Purpose: The purpose of this study was to investigate whether Qihyul-therapy was effective against subjects of bad Qihyul circulation who had narrowed muscles of the buttocks, a distorted body shape, or pain. Methods: Qihyul-therapy used. Results: The muscles of the buttocks remained almost untouched. The elasticity of the muscles restored. The skin tone brightened, and the anal muscle strengthened after Qihyul-therapy. The subject's body was shifted to the right by -7°. The right arm was about 6 cm longer than the left arm. But after correction, the right arm was about 5 cm shorter. The distorted body was almost balanced. After neck and shoulder correction, the distance between the collarbone and neck was 7~10 cm wider. After the pelvic correction, the pain in the buttocks was relieved, and the position of the hip joint returned correctly. The right leg that was turned 45° to the left was corrected, and the length became the same. Subjects had no knees attached, their right knees were up 5 cm above the left, and their ankles bent at an angle of 30 ° relative to the left, but after correction, the knees of the two legs stably attached. The height of the knee became the normal angle. Conclusion: If the Qihyul-therapy, the spine correction Qihyul-exercise and the pelvic correction Qihyul-exercise performed steadily, the deformed body shape restored adequately, and it is useful to prevent and cure related diseases by alleviating the pains.

본 논문은 산업현장의 불균등한 조명 조건에서 정확한 카메라 교정을 수행할 수 있는 방법을 제안한다. 비접촉 계측을 위한 카메라 교정법은 패턴에서 교정점들을 정확하게 추출할 수 있어야 하며, 평면 패턴을 사용하는 교정 방법은 최소 7개의 교정점을 알아야 한다. 그러나 비접촉 치수 계측기가 설치된 산업현장에서 카메라 교정에 알맞은 조명을 기대하기 힘들다. 본 논문에서는 최적조명제어가 어려운 산업현장에서 치수계측을 위한 카메라 교정을 효과적으로 수행할 수 있는 반자동 카메라 교정방법을 제안한다. 교정패턴상의 최소 4점을 사용자가 지정함에 의해, 조명제어의 어려움으로 인해 교정점 추출이 실패한 교정패턴의 불완전 교정점을 사용하여 이상적인 조명상태에서의 교정점 정보를 예측하고, 이 정보로부터 다시 정확한 교정인자들을 반복적으로 추출하는 방법을 적용한다. 제시된 방법은 렌즈의 투사왜곡에 의한 교정패턴에서도 성공적으로 적용될 수 있음을 실험을 통해 확인하였다.

The characteristic and efficiency of natural shell sand in the coast of Cheju-Do and Jin-Do were studied to apply as agricultural lime for the soil acid adjustment. 1. The alkalinity of shell sand from Cheju coast was higher than that of Jindo and more weathered into fine particles. The particle size distributions of Cheju shell sand were condensed finer particles than 32 mesh in Cheju shell sands and in more coarser particles than 32 mesh in Jindo one. 2. The effect of Cheju shell sand on increasing soil pH value in the upland condition was low at the beginning but more gradually increased after 8 weeks from the treatment than ground lime, and Jindo was very dull during the period of treatment. The commercial lime crushed from Jindo was approximately equal to the ground lime. 3. In the submerged condition, the shell sand of Cheju reacted with soil acid more quickly than ground lime after 2 days, and Jindo was very slow. 4. The relative efficiency of various particle size fraction of the shell sand was superior to the ground lime. The lime particles between 9 to 14 mesh and 20 mesh had more remarkable difference of pH value than other fine particles. The efficiency among finer sizes than 20 mesh particle was approximately equal to each others. 5. The shell sand from the Cheju would be applied directly as agricultural lime without any treatment, and Jindo also can be expected to be effective as agricultural lime with crushing procedure.
