  • This study aims at providing suitable outdoor spaces for physical, social, and psychological condition of Korea elderly, examining design characteristics and presenting design guideline of outdoor space for elderly. To do this, this study examined previous research papers and scholastic writings, related to elderly housing, and analyzed existing outdoor space for elderly. Additionally evaluation of usage pattern and physical trace carried out four silver towns. As a result, first, the study showd that characteristics of outdoor space are related to safety, amenity, recognition and efficiency. Second, types of outdoor space in elderly related facilities are very limited in verity, just facilitating with rest space, sport space, and garden space. Third, from a standpoint of barrier-free-design, four silver town cases are not carefully concerning about outdoor space for elderly. These spaces should be designed for both neighborhood and elderly people.

  • There are two relaxation frequencies in orthogonally polarized dual-mode solid-state lasers. Complex dynamic behaviors such as chaos can be observed by modulating orthogonally polarized dual-mode solid-state lasers. In this paper, we derived Maxwell-Bloch equations by considering anisotropy explicitly in laser-atom interactions and explained the complex nonlinear dynamical behaviors.
