Programmable Kiri-Kirigami Metamaterials

Programmable kirigami metamaterials with controllable local tilting orientations on demand through prescribed notches are constructed through a new approach of kiri-kirgami, and their actuation of pore opening via both mechanical stretching and temperature, along with their potential application as skins for energy-saving buildings, is discussed.

A Planning Methods for Apartment Unit's Remodeling in terms of Low-Fertility and Aging Society

An increase of single and/or two-people households with decrease on typical three or four people households (which was defined as sizes for nuclear family) has led to varieties in family formations and lifestyles. It is not just a reduction on number of family members but generates several issues. Apartment, which has been the typical contemporary housing type in Korea, have a difficulty to satisfy emerging demands of various residents, due to standardized unit plans and mass supplies. Based on remodeling cycles of apartments, it becomes a time period that requires a significant number of remodeling on degraded apartments. Recently, as an alternative, development of urban small housing has been encouraged in national level as a solution to meet increasing needs of small housings and increasing needs for improving living environments in degraded residential areas. Years of consistent massive volume of housing supply policies, which was to ease the housing problem by quantitative way, was pointed out to be a leading problem of providing poor living environment. Therefore, it is necessary to develop an architectural planning guideline for degraded apartment remodeling that able to accommodate need of residents with variety of lifestyles and ensure better residential environment. In this paper, we first determine the changes in life styles of residents and public housings through the statistical data analysis then investigate architectural planning method for apartment remodeling in terms of low-fertility and aging population.

Utilization of Scientific Method as a Tool of Architectural Design

Science (natural science) is the systematic attempt to understand and interpret the nature phenomenon. For this reason, architects have used science to adapt nature to their design. With the rise of modern science, architecture became more closely related with science. Science available to develop new technology for architecture and it influenced architect’s idea and concept. Symbolically, Architects use method or process of science to generate building form. The Rules of compositing particles in the chemistry or DNA (deoxyribonucleic acid) in the biology are used to generate a form of building. Literally, Architects use technology as a tool of science to improve physical performance of architecture. Like mathematical understanding of structure load enabled people to construct enclosure without columns or any of support system inside of architecture. Still natural phenomenon is not fully understood as science and science is still discovering a new phenomenon or changing its theory to adapt new discovery. New discovery or limitation of science influenced architecture throughout the history. This paper is to discuss how architectural theories are rest upon idea set forth by science. In addition, how technology as a tool of science has been utilized in architecture.
