TAT モノガタリ ニ ミラレル タイジン フアン ノ アラワレカタ ノ トクチョウ ニツイテ : ジコ コウテイ イシキ トノ カンレン カラ

The purpose of this study was to evaluate the effectiveness of psychological projective method TAT (Thematic apperception test) as an assessment tool detecting interpersonal anxiety and affirmative self-consciousness on undergraduate students. On the first study, subjects’ narratives to all of TAT cards were analyzed in criteria of evoking high anxiety response and self-affirmatives. Eleven of TAT cards were selected as stimulus cards projecting anxiety and self-affirmative. Subjects responded to an interpersonal-anxiety questionnaire and a self-affirmative questionnaire, and they were asked to make narratives of selected eleven of TAT cards. The result showed that subjects with high interpersonal-anxiety gave narratives of conflicting or keeping a positive interrelationship with others. On the other hand, subjects with high self-affirmative gave narratives of having a positive interrelationship or expressing a positive expectation to their future. For the next study, five of eleven cards were selected in criteria of projecting high self-anxiety and self-affirmative; cards 1, 2, 9GF, 13B and 14 were selected. On the second study, post-TAT questionnaire items were created for feedback to subject’s self-understanding of anxiety or affirmative. And the responses of post-TAT questionnaire items were examined. Result showed that subjects with high-anxiety were sensitive to expression of gazing. Through responding to post-TAT questionnaire items, subjects noticed new aspect of interpersonal relationship and their self-recognition as a result

The Shock State of Itokawa Sample

One of the fundamental aspects of any astromaterial is its shock history, since this factor elucidates critical historical events, and also because shock metamorphism can alter primary mineralogical and petrographic features, and reset chronologies [1]. Failure to take shock history into proper account during characterization can result in seriously incorrect conclusions being drawn. Thus the Hayabusa Preliminary Examination Team (HASPET) made shock stage determination of the Itokawa samples a primary goal [2]. However, we faced several difficulties in this particular research. The shock state of ordinary chondrite materials is generally determined by simple optical petrographic observation of standard thin sections. The Itokawa samples available to the analysis team were mounted into plastic blocks, were polished on only one side, and were of non-standard and greatly varying thickness, all of which significantly complicated petrographic analysis but did not prevent it. We made an additional estimation of the sample shock state by a new technique for this analysis - electron back-scattered diffraction (EBSD) in addition to standard petrographic techniques. We are also investigating the crystallinity of Itokawa olivine by Synchrotron X-ray diffraction (SXRD)
