Based on the data obtained from field investigation and soil testing to slope hazards occurrence section and non-occurrence section in crystalline rocks like gneiss, granite, and so on, a prediction model was developed by the use of a decision tree model. The classification standard of the selected prediction model is composed of the slope angle, the coefficient of permeability and the void ratio in the order. The computer program, SHAPP ver. 1.0 for prediction of slope hazards around an important national facilities using GIS technique and the developed model. To prove the developed prediction model and the computer program, the field data surveyed from Jumunjin, Gangneung city were compared with the prediction result in the same site. As the result of comparison, the real occurrence location of slope hazards was similar to the predicted section. Through the continuous study, the accuracy about prediction result of slope hazards will be upgraded and the computer program will be commonly used in practical.

Objectives: To investigate the rate of postoperative urinary retention (POUR) and identify the risk factors for this complication in women who underwent transvaginal uterosacral suspension surgery. Methods: A retrospective chart review was conducted for 75 women who underwent transvaginal uterosacral suspension surgery with vaginal hysterectomy, repair of cystocele, and levator myorrhaphy with/without transobturator anti-incontinence surgery. POUR was defined as a need for continuous intermittent catheterization on the third day subsequent to removal of the urethral indwelling catheter. Results: Acute POUR was reported in 18 women (24.0%). Thirty-six of the 75 patients (48.0%) had undergone anti-incontinence surgery. Crude analysis revealed significant association between the following variables and the risk of POUR: hypertension, the lower average flow rate in the pressure-flow study (PFS), greater post-void residual (PVR) urine volume in PFS, and PVR >30% of the total bladder capacity (TBC) in PFS. In the logistic regression analysis, PVR >30% of the TBC in PFS was identified as the only significant predictor of POUR (odds ratio, 15.4; 95% confidence interval, 2.5-90.9; P = 0.003). Conclusions: The PVR >30% of the TBC in PFS was identified as the only predictive factor of acute POUR in women who underwent transvaginal uterosacral suspension surgery.

본 연구에서는 화강암, 편마암 등 결정질암 지역에서의 급경사지재해 발생지역 및 미발생지역에 대한 현장조사자료 및 토질시험자료를 토대로 의사결정나무모형을 이용한 급경사지재해 예측모델을 개발하였다. 선정된 급경사지재해 예측모델의 분리기준은 최상위부터 사면경사, 투수계수 및 간극비로 선정되었다. 그리고 이를 토대로 GIS기법을 이용한 국가 주요시설물 주변 급경사지 재해 예측프로그램 SHAPP ver 1.0을 개발하였다. 개발된 예측모델 및 예측프로그램을 검증하기 위하여 강릉시 주문진읍 일대의 현장조사결과와 대상현장에 대한 예측결과를 비교 검토하였다. 검토결과 실제 급경사지 재해가 발생된 구간과 급경사지재해 예측구간이 유사하게 일치하고 있는 것으로 나타났다. 추후 지속적인 연구를 통하여 급경사지재해 예측 결과에 대한 정확도를 높이고, 이를 실용화하여 범용적으로 사용이 가능하도록 할 예정이다.
