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.

Purpose : To report the incidence of radiological findings from screening panoramic radiographs and verify the validity of the panoramic radiography for screening purposes. Materials and Methods : Six thousand one hundred and sixty panoramic radiographs taken from the patients visiting the Health Promotion Center of CNUH were selected for this retrospective study. Panoramic radiographs were examined into the following pathologic conditions : the presence of periodontal bone loss, dental caries, periapical radiolucencies, retained roots, impacted supernumerary teeth, impacted third molars, odontoma, cystic lesions other than radicular cyst, sialoliths, and mixed radiolucent-radiopaque lesions Number of pathologic conditions and Prevalence values were recorded. Results : The prevalences of pathologic conditions were 72.9% of periodontal bone loss, 32.2% of dental caries, 11.9% of periapical radiolucencies, 10.8% of retained roots, 0.4% of root fracture, 1.0% of impacted supernumerary teeth, 1.0% of impacted third molars, 0.06% of odontoma, 0.08% of cystic lesion other than radicular cyst, 0.2% of prolonged retention of deciduous tooth, 0.1% of sialolith, and 0.04% of mixed radiopaque and radiolucent lesion. Conclusion : Although the panoramic radiograph should not be used to replace intraoral radiographic and clinical examinations, this study showed that many dental pathologic conditions could be detected on panoramic radiographs. The panoramic radiograph might serve as a diagnostic aid in dental health evaluation programs.

The purpose of this study is to identify the construction background of the permanent racecourse constructed by the Japanese around Seo-myeon Busan in 1930 and to analyze the historical meanings of city, architectural characteristics of racecourse facilities at the time of completion and the transition process by addition and improvement after the completion. The Busan Horse Racing Contest held at the land reclaimed from the sea of Busanjin in 1921 at the first time was settled at Seo-myeon opening permanent racecourse in 1930. The change of racecourse location into Seo-myeon instead of Yeonsan-ri as the original location reflects the historical meanings of city such as the accessibility of public transportation, the availability of securing a location for racecourse facilities, the extension of a city and the preparation of military base. The Seo-myeon racecourse completed on November 18, 1930 cost 15,550 won. Its stable was built in 1931, extensively repaired in 1932 and rebuilt in 1940. The betting shop which has been known as the building constructed during the Japanese Colonial Rule is considered to be the building constructed after August 1948.

Generally, a street-inlet in road facility is aimed to exclude rainfall and filth from sewer system. In order to solve some problems in current street inlet facilities, some revised inlet systems have been suggested. Those revised facilities can also solve an environmental problem like a bad smell emitting from the worn facility and solve civil petitions due to its safety and poor quality of passing rainfall. In this study, the existing rainfall exclusion facility was investigated including foreign countries and a developed street inlet model was represented through estimating of their structures, characteristics and costs. It also be analyzed that the existing problems can be solved by a trial construction and the developed model was compared with existing models by focusing on constructability and maintenance capacity.

We investigated the relations between serum cTnI concentration and the prognosis in four dogs which admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with clinical signs such as couching, respiratory distress, anorexia, and/or syncope and were diagnosed as a mitral valve insufficiency. While serum cTnI concentration was less than 2.0 ng/ml in case 1,2 and 3, it was 2.5 ng/ml in case 4 which showed the most grave prognosis. Thus, it is assumed that increased concentration of serum cTnI in dogs with mitral valve insufficiency could be an indicator to evaluate patients' prognosis.

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.
