Background: The incidence of venous thromboembolism (VTE; pulmonary embolism [PE] and/or deep vein thrombosis [DVT]) in Japan is increasing, but relatively small numbers of patients from Japan have been included in studies investigating rivaroxaban (a direct factor Xa inhibitor) for the treatment of VTE and preventing its recurrence.Methods and Results: An open-label, prospective, observational study (XASSENT [NCT02558465]) investigated the safety profile and effectiveness of rivaroxaban for ≤2 years in the treatment of VTE and prevention of its recurrence in Japanese clinical practice. Primary outcomes were major bleeding and symptomatic recurrent VTE. Statistical analyses were exploratory and descriptive. Overall, 2,540 patients were enrolled (safety analysis population [SAP], n=2,387; effectiveness analysis population [EAP], n=2,386). In the SAP, >80% of patients received the approved rivaroxaban dose, the mean (standard deviation) age was 66.6 (15.0) years, ≈74% were >50 kg, and 43% had a creatinine clearance ≥80 mL/min. PE+DVT, PE only, and DVT only were reported in 42%, 8%, and 50% of patients, respectively, and active cancer in 17% of patients. Major bleeding was reported in 69 patients (2.89%; 3.60%/patient-year; SAP) and symptomatic PE/DVT recurrence in 26 patients (1.09%; 1.36%/patient-year; EAP) during the treatment period.Conclusions: XASSENT provided information on the expected proportions of bleeding and VTE recurrence during rivaroxaban treatment in Japanese clinical practice; no new concerns of safety or effectiveness were found.

平成20年告示の中学校学習指導要領において,「進化」と「遺伝(の規則性)」が復活し,平成29年改訂では「進化」が第2学年から第3学年に移行し,「遺伝」の学習後に扱われるようになった.「進化」と「遺伝」は「細胞説」と並び生物学上の重要な概念である.しかしながら,過去の学習指導要領においては,「進化」と「遺伝」は削減と復活を繰り返してきた学習内容である。本研究では,このように重要な科学的概念がなぜ学習内容から消え去る時期があるのかを究明することを目的とした.この点に鑑み,戦後8回にわたる学習指導要領・その解説・教科書などの記述を調査し,さらに当時風靡した言説・進化論争・優生学など社会的歴史的背景を論じた文献を調査した。その結果,優生保護法・遺伝決定論・反ダーウィニズムの台頭などの共通項が浮かび上がってきた.一時の要請に左右されない科学的進化理論・遺伝理論を中心置いた生命教育が望まれる.

This study aimed to develop the Japanese version of the Lesbian, Gay, and Bisexual Identity Scale (LGBIS). The original scale was designed to assess the acceptance of one’s identity as an LGB person. We examined the reliability and validity of the translated Japanese version using data from 703 Japanese LGB people. The results of exploratory and confirmatory factor analyses showed that the Japanese version of the LGBIS has a four-factor structure, in contrast to the eight-factor structure of the original version: negative image and affect toward LGB identity, identity centrality, identity affirmation, and identity uncertainty. Furthermore, internal consistency and test-retest correlations indicated that the scale has good reliability. The four subscales correlated with various identity-related measures. The correlations between indicators of mental health and both negative affect and affirmation about LGB identity were mostly consistent with the current theory of minority stress, which provide evidence of good validity for the Japanese version of the LGBIS. Thus, the Japanese version of the LGBIS is suitable for the assessment of identity acceptance among the Japanese LGB population.

Workplace changes, such as remote work during the COVID-19 pandemic, have caused serious psychological distress for workers. The aim of this study was to examine job stressors and coping strategies among Japanese workers during the pandemic. The study was a qualitative methods approach using a web-based survey for Japanese workers in May 2020. We asked about job stressors and coping strategies with free text comments. We performed context analysis and categorized job stressors and coping strategies. Of the participants, 59.2 % suffered psychological stress from workplace changes during the pandemic. We identified 11 categories of job stressors including “work-life balance,” “lack of communication,” “overwork,” and “diminishing work role.” We also identified 16 categories of coping strategies including “distraction,” “dealing with work tasks,” “looking for ways to communicate,” “environmental coordination of work-at-home,” “online chatting,” and “psychological disengagement.” This study shows that Japanese workers tried many ways to manage their job stressors under the burden of the state of emergency. In the future, we should examine the association between coping strategies and psychological distress during the COVID-19 pandemic.

In order to achieve unmanned construction with a pneumatic caisson method, the present study develops an autonomous operation system using caisson shovels. The shovel mounted on the ceiling slab of the working chamber moves on a rail track and excavates underground based on the trajectory of a skilled human operator. The excavated soil is removed to the aboveground space through the material shaft using earth buckets. Since the rail track constrains the moving range and the shovel cannot always approach the earth bucket, groups of several shovels are organized to perform cooperative work based on a bucket relay system. In the present paper, we proposed a job scheduling algorithm based on terrain recognition, soil mountain selection, excavation trajectory control, and collision avoidance for an autonomous operation. Here, we used a 1/10-scale caisson platform reproducing a practical construction site and performed three cases of cooperative experiments by (a) a group of two shovels, (b) two groups of two shovels, and (c) three groups of two shovels. The results showed that, in case (a), the loading ratio always remained over 100% and the average was 130%. The cooperation of two shovels was achieved. In case (b), sharing an initial soil mountain between two groups, although the loading ratio decreased by 18%, cooperative work between groups as well as that between shovels was achieved without collisions. In case (c), sharing two initial soil mountains among three groups, the loading ratios were 126%, 107%, and 96% for the three groups. The proposed excavation planning showed the feasibility of massive construction using numerous autonomous shovels.

ラハール堆積物は,平均粒径-標準偏差の関係,粒径の分布型の違いから,粘着性の泥流堆積物,非粘着性の土石流堆積物と高密度洪水流堆積物の3タイプに識別することが出来る.2013年10月16日未明に伊豆大島で発生したラハールは,伊豆大島火山西斜面を被覆していた降下細粒火山灰層が表層崩壊を起こしたもので,堆積物の粒度組成の特徴は,この流れが高密度洪水流であったことを示している.すなわち,土石流のような巨・大礫が集合したものではなかったことが今回の土砂災害の大きな特徴となっている.今回のラハールは斜面崩壊発生時から流体として流れ出したため,斜面を面状に高速で流れ下ったものとみられる.この種の土砂災害は,他火山でも発生事例があり,防災上考慮しておく必要がある.

To encourage older adults to participate in exercise, it is important for self-governing bodies to divide them into subgroups according to exercise habit and to determine facts such as what they think about exercise and what type of programs would help them most. In Japan, however, few such schemes have been reported. This study aimed to clarify the process of ascertaining the characteristics of older adults and to establish a challenging means of encouraging continued exercise. The eligible study population was all residents aged 65-69 years living in Isobe town, Mie Prefecture, Japan (n = 675) , 460 (68.1%) responded to our questionnaire during a two-month period (November-December) in 2003. The respondents were divided into subgroups according to exercise frequency: those exercising twice a week or more (21.1%, Group A) , once a week (6.3%, Group B) , once or twice a month (7.6%, Group C) , and no exercise (65.0%, Group D) . Group A exercised because they believed they became healthier or achieved an improved fitness level. Group B undertook exercise as they regarded rapport as important, i.e. making friends at group exercise classes. To the question “Why don't you exercise?” Group C noted the lack of an exercise companion, and Group D noted low motivation. From the responses to “What type of approaches do you look for so that you might start exercise?” Group C suggested approaches such as an invitation to join an exercise class, or an introduction to an exercise instructor, and Group D suggested an exercise program that they could perform at home. Based on these results, a challenge for each group was established: to maintain the exercise frequency (Group A) , to increase awareness of the effects of exercise (Group B) , to participate more in group exercise sessions (Group C) , and to experience an easy-to-use home exercise program (Group D) . Future research is required to ascertain the effects of such challenges on exercise habit in older adults.

In the present study, we reconsider the pioneers of the intraoral radiography. In intraoral radiography, the bisecting-angle technique was first published by Weston Andrew Valleau Price in 1904, and Antoni Cieszyński devised the same method in 1907. The paralleling technique was first used by Charles Edmund Kells in 1896. Then, in 1911, Franklin W. McCormack introduced the long-distance technique into the paralleling technique and published his findings in 1920. It was integrated and improved, and was popularized by Gordon M. Fitzgerald as a long cone paralleling technique between 1947 and 1950. The author proposes that the above should be the established theory in Japan.

高度経済成長以降の日本では、都市部への人口流出が進んだ。1970年代の都市部には幼少期を農村地域で過ごし、大学進学や就職を機に上京する若者が急増した。この時期における農村へのUターンという行為は、「都市での挫折」を想起させる場合もあった(山田1992)。しかし、1980年代には農村回帰を志向する都市住民があらわれ、農村に都市住民が移り住む現象を「田舎暮らし」と称し、次第に様々な雑誌やテレビ番組を通して、社会現象として取り上げられるようになった。「田舎暮らし」という現象はいつから生じ、都市住民のイメージする「農村での暮らし」はどのように変化したのか。本発表は、都市住民の農村移住、とくに「田舎暮らし」というキーワードに着目し、その実態と変化を検討することを目的とする。本発表では、新聞記事、雑誌『田舎暮らしの本』などメディアによるイメージの形成や、民間企業による商品造成、自治体による移住促進事業など、「田舎暮らし」をめぐる様々な動向を踏まえ、以下の4つの時期に分けて検討した。。1983年に「田舎暮らし」という言葉が用いられるようになった当初、その暮らしぶりは、都市的要素を極限まで排した原始的な農村生活と、有機農業に従事した生活設計が追求されていた。有機農業や自給自足、農地や家屋、生活財の手作りにこだわるライフスタイルは、現在の「田舎暮らし」でも志向されており、都市とは対極の存在として「田舎」を認知する農村観は、30年経過した現在も変化していない。バブル経済期や2007年問題など、社会の大きな変動を背景として、「リゾート」や「グリーンツーリズム」、「農村回帰」、「団塊世代」、「エコ」、「ロハス」など、その年々の流行を取り入れつつ、「田舎暮らし」のイメージは著しく変化してきた。そこには、「田舎暮らし」をあっ旋する民間企業や情報発信するメディア媒体、支援事業を実施する行政、受け入れる地域社会、移住者自身など、様々な主体の思惑や価値観が存在し、これらがせめぎ合うことで、それぞれの時代に適合した「田舎暮らし」を商品化してきたことが明らかとなった。

We aimed to easily make an automatic monitoring insect trap by combining a commercially available IoT monitoring camera with a sticky pheromone trap that was assembled from parts of commercially available sticky traps in order to grasp the number of daily trap catches of insect pests on the same day. This trap is hereafter referred to as the IoT camera-equipped sticky pheromone trap. In the present study, we applied the IoT camera-equipped sticky pheromone trap to Spodoptera exigua (Hübner) and examined whether it was possible to record the daily catches of S. exigua males by the trap. According to the predetermined settings, the IoT camera automatically took a picture (3 million pixels) of the sticky board capturing S. exigua males at 9:00 AM and then immediately sent the image with lowered resolution (0.3 million pixels) to a designated e-mail address via mobile networks (LTE) of a cellular carrier (NTT docomo). Trapped S. exigua males appearing in the sent images of the sticky board could be distinguished from other insects and counted on the monitor screen of a personal computer. The number of trapped males was also counted by directly checking the sticky board in the field every 2–4 days. On each day that trapped S. exigua males were directly counted in the field, the number of S. exigua males coincided with that counted through viewing the e-mailed image. These results suggest that the daily catches of S. exigua males can be grasped using the IoT camera-equipped sticky pheromone trap. Thus, this trap might be useful for monitoring the daily occurrence of insect pests, but this needs to be verified by applying it to various insect pest species.

本論文では,日本での自己調整学習とその関連領域における研究の動向を明らかにし,今後の研究の方向性を明らかにすることを目的として研究レビューを行った。特に,近年の学校教育において自己調整学習への関心が高まっていることに鑑み,小学生から高校生を対象とした研究に焦点をあてた。2011年以降に日本の主要雑誌に掲載された論文を検索し,52論文を抽出した。レビューの結果として,(a)小学生から高校生までを対象とした研究があり,英語や算数・数学における研究が多いこと,(b)自己調整学習の主要な要素であるメタ認知,動機づけ,学習方略のいずれも研究の対象となっているものの,3つの要素すべてを扱っている研究は少ないこと,(c)自己調整学習の要素を用いて学業成績を予測するような調査研究から,介入によって自己調整学習を促そうとする実践的な研究まで幅広くみられること,が明らかになった。日本における今後の研究の方向性として,自己調整学習の理論と教育実践とのつながりをもつ研究が増えていくことが予想される。そのなかで,「理論をもとに実践を創る研究」と「理論をもとに実践を切り取る研究」の2つの方向性を示唆した。
