magnetic sensorless sensing experiments of the plasma horizontal positionhave been carried out in the superconducting tokamak HT-7. The horizontal position is calculatedfrom the vertical field coil current and voltage without using signals of magnetic probes placednearby a plasma. The calculations are focused on the ripple frequency component of the power *** is no drift problem with the time integration of magnetic probe signals. The error of thederived plasma position is lower than 2% of the plasma minor radius.

Two-dimensional structure of density fluctuations is examined during the current jump phase, indicating a change from the open magnetic fields to the closed ones. During the smooth current ramp-up phase the two-dimensional contour of the LiI intensity shows vertically alignment, consistent with the magnetic surfaces. At the inflection point in Ip ramp-up the LiI intensity contour becomes flat in the observation regime and then suddenly a steep gradient and higher intensity regime are formed in the vertical direction. This higher intensity corresponds to a burst of LiI waveform. According to these changes in the contour, it is found that, within ~1 ms around the burst of LiI, a low frequency coherent wave with a long wavelength rapidly grows. The relations with other signals （magnetic flux and microwave stray power） are discussed with respect to the topological change in the magnetic configuration and mode conversion of the incident electromagnetic waves.

For the aim of synthesis of the carbon-iodine compound, the preparation of iodin e-included carbon using RF plasma CVD was studied. Iodine-included carbon was sy nthesized on Si substrate using ICP type RF plasma CVD apparatus. C2H5OH and I2 dissolved C2H5OH was used as reactant gases. As a result, surface morphologies o f Iodine included carbon films showed flat surfaces for each samples. On the str ucture of films estimated by Raman spectroscopy, amorphous carbon was recognized . And I2 peaks were observed in XPS spectra. As a result of friction test, frict ion coefficient of the sample growth with C2H5OH showed about 0.45. On the other hand, that of the sample with I2-C2H5OH showed about 0.3 and decrease of fricti on coefficient was recognized. Iodine inclusion for carbon materials can be achi eved by RF plasma CVD using an I2-C2H5OH reactant. The coefficient of iodine-inc luded carbon showed lower than of without iodine

The clinical evidence regarding the utility of magnifying endoscopy with narrow band imaging or endocytoscopy has also been evolving in regard to the diagnosis of IBD-associated neoplasia. These advanced endoscopic techniques are promising for multiple reasons;not only for making an accurate diagnosis of neoplasia, but also in determining if endoscopic resection is appropriate for such lesions in patients with IBD. In this review, we discuss the diagnostic accuracy and limitations of magnifying endoscopy in assessing IBD-associated neoplasia and examine the feasibility and outcomes of endoscopic resection for these lesions.

Density modulation experiments are successfully conducted on HT-7 ohmic discharge to investigate particle transport coefficients: diffusion coefficients D and convection velocity V. The particle transport is studied at low (1.5 x 10(19) m(-3)) and high (3 X 10(19) m(-3)) density regimes. The clear differences are observed that D is 0.42m(2)/s and 0.17m(2)/s, V is 4.7 m/s (outward) and 1.6 m/s (inward) for low and high density plasmas respectively, where spatially constant D and V(r) = (r/a)V-0 were assumed for the analysis.
