발목 운동 방법 - 벽과 수건을 이용한 발목 운동 방법
김지현,Kim, Ji-Hyeon 대한산업보건협회 2020 산업보건 Vol.387 No.-
인체면적의 고작 2%를 차지하는 발바닥은 체중의 98%를 지탱하고 있습니다. 그래서인지 근골격계 질환 중에서도 손상이 빈번하게 일어나는 부위가 발목관절인데요. 스포츠 활동뿐만 아니라 일상생활 중에도 손상이 잘 일어나며 한번 손상되면 발목관절 안정성이 떨어지게 되어 재손상이 쉽게 발생합니다. 이에 발목관절 건강을 지킬 수 있는 적절한 예방운동이 꼭 필요합니다.

Escherichia coli에서 플라즈미드 pBR322 DNA와 단백질의 복합체를 분리하여, micrococcal nuclease로 처리하였다. Histone 유사단백질들의 결합에 의해 nuclease가 작용하지 못한 DNA 부분에 해당하는 DNA 조각들이 생성되었다. pBR322 DNA상에 임의로 정한 구획들에 histone 유사단백질들이 결합하는 정도를 상대적으로 측정하였다. pBR322 DNA의 각 구획에 이 단백질들이 결합하는 정도가 전사에 의해 받는 영향을 분석하였다. The deoxyribonucleoprotein complex of plasmid pBR322 was isolated from Escherichia coli cells and was treated with micrococcal nuclease. Nuclease-resistant DNA fragments were obtained due to the binding of several histonelike proteins. The relative extents of protein binding on arbitrarily divided regions of pBR322 DNA were measured. The effects of transcripticn on the protein binding to each region of pBR322 DNA were analyzed.

본 연구는 기후변화 대응을 위한 계획적 수단으로서 옥상녹화에 따른 건축물 에너지 저감효과를 분석하여 옥상녹화 적용확대를 위한 기초자료를 제시하는데 목적이 있다. 대상지는 최근 준공된 공동주택 중 옥상녹화가 적용된 주동과 부대복리시설을 선정하였다. 건축 유형에 따라 경량형(토심 20cm) 및 혼합형(토심 40cm) 옥상녹화를 적용하고, 디자인 빌더(Design Builder)를 활용하여 옥상녹화 적용에 따른 에너지 저감량을 비교 분석하였다. 분석결과, 모든 대상 건축물에서 옥상녹화 적용시 에너지 저감효과가 있으며, 혼합형 옥상녹화가 경량형 옥상녹화에 비해 냉 난방 에너지 저감효과가 더 큰 것으로 나타났다. This study aims to provide basic materials for expanding application of green roof afforestation by analyzing structures' energy consumption reduction effects according to green roof afforestation as a planning means to cope with climate change. As the subjects, recently completed apartment buildings and service facilities of apartment houses where green roof afforestation was applied were selected. green roof afforestation of Extensive Green Roof(soil depth: 20cm) and Semi-Intensive Green Roof(soil depth: 40cm) in construction types was applied and design builders were utilized in order to compare energy reduction amount according to the application of green roof afforestation. According to the analysis result, all the buildings had energy reduction effect when green roof afforestation was applied.
기후변화에 따른 녹색건축인증제도의 외부환경 평가항목 개선방향 연구

In 1990s, as the extreme weather events according to the global warming climate change are occurred frequently all around the world and the scale of the damage increases, the developed countries are promoting various policies for reducing greenhouse gas emissions setting the goal of greenhouse gas reduction with the level of State and local government. Especially for the greenhouse gas reduction of buildings and the inducement of eco-friendly design, the green certification system is strengthened with the assessment of energy and greenhouse management, and recently, according to the policy change of climate and energy, the certification system expanded from the buildings to the level of city and district is piloted. So this research is to understand the main contents and the assessment system of domestic green building certification system implemented in March 2013 in response to the policy change of climate and energy and to suggest the basic data for the improvement of present domestic greenhouse certification standard through the analysis of actual certification and the main case analysis of international green certification system. Recently in developed countries, in 1990s, for the reduction of building's greenhouse gas emission and the inducement of eco-friendly design, from the building of LEED, BREEAM, DGNB to the level of city and district such as LEED Neighborhood Development, BREEAM Communities, DGNB Stadtquartiere, the system is expanded and piloted. On the contrary, as for the domestic standard of green building certification system, the distribution ratio according to the assessment items in each category consists of the assessment system based on the buildings, and just the simple adjustment of some items and the improvement of weighted value are performed. Actually, as a result of selecting the 30 districts of apartment housing with the most certification performance by use among the 49 buildings certified by Institute of Land & Housing from December 2014 to July 2016 and analyzing the assessment score, the certification level is determined by the sectors of high distribution like indoor environment and energy not by the ineffective sector of external environment with low distribution so this system has a limitation to perform the practical means for the policy change of climate and energy. Thus for the national green building certification standards, the assessment system in the sector of external environment is to complemented and furthermore, reflecting domestic reality, through the introduction of certification system and the assessment system with the level of city and district, this system should be improved to meet the international certification standard.
