This report concerns with the recognition memory and the confidence rating. The hit ratio was correlated to the confidence ratings, while the correct rejection (CR) ratio was not correlated to the confidence ratings. Especially, in case of short presentation of target items, negative coefficient was observed between CR and its confidence rating. This is because there were no memory traces of new items, so subjects used supplementary information about those items that had no relations to experimental learning episodes, and the subjects used that information as clue in recognition judgement. Although the base of the confidence rating was relpaced by the plausibility of such information, the subjects could not monitor the source of confidence.

Wave focusing has been attracting ocean engineers as one of the most promising techniques to control ocean waves. It creates a calm sea area and helps efficient utilization of wave energy. In the present work, a hydrodynamic singularity distribution which expresses a wave focusing lens is derived by the method of matched asymptotic expansion, assuming slenderness of the lens and high frequency of incident waves. The singularity distribution gives the following necessary conditions for scattered waves in each section of the lens : there is no reflection from the lens and the transmitted waves suffer a phase shift in passing the lens. The phase shift is given by the wavenumber and the distance between the section and the focus. From these conditions, we examine a sectional shape of the lens and determine the whole geometry.It is shown by experiments and numerical computations using the two dimensional doublet distribution method that a submerged chevron shape plate, which is suitably folded, scatters a wave system which satisfies the above conditions at a certain wave frequency, but not in wide band of wave frequencies because of dispersion of water waves.Then it is shown by experiments that a certain number of submerged circular cylinders, which are horizontally arranged at intervals just like a raft, transmits waves which have enough phase shift to focus waves but reflects almost no waves in wide band of wave frequencies.Finally, we examine performances of three types of lens, namely, submerged flat plate, submerged chevron shape plate, and submerged circular cylinders, in both regular and irregular waves. It is shown by numerical computations that the wave focusing efficiency of the lens consisting of circular cylinders is about twice that of the flat plate type lens and that the drift force acting on the former is less than half of that on the latter in irregular waves.

The pore structure of concrete is highly complex and random. Fractal theory is used to describe the characteristics of its pore structure. Ds (surface fractal dimension) is commonly used to characterize the surface roughness of the pores. However, the existing Ds model is limited to two dimensions and there are unreasonable assumptions about the shape of the pores and the method of measuring pores is not applicable. Therefore, this paper proposes a three-dimensional (3-D) model for calculating the Ds. The new parameter Dss represents the chaotic degree of element morphology in the 3-D pore system. When Dss=0, the pore morphology tends to be the same. The larger Dss value is, the more divergent and diversified pore morphology is. The specimens in two states of standard curing and high temperature drying were prepared and the pore structure parameters of the specimens were calculated by combining CT scanning, Deep Learning and 3-D reconstruction. By comparing Dss and Dv (volume fractal dimension) and other parameters, it is found the 3-D pore system of concrete is more chaotic and becomes more complex under the effect of high temperature drying. It also confirms the reliability of the 3-D fractal dimension model proposed in this paper.

The aim of this study, as a case study of college football short-term tournament, was to clarify the practical wisdom related to member selections in team sports. The participant is a head coach of a men’s university football team in Japan. After the short-term tournament, a dialogue was held by the second author with head coach. Group interviews consisted of focus group basis for 5-6 players. Audio data obtained by the interviews were converted to the text. This was followed by discussions among the head coach and co-authors for phenomenological reflection. The results highlighted two practical wisdoms in the coaching scene that are “management for players’ motivation” and “maintenance of team functionality”.

From the Heian period on, we observe many examples of funereal ritual in which the corpse was moved to religious facilities, like Buddhist temples. In many of these cases, the corpse was removed in the same manner as removing living persons. The research to date on the subject has termed such activity "heisei-no-gi" and "nyozai-no-gi" and has interpreted its purpose as an attempt to veil the manifestation of impurity arising from death. However, due to both the limited timeframe and material dealt with in the research literature, its conclusions lack sufficient historiographical confirmation, showing that they have been built on a fragile edifice of mere supposition and conjecture. Given such a situation, the author of the present article, referring to the way in which corpses were moved as "heisei-no-gi" citing cases from the 10th century to 16th century, proceeds to identify the very first requirement and the accepted condition through that age. He then points out that while "heisei-no-gi" was a part of funereal procedures, it was a unique practice existing apart from funereal ritual per se. First, as to the purpose of "heisei-no-gi" in terms of its most fundamental meaning, an examination of its relationship between "heisei-no-gi" and ritual impurity shows that even in many cases where "heisei-no-gi" is evident, ritual impurity still occurred, thus proving the conventional interpretation of veiling ritual impurity untenable. Next, the author argues that in funereal rites per se, fear and affright of possibly leading a person to his eventual death would exist, and, therefore, "heisei-no-gi", which was apart from funereal ritual per se, was a device for avoiding that kind of fear and affright. And so the necessity to remove the corpse in a non-funereal manner, by treating it as if it were still alive, gave rise to the practice known as "heisei-no-gi".
