This proposal aims to close gaps that have been identified in nuclear and radiological preparedness following the first evaluation of the Fukushima disaster. It addresses the call Fission-2010-3.3.1: Update of emergency management and rehabilitation strategies and expertise in Europe. The consortium intends to review existing operational procedures in dealing with long lasting releases, address the cross border problematic in monitoring and safety of goods and will further develop still missing functionalities in decision support system ranging from improved source term estimation and dispersion modelling to the inclusion of hydrological pathways for European water bodies. As the management of the Fukushima event in Europe was far from being optimal, we propose to develop means on a scientific and operational basis to improve information collection, information exchange and the evaluation for such types of accidents. This will be achieved through a collaboration of industry, research and governmental organisations in Europe taking into account the networking activities carried out under the NERIS-TP project. Furthermore, the NERIS Platform member organisations (so far 43 partners) will be actively involved in the development.

COMET will strengthen the pan-European research initiative on the impact of radiation on man and the environment by facilitating the integration of radioecological research. COMET will build upon the foundations laid by the European Radioecology Alliance (ALLIANCE) and the on-going FP7 STAR Network of Excellence in radioecology. By collaborating with the European platforms on nuclear and radiological emergency response (NERIS) and low dose risk research (MELODI), COMET will significantly aid preparation for the implementation of the Horizon 2020 umbrella structure for Radiation Protection. In close association with STAR and the ALLIANCE, COMET will take forward the development of a Strategic Research Agenda as the basis for developing innovative mechanisms for joint programming and implementation (JPI) of radioecological research. To facilitate and foster future integration under a common federating structure, research activities developed within COMET will be targeted at radioecological research needs that will help achieve priorities of the NERIS and MELODI platforms. These research activities will be initiated in collaboration with researchers from countries where major nuclear accidents have occurred. Flexible funds, unallocated to specific tasks at project initiation, have been included within the COMET budget to facilitate RTD activities identified through the JPI mechanisms developed that are of joint interest to the ALLIANCE, NERIS and MELODI. It will also strengthen the bridge with the non-radiation community. Furthermore, COMET will develop strong mechanisms for knowledge exchange, dissemination and training to enhance and maintain European capacity, competence and skills in radioecology. The COMET consortium has 13 partners, expanding from the organisations within the FP7 STAR project. In particular, COMET partners from countries which have experienced major nuclear accidents (i.e. Ukraine and Japan) and/or who hold Observatory sites.

The present invention provides a pulse wave velocity measurement method and system as well as an imaging device available for everyday use by general users at low cost with measurement accuracy less affected by posture or the like. The present invention simultaneously images different parts of a human body in a non-contact state by a single visible light camera and acquires continuous time series image data. Then, the present invention detects each pulse wave from the image data in the different parts of the human body based on a temporal change in pixel value of the different parts of the human body, and then calculates a pulse wave velocity of the human body based on a time difference between the pulse waves in the different parts of the human body.

University students show delayed sleep-wake patterns, i.e., later bed- and rise-times, and this pattern is known to be associated with various malfunctions. There may be a variety of daily activities associated with their delayed sleep patterns, such as watching TV. However, it is unclear to what extent each activity possesses an impact on their sleep patterns. The purpose of this study was to determine the daily activities associated with delayed bedtime in Japanese university students who live with or without their families. Three hundred and thirty-one participants were required to record the timing and duration of their sleep and daily activities, and the data from the 275 students (160 men and 115 women; 19.01 +/- 1.66 years) who completely filled forms were used for analysis. The results of multiple regression analyses suggested that interpersonal communication late at night is one of the major factors leading to the delayed bedtime of students living away from home. Among those living with their families, indoor activities such as watching TV and using the Internet were related to their delayed bedtimes. Attending classes and having a morning meal were related to the earlier bedtimes of the students living away from home, but there were no activities associated with those of the students living with their families. These results suggest that ensuring attendance at morning classes and having appropriate mealtimes, as well as restricting the use of visual media and socializing activities at night, are necessary for preventing late bedtimes in university students.

An object of the present invention is to provide a three-dimensional cam mechanism, which is capable of selecting a cam guide surface shape freely to drastically improve the degree of freedom for selecting a target locus on the follower side, transmitting not only a power between orthogonal axes but also a strong and reliable power, and performing a reversible operation. The present invention is configured such that a three-dimensional cam guide surface (2 (3)) is formed in a three-dimensional cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the three-dimensional cam (1) is translated into the swinging movement at the other end of the follower side link (4). As a result, the cam guide surface shape can be selected freely to drastically improve the degree of freedom for selecting the target locus on the follower side, and smooth operations of the three-dimensional cam can be obtained not only by the selection of the shape of a supporting member but also by the free design of the cam guide surface shape, without being neither limited to the power transmission between the orthogonal axes nor followed by the backlash.
