Wei Shen,박혜숙 범태평양 응용언어학회 2020 범태평양응용언어학회지 Vol.24 No.1

This paper systematically reviews the studies of working memory in second language learning in China over the past 20 years. A total of 140 studies that were published in 13 major foreign language journals during the past 20 years (2000-2019) were categorized and analyzed according to research method, educational level, and research content. For research method, two phases could be identified: from 2000 to 2006, more attention focused on introducing theory and reviewing literature regarding the association between working memory and second language learning; and from 2007 to 2019, there is a growing body of quantitative and qualitative research. For educational level of the 75 empirical studies, the majority were targeted at adult learners, whose L2 proficiency was assumed to be at or beyond intermediate level. For the research content, they were classified into three dimensions: L2 understanding, L2 output, and the integration of L2 understanding and output. These three dimensions were sub-divided into a total of seven aspects: vocabulary, grammar, listening, reading, speaking, writing, and interpretation. Considerable advances have been made in the knowledge of working memory and second language learning. Nevertheless, more research is needed to develop a deeper understanding of the interrelationships between working memory and different domains of second language learning.

Adaptive Fuzzy Sliding Mode Control Based on Pi-sigma Fuzzy Neutral Network for Hydraulic Hybrid Control System Using New Hydraulic Transformer

Wei Shen,Jiehao Wang 제어·로봇·시스템학회 2019 International Journal of Control, Automation, and Vol.17 No.7

Control issue is the key for applying hydraulic hybrid system, especially for common pressure rail (CPR)system which has the huge potential to enhance efficiency. In the paper, the mathematical model of hydrauliccylinder speed control system using new hydraulic transformer is established. Then an adaptive fuzzy sliding modecontroller based on Pi-sigma fuzzy neutral network is designed to solve the problem of parameter uncertainty andnonlinearity without establishing the precise model. Furthermore, compared to PID and conventional adaptivefuzzy system, the controller proposed can achieve good control performance and strong robustness in the presenceof time-varying uncertainty.

The Effects of Meta-cognitive Strategies, Working Memory Capacity and Syntactic Awareness on L2 Reading Comprehension

Wei Shen,박혜숙 범태평양 응용언어학회 2018 범태평양응용언어학회지 Vol.22 No.2

The present study explores the effects of meta-cognitive strategies, working memory capacity (WMC), and syntactic awareness on Chinese EFL learners’ L2 reading comprehension. One hundred and sixty-seven Chinese college students who were enrolled in the required English class, aged from 19 to 21 years, participated in this study. A questionnaire related to meta-cognitive strategies, a reading span test, a syntactic knowledge test, and a reading comprehension test were administered to the participants to collect data. Descriptive statistics, one-way ANOVA, a correlation analysis, and a multiple regression were used to analyze the data. Results showed that there were significant differences in meta-cognitive strategy use, working memory capacity, and syntactic awareness among three groups of differing English reading abilities. Syntactic awareness was the most strongly correlated with reading comprehension. The result of a regression analysis indicated that meta-cogitation, WMC, and syntactic awareness all showed a statistically significant prediction for L2 reading comprehension. Accordingly, the results suggest that instruction for developing reading comprehension should prioritize syntactic awareness, and then focus on the activation of WMC together with the use of reading strategies for successful reading comprehension. From the results, some practical implications to effectively improve L2 reading comprehension are provided at the end.

Fatigue Life Evaluation of Welded Joints Considering the Local Multiaxial Stress/Strain States and Numerically Determined Residual Stresses/Strains

Wei Shen,Renjun Yan,Xiaoxing Wang,Enqian Liu,Lin Xu 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.1

This paper puts forward a kind of calculation method of estimating fatigue crack initiation life by considering welding residual stresses as initial stresses. The numerical method could be used to quantitatively analyze the influence of residual stresses on the cumulative fatigue damage. In order to gain the distribution of weld-induced residual stresses, the FE analyses as well as measurements were carried out. Based on critical plane approach, analysis of damage parameters was performed considering both welding residual stress and biaxial loads. Subsequently, validity of the proposed numerical method is verified by analyzing fatigue test results for several typical welded joints. It is concluded that the result of the present method is closer to the experimental value than that obtained with empirical formula method in the estimation of fatigue crack initiation life of welded structures.

Legitimacy Crisis and the ISDS Reform in a Political Economy Context

Wei Shen,Shuping Li (사) 이준국제법연구원 2022 Journal of East Asia and International Law Vol.15 No.1

The variation of countries’ industrial policies and political strategies in a multipolar world brings the investor-state dispute settlement (ISDS) regime to a crossroad. Backlash to the inconsistency, non-transparency, partiality and unfairness of the ISDS regime results from the states’ changing interests and policy priorities, including the rising awareness of democracy. In pursuing the benefits of multilateralism, a multilateral investment court can serve as an alternative to the current investment arbitration regime. States need to clarify the scope of consent based on their political economic considerations. Substantial investment protection standards can be different, whereas the principle of proportionality can serve as an approach to the balance between investment protection and states’ policy arrangements. Meanwhile, there should be efforts to align the interpretation and application of key provisions, possibly through interpretation notes and an appellate body that reviews arbitral decisions, to generalise implicit consensus and to broaden collective acceptance of the regime.

High-precision Position Tracking Control of Electro-hydraulic Servo Systems Based on an Improved Structure and Desired Compensation

Wei Shen,Xinyu Liu,Xiaoyu Su 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.11

How to improve the position tracking accuracy of electro-hydraulic servo system is a hot issue today. Full state feedback control has received widespread attention for its ability to significantly improve control performance,however, its practical application range is limited in view of the large influence of measurement noise. In terms of this issue, we propose an adaptive robust controller based on improved structure and desired compensation. Firstly,to reduce the impact of measurement noise, the actual state value is substituted by the corresponding desired value in the controller design based on model compensation and the adaptive model compensator. Then, we introducea new auxiliary variable into the controller to optimize its structure. In addition, nonlinear robust control laws are integrated in the controller to balance unstructured uncertainties. Simulation analysis shows that the proposedcontrol strategy not only achieves the asymptotic tracking when parameter perturbation exists, but also ensures a specified transient response and final tracing precision under the combined influence of structured and unstructureduncertainties. The results indicate that the control strategy has good control accuracy as well as strong robustness

???(Zhang Weishen) 한국고대사탐구학회 2016 한국고대사탐구 Vol.24 No.-

From the early Tang Dynasty to Emperor Gaozong and Emperor Wu zetian’s reign time, appreciation of calligraphy and painting was so popular among the upper class in power.During that time, the vertical shaft of calligraphy and painting was called “Zhang”(including paingting zhang, picture zhang, soft zhang etc.).When the upper class in power was appreciating the calligraphy and painting with vertical shaft, three display methods were used. First, Zhang (in the shape of Chinese character “丁”)and fork (in the shape of Chinese character “丫”)were used to hang the calligraphy and painting with vertical shaft. Second, in the Qujiang gala or banquet of aristocrats, calligraphy and painting with vertical shaft were hanged on a shelf by Zhang (in the shape of Chinese character “丁”)and fork (in the shape of Chinese character “丫”). Third, the maidservants used the Zhang (in the shape of Chinese character “丁”) and fork (in the shape of Chinese character “丫”) to hang the vertical shaft of calligraphy and painting to the crossbeam of the hip roof, which was reflected in the tomb of princess or high level.

당 나라 고분 벽화 속에 시녀가 든 ‘정(丁)’자형 막대의 용도에 대한 고찰

張維愼(Zhang Weishen),王天泉 한국고대사탐구학회 2016 한국고대사탐구 Vol.24 No.-

당 나라 초기부터 고종무후(高宗武後)시기까지 통치자 상층계급이 서화를 감상하는 것이 하나의 풍습이었다. 당시 서화 족자를 장(障, 畫障, 圖障, 軟障등이 포함된다.)이라고 불렀다. 통치자 상층계급이 서화 족자를 감상할 때 전시 방법은 최소 다음 3가지가 있었다. 1. 사람을 시켜서 정(丁)자형 장간(障竿, 대나무 막대기)이나 아차(丫叉, 두 가닥인 丫자형나무 막대기)로 서화 족자를 높게 내걸고 직접 전시하였다. 2. 곡강 성회 혹은 귀족의 연회에서 정(丁)자형 장간이나 아차로 서화 족자를 지지대에 걸어놓고 전시하였다. 3. 시녀를 시켜서 정(丁)자형 장간이나 아차로 서화 족자를 무전(廡殿)의 들보에 걸어놓고 전시하였다. 이 것은 공주 혹은 고위 계층들의 무덤 벽화에서 많이 나타나있었다.
