The west coast of Kii Peninsula and Shikoku, western Japan, suffered severe damage from the three Nankaido tsunamis of 1707, 1854 and 1946. There are many old monuments of the 1854 Ansei tsunami along the Kochi coast. Old documents on the Hoei (Oct. 28, 1707) and Ansei (Dec. 24, 1854) tsunamis along the southwest coast of Kochi Prefecture were collected during the present field investigation and illustrated in this paper. Based on the documents, the inundation heights of the 1707 Hoei and 1854 Ansei tsunamis were surveyed by handlevel and compared with those of the 1946 Nankaido tsunami (Dec. 21, 1946). The inundation heights (above M. S. L.) of the 1854 Ansei tsunami along the southwest coast of Kochi averaged 5.5 meters. Those of the 1707 Hoei tsunami averaged 7.7 meters with maximums of 10 meters at places. Although the inundation heights of the 1946 tsunami along the entire Pacific side of Shikoku were nearly uniform, the patterns of height distribution along the west coast of Shikoku for the 1707 and 1854 tsunamis differ significantly from those of the 1946 tsunami. The inundation heights of the 1854 Ansei and 1707 Hoei tsunamis on the western Shikoku coast were 1.5 and 2.1 times respectively, higher than those of the 1946 tsunami. This suggests that the rise times and/or the amount of the slip displacements on the west part of the fault might be different.

Yuasa and Hiro located on the west side of Kii Peninsula, western Japan, have been hit by many large tsunamis which were generated about every 100 to 150 years. Sources of all these tsunamis were offshore between Wakayama and Shikoku along the Nankai Trough. Traces of the inundated level on many houses in the two towns caused by the 1946 Nankaido tsunami (Dec. 21, 1946) were surveyed, using the automatic level from Oct. 18 to 23, 1982. The behavior of the 1946 tsunami run-up on land was investigated and compared with the two historical tsunamis of Hoei (Oct. 28, 1707) and Ansei (Dec. 24, 1854). The results of the present survey are as follows: (1) At Yuasa, the inundation heights of the 1946 tsunami were 3.0-3.5 meters above M.S.L. Ground about 3.0 meters above M.S.L. was inundated, so that 450 houses were inundated but hardly any were washed away. At Hiro, the sea wall strongly protected the main part of town from the 1946 tsunami (This bank was constructed just after the 1854 Ansei tsunami from Mr. Goryo Hamaguchi's personal funds). However, the tsunami energy concentrated at the head of bay along the Egami River. The inundation heights locally reached 5 meters (above M.S.L.) or more and 22 persons were killed. (2) According to old documents, the inundation area of the 1707 Hoei tsunami elongated along the Yamada, Hiro and Egami Rivers. Forty-one lives were lost at Yuasa and 192 at Hiro. Inundation heights above M.S.L. were estimated 4-5 meters at Yuasa and 5-6 meters at Hiro. (3) By the 1854 Ansei tsunami, 28 lives were lost at Yuasa and 36 at Him. The patterns of damage at Yuasa and Hiro are similar to those of the 1707 Hoei tsunami. There remain even now traces of the inundation level on a few old houses in both towns. Inundation heights above M.S.L. were 4.0-4.7 meters at Yuasa and 5.0 meters in the center of Hiro town. Ground about 4.0 meters above M.S.L. was inundated, 0.7 to 1 meter higher than that during the 1946 Nankaido tsunami.

寛文・明和日向灘津波および宝永・安政南海道津波について,史料をもとに大分・宮崎県沿岸各地を現地調査し,津波の高さ,浸水域の広がりを考察した.寛文津波は宮崎平野に広く浸水し,津波の高さは4~5mと推定される.明和津波は大分県沿岸で2~2.5mの波高があり,津波よりむしろ地震災害が上回った.津波マグニチュードは,それぞれm=2と1に格付けできる.両津波の震度・波高分布および地殻変動の記録を近年の日向灘津波と比べると,波源域はいずれも沿岸付近にあったとみなされる.一方,宝永南海道津波は大分・宮崎県沿岸各地の集落に溢れ,津波の高さは3~4.5mに達している.また,熊本・長崎県沿岸にも浸水記録があり,30分程度の長周期波が卓越したことを暗示する.安政南海道津波は宝永津波よりやや小さく,大分・宮崎県沿岸の波高は2~3mと推定される.両津波の規模および震度が1946年南海道津波を上回り,予想以上に九州各地に強い影響を与えていることから,波源域が1946年津波のものより四国の南西沖に伸びていたことを考えさせる.

In the mid-Edo period, the edehon produced by Tachibana Morikuni and Ōoka Shunboku were used in amateur painting education to research the technique of professionals. It is believed that the edehon provided professional illustrators with theopportunity to study the techniques used in conservative Kanō school tradition, classicalpainting, and Chinese painting, to which they would have had little access, andincorporate these techniques into their own works. This essay focuses on ukiyoe, a representative print art of Edo-period massculture, particularly the works of the Utagawa school of the late Edo period, in anattempt to present those pieces that suggest a reliance upon edehon. With this, it ispossible to suggest the diffusion of Kanō school painting techniques through edehon, and in particular, to discover the transmission through ukiyoe prints.

日本国内への外来雑草の侵入を明らかにする研究の中で,大量の雑草種子が輸入穀物から検出され,輸入飼料が雑草の侵入ルートの一つであることが確実となった。イチビ,ショクヨウガヤツリ,ワルナスビなど飼料畑の強害雑草となっている草種について,栃木県那須地域の20km四方の範囲で,GPSを用いて詳細な分布調査を実施し,分布パターンを解析した。分布パターンは草種によって大きく異なり,イチビとショクヨウガヤツリは農耕地に発生が集中し,アレチウリ,オオオナモミ,ブタクサは50%以上が非農耕地で発生が確認された。GPSデータは外来雑草の今後の分布拡大を地理的スケールで明らかにするためのデータベースとして利用可能であり,侵入植物に対する生物資源や生態系保護のための効率的な取り組みに活用できる。

More than 40 topographic highs resembling conical submarine volcanoes in the area between the eastern coast of the Izu Peninsula and the Izu-Oshima island, are identified by the detailed submarine topographic maps recently published. 17 dredge hauls were recovered from 26 dredge stations occupied during cruise KT78-10 of S.S. Tansei Maru of the Ocean Research Institute, University of Tokyo. Most of the rock samples are fresh basalts from the top part of the isolated peaks indicating that many of these topographic highs are young submarine volcanoes. They are very likely to be the submarine counterparts of the subaerial Higashi-Izu Monogenetic Volcano Group distributed on land just west of the dredge area. Most of them are high-alkali tholeiitic basalts with phenocrysts of olivine and plagiocalse. Augite phenocrysts may be present and some specimens contain abundant quartz and plagioclase xenocrysts derived from felsic plutonic rocks, a feature very similar to that found of the Higashi-Izu Monogenetic Volcano Group. Many are nearly aphyric and high in Al2O3 (19-17%) which is in strong contrast with the low alumina, low alkali tholeiites of Izu-Oshima island. In the Harker variation diagrasm, the highalumina, high-alkali tholeiites, both on land and under the sea, have distinctly high Na2O as compared with the basalts of Izu-Oshima. There seems no compositional gradation between the two although they are contemporaneous and occurring in adjacent areas.

The objective of this report is to investigate the pluralism and the compatibility among polyamorists, focusing on the gathering of a polyamory group in California and polyamory terms that are used by polyamorists. Polyamory means "responsible non-monogamy". It is best explained with the words: "honesty" , "consensus" and "responsibility". In fact, most studies about polyamory have pointed out that people who are recognized as polyamorist have various backgrounds, and the ways of practicing polyamory are extremely diverse and inconsistent. In this article, I look at polyamory in terms of a "contact zone" where people who have various thoughts and cultural backgrounds are interacting. I examine how polyamorists connect with each other in their contact zone. In order to achieve this purpose, "Cyborg Feminism" which is advocated by Donna Haraway is a key concept. Donna Haraway seeks a way of connecting that is not emphasized by homogeneity in "Cyborg Feminism". Cyborg is a body which holds multiple internal differences. Primarily, looking at the meeting of a polyamory group through the image of a cyborg suggests that polyamory has plural and comprehensive characteristics. Secondly, I examine the polyamory terms. The terms in polyamory are not only a tool of communication, but also a tool of self-accountability, one's relationship and the love they belong to. It implies that the ethical question of "How should I treat myself?" is shared among polyamorists. Polyamory is composed of multiple perspectives, and it is not a group which has only a single value system. There are blank spaces following the question "who are we?". However, the otherness and the blank space which polyamory holds are the possibility of critical self-forming with others.

In the Taisho era (early 20th Century), the “Ohisama” magazine was published by Shinzo Fukuhara, the second president of Shiseido (cosmetics company), during the “golden period” of publishing magazines for children when many magazines for children were started, including “Akaitori (Red Birds)”, which is known by its high artistic quality. In this paper, we closely investigated the history and contents of the “Ohisama” publication, and analyzed the activities of Fukuhara in the founding period of Shiseido from various perspectives, by examining the originality of the magazine as a medium for children and mothers. The findings of this study suggest that Fukuhara had the belief that disseminating richly varied high culture and lifestyles through this magazine for children would, long range, establish the corporate image of Shiseido to children and mothers.
