The concealed information test (CIT) is an information detection technique measuring differential responses of the autonomic nervous system caused by the knowledge of crime-related information. The purpose of this study is to compare physiological responses caused by crime-related knowledge with those caused by a questioning voice with a deviant pitch in the CIT and to research whether there is any difference between these responses. Participants were assigned to one of three groups: a “knowledgeable” group, an “unknowledgeable” group, and a “deviant-sound” group in which the unknowledgeable participants received a deviant-sound question of a crime relevant item. Each participant chose one of the two envelopes that manipulate to assign the participant to the predetermined group. The envelopes for the knowledgeable group contained instructions with the role of the thief and the item related to the theft, and the envelopes for the unknowledgeable group and a deviant-sound group contained instructions with the role of the innocent. Participants are asked to hide their roles and undergo the CIT. The knowledgeable group and deviant-sound group showed increased electrodermal activity, low heart rate (HR) and low normalized pulse volume (NPV) for relevant items. In the deviant-sound group, there was no suppression of respiration, and low HR appeared earlier compared to the knowledgeable group. The differential responses on thoracic respiratory speed and HR were consistently observed across question repetitions in the knowledgeable group, while the differential responses on skin conductance response, HR and NPV decreased along with question repetitions in the deviant-sound group. The different patterns of differential physiological responses found in the knowledgeable group and the deviant sound group suggested the possibility of distinguishing these two groups. In particular, the suppression of respiration caused by the crime-relevant item may be characteristic of knowledgeable persons. The practical implications are discussed.

Icing is one of important problems that have to be prevented in jet engine of airplane. If thin ice layer deposited on the surface of blade is detached in fight, the debris is scattered and then impacts to a rear stage blade. Such impact of the debris could lead to catastrophic fracture of the blades. Numerical simulation is a powerful tool to understand how the icing is grown and detached. Thus, the icing phenomenon has been focused on the point of view from fluid mechanics. However, fundamental knowledge for mechanical property of ice itself and the adhesion of the ice layer is still very poor. The aim of this study is to examine about the mechanical property including Young's modulus, fracture toughness and adhesive strength at a low temperature. First of all, as a result of bending test on ice, it was found that the Young's modulus and fracture toughness of ice was increased as ambient temperature being low and loading speed being increased. Then, a shear force test was performed using ice/aluminum alloy to evaluate the interfacial fracture toughness as adhesive strength. As a result, the interfacial fracture toughness was decreased as ambient temperature being low and loading speed being increased. Based on those results, it is concluded that the mechanical property and adhesive strength are strongly affected by ambient temperature and loading speed.
