Background: In Japan, introduction of severe drunk-driving penalties and a lower blood alcohol concentration (BAC) limit in June 2002 was followed by a substantial reduction in fatal alcohol-related crashes. However, previous research suggests that this reduction started before the legal amendments. The causes of the decrease have not been studied in detail.Methods: Monthly police data on fatal road traffic crashes from January 1995 to August 2006 were analyzed using a joinpoint regression model to identify change-points in the trends of the proportion of drunk-driving among drivers primarily responsible for fatal crashes. We analyzed the data by BAC level (≥0.5 or <0.5 mg/ml), then conducted analyses stratified by vehicle type (car or motorcycle) and age group (<45 or ≥45 years) only for the proportion of those with a BAC of 0.5 mg/ml or higher.Results: Among all drivers, the proportion of those with a BAC of 0.5 mg/ml or higher and those with a BAC greater than 0 but less than 0.5 mg/ml showed a change-point from increase to decrease in February 2000 and in May 2002, respectively. The proportion of those with a BAC of 0.5 mg/ml or higher showed a change-point from increase to decrease in October 1999 among car drivers and in April 2000 among drivers younger than 45 years. There was no change-point among motorcyclists. A change-point from no trend to a decrease in January 2002 was observed among those 45 years or older.Conclusions: The change-point identified around the end of 1999 to the start of 2000 suggests that a high-profile fatal crash in November 1999, which drew media attention and provoked public debate, triggered subsequent changes in drunk-driving behavior.

This paper introduces a framework that can extract an alpha matte from a single image with Fresnel reflection, and that can composite other objects with the image such that plausible reflections are included. Our method handles reflections in a plane with small undulations, for example, a water surface with waves or a glossy tabletop. During the matting stage, our method first estimates the transmission color, which is assumed to be uniform, and then calculates a reflection image and alpha matte based on user markups. However, accurate extraction of the matte becomes challenging when a plane has small undulations because these create perturbations in the matte. We therefore propose a filter that can refine the matte effectively. In the compositing stage, the reflection of a composited object is synthesized by ray tracing in real time. We demonstrate the effectiveness of our method through comparisons with ground-truth data and results using natural images as inputs.

Theme setting is important for science communications. But in many cases, it is not interactively. That is one reason to think people science communications are forced to accept scientific conclusions. Interactivity is an important key word on science communications. So I organized The Round Table Discussion in Okkope , a new type of science communication. In this Round Table Discussion, the participants can choose theme. The theme chose by the participants was “we want to eat products from our town”. It is not scientific theme but social issue. But scientific issues are necessary to discuss about this theme. We discussed about social issues from scientific theme. But this new type science communication is discussing scientific issues from social theme. This type of science communications is based on people’s own life. It is important to add this type of science communication.

In this paper, we consider the XPath satisfiability problem under restricted DTDs called “duplicate free”. For an XPath expression q and a DTD D, q is satisfiable under D if there exists an XML document t such that t is valid against D and that the answer of q on t is nonempty. Evaluating an unsatisfiable XPath expression is meaningless, since such an expression can always be replaced by an empty set without evaluating it. However, it is shown that the XPath satisfiability problem is intractable for a large number of XPath fragments. In this paper, we consider simple XPath fragments under two restrictions: (i) only a label can be specified as a node test and (ii) operators such as qualifier ([ ]) and path union (∪) are not allowed. We first show that, for some small XPath fragments under the above restrictions, the satisfiability problem is NP-complete under DTDs without any restriction. Then we show that there exist XPath fragments, containing the above small fragments, for which the satisfiability problem is in PTIME under duplicate-free DTDs.

The purpose of this treatise is to investigate intensively the history, principle and issuse of "Sotaiho" for the first time. The main results are as follows. 1) Comparing "Sotaiho" with "Seitaijutsu", the author proved the former to be obviously influenced by the latter, early in the Showa era. Moreover, Keizo Hashimoto, originator of "Sotaiho" puts more emphasis on natural and systematic movements of bodies, with a flavour of Oriental medicine and thoughts. 2) "Sotaiho" mainly consists of a variety of slow and "rebalancing" movements of bodies for comfortable feelings. 3) "Sotaiho" will be useful in medical treatment and school or community health education, etc. 4) The effectiveness and limitations of "Sotaiho" must be scientifically studied in actual cases hereafter.
