Objective This study was undertaken to determine the effect of Whallak-tang on expression of CD/cytokine Genes. Methods The expression of CD/Cytokine Genes were examined by cDNA microarray using the human mast cell line(HMC-1). Results The expression of ATP5F1, FLJ20671, unknown, KIAA0342, OAS2, unknown genes were increased in $200{\sim}300%$ range. The expression of unknown, MDS006, IFITM1, MRPL3, ZNF207, FTH1, FBP1, NRGN, NR1H2, KIAA0747 genes were decreased in $0{\sim}33%$ range. Conclusion These results would provide important basic data on the possibility of the clinical treatment of Whallak-tang in musculoskeletal disease.

Used in the ceramic tile market as a representative building material, relief ceramic tile is showing increased demand recently. Since ceramic tiles are manufactured through a sintering process at over 1,000 ℃ after uniaxial compression molding by loading granule powders into a mold, it is very important to secure the flowability of granular powders in a mold having a relief pattern. In this study, kaolin, silica, and feldspar are used as starting materials to prepare granule powders by a spray dryer process; the surface of the granule powders is subject to hydrophobic treatment with various concentrations of stearic acid. The effect on the flowability of the granular powder according to the change of stearic acid concentration is confirmed by measuring the angle of repose, tap density, and compressibility, and the occurrence of cracks in the green body produced in the mold with the relief pattern is observed. Then, the green body is sintered by a fast firing process, and the water absorption, flexural strength, and durability are evaluated. The surface treatment of the granule powders with stearic acid improves the flowability of the granule powders, leading to a dense microstructure of the sintered body. Finally, the hydrophobic treatment of the granule powders makes it possible to manufacture relief ceramic tiles having a flexural strength of 292 N/cm, a water absorption of 0.91 %, and excellent mechanical durability.

Cultural difference and interference have become major keywords that spread and transmit mass culture. Movie icons in particular serve to lead functions of mass culture. Pondering substantively over the way visual media interfere with text media and give rise to differences or the way they are branching out could serve as a key leading to a more profound understanding of contemporary culture. From a textual standpoint, 'Bug Story'(1984) is an epic description symbolizing 'Kwangju' intensely and metaphorically. Comparing and analyzing the way it is modulated through 'Milyang' (2007), an adjacent genre, or the way the politics of the differences is sublimated aesthetically could be a thesis that helps distinguish between interference in terms of genre and its descriptive differences. 'Milyang' portrays again the importance of description in a movie by constructing, by means of a movie,outstanding descriptive techniques of the original text and theme. In other words, this means a towering achievement of the movie mechanism as an 'aesthetical torture' toward which Lee, Chang-Dong's movie is oriented.
