본 연구의 목적은 지식경영에 관한 이론담론의 검토를 통해 지식경영의 성공요인을 도출하고 지식경영의 성공사례를 분석하는 것이다. 사례분석은 해빙-변화-재동결이라는 변화관리 과정의 일반모델을 중심으로 지식경영의 성공요인들을 체계적으로 재분류한 것을 분석틀로 삼았다. 연구결과, 지식경영은 단순히 지식관리시스템의 도입만으로는 온전한 성과를 거둘 수 없으며, 조직구조의 변화, 구성원들의 행동양식과 사고방식의 변화 및 조직문화의 변화가 수반되어야 함을 결론내릴 수 있었다. 또 이러한 요인들의 통합적 인식에 기초한 실천을 위해서는 본 연구의 사례분석틀에서 제시된 변화관리 모델에 입각한 지식경영의 도입이 효과적인 것으로 판단된다.

In this paper, we designed, implemented and evaluated 32-bit CLA adder with the ENMODL(enhanced NORA Multiple Output Domino Logic) logic style which is new dynamic CMOS logic. The circuit is implemented using 0.8㎛ CMOS double-metal process technology. It operates stably and the addition time is less 3.9 ns. The ENMODL logic style can improve the performance in the high-speed computing circuits depending on the degree of recurrence.

최근 높은 수직정확도를 갖는 항공레이저측량 기술이 개발됨에 따라 이를 이용한 DEM(digital elevation model) 생성, 건물추출, 홍수위험지도 제작, 3차원 도시모델 구축 등의 다양한 연구가 활발하게 수행되고 있다. 본 연구에서는 항공레이저측량으로부터 취득한 원시자료로부터 생성한 해상도별 DEM의 표준편차를 계산하기 위해 점비교법, 등고선비교법 그리고 1/5,000 수치지형도를 활용하였다. 비교결과 점비교법이 등고선비교법보다 낮은 DEM 표준오차를 나타냈으며, 이것은 등고선비교법이 점비교법에 비해 조밀한 격자 연산이 이루어지지 않은 것이 원인으로 파악되었다. 또한 1/5,000 수치지형도는 평균수평거리인 25.4m 이하에서는 점비교법과 등고선비교법에 비해 높은 오차를 보였으며, 25.4m 이상에서는 등고선비교법과 유사한 결과를 나타냄을 알 수 있었다. As airborne laser scanning technique is developed with high vertical accuracy recently, there come many studies on DEM(digital elevation model creation, building extraction, flood risk mapping and 3D virtual city modeling. This study applied point comparative method, contour comparative method and digital map with scale 1/5,000 to calculate RMSE of DEM in according to resolution that was constructed using rawdata being acquired by airborne laser scanning. As a result, point comparative method showed lower DEM standard error than contour comparative method, it is a reason that contour comparative method was not carried out detailed grid calculation for point comparative method. Also, digital map with scale 1/5,000 showed higher DEM standard error than point comparative method and contour method in below 25.4m that is average horizontal distance among contour line, and showed similar result with contour comparative method in over 25.4m.

In the recent years, the importance of experience learning has been emphasized in the science education. Because of this situation, the science education that was mainly taught in the class has been changed into the field work. Therefore, the related teachers have recognized the systematic necessities of teaching materials that will be focused on the teaching places and activities. This study seeks to develop the study materials for the field geologic practice in the Snagjok-am, Deokmyeong-ri, Goseong-gun, Gyeonsangname-do, and to find the teaching methods for the geologic units of the earth science at the middle school. There are wide outcrop of sedimentary rocks which eroded by the sea waves in this place. And we have easily access to that place, so the field observation can be carried out successfully. Also there are various rocks, geologic structures, and fossils which are the importance materials for the science curriculum at the middle school. The practice course is divided into from A to E courses, and the related materials are made for the purpose of investigating those whole sites within one or two days. Each course can be explained as the followings. (1) Course A: participants can study from three stops the joint system of igneous rocks, the bedding layer of the sedimentary rocks, and the various characteristics of the shore sediments. (2) Course B: participants can investigate from three stops the structure of the sedimentary rocks, that is cross bedding, sun cracks and fossils. (3) Course C: participants can survey from two stops the various rock facies and geologic structure caused from the intrusion of igneous rocks. (4) Course D: in this course, students can observe the various aspects spontaneously because the previously stated geologic structures are repeatedly appeared. (5) Course E: participants can study the wave0cut bench, cliffs, and caves caused by the erosion of sea waves. This thesis seeks to develop the geologic informations, learning content, instructive and teaching methods, background knowledge, and the materials of field studies which students can effectively used. The content of field studies have focus on the geologic unit at the middle school science textbook, but this can be varied flexibly according to the related levels. Additionally, this study has been proven practically through the real experiments conducted by the first class student of the middle school. The conclusion is that the field programs have had the affirmative result in improving the scientific attitudes, and the cognition about field works has been appraised positively.

We have investigated the nuclear fuel state analysis from the physical characteristics of unclear fission products in the reactor core which are produced by reaction between neutron and U^235. We set up H which is the ratio of the number of defective fuel rod to the mass of tramp uranium and calculate the contributed rate of radioactivities of iodine isotopes in primary coolant. We have measured the radioactivities of fission products in the primary coolant of nuclear power reactor and utilized the ratios of radioactivities of I^131 to I^133 and I^135 to I^133 in order to calculate the number of defective fuel rod and the mass of tramp uranium. The ratio of the number of defective fuel rod to the mass of tramp uranium is more sensitive to variation of the number of defective fuel rod than to variation of the mass of tramp uranium. The model which is considered by the radioactivities of fission products released from the defective nuclear fuel and from the tramp uranium in the primary coolant is confirmed appropriateness.

워트프런트는 도심 및 내륙지역과는 다른 독특한 기후특성을 가지고 있으며 이를 고려하지 않고 개발할 경우 시설물의 하자발생, 에너지 및 유지관리비용의 상승을 초래하게 됨은 물론 배후지, 도시기후에 악영향을 미치게 된다. 본 연구는 부산지역의 10개 기상관측지점을 해안선에서 거리에 따라 워터프런트 및 내륙지역으로 분류하고 5년간의 기상데이터를 이용하여 워터프런트의 기후특성에 대해 검토한다. 또한 원터프런트지역임에도 내륙지역과 유사한 기후특성이 나타나고 있는 대연지점을 대상으로 기후특성변화의 원인에 대해 검토한다. The waterfront has distinct climate characteristics different from urban or inland area. These may create not only the rise of energy and maintenance costs for facilities located at waterfront areas, but also negative effects on the climate of the nearby inland area, unless these are treated with particular care. For the present study, the climate characteristics of waterfront were examined with climate data of 10 observation points carefully selected in Busan area. Each weather observation point was classified into either waterfront area of inland area, based on the distance from the coastal line. Special considerations were given to the climate data gathered at the Dae-Yeon weather station because it shows the climate characteristics similar to those of inland area although it is located very near the waterfront area. Results indicates that this peculiar climate condition attributes, at least in part, to the reclamation of frontal coastal area.

This paper is intended as an introduction to the principles and computer simulation of parallel beam image reconstruction which may be classified as radon transform and circular convolution. The radon transform is a mapping from two dimensional image domain to a parameter domain. Therefore, high speed and data compression has been obtained. The radon transform leads to the projection or central slice theorem through a one dimensional or two dimensional fourier transform. The inverse radon transform can be implemented by filtering the projections in the fourier domain and back-projection. Circular convolutions are usually evaluated via FFT(fast fourier transform). The fast convolution advantages of this technique are that it is more efficient than the well-known fourier transform.
