This study investigates the analysis result of structure and fatigue due to the models of the hub space with bolt joint at wheel and the existence or nonexistence of hub ring as the part of suspension system of vehicle. As the static analysis result, the structural vulnerability can be found at hub bolt and the center of wheel at three models. Model 2 and 3 have nearly same deformation and model 1 can be endured at the least load among three models. As the fatigue analysis result, fatigue lives of three models are same at the severest load of SAE bracket history. As many screw threads of weak bolts are jointed in case of model 1, model 1 is shown to be the weakest at fatigue damage among three models. By the result of this study, model 1 with bolt joint becomes most weakest among three models. As model 2 with no hub ring and model 3 with hub ring have the nearly same states of analysis results, hub ring is shown to have no influence on the safety of automotive driving.

The academic library has the ideal environment as a facilitator of knowledge creation, as a space where researchers can collaborate and as a creation hub center on campus. Recently, based on the 4th Industrial Revolution and creative theories, the maker space is gradually being introduced into academic libraries in foreign countries. Maker Space of the academic library is the best place to discover new knowledge and interests, practice, and interdisciplinary education. In this study, we propose a plan to introduce the maker space of domestic university libraries through case studies of domestic and overseas university and university libraries.

최근 데이터 분석을 위한 연구 환경은 고성능 컴퓨팅자원, 대용량 스토리지, 초고속 네트워크 시스템등 IT 기술이 융합된 사이버 인프라 연구 환경을 기반으로 하고 있다. 또한, 실험의 규모가 커지면서 다수의 연구자들이 협업을 통해 공동의 연구결과를 도출하는 집단연구가 증가하고 있다. 본 논문에서는 이러한 환경에서 연구자들이 대용량 실험데이터를 공유·분석할 수 있는 효율적인 스토리지 작업 공간 모델을 제안한다.
