This paper reports on a study testing a model of relationship quality in the context of new versus mature export-import relationships. The model posits that perceived similarity, relationship performance, and opportunism predict relationship quality, moderated by relationship duration. The model also posits relationship quality affects commitment. A survey of importers with regard to their relationships with foreign exporters was conducted to test the model. It has been found that perceived similarity has a significant effect on relationship quality at the early stage of the relationship, but not at the later stage of the relationship. It also has been found that relationship performance and opportunism have significant influence on relationship quality. Regardless of relationship duration, the study results provided good support for our model. Theoretical and managerial implications of the study results are discussed.

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.

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.

Twelve Japanese students living in South Korea have been examined for their perceptual identification of an initial consonant in Korean syllables with or without a white noise. A confusion matrix was then subject to analyses of additive clustering, individual difference scaling, and probability of information transmission, the results of which were also compared to those of South Koreans. The Japanese in the present experiment confused /다/and/타/ most frequently, followed by /가/ and /카/, /자, 차, 짜/, /타/ and /따/, and so on. The results of additive clustering analysis of the Japanese significantly differed from those of the South Koreans. Individual difference scaling revealed dimensions of sonorant, aspiration and coronal. While South Koreans showed binary values on aspiration and tenseness dimensions, the Japanese did continuous values on such dimensions. An information transmission probability analysis revealed that the Japanese participants could not perceive very well such larynx features as tenseness and aspiration compared to the South Korean participants. The former group, however, perceived very well place of articulation features such as labial and coronal. The present results suggest that an approach dealing with structures of base representations is important in understanding the phonological categories of languages.

In this paper, we propose a similarity search algorithm for image databases. One of the central problems regarding content-based image retrieval (CBIR) is the semantic gap between the low-level features computed automatically from images and the human interpretation of image content. Many search algorithms used in CBIR have used the Minkowski metric (or $L_p$-norm) to measure similarity between image pairs. However those functions cannot adequately capture the aspects of the characteristics of the human visual system as well as the nonlinear relationships in contextual information. Our new search algorithm tackles this problem by employing new similarity measures and ranking strategies that reflect the nonlinearity of human perception and contextual information. Our search algorithm yields superior experimental results on a real handwritten digit image database and demonstrates its effectiveness.

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.

In recent years, Super-pixels have become very popular for use in computer vision applications. Super-pixel algorithm transforms pixels into perceptually feasible regions to reduce stiff features of grid pixel. In particular, super-pixels are useful to depth estimation, skeleton works, body labeling, and feature localization, etc. But, it is not easy to generate a good super-pixel partition for doing these tasks. Especially, super-pixels do not satisfy more meaningful features in view of the gestalt aspects such as non-sum, continuation, closure, perceptual constancy. In this paper, we suggest an advanced algorithm which combines simple linear iterative clustering with fuzzy clustering concepts. Simple linear iterative clustering technique has high adherence to image boundaries, speed, memory efficient than conventional methods. But, it does not suggest good compact and regular property to the super-pixel shapes in context of gestalt aspects. Fuzzy similarity measures provide a reasonable graph in view of bounded size and few neighbors. Thus, more compact and regular pixels are obtained, and can extract locally relevant features. Simulation shows that fuzzy similarity based super-pixel building represents natural features as the manner in which humans decompose images.
