Urban is made over a long period of time. In the process, architecture involves design characteristics of age and place. In the case of modem western style architecture, just depend on the economic logic, they are continuously threatened during urban changes. Therefore, the purpose of this paper is to recognize modern western style architecture as valuable things, which represents color of urban, and to seek how it can be reused. This is a process in order to find a new method for conservation and reuse of modern western style architecture. The result are as followings. Modern western style architecture must be recognized as resource, which expresses identity of urban, and found a method for conservation and reuse of facade at least. So we need to search design characteristics of facade. It has been analyzed that assigned modem western style architecture in seoul can be divided into 6 groups. Each group has individual characteristics of facade expression, which is 'dormer', 'vent', 'balustrade', 'cornice', 'dome', 'tower', etc in top part, and 'the shape of window and door', 'the element of ornament', 'finish', etc in middle part.

Generally, the shipbuilding industry has finite resources and limited workspace. Due to finite resources, limited workspace and state of block preparation, erection process in shipbuilding industry is frequently delayed than erection process scheduling which is planned at long-term plan stage. In this study, considering variability of block reserve ratio, the degree of delay in real erection process is measured and compared to scheduling which is planned at long-term plan stage in shipbuilding industry including finite capacity and variative lead time. Also, the erection process scheduling which has minimum lead time can be checked through simulation. The results of this study could be improved the accuracy of erection process scheduling by checking the main event compliance ratio by block reserve ratio and calculating the optimum erection pitch for the main event compliance.

In the design process of modern architecture, diagrams are most commonly used as tools of explanation and creation. Many architects use diagrams in the process of explaining or creating their own works, and the concept of programs and diagrams expressing them are accepted by audiences as part of creative work in the process of actual architectural design beyond the role of a medium. Therefore, the purpose of this study is to analyze the various uses of architects through diagrams in the construction process and the operation process of diagrams applied in the design process by defining diagrams by era as a tool to show the process of building space over the past 30 years.

Since the past, an attempt of figuration which is for movement, time and force has existed constantly. A process of representative from expressed on the movement, time and force creates events, and the process through the events expresses the idea of a simulacre. Furthermore, Architectural works for potentiality to give a demonstration are in common with hybrid characteristics, and have lasting creation of flux architecture. Ignoring the gravity of the floating figuration, so it appears unrealistic hyperphysical virtual space that easily could make the life of creation. For this reason, the form generation based on the digital design method is expressed the important method. In conclusion, actualizing the virtual is the suitable way for 'devenir architecture' based upon the Deleuze Guattari's idea of 'simulacre' and creating the from generation on the contemporary digital architecture design in a similar way.

This Paper examines theoretical terrains and design strategies of landscape urbanism which is an emerging hybrid field at the intersection of architecture, landscape architecture, and urbanism. Landscape urbanism offers alternative approaches for theory, education, and practice in contemporary landscape architecture. It views the emergent urban complex sites-post-industrial sites, landfill, brownfield, urban void, etc., not as a weakness, but as a strength. Landscape urbanism poses an understanding of landscape as an element of urban infrastructure. In this sense, the landscape is seen in the context of contemporary urban development and public works. As a complex amalgam, landscape urbanism is more than a design style it is an ethos, an attitude, a way of thinking and acting. We can chart the main characteristics of landscape urbanism such as horizontality and surface, infrastructure, process, technique, and ecology. Multilayered examples of landscape urbanism can be seen in several experimental practices such as worts of Rem Koolhaas, MVRDV, Adriaan Geuze/West 8, James Comer, etc. It is possible to summarize the productive strategies for landscape urbanism as follows : thickening, folding, new materials, nonprogrammed use, impermanence, and movement.

This paper proposes a generic security architecture designed for a multidomain and multiservice network based on programmable networks. The multiservice network allows users of an IP network to run programmable services using programmable nodes located in the architecture of the network. The programmable nodes execute codes to process active packets, which can carry user data and control information. The multiservice network model defined here considers the more pragmatic trends in programmable networks. In this scenario, new security risks that do not appear in traditional IP networks become visible. These new risks are as a result of the execution of code in the programmable nodes and the processing of the active packets. The proposed security architecture is based on symmetric cryptography in the critical process, combined with an efficient manner of distributing the symmetric keys. Another important contribution has been to scale the security architecture to a multidomain scenario in a single and efficient way.

Two High Tensile Strength Steel (EH47) plates with thickness of 70 mm were butt-welded together by multi-pass Submerged Arc Welding (SAW), also the hardness and welding residual stress were investigated experimentally. Based on Thermal-Elastic-Plastic Finite Element (TEP FE) computation, the thermal cycles during entire welding process were obtained, and the HAZ hardness of multi-pass butt welded joint was computed by the hardenability algorithm with considering microstructure evolution. Good agreement of HAZ hardness between the measurement and computational result is observed. The evolution of each phase was drawn to clarify the influence mechanism of thermal cycle on HAZ hardness. Welding residual stress was predicted with considering mechanical response, which was dominantly determined by last cap welds through analyzing its formation process.

MANPro-based control is a novel control paradigm aimed at intelligent manufacturing systems on the basis of mobile agent-based negotiation process (MANPro). MANPro is a negotiation mechanism based on the agent-based control architecture and, especially, it adapts a mobile agent system called N-agent for the negotiation process. N-agent travels around the network of distributed manufacturing systems to acquire information, and it makes a decision for system control according to the obtained information. MANPro includes communication architecture and information architecture for intelligent shop floor control. MANPro also considers the following issues: (1) negotiation mechanism, (2) single-agent internal strategic policies, and (3) information model. Communication architecture concerns the first issue of the negotiation mechanism. It provides information exchanging mechanism with functional modules. In specific, N-agent is equipped with an intelligent reasoning engine with a built-in knowledge base. This reasoning engine is closely related to the single-agent internal strategic policies of the second issue. Finally, ontology-based information architecture addresses information models and provides a framework for information modeling on negotiation. In this paper, these three issues are addressed in detail and a framework of MANPro-based control is also proposed.

Product Line Engineering (PLE) has been widely accepted as a representative software reuse methodology by using core assets. Product line architecture (PLA) is a key element of core assets. However, current research works on designing PLA do not provide sufficient and detailed guidelines of defining PLA and reflecting variability in the architecture. In this paper, we present a reference model of PLA and propose a process to design PLA with detailed instructions. Especially architectural variability is codified by describing decision model depending variation points and traced through PLA activities. The proposed process would make it feasible to apply PLE to practice areas.
