The area around Naktong river Basin may be divided into two hydrogeologic provinces on the basis of hydrolic boundary analysis. The hydrogeologic provinces are named as Naktong and Silra hydrogeologic provinces by the writers. The Naktong hydrogeologic province locates at the west and north west side of Naktong River, whereas silra hydrogeologic province locates at the east side of Naktong River. The Naktong hydrogeologic provinces consists of upper-Naktong river, Naesungcheon, Songyacheon, yungcheon, Namcheon, Kamcheoon, Baekcheon, Hecheon, Hwangcheon, and Namgang Groud water system. The silra hydrogeologics province consist of Banbyencheon, Micheon, Uicheon, Suensan, Kumhogang, Changnyeng, milyangcheon, and under Naktong river Ground water systems. This paper entitled "The Hydrogeologic Study of Naktong River Basin" emphasizes the ground water movement within kamcheon and Sangjoo Namcheon river basin Ground water System. The studied system consists hydrogeologically of the consolidated rocks and unconsolidated deposits. The groundwater within the consolidated rocks (Granite and Gneissose rock) is Neglible for us to use it. Accordingly, The writers mainly study groundwater within the unconsolidated deposits. The unconsolidated deposits consists in some detail of Sedentary and Alluvium deposits. The coefficient of permeability in the Sedentary deposits is so neglible that the writers again exclude it from ground water category in the system. The writers finally limit their detailed study to the Alluvium deposits. The boring data from Aquifier and detailed geology within the Alluvium deposit were carefully discussed and studied at the stand point of Ground water movement and concluded as the followings: (1) The amount of under ground water is not dependent on the depth of each layer but on its permeability coefficient. (2) The sedentary deposits of Granitic rocks are the most favorable reservoir of nderground water among the wide sedentary deposits. (3) The classification of the layers according to the size of their materials is very useful for the calculation of permeability coefficient. (4) The practically applicable radius of influence circle of the study area is nearly equal the half to that of their formula. (5) The seven ground water areas within kamcheon river basin groundwaters system from grownd water dome, and ground water basin. However, the ground water over the whole system is considered to be closer to Artesian water rather than ground water. (6) The speed of ground water flow range 1.4㎝/H to 190.57㎝/H. The average would be 25㎝/H. The ground water flows so slowly that it would take considerable time before the water gathers after discharge.

The purpose of this study was to investigate the effects of bowling exercises on gait pattern and posture students with mental retardation and social interaction with students without disabilities. The videography method was used to obtain kinematical variables of gait pattern for pre & post tests of bowling exercises. The posture of students with mental retardation and interaction with students without disabilities were recorded onto video tapes. Analyzing the recorded data from all experiments led to the following conclusions: irregular gait pattern and posture of the students with mental retardation can be corrected or improved substantially through bowling exercises. And the inclusive exercises program with students without disabilities can show the model appropriate behavior, encourage social interaction, and promote positive self-esteem to the students with mental retardation.

Inputting data of human motion analysis means signal processing of changes in linear time dependent spatial coordinates of anatomical landmarks. Commercial CCD camera appears to be sampling 30 fps imposing limitation for human motion analysis which needs at least 60 fps. For the interpolation 60 fps fast algorithm of inverse wavelet transformation (IWT) was utilized producing 60 fps out of normal 30 fps. The original data from free fall and cycling motion of lower extremity were used to test the applicabiility of wavelet interpolation to human motion analysis. The test results showed linear relationship between two data sets. In the test of free fall, data curves of two sets, theoretical 30 frame data and 60 frame data after inverse wavelet transformation, appeared to be almost identical. Regression analysis of free fall test showed R^2 = 0.99 meaning Y = IWT. In the test with cycling motion of lower extremity % cycle of maximum flexion and extension at the joints was compared between two data sets showing same result, as in free fall test.

FAN용 외전형 BLDC전동기 설계 및 특성해석

윤선기,박영일,이광호,조윤현 東亞大學校 1999 東亞論叢 Vol.36 No.-

Permanent magnet brushless motors are increasingly being used in high performance applications. The advantage of using a BLDC motor is that is can be controlled to have the speed-torque characteristics similar to that of a permanent magnet DC motor. In addition, the BLDC motor has low ineria, large power to volume ratio, and low noise as compared with the permanent magnet DC servo motor having the same output rating. This paper is proposed the design method of Outer Roter BLDC for a blower fan by the magnetic equivalent method. In order to compute and estimate the performance parameter of Outer type BLDC, the dynamic model and charateristics analysis of BLDC is simulated by Matlab.

A new technique is presented for analysis of the magnetic fields produced by color television deflection yokes. This method is proved to give the results as accurate as those obtained by conventional finite-difference method in the calculation of the magnetic filled. More over, the computation algorithms using this method have been found to be move computationally efficient than existing finite-difference programs.

재인 오스틴 소설의 특성

徐永琪 忠州大學校 1968 한국교통대학교 논문집 Vol.2 No.-

19세기 영국이 낳은 위대한 여류작가 Jane Austen은 Richardson 및 Fielding 이후 당시 낭만주의의 거센 물결에 휩쓸려 침체일로를 걷고 있던 영국 근대 전통 사실 문학을 소생시켜 이를 계승발전 시킨 작가로서 영국 소설을 기술적으로 일약 전진 시켰음은 물론 당시의 퇴폐된 낭만적 사상을 박차고 사실주의를 택하므로서 영국적 전통 문학의 제일인자가 되어 후대 George Eliot, Henry James, Virginia Woolf, E.M. Foster 등 무수한 문학가들의 앞길을 개척해준 작가로서 영문학 사상 특기 할만한 거성적 존재이다. 한때 문학 평론가 매큐리 경에 의하여 세익스피어와 대등한 위치로 까지 비평된바 있는 Jane Austen의 존재는 많은 비평가들의 연구대상이 되었거니와 근년에 이르러 새삼 그녀와 그녀의 작품에 대한 연구들은 점증 고조되고 있는 실정이다. 그녀가 남긴 6편의 작품중 최대 걸작으로 알려진 Pride and Prejudice와 Emma 속에 나오는 작중 인물의 묘사, 주제, 작품구성 및 문체등의 연구를 통해서 그녀의 작품과 작품의 본질 그리고 전반적 특성을 구명하므로서 그녀의 영문학사상에 남긴 업적과 작가로서의 위대성을 평가해 보려는 것이 본 논문의 시도이다.

DC 마그네트론 스퍼터링법으로 제조된 코발트 박막에 대해 증착속도 및 미세구조에 미치는 스퍼터링조건의 영향을 조사하였다. 증착속도는 투입전력이 커질수록 증가하였으며, 아르곤 압력이 커질수록 감소하였는데, 이는 투입전력의 증가로 인한 타게트 표면의 이온전류 밀도의 상승과 Ar 압력증가에 따른 비산효과의 증대로 인한 타게트 표면의 이온 전류 밀도의 감소로 고찰되었다. 투입전력이 커질수록 결정립의 크기가 감소하였으며, 투입 전력에 관계없이 특정한 면이 발달하지 않는 비정실 구조를 나타내었다. Ar 압력에 관계없이 비정질 구조를 나타내었다. We have investigated the influence of sputtering condition on deposition rate and microstructure of Co thin film produced by the method of DC Magnetron Sputtering. Deposition rate increased with the input power due to the rise in ionic current density on the surface of target, and decreased with the pressure of Ar gas due to the decrement of ionic current density by the effect of diffusion. Microstructure of the Co thin film became a finer structure with the increase in the input power, and showed amorphous irrespective of the charge of the input power and the pressure of Ar gas.
