<P>PURPOSE: To evaluate the efficacy and safety of single-session OK-432 sclerotherapy for the treatment of renal cysts. MATERIALS AND METHODS: From October 2005 to November 2006, 48 patients (61 simple renal cysts) were included in the study. Indications were determined as flank discomfort (n = 37) or patient reassurance due to increasing size (n = 11). The simple renal cysts were aspirated under ultrasonography (US), at which point OK-432 was injected into the cyst. Follow-up was performed with US or computed tomography scan every 3 months until 1 year. Complete regression of the renal cyst or more than 70% reduction in size with no symptoms indicated a successful treatment. RESULTS: Among 61 renal cysts of 48 patients, the overall success rate was 98.4%. Complete regression occurred in 46 cysts (75.4%), and more than 90% reduction in size occurred in 6 cysts (9.8%). A size reduction of 80% to 90% and 70% to 80% occurred in five (8.2%) and three cysts (4.9%), respectively. A size reduction less than 70% occurred in only one cyst (1.6%). The success of cyst regression was correlated with cyst volume. Clinical symptoms resolved in 100% of patients with symptomatic cysts, and there was no enlargement of the aspirated cysts at the 1-year follow-up. After the procedure, there were only some minor complications, such as mild fever, flank pain, and leukocytosis, which subsided with the conservative treatment. CONCLUSIONS: Percutaneous OK-432 sclerotherapy is simple, safe, and effective, and it can be an alternative first-line therapy for simple renal cysts.</P>

축압축력을 받는 원통형 쉘의 비선형 붕괴해석

조현영,김성도,김미옥 부산대학교 1995 生産技術硏究所論文集 Vol.48 No.-

To investigate imperfection-sensitivity for the cylindrical shell structures, a numerical method for evaluating the equilibrium path of a cylindrical shell subjected to axial load and eccentrically axial load is presented. The effects of both material and geometric nonlinearities were also considered in the analysis. The nonlinear formulation was based on the total Lagrangian description and the nonlinear equations were solved by the Newton-Raphson method with load incremental procedures. Degenerate shell elements with layered approach were employed for the analysis. Comparing with experimental results, nonlinear collapse analysis of cylindrical shells subjected to axial compression is carried out. The characteristics of the elasto-plastic deformation can be found in several numerical examples and the local eccentricity of the axial load affects considerably on the level of critical load due to local buckling. 불완전량이 있는 원통형 쉘의 좌굴 거동을 조사하기 위해, 중심 축하중 및 편심 축하중을 받는 원통형 쉘의 평형 경로를 재료 및 기하학적 비선형성이 고려된 수채해석을 통하여 추적하였다. 이때의 비선형 중분 평형방정식은 total Lagrangian 정식에 따라 유도되며, 하중증분법과 Newton-Raphson 법으로 해를 구한다. 본 연구에는 충분할 해석이 가능한 degenerate 쉘 요소를 사용하였다. 비선형 붕괴해석 결과와 실제 실험결과와 비교하였으며, 여러 가지 해석예제를 통하여 탄소성 변형의 특성을 알 수 있었다. 그리고 원통형 쉘의 국부좌굴시 편심하중에 의한 내하력의 감소현상이 두드러짐을 알 수 있었다.

제1대구치는 저작과 혼합치열기 이후의 수직적 교합관계형성에 핵심적인 역할을 하고 악골의 성장발육에 관여한다. 제1대구치의 매복은 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 문제점을 야기할 수 있다. 치료방법으로는 주기적 관찰, 외과적 노출술, 교정적 견인, 외과적 재위치술, 발치 등이 있으며 이중 외과적 노출술이 가장 기본이 되는 술식이다. 외과적 노출술시에는 맹출로의 개방성을 유지하는 것이 중요하며 개방성을 유지시키기 위한 방법으로는 레진관의 접착, 산화 아연 유지놀 시멘트, 치주포대 등을 노출된 부위에 충전시키는 방법 등이 있다. 본 증례에서는 매복된 하악 제1대구치에서 장애물의 제거와 외과적 노출술을 시행한 결과 자발적인 맹출을 관찰할 수 있었다. 또한 surgical pack과 투명상유지장치를 사용하여 간편하고 효과적으로 맹출로의 개방성을 유지할 수 있었다.

박경옥,조현주,이상운 대한건축학회 2004 대한건축학회논문집 Vol.20 No.8

This study has its purpose to establish a model for the use of closed schools as core facility of rural community. The closed schools would be used for various activities that residents want, just like health care, medical care, welfare, side-job training and convenience upgrading activities. Japanese cases in this field give us good implications, so that we visited 5 closed schools in Totsuki-ken and Ibaraki-ken for interviews. The results of interviews with facility managers are as follows. (1) For the decision on the usage of facilities, district administration officers, residents, private companies and NPO(Non-Profit Organization) join the procedure. (2) The usage is focused to enhance elderly welfare, to increase household income, and to enforce community relationship. There are facilities with mixed usage of various functions.Because closed schools have symbolic meanings for the community, sufficient discussion with residents is essential for the decision. And social supports as NPO law and nursing insurance of Japan would be indispensible for the successful implementation.

紅蔘 및 白蔘粉末製品에 對한 放射線(^(63)Co-r 線) 照射 및 照射線量과 長期貯藏이 理化學的 特性과 外觀品質 變異에 미치는 영향을 25℃에서 4個月間 저장하면서 조사하였다. 兩試料 모두에서 照射線量과 長期貯藏에 따른 變異가 거의 없었다. 理化學的 特性에서 水分, pH, 아미노態窒素, buthanol extract, 還元糖등과 사포닌분획별 패턴에도 大窒없었으나 白蔘粉末의 경우 특히 50% ethanol extract의 收率이 약간 增加되는 傾向을 보였다. 外觀品質의 경우 50% ethanol extract의 色濃度에서는 大差없었으나 粉末自體의 色度에서는 試料間에 약간 差異가 있었다. 紅蔘粉末의 경우 L値와 a値는 減少되었고 b値는 增加되어 茶褐色化 되는 傾向이었고 白蔘粉末에서는 L値가 減少되고 a値와 b値는 線量에 따라 增加되나 貯藏其間에서는 減少와 增加를 보여 濃黃色化되는 傾向이 었으나 識別可能程度의 色度變異범위는 아니었다. 全體的으로 品質의 安定性을 維持하고 있음을 보여주었다. The effect of the physiochemical properties of red and white ginseng powder after ^(60)Co-r ray irra diationduring the storage fer 4 months at 25℃ was investigated. The storage periods and the treatment of irradation at various doses on ginseng powders had no significant effects on the proximate composition and color density of ginseng extract with 50% ethanol. No changes in the contents of saponin and its HPLC patterns were found during the storage. However, a little increase was found in the yield of 50% ethanol extract and Hunter's color value of powder. But generally it was found to be stable in the physicochemical properties of red and white ginseng powder by irradiation of the intensity during the storage.

박경옥,조현주,이상운 대한건축학회 2004 대한건축학회논문집 Vol.20 No.1

Closed schools in rural areas are hardly used for the residents. The purpose of this study is to suggest the possibility to use these facilities for elderly welfare spaces or community centers of residents. For this purpose this article studied life pattern and use of facilities of rural residents. Interviews on the use of leisure time, additional jobs other than agriculture and the use of facilities were conducted on 91 residents living in the educational area of 2 preliminary schools which were just closed. The 2 schools-Seongdae branch school of Baekgok preliminary school and Ohsang branch school of Gujeong preliminary school- are located in Jincheon-gun, Chuncheongbuk-do. Rural residents have relatively much spare time more than 6 hours a day, but their leisure activities are very restrictive in diversity. Economic burden, lack of time in their agricultural period and inconvenient traffic ask closed schools near and familiar to the residents to be converted to the compound community center with diverse functions and leisure programs. It would improve the life quality of agricultural residents and lessen their economic burden.
