The purposes of the study were to try configuring categorization of floor plans of elderly centers located in apartment complexes and to find out the spatial transfigurations regarding floor plan types. The data for the analysis of the study were collected from 56 elderly centers of apartment complexes in Ulsan by observations and interviews from July 3 through 13, 2012. The results are as follows. Firstly, the floor plans of the elderly centers were categorized into six types, which were 2R+L+K, 2R+LK, 1R+L+K/1R+LK, 1RL+K, 1RLK, and 2R+K/1R+K(no living room). Secondly, there were no salient differences among the plan types for the characteristics of physical environment of the centers. The types of 2R+L+K were relatively big in size and two thirds of the centers had gender-segregated rooms. Lastly, spatial transfigurations was found in sixty-percent of the centers, which included change of spatial arrangement, functional change, and functional addition. Interestingly, the more the spaces were segregated, the more the spatial transfigurations were performed in the way for the integration of functions of the rooms.

Objectives: In this study, we started to develop an indoor garden integrated IoT solution based on IAQ (indoor air quality) and interconnection with an environmental database for smart management of indoor gardens. The purpose of this study was to develop and apply an integrated solution for customized air purification from an indoor garden through big data analysis using IoT technology. Methods: An IoT-based IAQ monitoring system was established in three households within a new apartment building. Based on real-time and long-term data collected, $PM_{2.5}$, $CO_2$, temperature, and humidity changes were compared to those of indoor garden applications and the analyzed results were indexed. Results As a result of the installation, all three households had no results exceeding the standard for indoor air pollution on average $PM_{2.5}$ and $CO_2$ indices. In the case of indoor garden installation, the IAQ index increased to the "Good" section after the installation, and readings in the "Bad" section shown before the installation disappeared. The comfort index also did not dip into the "Uncomfortable" section, where it had been preinstallation, and significantly lowered the average score from "Uncomfortable for sensitive groups" to "Good". Overall, the IAQ composite index for the generation of installations decreased the "Good" interval, but "Bad" did not appear. Conclusions In this study on developing an integrated solution for IAQ based on IoT indoor gardens, big data was analyzed to determine IAQ and comfort indexes and an IAQ composite index. Through this process, it became understood that it is necessary to monitor IAQ based on IoT.

Construction industry is faced with the problems such as the quickly changeable circumstance and increasing construction companies due to regulation mollification of company registration. In order to overcome these problems, new estimation system based on historical estimation cost is ready to introduce by government step by step. But the time of transition for estimation system causes another problems such as chaos addition to simultaneity of a standard of estimation system and new estimation system, lack of related regulation, accumulation of historical extensive cost data, and adjustment methodology when historical estimation data is applied to next projects. The purpose of this study is to suggest the change factors by activities for estimating historical cost for apartment housing projects. New estimation system is based on historical construction data. For application of this system, the standard adjustment methodology system is necessary. and extensive cost data should be accumulated under an unified construction work classification system. Therefore in this study, according to the construction work classification system, every apartment housing project was classified to 16 work classifications, and 7 major composed items which occupy more than 85% of construction costs are analyzed by detailed activities and by average ratio and maximum ratio each of them. In the result of the study, furniture work, foundation work and masonry work are the works which have big gap of costs between average ration and maximum ratio. In addition to suggestion of change factor by work species, 5 qualified construction specialists are interviewed and change factors in 7 major works are analyzed.

Purpose: Apartment housing should conduct a cyclic repair to keep and maintain the building performance since they are constructed. Therefore, the repair plan would be provided for long term period which explains the repair time, items and repair cost. Residents of apartment housing are responsible to pay for the repair activities. For repair cost, residents would reserve the money for repair little by little continuously until the required repair time because the repair cost takes a big burden for residents and lots of money a time. But, there is no systematic approach to provide the long term repair cost because it is no proper forecast of the repair cost to the upcoming repair time. In this study, it aimed at providing the monthly accumulation of the long term repair cost with the survey data in Seoul. Method: For these, the surveyed data are classified into 6 categories and number of data are 1,918. In addition, it developed the repair cost model for the 24 repair works and the cumulation function which is reflected with the each cost model. Result: This study are shown as follows : First, among the various estimation for the repair cost, the power function has a goodness of fit in statistics. Second, the monthly accumulation would be 12,840 won/household in size of $100,000m^2$ management area and $81.7won/m^2$ in size of the 1,000 household number during 40 years.

Purpose: At the moment, a lot of poor older people live in permanent rental housing in Korea. But many rental apartments are not suitable for elderly living because most of them have many problems related to the lack of accessibility and adaptability for older people with physical and mental disabilities. So it is necessary to upgrade the old permanent rental housing for convenience of elderly living. The purpose of this paper is to construct basic data for remodeling of worn out and small rental housing block in order to realize the concept of "Aging in Place". Methods: Questionnaires and interviews about elderly living have been conducted on 104 elderly who live in Suwon Wooman permanent rental apartment block which was constructed 21 years ago. From the collected data, dining pattern, inconvenient area, small area, satisfaction level on unit area and demand for unit expansion type have been analysed in order to find out the direction for remodeling of permanent rental apartment unit. Results: The problems of existing permanent rental apartment can be summarized into improper laundry space, small dining area, inconvenient bath and so on. According to the family size, the elderly resident has the different preference about the expansion type of his resident unit. Big families usually want to enlarge their living unit though they pay for additional monthly rental fee. Implications: Lifetime home concept adopting Universal Design has to be applied to the whole residential block especially to the social rental housing. And this concept had better be expanded to Lifetime neighbor design.
