This paper describes an interactive learning-aid system for analytical comprehension of music by highlighting orchestral score in colors, and classifies and evaluates the learning process on the system. An orchestral music is composed to integrate many instrumental parts, and musicians have to be proficient in reading the score analytically in order to understand its multifaceted structure. However, many people often face difficulty in comprehending its musical structure: Some intermediate performers can read and perform their own part, but cannot understand the role of each part in the assembled whole. In order to solve this problem, our conventional paper proposes an interactive supportive system called ScoreIlluminator that enables musicians (and non-musicians) to easily represent how he or she recognizes an orchestral music, e.g. the differentiation of melody parts from the others, and the similarity across instrumental parts. ScoreIlluminator clusters the parts from an orchestral score according to their roles in the whole, and displays the clusters on the score by assigning a color to each cluster. The users can manipulate the clustering parameters with the user interface of the system. The system employs two major design concepts. One is ``colored notation'' and the other is ``directability''. The ``colored notation'' visualizes the roles and the relations between parts, which are estimated by the system. The estimation is based on the similarity metric of four musical features: rhythmic activity, sonic richness, melodic activity and consonance activity. Using these metrics, clustering phase is conducted using an unsupervised learning algorithm (k-means algorithm). Our system provides the ``directability'' with an interactive interface in which subjects can freely manipulate parameter settings and see the change in score-highliting in real-time. In this process, users learn the role of parts and the relationship between parts and explore multifaceted interpretations of the music. To verify the effectiveness of the system, we conducted a user-experience experiment with four intermediate musicians. The musicians showed various kinds of progress in interpreting the score. With the episodes from the experiment, we discuss how the system encouraged subject's analytic skill in orchestral-score reading and music listening.

アルゴリズムに関する基礎からの解説の初回として,目標設定の重要性について解説を行う.アルゴリズムが達成するべき目標の設定が正しくない場合には,その目標のもとに考案したアルゴリズムの実行結果が望ましくない場合があることを,ケーキ分割問題を例として示す.ケーキ分割アルゴリズムの達成するべき目標として無羨望が考えられている.しかし無羨望だけでは真に公平な分割ができないことを例をあげて示す.真に公平な分割のためには,無羨望のほか,アルゴリズム内の役割に関する羨望もないことも目標に追加する必要があることを示す.目標が異なるとアルゴリズムも違ってくることを,2者の分割アルゴリズムで示す.

Though this aspect of history has been studied very little, it is important and useful for the better understanding of history from broader perspectives. To begin with, disease (implicitly including death) and healing may have been the primary concern of the majority of people. Thus, it may be important to know what diseases people suffered from, how diseases were perceived, and what kinds of healing methods were applied at specific historical times. These issues are relevant to many other aspects, such as living conditions, the natural environment, demographic structure, and so forth. On the other hand, change in the healing system may occur with the introduction of a new religion and the acceptance of new medicine (e. g., Islamic and Western medicines). In political and economic history, the health and the size of the population were decisive factors of economic force and state power. Economic development might improve health conditions through improved nutrition, but the increase of population density and the development of transportation provided favorable conditions for the spread of diseases. Keeping these perspectives in mind, we will first see what kinds of diseases were prevalent in Indonesia, particularly Java and Sumatra. In describing this, I will try to relate certain diseases to social and economic conditions of the time concerned. Next, I will describe healing practice. Finally I will examine the use of herbal medicines in Java in the 1870s and around the beginning of the twentieth century.

Republic of Kenya achieved independence from England in 1963. But it is well known that the process of her independence was not so easy. There were so many conflicts against British colonial rule in Kenya. Mau Mau revolt was the largest and most intensive uprising in Kenya independent movement. Several reasons of this uprising already have been said by writers, historians, politicians and Mau Mau survivers. But even now no fixed theory to interpret Mau Mau revolt is appeared. It is obvious that Mau Mau revolt was the fight for Kikuyu land and freedom of Kikuyu people by Kikuyu people. The problem is that Mau Mau revolt included the phase of independent movement of nationalist, or not. Because most people who took part in this uprising were almost Kikuyu people, above all young Kikuyu people who had no land to cultivate. In this respect Mau Mau revolt was regarded as civil war between "haves" and "have-nots" in Kikuyu land.<br>Kikuyu Central Association in 1920s and Kenya African Union in 1940s were leading organization of political movement in Kenya. These organizations were led by more or less "haves" who were educated in the school of the Christian Missionaries. They were not always against British colonial rule and their purpose was wealth and political power in colonial system. Their movements were improvement of life to accept European life style and European civilization. Mau Mau revolt was different from these movement. Because most of people who took part in Mau Mau uprising were young and had not education of Christian Missionaries. In this point Mau Mau revolt was anti-European Christian civilization movement to keep identity of African.<br>In the beginning of 1900s Christian Missionaries came to Kikuyu land. They established Christian Missionaries schools. In 1910s they want to suspend the custom of girl's circumcision in Kikuyu land. Some of the Christian Missionaries decided to compel Kikuyu people give up the custom of girl's circumcision in 1920s. But Kikuyu people repulsed these policies of Christian Missionaries. As a matter of course, anti-Christian Missionaries movement was increased in violence in Kikuyu land. Kikuyu people denied to educate their children in schools of Christian Missionaries. They established their own schools and churches, which were Kikuyu Independent School to educate their children and Kikuyu Karinga School to educate Kikuyu traditional religion apart from Christian Missionaries.<br>The conflict between Kikuyu and Christian Missionaries in Kikuyu land had given influence on the independent political movement, especially later Mau Mau movement. In fact there are several reasons of Mau Mau revolt under British rule, which is labour policy, land policy and so on. The conflict between Kikuyu and Christian Missionaries was also one of the most important impact on Kikuyu Nationalism Movement.

飛騨山脈の隆起については,鮮新世後期から更新世初頭(2.7~1.5Ma)にかけて,最初の極大期があったとする点では,多くの研究者の意見が一致している.しかし,その後の第四紀の期間にテクトニックな隆起があったかどうかでは,意見が分かれていた.山麓の堆積物から隆起時期を推定する方法では,山脈の隆起がテクトニックなのか,アイソスタティックなのか,判定困難なため,本研究では飛騨山脈,爺ヶ岳一帯に分布する鮮新世後期~前期更新世の火山岩類の構造を解析した.この結果,これらの火山岩類はコールドロンをなしており,東に70°前後傾動していることが判明した.南方の高瀬川流域や槍穂高連峰での資料を加味すると,前期更新世後半(1.3Ma~)以降,飛騨山脈東半部の広い範囲で,東西圧縮場のもとでの挫屈による傾動・隆起を生じていることが明らかとなり,飛騨山脈の2段階にわたるテクトニックな隆起運動が明らかとなった.
