The purpose of this study is to examine the raising of strength of concrete and workability using casting foundry fly ash. First, we conducted analysis of chemical components of fly ash. Then, we tested uniaxial strength of concrete at ages of 3, 7, and 28 days. As a result, we found that the strength of concrete using casting foundry fly ash is raisen up 16% than plain concrete when the fly ash is added 0.6% of weight of cement.

The reinforcement method for reducing fever prescribe sweet and warm drugs for reinforcing the middle heater and raising Yang(陽) and sweet and cold drugs for purging the pathogenic fire. Bojung-ikgitang(補中益氣湯) is representative prescription based on the reinforcement method for reducing fever. Therefore it is ought to be regarded as prescription for syndromes to show the impairment of Gi(氣), blood, fluids, and humors for pathogenic fire.

양액재배시 배양액의 pH는 중요한 재배인자이며, 이는 용수의 성질에 따라 큰 영향을 받는다. 용수로는 지하수를 많이 사용하나, 수돗물을 사용하는 경우도 흔히 있다. 수돗물은 pH가 7.5 정도로, pH가 낮은 용수를 사용할 경우와 같은 조성의 배양액을 조제하면 배양액의 pH가 높아 생육에 나쁜 영향을 끼친다. 따라서, 용수의 성질에 따라 배양액의 조성을 달리하여 pH를 적정수준으로 유지하는 것이 중요하다. (중략)

A new photochromic spiroxazine dye having a pyridinium s-triazine moiety has been prepared. It shows a reversible photochemical color change from colorless to reddish-purple in ethanol solution. In ethanol solution the half life time of the open form was 150sec, which was shortened by raising temperature. Silica-immobilized spiroxazine(6). Fine power of silica-immobilized spiroxazine was changed intensely blue from colorless by U.V. light or sunlight.
