The purpose of this study is to investigate and analyze the understandings of elementary pre-service teachers about 'estimation' in the elementary mathematics. Together with this analysis, we identify elementary pre-service teacher's Mathematical Pedagogical Contents Knowledge(MPCK), especially focusing to Subject Matter Knowledge(SMK). In order to this goals, we investigate contents relating to 'estimation' from $1^{st}$ curriculum to 2009 revised curriculum and compare 'rounding up', 'rounding off', 'rounding' in the elementary mathematics textbooks. As results of investigations, 'estimation' has been teaching at the 'Measurement' domain from $3^{rd}$ curriculum, but contexts of measuring weaken from $7^{th}$ curriculum. 'Rounding up(off)' is defined three types in the textbooks from $1^{st}$ to 2009 revised curriculum. And we examine elementary pre-service teachers through the questions on these 'estimation' contents. On the analysis of pre-service teacher's understanding relating MPCK, four themes is summarized as followings; the understanding of '0' in the 'rounding up', the cognitive gap between 'rounding up' and 'rounding off', the difference of percentage of correct answers according to types of question in the 'rounding up', and the difference between the definition of 'rounding up' and the definition of 'rounding'.

This research focuses on the relationships among customer satisfaction, delight, and loyalty. Although customer delight is one facet of an affective evaluation that can be predicted from customer satisfaction as cognitive component of the evaluation, there is no empirical examination on the casual relationship among customer satisfaction, delight, and loyalty. This study aims at addressing this gap in the service literature. The research questions are (1) How is customer satisfaction related to customer delight? and (2) Does customer delight matter in the relationship between customer satisfaction and loyalty? Data from a survey of consumers across upscale restaurant and retail bank in Korea were obtained. Our results show that customer satisfaction contributes positively to customer delight, and that customer delight plays a significant role in the relationship between customer satisfaction and loyalty. This chained relationship from customer satisfaction to customer delight to customer loyalty suggests that achieving customer delight represents one of the underlying pathways through which basic or core requirements expected by customers are satisfied. Our finding suggests that service firms need to monitor and manage their levels of customer delight as a performance metric, and delighting customers may be an important strategy to build competitive advantage through customer loyalty.

The stepping stone of the study is provided through understanding the transformation of the cultural value with the paradigm shift at the turning point of late 20th century and examining the cultural relationaship between the East and the West. By researching the oriental and occidental culture in terms of the origin formation relation and differences which should be divided into broad branches that is natural ideological formative and spatial aspects and so forth. This paper makes it possible to understand the fundamental differences and relativities between two divergent cultures by way of analyzing the architecture in plastic and cognitive aspects to residential space. this study intends to elucidate common traits of korean traditional architecture and that of the Occident and the discrepancies of their attitudes toward nature and space. In Western civilization they used to consider architecture as a physical organization while the oriental people consider it a object what is so of itself. The former concentrated on the functional rationality of scientific technology with the uncontextual propensity which does not consider natural environment the latter could reach the naturalness more harmonious to environment. What counts in the upcoming age of coexistence of Globalism that emphasizes the worlds universality and Nationalism that sticks to local cultural characteristics is to establish the new value system and identity based upon natural order and organic quality. As a result we could recognize the organic quality as a cosmic order could be a valid means to achieve the globalization of our culture through the compatibility between gap and common ground of both cultural sphere.

Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.

As the gap between competing products narrows in terms of performance and quality, the product usability is rapidly becoming a new dimension of product design as the key to offering distinctive value to the customer. Because the user interface is important, not only for the user but also for the efficiency of te whole organiation, system designers require increasingly precise evaluation methods to determine how effective and usable human-product interface is. In this study a new methodology named usability analysis diagram(UAD), for evaluating usability of human-product interface systematically, was developed. UAD is a top-down flow diaagram of a human-product interaction, in ehichfour basic elements - perception, understanding, intellectual decision and action - were classified and then represented by a particular symbol for each. The usability of the product is assessed by the frequency of each symbol in a diagram which represents a sequence of cognitive and physical activities of users during the use of the product, and by the level of difficulty that is classif- ied in three levels in terms of easiness of perception, understanding and action. In order to test validity of the proposed UAD in a real situation, a case study was performed on two different cameras, automatic and manual, and their usability was successfully evaluated and compared.

Due to characteristics of modern society including technological development, various methods engaging interaction between people and manmade environment have become one of the major issues raised in various fields of deign so called interactive design. Interactive design started as the interface between human and computer system, but now expanded to interior design field enhancing spatial experience of users. Now, many corporates are looking into interactive design to bridge the gap between company or brand identity and consumers as marketing tool. The current study investigates interactive concepts and characteristics of corporate participated public spaces and tries to define their design methods according to spatial marketing strategies. Using theoretical inquiry, cultural events and delivery of corporate identity information were defined as two major spatial strategies through cognitive or behavioral approaches. Moreover, digital, constructive, and expressive presentations were found to be most common design methods. Through this theoretical framework, 7 selected samples in Korea are analyzed in order to find detailed design characteristics. It is hoped that this study may serve in understanding current design approaches of interactive corporate public spaces and useful guideline when designing interactive public spaces not only as means of marketing strategies but even for public goods.

This paper aims to explore instructional design of a cyber classroom for secondary students' basic English language competence. A paucity of support for low or under achieving students' English learning exists particularly at the secondary level. In order to bridge the gap, there has been demand for online educational resources considered to be an effective tool in improving students' self-directed learning and motivation. This study employs a comprehensive approach to instructional design for the asynchronous cyber classroom with the underlying premise that different learning theories can be applied in a complementary manner to serve different pedagogical purposes best. Gagné's conditions of learning theory, Bruner's constructivist theory, Carroll's minimalist theory, and Vygotsky's social cognitive development theory serve as the basis for designing instruction and selecting appropriate media. The ADDIE model is used to develop online teaching and learning materials. Twenty-five key grammatical features were selected through the analysis of the national curriculum of English, being grouped into five units. Each feature is covered in one cyber asynchronous class. An Integration Class is given at the end of every five classes for synthesis, where students can practice grammatical features in a communicative context. Related theories, pedagogical practices, and practical web-design strategies for cyber Basic English classes are discussed with suggestions for research, practice and policy to support self-directed learning through a cyber class.

Purpose: This study investigates the psychological mechanisms of comparison within the design context of retail stores, products, and advertising. The research aims to expand the understanding of comparison psychology, encompassing social, cognitive, perceptual, and self-comparisons and their application in design practices. Research Design, Data, and Methodology: The study employs a comprehensive review of psychological theories related to comparison psychology. They were selected through extensive research on literature pertaining to design psychology and consumer behavior. The research integrates insights from psychology, marketing, consumer behavior, and design theory, supported by various design examples of retail stores, products, and advertising, to demonstrate the practical applications. Results: The findings reveal that comparison psychology significantly impacts consumer preferences and user experiences. For instance, the assimilation effect and prospect theory highlight how comparisons shape value judgments and design perceptions. Practical examples are used to illustrate the profound influence of comparative judgments in design. Conclusion: The study advocates for a "psychologically-informed approach" to design, promoting designs that are not only aesthetically pleasing and functionally sound but also psychologically aligned. By bridging the gap between psychological theories and practical design implementations, the research provides valuable insights for designers, marketers, and psychologists, enhancing the psychological efficacy of design.

Study about existence of illusion which human beings feel from imitated image based reality have been continuing by copy theory and conventionalism for a long time. Traditional copy theory which had controlled representation theory from plato have explained illusion by similarity of image and representation objects. According to copy theory, image is natural sign unlike language but the late in the 20th century, conventionalism from N, Goodman insists they are not any special similarity between image and representation objects. They insist image and conventional sign just as language. These opposit theory rearranged conventionalism by the entrance on the cognitive science. The copy theory couldn't explain the problem of representational gap between reality and duplication, but photo media makes new paradigm about theory of the illusion. The problem of representational gap was disappeared by CGI images on the base of digital media. We are exposed exquisite duplication for a example, movie, advertisement, printings. Sometimes duplications are more real than the original works. Digital is a non-material object by 0 and 1. Specially real lighting skill and mechanism are copied perfectly by photon mapping skills and the duplications are produced more real than the original works. By disappearance of representational gap, we need new theory model for explaining of digital illusion and copy theory can be the key.

Some progress has been made in the study of the category coherence effect, which states that the attributes of soldiers or nuns with similarities in dress and behavior, and easily distinguished from other categories, are likely to be generalized. However, few studies have examined the fundamental psychological mechanisms that underlie this category coherence effect, and this study aims to fill this gap. For this purpose, two experiments were conducted after selecting categories with high coherence (nuns, soldiers, and flight attendants) and those with low coherence (interpreters, wedding planners, and florists). In experiment 1, we observed that the members of a category were presumed to have certain reasons to prefer [property X] (presumption of reasons for preference), with this presumption becoming stronger when [property X] was observed repeatedly in high-coherence categories than in the case of low-coherence categories. Experiment 2 showed that for the high-coherence categories, the presumption of reasons for preference was stronger when [property X], rarely seen in everyday life (base rate of 30%), was observed, while the presumption of reasons for preference was weaker when [property Y] (base rate 70%), frequently seen in everyday life, was observed. In the low-coherence categories, the presumption of reasons for preference tended to be weak for both rare and frequent attributes. That is, there were significant effects of the two-way interaction between category coherence and base rate on the presumption of reasons for preference. This study has implications for psychological essentialism and stereotyping.
