본 연구는 청동기시대에 제작된 것으로 추정되는 반구대암각화의 보존방안으로서 반구대 전면 하도구간의 수위조절을 통한 침수방지안이 적용될 경우 수위변화가 암벽면에 미치는 수리적인 영향을 수리모형실험을 통해 평가하였다. 저수지와 하천의 흐름특성을 고려할 수 있는 수리모형을 1:50 축척으로 제작하고, 수리모형실험 및 수치모의와 함께 암벽면에서의 수리특성의 변화를 분석하기 위한 압력측정을 병행하였다. 연구결과, 사연댐의 수위조절 시 침수시간은 감소하지만 침수를 방지하지는 못하는 것으로 나타났다. 홍수 시 최대유속은 10년~80년 홍수에서 발생하여 홍수량에 비례하지는 않았으며, 반구대암각화 전면에서의 유속증가량은 200년 빈도 시 약 425%, 2년 빈도 시 약 666%로 수위조절 시 홍수기의 암벽면의 훼손이 증가할 가능성이 있으므로, 이에 대한 대안 수립이 필요하다고 판단된다. If water level control will be executed in order to prevent the inundation for preservation of Bangudae petroglyphs, the assessment of hydraulic characteristic on rock sides was carried out with hydraulic model experiments. Hydraulic model was constructed by 1:50 scale to be applicable to flow characteristic of both stream and reservoir. Furthermore, this study was conducted to numerical simulation and pressure measurement on the surface of petroglyphs model at the same time. As results from this study, inundation time was clearly reduced but inundation prevention was barely occurred. Maximum mean velocity at the front of Bangudae petroglyphs was measured from 10 years to 80 years frequency flood event and not proportional to the frequency. Increasement of mean velocity was about 425% for 200 year frequency flood and about 666% for 2 year frequency flood compared to current condition. If water level control would be adjusted, potential damages of Bangudae petroglyphs would be likely to increase in flooding seasons, which should be requested for alternative prevention plan.

This study was subjectived elementary school books published between 1989 and 1991. There focused on the oriental medicine of all Health-Medical contents. The results of analysis for elementary school books were much less oriental medicine contents than the others.Also,it was negative trend in many contents like incorrect of historical incidence etc.That contents was not two medicine's complementarity but two division. This result did possible contribute to misunderstand and negative action toward oriental medicine in the elder age attitude. Oriental Medicine has been successive to the present and shall be continue to the future as natural korea culture. In order to continuity of normal Health-Medical culture and obtain of worldwide oriental medicine trend, it need to revise contents of elementary school books rapidly.
