This study evaluates the difference in visual images according to changes in waist position and pants style. The researcher made twelve stimuli-combination of four pants styles (classic, baggy, skinny, bell-bottom) and three waist positions (0cm, -3cm, -5cm). The test involved 48 female college students. The stimuli were made using the i-Designer computer program. The panels tested the screen images of all manikins wearing pants. A 7-point scale was used to evaluate each image. For the data analysis, the ANOVA and Duncan-test were applied along with an SPSS program. The results of this study are as follows. The visual evaluations by pants style and waist position are composed of seven factors (attractiveness, attention, hip, activity, height, waist, abdomen). Among these factors, attractiveness is evaluated to be the most important factor. The mutual agreement of the visual effect (according to pants style and waist position) was indicated as four factors of attractiveness, attention, waist, and abdomen. The height factor is evaluated to be the most important factor by change in regards to waist position. The 0cm waist position of three styles (classic, baggy, bell-bottom) were evaluated positively in elongated height whereas the -3cm, -5cm waist position of the skinny style was evaluated positively in elongated height. The mutual agreements of visual effect (according to pants style and waist position) were not indicated.

Cityschumers experience the urban with the visual perception while walking an average speed of 4km per hour. At this time, recognition of the color field accounts for more than 70%. Therefore, in this paper the environmental color of urban street is examined by dividing the pedestrian visual field area. In the urban street, the area of the visual field area of the pedestrian is divided into Ground Plane, Roadside, Canopy and Building Wall. In addition, we observe and color survey the environmental color of Exhibition Road, which is the northern side space of South Kensington in London, which adopted the world's first shared space. The color of the visual filed area was dominated as YR, GY, Y, PB. The Ground Pland was dominated by the YR. The reason for this is that the color of the floor has changed due to the shadows of surrounding architecture and facilities. Roadside was dominated in various ways such as GY, BG, PB, B and P. Canopy was mainly composed of PB, GY, etc. It was found that the material color of the lower part of the architecture was reflected. The architecture wall was affected by the reflectance and absorption rate of the transparent material. The first image that comes to mind when thinking about the urban is the street where pedestrians walk, feel and enjoy themselves. Therefore, it is suggested that various policy frameworks for managing and managing urban planning professionals may be different from the perceptions of pedestrians active in mega cities.

Recently, the target object can be represented as sparse coefficient vector in visual tracking. Due to this reason, exploitation of the compressibility in the transform domain by using L1 minimization is needed. Further, L1 minimization is proposed to handle the occlusion problem in visual tracking, since tracking failures mostly are caused by occlusion. Furthermore, there is a weighted parameter in L1 minimization that influences the result of this minimization. In this paper, this parameter is analyzed for occlusion problem in visual tracking. Several coefficients that derived from median value of the target object, mean value of the arget object, the standard deviation of the target object are, 0, 0.1, and 0.01 are used as weighted parameter of L1 minimization. Based on the experimental results, the value which is equal to 0.1 is suggested as weighted parameter of L1 minimization, due to achieved the best result of success rate and precision performance parameter. Both of these performance parameters are based on one pass evaluation (OPE).

White light MTF(Modulation Transter Function)s of biconvex trial lenses from 10 to 20 diopter (D) were represented as a function of angular frequency and visual acuity, and then they were compared with AIM(Aerial Image Modulation) curves. All of the biconvex trial lenses evaluated in on-axis mode had MTF performance that could resolve Landolt's ring up to visual acuity 2.0. However, in a half field angle of five degrees, the trial lens of 10 diopters was able to resolve Landolt's ring up to visual acuity 0.9, and that of 20 diopter only up to visual acuity 0.8. This means that the trial lenses in the case of a half field angle of five degrees do not have sufficient resolution to measure visual acuity by 1.0.

The purpose of this study is to analyze the change of visual stimulus of users to the space through the experiment of EEG and the satisfaction of users depends on the lighting. To do that, the results measured with EEG experiment focusing on Beta ${\beta}$ were compared to each other to figure out difference in the changes of the activation of human brain on lighting's situation as the lighting off and on in the same space. The difference in the results was verified according to the characteristic of users which classified with 4 types of the spatial sensitivities. The results of this study are as following. Firstly, the spacial sensitivity of user is to communicate well with the different senses with stimulus through interaction among the elements. At this time, the brain plays a major role in build the spacial sensitivity of users as the place to make form. Secondly, there are the differences in the activation of brain depends on lighting situation even in the same space. The stimulus into the brain became generally stronger in images with lighting on than off. Especially, the response in the occipital lobe which connected with the visual center turn out strongly in the image of 'modern natural'. Because the visual stimulus interact well with the bright color, the reflectional texture and the rough texture painted the dark color. Thirdly, the satisfaction of users changed with lighting in the space. But we could know that the satisfaction of users isn't be related to the visual stimulus through the results of this study. Finally, there isn't the difference in the activation degree of brain according to the characteristic which are preference of users into 4 types of the spatial sensitivity through the results came from ANCOVA(analysis of covariance) with SPSS Program 22.

Purpose: To investigate the genetic association of visual acuity(VA) between young children, schoolchildren, juveniles, and their parents. Methods: 208(4 to 18 yrs) subjects who are belongs to young children, schoolchildren and juveniles and 340 their parents were assessed. Corrected and uncorrected visual acuity in each eye were measured using Han's test chart(5m). Results: There was no correlation with father's VA on under 6years but mother's VA tend to effect on male children. In case of elementary school students, their VA shows strong correlations with their parents VA; VA uner 0.7 group shows both parents VA was under 0.7 and VA over 0.7 group tend to shows their parents VA was over 0.7. Moreover, in juvenile, there was strong correlation between mother's VA and male children's VA. Conclusion: Our study showed that the family history, especially mother's visual acuity, had more effect on the problem of their children's visual acuity.

Background and Objectives: The influence of visual stimulus on the auditory component in the perception of auditory-visual (AV) consonant-vowel syllables has been demonstrated in different languages. Inherent properties of unimodal stimuli are known to modulate AV integration. The present study investigated how the amount of McGurk effect (an outcome of AV integration) varies across three different consonant combinations in Kannada language. The importance of unimodal syllable identification on the amount of McGurk effect was also seen. Subjects and Methods: Twenty-eight individuals performed an AV identification task with ba/ga, pa/ka and ma/ṇa consonant combinations in AV congruent, AV incongruent (McGurk combination), audio alone and visual alone condition. Cluster analysis was performed using the identification scores for the incongruent stimuli, to classify the individuals into two groups; one with high and the other with low McGurk scores. The differences in the audio alone and visual alone scores between these groups were compared. Results: The results showed significantly higher McGurk scores for ma/ṇa compared to ba/ga and pa/ka combinations in both high and low McGurk score groups. No significant difference was noted between ba/ga and pa/ka combinations in either group. Identification of /ṇa/ presented in the visual alone condition correlated negatively with the higher McGurk scores. Conclusions: The results suggest that the final percept following the AV integration is not exclusively explained by the unimodal identification of the syllables. But there are other factors which may also contribute to making inferences about the final percept.

Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

One of the goals of this article is to continue the momentum begun by emerging scholarship on theory and practice of writing about visual culture of and in Southeast Asia. I hope to offer culturally sensitive and embodied ways of looking at images and objects as sites/sights of cultural knowledge as further theoretical intervention. The argument put forward in my essay is three-fold: first, I critique the prevailing logocentric approach in the field of Southeast Asian Studies and I argue that in a postcolonial, global, and transnational period, it is important to be inclusive of other objects as sites/sights of social, political and cultural analysis beyond written and oral texts. Second, I argue that although it has its own political and theoretical problems, the evolving field of Visual Studies as it is practiced in the United States is one of many ways to decolonize the prevailing logocentric approach to Southeast Asian Studies. Third, I argue that if one reads these Euro-American derived theories of vision and visuality through the lens of what Walter Mignolo calls "colonial difference(s)," then Visual Studies as an evolving field has the potential to offer more nuanced local ways of looking at and understanding objects, vision, and visuality. Last, I point out that unlike in the West where there is an understanding of pure, objective and empirical vision, local Southeast Asian perspectives on objects and visions are more embodied and multi-sensorial. I argue that if one is ethically mindful of the local cultural ways of seeing and knowing objects, then the evolving field of Visual Studies offers a much-needed intervention to the privileged, lingering logocentric approach to Southeast Asian Studies. Moreover, these alternative methods might help to decolonize method and theory in academic disciplines that were invented during the colonial period.
