In this paper, we propose a compositional motion capture system to utilize sensor fusion technique to enhance the accuracy of measured motion data. As an experimental system, we designed a double pendulum system which is capable of 4-degree of freedom motion. Man data are acquired through a set of infrared stereo vision system while potentiometers are involved in each joint as reference data sensors. Each sensor data from stereo vision system are transformed to position data of the links in the pendulum system, and 3-dimensional OpenGL-based graphic systems are developed to visualize the real motion. Hereafter any sensor fusion technique may be applied to the developed system for improved accuracy of the motion capture even for human body.

This study was carried out to examine the useful components of Purs Lane and their nitrite scavenging effect. Leaves and stems were separated and analyzed fo general chemical composition, amino acid composition, and dietary fiber contents. Anti-oxidant nutrient such as total vitamin C, total phenol ice, and vitamin E contents were also analyzed. Nitrite scavenging effects of methanol extract and aqeous extract were examined.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

<P>Calcium channel blockers are widely used antihypertensive drugs, which are uncommonly associated with cutaneous reactions, such as pruritus, urticaria, or alopecia. Photosensitivity presenting with telangiectasia has rarely been described. We present here a case of photodistributed telangiectasia induced clinically by amlodipine and histologically by enlarged capillaries in the upper dermis without signs of vasculitis.</P>
