A summary of 2025 (2025年の総括)

 

2025年は,以下の論文発表を行いました.自由外出マスク(PAPR for Everyone)を主軸として,AGI(汎用人工知能)の問題,特に,民主主義の防衛に関して,論考を進めてきました.(投稿中の論文多数.) また,浮上質量法(Levitation Mass Method)の総括も始めました.


In 2025, I published the following papers. Centered on the concept of the Freedom-of-Movement Mask (PAPR for Everyone), I advanced a series of studies on artificial general intelligence (AGI), with particular emphasis on the defense of democracy (with many additional manuscripts currently under submission). In parallel, I also initiated a comprehensive synthesis of the Levitation Mass Method.

研究プロジェクト 電動ファン付き呼吸用保護具をロックダウン代替手段として活用した社会技術システム(第一報)

社会安全とプライバシー, Vol.9, No.1, pp.1-17, 2025.

要旨:本研究は,COVID-19 以降に提起された「ロックダウンの社会的損失を最小化しつつ空気感染症を抑制する代替手段」を,再現可能な工学的システムとして提示することを目的とする.著者らはこれまで,市民利用を前提とした電動ファン付き呼吸用保護具(PAPR)の概念提示,流体力学モデルに基づく呼吸流量・漏れ推定法,マイクロコントローラとスマートフォンを連携した装着状態の可視化技術,さらに国際共同研究による低コストPAPR試作と現場運用評価に取り組んできた.本論文は,これらの知見を基盤として,採択された科研費(基盤研究B)における研究計画を開示するものである.具体的には,(1)一般市民向けPAPR本体と評価装置群の体系的開発,(2)装着率ネットワーク管理システムの設計,(3)地域社会での小規模社会実験による実効性・受容性評価を柱とする.現段階では未完成の計画段階であるが,社会的自由と感染制御の両立を目指す工学的アプローチの射程と課題を明確化する点に,本研究の意義がある.

A look towards 2026 (2026年に馳せる決意)

 

2026年は、採択された科研費・基盤Bの研究計画に基づき、「次のパンデミックから人類を救う」ことを目標として、PAPR for Everyoneコンセプトに基づく,自由外出マスク(Distancing-Free Mask)の研究開発を推進する。2025年には,PAPR for Everyoneコンセプトの実現可能性に関する論文(上記(1)),装着状態ネット管理システムの試作に関する論文(上記(2)),呼吸を楽にする圧力逆制御を目指した検討(上記(3)(4)),ネット管理システムのプライバシ保護法に関する論文(上記(5) (6))を一流誌に発表しており,本構想の学術的妥当性は認められてきており,実用化検討の段階に入っていると考えている.このコンセプトは,一たび,社会に一度受け入れられれば、巨大な社会インフラになりえる。その実現に向け、国際トップジャーナル,一流メディアでの発信を目指す。出資者を募り,実用化を目指したい.

同時に、AGI(汎用人工知能)が生み出す課題,その中で,特に,人類の尊厳ある存続,民主主義の防衛,という課題は、「AGI時代において,人類を救う!」を目指しており,社会的インパクトの大きさにおいて最上位に位置し、研究者として最も強いやりがいを感じている領域である。トップジャーナル,主要メディアでの情報発信を通して,この問題での貢献を目指す.上記論文(8)での問題設定を起点として,既に,著名誌数誌に,いくつかの角度からの解決案を論文投稿している.

また,e自警ネットワークの発展版コンセプト(Fully Monitored Public Space (FMPS))の研究・開発を進める.Fully Monitored Public Space (FMPS)も,社会に受け入れられれば,巨大な社会インフラの出現に繋がる.FMPSにおけるプライバシー保護の決め手として,上記論文(5)(6)で提案しているVerifiable Record of AI Output(VRAIO)を適用する.

さらに、元々のメインテーマである浮上質量法(Levitation Mass Method)の体系的総括を進る.まず,上記論文(8)を発展させる形で,Dynamic Force Calibrationの確立に向けた道筋をつけることを目指す.

 

In 2026, based on my research plan for the adopted KAKENHI Grant-in-Aid for Scientific Research B, I aim to advance the research and development of the Distancing-Free Mask under the PAPR for Everyone concept, with the goal of "saving humanity from the next pandemic." In 2025, I published papers in top-tier journals on the feasibility of the PAPR for Everyone concept (item (1)), a prototype of the networked management system for mask-wearing conditions (item (2)), studies on pressure-reverse control to facilitate breathing (items (3) and (4)), and privacy protection laws for the networked management system (items (5) and (6)). The academic validity of my concept has been increasingly recognized, and I believe it is now entering the phase of practical application. Once accepted by society, my concept has the potential to become a massive social infrastructure. To achieve this, I aim to disseminate my work through top international journals and leading media, while seeking investors to pursue practical implementation.

Simultaneously, I address the challenges posed by AGI (Artificial General Intelligence), particularly those related to ensuring humanity's dignified survival and defending democracy. This pursuit, aiming to "save humanity in the AGI era," holds the greatest social impact and is the most rewarding field for me as a researcher. Through publications in top journals and major media, I seek to contribute to this issue. Building on the problem framework I established in paper (8), I have already submitted several solution proposals from various perspectives to prominent journals.

Additionally, I will advance the research and development of an evolved version of my e-Vigilance Network concept, termed Fully Monitored Public Space (FMPS). If accepted by society, my FMPS could lead to the emergence of another massive social infrastructure. As a key mechanism for privacy protection in FMPS, I will apply the Verifiable Record of AI Output (VRAIO) I proposed in papers (5) and (6).

Furthermore, I will continue the systematic consolidation of my original main theme, the Levitation Mass Method. Specifically, by building on paper (8), I aim to establish a pathway toward the development of Dynamic Force Calibration.

 

新年を迎え,この1年間の研究方針について考えてみました.社会の役に立てるよう,最大限の努力をもって研究を進めていきたいと思います.

As the new year begins, I have reflected on the research direction for the coming year. I am committed to advancing my research with utmost effort to contribute to society.

新年にあたり,皆さまと,皆さまのご家族の,ご健康とご多幸を,心よりお祈り申し上げます.
I wish you and your family will have a healthy and happy new year!
