Objective : This study was carried out to examine the effect of Silbi-um(Shipi-yin, SBU) on obesity and antioxidation.Methods and Materials : SBU was investigated effects of obesity and antioxidation for DPPH radical ability, nitrate reductase activity, total body weight and fed ratio, serum glucose content, serum triglyceride and total cholesterol content, serum GPT and GOT content, serum leptin content, catalase activity, superoxide dismutase activity, lipidperoxidation and glutathione activity. In this experiment rats were divided into 4 group, Lean control; non-treated, Lean A; SBU, Fat; control: non treated, Fat A; SBU, Each value is the mean ± S.E for 3 separate experiments. Result and Conclusions : In vitro, DPPH radical ability and nitrate reductase activity were increased according to the increasing of SBU concentrations. In vivo, compared with Fat control group, the serum glucose content, the serum triglyceride content, the serum total cholesterol content the serum GPT and the serum GOT content were decreased in Fat A group. The serum leptin content was increased, too. Catalase activity and superoxide dismutase activity were increased and lipidperoxidation was decreased in Fat A group compared with Fat control group. Glutathione activity was not increased significantly. According to the above results, the obesity and the antioxidant activities of SBU were proved in experiment and it should be studied and developed more throughly.

Objective : The purpose of thesis is to establish oriental medical nutrition for medical treatment. Methods : We researched the nutritional theory and treatment about medicine, oriental medicine and chinese traditional food(Yaksun) in the literature. Results and Conclusions : summarized as follows 1. Oriental medical nutrition is same basic theory with herbalogy(Boncho) and should establish a part of oriental medicine. 2. The study about oriental medical analysis and application of that is needed because the nutritional factor and calory is also important to the healthy. 3. It is needed the study of composition of food list that applicate practical preventing and treatment as well as the efficacy of herb one by one for the establishment of oriental medical nutrition.

The purpose of this study is to correct the errors that may occur because of the patients' movement during the CT scanning, and thus, to obtain more precise CT images, additionally to investigate the possible use of parallel Beam CT in the dental treatment. Materials and Methods: Applying the Radon transform using phantom image, the same image and the sinogram with the ones by CT scanning were obtained. The possible movement errors that patients may cause during the CT scan were given to the data images. The maximum width of errors was designed to reach 1 mm. The fixed point was identified in the errored CT projected images, and each projected image with errors was adjusted so that each fixed point is placed on the same axial plane, then the fixed point was traced on the sinogram. On the traced trajectory of the fixed point, the part deviated from the sinusoidal curve was modified using the Virtual Alignment Method. Results: The quality of reconstructed image was remarkably degraded when the movement errors were given. The movement errors were corrected by moving the fixed point to the center of sinogram and this relocation of fixed point did not cause any distortion of image or change of size. Conclusion: The movement errors during CT scanning were corrected using the fixed point inside of the image. The more precise CT images obtained through this method are expected to be of extensive application in the area of dental implantology.
