Objectives: In this study, we aimed to categorize the actions of occupational physicians in health committees leading to solutions of occupational health problems.Methods: We conducted two focus group discussions among experienced occupational physicians. The discussions addressed the following question: what had they and others said and done that had led to the development of solutions to occupational health problems. We used a qualitative content analysis approach developed by Berelson, and created a draft of the categories of actions. Subsequently, an online questionnaire survey was then used to evaluate the external validity of the draft. The questionnaire asked physicians whether they had experience of each item in the draft. They were also asked whether they had experienced any other items not included in the draft. If so, they were asked to provide a description of their experience. These descriptions were discussed by three researchers. Any suggested new items considered to fall under any of the original items in the draft were excluded, and any new items proposed by two or more participants were added as additional items. Finally, we corrected words and phrases and reviewed the items to ensure that they clearly conveyed the required meaning, and described actions leading to solutions to occupational health problems.Results: The content analysis revealed six basic actions, and 32 items were categorized in the draft. The six basic actions were “participate”, “gather information”, “make a place that allows communication with key people and health committee members”, “make arrangements”, “speak at a health committee”, and “pay attention”. In total, 67 physicians responded to the questionnaire survey. At least 40% of participants answered that they had experience of the draft items. All items in the draft had also been experienced by groups of occupational physicians other than those involved in the focus groups. Three additional items proposed by two or more participants were added. “Pay attention” was deleted following the final review.Conclusions: We categorized the actions of occupational physicians in health committees into five basic actions, and 32 items. Being aware of types of actions used in groups may encourage occupational physicians to be more involved in workplace health committees and contribute to the promotion of occupational health activities in the workplace.

近代中国における「日曜日」の受容に関しては、これまで文学や歴史学、社会学などの分野において研究が進められてきた。しかしながら、それらの先行研究の大多数は、民国期に重点が置かれたものであり、清末期における「日曜日」の受容についての考察は十分とは言えない。本稿は、清末における一週七日制の名称を検討した上で、清末の新聞『申報』の記事を中心に、休息、娯楽、および犯罪事件といった三つの観点から清末における「日曜日」の受容を考察するものである。

The primary aim of this paper is to re‒evaluate female labourers' participation in the Preston strike of 1853. This paper also explores how and why those female labourers came to demand the withdrawal of married women from the labour market, despite the fact that they had been obvious participants in labour movements. Much of the research on the Preston strike of 1853 has not give sufficient attention to women’s roles in the strike, so this study seeks to compensate for that neglect through an examination of local newspapers such as the Preston Chronicle and contemporary pamphlets. The investigation shows that women were important supporters of the strike through their attendance at operatives’ meetings, subscription to strike funds, and criticism of blacklegs.This paper discusses the fact that the demand by females that married women leave the factories was the result of the influence of the Chartist and factory reform movements of the 1830s. Female labourers actively participated in the 1853 strike having already forged their identity as wage labourers, but they were affected by the shared perspective of the two movements regarding female wage labour, and especially the view that married women’s wage labor constituted a social problem and that women’s duty as wives and mothers should be emphaslzed. The evidence suggests that by expressing sympathy with the resolution calling on all married women to withdraw from the labour market, female labourers expected the following results : first, an increase in wages(especially for males) due to the restricted supply of labour ; second, the alleviation of the double burden on married women who were responsible for both wage labour and housework ; and finally, maintenance of the economic independence of single women labourers.The agreement with the prohibition of married women's wage labour shows that married and unmarried women had different identities, and that they differed not only in social status but also in their own awareness of themselves. This paper concludes that this divergence in identities was a product of the gap between the working‒class ideal of family‒wage/male breadwinner ideology and the reality of English society, which relied on a female labour force. Nevertheless, though confronted with opposition to women’s wage labour, female labourers maintained their position as wage‒earners and did not cease to support labour movements in the nineteenth century. And their experiences as important actors in labour agitations can be understood as a pard of the prehistory of the female labour movements that flourished after the 1870s.

Humans develop their concept of an object by classifying it into a category, and acquire language by interacting with others at the same time. Thus, the meaning of a word can be learnt by connecting the recognized word and concept. We consider such an ability to be important in allowing robots to flexibly develop their knowledge of language and concepts. Accordingly, we propose a method that enables robots to acquire such knowledge. The object concept is formed by classifying multimodal information acquired from objects, and the language model is acquired from human speech describing object features. We propose a stochastic model of language and concepts, and knowledge is learnt by estimating the model parameters. The important point is that language and concepts are interdependent. There is a high probability that the same words will be uttered to objects in the same category. Similarly, objects to which the same words are uttered are highly likely to have the same features. Using this relation, the accuracy of both speech recognition and object classification can be improved by the proposed method. However, it is difficult to directly estimate the parameters of the proposed model, because there are many parameters that are required. Therefore, we approximate the proposed model, and estimate its parameters using a nested Pitman--Yor language model and multimodal latent Dirichlet allocation to acquire the language and concept, respectively. The experimental results show that the accuracy of speech recognition and object classification is improved by the proposed method.

From the early stages of the COVID-19 outbreak, there have been many reports on cluster infections in clubs and bars. Meanwhile, there is no report on the indoor air environment in those places and it will limit measures for infection control. This study aims to understand the indoor air and ventilation environment and to propose practical and appropriate improvement measures for related industries. In addition to measuring CO2 concentration in clubs and bars in Tokyo, we have surveyed the voluntary measures taken against COVID-19, outlines of building and ventilation/air conditioning equipment, ventilation regime, and so on.

キュウリに含まれるギ酸の分布および味覚特性を明らかにするため, まず, HPLC法による分析法とキュウリ試料調製法について検討を行った。設定したHPLC分析法のギ酸定量限界は0.5 mg/Lであり, 再現性も良好であった。キュウリは, 果皮, 維管束, 果肉および種子, それぞれの部位に分け, HPLC分析試料を調製した。HPLC分析の結果, ギ酸は果肉と種子では検出されず, 果皮と維管束に局在することが示された。ギ酸標準水溶液の味覚特性を調べた結果, 低濃度 (<10 mg/L) では渋味を感じ, 濃度が高くなるに伴って渋味とともに苦味と酸味も強くなった。キュウリの渋味とギ酸濃度との関係については, 特に果皮を食したときに感じられる渋味は, ギ酸によるものと推察された。さらに, ギ酸を各種濃度に調整したキュウリの官能結果からも, ギ酸がキュウリの渋味の主な要因であることが示唆された。

本論では,海底地すべりの一般的な特徴,短期および長期の発生メカニズム,海底地すべりによる海洋ハザードについて概説する.海底地すべりは,その形状から,一般的に滑落ドメイン,移動ドメイン,末端ドメインの3つの領域に区画される.滑落ドメインでは開口亀裂,移動ドメインでは剪断変形に起因する非対称変形構造が見られる.末端ドメインでは,圧力隆起部によって特徴づけられる.滑り面は粘土層であると推測されるが,南海トラフで報告されているように非条件下では,砂層も滑り面となる可能性がある.短期的な発生メカニズムは,斜面における荷重の急激な増加や間隙水圧の急激な上昇など,地震に最も関連している.長期的な発生メカニズムは,気候変動によるメタンハイドレートの分解とそれに伴う間隙水圧の増加,長期的な間隙水圧の増加,海山の沈み込み/衝突による地盤の変形,火山活動による斜面勾配の急斜化などがある.

自然言語の意味論はモンタギュー以来、モデル理論的意味論が主流であったが、ランタらによる証明論的意味論の流れが存在する。特に近年、著者ら自身の研究を含む理論的進展により、証明論的意味論の経験的、計算的優位性が明らかにされつつある。本発表では、証明論的意味論の中心的枠組みの一つである依存型意味論(DTS)を紹介するとともに、その言語学的意義、哲学的位置付け、自然言語処理への応用などについて解説する。

This study targeted six exhibition zones with different characteristics at the Yokohama Zoo “Zoorasia ,” which grasped visitor satisfaction at each exhibition zone, clarified the relationship between visitor satisfaction and the purpose and attributes of visitors, identified the management and operation issues at each exhibition zone from a visitor satisfa ction perspective, and examined the factors that led to its occurrence. Ultimately, the aim of this study was to discuss a response policy in relati on to the management and operation policy of Zoorasia. The main results of this study are as follows:(1) Visitor attributes are classified into three types. (2) The degree of visitor satisfaction varies by exhibition zone and visitor type. (3) The factors affecting overall visitor satisfaction vary by exhibition zone and visitor type. (4) The management and operation issues (important improving items) vary by exhibition zone. With the above results, the response policy was discussed by relating issues in the management and operation of each exhibition zone with the current management and operation policy.
