Aim: We conducted two studies to elucidate the relationship between heartbeat rhythms and relaxation among Japanese babies, young children, and their parents.Subjects and Methods: STUDY 1: Seven parents (age M = 34.3, SD = 5.5 years) with infants or toddlers (age M = 9.4, SD = 6.7 months) participated by listening to three conditions—a heartbeat sound, music, or music with a heartbeat sound—while completing a semantic differential exercise assessing musical imagery. Three types of music (classical, music box, and children’ s songs) were used. Image scores were compared among the three conditions in each type of music. STUDY 2: Participants included 161 parents who listened to three pieces of music, each with a different heartbeat rhythm (patterns A, B, and C). The parents reported their baby or child’ s responses to the music and also self-reported feelings they experienced. Finally, the parents indicated the piece of music they most preferred and related images using the SD exercise. To perform our analyses, we also assessed acoustic characteristics of the three heartbeat sounds.Results: STUDY 1: In the music arranged for a music box, participants evaluated musical imagery as significantly more “airy,” “comfortable,” “feels good,” “relaxing,” “easy,” “awake,” and “amusing” when listening to music with a heartbeat sound, in comparison to the other two conditions (p < .05). STUDY 2: “Rocking the body” and “heard quietly and slept” were the infants’ and toddlers’ responses to the music with a heartbeat sound. Fifty-six parents (34.8%) preferred “pattern A” music, 47 (29.2%) preferred “pattern B,” and 10 (6.3%) preferred “pattern C.” In analysis of “pattern A” acoustics, the mean number of heartbeats per minute, mean heartbeat frequency, maximum heartbeat frequency, and heartbeat Pitch Period Perturbation Quotient (PPQ) were 58/min, 120.3 ± 32.8 Hz, 248.4 Hz, and 11.39%, respectively.Conclusion: This research suggests that a heartbeat sound effective for relaxation has a rhythm of 60 beats/min, low-frequency bandwidth (120–220 Hz), and low percentage of PPQ. Our studies also indicate that music arranged for a music box with a heartbeat sound might be beneficial for inducing relaxation.

本研究は心音の脳波に対する影響を調べた.実験は、被験者白身の心音、彼らの母親の心音、他人の心音、雑音をランダムに提示し、その音源を聴取している時の脳波を測定した.またそれぞれの音源聴取後、アンケートを取り、その音源が、どれくらい心地良いか、眠気を誘導するか評価して貰った.測定した脳波との比較に用いた,脳波は、各音源聴取期間後半で高速フーリエ変換を行い、δ、θ、α、β、γの周波数帯域毎に平均周波数スペクトルパワー値及び各脳波測定電極間でコヒーレンスを計算した.その結果、パワー値に関しては脳波θ波が主に眠さ得点と相関がある事が明らかになった.一方、心音聴取時、聴覚野部位を含む脳波電極間のコヒーレンス変化が生じる事、その空間パターンは心音音源により異なる事が明らかになった.以上の結果は、私達は心音を区別出来、誘導する脳内情報処理が異なる事を示唆している.

北条市の水田で(瀬戸内平野部)1997年に緑肥レンゲをすき込み夏ソバを栽培したところ, 気象条件に恵まれ無施肥で250g / m^2を越える比較的高い収量が得られた.1998年には北条市と本匠村(九州中山間地)の水田で, 冬季休閑した休閑区とレンゲをすき込んだレンゲ区とを設け夏ソバを栽培した.北条市では, 播種期前後の多雨のため苗立ちが揃わず, 全般に生育も阻害され収量も低かった.この傾向は休閑区で特に著しく, 同区の収穫は皆無に近かった.しかし, レンゲ区では112g / m^2と前年の47%の収穫があった.本匠村では開花期以降の降水量が平年の2.76倍にも達し, 粒数不足のため収量は低く, レンゲ区で219g / m^2, 休閑区ではさらに低く143g / m^2であった.北条市のように生育初期段階に, あるいは本匠村のように開花期以降に土壌過湿仁おかれた場合でも, 夏ソバの生育阻害ならびに減収の度合いはレンゲ区の方が休閑区より少なかった.以上の結果は, 緑肥レンゲの作付けとすき込みが, 夏ソバ栽培にとって有効であること, 夏ソバの湿害を軽減する効果があることを示唆するものである.

生産物の品質、環境保全、安心安全な「食」情報に貢献する農業を展開するため、西日本で多くの面積を占める階段畑等のカンキツを対象とし、移動型選果ロボットを開発すると同時に、フィールドサーバおよび衛星画像等からの情報を表現できる2次元および3次元マッピング手法の開発を行った。これらの成果により、カンキツ生産における精密農業が推進されるものと考えられた。
