Oyaguchi Watersupply Tower, which was established by Aratama Municipal Union for Watersupply, has been known as one of the unique landmarks in the northwest area in Tokyo, but the Watersupply Bureau of Tokyo Metrpolitan Government decided to renew the structure according to their new plan for watersupply in case of emergency. This tower was planned by Eiji Nakajima, Dr.Eng., and designed by his successors after changes in two times. Its design consists of unified body of water tank and tower, and it was constructed by applying quasi-arc welding method, which was cutting-edge technology at that time. It was proved also that its form and details have an architectural style called Romanesque to make itself look.unique.

2012年9月から2013年4月にかけて、日本海沿岸で196個体のウミガメ類が漂着した。混獲された個体などを合わせると243個体となり、例年にない数のウミガメ類が発見された。種別の発見数はアカウミガメ151個体、アオウミガメ61個体、タイマイ17個体、ヒメウミガメ4個体、ウミガメ科の雑種4個体、オサガメ3個体であった。本研究で特に注目したのは、当歳幼体とここでは呼ぶ、甲長10 cm前後の孵化後数ヶ月のアカウミガメであった。アカウミガメ当歳幼体は107個体が漂着し12個体が混獲されており、ウミガメ類発見数の大半を占めていた。これらアカウミガメ当歳幼体は、mtDNAコントロール領域における~820塩基対より決定したハプロタイプの出現頻度から、沖縄や沖永良部産で、一部屋久島産が含まれることが示唆された。これらの個体が日本海に流入し始めたのは混獲の目立ち始めた10月から11月にかけてだと考えられ、水温の低下に伴い12月から1月になって日本海の海岸線に大量に打ち上げられたと推察された。水温の低下する冬季の日本海はウミガメ類の生存には厳しい環境であるとも思われるが、中には津軽海峡を通って太平洋へ抜けたであろう当歳幼体もいた。日本海に入ることはアカウミガメの当歳幼体にとって必ずしも無効分散ではないのかもしれない。

ビタミンA欠乏マウスの腸間膜リンパ節樹状細胞(MLN-DC)は、IL-13を高産生する炎症性T細胞を誘導することを見出した。ビタミンA欠乏マウスでは経口抗原に対する抗体産生がIL-13依存的に亢進していた。そこで、ビタミンA欠乏状態によって、MLN-DCに機能変化をもたらす腸管環境因子を探索したところ、近位結腸粘膜組織でTNF-αが高発現していることを見出した。以上の結果から、ビタミンAは腸管環境とDCの機能発現を制御し、腸管粘膜における免疫寛容の誘導に極めて重要であることが示唆された。

The purpose of meditation is to obtain a cessation of suffering along with the alteration of consciousness. While the ideal developments of mind and the positive outcomes of meditation are exclusively discussed in the Buddhist texts, the Visuddhimagga and Pāli commentaries notice the actual problems such as ten kinds of ・ impediment (palibodha) which the meditator need to sever before starting meditation and the eighteen kinds of unfavorable monasteries, which are called fault (dosa). A noisy environment created by worshipers and others hinders the meditator from concentrating his mind. External stimulation does not only break up the meditation, but sometimes provokes rather unpleasant reactions. Improper conditions, both physical and mental, during the meditation also have a mischievous influence on the meditator’s mind. Imbalance of five faculties also induces mental disorders. When unpleasant reactions appears in a meditator’s mind, one of the effective method of selfcare solution is considered to be scolding, talking to, convincing himself and pulling him back to the ordinary perception. In this paper, we consider the methods of handling such troubles during the meditation in Theravāda Buddhism.

Karyotypes of three spinous loaches, Cobitis biwae, C. taenia taenia and C. taenia striata from western Japan were investigated. As the result, chromosome polymorphisms and polyploid (tetraploid) were observed in these species. (1) C. biwae: Diploid specimens showed 48 chromosomes in 2n number. There were three types in chromosome constitutions such as 22M+20SM, ST+6A, 20M+20SM, ST+8A and 20m+18SM, ST+10A. On the other hand, teraploid specimens were characterized by 96 chromosomes which consisted of 38M+54SM, ST+20A. (2) C. taenia taenia: Diploid specimens with 50 chromosomes were characterized by 12M+4SM+34A. In the tetraploid forms, two types of individuals with 86 and 94 chromosome numbers were foud. These complements were made up of 32M+32SM, ST+22A in the former, and 26M+32SM, ST+36A in the latter. (3) C. taenia striata: Diploid form was the same as that of C. taenia taenia, whereas tetraploid form possessed 98 chromosomes consisting of 20M+22SM, ST+56A. (4) The geographical distribution on each group with different karyotypes showed that they have their own habitats forming respective isolated associations. Systematics and speciation in three species of Cobitidae were discussed on the bases of the karyotypic differentiation and habitat segregation.

「壬申の乱に敗れたのち,大友皇子は房総の地に逃げ延びた」という房総・弘文天皇伝説は,房総の伝説のなかでも傑出したものの一つである。このような伝説が成立した背景には,この地域が古代の製鉄民族,多(オオ)氏の支配地域だったことと関連していて,大友皇子のゆかりの人々がオオ氏を頼りに房総に移住したと考えるのが最も理にかなっている。それはまた,「田原」地名の分布にはっきりと刻印されている。田原とはタタラであり,製鉄が行なわれていたことを示しているのである。だが古代の末期から中世にかけて熊野修験道が流入し,その結果,オオ氏の祀っていた田原神は白山神へと姿を変えた。これが,現在の白山神社(君津市俵田)に物理姫と弘文天皇が祀られている理由である。

Tamano City of Okayama Prefecture, as a case of studies in industrial area, is treated here. The city is a mono-industrial city centering at Mitsui ship-building yard and grew up through it. To begin with, it unexpectedly began to show germination of growth as a local city since Mitsui ship-building yard was established in March of Taisho 8 (1919); though habitants of this area had been engaged in farming and fishing, by that time, by using limited plain and its back hilly land of granite on the Inland Sea of Seto. Main factor in the location of ship-building yard seems to have been various economic conditions that based on the policy of management in Mitsui Capital, and the natural and cultural conditions in this region. After that, in accordance with the changes of international and internal economic situation, prosperity and decay in turn had successively occurred according to the growth of ship-building. These situations also were related directly to the growth of Tamano city. Peculiarities of production structure that ship-building had in itself, soon became to reflect on Tamano mono-industrial city just as it was. Houses of workers were built up, and having these dwelling houses as their object, some shopping streets were formed, for many work-men were gathered around the village which was once out-of-the-way. And then, road-repairing and road-project were so smoothly and rapidly performed that the land features were in comparatively a short time changed village into town, town into city. With the progress of settlement, a bigger change was seen on the interior structure. Among the present population of 60, 000, for instance, ten per cents of the population are exployed in this ship-building yard. Bearing this fact in mind, you can easily understand that this city forms a close relation with ship-building business.If you consider the relations of all the kinds of correlated and subcontract industries and temporary workers and out-side workers characteristic in ship-bluilding, this relations will be more emphaticaly recongized. Prosperity and depression of ship-building business immediately mean those of Tamano city itself. Well, in the case of such mono-industrial city, there are also many faults exist for its too much acute reliance on ship-building: for good examples, the growth of correlated industries is stagnant, and the classification of labor structure in the ship-building makes its appearance in the order of civic social life as it is etc. In Japan, it is not too much to say that most of the local industrial cities have more or less similar phenomena. The author considers that these kinds of studies have to be made more actively, for the regional structure in Japanese industry must be more widely understood.
