특징형상개념을 이용한 CNC선반용 CAD/CAM시스템 개발
조진문,김석일,서명원 한국항공대학교 1995 論文集 Vol.33 No.-
Most of CAD/CAM systems for CNC lathe have been developed as the form of automatic programming systems which can generate autormatically or interactively the NC code from the process sheets and design drawings of products. But these systems have some problems during the modeling process of product shap since the shape is not described by the features intimate with system users such as chamfering, rounding, groove, arc and so on. Therfore, in this paer, the feature based CAD/CAM system for CNC lathe which is able to represent the truned product shapes by the typical features, is developed. Especially the system has the various capabilities such as the automatic determination of cutting domains, the automatic generation of CL data and NCcode, the real time cutting simulation for verification of NC code, the DNC operation and so on.

N/A Objective : The aim of this study was to evaluate the efficacy of laparoscopic uterosacral nerve ablation (LUNA) in infertile women with chronic pelvic pain and endometriosis. Method : Prospective randomized study was performed in 20 infertile women with endometriosis and chronic pelvic pain, who had undergone of laparoscopic uterosacral nerve ablation at Samsung Cheil hospital between April and September, 1998. Statistical analysis was perfomed using by DBSTAT (ver. 2.0). Result : The pelvic pain score of pre-operation was 3.72±1.07 (mean±SD) and it was significantly decreased to 1.83±0.85 at 1 month later and 1.93±0.92, 1.69±0.60, 1.56±0.62, 1.56±0.81 each in second, third, fourth and fifth month after operation. There was no correlation between pelvic pain and stage of endometriosis. Pregnancy rate was 65% after LUNA (twelve deliveries, one pregnancy is ongoing at IUP 24 weeks). Conclusion : Laparoscopic uterosacral nerve ablation would be effective for infertile women with endometriosis and pelvic pain.
Case Reports : A case of pedunculated hepatic hemangioma mimicking submucosal tumor of the stomach

Hepatic hemangioma is the most common benign tumor of the liver. Most such hemangiomas are small, asymptomatic, and have an excellent prognosis. Giant hepatic hemangioma has been reported in the literature, but the exophytic and pedunculated forms of hepatic hemangioma are rare. A 56-year-old woman was referred to our hospital under the suspicion of having a gastric submucosal tumor. Abdominal computer tomography (CT) scans showed a pedunculated mass from the left lateral segment of the liver into the gastric fundus, exhibiting the atypical CT findings of hepatic hemangioma. We therefore decided to perform laparoscopic resection based on the symptoms, relatively large diameter, inability to exclude malignancy, and risk of rupture of the exophytic lesion. The pathology indicated it to be a cavernous hemangioma of the liver. Herein we report a case of pedunculated hepatic hemangioma mimicking a submucosal tumor of the stomach due to extrinsic compression of the gastric fundus.
