For the performance analysis of torque converter, one dimensional performance model, which is based on the concept of constant mean flow path and constant flow angle, has been used. The assumptions or constant parameters make the procedure of analysis and design simple. Because the constant parameters does not have exact physical meaning, the correction factors have been used in practise. But the correction factors also have not physical meaning. Therefore, the numerical modelling with variable parameters is needed to understand the contribution of parameters on the performance. In this study, the determination algorithm of variable equivalent parameters is presented for the analysis of the torus flow and the variable flow angle. To set the objective function of optimization, the torque converter was modeled in detail. The parameter determination algorithm is based on the nonlinear optimization and the initial values of parameters may be supplied. The geometric analysis was carried out and the effect of oil temperature was analyzed before optimization. Using the determined parameters, the torus flow and the behaviour of flow angle was predicted.

The purpose of this study was to find the effects of scapular pattern and hold-relax technique of propriocetive neuromuscular facilitation(PNF) on the range of motion(ROM) and to find the effects of pain relieve through visual analogue scale(VAS) in frozen shoulder patients. The subjects were consisted of thirty frozen shoulder patients(men ; 9, women ; 21). The measurement of the shoulder range of motion was taken by measuring the degrees of flexion, abduction, and external rotation with a goniometer and the measurement of pain was performed by VAS from pre treatment to one to four weeks The results were as follows : 1. There was the statistical significance not only in the range of motion such as shoulder flexion, abduction, and external rotation, but also in VAS during four weeks(p<.05). 2. By the result of Scheffe's multiple comparison test. there was statistical significance between the values of pre treatment and treatment after one week in the range of motion of shoulder flexion. In that of shoulder external rotation, there was statistical significance between the values of pre treatment and treatment after one week, and between those of treatment after one and two weeks. As the result of this statistical significance of shoulder external rotation, the early treatment was thought to be more effective. However, there was statistical significance in the treatment after two and three weeks in shoulder abduction and was statistical significance between the values of pre treatment and the treatment after one weeks, and between those of treatment after two and three weeks in VAS (p<.05). 3. There was not statistical significance between men and women in the range of motion of the shoulder and in VAS(p>.05). 4. There not statistical significance between th right and left frozen shoulder patients in the range of motion of shoulder and in VAS(p>.05).
