  • The residual life expectancy of the container crane which has been operated more or less 39 years is examined carefully, especially on the boom structure. The basic load and load combination need to be considered for to analyse the boom structure. Various parts of container crane are modeled for to analyse stress, the deflection and the fatigue. Analysis results show that the boom is stable in the stress and deflection but the boom vertical member is over the fatigue life. The rail support beam and boom bottom chord are approximately near the fatigue life. Analysis results show that the residual life of rail support beam and the boom bottom chord would be 2.2 years and 6.8 years, respectively.

  • A calcium-dependent sialic acid-binding lectin has been isolated by thyroglobulin-affinity chromatography from the coastal crab Macrophthalmus Japonicus. This lectin, Macrophthalmus Japonicus lectin (MJL), was eluted with 50mM Tris-HCl, 0.3 M NaCl, 10 mM EDTA, and the recovery yield from the crude protein extract was about 5.6%. The molecular weight of MJL was estimated as 65 kDa in SDS-PAGE both under reducing and non-reducing conditions. MJL induced an agglutination reaction in rabbit, rat, and mouse erythrocytes, but not in human ABO types. This activity was effectively inhibited by sialoglycoproteins such as fetuin, bovine submaxillary mucin, and thyroglobulin.

  • This paper proposes fast speaker adaptation method using artificially distorted speech in telematics terminal under the car noise environment based on eigenspace-based maximum likelihood linear regression (ES-MLLR). The artificially distorted speech is built from adding the various car noise signals collected from a driving car to the speech signal collected from an idling car. Then, in every environment, the transformation matrix is estimated by ES-MLLR using the artificially distorted speech corresponding to the specific noise environment. In test mode, an online model is built by weighted sum of the environment transformation matrices depending on the driving condition. In 3k-word recognition task in the telematics terminal, we achieve a performance superior to ES-MLLR even using the adaptation data collected from the driving condition.

  • In this study, the control of the free surface deformation of a magnetic fluid for the change in electromagnetic force is discussed. The free surface of magnetic fluid is formed by the balance of surface force, gravity, pressure difference, magnetic normal pressure and magnetic body force. Magnetic fluid in characteristics of fluid adjusted to the opposite direction of the gravity direction. Thus, the device of a magnetic fluid proposed the complete zero-leakage sealing, oscillator for surface control, boundary layer control, MHD, flow control, flow using magnetic levitation system and surface actuator. This study show the deformation of surface rise due to the intensity of the magnetic field and possibility of two-dimensional control of magnetic fluid through the feedback data of hall sensor.

  • The study for the quantitative analysis of saikosaponin of Bupleurum falcatum root produced by tissue culture was attempted. The optimal concentration of 2,4-D was 0.1 mg/l for inducing the callus. The induction and growth of the adventitious root from the callus was obtained in the suspension culture containing MS basal medium supplemented with no plant growth regulators. The results of the quantitative analysis of saikosaponins by high performance liquid chromatography (HPLC) showed that the content of saikosaponin a and c was high in the one-year-old root from somatic embryos and that of saikosaponin d was remarkably high in three-months-old adventitious root from callus.

  • This paper presents a novel follicular unit (FU) classification method based on an angle variation of a boundary vector according to the number of hairs in several FU images. The recently developed robotic FU harvest system, ARTAS, classifies through digital imaging the FU type based on the number of hairs with defects in the contour and outline profile of the FU of interest. However, this method has a drawback in that the FU classification is inaccurate because it causes unintended defects in the outline profile of the FU. To overcome this drawback, the proposed method classifies the FU's type by the number of variation points that are calculated using an angle variation a boundary vector. The experimental results show that the proposed method is robust and accurate for various FU shapes, compared to the contour-outline profile FU classification method of the ARTAS system.
