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.

Obesity which is defined as accumulation of excess body fat, is central factor of insulin resistance syndrome. Recently, it is revealed tat adipose tissue is not simply an energy storage organ but it also secretes a variety of molecules which affect the metabolism of the whole body, those are leptin and plasminogen activator inhibitor-1(PAI-1). Therefore, leptin and PAI-1 are increased in the obese state. Leptin regulates energy homeostasis and satiety and PAI-1 regulates fibrinolytic system. For these reasons, elevated levels of leptin and PAI-1 are considered as link factors between obesity and insulin resistance syndrome. However, the exact regulating mechanism for serum levels of leptin and PAI-1 is not fully understood yet. In this study, to evaluate the regulating mechanisms of serum levels of leptin and PAI-1 according to the weight changes, we measured leptin, PAI-1, physical, metabolic, and endocrine parameters during 10 days of weight reduction and 10 days of regain period in 7 young athletes. The mean body weight change was -4.7 kg(5.0%) in the weight reduction period and -2.4 kg(2.5%) in the weight regain period compared to baseline value. Baseline level of leptin in athletes was 1.7±0.66 ng/ml, which was significantly correlated with body weight, BMI, percent body fat, body fat mass, triglyceride, insulin, and PAI-1. Baseline level of PAI-1 in athletes was 16.6±5.26 ng/ml, which was significantly correlated with body weight, BMI, triglyceride, insulin, and leptin. Leptin was decreased to 0.7±0.39(44% of the basaline value) in the weight reduction period, and increased to 1.9±0.64(119% of the baseline value) in the regain period. PAI-1 was decreased to 7.4±2.72(44% of the basaline value) in the weight reduction period, and increased to 22.8±7.33(138% of the baseline value) in the regain period. The changes of leptin during weight reduction period were significantly correlated with the changes of insulin(r=0.890, P<0.01) and triglycerides(r=0.874, P<0.01). The changes of PAI-1 during weight reduction period were significantly correlated with the changes of FFA(r=0.889, P<0.01) and triglycerides(r=0.869, P<0.05). The changes of both leptin and AAI-1 during weight regain period were significantly correlated with the changes of insulin(r=0.755 and 0.849, P<0.05, respectively). In summary, these results suggest that serum levels of leptin and PAI-1 were affected by weight cycling, the percentages of change were more greater than that of weight change, and rebound phenomena were occurred during weight regain period.

R-proximity space에 관하여

鄭雲慶 建國大學校 敎育硏究所 1976 論文集 Vol.1 No.-

The proximity structure was essentially discovered in the early 1950's by Efremovic (1) when he axiomatized the proximity relation 'A is near B' for subsets A and B of any set X. The set X together with this relation was called an infinitesimal space, and a natural generalization of a metric space. In this note we introduce the idea of R-proximity nearness which is a generalization of the concept of metric. R-proximity is the generalization of the Efremovic proximity. we prove that the topology Τ(δ) induced by R-proximity is equivalent to the regular topology. And also we present the alternative description of the R-proximity by the concept of δ-neighborhood. In the last section we study the R-proximity mapping which is equivalent to the continous function in regular space.

은유적 자서전으로 본 케이트 쇼팬의 『각성』

박경운 한국현대영미소설학회 2002 현대영미소설 Vol.9 No.2

The various interpretations of Kate Chopin's The Awakening (1899) have mainly concentrated on the ending of the novel -- Edna Pontellier's suicide and related issues -- because the ending engendered in traditional readers cultural shock and confusions over feminist questions as it deals with issues like women's freedom, independence, and sexual emancipation in the very late 19th century. After the publicaion of the work, The Awakening remained mired in a critical underground for more than 60 years until a Norwegian scholar called Per Seyersted reedited and republished it in 1969. This paper examines Edna Pontellier's search for her true self as it mirrors Kate Chopin's own search for her artistic beliefs and what she tries to convey in the text. The paper will interpret the ending of the novel in terms of an autobiographical perspective reflecting the author's life as a woman artist on Edna's life and death. Although Edna's whole life might not be the direct and consistent reflection of Chopin's specific biographical facts, Edna can be read as an artistic and cultural alter ego of Chopin: the woman writer who poses some serious questions on women's independence, defies restrictive and dualistic conventions, and asserts her own subjective and individual demands against the socially and culturally unfavorable environment. Therefor, Edna's final resolution -- her climactic suicide -- can be taken as a metaphorical parallel for Chopin's courageous publication of the work -- an artistic suicide amidst a public that for 60 years would neglect the novel.
