    Background

    Mouthwashes play a pivotal role in oral care, and their efficacy has been explored extensively across various dimensions. As a contribution to the development of novel oral care products, this study aims to investigate the psychophysiological effects of aromatic mouthwashes during the resilience period from a short-term cognitive stressor utilizing biological signals and subjective evaluations.

    Methods

    A within-participant experimental design with 22 healthy females was conducted with four mouthwashes; peppermint (Mint), peppermint + bergamot (MB), peppermint + sweet orange (MO), and peppermint + lavender (ML), and water as the control (Ctl), after a 20-min calculation task. Subjective evaluations and physiological responses including skin conductance level and electrocardiogram were recorded throughout the experiment.

    Results

    Citrus mouthwashes (MO and MB) showed a greater decrease in heart rate and a significant increase in the high-frequency component of heart rate variability. The participants indicated a significant effect in terms of “flavor preference” and “refreshing sensation” for mouthwash use compared to the Ctl.

    Conclusion

    The results suggest that rinsing with citrus-flavored mouthwashes has a positive impact in alleviating the physiological stress response (in terms of cardiac activity). These findings may have implications for the development of innovative, novel oral care products that promote stress reduction and improve oral health.

    本研究の目的は,所望の未知情報に最適な構造を自動的に特定した上で構造的スパース性を活用できる方法を実現することである.2021年度は,本研究の第一段階として,構造的スパース性の最重要例であるブロックスパース性に注目して研究を行なった.既知の固定ブロック構造下でのスパース性はブロックごとのノルム和を抑圧することで効果的に促進できることが知られているが,本研究ではこのアイディアを発展させ,「ブロックごとのノルム和を最小にするブロック構造」を所望の未知情報に最適なブロック構造として採用することを提案した.さらに,膨大なブロック構造の候補から最適なブロック分割を見つける困難な問題を,大域的最適解を効率的に求めることが可能な凸最適化問題に帰着して解決することに成功した.この研究成果を纏めた論文は信号処理のトップジャーナル(IEEE Transactions on Signal Processing)に掲載されている.また,フェーズドアレイ気象レーダにおける構造的スパース性の活用法についても研究を行い,その研究成果を纏めた論文がリモートセンシング分野のトップジャーナル(IEEE Transactions on Geoscience and Remote Sensing)に掲載されている.圧縮センシングMRIに関する研究も行い,国際学会(European Signal Processing Conference 2021)でその成果を発表した.

    フェーズドアレイ気象レーダのデジタルビームフォーミング技術によるイメージングにおいて,通常,フーリエ変換に基づく,ビーム形成が用いられる.これが,レーダの空間分解能を規定し,通常,形成した所望方向から-3dBの点でレーダの空間分解能としている.この手法に対して,本研究では,気象レーダのような分散型ターゲットでは,ドップラー領域においてスペクトルが,風速によって移動する雨粒のレーダからの視線方向の風速付近に局在する性質を利用して,圧縮センシング技術を適用する手法を検討した.
    数値シミュレーションおよび実測データに基づく検討を行い,その有効性を検証した.これまでのビームフォーミング手法に比して,提案手法では少ないパルス数で,これまでの手法と同等の精度が得られることがわかった.さらに,ペリオドグラムは,提案手法において狭線化することが確認され,これは空間分解能が向上していることが示している.
    しかしながら,一方で,計算時間が必要なことから,提案手法はオフライン処理に向いていることも同時に示された.
    また,実測データにおいても空間解像度の向上が確認され,本手法の有効性が示された.

    本研究は,従来の標準的な最適化戦略で解決不能な「非凸型モデルで表現されたシステム同定問題」に対して信頼できる新解法を確立することを目標に据えており,特に,信号処理・制御工学等で重要な「入力信号に対して不連続な応答を有するシステム」に注目している.
    昨年度までの研究では,「一次元空間を定義域とする区分的連続システム同定問題」に対し,戦略的に設計した線形変換を用いることで,システムの出力信号に潜むスパース性が顕在化されることを明らかにした.また,この新たに発見されたスパース性を最大限に活用することで,信頼性の高い同定手法を実現している.
    本年度において,この研究成果を纏めた論文が信号処理に関するトップジャーナル「IEEE Transactions on Signal Processing」に採択され,提案法の有効性が国際的に認められることとなった.
    今年度の研究では,前年度に開発したスパース性顕在化と活用法のアイディアを「区分的定常プロセスの変化点検知問題」に応用し,音声セグメンテーション等を目的とした数値実験において提案法が既存法を著しく上回る推定精度を達成することを確認している.更には,制御工学分野における主要課題の一つである「離散・連続ダイナミクスが混在したハイブリッドシステム同定問題」等への応用を見据え,「多次元空間を定義域とする区分的連続システム同定問題」に取り組み,提案法の戦略を一般化することに成功している.この成果をまとめた論文は制御工学分野の主要国際会議(American Control Conference 2019)に採録が決定されている.
