Large size hydrogen neutral beam injectors （NBI） used a negative ion source （NNBI） as well as a proton source （PNBI） were developed for the large helical device （LHD）. The injected power from NNBI and PNBI have reached 16 MW and 6.8 MW, respectively, These injected powers have outstripped the nominal beam powers. A diagnostic system of beam-emitted hydrogen visible spectrum has been installed along the beam injection axis to estimate the energy fraction on PNBI. The full energy beam component is about half which is equivalent to 70% of injected beam power. The attenuation of high energy neutral beam is also observed on NNBI. The peak density distribution is effective to increase beam deposition power.

The aim of the present study was to investigate the relationship between stress response, gender, weight management, and physical exercise among Japanese university students. The participants were 411 university students （169 males, 242 females）. All participants completed the Stress Response Scale and the European Health and Behavior Survey. T-test results showed that scores of females were consistently higher than those of males （P 〈 0.05）. In the chi-square test, the proportion of females managing their weight （75.3%） was significantly higher than that of males （42.9%）. In multiple regression analysis, the group managing their weight showed a higher stress score, and the group doing physical exercise showed a lower stress score. These results show that weight management through physical exercise reduces mental stress, making it the most beneficial method of weight management for the mental and physical wellbeing of youths.

Studies on TGS （toe-grip strength） are currently proliferating as a result of the development of the dynamometer. The purpose of the present study was to investigate the reliability and validity of TGS as a physical function in preschool aged children. The participants were 153 preschoolers. Each participant was measured in terms of his or her TGS and completed a MAT （motor ability test）. The reliability of the measurements was investigated via Pearson＇s r and Cronbach＇s a through a test-retest method, as well as a Bland-Altman plot. The validity of the TGS value was investigated by measuring the correlation between TGS and each component of the MAT, the principal component analysis, and a two-way layout ANOVA with general linear model （gender and age）. All reliability coefficients were more than 0.70. Though all components of the MAT relating to TGS were found to be significant （P 〈 0.05）, these correlations were weak. However, TGS was found to be a physical function that relating to the lower limbs and develops with aging. Therefore, TGS was found to be a highly reliable measure of physical function performance in preschoolers.

It is predicted that the distribution on score of children＇s motor performance show abnormal curve, because their physical fitness shows decline and gap between good and poor. The aim of present study is to type pattern of distribution curve on physique and motor performance （PMP） in preschoolers, and to investigate gender difference, and change in season and age on distribution of PMP. Seven hundred and seven preschoolers participate in measurement on 21 items of PMP. And mix-longitudinal data which made from 6 terms （2 seasons of spring and autumn for 3 years） is completed. The histograms of 10 sections are trained for each gender, term, and test item based on range of data including mean ± 3 standard deviation. By cluster analysis and multi-correspondence analysis, ＂physique ＆ jumping＂ show closely normal curve, but ＂manipulation （MP）＂ is skewed to poor and ＂running ＆ prompt （RP）＂ is skewed to good. By Hotelling＇s T2-test and Mahalanobis＇ Distance, gender difference is shown that boys＇ RP is skewed to good, and their ＂throwing＂ and ＂weight ＆ flexibility （WF）＂ are skewed to poor. About season, WF is skewed to poor and RP is skewed to good, in spring. In annual change about pattern of distribution, skewing poor in MP and good in ＂running straight ＆ prompt＂ are changed to normal curve with aging.

A transport simulation has been done by using a i.5D time dependent transportcode to reproduce a formation of the ITB on electron temperature Profile during the long pu1seLHCD in JT-60U tokamak. The transport coefficients were assumed to reduce with a reversedmagnetic shear and the LH driven current profile was evaluated by fitting dynamic change inthe measured current profile. The gradual increase in the central electron temperature could beexplained by the change in the current profile during LHCD in the present simulation model. Theestimated LH-driven current profile by the transport code analysis shows a finite current densityat the plasma center. Analysis of transport simulation suggests some mechanisms for broadeningthe LH-driven current profile at the central region of the plasma.

1 Introduction At the spinal level, the dopaminergic, the α1adrenergic and the neurokinin receptors play definite roles in the micturition control. From the anatomical point of view, the spinal center of micturition is located close to the center of erectile function. Recently, apomorphine is used for the treatment of erectile dysfunction and its mechanism of action is considered to be mainly through the central nervous system. 2 Dopaminergic receptors and bladder function at the spinal level
