Kim Rip Shi Jib is the original text of Kim, Byeong-Yeon's(1807∼1863) collected poetry. The research about the original text of Kim Rip Sin Jib is based on Lee, Eungsoo's first, second, and final editions of which the title was changed into Satirist Kim, Satkat. The secondary texts that are used for the comparison with the main text are Kim Rip Sin Jib by Baek, Gilsoon, Park, Oyang and Chinese poetry written by Kim, Byeong-yeon and translated by Heo, Munsub, Keon, Yonghan, Kim, Yonghan, Lee, Myoungwoo which has the same contents as 『Kim Rip Shi Jib』 but only changed its title. Leaving the wrong words as unsolved led to serious mistranslation. Therefore, the wrong words handed down since Lee, Eungsoo should be thoroughly corrected. Questions can be raised about the authenticity of the poems in the collection given the problems mentioned above. Appropriate measures should be taken to solve the problem.

본 연구에서는 폴리머 콘크리트의 수축저감을 목적으로 수지량, 수축저감제함량과 S/a 비등을 변화시켜 경화수축의 변화와 강도 특성을 실험적으로 구명하였다. 경화수축량은 수치량이 105%일 때 보다 11.5%일 때, 즉 수지량이 증가할수록 커짐을 알 수 있었다. 수축저감제의 첨가에 따른 경화수축량은 감소함을 알 수 있었다. B10.5-SR10일 경우 수축저감제가 첨가되지 않았을 때 보다 약 30%, B10.5-SR20 일 경우 약 53%, B11.5-SR10일 경우 약 31%, B11.5-SR20 일 경우 약 47% 정도의 수축저감의 효과를 볼 수 있었다. S/a 비에 따른 경화 수축챨ㅇ은 S/a 60일 때 가장 적은 값을 보였으며, S/a 50, S/a 40 일때는 S/a60 일 때 가장 적은 값을 보였으며, S/a 50, S/a 40일 때는 S/a 60일 때 보다 각각 10%, 30% 정도 수축량이 증가함을 알 수 있었다. 압축 및 휨 강도특성은 수지량이 증가할수록 높아지고, 수축저감제의 첨가량이 증가할수록 낮아짐을 알 수 있었다. S/a 비에 따른 강도 특성은 압축강도와 휨강도 모두 S/a 비가 60일 때 가장 큰 값을 보였으며, S/a 비가 50,40 순으로 감소하였다. Many different polymer based concrete materials are known today, but the large setting or hardening shrinkage of polymer concrete is a problem to overcome in their practical applications. The setting shrinkage reaches about five to ten times the drying shrinkage of ordinary cement concrete, i.e, 50 to 60 ×10^4. This paper deals with a reduction in the hardening shrinkage of unsaturated polyester resin concrete which is treated with respect to shrinkage-reducing agent content, S/a ratio and catalyst content, and tested for length change during hardening, and flexural and compressive strengths. It is shown that the change of shrinkage-reducing agent content and S/a ration the length change of the unsaturated polyester resin concrete during hardening.

Suspended and dissolved substance were included in water. Suspended substances can be relatively easily removed by sand filter, whereas, complete removal of dissolved substances in water was not possible at present. It is due to repulsion between negative charge of dissolved substances and sand filter previously used. Potential application of sand filters coated with Al and Fe in removing humid substances was evaluated in this experiment to improve removal efficiency of the dissolved substances in the water. In the adsorption experiment, the removal efficiency of humic substances was higher in the coated sand filter than In the uncoated one. More specifically, the higher removal efficiency of the humic substances in the Al-coating sand filter was obtained over the pH range randomly determined(4.2, 5.1, 7.6, and 10.0). Especially, the removal efficiency of the humic substance at the pH 10 was relatively constantly maintained at a level of about 95% during the maximum 8 hours. After then, it was sharply decreased. In the leaching experiment, the concentration of leachate in both coated and uncoated sand filters was all the highest at pH 9.95. It was relatively higher over the pH range of 7 to 10 than other pH range. Finally, the removal efficiency of the humic substances obtained in the readsorption experiment was rapidly declined, compared to that obtained in the adsorption experiment. Experiment results acquired in this research may be used to develop a promising technology for the removal of bacteria, algae, and colorful colloids, and a variety of dissolved substances in water.

본 연구는 하수 종말 처리에 의해 발생되는 하수 슬러지를 잔 골재(경량골재)로 사용하여, 폴리머 콘크리트를 제조하여 그 때의 역학적 성질에 대하여 검토하였다. 하수 슬러지는 5일간 110±5℃에서 수분함량 0.1%미만으로 건조한 후 파쇄하여 No.4∼No. 200 번체의 잔골재 표준 시방서 기준에 부합되도록 사용하였다. Pellet는 보통 회전pan에서 만드나, 본 실험에서는 수동으로 제조하였다. 제조한 하수 슬러지 경량 골재는 평균 겉보기 비중은 1.58(g/㎤), 단위용적중량은 1.98(t/㎥)으로 KS F 2534의 경량골재의 절건비중과 단위용적에 따른 분류에 의하면 중위급(medium weight) 경량골재에 속하는 것으로 측정되었다. 또한 잔 골재 중 하수 슬러지 경량 골재를 0%, 5%, 10%, 15%, 20%, 25%, 30%로 치환하여 그때의 압축, 휨, 인장강도를 측정하였다. 그 결과 하수 슬러지의 증가에 따라 강도 감소를 보였으나, 일반 경량콘크리트 제조 또는 단열용 콘크리트 블록 제조에 사용이 가능하다고 사료된다. 그러므로 앞으로 건조수축, 크리이프 특성 및 내구성에 관한 연구가 더욱 심도 있게 이루어져야 폐자원인 하수 슬러지를 이용한 건자재의 개발이 가능하리라 판단된다. In this study, the polymer concrete was produced by using the lightweight aggregate that had been manufactured using the sewage sludge and its physical properties were experimentally examined. Experimental results show that when the portion of sewage sludge lightweight aggregate in the fine aggregate increases, slump values decreases. Also, the compressive, the flexural and the tensile strengths decrease when the portion of sewage sludge lightweight aggregate increases. Although its strengths decreases, the sewage sludge lightweight fine aggregates is thought to be used for construction materials.
