Goryeoyang and Mongolpung in the 13 th – 14 th centuries

The present paper gives an overview of cultural exchanges between Goryeo and Yuan China in the 13th and 14th centuries when Goryeo was under the rule of the Yuan Dynasty. The article discusses the historical background of the cultural trends dubbed Goryeoyang (高麗樣) and Mongolpung (蒙古風) which had a great deal of influence on both peoples in many spheres of life, from everyday life to politics. By taking into account a wide variety of examples including fashion, food, lifestyle as well as the linguistic dimension, many similar customs and traditions can be identified between the two nations

The costume of ritual dance in Mongolian and Korean Buddhism

This paper investigates the diversity of costumes of Buddhist ritual dance in Mongolian and Korean Buddhism. Both the Mongolian Tsam dance and the Korean Nabi dance have developed to reflect the regional characteristics of costumes and symbolic systems and are closely related as far as the ideas of rebirth and afterlife are concerned. Both the Mongolian and the Korean dance, performed by monks, display common features that symbolise the spiritual role of the monks in guiding people on their way from birth to death. The symbolism of the ritual dance costume is related to the traditional culture, in both Mongolia and Korea, but Mongolian Tsam uses more shamanistic and decorative elements based on the ceremony of shamanism, while Korean Nabi dance shows an exceptional beauty in its self-restraint

Effects of Effective Dendrite Size on Dynamic Tensile Properties of Ti-Based Amorphous Matrix Composites

In this study, dynamic tensile properties of dendrite-containing Ti-based amorphous matrix composites were examined, and effects of dendrite size on dynamic deformation were investigated. The composites contained 73 to 76 vol pct of dendrites whose effective sizes were varied from 63 to 103 mu m. The dynamic tensile test results indicated that the ultimate tensile strength increased up to 1.25 GPa, whereas the elongation decreased to 1 pct, although the overall strength and elongation trends followed those of the quasi-static tensile test. According to the observation of dynamic tensile deformation behavior, very few deformation bands were observed beneath the fracture surface in the composite containing large dendrites. In the composite containing small dendrites, deformation bands initiated inside small dendrites propagated into adjacent dendrites through the amorphous matrix, and were crossly intersect perpendicularly in widely deformed areas, which beneficially worked for elongation as well as strength.open1131sciescopu

Creation and Control of Two-Dimensional Electron Gas Using Al-Based Amorphous Oxides/SrTiO3_3 Heterostructures Grown by Atomic Layer Deposition

The formation of a two-dimensional electron gas (2-DEG) using $SrTiO_3$ (STO)-based heterostructures provides promising opportunities in oxide electronics. We realized the formation of 2-DEG using several amorphous layers grown by the atomic layer deposition (ALD) technique at 300°C which is a process compatible with mass production and thereby can provide the realization of potential applications. We found that the amorphous $LaAlO_3$ (LAO) layer grown by the ALD process can generate 2-DEG $(\sim 1 × 10^{13}/cm^{2})$ with an electron mobility of $4–5 cm^2/V·s$. A much higher electron mobility was observed at lower temperatures. More remarkably, amorphous $YAlO_3$ (YAO) and $Al_2O_3$ layers, which are not polar-perovskite-structured oxides, can create 2-DEG as well. 2-DEG was created by means of the important role of trimethylaluminum, $Me_3Al$, as a reducing agent for STO during LAO and YAO ALD as well as the $Al_2O_3$ ALD process at 300°C. The deposited oxide layer also plays an essential role as a catalyst that enables $Me_3Al$ to reduce the STO. The electrons were localized very near to the STO surface, and the source of carriers was explained based on the oxygen vacancies generated in the STO substrate.Chemistry and Chemical Biolog

A Simulation Analysis of Effectiveness Measurement for Unmanned Ground Vehicle

In general, Unmanned Ground Vehicle like robot is one of the most effective weapon system based on leading edge technology in the modern warfare. However, its efficiency is still a difficult question to answer. Moreover, since the future warfare is getting more network centric rather than platform centric, it is even more difficult and complex to estimate its operational effectiveness. Therefore it is challenging task to develop a methodology or approach to show how efficiency it is during a ground battle of the network centric warfare. One clear distinction of this paper from others is that we are considering communication error effects depending upon terrain condition near each platform. The terrain condition is defined based on a small cell and its altitude in each cell. In this paper, we propose a new simulation framework for how to measure the operational effectiveness of unmanned ground vehicle in a small unit combat scenario. The framework is processed with following three phases. At first, we consider all relational factors for input and output variables in communication network environment of all platforms. Secondly, build a simulation model and select a measure of effectiveness based on purpose of the system performance. Thirdly, execute a simulation model and produce MOE do the output analysis. We compared the difference among three cases based on terrain condition

X-ray absorption spectroscopy elucidates the impact of structural disorder on electron mobility in amorphous zinc-tin-oxide thin films

We investigate the correlation between the atomic structures of amorphous zinc-tin-oxide (a-ZTO) thin films grown by atomic layer deposition (ALD) and their electronic transport properties. We perform synchrotron-based X-ray absorption spectroscopy at the K-edges of Zn and Sn with varying [Zn]/[Sn] compositions in a-ZTO thin films. In extended X-ray absorption fine structure (EXAFS) measurements, signal attenuation from higher-order shells confirms the amorphous structure of a-ZTO thin films. Both quantitative EXAFS modeling and X-ray absorption near edge spectroscopy (XANES) reveal that structural disorder around Zn atoms increases with increasing [Sn]. Field- and Hall-effect mobilities are observed to decrease with increasing structural disorder around Zn atoms, suggesting that the degradation in electron mobility may be correlated with structural changes.United States.
