Since 1970s, linear models such as autoregressive (AR), moving average (MA), autoregressive integrated moving average (ARIMA), etc. have been popular for time series data analyze and prediction. Meanwhile, artificial neural networks (ANNs), inspired by connectionism bio-informatics, have been showing their powerful abilities of function approximation, pattern recognition, dimensionality reduction, and so on since 1980s. Recently, deep belief nets (DBNs) which use multiple restricted Boltzmann machines (RBMs) and multi-layered perceptron (MLP) are proposed as time series predictors. In this study, a hybrid prediction method using DBNs and ARIMA is proposed. The effectiveness of the proposed method was confirmed by the experiments using CATS benchmark data and chaotic time series data.

常同的発話を呈した,語新作ジャルゴン失語 (neologistic jargon : Kerteszら 1970) の症例を経験したので報告する。本症例の発話には,呈示刺激や場面が変わっても同一の無関連語 (irrelevant word) が出現し,その無関連語を中心として,音韻的および意味的に関連した「語」が変化しつつ繰り返されるという常同的な特徴がみられた。この音韻的・意味的に類似した「語」への変化・反復のパターンは,語新作ジャルゴン失語における,音韻論的・意味論的解体を示唆するものであり,特に,本症例の常同的発話においては,これらの解体が同時に現象として現れていた。われわれは,この音韻論的および意味論的解体を呈する常同的発話の出現機序について,Dell (1986) およびMartinら (1992) の「相互拡散活性化モデル」 (interactive spreading activation model) を用いて,認知神経言語学的考察を試みた。

Indicating forecast of Learning through Experiencing Nature (LEN) from environmental education has become an urgent task for education in Japan. In this article, discussion is reviewed reflectively to explore the direction for solving the task.   In the first chapter, we organized social needs for LEN identified in domestic and overseas measures. In the second chapter, taking LEN for nurturing youth, we categorized it with regards to (1) object and practicing subject, (2) learning aims of educational fields, and (3) LEN programs. In the third chapter, focusing on training leaders, we indicated that people in the local community can be leaders as well as school teachers, and leading actor in school education.   In conclusion, we stated three points; (1) the requirements for accumulation of empirical research in nurturing youth like clarification of the relationship between LEN and competence, (2) research and development with new viewpoints which are training leader as “interpreters” who can be communicators eliciting people's positive world view of nature, and (3) framing system which have a view to the relationship between LEN and local systems of environmental education for sustainable and symbiotic community development.

A hierarchical data analysis was conducted using data from couples to examine how self-reports of interactions between partners in romantic relationships predict the quality of the relationships. Whereas the social exchange theory has elucidated the quality of relationships from the individual level of subjectivity, this study focused on the structure of interactions between the partners (i. e., the frequency, strength, and diversity) through a process of inter-subjectivity at the couple level. A multilevel covariance structure analysis of 194 university students involved in romantic relationships revealed that the quality of relationships was mainly related to the strength and the diversity of interactions at the couple level, rather than the strength of interactions at the individual level. These results indicate that the inter-subjective process in romantic relationships may primarily explain the quality of relationships.

品質が向上し,いわゆる欠陥のある商品というのは少なくなった。そこで注目されているのは,人の感覚によって呼び起こされ,それによって支配される感情,欲望などといった感性の世界である,感性は,こころ(感情・記憶)でもあり,からだ(反射・運動)でもある。感性刺激に対し言葉によってかたられる官能評価はもちろん大切ではあるが,ヒトの脳や体の部位にどのような応答が現れるのか近年様々な研究が行われている。筆者は,ビールの「のど越し」という,それまで官能的に表現されていたものの混沌としていた感覚に果敢に取り組み,客観的にこれを計測する技術を開発された。ビールにとどまらずその研究の価値は広がっており,新たな分野を開拓している。

When an elevator rope for a high-rise building is forcibly excited by the displacements of the building induced by wind forces and/or by long-period ground motion, rope displacement becomes large even if the ground acceleration and the buildings acceleration are small. In previous paper, when elevator cage is stationary, a new practical method for reducing the rope vibration by using vibration suppressors is proposed for relaxing the restricted elevator operation. The advantage of using the vibration suppressors for reducing the rope lateral vibration is demonstrated through numerical calculation. Further, when arbitrary position of the rope is pulled, exact solution to the free vibration of the rope with vibration suppressor, which located at the center of the rope and the gap between rope and vibration suppressor is 0, has been presented. However, in the case where the position of vibration suppressor is center of the rope and the gap between rope and vibration suppressor is not 0, no exact solution to the free vibration has yet been obtained. In this paper, an exact solution to the free vibration of this case is presented. In the analysis, the rope is modeled with string. Finite difference analyses of the rope vibration with vibration suppressor are also performed to verify the validity of this exact solution. The calculated results of the finite difference analyses are in fairly good agreement with those of the exact solution.

This study aimed to evaluate the influence of radiographic abnormalities of 2-year-old Thoroughbred horses that were listed at in-training sales in Japan, on whether they started to race or not at 2–3 years of age. Radiographs of 850 2-year-old Thoroughbreds in the in-training sales repository from 2007 to 2010 were reviewed, and 26 categories of radiographic abnormalities were found. Forty-three horses (5.1%, 43/850) did not start a race at 2–3 years of age. In accordance with the racing results for this age category, as determined by Fisher’s exact test and multiple logistic regression analysis, none of the radiographic abnormalities were significantly related to failure to start a race. At 2 years of age, 198 horses (23.3%, 198/850) did not start a race. Horses with enlargement of the proximal sesamoid bones in the fore (9 of 19 horses) and hind limbs (5 of 9 horses) did not start a race at the age of 2 years, and fewer of these horses (fore, P=0.021; hind, P=0.030) started a race at the age of 2 years compared with the population of horses without these radiographic abnormalities. These results suggest that identification of radiographic enlargement of the proximal sesamoid bones during training sales could derail the racing debut of horses at the age of 2 years. However, this might not necessarily indicate a poor prognosis and resulting in retirement from racing at 2–3 years of age.

Fungal content of 24 samples of various types of spices of which a half was domestic and the others were collected from the markets in U.S.A., was surveyed from the hygienic point of view on foodstuffs. From 15 mold-positive samples, 12 were estimated under heavy contamination. Twenty eight fungi were isolated from these spices and were identified. Except a few Fungi Imperfecti and Mucorales, the majority of the species was found to be belonging to the genera Aspergillus and Penicillium. In the genus Aspergillus, the members of A. glaucus, A. flavus, A. niger, A. terreus and A. versicolor groups were the predominant species on the Japanese samples. In Penicillium, the series commonly found was P. chrysogenum only appearing in paprika of Japanese sample. The important contaminants in U.S.A. samples were identified as representatives of the A. glaucus group. No aflatoxins were detected in CHCl3 extracts of the rice culture of A. flavus which were found in Japanese sage and pepper. Since some spices such as garlic powder are known to have a bacteriostatic or bacteriocidal property, it may be suggested from the result obtained that some spices are not subject to spoilage.

The project which uses the wild boar meat by the measure against wildlife damage of Nakagawa town as a local specialty was investigated. The opportunity of the project originated in the dense relation between the local administration and a hunting group. In order to solve the subject of the area, administration was promoting the project by the implementation structure which connected each sector. The increase in a hunter's hunting volition and strengthening of a sense of solidarity with a local activity, and promotion of the eagerness to sell of the specialty by the wild boar meat of a retail store were accepted as a result of this project.

Both positivity and negativity are important components for the development of mother-offspring relationship. The "inter-body antagonism" is an important biological framework to promote offspring's independence from mothers. Weaning, an achievement of nutritional independence in offspring, is a typical situation in which mother-child negativity plays an important role. Human mother-child separation is also actualized by complex sociocultural allomothering systems consisting of objects, persons and institutes. Human triadic relationship in joint attention by mother and infant to object is a basic element of the systems. The relationship is preceded by "Proto-triadic relationship" in which particular body parts are used as targets in human inter-body interactions as in a case of tickling play.Not only object but also person could be a target of attention in triadic relation, and exchange of perspectives with the person is essential in the human infant's cultural learning and establishment of social network. A special allomothering by a girl called Moriane in an island of Okinawa is an example of such allomothering.
