国民健康・栄養調査の 2013 年と 2023 年について、20 歳以上の歩数・BMI・食塩・カリウム・エネルギーの平均(男女別)の差を、年齢ごとの値の差と、調査に答えた人の年齢構成の差に分けた(北川の方法・6 つの年齢区分)。 答えた人のうち 70 歳以上の割合はどの表でも増えた(歩数の表で男性 0.262 → 0.296)。その同じ年のとり方が、歩数では下が...
警察庁の「交通死亡事故の発生状況」の年齢層別・状態別の死者数と人口 10 万人当たりの死者数(2015〜2025 年・24 時間死者)で、交通事故の死者がどの年齢・どの移動の状態で減ったかを、人口の年齢構成の分と年齢ごとの率の分に分けて並べた。 24 時間死者は 4,117 から 2,547(0.619 倍)に減り、減った 1,570 のうち歩行中が 0.410、自動車乗車...
全国がん登録が公表する「死亡/罹患比(MI 比)」——その年にがんで亡くなった人の数 ÷ その年にがんと診断された人の数——が、何を表し、何を表さないかを確かめた。2023 年の MI 比を、同じ部位の 5 年相対生存率(2018 年診断)、期間法の 5 年と 10 年の生存率、登録の精度の指標と並べた。 表 8-A の MI 比は、人口動態統計の死亡数 ÷ 全国がん登...

同じ病気の論文を PubMed で調べるとき、言葉の選び方で件数がどれだけ変わり、それが何で分かれるかを、PubMed の E-utilities で取った件数と、PubMed が返した読み替えの式(2026 年 9 月 25 日・376 回の問い合わせ)で測った。 7 つの臓器で、ふだんの言葉(stomach・kidney・liver・lung・breast・bowel・pancreas)と医学の言葉(gastric・ren...
One word, precession, points at two different effects. One comes from fast motion itself, the other from the spacetime around a heavy body. Earlier papers treated the two separately, and none placed them in a single frame for comparison. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem...

That oil-drop charges are integer multiples of the elementary charge e is a classic piece of evidence for the quantization of charge. But do those data rule out smaller units such as half or a third of e? With the charges of 40 oil drops made by random numbers, the Euclidean algorithm, peak heights and counts of odd mu...

Paper 1056 and Paper 1057 measured that the fine-structure constant does not move with the units but moves with energy, and why it stops at low energy. Why, then, is there a quantity built from the same charge and the same Planck constant that does not move at all? This paper answers that. No new theorem or law is clai...

A tridiagonal matrix has n-1 entries off the diagonal, and in d dimensions the density exponent for which a shell’s mass does not depend on the radius is d-1. Both look like “one less”. This paper asks whether the two share a root. No new theorem and no new law is claimed. Scope of this paper (scope note): No new theor...
