The Nankai University participated in the drafting of this significant national document on human rights, with three teachers invited one after another to work at the panel of experts under the drafting committee. In cooperation with the Raoul Wallenberg Institute of Human Rights and Humanitarian Law （RWlHRHL） of Sweden, the Research Center for Human Rights under Law School of the university held an international seminar titled ＂Formulation and Implementation of NHRAP- Swedish Experience.＂展开更多

The aim is to determine the nature and dimensions which allow us to attain the simulations in free space. We compare the behavior of a dipole antenna modeled by MOM-GEC with those obtained in free space. A method of moment (MoM) approach combined to the generalized equivalent circuit (GEC) modeling is applied to compute the input impedance of a dipole antenna resonating at 1.8 GHz. A parametric study is conducted to investigate the wall effects on the antenna performances. Also we study the convergence of the input impedance as a function of test function number. The current values with integral method (MOM) are compared with the computed values obtained from numerical methods such as the combined MOM-GEC. The simulated values agree with values obtained from numerical methods.展开更多

These children usually live with either one of their parents, relatives or family friends. Research shows that there are over 58 million left-behind children in China; 57.2 percent of them have one parent working in another city, 42,8 percent of the children have both parents working in another city,展开更多

MethodsA total of 5 809 students (2 904 boys and 2 905 girls) from 41 schools (29 middle schools and 12 high schools) who were going to take National College Entrance Examination of China (NCEE) and High School Entrance Examination of Shanghai (HSEE) in 2012 in Minhang District were included in this investigation. The eyesight data of the students, including myopia rates, the disturbing of myopia degree, the differences of myopia rate between different schools, the relationship between the myopia rate and sex, and the relationship between myopia rate and right or left eye, were analyzed. ResultsMyopia was found in 80.3% of the total students. The rate of myopia in high school was 84.0% (90.2% in key high school and 85.1% in general high school with significant difference between them). The rate of myopia in middle school was 78.2% (78.5% in key middle school and 77.9% in general high school without significant difference between them). The myopia rate of high school was higher than that of middle school (P<0.001). In high school, the myopia rate of girls (86.8%) was higher than that of boys (80.8%) (P<0.001). Among all students, the right eyesight (4.361) was lower than the left (4.389) (P<0.001). ConclusionThere is a poor situation in the eyesight of middle school students. The government should take effective measures to publicize the importance of the eyesight health. The education departments and the hospitals must establish the termly examination to decrease the occurrence rate of myopia.展开更多
