While doing business in China foreign companies occasionally find themselves embroiled in disputes with Chinese individuals, companies or the Chinese Government. There are three primary ways to resolve a commercial dispute in China are negotiation, arbitration and litigation. The best way of dispute resolution is negotiation as it is the least expensive method and the working relationship of both parties concerned in dispute. But negotiations do not always give rise to resolution. Arbitration is the next choice. Unless the parties concerned can agree to resort to arbitration after the dispute has arisen, the underlying contract namely, sales contract or separate agreement must show that disputes will be resolved by arbitration. Agreements to arbitration specify arbitration body and governing law. There are two Chinese government -sponsored arbitration bodies for handling cases involving at least one foreign party: China International Economic and Trade Arbitration Commission(CIETAC) and China Maritime Arbitration Commission(CMAC) for maritime disputes. Contracts regarding foreign companies doing business in China often designate CIETAC arbitration. CIETAC distinguishes between two kinds of dispute resolutions, foreign-related arbitration and domestic arbitration. For a dispute to be classified as foreign-related arbitration, one of the companies must be a foreign entity without a major production facility or investment in China. CIETAC has published rules which govern the selection of a panel if the contract does not specify how the choice of arbitration will be handled. CIETAC's list of arbitrators for foreign-related disputes, from which CIETAC's arbitrators must en chosen, includes may non-Chines arbitrators. But many foreign experts believe that some aspects of CIETAC needs to be improved. The purpose of this paper is to improve the understanding of arbitration in China, CIETAC by way of studying the current situation and improvement of international commercial arbitration in China.

영상의 표시는 PACS 및 디지털 의료 영상계에서 중요한 요소이다. 동일한 디지털 데이터에 대한 영상의 질은 디스플레이 장치의 물리적 특성, 최적화된 설정 및 교정, 주위 불빛 조건 등에 의하여 영향을 받는다. 디스플레이 장치는 사용시간에 따라서 휘도 감소 및 설정값들의 변화에 의하여 성능이 저하된다. 디스플레이 시스템의 성능이 지속적으로 저하되기 때문에 일정한 주기마다. 정도관리를 수행하여야한다. 정도관리 효과를 평가하기 위하여 진단에 사용되는 10대의 평판 LCD 디스플레이 장치를 선택하였으며, 설정값 교정 전과 후에 휘도 반응, 휘도 공간 의존도, 분해능, 그리고 색도 변화를 정량적으로 측정하여 평가하였다. 정도관리 효과는 휘도 반응과 휘도 공간 의존도 테스트에서 다소 큰 변화가 있었으나 분해능 및 디스플레이 색도에서의 영향은 크지 않았다. 디스플레이 장치의 주기적인 정도관리는 의료영상을 일관성 있게 표시하기 위하여 필수적이다. 본 연구 결과는 의료용 디스플레이 장치의 정도관리에 대한 항목 선정 및 주기를 결정하는 데 중요한 역할을 할 수 있을 것이다.

Organic light-emitting device (OLED) have become very attractive due to their potential application in flat panel displays. One important problem to be solved for practical application of full-color OLED is development of three primary color (Red, Green and Blue) emitting molecule with high luminous operation. Particularly, the development of organic materials for blue electroluminescence (EL) lags significantly behind that for the other two primary colors. For this reason, Flu-Si was synthesized and characterized by means of high-resolution mass spectro metry and elemental analyses. Flu-Si has the more wide optical band gap (Eg = 3.86) than reference material (Cz-Si, Eg = 3.52 eV). We measured the photophysical and electrochemical properties of Flu-Si. The HOMO-LUMO levels were estimated by the oxidation potential and the onset of the UV-Vis absorption spectra. The EL properties were studied by the device fabricated as a blue light emitting material with FIrpic.

High-resolution spectroscopic observations of the eclipsing binary system RR Lyn were made using the 1.8 m telescope at the Bohuynsan Optical Astronomical Observatory in Korea. The spectral resolving power was R = 82,000, with a signal to noise ratio of S/N > 150. We found the effective temperatures and surface gravities of the primary and secondary components to be equal to $T_{eff}$ = 7,920 & 7,210 K and log(g) = 3.80 & 4.16, respectively. The abundances of 34 and 17 different chemical elements were found in the atmospheric components. Correlations between the derived abundances with condensation temperatures and the second ionization potentials of these elements are discussed. The primary component is a typical metallic line star with the abundances of light and iron group elements close to solar values, while elements with atomic numbers Z > 30 are overabundant by 0.5-1.5 dex with respect to solar values. The secondary component is a ${\lambda}$ Boo type star. In this type of stars, CNO abundances are close to solar values, while the abundance pattern shows a negative correlation with condensation temperatures.

R Canis Majoris is a bright, short-period ($1^d$.1359) Algol-type eclipsing binary. For a long time, it was considered to be a low-mass binary star with $M_1=1.1M_{\odot}$ and $M_2=0.17M_{\odot}$ primary and secondary components, respectively (Tomkin, 1985). Glazunova, Yushchenko & Mkrtichian (2009) found new masses for the primary and secondary components of $M_1=1.81M_{\odot}$ and $M_2=0.23M_{\odot}$, respectively and resolved a long-standing problem with the low masses of components for this binary. Budding and Butland (2011) confirmed the results of Glazunova, Yushchenko & Mkrtichian and obtained improved orbits and masses. New spectroscopic observations of R CMa were done during 8 nights on December 2012 with the 2.4-meter telescope of the Thai National Observatory (TNO) and fibre-fed medium resolution echelle spectrograph. We obtained new, accurate orbital radial velocities of the two components of this binary system. Results of these investigations and the new orbital parameters are presented.

총일차생산량(GPP, Gross Primary Productivity)은 생태계의 유기물 생산량을 나타내는 지표로써 생태계 생산성과 안정성을 파악할 수 있는 중요한 지표로 알려져 있다. GPP를 산출하는 대표적인 방법에는 다중 센서를 탑재한 원격 탐사 자료를 활용하는 방법과 플럭스타워를 통해 관측한 에디공분산을 분석하는 방법이 있다. 본 연구에서는 Landsat과 MODIS와 같이 시공간 해상도가 다른 원격 탐사 자료들을 기반으로 초고해상도 GPP 자료를 산출하기 위한 공간자료 융합 연구를 수행하였다. 이를 위해 GAN(Generative Adversarial Networks)과 같은 머신러닝 알고리즘을 활용하였으며 최종적으로 산정된 GPP 정보는 설마천과 청미천 등에 설치된 플럭스타워로부터 획득한 자료와의 비교·검증을 통해 평가되었다. 본 연구의 성과는 향후 증발산 자료, 생태계 호흡량 자료 등과의 조합을 통해 얻을 수 있는 물이용효율(WUE, Water Use Efficiency), 탄소이용효율(CUE, Carbon Uptake Efficiency)과 같은 지표 산정 시 적극 활용될 수 있을 것으로 기대된다.

As the number of spectral bands of high spectral resolution data increases, the capability to detect more detailed classes should also increase, and the classification accuracy should increase as well. Often, it is impossible to access enough training pixels for supervise classification. For this reason, the performance of traditional classification methods isn't useful. In this paper, we propose a new model for classification that operates based on decision fusion. In this classifier, learning is performed at two steps. In first step, only training samples are used and in second step, this classifier utilizes semilabeled samples in addition to original training samples. At the beginning of this method, spectral bands are categorized in several small groups. Information of each group is used as a new source and classified. Each of this primary classifier has special characteristics and discriminates the spectral space particularly. With using of the benefits of all primary classifiers, it is made sure that the results of the fused local decisions are accurate enough. In decision fusion center, some rules are used to determine the final class of pixels. This method is applied to real remote sensing data. Results show classification performance is improved, and this method may solve the limitation of training samples in the high dimensional data and the Hughes phenomenon may be mitigated.

Large area matrix-addressed image detectors are a recent technology for x-ray imaging with medical diagnostic and other applications. The imaging properties of x-ray pixel detectors depend on the quantum efficiency of x-rays, the generated signal of each x-ray photon and the distribution of the generated signal between pixels. In a phosphor coated detector the light signal is generated by electrons captured in the phosphor screen. In our study we simulated the lateral spread distributions for phosphor coupled detector by Monte Carlo simulations. Most simulations of such detectors simplify the setup by only taking the conversion layer into account neglecting behind. The Monte Carlo code MCNPX has been used to simulate the complete interaction and subsequent charge transport of x-ray radiation. This has allowed the analysis of charge sharing between pixel elements as an important limited factor of digital x-ray imaging system. The parameters are determined by lateral distribution of x-ray photons and x-ray induced electrons. The primary purpose of this study was to develop a design tool for the evaluation of geometry factor in the phosphor coupled optical imaging detector. In order to evaluate the spatial resolution for different phosphor material, phosphor geometry we have developed a simulation code. The developed code calculates the energy absorption and spatial distribution based on both the signal from the scintillating layer and the signal from direct detection of x-ray in the detector. We show that internal scattering contributes to the so-called spatial resolution drop of the image detector. Results from the simulation of spatial distribution in a phosphor pixel detector are presented. The spatial resolution can be increased by optimizing pixel size and phosphor thickness.
