The gap between the accerelated physical growth and the stayed or relatively delayed mental development has become common in many countries. In this sense, the study on sexual maturation has to cover not only the physical but also the mental aspects. Age at menarche, the knowledge of sexual phenomena, and the behavioural pattern at counselling of sexual problems were the content of questionnaire. The subjects were girl students at Eiwa Junior and Senior High School in Yamanashi Prefecture. The results are summarized as follows: (1) Age at menarche has become younger annually. (2) Psychological reaction toward menarche differed dependent upon the age at it. (3) After menarche, students became more conscious to sexual phenomena, and tended to select persons other than parent as the counseller. (4) The amount of knowledge on sexual phenomena increased with the chronological age, but the understanding of underlying mechanism did not show a simply increasing pattern. (5) The age at menarche and the feeling invited by the menarche seemed to influence the increase of knowledge and the deepening of understanding. (6) By the content analysis of the answer to questionnaire, the development in intelligence was supposed to relate closely to the advancement of knowledge on sexual matters.

結実期の環境条件は,種子活力に影響を与える要因の一つである.ニュージーランドでは,エンドウマメ(Pisum sativum L.)種子の出芽率は,発芽率に加えて2つの種子活力判定試験の結果(電気伝導法(EC)およびhollow heart (HH)発生率)を組み合わせて算出する.本研究では,まず,同国の5つの主要採種地域(Masterton, Blenheim, Christchurch, AshburtonおよびTimaru)において,過去4シーズン(2001-2, 2002-3, 2003-4および2004-5)に生産されたエンドウマメの中生品種の種子を収集し,その種子活力に地域間差やシーズン間差はあるか,気象条件は種子活力の高低に影響しているか検討した.採種した種子のECおよびHH発生率には,地域間およびシーズン間で変動した.そして,エンドウマメの種子活力は,2月の気温と有意な相関関係があり,同月の気温が高くなるほど活力が低下することが明らかとなった.次に,有意な相関関係から得られた単回帰直線を用い,過去12シーズンの気象データから,各採種地域で生産される種子活力を予測した.予測されたECとHH発生率は,5つの地域間で有意に異なった.これらのことから,ニュージーランドでは,採種地域を選ぶことで,活力の低いエンドウマメ種子を生産するリスクを下げることが可能であると考察された.

The government, companies and universities in Japan have been emphasizing the importance to educate young people to be competent in globalized business world. Assuming gap year as one of tactics to train the young Japanese, increasing attention has been paid to gap year in Japan, and as a result, the factual knowledge about gap year has been gradually accumulated. Now we know that gap year is a traditional custom in the UK, the number of British participants of gap year, who are involved in it, and the varieties how it is conducted. However, the stakeholders' recognition on gap year in the UK has not been investigated in detail. It would be important for Japanese stakeholders to know how stakeholders in the UK think on gap year in order to attract and encourage the young Japanese to participate such a mental energy consuming activity. A piece of qualitative research is conducted on and it is found that the gap on assumptions on purpose of gap year between those who believe that gap year is an effective way to enrich individual's CV and those who assume that it is one of opportunities to develop the world citizenship. These assumptions are not clearly recognized by the participants. It is important to clarify the purpose of the gap year when universities conduct gap year as part of their programs.

清酒中での脂肪酸の閾値を, エタノール濃度15%(v/v) のホワイトリカーをべースにして測定した結果, 酢酸39.3ppm, 酪酸2.7ppm, カプロン酸2.3ppm, カプリル酸2.4ppm, カプリン酸3.1ppmとなった。また, 酢酸, 酪酸は酸臭, カプロン酸, カプリル酸, カプリン酸は油臭と感じる傾向にあることが分かった。清酒に脂肪酸を添加したときの官能評価を4種類の清酒をべ一スにして行った結果, 酢酸, カプリル酸, 酪酸, カプロン酸, カプリン酸の順に評価が悪くなることが分かった。酢酸を60ppm添加しても無添加のものと有意な差はなく, 官能評価には影響しないことが分かった。逆に酢酸以外は4ppm又は8ppm添加すると無添加のものと有為な差が生じ, 官能評価にマイナスの影響を与えることが分かった。酢酸, 酪酸は酸臭, カプロン酸, カプリル酸, カプリン酸では油臭, ほこり臭, ろ過臭, 袋香という指摘が多かった。最後になりましたが, 官能評価にご協力いただきました各審査員に深謝します。

血中のグルコースは, 膵β細胞内で代謝を受け細胞内ATP濃度の上昇となって表れる. 細胞内ATP濃度の上昇をATP感受性カリウムチャネルが感知しチャネルを閉鎖することにより, 膜電位が上昇し電位依存性カルシウムチャネルが開口し, 細胞内カルシウム濃度が上昇し, インスリン分泌が惹起される. したがって, ATP感受性カリウムチャネルは糖代謝の変化をカルシウムイオン濃度の違いに変換する上で鍵となる蛋白と考えられる.

Human nature is a product of human brain activity, and human brain is an organ which functions to assess environmental information and to make decision about what to do next. Many aspects of human nature must be the results of evolution through natural selection in which favorable genes were selected under the environmental stress. Now, we live in civilized societies based on highly developed technology, using computers, contemplating about the relativity theory, mastering the calculus etc. However, this was not an environment where our basic human nature evolved. That environment was the one which surrounded our ancestors. Humans lived as hunter-gatherers in most of the time during evolution, and the human brain evolved to solve those problems confronted at those times. The resulting decision-making algorithms were so flexible that we can now deal with novel problems of our time using the same old decision-making algorithm. The evolution of behavior is a very complex process and no one gene is controlling any particular behavior. Genes are indeed involved in producing adaptive behavior but a behavior is produced through many other pathways as well, such as learning. We have evolved a huge brain which is capable of producing culture. Culture is a human creation but at the same time, culture has become our environment to which we have to adapt. Thus gene-culture coevolution has been a very important process in human evolution. After we have acquired language, perhaps we have acquired an almost unlimited cognitive power. Many of our cultural invention is the results of our cognitive activity and these things have become parts of our environment. However, cognition is only a small part of the workings of our brain. Human nature is also under control of emotion. Emotional processes are mostly subconscious and have changed little through evolutionary time. In the future, misfits between our cognitive products and emotional process may create many difficult problems which we have never experiences so far.
