"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.

Now, our country is in the face of increasement of aged person, and because of this fact many problems about aged person are show themselves. The main problems can be summarized as services provided by suppliers, inefficient management of welfare facility, violation of human rights, and nonprofessionalism of caring. Therefore to increasement of welfare quality, the direction of aged person welfare facility was suggested in this study.

Currently the industrialization, the urbanization, and the phenomenon of nuclear family is mainstream of korean society. And our country enter into an aging society, on the contrary. The concept of support for aged person is dwindled away. The main reason can be summarized as the aged person's consciousness and the family's economical burden. So, the concern about the facility for the aged person has being issued as a necessary factor to be considered by public. Therefore. the problems of the facility were analyzed and the improvement direction for them were suggested in this study.

This study is to design aged institutional household on a small scale, also the purpose of this study is to provide basic material for management of small scale institutional household and policy establishment that could help the aged well-being. Design of research is accomplished after the review of related literatures. The propositions of design are 3s follows; region：seoul suburbs(2 hours' distance) building：fourth stories(The building-to-land ratio 25％, capacious ratio 100％, in environmental affinity.) object：75 years and over aged 15 women cost：deposit and living month expenses contract between the manager and the desired occupant or concerned family term of validity：As long as occupant want.

Owing to increase of the large-scaled, high-raised and complexed building construction, the escape design of the building became very important issue to insure the safety of occupant. Specially, it is demanded to have building escape regulation considering for inconvenient movers such as disables elders pregnant women. However, building regulations for inconvenient movers are divided into "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information". But, for the escape security of inconvenient movers, the connection of each regulation are necessary. So this study suggested the improvement direction of the building escape regulation considering inconvenient movers through the compared analysis on the "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information".

In general, the seismic retrofit is almost essential to extend and remodel aged buildings. Because domestic seismic design code has been enhanced, seismic performance should be secure for aged building remodeling. Seismic response reduction device (damper) is lately appling to ensure seismic performance. This device is economical efficiency method that can reduce the load to foundation and the range of structural reinforcements, shorten of construction period. New shaped steel damper was applied for extension and remodeling construction for Boramae Deakyo building. As a result, the economy and shortening of construction period was achieved.

PURPOSES : The objective of this study is to investigate the properties of recycled asphalt binders with five different rejuvenators, in order to evaluate the applicability of the recycled asphalt binders compared with the original asphalt binder. METHODS : In order to simulate recycled asphalt binders, fresh asphalt binders are aged by various Superpave aging procedures, such as the rolling thin-film oven (RTFO) and the pressure aging vessel (PAV). Then, selected rejuvenators are added to the aged asphalt binders in the amount of 5%, 10%, and 15%. The asphalt binder properties are evaluated by the dynamic shear rheometer (DSR), the rotational viscometer (RV), and the bending beam rheometer (BBR). In this study, AP-5 (penetration grade 60-80, PG 64-16) asphalt binder is used. A total of five types of rejuvenators are employed. RESULTS AND CONCLUSIONS : When considering aged asphalt without a new asphalt binder, it seems that the percentage of rejuvenator used in Korea is a bit too low, and that it fails to possess the characteristics of the original binder. From the current practice of evaluating the properties of recycled binder based on penetration ratio only, the amount of rejuvenator required is similar for the long-term-aged binder, but is excessive for the longest-term aged binder, causing deterioration of workability and stiffness of the recycled binder.

As a building aged, overall performance considering structural safety, equipment safety and fire safety is lowering gradually. Since the building performance and the overall value of the building change as time elapse, exact safety performance of the building should be evaluated not only maintaining the building efficiently and also preventing disputes between buyer and seller of the building. We suggest major elements for assessing building's safety performance through surveying literatures, interviewing experts, reviewing existing assessment models, The assessment elements proposed here ate comprised of structural safety, equipment safety, fire safety, fire protection and fire escape, etc. This study helps to make a safety performance assessment criteria for a building.
