항공사진촬영은 계획된 노선을 따라 항공기를 조정하여 적절한 위치에서 촬영을 수행하는 작업이다. 특히 3차원 공간데이터 구축을 위하여 사용되는 다각사진촬영시스템의 경우 대형 CCD가 중형 CCD를 사용함으로써 촬영면적이 크지 않아서 적절한 위치에서 촬영이 이루어지지 않는 경우 충분한 중복도를 확보하지 못하여 외부표정요소 결정에 문제가 발생할 소지가 있다. 따라서, GPS/INS를 이용하여 정확한 항공기의 위치를 결정하여 사전에 계획된 위치에서 촬영을 실시함으로써, 정확한 3차원 공간데이터의 모델링을 수행할 수 있다. The Aerial photographic mission is working of taking picture at appropriate point at operating aircraft. Specially, because multi-looking camera system for 3D spatial data construction don"t use large size CCD camera, do use middle size or small size CCD camera, Exterior parameter can"t be calculated because of not enough overlap, if taking picture at inappropriate position. Therefore, we can construct 3D spatial modeling data by taking picture at planned points using GPS Positioning information.
보중익기탕(補中益氣湯), 소음인(少陰人) 보중익기탕(補中益氣湯)과 그 구성약물군(構成藥物群)이 alloxan으로 유발(誘發)된 고혈당(高血糖) 백서(白鼠)에 미치는 영향(影響)

The purpose of this study was to investigate the effect of Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) and its component groups on diabetes in alloxan induced diabetic rats. Sprague-Dawley male rats weighing $200{\pm}10\;gm$ were randomly assigned to one normal, one control and five experimental groups. The experimental groups was classified into to Bojungikgitang(B1 group), Soeumin bojungikgitang(B2 group), Bogihyulyak(B0 group), Siho-sengma(B1+ group) and Gwakhyang- soyeup(B2+ group). Diabetes was experimentally induced by abdomenal injection of 100 mg/kg of body weight of alloxan. Animals were sacrificed at the 6th day and 11th day of diabetic states. The results were obtained as follows: In carbohydrate metabolism, the level of glucose in control group was three-fold higher after alloxan injection than that of normal group. In B1, B2 groups the level of glucose was decreased by 39% and 43% compared with that of control group, and in component groups it was decreased by 73%, 81%, and 80% respectively. In fat metabolism, the level of triglyceride and total cholesterol in serum were lower in B1 and B2 groups with high significant difference and had similar tendency in components groups compared with that of control group. The level of HDL cholesterol on serum were increased in B1 and B2 group with significant difference. And in component group it had similar tendency compared with that of control group. In protein metabolism, the level of total protein and albumin were higher in B1 and B2 group with significant difference, and in component group also increased but with no significancy compared with control group. In kidney function, the level of creatinine group with significant difference, and other compared with control group. In liver function, the level of GOT, GPT, ${\gamma}$-GTP. ALP and bilirubin were lower in B1 and B2 group with significant difference, and in component had similar tendency compared with control group. But in the level of LDH, it was decreased with no significancy. These results indicate that Bojungikgitang(補中益氣湯), Soeumin bojungikgitang(少陰人 補中益氣湯) has strong effect on diabetes and it is useful to prevent diabetes, and in component groups the difference between B1+ and B2+ group was not significant.

The purpose of this study was to reseach the effect of Daesihotang and its component groups on diabetes, free radical and antioxidative defense system in alloxan-induced diabetic rats. The experimental group was divided into three groups: Daesihotang (DS), Soyangyak (DS1), Yangmyungyak (DS2). The results were obtained as follows: The level of glucose, triglyceride, total cholesterol, creatinine in serum were considerablely reduced by Daesihotang. And the level of HDL cholesterol, albumin, total protein in serum were increased by Daesihotang significantly. And the level of BUN has some decreased, but with no significancy. In the study of Daesihotang on free radical scavenging effect in vitro, it has shown that Daesihotang and its components group have significant suppressing effect on peroxidation of linoleic acid on concentration. And in other experiments as scavenging effect of DPPH radical, inhibitory effect of superoxide in xanthine-xanthine oxidase system and inhibitory effect on lipid peroxidation reaction by hydroxy radical in $H_2O_2-Fe^{2+}$ system, Daesihatang have some activity, but with no significancy. In the study of Daesihotang on antioxidative defense system in vivo, the activity of GOT and GPT in serum were significantly increased; and the amounts of lipid peroxide in serum was reduced significantly but in liver no significancy. In hepatic catalase activity, Daesihotang has showed significant effect. In the level of hepatic glutathione, Daesihotang increased the amount of glutathione significantly. And in the activity of glutathione-s-transferase, Daesihotang has decreasing effect but has no significancy. These result suggest that Daesihotang has strong effect on diabetes and it is useful to prevent diabetes, but has less effect on peroxidative damage by free radical.
