This study deals with transit tours focusing specifically on areas around airports that were previously ignored by tourists. Herein, with the aim of obtaining basic information for use in the revitalization of local economies, we clarified the relationship between an airport and surrounding areas through such a program. Specifically, through social media analysis, interviews, and questionnaires survey, we found a lack of collaboration between Narita International Airport Corporation, volunteer guides, and stores on Naritasan Omotesando Street. Our results showed that for transit tours to function more effectively as tools for revitalizing the local economy, these three parties need to coordinate their activities. Furthermore, we proved that an effort to create transit tours led by shops has the potential to overcome this lack of communication and improve cooperation between the involved parties.

Plasma formation and diagnostic techniques have been applied for diagnosis and non-invasive treatment of a breast cancer. A microwave CT (Computed Tomography) imaging has been proposed as a novel mammography technique without X-ray exposure and pain during diagnosis. For a practical application of the proposed mammography, a compact plain shape antenna with wide band characteristics had been invented and evaluated. Cytotoxic effects of atmospheric pressure gas plasma (AGP) irradiation onto breast cancer cells have also been experimentally verified.
