워즈워스와 예이츠의 역사 경험의 양가성 : 프랑스혁명과 부활절봉기

지승욱 한국예이츠학회 2018 한국예이츠 저널 Vol.56 No.-

워즈워스와 예이츠는 프랑스혁명과 부활절봉기를 겪으면서 각각 새로운 공화국의 설립과 아일랜드의 독립을 꿈꾼다. 하지만 이들 역사적 사건이 불러온 폭력 과 유혈사태는 두 시인이 이전에 가졌던 시각을 변화시킨다. 이들은 양가적 감정에 사 로잡혀 본인의 판단에 대해 끊임없이 의문을 제기하면서 분열된 자아의 양상을 보인 다. 워즈워스와 예이츠는 혼란스러운 역사적 사건을 마주할 수 있는 유일한 방법으로 각각 자연과 언어로 회귀하지만 양가적 감정을 완전히 해소하지 못한다. 두 시인은 프 랑스혁명과 부활절봉기의 빛과 그림자 사이를 끊임없이 오가며 환희와 슬픔, 긍정과 부정, 희망과 두려움을 동시에 시로 표현한다. Both Wordsworth and Yeats dream of the establishment of a new republic and the independence of Ireland, undergoing the French Revolution and the Easter Rising. The violence and bloodshed, which these historical events bring about, however, change the two poets’s mind. They come to have ambivalent feelings, constantly questioning their own judgment of the terrible historical events. Wordsworth and Yeats could face confusing historical events only in nature and language, not completely eliminating their ambivalence in the events, though. The two poets constantly travel between the light and shadow of the French Revolution and the Easter Rising, expressing joy and sorrow, affirmation and denial, hope and fear.

트래킹에 의한 전기화재 가능성 예측

지승욱 한국화재소방학회 2015 한국화재소방학회논문지 Vol.29 No.2

Tracking, which is one of main reasons of the electric fire, progresses gradually, and therefore, the possibility of firecaused by tracking can be predicted by analyzing the stage of its progress. This paper is conducted in order to predict possibilityof the electric fire caused by the tracking in the simulated electric equipment with load. Non-inductive resistance isused as the load. The tracking is happened in a Polyvinyl-chloride-sheathed flat cord, which is a part of the simulatedelectric equipment by means of dropping of electrolyte droplet. In order to predict the possibility of electric fire caused bytracking, we detect the whole current waveforms of the simulated electric equipment. The time-energy analysis and probabilitydistribution are used for analysis of the tracking progress from the whole current waveforms. In accordance with theresults is used for input date of Neural networks, the neural networks can be predict possibility of the electric fire in theelectric equipment by 4 stages. 전기화재의 주요 원인 중 하나인 트래킹은 서서히 진전하는 특징을 가지기 때문에 진전단계를 분석함으로서 화재가능성을 예측할 수 있다. 본 논문은 부하가 연결된 모의 전기설비에서 트래킹에 의한 전기화재 가능성을 예측하고자 시도하였다. 부하는 무유도 저항을 사용하였고, 트래킹은 모의 전기설비의 일부인 비닐캡타이어 타원형코드에 전해액을 적하하여 발생시켰다. 트래킹에 의한 전기화재 가능성을 예측하기 위해 모의 전기설비의 전체 전류파형을 검출하였다. 전류파형으로부터 트래킹 진전을 분석하기 위해 시간-에너지 변환과 확률분포를 이용하였고, 이를 신경망에 입력함으로써 전기설비 내에서 전기화재의 발생가능성을 4단계로 예측할 수 있게 하였다.

초기 시로 바라본 예이츠의 민족주의

지승욱 한국예이츠학회 2016 한국예이츠 저널 Vol.50 No.-

프로테스탄트 혈통의 한계를 가지고 있었던 예이츠는 아일랜드 내에서 불분명한 자신의 위치를 확고히 하고자 문학적 완성이라는 대의를 표명한다. 그는 문학완성이야말로 민족의 정체성을 재구축 시키고 새로운 아일랜드 건설을 할 수 있다고 믿었다. 민족의 뿌리에서부터 정신적․문화적 회복해야 한다는 그의 신념은 그의 초기작품에 자주 등장하는 신화, 민담, 전설을 통해 표명한다. 하지만 그는 게일어가 아닌 영어를 사용하면서 아일랜드 민족주의자 대열에 동화 되지 못하는 모습을 드러낸다. 결국 그는 내면적으로 양자택일할 수 없는 불분명한 모습을 영국과 아일랜드에 사이에서 유감없이 드러낸다. Yeats resists against the spreading of British culture in Irish culture, but he continually attempts to integrate cultures by writing about issues such as religion, race, and language in his works. Hidden in the gorgeous appearance of his works, the problems of national cause, languages, and the sense of distance from nationalists lurk here and there. In the larger frame of Irish nationalism, Yeats’s single ideology of cultural nationalism operates in a limited range. In other words, a sense of distance occurs between the goal the Irish nationalists aim at and the goal Yeats pursues. The fact is that internal conflicts took place in Ireland.

트래킹 검출을 위한 주파수-시간 분석(분할-FFT)

지승욱,이상훈,김충년,이춘하,이광식 대한전기학회 2004 전기학회논문지C Vol.53 No.10-C

A electromagnetic waves are used for sensing in insulation diagnosis at electric machine or equipment. When it a method, waves are transformed into the FFT(Fast Fourier Transform); a kind of the process for data transformation. In a general way, a scientist use frequncy band 30[㎒]~1[㎓] to applied field. If we are measured high frequency band, we will need to a high capacity hardware. Also a antenna has a fault on atmospheric phenomena, outside environment and the like. In this paper We proposed new method for detecting electric equipment faulty state using only electric voltage which is generally measured in the electric and electronic field. It is called the Patition-FFT The analytic method is this first divide measured voltage waves into equal parts, second each deal with give effect to the FFT, finally each results deal with a graphic method and gather graphic. We are compare Partition-FFT with discharge form by tracking tester. As the result it demonstrated that the Partition-FFT is applicable.

Functional Role of a Conserved Sequence Motif in the Oxygen-dependent Degradation Domain of Hypoxia-inducible Factor 1α in the Recognition of p53

지승욱 한국유전체학회 2008 Genomics & informatics Vol.6 No.2

Hypoxia-inducible factor 1α (HIF1α) is a transcription factor that plays a key role in the adaptation of cells to low oxygen stress and oxygen homeostasis. The oxygen- dependent degradation (ODD) domain of HIF1α is responsible for the negative regulation of HIF1α in normoxia. The interactions of the HIF1α ODD domain with partner proteins such as von Hippel-Lindau tumor suppressor (pVHL) and p53 are mediated by two sequence motifs, the N- and C-terminal ODD (NODD and CODD). Multiple sequence alignment with HIF1α homologs from human, monkey, pig, rat, mouse, chicken, frog, and zebrafish has demonstrated that the NODD and CODD motifs have noticeably high conservation of the primary sequence across different species and isoforms. In this study, we carried out molecular dynamics simulation of the structure of the HIF1α CODD motif in complex with the p53 DNA-binding domain (DBD). The structure reveals specific functional roles of highly conserved residues in the CODD sequence motif of HIF1α for the recognition of p53.

NMR Characterization of Oxidized Form of Human 8-kDa Dynein Light Chain

지승욱,신재선,정우진 한국자기공명학회 2010 Journal of the Korean Magnetic Resonance Society Vol.14 No.2

Redox-dependent conformational change of human 8-kDa Dynein light chain (LC8) plays important role in regulating NF-κB signaling pathway. In this study we characterized the structural states of the oxidized and reduced forms of LC8 by using NMR spectroscopy. The 1H-15N 2D HSQC spectra of oxidized LC8 indicated that no significant change in tertiary structure of LC8 occurred upon oxidation. The chemical shift perturbations of LC8 upon oxidation suggest a redox-dependent quaternary structural change.

The Discharge Mechanism Leading to the Tracking Progress in Polyvinyl-Chloride-Sheathed Flat Cord

지승욱,임동영,배성우,최영길 대한전기학회 2019 Journal of Electrical Engineering & Technology Vol.14 No.1

This paper suggests the mechanism of the discharge phenomenon that leads to tracking progress. For this purpose, a polyvinyl-chloride-sheathed flat cord (PVCSFC), which is widely used as a distribution cord, was employed and an artificial crack was intentionally made on the surface. Tracking was progressed using electrolyte droplets. The mechanism of the discharge phenomenon was suggested from the measurement and analysis of the current waveform. As carbonization progressed during the tracking progress, the frequency of scintillation discharge also significantly increased. The mechanism for scintillation discharge during the tracking progress was based on the change in the electric field of the dry band, initial electron, electron avalanche, photoionization, secondary electron generation (electron detachment, photoemission, and secondary electron emission avalanche), space charge due to positive ions, and formation of conductive channels. This discharge mechanism could explain the physical phenomenon and change in the current waveform that occurs during the tracking progress.

- Most of electric accidents are happened in the place where activities are frequent by common people who has low electric knowledge. Also, accidents are increased in the low voltage electric equipment. So, it is increased to spread the dispersion or non-utility power generation system. It means that ordinary times observation is required for electric equipments by common people. This paper is studied for the diagnosis method of electric equipment that common people can diagnose easily. Voltage is generally and exactly measured in the electric and electronic field. We suggest new analysis tools using only electric voltage. It is called the Time-Energy analysis.The Time-Energy analysis is as followingFirst, divide measured voltage waves into same parts,Second, conducted FFT(Fast Fourier Transform) transform for each divided period,Finally, each results are reassembled after graphic treatment.We compared Time-Energy analysis with discharge form by tracking tester. As the result, tracking discharge processes distinguished clearly.
