Nature to come out in KASA work is expressing abstract relations for a writer whom he does not remind so much on the appearances of nature as on his psychological attitude. KASA is the language of the imagination and the passion. It relates to whatever gives immediate pleasure or pain to the human mind. In my opinion, this mental substitute reject of human desire, its imagination, its sensibility, its satisfaction, as a whole, is to sooth the mind with illusions. The work of poetry, I decide, was the crowning product of human activity, and the final justification for all the misery the endless toil and the frustrated striving of humanity. Each art has its own medium ; the painter his pigments, the musician his sounds, and the writer, his words. The world may, broadly speaking, be a vale of tears, but could we know all the vicissitudes of our fortunes, life would be too full of hope and fear, exultation or disappointment, to afford us a single hour of true serenity. Our nature it was the most wonderful landscape that the imagination of man could conceive. The thick vegetation met overhead interlacing into a natural pergola and twilight flowed the green, pellucid river, beautiful in itself ; for where the thoughts and the heart are, there is our true existence. The beauty of the world and the interesting thing in nature are there for every work of KASA. The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead ; his eyes are closed. This instigh into the mystery of life has also given rise to religion that is beauty of oriental and Buddist confuscious philosophy. The course of emotional experience differs very little from age to age, and from individual to individual, and so the same phrases may be used quite sincerely and naturally as the direct expression of feeling at its highest point by men apart in country, circumstance, or time. The deep feeling for nature which is one of the most marked characteristics of our Korea history as a whole is evidently in large measure the product of a changing Timespirit working more or less uniformly on many different minds and tending at this point to bring them into a certain substantial harmony with one another. Our poetry is a special way of using words in order to create a traditional our country in sadness and calmness.

This study examined the effect of environmental variables, such as the NaOH concentration and solution temperature, on the rate of hydrogen generation from NaOH solutions through the corrosion of used aluminum cans as a potential candidate material for the safe and economic production of hydrogen. Corrosion of the used aluminum cans was promoted by increasing the NaOH concentration and solution temperature because of the loss of aluminum passivity. The measured rate of hydrogen generation from the NaOH solutions increased with increasing NaOH concentration due to the catalytic activity of NaOH in the hydrolysis process. However, at higher solution temperatures, the rate of hydrogen generation rate was less affected by the NaOH concentration than that at lower temperature.

We studied the corrosion and oxidation properties of Fe-18Cr-0.4Nb-(0.1~0.6)Ti-(1~3)Si-(0.5~2)Mo stainless steel. The resistance to general and pitting corrosion was evaluated and the results were analyzed by Response Surface Methodology (RSM) as a function of alloy composition. The effects of alloy composition and heat treatment on the oxidation resistance were also examined. Mo increased both general corrosion resistance and pitting corrosion resistance. Si improved the resistance of the alloys to pitting corrosion. Si was also beneficial for general corrosion resistance of the alloys containing Mo at more than 1 wt.%. However, Mo was detrimental when its content was lower. Effects of Ti on general corrosion properties appeared to be weak and a high concentration of Ti appeared to deteriorate pitting resistance. The thickness of the oxidation scale increased and adhesion of the scale worsened as the temperature increased from 800℃ to 900℃. Weight gain of the alloys due to oxidation at 900℃ clearly showed that the resistance to oxidation is improved by annealing at 860℃ and an increase of Si content.
