최근에 개발된 나노 충전제를 microhybrid 복합레진에 첨가할 때, 나노 충전제 함량이 중합에 미치는 영향을 조사하기 위해, 실험적으로 나노 충전제의 함량을 다르게 제작한 복합레진에서 광중합 후 미세경도를 측정, 분석하여 다음과 같은 결론을 얻었다. 1. 나노 충전제의 함량이 2%, 3%인 군은 0%, 1%인 군에 비해 중합된 면의 미세경도가 유의하게 높았으나(p<0.01), 그 차이는 크지 않았다. 2. 나노 충전제의 함량이 높을수록 레진 시편의 하면에서의 미세경도는 증가하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). 3. 레진 시편의 상면과 하면의 미세 경도 차이는 나노 충전제 함량이 높을수록 감소하였으며, 나노 충전제의 함량이 0%, 1%, 2%간에, 0%, 1%, 3%간에 유의한 차이가 있었고(p<0.01), 2%와 3%간에는 차이가 없었다(p<0.05). The objective of this study was to evaluate the effects of nanofiller content on the microhardness and polymerization of experimental microhybrid composites. The nanofiller contents in the experimental composites were varied (0%, 1%, 2%, 3%), while the total filler content remained constant as 76 %wt. We obtained the following results: 1. The microhardness of the top surface for the 2%, 3% nanofilled microhybrid composites were significantly higher than those for the 0%, 1% nanofilled composites (p<0.05), but the difference was not great. 2. The microhardness of the bottom surfaces significantly increased with an increase in the nanofiller level (p<0.05), except between the 2% and 3% nanofilled groups (p>0.05). 3. As the nanofiller level increased, the difference beween microhardness of top and bottom surfaces significantly decreased (p<0.05), except between 2% and 3% nanofilled groups (p>0.05).

鄭哲正,孫泰烈,趙顯喆 成均館大學校 科學技術硏究所 1985 論文集 Vol.36 No.1

Integrated electrical activity(IEMG) from the tibialis anterior muscle and acceleration and ECG were simultaneously measured by two subjects during the walking performed on a treadmill set at 3km /h to 8km/h. Within the range of steady states measured, where no mounting fatigue was likely, both IEMG and HR, Acceleration were linearly related to the walking speed by the subjects. The mean liner correlation coefficient for the IEMG/Walking speed relationship was generally above 0.99 as were those for both the HR/W. Speed relationship and Accl./W.Speed relation-ship. Also the vertical accelerator(Av) of centers of gravity of the body in human walking was directly proportional to the walking speed untill 7km/h. But the Av. at 8km/h was changed to lange especially and that speed (8km/h) was guessed to limit of the normal walking pattern. It appears for heart rate to increase progressibly with along the walking speed, and until 7km/h nomal walking patterns can be possible, but after that time, Such a nomal walking pattern can be impossible and fast increasing result was reasonable at 7-8km/h, because a high heart rate lowers the mechanical efficiency of the heart and increases the oxygen uptake for a given cardiac output.

The aim of this study is to examine the effect oF meditation training on the respiratory and electromyography pattern in snatch of weight lifting. The meditation trainings were performed for 30minutes a day for 8 weeks to the experimental group of 6 players and the control group of 6 players after selecting 12 colege players. The reslt are as follows: 1. In the variation of the respiratory pattern in snatching the respiratory frequency was varied only in the experimental group in the 70-80% around the training and nowhere else. In the comparison of the groups, it was not significant difference before training the significant difference(P<.05) after training. The respiratory ratio was not changed by the meditation training and was not varied in the groups. 2. In the snatching 70-80%max,the turn of acting way of the main muscle through the electromyography is as follows : the biceps brachii, the deltoid, the latissimus dorsi, the vastus lateralis, the gastrocnemius. There was not significant difference in the acting way of muscle between before and after training. In the results above, it could be considered that meditation training was decreased the respiratory frequency and improved on the respiratory control capacity through the stability and the brought stability in the acting way of the electromyography. The psychological training through the meditation training has thus showed the possibility of using the physiological estimation method and application an events.

Spent pig bone was consist of hydroxyapatite. And then we thought that it have a possibility as a adsorbent. The preparation of bone char prepared from spent pig bone in this study. We study on the recycling possibility as a adsorbent is able to adsorb copper ion from their single aqueous solutions. The results are summarized as follows. Bone char that prepared from spent pig bone at 105, 400, 700℃. The adsorption removal efficiency of copper ion onto bone char as adsorbent was above 90% for 15 hours. Increase in the initial pH of the copper ion solution result in an increase in the copper ion uptake per unit weight of the adsorbent. Freundlich isotherm model was found to be applicable for the experiment data of copper ion. The results showed that spent pig bone can be used for the absorption of the copper ion.
