This thesis is aimed at leading a sound society by means of healthy leisure activities in the Korean societies. For this purpose, first, I approached to understand students' leisure activities, and then tried to reduce the obstacles of their activities through analyzing their causes. This approach will be achieved by teaching college students healthy and desirable leisure activities in Korean societies; and as a long-term purpose, it will guide sound leisure activities on the level of permanent education. In this thesis, I approached the obstacles of college students' leisure activities through (one-way Anova). And I categorized the causes of their obstacles into eight units: lack of time, lack of money, lack of information, lack physical activity, lack of volition, obstacle caused by college study, lack of leisure facilities, and lack of the opportunities of leisure activities. And I focused on the students' sex, grade, average monthly pocket money, income of their families, and their fathers' schooling as the responding college students' background characteristics. The results of the analyses are as follows: 1. According to the results of sex analysis, female students showed fewer leisure activities than male students on account of their less physical strength. It was revealed that the female students have a significant difference by the level of p<.05. And the female students also had fewer opportunities of leisure activities than male students, which revealed the significant difference of p<.05. 2. According to the results of grade analysis, it was revealed that lower grade students(freshmen) have limitations of leisure activities on account of their less information, and the result was the significant difference p<.01. 3. According to students' leisure activities based on family income, in the case of the students who are from lower than 1 million won monthly family income, they showed the limitation of leisure activities on account of lack of money and there was a significant difference of p<.05. And the limitation of leisure activities on account of lack of information revealed a significant difference by the level of p<.05, 4. The obstacles of students' leisure activities based on fathers' schooling showed the results that in case that fathers' schooling was college drop out or junior college graduation, their lack of information was the cause of a significant difference by the level of p<.05. However, the difference of students' pocket money was not the cause of a significant difference. The research result of this thesis concluded that in order to solve the problem of obstacles of students' leisure activities, in case of female students, we need to intensify their physical strength; and in case of freshmen, it is required to provide them with more various kinds of information of leisure activities. However, in case of the students from lower income families, for their desirable leisure activities, colleges or societies should show the students more concern and give them various opportunities of free leisure activities instead of monetary aid. Despite fathers' lack of schooling, when colleges or societies provide more various kinds of information of leisure activities, students will enjoy more sound and desirable leisure activities. The insufficient advanced researches gave this thesis much difficulty. However, I expect that continuous researches and studies of this area will lead to great scholarly development in the aspect of the permanent education.

We propose a statistical algorithm which is applicable for speaker recognition and identification. The decision logic is formulated by computing the correlation coefficient between two speakers based on the LPC Log Spectrum and the LPC based Cepstral Spectrum of the speech signals. We tested the algorithm with Korean word "Sung Kyun Kwan" spoken by 11 male speakers, which is sampled at 16KHz rate and quantized to 16 bits. The test result showed very high recognition rates(94.5% for the case of LPC Log Spectrum and 98.2% for LPC based Cepstral Spectrum), whereas the conventional DTW algorithm based on the pitch contours of the speech signal had a relatively low recognition rate(89%). In addition to the recognition rate, the correlation method outperformed the DTW method in processing time as well, i.e. it requires much less computation load than DTW. Thus the proposed algorithm seems to have a strong potential to be applied to the areas where very high recognition rates as well as real time processing are required such as a security control system.

압축성을 고려한 분율 흐름 접근 방식에 근거한 삼상흐름모델 개발

석희준,고경석,Suk, Hee-Jun,Ko, Kyung-Seok,Yeh, Gour-Tsyh 대한자원환경지질학회 2008 자원환경지질 Vol.41 No.6

대부분의 분을 흐름 접근 방식을 따르는 다상흐름모델들은 주로 유체나 매질의 비 압축성을 가정하거나 완전한 삼상 오염물을 다루지 않고 이상 유체 (물 또는 공기, 물 또는 불용융성유체)의 거동만을 다룬다. 그러나 본 연구에서는 유체 및 매질의 압축성과 완전한 삼상 오염물을 가정하는, 분율흐름접근방식을 따르는 수학적 지배방정식을 개발하고, 이를 토대로 압축성 유체 및 매질을 고려한 삼상흐름 수치모의프로그램을 개발하였다 개발된 삼상흐름 수치모의프로그램 (Compressible Multiphase Flow Simulator, CMPS)을 검증하기 위해서 기존에 개발된 비압축성 유체 및 매질을 고려한 삼상흐름수치모의 프로그램인 MPS (Suk and Yeh, 2007; Suk and Yeh, 2008) 및 해석해를 통해서 간접적으로 비교 검증하였다. 비교결과 CMPS와 MPS의 결과와 해석해들은 서로 잘 일치하였다. 따라서 CMPS는 압축성 유체 및 매질을 고려한 삼상흐름 수치모의를 구현 할 수 있는 가능성을 가진다. Most multiphase flow simulators following fractional flow approach assume incompressibility of fluid and matrix or consider only two phase flow (water and air, water and NAPL). However, in this study, mathematical governing equations were developed for fully compressible three-phase flow using fractional flow based approach. Also, fully compressible multiphase flow simulator (CMPS) considering compressibilities of matrix and fluid was developed using the mathematical governing equations. In order to verify CMPS, the CMPS were compared with analytical solution and the existing multiphase flow simulator, MPS, which had been developed for simulating incompressible multiphase flow (Suk and Yeh 2007; Suk and Yeh 2008). According to the results, solutions of CMPS and MPS and analytical solutions are well matched each other. Thus, it is found that CMPS has the capability of simulating compressible three phase flow phenomena assuming compressibilities of fluids and matrix.

Impact of the Indian Ocean on ENSO variability in a hybrid coupled model

Yeh, Sang-Wook,Wu, Renguang,Kirtman, Ben P. John WileySons, Ltd. 2007 Quarterly journal of the Royal Meteorological Soci Vol.133 No.623

<P>This study examines the impact of the Indian Ocean on El Niño and the Southern Oscillation (ENSO) variability through a series of numerical experiments with a hybrid coupled model. In the control run, an atmospheric general circulation model (AGCM) is coupled to the Zebiak–Cane simple ocean model in the tropical Pacific. Outside the tropical Pacific climatological sea surface temperatures are prescribed in the control simulation. In the first experiment, sea surface temperature anomalies (SSTAs) in the Indian Ocean are statistically predicted based on the state of the Pacific, and used to force the atmosphere. In the second experiment, a slab thermodynamic mixed layer model is coupled to the AGCM in the Indian Ocean. The Indian Ocean modifies the ENSO frequency via interactions with the Indian monsoon, but only when air–sea interactions in the Indian Ocean are included in the experimental design (i.e. the second experiment). The inclusion of the Indian Ocean, however, has little impact on the ENSO amplitude, which is at variance with other coupled simulations, suggesting that some missing dynamics or physics (i.e. Indian Ocean dynamics, Indonesian Throughflow, etc.) may play an important role. The Indian summer monsoon is more tightly coupled to ENSO in the second experiment than in the control run and the first experiment. The power spectrum of the Indian monsoon rainfall has a significant biennial time-scale of around 20–30 months in the second experiment, which may enhance the biennial time-scale of ENSO variability through a shift of the horizontal structure of zonal wind stress variability in the central equatorial Pacific.

Analysis on the Friction Losses of a Bent-Axis Type Hydraulic Piston Pump

Yeh-Sun Hong,Yoon-Ho Doh 대한기계학회 2004 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.18 No.9

he design of an axial piston pump for electro-hydrostatic transmission systems requires accurate information where and how much the internal friction and flow losses are produced. This study is particularly focused on the friction losses of a bent-axis type hydraulic piston pump, aiming at finding out which design factors influence its torque efficiency most signiTo this end, the friction coefficients of the pump parts such as piston heads, spherical joints, shaft bearings, and valve plate were experimentally identified by a specially constructed tribometer. Applying the experimental data to the equations of motion for pistons as well as to the theoretical friction models for the pump parts, the friction torques produced by them were computed. The accuracy of the computed results was confirmed by the comparison with the practical input torque of the pump. In this paper, it is shown that the viscous friction forces on the valve plate and input shaft bearing are the primary source of the friction losses of the bent-axis type pump, while the friction forces and moments on the piston are of little significance.
