Effect of sub-maximal exercise load differences onthe change of blood glucose and lactate contents were investigated. The results were as follows: 1. Blood glucose is quite relative under exercise load intensity (THR 70%, 90%) right after exercise and at the stage of relaxation. 2. Blood lactate contents were the most immediately after the exercise. 3. Under exercise load (THR 90%), Blood glucose and lactate are less related with each other before and after the exercise; on the other hand, in a restoring stage the result was reverse. Therefore; the higher the exercise intensity is, the more blood lactate is comcentrated immediately after exercise and it talkes a lot longer to go back to the stage of before exercise: the research revealed.

Concentrated solution was prepared for a sol-gel process of BaTiO₃. Barium hydroxide and Ti-isopropoxide were used as the raw materials with methanol and isopropanol as solvents. Dense ferroelectric polycrystalline BaTiO₃thin films with the perovskite structure were fabricated by spin coating of the prepared concentrated solution on a few substrates. From XRD investigation, it was confirmed that tetragonal phase of polycrystalline BaTiO₃powders are formed after heat treatment above 550℃ in air and grain-oriented BaTiO₃thin films are obtained by coating of 0.06M concentrated solution on the substrates. It was observed that surfaces of thin films deposited on the substrates by our methods were formed crack-free and uniformly. The thickness of thin film which depends the concentration of the solution was 400∼900Å for 1 time coating, which was confirmed by SEM analysis. Ceramics and thin films show dielectric constant of 4600 (at 1㎑) and capacitance 300∼800㎊ (at 1㎑) at room temperature, respectively.

The Purpose of this study was to investigate the effect of exercise intensity on blood glucose and insulin levels in diabetic rats with alloxan. Twenty sprague-dawley male rats were assigned to power training groups(n=10) and endurance training groups(n=10). Diabetes was induced by single injection of alloxan(50 mg/kg B.W) Blood glucose and insulin were determined every week for 4-weeks. The conclusion of this study follows as below: 1) There was significantly different on blood glucose levels in two groups. 2) There was significantly different on insulin levels in two groups These results suggest that proper exercise intensity in diabetic rats can significantly decrease blood glucose and insulin level and make good glycemic control. In conclusion, it has been found that regular prolonged endurance training with diabetic rats, improves insulin and blood glucose.
