Method: A group with ADHD-I (n = 16) and a paired control group (n = 21) completed a battery of tasks covering the major domains of EF (planning, working memory, flexibility and inhibition) and non-EF (alertness, divided attention, flexibility, sustained attention, visual field and visual scanning). Results: EF impairments in planning, spatial working memory, flexibility, and inhibition as well as non-EF impairments in divided attention, flexibility, sustained attention and visual scanning were observed in the ADHD-I group. Conclusion: Our results do not support the traditional model of ADHD. Given that neither EF nor non-EF tests typically distinguish ADHD-I from ADHD-C, alternative methodologies are required to confirm the validity of ADHD subtypes in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition.展开更多

Initialty, we abstract annuat data on Land and buildings usage within a radius of 0 m-400 m for railway stations and 400 m-800 m for subway stations in Fukuoka, Japan by using the GIS. We then analyze the relationships between 13 factors of rand use and 8 factors of building usage, as well as the related poputation, Land price, and passengers using the quantitative expression method. Using several categories of land use and building usage as explanatory variables, we anatyze the degree to which the selected categories affect population, Land price, and passengers by using the muttiple regression method. This research can aid the further development of land and buitding usage in the future.展开更多

However, urban spaces are packed with visitors on festival days, thus affecting accessibility to pedestrian spaces. This research examined visitor satisfaction with accessibility to pedestrian spaces during special events such as festivals. We particularly focused on the Hakata Dontaku festival, which is celebrated in Fukuoka, Japan. We studied three main elements that affect pedestrian satisfaction and perceived accessibility through walking, namely, safety, mobility, and amenities. We first analyzed previous studies and employed analytical hierarchy process to setup indicators for satisfaction measurement. Second, we determined visitor satisfaction through a survey questionnaire, which was conducted during the Hakata Dontaku festival. Third, we assessed the normality of the data set that was obtained from the questionnaire. Finally, we applied structural equation modeling. Results showed that the proposed model was a good fit, as indicated by the goodness of fit test, and the majority of indicators loaded significant values that supported their constructs. Satisfaction with amenities was found to be the most statistically significant variable that influences visitors' perceived accessibility during the Hukata Dontaku festival展开更多
