The automotive front bumper guard is the most important part of the vehicle for protecting the life of driver when a traffic accident happens. In order to ensure safe driving, this part must possess sufficient strength and durability. This study was carried out with structural and fatigue analyses by designing front bumper guard models. After the lowest value for maximum total deformation and equivalent stress was found through structural analysis and the highest value for fatigue life was found for all three models, it was shown that the type C front bumper guard model was the most suitable for application to a real car. The strength property and durability of the optimum design were determined through this study's results.

Recently, due to the casualties and property damage caused by disasters, it became important to evacuate the victims to a safe place and come up with a space for them to inhabit for a certain period of time. Therefore, this study aims to design and develop a temporary housing system that would quickly provide a safe and comfortable living space until the displaced persons can return to a normal life again when a disaster occurs. As a result, a system of a BIM-based modular housing, a modular town through automatic placement, and a method to calculate the capacity and the total cost was developed. As this system provides the temporary housing facilities and the site in 3D, it can be utilized as a training material on a normal basis, as well as the first case material for rapid decision making when there is a disaster.

Determining the hysteretic energy demand and dissipation capacity and level of damage of the structure to a predefined earthquake ground motion is a highly non-linear problem and is one of the questions involved in predicting the structure's response for low-performance levels (life safe, near collapse, collapse) in performance-based earthquake resistant design. Neural Network (NN) analysis offers an alternative approach for investigation of non-linear relationships in engineering problems. The results of NN yield a more realistic and accurate prediction. A NN model can help the engineer to predict the seismic performance of the structure and to design the structural elements, even when there is not adequate information at the early stages of the design process. The principal aim of this study is to develop and test multi-layered feedforward NNs trained with the back-propagation algorithm to model the non-linear relationship between the structural and ground motion parameters and the hysteretic energy demand in steel moment resisting frames. The approach adapted in this study was shown to be capable of providing accurate estimates of hysteretic energy demand by using the six design parameters.

The development of digital technology makes our life more convenient in our lives and its calmness promotes the qualify of our life. Digital-home-automation system lets indoor-living more free, safe and clear so that it really has come true our life style that considers our mind and healthy to be important. Moreover, LED light source that combines the semiconductor with the digital technology has been tried as a current indoor illumination. Also the introduction of the light which has a high technology, like LED light, has been required in living space. It shows that it is very important to have an illuminated- plan which is accepted as well-developed technology. This study deals with the investigation into the user satisfaction of the existing residential area illumination and the investigation into the user satisfaction of the LED illumination being supplied for commercial area now. In the result, the fact is investigated that the user wants the introduction of the digital technology In the illumination because of a backward the residental area illumination in the circumstances being digital gradually. The inconvenience of the illumination used now should be minimized and the development of the LED illumination is a way satisfying the desire. The intended illumination project of the residential area should be accomplished according to the lifestyle of a changing residence.

The purpose of this study was to analyze the factors negatively affecting college life, to investigate the perception gap between housing types, and to generate preliminary data for increasing residential satisfaction of students who live in temporary housing(e.g., dormitory or one-room). The utilized research methods included a questionnaire survey and an in-depth interview. The college students, especially from other regions, experienced more financial difficulties than others. They managed their tuition and living expense/allowance by parents supports and other sources(e.g., scholarship, arbeit, work in college, loan etc.). The reasons to choose dormitory, as temporary housing, were short distance to college and low costs. In case of one room, independent life was main reason to choose. Gender differences affected to the decision, moving away from present temporary housing. For example, male students preferred an independent life and a short commuting distance, while female students preferred an independent life and a safe life. Thus, considering the origin and gender differences of residents, dormitory planning needed to develop plans allowing independent life and to choose appropriate site for the purpose. In case of planning one room apartment, concerns for safety and landscape were more important than other factors.

주민들의 여가 활용 기회 확대와 복지 증진에 근거한 옥외생활양식의 변화는 각 도시의 도시로, 공원, 광장 등의 환경정비사업의 활성화에 크게 영향을 미쳤다. 또한 이는 즐겁고 풍요로운 도시 공간의 조성이 지역의 개성을 반영한 독자적인 문화적 가치를 부여한다는 의미 외에도 이러한 도시환경을 관광자원화 하려는 의도를 수용하고 있어서 각 지방 자치 단체들 이 관련 도시계획을 수립하고 이를 추진하는데 힘을 얻고 있다. 시민들의 옥외생활이 안전하고 건강하며, 쾌적하고 능률적으로 이루어지기 위해서는 해당 장소마다 그 지역의 생활양식에 상응하고 사용 공간에 문화적 개성을 부여한 외부시설물의 디자인이 필요하지만 그에 대한 체계적인 연구와 개발 사례가 아직은 부족한 실정이다. 본 연구는 2003년 말 개통 예정인 광주광역시 지하철 1호선역을 대상으로 그 공간에 우선적으로 필요한 외부시설물 8종을 선정하여 디자인 개발한 사례를 정리한 것이다

21세기 일본의 학교안전은 학교교육 정책의 변화에 따라 직접적인 영향을 받았다. 일본 학교교육의 목적은 "살아가는 힘(zest for life)"을 증진시킴으로써 자립 협동 창조적인 인간으로 육성하는데 있다. 이를 반영하여 학교안전의 목적도 어떠한 재난 상황에서도 학생 스스로 극복할 수 있는 생존 역량을 강화하는데 두고 있다. 일본 학교안전의 주요특징은 다음과 같다: 1) 스스로 살아남을 수 있는 역량 강조 2) 가정 및 지역사회의 학교안전 역할 중시 3) 학교안전과 학교교육의 균형 4) 체험학습 및 능동적 학습(active learning)을 통한 안전교육 강조 5) 안전한 학교시설 추구 6) 학교안전 개선을 위한 PDCA(Plan-Do-Check-Act) 적용 7) UN 안전학교 모델 도입 및 확산. 일본 학교안전에 대한 논의는 최근 제도적 변화가 급격히 이루어지고 있는 우리 나라 학교안전에 의미 있는 시사를 줄 것이다.

초고층 빌딩 건설 시 요구되는 성능위주 소방설계는 인명 안전을 확보할 수 있는 능동적인 대책으로서 화재 위험성을 평가하고, 공학적 분석 결과를 토대로 하여 방재시스템을 구축하는 것으로 관련 법규 및 기준을 적용하여 수행하는 기존의 설계 방식보다 인명 안전의 확보에 있어서 매우 효율적이고 타당하다고 보여진다. 본 연구는 피난 요구 시간인 RSET과 피난이 가능한 시간인 ASET에 의한Time-line Analysis을 적용하였으며 또한 ASET과 RSET을 비교, 분석하기 위하여 화재 및 피난 시뮬레이션을 수행하였다. 연구 결과, 스프링클러설비가ASET을 증가시켰으며, 화재감지 및 경보시간의 단축이 RSET을 효과적으로 감소시켜 주고 있다. 단축된 시간은 인명의 안전을 확보하는데 많은 영향을 미치는 것으로 확인되었다. 또한 소화설비, 화재 감지 및 경보설비가 정상적으로 작동되도록 유지 관리되는 것도 중요한 것으로 파악되었다. 화재의 성상을 데이터 베이스화하고 피난 대응 프로그램 등이 구축되면 성능위주 설계에 유용한 자료로 이용될 수 있다.
