In modern society, it is necessary to develop sustainable housing to protect environment. There should be a study on long life housing that satisfies living condition which residents require. Long life housing research is already activating in many developed countries. Although activation of long life housing is urgent, domestically, immaturity of technology development and law and system are barrier to progression of long life housing. Increase of early construction expenses is also problematic in activation of long life housing. The purpose of this research is to clarify a necessity of long life housing, to provide high quality of sustainable residence and to protect environment. This research also suggests a need of change from previous housing to long life housing. Moreover, it will look at related law and system of domestic long life housing and compare it to international law and system. From this comparison, it will point out a need of improvement and suggest appropriate long life housing system.

The desultory reconstruction of multi-family housing, no more than 20 years from the permit on the completion, have invited environmental disruption and extravagance of resource. To get over these problems, it is important to develop long-life housing, which is physically strengthened durability(long life) and functionally not outdated(remodeling ability). To activate Long-life housing, investigating current regulations on the long-life housing is as much important as the research on the technologies of long-life housing. To meet the raised, diverse, and varying needs of occupants, the research on the long-life housing must go side by side with the investigation on the regulations. So this research focused on the analysis of regulations and pratical revision of regulations to develop flexibility of the long life housing.

Many attention have been paid to the innovative technologies aiming at the paradigm shift such as the modular housing, pre-fabrication method, or long-life housing. Despite the government's efforts to diffuse the long-life housing, few case gained the high grades by applying various technologies required in the Long-life Housing Certification System. The concerns of cost increase and low profit are the main reason why most of the construction firms avoid the adoption of long-life housing. In this study, the variations of construction costs were analyzed according to the grades in the Long-life Housing Certification System. The results of this study will help the decision makers find the optimal solution in employing the long-life housing technologies during planning.

It is essential to maximize the advantages of long-life housing in consideration of the occupants' demands in order to promote the construction of long-life housing. The diverse plan types with flexibility should be developed based on those demands. Therefore, this study aims to review the level of awareness of long-life housing, and identify the customer needs by conducting the survey for the preference to pre-defined plan types. The results of survey are as follows: 1) Despite the enforcement of the Long-life Housing Certification System in 2014, the recognition among the customers about the long-life housing is still on the low level as shown in that 79.9% of respondents were not aware of the long-life housing; 2) For three alternative plan types, 78.5% on the integration type in front, 63.1% on the moving kitchen type, 47.0% on the Divided Housing type had intention to change; 3) 68.9% of the total are willingly ready to purchase the long-life housing under the condition of no difference in price between normal apartment and long-life housing. The less the number of family members is, the bigger this ratio of positive purchase intention is. Reflecting these results into the designs is expected to contribute to the enhancement of customer satisfaction as well as the diffusion of long-life housing.

PURPOSES : Long-life asphalt pavements are used widely in developed countries. In order to be able to devise an effective maintenance strategy for such pavements, in this study, we evaluated the performance of the long-life asphalt pavements constructed along the national highways in South Korea. Further, an economic evaluation of the long-life asphalt pavements was performed based on a life-cycle cost analysis. We aimed to devise a model for evaluating the performance of long-life asphalt pavements using the national highway pavement management system (PMS) database as well as for analyzing the economic feasibility of such pavements, in order to promote their use in South Korea. METHODS : The maintenance history and pavement performance data were obtained from the national highway PMS database. The pavement performances for a total of 292 sections of 10 lanes (5 northbound lanes and 5 eastbound lanes) of national highways were used in this study. Models to predict the performances of hot mix asphalt (HMA) and long-life asphalt pavements under two distinct traffic conditions were developed using a simple regression method. Further, the economic feasibility of long-life asphalt pavements was evaluated using the Korea Pavement Management System (KoPMS). RESULTS : We developed service-life prediction models based on the traffic volume and the equivalent of single-axle load and found that long-life asphalt pavements have service lives 50% longer than those of HMA pavements. Further, the results of the economic analysis showed that long-life asphalt pavements are superior in terms of various economic indexes, including user cost, delay cost, total cost, and user benefits, even though their maintenance cost is higher than that of HMA pavements. A comparison of the economic feasibilities of the various groups showed that group A is superior to HMA pavements in all aspects except in terms of the maintenance criterion (crack 20% or higher) as per the NPV index. However, the long-life asphalt pavements in group B were superior in terms of the maintenance criterion (crack 25% or higher) regardless of the economic feasibility. CONCLUSIONS : The service life of long-life asphalt pavements was found to be approximately 50% longer than that of HMA pavements, regardless of the traffic volume characteristics. The economic feasibility of long-life asphalt pavements was evaluated based on the KoPMS. The results of the economic analysis were the following: long-life asphalt pavements are exceptional in terms of almost all factors, such as user cost, delay cost, total cost, and user benefit; however, the exception is the maintenance cost. Further, the economic feasibility of the long-life asphalt pavements in group B was found to be better than that of the HMA pavements (crack 25% or higher).

Domestic apartment housing has been designed in accordance with the new housing supply-driven policies for a long time. As a result, its design, material production, construction, maintenance and remodeling process, rather than being systematically performed, were individually approached to cause insufficient linkage between technologies. For these problems and the supply of long life housing, active research on long life housing has been conducted in Korea since 2005. However, the existing research on long life housing has been focused on a single item with no connection made between infill systems, and no overall interface rule, resulting in no activation of the business. In this study, for the supply and activation of long life housing, we aim to analyze the problems of existing long life housing to set up its matching standards for infill systems.

Life-long housing refers to housing units whose performance is certified by the head of a Life-long Housing certification authority with respect to durability, variability and ease of repair. Since life-long housing should be able to meet residents' demands for changes in living space, the space of the housing should be able to be varied by using a dry construction method, instead of a wet construction method. For life-long housing to be approved, the installation of infill systems that life-long housing certification standards is needed. At present, apartment houses are being constructed only in accordance with the general rating, which is the lowest rating in the life-long housing certification system. The reason for this is that, since the infill system was created, it has not yet been actively used due to a rise in construction costs when infill products are utilized. In this regard, this study seeks to propose ways to optimize infill usage and create scenarios that can minimize the costs of life-long housing construction, taking into consideration variations in construction costs based on the characteristics of infill systems applied to housing.

The purpose of this study was to comprehend specific characteristic of interface and present the standardized interface of Long Life Housing, which could be obtained by the total and various approaches. With this in mind we analyzed related studies of interface through previous studies, and based on the analysis we created standardized factors of categorization in view of characteristic of interface. Using these factors, we can determine whether the interface could be used systematically in Long Life Housing. And as these were presented in the form of Key Map for expedite the synthetic understanding of interface, we could easily reconize types of interface. Especially, we only dealt the wall of flexible interface of Long Life Housing. Throughout systemizing and standardizing works, we can expedite the understanding of interface of Long Life Housing and finally, we want to make basic data used for date base of interface which can be available for Long Life Housing.
