囲碁における定石や将棋における定跡は,主にゲーム序盤で用いられる決まった手順の互角の応酬であり,長い時間をかけて研究・洗練された人智の結晶である.テトリスやぷよぷよなどの落下型パズルゲームの多くでも,展開を有利にするための定石形が存在し利用されている.これらのゲームを囲碁や将棋と比較すると,自分と相手双方に盤が存在し邪魔は間接的にしか行われない一方で,操作対象の与えられ方(俗にツモと呼ばれる)にランダム性があり,状況に応じて用いる定石や配置順を変えていかなければならない難しさがある.本論文では,関連性行列という形で状態と定石を表現する定石形配置法を提案し,これをぷよぷよにおける連鎖の構成に適用することでその有効性を示す. : In Go and Shogi, standard patterns and sequence of moves have been developed over the years by human players, mainly in the opening of the game. Such standard patterns, used by expert players to reach a winning position, also exist in tile-matching video games like Tetris and Puyo-Puyo. In tile-matching games, the interaction between the players is only indirect through separate boards, but the randomness of the tiles appearing in the game is a major difficulty, not found in Go or Shogi. In this paper, we propose a tile arrangement method for finding good moves in tile-matching games, through the use of a relevant matrix that represents the current situation and the knowledge of standard patterns. We show the effectiveness of the proposed method by applying it to the construction of chains in Puyo-Puyo. The resulting Puyo-Puyo AI player is significantly stronger.

In Japan, what sort of people attend classical music concerts? It has been said that the classical music is an orthodox current of culture from the West, which was set up alongside the establishment of the modern educational system in Japan. Recently, however, the number of classes of music and other arts related subjects has been reduced as a result of the new national curriculum. In addition, the development of the Internet has provided a dramatic increase in terms of alternative access points to music. These are resulting in a dramatic change of music culture. Under these conditions, is it probable to think that attitudes towards classical music concerts might be in a process of change? The purpose of this paper is to illustrate the current conditions in relation to classical music concerts attendance from a sociological perspective. Methodologically, the paper draws upon evidence garnered from a questionnaire survey conducted at classical music concerts in Tokyo, Niigata and Kagoshima, between April and August 2002. To date, there have been few studies to investigate the sociological profile and associated behaviour related to classical music concert attendees, except the index of a stratum research. In this research, I will make use of sociological description of attendance, exploring the issue of regional difference. Subsequently I will analyze attendee's first experiences vis-a-vis the concert. Finally I will specify the features of attendance in relation to those classified as "Jouren" i. e. regular goers and those labeled "Ichigen" i. e first-timers. I will analyse the differences between them in light of a number of sociological indicators and their musical experiences during their formal education. As a kind of pilot study, I will propose a research framework that could provide a signpost for future research exploration.

We observed clear fractoluminescence in crystalline quartzite, quartz crystal and fused silica at uniaxial compressional loading tests by commercial digital cameras. These fractoluminescence are composed of blue and red colors. In particular, a blue color does not appear in fractures of fused silica but appear in crystalline quartzite and quartz crystal, which implies that the piezoelectric charge and discharge play a key role in the blue-color fractoluminescence via excitation of N2 molecules.
