최근에 한국기초과학지원연구원에 설치된 초고전압 투과전자현미경은 원자분해능(점분해능 $1.2{\AA}$ 이하)의 구현과 고경사각 tilting 기능(${\pm}60^{\circ}$)에 의해 시편의 원자배열 구조를 3차원적으로 이미징할 수 있는 고성능 투과전자현미경이다. 이에 더하여 FasTEM이라는 원격 운용 시스템이 갖춰져 있어서 장비의 직접운용에 따른 여러 제약을 극복할 수 있게 한다. 초고전압 투과전자현미경의 원격운용을 위해 FasTEM 원격 시스템은 본원 초고전압 투과전자현미경에 설치된 Server 시스템과 서울분소에 설치된 Client 콘솔 시스템을 155 Mbps급 초고속 선도망 KOREN에 연결하여 구성하였으며 서울분소에서 대전본원의 초고전압 투과전자현미경을 운영하여 Au의 [001] 고분해능 영상을 얻는데 성공하였다. 초고전압 투과전자 현미경의 조사계 및 결상계 시스템 파라메타들의 조정, 각각의 detector 시스템 조정과 이미징, goniometer와 aperture 구동을 위한 motor-driven system들의 동작 등 초고전압 투과전자현미경의 원격 조정은 원격 작업자가 현장에 있는 것과 마찬가지로 실시간 운용이 가능하였다. 초고전압 투과전자현미경과 IT 기반기술의 접목에 의해 실현된 원격운용 기능은 국가적 공동연구시설에 대한 e-Science Grid를 구축하는데 중요한 역할을 하리라 기대된다. The high voltage electron microscope (HVEM) newly installed in KBSI is an advanced transmission electron microscope capable of atomic resolution (${\leq}1.2{\AA}$ point-to-point resolution) together with high titling function (${\pm}60^{\circ}$), which are suitable to do 3-dimensional atomic imaging of a specimen. In addition, the instrument can be controlled by remote operation system, named as 'FasTEM' for the HVEM, which is favorable to overcome some environmental obstacles resulting from the direct operation. The FasTEM remote operation system has been established between the headquarter of KBSI in Daejeon and the Seoul branch. The server system in the headquarter has been connected with a portable client console system in the Seoul branch using an advanced internet resource, 'KOREN' of 155 Mbps grade. Most of the HVEM functions essential to do remote operation are available on the portable client console. The experiment to acquire the high resolution image of [001] Au has been achieved by excellent transmission of control signals and communication with the HVEM. Real-time reaction like direct operation, such as controls of the illumination and projection parameters, acquisition and adjustment of each detector signal, and electrical steering of each motor-driven system has been realized in remote site. It is positively anticipated that the first remote operation of HVEM in conjunction with IT infraengineering plays a important role in constructing the network based e-Science Grid in Korea for national user s facilities.

현대 일본어의 이중부정의문문에 관한 고찰

김영민(Kim, Young-min) 가천대학교 아시아문화연구소 2017 아시아문화연구 Vol.44 No.-

본고에서는 현대 일본어의 이중부정의문문에 초점을 맞추어,「~なくない?」 의 의미와 용법 및 그 독특성을 밝혀내고자 고찰하였다. 선행연구에서는 일부품사에 국한된 표현이며, 젊은 사람들에게만 나타나는 현상으로 간주되어 왔으나, 본 연구의 결과 형용사, 명사, 동사에 걸쳐 골고루 사용된다는 것과 TV의 상품 선전에도 사용되는 것으로 미루어보아 사용 층이 넓어지고 있다는 사실을 알 수 있었다. 본고에서 고찰한 내용은 다음과 같이 정리할 수 있다. 첫째, 이중부정의문문 「~なくない?」의 특성 및 현상에 대해 살펴보았다. 그 결과 부정의문문 「~ない?」가 「~よね」라는 의미를 나타내는 것에 반해 이중부정의문문 「~なくない?」에는「~よね?」와 「~ないよね?」가 존재한다는 것을 인정하고, 「~なくない?」의 문제점으로 지적된 의미해석의 이중성에 대해서도 이론적인 근거를 제시했다. 둘째, 이중적인 기능이 가능한 이유는 부정사 「ない」의 작용역이 어디까지 영향을 미치는가에 달려있다는 것을 제시하였다. 뿐만 아니라 이중부정의문문으로 간주되는 표현 중에는 「つまらなくない?」, 「危なくない?」와 같이 형용사에 내제되어 있지만 부정의 의미를 띠지 않는 「ない」와의 결합으로 인해 긍정적 해석을 가능케 한다는 사실을 밝혀낼 수 있었다. 셋째, 「~なくない?」의 기능 및 용법에 대해 면밀히 고찰하여 이중부정의문문은 단순히 상대에게 새로운 정보를 구하거나 의견을 묻기 보다는 동의요구나 배려표현으로 사용되고 있으며 긍정해석과 부정해석을 가능하게 하는 모호한 표현이라는 특성도 발견할 수 있었다. This dissertation tries to figure out meaning, usage and characteristic of “nakunai” form focused on double negative interrogative sentence of modern Japanese. In preceding researches, “nakunai” have been considered as that used in limited word class and by contemporary young-aged people. As a result of research, however, “nakunai” is used in various word classes like adjective, noun or verb, and also this form became to spread out to broader age group through the fact that this form is used in television commercials. The contents of the dissertation can be listed in three points. First, characteristics and usage of “~nakunai” as double negative interrogative form are observed. When negative interrogative form, “~nai” contains the meaning of “~yone,” double negative interrogative form, “~nakunai” includes “~yone” and “~ naiyone” forms. Based on this observation, the researcher sought logical validity for dualistic understanding of “~nakunai” which is considered as the point of dispute. Second, the role of infinitive “nai” and its scale of usage that makes “nakunai” has dualistic function are observed. Some double negative interrogative forms such as “tumaranakunai” or “abunakunai” which connote negative meaning in its adjective but do not denote negative meaning, are able to be understood in positive meaning by being connected with “nai.” Third, through substantial consideration of function and usage of “~nakunai,” the researcher observed this following fact: double negative interrogative form is ambiguous expression that allows people dualistic understanding, positive and negative, and also means care for others or asking agreement, rather simply asking new information or one’s opinion.

중국 후기 제국 시기 지배 엘리트의 정체성

김영민(Kim, Young-min) 고려대학교 아세아문제연구소 2013 亞細亞硏究 Vol.56 No.1

This paper seeks to review the state of the field of Chinese gentry/local elite rule and then offer an alternative approach. I will begin with an examination of existing works on Chinese gentry rule and local elite, which shall serve as a foundation for the alternative approach I will then develop. The historical reality is never as neat and clear-cut as indicated in such influential views as Oh Keum-sung’s state-centered view of Chinese gentry, Kishimoto Mio’s analysis of local society, and Western scholars’ civil society model. In the hope of contributing to a more nuanced and historically specific understanding of the governing elite in Late Imperial China, I take seriously the methodology of intellectual history. The literary collection of Zhan Ruoshui, among other sources, represents one of the best mediums through which we can explore and discuss the complex features and subtle aspects of the governing elite in Ming China. It is my contention that it is possible to formulate a more historically sensitive notion of the governing elite’s identity than the age-old notion of state-centered gentry or local elite in making sense of the state -society relationship in late imperial China.

The bridge deck section composed of a concrete slab resting on two I-beam girders are known to be susceptible to flutter instability and vortex shedding. Moreover, the cable stayed bridge in construction is more vulnerable to wind rather than in service when the free cantilever construction method is applied. This paper describes the effect of the dynamic wind loads on the bridge during construction and the effect of alternative temporary stabilizing measures. Therefore, a series of wind tunnel tests and numerical analysis were carried out to determine if any countermeasures were required.

TGA와 Py-GC/FID를 이용한 Al-MCM-48상에서 HDPE의 촉매(觸媒) 열분해(熱分解)

김영민,김승도,박영권,김지만,전종기,Kim, Young-Min,Kim, Seung-Do,Park, Young-Kwon,Kim, Ji-Man,Jeon, Jong-Ki 한국자원리싸이클링학회 2006 資源 리싸이클링 Vol.15 No.5

본 연구는 Al-MCM-48을 이용하여 HDPE를 촉매 분해하는 것으로, Al-MCM-48의 촉매 활성을 Al-MCM-41, Beta, ZSM-5와 비교하였다. Al-MCM-48를 사용한 열분해 활성은 무촉매 열분해의 활성보다 매우 높았다. 다른 촉매와 비교했을 때 Al-MCM-48의 활성화 에너지는 거의 차이가 없었다. 촉매의 점진적인 비활성화 경향도 조사하였다. ZSM-5와 Al-MCM-48은 Al-MCM-41과 Beta보다 비활성화 경향이 낮았다. Py-GC/FID(pyrolyzer)를 이용하여 열분해 생성물의 특성에 대하여 분석하였다. 그 결과 ZSM-5 촉매를 사용한 경우에는 $C_1-C_4$ 범위의 기상 생성물이 많이 생성되었다. Al-MCM-41과 Beta를 사용한 경우에는 주로 $C_5-C_{12}$ 범위의 화합물이 생성되었다. Al-MCM-48은 다른 촉매들에 비해 $C_5-C_{22}$ 범위의 오일 생성물에 대해서 높은 선택도를 나타내었다. Al-MCM-48 was used as a catalyst to decompose high density polyethylene(HDPE). Catalytic activity of Al-MCM-48 was compared with those of Al-MCM-41, Beta, and ZSM-5. Catalytic decomposition rate over Al-MCM-48 was much higher than at of non-catalytic pyrolysis only. Compared to other catalysts, Al-MCM-48 revealed the little higher activation energy value. The progressive deactivation behavior of the catalysts has also studied. ZSM-5 and Al-MCM-48 showed slower deactivation rates than Al-MCM-41 and Beta. Pyrolysis coupled with gas chromatographic separation and flame ionization detection (Py-GC/ FID) was also performed to assess the characteristics of pyrolysis products. ZSM-5 gave a higher fraction of gaseous products ($C_1-C_4$). Al-MCM-41 and Beta produced mainly $C_5-C_{12}$ products. The selectivity to oil product ($C_5-C_{22}$) obtained with Al- MCM-48 is higher an that with the other catalysts employed in this study.

투과전자현미경에 타소질 불순물의 오염 최소화를 위한 실험 조건

김영민,최주형,송경,김양수,김윤중,Kim, Young-Min,Choi, Joo-Hyoung,Song, Kyung,Kim, Yang-Soo,Kim, Youn-Joong 한국현미경학회 2009 Applied microscopy Vol.39 No.1

Contaminative artifacts such as carbonaceous materials on carbon-coated microgrids are unavoidable, which is induced by electron beam exposure inside electron microscopes. This phenomenon raise a source to produce confusing information to the samples investigated by analytical TEM, which should be alleviated as much as possible. As experimental precautions for reducing this unwanted effect, the use of $LN_2$ cooled anti-contaminator and pre-illumination of electron beam at low magnification can be helpful. Nevertheless, we should be cautious to set an illumination condition for microanalysis because the contaminative effect is dependent with the types of irradiation situations, which is well known to be a decisive factor for causing the carbonaceous artifacts. Accordingly, it is necessary that optimal illumination to minimize the contaminative effect should be selected for improving the accuracy of microanalysis. In this paper, we introduce the practical method to determine the optimal illumination condition by evaluating the contaminative effect as a function of instrumental spot size, which is directly linked with electron current density.
