Analysis of lightning electromagnetic field using the FDTD method have been studied in recent year. However, large-scale three-dimensional analysis on real environment have not been considered, because the FDTD method has huge computational cost on large-scale analysis. So we have proposed a three-dimensional moving window FDTD (MW-FDTD) method with parallel computation. Our method use few computational cost than the conventional FDTD method and the original MW-FDTD method. In this paper, we have studied about computation performance of MW-FDTD parallel computation and large-scale three-dimensional analysis of lightning electromagnetic field on a real terrain model using our MW-FDTD with parallel computation.

In various sections of Japan, a number of popular beliefs and practices are centered around the day of metal and the monkey (koshin) in the old Chinese cyclical caldndar.Until recently it was generally thought that this cult was imported from China during the Edo period, but of late Japanese students of ethnography have propounded the theory that it is an indigenous Japanese phenomenon.In Chinese Taoism one finds the idea that in each person's body there live three noxious insects which try to shortened the person's life.On the day of metal and the monkey the insects are supposed to ascend to heaven and recount all the person's evil deeds to the god of life.The Chinese believe that if one stays up all night on the night of the day in question, the insects will not be able to go up to heaven, and one's life will accordingly be lengthened.Furthermore, there are various medicines and superstitious methods designed to exterminate the insects.The present author believes that the theory of the three insects as well as the methods of eliminating them were brought to Japan at an early date and became the basis of the Japanese koshin cult.An examination of Japanese koshin practices as seen in Oyabu, Mihama-machi, Mikata-gun, Fukui Prefecture, reveals a certain number of customs related both to Shinto and Buddhism.People stay up late at night somewhat as in China, but all in all there is little suggestion of the three insects, and one might be prone in this instance to suspect a Japanese origin.On the one hand, practices in other areas as well as statements in early Japanese documents make it virtually impossible to dissociate the Japanese koshin cult from that of the three insects.To illustrate this point, the author has in the present article enumerated around eighty Chinese methods of exterminating the insects and has compared them with means of extermination seen in Japanese texts.It is clear that the Japanese methods are almost entirely based on those of China.The Japanese cult as it appears today is completely different from the Chinese.The reason is that this foreign relgious element has been totally assimilated into Japanese culture.The author regards this development as excellent example of acculturation.

The purpose of this paper is to make clear the aesthetic thoughts of Poe and Baudelaire from the viewpoint of the imagination theory. Through this examination, we can find that their thoughts showed the peculiar views against the imitation theory in those days. Poe and Baudelaire consider that imagination has two functions : the first function is to find unexpected analogies among some ideas or things, and the second is, by the combination of these analogous ideas or things, to produce something novel and beautiful that is similar to the vision in the delirium. They insist that, by exertion of this imagination, artists should transform the composition of natural things. While Poe and Baudelaire take a similar view in these regards, we can also point out some distinctions between their imagination theories. What the distinctions may be, it is noteworthy that their imagination theories furnished arguments against the traditional imitation theory.

Already in the latter half of the 10th century a temple of the Shingon sect (Fukusho-ji) was established in Kazurahata, and after the Tensho Disturbance in the latter part of the 16th century this became a Shugendo temple. Within the temple precincts there was a hall dedicated to Koshin, and notwithstanding the abolition of the temple in 1895 the Koshin Hall remains to this day as an object of the fervent belief of the people. In his "Research Report on the Koshin Belief in Kazurahata" (1988), Osamu Nishimura states that the Koshin Hall was built in 1719. However, considering the fact that Koshin belief can be seen widely among the court nobles, and also the connection between Shugendo and Koshin belief, the author believes that the Koshin Hall was built at the same time that Fukusho-ji was converted to a Shugendo temple. Koshin belief and the festival of Kazurahata display various special characteristics and overflow with valuable legends. In particular, the fact that they exhibit ah unusual organizational structure, the fact that the daily life of the people and their beliefs are closely connected, the custom of seven-colored cakes and koshin konyaku, taboos concerning childbirth and menstruation, the legend of the Koshin cold, and the survival of the all-night vigil connected with the festival can all be pointed out as extremely unusual special characteristics.

美利河ダムでは, サクラマス (サケ科サケ属) の降下魚対策のため, ダム湖を迂回するバイパス魚道が計画されている. 魚道上端と河川の接続部には, 河川の水と魚をまとめて取り込み, 余水だけを戻して魚を魚道に誘導する施設が必要であった. 施設計画の技術的課題は, この目的に対して有効な余水吐き形式を設定することと, 魚をできるだけ迷入させない細部条件を設定することであった. 実際の魚を使った現地実験を踏まえて検討した結果, 余水吐き形式は横越流堤による薄層越流方式が有効と判断された. また, 有効な越流水深や横越流堤の形状, および照明の併用など, いくつかの設計条件が得られた.

On coral reefs, sites that receive consistently high levels of recruitment relevant to other sites (“recruitment hotspots”) may be crucial to the persistence of populations. However, few studies of coral recruitment have the necessary replication in space and time required to detect recruitment hotspots. The aim of this study was to detect recruitment hotspots at One Tree Reef (southern Great Barrier Reef) and to explore associations between hotspots, hydrodynamics, adult abundance and reef benthos. Recruitment hotspots were detected on the reef slope and in the lagoon. Almost all hotspots were located on the leeward side of the reef, however, there was little congruence among hotspots for different families of coral recruits. Recruitment hotspots in some taxa in some habitats were correlated with water flow or adult abun-dance. A clear recruitment hotspot for two families (Pocilloporidae and Poritidae) in the lagoon had medium levels of water flow (∼4 cm s-1), but there was no re-lationship with water flow on the slope. In experimental aquaria, Acropora nasuta settlement was six to 10 times greater under low (2.1 cm s-1) compared to medium water flow (4.6 cm s-1). Abundance of pocilloporid and poritid, but not acroporid, recruits at each site was often correlated with adult cover indicating either aggregative settlement or limited dispersal. Recruitment hotspots are likely to be both sources and sinks for some taxa, and therefore identifying and protecting hotspots should be a high priority in marine reserve design.

The concept of the ``wisdom of crowds'' has attracted attention for finding new insights by appropriately processing the large amount of information possessed by crowds. A prediction market is one estimating method that uses the mechanisms of financial markets such as stock or exchange markets to realize the ``wisdom of crowds''. In this study, we use agent-based simulation to clarify the condition that makes prediction markets effective. An artificial market is a virtual financial market run on a computer. Agents participate in them as computer programs that play the role of virtual dealers. In the simulation, we confirm the influence of the following parameters: information transmission frequency, the retention of motivation, and the gap of information recieve abilities. The results of this study suggest that prediction markets realize more accurate results than opinion polls under the following conditions: the gap of information recieve abilities and relatively low motivation.
