DLTS 장치의 제작과 응용

兪長壽,金慶根,金仁洙 대구산업정보대학 1995 논문집 Vol.9 No.2

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).

Dupuytren구축의 임상 및 전자현미경학적 관찰

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.

Dementia with motor neuron disease includes frontotemporal dementia with motor neuron disease, amyotrophic Creuzfeldt-Jakob disease, Parkinson-amyotrophic lateral sclerosis-dementia complex, familial amyotrophic lateral sclerosis, and hereditary spastic paraparesis. A 54-years-old man presented with a eight month history of rapidly progressive dementia. Progressively more severe dementia was accompanied by muscle wasting and visible fasciculations. Cerebrospinal fluid showed the 14-3-3 protein. Brain MRI revealed mild diffuse atrophy in both frontal, temporal and parietal lobes. He died 9 months after onset of the disease. We report a patient with sporadic Creuzfeldt-Jakob disease with motor neuron disease.

In this study, the researcher investigated how tailored garment were accepted and developed in India where the traditional costumes, such as Sari and Dhothi, excluding the tailored process, were mainly worn. It is suspected that pants and coats were first introduced during the Kushan Dynasty but they scarcely influenced on the costumes of India. In the 7th Century when Islam made its entrance in India, pants and coats were not accepted in India due to the exclusive attitudes of Indians, Hindu. Pants and coats were worn locally as Indian costumes through the Islamic Mughul Empire in the 16th Century. During that period, the cultural exchange between Islam and Hindu made the change of the clothes of India reflected the mixing of Islamic and Hindu elements. The colonization of India by Great Britain that was the turning point fur diverse kinds of tailored garment in the costume history of India inasmuch as western elements were introduced. The western style tailored method and design changed the appearance of Indian pants into slimmer style. The style spread and influenced on the design of indian clothes greatly; hence, western style shirts and coats were accepted in India.

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.

The aim of this research is to analyze Vionnet's geometric features, which can be regarded as the key formative beauty among the external characteristics of her works, and to thereby establish the theory that her works emitted a time-transcending life force because they were patterns designed based on a geometrical frame of mind. To prove such argument, atudies to understand the basic geometrical aspects appearing in her works will be made by taking a look at the general features of geometry, viewing Vionnet's philosophy for designing and examining the geometric cutting methods. The period covered in this paper will center mainly on dresses Vionnet made from her very active days in the fashion sector. 1919, till when she retired from the fashopn industry, around 1939. What's outstanding about Vionnet's geometric principle expressed in her works is the unique cutting method that acknowledges the silhouette of the human body as a cubic or three-dimensions concept, through insight of the human body, the mechanics of the materials, and geometry. Vionnet introduced a simple and elegant design by combining geometric figure cuts, such as rectangles, quadrants, and triangles Moreover, she created a new sewing structure that plans everything about the materials to the tiniest detail, resulting in producing a softer style. With this, Vionnet showed the geometrical correlation can bring about harmony and the beauty of ideal proportion forming the source of eternal beauty. As discussed so far the geometrical characteristics appearing in Vionnet;s works are marked such as spirals, zig-zag lines, asymmetries, panels, gradation. golden proportion, and the mobius-band.

The purposes of this study were to investigate the physicochemical characteristics and storage stabilities of various sauces with added Yuza(Citrus Junos). Yuza consisted of three parts: peeled (46.17%), fleshed (43.74%) and seeded (10.09%). Yuza juice revealed 11.33% extraction yield, pH 2.85, 4.18% total acidity, 11° Brix, 1.16% transmittance and 2.63° Brix/acid ratio. Five kinds of sauces with added Yuza juice were Yuza red pepper paste sauce, Yuza soybean sauce for meat, Shahu shabu Yuza sauce, Korean Yuza vegetable sauce and Japanese Yuza soybean sauce. These sauces showed slight changes in pH, total acidity, total bacterial counts and overall sensory characteristics during storage period (60 days). In conclusion, Yuza juice could be applied to various sauces, which remained usable for 60 days.
