Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

설악산 국립공원지역 산간계류의 17개 지점에서 2000년 6월부터 2001년 6월까지 어류상 및 이화학적 요인을 계절별로 총 4회에 걸쳐 분석하였다. 모든 조사지점은 1~3차의 하천으로 비교적 물리·화학적 교란이 적었으며 하천폭은 5~30 m 정도였다. 채집된 어류는 총 18과 42종 2,557개체였고, Cyprinidae는 16종으로 84.7%의 상대풍부도를 나타냈으며, Gobiidae 4종, 5.0?의 상대풍부도를 보였다. Cyprinidae는 전체 채입종의 37.2%를 나타냈다. 우점종은 Zacco temminck로 10개 지점에서 738개체가 채집되어 28.9%의 상대풍부도를 나타냈으며, 아우점종은 Rhynchocypris kumkangensis와 Z. platypus로 각각 4개 지점 648개체(25.3%)와 7개 지점 344개체(13.5%)로 나타났다. 한국고유종(Korean endemic species)은 모두 4과 11종 781개체로 30.5%의 상대풍부도를 나타냈으며, 고유화 빈도는 25.6%로 한국의 평균 고유화 빈도와 유사하게 나타났다. 본 조사에서 외래어는 채집되지 않았다. 국립공원 내에 서식하는 어류의 다양성 유지와 회복을 위해서는 공원 내는 물론 경계지역 하천의 체계적인 관리가 요구된다. The fish fauna of mountain streams in the Seorak National Park area was investigated from June 2000 to June 2001 (4 times). All 17 sites were relatively undisturbed 1st to 3rd order streams. A total of 2,557 individuals were collected and classified into 17 families and 43 species. Cyprinidae accounted for 37.2% (16 species) of the total fish species and 84.7% (2,165 ind.) of the total abundance. Subdominant families were Gobiidae (4 species, 5.0%) and Balitoridae (3 species, 3.4%). Zacco temmincki (RA 28.9%, 10 sites) dominated. Subdominant species were Rhynchocypris kumkangensis (25.3%, 4 sites) and Zacco platypus (13.5%, 7 sites). Eleven of the species are endemic to Korea (4 families, 30.5%). Exotic species were not collected in this survey. Fish diversity was higher in streams around the boundary area than in the national park. Therefore, management of streams in the boundary area to protect the fish biodiversity can be efficiently conducted. Habitat degradation should be reduced for the conservation and restoration of fish diversity.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Colon cancer is the second most common malignancy in Korea. It is classified as superficial type, the mass type, the ulcerative type, the ulceroinfiltrative type, the diffuse infiltrative type and the unclassified type according to the colonoscopic findings. We report here on a case of colon cancer that was initially misdiagnosed as acute infectious colitis at the initial presentation. A 64-year-old man visited to Yeungnam University Hospital for watery diarrhea and lower abdominal pain. Colonoscopy revealed long segmental edematous mucosa and hyperemic mucosa with stenosis in the transverse colon. He was diagnosed as having acute infectious colitis according to the colonoscopic finding. However, two days later after colonoscopy, he visited the emergency room for hematochezia. We performed computerized tomography (CT) and obtained blood samples to find the origin of the bleeding. We found thickening of the transverse colon lumen and ascites on the CT finding and an elevated level of tumor markers; we also obtained the results of the colonoscopic biopsy that was done via colonoscopy. He was finally diagnosed as having colon cancer with carcinomatosis, a poorly differentiated adenocarcinoma.

Unsteady flow in a natural river which meanders through a wide flood plain is complicated by large differences in hydraulic resistance and cross sectional geometry of the river channel and the floodplain. The unsteady flow is further complicated by the tendency for a portion of the flow to short-circuit along the more direct route afforded by the flood plain rather than following the longer route along the meandering channel. A mathmetical model for routing floods in meandering river with floodplains is presented. The one-dimensional equations modified such that the flow in the meandering channel and floodplain are identified separately. The floodplain model has been used to simulate flow in an idealized meandering river with a flood plain. Flood peak attenuation and travel time are found to increase as flood-plain roughness and width increase and as channel sinuosity decrease. Attenuation increase and travel time decreases as the flood plain flow increases.

자동차 주유시 대기중으로 빠져 나온 연료 증기는 환경을 오염시킨다. 주유시 연료증기 방출량을 최소화하기 위해서 ORVR 시스템이 적용된다. 그러나 이 시스템은 몇가지 어려운 기술적인 문제들이 존재한다. 본 연구에서는 주유 유량에 따른 연료 증기 방출량을 예측하였다. 이를 위하여 연료 탱크의 압력 변화, 연료 증기가 흡착되는 캐니스터로의 방출량을 시뮬레이션하였다. 연료 증기와 공기의 혼합 기체는 이상기체로 가정될 수 있다. 주유관을 흐르면서 액체 연료의 압력 강하는 유량과 주유관의 형상에 따라 각각 계산하였다. 압력 강하 검증을 위해서 직선관과 90도 곡관에 대해서 수행하였다. 또한 shut-off time을 예측하여 실험치와 비교를 하였다. 계산 결과 40 LPM 이하에서는 연료탱크가 가득 찰 때까지 주유가 되고, 이상에서는 매우 빠른 시간에 shut-off가 됨을 알 수 있었다. 더 나은 모델을 개발하기 위해서는 연료의 증발, 응축 그리고 연료 탱크내의 기체의 유동까지도 고려되어야 할 것이다. During the refueling process of automobiles, the fuel vapor escapes into the atmosphere and pollutes the environment. To reduce the fuel vapor emission during refueling, ORVR(Onboard Refueling Vapor Recovery) system is implemented. This system, however, needs to overcome several technical difficulties. This research studies the problem of the fuel vapor emission and the refueling flow rate in ORVR system. The pressure variation of the fuel tank during the refueling and the emission to the canister that absorbs the escaping fuel vapor are numerically simulated. The fuel-vapor and air mixture in gas phase is assumed to be ideal gas mixture. The pressure drop of liquid fuel through the refueling line is numerically calculated for various flow rates and shapes of the pipes. The results are verified for straight and 90 degree bend. The shut-off time is calculated and compared with experimental results. The flow rate of forty liter per minute is determined to be the critical refueling rate. Below 40 LPM the refueling process continues until the tank is filled, but above it the shut-off occurs at the early stages of refueling process. Experimental results and simulation results show good agreement. To improve the model, the transient evaporation and condensation are to be considered as well as the gaseous flow inside the tank.

Objectives : This study is designed to discuss the pros and cons related to the 'separation of drug prescription and dispensation' system when 5 years have passed by since the introduction of this system. Methods : The 592 psychiatrists from 1,107 working places took part in nationwide survey by mail or E-mail from June to September, 2005. The response rate was 23.8%, most of respondents came from private clinics. Results : The average age of psychiatrist was 44.6 years old, ranging from 25 to 75, most of them was predominantly male. The main results were as followings : 1) The ratio of psychiatric prescription out of hospital based on out-patients departments was the lowest in clinics, following by hospitals, general hospitals and university hospitals by order. 2) The main reasons of customer's preference for out of hospital prescription were economic advantage and self-awareness of prescription. As for the disliking for it, the most complaints were the anxiety about disclosure of psychiatric treatment, in convenience for delay and concern about drug change. Conclusion : Five years didn't seem to give a change on how the psychiatrists perceive the 'separation of drug prescription and dispensation' system at all. The confidentiality and human right issues on the part of psychiatric patients should never be ignored in order to manage this system successfully.

The callback mechanism is one of the most effective cache consistency strategies to maintain high level consistency and preserve scalability for reliable and fast networks. The development of modern network communication techniques has affected on the advent of portable and mobile computers. With these products, clients can communicate with servers through wireless networks regardless of their locations while they are moving around. The drawback of mobile hosts is that they experiences frequent disconnection of communication and weak connection due to low bandwidth and power. These frequent disconnections result in increasing validation checks for data consistency, and therefore, network traffic and service delay is more increasing. In conclusion, the effect of callback mechanism in these systems is considerably reduced. Mobile hosts have low bandwidths, and are required to effectively use bandwidths to reduce the number of data transfers between clients and servers. The increase of network traffics obstructs the scalability and data availability of mobile environments. This paper proposes caching scheme for reduction of network traffic in mobile computing environments.
