

The purpose of this paper is to design an algorithm for data fusion of sensors data in the helicopter ASE system, using Bayesian Network, which was selected among several knowledge base data fusion methods after consideration and applied to this study. The result of the algorithm analysis shows that Bayesian Network is effective method for solving this problem.

A test on venturi-type premixer of ASE120 engine combustor has been performed to evaluate its mixing performance. Cold air was supplied into the premixer through the fuel nozzle and mixed with the hot air from the compressor exit. The measured temperature of the mixed air was used to evaluate the mixedness. DOE(Design of Experiment) technique was utilized to make a test matrix of variables and to determine the optimum combination of variables, which was verified through a confirmation test.

It is well-known fact that dimensional stability of wood is greatly enhanced by acetylation of wood. This dimensional stability results from bulking of the reacted acetate within the cell wall, which reduces further swelling when the modified woods corne into contact with water or water vapor. The purpose of this research was to determine the water absorption and dimensional stability of the acetylated solid wood in liquid water and in humidity tests. Radiata pine, Siberian larch, and Japanese larch were acetylated. Antiswelling efficiency(ASE) and equilibrium moisture content(EMC) of acetylated wood, at 95% RH and $20^{\circ}C$ after 4weeks, was quite dependent on WPG, but was not dependent on species.

MEMS(Micro Electro Mechanical System) 기술에서 실리콘 식각기술의 중요성으로 플라즈마 식각기술의 개발이 꾸준히 진행되고 있다. 이중에서 ICP(Inductive Coupled Plasma)는 기존의 증착장치에 유도결합식 플라즈마를 추가로 발생시켜 증착막의 특성을 획기적으로 개선시키는 가장 최근에 개발된 기술이며, 이용에너지를 증가시키지 않고도 이용밀도를 높이고 이용업자들에 방향성을 가할 수 있는 새로운 플라즈마 기술로, 주로 MEMS 제조공정에 응용되고 있다. 본 연구에서는 STS-ICP $ASE^{HR}$을 이용하여 식각과 증착공정을 반복하여 식각을 하는 Bosch 식각에 관하여 연구하였다 STS-ICP $ASE^{HR}$ 장비의 Platen power, Coil power 및 Process pressure에 다양한 변화를 주어 각 변수에 따른 식각속도를 관찰하였다. 각 공정별 변수를 변화시킨 결과 Platen power 12W, Coil power 500W, 식각/Passivation Cycle 6/7sec 일 경우 식각속도는 $1.2{\mu}m$/min 이었고, Sidewall profile은 $90{\pm}0.7^{\circ}$로 나타나 매우 우수한 결과를 보였다.

In this paper, we propose All-Optical WDM Buffer System for resolving the contention of Packets in Optical Packet Switching System. The proposed system consists of tunable wavelength converters based on SOA, N×N AWG, and fiber delay lines. This structure can reduce ASE and cross-talk noise because the contending packets are sent and buffered through each different path determined by a wavelength routing. We also performed buffering experiment for two contending WDM optical pulses with each 50ns width, and found that the contending problem is resolved well.

For a fundamental study for high concentration pigment coating, the effects of alkali swellable emulsion (ASE) type rheology modifier and surface adsorption emulsion (SAE) type rheology modifier on both the stability and the viscoelastic behavior of a coating color were elucidated. The coating color prepared with SAE type rheology modifier showed superior thermal and mechanical stability than that with ASE type. In the high concentration and high speed coating process, the mechanical stability of a coating color was a key parameter since both impact force and shear force were increased with the increase of coating color concentration and coating speed, respectively.
