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.

Inflammatory myofibroblastic tumor of urinary bladder is a rare benign entity that clinically and radiologically simulates a malignant tumor. This benign lesion must be differentiated histoloeically from several malignant lesion of the bladder. Complete surgical excision, either by transurethral resection or partial cystectomy, appears to be curative. We report a case of inflammatory myofibroblastic tumor of the urinary bladder in a 25-year-old female.

전신성 홍반성 루푸스(systemic lupus erythematosus, 이하 SLE)는 원인을 알 수 없는 자가항체 및 면역복합체로 인하여 여러 장기의 손상을 초래하는 질환이다. SLE의 신경정신의학적 증상에 대하여는 1872년 Kaposi에 의해 처음 기술되었다. 이때에 나타나는 임상적 양상은 상당히 다양하여 정신증, 우울증, 뇌졸증과 인지기능장애등을 포함한다. 이들은 종합적인 정신과적 평가를 위해 종종 협의진료가 의뢰되고 있다. SLE의 정신병적 증상은 환자의 사망률을 높이고 좋지 않은 예후를 시사하는 지표가 될 수 있기 때문에 조기 진단 및 치료가 요구된다. 그러나 SLE의 중추신경계 침범에 대한 명확한 진단기준이 마련되어있지 않고, 증상의 다양성과 변동성은 진단을 더욱 어렵게한다. 저자들이 경험한 심한 정신병적 증상을 보인 SLE 3례의 경우, 이들은 지남력 장애, 환시, 환청, 망상, 불안정한 기분을 보였고 자주 충동적이 되거나 난폭해져 자신 또는 타인에게 위험을 초래할 수 있었다. 현재까지 SLE의 정신병적 증상에 대하여 잘 알려져 있지는 않지만, 문헌고찰을 통해 발병기전, 분류진단, 임사양상, 치료등에 대하여 알아보았다. Systemic lupus erythematosus(SLE) is a disease of unknown etiology in which multiple organs are damaged by pathogenic autoantibodies and immune complexes. Neuropsychiatric manifestations in SLE were first described by Kaposi in 1872. These are so diverse that they include psychosis, depression, stroke, seizure and cognitive dysfunction etc.These patients are frequently consulted for psychiatric evaluation. Neuropsychiatric manifestations in SEL re also among the leading causes of morbidity and mortality and associated with poor long-term outcome. So it is essential to recognize and intervene these symptoms early. But the clear diagnostic criteria for CNS involvement in SLE have not been formulated, and diversity and fluctuation of illness make it difficult to confirm it. The authors reported three cases of SLE with severe neuropsychiatric manifestation. These patients showed symptoms such as disorientation, auditory and visual hallucibation, delusion and mood instability. They became frequently impulsive and violent and had risks to injure themselves or others. Although CNS involvement in SLE is not well known, we reviewed the pathogenesis, classification, diagnosis, clinical manifestation and treatment of them.

Background: We wanted to evaluated the long term results of the tension-free vaginal tape (TVT) Procedure for treating strss urinary incontinence in women. Method: During Octover 1, 1998 to December 31, 2005, we evaluated the 52 women who underwent the TVT procedure for stress urinary incontinence at least 1 year following surgery. Preoperatively, Patients were evaluated with history taking, Physical examinations and urodynamic study, Operation and hospitalization data were evaluated with duration of procedure, hospital days, foley catheter removal days and use of analgesics, Postoperative evaluations included the uroflowmetry, residual urine volume, surgical outcomes, complications and patients' satisfaction with the procedure. Results: The follow-up period was a mean of 16 months. Preoperative I-QoL total score was 58.0. Comparision the result between preoperative and postoperative Q max was significantly shoter in the postoperative result. TVT procedure remained cure in 96.2% (cured: 82.7%, improved: 13.5%) and successful in 96.1%. Also, 49(94.2%) Patients would like to recommended the TVT procedure to others. There was no serious or long-term complications, Conclusions: The TVT procedure appear to be effective and safe for the surgical treatment of female stress urinary incontinence and showed a good long-term cure rate.

This experiment was carried out to determine the effect of improvement of oversown pastures, treated with four nitrogen(N) application levels(0, 100. 200. 300 kg/ha) and three species mixtures (A:orchardg-rass+ ladino clover: B: orchardgrass+ ladino clover+ perennial ryegrass; C: orchardgrass+ ladino clover+ perennial ryegrass+ Italian ryegrass). The establishment of perennial ryegrass, Italian ryegrass, and ladino clover were increased with inc-reased N applications. but the ryegrass mixed with orchardgrass and ladino clover decreased the establi-shment of ladino clover. With the increase of N application levels, orchardgrass, perennial ryegrass and Italian ryegrass in com-parison on botanical composition were getting better, while the native plants established already were de-creased. The botanical composition of newly sown pasture plants was increased as cutting times progres-sed. The dry matter(DM) yield of pasture species increased significantly with N application up to 300 kg/ha. There was no significance among mixture treatments, although the DM yield of basic treatment(0rchardg-rass + ladino clover) was higher than other treatments. However, when compared DM yields on each cut-ting times, newly oversown pastures in A treatment was shown to be significantly higher only on 2nd outting time than other treatrnents(P<0.05). The DM yield of native plants survived in basic species mix-ture was significantly less than those of other mixtures(P<0.05). Results of this study indicate that for improving oversown pastures, at least 300 kg/ha N application should be applied, and basic mixture (orchardgrass+ ladino clover) has more advantage than treatments mixed with ryegrass.

김형철,강길호,채만규,김성용,백무준,이문수,박상흠,이문호,김창호,송옥평,조무식,박희주 순천향의학연구소;Soonchunhyang Medical Research Institute 2000 Journal of Soonchunhyang Medical Science Vol.6 No.1

Purpose : The Mirizzi syndrome is relatively rare and preoperative diagnosis of this disease is difficult. In 1978, Morelli suggested the subclassification of the Mirizzi syndrome into acute or chronic form. We experienced 5 cases of acute form. We analysed clinical features, preoperative radiologic findings and operative findings of 18 cases including acute forms which were diagnosed as Mirizzi syndrome and should suggest the modified classification of Mirizzi syndrome for choice of appropriate treatment. Method : From January 1995 to December 1998, 18 cases, of which 8 cases were diagnosed at Soonchunhyang University Chunan Hospital, and 10 cases were reported in the Korean Journal were retrospectively analysed with regard to clinical features, preoperative radiologic findings and operative findings. According to the clinical features, whole cases were divided into type Ⅰ(acute form) and type Ⅱ(chronic form) and then each type of cases were subclassified according to preoperative radiologic findings and operative findings. Results : Of 18 cases there were 5 cases in type Ⅰ(27.8%), 13 cases in type Ⅱ(72.2%). Type Ⅱb was most common. Type Ⅰa cases were treated only with cholecystectomy. We applied cholecystectomy, T-tube choledochostomy and patch technique in type Ⅰb and thpe Ⅰc cases. Cholectystectomies including removal of gallstones and internal drainage procedures were done in type Ⅱ chronic forms. Conclusion : The acute form(Type Ⅰ) of Mirizzi syndrome was suggested by Morelli might be subclassified into typeⅠa,Ⅰb and Ⅰc following the presence of the necrotic defect in common hepatic duct. Through the modified classification of Mirizzi syndrome based on clinical feature, preoperative radiologic findings and operative findings, we can choice appropriate treatment.
