The purpose of this study was to provide the fundamental data for the effective housing remodeling plan. Through the questionnaire survey, the actual conditions of remodeling in apartment housing were investigated. And as the result of statistic analysis, the relationships between characteristics of remodeling and building life-cycle, and family life-stage, were found out. The major findings of this study are as follows; 1) Most of apartment residents have remodeled the family living space and private living space. In detail, they performed remodeling frequently the change of finishing materials, facilities and equipments, and the change of the location of curtain wall ＆ storage fixtures. 2) It might be predicted that the building life-cycle was influential variable to predict apartment residents' remodeling. Therefore, in planning the support service for the remodeling, the building life-cycle should be taken into consideration.

Apartment Housing in Korea has been developed rapidly and settled as a main housing form for short period, 40 years. In spite of increase of the apartment housing, it has pointed out that spatial organization of the apartment housing could accommodate residents 'various life style and life cycle. One of such planning methods is a flexible housing. Starting with the Gangbyoun-Siebeom apartment, flexible housing has been developed as merchandising constantly. However, flexible housing doesn't have enough understanding concerning lifestyle or life cycle of user individually, and it also means lack of comprehension and of flexibility, layout from modular coordination and planning of housing component. Therefore, according to the flexibility, the major goal of this research is to analyze the difficulty in realizing further of flexible housing in Korea and suggest implementation and alternatives or directions of flexible housing in Korea.

With domestic construction projects becoming bigger, more specialized and more advanced, the construction industry is striving to improve quality and quantity, and is diversifying functions and shapes. Nevertheless, the process of a construction project causes problems when we estimate construction price, because the cost breakdown structures are different in each step. The primary aim of this study was to estimate building life cycle cost using the Delphi method. The cost breakdown structure for life cycle cost was classified into planning, design, construction, maintenance and waste disposal, and each detailed classification was determined by estimating life cycle cost. Moreover, the developed cost breakdown structure is verified by consulting with experts to secure objectivity and validity.

Using the 1995 Survey of Consumer Finances, this study investigates how family life-cycle stages and financial management practices affect household saving. First findings are that household income and householders education, race and ethnicity have significant effects on saving. Second, regarding the effect of the family life-cycle stages, younger married couples without children, middle pre-retired households without dependent children, and older households without dependent children are more likely to save than other similar households in the life-cycle stage of younger single households. Third, households with longer financial planning horizons, saving goals for retirement, purchase of durable goods and emergency goods, and low credit card debt are more likely to save. Based on the results, implications for financial management education and public policy are suggested.

The purpose of this study is to analyze the life cycle cost of primary cooling system by systematic support cost. Life Cycle Cost(LCC) is the process of making an economic assessment of an item, area, system, or facility by considering all significant costs of ownership over an economic life, expressed in terms of equivalent costs. The essence of life cycle costing is the analysis of equivalent costs of various alternative proposals. In order to select economical primary cooling system in early heat source plan stages, the research investigates cost items and cost characteristics during project process phases such as planning/design, construction, maintenance /management, and demolition/sell phases. The study also analyze the life cycle cost by capacity leading to suggest the most economical primary cooling system by systematic support cost.

Using the life cycle cost concept, optimum maintenance and retrofit planning for reliable seismic performance is suggested the overall life cycle cost to be minimized including the initial cost, the costs of inspection, repair, and failure. Limit states of the bridges are defined. And failure probabilities are computed through crossing theory. The effect of maintenance and retrofit is represented using the probability of damage detection and event tree analysis. Optimization of maintenance and retrofit planning method proposed from this research was applied to numerical examples. The analysis incorporates the acceleration and site conditions prescribed in the code, and the quality of inspection methods.

This study was to analyze the Life-Cycle Physical Activity Therapy Programs (PATPs) in Hoseo Region and to suggest the Activation of the program. The subjects were the 81 PATPs performed in 36 of the Community Health Centers in the region. The basic data was collected by Official Documents, the Homepage of the Centers, Telephone Interview, and e-mail with the person in charge of the programs. All the data were classified to the administrative districts (Rural, Urban-Rural Intergration and Urban Region), the Life Cycles (Children, Youth, Adult and Old Adult) and the Health-related Fitness Variables (Strength/Muscle endurance, Flexibility and Aerobics). The ACSM's (American College Sports Medicine) Guidelines for Exercise Testing and Prescription were used to evaluate the PATPs. In the results, the number of the PATPs was too low compared to the population. Also, the PATPs were not considered to the Life-Cycle proportion of the population. The management of the PATPs was principally inadequate. The frequency and duration of the PATPs were deficient in order to improve the Health-related Fitness. In conclusion, the number of the PATPs should be increased proportionally compared to the population, operated and developed on the Specificity of the Life-Cycle Population in the administrative districts. Further, the PATPs should be managed on the scientific knowledge of physical activity therapy.

The research team for the virtual construction development was established with the support of Korea Ministry of Construction and Transportation, and KICTEP (Korea Institute of Construction and Transportation Technology Evaluation and Planning). Its aims are to develop system that is to improve productivity & quality, to create a higher value-added business, and to cultivate international competitiveness in the construction industry. The virtual construction system is a design, engineering, and construction management information system that allows the project participants to effectively share the information throughout the construction life cycle with the support of 3D and design information. To achieve this, the research team focuses on developing several systems. First, the team focuses on developing for the pre-planning, the structural engineering, MEP, and the 3D based estimation system. Second, they focus on developing a simulation system for the construction process planning and feasibility study with help of the virtual reality technologies. Third, they focus on developing the CPLM (Construction Project Life-cycle Management) system for managing construction project data, and the decision support system that makes the collaboration among the project participants based on 3D technologies and information. We also focus on developing the SDAI (Standard Data Access Interface), the localized guideline for 3D design, and a training program. In addition, we focus on developing the undeveloped area of the commercial system and building an environment that can support the communication and collaboration in the construction life-cycle rather than developing the existing and commercialized system.
