The purpose of this study is to reveal the kind of traditional perspectives we can use from the past to create a sustainable society for the future and to contribute to the growing interest in, and concern for, environmentally-sound designs. Such perspectives include ways to sustain naturalistic aesthetic views, elements of architectural design, and ideas for traditional lifestyles. Architecture that used these methods would contribute to a more ecologically sensitive view of man's place within the natural environment. This research was conducted by way of literature reviews; the objects of study were physically extant traditional housing, the composition of the traditional village, and traditional lifestyles. The results of this study indicate that the ecological characteristics of traditional Korean homes originated from a holistic conception of society and nature; this holistic conception has been found lacking in our more modern, western influenced homes. In the past, in order to leave an unpolluted or even healthier natural environment to descendents, it was essential to apply ecological principles. Villages harmonized with nature and houses were designed to utilize sunlight and wind. Their natural construction promoted consciousness of human beings and their symbiotic relationship with nature.

Design of experiments based on Taguchi's orthogonal array is utilized for exploring the design space and for building response surface models of insulator and isolator database in order to facilitate the effective solution of multi-objective optimization commonly occurred in NVH problems. Response surface models, called engineering database of design space, provide an efficient means to rapidly model the trade-off among many conflicting NVH goals in automotive. In the design of insulator and isolator in automotive interior part, it is important not only to construct effective matrices of NVH but also to build up engineering database of current products. The experimental design especially based on orthogonal array and the nonlinear optimization algorithms are successfully used together to obtain the optimal design of insulator and isolator. The $2^{nd}$ order response surface models of absorption coefficient and insertion loss are constructed by using modified Taguchi's $L_{12}2^13^7$ orthogonal array and successfully used in optimal design of insulator and isolator.

On account of the increasing crime rates annually and the consequent rising anxiety, safety has become an important topic in the aspect of environmental formation to provide decent lives to urban dwellers. As a result, great emphasis has been placed in the importance of Crime Prevention through Environmental Design (CPTED), a design method which utilizes physical environmental design to prevent crime. The definition of CPTED encompasses the technological level of crime prevention as well as comprehensive environmental design which takes into consideration fear or terror in view of human recognition and emotion. However, the current application method of CPTED in Korea is still limited to the technical supplementation of facilities, such as CCTV and streetlight, and fragmental modification like village mural paintings. Moreover, the guideline for CPTED in Korea is only a theoretical adaptation of foreign books and does not offer sufficient studies for a practical design method that will improve the life of city dwellers. The purpose of this study is to examine design methods for safe environment construction in accordance with the changing concept of CPTED by understanding the characteristic of space and analyzing the how the methods of light are expressed. This study aims to provide basic material which will serve as a guideline in creating a safe environment in the future.

The purpose of the study is to analyze the planning characteristics of outdoor space in apartment complexes in terms of child-care environment. We selected 8 apartment complexes in Cheongju, within three years from construction, of small and medium-sized apartments ($60-85m^2$) where a large number of families with young children are presumed to reside in. As a result of the study, it was found that whereas the factors that can be quantified such as the floor height differences, the angles of ramps, and the number of the rest facilities are excellent, the qualitative part which cannot be easily quantified such as the location and direction of the rest facility and play materials should be improved a lot. And the following improvements were suggested; separating the pedestrian passage from the vehicle road in the main entrance of the complex, utilizing the piloti for infant caring, making the entrance area of apartment safe for pedestrians from vehicles, reallocating resting spaces, redesigning resting spaces safer to infants, building or reallocating existing booths at the stops of kindergarten buses, redesigning the square safer from vehicles with shades, making it possible for guardians to watch infants in playing field from the resting space, allocating natural environments essential for child development.

In the inner turn key constructions the problems of uniform types are repeatedly occurred, and, especially, many problems happen up to the stage of pre-construction(from a bid to a contract) owing to the specialties of the turn key constructions. So the claim factors of the Korean turn key constructions were abstracted through the literature searches, the site document examinations, the case studies and the interviews with the experts. When the technicians meeting the interior turn key constructions for the first time and working here now are well acquainted with only these factors, many claims will be prevented. By analysing the degree of claims by claims factors through the questionnaires to the experts about the abstracted factors and surveying the amount of the claims through the case studies, what factors exerted how much of influence on the claims was tested and analyzed. Proposing the response devices to the factors affecting the claims much led the technicians in charge of internal turn key constructions to the prevention and the proper solution of the site claims.

Generally, a box tube, which is used for an existing square CFT structure, is made by welding four plates. The manufacturing efficiency of this steel tube is poor, and it also needs special welding technology to weld its internal diaphragm and the through diaphragm. Therefore, an interior-anchor-type square steel tube was developed using the method of cold-forming thin plates to prevent welding of the stress concentration position, and to maximize the section efficiency. And, considering of the flow of beam flange load, the efficiency of erection and the weldability of the diaphragm to thin walled steel column, the external diaphragm connection was selected as the suitable type for the welded built-up square CFT column to beam connection. And, an analytical study and tests were conducted to evaluate the structural performance of the suggested connection details and to verify the suggested equations for the connection details. Through this study, the composite effect of the internal anchor to concrete, the resistance and stress distribution of the connections before and after the existing column is welded to the beam, the effective location of welding in connection were analyzed.
