Title Alternative	Study on Physical Activity Levels During Soccer Matches Among Junior High School Students Focusing on Position and Physical/Fitness Characteristics
FullText URL	cted_016_061.pdf
Author	NATSUMEDA, Takaaki\| ADACHI, Minoru\|
Abstract	中学生34人を対象とし，身体・体力特性とサッカー試合中の身体活動量について，ポジションに着目して比較・検討した．その結果，身体・体力特性についてはポジション間に有意な差は認められなかった．歩数ではポジション間で有意差が認められ，ライトサイドバックが少なく，センターミッドフィルダーが高かった．強度別身体活動量時間の割合ではポジション間で有意差が認められ，ライトサイドバックが低く，センターミッドフィルダーが高かった．以上のことから，本研究の対象中学生ではポジション間で身体・体力特性には有意差が認められないが，サッカー試合中の身体活動量ではポジション間で差が生じることが示唆された．

小学生の学校生活における身体活動量と体力に関する研究

JaLCDOI	10.18926/CTED/70359
Title Alternative	Physical Activity and Physical Fitness in the School Life of Elementary School Children
FullText URL	cted_016_045.pdf
Author	YASUNOBE, Jin\| SASAYAMA, Kensaku\| ADACHI, Minoru\|
Abstract	本研究の目的は，小学校6年生の学校生活における活動場面別の身体活動量を加速度計を用いて客観的に測定し，その体力との関係を検討することである．対象は小学校児童85名(男子41名，女子44名)とし，休み時間，体育授業，学校生活全体における歩数と強度別活動時間を評価した．その結果，男女ともに体力上位群は休み時間において歩数とMVPAが多い傾向が示され，特に男子は中休み，女子は昼休みおよび体育授業で有意差が認められた．各活動場面のMVPA が占める割合は休み時間11.3％，体育授業15.7％であり，諸外国と比較して少なく，国際的推奨値にも届かなかった．本研究は，小学校における身体活動量の基礎データを提示するとともに，学校生活，特に休み時間や体育授業における身体活動機会の充実が必要であることを示唆した．

Title Alternative	Petrological study of Sue ware from the Sabukaze kiln site, Okayama Prefecture
FullText URL	esr_032_009_019.pdf
Author	ANAMI, Taiji\| NOZAKA, Toshio\| KIMURA, Osamu\|
Abstract	The Sabukaze kiln site, a representative ancient tunnel-kiln site in the Kibi region, worked during the Asuka period (from early 7th century to early 8th century) to produce Sue ware including jars, cups, coffins, and ornamental tiles. To determine the provenance of the materials used for the Sue ware, we carried out petrological analyses of 13 Sue sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, Raman spectroscopy, and electron-probe analysis. In spite of the difference of production time, all the Sue sherds show close similarities in modal proportion of mineral inclusions with dominant quartz and feldspar, and minor volcanic glass, in chemical compositions of feldspar and interstitial matrix, and in whole-sherd chemical composition. These similarities suggest that the paste materials of the Sabukaze Sue ware were commonly derived from weathered rhyolitic rocks and obtained from the same or neighboring mining site(s) located near the kiln site.
