This study began with the recognition that focus on the experiences of the Chinese leaners and study the process of reading and understanding poetry using their experiences is necessary. By selecting Chinese leaners and ethnic-Korean learners in China as research subjects, we will also examine the personal and cultural differences of the subjects of experience and the effect of differences in identity recognition on reading. Through these efforts, we intends to design a method of teaching and learning modern Korean poetry that can arise self-awareness, understand others, and develop communication skills, which beyond a conceptual understanding of poetry text. Literature allows for multilayered and abundant language learning, beyond the limits of simple and repetitive mechanical language learning. Literature is sometimes referred to as ‘expression of thought’ or ‘expression of valuable experience’. This means that ideas and emotions are derived from concrete experiences, and that everything is not literature, but only when it is meaningful to human being. Among literature, poetry is a subjective genre, which presents images of oneself in a direct relationship to ‘self’ and emphasizes experience and emotion. However, Korean literature education in China has focused only on understanding and analyzing the experiences of writers which depicted in their works, and has not paid much attention to the experiences of learners who accepting the literature. The learner’s experience can be influenced by nationality, the environment he or she has grown, the educational experience, etc., and the diversity of his or her experiences means the diversity of reading. Therefore, this study, tries to understand how the learner’s experience is related to literature work and how that experience has an effect on reading poetry. In order to identify the reading patterns in the actual learner, and to come up with an educational method suitable for the process of such thinking and expression, this study analyzed the questionnaires and interview materials produced by the actual learner. In addition, through related theories, we explored the concepts of experience in poetry reading, and set the principles of modern Korean poetry reading in three categories: reading through learning experience, reading through social and cultural backgrounds, and reading through learner identity recognition. Based on this, we looked at the aspects of Chinese learners’ experiences in modern Korean poetry reading as follows: First, the ‘effect of learning experience of learner’ was divided into ‘effect of learning experience in understanding text’ and ‘effect of learning experience in interpretation’. Second, the ‘effect of learner’s social and cultural background’ was divided into ‘effect of social and cultural background in intertextual evocation’ and ‘effect of social and cultural background in making relationships with text.’ Third, we divided the ‘effect of learner identity recognition’ into ‘effect of identity in self-discovery’ and ‘effect of identity in the discovery of a heterogeneous world.’ Along with these aspects, we looked at the factors that influenced reading poetry in each aspect. Based on the actual data of the learners, this study confirmed various aspects of poetry reading and tried to present appropriate education methods by collecting the learners’ responses. In addition, our work has significance in working with Chinese learners and ethnic-Korean learners in China, we looked at how the diversity of experiences derived from personal differences, social and cultural differences, and identity differences can be revealed in modern Korean poetry reading.

Global Output Feedback Stabilization Control for Nonlinear Systems without Backstepping

Xiao Yan,Hongzheng Quan,Fujin Jia 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.6

In this paper, we study the global output feedback stabilization (GOFS) of nonlinear systems with unknown functions (UFs). Firstly, a lemma is introduced to solve UFs, which avoids the shortcomings of the approximate algorithms. At the same time, this lemma avoids the assumptions of UFs, thus reducing the conservatism of the algorithms. Secondly, based on Lyapunov function analysis, the controller is designed, which solves the GOFS problem of the controlled system. This control algorithm adopts nonbackstepping, so it avoids the complicated calculation of backstepping. Finally, the control algorithm is applied to the Duffing system to verify its effectiveness.

한·중 근대 편지 쓰기 교육에 대한 고찰 -한·중 편지 쓰기 교재 분석을 중심으로-

김소연 ( Jin¸ Xiao-yan ) 청람어문교육학회 2021 청람어문교육 Vol.- No.83

본 연구는 한국과 중국의 근대 문식 환경의 변화에 주목하고, 한ㆍ중 근대 편지 쓰기 교육에 대해 고찰하고자 한다. 근대에 들어 우편제도가 발달함에 따라 사람들은 우표만 붙이면 언제든지 편지를 쓸 수 있었고, 편지를 쓰는 것이 하나의 유행으로 자리 잡게 되었다. 따라서 근대인들은 자연스럽게 편지는 어떻게 쓰는 것인지, 어떻게 하면 편지를 잘 쓸 수 있는지에 대해 관심을 갖게 되었으며, 다양한 편지 쓰기 교재가 출현하였다. 또한 편지는 근대 초기 글쓰기 교육의 중요한 교육내용이었다. 이러한 변화에 주목하여 본 연구는 20세기 이후 한국과 중국의 근대적 편지 쓰기 방식은 어떠했는지, 양국의 편지 쓰기 교육이 어떻게 이루어졌으며, 어떤 공통점과 차이점을 가지는지에 대해 고찰하고자 하였다. 이를 위해 한국과 중국의 편지 역사와 편지 교재에 대해 살펴보았고, 근대적 글쓰기로서의 편지 쓰기의 성격에 대해 검토하였으며, 한국과 중국의 공교육과 민간에서 이루어진 편지 쓰기 교육의 구체적 양상을 살펴보았다. 본 연구는 그동안 논의가 적었던 근대 편지 쓰기 교육에 주목하고 한국과 중국에서 편지 쓰기 교육이 어떻게 이루어졌는지, 어떤 특징을 가지는지 살펴 보았다는 점에서 의의를 지닌다. This study focuses on the changes in the modern literacy environment of Korea and China, and considers the education of modern letter writing in Korea and China. With the development of the postal system in modern times, people could write letters at any time by attaching stamps, and writing letters became a trend. Therefore, modern people naturally became interested in how to write letters and how to write letters well, and various letter-writing textbooks appeared. The letter was an important educational text in early modern writing education. Noting these changes, this study sought to examine how modern letter writing methods in Korea and China have been since the 20th century, how letter writing education between the two countries has been conducted, and what commonalities and differences they have. To this end, we examined the history of letters in Korea and China, the nature of letter writing as a modern writing, and the specific aspects of letter writing education in Korea and China. This study is significant in that it paid attention to modern letter writing education, which has been discussed less so far, and looked at how letter writing education was conducted in Korea and China and what characteristics it has.

한국 문학교육에서 문학 문식성과 자국어 교육 경험 간의 관계에 대한 고찰 - 중국인 학습자의 한국 현대시 의미 구성 양상을 중심으로 -

김소연 ( Jin¸ Xiao-yan ) 한국문학교육학회 2021 문학교육학 Vol.- No.73

과학기술의 발전이 언어의 도구적 역할을 대체하고 있는 상황에서 중국인 학습자를 위한 한국어교육은 기능적 문식성 교육을 넘어설 필요가 있다. 이러한 맥락에서 이 연구는 중국인 학습자를 위한 한국 문학교육의 지향을 문학문식성과 연관지어 살펴보았다. 중국인 학습자는 경험이 축적된 상태에서 한국 문학을 접하기 때문에 학습자의 다양한 선경험이 한국 문학 이해와 감상에 영향을 미친다. 이 연구는 중국인 학습자의 자국어 교육 경험에 주목하였다. 한국 문학교육에서의 문학 문식성은 문식 활동 주체의 특수성을 충분히 반영하면서 논의되어야 한다. 이에 한국어교육의 관점에서 문학 문식성의 개념을 검토하고, 한국 문학 문식성과 중국인 학습자의 자국어 교육 경험 간의 관계를 설명하였다. 다양한 질적 자료를 통해 중국인 학습자의 자국어 교육 경험이 한국 문학교육에서 어떤 영향을 미치는지 살펴보았는데, 중국인 학습자의 한국 현대시 의미 구성 양상을 ‘지식의 활용에서 자국어 교육 경험의 영향’, ‘경험의 환기에서 자국어 교육 경험의 영향’, ‘태도 형성에서 자국어 교육 경험의 영향’으로 나누어 제시하였다. In a situation where the development of science and technology is replacing the instrumental role of language, Korean language education for Chinese learners needs to go beyond functional literacy education. In this context, this study examined the orientation of Korean literature education for Chinese learners in connection with literary literacy. Since Chinese learners encounter Korean literature while accumulating experience, various prior experiences of learners influence their understanding and appreciation of Korean literature. This study focused on the experience of Chinese learners in their own language education, and explored how learners’ experience in their own language education relates to Korean literature literacy. Literary literacy in Korean literature education should be discussed while fully reflecting the specificity of the subject of literary activities. Therefore, the concept of literary literacy from the perspective of Korean language education was examined, the relationship between Korean literature literacy and Chinese learners’ domestic language education experience was explained, and various qualitative data were examined.

Xiaoyan Wang,Baochen Jiang,Chengyou Wang,Zhiqiang Yang,Xiaoyan Wang 보안공학연구지원센터 2014 International Journal of Signal Processing, Image Vol.7 No.5

With the development of the theory of wavelet transform, biorthogonal wavelet filter banks with linear phase and compact support characteristics are widely used in signal and image processing. We study the multiscale edge detection using anti-symmetrical biorthogonal wavelet filter banks with the same even length based on the analysis of the properties of this wavelet filter banks. The steps of multiscale edge detection based on anti-symmetrical biorthogonal wavelet are introduced in detail. Experimental results on test images show that compared with the anti-symmetrical biorthogonal wavelet, the proposed anti-symmetrical biorthogonal wavelet filter banks with the same even length have better performance in terms of image edge detection. Therefore, the anti-symmetrical biorthogonal wavelet filter banks with the same even length are more suitable for image edge detection.

Xiaoyan Yang,Jinxin Gong,Bohan Xu,Jichao Zhu 사단법인 한국계산역학회 2017 Computers and Concrete, An International Journal Vol.19 No.6

This paper presents the two-, three-, and four-lane transverse reduction factor based on FEA method, probability theory, and the recently actual traffic flow data. A total of 72 composite girder bridges with various spans, number of lanes, loading mode, and bridge type are analyzed with time-varying static load FEA method by ANSYS, and the probability models of vehicle load effects at arbitrary-time point are developed. Based on these probability models, in accordance to the principle of the same exceeding probability, the multi-lane transverse reduction factor of these composite girder bridges and the relationship between the multi-lane transverse reduction factor and the span of bridge are determined. Finally, the multi-lane transverse reduction factor obtained is compared with those from AASHTO LRFD, BS5400, JTG D60 or Eurocode. The results show that the vehicle load effect at arbitrary-time point follows lognormal distribution. The two-, three-, and four-lane transverse reduction factors calculated by using FEA method and probability respectively range between 0.781 and 1.027, 0.616 and 0.795, 0.468 and 0.645. Furthermore, a correlation between the FEA and AASHTO LRFD, BS5400, JTG D60 or Eurocode transverse reduction factors is made for composite girder bridges. For the two-, three-, and four-lane bridge cases, the Eurocode code underestimated the FEA transverse reduction factors by 27%, 25% and 13%, respectively. This underestimation is more pronounced in short-span bridges. The AASHTO LRFD, BS5400 and JTG D60 codes overestimated the FEA transverse reduction factors. The FEA results highlight the importance of considering span length in determining the multi-lane transverse reduction factors when designing two-lane or more composite girder bridges. This paper will assist bridge engineers in quantifying the adjustment factors used in analyzing and designing multi-lane composite girder bridges.

Study on pharmacokinetics and tissue distribution of single dose oral tryptanthrin in Kunming mice by validated reversed-phase high-performance liquid chromatography with ultraviolet detection

Xiaoyan Zhang,Jie Xia,Wenjing Zhang,Yao Luo,Wenbo Sun,Wei Zhou 한국한의학연구원 2017 Integrative Medicine Research Vol.6 No.3

Background: Tryptanthrin is a major active constituent of several Chinese herbal plants, such as Isatidis radix. Tryptanthrin had been demonstrated to have several beneficial pharmacological effects in vitro for human diseases, including antitumor, anti-inflammatory and antibacteria activities. In contrast to the extensive in vitro investigations, the in vivo disposition process of tryptanthrin was explored limitedly. Methods: In this study, the pharmacokinetics (PK) and tissue distribution of tryptanthrin in Kunming mice following a single oral dose of 80 mg/kg tryptanthrin were investigated for the first time. Mouse plasma, liver, heart, spleen, lung, kidney and brain were collected and analyzed using a validated reversed-phase high-performance liquid chromatography with ultraviolet detection (RP-HPLC–UV) method after biological sample preparation by a simple liquid–liquid extraction. Results: The chromatographic analysis was performed on a Diamonsil C18 column (5 μm, 250 mm × 4.6 mm) and ultraviolet detection was set at a wavelength of 251 nm. The analysis was achieved with a mobile phase of methanol (A) and water (B) (60:40, v/v) at a flow rate of 1.0 mL/min. The method was linear over the concentration range of 4.0–400.0 μg/mL with a lower limit of quantification of 0.10–0.30 μg/mL. Inter- and intraday precisions (relative standard deviations %) were all within 2.93%. Recoveries of tryptanthrin were more than 86.44%. Maximal tryptanthrin concentrations in plasma and tissues of mice were reached within 2.5 hours. The actual highest concentration (Cmax) in mouse plasma was 3.13 μg/mL, the area under the curve (AUC0–t) was 9.38 h μg/mL, and the terminal half-life was 2.27 hours. The volume of distribution was 343.89 mL, the clearance rate was 204.58 mL/h, and the PK of tryptanthrin in mice after oral administration was fit to 2 compartment 1 st Order. After oral dosing of tryptanthrin to Kunming mice, the analyte was well distributed to the plasma and main tissues. Cmax was found in the liver with a mean value of 3.54 μg/g, followed by that in the kidney, lung, spleen, heart, and brain. Conclusion: In this study, a validated RP-HPLC–UV method was developed and successfully applied to PK and tissue distribution of oral tryptanthrin in mice. We confirmed that tryptanthrin was closely related and targeted to plasma, liver, kidney, and lung. These results indicate that tryptanthrin will have a good clinical application in the liver, kidney, or lung. The clinical use of tryptanthrin should focus on its pharmacodynamics and safety study in these tissues.

Novel Nucleotide Variations, Haplotypes Structure and Associations with Growth Related Traits of Goat AT Motif-Binding Factor (ATBF1) Gene

Xiaoyan Zhang,Xianfeng Wu,Wenchao Jia,Chuanying Pan,Xiangcheng Li,Chuzhao Lei,Hong Chen,Xianyong Lan 아세아·태평양축산학회 2015 Animal Bioscience Vol.28 No.10

The AT motif-binding factor (ATBF1) not only interacts with protein inhibitor of activated signal transducer and activator of transcription 3 (STAT3) (PIAS3) to suppress STAT3 signaling regulating embryo early development and cell differentiation, but is required for early activation of the pituitary specific transcription factor 1 (Pit1) gene (also known as POU1F1) critically affecting mammalian growth and development. The goal of this study was to detect novel nucleotide variations and haplotypes structure of the ATBF1 gene, as well as to test their associations with growth-related traits in goats. Herein, a total of seven novel single nucleotide polymorphisms (SNPs) (SNP 1-7) within this gene were found in two well-known Chinese native goat breeds. Haplotypes structure analysis demonstrated that there were four haplotypes in Hainan black goat while seventeen haplotypes in Xinong Saanen dairy goat, and both breeds only shared one haplotype (hap1). Association testing revealed that the SNP2, SNP5, SNP6, and SNP7 loci were also found to significantly associate with growth-related traits in goats, respectively. Moreover, one diplotype in Xinong Saanen dairy goats significantly linked to growth related traits. These preliminary findings not only would extend the spectrum of genetic variations of the goat ATBF1 gene, but also would contribute to implementing marker-assisted selection in genetics and breeding in goats.

Effect of Precipitate State on Mechanical Properties, Corrosion Behavior, and Microstructures of Al–Zn–Mg–Cu Alloy

Xiaoyan Peng,Yao Li,Guofu Xu,Jiwu Huang,Zhimin Yin 대한금속·재료학회 2018 METALS AND MATERIALS International Vol.24 No.5

The mechanical properties, corrosion behavior and microstructures of the Al–Zn–Mg–Cu alloy under various ageing treatmentswere investigated comparatively. The results show that the tensile strength and corrosion resistance are stronglyaff ected by the precipitate state. Massive fi ne intragranular precipitates contribute to high strength. Discontinuous coarsegrain boundary precipitates containing high Cu content, as well as the narrow precipitate free zone, result in low corrosionsusceptibility. After the non-isothermal ageing (NIA) treatment, the tensile strength of 577 MPa is equivalent to that of579 MPa for the T6 temper. Meanwhile, the stress corrosion susceptibility r tf and the maximum corrosion depth are 97.8%and 23.5 μm, which are comparable to those of 92.8% and 26.7 μm for the T73 temper. Moreover, the total ageing timeof the NIA treatment is only 7.25 h, which is much less than that of 48.67 h for the retrogression and re-ageing condition.

Model-based Compensation and Pareto-optimal Trajectory Modification Method for Robotic Applications

Xiaoyan Chen,Qiuju Zhang,Yilin Sun 한국정밀공학회 2019 International Journal of Precision Engineering and Vol.20 No.7

This study addresses the problem in accuracies of robot positioning and trajectory with compliance and geometric errors in robotic applications. A rigid–flexible coupling position error model of serial robot is presented to identify geometric and compliance error parameters simultaneously. On the basis of the error compensation model, the predicted position error can be corrected by the proposed hybrid error compensation method. Particular attention is paid to the deviation along the desired trajectory with respect to the corresponding updated trajectory, which is consecutively changing and cannot be corrected directly. A segmentation trajectory control method based on the Pareto-optimal with weighted-sum algorithm is proposed to solve the multi-objective optimisation problem in trajectory modification. The offline program optimiser integrates the proposed model-based compensation and trajectory modification method by MATLAB and VS software development platform. The method is developed to be an effective solution for the problem in absolute accuracies of positioning and trajectory with the experimental results achieved on a Staubli TX60L robot. Additional experiment is conducted with a Staubli RX160L robot to demonstrate the extensive feasibility and practical effectiveness of our approach for other industrial robots.
