Xue Jun DENG,박현재 한국무역상무학회 2022 貿易商務硏究 Vol.93 No.-

The main objective of this study is to identify the antecedents of the purchase intention of Korean millennial consumers on high involvement products made in China, focusing on the personal characteristics of the millennial consumers in Korea. 203 samples were finally used for this analysis using SPSS program. The results of the study are as follows ; First, Openness and extroversion in personal traits have positive (+) effect on customer satisfaction. Second, perceived social risk has been found to play a mediating role in the relationship between extroversion and customer satisfaction. Third, The customer satisfaction has positive (+) effect on purchase intention. As a result, companies which want to sell high-involvement products made in China are found to be effective in focusing on Korean millennial consumers with open personality characteristics and high levels of extroversion, when establishing marketing strategies in Korea. Furthermore, firms which want to sell high-involvement products made in China should also consider managing perceived social risk which plays a mediating role. 한국 소비자들은 보조배터리와 같은 저관여 중국산제품은 잘 구매하지만 노트북, 자동차와 같은 고관여 중국산 제품은 구매하기를 주저한다. 따라서 본 연구는 기존 선행연구의 한계점을 보완하고자 미래 소비의 중심으로 떠오를 한국 밀레니얼의 개인적 특성을 중심으로 고관여제품의 구매의도에 영향을 미치는 선행요인을 파악해보고자 하였다. 연구모형의 검증결과, 밀레니얼 소비자의 개방성과 외향성은 고객만족도에 유의한 영향을 미친다는 것을 알 수 있었다. 또한, 외향성과 고객만족도 사이에 지각된 사회적위험이 매개효과를 보이는 것으로 나타났다. 이상의 연구결과를 바탕으로 이론적, 실무적으로 유용한 시사점을 제시하고자 하였다.

Disambiguate Chinese Word Sense Based on Linguistics Knowledge

Chun-Xiang Zhang,Long Deng,Xue-Yao Gao,Zhi-Mao Lu 보안공학연구지원센터 2014 International Journal of Database Theory and Appli Vol.7 No.6

Word sense disambiguation (WSD) is important to many application problems in natural language processing fields, such as machine translation, parsing analysis and information retrieval. In this paper, we propose a new method to determine correct sense categories of Chinese words based on linguistics knowledge. The left word string and the right word string around the ambiguous word are respectively analyzed. Their syntactic structures are obtained for determining its intended sense. Syntactic category and part of speech are extracted as disambiguation features. A naive bayesian model is used as the classifier. Experimental results showed that the accuracy rate of classification arrives at 64%. The performance of disambiguation is improved.

The phase structure, photoluminescence properties and thermal stability of the phosphor were investigated in detail. The phosphor shows dominant emission peak at 613nm belonging to the <SUP>5</SUP>D<SUB>0</SUB>→<SUP>7</SUP>F<SUB>2</SUB> electric dipole transition under 396nm excitation. The luminescence intensity keeps increasing with increasing the content of Eu<SUP>3+</SUP> to 15mol%, and the critical transfer distance of Eu<SUP>3+</SUP> was calculated to be 14Å.

The Effect of Transformation on the Virulence of Streptococcus pneumoniae

Xue-Mei Zhang,Yi-Bing Yin,Dan Zhu,Bao-De Chen,Jin-Yong Luo,Yi-Ping Deng,Ming-Fang Liu,Shu-Hui Chen,Jiang-Ping Meng,Kai Lan,Yuan-Shuai Huang,Ge-Fei Kang 한국미생물학회 2005 The journal of microbiology Vol.43 No.4

Although pneumococcus is one of the most frequently encountered opportunistic pathogen in the world, the mechanisms responsible for its infectiveness have not yet been fully understood. In this paper, we have attempted to characterize the effects of pneumococcal transformation on the pathogenesis of the organism. We constructed three transformation-deficient pneumococcal strains, which were designated as Nos. 1d, 2d, and 22d. The construction of these altered strains was achieved via the insertion of the inactivated gene, comE, to strains 1, 2 and 22. We then conducted a comparison between the virulence of the transformation-deficient strains and that of the wild-type strains, via an evaluation of the ability of each strain to adhere to endothelial cells, and also assessed psaA mRNA expression, and the survival of hosts after bacterial challenge. Compared to what was observed with the wild-type strains, our results indicated that the ability of all of the transformation-deficient strains to adhere to the ECV304 cells had been significantly reduced (p < 0.05), the expression of psaA mRNA was reduced significantly (p < 0.05) in strains 2d and 22d, and the median survival time of mice infected with strains 1d and 2d was increased significantly after intraperitoneal bacterial challenge (p < 0.05). The results of our study also clearly indicated that transformation exerts significant effects on the virulence characteristics of S. pneumoniae, although the degree to which this effect is noted appears to depend primarily on the genetic background of the bacteria.

Analysis of thermally induced vibration of cable-beam structures

Deng, Han-Qing,Li, Tuan-Jie,Xue, Bi-Jie,Wang, Zuo-Wei Techno-Press 2015 Structural Engineering and Mechanics, An Int'l Jou Vol.53 No.3

Cable-beam structures characterized by variable stiffness nonlinearities are widely found in various structural engineering applications, for example in space deployable structures. Space deployable structures in orbit experience both high temperature caused by sun's radiation and low temperature by Earth's umbral shadow. The space temperature difference is above 300K at the moment of exiting or entering Earth's umbral shadow, which results in structural thermally induced vibration. To understand the thermally induced oscillations, the analytical expression of Boley parameter of cable-beam structures is firstly deduced. Then, the thermally induced vibration of cable-beam structures is analyzed using finite element method to verify the effectiveness of Boley parameter. Finally, by analyzing the obtained numerical results and the corresponding Boley parameters, it can be concluded that the derived expression of Boley parameter is valid to evaluate the occurrence conditions of thermally induced vibration of cable-beam structures and the key parameters influencing structural thermal flutter are the cable stiffness and thickness of beams.

PARALLEL IMAGE RECONSTRUCTION FOR NEW VACUUM SOLAR TELESCOPE

Xue-Bao Li,Feng Wang,Yong Yuan Xiang,Yan-Fang Zheng,Ying Bo Liu,Hui Deng,Kai-fan Ji 한국천문학회 2014 Journal of The Korean Astronomical Society Vol.47 No.2

Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.

Separate calculations of the two currents driven by electron cyclotron waves

Deng Sheng,Zheng Ping-wei,Gong Xue-yu,Lu Xing-qiang 한국물리학회 2022 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.81 No.8

The expressions of both the Fisch–Boozer and Ohkawa currents are constructed, and a feasible and efcient calculation method is given. Simulation results of the Fokker–Plank code verify the expressions and the calculation method. We calculate and separate the Ohkawa and Fisch–Boozer currents on a single magnetic fux surface of the of-axis position. The Ohkawa current drive mechanism can be made dominant over the Fisch–Boozer mechanism to achieve a high driven current. This can be done by adjusting the parameters of electron cyclotron waves to make the power deposited in the of-axis region of the low-feld side.
