朝鮮時代漢語敎科書與近代漢語硏究

汪維輝 연세대학교 인문과학연구소 2002 人文科學 Vol.84 No.-

引言 중한양국은 매우 오랫동안 교류해왔지만 두 나라의 언어 체계가 틀려서 교류에 있어 언어가 하나의 장벽이 되어왔다. 본고에서는 당시 중국어를 배우기 위한 한국에서의 중국어 교과서에 대한 소개를 하고 이러한 교과서의 연구자료상 가치와 그 연구현황에 대해 토론하고자 한다. 2.조선시대의 중국어 교과서 2.1 「老乞大」, 「朴通事」 가장 유명하고 가장 오래된 중국어 교과서로 그 제작연대는 중국의 원 말기의 至元연간으로 추정된다. 정통 중국어 입말이 위주이며 蒙古語의 영향도 보인다. 그 내용은 일상회화로 여행, 무역, 풍속관습, 典章制度 등을 포괄하고 있는데 『朴通事』의 내용이 『老乞大』보다 광범위하고 심도가 깊어 『朴通事』가 고급과정이라면 『老乞大』는 초급과정에 속한다. 특히 최근 한국에서 개인이 소장했던 古本 『老乞大』가 발견되었는데, 이는 앞으로 주요한 연구주제가 될 것으로 보인다. 2.2 『訓世評語』 (上·下, 1473/1518) 1473년 6월에 편찬되었으며 65가지의 고사가 수록되었는데, 名賢과 節婦에 관한 이야기가 주 내용이며 일부 유머가 넘치는 전설도 있다. 이 책을 다른 중국어 교과서와 체례상 많은 차이를 보이는데 이는 작가 李邊의 독창적인 작품이라는 것을 말해준다. 이 책은 대화체가 아니라 이야기를 하는 문체로 言文對照를 해놓았다. 사상적인 면을 중시하는 점에서 학문적 소양이 풍부한 학자가 쓴 희귀한 중국어교과서 자료로 보인다. 2.3 『華音啓蒙諺解」 (上 ·下, 1883) 李應憲의 저작 『業音啓蒙』에 대한 諺解本으로 모두 40페이지에 달한다. 이책은 '부열'라는 용어사용과 俗字가 많이 나타나는 점이 주의할 만하다. 2.4 『이니귀성』과 『學淸』 『이니귀성』은 1冊, 34페이지에 달한다. 책제목은 회화부분의 한 문장을 따서 만들었다. 『華音啓蒙』과 같이 북방 방언투의 사투리가 있는데 『이니귀성』과 『華音啓蒙』은 내용과 연대가 비슷하며 방언도 유사하여 비교연구의 가치가 있다고 하겠다. 『學淸』은 『이니귀성』의 手記本으로 '學習淸語'를 줄인 것으로 회화부분에는 『이니귀성』 1, 3부분만 수록되어있다. 위의 『華音啓蒙諺解』, 『이니귀성』, 『學淸』은 아직 연구가 되어있지 않다. 3. 자료의 가치와 연구상황 近代中國語의 分期에 대해서는 아직 일치된 견해가 없는 실정이다. 그러나 조선시대의 중국어교과서는 중국 근대중국어시기,즉 元, 明, 淸 三代의 중국어발전사상 중요한 자료가 된다. 『老乞大』의 연구상황을 간략히 요약하면 다음과 같다. 3.1 음운 『老乞大諺解』와 『朴通事諺解』로 明代의 음운을 연구할 수 있다. 그 연구 결과로 (1)濁聲母가 淸化되었으며 (2) 疑母가 소실되었다. (3) 捲舌音이 형성되기 시작했고 (4) -m운미가 -n운미로 합병되었다. (5) 入聲 운미가 소실되었다. 그러나 梅祖麟과 遠藤光曉가 『飜譯老乞大朴通事』의 諺文 주음과 성점을 텍스트로 중국어 성조에 대한 연구를 하여 調値를 재구했는데 특히 入聲에 대한 의견에서 차이를 보인다. 梅祖麟은 입성을 1개로 재구했고 遠藤光曉는 2가지로 재구하였다. 3.2 어법 虛詞에 대한 연구가 주로 진행되었다. 3.3 어휘 특수단어에 대한 考釋을 중심으로 연구를 진행했다. 4. 연구전망 4.1 자료의 발굴, 정리, 발간 4.2 한중협력 - 당시 韓國語 千涉의 유무에 관한 硏究, 韓中比較硏究

Influence of host plants on the development, survivorship, and fecundity of the summer fruit tortrix moth, Adoxophyes orana (Lepidoptera: Tortricidae)

Li Guang‐wei,Wang Hui‐min,Yang Wen‐tao,Chen Xiu‐lin,Li Bo‐liao,Chen Yu‐xin 한국곤충학회 2021 Entomological Research Vol.51 No.10

The summer fruit tortrix moth Adoxophyes orana is a seriously damaged leaf roller pest for fruit trees. In this study, we evaluated the effect of five host plants (apple, Malus domestica B.; peach, Prunus persica var. nectarina; apricot, Armeniaca vulgaris Lam.; mulberry, Morus alba L.; and jujube, Ziziphus jujuba M.) on the development, survival, and fecundity of A. orana under laboratory conditions. Results showed that the development times of A. orana on jujube were significantly longer than those on the other four plants. The preimaginal survival rate was influenced by the host plants, which were fed during the larval stage, and with the highest on peach, followed by apple, apricot, and mulberry, and with the lowest on jujube. Adult females from larvae reared on apricot laid the greatest numbers of eggs (318.11 eggs per female), while that on apple, jujube, and mulberry was smaller, and no significant difference was observed among them. The highest intrinsic rate of increase (rm) was observed on peach and apricot; these two fruit trees were considered to be the most suitable host plant for A. orana because of the shorter developmental duration, higher survival rate, and the highest fecundity.

Zheng Tan,Wei-hui Zhong,Bao Meng,Shi-chao Duan,Hong-chen Wang3,Xing-You Yao,Yu-hui Zheng 국제구조공학회 2023 Steel and Composite Structures, An International J Vol.47 No.2

The bearing capacities resisted by the two-bay beams of multi-story planar frames with unequal spans under column removal scenarios differ considerably owing to the asymmetric stress on the left and right beams connected to the failed column and cause the potential for beams with larger span-to-depth ratios to be unable to exert effectively, which is disadvantageous for resisting the vertical load in unequal-span frame structures. To address this problem, the structural measure of adding braces to the weak bays of multi-story unequal-span frames was proposed, with the objective of achieving a coordinated stress state in two-bay beams with unequal spans, thereby improving the collapse resistance of unequal-span frame structures. Before conducting the numerical simulation, the modeling methods were verified by previous experimental results of two multi-story planar frames with and without steel braces. Thereafter, the effects of the tensile and compressive braces on the collapse behavior of the frame structures were elucidated. Then, based on the mechanical action laws of the braces throughout the collapse process, a detailed design method for improving the collapse resistance of unequal-span frame structures was proposed. Finally, the proposed design method was verified by using sufficient example models, and the results demonstrated that the design method has good application prospects and high practical value.

Natural fracture prediction in Keshen 2 ultra-deep tight gas reservoir based on R/S analysis, Kuqa Depression, Tarim Basin

Hui Zhang,Wei Ju,Guoqing Yin,Xinyu Liu,Zhimin Wang,Sijia Liu,Ke Wang,Hui Yang,Ke Xu,Wenbo Luan 한국지질과학협의회 2021 Geosciences Journal Vol.25 No.4

Within ultra-deep tight sandstone gas reservoirs, natural fractures indicate significant effects on reservoir performance because they can serve as storage spaces for hydrocarbons and improve the permeability. Accurate prediction of natural fractures in ultra-deep reservoirs is critical to the exploration and development of tight gas in Keshen 2 Block of Kuqa Depression. In this study, several conventional logs are selected and the R/S analysis method is introduced to predict the development and distribution of natural fractures in ultra-deep tight sandstone reservoirs. Fracture development coefficient Q is calculated based on the second derivatives of lg(R/S) function and corresponding weight of each log parameter, which matches well with linear fracture density measured from image logs. There is a positive correlation between parameter Q and fracture density, higher Q values usually indicate larger fracture density. Factors causing mismatches between calculated parameter Q and fracture density are also analyzed. Fracture dip angle, fracture filling condition, vertical resolution of logs, multiple interpretations of conventional logs, and lateral detection difference between image and conventional logs may contribute to generate those false appearances. The results in this study are expected to provide new geological references for the exploration and development of ultra-deep tight gas in Keshen 2 Block of Kuqa Depression.

Evolutionary and functional implications of 3′ untranslated region length of mRNAs by comprehensive investigation among four taxonomically diverse metazoan species

Wei Wang,Dong‑hui Fang,Jia Gan,Yi Shi,Hui Tang,Huai Wang,Mao‑zhong Fu,Jun Yi 한국유전학회 2019 Genes & Genomics Vol.41 No.7

Background In eukaryotic organisms, it has been well acknowledged that 3′ untranslated regions (3′ UTRs) of mRNA are actively involved in post-transcriptional regulations of gene expression. Although both shortening and lengthening of 3′ UTRs of specific candidate genes were explicitly documented to have functional consequences, landscape of 3′ UTR lengths in relation to evolutionary dynamics and biological meanings remains to be elucidated when large-scale data become available. Objectives The primary objective of this study was to revealed different inter- and intra-species patterns on length distribution of 3′ UTRs in comparison with 5′ UTRs and coding regions. Methods In the present study, we investigated 3′ UTR lengths in a highly curated set of 57,135 mRNA sequences among four well-studied and taxonomically diverse metazoan species (fruit fly, zebrafish, mouse and human). Results The average length ratio of 3′–5′ UTRs considerably increased from fruit fly (twofold) to human (fivefold). Moreover, genes can be characterized by the obviously different patterns of evolutionary change on 3′ UTR lengths. By utilizing the Gene Ontology annotations, genes with differential lengths of 3′ UTRs were suggested to have the divergent functional implications. In human, we further revealed that ubiquitously transcribed genes had higher median lengths of 3′ UTRs than the genes of tissue-restricted expressions. Conclusion We conducted a comprehensive analysis and provided an overview regarding 3′ UTRs biology of mRNAs in animals, whereas the mechanistic explanations of 3′ UTRs length variation in correlation to regulation of gene expression still remain to be further studied.

Wang, Wei-Lan,Tang, Zhi-Hui,Xie, Ting-Ting,Xiao, Bing-Kun,Zhang, Xin-Yu,Guo, Dai-Hong,Wang, Dong-Xiao,Pei, Fei,Si, Hai-Yan,Zhu, Man Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.14

Background: Many clinical trials have been conducted to evaluate sorafenib for the treatment of advanced NSCLC, but the results for efficacy have been inconsistent. The aim of this study was to evaluate the efficacy and safety of sorafenib in patients with advanced NSCLC in more detail by meta-analysis. Methods: This meta-analysis of randomized controlled trials (RCTs) was performed after searching PubMed, EMBASE, ASCO Abstracts, ESMO Abstracts, and the proceedings of major conferences for relevant clinical trials. Two reviewers independently assessed the quality of the trials. Outcomes analysis were disease control rate (DCR), progression- free survival (PFS), overall survival (OS) with 95% confidence intervals (CI) and major toxicity. Subgroup analysis was conducted according to sorafenib monotherapy, in combination with chemotherapy or EGFR-TKI to investigate the preferred therapy strategy. Results: Results reported from 6 RCTs involving 2, 748 patients were included in the analysis. Compared to sorafenib-free group, SBT was not associated with higher DCR (RR 1.31 (0.96- 1.79), p=0.09), PFS (HR 0.82 (0.66-1.02), p=0.07) and OS (HR 1.01 (0.92-1.12), p=0.77). In terms of subgroup results, sorafenib monotherapy was associated with significant superior DCR and longer PFS, but failed to show advantage with regard to OS. Grade 3 or greater sorafenib-related adverse events included fatigue, hypertension, diarrhea, oral mucositis, rash and HFSR. Conclusions: SBT was revealed to yield no improvement in DCR, PFS and OS. However, sorafenib as monotherapy showed some activity in NSCLC. Further evaluation may be considered in subsets of patients who may benefit from this treatment. Sorafenib combined inhibition therapy should be limited unless the choice of platinum-doublet regimen, administration sequence or identification of predictive biomarkers are considered to receive better anti-tumor activity and prevention of resistance mechanisms.

Effects of Free Anthraquinones Extract from the Rhubarb on Cell Proliferation and Accumulation of Extracellular Matrix in High Glucose Cultured-Mesangial Cells

Wang, Jianyun,Fang, Hui,Dong, Bingzheng,Wang, Dongdong,Li, Yan,Chen, Xiao,Chen, Lijuan,Wei, Tong,Wei, Qunli The Korean Society of Pharmacology 2015 The Korean Journal of Physiology & Pharmacology Vol.19 No.6

Diabetic nephropathy (DN) is the leading cause of end-stage failure of the kidney, but the efficacy of currently available strategies for the prevention of DN remains unsatisfactory. In this study, we investigated the effects of free anthraquinones (FARs) extract, which was extracted from the rhubarb and purified by macroporous resin DM130 with gradient mixtures of ethanol/water as the lelution solvents, in high glucose-cultured glomerular mesangial cells (MCs). The cell proliferation was determined by CCK-8 assay, the levels of TGF-${\beta}1$, CTGF, ColIV and FN proteins in the supernatant of MCs were measured by ELISA assays, and the mRNA levels of these four genes were detected by RT-PCR. The results showed that the increased proliferation of MCs, the mRNA levels and protein expression of TGF-${\beta}1$, CTGF, ColIV and FN induced by high glucose were inhibited after the treatment with the FARs extract. This indicated that FARs extract could inhibit cell proliferation and the expression of main extracellular matrix induced by high glucose in MCs. The FARs extract exhibited potential values for prophylaxis and therapy of DN.

Wang, Hui,Wang, Jin,Yang, Dan-dan,Liu, Zong-li,Zeng, Yong-qing,Chen, Wei Asian Australasian Association of Animal Productio 2020 Animal Bioscience Vol.33 No.3

Objective: The objective of this study was to measure the special expression pattern of lipid metabolism genes and investigate the molecular mechanisms underlying intramuscular fat (IMF) deposition in Longissimus dorsi muscle of Laiwu pigs. Methods: Thirty-six pigs (Laiwu n = 18; Duroc×Landrace×Yorkshire n = 18) were used for the measurement of the backfat thickness, marbling score, IMF content, and expression of lipid metabolism genes. Results: Significant correlations were found between IMF content and the mRNA expression of lipid metabolism genes. Of the 14 fat deposition genes measured, fatty acid synthase (FASN) showed the strongest correlation (r = 0.75, p = 0.001) with IMF content, and of the 6 fat removal genes, carnitine palmitoyl transferase 1B (CPT1B) exhibited the greatest negative correlation (r = -0.66, p = 0.003) with IMF content in Laiwu pig. Multiple regression analysis showed that CPT1B, FASN, solute carrier family 27 member 1 (SLC27A1), and fatty acid binding protein 3 (FABP3) contributed 38% of the prediction value for IMF content in Laiwu pigs. Of these four variables, CPT1B had the greatest contribution to IMF content (14%) followed by FASN (11%), SLC27A1 (9%), and FABP3 (4%). Conclusion: Our results indicate that the combined effects of an upregulation in fat deposition genes and downregulation in fat removal genes promotes IMF deposition in Laiwu pigs.
