Ukiyo-e - Oriental Art that Has Been Influencing the World

Wu Xiaochen 국제문화기술진흥원 2023 International Journal of Advanced Culture Technolo Vol.11 No.3

Ukiyo-e, a pivotal facet of Japanese art, had a profound impact on Western art during the 19th century, contributing to the emergence of Impressionism and Post-Impressionism. Notably, Katsushika Hokusai's "Great Wave" remains an enduring masterpiece. Ukiyo-e's historical trajectory is intricately linked to the socio-cultural context of its time. Japan's early artistic influences derived from China, evolving through the Nara and Heian periods. Ukiyo-e emerged from the Yamato-e tradition, characterized by its transition from religious themes to secular subjects. Zen Buddhism's influence during the Muromachi Shogunate shifted focus to ink wash painting, which eventually became accessible to the masses. The Azuchi-Momoyama period introduced lavish, colorful works. The Edo Shogunate upheld Kano School for the elite, while folklore painting gained popularity among the commoners, leading to the creation of Ukiyo-e. Ukiyo-e diversified its subjects, including beauty, geisha, sumo, landscapes, and more. The Asakusa district's "Shin-Yoshiwara" added to its vibrant themes. By the late 19th century, Ukiyo-e transcended its roots, encompassing landscapes, wildlife, and beyond. I explore Ukiyo-e's aesthetics and its influence on Impressionism, focusing on "The Three Masters of Ukiyo-e" – Kiyotagawa Komaro, Katsushika Hokusai, and Utagawa Hiroshige.

Uniaxial tensile test integrated design considering mould-fixture for UHPC

Zhang, Xiaochen,Shen, Chao,Zhang, Xuesen,Wu, Xiangguo,Faqiang, Qiu,Mitobaba, Josue G. Techno-Press 2022 Advances in computational design Vol.7 No.4

Tensile property is one of the excellent properties of ultra-high performance concrete (UHPC), and uniaxial tensile test is an important and challenging mechanical performance test of UHPC. Traditional uniaxial tensile tests of concrete materials have inherent defects such as initial eccentricity, which often lead to cracks and failure in non-test zone, and affect the testing accuracy of tensile properties of materials. In this paper, an original integrated design scheme of mould and end fixture is proposed, which achieves seamless matching between the tension end of specimen and the test fixture, and minimizes the cumulative eccentricity caused by the difference in the matching between the tension end of specimen and the local stress concentration at the end. The stress analysis and optimization design are carried out by finite element method. The curve transition in the end of specimen is preferred compared to straight line transition. The rationality of the new integrated design is verified by uniaxial tensile test of strain hardening UHPC, in which the whole stress-strain curve was measured, including the elastic behavior before cracking,strain hardening behavior after cracking and strain softening behavior.

Jaeho Lee,Xiaochen Wu 한국국제경영관리학회 2014 국제경영리뷰 Vol.18 No.4

수출과 혁신의 관계를 다룬 문헌들 중 혁신이나 높은 생산성이 수출을 선행한다는 연구들이 있는 반면, 또다른 연구들은 수출이 혁신으로 이어진다고 주장하며, 또한 여러 실증분석에 따르면 수출을 하는 국가가 수출을 하지 않는 국가보다 더 높은 생산성을 지니고 여러 분야에서 더 좋은 성과를 거두고 있음을 보여주고 있다. 그렇지만 미시적 차원인 기업 측면에서 수출이 기업 혁신성을 향상시키는 실증적 증거는 드물다. 수출 기업은 국내 시장에서 얻지 못하는 다양한 지식을 획득할 수 있고 그러한 지식들이 본사로 유입되어 결국은 새로운 혁신 성과를 형성한다. 본 논문은 이러한 이론에 근거하여 KIS 2010 데이터를 활용하고 프로빗 회귀분석을 통하여 수출이 한국 제조업 기업의 제품 혁신, 공정 혁신, 조직 혁신 및 마케팅 혁신에 미치는 효과를 살펴보고자 한다. 실증분석 결과를 따르면 수출은 혁신에 긍정적 영향을 미친다. 특히 제품 혁신에 미치는 영향이 더 현저하다. 그리고 수출 집중도가 높을수록, 기업의 제품 혁신, 공정 혁신 및 조직 혁신 활동이 더 많이 전개된다. 그렇지만, 수출 집중도와 마케팅 혁신과의 관계에 대한 가설은 채택되지 못하였다. While a body of literature states that higher productivity or innovation leads firms to engage in exporting, previous empirical findings across many nations have also shown that exporting operation can precede productivity in the opposite direction and exporters perform better than non-exporters in several domains. We argue that exporters can often access diverse knowledge inputs not available in the domestic market, and this knowledge learning can spill back on the focal firm, thereby fostering increased innovation. In this paper, we examined the effects of exporting on the product, process, and organizational and marketing innovations of Korean manufacturing firms implementing probit regressions using the 2010 Korean Innovation Survey (KIS) data. We found that exporting is positively associated with innovation, especially product innovation. Moreover, the higher the level of exporting a manufacturing firm achieves, the more likely innovation activities are to be conducted in product, process, and organizational innovation areas. However, our data did not support our hypothesis regarding the relationship between export intensity and marketing innovation.

A hybrid artificial intelligence and IOT for investigation dynamic modeling of nano-system

Ren, Wei,Wu, Xiaochen,Cai, Rufeng Techno-Press 2022 Advances in nano research Vol.13 No.2

In the present study, a hybrid model of artificial neural network (ANN) and internet of things (IoT) is proposed to overcome the difficulties in deriving governing equations and numerical solutions of the dynamical behavior of the nano-systems. Nano-structures manifest size-dependent behavior in response to static and dynamic loadings. Nonlocal and length-scale parameters alongside with other geometrical, loading and material parameters are taken as input parameters of an ANN to observe the natural frequency and damping behavior of micro sensors made from nanocomposite material with piezoelectric layers. The behavior of a micro-beam is simulated using famous numerical methods in literature under base vibrations. The ANN was further trained to correlate the output vibrations to the base vibration. Afterwards, using IoT, the electrical potential conducted in the sensors are collected and converted to numerical data in an embedded mini-computer and transferred to a server for further calculations and decision by ANN. The ANN calculates the base vibration behavior with is crucial in mechanical systems. The speed and accuracy of the ANN in determining base excitation behavior are the strengths of this network which could be further employed by engineers and scientists.

Investigation of a Plasma-Etching Process That Uses a Porous Dielectric Template

Xiaoxia Zhong,Luqi Yuan,Xiaochen Wu,Qiwei Shu,Yuxing Xia 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.4

A plasma etching proces of GaN films that used a porous dielectric template was investigated by using numerical simulations. The electrical field, caused by both the substrate bias and the charges acumulated on the insulating template surface, was asumed to affect ions trajectories. Reactive ions enter the sheath with a velocity calculated by using a maxwelian distribution. We found that the microscopic electrical field over the template could change the ion movement. The substrate potential and the nanopore structure showed an ability to affect the etching rate. A peak value of the reactive etching species could be found on the lateral wal in the nanopores. Changing the parameters helped to weaken the peak and, hence, to make the etching proces more effective. The work reported here may help people to understand plasma etching using a porous alumina template.

Structural and Optical Properties of Titanium Oxide Thin Films Deposited on Unheated Substrate at Different Total Pressures by Reactive dc Magnetron Sputtering with a Substrate Bias

Wie Zhou,Xiaoxia Zhong,Luqi Yaun,Qiwei Shu,Xiaochen Wu,Yuxing Xia 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.49 No.5I

Titanium-oxide (TiO2) thin films were deposited on unheated (111)-Si substrates by reactive dc magnetron sputtering with a substrate bias voltage of .100 V. A pure metallic titanium target was sputtered in a mixture of argon and oxygen. The structure and the optical properties of the deposited films were studied by changing the value of the total sputtering pressure. X-ray diffraction patterns show the following features: (a) only one wide rutile (110) diffraction peak was observed at a total sputtering pressure of 0.3 Pa; (b) no diffraction peak was observed at 1.2 Pa, implying an amorphous phase; (c) a TiO2 film with a pure anatase phase was obtained at 3.6 Pa, and the dominant diffraction was from the anatase (101) planes. The surface morphology was characterized with atomic force microscopy, and the roughness of the surface was found to increase with the crystal size derived from the XRD data. The optical constants were determined by using spectroscopic ellipsometry. The film deposited at 0.3 Pa, a rutile phase, possessed both a high refractive index and a low extinction coefficient. The value of the optical bandgap for the deposited on films in this experiment was much higher than the reported experimental and theoretical values.D
