The aims of this study are to develop and apply a Nature Game program for the ecological experience learning in Jeju Gotjawal forest and analyze the environmental sensitivity change of the students. The results obtained in 4th graders of A elementary school of Seogwipo-city are as follows: It was found that attention, susceptibility and practice will of environment protection for forest environment of the experimental class were significantly higher than those of the comparison class. And it was found that interest and curiosity into forest environment were also elevated in the results of the qualitative evaluation, suggesting that we could get the effect of developed Nature Game program on ecological experience learning. If various ecological experience learning programs considering the regional-specific characteristics are developed to cause students' interest and curiosity, students would come to participate in the protection activity of environment aggressively a little more.

This study developed a ‘structure and function of our body’ program using visual thinking and applied it to analyze the effect on elementary school students’ selfdirected learning skills, creative problem solving ability and scientific attitude. The results of the program using visual thinking to sixth-grade students are as follows. First, the ‘structure and function of our body’ program using visual thinking is effective in improving the sixth graders’ selfdirected learning skills. In the sub-elements, the experimental group was significantly improved in intrinsic motivation, openness, and autonomy. We inferred that the intrinsic motivation has increased because they worked on learning in an acceptable atmosphere by organizing the contents the topic through drawing activities. In the process of sharing each other's drawing outcomes, they acknowledged each other's opinions and openly accepted others' opinions. And autonomy was improved in the process of learners planning and organizing their own learning. Second, there was no significant difference in understanding, diffusion, criticism, and motivation in the sub-elements, although it had a significant impact on improving the total score of their creative problem solving ability. Third, the program had a significant impact on improving scientific attitude. Cooperation increased in the process of communicating and discussing what they organized on their own. Therefore, the program using visual thinking learning strategies demonstrates that the approach might be effective in improving elementary school students' self-directed learning skills, creative problem solving ability, and scientific attitude.

Aircraft pylon connects the engine or external stores to the main wing, and transfers the load acting on the pylon to the main structure of the aircraft. In particular, it should perform the function of separating the external store mounted on the pylon in case of emergency or mission performance. At this time, if the separation of the external store is not performed properly due to peripheral air flow or functional problems during the separation process of the external store, it may seriously impact the survivability of the aircraft. For this reason, to apply an external attachment to an aircraft, it is necessary to prove the stability of the external attachment in the separation situation in advance. In this paper, we present the result of the ground separation test performed to confirm that the external fuel tank, which is an external attachment, can be safely separated from the pylon. As a result of the test, the separation movement of the external fuel tank was measured with a high-speed camera, and the stability of the separation of the external fuel tank from the pylon were confirmed through the ground separation test. Additionally, the test result provides basic data for the stability evaluation of the separation of external attachments in actual aircraft.
