Abstract: The present invention relates to an arm-fastening device for a pulse diagnosis, a pulse sensor, a pulse diagnosis apparatus comprising the device and sensor, and a method for manufacturing the pulse sensor. Embodiments of the present invention permit the pulse of a person to be examined to be correctly measured in the state in which the person to be examined is a comfortable one when the pulse of the person to be examined is being measured.

Abstract: The present invention relates to a method of detecting a skin-colored area using a variable skin color model. In the method, an initial skin-colored area is extracted from an input image using a skin color model, the initial skin-colored area being repeatedly extracted by adjusting a threshold value, which is a criterion for the selection of a skin-colored area, until a ratio of size of the extracted skin-colored area to size of the entire input image becomes less than a predetermined value. A skin-colored area is extracted by applying the threshold value determined in the first stage to the skin color model, the skin color model being modified by analyzing characteristics of object regions and noise regions of the skin-colored area. The skin-colored area detection method can obtain a high skin-colored object detection rate and a high false alarm rate even under various lighting and background conditions.

Abstract: The present invention relates to a cigarette paper with a coating material for Low Ignition Propensity (LIP) and a fire-safe cigarette having the same. More particularly, the present invention manufacture a cigarette paper by coating a pre-determined area with a coating material for LIP to lower a porosity of the cigarette paper, and relates to a cigarette paper which retains original flavor and taste of the cigarette and has an improved fire-safety and a cigarette having the same. The present invention provides a cigarette paper containing a coating material for LIP having an improved quality as compared to a conventional composition applicable to a fire-safe cigarette and thus capable of retaining the original flavor of the cigarette as well as having ash integrity, and cigarette having the same.

Abstract: Provided is a three-dimensional model classification method of classifying constitutions.

Abstract: Disclosed herein is a system for diagnosing a deficient pulse and an forceful pulse. The system includes a pulse diagnotic device, a deficient pulse and forceful pulse determining device, and an output device. The pulse diagnotic device measures pulse condition information at an examinee's Cun (˜\f˜) Gu (H), and Chi (,R) pulse-taking locations on his or her wrist using one or more pulse-taking sensors. The deficient pulse and forceful pulse determining device is operably connected to the pulse diagnotic device, analyzes the pulse pressure information measured by the pulse diagnotic device, calculates a quantified deficiency/forceful coefficient, and determines whether a pulse of interest is a deficient pulse or an forceful pulse. The output device is connected to the determining device and displays results of the determination.

Abstract: An axial flow fan shroud fixes and supports the axial flow fan and a driving motor while surrounding the axial flow fan. The shroud includes a housing having a ventilation hole at the center of the housing and surrounding the axial flow fan; a motor fixing part at the center of the ventilation hole; and air guide vanes or duct between the housing and the motor fixing part for deflecting a part of air blown by the axial flow fan parts needing cooling. The shroud prevents overheating of parts sensitive to heat due to heat of an engine by guiding air blown by the axial flow fan to an area where the parts are installed while avoiding the heated engine. Therefore, low-price products having inferior thermal property can be used so manufacturing costs can be reduced and the degree of freedom in design can be improved.

Abstract: Methods for performing a direct enzymatic reaction involving a nucleic acid molecule include performing the enzymatic reaction directly using a biological specimen in a reaction mixture containing a zwitterionic buffer and/or a non-reducing carbohydrate to prevent the biological specimen from inhibiting the enzymatic reaction, in which a nucleic acid molecule present in the biological specimen is not purified before the enzymatic reaction, and obtaining a product from the enzymatic reaction.

Abstract: Disclosed therein is a shroud for an axial flow fan, which can fix and support the axial flow fan and a driving motor while surrounding the axial flow fan. The shroud for the axial flow fan includes a housing having a ventilation hole (10a) formed at the center thereof and surrounding the axial flow fan (2); a motor fixing part (12) mounted at the center of the ventilation hole; and guide means (13, 14) disposed between the housing (10) and the motor fixing part (12) for deflectively guiding a part of air blown by the axial flow fan (2) in a direction in which parts needing cooling are installed. The shroud can prevent overheat of the parts sensitive to heat due to heat of an engine by guiding air blown by the axial flow fan to an area where the parts are installed while avoiding the heated engine.

Abstract: An auto lift ceiling lighting system in which the width of left and right rotary drums is formed as wide as the width of the flat cable and the flat cable is wound stably and vertically on the outer surface of the winding core in the left and right rotary drums so as not to become twisted. In the auto lift ceiling lighting system, the lamp can be turned on and off at any position and the flat cable supplying the electric power to the lamp does not become twisted and the balance of the lamp is maintained while the lamp ascends and descends.

Abstract: Disclosed is a flow force compensating spool valve having a flow force compensating protrusion ring at a supply channel of a sleeve on an outer circumference portion of a spool rod, and a hydraulic valve, a pneumatic valve, a three-way valve, and a four-way valve using the spool valve, in which the flow force can be compensated by a simple structure change of the spool without changing a structure of the sleeve.

Abstract: Provided is an auto lift ceiling lighting system in which the width of the left and right rotary drums is formed as wide as the width of the flat cable and the flat cable is winded stably and vertically on the outer surface of the winding core in the left and right rotary drums when winded by the motor, thereby not to be twisted. In the auto lift ceiling lighting system, the lamp can be turned on and off at any position and the flat cable supplying the electric power to the lamp is not twisted and the balance of the lamp is kept while the lamp ascends and descends.

Abstract: A fan includes a hub coupled to a driving shaft of a motor, a plurality of blades installed on the outer circumferential surface of the hub to be spaced from each other at a predetermined interval, and a band connecting free ends of the blades. An axial direction width (W1) between a leading edge and a trailing edge at the free end of each of the blades is greater than a width (W2) of the band.
