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.

The purpose of this paper was to introduce sociocultural theory which is a different epistemological perspective from constructivism and to understand the sociocultural theory in a systemic way by providing four specific criteria for a sociocultural theory from the analysis of Vygotsky's ideas. The four criteria are the followings: first, the origin of learning is not at the individual level, but at the social. Second, Learning takes place in a sociocultural framework through ZPD and there exists the stage of pseudo concept before it gets to a true concept. Third, a clear focus on action, especially mediated action, and the concept of psychological tools should be discussed in the boundary of a sociocultural theory. Fourth, actors in a learning process are not an individual child alone. In consequence, the role of adults, particularly teachers, are significant in a child's learning, and this fact provides a great potential for the active role of teachers in the students' learning of mathematics from the sociocultural perspective.

After 1960s, a radical change was taken place in the modern urban theories which were developped by many architects and planners like Ebenezer Howard, Tony Garnier, Le Corbusier, Ludwig Hiberseimer, and Patrick Abercrombie. Many contemporary architects like Kevin Lynch, Aldo Rossi, Christopher Alexander, Colin Rowe, Rem Koolhaas, and Bernard Tschumi have a view that modern urban theories lost their abilities to organize and control new realities so that new urban theories was needed in order to cope with urban problems in the 1960s. In this study, we are to examine contemporary urban theories in comparison with modern urban theories and to clarify the role of discourse of language in its emergence. In consequence we can detect four main themes in the process of transformation from modern urban theories to contemporary urban theories : from functionalism to formalism, from historicism to archeology, from space to placeness, and from hierarchical organization to network. And we can prove that such themes basically depend on the discourse of language.

A theoretical attempt is made to analyze the dynamic contact force and response of laminated composite beams subjected to the transverse impact of steel balls. A beam finite element model based on the modified theory for laminated composites in conjunction with static contact laws is formulated for the theoretical investigation. Finally, it is shown that the present results are in good agreement with some existing solutions or wave propagation theory.

In this study, it propose a proof theory method for expressing and reasoning knowledge in a multiagent environment. Since this method determines logical results in a mechanical way, it has developed as a core field from early AI research. However, since the proposition cannot always be proved in any set of closed sentences, in order for the logical result to be determinable, the range of expression is limited to the sentence in the form of a clause. In addition, the resolution principle, a simple and strong reasoning rule applicable only to clause-type sentences, is applied. Also, since the proof theory can be expressed as a meta predicate, it can be extended to the metalogic of the proof theory. Metalogic can be superior in terms of practicality and efficiency based on improved expressive power over epistemic logic of model theory. To prove this, the semantic method of epistemic logic and the metalogic method of proof theory are applied to the Muddy Children problem, respectively. As a result, it prove that the method of expressing and reasoning knowledge and common knowledge using metalogic in a cooperative multiagent environment is more efficient.

This study applied the Theory of Reasoned Action by Fishbein & Ajzen(1975) as the grounded theory and adopt sanctions of the General Deterrent Theory and protection motivation of the Protection Motivation Theory as the antecedents to discuss the theoretical factors and the cases of application in the field of information security. Then, it adopted subjective norm, a variable of the Theory of Reasoned Action, as a parameter to analyze the causality of sanctions, perceived vulnerability, response cost, and self-efficacy with the intention to follow the information security policies. As a result, all of the antecedents except for sanctions had causality with the intention and subjective norm proved its mediating effect as a parameter between the antecedents and the intention.

This study examined the concept and essence of archetype theories of Johann Wolfgang von Goethe, Rudolf Steiner and Carl Gustav Jung, which theatrically influenced Michael Chekhov. It analyzed how archetype theories were applied in Chekhov's Psychological Gesture and tried to fundamentally understand Chekhov's Psychological Gesture that embraced archetype theories. The concept of archetype repeatedly appears in Chekhov's Psychological Gesture. Chekhov stated that archetype exists in the inner psychology or instinct of the actors and he defined the Psychological Gesture as an archetypal gesture. While exploring references regarding archetype in Chekhov's Psychological Gesture, this study found that it is closely related to archetype theories. Therefore this study thoroughly analyzed Goethe's archetype theory(archetypal plant), Steiner's archetype theory(4 temperament archetypes, 7 human's soul archetypes), Jung's archetype theory(collective unconscious and 4 archetypes, 12 personality archetypes) and it confirmed that archetype theories had a significant influence on Chekhov's Archetype Theory and Psychological Gesture. Goethe and Steiner's archetype theories, Eurythmy are applied to theater education and actor's acting. Likewise, Jung's archetype theory is also adopted theatrical studies and theatrical psychotherapy. The author believes that Chekhov's Archetype Theory and Psychological Gesture influenced by archetype theories will significantly help an actor analyze characters in the play and portray them in creative acting.

The ownership structure of a franchise system is determined by the franchisor's strategic choice. A close look at the extant theories and perspectives in economics and management such as resource scarcity theory, agency theory, transaction cost analysis, and mixed ownership theory reveals that firms choose their ownership structure for the sake of economic efficiency, profit potentials, the chance of survival, and other strategic concerns. The present study, on the basis of strategic choice perspective, reviews the divergent theories of a franchise system's ownership structure and its determinants, thus providing a theoretical framework for comparing the contradictory arguments along the several critical dimensions. We also developed and tested the conflicting hypotheses regarding key determinants of ownership structure including firm's age, size, transaction-specific investments, uncertainty, and risk-sharing propensity. Using a FDD (Franchise Disclosure Document) data set of 543 Korean franchisors, we found that the years in business, the total number of employees, days of training, the inverse of the years of franchising, and the requirement of royalty payment have positive relationships with the proportion of company-owned outlets to total number of outlets. On the other hand, the proportion of company-owned outlets was found to have negative relationships with the total number of outlets and the extent of geographic dispersion of outlets, but to have no significant relationships with the initial investment required and the inverse of contract length. Based on the findings, we provide several theoretical and managerial implications for studying ownership structure of franchise systems.

This article explores early childhood teachers' practices from bottom-up perspectives on the relationship between theory and practice. Results of the review of literature are as follows: 1) From top-down perspectives early childhood teachers' practices and their classroom behaviors have been traditionally defined within the framework of theories of child development, the notion of developmentally appropriate practice, and designed program models; 2) From bottom-up perspectives researchers have a focus on how teachers' practices lead theories and how they construct the act of teaching through reflective thinking; 3) empirical research on preservice and inservice teachers demonstrates that preservice teachers develop their own theories of teaching from their previously held assumptions, gained knowledge from preparation programs, and their individual experiences. It also shows that inservice teachers construct teaching through their implicit knowledge and the use of strategies to negotiate problems. Implications for future studies on teachers's practices are discussed.

본 연구는 가족스트레스 이론적 모델인 Double ABCX Model과 일과 가정생활의 역할 긴장에 관한 선행연구를 기초로하여 제안된 이론적 모델을 검증하는데 목적이 있다. 이론적 모델의 검증을 통하여 일과 가정생활의 역할 stressor나 두 가지 역할의 누적으로 쌓이는 역할 긴장이 가족스트레스 이론으로 설명될 수 있는가\ulcorner 또한 매개 변수인 가족자원과 대처방안에 의해 어떻게 중재되어 삶의 질에 영향을 미치는 가를 규명하고자 한다. 미국 로스앤젤레스 지역의 한국교민 중 맞벌이 부부인 가족을 연구대상으로 선정하고 설문지법으로 남편과 부인의 자료를 분리하여 표집하였는데 본 연구에서는 153명의 부인으로부터 얻은 자료만을 분석하고자 한다. 자료는 이론적 검증에 유용한 LISREL VII 프로그램을 사용하여 분석한다. 자료의 분석결과가 처음 제안된 모델은 검증하지 못했지만 가족자원 변인과 대처방안 변인간의 상호 관계 효과를 고려하여 수정된 모델은 가족스트레스 이론으로 일과 가정생활을 병립하는데서 오는 stressor나 누적된 역할 긴장을 이해할 수 있음이 검증되었다. 모델의 검증을 통하여 맞벌이 부부가족의 부인에게는 일과 가정생활의 stressor가 누적되어 역할긴장을 증가시켰으며 이 역할긴장은 주로 가정생활의 역할 stressor에서 기인하는 것으로 나타났다. 또한 가족자원은 일과 가정 생활의 두 역할 stressor에 의해 강도를 더하는 역할 긴장을 감소시키고 삶의 질을 증가시키는 중요한 매개변수로 나타났다.
