  • Fifty-four Korean native and 28 foreign rice varieties harvested in 1998 and 1999 were examined for antioxidative activity that is measured to a chemiluminescence and superoxide radical intensity, by the flow injection chemiluminescence (FI-CL) system and an electron spin resonance (ESR) spectrophotometer, respectively. In the chemiluminescence measurement by FI-CL, radical scavenger activity did not differ significantly among rice varieties between origin types of rice varieties, and between storage periods. GinSun and Hongchoengdo, colored rice exhibited high electron scavenging effect by ESR. Therefore, these results indicate that the pigments of rice varieties may play important antioxidative roles and that it may be possible to breed rice varieties with higher antioxidative potentials.

  • In this study, a new technique for atmospheric transmittance estimated from ALOS PRISM data is developed. It is based on satellite's observing radiances of different view angles and assumes that the cause of difference in radiances is the different view angles. The ALOS PRISM has three independent optical systems for viewing forward and backward and producing a stereoscopic image along the satellite's track. This stereo pair data can be used to estimate the transmittance according to the radiative transfer theory. This derived transmittance will be validated by the AERONET data and compared with the MODTRAN4 simulation results. Results show that the higher the land cover albedo, the better the derived transmittance compared to the AERONET data. Besides, this technique also shows the transmittance retrieval will be underestimated for the low land cover albedo.

  • Objectives: To report the clinical application and effects of Rg3 ginseng (ginseng radix) pharmacopuncture in patients with dry eye syndrome. Methods: Six patients who suffered from dry eye syndrome were treated with Rg3 ginseng pharmacopuncture for 4 weeks. The Ocular Surface Disease Index (OSDI) was used twice, at the start and end of treatment, to analyze the results. Results: After treatment with Rg3 ginseng pharmacopuncture, OSDI scores were improved in all six patients. Conclusion: Rg3 ginseng pharmacopuncture is an effective treatment for patients with the symptoms of dry eye syndrome.

  • 16 chicken isolates and four clinical isolates of VanB-vanA incongruent vancomycinresistant Enterococcus faecium strains without vanS were isolated in 1999. Pulsed-field gel electrophoresis revealed only a peripheral relationship between the chicken isolates and clinical isolates, but suggested clonal spread in the chicken isolates.

  • In this paper, we design the signal processing unit to effectively support the proposed algorithm for an automotive Frequency Modulation Continuous Wave(FMCW) radar. In the proposed method, we can obtain the distance and velocity with improved error depending on each range(long, middle, and short) of the target. Since a high computational capacity is required to obtain more accurate distance and velocity for target in near range, the proposed signal processing unit employs the time de-interleaving and the frequency interpolation method to overcome the limitation. Moreover, for real-time signal processing, the parallel architecture is used to extract simultaneously the distance and velocity in each range.

  • The purpose of this review are to determine of role of physical therapist in silver industry, and to give the information about elderly person when silver industry will be needed in 21 centry. Current literature so physiological changes that occur in humans owing to aging is reviewed. Also, psychological changes are discussed. There are main important roles in silver industry. One is proper exercise prescription for helth care and the other is effective therapy for the various disease. It will help the elderly person who needs independent ADL.

  • This paper describes a numerical and experimental study on the stability and failure behaviour of rectangular symmetric laminated composite plates. The plates are simply supported along the unloaded edges and clamped along the loaded ends, and they are subjected to uniaxial in-plane compression. The finite element method was employed for the theoretical study. The study examines the effect of the plate's stacking sequence and aspect ratio on the stability and failure response of rectangular symmetric laminated carbon fibre reinforced plastics composite plates. The study also includes the effect of the unloaded edge support conditions on the postbuckling response and failure of the plates. Extensive experimental investigation were also carried out to supplement the finite element study. A comprehensive comparison between theory and experimental data are presented and discussed in this contribution.

  • In this study, we investigated the effects of the post Ar plasma treatment at different RF powers for various durations on electrical, structural, and optical properties of relatively thin Al-doped zinc oxide films. The sheet resistance was observed to decrease rapidly for the first 5min, beyond which the resistance apparently saturated. As the RF power increased, the grain size and the interplanar distance of (002) planes also increased. The observed decrease in sheet resistance was stated to be a consequence of Al and/or Zn interstitials as well as grain growth. It was also found that Ar plasma treatment increased the transmittance of Al-doped zinc oxide films in most of the visible light range below the blue light.

  • Explants of mature root tissues and calli derived from root and cotyledon of Panax ginseng were cultured in vitro on Murashige and Skoog medium supplemented with 2, 4-dichlorophen-oxyacetic acid(3,4-D), naphthaleneacetic acid(NAA), benzyladenine, and gibberellic acid to assess their capacity to regenerate organs. Root formation at high percentage (46.2-61.1%) was obtained 20-30 days after culturing on media supplemented with combinations of NAA(5 mg/l) and kinetin (1 mg/l), And calli derived from cotyledon produced numerous embryoids in media($\frac{1}{2}$MS) containing 2,4-D(0.5 mg/l) and kinetin (0.5 mg/l). Reculture of these embryoids in media($\frac{1}{2}$MS) enriched with 1 mg/l of benzyladenine and 1 mg/l of gibberellic acid resulted in more plantlet regeneration.

  • Effects of $O_2$ flow during deposition on Si crystallization at low substrate temperature were studied. Silicon thin films were prepared on $SiO_2$ substrates in a low-pressure chemical vapor deposition chamber using a mixture of $SiH_4$ and $H_2$. In some cases $O_2$ was intentionally introduced during deposition. Growth of poly silicon was observed at the substrate temperature as low as $480^{\circ}C$ when $O_2$ was flowed during deposition implying that crystallization of Si was enhanced by $O_2$ flow. On the other hand, $O_2$ flow did not show any significant effects at higher substrate temperature, where deposition rate is relatively fast. Enhancement mechanism of Si crystallization by $O_2$ flow was suggested from these results.
