새로 발굴된 출토문헌으로 본 ≪논어(論語)≫의 “금지긍야분려(今之矜也忿戾)”와 “공호이단(攻乎異端),사해야이(斯害也已)”에 대한 새로운 접근 모색

이위위 ( Li Weiwei ),장태원 ( Jang Taewon ) 한국중국학회 2017 중국학보 Vol.82 No.-

20세기 들어 今本 ≪論語≫와 관련된 출토문헌이 계속 발견되고 있다. 이들 주요 출토문헌으로는 敦煌과 吐魯番 지역에서 출토된 唐寫本 ≪論語≫와 河北 定縣의 漢墓에서 출토된 漢代 竹簡 寫本 ≪論語≫를 비롯한 戰國 시기 郭店簡과 上博簡에 흩어져 보이는 ≪論語≫와 관련된 구절 그리고 새로 발견된 북한 평양의 貞柏洞에서 나온 漢代 竹簡 殘本 ≪論語≫와 懸泉의 漢簡 ≪子張≫篇 殘簡 등이 있다. 본문은 이상의 출토문헌과 今本 ≪論語≫의 경문을 이용하여 ≪論語·陽貨≫의 “古之矜也廉, 今之矜也忿戾”의 “忿戾”에 관한 각종 異文 자료들을 비교 검토하면서 “也”의 문법적 기능을 근거로 하여 “今之矜也忿戾” 구절이 당시의 언어 환경에서 정확하게 어떤 의미였는지에 관하여 새로운 접근을 모색하고자 한다. 또한 “攻乎異端, 斯害也已”에 대해서 학계에는 많은 이설이 존재하고, 그 관점의 차이도 아주 커다. 본문은 지금까지의 연구 성과를 토대로 이 구절을 분석해보고 나아가 출토문헌 ≪論語≫의 異文 자료를 활용해 새로운 접근을 시도한다. This paper is based on the contrasting of the different characters in these unearthed documents about the Analects of Confucius with the current version. Secondly, We hope to make full use of the different characters of unearthed documents about the Analects of Confucius. According to the different characters of “fen li” that contrasting the unearthed documents that mentioned above with the current version of the Analects of Confucius about “gu zhi jin ye lian, jin zhi jin ye fen li” in Yang Huo, and the grammatical function of “ye” in the sentence of “Jin zhi jin ye fen li”, We are trying to reinterpret “Jin zhi jin ye fen li” scientifically. With the help of the different characters that contrasting the unearthed documents with the current version of the Analects of Confucius, strive to draw a more reasonable conclusion about “gong hu yi duan si hai ye yi”.

A Comparative Study on the Insulation Ageing of 10 kV XLPE Cable via Accelerated Electrical Test and Accelerated Water Tree Test

Li Weiwei,Zheng Wenyue,Ren Lulu,Li Huan,Zhao Xuetong,Wang Can,Li Jianying 대한전기학회 2022 Journal of Electrical Engineering & Technology Vol.17 No.1

Medium and high voltage XLPE cables were widely used in urban distribution network. The electric-thermal eff ect of the cable conductor and water in the running environment are two important factors that cause ageing of cable insulating material. In this work, accelerated electrical test (AET) and accelerated water tree test (AWTT) on 10 kV XLPE cable were carried out for 1440 h, 2880 h and 4320 h, respectively. The physicochemical and dielectric properties of both aged and unaged XLPE samples were tested. Physicochemical investigation of Fourier Transform Infrared (FTIR) spectroscopy and X-Ray Diff raction (XRD) show that higher carbonyl groups index, and lower crystallinity of the XLPE insulating materials were generated in AWTT process than that in AET process. The thermal decomposition process of the AWTT XLPE are complicated, presenting a multi-peak phenomenon in the diff erential thermogravimetry (DTG) curve. The insulating strength of the samples after AWTT is monotonically decreased from 23.03 kV to 21.74 kV with ageing time. The dielectric properties show that the permittivity and dielectric loss of AWTT samples increased more severely than that of AET samples, with a new dielectric relaxation peak appearing at around 100 Hz. The combination of physicochemical and dielectric results reveals that AWTT process leads to more serious degradation for XLPE insulating materials. A schematic illustration is given to elucidate the development of micro defects in XLPE during the AET and AWTT processes.

Huang, Sanwen,Li, Ruiqiang,Zhang, Zhonghua,Li, Li,Gu, Xingfang,Fan, Wei,Lucas, William J,Wang, Xiaowu,Xie, Bingyan,Ni, Peixiang,Ren, Yuanyuan,Zhu, Hongmei,Li, Jun,Lin, Kui,Jin, Weiwei,Fei, Zhangjun,Li Nature Publishing Group 2009 Nature genetics Vol.41 No.12

Cucumber is an economically important crop as well as a model system for sex determination studies and plant vascular biology. Here we report the draft genome sequence of Cucumis sativus var. sativus L., assembled using a novel combination of traditional Sanger and next-generation Illumina GA sequencing technologies to obtain 72.2-fold genome coverage. The absence of recent whole-genome duplication, along with the presence of few tandem duplications, explains the small number of genes in the cucumber. Our study establishes that five of the cucumber's seven chromosomes arose from fusions of ten ancestral chromosomes after divergence from Cucumis melo. The sequenced cucumber genome affords insight into traits such as its sex expression, disease resistance, biosynthesis of cucurbitacin and 'fresh green' odor. We also identify 686 gene clusters related to phloem function. The cucumber genome provides a valuable resource for developing elite cultivars and for studying the evolution and function of the plant vascular system.

Study on Aboveground Biomass of Pinus sylvesris var. mongolica Plantation Forest in Northeast China Based on Prediction Equations

Weiwei Jia,Lu Li,Fengri Li 강원대학교 산림과학연구소 2012 Journal of Forest Science Vol.28 No.2

A total of 45 Pinus sylvestnis var. mongolica trees from 9 plots in northeast China were destructively sampled to develop aboveground prediction equations for inventory application. Sampling plots covered a range of stand ages (12-47-years-old) and densities (450-3,840/ha). The distribution of aboveground biomass of whole-trees and tree component (stems, branches and leaves) of individual trees were studied and 4 equations were developed as functions of diameter at breast height (DBH), total height (HT). All the equations have good estimation effect with high prediction precision over 90%. Forest biomass was estimated based on the individual biomass prediction equations. It was found forest biomass of all organs increased with the increasing of stand age and density. And the period of 45-50 years was the suitable harvest time for Pinus sylvesris plantation.

Various Seeding Methods for Tissue Development of Human Umbilical-cord-derived Mesenchymal Stem Cells in 3-Dimensional PET Matrix

Weiwei Li,Min Li,Yantian Chen,Shaoming Zhang,Nian Min Qi 한국생물공학회 2014 Biotechnology and Bioprocess Engineering Vol.19 No.1

Mesenchymal stem cells derived from humanumbilical cords (hUCMSCs) are attractive as a new cellsource for tissue engineering. It is essential to investigateand optimize the seeding process of these cells for thesuccess of cell culture and tissue regeneration in vitro. In thisstudy, a static seeding method (SSM), a centrifugal seedingmethod (CSM), and a novel method-cycling filtrationseeding method (CFSM) are evaluated in terms of seedingefficiency, cell damage, and distribution inside the scaffolds,cell proliferation, and osteogenic differentiation. Cells wereseeded on three-dimensional (3-D) nonwoven PET discs ata density of 1×104 cells/disc, followed by 21 days of cellculture and 20 days of osteogenic differentiation. Cellsgrown in 3-D conditions exhibited higher metabolic activitythan those grown on a 2-D control surface. The CSM andCFSM groups showed higher seeding efficiency, proliferationcapacity, and differentiation potential. H&E staining indicateda more uniform spatial distribution of cells in CFSMgroups. LDH level measurements suggested that more celldamage was caused by the CFSM process. Above all, theresults showed that the cells maintained their proliferationability and differentiation potential ex vivo during approximately7 weeks of culture. The CSM and CFSM arerecommended for hUCMSC tissue engineering, althoughthe seeding parameters still require further investigationand optimization.

Effect of Cu-Coated Short Carbon Fibers on the Mechanical and Electrical Properties of the Epoxy Composites

Weiwei Li,Lei Liu,Bin Shen,Yating Wu,Wenbin Hu 한국고분자학회 2012 Macromolecular Research Vol.20 No.4

In this study, short carbon fiber (SCF)-reinforced epoxy composites were prepared through changing of the fiber content (0.1-0.7 wt%). An electrodeposition process was used to produce Cu-coated SCFs. To investigate the effect of Cu-coated SCFs on the composite mechanical and electrical properties, we prepared two kinds of reinforcements:SCFs treated by 400 oC (400 oC-treated SCFs) and Cu-coated SCFs (Cu-SCFs). Fracture characteristics of the composites revealed that the Cu coating and the epoxy matrix had a better interface, meaning that the tensile and bending strength results were better in epoxy/Cu-SCFs composites than those in epoxy/400 oC-treated SCFs composites. The 400 oC-treated SCFs decreased the electrical resistivity of the epoxy composites compared to the pure epoxy. However the epoxy/Cu-SCFs composites had lower electrical resistivity than epoxy/400 oC-treated SCFs with the same fiber content.

( Li Weiwei ),이선웅 ( Yi Seon-ung ) 한민족어문학회 2018 韓民族語文學 Vol.0 No.80

본고는 대조언어학의 관점에서 한·중 수 표현 대조를 통해 정수 표현, 서수 표현, 개략수 표현에 어떤 공통점과 차이점이 있는지를 살펴볼 것이다. 수 표현은 수사에 의해 표현되는 수량 범주이다. 대부분의 선행 연구는 수사와 수 표현을 구분하지 않고 모두 수사 체계에 포함시켰는데 본고는 수사와 수 표현을 구분하는 입장에서 수사 체계와 수 표현 체계를 나누어 고찰하였다. 수사의 구성에 주목하여 수사 체계를 구축하였고 수사를 사용하여 특정한 수량 범주를 표현하는 것을 수 표현으로 분류하여 수 표현 체계를 구축하였다. 한·중의 수 표현 체계에는 정수 표현, 서수 표현, 개략수 표현을 포함한 다. 각 범주에서 한·중의 표현 양상을 자세히 살펴보았다. 한·중의 정수 표현에서는 중국어에는 보조수사 ‘零(0), 兩(2)’이 있는 등 한국어와 다소간 차이점을 보였다. 서수 표현에 있어서는 ‘수사+명사’의 방법으로 양수와 서수를 모두 나타낼 수 있음을 한국어와 중국어에서 모두 확인하였다. 개략수 표현에 있어서는 한국어보다 중국어의 개략수 표현 방법이 더 다양하다. 본고는 표현론적 관점에서 한·중의 수 표현의 공통점과 차이점을 추출하여 중국인 학습자에 대한 한국어 교육에도 충실한 자료가 될 것이라 생각한다. The purpose of this paper is to contrast the numerical expressions used in the Korean and Chinese numeral systems. The numerical expression in this paper is the quantity category expressed by the numerals. In the previous study, numerals and numerical expressions were both included in the numeral system. We constructed a microscopic numeral system of Korean and Chinese numbers by paying attention to the constitution principle of the numerals. We also constructed a numerical expression system for Korean and Chinese numbers by expressing quantities using macroscopic numerals. The system includes basic numerals, unit numerals, and union numerals from the Korean numeral system, and basic numerals, unit numerals, auxiliary numerals, and union numerals from the Chinese numeral system. Korean and Chinese numerical expressions include integer expressions, ordinal expressions, and approximate numerical expressions. In this paper, the integer expressions, the ordinal expressions, and the approximate expressions used in the Korean and Chinese numerical expression systems are compared; the differences and common points between the expressions in each category are revealed.

Long Carbon Fibers Reinforced Rigid Polyurethane Composites: An Investigation In Strength and Toughness

Weiwei Li,Jie Yang,Xiaojing Liu 한국섬유공학회 2020 Fibers and polymers Vol.21 No.7

High-performance polyurethane materials are attracting more and more attention. In this work, a cooperativeimprovement of strength and toughness of rigid polyurethane (RPU) composites was achieved. 1.0 wt% long carbon fibers(LCFs) reinforced RPU composites were prepared and the effects of fiber oxidation treatment were studied. The resultsindicated that the surface roughness and wettability of LCFs were both increased, which could provide better physicalbonding between LCFs and RPU matrix. Moreover, the increasing -OH groups on the fiber surface would react with RPU toform chemical bond. With the strengthened physical and chemical bonds, the interface of LCFs/RPU composites has beeneffectively improved. The mechanical properties showed that compared with pure RPU, the tensile strength, tensile modulus,bending strength, bending modulus, and impact strength of oxidized LCFs/RPU composites were increased by 171.1 %,814.3 %, 29.1 %, 125.8 % and 110.1 %, respectively. Interlaminar shear strength (ILSS) was also increased by 65.1 %. Dynamic thermomechanical analysis (DMA) and scanning electron microscope (SEM) indicated the positive effects of theoxidation treatment on the interfacial bonding between LCFs and RPU matrix.
