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.

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.

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.

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.

Improving the thermoelectric properties of carbon nanotubes through introducing graphene nanosprings

Xiaoyan Xu,Huaping Xiao,Tao Ouyang,Jianxin Zhong 한국물리학회 2020 Current Applied Physics Vol.20 No.1

Carbon nanotube (CNT) is a typical one-dimensional nanomaterial containing sp2 hybridization states. In this paper, we investigate the ballistic thermoelectric performance of CNTs incorporating graphene nanosprings by using non-equilibrium Green's function. The calculations reveal that the thermoelectric figure of merit could be obviously improved by introducing graphene nanosprings, which is about ten times of that of pristine CNTs at 700 K. Such enhancement is mainly attributed to the remarkable suppression of phononic and electronic thermal conductance and improvement of Seebeck coefficient. In addition, compared to the zigzag graphene nanospring, introducing of the armchair case possesses better thermoelectric performance. The results presented in this paper indicate that embedding graphene nanospring is a viable method to optimize the thermoelectric performance of CNTs and could provide useful theoretical guidance for design and fabrication of CNTs-based thermoelectric devices

Xiaoyan Sun,Yingnan Feng,Bin Zhang,Wuhao Huang,Xiaoliang Zhao,Hua Zhang,Dongsheng Yue,Changli Wang 대한암학회 2022 Cancer Research and Treatment Vol.54 No.4

Purpose The aim of our study was to investigate the value of baseline and preoperative neutrophil-to-lymphocyte ratio (NLR) in predicting the pathological response and disease-free survival (DFS) of neoadjuvant chemotherapy alone or combined with programmed cell death-1 (PD-1) checkpoint inhibitors in patients with resectable non–small cell lung cancer (NSCLC). Materials and Methods Resectable NSCLC patients who underwent neoadjuvant chemotherapy alone or combined with PD-1 checkpoint inhibitors between January 2018 and January 2020 were included. Peripheral venous blood samples of the patients were collected within 3 days prior to the first neoadjuvant treatment and within 3 days prior to surgery. Results A total of 79 patients in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group and 89 patients in neoadjuvant chemotherapy alone group were included. Thirty-five point four percent of the patients achieved pathological complete response (pCR) in neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group, whereas only 9.0% reached pCR in the group of neoadjuvant chemotherapy. High NLR level were correlated with poor pathological response and DFS in neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors group. Multivariate analysis revealed that baseline NLR could independently predict pathological response and DFS in the neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors group. Conclusion High NLR level were correlated with poor pathological response and shorter DFS in patients with NSCLC undergoing neoadjuvant chemotherapy or combined with PD-1 checkpoint inhibitors. Meanwhile, baseline NLR could independently predict response to pathological response and DFS, revealing its potential as a screening tool in NSCLC patients who received neoadjuvant chemotherapy combined with PD-1 checkpoint inhibitors.

Xiaoyan Hao,Jianping Li,Shengqi Gao,Zumuremu Tuerxun,Xiaochun Chang,Wenran Hu,Guo Chen,Quansheng Huang 한국유전학회 2020 Genes & Genomics Vol.42 No.12

Background: Abiotic stress effects agricultural production, so research on improving stress tolerance of crop is important. Suaeda salsa is a halophyte with high salt and drought tolerance and ability to desalinate saline soil and improve soil quality. Objective: To discover and utilize of salt and drought tolerance-related genes, we further investigated the mechanisms of salt and drought tolerance. Methods: Through screening a salt treated Suaeda salsa cDNA library and further cloning a H subunit of the photosystem I reaction center SsPsaH cDNA, and then the protein domain and phylogenetic analyses of PSI genes was conducted with the NCBI Blast, DNAMAN, and MotifScan programs. The S. salsa seedlings were subjected to various stress treatments and analyze expression of SsPsaH under these treatments by real-time RT-PCR. SsPsaH expression construct was introduced into S. pombe cells by electroporation and transformed into N. tabacum plants by the leaf disc transformation method. Results: A member of the H subunit of the Photosystem I reaction center (defined as SsPsaH) was obtained. The expression of SsPsaH was up-regulated by abscisic acid (ABA), salt, and drought stress treatments. Over-expressing SsPsaH in recombinant yeasts enhanced high salinity tolerance and increased tolerance to sorbitol during seed germination and seedling root development in tobacco, respectively. Some stress-related mark genes such as a LEA family gene of NtLEA, a binding protein of a drought response element of NtDREB, the ascorbate peroxidase gene (NtAPX) were also up-regulated in SsPsaH overexpressing transgenic tobacco lines. Conclusions: These results show that SsPsaH may contribute to the salt and osmotic stress response of plants.

The bubble problem of the plasma facing material: A finite element study

Xiaoyan Kang,Xiyue Cheng,Shuiquan Deng 한국원자력학회 2020 Nuclear Engineering and Technology Vol.52 No.10

The damage of first wall material in fusion reactor due to the bubbles caused by plasma has been studied by introducing a relation between the von Mises equivalent stress and the temperature field. The locations and shapes of the bubbles and the synergetic effect between the different bubbles under steady operational conditions have been studied using the finite elements method. Under transient heat loads, plastic deformations have been found to occur, and are significantly enhanced by the presence of the bubbles. The calculated concentration locations of von Mises equivalent stress are well consistent with the observed crack positions of the tungsten surface in many test experiments. Our simulations show that the damage of the bubbles is not severe enough to lead to catastrophic failure of the tungsten armor; however, it can cause local and gradual detachment of tungsten surface, which provides a reasonable explanation for the observed pits and rough or hairy surface morphology etc. Considering the transient heat loads, the lower bound of the security thickness of the tungsten tile is estimated to be greater than 2 mm.
