I used the fecal analysis to examine the food habits of the raccoon dog Nyctereutes procyonoides
living at Tsuda University’s Kodaira Campus, a green space surrounded by an urbanized area. The
campus is dominated by a Quercus myrsinifolia forest planted 90 years ago; because of the darkness of the copse, the shrubs and herbaceous plants which typically compose the raccoon dogs’ diet are scarce. A total of 109 fecal samples were analyzed using the point frame method. There were clear seasonal changes in the fecal compositions: various items like fruits and leaves appeared in late winter; insects and mammals increased in spring; insects and leaves accounted for the contents of most of the summer samples; fruits and seeds were dominant in autumn; and various items appeared again in early winter. Particularly important fruits were those from trees such as Aphananthe aspera and Diospyros kaki, while shrubs and forbs, which are generally thought to be important foods for the raccoon dogs living in similar habitats, actually accounted for only a small part of the sample. An important finding was that although the campus was located in an urbanized area, man-made materials were not important as food sources for the raccoon dogs.
Human communication is inherently multisensory. This property has been applied to accessible
information systems via a human voice using the multimedia DAISY, and the information transmitted can be understood by many people. However, a part of persons with neuropsychological impairments with auditory-recognition difficulties cannot identifyreal voices. The clues for understanding the information remain unclear, and the true accessibility of transmitting information is not fully realized. I prepared parts of a picture book, sentences and illustrations of disaster-information, and combinations of both in a multimedia DAISY format, and asked if the persons could identify them. Although all subjects understood the book and the information combined, persons with non-impairments as well as those with heavy impairments used the sentences as clues to understand the information, and those with mild impairments used the illustrations. Most of the subjects understood speaking from a real person. The multisensory integration worked in a different manner between the multimedia DAISY and humans. It is important to understand the difference between the systems of the format and the human brain. However, the possibility of transmitted information in this format, being easy to control, is useful for improving the accessible-information transmission processes.
