Park, Woon-Yong,Song, Youn-Kyung,Bae, Kyung-Ho,Kim, Yong-Suk 東亞大學校 建設技術硏究所 2005 硏究論文集 Vol.28 No.2

Currently, digital maps in the metropolitan area are supposed to be revised and renewed every two years, but it is difficulty for the renewal of current information to keep pace with the quickly changing society and so, one of the alternative methods being discussed is a digital map produced using high resolution satellites. The biggest problem in the production of digital maps using high resolution satellite images is the difficulty of production in vector resource format through edge detection of satellite images, a Raster data. In this study, topographical boundaries were detected through edge detection of the satellite image, and after vectorliezing using the screen digitizing method, the results were evaluated and compared to the digital map from the NGII(National Geographic Information Institute) for accuracy.

The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

The purpose of this study is to provide restoration methodology of traditional landscape structure of the royal garden by analyzing "Dongkweoldo", including various drawings of Chosun Dynasty royal gardens, and by referring to the historical literature and documents. The results of the study can be summarized as follows: 1. Based on the location analysis of Dongkwoldo's landscape structure, oddly shaped stones, scientific devices, lighting fixtures and Deumoo are placed mostly in living quarters, and rarely found in political arena. 2. Wells and ponds are placed in the backyard harmoniously. They are usually buried and damaged rather than utilized in other methods. 3. Based on "Dongkwoldo" landscape structure analysis, movable landscape structures underwent various changes after the completion of "Dongkwoldo". 4. We can discover changes of "Dongkwoldo" through Donghun Dohyung around 1908, "Chosun Relics Dobo", containing drawings and photography (around late 1920's). These items were produced after the completion of "Dongkwoldo". We can find that unmovable landscape structures such as ponds and wells can be restored through these drawings. 5. Restoration drawing allows us to express these structures in drawing format although scaling is not possible.

The purpose of this study was to determine the effect of bleaching technique on the shear bond strength of esthetic restorative materials to bovine enamel. The bleaching agent was used 35% H_2O_2(Hi-Lite, Shofu, U.S.A.). Experimental groups were divided into two divisions as group A and B. Experimental A groups for the effect of number of bleaching were as follows ; Group Al : no bleaching Group A2 : bleaching 1 time ( for 5 minutes ) Group A3 : bleaching 3 times ( each for 5 minutes ) Group A4 : bleaching 6 times ( each for 5 minutes ) Group A5 : bleaching 9 times ( each for 5 minutes ) Experimental B groups for the effect of storage period in artificial saliva were as follows ; Group Bl : not stored in artificial saliva after bleaching Group B2 : stored in artificial saliva for 1 day after bleaching Group B3 : stored in artificial saliva for 1 week after bleaching Group B4 : stored in artificial saliva for 2 week after bleaching Group B5 : stored in artificial saliva for 4 week after bleaching Composite resin and glass ionomer cement were bonded to all specimens, and the shear bond strength between enamel and restorative material were measured in Instron Universal Testing Machine(Instron, 4467, U.S.A.). Additionally, the bleached enamel specimens were examed after etching with 37.4% H_3PO_4 for 1 min under SEM(S-2300, Hitachi Co., Japan) to observe the effect of bleaching procedure on enamel surface morphology. The result were as follows ; 1. In SEM findings, bleached bovine enamel was found to be superficially rough. 2. In bleached bovine enamel, the effect of acid etching was reduced with the increase of number of bleaching. 3. The mean shear bond strength of composite resin and glass ionomer cement to bleached enamel surface tended to be lower than those to non-bleached enamel surface. 4. With the increase of number of bleaching, the shear bond strength of composite resin and glass ionomer cement to bleached enamel were progressively decreased. 5. Increasing the storage period in artificial saliva after bleaching, the shear bond strength of composite resin and glass ionomer cement to bleached enamel were progressively increased. 6. The mean shear bond strength of glass ionomer cement to bleached bovine enamel tended to be clearly lower than that of composite resin.

In this paper, the error compensation method of the low-cost IMU is proposed. In general, the position and attitude error calculated by accelerometers and gyros grows with time. Therefore the additional information is required to compensate the drift. The attitude angles can be bound accelerometer mixing algorithm and the heading angle can be aided by single antenna GPS velocity. The Kalman filter is used for error compensation. The result is verified by comparing with the attitude calculated by Attitude Heading Reference System with Micro Electro Mechanical System for a basis

Fourty-six cases of gestational trophoblastic neoplasms (32 cases of hydatidiform mole; 4 cases of invasive mole; 10 cases of choriocarcinoma) and five cases of normal pregnancy as control group were studied for the distribution and intensity of human chorionic gonadotropin(HCG), human placental lactogen(HPL) and regnancy specific beta-1 glycoprotein(SP-1) by immunoperoxidase method. The following results were obtained. 1) The HGC was seen in the syncytiotropholasts, but not cytotrophoblasts of normal placental tissue and hydatidiform mole in all 3 grades. However, in the invasive mole and choriocarcinoma, the HCG was also seen in the cytotrophoblasts. 2) The HPL and SP-1 were only seen in the syncytiotrophoblasts in all those trophoblastic neoplasms. 3) The more malignancy was progressed, the more intensity of the HCG in the syncytiotrophoblasts was increase. Especially, it was severe intensity of positivity in the choriocarcinoma. 4) Intensity of the HPL in the syncytiotrophoblast had the tendency of increase in the invasive mole. But, it was variable in the choriocarcinoma. 5) Intensity of the SP-1 in the syncytiotrophoblast had the tendency of increase in the grade Ⅱ of hydatidiform mole. But thereafter, it was decreased or variable in more aggressive trophoblastic neoplasms, In conclusion, the HCG, HPL and SP-1 were present in the syncytiotrophoblasts of normal placental tissue and various trophoblastic neoplasms. And, the more severe hyperplasia and undifferentiation of trophoblasts were seen, the more intensity of the HCG was increased, suggesting that the HCG can be a useful tumor marker of prognosis in gestational trophpblastic neoplasms.
