The building is getting bigger and higher in urban areas to promote efficiency of land. As a building was built in urban areas. it was built in very close proximity. At stage of underground work, it's extremely necessary to improve retaining wall for raising the quality of construction. The Braced Wall System largely used in Korea because of suitability of construction in close proximity but it can't serve enough space to work. So in this study, a new retaining wall method using Prestress Wales compares with Braced Wall System under several aspects such as time for completion, construction cost, and stability.

Centrifuge model tests were performed to find appropriate equations proposed previously of estimating the bearing capacity of the composite clayey soil reinforced with sand compaction pile. Model tests were carried out with changing the replacement ratio of SCP (20%, 40%, 70%), contents of fine materials (5%, 10%, 15%) and ratio of treated width to loading width (1B, 2B, 3B). Test results about bearing capacity of the composite ground were obtained by performing the surcharge load tests with measurements of applied loads and vertical displacement. Bearing capacities against bulging and shear failures were estimated by the existing equations. As results of comparing the estimated bearing capacity with experimental values the bearing capacities estimated by Greenwood's equation (1970) for bulging failure mode were similar to the test results.

유경재,강창수 啓明大學校 醫科大學 1986 계명의대학술지 Vol.5 No.2

Dupuytren's contracture is characterized by progressive fibroplasia and contracture of palmar fasica with resultant deformity of hands and fingers. Reccently it has been shown that the cellular element, called myofibroblast, contributes significantly to the process of contracture. Among the 6 patients we have seen during the last few years, there were a total of 9 hands with Dupuytern's contracture. Seven of these were treated by a partial fasciectomy or by a dermofasciectomy with a full thickness skin graft and the results of these two procedure were compared. The results of ermofasciectomy with full thickness skin graft are better than those of partial fasciectomy, and no local recurrences in the operative site after dermofasciectomy with full thickness skin graft. Electron microscopic studies were done to find myofibroblasts which have characteristics of both fibroblasts and smooth muscle cells in 3 of 6 patients and myofibroblasts were found in 2 of them.

Deep level in horizontal Bridgman(HB) undoped GaAs were investigated by DLTS system personally manufactured. In as grown sample, T1(E_(C)-0.32eV), T2(E_(C)0.54eV) and T3(E_(C)0.82eV) were observed. These levels correspond to EL6, EL3 and EL2 respectively. As sample was annealed at 650℃, T3 level was separated into T3*(E_(C)0.74eV) and T3 level. When sample was annealed at 800℃, only T3* level was observed. For sample annealed at 900℃, T3* and T3 level were observed. From these results, we conclude that the EL2's behavior of annealing temperature can be explained by the model of As_(Ga)-V_(Ga)-A_(Sl)-V_(As).

This study was performed to measure the skin absorbed doses from full mouth standard intraoral radiography(14 exposures) in bisecting angle and paralleling techniques. Thermoluminescent dosimeters were used in a phantom. Circular tube collimator(60mm in diameter, 20cm in length) and rectangular collimator(35mmX44mm, 40cm in length) were set for bisecting angle and paralleling techniques respectively. All measurement sites were classified into 8 groups according to distance from each point of central rays. The results were as follows: 1. The skin absorbed doses from the paralleling technique were significantly decreased than those from the bisecting technique in both points at central ray and points away from central ray. The percentage rates of decrease were greater at points away from central ray than those at central ray. 2. The skin absorbed doses at the lens of eye, parotid gland, submandibular gland and thyroid region were significantly decreased in paralleling techniuqe, but those of the midline of palate remained similar in both techniques. 3. The highest doses were measured at the site 20mm above the point of central ray for the mandibular premolars in bisecting angle technique and at the point of central ray for the mandibular premolars in paralleling techniques. The lowest doses were measured at the thyroid region in both techniques.

진행성 치매와 반복되는 뇌졸중을 보인 뇌 아밀로이드 혈관병증 1예

유봉구,곽강호,김태유,김광수,유경무 대한치매학회 2004 Dementia and Neurocognitive Disorders Vol.3 No.1

Cerebral amyloid angiopathy can cause intracerebral hemorrhage, progressive dementia, seizure and transient ischemic attacks. Dementia is a relatively common manifestation and associated with the presence of recurrent strokes and leukoencephalopathy. A 66-year-old right-handed man with hypertension and recurrent strokes presented with rapidly progressive dementia and sudden onset of dysarthria and dizziness. He showed memory impairment, personality and behavioral changes, and executive dysfunction for one and an half years. These symptoms developed insidiously and quite rapidly without fluctuation. Brain CT showed a small hemorrhage in the right cerebellum. Brain MRI, especially gradient-echo images revealed multiple cortical and cortico-subcortical microbleeds. Four weeks later, right hemiparesis suddenly developed and a repeated MRI showed a new left corona radiata infarction. We learn from this case that gradient-echo MR images should be performed in patients with rapidly progressive dementia and recurrent strokes.

At present, the treatments of the radiation-induced diseases are only performing by the palliative treatment technique. Moreover, radiation protective agents are a little toxic for human being and this seriously limits their applicability with various complications in clinical uses. Accordingly, as a part of the aim of gain of the basic data for protective roles of some radioprotectors, the present investingation was carried out to evaluate the comparative radioprotective effects by the administration of DDC, MEA, WR-2721. Results are shown for statistically significant analysis and correlation with each group as follows; 1. The proper doses of the radioprotectors were DDC; 1,550mg/kg, MEA; 450mg/kg, WR-2721; 780mg/kg of the mouse body weight. 2. DMF(Dose modification factor) of LD50/10 and LD50/30 for whole body irradiation was DDC; 1.2, MEA; 1.4, WR-2721; 1.9 and DDC; 1.7, MEA; 1.8 and WR-2721; 2.5 respectively. 3. DMF for radiation reaction of jejunal crypt was DDC; 1.07, MEA; 1.21 and WR-2721; 1.76 and that of jejunal crypt cell was DDC; 1.04, MEA; 1.08 and WR-2721; 1.38 respectively. 4. Conclusively, WR-2721 was the most effective drung among the three radioprotectors and this result must be a supportive data for further study for clinical application.
