The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

The current trend of If (Information Technology) in 21st century demands management innovation, that is Business Process Reengineering (BPR) in all the industry including construction project. The solution of its demand is proposed by IT based on Internet. And also, in order to meet this objective, from 1997 domestic construction industry is accelerating to systematize CALS (Continuous Acquisition and Life-cycle Support) which is being planned to apply by government. These efforts give much weight to build computer systems rather than to improve and redesign construction business process that is more important for system application. This research develops a model for applying the BPR to construction industry, especially construction site that is a base to build a system for CALS. And the research suggests performing method, process and modeling technique of BPR to be applicable in business process redesign of construction field. Also, focusing on the research of execution step of business in construction site will be helpful for the site worker to perform BPR in construction site.

Background : Medical equipments take a very important role in diagnosis and treatment of disease in modern medicine and effective maintenance of the equipments is a necessory to provide a good healthcare to the public. After developing a new QC program for effective maintenance of medical equipments and practicing it for a year, we report the results of the new program. Methods : The maintenance data of 9 equipments in 8 categories including a CT Scanner were analyzed with regard to the parts responsible for most frequent failure and cause of the failure. After learning the most frequent failure part and cause of the failure, we developed a new QC program that emphasizes preventive maintenance of the most frequent failure part. We compared the number of failure per year and active rate of each equipment before, and after the adoption of the new QC program. Results : The average number of failure per year per equipment was 20.7 before and it decreased by 43% to 11.9 after adoption of the new QC program. The average active rate of the equipments was 92.6% before and it increased by 3.2% to 95.8% after adoption of the new program. Conclusions : The practice of the new QC program appears very useful as it decreased the failure rate and increased the active rate of the equipments.

Acute fatty liver of pregnancy (AFLP) was first described as a specific clinical entity in 1940 and thought to be universally fatal. Maternal mortality in the past approached 75 percent. However early diagnosis and prompt delivery have dramatically improved the prognosis, and maternal mortality rate is now less than 18 percent. A early diagnosis, a prompt delivery, and a intensive supportive care have improved maternal and perinatal outcome. We report a 30—year—old woman at 37 weeks gestation who have multiple complications including acute pancreatitis in AFLP. She was complicated with acute renal failure, disseminated intravascular coagulation, duodenal ulcer bleeding, spontaneous bacterial peritonitis, pulmonary edema and acute pancreatitis.

This paper is studied on the effects of additive of permeability and magnetic reluctance of Ni-Zn ferrites. Ni-Zn ferrites was composed of 20mo1% NiO, 30mo1% ZnO, 50mo1% Fe₂O₃, and 0.0025n1o1%, 0.005mo1%, 0.01 mol% ??, Bi₂O₃, ?? were used as minor additive Sintering was carried oui at 1100℃. As results from the experiments, the initial permeability was proportional inversely to magnetic reluctance. It was observed that the better magnetic properties of initial permeability anti magnetic reluctance could be achieved by the additive ??.

An automatic, programmable facial expression construction method has been proposed in terms of virtual reality implementation application. Several patterns of expressions were stduied to reconstruct those patterns to generalize with another object image experimentally. The results show that any kind of object actions, especially, facial expression, in a range of a certain background could be reconstructed by the pattern manipulation automatically. Smile expression was experimented in this paper, however, cry, angry or any other expression would be derived by using proposed procedure.

Necrotizing pancreatitis develops in about 10-20% of patients with acute pancreatitis, and pancreatic abscesses develop in 3% of them. The mortality of pancreatic abscess has been reported up to 40% in one study. Recently, there are several reports that show good results with n on-surgical therapy, such as percutaneous drainage and endoscopic drainage, but if the non-surgical drainage fails, surgical therapy are recommended. However, there is no definite therapeutic method which is suggested yet so far after the failure of the surgical drainage. So we report the case in which we experienced successful treatment of pancreatic abscess by endoscopic removal of necrotic tissue through the gastrocystostomy, after the failure of the surgical debridement and internal drainage through gastrocystostomy.
