  • We reported a P/M soft magnetic material with core loss value of $W_{10/1k}=68W/kg$, which is lower than that of 0.35mm-thick laminated material, by using high purity gas-atomized iron powder. Lack of mechanical strength and high cost of powder production are significant issues for industrial use. In order to achieve both low core loss and high strength by using inexpencive powder, the improvement of powder shape and surface morphology and binder strength was conducted. As the result, the material based on water-atomized powder with 80 MPa of TRS and 108 W/kg of core loss (W10/1k) was achieved.

  • A control system was developed for raw material yards of the works of a metal industry. It is devoted to the automatic operations of the raw material yards stackers, and to the improvement of the stacking method to stack granular coal uniformly. The system automatically controls the stacking operations without human intervention, and also prevents any collision between cranes, stackers, jibloaders and the level-roughing cranes.

  • Ink-jet printed (IJP) self-aligned (SA) organic light emitting diodes (OLEDs) and its application to light emitting seal have investigated. Ink-jet printing of light emitting material is carried out onto transparent anode covered with insulating material. Laminated light emitting seal with SA IJP OLED without photo - lithographic process and any vacuum process, noncontact type electromagnetic power supply without electric power supply line, and light emitting tag with network type RF communication terminal by controlling display information were demonstrated.

  • 생명체의 본질적 기능에 중요한 역할을 담당하는 유전자들을 밝히기 위해 미생물 유전체들 사이의 공통적 유전자를 밝히는 COG알고리듬을 이용하였다. 진핵생물 3종을 포함한 66종의 미생물에서 63개의 유전자가 보존적이었으며, 단백질 합성에 관여하는 유전자들이 총 52개로 생명현상에서의 단백질의 중요성을 알 수 있었다. 각 보존적 유전자들의 distance value를 이용하여 종간의 유전자 변이의 정도를 보면, ribosomal protein S12 (COG0048)와 ribosomal protein L14 (COG0093)의 보존성이 가장 높았다. 보존적 유전자들의 평균과 분산으로 유전체 분석을 수행한 결과, 고세균과 진정세균의 각 그룹 등 근연종들이 독자적 그룹을 형성하였다. 하지만 각 그룹내의 속 및 유전체의 수와 유전체 변이의 정도는 비례하지 않는 것을 알 수 있었다.
