United Nations Framework Convention on Climate Change(UNFCCC), an international treaty to prevent the regulation and global warming, has passed through the General Assembly for 17 times from 1992 to 2011. To create a performance plan specific, such as the Kyoto Protocol, it is to promote the reduction of energy consumption and greenhouse gases worldwide. In South Korea, Korea Infrastructure Safety and Technology Corporation(KISTEC) is working and supporting for developing method of green remodeling policy. Among several solutions, "Remodeling" ensures to increase the energy efficiency of buildings and to reduce the emissions of greenhouse gases, and consequently it could maintain buildings high efficiency. For remodeling projects, it is most important to determine construction plan including remodeling scopes and methods, while the plan has been determined by the engineer's background and experience. Therefore, this study aims at developing a method for selecting optimal skin system which has remarkable influence to energy performance of the buildings.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

We set the representative balcony types of the existed building to two types: unexpanded balcony and extended balcony, and analyze the effect of reducing the cooling and heating energy load when applying remodeling. The scope of the study was limited to balcony walls, including window-wall junctions, and was conducted by comparing cases with and without thermal break insulation structures for a clear conclusion. The study was conducted using the equivalent U-value in each case. The equivalent U-value was calculated by deriving through 2 dimensional steady-state heat transfer analysis of each case balcony envelope. And building energy was calculated using the derived equivalent U-value. According to the calculation results, for unexpanded balconies, the equivalent U-value was reduced by about 80%, and the heating and cooling load was reduced by about 20%. In the case of extended balconies, the equivalent U-value was reduced by about 57% and the resulting heating and cooling load was reduced by about 12%.

Recently, solar control facade systems are highlighted due to its low cost and outstanding applicability for green remodeling. However, it has not been long time since the systems were introduced. Therefore, the application study of the solar control system also has been insufficient. In this study, simulated models were developed and three types of solar control systems(i.e., overhang, blind, and screen)are installed in the models. The efficiency of energy savings and investment payback period according to the application of solar control facade system were analyzed.

Energy systems in increasing energy efficiency are actively performed at home and abroad. But Generally systems in the country are limited in a new building or sort of some buildings like a public and office building. So, this research suggest a new direction of energy system for existing buildings. It need to set a new bound for containing the green remodeling. For a direction, we analysis domestic energy system in perform and compared their bounds, standard and methods of energy evaluation. This study is necessary for an additional research for proposing detailed evaluation items and for a feasibility study research. And it contribute to develope internal energy systems and set a new system bound.

Green remodeling of pubic buildings for improving indoor environment and reducing energy consumption is increasingly promoted. The objective of this study is to measure and analyze for wall's thermal performance, thermal transmittance, of existing buildings. The method of this present study refered the ISO 9869-1 and is to measured heat flow, surface temperature of wall, and in/outdoor temperature over 7 days. And it was compared the calculated thermal transmittance with measured one. The measured wall's thermal transmittance value is about two times than the calculated thermal transmittance value.

Since the late 20th century, countries of the world have made every effort to solve environmental problems due to global warming. The Korean Government has also made various efforts on reducing energy and $CO_2$ emission under the motto of "Low-Carbon Green Growth". In order to achieve the goal to reduce energy in the construction field, severe design standards and regulations on saving energy in new buildings have been established. However, for maximizing the reduction of energy in buildings, it is time to focus on deteriorated buildings where applications of energy saving designs and techniques have been insufficient. Especially, there are little guidelines and researches on reducing energy through remodeling at deteriorated school buildings which were built over 20 years ago. This paper suggests the priority of factors to reduce energy on the remodeling process at deteriorated school buildings using the AHP(Analytic Hierarchy Process) method. For applying the AHP method, the survey of staffs in the Education Offices and board members in the Korea Institute of Ecological Architecture and Environment was conducted via e-mail. As a result, factors of insulation, daylighting, system control, and windows turned out important in the energy reducing remodeling process at deteriorated school buildings, while factors of artificial lighting, solar heating, ventilation, and system did relatively unimportant.

The purpose of this study is to analyze the current condition of green building education, which is a necessary condition to activate green architecture, with the need to reduce greenhouse gas emissions in the building sector. The main results are as follows. First, the level of education and the level of domestic green architecture were generally underestimated. Second, in order to increase the satisfaction of participants in green building education, it is necessary to increase the number of courses and to increase the number of lecturers who have excellent practical skills. Third, there is a need to strengthen green building programs related to BEMS and green remodeling. Fourth, it is necessary to expand the education on green architecture for the people in the architectural planning and design field and the related field officials. Fifth, green building education needs to be implemented in conjunction with curriculum of elementary, middle and high school. Sixth, it is necessary to diversify the PR(public relations) channels of the green building education program and to provide a way to give the employment increase point when the curriculum is completed. Seventh, there is a need to expand administrative and financial incentives for green architecture in order to revitalize green architecture education.

골은 일생에 걸쳐 지속적인 재형성과장을 거치면서 유지되고 이러한 기전에 대한 연구는 골다공증을 비롯한 골대사 질환의 병태생리와 치료에 있어 큰 진전을 이루고 있다. 특히 생체 내 골형성 및 재생과정을 연구하는데 있어 형광표지자를 이용하는 방법이 널리 알려져 있는데, 그 중 calcein은 칼슘 킬레이터로 골이 새롭게 형성하는 부위에 녹색을 띔으로써 유용한 마커로 사용된다. 그러나 대부분의 골형성 연구에서 실험동물의 경우 표본제작을 할 때 크기가 작고 뼈가 부숴지기 쉬워 rat이나 rabbit을 이용하였으며, mice의 femur를 cross-section해서 관찰한 연구는 거의 없는 실정이다. 그래서 본 연구에서는 어린 mice를 실험동물로 이용하였으며, 생체 내 calcein을 4주간, 8주간 투여한 후 골 형성 변화를 형광현미경으로 관찰한 결과 8주차 쥐에서 4주차보다 진하고 골 형성 간격도 넓게 관찰된 것을 확인 할 수 있었다. Mice는 빠른 시일 내에 결과를 얻을 수 있고 부작용이 적은 장점이 있어서 앞으로 knock-out mice를 이용한 생체 내 실험에 활용하기 적합하다고 생각되며, 골형성 속도 평가 등 다양한 분야에서의 골 형성과 재생연구에 있어 기초 정보를 제공할 것으로 기대한다.
