    This study aims to clarify the so-called “summarized captioning via computer assistance” in Japan. Summarized captioning [Youyaku-hikki] is an organizational activity that is planned and performed by volunteers. This activity is an essential service, particularly for people with hearing impairments. This study will first describe the general situation concerning PC-summarized captioning. Second, it will concentrate on the case of group A, which performs summarized captioning in City A. Further, it will clarify the problems encountered in PC-summarized captioning while discussing the activities and problems of group A.

    This study examined whether a letter prime presented in one modality facilitate a subsequent response to the same letter target presented in the other modality. A prime and a target were presented either in vision or touch. The task was a go/no-go task, in which subjects were required to press a key as quickly as possible if the target was either the letter L or T (go trials) and refrain from responding if the target was a 5-dot pattern (no-go trials). Results from two experiments showed facilitatory priming effects in both vision-touch (VT) and touch-vision (TV) modality pairs at both short and long target onsets. This suggests that the visuotactile crossmodal priming effects endure for a certain period of time and that tactile stimuli take time to be processed.

    We investigate a restoration process for a gray-scale pattern given by a snapshot of the Q-states ferromagnetic Husimi–Temperly model within a framework of a Bayesian inference. By using a generating function of path-integral representation, we derive an equation which describes the restoration process for the gray-scale pattern. We investigate two systems: system 1 in which the gray-scale value takes on {−1,−1+2/(Q−1),···,1−2/(Q−1),1} and system 2 in which the gray-scale value takes on {1,···,Q}. We find that there exists difference between Q=2 and Q≥3 as for behavior of the restoration process for the system 1.

    We study equilibrium states and their macroscopic uniformity in the fermion lattice system satisfying the assumptions presented by Araki and Moriya [5]. We show that every translation-invariant KMS state of the even part of the fermion algebra extends uniquely to a translation-invariant KMS state of the whole fermion algebra. The macroscopic uniformity is established for an extremal translation-invariant equilibrium state of the fermion algebra.

    Currently, faceted classification goes into the realm of the Internet “information retrieval” and it is more accepted as a tool outside the realm of the library and information science. Unfortunately, IT people have adopted the faceted classification without a methodologically full understanding of faceted classification. There is not much theoretical discussion about the possibility on the Internet environments based on its library original. In this paper, I will discuss the potential usage of faceted classification for “information retrieval” from a fundamental problem of relation of classification and searching/retrieval in an organic “information retrieval” system, which has much influence with changing from the library environments to the Internet environments. This change gives chances and challenges to faceted classification. With this change of environments, I want to argue that faceted classification keeps the merits of classification in information retrieval comparing with search engines and overcomes the problems with a traditional enumerative classification structure by providing for the flexible combination of terms to represent a specific complex/compound subject. Especially I want to argue that expressiveness of notation in faceted classification, which has been thought of as a defect until now, can find new usage as a potential switching/connection to multilingual information and a significant aiding in browse searching/retrieval and keyword searching/retrieval.

    We report some recent results and raise some open questions concerning Gromov-Hausdorff, variational and spectral convergence of finite networks endowed with the resistance metrics and measures, and also Royden’s compactification of infinite networks.
