This paper analyzes the suffix "mi" connected with nouns often used on Twitter, by comparing the difference between "kodomomi," "kodomopposa," and "kodomorashisa."Results reveal the unique function of "atarashii mikei" that is not observed in other formats. Moreover, it presents the following two points.First, using "atarashii mikei," a long noun phrase can be taken as its word base.Second, using "atarashii mikei," connections can be found and impressions described despite a weak relationship between the word base and object.

We improved the carrier mobility of the pentacene thin film transistors (TFT), which were fabricated with polysilsesquioxane (PSQ) gate dielectric layers, from 0.082 to 0.31 cm2V-1s-1 by treating the PSQ surface with ultra-violet irradiation (UV)/O3 and 1,1,1,3,3,3-hexamethyldisilazane (HMDS). It was found that the PSQ layers were flattened by the UV/O3 treatment, and the PSQ surface became hydrophilic at the same time because the organic functional groups on the PSQ surface were changed to hydroxyl groups. The grains of the pentacene films deposited on the UV/O3-treated PSQ surfaces were found to be as large as a few microns. However, the carrier mobility of the pentacene TFTs was not so much improved as expected from the largely grown pentacene grains probably because the hydroxyl groups scattered the charged carriers. In addition, the off-current of the pentacene TFTs increased by 4 orders of magnitude. It is thus considered that the hydroxyl groups also worked as hopping sites for the increased off-current which flew without the gate voltage. On the other hand, the carrier mobility of the pentacene TFTs fabricated with the PSQ dielectric layers of which surfaces were treated with UV/O3 and HMDS became ~4 times larger than that without any surface treatment of the PSQ layers, and also the off-current decreased by 3 orders of magnitude because the hydroxyl groups were changed with silyl groups by the HMDS treatment.

室町後期から江戸期にかけて作られた謡伝書にはしばしば五十音図が掲載されており,行段それぞれに謡曲独自の発音注記が付されている。本稿ではそれらの発音注記を精査し,おおよそ二系統に大別できることを明らかにした。一つは悉曇学の影響が強い系統で,行を「口喉舌唇」,段を「上音/中音/下音」の対立で捉えるものである。もう一つは,室町後期以降に権威のあった『塵芥抄』系伝書の系統であり,行を「喉舌歯腮鼻唇」,段を「ひらく/ほそむ/すぼむ」の対立で捉えるものである。『塵芥抄』系伝書の五十音図とその発音注記は,近世の謡伝書や学問書には直接引用されていないものの,処々にその影響を窺わせる記述が見られる。タ行の調音に「腮」を用いて説明している点等は『蜆縮涼鼓集』の記述とも共通しており,近世期における日本語音の把握には,『塵芥抄』系伝書の影響が少なからずあったと考えられる。
