In this study, we evaluated the effect of aroma by using the chaos analysis of acceleration plethysmogram. We tried to apply the trajectory parallel measure (TPM) and the recurrence plot method (RP) as a chaotic analysis and used the value of TPM ave. (average of TPM) and the value of RP-dw (the ratio of white to the whole figure expressed by RP) for analysis. The value of RP-dw tended to decrease by the inhalation of peppermint and sweet orange in persons who liked the smell. And the value of TPM ave. was significantly decreased by the inhalation of sweet orange in persons who disliked the smell. The results suggest that the inhalation of aroma make the circulatory homeostasis more stable in persons who like the smell. On the other hand, it is considered that an unpleasant smell has simplified the blood stream by making the functional stiffness of the vessel wall decrease. The detailed mechanism is not clear though it is thought that the chaos of acceleration plethysmogram is a useful index that can inspect the change in the homeostasis of the living body. It is required that the mechanism will be clarified by the detailed examination of the change in the chaos index in the future.

This study aimed to determine the factorial structure of mental toughness for water polo players and to make up a questionnaire to evaluate it. A survey composed of 102 items representing seventeen sub-domains was administered to 510 water polo players, and data from 412 players (age: 17.4±3.8 yr, year of experience: 3.8±2.8 yr) with valid responses were analyzed. We selected 99 items from 102 items in a previous study after examining the internal consistency and discrimination power of question items. Oblique rotation by maximum likelihood solution and promax rotation were applied to a correlation matrix consisting of 99 items, and 15 factors with large eigen values were interpreted. Considering practicability, reliability and validity, fifty-one items were reselected representing 3-6 items with high loading from each factor (sub-scale). Reliability (α-coefficient) and relationships between total scores of 99 items and 51 items reselected in each sub-scale were high. From the above, mental toughness scales for water polo players in this study were considered to be useful with high validity and reliability.

A non-school attendant and withdrawal junior high school girl, who was recommended to see the mental clinic doctor, was followed up with e-mail counseling using the cellular phone and medical therapy, until admission in the university hospital for work up of visual symptomatic abnormality. 　In her clinical course, the e-mail counseling was analyzed by means of face (special) characters psychologically, which was much contributed to improving her severe clinical states, such as suicide attempts in unstable moods and many psychosomatic symptoms in non-school attendance. 　These novel therapeutic means mainly with e-mail counseling using cellular phone, will have general or universal desirable effects for such withdrawal pupil or another withdrawal cases in lonely and hopeless. We would like to develop another and more effective approaches in the educational and medical point of view to save a lot of struggling children doing efforts to get out of the dark world of withdrawal and non-school attendance.
