Background/Aims: Up-to-seven criteria was proven to be useful for predicting prognosis after liver transplantation in patients with hepatocellular carcinoma (HCC). The aim of this study was to evaluate that up-to-seven score could be useful method for prediction of prognosis in patients with HCC who did not undergo liver transplantation. Methods: Between January 2006 and December 2008, 216 HCC patients without vascular invasion, lymph node and distant metastasis were analyzed retrospectively. We investigated the prognostic impact of laboratory findings, clinical characteristics, modified UICC T stage, and up-to-seven score in HCC. The survival analyses were performed using Kaplan-Meier Results: Two-hundred sixteen patients with HCC were included. Age was 60.1±11.3 years and 74.5% were male. Chronic hepatitis B was the most common cause of liver disease (60.6%). T stage was T1, T2, and T3 in 36 (16.7%), 118 (54.6%), and 62 (28.7%) patients, respectively. Up-to-even score was 5.5±4.0 and it was <3 (UTS 1), ≥3 and ≤7 (UTS 2), and >7 (UTS 3) in 36 (16.7%), 133 (61.6%), and 47 (21.8%) patients, respectively. The 10 (8.5%) patients of T2 stage were classified into UTS 3 and 25 (40.3%) patients of T3 stage were classified into UTS 2. The prognosis was significantly different in patients with T2 or T3 according to their UTS. Multivariate analysis showed that Child-Pugh score and UTS were significantly associated Conclusions: Up-to-seven score was useful to predict prognosis and to evaluate tumor stage in patients without vascular invasion, lymph node and distant metastasis.

Head impact performance is the one of the safety regulation in FMVSS 201, Domestic safety standard 88, ECE 21. The main contents of this regulation is that deceleration shall not exceed 80g continuously for more than 3 milliseconds to pass the test and interior compartment doors shall not open. Lately, interior compartment doors are designed on the center fascia of the crash pad to satisfy customer's convenience. So there are many problems that interior compartment door is open during the test in the last stage of the car development In this study we have tried to search optimum design spec of latch system and to set up the analysis technique to satisfy Head Impact regulation by using FEM simulation and DFSS technique in the early stage of car development.

저자들은 심와부 동통과 황달을 주소로 내원한 40세 여자에서 단순촬영 및 복부전산화단층촬영을 통해 석회쓸개즙을 진단하였으며, 내시경역행췌담관조영술을 통하여 폐쇄황달을 유발한 담낭관 및 총담관의 석회쓸개즙을 치료 후 경과 관찰 중으로, 담낭관이 소통된 경우 수술적 치료 없이 경과 관찰하는 것도 하나의 치료방법이 될 수 있겠다. Limy bile is a rare condition characterized by excessive precipitation of calcium carbonate in the gallbladder; limy bile in the common bile duct is also very rare. Limy bile was first described by Churchman in 1911. The etiology of limy bile is unclear, b
