Objectives: The purpose of this study is to investigate the effects of Daecheongryong-tang (DCRT) on the adipogenesis in 3T3-L1 preadipocytes. Methods: 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 2 days in the absence or presence of DCRT ranging 0.25 and 2%. The effect of DCRT on adipogenesis was examined by Oil red O staining, and the protein, RNA, and RT-PCR were measured. Results: Our results showed that DCRT decreased the TG content by ORO staining. To elucidate the mechanism of the effects of DCRT on lowering TG content in 3T3-L1 adipocytes, we examined the DCRT modulate expressions of transcription factors to induce adipogenesis and adipogenic genes which is related to the regulation of accumulation of lipids. As a result, the expression of SREBP1, C/$EBP{\beta}$, C/$EBP{\delta}$, C/$EBP{\alpha}$, and $PPAR{\gamma}$ genes, which induce the adipose differentiation and adipose-specific aP2, adipsin, LPL, CD36, TGF-${\beta}$ and adiponectin genes which regulates fat formations, were decreased. In addition, DCRT reduced the expression of iNOS and IL-6 in 3T3-L1 adipocytes, resulting in inflammation. Conclusions: DCRT could regulate transcript factor related to induction of adipose differentiation, inhibit the accumulation of lipids and expression of the adipogenic genes.

This paper presents a design guide for a monopulse cassegrain reflector antenna operating at 35GHz. The Cassegrain antenna consists of main/sub reflectors, a multi-mode feed horn and a monopulse comparator. In the initial optic design of the cassegrain antenna, the blocking areas formed by the sub-reflector and the feed horn and the edge taper at the reflector aperture are carefully considered. The gain patterns of the cassgrain antenna are calculated by employing the ray-tracing method. A monopulse cassegrain antenna is fabricated to verify the proposed method. The measured far-field gain patterns are fairly agreed with the calculated results based on the ray-tracing method. The fabricated antenna has a sum-channel gain of 36.6dB, a 3dB beamwidth of 2.47°, a sidelobe level of less than -20.2dB and a null depth of less than -30.5dB over the difference channel at 35GHz.

Objective : The objective of this study is to investigate treatment results and reasons of difference of treatment result. Method : 22 patients with atopic dermatitis were evaluated for the symptoms and signs according to SCORAD index before and after Oriental medical treatment. And they were divided into two groups(G1: the lower group, G2: the higher group) with 30 scores in standard and analyzed for differences of treatment result. Reasult : 22 patients's Change of total SCORAD index before and after treatment were $35.79{\pm}10.86$ and period were $4.55{\pm}2.94$ months. There were no significant differences between two groups in sex, age, congenital fever, onset and hospital treatment. There were many differences between two groups in the weakness of Digestive system. There were more familial histories in G2 than G1. Past years were $3.20{\pm}3.72$ years in G1 and $1.75{\pm}1.68$ years in G2. There were more deterioration fetors in G1 than G2. Sleep conditions before treatment were worse in G2 than G1 but all children except one were good after treatment. SCORAD index before treatment were worse in G2 than G1. The used herbal medicines were Bangpungtongsungsan gagambang, Yukmijihawangtang gagambang, Saenghyeolyunbuum gagambang. The most frequently used herbal medicine was Bangpungtongsungsan gagambang in G1, Yukmijihawangtang gagambang in G2. Conclusion : On the basis of this study, we thought factors which affected treatment result were the weakness of Digestive system, past years, deterioration factors and SCORAD index before treatment. But this study's cases are small in number so more study is need.

In this paper, design guidelines are derived by analyzing the performance of a shield tunnel in a 915-MHz RFID-based production line products management system. The shield tunnel used in the analysis has the dimension of 35×29×68cm with all of its surface made of metal except for openings for products flow into and out of the tunnel. A half-wave dipole is used for the RFID tag while a half-wave dipole and a ceramic patch are used for the reader antenna. Commercial software is used to analyze the distribution of the reader antennas electric field energy inside the shield tunnel. The path loss (reflection coefficient) is measured in the tunnel environment using a network analyzer. Guidelines in the shield tunnel design are derived from simulation and measurement such as limiting the read region of the reader antenna, suppression of the reading of tags outside the tunnel by lining the tunnels inside surface with electromagnetic absorber, maximizing the reading of inside tags and minimizing the reading of outside tags by properly setting the transmitted power of the reader antenna based on the difference in the received powers of the inside and outside tags.
