Adding tsunami data reported by the U.S.S.R. sources, tsunami magnitude and the source area of the tsunamis generated in the Hokkaido and Kurile regions during the period from 1893 to 1978 are re-examined. The source dimension and magnitude of the tsunamis generated in the Hokkaido region correspords well with the earthquake magnitude. However, the tsunamis in the Kurile region have varied behaviors. The two Kurile tsunamis of Oct. 20, 1963 and June 10, 1975 were especially abnormal in comparison with other tsunamis accompanied by similar earthquake magnitude. In most cases, the initial motion of the tsunamis was observed with upward direction, but the Kurile tsunamis of Aug. 11, 1969 and June 10, 1975 began with a conspicuous downward motion at the Hokkaido and Kurile tide stations. The source areas of the tsunamis that accompanied large earthquakes (M>8) line up along the continental slope near the Kurile trench and the 1973 Nemuro-oki tsunami was generated in the seismic gap between the 1952 Tokachi-oki and the 1969 Shikotan earthquakes. However, the source area of the 1973 tsunami occupies only the eastern half of the 1894 tsunami source. After the 1973 Nemuro-oki tsunami, the tsunami activity moves to the northeastern direction along the Kurile trench. These source areas fall in the southern part of the source areas of the 1958 Iturup and the 1969 Shikotan tsunamis. In the space-time diagram of the earthquakes having a magnitude of M≧7, remarkable gaps can be seen in the west side of the 1973 tsunami source and off Urup Island. It is possible that a future tsunami of magnitude m~2 may be generated, accompanying the release of seismic energy in the two regions.

A serious earthquake eccurred in the north-eastern part of Tottori prefecture. The loss of life ammounted to 1117, severely wounded 669, totally destroyed houses 7485 and burned houses 251(statistics for Sept. 17, 1943) The damages were related to the river basin; about 80% of these damages were done in the basin of Hukuro-gawa(river) in the city of Tottori.

The air-gap capacitance-voltage characteristics of InGaAs surfaces were measured after 1-, 2-, 6-, 9-, and 17-cycle atomic layer deposition (ALD) Al2O3 processing. A high density of mid-gap states was found to be generated and increased during these ALD process steps, while the native oxide component was reduced. On the other hand, the mid-gap state density was drastically reduced after the usual annealing process. The generation of the mid-gap states seemed to be relevant to a non-stoichiometric Al-oxide component associated with a deficit in oxygen atoms, which became re-oxidized during the annealing process.

This article discusses the chronological development of EU's energy security policy and its problems. Because energy security is primarily a responsibility of national governments, the European Union (European Commission in particular) was not able to formulate unified energy policy. But at the same time, due to the lack of natural energy resources, EU member states needed to cooperate in order to increase bargaining power against energy rich regions such as Middle East or Russia. The problem of international negotiation became clear when Russia and Ukraine increased the political tension, and in order to secure supply of natural gas from Russia, EU launched the discussion with Green Paper which resulted the first comprehensive energy policy in 2007. Furthermore, the "Energy 2020", a new policy document suggested the necessity for EU to influence the process of rules- and standard-making to secure the free trade environment for energy resources. However, the division of competence between member states and EU still make it difficult to formulate comprehensive energy policy. Furthermore, dynamic change of international environment such as "Arab Spring" and Russo-Ukraine conflict, and different reactions and interests of member states complicated the EU strategy for energy rich regions. This structural contradiction of EU's energy security policy implies that EU may not be hegemonic power in international arena, but their role as a giant consumer of energy would have a power to shape international energy market.

Three experiments were conducted to investigate the processes of the mathematical problem-solving using juice-mixing problem. The results indicate that the error patterns are not consistent among the problems that have the same mathematical structure, the conceptual bugs in the mixing schemata determine the availability of the values of variables in the problem and the informal knowledge of "thickness" obtained through everyday experiences interacts the subjects' strategy choice. Detailed protocol analysis revealed that the informal knowledge of "thickness" has critical roles to monitor the results and to generate the elaborated internal representations during the course of solving the problem.

Feeding behaviour in the natural situation and dental morphology of 13 Tanganyika species belonging to 6 genera of algae scraping cichlids were studied to understand the degree of specialization for algae feeding in relation to size. Three parameters, speed of grazing (SG), successive repeated times (SRT) and time interval of browsing (TIB), were measured to analyze the behaviour. The fist two parameters were applied to 6 species of Petrochromis, grazers and the third one to 7 other browsing species. Among grazers, Petrochromis polyodon is regarded as the most adapted and P. fasciolatus as the least adapted to grazing diatoms off the filamentous algae. Among browsers, Telmatochromis temporalis has distinctive behavioural and morphological features, showing the lowest degree of adaptation. The other 6 browsing species share similar features. Limnotilapia dardennei and Simochromis diagramma show a lower degree of adaptation. Tropheus moorei can be regarded as the best adapted to browsing filamentous algae by shearing. S. babaulti and S. marginatus are situated between each of them. Pseudosimochromis curvifrons seems to diverge into browsing by cutting, not shearing. TIB can be regarded as a handling time. The validity of the "jacks-of-all-trades" hypothesis is discussed.

小笠原父島における津波記録を収集し,その挙動を考察した.二見港の奥村では,1854年安政東海津波で集落の大部分が流失し,津波の高さは3~4mに達したとみなされる.また,1918年ウルップ(南千島)津波で全振幅2.7mを記録し,19戸が浸水被害を受けた.津波マグニチュード判定図によれば,父島ではフィリピン・ハワイなど南西・南東方向から入射する津波に対して,標準的な振幅で観測されている.しかし,日本近海でおきた津波では,いずれも顕著な波高になり,平均津波マグニチュードより1~1.5階級の偏差(エネルギーで5倍,波高にして2.3倍以上)がある.その要因のひとつとして,小笠原諸島は屈折効果で,津波エルギーが集まることが津波伝播図から認められた.東海地域の津波に対しては,さらに津波の指向性を強く受ける方向にあり,将来の東海地震においては津波に十分な警戒が必要である.
