Emergence from anesthesia may be neurologically unsatisfactory. Delayed awakening after general anesthesia is most commonly caused by the effects of anesthetic drugs, but primary central neurologic events (hemorrhage, ischemia, and embolus, etc) that occur during surgery can cause failure to awaken. We experienced a patient whose emergence was delayed from general anesthesia for zygomatic bone savage. The patient had such unexpected focal neurologic abnormalities as left ankle clonus and anisocoria (right dilation). Brain CT revealed acute subdural hematoma as a cause of delayed emergence in the postanesthetic care unit. An emergency craniectomy was performed to evacuate the hematoma, but the patient failed to regain consciousness following surgery. The patient regained consciousness on the 28th postoperative day, and had left hemiparesis and right blindness. (Korean J Anesthesiol 2006; 51: 133~6)

투수성이 낮은 매질로 설치되는 차수벽(Cut-off wall)은 댐 지역 비상여수로 터널 지역에서 지하수의 흐름을 차단하기 위한 기능을 갖는다. 임하댐의 3개 비상여수로 터널 입구부에 차수벽 설치시 지하수 유입의 차단 효과를 평가하기 위하여 MODFLOW 모델링을 활용하였다. 규모와 설치 방향 등을 고려하여 3가지 차수벽 설치 방안이 검토되었는데, 모델링을 통하여 추정된 비상여수로 터널내로 유입되는 지하수량은 약 64.26~65.49 m3/day이며, 이중에서 차수벽 구간을 통과하여 유입되는 지하수량은 약 44.08~45.31 m3/day로서 방안별로 유사한 것으로 나타났다. 따라서, 본 연구지역에서는 방안별 차수효과보다는 시공성, 환경파괴의 최소성 등을 고려하여 최적의 차수벽 설치 방안을 제안하였다. Cut-off wall with a low permeability can be constructed to prevent groundwater seepage in spillway tunnel areas. Three spillway tunnels are constructed in Im-ha multipurpose dam region and three types of cut-off walls with a variety of directions and scales are designed. As a result of MODFLOW modeling to assess the effect of cut-off wall for three types, groundwater inflows to the tunnels range from 64.26 m3/day to 65.49 m3/day and also they through a cut-off wall section from a reservoir do from 44.08 m3/day to 45.31 m3/day and it does not show any significant difference among them. Therefore, a construction process and an environmental conservation rather than the effectiveness of cut-off wall need to be considered to select the best cut-off wall in this region.

An equation is developed to estimate potential groundwater resources available for development. This equation is useful for planning generally conducted prior to detailed design. The equation is a function of major factors such as aquifer characteristics, saltwater intrusion length, coastalgroundwater discharge and location of proposed pumping wells. Therefore, the equation is quite comprehensive. The equations are derived using well-known analytical solutions. Thus, the basis is scientifically sound. Use of the equation is quite simple since it is an explicit function of variables. A logical method is proposed to assess a radius of influence of a pumping well considering aquifer characteristics and pumping rate. Applications to a hypothetical problem and comparison with results from a more rigorous numerical simulation model indicatethat results obtained from the proposed equation are conservative.

Salmonella infection occurs in 5 different clinical forms; gasteroenteritis, enteric fever, bacteremia, chronic carrier state and localization at one or more sites. Extraintestinal pyogenic infections caused by salmonella species include soft tissue abscesses, bone and joint infections, cholecystitis, liver abscess and splenic abscess etc. Pancreatic abscess due to Salmonella typhi is a very rare extraintestinal manifestation of salmonellosis. Infection pathways may be considered as reflux of infected bile through the pancreatic duct, hematogenous spread from a distant site or lymphatic spread from the intestinal tract. Treatment of pancreatic abscess needs surgical intervention and antibiotics therapy. We have experienced a case of a 40-years-old female with pancreatic abscess due to Salmonella typhi. She was treated with ultrasonography-guided catheter drainage and intravenous ceftriaxone for 18 days. After 14 days, the sonographic examination revealed the abscess cavity in pancreas almost disappeared. We report this case with review of literatures.
