In the ancient Buddhist temple area, various metal artifacts are still excavated. Therefore, the aim of this study is to approach the characteristics of ancient architecture through ancient metal artifacts. First, metal decoration of ancient architecture appears for the purpose of structure, decoration, arson. Then, as the method of wood structure is developed, the application is separated into structural, functional and decorative purposes. In ancient times, metal decoration has reduced the role of structure, but its decorative role has expanded. Second, various metallic ornaments were used on the roof of ancient architecture. As the wooden technology developed, the metal decoration was gradually omitted while applying the curve to the roof. Third, the metal ornaments used on the roof of ancient architectures include the ridge central decoration, roof top decoration, a nine-ring decoration, gable board Ornamental Metal, corner flower decoration, eaves nail, wind bell. And subsequent research requires a terminology that can link the results of archeology and Buddhist art through excavation as a result of architecture.

Traditional Korean architecture and traditional ships maintained a close relationship with carpenters and tools because wood, the material, was common. This close relationship may have been from the time of ancient architecture and ancient ships. In previous studies, researchers proved the relationship between these two sides through historical records of traditional architecture and traditional ships. This study attempts to prove the structural association using existing remains. As a result, three structural similarities between traditional architecture and traditional ships could be found. First, the types of wood used are similar, and the tools and terms used are similar. Second, the method of distinguishing horizontal and vertical materials and the structure of wood and the method of forming wood are similar. Lastly, the ship carpenters mobilized for the construction of the palace mainly worked on long and curved materials such as the eaves and the ridge of a roof, because this was the work done when the ship was built. Therefore, it can be assumed that the roof structure they created resembles that of the ship.

Compared with other philosophers and writers who were engaged in architecture Georges Bataille was extraordinary. Because he produced anti-architectural discourse. This paper studied the Bataille's thinking with relation to architecture that used as a fundamental and privileged metaphor. Philosophy regarded as the foundation of all academic discipline needed architecture in order to show its system was durable, synthetic and hierarchical. The will to build a solid system of reasoning made philosophy to call architecture to pretend that it is structurally stable. Metaphor and representation is inevitable in philosophy. Then architectural image that supported by discourse of philosophy became a representation of sociocultural system. According to Bataille architectural representation justified existing power and belief system. With architecture Identity always represented the true and good. This kind of architectonic thinking erased the Other that allowed metaphysics and symbolic Against architecture Bataille produced writings of violation and excess corresponding to labyrinth. Labyrinth in fact made a formal structure of architecture possible to be a metaphor of symbolic system. Bataille's anti-architectural thinking paradoxically shows the importance of Architecture and give a chance to rethink the ethical aspect of architecture instead of aesthetics.

Internet network routing system is used to prevent spread and distribution of malicious data traffic. The penetration of malicious code and the function of security blocking are performed on the same course of traffic pathway. The security architecture is the concept to distinguish the architecture from the group handling with the traffic on the structure of network which is performed with the function of penetration and security. The security architecture could be different from the criterion of its realm and function, which requires the development and the application of security mechanism for every architecture. For the establishment of security architecture it is needed to show what criterion of net work should be set up. This study is based on analysis of diagnostic weakness structure in the network security architecture and research the criterion for topology factor, security architecture structure map selection, and blocking location and disinfection net. It is shown to increase the effective rate blocking the virus with the proposed method in this paper rather than the traditional network architecture.

In this study, we investigate the use of a negative stiffness tuned inerter damper system to improve the performance of a base-isolated structure. The negative stiffness tuned inerter damper system consists of a tuned inerter damper connected in parallel with a negative stiffness element. To find the optimal parameters for the base-isolated structure with negative stiffness tuned inerter damper system, we develop an optimization method based on performance criteria. The objective of the optimization is to minimize the superstructure acceleration response ratio, while ensuring that the base displacement response ratio remains below a specified target value. We evaluate the proposed method by conducting numerical analyses on an eight-story building. The structure is modeled using both a simplified 3-degree-of-freedom system and a more detailed story-by-story shear-beam model. Lastly, a comparative analysis using time history analysis is performed to compare the performance of the base-isolated structure with negative stiffness tuned inerter damper system with that of the base-isolated structure and base-isolated structure with tuned inerter damper systems. The results obtained from the comparative analysis show that the negative stiffness tuned inerter damper system outperforms the tuned inerter damper system in reducing the dynamic seismic response of the base-isolated structure. Overall, this study demonstrates that the negative stiffness tuned inerter damper system can effectively enhance the performance of base-isolated structures, providing improved seismic response reduction compared to other systems.

Unlike the extrinsic Modern Functionalist, Louis I. Kahn, a modern American architect, had been pursued intrinsic architectural nature based on historicity; The Essence of Architecture, during his lifetime. That is the reason why he is generally called as one of frontiers toward Post-Modern Architecture. However, the actual meaning of his 'The Essence of Architecture' is so vague and unclear until today, because not only his complex personal thought and career but various and subjective interpretation by so many later architects and architectural theorists. In the context, this paper attempt to reanalyze and clarify Kahn's idea of 'The Essence of Architecture' with the deep and objective view of aesthetics focused on a distinguished contemporary German philosopher, N. Hartman's idea of phenomenological relation and the stratified structure of a work of art.

In this paper multi-rate non-recursive architecture for CIC(Cascaded Integrator-Comb) decimation filters with an arbitrary factor is proposed. The CIC filters are widely used in high speed wireless communication systems since they have multiplier-less and multi-rate low-power structure. Even conventional non-recursive CIC structure is multi-rate this architecture can be structured only in case of M-th power-of-two decimation factor. This paper proposes that muli-rate non-recursive CIC architecture can be structured with an any decimation factor of product form. Power consumption of the proposed architecture is compared with that of the conventional non-recursion architecture.

The purpose of this study is to investigate the effect of the shear wall location in rigid frames on the dynamic behavior of a roof structure due to vertical and horizontal earthquake motions. The study deals with a gabled long span beam supported by two story rigid frames with shear walls. The earthquake response analysis is carried out to study the responses of the roof: vibration mode, natural period, bending moment and horizontal shear force of the bearings. The study results in the following conclusions: First, a large horizontal stiffness difference between the side frames is caused by the shear wall location, which results in a large vertical vibration of the roof and a large shear force at the side bearings. Second, in this case, the seismic design method for ordinary buildings is not useful in determining the distribution of the static equivalent loads for the seismic design of this kind of long span structures.

To study seismic performance of steel frame-bent structure, one specimen with one-tenth scale, three-bay, and five-story was tested under reversed cyclic lateral load. The entire loading process and failure mode were observed, and the seismic performance indexes including hysteretic loops, skeleton curve, ductility, load bearing capacity, drift ratio, energy dissipation capacity and stiffness degradation were analyzed. The results show that the steel frame-bent structure has good seismic performance. And the ductility and the energy dissipation capacity were good, the hysteresis loops were in spindle shape, which shape were full and had larger area. The ultimate elastic-plastic drift ratio is larger than the limit value specified by seismic code, showing the high capacity of collapse resistance. It can be helpful to design this kind of structure in high-risk seismic zone.

In this paper, we propose a programmable 16 bit DSP architecture using FIFO instruction memory. With this DSP architecture, System structure, BUS structure, instruction set ant and an assembler for system test are developed. The characteristic of this structure is that it simply fetches instructions not from RAM but from FIFO using shift operations. Accordingly, System can be designed regardless of RAM access time. One cycle is enough to execute an instruction, if instruction pipeline is operated. Another merit of this structure is that we can obtain the same effect as instruction pipelining without constructing a complex pipelined controller by decreasing the pipeline number.
