Abstract
It is important to focus on automatic and intuitive
information processing style which have received little
attention in information provision on environmental
issues. This study aims to reveal effects of information
provision through narratives on behavioral intentions andpolicy acceptance about environmental issues. Results
show that narrative information leads to higher behavioral
intentions and policy acceptance than logical information,and this tendency is more pronounced when people havelittle interest.
This work aimed to develop the framework to performparameter estimation effectively for probability
distribution functions relevant to reliability and safety.
This framework is designed to make estimation with
sufficiently high accuracy even for small number ofobservations. In addition, the estimation is alsosufficiently robust under the considerable uncertainty.
The sequential Bayesian inference and the effective use ofprior information were investigated in this work to
propose the newly developed framework. This framework
was applied to real cases to see its effectiveness and futurechallenges.

period of one-week. In the estimation of ambient air
concentrations, we confirmed that the model simulationfits well for many substances with high PRTR emissions,and we identified the substances for which backgroundconcentration correction is effective.

physics and system-level model from a perspective on risk
model from a perspective on risk
through spacecraft system life cycle was constructed,
through spacecraft system life cycle aiming to improve the efficiency of risk assessment andrationality of risk treatment for spacecraft systems. The
effectiveness of the proposed framework was confirmed
by applying it to the spacecraft system, and also by
applying it to the hydrogen refueling station, which is also
an advanced engineering system.

The objective of this research is to advance the risk
analysis of energy systems using model-based risk analysis
based on the Physics model, which enables the physicaland dynamic properties of the system to be obtained. The
research advances the risk analysis which is carried out
continuously from the design and development stage tothe operation stage of each energy system (production,storage, utilization equipment, etc.) of a decentralizedenergy system for sustainable energy utilization.
Radiography has been widely used in fields such as nondestructive testing for medical diagnostics or research anddevelopments and radiation monitoring fordecontamination work in nuclear power plants. Recently,
thick film scintillators with a few tens of micrometers
thickness can improve the sensitivity and resolution inradiation detection and imaging. In present study, thickfilm scintillators were prepared by high-speed chemical
vapor deposition and their scintillation properties wereevaluated.
