The objectives of this study were to understand transition patterns and mechanisms of functional status, and to estimate active life expectancy (ALE) among senior citizens in a small town in Japan. With data drawn from surveys conducted annually from 1998 to 2002 (n=638 at baseline), prevalence and incidence of functional disability in activities of daily(More)
PURPOSE The number of pet dogs moving with their owners to Honshu, the main island of Japan, from Hokkaido, and the number of dogs imported from overseas were examined, and the possibility of invasion of Echinococcus multilocularis and E. granulosus with these dogs was discussed. METHODS The number of pet dogs moving to Honshu-island from Hokkaido was(More)

We focused on the epidemiology of alveolar echinococcosis especially in Japan and discussed control measures to prevent an epidemic. No effective control measures against alveolar echinococcosis have been identified thus far because it is difficult to fully understand the ecology of the parasite and its hosts, i.e. the precise infection route to humans. In(More)
We investigate robustness of correlated networks against propagating attacks modeled by a susceptible-infected-removed model. By Monte-Carlo simulations, we numerically determine the first critical infection rate, above which a global outbreak of disease occurs, and the second critical infection rate, above which disease disintegrates the network. Our(More)
Dementia is one of the common causes that lead to dependence of senior citizens in daily living. Clarifying the features of the elderly with dementia is instrumental in planning for their effective care and support in a community, and for attempts at prevention. Our purpose was to investigate the impact of sociodemographic factors among the elderly with the(More)
PURPOSE This article focuses on understanding epidemiological features of alveolar echinococcosis and discussing its prevention and control, especially from a viewpoint of the ecosystem and risk management. METHOD Publications on alveolar echinococcosis throughout the world were systematically reviewed with special reference to ecology, epidemiology and(More)
