In order to evaluate the effect of matric suction on the strength and deformation characteristics, the unsaturated unconfined compression test is performed for the statically compacted silty sand. Specimens used were made under conditions with various initial degrees of saturation. The initial matric suction, matric suction at the peak shear strength and the volumetric deformation during the shear process were measured. From these results, it was found that the initial degree of saturation exerts the influence on the behaviors of suction, peak shear strength and the volumetric deformation. Furthermore, the suction stress() which means the apparent cohesion due to matric suction in the unsaturated shear strength could be derived.

In order to examine the unsaturated shear strength characteristics of compacted weathered gneiss soils, the constant water content compression (CWCC) test was carried out. Specimens were made by static compaction under two densities conditions. The shear behavior in accordance with an initial suction obtained by varying initial degrees of saturation was evaluated. The suction could be directly measured by the use of the ceramic disk and the pore-water pressure transducer. The results of the peak shear strength from the CWCC test were examined using the relationship with Mp line from triaxial test under the saturated state, that is, by means of the suction stress which was calculated using the measured suction. In addition, the applicability of the suctions stress to the unsaturated shear behaviour of compacted weathered gneiss soils was discussed by applying Suction stress-SWCC Method (SSM).

본원 산부인과에서 최근자궁근종에서 발생된 자궁평활근육종을 경험하였으며, 이에 보조항 암요법 및 second look operation을 시행한 결과 complete remission 되었음을 확인하였고, 1 년 6개월동안 재발없이 생존하엿기에 문헌고찰과 함께 보고하는 바이다. A case of leiomyosarcoma was recently experienced in a 37-year old woman and is reported with brief review of literatures. The patients was received with eight coursed of adjuvant chemotherapy after operation and has followed for 1 1/2(one and half) year without evidence of recurrence. Uterine sarcomas are relatively rare tumors of mesodermal origin. They are the most malignant of all uterine tumors and present intriguing problems in regard to diagnosis, clinical behavior, pattern of spread and management.
