概要: パスワードは最も基本的な利用者認証方式である.印象に残りやすいパスワードを生成するには様々なノウハウがあり,機械的に生成する決定打はない.そこで,この研究では,日本語の文法違反を引き起こすと違和感を感じる事象に着目し,Google N-gramデータベースを単語出現頻度を考慮した生成方式を提案し,記憶力の差を定量的に評価する.

Guanine and xanthine nucleoside derivatives (3, 4 and 6) bearing nitrosourea functional groups were synthesized from guanine nucleoside ureas (2) obtained by the reaction of 2'-deoxy-2'-aminoguanosine (1) with isocyanates and their antitumor activity against sarcoma-180 solid tumor and leukemia L-1210 were determined. Among the compounds tested, 2'-deoxy-2'-[3-(2-chloroethyl)-3-nitrosoureido]-xanthosine (4b) found to have the most potent activity. Moreover, very slight decrease in white blood cells of mice bearing sarcoma-180 solid tumor was observed after administration of 4b.

Brevetoxins are powerful neurotoxins produced by dinoflagellate strain Gymnodinium berve Davis, isolated from the Florida “red tide” dinoflagellate. Their unique structure presents an opportunistic and formidable synthetic problem, particularly with regard to the construction of its medium-sized ring systems. This would almost certainly require new synthetic technology and a carefully designed strategy before yielding to total synthesis. This review deals with some new, practical and efficient synthetic technologies for the construction and chemical manipulation of medium-sized cyclic ether developed in K K.C. Nicolaou's laboratories.First total synthesis of hemibrevetoxin B (3) performed by these technologies is also delineated.

新潟特有の冬季低温寡照条件で、2004年秋から2005年春にイチゴ「越後姫」を温室ハウスで高設促成栽培し、灯油燃焼式の炭酸ガス発生機を用いて炭酸ガス施肥効果を検証した。炭酸ガスは日の出から5時間施用し、1月から3月の午前9時から12時までの平均炭酸ガス濃度は約1,500cm3 m-3であった。炭酸ガス施用でイチゴの硝酸吸収が促進されて葉色は濃く推移した。炭酸ガス施用区の累積収量は炭酸ガス無施用の対照区より17%増収した。規格別収量では炭酸ガス区で20g以上の大型果実が多くなった。また、炭酸ガス施用で果実糖度は有意に増加し、対照区より1.0~3.5度高くなった。以上、新潟の冬季気象条件で炭酸ガス施肥によるイチゴの増収および品質向上効果が認められた。The present study was made to investigate effect of CO2 application to strawberry cv. "Echigo-hime" for green house forcing culture in Niigata region, that the climate condition is low temperature and low amount of solar radiation in winter. Experiment was conducted from autumn 2004 till spring 2005 in Niigata University Shindoori Station. CO2 gas was applied from sunrise for 5 hours, and the average concentration was about 1,500 cm3 m-3, in the period in Jan. to Mar. in a.m. Leaf color CO2 treated plants was higher than the control, due to the active NO3-N absorption. And total yield increased about 17% compared with the control. CO2 treated plants had much harvest of big fruits of 20g or more. The sugar content (Brix) of fruits was higher about 1.0-3.5 degrees by CO2 treatment. Conclusion, CO2 application to strawberry was effective technique in that winter conditions as Niigata region.

イチゴ果実の着色は供試した白色蛍光ランプ,食肉展示用蛍光ランプのいずれを照射しでも着色し始めた果実の着色を促進した。その着色促進には,UVのみならず可視光線も関与していた。また,UVの作用は処理する果実熟度で大きく異なり,着色し始めた果実ではアントシアニン合成に促進的に作用し,着色が果実表面の1/2程度およびそれ以上に進むと抑制的に作用することが推察された。一方,イチゴ未熟果実の着色促進に有効なUV強度は供試した蛍光ランプのUV領域の総放射エネルギー量より,0.14W・m-2程度で十分と思われた。

This paper describes the investigations of the characteristic about the sound generation of a nose flute experimentally. The nose flute is attached to the upper part of a container. If air is passed to a nose flute, sound will occur. The volume of a container is changed and the generated sound is measured. The natural frequencies of an experimental device are calculated and we confirm that it is in agreement with frequency of sound generated in experiment. We show that nose flute is a unique musical instrument with the point that a nose flute has only an edge part and uses people's mouth for a resonance body part. The frequencies of resonance sound can be calculated from the capacity in a mouth, the thickness and the area of an opening of a nose flute. When people play a nose flute, it is thought that only the first mode of vibration is used.

In appealing to his lover or trying to "facilitate the study of the Japanese text, " Arthur Waley translated the 5-7-5-7-7-syllable tanka in five lines, often padding his translations in the manner of Robert Brower and Earl Miner. But in translating The Tale of Genji and Murasaki's Diary he incorporated most of the tanka into the prose, so that an inadvertant reader may never know that Genji contains nearly 800 tanka. Reading Waley's tanka translations incorporated into the prose text, one wonders if it may not be more natural to translate this verse form in one line. After all, unlike most English translators of tanka who believe with Waley that "the tanka is a poem of five lines, " most Japanese tanka writers, Tawara Machi of Sarada Kinenbi fame included, regard it as a "one-line poem." If one function of translation is to reproduce the original, shouldn't the attempt to do so include the line formation as well? Or if the breakup of the five syllabic units is to be stressed, why not go a step further and stress the syllabic count as well? What about the flow of the original? This paper looks at these questions by citing translations of Waley, Brower and Miner, Seidensticker, Bowring, Heinrich, Shinoda and Goldstein, Watson, LaFleur, Rodd and Hen-kenius, McCullough, and Carpenter against Sato's own monolinear translations.

This Paper discusses the possibilities and contributions of establishing 'design-oriented components', which provide flexible design for the A/E, and concludes follows. 1. The production system of component manufacturers has enough flexibility to accept special orders from the A/E since they have changed from production for stock to that for order. 2. There is no reason why the A/E selects ready-made components only for his design, nevertheless the idea of open system has been based on such components manufactured by the production system for stock. 3. It is essential to establish design-oriented components with which their information is represented by a means of operating their attribute easily. Such components are expected to gather A/E's needs for new developments by component manufactures.

沖縄県名護市の屋外生活主体の飼い猫に脱毛や掻痒の症状が認められ,セロファンテープを用いた皮膚検査により猫柔皮ダニ(Lynxcarus radovskyi)が確認された。フィプロニル・(S)-メトプレンのスポットオンとドラメクチン連日経口投与により症状は寛解し,その後の経過も良好であった。日本でも,沖縄のような亜熱帯地域では,臨床現場で本種ダニ寄生例に遭遇する可能性がある。
