Jiying Han,Hongbiao Yin,Wenlan Wang 서울대학교 교육연구소 2015 Asia Pacific Education Review Vol.16 No.4
This study addresses a paucity of research into teacher motivation in higher education by exploring the relationship between tertiary teachers’ goal orientations for teaching and their approaches to teaching in China. A questionnaire gathered responses from 262 Chinese tertiary teachers, and the results showed these teachers reporting higher levels of relational and mastery goals for teaching and greater student-focused approach to teaching. Male teachers reported lower levels of ability-approach and mastery goals than female teachers, and teachers with no more than 5 years of teaching experience scored higher on both ability-approach and ability-avoidance goals than those with more than 15 years of teaching experience. The study also revealed that teachers’ ability goals significantly predicted a teacher-focused approach to teaching, and mastery goals predicted a student-focused approach to teaching.

Illumination Invariant Chinese Chessboard Reconstruction Based on Color Image
Jianjun Fang,N.Kondo,Jiying Yin,Xiuhong Liu,Kexian Xiao 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
This paper introduces a new approach based on binarized Gabor filters and Hough transform to reconstruct Chinese chessboard by computation. Firstly, Gabor transform is performed directly on an original color image of chessboard to obtain Gabor filters in which only interested lines are kept by selecting appropriate parameters. Secondly, Gabor filters image is binarized and thinned and then lines are detected by Hough transform. Thirdly, a binarized Gabor filters’image is affine rectified and three parameters which dominate reconstruction of chessboard are measured and coordinates of any crossing points in the chessboard can be calculated based on priori information and measured data. Finally, experiments have been conducted to verify illumination invariant feature of proposed approach. Results reveal that this new approach is more robust to illumination change. Comparing to conventional method, it is obviously superior and has been applied in a robust machine vision system for Chinese chess playing robot.

A feeding trial was conducted to investigate effects of Bacillus licheniformis on growth performance and meat quality of broilers. Nine hundred one-d-old broiler chicks were randomly assigned to 3 experimental groups with three replicate pens of 100 broiler chicks. Three treatments were i) control, ii) basal diets supplemented with 1 ml of B. licheniformis for each in feed water per day iii) basal diets supplemented with 2 ml of B. licheniformis per chick in feed water per day. The supplementation of B. licheniformis significantly increased body weight in grower chickens (p<0.05), and significantly improved the feed conversion in 3 to 6 and 0 to 6 wk feeding period compared with the control group (p<0.05). Additionally, the supplement also resulted in increased protein and free amino acid contents, and decreased fat content in chicken breast fillet (p<0.05). Furthermore, improvement in sensory attributes was observed in broilers fed with the probiotic. In conclusion, B. licheniformis treatments resulted in a significant increase (p<0.05) in broiler productivity based on an index taking into account daily weight gain and feed conversion rate. Meanwhile, the probiotic contributed towards an improvement of the chemical, nutritional and sensorial characteristics of breast fillet. Overall, the study indicates that B. licheniformis can be used as a growth promoter and meat quality enhancer in broiler poultry.
