  • This dissertation analyzes the running mechanism of flexible and thin tape above rotating head through the numerical simulation and the experiment. The scope of analysis is confined to the phenomena of two dimensional elasto hydrodynamic lubrication between the protruded bump on a rotating cylinder and the running tape. This model is based on the elastic deformation equation of plate and shell and Reynolds equation. Finite difference method is employed as a numerical technique to calculate (1) the distribution of pressure between the running tape and rotating bump and (2) the vertical deformation of elastic thin tape over he rotating bump under hydrodynamic pressure. In numerical analyses, the effects of bump size on flying characteristics of the tape were evaluated and examined considering the influence of tension and stiffness of tape.

  • PURPOSE: The purpose of this study was to investigate the effect of taping method using elastic tape and non-elastic tape on pain, grip strength and muscle activity in middle-aged female patients with lateral epicondylitis. METHODS: The subjects were 40- to 50-year-old female patients with lateral epicondylitis. A total of 22 subjects were divided into two groups, and each group had 11 patients. The intervention was carried out three times a week for 4 weeks. One group applied tape using elastic tape (ETG) while the other group applied tape using non-elastic tape (NETG). The measurement factors were pain, grip strength, and muscle activity. Pain was measured using VAS. Grip strength was measured using a grip dynamometer, and muscle activity was measured using EMG in the affected extensor carpi radialis brevis. Changes in interventions were compared among the groups using a paired t-test. The comparison between groups compared delta values (Changed values) between pre- and post-intervention using an independent t-test. RESULTS: In both groups, there was a statistically significant decrease in VAS. However, there was no statistically significant decrease in the delta value of VAS between ETG and NETG. In both groups, grip strength and muscle activity increased after intervention. There were statistically significant differences in delta values between ETG and NETG. CONCLUSION: Taping is a good intervention method for patients with lateral epicondylitis. Both elastic tape and non-elastic tape were effective. In particular, taping using elastic tape is an effective method for improving muscle function with pain reduction.

  • The main issues for the power application of high Tc superconducting tape are lower AC loss and higher stability conditions. HTS tape has large stability margin by high heat capacity of superconductor itself and high temperature margin. But, it can be damaged by continuous heat generation at quench point, because normal zone propagation velocity by generating heat is very low. Here, we analyze the quench propagation characteristics using finite element method for BSCCO-2223 HTS tape.

  • we evaluated the effects of joining process such as contact method. shape of joined area and pressure on the electrical and mechanical properties of Bi-2223 superconducting tape, Specifically. the current capacity of the jointed tape was measured as a function of uniaxial pressure. and the thermal shock, bonding strength and the thermal of the tape were evaluated and correlated to the microstructural evolution. It was observed that the current capacity was significanrly dependent on the uniaxial pressure The jointed tape, fabricated with a pressure of 1,000-1,600 Mpa. showed the highest value of current capacity results from improvements in core density, contacting area and grain alignment, ect. In addition, the strength of jointed tape was measured to be 86 Mpa, which is about 88% of the unjoined ape's strength. The irreversible strain($\varepsilon$irrev) for the jointed tape was measured to be 0.1%, smaller than that of unjoined tape ($\varepsilon$irrev= 0.3%). The decrease in the strength and irreversible strain for jointed tape is believed to be due to the irregular geometry/morphology of the transition area of the tape.

  • Purpose: This study aims to examine whether the kinesio tape method can relax perimenstrual symptoms and decrease the menstrual pain of those who complain of perimenstrual discomforts. Method: This study has been designed to use the nonequivalent control group in the pre and post-test. The data have been collected from unmarried females complaining of perimenstrual discomfort and living in D city from the 2nd of February through the 10th of April, 2002. An experimental group of 32 people and a control group of 35 people were chosen, and they were first investigated for symptoms before and after menstruation when the menstrual pain was the severest and for the VAS measurement of menstrual pain. For the experimental group, the kinesio tape method was conducted two times a week for three weeks (six times in all), and the control group remained intact. The investigations after the experimental treatment were carried out in the same way as before. The measuring instruments were the peri menstrual measuring instruments of symptoms of 42 items and the menstrual pain was measured by VAS Result: The primary hypothesis: The experimental group who used the kinesio tape method would experience less perimenstrual discomfort than the control group who did not use it. The first sub-hypothesis: The first sub-hypothesis that suggests 'The experimental group who used the kinesio tape method would experience more relaxation of perimenstrual symptom than the control group who did not use it' was supported. The second sub-hypothesis: The second sub-hypothesis that suggests that 'The experimental group who used the kinesio tape method would get lower scores of menstrual pain of VAS than the control group who did not use it' was supported. Conclusion: These results of the study show that the kinesio tape method is effective in relaxing perimenstrual symptoms and lessening menstrual pain.

  • The purpose of this paper is to in vestigate a relative effectiveness of instruction among such three orienting methods as lecture, slide-tape and video-tape which the library of Duk Sung Women's University has applied for orienting the freshmen for the last three years. This research also carried out a sample survey by distributing uniform questinnaire to the three different groups of the students. Each group was oriented with lecture, slide-tape and Video-tape respectively. Finally, the empirical findings of this research are as follows: 1. All three orienting methods were useful for students to improve knowledge as to how to use the library, 2. There were a wide difference in effectiveness among three instructional methods, obviously, the slide-tape method was more effective in the orientation than the lecture method and, furthermore, the video-tape was more effective than the slide-tape one, Therefore, it seem safe to conclude that the media utilization effective in orientation program should be encouraged by the university libraries of Korea.

  • Background: Radio-telemetry is a useful method to investigate the spatial ecology of species in the wild, by tracking the signal of a transmitter attached to an individual. The method of attaching a transmitter to a snake is representatively divided into surgical implantation, and external attachment, which latter is often used in small snake species. Results: In this study, we evaluated and compared the utility of two external attachment methods, the nylon thread method and the tape method, applied to a small grassland snake species of approximately 50 cm snout-vent length, the Slender racer (Orientocoluber spinalis), on an island in the Republic of Korea. The nylon thread method and the tape method were applied to four and five individuals, and radio-tracked for an average of eight and eleven days, respectively. The nylon thread method caused individual injury and disturbed their movement, while using the tape method, the transmitter package sometimes dropped off, but no injury or movement problems occurred. Conclusions: Considering that poor understanding of how to attach the transmitter makes it difficult to investigate the spatial ecology of small snake species, the tape method, evaluated in this study, could be applied to attach a transmitter and to study spatial ecology of such snakes.

  • The longitudinal vibration of the tape in the tape transport system influences the performance of the nagnetic tape-recording system. Generally it is controlled by a passive method with impedance roller which is easy to implement and cost-effective. Therefore the effect of the impedance roller in reducing the tape vibration was analyzed in this paper. The practical tape transport system was modelled mathematically as a mass-spring system. Both simulation and experimental study were carried out in order to show the vibration reduction effect of the impedance roller.
