Xiao‑Yu Zhao,Xian‑Ming Zhao,Chun‑Yu Dong,Yang Yang,Huai‑Bin Han 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.6

The variation of the morphology and distribution of cementite particles in different prior structures with spheroidizingannealing process has been proceeded in this paper. It is found that the dissolution and coarsening progresses of variousinitial structures in spheroidizing annealing process are quite asynchronous due to the different interlamellar spacing. Thedissolution rate of degenerated pearlite (D-P) with finer interlamellar spacing is faster. The granular cementite in the spheroidizedmicrostructure is fine, uniform and dense. The mean diameter of spherical cementite is refined to 233 nm. However,the initial structure of degenerated pearlite (D-P) is highly sensitive to the austenitization temperature. The cementite iseasy to be coarsened under high austenitizing temperature. The coarsening is accompanied by the gradual increase of theCr content in the cementite, which increases the stability of the cementite. Therefore, the optimal austenitizing temperaturefor degenerated pearlite (D-P) is suggested to be 770 °C.

중국은 유구한 역사를 지닌 주로 한족으로 구성된 다민족 국가이며, 한족은 전 세계 범위에서 인수가 가장 많은 민족이다. 영화 <영>은 2018년 중국에서 개봉되었고, 등장인물의 한족 복식이 수묵화의 형식으로 표현되어 중국의 전통문화와 복식의 상관관계를 잘 보여준다. 본 연구의 목적은 영화의 주요 등장인물 5명의 한족 복식을 형태, 색채, 문양을 중심으로 분석하고, 이들 복식에 나타난 수묵화의 표현특성을 분석하는 것이다. 연구 방법은 한족 복식, 중국 수묵화, 그리고 한족 복식에 대한 문헌연구를 하며, 연구 범위는 영화 속 등장인물 총 5명의 복식으로 하여 형태, 색채, 문양이 명확하게 표현된 25점의 이미지를 분석 대상으로 하였다. 본 연구의 결과는 다음과 같다. 첫째, 영화에 나타난 남자 인물의 복식은 전통 한족 복식과 일치하게 나타났으며, 여자 인물의 복식은 전통 한족 복식과 차이점이 있었다. 주요한 차이점은 여자 복식의 깃에 나타났으며, 영화에서는 전통복식에 없는 V령이 착용되어 여자 인물의 강직한 성격을 부각시켰다. 둘째, 영화의 한족 복식에 나타난 수목화의 표현특성은 추상미, 대조미, 의경의 내적 의미를 도출할 수 있었다. 추상미는 수묵화의 문양에서 나타났으며, 대조미는 색채 표현에서, 그리고 의경의 내적의미는 복식 형태와 문양에서 나타났다. 영화 영에서는 한족 복식의 형태, 색채, 문양을 통해 등장인물 개개인의 성격과 심리를 표현하였음을 알 수 있었으며, 수묵화를 활용한 복식디자인을 통해 중국의 전통미를 부각시켰다. 본 연구는 중국 전통 한족 복식 및 수묵화 특성의 이해를 높이고, 중국 전통문화와 복식 디자인 연구에 대한 참고자료가 될 수 있을 것으로 기대한다. China has a long history and is composed of multi-ethnic groups dominated by Han nationality. Since the Han nationality is known with the largest population in the world, the traditional culture of China has an important position in world cultures simultaneously. There was a film named < Shadow > released in China, 2018, which received authoritative awards in multiple fields including Visual effect, Fine art, Style design, and others. In this film, the characteristics of Chinese Ink Wash Painting can be seen in the pictures of all the lenses as well as characters’ costumes of Han nationality(Han Fu), that connected Chinese traditional cultures with the concept of Fashion design. Thence, we have analyzed on shape, color, and pattern of the Han Fu of five main characters and further discussed the performance characteristics of Chinese brush panting appearing in these costumes. The results of the analysis were shown below. Firstly, by comparison with historical records, we have found the costumes of male characters consistent with the real Chinese classical Han fu, while the situation of females is different. The main difference was from the collars, the V-collar element which does not exist in traditional female Han Fu was applied boldly in this film, which inspired the audiences to understand the role. Secondly, the performance characteristics of Chinese Ink Wash Painting in Han Fu were concentrated on the beauty of abstract and contrast, further reflect the inner meaning of artistic conception. The beauty of abstract and the inner meaning of artistic conception was shown from the pattern of Chinese Ink Wash Painting, while the situation of the beauty of contrast was from colors. This study will be helpful to understand the Chinese traditional Han Fu and Chinese brush painting through the film, and it may be utilized as sources for the connection between Chinese traditional culture and modern fashion design in the future.

Su, Li,Zhang, Yuan,Zhang, Chun-Yang,Zhang, An-Long,Mei, Xiao-Long,Zhao, Zhi-Jun,Han, Jian-Guo,Zhao, Li-Jun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3

We performed a case-control study to investigate whether SNPs of CHIP might affect the development of IA in Chinese Han nationality. We believe we are the first to have screened IA patients for mutations in the CHIP gene to determine the association with these variants. The study group comprised 224 Chinese Han nationality patients with at least one intracranial aneurysm and 238 unrelated healthy Han nationality controls. Genomic DNA was isolated from blood leukocytes. The entire coding regions of CHIP were genotyped by PCR amplification and DNA sequencing. Differences in genotype and allele frequencies between patients and controls were tested by the chi-square method. Genotype and allele frequencies of the SNP rs116166850 was demonstrated to be in Hardy-Weinberg equilibrium. No significant difference in genotype or allele frequencies between case and control groups was detected at the SNP. Our data do not support the hypothesis of a major role for the CHIP gene in IA development in the Chinese Han population.

Metabolic Module Mining Based on Independent Component Analysis in Arabidopsis thaliana

Xiao Han,김재연,Cong Chen,현태경,Ritesh Kumar 한국분자세포생물학회 2012 Molecules and cells Vol.34 No.3

Independent Component Analysis (ICA) has been intro-duced as one of the useful tools for gene-functional dis-covery in animals. However, this approach has been poorly utilized in the plant sciences. In the present study, we have exploited ICA combined with pathway enrichment analysis to address the statistical challenges associated with genome-wide analysis in plant system. To generate an Arabidopsis metabolic platform, we collected 4,373 Affy- metrix ATH1 microarray datasets. Out of the 3,232 metabolic genes and transcription factors, 99.47% of these genes were identified in at least one component, indicating the coverage of most of the metabolic pathways by the components. During the metabolic pathway enrichment analysis, we found components that indicate an independent regulation between the isoprenoid biosynthesis pathways. We also utilized this analysis tool to investigate some transcription factors involved in secondary cell wall bio-genesis. This approach has identified remarkably more transcription factors compared to previously reported analysis tools. A website providing user-friendly searching and downloading of the entire dataset analyzed by ICA is available at http://kimjy.gnu.ac.kr/ICA.files/slide0002.htm. ICA combined with pathway enrichment analysis might provide a powerful approach for the extraction of the components responsible for a biological process of interest in plant systems.

Han, Ye,Xue, Xiao-Feng,Shen, Hu-Gang,Guo, Xiao-Bo,Wang, Xu,Yuan, Bin,Guo, Xing-Po,Kuang, Yu-Ting,Zhi, Qiao-Ming,Zhao, Hong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.11

Objective: Beclin-1 has recently been observed as an essential marker of autophagy in several cancers. However, the prognostic role of Beclin-1 in colorectal neoplasia remains controversial. Our study aimed to evaluate the potential association between Beclin-1 expression and the outcome of colorectal cancer patients. Materials and Methods: All related studies were systematically searched in Pubmed, Embase, Springer and Chinese National Knowledge Infrastructure databases (CNKI), and then a meta-analysis was performed to determine the association of Beclin-1 expression with clinical outcomes. Finally, a total of 6 articles were included in our analysis. Results: Our data showed that high Beclin-1 expression in patients with CRC was associated with poor prognosis in terms of tumor distant metastasis (OR=2.090, 95%CI=1.061-4.119, p=0.033) and overall survival (RR=1.422, 95%CI=1.032-1.959, p=0.031). However, we did not found any correlation between Beclin-1 over-expression and tumor differentiation (OR=1.711, 95%CI=0.920-3.183, p=0.090). In addition, there was no evidence of publication bias as suggested by Egger's tests for tumor distant metastasis (p=1.000), differentiation (p=1.000) and OS (p=0.308). Conclusions: Our present meta-analysis indicated that elevated Beclin-1 expression iss associated with tumor metastasis and a poor prognosis in patients with CRC. Beclin-1 might serve as an efficient prognostic indicator in CRC, and could be a new molecular target in CRC therapy.

Mechanism using Taguchi-Based Differential Evolution Algorithm to Optimize the Bicycle Industry in China

Xiao Han Liu,Seng Fat Wong 대한산업공학회 2018 Industrial Engineeering & Management Systems Vol.17 No.1

Sustainable manufacturing considers that efficiently controlling the early stages of a manufacturing system is an important issue for industry enterprise. However, the data collected at this point is usually limited due to cost and time issues, making it difficult to realize the real situation in the production process. One of the ways to solve this problem is to use a small data build prediction system, such as the various grey methods. Although the grey forecasting model has been successfully adopted in various fields and demonstrated promising results, it can still be further improved. Meanwhile, Chinese bicycles have had a tremendous effect on society. This paper thus combines Chinese bicycle industry proposes a new way to improve forecasting accuracy. The new prediction model is called Rolling-TDEGM(1, 1). The grey model contributes to forecasting the future demand, and the TDE method is applied to optimize the parameters of grey model based on the minimization of forecasting error. Also, the rolling mechanism can keep the real-time data. In this experimental study, the public dataset and a real case are used to confirm the effectiveness of the proposed model; the experiment indicates that the Rolling-TDE-GM(1, 1) can significantly improve prediction precision.

Species diversity and distribution of the genus Colpomenia (Scytosiphonaceae, Phaeophyceae) along the coast of China

Xiao-Han Song,Zi-Min Hu,Zhong-Min Sun,Stefano G. A. Draisma,Pablo Fresia,De-Lin Duan 한국조류학회I 2019 ALGAE Vol.34 No.3

The marine brown algal genus Colpomenia has a worldwide distribution, with five species reported in Korea and Japan. However, no studies to date attempted to identify the number of species and geographical distribution of Colpomenia along Chinese coast. To fill the biodiversity knowledge gap, we analyzed 63 mitochondrial cox3 and 62 mitochondrial atp6 sequences of Colpomenia specimens collected from 30 localities along the Chinese coast. Maximum likelihood and Bayesian inference trees suggest the presence of at least three Colpomenia species (i.e., C. peregrina, C. claytoniae, and C. sinuosa) in China. C. peregrina and C. claytoniae are documented for the first time. C. sinuosa was only found in the South China Sea and its distribution didn’t overlap with that of C. peregrina which was found in the Yellow-Bohai Sea and the East China Sea. C. claytoniae appears to be confined to three isolated islands in the East and the South China Sea, where it occurs in sympatry with, respectively, C. peregrina and C. sinuosa. Future study can focus on comparing ecophysiological differences of Colpomenia species in response to environmental variables and exploring possible genetic hybridization / introgression at inter-specific contact zones.
