The purpose of this study is to clarify the skill-acquisition process for controlling speech timing used by professional actors while rehearsing a play. We conducted recurrence quantification analysis (RQA) (Riley et al. 1999) of the captured 94 video-recorded trials for one scene as time series of data consisting of marks of turn-taking. RQA revealed a tendency for the learning process of utterance timing to become more irregular (lower %DET) but, at the same time, more coherent (lower ENTROPY).

[English] Analysis era begun from the middle of the 19th century to the end of the 20th century brought us enormous progress understanding humanities, both in the scientific and literature worlds. Previous methods of Humanities education of methods can be divided into two types. The first is the method of knowledge transfer, and the second is the one with only practice. By either type of education method we cannot know own possibility and mechanism of self-learning and self-recognition, which may be characteristic of human beings. This study shows new type of education system to "know thyself (gnothi seauton), which was introduced to 3000 first-year students of the University of Tokyo from the academic year of 2006. The program, which consists of five essential components to the understanding of our own body and existence, is as follows; we should know 1) the gaps of expectation and reality, 2) human standing and walking system, 3) running intensity to keep global homeostasis, 4) cell unity as an autonomous life system, and 5) resuscitation principle. In particular we focus on and discuss the importance of two new fields of recently developed life and brain sciences that had not been academically recognized in the physical education learning. Only human beings can learn and realize ourselves through scientific visualization of "own action" and representation of their own activities with words. This method is based on recent life and brain scientific knowledge of "activity (use-, output-)-dependent gene expression system", epigenetic mechanism, cell theory, and protein homeostasis. This new management of oneself through action with scientific visualization of our body-mind system can be regarded as "human sustainability" and constitute one part of the area of "Alliance for Global Sustainability".

Several studies have indicated that thinking meta-cognitively about their own body is important for athletes to improve their performance. For a coach, constructing an environment for encouraging an athlete's thinking is one of the important tasks to improve the athlete's performance. No previous studies, however, discussed how to construct its environment. The purpose of this study is to discuss how to explore a learning environment, based on both a case study of coaching by trials and errors and a trial of development of a software tool for visualizing an athlete's form.

It is described about important role of flexibility of joints when power is generated for pitching or hitting showing mechanism how power is generated. How you can throw hard or how you can hit hard is all depends on how much flexible your hip joints are. It is also proposed a method to keep/ make the joints flexible and its potential possibilities with sports and health.

Receiving advice from an instructor often accelerates the process of mastering a skilled motion, and this implies that a piece of advice functions as a trigger that introduces a structural change into how the learner performs the motion. Taking a basic motion of wok handling as an example, this research observes several actual processes of learning it with advice, and characterizes the processes based on the sequence of advice and how the motion performance changes along it. As a result, it is found that the process differs among learners and that the instructor determines the set of advice to give based not only on the observable characteristics of the current motion performance but also on the history of the interaction with the learner.

In skill science framework, We have studied for supporting of performer - mainly cello player - with employing logical computation systems. In one hand, we suggested to derive hypotheses rep- resenting possible ways to given certain performance tasks using an Abductive Logic Programming (ALP) system. On the other hand, we suggested method called rule abduction, which find possible rules explaining observed 'knacks' as reasonable performing method. There remain many things those must be solved. For example, we should show some directions to select better hypotheses from derived by ALP or rule abduction. In this article, we deal with further problems. When novel rules are abduced by rule abduction, some of them would have undefined nodes those should be given some adequate meaning. We build 2 databases for cello playing domain which can pro- vide information for aiding decision of meaning of such nodes by the performer. Using the same databases, we try selecting hypotheses derived by our existing system.
