본 연구는 낙동강 하구 일대의 생태계 변화와 생태 관련자료를 GIS DB로 구축하고 생태지도를 작성하였다. 생태지도 작성을 위해 1984년 11월 21일, 1997년 5월 17일에 촬영된 공간해상도 30m의 Landsat TM 위성영상과 국립지리원에서 발행된 1:25,000 수치지형도, 부산시에서 조사한 생물현황 자료를 바탕으로 DB를 구축하였다. 생태지도를 작성하기 위해, 첫째, 낙동강 하구 생태계 조사 보고서와 현재까지 진행된 생태지도에 대한 문헌 연구, 둘째, 시계열적 토지피복분류도 제작, 셋째, 동·식물상, 수질 등 생태계 항목별 BB 구축과 3단계 방식에 의한 생태계 평가, 최종적으로는 이러한 분석 결과를 바탕으로 생태계 관리를 위한 생태지도를 작성하였다. This study developed an ecological mapping technique with GIS database using the analyses of existing ecological survey reports and the change detection on the Nakdong river estuary. The data which are used to establish GIS DB include 2 Landsat TM images on Nov. 31, 1984 and May 17, 1997, 1:25, 000 topographical maps established by National Geography Institution and various ecological survey reports published by Busan metropolitan city government. The details for producing ecological map are as follows. At first, the current methods of ecomapping efforts and previous ecological surveys of Nakdong river estuary were carefully examined. Secondly, the land cover maps were created from the classified Landsat images of 1984 and 1997 for the spatiotemporal ecosystem analysis. Thirdly, the ecosystem was evaluated by using GIS ecological database based on the criteria of botany, zoology and water quality etc. Each criteria was reclassified into 3 stages which describe the overall quality of ecological condition. At last, the comprehensive ecological map was suggested as a prototype of ecosystem assesment and management tool with the discussion of further study. The findings of this study would be a milestone for preserving and managing the ecosystem.

This paper describes an approach for estimating the unsteady flowrate through a hydraulic pipe lines and a components in real time. Concerning the dynamic characteristics of a hydraulic pipe lines, experimental research from the view point of focusing on the unsteady flowrate through a pipe is insufficient because of the lack of adequate flowmeters. In this experiment, a new instantaneous flowrate measurement system making use of a sharp-edged cylindrical choke and LDV has been proposed and developed by the authors. The unsteady flowrate is obtained from the measurements center-line velocity of a circular pipe using LDV and the pressure difference using a sharp-edged cylindrical choke, and experiments on the frequency characteristics are carried out. The results show a good agreement between the estimated and directly measured flowrate waveforms illustrates the validity of the method proposed here.

This research addresses the determinants of salespeople's ethical awareness(SEA) in stock market. The suggested model include several factors such as environmental uncertainty(volatility and diversity), customer orientation, ethical climate and perception of the ethical awareness of supervisor. Some hypotheses that show the relationship between SEA and the factors are suggested. To attain these objective of this research, samples from salespeople were collected. For the analysis of data, reliability test, validity test, correlation analysis, multiple regression analysis and frequency analysis were used with SPSS WIN package. the results show that environmental volatility, customer orientation(3 factor, 1 factor), organization's ethical climate, affect SEA, however, environmental diversity and customer orientation(2 factor, 4 factor) don't work. And, as hypothesized, SEA generally had positive impacts on customer relationship quality(customer's trust and satisfaction).

Portal hypertension is not common manifestation of Caroli`s disease itself but a major problem when it combined with congenital hepatic fibrosis. Liver biopsy was performed and showed irregular fibrosis containing small bile ducts. He was counseled for the future liver transplantation. We present a rare case of Caroli syndrome confirmed by CT and liver biopsy in adult. Caroli syndrome is a rare congenital disorder of intrahepatic bile ducts that is characterized by intrahepatic bile duct dilatation and prominent fibrosis in the portal area. In Korea, only 2 cases have been reported in adult age. A 23 year old male visited emergency room for hematemesis. He had received splenectomy for unclear causes several years ago. He didn`t drink alcohol and serologic tests for viral hepatitis were all negative. Liver imaging study revealed multiple intrahepatic large bile duct dilatation with central

Purpose: Breast conserving surgery using mesh can effectively fill the defective space, but there is the risk of infection. Methods: From June 2007 to August 2010, 243 patients who underwent breast conserving surgery with polyglactin 910 mesh insert for breast cancer at our institution were retrospectively studied. Results: Infection occurred in 25 (10.3%) of 243 patients. When comparing the infection and non-infection groups in multivariate analysis, there was no significant difference in age, underlying disease, preoperative biopsy methods, mass location, axillary lymph node dissection, operative methods, neoadjuvant or adjuvant chemotherapy use, mass size and removed breast volume. The infection appeared more common only in patients with body mass index (BMI) greater than 25. Infection symptoms occurred, on average, 119.5 days after surgery, and the average duration of the required treatment was 34.4 days. Out of 25 patients with postoperative infection complications, 16 (64%) patients underwent incision and drainage with mesh removal, whereas the remaining 9 (36%) only required conservative treatment. Conclusion: During breast conserving surgery, the risk of infection is increased in patients with high BMI, and should be taken into account when considering insertion of a polyglactin 910 mesh. Patient’s age, underlying disease and perioperative treatment methods were not significant risk factors for developing mesh infection. Given that most infections seem to develop symptoms one month after surgery, a long enough observation period should be initiated. Early detection and appropriate conservative treatments may effectively address infections, thus reducing the need for more invasive therapies.
