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.

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.

Objectives : This study presents a scientific basis for the establishment of an environmental health contingency plan for dealing with accidental coastal oil spills and suggests some strategies for use in an environmental health emergency. Methods : We reviewed the existing literature, and analyzed the various fundamental factors involved in response strategies for oil spill. Our analysis included data derived from Hebei Spirit oil spill and used air dispersion modeling. Results : Spill amounts of more than 1,000 kl can affect the health of residents along the coast, especially those who belong to vulnerable groups. Almost 30% of South Korean population lives in the vicinity of the coast. The area that is at the highest risk for a spill and that has the greatest number of people at risk is the stretch of coastline from Busan to Tongyeong. The most prevalent types of oil spilt in Korean waters have been crude oil and bunker-C oil, both of which have relatively high specific gravity and contain volatile organic compounds, polycyclic aromatic hydrocarbons, and metals. In the case of a spill of more than 1,000 kl, it may be necessary to evacuate vulnerable and sensitive groups. Conclusions : The government should establish environmental health planning that considers the spill amount, the types of oil, and the distance between the spot of the accident and the coast, and should assemble a response team that includes environmental health specialists to prepare for the future oil spill.

Floating debris in large quantities from land during heavy rainfall has adverse social, economic, and environmental impacts, but the monitoring system for the concentration area and amount is insufficient. In this study, we proposed an efficient monitoring method for floating debris entering the river during heavy rainfall in Daecheong Lake, the largest water supply source in the central region, and applied remote sensing techniques to estimate the standing-stock of floating debris. To investigate the status of floating debris in the upper of Daecheong Lake, we used a tracking buoy equipped with a low-orbit satellite communication terminal to identify the movement route and behavior characteristics, and used a drone to estimate the potential concentration area and standing-stock of floating debris. The location tracking buoys moved rapidly during the period when the cumulative rainfall for 3 days increased by more than 200 to 300 mm. In the case of Hotan Bridge, which showed the longest distance, it moved about 72.8 km for one day, and the maximum moving speed at this time was 5.71 km/h. As a result of calculating the standing-stock of floating debris using a drone after heavy rainfall, it was found to be 658.8 to 9,165.4 tons, with the largest amount occurring in the Seokhori area. In this study, we were able to identify the main concentrations of floating debris by using location-tracking buoys and drones. It is believed that remote sensing-based monitoring methods, which are more mobile and quicker than traditional monitoring methods, can contribute to reducing the cost of collecting and processing large amounts of floating debris that flows in during heavy rain periods in the future.

Nurturing students`` scientific creativity is considered an important element in science education in Korea. The study aims to explore patterns displayed by well-known scientists in their quest for problem finding. Each case of scientists`` course of problem solving is described in terms of historical background, a process of problem finding, and a process of problem solving. There are five patterns from ten scientists which are as follows: Pattern 1 is that scientists find problems from insufficiencies and/or errors from explanation of theories at the time and the related cases are A. Lavoisier, G. Mendel, and J. Watson. Pattern 2 shows that scientists find a problem because of strange phenomena unexplained by theories at the time, and here important case studies are E. Rutherford and W. Rontgen. Pattern 3 demonstrates that scientists find a problem from analogical reasoning between known theories and unknown science phenomena. The cases include S. Carnot and T. Young. Pattern 4 points to the fact that scientists find a problem while they utilize a newly invented experimental instrument. Here, G. Galilei is an important example. Pattern 5 establishes that scientists happen to find a problem while they conduct research projects. The works of M.Faraday and J. Kepler are prominent case studies related to this pattern.

강합성 2주형 사장교의 시공중 내풍 안정성 확보 방안 연구

김영민,김대영,Kim,Young-Min,Kim,Dae-Young 한국방재학회 2008 한국방재학회 학술발표대회논문집 Vol.2008 No.1

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.

초고전압 투과전자현미경의 원격시범운영

김영민,김진규,김윤중,허만회,권경훈,Kim, Young-Min,Kim, Jin-Gyu,Kim, Youn-Joong,Hur, Man-Hoi,Kwon, Kyung-Hoon 한국현미경학회 2004 Applied microscopy Vol.34 No.1

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.

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.
