This study aimed to evaluate the perceived exertion and satisfaction in opening and closing SUV tailgates and explain them with the mechanical force. The study measured the mechanical open and close force for 42 SUV tailgates and evaluated perceived exertion and satisfaction of opening and closing with 100 male participants from 20’s to 50’s. The regression models of perceived exertion and satisfaction showed that small initial closing and opening force, difference between initial and maximum closing force and difference between initial and auto-fall angle have positive effect. The results of the study will be helpful to design and test mechanical open and close structure of SUV tailgates.

This study explored the effects of creativity-based L2 poem writing (CBLPW) for EFL college students. A total of 40 college students participated, who were assigned to two conditions-non-creativity and creativity groups. The present study employed pre-, post-, and delayed-tests for creativity using the Torrance Test of Creativity, pre-, post-, and delayed-evaluations of L2 poem writing quality, and pre- and post-questionnaires for participants' affective domain. The results showed immediate and sustained effects of CBLPW on creativity, and writing quality. In addition, an overall positive effect of CBLPW was observed in the affective domain such as interests, confidence, and motivation for the two groups. These findings suggest that teachers could offer students a wide range of creativity techniques in order to enhance their levels of creativity, L2 poem writing quality, and the affective domain of learners.
