Herein, we report signifcantly enhanced mechanical properties and thermal conductivity of polyimide (PI) by incorporating a small amount (0.01 wt %) of individualized boron-doped high-quality graphene as a fller. The boron-doped expandable graphite (B-EG) was synthesized by mixing boric acid (H3BO4) with expandable graphite (EG) and thermally treating the mixture at 2450 °C for 30 min using a graphite furnace in an argon atmosphere. The boron-doped graphene (B-g) was pre�pared by the solution-phase exfoliation of B-EG with an ultrasonication process, which is a method to obtain individualized graphene as well as few-layer graphene. The PI nanocomposites were prepared using the obtained graphene. The PI nanocom�posites synthesized with high-quality B-graphene (B-g) showed enhanced mechanical properties and thermal conductivity compared to those of pure PI due to the doping efects and strong interfacial interactions between graphene and the PI matrix.

本稿は、谷崎潤一郞の作品の中でも芸術か、ワイセツかの論難の的となっていた『鍵』について考察しようとした。一生かかって性に対する自分の思想を作品の中に描いた谷崎が、『鍵』ではその性をまたどのように描いたのか、その性を通してどのような新しい物語を創造したのかを探ってみた。『鍵』は、前面に‘性’が描き出されているが、その裏側には登場人物の間、騙したり騙されたりする闘争が熾烈に描写されている作品である。性はこの作品の中でお互いに相手を動かす道具として働き、登場人物は性を利用して相手を自分の意図したとおりに動かそうとする。この熾烈な闘争には、主人公夫婦と敏子、木村が参加しているが、本稿では特に、敏子の役割に注目して新しい視線で考察しようとした。表面に現れていない彼女の隠れている心理を把握することによって、この小説に隠れているもう一つの権力構造を探してみようとした。敏子は自分の欲望の為に、木村と郁子をそそのかしたもう一人の隠れた主人公の役割をしているのである。このような敏子の存在意味を理解してからこそ、ようやく『鍵』を十分に理解することができるのであろう。

This study was carried out to compare physiological characteristics of winter green cultivar (Buxus microphylla van. koreana 'Hanlim') with those of native cultuvar and clucidate the effect of environmental factors such as light intensity, time of shading, and nutrients etc. on leaf color in Korean boxwood(Buxus microphylla var. koreana Nakai). The results are summarized as followed; The 'Hanlim' cultivar had higher contents of chlorophyll as compared with native cultivar from September, 1989 to March, 1990. However, at April, 1990, native cultivar had higher chlorophyll contents. In the rate of photosynthesis, 'Hanlim' cultivar was higher than native cultivar from September to December, 1989, but showed the opposite trend from March to April, 1990. As to the period of browning, 'Hanlim'cultivar had stayed green even after November 22, 1989, while the foliage of native cultivar turned yellowish brown color through the winter. The contents of nitrogen and potassium of 'Hanlim' cultivar werehigher than those of the native cultivar. However native cultivar had higher rate of phosphorus, magnessium, and calcium. In the effect of environmental factors such as light intensity, time of shading, and nutrients etc. on leaf color in Korean boxwood(Buxus microphylla var. koreana Nakai), chlorophyll contents were increased with shading and leaves grown 70% shading had twice as much as those of full sunlight, fertilized plot. Nutrient fertilization increased chlorophyll contents and values of color in boxwood too. In the shading times, early shading time maintained effectively green color of boxwood in winter. Therefore, in case of native cultivars, it has planted at full sunlight area until now and color of leaves turned yellowish brown color through the witner. However, it will maintain green color of leaves by planting at shade area. In addition to, as 'Hanlim' cultivar had benefits of maintain green color of leaves during winter, it will be planted at full sunlight area to landscape plants.
