An adult male captured at Nakatsu village, Wakayama Prefecture, was identified as an interspecific hybrid between the Japanese and Taiwan macaques. Electrophoretic analysis of diagnostic blood proteins (adenosine deaminase, ADA; NADH-dependent diaphorase, DIA; transferrin TF) strongly supported the occurrence of hybridization between native Japanese macaques and artificially introduced Taiwan macaques in the prefecture. The male had a Taiwanese-like mitochondrial DNA. This suggested that the hybrid resulted from a mating between an immigrant male of Japanese macaque and a group-member, female Taiwanese macaque in the northern area of the Arida River.

During reading spaced text such as English, each word is not refixated very often when eyes initially land on slightly right side of the middle part of the word. However, in identifying an isolated word, the word will be identified more quickly when eyes initially land on slightly left side of the middle part of it. These two initial eye landing positions are called optimal viewing position or OVP, and these two phenomena are called optimal viewing position effect or OVP effect. This paper aims to simulate eye movements using a computer to realize these two OVP effects. Previous studies indicated that the reason for OVP in identifying an isolated word was that letters could be identified more correctly in the right visual field than the left. In our study, in order to get the higher probability of letter identification in the right visual field than the left one, we considered the asymmetry of the number of pixels sampled in the left and right visual field. And we used the gap between subjective and objective viewpoints to quantify the asymmetry. Here, a subjective viewpoint is defined as the point that people look at on an object. Meanwhile an objective viewpoint is defined as the point of the object, on which the straight line passing through the center of pupil and fovea falls. In our experiments, eye movements in identifying an isolated English word and reading English text were simulated using a computer while shifting the objective viewpoint around the subjective viewpoint. As a result, OVP appeared on the left half of a word and on the right half when identifying an isolated English word and reading English text, respectively. These happened only when the objective viewpoint was shifted to the right from the subjective viewpoint by the width of 1 letter.

This study aimed at evaluating the effect of habitual exercise and the level of daily physical activity on executive function (i.e. inhibitory control) and mental health status in youth adults. Twenty-four undergraduate- and graduateuniversity students participated in this study. All of the subjects underwent evaluations of their mental health (The General Health Questionnaire 28; GHQ28), inhibitory control (Stroop Color and Word Test), past- and current- exercise habits, and daily physical activity levels (International Physical Activity Questionnaire Short Version). Current habitual exercise and the level of low intensity physical activity were inversely correlated with score for GHQ28. Past habitual exercise was inversely correlated with reaction time for incongruent trial of the Stroop Color and Word Test. The level of vigorous physical activity was inversely correlated to the accuracy for incongruent trial. This study demonstrates that the level of low intensity daily physical activity may improve inhibitory control and maintain the optimal status of mental health, while the level of vigorous intensity physical activity might lead to an impairment of inhibitory control in youth adults.

微生物からのスクリーニングは,時として予想外の大きな発見をもたらす.真菌の形態異常を惹起する抗真菌抗生物質として東京大学の醗酵学研究室で発見されたレプトマイシンは,生命の根幹にかかわるタンパク質核外輸送因子の発見と画期的抗がん剤開発研究を可能にしたユニークな天然物である.レプトマイシンの標的として同定された機能不明のCRM1は,真核生物共通のタンパク質核外輸送因子であることが明らかになった.その後,CRM1は骨髄腫をはじめ多くのがんで重要な役割を果たすことが明らかになり,現在,最も大きな注目を集めるがんの分子標的の一つとなっている.本稿では,微生物スクリーニングから始まって,生物学上の重要な制御因子の発見と新たな創薬標的の発見をもたらしたレプトマイシンの物語を振り返ってみたい.

This paper deals with the discrete least square approximation of multivariable functions whose values are given only at the lattice points.First, the solution is obtained as a linear combination of the values of the function at the lattice points, and it is shown that the deterministic method requires evaluation of the sum of an extremely large number of terms.Next, to overcome this difficulty, the problem is converted into that of evaluating the expected values of two probabilistic models. An algorithm based on simulating these models by means of choosing the lattice points at random is proposed for the evaluation of these expected values. The method of sampling the lattice points is also discussed.Moreover, the following points are shown.(i) The values of the parameters which are necessary to execute the algorithm can be obtained easily regardless of the number of independent variables.(ii) In two typical cases the proposed algorithm requires less computational labour than the deterministic method.(iii) The algorithm is effective in the following situations:(a) The situation when the values (data) of the function to be approximated can be measured only at the lattice points(b) The situation when the function is a composite functionA numerical example is also presented.

High quality but low price is a fundamental factor for commodities, however, tangible and intangible added value is the most important factor for luxury products. To pursue added value of luxury fashion brands and products, this paper shed light online platform service dealing with a large amount of products, and aims to reveal the actual situation of the luxury fashion market. The importance of online platform service as a data source is discussed in terms of network externality required for modern services. This paper proposes sales amount analysis and analyzed 308,154 luxury fashion items. The results show availability of category extension in luxury brands to raise the sales. Integrity of high sales amount products is also discussed on brand equity fascinating consumers.
