The Spinal cage is the cage-shaped implantable medical device used to treat structural abnormalities caused by degenerative intervertebral disks. In order to secure enough space to provide the mechanical stability and the intervertebral fusion, after removing the intervertebral disc, the Spinal cage is transplanted between the intervertebral space. A hammer is used to push the spinal cage into a narrow space during the spinal cage transplant surgery. Due to the impact and pressure, damage occurs frequently on the spinal cage. In this study, a test model is constructed to measure the value of impulse generally applied on the Spinal cage. The figures of internal impulse before and after the improvement of the Spinal cage are then compared to suggest direction to improve the reliability of the spinal cage.

In this paper, we measured the optical characteristics of the electrodeless fluorescent lamp system as product of the inside and outside of the country and compared the measured data. Power consumption wave of domestic 150W is unstable than it"s of Endura 150W. Optical characteristics(luminance, luminous flux, color rendering index, efficiency, CIE chromaticity coordinate) value of the former is a little small than the latter. In conclusion, if we improve a little more quality then we must secure the superiority in competition.

In this paper, we measured the electrical and optical characteristics of an electrodeless fluorescent lamp system as product of the inside and outside of the country and compared the measured data. Output current wave of domestic 150W is unstable than it"s of Endura 150W. But the former of spend time after discharge and output current value is small than the latter. And optical characteristics(brightness. flux, color rendering index, efficiency) value of the former is a little small than the latter. In conclusion, if we improve a little more quality then we must secure the superiority in competition.
