        記錄社會身分稱謂的君,臣二字所貯存的文化意蘊

        유흥균,이점평 영남중국어문학회 2013 중국어문학 Vol.0 No.64

        Jun(君) and Chen(臣) often appear in pairs in ancient literature. Jun is combined with 尹and 口. The structure of 臣 resembles a capture staring in anger. The 尹 in 君shows a person seizing power while means both giving commands and taking in criticism. Therefore, 君 is restricted by ceremonial behavior standards when endowed with great power. 臣, on the other hand, even evolves from war capture to court slaves, then to administrators of state affairs, still remain to be subjects to monarch. In Confucius philosophy, does not refers to blind loyalty, but the brave spirit of making right suggestions without fears of offending royalty.

        中国古代礼仪禁忌的性质、功能及其当代价值

        유흥균 동아인문학회 2014 동아인문학 Vol.28 No.-

        Taboo between Chinese etiquette and western culture share similarities such as taboo to impurity and sacred matter and avoidance to punishment by supernatural forces. However, Chinese etiquette taboos have a stronger sense of ethics and integrity and richer culture features. They play social roles to guide people into integrity, social hierarchy, and proper human relations and prevent promiscuousness and disasters. By thorough study, we can apply ancient standards to modern days and propose manners that both in line with the modern spirit and ancient criteria. It is of great significance as to cultivate the goodness among citizens, promote modern civilization and construct socialist value system. 中國古代禮儀禁忌與西方“taboo”有相似之處,同樣有對不潔和神聖事物的禁忌,有避免超自然力量懲罰的功利目的,但更體現出強烈的道德倫理色彩,具有濃厚的禮儀文化特徵,有著正言行、嚴尊卑、明人倫、防淫亂和避禍害等社會功能。對其進行深入研究和整理,挖掘出能“古為今用”、與時代精神吻合的言談舉止規範,對於培養公民“明禮誠信”的文明素質,促進精神文明建設,構建社會主義價值體系等有著重要的借鑒意義和價值。

        유흥균,임성준,유호진 충북대학교 산업과학기술연구소 1996 산업과학기술연구 논문집 Vol.10 No.2

        Anionic oligomer surgactants, dodecyl polyoxyethylene α-sulfo alkanoates, had been synthesized through the esterification of dodecyl polyoxyethylene ether and α-sulfo alkanoic acid with straight chain alkyl group having from 10 to 18 carbon atoms to good yield Surface tension of sodium dodecyl polyoxyethylene α-sulfo alkanoates aqueous solution were measured and critical micelle concentration was evaluated. Their cmc evaluated by the surface tension method was 10^(-4) ∼10^(-5) ㏖/ℓ and surface tension of the aqueous solution was decreased to 30∼47dyne/cm, showed the tendency that the ability of lowering the surface tension was depending on the increase of carbon atom number in the hydrophobic alkyl chain. In micellization, the contribution of standard free energy change per methylene group in the molecule have been found to be -0.23/RT∼ -0.32/RT, and the process have been proceeded by entropy control process in the range of 15∼45℃ spontaneously.

      • 디지탈 변조 기능이 있는 주파수 합성기 설계 연구

        유흥균,김남일 충북대학교 산업과학기술연구소 1997 산업과학기술연구 논문집 Vol.11 No.2

        Conventional direct digital frequency synthesizer(DDFS) has been analyzed and we construct the circuit configuration to simulate and certify the functional performances. The digital frequency synthesizer is proposed to have the 4-psk modulation function, which is very important to implement the FH/PSK modulation system. To design and verify the aimed operation of logic circuit, the existing standard cell library and a specific design system of FPGA(Quick_Logic) and P-SPICE tools are used. In proposed DDFS with PSK modulation function, output sine waveform can be obtained according to frequency control input data or system clock, and QPSK(Quadrature Phase Shift Keying) phase modulation function is easily performed that can transmit four phase-modulated signals.

        The purpose of this study is to design and implement the simulated Syntax Directed Editor (SDE) system for basic programming instruction. this study to develop learning strategies for the activities with computer simulation, and to suggest the practical use of computer simulation for the activities for computer programming learner. SDE trace first program which student was programmed, and then give simulation environment on screen especially using variable list. By this, the student can simulate the procedure of variables in their own program and control the learning speed and cycle according to their ability.

      • 효과적 무선 데이터 전송을 위한 Hybrid ARQ 방식 연구

        유흥균 충북대학교 산업과학기술연구소 1999 산업과학기술연구 논문집 Vol.13 No.1

        The performance of SR ARQ and conventional Type-Ⅰ Hybrid ARQ with fixed code rate are investigated by using the parameters of packet length, channel capacity, BER, and transmission delay time especially. BCH code is used in Type-Ⅰ Hybrid ARQ for FEC method. This paper presents the throughput analyses according to such various parameters as BCH code rate, window size, data rate and round-trip delay time. Also, the performance of Type-Ⅰ Hybrid ARQ considering transmission delay time is analyzed through numerical analysis and computer simulation so we can get a important characteristics variation.

      • 4-PAM/FM 변조 방식의 ERMES 수신회로 설계와 BER 성능분석

        유흥균,정은택 충북대학교 산업과학기술연구소 1993 산업과학기술연구 논문집 Vol.7 No.2

        In this paper, a syntactic approach for the recognition of handwritten numerals using array grammars is described. Core array grammars and augmented array grammars for each numeral are made and 2-PASS array parser is constructed for augmented array grammars. 128 × 128 input image is scaled down 32 × 32 binary pattern and scaled binary pattern is thinned and the noise is reduced. In the 2-PASS array parser which parses the processed pattern, PASS-1 measures the distance of substitution, deletion and insertion error transformation for augmented array grammars. If the parsing result of the PASS-1 turns out to be an erroneous recognition, PASS-2 will measure the distance of all error transformations for extended insertion error transformation. Because the array parser directly parses the 2-dimensional arrays, this procedure does not require 2-dimensional arrays to be encoded into 1-dimensional strings. As the results of experiment, recognition rate for 146 handwritten numerals is 95.2% and recognition time in IBM PC/AT is about 0.84 seconds.

        OFDM 통신 시스템에서 더미 시퀀스를 추가하는 SLM 기반 실시간 PAPR 저감 방식

        유흥균,Ryu Heung-Gyoon 한국통신학회 2005 韓國通信學會論文誌 Vol.30 No.4A

        OFDM(orthogonal frequency division multiplexing) 통신 시스템은 고속 무선 데이터 전송에 적합한 방식으로 널리 알려져 있지만, 높은 PAPR(peak-to-average power ratio)로 인하여 HPA(high power amplifier)에서 큰 비선형 왜곡을 겪는 문제점을 갖는다. 본 논문에서는 이러한 높은 PAPR을 저감하는 방법으로 더미 시퀀스(dummy sequence)를 삽입하는 새로운 SLM (selective mapping)방식을 제안하며, 이를 DSI-SLM기법이라 하기로 한다. 제안된DSI-SLM 기법은 각 브랜치(branch)에서 일정비율의 부반송파에 각기 다른 더미 시퀀스를 인가하고 IFFT(inverse Fourier transform) 후 가장 낮은 PAPR을 갖는 브랜치의 데이터를 전송한다. 이 방식에 사용된 더미 시퀀스는 송신단에서 PAPR 저감만을 위해 사용될 뿐 수신단에서의 데이터 복원 과정에는 필요로 하지 않으므로, 기존의 SLM및 PTS에서 나타나는 부가정보 전송의 필수성과 같은 단점을 해결하면서 실시간 데이터 처리를 가능케 한다. OFDM communications system is very attractive for the high data rate wireless transmission. However, it may be distorted in the nonlinear HPA since OFDM signal has high PAPR. So, a new SLM method using dummy sequence is studied for reducing the PAPR, and we call it DSI-SLM method. Unlike the conventional SLM method using the phase rotation, dummy sequences for PAPR reduction are assigned at the predefined sub-carriers. After IFFT, the OFDM data signal of the lowest PAPR is selected to transmit. So, it can cut down the computational complexity because it does not require the transmission and demodulation process of side information about the phase rotation. This proposed method can solve the time delay problem so that PAPR reduction can be made in real time processing.
