基于模糊综合评判方法的仰光河航道安全评估

应用模糊综合评判方法,分析仰光河航道的航道安全.将仰光河航道分成4个航段进行研究,考虑缅甸航运业的发展以及航道进出船舶的安全,对全部航道和每一段航道进行安全分析,基于航道情况、环境因素等,提出航道的模糊综合评判方法.该综合评判方法可以定量表示全部航道和每一段航道的危险度.

Students’ perceptions of the learning environment in tertiary science classrooms in Myanmar

We investigated students’ perceptions of their science classroom environments with the use of the What Is Happening In this Class? (WIHIC) questionnaire at the university level in Myanmar. The translated questionnaire was administered to 251 students in first-year science classes at a university. Both exploratory factor analysis and confirmatory factor analysis supported the reliability and factorial validity of the Myanmar version of the WIHIC. The constructs of the WIHIC were significantly correlated, but gender differences were not detected in correlations between WIHIC scales. Future research is needed to see if our Myanmar version of the WIHIC fits other samples in schools and universities in this context. It is also suggested that future studies include measures of student attitudes and academic achievement to permit investigation of associations between the learning environment and student outcomes in this country.
