The purpose of this study is to analyze the sustainable characteristics of London city hall designed by Norman Foster. The most important part of sustainable architecture might be the energy reduction including minimizing CO$_2$ emission but social and economical aspects of sustainability should not be neglected. London City Hall as a successful example of sustainable architecture depends its success on the harmony of social, environmental and economical aspects of sustainability. Social sustainability in London City Hall appears on appropriateness and public good in the facility. London City Hall act as a symbol of redevelopment and civic community. Environmental sustainability of London City Hall summarized as using unique building form, double skin and underground water cooling system for the purpose of energy saving. Computer modeling technology was introduced to save construction cost for economic aspect of sustainability. Rational configuration of mechanical system strengthen the durability of facility. In case of London City Hall, the function of building, site condition and architectural concept fulfill the every aspects of sustainability in architecture. Besides these conditions, Foster applied sustainability to London City Hall as active and concrete design concept to complete its design goals.

In Europe, London, Edinbergh, Copenhagen has adopted the traffic congestion charge system, and now the Stockholm City Council started the implementation of a similar system of its own. According to the Swedish National Road Administration, the system implementation starts in 2004 and will be completed by 2005, and so starting 2006, this charge system will be running as planned. Unlike the system of London, that of Stockholm charges the drivers differently depending on when to pass a control point, and not only that, the City Council has a plan to adopt the emerging RFID technology. Following is the summary of both technical and policy-wise considerations of the traffic congestion charge system in Stockholm, Sweden.

This paper presents a hybrid numerical approach, which combines a two-phase Navier-Stokes model (NS) and the fully nonlinear potential theory (FNPT), for modelling wave-structure interaction. The former governs the computational domain near the structure, where the viscous and turbulent effects are significant, and is solved by OpenFOAM/InterDyMFoam which utilising the finite volume method (FVM) with a Volume of Fluid (VOF) for the phase identification. The latter covers the rest of the domain, where the fluid may be considered as incompressible, inviscid and irrotational, and solved by using the Quasi Arbitrary Lagrangian-Eulerian finite element method (QALE-FEM). These two models are weakly coupled using a zonal (spatially hierarchical) approach. Considering the inconsistence of the solutions at the boundaries between two different sub-domains governed by two fundamentally different models, a relaxation (transitional) zone is introduced, where the velocity, pressure and surface elevations are taken as the weighted summation of the solutions by two models. In order to tackle the challenges associated and maximise the computational efficiency, further developments of the QALE-FEM have been made. These include the derivation of an arbitrary Lagrangian-Eulerian FNPT and application of a robust gradient calculation scheme for estimating the velocity. The present hybrid model is applied to the numerical simulation of a fixed horizontal cylinder subjected to a unidirectional wave with or without following current. The convergence property, the optimisation of the relaxation zone, the accuracy and the computational efficiency are discussed. Although the idea of the weakly coupling using the zonal approach is not new, the present hybrid model is the first one to couple the QALE-FEM with OpenFOAM solver and/or to be applied to numerical simulate the wave-structure interaction with presence of current.

To derive a check list of a borrowed city phenomenon, this discussion, through two cities subway OOH advertising in door, compared for convergence by segment analysis. First, discussions considered to be close to the topic of this discussion were arranged and summarized. Seoul and London were selected, and both sides of subway train doors in two cities selected, their states pictured and the images analyzed. As a result of comparison, in case of Seoul subway, the boundary between public information and commercial information(outdoor advertising) was very vague, so the borrowed city phenomenon was very generally analyzed. However, In case of London subway, its result was very contrary to that of Seoul. Eventually, Subway train doors of Seoul city as a borrowed city extracted check points of height, size, color, interval, space and permanency. Therefore in order to study serious discussion this contribution is necessity to limit thoughtless OOH advertising by these checklists in Korean cities.

Woolf s preoccupation with the interplay between gender, commercialism, and the modern city is exposed in higher relief by her feminist remapping of the city through a discourse of fl nerie, which is epitomized in her singular urban travelogues such as Street Haunting and The London Scene essays. A fanatical London-adventurer herself, she assumes the persona of the fl neuse in exploring the street of modern London and especially the public sphere of the marketplace, as represented in Oxford Street Tide. Living and working in the quarter of Bloomsbury, in close proximity to the capital s famous sites of tourism, entertainment, and mass consumption, Woolf was placed at the heart of urban spectacle. In spite of the lack of critical analysis of this high-profile writer s interest in such quotidian matters as shopping, fashion and appearance, which would be informed by a hierarchy of value within literary criticism, it seems that they are inextricably intertwined with her quest into more serious-minded topics that revolve around the twin pillars of her literary project: feminism and modernism. Her essays, in particular, suggest this point in one way or another, mirroring her extraordinary susceptibility to such concerns. For Woolf, street sauntering is synonymous with an act of creative mobility, by which she plays with the notion of shifting identities, rediscovers the urban rarities and splendors, and ultimately pins them down in her literary output. By adopting the identity of a masterly rambler/observer/explorer with an omnipotent gaze, she firmly anchors herself as an active interpreter of urban modernity and viewer of its spectacle. She thus challenges the idea of public space as a male domain, which is central to the classic androcentric discourse of loitering, spectatorship and urban modernity.

We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.

Vehicle braking in non-electrified rail systems wastes energy. Advanced flywheel technology presents a way to capture and reuse this braking energy to improve vehicle efficiency and so reduce the operating costs and environmental impact of diesel trains. This paper highlights the suitability of flywheels for rail vehicle applications, and proposes a novel mechanical transmission system to apply regenerative braking using a flywheel energy storage device. A computational model is used to illustrate the operation and potential benefits of the energy storage system.

Applying the globalization theory to the fashion phenomena which regarded the phenomena of the contemporary culture as globalization, this study had an object of looking into the globalization tendency of the fashion phenomena shown Paris, London, Milno, New York, Tokyo, and Seoul collections from 1995 to 1999. The results of this study were as follows; 1. It was the blend of romanticism that was the most common trend shown at the six world collections. 2. The works appeared at the six world collections showed the regional peculiarity under the historical background or the sociocultural influence each city had. 3. Another character appeared at the six city collections was the appearance of multi-ethnic style mixed various regional motive at a work. After all, the world fashion phenomena in the second half of 1990's could be condensed into globalization appeared homogenization, regionalization and hybridization at the same time.

A performance-based design (PBD) procedure, initially proposed for the seismic design of buildings, is tailored herein to the structural configurations commonly adopted in bridges. It aims at the efficient design of bridges for multiple performance levels (PLs), achieving control over a broad range of design parameters (i.e., strains, deformations, ductility factors) most of which are directly estimated at the design stage using advanced analysis tools (a special type of inelastic dynamic analysis). To evaluate the efficiency of the proposed design methodology, it is applied to an actual bridge that was previously designed using a different PBD method, namely displacement-based design accounting for higher mode effects, thus enabling comparison of the alternative PBD approaches. Assessment of the proposed method using nonlinear dynamic analysis for a set of spectrum-compatible motions, indicate that it results in satisfactory performance of the bridge. Comparison with the displacement-based method reveals significant cost reduction, albeit at the expense of increased computational effort.
