In MR functional imaging, it is shown that the signal change during photic activation is composed of two terms, i.e. the inflow effect and the susceptibility effect. Relatively the inflow effect affects the data obtained by CGE on the condition of short $T_E$(15ms) and large $\alpha$(90degree). The susceptibility effect, however, mainly contributes to the data on the condition of large $T_E$(35ms) and small $\alpha$(30degree). In this apper, we will discriminate the susceptibility effect for the intermingled data affected both flow effect and susceptibility effect. Finally susceptibility only functional imaging is proposed by using TRFGE.

The study of the awareness on DM, the degree of satisfaction, and intention of word-of-mouth has found that when the confidence factor is stressed, intention of word-of-mouth is seen to rise, and when the perception factor is placed emphasis on, intention of word-of-mouth is also seen to be on the rise. The 790 questionnaires collected were analyzed by frequency, factor analysis, confidence degree, and regression analysis. This means that the higher the degree of satisfaction by means of the recognition, attention, trust of DM advertisement, the relationship reenforcement of DM advertisement and transmission of information is, the higher intention of word-of-mouth is. Beauty art business is characteristic of visits being connected with sales. The awareness has an effect on the degree satisfaction, and it affects intention of word-of-mouth.

This research investigates the effect of fashion leadership on Word of Mouth (WOM) communications on the Internet. This research categorizes consumers into groups by fashion leadership and compares the groups regarding the WOM behavior (degrees of WOM acceptance and delivery as well as the motivations of WOM acceptance and delivery). The subjects of the study were 325 males and females. Major statistical methods used for the study were factor analysis, ANOVA, Scheff$\acute{e}$'s test, and chi-square test. The results categorized consumers into five groups by fashion leadership (dual leaders, fashion innovators, fashion opinion leaders, fashion followers, and fashion laggards). There were significant differences among fashion leadership groups over WOM behavior (acceptance and delivery) and monthly clothing expenditures. Fashion dual leaders had a higher degree of WOM acceptance with motivation of fashion information acquisition and compliance, and they had a higher degree of WOM delivery through motivation of economic compensation, pleasure, and advice. In addition, they had a higher expenditure for clothing products. Fashion innovators had a lower degree of compliance in WOM acceptance. Fashion opinion leaders had a higher degree of WOM delivery through motivation from advice. Fashion followers delivered WOM through motivation of economic compensation and advice. Fashion laggards had a lower degree of WOM acceptance and delivery.

Geotechnical materials such as silt, fine sand, or coarse granular soils may be unstable under undrained shearing or during rainfall infiltration starting an unsaturated state. Some researches are available describing the instability of coarse granular soils in drained or undrained conditions. However, there is a need to investigate the instability mechanism of unsaturated silty soil considering the effect of degree of compaction and net confining stress under partially and fully drained conditions. The specimens in the current study are compacted at 65%, 75%, & 85% degree of compaction, confined at pressures of 60, 80 & 120 kPa, and tested in partially and fully drained conditions. The tests have been performed in two steps. In Step-I, the specimens were sheared in constant water content conditions (a type of partially drained test) to the maximum shear stress. In Step-II, shearing was carried in constant suction conditions (a type of fully undrained test) by keeping shear stress constant. At the start of Step-II, PWP was increased in steps to decrease matric suction (which was then kept constant) and start water infiltration. The test results showed that soil instability is affected much by variation in the degree of compaction and confining stresses. It is also observed that loose and medium dense soils are vulnerable to pre-failure instability i.e., instability occurs before reaching the failure state, whereas, instability in dense soils instigates together with the failure i.e., failure line (FL) and instability line (IL) are found to be unique.

The purpose of this study is to identify the principal factor controlling transverse residual stress at the weldment for joining unit hull blocks. In order to do it, the comprehensive FE analyses were carried out to evaluate the effect of distance between fillet and butt weldments, in-plane and out-of-plane restraint degree on the amount and distribution of transverse residual stress in way of the weldments between unit hull blocks. In accordance with FEA results, principal factor controlling the amount of transverse residual stress at the weldments was identified as in-plane restraint degree of butt weldment for unit blocks. The effect of other variables on the transverse residual stress was very small relatively. Based on the results, it can be concluded that the proper distance between fillet weldment for stiffener and butt weldment for joining unit blocks should be determined in consideration of in-plane restraint intensity of butt weldments.

As a basic study for developing a forecasting/estimating system that predicts water quality changes when Deep Sea Water (DSW) drains to the ocean after using it, this study was carried out as follows: 1) numerical simulation of the present state at DSW developing region in the East sea using SWEM, 2) numerical prediction of water quality changes by effluent DSW, 3) analysis of influence degree 'With defined DEI (DSW effect index) at F station. On the whole, when DSW drained to the ocean, Chl-a, COD and water-temperature were decreased and DIN, DIP and DO were increased by effluent DSW, and Salinity was steady. According to analysis of influence degree, the influence degree of DIN was the highest and it was high in order of Chl-a, COD, Water-temperature, DO, DIP and Salinity. The influence degree classified by DSW effluent position was predicted that suiface outflow was lower than bottom outflow. Ad When DSW discharge increased 10 times, the influence degree increased about $5{\sim}14$ times.
