Body ownership illusion (BOI), which means 'the illusion that a non-bodily object feels like my body', has been actively studied since the Rubber-hand Illusion showed that a person can feel a rubber hand like one's own hand. It has been proven that BOI can be elicited for virtual bodies in virtual reality. Although many studies have been examined the effect of visuomotor (VM) and visuotactile (VT) stimuli, which are mainly used for the elicitation of BOI, there were very limited studies that delivered both stimuli to the whole body at the same time. In this paper, we investigated how each stimulus affects BOI when delivering VM and VT stimulisimultaneously to the virtual avatar, and examined user experience that appears as presence, emotion, and virtual motion sickness. The results showed that BOI was high when VM is synchronous, but there was no significant difference according to VT levels. In the case of presence, it was confirmed that VT affects only when VM is synchronous, and in the case of emotion, both VM and VT affect valence, and in the case of virtual motion sickness, a statistical difference is not found.These results suggest that overall synchrony of VM is important factor in BOI with virtual avatars, but that the matching VT affects subjective experience such as presence when VM is synchronous.

The purpose of this study is to survey differences of visual effects for location the york line. According to three types of body shapes(average, small & thin small & fat)for location of the york line We investigated the visual effects and optical illusion by slider and the results of data which analized by anova and duncan's multiple rannge are as follows. 1. In the A.V (average) body shapes design D1 was showed D1 was showed to be most remarkable in terms of optical illusion and design D2 was showed to be prefer in terms of visual sight. 2. In the S.T(small& thin) body shapes design D1 was showed to be most remarkable in terms of optical illusion but from the side view of looking thinness design D4 was showed to be nogative and from preference of visual sight design D4 was showed to be most negative. 3. In the S.F(small& fot) body shapes design D1 was showed to be most remarkable in terms of optical illusion and design D3 gained the bettle of superiority from the side view of looking tallness and design D3 was showed to be most negative in terms of the preference of visual sight.

The purpose of this study was to define the moaning and features of humor in modern fashion. by examining how it's being grafted into fashion, based on artistic expression including collage, assemblage, photo montage, graffiti, transformation, distortion, exaggeration and optical illusion. Beside. humor of fashion is to examine not only laugh and fun but also formative expression and creativity. Furthermore, it is to enlarge the range of conception for future fashion. The findings of this study could be described as below: The features of humorous fashion by collage and assemblage boiled down to unexpectedness, disharmony and creativity. The photo montage was marked by popularity, reproduction and recreativity, and graffiti was characterized by attention, simpleness, and amusement. And there were unexpectedness, creativity and strangeness in transformation, distortion, magnification and optical illusion. The meaning of humorous fashion that carries such features could eventually be summarized into the followings : First, the fashion, from which collage, assemblage, photo montage. graffiti, transformation, distortion, magnification and optical illusion were detected. could be sorted out into several categories that used different things : introduction of objects of different nature, dramatic impression and wit based on photo montage technique, introduction of comic components and infant image, and destruction of aesthetic principles. Second, the substance of humor in art could be applied to fashion design as well as visual art. Humor is a property related to accidental, unexpected incident, behavior, situation or idea, and it puts laugh, disharmony or awkwardness in fashion. Third, spicing fashion with humor could serve to draw people's attention, break down the barrier among people exposed to dry sentiment, and connect the public with art.

In this study an experiment was made using the function of computer simulation os to whether the phenomenon of optical illusion takes place also in clothing on the human body three-dimensional space through the case study of the Gestalt illusion of planar con-traction and expension by amodal completion in perceptual organization. One woman of latter 30s was selected as the experimental subject. She was made to wear the experimental clothing and then the frontal picture was projected of in the experimental clothing which was scanned into the com-puter. For the sake of the contractive experiment 5 stages were divided by 5-15cm the thick-nes of the black vertical line in the center of the upper garmet as the variable and for the sake of the expansive experiment the skirt length was set as the variable. It length measured 50-90cm which was divided by 10cm into 5 stages and simulated using the CAD. The basic design and the experimental de-sign were made one pair and the pictures totalled 20 pictures such as ten pictures save the human body for the estimation of the up-per garmet alone and ten pictures for the ob-servation of the effect on the human body. The extimating panel consisting of 20 panellers estimated contraction/expansion in the estimation of the upper garmet and the tall effect/the slim effect in the estimation of optical illusion as the estimating factors on the 9-point scale. All the date from experiment were analyzed by ANOVA(analysis of variance) and DUNCAN'S multiple range. As a result the experimental designs all showed a significant optical illusion in comparision with the basic design.

The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

The purpose of this study is to determine affects of hair colors on physical shapes and images through field survey and experimental research. For the purpose, this researcher surveyed 230 female college students residing in Busan about their dyed hair colors, and selected the subjects for the study. Then the researcher an experimental research on the subjects by suing test stimuli. Results of the study can be described as follows: Experiment of the Optical Illusion of Physical Shapes. For all items measured for the experiment, except four ones, if was found that hair colors provided significant efforts of optical illusion factor analysis, included horizontality, outlines of the body and face, a horizontal line of the shoulder, the length, verticality and a horizontal line of the face. According to hair colors, black made the body look slimmer and the face look apparent. White made the body height look low, the outline of the face look clear and the neck or shoulder look fleshed. Female college students whose hair color was orange looked unclear in the body silhouette, bright in the face and broad in the hip and shoulder. Other students whose hair color was red, attracting the line of vision upward most strongly, looked fleshed in the upper body and broad in the face. Finally, blue made the face look dark.

The main purpose is to study lines on different body types and to disguise any imperfections by using diverse princess lines. We separated festers body shapes into specific body types, A, H by applying both the direct and the indirect measurements. Following are the results of the study: 1. nose are the resulting illusion effects when the shoulder width of the princess line was fixed. In case of the armhole princess line, the illusion that the waist intervals were narrow or wide in A-line silhouette. In case the shoulder princess line, when the waist interval was narrow, it appeared to show narrow shoulder in A-line silhouette. While the wide waist interval shows the wide shoulder width in H-line silhouette. It regards body type H in the same light as H-line silhouette when the waist interval is narrow, it appeared to show narrow shoulder width in A-line silhouette. When the waist interval was wide, it appeared to give the narrow shoulder width. 2. When the princess lines waist width was fixed in order to study illusion effects of waist widths. Generally, for body type A, Whether the waist interval princess line is narrow or wide, the princess line is located comparatively wide, in A-line silhouette appeared to show relatively slender waist. For body type H, whether the waist interval is narrow or wide, the princess line us situated comparatively narrow interval, H-line silhouette appeared to show sum waist but the differences are not significant 3. The illusion of the hip were studied by fixating the width of the skirt and varying the locations of princess line and waist widths. For the location of both armhole and shoulder princess line in H and A-line silhouette, the narrow shoulder width and the waist appeared to show narrow hips. mile they are wide appeared to show wide hips. 4. With both waist and skirt width fuel, all two body types showed taller and slender postures when the princess line originated from the shoulder compare to the armhole.

We examine whether the observed negative relations between stock returns and inflation and between housing returns and inflation can be explained by the inflation illusion hypothesis. We identify the mispricing component in asset prices (i.e., stock prices and housing prices) based on present value models, linear and loglinear models, and we then investigate whether inflation can explain the mispricing component using the data from three countries (the U.S., the U.K., and Korea). When we take into account the potential asymmetric effect of positive and negative inflation on the mispricing components in asset prices, which is an important implication of the inflation illusion hypothesis, we find little evidence for the inflation illusion hypothesis in that both positive and negative inflation rates do not have a negative effect on the mispricing components. Instead, we find that behavioral factors such as consumer sentiments contribute to the mispricing of asset prices.
