戱曲 「山돼지」 硏究

김성진(Kim Sung-jin) 중앙어문학회 2000 語文論集 Vol.28 No.-

This dissertation deals with Kim Woo-jin's 「Wild Boar」. Kim Woo-jin became indulged in his art during his University education. What's more, he tried to express the theatre art through a sharp insight of the times and created an optimistic atmosphere for Koreans under Japanese rule. His father, Kim Sung-kyu, was a president of the 'Mokpo Literary Association' and enjoyed writing poems. He also had such a special affection for literature that he contributed lots of money to support the 'Mokpo Literary Association'. And the world of death in Kim Woo-jin's works does not mean a real death. The world suggests the death of Korea traditional and conservative customs and reflects the difficult reality to break the traditional customs. His leaving home to lead a spiritual life carried on the very important meaning. 〈Noon〉 deals with the consciousness of class and nation, and 〈Lee Young-yeo〉 criticizes the defect of masculine centered society through Lee Yong-yeo. According to 「The Disgust of Poet Dooduckee」 and 「Shipwreck」 represent Kim Woo-jin's self conscious drama and the words of disgust and wreck symbolizes Kim Woo-jin's self desire for a new world. 「Wild Boar」 represents the free society for all people and the social awareness for reform. Kim Woo-jin includes the 'Dong Hak movement' in his drama and suggests a uncompromising willingness of social revolution established by young intellectuals and himself who showed only conscious conflict within the predestined yoke of the individual. In the play he changed his dramatic techniques which brought him closer to his readers and audiences but he emphasized intellectuals' awakening in much of his work. In other way, Kim Woo-jin developed a new contemporary drama movement in Korea for the nation which might have expressed real life under Japanese colonial rule. Kim Woo-jin was the representative of Korean drama in the 1920's who lived as a poet and critic as well as a experimental playwriter. Kim Woo-jin was one of the most excellent dramatists and the forerunner of Korean modern literature who led the new theatre movement, developed Korean drama from the early literature stages of the 1920's, and established himself as a leader in Korea literature.

전역통과 시스템에 대한 Deconvolution 필터링 기법

김성진,Kim Sung-Jin 한국정보통신학회 2006 한국정보통신학회논문지 Vol.10 No.6

본 논문에서는 FIR 근사를 기반으로한 전역통과 시스템에 대한 deconvolution 필터링 기법을 제안한다. 제안한 기법은 안정한 non-causal deconvolution 필터를 FIR 근사에 의해 안정한 causal deconvolution 필터로 변환시키는 것이다. 본 논문에서 보인바와 같이 전역통과시스템에 대한 deconvolution 필터의 임펄스 응답은 전역통과 시스템 자체의 임펄스 응답의 거울 영상(mirror image) 임을 알 수 있다. 이와 같이 전역통과 시스템에 대한 임펄스 응답과 그 시스템의 deconvolution 필터에 대한 임펄스 응답의 대칭성 때문에, 제안한 기법은 전역 통과 필터의 차수에 상관없이 동일하게 적용할 수 있다. 제안한 기법의 성능을 보이기 위하여 1차, 2차 및 400차의 전역통과 시스템에 대한 컴퓨터 시뮬레이션 결과를 포함한다. In this paper, a deconvolution filtering method for all-pass systems based on FIR approximation is proposed. The proposed method enables us to obtain a causal stable deconvolution filter by FIR approximating a non-causal stable deconvolution filter to a causal stable one. As we can see in this paper, the impulse response of the deconvolution filter for all-pass system is simply the mirror image of the impulse response for all-pass system itself. Due to this symmetric property between all-pass system itself and its deconvolution Inter, this method can be applied to all-pass systems without special limitation of the system's order. In order to verify the performance of the proposed method. computer simulation results for 1st-, 2nd- and 400th-order all-pass systems are included.

김성진,Kim, Sung-Jin 한국진공학회 2011 Applied Science and Convergence Technology Vol.20 No.4

약밀려남/잡아당김/급냉각의 연속적인 압출 공정을 이용하여 대면적 불화 고분자 막을 제작하였다. 제안한 방법으로 형성된 불화 고분자 박막은 $C_i=2.9\;nF/cm^2$의 전기용량밀도가 측정되었고, 1kHz에서의 ${\varepsilon}_r$=56의 높은 유전상수를 나타내었다. $1.5406{\AA}$의 파장에서 Bruker AXS X-ray 회절분석기를 통해 $18.0^{\circ}$에서 최고점을 나타내어 전기변형 성능에 적합한 ${\beta}$ 상태를 확인하였다. 본 연구는 넓은 면적의 인공근육에 응용 가능한 전기변형 불화고분자막의 새로운 박막 형성 기술로 이용될 수 있다. Polymer electrostrictor materials can exhibit high electroactive strain and hold increasing promise for a variety of actuator applications. The size of available actuators has been limited, however, by the solution-based casting and annealing process generally required to prepare electrostrictor actuator materials. We report on a high throughput melt and stretch extrusion process capable of creating large sheets of an electrostructive terpolymer, poly (vinylidene fluoride-trifluoroethylene-1, 1-chlorofluoroethlene) while producing a suitable crystallinity and crystal phase for high strain electrostrictor performance such as artificial muscle systems.

해양환경용 알루미늄 합금 재료의 전기화학적 부식 손상 특성

김성진,황은혜,박일초,김성종,Kim, Sung Jin,Hwang, Eun Hye,Park, Il-Cho,Kim, Seong-Jong 한국표면공학회 2018 한국표면공학회지 Vol.51 No.6

In this study, various electrochemical experiments were carried out to compare the corrosion characteristics of AA5052-O, AA5083-H321 and AA6061-T6 in seawater. The electrochemical impedance and potentiostatic polarization measurements showed that the corrosion resistance is decreased in the order of AA5052-O, AA5083-H321 and AA6061-T6, with AA5052-O being the highest resistant. This is closely associated with the property of passive film formed on three tested Al alloys. Based on the slope of Mott-Schottky plots of an n-type semiconductor, the density of oxygen vacancies in the passive film formed on the alloys was determined. This revealed that the defect density is increased in the order of AA5052-O, AA5083-H321 and AA6061-T6. Considering these facts, it is implied that the addition of Mg, Si, and Cu to the Al alloys can degrade the passivity, which is characterized by a passive film structure containing more defect sites, contributing to the decrease in corrosion resistance in seawater.

김성진,박용진,Kim, Sung-Jin,Park, Yong-Jin 대한전자공학회 1999 電子工學會論文誌-T Vol.t36 No.4

화상회의 시스템은 지리적으로 분산된 컴퓨터 사용자들이 회의 시스템을 공유함으로써 오디오 및 비디오 정보를 사용하여 회의에 참가할 수 있는 환경을 제공한다. 그러나, 기존의 화상회의 시스템은 전용시스템 도입을 필요로 하며, 시스템이 설치된 장소에서만 회의가 가능하므로 특정 플랫폼과 네트워크 환경에 사용자가 종속되는 문제점을 가지고 있다. 또한, 사용자들이 회의 참가자들의 네트워크 접속상황을 사전에 인지해야 하며, 반드시 동일한 종류의 회의 시스템 응용프로그램을 사용해야 하는 약점이 있다. 본 논문에서는 위와 같은 문제점을 해결하기 위해 웹 기반에서 운영되는 화상회의 시스템의 설계와 구현 방법에 관하여 논한다. 제안된 화상회의 회의 시스템은 회의시스템 응용이 서버에서 전송되어 웹 브라우저에서 수행되므로, 회의 참가자들은 웹 브라우저만으로 회의를 수행 할 수 있다. 회의 세션관리 및 회의 응용 도구, 멀티미디어 제어 및 전송도구는 웹 서버에서 전담하므로, 웹 서비스가 가능한 곳에서는 네트워크 접속 상황에 관계없이 화상회의가 가능하다. 웹 기반의 회의 시스템을 구현하는데 가장 중요한 과제인 회의 참가자간의 상호 작용과 지속적인 회의 세션 연결을 구현하기 위해 자바 기술을 사용하였으며, 오디오 및 비디오 제어 및 처리는 하드웨어 제어가 용이한 ActiveX 기술을 사용하였다. A video conferencing system provides sharing the conference environment for geographically dispersed computer users who use the audio and video information. But the conventional video conferencing systems have some problems which are dependent on specific software and/or hardware and bound the certain platform and network environment. Furthermore the participants must know the information about other participants before joining the conference session and they have to use the same video conferencing system. This paper describes design and implementation of the video conferencing system on the WWW to solve the mentioned problems. The conference applications are transmitted from a WWW server and executed in the participants Web browsers. The participant can carry out conference services by using only the web browser. The WWW server takes charge of conferencing management including the information related to the participants and provides supported conference tools such as whiteboard, chatting and multimedia controls. Therefore the participants can easily join the conference sessions and perform conference working regardless of network connection situations. We used the Java to implement the seamless session connections and interaction between the conference participants which are the most important when implementing the video conferencing system on the WWW and used the ActiveX technology about the audio and video controls to make it easy the hardware control.

The purpose of this case study is to present a case of oculolmotor nerve palsy due to midbrain infarction improved by acupuncture and herb medicine. Oculomotor nerve palsy is a disorder associated with dysfunction in the third cranial nerve, which causes eye movement disorder, diplopia and ptosis. The patient, who was diagnosed with Benedikt's Syndrome(Red Nucleus Syndrome), was given oriental medical treatment. Benetikt's Syndrome has the various symptoms of weakness on one side(contralateral) and eye movement disorder, ptosis, diplopia(ipsilateral) etc., but research on Benetikt's Syndrome or midbrain infarction is scant. Results of this study suggest a role for conservative therapy with herb medicine and acupuncture to treat oculomotor nerve palsy(eye movement disorder, ptosis, diplopia, etc., ipsilateral) and right motor weakness(contralateral) due to midbrain infarction. Further research into oriental medical treatment for such disorders will be forthcoming.

김성진,Kim Sung-jin 한국정보통신학회 2005 한국정보통신학회논문지 Vol.9 No.6

FOG(fiber optic gyroscope :광섬유 자이로스코프)는 소형 경량화, 신속한 가동, 저 전력 소모 및 저렴한 가격으로 실현 가능하므로 자이로콤파스시스템에서의 선호도가 높아지고 있다. 본 논문에서는 FOG를 기반으로 하며, 자이로콤파스시스템에 적용할 수 있는 디지털 진북추종 방식을 제안한다. FOG의 earth signal의 해석모델을 분석하고, lock-in증폭기를 통과한 earth signal을 모델링 한다. 두 개의 lock-in증폭기 출력신호를 이용한 진북추종 알고리즘을 개발하고, 이 알고리즘에 의한 디지털 진북추종 방식을 제안한다. 제안한 방식의 성능을 증명하기 위해 컴퓨터시뮬레이션 결과를 포함한다. In the gyrocompass system, the use of the fiber optic gyroscope(FOG) makes this traditional system considerably attractive because it has strong points in terms of weight, power, warming-up time, and cost. In this paper, a novel digital north-finding method based upon an FOG, which can be applied to the gyrocompass system, is proposed. The analytical model for the earth signal of the FOG is described, and the earth signals passed through lock-in amplifiers are modeled. Additionally, a north-finding algorithm using two lock-in amplifier outputs is developed, and the proposed method is organized by the developed algorithm. Simulation results are included to verify the performance of the proposed method.

김성진,김현희,윤성민,이민철,Kim, Sung Jin,Kim, Hyun Hee,Yoon, Sung Min,Lee, Min Cheol 제어로봇시스템학회 2015 제어·로봇·시스템학회 논문지 Vol.21 No.8

In the conventional hot rolling process, the defects of products such as scratches occur due to impact and friction. Impact occurs as a result of the contact of between rollers and the slab. Also, friction occurs in the rolling process. To improve these defects, a variety of processes were developed. The flying touch method is also one of the processes to reduce defects and uses a movable upper roller. To use this unfixed roller, the impact and frictions between rollers and the slab should be minimized. This paper proposes a hot rolling process simulator to verify and test the efficiency of the flying touch method. The simulator was designed to verify the method. This paper also proposes a new impact reducing method and velocity synchronization method which are simulated to realize the method.

측복부 통증은 신, 상부 요로계 질환의 대표적인 척도로 여겨지나 드물게 골반울혈증후군도 감별해야 한다. 골반울혈증후군은 가임기 경산부 여성에서 호발하나 소아청소년기에 원인이 불명확한 측복부 통증을 호소할 때 고려해야 할 질환이다. 저자들은 청소년기 여아에서 만성적인 좌측측복부 통증으로 진단된 골반울혈증후군 1례를 경험하였기에 보고하는 바이다. Flank Pain is a leading indicator of renal and upper urinary tract disease or trauma, and rarely results from pelvic congestion syndrome. Although pelvic congestion syndrome occurs commonly in multi-parous women, pelvic congestion syndrome should also be considered as the cause of flank pain in an adolescent girl. We report the first case of pelvic congestion syndrome presenting with chronic left flank pain in an adolescent girl.
