We conducted a self-administered survey to determine the patient’s sex and whether they underwent cancer screening in 2019, and if not, the reason for the same. The primary outcome measure was the percentage of people who did not undergo cancer screening.Results: A total of 198 responses (108 male respondents) were obtained. Among them, 189 were valid responses (valid response rate 94.5%). One hundred and twenty-nine patients (68.2%, 76 male) had not undergone screening. The most common reasons provided were “I have regular regular clinic visits and do not think they are necessary” (N = 65, 50.3%), “I underwent a gastroscopy within 2 years, a colorectal camera examination within a few years, and a chest radiography within a year” (42.5%), and “I have a separate complete medical checkup” (N = 15, 11.6%). Of the 65 patients who responded that their cancer screenings were unnecessary, 42 patients (64.6%) had not undergone a gastroscopy within 2 years, a colorectal camera examination within a few years, or a chest radiography or examination within a year.Conclusion: Roughly half of the respondents who did not undergo cancer screening elected to abstain because they believed that regular hospital visits were sufficient. Encouraging patients who regularly visit medical institutions to receive cancer screening is therefore necessary.Keywords: cancer screening, internal medicine, non-consultation, rural medicine

Reports on the use of a monoenergetic positron beam to investigate the state of interstitial oxygen in Czochralski-grown silicon (Si). Bulk value of Si; Source of stress in Si.

We fabricated a one-dimensional magnetophotonic crystal (MPC), in which a magnetic layer of Co–ferrite (∼40 nm in thickness) is sandwiched by a couple of dielectric multilayer reflectors with (SiO[sub 2]/TiO[sub 2])×7 structure. The Co–ferrite layer was synthesized by ferrite plating from aqueous solution at 90 °C. The MPC is so designed to enhance magneto-optical Faraday rotation θ[sub F] at the Fabry–Pe´rot resonance wavelength λ of the multilayer structure. θ[sub F] was observed to increase by factor of ∼5.4, but at λ=∼620 nm which is deviated from the target resonance (λ=740 nm) and at very weak transmissivity. This may be because the Co–ferrite layer is rough in surface and smaller in thickness than the target thickness at which Fabry–Pe´rot resonance is designed to occur. © 2000 American Institute of Physics.
