From an sustainable perspective, one unique characteristic of Open Housing is its ability to individualize variable elements (infill) from the permanent elements (support) in accordance with the residents' needs. Such environment-friendly elements of Open Housing can contribute to increasing the life span of the building, reducing the scope of reconstruction, and minimizing the amount of disposed building materials during demolition. The purpose of this research is to analyze the flexibility concept from a typological perspective, so that the concept of open housing can be better understood and its development can be promoted. The main method of this study was content analysis. Based on literature review of flexibility concept in a typological approach, a primary categories were established to describe the flexibility concept such as time for flexibility, scope, and the degree of openness. Subsequently each criterion was elaborated as follows: planning, supply, and utility in the time stage; internal and external flexibility in its scope; and fixed, semi-free, and free flexibility in its openness degree. This research exposes the lack of comprehensive knowledge of Open Housing caused by rather uniform features of previous studies. This research establishes and promotes a systematic approach for a more holistic meaning of Open Housing. This approach should contribute to the proper utilization and further development of sustainable housing.

This study is connected with evaluation of the progressive collapse resisting capacity for sustainable RC super tall building design. As the progressive collapse is not considered in current design codes in Korea, differences between linear static and dynamic analysis based on the GSA guidelines was analyzed for better evaluation, and the analysis model of flat plate system was determined. Finally, the progressive collapse resisting capacity was evaluated for structural system of super tall building. According to this study, the results by linear dynamic analysis were underestimated than the results by linear static analysis. Thus, the dynamic coefficient value of 2 provides conservative approach. The Effective Beam Width's model, currently used in field, is useful for the analysis about lateral force, but this model does not consider the effect of load redistribution by the slab. Hence, finite element analysis considering slab element will be needed for progressive collapse resisting capacity of the flat plate system. Finally, analysis model of 80-story building designed based on KBC(Korea Building Code) shows the weakness against progressive collapse because the DCR value is over 2. Thus, the countermeasure for alternative loading path such as installment of spandrel beam and reinforcements around slab is required to prevent the progressive collapse.

가뭄을 전망하는 방법으로는 통계적 방법과 물리적 방법으로 구분할 수 있다. 통계적 방법은 과거의 기상 및 수문현상이 미래에도 재현될 수 있다는 전제하에 미래 가뭄상황을 전망하는 방법이다. 그러나 이 방법은 예측된 결과들이 모두 과거의 경향에 국한됨에 따라 최근에 급변하는 수문기상의 특성을 고려하는데 한계가 있다(Trenberth, 1994). 물리적 방법은 주어진 초기 수문기상조건으로부터 역학적 알고리즘이 탑재된 기상 및 수문모형의 연계모의를 통하여 미래 가뭄을 전망하는 방법으로 모형에 따른 불확실성이 발생할 수 있으나 최근 수문순환의 변화를 예측가능하다는 장점이 있어 활용도가 높다. 본 연구에서는 기상예보자료와 지표수문모형을 연계한 물리적 기반의 수문학적 가뭄전망정보를 산정하고, 활용성을 평가하였다. 기상예보자료는 기상청 현업예보 모델인 GloSea5로부터 생산된 자료를 이용하였으며, 수문학적 가뭄전망을 위해 MSWSI (Modified Surface Water Supply Index)를 활용하였다. 수문학적 가뭄전망정보는 현재의 수문조건이 지속된다는 가정하에 예보선행시간 3개월까지 산정하였다. 2015~16년 기간에 중권역별 가뭄전망정보를 산정하였으며, 전망정보의 예측성은 통계분석을 이용하여 정량적으로 평가하였다. 금회 제시한 연구방법은 현재의 수문조건이 지속될 시 기상예보에 따른 중권역별 수문학적 가뭄을 예측할 수 있다는 점에서 활용성이 높을 것으로 판단된다.

과거 우리나라 하천관리 정책은 이수와 치수 기능 위주로 개발됨에 따라 하천 수량이 감소하고 오염이 심화되는 등 하천환경이 계속적으로 악화되어 왔다. 시대가 변화함에 따라 하천환경 개선에 대한 패러다임과 사회적 요구의 변화로 인간과 자연이 더불어 살 수 있는 친환경적인 하천을 조성하고 훼손 또는 변화된 하천을 복원하는 노력이 필요하다. 하지만, 본래 자연상태의 하천으로 완벽하게 회복 될 수없다는 한계점이 있기 때문에 하천이 갖고 있는 하천공학적 기능을 최대한 유지하면서도 다양한 수생생물의 서식처의 기능도 되살아나게 해야 하는 복합적인 목적을 갖춰야 하며, 하천 수생생물의 서식처 복원을 위해서는 하천생태계에 필요한 환경유량의 정량적인 평가와 확보방안 및 공급방안의 검토가 동시에 필요하다. 본 연구에서는 하천유지유량이 생태계 기준으로 고시된 하천인 감천유역을 대상으로 물수급 분석을 통해 환경생태유량 확보할 수 있는 방안을 고려하고자 하였다. 물수급 분석을 위해 K-weap을 활용하였으며, 공급 우선순위, 저수지 운영 변화 등을 통해 제한된 수자원을 효율적으로 활용하여 방안을 제시하고자 하였다. 추후 하천 수생생물의 생애주기와 계절적 변화 등을 고려한다면, 더욱 합리적이고 지속가능한 환경생태유량 확보방안을 제시할수 있을 것으로 기대된다.

The bearing wall apartments which occupy the majority of multi-residential apartment buildings built in Korea, are known for having limited architectural plan flexibility, posing challenges in terms of maintenance and remodeling. The economic losses and environmental issues resulting from the reconstruction of bearing wall apartments are now accumulating to the extent that they are becoming a national concern. Multi-residential apartment buildings, which are now the dominant form of residence in Korea, must accommodate diverse customer needs and changes in life style. A new concept of Rahmen structure with architectural flexibility is Green Frame. GF multi-residence housing is expected to reduce construction costs and shorten the construction schedule by overcoming the shortcomings of conventional bearing wall apartments. This goal is consistent with the national policies that target the reduction of resource and energy consumption. In addition, GF will be established as a core contributor to achieving a reduction in $CO_2$ emissions, which will enable the sustainable growth of domestic construction industry, and address the low-carbon green growth drive implemented by the government.

본 연구는 건축고도제한에 의해 생태학적 조경설계는 어떻게 통제되며, 또한 생태학적 조경 설계가 무엇인가를 구명하는 것이다. 따라서 두 가지 다른 단지를 비교하여 건축물 스카이라인이 주변경관과 조화로운 심미적 설계를 가능하게 하는 영향에 관하여 고찰할 수 있다. 이 비교를 통하여 스카이라인 통제가 아파트단지 계획과 설계에서 생태학적 조경설계에 영향을 주는가를 검증하게 될 것이며, 스카이라인이 통제된 아파트단지가 조경시설 설계에 있어서 전체적, 역동적, 반응적, 직관적 접근을 할 때 상대적으로 우선성을 표출할 수 있을 것이다. 아파트단지 계획·설계에 있어 건물고도제한이 적절하게 검토되어 스카이라인의 통제를 더 강하게 할수록 아파트단지에서 만들어진 조경환경의 특성이 강조되고 강화한 경관이 더 조화롭게 된다는 점에서 경관에 유용하고 편익이 있다. 생태학적 조경설계의 평가사항은 자기 지속적, 자연적·문화적 정체성, 개연적 외관, 생태학적 접근으로 이뤄진다는 전제 아래 세부사항 18개 항목을 표출하였다. 또한 스카이라인 통제는 자연적 경관을 보전하고 수목이 단지의 안팎으로 자연스럽게 펼쳐지는 녹지 네트워크와 야생 동물 코리도를 획득하기 위하여 독특한 경관을 설계하고 개성적인 것으로 도출하여 조화로운 심미성을 이룩하는데 유용하다는 것을 계량적으로 표출하였다. 아파트단지의 경관에서 의미 있는 것은 다양한 접근으로 설계되고 건물 스카이라인 통제방법을 강화함으로써 관리되는 스카이라인의 실루엣이 다양하고 개성적 형태를 표출한다는 것을 보여준다. 결과적으로 스카이라인의 영향과 생태학적 조경설계가 계량적 요소에 의해 상대적으로 비교될 수 있으며, 생태학적 조경설계의 평가시설지표는 보다 세분화됨으로써 전체적인 설계요소의 강도에 영향을 줄 수 있다.
