Abstract: The present invention relates to a golf club in which a shaft arranged beneath a grip portion of the golf club is processed to be used as means for grip swing performed by rotating the golf grip locally between both hands of a golfer. The aim of the present invention is to enable forces of both hands and both arms of the golfer and the weight of the golf club to be dynamically balanced at one or more center of gravity portions (S) designed at a specific position on the shaft beneath the grip during a typical gripping and swinging action of the golfer, that is, said center of gravity portions (S) may serve as a hinge or weight of minimum swing performed between both hands of the golfer, thereby enabling fine swing control.

Abstract: A method for non-invasively determining pulmonary characteristics by measuring breath gas and blood gas and a display apparatus for the same, and for estimating major physiological characteristics, such as respiratory characteristics of lungs-pulmonary circulation system, cardiac functional characteristics, structural characteristics of lungs, etc. by applying primary measurement parameters obtained from ventilation gas and blood during breathing; and a display apparatus useful for the same.

Abstract: The present invention relates to a method and apparatus for manufacturing a carbon nano tube, and more particularly, to a method and apparatus for manufacturing a carbon nano tube by which a carbon nano tube having a uniform property and high purity can be manufactured by uniformly raising a temperature of reaction gas, which includes a gaseous transition metal catalyst precursor compound and gaseous carbon compound contained in a hermetically closed reaction space, to the Boudouard reaction temperature.

Abstract: Disclosed are a method for determining respiratory characteristics of lung-pulmonary circulation system by respiratory blood gas and blood gas data, and a displaying instrument for the same. More particularly, the present invention describes a method for determining respiratory characteristics of the lung-pulmonary circulation system by using respiratory blood gas and blood gas data and a display instrument for the same, so that the present invention provides partial O2 and/or CO2 pressure in other major parts, as well as shunt ratio of lungs and physiological dead space ratio by locally applying partial O2 and/or CO2 pressure information in lung-pulmonary circulation system in which gas-exchange is performed, and offers medical information such as cardiac output of a heart per beat.
