한국어의 한자어 중 중국어와 동원어 관계에 있으나, 두 언어간의 기의가 일치하지 않아서, 한국인들의 중국어 학습시 난점이 되고 번역 시 오류를 유발하는 동원어를 박쥐말이라고 한다(맹주억 2004). 방향사로 구성된 박쥐말 “전후”와 이에 상응하는 중국어 어휘인 “前后”는 맹주억(2004)의 박쥐말 의미 대조 4유형 중 중국어의 의미범주가 부분 중첩인 경우에 속한다. 본고는 모국어 부정전이로 인한 박쥐말의 오도 및 회피 오류를 줄이고, 중국어 교수자들의 동원어 어휘 교육에 도움이 되기 위하여, “前后”와 “전후” 간의 기의의 차이점을 전면적으로 분석하였다. 정성적으로는, 개념적 은유 이론 (Lakoff&Johnson 1980 등)에 근거하여, “前后”와 “전후”의 각종 의미들을 공간의미(근원영역)및 추상의미(목표영역), 즉 시간/총괄범위/논리관계/서면형식 의미로 분류하여 분석하였다. 정량적으로는, 각 의미항목들이 실제 언어사용에서 차지하는 분포를 살펴보기 위하여, 한국어 및 중국어 코퍼스를 사용하여 대량의 예문에 반영된 각 의미항목의 양적 분포를 통계하였다. 코퍼스 통계 분석의 결과, 중국어 및 한국어에서 용례가 거의 발견되지 않은 “前后”와 “전후”의 기의들은 박쥐말 유형 다이어그램 중 중첩되지 않는 부분과 일치하였다. This work provides a contrastive semantic analysis on two disyllabic spatial localizers ‘qian-hou’ (‘front-back’)and ‘jeon-hu’ (‘front-back’)that are Chinese-Korean cognate. Korean learners of Chinese face difficulty in the process of learning spatial localizer ‘qian-hou’, because Language Transfer may occur between the non-overlapping meanings of Korean and Chinese cognates, as discussed in Maeng (2004)’s study on Chinese-Korean cognates, termed as ‘false friends’, i.e., cognates which have the same pronunciation, but different polysemy. Based on Lakoff & Johnson (1980)’s cognitive approach to metaphor, we explore lexical-semantics of the polysemy of spatial localizers ‘qian-hou’ and ‘jeon-hu.’ Then, using the large-sized corpus, we analyze the distribution of the usage frequency of each semantic item that are expressed by each cognate and further study the semantic and syntactic characteristics of the usages of each meaning item. Our quantitative result of the corpus analysis confirms that there are particular meaning items that are only expressed by either ‘qian-hou’ or ‘jeon-hu.’ This study aims to reveal the difference and the similarity between the polysemy of the two cognates so that the instructors of Chinese can help Korean learners to properly learn and use ‘qian-hou’.

Jinghui LI,Akitoshi ITO,Yusuke MAEDA 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10

The accuracy of robot manipulator, one of the long-standing problem, is a major issue in the industry community. The manipulator may produce kinematic errors during operation. Traditional methods require expensive equipment with complex steps to calibrate kinematic parameters. Another issue is motion planning of the manipulator, which requires a map of the workspace. However, the mapping is time-consuming. In order to employ an efficient way to accomplish kinematic calibration and offer convenience to plan the motions of the manipulator, we study a new method called SKCLAM (Simultaneous Kinematic Calibration, Localization, and Mapping), which can calibrate the kinematic parameters of an industrial manipulator and achieve 3D environmental mapping simultaneously by employing an RGBD camera attached to the end effector. In this paper, the true kinematic parameters were changed randomly to test and evaluate the effectiveness of our approach in simulation.

Beta-defensin gene (DEFB1) polymorphisms are associated with the susceptibility to chronic respiratory diseases

Yongwei Li,Xiaodan Ran,Jinghui Chen,Lu Chen,Mengzhi Wu 한국유전학회 2016 Genes & Genomics Vol.38 No.7

In the present study, we aim to investigate the correlations between polymorphisms in the DEFB1 gene and the susceptibility to chronic respiratory diseases (CRDs). Electronic searches in multiple scientific literature databases (PubMed, EBSCO, Ovid, Springerlink, Wiley, Web of Science, Wanfang database, China National Knowledge Infrastructure database and VIP database) were made to retrieve studies on the associations between DEFB1 gene polymorphisms and CRDs. We used strict inclusion criteria in the present meta-analysis. Data analyses were performed with STATA software (version 12.0; Stata Corp, College Station, TX, USA). Of 76 initiallyretrieved articles, 11 were finally incorporated into our meta-analysis, enrolling 1343 patients with CRDs (477 with chronic obstructive pulmonary disease (COPD), 305 with asthma, 286 with cystic fibrosis (CF), 130 with ventilator- associated pneumonia (VAP), 145 with pulmonary tuberculosis, and 1261 healthy controls into our metaanalysis. Our study showed that -44 C/G (rs1800972) and 1654 G/A (rs2738047) in DEFB1 are strongly associated with the increased susceptibility to CRDs. The subgroup analysis on disease types showed that the -44 C/G (rs1800972) in DEFB1 is associated with the susceptibility to COPD, VAP and CF, and the 1654 G/A (rs2738047) associated with the susceptibility to COPD and asthma. Subgroup analyses based on ethnicity indicated that -44 C/G (rs1800972) may confer increased susceptibility to CRDs in Asians but not in Caucasians. Taken together, -44 C/G (rs1800972) and 1654 G/A (rs2738047) are strongly associated with CRD susceptibility, while associations of SNPs -52 G/A (rs1799946) and -20 G/A (rs11362) with CRDs needs further investigation.

WLSD: A Perceptual Stimulus Model Based Shape Descriptor

( Jiatong Li ),( Baojun Zhao ),( Linbo Tang ),( Chenwei Deng ),( Lu Han ),( Jinghui Wu ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.12

Motivated by the Weber`s Law, this paper proposes an efficient and robust shape descriptor based on the perceptual stimulus model, called Weber`s Law Shape Descriptor (WLSD). It is based on the theory that human perception of a pattern depends not only on the change of stimulus intensity, but also on the original stimulus intensity. Invariant to scale and rotation is the intrinsic properties of WLSD. As a global shape descriptor, WLSD has far lower computation complexity while is as discriminative as state-of-art shape descriptors. Experimental results demonstrate the strong capability of the proposed method in handling shape retrieval.

Mingya Zhang,Li Liu,Shan Liang,Jinghui Li 대한금속·재료학회 2020 METALS AND MATERIALS International Vol.26 No.10

Considering the great advantage of improving the pressing speed in reducing the number of repeated deformation passes andgrain size, high-speed equal channel angular pressing (ECAP) technology has been applied to achieve the perfect distributionof grain size in a sample volume of pure copper. The microstructures and mechanical properties of pure copper sufferingECAP are investigated. The results show that the well refined grains are obtained through three stages, during which the grainreorientation and recrystallization occurs. After ECAP, the volume fraction of high-angle grain boundaries is reduced, butshows an obvious increase in the population for high-pass extruded sample. Besides, ECAP can significantly increase theproportion of the special boundaries probably through the transformation from annealing twins to deformation twins. Thetensile strength of ECAP-ed sample greatly increased to 1.87 times larger than that of the annealed bar, and then improvedslowly regardless of increasing strain. The relationship between strength and grain size still obeyed Hall–Petch formula. The cloud maps of microhardness distribution illustrated that the hardness is severely improved after the first three passes,but leveled off after that. Besides, the cloud maps also present the moderate inhomogeneity of microhardness with highervalues in the edge and lower values towards the center.

The aim of this study was to explore the chemical composition and the effect of essential oil of Angelicae dahuricae radix on a nitroglycerin (NTG)-induced rat model of migraine. The CO2 supercritical fluid extraction method was optimized for the extraction of essential oil of A. dahuricae radix (EOAD) and its chemical composition was determined. The migraine model was established by subcutaneous injection of NTG (10 mg/kg) 1 h after the last administration of EOAD. The therapeutic effect of EOAD and its underlying mechanism were assessed by monitoring behavioral changes, levels of nitric oxide (NO) in serum and brain tissues, plasma levels of calcitonin gene-related peptide (CGRP) and endothelin (ET), and ET/NO ratio. The optimal conditions for CO2 supercritical fluid extraction of EOAD, as determined by orthogonal test [L9(34)], were as follows: 2 h extraction time, 20 MPa pressure, 40°C temperature, and 30 mesh. The yield of EOAD was 1.8%. On gas chromatography–mass spectrometry, 45 peaks were found in EOAD, and 22 compounds were identified and quantified. The main constituents of EOAD were 1-dodecanol (13.71%), elemene (7.54%), palmitic acid ethyl ester (7.32%), α-pinene (6.25%), and 1-pentadecanol (6.08%). Compared with rat migraine model controls, EOAD (35, 70, and 140 mg/kg) significantly reduced the number of head shaking, head scratching, and hind leg shooting events, decreased serum and brain NO levels, decreased plasma CGRP, and increased ET levels in rats. ET/NO ratio was elevated to 28.68 in the EOAD high-dose group. EOAD ameliorates NTG-induced migraine in rats likely by modulating the levels of vasoactive substances.

Schisantherin A Improves Learning and Memory of Mice with D-Galactose-Induced Learning and Memory Impairment Through Its Antioxidation and Regulation of p19/p53/p21/ Cyclin D1/CDK4/RB Gene Expressions

Cong Liu,Weijing Sun,Ning Li,Jiaqi Gao,Chunyan Yu,Chunmei Wang,Jinghui Sun,Shu Jing,JianGuang Chen,He Li 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.7

Schisantherin A (SCA) was evaluated for possible function in restoring the learning and memory impairment induced by D-galactose in mice. ICR mice were treated with D-galactose subcutaneously (220 mg·kg−1), and followed by SCA in different doses (1.25, 2.50 and 5.00 mg·kg−1, administered orally) for 42 days. Effects of SCA on learning and memory were examined by step-through tests and Morris water maze tests. The activity of superoxide dismutase (SOD), the content of malondialdehyde (MDA) in the peripheral blood and hippocampus of mice were assayed by water-soluble tetrazolium-1 (WST-1) and thiobarbituric acid (TBA) methods. The contents of 8 hydroxy deoxy guanosine (8-OHdG) in the hippocampus of mice were detected by immunosorbent assay methods, respectively. Quantitative real-time PCR and Western Blot were respectively used to detect the expression of p19, p53, p21, cyclin D1, CDK4 and RB genes, and the phosphorylation of RB in the hippocampus of mice. We found that SCA significantly improved the learning and memory impairment induced by D-galactose in mice. After SCA treatment, SOD activity was increased and the content of MDA was decreased in both peripheral blood and hippocampus of mice. 8-OHDG content was also decreased in the hippocampus of mice. Furthermore, the expression of p19, p53 and p21 genes was reduced and the expression of cyclin D1 and CDK4 and the phosphorylation of RB protein were elevated in the hippocampus. SCA may improve the learning and memory impairment induced by D-galactose by enhancing the antioxidant capacity, and regulating the expression of p19/p53/p21/cyclinD1/CDK4 genes, and the phosphorylation of RB protein in the hippocampus of mice.

Dynamic Recrystallization Behaviors and the Texture Evolution in Mg–9Al–1Zn Alloy Produced by ECAP at Different Temperatures

Jintong Chen,Rui Sun,Guisheng Li,Ming Fang,Gaoshan Xu,Mingya Zhang,Jinghui Li 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.11

The influence of changes in temperature from 250 to 400 °C with 50 °C intervals during ECAP processing on the textureevolution and recrystallization behavior for Mg–9Al–1Zn alloy was studied. The results demonstrate that {10 1 2} extensiontwins and dislocation slip are the dominating deformation modes in low temperature (250 °C and 300 °C) ECAP processing,and those twins gradually disappear with increasing temperature. Most of the recrystallized grains are observed to exhibit(0001) poles 70°–90° away from the normal direction due to reorientation of the grains caused by twins and dislocationslips, with the texture changing from a strong basal texture to the texture component close to { 1 2 1 0} and {01 1 0}. Theproduction of ultrafine recrystallized grains in the specimens treated by ECAP at 400 °C was aided by grain fragmentationcaused by twins interaction, as well as dislocation slip and temperature increase during severe plastic deformation (SPD).
