Learning and emotions are very important parts to implement intelligent robots. In this paper, we implement intelligent virtual character based on reinforcement learning which interacts with user and have internal emotion model. Virtual character acts autonomously in 3D virtual environment by internal state. And user can learn virtual character specific behaviors by repeated directions. Mouse gesture is used to perceive such directions based on artificial neural network. Emotion-Mood-Personality model is proposed to express emotions. And we examine the change of emotion and learning behaviors when virtual character interact with user.

Circadian rhythms in subjective alertness, mood, and performance can be classified as psychological rhythm, compared with physiological rhythm such as body temperature and hormonal change. While in normal condition entrained by 24hr zeitgeber, subjective alertness would reach its maximum value around midday, subjective alertness would parallel body temperature rhythm with its peak at evening in non-entrained, free-running state. With desynchronization technique, subjective alertness rhythm is thought to be controlled by both temperature and sleep-wake rhythm oscillator. Circadian performance rhythms depend on the kind of task tested. It shows parallelism with body temperature rhythm when subjects are tested with simple, repetitive task. But when tested with tasks requiring complex verbal reasoning or immediate memory, subjects would perform them best at early morning, with performance decreasing as time of day advances. The desynchronization technique shows that circadian performance rhythm of simple, repetitive task is dependent on temperature oscillator but circadian performance rhythm of complex verbal reasoning is influenced by both temperature and sleep-wake rhythm oscillator or another independent oscillator. It would be worthwhile to compare psychological rhythm with hormonal change such as cortisol and melatonin. And more simple and time-saving method than desynchronization technique may facilitate the study of the mechanism underlying psychological rhythm.

Objectives We aimed to examine whether mindfulness skills are mediating the improvements of depressive symptoms in patients with mood disorders who practiced Mindfulness-Based Cognitive Therapy (MBCT). Methods A total of 19 patients with mood disorder were included in this study. The participants were divided into two subgroups: a normal to mild depression group and a moderate depression group. The participants completed questionnaires to assess depressive symptoms, anxiety, quality of life, suicidal idea, and mindfulness skills which were measured by the Five Facets of Mindfulness Questionnaire (FFMQ) before and after MBCT course. Results The moderate depression group showed improvements through MBCT in depressive symptoms and suicidal idea, but not in anxiety and quality of life. The normal to mild depression group showed no significant change through MBCT. The improvement of depressive symptoms in the moderate depression group was predictable by improvements of the five facets of mindfulness, especially by 'observe' and 'non-react' components. Conclusions This study showed that currently depressive patients with moderate severity but not with normal to mild severity benefit from MBCT in reducing depressive symptoms and suicidal idea. The improvement of depressive symptoms was mediated by improved mindfulness skills through MBCT.

The purpose of this study was to quantitatively examine the physiological and psychological effects of a waterscape facility in an interior landscape space. Data were collected as participants under stress relaxed in either an interior space with greenery(Type G) or an interior space with a waterscape facility(Type W). The participants relaxing in the Type W space showed significantly decreased systolic and diastolic blood pressures, and an impression evaluation by the SD method indicated that their impressions were expressed in more positive terms, such as 'vigor', 'dynamism', 'pleasantness', and 'vitality'; when compared to participants relaxing in the Type G space. A POMS analysis showed waterscape elements influenced participants' psychological mood states by decreasing tension and fatigue, but increasing vitality. Introduction of waterscape facilities into interior landscape spaces could therefore provide stressed individuals with health benefits, including decreased blood pressure and positively changed psychological mood states.
