Gesamtkunstwerk in Design: Interdisciplinary Design and Pedagogy
Lee, Youngjin ;
Architectural research, volume 15, issue 3, 2013, Pages 111~121
DOI : 10.5659/AIKAR.2013.15.3.111
This paper examines the interdisciplinary practice within design realms including urban planning, architecture, landscape architecture and interior design. It discusses the pedagogical approaches at design schools to foster designers capable of design challenge with interdisciplinary skills. As the complexity of contemporary multicultural society increasingly requires a higher level of expertise in professional service, no individual designer can be expert in all fragmented expertise across the whole design and associated engineering areas. A designer, therefore, should rely on the expertise of other practitioners in areas where he or she doesn`t possess proficiency and educational background. From this sense the need of interdisciplinary approaches across diverse range of design and engineering through the collaboration is rising. Historically most of discussion made on interdisciplinary approaches is limited to collaboration between architecture and supporting engineering. This paper focuses on the collaboration with design realms. Three case studies done in an interdisciplinary firm are explored, focusing on design process that is non-linear and complementary. Finally the integrative pedagogical approaches to provide students with more exposure to allied disciplines are navigated with exemplary student work from interdisciplinary design studio.
Customization and Autonomy : Characteristics of the Ideal Design Studio Instructor in Design Education
Cho, Ji Young ;

DOI : 10.5659/AIKAR.2013.15.3.123
Design studio is a unique type of course in architecture and interior design education, in which learning is based on student-instructor interaction and learning by doing; yet little research has been conducted on student perceptions of the ideal design studio instructor. The purpose of this paper was to identify characteristics of the ideal studio instructor from student perspectives. Three award-winning design studio instructors` studio activities were observed, and the three instructors and their 40 students were interviewed. As a result, characteristics in four categories were identified. The author argues that providing customized feedback and allowing student autonomy are the two distinct characteristics that students value in design studio as compared to students in other fields or type of courses. The findings provide valuable insights to design educators who would like to strengthen their teaching studios by listening to student voices.
Changes in Urban Planning Policies and Urban Morphologies in Seoul, 1960s to 2000s
Kim, Sung Hong ;

The purpose of this paper is to highlight the main policies of the last half century that have shaped the urban architectural fabric of Seoul today, and explore whether a modified approach might better address the current socioeconomic conditions in Korea. The paper defines and examines urban planning in Korea through an overview of the four main urban project policies implemented in Seoul from the 1960s to the present: Land Readjustment (LR), Housing Site Development (HSD), Urban Redevelopment (UR), and Housing Reconstruction (HR). While the fundamental ideology behind these policies served well during a prolonged period of high economic growth, evidence is growing that these policies are losing steam under today`s conditions. A growing legacy of stalled and incomplete urban projects from the mid-2000s-the New Town Project is an example-begs the fundamental question as to whether an alternative urban planning paradigm is needed for Korea in an age of low economic growth, low birth rates and a fossil fuel energy crisis. Through the urban morphologies of the three residential areas in Seoul developed by LR projects, this paper looks at the possibility of urban regeneration through the sustainment of urban architecture in those residential areas that have not been affected by HSD, UR, and HR.
A Study on the Estimation Method of the Environmental Load Intensity for Analyzing GHG Reduction Effect of Han-Ok
Kim, Sunghee ;

The Korean government recently has rediscovered the potential value of Han-Ok, the Korean traditional house, as an eco-friendly building. In order to objectively verify the environmental performance of Han-Ok as a low carbon green building, this paper suggests the analysis method of GHG emission load of Korean traditional house, based on Life Cycle Assessment, which is commonly abbreviated to "LCA". The environmental impacts caused by building construction and operation can be analyzed through the sum of input and output data from every phase. The study particularly describes the GHG reduction effect by using traditional building materials such as wood products, traditional clay roof tiles, and mud, which are mainly used to construct Han-Ok. Also the study proposes the method for comparative analysis of quantity of GHG emissions in building`s entire life cycle so that the data can be used as a reliable basis to optimize the environmental performance of building.

Offshore oil and gas process plants are exposed to hazardous accidents such as explosion and fire, so that the structural components should resist such accidental loads. Given the possibilities of thousands of different scenarios for the occurrence of an accidental hazard, the best way to predict a reasonable size of a specific accidental load would be the employment of a probabilistic approach. Having the fact that a specific procedure for probabilistic accidental hazard analysis has not yet been established especially for explosion and fire hazards, it is widely accepted that engineers usually take simple and conservative figures in assuming uncertainties inherent in the procedure, resulting either in underestimation or more likely in overestimation in the topside structural design for offshore plants. The variation in the results of a probabilistic approach is determined by the assumptions accepted in the procedures of explosion probability computation, explosion analysis, and structural analysis. A design overpressure load for a sample offshore plant is determined according to the proposed probabilistic approach in this study. CFD analysis results using a Flame Acceleration Simulator, FLACS_v9.1, are utilized to create an overpressure hazard curve. Moreover, the negative impulse and frequency contents of a blast wave are considerably influencing structural responses, but those are completely ignored in a widely used triangular form of blast wave. An idealistic blast wave profile deploying both negative and positive pulses is proposed in this study. A topside process module and piperack with blast wall are 3D FE modeled for structural analysis using LS-DYNA. Three different types of blast wave profiles are applied, two of typical triangular forms having different impulse and the proposed load profile. In conclusion, it is found that a typical triangular blast load leads to overestimation in structural design.
A Simple Procedure of Seismic Performance Evaluation for Unreinforced Masonry Buildings in Korea
Kim, Taewan ;

DOI : 10.5659/AIKAR.2013.15.3.159
This study was aimed at analyzing the three-step seismic performance evaluation procedure of Korea Infrastructure Safety Cooperation and proposing a new procedure suitable for unreinforced masonry buildings in Korea. For the study, it was investigated the performance evaluation results of five example URM buildings. First of all, it was found that the performance evaluation procedure for the URM buildings should be different from that for the other structural systems. As a result, a simple procedure of seismic performance evaluation was proposed, which includes elimination of elastic and inelastic push-over analysis and reduction of performance levels and evaluation steps. With the simple procedure, the URM buildings could be evaluated more easily than the other structures. It would be expected that the procedure can provide structural engineers with a simple and easy way to evaluate the seismic performance of the Korean URM buildings. Nevertheless, the procedure must be revised continuously by reflecting new research products for the URM buildings in Korea.

Due to increasing competition of construction companies, it is required to optimize the management of construction projects and "lean" concepts are rapidly spreaded in construction industry. Steel work accounts for a large proportion in construction work, and a variety of attempts to efficiently perform steel work has currently made. And since rebar (Engineer-to-Order) can be engineered through design once order is placed, it gives the great impact on construction, thus, entire management is required. The purpose of this study is to present the method to increase the efficiency of field processing method of steel work in terms of lean construction. Once we examine process of steel work and identify the flow, we would like to analyze which processes should be improved through value analysis approach and present the improvement plans. Also, this study examines cases of field processing and factory processing, and it identifies the waste factors in the procurement process. Finally, this study would like to present the result of analysis from the perspectives of value. The rebar delivery process is divided into several steps and the duration of every step is surveyed. Using duration data, VAT (Value added time) can be calculated for analyzing the efficiency of the process.
