  • It has been shown that the butanol extract of Lonicera japonica has antimicrobial and other potentially useful biological activities. The purpose of this study was to determine the in vitro activity of Lonicera japonica compared to other antimicrobial agents against anaerobic bacteria. Specifically, the in vitro activity of the butanol extract was investigated against 104 clinical isolates of anaerobic bacteria using an agar dilution method and the results were compared to erythromycin, cefoxitin, imipenem, clindamycin, and metronidazole. It was found that Lonicera japonica and imipenem were the most active antimicrobial agents tested.

  • A Hybrid Wall System(HWS) building, Kolon Bundang Tripolis was instrumented to measure the vertical deformation of core-walls and columns. The vertical shortening of individual members were measured at selected floor levels such as 1F, 12F, 25F, and 34F. The measurement has been taken during one year after the construction was started. Together with the measurement, concrete property tests were performed in the laboratory using the concrete obtained in the field. The measured vertical shortenings were compared with the calculated prediction values and the satisfactory agreement was obtained.

  • A solution containing 3-Mercaptopropyltr-imethoxysilane(MPTMS) was employed to modify surface of cotton fabrics with a silver colloid. Silver nanoparticles were applied on cotton fabrics via treatment with 3-MPTMS. The rate of silver nanoparticles on the fabric surface were measured with Energy Dispersive Spectroscopy(EDS). EDS results confirm the silver atom on the cotton surface.

  • LG Electronics developed a perfect flat color display tube which was named "FLATRON" . This tube provides ergonomic performances with perfectly flat face and innovative manufacturing process. Foil transfer is a new technology for manufacturing screen layer for Flatron. Its main features include several properties of film, releasing agent, adhesive, aluminum layer, holes after bake-out and foil transfer process. It will be used innovative and cost oriented process for FLATRON for in CRT mass production..
