Carp has been used as food for special occasion in Saku City, Nagano Prefecture. In our previous study, young people said the carp meat had a muddy odor or fishy smell. Therefore, the weak-point of carp is its taste and odor. In order to better utilize carp meat as a foodstuff the taste and odor was analyzed. In this study, the odor differences between raw and frozen carp meat were measured by a sensory evaluation and instrumental analysis. In addition, the odor differences due to the different parts of the carp meat were measured by instrumental analysis. The samples were subjected to sensory evaluations of odor by 22 trained panelists (ave. age was 23.4). And Multi Organoleptic System was used as an instrument for analysis. As the results, the analysis found the frozen sample was less odorous than the raw sample. In the raw sample, the odor was strongest closer to the head. Thus, considering which part of the carp body the meat came from is important. It was shown that frozen processing is useful to reduce raw and fishy odor.

Many of elderly people are not good at operation of PC with mouse and keyboard, because they need more time to experience to get enough skill. Through the observation to them in PC school, their characteristics are different from the younger people's movements. In this study, the difference of mouse operation between elderly people and younger people became clear by measurement of mouse movement. Mouse rotation in the horizontal pointing operation can make some difference among them. The volume of acceleration to the target would be the cause of the difference. From the result, we can find out the needs for development of mouse movement system which consider the elderly people's operation characteristics.

Helminth parasites, 11 species of trematodes, 4 species of cestodes and 6 species of nematodes, are described from marine planktonic invertebrates collected in Japanese waters and the East and South China Seas. The trematodes are: a Guschanskiana sp. Metacercaria (Accacoeliidae) from Sagitta enflata; Tetrochetus sp. Metacercariae (Accacoeliidae) from S. enflata, S. macrocephala and Sagitta sp.; Accacoeliidae gen. sp. metacercariae I, possibly of the genus Accactadium, from S. crassa f. naikaiensis, S. enflata, S. hexapera, S. macrocephala, Sagitta sp. and chaetognaths; Accacoeliidae gen. sp. metacercariae II from S. crassa f. naikaiensis; an Accacoeliidae gen. sp. metacercaria III, perhaps belonging to the genus Accacladocoelium, from S. crassa f. naikaiensis; Tergestia sp. metacercariae (Fellodistomidae), probably of T. laticollis (Rudolphi, 1819) Stossich, 1899, from S. crassa f. naikaiensis; Lecithocladium sp. metacercariae (Hemiuridae), possibly of L. excisum (Rudolphi, 1819) Lühe, 1901, from S. enflata, S. nagae and Sagitta sp.; a Parahemiurus sp. metacercaria (Hemiuridae) from a chaetognath; Hemiuridae gen. sp. metacercariae, related to the subfamily Dinurinae, from heterokrohnia sp., Sagitta sp. and chaetognaths; metacercariae of Pseudopecoelus japonicus (Yamaguti, 1938) von Wicklen, 1946 (Opecoelidae), from Euphausia similis; and a Paronatrema sp. metacercaria (Syncoeliidae) found free in a plankton haul. The cestodes are: Echinobothrium sp. larvae (Diphyllidea: Echinobothriidae) from Leptochela sp. pasiphaeids; Scolex pleuronectis Mueller, 1788 (Tetraphyllidea), from Sagitia sp.; Phyllobothriidae gen, sp. larvae (Tetraphyllidea) from Eukrohnia hamate and S. crassa f. naikaiensis; and larvae of Pseudonybelinia odontacantha Dollfus, 1966 (Trypanorhyncha: Tentaculariidae) from Euphausia recurva. The nematodes are: a larva of Anisakis sp. larva (Ⅰ) of Berland (1961) (Ascaridoidea: Anisak idea) from Euphausia nana; and Thynnascaris spp. larvae (Anisakidae) classified into five different types from S. crassa f. naikaiensis, S. nagae and Calanus sinicus. The metacercarial development including progenesis in E. similis and the life cycle of P. japonicas are discussed. The systematic position of P. odontacantha is discussed, and a diagnosis of the genus is given. A list of some other helminth or metazoan parasites obtained is appended.
