In this study, social relationships between a robot and a person were categorized into four types consisted of two in the horizontal of social relationship （intimacy dimension） and two in the vertical of social relationship （status dimension）. In dialogue between humans and robots, the types of social relationship were adjusted by forms of language such as calling by name and speech styles. People＇s acceptance of robots was measured by people＇s comfortable approach distance to the robot. Participants showed greater acceptance of a robot when the robot called them by their names. In the case of speech style, participants accepted the robot which used honorific speech style without addressing them by their name, while they accepted the robot which used familiar speech style with addressing them by their name. There was an interaction effect between gender and calling by name.展开更多

What is interesting, the criterion for self-compactibility is not taken into consideration in commonly used self-compacting tests. On the basis of different tests concerning self-compacting concrete mixes, it has been found out that too high air content in their volume was the result of superplasticizer, in spite of meeting the self-compactibility criteria （i.e., self-venting）. For the decrease of too high air volume in SCC, the use of anti-foaming admixture （AFA） is proposed. As a result, the effect of AFA mix flow diameter is increased and the flow time is decreased. Moreover, the workability loss is lower. In case of mix incorporating AFA, their high flowability does not cause segregation of the mix, what is possible in case of SCC incorporating only superplasticizer. However, the time of the introduction of AFA and its type is essential to get higher flowability degree, but it is not important to achieve low air volume in SCC.展开更多
