Spatial distribution of centeral places in one of key factors to find out internal structure of the city. However, there has not been, still now, even basic study or survey on the commercial centers in Pusan. Thus, this paper has the purpose to discover the spatial structure of the commercial centers of Pusan. For that, this paper has defined functions by the statistical data of 1981 and 1998 and has made Z-score by functions. As a result, enormous change has been discovered in the spatial distribution as well as hierachy of the commercial centers of Pusan between early '80s and late '90s, according to Z-score>1.

본 연구에는 CIS를 이용하여 장기유출 해석 모형의 하나인 NWS-PC모형의 매개변수를 얼마나 적절히 추정할 수 있는가에 대해 알아보았다. 수치표고모형, 수치토양도 및 인공위성영상을 분석하여 얻은 토지이용도 등을 기본 자료로 이용하였고 소유역별 특성값을 GIS를 이용하여 추출하였다. 이러한 특성치들은 Amstrong(1978)에 의거하여 소유역별 모형의 매개변수를 추정하는데 직접이용된다. NWS-PC 모형의 경우 추정된 매개변수는 가능한 값의 범위로 주 This study is to see how effectively the NWS-PC model parameters can be estimated using GIS. Basic informations such as DEM(Digital Elevation Model) ,digital soil map, land use information from satellite image are provided and analyzed for estimating the sub-basin characteristics in GIS. These charcateristics are used to estimate the model parameters for each sub-basin. The model parameters estimated based on Amstrong(1978) are given as a possible range, which will be fixed through the calibration procedure. In this study, we used the1974 data for calibration and the 1979 event for verification. From the calibration procedure, we could find that the parameters related with infiltration and water tend to have the minimum value of the range and that the parameters related with exfiltration of water tend to have the maximum value of the range This result seem to reflect the hydrologic characteristics of Keum-river basin, which could be used to fix the model parameter without difficult calibration procedure. The simulation results show that the relative error of calculated discharge to observed discharge to be within approximately 10% . Therefore, the model with the parameters calibrated was considered to be adaptable for long-term runoff analysisf or Keum-river basin.

There are many causes of trismus. Aetiology can be roughly divided into muscle spasm, mechanical interference, extracapsular ankylosis, intracapsular ankylosis. Trismus caused by mechanical interference between postero-lateral wall of zygoma-maxillary complex and coronoid process following reduction of fractured facial bone is rare. Especially on maxillary bone fracture, when we faced the trismus following removal of intermaxillary fixation, we got used to solve that problem by physical exercise, We obtained good resurts by coronoidectomy on patients with limited mouth opening who were referred from department of plastic surgery, St. Marys' hospital, the Catholic university of Korea. We report our experience with literature review.

This paper has tried to get hold of spatial distribution of land value in Pusan and an influence of land value on the various kinds of urban functions. Conclusions by the research are as follows. First, points of peak land value in Pusan are Kwangbok-Dong and Bujeon-Dong, and Kwangbok-Dong is greater than Bujeon-Dong in the influential zone according to just spatial present condition of land value. Second, specialized functional agglomeration and regional differentiation functionally are explicit in the region of Kwangbok-Dong. Third, functions having great correlation with land value are high quality retail, food and entertainment, cultural, and service function. Finally, functions having interdependent relation with many other ones are official, food and entertainment, service, and cultural function.

The District Unit Planning(DUP) system, which was introduced in the revised Urban Planning Law in 2000, is a policy instrument for specific planning in a special area in urban setting. The main purpose of this study is to find better DUP in Man-duk in Busan. Through comparing two plans ; One is planned low buildings in Man-duk, the other is planned high buildings in the same; in Man-duk. To compare these plans, the study suggested to consider the several criteria and landscape-simulations. By comparing two DUP in Man-duk, the second plan was better for residents than the frist. DUP system is concerned with improving the urban spatial quality, but we have recognised that DUP system has some problems. There are many various types in urban area which is needed DUP system. Finally, based on this study, urban areas need the flexible application of DUP for each type and is considered the correlations of area-specific and goal-specific features. 현행 지구 단위계획의 목적은 용도지역제의 의 문제점과 한계 를 극복하고 당해 지역 토지의 효율적 이용과 주민의 안정된 주거환경 도모는 물론 인접지역과 조화를 창출하자는데 있다. 지역이 지구단위계획에 의해서 개발되면, 토지의 입체적 이용, 지구 내 기능의 적정 배분, 도시설계 상 융통성 부여, 그리고 지구 간 조화의 도모 등에 있어 무리와 경직성이 최소화 될 수 있다. 이로부터 토지의 효율적 이용에 의한 난개발 방지, 경관보전, 그리고 지역전체의 안정된 공간구성의 극 대효과를 얻을 수 있다. 최근 들어 많은 지역에서 지구단위계획의 수립이 요구되고 있으며 그 대상과 범위는 상이하다. 그러나 지구단위계획의 운용실태를 살펴보면 차별적 계획목표의 부재와 천편 일률적인 계획요소의 적용으로 많은 문제점 이 나타나고 있다- 따라서 본 연구는 하나의 연구 사례대상 지역을 선정하고 이 지역에 어떤 형태의 주거단지가 개발되는 것이 지역 전체의 조화를 창출할 것인지 를 파악코자 한다. 또한 주어진 대상지의 내적 조건상 어떤 유형의 개발이 효율적 토지이용의 최선인가 를 밝히고자 한다. 이 과정상 바람직한 지구 단위계획의 방향도 모색될 것이다.

I have Studied spatial differences, similarities and characteristics between CBD and sub-CBD by depending on L.Q. Index method for each function, because the city of Pusan is the place where the growth of sub-CBD is clear as indistinct as discrimination between CBD and sub-CBD. Some conclusions that could be provided after I analysed spatial patterns of CBD and sub-CBD are that Seo-Myun is required for inducement of development that can support and respond incessant entering of new establishment in near future and it gets faced with stage that gets ready for future growth in the capacity of sub-CBD, and that Nam-Po is needed for improvement of new dimension for present space pressure.

A ten months old, female Yorkshire terrier weighing 2.88 kg referred to veterinary teaching hospital of college of veterinary medicine, Konkuk University because of syncope, cough and dyspnea. First hematological and serum chemical test revealed thrombocytopenia, mild anemia, and increase of concentration of ALP (195 U/L). On 57 days later, second hematological and serum chemical test revealed polycythemia, increase of concentration of ALP (211 U/L), and Tchol (387 mg/dl). Right atrium enlargement, main pulmonary artery bulge and cardiomegaly (VHS = 11.5) were observed in radiographic findings. Ultrasonographic images showed both right and left ventricular dilation and turbulent flow between the descending aorta and the main pulmonary artery in color Doppler imaging. ECG showed left ventricular enlargement, SA block, and electrical alternant. Thoracotomy was performed through left fourth intercostal incision under isoflurane anesthesia. Patent ductus arteriosus was double ligated with 1-0 silk. Cough and dyspnea disappeared on 5 days after operation. Turbulent flow was not found in color doppler imaging of ultrasonography on 10 days after operation. Ten months later after the operation, syncope could not exist any more.

The high coherence of laser beam has made it possible to observe interference effects even in the light scattered from rough surfaces. That's why, when object with a scattering surface is illuminated with laser light, we do see a speckled appearance due to random interference. This sort of unique property of laser speckle has brought into existence the new noncontacting techniques such as speckle metrology method of measuring deformation, displacement, and vibration etc of objects with high optical sensitivity. The measurable range of speckle metrology especially used to measure in-plane information, however, is limited by some factors, the so-called strain, rotation, tilt of surface and out of displacement perpendicular to the plane of analysis. This restrictions severly limits the measurable range of speckle metrology by causing the decorrelation of speckle patterns. It is the purpose of this paper to give a survey on the measurable limitation of speckle photography method that is one of speckle metrology. Namely we will discuss the mutual relationships and problems of each limitations adding the restriction of the largest and smallest displacement measurable with speckle methods.

The purpose of this study was to compare the diagnostic performance of Waters' and panoramic view ; maxillary sinus posteroanterior and lateral scanography of ?? for mucosal thickening of maxillary sinus as well as to identify the utility of ?? for the detection of maxillary sinus disease. The assessment was done at 66 maxillary sinuses in 45 patients and the results were as follows ; 1. Estimation of presence or absence of mucosal thickening. The sensitivity, specificity, and positive and negative predictive value of maxillary sinus posteroanterior and lateral scanography were 0.865, 0.860, 0.921, and 0.805 respectively and slightly higher than those of Waters' and panoramic views, which were 0.832, 0.835, 0.903, and 0.728 respectively. However, paired t-test showed no significant differences in the diagnostic performance of the two pairs of imaging modalities. 2. Estimation of the types of mucosal thickening. The diagnostic accuracy for type Ⅰ, Ⅱ, Ⅲ was 75.3% on Waters' and panoramic view ; 77.9% on maxillary sinus posteroanterior and lateral scanography. It was higher on the latter, but showed no significant differences from that on the former. 3. Reliability of interpretation. In intraobserver and interobserver agreement, both overall rates of agreement and kappa-value were slightly higher on maxillary sinus posteroanterior and lateral scanography than on Waters' and panoramic views. There was no significant differences between the two pairs of imaging modalities. These results suggested that scanogram is a useful diagnostic radiography as well as Waters' and panoramic views for detection of maxillary sinusitis.
