In architectural planning, previous cases of similar spatial program provide important data for architectural design. Case-based reasoning (CBR) paradigm in the field of architectural design is closely related to the designing behavior of a planner who makes use of similar architectural designs and spatial programs in the past. In CBR, spatial graph can be constituted with most fundamental data, which can provide a method of searching spatial program by using visual graphs. This study developed a system for CBR that can analyze the similarity through graph comparison and search for buildings. This is an integrated system that is able to compare space similarity of different buildings and analyze their types, in addition to the analysis on a space within a single structure.

An efficient demolition process requires the optimum method selection considering stability, economic feasibility, environment, and workability. In reality the construction cost and period are priority concerns, and safe construction methods are neglected. In addition, the choosing demolition method is often determined subjectively by experienced field engineers. This research paper presents a multi-criteria decision-making method using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to select the optimum demolition method. Three experienced demolition engineers' opinions were used to develop the TOPSIS model. The case study showed that the preferences of ten attribute measurements for demolition method selection. Authors suggested the most preferable demolition method for the case study project.

The construction industry highly depends on each specialized manager which is essential to successful project. However, a new employee, who has just graduated from architectural engineering college, is requested additional education for 1~2 years such as On-the-Job-Training (O.J.T) to perform his/her professional job in construction site. It is wasteful for both construction company and the employee in terms of time and cost. The purpose of this paper is to investigate the required abilities and analyze the gap of demanded abilities between field managers and students. To collect data for analysis, questionnaire which uses Likert Scale has been performed to both parts. As a result, the analysis show that the graduate's abilities related to field experience get especially low degrees in compare with non-field experience factors. These results will contribute architectural engineering education in college to make more realized.

In apartment housing construction, window frame installation work, which is conducted after the structural framework, is very important, because its completion time directly affects the starting time of successive interior finishing works, as well as the overall construction period. Construction delays in interior finishing works might occur due to problems inherent to the conventional window frame installation method, such as the poor verticality of window frames, and the water leakage around them. The primary objective of this study is to analyze the problems of a 'Gangform integrated PVC window frame pre-installation method' based on its pilot test results. Next, this study proposes an improved conceptual model that enables the end users to enhance the field applicability of this method in terms of productivity, time, and cost. The field applicability of the proposed 'Gangform integrated PVC window frame pre-installation method' was also verified through a survey.

Tornadic wind flow is inherently turbulent. A turbulent wind flow is characterized by fluctuation of the velocity in the flow field with time, and it is a dynamic process that consists of eddy formation, eddy transportation, and eddy dissipation due to viscosity. Properly modeling turbulence significantly increases the accuracy of numerical simulations. The lack of a clear and detailed comparison between turbulence models used in tornadic wind flows and their effects on tornado induced pressure demonstrates a significant research gap. To bridge this research gap, in this study, two representative turbulence modeling approaches are applied in simulating real-world tornadoes to investigate how the selection of turbulence models affects the simulated tornadic wind flow and the induced pressure on structural surface. To be specific, LES with Smagorinsky-Lilly Subgrid and k-ω are chosen to simulate the 3D full-scale tornado and the tornado-structure interaction with a building present in the computational domain. To investigate the influence of turbulence modeling, comparisons are made of velocity field and pressure field of the simulated wind field and of the pressure distribution on building surface between the cases with different turbulence modeling.

In recent years, the number of female workers pursuing careers in the construction engineering and management field has increased, despite the fact that the job positions have been traditionally considered as retaining job functions and/or qualities that are more appropriate to male than female. This may be attributed to the fact that the positions also require delicate and/or detail-oriented job functions, which can be successfully performed by female. It is important for project participants to understand the working conditions for female field managers by analyzing their job performance. This study collects expert opinions regarding female's managerial performance on job site. Survey questionnaires were administered to two focus groups, male and female field managers who work for general contractors. This study contributes to encouraging female's social and economic involvement by investigating the challenges they face in the workplace, and provides measures to respond to such challenges.

This study is an attempt to prove a relationship between Le Corbusier's utopian attitude towards nature and architectural ideology and ideology by a form of inquiry into sociological interests. That is to find out contradictions and limitations in Le Corbusier's architectural world, namely particularity of his ideology by exploring the base entangled with special interests in the society up until formation of his architectural language. A process of this study is by; 1. Examining of background which affected Le Corbusier's attitude towards nature until the nature became his architectural language; 2. An analysis of Le Corbusier's architectural works. That is, this study's main interest is on formation of Le Corbusier's architectural language by his attitude towards nature which present in residential field especially focused on Villa Meyer and Villa Savoye, two best examples of his villa. 3. This study have a goal to investigate that utopian and ideological conception in architecture of Le Corbusier have a dialectic relationship between them. This goal can be achieved by observing in what ways Le Corbusier's utopian attitude towards nature is expressed in residential architectural language and researching into his inconsistent architectural ideology derived from applying architectural language present in villa to pre-fabricated apartment houses.

Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.

Companies want universities to produce graduates with creativity and problem-solving skills, and for this reason universities have extended engineering design education, including in the field of architectural engineering. This paper investigates an engineering design class in the Department of Architectural Engineering, J University. The class was taught in 2010 and 2011using an Action Learning (AL) teaching-learning strategy. The students responded that the level of participation and satisfaction was high in the Action Learning classes, and role allocation or responsibility and communication of the project teams were very effective. But it was also found that as Action Learning is such a new method for students of engineering design, an orientation session that describes what to do and what to prepare should be given before the class starts.

We need to have a universal system for the landscape architectural profession at the national level which focuses on public facilities from an aesthetic point of view and emphasizes the landscape architectural identity and traditional idiosyncrasy in Korea society. There should be established independent official positions in governmental systems in order to work practically in the field of landscape architecture concerned with ecological and environmental stability. Professionals should be acquired and diversity maintained for administrative efficiency, so that the governmental official position could create practical need and a theoretical approach to the human needs for environmental quality and ecological stability. In order to pursue the public good, we need to establish a new community and promote a global spirit, which include an ecologically stable environment developed through professional landscape architectural harmonization. The landscape architectural profession requires a new community spirit suitable to modern society, so that the Korean people continue a tradition of cooperative control of the common wealth and the labor market.
