A phytosociological study of the forest vegetation was carried out in Mt. Chongok and Mt. Tuta from June, 1992 to August, 1993. The forest vegetation was classified into 1 order, 2 alliances, 1 suballiance and 4 communities; Vaccinium hirtum v. koreanum-Quercus monogolica community, Carex humilis v. nana-Pinus densiflora community, Sasa borealis-Carapinus laxiflora community, Plectranthus inflexus-Quercus variabilis community. Actual vegetation map was drawn in 1:25,000 scale.

This study is mainly concerned with vibration control of L-type reciprocating air compressor by a dynamic vibration absorber. The dynamic vibration absorber of reciprocating air compressor was designed for constant revolution running condition. For the review, Vibration test was conducted for the performance appraisal of installed dynamic vibration absorber in the reciprocating air compressor. As a result of the test, the performance of dynamic vibration absorber was satisfactory.

The system discussed in this paper is an integrated stand-alone system with the full functional capabilities required of a telerobot system. It is complete with a force-reflecting 6-DOF hand controller, driving a PUMA 560 or 762 robot, with an integrated force-torque sensing wrist sensor and servo-driven parallel jaw gripper. A mix of custom and standard electronics, distributed computers and microprocessors, with embedded and downloadable software, have been integrated into the system, giving rise to a powerful and flexible teleautonomous control system.

NATM technic had been applied to Nakaya tunnel of Sin kan express R.R lines in 1975. on the worst expandable geological conditions, application of NATM method was carried out good result. Measurement data which include convergencymeter, inclinometer, extensometor load-cell, strain gage data of shotcrete stress and steel arch. was explained with slides. Induced NATM technic has been improved since 1975 as follows, specially adhesive method of shotcrete instead of spray method such as tunnel swift lining Sliding press lining, clean lining by pumping and sweeping tote lining ets.

In this paper, we analyze the harmonic flux distribution of squirrel cage induction motor with the different stator/rotor slot combination(36/42 and 36/44) using Finite Element Method and fast Fourier transform. These result will be used to obtain dips & cusps (harmonic torque) in torque characteristic curve.

Amorphous diamond has a very low work function (1 eV) at modest temperature ($150^{\circ}C$). It has been coat coated on electron emitting electrodes. Such electrodes are used for cold cathode fluorescence lamps (CCFL) that illuminate liquid crystal displays (LCD) for rnote books and television sets. Amorphous diamond can dramatically reduce the turn-on voltage to lit CCFL so the lamp life can be greatly extended. Moreover, the electrical current can be increased to enhance the brightness of the light.
