広島原爆に遠距離で被爆した花嵐岩中に自然発生した長寿命核種^<36>Cl (半減期3×10^5年) の量の正確な推定を行う上で必要となる情報を得るために, カリウム (K), ウラニウム (U) ならびにトリウム (Th) 含有率を天然放射性同位元素からのガンマ線測定を行い定量した。非被爆花嵐岩中のU, ThならびにKも定量し, それらが広島周辺の岩盤ごとにどのように変わるか調べた。定量結果から, たとえば愛媛県の伊予大島からの伊予石におけるKの含有率は広島市に近い倉橋島の議院石の含有率に比べて低い, などいくつかの興味深い事柄が分かった。議院石採石場の山頂近くにあった大きな岩盤の様々な深さから採取した17個の測定結果から, UとTh含有率が岩盤のある小さな部分で極めて高いことが分かった。その最大値はUの6.5ppm, そしてThの55ppmである。このことから, UとThの含有率は議院石採石場の中の位置によってかなり変化することが推察された。

This study examines how major newspapers in the world covered the 60th anniversary of the atomic bombing of Hiroshima by referring to the hegemony theory. This theory suggests that media content, especially international coverage, is influenced by historical views, the dominant public opinions, and the ideology of those in power in society. Qualitative content analysis is mainly used for this study. Data for this study consist of articles published between August 5 and 8, 2005, in newspapers in eight countries / region (China, France, Germany, Russia, South Korea, the U.K., the U.S., and the Arabic region). The findings generally confirm the existence of bias and differences in Hiroshima coverage across countries / region. Western European (France, Germany, and the U.K) newspapers criticized the bombing for aiming at civilians and presented it as an important moral lesson. American newspapers, on the other hand, generally depicted the bombing as a justifiable past event which has little significance in the present day. Chinese and South Korean newspapers focused mainly on the responsibility of the Japanese for having starting the war that ended up with the bombing. Different coverage on Hiroshima could be attributed to the difference in historical relations to and public sentiment on Japan, and other ideological factors.

The present paper is a sequel to our previous one entitled "Rivers and Bridges as First Places of Refugee at the Time of the Atomic Bombing of Hiroshima." Both in the previous and present papers, it is our belief that despite the vast research material and literature accumulated on the human damages and sufferings caused by the Atomic bombing on Hiroshima., there are a few missing pieces in the whole picture of the totality of the damages and sufferings. One such piece is the behavior of the sufferers on the day of the bombing before they arrived at some first aid station, relief station or hospital, or before they died. We know little about how they reached such places.In the previous paper, first we showed that rivers and bridges were first places of refuge for many people. And secondly, we explored how they fled, or failed to flee, to rivers and bridges just after the atomic bomb explosion, and extracted four typical patterns of behavior: failure, exhaustion, sojourn, and success.In the present paper, relying on the same data and method as before, we begin where the previous one ended, and examine how people crossed (or failed to cross) a river or a bridge after they arrived there.The examination shows that the refugees who managed to arrive at a river or a bridge were faced with two major options. They could try either to cross the river, or the bridge. In the former case, they could try to walk or swim across the river, or to cross it by a boat. In addition, they might choose to stay where they were for various reasons, or they might take refugee in the river water, especially from the approaching fire.In all these choices, we find cases both of failure and success. But, we also find cases where refugees dissuaded themselves from trying to cross the river or bridge, presumably at the sight of so many tragic failures.Ours is an attempt at shedding some new light on the hitherto unexplored aspect of the human damages and suffering caused by the atomic bombing on Hiroshima.

This thrust of this essay is to consider the changes and the relationship of the various infl uences in Hōgai’s works through a comparison of two works, Kannon with Hibo Kannon, and an analysis of Niōsokki. From an analysis of these works, the newness of Hōgai’s later works can be seen in his technical use of ink painting and colour painting. Two other examples unrelated to motif are the uniformity of his brushstrokes and an expressive “smearing”. Hōgai’s late works refl ect a wide range of elements: designs inherited from the early Edo period, the infl uence of techniques that appeared at the end of the Edo period and early Meiji period, techniques from Western painting, and Fenollosa’s theories. The relationship between Hōgai and Fenellosa cannot be reduced to the simplistic statement that “Japanese culture had changed after the acceptance of Western culture”. It should, I suggest, be seen as a mutual exchange. Hōgai’s late works can only be understood as the product of a cultural exchange of multiple periods, places and people

The aim of this paper is re-construct a fire field near epicenter of Hiroshima A-bomb in 6 August 1945. For this purpose, we used the official records in Hiroshima Genbaku Sensaishi (Hiroshima A-bomb Damages) and plotted spot (town)-specific fire status on a map in order to visualize easily. Our visualized map showed that fires in 21 spots started just after dropping A-bomb and the fire spread with the passage of time. Finally, the fire started in most of the spots of the area within a radius of 2 km of the hypocenter by approximately 15:00. The fire in ten spots was not putout during August 6. The area was on the east side of the Hiroshima city.

第二次大戦とその後の米国による日本の占領とも対比して、9-11(テロ)とその後のイラク戦争に翻弄される米国を歴史家の観点から批判した歴史家ジョン・ダワーによる労作の書評。本書評では、非戦闘員の殺戮という行為が、正当性を認められた過去の戦争で如何に恒常化してきたかに焦点をあて、本書の題名の意味するところを明らかにしようとした。

In this paper, we present a framework to construct message recovery signature schemes from Sigma-protocols. The key technique of our construction is the redundancy function that adds some redundancy to the message only legitimately signed and recovered message can have. We provide a characterization of the redundancy functions that make the resulting message recovery signature scheme proven secure. Our framework includes known schemes when the building blocks are given concrete implementations, i.e., random oracles and ideal ciphers, hence presents insightful explanation to their structure.

Accumulated external radiation doses of residents near the Semipalatinsk nuclear test site of the former USSR are presented as a results of study by the thermoluminescence technique for bricks sampled at several settlements in 1995 and 1996. The external doses that we evaluated from exposed bricks were up to about 100 cGy for resident. The external doses at several points in the center of Semipalatinsk City ranged from a background level to 60 cGy, which was remarkably high compared with the previously reported values based on military data. INTRODUCTION A total of 459 nuclear tests were conducted by the former Union of Soviet Socialist Republics (USSR) between 1949 and 1989 at the Semipalatinsk nuclear test site (SNTS) of Kazakhstan, including 87 atmospheric, 26 on the ground, and 346 underground explosions1). The total release of the energy equivalent of trinitrotoluene (TNT) of about 18 Mt was eleven hundred times that of the Hiroshima atomic bomb. However, previous reports concerning the effects of radiation on residents near the SNTS based on data provided by the Defense Department of the former USSR2, 3) did not involve direct experimental data concerning the effective equivalent dose. They just measured some doses for particular settlements after some nuclear explosions. These did not indicate an integrated dose of the residents of all the explosions. The technique of thermoluminescence dosimetry (TLD), which had been successfully applied in dosimetry for the Hiroshima and Nagasaki atomic bombs4, 5), enabled us to evaluate the accumulated external gamma ray doses of all the nuclear explosions at specific places in the Semipalatinsk test site. The TLD technique is well-established not only for instantaneous exposure as in A-bombs (Hiroshima and Nagasaki)6) but also in prolonged exposure to natural radiation, which is used in dating7). Moreover, this technique was applicable for dosimetry studies of radioactive fallout as shown in studies of the Chernobyl accident8,9).

セルアニメーションにおけるキャラクタは、非現実的な動作や変化といった現実の人間とは異なった描画のされ方をしている。しかし、その描画は視聴者に大きな違和感を与えない場合が多い。すなわち、ただ単純に3DCGモデルを画面に投影したものとは異なるが、見る者に違和感を与えないような描画のされ方をしている。本稿ではキャラクタの振り向き動作時の顔の描画の分析をするために作成した、フレーム毎に顔の各要素の特徴点位置を記録するプログラムについての報告と、要素間の距離変化の分析の報告を行う。
