We construct an orthonormal basis for the Bergman space associated to a simply connected domain. We use the or-thonormal basis for the Hardy space consisting of the Szegő kernel and the Riemann mapping function and rewrite their area integrals in terms of arc length integrals using the complex Green's identity. And we make a note about the matrix of a Toeplitz operator with respect to the orthonormal basis constructed in the paper.

Let W(z) be a power series with operator coefficients such that multiplication by W(z) is contractive in C(z). The overlapping space $L(\varphi)$ of H(W) in C(z) is a Herglotz space with Herglotz function $\varphi(z)$ which satisfies $\varphi(z)+\varphi^＊(z^{-1})=2[1-W^{*}(z^{-1})W(z)]$. The identity ${}_{L(\varphi)}={-}_{H(W)}$ holds for every f(z) in $L(\varphi)$ and for every vector c.

The progress of urbanization has been accelerated by the development of machinery after the Industrial Revolution and the speed of change has been increased after the invention of computers. However, the problem of residence, the space for human life in the city, is still not complete. Ever since apartments rose as a solution for the residential problem caused by urbanization after the 1970s and now after 30 years, remodelling is preferred among the 2 choices, reconstruction and remodelling of apartments, in respect of economy and efficiency. Especially, in remodelling collective residence, construction, equipment environment, sight, etc. are considered and only after testing these various aspects can remodelling succeed. Aiming at studying the need of visual identity among many considerations in remodelling, this study investigates and analyzes the remodelling cases of domestic and overseas common residence and suggests the need of visual identity. In Korea where construction design for common residence is monotonous, expressing visual identity can be even more important. The common residence area that symbolizes its unique characteristic will elevate not only its economic value but also the psychological value of its residents.

To slove the security and efficiency problem of anonymous authentication in vehicular ad-hoc network (VANET), we adopt the bilinear pairing theory to propose an identity-based batch anonymous authentication scheme for VANET. The tamper-proof device in the on-board unit and the trusted authority jointly realize the anonymity of vehicle identity and the signature of messages, which further enhances the security of this scheme, as well as reduces the overhead of trusted authority. Batch authentication can improve the efficiency of anonymous authentication for VANET. Security and efficiency analyses demonstrate that this scheme not only satisfies such security properties as anonymity, non-forgeability and non-repudiation, but also has advantage in time and space complexity. Simulation results show that this scheme can achieve good performance in real-time VANET communication.

After 1950's, criticizing uniformity of modem architecture, a number of architectural theories and works which represet the identity of each region have appeared. However it is not a systematic theory but an attitude which approaching to design rather than new architectural trend or theory. Therefore, the thesis studied the general concept about regionalism and analyzed of the City Hall showing the regional identity. Finally this study intend to explain the detailed method of expressing regional identity created by architects by investigating the formal characteristics of regionalism and relationship with various context.

With the globalization of the film industry, ethnic minority films have been developed and studied by many scholars for their special ethnic representation. The film "Tharlo" directed by Pema Tseden carefully explores the identity anxiety of a Tibetan shepherd. Through the connection and separation between the protagonist and traditional culture, it shows a complexity of modern ethnic identity for minority people. This study explores what kind of cinematic techniques and symbolic elements the director uses to shape ordinary characters, build a narrative space, and show ethnic representation. This paper puts forward a theoretical framework combining cinematic quantitative methods with qualitative narrative and semiotic analysis, aiming to deepen our understanding of cinematic techniques and ethnic representation, and provides a new perspective and profound insights for discussing the complexity faced by ethnic minorities in contemporary films. This study finds that Tseden's "Tharlo" successfully portrays the complex transformation of Tibetan cultural identity in the context of globalization and modernization through cinematic techniques such as fixed camera positions, long take and black-and-white cinematography, combined with the use of symbolic elements like mirrors, lambs and identity cards.

Modem church architecture in korea have many problems in the shape and composition of space and design method. Many church were built without consideration of the identity of the christian religion. The characters of Ando Tadao's church architecture are using the transition space, light and the symbol. The transition space similar to the approach process using in asian temple. It make a meditative space for the church during approach to the chapel. Ando Tadao make meditative space by using self-support wall. In here, Self-supporting wall devide space as the holly space and the common space. Light is very important element in church architecture. He introduce light and shadow in the chapel more significant element. Light and shadow make the space with very dignity. Also, Ando Tadao use symbol as important element. It make the identity of christian religion. He make that as a part of structure. The well-controled symbols change the simple space to more religious place.

In the absence of the alternative public space of women in Japan, the experience of the "Bongseonhwa" was interpreted as the public domain of Japanese society as a public domain, a confession that focused on gender discrimination in the patriarchal system of Japan, Most of the enemy discourse is. These alienated discourses are the product of the efforts of women in Japan who do not want to forget about the traces and memories that can not be incorporated into the big narrative. It can not be denied that the women in the society of Japan have been excessively excluded and alienated by national ideology and patriarchal ideology. The meaning of presenting them through "Bongsinghwa" is the resistance of the minority, and it is the expression way of reconstructing and strengthening the identity of the women, and it is said to be a space of symbolic meaning. It is further clarified that it is based on a narrative that creates a new life area for coexistence with Japanese society, on the other hand, by constantly searching for the linkage with the motherland, held by women in Japan. As a result, between public social phenomena and private living space, confirmed that it conflicts with repetitive internal contradiction of controlling power and confirmed that complicated and detailed material of women living in Japan who undergo double discrimination What has been expressed over a period is considered to be a resistance expression and a will of expression of reconciliation to coexist with Japanese society. I have attempted to analyze the confessed alienated discourse of "Bongsinghwa" by classifying it as . As a result, it is confirmed that the public social phenomenon and the private life space are confronted with the repetitive internal contradictions of the power of domination, and the expression of the complex and detailed material of the discriminated women in Japan over a long period of time is a resistance to symbiosis with Japanese society And the will of the conversation.

As our lifestyles have changed due to rapid industrialization and urbanization, new social and communication problems have been caused and there have been lots of discussion on regional communication. For communities to become alternatives with realistic meanings in this changed society, considerations on social and spatial conditions are needed. Therefore, public space which works as a device of physical environment for activation of communities needs more active changes which encourages social communication. In respect to the activation of communities, the following suggestions are given: First, physical devices of a urban plaza should be arranged to support various programs presented along with consideration of human behaviors as users. Second, fundamental facilities of the plaza should accommodate various activities through connections with programs and commercial space. Third, when cultural and historical characteristics of the community are understood, the plaza can form regionality and symbolism through artistic representation. And users can form the identity of community. Fourth, transportation facilities should be separated from or coexist with areas of passengers and the plaza should have its own identity through symbolic sculptures.
