A Research on the Proposal of U-Pavilion Adopted in Korean Residential Development
Yun, YongGib ;

Over the past two decades following the 1990s, South Korea's IT industry has developed rapidly. In keeping with this trend, the architectural and urban planning sectors have also converged with IT and achieved advancement in new directions. This evolution includes a variety of conceptual terminologies such as 'home automation', ''home network', 'smart home, and 'ubiquitous-city'. However, smart homes and U-cities simply represent a conceptual extension of home networks, and there is little real difference in the technologies involved. In particular, U-cities remain focused on infrastructure rather than on the development of specific content; consequently, they have failed to demonstrate distinctive features to clearly differentiate themselves from conventional cities. In such a context, this research aims at the proposal of a 'ubiquitous pavilion' as a component of the efforts to develop a range of architectural contents that utilize ubiquitous technologies. By grafting the pavilion, one of the most basic forms in architecture, with cutting-edge ubiquitous technologies, this paper intends to suggest a multi-purpose architectural space readily and simply available not only in newly emerging U-cities, but to conventional cities as well.
Performance of Office Workers Under Office Sounds and Various Enclosure Conditions in Open Workplaces

Effects of physical attributes of workstation enclosures on the performance of office workers with different difficult levels of office tasks and moods are presented. Performance scores in complex tasks were expected to increase with greater workstation enclosures while those in simple tasks would be the same. Mood ratings were expected to be higher in lower workstation enclosures. Performance of 102 college students on ambient office sounds (45 dBA) with office tasks were measured for 100 minutes under three different workplace enclosures: (1) four foot partitions on two sides; (2) six foot partitions on three sides; and (3) a fully enclosed workstation with eight foot partitions. The tasks were to memorize a paragraph with 130 words (complex task) and to search phone numbers (simple task). The complex task performance in the fully enclosed workstation was increased compared to that in the workstation with four foot partitions (p < 0.001) and to that in the workstation with six foot partitions (p < 0.05). However, occupants in the fully enclosed workstation with office sounds without speech generally gave higher mood ratings. It indicates that closed individual offices may offer important contributions to collaborative work as well as individual productivity. These findings would help design community revise open plan design to increase collaboration among office workers.
Ste. Genevieve Library as a Criticism of Classicism

The purpose of this paper is to reconsider and revaluate Ste. Genevieve Library designed by Henri Labrouste as a criticism of Classicism. Considered as the epitome of the early structural Rationalism the modern historian tried to focus only on the iron structure of the library. Arguably, the structural concern was one of the ideas that the architect wanted to manifest in the library. As a rebel against a view of the Acad
mie des Beaux-Art the notions of H. Labrouste were radical. He criticized an autistic Classicism with an echoing Claude Perrault's doubt about the myth of classical beauty. These radical ideas firstly showed in his report of the Grand Prix de Rome and must have been developed through several discussions for a novel: Notre-Dame de Paris by V. Hugo. 'Ceci tuera cela', one of the chapter of the novel, was generally known as the death of architecture due to the invention of the printing press around Renaissance period. We, however, consider that even though the historical background of the novel is the Gothic period the ideas, which was discussed with Labrouste, related to the death of architecture was not the architecture itself but classical architecture recomposed during Renaissance period. As the first design work the library must be reflected his ideas, which were developed, and manifested his criticism of the Classicism indirectly.
A Study on the Characteristics of Construction Wastes Generated from Demolition of Buildings in the Housing Environment Amelioration District

The amount of construction waste increased to 176,447 ton/day in 2008 from 28,400 ton/day in 2000, a 6-fold increase in just 10 years. Such dramatic increase in the waste of concrete, asphalt concrete, wood and metals was due to demolition of old buildings as well as a great number of building redevelopment projects and hurried city industrialization. Many buildings targeted for demolition today were built in line with the government policy to provide affordable housing to citizens in the shortest time possible and consequently, said buildings underwent rapid deterioration and required periodic repairs and reconstruction. Based on the above, we predict that construction waste will continue to increase for the foreseeable future. In particular, due to limited availability of suitable space to construct apartments and residential buildings in the city, old buildings are being torn down to make space for new development, further increasing construction waste. In light of that, efforts to recycle as well as reduce generated waste are urgently required.
Vibration and Buckling of Thick Plates using Isogeometric Approach
Lee, Sang Jin ; Kim, Ha Ryong ;

A study on the free vibration and linear buckling analyses of thick plates is described in this article. In order to determine the natural frequencies and buckling loads of plates, a plate element is developed by using isogeometric approach. The Non-uniform B-spline surface (NURBS) is used to represent both plate geometry and the unknown displacement field of plate. All terms required in isogeometric formulation are consistently derived by NURBS definition. The capability of the present plate element is demonstrated by using several numerical examples. From numerical results, it is found to be that the present isogeometric element can predict accurate natural frequencies and buckling loads of plates.
Improvement of a Requirement for Providing Special Boundary Element Considering Feature of Domestic High-rise Shear Walls

The reinforced concrete shear walls are being widely used in the domestic high-rise residential complex buildings. If designed by current codes, the special boundary element is needed in almost all high-rise shear wall buildings. This is because the equation for determining the provision of the special boundary element in the current codes cannot reflect the characteristics of the domestic high-rise shear walls with high axial load ratio and high proportion of elastic displacement to total displacement. In this study, a new equation to be able to reflect the characteristics is proposed. By using the equation, the special boundary element may not be necessary in certain cases so that structural engineers can relieve the burden of installing the special boundary element in every high-rise shear wall.
The Mechanical Properties of High Strength Concrete in Massive Structures

High strength concrete is being used increasingly in mass structure projects. The purpose of this study is to investigate the influence of temperature during mixing, placing and curing on the strength development, hydration products and pore structures of high strength concrete in mass structures. The experiments were conducted with two different model walls, viz.: 1.5 m and 0.3 m under typical summer and winter weather conditions. The final part of this study deal with the clarification of the relationship between the long-term strength loss and the microstructure of the high strength concrete at high temperatures. Test results indicated that high elevated temperatures in mass concrete structures significantly accelerate the strength development of concrete at the early ages, while the long-term strength development is decreased. The long-term strength loss is caused by the decomposition of ettringite and increased the total porosity and amount of small pores.
