The statistical graphics is a design field focusing on the user perception aspects for the correct information delivery and the effective understanding, with the use of the quantitative data through the information analysis, extraction, visualization process. The statistical graphics with the big data composition factor is termed as the statistical big data graphics. In the statistical graphics the visual factors are used to reduce the errors in the perception part and to successfully deliver the information. However, in the statistical big data graphics the visual factors of the enormous data are causing the cognitive discouragements. The purpose of this study is to extract the cognitive discouragement factors from the big data statistical graphics, categorizing the types of the statistical big data graphics as 'network type', 'segment type', and 'mixed type', based on their compositional shapes, and explored the characteristics according to them. Especially, based on the visual main factors in the statistical big data graphics, We extracted the cognitive discouragement factors that appear in the high visualization as the four categories: 'multi-dimensional cases', 'various color', 'information overlap', and 'legibility of the writing'.

색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시킨다는 연구결과(Stoner & Albright, 1997)와 색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시키지 못한다는 상반된 연구결과(Edwards & Badcock, 1996)의 모순을 해결하고, 선택적 주의에 따른 목표자극과 방해자극의 분리가 2차원 운동지각에 미치는 영향을 연구하기 위하여 일련의 실험이 수행되었다. 이러한 연구문제에 대한 이형철(1999)의 연구가 있었지만, 이형철의 연구는 단지 숙련된 2명의 피험자의 결과에 의존했다는 점, 그리고 선택적 주의에 사용된 자극에서 목표자극과 방해자극이 색채에 의해 완벽하게 분리되지 않을 때와 목표자극과 방해자극이 색채정보에 의해서만 분리되고 그 외의 다른 정보에 의하여 분리되지 않을 때와 목표자극과 방해자극이 그 어떤 정보에 의해서도 분리되지 않을 때, 피험자들의 2차원 운동지각 수행은 비슷하였다. 하지만, 목표자극과 방해자극이 색채정보에 의하여 분리되고 피험자들이 목표자극을 구성하는 색채에 선택적 주의를 기울일 때, 피험자들의 2차원 운동지각 수행은 향상되었다. 이러한 실험결과는 선택적 주의가 개입되지 않는 한 인간의 운동지각체계는 자극 구성요소들을 운동정보분석을 위해 색채에 따라 자동적으로 grouping 하지 않음을 의미한다

Achieving consistent geometric design is an important goal in highway design to ensure obtaining safe, economical and smooth traffic operation. Most evaluation of consistency is based on 'speed change' in speed profile. According to literature, the speed depends on geometric elements, speed on tangent section prior to a curve, and background around roads. Especially, the radius is the most main element mentioned in various literature. Therefore, this paper shows two ways of calculating horizontal radius on real road, that is, three-dimensional road. First of all, the radius of horizontal curve is calculated based on physical method. The calculated radius contains not only superelevation but also longitudinal grade while the current minimum radius is calculated by considering superelevation and side friction according to the point-mass equation. Secondly, the problem of composed curves with distorted appearance by overlaying sag or crest vertical alignment has been known. To quantify the extent of distortion effects, the method of calculation of real seen so called 'Perspective Radius' is developed. The paper presents the perspective radius and recommended perspective radius.

This study examined the factors that can enhance the continuity of user experience in multi - device environment. First of all, regarding the structural difference and continuity of tasks, functional differences such as OS difference according to the characteristics of cross media, use of mouse and touch gesture were found to interfere with continuity. To increase continuity, metaphor and ambience To increase relevance and visibility. In the continuity part of visual memory and cognition, familiarity was given by the identity and similarity of visual perception elements, and it was found that familiarity factors are closely related to continuity. Finally, for the continuity of the user experience, we can see that the visibility factors as well as the meaning and layout consistency of the information are factors for the continuity of the user experience. Based on this, it was found that familiarity, consistency, and correlation were significant influences on continuity dimension of user experience, but visibility did not have a significant effect on continuity when regression analysis was conducted as factors of familiarity, consistency, correlation and visibility.

Recently, there is a tendency of consumer's participation gradually increasing in the design shaping process. Consumers make evaluation or suggestion about the shape of the product, and the industries lay out schemes to elicit consumers' participation. However, when it comes to dealing with the shape of the product, consumer and designer has a fundamental difference in their point of view, and it works as interruption to the efficient communication between the consumer and designer. Therefore, this study will examine the difference of consumer's and designer's view of products' shape, and the guidelines of effective molding which elicit the consumers' affective responses. First, I established the sensible image vocabulary based on the shape of the product. And based on the vocabulary, I carried out the same experiments to the consumers and designers. As a result, the affective responses of the two groups toward the shape have similar characteristics and designers' reactions found out to be more dramatic than consumers.

This study is to examine relationship between immersiveness aspect and the recognition of garners who are exposed to PPL (Product Placement Advertisement) in online game. The frequency of exposure, the placement type of PPL, the perception under the threshold of consciousness and the interest at the product and knowledge about PPL have been widely known as the factors of effectiveness in PPL advertising. In this study, 'immersiveness' is newly introduced to investigate the effectiveness of PPL advertising due to the unique characteristics of game which easily leads to immersion. Control group is exposed to movie clip and experimental group to lacing online game. In conclusion, the deep immersion has reduced the perception level of user on PPL except the variable of PPL placement. This study suggests that how to design the PPL placement in game for enhancing marketing effect is all the more vital, in spite of the result that the player in high immersion cannot distinguish different images.
