The purpose of this case study on the collaboration between citizens and experts, dealing with the future plan of the estuary weir of the Yoshino River is to understand how we can create renewed public knowledge for solving the social problems associated with science and technology as first step of the study. In order to analyze the case, the collaboration patterns were classified based on the condition of information/knowledge-sharing and the relationship between citizens and experts. The condition of information/knowledge-sharing was classified into two types as unshared condition or shared condition, whereas the relationship between citizens and experts was classified into two types as soft relationship (relationship of trust) or hard relationship (conflicting relationship). The process of collaboration was classified into four phases as making issues, forming hypothesis, confirming by experiment, and synthesizing and practicing future scenario. In addition, the utilization of the citizens' and experts' knowledge was analyzed based on a scheme applied Johari's Window. The results were as follows. a) The collaboration pattern between citizens and experts transformed itself as the process of collaboration made progress. b) The citizens' and experts' knowledge learnt in the past experience was utilized in order to make common context required for increasing mutual understanding of the issue. Based on these results, the conceptual model for collaboration between citizens and experts was discussed.

This study examined effects of a management strategy and of site selection process for high-level radioactive waste disposal on acceptance of siting repository in a German case. Data from 1,000 German residents, assigned by population composition ratio of 16 states, were collected in 2018 by internet survey. We considered evaluation of two policies: management strategy and site selection process. We also hypothesized own and national evaluations of the policies were relevant factors on the acceptance of siting repository. Results indicated that own evaluation of management strategy and site selection process directly had an effect on acceptance of siting repository, while own and national evaluation of management strategy had effects on own and national evaluation of site selection process, respectively. In addition, latent variables affected by the policies were different depending on which policy and/or which evaluation. National evaluations of both policies had effects on personal benefit, while own evaluations of both policies had effects on social benefit. Own evaluation of management policy had an effect on intergenerational subjective norms, while national evaluation of site selection process has an effect on stigma.

In order to evaluate the phenomena of masstransportation by groundwater flow in granitic media, it is necessary to make clear geological, hydrogeological and geochemical characteristics of fracture distributed in rock mass.Characteristics of fracture pattern, fracture filling material and alteration in Upper Cretaceous granite are investigated by core logging, mineralogical study, geophysical logging and hydraulic testing. This report describes the results which were obtained in the interval from the ground surface to 500m at Tono area in the central part of Japan.The results are summarized as follows ;(1) Fractures are classified into four groups on the basis of fracture pattern; Planar group (P), Irregular group (I), Curved group (C), and Stepped group (S).(2) Most of fractures belonging to P group and S group have filling materials composed of chlorite, calcite and sericite. Some of the fractures belonging to I group have been filled with materials composed of montmollironite, sericite and chlorite. Fractures of C group hardly have filling material.(3) Some of alterated fracture zones are consisted of P group fractures.(4) As a result of analysis on the fracture pattern and alteration pattern, three segments are recognized; Segment I (from 16.8m to 300m), Segment II (from 300m to 420m), and Segment III (from 420m to 500m). Especially, there are marked differences in fracture pattern and alteration pattern between Segment I and Segment III.
