Subsurface physical properties can be obtained and imaged by seismic exploration, and various algorithms have been developed for this purpose. In this regard, root mean square error (RMSE) has been widely used to quantitatively evaluate the accuracy of the developed algorithms. Although RMSE has the advantage of being numerically simple, it has limitations in assessing structural similarity. To supplement this, full-reference image quality assessment (FR-IQA) techniques, which reflect the human visual system, are being investigated. Therefore, we selected six FR-IQA techniques that could evaluate the obtained physical properties. In this paper, we used the full-waveform inversion, because the algorithm can provide the physical properties. The inversion results were applied to the six selected FR-IQA techniques using three benchmark models. Using salt models, it was confirmed that the inversion results were not satisfactory in some aspects, but the value of RMSE decreased. On the other hand, some FR-IQA techniques could definitely improve the evaluation.

This study is about the effect of experience activities of fam tours in Korea on brand assets and revisit intention to revisit. In other words, the fam tour experience(feel, relate, sense, think, act) in research hypothesis 1 will have a positive (+) influence on brand assets(recognition, image, perceived quality, loyalty, and exclusive assets). In addition, it was set that the brand asset in Hypothesis 2 would have a positive (+) significant effect on the revisit intention. To verify this, 362 questionnaires were collected from MZ households in the metropolitan area and statistical analysis was conducted. The analysis results are as follows. First, in Hypothesis 1-1, the fam tour experience (feel, relate, act) has a positive (+) effect on awareness, In Hypothesis 1-2, the fam tour experience (relate, sense, think) has the effect of positive (+) on the image, In Hypothesis 1-3, the fam tour experience (feel, relate, sense, think, act) is the influence of perceived quality, In Hypothesis 1-4, the fam tour experience(sense, act) has a positive effect on loyalty, In Hypothesis 1-5, the fam tour experience (feel, relate, sense, think) had a positive (+) effect on exclusive assets. The brand assets(awareness, image, quality, loyalty, and exclusive assets) of the rural fam tour in Hypothesis 2 were significant for revisit intention.

Façade design makes the customer to select and remember of commercial space. Therefore, if it can be identified characteristics of perception in image evaluation, it will be possible to easy visiting space and re-selection with motivation through identity and differentiation of commercial space. For this study, cafes among commercial facilities were selected for the appreciation of the differentiated design features attracting customer's eyes through space image evaluation by gender. The followings are the conclusions drawn from the study. First, when the features of mean and deviation of [Factor 1] were employed for the appreciation of the perceptual characteristics of both men and women, it was clearly found that customers regards the facade design as a coarse one even though they are confused about whether the facade design is the straightened-up one. Second, customers perceive facade design as the one which is bright but not unique through [Factor 2] while in the process of selecting adjectives to describe it men's perception as to "being vivid but interesting" was dispersed and women's as to "Being bright" was also dispersed, too but the women perceived it as "being opaque". Third, it was revealed that the perceptual characteristics of [Factor 3] were perceived as "warm but boorish" and "warm but crude" by men and women respectively. Fourth, most (80%) of the adjectives employed for vivid description of their perception by both genders were found to be consistent.

The purpose of this study is to provide the methods of harmony in color combination of environmental color for apartment in order to improve the image of the urban landscape. For this study, apartment in Iksan City was selected is a sample and twenty two apartments were analyzed. This framework of this study is A. Hard and L. Sivik's color combination model based on Natural Color System. This study examines various theories on environmental color perception and new approaches to color aesthetics, and tries to present perceptual properties that can be applied to environmental color design First, the principle of color harmony feeling in based on nuance and tone. Therefore, to control brightness and chromaticness with are related with nuance is important in color combination. Second, the aesthetic experience in color preception can be defined as a combined effect of similarities and differences of color attributes. Third, color harmony theory is one of the areas that can be benefit a great deal from and interdisciplinary approach, add empirical study such as this can be used as a basis for environmental color design and evaluation.

In addition, an intense competition depending on the diversity of consumer demands women's clothing brands show changes in market organization such as diversification of the circulation market and general market depression in this rapidly changing fashion environment. Companies tend to use fashion VMD (a marketing-strategic approach) as a differentiation method to create a fashion brand shop image as brand differentiation becomes difficult due to generalization of techniques. This study analyzes forms and types of VMD recognized by consumers within this marketing communication environment and Q methodology was adapted to analyze the subjective internal order of individuals. First, a set of stimuli that presented the brand name and another without it were prepared (two sets in total) to examine the effects in the presentation of the brand name. Stimulants with the brand name were presented to the subjects by the same method after an experiment through stimuli without the brand name presented. As a result, VMD recognition factors were classified into 4 Q factors in cases of stimuli without brand names and 2 factors in cases of stimuli with brand names. This indicates that among brand functions, the role of simplifying information management and grasping the thoughts of consumers was applied. This study has a practical value of presenting VMD directions of each brand image based on the factors discovered.

For the user-centered interior space design, a designer needs to carefully focus on the details from which the user must keenly observe or concentrate on the space and how to deliberately check the image of the space. Following this view, for the user-centered interior space design this study analyzes the way which the space is represented from the perspective of the image assessment. The results obtained from this study are summarized as follows: First, this study analyzed the characteristic of space image change in the form of cross-comparison between one space and a rotated space. With analyzing of an eye fixation by showing the space, the space images of "concentration-dispersion" and "strengthening-weaken "have an important role in the analysis of the perception of space. it confirmed that the method of space perception was changed by rotated the space. Second, With changing quantities of image and extraction of deviation from adjective in survey, it quantitatively graps that respondents of feel in space perception by changing the space and "concentration" and 'dispersion" for process of space choice. The results of the research can provide important basis to judge the changing of space perception by visual perception. Third, through the analysis of image change rate and deviation rate, the characteristics of image change with space change can be analyzed. The results derived from the study provide the evidence to support the image change by space rotating.

Today, the children's museum evolved from place of exhibition for seeing and feeling, to that of exhibition for searching and touching, or so-called the hands-on exhibition. This will allow for grabbing the interest from children and provide an opportunity for learning by an actual experience at this intellectual and benign environment. But in this modern society that constantly undergoes evolution even as we speak, it is not an easy task to bring our children to museums, because they are vastly exposed to various media. Moreover, if the children who visited museums carelessly bypass the specific areas intended for exhibition, the educational purpose of "enhanced learning effect with hands-on experience" is easily underachieved. According to children's visual stimuli, their behavioral charactoristics are appeared to freewill curiosity but they show shorter elapsed time(impermanence), intensity(stubbornness), frequent occurrence(frequentness) and changeable (translatability). So, We need Improvement of visual image affordance through the measurement of stay time. Firstly, five factors are extracted by factor analysis on twenty questions based on visual image factors; Color accessability and Satistaction(factor1), brightness and color harmony(factor2), feeling on harmonization of color and stay time(factor3), simplex & complex of space(factor4), feeling on scale(factor5) Secondly, the following result are derived through a distribution chart on an exhibition room of K-museum. As shown above, this study based on various analyzed aspects proposes the directions of a color image plan to improve stay time in exhibition space of children museums with a hope to support educational goals of experience education-focused children museums.

The effort of implementing realistic 3-D depth on 2-D images has been continued persistently with a theoretical understanding of depth perception and its related technical development. The present article briefly reviews a number of popular stereoscopes for studying stereoscopic depth perception according to their implementation principles, and introduces a behavioral experiment as a technical example in which the active-shutter glasses were used. In the present study, participants were tested for their visual memory against perceived depth among a set of items. The depth of the memory and test items was manipulated to be 1) monocular, 2) binocular, or 3) both-monocular-and-binocular respectively. The memory performance was worst in the binocular-depth condition, and best however in the both-monocular-and-binocular condition. These results indicate that visual memory may benefit more from monocular depth than stereoscopic depth, and further suggest that the storage of depth information into visual memory would require both binocular and monocular information for its optimal memory performance.

Purpose of the study is to explore the effect of the types of mobile coupons(text- vs. image-focused coupons; free-gift vs. discount coupons) on characteristic perception of mobile coupons, and the causal relationships among characteristic perception, attitude, and use intention of mobile coupons. A total of 140 university students participated in experiments with questionnaires including one of the four stimuli. Important findings are as follows. First, image-focused mobile coupons generated more enjoyment than did text-focused coupons. However, the text/image-focused coupons were not different in perception of informativeness and credibility of mobile coupons. Second, enjoyment perception was significantly increased when image-focused contents were combined with discount coupons whereas enjoyment perception was decreased when text-focused contents were combined with free-gift coupons. This interaction effect reflects that the level of enjoyment of consumers can be changed in terms of the combination of the value-provision types of coupons and the text-image focused contents. Third, it was found that consumer perception of coupon characteristics formed attitudes toward mobile coupons, and use intention of mobile coupons was determined by attitudes toward mobile coupons. Study findings may fill the void of research investigating the effect of text-image contents and the types of coupons on consumer reponses toward mobile coupons. Mobile coupons have limited quantity of information within a small size of mobile phone screen, therefore, the results were not consistent with prior research tested with mobile advertisements indicating the effect of text-image contents on perception of informativeness and credibility.

This study, with a space of cafeteria for the object, selected adjective and space for space evaluation based on existing dissertations and experts' survey so as to analyze the perception features by adjective into perception types. At space evaluation, the purpose of visiting the cafeteria was setup for test. Analysis of what perceptual information on the space was acquired enables to set up any features at a space and the direction of designing. The approach through the evaluation of space perception assigning this kind of observing intentionality can be applied to emotion technique which connects a designer to customers. From this study, the following conclusion has been reached. Frist, the difference at perception type by gender is formality, which is higher with women than men. When it is considered that other types are identical, it can be seen that the formality is the perception type to decide the selection of gender and has the highest average value among all the three types. On the whole, men have the tendency for regarding spaciality as the most important, while women have that for looking upon formality as such. Second, to the question what element they would see first when visiting for conversation, men and women answered respectively that they would see partition (35.6%) and chairs (38.0%). Men had a very strong propensity for the element of area section(partition) supporting the activity of purpose and women regarded the element of behavior support(chair) carrying out the activity of purpose as important. Third, the analysis of deviance shown at the formality of perception type showed that men had dispersive selection at the process of selecting all adjectives and their features at the process of space perception were higher than spaciality and fancine.
