Tongji University has recently carried out a test on the full-scale three-ring lining structure of Changjiang Tunnel. This paper introduces the testing processes, including loading apparatuses, test contents, test cases, etc., and makes comparison with other shield lining structure tests conducted before, and finally gives some evaluations on the design of the tunnel.展开更多

There are many similarities and differences between Chinese and British elderly university. This paper makes a comparative study on the educational goals, curriculum, content and activities of elderly university in China and Britain, which is beneficial to the elderly university of our country for reference to the development experience of the elderly university in Britain. The elderly university in our country should also adhere to the value orientation of social adaptation and self-realization theory, further update the curriculum content, carry out diversified teaching activities, meet the diversified needs of the elderly for entertainment, learning and development, and ultimately improve the quality of life of the elderly.展开更多

This is due to the advancement of technologies equipped in majority of the mobile phones which makes the devices become more capable of supporting the learning and teaching activities. Mobile learning （m-learning） is a learning tool which can be run on mobile devices. It can be considered as an enhancement to the electronic learning （e-learning）. M-learning overcomes several limitations of e-learning especially in term of mobility. It provides more independent way of learning whereby learners can use the application to do the learning activities at anytime and any place. However, as with other learning and teaching applications, applications to be developed for mobile learning must also be developed based on certain learning theories and guidelines in order for them to be effective as well as usable. Therefore, in this paper, the development process of a mobile learning course content application called Mobile System Analysis and Design （MOSAD） as a revision tool will be shared and its testing＇s conduct and results will also be presented and discussed. MOSAD was developed with the content of a topic from the System Analysis and Design （SAD） course conducted at Universiti Teknologi PETRONAS （UTP）. A heuristic test involving 5 experts in the area of Human Computer Interaction （HCI） were conducted after the first version of MOSAD was completed to strengthen its functionality and usability, followed by a Post Test Quasi Experimental Design which was conducted to 116 UTP second year students who took the SAD course to test the effectiveness and usability of MOSAD after it was revised. As a result from the post test, the students who had used MOSAD （66 out of the 116 students） as their revision tool for answering ten quiz questions obtained a mean score of 7.7576 as compared to 5.160 obtained by the other group of students （50 out of the 116 students） who used traditional methods of revision. Besides, usability test which tested on consistency, leamability, flexibility, minimal action and minimal memory load of MOSAD gave results above 3.5 for each metric based on the rating of 1 to 5. Thus, both results indicate that MOSAD is effective and usable as a revision tool for the higher education students.展开更多
