        이원표,안덕철,김희석 청주대학교 산업과학연구소 2000 産業科學硏究 Vol.17 No.2

        In this paper, designed a high speed 2-dimensional DCT(Discrete Cosine Transform) design using the distributed arithmetic system applicable to MPEG, JPEG, H26x system for image data compression. This system is using the DA, vector processing and pipeline. Designed in this paper, consists of datapath unit and controller. This system is compared to the pipelined 2-D DCT. As the result, This system processes 12 frames/sec for 720 × 480 size, therefore, that This system is prior to pipelined 2-D DCT system was found.

        이원표,부기원 江原大學校附設體育科學硏究所 2004 江原大學校附設體育科學硏究所論文集 Vol.- No.27

        The purpose of this study was to survey and analyze the response of civil servants on the participation in sports activities and the cause of barrier in sprots participation with 400 civil servants (female:100, male:300) on the Yangpyong city in Kyongki province were answered by the questionnaire. Analysis of the data with 376(female:90, male:286) for the evaluation of the questionnaire can be acquired the more basis materials of sports environment for the civil servants. As result, we have the conclusion as follow. 1. The participation in sports activities among civil servants. The servey of the participation in sports activities among civil servants is as follows. The frequency of playing sports is 1∼2 in a week. The time last 30min.∼1hr. The preferance time is in the aftermoon. The major reason of playing sports is promotion of health. The most popular sports is jogging and marathon. 2. The cause of barrier in sports participation among civil servants is as follows in order. 1) Dissatisfaction of sports program 2) Difficulty of approach to sports club 3) Insufficiency of social support 4) Shortage of time 5) Low nterest in sports 6) Enerfation 7) Shortage of physical strength.

        The purpose of this study was to survey and analyze the response of middle, high-school students on the barriers to exercise and sport with 600 students(male:330, female:270) on the yangpyong city in kyongki province were answered by the questionnaire. Analysis of the data with 565(male:311, female:254) for the evaluation of the questionnaire can be acquired the more basis materials of sports environmnet for the middle, high-school students. As result, we have the conclusion as follow. 1. In their sex and factor of sport barriers. male is a bar to according to priority sport program(3.05), sport club(3.00), financial support(2.91), social support(2.85), time shortage(2.73), different concern(2.34), enervation (2.13), health/physical strength(2.03) female is a bar to according to priority sport program(3.30), sport club(3.04), time shortage(2.96), different concern(2.95), social support(2.88), financial support(2.84), enervation (2.59), health/physical strength(2.14) 2.

      • 상위 수준에서의 MDCT/IMDCT 구현

        이원표,김희석 청주대학교 산업과학연구소 2005 産業科學硏究 Vol.22 No.3

        In this paper, we implement the Modified Discrete Cosine Transform(MDCT)/Inverse MDCT(IMDCT) in MPEG audio layer 3 using HW(Hardware)/SW(Software) Co-Design methodology. The computation process of the MDCT/IMDCT is most intensive in MPEG audio layer 3. Therefore, it is very important that the MDCT/IMDCT must be implemented in HW. The eXCite in YXI Co., which inputs ANSI-C language as high-level description and outputs VHDL or(and) Verilog-HDL file in HW/SW Co-Design. As the result to simulate our design, the MDCT/IMDCT are operated in 68MHz on Stratix chip in ALTERA and in 20MHz on Excalibur chip for SoC Design

        Dubin - Johnson 증후군 10예에 대한 임상적 고찰

        이원표,윤용범,김정용 대한소화기학회 1980 대한소화기학회지 Vol.12 No.1

        The Dubin-Johnson Syndrome is characterized by chronic, mild, predominantly conjugated hyperbilirubinemia with a blcak liver and pigmentation of parenchymal liver cell. The disorder result from an inherited abnormality in the excretion of various non-bile salt organic anion from the liver cell into the bile. It is benign non-progressive and not associated with any form of chronic hepatic or biliary tract disease. The diagnosis of the Dubin-Johnson syndrome is established by secondary rise in BSP retension test and needle biopsy of the liver. The important consideration in managing patient with this disorder are the reassurrance that the abnormality is benign and leads to no disability or reduction in life expectancy and the avoidance of unnecessary biliary tract surgery. Clinical observation was made on 10 cases of Dubin-Johnson Syndrome admitted to department of internal medicine, Seoul National University Hospital from 1969 to 1979. The following results are obtained 1. The male to female ratio was 6: 4 and the majority of the cases are in 3rd decale. 2. There were 3 cases of jaundice on family history and 2 cases were brother and sister relationship. 3. The chief complaints on admission were in order of jaundice, latigue, right upper abdominal gain and dark urine. 4. Hepatomogaly was observed in 5 cases, but there was no case of splenomegaly. 5. The average serum total biliubin level was 2.98±1.29mg/100ml and the average serum conjugated bilirubin level was 1.76±0.04mg/100ml. Other liver function tests revealed normal values. 6. HBsAg and αFP test were performed in 5 cases and the results were negative in all cases. 7. Oral cholecystography was performed in 6 cases and the gallbladder was visualized in 8 cases, suggesting that the important non-visualization of gall-bladder on oral cholecystography for the diagnosis of the disorders ought to be reconsidered.
