Abstract—This paper examines an optimum type of dialogue between teacher and a humanoid robot, particularly appropriate for the situation where the students listen to the teacher-robot dialogue in a classroom. We extracted the types of dialogues from the comedy talks, the plot of movies, and the science shows. The generalized structure of the dialogue is a series of activation, main idea, and feedback. To interact with students and to retrieve information from a web learning system, the activation and feedback are assigned to the teacher, while the robot took part in the main idea.  In the activation phase, the teacher provides a topic keyword to trigger the robot to make a URL query request on the topic. Topic Maps ontology of the web learning system enables the robot to talk on the topic in the main idea phase. Finally, the teacher makes the point clear in the feedback phase to set up interest and fun of the topic. The teacher interacts with the students in the activation or feedback phase.

Abstract—The author proposes a method to construct a stochastic differential equation (SDE) describing a non-Gaussian process in a stationary state. A static potential function that represents the temporal average can be obtained from the time series after preprocessing and be expressed in a dual space. SDEs have been proposed as mathematical models of body sway. However, directional perturbation of the galvanic vestibular stimulation promotes periodic changes in the potential function in a component. Therefore, we discuss a new method to construct a SDE without preprocessing, which is different for each component.

Abstract—Educational effect of STEM education especially a design competition for students in the field of nanotechnology is discussed in this paper. Molecular design competition BIOMOD is founded in 2011, now becomes an influential competition attracting many young generations to DNA nanotechnology. The background of the competition, its structure and an example of awarded project is introduced to demonstrate educational effects of the competition.

Abstract—Determination of the longitude is the unification of space and time. The course note is presented to understand the points in the longitude problem within the framework of 16-8 Centuries. Establishing local time is difficult, because there are leads and lags of the Sun’s culminations, known as ‘Equation of Time.’ The Sun’s motion in the celestial sphere is nonlinear because of geometrical and gravitational reasons. The novel algorithm is proposed to get the rigorous Equation of Time.  Three brilliant astronomers had stayed in St Helena. They themselves determined the longitude of the island by different methods. By use of their and other observations of astronomical events the new calculations are available. These are the sources of the exercises. Edmond Halley states the island in 7 degrees west of London. There are three observations of the Transit of Mercury on 7th November 1677: 5o53’21”W by Towneley data and 6o26’44”W by Avignon data. Nevil Maskelyne determined the longitude to be 5o49’W based on eclipses of Jupiter’s satellites in 1761. Using observations of the total lunar eclipse on 18th May 1761 at the island, Cape and Stockholm, one obtains 5o49’05”W. Manuel John Johnson reached the conclusion of 5o43’39”W by the lunar distance method (1830-33). Using observations of the total solar eclipse on 27th July 1832 at the island, one obtains 5o27’51”W. Those results may reveal errors of sorts, or the island may be drifting towards Africa.

Abstract—Much of early research on chaos from the viewpoint of physics was performed using spatially confined convective systems. The technique and criterion to determine whether a nonperiodic oscillation appearing in such convective system is chaos have been established. In spatially extended convective systems, on the other hand, spatiotemporal chaos occurs. In contrast to chaos, there is no unified definition for spatiotemporal chaos due to the diversity. A unified viewpoint for three kinds of spatiotemporal chaos in electroconvection of nematic liquid crystals is presented through information reduction for the spatial patterns.

Abstract—Evaluation is required to hand down expertise and skills. In this study, we discuss the automatic algorithm to help diagnosing and evaluating severity of a sleep disorder.  The rapid-eye-movement (REM) sleep behavior disorder (RBD) is well-known REM sleep without atonia involves increased muscle activity, as seen on electromyography channels during polysomnography. Although close follow-up of patients’ recovery process is required and several visual inspection methods have been developed for the PSG reading, clear diagnostic criteria for assessing RBD severity have not been established because of the complicated nature of the procedure. In this study, we constructed automated algorithms based on the AASM scoring manual, Montplaisir et al., and SINBAR. The results evaluated by the automated algorithms were compared to the diagnosis by the visual inspection method. Nonlinear classification analysis was also employed to examine whether the healthy subjects group was significantly different from the group of suspected RBD patients. The misclassification rate of the SNBAR algorithm was found to be lower than that of the other algorithms.
