Antioxidant effects of aqueous Siho extract on lipid peroxidation were determined by TBA value and also by lipid peroxidation value during the autoxidation of Iinoleic acid. Siho extracts exhibited markedly antioxidant aCtivity, which inhibited 99% of linoleic acid peroxidation. And Siho extracts showed 42% scavenging effect on α,α-dlphenyl-β-pjcrylhydrazyl radical, also exhibited a 60-94% inhibitory effect on superoxide generation. Siho extracts dose-dependently protected the cell death induced by tert-butyl hydroperoxide (t-BHP) and significantly increased cell viability In the normal rat liver cell(Ac2F) . These results suggested that Siho might play a protective role in lipid peroxidation by free radicals. Key Words: lipid peroxidation ; Siho extracts; scavenging effect

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

최순영,김창숙,이명혜,황문옥,민경희 숙명여자대학교 자연과학연구소 1991 자연과학논문집 Vol.- No.2

원유 분해세균에 의한 원유 분해능을 조사한 결과, Xanthomonas campestris M12. Xanthomonas sp. M28, Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, 그리고 Pseudomonas maltophilia N246 등의 순서로 나타났다. Xanthomonas campestris M12, Xanthomonas sp. M28, 그리고 Pseudomonas maltophilia N246 균주 모두 octane 분해시의 온도는 30℃에서 최적이었으며, 최적 pH는 X. campestris M12와 Xanthomonas sp. M28이 7.0∼7.5이었고, P. maltophilia N246이 7.5∼9.0이었다. N246 균주의 최적 NaCl 농도는 3.0∼3.5%이었다. P. maltophilia N246와 X. campestris M12는 모두 플라스미드를 갖고 있음을 확인하였고, N246 균주로부터 플라스미드를 제거하였을 경우 octane 분해능이 소실되었으므로 이 플라스미드 위에 octane 분해 유전자가 있음이 확인되었다. 이 균주의 OCT 플라스미드의 크기는 118kb이었다. 또한, N246 균주는 ampicillin 항생제에 내성을 나타내었다. Xanthomonas campestris M12. Xanthomonas sp. M28. Acinetobacter lwoffi G1, and Klebsiella pneumoniae L25, Pseudomonas maltophilia N246 were screened to increase the ability for crude oil utilization. All of these could utilize hexadecane and octane with the exception of N 246 strain for only octane biodegradation. Thus N246, M12, and M28, strains were specially examined for octane oxidation. Octane biodegradation by three strains showed the optimal conditions at 30C, pH7.0∼9.0 and 0.2∼0.3% octane concentration as a substrate. It was found that P. maltophila N246 and X. campestris M12 had plasmid and the cured plasmid from N246 strain lost octane utilization. Therefore, it was confirmed that certain genes for octane utilization were located on OCT plasmid in N246 strain. The size of OCT plasmid in N246 strain was 118 kb. The N246 strain was resistant to ampicillin.

Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.

When the motion of vibrating structure is restrained by the adjacent objects, its vibration frequencies and mode shapes are changed. In general, the vibration characteristics of the system becomes unpredictable. Although the importance of the study on this type of vibration model increases in many engineering areas, most studies conducted to date were focused to the theoretical study on dynamic responses of the structure with stops, including a few experimental works. Specially, the study on the nonlinear phenomena due to the impact between a structure and stops have been mainly performed theoretically. It is, therefore, desired to find a way to have a better understanding on the vibration characteristics caused by the impact of a structure to stops. In the paper, both numerical analyses and experiments are conducted for a fixed-free beam that is restrained by the stops at the free end. The chaotic vibration characteristics of the nonlinear motion and the dynamic response of the system are investigated and presented for various magnetic forces between stops.

서비스 産業의 效率性 測定에 관한 硏究

崔文卿 漢陽大學校 産業經營硏究所 1989 産業經營硏究 Vol.1 No.-

Because of the increasing importance of services in the economy, techniques are being developed specially to measure different aspects of service performance. Service organizations have the following characteristics: customer participation, simultaneous production / consumption, lost production capacity over time, customer dictated site locateion, labour intensive, and intangible product. The intangible nature of the product produced by service organization causes difficulties when managers attempt to measure service performance. For example, measuring performance in terms of efficiency, effectiveness and productivity can be difficult when the productis intangible. Charnes. Cooper and Rhodes opened up a new nonparametric approach, referred to as data envelopment analysis (DEA), to empircally meassure the relative efficiency of decision making units (DMU). Following the efficiency concepts proposed by Farrell, the new method generalizes the productive efficiency measurement regarding multiple inputs and output in the form of a fractional nonlinear programming model. Unlike most of the econometric / statistical approaches, this new technique does not require model specifications for underlying production functions with multiple inputs and outputs. Further, identifying a peer group of DMU, as a reference, the method may provide quantitative information regarding aspects and sizes of adjustments needed to change an inefficient DMU efficient. DEA is more appropriate for measuring efficiency in service organizations than are the more commonly used measures.
