This study has two purposes: The first is to compare gifted with non-gifted about learning styles and examine differences in the preference of learning styles between group characteristics depending on gender. The second is to examine differences between gifted and non-gifted about the preference of learning styles. The participants were 152 students from the middle schools in A City. 76 students of them belonged to the gifted group and the rest were non-gifted group. LSDI Learning Styles Diagnostic Inventory has been employed as measurement tools. Besides descriptive statistics, ANOVA, ${\chi}^2$ analysis were used to measure items. The results from data analysis are as follows. First, there was difference in learning styles between gifted and non-gifted. Second, there was not difference in the preference of learning styles between groups depending on the gender. Finally, this study discussed the results and their implication, the direction of future research in understanding and interpreting of learning styles for their practical usages.

Line scan diffusion weighted imaging (LSDI) pulse sequence for 0.32 T magnetic resonance imaging (MRI) system was developed. In the LSDI pulse sequence, the imaging volume is formed by the intersection of the two perpendicular planes selected by the two slice-selective $\pi$/2-pulse and $\pi$-pulse and two diffusion sensitizing gradients placed on the both side of the refocusing $\pi$-pulse and the standard frequency encoding readout was followed. Since the maximum gradient amplitude for the MR system was 15 mT/m the maximum b value was $301.50s/mm^2$. Using the developed LSDI pulse sequence, the diffusion weighted images for the aqueous NaCl solution phantom and triacylglycerol solution phantom calculated from the line scan diffusion weighted images gives the same results within the standard error range (mean diffusivities = $963.90{\pm}79.83({\times}10^{-6}mm^2/s)$ at 0.32 T, $956.77{\pm}4.12({\times}10^{-6}mm^2/s)$ at 1.5 T) and the LSDI images were insensitive to the magnetic susceptibility difference and chemical shift.
