最近,日本人の精巣重量およびサイズ等に関して検討を行なった報告は,ほとんど見られない.今回,われわれは,747例の変死体剖検症例を対象として,そのうちの651例について精巣重量とサイズの検索を行なった.重量,厚さはp<0.01で右の方が大きく,20〜49歳の平均精巣重量は左14.53±4.07g,右15.35±4.26g,平均サイズは左長径4.51±0.64cm,短径3.04±0.43cm,厚さ1.43±0.3cmで,右長径4.53±0.61cm,短径3.05±0.4cm,厚さ1.55±0.33cmであった.また両側精巣とも重量,長径,短径で30歳代が最大との結果が得られた.

本稿は、戦国期における鷹狩の様相について、足利将軍家・細川京兆家・公家を中心とした鷹狩の事例と、鷹狩の獲物である「鷹の鳥」進上例をもとに検討した。15世紀末~16世紀初頭の細川政元の鷹狩・鹿狩は軍事的色彩が濃かったのに対して、16世紀前半の11代将軍義澄・12代将軍義晴・13代義輝は、近臣と親交を深める鷹狩を行い、将軍の側近であった公家も漑狩をするようになった。また、漑の鳥が禁裏へ進上されることが定着し、平安時代以来衰退した天皇を中心とした鷹狩の構造が再構築されたことを明らかにした。

1)野菜を次亜鉛素酸ソーダで殺菌したとき生成するクロロホルムを除去する方法について検討した。処理野菜を十分に水洗するかまたは冷凍庫にて48時間保存することにより、生成したクロロホルムの大部分を除去することが出来た。2)次亜鉛素酸ソーダ処理した野菜のビタミン含量について検討した。千切りに刻んだキャベツではビタミンB_1、B_2、Cの50%前後が処理により破壊したが、包丁を入れていない春菊ではビタミン類の、破壊は全く認められなかった。3)野菜の次亜鉛素酸ソーダによる殺菌はカット野菜ではなく、包丁などで切っていない野菜について行い、その後十分に水洗することにより、食品衛生上、栄養面の両方において不都合なく行えることが明らかとなった。

In full-grown larvae (50mm or a little more in body length) of Malacosoma neustria testacea Motschulsky, extirpation of either the prothoracic or the mesothoracic ganglion results in a marked distension of the body within about 24 hours. The body becomes fully stretched, attaining about 70mm in length. The larvae become almost unable to move, except that they show a continuous biting and swallowing movement of mouth-parts. The alimentary canal is filled with air thus swallowed. When punctured by needle, the air escapes from the alimentary canal and the body immediately becomes reduced in size (see Figs. 1 and 2). After removal of the subesophageal ganglion or of the brain, the mouth-parts become immobile. In these larvae, extirpation of the prothoracic ganglion no longer causes the distension of the body. If the mouth and anus are closed with paraffin immediately after removal of the prothoracic ganglion, no distension of body can be observed. It is obvious, therefore, that the body distension following removal of the prothoracic ganglion is largely attributable to an abnormal intake of excess amount of air into the alimentary canal. Extirpation of the prothoracic ganglion appears to bring about a failure of a proprioceptic inhibitory mechanism. In younger larvae, mature larvae or prepupae no distension of body takes place after removal of the prothoracic ganglion. In the silkworm (Bombyx mori, L., J-122×C-115) deprived of the prothoracic ganglion, the distension is very slight.

Japan occupied the island of Hainandao just before the Asia Pacific War.The Japanese army murdered many Hainandao inhabitants during this occupation. Nevertheless the facts of these massacres have been suppressed and neglected by japanese government and people after the war. We have been researching the facts of the massacres by the Japanese army through interviews with the survivors in Hainandao. As a result we found these massacres did not happen accidentally, but were purposely carried out in accompaniment with the military operations of the Japanese army. These massacres took place continually from February 1939 to August 1945. I analyzed the Military Diary of the Japanese Navy in Hainandao. Recorded in this diary is not only military operations in the narrow sense, but also various government policies. For example, the mining of natural resources, management of land, control of prices, the education for the island inhabitants, and securing human resources. The aim of the Japanese army was to continue its war effort by pillaging resources, food, and using forced labor, among other things. It tried to construct a sphere of self-sustenance by pillage of its occupied countries. Many government policies were necessary to construct this sphere of self-sustenance by pillage. It shows the particularity of Japanese imperialism in comparison with Occidental imperialist practices.

情報という言葉は今日広く使われるようになっており,この言葉の起源を調べた。森鴎外が明治20年前後クラウゼビィツの「戦争論」の翻訳に造語したのが最初と思われる。この言葉を用いた背景には福沢諭吉の思想も影響あったと思われる。その後軍事用語として用いられ,鴎外の小説にも出てくるが,一般の辞書に出てくるのは大正の終りから昭和にかけてである。軍事用語としては諜報の意味も含まれていたが,戦後は薄れた。一般に漢字という表意文字の組合せは,言葉から概念を規定することがあるので,情報という語の意味を漢字からも調べた。現在は各分野で学術用語としても多様に使われている。

The Aso-4 pyroclastic flow is one of the largest of late Pleistocene age in Japan covering extensive areas of Kyushu around the Aso caldera and western part of Honshu. We have recently discovered a distal ash which has very similar petrographic and chemical properties to the flow deposits at several localities of Japan, and is assumed to be an airfall part of the Aso-4 unit. The ash, named the Aso-4 ash, is a crystal-vitric fine-grained ash, consisting of rhyodacitic bubble-walled glass shards, and brown hornblende and orthopyroxene (bronzite) as mafic phenocrysts. Its identification is carried out by combined parameters ; refractive index of glass ranges 1.506-1.511, low refractive index of orthopyroxene (γ=1.699-1.701) and relatively high index of hornblende (n_2=1.687-1.688). In addition glass in the ash is characteristically rich in potassium. These properties are similar to those of the Aso-4 pyroclastic flows. It is suggested that the ash is a coignimbrite airfall deposit of fine-grained materials from the upper part of an eruption column formed at the same time as the Aso-4 flow. The ash mantles extensive areas from Kyushu to Hokkaido and is also recognized and identified in several piston cores from the Sea of Japan and the northwest Pacific Ocean. The fallout area of this ash is now known to attain approximately 4×10^6 km^2. It is striking that in the eastern part of Hokkaido, ca. 1700 km distant from the source, the ash with the thickness of 15 cm is well preserved immediately below the Kutcharo pyroclasitc flow deposits II/III. The bulk volume of this ash is estimated to be more than 400 km^3, possibly larger than that of the flow deposits. The stratigraphic position of this ash in standard sequence of South Kanto shows that it occurs after the Obaradai interstade (ca. 80 ka) and before the Misaki interstade (ca. 60 ka). Thus the Aso-4 ash provides a very important datum plane in late Pleistocene sequence in and around Japan.

At present, there are approximately 200 schools for foreign nationals in Japan. Among them, Chosen gakko, Korean schools, have a history of sixty years. In order to better understand Korean schools, it is necessary to research the culture of suchschools, the daily lives of teachers, students, parents, and their perceptions of themselves without paying too much heed to the political discourse. Through interviews of parents whose children attend Korean schools, this study examines why the parents chose to send their children toKorean schools as well as their level of satisfaction toward school. In conclusion, the reasons for their school choice varied depending on their own experience. For those who themselves attended Korean schools, it was a "natural" choice to send their children to the same type of school, just like most Japanese send their children to Japanese schools. On the other hand, those Koreans who attended Japanese schools themselves felt it took a longer time to establish their own identity by attending a Japanese school, thus chose Korean schools for their children. For both types of parents, the main reason for choosing Korean schools is to provide a safeenvironment where children have to struggle less with identity conflicts. The study also found a high level of satisfaction among the parents toward Korean schools.
