In this research, we examined the hypothesis that group performance will increase as a result of accelerating the timing of goal sharing and role differentiation by height of sociality of the group such as social sensitivity and self-regulation. One hundred fifty-six undergraduates (5–7 people×26 groups) participated in consensus-building tasks. After the tasks, they completed the questionnaire about their satisfaction level, social sensitivity, self-regulation, and timing of goal sharing and role differentiation in the group. As a result of the analysis, it was confirmed that the group performance was high in the group with higher social sensitivity and self-regulation. However, the timing of goal sharing and role differentiation was not earlier in the higher social sensitivity group than in the other groups. The process in which sociality influences group performance was discussed.

Onboard REBCO (rare-earth barium copper oxide) HTS (high temperature superconducting) magnets for SC (superconducting) Maglev vehicles are being developed, that do not require refrigerants such as liquid helium. Their simplified refrigeration system results in reduced vehicle weight and makes it possible to reduce the gap between the SC magnets and guideway coils. HTS magnets are designed to operate with constant current leading by an excitation power source. By using the power source, magnetomotive force of SCMs (superconducting magnets) can be controlled.This paper describes effects of magnetomotive force control of HTS magnets on the SC Maglev vehicle system in terms of rating and efficiency of the Maglev LSM (linear synchronous motor). Using onboard REBCO HTS magnets with magnetomotive force control, the efficiency of the SC Maglev vehicle system can be increased with the same rating of the system.

The purpose of this study was to reveal the relation between the characteristics of emotional contagion and the mirror system activity. Thirty-one university students participated in this experiment. Emotional vocalizations and video of hand reaching and grasping a cup were presented to the participants. Facial electromyography (EMG) as emotional contagion index was recorded while presenting emotional vocalizations. Mu rhythm desynchronization in electroencephalogram (EEG) as mirror system activity index was recorded while presenting the video. The result shows significant correlation between the activity of facial EMG and desynchronization of mu rhythm, suggesting a person who is likely to be affected with emotional vocalizations also shows high mirror activity.

In this study, we examined the relationship between birth-month distribution, skeletal age, height, and weight in adolescent soccer players. The participants were 271 well-trained male adolescent soccer players aged between 9.1 to 15.9 years (N=101 for U12, N=132 for U15, and N=38 for U18). They were divided into four groups according to their month of birth (Q1: Apr-Jun, Q2: Jul-Sep, Q3: Oct-Dec, and Q4: Jan-Mar). Then, the number of players in each group was compared with the standard population of children in Tokyo. Our result showed significant asymmetries in the birth-month distribution for participants of all age groups (p<0.001); it was less than 10% for participants belonging to group Q4. However, no significant difference in maturation ratio (skeletal age-chronological age) was seen among the groups. Moreover, skeletal age did not differ significantly among birth-month for all groups except for Q3. These tendencies were also seen in height and weight distributions. These findings imply that players who biologically mature at an early stage may be selected systematically as soccer players at competitive levels; however, biases based on maturation and physique may cause asymmetric birth-month distribution, as seen in this study.

充分に糊化された米飯の構造とテクスチャーとの関係を明らかにするため,4種類の浸漬時間の異なる浸漬米(10℃ 0分,20分,60分,120分)を調製し,同一条件で炊飯した米飯の構造や物性を評価した。SEMでの米飯の割断面構造観察から,割断面表層付近には多孔質構造があり,最表面には緻密な層が確認できた。浸漬時間が長くなるにつれ,多孔質構造が徐々に拡大し,緻密層は120分で急激に厚くなることが分かった。また,テクスチャー試験から,浸漬時間が長くなるほど弾性率が小さくなり,破断エネルギーや粘性率も60分まで減少後,120分で増加に転じた。多孔質構造とテクスチャーとの相関を定量評価するため,画像解析により多孔質構造の孔の平均面積を求めたところ,浸漬米の水分率や弾性率と高い相関を示すことが分かった。以上の結果より,従来の糊化度評価では差がない炊飯米において,構造と破断エネルギーや弾性率といったテクスチャーとの関係を示すことに成功し,構造観察から食感を推察できる可能性を示した。

青木湖周辺には,後期更新世から完新世にかけての,おもに河成や湖成の堆積物が断片的に分布しており,下位より藪沢層,崩沢層,神城砂礫層,佐野坂崩壊堆積物,青木湖成段丘堆積物,青木湖底堆積物に分けられる.指標テフラと岩相対比によって,それらの相互関係を明らかにした.佐野坂崩壊堆積物の上位には,Dpm火山灰層がのるとされていたが,それを再堆積物と判断し,周辺の地史を次のように推定した.藪沢層は,比較的広い谷の中を南がら北へ流れる蛇行河川によって形成された.その時代は5万年前以前の寒冷な時期である.約5万年前,その河川は狭い谷の中を流れる網状河川に変化した.この堆積環境の変化は,DKP火山灰層を挾む崩沢層と神城砂礫層中部が礫を主体とすることにより示されている.約3万年前に,西方の仁科山地で大規模な地すべり崩壊が起こり,佐野坂丘陵が形成された.この崩壊堆積物は川をせき止め,丘陵の南側に深い湖(青木湖)を形成した.佐野坂丘陵の北側の凹地には支谷からの堆積物供給が多く,徐々に埋積されて,現在の神城盆地を形成するようになった.

This paper provides an overview of the Mindfulness-Based Stress Reduction (MBSR) Program developed by Kabat-Zinn. The meaning of mindfulness, Kabat-Zinn's view of mediation, and six techniques of MBSR—eating meditation, breathing, body scan, yoga, walking meditation and sitting meditation—are explained. The effectiveness of MBSR on increased stress tolerance, cognitive change, improved self-management, relaxation, increased ability for acceptance, and awareness of body sensation are introduced, and the literature reporting the applications of MBSR on patients with various conditions, including pain, anxiety, depression, eating disorder, skin disease, cancer and organ transplant, as well as its application to lifestyle modification are reviewed. Finally, potential applications of MBSR in health psychology with a particular focus in the area of health education are discussed.

The Hachinohe ash is a widespread pyroclastic-fall deposit erupted from the Towada caldera about 13, 000 years B. P. Along the dispersal axis, the thickness is 150cm 50km away from source, and the estimated volume is 14km3 It is composed of alternating beds of fine ash (65%) and pumice lapilli (35%). No erosional break is observed and the contacts between beds are gradational. The fine ash beds have two components : a dominate component of grain-supported accretionary lapilli and a subordinate component of fine ash-coated pumice; an ash matrix is lacking. The maximum grain size of accretionary lapilli does not decrease systematically away from source. The size population of constituent ash particles shows a small degree of fractionation with distance from source; the grain size class 1mm to 1/4mm increases while the class finer than 1/16mm decreases. Pumice beds are composed primarily of sub-angular to sub-rounded pumice fragments coated with fine ash and a subordinate amount of lithic fragments and accretionary lapilli. Maximum pumice size and maximum lithic size systematically decrease away from source. The beds show bimodal grain size distributions and contain more than 10 weight percent fine ash. An individual fine ash particle has too low a terminal velocity to fall out as a separate grain near the source area. It is certain that, throughout the Hachinohe ash eruption, fine ash continued to fall in the form of accretionary lapilli and/or attached to pumice fragments. The fine grained nature and wide dispersal indicate that the Hachinohe ash is representative of the phreatoplinian deposit formed by the interaction of water and silicic magma during explosive eruptions. At times when the proportion of erupted magma to lake water gaining access to the vent became sufficiently high, violet eruptions took place and deposited pumice fragments and accretionary lapilli simultaneously at the same place. Examples of phreatoplinian deposits are also reported from the Kutcharo and Hakone calderas, in addition to two other deposits from the Towada caldera. Such deposits are used as a possible indicator of source environment.

高等学校において地学教育の機会が減少の一途をたどっている.その要因の一つは,2003年度より施行された現行の学習指導要領である.「情報」・「総合的な学習の時間」・理科の3つの総合的な選択必修科目の導入による,理科の時間数減少の中で,受験に関係の少ない地学が最も削減の影響を受けたと予想される.「地学I」の全高等学校在学者数に対する履修率は3%で,理科の7つの選択必修科目の中で最も少ない.また,地学の教員が減少していることも大きな要因の一つである.高等学校生徒数の減少に伴い教員数も削減され,地学教員退職後の補充がほとんどされてない.地学が軽んじられているのは,高等学校の教育が,進路重視,入試最優先という実情にあると考えられる.今後,教育本来の目的を取り戻し,広い視点から高等学校教育を見つめ直す必要がある.

Hirobumi Daimatsu was a legendary sports coach in Japan, especially after coaching the Japanese women’s national volleyball team (“the Oriental Witches”) that won the World Championship in 1962 and the gold medal in the 1964 Tokyo Olympic Games. He was famous for his extreme training methods and had a great influence on coaching methodologies for Japanese sports as a whole. Although many studies have examined his way of thinking from various perspectives, the relationship between his war experiences and his approach to coaching has not been analyzed sufficiently. The present study aimed to examine how Daimatsu’s first-hand war experiences (“keiken”) developed into his coaching beliefs (“taiken”), focusing specifically on a theory created by Yoshida that war veterans’ understanding of their experiences had been changing over time from when they re-entered society and grew older. Yoshida made this transformation clear by referring to 5 periods since the end of the Second World War in 1945. Firstly, many demobilized soldiers including Daimatsu had to face civilians who hated the Japanese military just after defeat. They lost their morale, from 1945 to around 1950 could not talk about the military or the War. Secondly, even after former professional officers and wartime politicians had been rehabilitated, the veterans themselves still found it difficult to positively address some topics related to the War in the 1950s. Thirdly, the generation that had experienced the War who shouldered the responsibility of reconstruction from the destruction and devastation gradually gained confidence and became able to talk about their wartime experiences. Some of them discovered a positive meaning in their own experiences on the battlefield from the late 1950s to the late 1960s. Daimatsu was a typical example of the third period because he spoke clearly about the positive meaning of his war experiences. Penultimately, in the 1970s and 1980s, that generation of Japanese became able to accept the responsibility for the War, especially in Asia, and to gradually acknowledge the negative aspects of their experiences. Finally, in the 1990s, a small number of survivors chose to disclose tragic stories that had not come to light previously. Thus, Daimatsu was only one of a generation that had experienced the War and who became recognized as a spokesman for many of that generation who held common feelings.

Background:Various issues, such as gender diversity and overwork, need to be considered in cardiovascular workplaces. Here, we report the results of 2 questionnaire surveys conducted among members of the Chugoku branch of the Japanese Circulation Society.Methods and Results:The first questionnaire was posted to all 194 female members in 2018. Of the 73 respondents, 61.6% reported feeling that it would be difficult to continue in cardiovascular care. The second questionnaire was completed by participants of the Chugoku Regional Meeting in 2019. Of the 133 respondents, 42.4% reported difficulties continuing in cardiovascular care. Respondents reporting difficulties had a significantly lower mean age, a higher frequency of day and night shifts, and a higher rate of working >80 h/week than respondents who did not report such difficulties. In logistic regression analysis, working >80 h/week was the only independent factor associated with difficulties continuing in cardiovascular care (odds ratio 4.16; 95% confidence interval 1.46–11.9; P=0.008). Although 47.4% of respondents worked >960 h overtime per year (considered a risk factor for death from overwork), 59.6% of these respondents reported being satisfied with their current situation.Conclusions:In the Chugoku region, the work-life balance of medical personnel engaged in cardiovascular care has not been sufficiently secured. In order to promote diverse human resources, we need to recognize the current situation and continue to take countermeasures.

夫婦間の家事分担は,収入や時間的制約の差を考慮に入れても,実際の家事の多くを妻が担っているという不公平な状態になっている。それにもかかわらず妻側の不公平感は高くなく,こういった状態は経済的・時間的要因では説明ができない。これに対してジェンダー理論では妻の伝統的性別役割分業意識が強い場合は不公平感が弱いという説明を行ってきた。本論文ではこれに加え,特定の家事分担状態が不公平であるかどうかの判断基準には,社会的環境の影響も強く働いていると予測する。つまり自分が属している社会の分担水準が公平の判断基準となり,それが自分の家事分担の不公平感に影響していることが考えられる。家事分担と不公平感に関する国際比較データから,妻の家事分担比率が高い国,性別役割分業意識が強い国では,実際に妻の家事負担が大きく,また,妻が長時間働いていたり,高学歴であっても,不公平感をもちにくいということが明らかになった。
