The purpose of this study was to examine muscle activities during seven traditional different free dynamic exercises designed to strengthen the abdominal muscles. Eleven adult men with experience in weight training were asked to perform three repetitions of LSU, BSU, TSU, TC, RSU, LR and SLR. Activities of the upper rectus abdominis (URA), lower rectus abdominis (LRA), external abdominal oblique (EAO), and rectus femoris (RF) during the hip flexion and hip extension phases of each exercise were examined by electromyography (EMG) and analyzed using root mean square (RMS) values. The following results were obtained: (1) The mean RMS values for the URA were larger during the RSU and SLR than during the other five exercises. The value for the same muscle was larger during the TC exercise than during the LSU, BSU, TSU, and LR exercises. The mean RMS value for the LRA was largest during the RSU exercise, while that during the SLR exercise was larger than those during the LSU, BSU, TSU, TC, and LR exercises. (2) The mean RMS value for the EAO was largest during the SLR exercise, while that during the RSU exercise was second-largest and that during the TSU exercise was third-largest. The mean RMS values for the RF were larger during the RSU and SLR than during the other five exercises. The smallest value for this muscle was recorded during the TC exercise. (3) In most of the exercises, RMS in the hip flexion phase was larger than in the hip extension phase, and each muscle exhibited a knee flexion phase/knee extension phase ratio of between 0.5 and 0.8. However, the ratio for EAO and RF exceeded this range. (4) The muscle activity for the RF muscle in the RSU and SLR exercises was large, implying excessive stress for the lumbar vertebrae. Nevertheless, these exercises induced active muscle activity, and appeared desirable to perform with sufficient attention to safety.These results suggest that RSU and SLR exercises are the most effective movements for stimulating the URA, LRA and EAO. Moreover, TC is an effective movement for training the URA, and TSU is an effective movement for training.

京都豊年踊りとは、天保10年(1839)3、4月京都市中におこった熱狂的な踊り現象をさす。本稿では、この豊年踊りの絵画資料を概括し、その伝播過程や絵画の共通性や特異性を検討する。まず木版刷りの史料を検討した。京都で発行された一枚刷り「豊熟都大踊」「みやこおどり 鈴なるこの神徳」(大阪府立中之島図書館)や木版本『町々吉兆都繁栄』(早稲田大学附属図書館)は、この踊りの情報を各地へ伝える役割をはたした。たとえば後者は、『天保雑記』(国立公文書館内閣文庫)や『藤岡屋日記』(東京都公文書館)にそのまま書写されている。次に図巻・屏風の資料を検討した。図巻としては、「蝶々踊図巻」(大阪歴史博物館)と「天保十年豊年踊図巻」(チェスター・ビーティ・ライブラリー、アイルランド共和国ダブリン市)が双璧をなす。また「天保踊図屏風」(京都市歴史資料館)について、写真をかかげ、関連史料と合わせて紹介した。最後に冊子のさし絵を検討した。なかでも「天保視聴記事」(愛知県西尾市立図書館岩瀬文庫)のさし絵は図巻に匹敵し、『天保踊之記』(愛知県大洲市立図書館矢野玄道文庫)は、踊りに使われた衣装や提灯・手燭を図入りで説明している。これらの資料は、文字資料(文書・記録)とあわせて、豊年踊りの実状を詳細に明らかにするであろう。

集中治療室(ICU)では,時間経過とともに刻々と変化する病態に合わせた薬物治療計画が必要である。そのため,薬剤師による迅速な薬学的介入は重要であると考えられる。今回,ICU専従薬剤師による全身管理への薬学的関与の影響について検討した。方法:那須赤十字病院ICUへ入室した患者を対象とした。2010年1月から12月の270名を専従前群,2013年1月の49名を専従後群とした。薬剤管理指導記録から薬学的介入の内容,薬物治療変更の有無について比較検討した。結果:薬剤管理指導実施率は専従前64.1%から,専従後91.8%へ有意に増加した。薬学的介入による薬物治療変更は,専従前51.3%,専従後73.2%へ有意な増加を認めた。考察:ICUへの薬剤師専従化により,薬学的介入件数,薬物治療変更率はともに増加した。これより,患者の病態変化に合わせた迅速な薬学的介入を行うことができた。

The purpose of this study was to investigate the muscle activation levels of the hip muscles duringpitching motion as ball speed was increased. Six college baseball pitchers were participated in thisstudy. Surface electromyography data were recorded in pivot leg from 6 muscles : adductor longus(AL), gracilis (GR), adductor magnus (AM), rectus femoris (RF) , biceps femoris (BF) and gluteus medius(GM). The pitching motion was divided into 5 distinct phases: wind-up, early cocking, late cocking,acceleration, follow-through. The results demonstrated that high level muscle activity (greater than 40%maximal voluntary contraction) was found in GM during early cocking phase, and in AL, GR, AM andBF during late cocking phase, and in AL, GR and BF during acceleration phase. Then, the activity levelof the hip muscles in the slow ball pitching and fast ball pitching was compared. Significantly highermuscle activity was showed in fast ball pitching in AL, GM, and BF during early cocking phase, in BFand AL during late cocking phase, and in AL, GM, and RF during acceleration phase. The findings fromthis study indicate that high muscle activity have been shown in the abductor of the hip joint duringearly cocking phase that produce translational movement, and high muscle activity have been shown inthe adductor and extensor of the hip joint during late cocking phase and acceleration phase that producerotational movement.

To compare the effectiveness of five different muscle training movements on the biceps brachii, latissimus dorsi and trapezius muscles, eight weight-trained men (age, 20.4±0.5 years) were asked to perform three repetitions, at 70% one repetition maximum, of upright rowing (UR) and bent-over rowing (BR) exercises using a barbell ; and seated rowing (SR), front lat pull-down (LPf) and back lat pull-down (LPb) exercises using a Universal Machine. The activities of the biceps brachii, latissimus dorsi, and trapezius during the elbow flexsion and elbow extension phases of each exercise were analyzed using integrated electromyography (EMG) and normalized I-EMG. The results were as follows :1. The mean nrmsEMG values for the biceps brachii were larger during UR and LPf exercises than during BR, SR, and LPb exercises, suggesting that UR and LPf are more effective than the other movements for training the biceps brachii. The mean nrmsEMG values for the latissimus dorsi were larger during SR, LPf, and LPb exercises, followed by BR and UR exercises (in descending order), suggesting that SR, LPf, and LPb exercises are more effective than the other movements for training the latissimus dorsi.2. The mean nrmsEMG values for the upper trapezius were larger during UR and BR exercises than during SR, LPf, and LPb exercises, suggesting that UR and BR exercises are more effective than the other movements for training the upper trapezius. The mean nrmsEMG values for the middle trapezius were larger during BR and SR exercises than during UR, LPf, and LPb exercises, suggesting that BR and SR exercises are more effective than the other movements for training the middle trapezius. The mean nrmsEMG values for the lower trapezius were larger during BR exercise than during other movements, suggesting that BR exercise is more effective than the other movements for training the lower trapezius.3. In all the exercises, each muscle showed a higher nrmsEMG value during the elbow flexsion phase than during the elbow extension phase. This observation suggests that the training method examined in this study should emphasize the elbow flexsion movement.The present results suggest that UR exercise is the most effective movement for training the biceps brachii and upper trapezius, BR is most effective for training the upper trapezius, middle trapezius and lower trapezius, SR is most effective for training the latissimus dorsi and middle trapezius, LPf is most effective for training the biceps brachii and latissimus dorsi, and LPb is most effective for training the latissimus dorsi.

<p> 本研究では投球速度の異なる野球投手の筋厚を比較し、高い投球速度を示す投手の形態的特徴を明らかにすることを目的とした。2016、2017年の春季オープン戦に登板した投手を対象に全投球の球速上位20%の平均値を算出し、140km/h以上を高速群(n=7)、130km/h未満を低速群(n=9)として抽出した。筋厚測定には超音波診断装置を使用した。撮像部位は両側の前腕部、上腕部(前・後部)、胸部、腹部、側腹部、肩甲棘部(上・下部)、肩甲骨内側部・肩甲下部、腰部、臀部(後・側部)、大腿部(前・後部)、下腿部(前・後部)であり、これらの17部位より29筋を測定の対象とした。部位別の比較において高速群では投球側の前腕部、腰部、臀部、大腿後部、下腿後部、非投球側の腹部、側腹部、大腿前部、臀部、大腿後部、下腿後部において低速群よりも高い筋厚を示した。また、筋別の比較において高速群は投球側の脊柱起立筋、大殿筋、大腿二頭筋、腓腹筋、非投球側の腹直筋、内腹斜筋、脊柱起立筋、大腿二頭筋において低速群よりも高い筋厚を示した。これら結果より投球速度の高速群では体幹、下肢筋群の発達が顕著であることが示唆された。</p>

カラー画素をマトリクス状に配した画像表示装置の解像度に関する表示特性の評価は, 固体撮像素子のように単にサンプリング定理での解釈だけでは済まず, 人間の目の視覚特性を取り入れて一緒に考えなければならない.本論文では, 3種類のカラー画素配列について, それぞれの画素逆格子による表示ナイキト限界を導入した後に, 静止画および動画表示における2次元視認解像度限界を主観評価で定量的に求め, カラー画素配列の評価を行っている.まず静止画表示では, それぞれが静止した白黒正弦波および単色正弦波を表示したときの2次元視認解像度限界を, 多数の被験者によるシミュレーション画像の主観評価から求め, 表示ナイキスト限界との比, すなわちケルファクタともいうべき解像度限界係数を求めた.その結果, 白黒表示ではその限界係数は約0.6〜0.7で, 単色表示ではそれは約0.5〜0.6であった.また3種類のうち, 総合的にデルタ配列が最も優れていると評価された.一方, 動画表示では, 定速度で水平, 斜め, 垂直方向に動く白黒正弦波パターンを表示したときの視認解像度限界を同様にして求め, この種の表示装置の動画表示における視認解像度特性と動きの速度, 画素配列との関係について検討した結果, どの画素配列においても, 最適速度で一般にその視認解像度限界は, 静止画表示と比べ, 最大約10%〜20%の改善をしていることを明らかにした.
