第一報において,火山灰と皮脂汚れとの混合汚れの洗浄において,硬度の影響が大きいことが認められたことを報告した。ここでは,硬度成分と考えられる火山灰中の各元素を含む鉱物が洗浄に及ぼす影響と鉱物の変化と洗浄の関係,さらに商業洗濯における再汚染の有無を明らかにすることを目的とした。原子吸光法による火山灰の分析の結果,ケイ素,アルミニウム,鉄,マンガンの順に鉱物は多く含有されていることがわかった。この鉱物の中で,アルミニウムが最も繊維に付着しやすく,洗浄効率が低いことがわかった。マンガンの含有量は少ないが,付着すると非常に落ちにくい物質であることもわかった。白布添付による方法で再汚染試験を試みた結果,ドライクリーニングにおける再汚染はほとんどないことが明らかになった。

The intergeneric hybrids which have been produced by the artificial breeding between Salmo trutta and Salvelinus fontinalis are usualy called "Tiger trout" or "Zebra" in Europe and America, because the colour markings on their body surface resemble the stripes of these animals. These hybrids produce rarely under natural conditions in the river, where the both species intermingle. (James.H.Allan, 1977) In Japan, however, this natural hybridization has scarcely been reported in the past. On 24 September 1978, a single specimen presumed to be one of "Tiger trout" hybrids was caught from the upper streams of Taishoike Dam, where Salmo trutta and Salvelinus fontinalis suspected its parental species were crowding together. Since 1975, about 300 specimens of Salmonid fishes have been caught and examined during our studies of the Taishoike areas. Of all these specimens collected during these 20 years, 102 were Salvelinus fontinalis and 47 were Salmo trutta. However, only one specimen presumed "Tiger trout" hybrid was caught. Therefore, this hybrid constitutes about 0.7 per cent of the total population of parental species: Salmo trutta and Salvelinus fontinalis. The author attempted to ascertain whether or not such a specimen is really a hybrid from these two species, and to analize the factors for natural hybridization in Taishoike Dan. The present specimen was male of 3+ years age, 166mm in body length (195mm in total length), 38mm in body breadth, 52.5g in weight, and its milt weighed only 0.4g in the early spawning season. It had golden brown colour with broad, dark brown vermiculations on the lateral surface, dark brown spots on the dorsal and adipose fins. It doesn't seem to look like either of its parental species. Some measurements of the numerical characters of this hybrid are as follows: 110 scales on lateral line, 15 gill rakers on 1st arch and 57 vertebrae. These measurements showed that this hybrid specimen is between Salmo trutta and Salvelinus fontinalis. The characteristics of the present hybrid are similar to those shown in the photograph and the description about the "Tiger trout" (Salmo trutta ♀×Salvelinus fontinalis♂) by Suzuki; Fukuda (1973), except a little difference. From these facts, it is evident that this natural hybridization occured from the intercrossing of Salmo trutta♀ and Salvelinus fontinalis ♂. Since 1925, the eggs and fry of Salmo trutta and Salvelinus fontinalis have been imported into the Taishoike areas from North America and Inawashiroko Lake and others. Especially, the local fishermen continued to stock this water area with Salvelinus fontinalis untill 1971. Since then, both species have increased in number. Although the opportunity for natural hybridization may be fairly frequent, the hybrid produced by such intergeneric crossing as Salmo trutta × Salvelinus fontinalis is rarely to be found in the natural environment due to low fertility of parental species, and low survival rate of F_1-hybrifds. Moreover, these F_1-hybrids "Tiger trout" produce neither fertile eggs and milt, and so they are all sterile. (Suzuki;Fukuda, 1971・1973) Because of these facts, this hybridization may exert very little influence upon the normal reproduction of Salmonid fishes in these natural water areas.

This paper describes a human skeleton from a rock-shelter in northeast Laos, dated to ~7000 BP. It was excavated in 2004 and moved en bloc to the Laos National Museum in Vientiane. Here we report observations made from the in situ skeleton. The burial is the largely complete but slightly damaged remains of a tall, middle-aged, probable male buried on his side in a flexed position. His teeth were heavily worn and one was infected but otherwise there is no evidence of poor health. We were not able to make an assessment of biological affiliation. In comparison with the very small samples of approximately contemporary skeletal remains from the wider region around the middle Mekong, it is clear that the burial position and dental health were not unusual, but that he was very tall for that period of prehistory.

The author has carried out a ten-year project on science, technology and society in postwar Japan during which he looked into the publishing activities of the industrial, governmental and academic sectors. Till the 1970s science and technology journalism aimed at rendering science and technology understandable to the general public; later however, it focused on issues that became the concern to the general public such as pollution. The author describes the various stages science and technology journalism have gone through, from its incipient role in the nineteenth century when it was used as a way to enlighten the general public and as a public relations tool for the scientific community, to the atomic age when journalism became aware of both the positive and negative aspects of science and technology by remained at a loss on how to go about reporting it, to the space age when enlightenment aim became predominant again, to the antipollution campaigns that used the visual mass media to great effect, to the debate on gene recombination with scientists addressing the general public on the issue. Science, the author points out, needs now feedback from the general public since it has acquired a new and expanded ability to control people's lives.

フタル酸ジエチルヘキシルのような準揮発性有機化合物(SVOC)は,喘息だけでなく化学物質過敏症の原因になっている。室内空気中のSVOCは,蒸気圧が低いために単体の分子(ガス相)あるいは,浮遊粉じん上(粒子相)の双方に存在する。しかし,これらの分配係数の測定法が必ずしも確立されているとは言い難い。そこで本研究では,超音波アトマイザで関東ロームの試験浮遊粉じんを発生させて,拡散チューブを用いてガス相および粒子相のDEHPの分離測定を行うことを試みた。その結果の1つとして,特定の条件下においてガス状DEHPの試験浮遊粉じんへの吸着特性はラングミユア型を示すことが示唆された。

Fault activity in the Yoro–Kuwana–Yokkaichi fault zone is considered to have been the source of the 1586 Tensho Earthquake. The Geological Survey of Japan conducted array boring and trenching surveys at Hazawa and Niwada within the ~30-km-long Yoro fault system, which is the main component of this major fault zone. This paper reports the main results of these surveys, focusing on the most recent faulting events and with new paleoseismological data.<br>At Hazawa, the boundary between prodelta and delta-front sediments formed within the Kiso River system at around 4 ka has been displaced vertically across the fault by about 15 m, and the top of the deltaic sediments formed at around 1.7 ka by ~10 m, indicating repetitive fault activity since 4 ka. The floodplain on the up-thrown side of the fault has been terraced since about the 8th century; this probably reflects the penultimate faulting event. The last event occurred after the 8^th century.<br>At Niwada, four offlapping sedimentary units separated by angular unconformities are capped by a buried soil or peat layer containing abundant plant fossils and charcoal fragments that have provided C-14 data to constrain the timing of faulting events. At least three episodes of fault activity have produced cumulative tilting during the period of stable sea level over the last 4 ka. The last two tilting events occurred after the 15^th century and around the 8^th century.<br>The most recent faulting events on the Kuwana and Yokkaichi faults occurred after the 13th century. Furthermore, the two most recent rises of relative sea-level probably reflect coseismic subsidence on the Nobi plain about 500 and 1200 years ago. It is highly likely that the Yoro–Kuwana–Yokkaichi fault zone produced both the 1586 Tensho and 745 Tenpyo earthquakes, although geological data alone is insufficient to determine the exact age of these events.

The present article takes up a group in modern Japanese society "educated idler" (hereafter EI) (koto-yumin 高等遊民), whose members were highly educated but were not in social position proper to high educational background. The author examines the group's origins, structure and how it came to be perceived as a social problem. During the last years of the Meiji Era, in the aftermath of the Russo-Japanese War, the ranks of the EI was increasing by some 20,000 members per year due to such factors as "entrance problems" "lack of employment opportunities" and "dropping out" on the middle school level, as well as a "shortage of jobs" for graduates of technical colleges and universities. The author first attempts to place those EIs who had no visible means of support within the context of the state order by first examining pre-War newspaper reporting about "unemployment" and political concerns over the "dangers" of socialist movements, then describes the post-War attempts at state reorganization in the form of educational reform implemented by the Second Katsura Cabinet, resulting in an increase in the number of schools. However, reform efforts met with opposition in the midst of worsening conditions and were scaled down. With the occurrence of the "High Treason Incident of 1910" (Taigyaku Jiken), involving an alleged socialist plot to assassinate Emperor Meiji, and the subsequent arrests of hundreds of activists, the perceived "threat" posed by the EI and the Superintendent General's comment to crack down on it drew public opposition, resulting in a national debate over the social consequences of the EI. The author's analysis of the debate includes the media's understanding of the EI as a problem related to the social structure,the many reports documenting the lives of EI members ranging from literary figures to slum dwellers and criminals, as well as solutions calling for the dampening of lofty youthful ambition by putting young people to work. After placing the EI as a historical phenomenon characteristic of society in the post-Russo-Japanese War era, the author concludes that the educational and social policies implemented were not sufficient to solve the problem, and that the EI disappeared temporarily in the course of the economic boom generated by World War I, but reappeared during the expansion of higher learning institutions during the early Showa Era
