Due to the paucity of systematic studies on Chinese friendship, this study compared 169 Japanese, 172 Taiwanese and 260 Chinese university students’ perceptions of friendship. A quantitative approach was chosen after examining the concept of “intersubjectivity” that indicates self as a creation of culture and as having shared dimensions with others in the culture. Specifically, a questionnaire including 30 questions about friendship (e.g., “I often visit my friend without telling s/he beforehand,” “When I worry about my parents’ quarrels, I talk about my worries with my friend,” “When I’m short of money and my friend has some, s/he will help me,” etc.) was constructed based on previous interviews and a preliminary descriptive study conducted in 2009.This study collected data in the three countries in 2009, and performed factor analysis to discover factors influencing participants’ friendship. The five factors that emerged included “closeness of social–distance,” “non–politeness,” “trustful relation,” “psychological burden” and “frankness with concerns of saving face,” respectively. Then, analysis of variance was utilized to compare the three groups in terms of the five factors. Results revealed the following two major findings:1. Chinese participants tended to show the closest and most trusting relationships paying least attention to manners, and to express their opinions most straight–forwardly to friends among the three groups.2. Japanese participants were inclined to indicate the farthest social–distance of the three groups, and to be concerned about manners most in order not to make friends feel uncomfortable.Theoretical discussion in the framework of Umesao’s “Ecological View of History” helped provide reasons for Chinese participants’ strongest personal bond with friends, followed by the Taiwanese, and the Japanese weakest relations among the three groups.

Cathinone-type designer drugs are a newly-encountered drug family that has a β-ketophenethylamine skeleton. Recently, the abuse of these drugs has been increasingly common among young adults, and this has caused a serious social problem in many countries. Many of those drugs have become regulated by the Pharmaceutical Affairs Act, and some of them were later banned by the Narcotics and Psychotropics Control Act in Japan, depending on their structures. In this paper, a total of 98 standards of cathinone-type designer drugs were synthesized, and their EI-mass spectra were acquired by GC/MS, with and without trifluoroacetylation. For their free bases, a major fragment ion formed from the α-cleavage of the amine nitrogen was commonly observed. Also, a small fragment ion generated by the α-cleavage of the carbonyl group, followed by the elimination of CO was detectable. For the analogs having an N-alkyl chain longer than methyl group and/or the alkyl side-chain longer than methyl group, a characteristic ion formed from the α-cleavage of the amine nitrogen, followed by the elimination of the olefin moiety was observed. For the trifluoroacetyl derivatives, the intensity of fragment ion formed from the α-cleavage of carbonyl group significantly increased, while that of the fragment ion generated from the α-cleavage of nitrogen decreased, when compared with those of free bases. Also, the ion at m/z 110 was specifically observed for the cathinone analogs having a methylamino group. Those typical fragmentation patterns revealed by analyzing a series of analogs provide useful information for the characterization of cathinone-type designer drugs.

平成16年度は、アジア太平洋諸国7ヶ国で留学生政策に関する調査を行い、75人にインタビューした。その記録は、中間報告書「アジア太平洋諸国の留学交流戦略の実態分析と中国の動向」として平成17年3月にまとめた。この成果については、独自に立ち上げたホームページにおいても全文を掲載している。アドレスは以下の通りである。http://www.george24.com/~yoko39/publications.htm研究成果の発表としては、平成17年5月の異文化間教育学会年次大会でポスターセッションを行ったほか、平成17年7月のJAFSA(国際教育交流協議会)サマーセミナー基調講演、平成17年12月の早稲田大学21世紀COEプログラム第4回国際公開シンポジウム、平成18年3月のCIES比較国際教育学会50周年記念大会(ホノルル)、平成18年6月の中央教育審議会での参考意見提供、平成18年8月JAFSAサマーセミナーの分科会等で発表した。平成17年から18年にかけて、全国四年制大学に対して国際化と留学生政策に関する質問紙調査を行なった。50.5%という高い回収率を得て、その結果を最終報告書「岐路に立つ日本の大学〜全国四年制大学の国際化と留学交流に関する調査報告〜」としてまとめた。データからは、国際化のビジョンやミッションを持っている大学が極めて少ないこと、国際部門の専門職育成に熱心ではないこと、国立大学が国際化に熱心であり公立大学はあまり関心をもっていないこと、オフショア・プログラムがアジア諸国に比べて全く低調であること、留学生を日本社会の高度人材として捉えていないこと、受入れと送出し国の関係が大きく変化していることなどが判明した。激動するアジアの留学交流の渦の中で、日本はどのような視座でこれを見極め、どのような政策をとっていくべきなのかに関して、何がしかの参考資料を提供できたと考える。
