Considering Materiality of Glass as a System with Interactive Layers
Kim, Sung-wook ; Kim, Do-sik ;
Architectural research, volume 11, issue 2, 2009, Pages 1~8
In contemporary architecture, glass is being used less as a single piece for the exterior envelope, due to a variety of influences such as increased performance regulations, the market environment and technical developments. An architectural exterior wall today is usually installed as a 'ystem' wall, not as a single plane glass wall. That brings up the necessity to question the appropriateness of the materiality of an individual piece of glass for the exterior envelope in urban settings. Therefore, in many cases it is appropriate to examine materiality of glass as a system. A new examination of materiality can be carried out by analyzing the interactions between layers that constitute a system. This paper examines the experimental use of glass systems in contemporary architecture, and analyzes them to interpret the relationship between the layers of each system in order to establish the diversified materiality of glass in contemporary architecture.
Cross-Current Contribution : A Study on East Asian Influence on Modern Architecture in Europe
Kim, Hyon-Sob ;
Architectural research, volume 11, issue 2, 2009, Pages 9~18
This research started from the premise that East Asia - China, Korea and Japan - played a remarkable role in the development of modern architecture. In this study, attention is paid to the lack of a synthetic research about the influence of East Asia on European modernism as a counterpart to its influence on American modernism. Thus, the intention of this paper is to construct an integrated discourse on the East Asian contribution to European modern architecture. By analyzing recently published/presented articles on the related subjects, this study suggests how European modernists encountered the East, what attracted them to the East, and how they applied East Asian aesthetics in their designs. While a number of architects adopted East Asian formal elements directly, at times superficially, others extracted the underlying principles. As a whole, this analysis offers insights at several levels. First, it provides a balance to the view of the East Asian influence on modern architecture by providing an investigation into its influence on European modernism as a counterpart to its influence on American modernism. Second, the multi-faceted nature of modern architecture is further illuminated in this study. Third, an important example of "positive-Orientalism" is provided, which contrasts with the rather negative image implied by E. Said's 'Orientalism'. In conclusion, this paper provides a critical assessment of the fundamental motive of European modernists' adoption of East Asian aesthetics.
The Effect of Rebirthing Technique on GA-based Size Optimization

The effect of rebirthing technique on the genetic algorithm (GA)-based size optimization is investigated. The GA mimics the principles of nature and it can gradually improve structural design through biological operations such as fitness, selection, crossover and mutation. However, premature optimum has been often detected in the generic GA with continuous design variable. Since then, the so-called rebirthing technique has been proposed to avoid this problem. However, the performance of the rebirthing technique has not been reported. Therefore, the size optimizations of spatial structures are tackled to investigate the performance of the rebirthing technique on the generic GA. From numerical results, it is well proved that the rebirthing technique is very effective to produce the optimum values regardless of the values of parameters used in the GA operations.

The purpose of this study is to investigate the problem of crack repair materials and methods in existing concrete structure and to propose the effective injection method on crack repair by packer type. The result of this study is as follows. It is investigated that the crack width in the inner matrix of concrete structure is decreased about 30-40% than that in the surface of the concrete structure. Also it is showed that the possibility which could be monolithic with injection part became higher if the injection part is installed near to surface of concrete on the punching method to vertical direction against crack area. The injection of repair material can be poured smoothly under about
pressure on the condition that cracks are monolithic with injection part without dust by drill. The method which is effective injection for a repair material is the punching method in compliance with coredrill. But, the research continuously is necessary about minimum injection pressure.
A Model of Risk Management Plan in the Development Phase of Urban Regeneration Project

Architectural research, volume 11, issue 2, 2009, Pages 35~42
Recently, intensive urban redevelopment concentrated on new towns has reduced the number of settled population, and weakened various functions such as commercial, culture, education and welfare in old towns, and made the stagnation and declination of the entire or some parts of old towns. Urban regeneration project means renewing cities' functions in terms of physical, environmental, social, cultural, industrial and economic aspects or revitalizing the existing functions through improvement project in the entire or part of a city, which is now drawing keen attention from the public. However, urban regeneration project is huge in scale, needs long construction period and various complex facilities, and also characterized by complicated relations with many stakeholders. Due to such characteristics, there are many risks in the project. Therefore, systematic risk management is absolutely necessary to efficiently manage various risk factors inherent in urban regeneration project. The purpose of this research proposes a basic model to establish risk management plan and work process in order to help project participants to perform risk management more systematically and rationally in the development phase of urban regeneration project.
Time-Cost Trade-Off by Lead-Time Adjustment in the PDM Network
Kim, Seon-Gyoo ;
Architectural research, volume 11, issue 2, 2009, Pages 43~49
Since the late 1980s, the schedule technique applied to the construction industry around the world has rapidly changed from the traditional ADM (Arrow Diagramming Method) to the PDM (Precedence Diagramming Method) technique. The main reason for this change is to overcome the limits and inconveniences of the traditional ADM technique. The time-cost trade-off is one of the core scheduling techniques to establish the best optimized combination plan in terms of a relationship between the cost and schedule. However, most of the schedule-related textbooks and research papers have discussed and proposed applications of a time-cost trade-off technique based only on the Finish to Start relationship. Therefore, there are almost no consideration and discussion of problems or restrictions that emerge when the time-cost trade-off technique is applied to the PDM network that has overlapping relationships. This paper proposes the lead-time adjustment method as a methodology for overcoming some restrictions that are encountered when the time-cost trade-off technique is applied to the overlapping relationships of the PDM network.
