Real-Time Repairable Interpolation Scheme for CNC Tool Path Processing

Wei Fan,Chen-Han Lee,Ji-Hong Chen 한국정밀공학회 2016 International Journal of Precision Engineering and Vol.17 No.12

G01 trajectory is widely-adopted for CNC machining. The piecewise linear trajectory is geometrically discontinuous, bringing about drastic fluctuation of feedrate and acceleration, and causing low machining efficiency and quality. Many methods of trajectory smoothing are developed and applied in CNC system. However some shortcomings exist when these methods were applied in CNC machining. In the existing methods, the following requirements are not satisfied simultaneously: not less than G2 continuity, confined chord error, shape preservation, interpolating G01 points, spatial applicability, real-time performance of algorithm, free geometric form. Considering various requirements of CNC machining, this work develops an interpolation scheme with local repairing function to deal with the possible shape deficiencies of trajectory. The resulting tool path has G2 continuity and is optimized in bending energy under shape-preserving and chord error constraints. Combining with jerk-limited feedrate scheduling, a real-time tool path processing strategy is developed. The simulation demonstrates the proposed method eliminates shape deficiencies, and has apparent advantage in the reduction of contour error, curvature, bending energy and machining time, compared with Zhao’s and Fan’s methods. The experiment demonstrates the advantages of the proposed algorithm in improving the quality of machined surface and machining efficiency, compared with previous methods.

Fan, Qing-Ji,Kim, Won-Kyum The Korea Contents Association 2009 International Journal of Contents Vol.5 No.1

The purpose of this study is to investigate the impacts of e-service quality factors on customer satisfaction and behavior intention by Web site types. Difference and moderating effect resulting from the type of web site users about an association with reaction of satisfaction and those component concepts are also one of the aims in the study. As a result, the study found that factors of web site service quality variables had positive impacts on customer satisfaction. And customer satisfaction also had a positive impact on relationship intention and word of mouth intention. Furthermore, through the comparative analysis, we found that the service quality differed on the effects of customer satisfaction by web site types. According to those results, marketing managers should develop different service strategies based on different web site types.

Ji Fan 국제문화기술진흥원 2023 International Journal of Advanced Culture Technolo Vol.11 No.1

Chinese traditional patterns, which are part of our national precious heritage, have a long history. Tiger culture plays a very important role in folk art. In modern society, it is a symbol of human spirit and morality. The tiger pattern is also a unique traditional pattern in Chinese folklore. From the Spring and Autumn period to modern society, the tiger pattern has evolved in form through thousands of years of development. It is also a representative intangible cultural heritage in contemporary times. It plays a special role in the cultural exchange of different regions, resulting in the generation of the creation of folk art with great local characteristics. Therefore, traditional tiger patterns are an important part of traditional Chinese folk culture and art. In this study, by analyzing the development and evolution history of Chinese traditional tiger patterns, the application methods of Chinese traditional tiger patterns were summarized, the rich cultural connotation, artistic characteristics and application of traditional tiger pattern in modern fashion design were discussed. In contemporary design, the new and improved tiger pattern styles were explored, intangible cultural heritage was interpreted and inherited, and the cultural and artistic values contained therein were extracted. The author combined with modern fashion design, according to people's aesthetic taste and design principles, it is recreated,so that the traditional pattern has certain characteristics of The Times.But at the same time it retains its original character,and the traditional tiger pattern was inherited and the cultural connotation of clothing design was enriched.

Comparison of Microbial Diversity and Composition in the Jejunum and Colon of Alcohol-Dependent Rats

( Yang Fan ),( Zhao Ya-e ),( Wei Ji-dong ),( Lu Yu-fan ),( Zhang Ying ),( Sun Ya-lun ),( Ma Meng-yu ),( Zhang Rui-ling ) 한국미생물생명공학회(구 한국산업미생물학회) 2018 Journal of microbiology and biotechnology Vol.28 No.11

Alcohol dependence is a global public health problem, yet the mechanisms of alcohol dependence are incompletely understood. The traditional view has been that ethanol alters various neurotransmitters and their receptors in the brain and causes the addiction. However, an increasing amount of experimental evidence suggests that gut microbiota also influence brain functions via gut-to-brain interactions, and may therefore induce the development of alcohol use disorders. In this study, a rat model of alcohol dependence and withdrawal was employed, the gut microbiota composition was analyzed by high-throughput 16S rRNA gene sequencing, and the metagenome function was predicted by PICRUSt software. The results suggested that chronic alcohol consumption did not significantly alter the diversity and richness of gut microbiota in the jejunum and colon, but rather markedly changed the microbiota composition structure in the colon. The phyla Bacteroidetes and eight genera including Bacteroidales S24-7, Ruminococcaceae, Parabacteroides, Butyricimonas, et al were drastically increased, however the genus Lactobacillus and gauvreauii in the colon were significantly decreased in the alcohol dependence group compared with the withdrawal and control groups. The microbial functional prediction analysis revealed that the proportions of amino acid metabolism, polyketide sugar unit biosynthesis and peroxisome were significantly increased in the AD group. This study demonstrated that chronic alcohol consumption has a dramatic effect on the microbiota composition structure in the colon but few effects on the jejunum. Inducement of colonic microbiota dysbiosis due to alcohol abuse seems to be a factor of alcohol dependence, which suggests that modulating colonic microbiota composition might be a potentially new target for treating alcohol addiction.

소비자 적개심과 국가이미지가 제품평가에 미치는 영향: 중국과 러시아에 대한 비교연구

Qing Ji Fan,이정열 한국국제경영관리학회 2015 국제경영리뷰 Vol.19 No.3

본 연구의 주된 목적은 소비자 적개심과 국가이미지가 제품평가에 어떤 영향을 미치는지를 규명하고자 하는 것이다. 이를 위해 한국 소비자를 대상으로 실증분석을 실시하여 중국과 러시아 두 개 신흥시장국가 간에 나타나는 차이를 분석하였다. 실증분석 결과는 국가이미지의 두 가지 하위 차원인 인지적 국가이미지와 정서적 국가이미지를 도출하였고 소비자 적개심이 인지적 국가이미지와 정서적 국가이미지에 미치는 영향은 소비자 평가대상국(중국․러시아)에 따라 차이가 있다는 것을 밝혀냈다. 이러한 연구결과는 신흥시장국가의 국가이미지에 이론적 시사점을 제공할 뿐만 아니라 해외로 진출하려는 신흥시장국가의 다국적 기업에 전략적 시사점도 제공해 줄 수 있다. The main objective of this research is for us to empirically explore how consumer animosity and country image affect product evaluation. For this, we analyzed the difference between two emerging markets (i.e. China and Russia) by conducting empirical analyses on Korean consumers. As our empirical results, we acquired two sub-dimensions of country image - cognitive country image and affective country image - and confirmed that the impact of cognitive country image and affective country image has a difference according to consumers’ evaluation countries (i.e. China and Russia). Implications of these findings not only provide theoretical evidence to the study of consumer animosity and country image of emerging markets, but also draw an empirical evidence to the strategic management of Chinese and Russia multinational enterprises, who try to enter overseas countries.
