Teachers’ emotional experience: insights from Hong Kong primary schools
Wu Zhenli,Chen Junjun 서울대학교 교육연구소 2018 Asia Pacific Education Review Vol.19 No.4
This study aims to understand teacher emotions through interviewing 28 primary teachers in Hong Kong. The study employed content analysis to analyze the data. The results were allocated to three dimensions of teacher emotions—student and learning, teacher and teaching, and the contextual factors. These teachers described 78 emotions of which approximately an equal number were positive and negative. Emotions relating to the student and learning dimension are the most intense, followed by those in the teacher and teaching and contextual factor dimensions. Data also indicated that teachers can hold positive and negative emotions simultaneously (e.g., happy yet pressurized by child’s unconditional trust) and can suffer from paradoxical emotions (e.g., regarding education reform). Teachers demonstrated different ways to manage emotions contingent on their demographic background. Given the powerful role that emotions play, recommendations for including teacher emotion education in both initial teacher education and professional development have been proposed accordingly.
Mechanical analysis for prestressed concrete containment vessels under loss of coolant accident
Zhen Zhou,Chang Wu,Shao-ping Meng,Jing Wu 사단법인 한국계산역학회 2014 Computers and Concrete, An International Journal Vol.14 No.2
LOCA (Loss Of Coolant Accident) is one of the most important utmost accidents for Prestressed Concrete Containment Vessel (PCCV) due to its coupled effect of high temperature and inner pressure. In this paper, heat conduction analysis is used to obtain the LOCA temperature distribution of PCCV. Then the elastic internal force of PCCV under LOCA temperature is analyzed by using both simplified theoretical method and FEM (finite element methods) method. Considering the coupled effect of LOCA temperature, a nonlinear elasto-plasitic analysis is conducted for PCCV under utmost internal pressure considering three failure criteria. Results show that the LOCA temperature distribution is strongly nonlinear along the shell thickness at the early time; the moment result of simplified analysis is well coincident with the one of numerical analysis at weak constraint area; while in the strong constrained area, the value of moments and membrane forces fluctuate dramatically; the simplified and numerical analysis both show that the maximum moment occurs at 6hrs after LOCA.; the strain of PCCV under LOCA temperature is larger than the one of no temperature under elasto-plastic analysis; the LOCA temperature of 6hrs has the greatest influence on the ultimate bearing capacity with 8.43% decrease for failure criteria 1 and 2.65% decrease for failure criteria 3.

This paper proposes a new 2R1T PRS-PRU-PUR overconstrained parallel mechanism (PM). Firstly, the kinematics and stiffness are studied based on screw theory and strain energy. Compared with a typical 3-PRS PM, the main advantage of the proposed PRSPRU-PUR PM is that the orientational range β is improved by 50 %. Secondly, the original PM’s kinematic and stiffness performance are evaluated by using the global transmission index and stiffness index, which are 0.675 and 594 respectively, which causes the decrease of the efficiency of some configurations. Finally, the design parameters are optimized to enhance the PM’s kinematic and stiffness performance. The corresponding optimized indices were increased to 0.915 and 2171, respectively, confirming the validity of the optimal design method.
Identification of Homer1 as a Potential Prognostic Marker for Intrahepatic Cholangiocarcinoma
Wu, San-Yun,Yu, Ming-Xia,Li, Xiao-Gai,Xu, Shu-Fang,Shen, Ji,Sun, Zhen,Zhou, Xin,Chen, Xing-Zhen,Tu, Jian-Cheng Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7
Background: The aim of the present study was to analyze whether Homer1 is a potential prognostic marker for intrahepatic cholangiocarcinoma (ICC). Materials and Methods: The expression of Homer1 in ICC tissue was detected with immunohistochemistry and levels of protein in ICC and paratumor tissues were evaluated by Western blotting. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. Results: Homer1 expression was high in 67.4% (58/86) of ICC samples, and there was significant difference between ICC and adjacent noncancerous tissues (p<0.001); high expression was associated with poor histologic differentiation (p=0.019), TNM stage (p=0.014), lymph node metastasis (p=0.040), and lymphatic invasion (p=0.025). On Kaplan-Meier analysis, a comparison of survival curves of low versus high expressors of Homer1 revealed a highly significant difference in OS (p=0.001) and DFS (p=0.006), indicating that high expression of Homer1 was linked with a worse prognosis. Multivariate analyses showed that Homer1 expression was an independent risk factor predicting overall survival[Hazard ratio(HR), 7.52; 95% confidence interval (CI), 2.63-21.47; p=0.002] and disease-free survival (HR, 11.56; 95%CI, 5.17-25.96; p<0.001) in ICC. Conclusions: Homer1 promotes lymphatic invasion and associates with lymph node metastasis and poor prognosis of ICC. The current study shows that Homer1 may be an independent prognostic factor for ICC patients after curative resection, and it provides an important basis for screening/treating high-risk patients.
On the Notion of “Unifying Ren 仁” in Wang Yangming`s Thoughts on Ren
( Wu Zhen ) 성균관대학교 유교문화연구소 2017 儒敎文化硏究(中文版) Vol.0 No.27
王陽明逝世前二三年開始竭力强調“萬物一體”論, 然而人們却往往忽略該命題的全稱“天地萬物一體之仁”的“仁”字。其實, “一體之仁”是陽明學重構萬物一體論的核心觀念、本體依據。以一體之仁爲根本旨趣的萬物一體論旣不同于先秦以來傳統的萬物一體論, 也有別于程顥的由“識仁”而進至“渾然與物同體”的仁者境界說, 而是新形態的以仁爲本的“仁學一體論”。陽明學萬物一體論旣是一項本體論論述, 也是工夫論命題, 更反映了“天下主義”的人文精神。陽明認爲由一體之仁的信念出發, 有望實現“天地萬物本吾一體者”的和諧共存的理想世界。 Two or three years before his death, Wang Yangming 王陽明(1472-1529) started to emphasize the “unity of all things” (wanwu yiti 萬物一體). In scholarly discussions of Wang’s notion of “ren which unifies all things in the universe” (tiandi wanwu yiti zhi ren 天地萬物一體之仁), the character ren 仁(benevolence/humaneness) is often overlooked. In fact, unifying ren (yiti zhi ren 一體之仁) is the central notion that Wang deploys to formulate his doctrine of the unity of all things. This notion is different from other traditional Chinese ideas about ren and unity, including Cheng Hao’s 程顥(1032-1085) teaching that emphasizes “knowing ren” (shiren 識仁) in the beginning and then progresses to “completely being as one with all things” (hunran yuwu tongti 渾然與物同體). In a word, Wang’s doctrine of the unity of all things is both ontological and practical and reveals the humanistic spirit of World-ism (tianxia zhuyi 天下主義). On the basis of a belief in unifying ren, a harmonious world where “all things in the universe are originally as one with me” (tiandi wanwu ben wu yiti zhe 天地萬物本吾一體者) can be created.
