Space perception is generally treated as a problem relevant to the ability to recognize objects. Alternatively, the data from shape perception studies contributes to discussions about the geometry of visual space. This geometry is generally acknowledged not to be Euclidian, but instead, elliptical, hyperbolic or affine, which is to say, something that admits the distortions found in so many shape perception studies. The purpose of this review article is to understand perceived shape and the geometry of visual space in the context of visually guided action. Thus, two prominent approaches that explain the relation between perception and action were compared. It is important to understand the fundamental information of how human perceive visual space and perform visually guided action for the convergence on embodied cognition, and further on artificial intelligence researches.

본 연구는 우리말 형용사를 이용하여 각종 생활공간음에 대해 느끼는 사람들이 감성적 반응의 차원을 밝히기 위한 기초 연구로 수행되었다. 형용사 사전에서 추출된 어휘들에 대한 적합성 및 유사성 평가를 통해 14개의 형용사가 최종적으로 선정되었고, 이 형용사들의 유사성 점수에 대해 요인분석, 다차원 척도 분석 및 군집분석을 시행하였다. 연구 결과 생활공간음에 대한 사람들의 감성적 반응은 크게 3가지 차원, 즉 쾌-불쾌, 민감-둔감 및 지각된 크기가 추출되었고, 소음에 대해 느끼는 감성은 이들 차원 상에서 측정될 수 있는 것으로 나타났다. 이들 차원들은 서로 직선적인 관계가 있는 것으로 보인다. 즉, 소음에 대해 민감한 사람은 그 소음에 대해 불쾌하거나 짜증을 일으키기 쉽지만 소음에 대해 불쾌하거나 짜즈을 일으킨 사람이 소음에 대해 민감한 사람이라고 볼 수는 없을 것이다. 따라서 이들 차원간에 구체적인 통로분석이 이루어져야 할 것으로 보이며 이는 후속연구에서 밝혀질 것이다. 또한 실제 소음을 제시하여 각각의 소음을 평가하는 경험적 연구도 수행될 것이다.

Many companies are increasing the use of characters to enhance brand image and brand value. The use of characters in the certain industry is active, however, the research on characters in academia is insufficient. The purpose of this study is to investigate how characteristics of characters affect on consumer's brand attitude and to suggest the guideline companies to concern on brand characters, in especial on designing or licensing them. The results showed that all characteristics of character positively influenced on brand attitude. Among nine characteristics of the character, trust was the most impact and nostalgia was the least impact on brand attitude, respectively. Perceived quality was mediated on in relations between the brand character and brand attitude. In indirect effect, familiarity was the most impact on brand attitude. In sum, we suggested that trust and familiarity of the character are the most weighted characteristics on brand character design strategy.

Purpose: The purpose of the present study was to identify factors affecting anxiety about disaster damage potential in Gyonggi-do and evacuation behavior that influences evacuation behavior. Method: Multiple regression analysis was performed to test the hypothesis and to analyze the influence of anxiety about disaster damage potential and perceived stress, and analyzed similarity in correspondence between age and anxiety about disaster damage potential. Results: The anxiety about disaster damage potential of a group vulnerable to safety and anxiety about disaster damage potential of disaster system collapse were perceived in close proximity. Disaster system collapse, evacuation life, and natural disasters were found to be factors affecting perceived stress. Stress and natural disasters were found to be influencing factors on evacuation behavior. Conclusion: The necessity of managing stress was confirmed since anxiety about natural disaster damage potential and stress affect evacuation behavior. The recent experiences of heavy rain disasters indicate that the anxiety about disaster damage potential is expected to increase. The findings also indicate the importance of preventive planning and psychological management to manage the anxiety about disaster damage potential.

This study examined the perceived fit between the characteristics of immersive technology and the type of media art affects commitment, satisfaction, and revisit intention. The results showed that the quality of projection mapping and the reputation of original art had a positive effect on the perceived fit whereas the accessibility of original art had a negative effect on the perceived fit. In addition, the reputation of original art and the perception of fit increased the commitment of the media art exhibition, which positively affected the satisfaction and revisit intention. This study provides theoretical and practical implications regarding the effect of immersive technology and media art type of digital media art.

This research focuses on the theory of Zhi-jue(知覺) by Kim Chang-Hyup(金昌協) through comparison between Kim Chang-Hyup's and Zhu Xi(朱熹)'s. In the point of supervision, Zhu Xi considered that Zhi-jue is one of the conditions caused by supervision, one the other hand, it is the action that make possible supervision. Kim Chang-Hyup emphasize the concept of Zhi-jue itself, he considered that Zhi-jue is the action that make possible supervision, and separate Zhi-jue from Xing(性) or Qing(情). In this process, Zhi-jue became the subject itself about supervision, so the mix about relation between Zhi-jue and supervision is solved. But there is a problem about gap between Zhi-jue and the nature from separate between Zhi-jue and Xing. Kim Chang-Hyup intend to separate Zhi-jue and Qing as subject and object, so he considered that Xing is not a reason of Zhi-jue, but rules. It's not a answer about what is the reason of Zhi-jue. Yet Zhu Xi also considered that Xing is the rules of Zhu-jue, only in the case that Zhi-jue means the resulf of supervision, Zhi-jue is considered as the effect of Zhi(智). So the relation problem about Zhi-jue as a subject and the nature is brought up by Joseon scholar who attempted to arrange the concepts of neo-confucianism. Eventually, in case of the relation about Zhi-jue and Xing, King Chang-Hyup and Zhu Xi has a common point, only in case of the relation about Zhi-jue and supervision, Definding Zhi-jue as the subject of supervision is the character of Kim Chang-Hyup's theory of Zhi-jue.

The chemical composition of the continental crust play an important role in understanding of crustal formation and evolution and quantifying other processes taking place within continental crust. We summarized geochemical data reported in the previous literature for the crustal rocks in the Korean Peninsula and divided their chemical composition into geologic time scale. In the variation diagram normalized by average composition of the upper crustal rocks, the geochemical characteristics of the upper crust during Triassic period is different from those of the upper crustal rocks after Jurassic period or before Precambrian. However, the geochemical characteristics of the Jurassic and Precambrian period are similar each other. Our summarized data indicate that the source material of Triassic upper crust may be different from that of Jurassic or Precambrian upper crust.

This study: 1) identifies differences in consumers' perceived similarity of extended products to their parent product in terms of brand attributes, 2) identifies the influence of the perceived similarity on consumer's attitude toward and purchase intention of extended products (i.e., brand extension effect), and 3) examines the moderating effect of Brand Relationship Quality (BRQ) on brand extension effects. A survey questionnaire was distributed to a convenience sample of individuals aged 20-39. A total of 576 valid responses were used for the final analysis. The results showed that: 1) the consumers perceived more similarity in the extended products when the extended products maintain more consistent attributes with their parent product, 2) the higher the perceived similarity was then the higher the brand extension effect, and 3) brand relationship quality moderated the influence of perceived similarity on attitude and purchase intention. When consumers build a high relationship quality with a brand, then the brand extension effect is likely to be high regardless of the perceived similarity of the extended products. This study consequently has its own contribution in that it empirically examined the brand extension effect in the fashion field and evidenced the role of BRQ in brand extension.

Lavie's perceptual load theory (Lavie, 1995) proposes that the influence of distractors would be blocked as the load gets higher. Studies of perceptual load have usually adopted the flanker task, developed by Eriksen and Eriksen (1974), which measures reaction time on the target flanked by distractors. In the post-cueing forced task, participants should report the identity of the target cued later, and negative repetition effect (NRE) has often been observed. NRE means the effect that the accuracy of identification is worse when the target is flanked by the same nontargets than when flanked by different nontargets. This study has tried to check whether perceptual load has an effect on identification rate and NRE. Experiment 1 manipulated the similarity between targets and a distractor, and observed a tendency of NRE, but not the effect of perceptual load. Experiment 2 used 4, 2 (in two kinds of diagonal arrangement), or none distractors of the same identity to burden more perceptual load. NRE was significant and perceptual load showed significance but not a linear trend. Experiment 3 checked again whether NRE would be varied according to two levels of perceptual load strengthened by positional variability of load stimuli, but did not find the effect of perceptual load. It is concluded that perceptual load might have a limited effect on the early stage of perceptual processing due to divided attentional processing of the targets briefly exposed. Implications of this study were discussed.
