Objectives: The purpose of this study is to investigate the clinical effects of heating-conduction therapy on lateral ligament injury induced by ankle sprain grade II. Methods: The 67 outpatients who were diagnosed as ankle sprain grade II were performed heating-conduction acupuncture therapy on lateral ligament injury. To evaluate the efficiency of heating-conduction acupuncture therapy, pain threshold with pressure algometer and visual analogue scale(VAS) were applied pretreatment and after 1st, 2nd treatment. Results: 1. The pain threshold and VAS score after 1st and 2nd treatment with an isolated injury of the anterior talofibular ligament showed statistically significant improvement compared with pretreatment. 2. The VAS score after 1st and 2nd treatment with an combined injury to the anterior talofibular and the calcaneofibular ligament showed statistically significant improvement compared with pretreatment. 3. The VAS score after 1st and 2nd treatment with an combined injury to the anterior talofibular, calcaneofibular and posterior talofibular ligament showed statistically significant improvement compared with pretreatment. 4. After 1st and 2nd treatment on the posterior talofibular ligament and after 2nd treatment on the anterior taofibular and calcaneofibular ligament with an combined injury to the anterior talofibular, calcaneofibular and posterior talofibular ligament the pain threshold showed statistically significant improvement compared with pretreatment. 5. Between isolated injury and combined injury of lateral ligament, the difference in pain threshold and VAS score was not statistically significant. Conclusions: Heating-conduction acupuncture therapy has clinical effects of pain reduction on patient with an isolated injury and combined injury of lateral ligament induced by ankle sprain grade II.

A new electrostatic rotary atomizing painting equipment using air turbine was developed for high transfer efficiency. Based on the overall design requirements of painting equipment, basic design specifications of the equipment parts such as air turbine and atomizing disk ate defined from the present conceptual design model. Air turbine is designed with the section profile of NACA airfoil, and its internal flow field is analyzed by commercial CFD code. Atomizing disk is designed to achieve the ligament type spray of paint with the use of visualization technique. Various experiments and tests are conducted to investigate the spray and the transfer characteristics of newly-designed painting equipment, and the measurement results are compared with the those of conventional painting equipments. The comparison results show the present painting equipment is superior to the conventional ones in the aspects of transfer efficiency and coating surface characteristics.

Objectives : The purpose of this study is to investigate the clinical effects of heating-conduction acupuncture therapy on lumbago induced by iliolumbar ligament sprain. Methods : From September 25 to December 30, 2009, the 8 outpatients who had admitted to department of oriental rehabilitation medicine, Dae-Jeon oriental medical hospital, Dae-Jeon university, with acute lumbago were performed heating-conduction acupuncture therapy on iliolumbar ligament sprain.

For a perforated plate, it is challenging to develop a finite element model due to the necessity of the fine meshing of the plate, especially if it is submerged in fluid. This necessitates the use of a solid plate with equivalent material properties. Unfortunately, the effective elastic constants suggested by the ASME code are deemed not valid for a modal analysis. Therefore, in this study the equivalent material properties of a perforated plate are suggested by performing several finite element analyses with respect to the ligament efficiencies.

In this study, the natural frequencies of the perforated square plate with a square penetration pattern are obtained as a function of ligament efficiency using the commercial finite-element analysis code ANSYS. In addition, they are used to extract the effective modulus of elasticity under an assumption of a constant Poisson's ratio. The effective modulus of elasticity of the fully perforated square plate is applied to the modal analysis of a partially perforated square plate using a homogeneous finite-element analysis model. The natural frequencies and the corresponding mode shapes of the homogeneous model are compared with the results of the detailed finite-element analysis model of the partially perforated square plate to check the validity of the effective modulus of elasticity. In addition, the theoretical method to calculate the natural frequencies of a partially perforated square plate with fixed edges is suggested according to the Rayleigh-Ritz method.

An analytical method to estimate the coupled frequencies of the circular plate submerged in fluid is developed using the finite Fourier-Bessel series expansion and Rayleigh-Ritz method. To verify the validity of the analytical method developed, finite element method is used and the frequency comparisons between them are found to be in good agreement. For the perforated plate submerged in fluid, it is almost impossible to develop a finite element model due to the necessity of the fine meshing of the plate and the fluid at the same time. This necessitates the use of solid plate with equivalent material properties. Unfortunately the effective elastic constants suggested by the ASME code are found to be not valid for the modal analysis. Therefore in this study the equivalent material properties of perforated plate are suggested by performing several finite element analyses with respect to the ligament efficiencies.
