The purpose of this study is to find out the architectural device for two places to be perceived as having distinct characteristics from each other. A residence of Yi Dynasty is selected as the object appropriate for this purpose and analyzed accordingly. The result of the analysis can be presented on two demensionis one is that of the concrete form and the other is that of the abstract meaning generated by the form. It is meaningless to employ the form of the architecture of the past in today's architecture. The language of the architecture of the past must be reinterpreted into that of tody. This means understanding and expressing the meaning of the architecture of the past, using the form and materials available today. Without limiting its scope to figuring out "the architectural device for giving destinction" on the formal demension. this study tries to clarify the meaning generated by the form, on which its significance can be said to lie.

Wireless sensor networks are subject to highly heterogeneous system requirements in terms of their functionality and performance due to their broad application areas. Though the heterogeneity hinders the opportunity of developing a single universal platform for sensor networks, efforts to provide uniform, inter-operable and scalable ones for sensor networks are still essential for the growth of the industry as well as their technological advance. As a part of our work to develop such a robust platform, this paper presents the software architecture for sensor nodes with focus on our sensor node operating system and its configuration methodology. Addressing principle issues in its design space which includes programming, execution, task scheduling and software layer models, our architecture is highly reconfigurable with respect to system resources and functional requirements and also highly efficient in supporting multi-threading under small system resources.

In the previous work, we dealt with a traffic analysis of network-based control system and its architecture using the CAN protocol. It is difficult to determine an optimal network architecture for a specific system. In this paper, we propose the architecture of network-based control system applicable to a specific AGV system with manipulator arms. We define the fixed number of periodic messages to be occurred in this system. In the proposed system architecture, we analyse its traffic for the real-time communication of all messages, determine the optimal sampling period of an analog sensor to be satisfied with the required specification and the number of possible sensors to be added through simulation.

This paper presents an architecture for distributed control systems and its underlying methodological framework. Ideas and concepts of distributed systems, artificial intelligence, and soft computing are merged into a unique architecture to provide cooperation, flexibility, and adaptability required by knowledge processing in intelligent control systems. The distinguished features of the architecture include a local problem solving capability to handle the specific requirements of each part of the system, an evolutionary case-based mechanism to improve performance and optimize controls, the use of linguistic variables as means for information aggregation, and fuzzy set theory to provide local control. A distributed traffic control system application is discussed to provide the details of the architecture, and to emphasize its usefulness. The performance of the distributed control system is compared with conventional control approaches under a variety of traffic situations.

In this paper, we propose a now architecture for hardware implementation of digital neural network. By adopting flexible ladder-style bus and internal connection network into traditional SIMD-type digital neural network architecture, the proposed architecture enables fast processing that is based on parallelism, while does not abandon the flexibility and extensibility of the traditional approach. In the proposed architecture, users can change the network topology by setting configuration registers. Such reconfigurability on hardware allows enough usability like software simulation. We implement the proposed design on real FPGA, and configure the chip to multi-layer perceptron with back propagation for alphabet recognition problem. Performance comparison with its software counterpart shows its value in the aspect of performance and flexibility.

Contradictions often occur between the process of urban modernization and protection of history and culture, which have become the topics of current studies. The development of a city has its past, present and future while history and culture have their continued process. Culture is the sediment of history, left among buildings and merged in life. Exerting a subtle influence on the construction of a city and behaviors of citizens, culture is very important to the urban construction and is also the soul of a city and its buildings. Culture is closely bound up with inhabitants' life and the key to protect well the cultural features is to protect well historical and cultural venues. Qushuiyuan Garden is a venue for local folklore activities. The programming holds that folklore, historical and humane sceneries should be protected and left to our coming generations.

A new 5-MW floating offshore wind turbine moored by a spring-tensioned-leg was proposed for installation in about 50m water depth. Its substructure is a platform of the inverted conical cylinder type with massive ballast weight plate at the bottom. A 1:128 scale model was built for the preliminary engineering development. The model tests in waves and wind were carried out to estimate motion characteristics of this platform in the Ocean Engineering Wide Tank of the University of Ulsan. Its motions were measured and the RAOs were compared. The proposed floating offshore wind turbine showed a good stability and decent responses in waves, wind and operation of the wind turbine.

In today's turbulent business landscape, a firm's ability to explore new IT capabilities and exploit current ones is essential for enabling organizational agility and achieving high organizational performance. We propose IT exploration and exploitation as two critical organizational learning processes that are essential for gaining and sustaining competitive advantages. However, it remains unclear how the emerging cloud-based IT architecture affects an organization's ability to explore and exploit its IT capabilities. We conceptualize modularity and virtuality as two critical dimensions of emerging cloud-based IT architecture and investigate how they affect IT exploration and exploitation. We test our hypotheses using data obtained from our field survey of IT managers. We find that modularity is positively associated with both exploration and exploitation whereas virtuality is positively associated with exploration, but not with exploitation. We also find that the effect of modularity on exploitation is stronger than its effect on exploration.

In Korea, the function of Jeong(亭), Jeongja(亭子), and Nujeong(樓亭) architecture is essentially rest. However, in China, where the name Jeong was first coined and used, Jeong was not only used as a place of rest, but also for a variety of functions depending on the time and region, such as building units for guard posts, policing, and mail delivery. But why is it that in Korea, Jeong is primarily perceived and used as place of rest? Starting from this question, this article examines the historical process of the emergence of Jeong and its changing functions, focusing on the official history of China, and then examines the perception of Jeong in Korea through its connection to the dominant function of Jeong in China during the period of Jeong's emergence in Korean literature. This will help us to fundamentally understand the differences between Jeong architecture in Korea and Jeong architecture in China, and to further clarify the historical significance of the types of Jeongja and Nujeong architecture in Korea.

Enterprise Architecture and its management focuses on the integration of business processes and IT infrastructure, and have received considerable attention from the academic and the practice audience. Despite this attention, some lacuna can be observed that questions some of the fundamental pillars of the domain. The current business environment demands in the response to digitalization add to further challenges which call for the need to reconceptualise enterprise architecture to be relevant to the emerging context. We respond to this call by presenting a comprehensive review of the literature concerning enterprise architecture and management to facilitate future work. Our review revealed various facets related to enterprise architecture and enterprise architecture management which we present and discuss here. Further, we also chart out possible areas of future explorations. By doing so, this research lays a foundation for continuing inquiry on enterprise architecture and management, contributing to new knowledge for the field.
