We herein report on a 62-year-old man who presented with symptoms of intermittent fever that persisted after returning from a trip to France. During his trip, he had eaten natural cheese. Although no bacteria could be isolated from blood culture, the serum agglutination test showed a positive antibody titer of 1 : 160 for Brucella canis. The patient responded well to combination antibiotic therapy consisting of gentamicin, rifampicin, and doxycycline, and his symptoms improved. He became antibody-negative after antibiotic therapy. Although the present case may have been a case of B. canis infection, considering the epidemiology of brucellosis in France, serological cross-reactivity with Brucella melitensis infection is also a possibility. Concerns regarding the reemergence of brucellosis have recently been reported in France, and most cases are caused by B. melitensis. Clinicians should be aware of the fact that blood cultures must be incubated for ≥21 days for isolation of Brucella and that in Japan, antibody measurement of B. melitensis cannot be performed on a commercial basis.

Both germicidal Lamps made in Japan and the United States were effective in killing bacteria in the air and the tin-foil can prepared for the dried milk packaging, but less effective in fluid milk and dried milk except the mold in butter.In case of granular sugar, the thin layer of sugar and long time of irradiation neccesary to destroy bacteria and mold appeared to make this procedure difficult commercialy.American niade apparatus was stronger than Japanese one in its killing power.

We investigated the distortion that occurs during the storage of representations in visual short-term memory by using smooth closed figures with varying stimulus complexity and similarity. In similarity judgments, the results suggested that the psychological similarity between two figures was based on averaging physical similarities of matched features. In a detection experiment, the results showed that the processing of detection was limited in its capacity for the precision of shape, and that it was more difficult to detect the precise shape in the case of complex figures. In a recognition experiment, the results showed that forgetting occured during a one-second retention interval. These two results showed that internal noise distorts both detection and retention processes. These findings suggested that representations of the complex figures with many features were distorted to a larger degree because each feature was individually masked with internal noise. It is concluded that the psychological similarity between an input pattern and a distorted pattern stored in short-term memory is invariant with stimulus complexity.

NPO法人Science and Artでは幼児期からの理科離れ対策として、2016年以来幼稚園における自然科学教育を展開し、年少児から小学校2年生まで毎週9クラス(幼児60名・小学生8名)の自然科学教室を展開している。本研究発表では以下の3つのプログラムとその教育効果について紹介する。1・化石発掘体験2・鉱物万華鏡3・恐竜カルタ化石発掘体験では実物のアンモナイトを石膏と砂を混ぜた土台に埋め込み、子供達に割り箸とゴムハンマーで発掘の感覚を味わってもらう。この際、子供のレベルに応じて土台の硬さを調節することにより醍醐味が変わってくる。模擬的に発掘された化石にはラベルをつけて自分の標本として自分で管理させる。鉱物万華鏡では水晶(石英・紫・ピンク)やカンラン石のなどの色石のさざれ石を利用して万華鏡を作る。石の観察を行いながら、その起源や産地の話題へと話を発展させる。恐竜カルタでは通常のカルタ遊びを行いながら、カルタに出てきた恐竜や海棲爬虫類の標本(レプリカ・実物化石)を見せたり触ったりさせる。図鑑も多用してカルタに書いてある文字以上の情報を図鑑から得る方法を教える。本プログラムのフィードバックを紹介することで、いずれも幼児期から楽しみながら地学に触れることができるだけでなく、その後の興味を伸ばす要素も含んでおり、幼児期からの地学教育において画期的なプログラムであると提案したい。
