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.

청각장애인을 위한 음성인식 기반 메시지 전송 시스템

김성진,조경우,오창헌,Kim, Sung-jin,Cho, Kyoung-woo,Oh, Chang-heon 한국정보통신학회 2018 한국정보통신학회논문지 Vol.22 No.12

음성인식 서비스는 청각장애인에게 화자의 음성을 텍스트로 변환하여 시각화함으로써 의사소통의 보조적인 수단으로 사용되고 있다. 하지만 강의실 및 회의실과 같은 개방된 환경에서는 다수의 청각장애인에게 음성인식 서비스를 제공하기 힘들다. 이를 위해 주변 환경에 따라 음성 인식 서비스를 효율적으로 제공하기 위한 방법이 필요하다. 본 논문에서는 화자의 음성을 인식하여 변환된 텍스트를 다수의 청각장애인에게 메시지로 전달하는 시스템을 제안한다. 제안하는 시스템은 다수의 사용자에게 동시에 메시지를 전달하기 위해 MQTT 프로토콜을 사용한다. MQTT 프로토콜의 QoS level 설정에 따른 제안 시스템의 서비스 지연을 확인하기 위해 종단 간 지연을 측정하였다. 측정 결과 가장 신뢰성이 높은 QoS level 2와 0간의 지연이 111ms로 대화 인식에 큰 영향을 끼치지 않음을 확인하였다. The speech recognition service is used as an ancillary means of communication by converting and visualizing the speaker's voice into text to the hearing impaired persons. However, in open environments such as classrooms and conference rooms it is difficult to provide speech recognition service to many hearing impaired persons. For this, a method is needed to efficiently provide it according to the surrounding environment. In this paper, we propose a system that recognizes the speaker's voice and transmits the converted text to many hearing impaired persons as messages. The proposed system uses the MQTT protocol to deliver messages to many users at the same time. The end-to-end delay was measured to confirm the service delay of the proposed system according to the QoS level setting of the MQTT protocol. As a result of the measurement, the delay between the most reliable Qos level 2 and 0 is 111ms, confirming that it does not have a great influence on conversation recognition.

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.

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.

癸未使行時의 南玉과 那波師曾

김성진(Kim Sung-Jin) 한국문학회 2005 韓國文學論叢 Vol.40 No.-

This essay is to review the companionship between Nam-Ok(南玉), a literary man in Chosun Dynasty who was dispatched as 'an envoy to Japan in the year of Gyemi'(癸未) and Napa-Sajeung(那波師曾) who was a literary man in Japan. Their companionship was so close as to arose followers' interest. I think this fact is of great help in investigating how our literary trend was in those days. This essay is mainly to review Nam-Ok's literary world. The study on Nam-Ok had not almost been tried yet though he was a member of governmental servant of composing literary works who was chosen as the best writer in that period. However, his remaining works were 'writings on envoy travels'(使行錄), recordings of 'conversation through writing only'(筆談), so the change of his literary world was difficult to analyze. From this point, I pay attention to his records of 'conversation through writing only' with Japanese writers, by focusing on that this fact may reflect lots of opinions and interests in both countries' literary world and situations. Nam-ok gave a favorable comment on Napa-Sajeung to recognize him as the best writer in Japanese literary world. So this essay tries to clarify the root of their similarity. The main issue of the above is that Nam-Ok held Jungju-Hak(程朱學)-centered view of the world, like Sung-DaeJung(成大中), Won-JungGeo(元重擧), criticizing the literature of Lee-BanRyong(李攀龍), Wang-SaeJung(王世貞) whose literary influence were overwhelming throughout the country. This essay examines the conflict between Korea and Japan, broken out due to Jorae-Hak(徂徠學) that had spoken against Jungju-Hak(程朱學). In those days of the 'envoy travel in the year of Gyemi', Chosun's literary world was mainly at the time of paesa(稗史) and sopum(小品) influenced by 'Gongan party'(公安派) and 'Gyungryung party'(竟陵派). Nevertheless, Nam-Ok and Napa-Sajeung didn't express their interests in them. This fact means Nam-Ok(南玉) devoted himself to Selected Poems of Gumnam(劍南詩抄), thus not paying attention to 'the literature of the end of Ming and the beginning of Ching dynasty'(明末淸初文學) which were overwhelming throughout the country. Napa-Sajeung also did not pay attention to the Japanese intellectual society exclusively occupied by Jorae-Hak. In conclusion, Nam-Ok and Napa-Sajeung stood aside from the mainstream of each country's literary world, so that it seems to be the reason why they were not treated in the study of this field. This essay investigates the before and after situation, by focusing on their 'conversation through writing only and their give-and-take of literary works'.(筆談唱和)

잡음재밍 효과에 대한 정량적 분석 기법

김성진,강종진,Kim, Sung-Jin,Kang, Jong-Jin 한국군사과학기술학회 2005 한국군사과학기술학회지 Vol.8 No.4

In this paper, a technique for the quantitative analysis of the noise jamming effect is proposed. This technique based upon the mathematical modeling for noise jammers and the probability theory for random processes analyses the jamming effect by means of the modeling of the relationship among jammer, radar variables and radar detection probability under noise jamming environment. Computer simulation results show that the proposed technique not only makes the quantitative analysis of the jamming effect possible, but also provides the basis for quantitative analysis of the electronic warfare environment.

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.

김성진,윤선민,김성규,Kim, Sung-Jin,Youn, Seon-Min,Kim, Sung Kyu 한국의학물리학회 2013 의학물리 Vol.24 No.4

양측성 유방암 환자를 대상으로 부피적 조절회전방사선치료와 세기조절방사선치료의 선량학적 결과를 비교하여 효율적인 치료방법을 제시함을 목적으로 한다. 5명의 환자를 대상으로 8개 빔의 세기조절방사선치료와 12개 빔의 세기조절방사선치료, 1회전 부피적 조절회전방사선치료 계획을 수립하였다. 그 결과를 DVH 분석을 통해 선량학적으로 비교분석하였다. PTV의 평균선량과 $D_{98}$을 보면 12-IMRT가 $51.04{\pm}0.57$ Gy (오른쪽), $50.80{\pm}1.07$ Gy (왼쪽), $42.94{\pm}16.16$ Gy (오른쪽), $42.56{\pm}2.09$ Gy (왼쪽)로 우수한 경향을 보인다. HI와 $CI_{90,95}$에서도 12-IMRT가 우수한 결과를 보였다. 중요장기에서는 세치료계획 모두 우수한 결과를 보였지만 12-IMRT에서 가장 낮은 선량을 보였다. 12-IMRT가 PTV와 OAR의 선량학적측면에서 우수한 결과를 보여주었다. A study was performed comparing dosimetric characteristics of volumetric modulated arc and intensity modulated radiatio therapy on patients with bilateral breast cancer. For 5 patients, 3 plans were made for each patient; IMRT beams 8 and 12 of the beam intensity modulated radiation therapy, volumetric modulated arc therapy plan. The average PTVs volumes and $D_{98}$ for 12-IMRT were $51.04{\pm}0.57$ Gy (right), $50.80{\pm}1.07$ Gy (left), $42.94{\pm}16.16$ Gy (right), $42.56{\pm}2.09$ Gy (left). HI ($D_5{\sim}D_{95}$) and $CI_{90,95}$, even 12-IMRT has shown excellent results. In OAR, 3 plans showed excellent results. But the lowest dose of 12-IMRT. 12-IMRT achieved similar PTV coverage and sparing of organs at risk than 8-IMRT and VMAT.

국내 문헌정보학의 이론 활용 연구 동향 분석 - 2010년-2014년 『한국문헌정보학회지』를 중심으로 -

김성진,Kim, Sung-Jin 한국비블리아학회 2015 한국비블리아학회지 Vol.26 No.4

본 연구는 이론활용 관점에서 국내 문헌정보학 연구의 특성을 조사함으로써 문헌정보학의 학문적 성장과 변화를 파악하고자 하였다. 이를 위해 2010년에서 2014년까지 최근 5년 동안 "한국문헌정보학회지"에 게재된 연구논문 344편에 대한 내용분석을 실시하였다. 그리고 1984년부터 2003년까지 조사된 과거 연구결과와의 비교를 통해 종단 분석을 시도하였다. 분석결과, 13.7%의 논문에서 평균 2.02회 이론을 활용하였다. 단순언급 수준으로 이론이 가장 많이 활용되었고, 그 다음 이론응용 수준으로 활용되었다. 교육과 정보이용/탐색 주제 영역에서의 이론 활용이 가장 활발하였다. 문헌정보학의 고유 이론은 31.9%, 사회과학 이론은 58.3% 활용되었다. 이러한 결과를 과거와 비교하면, 이론활용 연구가 양적으로 크게 증가하지는 않았지만 최근 연구일수록 이론을 깊이 있게 활용하는 양상이 두드러졌기 때문에 이론활용 연구가 질적으로 성장했음을 알 수 있다. 또한 문헌정보학의 고유 이론을 활용하는 비중은 줄고 사회과학 분야, 특히 교육학과 심리학과의 연관성이 강해진 것을 확인할 수 있었다. The purpose of this study is to examine research trends on theory use in Korean LIS, and ultimately to identify its academic growth and change. This study conducted content analysis, with a sample of 344 articles in Journal of the Korean Society for Library and Information Science during the past five years from 2010 to 2014. Then longitudinal analysis was additionally carried out by comparing with a data set from 1984 to 2003. Findings are as follows. 13.7% of research articles used theories on average 2.02 times. The most theories were deployed at the level of Spot Citing and the next most theories were at the level of Theory Application. Research on the subject of education and information use/seeking used theories most frequently. Theories from LIS were 31.9% and those from social science were 58.3% of all. Also, longitudinal analysis results support the conclusion that there was no quantitative increase but was clear qualitative growth in theoretical research of LIS. And the current theoretical framework of LIS research has closer relationships with pedagogy and psychology among social science disciplines than in the past.
