The present paper describes the application of an improved impression transfer vector method (Sakurai et al., 2007) to transform the three basic dimensions (Evaluation, Activity, and Potency) of higher-order impression. First, a set of shapes and surface textures of faces was represented by multi-dimensional vectors. Second, the variation among faces was coded in reduced parameters derived by applying principal component analysis. Third, a facial attribute along a given impression dimension was analyzed to select discriminative parameters from among principal components with higher sensitivity to impressions, and obtain an impression transfer vector. Finally, the parametric coordinates were changed by adding or subtracting the impression transfer vector and the image was manipulated so that its facial appearance clearly exhibits the transformed impression. A psychological rating experiment confirmed that the impression transfer vector modulated three dimensions of higher-order impression. We discussed the versatility of the impression transfer vector method.

We developed a facial image generating technique that can manipulate facial impressions. The present study applied this impression transferring method to higher-order impressions such as "elegance" or "attractiveness" and confirmed the psychological validity of this method using the semantic differential method. Subsequently, we applied this method to two types of cognitive experiments. First, we examined the contributions of texture and shape on the facial impressions by using those face images for which the impressions have already been quantitatively manipulated based on this method. Second, we used such stimuli to examine the effect of facial impressions and attractiveness on the "mere exposure effect." Thus, we concluded that the impression transfer vector method is an effective tool to quantitatively manipulate the facial impressions in various cognitive studies.

As the inaccuracy which was made in implant impression prevented passive fit, it needed to solder the sectioned framework at several locations to correct the inaccuracy. Many clinicians have suggested impression techniques which could make passive fit between implant and superstructure. The purpose of this research was to measure and compare the accuracy of three methods of taking impression with the strain amplifier. The experimental groups were classified as follows : Group I : splinted the two parts with $Futar^{(R)}D$ Occlusion. Group II : splinted the two parts with $DuraLay^{(R)}$. Group III ; didn't splint the two parts. The results were as follows ; 1. The values of strain in the vertical and horizontal surfaces were increased in the order of group I, group II and group III. 2. Group 1 showed higher accuracy of the duplicated casts in the vortical and horizontal sur faces than group II and group III (p<0.05). 3. There were no significant differences in the accuracy of the duplicated casts between group II and group III. From the above results, it is considered that the splinting method of impression copings could make an influence on the accuracy of the master casts. To improve the accuracy of the master casts, splinting the squared impression copings with the additional silicone occlusion materials is recommendable.

In order to analyze possible effects of senior hospital selection factors and service satisfaction on senior hospital patients' revisit of senior hospital, this study surveyed guardians of total 204 patients hospitalized in major 4 senior hospitals in Busan. As a result, this study came to the following conclusions: First, it was found that guardians considered appropriateness of medical treatment cost as the biggest factor of choice, which was followed by kindness of doctor and hospital employees, locational accessibility (traffic convenience), and doctor's medical capacity. Second, the factor analysis about patients' satisfaction showed that the influential factors consisted of satisfaction at medical staffs, satisfaction at nursing and care, and satisfaction at facilities. Third, there was not significant difference in the overall impression of hospital and the intention of revisit depending upon sociological variables. Fourth, satisfaction at nursing and care and satisfaction at facilities had significant effects on better satisfaction at overall impression of hospital, and it was noted that the shorter admission period and the less complaint led to the higher intention of revisit. Therefore, it is necessary to improve satisfaction at medical staffs, nursing and care, and facilities rather than patients' own sociological characteristics.

Sexiness is the image of a person who attracts attention regardless of his/her age, and today's society has created a more positive impression by transforming the image into something others consider even more attractive. Consequently, we begin to take interest in makeup, - a means of portraying a good impression. Eyebrow makeup in particular, being at the center of the determining factor of a good facial image, can be thought of as the makeup that can most effectively transform one's image. The purpose of this study was to analyze the difference in perceived sexiness depending on the general perception of eyebrow makeup. This study produced an eyebrow stimulus that applied the average rate of change in an image transformation of different eyebrows in order to raise the objective credibility of the sensibility evaluation so it could determine the figure of influence that eyebrows had on facial impressions. The research results showed that the majority of female university students believed that eyebrows were an effective means of expression in changing facial images and attributed a higher mature and sexy image if the average ratio of change was higher. The study, could also identify that a sexy image was perceived when the average rate of change was between 0.39~0.44. In addition, when the gradient of the shape of the viewers' own eyebrows was low, it could be verified that they perceived an image to be sexy from seeing eyebrows with a relatively high gradient.
