‘해방’의 전통과 복원 - 김학철을 중심으로

김민수 ( Kim¸ Min-su ) 한국문학언어학회 2021 어문론총 Vol.89 No.-

이 글은 조선의용군 출신 작가 김학철(金學鐵, 1916~2001)의 서지를 보완하기 위하여 작성된 것이다. 일차적으로는 김학철이 독립운동가에서 작가로 변모했던 해방 직후의 불완전한 서지를 갈무리하고자 하였다. 월북 이전의 작품목록을 정리하는 과정을 통해 당시의 정치지형을 검토할 수 있게 되었다. 더 나아가 김학철이 조선의용군을 형상화한 작품이 ‘해금’을 전후한 시기에 어떠한 방식으로 복원된 것인지 살피고자 하였다. 1980년대 민주화의 열기와 맞물려 ‘해방전후사(解放前後史)’는 출판문화계의 지대한 화두로 자리했다. 특히 중국에서 출판된 김학철의 전기문학 『항전별곡』(1983)과 『격정시대』(1986) 등이 일본을 경유하는 방식으로 한국에서 해적판으로 출판된 정황을 추적하고자 하였다. 이때 그의 소설은 민족해방운동에 관한 ‘사료’로 취급된 바 있을 정도이다. 이처럼 규율화된 폭력(Gewalt)을 무릅쓰고 우리에게 돌아온 조선의용군 서사는 ‘잔존(Survivance)’의 가치를 논의하기에 충분한 것이라 할 수가 있다. ‘해방’과 ‘해금’ 사이의 공차를 저울질하는 작업을 통하여 반세기에 걸쳐 금압의 역사로 자리했던 ‘해방공간’의 의미를 재구할 수 있을 것이라 기대한다. This article attempts to fill out the bibliography of Kim Hak-cheol (1916-2001), author and member of the Korean Volunteer Army. First, I organize incomplete bibliographic information from the period following the Liberation, when Kim shifted from independence movement activist to author. In organizing Kim’s list of works prior to his defection to North Korea, I also investigate the political geography of the period. I then examine how Kim’s depiction of the Korean Volunteer Army was restored around the time of the ‘lifting of the ban.’ In step with the fervor of democratization in the 1980s, ‘history at the time of liberation’ became an immensely important topic in the publishing world. In particular, I trace the circumstances under which Kim’s biographical works Hangjeonbyeolgok (1983) and Gyukjeongsidae (1986), originally published in China, were published in pirate editions by way of Japan. At this time, Kim’s novels were treated mostly as historical resources on the national liberation movement. Overcoming disciplinary violence (gewalt) to return to South Korean readers, this Korean Volunteer Army narrative offers an important chance to discuss the value of ‘survivance.’ By measuring the difference that appears between the ‘liberation’ and the ‘lifting of the ban,’ it is possible to begin reconstructing the meaning of the ‘Liberation Period,’ which occupied the position of suppressed history for half a century.

보수적 회계처리와 중립적 회계처리가 가치평가오류에 미치는 영향 : 보수적 회계처리 vs 중립적 회계처리

김민수(Kim, Min-Su),이명건(Lee, Myung-Gun) 한국회계정보학회 2021 재무와회계정보저널 Vol.21 No.1

[Purpose] Conservatism in accounting information means recognizing negative information early, and recognizing positive information slowly after satisfying the vesting condition. On the other hand, neutral accounting information means that there is no discrimination between negative and positive information. The aim of this study is to analyze the effects of such conservative and neutral accounting information on valuation errors. [Methodology] This study analyzed companies listed on the KOSPI from 2001 to 2015. The measure of conservatism followed Khan and Watts(2009), and the measure of neutralism was used by taking the absolute value of the measure of conservatism and multiplying it by a negative number. To measure the valuation error, the model suggested in the study of Rhodes-Kropf et al.(2005) was used. [Findings] As a test result, as the tendency of conservatism increases, valuation errors increase, which means that accounting informaiton biased toward negative information is negative in terms of valuation accuracy. On the other hand, the more neutral accounting information is, the less valuation errors are, and it can be interpreted that reporting positive and negative information in a balanced way has a positive effect on the accuracy of valuation. [Implications] In general, conservatism in accounting is considered to reduce investment risk by providing negative information to investors early, but the results of this study show that a report focused on negative information may rather distort the economic situation of a company. [연구목적] 회계정보의 보수주의란 부정적 정보는 조기에 인식하고, 긍정적인 정보는 가득 조건을 만족한 후에 천천히 인식하는 것을 의미한다. 한편 중립적 회계정보는 부정적인 정보와 긍정적인 정보의 인식 시기에 차별을 두지 않는 것을 말하며, 이와 같은 보수적 회계처리와 중립적 회계처리가 가치평가오류에 미치는 영향을 분석한 것이 본 연구의 목표이다. [연구방법] 본 연구는 2001년~2015년 기간에 유가증권시장에 상장된 기업을 대상으로 분석하였다. 보수주의 측정치는 Khan and Watts(2009)를 따랐으며, 중립주의 측정치는 보수주의 측정치에 절대값을 취한 후 음수를 곱하여 활용하였다. 가치평가 오류 측정치는 Rhodes-Kropf et al.(2005) 연구에서 제시된 모델을 사용하였다. [연구결과] 검증결과 보수주의 성향이 증가할수록 가치평가오류가 증가하는 것으로 나타났으며 이는 부정적 정보에 편향된 회계처리가 가치평가 정확도 측면에서 는 부정적임을 의미한다. 반면 중립적인 회계처리를 할수록 가치평가오류는 감소는 하는 것으로 나타났으며 긍정적 정보와 부정적 정보를 균형 있게 보고하는 것이 가치평가의 정확도에 긍정적으로 영향을 미치는 것으로 해석할 수 있다. [연구의 시사점] 일반적으로 보수주의 회계처리가 부정적 정보를 조기에 투자자들에게 제공함으로써 투자위험을 줄이는 것으로 간주되나, 본 연구의 결과는 부정적 정보에 치중한 보고가 오히려 기업의 경제적 실상을 왜곡하여 보고할 가능성이 있음을 시사하였다.

케이블 구조시스템의 경우 자기 평형 상태를 유지하기 때문에 장력이 손실된 특정 케이블을 재긴장을 하지 않으면 구조엔지니어가 요구한 하중보다 더 큰 하중이 다른 케이블에 전달되어 손상을 야기 할 수 있다. 또한, 턴버클을 이용한 재긴장 방법이 기존에 널리 적용되고 있지만 정확한 장력조절과 대구경 케이블에는 적절하지 못하고 인장재의 하중의 크기를 측정하는 것이 어렵다. 따라서 효과적으로 재긴장 할 수 있는 유압식 볼팅 접합부를 개발하고 인장력을 실시간으로 확인할 수 있는 모니터링 시스템을 적용하였다. 본 논문에서는 개발된 시스템의 현장 적용성 실험과 결과를 제시하였다. Due to the self-equilibrium status of the cable system, the loss of the tensioning in the cable system results in other cables carrying larger tension forces than those initially calculated by structural engineers. Also, turn-buckle systems, which have been widely used to pre-tension and/or re-tension the cables, are limited to use for small cables and to provide a rough estimation for tension forces. In this study, the re-tensioning cable connection systems were developed to overcome the problems mentioned above. The main objective of the proposed system is to re-tension large cables and measure the exact amount of tension forces of the cable systems. This connection system is also combined with the wireless signal monitoring module so that engineers are able to measure the tension forces any place where the internet is available. This paper presents the development of the re-tensioning cable connection systems and experiment using the real-scale cable systems to verify the fe-tensioning and signal monitoring systems.

Electrical Properties of Mg-Doped AlxGa1-xAs Epitaxial Layers Grown by Using Molecular Beam Epitaxy

김민수,Do Yeob Kim,Tae Hoon Kim,김건식,Hyun Young Choi,Min Young Cho,Su Min Jeon,H. H. Ryu,W. W. Park,김종수,김진수,D. Y. Lee,손정식,J. Y. Leem 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.2

Magnesium (Mg)-doped AlxGa1-xAs epitaxial layers were grown by using molecular beam epitaxy (MBE) on (100) GaAs substrates under different growth conditions, such as Mg cell temperature, Al mole fraction, substrate temperature and As/Ga beam equivalent pressure (BEP) ratio. The epitaxially-grown Mg-doped AlxGa1-xAs layers were characterized using Hall measurements to investigate their electrical properties. The carrier concentration of the Al0:13Ga0:87As layers decreased from 1.86 × 1017 × 4.87 × 1014 cm-3 when the substrate temperature was increased. This variance in carrier concentration is attributed to a dramatic decrease in Mg concentration in the III-V epilayers with increasing substrate temperature. The mobility and the carrier concentration of the Mg-doped AlxGa1-xAs layers also depended on the Al mole fraction and As/Ga BEP ratio. Finally, the Hilsum estimates were found to be in good agreement with the experimental points in the extrapolated curve.

Cotton and silk fabrics were dyed with Schizandra chinensis fruit extract using the optimized extraction and dyeing conditions in order to impart functional properties such as deodorization and antimicrobial activity to the fabrics. The extracts were easily obtained from the dried Schizandra chinensis fruits by treating them with pure ethanol at $80^{\circ}C$ for 60 min. When dyed at $130^{\circ}C$ for 60 min under pH 3 with a 10% aqueous ethanol solution that contains the extract and salt concentrations of 5.5% and 20% owf, silk fabrics could be dyed to obtain a color depth (K/S) of 14.2. Cottons were dyed to a K/S of 13.4 under the same dyeing conditions except for a pH of 9. The poor color-fast properties of the dyed fabrics were improved by a combined treatment of citric acid crosslinking and post-mordanting with aluminum alum. Moreover, the dyed silk and cotton fabrics showed excellent ammonia deodorization performance and antimicrobial activity against both Staphylococcus aureus and Klebsiella pneumoniae.

상황버섯 균사체 추출물의 숙취해소 효과에 관한 연구

This study was conducted to evaluate the hangover relieving effect of Sanghwang mushroom mycelium extract (SME). The extract showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging effect in a concentration-dependent manner and high antioxidant capacity ($56.67{\pm}1.77%$) when administered at $120{\mu}g/mL$. In addition, SME significantly increased (p < 0.005) the aldehyde dehydronase (ALDH) activity ($126.03{\pm}9.11%$) when applied at 8 or $16{\mu}L/mL$. A locomotor activity test showed that the alcohol-water treated group showed significantly decreased motor activity at 90 min post-administration. However, the alcohol-SME treated group showed a 20-fold higher motor activity than that observed in the alcohol-water treated group at 90 min post-administration. Blood was harvested from each mouse at 90 min post-administration, and both alcohol and aldehyde concentrations were measured. The alcohol-SME treated group showed significantly lower (p < 0.5) alcohol ($120.13{\pm}12.83{\mu}g/mL$) and aldehyde ($7.26{\pm}1.22{\mu}g/mL$) concentrations than the values observed in the alcohol-water treated group. These results suggest that the hangover relieving effect of SME results from increased ALDH activity, which reduces the aldehyde concentration in the blood.

As the fabrication technology used in FPDs(flat-panel displays) advances, the size of these panels is increasing and the pattern size is decreasing to the um range. Accordingly, a cleaning process during the FPD fabrication process is becoming more important to prevent yield reductions. The purpose of this study is to develop a FPD cleaning system and a cleaning process using a two-phase flow. The FPD cleaning system consists of two parts, one being a cleaning part which includes a two-phase flow nozzle, and the other being a drying part which includes an air-knife and a halogen lamp. To evaluate the particle removal efficiency by means of two-phase flow cleaning, silica particles $1.5{\mu}m$ in size were contaminated onto a six-inch silicon wafer and a four-inch glass wafer. We conducted cleaning processes under various conditions, i.e., DI water and nitrogen gas at different pressures, using a two-phase-flow nozzle with a gap distance between the nozzle and the substrate. The drying efficiency was also tested using the air-knife with a change in the gap distance between the air-knife and the substrate to remove the DI water which remained on the substrate after the two-phase-flow cleaning process. We obtained high efficiency in terms of particle removal as well as good drying efficiency through the optimized conditions of the two-phase-flow cleaning and air-knife processes.

ZnO nano-fibrous thin films with various precursor concentrations ranging from 0.2 to 1.0 mol (M) were grown by spin-coating method and effects of the precursor concentration on surface and optical properties of the ZnO nano-ribrous thin films were investigated by using scanning electron microscopy (SEM) and photoluminescence (PL). ZnO nuclei were formed at the precursor concentration below 0.4 M and the ZnO nano-fibrous thin films were grown at the precursor concentration above 0.6 M. Further increase in the precursor concentration, the thickness of the ZnO nano-fibrous thin films is gradually increased. The intensity and the full-width at half-maximum (FWHM) of the near-band-edge emission (NBE) is increased as the precursor concentration is increased. The deep-level emission (DLE) is red-shifted as the precursor concentration is increased. 스핀코팅 방법을 이용하여 다양한 농도의 전구체로 ZnO 나노 섬유질 박막(ZnO nano-fibrous thin films)을 성장하였고, 그에 따른 표면 및 광학적 특성 변화를 scanning electron microscopy (SEM)와 photoluminescence (PL)을 이용하여 측정하였다. 전구체 농도가 0.4 mol (M) 이하 일 때는 성장률이 낮아 ZnO 핵생성만이 되었고, 0.6 M 이상일 때 ZnO 박막은 나노섬유질 구조가 되었다. 전구체 농도가 더욱 증가함에 따라 ZnO 나노 섬유질의 굵기가 굵어졌고 ZnO 박막의 두께도 단계적으로 두꺼워졌다. 전구체 농도가 증가함에 따라 ZnO 나노 섬유질 박막의 photoluminescence (PL)의 근밴드가장자리 광방출(near-band-edge emission) 피크 세기와 full-width at half-maximu (FWHM)이 증가하였고, 깊은 준위 광방출(deep-level mission) 피크는 적색편이(red-shift)하였다.

Adhesive bonding is one of the most promising joining methods which may substitute for conventional metallurgical joining processes, such as welding, brazing and soldering. Curing behavior and mechanical properties of adhesive joint are largely dependent on the curing agent including hardener and catalyst. In this study, effects of curing system on the curing behavior and single-lap shear strength of epoxy adhesive joint are investigated. Dihydrazide, anhydride and dicyandiamide(DICY) were chosen as hardener and imidazole and triphenylphosphine(TPP) were chosen as catalyst. In curing behavior, TPP showed the delay of the curing rate for DICY and ADH at $160^{\circ}C$, compared to imidazole catalyst due to the high curing onset/peak temperature. DICY seemed to be most beneficial in the joint strength for both steel and Al adherends, although the type of adherends affected the shear strength of epoxy adhesive joint.

가상 트랜잭션을 이용한 시계열 데이터의 데이터 마이닝

대용량의 데이터들로부터 사용자가 인하는 데이터를 찾기 위하여 많은 데이터 마이닝 기술들이 연구되어 실제 응용프로그램에서 많이 적용되고 있다. 이러한 데이터 마이닝 기술들은 시계열 데이터를 이용하는 경우보다 트랜잭션 데이터를 이용하여 유용한 정보를 찾는 경우에 초점이 맞춰져 있다. 본 논문에서는 시계열 데이터를 트랜잭션 데이터로 변환하는 접근방법을 소개한다. 가상 트랜잭션은 서로 상대적으로 근접한 시간에 발생하는 이벤트의 집합이라고 정의하며, 가상 트랜잭션 생성기는 가상 트랜잭션을 생성시 시간윈도우와 이벤트 윈도우 방법을 사용한다. 본 논문의 접근 방법을 사용하여 기존의 트랜잭션 데이터를 이용하는 많은 데이터 마이닝 알고리즘들을 수정 없이 시계열 데이터에 적용하여 유용한 정보를 찾을 수 있다. There has been much research on data mining techniques for applying more advanced applications. However, most of those techniques has focused on transaction data rather than time series data. In this paper, we introduce a approach to convert time series data into virtual transaction data for more useful data mining applications. A virtual transaction is defined to be a collection of events that occur relatively close to each other. A virtual transaction generator uses time window or event window methods. Our approach based on time series data can be used with most conventional transaction algorithms without further modification.
