  • The structural stress and vibration analysis of the rotary screen are investigated. The mechanical properties of the rotary screen, this is, Young's modulus and density of nickel alloy are determined experimentally. The natural vibration characteristics of the rotary screen are evaluated and the displacement, the stress of the rotary screen under the various load conditions are also examined. The radial displacement of the rotary screen is obtained by experiment under various rotating speeds.

  • Electroforming is a kind of metal molding technology. After gilding on the possession object(conductivity, nonconductivity) separate it with possession object and produce a part or duplicate. This process has an excellent ability of duplicating detailed figure. To simplify the manufacturing process of a rotary screen, this study was adopted electroforming technology and produced silicon rubber mandrel. Furthermore, to indicate the optimal condition for the acquisition of high-qualified rotary screen product, the experiment was executed with pH, time, sulfamate nickel solution according to density which were the main factors to decide the condition, then compared it with the product made by original "S" company in Holland. As a result, the figure of hole was more obvious and correct. Also the open size increased by more than 2-3%.

  • Purpose: The purpose of this study was to determine the effects of a functional movement correction exercise on the functional movement screen scores of badminton players. Methods: The participants consisted of 25 badminton players who were randomly assigned to an experimental group (n = 13) or a control group (n = 12); they engaged in exercise three times per week for eight weeks. The experimental group engaged in the functional movement correction exercise, while the control group engaged in general exercise. An FMS kit (USA) was used to measure the following: FMS score, deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push up, and rotary stability. Results: The FMS score, deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, and trunk stability push up, and rotary stability showed significant improvement in the experimental group (p < 0.05). Conclusion: The experiment confirmed that the functional movement screen scores of badminton players improve with effective exercise interventions.

  • A dust injection system was developed for the lime calcining rotary kiln for the coke dust from the coke dry quenching(CDQ) facility to be used as a fuel. The CDQ dust was injected with the gaseous fuel through the hole in the burner. In order to prevent the spot heating large particles should be removed from dust and dust should be injected as fast as possible so that particle combustion lasts as long as possible without precipitation. This is especially necessary when dust is burned together with gaseous fuel because the gaseous fuel can not go so far and in addition dust combustion aggravates hot spot heating. In this research a rotation drum screen was used to remove particles with diameter larger than 4mm and dust injection speed was 40m/sec. And the burner was adjusted not to use swirl that hinders flame go far away. With these measures scale generation iside the kiln could be reduced to be negligible and in addition NOx emission could be reduced from 150ppm to 20ppm. The fuel reduction was about 85Mcal/T-lime.
