Now interior designers have to meet this challenge by rising to the occasion and taking advantage of opportunities while strengthening their skills which have not kept pace with the increasing emphasis on design. furthermore, they are hampered by the lack of a general working design methodology. Interior designers in Korea have been slow to recognize the need for developing a specification methodology manual which could be adapted to meet varying requirements and modified to reflect designers experiences. The design process in Korean interior design often involves utilizing drawing document methods based on architectural prototypes rather than upon drawing methods developed by design firms as a result of work experience s and unique needs. However, these unique nees are nearly always limited by traditional working drawing methods. This has led to confusion and inaccuracies due to the lack of a single starndardized and universally acceptable working drawing methodology which is capable of reflecting the needs of all parties involved , partiality those of interior designers. This thesis is an attmepted to establish the necessity for developing a better working drawing methodogoy or technical mans of satisfying the information sorting and processing need s of interior design professionals, a five step suggestion for developing such a methodology follows. First, arrange pertinent design research information by means of a process which can be employed throughout the design process, from inception through to working drawing stage. The end result should be an interior architectural design process culminating in a pattern skillfully blending architecture, vision and product with environment . The design process should be manifested into a series of definable steps and yet sufficiently flexible and variable in order to provide the most apropos design solution. Secondly , motify the design methodology systematically according to site conditions and prevailing construction technology and manifest the design process in a booklet form so that it reflects a desired pattern. Thirdly, this methodology should incorporate a stand-ardized and functional process capable of being utilized to impact clear design concepts and objectives with preci-sion and efficiency in a manual form.

The purpose of this study was to develop and evaluate working clothes for shipbuilding workers who work in one of the poorest work environments among national strategic industries that are playing pivotal roles for the Korean economy. For the study method, requirements collected through interviews and field surveys were incorporated to directly weave the fabrics for working clothes. The colors were then selected and the woven fabrics were dyed with the selected colors. Using these, the designs of working clothes were planned from the construction and design aspects and four winter clothes and four spring and fall clothes were produced. Afterwards, the workers dressed in these clothes and workers and managers evaluated them in terms of appearance, color satisfaction, design satisfaction, and safety mind harmony on a five point scale. This study found that the new working clothes offered better functionality, design, and safety compared to existing working clothes.

턴키 공사의 실시설계 단계는 기본설계 이후 최종 계약을 위한 준비 단계로써, 수행하여야 할 업무가 많을 뿐만 아니라, 그러한 업무의 결과가 실제 계약서류에 대한 근거가 되므로 턴키 사업 수행자 입장에서는 철저한 관리가 필요한 단계이다. 그러나 국내 건설회사의 경우, 최근까지 단순히 시공 주체로써의 능력만을 키워왔으며 턴키 사업에 대한 경험이 미비하여, 실시설계 단계의 프로세스와 기존사례가 체계화되어 있지 않아 현장관리자가 해당 프로세스에서 업무를 수행하는 데 어려움이 있었다. 이를 해결하기 위해, 먼저 턴키 사업의 이론적 고찰을 통하여 연구의 근거와 필요성을 제시하고, 현장관리자 면담을 통해 실시설계 단계에서 수행하여야 할 업무와 그에 따르는 제반사항에 대해 파악한 후, 실제 발생하였던 의사결정 사항들과 그에 대한 대처방안 및 예방방안에 대해 조사하였다. 그리고 면담조사 결과를 바탕으로 턴키 공사의 실시설계 단계 프로세스 모델과 CBR(Case-Based Reasoning)을 활용한 실시설계관리 방안을 제시하였다.

To find the working condition is one of the important factors in precision machining. In this study, we analyzed maximum working temperature by infra-red camera and surface roughness in side wall end milling using design of experiment (DOE): RSM(response surface methodology), ANOM(analysis of means) and ANOVA(analysis of variance) by table of orthogonal array. ANOM and ANOVA are well adapted to select sensitivity of design variables for maximum working temperature and surface roughness. The effective design variables and their levels should be determined using ANOM, ANOVA. RSM is presented 2nd order approximation polynomial of maximum working temperature and surface roughness is composed with design variables. Therefore, it is expected that the proposed procedure using design of experiment : table of orthogonal array, ANOM, ANOVA and RSM can be easily utilized to solve the problem of working condition.
