The modern contains many problems that cannot be solved by the reductionism based on western natual science. Up until now, it has been formed determinism over the basis of empiricism or rationalism, this can be called a mechanical view of the world. In the field of natural science since 20C, however, raised the standard of revolt in traditional determinism, plural theory headed up. Consequently, in the name of post modernity, western reason became to deconstruct, further, new theory came to need. This new paradigm also affected design, and was studied to overcome the limitation of modern design.

Before incorporating the earthquake-resistance design in design standard (1988) in South Korea, most of existing residential buildings were built without having lateral resistance capacity in addition to their structural peculiarity, such as exterior stair ways, exterior elevator room. For these reasons, the demands on retrofitting research for existing buildings arise recently and many retrofitting methods are proposed. These tasks are important to reduce the enormous economic loss and environmental issues. As the main purpose, this study was intended to examine the performance improvement in terms of ductility and strength in the wake of retrofitting and to suggest retrofitting details.

This paper presents a prototype of document schema to guarantee the consistency of the bridge design information during the life-cycle of bridge. The main component of document schema for bridge design information is derived from the Document Type Definition (DTD) Pool which is the Construction CALS/EC standard in Korea and the document schema is implemented by using the XML Schema. The ifcXML are adopted for representing product data of bridge. A pilot system adopting the document schema and its application to existing bridge show that the suggested document schema can be efficiently used to develop software modules supporting the integrated design documents for bridges.

The Korean Bridge Design Standard Specifications adopted the seismic design requirements in 1992. However, The current seismic design requirements for bridges are based on the USA seismic codes for sever earthquake. This provides the basic factors that affects the performance of spiral reinforced concrete piers for seismic loading, and The specimen tests are performed based on load-displacement, effective stiffness and displacement ductility, etc. The quasi-static test was adopted in order to investigate seismic performance of the spiral reinforced concrete pier specimens which had different transverse steel amount, spacing and longitudinal steel ratio under different axial load levels. This study is concluded that seismic design for transverse reinforcement content of spiral reinforced concrete column has influenced on axial load and effective stiffness etc.

This study is based on the Importance of home office in domestic environment in Korea. In recent years, the distribution of network environment at home has been changed rapidly Each family member uses home office for various purpose. The home office in domestic living environment become a part of common use for all family member. The purpose of this study is to set the framework of design direction in terms of system furniture for home office within the limitation of current standard space at home such as typical apartment - 30 pyeong, 40 pyeong. The first step of study is to understand user space and user needs through the user survey. The second step is to find the right location and plan of home office in domestic environment. The last is to suggest the integral system furniture and elements that fits to the various situations of location according to the space and user type.

Test procedure for the design verification of wind turbine pitch and yaw bearings has been developed. Test items were selected to evaluate operational reliability of pitch and yaw bearings by considering loading and operational conditions, and by analyzing the design criteria of pitch and yaw bearings. The developed test items consisted of preliminary test, fatigue load test, extreme load test, low temperature environmental test and dismantling inspection after all the test were completed. Because it reflects the actual operational conditions of the pitch and yaw bearings, the developed test procedure has high reliability and can verify the basic design considerations in the international standard and guidelines.

A 22.9kV/50MVA class high temperature superconducting(HTS) power cable system was developed in Korea. For the optimization of electrical insulation design for a HTS cable, it is necessary to investigate the ac breakdown impulse breakdown and partial discharge inception stress of the liquid nitrogen/laminated polypropylene paper(LPP) composite insulation system. They were used to insulation design of the model cable for a 22.9kV class HTS power cable and the model cable was manufactured. The insulation test of the manufactured model cable was evaluated in various conditions and was satisfied standard technical specification in Korea. Base on these experimental data, the single and 3 phase HTS cable of a prototype were manufactured and verified.

This study is concerned wiか the practical optimum design of concrete framed structures considering serviceability - deflection, crack, fatigue. The optimizing problems of framed structure are formulated with the objective function and the constraints which take the section properties as the design variables. The objective functions are formulated as the total cost of the structures and the constraints are derived by using the criteria with respect to safety and serviceability based on the part of concrete bridge in the Korea standard code of road bridge. The SLP method is introduced to solve the formulated nonlinear programming problems in this study and tested out through the numerical examples. This developed optimizing algorithm is tested out and examined through the numerical examples for the practical use of design on the concrete framed structures. And their results are compared and analyzed to examine the possibility of optimization, the applicability and the convergency of this algorithm.
