This paper aims to search the characteristics of urban regeneration in England and find the suggestion for the urban regeneration in Korea. For this purpose, we reviewed the urban regeneration techniques in physical/spatial aspect and established analysis framework for case study, which is consisted of historic/cultural environment, pedestrian street, mixed-use, urban housing, retail facilities. Site for case study was chosen Sheffield City Center district, because she has various experiences concerning urban decline and urban regeneration in modern history. As a result of this study, we can draw some characteristics of city center regeneration in Sheffield such as consistent urban policy & organic linkage between related plans, clear strategic vision & masterplan-led approach, well-developed project oriented urban regeneration plan, collaborative partnership between public/private sector, reflecting resource in place to deliver based on baseline study, and citizen participation and community-based approach etc.

To elucidate the incidences and the clinical characteristics of glomerular diseases in our hospital, we reviewed the clinical records and histological findings of the 117 cases, which were diagnosed as one of the glomerular disease in renal biospy for about 6 years since 1991. In these 117 cases, 74 cases (63.2 %) fell into primary glomerulonephritis(GN), 18 cases (15.4%) into secondary GN, 2 cases (1.7 %) into end stage kidney, 4 cases (3.4%) into tubulointerstitial disease and the biopsy samples were inadequate for diagnosis in 19 cases. In primary glomerular diseases, most common pathologic diagnosis was IgA nephropathy (36.5 %}, followed by minimal change nephrotic syndrome (29.7%). The incidence of IgA nephropathy would be increased if we had biopsied every asymptomatic urinary abnormality (AUA) patients. Systemic lupus erythematosus (SLE) . hepatitis B accounted for most of secondary GN in our cases. One case of progressive scleroderma was included in this secondary GN. Minimal change nephrotic syndrome (22 cases) was the most common cause of nephrotic syndrome, followed by membranous GN (9 cases) and IgA nephropathy (8 cases). 2 cases of primary amyloidosis were presented with nephrotic syndrome. Nephrotic syndrome as presenting symptom in our IgA nephropathy patients was higher than in other studies, which may be due to indication bias for renal biopsy. We suggest that renal biopsy should be done in adult nephrotic syndrome and in SLE, because various kind of glomerular diseases can develop nephrotic syndrome in adult, renal biopsy can affect the treatment and prognosis in each patients and renal biopsy also determines the extent of renal involvement in SLE on which the treatment depends. In AUA urinary patients, renal biopsy could be reserved for the patients who show declining of GFR or rising of proteinuria. Because IgA nephropathy account for most of AUA. and there is no specific treatment for IgA nephropathy, and renal biopsy in those cases is helpful in ruling out the patients who need no treatment.

The extractability and stability of ginkgoflavonolglycosides under presence of several cellulase preparations were investigated. The enzymes used were macerosin, cellulase C and cellulase NC. The content variation of the glycosides was measured with HPLC method, using caffeic acid as an internal standard. The methanol extract of ginkgo leaf, containing the total flavonolglyco-sides of 4.46%, was used for the content comparison. By extraction with the enzymes, each or mixed, the peak levels of all the glycosides began to decrease after 1 or 2 hours. After 24 hour extraction, most of the glycosides were degraded to minor components. The flavonolglycosides in ginkgo leaf were also hydrolysed simply by the water extraction. After 24 hour extraction with water at 40°C, the peak levels of major glycosides were distinctly decreased. Rutin was hydrolysed by enzyme treatment or by ginkgo leaf itself. As a result, it was concluded that the commercially available cellulases and the ginkgo leaf itself contain the activities of β-glycosidase and α-rhamnosi-dase. Kaempferol-3-0-(6' -0-p-coumaroylglucosyl)-rhamnoside and four other ginkgo flavonolglycosides were not hydrolysed under the same condition."

Global Register Allocation plays a major role in determining efficacy of Optimizing Compilers. Instructions involving only register operands are shorter and faster than those involving memory operands. Therefore, efficient utilization of limited number of hardware registers is important in generation good code. Register allocator attempts to map registers in such a way as to minimize the number of memory references. In this paper, we compare several register allocation methods and have designed and implemented a global register allocator using priority-based graph coloring.

우연히 발견된 복부 종괴로 병원에 내원 한 15세 여아에서 방사선학적 검사에서 우측 신장부위에 콩팥세포암종(renal cell carcinoma)이 의심되었으나 수술 후 Willms 종양으로 진단되어 NWTS-Ⅳ 지침에 따라 합병증 및 재발없이 치료중인 사춘기 Wilms종양 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Wilms' tumor or Nephroblastoma is the second most common mailgnant abdominal tumor in childhood. It usually occurs in children between 2-5 yr of age and is very rare in adolescent and adults. In here, we report the case of a 15-year-old female with Wilms' tumor. On imaging studies, we confirmed the presence of a 22×18×13cm mass in the right kidney. A radical transabdominal nephrectomy was performed and the mass showed histologically Wilms' tumor. She received combination chemotherapy according to NWTS(national Wilms' tumor study)-Ⅳ guidelines and have been alive and well for the last 8 months without severe complication or relapse.
