이중외피와 할로우 코어를 적용한 초고층 주거건물의 에너지 절감 방안에 관한 연구
이승복,원종서 대한건축학회 2005 대한건축학회논문집 Vol.21 No.3
The environment pollution is very important problem. Even at the field of architecture, a study about method of energy saving and constructing environment friendly building will have performed with activity. But trends of Korea housing market are changed that the height of building become more higher and the level of comfort going up. Therefore, these requirements force to increase the energy usage for indoor environmental controls. Thus, this study aims at reducing the heating and cooling energy requirements of high-rise residential complex using twin skin facade and hollow core. Based on ESP-r simulation, the alternatives of facade design compare to the conventional facade design. The alternatives is as following. 1) Basecase(expanded balcony), 2) Expanded balcony + Hollow Core, 3) Twin Skin facade, 4) Twin Skin facade + Hollow Core. If outdoor temperature higher than 26℃, the air temperature of passing hollow core low maximum 7℃. In winter, the air temperature of passing hollow core higher outdoor temperature. Thus using hollow core could reduce heating and cooling energy. It was confirmed that the possibility of natural ventilation strategies through twin skin facade during mid-term(15℃~26℃). The flow rate assumed from 0.74 ACH to 23.80 ACH(average flow rate 7.56 ACH). Therefore, If utilize twin skin facade at the high-rise building, natural ventilation could possible and cooling energy could reduce. The results of the simulation show that the facade using hollow core could reduce 16% of heating and cooling energy, the twin skin facade could reduce 85% of heating and cooling energy, the facade using hollow core and twin skin could reduce 88% of heating and cooling energy compared to conventional facade design.
한국의 초-중등 EFL 교육 상황: Behaviorism인가 아니면 Nativism인가?

The purpose of this study is to provide Korean primary and secondary school teachers of English with some practical ideas for the development of teaching methodologies in their English classrooms. The researcher critically analyzes the limits of traditional teacher-centered methods based on the Behaviorism theory and suggests as an alternative some teaching ways based on the Nativism theory in order to overcome the limits found in Behavioristic ones. The focal points of the Nativistic approach defined by the researcher are 1) humans’ language competence is a kind of biological faculty, 2) all biological faculties should follow the natural routes and orders, and 3) language acquisition procedure is not an exception as an a natural phenomenon. In line with the Nativism theory, the researcher provides very specific examples for the Korean teachers of English to be able to practice in their EFL situations.
