论汉字的超语符功能

Li Yunfu,He Yuhua 세계한자학회 2015 世界漢字硏究 Vol.1 No.1

For a long time, Chinese characters have been considered merely as a tool for recording the spoken language. However, in certain contexts, Chinese characters can also convey trans-glossematic information, e.g. information incompatible with the character that is used to record its glosseme can be conveyed by some component of the character or simply by the form of the character; information that is not within the semantic category of the corresponding glosseme can be conveyed by an altered character. In fact, Chinese characters, consisting of a set of plane symbols, function as a self-contained whole, which work well with the Chinese language and keep their own features at the same time. Because of this trans-glossematic communication function, Chinese characters are not a mere copy of the Chinese language. On the contrary, they can convey messages on their own when needed. This trans-glossematic function is determined by the origin and structural features of Chinese characters. In the very beginning, the lack of correspondence between characters and glossemes, as well as the principle of representing an object by a character form that resembles it, influenced the way people understood and used the characters. The structural feature of Chinese characters, i.e. the planar composition of the characters, has rendered the alternation of characters and the separation of components possible. Therefore, there are a diversity of ways to express meaning with Chinese characters: by using just the form of a character, piecing or separating components, re-analyzing characters, adding or reducing strokes, moving strokes, or altering character forms. Expression through the use of character forms and structures is a special rhetorical device. Here we call it the rhetoric of Chinese characters.

Identification and Screening of Gene(s) Related to Susceptibility to Enterotoxigenic Escherichia coli F4ab/ac in Piglets

Li, Hejun,Li, Yuhua,Qiu, Xiaotian,Niu, Xiaoyan,Liu, Yang,Zhang, Qin Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.4

In 2004, Jorgensen and coworkers proposed the MUC4 gene as a candidate gene of enterotoxigenic Escherichia coli (ETEC) F4ab/ac receptor in piglets and a mutation of $G{\rightarrow}C$ in intron 7 of MUC4 was identified to be associated with the ETEC F4ab/ac adhesion phenotypes. In this study, we used 310 piglets of three breeds (Landrace, Large White and Chinese Songliao Black) to analyze the relationship between this mutation and the F4ab/ac adhesion phenotype. The results show that the genotypes at this site and the ETEC F4ab/ac adhesion phenotypes were not completely consistent, although they are very strongly associated. Among the individuals with genotype CC, which was identified as a resistant genotype to F4ab/ac adhesion, only 72.1% (124/172) were non-adhesive to ETEC F4ab and 77.9% (134/172) were non-adhesive to ETEC F4ac infections. This suggests that this mutation may not be the causative mutation for ETEC F4ab/ac adhesion, rather, the actual causative mutation may be in another gene closely linked to MUC4, or at aother site within the MUC4 gene. Our results also suggest that the receptors of F4ab and F4ac may be determined by two different but closely linked loci. In order to screen other genes related to F4ab/ac adhesion in piglets, the mRNA profiles from six full sib piglets, of which three were adhesive to ETEC F4ab/ac and three non-adhesive, were analyzed by suppression subtractive hybridization (SSH). One up-regulated gene, Ep-CAM, was selected for further analysis based on its role in the intestinal epithelial cells adhesion. Using real-time RT-PCR, we found that the Ep-CAM gene was significantly up-regulated in the piglets adhesive to F4ab/ac. It was mapped to SSC3q11-q14 by radiation hybrid mapping.

Determinants of Foreign Entry Mode Choice in China's Banking Sector : Institutions and Resources

Yuhua Li,Qi Yue 보안공학연구지원센터 2014 International Journal of u- and e- Service, Scienc Vol.7 No.6

This paper examines the determinants of foreign entry mode choice in China’s banking sector with a focus on strategic investment and wholly-owned subsidiaries. A conceptual framework that integrates the institution-based view and resource-based view is developed to analyze what determines foreign entry mode choice in China’s banking sector. On the institution side, this paper finds that regulation/deregulation of host country on foreign financial institutions, especially the regulation on business scope and entry requirements, affect foreign entry mode choice. On the resource side, strategic investment provides foreign financial institutions access to location-specific resources, especially customer information, and then the wholly-owned subsidiaries of financial institutions would like to utilize the location-specific resources to do their own business.

Effects of Vietnamese Plant Extracts on L-type Ca2+ Channel in Rat Ventricular Myocytes

In mammalian cardiac myocytes, influx of Ca2+ through the L-type Ca2+ channel triggers Ca2+ release from the sarcoplasmic reticulum during action potential, which induces contraction. Blockers of L-type Ca2+ channel have been used to treat several cardiac diseases including hypertension and heart failure. In the present study, we screened the effects of herbal extracts, originated from Vietnam, on L-type Ca2+ current (ICa) using whole-cell patch-clamp technique in isolated adult rat ventricular myocytes. Among seventeen extracts tested, three showed significant suppressive effects on ICa. Butanol extract of Celastrus sp. leaves, hexane extract of the whole plant of Bousingonia mekongense, and methanol extract of the stem of Phyllanthus reticulatus significantly decreased the magnitude of ICa by 9.5 ± 2.1%, 13 ± 2.5%, and 68 ± 9.2%, respectively, at the concentrations of 3 μg/ml. These results suggest a possible use of these substances as drug-candidates for cardiac diseases involved.

Hydrogen bonds, which can be divided into many types along with the deepening of research, exist inmany compounds and have certain impact on properties of substances. In this work, effect of intramolecularhydrogen bond on solvent resistance of polymeric membranes was studied from two aspects. On theone hand, the existence of intramolecular hydrogen bond on solvent resistance of polymeric membraneswas studied by constructing and shielding special hydroxyl groups in typical polymer polyurethane. Onthe other hand, content of intramolecular hydrogen bond on solvent resistance was investigated by buildingdifferent ratios of inter- and intra-molecular hydrogen bonds in polyvinyl alcohols. The structures,solvent resistance and hydrogen bonding interactions were systematically investigated by FT-IR, XRD,Ds and performances before and after immersed in solvents. Permeabilities of the membranes for practicalapplication were also characterized. The results showed that distinct type and ratio of hydrogenbonds played different role on solvent resistance. A good agreement between the swelling performancesand content of intramolecular hydrogen bond proved the positive effect of intramolecular hydrogen bondon solvent durability of polymeric membranes. In addition, polyurethane membranes exhibited goodimpermeability to water vapor, oxygen and chloride ions which showed potential application in manyfields.

떡의 역사와 꽃떡 전통의 민족문화적 의의 : 연변 ‘리향단궁정떡’의 조선족 문화정신의 발굴

리옥화(Li Yuhua),노귀남(Noh Gwinam) 한국문화융합학회 2021 문화와 융합 Vol.43 No.11

이 연구는 떡의 역사에서 꽃떡 전통을 찾아서 조선족 꽃떡의 민족문화적 가치를 밝히고자 했다. 중국조선족 사회는 지역발전을 위해 문화상품 개발에 힘쓰고 있다. 연변에서 꽃떡이 새롭게 주목받고 있는데, ‘리향단궁정떡’은최근 몇 년 사이에 중국에서 조명 받는 조선족 음식 문화상품의 하나가 되었다. 다양한 떡문화는 전통의 떡음식이 변화 발전하여 이뤄졌다. 꽃떡을 통해 민족문화의 보편성과 특징을 찾아보기위해, 이 연구는 떡의 어원과 속담에 담긴 민속적 의미를 해석했다. 떡의 민족문화적 의의를 정성(精誠), 덕성(德性), 생명성(生命性) 등 세 가지 정신으로 볼 수 있었다. 한민족은 떡을 통해서도 진선미의 문화정신을 녹여 문화콘텐츠를 만들어왔던 것이다. 떡의 재료는 무한정하므로 떡에 담긴 문화정신을 알면 새로운 상품을 개발하기는 매우 쉽다. 정신적 가치를 알고 만든 문화상품은 생활문화의 수준도 함께 끌어올릴 수 있기 때문에, 이와 같은 민족학 연구는 의의가 매우 높다. This study tries to find the tradition of flowery rice-cakes in which history and reveal thenational cultural value of Korean flowery rice-cakes. For the sake of regional development, TheKorean-Chinese society is devoting itself to the development of cultural products. In recent years,the flowery rice-cakes in Yanbian has attracted renewed attention, and “Li Xiangdan royal ricecakes” has become one of the most famous cultural commodities of Korean food in China. Diversified rice-cakes culture is formed by the change and development of traditional ricecakesdiet. In order to find the universality and characteristics of national culture through floweryrice-cakes, this study interpreted the etymology of rice cakes(‘Tteok’) and the folk meaningscontained in proverbs. The national cultural significance of rice-cakes can be regarded as threespirits: sincerity, virtue and life. The Korean-Chinese created cultural products that embody thecultural spirit of truth, kindness and beauty through rice-cakes. There is no limit to the materialof rice cakes. If we understand the cultural spirit of rice cakes, we can easily develop newproducts. Understanding the spiritual value of cultural commodities can improve the level of life,hence this kind of anthropology research has a high significance.
