<p>This paper studies the <i>Hosshinshū</i>, <i>Shasekishū</i> and <i>Tsurezuregusa</i> in relation to Tendai <i>hongaku</i> philosophy. The following results are obtained. Firstly, the <i>Hosshinshū</i> is not affected by Tendai <i>hongaku</i> philosophy. Its stance detests this impure world and encourages seeking rebirth in the Pure Land. The <i>Shasekishū</i> has the idea that everyone can reborn in the Pure Land. However, it does not contain the idea that this real world is a manifestation of Buddha. Finally, the <i>Tsurezuregusa</i> accepts the real world. It finds the truth in the real world and might be affected by Tendai <i>hongaku</i> philosophy.</p>

本稿は、室町後期(一五世紀後期)から織田権力期(一六世紀後期)までを対象として、堺における自治および支配の構造とその変容過程を検討したものである。当該期は中近世移行期として「荘園制から村町制へ」というシェーマが示されているように社会構造が大きく変容する時期である。堺においても堺南北荘の存在や、近世都市の基礎単位になる町共同体の成立が確認されており、これらの総体としての都市構造の変容の追究が必要であった。検討の結果、堺南北荘を枠組みとする荘園制的社会構造から町共同体を基盤とした地縁的自治構造が主体となる社会構造への移行が確認され、その分水嶺は地縁的自治構造が都市全体に展開した一六世紀中期であった。そしてこの時期に、そのような社会構造の変容と連動して支配権力の交代、有力商人層(会合衆)の交代といった大きな変化が生じ、イエズス会宣教師が記した堺の「平和領域性」や自治の象徴とされる環濠の形成は、当該期の地縁的自治構造(都市共同体)の展開が生み出したものであると考えられた。そして、様々な部位で変化を遂げながら形成された一六世紀中期の都市構造が、近世的都市構造として一六世紀後期以降に継承されていくと見通した。This paper examines the feudal and autonomous regimes and their shifts in Sakai from the late Muromachi period (the late 15th century) to the period of the ascendancy of Oda Nobunaga (the late 16th century). This century was a transitional period from medieval to early modern, when the social regime changed drastically, as represented by the shift from the manorial system to the township system. Likewise, in Sakai, it has been observed that after Sakaikita-shō and Sakaiminami-shō (Northern and Southern Sakai Manors) were established, township communities emerged as the basis of the early modern city. Thus, it is important to inquire into the process of changes in the municipal regime to reveal how these basic units were integrated and developed into a new municipal regime.The results of the analysis indicate a shift from a feudal regime based on the manorial system developed under the framework of Sakaikita-shō and Sakaiminami-shō to a society characterized by territorial autonomy based on township. The watershed in this shift was the spread of the autonomous territorial regime around the city in the mid-16th century. This shift in the social regime was accompanied by major changes, such as the change of authorities and the replacement of dominant merchants (egōshū). The development of the autonomous territorial units (town authorities) at that time also seems to have contributed to the construction of moats as a symbol of autonomy as well as the development of Sakai into a "place of peace," as a missionary of the Society of Jesus described it. Moreover, this analysis suggests that the municipal regime which had been established and changed in different ways in the mid-16th century formed the basis of the early modern municipal regime in the late 16th century and thereafter.

スクリーンスケイプはスクリーンの映像だけではなく,その背後にあるさまざまな事象とその構造を含んだ概念である.この概念を用いることで現実の空間とサイバースペースの垣根を越えた研究が可能であり,双方の空間にわたる情報化社会にアプローチすることができる.映像の背後には技術,マーケティング,社会状況,コミュニケーションの4種類の要素がある.本稿では2Dのビデオゲーム空間の視点に注目した分析と聴き取り調査を行うことで,主に技術やマーケティングに関する調査を行った.その結果,コストと技術の制約の中でクリエイターは性能を最大限に活かす努力を行ってきたこと,技術の発展に伴い,ビジネスモデルが複雑化し,マーケティングの影響が徐々に強くなり,ビデオゲームの内容も変化したことが分析できた.このように,技術とマーケティングの影響を受けつつビデオゲームのスクリーンスケイプが発達したことが明らかになった.

1) Almost all the so-called modern interpretations of Plato's idea tell us that the idea is nothing other than a general concept It is true that Plato endeavours to find out the general concept for the benefit of science against subjective opinion (δοξα), but it does not imply that his sight does not reach the transcendent, which is the real object for philosophy Through philological analysis and philosophical reconstruction of Plato's original texts, the author concludes, in opposition to the currently accepted interpretation, that Plato makes an effort to discriminate ειδοζ as the universal, and ιδεα as the transcendent, the transcendent being often modified by the phrase αυτο το Such an inclination in the use of words is clearly perceptible both in Plato's dialogues after Phaedo and in the various texts of his successors, Aristotle, Theophrastus and later Neo-Platomsts 2) The necessary condition of true judgement is that the predicate is not subjective but objective, not individual but general Such generality depends on the nature of the thing which is intentionally designated by the subject-term in question, namely, the immanent form of the thing, that is to say ειδοζ which itself consists in genus-species-relation, and which, therefore, is determined in definition So the ειδοζ is no doubt μαλιστα οργανον for the science in general whose construction is a system of definition 3) But there is something which may not be comprehended by definition For Socrates can never succeed in dialogues in finding out the perfect definition for the real value such as beauty, or virtue such as justice (Meno 100 b 7 etc) We realize here that there is something which is super-ειδοζ, trans-ειδοζ, "au dela de" ειδοζ, επεκεινα τηζ ουσιζ, that is to say ιδεα 4) Through strictly philosophical reflexion, which may not be summarized here, the author enumerates the following kinds of ιδεα a) The ground or criterion of thought and judgement, such as το ισον (equality), το μεγα και μικρον (great and small) (Phaedo 75 c 1-2, etc) b) Ideal form of natural beings, referred to in Timaeus (Tim 39 e 7-9, etc) c) The highest prime cause of cosmological dynamics (Phileb 27 b 9-cl, etc) d) The real value such as Beauty, Good, One, Justice etc e) Some artefacta (artificial things) which have essential relation to βιοζ θεωρητικοζ or βιοζ θειοζ (Arist Met 1070 a 18-19, Resp 596 b 3-4, Soph 265 e 3-4, Phaedo 62 b 7, etc ) But all such kinds of idea are condenced in, or included by, that mentioned in c) above, namely, the real transcendent that in nature is God 5) The idea of the Good ιδεα του αγαθου as αρχη will, according to Plato's own text, be apprehended only after the dialectical speculation through ειδοζ (Resp 510) This transcendentality of idea is confirmed by the analysis of Plato's VIIth letter (VII Epist 342 a 8-e 2)

La teoria ficiniana dell'ars non e una 'teoria delle Belle Arti'. Ars e, come la parola greca techne, il sapere produttivo in senso esteso che include anche il lavoro artistico. In questa ricerca della teoria ficiniana dell'ars ci limiteremo alla sua opera maggiore, Theologia Platonica(TP). TP tratta di 5 gradi di essenze : Dio, angeli, anima(uomo), qualita, quantita. L'uomo, occupando il grado centrale, gioca un ruolo importantissimo quale centro universale che ricollega tutto. Ed a proprio questa positione privilegiata dell' uomo in TP ad inflluire decisivamente la teoria ficiniana. Possiamo trovare la teoria degna d'attenzione dell'ars, appunto derivante dal privilegio dell' uomo, in TP XIII, 3 In questo capitolo e da notare la lode appassionata all'uomo come possessore dell'ays. L'uomo e il dio terreno, che esercita liberamente la propria ars, arrivando a sottomettere tutto a se stesso. La conseguenza di tutto questo e che il mondo diventa piu bello. La lode ficiniana e piu audace di quelle tradizionali rivolte all'ars. E visibile l'influenza sopra tutto dell'Ermetismo e di Giannozzo Manetti. Il secondo aspetto degno d'attenzione consiste nello stretto reciproco legame tra 'sapere' e 'fare':solo chi possiede la stessa ars-chi cioe puo produrre la stessa opera-puo comprendere quest'ultima. Viceversa, capire qualcosa significa poterlofare. Questo pensiero viene interpretato, e la sua originalita valutata, nel contesto della lunga tradizione del pensiero occidentale riguardo il rapprto tra 'sapere' e 'fare'. TPXIII, 3 e una clavis magna per la valutazione dell' originalita della teoria ficiniana dell'ars.

The purpose of this article is to examine the internal migration of a person burnt out by an urban air raid. With the expansion of air raids on Japan's urban centers during the war, a large number of civilians were burnt out of their homes. Therefore, the government pushed forward a plan to have such people emigrate to farm villages. However, such people have so far not been studied in historical research. We carried out an interview investigation in a farm village in Hokkaido to which such people migrated. Therefore, in this report, we want to consider the local emigration of a person burnt out by an urban air raid based on interview data.

[要約]平安時代後期から鎌倉時代の仏像の造像法研究は,木造仏においては修復事業などによりその成果が蓄積されてきた一方で,鋳造仏(金銅仏/鉄仏)については未だに途上であると言える。平安時代後期から鎌倉時代の鋳造仏の原型および鋳造技法に関しては,現在では木造原型(木型)による割込め型(合わせ鋳型)法が定説となっている。本研究チームは現在,千葉県館山市の那古寺銅造千手観音菩薩立像の科学調査等を準備しており,その過程で類型の多臂仏の調査を行った。本稿は千葉県・長柄町銅造准胝観音菩薩立像,滋賀県・園城寺銅造千手観音菩薩立像,兵庫県・常勝寺銅造十一面千手観音菩薩立像の3軀の調査報告とし,特に腕部の形状や構造に着目して原型および鋳造法について若干の推論を試みた。報告をまとめる過程で,蝋型鋳造法や木造原型焼失鋳造法等,またはその混合技法の可能性について言及することとなった。
