In this study, I have attempted to present the teaching method of Chinese Language in the everyday environment, that would enable Korean university students to loam Chinese in a simple, direct, and accurate manner within the shortest possible time. The Korean people live in a culture greatly influenced by Chinese culture and Chinese language throughout its history and accordingly, they can team Chinese language much easier than those living in other parts of the world. Particularly, their ability to read Chinese is exceptionally good. Despite the fact that most Chinese words used in two countries are the same, some words are used differently creating confusion between the two. Accordingly, for the best results, the Chinese Language should be taught with the following points in mind. First, special emphasis should be given to Chinese characters that are used differently in each country even though they are written the same way. Therefore, comparative teaching is recommended Secondly, Chinese characters that have the same meanings but pronounced differently between the two should be taught in a comparative manner as well. Thirdly, those learning Chinese language should also team about Chinese culture for a more comprehensive and in-depth understanding. Lastly, many new words created everyday as China goes through a drastic social change after the opening of the country must be taught in the actually applied situations so that the students loaming these words can understand the changing Chinese society better. The teachers of Chinese Language should consider the above points or more effective teaching. It will also give students a better understanding of Chinese society and culture.

Jiang, Jun,Quan, Xun-Feng,Zhang, Li,Wang, Yi-Chun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.5

Background: Findings from previous published studies regarding the association of the XRCC3 Thr241Met polymorphism with glioma susceptibility have often been conflicting. Therefore, a meta-analysis including all available publications was carried out to make a more precise estimation of the potential relationship. Methods: By searching the electronic databases of Pubmed and Embase (up to April 1st, 2013), a total of nine case-control studies with 3,752 cases and 4,849 controls could be identified for inclusion in the current meta-analysis. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of the association. Results: This meta-analysis showed the XRCC3 Thr241Met polymorphism to be significantly associated with decreased glioma risk in the allelic model (Met allele vs. Thr allele: OR= 0.708, 95%CI= 0.631-0.795). Moreover, we also observed a statistically significant association between the XRCC3 Thr241Met polymorphism and reduced glioma risk in analyses stratified by ethnicity (Asian) and source of controls (hospital based) in the allelic model. Conclusions: Current evidence suggests that the XRCC3 Thr241Met polymorphism may be a risk factor for glioma development, especially in Asians.

Influence of the Electrolytic Dy-Cu alloy on the Coercivity of Sintered Nd-Fe-B Magnet

Chun-fa Liao,Xun Zhou,Peng Jiang,Zhiyong Zeng,Lianghua Que 한국자기학회 2022 Journal of Magnetics Vol.27 No.4

The fluorine salt oxide molten-salt electrolytic Dy-Cu alloy was used as a grain boundary diffusion source instead of the doped Dy-Cu alloy. The microstructure and coercivity of the GBDPed magnets with the different diffusion times were studied. The results show that the coercivity increased with the increase in the GBDP time. The ability of the electrolytic Dy-Cu alloy to improve the coercivity of Nd-Fe-B is more advantageous than that of the doped Dy-Cu alloy. Microstructure analysis shows that the segregation and metal inclusion, a small amount of Dy2O3, and the poor synergy diffusion between Dy and Cu lead to the unsatisfactory performance of the doped Dy-Cu alloy to improve the coercivity. The diffusion rate and depth of the GBD source improved by replacing the doped alloy with an electrolytic alloy.

Tazarotene-Induced Gene 1 Interacts with DNAJC8 and Regulates Glycolysis in Cervical Cancer Cells

Chun-Hua Wang,Rong-Yaun Shyu,Chang-Chieh Wu,Mao-Liang Chen,Ming-Cheng Lee,Yi-Yin Lin,Lu-Kai Wang,Shun-Yuan Jiang,Fu-Ming Tsai 한국분자세포생물학회 2018 Molecules and cells Vol.41 No.6

The tazarotene-induced gene 1 (TIG1) protein is a retinoid-inducible growth regulator and is considered a tumor suppressor. Here, we show that DnaJ heat shock protein family member C8 (DNAJC8) is a TIG1 target that regulates glycolysis. Ectopic DNAJC8 expression induced the translocation of pyruvate kinase M2 (PKM2) into the nucleus, subsequently inducing glucose transporter 1 (GLUT1) expression to promote glucose uptake. Silencing either DNAJC8 or PKM2 alleviated the upregulation of GLUT1 expression and glucose uptake induced by ectopic DNAJC8 expression. TIG1 interacted with DNAJC8 in the cytosol, and this interaction completely blocked DNAJC8-mediated PKM2 translocation and inhibited glucose uptake. Furthermore, increased glycose uptake was observed in cells in which TIG1 was silenced. In conclusion, TIG1 acts as a pivotal repressor of DNAJC8 to enhance glucose uptake by partially regulating PKM2 translocation.

Synthesis of porous hollow silica spheres using functionalized polystyrene latex spheres as templates

Chun Liu,Hengbo Yin,Chen Ge,Aili Wang,Min Ren,Yunsheng Zhang,Longbao Yu,Tingshun Jiang 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.6

Uniform sized and integrated hollow silica spheres with porous shells were prepared by using sulfuric and carboxylic acid-functionalized polystyrene latex spheres as templates, sodium silicate as a precursor, and cetyltrimethylammonium bromide as a shell structure-directing agent. When polystyrene-methyl acrylic acid latex spheres were used as the templates, the pores in the shells of the resultant hollow silica spheres were composed of both micropores and mesopores. The pores in the shells of the hollow silica spheres were mainly composed of mesopores when sulfonated polystyrene-methyl acrylic acid latex spheres were used as the templates. The shell thickness and the specific surface area of the hollow silica spheres increased with the increase in the surface acidity of the latex spheres.

Process Improvements for Low-Defect CMOS Gate Oxide

Jiang, Chun,Mitchell, Todd,Kroonblawd, Loren,Nguyen, Duc,Lew, Eugene,Hu, Chenming, 대한전자공학회 1993 ICVC : International Conference on VLSI and CAD Vol.3 No.1

N^- well drive-in in oxygen ambient is found to induce stacking faults, which have a deleterious effect on the N^- well MOS gate oxide breakdown characteristics. This effect can be eliminated by using N^- well drive-in with nitrogen anneal. A wet gate oxide process is fund to give better gate oxide integrity than dry gate oxide and a comparable hot carrier robustness. The us of N^- well drive-in with nitrogen anneal and wet oxide processes, has drastically reduced oxide defect densities in both P^- substrate and N^- well MOS devices.

Down-regulation of Protease-activated Receptor 4 in Lung Adenocarcinoma is Associated with a More Aggressive Phenotype

Jiang, Ping,Yu, Guo-Yu,Zhang, Yong,Xiang, Yang,Hua, Hai-Rong,Bian, Li,Wang, Chun-Yan,Lee, Wen-Hui,Zhang, Yun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

The role of protease-activated receptors (PARs) in lung tumors is controversial. Although PAR4 is preferentially expressed in human lung tissues, its possible significance in lung cancer has not been defined. The studies reported herein used a combination of clinical observations and molecular methods. Surgically resected lung adenocarcinomas and associated adjacent normal lung tissues were collected and BEAS-2B and NCI-H157 cell lines were grown in tissue culture. PAR4 expression was evaluated by RT-PCR, RT-qPCR, Western blotting and immunohistochemistry analysis. The results showed that PAR4 mRNA expression was generally decreased in lung adenocarcinoma tissues as compared with matched noncancerous tissues (67.7%) and was associated with poor differentiation (p=0.017) and metastasis (p=0.04). Western blotting and immunohistochemical analysis also showed that PAR4 protein levels were mostly decreased in lung adenocarcinoma tissues (61.3%), and were also associated with poor differentiation (p=0.035) and clinical stage (p=0.027). Moreover, PAR4 expression was decreased in NCI-H157 cells as compared with BEAS-2B cells. In conclusion, PAR4 expression is significantly decreased in lung adenocarcinoma, and down-regulation of PAR4 is associated with a more clinically aggressive phenotype. PAR4 may acts as a tumor suppressor in lung adenocarcinoma.

Preservation of Simmental bull sperm at 0°C in Tris dilution: effect of dilution ratio and long-distance transport

Jiang Shouqing,Huang Fei,Niu Peng,Wang Jieru,He Xiaoxia,Han Chun-mei,Gao Qinghua 아세아·태평양축산학회 2024 Animal Bioscience Vol.37 No.2

Objective: This study aimed to assess the impact of the dilution ratio of Tris diluent, storage at 0°C, and long-distance transportation on the spermatozoa of Simmental cattle. It also validated the feasibility of the regional distribution of fresh semen. Methods: In experiment 1, semen was diluted at four dilution ratios (1:6, 1:9, 1:12, and 1:15) to determine the optimal dilution ratio of Tris diluent. In experiment 2, we assessed sperm viability, progressive motility (objectively assessed by computer-assisted sperm analyzer), and acrosome intactness in Tris dilutions kept at constant 0°C for 1, 3, 6, 9, and 12 days. We compared them to Tianshan livestock dilutions (Commercial diluent). In experiment 3, semen was diluted using Tris diluent, and sperm quality was measured before and after long-distance transport. Artificial insemination of 177 Simmental heifers compared to 156 using Tianshan Livestock dilution. Results: The outcomes demonstrated that 1:9 was the ideal Tris diluent dilution ratio. The sperm viability, Progressive Motility, and acrosome integrity of both Tris and Tianshan dilutions preserved at 0°C gradually decreased over time. sperm viability was above 50% for both dilutions on d 9, with a flat rate of decline. The decrease in acrosome integrity rate was faster for Tianshan livestock dilutions than for Tris dilutions when stored at 0°C for 1 to 6 days. There was no significant difference (p>0.05) in sperm viability between semen preserved in Tris diluent after long-distance transportation and semen preserved in resting condition. The conception rates for Tris dilution and Tianshan livestock dilution were 49.15% and 46.15% respectively, with no significant difference (p>0.05). Conclusion: This shows that Tris diluent is a good long-term protectant. It has been observed that fresh semen can be successfully preserved for long-distance transport when stored under 0°C conditions. Additionally, it is feasible to distribute semen regionally.

혈관내 봉한관을 관찰하는 방법을 개발하였다. 10% 포도당액을 대퇴정맥에 주입하여 봉한관을 굵고 강하게 만듦으로써, 혈관 절개후 쉽게 관찰할 수 있게 한 것이 핵심 기법이다. 봉한이론과 일치한 결과를 보였다. 봉한관은 반투명의 부드럽고 탄력 있는 실과 같으며, $10{\mu}m$ 정도의 작은 관의 다발로 구성되어 있다. A method for observing intra blood vessel ducts which are threadlike bundle of tubules which form a part of the BongHan duct system. By injecting 10% dextrose solution at a vena femoralis one makes the intravascular BongHan duct thicker and stronger to be easily detectable after incision of vessels. The duct is semi-transparent, soft and elastic, and composed of smaller tubules whose diameters are of $10{\mu}m$ order, which is in agreement with BongHan theory.
