This paper proposes a group key management protocol for a secure of all the multicast user in PIM-SM multicast group communication. With prosed architect, subgroups for multicast secure group management will be divided by RP (Rendezvous-Point) unit and each RP has a subgroup manager. Each subgroup manager gives a secure key to it's own transmitter md the transmitter compress the data with it's own secure key from the subgroup manager. Before the transmitter send the data to receiver, the transmitter prepare to encrypt a user's service by sending a encryption key to the receiver though the secure channel, after choking the user's validity through the secure channel. As the transmitter sending a data after then, the architecture is designed that the receiver will decode the received data with the transmitter's group key. As a result, the transmitting time is shortened because there is no need to data translation by group key on data sending and the data transmition is possible without new key distribution at path change to SPT (Shortest Path Tree) of the router characteristic. Additionally, the whole architecture size is samller than the other multicast secure architecture by using the conventional PIM-SIM routing structure without any additional equipment.

Beatrix Farrand was America's first female landscape architect and Dumbarton Oaks in Washington, D.C., USA site of her best known garden design. The purpose of this study is to identify characteristics of the American Neoclassical tendencies in the early 1900s and Farrand's style through an analysis of Dumbarton Oaks. The results of analysis indicated that although Dumbarton Oaks was influenced by many European classic gardens, the garden has the unique style which reflects regional contexts and culture based on the philosophy of arts and crafts movement, The major characteristics of the late Neoclassical style in America can be summarized as follows. First, A series of terraced gardens were connected by paths and stairways and natural terrain was preserved as much as possible. Second, the formal and informal style coexist and the symmetric and asymmetric forms are well-balanced throughout the garden. Third, selection of plant materials and planting methods, influenced by both classical gardens and the Arts and Crafts style in UK, are in harmony with the space configuration and shape.

The Second Namsan Tunnel required renovation. The landscape design was conducted as part of the comprehensive programs for renovation. The landscape design covered site analysis, design development, a working drawing and a maintenance plan. In May of 2001, the Second Namsan Tunnel was renovated and reopened to traffic. The tunnel was recreated as a new type of tunnel with function and beauty. The entrance and retaining wall of the tunnel has public character. Users are greatly affected by the entrance and retaining walls along roads. The landscape architect had to find new materials and methods to improve the environment and to combine artwork with the entrance and walls of the tunnel. The surface of the tunnel entrance and retaining walls are artistically treated with ceramic tiles and paint. Various regional characteristics and cultural meaning are symbolically expressed. Or the tunnel entrance from the Joong-gu side, entitled "Glory of the Future", the hibiscus symbolizes the bright and glorious future of Korea. On the retaining walls, entitled "Hope", the promising Joong-gu is symbolized through image of Korean magpies, mountains, rocks, roses, winds and nature. As for the tunnel entrance from the Yongsan-gu side, entitled "Vivid Spirit", pine trees symbolize the Koreans′strong will and an enterprising spirit. On the retaining walls, entitled "Lively Motions", Yongsan-gu is symbolized through image of pigeons, mountains, rocks, roses, winds and clear skys. The entrance and retaining wall of the Second Namsan Tunnel, whose surfaces are treated with tiles and paint with artistic value, would create an atmosphere using large-scale wall paintings. In this artwork, users would perceive a unique sense of place through the symbolic images of the vertical planes of the tunnel.

This study concentrates on a new idea that is formulated as a creative spatialization in contemporary architecture. Suggested from the classical baroque, this study tries to open the actual sense area of 'the baroque' by analysing the architectural ideas of wrenching and folding by Frank O. Gehry. The redefined 'new baroque' operates in the chain of the transformable and flexible images that must be recognized as 'the real' in the sense of 'the most empirical' and are vulnerable to dispersal. The typical instrument of Gehry's 'new baroque architecture' is the enclosing of the space and its folding. This idea meet the theoretical gravitation field of the philosophy of Deleuze, in which the reconstituted baroque conception means the tension between the folds, on expansion and contraction of which the variable space is dependent. Through the general principle of 'the new baroque', a free dispersal of power, to architect is offered the possibility, to make the real world intimate to the real life and to produce from there a vivid new space, and to enjoyer and viewer the possibility, to perceive the operating power in and around oneself.

The structural aesthetics of architecture are becoming an inspirational source for many fashion designers and have been reborn in structural fashion. This study planned to analyze the method of expression of structural aesthetics expressed in modern structural fashion design and the construction method to maximize such an effect on the basis of the construction characteristic of Santiago Calatrava as the representative architect of the structural aesthetic. According to the study, the structural aesthetics expressed in modern structural fashion design are as follows: 1) The symbolical formative aesthetic expressed by symbolical inference and analyzation; 2) the dynamic beauty of physic expressed by visual emphasis and dynamics; and 3) the asymmetric beauty of symmetry expressed by metastasis toward the boundary between balance and imbalance. In addition, to maximize structural aesthetics, we used repetition and a progressive technique based on rhythm, asymmetry, and incision-based variances, such as balance, polygon flux, and inference, and analyzation-based distortion as the structuring principle. The following expression methods for maximizing structural aesthetics were found: 1) symbolical and structural exaggeration of appearance; 2) detail technique expansion and material property diversification; and 3) the three-dimensional transformation of structure and shell expression. Structural fashion design was found to have maximized structural aesthetics by using such expression methods to secure artistic esthetics, destroy existing shapes and patterns, and create unique shapes.

1) The structural system of "Hwaeomgyeong" has its core in the fact it deals with certain themes repeatedly on the basis of "Sipjipum" as a system of discipline.( The key of Euisang's ideas lay in referring to the whole "Hwaeomgyeong" as Beopseong and expressing it with the term, 'Haeng'. Here 'Haeng' is a system of discipline based on "Sipjipum". This indicates that "Hwaeomgyeong" can be fully represented just by "Sipjipum" because the twos are structurally similar) (1) In "Sipjipum", a summary of "Hwaeomgyeong" is contained. Thus descriptions of "Sipjipum" may be like those of "Hwaeomgyeong". (2) "Hwaeomgyeong" had a three-dimensional spatial structure which corresponds with the Heaven of Yok Gye Yuk Cheon and the Earth, when associated with places of preaching Buddhist sermons. 2) This researcher investigated stone platforms of the Buseoksa Temple with references to "Hwaeomgyeong" and "Sipjipum". 1) All the platforms, whether their building is still remained on them or not, comply better with implications of "Sipjipum". 2) Different heights of the stone platforms and the axial refraction of the platforms brought by their shape changes all imply variations in discipline levels descrided in "Sipjipum", in terms of form and symbolic implication. Sites which mainly compose the stone platforms also comply with descriptions contained in "Hwaeomgyeong" regarding the place, frequency and contents of preaching Buddhist sermons. In conclusion, the outside of the Buseoksa Temple is composed of architectural spaces for which contents of "Hwaeomgyeong" and "Sipjipum" and the frequency and place of preaching Buddhist sermons are fully considered and comprehended.

The Gallery of Casa del Agua in Jeju Island was demolished by Jeju local government on March 6 in the last year. In the meanwhile, a lot of people including the architectural field had denied the demolition. Regardless of sustained efforts in order that the building could be preserved as a work, Jeju government ended up with demolishing the gallery. The Gallery of Casa del Agua was a temporary building constructed as a model house of Casa del Agua. As the remaining period of the temporary building had passed, it was on the verge of demolition by Jeju government. Casa del Agua is 'dwelling of water' in Korean, and the building was the last posthumous work of Mexican architect Ricardo Legorreta. Knowing from the expression of 'dwelling of water', this house is a dwelling work of him. Through this work, his architecture languages that he had pursued contained in dwelling could be looked into. This study examined the background and course of demolition of the Gallery of Casa del Agua, 'dwelling of water' and arranged problems in the course of demolition. Then, the fact that the Gallery of Casa del Agua as an architecture work of Ricardo Legorreta included his architecture languageswas analyzed. For this, his universalarchitecture languages were examined and how the architecture languages were applied to the Gallery of Casa del Agua was analyzed. As a result, it could be known that languages of composition and languages of emotion consistently shown in his works were represented in the Gallery of Casa del Agua.

This study focuses on the social problems such as aging and nuclear family in our society, and aims at carrying out basic research for the new residential culture plan corresponding to this socail phenomenons. The subject of this study is $Unit{\acute{e}}$ d'Habitation in Marseille, a French public collective housing designed by architect Le Corbusier. Among the important national ideologies that the French government has built through the long history and cultural growth, the theme of 'Residence' is not only a residence but a foundation of citizen welfare. In this context, the value of $Unit{\acute{e}}$ d'Habitation as common collective housing is very high because it presents the spirit of citizen welfare pursued by the country as residential community where various generations of households can coexist together. It is expected that the study on residential community, which is the subject of this study, will positively influence the presentation of a new residential culture for various subdivided generations of our society.

Recently, Korean Traditional House is being reconsidered as a alternative and eco-friendly residential housing. With these flows, government and industry actively studies the modernization and industrialization of Korean Traditional House. Apply for BIM as a way of modernization and industrialization of Korean Traditional House, research has been actively conducted. Korean Traditional House is building that is assembled by individual Component Therefore it is very useful for modernization of the Korean Traditional House to design Korean Traditional House With BIM. Which is the management technology that produces and distributes information of the architecture. But compared with the effect, the use of BIM is sluggish in the construction. Therefore, In this study after surveying about lowly using BIM on point of AEC(Architect-Engineer-Contract), the result is analyzed with AHP(Analytic Hierarchy Process). So the aim of this study is to offer the base to find the solution of the Affecting factors about lowly using BIM.
