最も有名な公開鍵暗号としてRSA暗号とだ円曲線暗号があり,SSL/TLSによる暗号通信や電子政府でのディジタル署名などで広く普及している.一方で,これらの暗号は量子計算機による多項式時間の解読法が知られているため,量子計算機に耐性のある数学問題を利用したポスト量子暗号(Post-Quantum Cryptography)の研究が注目を集めている.実際,2015年8月にアメリカ国家安全性保障局NSAはポスト量子暗号への移行を表明し,2016年2月には米国標準技術研究所NISTがポスト量子暗号の標準化計画を発表している.本稿では,ポスト量子暗号の歴史と標準化計画の概要を紹介し,代表的なポスト量子暗号となる多変数多項式暗号と格子暗号の構成方法と安全性の評価方法を解説する.

We developed a system that makes viscous sensation to the human legs in mud like wet rice field. In the first half of this paper , we mentioned a structure and a system of the force display device to the legs and its motion. In the latter half part, we mentioned some results of the experiment to evaluate comparative with real mud rice field. As the experimental results , we confirmed that the result next to real thing and almost subjects could fell it as (environment of) mud rice field.

During World War II, it is known that a lot of Nogaku works were newly written in order to encourage the wartime spirit. Among them, Churei (1941) and Miikusabune (1943) have distinctive features in terms of their large-scale performances and social impact. Churei had more than 100 performances after its premiere, touring nationwide from northern Hokkaido to southern Kyushu. Significantly, in 1942 it was presented at Korakuen baseball stadium in front of over 30000 people. In addition, Churei and Miikusabune were widely spread by record, radio, and news documentaries. This seems to be an exceptional case in Nogaku which has historically had a closed form of performance.Why could Churei and Miikusabune become propaganda for the War? Originally Nogaku was supported by a small number of wealthy patrons, so there was no need to assume an unspecified number of spectators. But at the end of the Meiji era, the middle classes such as business people and intellectuals enjoyed as a hobby practicing utai (the chant of Nogaku). Moreover, in the Taisho era there was a “popularization controversy” concernig whether Nogaku should be liberated from specific classes. Furthermore, after the reconstruction from the Grand Kanto Earthquake (1923), the approach of theatre commercialism came to be recognized as necessary for survival.This paper discusses the “commercialization of Nogaku” that already had been in progress during the Wartime through the investigation of those two works.

'Lifeworld' is a social field in which people have everyday face-to-face communications and interactions, and in which what they say and do inevitably influences it. It is meaningfully autonomous from modern subsystem fields such as the state and capitalist economy in which actions are adjusted by controlling media such as administrative power and money. Lifeworld is 'the horizon within which communicative actions are "always already" moving (Habermas 1987: 119)'. It evades our cognitive grasp. It has a form of knowledge on its own, which comprises assumptions and skills that we make use of almost without awareness (Habermas 1987: 113-197; Nakaoka 1996). Habermas holds that in the late capitalism lifeworld is controlled or 'colonised' by modern system fields and may lose autonomy and liveliness. This article aims at elucidating how gossiping can inspire the embodied imagination shared by participants to prevent 'colonisation' of lifeworld by modern systems, by drawing on data concerning rabies, ninja and vaccination in Flores, Indonesia.

River improvement works in the Kanto Plain have long history of over 400 years. Rice-paddy development in the Kanto Plain was significantly delayed compared to that in other plains including the Osaka Plain and the Nobi Plain. This was because of the difficulty in constructing an irrigation and drainage network, and protecting rice paddies from inundation. Therefore, the Tokugawa government started river improvement works in the Kanto Plain just after Tokugawa settled in Edo in 1590, and the works continue now. The flow of the Tone River into Tokyo Bay was originally blocked by uplands, but was finally rerouted to Choshi, 90 km east to the original mouth. The Ara River was also rerouted to the south. The purpose of rerouting was not only to reduce the risk of flooding in Edo city, but also to develop a waterway network for rice paddies to expand in the central Plain. Moreover, rerouting and connecting the Tone River with the Edo River enhanced the inland waterway transportation network of the Kanto Plain. Accordingly, a number of riverside towns, or Kashi, grew as nodes of the network. Small sailing ships and flatboats were the major conveyors of products. During the Meiji era, which followed the Edo period, canals were constructed and steamboats were introduced to replace sailing ships, at a time when water transportation was peaking. The inland waterway soon began to be replaced by present-day economic transportation systems such as rail and road. The central Kanto Plain was featured consistently by a subsiding basin through the Quaternary. Although the entire Plain was uplifted, Tokyo Bay, at the center of the Kanto Plain, sank over 1000 m. In contrast, the outer margin of the plain was uplifted 50 to 1000 m. Choshi, at the mouth of the present Tone River, is in the uplifted area. In contrast, the lower reaches of the River are at the northern extent of the subsiding basin. This is the reason why back swamp lakes or an estuary such as Kasumiga-ura and the ancient Katori-no-umi were formed in the area. Such crustal movements in the Kanto Plain continued throughout the Quaternary. Hydration and dehydration of two plates lying beneath this region were the driving force. Hydration of mantle peridotite underneath the Kanto Plain due to dehydration of the underlying Philippine Sea Plate (PHS plate), subducting from south to north 30-60 km deep (2 cm/year), causes volumetric expansion particularly at the marginal zone of the overlying plate (North American (NA) Plate). Serpentinized peridotite, produced above the Pacific Plate (PAC plate), which subducts from east to west under the PHS and NA plates, expands like popcorn and results in uplifting of the Boso Peninsular (non-volcanic outer arc) . In contrast, the sinking of the Tokyo Bay area is explained by the overlapping of the fore arc basin towards the PHS and PAC plates. From the viewpoint of tectonics, the sinking belt including Tokyo Bay is in a physical field where a sedimentary basin formed under tensile stress in the NE-SW direction. Small mantle convection caused by serpentinization of the uppermost mantle beneath the fore arc is the key to understanding the tectonic setting of the Kanto Plain.

Since the birth of electroacoustic media our listening attitude has been changed fundamentally, because of the very character of those media : the acousmatic. P. Schaeffer has defined it to listen to the sounds of which sources are invisible or unknown, refering to Pythagorean ritual. The traditional listening attitude has assumed the real sounding substance behind the reproudced sounds. But nowdays, because of the development of music technology, we can mostly get sounds that have been created from scratch or modulated electronically as a whole. We listen to surface sounds, which are also real in another meaning. Today, even in the live performance of traditional classical music, people receives it in the same manner as through the acousmatic media. It means that the model of the musical experience becomes the acousmatic. It follows the loss of the physicality in the experience of sounds. Some effort in the electroacoustic and computer music are made to retrieve the physicality of sounds, investigating live performance or interactive systems. Or, it is pursued that certain contextualization of those sounds occurs while receiving those acousmatic sounds, by cover jackets, liner notes or discourse of record reviews. In either case, however, if we lose the experience of the real live sounds, we must be imprisoned in a kind of cultic world.
