Dietary sodium sources according to four 3-d weighed food records and their association with multiple 24-h urinary excretions among middle-aged and elderly Japanese participants in rural areas
No full textReducing Na intake is an urgent global challenge, especially in East Asia and high-income Asia-Pacific regions. However, the sources of Na and their effects on urinary Na excretion have not been fully studied. We sought to clarify these sources and their association with urinary Na excretion. We examined four 3-d weighed food records and five 24-h urinary collections from each of 253 participants in Japan, aged 35–80 years, between 2012 and 2013. We compared the levels of Na according to four categories: foods contributing to discretionary or non-discretionary Na intake, the situation in which dishes were cooked and consumed, food groups and types of cuisine. We also conducted regression analysis in which 24-h urinary Na excretion was a dependent variable and the amounts of food intake in the four categories were independent variables. Levels of Na were the highest in discretionary intake (60·6 %) and in home-prepared dishes (84·0 %). Of the food groups, miso soup showed the highest percentage contribution to Na intake (13·3 %) after seasonings such as soya sauce. In the regression analysis, the standardised coefficient for foods of non-discretionary Na sources was larger than that for discretionary sources, whereas that for home-prepared dishes was consistent with the levels of Na in those foods. Pickled products, followed by fresh fish and shellfish, miso soup and rice, were associated with high urinary Na excretion. Thus, discretionary foods (such as miso soup) contribute the most to Na consumption, although non-discretionary intake (such as pickled vegetables) may influence urinary Na excretion.journal articl
弓道の握り革の使いやすさが手の内の力に及ぼす影響
No full textNigirikawa is a leather tape attached to Japanese bow in Kyudo. It assists the “Teuchi” (the method of gripping bow), which is to twist the bow counterclockwise to make the arrow fly straight. Kyudo players select the materials of the Nigirikawa for ease of use from subjective impression. The objective of this study is to examine the effectiveness of grip strength in drawing the bow as an objective evaluation index. We attached four pressure sensors to the grip of the bow to measure the pressure during shooting and compared the four types of Nigirikawa (deer, shark, cow, and sheep). The results showed that the differences of gripping force depending on the ease of use of the Nigirikawa in two movements of “Daisan” and “Kai”. Therefore, we concluded that gripping force is effective as an objective evaluation index of Nigirikawa.journal articl

再帰性反射に基づく外装材の表面形状の最適設計手法に関する研究
No full textヒートアイランド対策として用いるのに適した，近赤外光線再帰反射に基づく外装材の表面形状の最適設計手法を提案した。最適解の探索手法として遺伝的アルゴリズムを用い，評価対象である形状ごとの反射分布特性の推定にはレイトレーシング法を用いる。この手法では，設計目標を目的関数として設定することにより，各表面形状のパフォーマンスを定量的に評価することが可能である。また，設計目標への達成度を適切に評価することができる目的関数の選定を行った。この研究で提案された手法によって最適化された表面形状は，設計目標を達成していた。外装材の最適設計手法のプロトタイプを提案することができた。journal articl
Motor imagery and action observation of whole-body movements for experienced motor repertoire: an fNIRS study
No full textThe present study used functional near-infrared spectroscopy (fNIRS), and investigated the characteristics of hemodynamic responses of oxy-Hb and deoxy-Hb during motor imagery and action observation for whole-body movements. Sixteen female participants performed tasks under two conditions: motor imagery and action observation. Each condition included three tasks of whole-body movement of gymnastics: (1) forward roll, (2) backward roll, and (3) cartwheel. Under both motor imagery and action observation conditions, the mean amplitude of oxy-Hb in the left posterior parietal cortex (PPC) was significantly more positive for the forward roll than cartwheel. The mean amplitude of deoxy-Hb was significantly more negative for the cartwheel than forward roll in the middle PPC. These findings suggest that PPC plays an important role in representations of movement during motor imagery and action observation. In addition, correlations between the vividness of motor imagery and mean amplitudes of oxy-Hb were identified in the premotor and primary motor areas. These results suggest that psychological assessments for vividness are linked to neural motor processes, and may provide a valid and economic tool to evaluate a person’s ability to perform motor imagery.This study was supported by a Japan Society for the Promotion of Science KAKENHI Grant-in-Aid for Scientific Research C (19K11576) (to H.

模様の回転と帯の長さに基づく花紋スモッキングの動的可視化
No full text布のねじり折りと縫い留めで被服の装飾となる模様を造形する花紋スモッキングに対し，折りの程度に応じて模様と帯が変化することで折り途中の様子が可視化されるように，本稿では模様の回転と帯の長さに基づいて花紋スモッキングを作図するアプローチを提案する．折りの様子を可視化することにより，時間をかけて作図したにも関わらず模様が重なってしまい装飾として制作できないことを避けたり，折り途中の様子を確認することで柔らかな布の折りたたみでの造形がしやすくなると期待される．提案法では帯をねじるように折る代わりに模様を一斉に回転させるとともに，折り途中の様子を表す帯が回転に応じて定まるように作図する．提案法による作図の幾何的な性質を示すとともに，この性質に基づいて作図するプロセスや作図例を報告する．提案法を GeoGebra を用いて実装し，花紋スモッキングを施した服飾雑貨の例としてバッグを制作して検証した．布の折りたたみで容量を可変にできるようにマジックテープを用いて制作したバッグは折り後の形状を維持しやすくなるとともに，折り途中の様子を確認することで容量の変更をしやすくなった．journal articl
Synesthesia has specific cognitive processing during Go/No-go paradigms
No full textGrapheme-color synesthesia is a consistent and automatic perception of non-physical color when presented with a grapheme. Many previous studies focused on the synesthetic visual system, but other cognitive functions in grapheme-color synesthetes have remained unclear. Therefore, the objective of the present study was to investigate the characteristics of cognitive processing for motor execution and inhibition during Go/No-go paradigms in grapheme-color synesthesia using eventrelated potentials (ERPs). Six grapheme-color synesthetes and 24 non-synesthetes performed visual, auditory, and somatosensory Go/No-go paradigms. Omission errors were higher in grapheme-color synesthetes than non-synesthetes. Group-trial interactions (i.e., synesthetes–non-synesthetes×Go–No-go) were observed for the latency of the visual N2 component and amplitude of the somatosensory N2 component. Latencies of auditory and somatosensory P3 components were shorter in graphemecolor synesthetes than non-synesthetes. These findings suggest that grapheme-color synesthetes have specifc cognitive processing in motor execution and inhibition as well as synesthetic color perception. Our data advance understanding of cognitive processing in grapheme-color synesthesia.journal articl

思春期世代の自己肯定感・孤独感と他者とのつながり:内閣府「子供・若者総合調査」の実施に向けた調査研究(令和3年度)より
Get PDF本研究は,内閣府により,子供・若者の意識及び行動に関する総合的な調査研究(「子供・若者総合調査」)を実施するための予備調査として行われたものの一部である。対象は,層化二段無作為抽出法による10 ～ 15歳の男女,3,600人。2022年2月に郵送とオンライン回答の併用で実施された。その結果,家族や学校・地域社会にしっかりと絆を築けている子どもたちは,自己肯定感や孤独感も比較的高いが,ネット空間に頼りがちな子どもたちは,現実の他者との関係が結びにくく,孤独感の強さや自己肯定感の低さという点で特徴が見られた。さらに,年齢とともに,家族(家庭)や友人(学校)より,自分の部屋やネット上という“個になれる空欄"を居場所とする割合が増えるが,家族や友人,地域という身近な人との関係からの離脱は,自己肯定感の低下や強い孤独感にもつながり得ることが示唆された。奈良女子大学心理臨床研究 第10号 第1部 研究論文departmental bulletin pape
